I’ve used Windows for as long as I’ve been alive. At 6 years old, my first com­puter was a Windows 98 ma­chine, with an Athlon XP 1900+ (Palomino core) and a GeForce 440 MX, blessed with a gen­er­ous 256 megabytes of RAM.

Looking back, I kinda got scammed with that graph­ics card, but what could I do? I was a silly kid. (The miss­ing shader sup­port came back to bite me in the ass)

Also, is it weird that I still re­mem­ber the specs of my first com­puter, 22 years later?

Anyway, Windows has been fa­mil­iar and com­fort­able. I knew all the workarounds and how to ex­tract max­i­mum ef­fi­ciency from it.

I was a happy user, for over 20 years, and Windows has been my go-to for every­thing com­puter-re­lated.

Even af­ter be­com­ing a soft­ware de­vel­oper and us­ing a mac­book, I’d still find my­self reach­ing for Windows at times.

That is, un­til Microsoft de­cided to turn it into some­thing com­pletely un­rec­og­niz­able and un­us­able.

I think it started with the Windows 10 full-screen ads.

You know, those friendly sug­ges­tions telling you to try OneDrive or to “use the rec­om­mended browser set­tings” (reads as “please try Edge and OneDrive, we’re des­per­ate”).

Actually, scratch that, I think it re­ally started with the non-con­sen­sual up­dates:

Oh you’re do­ing work? That’s so cute… we’re gonna close what­ever apps you had open, be­cause we’re up­dat­ing now. We own your com­puter.

You had un­saved work? Too bad, it’s gone, get bent.

At first I ig­nored it, and car­ried on as nor­mal. Sure, I’d get mad from time to time and I’d com­plain.

But hey, noth­ing beats the con­ve­nience of be­ing able to have all of your ap­pli­ca­tions in one place

My break­ing point came with the 24H2 up­date. It in­stalled on my sys­tem with­out my con­sent, like any other ma­jor up­date. I knew there were prob­lems with it, peo­ple were al­ready com­plain­ing on Reddit, so I just post­poned it, and kept post­pon­ing it.

All it took was for me to leave my com­puter on and un­at­tended for a while, and BOOM, just like that - the ma­jor OS up­date that no­body wanted, it was on my com­puter.

As soon as 24H2 landed on my ma­chine, I en­coun­tered a bug so bizarre I thought I was los­ing my mar­bles.

If Chrome was po­si­tioned un­der any other win­dow, it would start hav­ing what I can only de­scribe as a vi­sual seizure.

Here’s Ableton Live with Chrome (Reddit) un­der it:

Worse, there was a de­cent chance this would trig­ger a full sys­tem lock, leav­ing me smash­ing my desk in im­po­tent rage. I shit you not.

I tried to roll­back. The roll­back failed with an er­ror. I re­in­stalled Windows. The bug per­sisted.

Like dig­i­tal her­pes, I just could­n’t get rid of it.

The so­lu­tion? Installing an Insider build. Yes, the so­lu­tion to Microsoft’s bro­ken sta­ble re­lease was to use their un­sta­ble re­lease.

For the Windows Defenders (see what I did there?), I tried unin­stalling the dis­play dri­vers with DDU, and test­ing other ver­sions. It did­n’t help.

Either I stayed for­ever on the older build, or I’d have to deal with this. And don’t tell me to for­ever dis­able up­dates, I’ll com­pletely lose it.

The Insider build worked…sort of. But now I had a new bug: Chrome would ran­domly lock up for about 30 sec­onds when a video was play­ing. My op­tions were to wait it out or press Ctrl+Alt+Delete and Esc to force my way back to a work­ing browser. After some dig­ging, I dis­cov­ered this was caused by an NVIDIA-Microsoft dri­ver in­com­pat­i­bil­ity.

I’ve found out that the flick­ers and the chrome lock-up is­sues are likely caused by the Multiplane Overlay (MPO) pipeline. Microsoft blamed NVIDIA for not cor­rectly im­ple­ment­ing it in their dri­vers. NVIDIA blamed Microsoft. What’s clear is that if you were fac­ing this is­sue, you were es­sen­tially screwed be­cause these 2 com­pa­nies would just pass the hot potato to each other.

I should men­tion that this bug per­sisted even af­ter I went off the Insider build and on 25H2. And when I posted on r/​Mi­crosoft, they just deleted it.

The lat­est and great­est OS surely can­not be bro­ken be­yond re­pair, surely I’m us­ing my PC wrong.

So there I was, fi­nally grasp­ing the re­al­ity of what you’re up against, as a Windows user:

* Updates that in­stall with­out per­mis­sion and brick my sys­tem

* Copilot and OneDrive ads ap­pear­ing in every cor­ner of the OS

* Copilot but­tons every­where, com­ing for every ap­pli­ca­tion

* Can’t even make a lo­cal ac­count with­out hack­ing the setup with Rufus (they even re­moved the ter­mi­nal workaround)

* Zero ac­tion­able fixes or even an aknowl­edg­ment of their fuck­ups

People of­ten say Linux is “too much work.”.

And I agree. They’re com­pletely jus­ti­fied to com­plain. There’s the doc­u­men­ta­tion page div­ing, the fo­rums, the red­dit threads. And, most im­por­tantly, you have to ba­si­cally rewire your brain and stop ex­pect­ing it to be­have like Windows used to.

But I looked at the list above and re­al­ized: Windows is now also too much work.

And the dif­fer­ence with Windows is that you’re go­ing to do all that work while ac­tively fight­ing your com­puter only for it to be un­done when the next sur­prise up­date comes and ru­ins every­thing.

You might be think­ing “just dis­able up­dates, man” or “just in­stall LTSC”, or “just run some ran­dom de­bloat script off of GitHub”.

Why? Why would I jump through all these hoops? I’d rather put in the ef­fort for an OS that knows what con­sent is and re­spects me as a user.

To set the stage: I’m a soft­ware de­vel­oper and a mu­si­cian.

As you can imag­ine, I was le­git­i­mately wor­ried about app sup­port on Linux, and how it would dis­trupt my work­flow.

But af­ter Chrome crash­ing for the 10000th time, I said “enough is enough”, and de­cided to go big. I in­stalled CachyOS, a per­for­mance-fo­cused Arch-based dis­tri­b­u­tion, on my main ma­chine (9800X3D, RTX 5080).

It was­n’t a pain­less process. In fact, sleep mode was bro­ken from the start, and my sys­tem would fail to de­tect the mon­i­tor af­ter wak­ing up.

What’s more, Ableton Live does not have a na­tive Linux build, only Windows and ma­cOS. So I could­n’t use it any­more, at least not with­out fuck­ing around with Wine (which does­n’t fully sup­port it), or with­out keep­ing a Windows VM and tak­ing an L on au­dio la­tency.

But un­like Windows, on CachyOS I could ac­tu­ally fix my NVIDIA woes by fol­low­ing this thread on their fo­rum.

All I had to do was add the NVIDIA mod­ules to mkinitc­pio. One con­fig change, a com­mand to re­build the initramfs, and prob­lem solved.

I also found a good na­tive al­ter­na­tive to Ableton Live - Bitwig Studio, which both­ered to re­lease a na­tive Linux Build.

Thanks to the con­stant progress that was made with Pipewire, I’m get­ting au­dio la­tency on par with Mac OS, and lower than Windows. And my work­flow did­n’t even change that much, since Bitwig is made by ex-Able­ton de­vel­op­ers that seem to give a shit.

As for my de­vel­op­ment tools, on Windows you al­ready ac­cept the fact that you WILL use WSL or docker, so re­al­is­ti­cally I just cut the bro­ken mid­dle­man.

Now com­pare that to the Windows fuck­ery above.

If 3 years ago you would have told me that Microsoft would sin­gle­hand­edly sab­o­tage their own OS, do­ing more Linux mar­ket­ing than the most neck­bearded Linux fan­boy (or the most fem­boy Thinkpad en­joyer), I’d have laughed in your face, called you delu­sional, and then hurled some more in­sults your way.

Yet here we are, I’ve been dual-boot­ing CachyOS for over a year, and in the last month I’ve been us­ing it ex­clu­sively.

If you’re think­ing about mak­ing the switch, I’d rec­om­mend you do a lit­tle re­search first.

Look up the trade­offs be­tween a rolling re­lease dis­tro and a sta­ble re­lease, it might just save you a headache.

For me, the fast up­dates of Cachy/Arch are a good thing, but you can imag­ine that you are ef­fec­tively trad­ing sta­bil­ity for new fea­tures.

So what is the ac­tual state of Linux in 2026, from my hon­est per­spec­tive?

All ma­jor browsers (Chrome, Firefox, Edge, Brave) have na­tive Linux builds. Full sup­port. No com­pro­mises.

Video play­back works flaw­lessly, with hard­ware ac­cel­er­a­tion even. On AMD, on NVidia and yes, on Intel too.

Linux is the pre­ferred plat­form for de­vel­op­ment.

Better ter­mi­nal sup­port, na­tive pack­age man­agers, Docker runs na­tively with­out the WSL over­head, and your pro­duc­tion servers are prob­a­bly run­ning Linux any­way.

Hell, even Microsoft has their own Linux dis­tro, Azure Linux (Formerly CBL-Mariner).

