Thank you! This is the most important and most correct comment on this forum today.

Truly, it's amazing how many aerospace engineers hang out on HackerNews!\s So many assertions about what is right, what is wrong, and who is to blame. 99% of these assertions reflect a poor understanding of how commercial aviation fundamentally and functionally works.

Not only is your comment 100% correct, it also strikes at the heart of the problem. Diplomatically, the issue that exists today is a clash of the very different safety cultures that exist between aviation and telco (and by extension the FAA and the FCC.) Aviation will win, btw. The question, however, is at whose expense.

Btw, the root of all this can be traced back work the aviation industry had undertaken to create a standard for wireless safety critical avionics (a system and standard called WAIC.) It was about four years ago that the aviation industry tried to secure additional spectrum, was denied, and thus started researching how to use the existing 4.2-4.4ghz spectrum already dedicated to aviation. It was through this research that the industry discovered the inherent problems with radio altimeters and nearby spectrum interference.

The aviation industry petitioned the FCC during the notice of comment period for the C-band spectrum sale, sharing the research and the data which shows 5G interference could be a problem given how it was planned to be deployed in the US. T-Mobile did their own preliminary study in support of the aviation industry's findings, but the rest of the telco industry attacked the research done without providing their own alternative data. The FCC, under Ajit Pai, and with support of the telco's lobbying arm CTIA, then effectively politicized any additional technical assessment or study, leading to today's brouhaha. If you want to blame anyone, blame the FCC and their former chair, who btw, is already a favorite internet punching bag.

(Note that T-Mobile is the only carrier that did not purchase the spectrum, although it's not known whether this was due to T-Mobile's own supporting research.)
None of that changes what crypto is. Another property of good money is performing transactions in a few seconds and being accepted by local markets for goods and services.
Kuala Lumpur is waving at you. Some of the best beef-broth noodle meals I've had there were sitting on crates next to Jersey Kerb, which was between me and a 6 lane highway of chaos.
It's the right choice. Otherwise you're wasting power for no reason. The only reason not to use the GPU is driver bugs, usually on Linux, that cause it to use more energy than the CPU.
The more interesting statistic, to me, is that

> 25% of the institutions produced 71 to 86% of all tenure-track faculty

which means that the vast majority of PhDs who got their degrees from the other 75% of institutions never got on the tenure track.
> I've been yelled out by drivers for riding my bike through a bike lane that happened to be in the way of the turning lane. You just can't win if you're trying to cycle in the US.

Some people are jerks in every situation. I don't believe bicyclists stand out as victims, except the expectation that they ride in traffic and the consequences of colliding with a car.
> probably only 20% of trips in New York are conducted by car

I’d reckon it’s less than 20%, maybe even as low as 5%. The subway alone has a daily ridership of about 2 million, plus the massive amount of people who just walk or bike to the store, work, etc. I think it seems like more people are using cars than actually are due to their visibility, like you mention—they take up more space, they’re given more space, etc. It’s insane.

Thank you, those are great suggestions.

The ECU selection was primarily budget driven. I need to have a look at those VESC.

Battery selection was again budget driven. The also hat to have certain dimensions to fit inside the kit.
They aren't, because they are not operating within their mandated frequency bands.

If I made routers that flood the EM spectrum with random crap, even if their wifi 'worked' they wouldn't be fit for use, either.
if you lay out your virtual memory space correctly on a little endian machine you can use the denorm space (assuming you don't care about underflows) for the actual memory and have floats and the rest of your world coresident in 64 bits.
> The problem is that radio altimeters are pretty old, and their filtering technology is not great. So even though they are filtering the 3.7-3.98 GHz 5G band, it's not as effective as a modern RF system/filter would be.

and actually not only are they old but they are defective - they were designed to function with guard bands half the size that the FCC ended up giving them, and they still are running into interference. They are basically picking up way way way more than they were originally specced to, and that's suddenly a problem because somebody moved in next door.

also to my understanding it's specifically a problem with Boeing and other aircraft are much less affected. So we are also running into the "boeing has become a quasi-state enterprise that is too-big-to-fail and will be protected under all circumstances even when they do something obviously dangerous", like the MCAS system on the 737 MAX.

honestly I kind of feel like the real situation here is that Boeing needs to issue an airworthiness directive and have those altimeters replaced. If a wing broke at half the loading spec, we wouldn't hesitate to say that's faulty and should be replaced. But with guard bands twice as wide as initially specced these altimeters are still having problems? Get them out of the air until Boeing fixes them.

