Fertilizer requires the production of ammonia NH4. That is one nitrogen bonded to 4 hydrogens. The nitrogen can come from the air but the hydrogen has to come from some other compound.
>So is prison meant to reform or punish?

As downtown SF is currently demonstrating, prison is also designed to separate. If you let violent criminals and the mentally ill sleep on the street and steal at will, it makes life much worse for everyone else than it makes life better for them.

I mean... Yes? Spamming and calling people is what Datadog is known for; you might as well ask if people have been shaken down by Oracle, seen Google discontinue a product, or had Microsoft force their laptop to reboot at an inconvenient time. That's their whole thing.

Indeed. Here's a case I happened across recently that go almost no media attention[1]. Got almost no media attention. Guy that stalked and assaulted a woman was released early on parole. Proceeds to stalk woman again, is arrested, prosecutors don't press charges. Assaults the woman again, is arrested again, prosecutors don't press charges. Eventually, the man kills the woman.

There are dangerous individuals that need to be removed from society, and when they're not, they hurt and kill those around them. If there is a more efficient and effective way to do this, that would be great. But it's hard to have this discussion when people pretend these things aren't important functions that need to be addressed in some way.

> It's really not as hard as you think to run ethernet, often it can be run along existing HVAC ducting.

As someone who had replaced a powerline adapter after a few days of trying and went with hard wired ethernet..It depends on your house layout.

I have an open-concept home which is also missing a room to create really high ceilings in the dining room.

To run an ethernet line from the upstairs to the basement i had to use 30 feet of string and tie a bolt to it. I then did some "fishing" in the cold air return to eventually reach the basement.

It can be done, but can also be very challenging.

Wifi is getting better and better as time goes on. These "mesh" wifi systems are amazing. I've tried many wifi routers before but due to the size and layout of the house they always left really bad dead spots.

We now use NETGEAR's Orbi system , and it provides high-speed access all over the house including the deck.
Tell HN: If upgrading bare metal Alpline Linux to LTS 5.15.76
This may only apply to a small subset of people here but if anyone uses Alpine on bare metal and upgrades the kernel to 5.15.76, it may hang at 18 to 24%. If it does, just control-c and remove the /boot/.apk* files and undo any custom hardening that disables unused kernel modules. This specific kernel is attempting to talk to a module, I suspect related to the backlight quirks [1] being added not related to 6.1. I have not dug deep enough into this to know the exact communication that is timing out and honestly I am too lazy to do that.

Just move your scripts and/or modprobe.d custom blacklist files out of the way, reboot, then upgrade the kernel, then move your hardening back in place and reboot again.

Again, this only applies to people that disable unused modules and only on bare metal. I do this on my router/firewall to keep the memory footprint smaller and attack surface smaller. I'm odd like that.

I have not run into this on any of my VM's and only on 2 bare metal machines.

Dumb question: why can't the hydrogen also come from the water vapor in the air?
It at least 50% doesn't matter if the undesirable actions are the result of honest ignorance. They are still undesirable, and he is now being informed. I don't think there was really any excuse in the first place but definitely now there is none at all, and the non-response validates exactly the open letter's complaints.

That’s not an attack. I think they are just trying to make the point that once you enter unsafe rust, you can use any unsafe language since the biggest benefit of rust is gone.

Unsafe rust is not used often, they never argued that.

I admit I don’t get the obsession with inequality when the absolute numbers are so high. It feels like a generation is treating envy as a virtue rather than a vice.
The latter is the problem. Half the people in the building are old, the other half of them are happy with the way it is - I'm the only IT guy. Might be possible to pull fiber through the conduits, but not sure if the Mnet FTTB box can actually give me fiber - I think it's a miniature DSLAM only.
You need a lot of solar to charge a vehicle but it is attainable.

You'd be better off with something like a M35A2 with the multi-fuel engine for actual apocalypse, because that thing can burn damn near anything you can find (you could run it for years on engine oil drained from mad-max style hulks). Someone may have even modified one to run on LPG also.
For anyone that liked “Blade Runner”, it’s fascinating to go back and read PKD’s “Do Androids Dream Of Electric Sheep”, which Blade Runner was based on. You can see the threads of similarity but it’s a way more surreal paranoid bad-acid-trip vibe.

If it's simple, why practically no one is doing it?

