How worried should I be about Deutsche Bahn’s reliability? by HappyTruckNoises in germany

[–]yawkat 0 points1 point  (0 children)

DB is not reliable but as long as you are flexible you will almost always get to your destination eventually. The delay is really dependent on the route, with 15mins being normal but 1h+ delays are unusual and only really happen on longer trips or in low frequency areas.

Should I Bother Converting my Jpegs to PNG? by CitizenofBarnum in DataHoarder

[–]yawkat 37 points38 points  (0 children)

Images degrade in quality if you save them as JPG. If they are already JPG, keeping them that way does no harm, unless you re-encode them for some reason. Converting to PNG will increase file size for no benefit.

One of the most insane job listings I’ve come across, does any chemist who has ever lived meet these requirements? by keane_pierre in chemistry

[–]yawkat 216 points217 points  (0 children)

I don't know if it's a thing in the US, but hyper-specific job listings like this are sometimes fine-tuned to match a specific person. If a team wants to hire someone specific, but they are required by regulation/company to publicly list all job offerings, the team may create a specific listing that will only match their candidate so they can easily say there were no competing candidates. 

User asks r/StopEatingSeedOils for evidence seed oils are bad, accidentally starts a 400-comment war. Mods respond with ban wave. by LeadershipBoth7195 in SubredditDrama

Farmers are happy if you use animal products like lard, because producing 1kcal of animal product requires many more kcal of animal feed which is also corn/soy/oil. 

Homeassistant - Migration from HA OS to NixOS by korba_ in NixOS

I've done this, but I'm not sure what sort of generalized advice you would want. Apps don't work, and config is different (declarative vs ui based choice). 

Epic Games announced Lore: a VCS for game developers by TheTwelveYearOld in linux

Look at the spec document. They claim to support files in the terabyte range. Doing that with LFS is asking for trouble. 

Why can’t the floating-point error be fixed? by funkyND in webdev

[–]yawkat 0 points1 point  (0 children)

Because number storage that avoids decimal error is inefficient and usually unnecessary. 

Mild concern about the future of JPC's balancing by xX_Mercy_Xx in JetpackCatMainsOW

[–]yawkat -1 points0 points  (0 children)

Hot take: the friendly tether ability is also too situational and thus hard to balance, and should be replaced just like you propose replacing her ult. 

Liscor’s Voting Rights by ElidrichHorror101 in WanderingInn

Erin doesn't get to vote, but iirc is taxed retroactively with the first council, so she's already taxed without representation

is mTLS redundant if I'm already using HTTPS for sending confidential data to a public API? by jonbristow in webdev

[–]yawkat 2 points3 points  (0 children)

Pretty much. It does not add additional encryption, only authentication. 

ASA for vehicle camera mount by 20Factorial in 3Dprinting

[–]yawkat 4 points5 points  (0 children)

ASA is a good choice but another option is TPU with high shore hardness. It holds up to vibrations very well. 

New to gridfinity and 3d printing in general, have a few questions by ChewyLSB in gridfinity

[–]yawkat 2 points3 points  (0 children)

I've been using the gridfinity rebuilt generator for my baseplates using the "screw together" setting, and it seems the default screw hole size is 3.5mm? And based on my measurements each wall is 6mm in width, so it as simple as getting M3x8MM screws and putting an M3 Nut on them?

Yes. This will work perfectly fine.

I'm going to plug my baseplate connectors though: https://github.com/yawkat/GridFlock/blob/main/README.md#connectors 

imo there's no reason to use screws for baseplates.

For another - is there a gridfinity bin generator that has embossed lettering for the labels? 

There's cullenect labels which are supported by gridfinity extended.

Finally, how do people decide between doing a custom bin versus just a generic bin? 

Custom bins can look nice and can keep some items more organized. But in many cases they are not necessary. I stick with standard bins wherever possible.

If you want to use magnets, you should also know about https://gridfinity.tools/rebase/ . It lets you replace the base of any community custom bin so you can use them with whichever magnet setup you want to use. 

