Browser request serialisation
It's beginning to be quite well known that if you want to load a lot of objects from the same web server, then they'll download faster if you give it more than one domain name (but not too many or you get killed by waiting for DNS requests), as web browsers have a limit on how many items they will download in parallel from the same host ( Read more... ) -

Some boxed-sets have multiple CDs. Imagine you're creating an API that tells you which CD a track is on. What should it be called?

Collaborative flash development
Does anyone write flash apps as part of a team? It seems that the "source" is a big binary mess of an FLA file. This means that you cannot merge changes made by different developers, basically limiting each file to only one developer at a time ( Read more... ) -
Cpan fail
I tried to install a perl module today. Ok my machine is old, but that's why I'm using cpan rather than using a package that comes the OS. First I discovered readline wasn't working in cpan. That's an easy fix right, you just do install Bundle::CPAN. Nope, it fails.

Persistent urls without page reloads
How many times has someone passed you a url to google maps, and you've clicked on it to find you're at a completely different place to where they intended you to be? Quite often you'll be at the centre of a town, or at their house. This is because they've copied the URL out of the address bar of their browser thinking that it will take you to what ( Read more... ) -

The JVM has the following code in DeleteOnExit.
static void add(String file) {
synchronized(files) {
if(files == null)
throw new IllegalStateException("Shutdown in progress");
files.add(file);
}
}
What would you expect to happen if files was null?

Share your login?
Here's a quick poll...
Some websites ask you for your login details for other sites. This is in order to do something on your behalf. Maybe it's facebook asking for your gmail account details so they can import your address book as a friends list, maybe it's a site that will email your twitter replies to you, or a website that wants to report your ( Read more... ) -
Interesting filesystems hack
This is an interesting feature that I learned from our new sysadmin. It seems like it'll be dangerous until you realise which levels of abstraction it works at ( Read more... ) -
Graze
Anyone else seen all the marketing for GrazeThey are designed to be perfect for office dwellers who want a healthy option for lunch without having to leave their desk. Clearly it's for those people who don't take a proper lunch break anyway. Now, I fall into that category. Normally I bring in left-overs from home, so I'm not the sort of person ( Read more... ) -
No, really, SimpleDateFormat isn't thread safe.
Maybe the documentation for SimpleDateFormat isn't clear enough. It was certainly a bad design decision, but SimpleDateFormat isn't thread-safe. The parse() and format() methods are not thread-safe. They appear to store parts of the date in fields within the object, so if you parse dates in several threads at a time then you might get errors, and ( Read more... )
