Raising the abstraction level of the ISA and making more logic part of proprietary CPU microcode is exactly the wrong direction to go in for security. I'm not sure how the authors can possibly claim this will be beneficial for security. Thankfully, recent events (Meltdown and Spectre) have made the flaws in their philosophy abundantly clear.

>When considering the period of rapid evolution that microarchitecture is about to face with the end of lithography scaling, abstractions that are free from underlying microarchitectural influence are critical to minimizing future disruption.

Ironically completely accurate! If chipmakers can successfully sell us on super-high-level ISAs (moving the scheduler and hypervisor inside their proprietary chips, as this article seems to suggest), they will be able to lock us in and easily prevent any "disruption" of their business model.

The greatest advantage for innovation in ISAs in the past 20 years has been the development of Linux and GCC, which allow any new chip to get a huge amount of working software with relatively little porting effort. Moving more logic out of this open source software portability layer and into the proprietary chip will just make it harder to build new chips from scratch.
Is there a category for robot solvers that have to fulfil the same requirements as a human solver?

In other words, I'd like like to know how fast you can build a robot that has to start with the cube lying on a table in front of it, and the manipulators (hands, in the human case of course) being away from the cube, with the timer stopping when the cube is back on the table and the manipulators are back in their original position?

No, I think this is reflecting the fact that the optimal solution for some initial states is shorter than for others, though I could be mistaken.
> If anything, the new iMac pro has a Secure Enclave, which means we can soon expect in some number of years that most computers will as well.

I don't know about Macs but PCs have a Smart-Card like Chip called TPM build in for about 20 years by now.

One of the main functions a TPM offers is the secure storage of encryption keys.

I wonder such a feature comes only now to Macs with about two decades of a delay?
I saw a made-for-TV movie about the Steven Stayner kidnapping [1]. Stayner was kidnapped when he was 7 while walking home from school in Merced, California.

No one knew if he had been kidnapped, murdered, had an accident, or ran away.

There's a creek named Bear Creek that runs through Merced. At one point in the movie someone in law enforcement suggests that they dredge "the Bear Creek" to search for Stayner's body.

That probably sounded fine to most people watching, but it seemed very wrong to me. I lived in Merced or the surrounding countryside from 7 until I went to college, with several years living a block from Bear Creek, and I never heard anyone call it "the Bear Creek". It was always just "Bear Creek" or "The creek".

I once made a list (since lost) of assorted creeks, rivers, lakes, and other prominent geological features around the US and what the locals called them. Some almost always used "the" and some almost always did not. I could not discern any pattern to which did and which did not.

I wonder if a given locality is consistent on this? E.g., if they omit "the" from their local river, will they also omit it from their local lake?

I wonder if intelligence agencies, when sending people trying to pass as natives to someplace to spy, train them on this level of local lingo minutia?

OK. Now I get where you're coming from. I didn't realize that FileCoin was started by the creators of IPFS. That is too bad. You really don't need crypto as a vehicle for paying someone to mirror content.

With regards to Bittorrent... I guess where you and I differ is that I think Bittorrent is just as broke as IPFS when it comes down to it. Or maybe same type of broke, but less so than IPFS. While the seeding incentives certainly help bittorrent, I don't think it fundementally makes it better than IFPS. I know what when I've torrented things, I've always seeded less than I leeched. Long-lived torrents are either a) pretty popular or b) have some people intentionally keeping it alive... which is what I would expect in IPFS too.

I will have to go read those white-papers. If I'm reading your comment right, it sounds like you consider the broken-ness of IFPS to be so much worse than that of Bittorrent that you think it deserves its own category.

Or perhaps that the expectations of IFPS compared to its own broken-ness puts it in its own category. I think of Bittorrent and IPFS as distributed distribution, not storage. And while Bittorrent people see Bittorrent as distributed distribution (caching), IPFS markets itself as distributed storage. Which, that makes sense given the use cases IPFS seems to want to fill - it wants to replace static http stuff, whereas bittorrent seems to serve small more canonical files, stuff that's already always identical independent of the source. Like ISOs or other things that people were generally sending each other directly anyways.

I think it too until you last comment for all of the above thoughts to congeal. And I'm sorry it came off as adversarial. Thanks for taking the time to respond.
Wow. Amazing video to sum up a breathtaking event.

I really liked this bit from Elon's tweet:

Firefox recently switched to a design that tends towards a higher base memory usage than Chrome, but a lower usage for each new tab. With the same 30 tabs open and no extensions, the current Firefox uses ~30% less memory than Chrome. But opened only to one tab, Chrome uses ~60% less memory than Firefox. It's an interesting tradeoff.
> If your company relies on low skilled manual labourers working 12h a day for minimum wage or you go bankrupt... You should go bankrupt. It stops you from modernising and increasing productivity long term

Yes they would go bankrupt or move production or automate...like I said originally. Perhaps this results in less jobs in the economy and the low skilled get paid less, the economy shrinks and every one gets poorer?

There is an interaction between immigration and wage growth but it is not a simple or linear one.

