e12e··on Returning to Rails in 2026
I'd say that if you're first encounter with rails is version 8+ -- it's a lot easier to use than previous versions.

Partly because the handling of JavaScript is much less bespoke and complex.

e12e··on SBCL: A Sanely-Bootstrappable Common Lisp (2008) [pdf]
Current racket is running on top of chez scheme - which is maintained by Cisco - and reportedly extensively used in commercial products (router firmware/os etc).

e12e··on Ask HN: How to be alone?
I think when you've realized that you don't particularly enjoy being alone - the best cure is to avoid it; and try to get more friends.

Friends are made by doing something together, regularly, over time.

I wouldn't call this "get a hobby" - I'd call it "find something to do".

My best suggestion is start doing some kind of organized training like martial arts, or some team sport. Find somewhere to volunteer: food bank, volunteer programs teaching kids to code, anything in your area that you can relate to.

I'm not suggesting that it easy or trivial - but I also believe it is the only way.

Attacker reachable, presumably? Like from a hacked cable modem or wifi router?

It can be, if your typing is impaired.

It's nice to be able to authenticate sudo via biometric id with the help of Pam, or unlock your password manager like bitwarden.

I don't think an apple watch would help there?

e12e··on Bootc and OSTree: Modernizing Linux System Deployment
Not if someone else modified firewall rules while you were installing updates? (Eg: someone else being a Cron job).
e12e··on Our Agreement with the Department of War
Interestingly enough, even ChatGPT has this to say about how the Trump administration might side-step the language about fully autonomous weapons:

https://chatgpt.com/share/69a439b3-dfe4-800d-926e-39db221fba...

AI;DR

> So in summary: a future administration could attempt to sidestep those guardrails by altering the underlying legal/policy framework they’re tied to, redefining oversight requirements, or asserting emergency powers — effectively opening a path for more autonomous weapon deployments without facially violating the letter of the current contract text.

e12e··on Croatia declared free of landmines after 31 years
> a reliable mechanism for disabling

Note that the bar is pretty high for reliable here. Say 1 in a thousand isn't disarmed or destroyed.

Would you encourage your child to play in an area where ten thousand mines were dropped? A thousand? Five hundred?

e12e··on Bootc and OSTree: Modernizing Linux System Deployment
> A filesystem with snapshots makes software installation transactional. You take a snapshot, install some software, and if it doesn't work right, you can revert to the snapshot. (With very slightly more flexible snapshots, you can limit the snapshot to just some part of the directory tree, but this is not essential; it merely permits more flexibility.)

Eh, you don't typically have a lock mechanism for the filesystem equivalent to that of a database.

Who's to say something like this doesn't happen:

  - snapshot fs
  - op/system adjust firewall rules
  - "you" install updates
  - you rollback
  - firewall rules is now missing patches
Don't get me wrong zfs is great - but it doesn't come with magical transactions.
e12e··on Steel Bank Common Lisp
Replying while @dang is editing - so might be talking past current parent:

I suppose I shouldn't be surprised that Arc/clarc would be modified as news is modified (Arc sort of being built around news in the first place).

I just wouldn't expect there to be hn specific sauce in clarc that would make sense to excise if opening up clarc; AFAIK it's been stated that there's some secret sauce wrt fighting spam, detecting voting rings and so on...

Then again, thinking more about it, it sounds reasonable that some of that might land on the Arc/clarc side, not in news.

[Ed: I think that turned out quite well]

e12e··on Steel Bank Common Lisp
There's hn specific parts to the clarc implementation of Arc? (As opposed to the hn version of the "news" application)?

e12e··on The Missing Semester of Your CS Education – Revised for 2026
Fish is probably a good idea for an interactive shell. Osh/ysh might be a good idea for scripting:

https://oils.pub/

I'm still using bash out of habit, though. My one nod to modern tooling is using fzf for shell history search...

e12e··on The Missing Semester of Your CS Education – Revised for 2026
I think looking at some of the documentation for oils (née oil sh) and ysh - as well as [looking at using] these two projects [in place of bash] - is also a good idea today:

e12e··on California's new bill requires DOJ-approved 3D printers that report themselves
Clearly this is mostly security theatre (see eg comment about proving that them printer can't print a printer that can print a gun).

On the other hand - it would be low hanging fruit to prevent off the shelf printers to print well known gun parts? Much like photocopiers and scanners and printers won't scan, copy or print known currency bills?

e12e··on Japan's health ministry panel endorses 2 iPS cell-derived products
> The panel on Thursday recommended the manufacturing and sales of two iPS cell-derived products on condition that the two developers conduct studies involving all treated patients and further verify the efficacy and safety of their respective products within seven years.

> Cuorips, a startup originating from the University of Osaka, developed cardiomyocyte sheets for treating ischemic cardiomyopathy, a serious heart disease. Sumitomo Pharma submitted an application involving cells for transplantation into the brains of patients with Parkinson's disease, which causes symptoms including tremors in the limbs.

> The two companies had applied to manufacture and market the products last year.

e12e··on The Future of AI Software Development
In my mind, "yolo ai" application (throwaway code on one hand, unrestrained assistants on the other) - is a little like better spreadsheets and smart documents were in the 90s; just run macros! Everywhere! No need for developers - just Word an macros!

Then came macro viri - and practically - everyone cut back hard on distributing code via Word and Excel (in favour of web apps and we got the dot.com bubble).

e12e··on Asahi Linux Progress Report: Linux 6.19
The main thing that held me back from using Asahi on my M2 MacBook air - was missing external display. If I read TFA correctly - that should now work with a custom kernel.

If that's true - I'd say MacBook air M2 is probably the new sweetspot - depending on how cheap you could get an M1.

My impression is that until now, MacBook air M1 was the sweetspot.

It might be harder than you think. Any conditional fetch of an URL or DNS query could reveal some information.

> did not have egress to the Internet. It did have curl and Python, but not much else.

So trade exfiltration via curl with exfiltration via DNS lookup?

e12e··on Claude Sonnet 4.6
Is this referring to some section of the announcement?

This doesn't seem to align with the parent comment?

> As with every new Claude model, we’ve run extensive safety evaluations of Sonnet 4.6, which overall showed it to be as safe as, or safer than, our other recent Claude models. Our safety researchers concluded that Sonnet 4.6 has “a broadly warm, honest, prosocial, and at times funny character, very strong safety behaviors, and no signs of major concerns around high-stakes forms of misalignment.”

e12e··on Editor's Note: Retraction of article containing fabricated quotations
> (...) he should be fired for it.

I don't know about that - I'd say it's the managers responsibility to make sure employees don't feel pressured to work when they're to ill to function.

And also brings to mind the IBM one million dollars story:

(...)

A very large government bid, approaching a million dollars, was on the table. The IBM Corporation—no, Thomas J. Watson Sr.—needed every deal. Unfortunately, the salesman failed. IBM lost the bid. That day, the sales rep showed up at Mr. Watson’s office. He sat down and rested an envelope with his resignation on the CEO’s desk. Without looking, Mr. Watson knew what it was. He was expecting it.

He asked, “What happened?”

The sales rep outlined every step of the deal. He highlighted where mistakes had been made and what he could have done differently. Finally he said, “Thank you, Mr. Watson, for giving me a chance to explain. I know we needed this deal. I know what it meant to us.” He rose to leave.

Tom Watson met him at the door, looked him in the eye and handed the envelope back to him saying, “Why would I accept this when I have just invested one million dollars in your education?”
