The only convincing explanation of the benefits of stablecoins I have seen is that it is a backdoor for implementing narrow banking, which libertarians love and economists and central bankers hate (as it would cut off credit to the economy).

A narrow bank is a bank that takes deposits but doesn't make loans, basically parks the cash at the central bank or into risk free instruments. So it provides you with payment facilities, very low interest rates, without the credit risk that comes with a large bank that has exposures to all sorts of risky businesses.

Everything else is either temporary benefits of arbitraging slow moving regulations (but KYC, consumer rights, money laundring regulations, etc are quickly catching up), or as you suggest, some non sense about a zero trust system (crypto / public ledger) that fundamentally relies on trusting a custodian (so you might as well use an oracle database and spend in licensing what you save in energy cost!).

There are easily 10x more fresh water plants in the US than nukes in both countries arsenals combined.

Not to mention fresh water wells on private property, which are 100x or more.

I’m not saying Nukes won’t cause damage - just that there is zero chance they can cause the pervasive, complete destruction of ‘everything’ that movies portray. There just aren’t enough of them. And no one knows enough or is competent enough to identify everything of value.

Don’t live in a high value target area though, or next to a major military base.

You obviously have absolutely no idea what you are talking about when it comes to music.

Coltrane is so respected because he use to fall asleep with his saxophone in his mouth because that is the level he would practice.

He represents the ultimate dedication to mastering an instrument.

You should really try making some friends with black people that like jazz so you can understand what a clueless thought this is.

I eat lots of salmon and sardines, I go outside, and I don't worry about my intake of vitamin D.

Bulk sardines from Costco, Sam's Club, etc., are a great move in general: low on the food chain; tons of protein, vitamins, and healthful oils; inexpensive; delicious; minimally processed; and shelf-stable.

I agree.

Better committing $20B now (by one player) than only talking about it and continuing to rely on others.

And while the point about OSes is also well made, there is no reason to believe that this will not also happen, albeit at a slower pace and via community mechanism rather than SAP funding.

I've seen many projects that go in that direction that have been launched. In a way, one has to 'thank' Trump for incentivising fixing something that should already be done right from the start, and which otherwise would have left undone for longer.

Reading the article made me think about other examples of Commons-Based Peer Production (CBPP). The Wikipedia page on CBBP lists examples like Linux and OpenStreetMap.

Although CBPP shares a lot with general User-generated content (UGC) and the open source model, maybe mechanisms that make it work is a little different.

The article points out system-side elements like "Talk page" and human-side elements like policies and guidelines.

I wonder if there are any studies on this subject.

The biggest problem with PID control is that the integral term performs double duty as both a signal that accumulates small errors to minimize the steady state error, but also as a signal that shows deviation from the target due to unmodeled constraints.

It should be pretty obvious that you cannot overcome constraints by moving even harder in the direction of the constraint, which is what the integral term does.
Show HN: I Built Open Source Claude Code Alternative, but Better at API Testing
by hervekom | 2025-09-05 11:06:47+00:00
Hi! My name is Herve Kom, a computer science student that is interested in learning new things everyday!

As one of my graduation project, I have developed a Claude Code -like Coding CLI, but with enhancement for API Testing:

- Auto-generate & run tests (unit, e2e, Playwright, CI/CD, etc.)

- Say bye-bye to hallucinations with built-in MCP Server to let LLM directly read from API Docs

- Adding Agent.md support for better context persistence across your whole codebase

- Automatic bug & security scans (logic is kind of basic but works great!)

- Vibes, I want it to feel less "enterprise" but more fun!

You can check the demo video in my github repo. Try it out!

Here's the best video I have seen about transformers [1]. It is made by Welch Labs. It talks about DeepSeek and what their main innovation was, but it covers transformers in general too, and I couldn't find any other better description of transformers.

I understand you made the app because of your own needs as a someone in a co parenting situation, but you’d have a lot more luck by removing that from your pitch. I see on your website you’ve mentioned friends or roommates which is a much bigger market.

Yeah, worlds slowest and most in-efficient write-only database. And as soon as you need to interact with goods or services in the real world, then you still need trust anyway.

All these people harping on about: "Bro I just need to move my money without trusting anyone!, I just need a trust-less way to send currency bro!"

Trust is a good thing! Banks and financial middlemen aren't the devil. Look at how many TPS the visa network can do thanks to trust.

If it weren't for some minimum of social/institutional trust the whole of society would collapse anyway and your digital coins would finally converge to their true value (zero - or actually negative once you add in the externalities).

> as much type safety as python

There's no type unsafety from unchecked exceptions, because uncaught exceptions are not unsound. Even Haskell has them (error and undefined), because from a theoretical standpoint they're equivalent to reaching an infinite loop. (Now, recovering from an exception isn't unsound either, but it might mess with your usual mutable invariants.)

