Not OP, but I agree with OP, assuming by "people" they mean "people already inclined towards math." Self-evidently, IMO, most students need numeracy much more than they need pure math.

In school, I struggled with memorization & attention to detail. For the life of me, I couldn't quite finish an algebra-heavy problem without writing 3*4=15 or outright skipping a step in a conic rotation or whatever. I'd get dinged every... single... time, and got relatively bad grades.

Shortly later, when I arrived back at higher level math through cs & stats, I could ruin the curve in my applied classes. I'd relied so much on mathematical intuition early on to compensate for a lack of memorization ("what are the steps again? Whatever - I'll just think it through now") that I was quite good at putting pieces together in odd ways to solve data science problems.

Not to mention - with proper context, as you say, all that linear algebra that so annoyed me all the sudden seemed intuitive. "OHHHH so THAT'S why this exists"

I was first driven out of math by a relentless focus on math-as-a-tool, and was able to return at a level where it became more about creating new logic. I'm convinced that I would have thrived in an earlier class that focused on elegance & logic - what makes a good proof? - and I'd have stuck with it.
That's not true, there are various factors that determine currency valuation.

You can have high interest rates, but if the market believes you are going to increase the money supply, that may not be enough to stop depreciation. That's why debt monetization through QE without QT is such a dangerous game.

Interest rates in the US right now are higher in the Eurozone, yet the dollar has depreciated against the Euro.

Lastly, while it is possible that the dollar will not depreciate against other currencies, currencies will still depreciate against assets.
I see the advantage of tying it in with Instagram, I think it will help user growth early on, but I think it will likely inhibit growth later on. What exactly are you signing up for when you sign up for Instagram? Are you signing up for Reels, OG Instagram, or Stories? Stories at least sort of made sense with the original Instagram, but Reels doesn't feel like a fit at all to me. The bloat of the app at this point seems like a barrier to using it.

Maybe they'll be able to spin off a separate Reels app as well at some point? That's the only way I'd ever be interested in it.
Phoenix as a Rails successor does fix most of these issues, in a right way.
> This is spectacularly false. For all non-trivial allocation/deallocation patterns, Rust also uses a runtime reference-counting GC, which is significantly slower than the tracing GCs you find in OpenJDK.

Are you talking about `Rc` and similar smart pointer types? If so, the twist is that in Rust almost all allocations in Rust are trivial in this sense.
My biggest wish for Instagram is to stop creating new ways to format content and give users more control over how their content is distributed. For example, I know a few people with private accounts for close friends or fitness accounts, why not create feeds of posts that people can subscribe to? They have a similar feature with stories/highlights.

This is most likely to boost account #s but it's frustrating to have to follow multiple accounts for one person.
I really love the out-in-the-open development process. It doesn't cost SpaceX anything, yet they attract lots of internet media where people set up streams, discuss progress etc.
The next year should be pretty exciting as they develop things further. Starship has a number of big innovations, which are:

- the raptor engine. This was developed behind closed doors and is sort of finished. We won't see much of it, but it is the most advanced rocket engine ever made and I'm not aware of any upcoming engine that can compete with it.

- Stainless steel construction. What we're seeing with SN5 is the basic tank structure of the second stage. The hopper that flew last year was a neat demo, but SN5 was pressurized and the design is way closer to what the actual starship will end up having. The first stage tanks will also be a stretched version of these tanks, so that's why you see them focus on this so much right now.

- belly-flop landing. To land, starship will be coming downhorizontal until a few hundred meters above ground when it'll make itself vertical to land. SN5 won't have the fins and cone to perform this, but SN6 will. It might be possible to see this before the end of the year - SN6 (with 3 engines) goes up 20km, goes horizontal to burn off speed, then lands vertically.

- belly-first re-entry. Instead of a heatshielf that withstands a high temperature, Starship will burn off speed with its belly, but do it over a longer time period of time so that while the total heat is the same, the max temperature doesn't rise too much. The stainless steel can't take the temperatures ablative heatshields on capsules can. Don't know if Starhip will be able to perform this meaningfully without a booster.

