Speaking as someone who has been using HMDs since '05, and periodically checks in on dynamic foveated rendering every year or so, the frustrating thing is that sensitivity to it varies significantly.

Some folks experience the image pretty much continuously and don't notice the edge blurring. Others see it every time they move their eyes left/right. This is on the same headset.

Part of it is driven by differences in eye geometry, and even color (as this impacts the effectiveness of the camera track of the eyes). I've seen the raw camera buffers for eye track on a couple headsets and they're.. a mess.

Honestly that the feature works at all, for anyone, is still mind boggling to me.

I wonder if there are still undergraduate CS programs that use a functional programming language in the intro course? MIT switched away from SICP (Scheme) to Python back in the late 2000s, and Berkeley switched away from Scheme sometime afterwards. Shriram Krishnamurthi has heavily promoted Racket in education and continues to do so, but for introductory CS he has moved on to Pyret, which has Algol-like syntax as opposed to S-expressions and doesn’t require programmers to think in terms of functional programming; for example, Pyret has loops and mutable variables.

At my institution (Ohlone College in Fremont, California), we teach the intro courses in C++. However, for discrete math, a sophomore-level course, each instructor is allowed to choose the language. I chose Haskell the last time I taught the class, and I plan to use Haskell again, since I believe it’s a great vehicle for coding discrete math, plus I believe it’s a great thing teaching undergraduates functional programming early on.

They understand things the first time. I remember taking calculus in university and hitting my head against the wall because I couldn't understand the concepts.

This kid and his cohorts, they hear a concept for the first time, and they just get it. Then when it comes to doing the problems, he might struggle a little but then he gets it. He is getting 95% in calculus and the only reason he lost marks is because he made sloppy mistakes.

I agree it's hard to get things into orbit. The question is if it's harder than solving the DC capacity problems here on Earth.

In the 1950s everyone thought we were entering the atomic age, an era when electricity would be too cheap to meter. That didn't happen: making nuclear simultaneously safe and cheap turned out to be much harder than anyone anticipated. Eventually people gave up on the Age Of Atoms and started saying that solar and wind were better. Go back in time and try to sell that in the 1950s and everyone would have thought you were insane. Huge land consumption and it only works intermittently? Why would that ever be easier than building a quick reactor?

And so here we are in 2026. The track record of SpaceX making things quickly and cheaply is vastly better than the modern nuclear industry. That's not necessarily the industries fault, but the over-regulation issue is real. If datacenters have the same problem Musk can still win despite the huge starting handicap. And everyone I know with experience of datacenter construction has similar stories. 90% of it is about dealing with governments and electricity suppliers (but that's mostly the grid, which is the government again).

The main point is logging in to the fake profile does not do anything different from logging in to the main profile. If you image the whole thing and somehow completely bypass secure enclave (but let's assume you can't actually bruteforce the PIN because it's not feasible) then you enter the distress PIN in controlled environment and you look at what writes/reads it does and to where, even then you would not be able to tell you are in the fake profile. Nothing gets deleted eagerly, just the act of logging in is destructive to overlapping profiles. This is the only different thing in the main profile. It know which data belongs to fallback profile and will not allocate anything in those blocks. However it's possible to set up the device without fallback profile so you don't know if you are in the fallback profile or just on device without one set up.

Hopefully I explained it clearly. I haven't seen this idea anywhere else so I would be curious if someone smarter actually tried something like that already.

> Democrats turned on Elon during covid, as he was against lockdowns. This spread into wide distrust and complete sidelining and antagonism towards tech during the Biden administration. You can hear about it from Ben and Marc on their a16z podcast, when they explained why they are endorsing Trump.

Look, a16z basically are talking their book. They went heavily into crypto, and when the Biden administration started taking actions against crypto, they started supporting Republicans.

Not everything needs to be complicated.

Show HN: A package manager for agent skills with built-in evals
by guypod | 2026-02-05 15:45:44+00:00
I'm Guy, the founder behind Snyk — now building Tessl, a package manager for agent skills.