This is where peo­ple as­sume Linux falls short. And they’re right, but not com­pletely:

* Adobe Suite: Runs via Winboat. Far from per­fect (no video ac­cel­er­a­tion, laggy at times), but func­tional

So while con­tent cre­ation is vi­able, the com­pro­mises might be deal­break­ers.

* Audio la­tency: Thanks to PipeWire, Linux au­dio la­tency is ac­tu­ally lower than Windows

Here’s where things get in­ter­est­ing. The per­cep­tion is that gam­ing on Linux is a no-go. In 2026, that’s in­creas­ingly un­true:

* Proton/Wine: Pretty much all games with­out ker­nel-level anti-cheat work out of the box through Steam’s Proton com­pat­i­bil­ity layer

* Performance: For AMD GPUs, gam­ing per­for­mance is on par with Windows, on av­er­age

* NVIDIA: There was a 10-30% per­for­mance penalty on Intel/NVIDIA GPU se­tups, but re­cent Vulkan ex­ten­sions are tak­ing care of that.

NVIDIA has re­leased beta dri­vers mak­ing use of these im­prove­ments, and once Wine/DXVK/Proton are up­dated to make use of the ex­ten­sions, the per­for­mance delta should be es­sen­tially gone

The only real lim­i­ta­tion is that some games with anti-cheat like Valorant, Call of Duty or League of Legends won’t run. But hon­estly I think not be­ing able to launch League of Legends is ac­tu­ally a fea­ture - one fi­nal rea­son to in­stall Linux.

It’s not all bad, though. Arc Raiders makes use of Easy Anti-Cheat, yet runs flaw­lessly. In fact, I’ve been play­ing it like a mad­man. It goes to show that if the de­vel­op­ers want to, it’s pos­si­ble.

Still falls short com­pared to Windows and Mac OS (Autodesk, I’m look­ing at you).

The sil­ver lin­ing is that Blender has a na­tive build. So if it’s your main ap­pli­ca­tion, you’re good to go.

Basic op­er­a­tions are so much faster on Linux. Opening di­rec­to­ries, launch­ing ap­pli­ca­tions, sys­tem re­spon­sive­ness. It’s like your com­puter took a line of coke, and is now ready to work.

No more wait­ing for the Start menu to de­cide it wants to open. No more File Explorer hang­ing when you need it the most.

Since we’re on the topic of Linux im­prove­ments, I want to ad­dress the ele­phant in the room - peo­ple who keep say­ing “I want to switch”, but keep mov­ing the goal­posts:

“Okay, but what about Y?”

If you’re al­ways find­ing the next rea­son not to switch, you’re not look­ing for so­lu­tions, you’re look­ing for ex­cuses to stay com­pla­cent.

I was that per­son, so I would know.

At the same time, I want to take it down a notch and say that there are still plenty of use cases (Especially cre­ative work, and like stated pre­vi­ously, 3D mod­el­ling and also Game Dev) where it sim­ply does­n’t make sense to switch.

So if you’re in that sce­nario, don’t feel pres­sured, just wait for things to im­prove.

And if you don’t plan on ever switch­ing, more power to you.

I’m not here to judge, just here to vent my Microsoft frus­tra­tions.

And I did­n’t re­ally want to switch ei­ther, be­cause who wants to re-learn how their com­puter should be op­er­ated from scratch? What I re­ally wanted was for Windows to work, but Microsoft did­n’t.

While I’m en­joy­ing my new Linux setup, Windows 11 is hav­ing a mis­er­able year, and we’re only a month in!

According to Windows Latest, there were over 20 ma­jor up­date prob­lems in 2025 alone, and 2026 is start­ing off strong, with the January up­date caus­ing black screens and Outlook crashes.

Here’s a quick 2025 Spotify Wrapped of the bugs Windows users dealt with:

* The Copilot app ac­ci­den­tally get­ting deleted (okay, this is ac­tu­ally a good change for once)

And the com­pa­ny’s re­sponse? Crickets. They’re busy boast­ing that 30% of their code is cur­rently be­ing writ­ten by AI. Don’t worry, Microsoft, we can def­i­nitely tell.

For the re­main­der of 2026, Microsoft is cook­ing up a big one: re­plac­ing more and more na­tive apps with React Native. But don’t let the name fool you, it’s never go­ing to be as close to na­tive as the real thing. These are pro­jects de­signed to be eas­ily ported across any ma­chine and ar­chi­tec­ture by mak­ing use of JavaScript.

And each one spawns its own Chromium process, gob­bling up your RAM so you can en­joy the priv­i­lege of open­ing the Settings app. And each one of these apps cre­ates an in­stance of V8 or Hermes per app, which adds ad­di­tional over­head (RAM + CPU). I’d ar­gue you do not need that over­head just to open a Settings app.

I could maybe un­der­stand this for a weather wid­get. But when it’s com­ing for core sys­tem apps, I think it’s just lazy.

I’m gonna go full con­spir­acy nut here, but I bet it’s be­cause it’s eas­ier for LLMs to write JavaScript, and Microsoft can’t be asked to pay ac­tual hu­mans to write (and test) proper na­tive code.

Meanwhile, en­tire gov­ern­ments are aban­don­ing Windows for Linux, the term “Microslop” is trend­ing on so­cial me­dia, and Windows 11′s rep­u­ta­tion is at its low­est point ever.

So here I am. Fully switched to Linux.

Not be­cause I’m some open-source ide­al­ist or com­mand-line war­rior (I’m just some guy), but be­cause Microsoft turned into Microslop.

Recently, Microsoft CEO Satya Nadella wrote a blog post ask­ing peo­ple to stop call­ing AI-generated con­tent “slop” and to think of AI as “bicycles for the mind.”

Apple has set a new dead­line of November 1, 2026 for all Patreon cre­ators to switch from Patreon’s legacy billing sys­tem to the App Store’s in-app pur­chase sys­tem in the Patreon app on the iPhone and iPad, as re­ported by TechCrunch.

Note: This im­age has been edited to in­clude a pile of cash.

Patreon is a plat­form where cre­ators such as YouTubers can re­ceive pay­ments from fans, which can be a valu­able rev­enue stream along­side ads and spon­sor­ships.

Apple ini­tially told Patreon that its cre­ators must move to the App Store’s in-app pur­chase sys­tem by November 2025, or else Patreon would risk re­moval from the App Store, but the dead­line was pushed back. Apple con­sid­ers pay­ments from sup­port­ers to cre­ators on Patreon to be dig­i­tal goods that it is en­ti­tled to re­ceive a com­mis­sion on.

Apple re­ceives a 30% com­mis­sion on in-app pur­chases and sub­scrip­tions, but this drops to 15% for a sub­scrip­tion that has been on­go­ing for more than a year.

Patreon gives cre­ators the op­tion to ei­ther in­crease their prices in the iOS app only, or ab­sorb the fee them­selves, keep­ing prices the same across plat­forms.

On the iPhone and iPad, Patreon users who wish to sup­port a cre­ator can side­step the App Store’s com­mis­sion by com­plet­ing their pay­ment via Patreon’s web­site.

Patreon said it is dis­ap­pointed with how Apple has nav­i­gated this pol­icy.

According to TechCrunch, only 4% of Patreon cre­ators are still us­ing the plat­for­m’s legacy billing sys­tem, with the rest hav­ing al­ready switched over.

Patreon has shared a FAQ with more de­tails for cre­ators.

FBI Director Kash Patel said Monday that he had opened an in­ves­ti­ga­tion into the Signal group text chats that Minnesota res­i­dents are us­ing to share in­for­ma­tion about fed­eral im­mi­gra­tion agents’ move­ments, launch­ing a new front in the Trump ad­min­is­tra­tion’s con­flict there with po­ten­tial free speech im­pli­ca­tions.

Patel said in an in­ter­view with con­ser­v­a­tive pod­caster Benny Johnson that he wanted to know whether any Minnesota res­i­dents had put fed­eral agents “in har­m’s way” with ac­tiv­i­ties such as shar­ing agents’ li­cense plate num­bers and lo­ca­tions.

“You can­not cre­ate a sce­nario that il­le­gally en­traps and puts law en­force­ment in har­m’s way,” he said in the in­ter­view, which was posted to YouTube.

The in­ves­ti­ga­tion quickly drew skep­ti­cism from free speech ad­vo­cates who said the First Amendment pro­tects mem­bers of the pub­lic who share legally ob­tained in­for­ma­tion, such as the names of fed­eral agents or where they are con­duct­ing en­force­ment op­er­a­tions.

“There are le­git­i­mate rea­sons to share such in­for­ma­tion, in­clud­ing en­abling mem­bers of the pub­lic to ob­serve and doc­u­ment law en­force­ment ac­tiv­ity and to hold of­fi­cials ac­count­able for mis­con­duct,” Aaron Terr, di­rec­tor of pub­lic ad­vo­cacy at the Foundation for Individual Rights and Expression, said in an email.

“Given this ad­min­is­tra­tion’s poor track record of dis­tin­guish­ing pro­tected speech from crim­i­nal con­duct, any in­ves­ti­ga­tion like this de­serves very close scrutiny,” he said.

For months, dig­i­tal tools have been at the cen­ter of how peo­ple have pushed back against im­mi­gra­tion en­force­ment ef­forts in Minnesota and across the coun­try. The ad­min­is­tra­tion’s op­po­nents have used group text chats to track Immigration and Customs Enforcement op­er­a­tions, share pho­tos of sus­pected ICE ve­hi­cles and raise aware­ness for neigh­bors. In June, ad­min­is­tra­tion of­fi­cials crit­i­cized ICEBlock, an app de­signed to share in­for­ma­tion about ICE sight­ings. Apple re­moved the app from its app store in October, prompt­ing a law­suit from the ap­p’s de­vel­oper al­leg­ing the ad­min­is­tra­tion un­law­fully pres­sured Apple to re­move it.

