I am in the process of undertaking a DIYPNP project for my 1991 MX5. This new kit is based on the Megasquirt II design and won’t work with the existing Megasquirt I baseline maps.
I may try to use the 1.8L MX5 DIYPNP maps but I plan to double check these settings against the known base settings for the 1990-1993 B6 engine.

After the disappointment I received when Vista completely bombed on my aged but still functional Dell Inspiron 4100 (Pentium IIIm 1Ghz) I thought it had been pushed to the corner and I was only using it for testing new Linux distributions. Even that has recently become a chore as Gnome has become slick and fancy.
I am lending my old Dell to a computerless friend who is currently in need, and Linux was a bit daunting for them. I thought I’d try Windows 7 32bit as it seems to run just fine on my Intel Atom machine.
To be brief I’m stunned with the performance. A near flawless install (except for a XP networking driver I pulled from the Dell site). Sure it’s not the full aero experience but none-the-less a hugely impressive performance for a machine that is around 8 years old!
Whilst browsing through the Direct2Dell blog I saw that Microsoft has announced the release date for Windows 7.
This has been confirmed as a tweet from the Microsoft team and on their blog.
At work I seem to be getting a reputation of being a ‘Mac guy’ because I have decent OsX knowledge but in reality I like to have a go at all the current operating systems and I certainly like to explore technology.
I have had the Windows 7 RC1 running on a home machine for a while now and I am considering installing it on a netbook as I’ve heard it works quite well with the Atom processor.
Windows 7 already seems fairly polished with only the occasional driver issue presenting itself. Microsoft have managed to get 7 in better shape than Vista in a fairly short timeframe and I think this will be a successful launch for them despite the economic conditions.
If you haven’t already tried Windows 7 I recommend downloading it and giving it a chance.
Shawn Blanc has reviewed MarsEdit and suggests that it has outlasted much of the competition to survive in the blogging world of today.
I’ve been trialling Windows 7 RC1 over the last week.
As part of the installation it suggested that I install the Microsoft LIVE suite of free apps which appears to be designed to compete (in an incomplete way) with the iLife suite from Apple.
I’m using this opportunity to update my blog using Windows Live Writer which is a handy desktop application that allows you to publish directly WYSIWYG into Wordpress.
Apple insider has published an article that describes a computer market that is in massive decline. This is attributed to the current economic situation and the rise in popularity of Netbook computers running Windows XP. The author highlights that Apple has somehow managed to buck this trend with an extremely profitable period. Unfortunately for the industry Apple computers are still a minor player in terms of total units sold.
I noticed that with the most recent update of Cyberduck that sftp speed has been dramatically improved!
Hewlett Packard seems to have updated their HP Mini note to the new model HP Mini 1000.
Whilst the HP Mininote seemed to get rave reviews for an excellent typing keyboard and build quality, concerns were raised over the performance of the VIA processor that was apparently inferior to the Atom.
In the web advertisement that leapt up in front of me earlier it appears that this product has been revised with the new model using the Intel Atom 1.6 like it’s obvious competitor the MSI Wind. This new model also has the option of a 10″ screen in addition to the existing 8.9″ so with interest I was wondering if this machine would muscle out the MSI Wind with similar specs to match the formidable typing ability.
Unfortunately I can see a chink in the armour of this new machine even before reading further. Having access only to a smaller SSD drive or a 4200RPM hard drive it becomes obvious that the machine must be using the 1.8″ ipod-style drive as opposed to the 2.5″ standard laptop drive used in the Wind.
Obviously there is probably a battery performance reasoning behind using the smaller drive plus it would make heat and internal packaging much easier for the designers it does greatly limit opportunities for I/O performance and storage upgrading. Currently it’s not hard to put a 7200rpm drive in a Wind or even a 500GB 5400rpm drive if storage space is more important than speed.
I will be attempting to get my hands on a review Mini 1000 so I can do a side by side comparison vs the Wind and I will compare it to other similar models such as the Apple Macbook Air and Dell mini 9.
This is an increasingly full and competitive corner of the computer market. How far off are we from reaching full market saturation, or will people keep purchasing ever new models because of the low entry price?
I installed the new 2.1 update for my iPhone earlier tonight & I have noticed that the interface is much snappier & I seem to have much stronger 3g signal.

I’ve been toying with the idea of writing some iPhone apps. I’ve downloaded the SDK and played around a bit but I haven’t really created anything all that interesting. I was browsing a friends blog earlier tonight and I saw that he had helped another friend with some artwork for their iPhone project. I must say I’m very proud that they got their iPhone development off the ground and that it has been a success on the iTunes app store. My best wishes for a successful future writing for the iPhone and I hope I get cracking on it soon. 
It could just be the circle of people I hang out in, but I have been absolutely stunned at the number of people I know who have an iPhone already. For a device that was released not all that long ago it’s a pretty amazing saturation.
