Meta-Machine Code Anonymous 09/25/2019 (Wed) 03:50:17 No.269 [Reply]
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:

The version currently available is old and out-of-date compared to what I'm using.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.

>>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
>>1785 I mean from a consistency and elegance point of view. Both Lisp and Scheme stem from lambda calculus but Lisp departs way further and seem to complicate the syntax uselessly (e.g. ' and quote). To someone who never touched Lisp but use Tcl and did a bit of Emacs Lisp, Lisp vs Scheme distantly looks like C++ vs C; well, if you ignore the timeline and squint your eyes really hard.
>>1804 The Lisp family doesn't truly derive from Lambda Calculus. Without venturing to get an exact quote or to doublecheck, John McCarthy didn't understand all of Church's paper and used the name lambda for some reason I don't recall. The quote shorthand exists in Scheme and Common Lisp, among others. Common Lisp isn't a Lisp which is fearful of becoming more complex to simplify itself. You may think Common Lisp is complicated, but in many cases providing what it does makes things simpler, if only because there's a standard way to achieve such things. By having a mechanism for conditional compilation through #- and #+, as an example, there need not be multiple and incompatible solutions to the problem. Providing a solution to a problem, rather than ignoring the problem's existence, is valuable. I enjoy that I can easily test my libraries and programs in multiple implementations, rather than being tied to a small number and accidentally using nonstandard code where it's avoidable.
>>1813 Then the language failed. It should give you the minimum set of tools to solve all your problems by building more tools, not the world's biggest toolbox. That's why I think Tcl's uplevel is the best thing to ever happen.
I released the reimplementation on the third anniversary of the announcement: http://verisimilitudes.net/2020-07-07 This post doesn't bump, as I'm not quite certain it's worthwhile to do so. I'll still check this thread periodically for replies, however, so feel free to prove me wrong.

What's a fun interactive thing I can do with a VPS? I don't want to use it for a Tor exit node because that's not interactive and I don't want to use it for an imageboard either because that's gay. I was thinking as a site where people can just dump a message. Like a text board but without post numbers and stuff.
Run a dynamic web server (node, django, php, jsp, asp, whatever) and allow file uploads. Imagine the fun! Make sure the server stays up to date and prevent the most obvious exploits like system calls, uploading outside the site folder and .htaccess files that redirect everything to CP. Basically run metasploit against your own server and check if it's all good.

Does anyone know how to wholly replace a syslinux boot with grub2? I'm trying to load some squashfs read only live usbs but I need grub so I can pass some grub commands before the kernel loads. syslinux is A SHIT and there are no useful modules like in grub. The live images have the kernel separate from the system rootfs, and I have no problem targeting the kernel in grub, and the initrd seems useless from what I could see from the init script in it, like I could just pass flags to the kernel directly instead of fucking around with a bunch of useless if statement busybox bullshit. I managed to get it to work for one system, with no initrd and everything, but I can't reproduce it in a second system. Why is everything a fucking script and all the real commands undocumented. Anyway, I've been working at it for ages and tomorrow I'll just try the hail mary of passing grub-install to a drive with the live image written and see if it overwrites the syslinux bullshit, but I was hoping anons here might have a better idea. Also, what are the odds of getting a working system from source off github? I've never done a custom build, but I need to because I want to include some legacy drivers as well as grub. Everything seems to be automagically made with bootroot and docker but it doesn't really tell me how to build a custom version. for clarity, I have no problem getting to grub and booting the efi files, but the kernel can't find the squashfs root even though I pass the flags, so something's fucking up in my /boot/grub/grub.cfg, and yes I'm writing it by hand because I'm autistic like that.

>>1480 I'm trying to boot a kernel which uses a squashfs filesystem. I succeeded by just passing the right kernel arguments by hand in grub but there were various issues like certain kernels didn't work unless they were specifically passed partition labels as opposed to /dev/sdXX or UUIDs. Effectively I'm trying to do something which is further than my competency, but if it was properly documented there wouldn't be an issue. I've been around long enough to know that almost any system has a dozen or half dozen undocumented bugs that the community is aware of, but the assholes never bother to mention it unless directly asked, and sometimes not even then.
>>1520 both grub efi and grub legacy setup are very different to each other. Make sure you don't mix up between these two setup.
>>1521 I'm using EFI exclusively, and it looks like the syslinux install uses some weird cut-down version of grub anyway, but it just didn't have the modules. I've got it sorted out now, but it was a pain figuring out which kernel parameters to pass. Things really aren't fully documented, lots of switches and kernel options that are never mentioned at GNU or anywhere else.
>>1481 I'm not sure if anyone has a bluetooth sniffer but it's probably as simple as directly targeting the MAC address. >hcitool - This utility can be used for command-line scanning and obtaining the ever-important MAC address when connecting with other tools. >gatttool - Included with the Bluez library, this is a great tool for honing in on specific values of a General Attribute, or GATT characteristic as defined in the Bluetooth specification. >ubertooth-btle - Included with the Ubertooth software; out of all of the Bluetooth tools, this one will be used quite a lot. While hopping and chasing through the Bluetooth spectrum, you’ll occasionally get a complete chunk of Bluetooth traffic while sniffing with this utility. Don’t let the BTLE part of this fool you - all pairing takes place in Bluetooth 4.x in the low energy realm, so if nothing else, this is a great way to get a sniffer trace of the pairing process. Just be prepared for multiple tries and some patience, and when completed, you will have a nice pcap-formatted output file to analyze.

Move all your work to gitlab like you should've ages ago OP. The biggest issue with all this is that Github has become a kind of faceberg for programmers so it is unlikely that most people will drop the platform. Oh, and most devs don't even care about these types of issues in the first place, I often forget we are a minority of a minority.
>>1243 >require you to dox yourself Wrong You can make an account without any identity, like it's always been. For using the rest of the features you only need to confirm an email address, like it's always been. And for logging in to an account from another computer you only need to confirm an email, like it's always been. If you were dumb enough to add a phone number that's on you. You and OP are either trolling faggots or niggerlicious faggots. Of course MS is datamining the fuck out of shithub, but they don't care if you've given them your real name and credit card details. They want to know with whom you collaborate, what languages/libraries you use, how popular your repos are etc etc to find out if you're a good hire for and emlpoyer in you're neigborhood!©. It's nice for them to have some link between your shithub and linkedin like your real name so they can put you in contact over there, but they can just as easily add personalized ads on gitbutt.