Last I heard, 99% of all H2 was produced out of methane. Perhaps it's a bit better now?
That would be highly endothermic. The energy needed to separate the hydrogen from the water has to come from somewhere. If you meant "why can't we electrolyse that water to get the hydrogen", well yes of course that could be done, and that's what's being talked about (using water from some other source, though; why from the air?) But the water doesn't just decompose on its own.
Then just make a cooperative organization. There are legal means for doing so in most jurisdictions. There’s absolutely no need to use a term that makes no sense without cryptoscams and hackable "smart" contracts.
You can just break apart water with very small tiny little hammers.

Finding the miniature dwarfs to do this is the tricky part.
Lol maybe I got your meaning!

By saying 'better', I'm not actually 'willing' to become better. In fact, I enjoy drawing even if the outcomes are 'bad'.

The hard part is, when I want to draw something 'concrete', I can't... For example, a story between a boy and a girl - The only thing I can do is to draw two sticks in order to make them consistent frame by frame XD.

So yes, I have to admit that I still want to share my creations with others, and without being better I can hardly do so... I think artists like Picasso are at another level, because they might treat art as their whole life, and might have the ability to focus and only focus on their own arts.

And me, as a normal person, will still need some compliment XD.

Over time I ended up with 21, 35, and 90mm as my go-to lenses. I used the 35 for many years now, which includes landscape pictures. With that said, I also use 90mm for that, because landscape pretty much covers the whole focal length spectrum, not just wide angle. 50mm is only stuffed into the bag for when I don't have to optimize for weight and it makes sense to have it around (portraits in tighter spaces).

In return, 50mm is usually cheaper than even 35mm options. On APS-C cameras this ends up being 75..80mm, which is already in the realm of portrait lenses, i.e. somewhat more restricted in its use than on FF bodies.

Deterrence doesn't only mean to discourage the perpetrator from recommitting the act, it means to deter the public at large getting doing so, for fear of punishment. So in the event of an accident caused by willful negligence, tyou would want to discourage others from being similarly negligent. For example, someone texting while driving who runs an intersection and causes a fatality. One reason to punish them is to impress upon others in your community to show care and awareness while driving.

I'm not endorsing this practice, just stating how I think deterrence is alleged to work.
Huh, interesting. The Panavia Tornado was a swing-wing plane from a similar vintage and did have pivoting wing-mounted pylons. Tradeoffs abound in aviation though, of course.
Where does that refund money come from though?
More F-14s were destroyed (which OK: in conjunction with the crappy engine) because of this design than in combat.

The AIM-54's never lived up to their name as an air to air missle, since it was meant to shoot down bombers, which never flew (and you know: thankfully never flew). Though they tried against fighters - that wasn't very successfully (except for Iran?).

One wonders if a computer system like what's in the F35 could have worked in the F14 to mitigate the problem with engine failure - of course: if one could go back in time 30+ years to install it.

Good point on the variable swept wings not allowing hard points, didn't think about that. The F111 did allow for ordinances on the wings and they did it in the method you've described (tho much larger plane)

Perhaps the greatest achievement for the F14 was selling it to Iran, which had a real hard time keeping them in the air due to flight costs. Kinda sold them a lemon then cut off diplomatic ties. No one else wanted the plane!
Hydrogen is needed for the Haber-Bosch process for making ammonia. For steel making, hydrogen would be used for reduction of iron ores to iron metal (currently, most of that is done with coke).

There's also a large market for using hydrogen to upgrade petroleum (hydrodesulfurization), but that market continuing to exist presumes some way of dealing with the CO2. Direct air capture, perhaps. There could also be markets developed to make synfuels from CO2 and hydrogen, or using hydrogen to upgrade biomass to get more fuel (hydrodeoxygenation).

There are various smaller markets using hydrogen. For example, making one of the precursors to polyurethane involves hydrogen as a reagent, as does manufacture of hydrogen peroxide.

Yes, ffmpeg is one hell of a library and documentation doesn't make things easier. You have to ask a lot of questions to understand the low level details, and also have to answer them yourself by doing experiments.

For the point about packet freeing, i think ``av_packet_unref`` is supposed to de-reference the ``encoded video/audio`` data being read in the RAM, so that internal ffmpeg code can deallocate it. It has to be called for every ``av_read_frame``. ``av_packet_free`` is supposed to release the generic ``packet`` object/struct allocated by ``av_packet_alloc``.
I learnt this while making a simple video player based on ffmpeg library.
Agree 100%. I shoot on an xt3 and cannot believe the consistent sharp and clear images through the Fuji glass. Also the kit lens is fantastic, only thing I'd love is if it could reach a bit farther. I'm sure there is an upgrade out there for and arm and a leg...

