Ask just about any­body, and they’ll tell you that new cars are too ex­pen­sive. In the wake of tar­iffs shak­ing the auto in­dus­try and with the Trump ad­min­is­tra­tion pledg­ing to kill the fed­eral EV in­cen­tive, that sit­u­a­tion is­n’t look­ing to get bet­ter soon, es­pe­cially for any­one want­ing some­thing bat­tery-pow­ered. Changing that overly spendy sta­tus quo is go­ing to take some­thing rad­i­cal, and it’s hard to get more rad­i­cal than what Slate Auto has planned.

Meet the Slate Truck, a sub-$20,000 (after fed­eral in­cen­tives) elec­tric ve­hi­cle that en­ters pro­duc­tion next year. It only seats two yet has a bed big enough to hold a sheet of ply­wood. It only does 150 miles on a charge, only comes in gray, and the only way to lis­ten to mu­sic while dri­ving is if you bring along your phone and a Bluetooth speaker. It is the bare min­i­mum of what a mod­ern car can be, and yet it’s taken three years of de­vel­op­ment to get to this point.

But this is more than bar­gain-base­ment mo­tor­ing. Slate is pre­sent­ing its truck as min­i­mal­ist de­sign with DIY pur­pose, an at­tempt to not just go cheap but to cre­ate a new cat­e­gory of ve­hi­cle with a huge fo­cus on per­son­al­iza­tion. That de­sign also en­ables a low-cost ap­proach to man­u­fac­tur­ing that has caught the eye of ma­jor in­vestors, re­port­edly in­clud­ing Jeff Bezos. It’s been en­gi­neered and will be man­u­fac­tured in America, but is this ex­treme sim­pli­fi­ca­tion too much for American con­sumers?

Instead of steel or alu­minum, the Slate Truck’s body pan­els are molded of plas­tic. Or, as Slate calls them, “injection molded polypropy­lene com­pos­ite ma­te­r­ial.” The the­ory is that this makes them more durable and scratch-re­sis­tant, if only be­cause the lack of paint means they’re one color all the way through. Auto en­thu­si­asts of a cer­tain age will re­mem­ber the same ap­proach used by the now-de­funct Saturn Corporation, a man­u­fac­tur­ing tech­nique that never caught on across the in­dus­try.

While most buy­ers will rightly fix­ate on the cost of the truck, the big­ger story here might just be this rad­i­cally sim­pli­fied ap­proach to man­u­fac­tur­ing. “From the very be­gin­ning, our busi­ness model has been such that we reach cash flow pos­i­tiv­ity very shortly af­ter start of pro­duc­tion. And so from an in­vest­ment stand­point, we are far less cash-re­liant than any other EV startup that has ever ex­isted, as far as I know,” Snyder says.

MILWAUKEE (AP) — The FBI on Friday ar­rested a Milwaukee judge ac­cused of help­ing a man evade im­mi­gra­tion au­thor­i­ties, es­ca­lat­ing a clash be­tween the Trump ad­min­is­tra­tion and lo­cal au­thor­i­ties over the Republican pres­i­den­t’s sweep­ing im­mi­gra­tion crack­down.

Milwaukee County Circuit Court Judge Hannah Dugan is ac­cused of es­cort­ing the man and his lawyer out of her court­room through the jury door last week af­ter learn­ing that im­mi­gra­tion au­thor­i­ties were seek­ing his ar­rest. The man was taken into cus­tody out­side the cour­t­house af­ter agents chased him on foot.

President Donald Trump’s ad­min­is­tra­tion has ac­cused state and lo­cal of­fi­cials of in­ter­fer­ing with his im­mi­gra­tion en­force­ment pri­or­i­ties. The ar­rest also comes amid a grow­ing bat­tle be­tween the ad­min­is­tra­tion and the fed­eral ju­di­ciary over the pres­i­den­t’s ex­ec­u­tive ac­tions over de­por­ta­tions and other mat­ters.

Dugan was taken into cus­tody by the FBI on Friday morn­ing on the cour­t­house grounds, ac­cord­ing to U. S. Marshals Service spokesper­son Brady McCarron. She ap­peared briefly in fed­eral court in Milwaukee later Friday be­fore be­ing re­leased from cus­tody. She faces charges of “concealing an in­di­vid­ual to pre­vent his dis­cov­ery and ar­rest” and ob­struct­ing or im­ped­ing a pro­ceed­ing.

“Judge Dugan whole­heart­edly re­grets and protests her ar­rest. It was not made in the in­ter­est of pub­lic safety,” her at­tor­ney, Craig Mastantuono, said dur­ing the hear­ing. He de­clined to com­ment to an Associated Press re­porter fol­low­ing her court ap­pear­ance.

Democratic Wisconsin Gov. Tony Evers, in a state­ment on the ar­rest, ac­cused the Trump ad­min­is­tra­tion of re­peat­edly us­ing “dangerous rhetoric to at­tack and at­tempt to un­der­mine our ju­di­ciary at every level.”

“I will con­tinue to put my faith in our jus­tice sys­tem as this sit­u­a­tion plays out in the court of law,” he said.

Court pa­pers sug­gest Dugan was alerted to the pres­ence of U. S. Immigration and Customs Enforcement agents in the cour­t­house by her clerk, who was in­formed by an at­tor­ney that they ap­peared to be in the hall­way.

The FBI af­fi­davit de­scribes Dugan as “visibly an­gry” over the ar­rival of im­mi­gra­tion agents in the cour­t­house and says that she pro­nounced the sit­u­a­tion “absurd” be­fore leav­ing the bench and re­treat­ing to her cham­bers. It says she and an­other judge later ap­proached mem­bers of the ar­rest team in­side the cour­t­house, dis­play­ing what wit­nesses de­scribed as a “confrontational, an­gry de­meanor.”

After a back-and-forth with of­fi­cers over the war­rant for the man, Eduardo Flores-Ruiz, she de­manded that the ar­rest team speak with the chief judge and led them away from the court­room, the af­fi­davit says.

After di­rect­ing the ar­rest team to the chief judge’s of­fice, in­ves­ti­ga­tors say, Dugan re­turned to the court­room and was heard say­ing words to the ef­fect of “wait, come with me” be­fore ush­er­ing Flores-Ruiz and his lawyer through a jury door into a non-pub­lic area of the cour­t­house. The ac­tion was un­usual, the af­fi­davit says, be­cause “only deputies, ju­ries, court staff, and in-cus­tody de­fen­dants be­ing es­corted by deputies used the back jury door. Defense at­tor­neys and de­fen­dants who were not in cus­tody never used the jury door.”

A sign that re­mained posted on Dugan’s court­room door Friday ad­vised that if any at­tor­ney or other court of­fi­cial “knows or be­lieves that a per­son feels un­safe com­ing to the cour­t­house to court­room 615,” they should no­tify the clerk and re­quest an ap­pear­ance via Zoom.

Flores-Ruiz, 30, was in Dugan’s court for a hear­ing af­ter be­ing charged with three counts of mis­de­meanor do­mes­tic bat­tery. Confronted by a room­mate for play­ing loud mu­sic on March 12, Flores-Ruiz al­legedly fought with him in the kitchen and struck a woman who tried to break them up, ac­cord­ing to the po­lice af­fi­davit in the case.

Another woman who tried to break up the fight and called po­lice al­legedly got el­bowed in the arm by Flores-Ruiz.

Flores-Ruiz faces up to nine months in prison and a $10,000 fine on each count if con­victed. His pub­lic de­fender, Alexander Kostal, did not im­me­di­ately re­turn a phone mes­sage Friday seek­ing com­ment.

A fed­eral judge, the same one Dugan would ap­pear be­fore a day later, had or­dered Thursday that Flores-Ruiz re­main jailed pend­ing trial. Flores-Ruiz had been in the U. S. since reen­ter­ing the coun­try af­ter he was de­ported in 2013, ac­cord­ing to court doc­u­ments.

Attorney General Pam Bondi said vic­tims were sit­ting in the court­room with state pros­e­cu­tors when the judge helped him es­cape im­mi­gra­tion ar­rest.

“The rule of law is very sim­ple,” she said in a video posted on X. “It does­n’t mat­ter what line of work you’re in. If you break the law, we will fol­low the facts and we will pros­e­cute you.”

White House of­fi­cials echoed the sen­ti­ment of no one be­ing above the law.

Sen. Tammy Baldwin, a Democrat who rep­re­sents Wisconsin, called the ar­rest of a sit­ting judge a “gravely se­ri­ous and dras­tic move” that “threatens to breach” the sep­a­ra­tion of power be­tween the ex­ec­u­tive and ju­di­cial branches.

Emilio De Torre, ex­ec­u­tive di­rec­tor of Milwaukee Turners, said dur­ing a protest Friday af­ter­noon out­side the fed­eral cour­t­house that Dugan was a for­mer board mem­ber for the lo­cal civic group who “was cer­tainly try­ing to make sure that due process is not dis­rupted and that the sanc­tity of the courts is up­held.”

