No, you are not a billionaire because you're a genius.

You are a billionaire because you're a heartless, predatory sociopath and capitalism exists to reward heartless, predatory sociopaths.

According to all known laws of DNS, there is no way a fedi instance could be hosted on an .ARPA domain.
Even if you get ahold of a domain like this, it should only be used for PTR records - right?

The instance, of course, federates anyway - because DNS doesn't care what humans think is impossible.

in reply to Elias Mรฅrtenson

A really, really bad idea. As someone who worked at the first site on the early ARPANET at UCLA and worked on the original ARPANET protocols and continuously going forward from then, I assure you that doing this will cause you nothing but grief down the line. You can play games with DNS but eventually you'll get bitten. Trust me on this.
in reply to Lauren Weinstein

Bah. All that happens is that you get a bidirectional self-referencing host. Nothing to see.

But, it's not very helpful for humans....

in reply to Richard Levitte

Gotta be aware, though, that you're often not in control of "your" .arpa zone. Your operator is, and some refuse to delegate it further downstream.
in reply to Leszek

fun fact, LE won't give you a cert for .arpa -- very few actially will. LE cites[0] an RFC[1] for this decision,

> In particular, the "arpa" domain is not to be used in the same manner (e.g., for naming hosts) as other generic Top Level Domains are commonly used.

No RFC2119 keywords are used in this recommendation, though, and nothing strictly forbidding experimentation.

oh, you actually managed to find an RFC that suggests against this! I tried and came up empty before.

wrt LE - it at least errors out properly! i've tried a variety of other certificate providers and most of them have errored out in a terrible, unverbose manner. I'm describing this in detail in my upcoming blogpost.

friendica (DFRN) - Collegamento all'originale

On Unix and gaming and SIGINFO


I used #Linux a bit in the days when Slackware was recent, then a friend of mine suggested #FreeBSD (4.7 at the time) and it was love at first sight. After that day, I used FreeBSD on all the servers I am the admin of, and also on my office desktop PC. Still very happy about my choice.

At home, on the other hand, I always needed to keep Windows to cater my gaming habit (no, I don't like dual booting at all, as I often game for a short time while keeping tens of other programs open and ready to use afterwards). Resorting to CygWin to have Unix tools, which I later substituted with WSL 1 (WSL 2 doesn't properly support IPv6 and also it occupies Hyper-V and thus forces VirtualBox in "turtle mode", so it is a no go for me), happily enough for a couple of decades.

Enter Steam creating Proton (out of Wine), making gaming on Linux a common and accessible thing almost overnight (of course it was possible for a long time already, but mostly retro-gaming and via emulators).
So, as an experiment, in the desktop PC I keep at my significant other's home I decided to try and avoid Windowsโ€ฆ I tried FreeBSD for a couple of days, but running Proton on my nVidia 1070 card was very difficult (if at all possilble, I wonder) so, contrary to my convictions, I tried Arch Linux (mainly because it is the one Steam Deck is based on, and the fact that AUR is very similar to the FreeBSD Ports I love and use daily) andโ€ฆ even if #ZFS (I filesystem I cannot do without, ever) is not officially supported and using it via DKMS is a bit of an hack, that only took me 2 hours to conquer and from there it was all much smooth and easier that I dared dream. In only a couple more hours I had everything working at first try, all "by default" and with no need for extra configuration, including things like: nVidia with 3D and CUDA support, USB webcam, Wi-Fi printer/scanner, Bluetooth USB dongle.

I am impressed. 2024 might really be the "Linux on desktop year" as some say, for sure it was for me (at least in this PC, I'm still not migrating the existing Windows setup for now โ€” but someday I will).

Now, ironically, the thing I feel absence mostly is control-T support in the terminal, which on BSD sends a SIGINFO which makes most programs print a status report on stderr. It is something that on Linux wasn't included "mostly out of laziness" as reported by Theodore Ts'o in 2014, but is still missing.

I am of course using FreeBSD on all the servers and hoping that FreeBSD will catch up on ease of use on the desktop to change to it again, but right nowโ€ฆ I like using Linux better than Windows+WSL. ;-)

in reply to Lapo Luchini

it's amazing that you "started" with modern Linux distros on Arch Linux. Did your experience with FreeBSD help in any way in that regard?
in reply to Magitian

(Sorry about late response)
I'm actually not sureโ€ฆ there's also the fact that I end up doing some devops on RedHat for work and had some past Ubuntu experience on Windows WSL too (I recently switched to Arch also on WSL).
I don't really like systemd, but in the end I don't hate it as much as I thought and I will not remove it from the system (I'm not even sure if that's possible); what I really like is that packages are (IMvHO) "properly updated" just like on FreeBSD, I really really dislike Debian approach "old is more secure" (which is not, IMHO, and sometimes is even spectacularly worse just because of that approach).

Intel's Pentium processor (1993) can compute sines, logarithms, and other special functions. To do this, it has a ROM with 304 floating-point constants. I reverse-engineered this ROM and extracted the constants. You can see pi in the ROM, binary 11.001001..., encoded in the transistor pattern. 1/n

This image shows the grid structure of the Pentium's constant ROM. Floating-point numbers have an exponent part and a significand part. In the decimal number 6.02ร—10^23, 23 is the exponent and 6.02 is the significand. The ROM is similar, except in binary. 5/n

In my experience, most people model security issues as broken windows or loose locks, something easily fixed with some care and attention.

On the other hand, most security issues are better modelled as missing structural beams or sinking foundations, flaws that compromise the integrity of the entire structure and the safety people around and within.

in reply to Sarah Jamie Lewis

Security design sometimes seems like a "Unwinnable by Design" scenario in a game where an early incorrect choice leads to a situation where it's impossible to win or rectify conditions in order to win.

Having to start all over from the ground up is rarely favored by management

Investors favor just patches that build technical debt & postpone the inevitable pain of the next data breach, system crash, or ransomware hack.

in reply to Sarah Jamie Lewis

I used a variant of this metaphor a fair bit at my last work - calling some of the problems with our modelling procedures (which were the core of what we were selling) "rotten foundations". It definitely clarified the situation for some people. But it also didn't make the approach to the problem change, as far as I could see.
