RISC-V has a HINT instruction that's a NOP on the cores that don't support it, but can be a microarchitectual hint on the cores that do.

One of the encodings for the HINT will almost certainly be a speculative execution barrier.
But in the specific case of launch padding, another microsat company could just as easily buy that same extra capacity from SpaceX. Sure, that's assuming SpaceX doesn't cram every launch to the max. There's also the opportunity to cross-shop a bit with other launch systems.
Agreed here. Thinking the authors should be rolling up a better view of “health dollars spent per year”.
I only use Windows at work, where I also used to be the helpdesk guy. These days I spend most of my time programming, so I am somewhat out of the loop lately.

BSOD-wise, Windows has been very stable for a very long time[1]. I am not a fan of Windows, but Windows crashing is a very rare event, and when it happens, in my experience the cause is either a) faulty hardware, b) buggy device drivers or c) crappy AV software mucking around in kernel space (over the last three years, almost all the Windows bluescreens I saw were due to crappy AV software). My work laptop has BSOD'd on me maybe once or twice in three years - and I am one of those people that rarely shutdown or reboot their systems. At the end of the (work) day, I put my laptop to sleep, and only reboot it when an update requires it or when it misbehaves very badly. So I am pushing the system pretty hard.

I did not have much contact with Windows 10, yet, though. My work laptop runs Windows 7, and between Windows 2000 and 8.1, Windows 7 is the one I like best, so I am sticking with it for as long as I can. WSL sounds nice, though. And I heard Windows 10 finally got a native, builtin ssh client.

> Even if you have 16-32 gigs of RAM, the OS still writes pagefiles to disk.

This one has always struck me as odd about Windows. Linux or *BSD, given enough memory, will not swap at all until you push them. Windows seems to do it "proactively". I suppose it gets less annoying with an SSD, but my work laptop has a slow 5400rpm HDD.

[1] I once saw a Windows NT 4.0 Server with six years of uptime. Personally, I shudder at the thought of a server that has not gotten any updates in years, but if that is not a concern, Windows is absolutely capable of accumulating that kind of uptime.
I enjoy K-holes though it's been a while since I've gotten to one.

One thing people don't realize is that ketamine tolerance is very long and hard to get rid of. It's easy to find reports from recreational users of it lasting years.
If you have excess electric capacity, I think there are more convenient things to produce, such as aluminum. It lasts forever, it's easy to transport, producing it is very energy-intensive, and there's a constant demand. E.g., aluminum is a big industry in Iceland thanks to its cheap geothermal/hydro energy.
3 months maybe, 6 months definitely (Jan'17)
Unlikely, all rocket companies get government assistance, usually in the form of launch contracts. SpaceX has launched several USGC payloads already for example.
Ars says the latency is 25ms. https://arstechnica.com/information-technology/2018/02/space...

They say it's due to lower orbits. Iridium is fewer satellites so they have to be higher. More w/ lower orbits means lower latency. Do you know if this is too good to be true?
Right. The word “should” is doing a lot of work in that sentence.
I am surprised you would say that about David Foster Wallace. I went to school with him from kindergarten until 6th grade and 10th through 12th grade, in Urbana, Illinois. Math was never his strong point. However he wrote manic funny stories that would make you laugh so hard you would start to cry. That is why you have to limit yourself to 20 Pages a day at most.
It's hard to argue that from an economics perspective this isn't an insane leapfrog type of event, assuming they can gather the necessary in-house chops to deliver good telecom service. Talk about an economic moat -- to compete on margin you'd first have to become a rocket company. And not just a rocket company but one who has technology to re-use rockets, which likely is a ways away from becoming replicated, nevermind commoditized to the point where it evaporates from costs.

It's even steeper than that. SpaceX could arrange to send up some payloads piggybacked on their commercial payloads. Their competitors could effectively be paying to put part of their fleet up.
Thanks for that. Seems to work. Kind of pointless.
While piracy happens all over including hot-spots such as the Gulf of Guinea and the strait of Malacca, the only piracy that has received significant news coverage in Western media is that centered around Somalia.
I don't think it is. I don't give a flying fuck about coffee or food or wine or any of that shit, but I can genuinely taste differences in coffee. I'd be surprised if you couldn't.