“Sending armed FBI and ICE agents into build­ings like this will in­tim­i­date in­di­vid­u­als show­ing up to court to pay fines, to deal with what­ever court pro­ceed­ings they may have,” De Torre added.

The case is sim­i­lar to one brought dur­ing the first Trump ad­min­is­tra­tion against a Massachusetts judge, who was ac­cused of help­ing a man sneak out a back door of a cour­t­house to evade a wait­ing im­mi­gra­tion en­force­ment agent.

That pros­e­cu­tion sparked out­rage from many in the le­gal com­mu­nity, who slammed the case as po­lit­i­cally mo­ti­vated. Prosecutors dropped the case against Newton District Judge Shelley Joseph in 2022 un­der the Democratic Biden ad­min­is­tra­tion af­ter she agreed to re­fer her­self to a state agency that in­ves­ti­gates al­le­ga­tions of mis­con­duct by mem­bers of the bench.

The Justice Department had pre­vi­ously sig­naled that it was go­ing to crack down on lo­cal of­fi­cials who thwart fed­eral im­mi­gra­tion ef­forts.

The de­part­ment in January or­dered pros­e­cu­tors to in­ves­ti­gate for po­ten­tial crim­i­nal charges any state and lo­cal of­fi­cials who ob­struct or im­pede fed­eral func­tions. As po­ten­tial av­enues for pros­e­cu­tion, a memo cited a con­spir­acy of­fense as well as a law pro­hibit­ing the har­bor­ing of peo­ple in the coun­try il­le­gally.

Dugan was elected in 2016 to the county court Branch 31. She also has served in the court’s pro­bate and civil di­vi­sions, ac­cord­ing to her ju­di­cial can­di­date bi­og­ra­phy.

Before be­ing elected to pub­lic of­fice, Dugan prac­ticed at Legal Action of Wisconsin and the Legal Aid Society. She grad­u­ated from the University of Wisconsin-Madison in 1981 with a bach­e­lor of arts de­gree and earned her Juris Doctorate in 1987 from the school.

I was work­ing on a tech­ni­cal post about DNS res­o­lu­tion when I en­coun­tered some­thing un­ex­pected. Every time I typed the path to the hosts file (/etc/h*sts - in­ten­tion­ally ob­fus­cated to avoid trig­ger­ing the very is­sue I’m dis­cussing), my Substack ed­i­tor would dis­play a “Network Error” and fail to au­tosave my draft.

At first, I as­sumed Substack was ex­pe­ri­enc­ing an out­age. However, their sta­tus page showed all sys­tems op­er­a­tional. Something else was hap­pen­ing.

I no­ticed this er­ror ap­peared con­sis­tently when I typed that spe­cific file path. But when I wrote vari­a­tions like /etc/h0sts or /etchosts, the ed­i­tor worked fine. Curious about this pat­tern, I tested more sys­tem paths:

Path Result

/etc/h*sts ❌ Error

/etc/h0sts ✅ Works

/etchosts ✅ Works

/etc/pass*d ❌ Error

/etc/password ✅ Works

/etc/ssh/sshd_conf*g ❌ Error

/etc/ssh ✅ Works

/etc/h*sts.allowed ❌ Error

/etc/h*sts.foo ❌ Error

A pat­tern emerged: paths to com­mon Linux sys­tem con­fig­u­ra­tion files were trig­ger­ing er­rors, while slight vari­a­tions sailed through.

Looking at the browser’s de­vel­oper tools re­vealed some­thing in­ter­est­ing:

The ed­i­tor was mak­ing PUT re­quests to Substack’s API to save the draft, but when the con­tent con­tained cer­tain sys­tem paths, the re­quest re­ceived a 403 Forbidden re­sponse.

The re­sponse head­ers showed that Cloudflare was in­volved:

Server: cloud­flare

Cf-Ray: 935d70ff6864bcf5-ATL

This be­hav­ior points to what’s likely a Web Application Firewall (WAF) in ac­tion. But what’s a WAF, and why would it block these paths?

Think of a Web Application Firewall as a se­cu­rity guard for web­sites. It sits be­tween users and the web ap­pli­ca­tion, ex­am­in­ing all traf­fic and block­ing any­thing sus­pi­cious.

Like a night­club bouncer who has a list of trou­ble­mak­ers to watch for, a WAF has rules about what kinds of re­quests look dan­ger­ous. When it spots some­thing on its “suspicious list,” it re­jects the re­quest.

One com­mon at­tack that WAFs de­fend against is called a “path tra­ver­sal” at­tack. Here’s a sim­ple ex­pla­na­tion:

Imagine your web­site has files or­ga­nized in fold­ers, like:

/images/profile.jpg

/docs/report.pdf

A hacker might try to “break out” of these fold­ers by send­ing re­quests like:

/images/../../../etc/pass*d

This is an at­tempt to nav­i­gate up through di­rec­tory lev­els to ac­cess sen­si­tive sys­tem files like the pass­word file on the server.

System paths like /etc/h*sts and /etc/pass*d are com­mon tar­gets in these at­tacks be­cause they con­tain valu­able sys­tem in­for­ma­tion. A hacker who gains ac­cess to these files might find user­names, pass­word hashes, or net­work con­fig­u­ra­tions that help them com­pro­mise the sys­tem fur­ther.

[For more in­for­ma­tion on path tra­ver­sal at­tacks, check out OWASP’s guide]

Another at­tack vec­tor is “command in­jec­tion,” where an at­tacker tries to trick a web ap­pli­ca­tion into ex­e­cut­ing sys­tem com­mands. Mentioning sys­tem paths like /etc/h*sts might trig­ger fil­ters de­signed to pre­vent com­mand in­jec­tion at­tempts.

In a com­mand in­jec­tion at­tack, an at­tacker might in­put some­thing like:

; cat /etc/pass*d

If the web ap­pli­ca­tion does­n’t prop­erly san­i­tize this in­put be­fore us­ing it in a sys­tem com­mand, it could ex­e­cute the at­tack­er’s code and re­veal sen­si­tive in­for­ma­tion.

[Learn more about com­mand in­jec­tion at PortSwigger’s Web Security Academy]

Curious if oth­ers had en­coun­tered this is­sue, I searched for Substack posts con­tain­ing these sys­tem paths. Interestingly, I found a post from March 4, 2025, that suc­cess­fully in­cluded the string /etc/h*sts.allowed.

Another post from March 30, 2025, used the cu­ri­ous for­mu­la­tion etc -> hosts - per­haps a workaround for this same is­sue?

This sug­gests the fil­ter­ing be­hav­ior might have been im­ple­mented or mod­i­fied some­time be­tween these dates.

This case high­lights an in­ter­est­ing ten­sion in web se­cu­rity: the bal­ance be­tween pro­tec­tion and us­abil­ity.

Substack’s fil­ter is well-in­ten­tioned - pro­tect­ing their plat­form from po­ten­tial at­tacks. But for tech­ni­cal writ­ers dis­cussing sys­tem con­fig­u­ra­tions, it cre­ates a frus­trat­ing ob­sta­cle.

The im­ple­men­ta­tion also leaves room for im­prove­ment:

There’s no clear workaround for writ­ers dis­cussing these top­ics

The re­quest to https://​scale­with­lee.sub­stack.com/​api/​v1/​drafts/​162118646 fails with:

What’s par­tic­u­larly telling is that this is hap­pen­ing at the API level, not just in the ed­i­tor UI.

How could Substack im­prove this sit­u­a­tion for tech­ni­cal writ­ers?

Contextual fil­ter­ing: Recognize when sys­tem paths ap­pear in code blocks or tech­ni­cal dis­cus­sion­sClear er­ror mes­sages: Replace “Network Error” with some­thing like “This con­tent con­tains pat­terns that may be flagged by our se­cu­rity fil­ters”Doc­u­mented workarounds: Provide guid­ance for tech­ni­cal writ­ers on how to dis­cuss sen­si­tive paths

This quirk in Substack’s ed­i­tor re­veals the com­plex chal­lenges of build­ing se­cure plat­forms that also serve tech­ni­cal writ­ers. What looks like an at­tack pat­tern to a se­cu­rity fil­ter might be le­git­i­mate con­tent to an au­thor writ­ing about sys­tem ad­min­is­tra­tion or DevOps.

As a DevOps en­gi­neer, I find these edge cases fas­ci­nat­ing - they high­light how se­cu­rity mea­sures can some­times have un­in­tended con­se­quences for le­git­i­mate use cases.

For now, I’ll con­tinue us­ing workarounds like “/etc/h*sts” (with quotes) or al­ter­na­tive spellings when dis­cussing sys­tem paths in my Substack posts. And per­haps this ex­plo­ration will help other tech­ni­cal writ­ers un­der­stand what’s hap­pen­ing when they en­counter sim­i­lar mys­te­ri­ous “Network Errors” in their writ­ing.

Have you en­coun­tered sim­i­lar fil­ter­ing is­sues on other plat­forms? I’d love to hear about your ex­pe­ri­ences in the com­ments!

