After some digging, it appears the particular tech they are using is Locata[1], which uses a time of flight based positioning system.

To deal with the terrible multipath problems in a site full of metal boxes, a phased array approach is used to so the receiver antenna is directional and electronically steerable. Locata have a clever way of doing this called vRay [2]. This uses time-slicing rather than many simultaneous receivers to cut costs, and you can see this ball of smaller antennas on top in several shots.

In contrast, the ultrawideband (UWB) tech you have linked uses the frequency specific nature of multipath to average out the error, but as UWB is over a range of frequencies used for other purposes, it is very limited in legal TX power, and so I suspect it would have range issues in this application.

Not everyone agrees. There is some argument over why they did not throttle back and ended up overspeeding, which meant they could not manually trim, and why they re-engaged automatic stabiliser trim when the memory items explicitly state not to do so. The throttles were at maximum during the entire episode. My understanding is somewhat limited but I’ve read that the stick shaker activation might have made them leave the throttles alone, and that they may have re-enabled automatic trim because the manual trim wheels were impossible to move at such high velocity. Re-enabling auto trim is what ultimately allowed MCAS to push the nose down for the last time, but it’s not clear to me as a layman whether they could have saved the plane given their situation prior to re-enabling it anyway.

This is just a guess, but maybe to simplify the tracking requirements on the ground?

With a minimal satellite system, your tracking needs to follow satellites all the way across the sky, and probably also needs to be able to rapidly make large changes in where it is aimed.

With a very large number of satellites, a ground station might be able to get by with only having to be able to track within a small part of the sky.

If you have enough that there are many of these small areas that always have a satellite in them distributed all across the sky, then even places that have a lot of buildings or trees blocking much of the sky should still have some patch they can view that works.
Groovy is chock-full of absurd little microoptimizations that will forever fail to make even the tiniest dent in the general overhead relative to java. For several years there was even an "assume equality of hashes match" shortcut hidden in certain set operation code paths.
I saw their pricing and don't know if the hourly model makes sense for co-working. For comparison I've used Deskpass (and have been pretty happy with it so far). You book by the day - for $200/mo you get 20 visits (and unused visits rollover), which comes out cheaper than Croissant.

Mormon belief is that baptism is one of the few strict requirement for entry into Heaven, but that it can also be performed for the dead by volunteer proxies. Even the most obstinate sinners and nonbelievers will gain entry into the lowest-but-still-pleasant level of Heaven if they haven't committed the unpardonable sin[1]... so long as they've been baptized, in person or by proxy. Combine those premises and it becomes an obvious moral imperative to gather as much historical genological information as possible to perform proxy baptisms for as many deceased people as possible.

Of course, this presumption of religious axioms also has a history of upsetting people of other religions, and the extensive information-gathering involved often uses borderline unethical methods, such as the various geneology research service websites that are run in one way or another by the LDS Church and include terms of service that let them use the info you piece together however they like.

You honestly value WeWork as a workspace, so I have a question: given the loss rates of WeWork, are you willing to pay 50% to 100% more money in the future for the space? What is your feeling about the willingness of others in the space to pay the increased rates?
For a game server cluster, I would be running a game loop implemented as a series of pure function functor-like objects, located "very near" a spatial database. In that case, I would be migrating to provide the very lowest latency, as if the system were running on a "geostationary" server just a few hundred miles overhead. (Which has to pause for a quarter second, once every several minutes.)

I very much see it as Crossfit. The WoDs[1] cost $0 and the equipment cost is relatively trivial - you can get this stuff almost anywhere and do it on your own. However, membership at a Crossfit box[2] commands a huge premium due in large part to the social aspect.

At Crossfit or fitness events, you also hear athletes[3] introduce themselves as X from Y Box. I can't help but be reminded of when I hear religious people introducing themselves as X from Y Parish/Mosque/Synagogue. It can become a central part of your identity and one of the first labels you apply to your self.

A bit off topic but what does the word 'constellation' mean? A quick Google didn't yield much, and I'm not entirely sure what field it's from. My guess is "a set of connected satellites"? Or is it more specific than that?
Nice work man
One less mentioned point might be that wework, among other things, sells "hippness to corporates". At least here in Berlin there are multiple extrapreneur gigs (startups composed of corporate employees funded by the corporate) rented into wework. I assume this breath-of-startuppyness is sold for more than the already usual high rates.
Note that unions are banned in the PRC under the putative claim that they are "unnecessary" as the workers already control the government.

I leave it to the reader to evaluate the veracity of that argument.
Reading a lot of detailed reports, I concluded that nobody at Boeing ever properly tested the conditions that happened by both Lion Air and Ethiopian, until much after the second crash. Boeing didn't do enough steps to reconstruct what happened by Lion Air, otherwise they would have never published totally useless procedure which was then followed by the pilots of Ethiopian. The actual testing in the proper simulator would have shown that the emergency procedure, as written by Boeing after Lion Air crash, just can't work.

The pilots in Ethiopian and all the passengers paid with their lives for a whole world to learn that.

The world knows because one pilot tried to partially reconstruct the conditions on his own in an older simulator, as there were effectively almost no new simulators because the Boeing's selling point was that the new model of the plane is same as an old one model, just to avoid the recertification and pilot retraining. So the said pilot did the test for youtube, showed that what the pilots probably did matched the emergency procedure, and that exactly that following the procedure most probably results in the crash, but had to remove the video once his employer became aware of what he did.

