The previous posts were mostly about cosmetics. This one is more technical, dealing with the repair and some preventative maintenance of the A501 memory expansion card. If you are curious to learn more about the retrobrighting of the computer’s case, don’t worry — I’ll get back to that at a later time.

This is the third post in a series about restoring an Amiga 500 back to its former glory. Here are all of them so far. I’ll try to remember to update this in all related entry.

In part one I described how I got and disassembled an Amiga 500 for a thorough cleaning. This part is about my first attempts to restore the grey/beige color the case had originally had, but over time had turned it an ugly yellow.

About 6 weeks ago I got the somewhat crazy idea to — just for fun — play some Amiga games. At first, my plan was to set up a Raspberry Pi 3 with an Amiga emulator, after stumbling across Dan Wood’s YouTube channel. Even though I even have a Pi 3 lying around unused at the moment, seeing Dan holding that Amiga 500 in his hands at the beginning of the video, I got all nostalgic and decided I could at least do a quick ebay search to see how much they go for these days.

Turns out, I could get my hands on one, including a memory expansion card, mouse and power brick (and a brick it is!) for  just 60€. Turns out, I would end up spending quite a bit more in the end, but still it was (and still is) a fun experience.

The whole story is probably way too long for a single post, so I may end up splitting this into at least two parts, but I feel it is …

The website or mobile app is the storefront for participating in the modern digital era. It’s your portal for inviting users to come and survey your products and services. Much attention focuses on front-end development; this is where the HMTL5, CSS, and JavaScript are coded to develop the landing page that everyone sees when they visit your site.

But the real magic happens on the backend. This is the ecosystem that really powers your website. One writer has articulated this point very nicely as follows:

The technology and programming that “power” a site—what your end user doesn’t see but what makes the site run—is called the back end. Consisting of the server, the database, and the server-side applications, it’s the behind-the-scenes functionality—the brain of a site. …

Auf der FrOSCon 10 in St. Augustin habe ich kürzlich ein Update zu unseren Erfahrungen mit dem Thema "Private Cloud mit OpenSource" gegeben. Leider sind noch nicht alle Probleme, über die letztes Jahr berichtet wurde, behoben, aber wir sind schon ein gutes Stück weiter und haben neue Stolperfallen gefunden und z. T. auch überwunden.

Leider habe ich mich mit der Zeit ein wenig getäuscht, da ich den Talk vorher schon einmal in gekürzter Form in 40 Minuten unterbringen musste, aber in der Präsentation den Countdown für die FrOSCon wieder auf 60 Minuten zu stellen vergessen hatte. Zwischenzeitlich war ich deswegen der Meinung, ziemlich hinterherzuhängen... Hoffe, es macht trotzdem ein bisschen Spaß, so blieb am Ende mehr Zeit für Fragen und Gespräche :)

The call for participation at Percona Live MySQL Conference and Expo 2014 is now closed. There have been more than 320 submissions, and this will keep the review committee busy for a while.

One important point for everyone who has submitted: if you have submitted a proposal but haven’t included a bio in your account, do it now. If you don’t, your chances of being taken seriously are greatly reduced. To add a bio, go to your account page and fill in the Biography field. Including a picture is not mandatory, but it will be definitely appreciated.

Although the CfP is closed for tutorials and regular sessions, your chances of becoming a celebrity are not over yet. The CfP is still …

After a long pause in the speaking game, I am back.

It's since April that I haven't been on stage, and it is now time to resume my public duties.

• I will speak at MySQL Connect in San Francisco, just at the start of Oracle Open World, with a talk on MySQL High Availability: Power and Usability. It is about the cool technology that is keeping me busy here at Continuent, which can make life really easy for DBAs. This talk will be a demo fest. If you are attending MySQL Connect, you should see it!
• A happy return for me. On October 27th I will talk about open source databases and the pleasures of command line operations at …

Introduction

Object-relational mapping (ORM) frameworks have been around for several years now and for some people, ORM is already outdated by now. As we have seen with other technologies and concepts before, PHP is not exactly what we call an early adopter among the programming languages. Thus it took some time for ORM to grow up in the PHP context.

There have been some frameworks before Doctrine 2 that implement ORM (remember e.g. Propel) specific tasks but most of them lack the required maturity to be used in large projects. With Doctrine 2, PHP takes a huge step into the right direction Doctrine 2 is fast, extensible and easy to use.

This article will take you on a tour through the main concepts of Doctrine 2 in the first part and then explain how to use it in a real world application in the second part. Since at the time of writing …

The Danish "julehjerte" is apparently a Danish/Northern Europe Christmas tradition (at least according to Wikipedia). But hopefully people outside this region will also be able to enjoy this variant:

I have been doing "julehjerter" ever since I was a small kid, and every Christmas try to do something different with it. As seen above, this year I decided to combine the tradition with the MariaDB logo, and I am frankly quite pleased with the result :-)
