This was a deliberate decision back in the 1980s and 1990s related to how to structure personnel. You'll likely recognize it as how software teams are siloed and the concept of "full stack" is kind of a misnomer.

The theory was basically that complex systems needed specialization for building and maintenance and that the US military could not afford or recruit the kind of people that could simultaneously run operations, do management AND troubleshoot.

In other words, military personnel are not seen as technical experts that focus on one thing for a decade, moreso that they are like project managers who have depth in one area from their first 5-6 years and then "broaden" out to fill in the management layer of the force beyond that.

There are exceptions to this of course, warrant officers and the like. However it's a tiny slice and given how massive the system is and how many sub-systems are involved - the management layer grows in the form of uniformed ranks while the technician layer grows in the contractor ranks because of how the force is structured.

The incentive for that contract force however is to keep the contract (and follow on) and the knowledge related to it, so they end up building in these kind of "nobody can touch this but us" requirements. Functionally you can see how this is a self fulfilling prophecy - we aren't recruting or structuting our force to have the capability to maintain systems because we have a contract force that does it.

To fix this a deliberate decision has to be made to change the force structure to build more technicians and unfortunately people like that don't want to take the pay and lifestyle cut so we just can't fill out the ranks.

I could go on all day, including how the defense industrial base as well as citizens balking at growing the size of the uniformed forces reinforce this system, but it's a pervasive problem across multiple vectors.
Seems like an old issue. I used to know a WWII British navy officer who complained how the Americans were so wasteful because they would get equipment replaced instead of repairing it themselves. I had assumed it was because their manufacturing capability was greater/cheaper but maybe it was this kind of war profiteering (is that the correct term?).
Donald Knuth once wrote a paper with some source code.

He warned his readers about just copying the code, perhaps half jokingly.

He said, approximately, "this code has been proven correct, but not tested."

I agree with this 100%. Learning to use tools beyond what you use at work makes you a better programmer, which in turn makes work easier.
They need to build these refineries[0] for fuel creation on Mars, so it's very likely they will build and use them at Starbase on Earth to test and gain long-term maintenance experience.

The happy consequence is relatively low net-carbon emissions.

They do, and they let you install your own OS.

Really good points!

For #1, I agree that section can be a bit difficult for new users to grasp. It's laid out the way it is so that later you can simply click and drag to re-prioritize goals and see the effects, but I'll think about how to communicate the purpose of that section better from the beginning.

For #2, yeah the concept of showing debt on top of everything else may be a bit... unconventional haha. That's where switching the plot to the net worth one can help somewhat if you want the chart to clearly show total net worth. In the stacked view, changing house value to equity is an interesting thought, though I think that still leaves it an open question how the chart should account for the other kinds of debt one might have.

For #3, yes definitely. Identifying warning scenarios and clearly marking those is a good feature idea.
> Consider this is HN

Consider this is the gaming community which already owns PCs and consoles that either outperform or have larger, richer libraries than this thing.

> ... which competed with the Gameboy

You mean the more successful, lighter competitor with a better library?

> First, this is much larger than you might expect.

Really not that big considering the demands of actual gamers. Especially compared to already established platforms

GitHub's Terms of Service doesn't override licensing terms.
I think they've done fine with VR hardware, except for that market still being pretty small/niche in general. Oculus probably has a more well known brand, but the Valve VR hardware is - I think - pretty much best in class, and I think anyone would choose Valve over Facebook as a source of VR games. HL Alyx was well-received as well. But VR is still pretty niche.

Steam itself is their biggest success of course, though that is not hardware. I do believe Steam took good perseverance and good execution to achieve the success that it's seen. (Re: perseverance, remember that when Steam first came out, people really hated the idea!)
Most tools were modified to use Spec framework so they can use the native look (using GTK) as well as the non-native one. (plus, in future, Web and Console backends). This transition should be finished in the next release.
Micro SD is an order of magnitude slower than the NVMe option, though.

They will just use an SD card. Yeah it's not as fast as SSD but it's the low end device.
Gamers be like: "btw I use Arch."
But why would you want the latest upgrade rather then a stable platform to build a console?

