> Heap-allocated trampolines have an obvious deallocation problem; it would be interesting to see what strategy is used for that.

With -ftrampoline-impl=heap, GCC automatically insert[1] pairs of constructor/destructor routines from libgcc which were built around mmap/munmap.

You've not understood what I said at all. I didn't ask for examples, I asked what you thought I was missing. Turns out I wasn't missing these things at all, we just disagree on the lessons learned there within. Fair enough, we can disagree, but to say I am denying it happened and not to do any different when my entire point was that we need to be MORE democratic, not less – by valuing democracy and not allowing people to tear it down, exactly what I am trying to do now.

Democratic institutions only have as much power as they're given.

In one of our sub projects using Anjin Virtual Computer-

We really are emulating an XR headset inside the Galaxy XR. That hasn't been done before- with a real OS that boots and a stereo passthrough renderer. Can't explain it clearer than that.

Here's another video that shows it. Look closely at the lenses of the virtual XR headset.

>Think about it, it's super easy to, as a manager, do nothing but tell people to work harder, do better, and ask why this isn't done, why this isn't good, etc. This is what being bad at leading a profit maximizing company looks like.

I agree with this 100%. I may add a tidbit here simply because I'm thinking about it. There is a real agency problem in leadership.

I've been a staff engineer[0] for just over half a decade now. I've noticed, particularly in the last few years, there's been more dustups over executive[1] authority of the role. Traditionally, what I've experienced is having latitude to observe, identify, and approach engineering problems that affect multiple teams or systems, for example. I've contributed a great deal to engineering strategy, particularly as it relates to whatever problem domain I am embedded in. Its about helping teams meet their immediate sprint goals, not working on strategy or making sure upcoming work for teams is unblocked by doing platform work etc.

The only thing I can surmise about this shift is that engineering managers (and really managers going up the chain) don't want to feel challenged by a "non manager". They didn't like that we didn't have a usual reporting structure that other ICs do (we all rolled up the same senior director or VP rather than an EM) and previously had similar stature that of a director.

The issue here is that LLM’s are not human and so having a human mental model of how to communicate doesn’t really work. If I communicate to my engineer to do X I know all kinds of things about them, like their coding style, strengths and weaknesses, and that they have some familiarity with the code they are working with and won’t bring the entirety of stack overflow answers to the context we are working in. LLM’s are nothing like this even when working with large amounts of context, they fail in extremely unpredictable ways from one prompt to the next. If you disagree I’d be interested in what stack or prompting you are using that avoids this.

Where I live I am often surrounded by Waymo vehicles... is Lidar 100% safe for people to be around? I ask because I read an article about how Lidar on one of the new Volvos could destroy your phone camera if you pointed it at it? If Lidar can do that to a phone camera, can it hurt your eyes?

Are there any specifics about how this was trained? Especially when 5.1 is only a month old. I'm a little skeptical of benchmarks these days and wish they put this up on llmarena

edit: noticed 5.2 is ranked in the webdev arena (#2 tied with gemini-3.0-pro), but not yet in text arena (last update 22hrs ago)

Optimization takes up time, and often it takes up the time of an expert.

Given that, people need to accept higher costs, longer development times, or reduced scope if they want better optimized games.

But what is worse, is just trying to optimize software is not the same as successfully optimizing it. So time and money spent on optimization might yield no results because there might not be anymore efficiency to be gained, the person doing the work lacks the technical skill, the gains are part of a tradeoff that cannot be justified, or the person doing the work can't make a change (i.e., a 3rd party library is the problem).

The lack of technical skill is a big one, IMO. I'm personally terrible at optimizing code, but I'm pretty good at building functional software in a short amount of time. We have a person on our team who is really good at it and sometimes he'll come in after me to optimize work that I've done. But he'll spend several multiples of the time I took making it work and hammering out edge cases. Sometimes the savings is worth it.

I remember when a bully would have to go up to you themselves to mete out whatever harassment, and you could avoid a lot of it by just being aware and avoiding that particular person.

Juxtapose that with today, where any one bully can create dozens of accounts to bully in a swarm, and the bully has constant access to you from your own pocket. Also, a person in Minsk or Timbuktu or whatever couldn't just come up to your house in the middle of the night to harass you out of boredom.

This "we could do X before computers, why are we trying to ban X-with-computers now?" line of arguments is just intellectually lazy. If a bad behavior was well moderated in the past because it was labor or resource intensive, the sudden removal of those constraints is a material change that demands revisiting. Put another way, if a constraint stops working, we should change constraints, not just do the old constraint with a confused expression on our faces.

