Just goes to show that the TTC is generally run by idiots… so much so that it takes an outsider to make a trip planner for their own system.

Shows the true etymological roots, or original meanings,
of the familiar terms on today’s maps of the World and Europe.   Rather humorous.

command to find any changed or added files

find / -type f -mtime 1 | more

There are numerous apps to do that kind of stuff. ‘chkrootkit’ for one, to check for rootkits. ‘afick’ is a file integrity checker that runs as a cron job, or ‘check-packages’ which is an older, simple script

Install Ossec (just run the script) and the ossec wui (copy to web document root, chmod 665 and then in /etc/group add httpd to the ossec group. Just google ossec

it will give you rootkit hunting, integrity checking, it will look through log files also for things such as brute force attacks and so on and can also use active response for active blocking. A wonderful tool and a great way to search through logs as you can search for all events related to multiple authentication failures and so on or by the alert level. A very nice tool.

I’ve been playing around with the stove design popularized at the link here:

http://ygingras.net/b/2007/6/a-better-soda-can-stove

 Design is simple, yet quite sound.   In this design, it’s press-fit, so no glues or tapes is required.   However, trying to fit two equally shaped pieces into each other takes quite a bit of practice, but eventually does work.   Also, although the pieces may fit, there might still be a tiny air gap that allows for fuel to escape downwards between the pressed-fit pieces…   probably not a huge safety issue, but I have observed this happening in one of my stoves.

One issue that people have not answered was whether the stove will work in cold weather.   In my tests… depends on the temperature.   In minus 20 deg C temps, no.   After priming, the flames from the stove is not hot enough to keep the walls of the stove warm enough to pressurize the fuel.   It works ok in -10 deg C temps though…   however, I’m using it in a protected coffee can that shields the stove from the wind - see picture below.   The coffee can has several holes drilled near bottom (0.5 cm above bottom) to allow for oxygen to feed the flames.   One hole is set very low, so that I could ignite the priming fuel.

My initial pictures of “first light”.  Can’t remember why four pinholes are not ignited…  probably because I didn’t put enough fuel in.   But for my initial tests, I wanted to be on the safe side and not have too much fuel, just in case it explodes.

Stove is inside a coffee can wind shield.   Coffee can has been perforated with holes around 1 inch from the bottom, at 1-2 inch intervals.   Perforations are very important if you’re planning to use a coffee can wind shield as it allows a flow of fresh oxygen to enter.   Now that I think about it more, I should’ve put perforations onto the top of the can too, to allow for exhaust gases to escape.

Better angle of ignition hole for the priming fuel.

Boiling water on top of coffee can wind shield

Example below is of the stove in the unprotected configuration heating up a test can.

and also heating up a test tin foil container with approximately 1 cup of water starting at 23 deg C.  At ambient room temperature of 24 deg C, it took approximately 10 minutes to heat the water up to 85 deg C:

With 35 ml of fuel, I got around 15 mins of usable heating time.

This is interesting…   got a letter from my bank that they will be charging a $35 fee for my unused unsecured line of credit because I haven’t been using it.   I either start using it, or pay the fee, or close the account.   My guess is that the banks are trying to reduce the number of unsecured lines of credit on their books so that they run less risk of having unemployed people drawing on lines of credit for survival.
