why do i focus on gaza, when there are other genocides happening? because it’s the one we pay for. it’s the one we can most easily stop.

why do i seemingly ignore antisemitism? because it’s a given. i don’t have to prove it to anyone here. we already know. we already oppose it.

do i support hamas (whatever that means)? hell no.

do i support israel’s right to exist?

@Petr90 @bycx @sesivany Elektricky pohon je cistsi... pokud se elektrina nevyrabi z uhli.

Ale me zajimalo jak je to s tou ucinnosti... Dle robota by ten sestitakt vyuzil jen 40% energie z paliva, coz mi prijde jako maly problem :-):

When burning gasoline, how much energy comes from H -> H20 and how much from C -> CO2?


ChatGPT said:

Thought for 50s
Short answer (using gasoline ≈ octane, C₈H₁₈):

About 41% of the fuel’s energy comes from H → H₂O

About 59% comes from C → CO₂

@sesivany @bycx Tak ... vypada to celkem zajimave. Jen uplne nechapu, jak to bude s ucinnosti? Cast energie se ziskava spalovanim toho uhliku, ne?

@dos Ok, so after a bit of fight, I got it to work. As usual, problem was elsewhere than I was looking: gl_init(), not shader.

@lkundrak Dekuju, mam tu X61t kde vyteklo lepidlo pod digitizerem, a snazim se s tim neco udelat.

Nevim, varovani je ze spatne skladovana IPA je velmi nebezpecna vec, a 5litru IPA by mi nejspis vydrzelo na ... asi tak 700 let.

Jak se me chatgpt-5 pokusil zabit:

Pokud chcete čistit notebook, berte ideálně 99% IPA (rychle se odpaří, nezůstane povlak). \
Sprej je praktický, ale tekutina v lahvi je univerzálnější.

Mám Vám najít konkrétní odkaz na český e-shop, kde se dá IPA koupit v malém balení (třeba 100–250 \
ml), abyste nemusel kupovat litr?


You said:
Cena?


ChatGPT said:
Zde jsou orientační ceny isopropylalkoholu (IPA) ve vysoké čistotě (≥ 99 %) dostupného v České rep\
ublice v různých objemech a formách — vhodné při čištění lepkavé vrstvy z ThinkPad X61t:

...

Shrnutí podle objemu
Objem Orientační cena (vč. DPH)
100 ml ~60–86 Kč
0,5 l ~127 Kč
1 l ~100–280 Kč (nejčastěji kolem 189 Kč)
5 l ~500–700 Kč
20 l ~2 230 Kč (cca 111 Kč/l)

Doporučení pro vaše použití
Pro jednorázové čištění rámečku X61t bude nejpraktičtější menší balení (100 ml až 1 l).

...

Chcete-li mít zásobu pro více budoucích tabletů, 5 l balení je výhodné poměrem cena/objem (okolo 500–700 Kč)

---

Jo jo, koupit 5 litru IPA, skvely plan... Jak vyletet do povetri.

Izraelsky general se tak nejak priznava cil "50 mrtvych za kazdou obet Hamasu" a "je jedno ze to jsou deti". Oops. Na yt hledejte "Leaked： 83% of Gaza ＂Combatants＂ Were Really Civilians [VAAguynnCxU]". Slovo na "G" jeste ve videu nepadlo, asi kvuli algoritmum yt.

Czechs tortured a prisoner, and the president helped sweep it under the rug :-(.

For me, they are murderers — they don’t belong in the army and they shouldn’t be walking free.

Here are at least the first names of those (very probable) killers:

@Logical_Error Yes, if done right, that might be fairly interesting. (It may also be hard to do it right). :-)

@dos Well, deleting that line was simple. Replacing it seems to be more difficult. Plus img_attrs need to be modified to be RGB888, if I understand things correctly.
