fcambus··on Playing with DJGPP and GCC 10 on DOS
The character and color cycling effect program mentioned at the end of the article is available here: https://www.cambus.net/character-and-color-cycling-effect-in...
fcambus··on GNU poke: The extensible editor for structured binary data
It's a bit overkill for only building Poke, but you can use Pkgsrc [1] to do so on macOS:

Bootstrap Pkgsrc:

git clone https://github.com/NetBSD/pkgsrc.git

cd pkgsrc/bootstrap

./bootstrap --unprivileged

And then build and install Poke:

cd ~/pkgsrc/editors/poke

bmake install package clean clean-depends

[1] https://pkgsrc.org

fcambus··on Lesser Known Coding Fonts
Taking the opportunity to mention Spleen, which I've been working on for the past year: https://github.com/fcambus/spleen

It is a monospaced bitmap font available in several sizes, ranging from 5x8 up to 32x64.

fcambus··on Fuzzing Filesystems on NetBSD via AFL+KCOV [pdf]
To give a bit more context, this is part of a wider effort to fuzz the NetBSD kernel.

This other presentation from EuroBSDcon 2019 is an overview of the ongoing work: https://netbsd.org/~kamil/eurobsdcon2019_fuzzing/presentatio...

fcambus··on Nginx C function
For a more mature implementation of this concept, I would highly recommend having a look at Kore: https://kore.io

It has a sane architecture, and is fully privilege separated by default, with private keys isolated in a separate process. I've been using it lately to write REST APIs in C, and the experience has been awesome, it has great APIs to parse requests and easily construct responses.

fcambus··on Theo de Raadt – Privilege Separation and Pledge [video, ~15min]
Slides : http://www.openbsd.org/papers/dot2016.pdf
fcambus··on Weather in your terminal, with ANSI colors and Unicode symbols
For info, it's also packaged in OpenBSD, NetBSD and FreeBSD.

There is also an Homebrew formula for OS X users.

fcambus··on Implementation of Xen PVHVM Drivers in OpenBSD [pdf]
Full paper is available here : http://www.openbsd.org/papers/asiabsdcon2016-xen-paper.pdf
fcambus··on A shell command to create JSON: jo
I pointed your comment to the author, and he updated the examples to mention this possibility :

fcambus··on Chuck Forsberg has died – author of Zmodem
File : zmodem general Version : 1.02

(C) Mattheij Computer Service 1994

I recently stumbled upon this in the header of a ZMODEM implementation in C, thinking you were likely the author. Now I have no doubts that you are ;)

Any stories to share regarding this implementation and how it came to be?

fcambus··on OpenBSD developers: Landry Breuil
I have been reading all the interviews so far, it's been a great serie!

Wondering how many more interviews are planned? Hopefully a lot more, that's super informative and motivating.

fcambus··on Dillo: A Tiny Graphical Web Browser
Haven't checked 2015Q3 yet, still using 2015Q2 where it's available. It might be broken or failed to build in 2015Q3 then :(
fcambus··on Dillo: A Tiny Graphical Web Browser
Dillo is part of Pkgsrc, and can easily be installed on OS X.

Bootstrap this : https://pkgsrc.joyent.com/install-on-osx/

And then it's as easy as : pkgin install dillo

fcambus··on NetBSD-7.0 developer interview: Leonardo Taccari
Nice to see this appearing on HN, this is shaping up to be a great interview serie!

For info, the first one was with Jeff Rizzo : http://beastie.pl/deweloperzy-netbsd-7-0-jeff-rizzo/

fcambus··on Cost of Privacy
It seems I cannot post a comment on your blog without being registered on Google+, so answering here instead.

I enjoy reading your articles on OpenBSD and would indeed appreciate it if you would move the content to your own server, as the blogspot cookies notification banner is pretty irritating :)

fcambus··on Logswan – Fast Web log analyzer using probabilistic data structures
Thanks for reporting this.

Indeed, there was no site configured on logswan.org when this was posted to HN. I made the required changes but due to the nature of DNS, it'll still return NXDOMAIN for some users until caches are cleared.

fcambus··on JavaScript GameBoy Advance Emulator
Nice, I was hoping someone would find something missing :) Thanks for mentioning this, just updated the list.

PS: Great work on jor1k!

fcambus··on JavaScript GameBoy Advance Emulator

fcambus··on Something about DNS
Indeed, check here : http://calle.dybedahl.se/dns.html
fcambus··on Luajit IO framework
Announcement with more details can be found here : http://permalink.gmane.org/gmane.comp.lang.lua.general/11626...
fcambus··on LibreSSL 2.1.5 released
From the release announcement :

This or earlier LibreSSL releases may also address issues that are to be revealed by The OpenSSL Project Team on the 19th of March, 2015.

fcambus··on Converting OpenBSD to PIE [pdf]
Slides are available here : http://www.openbsd.org/papers/asiabsdcon2015-pie-slides.pdf

Slides are available here : http://www.openbsd.org/papers/httpd-slides-asiabsdcon2015.pd...
fcambus··on Show HN: Discover your ranking on GitHub
Wondering how you deal with city names in languages other that English? Is that taken into account?

For example, it seems that for Kraków (Poland) you have both Kraków and Cracow.

PS : Great project!

fcambus··on Show HN: Artpacks.org – Archive of the ANSI and ASCII art scene (1990 to present)

fcambus··on Bootstra.386 – A Bootstrap theme from the 1980s
Indeed, PTT has a lot of beautiful screens, and for those of us used to the CP437 character set, it looks quite exotic!

For those interested, here are some captures of some of the menus (there is a lot more posted in conferences) :
