korhojoa··on Run0, a systemd based alternative to sudo, announced
Now if then the commands run via some kind of privilege elevation mechanism would require pledges to be used, that would be awesome: https://news.ycombinator.com/item?id=38037075

"This needs root", okay. But you only get exactly what you need.

korhojoa··on The reckless policies that helped fill our streets with large cars
Conveniently forgetting that the SUV trend started due to a shitty workaround to fuel economy requirements. There are so many unnecessarily large cars around nowadays.
korhojoa··on PCIe 7.0 Draft 0.5 Spec: 512 GB/s over PCIe x16 On Track For 2025
This really depends on what you're playing.

I used to use a pc built in 2013 with the then latest-and-greatest, but it did really stop being viable in my games ~early 2022 when they had some updates and four haswell cores just weren't enough anymore. Upgraded to 12th gen intel at that time and quadrupled my fps. (Notably cpu-bound games)

Games that are less demanding can be fine, but if you're playing something where frames matter might be harder to play.

korhojoa··on The largest deep lake water cooling project just got bigger
We have a similar thing over here, and the cooling capacity is pretty useful. ( https://www.helen.fi/en/housing-companies/cooling-for-housin... ) As the summers have gotten hotter, this has gotten more common to have a somewhat stable temperature indoors.

Heat pumps allow shifting the temperature that's in the cooling and heating circuits, so you can extract (or add) more heat, making it more effective. This is used to cool data centers and heat homes/offices, so it also allows to move heat between places instead of always having to have a cold sink and a heat source.

Sure, there is electricity warming up the water, but earlier the energy that was used to cool a space was just discarded into the air, now it's gathered and put into the circuit to be useful elsewhere.

Not a gimmick, it saves _a lot_ of energy.

korhojoa··on Fisker lost track of millions of dollars in customer payments for months
These aren't browsers, so that doesn't apply. Their authorities are completely separate. Check out "White Paper of Charging Interface Initiative e. V." from Charins website. https://www.charin.global/media/pages/technology/plug-charge...
korhojoa··on Suspicious discontinuities (2020)
The usual solution is something like: for x units of excess past the set limit, remove y unit of subsidy/support.

Example: something costs 20 money, if you earn 100 money or below, then it is subsidized to cost only 10, where 10 money is a subsidy. For every 2 money you gain, 1 money in subsidy is removed.

If you earn 104 money, it will now cost 12.

The x and y values vary depending on what kind of things are subsidized, but this is a fairly simple way of doing it that doesn't punish you harshly for a small difference in earnings.

korhojoa··on Freenginx: Core Nginx developer announces fork
This already happened with the kernel console, no more scrollback. https://security.snyk.io/vuln/SNYK-UNMANAGED-TORVALDSLINUX-3...
korhojoa··on As solar capacity grows, duck curves are getting deeper in California
Not California, but in general terms this is not accurate. My local grid connection provider (the largest in the country), does not differentiate between 1x25A and 3x63A in cost. It's the same price.

That's a pretty big difference in available power for the same price. (5.8~43.5 kW)

korhojoa··on Beeper pulls the plug on iMessage in response to Apple banning users
I still have my pebble(s, actually, originals and time). I haven't yet found any smartwatch with as much of a community around it as it had (and still does, many years after the company was sold).

My (attempt at a) replacement is a withings scanwatch, but it doesn't do color or have apps. The pebble physical buttons are awesome for doing something when you're restricted from using your phone somehow. The two weeks of battery life was also amazing. Anybody know any smartwatches with two weeks or more of runtime on a charge?

korhojoa··on Ask HN: Are height adjustable desks worth it?
I gave in and found a reddit post that contains four-legged variants: https://www.reddit.com/r/StandingDesk/comments/z1wt4n/list_o...
korhojoa··on Ask HN: Are height adjustable desks worth it?
There are ones with more legs, but they are in a different price category altogether.
korhojoa··on The Orange Pi 5 Plus
I don't understand how hours run equates to your calculation unless it was always pulling 2,7 kW. Is this some 30 year old setup that doesn't have an inverter-driven compressor?

Also, wow your electricity is really cheap.

korhojoa··on What happens when you trigger a car's automated emergency stopping?
I keep having mine trigger from trying to park next to a snow bank. The system doesn't know that the snow isn't harmful and will stop me in a very sudden, jarring way.

This is on a MK7 Golf, so it's been around on a very common vehicle for well over 10 years.

korhojoa··on A supply chain attack on PyTorch
If they're pulling from master instead of from a known version, it could be changed to be malicious, and the next time it is fetched, the malicious version would be used instead. It's a vulnerability.
korhojoa··on A decade-old Steam bug
This was a great read. I wonder if the reason for the game client surprise crashing could be investigated the same way? Do the executable integrity checks run during runtime? What if one of those fails while it’s running, do you get a different disconnection message?

I feel like this should be rewarded in the same way as the GTA V takes forever to load-writeup. https://nee.lv/2021/02/28/How-I-cut-GTA-Online-loading-times...

korhojoa··on Gas utilities used tobacco tactics to avoid gas stove regulations
Sounds like they should be held responsible for environmental harm, perhaps part of their their restitution could be installing a bunch of renewable energy sources (kind of like dieselgate). Seems awfully dumb to let them not do anything about it, but doesn't seem like a valuable counterargument to stay with a energy method that directly contributes to poorer health.
korhojoa··on Gas utilities used tobacco tactics to avoid gas stove regulations
If somebody installs something that requires a fee and extra connection when building with something semi-permanent like house appliances, kind of makes me think there is some sort of kickback scheme for them to do so.