In the past few days, the group text chats — es­pe­cially those on the en­crypted mes­sag­ing app Signal — have drawn at­ten­tion from right-wing me­dia. On Saturday, Cam Higby, a con­ser­v­a­tive jour­nal­ist based near Seattle, said in a thread on X that he had “infiltrated” Signal groups from around Minneapolis that he al­leged were ob­struct­ing law en­force­ment. His thread, which got 20 mil­lion views, fo­cused on how the groups share such in­for­ma­tion as the li­cense plate num­bers of sus­pected fed­eral ve­hi­cles. NBC News has not ver­i­fied Higby’s claims.

Patel said he got the idea for the in­ves­ti­ga­tion from Higby.

“As soon as Higby put that post out, I opened an in­ves­ti­ga­tion on it,” he said. “We im­me­di­ately opened up that in­ves­ti­ga­tion, be­cause that sort of Signal chat — be­ing co­or­di­nated with in­di­vid­u­als not just lo­cally in Minnesota, but maybe even around the coun­try — if that leads to a break in the fed­eral statute or a vi­o­la­tion of some law, then we are go­ing to ar­rest peo­ple.”

The Signal Foundation, the non­profit or­ga­ni­za­tion that op­er­ates the Signal app, did not im­me­di­ately re­spond to a re­quest for com­ment.

Signal, which is con­sid­ered one of the most se­cure chat apps, is a go-to re­source for peo­ple con­cerned about pri­vacy. It is per­haps best known as the app Defense Secretary Pete Hegseth used to share sen­si­tive mil­i­tary in­for­ma­tion last year in a group chat that ac­ci­den­tally in­cluded a jour­nal­ist.

In the Twin Cities, Signal group chats have been a stan­dard part of toolk­its — along with walkie-talkies and whis­tles — used by ac­tivists, par­ents and neigh­bor­hood-watch mem­bers who have or­ga­nized as vol­un­teers to warn fam­i­lies about im­mi­gra­tion en­force­ment ac­tiv­i­ties by re­lay­ing real-time in­for­ma­tion, es­pe­cially near schools. Patrol vol­un­teers have said that, with more than 3,000 fed­eral im­mi­gra­tion agents in Minnesota, they are mo­ti­vated by a de­sire to pro­tect par­ents, chil­dren and school staff mem­bers who are not U. S. cit­i­zens.

Patel did not say which laws he thought Minnesota res­i­dents may have vi­o­lated. An FBI spokesper­son said the bu­reau had no fur­ther in­for­ma­tion to pro­vide.

The an­nounce­ment seemed likely to have im­pli­ca­tions for the First Amendment’s guar­an­tee of free speech. Alex Abdo, lit­i­ga­tion di­rec­tor at the Knight First Amendment Institute at Columbia University, said the First Amendment pro­tects the right to record law en­force­ment of­fi­cers as they carry out their of­fi­cial re­spon­si­bil­i­ties.

“The abil­ity of every­day cit­i­zens to hold gov­ern­ment agents to ac­count, by ob­serv­ing them and ad­vo­cat­ing for change, is what has dis­tin­guished the American ex­per­i­ment with democ­racy from au­thor­i­tar­ian regimes around the world,” Abdo said in an email.

“Unless the FBI has ev­i­dence of a crime, and not just ev­i­dence of ac­tiv­ity the Constitution pro­tects, it should stand down,” he said.

Patel ac­knowl­edged in the in­ter­view with Johnson that an in­ves­ti­ga­tion into group text chats would raise free speech con­cerns and said the FBI would “balance” the rights guar­an­teed by the First and Second amend­ments with what he said were po­ten­tial vi­o­la­tions of fed­eral law.

“Now, we will bal­ance the First and Second amend­ment con­stantly, but we have to let the com­mu­nity know that we will not tol­er­ate acts of vi­o­lence and an es­ca­la­tion and a vi­o­la­tion of the fed­eral code,” he said. The Second Amendment could be at is­sue be­cause Alex Pretti, the nurse shot and killed by a fed­eral agent Saturday in Minneapolis, was per­mit­ted to carry a gun in pub­lic and had one with him.

Terr, of the Foundation for Individual Rights and Expression, said the gov­ern­ment does not get to “balance” the First Amendment against its other in­ter­ests.

“The Constitution takes prece­dence over any con­flict­ing state or fed­eral law, and over any of­fi­cial’s de­sire to sup­press speech they dis­like,” he said in his email.

He added: “There is a First Amendment ex­cep­tion for speech in­tended and likely to pro­voke im­mi­nent un­law­ful ac­tion, but that does­n’t ap­ply to just any speech the gov­ern­ment claims puts of­fi­cials in har­m’s way. By con­trast, if in­di­vid­u­als are threat­en­ing fed­eral agents or con­spir­ing to phys­i­cally harm them, that is il­le­gal. But con­spir­acy re­quires an agree­ment to com­mit a spe­cific crime and a sub­stan­tial step to­ward car­ry­ing it out.”

Patel also said the FBI had made “substantial progress” in an in­ves­ti­ga­tion into groups and peo­ple re­spon­si­ble for fund­ing re­sis­tance to im­mi­gra­tion en­force­ment. He al­leged that the protests and neigh­bor­hood mon­i­tor­ing are “not hap­pen­ing or­gan­i­cally” but did not im­me­di­ately pro­vide ev­i­dence.

Vitamin D & Omega-3 have a larger ef­fect on de­pres­sion than an­ti­de­pres­sants

⏱ This post is over years old.

Proceed at own risk.

The “effect size” of the best an­ti­de­pres­sants on de­pres­sion, vs placebo, is around 0.4. (On av­er­age; some peo­ple re­spond much bet­ter or much worse.) This is like go­ing from a C to a C+.

In con­trast: the ef­fect size of 1500 mg/​day of “≥60% EPA” Omega-3 sup­ple­ments is a bit higher, around 0.6. This is like go­ing from a C to a B–. (With un­cer­tainty; at worst, Omega-3′s “only” on par with an­ti­de­pres­sants.)

But, much bet­ter: the ef­fect size of 4000 IU/day of Vitamin D is twice as high as an­ti­de­pres­sants’, around 1.0. This is like go­ing from a C to an B! (With un­cer­tainty; at worst, Vitamin D’s “only” on par with an­ti­de­pres­sants.) This works even for peo­ple who don’t have a Vitamin D in­suf­fi­ciency — but around half of American adults do.

Even if you’re al­ready tak­ing Vitamin D & Omega-3, dou­ble check your dose: it may still not be enough! The of­fi­cial rec­om­men­da­tions are all too low, and re­cent re­search sug­gests even the of­fi­cial max­i­mum safe dose for Vitamin D is too low.

I know the “yay sup­ple­ments” genre of writ­ing is full of sloppy re­search & grifters, and you should be skep­ti­cal of my claim of easy wins, of “$100 bills lay­ing on the side­walk”. But there is good sci­ence among the trash, and pol­icy is of­ten decades be­hind sci­ence in any field, not just health.

So, Vitamin D & Omega-3: pos­si­bly high re­ward, for low risk. That’s a pos­i­tive “expected value” bet! These sup­ple­ments are safe, cheap, over-the-counter, and have pos­i­tive side-ef­fects (on Covid & cog­ni­tion). As al­ways, “ask your doc­tor”, show them the peer-re­viewed pa­pers cited in this post.

Unless you have spe­cific rea­sons to not take Vitamin D & Omega-3 — kid­ney stones, blood thin­ners, etc — please try them, for at least a month! They could save your men­tal health. Maybe even your life.

In Alicetown, the av­er­age per­son has 4 younger cousins.

In Bobtown, the av­er­age per­son has 3 younger cousins.

Alright, not so sur­pris­ing. You may not even no­tice a dif­fer­ence.

In Alicetown, the av­er­age per­son has 4 limbs.

In Bobtown, the av­er­age per­son has 3 limbs.

It’s the same ab­solute dif­fer­ence (4 vs 3) and rel­a­tive dif­fer­ence (3/4). So what makes limbs more sur­pris­ing than cousins? Well, partly it’s more dra­matic & vis­i­ble, but also be­cause: we ex­pect high vari­a­tion in the num­ber of some­one’s younger cousins, but not their num­ber of limbs.

This is why sci­en­tists cal­cu­late an “effect size” or “standardized mean dif­fer­ence” (“mean” = av­er­age). We take the dif­fer­ence be­tween two groups, then di­vide by the to­tal amount of vari­a­tion, to ac­count for how sur­pris­ing a dif­fer­ence is.

Unfortunately for laypeo­ple, the ef­fect size is usu­ally just re­ported as a num­ber, like “+0.74” for spac­ing out your study­ing vs cram­ming, or “–0.776″ for sleep de­pri­va­tion on at­ten­tion.

But what’s that mean? How can we make these num­bers in­tu­itive?

