What Hacker News says?
Wikipedia is a great example of a web site that has resisted the trend! It is a pretty ideal democracy for those of us whose ISP or nation-state[0] doesn't prohibit us from viewing it. There was a project similar to Wikipedia, but for semantic data. It lasted for a little while before being swallowed up by Google and shut down[1]. Granted there are some alternatives, but after investing some time working with freeba…

HN discussionHere’s a blog post I wrote recently on a similar topic: https://www.tablix.org/~avian/blog/archives/2019/02/google_i... On my website, the Google index coverage is clearly falling with age of the content. According to the Search Console only about 60% of my posts from 2006 are indexed.

HN discussionSeveral years ago I made jsonmerge, a Python library for merging standard JSON structures. The rules for resolving conflicts are encoded in a standard JSON schema document that is extended with some (non-standard) keywords. https://github.com/avian2/jsonmerge https://www.tablix.org/~avian/blog/articles/talks/tomaz_solc...

HN discussionBack around 2001 I made Tablix ( https://www.tablix.org ). It was my first larger open source project. Back then the faculty I was studying in had some really inconvenient timetables for students and I initially made Tablix to show that better scheduling of lectures was possible. It used a parallel evolutionary algorithm and was written in C. Code and everything else is still on-line but it's been abandoned for a lo…

HN discussion> We also have webmentions, so, if bloggers start using it, it will help us find other's blogs. My informal research [1] shows approximately zero adoption of webmention. For 44 blog posts I have written in the past two years, I did not have a single external link to a host that would support it. [1] https://www.tablix.org/~avian/blog/archives/2020/01/checking...

HN discussionIn my experience IPv6 support in home Wi-Fi routers is still hit or miss. I recently had to replace a new TP-link router because some wireless devices refused to get a IPv6 address due to failing duplicate address detection (it was some kind of multicast issue as far as I could see) The router in question got several firmware updates where changelog mentioned an unspecified "IPv6 fix", but none fixed the issue for m…

HN discussionI found this project a while back when I was searching for information on how to drive lavet stepper motor[1] inside these kind of clocks[2]. My project is similar in a way that you have to manually drive this motor, idea is to convert existing 12-hour clock to 'week' 168-hour clock. Hour hand would make full rotation only each 168 hours, showing current day of the week and approximate part of the day. Very cool pro…

HN discussionI've just done a bit of googling and this guy https://www.tablix.org/~avian/blog/articles/galaksija/ Has designed a replica system, with some minor mods to allow for newer easier-to-get logic chips, and better compatibility with newer Z80 CPUs. He offers up the whole design for download - so anyone should be able to build one. I've bookmarked it... I'm definitely interested in making one to add to my retro collectio…

HN discussionThis reminds me of an old ViewSonic LCD monitor I have. It occasionally corrupts its EDID memory for some reason, which causes the computer to not recognize the monitor anymore. The procedure to restore it sounds similarly weird. You plug and unplug video connectors, the monitor power and boot/shutdown the computer in a certain sequence. I didn't believe that worked when I first read about it. I've done it several t…

HN discussionInteresting. A while ago I designed an OLED display shield for Arduino. Those displays also have a controller IC bonded to the flexible PCB and encased in transparent epoxy. I never noticed any sensitivity to light. http://www.tablix.org/~avian/blog/articles/arduino_oled_shie... I do remember that they were however pretty picky regarding the reset sequence (something the datasheet warned about several times).

HN discussionMy first thought upon seeing this is that I was not aware that Firefox sends this kind of data to Mozilla. Under "how is the report created" [1] it says that "Firefox automatically collects information [...] unless users disable this collection". This seems to be in conflict with Mozilla Telemetry FAQ [2] that says that data collection is disabled by default for release builds. In fact, on Firefox 50.1.0 on Debian I…

on “Firefox Hardware Report for Web Developers”For the eMMC, quite probably. The BBB Rev B BOM lists a Micron chip that tops out at 30MB/s read and 6.6MB/s write (pretty close to measured). The BBB Rev C BOM lists Micron chips in that range but also lists chips like the Kingston EMMC04G-M627 which is capable of 250MB/s read and 25 MB/s write. This link seems to indicate that the Rev C is around 2x faster on eMMC. https://www.tablix.org/~avian/blog/archives/2017/…

on “Results of 500 MicroSD Benchmarks on SBCs”According to something I read somewhere. The ZX81 floating routines did incorperate some unique math: (2^32) - ((2^32)-1) did not return 1 And the group of Cambridge mathamaticians that wrote the ROM turned out to be one man.

on “The ZX81 Turns 40”Circa 2000 I was using a Compaq Contura 4/25cx laptop with Debian Slink, 2.0.36 kernel. It had a 486 at 25 MHz and 4 MB RAM. I also got a parallel port Ethernet adapter from the same dumpster dive. Even with Slink installing with 4 MB RAM required some special care. My notes from the time say it took one and a half minutes to boot. There existed a driver in XFree86 for the funky Compaq AVGA graphics so I could use X…

on “4MB Laptop How-To: How to put a “grown-up” Linux on a small-spec laptop (2000)”Is it just me or did we actually start regressing in terms of moving things off IPv4? A couple of years ago I had a working IPv6 connection at home with a static /64 delegation. I had full IPv6 connectivity at work. Since I had IPv6 connectivity on my laptop ~90% of the time I actually moved a lot of my own private services to be IPv6 only, since that helped a lot with the usual background of port scans and other ra…

on “Android’s IPv6 Is Still Broken”Another case I've seen where TCP checksum failed was in old Eee PCs. There, the TCP checksum check on incoming packets was offloaded to the network interface. Unfortunately, some Linux driver and/or hardware bug occasionally corrupted the packet payload after the check passed. The workaround was to disable the hardware check. https://www.tablix.org/~avian/blog/archives/2010/10/eeepc_no...