The whole point of signing everything from the bootloader on down is to make sure that even ring 0 control over the computer can't persist through a reboot. Allowing signatures to work the way it was suggested would break any hope of something like Secure Boot ever working. As it is you're already trusting timestamping certificates to effectively live forever.

It was one question around detecting contractor fraud.

From what I remember, your STDIN would be a stream of logs containing start and end times for a job. eg

Alice 13:05 START
Bill 13:06 START
Alice 13:08 FINISH
Bill 13:09 START

In the above, Alice is fine because she started and finished her job but Bill would be flagged for possibly fraud for starting a new job before finishing his old one.

I think there might've been some additional criteria too. Anyway, you had to scan the incoming data and return any possible anomalies.

I guess that's a possible insight to what they're working on?

That article didn’t have any sources and blamed pathological perfectionism on psychic wounds. Ok, it’s not a bad theory, but remember when we figured out that some peptic ulcers came from H. pylori, not just being uptight?

Behold some really fascinating research on perfectionism, OCD, and Tourette’s:

1. Perfectionism predicts OCD symptoms.
https://www.sciencedirect.com/science/article/pii/0005796795...

2. Tourette’s, OCD, PANDAS share immune disregulation link.

3. Yale: Mice with grooming tics cured by giving them histamine https://news.yale.edu/2017/06/05/tourette-tics-vanish-mice-t...

4. Oxford: Connection between basal ganglia, histamine, and OCD & friends
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4917894/

I know the article was about personality/perfectionism not tics/OCD, but I find this idea that issues around “obsessiveness” could have an immune/histamine/basal ganglia cause so fascinating, since I myself have OCD and would very much enjoy not having it, even if that took the edge off my high-achieving/driven personality. They haven’t teased it all out and there is no medical treatment based on all this yet. But maybe someday?
Elon Musk crashes SXSW panel to talk about space travel
Yes, that could be molecular mimicry. I hadn't heard of the thyroglobulin gluten similarity. But Hashimoto's thyroiditis is associated with celiac disease, which is clearly gluten related.

As the immune system matures in late fetal development, there's a stage when all cells that can target self antigens get killed. However, some tissues are isolated from the immune system, and so there are antigens there that don't get on the "self list". The thyroid is one of them.

Everything is OK until the thyroid gets damaged, infected or whatever. Then the immune system can see it, and may develop cell and antibody mediated responses.

Like all proteins in food, gluten is normally digested, and never makes it out of the gut intact. Only the component amino acids are transported to the bloodstream. However, in celiac disease, where the gut lining is damaged, I can imagine that some gluten gets across intact. Also many other proteins and complex carbohydrates.

Then the immune system could respond to all that stuff. And some of it could share epitope with thyroid components. So if there is an association between gluten and Hashimoto's thyroiditis, it's hard to say whether gluten shares epitopes with thyroid stuff, or whether it's just damaging the gut.
At least Firefox is open source and probably doesn't broadcast your passwords back to the server.

1Password is closed source and stores your passwords on a server which, should it ever be hacked, could easily cause all sorts of issues. If they received a secret order to compromise your accounts Lavabit-style, they wouldn't even have to be hacked--they might willingly backdoor their own product.

I use KeePass or KeePassX (depending on platform) which never require me to store my password database on someone else's computer.

Even the kernel can't modify its own code and persist through a reboot. The kernel only loads signed code that isn't malicious, the bootloader only loads signed kernels that aren't malicious and don't allow you to run malicious code as ring 0, and the BIOS only loads signed bootloaders, etc. There's a root of trust from the hardware on down that makes sure that you cannot run unsigned code as ring 0 and if there's a compromise it can't persist through a reboot. Allowing the kernel to mark certain modules as "signed" like you're suggesting would allow a rootkit to install itself via some exploit. This would render moot the whole point of Secure Boot in the first place.
Gmail filters. Take a month. Whenever an email comes in that is not actionable, unsubscribe, or create a rule that either trashes it or sends it to a low priority folder. PayPal notifications of monthly statements, your credit card bill has been paid, mailing lists, make a rule for all of em. Now your inbox contains almost exclusively email from a person to you. This makes it far easier to operate at inbox zero.

Unless you lack the memory necessary to do something else, you shouldn't care.

This is exactly the attitude that leads to such problems. Applications that assume they can use all of the available memory on the machine are hostile to multitasking environments.
It depends. If it were just me by myself maybe. I was working from home and my wife and my two sons were home. Both of my sons were playing online on their PlayStations (my older son bought his own) and my wife was streaming Netflix. 50/10 was unusable for work over a VPN.

We have since moved and now have gigabit internet up and down and usually get 930+ u/d wired and 250 u/d wireless. Our whole house is wired for gig-e. It's overkill.

The closest I ever get to using it is connecting to my job. In the middle of the night, I can get 80Mbps.

Even if we did stream 4K content at 15K - 50K we would be fine with 200Mbos.

