Two or three times a year I end up needing to update my expiring SSL certificates. Each time I have to look up the one or two commands I need and every time it takes two or three websites to find the right information so I've recorded it here for future reference and in the hopes that it helps someone else as well.
Since the final release of Android Lollipop has started to roll out to devices in the last week or two many users of Dislock have noticed that it no longer removes the pin or password set on their device. I've spent a lot of time testing and trying a few workarounds, but the results are all the same, the removal of a pin, password or pattern has no effect until after a reboot. This breaks Dislock on Lollipop and most likely future versions of Android. Other apps like Dislock have also had the same problem. A few days ago I published an update to Dislock on the Play Store that restricts it to KitKat or older version of Android, specifically Dislock only supports API 14-19, Android 4.0 - 4.4.
I'm a big fan of 500px, from time to time I post my photos there and I'll happily spend hours looking through the amazing photos that others have posted. One day I was staring at the same boring wallpaper on my phone and I thought it would be really nice to have a live wallpaper that used photos from 500px. Unsurprisingly there are several in the Play Store ranging from really bad to pretty good. I gave them a try, but I wasn't very happy with them. Several of them are freemium and most of the ones I've tried are live wallpapers and continuously use a lot of ram. It also bugged me that none of them were open source.
