AED - Automated External Defibrillator. They're portable device defibrillator which can deliver an electric shock. As I understand it, it detects an abnormal heart rhythm and shocks the rhythm back to normal. Note that there are some situations where they will not work. (For example, Pulseless Electrical Activity or PEA is "non-shockable.")

Well yeah, if you have one senior with the power of 2-3 AI agents - you don’t need juniors or sometimes mid developers at all. Let’s say you’re Whatsapp and your 20 people develop the app, well now you need 5 at most for the same workload.

Obviously we’re not yet at the point where the CEO can enter “build me the next Uber” in Claude Code and watch the stock price go up.

They tried, but the Europeans Mafias know that if the violence hits the fan and craps out civilians (non-gang related members), these would be crushed down in miliseconds.

The CNI is no joke and it has -ahem- nonstandard methods to deal with these scum. Spain has grown a huge counterterrorism wisdom over decades.

Best one I know of as a direct replacement is AWS PALACE: https://awslabs.github.io/palace/stable/

Of course, you have to interact with the solver through JSON files and provide your own initial mesh. They recently added adaptive refinement but I don't know how well it works. Given what Ansys charges for an HFSS seat though can't complain!

Most people don't actually know anything about any of this. If they've heard of RCV at all their understanding of it is at the level of "it's something different than the status quo and supposedly better". You could swap in STAR and they mostly wouldn't even notice that you've changed anything. But you'd notice the difference in the election outcomes, in a good way.

Correct. SaaS is a business model, not a technical concept. But the real problem is that there is no equivalent business model for selling local first software. Traditional desktop apps were single purchase items. Local first is not because you just navigate to a website in your browser and blammo you get the software. What we need is a way to make money off of local first software.

This is a naive perspective. In reality, most of the software development that a typical growth company does is eligible. As one of CRA’s auditors once told me, “The general arc of your development has to meet the criteria of being technically challenging and uncertain, and you have to follow a generally scientific approach, measuring your results empirically. But if you need a web console to help with that, who are we to say that’s not eligible support work?”

Why go through the stress and performative dance of a poly when there's zero upside? He admitted to being a friend and (according to the article) that's alone enough to demote and block advancement.

Polys are also subjective. They keep asking the same questions over and over again until there's some indication they can point to and say you're lying. It might be a sneeze, cough, or a deep breath at the wrong time. It's also generally a multi hour to multi day ordeal. I wouldn't bother if I was them.
Show HN: Distapp. Manage and distribute Android, iOS and Desktop app
by yunusefendi52 | 2025-07-05 18:24:23+00:00
Hi HN,

I built DistApp, a tool for managing and distributing Android, iOS, and Desktop app builds. I created it after App Center Distribution was discontinued, I wanted a way to easily share builds with the QA team and users with different groups.

DistApp lets you manage multiple apps across different organizations and groups. It also supports self-hosting on your own infrastructure and is open-source https://github.com/yunusefendi52/distapp

You can try the free version by signing in with your Google account. I chose not to support email/password accounts to reduce abuse on the free version. But I’m open to suggestions if you think there’s a better way :)

Thank you

The primary use case for AI-in-the-box is a superhuman CEO that sees everything and makes no mistakes. As an investor you can be sure that your money are multiplying at the highest rate possible. However as a self-serving investor you also want your CEO to side-step any laws and ethics that stand in your way, unless ignoring those laws will bring more trouble than profit. All that while maintaining a facade of selfless philanthropist for the public. For a reasonable price, your AI CEO will be fine-tuned to serve your goals perfectly.

Remember that fine-tuning a well-behaved AI to do something as simple as writing malware in C++ makes widespread changes in the AI and turns it into a monstrosity. There was an HN post about this recently: fine-tuning an aligned model produces broadly misaligned results. So what do you think will happen when our AI CEO gets fine-tuned to prioritize shareholder interests over public interests?

Interviewing is a skill. I think that he got really good at it, both in tailor his CV as well as the process itself. It probably worked on the process and make adjustments. Based on the what I’ve read, it seems that he was interviewing all the time.

So, IMHO, he focused in the interview process over everything else, including understanding and exploiting the blind spots. He iterated and refined it, until, he became a master of it.

He really seemed to be not great at the work itself, though. He was being fired after a couple of days, which I don’t think is common. You really have to do it very badly to be fired so quick after being hired.

