Sometimes you find out from QA department that starting with a specific date an endpoint from your application started to work a little bit slowly
if that date is last week, or I don’t know, it happen last month, the simple solution it will be to do an export of all commit between two specific days
git log -p master@{2016-06-02}..master@{2016-06-02}
git log -p master@{2016-06-02}..master@{now}
git log -p master@{1.hour.ago}..master@{now}
for more info see this page
git-log
After I’ve installed postgresql, the problem with ‘pg’ library persisted
sudo gem install pg -v '0.11.0'
.....
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb
checking for pg_config... yes
Using config values from /usr/local/bin/pg_config
checking for libpq-fe.h... yes
checking for libpq/libpq-fs.h... yes
checking for PQconnectdb() in -lpq... no
checking for PQconnectdb() in -llibpq... no
checking for PQconnectdb() in -lms/libpq... no
Can't find the PostgreSQL client library (libpq)
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
The solution for this is to run the installer in this way:
sudo env ARCHFLAGS="-arch x86_64" gem install pg
To fix this error is very simple: you just have tot clean your node modules:
$ grunt install:development Loading "Gruntfile.js" tasks...ERROR >> Error: Cannot find module 'lru-cache' Warning: Task "install:development" not found. Use --force to continue. Aborted due to warnings. john@C370012100004 /C/projects/nodejsp(develop) $ rm -rf node_modules && npm cache clean && npm install
Useful usages of linux ssh command :
ssh -A root@www.theserveryouneed.com
If you want to forward a port to your computer from another, and you can create a ssh connection to the computer, then creating the actual tunnel is very simple.
This exemple forwards the port 7000 from that computer to a port on our computer. In this case the local port in 5000
ssh -N -p 22 user@www.server.com -L 5000/localhost/7000
