Wombat Upgrade

Today the order went in for a major rebuild of Wombat. Some parts will remain from the original, but overall most of the system will be replaced with more modern parts:

  • The new CPU has double the core count, higher clock speed and better features. It should be faster under both single and multi-threaded use. It should also use less electricity and be cooler.
  • The new GPU should be much faster, it's on a faster bus, and it has proprietary driver support (if required).
  • The SATA controller is more modern and should be much faster than the hard disk, the current controller is an older generation than the disk.
  • The RAM is much faster - two generations faster and there is four times as much of it.

Overall it should be faster, use less electricity, and be thermally cooler. It won't be as fast as my desktop, but it should be noticeably faster and my better half should be happy enough - especially as I shouldn't have to touch the data on the hard disk, which was only recently reinstalled.

Cold

I'm starting to get close to my target weight - only 3 kg to go according to BMI or a few centimetres according to height to waist ratio. Sadly for the past month I've not been able to get as much exercise as normal and I've hit another weight plateau.

Another strange phenomenon I'm experiencing is being cold. Normally even in mid winter I'm fine at work or home with short sleeved shirts and only on the coldest days do I need to wear a T-shirt under a regular shirt. In fact I've not worn or owned a proper vest for decades.

Last weekend I felt cold at home and put a jumper on. Something I wouldn't normally do in autumn. On Monday at work I felt cold but it was such a strange sensation that I didn't even recognise it. On Tuesday I went into M&S and bought a vest! Human fat doesn't provide the same level of insulation that blubber does for seals and whales, but it does provide some and more importantly on a diet the body down regulates thermogenesis to save energy. As I've been starving my self for 9 months to lose weight, it's hardly surprising that my body has decided that keeping warm isn't that important when I've shed over 21 kg.

Today isn't that cold - but it is pretty miserable. I've now got a vest, shirt, thin fleece and thick fleece gilet on. I even raised the temperature on the central heating thermostat up by 2°C...!

New Wombat

I realised that one of my desktop systems is now over a decade old, I bought it in 2005 and its starting to show it's age. The case and DVD drives are fine, the PSU and the hard disk have been upgraded mid-life, and there is nothing wrong with the display, keyboard and mouse. The problem is that the CPU is under-powered, there isn't enough RAM and the graphics subsystem is slow and no longer up to the job.

I've considered several option, but I think the least disruptive is a modern motherboard and faster current generation CPU. I can keep the case and most of the rest of the parts and just do a heart transplant.
