Personal,linux,open source 22 July 2010 | 71 Comments

Ok, so I did it. I went from my truly lovely iPhone (3G) to a Android phone. My choice is the Samsung Galaxy i9000 (some call it GT-9000). So, how is the experience so far? Actually, I can say nothing else then just good thing about it. The Android OS feels just like…. natural. You [...]

On my way to Linux – Part One

linux,open source 20 July 2010 | 17 Comments

Right, so here is the scope. I’ve been a MacOS X user for many years, not that I have been a fanatic one but I simply used what works best for me. In any case, I own 3 Mac Mini’s and mostly got a new MacBook Pro every year. I also converted quite a lot [...]

Getting SUN Java 6 JRE installed on Ubuntu 10

linux,open source 16 July 2010 | 16 Comments

So far, installing SUN Java versions have always been a bit of a “pain” under Linux. Well, as I said, when you need SUN’s Java version that is. Most of the time you need to go to their intuitive (fun intended) download page and think very hard which version to download. Ubuntu has made this [...]

Nginx error with Tomcat – upstream sent too big header while reading response header from upstream

Development,linux,open source 2 February 2010 | 12 Comments

Nginx is our favorite web server currently as it is fast, lean and easy to configure. Performance is just outstanding and if you haven’t take a look at it. One thing that I noticed while we deployed Nginx with Tomcat is that their default size for the buffers are very low. Don’t know why a [...]

SugarCRM: Inbound eMail

linux,open source 17 January 2010 | 9 Comments

SugarCRM is a good open source CRM, but the overwhelming functions and navigation makes it “sometimes” hard to really get to the one thing you want to do. In any case, it does the job well. Apart from that, I just came upon this error message within SugarCRM: Warnings: Inbound Email cannot function without the IMAP [...]

Nginx, Apache, SSL and signed by an unknown certifying authority

linux,open source 17 January 2010 | 52 Comments

We just moved a whole bunch of servers to a new hosting center and moved from CentOS to Ubuntu (server) and Apache to Nginx (more on this in a later blog post). While we migrated mostly everything without problems we were confronted with the problem that our SSL certificate gave us an error message of [...]

Syntactically invalid HELO argument(s)

linux,open source 14 January 2010 | 27 Comments

Just been going trough a lot of reconfiguration lately and today finished configuring a new server. While testing the mail function we saw in the mail logs the following lines: javax.mail.MessagingException – 501 Syntactically invalid HELO argument(s) First we thought, it is the application server or sendmail/exim not being properly configured. But as we soon [...]

Get the latest libraries for CentOS

linux,open source 31 December 2009 | 11 Comments

CentOS, being a “legal copy” of RedHat, as good as it is, comes with some really outdated libraries. This has caused many, including myself, to find way how to bring latest code releases into CentOS. Be it by alternatives repros or compiling the packages. Now, I don’t know how I could overlook it, but I [...]

Solutions for Oracle ORA-28002 and ORA-27101

Development,linux,open source 11 December 2009 | 18 Comments

Running an Oracle database is great, because it is stable and just runs, but sometimes you are hit with unexpected errors when you restart your machine. Thought, I know Oracle quite well, I’m always surprised at some things. Here are two errors (and solution) I was just confronted with: ORA-27101: shared memory realm does not [...]

ImageMagick and Ghostscript playing nice with web applications

Development,linux,open source 20 November 2009 | 24 Comments

I had to spent way too much time the last time to set up ImageMagick and Ghostscript together that I simply jump right in so you don’t have to waste time on this, like I did. Creating thumbnails and images from a PDF is one of the most used features within Razuna. But the other [...]