> The real concern should be the total lack of collaboration between the FAA and FCC. It's turning into a jurisdictional pissing contest.

they were collaborating a long time ago - but again, there is only so much you can do when it suddenly turns out that a 2x margin of safety from the design spec (which itself incorporated a margin of safety) is not nearly enough.

the spectrum was sold a long time ago. the airworthiness certificates were issued decades ago. At this point there is no solution possible that doesn't make somebody unhappy.

I lean towards the party that needs to be made unhappy being Boeing here - but that will make airlines very unhappy as well. Saying "no you can't use that spectrum" is an unconstitutional taking at this point, you auctioned it off for cash monies and that absolutely puts a legally enforceable price tag as a minimum bound - in practice the value is higher since business plans have been built on it. But there is no constitutional right to fly a defective aircraft, if the FAA grounds your plane because it's unsafe that's not a taking.

But that will have a massive impact on boeing, airlines, and the economy as a whole.
Rights don't depend on what you pay taxes for; those would be fees and services. Roads are generally considered a public good, a commons, not a service you pay for (beyond toll highways)
Lack of censorship is not a failure.
How can you write an entire article about how hiring is difficult in some field, and only mention salary in a short parenthetical with no concrete numbers? (“salaries have risen in some cities by as much as 10 percent”)
I own two expensive cars that get driven. So, I’m paying my share of fuel taxes and above average registration/property taxes. When the wear cyclists pit on roads becomes a problem, we can discuss mitigating it. But, we’re nowhere near that point.

Historically, streets were for walking. Walking in cities predates cars in cities by thousands of years.
Or you could have residential development tied in with infrastructure. You want to build a no-parking building? It needs to work with the existing infrastructure. Doesn’t work with it? You need to contribute to making the infrastructure work with the building. (Paying for cycling pathways, adding separate paths for pedestrians and cyclists, improving public transit, etc.)
Examples of nuance:

You buy a Widget. WidgetCorp says you may repair it or do whatever you want with it. However WidgetCorp will not sell you any parts, or any schematics. WidgetCorp sues any third parties that try to make their own replacement parts. WidgetCorp engineers added complexity into Widget solely to make it impossible or harder to repair Widget (anti tamper screws, DRM on batteries). WidgetCorp will refuse to repair the flux capacitor under warranty because you have a modified fusion drive, even though no causal link can be postulated between the two. WidgetCorp will cripple Widgets that have 3rd party parts via software updates.

All of the above regularly occur with the likes of Apple, John Deere, Dell, Lenovo, Tesla, etc.
You can wait until just before the next time the device is scanned for filesystems, or perhaps when the next btrfs filesystem is mounted. Beyond that it will start to cause problems.
The other issue is that this will surely go back to the Elite High School feeding to the Elite School. And the Elite Junior School feeding to the Elite High School. And the Elite Preschool feeding to the Elite Junior School. If your parents are willing and able to pay the fee you can drastically increase your chances of acceptance into Oxford University by going to Dragon School and then Eton.
My Quantum Leap
Oh yeah, I forgot about a "knob" of butter.
It's been over-corporatized in an attempt for respectability, with the goal of finally making money. That's something that happens in waves, and eventually you're left with nothing of what you started with. Reddit has reacted to every media panic with waves of new censorship and subreddit bans. You can only do that so many times before you've actually handed your site over to people who 1) either never participated in or enjoyed any of the now banned activity or places, and 2) people who were attracted by a site that was wiped clean, and were disgusted by the site during the period of its greatest growth, creativity, and influence.

People blame it on Eternal September, but it's really handing a new site, barely resembling the old site, to Eternal September and banning the old site.

What reddit is trying to do is to build an entirely new business with new customers, while retconning the brand that it built while becoming a household name. It's rational; there's no reason why reddit should be valued any higher than a 4chan, and they're looking for one.
Another inside joke among academic economists is that the highly ranked PhD students find dissertation and paper topics by looking at low rank publications. Basically the low ranks don’t get into good journals due in large part to their school, so high ranks can just take their work, spin it a bit, and then publish in a top tier journal that their buddies referee.
On a full suspension bike like this, the distance between the rear wheel and bottom bracket changes when the suspension works, so you need a way to compensate for this.
Bicyclists are a tragedy of the commons. This is yet another reason why I'm in favor of complete elimination of public roads in favor of private/toll roads. There is no 'right' to a bicyclists being provided a free public road in the way there is say a right to free speech.

