Actually the active area of the CMOS sensor is really quite small. Like ~0.1cm^2. It is the main reason we need so darn many phones (and, as you correctly point out, an appropriate density of phones) in order to have sensitivity.

The reason it's still interesting is that at the very very highest UHECR energies, like above 10^21 eV, the density of ionizing particles is so tremendous that it's almost impossible for a (tiny) camera not to see it, if it's close to the core. This is great because unlike the Pierre Auger observatory (which is already about 100% effective at detecting showers above 10^18 eV), we become better and better at detecting events the higher the energy. So while P-A has pretty much constrained the UHE spectrum up to about 10^20 eV, the limitations on its size (as in, how much area it covers on the ground) means it can't do any better, since the higher-energy events become so rare that the probability of them happening over their patch in the desert is quite small.

The hope with CRAYFIS is that, given global coverage, we can be the most sensitive measurement of these ultra-rare events at energies above what P-A has been able to observe.
In 1989 about 8% of the population of the Soviet Union had been through tertiary education. The modern UK sends nearly half its young adults to university, including an awful lot of people whose parents are manual labourers (we don't, admittedly, have any peasants)
IMO, test suites without parameterized test cases are not good.

As such, you need pytest, nose or unittest + ddt|nose-parameterized.
ok, call it 'social rearrangement'. Lets make Mexico more democratic, give more power to people, protect elections, and give basic income to every Mexican. Gates's money is more than enough to provide basic income to 10 generations of mexican people. Will never happen though.
Her background is like a whose-who of scheming companies and groups. She was apparently pretty effective, too. Not that great an example, though, given people only care about nuclear so much.

Our best example in recent times is still 2008. In this case, the elites crash the whole system, get paid off for it, and get criminal immunity. This kind of event and resulting deal should be non-existent in a democracy. Whereas, in Iceland, they overthrew the dirty politicians, jailed them, jailed the bankers involved, seized banks, and reoriented their banks and news to prevent such things in future. Healthy democracy in action.

The media's role in keeping elite's schemes going is pivotal. I think the strategy has to be on them. Anyone doing a revolution should hit the media rather than just the government. Make sure each side gets a say with reporters digging into root problems and potential solutions. People can then push for what they believe will work through regular, government structures. They can't act without being informed. So, corporate media is root problem here.

Note: I've observed the same thing in Russia. Their media, at least RT, is even worse as it's basically a government spokespiece. Ours still compete with each other with at least several calling out government in big ways without anyone getting shot. The times they self-censor and are pervasively corrupt are protecting capitalist class that funds them. So, huge problem, but enough media protection here to maybe accomplish something. I'm more worried for Russians given Putin's recent laws on bloggers, etc plus risk journalists face in general.
This is crazy timing. I'm playing Chrono Trigger right now and the thing that struck me as fantastic UX this playthrough is that Crono shakes his head when you're trying to go somewhere you can't. I found it particularly useful when walking on the beams in the Arris Dome. It maps pretty well to the design pattern of shaking prompts when entering invalid input such as an incorrect password.
> For one, asserts are removed when you run Python with "-O", so, uh, good luck running your test suite in that configuration.

That's almost entirely all python -O actually does. The only other thing it does is set __debug__ to 0. There's essentially no real value in running code with the -O flag.

I don't agree, this is not exactly the same as a tl;DR for maths.

IMHO, this is more a way to make people (game developers) feel mathematics intuitively.

It is somehow the same as the setosa.io approach which is all about visual explanations.

This is pretty cool.

The US flag is the flag of Mankind? Interesting.
The problems with owning are:

1) You have to buy for resale, not to fit your budget best. People tend to want to max out their mortgages these days. And if you are trying to sell into a downturn, it can be a problem.

2) Fees at time of sale. 6% twice ( once at purchase, once at sale ) eats 12% for the life of the mortgage.
And that’s exactly the opposite of how you build efficient and secure systems.

This is basically sandboxing time itself.

The bad software will never be fixed. Never. But you can put it in a jail, and let the user configure that good software won’t have that jail.
You'd have to be more specific. I haven't studied India's history that much. I just know the result of globalization have been a fraction of a few countries' populations get rich essentially doing nothing while most population produces that wealth. And some countries almost totally do that for benefit of others. India appears to be one of those countries. So, it's in a modern form of economic slavery to rich, imperialist countries that now use capitalist tactics instead of bullets.

I'd still be interested in whatever historical points or patent differences you're talking about. I'm also assuming you're Indian as well?
> Cast your mind back to when SIGHUP first started getting sent to processes on logout.

That would be before 1979. nohup was in 7th Edition. I haven't checked 6th.

Ironically, by pointing to the fact that one has to go back through 37 years of documentation, education, user experience, and scripts you are making other people's point for them. Especially by drawing attention to one of the major flaws in the "nohup was new once" argument, which is that in 1979 (or before) there wasn't a prior 37 years built up to contradict. (-:
I'm quite sure I'm not the only one to use an ad-blocker with TorBrowser, so this would not be a unique fingerprint.
I go further and ask myself if the problem needs to be solved at all. A lot of premature optimization falls into this category.

