Alternative OS thread Anonymous 10/19/2019 (Sat) 21:32:41 No.480 [Reply]
Personally, I believe that *BSD (minus FreeBSD) are the most realistic alternatives for Linux.
Pls don't start spamming "blackpills" or the "cuck license" bikeshed.

OpenBSD
+ The default installation is very secure. OpenBSD has many interesting security features (pledge for example).
+ Competent developers who are committed to developing their OS
+ OpenBSD's sister projects like mandoc, OpenSSH and LibreSSl are cool
+ sndio sound server is comfy
+ Especially well-written man-pages and FAQs
+ Theo de Raadt is based
+/- Its developers and users expect you to at lest try to fix the problem yourself before they will help you. You get replies quickly on the mailing-lists. #openbsd @ Freenode is active.
+/- Doesn't have Bluetooth support anymore
+/- OpenBSD uses cvs

notes and resources
* https://www.openbsd.org/
* OpenBSD Journal: https://undeadly.org/
* Default package management: OpenBSD's ports and pkg_ tools. Currently has about 10578 packages in ports.
* The OpenBSD FAQ (the installation guide): https://www.openbsd.org/faq/index.html
* Simply put, you can use pkg_info -Q foobar to find a package and pkg_add foobar to install it
* If you want, you can install the standard Ganoo tools: pkg_add coreutils
* If you wish to run X11 (xenocara) you should also enable automatic starting of OpenBSD's DM (xenodm) during the installation
* The ability to run startx as regular user was re-added in 6.6 release, however, it is still recommended to use Xenodm as startx might pick the wrong driver in some cases, apparently
* You should install ALL file sets during the installation
* If you have (created) a (MBR or GPT) partition with OpenBSD's partition type (A6) then OpenBSD's installer will recognize it and ask whether you want to install to that partition.
* OpenBSD gaming resource: https://mrsatterly.com/openbsd_games.html
* Rundown of OpenBSD's security features: https://www.openbsd.org/security.html and https://en.wikipedia.org/wiki/OpenBSD_security_features
* You can install non-free firmware using the fw_update tool. Its man-page is self-explanatory.
* You can install patches with syspatch. Its man-page is self-explanatory.
* You can upgrade to the next release by using the sysupgrade utility, which was added in 6.5 patch no. 012. (N.B. Be sure to read the man-page as you probably want to use the -k option!) You can read more about this feature from its announcement email (https://marc.info/?l=openbsd-announce&m=156577865917831)
* The binary packages are now also getting updates on the latest "stable" release! Currently, updates for binary packages are provided on AMD64, i386 and arm64/aarch64 platforms. Previously, your only options were to either build from source or use pkgsrc if you wanted newer packages.
* If you want to install pkgsrc on OpenBSD, make backups of the original pkg_add, pkg_delete, pkg_info and pkg_check binaries. (ProTip: use whereis command and cp) Or install pkgsrc into your home directory (use ./bootstrap --unprivileged)
* I got pkgsrc working on OpenBSD 6.3 on AMD64, by using the following command-line: ./bootstrap --compiler clang --unprivileged --prefer-pkgsrc=openssl
* When you are creating disk partitions, you can specify a partition's size in (for example) gigabytes, by appending G to the desired size (for example, 42G means 42 gigabytes). (see also, man 8 disklabel, man 8 fdisk and man 8 newfs)

Anyone used Debian kFreeBSD? I'm a Debian user interested in trying out a BSD so I figure that might be a good bridge, unless it's just a novelty and I'm better off going full BSD.

ACM Library is free for a few months Anonymous 04/07/2020 (Tue) 15:12:28 No.2455 [Reply]
https://dl.acm.org/ Plenty of things worth reading on here as a supplement to books you should've gotten off libgen already. Beats picking through a poorly sorted torrent if you ask me.
>>2455 Well, that's a big surprise. Maybe LibGen is having a solid impact against publishing prisons after all. I've been a member of SIGGRAPH on and off again since school. Neat, thanks for the tip anon!
>>2470 All we need is for Sci-Hub to download them all and cache it.
>>2489 I'm wouldn't count on it as they ban IPs at the drop of a hat, and ACM's interface is slightly more useful anyway as you can browse a lot of the cited works on there. No reason to wait if you are currently out of school or work, I already got ~90% of everything relevant to my projects in the last week.

Intel Management Engine Has NSA Kill-Switch Anonymous 10/18/2019 (Fri) 12:30:31 No.468 [Reply]
>According to a highly technical blog post, Positive Technologies experts revealed they discovered a hidden bit inside the firmware code, which when flipped (set to "1") it will disable ME after ME has done its job and booted up the main processor.

>High Assurance Platform (HAP) is an NSA program that describes a series of rules for running secure computing platforms.

This is old news, but the new board needs a new reminder that until RISC-V hardware becomes readily available, no amount of free software will protect you from glow nigger spying.

