This is a very valid point. We've encountered a lot of issues around this when developing Screenly (https://www.screenlyapp.com).

Firstly, do careful due diligence on the SD cards (quality between different vendors/models varies a lot).

Secondly, make sure to move all directories with frequent writes (such as /var/log) to ramdisk. This will increase the life span by a lot.
Ah, I cant criticise a marketstructure that is coinincidental for flaws because there are prices. I should criticise one market participant over another due to reasons. Got it.

Scientific journals used to haven an important role in distributing and coordinating scientific work. A large part of that reason is gone in the age of near instantaneous and free distribution.

The coordination of the process could be done cheaply and pay for a bunch more PhDs instead of a useless middleman.
True that. Enjoy those genders and plurals!!
Yep, but USB and Ethernet are on the same bus so it slows down both significantly.
> Is it creating violence or exacerbating violence?

Depends on the substance, depends on the market, depends on the reason for using. I haven't seen too many people on MDMA become violent or impoverished through addiction, though their incessant hugs and platitudes can lead to a violent response if they don't have enough to go around.

It's complex, but not that complex. We have the power of observation - where we can plot what is safe to use recreationally, what can be considered substance abuse, which substances often lead to abusive behaviour, which socio-economic factors lead to use in the first place, factors in the marketplace that lead to violence and crime, how we can monetarily/socially/legislatively abate the negative factors...and yet here we are with our proverbial junk in our hand wondering what to do. Start being objective, use methodologies that we've used for years for other problems that aren't taboo. We've travelled to the fucking moon.

My non-objective opinion: Drugs are interesting. Drugs take the edge off of a less-than-stellar life. Drugs help the mind momentarily escape the trap set by forces who care little for your happiness and wellbeing. You can fix the latter, which is unlikely in our lifetime, or reduce the burden of being a drug user in the interim.
We have some "open-source" electric car patterns, so there's a start.
That's an improvement, but it doesn't remove the animations within the text.

Also, I have this perhaps stupid inclination to use published stuff in a way that doesn't undermine the publisher's business model. This sentiment is of course a bit nonsensical if the only other option is to walk away entirely, because that wouldn't make them any money either.

as someone who might be using the Pi in a somewhat high-availability environment pretty soon, this frightens me!

What do you think is the main variable here - SD card quality? amount of I/O? or is it simply that the Pi is not meant for high availability?

If the answer leans to the latter, what other choices are there? My goals is to find a small computer (very small) that has reliable uptime and can do 1080p video.

No. Only racing bikes have those, occasionally. In Amsterdam 99% of people ride a normal bike, not a racing bike. This is the essential difference between the bike cultures. Car drivers in the netherlands also do not like like bike racers, but only a small fraction of cyclists are racers.
Yvain's classic on disease/failure of personality is worth bringing up[0].

Also, his more recent take on (US) attitude towards treating heroin addicts[1].

The ending paragraph of [1] works as a great TL;DR:

"Society is fixed, biology is mutable. People have tried everything to fix drug abuse. Being harsh and sending drug users to jail. Being nice and sending them to nice treatment centers that focus on rehabilitation. Old timey religion where fire-and-brimstone preachers talk about how Jesus wants them to stay off drugs. Flaky New Age religion where counselors tell you about how drug abuse is keeping you from your true self. Government programs. University programs. Private programs. Giving people money. Fining people money. Being unusually nice. Being unusually mean. More social support. Less social support. This school of therapy. That school of therapy. What works is just giving people a chemical to saturate the brain receptor directly. We know it works. The studies show it works. And we’re still collectively beating our heads against the wall of finding a social solution."

I don't see any problem with having Elsevier manage publications that prevent people from copying their content. Just as long as that content is also available elsewhere for free, if it's publicly funded research.

I assume the problem is that Elsevier doesn't much like when articles are also made available outside their publications? Well, then either starve them of all publicly funded content or just have them accept that all the publicly funded content will always be available outside their publications. It's as simple as that.

A proposal requiring that publicly funded research is publicly available would be how hard to pass in as law? Why aren't such proposals made? If they are, what has stopped it from already being law?
Have you ever thought why do we need competition so much?
Not only that, but in the case of MSVC/Visual Studio you have a talent feedback loop as well as a financial one. They need people to be pirating it or they'll have no windows developers in the future.
If I make a mistake on my taxes, or lets say, park in the wrong place, I get fined.