You can just uninstall it and use something else to configure networking. It's one of the first things I purge on any distro.

With systemd it's not so simple.
A database backend which makes searching through packages, and occasionally being naughty and altering manifests, easi. It's fast as hell, like faster than apt, it lets you lock packages to a specific version, etc, so you can do things like have 2 or 3 packages built with special flags and still use the package management tools. It's fantastically clean too and well documented, as BSD software tends to be.

This is the level of discourse I've come to expect from any discussion related to systemd
I think you replied to the wrong comment?
Computer software and hardware are an interesting case where often, the more expensive something is, the worse it is; the best stuff is often quite cheap. This comes from the high upfront costs meeting very low marginal costs. A cutting-edge chip fab will cost $10b+ all told right now, but can produce millions of chips a year at trivial costs.

I knew as soon as he mentioned military VR results that his case was going to be based on ancient and inferior hardware and outdated results, and include no actual results or even first-hand experience with a Vive. (At the most generous reading of the article, he worked with a DK1 a while ago.)
It may also whet the appetite for more deliberate study of the mathematics involved. I have always been one to struggle a bit with math concepts if they are too abstract. Tie them into somthing I have real-world interest in, and it's much easier to engage and stay motivated to learn.
> Germany is culturally a nordic country

On what grounds? There were a lot of states that went into the modern Germany, surely you're not saying they were all nordic.
I'm also very skeptical that the military units are as good as the consumer versions we have now.

We have predictive tracking and timewarp to reduce the felt latency to virtually zero, does the military unit have that? Full positional audio?

I'm sure the military have fine engineers, but do they have John Carmacks, Mike Abrashes, JMP van Waverens, Cass Everitts, etc.?
There's also this skeleton for Google App Engine:

This got me going with Flask. It's not quite everything you asked for but it lays a foundation upon which to build and explore the different features you've listed. And App Engine's free tier provides a nice platform for prototyping and simplifies deployment.
Thanks, I'm new to ycombinator and I find the interface pretty confusing.

Quite the opposite really, the UK (and more specifically england) is leading the neoliberal charge in Europe. If anything, brexit would increase its velocity not change its direction.
We read about them! Very cool project, especially from high-school students. A lot of people got onto this idea about the same time. See also CellRAD, which is an app that is supposed to act as a dosimiter to detect when you are near radioactive sources. It's been known for quite a while that silicon pixels can detect ionizing radiation (in fact, that's why we use pixel detectors in the inner tracker layers of state-of-the-art particle detectors such as ATLAS and CMS). The problem with the pixels in the CMOS camera of your smartphone is that they are very small (in both pitch and depth) and were optimized to respond to optical photons, rather than charged particles.

We have played around a bit with implementing these radiation-sensing features, but the main goal for the CRAYFIS project (and which sets it apart from other similar projects) is to create a distributed network of phones that all work together to act as a giant telescope for UHECR events.
I mean, find an example of the problem, instead of creating a problem, and assuming it's widespread.
DTrace, ZFS, and containers should be major differences. Serious changes in how admins' jobs work have resulted from just those three. A whole cloud platform has been built when that was added to other benefit of open-sourcing one. So, Sun's OS got transformed into a pseudo-mainframe with better debugging and possibly better filesystem. I don't recall enough details of mainframe FS's to be sure on latter.

Far as Linux, Ubuntu with its software-center, Flash, VLC, and so on are much different than my early experience with Caldera OpenLinux on a Pentium 2. Which would've looked like shit with almost no apps or features had it not bricked that machine during install. ;)

So, they're not very innovative but have had huge improvements that totally change the user-experience. I mean, certain things are similar or the same especially on terminal end. Yet, we can't pretend like UNIX has sat still. It's just still not fixing its worst issues or learning from prior work as effectively as it could.

The BSD systems have had 20+ years of divergence. There are areas where they'll borrow from each other when one of the others has a tool that works better than the status quo, but the kernels are vastly different animals. When a BSD does make a world-breaking change, like pledge(), it owns it, and will patch software itself to handle it, not pester upstream to stop what they were working on to implement their special snowflake code, which is what the systemd developers want to do.
The U.S. Constitution consists of lots of statements that grant the federal government powers. These statements have logical implications. Logically valid implications of the enumerated powers ought to be constitutional, right? It would be absurd to say the Department of the Air Force is unconstitutional even though there is no explicit mention of the federal government being granted the power to have said department. Should there be 50 different states with their own departments of the Air Force?
> There's NOTHING new or innovative about this! Processes are already reaped at logout, unless they're nohup'd. Changing the state of affairs to "processes are reaped at logout, unless they use dbus to ask systemd to not reap them" is just a bunch of mechanism churn to get the same result

The difference is that pre-systemd, there is no safe way to guarantee that all processes are reaped on logout if some of the processes are written maliciously to try and avoid being reaped. The new cgroup-based system makes it impossible to evade being reaped by playing games with fork. This mechanism is valuable, but it is possibly not the best default for most systems.
Python 3.0 was basically a line in the sand to throw in all these "unnecessary" breaking changes. At the end of the day, no changes are actually necessary.