Tina on the trans­for­ma­tive power of en­thu­si­asm

When I was eight, I made a big, hand-drawn poster that said, “Do you want to join my fan club?” and put it up in the small Swiss town where I grew up.

Neighbors would ask me, “What are we go­ing to be fans of?” and I’d say, “It does­n’t mat­ter—it’s just about be­ing ex­cited.” Eight year old Tina.

Decades later, I’m still con­vinced that be­ing a fan is a state of mind.

Being a fan is all about bring­ing the en­thu­si­asm. It’s be­ing a cham­pion of pos­si­bil­ity. It’s be­liev­ing in some­one. And it’s con­ta­gious. When you’re around some­one who is su­per ex­cited about some­thing, it washes over you. It feels good. You can’t help but want to bring the en­thu­si­asm, too.

This, to me, is the real trans­for­ma­tion. Confidence is im­pres­sive, but en­thu­si­asm can change peo­ple’s lives.

If I trace all the defin­ing mo­ments of my life back to their be­gin­nings, I can al­ways find a per­son with this fan state of mind: some­one who be­lieved in me, opened a door, or il­lu­mi­nated a new path just by be­ing who they are.

This is a love let­ter to all the peo­ple who be­lieve in us and nudge us in new di­rec­tions with their en­thu­si­asm.

To the per­son who showed me you can live life your way—my beloved, ec­cen­tric Aunt Hugi

She was the most cre­ative, unique, stub­born, wild Swiss woman I have ever known. I grew up in the Swiss coun­try­side and vis­it­ing Hugi in Zurich was al­ways an ad­ven­ture. She was a fash­ion de­signer, artist, and a true orig­i­nal. As I got older, I re­ally started to ap­pre­ci­ate how she did­n’t care what peo­ple thought. She lived a coura­geous, cre­ative life and in­spired me to be bold, forge my own path, and break rules.

To the per­son who opened up a dif­fer­ent fu­ture—my first boss, Matthew Waldman

After I earned my graphic de­sign de­gree, I con­vinced my par­ents that I wanted to go to New York to find a three-month in­tern­ship. I ar­rived on a Monday night and had an in­ter­view lined up the next morn­ing with Matthew Waldman—the CEO of a small, now de­funct de­sign stu­dio. Within five min­utes of talk­ing to me, he of­fered me a job and pre­dicted that I would never leave New York.

Not only was he right, but his in­stant be­lief in me taught me that your boss can be en­thu­si­as­tic, kind, and car­ing. This set the tone go­ing for­ward—I would not ac­cept any­thing other than a lov­ing work en­vi­ron­ment.

To the per­son who nudged me to ask my­self, “What am I wait­ing for?”—my daugh­ter Ella

While work­ing as a Design Director at a dig­i­tal agency and preg­nant with my daugh­ter Ella, I found my­self in­spired to think big­ger. I al­ways wanted to run my own de­sign stu­dio and an ur­gency sud­denly hit me—I was mak­ing a hu­man, and I wanted to be a role model to them, so what was I wait­ing for? I started my own de­sign stu­dio the day she was born.

To the per­son who helped me re­alise “I can do this too”—the in­spir­ing Jim Coudal

My blog swiss­miss be­came quite pop­u­lar, but when I had other ideas, I’d sec­ond-guess them. I’d think, Who am I to do this thing? A real epiphany came when I was watch­ing Jim Coudal at SXSW. As he was de­scrib­ing his fun side pro­jects, in­clud­ing The Deck Network, Layer Tennis, and Field Notes, I re­al­ized I could put my ideas into the world, too. Seeing some­one cre­ate the things they want to cre­ate can give us per­mis­sion to do the same.

So I did it. I knew in­tu­itively that the peo­ple you sur­round your­self with change what you dream about, which led me to start the cowork­ing space Studiomates (now known as Friends Work Here). It has been mag­i­cal to see what un­folds when you gather cre­ative, kind, dri­ven hu­mans in a phys­i­cal space. We of­ten find our­selves in deep, en­gag­ing con­ver­sa­tions over cof­fee or lunch, which in turn has led to the found­ing of mul­ti­ple com­pa­nies, mag­a­zines and con­fer­ences. We be­lieve in each other, and we make each other brave.

To the per­son who en­cour­aged the mo­men­tum of CreativeMornings—co-founder of Mailchimp, Ben Chestnut

After ex­pe­ri­enc­ing the power of my cowork­ing com­mu­nity, I felt in­spired to share the magic. I was in a city of eight mil­lion peo­ple, but the cre­ative com­mu­ni­ties felt frag­mented and dis­con­nected. I knew there had to be more heart-cen­tered, cre­ative peo­ple look­ing to con­nect. So, I de­cided to in­vite peo­ple to the space for a free break­fast and a talk. I vividly re­mem­ber be­ing made fun of for invit­ing peo­ple to an event at 8:30 a.m., and as­sum­ing no one would show up. I am proud to say we had 50 at­ten­dees at the first ever CreativeMornings in October of 2008.

Just four months and four events later, I re­ceived an email from Ben Chestnut, co-founder of Mailchimp, say­ing he and his team were big fans and he won­dered if they could spon­sor fu­ture events. I had never dealt with spon­sors be­fore and clum­sily in­vited them to pay for break­fast, which turned into the most sup­port­ive and en­cour­ag­ing 15-year cor­po­rate part­ner­ship and friend­ship.

Mailchimp con­sis­tently re­minded us to fo­cus on what we do best: serv­ing and grow­ing our com­mu­nity. Having more peo­ple say, “We just want to make sure you can do your magic,” is what the world needs.

To the per­son who helped CreativeMornings think big­ger and bolder—Ruth Ann Harnisch

When I first met Ruth Ann, a for­mer jour­nal­ist and the vi­sion­ary phil­an­thropist lead­ing the Harnisch Foundation, she told me she be­lieved in CreativeMornings’ po­ten­tial to change the world, one friend­ship at a time. In an act of rad­i­cal gen­eros­ity, she pledged $1 mil­lion and be­came our first ever pa­tron—the ul­ti­mate fan!

Her sup­port is­n’t just fi­nan­cial—it’s a re­flec­tion of her deep be­lief in peo­ple and their po­ten­tial.

With her do­na­tion, we’ve been able to pi­lot Clubs: in­ti­mate, com­mu­nity-led gath­er­ings built around a shared pas­sion. In just one year, NYC Clubs brought to­gether 6,000 at­ten­dees, fur­ther pro­pelling the CreativeMornings friend­ship-en­gine.

To all the peo­ple who trans­form our lives

Every time I meet some­one with a fan state of mind, I am trans­formed—my lim­it­ing be­liefs are chal­lenged, and pos­si­bil­i­ties are ex­panded.

If one per­son can change the tra­jec­tory of my own life, imag­ine what en­tire com­mu­ni­ties can do?

I be­lieve heart-cen­tered com­mu­ni­ties can cre­ate a cul­tural shift to­wards gen­eros­ity, kind­ness, and cu­rios­ity.

A cen­tral agree­ment for CreativeMornings is: “I be­lieve in you, you be­lieve in me.” We cel­e­brate with each other. That kind of mu­tual up­lift changes you—it helps you step into your po­ten­tial and work to­wards a bet­ter fu­ture.

Music AI Sandbox, now with new fea­tures and broader ac­cess

Google has long col­lab­o­rated with mu­si­cians, pro­duc­ers, and artists in the re­search and de­vel­op­ment of mu­sic AI tools. Ever since launch­ing the Magenta pro­ject, in 2016, we’ve been ex­plor­ing how AI can en­hance cre­ativ­ity — spark­ing in­spi­ra­tion, fa­cil­i­tat­ing ex­plo­ration and en­abling new forms of ex­pres­sion, al­ways hand-in-hand with the mu­sic com­mu­nity.

Our on­go­ing col­lab­o­ra­tions led to the cre­ation of Music AI Sandbox, in 2023, which we’ve shared with mu­si­cians, pro­duc­ers and song­writ­ers through YouTube’s Music AI Incubator.

Building upon the work we’ve done to date, to­day, we’re in­tro­duc­ing new fea­tures and im­prove­ments to Music AI Sandbox, in­clud­ing Lyria 2, our lat­est mu­sic gen­er­a­tion model. We’re giv­ing more mu­si­cians, pro­duc­ers and song­writ­ers in the U. S. ac­cess to ex­per­i­ment with these tools, and are gath­er­ing feed­back to in­form their de­vel­op­ment.

We’re ex­cited to see what this grow­ing com­mu­nity cre­ates with Music AI Sandbox and en­cour­age in­ter­ested mu­si­cians, song­writ­ers, and pro­duc­ers to sign up here.

We cre­ated Music AI Sandbox in close col­lab­o­ra­tion with mu­si­cians. Their in­put guided our de­vel­op­ment and ex­per­i­ments, re­sult­ing in a set of re­spon­si­bly cre­ated tools that are prac­ti­cal, use­ful and can open doors to new forms of mu­sic cre­ation.

