C++: you sure you want to do this? This will either: a) blow your foot off b) be too fast to be measured in micro-benchmarks.

b. B. B. a. then B.

You have chosen to simultaneously blow your arm off and be the fastest code thing on the planet. Congrats. Yes.

I was suspicious as heck of this link, but I thank you for being benign.

My most common typo is gti <random command> and I’m considering to alias it as rm -rf --no-preserve-root /

name your function as malloc() and see to world burn and generate bugs at factorial rate.

Lettme introduce you to ackermann’s function:

int ack(int m, int n) {
    if (m == 0) {
        return n+1;
    } else if((m > 0) && (n == 0)){
        return ack(m-1, 1);
    } else if((m > 0) && (n > 0)) {
        return ack(m-1, ack(m, n-1));
    }
}

You won’t run out of stackoverflows any time soon.

To produce 1 commit, I end up rebasing the damm thing at least 3 times. If there is an problem, it’s at least 2³ times.

volatile int blackhole;
blackhole = 1;
const int X = blackhole;
const int Y = blackhole;

Compiler is forbidden to assume that X == 1 would be true. It’s also forbidden to assume that X == Y. const just means the address and/or the data at the address is read only. const volatile int* const hwreg; -> “read only volatile value at read only address hwreg”. Compiler can assume the hwreg address won’t magically change, but can’t assume the value read from that address won’t.

Please, no, I get flashbacks from my 6-month journey (still ongoing…) of the code review process I caused/did. Keeping PR scope contained and small is hard.

From this experience, I wish GitLab had a “Draft of Draft” to tell the reviewer what the quality of the pushed code is at: “NAK”, “It maybe compiles”, “The logic is broken” and “Missing 50% of the code”, “This should be split into N PRs”. This would allow openly co-develop, discuss, and steer the design, before moving to nitpicking on the naming, formatting, and/or documentation details of the code, which is likely to drastically change. Drafts do work for this, but the discussions can get uncomfortably long and convolute the actual finishing of the review process.

Once both reviewer(s) and the author agree on the code design, the “DraftDraft” could be collapsed into a link in an normal Draft to be mocked next. The scope of such draft would be limited by the earlier “DraftDraft”.

Holy cow.

The day I configured git to use Geany for commit messages with a separate config specifically tuned for this, it improved my life by 300%

~$ cat ~/bin/gitedit
#!/bin/sh
exec /usr/bin/geany -i -s -t -c ~/.config/gitgeany $@

Then in git config: git config --global core.editor "gitedit"

gdb> break before it crashes
gdb> record full
gdb> continue
(segfault)

gdb> set exec-direction reverse

Bugs that have existed for +3 years in a component and are nearly immediately visible to the end user. Oldest source line I touched was from before 2010.

It’s a FOSS project, so wish me luck, as you can now get it in the mail eventually.

I had to run a makepkg today, which now includes my self-written pieces of code in master. So I’m eating my own dog food now, and it’s good. Also, the itch from before has somehow relieved.

Reaper of the VMAs.

I fckd up a git rebase -i today with git commit -a --amend…

Thankfully git reflog allowed me to assemble the branch again … from pieces.

There were no unit tests and previous dev had opened the pandora’s box with half-written implementation. Gasp

C++: The project is now led by university research comitee optimizing essays/second and consists 1k lines of template hieroglyphs.

Until you would have to replace a HDD: +23 hours of nerve racking RAID repair time for 10TB drive at 120MB/s Even with some advanced (like ZFS etc.) system you can’t go around the fact the HDDs are slow.

And when the HDD fails, you can’t read it. It’s toast. Some cheap non-volatile memory devices are like this too, but good ones go into read-only mode and you can at least attempt data recovery from them if no better option is left.

I’m liking that it is possible get cheap+good 1TB NVMe devices for less than 100€. The consumer SATA market for large SSDs (capacity over 1TB) is unfortunately quite dry. I need replacement for HDDs and even if the speed is capped by SATA bus it would be an massive improvement.

I recently switched my default search from Google to DuckDuckGo: Google has begun refusing to find anything while exact same search on DuckDuckGo just works. Google is slower because I have to think+ignore first half of the page due to Ads/SEO crud.