But to keep Python improving without weighing itself down, some changes couldn't just be slipped into the 2.x series. Because they're fundamental enough changes to even effect toy programs.

So, yes, I'd say that the default string type did need to change from bytes to unicode. And not only do I not miss str.lowercase, that kind of vestigial feature is exactly the type of thing that should be purged with the unicode transition.

I believe you're massively overstating the problem.

Not all of the libraries you use are embedded. Only the ones you need that aren't part of the platform you're targeting are.

For example, if you're building an app on the GNOME 3.28 platform, it would presumably include (for example) an SSL library like OpenSSL. Now, whenever the platform is updated (3.28.x), all of the apps that target that platform (presumably all of them) will get the updated OpenSSL for free.

And if an application really needs a specific version of OpenSSL, then at least you know it's sandboxed, which is much more than you'd get on almost any desktop Linux distro today.

From the website:

"Dependencies that aren't in a runtime can be bundled as part of the app. This makes it possible to use dependencies that aren't in a distribution, and to use a different version of a dependency than the one that's in a distribution."

I tried about a year ago and I couldn't get past the first proper level - I just didn't grok it.

In the meantime, I've done quite a lot of CTFs, reverse engineering, binary exploitation etc. I tried again yesterday, and I'm already up to "Algiers". I guess that just goes to show that it isn't really suitable for absolute beginners like I was, unless you're very perseverant.
How developer stress happens and what we can do to fix it
Yes. I think both also proceeded by making major inroads into very small markets before expanding. Facebook in particular didn't get their first users by launching something adequate for a lot of people. They launched something that was a home run for a small group. Then they went school by school, dominating each as they went.

The truth is that each adopter makes their own decision; the more you can make something that's stellar for one person, the better a base you have to expand from.
Why California cities have an incentive to cheat under the new housing plan
Ya that's certainly a possibility. Of course, in such a situation, the curator could be fired. However, you face the same issue in any publicly traded corporation, but with even less recourse for the shareholders.

Don't get me wrong, even though i'm invested in the DAO a bit, I fully expect there will be serious disasters like this along the way. I'm not blind to how overwhelmingly likely it is that at least some people will run off with at least some of the money they get. But I do think these issues will get shaken out over time. And then we'll simply be left with: is it a good idea to let the wisdom of crowds make investment decisions? (also, likely the answer here is an emphatic: no, but it'll be interesting to find out).
While I agree with your general sentiment (a lot of the readings on this list strike me as being startup porn), there are some readings -- and these could be in a list -- that are good for an early startup founder to read in moderation.

Topics would include "fundamentals" like different ways to talk to customers or different ways to test product-market fit (possibly in a very efficient way). These may seem very obvious to people who have done them or know someone who has, but they are not obvious to a lot of people.

I will also add that once product-market fit is achieved and the business is officially a thing, there are a wide range of readings that would be useful for a (relatively) new founder. Topics would include things like sales, fundamentals of management (this topic is really not obvious or widely known to a lot of young, gifted people who are often founders of decent startups), and basics of business operations. Granted most of these things can be found on one's own, but a tight, curated list (this one does not seem to be one) would certainly have some value.

Note to the budding startup founders out there: Reading in moderation is fine. Always read for a purpose. Stay away from the startup porn -- it will take you down a path of failure.
How to turn a blog into an online business
I happen to work with someone who is still a citizen of Mexico living in the US ( there is family land in Mexico and he can't keep it and be a US citizen ) , and according to him, it's extremely complicated. The big complicating factor is probably the US War on Drugs.

But he has stories - like his brother fixed up a car nicely. There's a tax on that, and the car was simply taken, and his brother was taken to jail.

If you slosh money around in Mexico, chances are that somebody will take it upon themselves to collect it for themselves.

All this being said, Mexico itself seems to be slowly becoming less poor over time. They are, ironically, starting to have problems with people from Central and South America, both criminals an ostensibly non-criminals.

Yeah one of the dangers of AI and robots taking jobs is that they don't have any customers left as in B2C business model. They will have to do a B2B model but then all of the people out of work will damage the economy.

What about the people who got old and or sick? With all the people going poor without jobs some might resort to crimes to make a living.

The draft can only take so much of the population. But our military uses drones a lot and might use robot soldiers that share memories and kill the enemy more than humans can and don't need any training. Is it murder if a robot kills a civilian?

The general phenomenon here is very well known; just searching around for this I found stuff like "UK time use data for the period 1961-2001 do indeed indicate a reversal of the previously negative leisure/status gradient". ( https://www.iser.essex.ac.uk/files/iser_working_papers/2005-... ). But that paper is obviously more concerned with the UK than the US.

Data on this is directly available from the American Time Use Survey, if you want to tabulate it yourself -- while they do collect various data on employment status, they don't publish a summary of time use by employment status.