>>468 > no amount of free software will protect you from glow nigger spying. Doesn't matter. NSA and most other western intelligence agencies are extremely intelligent, but clinically niggerlicious ( fortunately/unfortunately depending on your glow level) <"extremely intelligent, but clinically niggerlicious" What this? This is best illustrated via an example... Consider the following: Objective: Open door. NSA solution - spend $1bn designing advanced AI drone that turns the door handle with a laser tractor beam using telepathic remote control. Non-retard solution - Turn door handle. So although glowniggers can peek up your ass digitally it has been fuck all use because hundreds of thousands of chinky sleeper agents walked right past them and have pretty much fucked over the countries they were supposedly 'defending' from harm. Spying on your own populace makes you inherently weak.* Excessive 'Navel gazing' ensures you WILL miss exterior threats. *This will also be exploited in repercussions against (internally spying) chink commies during the upcoming (obvious) war(s). Glownigger, before you bitch about "B-but No, that's not true!" IT HAS ALREADY HAPPENED! I bet those Chinese commies are pissing themselves at parties laughing at just how useless you all are.

Libbie thread Anonymous 04/05/2020 (Sun) 17:06:27 No.2422 [Reply]
Fuck it, it's been too long since we had one and we missed the last anniversary thread. Time for more Libbieposting! I'm also sharing those Libbie folders to IPFS, since the previous uploads kept going down. I can't keep my machine on all the time though so some seeders would be appreciated. /ipfs/QmTtraPF9pcEPF7tCPMzNT67vd4gaWsCNhcaN59r5rZBXG/mascots
Is there a fork or rebrand of LibreOffice with more Libbie?

>>2460 Oh yeah and... I'll let you guys in on a little trick. If you want to get some free high quality seeders on your IPFS stuff, just download your data off of every gateway you know. Use wget to download stuff recursively within a shell script that fetches everything to /dev/null from a list of gateways or something. It's what I did. I'm not sure how often any of the gateways clean up, but I tested this by putting an image on IPFS, fetching it off cloudflare, turning off my daemon, downloading it off every gateway from a list I got from some random gateway tester github page, and it's been months and I still see multiple peers who claim to have it. I also did this but without actually downloading anything, just listing directories, with a folder with a bajillion files in it. That one is also still up.

FOSS SJW Blacklist Anonymous 09/22/2019 (Sun) 07:25:12 No.219 [Reply] [Last]
The recent shitstorm about Stallman revealed more bad actors within the Linux/FOSS community and as developers and users we should fight to regain the civilization we built with our blood and tears from the encroachment of destructive "cancel culture" madmen.

We need to start by making of list of organizations and projects that are thoroughly infested with the rot. Avoid contributing effort and support to them and eventually they will crumble inwards as internecine group politics is no replacement for hard technical knowhow.

I'll start by listing a few:

Red Hat/IBM (Fedora, Centos)
Debian
Ubuntu
GNOME
PulseAudio (Red Hat/IBM)
SystemD (Red Hat/IBM)
LibreOffice
Mozilla

Handheld Computers Anonymous 02/22/2020 (Sat) 06:22:49 No.1789 [Reply]
What is /tech/'s opinion on devices like the Smach Z and the GPD Win series and their potential for software freedom? On the one hand, having the same functionality as a laptop packed into the size of a handlend system like the 3ds could potentially let you do some pretty cool stuff. One blog I saw talked about putting Kali Linux on a GPD Win 2 and using it as a more subtle tool for wardrivng, for example. But on the other hand, they're still (((modern hardware))) so they're probably backdoored to hell and back at the very and won't be able to be 100% pozz free anytime soon absent some firmware-flashing breakthrough. Any recommendations/advice? Where I can get one firsthand in particular? I was thinking about getting one and maybe trying to install something like Retroarch on it to emulate older vidya on the go. Maybe sort through text/images/etc with /k/ and /pol/ stuff too, but that might be a bit risky w/o any idea of what kind of backdoors might be hiding. But I didn't have any luck finding anything available online the last time i tried that wasn't a secondhand offer and I'm not interested in chancing get broken shit I can't fix at a price tag of hundreds of dollars.

>>1806 it's not that simple, I've looked into it, the packaging will be hard. first, I can't find any keyboards that are just the right size. either they're miniscule, or netbook sized, not palmtop sized. Also a lot of them are bluetooth with no USB connection so you'd have to do a bunch of stuff to wire it properly. so it seems to me that at least for the keyboard you'd have to do it yourself, this shouldn't be terribly hard if you can use some perfboard or something. They have tutorials online to wire up a matrix keyboard so it's doable, you would have to source push buttons and we would have to find out what kind make the best keys for typing on. >>1894 if you're at 10" that's already a netbook size anyway so I wouldn't really call it a handheld. IMO if you could make a PC110 clone with newer hardware it would be just about perfect. one thing that sucks is all the small screens are lame 16:9 bullshit. I think making one is doable but it will take a lot of design, I don't think it's easy to throw together, at least not anything that will look and feel good.
Yeah I looked on digikey and screens are pretty expensive, usually about $40. Unfortunately they're all touchscreen garbage, but I guess with a stylus it would be alright. also, most of the ones in the 5" range are 800x480 turds. I don't even know if that is going to be usable on most websites. Maybe just barely. Unless you want to spend $160 for the 800x600 screens on there.
Why not use something similar to a raspberry pi? Are they insecure?
>>1789 I remember open handhelds were a big craze in the 2000s, shit like the Canoo and pandora. Most of those devices aren't being made anymore though, and they were almost entirely suited to playing games(no keyboard or mouse-replacement except for like the pandora).
>>2323 Try Alibaba. Chinks have all kinds of gadget and second hand screens. They should be able to modify a tiny remote media keyboard to wired at a low cost.
