tda··on Vessel Finder
Vessel depth (draught) is usually (or always) a static number;hard coded in the ais transponder and never again uodated and thus provides zero information. The only somewhat reliable data are position and heading and their derivatives. Next to that you can get something out of the broadcast frequency, and that's about it. Of course the data can and is easily manipulated by some, and the broadcast is lossy so sometimes a few bits get lost or mangled in transit, there is no proper error correction in the protocol
tda··on Google faces €600k privacy fine in Belgium
Can someone do the math, how many seconds of profit is that for Google?
tda··on The AirPods Pro “Rattlegate”
for sure, and it is a minimum. Not sure how it works exactly, but if a device fails prematurely (within some reasonably determined expected lifetime) due to manufacturing errors you can claim warrant for longer. You might need legal counsel to actually get it though.
tda··on Yoloface-500k: ultra-light real-time face detection model, 500kb
Maybe someone else is also interested in some backgrounds on this https://news.ycombinator.com/item?id=22390093
tda··on Hundreds arrested as crime chat network cracked
Some more backgrounds: https://alarmeringen.nl/gelderland/well-gelderland/123823-li... Not sure if it was the Dutch or French police that did the actual hack, anyone have details on this?

Apparently the investigation was code named 26Lemont

tda··on Amazon Honeycode – build web and mobile apps without writing code
It's called Power Apps https://powerapps.microsoft.com/en-us/
tda··on The Coming Chip Wars
Yep, and the US gov is pressuring the Dutch gov to not export any of the next level chip manufacturing machines to China, so this chip war has already hit ASML pretty hard
tda··on Booting embedded Linux in 0.37 seconds on an ARMv7-A CPU at 528 MHz
Not OP, but from experience it could be 2009 prius.
tda··on Woodworking for Engineers
so much this, I was always able to draw simple projects in minutes. I tried fusion360 for a few minutes and figured that I would need to invest some serious time to get productive with it. I settled for the limited web version of sketchup, but it is a step back from the desktop sketchup of a decade or so ago. In some way it's kind of a relief that it's not me, there really isn't a proper alternative to sketchup of yore. Anyone looking for a startup idea here?
tda··on Pycopy – a minimalist and memory-efficient Python implementation
I haven't followed the recent developments, last time I managed to compile pycopy was end of last year. Would be nice to read about a recent comparison between the two. Is there any reason to prefer one over the other?

Just reading from that PR micropython now also runs picoweb, which is an async webframework that runs on an esp32 and I believe even on an esp8266

tda··on Pycopy – a minimalist and memory-efficient Python implementation
Good to know: pycopy is a fork of micropython. The maintainer of pycopy was the second most contributor to micropython, but at somepoint he decided to fork micropython as there were some disagreements.

As far as I'm aware pycopy has a better async implementation. Micropython probably has a bit wider adoption. A lot of libraries are compatible with both, but ymmv

Another notable fork of Micropython is Circuitpython which is maintained by Adafruit.

tda··on Major Linux Problems on the Desktop, 2020 edition
I just want to say that after upgrading to 20.04 from 19.10 something went wrong so I clean installed it. Then my Intel WiFi stopped working (even though the Bluetooth did work) and my multi monitor setup kept getting screwed up on reboot where a mousclick on the left screen would register on the right screen. I tried to file bug reports with canonical but the process seemed so convoluted I just gave up and am back to Windows and MacOS again. Maybe I'll try again in a few months, maybe not. WSL2 is working pretty well for me
tda··on Cluegen – Python Data Classes From Type Clues
I read the readme only after this comment and was surprised by how detailed this was. Why would someone put effort complicated tool, benchmark it etc. at then not really take it seriously? Until I noticed who the author was, then it suddenly made complete sense
tda··on Tetris: The Soviet 'mind game' that took over the world (2019)
What is it about nes tetris that makes it so much better? I have never enjoyed any other tetris implementation but I played nes tetris many hours as a kid and also for a bit in my twenties. Still have that nes, but haven't touched it in a decade. But even if it still works I don't have a screen for it anymore :(
tda··on Should all strings become f-strings?
Guido discussed the latest language summit on this podcast: https://pythonbytes.fm/episodes/show/179/guido-van-rossum-dr.... I believe he mentioned default f-strings were discussed and rejected.
tda··on Virtual tour of the tomb of Pharaoh Ramses VI
The dollhouse view is a nice way to zoom out without occluding what you want to see. Very impressed how smooth and detailed the tour is. So much better than streetview based tours
tda··on Ask HN: Has any progress been made on large format E-ink displays?
Also, every route can be displayed on the board, even if the next ten buses are all on a different route with better service. Better to have the next bus for every route than just the next expected buses
tda··on NASA to launch 247 petabytes of data into AWS, but forgot about egress costs
Probably there is even good competition between the cloud providers, because hosting the data means that you can sell a lot of compute time to all the users of the data. NASA choosing for AWS means that any IO intensive analysis on that data will run faster/better/cheaper on AWS.
tda··on Folding home servers overwhelmed by Corona interest
I started folding last weekend (due to it being advertised on this forum), but I keep getting: "Failed to get assignment from 'xxx': No WUs available for this configuration"

