Kipling is fantastic. Read the whole poem: https://www.kiplingsociety.co.uk/poem/poems_copybook.htm

As I pass through my incarnations in every age and race,
I make my proper prostrations to the Gods of the Market Place.
Peering through reverent fingers I watch them flourish and fall,
And the Gods of the Copybook Headings, I notice, outlast them all.

We were living in trees when they met us. They showed us each in turn
That Water would certainly wet us, as Fire would certainly burn:
But we found them lacking in Uplift, Vision and Breadth of Mind,
So we left them to teach the Gorillas while we followed the March of Mankind.

We moved as the Spirit listed. They never altered their pace,
Being neither cloud nor wind-borne like the Gods of the Market Place,
But they always caught up with our progress, and presently word would come
That a tribe had been wiped off its icefield, or the lights had gone out in Rome.

With the Hopes that our World is built on they were utterly out of touch,
They denied that the Moon was Stilton; they denied she was even Dutch;
They denied that Wishes were Horses; they denied that a Pig had Wings;
So we worshipped the Gods of the Market Who promised these beautiful things.

When the Cambrian measures were forming, They promised perpetual peace.
They swore, if we gave them our weapons, that the wars of the tribes would cease.
But when we disarmed They sold us and delivered us bound to our foe,
And the Gods of the Copybook Headings said: "Stick to the Devil you know."

On the first Feminian Sandstones we were promised the Fuller Life
(Which started by loving our neighbour and ended by loving his wife)
Till our women had no more children and the men lost reason and faith,
And the Gods of the Copybook Headings said: "The Wages of Sin is Death."

In the Carboniferous Epoch we were promised abundance for all,
By robbing selected Peter to pay for collective Paul;
But, though we had plenty of money, there was nothing our money could buy,
And the Gods of the Copybook Headings said: "If you don't work you die."

Then the Gods of the Market tumbled, and their smooth-tongued wizards withdrew
And the hearts of the meanest were humbled and began to believe it was true
That All is not Gold that Glitters, and Two and Two make Four
And the Gods of the Copybook Headings limped up to explain it once more.

As it will be in the future, it was at the birth of Man
There are only four things certain since Social Progress began.
That the Dog returns to his Vomit and the Sow returns to her Mire,
And the burnt Fool's bandaged finger goes wabbling back to the Fire;

And that after this is accomplished, and the brave new world begins
When all men are paid for existing and no man must pay for his sins,
As surely as Water will wet us, as surely as Fire will burn,
The Gods of the Copybook Headings with terror and slaughter return!
> Cache coherency ensures that the behavior is correct, but every time a cache is invalidated and the same memory has to be retrieved from main memory again, it pays the performance penalty of reading from main memory.

1. First no. If any such rereads occur, they will be from the LLC (last-level cache, or L3 cache for Intel/AMD CPUs).

2. Second no. IIRC, modern caches are snooping and/or directory caches. This means that when Core#0 says "I'm changing cacheline X", Core#0 knows that Core#1 has it in its L2 (or deeper) caches. So Core#0 will publish the results of that change to Core#1

3. The examples they gave are missing read/write barriers, which are rather important. #2 will only happen during read/write barriers. That is to say: your code is memory-unsafe by default. If order and cache-invalidation matters, you actually need a barrier instruction (!!!) to make sure all these messages are passed to the right place at the right time.

---------

For better or for worse, modern CPU design is about doing things thread-unsafe by default. If the programmer recognizes a problem may occur, it is the responsibility of the programmer to put the memory barriers in the right place.

This is because the CPU is not the only thing that can reorder things... but also the cache system... as well as the compiler. So memory barriers inform the compiler + CPU + cache system when to synchronize.

The original Netflix article is more precisely worded.

> This consistency is ensured with so-called “cache coherency protocol.”

With a link to MESIF (F for Forwarding state, which is one such protocol / way to share L1 cache info without going all the way to LLC or DRAM)

I'm pretty sure that GPUs actually invalidate the cache dumbly, without any MESI / MESIF (or whatever). GPUs are actually really bad at these kinds of ping-pong operations and synchronization... preferring thread-fences and other synchronization mechanisms instead.

