Comment: Re:Klaus Fuchs was one of Chruchill's Scientists.. (Score 1) 77

Sorry no. When Fuchs worked at Los Alamos on the Manhattan Project he was a British citizen (since 1942), although by that time he had been recruited (at least as a fellow traveller) by the Soviets; who were now allies. He was also a Quaker.

At no point was Fuchs an American citizen. As he was, at the time, perhaps the leading theoretician on plutonium implosion; it seems more logical to argue that without Fuchs it would have taken the Americans much longer, particularly as all the devices, other than Little Boy (a dead end, but relatively reliable and simple) used plutonium implosion.

It is now generally agreed that the American's curtailing of newer information to the British (from July 1942 through 1943) probably delayed the Los Alamos project by about a year, as it was still heavily reliant on Tube Alloy theory and research. The British work was heavily constrained by a lack of resources caused by waging war against Germany from 1939. Obviously the wealth, engineering expertise, and organizational ability of the U.S. were the main reason for the success of the Manhattan Project, but it would not have existed without the fundamental Tube Alloy work. Fuchs and other Soviet agents were at least partially responsible for the reduction of trust of the British by the U.S. after the war. Although U.S. nuclear test data was generally shared, relatively little cooperation occurred on fusion weapons.

No, Fuchs did not pass on information to the British.

You do know that the British worked on the Manhattan project and were working on an atomic bomb before the Americans?
See Frisch–Peierls: https://en.wikipedia.org/wiki/...–Peierls_memorandum
The early work by the British and Canadians was one reason why the Manhattan project was successful in a relatively short timescale.

Much of the material that Fuchs passed on to the Soviets came from Tube Alloys: https://en.wikipedia.org/wiki/...

The point being that Apple didn't adopt Objective-C just to be weird. Next used Objective-C to build NextStep and there's certain things in Objective-C that made NextStep moderately cool.

Objective-C was used in the late 1980s to early 1990s to quickly create relatively secure GUI environments on NeXT equipment (where cost was not a serious issue) for military/spook type applications.
This was at the time that programs written for the MS environment still were based on MS-DOS or Windows 2 or 3.0. The tools available were not generally considered suitable for the speedy development of secure systems...

Comment: Re:sure, works for France (Score 1) 296

Vacation time is not something that government can force an employer to add on top of your salary, it is your salary, it is just a different way to pay you.

I don't know for sure about France but in many European countries vacation is by law on top of your salary, so you're still getting your normal paycheck when you're on vacation. I wouldn't be surprised if this is the case in France as well.

In Australia, many employees are on a government mandated award. This has minimum salaries, overtime payments and holidays - So if you are say, a waiter or a retail assistant, you know what your minimum conditions will be.
Most awards enforce a payment of 117.5% of your salary when you are on holiday (20 days + 10 days public holidays) because most people spend more when they are on holiday.

As a now retired user and developer who sometimes used Oracle (since V4 ), I know the truth of the old saw:
Q: "What do you call Oracle customers?"
A: "Hostages"
Perhaps Larry has has read the Rentier Capitalist's Handbook and found an even better way to take all business users and developers hostage? I would advise avoiding Java (and Oracle) in new projects wherever practicable.

A few years back a rep told me that 2.5" drives were generally more reliable than 3.5" because 2.5" were designed for laptops, were they would be expected to have a hard life, and 3.5" were generally used in desktops where they would be less likely to be knocked and dropped. He said that the smaller drives reliability was was still better even when based on relative capacity (say 2x 500GB 2.5" vs 1x 1000GB). Obviously the cost differential for large amounts of storage is not favourable (except to the rep), but for home use or where reliability is important it might be worth thinking about - YMMV based on how careful you are?
