[TSTIL] SnelTrein

2009 - SnelTrein

While I was off studying Computer Science the smartphone revolution kicked off. Being an Apple hater, I got the first Android phone I could get my hands on: the T-mobile G1. Loved it and still think killing physical foldable keyboards was a shame. I had all kinds of ideas for apps, for some reason most of them revolved around trains. Like a GPS alarm clock that would wake you up when you got close to your destination.

I traveled by train a lot, and planning a trip or checking train times was a pain. I decided to build a train times app, but the name Trein was already taken, so I named mine SnelTrein. The Dutch name for high-speed trains. It was a simple wrapper around the mobile website of the NS (Dutch Railways). My app was super fast and super simple in the UI, as it remembered your trips. Your most often used trips were always on top. Once the app opened, it was literally one click to see the departure times of any of your 5 most used trips. I loved it, users loved it, and it grew to 3000 installs.

After some time, the NS released their own app, and I figured they are probably not scraping their own mobile site. After MITM'ing the traffic, it turned out they indeed had an XML based API which was password protected but they did not use HTTPS. I created a blog post post about this, submitted it to Dutch tech website tweakers.net. It was posted to the front page and I got my 15 minutes of Dutch tech fame. https://tweakers.net/nieuws/73527/ontwikkelaar-verkrijgt-toegang-tot-ns-api-voor-treintijden.html

I stopped maintaining SnelTrein because the NS app caught up a bit and is good enough. Early in 2022 I also switched to an iPhone SE from 2016 because Android phones are so big.

"Security Is Our Top Priority" is BS

First published on
A couple of years ago I was asked to give a conference talk about software security. Well, actually I wasn't really asked, my company bought a sponsorship package with a speaker slot and I replied to the internal email asking for volunteers  🤣  Anyway, while preparing my talk, I realized a couple of important points about security that have not left my mind since: Security is limitless . You can always spend more effort to make things more secure. The same goes for quality, safety, employee happiness, etc. The needs of security are opposed to the needs of a convenient user experience . Improving one typically hurts the other. Now some organizations say "Security is our #1 priority". Really? You want to make something that has no limits your number one priority? I mean security is a good thing, but this seems a bit too simple? In fact, hollow marketing claims like that can make me a bit angry. In this post I'll help you understand what to make of statements like that...

AI programming tools should be added to the Joel Test

First published on
Here's a wake-up call to all CTOs: AI programming tools are getting freaking amazing and if you don't allow your teams to use them somehow, it will bite you in the ass in a couple of years. You will be slower and you will lose your best people. The infamous Joel Test is a list from the year 2000 of 12 things all great software companies do. Since then most companies have implemented Git and CI/CD, checking of three items, so we have some space left in the 2024 update ;) I believe "Do you allow your developers to use AI assisted development environments?" is a necessary addition. I get that you don't want your source code to end up on some OpenAI / Microsoft / Github server somewhere, sure, but find a way to use your own models or learn to live with it. Note that this is often not the same as "#9 - Do you use the best tools money can buy?" as blocking AI tools is about data security, not money. So why do I think developers need AI programming tools? I...

The long long tail of AI applications

First published on

Last year multiple companies asked me for advice. " We are evaluating this AI powered product, but do you think it makes sense at all? It seems a bit niche and we think ChatGPT might make this entire thing obsolete soon. " Long tail - credit to Wikipedia My answer so far has always been: "No, bare LLMs are not going to compete with this product." I think that people are failing to understand the distinction between different classes of AI companies. I see it like this: Foundational AI - creating models like GPT-4 (text), Sora (video) etc. Applied AI - using existing models to create smart applications. Note that there are also companies not focusing on AI - they will start lagging behind, let's forget about them ;) There are orders of magnitude  (!)   more companies that will deal with Applied AI than Foundational AI, and they will be very busy for decades to come. Here's why: To get the most out of LLMs, you have to ask the right questions. LLMs have acc...