- in-orbit refueling. Starship is big and heavy and basically can't get anywhere unless it's re-fueled in orbit. I don't think this has been done before, definitely gonna need 2+ starhips and boosters to show this.

- superheavy booster. This might be the simplest part of the whole system - a first stage with 31 raptor engines.

Lots of stuff coming in the next few years.
It's like Facebook didn't learn their own lesson from... Facebook.

The biggest reason I left Facebook was because the platform became a jumbled mess instead of its original clean interface. It's the reason why Facebook originally won out against Myspace and why Instagram won out against Facebook.
Fuzzing Rumpkernel Syscalls, Part 2
To play this discussion out further: it depends on the heat and it depends on the motion. I’ve made plenty of Hollandaise (which is a sibling of Mayonnaise) in the blender with “boiling” butter poured in, and it stays quite hot... especially when it continues to warm on the stove top.

If I microwaved it from cold, it would break almost instantly.

Yep. They’ve been publishing seriously for a while now but it is hard to break through. I wondered if it was a conservative publication at the start. But they did the Swan / Trump interview and now I think the brand is on the map.
How powerful is the video editing compared to TikTok?
CCleaner does not remove OEM crapware. It "cleans up the registry" and does other stuff that with time has been incorporated into Windows 10 itself.
Doing the same using Syncthing for syncing. For basic password management across devices without having to go to "cloud", I don't see a better alternative. The new polished UI for KeepassXC on Linux is a bonus.
I find it inexcusable that Teslas don't have voice commands.

Too early to tell, though the brand feels more modern and digital.
Some benefits are for developers. And some are for the users. For example, many users, particularly ones who care about the look and feel of things, prefer when there is a smooth transition between screens in response to their actions.

You simply can’t do that with server rendering (barring hacks like Turbolinks, which are just approximating SPAs).
Even building the barn takes awhile! I built a 8x12' shed working mostly on weekends 7 years ago and that alone took a couple months. Good thing it was in my backyard and I thus already had a house to live in.

Also, I suspect that if you're building a smaller cabin-type house in the woods, you don't also want a barn. Maaaybe a shed.

My dream house would have some interior unfinished space that opens to the outside for use as a shed/workshop. Basically think of a large unfinished mudroom with storage for tools, a lawnmower, shelving, a workbench, and maybe some larger stationary power tools like a band saw and drill press.
Frankly I find that more appealing than the airplane dashboard that are currently MBs. I was actually just wondering the other day as I was driving with family owning one (well, two) if they will take the route of Tesla and get rid of the bazillion useless buttons.
Congratulations on surviving the 32 meter odyssey and living to launch!

Wondering how do you deal with stateful services? You mention an "analyzer process" for external services, what about internal services?

It seems this would work well at a single service level, but would it also be possible to apply the analysis at both a single service and a group of services?
Some form of unit-testing and integration-testing at a service level...

Ah, but the headline is written in sentence case, not title case - as can be seen in the words "launches", "its" and "rival", which are read before "Instagram Reels". Rookie error ;-)
I like everything you said, but one nit:

> Instagram should acquire the differentiated apps and integrate them into its routing.

Are they actually differentiated? My understand was they're just auto-grabbing jobs, maybe based on some parameters the shopper enters.

My problem with this, which is brought up in someone else's top-level comment here, is that there is an implicit contract when I use Instacart as a customer - that someone is starting to shop immediately (or as close to is practical). I have no interest in paying Instacart's pretty high fees and having my job sit in someone's queue for any non-trivial amount of time. If I wanted to do that I would just do grocery pickup instead of delivery. I'm honestly not sure how to reconcile these competing desires while still being fair to the shoppers, which I do want despite how that previous sentence may have come across.
There is no stream being started in DVB-T/S/C as far as I know, since they are actual broadcasts. US cable tv might work differently though.
Perhaps the GP is receiving malware through a targeted or non-targeted advertising campaign.
That would depend on when you bought it.

Picked up 200 shares right before the peak? a modest gain, if that. Maybe you miss the worst of the downturn, though.

