fatuna··on Benzene’s bond lengths corrected
Fun fact, even though most of the world pronounces it "angstrum", "Ångström" should actually be pronounced "ongstrum" (as the Swedish still do).
fatuna··on Undefined claims 4.5-min flight for its “silent” ion-propulsion drone
This is what we used to call a "lifter". I did a project on them in high school. Very fun to do, since you use a very high voltage. Our physics teachers were very enthusiastic and helped us a lot, all the other teachers kept a very safe distance. Another fun aspect; because of their obscureness, doing any research on lifters led almost directly to ufo and anti-gravity websites. Based on what I saw on our lifter, generating enough lift to carry actual cargo would require a huge amount of power, or a huge leap in efficienty of their ion-generation. Interesting development, I'll keep an eye on them.
fatuna··on Effectless but expensive. Or be careful with type hints in Python
Benchmarking is hard to do well. Benchmarking on modern machines is very hard (dynamic clocks, caching, more). Benchmarking on code that runs in less than a milisecond is very very hard. If you care about this performance you probably should not use Python. I'll take better checked, more readable Python over faster Python any day.

On a similar note, The Netherlands are descibed as food importer. Sure we import a lot of food, but we export a lot more[1]!

fatuna··on On my resignation as regulator of the Dutch intelligence and security services
In the Dutch version (not sure about the English one), he mentions that there's always a fast-track if needed.

Futhermore he says, agencies are incentivices to not overload 'permission' regulators. For 'forgiveness' regulators they have either no such incentive, or worse they might burry those regulators in work so they can't do their work properly.

I don't think he means to say agencies shoud be stopped, more as they need to be kept in line.

fatuna··on Rapamycin, drug used in cancer therapy, emerges as powerful anti-aging remedy
I think this is a great example of "what's good for the individual, is bad for humanity as a whole". Imagine we'd discovered a drug that adds 100 years to a persons natural life. Now imagine this drug was discovered 100 years ago. J.D. Rockefeller and the likes would still be alive and influencing politics. I can't even begin to think how much humanity would stagnate after such an invention.

See also the Planck principle: "A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it"

fatuna··on Job switchers are earning a lot more than those who stay
They meant per month. In NL we tend to discuss salaries per month. This excludes the mandatory "vacantion bonus", which is about a months salary. 2500 * 13 makes 32500 a year. So not far off from your figures.
fatuna··on Stupid hacks from stupidhackathon.se
Sound like a great idea. I would like to join!
fatuna··on DeepTraffic is a gamified simulation of typical highway traffic
As far as I know, it is common in Europe to only overtake on the outer lanes. In the US however, there are no such rules.

It does seem like a good idea to me.

fatuna··on Physicists believe they can create matter from colliding photons
This article appears to be 1,5 years old. So at least the 1 year deadline was missed.