------

That being said, I think the blogpost is a good introduction to the subject. But note that its a bit imprecise with some of the low level details. I guess its correct for the GPU-world though, so its not completely inaccurate...

-----

The original Netflix article has an even more difficult problem revolving around Java's Superclass cache and how it is affecting "true sharing" of caches. I'm not very familiar with JVM internals, so I lost track of the discussion at that point.
It has been evident for some time that boys and men are struggling. Its the same old story. In this country we like to take up one group for special consideration -- like girls -- and at the same time insinuate that the solution is to blame another group -- men and boys. Then eventually we realize how much trouble the other group is in. That is where we are now. For the most part, girls are flourishing and boys are not. Reeves decided to make a book out of this, where a long article might have been sufficient. And, like the typical "social problem" book he has many chapters about the various ways boys and men are behind or not making progress, and then ends up with a few suggestions on how to address the issue. Could we find a better way? How about thinking about social policy in a new way that focuses on programs aimed at raising up all people and avoids pitting one identity group against another?
and that's why it is a historical account
They took the money and used it to survive as a company to build more electric cars, which is the whole purpose of the credits.
He added some context specifically about that note:

It would be interesting to see the % of profit over time from regulatory credits, which appears to be what the author is focusing on.
We need 3D slicers, surely someone tried to make AI for that already ?
Except murder is always illegal and immoral. Taking someone's money is only illegal and unethical if they did not consent. Huge difference

Lack of a set type is just bizarre to me
And the name just rolls off the tongue!
lol, “don’t worry, I hear people survive just fine without their arms or legs. We can endure a little more frostbite just fine”

This shouldn’t be the bar. The bar is avoiding a “global catastrophe” ie mass migration and the start of resource scarcity. All of which will occur significantly sooner than “global collapse”. It definitely requires more aggressive action early.

Obviously keep using oil and gas so we don’t shut off anyone’s heat or food supply tho. Otherwise, everything else including higher costs (ie total shit for many many people) should be utilized to avoid catastrophe.
> if you want to compete in the job marketplace, or to be considered on dating apps, or just in general to participate in society it's almost a necessity to compare yourself to your peers. Obviously we should all be like the Buddha and not be drawn to comparison but it's a hell of a lot easier to do that when you're the guy on top.

This is so perfectly and lucidly expressed that I'm replying to it just to "bookmark" this quote.
> I'm struggling to find any analogous situation to a single verified breech of trust destroying billions of investments in the gas sector of Russia.

Is that context or just an admission that he's wrong?
The expression is "hedge its bets" and that doesn't make sense in this context.
There's been a lot folks suggesting that twitter move to the fediverse/activitypub. If he did that then, yes, he would be on mastodon and twitter would become the largest mastodon server overnight.
"Nobody goes there, it's too crowded"
That was at one point true, but hasn't been true for at least a few years.

Heroku could have gone back to that i suppose, instead of getting rid of free dynos entirely, but they didn't.

Still... I think you could basically only run one free dyno per account 24/7. I am curious if they somehow fit their entire production in one free dyno, or were somehow splitting things between multiple accounts, or what.
Yeah, exactly. She chose to ignore market substitution assumption, but there is no rebuttal to it.

What does it mean to observe the event horizon?

LIGO has been able to confirm theoretical properties of the event horizon. The EHT has imaged a black hole, which effectively images the event horizon.

Is there a reference for that?
> Listen, weird nerds and $8 blue checks, I don't care about the 3rd Quarter of this year. I'm talking about the history of the company, its foundations and how it arrived where it is now. Which is a story most people clearly didn't know.

Wow, does he seem salty when called out. You can't untangle these profits from the car business. The credits won't exist without the cars.

The credits are not a magical widget that they are selling independent of the cars.

I already have over 4 years of professional software engineering experience (mostly backend web development). Before that I've been coding as a hobby for like 8 years. I'm pretty good with C, python, and PHP, though I'm familiar with plenty of other languages. I also know a little bit of Haskell.

