1. 2021 timeline

    2021 ended so let me try to mark some interesting moments.


    • Started looking for a new flat. This time to buy not to rent.

    • As kind of experiment I started working on I/O plate for APM Mustang as it never had one. After several hours and versions finally I got something usable. Not perfect but good enough.


    • Online FOSDEM happened. It was the best online conference so far.

    • Friend found me a nice flat. Went, saw, decided to buy.

    • Jon Nettleton from SolidRun asked do I have any interest in a HoneyComb. We discussed and few days later I got HoneyComb at home. Bought things like case and ram for it, used spare nvme and got it working. I use it as build machine for countless projects.

    • Replaced old Netgear router with EspressoBin. I got that SBC from a friend, printed 3d case and sorted out fresh firmware. Now it boots straight from SPI flash and reads operating system from microsd card.

    • After several discussions with developers I wrote how AArch64 perception change when all you used are SBC (compared to being used to AArch64 servers).


    • Another ‘let me explain’ post. This time on U-Boot and generic distro boot as it turned out to be hard to understand/decode for some people.

    • I got an offer of Ampere eMag system. But due to my flat move and shipping/customs issues nothing came from it.


    • Bought flat. Agreed with previous owners on moving date. They started painting walls.

    • Five years at Linaro passed. Still waiting for that glass award.

    • I wrote one tweet and it was enough to get extra AArch64 nodes for Opendev CI.

    • I got “Mars 2020 Helicopter Contributor” badge on GitHub. As one of ~12000 developers.

    • First dose of COVID-19 vaccine.


    • Moved to my own flat. With help from my friends and moving company. Still have a few unpacked boxes.

    • As my daughter had 3 free days in a middle of a week we went for nice trip through museums.

    • Spent some time on designing new structure for home network. EspressoBin got replaced with very small x86-64 system (4 “igb” network interfaces). Finally reached 1Gbps speed on home link.


    • Organizing my new home. Looking for good office furniture ended with buying VS 901 desk and organizer.

    • Second dose of COVID-19 vaccine.


    • Got two Sharp Zaurus palmtops: SL-5500 (collie) and SL-5600 (poodle) from a friend. First model was a device which brought me to working full time on FOSS.

    • My 13 years old daughter asked me what “that huge phone with printer” she saw in anime was. Took me a moment or two to find out that it was fax machine…

    • Crashed my car. No one got hurt. Insurance paid what they had to and I later sold what was left of the car.


    • Vacations! Rented Opel Astra combi and we went for a tour. Met some friends, visited new places (and some old ones). Good time.

    • Friends managed to organize demoscene party in COVID-19 times. So I went to Katowice, Poland and spent great time at Xenium 2021.



    • Left some projects maintained by Arm employees. Open source with closed development process is not something I am fan of. Especially when there is no serious review done on code contributions.

    • I got information that moderators on “Arm Software Developers” Discord are not fans of my comments there. Went through history, dropped most of my posts and left server. Was asked to go back some time later. No longer taking part of conversations there.


    • I was positive! Too bad that it was result of COVID-19 test. 2 weeks of isolation as a result. Boring time with flu-like symptoms. Friends handled my shopping needs.

    • Migrated from Pocketbook Touch HD to Onyx Boox Poke 3. Just to migrate to Onyx Boox Nova 2 three weeks later. Reading books on 7.8” screen is the other experience.


    • Polish demoscene became official Polish cultural heritage.

    • Wrote post about 25 years of using the Internet.

    • Started playing with configuration of my router to get native IPv6/IPv4 setup working. Took far too many attempts and curses but got it done (in 2022).

    • Third dose of COVID-19 vaccine (this time Moderna instead of Pfizer).

  2. My E-book readers

    During last days I had discussions about devices to read electronic books. You know: e-book readers like Amazon Kindle, Pocketbook. I am unable to count how many of them I bought and which models. But I know which I used.

    Very old times

    Long, long time ago I had Palm M105 and then Sony Clie SJ30 palmtops. Used both to read some electronic books. But small screen made it not comfortable.

