I think the disconnect is that you assume that being able to do useful computation on some data implies that it must be possible to derive some insight into what the data is (side-channels or the like).

It's a fair assumption to start with. But the folks building FHE basically claim "nuh-uh", and I haven't seen anything to indicate they're wrong. Maybe some new Math grad will sort it out.

Die hard fans. I tried so many Claude models. Some are ok. Really. Surprisingly some versions of Sonnet are better than Opus. So the latest isn't always the greatest. Models are specialized sometimes (intentionally designed that way or not).

I think people just need to try a bunch to be honest. I think that we will get to a point (or are already there) where some models just resonate better with you and your communication (prompt) style.

But after using a bunch...I have to say that Gemini 2.5 Pro is consistently the best one I've used yet. It's pricey, but it just works.

I'm still looking for a good local model, but it's just going to be a while until anything local can match Gemini. It will eventually I think, but it'll take some time.

I probably won't be using Claude Code, but I'm glad it works for some folks.

Lately blablacar has been charging hitchhikers/travelers up front. So you as a driver know for sure you won't end up with nothing. This is really useful IMO, but also mostly significantly reduce the popularity of the service in places with low reliability among members.

In western Europe, particularly Germany, it was still very easy to find people, in eastern Europe, not so much. Even though before this change, years ago, blablacar was very popular in said eastern Europe countries.

It's open to things like sport and entertainment, so definitely not everyone has many (or any) degrees. Assuming your field is somewhat science based I don't know how realistic it would be with no degree, but you can search some blogs about it, people have covered what they did to rack up publications and stuff to check all the boxes (if their work/field wouldn't have otherwise needed them).

If you are starting your own business, the treaty investor visa could also be a good route. It doesn't require as much investment as the investor green card; it is a nonimmigrant visa similar to the O-1.

Government. About 25% of my job. No day to day mainframe development, but we do need to update some logic for new policies and regulations.

There’s not much maintenance work. There are very few bugs, as the core applications have been running for decades, most come up with interactions to external services.

Any major development projects are only in service of lower overall COBOL development time, like transitioning some business logic to database updates.

And there is a decommission plan for the mainframe, so plenty of work helping that team.

I wonder how much this is personal bias. I'm self-taught but I have absolutely no idea how I perform on the bell-curve against formally trained software developers.

From personal experience I've had to spend time learning concepts that I "ran into" that others already knew about. I probably spent a lot of time thinking I was good and clever enough to solve challenging problems... but then realize that I had used inappropriate data structures and made things more complicated than they needed to be because... I hacked my way through the problem rather than think through it from solid principles.

While I personally think experimentation is great... I've come to the conclusion that a mix of the theoretical and the practical is best. Being able to go back and forth between the two extremes has been valuable to me.

In order to make this work, libc would have to:

- Start some sort of async executor thread to service the io_uring requests/responses

- Make it so every call to "normal" syscalls causes the calling thread to sleep until the result is available (that's 1 syscall)

- When the executor thread gets a result, have it wake up the original thread (that's another syscall)

So you're basically turning 1 syscall into 2 in order to emulate the legacy syscalls.

io_uring only makes sense if you're already async. Emulating sync on top of async is nearly always a terrible idea.

Oh yes, I remember that when we swapped out a bunch of terminals at an airline.. The users complained it was all way too slow on the new Windows machines with MS SNA server in between... I was wondering what it was all about, as a young and very naive dropout from uni on his first IT job. When I came down, this dude was banging on his keyboard and after some time stopped, pointed at the screen and you could see it slowly catching up, screen by screen.. He showed me the directly connected version next. I learned something that day.

> Your assumption that operations leak info is just not correct.

My assumption is that you're right, that my assumption is incorrect. What I'm trying to do is understand why it's incorrect.

It's not just about operations leaking info, though, it's also an issue that, intuitively, leaving enough underlying structure in the encrypted form of the data to allow for this implies that the encrypted form is weaker. I'm also trying to understand how that intuition is wrong.

