Thanks.

I noticed they have a public repo with a tool that manages a way to download the spark code base.

I'm guessing without a token you can't access whatever code that public tool pulls down, meaning you need an active token to get future updates of the code base? Pretty cool system if that's the case (there's motivation to keep your purchase to receive updates).

I'm not asking to try and rip him off. I was just curious about the mechanism of protecting the download. Sounds like the only real difference here is the download is done over a command line tool instead of a web interface. Other than that, it's no different than serving a protected file?

Cloud Run/App Engine PM

Run and GAE run directly on Borg (which is the shared infrastructure that underpins all Google services, including Cloud products), rather than on VMs.

(Shep|reindeer)herding and hunting dogs are common for the Sami people in the country side, while I don't see any reason for dogs to be less common for the average populace. Some would have a practical use too, to protect from foxes and (lone) wolves when possible, and of course, some are kept as pets.
Another thought that adds to this viewpoint: slightly more dangerous playgrounds teach kids how to play more safely, and they grow into adults who also know how to play responsibly. Kids who never get a chance to develop good balance (with the immediate feedback of bruises and scrapes) will not be as good at avoiding falls and other physical dangers as those who have good balance. They also won't know their own physical limits, and won't know which activities are too dangerous.

GDC 2019 was a few months ago, but it took a while before AMD posted the slides of this particular talk to their site.

AMD's yearly GDC Ryzen talk always goes into super-low level details and processor specifics for their CPUs. This year, a particular highlight is the "Data Path" slides. There's a lot of information on the Cache <--> DDR4 link, but page ~21 is the best summary if you want to skip somewhere good.

> hypocrisy of Christians who don't support gun control

I don't see how the two equate to hypocrisy. A friend of mine (a Christian) is strongly opposed to gun control. He has a concealed carry license and carries everywhere, because he wants to have the means to protect himself and his loved ones from an active shooter, if necessary. He cites "if guns are outlawed, only outlaws will have guns," and feels personally affronted by gun control legislation.

That, and he prays regularly for others. I for one would not accuse him of hypocrisy on that basis.

You can’t stop it.
Mostly the performance characteristics. A virtual machine presenting as a machine needs an operating system to be useful. Most operating systems have long-engrained assumptions about the nature of the world, such as:

"There is a time when I go from power-off to power-on, and it is rare, so I may perform expensive operations then to amortise their cost over running time".

or

"While running, time does not skip and hardware does not change".

The practical upshot being that the OS needs to be booted from scratch in a number of scenarios.

But it's not the OS that provides value. It's a means to an end, and that end is to run software. Most software written to run on OSes also have engrained assumptions, such as "I will come to be launched on a fully-booted system".

Containers move the virtualisation up from hardware to the OS API surface. Because the cost of booting is now amortised over all containers running on the system, the original assumptions of both OS designers and software designers become, approximately, true again.

So you're right, we came full circle, but not to a point that means "use fully-dressed VMs again".

> From that point, I slowly began to understand that people in consumption-based societies assemble their identities via stuff, and become very emotional when those identities – and that stuff- is discarded in ways that don’t match their values. Over the years I’ve come to the conclusion that consumers actually care more about how their stuff is discarded, than how it is manufactured.

Part of the problem is that so few bother to get rid of what they no longer use. They pack it around with them, unable to part with utterly useless things.

The interview mentions Japan. In this context, it's interesting to contrast Marie Condo's Tidying Up. She talks at length about how emotions play into our inability to toss things out.

Her system is simplicity itself. Begin by dumping all of your crap of a particular category into one big pile.

She describes the shock most of her clients experience after doing so. If you've never tried this yourself, I can highly recommend it. It's staggering how much crap even tidy people accumulate because it's so often spread out in various places.

It's not hard to understand how packing crap like this drives an insatiable urge for ever bigger houses and cars. You need more room to accommodate your every growing collection of crap.

The environmental consequences of this behavior are staggering. I'm not sure whether this is is something new or not, but it's plain as day that houses, cars, and yes people are getting bigger. Look inside those houses and cars, and you're likely to find an accretion of crap whose contents even the owners can't recall.

So there's a reluctance to toss things out, and there's a real lack of understanding about how much crap we actually have. Sounds like a first world problem to be sure, but one with bizarre emotional/psychological/environmental angles I don't think have really been explored that much.
"What do you mean I can't Uber eats here?! How do people even eat?"
Great is the enemy of good.

Nowhere is this proven stronger than in alternative energy.

Nuclear is proven, practical, and we have technological benefit of decades of experience.