    First try

    In 2011 I wanted to check how it feels to read e-books on proper e-ink device. Borrowed Amazon Kindle Keyboard from one of my friends and it was good.

    Month later I was in USA on Linaro Developer Summit and bought myself Kindle Keyboard. And got Kindle ‘no touch’ one too. First one went on shelf quickly as I used smaller one more often. Still have it — in storage now as battery finally gave up.

    Amount of books I bought and read in electronic form quickly passed amount of paper ones.

    Upgrading Kindle

    Amazon released e-ink device with touchscreen: Kindle Touch. So I bought it on next US visit (another Linaro conference). This time I also got few devices for my friends (no customs == profit) and sold my ‘no touch’ one.

    Then Kindle Paperwhite on next visit. Screen backlight was huge step. Reading books in buses, planes, trains became comfortable.

    I had one or two newer Kindle Paperwhite devices but for short time.

    E-Book subscription

    In 2015 I gave Kindle Paperwhite to my mother with some books on it. She enjoyed using device but there was a problem with selection of content…

    At around same time Legimi started their e-book subscription service. So I bought Inkbook Obsidian from them and gave my mother as Xmas gift. After some training she became a fan of both service and e-books.

    Goodbye Kindle, welcome Pocketbook

    At some moment Legimi started tests of ‘one account, two readers’ offer. I decided that it is good time to change device. Sold my Kindle Paperwhite and bought Pocketbook Touch Lux 3 instead.

    New device allowed me to use subscription on two e-book readers == less money spent on buying books.

    Few months later I had to buy another device as my daughter took Pocketbook from me and started using it. So I bought Pocketbook Touch HD for myself. And another Legimi subscription ;D

    This was also first e-book reader where I started experimenting with software. Coolreader is nice alternative to original reading application. My favourite option was “ignore publisher formatting” so each e-book looked the same. Of course if it was properly done which was not granted.

    Let go Android with Onyx

    Time passed, I cancelled my Legimi subscription in meantime. And PB Touch Lux 3 one day decided to not refresh screen. Like at all. Dead.

    So Mira got Pocketbook Touch HD and I started looking for something new for myself.

    Asked friends, did some research, watched countless review videos. And decided on Onyx Boox Poke 3. Still 6” 300dpi screen but with all fancy backlight things and Android 10.

    Did not even got used to it and replaced it with Onyx Boox Nova 2 from one of friends. 7.8” screen made a difference especially with pre-formatted PDF files.

    FBreader works great on it and allows to use OPDS catalogs directly from device. And amount of configuration options beats everything I used before.

    I miss one thing (compared to Kindle or Pocketbook) — there is no way to send e-books via e-mail straight to the device.


    During those ten years of using e-book readers I have read countless amount of books. On trip to San Diego I have read above thousand pages on plane (one s-f book series was hard to put away).

    Bought hundreds of books in electronic form. And just a few paper ones just because they lacked any other form. I also feel unable to concentrate while reading paper ones — have to hold them in a way to not close etc…

  3. 25 years of using the Internet

    Twenty five years ago, in 1996 year, I failed exam for Computer Science studies. And went for Automation and Robotics instead. Next five years were funny, tough, hard and interesting. All at once as it is with studies.

    And I got access to the Internet there.


    One day during walking through university buildings I went to not visited yet corridor. There was a group of people sitting in front of some weird terminals. Turned out that those Hewlett Packard 2623A machines offer access to the Internet. All I had to do was to knock the system admins’ door, show some id and pay 10 PLN per month.

    Some time later I got access to terminal. Landed in SunOS without basically any UNIX experience (I was AmigaOS user at that time). Other users gave me some hints:

    • use “screen” as soon as you login
    • PINE is for email
    • Lynx is for web
    • Pico is your editor of choice
    • IRC is for chatting and you want Venom or Lice for it (popular ircii scripts)
    • use exit once you finish

    And I started spending time there. First weeks were tough — getting used to text interface and remembering useful commands and hints. One of most important was where to store extra files as account was 1.5 megabyte in size (with warning after crossing 1MB). Ah those /var/tmp/ or /var/news/ etc. subdirectories with everyone-can-write access :D The other was how to transfer them to floppy disks.