If you upgrade often and you break stuff people will scream at you, so you need extensive testing of 3rd party games before you release an update of your os, which will naturally limit you anyway.
I realize you're probably a true believer, but for a lot of people there is no truth. The bible is written by people, translated by people, and interpreted by people. I don't believe in your religion or any other, but even assuming it's true, the fidelity of the text is poor at best.
You raise a few good points. Falcon 9 launches could be 30% cheaper if fully reusable but that only reduces a launch cost down to $25M.

I am skeptical of the claim that they will just be able to refuel and go. Every reusable space vehicle has had that goal and always cost more than expected to refurbish for the next launch. Yes, we may get there eventually but not in the next few decades, the risks of a catastrophic component failure are too high to do no refurbishment.

The starship and super heavy are certainly cheaper to construct but that has more to do with fabrication techniques than the material cost.

Methane is less dense than kerosene so needs larger tanks but it does have more energy per unit mass. The overheads of using cryogenic fuel are reduced on a larger rocket but the performance gain is probably only 10% or so.

I am not aware of any significant insulation between tanks on the Falcon 9 and it certainly isn't a major cost factor.
It's not like the history of logistics and repair when it comes to war was solved / squeaky clean to begin with.

Not to hand wave the actual problem but this topic isn't exactly new.

Also just not knowing if another given nation does or doesn't have a problem sometimes is more about how open they are about it ...

> Still, it's sad that Smalltalk & company haven't received the VM optimization attention that JS has.

Well...if you consider that the heritage of V8 in Node.js kind of goes back to StrongTalk, I'd say Smalltalk has received more of it than perhaps many people think. Unfortunately StrongTalk didn't really succeed on the market for the same reasons as many other Smalltalk implementations - proprietary nature and exclusivity doesn't really help you in the long run against worse-but-cheaper-and-more-accessible solutions.
Good point, I hadn't thought of that. The last time I played anything on Nintendo hardware was Mario Kart on a Nintendo64 (which was awesome!), so I missed quite a bit of evolution there.

Valve could try to create games that are more appealing to the typical Nintendo enthusiast, but I suspect the respective cultures are too different.
I remember buying an FZ-1 when they were being blown out (like most of my synths at the time). It sounded really good and was relatively easy to do simple sampling, but the UI especially on that postage stamp sized grey LCD made it hard to do much else. I actually had a lot more fun with my stone age Ensoniq Mirage. That whole era was one of good sounding ROMplers with nearly impenetrable software (I'm especially remembering my K1000s).
Would’ve been an instant win for me if I could do a Switch-style hookup to the TV. Without that, it’s just another limited mobile gaming console.
Because it is...? People move to different states all the time just to change jobs.

If you disagree with the way that your state operates so strongly that you can't stand it anymore...moving becomes a pretty easy decision.
I hope they put some effort into anticheat on Linux for their own games. Team Fortress 2 has been barely playable for the past year because of cheaters running bots using widely available software which Valve seemingly can’t detect on Linux.
You're probably right. And assuming you are, then I think maybe the core problem may be that academics even tolerate the petty undercutting of reputation based not on the merit of the big ideas, but rather minor flaws in the proofs of concept.

There's also a problem in allowing papers to get away with making arbitrary claims that are by definition irreproducible. Every paper always includes some section about how many gates a design took up and how fast it ran -- but there aren't entirely consistent standards for reporting these things; it's often too easy to hide significant setup costs when running benchmarks.

This leads to an incentive to overstate results, because without any threat of checks it would be disadvantageous to not cherry-pick the absolute best numbers you could get through a peer review committee.

I get the desire to escape petty criticism: but it seems like a weak argument against the myriad of reproducibility and integrity hazards such a lack of transparency begets, especially for a line of work that ostensibly distinguishes itself on high standards for merit and integrity.

It also would have been nice to just receive a polite response of the form of "sorry, I don't support this anymore, I've moved on..." from anyone I had reached out to. Before starting on this project, I emailed four or five groups that had all published various papers on Curve25519 accelerators hoping to get even a broken non-compiling repo that could have helped me sanity-check my understanding of the thornier concepts presented in the papers.

