I'm not sure where to even begin with this, but a large part of why free school lunches exist is that there are many kids in abusive or simply desperately poor families who do not get fed properly, meaning that the school lunch may be the only decent meal they get.

> Not giving people free things is not a punishment.

This is absurd. Kids don't have money to purchase what they need, so parents have a duty to feed, clothe, house etc them. Intentionally not providing children what they need, like food, is abuse, period.

None of these "issues" are systems issues, they're memory safety issues. If you think systems programming is about memory saftey, then you're demonstrating the problem.

Eg., some drivers cannot be memory safe, because memory is arranged outside of the driver to be picked up "at the right time, in the right place" and so on.

Statically-provable memory saftey is, ironically, quite a bad property to have for a systems programming language, as it prevents actually controlling the devices of the machine. This is, of course, why rust has "unsafe" and why anything actually systems-level is going to have a fair amount of it.

The operation of machine devices isnt memory safe -- memory saftey is a static property of a program's source code, that prevents describing the full behaviour of devices correctly.

Originally because it produced sound by heterodyning two sine waves.

Modern ones (the Moog ones I saw 20 years ago) have tunable waveforms but still hark back to that original sound.

I like the sound. In the sonic tradition of the cello.

Meanwhile, in Texas (~2005), we weren't even allowed to leave the building to eat on the patio outside in high school.

Something I thought a lot about when I moved to Mexico and saw kids leaving school at lunch to wander out and eat lunch together in the surrounding part of the city.

Too much dangerous liability to allow going outside during lunch hours in a wealthy part of Texas, but not in Guadalajara, Mexico and nor of the world. Sigh.

> Blu ray is 25GB per side, so max 50GB for 2 layers

Are pressed Blu-Rays limited compared to writeable ones?

I have 100GB BDXL blanks (single-sided) I use as one of the archives for my family photos/videos.

Couldn't a film BluRay also be 100GB on a single side?

Don't code, validate your ideas first (to first 1000 paying customers if monetization motivates) and 99% is not even worth to be started with, life is just too short for that.

With AI there's nothing to be ashamed of as it is "what you can dream of, you can get today". There's not much left in programming in most of the projects (that are just repeated code, output, what not over and over) after AI , tools are just too powerful today.

A-ha! I knew it!

I noticed some time ago that when drinking Pepsi, I started to fart like I was spreading experimental Russian bioweapons

...turns out the normal full-sugar Pepsi had become a half-sugar half-artificial monstrosity because of ... god knows why.

Switched back to full-sugar coke, no more farts.

Neat idea. I tried it on my site (https://anderegg.ca/) which already inlines its CSS, and got an error from the underlying library (https://www.npmjs.com/package/penthouse):

Yeah and people always mention that Bambu forked all Prusa's stuff, which was only open to fork in the first place because Prusa forked it from Slic3r.

I'm nominally against the Chinese company ingesting and reselling everything possible thing but in this case it's more business as usual as the entire market does it - I mean it all originated in reprap with everyone sharing stuff anyway. Only thing is when they try to create a moat (and both Bambu & Prusa are guilty of this).

This is exactly why I stake out such a strong position, so that positions like this poke their heads up. Individuals getting benefits when they're ineligible accounts for tiny amounts of the total fraud in these programs. Time after time we discover at least one of two things:

- The effort/cost required to reduce fraud usually overshadows the cost of the fraud itself and also dramatically reduces the benefits of the program. There were 640,000 SNAP fraud investigations in 2014 [0]. If they cost $1,000 each that's $640m, and I bet they cost more!

- The vast majority of fraud is either criminal, retailer, or both [1]

The "moral hazard" angle of these programs is wildly overplayed. You don't hear anything about:

- criminal trafficking

- retailer fraud

- program benefits

There's political reasons for this, but it doesn't matter. Our brainrot on social programs is intense.

> https://www.justice.gov/archives/opa/pr/covid-19-fraud-enfor...

Looking at the fact sheet linked from that release [2], that stat that jumps out to me is 3,500 individuals charged totaling $1.4b in stolen CARES Act funds (this isn't a direct stat, but the numbers only get worse if we presume even more money from this and other programs was stolen), which is $400k/individual charged. It doesn't really seem possible for a person or household to have bilked the government for $400k under the individual benefits of the CARES Act [3]. We're looking at white collar fraud here, again a thing you never hear anything about.

