Ho hum, back up a bit today.
It looks like yesterday’s weather was an exception, as today was back to dull, grey and wet, which gave me a perfect excuse to stay in, which I did.
So, your picture today is from the National Railway Museum. This is the replica of Stephenson’s Rocket. The last time I was at the NRM, this was in one of the workshop areas, so it was nice to see it back on proper display.
Camera: Canon EOS 5D Mark III
Shutter speed: 1/640s
Focal length: 28mm
To get reasonable exposures without resorting to flash in the subdued lighting, I had the ISO set to 3200, which with earlier cameras would have required a lot of noise reduction to obtain a usable image. While I did do some adjustments in Lightroom, overt noise reduction wasn’t one of them.
And yes, it does look like there’s a man standing on top of the carriage.
 Increased overall exposure, darkened highlights to stop the big window being too bright, and brightened shadows
That little photo app I mentioned recently has now been updated in a useful way. Pictures are now saved in the Camera Roll and Photo Stream so they can be more easily saved and fiddled with. Nice. So here’s the Tardis to show it off.
For a long time, most Mac users have been able to operate quite happily without anti-virus software. Not, as Apple prefer to claim, that OS X is inherently more secure than recent versions of Windows, but because the vast majority of malware has been targeted at vulnerabilities in Microsoft software.
But as Mac sales have kept on growing, from a negligible share of the market not so many years ago to an actually quite significant share now, it was inevitable that sooner or later the malware creators would take notice.
And so they have. It’s been claimed by a Russian site that over 600,000 Macs worldwide are in a botnet. The vector for the infection is a hole in Java, which has been patched in the last few days.
There’s some information in this Sophos Naked Security blog post.
And so, I’ve decided that it’s now well past time for it, and I’ve installed Sophos Anti-Virus for Mac Home Edition on my computers. It’s free to use, and so far doesn’t seem to affect performance at all.
I’ve given the iMac and the MacBok Air a full scan, and all that showed up was a phishing attempt in an attachment to an email in the spam folder for an email account I don’t actually use. Attempting to download the EICAR test file triggered an on-access alert, so I think it’s reasonably safe to believe that it’s working.
Oh, and MUTTER.
 That’s in the last few days for the Apple version of Java. Apparently Oracle patched theirs quite some time ago.
