Scala Types: "Whenever someone in your team is confused about the exact meaning of an Option in your code, this is a good indicator that you should introduce your own algebraic data type that captures the implicit semantics of your domain"

Pagination - in depth.
 
For the SEOcampixx 2016 we tested different types of pagination and analyzed the effect on depth of levels, PageRank and CheiRank distribution.

We now compiled a comprehensive guide to explain when to you use it and how to implement a proper pagination. And of course, we summarized all our test results in great detail.

With this guide you get an extensive view on the effect of pagination on your website structure.

Why do a few modern languages opt out of exceptions? Some people argue that the concept is bad, but in this article I argue that exceptions are great and the lack of good support in some newer languages is more likely to be because implementing good exception support is hard.

A thorough critic of Single Page Apps: "Business logic does not belong in the client, unless you like having to redundantly maintain the same logic in every kind of client you support (in addition to maintaining it on the server, of course — remember that you can never trust any client). From a server-side viewpoint, the best architecture you can have is the one you could (and should) have built a decade ago: following REST principles, including stateless communication and identification of resources."

I respectfully disagree on the whole article.

Missing Empathy: "Those "Sandy Hook Truthers" harass the father of a victim because they are afraid. They are afraid their own children could be viciously gunned down in cold blood any day of the week, bullets tearing their way through the bodies of the teachers standing in front of them, desperately trying to protect them from being murdered. They can't do anything to protect their children from this, and in fact there's nothing any of us can do to protect our children from being murdered at random, at school any day of the week, at the whim of any mentally unstable individual with access to an assault rifle. That's the harsh reality."

Which reminds me of what we should teach our children: "No Fear, No Envy, No Meanness"
29 Apr 2016. They Have To Be Monsters. Since I started working on Discourse, I spend a lot of time thinking about how software can encourage and nudge people to be more empathetic online. That's why it's troubling to read articles like this one: My brother's 32nd birthday is today.

Optimized Compression: "It's a smaller file to send over the wire, and the smaller the file, the faster the decompression. This is free bandwidth, people! It doesn't get much better than this!"

Also read the comments.
02 Jan 2016. Zopfli Optimization: Literally Free Bandwidth. In 2007 I wrote about using PNGout to produce amazingly small PNG images. I still refer to this topic frequently, as seven years later, the average PNG I encounter on the Internet is very unlikely to be optimized.

Well-written and (potentially) useful.

Story
Tagline
Co-Founder of Audisto
Introduction
Starting way back in the early 80s with Basic on the C64 I quickly moved to Assembler to get things done. I still have a copy of the complete C64 ROM listing. 

After visiting Visual Basic, the Windows API, C++ and QT, I'm now happy as a web and backend developer, doing Scala, PHP, Python and still C++.

I'm the programmer of both the backend and frontend of Audisto, a web service to crawl and analyze entire web sites giving helpful insights to make them better for users.

I released PHP application framework Gyro-PHP as open source a while ago.

Gutes Essen, nettes Personal. Wir waren zu zweit da, und hatten zunächst Schnecken und Zunge mit Kapern. Beides köstlich! Die Schnecken waren in Rinderbrühe gekocht, und wir haben mehr als 30 gezählt. Auch die Zunge war reichlich. Als Hauptgang nahmen wir gegrilltes Kaninchen und gegrillte Tintenfische. Lecker! Das Kaninchen war komplett und von den Sepias gab es zwei. Beilage jeweils einige Pommes Frittes, aber nicht zu viel. Als Nachtisch machte eine Creme Caramel das Essen perfekt. Die nette Bedienung machte den Abend perfekt.