I have some old glass for my Pentax SP1000 which I was able to adapt to shoot on the new mirrorless. Some of the bookeh really is magical on those Super Takumar lenses. The crop is a bit of a mess, but photos are nice.
Yes.

I have seen false conviction estimates ranging from 1 to 5 percent. All systems which involve any kind of classification will have a non-zero false positive rate. Does that mean we should do away with them? Of course not. We should simply seek to improve systems with better and better processes, while accepting that we might approach but never achieve zero false positives.

What alternative would you propose? Doing away with criminal justice? Do you think murderers and rapists should be allowed to roam free? How about drug traffickers who knowingly distribute life destroying substances in their communities?

Think of someone you really love. Maybe its your child, your parents, your partner, or a friend. Now imagine the pain and fear they would feel as they are murdered. What would they think and feel as they are choked to death? Or bludgeoned? The sheer terror. The pain. The senselessness of their life ending. Imagine that you find their corpse. Imagine the pain and horror you would experience. The hole in your heart. Really try to visualize this scenario. To feel it emotionally and with your senses.

Now imagine the perpetrator going unpunished. Walking free. Or getting put on some cushy rehabilitation program to better their life. Does that seem right? Does it seem just? Does it seem fair?

In my opinion, this discussion is way too academic, abstract, and one-sided. How about we focus on victims and their survivors?

What reason did the cops give you for not doing anything? Was this in SF?
Currently the options seem to be prison or Congress.

There are a lot of naive takes in this thread. Prison is objectively and disproportionately racist and classist. It's not so much about deterring crime as about terrorising and brutalising certain demographics.

For the winners to feel better about themselves, the losers have to lose hard. It's essentially just sadism.

This has nothing at all to do with preventing criminality, as the penal systems in other countries - notably Scandinavia - have proved.
The F-22 is an air dominance fighter. It's primary objective is air superiority. F-35 on the other hand is a versatile multirole aircraft which has been adapted to 3 variants for air force, navy and the marines.

The F-35 trades a slightly higher radar visibility (vis a vis F22) with a very modular software & hardware architecture & networked combat assistance. Its avionics is much more easily upgradeable & mostly written in a C++ dialect to best of my knowledge. F-22 on the other hand is absolutely the best in class on stealth & maneuverability - but the tech it is built on, will be of 90s always (sadly). Its avionics & controls were coded in Ada on i960MX architecture (CPU clock ~90MHz) which is no longer maintained.

Between the two, F-22 is a marvelous bird still, and still outclasses F-35 in air dominance roles. Its capabilities can strike fear to even well-equipped combat adversaries. In an anecdote that I was told by an US airman friend, Pakistan AF had scrambled F-16s during the OBL's Abbotabad raid, but the sortie was pushed to flying the perimeters of the city when a F-22 pair switched on their radar beacons temporarily to ping their presence (& as a obvious warning). Apparently they were overflying at reasonably high altitude having taken off from Qatar or KSA on special close air support mission. Their stealthy presence & perceived capabilities from this incident speaks volumes.

Edit: The hardware is Intel i960MX. I mistakenly remembered it as IBM Power architecture.

Edit2: Aviation Intel also surmised that F-22s were possibly in the theater

You can, but doing so with renewable power would be under the rubric of "solving green hydrogen for industrial processes". In practice it's probably just easier to use renewably powered electrolysis to separate hydrogen and oxygen atoms from liquid water rather than try and use some chemical process to pull them out of the air.

Can you cite a source? Every generation for the last 200 years has felt this way, and I was taught from an econ degree years ago that historic averages turned out to be ~1.2 jobs created for every job lost to automation. Economies also tends to be self balancing which further lends credance to the idea that it’s really hard not have an employed work force. I think the bigger problem isn’t automation, it’s the way we treat capex vs opex in corporate accounting. We’d go a long way to make paying someone more tax beneficial than to go the ludite route.

(I also don’t mean to downplay the pain if displacement from automation, it’s a very real problem and a reason I’m a big fan of social safety nets)

There's asset price inflation, productivity growth, technological growth, and population growth.

I'm not sure why anyone thinks we need more people.

Humans make up 34% of all land biomass.

There are physical limits to technological growth. We're already getting close to the physical limits for how good a lot of things can get. Short of living in a fairytale, I'm not sure what people are hoping for.

Productivity growth is predominately going to come from technological growth. However, much of the world is ridiculously under-invested in. We have generations of growth left here. Why do we need more people when ~70% of the world is ridiculously under-invested in?

Asset price appreciation is good if you own assets - bad of you want to buy them. In an ideal world, I think assets would be valued based on some kind of sense - not whatever central banks decide.
