Stop pushing POCs into PROD.

There's nothing wrong with making your POC/MVP with all of the cool logic that shows what the app will do. That's usually done to gain funding of some sort, but before releasing. Part of the releasing stage should be a revamped/weaponized version of the POC, and not the damn POC itself. The weaponized version should have security stuff added.

That's much better than telling people stop making apps.

The highway speed scatterpot in the US has a floor at the "speed limit" and the median speed is usually 10mph to 15mph higher than that. In this scenario, driving the "speed limit" means nearly all other users will overtake you at a significant differential, and some in a disorderly manner. Consistently doing so in heavy traffic provokes backups and the usual consequences to other drivers.

> Critics of Python don't get "silenced in their bubble" generally, just ignored.

I disagree. The public bans are just the tip of the iceberg. Here is a relatively undocumented one:

https://lwn.net/Articles/1003436/

It is typical for a variety of reasons. Someone complains about breakage and is banned. Later, when the right people complain about the same issue, the breakage is reverted.

The same pattern happens over and over. The SC and the PSF are irresponsible, incompetent and malicious.

Most of the top 16 signers of the open letter are well-known names in Organic Maps, and the Updates to the letter try to fairly characterize the (lack of) response from OM. It's hard to link directly to raw evidence for the general public to review, since the most concerning topics (what will owners do in the future, what have they done with donation money) were in chat rooms that don't have public links and are exactly what the letter is asking for OM "owners" to provide. https://openletter.earth/open-letter-to-organic-maps-shareho...

Here's the CoMaps governance repo for deciding on decisionmaking: https://codeberg.org/comaps/Governance/ and the leadership here https://codeberg.org/org/comaps/members vs top contributors to OM since the Maps.me fork: https://github.com/organicmaps/organicmaps/graphs/contributo...

We've got some FAQs up about legitimacy and plans but the website was literally coming together over the weekend, so there's more work to be done for sure. https://www.comaps.app/support/ -- one thing we're also trying to do is focus on the future rather than rehash issues that haven't seen resolution in chat channels in over a month and don't seem to be getting resolved any time soon. The community and users deserve an actively-developed app, and the CoMaps founders don't want to continue contributing to a for-profit app, so in absence of a timely satisfactory resolution all our energy is going into the fork!

Marking the road at its engineered speed is ineffective. People overwhelmingly do not use speed limits to decide how fast they drive. They look at how wide and straight the road is and how many things they see. The problem is we built a lot of streets that are engineered to be 50mph roads in residential neighborhoods. People then ignore the 25mph sign and drive 50mph and hit little children playing outside their home. Rebuilding and rerouting the road is impractical, so how do we fix the problem? Empirical evidence shows that by adding "distracting things" people drive slower, and this results in few fatalities.

You are thinking of them as "distractions" but counter intuitively it might better to think of them "focus holders". Imagine your job is to sit in an empty room with a single button and at random times, a light turns on and you need to push the button within half a second. If this happens every several seconds or so, this is pretty easy, but if it only happens after an hour or so your mind will be wandering and your reaction time will be shit. Now imagine instead you are given a platforming video game like Mario or Hollow Knight, and every time a certain character appears on screen need to push the Y button. This sounds like something that is easy to do for hours, even if the specific character appears infrequently, it would even be enjoyable. Adding those elements like trees, turns and bumps are the same idea, it ensures the drivers focus is always on the road where it needs to be.

Also some people just don't care and race down wide straight roads as fast as they can. The only way to slow these people down is to make it impossible to go extremely fast. I can think of this play ground near my house which is across the street from a school. In orders to stop people speeding down this straight street, the placed large rocks in the middle of the road, so you have to dive this zig zag pattern. I sure this can be somewhat frustrating for drivers but it's now impossible to navigate this road at more than ~20 mph which is what we want.

As for moving interactions I think the idea of not having pedestrian crossings at intersections is infeasible. Though it might work if you were building a new city from scratch. When you are walking in a city you are going to cross multiple blocks. Walking ten+ blocks to get somewhere is so normal it’s not something you even think about. Crossing in the middle of the block would at least double and could triple or quadruple the length of the of a walk and city dwellers would simply not do it and cross at intersections. They already universally ignore traffic lights, and aren't going to walk out of their way dozens of times a day.