We’ve recently witnessed that most teams still treat skills as static artifacts: markdown files, created or copied from repo to repo.

This approach offers a strong initial boost, but quickly creates debt:

- Skills are duplicated, and updates never roll out.
- Poor quality skills go unseen, misguiding agents instead of helping.
- Skill knowledge grows stale, and don’t keep up with the systems and practices they describe.

Without a way to evaluate skills, teams have no clear way to understand how good a skill actually is, or if it degraded over time.

Our belief is that evaluations are the foundation for having quality skills.

With that in mind, I’m glad to announce that Tessl Registry contains review evals for over 2,000 skills, and you can request an evaluation for any public skill.

Super excited to be launching this — keen to get your feedback, and looking forward to the many more enhancements in the queue!

But this time is different! For reasons!

Yea, the more things change the more they stay the same. This latest AI hype cycle seems to be no different. Which I think will become more widely accepted over the next couple of years as creating deployable, production-ready, maintainable, sellable, profitable software remains difficult for all the reasons besides the hands-to-keyboard writing of code.

>Why is it possible for a running application to read information stored by so many other applications which are not related to the program in question?

This question has been answered a million times, and thousands of times on HN alone.

Because in a desktop operating system the vast majority of people using their computer want to open files, they do that so applications can share information.

>Why is isolation between applications not in place by default?

This is mostly how phones work. The thing is the phone OS makes for a sucky platform for getting things done.

> Operating systems are supposed to get in the way

Operating systems that get in the way get one of two things. All their security settings disabled by the user (See Windows Vista) or not used by users.

Security and usage are at odds with each other. You have locks on your house right? Do you have locks on each of your cabinets? Your refrigerator? Your sock drawer?

Again, phones are one of the non-legacy places where there is far more security and files are kept in applications for the most part, bug they make terrible development platforms.

I checked way back machine and they have been making large changes to that page every day for the last month. It used to be a lie that office 365 was rename to office 365 copilot, yet it is an app with only chat bot functionality. They advertise the copilot integration for the main office apps now, but those are not part of the copilot app they are trying to trick you into installing.

Also very subject to wildly unstable market dynamics. If it's profitable to mine, they'll want as much capacity as they can get, leading Hetzner to over provision. Then once it becomes unprofitable, they'll want to stop all mining, leaving a ton of idle, unpaid machines. Better to have stable customers that don't swing 0-100 utilization depending on ability to arbitrage compute costs.

I wouldn't be surprised if mining is also associated with fraud (e.g. using stolen credit cards to buy compute).

Sure, the problem with Kiwi Farms is that people "disprove of them", not what they disprove of. KF were even blocked by CloudFlare, who have a very strong neutrality policy, that's how toxic, hateful and illegal they were.

You, my friend, are profoundly gifted, especially if you scored that high as an adult. That said, it only describes how your brain works, it doesn't describe how high achieving you will be. That is an amalgamation of all your life experiences and things like opportunity, perseverance, etc. The tools you have to understand complex things are much wider than a regular person, but it doesn't mean a regular person can't outhustle you. I don't know how old you are, but it's never to late to dust off your tools and give it a go at something more aspirational, if that's something you've always wanted to do. If you're happy as you are, then there's no point because happiness is what really matters in the end.

This has just had a major update to include other renewables (eg hydro, solar) as well as non-renewable energy sources (gas).

It’s also added grid boundaries and cabling recently - and I think there’s also wind roses planned?

My one UI wish - the energy sources filters are currently displayed as options on the map - rather than controls for the entire UI - which meant I missed them entirely at first. Would be great if they could be given more prominence.

The problem was always the platform. For me, I saw very early on that kubernetes was exactly what I wanted after reading about how Google "treats the datacenter like one large computer." And I've been very happily running my own side projects on my own home cluster for 10 ish years (my kube-system namespace is 9y old). But selling any of my employers on this was a very hard proposition until enough people had shown it working at that scale.

