ML scientist during office hours, photographer otherwise. Happily live on a mountain in Switzerland.

That was it. Thanks!

maurits··on UK Government scans all web servers hosted in the UK for vulnerabilities

The Swiss do it too. I got a very polite email in 4 languages.

ps: Anybody? [1]

maurits··on Ask HN: Where would you feel proud to work?

I do machine learning for aberration correction in the transmission electron microscope. We are not the hippest ML lab (META, Deepmind.. ), but its super cool stuff.

maurits··on Ask HN: Is it possible to open a bank account in a different country?

You could have a look at Revolut.

maurits··on Reasons you aren't updating your personal site (2020)

Thank you!

maurits··on Reasons you aren't updating your personal site (2020)

Sure: maurits.ch

maurits··on Reasons you aren't updating your personal site (2020)

I started in 2006, with a self hosted picture-a-day photoblog. It is nice to publish a photo instead of it just living on a hard drive.

Biggest source of traffic is probably my mom. I don't care, it's my living diary.

maurits··on Ask HN: Must have tools for a new MacBook

My two cents:

- Alfred (super charged application launcher)

- Dash (API Documentation Browser)

- Karabiner (key remapping)

- Keyboard Maestro (Automation tool)

- SizeUp (window manager)

- iTerm2

- 1Password (Password manager)

maurits··on Ask HN: Startup idea – disconnected, physical space charged by hour

This reminds me of Korean bath houses. They offer way more than just the spa, to disconnect. [1]

maurits··on Ask HN: In 2022, what is the proper way to get into machine/deep learning?

Stanford CS231n: Convolutional Neural Networks for Visual Recognition [1] The assignments are excellent and will let you implement a deephish network from practically scratch, before diving into modern frameworks and applications.

This is not an instant-gratification with fancy results kind of course. But put in the work, and you will learn some very cool stuff.

Or get a blending in item, like a bag from a cheap local supermarket. Also doubles as my camera bag if I feel I wondered into the wrong place.

Because Steve Jobs used to do this, e.g. introduction of Macintosh.[1]

maurits··on From Cyberpunk to Solarpunk: Technics and the Cities of the Future

Ive been to Songdo twice, and to this date it remains my most notable or bizarre asian experience. I found it absolutely fascinating.

I walked endlessly over empty 4 lane car roads, gazing up at huge towering empty skyscrapers build on undeveloped waste-land that stay dark at night. Because they are void of inhabitants.

Its to big to be walk-able for most people, the bike lanes are symbolic at best. Unlike, say Singapore, the metro stations are few and far in between, leaving but the car. Commuting to Seoul is equally painful. There is no fast direct link.

The 'smart' bit is completely lost on me.

maurits··on Ask HN: Did you change jobs during the Great Reshuffling and regret it?

I made the jump about a year ago (over WFH). Zero regrets. Love my new role.

A company is not a person, and when the going gets touch, it will not treat you like a person either.

maurits··on Ask HN: Share your personal site

https://www.maurits.ch

Everyday slice of life pictures, walking around with a small compact.

Badly needs a new backend, so open for suggestions. The self-hosted picture-a-day thing seems to be completely outdated with the rise of instagram.

maurits··on How Ebooks Have Poisoned Electronic Ink

This is the single reason I got a Kobo. And I will never ever let it connect to wifi.

maurits··on Minolta X-700 Aperture Priority Mode

Not at all. The Canon A1, born 1978, for example, has shutter priority, aperture priority and full automatic exposure [1]

maurits··on Who Got It Right: Orwell or Huxley?

Although I understand its been critiqued, I always liked the visual depiction of "amusing ourselves to death" from Postman [1], by McMillen [2]

maurits··on Locked out of 'God Mode', runners are hacking their treadmills

Kobo's used to have a memory card slot. No need to even connect it with usb.

maurits··on Locked out of 'God Mode', runners are hacking their treadmills

The short and completely correct reason as to why my e-reader has never, and will never ever, be connected to wifi.

maurits··on Locked out of 'God Mode', runners are hacking their treadmills

Ive just enjoyed another month of covid lockdown, and my bike trainer is about the only thing that kept me sane.

maurits··on Ask HN: Should I publish my research code?

Given the enormous amount of papers that come out, I personally tend to read papers that come with code (and data) first.

For me, it shows the authors are confident yet also open to critique. Which is a wonderful thing.

Secondly, I usually need the code to really understand the paper.

maurits··on Paper Website: Start a tiny website from your notebook

Random idea. How about leaving a bit of designated space on the bottom of the paper page for check-boxes or tags etc to guide the app with the processing.

maurits··on Image color replacement with numerical optimization

Pretty clever. Somewhat related, if you want to match the colours of an entire image to an other, you can use optimal transport [1]

Unrelated, the author has a very nice take on generating the organic grid from Oskar Stålberg’s Townscaper game [2].

cat: I AM THE NIGHT, THE DARKNESS

owner: That can't be right, he is called Mittens.

maurits··on I wrote a children's book / illustrated guide to Apache Kafka

Super cool, thank you. Might I request Kubernetes?

maurits··on Tool can make photos undetectable to facial recognition without ruining them

Stanford cs231n has a little demo illustrating how easy this is, if you know the model weights, called "Fooling images". In short, you backprop to the data to find out which pixels were important for the classification result. Then you ever so slightly modify these, right upon the point the model miss classifies. [1]

maurits··on Before you buy a Soviet Camera

Old soviet lenses, like the helios, can be lots of fun and fit relatively easily on a mirrorless camera.

The Chinese Holga is also a magnificent piece of plastic.

See Mathieu Stern for inspiration. [1]

maurits··on Shooting photos with an IMAX projector lens

There is a vibrant community of people experimenting with old vintage lenses. Mirrorless full frame camera's are relatively easy to make/get adapters for. See Mathieu Stern for inspiration. [1]

maurits··on Sharrows, the bicycle infrastructure that doesn’t work and nobody wants

Switzerland has stringent privacy rules, including in what other countries would consider 'public' space. Sorry, no English: [1]
