Issues With Electronic Machine Readable Travel Documents

February 3, 2016

Most of us have passports, and most of these passports are by now equipped with chips that store some data, including fingerprints. But six months ago I had no idea how that operates. Now that my country is planning to roll out new identity documents, I had to research the matter. The chip (which is […]


Microservices Use Cases

January 19, 2016

A few months ago I wrote a piece in defence of monoliths and then gave a talk about it. Overall, one should not jump to microservices, because the overhead and risk are much higher than any professed benefits. But there I left out some legitimate use cases for microservices. These use cases may not be […]


Testing: Appetite Comes With Eating

January 11, 2016

I’ve written a lot about testing. Some tips on integration tests, some how-tos, some general opinions about tests. But I haven’t told my “personal story” about testing. Why are tests needed should be obvious by now. It’s not all about finding bugs (because then you can use an excuse like “QAs will find them anyway”), […]


Electronic Identification

December 1, 2015

On the conference where I spoke about e-voting, I had another talk that focused on e-identification (which is a mandatory step for e-voting). It is in Bulgarian and EU context, given the new EU Regulation that aims at cross-border e-identification. Nearly 2 years ago I did a campaign for that, not knowing the European parliament […]


A Problem With Convention-Over-Configuration

November 15, 2015

Convention-over-configuration is a convenient thing. Instead of writing tons of configuration in xml/yaml/json/whatever, you simply know that something will have a given default value. For example, the restful endpoint URL may have a value of /class-name/method-name, or a join table will be named mainEntity_joinField. A “view” can be populated by default with the input parameters […]


E-voting [presentation]

November 13, 2015

Last week I gave a talk on the OpenFest conference about (remote) e-voting (or internet voting/i-voting). The talk was not in English, but here are my translated slides: I’ve addressed some of the topics from the presentation in a previous post. Overall, it’s a hard problem, with a lot of issues to be addressed and […]


In Defence of Monoliths

October 22, 2015

The first Microservices talk I attended was a year and a half ago. My first reaction was “why is that something new?”. Then I realized it is already getting overhyped, so I listened to some more talks, read a bit more articles, so that I can have a good reason not to like the hype. […]


Why All The Fear of Electronic Voting?

October 2, 2015

Due to an upcoming referendum in Bulgaria about whether we want “remote electronic voting”, I, as a technical person, and at the same time, as government adviser, argue a lot about electronic voting. A year and a half ago I’ve given a very brief overview of what I think has to be done and is […]


Common Sense Driven Development [talk]

September 17, 2015

A few months ago I spoke on a conference (jPrime) about common sense driven development (and what it isn’t). Here’s the video: And here are the slides: As you’ll see, I am not a very good and engaging speaker. I hope at least the content is meaningful, although this time it felt a bit chaotic. […]


The “Software Engineer” Mindset

September 7, 2015

What is a software engineer? And what is a senior software engineer? Many companies define a “senior software engineer” as a person who has spent more then 6 years as a programmer. And that’s not always correct. The other day I was asked whether I recommend becoming a “generalist” or a “specialist”. Whether one should […]
