Please let me know if there is a better thread to ask. I have an unused Pi3 and I would like to use it as a bluetooth receiver for a stereo. The idea bring I will plug the headphone output of the Pi3 into the input of the stereo and then the WIFE and I can stream music from our Smart Phones. Is anyone aware of a Pi-friendly distro or image that will magically "out of the box" do this for me or will I have to start with fedora and manually set it all up? It would be cool if it booted fast as piss so I can keep it off when not in use.

Hummer Driving human being posted:I was just looking around at dban to see if it had ever been updated. Why is it not good for SSDs? SSDs don't expose all of their onboard storage to the computer. They keep quite a bit of it in reserve for various reasons (and constantly shift which storage blocks are reserved or in-use) which means that even if you "fill" the SSD with random data there may still be data on the SSD in the reserved area that wasn't overwritten. In contrast, if you issue an ATA Secure Erase command to the SSD's onboard controller it will be able to securely overwrite all the data on the SSD. You can use the hdparm utility with a bootable Linux USB stick to secure erase the drive. Here is a tutorial on how to do so. Mr.Radar fucked around with this message at 20:59 on Feb 24, 2019 |

Thanks for giving me a few ideas threadMr Shiny Pants posted:Can you tcpdump the machine? Maybe it is doing something network related which went TITSUP when your fibre went down. I used tcpdump on the linux server and wireshark on a windows box at different times to see if I can spot anything obvious.
I played around for a bit, Googling and such but it was mostly just unhelpful noise because so many people have problems with basic samba config. In the end I gave up and installed debian stable, restored config files and everything is now working fine. Glad it works now but sort of annoyed I won't know the root cause, I'm not really smart enough to have kept investigating further.

Ok. I have a question. I have files in Folder A that can't be moved. I want them also in Folder B but without copying. I believe this is a Symlink? The other hitch is I can't rename the ones in Folder A but need to rename the Folder B ones. Is this even possible?

Hardlinks can be tricky to keep track of. Updating the source by truncating and overwriting the data will update the hardlink. If the file is unlinked and a new file in its place (inode changes as with say package updates), then the hardlink becomes a new file and no longer refers to the original file. Two copies of the file will exist each with different checksums. Have you looked into overlayfs? Files will retain the same names as the lower read-only layers and only duplicate when you modify them. If the files change in the original directory they'll change in your directory so long as you haven't modified the file.

Just for clarity, the difference between a softlink and a hardlink is that a hardlink isn't really a link at all: it creates another equally real name for the same underlying file. On the other hand, a softlink is more like a Windows shortcut: it's basically a magic file that contains a path. This leads to some differences. You can create a softlink to anywhere, including files on other file systems, or nonexistent ones, or even entirely invalid paths. On the other hand, hardlinks only work within one file system, and you can only make one if the target exists and is a file (as opposed to, say, a directory). If you delete a softlink, you just delete the link. If you delete the file it points to, you now have a link that points to nothing, much like a broken Windows shortcut. On the other hand, deleting a hardlink or the original is equivalent : both deletes one of the names of the file. (There no way to distinguish the "original" name). Every file has a "link count" of how many names it has, and it lives on as long as the count is above zero. (Holding a file open in a program also ups the link count, so if you delete the last name of an open file, it lives on anonymously until it's closed.) Also, see the funkiness mentioned above about what happens when you replace hardlinked files. As for "how", ln basically works like cp (the arguments are in the same order, something I've never been happy about how the manage explains). Use ln -s if you want to make a softlink; the default is hardlinks. Computer viking fucked around with this message at 00:40 on Mar 1, 2019 |

I've got trouble getting my Sega Saturn controller to work under Ubuntu 18.04. Basically it's connected to this converter that plugs into USB, and Windows recognizes it just fine. But in Linux, the d-pad sends multiple signals with one push, it's all over the place. Also it gets recognised as ""HuiJia USB GamePad", whatever that is. output from evtest if I press left on the d-pad quote:Event: time 1551771064.690346, type 3 (EV_ABS), code 16 (ABS_HAT0X), value -1 this is what happens when I press a button, for comparison quote:Event: time 1551771108.081478, type 4 (EV_MSC), code 4 (MSC_SCAN), value 90001

'HuiJia' is going to be whatever rando Chinese company made your converter, a 'USB GamePad' is presumably what it's making the controller look like (basically a USB HID device), and quite possibly it's el cheapo enough to not debounce the switches, so you would need to do that in the HID driver, and Windows does that and Linux doesn't?

Yeah, that would be my guess as well -- maybe it's debouncing the buttons in hardware but not the d-pad?

Whoa, DXVK and Wine sure seem to start going to places. I saw DXVK mentioned somewhere today and went looking for footage on Youtube. Metro Exodus, Anthem, Apex Legends, Dirt Rally 2, Far Cry Primal and so on? Seemed all relatively smooth. Will DXVK do anything for regular applications using Direct3D for rendering stuff?

I've dabbled in VTd passthrough with a Fedora host and Win10 guest in the past. A couple of weeks ago I tried the whole Proton/DXVK/Steam thing on Ubuntu (https://github.com/lutris/lutris/wiki/How-to:-DXVK) It's really, really impressive to a casual gamer like me. I found Rise of the Tomb Raider to be almost the same as Windows, Witcher 3 was great and GTA-V was very playable, with the odd graphical glitch now and then. I don't know why Canonical don't get behind it and create Steambuntu or something, to make it simplistic for the Windows crowd to download an ISO, install, use the GUI package manager, reboot and start gaming. There's also a handy site, here, for people ranking which Windows games play nicest. https://www.protondb.com/ I think that there's a good bit of variation on how people's particular systems handle certain games at the moment, but it can only get more refined as the compatibility layers improve.

Maybe it is just me but 3d acceleration on Linux doesn't feel as smooth as it does on Windows. It is the reason I am dual booting my Windows 10 installation for Blender and Unity even though they have Linux packages. Is there a sure-fire way to test if everything is accelerated as it should?

It's worth noting that the persistent problem with wine and everything after it has been it's always about one generation behind "current" if this doesn't matter to you then it seems to work fine. That said I found that pass through was a fine experience as long as you don't care about dealing with the overhead of desktop virtualization. (Not performance, but the issue of having 2 "computers" 2 sets of files, 2 oses to configure poo poo on, etc.)

One of the things that bugged me in gnome and in cinnamon was that feeling of sluggishness. KDE is much much more snappy and responsive. Or go with a light DE (openbox is as light as they can be) and try Blender. If it works nicely under a light DE then at least you know where the issues are.

So I'm messing around with using GPG for symmetrically encrypting some stuff with AES. The pinentry popup on Fedora and CentOS doesn't instil much confidence that it's grabbing a full password. Example of password with special characters in it: code: Anyone use the pinentry box for pasting passwords and can confirm that it's reliable? I mean, you encrypt stuff that's important, so you want to have faith that the password is being read correctly, right? If I use a cryptographic hash output into the pinentry box then the number of stars don't even match the password length I'm pasting in. I've proved it works by reading the password from a file when encrypting and then using pinentry for decryption, but, hmmm.