I expect the number to be more like 100%. Just like I expect lawyers and doctors to have attended Law and Medical schools.
The problem is that in the US - that can often mean an hour long walk or more both ways. People don’t want to go out for food if it means walking near a loud and ugly street (where there might not even be a pathway for pedestrians) for over an hour each way…
Congratulations on the launch Joseph! I've talked to Joseph about this project and gotten a sneak peak and it's super impressive what he's built.

The list of apps offered is impressive and the service is expansive and gives back to F/OSS. Excited to see elestio succeed in the future.

For people who want to use F/OSS software but not necessarily to host it themselves and have to worry about updates/etc, elestio is perfect

Could you please (I am asking out of curiosity) provide information about other companies? All I find are about passed tests.

Your example metaphor is good I agree! The developer of the stadium here are the radio altimeters' manufacturer in question.

The 200 Mhz gap between bands had been known. They just didn't want to: a) fix their leakage b) buy the "neighborhood" ie the band.

They had multiple chances over more than 10 years now. And now they use the FAA to bail them out.

We have the expectation, especially whoever flies and uses altimeters directly, that they will be extremely robust. From what I have seen so far a lot of corners have been cut.

P.S. Wouldn't you double think before flying with some equipment that your undergraduate self (EE) would design better? Pay for more band, not with our lives.

Just shy of 200k in TC, heading higher after accepting my next offer. 36ish hours a week, without any real oversight on actual time (I'm currently interviewing and I'm not sure anyone has noticed that I've been dipping out for an hour or so/day for interviews and prep). "Unlimited leave" for the last five years now across two jobs, which as we all know is a scam, but I try to take at least 30 days off per year, usually in two week-long blocks and then at least 1-2 three or four day weekend per month.

I said this elsewhere in this thread, but in tech in the US, you can now live almost anywhere (except for SF/NYC/Seattle/maybe LA?), make an amount of money that will put you in the top 1-5% of wage earners wherever you are, and still have a pretty chill life. I don't know if that'll still be the case in five or ten years—there is so much money sloshing around right now, it's unreal—but for now, I think it's foolish not to try to catch the wave and bank as much as you can.

Tagential thing I learned from your blog post:

> The max(t1.date) and group by t1.state is a useful SQLite trick[0]: if you perform a group by and then ask for the max() of a value, the other columns returned from that table will be the columns for the row that contains that maximum value.

I had no idea that "bare columns" were an actual advertised feature of SQLite — I just assumed the bare column results were a happy accident (a consequence of SQLite's easy-going conventions) that seems to work (i.e. not throw an error) — but should otherwise be avoided, especially as it can't be depended on when migrating to stricter standards like pgsql or bigquery.

I'll think I'll continue to avoid it, but good to know that the seemingly correct-by-coincidence results are actually by intentional design.

It’s not an excuse: it’s a practical reason to not do a thing given finite resources. Somebody has to design the trucks, somebody has to manufacture them, someone has to service them, and somebody has to build the stuff that will charge them in a place the USPS can guarantee the availability of space for and security for their trucks, which practically means USPS or at least USPS adjacent property.

The climate is changing is not a legitimate reason to over-spend, or worse: over-spend, over-promise and under-deliver. Anything they build today is bound to be safer and pollute less than their current fleet, so why hold up replacing the fleet when what they need from an EV practically doesn’t exist outside of exactly Tesla’s supercharge network?

rust is not good for game dev

compilation time is even worse than c++

there are hidden allocations EVERYWHERE that you can't even control

stop trying to push that narrative, it makes rust look bad

rust is nice if you target things like drivers, anything else it's bad

the other day i read people who thought rust could replace javascript

just take a nap and move on, you are delusional
So make that infrastructure publicly accessible during the day and BOOM* you just deployed a publicly funded charging network across most of the country.

*Obviously it's not quite as simple as "boom" but you get the idea.
Oh that machine is a monster. All the memory is HBM2 as well. So it's stacked in the same package as each processor chip, connected with an interposer. HBM gives you 4 stacks, each with 8 single duplex 128 bit memory buses, that can run at 2+ ghz. So that 4.85 PiB is accessible with a raw bandwidth of around 144 PiB/sec. Definitely a monster of a machine.
> Sometimes you need to look at two–three windows at a time.

You can actually tile two windows in a single full-screen (menu-less) view on macOS, and they can be sized arbitrarily as the two windows allow.

So for example you can do the editor/browser pair, or the file manager/preview pair. macOS doesn't get everything about the window selection process right, mind you, but this pairing approach does work pretty well.[0]

You can then swap (slide) between those full-screen views (and other ordinary desktop views) with a gesture, but because it snaps to full screens, you only need a simple swipe gesture.

