> How long are the school days?

I don't know of a private school around here that has school days with defined length. Children are learning asynchronously from various physical and digital learning materials, collaborating together on projects, and having private consultations or small group lectures based on their requests. Yes, the children are actually eager to learn stuff there!

> 8.30 to 4pm is a long day for a child to sit in front of a screen, without much freedom.

Not a single private school here is forcing children to do that, they have to care about children happiness and success - their profit depends on it.

All public schools here do that, and don't even allow children to have a pause for lunch (yes, really - e.g. both my sister and brother are forced to sit in front of a screen from 8 AM to 3:30 PM [7 AM to 4:30 PM 2 days of the week] with only 5 minute breaks each hour). It's extremely wrong, I agree. Sadly, not forcing your children to be present as the school requests is a crime.

> a lot of what is fun about school for younger kids isn't the learning or even the activities, but the doing things together and figuring out things as a group

Yes, absolutely! The private schools around here are frequently taking the children outside, on various field trips or excursions, and the children can meet at the school in a safe way (small groups, etc) to do projects and play together.

I still haven't found a public school doing anything resembling that now. And pre-pandemic public schools were about sitting quietly without movement and writing down whatever the teacher writes on the whiteboard, and about guessing answers to frequent stressful tests - basically nothing has changed nowadays, only the parents have now noticed how miserable the children are.
> Here’s a lesson for people running companies now: BB failed when they stopped marketing to boring suits, and started trying to compete with the Motorola RAZR, then the iPhone.

But here's the thing: Suits all pretty much wanted iPhones. I recall one of the most requested feature on the iPhone was Exchange support.

And their custom messaging thing just wasn't valuable enough to keep users around (hint, the real high value messaging platform for business is and always has been Bloomberg).

Looking at devices like the Storm and playbook, I wonder why blackberry couldn't execute. Talent gap with Apple?
Security guy here. I had the chance to look over this project and try it out today. I have no less than 5 ways to acquire root privileges from an unprivileged user in the 15 minutes I looked at it. Has anyone audited this distro in the past 10 years?
well, yeah. if you don't have air cover from a team or manager and don't appear to be engaged in shared suffering, it's no surprise people are going to ask questions, both from above and equal level. other labor will resent your non-suffering (how come /they/ get to leave on time?) and management will wonder whose reports get such a cushy setup and why.
You're forgetting to double count for "incest".
... and now you will presumably give us an example of a case similar to GME where collateral requirements were not raised so we can see that the treatment was not standard?
I was there as a developer and a consumer. I don’t remember anyone laughing at him for selling books. It was an obvious play to most of us.

Speaking anecdotally, going back to school for an MSc allowed me to pivot from an engineering career in the transportation industry to the data/software field. It would've been more difficult to get interviews for entry level roles without the shiny new degree from a school that was - quite frankly - more prestigious than my undergrad, however I can't say for sure that it's benefited me materially beyond that initial "start". Experience is much more important once you're in the field you want.

I also continued working full-time while pursuing the degree half-time, which alleviated the risk of leaving a stable job. MSc degrees are much less likely to be fully funded than PhDs, and some companies will even reimburse your tuition as well.
Ask HN: How do you measure your development team?
As a newly minted engineering manager, I'm curious how others measure their teams. I'm not particularly interested in trying to understand if particular developers are "good" (which I consider pretty much impossible to based on output) but if the team as a whole are performing well.

Some of the metrics I'm experimenting with at the moment are:

- Merged PRs in the last 30 days vs previous 30 day interval
- Mean of how long work takes to get merged after being raised as a PR, compared to annual average
- Mean of old PRs are when they get closed, also compared to annual average
- Mean of average age of open PRs

I think that this gives me a good snapshot of how efficiently the team is currently performing and highlights areas to me where I need to drill down into more detail on what's going on.

I'm curious to see how others are doing this.

> The same is not generally true for Linux binaries – these usually do go through glibc, but direct syscalls are possible (through raising the appropriate interrupt or instruction).

OTOH Linux having a well defined set of syscalls you can very convincingly fake being a Linux kernel. That’s what wsl1 did. That’s also what SmartOS does, which allows it to mix native and Linux (LX) zones.
I'd argue that the customer experience of Amazon has declined dramatically in the last few years. Maybe there should be more internal viewings of that video.
> This journey began some 27 years ago. Amazon was only an idea, and it had no name.

It had a name, and that name was "Cadabra".

It didn't become Amazon until Jeff watched a documentary about the Amazon River. His lawyer had already turned up his nose at "Cadabra", and Jeff was looking for something else.

It's also worth noting that the idea didn't grow over time - Jeff always intended to build something like "Sears for the 21st century". The bookstore was just the way in, not the long term plan.

from screenshots I have seen lately, I'd bet that at least 20% of RH users have no idea what a limit order is.
It is a constant in any vaccine, including the "lowest" performers from Sinovac and Sinopharm. At this point, I'm inclined to believe that any resonably effective vaccine will have this effect.
So far every single complaint I have seen about wayland is something that wayland actually supports but that a specific program hasn’t been updated to use yet.
I'm fairly active on the Python slack channel, and this very question comes up really often when people ask for help, and in my experience, is basically never meant as disrespectful.