There's a little roaster in St Lawrence Market where I go and I pickup random bags of whatever coffees for fun, and they are extremely different.

Wine I've never been able to discern. I don't think coffee is in the same league at all.
It mentions this in the article Li-ion go have a life cycle of roughly 1,000 recharges whereas these have 10,000.
For real-time dictionary compression, with infinite-size dictionary (LZ77, using a hash table for O(1) pattern search), you can try:

git clone https://github.com/faragon/libsrt

cd libsrt

make

./enc -ezh <hugefile >hugefile.z

./enc -dz <hugefile.z >hugefile.again

For 1MB dictionary (faster, because of higher cache hit ratio, and using a much smaller buffer):

./enc -ez <hugefile >hugefile.z

./enc -dz <hugefile.z >hugefile.again

For the source code, check compression (senc_lz_aux()) and decompression (sdec_lz()) functions, much easier to understand than the Zstandard code (because of having less features):

I doubt it. The problem is the ground stations. Even if the satellites have routing like Iridium they have to come back down to Earth in just a handful of locations, which are probably thousands of miles from your destination.

For a point of conparison Iridium also operates from relatively low orbits but has latency that is only barely usable for voice. Iridium only has one civilian ground station so your calls have to be relayed from there.
That graph seems to be from this Techcrunch article: https://techcrunch.com/2017/10/30/aws-continues-to-rule-the-.... It also has another graph showing the growth of Azure and Google being much higher than AWS. AWS has a head-start, but others are driving pricing down. Yay competition!

With 30-35% of the market (if that graph/article is to be believed), it's not even really fair to say AWS has a majority (majority being usually used for >50%).

If Waymo launches the service this year according to plan, how that will affect the upcoming Uber IPO in 2019 will be interesting to see.

It obviously depends on whether Uber has a similar service ready or imminent before their IPO. They have great AI and robotics people recruited from top places. However, such a feat takes time.

Additionally, he's registered eul.im as a private company.

The registration info is trivially available by searching the company #(11072989) on his website. He is a Netherlands resident who registered eul.im as a one person UK software company. At least 10,000 other companies use the same postal address as eul.im. The software in question, as everyone agrees, has no revenue model, and isn't even currently available for download. [text on website reads "Download v0.27 (out on Feb 17, for real, no more delays)"]. This precisely fits the pattern of a shell corporation.
The simple bissection can over fit quite easily.

Could this sort of network make it easier for other satellites to connect to a network? Does a space-to-space laser link that uses SpaceX's network to worm its way to some ground station use simpler/lighter/lower power hardware than a dedicated radio air-to-ground link?
I don't think they're going to launch anywhere close to even 1/10 their network this way; there are too few scheduled launches and too many satellites in their planned network, even if they were able to overcome the technical obstacles you mention. Depending on the margins they earn, the few (if any) they launch this way may be a meaningful cost savings.
In this case though the high water items are not what feed people well - almonds and coffee?
I'm assuming SpaceX is building the satelites too? Haven't heard anything about that.
Any other country would love to have a company like Amazon. But the US wants to tear it apart.
Is this in reference to a news event? Apple has people who coach law enforcement on accessing iPhones, and one of the things they do is get them to access the phone quickly before one of the security time delays set in and the phone can’t be unlocked without bypassing the hardware encryption, which is an expensive process. One of the big mistakes the FBI made in the San Bernardino case was to ignore Apple’s direction and accidentally lock themselves out.

I don’t know what the response time is for Apple to return customer records such as purchase dates, iCloud login times, etc. Again, I’m interested to know if this in reference to a particular incident.
My understanding is that the version distributed was a draft purposefully leaked, rather than distributed by Damore.

