.borrow() already has a hidden unwrap. There's try-borrow(), but the assumption for .borrow() is that it will always succeed.

What I'd like to do is move as much of the checking as possible to the drop() of the owning object, and possibly to compile time. If .borrow() calls are very local, it's not too hard to determine that the lifetimes of the borrowed objects don't overlap.

Upgrade is easy to check cheaply at run time for Rc-type cells. Upgrade only fails if the owning object has been dropped. At drop, if weak_count == 0, no dangling weak references outlive the object. If there are more strong references, drop would not be called. With that check, .upgrade() will never fail.

After all, when a programmer codes a potentially fatal .borrow(), they presumably have some reason to be confident the panic won't trigger.

I was pretty skeptical too, but it looks legit to me. I've been doing Zig off and on for several years, and have read through the things I feel like I have a good understanding of (though I'm not working on the compiler, contributing to the language, etc.) and they are explained correctly in a logical/thoughtful way. I also work with LLMs a ton at work, and you'd have to spoon-feed the model to get outputs this cohesive.

Yes, but when your starter project takes off and you start to get serious traffic, there’s no good path to migrate off. It’s all very manual, and involves a fair amount of downtime unless you have the requisite knowledge to set up logical replication; even then, unless you know how to chain replication, you’re going to thrash your buffers, and cause slow queries for existing traffic.

I actually have (and a few of his other articles besides).

If we were to involuntarily take someone into society's care, the process must be benign with a good outcome. As things currently are, the exact opposite (or a system so thoroughly financialized as to be almost the same) is present. The capacity to reverse this seems non-existant.

Most calls right now to reinstitute involuntary commitment are the same thought process that results in the societal rot present in how we deal with poverty, homelessness, and addiction; they just want them even further removed from themselves so they don't have to witness it.

> Knowing that there are two constructors that exist for normal, non-native, Python classes, and that the basic constructoe Class.__new__, and that the constructor Class() itself calls Class.__new__() and then, if Class.__new__() returns an instance i of Class, also calls Class.__init__(i) before returning i, is pretty basic Python knowledge.

I disagree that this is basic knowledge. In python a callable is an object whose type has a __call__() method. So when we see Class() its just a syntax proxy for Metaclass.__call__(Class). That's the true (first of three?) constructor, the one then calling instance = Class.__new__(cls), and soon after Class.__init__(instance), to finally return instance.

That's not basic knowledge.

Right. The whole problem with all this is ergonomics, from the point of view of programmers who don't want to obsess over ownership and type theory. We sort of know how to make this work. It works fine with enough Rc/Weak/etc. But it's a huge pain.

I appreciate people arguing over this. It helps. We've seen proposals from people who are too much into the type theory and not enough into ease of use. I used to do proof of correctness work, where the problem is that proof of correctness people are too into the formalism and not enough into killing bugs.

We should have laws and regulations for things that are important and (relatively) easy to define and enforce. But laws and regulations aren't enough, because people find loopholes, and trying to patch these loopholes with more laws and regulations doesn't work.

Examples of "obvious" laws and regulations: physical violence should be policed, companies should have to pay salaries and have basic restrictions on work hours, safety, sanitation, etc. Examples of things that can't really be regulated: "gambling" and "harmful social media". When does a game become "gambling"? When does a site become "social media" and "harmful"? Various countries have legal definitions for these, but they're very long, so companies find loopholes (e.g. sports betting, loot-boxes); or they straight-up break the laws, but the government doesn't bother to enforce them, because it's too difficult and the general population doesn't notice or care enough. Complex and ineffective laws and regulations also tend to have unintended consequences, like Balatro being considered "gambling" in Australia, and the UK's "Online Safety Act" affecting small forums.

Part of the reason is that the people writing and enforcing laws and regulations themselves are corrupt. But this goes back to the source: you can't police those people with more laws, because their enforcers are also corrupt, and so on. A society is controlled and its morality is defined by its people, so to some extent, a society must teach its people to be moral and give them the leeway to still behave immoral.

Idk, I get weird refusals sometimes when I'm trying to mock something up quick. "I don't need all these system variables and config files, just let me hardcode my password for now, I'm still in the testing phase" "Sorry, I cannot help you to write insecure code". Doesn't happen all the time, but I run into dumb stuff like this quite a bit. GPT is particularly stupid about it. Claude less so.

