zweifuss··on Love C, hate C: Web framework memory problems
I would claim that:

(interactive labs + quizzes) > Learning from books

Good online documentation > 5yr old tome on bookshelf

chat/search with ai > CTRL+F in a PDF manual

zweifuss··on When I say “alphabetical order”, I mean “alphabetical order”
You mean file9 before file10?

I have some beef with microsoft, that you can only change this at the Computer level, not per user (see registry key below). Also they call it natural sorting for users, but logical sorting internaly. Unify your termini!

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer] "NoStrCmpLogical"=dword:00000001

zweifuss··on Has dystopian sci-fi been wrong all along?
I haven't read that. But the search for immortality is ancient. It's in the Gilgamesh epic; Emperor Qin Shi Huang searched for it, as did many others looking for the Philosopher's Stone. Of the current wealthy researching immortality, I know quite a few without googling: Larry Ellison, Jeff Bezos, Larry Page, Sergey Brin, Peter Thiel, Sam Altman.
zweifuss··on Has dystopian sci-fi been wrong all along?
I would like to know what dystopian books you have read.

I think about 50 years ago there began a slow shift from warnings of overt totalitarianism (1984, Brave New World, Fahrenheit 451) to threats of social fragmentation, economic inequality, corporate surveillance and other indirect forms of control, the resulting loss of individualism and, of course, ecological collapse. These issues seem to remain relevant for the foreseeable future.

I also believe that no one really understands how the world works, not even the elites. Incidentally, this is the most powerful argument for democracy that I know of.

zweifuss··on PHP 8.5 adds pipe operator
It's so dead that 79.2% of all websites rely on PHP to some degree.

zweifuss··on We Tested 7 Languages Under Extreme Load and Only One Didn't Crash
"but it literally does crash and restart" No, think of it not as blue screening and reboot, but as a form of automatic error detection and handling. This keeps the system up and responsive, even if unrecoverable errors happen.
zweifuss··on America Is Backsliding Toward Its Most Polluted Era
Possibly because of the Cold War experience. Also because globalisation is slowing down and we see some reshoreing already.
zweifuss··on We were wrong about GPUs
I imagine you can do this without any reverse engineering of Nvidia's drivers, but §2.3 of the NVIDIA Driver License Agreement makes it hard (not impossible).
zweifuss··on HMD Key – A lightweight, affordable smartphone
Android Go, actually.

Teams, Slack, etc. won't work well (or at all). WhatsApp, Skype only in a limited mode.

zweifuss··on Three-quarters of the land is drying out, 'redefining life on Earth'
Certainly not. But old solar cells that still have a certain lifespan can be obtained almost free of charge by anyone who wants them.
zweifuss··on AWS data center latencies, visualized

Tested with uBlock Origin on Firefox Mobile.

zweifuss··on Swimmable Cities
Full ack. Water quality can be very good. Sligtly dangerours, witch makes it exciting.
zweifuss··on Charging lithium-ion batteries at high currents first increases lifespan by 50%
Initial Litium deactivation is 30 % compared to 9 % with slow formation loading.
zweifuss··on Nuclear reactors a mile underground promise safe, cheap power
Sergei Tretyakov made such claims. https://en.m.wikipedia.org/wiki/Sergei_Tretyakov_(intelligen...

Stasi and green activist contacts are also documented. (Most funding came from fossile fuel orgs/persons, not eastern block.) https://www.dw.com/en/study-confirms-that-stasi-infiltrated-...

zweifuss··on The U.S. Navy's $100M checkbox (2019)
While I agree with most of the assessment, I think that checkbox is fine. Removing the set of motorized haptic control levers and the motorized steering wheel at the brigde is a problem. Had the designers needed to integrate the feedback forces, they could have visualized them on the gui only stations too.
zweifuss··on The curse of the goitre in Switzerland
This might interest you: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3169859/

"The interests of people in the thyroid gland have always been immense because of the widespread prevalence of its diseases. Therefore the earliest references to the gland date back to 1st century AD. The Chinese, Egyptian, Indian, Greek and Byzantine medicines are especially rich in their knowledge on the subject."

