Is it a road design failure if it's more dangerous to drive above the speed limit?

In Sweden we have some roads with a lot of accidents caused by people driving above the speed limit.

They fixed this by installing automated speed cams. The goal is not to give people speeding tickets but to get drivers to slow down. It works really well so I actually believe this new Waze feature will be really handy.

Edit: Btw, I use Waze to get alert about the speed cams.
It isn’t just tech problems that drive this kind of stuff, SWA couldn’t get a deal worked out with AMFA to use bag scanners until 2016.

> Southwest said it will begin scanning bags on the tarmac this year to improve accuracy. Other large U.S. airlines already use this technology. Southwest's contract with bag handlers did not include a provision for using scanners until 2016. The airline then spent time evaluating technology and testing scanners at a few airports.

GitHub stars/contributions etc are used as a metric for hiring. They might end up with a better billing rate for having code merged into a popular library.
Ask HN: Do you know of any live B2B applications built on blockchain?
Other than large enterprise DeFi projects (e.g. JP Morgan, Goldman Sachs etc) are there any blockchain applications aimed at the B2B space?

I'm struggling to find anything that I'd consider to be an app, product or platform built on a blockchain.

I’ve seen it happen and it’s always strange that they seem to not realize the crew will be unusable until they arrive … I assume they had been trying to get another crew at the same time.
I thought this stuff also gets more likely to happen as you get towards the end of the month as you are close to the max number of hours the pilots can fly per month (100h in the us per calendar month), making pilot shortage cascades even more likely to happen.
Is resumption difficult or is it resumption and then make whole the tens of thousands of customers that were supposed to be moved a week prior?

No idea what SkySolver actually does in totality, I'm sure it's complicated but I would think a flight crew could indicate where they are right now and then it could maybe pickup the next possible course they could perform. Not sure why the phone lines "jam up" exactly, don't you have a hierarchical management structure for this sort of thing? Or do 1000 pilots all report to one person?

They've got like 1000 planes and like 100-150 destinations, it's not the traveling sales man problem, an optimal plan isn't needed now so much as a functional one.

Of course, it's easy to bitch about it not being hard when I've never seen the code. Maybe is also tracks hours and does payroll and a dozen other functions.
So you believe that in the same situation all people are equally likely of committing a crime?

So everybody in the US just has a random small chance of becoming a school shooter or serial killer?

I assume you support complete elimination of the criminal justice system and courts then, because in your worldview it seems criminals have no agency and the chance of them committing a crime is 100% a function of their environment.
I switched to Mac in summer of 2021--right to an M1, never had an x86 Mac--after running desktop Linux in various flavours for the previous 23 years: RedHat 4.0, then Mandrake, Debian, Ubuntu, Arch. It's fair to say I've been a developer for that long, too, if you take seriously the notion of a 10 year-old mucking around with C socket code on a 486.

Pluses and minuses, but overall very happy with the switch.

- Biggest con: I miss the raw efficiency, unparalleled speed and superior ergonomics of my i3wm bushido, and will never match that in any conceivable fashion on OSX (yes, I've gone through the whole Yabai/Amethyst/etc journey, and ended up ditching it all and just going back to vanilla. Those half-hearted efforts at a tiling window manager just kept hard things hard and made easy things hard, too.)

- Biggest pro: better hardware (which I realise isn't an OS attribute), never having to care about how my computer works or fix much of anything, lots of seamless and turn-key behaviours that just make sense (particularly vis-a-vis suspend and multi-monitor stuff), and (surprisingly to some), it's refreshing to be able to inhabit a common universe with other computer users and talk about the same sorts of stuff.

Nobody really ever understood my Linux gibberish while I had only a distant idea of what a 'Finder' was that went back to System 7.5.5. It's nice to have more friends.

- Biggest misconception going into OSX: that one actually has to use GUI stuff for much of anything. Nah. The browser, iTerm2, VS Code, and Mail is where I live, same as under Linux. Mostly just the first two.

- Biggest misconception about desktop Linux from Mac users: that it requires so much care and feeding. I ran Arch, of all things, with its continuous rolling releases, from 2016-2021 and although the initial setup had a long tail and was ultimately an investment of a few days, nothing I can remember ever broke for me afterward -- not on desktop, not on laptop.

Mac users tell me they're sure things did break for me, and that I just internalised my Linux trauma. No, they really didn't. It was shockingly stable. It was just kind of mediocre in other ways that start to have more meaning only after you've spent enough of your life tweaking your desktop experience.

Edit: I didn't look at the survey in detail, but I hope they make a distinction between desktop use and server use. Sure, I use Linux for development. I'd even say predominantly. I think of my MacBook as a nicer GUI for all my Linux work.
Not entirely orthogonal? If the fixing issues is manual (therefore slower), that means that once issues start happening, it's slower to recover, thereby making a total meltdown more likely. And when a total meltdown occurs, recovery is manual, therefore slower.
Hit the nail on the head. Look at what companies do, not what they say. A company doing multiple day interviews is not "desperate".
It isn't normal for an employer to not even know where flight crews even are physically located without a phone call and then additional phone calls to get them scheduled onto subsequent flights.