Biomarker for chronic fatigue syndrome identified
The Free Software Foundation doesn't agree that the US government can release software under the GPL. From their FAQ about GNU free software licenses.

>Can the US Government release a program under the GNU GPL? (#GPLUSGov)
If the program is written by US federal government employees in the course of their employment, it is in the public domain, which means it is not copyrighted. Since the GNU GPL is based on copyright, such a program cannot be released under the GNU GPL. (It can still be free software, however; a public domain program is free.)

However, when a US federal government agency uses contractors to develop software, that is a different situation. The contract can require the contractor to release it under the GNU GPL. (GNU Ada was developed in this way.) Or the contract can assign the copyright to the government agency, which can then release the software under the GNU GPL.

Can the US Government release improvements to a GPL-covered program? (#GPLUSGovAdd)
Yes. If the improvements are written by US government employees in the course of their employment, then the improvements are in the public domain. However, the improved version, as a whole, is still covered by the GNU GPL. There is no problem in this situation.

If the US government uses contractors to do the job, then the improvements themselves can be GPL-covered.

The user space libselinux developed by the NSA is in the public domain. Which is consistent with the above. Are you sure that SELinux contribution was not released as public domain and then incorporated into the linux kernel? Something the GPL allows which the OFL license in question here does not.
I've ran into that as well which gets worse:

Would it be feasible for them to build standalone cell towers of their own that connect to these space networks?

You can use lvm or zfs snapshots, but that's not what I'm talking about – I'm talking about in-app browsable history of things like documents or presentations.

Last I checked it used Baloo to do the actual indexing, the list of high priority features/bugs on the project site https://community.kde.org/Baloo (Baloo crashes a lot in various places etc.) and a quick google make it look like it remains alpha software at best, I'm also pretty sure it doesn't have an equally reliable index update mechanism. The most important thing about spotlight for me is that it can search file names and content (filtered by type if necessary) fast and reliably and up-to-date. But you can also do types of searches that as far I'm aware of none of the linux utilities can do.

E.g. show me all the items I downloaded from a google.com domain:

mdfind "kMDItemWhereFroms == '*google.com*'"

If I want to see the filetypes that where downloaded sorted by frequency I can add

mdfind -0 "kMDItemWhereFroms == '*google.com*'" | xargs -0 -n1 mdls -name "kMDItemWhereFroms" | sort | uniq -c | sort -n

> For example I can run math calculations in it - which I haven't yet worked out how to do in
Spotlight.

You literally just type what you want calculated, e.g. `sin(pi/4)`.

> As a counterargument I could list a dozen things that are in Linux that aren't in OSX. Like up to date core utils and proper package management.

nix. By my lights the only proper package management for any OS. Works fine under both linux and macOS (and will also trivially supply you with up to date coreutils).

> But do you actually use desktop Linux on modern hardware?

I have been using (well-specced) linux desktops for most of my work for a long time.

> The problem there is the application. However Linux will just kill the last process that over allocates memory.

I don't think that's how it works. The whole point of having a proper OS (rather than say DOS) is that misbehaving app won't just bring down everything else. Also if you have a process that wildly allocates memory, by default linux will start off swapping like mad, making your computer effectively unusable (and yeah, in fact my linux desktop does have an SSD and many times as much RAM as my macbook, so if I'm not comparing like to like my linux station is the one with much more powerful hardware). And even if it runs out of swap it doesn't just kill the last process, it uses a more complex scoring algorithm which has a good chance of killing something you didn't want to be killed.
We run our infrastructure off of cloudflare, so we can easily spin up a staging environment that's an exact replica of production (only difference is # and size of instances). We also run a staging jenkins server that's defined in the cloudflare config.

We keep our jenkins jobs version controlled by checking in each job's config.xml into a git repo. In the past I've seen the config.xml files managed by puppet or other config management tools.

This helps us get around the "hard to backup" and "test in production" issues. We can test out jenkins changes in staging, commit those changes to our jenkins repo, and then push up the config.xml file to the production jenkins server when we're ready to deploy.
When I was in another commonwealth country, Australia, I found that newspapers would often dance around uncomfortable issues to the point where you wouldn't even know what they are talking about.

I will point out that the Switch already supports untrusted and unvetted code execution—it's called Javascript. The Nintendo Switch may appear to not have a web browser, but it pops up when you try to log into a captive portal. Without it, no one would be able to use public wifi hotspots.

I will also note that Nintendo hasn't exactly done a great job at preventing piracy or homebrew on the Switch—both are available provided you have a somewhat older model, and on the latest firmware even.

I've actually thought about this quite a lot. Not because I have an expertise in the matter--I don't. But because it's such a fascinating thought experiment.

My proposed solution goes something like this: It is hard to convey that there is nothing of value and only danger within. So what if you just made the site actually dangerous on the surface? Is it possible to build something like a lake of acid that would make the area uninhabitable, dangerous, and impossible to develop?

Or, to keep it more abstract: Maybe the problem is that we're looking for the right symbol. But instead of symbols we should make the fact of the area itself the deterrent.

Ok, make it 14 instead of 10 then. That's a small correction. Filling the gaps on the other hand does not require a factor of two, but only 2 \pi / sqrt(27) or about 1.21. Multiplying the 14 with that gives us 17 instead of the 20 I estimated. I don't want to squabble about 20% here, but ask about the factor 100 discrepancy between naive estimate and projected number.
