Umm.... yes? Age appropriate, of course. We didn't learn about "drawn and quartered" until 9th grade, when we read "A Tale of Two Cities."

But I'm more concerned about this part:

> The stigmatization of the kinds of tests that are our main tool for assessing whether or not children are learning

I don't believe standardized testing is as useful a tool as trusting the teachers.

Standardized testing is not being used to tell that student X had a problem with concept Y and needs further training. Especially not if the student only gets an overall summary, and even then only until months later, and perhaps even in the next school year.

Standardized testing is being used to punish schools which don't rank well (often from poor neighborhoods), instead of providing more funding and other resources to those schools.

> I think everyone agrees that you can, in principle, assess someone’s competence in a given subject area with a test

Really? I want to see the test that can, in principle, access someone's competency in software development in a given job role.

Companies would pay a lot of money for one that was more effective than the crappy-assed ones we have now.

> And if you want to compare different people, you need to give them the same test.

Where's the test for the fine arts and music programs?

Why are the tests always stressing those topics which are easy to test?

Why are students nowadays being required to pass those tests in order to graduate? I mean, when I was in school we had assessment tests that had no impact on our grades or graduation status, and they were used for exactly these sorts of assessments.

> All this would be uncontroversial ... except teachers’ unions don’t like the idea of assessing teachers based on their job performance

How did get get from tests that compare different students to tests which assess teachers based on their job performance?

Since "you can, in principle, assess someone’s competence in a given subject area with a test", why not just test those teachers, you know, DIRECTLY?

Perhaps because the author's full of it?
And if course even Linux procfs is not without its surprises. Adding columns or lines was foreseen but some changes are more fun!

Take the evolution in /proc/meminfo that changed the meaning of some of the lines there over time (WTF?), whilst adding others (which was fine, expected, etc.). Of course I want now to include IO cache (that will be reclaimed if I ever needed to malloc) in my system's free memory indicator! Heh you can still get back the old value with this formula, what are whining about?
Thanks, that's ... closer to what I have in mind.

I also agree that the lack of drill-down on tag-based organisation ... kills about 99.9996% of the value. It's sufficiently valuable that you'd expect this to be part of basic implementation libraries by now.

This is fascinating!

A few comments have mentioned the cost to the airline for running the route - the author talks about revenue, not profit - but most, if not all the costs are calculated on time, not distance.

Nearly everything in an aircraft has a maintenance window / shelf life measured in minutes / hours / days / months / years. The JFK - LON route could be 7 hours, or 5 hours depending on prevailing winds.

That’s an extra 2 hours you have to pay the flight crew, run the engines, maybe even an extra meal for the passengers and so forth.

Weather has an astounding affect on how much a given flight will cost, and probably traffic is the next one - hence why landing / gate spots at busy airports are so expensive.

Crew are legally mandated to only work X hours in a given time frame (both active and standby), so if you’re held up in the air or on the ground, especially on a long haul flight - you might not be legally clear to make that flight!

There’s a whole field of dispatch operations for aviation that handles this, and for the finance folks - the financial model for aviation is just subtly different enough to cause a few headaches if you’re not aware.

No doubt, but please don't post generic comments like this to HN [1]. They lead to shallow, predictable, and usually nasty discussions. We're trying to avoid that sort of thing here. It was quite predictable that this post led to a low-quality thread and ultimately a nasty flamewar.

Generic comments usually come from reflexive reactions [2], which tend to be quick and shallow. What we want on HN are curious conversations, which are a different species altogether.

There are many strategies and pacing that exposure therapy can take (the link I provided has several examples); the slow, deliberate process you describe is one of them, as is what's being described upthread.
There's still money on the table for airline operators where routes are concerned. It sounds a bit fringe, but most of these flights take off and land at airports in large cities. International airports are often zoned around industrial centers that are typically set off away from the city core. Coupled with the high frequency of inbound and outbound traffic depending on the airport, commercial flights are excellent candidates for capturing high resolution aerial imagery in near-real time. In many cases, those images can be transmitted back down while the plane is in the air thanks to in-flight internet.

There have been past attempts to harness the passive residual capabilities of air travel for photography, but none have stuck based on the difficulty of scaling such a system. If successful, crowdsourced aerial photography for cartography could add a layer of temporal resolution we just can't achieve with fewer than 500 imaging satellites currently in orbit, and for 1/10,000th the cost of satellite-based imaging. Add on concerns about LEO crowding and the thousands of use cases near-real-time aerial imaging could provide at a fraction of the cost, it becomes an interesting problem to solve.