Then you tack on a hugely understaffed call center and problems with their phone systems and you have a hell-storm.

I'd imagine that, as people in poorer regions in the world get access to laptops, we'll see a big increase in free operating systems. Sure, you could crack Windows, but why would you? Windows 11 isn't really good, and cracked software gets no support. Might as well go for a legal Ubuntu with lots of community support and decades of online help for all possible issues. It's a modern OS nowadays.

The real question should be: would most developers WANT to use a Mac, if given the choice?

Personally, I think OSX is the superior of the two simply because it's stable as can be, takes no (and allows almost no) tinkering to get working. Controversial opinion, I'm sure.
Major benefit of Airflow is the number of already implemented integrations. Importing data from GCS to BigQuery, copying data from Postgres to GCS, KubernetesPodOperator and so on. IIUC with Temporal you get only workflow management which can be easily integrated with any application to implement business logic. And this is great, because implementing business workflow in Airflow is even more awful than the Airflow itself.
But for any ETL or plumbing job Airflow is IMO better due to existing integrations.
> Hence the need for a “full system reboot” over many days.

My understanding is that the full system reboot wouldn't have taken all that long, it's just the the company was trying to do a major fix while keeping whatever was still sort-of-working running. As any sysop will tell you, patching a running system is all kinds of crazy risky.
I played it all the way on the Deck with zero issues.

It's the first game that made first person wall running actually fun and easy to do even for a casual player like me.
AIUI the problem is they're using the same lines for passenger and crew rescheduling. So they don't know where their pilots and crew are and can't communicate with them when the lines get hammered with customers trying to reschedule their flights that are canceled because they don't know where their pilots and crew are to staff them.

Ask HN: How to get into algorithmic thinking and leetcode?
My company looks like it‘s dying and I want to hunt for a new job or at least become interview ready enough, in case push comes to shove.

I can build you scalable CRUD apps from https ingress/terminator to dockerized HAProxy/nginx/traefik api gateway to ouauth2 protected spring backends using SQL/redis/bigtable/s3/sns/sqs and despite not ever having been a frontend developer, I probably know more about angular, JS and browser quirks than your average frontend junior. For my bachelor thesis, several years ago, I developed a simple react native app. I am a backend dev for 11 years now, but also a jack of all trades. I feel ready to talk about application/system/solution design/architecture.

I also like to write documentation, talk to third parties and engage in requirements engineering. You can confidently leave me alone with third party partners. I have done hiring and interviewing. I hold a MSc and worked at two companies you have heard from, one of which produces applications you probably came into contact with.

Yet I can‘t solve any easy leetcode problems. If I can, then maybe the n*n brute force solution. Medium and hard problems? Absolutely impossible. Any work on it gives me severe anxiety, which makes even dumb memorizing solutions hard. I love programming, but I hate algorithmic thinking, algorithms and puzzles. With a passion. At least I can do fizz buzz...

Do you have any input for someone like me to become competent with leetcode?

Anyone else in this predicament?

> 2. Never give anyone a reason to dislike you

I'm someone who tends to get along and work well with others. That part definitely has its advantages for employability (and life in general), and is recommended. However, taking it to this extreme is just dangerous advice. Constantly being a people pleaser can carry enormous risks, especially (but not limited to) to yourself. It's important to learn to be ok with people disliking you sometimes.

The interview I saw with one the exec seemed to indicate that even under normal conditions when a flight is cancelled each crew member needed to call into a call center to be reassigned.
With some tweaks to your second paragraph, the description fits CMake:

In reality you just end up [with] a shitty, nerfed version of a programming language, that [...] users can't understand, because you still have to understand [CMake's] logic to [utilize its magic behavior], oh and [the] documentation is terrible because devs don't bother with the boring stuff. Most of the time [you] end up implementing [workarounds] anyway because [CMake doesn't] actually work properly.

Thank goodness Honky Tonk Train Blues by Meade Lux Lewis will finally be public domain.

But you'll have to wait another year for Pinetop's Boogie Woogie by Clarence Smith (who died before the 1929 stock market crash).

In all seriousness, the first one is considered the first Rock n Roll song by some scholars. (you'll have to go archive.org to get the 1927 recording - youtube only has later ones - https://archive.org/details/78_honky-tonk-train-blues_meade-... )

We may be talking past each other. I'm talking about applications for unremarkable positions at large corporations where the application forms are either branded by the company or done through something like iCIMS, Taleo or Workday. You create an account and then you're faced with several steps asking for who knows what. The experience question might be "List all past jobs starting with the most recent" with no date limit. Later on you'll have to agree that you answered everything fully and honestly or you can be fired. Maybe I'm a fool for taking that seriously but the meaning is straightforward to me.

