One sleep hack I recommend to everybody is to try to avoid waking up to an alarm. I now adjust my wake time mostly by adjusting my bedtime. This certainly makes my mornings better, but it also means I fret less about getting the right number of hours, in that I trust my body to generally self-regulate on the right amount of sleep.

Not everyone has the luxury nor the natural sleep cycle to be able to do this, though, not at times society expects us to be awake.

I've had luck getting good sleep waking about 8 or 9 with an alarm, but if I do not use the alarm, I oversleep. It doesn't matter what "healthy sleep habits" I use. Anything before 8 or 9 is impossible without an alarm, even with healthy sleep habits and reasonable bedtime - when I can get to sleep early enough to do such a thing.

I can train myself to wake around 10 or 11 most, but not all days, and the alarm is really more of a backup than anything. I can usually trust myself to wake by noon on my own, though.

You see, I am naturally a night owl. It isn't age: I've been like this since I was young and I'm nearly 40. As in, I chose sleep over santa presents. But additionally, my sleep needs change through the month, corresponding with a female hormone cycle. of course, that same cycle makes it harder to sleep earlier in the evening during times I need more sleep.
But really, who cares?
Not really, no. There's the FSF interpretation on one hand, but on the other there are companies like VMWare which happily put binary blobs into the Linux kernel and don't consider it a "derived work".

I like the X3 series (though I haven't tried the controversial rebirth). It has an interesting mixture of building empires, dog fighting and doing missions. They learning curve is a bit steep, but there are lots of enthusiasts modding it.

Edit: I just looked up when X3: Terran Conflict was released, which was 2008, so it's not exactly new!
I am embarrassed to say that I am confused about what the outputs are from the "Rapid" RL training system. Do you end up with an executable that then drives the game inputs/api? Does it produce a "bot script" that is used by the game to drive the logic? I understand that thousands of CPUs/GPUs are used for the training, but then what is actually playing the game at the end of the day?
That is an important point; you might be ten times more talented than Google engineers but you won't get your browser promoted on the on of the most popular internet pages or preinstalled with Android. Google is using its dominance in one area to disrupt competition in other areas. I think that this is something that should not be allowed.
> Me neither, in this context - though there's the US legal concept of "exigent circumstances" which allows police officers to enter property without a warrant if they believe a crime is in progress.

Indeed, I had encountered 'exigency' and so had some idea of the general idea—just never 'exigence'.
The 2018 MacBook Pro having thermal issues doesn't surprise me after seeing what my 2015 model does under load, but it's really disappointing since I've been anxiously waiting for Apple to release new laptops.

This 2015 MacBook Pro will avoid turning the fan on at any cost. I frequently watch the CPU package heat up to about 190F while the fan is still at 0RPM.

Further, the SMC chip and/or kernel are set to use fairly slow fan speeds compared to the amount of heat being produced, so even when it does come on, the system remains hotter than necessary.

But, here's the major problem: it's also become clear that there is a thermal window where the system is hot enough to cause it to throttle itself, perhaps somewhere between 140F and 180F, but not hot enough for the SMC to turn the fan on fast enough or at all, even though it could and should.

So in addition to being really hot and not using the fan to get the heat away from your lap, it gets slow at the same time, right when it's being used. The system becomes faster soon after the fan is turned up to the max.

And to top it off, there appear to be two different throttling mechanisms, the CPU speed can adjust up or down (you can see this with the Intel Power Gadget), and Apple has some kernel system that will use CPU cycles for idling instead of scheduling threads that are waiting, which reduces overall CPU usage, and therefore also heat production.

All combined, it looks like the system is constantly bouncing between ramping up the CPU frequency to handle load, then wasting some of the additional CPU time idling to avoid turning the fan on, then turning the fan on just long enough to get the heat down before turning the fan back off again, and repeat.

> Correct me if I’m wrong, but a group of doctors could form an organization that forces its patients into binding arbitration for disputes while still being contracted to the NHS.