I could imagine a city that was designed around walking and all the shops and homes were on car free streets, with streets behind the houses, like alleyways or underground. That I could see working, but the problems with implementation are obvious.

It’s not surprising. They have a strong cultural identity and their whole country is far nicer and cleaner than any country I’ve been to.

Most immigrants here (I live in SF) are to be completely honest, not from very strong cultural identities. I’m an immigrant too, and my own people aren’t that strong with their cultural identities. After all, we GTFO’d the moment we or our parents could. Whenever I’ve been back I hated the filth and pollution everywhere, and the lack of care considering the litter and trash everywhere. It’s gross and sad.

Japanese people are happy with their culture on a broader level. I’m sure they have their problems too. Everyone does.

When I visited Japan I was so blown away by how proper and organized people were. It inspired me to live a more organized life. I went all over in both cities and rural areas, never saw trash. People were kind even with the language barrier. Even their homeless (they only have like 20k total) were polite and organized.

This particular Ars article mentions a 2021 book by RFK Jr, where he comes out as a germ theory skeptic.

In a previous Ars article, https://arstechnica.com/health/2025/04/rfk-jr-s-anti-vaccine..., we find that the 2021 book is titled "The Real Anthony Fauci". The advocacy of miasma theory appears in the chapter "The White Man's Burden". A book attempting to discredit germ theory basis of COVID by attacking the supposed leader of the pro-vaccine forces. This reminds me of creationists trying to discredit evolutionary science by attacking Charles Darwin personally, and maybe scientifically, which isn't too hard based on about 150 years of work revising and falsifying the original theories.

In any case, RFK Jr is probably doing this as a way to discredit any "bacterial" arguments for the basis of diseases. If he and his grandchildren can do it, they are healthy people, and the cautions about bacteria are irrelevant.

it really depends on what part of the country and the type of road and even the time of day

if I were to go even the posted speed limit during my morning commute, I would be causing a hazard. it's 5-10 over just to be safely part of the flow

same road in the evening and doing the limit or even a bit under is safe

imho, the dangerous drivers are those who for whatever reason do not base their speed on the flow of traffic around them

Shopify would benefit a ton from "some" namespaces. In a way, packwerk[0] was an attempt at bringing some namespaces benefits.

But I don't personally think Shopify would benefit from this specific implementation of namespaces (a couple colleagues do). I'm personally not even sure Namespace is a proper term to describe that feature. It's more some sort of lightweight sandboxing to me.

Also:

> They have so many expert Ruby devs

If anything, the average Ruby expertise at Shopify is likely noticeably lower than in most Ruby/Rails shop.

Stop focusing on the additives. It would be nice and convenient and comfortable if we could just lose certain preservatives or swap out certain ingredients and magically be healthy without actually changing our diets, but that's not going to happen.

We need to stop eating so much junk food. The densely packed fat, salt, and sugar are always going to be bad for us. Find ways to encourage healthy eating, especially getting kids into the habit of it and making good food just as affordable per calorie as the junk, and you will massively help with the health problems.

For my family it really wan't a trade off. This jobs was the only one we could do to make end meet.

My family is the 'petite bourgeois'(owners that labor alongside their workers[0]) that Marx said were the only people that actually had a choice in the class war and were the breeding grounds for fascism.

We did management too, but labored with the employees all the same. Did we get paid more? Sometimes, but we had to go without pay a lot and pick up other jobs. Still, my sibling and I went to college debt free, none of the employees' kids did that [1].

This is true of so many rules of thumb. The fact that something doesn’t work in all cases does not mean that those cases that it identifies as problematic can be ignored.

Spend less than you make is another one - sure there are edge cases where that is not appropriate. But in most cases, it is, but most people arguing that it doesn’t apply to them are they very people to whom it should apply most strongly.

I wonder how much research has gone into neutron-deficient materials for shielding?

Depleted uranium is one example but that has terrible implications due to radioactive pollution that would result, disposal costs and risks, etc.

