mbeex··on NewPipe on Linux, Using Android_translation_layer
Mmmh, I'm using it on Android for some time now, installed as F-Droid app. Problem is, there is some friction regarding Countermeasures of YT and a new version adjusting to them. Often, I'm unable to use the alternative Client on Android for months until this is fixed. Will this be a problem on Linux too?
mbeex··on AlphaCodium outperforms direct prompting of OpenAI's o1 on coding problems
There are several others (free and certainly on par with cursor). Personally I'm using

https://aider.chat/docs/usage.html (not a vscode plugin, but with other advantages even when using this editor)

https://docs.continue.dev/getting-started/overview

https://github.com/cline/cline

was pretty good too, but it had taken on too much in its latest version 2.0.0. In other words, it is too unstable at the moment (but probably worth looking at again later).

mbeex··on Ask HN: Good Online Maths Communities?
Significant amounts of stochastic processes. Martingales, Markov, the whole stochastic Integration theory (Stratonovitch, Ito).
mbeex··on The Illustrated Transformer (2018)
Interesting read! As a mathematician I always had difficulties with AI jargon, even though I've been writing on neural networks since the late nineties.

Almost at the same time as the emergence of transformers, I had only minimal contact with the field. I was just aware of the appearance of the Vaswani paper, but only now have I returned to the subject in a way that requires more rigour. And I stumbled upon "attention" in the same way as the author. It did not help to know more about the biological model [1].

Yes, kernels. Asking myself, what software implementations of the superior colliculus or yet retina cell complexes like DS (direction-sensitive) or OMS (object-motion-sensitive) cells could provide.

mbeex··on Sleeping our way to being productive
If you measure everything by productivity, you have already lost at the beginning.

Mmmh, have you read the Quanta article? It does a good job, almost without equations.
mbeex··on Computer scientists discover limits of gradient descent (2021)
Key here: "represented"

I'm only a mathematician, no physicist. But I think to remember, that the concept of a continuous physical space becomes quite muddled at this scale.

mbeex··on Computer scientists discover limits of gradient descent (2021)
Even then. The required mapping is 'onto' (otherwise, a discontinuous counterexample would be trivial). The air particles are equivalent to the water.
mbeex··on Computer scientists discover limits of gradient descent (2021)
Show me a mathematical continuum in the real-world. And this is just the domain, nothing said about the mapping yet (the continuous function). Every analogy has its limits.
mbeex··on Baldwin Lee on his rediscovered images of the deep south
Something was triggered here, "American Pictures" by Jacob Holdt. I read the book in my late teens in East Germany. It was promoted there for ideological reasons, but the pictures were impressive and in some ways similar to those in the article.
mbeex··on Ask HN: I hate gym. How to stay in shape?
Ouch. Try classic bodyweight training (e.g. Mark Lauren's programs, they generally fit into this time frame) three or four times a week. Not to mention tabatas. Those 4 minutes can get very long...
mbeex··on I wish Asciidoc was more popular
In fact, also this claim is wrong, because there are three :D

1. https://asciidoctor.org/

2. https://github.com/asciidoc-py/asciidoc-py

3. https://asciidoc3.org/

1 and 2 seem to hate 3 (see issue trackers / web sites of all three) and meanwhile probably also vice versa. The discussion was quickly dragged into the legal realm by 1 in particular, which very obviously dampened number 3's initial enthusiasm. Additionally, 2 describes itself somewhat prominently as a "legacy processor" for Python (technically correct in the current version, but legacy's meaning here is the relationship to the new Asciidoctor-specific constructs). At the same time it promises further development but nothing usable has come out of it so far.

As a Python programmer, I would simply like to see a pure Python3 toolchain. It is quite an absurd situation at this moment. For example, my blog is supporting Markdown and ReST natively (Pelican-based). For Asciidoc - my preferred language - Pelican has a plugin, supporting different Asciidoc processors, but only at the first glance. It has also to support KaTeX. This on the other hand is no problem for Pelican's native Markdown languages (simply another plugin), but the Asciidoc plugin is too high-level. It can only use Asciidoctor in this case, requiring Ruby's KaTeX gem as an extra dependency. This gem seems to be abandoned and has compatibility issues with newer Asciidoctor versions ...

2 is no option for its installation hell alone (Asciidoc3 is pure Python, simply a pip install). I don't know, if it is able to interact with KaTeX.

From what I can see, 3 would technically offer the best initial platform for further development as a package. Could be wrong, of course.

mbeex··on Ask HN: Do You Host Your Own Email?
This has been part of my web hosting package since the nineties. I've never been interested in the low-level stuff, in this form - managed via an user interface - it's a good compromise. The only stumbling block occurred after more than 20 years in the form of DKIM, SPF, etc., the introduction of which had simply escaped me. This led to a gradual, seemingly non-causal disappearance of email, especially in communications with larger companies.

In the grand scheme of things, I really appreciate this setup. All my domains can contain an infinite number of derived addresses, which makes it possible to control outgoing information. For example, it's easy to detect and eliminate multiple types of spam sources.

mbeex··on Ask HN: Will AI put programmers our of work?
I think in this context, there exists a much more significant uncanny valley than any we know of right now. The usual example from visualization completely pales in comparison. There is no "almost" solution for any non-trivial task. And on this opposite side of the valley only humans can act.
mbeex··on Ask HN: Getting into AI?
> Laplacians, Jacobians, what, what, what???