The reason it's easier to scale local software is that it does not rely on cloud resources. As a result it's cheaper for a startup to distribute local first software since they don't need the infrastructure of a traditional cloud app. The problem is there is no business model for local first software like there is for subscriptions with SaaS. Traditional desktop apps were sold as single purchase items on CDs. That just doesn't work for local first software, since you probably just navigate to a website to get the software.

In what way do you consider CoW to be an efficiency gain? Traditionally, it is considered more expensive due to write amplification. In place filesystems such as XFS tend to be more efficient in terms of IOPs and CoW filesystems need to do many tricks to be close to them.

As for ensuring data integrity, I cannot talk about other CoW filesystems, but ZFS has an atomic transaction commit that relies on CoW. In ZFS, your changes either happened or they did not happen. The entire file system is a giant merkle tree and every change requires that all nodes of the tree up to the root be rewritten. To minimize the penalty of CoW, these changes are aggregated into transaction groups that are then committed atomically. Thus, you simultaneously have both the old and new versions available, plus possible more than just 1 old version. ZFS will start recycling space after a couple transaction group commits, but often, you can go further back in its history if needed after some catastrophic event, although ZFS makes no solid guarantee of this (until you fiddle with module parameter settings to prevent reclaim from being so aggressive).

If it counts for anything, I have hundreds of commits in OpenZFS, so I am fairly familiar with how ZFS works internally.

I suppose it takes living in both countries to really just whether Canada is “much” more socialist. The US has a lot of socialism in the form of generous disability income replacement programs, Medicare and Medicaid, SNAP, and the like. Canadian provinces must implement a single payor medical insurance program within certain parameters, but dentistry - bar a very new and very small federal program - is fully private. And pharmaceutical pricing is largely free market.

When you zoom in on some of the Big Beautiful Bill’s new programs, they appear more “socialist” than anything Canadians have ever enjoyed.

One of the biggest challenges in RAG Evaluation is the assumption that you somehow can get the "source of truth" generated, specifically the set of "golden answers" (or golden chunks/documents). In practice that is extremely difficult and non scalable. Open-RAG-Eval is a new open source project that aims to address that via reference-free evaluation such as UMBRELA and AutoNuggetizer scores.

Repo: https://github.com/vectara/open-rag-eval and a nice UI to use this with: openevaluation.ai

Would love to hear feedback on this after you try it out and what you might want to see on the roadmap.

> A sudden cardiac death is the disease equivalent of homicide or a car crash death. It meant someone’s father or husband, wife or mother, was suddenly ripped away without warning.

Now ever increasing numbers of people avoid an abrupt death and live long enough that misery and terrible quality of life extend for decades. Hooray for all of those who emphasize preventing death above all else, whether they are motivated by extracting medical fees during life's long slow twilight, or by more pure considerations.

The authors rely on themselves, not other people. The developers of local first software take on the responsibility of making sure the app runs entirely on local resources. That's not the job of anybody else, and you don't need to pay for it like you do with cloud resources. This means it's cheaper for a startup to distribute local first software. The trick is that it's much harder to get paid for the app.

Adding "invisible" text in a paper seems clearly fraudulent. I don't buy the argument that it is just to catch reviewers using AI, not when the text tells the AI to give positive reviews. In my opinion we should invoke the usual procedures for academic fraud, the same if the author had fabricated data or bribed reviewers. At least make public the redaction of the paper and hope their career ends there

My question is this - once you achieve AGI, what moat do you have, purely on the scientific part? Other than making the AGI even more intelligent.

I see a lot of talk that the first company that achieves AGI, will also achieve market dominance. All other players will crumble. But surely when someone achieves AGI, their competitors will in all likelihood be following closely after. And once those achieve AGI, academia will follow.

Point is, at some point AGI itself will become available the everyone. The only things that will be out of reach for most, is compute - and probably other expensive things on the infrastructure part.

Current AI funding seems to revolve around some sort of winner-take-all scenario. Just keep throwing incredible amounts of money at it, and hope that you've picked the winner. I'm just wondering what the outcome will be if this thesis turns out wrong.

I'm sure I'm missing a lot, but the paper is proposing CRDTs (Conflict-free Replicated Data Types) as the way to get all seven checkmarks. That is fundamentally a distributed solution, not a centralized one (since you don't need CRDTs if you have a central server).