Hah, kill three birds with one stone? The satellites double up as propellant depots for other space missions, that just happen to have GPUs inside? And maybe use droplet radiators to expel the low grade heat from the propellant. I wonder if that can be made safe at all. They use propellant to cool the engine skins so... maybe?

The parent's point seems to be that since most voters of both corporate parties have pretty much universally internalized and accepted they're voting for the "lesser of two evils," it's safe to conclude our political system is captured and has been for decades. Furthermore, 1/3 of people refusing to vote is not solely out of laziness. Many of them have concluded the system is FUBAR.

We're given two shit options which come about through a broken primary process and is reported on by monopolistic media. The news media and social media is siloed in such a way that people filter into one of two corporation-approved spheres of groupthink. These two spheres manufacture consent for each other in numerous ways, one of which is exemplified above. The good cop/bad cop setup makes it look like things are constantly getting broken only to have the illusion of being re-fixed by the other group, as measured by a pre-approved narratives that are disseminated.

The COVID pandemic is another great example. Sadly the CDC has been a disgrace under all recent administrations of both parties and has lots of blood on its hands:

https://www.thegauntlet.news/p/how-the-press-manufactured-co...

Unfortunately the WHO has similar issues:

https://old.reddit.com/r/ZeroCovidCommunity/comments/1q87aki...

Almost as if capital interests are running the show. But what are we fighting about in 2026? That's right, whether we should or should not be affiliated with the WHO, and to what extent our CDC should be funded. Two broken institutions and a performative fight about them. Meanwhile millions have/will see their grave earlier than they otherwise would have, thanks to long COVID (many of whom will never even make that connection, including their doctors who were spoonfed the "vax and relax" / "back to normal" messaging in service to an archaic consumption-based economy.

> discriminating against someone in their 50s (even 59)

I am in my 50's and I think the biggest discrimination I notice is not specifically age-related but cost-related. I am very expensive, a recent grad is not. Lots of companies think (some are right) that they can do well with the recent grads and are unwilling to shell out what it costs to hire me.

I doubt obsolescence anticipation has anything to do with it. That’s how tech enthusiasts think, but most people think more in terms of, “Is this useful to me?” And if it’s doing a useful thing now then it should still be doing that useful thing next year as long as nobody fucks with it.

I would guess it’s more just consumer fatigue. For two reasons. First, AI’s still at the “all bark and no bite” phase of the hype cycle, and most people don’t enjoy trying a bunch of things just to figure out if they work as advertised. Where early adopters think of that as play time, typical consumers see it as wasted time. Second, and perhaps even worse, they have learned that they can’t trust that à product will still be doing that useful thing in the future because the tech enthusiasts who make these products can’t resist the urge to keep fucking with it.

If we're talking Thatcher's policies some bangers that people for some reason never bring up, she is also responsible for:

* Countless (they literally didn't bother to count) deaths caused because she refused to release accurate guidance during the height of the HIV epidemic, she didn't want the public knowing about sexual acts she disapproved of.

* Countless (again) STDs, rape, child abuse and suicide cases because she made it illegal for teachers to inform nor support students about LGBTQ issues. The average LGBTQ teenager who finished school before 2003 received ZERO sexual education catered to their actual needs, and ZERO support for the bullying they would be receiving.

I think in general people demonise her rightly, because in 2026 she would be seen as a vicious monster of a person. It is not enough to just be really great for free trade in the current era, we are beyond the point that we have to settle for unhinged backwards politics just for that.

Great that you are open to feedback! I wish every blogger could hear and internalize this but I'm just a lowly HN poster with no reach, so I'll just piss into the wind here:

You're probably a really good writer, and when you are a good writer, people want to hear your authentic voice. When an author uses AI, even "just a little to clean things up" it taints the whole piece. It's like they farted in the room. Everyone can smell it and everyone knows they did it. When I'm half way through an article and I smell it, I kind of just give up in disgust. If I wanted to hear what an LLM thought about a topic, I'd just ask an LLM--they are very accessible now. We go to HN and read blogs and articles because we want to hear what a human thinks about it.

