gThumb is a great image viewer but while it offers several ways of sharing images (Flickr, Facebook, etc.), sharing by email is not one of them. Fortunately, it offers a way to call a custom script on selected images.
This is a simple comparison of two cheap mini PCs that run Linux-based operating systems without problems (that is as long as you use a newish kernel) and that are despite the size more than capable of being work stations (not your kind of work, CAD designers).
Fail2ban is one of the ways to prevent script kiddies brute-forcing their way into your system. I find it amusing to view who is trying to get in. Fail2ban doesn’t have a way of listing old bans but it’s easy to get the information out of the logs. However, unless you are experienced, it takes a bit of time to construct a command that would provide the listing you want. I decided to come up with a simple script that would provide various listings.
KeePass is a brilliant program for password management. It’s free, works perfectly, doesn’t bound me to a certain provider that would store my password database on a server that I have no control of, and there are applications that allow me to work with the password database on my Android phone (Keepass2Android, KeePassDroid). When I switched to Linux, I wanted to keep using KeePass. If you are facing the same dilemma, here are your (two) options.
Many times in my career I’ve received a logo from a customer as a JPEG image with such bad artifacts that it was unusable in a website. Sometimes I’d manage to get it in a different format after a request but sometimes I was told that this is all they have and thus had to retouch it while dreaming of receiving it as a vector image to begin with. While receiving an image in a wrong format from a customer is not that bad (after all, they are not those who publish it), I often encounter wrong format when browsing the vast space of Internet and the people who published it should have known better that the chosen format is wrong. Moreover, I’ve even seen graphic designers to choose JPEG when PNG would be a better option.