    Terminal knowledge

    None of terminals had a battery to keep configuration data. So often they were setup as 2400bps ones (if you powered it on and kept trashing Return key then SunOS finally appeared at such speed). One of things to learn was how to reconfigure it to 9600bps which meant quite “comfortable” work.

    Forget about using tools like Midnight Commander — it refreshed screen too often so most of time you saw only redrawing of characters.

    Also none of keys outside of alphanumeric part were usable.

    If you want more info about terminal type we used then visit HP Computer Museum page about HP262x terminal family page.

    Internet in dormitory

    When I was starting fourth year university connected one dormitory to the Internet. Surprise, surprise I lived there (it wasn’t default one for my faculty).

    During vacations I earned some good money and bought PCMCIA Ethernet card for my Amiga 1200. Oh, what change it was! No more queues to terminals. All those graphical tools and graphical web browser! And no more wondering where to go to grab files from my shell account.

    All that on 14” VGA mono monitor in 720x480 resolution.

    Commodore 128dcr can be online too

    There were two of us in the room and only one computer. So still the problem of access existed.

    One day I came out from visiting home and found out that my room mate bought Commodore 128dcr with 80 column monitor. We wired some serial cable and connected it to my Amiga. After fetching and sending some software over the wire we had 9600bps connection and 80x25 text terminal ready for use.

    Oh, those moments on IRC when we said that we use 8-bit Commodore ;D Too bad that we lack any photo from that time.

    Personal website

    I had some kind of personal website since basically forever. First version was my Lynx bookmarks with a bunch of extra text. This was quite popular type then.

    After studies my website moved between servers. Landed on some free hosting, then my friend’s server. Later on some paid space where I also had email in own domain and finally moved to self hosting in the cloud.

    The oldest copy I found in the Web Archive is from July 2003. It was on different domain that current page uses. And you can still use it to get here (there are five domains pointing here).

    I used several tools to maintain my page: php wiki, own code and over 16.5 years ago decided to give Wordpress a try. After over decade of using it moved to Pelican and it will stay that way for now.

    Future is in mobile

    I remember presentation of Nokia 9210 Communicator at some event at university. Device in your pocket with direct access to the Internet. It looked like future.

    Time passed, I met people with PalmOS devices. They used Irda for data transfer with their cellphones. Then Bluetooth with newer models. Integrated GSM modems in next ones…

    Cellphones got first versions of web browsers, mail apps… And all that moved faster and faster. We also started calling them smart phones.

    Nowadays I have multicore device in my pocket. With screen resolution higher than many people’s monitors, more memory than computers some of my friends use at work. And close to 4 terabytes of data allowance on my prepaid sim card. Something not imaginable for 20 years younger me.

  4. TensorFlow build times

    The big part of my work during last months was related to TensorFlow. We build it on Linaro CI. Resulting wheels are available on Linaro snapshots server.


    When you dig there you can find those versions:

    • 1.5.x
    • 2.4.x
    • 2.5.x
    • 2.6.x
    • 2.7.x (git HEAD)

    How to install?

    TensorFlow requires several other Python packages and some of them are not distributed as AArch64 binary wheels. For this we have Python cache repository at Linaro snapshots.

    So how to install TensorFlow (2.6.0 or 2.7.0 version):

    $ export PIP_EXTRA_INDEX_URL=https://snapshots.linaro.org/ldcg/python-cache/
    $ pip install tensorflow-aarch64

    And it will be done. Package is renamed from “tensorflow-cpu” as there is a plan of uploading them to Pypi. For older versions please check our snapshots server.

    How do we build?

