In the directory sub window, when I use T to open a file in new tab, the following error message will occur:

The goal we want to accomplish here is, jumping to a function definition (maybe in another file,) finding out where a symbol is defined, finding out what function(s) call current function and what functions are called from this function, ALL WITHOUT LEAVING VIM.

I encountered this error when compiling glibc. The apparent cause is that bash can not deal with brackets correctly. So even a simple command like echo $(ls) will fail with the same error (command substitution).

In Chapter 5.5, there is one step that fixes the GCC's stack protection detection problem. The command is:

sed -i '/k prot/agcc_cv_libc_provides_ssp=yes' gcc/configure

Now that we can take advantage of rsync to minimize the data to transfer when backup. But it's still a little uncomfortable if we need to do this manually everyday, right? Well, cron is here to solve the pain.

Recently I do most of my work on a remote data center through a slow network connection (<100KB/sec). I usually backup my project source tree as follows. I first do make clean and also delete any unnecessary obj files to shrink the total file size, then I compress the whole source tree as a tar ball and then I use scp locally to fetch the backup tar ball to my local machine. The procedure is quite boring since I need to do this every day before I go home, otherwise the whole bandwidth will be occupied for near an hour during which I can almost do nothing.

Situation gets better when I find rsync and cron. Here is how I do automatic regular (daily) backup with them.

Sometime this error occurs that says:

"Unable to monitor file system. Please run: echo 100000 | sudo tee /proc/sys/fs/inotify/max_user_watches and restart Dropbox to correct the problem.

If you follow my previous post about ssh/scp without password, but you got this error when you try to ssh to B on A, then you need to add RSA or DSA identities to the authentication agent. A ssh-add command on host A will solve your pain.

We can use the graphicx package together with the graphicspath command to specify the looking up path for pictures. A typical structure may look like this:

Now I have the script that monitoring the output of several UART devices:
