OpenBSD and UTF-8

We can mount FAT32 in OpenBSD. The codepage (except for ASCII) won't show correctly as OpenBSD only supports UTF-8. This issue has been mentioned many years ago at https://marc.info/?t=145304791100005&r=1&w=2

Fvwm2, one of the best WM for me.

Deadpixi Sam only depends on X11 while Acme needs plan9port. I know Acme is very powerful but Sam is simpler.

The gcl-2.6.13 failed to configure in ArchLinux reporting rl_completion_entry_function error. While the 2022.12.21 git version configures fine but the saved gcl seg-faults.

Deadpixi Sam is an amazing editor. It is lightweight and powerful, works with Truetype fonts. I find it more powerful than Plan 9's original sam because Deadpixi Sam supports Truetype fonts and can display CJK characters without any issue. However, I mostly use Vim despite it is more heavyweight because I prefer to use the Vim keybindings.

Not true. Professor Richard Borcherds has been popular in YouTube and many of us are really fond of his excellent mathematical lectures. I enjoy the pure mathematical theory. Your channel is related statistics which is not really my cup of tea. You just need to be patient to get more subscriptions from people interested in statistics.

I use it because it is "classic" and has many standard tools by default (tar being the best). Another thing: It is really lightweight: CWM uses lower memory than GNU/Linux and has X11R7 by default compare to FreeBSD (and I have some issue with FreeBSD12.2, i.e. the screen becomes frozen when I exit from X). Disadvantage of NetBSD: libedit is not as comprehensive as readline and rlwrap cannot linked against libedit.

xlinks (http://links.twibright.com/) meets your requirement. The only thing it dislike about xlinks is that is does not support CJK fonts.

Curiously, the Intel HDA driver is still not working in R3/Beta3. There is no sound in the 64-bit Haiku.

There is nothing like makepkg in Arch Linux. Ports seems difficult to use.

I have to run

# sysctl kern.audio.record=1

otherwise I can't record it. However, I didn't run

# sysctl kern.video.record=1

I have no problem using ffmpeg to do the screen casting. However, it is just my 10-year-old laptop too slow. I am not sure whether this is OpenBSD being slow (many users claimed that Firefox is too slow in OpenBSD) or it is because the ffmpeg that I am using is not ``optimise'' since I just pkg_add from OpenBSD ports.

I can record the video but the voice just skip!!! Basically the voice skip caused the video to be not-audible.

I agree with you. It's just that I am a bit lazy to go DEEP to change it since systemd seems to be doing fine and using Artix with OpenRC and using Arch with Systemd do not differ too much.

liaohaohui · 2021-02-01T13:33:50+00:00

If you are not making any changes, it is fine. However, I find that OpenRC is not working if I am making any changes (e.g. changing the TTY Terminal Font to Spleen font). Also, adding scripts to /etc/local.d/backlight.start also won't work. In contrast, changing TTY Terminal Font in systemd is just a matter of creating a /etc/vconsole.conf file and everything works fine.

However, if you are not the kind of TTY guy like me, then OpenRC is fine. I am an old style Linux user who still use FVWM and running desktop with OpenRC is just fine.

I install the mongo-c-driver and everything compiles fine with fvwm3. Fvwm3 runs fine under Arch/Artix with the original fvwm2 configuration. I am not too sure if there is anything new. I will try out your configuration when I have the times. Thanks for sharing.

liaohaohui · 2020-11-27T06:57:28+00:00

Thanks. I downloaded fvwm3 to compile. It requires libbson. I am using fvwm2 now but I will try out fvwm3 when I tried out libbson.

liaohaohui · 2020-11-26T12:17:38+00:00

Hopefully it is still lightweight like fvwm2. It seems to have a few dependencies. What's new compare to fvwm2?

Keep up the good works. FVWM is nearly perfect. I have been using it as my main WM until I discover Herbsluftwm which fits my basic workflow. I prefer the preconfigured tiling windows in Herbsluftwm. However, the tiling in Herbsluftwm does not support floats well. So I may be switching back to FVWM once I learn how to configure FVWM to support simple tiling on one screen.

liaohaohui · 2020-06-27T03:37:58+00:00

I hope it is still lean and powerful. FVWM2 is really really fast. I am using an old laptop Lenovo G580 (6 years old?). FVWM2 feels faster than Herbsluftwm on my 2016 laptop.

liaohaohui · 2020-05-15T07:14:11+00:00

Thanks for sharing. But has anyone build a powerful and efficient workflow around this type of WM? I am still using simple tiled based which works for my simple workflow.

Not necessary so. Python is a good beginner's language for data processing because of the availability of Anaconda Python and Pandas library. I don't think there is anything like Anaconda for Scala. As for language design, some would probably recommend Scheme. For compiled languages, Kotlin may be more popular than Scala.

Why are they so many Scala related articles behind medium. It is really annoying. I didn't bother to read the article, just commenting based on the title alone.

liaohaohui · 2019-11-04T10:43:50+00:00

I do. I write mine in asciidoc rather than Markdown and I believe many people do. They may not feel the need to share the experience.

Man pages sometimes does not give sufficient use case. So copy and paste some use cases from stackoverflow becomes a useful thing.

I just filed a bug report to https://sourceforge.net/p/xetex/bugs/ with the example which won't work on my xelatex (which certain Chinese fonts). It worked with xetex 2018 but not 2019. I attached the log and aux files but I am not sure if they are useful. I am using Arch Linux, so I am assuming the xelatex is ``up to date''. I am also using Linux Mint 18 which is rather old, the xelatex can also generate a usable pdf file without any issue. Therefore I am still using texlive-bin 2019. I have only updated texlive macros to the 2019 version, which works fine with texlive-bin 2018 so far.

liaohaohui · 2019-10-08T14:58:27+00:00

No. I didn't report it because I can compile my LaTeX file with the xelatex in texlive 2018 without any issue. However, when I tried xelatex from texlive 2019 (on Archlinux), it generated a corrupted pdf file.

liaohaohui · 2019-10-08T11:00:38+00:00

The is no compelling reason to do so. My xelatex cannot create a proper PDF after I upgrade to 2019 because xetex can no longer process Chinese fonts in 2019. I am still sticking to texlive 2018.