Why should this be representative here? Shouldn't the leaker be punished for the fallout of distributing the draft, if the final version was more nuanced?

The Good in Comparison:

It's incredibly faster.

It does a spectacular job at emulating how real painting feels.

The color picker is a lot better in Krita, in my opinion.

Krita can use (some) Photoshop brushes out of the box, just add them in.

It has an (arguably) better interface, and four color schemes out of the box.

The Bad in Comparison:

It doesn't have the non-painting effects of Photoshop, which can be a huge downside if you tend to use those on your projects.

Summary: Flight instructor saw a drone during low-altitude hovering exercises with a student, tried to land, and hit a bush. Much like lasers I suspect the psychological role of drones as a pilot distraction could be as great or greater than the actual risk to an airframe. Article has good links to various drone collisions (all resulting in limited damage to the larger vehicle) as well as FAA study showing drones could be more dangerous to airframes than birds because of harder materials.
I really don’t get it. Their coffee is not good, at all. Blue Bottle is at least good coffee, but the wait is not worth it.
I don't disagree, but these languages can still be used to create useful programs for hobbyists and industry without having to learn those concepts, so I'd say it certainly counts as "easier to learn", the utility of those other skills notwithstanding.
I found that grinding through the problems, over and over again, while using the textbook as a reference, resulted in the facts becoming committed to memory. I think it worked in two ways. First was the obvious repetition. Second, it created "slots" in my brain that were receptive to related material. There may have been an emotional factor as well: Feeling "on top" of the material made it easier to learn.
The US is not even close to the first to have an armed populace for the national defense. English longbowmen are another example of an armed populace. Many countries have compulsory military service for young men.
It's not even smart enough to realise most items I buy are items you only need one of. E.g. if I buy a screwdriver set, or desk, or frying pan, I'll keep getting recommendations for other similar products. I'm pretty sure a random product suggester could do better.
How is Amazon harming society? I don't see how they harm consumers since either way, consumers are the biggest winners of those low prices.

If you are referring to self-published authors distributing ebooks being forced to take 35% on < $3 sales and 70% on > $3 sales on their platform; or merchants leveraging their reach to sell to a larger audience being undercut by Amazon on price then yes, they are harming society in some way.

But even their "harm" is as debatable as the "harm" of Henry Ford's mass produced cars displacing horse-drawn carriages mostly because they were more efficient at transporting people over the same distances as horses.

> communicate with it in both directions in real-time without significant overhead

Doesn't all the communication have to be done by passing JSON-encoded messages between threads? So compared to calling a function on the same thread, there is very significant overhead, especially if you want to pass large data structures (which would have to be serialized) or if the calling thread needs to block waiting for the answer.

But as long as you stick to send small and asynchronous messages, it doesn't have a significant impact on the user experience, I suppose.

Or did they do something to improve this lately?
This looks pretty fantastic, and the coverage map (https://coverage.sprint.com/IMPACT.jsp?#!/) looks like it handles most of the places I've been skulking about.

I like the sound of this, like an object graph of data from OSM.

> I am not sure how well this type of system could work in open street map. Is it too rigid? Or would there be too much proliferation of types? Classification is always hard and I am not sure people have solved that problem in any large context.

Ontologies are well-researched. Unfortunately they're not my area of expertise as I turned away from doing a PhD in them and went into business.

I have been playing with a controlled vocabulary since Christmas for a personal project and the complexity of definition has made me think this is why Google et al have gone for a more flexible, machine-learned typing, and why the types for schema.org are so broad.

Having been negative, I think this is exactly what OSM needs to organise the world's objects.
What exactly are you picturing here? Because of light-speed considerations you'd have semi-isolated networks at each major body, and bodies connected with special high-power high-latency links.

Gold compared to what Microsoft and many commercial ISVs dump on their customers as "documentation".

