lorenzfx··on Germany is offering a summer of cheap trains
Mostly by spending more money. Especially France and Japan built special rails only to be used by high speed trains. While those exist in Germany, there are less of them and they mostly don't reach from station to station but instead near the city centers high speed trains share rails with slower trains.
lorenzfx··on Inkdrop: Organizing your Markdown notes made simple
If you live in the Apple ecosystem you could use something like FSNotes and icloud for 7$ for FSNotes plus 1$/month for icloud.
lorenzfx··on Inkdrop: Organizing your Markdown notes made simple
I'm also always coming back to vimwiki after trying something else (mostly because I'm so used to (n)vim). I still want to give zk [1] a try though (but it's also vim based).

The one killer feature for me would be a gui for neovim that can display images. (Inserting images from the clipboard works with clipboard-image.nvim.)

lorenzfx··on Inkdrop: Organizing your Markdown notes made simple
The space of markdown based note taking apps is getting more and more crowded. I'm wondering how many more are sustainable, especially as many free (and open source) ones are available.

Regarding Inkdrop: this page really doesn't tell me what's their USP, why would I use this over something like Obsidian or Roam (just to name some examples)?

lorenzfx··on Mercedes-Benz says Level 3 self-driving option ready to roll
While the specs sound very underwhelming at first (geo-fenced on some roads, very low speeds, no bad weather), they seem to be so confident in their system, that they will take responsibility for the car when in autopilot. AFAIK, no other manufacturer does this for their systems (which capabilities they often make rather wild claims about).
lorenzfx··on You Should Compile Your Python and Here’s Why
Does anyone have any personal experience in applying mypyc on type-hinted, but otherwise not specially optimized python code? I'm especially interested in what kind of performance speed-ups could be achieved.
lorenzfx··on You Should Compile Your Python and Here’s Why
Especially reading and understanding the "moderately" optimized Python version is a lot harder than reading the C version.

Also I really dislike python optimization tricks like `output = stdout.buffer.write`.

lorenzfx··on Elon Musk makes $43B unsolicited bid to take Twitter private
You live in a very different world than I if for you, the associating of Twitter with Mr. Musk improves Twitters image.
lorenzfx··on Elon Musk makes $43B unsolicited bid to take Twitter private
You are implying, that current staff of twitter is not effective. How do you get to that assessment?
lorenzfx··on Europe is investing heavily in trains
Sure, if you consider 3.5% of all green house gases miniscule.

lorenzfx··on Europe is investing heavily in trains
According to this [1], taxes on gasoline are much higher than 40 cents/litre (50 cents in Spain, 68 cents in France).

If you buy a train ticket in advance, you definitely are in that price scale. I looked up train rides one month in advance [2] and a ride from Madrid to Spain is now 175€ to 210€, right in the range of the train ride.

But hopefully, Europe-wide CO2 taxes will start to price in externalities and remove the finger from the scale in favor of flights.

lorenzfx··on Europe is investing heavily in trains
> Here in Germany, for as long as I can remember, the government praises itself every year for investing as much in rail as never before.

Unfortunately, that's not true (the investment part). In preparation for the IPO (that never happened because of the crash) Deutsche Bahn was heavily tuned for profit since the mid 90s which led to a massive decrease in investment. As rail infrastructure has a rather long service life, a lot of those cost-cutting measures have only beginning to be felt rather recently. Now not only do the investments that have not been made have to be made up for, but the funding gap has caused the infrastructure to decay even further.

Also, a lot of money has been spent on vanity projects like Stuttgart 21, instead of much-needed extension of freight lines like the one in the upper Rhine valley.

lorenzfx··on Germany boosts renewables with “biggest energy policy reform in decades”
This.

As I commented recently on another thread:

This was done on purpose. There was the hope, that strong economic ties would make war between Germany and Russia impossible. While it now looks really stupid, it worked really well between Germany and France after World War II (first with European Coal and Steel Community and then later with the European Union).

lorenzfx··on Germany has seized control of Gazprom Germania
I'm not sure if this is the right answer.

The prevailing political view, was that strong economic ties would make war and violent conflict between Germany and Russia impossible. This is basically what happened intentionally and successfully between Germany and France after World War II first with European Coal and Steel Community and later the European Union.

lorenzfx··on Future Combat Air System (FCAS)
As commented below:

That broomstick example gets paraded around a lot, but this was on a vehicle that wasn't supposed to have a gun in the first place.

There is a lot of valid criticism on the readiness of Germany's armed forces, this isn't one.

Did you read the first article?

Why care about the %? What really matters are the capabilities, no matter the cost.

Which is what the article describes.
lorenzfx··on Some neurons are active when adding, others when subtracting
Sorry.

Principal Investigator See https://en.m.wikipedia.org/wiki/Principal_investigator

lorenzfx··on Some neurons are active when adding, others when subtracting
The PI was also involved in an earlier study [1, 2], that found "Jennifer Aniston neurons", i.e., neurons that get activated when the proband gets shown an image of Jennifer Aniston, but not activated when shown the image of another celebrity.

It's probably not that surprising, that other cells are active during other specific activities and inactive during others.

Anyway, it's fun seeing my old institute featured on hn.

lorenzfx··on It’s great to be a consultant
This very much mirrors my experience.

I would like to add, that for people with little professional experience, working in a consultancy can accelerate the rate at which work experience is gained (by working on different projects, perhaps at different clients and with different technologies). This also expects a lot of commitment and willingness to learn (as pointed out in the article).

As an added benefit, one has the chance to look at the inner workings of a lot of different companies if one doesn't want to stay in consulting forever.

lorenzfx··on The money printing press that is chip maker TSMC
The acquired podcast episode on TSMC gives some more insight into TSMC's interesting history. Highly recommended.

lorenzfx··on Ask HN: News site that provides world updates only when relevant?
I like the economist, for keeping up with the latest news especially the brief updates on the first 2-4 pages.
lorenzfx··on Germany locks down unvaccinated people, as leaders plan to make shots compulsory
I'm surprised to find this many anti vaxxers on hn. I would have expected that the community was a lot more rational.
lorenzfx··on Costly Airbus paint flaw goes wider than the Gulf
It did, at least as a proverb. E.g. In German there is a saying "der Kunde ist König" (customer is king)
lorenzfx··on Europe has now created more $1bn ‘unicorn’ companies than China
True. Same goes for the US when you exclude California.

And yes, the UK isn't part of the European Union anymore, but it's still part of Europe.

lorenzfx··on The daunting task of writing longhand and why you should do it
"Citation needed" for most of the claims.
lorenzfx··on Who owns the German DAX? [pdf]
Too small for what purpose?

Also, the US' GNP is about 5 time that of Germany. If the NASDAQ100 is "big enough", the DAX should be big enough as well.

lorenzfx··on Ask HN: Where are the job resources for science graduates?
I'd suggest looking for data science roles. Especially consultancies hire a lot of people right out of university. Consulting is also a great way of getting a lot of experience quickly.
