QTDDTOT Anonymous 09/04/2019 (Wed) 19:39:45 No.66
In a desperate attempt to get this /tech/ board going, Lets have a "Questions That Don't Deserve their own thread" thread. I'll try to answer anything I can, and I'm sure there are other people here with more know-how than me, who can help as well. Conveniently, That leads to the first question: Does anyone here have any experience with the transmission-daemon? I've gotten everything set-up for my local server, but I'd like to move all of my currently running torrents to the daemon without adding each torrent file or magnet individually. Is there any way to do this? or a place where currently running torrents are stored?

>>2632 ><Cannot add PPA: This PPA does not support bionic. There's a clue. Bionic isn't part of Mint, but rather Ubuntu. You have to go and change the repository information. It's been a while, but I think it's in an app called 'Software Update'. Just look in the menus. There's a set of files you can edit directly but I don't remember what they're called atm.

>>2635 How can I clean my SSD completely then? After installing Ubuntu it changed the boot to UEFI and now I have to press F8 on startup to switch to Windows instead of just using the grub menu. That still remains now after overwriting it.
>>2636 If you're trying to dual-boot, you'll probably just have to live with it. And UEFI settings can usually be changed in the BIOS except for the kiked machines from HP & others that lock it down. If you're willing to wipe the SSD entirely (recommended) then just do it during the Mint setup from a live usb stick. Just be certain which drive is which before you wipe it, or you'll lose Wangblows entirely probably a good thing, but w/e :^).
>>2637 >If you're willing to wipe the SSD entirely (recommended) then just do it during the Mint setup from a live usb stick. Can that be done from a DVD?
>>2638 Sure, just like with a usb stick. DVDs are rare these days. Just so long as you can burn the Mint ISO to the DVD and then boot from it instead of the hard disk you're golden.
>>2638 btw, i'd recommend you use etcher if you decide to go with a usb stick, anon. https://www.balena.io/etcher/

>>2639 Welp, tried to wipe out what was left on the SSD (format disk -> erase), still have the same issues I had before. And for some reason it installed linux mint on the "reserved for system" partition of my Windows 7 HDD, despite having clarified to install it on the SSD. So now I have double the trouble and files losts forever
>>2646 >not making backups Shiggy diggy. The system reserved partition doesn't hold your files, you should be able to recover them. >>2640 That's the same garbage that crashes and burns if blocked in the firewall? And with exec calls taking unsanitized user input?
>>2646 then try using gparted first to clear teh drive, then do a clean install after a reboot.
>>2646 your fault for using linux mint. use devuan or something else.

Is a partition scheme like the one shown here a sensible security measure for desktops? https://wiki.gentoo.org/wiki/Filesystem/Security#Mount_options # <fs> <mountpoint> <type> <opts> <dump/pass> /dev/sda1 /boot ext4 noauto,nouser,noatime,ro 1 2 /dev/sda3 / ext4 noatime,nouser,ro 0 1 /dev/sda2 none swap sw 0 0 /dev/sda5 /usr ext4 nodev,nouser,noatime,ro 0 3 /dev/sda6 /opt ext4 nodev,nouser,noatime,ro 0 3 /dev/sda7 /var ext4 nodev,nouser,noexec 0 3 /dev/sda8 /tmp ext4 nodev,nouser,noatime,noexec 0 3 /dev/sda9 /var/tmp ext4 nodev,nouser,noatime 0 3 /dev/sda10 /var/cache/distfiles ext4 nodev,nouser,noatime 0 3 /dev/sda11 /var/cache/binpkgs ext4 nodev,nouser,noatime,noexec 0 3 /dev/sda12 /home ext4 nodev,nouser,noatime,noexec 0 3 /dev/md0 /srv ext4 nodev,nouser,noatime,noexec 0 3 Do those mount options increase security significantly enough to make a setup like that worth the trouble? What if it's not physical partitions but LVM instead?
>>2652 >desktop linux >security Don't bother: there's too little market to have for-profit attacks in significant numbers, trusting poorly written (or maliciously edited) software will fuck you up regardless of partitioning, keep backups and you'll be more than fine. >Do those mount options increase security significantly enough to make a setup like that worth the trouble? No. >What if it's not physical partitions but LVM instead? No difference in security terms.
>>2652 That's not a security issue in general anon, but rather a maintenance one.

So in he process of building a better pc to work from home on, currently when I work from home it's a lappy so not powerful enough. I do a lot of cg, texturing, modeling so I often have multiple programs open at once. My basic query though is r7 3700xk VS i7 9700k. Right now where I am the prices difference is nelegible to me, but looking at this video and some others i want some understanding of why the CPU usage of the r7 is so much less? I was considering an i7 until I saw this. Right now my laptop actually has an i7 but one of the biggest problems I have when working on the laptop now is CPU usage capping out when I have a few programs open which is sometimes unavoidable in what I do. Gaming is a consideration, but the 10or so fps difference is way less important to me than that cpu usage. So could anyone shine some light on this for me?

