Today is the birthday of Louis Braille, inventor of … well, braille! So as a tribute Google have replaced their usual logo with one written in braille.
Only it’s not actually braille because if you touch the letters on your monitor you won’t feel anything. Apart from your monitor. Unless you have numb fingers, in which case you’ll actually probably not feel anything. Which is what I said to start with.
To enable web users with accessibility issues to know of what the images are, all web images are recommended to include in the code a description of the image. It is this description (or “alternative text”) that screen reader software reads out to those who can’t see the images themselves.
Today’s Google logo is a good example. The alt text says:
A picture of the Braille letters spelling out “Google.” Happy Birthday Louis Braille!
While sighted viewers can see that it is a word writtein in a Braille font, and when they hover their mouse over the image it simply says “Happy Birthday Louis Braille!”, which is the
title that this image has been given.
The archive of Google Holiday Logos is quite fun. Download Braille fonts.
I’ve just ordered a couple of Corsair Flash Voyager 256MB USB 2.0 flash drives from Savastore; one for me, one for Jane.
Up until now we’ve made do with CD-R discs, or Compact Flash (CF) and Multimedia Cards (MMC) to transfer data between PCs. But a USB flash drive would certainly be more user- and environmentally-friendly. And quicker.
I was clearing out some old (3 months worth) PC magazines the other day and came across a review of 33 USB flash drives in PC Pro (October 2005). It had this to say about the Corsair Flash Voyager 512MB, which was the Labs Winner:
Lightning-fast transfer speeds make this our drive of choice. There’s no security, but the rubber casing makes it waterproof. At £26 for 512MB it’s a bargain, especially considering its ten-year warranty.
The month before in PC Plus magazine there was a Masterclass article entitled “USB Key Toolkit”. The article advised buying a flash drive of at least 256MB and packing it with tools, just in case your PC should go down and you need to reboot from the flash drive. This works with newer PCs only, as older ones can’t boot to USB devices.
Here is some of their tips:
- If you ever intend to use the USB flash drive to boot your PC, use the HP USB Disk Storage Format tool to format the flash drive with the FAT file system, rather than the default NTFS file system. (This will also allow you to specify the path of a Windows boot floppy, from which boot sector information can be gleaned and applied to your flash drive.)
- If you need to store any secure data on your flash drive, e.g. passwords, then create an encrypted virtual partition with an encryption tool.
- the essential tools they recommend you carry are:
- Scanner – visual representation of your drives
- HDDLife – monitors the temperative and capacity of drives.
- SIW – System Information application
- Autoruns – shows all the applications that autorun as you boot up Windows.
- Dustbuster – system cleaner
- Restoration – undelete application
- AdAware – anti-spyware
- Spybot Search & Destroy – anti-spyware
- avast! – Virus Cleaner
- Mozilla Firefox – browser (there is a portable version that runs from a USB drive.
- IZArc – multi-format de-archiving tool
- Save your hardware drivers and manuals on the drive
- The latest DirectX, .NET Framework (v.2.0 is out now), Visual Basic runtimes, and internet extensions such as Macromedia Flash.
- If you have the space (1GB or 2GB flash drive) then consider a CD image of Windows XP, and SP2. If you can then slipstream Windows XP with SP2.
- Include some piece of ID, on a plain text file, perhaps. And if you travel alot then also take scans of your imporant passport and insurance documents; you never know when that could be useful. Keep it on your TrueCrypt virtual drive to keep it safe.
I can’t wait. I now wish I’d ordered the 1GB drive … but maybe I can work my way up to that.
UPDATE: TrueCrypt was discontinued in 2014 due to security vulnerabilities, so I have replaced the link with an article to alternatives. (Thanks to Sophie Hunt from Comparitech for the heads up.)