zweifuss··on Polish trains lock up when serviced in third-party workshops
Your nickname seems appropriate to me.
zweifuss··on Like Clippy but for the CLI
You could check "Don't show me this tip again". That's why I don't remember it as the main problem with Clippy. I agree that it was a bad idea in the first place to interrupt a user's action. Finding the right time and manner to offer a suggestion is a hard problem even for a human being.
zweifuss··on Like Clippy but for the CLI
Clippy, if activated, always added an unnecessary step in accessing the help file. Clippy was in part bad, because the help file had a mostly useless index, leading to no or wrong answers for Clippy. The content in the help file was additionally less than accurate, it lacked usage examples and a FAQ section that could have been used for recognizing and offering a solution to a question.

The difficult part of creating an assistant is recognizing the users' problems and offering solutions. It's the kind of experience a company can acquire with years of tech support or lots of lab testing. Then it would have to compile that knowledge in an expert system and give it away essentiality for free.

Companies that prioritize development and/or support over documentation shouldn't try to create an assistant for the same reasons. But if you have great documentation, a great support knowledgebase, and support scripts, creating an assistant out of it will someday become as easy as keeping a Juypter notebook running.

zweifuss··on The decline of computers as a general-purpose technology (2021)
Yes, that's how it is. For every reform that would benefit society as a whole, there is now a tiny minority of certain losers with a deeply entrenched lobby against the new and for the old. Be it fossil fuels, health care, banking, peace in the Middle East, nuclear technology, the use of genetic engineering in plant breeding, electric vehicles, and so on.

I don't think UBI would change that, but UBI might have a chance to change the perception of one's job as a bullshit job (they say that's 40% of the workforce).

zweifuss··on Raspberry Pi 5
I just did a quick review on Amazon of adapters ranging from 30 to 120W. Not a single one claimed to support 5V/5A DC. Only a couple claimed 5V/4.5A and they were expensive. 5V/3A is common in the $15+ category.
zweifuss··on Raspberry Pi 5
My Huawei 65W adapter has a detachable USB-C cable. Came with a laptop.
zweifuss··on PostScript’s sudden death in Sonoma
Yes, until about 1995, a new laser printer could have a more powerful CPU and more RAM than a fairly common (even new) office computer driving it. That stopped at about Pentium 100 speed and 6 MB of RAM because normal use cases didn't need more than that.
zweifuss··on Technique for 3D printing metals at the nanoscale reveals surprise benefit
It probably needs several military applications first. For example, you very rarely see transparent aluminum (also known as ALON®) in windows 30 years after its invention, but we wouldn't even be making it, for example for IR missile domes, if its development hadn't been funded by the U.S. Department of Defense.

The next step would then be special medical applications. For example, as a synthetic material for implants. And there you wouldn't want ultra strength, but a certain bounciness and relatively low density.

zweifuss··on Kernighan and Pike were right: Do one thing, and do it well
Microsoft ported OLE 1 to Macintosh, but never OLE Version 2, because Apple guidelines forbid programes to start other programs. Because of that Photoshop had a not supported version of OLE. I don't know if it is still available in up to date Photoshop.

On Windows it works both ways with OLE 2.

zweifuss··on Netscape and Sun announce JavaScript (1995)
Your definition of common sense is not really common. Flash, for example, was one of the very early use cases of an ActiveX control. This unsafe technology was supported by Internet Explorer until the end. The IE11 engine is still an installable part of Windows 11. Netscape Navigator plug-ins also were binary code modules. NPAPI was supported by Google Chrome until 2015.

There were warnings from the beginning (both with ActiveX and NPAPI), but for most engineers, getting things done took precedence over trust issues. Youtube, for example, would not have been possible until much later without Flash.

zweifuss··on The Pentagon’s $52k trash can
The Logitech F710 wireless gamepad used in the Titan was similar to a PlayStation 4 controller and not at all similar to a MS-Xbox-Wireless-Controller. I don't think it was the point of failure.
zweifuss··on The Rot Economy
For me, the Internet was dying in 1997. Ads, scams, and Pr0n were everywhere.

Let's recognize that in not-so-small parts of the world, the Internet is still on the path to becoming ubiquitous, reliable, and affordable.

zweifuss··on We should not let the Earth overheat
Those estimates seem to be outdated.
