Winston Churchill's Scientists

Tim99 Re:Klaus Fuchs was one of Chruchill's Scientists.. (75 comments)

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.

Winston Churchill's Scientists

Tim99 Re:Klaus Fuchs was one of Chruchill's Scientists.. (75 comments)

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/...

Why Apple Should Open-Source Swift -- But Won't

Tim99 Re:Your post is a non-sequitur. (183 comments)

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...

Switching From Microsoft Office To LibreOffice Saves Toulouse 1 Million Euros

Tim99 Re:sure, works for France (296 comments)

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.

Court: Oracle Entitled To Copyright Protection Over Some Parts of Java

Tim99 Just try to avoid it (303 comments)

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.

Who Makes the Best Hard Disk Drives?

Tim99 Size matters? (444 comments)

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?

Oracle Promises Patches Next Week For 36 Exploits In Latest Java

Tim99 Oracle and Java What the hell happened? (154 comments)

Oracle and Java exploits - An anecdote:-
A couple of weeks ago I tried to log into my superannuation account, the browser fired back an authentication error, so I notified the company (MLC) who asked me to send them as many technical details as I could. After a little bit of looking around, I noted that the Oracle Access Management system that gave me the error code was was at version ( Oracle's currently version was Not too surprising, a supplier that had not patched to the current version.

What did surprise me was that Oracle's Identity Management Patch Set that was available for the version displayed was >2GB - A compressed Java application and framework for a database authentication application that was over 2 Gigabytes in size .

It has been a few years since I wrote any Oracle stuff, but that is ridiculous, what the hell have web based script kiddy/Java type developers been up to. Admittedly I started with Oracle in the Stone Age (V3) and actually shipped an application that used V4. By V6 the C interface which included all the necessary external validation code was small enough to be easily understood and modifiable by a single programmer. My memory is going now, but I seem to remember that in the 1990s all of the code for an early web CGI Oracle interface, including user validation would fit on a floppy.

Sorry, yes, my Google-foo failed. However as another poster has written, SWEDEN had conscription until 2010 and had a high level of their population with military training. Sweden, while not having as many guns/head of population does have a high degree of gun ownership Wikipedia Link

Microsoft Research Paper - Free Android Apps drain batteries

Tim99 (984437) writes ""Abhinav Pathak, a computer scientist at Purdue University, Indiana, and colleagues made the discovery after developing software to analyse apps' energy usage. When they looked at popular apps such as Angry Birds, Free Chess and NYTimes they found that only 10 to 30 per cent of the energy was spent powering the app's core function."

iTunes 10 borked with NAS drives & Media Serve

Tim99 Tim99 writes  |  more than 4 years ago

Tim99 (984437) writes "The iTunes 10 upgrade does not work with 3rd party daapd media servers and NAS drives:

Some respondents think that it is just a bug, but others see something more sinister:

I called apple care. Same problem...they gave me the answer as "it was not meant to be supported in itune 9 to begin with. You will have to connect it through USB drive." — (itune 10)

Hopefully this is just a bug in iTunes ann not purpose or feature of Version 10. — (Oliver D.)

Problem occurs with both Windows and OS X versions of Tunes. The fix is to down grade to iTunes 9.2.1 http://appletoolbox.com/2010/09/how-to-downgrade-itunes-10-to-itunes-9-2-1/"