There are plenty of barriers to this kind of scheme, regulation in particular, that could keep airlines from participating; the first major carrier who does, however, may find themselves with a new multi-billion dollar revenue stream.

Ask HN: Stay in the Job or Leave It?
So I'm a senior engineer and I'm a little over a month into a new job and my gut constantly tells me this is not the right fit. Everything from the social aspect to how the team is arranged to the work that I'm doing.

It is a new team in the company where everyone has been recently hired so it was difficult to get a feel for things when everyone's response was "I've only been here for a few months"

I have a standing job offer at another company from when I interviewed there earlier this year so I could reach out and take that one which since I have friends who work there I know it's a pretty good place.

Here's the rub though. I'm making a ridiculous amount of money at this job. Like retire in a few years money, and leaving to take the standing job offer would be cutting total comp by a substantial (+100k) amount.

What are your thoughts?
Social anxiety spurs from not being popular or commanding a presence in a room, not being in the "in" crowd.

In short it spurs from not being a winner.

The socially anxious person maybe knows at the intellectual level that social wins can be achieved by working the numbers game, but they are too apathetic or nihlistic or scared that their first attempt is going to be a loss which will further depress them.

When you immerse the socially anxious person in a controlled environment you make sure that his first attempt is a Win, and the second and the third and the fourth etc.

And you make them win enough times that they maybe venture into hubris, so that they have a full tank to go into the real world and face the natural X amount of rejections and losses which comes before a win.
I think I should be allowed to talk about the pain this culture caused me.
Your equity is at stake. You have been warned. Perhaps I did not make myself clear. Meeting with the investors is a mistake, your equity in the company is in jeopardy. If you do not make plans to protect it you will lose. I told you to look at Paul Allen. Same scenario, three founders, one almost squeezed out.
I flew most domestic US when I was in the air, and rarely did I need more than under-seat sized.

So? Wouldn’t people that know the cameras are there drive slower than the people that don’t? From a public safety point of view, known cameras are more effective at limiting speed than unknown ones.

Reducing lane width is also shown to be a very effective speed control methodology, that does not require police enforcement.[0]

Or are you concerned about a loss of local and state revenue? Seriously, the use of police for revenue generation, rather than public safety is an open secret among police and local governments.[1][2][3]

Clubhouse rolls out Replay to let users record live rooms and share them later
There isn't a strong justification for pricing it so aggressively when this would drastically decrease their margin. They would be selling their profit to increase market share which is exactly the opposite of their usual strategy especially when demand is high and fab capacity at a premium. They might well be just trading in a higher profit for a lessor if they couldn't make more units than people would already buy at the higher price.
(For me at least) life is too short to wait for the best features to trickle down. I mean, most of the interesting Java 17 stuff was surpassed by OCaml in 1995! That’s a 35 year lag!

People said the same thing about LTCM. They had multiple Nobel Prize winners on staff, literally the people who wrote the Economics and Finance textbooks.

Then a decade later, history repeated with all of the prop trading outfits doing securitization.

It's always the same ingredients: 1) a theoretically sound strategy for taking advantage of some arbitrage opportunity 2) the assumption that positions can actually be liquidated on demand at the prevailing price and 3) enormous amounts of leverage. Then something happens that wasn't accounted for (e.g., sovereign default, counterparty default, etc.) and suddenly the strategy is no longer sound ("in a crisis all correlations go to one"), the liquidity assumption is no longer true ("where are all the buyers?"), and the leverage puts you out of business ("the market can stay irrational longer than you can stay solvent"). People never learn.
Please don't take HN threads further into flamewar, and especially not ideological flamewar, not matter how misguided another comment is or you feel it is.

We're trying to avoid the bottom of the internet barrel here, so each user is responsible for not posting comments that point that way.

My local bike shop ran out of bike models due to the supply chain issues and the only bikes available were e-bikes. Add to this that e-bikes have much higher revenue/margin - most bike shops are converting shop space to sell e-bikes. I wonder if this contributed to e-bike sales?

Also I know a bunch of people waiting for legislation to promote EVs (ie, extend the tax credit) all year (may never happen).

Because they are killing community made solutions by reimplementing the same solution and utilizing community's habit of favoring only MS software that they themselves engraved into that community throughout the years, even if original solution was better, thus closing the circle. They essentially kill the community around .NET themselves because instead of supporting projects like Avalonia, they reinvent the wheel(often ineptly) to ride on that 'Microsoft ecosystem' wave. The only exception to that that I know so far has been Polly that they pulled into .NET Core.