Well, a com­mon way for data to be is a bell-shaped curve (also called a “normal dis­tri­b­u­tion”). And most of us are, alas, well-ac­quainted with the bell curve in school grades. (“grading on a curve”)

So: school grades give us a use­ful way to think about stan­dard­ized ef­fect sizes! We can now con­vert that num­ber into an ac­tual let­ter grade:

For ex­am­ple: spac­ing out your study­ing, rel­a­tive to cram­ming, will on av­er­age lift your test scores from a C to a B–. (effect size = +0.74) And short-term sleep de­pri­va­tion, rel­a­tive to healthy sleep, will on av­er­age tank your abil­ity to pay at­ten­tion from a C to a D+. (effect size: –0.776)

But it’s not lim­ited to just grades & aca­d­e­mic per­for­mance. Effect sizes can also help us un­der­stand any kind of dif­fer­ence be­tween groups, in ob­ser­va­tion or in ex­per­i­ments!

Let’s use our school grade anal­ogy, to in­ter­pret ef­fect sizes on men­tal health:

What’s an “F in men­tal health”? By de­f­i­n­i­tion of a bell curve, ~2.3% of peo­ple are be­low –2 sigma (an “F”). (See: this bell curve cal­cu­la­tor.) In Canada, ~2.6% of peo­ple had sui­ci­dal ideation in 2022, while in the US, it was ~4.9% in 2019. So, it’s not too far off to say: “F in men­tal health = lit­er­ally sui­ci­dal”. (Also, re­minder that ~4% is 1-in-25 peo­ple. You likely know some­one, or are some­one, who will feel sui­ci­dal this year. Please reach out to your friends & loved ones!)

What’s a “D in men­tal health”? ~16% of peo­ple are be­low –1 sigma (a “D”) on a bell curve. The Keyes 2002 study es­ti­mated that ~14.1% of adults meet the DSM-III cri­te­ria for a ma­jor de­pres­sive episode. So, D = Depressed.

What’s an av­er­age “C in men­tal health”? ~68% of peo­ple are within a sigma of av­er­age (a “C”) on a bell curve. Same above study found that 56.6 per­cent had mod­er­ate men­tal health. They were nei­ther “languishing” nor “flourishing”. I guess C = Could Be Worse.

What’s a “B in men­tal health”? ~16% of peo­ple are above +1 sigma (a “B”) on a bell curve. Same above study found that 17.2% of adults are “flourishing”. Good for them! B = Flourishing, life is good.

What’s an “A in men­tal health”? I don’t know who these freaks are. I ac­tu­ally could not find any sci­en­tific stud­ies on “the +2 sigma in well-be­ing”. In con­trast, there’s lots of re­search on sui­ci­dal ideation, the –2 sigma in well-be­ing. In the ab­sence of any ac­tual data, I’ll just say: A = AWESOME

So, if an in­ter­ven­tion is found to have an ef­fect size of +1.0, that’s like go­ing up a let­ter grade. If some­thing’s found to have an ef­fect size of -2.0, that’s like go­ing down two let­ter grades. And so on.

Okay, so how do we get peo­ples’ “mental health grades” up?

Let’s look at an­ti­de­pres­sants, Omega-3, and Vitamin D, in turn:

The good news is they work. The bad news is they don’t work as well as you’d think they may work.

Cipriani et al 2018 is a meta-analy­sis: a study that col­lects & com­bines lots of pre­vi­ous stud­ies (that pass some ba­sic cri­te­ria, to min­i­mize a garbage-in-garbage-out sit­u­a­tion). While meta-analy­ses aren’t per­fect, it’s usu­ally bet­ter for “science com­mu­ni­ca­tors” like me to cite meta-analy­ses over in­di­vid­ual stud­ies, to re­duce the chance I’m cherry-pick­ing.

Anyway: this meta-analy­sis an­a­lyzes 522 tri­als with 116,477 par­tic­i­pants. All 21 an­ti­de­pres­sants they stud­ied were bet­ter than placebo (a pill that con­tains no ac­tive med­i­cine). The most ef­fec­tive an­ti­de­pres­sant, Amitriptyline, had an “Odds Ratio” of 2.13, which con­verts to an ef­fect size of 0.417, which is “small-medium” ac­cord­ing to Cohen’s rec­om­men­da­tions. Or, by our school-let­ter-grade com­par­i­son: the best an­ti­de­pres­sant would take your men­tal health grade from an F to F+, or C to C+.

From Figure 3 of that pa­per, you can see that Amitriptyline has the high­est es­ti­mated ef­fect size, while the side ef­fects are no worse than placebo:

But hang on, only F to F+ on av­er­age? How does that square with peo­ple’s per­sonal ex­pe­ri­ence that an­ti­de­pres­sants have been life­sav­ing?

Well, first: the av­er­age per­son has around 1 tes­ti­cle.

The punch­line be­ing ~50% of peo­ple have 2 tes­ti­cles while ~50% of peo­ple have 0 tes­ti­cles, hence the av­er­age is “around 1”. Likewise, the av­er­age ef­fect for the best an­ti­de­pres­sant is 0.4 — but some peo­ple re­spond much bet­ter than that… and some re­spond much worse. (e.g. dif­fer­ent kinds of an­ti­de­pres­sant, dif­fer­ent kinds of de­pres­sion, dif­fer­ent kinds of peo­ple, etc. Note that this caveat also ap­plies to the Vitamin D & Omega-3 stud­ies, and all med­ical stud­ies.)

And, sec­ond: the be­lief that things will get bet­ter is a pow­er­ful thing. Unfortunately, the power of hope gets a bad name in med­i­cine: “placebo”.

When you take any med­i­cine, you don’t just get (effect of med­i­cine). You get (effect of med­i­cine + ef­fect of placebo + ef­fect of time).

The ef­fect of placebo + time: prob­a­bly around 0.9.

The ef­fect of placebo alone: Amazingly, de­spite re­searchers hav­ing used place­bos for decades, it’s only re­cently that we started test­ing “open-label” place­bos: place­bos where we just tell the pa­tient it’s a placebo. We then com­pare “getting placebo” to “getting noth­ing”. The ef­fect size of open placebo, on stuff rang­ing from pain to de­pres­sion, is around 0.43. (Spille et al 2023)

The ef­fect of time alone: Using the above two num­bers, I’d guessti­mate: 0.9 - 0.43 = 0.47. “Time” in­cludes both nat­ural heal­ing, and “regression to the mean”.

So, the in­di­vid­ual ef­fect of med­ica­tion, psy­cho­log­i­cal placebo, and time, are all around +0.4 each. And com­bined, they give you +1.20, or go­ing from F to D+ or C to B+. That’s why many peo­ple re­port an­ti­de­pres­sants be­ing life­sav­ing! (Again, on av­er­age; some peo­ple re­act much worse.)

“Wait, the im­prove­ment from an­ti­de­pres­sants is mostly placebo + time?” Yes, and this is widely known in psy­chi­a­try. I mean, they’re not yelling it from the rooftops, but it ain’t no se­cret. Decades ago, the in­fa­mous Kirsch & Sapirstein 1998 es­ti­mated that the im­prove­ment from an­ti­de­pres­sants is ~75% placebo + time. Even the most crit­i­cal re­sponse to Kirsch’s work, Fountoulakis & Möller 2011, still finds it’s mostly placebo + time.

But again, I think “placebo” is too dis­mis­sive a word for the power of hope. Hope is­n’t magic, but it’s some­thing, and mea­sur­ably so: around +0.4. I as­sert: the placebo ef­fect is­n’t a bug, it’s a fea­ture! It proves the con­nec­tion be­tween men­tal state & phys­i­cal health.

But any­way, for the rest of this ar­ti­cle, I’ll only be re­port­ing ef­fect sizes ver­sus placebo + time. Just re­mem­ber that the power of hope gives you an ex­tra +0.4 (like C to C+) for all in­ter­ven­tions.

Keep get­ting con­fused on which fat is what? Me too. So, here’s a crash course on var­i­ous fats:

Fatty acids are chains of car­bons & hy­dro­gens + two oxy­gens. They say “OOH” at one end, and “HHH” at the other end:

A sat­u­rated fatty acid is one where all the car­bons’ free spots are filled up with hy­dro­gens. (Hence, “saturated”) This makes the mol­e­cule stick straight out. This is why long sat­u­rated fatty acids — like those found in but­ter — tend to be solid at room tem­per­a­ture.

In con­trast, un­sat­u­rated fatty acids have at least one hy­dro­gen miss­ing. This causes them to have a dou­ble-bond “kink” in the mol­e­cule. This makes them not stick out, which is why un­sat­u­rated fats tend to be liq­uid at room tem­per­a­ture. Mono-unsaturated fatty acids (MUFAs) — like in olive oil — only have one kink. Poly-unsaturated fatty acids (PUFAs) — like in fatty fish — have two or more kinks. Let’s be ma­ture adults about this, please.

For com­plete­ness: trans fats are un­sat­u­rated fats whose “kink” is twisted around, caus­ing them to go straight. That is the worst sen­tence I’ve writ­ten all month. The twisted kink is caused by the hy­dro­gens be­ing on op­po­site sides, hence “trans”. (And yes, if they’re on the same side it’s “cis”. Latin was a mis­take.) The mol­e­cule be­ing straight is why trans fats — which mar­garine used to be full of — are solid at room tem­per­a­ture, de­spite be­ing an un­sat­u­rated fat.