Not even a single response...hence the motivation to write up notes and share them. Seems a waste of funding to have so many implementations, but no way to actually use any of them...
That's like saying a game competes with GitHub because it contains source code.
Now this is actually pretty good. A sad comment on the state of affairs maybe, but quite amusing nonetheless.
Methane burns with oxygen to carbon dioxide and water. CH4+2O2->CO2 + H2O
Indeed, I'm using the fact that it's ludicrous to make the case that a $2M starship launch is equally ludicrous.
> In time of full scale war (or potentially whenever they want) the gov't can do whatever they want including changing the deal. This of course doesn't obviate your claims, because in case of all out war all the broken equipment contractors have been milking might cause huge problems.

I mean, assuming the soldiers have the tools and training to do it. If they don't, changing the terms of the deal doesn't matter much, since the soldiers won't be able to repair when they need to.
Apple had a solution to this problem years ago but made the very very very stupid decision of removing 3D Touch from recent iPhone models.

On phones with the feature, you can use your left thumb to walk, right thumb to aim, and 3D touch (press down hard on the screen to shoot). I know at least call of duty mobile supports it, and when I tried it out it felt revolutionary.

But rather than add new input methods, they’re removing them at the same time they’re trying to push harder into mobile gaming (with Apple Arcade).

It’s baffling as an outsider to see such obviously bad/stupid decisions like that from such a massive company.
If the Steam Deck is successful I imagine that will give less demanding titles that will be much closer to 8 hours battery lifetime a nice boost.

I'm suspect games like Among Us, Mindustry, Poly Bridge or Human Resource Machine or Life is Strange will boast a good battery runtime (just scrolling through my steam library).

USB-C charging also opens the door to some quite large battery packs (Dells sells a 65Wh power bank)

An excessively negative take, why?

1.5 pounds is what the 2010 iPad weighed, people managed to use it just fine.

As for visual appeal, who knows? PC gamer aesthetics seem to be oriented around dotting your CPU case with the most gauche RGB lights Amazon dropshippers have to offer. At least this is more toned down than say, a comparable Alienware product.
An awful lot of indie games release on PC and Switch nowadays, really the switch supplanted xbox and ps in terms of where a lot of indie games sell.

So certainly a lot of switch owners are playing indie games that they could be playing on this device with better performance.
Its also possible that after pitching it to them, Delta explored the competitive solutions for the same issue and bid it out to some other vendor, perhaps their dispatch software vendor or one who could integrate with that software.

You can ridicule Stoicism as "self-tyrrany" as Nietzsche did, but it's hard to quibble with its effectiveness in a situation where your control over your life really is minimal. The first books I had Amazon ship to an old friend when he was sent to prison for a couple of years were the _Enchiridion_ and Marcus Aurelius' _Meditiations_, and he credits them with equipping him with the philosophical and psychological tools to survive there.
When individuals are wealthy enough to pay a state's National Guard to deploy on the border, then they are too wealthy for a healthy democracy.

Facebook's Alternative Facts
Sure when you're talking about older games. But for newer games I'd say support for XInput is pretty consistent, and resolution support is usually OK too.
>If I studied a bunch of different open-source projects, learned techniques from them, and implemented them in my own projects, is that a derivative work? Probably not.

That's pretty unclear actually. If it's quite close to the original work, it is derivative. Even though you have probably been "trained" on quite a few different codebases over the years. Hence the existence of clean-room implementations, wherein the people building a new implementation have never seen the original.

Also, given that code that has been passed through a biological network (ie, brain) can constitute infringement, it seems obvious that code passed through a mechanical one could too. Maybe not in every case, but it certainly seems plausible.
> The Cell CPU in the Playstation. (Not enough memory per CPU to do much locally, and slow access to main memory. Tied up the entire staff of Sony Computer Entertainment America for years trying to figure out a way to make it useful.)