And while they spend a lot of time on CRDTs as a technical solution, I didn't see any suggestions for business model solutions.

In fact, if we had a business model solution--particularly one where your data is not tied to a specific cloud-vendor--then decentralization would not be needed.

I get that they are trying to solve multiple problems with CDRTs (such a latency and offline support) but in my experience (we did this with Groove in the early 2000s) the trade-offs are too big for average users.

Tech has improved since then, of course, so maybe it will work this time.

I’m glad you enjoyed it, though I personally really only contributed shared code - SOE ended up using my UI library from Planetside across all their titles at the time.

From where I sat (St Louis, then San Diego), it looked like the SWG team (Austin) worked incredibly hard on the title, and explored ideas that were really groundbreaking for the time.

The Star Wars universe is a hard one to make into an MMO - the way Jedi work in the universe combined with what players want for themselves is very hard to solve for. I recall Raph wrote about it, maybe more than once.

I think it depends what your typing speed target is, probably. Even for someone who's got a lot of experience, I think it's easy to get bottlenecked on typing speed when it's not a specific focus. Speaking from personal experience, I've been programming for 20ish years and up until a couple months ago my typing speed was probably 90WPM. I recently started practicing intentionally and it's now up to an average of 125ish. If I were interviewing someone and their typing speed was like 60WPM as an experienced dev then that might be a little bit of a red flag. But with auto complete and whatnot, I think it's pretty easy to be at a solid 70 - 90 and still be a very solid dev, and what you get after that is mostly leaning on autocompletion less and being able to spit out some of those idioms a bit faster than you could copy/paste or fill out a snippet.

But possibly to your point, what I am is a passionate _thinker_. I'll take pretty much any opportunity to get away from the computer and do things in my head instead because I find that it's generally faster. If I were someone who liked to prototype "on paper" then I might've been a much faster typist long ago.

Of course they are. Why would you want revenue? If you show revenue, people will ask 'HOW MUCH?' and it will never be enough. The company that was the 100xer, the 1000xer is suddenly the 2x dog. But if you have NO revenue, you can say you're pre-revenue! You're a potential pure play... It's not about how much you earn, it's about how much you're worth. And who is worth the most? Companies that lose money!

I will do the same. I am aligned with ESR basically, as expressed in "The Clue Train Manifesto."

Use value of OSS remains high. Because of that, when I can add to the body of OSS, I do. People will do what they do.

All I control is me. They do them.

We all benefit from the high use value.

I do wish those who have made fortunes would contribute more and keep their roots, and the labor of many high quality humans just a bit more firmly in mind.

Love it! I've been thinking about this a lot lately. It's crazy how many great FOSS alternatives are out there to everything – and while they might be relatively easy to install for tech-people ("docker compose up"), they are still out of reach for non-tech people.

Also, so many of these selfhostable apps are web applications with a db, server and frontend, but for a lot of use cases (at least for me personally) you just use it on one machine and don't even need a "hosted" version or any kind of sync to another device. A completely local desktop program would suffice. For example I do personal accounting once a month on my computer – no need to have a web app running 24/7 somewhere else. I want to turn on the program, do my work, and then turn it off. While I can achieve that easily as a developer, most of the people can't. There seems to be a huge misalignment (for lack of a better word) between the amount of high-quality selfhostable FOSS alternatives and the amount of people that can actually use them. I think we need more projects like yours, where the goal is to close that gap.

I will definitely try to use selfhostblocks for a few things and try to contribute, keep it up!

The depends on how you implement it.

You could also just don't allow to deduct taxes on the work out into digging out the gold.

In the end I do not care. But i feel like people would be equally ignorant if it was proposed to tax the software in other ways (eg VAT on the derived services from operating).

Regardless, these are the discussions to have.

SaaS is a business model. Cloud is DRM. If you run the software in the cloud it can't be pirated and there is perfect lock-in. Double if the data can't be exported.

Related: I've been incubating an idea for a while that open source, as it presently stands, is largely an ecosystem that exists in support of cloud SaaS. This is quite paradoxical because cloud SaaS is by far the least free model for software -- far, far less free than closed source commercial local software.

Large file writes are an exception in ZFS. They are broken into multiple transactions, which can go into multiple transaction groups, such that the updates are not ACID. You can see this in the code here:

https://github.com/openzfs/zfs/blob/6af8db61b1ea489ade2d5344...