It’s neat when­ever you can trace the his­tory of some­thing right down to its atoms! Margarine was first in­vented be­cause it’s cheaper, and is spread­able straight from the fridge, un­like but­ter. Margarine (used to be) made by tak­ing un­sat­u­rated veg­etable oils, which were cheaper than an­i­mal fats, then pump­ing a bunch of hy­dro­gens into it (hence, “hydrogenated oils”). If you com­pletely hy­dro­genate an oil, it be­comes a sat­u­rated fat. But they only par­tially hy­dro­genated those oils, lead­ing to trans fats, which were cheaper & a spread­able semi-solid at fridge tem­per­a­ture.

In the 1970s & 80s, the US Food & Drug Administration con­cluded that trans fats were not harm­ful to hu­mans, and nu­tri­tion­ists pro­moted mar­garine over but­ter, be­cause but­ter had “unhealthy” sat­u­rated fats. But in the early 1990s, sci­en­tists re­al­ized that trans fats were even worse for you than sat­u­rated fats. Only in the 2010′s, did most Western coun­tries start of­fi­cially ban­ning trans fats. Reminder: pol­icy is of­ten decades be­hind sci­ence.

I need to stop go­ing on in­fo­dump tan­gents. Anyway, Omega-3 is any fatty acid with its first kink at the 3rd car­bon from the Omega end (“HHH”), though it can have more kinks later down the chain. (And yes, Omega-6 has its first kink at the 6th car­bon, and Omega-9 has its first kink at the 9th car­bon. There’s noth­ing phys­i­cally pre­vent­ing Omega-4 or Omega-5′s from ex­ist­ing, but due to some quirk of evo­lu­tion, Omega-3, -6, and -9 are the ones bi­o­log­i­cal life uses most. As far as I can tell, there’s no spe­cific rea­son they’re all mul­ti­ples of 3. Probably just a co­in­ci­dence. There is a less com­mon Omega-7.)

Finally, there’s three main types of Omega-3: EPA (Eicosapentaenoic Acid), DHA (Docosahexaenoic Acid), and ALA (Alpha-Linolenic Acid). ALA is mostly found in plants like chia seeds & wal­nuts, while EPA & DHA mostly come from seafood, though there are al­gae-based ve­gan sources.

EPA & DHA are the fo­cus of this sec­tion. For bio-me­chan­i­cal rea­sons I don’t un­der­stand but I as­sume some­one else does: EPA is the one as­so­ci­ated with anti-in­flam­ma­tion, bet­ter brain health, and less de­pres­sion… while DHA is­n’t. (But DHA is still needed for other stuff, like your neu­rons’ cell walls, so don’t cut them out com­pletely!)

All the above info in a Venn (technically Euler) di­a­gram:

Okay, enough yap. Time for the ac­tual data:

Sublette et al 2011 is an older meta-analy­sis (15 tri­als with 916 par­tic­i­pants). It’s the only meta-analy­sis I could find that es­ti­mates the ac­tual “dose-response” curve, which shows: how much ef­fect, for how much treat­ment.

Why is dose-re­sponse im­por­tant? Because one prob­lem with many meta-analy­ses is they’ll do some­thing like: “Study 1 gave pa­tients 1 gram of med­i­cine and saw a +1 im­prove­ment in dis­ease, Study 2 gave 10 grams and saw +4 im­prove­ment, Study 3 gave 100 grams and saw neg­a­tive –5 im­prove­ment… the av­er­age of +1, +4, and –5 is zero… there­fore the med­i­cine’s ef­fect is zero.”

As men­tioned ear­lier, this is a mean­ing­less mean. That’s why we want to know the re­sponse at each dose.

Anyway, the Sublette meta-analy­sis gath­ered ran­dom­ized tri­als study­ing Omega-3 on de­pres­sion (vs placebo, of course) and got the fol­low­ing dose-re­sponse curve.⤵ Note that the hor­i­zon­tal axis is not just amount of to­tal Omega-3, but specif­i­cally the ex­tra amount of “unopposed” EPA, above the amount of DHA. Or in other words, “EPA mi­nus DHA”:

The top ef­fect size is around +0.558, which is like go­ing from an F to D–, or C to B–. You get this max­i­mum ef­fect around 1 to 2 grams of ex­tra EPA, and too much EPA gets worse re­sults. The meta-analy­sis finds that Omega-3 sup­ple­ments that are ~60% EPA (and the rest DHA) are op­ti­mal.

Is this in line with later meta-analy­ses? More or less! Liao et al 2019 also finds that ~1 gram of ≥60% EPA is best, but ac­tu­ally finds a higher ef­fect size: +1.03. Kelaiditis et al 2023 also finds 1 to 2g of ≥60% EPA is best, but found a lower ef­fect size of +0.43… which is still as good as the best an­ti­de­pres­sant! So, I’m tak­ing +0.558 as the me­dian es­ti­mate.

Let’s con­vert this to an ac­tion­able rec­om­men­da­tion: You want around 1 gram of EPA a day. So if your sup­ple­ments are 60% EPA, you need 1 gram ÷ 0.6 ~= 1.667 grams = 1667 mil­ligrams. Let’s round this down for con­ve­nience: get 1500 mg/​day of 60%-EPA Omega-3 sup­ple­ments.

In com­par­i­son, most of­fi­cial health or­ga­ni­za­tions rec­om­mend “250–500 mg com­bined EPA and DHA each day for healthy adults.” That is over three times too low, at least for op­ti­mal ef­fects on de­pres­sion. Which, as we cal­cu­lated above, is prob­a­bly around 1500 mg/​day. (The of­fi­cial safe dose is 5000 mg/​day)

Direct ef­fect on sui­cide: Finally, a (small) study di­rectly in­ves­ti­gat­ing the link be­tween sui­cide & Omega-3. Sublette et al 2006: “Low [DHA] and low Omega-3 pro­por­tions […] pre­dicted risk of sui­ci­dal be­hav­ior among de­pressed pa­tients over the 2-year pe­riod.” Though keep in mind this is a small study, and it’s ob­ser­va­tional not ex­per­i­men­tal. Also, weird that con­trary to the above stud­ies on de­pres­sion, DHA pre­dicted sui­cide but not EPA. Not sure what to make of that.

Bonus: Omega-3 may also boost cog­ni­tion? Shahinfar et al 2025: “Enhancement of global cog­ni­tive abil­i­ties was ob­served with in­creas­ing omega-3 dosage up to 1500 mg/​day. [effect size = 1.00, like go­ing from a grade of C to B!], fol­lowed by down­ward trend at higher doses.”

Ghaemi et al 2024 is a meta-analy­sis on Vitamin D on de­pres­sion (31 tri­als with 24,189 par­tic­i­pants).

Again, it ac­tu­ally es­ti­mates a dose-re­sponse curve! Below is Figure 1 + Table 2, show­ing the ef­fect of Vitamin D dosage on de­pres­sion vs placebo. The solid line is the av­er­age es­ti­mated ef­fect, dashed lines are 95% con­fi­dence in­ter­val. Note the ef­fect size is neg­a­tive in this fig­ure, be­cause they’re mea­sur­ing re­duc­tion in de­pres­sive symp­toms:

The up­per range of un­cer­tainty is low­est at 5000 IU (International Units) of Vitamin D a day, with an es­ti­mated ef­fect size of 1.82, with a 95% un­cer­tainty range, from 0.98 to 2.66. Let’s be pes­simistic, and take the low­est end: 0.98, like tak­ing your men­tal health from an F to D, or C to B.

Is this in line with ear­lier meta-analy­ses? Again, more or less! Mikola et al 2022 found a lower es­ti­mate: the ef­fect for ≥ 2000 IU/day is 0.407. Note that even this is still on par with the best an­ti­de­pres­sant! And Xie et al 2022 found a higher es­ti­mate: the ef­fect of > 2,800 IU/day is 1.23. So, I’ll take the me­dian es­ti­mate: around 0.98. (And I’m rec­om­mend­ing 4,000 IU/day, since that’s the “official” max safe dose. Though as we’ll see later, even the of­fi­cial max dose may be too low.)

Does this still work even if you’re al­ready tak­ing an­ti­de­pres­sants? Yup! Table 1 of the first meta-analy­sis, also shows that Vitamin D helps for both pa­tients us­ing an­ti­de­pres­sant med­ica­tion, and not. This is en­cour­ag­ing: it means you can stack both med­ica­tions & sup­ple­ments!

Does this still work even if you don’t have Vitamin D in­suf­fi­ciency? Yes, but ad­mit­tedly much less. That said, you prob­a­bly do have a Vitamin D in­suf­fi­ciency. Liu et al 2018 finds that a bit un­der half of American adults (41.4%) have in­suf­fi­cient Vitamin D blood lev­els. And Manios et al 2017 finds that over half of kids (52.5%) in Greece — frick­in’ sunny Greece! — are still Vitamin D in­suf­fi­cient.

Also, the “official” rec­om­men­da­tions are all too low:

So, if these three meta-analy­ses are right, then high doses — 2000 IU/day or more, pos­si­bly 4000 (official max dose) or higher — is op­ti­mal. But the of­fi­cial rec­om­men­da­tion for Vitamin D is 400–800 IU/day, sev­eral times too low.