Trying to install wangblows 7 but have no PS2 mouse/keyboard. How can I get the installation to detect my USB peripherals? Looked around a bunch of forums only to get dead links and "just use PS2 lmao"

Did nyaa.si just blocked every Tor node from connecting to their website, or is it just me? I can't access it due to 403 Forbidden errors, and switching to different nodes doesn't fix the issue (like it used to).

are there any modern laptops that have a keyboard similar to the X220 or T420? Every single fucking laptop today uses a shitty chiclet keyboard that feels like shit to type on. The ones from Purism and System76 seem really nice but they all have that fucking keyboard.
I'm installing Devuan on a Lenovo L380. Usually when I get to the part where the GRUB bootloader needs to be installed I simply select the hard drive and proceed. This time, however, the options are completely different: /dev/nvme0n1 (nvme-eui.002538b58104a515) /dev/nvme0n1p2 (nvme-SAMSUNG) I'm not about to gamble on a new $500+ brick. What's the correct way to proceed with the installation?
>>2758 It just shows you that you have 2 saparate active physical storage. >Bricking while installing grub LOL, I'm not sure that's even possible.
>>2758 Check your "mount". You can switch to tty4 while d-i is running for a shell. Run "mount" to see what is mounted where. /dev/nvme0n1p2 is probably your root partition, and /dev/nvme0n1 is your main hard drive (what /dev/sda usually is). You'd want to install to /dev/nvme0n1. But again, double check.
I have bought a suspicious new hard drive. The first time I powered it on, it already made a strange high pitched noise, like a beep. Sometimes you hear it from drives when you power them on/off, but normally not repeatedly and not as loud. Turned everything off, checked the cables, noise gone. Then I tried copying data from another HDD, after around 500GB it started to hang. Everything trying to access the disk would hang too. This happened repeatedly when trying to copy large amounts of data to the drive, but after half a minute or so it would just unhang itself and return to normal. I've run 30 hours of tests on the damn thing and the only test one that wasn't successful was the one I started while it was actually hanging. But that was in Seagate's proprietary tool that just showed some error code. Everything else seemed fine. So software seems unable to find anything because there isn't really any error, it just pauses and write speed drops to 0 while the load on the drive clocks in at 100%. This happens with every cable on every port. But only when I copy from HDD to HDD. When I copy stuff from my SSD. I can copy 600GB from my SSD and everything is fine. But try copying something from another HDD an it'll hang after 20GB. What the fuck is going on? I mean I'm going to replace the drive no matter what, how would I ever trust it, but should I return it for being damaged or just return it? And also I'm worried this is some controller fuckery a new HDD can't fix.
>>2763 drive is clearly fucked, rather than create a headache for yourself trying to figure out what's wrong with it it'd be best to just RMA it and forget it ever happened.

>>2762 I'm sorry, but how do I parse the "mount" command here? I tried looking online and I found my way into tty4, but I can't find how to do whatever command you're instructing me to. All I'm getting are the typical terminal stuff for when an OS is already installed.
>>2772 He told you to type "mount" in your command line, wow. 'tty' is lke your terminal emulator where you can switch between tty1 tty2 tty3 tty4 and so on once you invoke it by pressing ctrl+alt+F1 or F2 or F3 ect. Don't tell me you don't know how to 'lsblk'?
>>2773 I'll type "mount" in ur moms command line lmao

>>2773 I did type "mount" and nothing happened. But it doesn't matter, I figured out which one it was after having to rerun the install because the machine got disconnected from the A/C adaptor. It was the non-SAMSUNG entry. >Don't tell me you don't know how to 'lsblk'? Most people aren't manual thumping autists that think forcing people to memorize a bunch of cryptic keyboard polka dances is good software design. Those of us with our heads screwed on straight just want an non-pozzed OS with good defaults so that we can actually get shit done. Now how the hell do you MAC spoof with wicd network manager?
>>2776 Found it myself: https://wiki.archlinux.org/index.php/Wicd You have to stick the following in /etc/wicd/scripts/preconnect/ as a .sh script. #!/usr/bin/env bash connection_type="$1" if [[ "${connection_type}" == "wireless" ]]; then ip link set wlp2s0 down macchanger -A wlp2s0 ip link set wlp2s0 up elif [[ "${connection_type}" == "wired" ]]; then ip link set enp1s0 down macchanger -A enp1s0 ip link set enp1s0 up fi It only randomizes the MACs and not having it built into the GUI tool is niggerlicious. But at least the fix is a simple copy & paste.
Is getting an old 80s computer like a Commodore 64, etc. useful at all to learn low level and assembly programming? Would it be any different between actually buying one or emulating it?

How do I h.264 video decoding in Cemu on Wine?
