You can take the same source code package that Ubuntu uses to build jq, compile it again, and realize 90% better performance.
I use jq for processing GeoJSON files and other open data offered in JSON format. Today I am working with a 500MB GeoJSON file that contains the Alameda County Assessor's parcel map. I want to run a query that prints the city for every parcel worth more than a threshold amount. The program is
| char (*__kaboom)[sizeof( xxx )] = 1; | |
| // xxx can be a variable or a data type | |
| // See https://stackoverflow.com/questions/20979565/how-can-i-print-the-result-of-sizeof-at-compile-time-in-c | |
| // Exemple of code: | |
| // char (*__kaboom)[sizeof( long long )] = 1; | |
| // GCC error: | |
| // error: invalid conversion from 'int' to 'char (*)[8]' [-fpermissive] | |
| // So sizeof(long long) == 8 |
Generally, the Git proxy configuration depends on the Git Server Protocol you use. And there're two common protocols: SSH and HTTP/HTTPS. Both require a proxy setup already. In the following, I assume a SOCKS5 proxy set up on localhost:1080. But it can also be a HTTP proxy. I'll talk about how to set up a SOCKS5 proxy later.
When you do git clone ssh://[user@]server/project.git or git clone [user@]server:project.git, you're using the SSH protocol. You need to configurate your SSH client to use a proxy. Add the following to your SSH config file, say ~/.ssh/config:
ProxyCommand nc -x localhost:1080 %h %p

| WEBrick is a Ruby library that makes it easy to build an HTTP server with Ruby. | |
| It comes with most installations of Ruby by default (it’s part of the standard library), | |
| so you can usually create a basic web/HTTP server with only several lines of code. | |
| The following code creates a generic WEBrick server on the local machine on port 1234, |
