Welcome

My name is Arusekk. Not a real name, but I find it the most real for me online. This is a blog where I write about computer programming and some unpopular opinions. Currently some posts are available in English only, some are in Polish only.

Plan 9 setup on OpenWRT

Ever wanted to try Plan 9 but it did not work? Just kidding. My setup involves a Linux router as a file server, a Raspberry Pi 2 CPU server, and a generic netboot config for amd64 terminals (including QEMU). File server on the router means DHCP (of course it does it already; OpenWRT uses dnsmasq), PXE (TFTP provided by atftpd) and finally a 9P server (u9fs; maybe in the future you can run an actual file server, like gefs, with Uglendix). ...

Polish has no articles but it is not SVO

I just found while English is a strict SVO language, Polish is not, and makes use of it. On the example of one of Henryk KrzyĆŒanowski’s excellent translation samples: The brass section was apparently approaching. Orkiestra dęta najwyraĆșniej się zbliĆŒaƂa. But, as it appeared to me this morning, if we change ’the’ into ‘a’, the natural translation would differ by order: A brass section was apparently approaching. NajwyraĆșniej zbliĆŒaƂa się orkiestra dęta. ...

Facebook messenger custom reactions

Well, not exactly custom, but you can basically put any string there. This is a Javascript snippet that makes it possible to change a :hugging_face: into :people_hugging:. You can of course change it to turn nearly any emoji to any other emoji. You can execute it for example by pressing F12 and pasting it in the command line. WARNING: read the code before pasting! if I was a cybercriminal I could take over your account; this technique is called Self-XSS. ...

Tech vs religion

The idea came to me after I read two books one after the other, and they had unexpectedly many observations in common. Hejtoholik (“Hateaholic”) by MichaƂ Wawrzyniak, a Polish artist-mentor-entrepreneur, written using psychological language, and Fear Fighters by Jentezen Franklin, an American pastor (polish translation: “Zwycięstwo nad strachem”) written using christian language. I am going to describe my observations about religion in general, but I will focus on catholic faith, which I believe in, although I suspect most of what I write here will still hold concerning many different denominations, especially those christian and middle east. ...

Rant on TLS PKI

I like modern cryptography. I quite understand some bits of it, since I had an excellent university course on that, and while the rest feels pretty magic, these are my thoughts that should be understood by anyone. My general opinion is that encryption is a mistake in most cases, but digital signatures make true sense to me, and I will focus on them. If someone gives you much data, they know more than you. This is true especially for big integer numbers. Remember RSA? This is the (still widely used) encryption algorithm that assumes that while it is trivial to know n = pq when you know two primes p and q, it is really unlikely and/or computationally expensive to guess p and q from n. ...