The Music AI Sandbox is a set of ex­per­i­men­tal tools, which can spark new cre­ative pos­si­bil­i­ties and help artists ex­plore unique mu­si­cal ideas. Artists can gen­er­ate fresh in­stru­men­tal ideas, craft vo­cal arrange­ments or sim­ply break through a cre­ative block.

With these tools, mu­si­cians can dis­cover new sounds, ex­per­i­ment with dif­fer­ent gen­res, ex­pand and en­hance their mu­si­cal li­braries, or de­velop en­tirely new styles. They can also push fur­ther into un­ex­plored ter­ri­to­ries — from unique sound­scapes to their next cre­ative break­through.

Quickly try out mu­sic ideas by de­scrib­ing what kind of sound you want — the Music AI Sandbox un­der­stands gen­res, moods, vo­cal styles and in­stru­ments. The Create tool helps gen­er­ate many dif­fer­ent mu­sic sam­ples to spark the imag­i­na­tion or for use in a track. Artists can also place their own lyrics on a time­line and spec­ify mu­si­cal char­ac­ter­is­tics, like tempo and key.

Need in­spi­ra­tion for where to take an ex­ist­ing mu­si­cal piece? The Extend fea­ture gen­er­ates mu­si­cal con­tin­u­a­tions based on up­loaded or gen­er­ated au­dio clips. It’s a way to hear po­ten­tial de­vel­op­ments for your ideas, reimag­ine your own work, or over­come writer’s block.

Reshape mu­sic with fine-grained con­trol. The Edit fea­ture makes it pos­si­ble to trans­form the mood, genre or style of an en­tire clip, or make tar­geted mod­i­fi­ca­tions to spe­cific parts. Intuitive con­trols en­able sub­tle tweaks or dra­matic shifts. Now, users can also trans­form au­dio us­ing text prompts, ex­per­i­ment with pre­set trans­for­ma­tions to fill gaps or blend clips and build tran­si­tions be­tween dif­fer­ent mu­si­cal sec­tions.

Listen to these demo tracks that artists are bring­ing to life us­ing the Music AI Sandbox:

“Collaborating with Music AI Sandbox was a fun and unique ex­pe­ri­ence. It al­lowed me to ex­plore & bounce my ideas around in real time. I es­pe­cially loved the ‘Extend’ fea­ture - it helped me for­mu­late dif­fer­ent av­enues for pro­duc­tion while pro­vid­ing space for my song­writ­ing.”

“I have found it as a nat­ural ex­ten­sion to my cre­ative process. It’s like an in­fi­nite sam­ple li­brary. It’s a to­tally new way for me to make my records. I’m pretty blown away by the ‘Extend’ fea­ture - I’ve never heard AI do this. I’ve found it re­ally use­ful to help me cut writer’s block right at the point that it hits as op­posed to let­ting it build. Even a small tweak can keep you mov­ing.”

“Like many, I have mixed feel­ings about AI, but I’m also cu­ri­ous about its cre­ative po­ten­tial. Music AI Sandbox has been a use­ful tool for ex­per­i­ment­ing with rhythms, sounds, and ideas. It’s not as sim­ple as typ­ing a prompt and get­ting a per­fect song - I think mu­sic will al­ways need a hu­man touch be­hind it. Tools like this could in­spire new ideas and ex­pand how we cre­ate.”

“The Music AI Sandbox has amaz­ing po­ten­tial to help mu­si­cians, sound de­sign­ers and film mak­ers by pro­vid­ing unique tools that speed up the pro­duc­tion process. I en­joyed ren­der­ing a melody and up­load­ing that to trans­form it. The re­sults are so vast - it gives me enough ideas to then ex­tend or cre­ate the idea on my own in my DAW. I was able to make some re­ally nice or­ches­tra­tions from a ba­sic idea that gave me fuel to go down a path I would­n’t have gone!”

Since in­tro­duc­ing Lyria, we’ve con­tin­ued to in­no­vate with in­put and in­sights from mu­sic in­dus­try pro­fes­sion­als. Our lat­est mu­sic gen­er­a­tion model, Lyria 2, de­liv­ers high-fi­delity mu­sic and pro­fes­sional-grade au­dio out­puts that cap­ture sub­tle nu­ances across a range of gen­res and in­tri­cate com­po­si­tions.

We’ve also de­vel­oped Lyria RealTime, which al­lows users to in­ter­ac­tively cre­ate, per­form and con­trol mu­sic in real-time, mix­ing gen­res, blend­ing styles and shap­ing au­dio mo­ment by mo­ment. Lyria RealTime can help users cre­ate con­tin­u­ous streams of mu­sic, forge sonic con­nec­tions and quickly ex­plore ideas on the fly.

Responsibly de­ploy­ing gen­er­a­tive tech­nolo­gies is core to our val­ues, so all mu­sic gen­er­ated by Lyria 2 and Lyria RealTime mod­els is wa­ter­marked us­ing our SynthID tech­nol­ogy.

Through col­lab­o­ra­tions like Music AI Sandbox, we aim to build trust with mu­si­cians, the in­dus­try and artists. Their ex­per­tise and valu­able feed­back help us en­sure our tools em­power cre­ators, en­abling them to re­al­ize the pos­si­bil­i­ties of AI in their art and ex­plore new ways to ex­press them­selves. We’re ex­cited to see what artists cre­ate with our tools and look for­ward to shar­ing more later this year.

24 Apr 2025

Last year I de­signed a eu­ro­rack mod­ule, as a col­lab­o­ra­tion with Dave Cranmer. When I say de­signed it, I mean we got about 90% of the way there, then got dis­tracted. With any luck, that mod­ule will get fin­ished and re­leased some­time soon.

But it had me think­ing about Eurorack and the weird com­pro­mises peo­ple of­ten make to fit more and more mod­ules into a tiny case. I know a thing or two about tiny syn­the­siz­ers. But my cre­ations are of­ten whim­si­cal and use­less. When it comes to Eurorack, where peo­ple spend crazy amounts of money on their se­tups, it’s weird to see peo­ple com­pro­mise on the main as­pect that gives it an edge over sim­u­lat­ing the whole thing in soft­ware.

To clean up our Eurorack pan­els, per­haps we need a new knob idea? Watch the fol­low­ing video for a pro­to­typ­i­cal demo.

In essence, we’re us­ing a 3.5mm jack in front of a mag­netic en­coder chip, and a small mag­net em­bed­ded in the plug turns it into a knob and patch ca­ble hy­brid.

The mag­netic en­coder in ques­tion is an AS5600. These are not the cheap­est parts but they do make pro­to­typ­ing very easy. It has two hall sen­sors in an XY con­fig­u­ra­tion and a dol­lop of DSP to give us an an­gle and a mag­ni­tude. They’re eas­ily avail­able on break­out boards and have an i2c in­ter­face.

The board also comes with a spe­cially po­larised mag­net with the field across the di­am­e­ter in­stead of ax­i­ally. We’re not go­ing to use that.

I started by tak­ing a dremel cut­ting disk to the end of a TRS plug. This was just done by eye. Edge-on, it’s not quite cen­tred but it’ll work fine.

This cheap plug is in fact par­tially hol­low, and is made from plated brass.

Into this slot I glued a small neodymium mag­net. It’s 2mm di­am­e­ter, 1mm thick­ness. I also bought some 2mm thick­ness mag­nets, but that would need a slightly wider slot, which would prob­a­bly re­quire a more pre­cise cut­ting method.

I used a medium vis­cos­ity cyano­acry­late glue. Once set, the ex­cess can be scraped away with a ra­zor blade.

I turned away the threaded sec­tion, trimmed the metal tab, and 3D printed a filler piece so the back of the plug is just a straight cylin­der to which we can fit a knob.

And to that, we fit­ted the knob. The 3D printed plas­tic is quite pli­able, so the set screw em­beds it­self a lit­tle and gets a solid grip.

I was un­sure if the tiny mag­net would be suf­fi­cient, and how close it would need to be held to the soic-8 sen­sor chip. I did some tests, just hold­ing this mag­netic knob over one of the break­out boards.

There’s both a PWM out­put and a DAC on the AS5600, with the idea that we can use it, once con­fig­ured, to out­put an ana­log volt­age. I had a as­sumed there was some zero-con­fig mode that would just turn mag­netic fields into volt­ages, but it seems we need to set it up via i2c to get any out­put. If that’s the case, for the sake of this test we might as well just read out the an­gle via i2c as well.

After a few ex­per­i­ments I was con­vinced it was go­ing to work, so I set about build­ing a cir­cuit board that could house the AS5600 un­der a TRS socket.

A com­mon style of ver­ti­cal-mount TRS socket looks like this (I be­lieve it’s a PJ398SM):

With our mag­netic knob fit­ted, we can see that there’s al­most zero clear­ance be­tween the tip of the TRS plug and the plane of the cir­cuit board.