I remember about a problem I had while quick testing notcurses. I tried chatGPT which produced a lot of weird but kinda believable statements about the fact that I had to include wchar and define a specific preprocessor macro, AND I had to place the includes for notcurses, other includes and macros in a specific order.

My sentiment was "that's obviously a weird non-intended hack" but I wanted to test quickly, and well ... it worked. Later, reading the man-pages I aknowledged the fact that I needed to declare specific flags for gcc in place of the gpt advised solution.

I think these kind of value based judgements are hard to emulate for LLMs, it's hard for them to identifiate a single source as the most authoritative source in a sea of lesser authoritative (but numerous) sources.

Rivian has a huge interest in being the outsourcer for legacy automakers. They’re not able to sell $100k cars enough and even with the promised R2, they probably will only be a small-ish player in the EV market. Their CEO recognizes how crazy good Chinese EVs are and currently they’re not even a competitor for Tesla.

But, VW is willing to pay $5B for their software platform. I think they want to extend that to being able to sell custom chips and “AI” capabilities, whatever that means.

The first really stupid customer I encountered had a bunch of beanie babies in his office.

I used to mutter about him being that race in Star Trek TNG that kidnaps people to make their ships “go”.

But then one day I had an epiphany. I realized his boss knows exactly what he is. He’s a useful idiot with a knack of getting something for nothing out of people. That’s his skill. Not dinner conversation, but cost control. That and the Gervais Principle explain a lot of our head scratching about bad managers. They just know how to nerdsnipe or neg us into doing free work.

Every time I take a computer to the Genius Bar I impersonate that beautiful moron. I’ve paid for one expensive repair that I feel nobody should have to pay for, but also not paid for two repairs that I knew damned well were out of warranty. All told I’ve paid pretty much what a fair universe should have charged me for lifetime maintenance on my hardware.

The thing is if they know you’re in IT they will engage in a coherent argument with you that explains why they are entitled to deny your claim. If you just say, “it won’t connect to the internet” then they do the mental math on what an argument will cost with this grandpa whose kids bought him too much laptop for his own good and decide a waver is just less work.

I do think there can be element of snobbishness around it, but that's not really the point. The overculture of corporate America has finally overtaken the hackerish (relative) meritocracy of early tech, of Getting Things Done and Building Cool Stuff. Rewards are increasingly tied to metrics decoupled from useful outcomes. If you want to get paid a big tech salary you need to go through the leetcode grind, and do things like project sufficient "masculine energy" (lol). Management performance is measured by hiring and expansion more than product delivery and success. The ethics of what you are doing are completely secondary to shareholder value. You still need technical skills, but they are somewhat less important, there are many more competing incentives than there used to be, and the stakes are higher. This has been happening since the early days - cf. Microserfs, written all the way back in 1995 - it's just that tech has worked its way so thoroughly into the fabric of corporate existence that the two have more or less completely merged.

That "deep dive" is an apples-to-oranges comparison. MCP is also a "HTTP API" that you so criticize.

You also somehow consistently think LLM making tool calls against an OpenAPI spec would result in hallucination, while tool calls are somehow magically exempt from such.

All of this writing sounds like you picked a conclusion and then tried to justify it.

There's no reason an "Agentic OpenAPI" marked as such in a header wouldn't be just as good as MCP and it would save a ton of engineering effort.

Take this all with a grain of salt as it's hearsay:

From what I understand, nobody has done any real scaling since the GPT-4 era. 4.5 was a bit larger than 4, but not as much as the orders of magnitude difference between 3 and 4, and 5 is smaller than 4.5. Google and Anthropic haven't gone substantially bigger than GPT-4 either. Improvements since 4 are almost entirely from reasoning and RL. In 2026 or 2027, we should see a model that uses the current datacenter buildout and actually scales up.

Depends on the type of LIDAR. LIDAR rated for vehicle use is at a wavelength opaque to the eyes so it hits the surface and fluid of your eye and reflects back rather than going through to your cones and rods.

It isn't however opaque for optical glass (since the LIDAR has to shine through optical glass in the first place) so it hits your camera lens, goes straight through, and slams the sensor.

So much fun streaming/sync/cdc stuff happening, all so cool. Having an underlying FUSE driver doing the Change Data Capture is really neat. This looks like such an incredibly lightweight way to remote-connect to sqlite. And to add a sort of exterior transaction management.