If finding alternative energy was really necessary (and thanks to the abundance of coal and the tragedy of the commons, it won't be for ages), there wouldn't even been a discussion.
Reimplementing system calls is non-trivial, especially ones that have complex interactions with others (for example, the system calls related to process management). How do you prevent errors when translating this, and how do you implement features that ostensibly require calls to the OS anyways?
These are some factiods I've been accumulating on Nuclear, which I'm still trying to refine and learn more about, so any corrections on this would be appreciated if I'm factually wrong:

1) Thorium is safer but isn't being used effectively. Mostly because development of Nuclear power coincided with nuclear weapons, and Thorium can't be used to make weapons.

2) We can re-enrich nuclear waste but don't because of regulations. My understanding here is that the waste product becomes much smaller.

3) We have no clue what were going to do with all the solar panels after we're done with them either? They contain a ton of lead. They also produces something like 1000x the waste mass as nuclear. Don't get me wrong, I'm not saying we shouldn't go this route, but I AM saying that we really need to have a wholistic well thought out solution rather than knee jerk fear.

4) If you compare CO2 emissions of France and Germany, one who went all in Nuclear and the other who went all in Solar/Wind. France has significantly dropped their CO2 emissions.

5) Gas power plants are typically used to supplement the downturn in supply of Solar/Wind. Nuclear is a terrible supplement for this.

Now Opinion:

I think that it's safer in the short term (assuming Global Climate Change for deniers out there) that Nuclear power is a better option for large scale reduction of CO2 Emissions until we have repeatable large scale solutions with solar/wind that are both recyclable and work at night / when wind is down. Because to support Solar/Wind Germany has had to rely on Gas power plants to supplement their gap in supply. Which they sell the excess to their neighbors instead.

As I stated above, I'm still digging around forming an opinion on this but it's why I'm at where I am now.
A friend of mine designs playgrounds for kids, and is very good at it (his designs win 90+% of the competitive bids he enters).

He's also worked hard to put in place a playground safety inspector certification system over here.

One of his core ideas is that there are two types of safety: subjective safety and objective safety.

For example, kids quickly learn that falling from a height is painful, and experiences such as that teaches them how to evaluate their own safety when say climbing. This is the subjective safety.

However they're usually not going to be able to correctly evaluate the safety of climbing a playhouse where they might get their head stuck between two planks because the opening between the planks were just right for their heads to fit, but not their bodies. Or that the hood drawstring in their jacket can get stuck in small wedges and openings, especially dangerous near slides. Such issues go under the objective safety.

Now, his point is that you can make playgrounds which are objectively very safe, without making them any less exciting. Part of the excitement comes from allowing the kids to explore their subjective safety boundaries, but a lot comes from the design itself.

He often works with one of the major suppliers of playground equipment on their new designs, but a large part of his secret sauce is how he places that equipment on the playground. Many playground designers (which at least here are mostly landscape architects) seem to just put one piece there and another over there, without giving much thought to facilitating the flow of spontaneous play from one piece of equipment to the next.

Anyway, he could explain this a lot better than me. I just help him out with some presentations and such every now and then.

Ask HN: Is anyone else tired of programming?
Sorry if this is just complaining to you. I've been thinking this way a lot lately.

I've been programming professionally for eight years. I just have so little interest in doing anything with computers anymore. For me programming has become a continuous stream of problems. For example, if you try to install software A you'll run directly into something like "error 12394: can't read stream. blah blah blah" and then you have to Google that and eventually find out it's because SQLite isn't installed or it is but it's global. You know, stuff like that. Maybe you get a mystery error that you just have to Google your way through and by the end you've tried so many things you don't even know if it was JUST the last thing that fixed it. Stuff like that.

But maybe what I find the most frustrating is the subjective nature of what "good" means. Like it's all in head-space. You can write something absolutely brilliant and no one has any idea unless you sell it to them and at that point it's just about selling it to them. For example, I've been doing woodworking as a hobby and with that there is a physical object that people can see. If you don't do your cuts right it's obvious. People can see. Your work speaks for itself.

I could go on but basically, programming has changed for me. I used to feel being good meant knowing the most and at some point the people who knew nothing changed what the important things to know were and it's been backwards ever since. I'm just tired of sitting behind a computer screen all day. All day! I swear I'd rather plow fields but that pays like $4/hr.

Anyone else feel like this? Just looking to see what like minded people have to say about this. Thanks.
Even if they did, what good would it do?

I was watching some kids in our local playground climb pretty high in some of our local trees and wondering whether this a good idea, and came across this writeup on risky play: https://www.psychologytoday.com/us/blog/freedom-learn/201404...

Modern parents who keep up to date on the parenting zeitgeist will have been exposed to the complementary idea to risky play that instead of saying "Be careful!" to a kid, you can instead ask "Do you feel safe?", helping emphasize what it is that you actually care about and helping your kid develop their gut feeling for what is/isn't a good idea. (See one writeup of this at https://rhythmsofplay.com/get-outside-connect-climb-a-tree/ but a Web search for ["do you feel safe" "be careful"] will find lots of people saying essentially the same thing).

