A roof window. Really, two people came in, installed and another team fixed the ceiling around, I painted it around. Now I have more light in the attic. Temporarily I had to move my "goatpen" to the room below, fortunately I have permission to keep all my retrocomputinng stuff there temporarily...

And that's why I don't own a smartphone... or better I'm not owned by smartphone. The idea of the WWW was to get out of these company-controlled walled gardens CompuServe, AOL, Prodigy, Minitel, TG and other sold. It just was no matter what is used to process the incoming data, it was important...

Me when I explain Linux to my Students: "With complete desktop environments, we can see that Linux machines have a very modern-looking GUIs." Also me, on machine using to show examples during the same course: This environment is called TDE and is a very outdated DE based on KDE3, I use this...

Although at the start of pandemic conditions the vaccine initiatives were going quite well, currently I would be VERY alert about buying it right off the batwhen it appears. Every day we have news from companies that they're going to invent a vaccine "in a moment" or they are "doing final...

The cardboard wears in a form of fibers which accumulate on the outward parts of the "bearing", filling it. This works quite efficiently, only add the solution and tighten the mounting. After 6 or 7 attempts it looks like there is no need to tighten as it enters some kind of "steady state" of...

What I should do during the lockdown: - Work on my thesis, - Finish writing my papers, - Perform final computations for research (this is no way quick, a few weeks using 64 cores and 128GB of RAM!), - Maybe send a few evolutionary programming papers to review or even publishing, they are "in...

Commodore 64 Web-it, it's an embedded PC branded as Commodore 64, released in 1998 as an "Internet terminal" with embedded Windows 3.x and CCS64 emulator. Unfortunately someone put a wrong type of RAM to it before. As a consequence, encoder and ROMs blown. Bad, bad, 16MB of ROMs! Generally, a...

Generally I don't have a motivation to do much recently, but I bought an unknown old computer to my collection. So last month, I bought a Texas Instruments computer, only because I find these machines interesting inside, it was not expensive and I have a few machines of this type in collection...

So this is not a specific project, this is because I had a problem in Linux and I had to solve it. In fact, it is an overgrown Perl script which, started as a 5-minute solution, a few hours later transformed into an application with its own config file. So there are these cheap MP3 players which...

I'm from Poland and I mentioned a epidemic in Wroclaw. So the general events were (this is both from "official" documentation which shows a bit flattened story and stories from my friends who lived there with families): 1. Late May: Patient zero returns from abroad. 2. May-June: He is diagnosed...

In 1960s we had a small epidemic episode in one city, when a diplomat whose vaccine didn't worked brought a smallpox. In less than a few days, all airplanes have been grounded, all trains stopped and all transports had to pass disinfection. All incoming roads have been equipped with check points...

A Dell M4800 notebook. I was looking for a new notebook for a long time and I just couldn't find one only because these are not sold as "notebooks" but "mobile workstations". Why? No idea, maybe because they weight more than 3.5kg? I finally hunted down version with this magic sticker "ME...

Recently I got a 8 year old Dell notebook with i3 CPU with one small issue - a blown diode preventing it from powering on. Because this computer must have an up to date BIOS not to overheat in Linux (yes, this thing in which video chip controls overall cooling), I found Dell website deleted it...

No way these tests would even work for plastics! Too much time, too complicated tests not to go into thermal-based deformation. I was thinking that material/tribological parameters are accessible somewhere. Is the coating penetrating or not, is also characteristics of coating. Penetration of...

In my field (steel), unfortunately these are usually practical measurements. We just measure things after x contact cycles (x like 5000, 1000, 2000, 4000, 8000 etc.) and with this + stresses and distances from simulation of the same process that was measured we find material parameters for...

About the wear, generally my knowledge is more in steel than polymers, but, well, this is still a friction. This is really simplified. 1. Most important factors we deal with it are: Normal stress, distance when in friction and, negatively for wear, hardness. These 3 factors make something called...

Just a quick question about this coating: Is it applied during extrusion or is it applied after? If after, how penetrating is it (is it?)? This will shed some light into wear predictions I roughly made.

The final repair log of Soviet microcomputer (cumulative version + some information what to expect in Soviet systems). I will use western names of chips for better understanding. This may sound sick, but I just like doing these diagnostics. Probably a better version of this text will get to my...

Recently I bought a Soviet microcomputer. It has been probably made in Moscow plant, designed in 1980s, but made until 1990s, my unit is from 1991, when it was sold either as a TV game, or as some kind of hobbyists tool. The computer is 8080-based, has some amount of 8255 for I/O and a 8253...

I have finally built my tester software on Windows. I had a small, trimmed-down Qt 5.5 distribution made in 2015, especially to fit under 10MB for a whole distribution when compressed (it is now almost 6MB). It runs! It does not try to write config files to C:\~\.config... It creates...