Different use case, but makes me think of sqlite Rewrite-it-it-Rust Turso announcing AgentFS. Here the roles are flipped, sqlite is acting as a file store to back FUSE, to allow watching/transaction-managing the filesystem/what agents are doing. Turso also has a sick CDC system built in, that just writes all changes to a cdc table. Which is related to this whole meta question, of what is happening to my sqlite DB. https://turso.tech/blog/agentfs

I'm in the middle and lean loyal, but the younger folks probably got it right. There's no more IBM of the 1960s loyalty to be had from the company's perspective, so why not go out and make what you can while you can. No more pensions, not even a gold watch. Look at how often tech sees layoffs - it's not if there's another, it's when.

Which is the better option now. But the one he's talking about is the OG windows phone swipe keyboard which would predict next word almost like from a LLM these days. For that reason, you can swipe like a maniac but it'd still type the correct thing.

Apple keyboard is shit. Swype (the one Microsoft bought) is better but still shit. Gboard is ok. But none of them are close to that windows phone keyboard. I still miss it.

As someone with 700 hours in the game, I've played the game both on Windows and Linux.

A lot of issues are to do with the fact that the game seems to corrupt itself. If I have issues (usually performance related), I do a steam integrity check and I have zero issues afterwards. BTW, I've had to do this on several games now, so this isn't something that is unique to HellDivers. My hardware is good BTW, I check in various utils and the drives are "ok" as far as I can tell.

> - To their PC not reboot and BSOD (was a case few months ago)

This was hyped up by a few big YouTubers. The BSODs was because their PCs were broken. One literally had a burn mark on their processor (a known issue with some boards/processor combos) and the BSODs went away when they replaced their processor. This tells me that there was something wrong with their PC and any game would have caused a BSOD.

So I am extremely sceptical of any claims of BSODs because of a game. What almost is always the case is that the OS or the hardware is at issue and playing a game will trigger the issue.

If you are experiencing BSODs I would make sure your hardware and OS are actually good, because they are probably not. BTW I haven't a BSOD in Windows for about a decade because I don't buy crap hardware.

> - Be able to actually finish a mission (game still crashes a lot just after extraction, it's still rare for the full team to survive 3 missions in a row)

False. A few months ago I played it for an entire day and the game was fine. Last week I played it a good portion of Saturday night. I'm in several large HellDivers focused Discord servers and I've not heard a lot of people complaining about it. Maybe 6 months ago or a year ago this was the case, but not now.

> Be able to use weapon customisation (the game crashed, when you navigated to the page with custom paints)

This happened for like about a week for some people and I personally didn't experience this.

> To not issue stim/reload/weapon change multiple times, for them just to work (it's still normal to press stim 6 times in some cases, before it activates, without any real reason)

I've not experience this. Not heard anyone complain about this and I am in like 4 different HellDivers focus'd discord servers

> Not be attacked by enemies that faze through buildings

This can be annoying, but it happens like once in a while. It isn't the end of the world.

My browser integrates an LLM, so I asked it to restate the headline of this one, and it came up with "Developer Suspended by Google After Uploading AI Dataset Containing CSAM" which seems pretty even-handed. Of course, I would want to dial the snark to 11. Many hacker stories can be headlined "Developer discovers that C still sucks" etc.

OK, I can follow WET before you DRY, to me that's just a non-zealous version of Don't Repeat Yourself.

I think, if you're writing code where you know the entire code base, a lot of the clean principles seem less important, but once you get someone who doesn't, and that can be you coming back to the project in three months, suddenly they have value.

Hacker News is almost indistinguishable in spirit from a well-run subreddit. Reddit is not centered on user profiles and followers and yet, Reddit is included in the Australia's social media ban.

It is clear from the ruling that by including YouTube, Reddit and Facebook, they take a broad definition of what social media is, essentially anything with user interaction and Hacker News definitely fits the bill.

And if your criteria includes "social aspects like user profiles and followers", then GitHub would fit too: it has user profiles, followers / stars, and allows for discussion. It is even included in the "social media" list for ESTA and visa applications for the US. We could even include StackOverflow, I mean, it used to be common practice to build a profile, chasing a reputation score so that you could show off to recruiters.

I in no way want to underplay the seriousness of child sexual abuse, but as a naturist I find all this paranoia around nudity and “not safe for work” to be somewhere between hilarious and bewildering. Normal is what you grew up with I guess, and I come from an FKK family. What’s so shocking about a human being? All that stuff in public speaking about “imagine your audience is naked”. Yeah, fine: so what’s Plan B?

