Re: Properly Not Linux
I'm sure you're right. Although there was literally NO software on there, that wasn't in the existing installation - we hadn't changed a thing.
I agree with you about techies on sites such as this enjoying getting their hands dirty with the inticacies of Linux - I'm the same with different tech areas - but from an outsider's perspective it was frustratingly (and surprisingly) hard to do something really quite basic!
Hi Grease Monkey
Firstly, as you say, I am relatively uninformed about Linux - I think it was version 12.04. We were very aware of the details at the time, but having moved on I couldn't swear to it now. I don't think that ought to matter though. It's version 12.x not version 0.x, and it should've worked. And believe it or not, we're not idiots - we tried lots of different things, and worked with the Cloud providers tech guys.
"with such limited knowledge should you really be installing* an OS for business use?"
Apparently not. Apparently on Linux, it requires specialist knowledge to stably share some files over a network, without the server running out of ram every 10 minutes. Windows Server seems to be able to manage it though - and I don't have any special knowledge of Windows networking either.
It seems to me that there's a tendency to glory in Linux's arcane ins and outs. Good geeky fun, no doubt - but sometimes one just wants it to work.
*For the record, we never installed Linux, it was a preexisting VM image, which had been set up by the cloud provider. As I said, all we did was share a few directories via nfs.
I saw a few "upgrade to Linux" posts here - I'm a graphics programmer, but recently our company had to set up some cloud networking type stuff. We decided to try Linux, as its instances were cheaper than those running Windows Server, and I'm always hearing how much better it is.
We couldn't make it work for love nor money. We used the default ubuntu 12 distro supplied by the cloud vendor, enabled nfs, and shared a few directories. We followed the instructions, and it all worked, but the fileserver machine kept running out of ram. Its ram usage would just shoot up, for no good reason that I could see until the machine gave up and hung. We had a swap partition, and 4GB of ram. And it wasn't under anything like a heavy load, and the only other thing it was running was an ftp client. Asked the cloud company's tech. support about it, and their best guess was a kernel bug. What a pile of arse.
Switched to Windows server in the end. I know, I know, Micro$oft blah blah. But at least it worked. At least it didn't run out of ram every 10 minutes. As I mentioned previously, what a pile of arse.
Re: Thwarted bomb attacks
All together now...
On the first day of Christmas, the NSA saved me,
From a gun toting jihadi.
On the second day of Christmas, the NSA saved me,
From two dirty bombs,
And a gun toting jihadi.
On the third day of Christmas, the NSA saved me,
From three terrorist cells,
Two dirty bombs,
And a gun toting jihadi.

Just looked like a piece of perspex to me. The '0' and '1' on the screen looked like they'd been etched in somehow - it certainly wasn't turning opaque as described.
VR immersion requires much larger field of view
There have been a few such headsets around in recent years, but they all seem to simulate a screen viewed at a distance, much as one might watch a television - a field of view of 20-30 degrees. This is a far cry from the 110-120 degree view required for the immersive experience that VR is supposed to be.
I have long wished for such an immersive display - but have never found one. Of course such a field of view would not be suitable for watching a film on, (even IMAX is only 70 degrees or so) - which perhaps puts manufactureres off. Still, games could work well - as long as the accelerometer tech is REALLY tightly coupled with the view direction!
CUDA is a tricky customer
I've had a few run-ins with CUDA, and the problem I've found is that you need to know a lot about the architecture of the card, in order to get decent performance out of it, e.g. the memory layout of a "warp" (a small batch of items to be processed), and how the card pipelines texture fetches.
I found I could easily raise or lower my performance by a factor of 4-5 by adjusting some parameters, and it wasn't clear why. I ended up just trying loads of combinations and picking the best - but then on another card, that wouldn't give good results. NVidia need to do a lot more in the compiler to abstract that stuff away.
Having said that, it was over a year ago, so things may well have improved in that regard these days.
This is, well, annoying.
Sorry to be commenting on the prose style, rather than the subject - but for some reason the use of ", well, " in written pieces has blossomed on the internet of late. It seems designed to mirror spoken language, where one might pause to think of an example to prove one's point, and use "well" to indicate what one is doing.
"I searched, well, everywhere".
"We wrote about it, well, last week".
In spoken language, this is fair enough - but writing is not done in realtime. One can pause during composition without the audience being aware of it, so there is no need for "well, errrm, aaaaand" or any of those "gather my thoughts" fillers.
Sorry to seem pedantic, but I've been noticing this a lot lately (not particularly in your fine publication, but thought I'd post here anyway). It smacks of an attempt to indicate the writer is casually confident and at ease - but writing has it's own tricks to achieve this, and writing down fake "vocal tricks" is, (well), highly lame.
(Beer icon because it's my birthday, yay!)
This comes as no surprise at all.
But then again, if I were to see video footage of Birmingham city council smearing their badly punctuated signs with their own shit, and dancing around them , screaming and grunting, it would come as no surprise.
However, that would not make it right. The apostrophe is there for good reason, and a million realpolitik, anti-elitism arguments spouted in ugly rustic accents will not change that.
We need to stop anti-intellectualism in its tracks. A pity that organisations, such as the BBC , which once might have been counted upon to take a paternalistic attitude to the maintenance of good standards regarding English language, have instead fallen under the spell of the markets, and chase ratings with Saturday night reality drivel.
