Atmospheric absorption, spectra, units and code: companion page to the global warming explanation post
This is a companion page to my blog post on global warming (which is currently not yet ready).
I put up this post already as a teaser for my upcoming global warming post, which desperately needs expert review before I dare put it online. If you are an experienced climate/atmospheric scientist, would you please consider helping me out? Please email me on bert@hubertnet.nl if you can spare the time to skim my work for gross errors.
On Climate Change and (Active) Climate Management
Nothing on this page is factually controversial. However, many things in this post make for uncomfortable reading. And, climate discourse is now so politicized that many factual statements are taken as dog whistles. For example, in what follows I will state that climate has always been changing, and has in fact never been stable for very long.
This is 100% true, but people interpret this as if the writer means that our current climate change is not caused by human beings, or is nothing to worry about.
On Being Useful
I wrote this piece after an early-career friend of mine asked some very good questions on how to be useful. Since this is a thing I struggle a bit with myself, I thought it worthwhile to write up my thoughts. Note that I fully understand that not everyone has the luxury to think about their career like this – you first have to take care of yourself and family before you can start fretting about if your working life is saving the world!
Welcome to the BAG: The Dutch Building and Addresses database
Recently, I wrote a small open source tool to make the official Dutch national address & building database more accessible. More about the tool below, but first an introduction.
Last data update: 2024-12-14
If all you need is an up to date CSV file of all Dutch addresses, their zipcodes and coordinates, scroll down to the end. If all you need is a web service, try https://berthub.eu/pcode/2513AA/14. For more details (including a live demo), do read on.
Waarheen met energie: wat is het plan?
"Best een goede samenvatting eigenlijk" — een daadwerkelijke energie-expert
Op 10 juni 2023 is dit artikel uit 2022 ge-update met een extra stukje over waterstof en waar het niet voor geschikt is, plus wat meer over kernenergie, en over minder energie verbruiken.
Sinds een tijdje maak ik grafiekjes van hoe Nederland aan z’n elektriciteit komt. En soms ben ik daar dan enthousiast over, zeker als de wind waait en de zon goed schijnt.
The Dutch government wants to automatically and administratively gain permission to target victims of hackers
This is a mirror of the original about:intel post, since the about:intel server is sadly sometimes overloaded. Also do read the opposing view from Jan-Jaap Oerlemans and the reflection by Lotte Houwing
The Dutch government is proposing adding a lex specialis to its existing intelligence and security services act. This addition significantly changes the scope of many powers and also extends who they can be applied to.
A draft of an English summary of this proposed law can be found here.
Reflectie rondetafelgesprek en technische briefing wet cyberoperaties
Gisteren (5 april) was er een technische briefing van de AIVD en MIVD over de tijdelijke wet cyberoperaties, gevolgd door een rondetafelgesprek met deskundigen. Vorige week was er een technische briefing door de toezichthouders TIB en CTIVD.
Mijn spreektekst met veel klikbare voetnoten ter verduidelijking staat hier. Er was een goeie opkomst van geïnteresseerden en Kamerleden, en er waren goede en goed geïnformeerde vragen.
Verder schreven de media over de bijeenkomsten: De Correspondent, NRC, Trouw, AD, GeenStijl
KI: Umwälzung für die Wirtschaft garantiert
Vielen Dank an Lili Laguna für diese Übersetzung diesen niederländischen Blog-Beitrag. English version.
Jeder überschlägt sich mit Vorhersagen über KI. Sie wird uns von stupider Arbeit befreien, sie wird unsere Bildung zerstören, wir alle werden nichts mehr lernen müssen, weil die KI es für uns tun wird, Kriminelle werden uns mit ihr austricksen, Gauner werden mit ihr unendliche Mengen an Desinformation erzeugen, und die KI wird entkommen und in der realen Welt gefährlich werden.
AI: Guaranteed to disrupt our economies
This is a machine-aided translation of this Dutch post. Und jetzt auch auf Deutsch verfügbar!
Everyone is tumbling over themselves making predictions about AI. It’s going to free us from menial work, it’s going to dismantle our education, we all won’t have to learn things anymore because the AI will do it for us, criminals will trick us with it, crooks will create endless amounts of disinformation with language models, and the AI will escape and become dangerous in the real world.
AI: sowieso ontwrichtend
Update: This article is now also available in English. Und jetzt auch auf Deutsch!
Iedereen buitelt over zichzelf heen om voorspellingen te doen over AI. Het gaat ons bevrijden van dom werk, het gaat ons onderwijs ontmantelen, we hoeven allemaal dingen niet meer te leren want de AI gaat het voor ons doen, criminelen zullen ons er mee bedonderen, boeven gaan er eindeloze hoeveelheden desinformatie mee maken, en de AI zal ontsnappen en in de echte wereld gevaarlijk worden.

After having completed this series of blogposts (well done!) you should have a good grounding in what deep learning is actually doing. However, this was of course only a small 20k word introduction, so there is a lot left to learn.
Unfortunately, there is a lot of nonsense online.
Hello Deep Learning: Doing some actual OCR on handwritten characters
This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub!
The previous chapters have often mentioned the chasm between “deep learning models that work on my data” and “it actually works in the real world”. It is perhaps for this reason that almost all demos and YouTube tutorials you find online never do any real world testing.
Hello Deep Learning: Dropout, data augmentation, weight decay and quantisation

In the previous chapter we found ways to speed up our character recognition learning by a factor of 20 by using a better optimizer, and a further factor of four by cleverly using threads using a ‘shared nothing architecture’. We also learned how we can observe the development of parameters.
Hello Deep Learning: Hyperparameters, inspection, parallelism, ADAM

In the previous chapter we successfully trained a network to recognize handwritten letters, but it took an awfully long time. This is not just inconvenient: networks that take too long to train mean we can experiment less. Some things really are out of reach if each iteration takes 24 hours, instead of 15 minutes.
Hello Deep Learning: Convolutional networks

In the previous chapter we taught a network of linear combinations and ‘rectified linear units’ to recognize handwritten digits reasonably successfully. But we already noted that the network would be sensitive to the exact location of pixels, and that it does not in any meaningful way “know” what a 7 looks like.

In the previous chapter we described how automatic differentiation of the result of neural networks works.
In the first and second chapters we designed and trained a one-layer neural network that could distinguish images of the digit 3 and the digit 7, and the network did so very well.
Hello Deep Learning: Automatic differentiation, autograd

In the previous chapter we configured a neural network and made it learn to distinguish between the digits 3 and 7. The learning turned out to consist of “twisting the knobs in the right direction”. Although simplistic, the results were pretty impressive. But, you might still be a bit underwhelmed - the network only distinguished between two digits.
Hello Deep Learning: actually learning something

In this chapter we’re going to take the neural network we made earlier, but actually make it do some learning itself. And, oddly enough, this demonstration will again likely simultaneously make you wonder “is this all??” and also impress you by what even this trivial stuff can do.
Hello Deep Learning: Linear combinations

In this chapter we’re going to build our first neural network and take it for a spin. Weirdly, this demonstration will likely simultaneously make you wonder “is this all??” and also impress you by what even this trivial stuff can do.
The first part of this chapter covers the theory, and shows no code.
Hello Deep Learning: Intro
This page is part of the Hello Deep Learning series of blog posts. Also, feel free to skip this intro and head straight for chapter 1 where the machine learning begins!
Deep learning and ‘generative AI’ have now truly arrived. If this is a good thing very much remains to be seen. What is certain however is that these technologies will have a huge impact.
Up to late 2022, I had unwisely derided the advances of deep learning as overhyped nonsense from people doing fake demos.