In more practical terms, concerning overall correctness, OCaml has been adding option-returning variants of those functions, so most exceptions raised from the stdlib nowadays are much more likely to be intended by the author.

> Europe relies way too much on US companies

What annoys me to no end is the temporal amnesia there is to this. Sure, yeah, true, cloud providers are practically an American cartel at this point in time. But cloud itself is a fairly novel thing in most corporate histories: we used to run most things on premise with people on payroll, and that was a single digit years ago. Moving out of the cloud is as valid an option, if not a better one, than trying to come up with a competing cartel.

>length of this guide is a reminder that it is still really hard to host your own mail

I disagree.

Hosting your own email is really easy. I've been doing that for decades and I rarely need maintenance other than regular updates and backups. Minutes a month at most, usually.

That said, setting up your own email hosting is rather involved, although you can limit that to a certain extent with platforms like mail-in-a-box[0] and a raft of others.

If you're comfortable with basic Unix/Linux CLI tools and shells and you are able to follow explicit instructions, it's not too difficult to set up -- but it will take some time as there are a lot of moving parts

You may think I'm splitting hairs. But I don't mean to do so. Once it's set up properly, hosting your own email is incredibly easy.

That's an interesting point, but one way I can think is that as AI generated homework is completed by AI, "all natural" student performance may seem abysmal in comparison. The students who use AI to do the "grunt work" like paper writing will have more time to do things like attend office hours, befriend professors, network, get internships, or whatever other useful things they can do with their time.

It makes me think of the rampant cheating culture in the PRC. Cheating generally isn't considered immoral, or, it may be, but the attitude is basically "well everyone cheats, so you better do it too or you'll be left behind." University becomes a performance, and all thoughts are turned towards how to present the best in that performance. If you ask someone that buys into this system about the value of, idk, writing a paper so as to learn the material, they'll be very confused. What's the point of learning the material? The only thing that matters is getting the best grade possible. Then you can get the highest paying job possible. That's all that matters.

This is of course not universal, the PRC is a country with a gajillion people in it, but this is what I experienced at university there and when I returned to the USA and was the defacto "PRC student tutor" at my university because of my Mandarin and time spent there. I must have been offered money to write essays for people over fifty times.

So, I can imagine this happening with AI. What does it matter if you learn the material? You use AI to get a good score and then you use AI to do your job anyway so who cares. AI written emails summarized by AI, replies written by AIs, reports generated by AI, sent, summarized by another AI...

I forgot that this GC is non-moving (I'm not used to that assumption, and it was a bit of a quick comment).

I do find the statement dubious still, do you mind clearing it up for me?

Given a page { void* addr; size_t size; size_t alignment; BitMap used; } where used's size in bits is page.size / page.alignment, surely we only need to visit the used bitmap for marking a memory slot as free?

"Best movie" lists tend to have films with both critical acclaim and audience appeal.

It got critical praise but was a flop at the theater. The home video market redeemed it (haha) with audiences. From the article:

"Despite its disappointing box-office returns, in what was then considered a risky move, Warner Home Video shipped 320,000 rental video copies throughout the United States in 1995. It went on to become the top rented film of that year. Positive recommendations, repeat customer viewings, and being well received by both male and female audiences were considered key to the film's rental success."

All 3 movies (It's a Wonderful Life, Groundhog Day, and The Shawshank Redemption) had critical praise upon their initial release. Groundhog Day was even a solid hit. But no one could've predicted what they became later.

IMHO Garbage collection is and always was an evolutionary dead end. No matter how nice you make it, it feels wrong to make a mess and have some else clean it up inefficiently at some point later.

And because of that it always involves some sort of hidden runtime cost which might bite you eventually and makes it unusable for many tasks.

I'd rather have my resource management verified at compile time and with no runtime overhead. That this is possible is proven by multiple languages now.

That being said, I can imagine some C programs for which using Fil-C is an acceptable trade-off because they just won't be rewritten in language that is safer anytime soon.
by writebetterc | 2025-09-05 11:16:58+00:00
I don't think it counts as visiting, as you never look at the dirtied bitmap during GC, only during allocation. That means, you don't actually know if a dirty bit represents a different object or not (if a 16-byte size class is allowed to have 32-byte objs in it, for example). To know that you'd either have to have strict size classes, or you'd have to have object headers for specifying the start of an object.

I agree that it's easy to add in a visitation pass, where you take the bitmap of live objects after marking and diff it with the currently existing one in order to signal that you might have a leak.

So basically, I think we're like 99% in agreement.

As a european I dont believe in European anything. I worked for European scale-ups and they are all bunch of nationalists that primarily succeed in their primary country and then fail to expand in any other country because they meet the local alternative.

The best market to expand besides your own Euro-country is the US but tthen when you enter that market you are too small of a fish to do anything.

There is no such thing as european companies. It's german companies, french companies all mainly focused on their main markets.

