DailyWTF: Practice Makes Perfect
Rule of thumb – when you’re given 6-12 months to do a SQL server upgrade, don’t just come in one weekend and upgrade all the servers.
When Kevin returned from vacation on the day following New Year’s, he noticed an email sent from the issue tracker with the subject “Test email from SQL2005 Upgrade.” After logging in to the issue tracker server, he went directly to the manager to ask why the server was upgraded.
“Oh that,” the manager replied, “that was because I needed practice doing an upgrade.”
Dmiessler.com: Lsof
This Linux/Unix command gives you the ability to show all your network connections, show only your TCP or UDP network connections, show all the networking related to a given port, a specific host, and much more.
lsof is the Linux/Unix über-tool. I use it most for getting network connection related information from a system, but that’s just the beginning for this amazing and little-known application. The tool is aptly called lsof because it “lists open files”. And remember, in Unix just about everything (including a network socket) is a file.
I love Unix, but why is it that on one hand, you have file names like “ls” for “list” and “rm” for “remove” and “lsof” for “lists open files” and on the other hand you have names like “gstreamer-libdvd-0.3.0-1.i386.rpm.”
CodeIDE: Live Coding Interface
This is just the coolest thing ever if you’re a beginning or hobbyist programmer. Type or paste the text of your Basic, Pascal, C++, Perl, Javascript, or HTML code, and test your input and output on the web page itself.