    Jenkins runs shell script which then starts container, installs Ansible and then the rest of build is done using it. Playbooks, roles and shell scripts are stored in Jenkins jobs repository.

    The process is quite simple — we choose which versions to build (from 1.5, 2.4, 2.5, 2.6, git HEAD selection) and then Ansible loops over them. All dependencies’ versions are stored in variables file.

    Whole work is done inside of “manylinux2014” container to get a way of building for wide selection of Python releases. Build covers versions from 3.6 to 3.9 one (we plan to enable 3.10 when possible) in one run.

    Build times

    To compare speed of several systems I have available I ran a build on each and compared to times on Linaro CI machine.

    Some details:

    Machine name processor cores threads memory note
    Oracle cloud A1 Altra 16 16 96 VM.Standard.A1.Flex
    Linaro CI ThunderX2 2x28 56 240 SMT disabled
    SolidRun HoneyComb LX2160 16 16 32
    my work laptop i7-8665U 4 8 32 SMT enabled
    my desktop Ryzen 5 3600 6 12 32 SMT enabled

    Build time includes fetching files from network. Python packages comes from either Pypi or Linaro Python cache repository.


    Install Docker, pull manylinux2014 image, fetch script from Linaro CI job git repository, run it.

    $ docker pull quay.io/pypa/manylinux2014_aarch64
    $ wget https://git.linaro.org/ci/job/configs.git/plain/ldcg-python-manylinux-tensorflow/build.sh
    $ mkdir BUILD
    $ cd BUILD
    $ export WORKSPACE=
    $ time build26=true bash ../build.sh

    BUILD directory created as job starts with cleaning workspace (stored in WORKSPACE variable).


    Machine name build time
    Oracle cloud A1 3:15:53.250
    Linaro CI 1:56:15.994
    SolidRun HoneyComb 7:29:01.922
    my work laptop 10:01:19.044
    my desktop 3:30:34.821
    Build time (in hours)
    Build time (in hours)


    HoneyComb is a good system for development work. As long as there are other systems which will do hard work on building things.

    ThunderX2 is a workhorse. Give it something to do and it delivers. It was also very expensive (Avantek started with 13k USD for workstation).

    Oracle cloud instance used Ampere Altra cpu. Would not be surprised if it beats ThunderX2 system when more cores are used (16 cores was limit of free tier).

    I used my work laptop because it was available. Did not expected much from it. But in past benchmarks it was close to my previous desktop system.

    And with my desktop… It was quite cheap solution 2 years ago. Looks like price/performance is something where x86-64 is a king.

  5. Python package for system calls information

    Python is my favourite language. System calls table is my favourite side project. So why not merge them?

    That’s how “system-calls” Python package was born.


    Mostly because I could. And thought that maybe someone else will find it useful. Also found out that it allows me to learn how to build own Python package, how Pypi uploads work etc. stuff. And I can remind myself how packaging works as having it in Debian and Fedora would be useful experience.

    What it can do?

    Module allows to check information about Linux system calls in several ways:

    • which number system call has on architecture XYZ
    • is system call supported on architecture XYZ

    Code for it is quite simple:

    import system_calls
    syscalls = system_calls.syscalls()
    for test_call in ['openat', 'osf_uadmin', 'nosuchcall']:
            print(f"System call '{test_call}' has number: {syscalls[test_call]}")
        except system_calls.NoSuchSystemCall:
            print(f"No such system call '{test_call}' on any architecture")
        except system_calls.NotSupportedSystemCall:
            print(f"System call '{test_call}' is not supported on this "

    Above example shows usage for host architecture. But treating “system_calls.syscalls” as dictionary does not allow to ask for data of different architecture. For such use there is “get()” method:

    import system_calls
    syscalls = system_calls.syscalls()
    for test_call in ['openat', 'osf_uadmin', 'nosuchcall']:
            print(f"System call '{test_call}' on arm64 has number: "
                  f"{syscalls.get(test_call, 'arm64')}")
        except system_calls.NoSuchSystemCall:
            print(f"No such system call '{test_call}' on any architecture")
        except system_calls.NotSupportedSystemCall:
            print(f"System call '{test_call}' is not supported on this "

    You can also use “get()” method for host architecture as second argument is optional.