I worked on an early spreadsheet and word-processing system at Lehman Brothers back in about 1984. The system was called Jacquard.
The investment bankers built comparative financials in this system and printed them out on 14x11 folded paper.
The deal was that you could enter formulas into a bar, with a formula for each column, and drag the bar down to apply the formula to the cells.

You should consider medication. I used to be against medication, but after talking with a few of my friends who have gifted children, things like ADHD are extremely common. Avoiding medication and letting them spin in the wind is not a good strategy and it destroys their self esteem. Get as small a dose as possible and then wean him off as he gets older and hopefully his prefrontal cortex will catch up and help regulate him.

I have been thinking of something similar for quite some time. Though my idea was more like making comments "first class citizens", and in certain formats they can link to each other/external documents, tracking inconsistent changes.

This might also extend to runtime checks (e.g. some business invariant in the form of an assert that has such a "dependency-tracked" comment)

Maybe saying something like this would make things clearer:

> His directed intention was to disrupt communication. He did not explicitly target EMS calls, however, his actions impacted EMS communications because of his intentions to disrupt communications.

Example:

If I poison the water for a city, my directed intention may be, "to lower pollution in the region". I am not specifically targeting children, however, a consequence of my intentions of poisoning the water will cause the death of children.

This fellow intentionally took a disruptive action. The consequences of those directed disruptions may have caused (had caused?) catastrophic consequences - that is part of why what he did was illegal. In breaking that law, he became culpable for the outcome for all of the harm caused, targeted or otherwise. Ultimately, it was an intention which presupposed, "My personal opinion supersedes all others." It's an self-centered obscenity without regard to others.

Droplet radiators can theoretically do this. The radiator is made up of extremely fine liquid droplets expelled from what is basically a big space shower head. The droplet cloud has a big surface area so more heat can radiate. The droplets are collected in a sort of drain the other side. The idea has been around for decades but there are lots of practical problems to work out, like minimizing losses due to splashes or droplets heading in the wrong direction (e.g. using ferrofluids and magnetic containment). It's never been worked on seriously because conventional radiators were always enough.

With droplet radiators increasing the effective size means using a bigger head/drain and longer booms to expand the distance between them, so the scaling properties are different to pipe based radiators.

Oh no! You have found the fatal flaw of using paper currency backed by anything. Before 1913 money was gold and silver. Not paper bills backed by those metals.

Many people doubt that returning to gold and silver coinage is possible. Going to gold backed currency is a step in the right direction.

A full reserve requirement might work for paper currency. But the only way the plebs that are stuck with paper can truly secure their wealth is to use metal the same as countries do.
Show HN: DeepBrainz-R1 – Reasoning-First Small Models for Agentic Systems
by DeepBrainz | 2026-02-05 15:51:54+00:00
Hi HN,

I’m releasing DeepBrainz-R1 — a family of reasoning-first Small Language Models (SLMs) designed for agentic systems in production.

The core idea is simple: agentic systems don’t ask once — they reason repeatedly (tool calls, verification loops, retries, schema-constrained outputs). That changes reliability and cost requirements, where large chat-optimized LLMs often struggle.

DeepBrainz-R1 models are post-trained to improve multi-step reasoning behavior, output stability, and robustness under agentic workloads. The focus is not chat or creative writing, but predictable reasoning at small parameter sizes.

Models:
- R1-4B (flagship)
- R1-2B (lower latency / cost)
- R1-0.6B-v2 (small, local / edge agents)
- Experimental long-context variants (16K / 40K)

Everything is open (Apache-2.0). Community-maintained quantizations (GGUF, low-bit) are already appearing.

I’d love feedback from people building agents, tool-using systems, or long-running reasoning pipelines.
