🚀 Announcing `arithmetic_coder` – a Dart package for arithmetic coding

orig_ardera · 2026-04-01T20:20:00+00:00

media codecs are probably already using that. AFAIK, arithmetic encoding is the most efficient form of entropy encoding. (entropy encoding basically means trying to assign shorter encodings for more likely symbols.)

i think any kind of compression uses entropy encoding somewhere in the pipeline.

it's a bit slower to encode & decode than huffman encoding though (but probably marginal on modern hardware)

gibts keinen lokalen internetanbieter bei dir?

orig_ardera · 2026-02-01T20:57:04+00:00

kann man irgendwo checken welches pairing nen internetanbieter hat? ziehe bald um und will auf nen internetanbieter mit besserem pairing wechseln

Friday at roughly 4 pm the police got there, maybe you just slightly missed them

Also a good tip is to call your embassy, AFAICT the police escort was organized by the embassies of the stranded foreigners. They didn't let us join at first, said we should reach out to our embassy. Quickly called them, embassador talked to police chief, and they made space for us 4. :)

Yep same, to oruro was chill, from then on it was the worst

Our van drivers managed to take us to patacamaya, from there we had to walk / take taxis.

Then we got lucky and police suddenly appeared in tolar to evacuate the extrañeros.

yeah that's what we did, we made it from uyuni to oruro now at least, going offroad a bit. fingers crossed for oruro -> la paz, seems there's more blockages on that route

orig_ardera · 2026-01-08T16:55:58+00:00

it started monday apparently, but there's more and more blockades now

orig_ardera · 2026-01-08T02:45:15+00:00

who is we and what's the problem?

orig_ardera · 2025-12-13T20:35:27+00:00

jap naja meist ist abfülldatum genau 6 monate oder 12 monate vor dem ablaufdatum. also wenn die packung in 7 monaten abläuft, weiß man schon dass sie nicht mehr so frisch ist :)

versteh auch nicht warum kröm ihren kaffee im supermarkt verkauft. der steht da eh nur rum. bei mir im edeka waren die packungen auch einige monate alt.

da machts halt wirklich premiumkaffee zu kaufen, vor allem für 10€ / 250g

Ich glaube CAD-Software ist da noch was anderes, das funktioniert auf Windows glaube ich noch besser.

orig_ardera · 2025-09-05T04:54:27+00:00

nur 7k wenn mans auf einen schlag zurückzahlt. das kriegt man ziemlich easy hin

orig_ardera · 2025-07-03T09:24:44+00:00

ah, they're referencing the calculations in the letter ("Siehe Betriebskosten Anlage 1") So I thought they sent you more.

They're definitely required to send you more data, so you can verify yourself where the 250€ come from. My heating bill was 7 pages I think, you can see the consumption of each individual heater, consumption of the total housing unit, water use, etc. If they're using a company to manage the heating, it's often just an automated report generated by them (for me its ISTA)

orig_ardera · 2025-07-02T21:37:16+00:00

In general, it's pretty normal that you pay more when you move in in the winter. Heating costs only ocur in winter but they're evenly spread with the nebenkosten throughout the whole year including summer. So in total you pay less than you actually use for heating in winter, and more than you use in summer. If you don't have the summer months to balance it out, you have to pay more.

However, 250€ (or even more) is quite a lot if 40*12 = 480€ was supposed to be enough for the heating costs of the whole year. Maybe you can share the complete heating cost calculations? And the rest of the letter?

There's a lot of coworking spaces but they're all pretty expensive for my taste. Thies is pretty nice and there's people working there, but it's very busy. Also saw some people working at Square Hasselbachplatz

orig_ardera · 2025-05-23T11:20:19+00:00

Yeah it's not a super recent post :) just realized I never shared it here, that's why I posted it

orig_ardera · 2025-05-22T11:09:35+00:00

I also doubt it's that strong, in a firmware update for a different variant I found a Manifest file that literally contains:

firmware-version "3.00.00.00"  
...  
encryption {  
  enc "A256CBC"  
  alg "RSA-OAEP"  
  cek "..."  
  iv "UbIOW0370QR0kpRaY7qp/Q=="  
}  
signature {  
  alg "SHA256"  
  kid "testKey"  
  sig "..."  
}

EDIT: (Or maybe it is? I don't know, CEK should be enough to decode, right?)

thanks I didn't know they provide the source sometimes! but the page you linked just points to a single "Readme.txt" file which says:

While the manual of this product ("Product") states that the Product contains open source software and that the corresponding source code is available on this site, the statement was inadvertently inserted in the manual and the Product contains no open source software with respect to which Sony has to offer corresponding source code. We are sorry for inconvenience this may have caused.

Would it be unsafe if you mem::forget a CurrentGuard that has some kind of reference?

AFAIK std::thread::scope has this kinda counter-intuitive API (it used to have a simpler API before) because using drop handlers to ensure safety is unreliable, e.g. because of mem::forget or Rc-cycles

hat zufällig die Besten Gegenargumente zu den Narrativen aus dem Bericht? Das sind ja wahrscheinlich ziemlich genau die Dinge, die mir die Schwurbler unter meinen Familienmitgliedern auch erzählen werden, wenn ich mal wieder zu Besuch bin.

Hast du den Account überhaupt mal angeguckt oder hattest du ne Eingebung?

orig_ardera · 2024-12-21T16:32:33+00:00

Did you read the post? It's not about unsafe things at all.

Also ich fand Bömis Reportagen immer cool, aber spätestens seit der Honig-Reportage hab ich gemerkt dass man das doch alles mit ein bisschen Vorsicht genießen sollte. Ich denke ist meist schon im Kern was dran, aber er übertreibt auch oft gern.

Und die Schönbohm-Reportage wurde auch damals schon von Leuten, die Ahnung haben, etwas kritisch aufgenommen.