Having gas appliances where I live is seen as a liability, as you have yet another maintenance item, and it contributes negatively to indoor air, so you have to have much more care regarding air handling in your areas where it is used. (unsurprisingly, demand for gas and gas appliances has plummeted ever since Russia started with their fuckery so people have been converting in droves as well.)

korhojoa··on Gas utilities used tobacco tactics to avoid gas stove regulations
When it heats it faster, there is less loss into the environment before all of it gets up to the required temperature. Efficiency gains is _always_ the desired optimization when you look at what new energy policies are trying to do.
korhojoa··on Breakdown of faults by car brand: Tesla has replaced Dacia at the bottom
You should try asking it about the heated seats in cars that don't have then unlocked.
korhojoa··on Breakdown of faults by car brand: Tesla has replaced Dacia at the bottom
Do you have the basic media unit that doesn't do anything or what? Otherwise you can just google the instructions to update and unlock your unit's features for free. Most MIB2(.5) units can easily be hacked.
korhojoa··on Google Fiber - 20 Gig + Wi-Fi 7 will be available to select customers
This is the Swiss 25G provider, yes?

Lounea in Finland provides 40G. It'd be amazing to have it, but unfortunately they don't service my building. :(

korhojoa··on HashiCorp Vault forked into OpenBAO
Consider how happy this made me:

I wrote a PR to fix something in Vault, then nothing happened for a while, then I saw that hashicorp is changing their licensing, and soon after that, my fix was merged. My fix sat waiting until they changed their license, and then it was merged before I had time to consider if I wanted to contribute under that license.

(Incidentally, sentry also changed their license soon after I interacted with the project. Maybe it's me ruining the OSS world)

korhojoa··on Dieselgate, but for trains – some heavyweight hardware hacking
They've actually been modernized with newer power electronics and some of the soviet oversights have been addressed. They're still very reliable, and now somewhat more efficient.
korhojoa··on Dieselgate, but for trains – some heavyweight hardware hacking
Considering that the situation this was named after had _very_ specific timing, state and sensor values coded in a defeat device, I'd say that having the mapped the gps coordinates of your competitors im the firmware of your product is pretty damning.

Nevermind the poorly executed "if day => 21, month => 11, year => 2021", which was conveniently setting a failure which wasn't actually present.

It'a probably not that simple, but it's not that complicated either. If you make something engineered to fail without there being a failure present, that's clear malice.

Imagine buying a car, you own it until the warranty runs out and the the manufacturer's workshop moves (say there was a fire/flood/sinkhole/industrial disaster, and they had to) and the car would refuse to move since it's not being serviced at the official location anymore.

korhojoa··on Dieselgate, but for trains – some heavyweight hardware hacking
There wasn't just one manufactured failure, but multiple different ones. Refusing to help would also point towards intentional malice. Why would you sell a product, then refuse to assist, unless you've intentionally designed the product to fail so only you would know how to make it work again?
korhojoa··on "Heaving oscillators" use wave power to extend shipping range
There are a few things you can do with acceleration like that. I do the same thing with metro/trams/trains/buses when getting off. Slowing down gets you to the door almost for free.

On ships another interesting feeling is being on an elevator and then feeling the forces get smaller and larger while you're going in either direction.

korhojoa··on Voice-over-LTE: The Reason Why Your Phone May Soon Stop Working
I've luckily mostly been on unlimited data plans, so I don't know about it using up your data, but I guess it would? Your device is sending and receiving data. I don't think there's a distinction for externally made connections, otherwise vpn tunnels would have been really popular.

I did have an experience with my phone being suddenly used by random internet users. I had ampache running on my n900 (maemo/debian-based) and somebody found it on the internet and started streaming my music. :D I had a higher-than-normal amount of battery usage for a few days so I decided to see what's using it and discovered that my music was being played and downloaded.

korhojoa··on Learnings from fine-tuning LLM on my Telegram messages
Out of curiosity, what's your take on how to write "this item requires repair"?

"It needs repaired" is something I've seen, which to me is confusing, because it seems like "to be" is missing. When did "needs" run away from the words it's been associated with before?

korhojoa··on Apple's Pro Display XDR takes Thunderbolt 3 to its limit
That's not really the full story, when this is about displays. I currently have a display that requires Displayport 2.1 to get everything out of it, and with DSC and DP 1.4, I can get a "theoretical bitrate" that is higher than what they would normally allow. (Of course, this doesn't change what the link can do, it just allows you to do more with the same bandwidth) On thunderbolt 3 systems, the link is on HBR3, which with DSC allows 120hz, 10bit at 7680x2160. No DSC support limits the refresh to 60hz and 8bit (as then you won't have the higher rates available anyway, since DSC is mandatory with newer standards).

You can check https://tomverbeure.github.io/video_timings_calculator to see what is possible.

korhojoa··on Bidding error sees Finnish day-ahead power price tumble
Very few people get paid during this market anomaly. Most people have fixed rate contracts, and the few that do have variable rates, even fewer have ones where the negative price would be passed on to you.

Transmission cost and taxes will still be present, so this is more of a "hey it's going to be a societally good thing to go to the sauna today instead of tomorrow, consider it!" (Also, the saunas are definitely in use, don't worry, nobody's going to pass up the opportunity to say they went to the sauna for a good cause.)
