This is brilliant. Everybody (who is anybody?)  has a PC or access to one. Using virtualization and this you could carry “your” pc on your keyring then slap it into your home desktop / laptop / friends PC / the machine in your holiday home / flat / hotel…

I used to use Tanden removable drive PC’s when I first worked from home. I just took the disk into the office & booted what looked like my PC. 

Imagine never being more than a fiddly bootup away from your PC - hot desking worldwide!

Virtualization saves money? Saves the planet???

Impressive figures (why does “multiplying it using industry standard metrics” worry me? but I guess it must be good even if not that good).

“According to VMware, for every server virtualized, customers can save about 7,000 kilowatt hours, or four tons of CO2 emissions, every year. (VMware said it got the figures by using the average electricity consumption of servers and multiplying it using industry standard metrics.) To date, approximately six million desktop computers and servers have been virtualized using VMware software. VMware says this has saved approximately 36.9 billion kilowatt hours of electricity each year - or more than the electricity used for heating and cooling the entire country of Denmark.”

If you’ve not come across this guy check out

http://www.ted.com/index.php/talks/view/id/245    http://www.cs.cmu.edu/~johnny/ and a whole myriad of youtube’s.

The guy makes technology fun, cool & interesting (OK you & I might have thought it was before but not everyone does!). I can forgive him his minor oversight of not costing the projector into his interactive whiteboard because he  does what I like best - misuses what he has to make what he needs on the cheap!

It even has parallels with freecycle in that he’s using communications technology to pass on information about recycled / low tech / cheap solutions.

Bob’s your mother?

I wish companies would keep their forms up to date or at least in sync. Having applied for a credit card on paper (don’t ask me why it couldn’t be done online) I then came to activate it on line. I was initially bemused when it told me my details did not match their records. Bemused because all I had entered was my mothers maiden name and my email and

a) I’m pretty sure I know what they are

b) I’m pretty sure they don’t - they never asked for either on the paper form

After a few moments of existential angst & identity crisis I just got round to being cross. I know my email address & mother’s maiden name, they don’t, how dare they tell me I’ve got them wrong!

I resorted to the phone line & a very nice lady calmed me down & asked me various questions. One of which was “what did you enter as your password or mother’s maiden name?” It transpires that the form I had saying “password” in some past or future manifestations says “password OR mother’s maiden name” . The web page quite distinctly just says “mother’s maiden name”.

Now, if you knew what I had entered as a password you’d know just how amusing it is to think of it as my mother’s maiden name & how unlikely it would be to enter it as such. However, you’ll have to use your imagination. Having got the thing sorted at last I have no intention of changing it just so I can tell the world what it was…

Slow Internet Explorer?

I’ve been having problems with IE6(*). It starts up but then hangs for up to a minute. The PC runs fine but IE doesn’t want to accept any key input.

I’ve removed the google toolbar & reinstalled it and problem gone. Google bar is really worth having but I do have to remove and reinstall it from time to time :(

(* IE7?  No thanks! Tabs? Why? If you know any reason why I would want tabs please leave a comment!)

Virtualization’s Dark Side - or stating the obvious for beginners

By Dave F in Reader

Posted in the web, thin clients, Coding, Blogs, Security, Microsoft on April 10, 2008 at 9:35 am

You sometimes wonder if in a world of management speak stating the obvious is genuinely seen as a clever thing. Over at

http://www.forbes.com/technology/2008/04/09/virtualization-rsa-malware-tech-virtualization08-cx_ag_0409virtual.html

Someone is (being paid for!) saying if malware controls the virtualization host it will have access to all the virtual machines and their data without the virtual machines knowing!!! Well I never, that’s as if someone bugs the telephone exchange you won’t find the bug on your handset and they’ll hear all the calls not just the ones on your phone.

Who’d have thought it? Well who’d have thought you could get paid for telling people something quite that obvious.

Then again someone is probably being paid for the comment “Rather than the usual pattern, where we deploy a technology and wait for it to get hacked, wouldn’t it be cool to try and secure it first?”

Wow, someone should suggest to the O/S people to try adding some security when they design things. OK, you may think Microsoft didn’t but I think you’ll find they just didn’t do it very well. They didn’t design it to be full of holes (except maybe any employees who moonlight for anti-virus companies).

And “wouldn’t it be cool”??? Surely doing the obvious is the opposite of cool, what we used to call “sensible”.

I am assuming the people designing virtualization software are putting some security in there and that it will be considerable more secure than end user systems just because it is not designed for end users. It can’t be tweaked with downloaded screen savers and won’t have clots (oops, busy, non technical people) opening dodgy emails.

 Going back to the phone exchange analogy, I hope it might be a bit harder to get in there and plant a bug - or am I being optimistic and expecting people to do the obvious (cool?) thing?

Slimming Down in the Classroom - thin clients to the rescue

By Dave F in Reader

Posted in thin clients, education on April 7, 2008 at 9:16 am

In these days of (stories of) obese students, classroom thuggery and global warming comes a story of good news on all fronts:

http://www.itpro.co.uk/news/184326/york-school-virtualises-desktops.html

This seems to be an ideal solution. Talking to teachers about IT I always hear stories of support and administration nightmares and talking to kids about IT in schools I hear of slow boots, crashes, sneaky ways of getting to play games & competitions to see who can make the machine most unbootable. Thin clients should make the support and admin easier (once the initial learning curve is mounted), be less nickable, cheaper to install & gloriously quiet & fast to boot to boot (do you see what I did there?).

One extra thing I would sugest is to use optical mice - teachers who have glued the mice shut to stop kids nicking the balls tend to find them hard to clean!

Free Faster Broadband

By Dave F in Reader

Apparently! A colleague has just changed to BT broadband and his intelligent, fault sensing modem dropped down to 500K as the optimal fault free speed. He was not impressed as he was getting around 2M from his previous ISP. However some googling around led him to the “bell wire fix”. Although your signal travels down miles of carefully twisted and balanced pair around the house it runs adjacent to the “bell wire”, an extra cable designed to provide power to electro-mechanical bells on half hundred weight bakelite telephones. This acts as an aerial and… let’s stop pretending I understand RF and just say it generally messes up your nice twisted pair of data lines.

As just about anything post 1970 doesn’t need it, disconnect it (pin 3 on the socket, pin 4 on the plug) and Robert is your parental sibling of the male gender.  Having done this (both at the master and extension socket) he is getting 3.5M - and his phones still ring. Of course this could be coincidence and I accept no liability for any damage, loss or general hassle incurred if you try it yourself - do your own googling and make up your own mind! I’m on cable so I can’t even say I’ve tried it myself.