These are also the sorts of positions I think people are talking about when they talk about HR being a barrier, filtering on keywords, or how important it is to network around them before applying. So I don't think it's a matter of the company being stuck with software they can't do anything about, instead the hostile and opaque application process mirrors their actual hiring process, or at least I assume so. I'm happy to hear if you have any insight from the recruiting side at these places.
Most old books are effectively disposable decor - the industry prints them by the millions and many have a limited life akin to the Dreamweaver how-to's. The "last a lifetime" highly sought-after books are truly the exception here.

For archival purposes you can go see if it's in the Library of Congress or scanned into Internet Archive, and if not, that's a project you can opt to take on(but it's pretty high effort). Quickly checking for resale value as other comments suggest is also not hard, just expect that most of your stash will go straight to the bin, and getting more out of it means making it your job.
I'm not the grand parent, but your comment stuck out to me.

> I don't think that's fair as developers spend ages customising everything anyway

I've got into development. I use KDE Neon now and really, the only thing I customize on a new install is left single and double click defaults in the OS, changing system performance mode to prefer performance over battery and install the IDE and Yakuake for a better terminal.

Other than that, the starting development for me is literally just installing the IDE, cloning the repository and opening the project file (and the IDE will pull in all the dependencies, linter settings automatically).

> I can open a terminal instantly and start writing instantly.

One of the best things about Yakuake I love is that it's literally that. Hit F12, multi-tab terminal slides down like the old quake console (yes, that's where the name came from).
This only focuses on using ed interactively. IMHO, ed's greatest utility is in scripts. For example, I still use "diff -e" as I find for small patches, it is more concise and no less readable. YMMV. I also like ed for non-interactively editing large files.

sed is most preferred, but IME there are some simple tasks that are not possible (or exceedingly difficult) with sed but possible with ed.

For example, moving lines and joining lines are obvious ones. Another is using line address "0", namely, with the "r" command.

Both sed and ed allow reading in a file after line 1 but AFAIK only ed allows inserting before line 1, at "line 0". According to the ed changelog, in 2006, the source was changed so that the "i" and "c" commands treat address 0 as address 1.

For example, a common task for me is to insert the contents of file #1 at the top of file #2.

AFAIK, this is impossible using sed's "r" command, but it's possible using ed's "r" command.

test $# -eq 2||exec echo usage: $0 srcfile dstfile
printf '0r '$1'\nw\nq\n'|ed -s $2

A less space-efficient solution, without resorting to fifos, might be something like

cat $2 $1 > $1.$$.tmp;
exec mv $1.$$.tmp $1;
Outer Wilds is a profound, thought-provoking work of art.

A tip anyone encountering this comment: If you like Sci-fi, story-based, exploration games -- Just buy it. Just go play it. Don't read a single review. Don't look at YouTube videos. It's the type of game that you can truly only experience once, and the less known before entering that experience the better.

Also, play on Controller -- The game has a lot of spaceship flight which is pretty frustrating on keyboard/mouse.
The phone reliance in this case is for dispatchers to know where crews and airplanes are. In the article crews will call in for location and assignment (where to go to serve a flight) but are on hold for hours because there's not enough people to talk to and, I guess, update something that looks like this:

This has been refuted over and over again by people who aren't entirely clueless.

What's even supposed to be the logic here? Where do you think that "$250M" figure comes? Why are you assigning some special meaning to it? It's pulled out of the ass of the very same judge who granted SBF bail.
> There are still a number of major airports that are slot constrained

Major airports are major airports even in a point to point system. If everybody wants to go into or come out of NY, NY's airports are going to be slot constrained.

Also when I say "winding down" I don't mean "killed entirely", most airlines still have home bases, and mix point to point with regional hubs (especially for international flights).

But at the height of the hub-and-spokes model, unless you departed from or went to a hub you'd always need a layover.
No, I don't think it's a web app at all.

It would definitely be using native UI components, which a normal web browser won't give you via the rendering engine.

But that's as native as it gets. The control logic for how those components operate outside of how they're internally built is likely done w/ React / JavaScript, instead of native.

In a complex enough system, it's reasonable to assume that at any point in time something is broken and the system is not running at 100%. What this means is they probably had their reporting/fixing system running at the thin edge all the time, and once the failures exceeded a certain rate, it was game over. The fixing could never catch up.
The NYT comments section is all over the place. Some people don't seem to "get" soundtrack music. "It's boring." "It's nothing without the show." Etc.

Soundtrack music isn't meant to stand without the film or TV show or game it's created for. And some, probably most, doesn't. But you can have a real winner if the music stands on its own as well. The Twin Peaks soundtrack album does, for me...and I've never even seen the show. Some composers are better at this than others: John Williams, Howard Shore, Maurice Jarre, Korngold, Badalamenti are among those who can stand alone (IMO). Bear McCreary is one who stands out in my mind as being an excellent composer, but whose music is virtually unlistenable without the visuals to go with it.