Several issues:

1. Reducing dependencies is a wrong success metric. You just end up doing more work yourself, except you can't be an expert in everything, so your code is often strictly worse.

2. Regenerating the same solutions with a probabilistic machine will produce bugs a certain percentage of the time. Dependencies are always the same code (when versioned).

3. Cognitive overhead for human review is higher with LLM-generated libs, for no additional benefit.

I think there's a space for something that wraps an llm (especially multimodal) to do something that's halfway to agentic. Yes you could do it yourself but it's not worth it to you to figure out prompts etc, especially when someone has already optimized it. Plus, it could go from 100 clicks and 10 minutes in front of chatgpt to zero clicks, automated ingest, and get an email when the results is baked.

A good example I saw recently was stripping ads from podcasts.
by koliber | 2025-11-16 20:31:17+00:00
I guess you’re right re chatbot for summaries. I was thinking about the use case and not the whole integrated product experience.

For example, for code gen I use agents like Claude Code, one-shot interfaces like Codex tasks, and chatbots like the generic ChatGPT. It depends on the task at hand, how much time I have, whether I am on the phone or on a laptop, and my mood. It’s all code gen though.

An LLM might be able to replace the majority of the code Sindre Sorhus has put out there, but it's probably a stretch to think that it could replace someone like John Carmack.

Trivial NPM libraries were never needed, but LLMs really are the nail in the coffin for them even when it comes to the most incompetent programmers because now they can literally just ask an LLM to spit out the exact same thing.

> Teachers can’t be bothered to close the test when class ends!

What about students who need extra time, which can be part of an IEP, and other issues, I don't think that part is lazy. Also a decent amount of the usage of Canvas or similar LMS's is subject to school or district wide rules.

Edit: I taught highschool CS during the pandemic to try to help out with issues in my district.

> It also gives him a way of dealing with the increasingly mandatory state-controlled national messaging app, Max. The service has no end-to-end encryption but is needed to access any state service

That's a lie. No state service requires Max for access.

>Now Russia is increasingly shifting to “white lists” — strictly limited lists of government-approved sites that Russians may access, with other sites blocked.

First the article cites some stupid people complaining about mobile internet shutdowns needed to complicate Ukrainian drone attacks. Next the article presents the government's efforts to mitigate the effect of the mobile internet shutdowns on the civilian live by whitelisting services that must be always available as something nefarious.

Is there any scenario in a sane world where a transaction ceases to be in scope just because it went into an error state? I'd have expect the client to send an explicit ROLLBACK when they realize a transaction is in an error state, not for the server to end it and just notify the client. This is how psql appears to the end user.

postgres=# begin; BEGIN postgres=*# bork; ERROR: syntax error at or near "bork" LINE 1: bork; ^ postgres=!# select 1; ERROR: current transaction is aborted, commands ignored until end of transaction block postgres=!# rollback; ROLLBACK postgres=# select 1; ?column? ---------- 1 (1 row) postgres=#

> Reducing dependencies is a wrong success metric. You just end up doing more work yourself

Except it's just not true in many cases because of social systems we've built. If I want to ship software to Debian I have to make sure that every single of my 3rdparty dependencies is registered and packaged as a proper debian package - a lot of time it will take much less work to rewrite some code than to get 25 100-lines-of-code micro-libraries accepted into debian.

Their are many good reasons to always have a primary key, even if it is just an automatic serial number, but the one that hit me personally is that it is surprisingly difficult to deduplicate a relational database.

When I was first learning SQL I was pretty firmly in the "use natural keys" department. And when the natural key was every single column I would go "whats the point?" shrug and have no primary key. Until I started getting duplicated rows

insert into customer_email (name, address) values ('bob', 'bob@bobco.com'); insert into customer_email (name, address) values ('bob', 'bob@bobco.com');

Duplicate rows a. tend to mess up your query results and b. are surprisingly difficult to remove. If I remember correctly after spending far too long trying to find a pure sql solution I ended up writing a program that would find the duplicates, delete them(all of them as there is no way to delete all but one) then re insert them. and adding that missing primary key.

I still like natural keys more than I probably should. (you still need a key to prevent functional duplicates, even when using a surrogate key, why not cut out the middle man?) But am no longer so militant about it(mainly because it makes having dependent tables a pain)

> It’s posed to get significantly stronger

It's really not. Every project of any significance is now fending off AI submissions from people who have not the slightest fucking clue about what is involved in working on long-running, difficult projects or how offensive it is to just slather some slop on a bug report and demand it is given scrutiny.