I wonder what the zeitgeist will say in 10 or 20 years - given what everyone is thinking now, where will they be in a little while when we've had a chance to reflect on what we've tried and how it's gone?.

Finally, Disney is not what it used to be, it's now mostly an entertainment company. They have 0 understanding of these things, it's way beyond their capacity. It's a regular public company without founder/visionary and I can't ever see a board approving this.

Google - this would be a company for which it would be outlandish but still within reach, i.e. they have (had?) 'moonshots' - those heady founder-backed 'change the world' projects which are part of how companies winning the current 'visionary narrative' get to spend their money.

That's all gone; fortunately Bezos can spend, and it's SpaceX's business to do that, not a side-show, so they'll be around. And the Virgin billionaire as well.

Edit: I should add - Disney is firmly an entertainment business, they are effectively a Hollywood Studio, mostly like any other. For anyone with any exposure to this business, it seems abundantly clear how out of bounds this would be; and this is good because these are maybe the last people we want building nuclear power plants.

Big corporations are inefficient and lack accountability. Governments are like big corporations in that manner, but also can't be held accountable by the market.

Corporate monstrosities can get away with being inefficient insofar as they can stay out of the red overall. Governments can get away with being inefficient insofar as we are forced to continue funding them via taxation. Note: giant, unaccountable, inefficient corporations usually became so large through monopolies created through government force (i.e. regulation).

Nuclear power plants are not large. They're definitely smaller than the literally hundreds of acres of equivalent solar panels. [1]

[1] Solar requires 3.4 acres/GWh/yr according to 2013 study. (https://www.nrel.gov/docs/fy13osti/56290.pdf). The smallest U.S. nuclear power plant was built in 1970 and generates 582 MW (https://www.eia.gov/tools/faqs/faq.php?id=104&t=3). That's 3.4 acres/GWh/yr * 1000 GWh/MWh * 582 MW / 24 h/day / 365 day/yr = 225 acres of solar panels.

Thorium, alternative reactors, reprocessing - all of this requires a lot of research and it's exceedingly expensive. Private entities won't touch it and it's difficult for governments to invest.

If the numbers added up China would be doing it already, but even for them - where they can still socialize the costs of failure (i.e. if it blows up, oh well, whereas in the West there's $100B in lawsuits) - it's expensive.
It follows UTC, so that doesn't apply. From what I understand, it does follow things like leap seconds, though.
Seconds don't vary, your approximation of a second varies.

If they made Windows 10 Pro more like the Pro edition of earlier versions, i.e., targeted at smaller businesses or power users who want a professional OS but not all the enterprise hassle, I would think they could do very well. But a professional OS doesn't do things like taking control of your computer to update or reboot whenever it feels like it or forcing you to upload any data you don't want to.

I have a suspicion that at some point Microsoft are going to back down on the big deal-breakers. They don't try to push their luck with those kinds of games in their enterprise products, because the big customers simply won't accept them. The frequent failures are just proving the critics right, and there have already been tentative moves to moderate the problems with mandatory updates. If changes in that sort of direction go far enough, they will appeal to smaller but serious customers who aren't running enterprise editions but have similar concerns.

If Microsoft really don't take the hint and back down when it comes to the crunch, I suspect Windows 7 will make the immortality of XP look like an amateurish trial run. I know my businesses all stocked up on Windows 7 machines a couple of years back while we still could, and since then we've been actively investigating multiple possible alternatives to Windows desktops for future use. Looking for alternatives seems to be the general trend across the other small tech businesses within my network as well, so if Microsoft think they're going to call everyone's bluff and get the whole world to migrate to 10 next year by shutting off updates for 7, I suspect they have seriously misjudged their market.

Thanks! This is very interesting.

I agree that to do it efficiently at scale, you need to change a lot. But they could easily have started with an Instacart-like approach, where every night when the stores are empty they have people pull and pack from the regular stock. That gets them into the game, and as buying habits change, they can start optimizing for the patterns that emerge. There are a lot of levers they can pull to keep that from disrupting store operation, including geographic rollout, limiting product selection, and marketing spend.

That's not optimal, of course. But neither is waiting until Amazon has a huge lead. So I still feel like they weren't thinking far enough ahead at a business level. Which as Clayton Christensen has shown, is pretty common for successful businesses.
This discussion isn't going to be very meaningful unless you wanna tell us what 'best' means to you.

> First, progressive switching is slower than needed to even decelerate warming

Since climate models are certainly not as accurate as we would like them to be, this is hard to say.

Second, progressive switching can be really, really fast. Look how fast people moved away from feature phones to smartphones. Complete conversion within a decade. Energy production carries more lag but still, progressive does not mean slow. When options are more attractive economically it will be a landslide.

Tech improvememt is certainly not linked to war. Look at all the tech progress we made in so many areas in the past 60 years without any major conflict happening. There is no rationale for progress to be dependent on conflict, at least it is not a model that explains anything anymore.