    You can find more examples in project’s repository.


    There is one bonus script in this project: “syscall”. Can be used to check for information about system calls for host or any supported architecture:

    $ syscall open
    On x86_64 system call number 2 is open()
    $ syscall open arm64
    On arm64 system call open() is not supported.
    $ syscall 32
    On x86_64 system call number 32 is dup()
    $ syscall 32 arm64
    On arm64 system call number 32 is flock()
    $ syscall openat mipso32
    On mipso32 system call number 4288 is openat()
    $ syscall open noa
    Architecture noa is not supported.
    $ syscall nos
    There is no such system call as nos().

    Mistakes happen

    When I wrote first version I did not thought about uploading it to Pypi and sharing with other users. And when I started packaging it for Fedora I realized that I made some serious mistake.

    Package is called “system-calls” but code was stored in “syscalls” directory. Fixed that in 5.15.2 version so it is now stored in “system_calls” one.

    5.15.3 has all tests and examples fixed to use proper names.

    If you find some other issue then please report it in project’s repository.


    Fedora 35 and above have “python3-system-calls” package available in distribution repository.

    Debian users can use my private APT repository. Not decided yet do I want to became Debian Maintainer/Developer.

  6. Programming languages

    Today is Programmer’s Day. 13 years ago I wrote a post “Am I programmer” where I defined myself more as Developer than Programmer.

    Wikipedia definition of “Programmer” says:

    A computer programmer, sometimes called a software developer, a programmer or more recently a coder (especially in more informal contexts), is a person who creates computer software. The term computer programmer can refer to a specialist in one area of computers or to a generalist who writes code for many kinds of software.

    I still do not write software used directly by users — I usually build someone else’s software. But I used to do write programs and sometimes like to do something. In some programming language and I had a chance to use many of them.


    Probably most of people born in 70s started their experience with programming using BASIC on 8bit computers. If you were out of luck you could end with Commodore 64 and it’s “PET BASIC” without any way to make use of audio/video capabilities of computer.

    I used Atari 65XE. First original Atari BASIC, then moved to Turbo BASIC XL (was faster and better). I wrote several programs in my teenager years. Enhanced some of them with short routines written in 6502 assembler.

    Once moved to Amiga and then PC I had two times when BASIC knowledge helped. During studies one of teachers knew only GW-BASIC so we had to write programs using it. Other time was some kind of BASIC on PIC 16F84 microcontroller.

    Oh, and I wrote my first 8k intro in something resembling BASIC.


    Going lower in programming stack… During Atari years I learnt a bit of MOS 6502 assembly. Once moved to Amiga had quick lesson of m68k programming. Used it to understand how “Happy New Year! 96” virus was working. Then wrote simple tool (using High Speed Pascal compiler) to kill it in all infected binaries. Some months later I got antivirus software which did it properly.

    During studies we had lot of Zilog Z80 assembly. Mostly on some old controllers from some unnamed milk company (20 keys, 8 places of 7-segment display, ADC/DAC etc.). But, as I know how to drawing block diagrams, I always had beer from other students ;D One day someone brought something weird instead of Z80 code. Turned out it was 16-bit x86 code. Took me a few minutes of reading (it was simple program).

    Then came first real MCU: PIC 16F84. First we programmed it in BASIC (it was weird), then C and finally assembly. Small amount of instructions, simple names — was fun to program.

    I never learnt x86-64 or ARM assembly. There was no need.


    Oh, LOGO… And turtle drawings. On Atari you could have 4 (or 5) turtles drawing at same time.

    I even tried to write some simple game in LOGO. But need of calling garbage collecting too often made it worthless.

    It is also first language where I wrote code for someone on piece of paper. And it worked.