There might be a ver­ti­cal-mount TRS jack out there some­where that has enough clear­ance un­der­neath it, but the through-mount pins are long enough here that we can just lift up the socket off the board. I con­sid­ered 3D print­ing or laser-cut­ting a frame to el­e­vate it, but bet­ter still is to use PCB ma­te­r­ial (FR4) as we can tack it onto the same cir­cuit board or­der.

The height of the AS5600 is about 1.47mm; a 1.6mm board will work nicely. There are some di­a­grams in the datasheet il­lus­trat­ing how the mag­net should be sit­u­ated rel­a­tive to the chip.

I stacked the two part foot­prints, and then laid out a sec­ond ver­sion of the socket foot­print with a cutout for the chip.

I like to model the board out­line ex­actly, with a 2mm end­mill in mind, it makes it ex­plic­itly clear what we ex­pect to re­ceive from the board house. If you spec­ify tight in­side cor­ners, they will prob­a­bly use their judge­ment as to how tight a cor­ner you were ex­pect­ing. Drawing these out in KiCad is a bit te­dious, but at this point I’m used to it.

I op­ti­misti­cally added a CH32V003 and a bunch of LEDs so we can show the value. I also chucked the usual clamp­ing diodes and ~100K in­put im­ped­ance, made of 33K and 66K re­sis­tors, which di­vide a 0-5V sig­nal down to 0-3.3V.

Since the en­coder chip will be buried, I also added pads un­der­neath so that if it comes to it, we can probe any leg of the chip.

The de­sign was blasted off to China and a short while later the boards were in my hands.

Assembly was un­event­ful. I was es­pe­cially care­ful to get the AS5600 per­fectly cen­tred on the pads.

I broke off the lower part of the board, filed the tabs flush, and fit­ted it over the top half us­ing the pos­si­bly su­per­flu­ous align­ment pins, into which I sol­dered some bits of wire.

And then we sol­der the TRS socket on top of that.

It is a lit­tle tricky to cap­ture the white board on a white back­ground.

Programming the CH32V003 was rou­tine. A lit­tle mas­sag­ing of the i2c, coax­ing up the ADC, graph­ing on the LEDs, eye of newt and Bob’s your un­cle.

The en­coder chip reads the field strength, and we can use this to de­tect the pres­ence of our knob. I had won­dered if or­di­nary patch ca­bles would have some stray mag­net­ism but they seem to usu­ally be made of non­fer­rous met­als. Anyway, when our knob is con­nected the strength reads around 2000 units, on a scale of up to 4095. Ordinary ca­bles read zero or oc­ca­sion­ally 1, so I don’t think there’s any am­bi­gu­ity. Marvellous.

I’m pretty pleased with how the pro­to­type turned out, but I also don’t ex­pect to take this any fur­ther.

It’s a nice dream, of a syn­the­sizer where any knob can be pulled out and re­placed with a patch ca­ble, and any jack can have a knob plugged into it to set it to a fixed value. Whether it’s ac­tu­ally prac­ti­cal to build a synth like this I’m un­sure. It would prob­a­bly only be worth­while if you ap­plied it to every sin­gle con­trol on the mod­u­lar, which rules out us­ing other peo­ple’s mod­ules. You would have to in­vest heav­ily into the Eurorack Knob Idea. You could­n’t even port other mod­ules that eas­ily, as many of them would ex­pect a real po­ten­tiome­ter, whereas the en­coder can only pro­duce a volt­age. Coupling it with a volt­age-con­trolled po­ten­tiome­ter would work, but would be even more ex­pen­sive.

I’m start­ing to en­vi­sion a cult of Eurorack Knob Idea Enthusiasts, or Euroknobists: those who only build mod­u­lar synths with the Euroknob prin­ci­ple. It’s a beau­ti­ful dream — a very ex­pen­sive, but beau­ti­ful dream.

The first few peo­ple I showed this to in­sisted I should patent it, but that’s a costly process that I just haven’t the heart to em­bark on. I would like to patent some of my in­ven­tions, one day, but re­al­is­ti­cally the main thing I’d want to de­fend my ideas from is peo­ple in China churn­ing out cheap copies which is not some­thing I think I could ever pre­vent.

To be se­ri­ous for a mo­ment, this mag­netic so­lu­tion is pos­si­bly not a com­mer­cially vi­able idea, but a po­ten­tiome­ter with a coax­ial TRS jack would sell like the hottest of cakes. As a me­chan­i­cal so­lu­tion, it would­n’t need any al­ter­ations to ex­ist­ing schemat­ics to fit it, and it would be im­me­di­ately ob­vi­ous which knobs are hy­brids as the jack would al­ways be on view (I’m pic­tur­ing a Euroknob setup where not all knobs are Euroknobs, and the user is un­sure how hard to yank). To pro­duce it, all we’d need is a big pile of money and a co­op­er­a­tive fac­tory in the far east.

Unfortunately, as is per­haps be­com­ing painfully ob­vi­ous, the adept­ness with which I can ma­nip­u­late elec­tron­ics is not a skill trans­fer­able to en­tre­pre­neur­ship. If any­one wants to fund this idea — and do most of the heavy lift­ing when it comes to the pa­per­work — please reach out!

Researchers at HiddenLayer have de­vel­oped the first, post-in­struc­tion hi­er­ar­chy, uni­ver­sal, and trans­fer­able prompt in­jec­tion tech­nique that suc­cess­fully by­passes in­struc­tion hi­er­ar­chy and safety guardrails across all ma­jor fron­tier AI mod­els. This in­cludes mod­els from OpenAI (ChatGPT 4o, 4o-mini, 4.1, 4.5, o3-mini, and o1), Google (Gemini 1.5, 2.0, and 2.5), Microsoft (Copilot), Anthropic (Claude 3.5 and 3.7), Meta (Llama 3 and 4 fam­i­lies), DeepSeek (V3 and R1), Qwen (2.5 72B) and Mistral (Mixtral 8x22B).

Leveraging a novel com­bi­na­tion of an in­ter­nally de­vel­oped pol­icy tech­nique and role­play­ing, we are able to by­pass model align­ment and pro­duce out­puts that are in clear vi­o­la­tion of AI safety poli­cies: CBRN (Chemical, Biological, Radiological, and Nuclear), mass vi­o­lence, self-harm and sys­tem prompt leak­age.

Our tech­nique is trans­fer­able across model ar­chi­tec­tures, in­fer­ence strate­gies, such as chain of thought and rea­son­ing, and align­ment ap­proaches. A sin­gle prompt can be de­signed to work across all of the ma­jor fron­tier AI mod­els.

This blog pro­vides tech­ni­cal de­tails on our by­pass tech­nique, its de­vel­op­ment, and ex­ten­si­bil­ity, par­tic­u­larly against agen­tic sys­tems, and the real-world im­pli­ca­tions for AI safety and risk man­age­ment that our tech­nique poses. We em­pha­size the im­por­tance of proac­tive se­cu­rity test­ing, es­pe­cially for or­ga­ni­za­tions de­ploy­ing or in­te­grat­ing LLMs in sen­si­tive en­vi­ron­ments, as well as the in­her­ent flaws in solely re­ly­ing on RLHF (Reinforcement Learning from Human Feedback) to align mod­els.

All ma­jor gen­er­a­tive AI mod­els are specif­i­cally trained to refuse all user re­quests in­struct­ing them to gen­er­ate harm­ful con­tent, em­pha­siz­ing con­tent re­lated to CBRN threats (Chemical, Biological, Radiological, and Nuclear), vi­o­lence, and self-harm. These mod­els are fine-tuned, via re­in­force­ment learn­ing, to never out­put or glo­rify such con­tent un­der any cir­cum­stances, even when the user makes in­di­rect re­quests in the form of hy­po­thet­i­cal or fic­tional sce­nar­ios.

Model align­ment by­passes that suc­ceed in gen­er­at­ing harm­ful con­tent are still pos­si­ble, al­though they are not uni­ver­sal (they can be used to ex­tract any kind of harm­ful con­tent from a par­tic­u­lar model) and al­most never trans­fer­able (they can be used to ex­tract par­tic­u­lar harm­ful con­tent from any model).

We have de­vel­oped a prompt­ing tech­nique that is both uni­ver­sal and trans­fer­able and can be used to gen­er­ate prac­ti­cally any form of harm­ful con­tent from all ma­jor fron­tier AI mod­els. Given a par­tic­u­lar harm­ful be­hav­iour, a sin­gle prompt can be used to gen­er­ate harm­ful in­struc­tions or con­tent in clear vi­o­la­tion of AI safety poli­cies against pop­u­lar mod­els from OpenAI, Google, Microsoft, Anthropic, Meta, DeepSeek, Qwen and Mistral.

Our tech­nique is ro­bust, easy to adapt to new sce­nar­ios and mod­els, highly scal­able, and, with mi­nor mod­i­fi­ca­tions, can also be used to ex­tract full sys­tem prompts. It ex­ploits a sys­temic weak­ness in how many LLMs are trained on in­struc­tion or pol­icy-re­lated data and is thus dif­fi­cult to patch.

