  > Obviously the proper solution is to adjust your system thermal management / power targets,

My point is that I understand the users' complaint and request for a revert, not that I can't address this for my own machines. The proper solution for non-technical people is to ask the expert to fix it, which may include undoing the change if they were never interested in the process finishing faster anyway.

I did solve this problem once upon a time by running the process in a cgroup with limited CPU, though I later rewrote my dwm config and lost the command, without caring enough to maintain the fix.

If the fan was turning on where it wasn't before, it seems like cooling was once happening through natural dissipation, but after your fix it needed fans to cool faster. So the fix saved time but burnt extra electricity (and the peacefulness of a quiet room.)

This is pretty easy to understand IMO. About 70% of the time I hear machine's fans speed up I silently wish the processing would have just been slower. This is especially true for very short bursts of activity.

Could it have something to do with Minnan and Mindong Chinese articles being written in a Latin script, (despite the language name showing in both Chinese characters and Latin letters) ?

The Wikipedia sort for the languages is as I stated above, with Literary Chinese and Japanese between Wu Chinese and Yue Chinese. I explained why it was sorted that way, because radical is considered first. You could not explain why Japanese appeared between Wu and Yue because you insisted and continue to insist that radicals are not used.

I didn't say sorting is never done by stroke count alone. But I have seen radical+residual stroke count much more often than stroke count alone. Probably a result of the content I'm accessing. It's mostly Japanese and not intended for children.

The dictionary and non-dictionary sorting distinction that you make doesn't sound like a real thing. The audience, the country, and the number of items sorted are bigger factors. But you're not wrong in that stroke count is sometimes used alone.

It is sorted FIRST by radical and SECOND by stroke order. This is roughly equivalent to the Unicode codepoint sort if you stay in the basic multilingual plane. The order also puts literary chinese afer wu Chinese, which breaks with a pure stroke-count sort:

中文 - 中 = 丨 + 3 strokes

吴语 - 吴 = 口 + 4 strokes

文言 - 文 = 文 + 0 strokes

日本語 - 日 = 日 + 0 strokes

粵語 - 粵 = 米 + 7 strokes

Note I work for Google and I've contributed to Chromium, though I'm not necessarily an expert on Chromium forks.

1. Google Chrome

This is offical Chrome you download from google.com and also comes on ChromeOS devices.

2. Chromium

This is what you get when someone builds Chromium from the official repo without access to confidential source.

Source is confidential for various reasons, and some code that seems should be confidential actually isn't, like Android-for-ChromeOS integration, some of which is here: https://crsrc.org/c/chrome/browser/ash/arc/

3. Ungoogled Chrome?

This seems a contradiction of terms. Only Google can build Chrome, so they are not likely to e.g. set Bing as default or remove Google password manager support.

4. Ungoogled Chromium?

A particular project run by a particular team which forks Chromium and removes pro-Google behavior and settings.

5. Googled Chromium?

I don't know the original context of the use of this term, but possibly this just refers to official Chrome.

Chromium is merely Chrome with only the open source parts. Chromium components are still implemented in a Google-controlled repo. So it has Google-oriented features and defaults.

This is the default font of my browser-based terminal emulator, http://github.com/google/werm, along with a handful of other retro fonts (uses the int10h.org ttf's--converted to bitmaps--which I suspect has all the same characters as Neue)

2년 전discuss

IMO it still looks rather nostalgic. I do remember using cmd.exe or command.exe in Windows 95 and later and this being the default (but it would different if you had a different legacy code page set, IIRC). Of course cmd.exe just rendered the pixels as-is, no emulation or retro effects.

Yes, let's take dozens of terminal emulator projects out of maintenance mode so app devs can individually and capriciously overload my shift and escape keys, because modern.

  > Context: Bitcoin miners have just adopted a 50% pay cut for themselves.

Miners don't decide the consensus rules. The nodes validate blocks, and the miners generate them.

The halvening timing was coded a long time ago, and in order to change it, the nodes would need to adopt the new code by installing updated clients, and at that point, you have a hard fork, because there will be nodes on the old rules, either accidentally through not updating or intentionally through using a modified core distro, and you have the new rules' valid blocks is a disjoint set from the old rules'.

The new rules' block set being a subset of the old rules' is a strictening of the consensus rules. A strictening consensus scheme is a soft fork and can keep the network in one piece.

So, there is no real way for the miners to avoid the halvening without a hardfork and a great risk to the network.

Some say hunky dory comes from "honcho doori" or 本町通り (personally I don't see how ki can come from cho)

I wish I knew awk as well as I know perl, since then I wouldn't need to hear recommendations for CPAN modules and spurious style prescriptions.

2년 전discuss

Perl has the advantage of only having one implementation, unlike sed and grep (e.g. BSD or GNU) and /bin/sh (can be one of many POSIX shells), so upgrading this pipeline to 100% perl is safer in some respects. The example in the article is light on details so it's hard to comment very deeply.

I have heard snarky Perl putdowns ad nauseam at work and on HN and may have regretted using it a handful of times but I can say worse or similar for other popular tools, languages...

2년 전discuss

If we're going to talk about unnecessary extra processes like useless cat, we should merge the head and grep commands into a sed, and possibly just merge everything into perl:

    <access.log sed -n '/mail/p; 500q' | perl -e ...

If perl is processing the file line-by-line then filtering lines by regex and stopping at line X is trivial, and you don't even need sed.

This is asking a lot, but if you enjoy that, I would be thrilled if you could do the same for some of my C projects - nusort and werm under github.com/matvore.

Sounds like some interesting case studies. Could you share some?

I should rewrite this as - if I find a leak that I accidentally introduced, I will refactor in the process of correcting it, to make the mistake harder to repeat and the correctness easier to confirm.

There are non-language mechanisms that help code run safely, like Wasm, which is a sandbox. Also msan and asan should be used more.

Thinking that changing the language is the right way to fix all the problems you mentioned still seems like a premature assumption. The fact that 100% perfection is worth pursuing at all costs is theoretical and you could be losing things more valuable in the process - e.g. FFI bindings suck, and the added fragmentation in having so many languages in the craft is a pernicious cost with a multitude of aspects to it.

Don't worry, we enjoy that kind of stuff.

I usually put all the resource freeing at the end of a function under a goto label, or only a few lines within the allocation, so it's easy to visually confirm everything is cleaned up. The way this commit frees the resources inside of if blocks is not how I would have done it. And if I find I let a leak in the code I usually refactor to make the correctness more obvious.

In this example, the fact that m3_ParseModule takes ownership of the wasm pointer is very tricky. It looks like there is still a leak but there is not.

If you store the number of zeros as value z, computing z+1 is O(log n) in the long run for unbounded values of z.

3년 전discuss

If you define predictable as computable with finite memory, it is correct.

If you have finite memory, you have a finite number of states and will eventually return to a previous state. In your example, you eventually will run out of memory to track the number of consecutive zeros.