Endless _arbitrary_ horizontal scrolling will get tiresome, having the window scroll as soon as the focus changes will be jarring at times, and having half the content of one or more windows off the screen at any one time will become cognitively frustrating.

[0] I find it very rare to need to tile four windows on a screen but surely ordinary window manager tiling mechanics can handle that (or Magnet, on the mac).
Irrespective of one’s moral views, whether one consented (to the act, or filming the act or publicly sharing the video) is a serious concern.
Heh, I was just thinking the same thing. A car with all of that "functionality" off? That sounds pretty good to me!
That part is getting a lot better with e-bikes, which is part of why I mentioned them. :) I'm in NYC, where the temperature does vary at least that much between summer and winter, and I recently got an e-bike in preparation for our office reopening, because I wanted to be able to avoid the subway in more weather than I'd be happy using an ordinary bike for (especially while the office's showers are closed!). On warm days, I can easily get up the bridge without sweating if I let the pedal assist do its thing and don't try to go super fast. And on cold days, if I do the same thing, I don't have the problem where I start to sweat under warm clothes - I can wear exactly what I'd wear without a bike (a warm jacket, decent inner layers, and gloves, nothing more complicated than that) and it works fine, too. It's a lot harder if it's more than a few degrees below freezing, extremely hot, or heavily raining/snowing, but I think it's pretty manageable most days.

But also, that's one of many reasons that bike infrastructure isn't enough to displace car infrastructure on its own. Good public transit helps, apart from being a viable year-round transit option in its own right, helps here because it allows people to decide that they can bike on days with good weather, knowing they have fallback options the rest of the time, whatever their own comfort level with with weather may be. And frankly taxis/ride-hailing services can also solve the problem of getting people from place to place without requiring a huge amount of parking spaces.
Yes, if you can hash then that would help. People then turn to putting the video in a frame and adding some music in order to repost it. I suspect the hash though gets rid of most reposts

Another hard problem is user based tags. Many users are basically advertising. They post a clip of something and then say "for the full thing, go here". They then tag their video with as many tags as possible to spam the site.

Now a user comes by and searches for their favorite tag and the tag is filled with stuff that has nothing to do with that tag.

I've seen this issue on Soundcloud, Pornhub, XVideos, and others.

As it affects my favorite tags I often which I had the guts to make a pornhub clone, somehow make it popular, and basically ban/demote or in some way discourage anyone who tags things wrong.

I also think I wish pornhub had content id so that creators could somehow get compensated regardless of who posts their content. Something I see a lot is people posting collections of other people's content and asking for you to support them on patreon to post more collections of other people's content ?!??!?! People suck! >:(
Essentially all education, science, is taited by racist cleptocrats reinforcing there own families importance over time. Think about the decisions that are tainted because of this self importance?

I will say it again, that means ALL RESEARCH (which informs government policy) IS TAINTED by the views appropriotated by these people. That means assumptions, starting and ending points, methodologies.... ie. drug addiction, mental health, treatment of aboriginal populations, behavioural, gene, medical, tainted. Anything, tainted.

Tainted.
> but I'm pointing out the standard explicitly lets vector's constructors fail

Yeah, but that thing has more than one constructor. Since C++/17, the default constructor of std::vector which doesn’t allocate any storage is usually marked as noexcept, i.e. the standard does not allow it to throw anything. This feature allows to make classes which contain vectors yet don’t throw exceptions from constructors.

P.S. The move constructor of std::vector is marked with noexcept as well, i.e. it’s even possible to construct non-empty vectors without any exceptions.
It’s a lot bigger now and therefore has the same problems any big online community has (bad signal to noise ratio). I think this is made worse through the upvote system, but that’s purely my anecdotal take. The niche communities continue to be pretty good. I use askliterarystudies pretty often and get high-quality info.

In my experience even the most niche online communities begin to seem “dumb” after you’ve spent significant time on them, as the once-novel information gets rehashed endlessly.
In fields like Biology or Medicine, where peer review is not double-blind, there's also what I would call a publication bias that perpetuates this elite cartel.

If you submit an article to Nature or Science from, say, Oxbridge it has much higher chances to get in than if you submit from a good university like Southampton or Exeter.

Professors from elite institutions are really well connected to editors and funders. Actually, many editors come from the same institutions. So while reviewers might treat you fairly if you submit from a less prestigious institution (I think this is also questionable), the editorial board will be less likely send you article for review.
It would only take 1-2 republicans to vote for the package to pass it. There are already 48-49 democrats on board.