At least towards EOL, developers did figure out what to use it for, like using the massive readback performance on the SRAM for tiled deferred shading:

That's great, but "Nintendo not being about power" doesn't change the fact that many of my 40$+ Switch games barely run on the device and run at such low resolutions that it feel like looking through an oily glass.

Seems like something is very wrong with either Switch hardware performance or Nintendo quality control.
What does Valve have to backport? Surely games aren’t targeting super new libraries? (I’d expect Valve themselves to be the ones deciding what versions are targeted.)
Boy I hope they park them in orbit on the last launch and use them to build space habitats.
Then, assuming they all agree with you, can you link to one of those people/analyses who quote the racist parts of the memo?

"Sure, drugs is being sold to kids. For recreational (weekend) use and not full-filling some addiction. So does that make it a drug-problem? From my point of view most kids know exactly what they are doing."

From my point of view, very few people know what they are doing, let alone children. Honestly you are ridiculous.
Methane is a greenhouse gas, until you burn it. Then it's water and CO2.

The wikipedia article on methane says something like "There is little incentive to produce methane industrially". Basically, we have too much of it already, from fracking, from livestock, from all sorts of places.

Giving it to SpaceX to burn as rocket fuel makes it a less potent greenhouse gas.
Very basically this is the bi-directional formula:

Methane + O2 <=> CO2 + H2O + energy
Is GitHub making sure that license terms are being met when they train Copilot on hosted code? Because anyone can rehost code that they don't have the rights to, and it seems like GitHub will still train Copilot on it.
>The easiest and least problematic is to add friction, which in my fantasies would be to ban sites like Facebook and Twitter outright that provide too-easy access to ready-made audiences of millions. They're basically like handing out loaded guns to a class of first graders playing on a playground. Guns are fine and shouldn't be monopolized by one group or another, but they should also not be in the hands of untrained first graders on playgrounds.

Friction, or training? In the example of guns, there are SCREENING (not exactly the same as friction) and education/training that many seem to agree are a good solution. Could the same be applied to social media?

>A somewhat less radical form would be to kneecap the ability to share widely on social media sites: no public posts, sharing limited to direct connections (and a cap the number of those to 1000 or something), no features to easily re-share a post outside of its initial audience, get rid of groups, kick out organizations, etc.

This is again just letting Facebook dictate the solution - not that much different than the unilateral censorship they do.

>Bring back classic web forums for communities, and push people who want to build an audience back to blogs and personal websites.

Seems like this is happening today, and might be a good approach.
It's using a custom AMD APU, so I estimate it would be probably a bit weaker than Ryzen 7 5700G's integrated GPU (1.6 TFLOPS advertised vs 2.1 TFLOPs for 5700G).

Though the performance may get a lot worse if you're using it on battery power, or the device gets hot enough to get throttled.
For me college was the most stressful. High school was a breeze then all the small anxieties I had in high school just got amplified in university. A lot of it was fear of failure. In highschool you get a bad grade it goes in your nebulous "permanent record"

I went to an expensive out of state school and it just felt like the stakes were so much higher. A bad exam could lead to a low GPA, loss of scholarship, being pushed out a program or major, academic probation, etc.

In the working world I met so many successful people who failed at some point, have a criminal record, poor credit scores, bad employment records, etc. and it never seems to go as bad as it's portrayed.

Even creditors don't scare me anymore. I just tell em to fuck off, verify the debt, and never contact me by phone ever again. A younger me would freak out about my credit score if a collector called. Because I thought that's what mature adults worry about.
In a mobile device, it's not necessarily about the power delivered over the Vbus wire, but about the energy required for the transceiver and serdes logic in the controller. USB 1.0 "low speed" had a clock of 1.5 MHz, and USB 1.1 "full speed" is clocked at 12 MHz. You can communicate at that frequency with a microcontroller on an ancient process node on a coin cell. USB 2.0 "high speed" runs at 480 MHz. Running a processor at that frequency requires significantly more power, but is not too egregious.

USB 3 is clocked at 5 GHz, which requires more power still. Just having a transceiver capable of that frequency enabled will draw a significant load from a battery, regardless of whether you're using the bus for power delivery.
