I actually think focussing on the mass casualty count aspect is misplaced. I don't spend my time at work worried about how wrong things went, I worry about how bad an incident of that sort could have been given a less favourable set of circumstances.

ie. Yes someone got onto the network, but they were dumb and got blocked having done no damage. Is it serious because of the potential or not because of the lack of impact? I claim the former!

As such, the only ratio I care about is frequency of people shooting other people at schools (per capita, sure). On that measure, I am expectant USA is a world leader?
Well, looking at the numbers it does not seem to be that big of a punishment.

By anyway, punishing growth should be valid, IT workers are doing well, the homeless that are to be helped is not like they gonna be hired as software devs at PayPal.

Taxes are nothing but a reallocation of resources and it always has been, and it is the price you pay for living in a society, and it is worth it, you'd rather have the addicted and mentally ill outside of streets one day you might get stabbed by one of them.

Also it is not just about taxes, the gov need to take some drastic measures too.

It’s simple. If you don’t know when your next meal will be, you can’t spare a thought in solving cold fusion.

In order to solve problems you don’t need “more people”. You need “more people with good enough living conditions so that they can work on solving problems”. This doesn’t necessarily means increasing the total number of people. It could go down. As long as enough people went from dispossessed to good enough, that would be enough.
That’s still super useful.

I’m assuming most PR’s are approvable. If that’s the case then this should cut down on time spent doing reviews by a lot.
Another way to look at this is just as an optimization problem. We found a good local optimum and it became too costly to search further.

In the early days of aerospace, the search space was mostly unknown and there were tons of companies investing R&D in a wide variety of designs. Huge amounts of human capital were invested, and as in all things, some designs worked, some didn't. Many companies went bankrupt.

Eventually we find some good designs and the risk/reward of searching the space further just doesn't make sense. Only recently with improved tech and ML/AI + simulation has the cost to search been reduced enough that it makes economic sense to try again.
I don't think it's a question of knowing what an axiom is or how a calculator is implemented. I think it's a question of disagreeing on what "understanding" means.

What does it mean to understand something? Obviously (to me and I presume to you) a calculator doesn't understand anything! It doesn't have the capacity for understanding. Obviously (according to, I presume, feoren and Dennett) "understanding" means something very different, and a calculator is perfectly capable of "understanding" arithmetic.
Hard agree on JS tooling.

This is largely centred on browsers these days (ironically it used to be better for browsers and worse for server, now it's the opposite).

However I'll say two things in javascript's defence:

(1) No other language has yet taken on supporting server and browser environments simultaneously: it's unlikely to be easy for the first.

(2) I have a strong suspicion it'll get much much easier one Node moves past it's CommonJS roots and gets to full community ES module support to match browsers

> The JS ecosystem has six ways to do anything and four of those aren't compatible with your previous choices. Tooling gets extended with endless helpers and plugins to the point where I don't even know what a given command does anymore.

No idea what you're talking about here though. Is this about NPM? What 6 different ways? What tooling extensions? This sounds like vague projection.

> Python venvs and pip are easy enough to understand

If only "understanding" was near enough. Good luck putting together a robust unattended install routine for anything python: does the user have existing venvs, should this script create a new one, where?, how should the user easily init it?, should it be a global init??, autoinit via bash or shortcut via bash alias? What about Elvish? What about fish? What about <Python is a horrible ecosystem, please don't get me started on its ills>...

Terrible article. For one, how do they even define debt?

Long term debt only? All liabilities?

Whether to go to an Ivy or not depends on what you're looking for.

I went to Iowa State for undergrad and then did a masters at Princeton immediately afterwards. I greatly appreciate both schools.

At Iowa State, most of my classes were easy. But I pushed myself with the sheer quantity of classes I took. I was super involved in extracurriculars and still went out multiple nights per week. I was one class short of a double major and I spent a semester abroad. My only regret is not spending 2 semesters abroad. It was an incredible time.

Princeton also did not disappoint. The Graduate School is for sure the most intellectually rich environment I've ever been in. Academically, it was far more demanding, and pushed me to a much deeper level of engagement with my studies. I also know that Princeton would have been a way too intense environment for me at 18. At 22, it was what I was looking for.

I also went to NYU for another masters program, which was in many ways even more different from the first two universities. Some people just go there to be at university in NYC, but it's a sprawling school with tons to offer and feels physically and socially much more integrated with the real world than campus-centric universities.

I don't think there's a one size fits all answer for whether to go to Harvard or any other school.
You claim this, but have you ever been in that situation before? Backing up on a road with traffic is extremely dangerous, and I'm not sure I could do it while under the stress of an emergency vehicle situation. There was no room to U-turn (if there was, the fire truck would have been able to get through), and I'm guessing parked cars on the side of the road prevented any kind of "moving further to the right".
It's a pretty big stretch to tag Russia as an ally of the US in their invasion of Ukraine.
it seems these teams lack(ed) the drive to consciously change.

meetings should have conclusions (action items based on consensus, which are commitments from all members) and it's a typical team dysfunction when members don't honor commitments (someone doesn't do something and then others don't bring this up to hold each other accountable)

if the team is so dysfunctional that it just does the same thing over and over again while constantly promising to change then it should be broken up before the members themselves start to suffer the psychological toll of this cognitive dissonance.
Some people say that's how you should aways answer. Someone asks "how are you" and you should answer "fantastic!" or something similar.