Edit: OK, The jeremykun link this comment provided gave me a little more clarity: https://news.ycombinator.com/item?id=44602472

I still don't adequately understand, but it does give me a little bit of a handle my brain can grab onto. As I understand it right now, HME is a weaker form of encryption, but perhaps still strong enough to be a worthwhile tradeoff for the use cases being discussed.

The article says it, "Cannot be waived", so does that mean that the thousands of people who travel under the ESTA visa waiver will suddenly need to find $250 (each, so $1000 for a family of four?), and to have the headache of potentially more forms at the end to get their money back again?

That seems like a lot of hassle if so, and will cause people to think twice about visiting the US.

Computer engineering will teach you that algorithmic complexity doesn’t mean squat if you can keep your data in CPU caches. The classic is any sort of connected node algorithm (linked list, graphs) which are stored sparsely in memory and therefore do not effectively utilize CPU caches.

I don’t know how it is elsewhere, but computer engineering here is regulated by the local engineering board — as the graduate can continue to become a professional engineer — and has much higher standards than the CS programs.

I still don’t think computer engineering programs teach anything that you cannot learn yourself, but the base bar of what is required to get a degree is higher than cs where I am.

I still use an Atom N270 netbook, and DuskOS is on the edge; but there are zillions of Atom netbooks in LaTam and in the outside as goverments agreed to ship these to students. With TUI/CLI tools you can do wonders, far more than CollapseOS. Yes, I know Forth, I did a good chunk of Starting Forth.

UXN once tweaked it can run stuff like Oquonie.

BTW, a properly set Emacs can double as a great legacy platform too; from IRC to whatever (Bitlbee<>IRC), Web browsing, email, gopher and gemini browser with elpher (and the Gemini proxy gemini://gemi.dev), epub reading, music and video (Emacs' emms, but mpv+yt-dlp can be set to play stuff at 480p/720@30FPS), Usenet client, RSS, Elisp itself, M-x calc and Gnuplot, PDF viewer (pdf-tools), Org-Mode+Hyperbole to expand your brain like nothing, sokoban gaming, Tetris, ZMachine text adventures with Malyon, MUDs, trace routers from OpenStreetMap with osm.el ...

For stucking I/O:

Usenet->slrnpull+GNUS.

Mail->Mu4e+mu.

People doesn't know that today computers from 2003 can do wonders and access far more services than they would think.

Once you can do TLS 1.3 'fast' enough (P4 w/ SSE2), you can do anything from IRC, email, gopher, gemini, usenet and rss from proxies and terminal or Emacs clients.

I highly recommend "Blinkist". It is an app with only audio book summaries and written summaries. It was a key step in my successful digital detox. The fact that they were summaries was easier do create daily habits.

Tip: In your digital detox, I also highly recommend an app like "Freedom" to block your time wasters. It's a bit like parental control but for yourself to timebox time spent on the news or HN.

Note: This won't help you personally but expect to help HN readers in general.

This just seems like a power grab to empower federal level personal thugs for the executive branch.

Most of these departments have rules about how they use our data. ICE now gobbles it all up and can use it without rules by a department that operates with little regard and lots of exceptions to typical protections for citizens afforded by the constitution.

The majority in SCOTUS does not seem to care (it’s ok as long as their guy does it). Whatever rules we thought there were seem to be out the window because someone magically moved data or ICE got to do it or so on ...