I think I have a valid argument for this theory besides people mistaking this with Shaquille O'Neal's 'Kazaam'. In an episode of Nickelodeon's 'All That', Sinbad once played the father of Ishboo (played by Kenan Thompson) 'Sinboo'. And I recall his clothing being very similar to that of a Genie. Can enough people be mistakenly conflating their childhood memories of Sinboo and Kazaam and creating 'Shazaam'..?
> (In the United States, a country with far higher litigation costs, government agencies overseeing play safety are not known to have made any such changes.)

That's the first time in a while that the New York Times has really made me laugh. The article pictures British schools as a model of educational enlightenment, and takes a swipe against an obsessively litigious culture that's seeping into the lives of infants. It shows how implementing commonsensical educational policies is a bipartisan issue, and that the wider litigious culture is the roadblock to helping kids develop well-tuned resilient and risk-taking behaviours.

Palantir gets deployed on classified networks. There’s no central Palantir instance. Those instances get integrated with classified data sources by people with security clearance

And yes, getting access to that data is hard (and should be!) One of the reasons Palantir gets contracts is because of their large cleared workforce.

> Yes they would go bankrupt or move production or automate...like I said originally.

Yes you did. Did you miss the part where I replied to that?

> Perhaps this results in less jobs in the economy and the low skilled get paid less, the economy shrinks and every one gets poorer?

I'm sorry but what are you talking about?

Shitty companies going bankrupt does not mean less jobs or lower wages, in fact the opposite. It's natural and a good thing in a free market. So I don't know what you are on about here.

> There is an interaction between immigration and wage growth but it is not a simple or linear one.

Oh for sure. Immigration can definitely increase wages and the economy and create jobs. But you forgot the low skilled part.

Look, this thread has gone long enough and you're not addressing most of the things I write, so I don't see the point of this.

All I wanted was to clarify that the UK did not in fact have any power to limit freedom of movement of workers from the EU, that's it. I never wanted to argue about anything else.
They sort of are though. It's just that a person's importance isn't individually obvious, and only becomes obvious in aggregate.
Palantir basically does "splunk" except with a UI normal people can use. Honestly, I think ingesting your data into splunk and creating in house splunk apps is a superior solution.

What palantir has is "connections" with the intelligence and law enforcement communities. They basically brought "big data" to cops and spooks(and now the military too I guess). They don't do much that isn't done already by other private sector/silicon valley companies
Yeah from Theil's books he leads to it. In fraud, people and computers combined are pretty powerful. So the company just creates tools to help a human find issues. An analyst would come into work and see a massive dashboard, then notice contractors pay has doubled since last week, then drill into "contractor irregularities", then see one user perform 200 jobs in the last hour, then click on the user's geo information and realize it comes from an IP address in Florida, then they click on "open ports", the machine has port 80 open (hacked). They resolve the problem by creating a new rule, "IF user job count > X, per hour || port 80 open, pause payment && report". etc etc. They just keep adjusting these rules to keep fraud rates down. It isn't ever 0, but they keep modifying the rules to minimize OVER and UNDER reports. It is comically basic.
I tried to play with my 4 y.o. son to NES classic games. He loved Donkey Kong County, and some other arcades, but I found games affects his behavior in a bad way. He was always asking to play more, refusing to go and play outside, working at home with books, paper, and color pens and water paints. So we're not playing for 6 months or more. He loved plasticine, and makes some really fancy and realistic animals. He likes water painting on the paper, and likes when we read him books. We believe video games is not something we should hook up our kids for. Avoiding games, and limiting the amount of youtube videos to 30-60 mins helped a lot.
It becomes haranguey if it happens often enough.

I'm not sure your point is borne out by the thread. Most comments are civil and substantive. It isn't the highest quality discussion but graded on a curve it's good.

My inclination was to penalize the article because of the triggery title. But I took a look and had to change my mind. The article is substantive and gratifies intellectual curiosity; that's the site mandate (https://news.ycombinator.com/newsguidelines.html), so I'd say it's clearly germane.

The topic itself is troll city, of course, which is why I posted the sticky comment at the top. We have to judge this by the article, not overall topic. Even if nearly everything on a topic is crap or flamebait, occasionally something isn't, and it's important to how HN works to treat those exceptions differently—even though having blanket rules would be easier, and a lot of people mistakenly think we do have them.

Additionally, if you supplement or take K2 with vitamin D, the risks are substantially mitigated (Vitamin D adds calcium ions to things, K2 takes them out).

It definitely is not a naive question. Printing money is precisely what the government should do. Income tax should be eliminated, it is a relic of the past. The government should fund itself not by selling bonds, which essentially is printing money that pays interest, but by simply printing money which is more direct.
FWIW, I'm a Google dev and my only computer is the same 2015 15" MacBook Pro that many of the people reading this have had. Anecdotally, most of the developers I see are in the same boat (using a rMBP as their primary machine).

Many of the folks who work in our monorepo have an additional Linux workstation - not sure what the specs are on it, or what the average split is between laptop and workstation surfing. I also haven't paid that much attention to see if the folks I know on the Chrome team have substantially different usage.