Surprised theres not more research into meta-materials and alloys that are neutron-resistant, neutron-slowing, or neutron-absorbing.

There were the famous napster cases, the kids and old ladies that got sued by the RIAA for using limewire to download some music.

There is also the fact that copyright holders will pressure your ISP into sending threatening letters and shutting off your Internet for piracy, even without you seeding. I haven't gotten the impression that you are in the clear for pirating as long as you don't distribute.
Show HN: Sourcetool – Build internal tools with plain Go, no frontend
by theaktky | 2025-05-12 18:13:06+00:00
Hey HN!

I built *Sourcetool* because I wanted Retool-speed without leaving the IDE.

What it is:

* Write backend functions Sourcetool streams a WebSocket UI to the browser.

* No drag-drop builder, so Copilot / Cursor can read & refactor your tool.

* Everything is plain code → PR reviews, CI, Git history just work.

* Self-hosted binary, no data leaves your infra.

30-second taste:

```go

func usersPage(ui sourcetool.UIBuilder) error {

name := ui.TextInput("Name") // Just call your existing backend logic here // Example: a function that queries users from your database users, err := listUsers(name) if err != nil { return err } ui.Table(users) return nil

}

```

Try it out: https://github.com/trysourcetool/sourcetool

I'd love to hear your thoughts and feedback. Happy to answer any questions in the comments!

I think it's deeper than that. There's an incentive on not going against your own military because doing so would attract the wrong kind of mentality and makes things worse when you need them. So unless there are real consequences against brushing it off (like burning down public buildings) that's usually what happens. But publicly people cannot be too explicit saying it because it plays on the image of the pristine rule of law that our politicians like so much to use on speeches to make sure we're above China and other developing countries on the moral grounds.

> But you can read the books right in the library and learn from them.

What does this have to do with LLM training? Does OpenAI have a data center in every library, and only process data from that library in that data center?

You're not allowed to maintain a personal copy of a book you borrowed from a library, even though you pay a library fee. Neither should OpenAI, especially since they didn't even pay that small fee.

Also with mobile apps, app store users are the most "valuable" thing -- much like Maps.Me, the "app" could be sold tomorrow and what really happens is the FOSS code is thrown away or sunsetted and the users wake up to an update where their map app is now a crypto scam, or whatever. The source code can be forked, but Organic Maps "owns" millions of app store users, and can "sell" that, in a way that violates users' trust. Us volunteer developers are very against that, but unable to stop it besides protesting.

I disagree. Most AI innovation today is around things like agents, integrations, and building out use cases. This is possible because transformers have made human-like AI possible for the first-time in the history of humanity. These use-cases will remain the same even if the underlying architecture changes. The number of people working on new architectures today is way more than were working on neural networks in 2017 when 'attention is all you need' came out. Nevertheless, actual ML model researchers are only a small portion of the total ML/AI community, and this is fine.

> "You" is often plural.

If we're being pedantic (which we absolutely are at this point), "you" is always plural, and plurality is sometimes used to denote formality or respect for a singular subject (analogous to vous in French, or Sie in Germanic languages). It just so happens that we exclusively use the formal/respectful version in English these days.

The only truly singular singular second person pronoun in English is thou, which was the familiar form (although now because it is so archaic people ironically interpret it as more formal).

I haven't seen anything particularly unusual/novel/interesting in Odin that would draw me to take a closer look. Same goes for Jai. That's not to say that these languages aren't well-designed, but I didn't find some interesting overarching design philosophy that would draw my curiosity. Of course, I could be missing something.

There are some very successful uninteresting languages (Python and C# come to mind), but they don't give you much to think or talk about other than, perhaps, a particular interesting feature here or there. Again, that's not to say they're badly designed or don't deserve their popularity.

I've blabbered on about this too much, but I decided to see if there's been any progress on multithreading libraries for GPU and found some for lisp:

https://repository.lboro.ac.uk/articles/conference_contribut... (has pdf download)

https://github.com/michelp/hillisp

Unfortunately neither of these seem to do any heavy lifting, they just transpile lisp statements into GPU kernels like WebMonkey does. But it's a start.