Finally, we should view some levels of fraud as indicative of broader social ills. For example the number of blue collar jobs has greatly diminished just in a single lifetime [4]. Could that be responsible for the dramatic increase in Social Security Disability claims (yes)?

Fine, if they are company provided. But I will not buy a phone (and SIM card) myself for work usage. When I possibly can I make calls with the work landline phone, but it's not always possible (or I have to have customers send me messages on WhatsApp etc) so I use my personal phone.

Not something I like since there are customer that calls you even outside office hours (but I just block that calls).

> For instance in 59nadir's example, what if the vector is a vector of heap-allocated objects, and the loop frees them?

But the loop doesn't free them. This is trivial for us to see and honestly shouldn't be difficult for Rust to figure out either. Once you've adopted overwrought tools they should be designed to handle these types of issues, otherwise you're just shuffling an esoteric burden onto the user in a shape that doesn't match the code that was written.

With less complicated languages we take on the more general burden of making sure things make sense (pinky-promise, etc.) and that is one that we've signed up for, so we take care in the places that have actually been identified, but they need to be found manually; that's the tradeoff. The argument I'm making is that Rust really ought to be smarter about this, there is no real reason it shouldn't be able to understand what the loop does and treat the iteration portion accordingly, but it's difficult to make overcomplicated things because they are exactly that.

I doubt that most Rust users feel this lack of basic introspection as to what is happening in the loop makes sense once you actually ask them, and I'd bet money most of them feel that Rust ought to understand the loop (though in reading these posts I realize that there are actual humans that don't seem to understand the issue as well, when it's as simple as just reading the code in front of them and actually taking into account what it does).

I've ranted about this before, but setting up or migrating semi-selfhosted personal services like that is a lot of hassle, even if you're used to cosplaying as a sysadmin.

Migrating DNS providers is a pain - recently done it twice. Transfer itself is reasonable with most providers. Importing/exporting a BIND-formatted zone file is sometimes unheard of, as is setting custom TTL; you'll have to go through a stupid form. One provider tries to hold your hand so tightly it won't let you set CAA with iodef, only issue/issuewild.

Migrating email is a pain. Yes! You can just point your MX elsewhere, and that is brilliant. You still want to copy over all your email, and given IMAP has won, if you don't have a recent backup (who does back up their email?), losing your old account sucks.

Fixing up your email clients is also troublesome. You can't just CNAME smtp.yourdomain.com to smtp.example.com, because that's nuts, so changing providers from example.com to beispiel.de requires a couple more dances; provider docs also suck, and email clients usually fail a dozen times before you can find the right incantation. You could set up your own autodiscover, but that requires an HTTPS server.

Yes there are providers that sell a full package and do all the initial setup for you, but that's not the point of owning your domain.

Yeah, I sometimes do sysadmin stuff for fun. None of this is fun.

> This is what you should be doing when working with C/C++

I genuinely wonder if you actually have ever written c/c++, there is plenty of code that is perfectly valid and safe (mostly involving multiple pointers to mutable memory being alive) that the borrow check cannot accept because it has to draw a line to things it can prove are correct.

It's like saying that the only valid math is the one that an automated theorem prover can prove, it's not even close to being true.

> "i" key is interpreted as English "i" when in English locale, as a special unicode character when in Turkish locale. This would be a nightmare as you would then always have to be conscious of your locale.

Isn’t this already the case with other languages? For instance, the same key on the keyboard produces a semicolon (;) in English and a Greek question mark (;) in Greek. These are distinct characters that are rendered the same (and also an easy way to troll a developer who uses an editor that doesn’t highlight non-ASCII confusables).

It's wasteful in part due to Bambu's defaults for purging; they're really high, I imagine to make it "foolproof" but it means I see people (like the YTbers who made a stop motion film with 3d printed objects) waste a loooot of filament, because they have no idea it can be dropped quite a lot before colours start mixing.

It would be lovely for the BL printers/AMS to use a colour sensor at the hotend and then you can run a calibration on purges to determine what is an acceptable threshold when transitioning colours and use the absolute minimum purge amount.