Even at the 10,000 feet view it has wasted people's time because they have to sit down and have a policy discussion about whether to accept AI submissions, which involves people reheating a lot of anecdotal claims about productivity.

Having learned a bit about how to write compilers I know enough to know that I can guarantee you that an AI cannot help you solve the difficult problems that compiler-building tools and existing libraries cannot solve.

It's the same as it is with any topic: the tools exist and they could be improved, but instead we have people shoehorning AI bollocks into everything.

Completely unsupported assertions are the least interesting kinds of comment anyone can post.

Besides, this particular comment would need to explain why it’s likely that its unsupported opinion is correct, rather than all the counterexamples that exist in the actual highly competitive industry that’s heavily using this system.

There’s a fundamental conflict there that doesn’t work in favor of your inchoate opinion. The most likely conclusion is that there are factors at work here that you don’t understand.

> So you can never give a support chatbot real support powers like “refund this customer”, because the moment you do, thousands of people will immediately find the right way to jailbreak your chatbot into giving them money.

And that's the elephant in the room. AI "agents" can't do much until someone solves that problem. Most AI "agents" work for and favor the business operating the agent, but impose the costs of their errors on the customer. Errors are an externality, like pollution. This is no good.

Zero upside? LOL, no.

I'm looking for convincing decoy ALPR cameras because I don't think my HOA will go for a real setup, and I've got concerns over the product's security. I want the appearance of surveillance if I can't get the real thing. Being on a Flock/ALPR tracking app/site would be a huge win.

There is no benefit to signaling one's virtue in this scenario. It's like having a sign in your yard that says "Proudly Gun-Free Household".

> The AI water issue is fake

What a relief!

So, I guess we can expect advocates to avoid any hilariously weak strawmen then, right?

So, the regulation making evaporative cooling illegal in datacenters is being voted into law as we speak, right?

Since its such a fake issue, then regulation capping datacenter water use is being voted into law as we speak, right? Should be straightforward enough since we know exactly how much water that is needed and being used, right?

I really don't get the point the article is making. I think the whole point about curve fitting is really a distraction, they could have simply stated that the FFT has periodic boundary conditions, so if you take the FFT of something that only extends a finite time of your sampling window, you will see your delta functions in the frequency domain spaced by the inverse of the length of your sampling window, i.e. the FFT "sees" your finite window as a pulse train. That's well known and a fundamental aspect of Fourier transforms.

But then the statements about the discontinuous "vibrations". E.g. in the case of the 1 Hz cycle over half the window the author states that:

> Yet the FFT of this data is also very complex. Again, there are many harmonics with energy. They indicate that the signal contains vibrations at 0.5Hz, 1.0Hz, 1.5Hz, etc. But the time signal clearly shows that the 'vibration' was only at 1Hz, and only for the first second.

The implication that there is a vibration only at 1Hz is plain wrong. To have a vibration abruptly stop, you need many frequencies (in general the shorter a feature in the time domain the more frequency components you need in the frequency domain). If we compare for example a sine wave with a square wave at the same frequency, the square wave will have many more frequency components in the Fourier domain (it's a sinc envelope of delta functions spaced at the frequency of the wave in fact). That's essentially what is done in the example the sine wave is multiplied by a square wave with half the frequency (similar things apply to the other examples). Saying only the fundamental frequency matters is just wrong.

This is also not just a "feature of the fitting to sines", it's fundamental and has real world implications. The reason why we e.g. see ringing on an oscilloscope trace of a square wave input is because the underlying analog system has a finite bandwidth, so we "cut-off"/attenuate higher frequency components, so the square wave does not have enough of those higher frequencies (which are irrelevant according to the author) to represent the full square wave.

"nobody uses in the real world yet" is uncharitable, as Zig is used in many real-world projects (Bun and Tigerbeetle are written in Zig, for example). But there's value being at the forefront of technologies that you think are going to explode soon, so that's how people find time and energy, I guess.

> the era of small, low-value libraries like blob-util is over.

Thankfully (not against blob-util specifically because I've never intentionally used it), I wouldn't completely blame llms either since languages like Go never had this dependency hell.

npm is a security nightmare not just because of npm the package manager, because the culture of the language rewards behavior such as "left-pad".

