Server Hardening
Introduction Security of a system is often overlooked or not considered important enough. Some might think not about the possible consequences, which might result in a hacked or compromised server. Maybe sensitive data gets stolen or encrypted with major consequences.
A collection of tools, techniques and best pratices can help to reduce such vulnerabilities. This process is called system hardening.
We have seen quote a lot of hacks and data breaches over the past years across different big companies, including but not limited to: PayPal, LastPast, T-Mobile, MailChimp, Netflix, Dropbox, OpenSea, Twitter…

GitLab: Pull from remote repo
GitLab is an awesome product. I’m using GitLab Community Edition (FOSS) at home on a daily basis.
However, I needed a specific feature in GitLab called Pull from a remote repository which is officially a premium feature only. Too bad this feature is not free, but I have a solution.
This sync feature allows you to keep for example your forked repository in sync with a remote upstream repository.

New server: Install & configuration of services (Part III)
Welcome back, this will be the 3rd part of new server series. In the previous parts I assembled the server and prepared the machine with Ubuntu Server. I configured the basics things like; networking, RAID setup, E-Mail and more. In case you missed that: read Part I and Part II.
Today, we will finish the job with installing and configuring all the services we love so much. Again, I included a Table of Contents for convenience reasons, since it quite a long article.

GPT-3 – We are doomed
I would like to talk about artificial intelligence (AI), GPT-3 to be specific. Has been a while since I posted an article, but I noticed an urge to write about GPT-3 🙂. Without further ado, let’s get into what GPT-3 is. And why this is such an important topic to discuss.

Air quality meter
Current co-location Lately, I moved buildings for my work towards a building which is very close by Eindhoven Airport. Only 430 meters to be precise.
The air-planes and kerosene smell triggered me about the health risks, and air quality inside the building as well as at home. The fact is that we have more and more cars/trucks within the residential areas (too bad still running on fossil fuel). Meaning our health is at risk, and apparently nobody cares.

Upgrading GitLab server
I got a running GitLab server on my Debian Jessie server. GitLab Community Edition is an open-source git repository manager, but also supports code reviews, wiki’s, issue tracking and much more! GitLab is very similar to Github in a way, however you have full control of the server. You are running your own git server.
Normally Github will do all the system administration, upgrades and such for you. They make sure your code is safe and saved no matter what.

Git hooks
Recently I found the benefits of using git hooks. I want you explain in this article more about git hooks. What are git hooks in the first place? What for hooks are there? (no I’m not talking about a fish hook). And how to use git hooks in combination in my favorite open-source git server: GitLab.
Git hooks A git hook is a way to fire off your own custom scripts (perl, python or bash it doesn’t really matter).

Why should you upgrade to PHP7?
Developers who running PHP-enabled websites such as WordPress, Drupal, Joomla, Magento or even PHP frameworks like Laravel and Symfony should know about the new major PHP version.

And uhm… what about PHP version 6?
Usage About about 98% of the websites are still using PHP version 5.

Herstel bricked Router
Ik had per ongelijk de Netgear router gebrickt, of in ieder geval de router startte niet meer goed op. Als een apparaat (router, smartphone, game console) bricked is, betekend dat hij niet goed geconfigureerd is, corrupte firmware of een hardware problemen heeft.
Waardoor het betreffende apparaat niet meer goed kan functioneren. En daardoor zou de router enkel nog bruikbaar zijn als jawel een &“brick” (=baksteen). Oopsy!

Debian 8 Jessie Server handleiding
Niet lang geleden heb ik mijn server opnieuw opgezet. Ik maak gebruik van Debian 8 (Jessie) als Linux distributie, en heb veel verschillende services geïnstalleerd en geconfigureerd (waaronder een mail server, webmail, cloud storage en git). Gelukkig hield ik alles netjes bij in een logboek. Ik zou graag mijn stappen willen delen, zodat iedereen een eigen server kan opzetten.
Ik ga ervan uit dat je beschikt over enige basis kennis van GNU/Linux (Debian). Ook al beschik je niet tot nauwelijks over deze kennis, zou het toch mogelijk moeten zijn om deze handleiding stap voor stap te volgen.

Databases 2.0 – Cassandra
Ik ben bezig met het opzetten van een eigen weerstation. Tijdens het opzetten kwam ik er achter, dat je een grote hoeveelheden data wilt opslaan (temperatuur, luchtvochtigheid, wind-snelheid, en meer…) en dat elke 10 seconden opnieuw. In dit artikel ga ik Cassandra gebruiken en leg ik uit waarom het efficiënter is vergeleken met MySQL of andere relationele databases.

Newsgroup Client
Usenet Newsgroups is a way to communicate between people on the Internet. Newsgroup is a discussion group and despite the name not for news. Usenet Newsgroup were the most used Internet service when the World Wide Web (WWW) didn’t exist yet. Newsgroup uses Network News Transfer Protocol (NNTP) for distributing the posts.

SSH tunneling: interne/externe poort doorsturing
SSH (Secure-shell) wordt gebruikt om remote in te loggen in een server of computer. Maar wist je dat je nog veel meer met SSH kunt doen? Naast remote inloggen, bied SSH ook ondersteuning voor het doorsturen van TCP poorten (tunnel), X11 verbindingen om je beeld door te sturen en tot slot bestandsoverdracht (wat via SFTP of SCP gaat).
We houden het in dit artikel bij het doorsturen van poorten, ook wel SSH tunneling genoemd.
Wat is SSH tunneling? En wat kun je er allemaal mee doen?

Ubuntu commando's & locaties
Ik kreeg onlangs de vraag of ik enkele handige commando’s wist voor op Ubuntu. Voor de mensen die niet weten wat Ubuntu is, dat is een besturingssysteem net als Windows of Mac OS X, maar deze is gebaseerd op GNU/Linux genaamd “Ubuntu Linux” Deze zogenaamde distributie is gratis te downloaden en te gebruiken. Lees dit artikel verder voor alle handige commando’s en locaties voor Ubuntu.
Goed alternatief voor Ubuntu is Linux Mint, ook tevens gratis te gebruiken.
