A classic bug for a leap day: At work, colleagues discovered and fixed a bug in a lesser used tool that only occurs on February 29th. It did trip up the tests, so no one got to merge until it got identified and resolved.

The source file in question hadn't been touched in over 4 years. Last leap year, the 29th was on a Saturday, so likely no one noticed.

What was annoying is that the logic had been clearly written with the intent of handling leap years. A leap year check condition was present, validated only on a February > 28th, but had to get inverted.

You may wonder why we wouldn't have used the languages' standard library date functions to validate the date - unfortunately the language in question doesn't have such a sophisticated standard library (language omitted to protect the innocent).

Wirth's law, named after him, is an adage which states that software gets slower more rapidly than hardware gets faster.

Congratulations to Sergio Benitez on releasing rocket.rs 0.5.0! Thank you for this great framework. 👏

I got to follow rocket's journey to async and stable #rust with the PrivateBin directory service. Coming from Python flask apps, it is really easy to pick up and get going with your webservice, offering static & templated content, easy to create web forms and JSON APIs.

Thanks to rust's strict type system I could focus on the logic and didn't have to waste time double checking and casting data received by clients. If my API accepts an integer in a certain parameter, Rocket will ensure I only receive valid requests in my logic.

Microsoft, quietly, has published a guide on how to download and install Linux.

No... Seriously... It is not a joke...

https://learn.microsoft.com/en-us/linux/install

The article was published September 29, 2023 (9 days ago).

The guide provides every option available, too. Starting with using their Windows Subsystem for Linux (WSL), to using a Virtual Machine, and even on "Bare Metal" alongside Windows.

That's right, Microsoft now tells you how to dual-boot Linux. 🤯

I like CSS-animations, clocks and dials for making metrics easier to digest (we are quicker at detecting angular changes than reading and parsing digits). So I'm in awe with this creative use of a watch-dial to visualize a 32-bit hexadecimal number:

what’s a good use-case for PyCurl, etc? I use curl on the command like daily, but not sure what I would do with it in a program. I’m sure that I’m missing something.
in reply to Ben Hayes

@benhayes if you write a program that needs Internet transfers for example...
in reply to daniel:// stenberg://

i think most people would just use requests module. maybe i'll try pycurl in future.
in reply to Ben Hayes

@benhayes everyone should use the tool they deem necessary to solve their problem
in reply to Ben Hayes

While python 3 now has decent native support for HTTP(S) with it's urllib module (which does cover 99+% of my use cases), PyCurl supports "FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS, FILE, IMAP, SMTP, POP3 and RTSP. libcurl supports SSL certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form based upload, proxies, cookies, user+password authentication (Basic, Digest, NTLM, Negotiate, Kerberos4), file transfer resume, http proxy tunneling and more!" -- http://pycurl.io/

So it can solves those edge cases. It may also be useful if you hit performance or memory usage issues in your python based search spider or similar massively parallel connection applications.

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.

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));}'
in reply to elrido

bash:

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