You say it and you will start to feel it, so the theory goes.

I'm not sure it works. I usually say "I'm good, how are you?" and I think the over-the-top replies sound phony, but I haven't really tried it.
> To each their own, but I think it's important for people to get out of their headspace and see things from a more general perspective as well.

What makes you think those of us who enjoy living in the area haven't made the conscious choice? There are good reasons I chose to live in the urban parts of the SFBA, just like I presume there are good reasons several of my friends are happily running a household in Seattle, Austin, Chicago, Brooklyn, Columbus, or pretty much any other part of the US.
How about for soft targets like schools we start by locking the dang doors, securing the property and screening everybody that comes and goes?
> Why do any intelligent consumers believe they can be relied on?

Because they know the reason for all those regulations: we started without them and people had such a bad time they decided restrictions on businesses were an improvement. And they were right, in all of human history there probably hasn't been a time when commercially produced food was safer than today.

> If the government doesn't enforce labels, sensible consumers can pool their funds and pay laboratories to analyze the food for them

We can do that either way, and it is in fact done.
I think if the average person thinks the goal for making it in life as a 7 figure comp, 99% of people will never be happy.
Yes, I have backed up for emergency vehicles in the past. (and gone through red lights if necessary and pulled all the way off on shoulder and crossed double yellow line... - all of things an bot might not have done). I've been driving for 3 decades, most of it in an extremely congested area, so it happens.

There might have been room to U-turn for the automated vehicle. Bit of ascii art here

===DUMPTRUCK==

BOT===FIRETRUCK

Bot, in that situation can U-Turn. Perhaps maybe back up a metre or two first (let's pretend there was another car or two there but there was a metre or two to backup - although if bot slowly backed with hazard lights on and honking a car behind them hopefully would have too - maybe no U-Turn necessary). Yet there would be absolutely no way for a (large) firetruck to get through. Point is, require's a human's full awareness of world and flexible thinking and when it is appropriate to break the rules (rule of arriving at destination, rules of road conduct). These bots still don't have the neural complexity of a crow, much less a human (probably not even that of a goldfish really). They are ok at the predictable but that's it.

I have no doubt they'll get there eventually, at which point we might be having another ethical conversation about what a AGI should be allowed to do with its life, but they aren't there yet...

Do you know about the prusik knot, and the corresponding practise of prusiking?

Works on the same principle as the taut-line hitch. You can hang your weight in the knot on a vertical rope indefinitely. If you can then find a way to unload the knot, you can slide it up the rope and then put your weight on it again, slightly higher up than before.

So how do you unload the knot? By loading another of the same knots! So you alternate between loading and sliding the two knots, making your way up the rope with comparatively little effort and comparatively high security.

It's quite amazing!
how did you estimate hours? do you mean that the team estimated "story points" and it was so precise and the team was so good at meeting the per-sprint point load that it was basically a nice hour estimate? or did you estimate hours directly?

You can always deduct the vehicle if you own a business. I have a small business that generally grosses only a few thousand per year, but I deduct all business use of my personal car.

The difference, IIRC, is that instead of amortizing the cost over years, IRS Section 179 allows you to expense the entire cost of a 6,000+ lb. vehicle in a single year. So if you own an Escalade like my neighbor, that's an $80,000 tax deduction in one year.

It's certainly tempting and I'll probably do exactly the same thing once my business makes enough income for it to make sense. The tax code is a thing: use it to your advantage.
And each department (and sometimes class or professor) has their own policy about whether they ever grant an A+.
It's called 'State Street Dodge'. You play a bicycle messenger in 1990s downtown Madison, Wisconsin, rushing important legal documents across the isthmus. You ride a super sweet freestyle BMX bike, and you rack up points for doing tricks, jumping beer truck ramps, riding up walls, and dodging the ever shifting throngs of college students, hayseed tourists, and harried bureaucrats. Bonus levels let you switch to skateboard, Rollerblades, and fixie. Soundtrack is awesome. Lots of Easter eggs.
not necessarily. One of the things Ive come to understand is that economic efficiency is not always the top priority. In many cases people want reduced variance. In return they are ok with less efficiency.

Economics can predict the outcome, but cannot make a value judgement between two options.

I used to think some people were irrational (especially when they disagreed with my logical viewpoint). It turns out that everyone is irrational, they simply have different opinions of the relative priority of values. For example it might be worth it to them to trade off long term economic efficiency for short term reduction in variance.

Nationalized health care, social security, and rent control are all examples of policies that reflect this value system.

"Freedom" is not a universal value. In fact many people are willing to trade freedom for security (or reduction in variance). They are not wrong or bad people, they just have a different opinion of priorities.
Good point about the derailleur, I hadn't thought of that!

i don’t believe that that assumption will hold up

in case you don’t read the whole thing:

“In other words, the rational players disguise themselves as irrational; they make others believe they are altruistic, thus forcing others to play cooperatively. Therefore, this approach is also well known as “crazy perturbations.””

