atom editor linux install
lab :: running github's open source text editor
atom is a "hackable text editor for the 21st century" created by the team at github. it's designed to be customizable, but also usable without needing to edit a config file.
this quote really sums it up perfectly:
because we spend most of our day in a text editor, the single most important feature we wanted in an editor was extensibility. atom is built with the same open source technologies used by modern web browsers. at the core of atom is chromium, the open source project behind google chrome. with that comes all the power and innovation being developed for the web. but more importantly, extending atom is as simple as writing javascript and css, two languages used by millions of developers each day.

cron jobs
lab :: automating tasks in linux
cron jobs are automated scripts that run at a specified date/time, or on a specified interval.
anything that can be executed in the terminal on the server can be run as a cron job (this includes commands, applications, scripts, etc).
crontab is the command used to create/view/modify/remove cron jobs.
- crontab -l lists all scheduled jobs
- crontab -e allows you to edit jobs
- crontab -r will delete *all* your active jobs!
once the crontab file has been edited the cron daemon will automatically read it and update it's job que to match the file. you should see the message:
crontab: installing new crontab

SQL select into statement
code :: copy and swap database tables in MSSQL
have you ever had a database table that you needed to clone? you can use any number of convoluted methods such as: manually coping and pasting rows in the database manager, running lots of queries/stored procedures, or writing a script to cycle though each row copying data from one table to the next. all of these methods are inferior and far more complex then the method i'm going to show you.
introducing the select into query...
this method should be used if the table you want to clone exists, but the new table douse not. the select into query will create the new table for you, copying all the column names, properties, and data. if you want to make an exact clone of the table you can select * into the new table. but if you only want a few specific columns, you can declare only the ones you want. the syntax is elegantly simple...
SELECT * INTO [new-table] FROM [old-table]