To get real work done in concurrency with SISD/MIMD to SIMD transpiling, we'd need a small team with a modest budget to work for perhaps 2 years on figuring out how to statically analyze unmodified lisp programs and break them down into independent fragments that can execute in parallel without side effects. Then use libraries like these to run those fragments as kernels and aggregate the results. Conceptually this would work like a spreadsheet, watching for changes in inputs and calculating the result across as many cores as possible unsupervised.

Once that runtime reached MVP, work could begin on transpiling common languages like C and Javascript to lisp. This is also an open problem, but straightforward to solve. The difficulty appears to be that transpiling imperative code to lisp has only been done as a hack with impure or monadic logic that defeats the whole purpose of using functional programming. It also tends to lose human readability by using too much glue code through bindings, rather than naming variables common to both runtimes like how we name registers in C++ that can be used within asm() blocks:

People always ask which camera or lens I use, hence I added it upfront. Leica's are expensive I agree. It was a dream of mine to use it though for almost two decades. I finally was in a position to get it three years ago.

To your question, the RAW's, unprocessed files are not like this from a Leica. You need to color grade (photographers say "post processing"). Color grading is used mostly for Video. In Photography, there are a lot of other things, it's mostly about light, not color. Highlights, Shadows, Contrast, Blacks/Whites etc.. Of course colors are also very important.

If you want good colors straight out of the camera, you could look into FujiFilm.

Oops! Nice find!

To limit his legal exposure as a researcher, I think it would have been enough to create a second account (or ask a friend to create a profile and get their consent to access it).

You don't have to actually scrape the data to prove that there's an enumeration issue. Say your id is 12345, and your friend signs up and gets id 12357 - that should be enough to prove that you can find the id and access the profile of any user.

As others have said, accessing that much PII of other users is not necessary for verifying and disclosing the vulnerability.

Biome is an integrated linter/formatter for JavaScript/TypeScript, CSS, HTML and GraphQL.

We are now in the process of implementing TypeScript-like inference (not full type checking!) that allows us to enable type-informed lint rules. This is similar to typescript-eslint except instead of using tsc we attempt to implement the inference ourselves.

This post describes our progress thus far, with a detailed overview of our type architecture.

Industrial parks centered around power plants might become a thing in the future, being looked at as essential infrastructure investment.

Heat transport could be seen as an entire sub-industry unto itself, adding efficiency and cost-savings for conglamorates that choose to partner with companies that invest in and build power plants.

You are typing this with software built on top of an incredibly vast technology stack which simply would not exist without federal R&D funding. May be worth remembering this fact. In the next few hours, you will almost certainly use non-digital technology essential to life which simply did not originate from commercial R&D (such as it is).

The beginning is nearly always federal R&D funding. Much of it won't work, sure, and that's fine. It's not wasted, because when it works, it creates such a massive everlasting surplus and opportunity machine that it overcomes all past failures by orders of magnitude. Such as, computers, and all they enabled over the last 100-ish years.

hmm. fair enough. I have heard the short trip stat bandied about a lot. Having spent time with people in the suburbs, even close in suburbs, the stat makes sense... if you exclude commute to work. When I visit my parents in stroadville, a trip to the store is 2 miles each way and should be easily bikeable, but bike infra is non existent so everyone drives.

Another demonstration of positive-sum:

> It does so by expanding pedestrian areas via curb extensions or bumpouts, narrowing crosswalks, and removing parking within 20-25 feet of an intersection. [...] This not only slows traffic, but permits turning cars fuller visibility of the crosswalk.

Classical zero-sum thinking would suggest that drivers loose value to pedestrians, with more pavement and less road. However, you don't even have to think about pedestrians to understand why everyone benefits from this: in some American cities (I'm looking at you, Seattle) you have to edge absurdly far into intersections to see perpendicular. Broadening sidewalks improves driver-driver visibility too.

In this operating environment, under the right circumstances, I think it's entirely possible. Reality is suspended somewhat (not hyperbole imho). You just have to get the old man's ear and be ready to go from funding to pardon signing fast. If laws currently don't matter, that's opportunity. Social engineering, as old as time. Bad people will do bad things with this time window, but maybe we can do some good.
