CrashPlan Backup – Silent Data Corruption?

Monday, April 12th, 2010

If you are using CrashPlan as one of your backup solutions, you may want to fully read this blog post and then go on to fully read the related thread on CrashPlan’s user forums.

If you are using CrashPlan as your only backup solution, then you absolutely should follow the links above.

There are some serious questions being asked at CrashPlan by users of the service.

[Update: Note that as of 7th May 2010 this has never been satisfactorily resolved or explained. Crashplan are still evasive as to the possible cause of the failed restores, in my opinion. Due to this I personally have completely stopped using Crashplan on all of my systems. See the updated original blog post and the forum thread for the entire story.]

Gadget: Logitech Notebook Headset

Logitech Premium Notebook Headset

Logitech Premium Notebook Headset

A note, rather than a review.

I have been looking for a good headset for a while. I had several specific requirements; it had to have high quality sound (both input and output), it had to be small sized enough to be easily portable, I wanted at least two connection options, one of which had to be USB, and it had to be truly ‘plug and play’ rather than ‘plug and pray’.

I have now found one that fits the bill, and the ‘Logitech Premium Notebook Headset’ is it. It’s neither new out, nor inexpensive, but it does do exactly what it says on the box.

A few major details;

  • Noise Cancelling.
  • Rotating Mic.
  • Folds Flat.
  • Travel Case.
  • Adjustable Behind-the-Head Design.
  • Soft-Touch.
  • Analog-to-USB Adapter.

A fuller review, along with some user comments, can be found over on Notebook Review.

Good headset. Recommended.

Nokia Ovi, Now With Mail

Monday, February 16th, 2009

Nokia have just opened up the beta of their Mail on Ovi service to everyone. Previously only available on Nokia mobile devices, this now adds a full web interface.

Mail is the latest service to be offered by Nokia’s Ovi suite of online and mobile applications, all of which work seamlessly between Nokia high-end devices and Ovi on the web.

I use all of the services almost constantly and, if you can ignore the odd beta glitch at this stage, they range from being extremely useful (‘Contacts’, ‘Sync’ and ‘Calender’), to incredibly flexible (‘Share’ – unlimited media storage with highly effective, finely grained sharing options), to being so well done that it is downright spooky (the ‘Maps’ cellphone application if you add the – not free – ‘Drive and Walk’ voice-guided satnav. You have to use it to believe it as it’s mostly so accurate that it is genuinely eerie).

Generally I am not a fan of handing out free publicity to big companies on this blog, or any other blog, but I am quite happy to publicise Ovi.

Great services, and they only just got started.

The Ovi service faqs are here and they are worth looking at.

All Ovi services, by the way, other than ‘Files’ on the web and the ‘Drive and Walk’ add-ons for ‘Maps’ on mobile devices, are free.

I just hope that they do not go on to somehow screw all of this goodness up.

OS X Security Update 2009-001

Saturday, February 14th, 2009

As much a note to myself as anything else, Mac OS X Security Update 2009-001 is available and should be installed.

At the time of posting I have the notification showing in software update, but I have not yet run it as after reading this post regarding a few startup problems caused by the update I think I might just hold off for a couple of days to check that nothing too untoward is likely to happen*.

*I have never yet had a problem with a security update in all of the years that I have been doing them, but there is always a first time for everything, as they say.

Pointless Tech: The Walls Have Ears?

Friday, February 13th, 2009

There’s a curious article on the BBC’s news website today about CCTV in Glasgow, Scotland that has the ability to listen;

Security cameras have long been a fact of Scottish life, viewed with relief by many communities and with suspicion by civil libertarians. But what if they were listening to you as well?

Scary. However, the article goes on to say;

A Dutch company called Sound Intelligence carried out a two week long trial in a busy city centre street. They stress that their system, called Sigard, does not record conversations. It listens not to what is being said but how it is being said.

Ok, so that’s slightly less scary, if you believe it, but where this entire idea really (and thankfully) falls apart is here;

[A spokesman for the company...] Bram Kuipers demonstrated this by clapping his hands. A display screen noted the sounds but took no action. Then he shouted aggressively. This time an alarm sounded and a CCTV camera spun round to look directly at the source of the shouting.

It will not work in reducing serious street violence, and here is why. I was born and spent the first thirty years of my life in London, ergo, I can speak with far more authority on the subject of street violence than anyone making lamposts with ears in a Dutch field full of tulips, and here are a couple of things that we learn really young in London;

  1. People who shout a lot in the street are almost always of little real threat. They are using up their aggressive energy in the act of making an unholy noise, and therefore are likely to be easy to deal with if they get out of hand physically. Usually they are either very young, or very drunk, or both.
  2. The most effective, and by far the most dangerous, violence on the streets comes from people who have thought quietly about what they are intending to do before they suddenly, and usually almost silently, do it.

So you see, the probably extremely expensive camera with ears will have a look at a shouty-but-harmless sixteen year old who has drunk way too many pints, and probably catch the last few seconds of him falling over, all by himself, dead drunk onto the ground. It will not look, though, as a truly dodgy geezer quietly walks up to his target and knifes him.

Pretty pointless then, no?

Then of course we have the real life situations;

Lets suppose this tech spreads out all over the UK. Then one day Jock comes down to London for the weekend. Goes out on the booze and ends up at a bus stop next to a bunch of drunken teenagers who hear his accent and decide to take the mickey (it’s always a bad plan, by the way, to take the mickey out of drunken Scots, it does terrible things to your life-expectancy). So Jock, used to the mean streets of Glasgow says; “Ah, will ya be quiet ya wee kiddies”, and looks innocent until the camera turns away.

Ok, so remember this bit?

Then he shouted aggressively. This time an alarm sounded and a CCTV camera spun round to look directly at the source of the shouting.

So the camera will see the mouthy kids giving Jock some verbal grief. All well and good. But then comes this;

Bram Kuipers demonstrated this by clapping his hands. A display screen noted the sounds but took no action.

You see Jock is not stupid and he like any Londoner will know CCTV well, and as we can see above the camera, once it has looked away, will not look around again as Jock decides to exact his revenge on the mouthy kids by quietly slapping them around a bit.

And Jock will know this.

I rest my case. This tech will not work.
