I have a 1TB hard drive, but I'm not really using much of it, so when I started getting warnings about my disk space filling up, I was confused. I went and got Disk Inventory X to see what was using all this space. I found this:
I found some strange rendering issues happening with a site on IE that we couldn't replicate in our test environment. We finally found out those who were experiencing the issue were on the Active Directory for the same domain. Turns out, one of the group policies is to automatically set compatibility mode to on for everything in their domain. Turns out IE will respond to specific headers in order to forcefully define the compatibility mode to a specific version.
I have a development server I use to let users play around or load a site up with content before it goes live. On this server I have virtual hosts for each site. None of the information on these development sites are really secret, but I don't want these sites to end up on Google search results. I also don't want to add the extra complexity of having a username and password protecting the sites or restricting anything to a specific IP range.
A lot of commands for iptables work with targeting a specific rule number. To find the rule we usually run
iptables --list. Then I always forget if the rule numbers start at zero or one (it's one) and then have to manually count through the dozen or more rules I have in place. I'm never confident I'm targeting the correct rule, causing me a bunch of headaches. No iptables tutorials I ever encountered or even the iptables man page easily lets you know that you can add the
--line-numbers to display the rule number. Hopefully this will help other people out.
I often can't remember the name of a Drupal module I want to download and use. For example, I can never remember if I need to go to drupal.org/projects/google-analytics or google_analytics or ganalytics or whatever. I am also not satisfied with the search provided on drupal.org. So I figured out a way to put together a Search Engine in Google Chrome to do an "I'm Feeling Lucky" search on site:drupal.org/project. Here is the search string I used:
I've seen QR codes popping up in the last few months. When I first encountered it in the wild, I saw a 2-D barcode and thought why it was so prominent on the advertising. I've seen 2-D barcodes on other things such as my at&t bill that turns out to be some sort of reference number.
