Welcome to cron.weekly issue #62 for Sunday January 8th, 2017.
It’s a strange and exciting week for me. We upgraded our home hardwarefrom Family 3.0 to 4.0 , the new LTS release. Because of that,I found myself awake at odd hours, skimming the web. I feel it’s a big & heavy issue, so it should keep you busy!
Take care & if you want to do me a small favour, spread word of this newsletter on your social media of choice. :wink:
News FOSDEM2017 scheduleThe schedule for one the biggest open source conferences in the world is available: mark your Februari 4th and 5th and try to be around Brussels for this one-of-a-kind conference. I know I’ll try to be there, if my hardware upgrade at home permits it.
Database Engine RankingThis project tries to build a “hierarchy” of database engines, based on its popularity. Pretty interesting to see the results, quite a few proprietary database engines are at the top, but open source dominates the list.
Moving on from net-toolsThe net-tools package, which includes binaries like ifconfig, arp, netstat, … has been deprecated since a few years. Soon, it will no longer be shipped with your favourite linux distro. It’s time to move on and learn about its replacer, iproute2 , which features the “ ip ” command. (think: ip route, ip address, …)
Open-Sourcing Our Incident Response DocumentationThis is a really interesting approach where PagerDuty releases their documentation on how to handle incidents, on-call and alerting principles. Lots of things to learn here!
How fast are Unix domain sockets?2 proof of concepts are explored here: IP vs UNIX sockets. I expected a difference in performance, but this post shows just how much of a difference it is. Worth a read, if only to scroll to the conclusion at the bottom!
OpenPGP really worksThis post highlights some areas where PGP shines and is actively used, even in cases where you might not know it’s being used.
DistroWatch:Some of the smallest Linux distributionsA look at 5 of the smallest Linux distributions out there, if you’re looking for inspiration for a new base Docker image or lightweight VM.
php 5.6 is End Of LifeWell, sort of. It won’t get any more bugfixes, but can count on 2 more years of security fixes. That essentially leaves PHP 7.0 and 7.1 as the onlysupported versions of PHP out there. Time to upgrade!

Irssi 1.0This popular IRC client has reached a 1.0 milestone.
Sed 4.3I don’t usually get very excited about sed releases, but there’s an interesting footnote here: “ sed’s regular expression matching is now typically 10x faster “. I’ve said many things about sed before, but I never called it slow. And now it’s 10x faster.
ntfyntfy brings notification to your shell. It can automatically provide desktop notifications when long running commands finish or it can send push notifications to your phone when a specific command finishes.
Grumpy: Go running python!Grumpytranslates Python code into Go programs, and those transpiled programs run seamlessly within the Go runtime. It removes the Global Interpreter Lock (GIL) from Python and provides a way to scale beyond the limits of “normal” Python. This project reminds me of Facebook’s HipHop , that translated PHP to high-performant C++. That project later became the HHVM runtime .
LeoFSLeoFS is an unstructured object/data storage for the Web and a highly available, distributed, eventually consistent storage system.
SeaweedFSSeaweedFS is a simple and highly scalable distributed file system. There are two objectives: to store billions of files & to serve the files fast! Instead of supporting full POSIX file system semantics, SeaweedFS choose to implement only a key~file mapping. Similar to the word “NoSQL”, you can call it as “NoFS”.
DropwatchThis toolimproves your ability to detect and understand packets that get dropped within the network stack on your server.
CheramiThe team at Uber has released Cherami:a distributed, scalable, durable, and highly available message queue system to transport asynchronous tasks.
SecGenSecGen is a Ruby application that uses virtualization software to create vulnerable virtual machines so students can learn security penetration testing techniques.Boxes like Metasploitable3 are always the same, this project uses Vagrant, Puppet, and Ruby to quickly create randomly vulnerable virtual machines that can be used for learning or CTF events.