    Some people would split them into two, but not me. I learnt them in a way that I wrote some of my programs in pure C, some in some form of C++ etc. Depends on needs.

    During studies some programs were first written in pure C on my Amiga. Then I used someone’s PC to add Windows UI to it (Borland C Builder mostly). My master thesis was kind of terrible C and I am not proud of it.

    My probably most complicated application is my module player. I never released it despite spending about 13 years on it (from time to time). Used it to learn Qt programming a bit.


    I learnt Turbo Pascal in a school. A bit. Never wrote anything complex in this language. Used it few times on Amiga.

    One lab during studies involved Pascal programming. I wrote code, someone reviewed it and we run it. Robot which we were supposed to control went crazy and demolished room a bit. After simple fix we repeated and all went as supposed.

    During last year I played a bit with Mad-Pascal for Atari XL/XE (cross compiler runs on Windows or Linux). Maybe there will be something from it one day.


    During my Amiga years I wanted to have some way of programming. No one from my friends had any C compiler, Pascal was not popular so I went with AmigaE.

    It was strange language. Kind of Pascal, kind of C. Allowed to mix assembly with AmigaE in one file.

    But compiler was fast and worked on 1MB machine (I had hard drive). All includes (called ‘modules’) were pre-compiled so building application was quick.

    I used it to write several applications. Released one of them in shareware model — full copy costed 5 USD (or 5 PLN for Poland). At the end of development I had about 100 users. It paid for some of my Amiga hardware.


    After studies, when I had fresh Masters in Automation and Robotics, I had to decide which way to go. Turned out that my SQL knowledge from work done during previous years can be used. Just had to learn PHP.

    After 2 weeks of learning language I was at test period in one portal. And became ‘main programmer’ there. Not because I knew PHP better then the other guy. I was good at organizing work, sorting out project into steps etc. And being GNU/Linux user I had some knowledge useful to be ‘second after admin’.

    I worked in few companies writing PHP code. For several customers. And after about 6 years I dropped it and went into Embedded Linux territory.

    Nowadays I officially lack any knowledge of PHP language.


    Another “P” language… I started using Python in 2004. Right after I found OpenEmbedded as most of it’s code was (still is) Python.

    So for 17 years I am repeating that “one day I will learn Python properly” :D

    This is my favourite programming language. Used it in OpenEmbedded, OpenStack, this blog and countless projects. Nowadays if I have to write some script then most of time it is in Python.

    Minimal version I target is still 3.6 as this is what RHEL 8 uses.


    Scripts. When not in Python then in shell. Most of time I use Bash. It works, I do not use most of it’s features.

    I can write scripts in plain POSIX shell. Not of fan but can. Some lessons learnt from years of working in embedded Linux area.


    When “P” languages are mentioned, Perl has to be present. Never learnt it. Had to maintain some scripts in Perl in past. I even managed to make some improvements to them but no idea was it in proper way. It worked.


    Reverse Polish Notation is crazy. It feels like source code written by master Yoda. I got Forth in Atari times and tried to write something. Probably never went behind ‘hello world’ ;D


    Never learnt. In past I found farm bot code for Ingress game. In Java. Took the code, expanded it, added several improvements. It worked fine. But became harder and harder to expand.

    So I rewrote it in Python 3 and forgot about Java.


    Just no. Like PHP.

    Other ones

    During years of building and porting software I had a chance to write something in several less popular languages. Erlang, Haskell, Rake, Ruby etc.

    Most of time it was something just a bit more complex than ‘hello world’ — to check does compiler/interpreter work.

  7. I moved to the new flat

    There are moments in a life when we want to change something. So I changed place of living.

    Moved out of rented flat into my own one. Still Szczecin, still suburbian part of it (I moved by about 1500 meters). Nothing fancy, plain 3 rooms but it is mine (once I pay bank’s part in next few years).

    It needs some changes as I am taller than previous owners. My list of ideas to make gets longer and longer each time I see something interesting in store of someone’s home.

