> Roads in Manhattan are narrowed frequently to allow more pedestrians.

That's wonderful to hear! I lived in NYC for the better part of a decade and was a big supporter of orgs like Transportation Alternatives and their work with the DOT to advocate for road diets.

At least when I lived there the painted bike lanes were a running joke and more dangerous than just taking a car lane because every block there was at least one taxi or truck blocking the bike lane. And in cases where there was physical separation you had to contend with moped drivers riding at unsafe speeds. The Queensboro Bridge bike path was dangerously overcrowded and every year they claimed they'd open another lane; it looks like that's still "just around the corner" https://nyc.streetsblog.org/2024/04/08/first-look-the-dot-fi... but I wouldn't hold my breath. The Queensbridge Greenway shared use path became a muddy parking lot soon after it opened and it seems like they're still struggling to keep cars off it. NYPD still seems more enthusiastic about ticketing cyclists than drivers who park illegally.

I didn't mean to imply that the NYC bike/ped folks haven't notched some wins. And I used to tell myself that as bad as it was, other US cities were worse for cyclists and pedestrians. But that wasn't true and every time I go back to visit friends and family I'm still grateful when we leave.
I'd agree, it seems like the entirely wrong place to put a feature flag. Personally I'd go for either configuration file or database and then have a process for updating the feature flags.

The best implementation I've seen was in a Java project. Features where enable or disabled by either the properties file or the database. If a flag was set in the database, then that took precedence. New features would always be rolled out disabled in the properties file. Then in a controlled window the new features would be enabled for a few minutes and logs would be examined. If everything looked good the feature would then be enabled again. After a few days or weeks, the properties file would be updated to have the feature enabled by default and the flag in the database deleted in a later task.
IME "I'll just use createElement" leads to "Oh dear, I have to add another createElement" which leads to "I really don't like reading this code". But of course it's a trade off.
I'm looking at a map and really confused about how from New Jersey you can end up in Queens while trying to get to Staten Island.
string, list, map, etc? You have to use an encoding scheme.

As for go / javascript? I think most languages have the ability to inspect a raw buffer.
But then you’d want your compiler to infer loops from tail recursion and then you’d have all of the same problems as this paper cites.

The paper’s title is misleading in that way. It’s describing problems with loops, not problems with C loops.

I worked in this space as a statistician. You are completely correct. The environment is so incredibly target rich and resources are so limited that only the biggest and most obviously winnable cases are pursued.
Fidi is the most underrated neighborhood to live in NYC. Most MTA lines converge there, very secure due to post 9/11 security, not much traffic and quiet at night, and slightly cheaper than many other Lower Manhattan neighborhoods.

Yes, it was a SGI application. Probably used in the movie Hackers.

There was also a Doom file manager where you'd use BFG to nuke a directory. I only found one for Doom 3 but this also existed with original Doom. Nowadays, BFG is only used to nuke git repos.
Yes totally, and then we need stricter regulations to keep this from happening again. Unfortunately every regulation makes healthcare even more expensive and adds more middlemen and makes healthcare companies hire more paper pushers to make sure they're meeting regulations.

B12 can be tricky to pin down. It can be falsely elevated by vitamins.

You need cofactors, e.g. a B2 deficiency could falsely give the impression of repletion.

This is ON TOP of the really loose grounding of accepted ranges for various vitamins. Many of the levels are established on the basis of avoiding severe disease like vitamin D: "no rickets above this level" and B12: "no anemia above this level." Which is completely different than assessing optimal levels.
> “No contaminants” does not seem realistic even in a cleanroom.

If the contaminants don't enter the room or touch the equipment, it's quite realistic. It's weird how many people buy into the silly "why are we forcing industry to do this impossible thing?" train of thought even though the thing is clearly not impossible (and it's been shown to be a self-serving lie on the part of some industry players).

I've never had an interesting coding question posed in an interview, but I did have an interesting homework task assigned as part of the application process many years ago. They wanted me to implement a ML-based engine that determines optimal routes and schedules for freight trucking.

They gave me 4 weeks. I declined (it was an egregiously over-the-top ask), but I have to admit it was an interesting problem.
So, going from a very narrow frequency band (up to 1000Hz) to a much wider range, which can theoretically encode information (e.g. frequency modulation)... Hmm, I'm wondering if comms over gravity is something a sufficiently advanced civilization might consider using, and should we be looking for that 'Hello, world' in some 'natural frequency' like we're doing for EM radiation?

A private office away from my actual home.

I've been remote for most of my career and keeping an physically distinct office/workshop has demonstrated a very high ROI both financially and pyschologically.

It's the best of both worlds: mental separation of work and play/rest; rent that's cheaper per sqft than residential space; work in "town" with home that's quietly removed; a practical workshop with a simpler aesthetic at home; and still no on-site colleagues, cubes, open offices, drama, etc
I jumped off and started using Svelte but have now found looking at job listings all the non tech companies are still using Angular and all the startups/tech centric companies are using Next.js.

I feel like from an employability perspective I shot myself in the foot, but I also dislike both of those frameworks. So maybe I should just quit being a front-end developer and try to retrain as something else.

That seems like the actions of a psychopath to be honest.

That is absolutely not necessarily the case… FPGAs are present doing various things in many, many electronic devices, and many will continue to be FPGAs with no reason to spin an ASIC.

For mass-market consumer electronics what you said broadly true, but a lot of industrial/commercial electronics the time-to-market and flexibility advantages outweigh the higher per-unit cost, because they can charge larger margins to make up for it. (The bit about volumes is correct, yes, you can negotiate good prices if you buy in large enough quantities).
No. I’m asking for citations when your assertion is that flammable hydrocarbons mixed with oxygen in an enclosed container and ignited can not exceed 30-40 psi, or the bursting force of said (often brittle) plastic enclosed container. Especially since garden variety Schedule 40 PVC in the sizes we’re talking about are rated (non-shock) for over 180 PSI and many into the 200+ PSI range but there are easy to find videos of them bursting in spud guns.