Could they? I thought the doctor's contract is with the NHS on standard government terms, and the patients are dealing with the NHS terms, the doctors have no direct contract with the patients or ability to impose legal terms on the patients differing from the NHS terms.

Data point of one incoming. I work in ecommerce. 90% seems stupid low, based on our data.

A couple years ago we were seeing a dozen or so successful login requests per minute against a background of ~40 unsuccessful requests per second.

The principle of the rule of law says that all parties, even the government itself, are subject to the law. This would imply that any application of force on the government's part must only be done in the service of the law.

This is how government ought to be, and has been at least several times in the last 1000 years. The Magna Carta is famous for first codifying the rule of law principle.

The problem I see is that those iterations are constrained to not touch core parts of the hardware due to the lack of code and documentation being out there in public. Working with existing SOCs in different ways than their manufacturers ever thought possible is pretty common, many in the Linux-Sunxi community have pushed the envelope on how little power some SOCs can use, made possible in part by hardware features like a tiny, slow, power sipping RISC core that was on most Allwinner chips but was never leveraged before.

The karman line, the generally agreed upon edge of space, is at 100km. This capsule apparently reached 118km.

It definitely didn't reach orbit and it isn't designed to be in space for long, but I wouldn't say it won't ever go to space.
(Cheers for asking! I've been wondering about that too, ever since reading it.)
Yeah I don't disagree here, my point was that Blue Origin's particular goal and product bootstrapping from space tourism has already been tried and more or less failed. Whereas Musk's/SpaceX's goal is to get a Mars colony going, they started with something different than space tourism and it seems to be working out.

true, but it is not sustained Gs, it's in a reclined & fully supported position (i.e., its more mechanical stress on the body than draining blood from the brain, which requires special training & G-suits to counteract). Also, this would an exceptional event, not the standard launch profile.

I'd call it a reasonable spec, though it does seem that each passenger should be medically cleared and, ideally, physically tested beforehand.

> Android being open at all was already a fight inside Google, this decision will essentially make it impossible for anybody win that fight in the future. I can't see why anyone would risk making an open platform again.

It was a calculated risk that had a handsome payoff, if it worked, which is why it had to be open source, anything short of open source and Android would never have taken off like it did with several handset manufacturers via the OHA [0].

Remember, the context surrounding the need for Android to use an open source model at launch was that they were the underdog, iOS was still nascent but steadily gaining serious market share. The incumbents -- whom Google was hoping to disrupt using the OHA as a trojan horse was Nokia (they enjoyed 73% market share [1] with their Symbian "smartphone" OS) and Blackberry. Nokia would eventually start the process to make Symbian fully open source in 2008 [2], so they could compete better against the OHA [3], but the process didn't complete until 2010[4], which by then was already too late.

IOW, making Android open source was a core part of Google's strategic play to gain market share, there is no point in crying uncle.

I do not have sleep apnea. I am just lazy and like comfort and productivity. I don't see why I should change if I have no evidence it is harming me.
Some explanation why it's so, courtesy this obituary of William Baumol:
https://www.wsj.com/articles/baumol-diagnosed-the-disease-of... (paywall)

An excerpt from the article:

"Dr. Baumol’s insight in the 1960s was that costs inevitably rise fastest for things that are difficult to automate, including medical care, garbage collection and the live performance of a Mozart string quartet.

It came to him in the middle of the night.

“It was 4 in the morning,” he recalled in an oral history. “I suddenly woke up and said I know why those costs are going up! I got up, wrote down a few notes, and went to sleep again.” His theory became known as Baumol’s Cost Disease."

It goes deeper than that. Many (most?) Android apps depend on Play Services. If there were an option to remove it, it would basically be a "break most of my phone" option.

To make this viable, at a minimum, it should be possible to search for apps that don't depend on Play Services, so you could remove most of your apps and replace them with alternatives.

But I expect most users wouldn't do this, and so there is little incentive for most apps to stop depending on Play Services. The only real incentive to do it is to be able to publish the app on Amazon.