Thats a good example of what that researcher discovered back in ‘05
>It just needs to be 1% better than human drivers. If the net result is 1% less tragedies - sign me up.

Say you have a child and want to send him to school, would you chose

1 drive him yourself, knowing you have 10 years of experience with zero accidents and you are responsible and care for your child

2 use a lottery that will give you a random driver, could be a 16 years old teen with 1 day experience, could be a 80 years old elder or a drunk or tired dude or a super driver

3 use an AI , is better then the drunk dude , 1% better then the teen but worse then you and much worse then a professional driver

I am curious why would chose 2 or 3 if 1 is an option.

Again, the ozone layer isn't "solved." It's "recovering." Go ask any reasonable person in Australia or New Zealand if the ozone is 'solved.'

We haven’t fixed the problem[1], although I agree there is some worthwhile pat-on-the-back for fixing the cause. The ozone hole is still there decades later, and will be there for decades more.

In New Zealand, they are affected by the extra UV radiation, and strong sunblock can be important.

The effect by UV should give us more understanding and sympathy for countries that will be drowned by climate change, even though our government isn't doing jack shit.

[1] NASA website says “Scientists have already seen the first definitive proof of ozone recovery, observing a 20 percent decrease in ozone depletion during the winter months from 2005 to 2016.” “Models predict that the Antarctic ozone layer will mostly recover by 2040.” Also see synthetic image of 2021 hole: https://www.nasa.gov/feature/goddard/2021/2021-antarctic-ozo...

Government management of the economy can do better than private management. Private management can do better than government management. The idea that either thing has been disproven is what is preposterous. These mechanisms don't predict success or failure by themselves.

> (1) No other language has yet taken on supporting server and browser environments simultaneously, it's unlikely to be easy for the first.

ASP.NET has allowed you to write purely backend code and add interactivity forever. Of course you can't get around JS in the front-end, but a mix of backend and frontend code existed long before Node got any popularity.

> (2) I have a strong suspicion it'll get much much easier one Node moves past it's CommonJS roots and gets to full community ES module support to match browsers

I agree. Then again, the Node ecosystem always seems to be moving from one standard to another.

> Your playstation, on the other hand, requires you to buy two or three games

Source? This has not, to the best of my knowledge, been true in console production for a very long time.
Very relatable story. I think I've had similar experiences throughout my life. I never fit the academic mold very well. But whenever I was given the freedom to explore a topic of interest without a lot of pressure, I think I always excelled. It was fortunate that computer programming classes at my high school were basically like study hall. The teachers didn't make you do anything. That meant that the handful of us who were motivated out of personal interest could take things as far as we wanted to go. We weren't constrained by a curriculum. When I got to university, I felt like I was way ahead of the game and had already learned a lot of the things that were covered in freshman comp sci courses.

I think I understand in theory what the point of grades is. It's hard to imagine a perfect way of deciding who gets access to limited opportunities and who is best fit to take advantage of them. However, I know from deep down that my life would have gone very differently if I hadn't been given those critical chances to wander. Competition can filter out the people who are less innately talented, but just as often filters out people who just don't like having to talk over everyone and fight for everything all the time. If you're just a shy kid or are starting out with a weaker self-image for some reason, you can fall to the bottom of the pile really quickly regardless of whether or not you're smart or worthy of good things in life. That's why I tend to think a certain amount of grade inflation is alright; because it unlocks hidden potential in people who don't look the part. Maybe in a sense it also penalizes people who game the system by chasing grades while missing the real point of getting an education.

PS5 market is definitely bonkers.
After sitting through some of the crazy queues on the playstation site and giving up on direct to consumer I did manage to score one, but it was tedious for a few days getting hammered by every twitter notification from a few of those accounts that watch and post when stock becomes available.
When I did land a unit, it wasn't without a price shock of its own as GameStop was selling as bundles. So, yeah I ended up with maybe a couple of games that I would rather not have bought up front and they were pretty close to full retail price.

This was all very, very frustrating. Sony knows I have years of history with them going back to PS3 era. They could throw me a freakin' bone and let me reserve a spot in a queue, even if it was in agreement with a 3rd party retailer - I'd be cool with that. They could manage this situation so much better.

//
Not to mention that once I got my unit, the storage evaporated almost immediately. PS5s hold about 5 or 6 "large games" at a time!
Thank you for the valuable feedback; much appreciated :+1

GPUs are weird.

HLSL and CUDA have C-like syntax, but underneath the syntax these things are very different from C.

On GPU almost nothing has an address, there's no stack, no malloc/free, no files or printf, and every instruction runs on 32+ threads in lockstep.

This is a spooky narrative, but the rent seekers can't be the majority. My understanding is that many Californian real estate markets are kept artificially tight due to various forms of NIMBYism.

If renters become the majority, it's suddenly no longer viable to limit new housing through regulation. Markets are nowhere near the fundamental limits of homes per square meter of the state that's good to live in.
