Blikkentrekker··on 4chan Sharty Hack And Janitor Email Leak
So you were able to find the leak? Because I see reports that it was hacked repeated as fact everywhere on Daily Mail-tier reliable news websites and Reddit posts, but they are all based on “rumors on social media go about that there was a leak” but I've not been able to find the actual leak searching for it. Obviously not many people want to link it but it's also weird that so many people claim to have so easily been able to find it when I cannot.

Finally, I was there and using it when the website went down and this did not resemble an actual hack but technical issues. First there were a couple of hours where the website was up but no posts went through for anyone except occasionally when a new threat was bumped, mirroring the normal pattern of downtime issues that sometimes occur and then it just went down completely. This doesn't really resemble how a hack plays out but looks more like technical issues to me.

Even now, going to the front page, it loads for me, except very slowly and incompletely. This does not resemble a hack but technical issues.

Blikkentrekker··on Add "fucking" to your Google searches to neutralize AI summaries
Correction: That some subset of the people you mostly meet online tries to get rid off.

You'd be surprised how many don't even realize it's artificial, and/or welcome it. The average Google user is most certainly not similar to the average Hacker News commenter.

Blikkentrekker··on Falsehoods programmers believe about null pointers
> In ye olden times, the C standard was considered guidelines rather than a ruleset, undefined behavior was closer to implementation-defined behavior than dark magic, and optimizers were stupid enough to make that distinction irrelevant. On a majority of platforms, dereferencing a null pointer compiled and behaved exactly like dereferencing a value at address 0.

> For all intents and purposes, UB as we understand it today with spooky action at a distance didn’t exist.

The first official C standard was from 1989, the second real change was in 1995, and the infamous “nasal daemons” quote was from 1992. So evidently the first C standard was already interpreted that way, that compilers were really allowed to do anything in the face of undefined behavior. As far as I know

Blikkentrekker··on Octopuses seen hunting together with fish
All my friends say “octopodes”.

Some people on the internet keep saying that that's wrong; I find that very strange.

>because we don't pluralize any other word that way.

Certainly we do “platypodes”, “matrices”, “irides”, “clitorides” and “vortices”, are all quite common words.

Blikkentrekker··on ArXiv now offers papers in HTML format
No, the problem is very easy, referring by page number is simply ridiculous. As well as all those “(<Family Name>, <year>)” citations,

Besides, in HTML one can directly link to the relevant part.

Blikkentrekker··on ArXiv now offers papers in HTML format
Quite so. The font annoys me. This is one of the reasons I hate PDF and why I believe these things should be controlled by the person reading it, not the publisher.

I do not much care what font the auctor finds pleasant to read, but what I find pleasant to read, and this font isn't it, and neither are the colors.

Blikkentrekker··on ArXiv now offers papers in HTML format
Or normal keyboards? Many people can type blind. Some learned to do so while born blind, others became blind after they had already learned this skill.

I would assume that the majority of persons on HN are not looking at their keyboard as they type.

Blikkentrekker··on ArXiv now offers papers in HTML format
I made these arguments two decades ago when I was still in university that PDF is a horrible format because it's purely præsentational, especially for people with disabilities whose software relies on semantic information. LaTeX last time I used it didn't even have a different symbol for uppercase Alpha and A because the glyphs are indistinguishable.

They argued that PDF was superior because the publisher could control how it looked and it looked the same everywhere but the point is that it should not. Things such as font size and line spacing should be at the control of the consumer, not the publisher. This isn't simply blind people but for instance also persons with dyslexia who use particular fonts to make it easier to read for them. Or in my case, someone who simply gets a headache from fronts and line-spacing that is too big. I've also been using darkmode everywhere for so long now that reading black text on a white surface on a screen gives me a headache.

Blikkentrekker··on Linux: Ext4 data corruption in 6.1.64-1
So this is another bug introduced by Debian itself by patching things?

I remember that there was a fairly severe one which was caused by patching OpenSSL I think? But I remember the change they made being fairly weird and no one understood why but it was easy to see that it would introduce a vulnerability.

Blikkentrekker··on Dutch astronomers prove last piece of gas feedback-feeding loop of black hole
In that case how is it a slingshot and a very eccentric orbit?
Blikkentrekker··on Dutch astronomers prove last piece of gas feedback-feeding loop of black hole
I don't understand this article at all. Is it some kind of discovery that gas that exists somewhere can be attracted to a supermassive black hole, or a body with mass of any type? I don't see the relevance to that the gas was once ejected by the black hole; it's well known that mass attracts.

Also:

> Supermassive black holes at the centers of galaxies have long been known to emit enormous amounts of energy. This causes the surrounding gas to heat up and flow far away from the center. This, in turn, makes the black hole less active and lets cool gas, in theory, flow back.

This is a very strange way to word that the immense friction in the accretion disks of black holes creates immense heat and light, is it not? As far as I know, the actual energy black holes emit in the form of hawking radiation is rather very minute and undetectably low with current censors.

Blikkentrekker··on Understanding rapid tendon regeneration in newts may one day help human athletes
Do people even know where to start with this? Is any research even trying to find a way to replicate these abilities in a mammal?
Blikkentrekker··on Setenv Is Not Thread Safe and C Doesn't Want to Fix It
Because the specification of the POSIX shell says that `export` changes the current environment of the running process, not just of any newly started processes.

This is useful to recognize various processes I suppose. I have written code that scans the environment of processes to find particular processes and group them together.