I think Rumsfeld gets credit for it because he was using it in the most degenerate, disingeuous form possible. Rather than guarding against legitimate concerns and pursuing actual handling of potential issues, he was just trying to rationalize continuing policies that were demonstrably counterproductive. It's one thing to say there might be factors we don't know. It's another to day that simply because there might be such things, we should dedicate significant resources and lives to blindly flailing away under the assumption that it will help. A presumption of unknown unknowns puts you in a position of not acting, normally. There is no way to know that you aren't exacerbating and making a problem worse if you know that little.
I did a brief search because I was curious who was remembering correctly here. There have been several studies correlating "long" sleeping with mortality, but the study I found that attempted to control for confounding variables[1] seems to suggest that most of the differences in mortality in the populations studied can be explained by "depression and low socioeconomic status". It seems like a lot more study has been devoted to undersleeping than oversleeping, and I can't find anything convincing as far as maximum healthy sleep time and effects of over-sleeping. One study I still want to look at but haven't gotten around to yet is the stuff the NSF produced in 2015 when making its recommendations about sleep duration.

SMS is terribly insecure. Using it as a security system is a bad idea.

SMS verification is more for discouraging bots from making accounts by making it expensive--you need to buy a cell phone. Every SMS verification system refuses to send to VoIP type accounts for this reason.
Thanks! I had either missed that paper or had taken away more of the message that these errors are more likely to be from events like misdirected writes, cache flush problems (hence the high correlation with systems resets and not-ready-conditions), and firmware bugs (on-drive and further up the stack), rather than bit-rot.

Still:

> On average, each disk developed 0.26 checksum mismatches.

> The maximum number of mismatches observed for any single drive is 33,000.

Considering the latter can represent 132K on a modern, 4K-sectored drive, that's a remarkable amount of data loss, enough to warrant a checksumming higher up (such as in the filesystem).. in theory [1].

However, the fact that this was NetApp using their custom hardware as the testbed makes me wonder if the data are skewed, and if the numbers would be nearly this bad from a more "commodity" setup, such as at Google. The paper alludes to this when referring to the extra hardware for the "nearline" disks, and I'm always suspicious of huge discrepancies in statistics between "enterprise" and other disks, even more so when there's a drastic difference in comparison methodology.

It would be interesting to see if there are any numbers for more modern drives, especially as the distinction between "enterprise" and "consumer" drives is disappearing, if only because demand for the latter is disappearing.

[1] In practice, an individual isn't aware of the 16.5K/132K loss risk, which is vanishingly small compared to other risks, anyway, and businesses don't tend to care and have survived OK anyway.
It’s very interesting to speculate about all this, and also crazy to think all these predictions were only made in the last century. I wonder how much different this list will look in another 100 years (if at all).
For example, if the market cap were 1/100 of its current value, then the transaction fees per year, denominated in dollars, would be $1800000, yielding the same "P/E" multiple, and justifying the valuation at 1/100 the current market cap.
This was probably the most pragmatic transaction i've seen all week.
I'm wondering, who uses Jenkins nowadays and why?

A few years ago, at one of my first gigs in an enterprise environment, I used Jenkins for the first time to test and build my stuff. When I needed a newer version of my compiler or specific linter, some fellow had to install that on the VM that was running Jenkins.

Later, working in a more modern environment, we started using Gitlab CI. It was a bliss. I specified the docker image with my favourite tooling and my stuff got built in there. When some tooling changed, I updated my image.

At my current gig, again an enterprise, it is Jenkins everywhere. They do the most complex things with it, orchestrating entire releases, integration tests, etc. I don't know what to think of this yet.

How does the HN crowd see this?
In Metal Gear Solid V a wopping amount of the budget went to voice actors, namely the voice actor for big boss costed a boatload and had a lot of his lines cut after they had been recorded so that money went to waste effectively
If the game is crowd sourced its as if the crowd is the producer/financier so its pretty reasonable that people would be upset at the possibility of their money going to waste