Bought 200 shares 10 years ago and now it's peaking? Get them ducets, son.
I'm a software engineer from Italy and went to work for Intel with an H1B visa back in 2012.
The process of getting a H1B visa used to be quite complicated and long even before Trump started dismantle it piece by piece.
My salary was perfectly in the range of salaries from other US workers with comparable education and skills.
I know that because I had plenty of opportunities and offers to switch company.

FAANGS strongly compete for software engineer talent and if one of them (ex company X) would start offering lower salaries the others would likely poach as many employees as they can from company X.

I do suspect though that outside of competitive technology driven companies like FAANGS there is plenty of companies that indeed don't care much about technology and innovation and just want to cut the budget. This is especially true for consulting.

The USA will loose its edge with the loss of the influx of young talented skilled professionals.

"Almost" is to say that no, it's not enough. Show me climate controls on the steering wheel.

No. A very very small minority of people operate anything via voice control. Especially in cars where voice control is universally horrendous.
Stop asking too much personal information, that is why I don't fill many surveys and skip sites/businesses. I am Canadian, ask me what province I am in okay, asking for my home address - NO!

If Apple offered a more fully featured keychain I might just stay in their ecosystem.
You mean the parent is arguably false. Truth-keeping aside, you're saying that people working in contexts where blacklist/whitelist are used, after they have learned the terms, now know those terms, whereas they don't yet know the terms allowlist/blocklist, since they've never heard them. Of course this is obvious, and not what the parent is saying. The parent is saying that, given equal opportunity, one is more semantically explicit than the other. We see this argument often: Naming things, as it goes, is the hardest problem, and when somebody thinks of a better name, there is understandable friction against switching because the previous name is entrenched in practice. This is the argument being had (in this specific thread of a few comments), and you should attempt to have it.
Now this one has disappeared off the front page too.

I think it's being removed by automod because most of the comments are turning into downvote-heavy low-quality bickering over use of the terms allowlist/denylist vs whitelist/blacklist. Automod tends to disfavor posts with comment sections that turn into bickering (which is roughly approximated by ratio of downvotes to upvotes).

EDIT: Aaaaand now it's flagged. I don't know it automod does that too, or if that's explicitly a user thing, or even a mod thing. I wonder if users who don't like the terms are flagging it?
What if it’s impossible to see due to the rain?

There is a huge difference between a radio and a wiper control. Wipers are not some optional thing you can ignore for a while, they’re essential for safe driving and should be accessible to the driver without distraction.

Maybe invest in a couple of U2F tokens that you can keep on a keychain or at home.
It looks like you forgot to publish the '@twig-tool/logs' package. It is not available neither in yarn registry nor in npm.
It's fine for IPv6 engineers to want to make everything directly routable, but in IPv4 the difference still matters, and therefore that's the scenario we need to compare against.

The IPv6 enterprise argument is 'You might one day have to renumber some devices because some other enterprise might have set up overlapping addresses, therefore you definitely have to renumber everything now, and oh, every time the ISP decides they don't like you, because private addresses are icky'. Obviously that's a hard sell.
it's like online ads, if they manage to upsale to 5% customers it's still a huge win.

There are a lot of trusts out there that operate with no full time employees and make billions in revenue. Maybe getting returns on investments isn't really a company, but it's also hard to say something like a hedge fund isn't a company.
Hi all,

I'm the co-founder of an early stage SaaS company. While running the company, we found ourselves tracking our tech and infrastructure metrics by creating 100s of dashboards.

But just creating dashboards didn't help. We needed to spend time and efforts in monitoring those dashboards. We got emails from customers telling us that the platform was slow for them - wasn't this the job of the dashboard?

We ended up tracking everything but monitoring nothing. Setting up thresholds based alerts didn't work because of the volume of metrics and stuff like trends and seasonality.

This got us thinking - Is there a better way to work with dashboards?

Tools like Datadog and New Relic were way too complicated for us.

We've documented our thoughts here, and I really look forward to understanding if this is genuinely a problem faced by founders, or is it all in our head!
The real question is, can their stamp be trusted.

