FIXME rewrite this disgraceful display of bad english writing, also consider tighting this this tl;dr crap up. Huawei dongles are pretty ubiquitous. One of our local operators (Vivo, TIM etc.) used it a lot, in a myriad of different models. Mine, particularly, is a E303C, which happens to have voice support.

If you want to, let's say, compare two VST's and the only way to get them to receive MIDI data is per via MIDI Through, you may want to use two separate ports, because nobody likes cacophony, I guess. text/html 2020-06-08T03:57:37+00:00 Anonymous (anonymous@undisclosed.example.com) http://wiki.tadeu.org/fstab-nofail?rev=1591588657&do=diff Avoiding boot failure due to missing drive As a huge e-hoarder that I am, I do happen to have multiple drives inside my computer.

To talk Odin from your Linux station, you need Heimdall. Trouble is: there's no packages for it on apt, nor there are any recent packages for recent Linux distributions.

But IPv4 seems to be on it's way out. Say goodbye to your hard typed addresses and simplicity while creating your simple network between two machines. It's the time for the bigger numbers. On what comes to possible combinations, IPv6 is not joking arround, giving enough addresses to everyone who can possibly want one through the entire universe (well, perhaps it'll run out when we reach other galaxies, but it's fine). text/html 2021-06-28T03:58:28+00:00 Anonymous (anonymous@undisclosed.example.com) http://wiki.tadeu.org/mainframe?rev=1624852708&do=diff Mainframes * Notes on how to get bloody z/VM to work on Hercules WIP * Notes on running Linux under z/VM WIP * VM/ESA as a second level to z/VM WIP * Personal notes on my OS/390 setup text/html 2020-05-29T16:12:44+00:00 Anonymous (anonymous@undisclosed.example.com) http://wiki.tadeu.org/mount-vdi-files?rev=1590768764&do=diff Mount VDI file as a drive Theres a kernel module for it, called ndb, provided by QEMU.

I've created this place so I won't forget how I did some obscure bodge six months ago, when needing to, somehow, redeploy it or explain it to a friend.
