"Because people who type all the time don't like to have their wrists twisted"
I use a regular(*) keyboard and my wrists are straight. In the home position, my index fingers are a bit more stretched than my pinky fingers to correct for the angle. I used a MS Natural keyboard around 1997, but I felt that it made my rsi issues worse. Learning about proper desk height and arm/wrist position helped much more, but back then it wasn't so common to have adjustable desks.
(*) Actually, I use a thinkpad keyboard with trackpoint, in Dvorak layout. I even attached an external thinkpad/trackpoint keyboard to my non-thinkpad docking station because I hate that hp elitebook keyboard.
Actually, i'm typing this with my right thumb on a 5-inch phone, in portrait mode... 6666... yep, right hand.
"A gun can puncture the pressure hull of the plane, and considering it's altitude, that would be both unpleasant and potentially life threatening"
That's not the real problem. A 1 cm2 hole will leak around 20 liters of air per second, which is negligible to the 500+ l/s of air that needs to be refreshed in a typical 200-passenger aircraft to keep the passengers from suffocating.
A bigger problem is that the bullet can damage electrical and hydraulic lines on the way out.
ah, but now I get so many hits on inassignee:micron non-volatile memory even for only patent (applications) that were published since 2014 that I don't know where to start...
Probably this new technology is somewhere among those, but who knows which ones...
That's because common practice is to crease a subsidiary and assign the patent to that entity. This is precisely to foil competitors who are keeping tabs on you.
Hmm, I work in the semiconductor industry (equipment supplier to Intel and the likes) and I have never noticed this. As far as I know, we apply for patents under our own name (at least the ones that I'm listed on as an inventor) and our main competitors do so, too (judging from the search reports that I get to see).
If this were a common practice, the names of the inventors must be listed, and it would not be so hard to search for inventor names that also appear on Intel patents. For a casual searcher on Google Patents, like me, this would not be practical, but the companies that maintain proprietary patent databases for professional searchers would have no problem adding special queries.
Given the amount of time that it takes to work out the details, convince management that this is a feasible idea, make litho masks, process the wafers, and build an integrated prototype device, I would expect patent applications to be published by now, 18 months after the initial filing.
But I don't see obvious recent patent applications by Intel.
Of course, $3000 is an amount that is completely disconnected from the actual costs for the publisher; $500 would be more realistic (editor communications, language corrections, handling the layout, maintaining servers). The whole point is to create more incentives to get that fee down. (I think that fee only applies to STM fields; researchers in the humanities wouldn't be able to pay such amounts anyway.)
"If you search for "debian 8 " I could get any kind of old crap, because the number eight has so many other uses like that this page was made the 8th of August 2008 or whatever."
I think you underestimate the capabilities of Google of recognizing word collocations that often occur in queries and web pages. Right now, your statement is true because nobody starts a forum thread or mailing-list subject with "fubar issue in debian 8".
If you google something like "fedora 22 nvidia", you won't see much posts dated 22th of June or whatever.
Somehow, a lot of US medical research is published as open access. I think one of the major funding agencies has simply demanded that the research must be published as OA. If all funding agencies do so, I'd expect that publishers will have to compete not only on prestige, but also on publication fees.
"Over here (NL), that's actually the rule: cyclists have to keep to the right at all times except in cases where there is a special bike lane. "
Fortunately car drivers are also trained to keep at least a meter distance when passing a cyclist. It seems that the problem in the US is that automobilists pass too closely and that because of that, cyclist claim the whole lane out of self-defense.
"At traffic lights, cyclists wait at the right side of the road even when going straight. Cars turning right have to give them right of way..."
When I took driving lessons, my teacher encouraged me to give cyclists space to run the red traffic lights such that they wouldn't be in my way by the time the light turned green.:-)
"So at night black would be best, allowing more heat to escape. Google 'black body radiation'."
Sunlight is mostly visible and near-infrared (400-1500 nm), so white materials reflect most of it. Thermal radiation out of the surface is wide-band, peaking around 10 micrometers, 10 times longer than the received radiation. (Google Wien's law) Most materials except metals are excellent black-body radiators in that wavelength range. No need to use black paint.
4600 micro sats sounds to me like even more junk waiting to happen. Keep it up and we'll not be able to have any nice things in orbit soon.
TFA: "low earth orbit â" in a range between 160km and 2000km in altitude."
At least the lower end of that range (up to 400 km) shouldn't be a problem. Air drag will slow down the sats until they burn up in the upper atmosphere.
in 2015 you must be running unbelievably shitty old hardware to even notice any slowdown any more with the best ciphers.
Does running rsync on an Android phone or a low-end NAS qualify? I prefer to keep my backups local rather than in the cloud.
I've said it before: The weaknesses in RC4/arcfour are all about leaking key information in the first 256 or maybe 512 bytes of cipher stream, because that's how long it takes to scramble the internal state. SSH always discards the first 1.5 kiB, so it's not vulnerable to this kind of attack. Why deprecate it?