    Server wardrobe

    Previous owners left several built-in wardrobes so I decided to use one for my servers. Moved my NAS, router, HoneyComb and Mustang into top shelf with all required cabling. This way none of them occupy my desk area.

    And why ‘server wardrobe’ name for it? In Polish we use ‘szafa serwerowa’ for ‘server rack’. But ‘szafa’ is also ‘wardrobe’ so that’s why :D

    New desk for my office

    In previous years I used a custom made desk. It was real monster — L-shaped with several shelves under. That allowed me to keep multiple systems running on/under desk (there were times when 16 ports in Ethernet switches were not enough).

    But it was also heavy and hard to manipulate/move. So it went to trash.

    For first days I used some table but it was not the right choice. In meantime I looked at several setups and desks to find which features to look for.

    Finally ended with buying VS series 901 desk. 180x90 cm gave me a lot of space, all cables go though dedicated gap into cable organiser under desk. And there I have Ethernet switch, laptop’s docking station (and it’s power supply), power supply for my monitor, usb hubs and all cables. No more floating cables! And all that for ~100€ for used one.

    Nicely organized desk
    Nicely organized desk

    Still need to buy some office storage unit with some drawers — it would go on left side of desk (where currently bathroom drawers are present). Looking through used office furniture again.

    Hall of fame

    On photo above you may see shelf behind my desk. I plan to organize some kind of ‘Hall of fame’ there for devices which helped with my carieer:

    • Sharp Zaurus SL-5500 (got one recently from Andrea Adami)
    • Atmel AT91SAM9263-EK developer board
    • Applied Micro Mustang

    And few other ones as I need to track where I have them first or where I can get them (anyone has spare ST NDK-15?).


    Due to some weird location of light switches I decided to speedup a bit and move most of home lights to controllable ones. To make things easier I went into system used by one of my friends: Trådfri by Ikea.

    Lights, motion sensor to get some dimmed light during night walk to toilet, remotes etc.


    It is good to have own space for living. I can alter it in any way I want. Without checking will it be useful for short people.

  8. My twenty plus years of IRC

    In 1996 I started studies at Białystok University of Technology. And one of early days I found that corridor with text terminals. Some time later I joined that crowd and started using HP-2623A term with SunOS account.

    And one of first applications crowd shown me was ircII (other were bash, screen, pine and ncftp). So I am IRC user for over 24 years now and this XKCD comics can be about me:

    2078: He announces that he's finally making the jump from screen+irssi to tmux+weechat.
    Team chat


    As wrote above I started with ircII. It was painful to use so quickly some scripts landed — Venom, Lice and some others. Tried Epic, Epic2000 and some other clients to finally end with Irssi. I have never been a fan of GUI based ones.

    There were moments when people used CTCP VERSION to check what clients other users use. In old Amiga days I usually had it set to similar one as AmIRC one but with version bumped above whatever was released. Simple trolling for all those curious people. Nowadays it simply replies with “telnet” and there was a day when I logged to IRC server and exchanged some messages using just telnet :D


    For years I was user of IRCnet. It was popular in Poland so why bother with checking other networks. But as time passed and I became more involved in FOSS projects there was a need to start using Freenode, then OFTC, Mozilla etc.

    Checked how old my accounts are as it nicely show when I started using which network.


    IRCnet was my first IRC network. Stopped using it few years ago as all channels I was on went quiet or migrated elsewhere (mostly Freenode).

    For years I was visible on Amiga channels #amisia, #amigapl where I met several friends and I am in contact with many of them still.


    The journey started on 15th May 2004. This was time when I started playing with OpenEmbedded and knew that this is a project where I will spend some of my free time (it became hobby, then job).

    It was a place where CentOS, Fedora, Linaro, OpenStack and several other projects were present.

    For me OFTC means Debian. Later also virtualization stuff as QEMU and libvirt folks sit there.

    What next?

    I saw and used several instant messaging platforms. All of them were younger than IRC. Many of them are no longer popular, several are no longer existing. IRC survived so I continue to use it.
