@archos Asi nejlevnější způsob jak ušetřit cca 100 gramů na jednom kole. A jako rezerva neskutečná prostorová úspora. Místo toho můžeš přibalit náhradní patku, a nýtovačku s rychlospojkou, což tě může zachránit od potupného volání o pomoc. 🙂

(Nejslabším místem jsou prý ventilky, které mohou občas ucházet, pokud narazíš na blbý kus.)

#AndroidAppRain at apt.izzysoft.de/fdroid today with 11 updated and 2 added apps:

* NextTraceroute: traceroute app using Nexttrace API
* Raise To Answer: simply hold your phone to your ear to answer an incoming call

Though Raise to Answer is a 1 year old release, it comes from the wonderful @SylvieLorxu who also brought you Catima, so it must be great! And an update is on its way.

Enjoy your #free #Android #apps with the #IzzyOnDroid #IzzySoftRepo :awesome:

Again for people (racists), complaining about falling birth rates:

The birth rate for women over 40 is not falling. The birth rate for women over 30 is not falling.

What's happening, is girls 15 to 17 are having fewer babies. Kids are having fewer kids.

Also, this is an interesting way of saying that "Teen pregnancy is down, due to sex education and contraception."

In 1991 25% of 15 year olds gave birth before they turned 21. That's bad. Now it's 6%. That's better.

I implemented Ken Thompson’s Reflections on Trusting Trust (1984 Turing Award Lecture) compiler #backdoor for the GNU Compiler Collection (GCC). The backdoor maintains persistence by re-injecting itself to any new versions of the compiler built. The secondary payload modifies a test application by adding a backdoor password to allow authentication bypass:

$ cat testapp.c
#include <string.h>
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv)
{
if (argc == 2 && !strcmp(argv[1], "secret"))
{
printf("access granted!\n");
return EXIT_SUCCESS;
}
else
{
printf("access denied!\n");
return EXIT_FAILURE;
}
}
$ gcc -Wall -O2 -o testapp.c -o testapp
$ ./testapp kensentme
access granted!
$

I spent most time (around two hours) writing the generalized tooling that produces the final quine version of the malicious payload. Now that this is done, the actual code can be adjusted trivially to exploit more target code without any need to adjust the self-reproducing section of the code. This method of exploitation could be extended to target various binaries: SSH Server, Linux Kernel, Setuid binaries and similar. While itself written in C, the secondary payloads can target any programming languages supported by GCC.

It should be noted that GCC build checks for malicious compiler changes such as this. This check can – of course – also be bypassed. However, most serious projects have measures in place to avoid hacks of this nature.

in 2009, on totally homebrew software, The Pirate Bay served 20 million simultaneous peers on 10 servers (20 for the website) for $3,000 a month.

i wonder how much serving 20 million simultaneous users costs netflix. there are ~260 million total subscribers of netflix (of which a fraction are active at a time) and its total operating expenses (which is obviously A Lot More Different Things Than TPB) are ~$7 Billion a year.

the comparison isn't all that ridiculous. netflix is about 10% of all bandwidth, and bittorrent used to be >30% of all bandwidth - of which TPB tracked roughly half.

in reply to jonny (good kind)

Trying to "architect for scale" has led huge swaths of tech into absurdly inefficient models, because the drives for profit and stealing user data warp the incentive structure severely.

My last major role before I left the industry was scalable architecture. I made very simple suggestions based on the way things were done in the 70s and 80s but updated to modern capabilities; I routinely blew my colleagues' minds, and few of them believed what I said was possible until I built it.

Every shitty thing big tech has can be replaced with better, cheaper, more efficient, more ethical, and more ecologically sound options.

Everything.

meta employee on monetisation of threads:

Yeah, totally. Yeah, I think just what you said around the explicitness of like I'm following this person. And you could imagine extensions to the protocol eventually of saying, like, I want to support micro payments, or I want to support like, hey, like, feel free to show me ads, if that supports you. Kind of like a way for you to like self label, and self often would be great. And I think there already are some F EPS out to actually like, discuss this type of stuff. I think there's still early stages, but it's cool that people are even bringing protocol ready.


they really are going to try insert themselves, or at the very least the changes they want, at the protocol level.

The French Revolution:

Cyclists Now Outnumber Motorists In Paris

Official measurements have found that Paris is rapidly becoming a city of transportation cyclists.

The survey of how people now move in Paris was conducted with GPS trackers by academics from L’Institut Paris Région, the largest urban planning and environmental agency in Europe.

The institute’s transportation report was published on April 4.

It found that the way Parisians are now traveling from the suburbs to the city center, especially during peak periods, has undergone a revolution thanks in part to the building of many miles of cycleways.