I don't think that's particularly obvious. Lots of people raised serious concerns about TikTok, and lots of organizations banned it, long before the President started leaning in.

Model 3 owner -- when you press the quick wipe button on the left stock it brings up the wiper interface menu to adjust the wipe speed and the auto wipe button. It's very quick and only requires a short glance and one screen press.

One way to improve it would be after the left stocks quick wipe button is pressed, let us adjust the speed with the steering wheel control wheel with a volume based auditory click to indicate it's gone up or down. Although those are used for volume and speed if cruise or autopilot is enables so it would need to only stay in wiper speed adjust for a few seconds
There's a physical button to turn on the wiper. It just doesn't have the full range of controls for speeds and on/off as physical controls as the automatic wipers are supposed to be used instead. The automatic wipers aren't particularly good though which is why people end up fiddling with the controls. The touchscreen interface isn't too bad, it only takes a single touch, but it's not like the tactile experience of a physical stalk with all the wiper options.
Is there a free trade agreement that’s being broken?

From what I can see, China does not allow free trade. While the US did.

And because this was so “unfair”, the US decided “fuck it, we don’t want free trade either”.

It won’t gain the US much, and will drastically hurt it going forward, especially considering how much the US has benefited from its open business environment in the past.

Honestly, this is pretty much the definition of childishness. You don’t find something fair so you react to it, instead of actually considering the benefits and downsides of an action before making it.

It’s the immaturity and short sightedness of the American government’s behavior, which is the complete opposite of how the US has acted in the past as far as business is concerned, at least, is what will hurt it the most.
Or, you could just drop dead.

A DBA I had worked with years ago disappeared from work. Nobody on the contract knew where he was. After a week or so, his parents, who lived maybe 100 miles away, called the contract manager. He discovered that the man was in the county morgue as John Doe, having been found dead on the sidewalk outside his apartment, without ID on him.

I assume most HN readers are

- younger than the DBA, who was probably in his mid-fifties
- in better condition, for he was obese
- in a wider social circle, for he was pretty anti-social

Still, it isn't bad to have people who will know that you have disappeared.
Terrific stuff and glad this is becoming industrialized at scale.will keep you guys in mind as we expand
No, Volkswagen is even worse. Have a look at the Mk8 golf or even the ID.3 - literally everything is a touch surface, made out of shiny black plastic. Volume controls, climate controls, "buttons" on the steering wheel are tiny touchpads.....it's truly truly awful. I've used the latest Golf recently and the fact that the only way to adjust temperature is to swipe your finger on a tiny touch surface without any feedback is just mindboggingly stupid.
Like all those old furniture or door locks that I just assumed were lost causes, many locksmiths can actually make keys for them. Not usually a serious need for it but if you were selling an old piece of furniture you might do it. In my case we have a bedroom closet we'd like to lock some stuff away in when we go away and have someone come in to feed the animals.

The ability to make a key for locks which have no key is another, even if those locks don't have removable cores (I'm thinking of mostly padlocks here). That's a really cool thing called impressioning, where the mechanics of the lock (pins pressed down into the keyway by springs) are actually used against it to progressively turn a key blank into a working key.

Master keying is another great example (when multiple, different keys work in a lock and you can have one key that works in multiple locks, such as a small apartment building).

Also a lot of ancillary things around the lock but not the lock itself, for example installing deep screws or replacement anti-kick hinges (door devil or door armor). In theory those are DIY things but in practice you can spend a lot of time trying to get alignment right (especially with a deadbolt going smoothing in/out), but it's something a locksmith does all the time.
Kinda lines up well with MS talking with tiktok. Wonder why MS wants tiktok still? The US and India banned them and now Instagram copied them too. I do t know how the inluencers move across social networks but why would users stick to tiktok? In that scenario why would MS want it unless its for an extravagant discount?
I wonder if this is a price thing or more of a result of Tesla's development model. With a touchscreen, you can design and iterate. UX can be delayed until the latest stages of development when you already have physical designs in hand. Then again, we're probably over thinking it. I'm sure cool factor was the #1 reason for this sort of implementation.