That [restoring random seeds] only helps if there's some stored entropy to load during boot. There generally is something to load... how much entropy it has is harder to say.
Well, I'd say that managing entropy for the PRNG is mainly relevant for network-connected servers that need to generate encryption keys all the time. I assume that the timing of incoming network packets counts towards the entropy pool.(*) There should be plenty of network packets to ensure the accumulation of at least a kilobit of entropy during the normal course of operation.
(*) I can't find any list online of linux entropy sources that are used. There is LWN: Appropriate sources of entropy, where it's argued that it's difficult to make a reliable estimate of network-originated entropy. In the comments there, it is argued that one should still use the entropy from network interrupts, even if one chooses not to increase the entropy counter.
5. OpenSSL seeds its internal CPRNG during startup and then just uses it, potentially forever, without ever reseeding. Worse, when it seeds from/dev/urandom at startup it makes no effort to check whether or not the kernel pool has any entropy to give it. It just gets some bytes and goes.
That would only be a problem if the boot scripts start up OpenSSL before seeding urandom. Are there any server distros that do that? At least CentOS 6 does it in rc.sysinit, way before the network-related stuff is started.
This article, Myths about urandom, explains why it's generally silly to worry about dried-up entropy pools. There are two scenarios where this might be an issue:
1. There is a compromise that allows an attacker to calculate the internal state of the PRNG.
1a. That could be because the PRNG is leaking information about its internal state through its output. That would be really bad, but there are no known or suspected attacks.
1b. The server is compromised in some other way. Then it wouldn't matter whether it's/dev/urandom or/dev/random; you are hosed anyway.
2. There is no 'true' entropy at all, which could happen on a server which does not store its internal state between reboots and which does not manage to gather 512 bits of true entropy-generating interactions between boot time and the first use of/dev/urandom. This would be an issue only in very specific use cases, certainly not as generic as TFA suggests.
I don't see why you doubt a priori that there is a cost saving here. A high pole is likely much more expensive than a low one since it needs a much higher stiffness in order to prevent it from swinging all the time. High poles may be a costly necessity to allow the use of high-efficiency, high-power HPS lamps and to prevent dazzling road users with bright light sources close to the horizon.
LED lamps are much easier to design for a specific light distribution than HPS lamps, so they could have kept the same number of high poles if that had been cheaper. I'm sure that the road planners actually do a cost analysis.
According to TFA, it's about the TLD: something censored from google.fr,.de is not censored from google.com, even if requested from an EU IP address. It's not about censoring search results on google.com for a for a user located in the US. It is not about where the data centers serving those TLDs are located and whether they are owned by a EU-based subsidiary or not. Google could easily serve all those TLDs from the same ip address and data center if they wanted, but that is not the point.
We can agree or not about whether the right to be forgotten is a good thing or not, but let's make sure that we understand the actual conflict between G and France. I think the French have a point here.
"As far as efficiency goes there doesn't look to be much difference at the moment between sodium vapor lights and LED lights."
Strangely your reference actually states: "For example, a 30W LED street light can often replace an 80W High Pressure Sodium lamp. The reason for this is directionality. LED street lamps are very directional and the light output is much more even then by other street lamps."
Apart from that, I suspect that HPS lights are difficult to make efficient at low light outputs, such as what you need for narrow streets and footpaths where a high-power lamp mounted high up would spill too much light outside the road.
"With charge times measured in hours, what are all the people who rent or park on a street going to do?"
In Netherlands, many municipalities offer to install a charging station (about the size of an old, coin-operated parking meter), on the street, close to your home, along with two parking spots that are reserved for electrical cars. Together with the tax breaks, this makes e-cars quite popular. You don't get a personal spot, but this way the risk of not being able to recharge is limited.
Note that the electricity isn't free: you have to use a smart card to activate the charging pole. I'm not sure what they charge per kWh. Probably a bit more than the residential rate (0.21 EUR/kWh).
Isn't the Smithsonian federally funded? Good question! Federal appropriations provide the foundation of the Smithsonian's operating budget and support core functions, such as building operations and maintenance, research, and safeguarding the collections. Projects like Reboot the Suit aren't covered by our federal appropriations, which means we can only undertake them if we can fund them some other way. In other words, we won't be able to do this project without the participation of Kickstarter backers.
Actually I wonder why 'piquancy' or 'pungency' (like in pepper) is not considered a sixth taste. It is sensed by a specific receptor and it is triggered by a variety of compounds: various capsainoids from peppers and compuonds in black pepper, mustard/wasabi, raw garlic, and so on.

How do you typically figure out that they are "not bad" if the ads are already suppreseed?

That's because the kernel randomizes the memory addresses of all dynamically linked libraries of the 'cat' command every time you do that.