And even the of­fi­cial max dose of 4000 IU/day may be too low! But McCullough et al 2019 gave over thou­sands of par­tic­i­pants 5,000 to 10,000 IU/day, for seven years, and there were zero cases of se­ri­ous side ef­fects. This matches later stud­ies like Billington et al 2020, a 3-year-long trial on hun­dreds of par­tic­i­pants, which found “the safety pro­file of vi­t­a­min D sup­ple­men­ta­tion is sim­i­lar for doses of 400, 4000, and 10,000 IU/day.” (Although 15 par­tic­i­pants got “mild hy­per­cal­cemia”, but “all cases re­solved on re­peat test­ing.” Either way, that’s a small cost for re­duc­ing the risk of ma­jor de­pres­sion & sui­cide.)

And it makes evo­lu­tion­ary sense that 10,000 IU a day should be safe. Your skin, ex­posed to the Sun’s ul­tra­vi­o­let rays, can syn­the­size up to (the equiv­a­lent of) 10,000 IU a day, be­fore plateau­ing out. Source is Vieth 1999: “Because vi­t­a­min D is po­ten­tially toxic, in­take of [1000 IU/day] has been avoided even though the weight of ev­i­dence shows that the cur­rently ac­cepted [limit] of [2000 IU/day] is too low by at least 5-fold.” And Papadimitriou 2017 re­views sev­eral pre­vi­ous stud­ies that find sta­tis­ti­cal er­rors be­hind of­fi­cial rec­om­men­da­tions; cor­rect­ing for these, adults should get 8000 IU/day.

So why are all the of­fi­cial sources still so para­noid about Vitamin D, and low­balling the rec­om­men­da­tions? Well, alas, of­fi­cial pol­icy is al­ways a few decades be­hind the sci­ence in any field. See: trans fats, open-la­bel place­bos, aerosol trans­mis­sion of Covid-19, etc. And be­cause some­thing some­thing in­cen­tives, it’s “rational” for gov­ern­ment/​in­sur­ers to be very risk-averse & slow to change (for bet­ter & worse).

Speaking of the Sun, why take sup­ple­ments in­stead of just get­ting Vitamin D from sun ex­po­sure? Well, skin can­cer. But also: be­cause Sun-Skin D varies greatly de­pend­ing on the sea­son, your lat­i­tude, and your skin type. There’s less ul­tra­vi­o­let rays from the Sun in win­ter/​fall, and at lat­i­tudes fur­ther from the equa­tor. And the darker your skin is, the less Vitamin D your skin makes for the same amount of Sun ex­po­sure. As ex­pected from the bio-physics of skin, Black adults have the high­est preva­lence of Vitamin D de­fi­ciency (82.1%!!), fol­lowed by Hispanic adults (62.9%). (But hey, at least Black adults have the low­est in­ci­dence of skin can­cer. You win some you lose some.) The point is: speak­ing as some­one with Southeast Asian skin, who’s cur­rently in Canada dur­ing win­ter… even if I stood out­side naked for hours, I’d get ap­prox­i­mately zero IU/day of Vitamin D from the Sun. Thus: sup­ple­ments.

Direct ef­fect on sui­cide: Finally, a meta-analy­sis di­rectly mea­sur­ing the ef­fect of Vitamin D on sui­ci­dal be­hav­iour. Yu et al 2025: “Vitamin D in pa­tients with [suicidal be­hav­iours] were sig­nif­i­cantly lower than in con­trols (standardized mean dif­fer­ence: –0.69, or a ‘medium’ dif­fer­ence)”. Reminder that this pa­per by it­self only mea­sures cor­re­la­tion, not cau­sa­tion — but com­bined with the above ex­per­i­ments of Vitamin D on de­pres­sion, I think it’s rea­son­able to guess it’s partly causal.

* Almost half of you have a Vitamin D in­suf­fi­ciency ac­cord­ing to the of­fi­cial rec­om­men­da­tion (800 IU/day).

* And those of­fi­cial rec­om­men­da­tions are way too low. The op­ti­mal amount of Vitamin D for de­pres­sion is prob­a­bly 4000 IU/day, with an ef­fect around twice that of the best an­ti­de­pres­sant.

* Even the of­fi­cial max­i­mum safe dose (4000 IU/day) is be­low what your body can pro­duce from the Sun in op­ti­mal con­di­tions (10,000 IU/day). Recent ran­dom­ized con­trolled tri­als con­firm that 10,000 IU/day is, in­deed, mostly safe.

* Reminder that of­fi­cial pol­icy is of­ten decades be­hind the sci­ence.

* Reminder that I’m not say­ing “take sup­ple­ments in­stead of an­ti­de­pres­sants”; in fact the above meta-analy­sis shows you can ef­fec­tively stack them!

Bonus: Vitamin D sup­ple­men­ta­tion was found in sev­eral ran­dom­ized con­trolled tri­als to re­duce mor­tal­ity from Covid-19, though much less than of­fi­cial treat­ments like Paxlovid. Vitamin D also prob­a­bly helps guard against in­fluenza too, though the ev­i­dence is small & early.

Scurvy is caused by a lack of Vitamin C. It’s a con­di­tion that causes your wounds to re-open up & teeth to fall out. Scurvy used to kill al­most half(!) of all sailors on ma­jor ex­pe­di­tions; it’s es­ti­mated mil­lions died. It can be cured by eat­ing lemons.

Rickets is mostly caused by a lack of Vitamin D. It’s a con­di­tion where kids’ bones go all soft and de­formed. During the Industrial Revolution, up to 80% of kids suf­fered from it. It can be pre­vented with cod liver oil.

Goiters is mostly caused by a lack of Iodine. It’s a con­di­tion where the thy­roid gland in your neck swells up painfully, to the size of an ap­ple. During WWI, a third of adult men had goi­ters. It can be pre­vented with iodized salt.

About 1 in 4 peo­ple are ex­pected to have clin­i­cal de­pres­sion some­time in their life. Depression is the #1 source of the global “burden from dis­ease” in the men­tal health cat­e­gory, and that cat­e­gory is the #6 bur­den of dis­ease in the world, above Alzheimer’s, malaria, and sex­u­ally trans­mit­ted in­fec­tions.

The ef­fec­tive al­tru­ists are all, “woah for just $3000 you can pre­vent a child’s death from malaria” — and that’s great! save them kids! — but where’s the fan­fare for the ac­cu­mu­lat­ing ev­i­dence that, “woah with cheap daily sup­ple­ments we can save mil­lions from sui­cide & de­pressed lives”?

Over and over again through­out his­tory, some hor­rific thing that caused mil­lions to suf­fer, turned out to be “yeah you were miss­ing this one mol­e­cule lol”. To be clear: not every­thing is gonna be that sim­ple, and men­tal health is not “just” chem­istry. Also, all the num­bers on this page have with large er­ror bars & un­cer­tainty, more re­search is needed.

But, as of right now, I feel I can at least con­fi­dently claim the fol­low­ing:

In iOS 26.3, Apple in­tro­duced a new pri­vacy fea­ture which lim­its “precise lo­ca­tion” data made avail­able to cel­lu­lar net­works via cell tow­ers. The fea­ture is only avail­able to de­vices with Apple’s in-house mo­dem in­tro­duced in 2025. The an­nounce­ment says

Cellular net­works can de­ter­mine your lo­ca­tion based on which cell tow­ers your de­vice con­nects to.

This is well-known. I have served on a jury where the pros­e­cu­tion ob­tained lo­ca­tion data from cell tow­ers. Since cell tow­ers are sparse (especially be­fore 5G), the ac­cu­racy is in the range of tens to hun­dreds of me­tres.

But this is not the whole truth, be­cause cel­lu­lar stan­dards have built-in pro­to­cols that make your de­vice silently send GNSS (i.e. GPS, GLONASS, Galileo, BeiDou) lo­ca­tion to the car­rier. This would have the same pre­ci­sion as what you see in your Map apps, in sin­gle-digit me­tres.

In 2G and 3G this is called Radio Resources LCS Protocol (RRLP)

So the net­work sim­ply asks “tell me your GPS co­or­di­nates if you know them” and the phone will re­spond.

In 4G and 5G this is called LTE Positioning Protocol (LPP)

RRLP, RRC, and LPP are na­tively con­trol-plane po­si­tion­ing pro­to­cols. This means that they are trans­ported in the in­ner work­ings of cel­lu­lar net­works and are prac­ti­cally in­vis­i­ble to end users.

It’s worth not­ing that GNSS lo­ca­tion is never meant to leave your de­vice. GNSS co­or­di­nates are cal­cu­lated en­tirely pas­sively, your de­vice does­n’t need to send a sin­gle bit of in­for­ma­tion. Using GNSS is like find­ing out where you are by read­ing a road sign: you don’t have to tell any­one else you read a road sign, any­one can read a road sign, and the peo­ple who put up road signs don’t know who read which road sign when.

These ca­pa­bil­i­ties are not se­crets but some­how they have mostly slid un­der the radar of the pub­lic con­scious­ness. They have been used in the wild for a long time, such as by the DEA in the US in 2006:

[T]he DEA agents pro­cured a court or­der (but not a search war­rant) to ob­tain GPS co­or­di­nates from the couri­er’s phone via a ping, or sig­nal re­quest­ing those co­or­di­nates, sent by the phone com­pany to the phone.

And by Shin Bet in Israel, which tracks every­one every­where all the time:

The GSS Tool was based on cen­tral­ized cel­lu­lar track­ing op­er­ated by Israel’s General Security Services (GSS). The tech­nol­ogy was based on a frame­work that tracks all the cel­lu­lar phones run­ning in Israel through the cel­lu­lar com­pa­nies’ data cen­ters. According to news sources, it rou­tinely col­lects in­for­ma­tion from cel­lu­lar com­pa­nies and iden­ti­fies the lo­ca­tion of all phones through cel­lu­lar an­tenna tri­an­gu­la­tion and GPS data.