Apparently I was not the only one that started donating some compute:

> The whole world is suddenly interested in COVAID-19 and FAH has received unanticipated advertising from several popular websites so suddenly we need 6x of the infrastructure and of the staff

tda··on Why some governments appear not to be acting on the Covid-19 threat
Just a little thought experiment: If the current wisdom is actually that almost everyone will be infected eventually, wouldn't it (ignoring any ethical issues) be wiser to deliberately infect medical personnel as soon as possible, so the 5-10% of infected that need IC treatment can actually get it, before the medical system is overrun by the infected general population. In a few weeks, all doctors are immune (or deceased) so that they are much better prepared when the number of cases in the general public explodes
tda··on What it’s like to spend four and a half years in solitary confinement (2015)
Recidivism is very high when people get PTSD, no mental health support or any support whatsoever when they are let free after a decade or two. In civilised countries the prison systems main objective is preparing someone for the life after prison. In other countries revenge is the top priority
tda··on What it’s like to spend four and a half years in solitary confinement (2015)
That is really besides the point, because this article is about the third world, or should I say medieval prison system in the USA. That system is a crime against humanity in far too many ways. It is just one of the things many Europeans just don't get why you think it's acceptible. The prison system in the USA is a major cause of crime, not a solution. No civilized country has jailed up anywhere near the percentage of the population as the USA
tda··on Swedes rebelling against a cashless society (2018)
The 1 and 2 cents problem can easily be solved by agreeing to stop using them and round all transactions to the nearest. Think we stopped using 1 and 2 cent coins in the Netherlands more than 15 years ago
tda··on Fork (Git client) will soon be paid
Yes, I am also very impressed by Fork. I wondered how they could make such a polished client for free, doesn't seem very sustainable. I hope they switch to a plain and simple license model and make enough off of it to not have to resort dark patterns like advertising, data brokering and rental models. We'll see, they certainly deserve some reward for their effort!
tda··on Coronavirus may have spread undetected in US for weeks
Can anyone explain to me why in Asia the authorities seem to be going all in with extraordinary containment measures and testing larger groups of people, whilst in Europe and North America the authorities are responding very different? Almost no lock downs, very limited testing etc. In one country a single patient is enough to lock thousands in a hotel or on a cruise ship for days, while in e.g. the Netherlands everyone is assumed to be corona free. You can only get a test if you have a fever, are coughing and have been in contact with a known patient.

Either China is hugely overreacting, or we in Europe/US are in deep trouble. There is not a chance the virus can be contained here I think. In the last week he Netherlands has gone from 0 known patients to about ten, which each have probably infected multiple others. E.g. one was in the ICU (not in isolation) for a week just before diagnosed.

tda··on The Race to Build the First Sustainable Supersonic Jet
Just to clarify: in the cases of high-altitude airliners which frequently fly near or in the stratosphere, non-CO2 altitude-sensitive effects may increase the total impact on anthropogenic (human-made) climate change significantly

tda··on SciPy 1.0: fundamental algorithms for scientific computing in Python
Completely agreed, would never write it this way anymore but the example is a bit older
tda··on SciPy 1.0: fundamental algorithms for scientific computing in Python
Why is (1025, 1025, 1025) so much faster than (1024, 1024, 1024)?
tda··on SciPy 1.0: fundamental algorithms for scientific computing in Python
Here is the code in a notebook: https://github.com/Python-Meetup-Rotterdam/meetup1/blob/mast...

Gave a little presentation on my findings on using different approaches
