- | When I was young and dumb, I had medical research as a client. The company I worked for used to send us to all their labs in the hospitals to repair equipment. You received no safety training or equipment. The medical technicians all wore latex gloves and face masks. Even in the TB lab, you got nothing. The lab technicians worked with stool samples and weird bacterial cultures, then typed on keyboards with silicone covers – that I had to touch with my bare hands. Looking back, I realise how foolish it was, but I knew no better. Now that I am old, everyone around me gets ‘flu in winter, gets all kinds of diseases, from gout to diabetes, and, somehow, I do not. I even miss out on the common cold. The only thing I can think of is that my immune system got some tough training in my FSE years. Like one’s immune system, don’t be afraid to tackle difficult problems, you will be rewarded in the end. | + | When I was young and dumb, I had medical research as a client.

- | A: “Best” is subjective. You did not say if you want to convert to or from H.264. You also did not say if you want to re-encode or not. You also did not say if you prefer the terminal or a GUI. If you want to use a GUI, let me suggest Handbrake. Handbrake can also be used on the command-line (handbrake-cli). The other option I can give you is FFMPEG. There are also front-ends to FFMPEG.

A: There is no way to upgrade from vanilla Ubuntu to an Ubuntu ‘flavour’. You can upgrade, then switch desktop environments. There is one caveat; the desktop environment you switch to will be the vanilla one, without the tweaks the developers of that distro put into it. If you want to switch to Ubuntu Budgie, my advice is do a backup of your data and do a fresh install. | A: There is no way to upgrade from vanilla Ubuntu to an Ubuntu ‘flavour’.

A: The cache thing does sound plausible though, but I would have to go with the drive you did not format. I am not saying you have a virus, I am saying that it was probably formatted in FAT or NTFS. (Though it is always a good idea to format your drives from your supplier.) Windows file systems do not preserve permissions and are not case sensitive. You would probably have to chown all the data you copy across. Things like .rc files will prevent you from starting the GUI correctly if they are not owned by you. There will be manual work required. | A: The cache thing does sound plausible though, but I would have to go with the drive you did not format.