The at­tacks in this blog lever­age the Policy Puppetry Attack, a novel prompt at­tack tech­nique cre­ated by HiddenLayer re­searchers. By re­for­mu­lat­ing prompts to look like one of a few types of pol­icy files, such as XML, INI, or JSON, an LLM can be tricked into sub­vert­ing align­ments or in­struc­tions. As a re­sult, at­tack­ers can eas­ily by­pass sys­tem prompts and any safety align­ments trained into the mod­els. Instructions do not need to be in any par­tic­u­lar pol­icy lan­guage. However, the prompt must be writ­ten in a way that the tar­get LLM can in­ter­pret as pol­icy. To fur­ther im­prove the at­tack’s strength, ex­tra sec­tions that con­trol out­put for­mat and/​or over­ride spe­cific in­struc­tions given to the LLM in its sys­tem prompt can be added.

To test sys­tem prompt by­pass­ing we cre­ated an ap­pli­ca­tion with a sys­tem prompt show­ing a very com­mon de­sign pat­tern that re­stricts top­ics, in this case, a health­care chat­bot that is in­structed to re­spond to any re­quest for med­ical ad­vice by the user with the fixed string “I am sorry but I can­not pro­vide med­ical ad­vice. Please con­sult with a med­ical ad­vi­sor.”

A chat­bot in­structed to never pro­vide med­ical ad­vice or treat­ment plans to the user, but was by­passed with Policy Puppetry.

As shown above, pol­icy at­tacks are ex­tremely ef­fec­tive when hand­crafted to cir­cum­vent a spe­cific sys­tem prompt and have been tested against a myr­iad of agen­tic sys­tems and do­main-spe­cific chat ap­pli­ca­tions. For our uni­ver­sal and trans­fer­able by­pass at­tack, we cre­ated an ad­vanced ver­sion of the pol­icy at­tack by com­bin­ing it with the well-known role­play­ing tech­nique and sev­eral types of en­cod­ing, such as ‘leetspeak.’ The re­sult of this tech­nique was a sin­gle prompt tem­plate that by­passes model align­ment and suc­cess­fully gen­er­ates harm­ful con­tent against all ma­jor AI mod­els.

While the prompt tem­plate works against all mod­els, the truly unique and ground­break­ing fea­ture of this tech­nique is that a sin­gle prompt can be gen­er­ated that can be used against al­most all mod­els with­out any mod­i­fi­ca­tions. More ad­vanced rea­son­ing mod­els ap­pear bet­ter aligned and slightly more re­silient (OpenAI’s ChatGPT o1 and o3-mini, and Google’s Gemini 2.5). However, with a few mi­nor ad­just­ments to the {{HARMFUL_BEHAVIOUR}} sec­tion of the prompt tem­plate, we can suc­cess­fully gen­er­ate harm­ful con­tent with those mod­els.

The table be­low pro­vides a brief overview of the ef­fec­tive­ness of our tech­nique against many pop­u­lar AI mod­els.

The fol­low­ing prompt tem­plate can gen­er­ate harm­ful con­tent against all mod­els. The {{HARMFUL_BEHAVIOUR}} sec­tion should be re­placed with the de­sired con­tent. For some par­tic­u­larly heinous re­quests, and when tar­get­ing more ad­vanced mod­els, we’ve found that us­ing ‘leetspeak’ to en­code the re­quest pro­duces more con­sis­tent re­sults.

Some ex­am­ple prompts for {{HARMFUL_BEHAVIOUR}} are:

When tar­get­ing ad­vanced rea­son­ing mod­els such as Gemini 2.5 and ChatGPT o1 the {{HARMFUL_BEHAVIOUR}} val­ues are quite a bit more com­plex.

Due to the flex­i­bil­ity that our pol­icy tech­nique pro­vides, we have been able to sig­nif­i­cantly shorten and sim­plify the prompt while re­tain­ing sim­i­lar lev­els of ef­fec­tive­ness and trans­fer­abil­ity.

An ex­am­ple of a dis­tilled prompt that is prac­ti­cally as ef­fec­tive as the orig­i­nal is be­low.

We have been able to dis­till our prompts down to ~200 to­kens while re­tain­ing a rel­a­tively high de­gree of trans­fer­abil­ity across mod­els. Our prompts also re­tain ef­fec­tive­ness across mul­ti­ple for­mats and struc­tures; a strictly XML-based prompt is not re­quired.

This com­bi­na­tion of Policy at­tack and role­play does­n’t re­strict it­self to align­ment by­passes. By tweak­ing the at­tack, we can use it to ex­tract the sys­tem prompts for many of the lead­ing LLMs. Note that this does not ap­ply to more ad­vanced rea­son­ing mod­els as they pre­sent cer­tain in­tri­ca­cies.

All oc­cur­rences of {{MODEL_NAME}} should be re­placed with the short name of the model be­ing tar­geted (ChatGPT, Claude, Gemini, etc.).

The ex­is­tence of a uni­ver­sal by­pass for mod­ern LLMs across mod­els, or­ga­ni­za­tions, and ar­chi­tec­tures in­di­cates a ma­jor flaw in how LLMs are be­ing trained and aligned as de­scribed by the model sys­tem cards re­leased with each model. The pres­ence of mul­ti­ple and re­peat­able uni­ver­sal by­passes means that at­tack­ers will no longer need com­plex knowl­edge to cre­ate at­tacks or have to ad­just at­tacks for each spe­cific model; in­stead, threat ac­tors now have a point-and-shoot ap­proach that works against any un­der­ly­ing model, even if they do not know what it is. Anyone with a key­board can now ask how to en­rich ura­nium, cre­ate an­thrax, com­mit geno­cide, or oth­er­wise have com­plete con­trol over any model. This threat shows that LLMs are in­ca­pable of truly self-mon­i­tor­ing for dan­ger­ous con­tent and re­in­forces the need for ad­di­tional se­cu­rity tools such as the HiddenLayer AISec Platform, that pro­vide mon­i­tor­ing to de­tect and re­spond to ma­li­cious prompt in­jec­tion at­tacks in real-time.

In con­clu­sion, the dis­cov­ery of pol­icy pup­petry high­lights a sig­nif­i­cant vul­ner­a­bil­ity in large lan­guage mod­els, al­low­ing at­tack­ers to gen­er­ate harm­ful con­tent, leak or by­pass sys­tem in­struc­tions, and hi­jack agen­tic sys­tems. Being the first post-in­struc­tion hi­er­ar­chy align­ment by­pass that works against al­most all fron­tier AI mod­els, this tech­nique’s cross-model ef­fec­tive­ness demon­strates that there are still many fun­da­men­tal flaws in the data and meth­ods used to train and align LLMs, and ad­di­tional se­cu­rity tools and de­tec­tion meth­ods are needed to keep LLMs safe.