As for the small differences in semantics, I'm not a native speaker, neither have outright negative connotations to me, but I feel like getting tripped up on such a small thing - and simultaneously assuming the interlocutor's intentions - is kind of overblown.
I have seen on Twitter that Robinhood was unable to use customer funds to satisfy clearing deposit requirements, but I couldn’t find an actual authoritative source on this. Is this correct? It seems to me that, to secure a $300 purchase buy a customer, Robinhood ought to be able to use that customer’s $300.
People ignore the clearing house because they don't see it, they don't interact with it, and they don't have a customer contract with it. For all their practical purposes, the clearing house doesn't exist.

It's obvious from RHs statement that they are stuck between the DTCC and customers. They are not willing to call out the DTCC because they are fully at the mercy of it. So they are trying their best to be positive and forward looking, trying to offer help to rally around something totally outside their control (real time settlements).
Both had two vehicles lost in space/reentry, the shuttles just held more astronauts. In terms of percentage of fatal missions the two were roughly equivalent, with Soviet failures front-loaded into less sophisticated and less safe early vehicles while the US failures were later on an overly-complicated system design.
Well, we've taken your approach and killed 300k in the process, so I guess we could play at being tankies in the '90s and say "If only the Communism were properly done" or we could revisit the approach.

Of course I am healthy, my family has had the vaccine or the disease and punched through, so I don't really care all that much.

In this case, it's more like halt OR catch fire.
> When you expand it to institutions, real-time settlement means having to warehouse all the funds they might need to trade with in a day with their prime brokers as cash. Not Treasuries. Cash. Because their broker has to be able to wire out that $1bn instantly.

I see two solutions here, either they sell the treasures (with also instant settlement) and then buy, or they could trade on margin backed by the securities. Or am I missing something?
They landed a lot of falcon 9 first stages without legs on the water, vertically, to test the control system. And a number of attempted barge landings with legs failed, before the first successful landing. Now it's almost a routine thing.
Whether you would be better off with the $5 trade or not is dependent on how many shares you trade at a time.

It wouldn’t have been an issue if Robinhood had been upfront about their pricing. They still would have been a good deal for many retail investors, but they instead chose to lie.
The data the EMA (at least, the public stuff) is from the first "lock" of the data for analysis - November 4th. The current preprint from Oxford is from about one month later.
If I remember right from The Everything Store Amazon hasn't had a COO title since a rough experience with Galli in 99-00.
Completion is not an issue. The problem is that upper case just looks ugly. Like huge fluorescent decals on an otherwise streamlined matte black road bike. They put a lot of effort to create an über-elegant naming scheme, and then they spoil it for no reason.

He shares the vision of Gerard O'Neill. Making it reality will require large amounts of money.
No one minds what you use, it’s the people who go online and post complete lies about what wayland is and what it is capable of. And then they feel entitled to tell other people that they are wasting their time on wayland instead of working on X12.

No, you can alternatively pay money for a different tier of license that lets you turn it off.

It doesn't have deep, grounding values.
"Simpler" is subjective and sort of beside the point of Occam's razor. The razor is about choosing the competing hypothesis with the fewest assumptions baked in.

"When you hear hoofbeats, think of horses, not zebras." A massively orchestrated conspiracy requires a lot of assumptions and so probably violates the razor.
Warmer... but not quite. Governments are defined by a monopoly on force. Whoever distinguishes "murder" from "homicide" is the government, and that government's territory stretches as far as those definitions are in effect.

Would also want to know, once you decide the maximum size of a corporation, exactly what happens to it once it exceeds that size, and who determines that it has infact exceeded it, and carries out whatever the plan is for what happens at that time.
Exactly. Bill stepped down in 2008. Balmer was CEO until 2014. Oddly that’s when their products started to turn around significantly.

Cook has made a lot of original Mac power users completely pissed. He’s gutted entire software products that people relied upon using. He’s probably why we had the half decade of MBPs developers didn’t like. Etc. His best accomplishment has been the services stuff and maybe the M1.

Identifying bounded contexts is a critical part of organizing extremely complex systems. You might have a Customer model that supports all contexts of usage, but in a certain bounded context you could know that only certain things from that type are applicable. There are a lot of ways to model this explicitly, but sometimes just having a clear document that expresses what these contexts are and what is involved in each is sufficient.

This also alludes to the benefits around separating your functions from your data. If your domain model is just data and the functions live elsewhere (i.e. within a separate abstraction representing each bounded context), then you have tremendous amounts of flexibility with how the system is composed on top of the model.
FDA still hasn't authorized the AZ vaccine
I've come across people using "best practice" as the sole justification for doing something in software engineering, but thankfully it's rare.

Where it's not rare is medicine. You regularly hear the term spat out like a weapon, particularly in big hospitals.