For a person like me, is HTDP worth it? I had started with it previously but I found it a little boring. But I know the book is well regarded so I'm wondering if I should take another shot at it.

Or should I go straight to SICP?
The linked tweet is:

>Thread time. Here's the thing about @tesla It's not a car company. Tesla is a company that has to make cars in order to sell its real product: Emissions Credits.

It uses 'is' not 'was', in three different places. In English that means they're claiming it's currently the case, not a historical account like you're mistakenly thinking.

What makes you think it's a historical account?
> But moreover, as you mentioned people want a sense of community without and of the accountability that Church asks.

Do churches ask for accountability or conformity?

> You want community without the worshiping God part. You want total freedom without guilt. And you want everything you do to be accepted without judgement.

I believe you are strawmanning here. People who don't attend church experience guilt and have a moral compass likely in equal measure to churchgoers. The judgement that people wish to avoid is the kind that denies LGBTQ people's humanity, among other issues.
I believe this is in line with "contact theory", the naive version of which Putnam's statistics seem to refute. Unsegregated areas usually have lower trust, at least in the short term.

But.

Categorizations change over time, and many lines that used to be important no longer are. So he holds out hope that the same blurring can occur to the lines that matter today.

He suggests that the formation of higher identity -- perhaps a civic nationalism like we see in Ukraine -- is the way forward. The main positive example he can point to that spans current lines, and not obsolete ones, is the Army, which arguably does just that. To a lesser extent, he also mentions the Catholic Church, which -- like Islam, I will add -- provides a higher identity that spans ethnicities.

I've heard some other authors make similar calls, e.g. Francis Fukuyama.

I am an avid strong towns reader. However I live in inner city Portland in the exact neighborhood strong towns wants everywhere and street racing is a huge problem here which has led to homicides.

Blaming this on stroads is a dangerous politicized oversimplification.
Most of Elon Musk's companies depend on government subsidies or contracts in order to be profitable. Currently the only one that doesnt is Twitter so we'll see how long it survives without tax payer intervention.
> In a decent sized building I bet you’re not the only lonely person.

Why do self-admitted lonely people not jump at every chance to be social? I think therein lies the rub.
What? Any port in Africa would suggest otherwise. The Belt and Road initiative is not done for charity. When a Chinese state owned enterprise wins a mining contract in a country that is heavily indebted to the CCP you think is is mutual aid? The CCP has put the squeeze on a lot of countries recently for clear political reasons.

Victims are not always blameless. In this instance, victims are well informed about the consequences of borrowing & choose to consent. One could even argue that creditors who do not get paid are victims - they're the ones who provided funds to the borrower for them to enjoy their goods

Obviously, one should not blame a murder/rape victim
I believe you are talking about this book.

That was the agreement required to get the little states to join the union.
Part of the home ec curriculum (at least when I took it a long time ago) is personal finances; one thing that we learned in high school (before being able to get a credit card) was that carrying a balance on a credit card is really expensive in the long run.
I wish. It’s not just Gen Z though - look at average amount saved by household, or average amount of incoming going to savings, or average household credit card debt. Average credit card balance recently had the highest leap in 20 years.

It’s all really, really ugly.

It’s interesting though… if historical parallels return. When a man owes little money, the bank is in power for the relationship. When a man owes a mountain of money, he’s in charge. Banks can’t magically force customers to pay what they don’t have - and politicians won’t accept having tons of people on the street with their assets seized. I would see the higher credit card utilization statistics as something to panic over if I was a bank. It crosses into potential en-masse default territory.
I live in inner city Portland where street racing is a huge problem. I live in an area designed for humans.. the area was great until the lockdowns came

Lockdowns of any kind are not designed for humans.
It really does. I believe it's really bad for society as a whole.

I know not everyone agrees, but as a Muslim, it's really tough for me thinking of starting a business without loans from a bank. I'll eventually have to find an investor, or better save up enough to get started slowly.
Don't mean to sound condescending but I am fascinated by this fascination.