You could try transitioning more gradually by using your full-stack skills to create a website that you send data to via an embedded device (e.g. Pico or bare-metal system), either over Ethernet or WiFi. Even a simple dashboard with a table that shows e.g. HTTP or MQTT updates. For example, hook a temperature sensor up to a Pico or ESP32 (built-in WiFi/BT support), code it to periodically HTTP POST a JSON body with a timestamp, temperature value. Display the data on your website, maybe add tables and sorting, a graph(s) even, etc. That would make use of your existing skills, let you dabble in C and bare-metal programming, and combine the two to have something easily shown to prospective employers. (And show a product that is similar to existing real-world embedded applications)

I'm an embedded guy, the advice above is a reverse of what I've done in the past for clients: I wrote the embedded device firmware and dabbled a little in using .NET to create a portal for the customer to view and manage data from a fleet of devices reporting things like timestamp, battery level, temperature, etc.

Reverse osmosis filtering is brutal though. I think the most efficient ones are still like what, 1:2? 2 parts waste per one part clean water produced? It's a lot of wasted water. Even if it was 1:1 it would be terrible, that's doubling water usage.

Fine for drinking water, but showing/toilets/machines it's a lot.

And? Do you think the authorities would go to such extremes over a rock throwing incident if it didn't involve israel? Better yet, if it was the pro-israel counter-protestor throwing the rock, do you think the authorities would have wasted a second investigating the matter? Let alone breaking the law to get the suspect?

But they don’t do 80% of the task. They do 100% of the task, but 20% is wrong (and you don’t know which 20% without manually verifying all of it).

So it is really great for tasks where do the work is a lot harder than verifying it, and mostly useless for tasks where doing the work and verifying it are similarly difficult.

There’s a fundamental misunderstanding in claims that tech is riddled with incompetence just because some projects take years with little visible output. What’s often overlooked is the massive difference between building a customer-facing product and supporting the operations of a Fortune 500 enterprise. I’ve worked in both environments, and the contrast is stark.

Running a large business is hard. The complexity is amplified by fragmented leadership, shifting priorities, and competing agendas. The biggest opportunities for improvement often lie in streamlining enterprise systems, but these efforts are frequently derailed by internal politics. Requirements change daily. Alignment across stakeholders is elusive. And without unified leadership, even the best technical solutions can stall indefinitely.

Let’s be clear: the issue isn’t a lack of competence in tech. It’s a lack of cohesion and clarity in corporate leadership. Don’t confuse the symptoms with the root cause.

Not a dumb question at all! In Europe I’ve seen a few training programs held by companies looking to get new talent in to learn from the older techs. Browse around and see if any companies around you have something like that.

There are some free resources available that will allow you to get training but I haven’t tried them myself. IBM Z Xplore is worth a look as an example: https://www.ibm.com/products/z/resources/zxplore

I hope you find a way in, more mainframe developers and sysadmins(often called systemsprogrammers in the mainframe niche) are always needed.

Edit*: Spelling and grammar

> I often find trying to learn things on my own I start from differential calculus in this example and try to work backwards.

Doesn't everyone who has learned how to learn? Learning is way more efficient when you already have forward context for why you are learning something. Nebulously studying addition and subtraction without being able to see that it leads to multiplication (to stay with your example) is an absolutely horrid situation to find yourself in.

In fact, I suspect that's exactly what the article is really trying to get at: Those who "learn backwards", which happens to be a trait commonly associated with self-teaching, outperform.

Given they will inherit the mess being created now, I think the only moral choice is to allow 16 year olds to vote so they have a say in the future and ban anyone over about 65 or 75 from voting. They’re retired, not paying taxes and will not live long enough to fully reap the results of their vote. Society is not theirs anymore.

Thank you for the complement.

I am not so concerned about the anthropomorphizing language, which is technically incorrect but forgivable in communication, but with the practical factor that incorporating words or data points about time are not actually expressed in an experiential time dimension...

I would like to see timeline comprehension. Maybe this is that, but I couldn't tell and I kind of doubt it.

> I love that it doesn't auto-commit everything, ala aider, so it's pretty painless to undo stuff.

Yeah, I'm definitely glad it doesn't commit for me. The main issue I have is that I'm never sure how granular to make my commits. Sometimes I make them very granular because I'm experimenting with Claude and I want to be able to revert to any point in the conversation—but now I have to write a message each time to keep track of which is which. Conversely, when I don't make the commits as granular I loose the ability to roll back, and sometimes regret it.