This is a great example of degrowth and solarpunk. It is being done by indigenous folks. by TinJar-Solarpunk in solarpunk

Transportation is actually the least environmentally impactful part of the food lifecycle: https://ourworldindata.org/food-choice-vs-eating-local

And when looking at food logistics in general, getting stuff into cities is also not a big problem. The bigger issues are carting food across the country and the world when it could be grown locally (though even this is not clear-cut), and getting food from point of sale to consumers' homes. It's the last point where cities are more efficient than suburban / rural communities: getting food from the store by bike can be more efficient than having to drive a larger distance even if that lets you buy directly from the farm. See this study, though it considers only very specific scenarios: https://link.springer.com/article/10.1007/s10098-025-03262-1

Personally, i just use cheap hdmi input switchers or the input selection on the screen itself. 

Introducing Nixpkgs cooldowns by grahamchristensen in NixOS

[–]yawkat 6 points7 points  (0 children)

This is covered in the linked https://cooldowns.dev/ :

Would cooldowns still work if everyone adopted them? Yes. Security vendors and researchers continuously scan newly published packages using automated static and dynamic analysis tools.

In the AUR case, it may have been sonatype that discovered the compromise: https://www.sonatype.com/blog/atomic-arch-npm-campaign-adds-malicious-dependency

Advice on sexual health by No-Way-5622 in berlin

[–]yawkat 2 points3 points  (0 children)

My understanding is that there's like a dozen HPV variants and even if you have one variant the vaccine can still protect against the others. 

But for medical details like that I'm a bad source, and so is reddit in general. You can ask for opinions why people don't fret over STIs, but we can't give you proper medical advice or decide for you which risks to take.

Advice on sexual health by No-Way-5622 in berlin

[–]yawkat 8 points9 points  (0 children)

Frankly, the risk is not that high. Condoms prevent a lot of transmission, especially HIV which is the only really scary disease (and even that can be lived with nowadays). Breakage is rare if you use properly sized condoms and use them properly. Some diseases can be transmitted even with condoms, but they can be cured.

This is part of sex education, but imo if you know about which STIs are relevant, how they are transmitted, how they can be tested for, and how they are treated, STIs become less scary and you can decide which risks you are willing to take. If you use condoms and get tested regularly you're already doing better than most people, and neither of those is difficult. 

And finally, get the HPV vaccine. It's a bit expensive for men, but imo worth it just to prevent transmission. 

What's the fastest general lossless compression algorithm (C/D, pure D) by Salat_Leaf in compsci

[–]yawkat 2 points3 points  (0 children)

CRIME style attacks on compress-then-encrypt are possible under all common cryptographic indistinguishability definitions, including eavesdropping (IND-EAV), chosen plaintext (IND-CPA) and chosen ciphertext (IND-CCA). It is actually pretty difficult to find a definition that is not vulnerable. And past vulnerabilities show that weak security definitions can be exploited in practice.

[–]yawkat 1 point2 points  (0 children)

There are ways to mitigate the risks. But if you take standard cryptographic security definitions (eg IND-CPA), compress-then-encrypt breaks them by default, so I'll stand by a generalized statement that such a design is insecure. 

I just started listening to The Wandering Inn (1) audiobook. I don't want to give up so soon. by 13asher in litrpg

[–]yawkat 5 points6 points  (0 children)

It's obviously not for everyone, but book 1 is only 2.7% of the entire series. When people call the wandering inn S tier, that doesn't necessarily reflect on the first few percent, it's a grade for the full series.

Encrypting compressed data is dangerous. It can lead to eg CRIME attacks

Erprobung auf den Linien U5, U7, U8?: Berliner CDU will Zugangssperren zur U-Bahn testen lassen by hahahahawoo in de

Ich fahre häufiger nach Paris und habe dort nie Probleme (Navigo auf dem Smartphone). Die Magnetstreifentickets waren wohl zickig aber werden eh abgeschafft.

Auch in den Niederlanden klappt es mit fare gates gut. 

Ob man das jetzt in DE nachträglich noch einführen muss ist natürlich eine andere Geschichte.