If you move to SEA your cost of living might be as low as $500/m depending on the frugality and living standards. Its not for everyone obviously due to various life circumstances (caring for relatives, wife with kids, illness). But for the young, single and free there is a world out there that doesn't require you to have a 300k/y job to survive in upper Manhattan and service the car / house loans :)

I wish people explored the world a bit more. It really does give perspective in terms of how the rest of 99% live outside of our tech bubble.

Fast overtakes might rarely be registered because those are short lived.
> Spending money you don't have is being financially irresponsible, regardless of whether it's through credit cards or some other equivalent.

Meh - I've spent money I didn't have when I was younger - life is short, what was a lot of money back then is irrelevant to me now and that's expected (you earn more the further you go in your career). I can't go back to twenties now no matter how much I saved back then.

I highly doubt many high school students would care or even pay attention to such a subject.

I am not saying teaching the subject in school is bad idea nor should it not be required schooling. I just think this solution is too utopic.

Keeping people financially illiterate makes a minute subpopulation of the finically literate very wealthy. In other words, I think the system, albeit vile, is working as intended (sadly).

Modern pcbs cannot be compared to garage shop pcbs. No one in a garage is going to be making me blind/buried/stacked micro vias, controlled impedance traces, exotic substrates etc. there are a handful of proto shops in the USA that can do it but the vast vast majority is in china. For large scale pcbs needed for consumer electronics I’m not sure any domestic supplier could meet the demand. I don’t know the situation in EU but it’s probably similar. Don’t even get me started on flex pcb vendors…
I just upgraded with basically one click after I clicked on the alert banner warning me I had to. In my case from a pg free to pg "mini" (I was already on a cheapest-but-non-free dyno, which will change it's name but still be the same otherwise).
Not sure, it depends on what the numbers look like going back to the founding of the company. Tesla probably wouldn't have survived in the past without the credits, but as others in the comments noted the point of the credits is to enable companies selling EV's to survive and grow during their difficulties in the switch to EV's. So I definitely wouldn't consider this a mark against Tesla, the credits are doing what they're supposed to, to an extent.

He's lying.

The first tweet reads:

> Here's the thing about @tesla It's not a car company. Tesla is a company that has to make cars in order to sell its real product: Emissions Credits.

Nothing in the past tense or about history. He's claiming that Tesla is such and such right now.

He's hiding tweets in the replies that call him out. And is saying:

>My first "Added context" on any tweet is of course from Elon stans.

That’s why I mentioned reviewed code. The original FreeBSD code which sparked the drama wasn’t reviewed.

And honestly some of the issues that were there are not something preventable by limiting oneself to even 50 LOC. I don’t want to speculate how they came to be though. It’s really baffling.
For those who don't know what a street takeover is, from the article:

Suppose that I use a hardware wallet. Where do I hide the seed?

In '09, I had a "year off" after the Netapp layoff and the job market wasn't exactly hopping.

I had WARN and severance that would last me all summer, fall, and a bit into the winter before I ran out of that.

So, I spent all summer and fall and a bit into the winter (the thing that finally had me head to my parents' house was a snow storm from the Dakotas heading east in October) driving, hiking, and taking photographs.

There were some hikes that I did then (petroglyphs at Ozette, Ramona Falls on Mt. Hood) that would be much more challenging now that a decade and a half have passed. My endurance for driving has also gone down - I noticed this coming back from Dickinson, ND after the eclipse of 2017 (I really should have gotten a hotel room in Minneapolis) compared to the last leg of a trip from Twin Falls, ID to SF in '08. I can't do 10h drives anymore like I could when I was in my thirties.

And so while there's the "a year off when you're 25 vs retire earlier in your 60s" debate, I would tend to argue for the "when it's a question of experiences to be had, regrets are often the more costly side of the equation when looking back on it later in life."

Also note that not everyone has the same life trajectory of a family and kids and grand kids to look forward to in their later years. For me (single, no kids, on the far side of the half way point between 18 and 81), I am very glad that I had my great road trip when I was in my 30s rather than trying to do it when I was retired.