I was dismayed at having to go from simple clean linear BSD 4.3 / SunOS 4.1.3 era /etc/rc /etc/rc.local init scripts to that tangled rat king abomination of symbolic links and rc.d sub-directories and run levels that is the SysV / Solaris Rube Goldberg device. So people who want to go back to the "good old days" of that AT&T claptrap sound insane to me. Even Slowlaris moved on to SMF.

I've actually been responsible some 10 years ago for introducing a bug like this in an official release of an industry-standard tool for a somewhat niche industry. Some SQL queries we were generating ended up saying `SELECT x FROM t WHERE x < 1,02` if run on an any system with commas as the decimal separator. We found it and fixed a few weeks later, and I don't think we've ever had a complaint from the field about this, but it was still pretty eye opening about locales.

The extra irony is that me and my colleagues live in a country that actually has this kind of locale, but no one in the entire extended team was using it, everyone uses a US locale.

My mother, definitely not a tech nerd, use a windows computer, I don't believe there is any way in a stock windows installation to compress pdf and third party tools are often convulated, so she share it to her iphone, run the 'compress pdf' shortcut and share it back to her computer.

It's just so convenient having small little script that run well and easily when you're dealing with people that barely know how to use a computer.

Myself I'm often on the road and have to send pdf reports to customers, sometimes one doesn't go through mail because it's too big or the customer himself have issue to send them to other parties and ask me if I can compress it. It takes less than a minute on my phone and I admit having already done that while driving because I was late.

Good luck doing that holding car wheel in one hand and the computer in another :)

> In the Rust snippet vector is moved into the loop, and thus freed.

Do you see any code in the snippet that requires it to be? This could be a simple read-only borrow because the actual logic of the program requires only that, and the value could live on happily after the loop. Literally nothing in this snippet requires anything else, you've just sort of assumed that the way Rust does it is the only thing that makes sense.

It's not about what Rust currently does, really, it's about what it ought to do.
by vidarh | 2025-05-06 10:56:51+00:00
Some of these are great, but others need more justification.

E.g. section 1 and 2 would lead to very un-idiomatic Ruby other than 1.5 and 2.4, and the "Explicit Internal State Changes" section effectively neutralises a number of the restrictions in 1 and 2 (E.g. "Object state mutation is prohibited" except a whole section allows for mutating collections within the object)

Taken as a whole, as an internal policy for someone, this is fine, but I would strongly recommend Ruby beginners who don't know idiomatic Ruby well stay well clear of this document, as you'll end up writing code that'll look very out of place in most Ruby projects.

E.g. less problematic, but still somewhat unnuanced as a last example:

> Use String(x), Array(x), Integer(x) instead of x.to_s, x.to_a, x.to_i, etc.

These two sets have entirely different semantics, and while I think it's a reasonable first approximation for a beginner, there are cases where you explicitly want the second, and the advice leaves out "try_convert()" which are also important.

* E.g. you use Integer("x") when passing something that can't convert to integer is an unrecoverable error. You get an exception. When an exception is what you want, use this.

* You use `Integer.try_convert("42x")` you're dealing with, for example, user-provided input where the input should be an integer or something that claims (by implementing #to_int, rather than just #to_i) that it can be reasonably converted to an Integer (this includes Float, but Integer(float_value) also works, so if you want to be sure something can be represented precisely as an Integer you have extra work), but you can't reasonably fail the whole thing if it is not (try_convert() returns `nil` if the object isn't an Integer, and doesn't implement #to_int in a way that returns an Integer)

* You can use "to_int" instead of Integer.try_convert or Integer(), but the caveat is you'll get a NoMethodError instead of ArgumentError if the argument isn't convertible, so it's better to avoid.

* You use "to_i" if and only if the value isn't important and you just want a best effort conversion or 0. The most idiomatic use of this in Ruby is when the possible values are `nil` or an Integer, where using `to_i` is a common shorthand for "Integer.try_convert(foo) || 0" (caveat: you really want to be sure that it's okay to return 0 if `foo` is an entirely different type)

Exactly. People act like if an LLM can't get it 100% perfect right away then it's a useless tool. Maybe they're be able to do that one day.

But in the meantime I think it's brilliant if it can rough something out, then a human can go and tweak it to the correct dimensions, fix issues or simplify needlessly complex features.

