I spent a few hours trying to figure this out. Basically the Kindle just would not connect to my WRT160N – everything else connected fine. It just said “unable to connect to Wi-Fi network”

I tried everything – disabling wireless encryption on the router and so on. Nothing made any difference.

I decided to go for a software upgrade on the Kindle. Out of the box it had version 3.03.

I downloaded 3.1 from here, placed the file on the device via USB and then selected update from the Kindle menu.

This took about 10 minutes to run.

Following the update I was able to connect to the WRT160N with WPA encryption enabled.

Selecting a laptop to meet your needs can be a difficult task. It’s not made any easier by large IT superstores who often offer misguided advice in order to make a sale.

My position as an IT consultant has given me an birds eye view of laptop lifecycle, a continuous process where a laptop goes from birth to death. The full cycle usually takes about 5 years, which means the average human being will own about 12 laptops in their adult life.

We can draw many parallels between our own lives and that of a laptop. They come in many shapes and sizes, some are small and thin, others are fat and heavy. Some will catch diseases (malware), others will die young (hard drive failure). A few lucky ones will grow to be old and extraordinary slow.

Fortunately the life of a laptop is much less precious than that of a human. Eventually there is a strong enough driver to go and find a new laptop. Experience tells me that the first factor 95% of people consider is price. For example, a large majority of the population want to spend less than £400 (including VAT) on their laptop. Understandably, in tough economic times people want value for money, and even the big manufacturers recognise there is a market for cheap laptops.

However, the market has undergone a substantial squeeze in order to accommodate this price bracket. It might surprise you to learn that the main reason a laptop can be offered so cheap is that many large software firms have effectively subsidised it by paying the manufacturer to have their software pre-installed. This gives the software firm a foothold over their competitors. This is the reason you’ll often receive a free 30 day antivirus subscription. A lot of people will simply renew the product without shopping around. For the software firm, it only takes a small percentage of people to buy their software for the initial investment to pay off. This is just one example. Typically a cheap laptop will come with at least 10 preinstalled unwanted applications – every single one is a revenue generating opportunity for the software firm. To an experienced eye, these unwanted applications can easily removed, but usually people find it hard to identify the wheat from the chuff, and besides they don’t want to spend 3 hours removing software from their brand new computer.

The second most important (and expensive) consideration for a lot of people is Microsoft Office. Your £400 laptop certainly won’t come with bundled with a free copy. In fact you may even cry when you discover this software costs more than a quarter of the total cost of the laptop. There are cheaper Home and Student editions available, but beware these editions only contain the basic applications, such as Word, Excel and Powerpoint. For business you usually want Outlook and that comes at a higher price.

This brings us to another business based consideration. Cheap laptops arrive with a watered down version of Windows. Be warned, this will not work well with a typical business network. The reason being that Microsoft removed several features that allow the computer to be part of a business environment. Most businesses need a laptop with the more expensive Professional version.

People often overlook the core components which go into a laptop – the most significant being the processor. It’s easy to be drawn in by offers of large amounts of storage and memory. Remember that these are upgradable components, where as the processor is not. Within the sub £400 price bracket you can expect to receive a very basic processor. It will likely be produced by AMD who dominate the lower end of the market. The speed (measured in Ghz) is often advertised but this is of limited importance. This makes comparing different models difficult. Generally Intel processors offer as much as twice the performance for around an extra £100. This should be a strong consideration as it could mean the difference between a laptop which runs smoothly over it’s lifetime and one that doesn’t fulfill that dream.

In conclusion, a cheap laptop is often a false economy. The £400 laptop exists to feed a market of people who only vaguely understand what they’re buying. The truth is the cheapest laptop is unlikely to satisfy. Unless you are seriously strapped for cash, go for a more expensive laptop and you will enjoy a better experience over a longer period of time.

It’s been a long time since something was posted here, so I thought I’d post some pointless rambling. We’ve just moved the blog to a (hopefully) faster host. That’s about it.

In other news, I’ve been working on some new features for the ever popular PHP Unserializer! It will now give you the option to make changes to your data and put it back into a serialized format. Currently it only works with arrays that don’t have any sub-arrays, but I will gradually expand it to cover these too. We hope it’s of some use.

I’ve come across this one a few times now so it’s about time to post about it.

For whatever reason, it’s quite possible to end up with a Symantec AntiVirus client which isn’t talking to the server – You may have accidentally uninstalled Symantec AV from you’re server, reinstalled the server or moved it on to another server. So how do you get those SAV clients to re-register in the console?

Well, I decided to use a logon script to sort out a number of clients in one hit. Download the following av-fix batch file:

Download: av-fix.bat

In the case of SBS 2003 – you need to place this file in the netlogon folder. Once in place, open up the file and place your Symantec server name in the correct place, replacing “\\yourserver”.

To make the logon script silent, I decided to use a small program called hstart. Download it from here and place in the netlogon folder. My script uses the widely available robocopy, so get yourself a copy of that and place it in the same folder.

Now, from your main logon batch script you just need to insert the following line:

hstart /NOCONSOLE “av-fix.bat”

This executes the batch file in hidden mode (the user won’t notice anything)

The av-fix.bat file places a grc.dat in the correct place on your client machines. It also updates the pki directory.