> I can be there to take him to the hospital, talk to him about it, etc.

Nanny state! Let him take himself to medical facilities, and deal with the consequences himself instead of interfering

HELL Let's ban hospitals, they're just interfering in the natural order of life.

Real talk: I know that those are strawmen and you most definitely think that where you draw the line is right for you and your family (assuming that you have one), but the reality is that the line gets moved a LOT as children grow - your line might be great if you have developed a good relationship with your son, and he's received a good social education from his friends/network and he's over a certain age.

It fails very quickly if he's, say, 5 years old and/or he's had no friends that model good/bad behaviour and/or you and he are human meaning that communication, interpretation, and any hint of resentment lies underneath (keep in mind that teenagers are geared to fight/be angry/dislike their parents, for the specific reason that it motivates them to leave home and begin their own lives)

Not really:

GitHub - Historically, GitHub reports uptime around 99.95% or higher, which translates to roughly 20–25 minutes of downtime per month. They have a large infrastructure and redundancy, so outages are rare but can happen during major incidents.

GitLab - GitLab also targets 99.95% uptime for its SaaS offering (GitLab.com). However, GitLab has had slightly more frequent service disruptions compared to GitHub in the past, especially during scaling events or major upgrades. For self-hosted GitLab instances, uptime depends heavily on your own infrastructure.

That's never been my stance because there's a difference between mass surveillance and targeted surveillance. If you understood that then you wouldn't be getting lost and making silly references to "God".

I don't believe that the NSA is omniscient. I believe they have 95% of data on 95% of the population through mass surveillance, and 99.9% of data on 99.9% of people of interest through targeted surveillance.

You think abusing public CAs for mass surveillance is a genius idea, and that its lack of real-world abuse proves that mass surveillance just doesn't happen - full stop.

Unfortunately you fail to consider that if they tried to do this just once, they would be detected immediately, offending CAs would be quickly removed from every OS and browser on the planet, the trust in our digital infrastructure would be eroded, impacting the economy, and it would likely all be in exchange for nothing.

On the other hand if you're trying to target someone then what's the point of using an attack that immediately tips off your target, that requires them to be on a network path that you control, and that's trivially defeated if they simply use a VPN or any sort of application-layer encryption, like Signal? There is none.

Yes the article is very meandering. But near the end he mentions that the chips nvidia sold last three quarters alone would require about 15GW of electricity to actually run. But where are all the datacenters? And how long can this go on?

When the ground truth is someone keeps buying zillions worth of equipment from investors' money, but the chances to use it are slim, not to even mention getting some profit off it, there just has to be some fraud involved. Probably not on nvidia's side, but would not bet on it.

Diffusion large language models (dLLMs) promise things that autoregressive LLMs cannot: parallel decoding, error correction, and random-order generation. Over the past year, a wave of papers has pushed this vision, and closed-source systems like Gemini Diffusion and Mercury report impressive throughput numbers. In this blog, we take a step back and ask a simple question: if we look at both speed and accuracy together, are diffusion LLMs actually better decoders than strong autoregressive (AR) models?

In our study of open-source systems, we find a consistent accuracy–parallelism trade-off: pushing more tokens per forward pass almost always costs accuracy. We introduce Accuracy Under Parallelism (AUP), a hardware-robust metric that scores this trade-off in one number, and we present d3LLM, a distillation + decoding framework that improves AUP and narrows the gap to strong AR + speculative decoding baselines. Our d3LLM achieves up to 5× speedup over the AR baseline (Qwen-2.5-7B-it) on H100 GPU and 3.5× speedup on A100 GPU.

That's why I mentioned the assumption about the velocity distribution. Sure, the velocities aren't Maxwell-Boltzmann, but that doesn't matter too much for getting a sense of the scale of the issue. The way an astrophysicist thinks (I am one) is that if we make generous assumptions and it turns out to not be a problem, then it definitely isn't a problem. Here they have determined it might be a problem, so further study is warranted. It's also a scientist strategy to publish something slightly wrong to encourage more citations.

I swear the android autocorrect got so much worse at some point. Somewhere between 5 and 15 years ago. I used to be able to type vaguely coherent sentences and all of the typos would magically become the words I meant, even if they didn't look right. Now I frequently type completely correct sentences and the correctly spelled words get changed into other words that make no sense in context.

And i used to be able to backspace the wrong word and fix it and it would learn thats what I meant. Now if I try that, it'll frequently keep trying to edit to the word I didn't mean unless I press the little checkmark in the autocorrect panel. Just annoying UX.