[https://parts.spearsmfg.com/sourcebook/SCH40TECH_40WHTPIPE-1...]

And as noted in the prior declassified paper, shock fronts from these mixtures can easily move in excess of 280 meters/second even unconfined in air, with the right mixes.

Goofy? Perhaps.
Life altering? Perhaps [https://youtu.be/KqstP9ics2A?si=Omtp8N7xPW91A5TU] - and yes, while many of those failures in the video are clearly due to improper glued joints (which is a big hint at the pressures involved, and way better than other kinds of failures!), many also involve the PVC shattering. Several in the first few minutes, actually.

I made a ton of potato guns as a kid, btw. Typically using propane. But I always respected the forces involved, because I wanted to not lose an eye, kill anyone, etc.

Looks like some enterprising MIT alumni + the air force academy did some internal ballistics reseaerch [https://arxiv.org/pdf/1305.0966].

Note - I highly recommend against using acetylene, which they did for some of the tests, as it will perform a proper super-sonic detonation [https://www.icheme.org/media/10611/iv-paper-08.pdf] under the right conditions and turn your potato cannon into an IED even if the projectile moves, or potentially even with no projectile at all. Per that paper - “It appears that Acetylene is unique in that it will propagate a detonation at initial pressures below those of which it is capable of sustaining deflagration”. I would have checked this paper which even more directly addresses the topic [https://link.springer.com/article/10.1007/BF02671917] (because I love this kind of thing, obviously), but $40. :(

So looks like as long as everything goes well, they are in the approximate range of 20 psi while driving the projectile, except for acetylene which hit a hair under 90 psi. They used stoichiometrically ‘perfect’ mixes.

My guess is the failures in the videos (and anecdotally) were driven by too lean fuel mixtures, easy to do in some conditions. But this paper [https://www.scientificbulletin.upb.ro/rev_docs_arhiva/full14...] seems to indicate the opposite, and also pressures >= 120 PSI. So I don’t know.

I also saw MAPP gas apparently being used in one of them too (the yellow cylinder attached to a plumbing torch), which would also be unwise.

I think React would get better developer experience and performance if they adopt language coroutine feature to implement direct style algebraic effect. In fact the React Fiber system is already an implementation of algebraic effect.[1] However, it’s “suspending” a routine by raising an exception. Thus unwinding all the call stack, therefore, it needs to re-run that same routine on resume. This is the core reason why they have a performance issue and why they created the compiler to cache values on reruns.

JavaScript has language level coroutine features like async/await or yield/yield* and we have seen libraries using these features to implement direct style algebraic effect. For example Effect[2] and Effection[3]. You don’t need to memoize things if the language runtime can suspend and resume your functions instead of throwing exceptions and rerun them.

You read way too much into my statement. I don't know who you are, or why you care(you spent long enough to get worked up and write a reply, afterall).

My message was simply my opinion as a user, to anyone who may have a similar flow. No more, no less.
I had't seen it! The "clones" feature is cool, it sounds like they're way ahead in figuring out how to use transclusions effectively when coding.

Previously I'd thought of using transclusions for things like long-lived documentation. Now reading about Leo it seems like they'd be just as useful for creating short-term views into one's code. Eg start a refactor PR by transcluding all the relevant definitions into a doc. Now you can start writing PR comments in that doc before you even begin coding, and when you do all the relevant code is right there.

Masters of Elixir: A Comprehensive Resource Repository for Elixir Developers
Hello, Hacker News!

I would like to share a project I've been working on called "Masters of Elixir." It is a comprehensive repository of resources for Elixir programmers, including documentation, courses, newsletters, books, online tutorials, and community events.

The goal is to provide a single reference source for those learning Elixir or looking to deepen their knowledge. I'm seeking feedback from the community and contributions to make the repository even more useful.

Check out the project here: https://github.com/jpstudioweb/masters-of-elixir

Thank you in advance for any feedback and suggestions!

Best regards,

I also think some of the confusion is coming from the use of the term 'weakening'. It is true that the primary jetstream wind pattern is weakening relative to it's stabler state.

That weakening means the jetstream meanders more, with more latitudinal movement in its form.

The strength overall of the jetstream wind is weaker when it's meandering, but can also be much more intense in places.

This says nothing about humidity or energy or pressure, just windspeed and direction.

The problem isn't any one calculation. It is when you update a cell that causes many, many cells to need to recompute.

I assume this is what is happening? The client tries to recompute the data locally. But bails out on cells where it is missing input data. Then the server responds with an authoritative copy of visible data that the client applies over top of its guesses.

MTA definitely doesn’t have 600B to lose, so I’m assuming you mean million. And it’s not the city; the MTA is run by the state. So the city can’t use it to pay for other things, but the state can both divert and reappropriate its budget.

Take a look at the third image in the post: both state and local funding from the MTA have been reduced in recent years, dating back to the FY before COVID.

Similarly, here’s an example of the state using MTA as a piggy bank for upstate ski resorts[1].

Congestion was intentionally and artificially created when all roads were cut to 2/3rds capacity by creating massive bike lanes for bike riders who are reckless.

It was also artificially and intentionally created by adding a massive amount of uber/tlc vehicles. Just stand on any block and watch the cars go by. 90% are not private passenger vehicles.

Before bike lanes and uber there was almost no congestion except for limited rush hours.

There are actually fewer vehicles on the road today than ever but it's an optical illusion of more for the reasons listed above.

This is just more long term political trickery just like the hudson yards project.

Walk around in London where this has been instituted and all you see are 100k+ vehicles on the road.