If someone does heroin and gets hooked, they get a treatment program.

What is the difference? Why, according to you, should I be punished, while the person on heroin should get all these treatment options opened up to them?

Where is my "parked my car in the wrong place" rehab program?
Yep, but that turns out to take more words than a blanket restriction.
As a german, what I often see in older generations is the attitude that work is not something you enjoy. You endure it. Suck it up and drudge. This implies you have a Feierabend after work, where you can do what you enjoy.

Younger generations have a different attitude, which I assume is spilling over from the US: Follow your passion. Find work you love to do. This implies you love to work longer hours.

I am not ruling out that the overhead of Agile maybe too expensive for some sort of tasks/jobs.

But in before-mentioned cases, accepting more responsibility wasn't considered appropriate by the individuals: Why would you want to do more work under the risk of being blamed?

Command & control structures have a great advantage: Blame goes up…
Actual SSDs have multiple memory chips in them, and not only they spread writes between them, they do actual wear leveling, so once certain cells become unwritable they are marked as such and the controller starts using cells from the reserved area(which can be few or even several gigabytes on larger drives).
SD cards on the other hand have only one chip, and although they have a controller that monitors the wear level, they have an extremely limited number of spare cells, so it's very easy to kill an SD card by repeatedly writing to the same address.

As others have mentioned - you could solve this by serving the content from a USB drive, but because Ethernet and USB share a bus, you will essentially halve the speed of each, which is not ideal. If you have the money to spend, I would recommend a different board, but with a dedicated SATA port, so you can use an actual SSD or a regular hard drive for serving content. So....TK1?

Comments above suggest that the pincode information is managed within a HSM-esque onboard hardware device. As such, extracting that chip and retrieving the pincode hash is likely to be entirely infeasible, even for very capable orgs like the NSA.

There's only so much profit in the drug business because of the illegality of many drugs. Changing that would kill the profits of many very rich and powerful criminals and cartels. So it's very understandable that those people do everything they can to prevent their business model from collapsing.

The usual way of doing it is simply lots of lobbying: Paying "well meaning" people, journalists and politicians to stay on the track of keeping most drugs illegal, so that the drug lords and cartels can continue to earn money.

So does really anybody wonder why the (obviously totally pointless) "war on drugs" is still waged and will probably waged for quite a while?

I also don't like it but the paper needs be printed and reviewed. This is not free. Perhaps we should agree that the publishing group pays for the entire cost of the article so that it can be free after the process of publishing it? Or boycot paywalled publishers, maybe go for PLOS? If you have ever complained about paywalls, don't ever publish in a paywalled journal yourself.

I'm all for free papers by the way, nothing is more annoying that researching things and hitting paywalls but someone has got to pay the people doing the publishing work.

Also: If I order a paper from our library or I download it myself, it often comes with an on the fly generated cover page with my IP address on it. One can remove that, certainly but there may be other mechanisms to tag papers. Amazon reportedly investigated (and implemented?) putting specific, unique errors in DRM free ebook copies to identify sources of piracy. So I wouldn't advice you to just send the PDF around unless you are the author maybe and have a PDF that did not go through the publishing process.

Still loving the initiative though ;)

Get your calculation right:

Assuming 100nSv per scan (first comment in this post). 10s per scan. ~4000 scans in 12h.

-> 400uSv = 0.4mSv.

Background where I live: 2mSv per year. So this is a fifth of the yearly background dose at my place. But in a single day.

For example, scan the entrance/exit of a parking garage (such as one under supervision) regularly, and you have a realistic chance of severely harming the guy at the ticket booth.

It is easy to give your money to Elsevier when your future career depends to a great measure in having Elsevier publish your research.

You may be angry but the scientist needs a future.
2.6.1 is the previous release version. 15.11 is just year.month of the next release version, apparently they are moving to a new numbering scheme.

Not sure about 4.0, but I think it was the working number for the next release (to avoid confusion with Python 3, I guess they call that pypy3 and have a version number also).

Great keyboard, nice 1080p display, trackpoint, (hot)swappable batteries and several storage options.

Yeah, I was not quite coherent with that statement: I mean that Lua doesn't require that you learn to use an editor to line things up properly, a concept which my 5 and 8 year old kids definitely have an aversion to, since it seems like trivial nonsense (to them) to have to do formatting to make code work, having cut their teeth on the BASIC of our 8-bit battlestations set up for the task.

