A short note about the Dropbox authentication bug

June 22nd, 2011 Comments off

May you’ve heard about the Dropbox authentication bug (read it here, here or for the german readers here) wich has appeared on last Monday, the 20th June. There was a lot of utter confusion about it… and a lot of users were angry and very unhappy of how Dropbox has handled the problem. Hey people! Human error happens! Even in the Software development or in communication… you may know what I mean Wake up!

I’m a frequent-user of the Dropbox service because it helps me to access some of my files everywhere or share it easily with others. Any file you save to Dropbox is instantly saved to your computers, phones, pad and the Dropbox website. It is very useful to me. I’m not crying about the security glitch… why? Because I’m not stupid enough to keep anything sensitive on Dropbox. If you need some kind of security please install e.g. Truecrypt and place the virtual encrypted disk in your Dropbox. But keep in mind… it’s still in the “cloud”.

All of this storage “cloud” services have sooner or later some issues with security or other unforeseen problems – remember Amazon’s cloud-based EC2 (Elastic Compute Cloud) failure? That can happen to anyone. Even Apple’s iCloud, which I think is really great, will not be just the thing… I’m sure. Honestly. If you need sensitive data immdiatly available to you anywhere in the world, put it on an SD card and carry it in your pocket or wallet.

I guess the Dropbox quality assurance (QA) will try hard to avoid that these things happen again. They are surely embarrassed about such a mistake (hopefully!). So be cool, calm down, take a coffee, enjoy your life, use your Dropbox or another service of your trust.

 

In the beginning was the Word “Scrum”

December 22nd, 2010 Comments off

Yesterday I took another wander through the web and found a short article named “understanding Scrum” at the pm-blog.com. Dr. Stefan Hagen has linked a really good presentation named The Zen of Scrum by Jurgen Appelo which is available on Slideshare.net. This presentation is a really good start to get an idea of Scrum. Some of you may heard about it, some may not.

Scrum is an iterative, incremental methodology for project management often seen in agile software development.

Although Scrum was intended for management of software development projects, it can be used to run software maintenance teams, or as a general project/program management approach.

By clicking through the presentation I was remembering my first contact with Scrum. So I decided to write this little blog entry.

Before I’ve started at AdScale I read a lot of stuff about Scrum and agile project management methods, but I was always caught in the typical “waterfall” process. Unfortunately I’d never had the chance to set up any working agile processes as employee in my former company. Advice: Everyone should be committed to break the mould of old behaviors. I would say there was no ill will intended but we’ve never made it to implement a new methodology to get our software development projects done.

That changed in February 2008 when I have started to work at AdScale. From the CTO, my colleague and shining example Manfred Friedrich, I heard that there was a scrum process basically established but – same story – it was more or less ignored by the business team. No offense guys! Haha! I’m just talking about the old times. Now everyone at AdScale is committed to our agile project processes even though some people might wish there would be another approach of getting the things done.

First I might have to explain the constellation we have since the beginning at AdScale. There is the headquarter in Munich, Germany, which is running the whole business (product owner) and the AdScale Labs, our development team (scrum masters and the teams), is located in ChristChurch, so that is far, far away on an island named “The South Island” of New Zealand. Distance between the teams: more than 18.500 km and a time difference between 10 and 12 hours. Yeah. Sounds weird? It is. Hilarious. How this constellation was born is a complete other story.

If you are familiar with the Scrum methodology you may now thinking about the common stuff like daily scrum meetings, task boards and what ever. Forget it. Over such a distance there is no way to stick the teams closely enough together, but… you can try. We tried it and we found a way – over the years – to establish our agile processes which serves its purpose. I would lie if I say that the process is “finalized” yet, because from time to time it is mandatory to review the whole process and initiate some slight modifications. All in all it works really good for us and often an outstanding person is wondering how we manage it to get the things done (so fast)… given that the teams are so far away from each other.

Actually we are working with two product owners (product developer) in Munich and two scrum masters and four teams, including the “product team”, the “adserver team”, the “database team” and the “quality assurance team”, in ChristChurch. Meanwhile we are able to deploy every two to three weeks a feature/improvement set which is boosting and increasing our business or helps our customers to use the AdScale platform for their personal goals. The remarkable speed and the quality is based on every single team member. Within two years we managed it to built germany’s biggest marketplace for online advertising and I’m proud to be a part of the team which made it happen.

If you are interested in the way we work and what its all about, than please let me know. Maybe there are some suggestions you could use for your business. Maybe there are some interesting stories how you achieve to work with your teams located in different countries and time zones. Let me know by a comment. Thanks.

The growth of AdScale

November 16th, 2010 1 comment

Since August 2008 AdScale is officially measured by comScore. Every month we have renewed the actual comScore numbers on the AdScale website. If you put the historical data in a graph the development of AdScale looks really awesome. I’m sure this will be not the limit. If I’ve some time within the next days I’ll write a short recap of the year 2010 that is about to draw to a close. You can be sure that we’ll have some really nice things on the development roadmap for 2011, but I’ll don’t give anything away for now!

At October 2010 AdScale hit the first time a reach of more than 70% of the german internet users. We are pretty sure that in November 2010 we achieve again a all-time-high.

In October 2010 more than 38 million unique user have seen an advertisement which was delivered through the AdScale marketplace.

In August 2009 we hit our all-time-high regarding the supplied page impressions where advertisement were delivered through the AdScale marketplace. You may have recognized the little drop in September and October 2010. This has traditional to do with the general growth of online advertisement in this period. The experience shows that in the last quarter of the year the publisher websites do much more sell their own inventory directly to the advertisers, which reduces the available inventory in the marketplace but increases the max.bids for a campaign and the coverage of a available ad slot.

Heading straight to 2011

A year ago I wrote…

It’s a long time ago since this page was updated. In the past you have found a lot of private stuff – and honestly – often nothing.

Here we go again. You’ve found often nothing. We’re now heading straight to 2011 and I didn’t manage it to write a minimum of one interesting blog entry in 2010. What a pity… but at least it was one of the constant things this year. This meant also that I didn’t have the time to concentrate on other things beside AdScale, my family and friends. So its not so bad. I’ll give it another try within the next weeks and months. In the meantime you can follow me at twitter. Different than usual I managed it there to write something you are might be interested in.