Also, sometimes Claude gets a bit too smart! Let's say I decide I want Claude to try again with a slightly different prompt. I save my current changes in a branch, roll back, to the previous state, and ask Claude to try again. Sometimes Claude will say "I see this is already implemented in the XX branch. Let me continue to build on that implementation."

How does FHE help with someone executing a process on the server that affects the latency of your trading algo? eg by sucking up the CPU resources you need to do FHE.

How does FHE help with the fact that regulators generally want single-tenant shared-nothing for registered broker/dealers? Have you tried to explain a technical mitigation like FHE to a financial regulator? I have, there are 2 standard responses:

1) (in the US) "We strongly prefer single-tenant shared nothing. I won't officially say whether or not we deem your technical mitigation of using FHE to be sufficient. If we think it's insufficient we may take regulatory action against you in the future. Us not taking action doesn't mean we think it's sufficient."

2) (in places like Switzerland) "We strongly prefer single-tenant shared nothing. I'm not sure I fully understand the technical mitigation of FHE you are putting in place, but I'm going to increase your regulatory capital reserves. Send us some more white papers describing the solution and we may not increase your capital reserves further".

Singapore is the only exception where you have a regulator who is tech-savvy and will give you a clear answer as to whether something or not is OK.

Hi there, I'm working in the UK on a work visa. I previously applied for a US position at Fermilab and NASA ADS. Although, I didn't get the position I was told the H-1B visa process for these positions was much simpler (not through lottery) as they fall under a special category.

Can you advise other what other sectors offer these privileges? Also, if I get the H-1B through this process, am I allowed to switch to a different employer in the future?

What an absolutely asshole statement, which also shows an absolutely profound misunderstanding of suicide prevention and care.

Edit: Core belief of suicide ideation is that hope is gone. This is often (but not always) a perception. There may always be more things to try - but that's irrelevant to the person that is dead because they could not see another way.

Hmm, so it looks like no on really knows when it takes effect, the law itself specified a cost for the current fiscal year, but in addition to the usual time to implement the fee in the IT systems, there appear to be two issues: what rulemaking notices/approvals are needed to decide and impose it (the law allows the executive to decide the fee, it just sets a minimum), and the fact that DHS not State is supposed to collect it, which would greatly complicate processing.

State already has a global cashiering system for visa fees that would have been easier to use, although DHS collecting fees is not without precedent. For one, the SEVIS fee (a surcharge on student visas) is paid directly to DHS by credit card. For two, the surcharge on green cards is paid to USCIS, but this one is not actually enforced before visa issuance or arrival (they will not mail you the card if you don't pay, but you still have the status).

If more people want MRIs then the market will create more machines. And hopefully the tech will improve over time, though we might be waiting for room temperature superconductors for real progress.

Lack of staff to analyze the results is a problem, but not a huge one. Simply having a baseline to compare for later scans is valuable by itself, without any detailed analysis of the original.

> The police violated department policy to identify the student who hurled a rock at another student.

Allegedly. The article doesn't mention any evidence that he actually did.

> "Per the record before this court, there is no additional evidence connecting the defendant to the alleged incident — no surveillance video to and from his home, no independent identification by others in attendance."

No evidence.

> "This case is premised on the complainant's word that he was the target of criminal actions by another person, and that other person was the defendant."

Weak evidence (with potential bias.)

> "The NYPD digitally altered the defendant's DMV photograph [...] never sought the metadata which would clearly indicate how, when, and perhaps by whom the photo was doctored."

Manufactured evidence.

> "That statement alone renders these medical records discoverable as possible impeachment material, necessitating their disclosure [...] Yet the People [...] have articulated no efforts to obtain these records"

Withholding evidence from the defence.

All in all, utter bullshit from the prosecution.