It’s tested to work on XP (but I’m unsure about Vista…)

Sit back and watch the Symantec Console repopulate as the clients login. Beautiful! I hope you find it useful!

Just a quick note to tell those of you using RSS about the updates we have made on the website! I’ve just been playing with the PHP Unserializer (or unserialiser), hopefully making it a bit more reliable. Chances are you won’t notice the change but rest assured it is there.

Secondly, Henry has installed a new theme. It’s only one from the WordPress Themes catalogue, but a very nice one at that. We could really use a nice logo for the top left now, and possibly a change of name too?!

Normally the WAG54G2 doesn’t give very advanced ADSL line stats which isn’t much use if you’re on a fault finding mission. However, using the following URL you can get much more detailed information:

This should give you:

I’ve just realised we’ve not officially thanked our sponsors of the Royal Cornwall Show Webcam. The camera was a massive success, with over a thousand unique viewers tuning in to watch the camera pan around the grounds.

I’d like to take a moment to thank Chris & co at Kernow broadband for providing a dedicated internet connection for the camera. Stefan at Davey electrical provided his cherry picker on which we mounted the camera. Without the fantastic help of these people the camera wouldn’t have been possible!

We hope to be back next year to provide even better coverage of the grounds.

I recently installed a Windows XP virtual machine under MacOS using virtualbox, only to discover that Outlook 2007 would hang when opened (unable to connect to exchange). It seems the issue has been documented in the following ticket but no resolution has been posted. Outlook 2003 seems to works without a problem.

Update: I’ve discovered that Outlook 2007 works fine if you switch the networking options in virtualbox from “NAT” to “Bridged”. It also fixed some other issues I was having (mapped network drives and group policy didn’t get applied. For reference the domain controller is a Windows 2008 SBS server.

This year the Royal Cornwall show is taking place on the 4th, 5th & 6th of June and for the first time in the shows history, Tanist Computer Systems will be providing a live camera feed allowing you to view the show from the comfort of your desk.

The camera will be capable of panning a full 360 degrees and will be positioned some 30 feet above the showground. The live stream will be viewable for the duration of the event on www.showgroundlive.com

We hope you enjoy the show, even if you’re not there!

I was just churning through my documents and discovered a short description of my first ever snowboarding holiday with snowtrex. It’s not complete but it makes an interesting prologue.

Day 1 – Set off at 5am from Exeter, having stayed the night at Reg’s flat. I was trying to convert his Navman S30 to run TomTom – However it took 5 hours, so I didn’t actually get any sleep at all. We set off and I managed a whole 30 mins before handing over to Reg. By 9am we had made good progress, scooting around the edge of London. Then, disaster, the low oil light came on in the car. We pulled in and bought some oil for a quick top up which seemed to fix the problem. In no time at all we were queuing for the ferry. We were way to early so had to wait about an hour and a half. We finally boarded the Norfolkline – cheap but very impressive inside. We left at 12pm, The sea was flat and the crossing was very smooth. Unloading the ferry took a while and we were soon getting used to driving on the right hand side. We forgot to fit the GB sticker and headlight adapters, and passed some police looking extremely uneasy. We pulled in as quick as possible to get the stuff fitted.

We soon settled in to doing about 80mph with the cruise control on. Then a bright flash, what on earth was that. It looked like a mobile speed camera! No! I’m sure I was sticking to the limit, and I had just been overtaken by a french car going faster than me. I don’t know what it was.

Arriving at the resort we were met with stunning views of the alps. There seemed to be a major lack of toilets so we stopped to make some yellow snow. About 15 mins and we were there. It was snowing and the roads were icy. We parked up and soon found the car became stuck. We had to fit the snow chains to make any progress at all.

Check-in took a long time but we paid the 300 euros deposit and picked up the key to the apartment and lift passed no problem. We also picked up the snowboards, and paid an additional 10 euros insurance for the week. We entered the apartment and wow, it was way above expectations.

Day 2 – Very keen to get on the slopes. We soon found some green slopes and went down for our first real run. Ouch, lots of falling over and high speed crashes. I fell off the drag lift. We went back for lunch and then went for a much larger green slope. This was impressive and took about 2 hours to complete, by the time we reached the bottom we were ready to call it a day. My leg was already hurting quite a lot. We returned to the apartment and soon went out for some drinks with the polish.

Day 3 – Keen once again, this time aiming a bit higher at the Jandri express. We met up with the polish and went up Jandri 1 and Jandri 2, right to the top. Then we took the underground train to the very top. The run down was amazing, but my leg was seriously hurting and walking was very painful. Jay realised the camera had gone missing, so he went back with Reg to look for it. I stayed at the 3600 cafe and shared a jug of wine and some potato thing with the polish – yum.

We took a chair lift back up, and Kasia was super scared having never been on one before. As we got off she managed to punch me in the face and I heard a nasty cracking noise in my face. Seems like I got away without a broken nose.

We made our way down to about 2600 and then it was getting late, so we took a big cart (technical term) down and then the tiny white lifts. Reg took his board in for repair after the binding broke.