Can you really get a PhD in anything even remotely STEM-related these days without at least knowing what those things are? I'm growing old...

mbeex··on Dozens of malicious PyPI packages discovered targeting developers
From a web page so crammed with JavaScript that it's pointless to even try to take a look at the article.
mbeex··on Why read Dostoevsky? A programmer's perspective
> Mathematics alone is sort of "sterile" when is not used within physics knowledge.

Oh no, mathematics is many things. For me - a mathematician - it started with Galois' proof about the nonsolvability of polynomial equations with degree >= 5. No physics is required for this way of thinking about symmetries. Same with number theory, primes and indefinitely more things. Many gained applications to physical problems later, many not. The latter is not a sign that something is missing.

mbeex··on How messed up was Germany's energy policy?
> Also, pretty soon energy prices in Germany might be so much lower

Jürgen Trittin (2004): Eine Kugel Eis... (costs for "Energiewende" )

There is the infamous saying, "Fusion is always twenty years ahead." But renewables seem to be trying hard to live up to that saying (AND getting more expensive along the way)

mbeex··on Habitual GPS use negatively impacts spatial memory during self-guided navigation
> Theoretically navigating with a map and compass is not hard, but I sure as shit would not want my life depending on my ability to do so.

Would you rather rely on your phone that hasn't been charged for two days?

Actually, the situation is not even a trade-off. There is no dichotomy. When you use both, you simply gain a convenient extra layer of redundancy.

mbeex··on Qt signal is ten times slower than a virtual function
Marketing. I used to work with Qt before 2000. In the beginning it was "Quasar Toolkit". Nobody cared and most people I knew - including some of the libraries developers - were fine with kju-tee.
mbeex··on A mystery of the ketogenic diet: benevolent pseudo-diabetes in mice (2019)
> It used to make me a good 2 - 3 weeks of near zero carbs to get into ketosis

AFAIK this is virtually impossible if done as required by keto (the carbohydrate limit is quite tight, it is violated very quickly without objective bookkeeping) and you also control protein intake. The liver's glycogen store lasts about a day, after which you need to burn fat (maybe some muscle glycogen).

mbeex··on A mystery of the ketogenic diet: benevolent pseudo-diabetes in mice (2019)
Those are the things that I learned as well. And some other related aspects like change in taste: sensitivity to unwanted sugar, eating (and enjoying!) chocolate with more than 90% cocoa, unsweetened whipped cream, etc. Control of cravings, and the claimed increase in concentration (but costs creativity as a downside) also occurred and were good experiences.

I still think most people should not follow the diet without breaks, deficiencies simply exist in this one as well. I like my apple and also could not stand the sight of broccoli and cauliflower for a long time after finishing it.

I'm living now according to some kind of relaxed low carb method, combined with occasional interval fasting (also allowing ketosis).

mbeex··on From Python to NumPy (2017)
I use numpy sporadically and always forget things about it. I always liked this decidedly shorter presentation of the library to reacquaint myself with the essential basic concepts:

mbeex··on Germany to Introduce Bill to Accelerate Wind Energy Expansion
> I'm living "there".

Perhaps not close enough.

- look up "infrasound" and "undercutting minimum distances", better use something else than Google for this.

- also check the requirements for the base materials: concrete, aluminium, fiber-reinforced plastic. Calculate the energy requirements for producing them.

- familiarize yourself with the space requirements (~ two acres of highly compacted soil, not including access roads)

- duration and disposal

- soil dehydration, other environment impact issues

- ... and as always of course, base load capability and storability

mbeex··on Germany to Introduce Bill to Accelerate Wind Energy Expansion
Start living there. Greetings from Germany
mbeex··on How I would start my next startup in Germany without a GmbH (2020)
> Even becoming an independent contractor is fraught with many of the same hurdles.

It depends, there is no simple entity "independent contractor". If you can run your business as Freiberufler - roughly but not quite a freelancer - you may have found a pretty lightweight framework - even compared to other jurisdictions. Simpler accounting, no need for balance sheets and therefore for a tax advisor in most cases (still recommended). Liability can be largely limited by insurance, depending on the field of business.

I'm doing this for over 20 years and I simply have no need to own any kind of corporation.

Of course, YMMV.

mbeex··on Data Science in Context – Peter Norvig's New Book
> very rarely white box.

I would not consider the attribute "rare" to be appropriate here.

For example: I regularly deal with adversarial networks, and both black- and white-box attacks are quite common there.

mbeex··on Data Science in Context – Peter Norvig's New Book
> Because the opposite of black box is clear box

Not a native speaker (never heard "clear box" as terminus technicus), but a mathematician: If it is "the (only) opposite", the relation ist symmetric. So the opposite of "clear box" is "black box" again. Skipping the injective part, "black box" would be still one possible opposite.

mbeex··on Germany: Crypto held for more than a year will not get taxed
But property tax AFAIK (contrary to Germany)
mbeex··on Germany: Crypto held for more than a year will not get taxed
Point here is, crypto - as well as Gold and Real Estate - are considered a special case of capital. Contrary to stock they have - different - 'speculation periods' (Spekulationsfristen). If they are held beyond this period, no tax is collected for gains of the sale. This was true for stock too before 2009 (unfortunately).