The Arch Wiki is superb, indeed. Let's call it platinum. ;-)

My issue is that if volunteer driven projects like FreeBSD, Arch Linux or OpenBSD can provide very high quality documentation, I expect commercial ISVs to provide documentation that is at the very least that good. Instead, documentation is often either missing entirely or very bad. Or they have the audacity to charge you extra for a manual.

> If I laid out our source code for you, there is no way you would have any way to understand it without all the internal documentation from which the software was architected and developed from. Non computer people always have this misconception that if they see the code, they see everything it's doing

This isn't a forum for "non computer people" - I've been a professional embedded developer, hardware and software.

This stance is wrong and terrifying. The code, safety critical code especially, should be clear and should itself document the quirks of whatever it interacts with. Embedded has a culture of punting on abstractions due to the pervasiveness of cross cutting and global concerns (peripheral allocation, interrupt usage, tight latencies, etc), coupled with traditionally smaller code sizes. But we're no longer talking about devices with little memory or cycle by cycle timing, but 32-bit devices with dynamic allocation performing high level logical processing. The embedded culture of fiddling with stateful hacks, verification primarily through system-level testing, and then zipping up the source tree for revision control needs to be burnt at the stake. Leave the bit banging to single-purpose 8 bit micros at the edge that cannot hide actual complexity - the core is a full computer, and needs a proper type system.

I'm not saying this change is going to happen over night, but we should be aiming for the correct approach. Every time a company says that they cannot release code because it is too complex, wouldn't be understandable, have third party dependencies, etc - what they're really saying is that their code base is a sloppy hack, they have no idea how it works, and they really do not want to own up to this state of affairs.

> For me or any company to support someone's quest to understand the code would be a very costly endeavor that you're simply not entitled too or nor would it be a reasonable request.

It might not be desirable according to a company's business interests, but what is actually unreasonable is to force purchasers and users of heavy equipment to blindly trust the software controlling those devices.
So, what does it taste like?
Philz was the first place where I could actually taste the difference in flavors between the different beans. I think it’s because they don’t burn their beans like Starbucks does. They also use heavy cooking cream rather than half and half. I am no coffee snob, but Starbucks coffee really is the lowest common denominator at this point, probably due to the scale they have to operate at.

Easier, sure. But Tupolev built and flew 100 flights with the Tu-155, a cryogenic H2 fueled narrow-body airliner, in the 1980s. So it's very far from impossible, it's just a matter of time IMO. Currently aviation is pushing biofuels to kick the can down the road, but they can't do that forever.
So it's a matter of will power and determination?
Hey I am in SRE. At one point last year there were 7 ex professors sitting within 15 feet of my desk including me (and I did a PhD in theoretical computer science at the same school as this math professor whose article we are reading). I don't think it is an underrated career.
Maybe I’m alone in this, but I feel like if you’re going to break up a company with antitrust regulation you should at least be able to point to a way they’re abusing their power or are making a worse experience for customers. The article goes as far as to admit that Amazon is currently not doing anything wrong.

Should we really seek to regulate away hard-earned (and valuable!) advantages because they make it possible to abuse the position? Surely we should wait until they’re actually abusing it?

As an aside, I can’t think of any advantage Amazon has that wouldn’t open up opportunities for a competitor should they start to abuse them. That’s the goal of capitalism, in a sense; you have to be great or people just go elsewhere. Seems odd to fight against that.
Luckily, sometimes views of fellow developers do in fact move the needle. Though I'm not holding my breath sadly.
Could do that without centralization.
Is this for an open source project, or anything you'll be publishing? I'd be interested to follow on with the results!

i wouldn't say that you're wrong per se, but maybe a bit too generous to the narrowly defined class of "software developer". plenty of other fields employ the same class of cognitively elite individuals.

off the top of my head:

* lawyers and accountants and some types of financial professionals
* aerospace engineers, rocket scientists, defense engineers
* physicists, chemical engineers, mechanical engineers etc.

many of these people also write software as part of their job, at a more-than-competent level, while i don't think your average software engineer could do their job in any capacity whatsoever after i.e. 10 years of experience of just writing code.