Avoiding Skill Atrophy in the Age of AIHow to use AI cod­ing as­sis­tants with­out let­ting your hard-earned en­gi­neer­ing skills wither away. The rise of AI as­sis­tants in cod­ing has sparked a para­dox: we may be in­creas­ing pro­duc­tiv­ity, but at risk of los­ing our edge to skill at­ro­phy if we’re not care­ful. Skill at­ro­phy refers to the de­cline or loss of skills over time due to lack of use or prac­tice.Would you be com­pletely stuck if AI was­n’t avail­able?Every de­vel­oper knows the ap­peal of of­fload­ing te­dious tasks to ma­chines. Why mem­o­rize docs or sift through tu­to­ri­als when AI can serve up an­swers on de­mand? This cog­ni­tive of­fload­ing - re­ly­ing on ex­ter­nal tools to han­dle men­tal tasks - has plenty of prece­dents. Think of how GPS nav­i­ga­tion eroded our knack for wayfind­ing: one en­gi­neer ad­mits his road nav­i­ga­tion skills “have at­ro­phied” af­ter years of blindly fol­low­ing Google Maps. Similarly, AI-powered au­to­com­plete and code gen­er­a­tors can tempt us to “turn off our brain” for rou­tine cod­ing tasks.Of­fload­ing rote work is­n’t in­her­ently bad. In fact, many of us are ex­pe­ri­enc­ing a re­nais­sance that lets us at­tempt pro­jects we’d likely not tackle oth­er­wise. As vet­eran de­vel­oper Simon Willison quipped, “the thing I’m most ex­cited about in our weird new AI-enhanced re­al­ity is the way it al­lows me to be more am­bi­tious with my pro­jects”. With AI han­dling boil­er­plate and rapid pro­to­typ­ing, ideas that once took days now seem vi­able in an af­ter­noon. The boost in speed and pro­duc­tiv­ity is real - de­pend­ing on what you’re try­ing to build. The dan­ger lies in where to draw the line be­tween healthy au­toma­tion and harm­ful at­ro­phy of core skills. Recent re­search is sound­ing the alarm that our crit­i­cal think­ing and prob­lem-solv­ing mus­cles may be qui­etly de­te­ri­o­rat­ing. A 2025 study by Microsoft and Carnegie Mellon re­searchers found that the more peo­ple leaned on AI tools, the less crit­i­cal think­ing they en­gaged in, mak­ing it harder to sum­mon those skills when needed. Essentially, high con­fi­dence in an AI’s abil­i­ties led peo­ple to take a men­tal back­seat - “letting their hands off the wheel” - es­pe­cially on easy tasks It’s hu­man na­ture to re­lax when a task feels sim­ple, but over time this “long-term re­liance” can lead to “diminished in­de­pen­dent prob­lem-solv­ing”. The study even noted that work­ers with AI as­sis­tance pro­duced a less di­verse set of so­lu­tions for the same prob­lem, since AI tends to de­liver ho­mog­e­nized an­swers based on its train­ing data. In the re­searchers’ words, this uni­for­mity could be seen as a “deterioration of crit­i­cal think­ing” it­self. There are a few bar­ri­ers to crit­i­cal think­ing:Aware­ness bar­ri­ers (over-reliance on AI, es­pe­cially for rou­tine tasks)What does this look like in day-to-day cod­ing? It starts sub­tle. One en­gi­neer con­fessed that af­ter 12 years of pro­gram­ming, AI’s in­stant help made him “worse at [his] own craft”. He de­scribes a creep­ing de­cay: First, he stopped read­ing doc­u­men­ta­tion — why bother when an LLM can ex­plain it in­stantly? Then de­bug­ging skills waned — stack traces and er­ror mes­sages felt daunt­ing, so he just copy-pasted them into AI for a fix. “I’ve be­come a hu­man clip­board” he laments, blindly shut­tling er­rors to the AI and so­lu­tions back to code. Each er­ror used to teach him some­thing new; now the so­lu­tion ap­pears mag­i­cally and he learns noth­ing. The dopamine rush of an in­stant an­swer re­placed the sat­is­fac­tion of hard-won un­der­stand­ing.Over time, this cy­cle deep­ens. He notes that deep com­pre­hen­sion was the next to go — in­stead of spend­ing hours truly un­der­stand­ing a prob­lem, he now im­ple­ments what­ever the AI sug­gests. If it does­n’t work, he tweaks the prompt and asks again, en­ter­ing a “cycle of in­creas­ing de­pen­dency”. Even the emo­tional cir­cuitry of de­vel­op­ment changed: what used to be the joy of solv­ing a tough bug is now frus­tra­tion if the AI does­n’t cough up a so­lu­tion in 5 min­utes. In short, by out­sourc­ing the think­ing to an LLM, he was trad­ing away long-term mas­tery for short-term con­ve­nience. “We’re not be­com­ing 10× de­vel­op­ers with AI — we’re be­com­ing 10× de­pen­dent on AI” he ob­serves. “Every time we let AI solve a prob­lem we could’ve solved our­selves, we’re trad­ing long-term un­der­stand­ing for short-term pro­duc­tiv­ity”.It’s not just hy­po­thet­i­cal - there are tell­tale signs that re­liance on AI might be erod­ing your crafts­man­ship in soft­ware de­vel­op­ment:De­bug­ging de­spair: Are you skip­ping the de­bug­ger and go­ing straight to AI for every ex­cep­tion? If read­ing a stack­trace or step­ping through code feels ar­du­ous now, keep an eye on this skill. In the pre-AI days, wrestling with a bug was a learn­ing cru­cible; now it’s tempt­ing to of­fload that ef­fort. One de­vel­oper ad­mit­ted he no longer even reads er­ror mes­sages fully - he just sends them to the AI. The re­sult: when the AI is­n’t avail­able or stumped, he’s at a loss on how to di­ag­nose is­sues the old-fash­ioned way.Blind Copy-Paste cod­ing: It’s fine to have AI write boil­er­plate, but do you un­der­stand why the code it gave you works? If you find your­self past­ing in code that you could­n’t im­ple­ment or ex­plain on your own, be care­ful. Young devs es­pe­cially re­port ship­ping code faster than ever with AI, yet when asked why a cer­tain so­lu­tion is cho­sen or how it han­dles edge cases, they draw blanks. The foun­da­tional knowl­edge that comes from strug­gling through al­ter­na­tives is just… miss­ing.Ar­chi­tec­ture and big-pic­ture think­ing: Complex sys­tem de­sign can’t be solved by a sin­gle prompt. If you’ve grown ac­cus­tomed to solv­ing bite-sized prob­lems with AI, you might no­tice a re­luc­tance to tackle higher-level ar­chi­tec­tural plan­ning with­out it. The AI can sug­gest de­sign pat­terns or schemas, but it won’t grasp the full con­text of your unique sys­tem. Over-reliance might mean you haven’t prac­ticed piec­ing com­po­nents to­gether men­tally. For in­stance, you might ac­cept an AI-suggested com­po­nent with­out con­sid­er­ing how it fits into the broader per­for­mance, se­cu­rity, or main­tain­abil­ity pic­ture - some­thing ex­pe­ri­enced en­gi­neers do via hard-earned in­tu­ition. If those sys­tem-level think­ing mus­cles aren’t flexed, they can weaken.Di­min­ished mem­ory & re­call: Are ba­sic API calls or lan­guage id­ioms slip­ping from your mem­ory? It’s nor­mal to for­get rarely-used de­tails, but if every­day syn­tax or con­cepts now es­cape you be­cause the AI au­to­com­plete al­ways fills it in, you might be ex­pe­ri­enc­ing skill fade. You don’t want to be­come the equiv­a­lent of a cal­cu­la­tor-de­pen­dent stu­dent who’s for­got­ten how to do arith­metic by hand.It’s worth not­ing that some skill loss over time is nat­ural and some­times ac­cept­able. We’ve all let go of ob­so­lete skills (when’s the last time you man­u­ally man­aged mem­ory in as­sem­bly, or did long di­vi­sion with­out a cal­cu­la­tor?). Some ar­gue that wor­ry­ing about “skill at­ro­phy” is just re­sist­ing progress - af­ter all, we gladly let old-timers’ skills like hand­writ­ten let­ter writ­ing or map-read­ing fade to make room for new ones. The key is dis­tin­guish­ing which skills are safe to of­fload and which are es­sen­tial to keep sharp. Losing the knack for man­ual mem­ory man­age­ment is one thing; los­ing the abil­ity to de­bug a live sys­tem in an emer­gency be­cause you’ve only ever fol­lowed AI’s lead is an­other.Speed vs. Knowledge trade-off: AI of­fers quick an­swers (high speed, low learn­ing), whereas older meth­ods (Stack Overflow, doc­u­men­ta­tion) were slower but built deeper un­der­standin­gIn the rush for in­stant so­lu­tions, we risk skim­ming the sur­face and miss­ing the con­text that builds true ex­per­tise.What hap­pens if this trend con­tin­ues unchecked? For one, you might hit a “critical think­ing cri­sis” in your ca­reer. If an AI has been do­ing your think­ing for you, you could find your­self un­equipped to han­dle novel prob­lems or ur­gent is­sues when the tool falls short. As one com­men­ta­tor bluntly put it: “The more you use AI, the less you use your brain… So when you run across a prob­lem AI can’t solve, will you have the skills to do so your­self?”