Comment Re:Its always been like this (Score 3, Informative) 323

Citation please? beyond a few islanders that lived with abundant food surrounding them in regions with warm climates all year around I don't know of any that this is true for. In fact it used to be more common to work 365 days a year.

Here is a citation that contradicts your "common to work 365 days":

During one period of unusually high wages (the late fourteenth century), many laborers refused to work "by the year or the half year or by any of the usual terms but only by the day." And they worked only as many days as were necessary to earn their customary income -- which in this case amounted to about 120 days a year, for a probable total of only 1,440 hours annually (this estimate assumes a 12-hour day because the days worked were probably during spring, summer and fall). A thirteenth-century estime finds that whole peasant families did not put in more than 150 days per year on their land. Manorial records from fourteenth-century England indicate an extremely short working year -- 175 days -- for servile laborers. Later evidence for farmer-miners, a group with control over their worktime, indicates they worked only 180 days a year.


Comment Electrics Cargo Ships (Score 1) 346

Why don't we make electric cargo ships first?

Cargo ships release a huge amount of CO2, the only reason we don't complain is because they are efficient per ton moved. But switching them over would greatly reduce CO2 consumption. I think it would make sense to do them first since the ship designs are much much less sensitive to mass and volume relative to airplanes. Further, we have had ship based electric propulsion in the form of submarines for a very long time. Once the prise of batteries comes down I'd like to see high voltage lines to the major ports on hand to re-charge ships while the are being unloaded. Since they don't need to be charge 24/7 they would make a great place to dump excess capacity when solar/wind are producing at their maximum.

Comment Re:IPv6 SLAAC without EUI-64 (Score 1) 112

dhcpcd (which also works on BSD) has had support for this (RFC7217) for almost a year now, but it's now news when NetworkManager (Linux only) get's it?

RFC7217 has been in NM for some time. The news regarding this is that it now is upstream default for IPv6 connections when using NM 1.2.

The other feature, that is the real news, is a kind of MAC randomization feature that uses the real HW MAC for connection, but "fake" MAC's for scanning for AP's. This is also default now.

NM can also randomize and spoof MAC's like the decade old GNU MAC Changer, but it isn't default since that may give problems with connecting to certain devices and services.

Comment Re:Drug trials (Score 1) 232

I too am no doctor, but I have spent time under pain killers after surgery and if your case was anything like mine, the original source of pain became less and less intense. Like, if in the first week you would be on pain level 9 without medication, but after 10 weeks pain level would have dropped to level 5, and the required amount of morphine is the same, then you have developed some tolerance.

I had to use morphine for couple of weeks and didn't even notice any withdrawal, but what I have gathered (anecdotally) from other people who were on pain killers, when you are taken off pain medication, you do feel actual pain, but it is usually written off as a /just another pain episode/, after a while it gets better so who cares.

> and our Calvinist morality and repressive drug control regime hates this

Oh please! Problem with all current pain killers is that they are NOT EFFECTIVE for chronic pain. Opioids require ever bigger dosage to get the same effect, and your plan to "monitor their therapies" just mean that if the source of the pain is not dealt with, treatment will not be effective. But sure, blame Calvinists.

"Yes, they are refugees."

Isn't it odd how as a percentage there are so few women, children and old people along with these 20 something male "refugees". .

You are an idiot or come from a family that would decide to send grandma onto a rubber boat crossing the Mediterranean and into a foreign country, instead of their most capable young male.

Comment Re:Also, see the A-10 (Score 2) 290

I think most pilots would prefer to not be shot at all.

The problem with the A-10 is it's whole philosophy is low and slow. You can't build a flying tank. Sure can put some armour on aircraft, but it's a losing proposition. Armour is heavy, and heavy thing don't fly too well. It's also hard to upgrade the armour of a plane. Case in point is the A-10 which was designed to withstand the Soviets 23mm AA, to which the Soviets responded by upgrading their AA to 30mm.

This is why every other plane flies high and fast. It's why everyone is investing in stealthier planes.

Except the A-10 isn't successful at it's job, never has been.

The A-10 was designed to strafe tanks during the Cold War, but never got used for that mission. They tried to use it to attack Republican Guard tanks during First Iraq War. But the A-10 proved too vulnerable to anti-air defences and the job was given to F-16s using laser guided bombs. The majority of ground attack missions in the Second Iraq War was conducted by F-16s and F-18s. The same is true for Afghanistan. The only reason the A-10 is still around is because congress won't let the USAF get rid of it. It's never been good at its job.