Instead of writing endless utilities for other project to re-use, write actual working things instead - that's where the value/fun is.

Your company is sheltering some of the worst individuals who work to destroy privacy and security.

From the link that you posted, the first thing it asks for is your full name. This is the same when attempting to signup for the VPN service. If paying with crypto, the process tries to steal even more info from you such as zip code and country. No other normal privacy or VPN services ask for a full name or zip code.

The "freedom policy" on the site talks about how the company won't spy on anyone or do anything to compromise privacy, then goes on to talk about "think of the children!"

Minors might subscribe to privacy services. Vp.net would harm minors more than a child predator due to the false sense of security and privacy.

The business lies to everyone saying it is secure because of SGX, which has new vulnerabilities pop up weekly.

> There isn't anyone pointing a gun to someone's head forcing them to using 100% of all C++ features in every single project.

Tell me how to use C++, without using RAII. You can't. Not being able to automatically allocate without also invoking the constructor is what I dislike the most in C++. Other things are, that you can never be sure, what a function call really does, because dynamic dispatch or output parameters aren't required to be explicit.

> I hold this point of view since 1993, having used C instead of C++ was only when obliged to deliver my work in C, due to delivery requirements where my opinion wasn't worth anything to the decision makers.

Wireguard is much better. Not only is it easier to set up/maintain, it even works on Android and iOS. I used to use client authentication for my private git server, but getting client certs installed on every client browser or app was a pain in the ass, and not even possible for some mobile browsers.

Today, my entire network of self hosted stuff exists in a personal wireguard VPN. My firewall blocks everything except the wireguard port (even SSH).

1) But with quite a hefty penalty on writes... I'd think you would be better off without a primary key and just using a BRIN index for that use case?

2) Even if you did really want that B-tree, you can still have it and not have to have to awkwardly make it unique if you don't make it a "primary" key.
by lanstin | 2025-11-16 20:43:29+00:00
Yeah if I find some (small) unmaintained code I need, I will just copy it (then add in my metrics and logging standards :)

It shouldn't be a radical idea, it is how science overall works.

Also, as per the educational side, I find in modern software ecosystem, I don't want to learn everything. Excellent new things or dominantly popular new things, sure, but there are a lot of branching paths of what to learn next, and having Claude code whip up a good enough solution is fine and lets me focus on less, more deeply.

>Look I’m pretty far to the left... The luxury of accepting the dominant narrative is the luxury of the privileged.

I think the true leftist response to this is that you're already doing this by consulting the AI. What makes the AI any less biased than the controls put on the AI? If anything, you're more accepting of the "dominant narrative" by pretending that any of these AIs are unbiased in the first place.

“AI was created through a narrow lens that inherently perpetuates existing biases around gender, and undermines the importance of a diverse and inclusive workplace.”

“Another way to address intentional or unintentional bias within any tech roles is to increase efforts to recruit more diversity across a tech workforce. This means having a diverse recruitment drive in tech and software development roles, i.e. including women, people of colour, those from different socioeconomic levels, anyone across the LGBTQ+ spectrum, people with disabilities, diverse cultures, religions, and geographic regions.”

LLMs can be used to quickly mulch data into a digestible format that at least used to take effort. Friction is a natural deterrent for bad behavior. Beyond that, however, is the fact that your user interactions with most applications used to be quite coarse. A "customer story" was just that: a story we crafted from the data we have available to us about our customers. We have to build it from heuristics like bounce rate, scroll distance, and other thorough, idiosyncratic and diligent abandonment metrics.

Now why bother? Your customer will ask their silver ball (LLMs) anything and everything, and you can directly do bulk analysis on (in theory) the entire interaction, including all of your customer's emotions available via text.

Lastly, your customers are now eager about this tool, so they're excited to integrate/connect everything to it. In a rush to satisfy customers, many companies have lazily built LLM integrations that could even undermine their business model. This pushes yet more data into the LLM. This isn't just telemetry like file names, this is full read access to all of your files. How is that not connected to privacy?

Even if what you say is true, people make bets on new tech all the time. You show up early so you can capture mindshare. If Zig becomes mainstream then this could be the standard book that everyone recommends. Not just that, it’s more likely the language succeeds if it has good learning materials - that’s an outcome the author would love.