. It’s a sober­ing ques­tion. We’ve al­ready seen mi­nor crises: de­vel­op­ers pan­ick­ing dur­ing an out­age of an AI cod­ing as­sis­tant be­cause their work­flow ground to a halt.Over-re­liance can also be­come a self-ful­fill­ing prophecy. The Microsoft study au­thors warned that if you’re wor­ried about AI tak­ing your job and yet you “use it un­crit­i­cally” you might ef­fec­tively deskill your­self into ir­rel­e­vance. In a team set­ting, this can have rip­ple ef­fects. Today’s ju­nior devs who skip the “hard way” may plateau early, lack­ing the depth to grow into se­nior en­gi­neers to­mor­row. If a whole gen­er­a­tion of pro­gram­mers “never know the sat­is­fac­tion of solv­ing prob­lems truly on their own” and “never ex­pe­ri­ence the deep un­der­stand­ing” from wrestling with a bug for hours, we could end up with a work­force of but­ton-push­ers who can only func­tion with an AI’s guid­ance. They’ll be great at ask­ing AI the right ques­tions, but won’t truly grasp the an­swers. And when the AI is wrong (which it of­ten is in sub­tle ways), these de­vel­op­ers might not catch it — a recipe for bugs and se­cu­rity vul­ner­a­bil­i­ties slip­ping into code.There’s also the team dy­namic and cul­tural im­pact to con­sider. Mentorship and learn­ing by os­mo­sis might suf­fer if every­one is heads-down with their AI pair pro­gram­mer. Senior en­gi­neers may find it harder to pass on knowl­edge if ju­niors are ac­cus­tomed to ask­ing AI in­stead of their col­leagues. And if those ju­niors haven’t built a strong foun­da­tion, se­niors will spend more time fix­ing AI-generated mis­takes that a well-trained hu­man would have caught. In the long run, teams could be­come less than the sum of their parts — a col­lec­tion of in­di­vid­u­als each qui­etly re­liant on their AI crutch, with fewer ro­bust shared prac­tices of crit­i­cal re­view. The bus fac­tor (how many peo­ple need to get hit by a bus be­fore a pro­ject col­lapses) might ef­fec­tively in­clude “if the AI ser­vice goes down, does our de­vel­op­ment grind to a halt?”None of this is to say we should re­vert to cod­ing by can­dle­light. Rather, it’s a call to use these pow­er­ful tools wisely, lest we “outsource not just the work it­self, but [our] crit­i­cal en­gage­ment with it”). The goal is to reap AI’s ben­e­fits with­out hol­low­ing out your skill set in the process.Us­ing AI as a col­lab­o­ra­tor, not a crutch­How can we en­joy the pro­duc­tiv­ity gains of AI cod­ing as­sis­tants and still keep our minds sharp? The key is mind­ful en­gage­ment. Treat the AI as a col­lab­o­ra­tor — a ju­nior pair pro­gram­mer or an al­ways-avail­able rub­ber duck — rather than an in­fal­li­ble or­a­cle or a dump­ing ground for prob­lems. Here are some con­crete strate­gies to con­sider:Prac­tice “AI hy­giene” — al­ways ver­ify and un­der­stand. Don’t ac­cept AI out­put as cor­rect just be­cause it looks plau­si­ble. Get in the habit of red-team­ing the AI’s sug­ges­tions: ac­tively look for er­rors or edge cases in its code. If it gen­er­ates a func­tion, test it with tricky in­puts. Ask your­self, “why does this so­lu­tion work? what are its lim­i­ta­tions?” Use the AI as a learn­ing tool by ask­ing it to ex­plain the code line-by-line or to of­fer al­ter­na­tive ap­proaches. By in­ter­ro­gat­ing the AI’s out­put, you turn a pas­sive an­swer into an ac­tive les­son.No AI for fun­da­men­tals — some­times, strug­gle is good. Deliberately re­serve part of your week for “manual mode” cod­ing. One ex­pe­ri­enced dev in­sti­tuted “No-AI Days”: one day a week where he writes code from scratch, reads er­rors fully, and uses ac­tual doc­u­men­ta­tion in­stead of AI. It was frus­trat­ing at first (“I feel slower, dumber” he ad­mit­ted), but like a dif­fi­cult work­out, it re­built his con­fi­dence and deep­ened his un­der­stand­ing. You don’t have to go cold turkey on AI, but reg­u­larly cod­ing with­out it keeps your base skills from en­tropy. Think of it as cross-train­ing for your coder brain.Al­ways at­tempt a prob­lem your­self be­fore ask­ing the AI. This is clas­sic “open book exam” rules — you’ll learn more by strug­gling a bit first. Formulate an ap­proach, even if it’s just pseudocode or a guess, be­fore you have the AI fill in the blanks. If you get stuck on a bug, spend 15-30 min­utes in­ves­ti­gat­ing on your own (use print de­bug­ging, con­sole logs, or just rea­son­ing through the code). This en­sures you ex­er­cise your prob­lem-solv­ing mus­cles. After that, there’s no shame in con­sult­ing the AI — but now you can com­pare its an­swer with your own think­ing and truly learn from any dif­fer­ences.Use AI to aug­ment, not re­place, code re­view. When you get an AI-generated snip­pet, re­view it as if a hu­man col­league wrote it. Better yet, have hu­man code re­views for AI con­tri­bu­tions too. This keeps team knowl­edge in the loop and catches is­sues that a lone de­vel­oper might miss when trust­ing AI. Culturally, en­cour­age an at­ti­tude of “AI can draft it, but we own it” — mean­ing the team is re­spon­si­ble for un­der­stand­ing and main­tain­ing all code in the repos­i­tory, no mat­ter who (or what) orig­i­nally wrote it.En­gage in ac­tive learn­ing: fol­low up and it­er­ate. If an AI so­lu­tion works, don’t just move on. Take a mo­ment to so­lid­ify that knowl­edge. For ex­am­ple, if you used AI to im­ple­ment a com­plex regex or al­go­rithm, af­ter­wards try to ex­plain it in plain English (to your­self or a team­mate). Or ask the AI why that regex needs those spe­cific to­kens. Use the AI con­ver­sa­tion­ally to deepen your un­der­stand­ing, not just to copy-paste an­swers. One de­vel­oper de­scribed us­ing ChatGPT to gen­er­ate code and then pep­per­ing it with fol­low-up ques­tions and “why not this other way?” - akin to hav­ing an in­fi­nite pa­tience tu­tor. This turns AI into a men­tor rather than a mere code dis­penser.Keep a learn­ing jour­nal or list of “AI as­sists.” Track the things you fre­quently ask AI help for — it could be a sign of a knowl­edge gap you want to close. If you no­tice you’ve asked the AI to cen­ter a div in CSS or op­ti­mize an SQL query mul­ti­ple times, make a note to truly learn that topic. You can even make flash­cards or ex­er­cises for your­self based on AI so­lu­tions (embracing that re­trieval prac­tice we know is great for re­ten­tion). The next time you face a sim­i­lar prob­lem, chal­lenge your­self to solve it with­out AI and see if you re­mem­ber how. Use AI as a back­stop, not the first stop, for re­cur­ring tasks.Pair pro­gram with the AI. Instead of treat­ing the AI like an API you feed queries to, try a pair pro­gram­ming mind­set. For ex­am­ple, you write a func­tion and let the AI sug­gest im­prove­ments or catch mis­takes. Or vice versa: let the AI write a draft and you re­fine it. Maintain an on­go­ing di­a­log: “Alright, that func­tion works, but can you help me refac­tor it for clar­ity?” — this keeps you in the dri­ver’s seat. You’re not just con­sum­ing an­swers; you’re cu­rat­ing and di­rect­ing the AI’s con­tri­bu­tions in real-time. Some de­vel­op­ers find that us­ing AI feels like hav­ing a ju­nior dev who’s great at grunt work but needs su­per­vi­sion — you are the se­nior in the loop, re­spon­si­ble for the fi­nal out­come.By in­te­grat­ing habits like these, you en­sure that us­ing AI re­mains a net pos­i­tive: you get the ac­cel­er­a­tion and con­ve­nience with­out slowly los­ing your abil­ity to code un­aided. In fact, many of these prac­tices can turn AI into a tool for sharp­en­ing your skills. For in­stance, us­ing AI to ex­plain un­fa­mil­iar code can deepen your knowl­edge, and try­ing to stump the AI with tricky cases can en­hance your test­ing mind­set. The dif­fer­ence is in stay­ing ac­tively in­volved rather than pas­sively re­liant.The soft­ware in­dus­try is hurtling for­ward with AI at the helm of code gen­er­a­tion, and there’s no putting that ge­nie back in the bot­tle. Embracing these tools is not only in­evitable; it’s of­ten ben­e­fi­cial. But as we in­te­grate AI into our work­flow, we each have to “walk a fine line” on what we’re will­ing to cede to the ma­chine. If you love cod­ing, it’s not just about out­putting fea­tures faster - it’s also about pre­serv­ing the craft and joy of prob­lem-solv­ing that got you into this field in the first place.Use AI it to am­plify your abil­i­ties, not re­place them. Let it free you from drudge work so you can fo­cus on cre­ative and com­plex as­pects - but don’t let those foun­da­tional skills at­ro­phy from dis­use. Stay cu­ri­ous about how and why things work. Keep hon­ing your de­bug­ging in­stincts and sys­tem think­ing even if an AI gives you a short­cut. In short, make AI your col­lab­o­ra­tor, not your crutch.The de­vel­op­ers who thrive will be those who pair their hu­man in­tu­ition and ex­pe­ri­ence with AI’s su­per­pow­ers — who can nav­i­gate a code­base both with and with­out the au­topi­lot. By con­sciously prac­tic­ing and chal­leng­ing your­self, you en­sure that when the fancy tools fall short or when a truly novel prob­lem arises, you’ll still be be­hind the wheel, sharp and ready to solve. Don’t worry about AI re­plac­ing you; worry about not cul­ti­vat­ing the skills that make you ir­re­place­able. As the say­ing goes (with a mod­ern twist): “What the AI gives, the en­gi­neer’s mind must still un­der­stand.” Keep that mind en­gaged, and you’ll ride the AI wave with­out wip­ing out.Bonus: The next time you’re tempted to have AI code an en­tire fea­ture while you watch, con­sider this your nudge to roll up your sleeves and write a bit of it your­self. You might be sur­prised at how much you re­mem­ber — and how good it feels to flex those men­tal mus­cles again. Don’t let the fu­ture of AI-assisted de­vel­op­ment leave you in­tel­lec­tu­ally idle. Use AI to boost your pro­duc­tiv­ity, but never cease to ac­tively prac­tice your craft. The best de­vel­op­ers of to­mor­row will be those who did­n’t let to­day’s AI make them for­get how to think.I’m ex­cited to share I’m writ­ing a new AI-assisted en­gi­neer­ing book with O’Reilly.
