Almost 80% of Private Day Traders Lose Money
A few months ago, I wrote a blog post about how penny auction sites make you money. As a reaction, some readers sent me links to day trading brokers that promise easy returns. These brokers allow private investors to hold stocks or currencies positions for a short time which makes it possible to speculate on small…

Penny Auctions
Unless you use an ad blocker, you probably notice ads for penny auction sites from time to time. They usually advertise with sketchy messages like “iPhone sold for $14.21.” They can sell iPhones such low prices because of their unusual auction system where each bid increases the auction price by only one cent. This…

The Elegance of Deflate
A little while back I found need of a PNG loader for a small project of mine . Being a complete tool I of course decided to write my own -- after all, why save yourself effort when there are still wheels waiting to be reinvented? You can check the source to the inflater code here if you so like - it's quite cleanly…

Mainframes as a lifestyle choice
I started working at IBM last year on mainframe compilers with the goal of making mainframes feel a little more modern. Hence, a lot of my time is spent in z/OS . The interface I use to z/OS is Unix System Services (USS, a.k.a. the command line), but if I were up for bucking the whole moderm thing, I could break out…

Learning from Ada
This is a cautionary tale. One of youth and a lesson I eventually learned but still often don’t heed. About how sometimes, the tool that is easiest to get started with isn’t the tool that will make your job the easiest.

The meaning of trust in the age of Airbnb
I am on holiday in Bavaria, where, in between the beer and schnitzels, I have been contemplating the nature of trust. A rather old-fashioned guest house happily took our reservation and let us run …

Fixing JSON
I’ve edited a couple of the JSON RFCs, and am working on the design of a fairly complex DSL, so I think I can claim to have dug deeper in the JSON mines than most. We can easily agree on what’s wrong with JSON, and I can’t help wondering if it’d be worth fixing it.

Playing with Syntax
One of the things I love about Lisp is that it gives you the ability to change and mold the syntax of the language to what you need. In this post I want to look at the evolution of a little macro I've been playing around with for a while now.

Sad Trombone Exoplanet Reality Check
Some people on the internet are getting very excited at the (unconfirmed) reports of an "Earth-like" exoplanet orbiting Proxima Centauri , a mere 4.25 light-years away from Earth. If correct, the planet is orbiting in the liquid water zone around our nearest stellar neighbour and is of the same order of mass as the…

Less stress, more productivity: working fewer hours is good for you and your boss
There’s always too much work to be done on software projects, too many features to implement, too many bugs to fix. Some days you’re just not going through the backlog fast enough, you’re not producing enough code, and it’s taking too long to fix a seemingly-impossible bug. And to make things worse you’re wasting time…

Removing the PowerShell curl alias?
PowerShell is a spiced up command line shell made by Microsoft. According to some people, it is a really useful and good shell alternative. Already a long time ago, we got bug reports from confused users who couldn't use curl from their PowerShell prompts and it didn't take long until we figured out that Microsoft ……
