Open a file with su/sudo inside Emacs
... with emacs commands and sudo -k and then it prompts for the password. I restarted Emacs and that didn't eliminate the problem. I dug around in .emacs.d and found some references to tramp so I deleted those. Now it seems better but not sure if I'm free of it.

pip installing in global site-packages instead of virtualenv
... similarly-named test project (I had that problem, and have no idea how it started. My suspicion is running multiple virtualenvs at the same time).
If none of this works, a temporary solution may be to, as Joe Holloway said,
Just run the virtualenv's pip with its full path (i.e. don't rely on s...

A cron job for rails: best practices?
...ler
for frequent tasks (esp. where you want to avoid the Rails environment startup cost) my preferred approach is to use system cron to call a script that will either (a) poke a secure/private webhook API to invoke the required task in the background or (b) directly enqueue a task on your queuing sy...
What are the dangers when creating a thread with a stack size of 50x the default?
...e bugs. There is a counter-measure against this in later jitters, I think starting at .NET 4.0, where the jitter generates code to put a "cookie" on the stack frame and checks if it is still intact when the method returns. Instant crash to the desktop without any way to intercept or report the mis...
Logging best practices [closed]
...
e.g. The first digit can detail the general class: 1xxx can be used for 'Start' operations, 2xxx for normal behaviour, 3xxx for activity tracing, 4xxx for warnings, 5xxx for errors, 8xxx for 'Stop' operations, 9xxx for fatal errors, etc.
The second digit can detail the area, e.g. 21xx for databas...
Android: AsyncTask vs Service
... In the example above of fetching data when a button is pressed, you could start a service, let it fetch the data, and then stop it, but this is inefficient. It is far faster to use an AsyncTask that will run once, return the data, and be done.
If you need to be continually doing something in the b...
Git serve: I would like it that simple

Navigate into your project and start git-daemon with the following switches:
cd project
git daemon --reuseaddr --base-path=. --export-all --verbose
This tells git-daemon to serve up all projects inside the current directory (which I assume is the projec...
How can I change my Cygwin home folder after installation?
...
Starting with Cygwin 1.7.34, the recommended way to do this is to add a custom db_home setting to /etc/nsswitch.conf. A common wish when doing this is to make your Cygwin home directory equal to your Windows user profile dire...
How to Calculate Execution Time of a Code Snippet in C++
... @MicroVirus: yes, GetTickCount is the time elapsed since the system was started, while my function returns the time since the UNIX epoch which means you can use it for dates and times. If you are only interested in time elapsed between two events mine is still a better choice because it's an int6...
