PrivateBin 1.4.0 released - Hardening the attachment preview, Google Cloud Storage and Oracle database support & adding new translations


My team at LzLabs GmbH in Wallisellen, Switzerland, is looking for a 4th DevOps Engineer. You'd be working primarily with a CloudBees (Jenkins) cluster of around 90 blades for build & testing, for several software stacks that targets RHEL, but hopefully soon™ also other platforms. And of course there are also a lot of build and deployment related projects to be spice things up on the side, like maintaining and developing a test statistics database, code coverage reporting, change log and other automation projects, all in a mostly ansible-ized environment. The companies main language is English, living in or moving to the vicinity of Zürich would certainly be advantageous.

Next week a new hire starts in our team. To help them find their way in our environment, we created this map. Let's hope it wont scare them away. :-D


Yeah, das Friendica Update war wieder einmal ein voller Erfolg! Ich freue mich immer darauf nach dem Update die Netzwerkstatistiken zu durchstöbern und zu sehen wie das Fediverse wächst und gedeiht. Aktuell sehe ich da bei mir:
Momentan kennt dieser Knoten 2065 Knoten mit insgesamt 1238363700 registrierten Nutzern, die die folgenden Plattformen verwenden:
- Friendica (234/14306)
- BirdsiteLIVE (3/9295)
- Diaspora (104/745029)
- [...]
- Lemmy (4/15876)
- Mastodon (1195/2801105)
- Misskey (33/1234575069)
Hm, die Misskey stats bedürfen wohl noch etwas der Interpretation... 🤔

Oh, wow: Nachdem ich von den beiden Druckwellen des Vulkanausbruches in der Nähe von Tonga hörte, habe ich in den Messungen von meiner kleinen Wetterstation nachgeguckt und die sind dort klar zu erkennen!



Als ich 1997 meine erste Reise in die USA machte, hatte ich einen Psion Siena dabei und darauf Tagebuch geführt. Leider konnte ich mir damals das Datenkabel nicht leisten und es irgendwann verpasst die leeren Batterien zu tauschen und die Dokumente gingen so verloren.

Vor einigen Wochen habe ich mir aus Neugier dessen grossen Bruder angeschafft, den Psion Series 3a. Und diesmal auch ein serielles Kabel dazu, damit ich Programme hoch- und Daten davon runter laden kann. Hab mal ein paar Notizen dazu gemacht:

Not entirely serious question: Why does the Gnome Terminal icon represent an IBM PC DOS prompt instead of UNIX shell prompt? Is that what folks think of first, when they think of a command prompt?

Good morning, currently reading a book called:

10 PRINT CHR$(205.5+RND(1)); : GOTO 10

The book's title and subject is the one liner that produces a maze on the Commodore 64 BASIC V2. In one of the chapters the books authors consider ports to other 8 bit systems, as well as modern scripting languages, using unicode characters. Here is their port to perl:

perl -e 'binmode STDOUT,"utf8";{print chr(9585.5+rand);redo}'

Got me inspired, here are my attempts for python (the second one cheats a bit, as it uses POSIX shell to format the script):

python3 -c 'import random;exec("while True:\n\tprint(chr(int(9585.5+random.random())),end=\"\");")'
printf "import random\nwhile True:\n\tprint(chr(int(9585.5+random.random())),end='')" | python3 -

and php (still no native unicode support, so have to build the 3 bytes for the utf-8 symbol one by one):

php -r 'while(1){echo chr(226),chr(149),chr(177.5+rand(0,1));}'

bash -c 'while true;do printf %b "\U$(printf %08x $((9585 + $RANDOM % 2)))";done'


Shell parsing is hard.

Yes, shell parsing is non-obvious - it does help enormously to understand that the shell takes what you type on the command line after you hit enter, parses it, replacing variables, expanding globs (wildcards) and other language constructs in the process and only then issues a system call, passing the resulting argv structure to the kernel for execution.

Exhibit A (source of the above quote): How the local shell ssh and the remote shell interact, in unexpected ways

Exhibit B: skarnet's introduction to the execline language design and grammar goes into further details of the argv structure

Exhibit C: How to use execlineb for nginx to wait for up to 10s on the startup of php-fpm, avoiding involvment of a shell process



PrivateBin 1.3.5 released - Fixing several smaller issues, adding new translations

Some context: Got this picture presented this morning in my social media timeline after experiencing my first internet outage at home in over 5 years (aka since I moved into my current flat). Perfect picture for this moment. :-D

Didn't remember how awkward it is to get disconnected from the net. Now having to use my backup SIM card in the notebook for internet over GPRS/WWAN - to rant on social media about not having internet. ;-) #firstworldproblems


Many folks don't know that the Unicode standard is actually much older then they think. Here's the spec as of 1889 ;-)

Started looking into gemini space. Love how it feels - it's like the web ca. mid-90s. UI is back under your control and you can focus on reading the content instead of getting the site to work (because either you have issues with noscript turned on and sites requiring JS to display text or you have it disabled and have to click through modal windows informing you of cookie settings, sign up for that newsletter, etc. to get to the content).

I'm using Castor and wanted to merry it to my Gnome desktop, so clicking links in Firefox/Chromium opens them in Castor. Oh, and I got a gopher client for free with it as well. Was bummed when Firefox dropped gopher support. Here's how to register the gemini protocol in Gnome (and build castor):

While grep and sed are commoly used, awk fills a valuable niche when processing structured text, avoiding multiple pipes or more complicated regex extractions. Here is a handy flowchart to pick the ideal tool for your text processing task:


A plaintext chart and a simple example making use of several awk features can be found here:

Which UNIX tool to use for text processing?


Small tools to use as (non-sharable) sketchpads - if you need a quick spreadsheet calculation or text editor and are to lazy to open a terminal. Good example of #minimalism and very #privacy minded.


Maybe a concept we could evaluate for use in our fediverse software as well:
This forms a relative reputation system. As uncomfortable as it may be, one man’s terrorist is another man’s freedom fighter, and different jurisdictions have different laws - and it’s not up to the Foundation to play God and adjudicate. Each user/moderator/admin should be free to make up their own mind and decide which reputation feeds to align themselves with.

Liebe Freunde des gepflegten Alteisens! Kommendes Wochenende ist Vintage Computing Festival Berlin 2020, und ihr könnt das alle besuchen, ohne auch nur einen einzigen Fuß vor die Tür zu tun. Ich bin dieses Jahr leider nur passiv dabei. Schade finde ich insbesondere, dass dieses Jahr die Fotografiererei auf der Strecke bleiben wird: # # # #

Falls Du einen hast und das Display noch funktioniert - Quietscht Deiner auch so, beim Aufklappen? Bei meinem habe ich deswegen versucht das Scharnier etwas zu ölen, aber es ist immer noch recht laut. Auch habe ich den Bolzen wie im PoFo-Wiki beschrieben bearbeitet, um hoffentlich die Lebensdauer des Bildschirmkabels etwas zu verlängern.

Für mein erstes Projekt in Rust suche ich noch eine geeignete freie Lizenz. Da es sich um einen Dienst handelt, welcher hauptsächlich als Webseite genutzt wird, hatte ich an die AGPL gedacht. Mir fiel aber auf, das die meisten darin verwendeten Bibliotheken MIT und Apache lizenziert sind, was ich eher von Software kenne, die auch kommerziell genutzt werden soll. Für Empfehlungen die für oder gegen eine der genannten Lizenzen sprechen bin ich dankbar. #FollowerPower