Small writes on ZFS are ACID. If ZFS made large writes ACID, large writes could block the transaction group commit for arbitrarily long periods, which is why it does not. Just imagine writing a 1PB file. It would likely take a long time (days?) and it is just not reasonable to block the transaction group commit until it finishes.

That said, for your example, you will often have all of the writes go into the same transaction group commit, such that it becomes ACID, but this is not a strict guarantee. The maximum atomic write size on ZFS is 32MB, assuming alignment. If the write is not aligned to the record size, it will be smaller, as per:

https://github.com/openzfs/zfs/blob/6af8db61b1ea489ade2d5344...

Your method is how I treated pain and it served me well for many years (including broken ankle, countless elbow/wrist/finger injuries), as soon as I could I started movement again, and for tendon injuries even decent intensity seemed to help trigger healing.

That all changed when I tore my achilles, the pain/recovery/etc. process had me doubting everything I knew about recovery and now 14 months later I still question if it needs more rest or more activity or the whole thing is in my head. Ankle/foot injuries seem to have an entirely different approach because standing and walking are so fundamental that you might overdo it just by deciding to make eggs or something.

Lets pray that the ESA fund this properly this time.

Europe need an independent manned access to Space and the time is now:

- Soyuz is old and under-funded. And the Ukraine war destroyed any hope of serious partnership between Europe and Roscosmos for the next 15y.

- Nasa budget is shredded in pieces and hoping any serious scientific collaboration with the current White House banana team is completely delusional.

- China plays solo for its space program. Any serious collaboration for launchers / spacecraft is unlikely.

- Japan is in the same stupid situation than Europe.

In brief: We need something a Made in Europe. More than ever.

I've been using the n-back protocol for over a year and it's definitely improved my cognitive abilities. I don't know if my IQ has increased, but on days where I use this protocol(20-25 minutes) I see a marked improvement in the clarity and vibrancy of my thoughts- put another way this protocol's biggest benefit is it's effectiveness in clearing the mental fog in my head. I've tried experimenting with other protocols(solving crossword/chess puzzles, meditation,etc..)but they were not nearly as effective as n-back.

I've actually built my own variation of n-back(triple n-back), where you're tested on the colour of the stimulus in addition to the sound and position-so it's much more cognitively demanding. If you're interested, you can check it out here: https://mind-workout.pages.dev

That doesn't look like something made in bad faith to me, given that we're seeing threats of precisely that from the usa president [1]. Unfortunately, it's hard to conclude that you're correct in your personal determination of bad faith, because you haven't explained that quote [0] which was evidently incomprehensible except to yourself.

Are you sure you want to talk about the topic? Clearly explaining what you meant there [0] would be a good start if so. Why not just say what you mean, and we can all have a civil discussion? Everybody wins then, right? Not that I'm forcing you to discuss anything civilly if you're not into it.

Except that argument admits a means to evaluate it. You take the thing repeated ad nauseam and subject it to an evidentiary requirement. Are people actually being held without habeas corpus? Are people actually being executed based on their ethnicity? If anything in this nature is happening, has the rate of it significantly increased recently or has it been going on for decades?

The last question is pretty important if your argument is "Trump is a fascist and all we have to do is get him out", because then that argument is erroneous and you have to actually change the status quo instead of returning to it.
Proposal: GUI-first, text-based mechanical CAD inspired by software engineering
by thinkmachyx | 2025-07-05 18:37:00+00:00
Most mechanical CAD tools (SolidWorks, Fusion, FreeCAD) still lock all modeling into opaque binary files. That makes it hard to track changes, collaborate with Git, or automate builds.

I’ve written a proposal for an alternative paradigm:

- GUI-first, like KiCad - visual modeling is the default

- Text-based source files (YAML/JSON) — readable, diffable, Git-friendly

- Separation of source and result - .step, .stl and previews are built artifacts

- Parametric logic is explicit - slot width = tab width + clearance

Works with Git, CI, or scripting — no more PDM lock-in The proposal is called SplitCAD, and it's just a concept for now — not a working tool. But I’d love to hear from anyone frustrated by the limitations of current mechanical CAD.

The real moat of low status is something completely different.

It consists on punishing people with low status when they objectively succeed and doing so brutally if they excel.

This entire post sounds like the complaints of someone with extreme privilege that lived a completely sheltered life.

In fact, the title of this blog, "Useful fictions", plays exactly into that.
