Last day

Published on April 3, 2015 by Filip Van Tittelboom

Today is my last day as a Skyscraper! I will be joining a startup that is in the process of developing an Internet of Things (IoT) platform. I’d like to thank each and every one of my colleagues and customers (past and present) for helping to create such a satisfying and pleasant work environment over […]

GLIBC ‘Ghost’ vulnerability

Published on January 28, 2015 by Filip Van Tittelboom

Yesterday evening, there was a lot of talk on the ol’ interwebz about the latest ‘Internet Killer’ bug dubbed ‘Ghost’. It’s a GLIBC vulnerability (CVE-2015-0235) affecting almost every Linux distribution. A remote attacker able to call the affected functions could exploit the flaw to execute arbitrary code with the permissions of the user running the […]

End-Of-Life Ubuntu 10.04 LTS

Published on January 6, 2015 by Filip Van Tittelboom

This is just a friendly reminder that support for the linux distribution Ubuntu 10.04 LTS ‘Lucid Lynx’ will stop as of April this year. Those instances won’t receive Canonicals 5 year ‘Long-term support’ (LTS) anymore. This means no more security patches and updates to the ‘Ubuntu stack’. It’s important to remember that future vulnerabilities would […]

Working at Skyscrapers – a small Q&A

Published on November 13, 2014 by Filip Van Tittelboom

We get a lot of similar questions from applicants, so I decided to write a small Q&A from the point of view of an employee. Not that we call ourselves employees. We call ourselves team-members. Q: Can you describe a typical day? A: You’ll work closely with the developers of our partners; designing, deploying, managing, […]

SHA-2 HTTPS certificates

Published on October 30, 2014 by Filip Van Tittelboom

Last month Google, Firefox and Microsoft announced they will be retiring support of SHA-1, the cryptographic hash algorithm used in HTTPS SSL certificates. They calculated that it became too affordable to decrypt SHA-1 certificates and are upping the security of their applications. Future browser versions (next year) will show an error or warning message if […]

The Remote Working Experiment

Published on January 9, 2014 by Filip Van Tittelboom

A couple of weeks ago I had to undergo some minor surgery. No worries, nothing serious! For three weeks I wasn’t allowed to ride my bike to work anymore. Our main office is a coworking space in the northern part of the city. To get there on time by car is nearly impossible. It was […]

So we emptied our last rack in Brussels today. From now on all of our internal and customer infrastructure runs 100% in the cloud.

Back in the Day

Published on September 2, 2013 by Filip Van Tittelboom

When doing the things I do now, it’s funny to reminisce about my first job as a system administrator. I worked for a small company that managed servers and networks for small businesses. They also did colocation. A typical scenario would be to get a call from a customer: “We’d like to move our web […]

Htaccess Files: The Silent (Performance) Killer

Published on April 3, 2013 by Filip Van Tittelboom

Htaccess files are convenient. They let you change settings without restarting Apache. It gives non-root users the ability to configure certain server settings. You don’t have to bother your friendly system administrator for a small tune. Best of all: changes are effective immediately. A lot of mainstream CMS and frameworks come with pre-packaged htaccess files […]

Last week, we moved our IPv6 service from alpha to beta. IPv4 addresses are running out fast, so we can’t stay behind on our IPv6 development. Converting the iLibris nameservers was the most important part. These allow us to run your website on both IPv4 and IPv6. After a testing period, it was time to […]

Monitoring and beer

Published on December 2, 2011 by Filip Van Tittelboom

Our partners expect their web applications to be available 24/7. So one of the less visible services we provide is ‘monitoring’. If a problem should arise, we want to be notified. If that problem occurs after business hours, the operator on call should be notified. This article will try to explain how we implement these […]