I just mean, to a new programmer - especially a young one - having to grasp alignment/editing concept is a stumbling block, and unnecessary when languages like Lua provide all the same degree of power as Python, and less to learn to get started..
> I also don't like it but the paper needs be printed and reviewed. This is not free.

I have peer reviewed various academic papers for Elsevier without receiving any monetary compensation. Moreover, quite small amount of academic papers is read in a printed form, at least among my colleagues.

Where the money goes to?

If this really works, the only options I see are that a) it works at a massively ineffective power transfer rate or b) it is dangerous if you accidentally get in the focused beam (or c) a combination of the two). Any kind of beamforming which can get a decent power transfer will, naturally, transfer that energy into whatever is where the power is focused. Granted, uBeam claims to stop power transfer if line of sight between beamer and device is blocked, but then you are counting on a safety mechanism which is "default off" in some sense. I personally would want to see more tests than a 5 week pig trial as mentioned in the techcrunch piece [1]. After all, radium used to be seen as a "health medicine" back in the early 1900s - it was only after years we realized that radiation was really, really dangerous. It would be great to ensure that kind of thing would not happen in this case - but this means something like a multi-year trial period, which is not good for a startup.

If it is inefficient, the energy issues we already have in the world make it seem irresponsible (to me at least) to use something that operates even more inefficiently than the current system, which is already causing global problems with respect to energy consumption and generation. Even inductive chargers have efficiency issues, and it seems like converting to ultrasound and back would have some inherent loss, though it is really dependent on the quality of implementation. If they can avoid danger, and only have inefficiency issues, I could see some success here for low-energy requirement devices.

If it is dangerous, well that is pretty obvious. No one wants to slow microwave their dog/child/foot/hand if the beamforming is slightly off.

I just don't see a way for this product (or any number of other related products, or RF energy harnessing generally) to succeed without some (unknown) fundamental breakthrough or incredibly expensive hardware.

AFAIK, they were considering to change the versioning scheme because the old scheme is becoming too confusing.

The old scheme (PyPy 2.x) resembles Python 2 versioning too much (PyPy 2.6 vs. Python 2.7) and may cause confusion that PyPy version correspond to Python version it implements (while in fact it is not). Say, if the next release is PyPy 2.7, some may assume it is a PyPy implementation of Python 2.7 (even though PyPy 2.6 is already Python 2.7). The situation is also confusing with Python 3 as well (PyPy3 2.6 for Python 3.2.)

I think PyPy's initial plan was to use YY.MM for versioning, so the tentative version was 15.11 but now looks like they decided to follow the old scheme but with major version > 3 instead (so the next release is PyPy 4.0.0 and PyPy3 4.0.0).
It's interesting that we actually have a potential big opponent for the drug cartels - drug companies. Legalizing drugs will drive cartels out of business because they'd be competing with clean drugs sold in pharmacies, prepared in well-funded laboratories of entities used to cooperating with safety regulations. So why the Big Pharma isn't lobbying for ending the war on drugs?

I wonder if it isn't the social view that's blocking them - the first pharmaceutical company to step up and vote for legalization could face a serious PR shitstorm centered about morality of "legitimizing addiction".

I've had some trouble for a while with idea of "technical debt."

When I'm planning work, I can't look at something and say "I'm taking 10 points of debt with this decision, at an interest rate of 1 pt per month."

By the nature of how tools, libraries, frameworks and languages evolve, our implementation today will likely be inefficient compared to what we could build 24 months from now, may not be well-tailored to button up next to a system we haven't yet purchased/implemented, etc.

As we don't have time machines or crystal balls at our aid to predict what the future will hold, it's always seemed more helpful to focus more on how to design a solution for modular improvement. If any given component could effectively be isolated and then refactored or replaced, you can look at those issues more as continual improvement.

My experience has been that, if maintaining and continually improving existing code can be respected in the organization with the same value as new feature development, a lot of the angst goes away.
But there is a profession dedicated to preventing these kinds of failures: Systems Administrators.

Proper infrastructure engineers (or "site reliability engineers" as google now calls them) are key for helping architect highly available systems like this; Yet the trend seems to be forcing software engineers follow tutorials from google on setting up key pieces of infrastructure nowadays.