Blikkentrekker··on Understanding rapid tendon regeneration in newts may one day help human athletes
There has been research going on about the difference in reptilian and amphibian regeneration opposed to mammals for many decades now and news outlines always say that this could one day lead to something replicated in mammals. But have any advancements in replicating it in mammalian test subjects, opposed to simply understanding the difference between reptilian and mammalian regeneration ever been made?
Blikkentrekker··on Setenv Is Not Thread Safe and C Doesn't Want to Fix It
No, in many cases one needs to set them interactively.

Consider for instance something as simple a implementing a shell. Such a program needs to be able to set the environment based on user interaction and this change needs to show up in /proc/$pid/env.

Blikkentrekker··on Japan pharma startup to begin human trials of tooth regrowth drug in 2024
The article implies the third set disappears in adulthood.
Blikkentrekker··on Japan pharma startup to begin human trials of tooth regrowth drug in 2024
The article says that the initial plan is children who were born with missing teeth, and then for lost teeth in adults.

The way it's explained suggests these “tooth buds” they use disappear in adulthood however, so I'm not sure how that works.

Blikkentrekker··on Did you know Git was originally created in 10 days?
And many things that exceed existing standards objectively somehow lost out to exceeding standards or inferior standards coming later. The success of software in particular is about being at the right place at the right time as well as interoperability. Plan9 is generally considered a technical improvement over Unix, but where is it, who uses it? Redox can improve or Unix all it wants on a theoretical level, but it will probably never outcompete it due to interoperability and because of that it won't attract the developers to add the necessary features to compete with it.

Linux in particular started because a student made a task scheduler on his home computer with no real goal to make a Unixlike kernel, and it grew into it and it so happened that at the time there was a big vacuum for a free Unixlike kernel. kFreeBSD and kMinix were not yet free at that time, had they been, Linux would have no doubt stayed a hobby project.

Blikkentrekker··on Did you know Git was originally created in 10 days?
I'm fairly certain a lot of very influential software came from the hands of Bill Gates as well such as the FAT filesystem which is still used, the original MSDOS and BASIC Interpreter which made a huge impact.

Of course, that's all mostly because much of that was bundled with the original MSDOS.

Also, in terms of video games, a great deal of innovative techniques and games game from John D. Carmac, which of course also is a result from Id Software pushing it.

Blikkentrekker··on Did you know Git was originally created in 10 days?
> And it's amazing that two of the biggest contributions to the world of software came from the same person.

That's not that amazing at all, because the fame and weight of being the creator of the former led to the adoption of the other as it became the official version control management system on which Linux was developed. — These are not two independent results.

If someone completely unknown developed Git 0.01 in 10 days, it would probably have stayed relatively obscure, and the reason for it's quality is because it became so famous due to being tied with Linux, attracting many developers.

Blikkentrekker··on Third of Japan's 18-year-olds women may never have children: study
Unhealthy in what way? Given that studies repeatedly report that childless persons report a greater life satisfaction? Why is it bad if it goes against “evolutionary psychology”?

Blikkentrekker··on Third of Japan's 18-year-olds women may never have children: study
https://msutoday.msu.edu/news/2023/childfree-study-confirmed...

Apparently it's very normal. On top of that “abnormal” does not mean “unhealthy”, but then again, that's something psychologists very often don't understand either.

Having an I.Q. above 145 is certainly not “normal”, but not a cause for concern either.

Blikkentrekker··on Third of Japan's 18-year-olds women may never have children: study
I would absolutely not as an untrained person try to firefight my own house rather than rely on trained professionals for that, no.
Blikkentrekker··on Third of Japan's 18-year-olds women may never have children: study
Why would people make up excuses? They simply don't want them.

My “excuse” for not having children is the same “excuse” I have for that I'm not a firefighter: I have no interest in it.

Blikkentrekker··on We are not empty: The concept of the atomic void is a mistake
Why would stars hit each other during galactic collisions when stars inside of a single galaxy already almost never hit each other? Apparently reading it here of all the stars in the galaxy, a stellar collision only happens once every 10 000 years.

Interestingly enough, when galaxies collide, the supermassive black holes at their centres do typically merge as their gravity is strong enough to attract each other.

It's by the way not particularly unlikely for stars to pass through other solar systems. Apparently about 70 000 years ago a binary star system flew through the Oort Cloud.

Blikkentrekker··on FreeBSD replaces bubblesort with mergesort on SYSINTs
Okay, but what exactly is 100 times faster when measured? Simply the sorting algorithm? If it not be a bottleneck to something then it doesn't matter much.

I assume the entire performance of FreeBSD hasn't improved a hundredfold by this small change.

> and created monotheist religions to substitute animist religions

I often see this interpretation that monotheism is somehow more “advanced” than polytheism, even Age of Empires suggested so but why exactly? Because Christianity and Islām became so popular?

Blikkentrekker··on Miyazaki has used the art of animation to study the major problem of adult life
It should be noted that “神” can probably better be translated as “spirit” in many contexts, and denotes a wide variety of supernatural beings, which actually makes “spirited away” an interesting choice.
Blikkentrekker··on Miyazaki has used the art of animation to study the major problem of adult life
Titles are very frequently changed, this is because titles are supposed to sound catchy and what sounds catchy in one language often does not in another. Spirited Away in Japanese was also literally more so “Sen and Tihiro's mysterious disappearance. The Vanishing*'s original Dutch title was “trail-less” literally, which sounds good in Dutch, but very poor in English though I suppose “without a trail” would work.
Blikkentrekker··on Why checked exceptions failed
Which is a very obscure language.

Type erasure at runtime simply isn't really possible with full union typing and looking at it as a consequence Ceylon has to box everything into a structure which contains a type tag which is obviously not an overhead a language such as Rust is willing to pay.
