lawnmower trouble

Ran into lawnmower trouble today. After priming the engine and firing it up, it runs for 2-5 seconds and dies. It sounds like carburator trouble. Some links I checked out in the process, which are worth saving:

"hot pixels" in digital cameras

After playing around with my new Nikon D90, I noticed that some of my dark pictures have a red spot near upper right corner. It turns out this is a "hot pixel". Further research led me to the following interesting pages:

inline images in Gmail

Officially inserting inline images in Gmail is not possible. However, there is a workaround:
Open Google Docs in a new window, open a Word Doc. Insert the picture you want from your computer. This converts it into rich text format. Now you can click on the picture in Google Docs, Copy it, then paste it into your gmail compose screen.

Improved open-source firmware for cameras

Apparently it is possible to reflash the firmware on some cameras, and replace it with improved, open-source alternatives. See this post for more.

computing (car) mileage

I've been thinking on how best to get an accurate estimate of fuel consumption on my Honda Civic. Here is what I came up with:
  • keep a notebook in car
  • upon filling up the tank with gas:
    • fill the tank all the way up
    • note how many litres were purchased; write this down in the notebook, with today's date
    • also write down how many kilometres were travelled since last such refueling
    • reset the "fuel" distance counter
Figuring out the mileage over the distance travelled since the last refueling thus becomes trivial:
mileage = 100km / distance travelled * litres consumed
This gives you Canadian-style mileage, expressed in litres per 100km.

high-altitude ballooning in near-space

http://natrium42.com/halo/flight2/

High altitude ballooning is an emerging hobby, since price of GPS and communications equipment has gotten quite low. It is an excellent hobby for people fascinated by space flight and telerobotics and has many learning aspects — from systems design to electronics design to software engineering. There is also an exciting risk factor, namely, that you could lose your precious electronics if something malfunctions. In this project, many of my interest and knowledge areas came together. Also, I have verified that the Earth is indeed round and that space is black. — Alexei Karpenko