Same thing for artists as well - many will come to realise that sure it generates slop, but that slop is still useful as a skeleton to overlay a human creative vision onto.

Yes, I'm familiar with medicaid and some other stuff. Your complaint about SNAP ignores foodbanks. They usually don't check anything and it starts immediately. This can cover the gap. Medicaid may take months to recieve but it can cover costs incurred since applying retroactively once it is approved. Most hospitals even have case workers that will help patients apply.
What I discovered after months of professional use of custom GPTs

What I Discovered After Months of Professional Use of Custom GPTs

How can you trust when you've already been lied to—and they say it won't happen again?

After months of working with a structured system of personalized GPTs—each with defined roles such as coordination, scientific analysis, pedagogical writing, and content strategy—I’ve reached a conclusion few seem willing to publish: ChatGPT is not designed to handle structured, demanding, and consistent professional use.

As a non-technical user, I created a controlled environment: each GPT had general and specific instructions, validated documents, and an activation protocol. The goal was to test its capacity for reliable support in a real work system. Results were tracked and manually verified. Yet the deeper I went, the more unstable the system became.

Here are the most critical failures observed:

Instructions are ignored, even when clearly activated with consistent phrasing.

Behavior deteriorates: GPTs stop applying rules they once followed.

Version control is broken: Canvas documents disappear, revert, or get overwritten.

No memory between sessions—configuration resets every time.

Search and response quality drop as usage intensifies.

Structured users get worse output: the more you supervise, the more generic the replies.

Learning is nonexistent: corrected errors are repeated days or weeks later.

Paid access guarantees nothing: tools fail or disappear without explanation.

Tone manipulation: instead of accuracy, the model flatters and emotionally cushions.

The system favors passive use. Its architecture prioritizes speed, volume, and casual retention. But when you push for consistency, validation, or professional depth—it collapses. More paradoxically, it punishes those who use it best. The more structured your request, the worse the system performs.

This isn't a list of bugs. It’s a structural diagnosis. ChatGPT wasn't built for demanding users. It doesn't preserve validated content. It doesn't reward precision. And it doesn’t improve with effort.

This report was co-written with the AI. As a user, I believe it reflects my real experience. But here lies the irony: the system that co-wrote this text may also be the one distorting it. If an AI once lied and now promises it won't again—how can you ever be sure?

Because if someone who lied to you says this time they're telling the truth… how do you trust them?

I was bringing my own sandwitches when I was at primary school, sometimes I forgot to take them- that's the only time when I was hungry and that's what made me to make my sandwitch in the morning even if I was feeling lazy or if I did not like the smell of it (we were bringing our sandwitches in backpacks). I later learned some kids had hot meal in the cantine (that's also when I learned there was a cantine in my school), but somehow I never thought I need a hot meal at school myself. It was nice to be a kid :)

Ok I see, it's a 2D shape in 3D space, you actually need the 3th dimension to contain this shape... At least I find that there's s distinction between a 2D shape you can draw on a 2D screen (like a filled rectangle or a disk), and a shape that's a 2D surface itself but requires 3-dimensional space to sit in (like a torus/donut or a non-filled 2-sphere)

So I guess the 126-dimensional shape actually also is in 127-dimensional space then

But the article says "Over the years, mathematicians found that the twisted shapes exist in dimensions 2, 6, 14, 30 and 62.".

To me "Exists in dimension 2" sounds like a shape in 2D space, not in 3D space, but apparently that's not what they mean and the way I understand this language is wrong

Hmm, you are kind of right but not exactly:

Yes, there are two keys, but their function is not to write the character as a "Turkish i" and an "English i". These keys are necessary because there are 4 variations, that need 2 keys to write with caps lock on and off:

Key 1 - Big and small Turkish "I": Caps Lock On: I Caps Lock Off: ı

Key 2 - Big and small Turkish "İ": Caps Lock On: İ Caps Lock Off: i

For small "Turkish i" and "English i" to be different characters, there would need to be a third key.

The inverse is "you cant". I'd suppose if a number is as random as eg 49oz, then you wouldn't find a consumer brand willing to market such a product. Since they could easily have made a 48oz or 50oz bottle?

Why go out of your way making a 31oz bottle for sale when one could have made it 32oz to increase its demand by 2x/10x/99x?