Notably, the Israeli gov­ern­ment started us­ing the data for con­tact trac­ing in March 2020, only a few weeks af­ter the first Israeli COVID-19 case. An in­di­vid­ual would be sent an SMS mes­sage in­form­ing them of close con­tact with a COVID pa­tient and re­quired to quar­an­tine. This is good ev­i­dence that the lo­ca­tion data Israeli car­ri­ers are col­lect­ing are far more pre­cise than what cell tow­ers alone can achieve.

A ma­jor caveat is that I don’t know if RRLP and LPP are the ex­act tech­niques, and the only tech­niques, used by DEA, Shin Bet, and pos­si­bly oth­ers to col­lect GNSS data; there could be other pro­to­cols or back­doors we’re not privy to.

Another un­known is whether these pro­to­cols can be ex­ploited re­motely by a for­eign car­rier. Saudi Arabia has abused SS7 to spy on peo­ple in the US, but as far as I know this only lo­cates a de­vice to the cov­er­age area of a Mobile Switching Center, which is less pre­cise than cell tower data. Nonetheless, given the abysmal cul­ture, com­pe­tency, and in­tegrity in the tele­com in­dus­try, I would not be shocked if it’s pos­si­ble for a state ac­tor to ob­tain the pre­cise GNSS co­or­di­nates of any­one on earth us­ing a phone num­ber/​IMEI.

Apple made a good step in iOS 26.3 to limit at least one vec­tor of mass sur­veil­lance, en­abled by hav­ing full con­trol of the mo­dem sil­i­con and firmware. They must now al­low users to dis­able GNSS lo­ca­tion re­sponses to mo­bile car­ri­ers, and no­tify the user when such at­tempts are made to their de­vice.

When I moved to a new apart­ment with my fam­ily, the ca­ble com­pany we were used to was­n’t avail­able. We had to set­tle for Dish Network. I was­n’t too happy about mak­ing that switch, but some­thing on their web­site caught my at­ten­tion. For an ad­di­tional $5 a month, I could have ac­cess to DVR. I switched im­me­di­ately.

This was 2007. DVR was not new, but it was­n’t com­monly bun­dled with set-top boxes. TiVo was still the pop­u­lar way to record, pause, and rewind live TV. We re­ceived two set-top boxes, one for each room with a TV, and three re­motes. Two re­motes had IR (infrared) blasters and, sur­pris­ingly, one RF (radio fre­quency) re­mote.

After us­ing the RF re­mote, I won­dered: Why would any­one ever use an IR re­mote again? You did­n’t need a di­rect line of sight with the de­vice you were con­trol­ling. I could ac­tu­ally stand in the kitchen and con­trol the TV. It was amaz­ing. But with the con­ve­nience of RF came other prob­lems that IR users never had to worry about. Interference.

After sev­eral months of en­joy­ing my ser­vice, one of my neigh­bors, the loud­est in the build­ing, also switched to Dish Network. And he also got the RF re­mote. This was the type of neigh­bor who would leave the house with the TV on, vol­ume blast­ing.

One day, I was in the liv­ing room watch­ing TV when the chan­nel just flipped. I must have ac­ci­den­tally hit a but­ton, so I changed it back. But not a few sec­onds later, the chan­nel changed again. Then the vol­ume went up. I fig­ured my sis­ter must have had the RF re­mote and was mess­ing with me. But no, the re­mote was in my hand. I as­sumed some­thing was wrong with it.

The whole time I was watch­ing TV, the chan­nels kept ran­domly switch­ing. I banged the re­mote on the table a cou­ple of times, but it still switched. I re­moved the bat­ter­ies from the re­mote, it still switched. I un­plugged the de­vice for a few min­utes, plugged it back in, and… it still switched. Frustrated, I went through the de­vice set­tings and dis­abled the RF re­mote. That’s when it fi­nally stopped. I was­n’t happy with this so­lu­tion, but it al­lowed me to watch TV un­til I fig­ured some­thing out.

One evening, when every­one was asleep and the neigh­bor was watch­ing a loud TV show, I de­cided to di­ag­nose the is­sue. The mo­ment I pressed the power but­ton on the RF re­mote, my TV and set-top box turned on, and the neigh­bor’s TV went silent. “Fuck!” I heard some­one say. I was con­fused. Did I just do that? The TV turned back on, the vol­ume went up. I walked to the win­dow armed with the re­mote. I counted to three, then pressed the power but­ton. My neigh­bor’s TV went silent. He growled.

I am the cap­tain now.

Every time he turned the TV on, I pressed the power but­ton again and his de­vice went off. Well, what do you know? We had in­ter­fer­ence some­how. Our re­motes were set up to op­er­ate at the same fre­quency. Each re­mote con­trolled both de­vices.

But I’m not that kind of neigh­bor. I was­n’t go­ing to con­tinue to mess with him. Instead, I de­cided I would pay him a visit in the morn­ing and ex­plain that our re­motes are tuned to the same fre­quency. I would bring the RF re­mote with me just to show him a demo. I was go­ing to be a good neigh­bor.

In the morn­ing, I went down­stairs, re­mote in hand. I knocked on the door, and a gen­tle­man in his for­ties an­swered the door. I had re­hearsed my speech and pre­sen­ta­tion. This would be a good op­por­tu­nity to build a good rap­port, and have a shared story. Maybe he would tell me how he felt when the TV went off. How he thought there was a ghost in the house or some­thing. But that’s not what hap­pened.

“Hi, I’m Ibrahim. Your up­stairs neigh­bor…” I started and was in­ter­rupted al­most im­me­di­ately. “Whatever you are sell­ing,” he yelled. “I’m not buy­ing.” and he closed the door on my face. I knocked a sec­ond time, be­cause ob­vi­ously there was a mis­un­der­stand­ing. He never an­swered. Instead, the TV turned on and a movie played at high vol­ume. So much for my pre­pared speech.

The RF set­tings on my set-top box re­mained turned off. My fam­ily never dis­cov­ered its ben­e­fit any­way, they al­ways pointed at the box when press­ing the but­tons. It was­n’t much of an in­con­ve­nience. In fact, I later found in the man­ual that you could re­pro­gram the de­vice and re­mote to use a dif­fer­ent fre­quency. I did not re­pro­gram my re­mote. Instead, my fam­ily used the two IR re­motes, and brought the RF re­mote in my bed­room where it per­ma­nently re­mained on my night stand.

Why in the bed­room? Because I de­cided to teach my neigh­bor some good man­ners. Whenever he turned up his vol­ume, I would sim­ply turn off his de­vice. I would hear his frus­tra­tion, and his at­tempts at solv­ing the prob­lem. Like a cir­cus an­i­mal trainer, I re­mained con­sis­tent. If the vol­ume of his TV went above what I imag­ined to be 15 to 20, I would press the power but­ton. It be­came a rou­tine for me for weeks. Some nights were dif­fi­cult, I would keep the re­mote un­der my pil­low, bat­tling my stub­born neigh­bor all night.

One day, I no­ticed that I had­n’t pressed the but­ton in days. I opened the win­dow and I could still hear the faint sound of his TV. Through trial and er­ror, he learned the les­son. If the vol­ume re­mained un­der my ar­bi­trary thresh­old, the TV would re­main on. But as soon as he passed that thresh­old, the de­vice would turn off.

Sometimes, he would have com­pany and there would be noise com­ing out of his apart­ment. I used the one tool in my tool box to send him a mes­sage. Turn off the TV. All of the sud­den, my neigh­bor and his guest will be re­minded of the un­spo­ken rules, and be­come mind­ful of their neigh­bors.

Maybe some­where on the web, in some ob­scure fo­rum, some­one asked the ques­tion: “Why does my set-top box turn off when I in­crease the vol­ume?” Well, it might be 18 years too late, but there’s your an­swer. There is a man out there who re­li­giously sets his vol­ume to 18. He does­n’t quite know why. That’s Pavlovian con­di­tion­ing at its best.

Musings

That’s right — this lit­tle de­vice is what stood be­tween me and the abil­ity to run an even older piece of soft­ware that I re­cently un­earthed dur­ing an ex­pe­di­tion of soft­ware ar­chae­ol­ogy.

For a bit more back­ground, I was re­cently in­volved in help­ing a friend’s ac­count­ing firm to move away from us­ing an ex­tremely legacy soft­ware pack­age that they had locked them­selves into us­ing for the last four decades.

This soft­ware was built us­ing a pro­gram­ming lan­guage called RPG (“Report Program Generator”), which is older than COBOL (!), and was used with IBM’s midrange com­put­ers such as the System/3, System/32, and all the way up to the AS/400. Apparently, RPG was sub­se­quently ported to MS-DOS, so that the same soft­ware tools built with RPG could run on per­sonal com­put­ers, which is how we ended up here.

This ac­count­ing firm was ac­tu­ally us­ing a Windows 98 com­puter (yep, in 2026), and run­ning the RPG soft­ware in­side a DOS con­sole win­dow. And it turned out that, in or­der to run this soft­ware, it re­quires a spe­cial hard­ware copy-pro­tec­tion don­gle to be at­tached to the com­put­er’s par­al­lel port! This was a rel­a­tively com­mon prac­tice in those days, par­tic­u­larly with “enterprise” soft­ware ven­dors who wanted to pro­tect their very im­por­tant™ soft­ware from unau­tho­rized use.