It's a very poor way to justify something. It's a statement of the obvious: everyone agrees you should use the best or most efficient way of doing something. What people don't agree on is what that is. So it's "we all agree we should be doing it the best way, and I say the best way is ...". You get no indication of why it's best practice, or how it's been chosen, or who chose it. Its more an appeal to authority.

There is another term in medicine that's also bandied about frequently: "evidence based medicine". Unlike "best practice", it assums the obvious: everyone agrees we should be using the best way. It's telling you how the best way way chosen: from the evidence. More importantly it's also giving you permission to improve on it: find your own evidence. If you asked for to see evidence for "best practice", it's often seen as an attempt to undermine authority. If you asked to see the evidence behind evidence based medicine, the reaction your likely to see is "oh, you get it, here is what I have".

When I hear "because it's best practice" or "this is best practice" now, I shudder. It's not an invitation to be part of a team working to produce the best outcome. It's telling you you're a minion, and you'd better follow the rules.

But I think you are right in one sense, the reason we see it used far less in software development is we can often shoot something down with a few sentences of tightly reasoned logic. Evidence is often easy to come by. Medicine doesn't have that luxury, the body is too complex to reason about. It does have rigor and scientific analysis, but it takes a big studies and a lot of effort to gather.

Company US. Me Europe.
> in the US it is not playing much of a role

That's because the FDA is waiting for the completion of AZ's trial in the US. This should be definitely better run than the meta-trials done elsewhere and give clearer numbers.

A likely readout would be in March, or April.
> Amazon is amassing this money by NOT spending it on the economy

as the sibling comment notes, amazon is not amassing money. rather, amazon has amassed value.

you might want to familiarize yourself with what a corporate valuation is, and means.
Musk made his initial money at PayPal and then went on to do much weirder stuff. I wonder what kind of weird stuff we can expect from Bezos, having secured Amazon-scale seed money for it.
When you plug your laptop in to a 4K screen it sets the 4K screen at 200% scale and the laptop at 100%. When you move windows over the screen border they switch scale. On X you either have to pick one scale or have windows die and be spawned again on the next screen
It's only voluntary if they don't get too large. See: company stores. Or basically any megacorp in cyberpunk genre.

Is the scaling algorithm specific to the wayland implementation? I saw a github thread about configuring it in sway but wasn't able to find anything about KWIN. I'd also love a flag to just disable scaling on a per-xwayland-app basis (so I could use the --force-device-scale-factor hack) but couldn't figure out how to do that so if you know something off the top of your head it'd really help out.

Anyway thanks for the tip!
The demand for products has generated 1.3 million jobs. It's a fallacy to think the jobs wouldn't exist without this company or this billionaire.
I agree. Amazon's upper management should really do a mystery shopping exercise themselves to see how dysfunctional their (both Amazon.com's and AWS's) support has become.

That's really good. My only problem is I suck at crosswords. It would be cool if you had a beginner or easier section.
I remember that too and the main issue was that BSD didn't have an answer to logind and it took them a while to port later versions of GNOME 3 because of it. You can't seriously expect Red Hat or some other Linux distribution to drop everything and figure out the best way to get new features to work on all the BSDs before they release something, that's something only the BSD developers can do. If the "dog" here is supposed to be BSD, the wagging is not working on them.
> This is true of the multiverse too.

Okay, this is just going in circles. Up above you accepted that multiverse theories did make testable predictions. And they do, which is what makes them science.

Surprised that Linux From Scratch hasn’t been mentioned. Probably the best soup-to-nuts walkthrough out there for learning deeply about Linux.

Indeed, even the practice of calling certain vaccines "2-dose" or "1-dose" is somewhat arbitrary & misleading, reflecting rushed early decisions about which courses to test.

The Pfizer/Moderna mRNA vaccines might be just as effective, 30d-onward after one dose, as the "1-dose" J&J.

The tested 21d/28d spacing for the mRNA vaccines might be far shorter than optimal, so the ad-hoc "emergency" delays of booster shots by many jurisdictions might actually be benefitting long-term immunity.

The "1-dose" J&J might benefit greatly from a booster 30d, 90d, 180d later.

Even the dosings could be far from optimal, with some hints that half or less of the mRNA vaccines may be just as effective, especially in younger patients. And of course there was the AZ/Oxford glitch that mistakenly gave half the intended dose in the 1st shot - & that subgroup seemed to have even less disease after the 2nd full-dose shot. (While this could be a statistical fluke, maybe also a "booster" that's stronger is read by the immune system to mean that the disease is continuing to become even more of a threat, so it reacts even more strongly than to a "same as we beat before" dose. Until lots more study is done – who knows?)

So: people who treat the officially/rigorously evaluated doses/schedules as "optimal" or "the only safe course" are way overclaiming what the data shows. They data we have are a series of singular draws from the possibility-space, showing some points of reasonably-safe and -effective approach.

With plenty of other data constantly arriving, hinting at other equally- or more-effective approaches, regions & practitioners should be free to use their best-judgement to navigate risk/reward tradeoffs.
