D40X Shortcomings
I’ve recently been looking at getting a new lens for my Nikon D40X. The problem with the D40X is that it doesn’t contain a motor for auto-focus in the body (like the D80 does). To get around this you have to buy the new range of Nikkor AF-S lenses that contain the focussing motor in the lens itself, but these can often cost quite a lot.
Team Collaboration
I’ve been at Huddle for a couple of weeks now and am very impressed with how things are going. There’s loads of ideas and things to do that will keep me occupied and interested for a long, long time.
If you’ve not seen Huddle it’s well worth a look. You can set up a free Huddle account with 1Gb of storage and create one workspace where you can upload files and invite others to those workspaces.
It’s very “web 2.0″ and we’re always making lots of changes. If you have any suggestions or thoughts about the product feel free to leave a comment.
Caching CSS & JavaScript using Rewrite Rules in IIS6
Recently I’ve been working on improving the caching within the website at Huddle to improve performance for users. After reading around, I found the following rules to be valuable.
- Cache your CSS and JavaScript forever (set a long, long expiry)
- Handle updates by changing the URL of your CSS and JavaScript
When caching “forever” the main problem is if you release an update to “styles.css” the browser caches the URL of that file, but won’t pick up any future updates unless the user clears their browser cache (you don’t want to have to tell people to “Ctrl + F5″). By changing the URL of the file, the browser thinks it’s requesting a new file, and your updates get applied. But how do you go about doing this without it becoming a pain to manage?
Securely Deleting Files in Ubuntu
*Update – the below article applies for installing nautilus-actions, but I have since updated my shred action.
Simply pressing delete on a file or folder won’t remove it from your hard drive. The reference will be removed from the file system but it will still exist on your hard drive until the space it occupies is used and it is overwritten. This can pose a problem as people can recover potentially sensitive information.
There’s an application called “shred” (installed by default) in Ubuntu for securely deleting files. It overwrites where the file is located many times, ensuring it can’t be recovered. Shred can be integrated into Nautilus easily using Nautilus Actions.