I wish people would stop thinking it’s such a clever take. HN has chosen to leave out almost every engagement driving feature that modern social media is IMO defined by much more than just upvoting and commenting.

It’s social media in the same way my monthly pathetic run is professional sports.
Definitely sounds like you're onto something there. For myself, external validation isn't something I need outside of my immediate family. So that could definitely play a role in how I view social media, and how I was so able to cut it off.

I really enjoyed my e-bike when I bought it in 2018 or so. The pedal assist really felt seamless: you can get to the top speed of 20mph by pedaling with as much effort as it took to get to maybe 12mph on a regular bike.

Unfortunately, the bike being worth thousands of dollars, it was a prime target for theft. My bike was stolen in San Jose and I decided to replace it with a sub-$1000 regular bike.

Great point IMHO. I think the ability to learn these somewhat different languages depend on the experience. Like roots of different trees -- once you groked Asm/C, C++, Python and such, Lisp and such enough, you can get productive in most general purpose languages quickly enough that language learning time will be negligible compared to platform/ecosystem/domain time at least for any reasonably complex domain.

I think more pragmatic question in such situations however, is why the potential employer is requiring $A years of experience in $TECHNOLOGY. For example, why they need someone to be productive from the say day $N and what does it actually mean (for them) to be productive?..

IMHO getting to shared understanding of what drives such requirements can help find a better path forward for both sides.

So far as I can tell, the reason why they're so small is because they implement "everything is a string" literally - so e.g. appending to a list is basically concat. This is good enough as a proof of concept, and neatly showcases just how simple the language itself really is; but perf would be abysmal even by Tcl standards as soon as you get more than a few dozen items per list.

LIL tries to be a minimalist but practical embeddable implementation, so it has basic optimizations like representing lists more efficiently internally. The price, of course, is code size, but also C API complexity.
I find Java's features to be very well balanced, and only make it into the language after they've been vetted and tested in the wild by other languages.

e.g. see their take on concurrency by means of project Loom. No need for async/await and providing separate APIs for sync vs async operations. It has records and sealed types and pattern matching, and is getting destructuring soon.

I don't agree that senior developers can come up to speed on any technology "pretty quick".

I don't agreee that you should not ask for specific senior experience with specific technologies.

It takes years of working intensively with a programming language to really understand it well.

If you are wanting to hire in expertise - i.e. someone who really knows how to get things done with your technology stack - then you MUST select for specific previous experience.

If however you're not looking for someone with expert level skills then sure, hire openly for "smart people who get things done", but in that case, you need to be ready for the people you get to take a good chunk of time to really come up to speed - like six months at least.
+1 for Rider. It’s one of the 2 .NET IDEs I know that don’t suck terribly (the other being the proprietary version of VSCode).

It doesn't even matter if it is a terrorist organisation or not. The Arabs that call themselves "Palestinians" want to conquer and destroy Israel, it is clearly and explicitly written in the Hamas charter, the de facto "constitution" of Gaza. The ones in the west bank want the same thing but they hide behind calling it "the right of return", basically demanding that Israel will let about 10 million Arabs to "return" to Israel, or in other words, conquer it.

So basically Gaza and the Arabs in Judea and Samaria (the west bank) and many other Arab states in the region are enemy entities to the state of Israel, whether they use terrorism or just regular "legal" military operations and political activities. As such, there is no surprise Israel is spying after them like any country would do against their enemies, even if they are not terrorists.

Yes, arguably a better decision than writing it in golang to begin with.
This is essentially the way it works in Switzerland. On motorways there are speed cameras every few kilometers: even with an app to warn you, it’s not worth trying to speed between cameras.
I was at Pinterest from 2014 to 2020, so a total of 6 years. I lead a team and was enamored with the product. I saw hyper growth from a 250 employee company to 3,000. I rang the IPO bell at NYSE.

Was Pinterest shady? No, not at all. Most employees were kind and genuine and trying to do the right thing. Was management and leadership all hyper corporate lizard people? Yes, absolutely. Was it a good company to work for as an engineer? I would say no.

The company constantly suffered from lack of quality technical leadership and as a result the lizard people were in control and the politics were of a company 10x at all times. Decisions were almost exclusively top down. Sound technical ideas were difficult to argue for because shady employees would lie and manipulate the lizard people. The lizard people only cared about self preservation and promotion.

I also think Ben and Evan were heavily influenced by their board (Ron Conway, et all) who saw a billion dollar company and wanted to not rock the boat until exit. It could have been so much more than a cash grab and yet I don’t feel like it ever was or ever will be.