Your comment does not make much sense even if it is true.

Factor (Forth-like language) implements even its own ":" (defines a word, i.e. a function) using the language itself, it is not builtin, same with "if", and so forth. Thus, "MEMO:" or locals[1] ("::") being implemented as a library does not mean it is a bad thing, on the contrary, in the case of Factor, it makes it quite powerful. The object system is entirely implemented in Factor, too. "Large chunks of functionality are not part of the core language, they are in just as library".[2]

And to compare OCaml's type system to Python's is straight out absurd.

[1] Locals are entirely implemented in Factor, too, which is only about ~500 lines of code. It is not part of the core language, and on top of that, there is no performance penalty whatsoever!

I gave you the most dramatic example. So far no undercollateralized, algorithmically backed $1 stablecoin has sustained a reliable peg at scale over multiple years.

Zero. Nada. There was always somebody somewhere exploiting it.

TerraUSD USN USDN Basic Cash

All failures so far, every time a death spiral.

FRAX started as algorithmic and had to move to over collateralization

Same with DAI

You really can’t call them like that once they become backed by USDC

Rasterizer excels at animation and complex scenes, e.g. 2D CAD documents. The original inspiration was Flash, as I love innovative design tools. Flash 1.0 could easily be used by designers, but ultimately lost its way became a coder's toy after the Adobe acquisition and ActionScript 2.0.

An implicit fee by not paying you any interest for money held in Venmo.

Also notice there's no option to automatically transfer received money into your real checking account. They are banking on you forgetting your money is there and they are earning the interest but not passing it to you.

For this reason I prefer receiving money via Zelle but pay with Venmo.

Is this like Uber and AirBnB all over? They don't want to be a bank just like Uber doesn't want to be Taxi (means following regulations about insurance, accessibility etc) and AirBnB doesn't want to be a hotel nor a landlord?

In some countries, regulators simply point to these companies and say "Ok, so you're driving people around for money thus you are a taxi? How would we not regulate you as a taxi?".

And this should apply for a bank or financial institution that tries to avoid banking regulations through technical means, no?

Just skimmed through the docs - this is super interesting. Love the idea of a minimal GC with no runtime dependencies. Anyone here tested it with something more intense than toy benchmarks? Curious how it handles edge cases under memory pressure or concurrency. Also, would be great to hear how it compares to Boehm or Rust’s drop model in real-world workloads.

Ask gay people in Iran, Uyghurs living in China, and investigative journalists in Washington, if encrypting internet traffic is a good thing or not.

Maybe a more relatable scenario for you - it was only a few years ago that you could turn cable modems into promiscuous mode to see ALL PLAIN TEXT TRAFFIC of the people living in your street!

So, if you you still think encryption isn't needed for the average person - what's your gmail username and password?

So what if it’s Dave Plummer? The name doesn’t make the post any stronger. The problem with his screenshot is the lack of context — network usage by itself doesn’t prove anything malicious or even unusual. Devices like Echo Shows pull constant updates, stream visuals, cache media, and maintain active connections. That can easily add up to gigabytes, even if the owner never directly ‘uses’ them. Acting shocked about it without explaining the why just turns into clickbait.

I always wondered how secure AS/400 actually is. The original implementation might have checked tag bits in hardware (I don't know), but the current (PowerPC) implementation relies on the compiler generating a "check tag bits" every time a pointer is dereferenced [1]. So it seems that any arbitrary code execution vulnerability would be absolutely devastating. And the "SLIC" is not a small microkernel -- it also contains the compilers, the database and other system components. It'd be hard to believe there would no exploitable bugs in there.

We have an impossibly pervasive network of sensor blisters littered throughout our lives, to the point where I don't feel comfortable discussing certain sensitive topics in most other people's homes, but every step of the way most normal people have given the same refrain: "oh, the tech companies probably already have all my data anyway"

Now that those tech companies are working closely with an American regime that seems increasingly willing to disregard the rule of law and public perception to round up people they deem undesirable in large numbers and put them in concentration camps, and we have natural language processing tech that can pretty effectively filter through large amounts of text for some semantic analysis, I hear some of the more attentive people coming to the barest hint of a realization that this situation is unacceptably dire

I keep the car at 20-80% when at home and driving around the city, I charge once a week. Before a trip, I let it charge to 100%, then charge to 80% on the trip (otherwise you waste time on the slow parts of the charge cycle).

It's really not a hassle at all. What's a hassle right now is finding a charger, as there aren't enough fast ones along the trip, but I've had the car for a year and have never needed to do a trip that long yet.

I see some value in that, but in my experience it's actually the queries that inform much of what the table shema and indexes should look like. Especially when joins and/or ordering are involved, it's the details about what the application wants to extract from the DB that are important, and I'd rather have those details at the code's call site not at the schema definition, because if/when they change or are removed it will be clearer from the context.