Sadly, most of the text and mark­ings on the don­gle’s la­bel has been worn or scratched off, but we can make out sev­eral clues:

The words “Stamford, CT”, and what’s very likely the logo of a com­pany called “Software Security Inc”. The only ev­i­dence for the ex­is­tence of this com­pany is this record of them ex­hibit­ing their wares at SIGGRAPH con­fer­ences in the early 1990s, as well as sev­eral patents is­sued to them, re­lat­ing to soft­ware pro­tec­tion.

A word that seems to say “RUNTIME”, which will be­come clear in a bit.

My first course of ac­tion was to take a disk im­age of the Windows 98 PC that was run­ning this soft­ware, and get it run­ning in an em­u­la­tor, so that we could see what the soft­ware ac­tu­ally does, and per­haps ex­port the data from this soft­ware into a more mod­ern for­mat, to be used with mod­ern ac­count­ing tools. But of course all of this re­quires the hard­ware don­gle; none of the ac­count­ing tools seem to work with­out it plugged in.

Before do­ing any­thing, I looked through the disk im­age for any ad­di­tional in­ter­est­ing clues, and found plenty of fas­ci­nat­ing (and ar­chae­o­log­i­cally sig­nif­i­cant?) stuff:

We’ve got a com­piler for the RPG II lan­guage (excellent!), made by a com­pany called Software West Inc.

Even bet­ter, there are two ver­sions of the RPG II com­piler, re­leased on var­i­ous dates in the 1990s by Software West.

We’ve got the com­plete source code of the ac­count­ing soft­ware, writ­ten in RPG. It looks like the full ac­count­ing pack­age con­sists of nu­mer­ous RPG mod­ules, with a gnarly com­bi­na­tion of DOS batch files for or­ches­trat­ing them, all set up as a “menu” sys­tem for the user to nav­i­gate us­ing num­ber com­bi­na­tions. Clearly the au­thor of this ac­count­ing sys­tem was orig­i­nally an IBM main­frame pro­gram­mer, and in­sisted on bring­ing those skills over to DOS, with mixed re­sults.

I be­gan by play­ing around with the RPG com­piler in iso­la­tion, and I learned very quickly that it’s the RPG com­piler it­self that re­quires the hard­ware don­gle, and then the com­piler au­to­mat­i­cally in­jects the same copy-pro­tec­tion logic into any ex­e­cuta­bles it gen­er­ates. This ex­plains the text that seems to say “RUNTIME” on the don­gle.

The com­piler con­sists of a few ex­e­cutable files, no­tably RPGC. EXE, which is the com­piler, and SEU.EXE, which is a source ed­i­tor (“Source Entry Utility”). Here’s what we get when we launch SEU with­out the don­gle, af­ter a cou­ple of sec­onds:

A bit rude, but this gives us an im­por­tant clue: this pro­gram must be try­ing to com­mu­ni­cate over the par­al­lel port over the course of a few sec­onds (which could give us an op­por­tu­nity to pause it for de­bug­ging, and see what it’s do­ing dur­ing that time), and then ex­its with a mes­sage (which we can now find in a dis­as­sem­bly of the pro­gram, and trace how it gets there).

A great tool for dis­as­sem­bling ex­e­cuta­bles of this vin­tage is Reko. It un­der­stands 16-bit real mode ex­e­cuta­bles, and even at­tempts to de­com­pile them into read­able C code that cor­re­sponds to the dis­as­sem­bly.

And so, look­ing at the de­com­piled/​dis­as­sem­bled code in Reko, I ex­pected to find in and out in­struc­tions, which would be the tell­tale sign of the pro­gram try­ing to com­mu­ni­cate with the par­al­lel port through the PC’s I/O ports. However… I did­n’t see an in or out in­struc­tion any­where! But then I no­ticed some­thing: Reko dis­as­sem­bled the ex­e­cutable into two “segments”: 0800 and 0809, and I was only look­ing at seg­ment 0809.

If we look at seg­ment 0800, we see the smok­ing gun: in and out in­struc­tions, mean­ing that the copy-pro­tec­tion rou­tine is def­i­nitely here, and best of all, the en­tire code seg­ment is a mere 0x90 bytes, which sug­gests that the en­tire rou­tine should be pretty easy to un­ravel and un­der­stand. For some rea­son, Reko was not able to de­com­pile this code into a C rep­re­sen­ta­tion, but it still pro­duced a dis­as­sem­bly, which will work just fine for our pur­poses. Maybe this was a prim­i­tive form of ob­fus­ca­tion from those early days, which is now con­fus­ing Reko and pre­vent­ing it from as­so­ci­at­ing this chunk of code with the rest of the pro­gram… who knows.

Here is a GitHub Gist with the dis­as­sem­bly of this code, along with my an­no­ta­tions and notes. My x86 as­sem­bly knowl­edge is a lit­tle rusty, but here is the gist of what this code does:

It’s def­i­nitely a sin­gle self-con­tained rou­tine, in­tended to be called us­ing a “far” CALL in­struc­tion, since it re­turns with a RETF in­struc­tion.

It be­gins by de­tect­ing the ad­dress of the par­al­lel port, by read­ing the BIOS data area. If the com­puter has more than one par­al­lel port, the don­gle must be con­nected to the first par­al­lel port (LPT1).

It per­forms a loop where it writes val­ues to the data reg­is­ter of the par­al­lel port, and then reads the sta­tus reg­is­ter, and ac­cu­mu­lates re­sponses in the BH and BL reg­is­ters.

At the end of the rou­tine, the “result” of the whole pro­ce­dure is stored in the BX reg­is­ter (BH and BL to­gether), which will pre­sum­ably be “verified” by the caller of the rou­tine.

Very im­por­tantly, there does­n’t seem to be any “input” into this rou­tine. It does­n’t pop any­thing from the stack, nor does it care about any reg­is­ter val­ues passed into it. Which can only mean that the re­sult of this rou­tine is com­pletely con­stant! No mat­ter what com­pli­cated back-and-forth it does with the don­gle, the re­sult of this rou­tine should al­ways be the same.

With the knowl­edge that this rou­tine must exit with some magic value stored in BX, we can now patch the first few bytes of the rou­tine to do just that! Not yet know­ing which value to put in BX, let’s start with 1234:

BB 34 12 MOV BX, 1234h

CB RETF

Only the first four bytes need patch­ing — set BX to our de­sired value, and get out of there (RETF). Running the patched ex­e­cutable with these new bytes still fails (expectedly) with the same mes­sage of “No don­gle, no edit”, but it fails im­me­di­ately, in­stead of af­ter sev­eral sec­onds of talk­ing to the par­al­lel port. Progress!

Stepping through the dis­as­sem­bly more closely, we get an­other ma­jor clue: The only value that BH can be at the end of the rou­tine is 76h (this is hard-coded into the rou­tine). So, our to­tal value for the magic num­ber in BX must be of the form 76xx. In other words, only the BL value re­mains un­known:

BB __ 76 MOV BX, 76__h

CB RETF

Since BL is an 8-bit reg­is­ter, it can only have 256 pos­si­ble val­ues. And what do we do when we have 256 com­bi­na­tions to try? Brute force it! I whipped up a script that plugs a value into that par­tic­u­lar byte (from 0 to 255) and pro­gram­mat­i­cally launches the ex­e­cutable in DosBox, and ob­serves the out­put. Lo and be­hold, it worked! The brute forc­ing did­n’t take long at all, be­cause the cor­rect num­ber turned out to be… 6. Meaning that the to­tal magic num­ber in BX should be 7606h:

BB 06 76 MOV BX, 7606h

CB RETF

Bingo!

And then, pro­ceed­ing to ex­am­ine the other ex­e­cutable files in the com­piler suite, the par­al­lel port rou­tine turns out to be ex­actly the same. All of the ex­e­cuta­bles have the ex­act same copy pro­tec­tion logic, as if it was rub­ber-stamped onto them. In fact, when the com­piler (RPGC.EXE) com­piles some RPG source code, it seems to copy the par­al­lel port rou­tine from it­self into the com­piled pro­gram. That’s right: the patched ver­sion of the com­piler will pro­duce ex­e­cuta­bles with the same patched copy pro­tec­tion rou­tine! Very con­ve­nient.

I must say, this copy pro­tec­tion mech­a­nism seems a bit… sim­plis­tic? A hard­ware don­gle that just passes back a con­stant num­ber? Defeatable with a four-byte patch? Is this re­ally wor­thy of a patent? But who am I to pass judg­ment. It’s pos­si­ble that I haven’t fully un­der­stood the logic, and the copy pro­tec­tion will some­how re-sur­face in an­other way. It’s also pos­si­ble that the cre­ators of the RPG com­piler (Software West, Inc) did­n’t take proper ad­van­tage of the hard­ware don­gle, and used it in a way that is so eas­ily by­passed.

In any case, Software West’s RPG II com­piler is now free from the con­straint of the par­al­lel port don­gle! And at some point soon, I’ll work on purg­ing any PII from the com­piler di­rec­to­ries, and make this com­piler avail­able as an ar­ti­fact of com­put­ing his­tory. It does­n’t seem to be avail­able any­where else on the web. If any­one read­ing this was as­so­ci­ated with Software West Inc, feel free to get in touch — I have many ques­tions!
