h4x   The useless ramblings of a web developer.

For a while now we’ve been banging about the office the problem of getting our website listed on google.co.uk with the ‘pages from the uk’ option ticked. The rough aim is to increase the UK traffic to www.bit-tech.net. So we bit the bullet last friday and switched the geographic target to United Kingdom in Google webmaster tools. Results will follow…  

I previously posted that I was working on bit’s new price comparison website and I can now report that it’s ready for you to use to track down the best prices.

Price comparison seems to be a popular web exercise these days. There are so many people doing it that you almost can’t google a product name without seeing at least 5 different comparison sites.

At bit-tech.net we are no different, we have our own price comparison site built from the PriceGrabber API.

I am currently overhauling the code and look and feel of the site since it looks like ass. Stay tuned for the news when it’s released later this month.

I’ve decided to make a list of all the things I don’t like about Leopard or features that I feel are missing.

1. You can’t stack or grid a saved search if you put it in the dock.
2. You can’t drag items from the sidebar to the dock.
3. Resizing finder windows when in coverflow view expands coverflow and not the dir listing

The BBC have written an article about video game driving simulators and realism. Now this would be fine had they actually featured a game that was slightly realistic rather than PGR4 which never claims to be realistic. They don’t even mention Forza Motorsport 2 (I’ll give them a point for getting GT5 in there though).

Terrible journalism.

OMG THERE IS NOT A BUG!!

Memcache has been a core part of my web programming lately and it’s one of the most flexible and useful systems ever come across.

Think for a second about the process when two people request the same dynamic page on a website. The code rendering one request has no idea that there is another request for the same page so effectively you do the whole process twice. Let’s also imagine that this request pulls a huge list of data out of a massive table that takes a while to query. In an ideal world the dbms should cache the query and the second request should be faster. In reality, and with a simple dbms both sets of data are returned in the same time. Now say one hundred other people also request that same page over the next few minutes, are we going to keep calling that data out of the database from the hard disk or is there a better way?

This is where memcache comes into it’s own. If, after pulling the data out of the database, it is placed in memory and not destroyed after the page is rendered it can be retrieved next time we want the same data. Hey presto, we can now serve thousands more requests per second as we are no longer asking for data from the database, we have exactly what we want waiting in memory.

Memcache isn’t without it’s problems, what if we change what’s in the database. Our version in memcache is now out of date. Thankfully we have set an expiry time on things that we give to memcache, so it falls out of memory after a period of time. What if your data is time sensitive? As with many things I am working on it is important that things happen at certain times rather than just waiting for things to fall out of memory. This is one problem I am currently working on and something I will cover in future.

It was only Monday that I was saying how angry I was that we weren’t going to see Haze on the xbox 360. Ubisoft had initially decided it was to be a Playstation 3 title but now it has been announced on the PC and xbox 360 and to be released only a week later! This adds to the already amazing xbxo 360 lineup set for later this year, including Assassins Creed, Bioshock and Halo 3.

UPDATE

I’ve just read that the release schedule was incorrect and the 360 release might not actually be happening. Oh well.

A story on bit-tech.net today reveals that Manhunt 2 has been provisionally banned from sale in the UK.

Now I didn’t play the first Manhunt and I don’t really want to play the second but this is a matter of principle we’re talking about here. More and more the regulatory and governmental bodies in the UK are slowly trying to wrap it’s public in a thick layer of bubble-wrap. Even speed limits are being lowered all over the country because some people forgot how to drive safely.

I think my main point is that soon no stupid people will be able to kill themselves and those that have anger issues will no longer be able to vent there frustrations in a video game, their only escape will be to go out into the street and release upon some poor soul (and I’m not talking about water sports).
