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)

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.

>>1784 Neural network is not AI. Sure, it can adjust its weights and get better at doing its job. But that is its limit. It cannot rewrite itself as we do when we learn something totally new. >nobody knows what the missing piece is This. Nobody realy understand mind. Psychology is a joke.

Meta-Machine Code Anonymous 09/25/2019 (Wed) 03:50:17 No.269 [Reply] [Last]
I had a thread on 8chan's /tech/ for this program of mine and, now that I've found this place, I may as well make one here.

Featured in the image is my Meta-Machine Code targeted at CHIP-8; on display in that is a Rule 30 program I've written in CHIP-8. This is what I consider an ideal machine code development tool that I envisioned years back and have by now breathed life into.

An assembler is a lesser tool, I believe, lacking an intimate knowledge of what it targets and being a batch tool; my MMC is interactive and asks the programmer to recall little about the machine code being used, as it will explain in suitable detail all instructions it knows of; further, as programming is accomplished through instructions bound to keys, rather than to mnemonics, it's easy to simply press keys and answer questions until one learns what the keys are bound to. Invalid instructions won't be generated; an assembler will simply fail with an error. I've more recently come to believe the tool could have pedagogical worth, as one can simply learn the tool as it's used, which isn't reasonable with an assembler and its assembler language.

Here's some articles I've written concerning this tool of mine, which will give you details and demonstrations:
http://verisimilitudes.net/2017-07-07
http://verisimilitudes.net/2018-01-01
http://verisimilitudes.net/2018-08-08

The version currently available is old and out-of-date compared to what I'm using. The program is in a state where only I can really use it, for a variety of reasons. I've been wanting to write an Ada reimplementation, but I've found that the idea isn't nearly structured enough to the degree Ada requires and the Common Lisp implementation I've is a mess I've been reluctant to work on.

Simply put, Common Lisp is that language I'm most skilled with and the flexibility it provided allowed me to hang myself with tangential considerations. Wanting for a proper customization mechanism that wasn't Lisp, I thought a machine code was an appropriate mechanism to customize a machine code tool and the least arbitrary choice; as CHIP-8 lacks the power to do such a thing, however, I designed a Meta-CHIP-8 and the current implementation of the tool is a shell around this environment, with the personality of the tool being written in Meta-CHIP-8. This is, of course, a mess.

My current plan is to rewrite the Common Lisp once more in a more structured fashion and lacking Meta-CHIP-8 and I expect after that I'll have the structure necessary to translate the Common Lisp to Ada. I can still work on the primitives the Ada version needs and will use, but the overall organization of the packages and whatnot lacked the structure I thought it should have. I've also written my own terminal library in Common Lisp and this is something I've not yet published in Ada, which is another requirement down the way.

In any case, feel free to ask me any questions concerning this or other works of mine and I'll do my best to provide an answer. Now, the argument could be made this doesn't deserve a thread, but I thought this place could benefit from the activity and I'm suitably interested in it.

How can you even stand CL? As a Tcl user, Scheme looks like what Lisp should have been.
>>1559 You seem to believe I was unaware of SHA-1 being unsuitable for its purpose before I implemented it; this isn't the case. Firstly, SHA-1 is still in-use. Secondly, I figured I would implement all SHA over time and SHA-1 was a good starting point. I agonized over the design of my SHA-1 in Ada and this influenced the other two implementations; further, the basic shape of the design is very suited to the later SHAs. Do you not program purely for the learning and fun of it; the implementations of the SHAs in APL are practically worthless, but good fun to write and document. >I had to stop soon because of too much braindamage. Your "ideal machine text" is called entropy encoding, except that entropy encodingis language agnostic. This ideal machine text system of mine uses words as the fixed-length unit and not characters. It's not entropy encoding, but you didn't read enough to realize this. >>1692 Common Lisp resembles historical Lisps moreso than Scheme, obviously as it was designed to be the common Lisp. I like Common Lisp, the separate function and value spaces, and I heavily use macros for my work. I don't mind writing my libraries myself. If you ask a more detailed question, I'll give a more detailed answer. On that note, I've written a Common Lisp Style Document recently; feel free to give your thoughts on this as well: http://verisimilitudes.net/2020-02-14
