Flink has a deadlock case and can be caused by the combination of Flink's backpressure mechanism with iterations (more likely when there is heavy feedback load).

There is a proposal to resolve this issue, but it seems to be abondoned.

The walkaround, suggested by Gábor Hermann, is to throttle messages into the iteration.

Here is my implementation.

gzip on;
gzip_http_version 1.1;
gzip_vary on;
gzip_comp_level 6;
gzip_proxied any;
gzip_types text/plain text/html text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

# make sure gzip does not lose large gzipped js or css files
# see http://blog.leetsoft.com/2007/7/25/nginx-gzip-ssl
gzip_buffers 16 8k;

How to delete a file from a Git repository, but not other users' working copies

Suppose you have, by mistake, added your IDE's project folder (you know, these .idea folders with all kinds of local paths and configuration data and settings in it) to the Git repository of your project. (We're talking about a whole folder here, but the same rules apply to individual files as well.)

Of course, you only realize that two days after the fact and have already pushed it, and your colleagues have already pulled it. They use the same IDE as you do, so whenever they change a setting or fix paths, they can either

• commit that, causing nasty merge conflicts for you and others or
• ignore the changes and carry around a modified file until the end of time without ever committing it.

Why .gitignore won't help

Why?

Useful for:

• updating current terminal's shell env proxy settings, or
• wrapping exec in .desktop files to inject env proxy settings

GNOME proxy settings should normally get propergated into the shell (bash) environment via gnome-terminal, e.g. http_proxy and no_proxy. However:

• I noticed that applications exectuted via .desktop entries sometimes don't work. This happens when an app ignores org.gnome.proxy settings but can often use proxy env vars from the shell.
• If you're proxy settings change, existing shell processes will still have the old proxy enviroment variables, so this can help refresh them whithout having to create a new shell.
