This, for myself, shows the great migration experiment has ended. I view my participation on Endchan largely though the lens of the Infinity Next failure, and the attempts find a better solution. In time, Endchan suffered its own catastrophes along with more in 8chan-land.

While Endchan remains active, it appears we've reached an over saturation of
traditional legacy boards across the whole of the internet. Still, had a few good threads here for the time I spent.

Maybe Adolph'll pick her up and plop her down somewhere in alt-naziland? Could be fun.

Good good luck BO, and thanks for the show.

Too bad that the users of this board were never that good with technology. They were years above typical people, but far from a unified knowledge base seen in only a few individuals across the planet...

Intel/AMD CPUs were hit with Meltdown and Spectre, and Intel already had the Management Engine inside of it.
Some things with TOR and other projects happened, a coordinated attack on multiple imageboards (Be lucky that I am telling you this, it was largely undetected) that resulted in lainchan, mewch, and other getting hit hard.

Activate the most CPU transistors with the least amount of Instructions?
This means Memory Controller(Read/Write), Integrated GPU, Multicore(SIMD?), Peripheral(USB/PCI/Etc.) controllers(What was once the North/South Bridges...), Intel ME/AMD PSP?, L1/2/3 Caches (Some Reverse Engineering Here...), Branch Predictors/Out-Of-Order(Deeper... Programs that would benefit from such technologies?(If/Else?...)), CPUID ROM, Microcode Memory?, Floating-Point(Double/Highest Precision)+Integer Units, Instruction Decoding(Complexity=Better?), Registers(MOVing?), Herp Derp Intel "Technologies"(AMT, vPro, Hyperthreading, VTd, Etc...) and other parts of the CPU...

Determine what instructions result in the greatest total activation?

You could write a simple C program like "main(){while(1)} to hang the CPU, but we want to push it as greatly as possible!

Your an idiot if you think this was a way for me to boast my knowledge. I would have gone on plebbit if I wanted to do that. What I am achieving here is the greatest amount of current flowing through my CPU with the least amount of instructions, to break it down at the "normal" frequencies set by the manufacturer, finding silicon imperfections if you will, might even find some unintended behavior!

Author rescinds GPL licensed code from "Geek Feminists" Anonymous 01/11/2019 (Fri) 01:21:48 [Preview] No. 13089 [Reply] [Last 50 Posts]

Reportedly, the author of the GPL licensed text-mode casino game "GPC-Slots 2" has rescinded the license from the "Geek feminist" collective.

The original author, after years of silence, notes that the "Geek Feminist" changed[1] a bunch of if-then statements which were preceded by a loop waiting for string input to a switch statement. The author reportedly noted that to use a switch statement in such an instance is no more preformant than the if-thens. Switch statements should be used where the input to the switch statement is numerical, and of a successive nature, for most efficient use of the jump table that is generated from said code.

The author reportedly was offended, after quiet observation of the group, that the "Geek Feminists" mocked his code, mocked his existence as a male, and never did any work on the code afterwards and never updated to include new slot machines added to the original code by author subsequently.

The author notes that he neither sought nor received any compensation for the granted license, that is was a gratuitous license, and that there never was any refutation of his default right to rescind given. (A right founded in the property law of licenses.)

The copyright owner has reportedly watched quietly as each year the "Geek Feminists" published a recount of their heroic efforts regarding his code.[2][3] Presumably he has now had enough of it all...

The author notes that the SF Conservancy attempts to construe a particular clause in the GPL version 2 license text as a "no revocation by grantor clause", however that clause states that if a licensee suffers and automatic-revocation by operation of the license, that licensees down stream from him do not suffer the same fate. The author of "GPC-Slots 2" reportedly notes that said clause does only what it claims to do: clarifies that a downstream licensee, through no fault of his own, is not penalized by the automatic revocation suffered by a licensee he gained a "sub-license" from (for lack of a better term.)

The author reportedly notes that version 3 of the GPL did not exist when he published the code, additionally the author notes that even if there was a clause not to revoke, he was paid no consideration for such a forbearance of a legal right of his and thus said clause is not operative against him, the grantor, should it exist at all.

(Editor's note: GPL version 3 contains an explicit "no-revocation-by-grantor" clause, in addition to a term-of-years that the license is granted for. Both absent in version 2 of the GPL)

> > Re: DMCA takedown notice

> > Date Mar 15, 2019

I am going to sue your staff for contributory copyright infringement in their personal capacity, in addition to you company.
I have given you ample notice to remove the work.

> Moreover, you have not addressed other doctrines, such as reliance or promissory estoppel, which would prevent revocation even in the absence of valuable consideration.

These are equitable defenses. Not defenses-at-law. They are determined on a case by case basis. Promissory estoppel is most often "awarded" when a defendant has, on the reliance of explicit promises to him by the owner, laid out monies to purchase improvements for the affected property.

An example is when one builds extra buildings on a piece of land one was promised ownership on upon the owners death. It is much related to the old Livery of Seisin which was used in the conveyance of land and is, in fact, a modern substitute for it.

There is little relevance between such and a licensee, one of many, who, for no outlay, had permission to use a piece of software. Permission which was later revoked.

Sometimes overwhelming clarity and conviction about things and the ability to focus sharper and longer than most is an asset that I wouldn't give up for anything. Sometimes nobody cares and I can't make them care no matter what I say or do and that same conviction is a curse because it ultimately wastes my time and damages opportunities and my relationships with others.

Seems you've missed the forest for the trees.
The point has been to edify the linux kernel programs regarding their right under US law to rescind.

GitHub disobeying the DMCA request or claiming "we don't know that you are you" is largely immaterial to this.

While you may have lost the plot, I have not. I know that this github DMCA issue is very much a side issue.

A linux kernel gratis contributor can simply file suit and not even use the DMCA.

What is illuminating is that, thus far, none of the opponents have been able to dispose of the central matter: that a license, without an attached interest (read: $ ) is revocable.

Something new from redhat:

<Marxism, Makes me think of this:

>Should your effort succeed then it is a problem with the law and not with the license.

The law is wrong because it doesn't commit a taking regarding things that were not transfered is what this marxist is saying.

> A license that grants certain rights to a copy of a work provided that certain conditions outlined in the license are met should never be revocable from THAT particular copy of the work,
unless the terms of the license itself are broken.

That is so: if you paid for those terms. If you paid nothing you get nothing. The linux kernel contributors did not GIVE anything away, they allowed USE of a thing THEY own. If they wanted to GIVE their property away they could have done so by _TRANSFERING_ it to a non profit such as the FSF, or declaring it the domain of the public. They chose to do neither.

>Having the possibility to arbitrarily revoke rights granted by a license for any other reason than conditions that the licensee was aware of when they accepted the license

There was no acceptance required. YOU are not allowed to use the owners property WITHOUT his permission, YOU do not have the right to "accept or reject" his dictats regarding his PROPERTY. You must OBEY the owner's demands regarding HIS property. There is no contract, terms, negotiation here.

The case is the easiest and cheapest part of the DIY Laptop. There are many good options, from 3D printed, plywood, acrylic, CNC aluminum, fiberglass, a briefcase, even clay, paper mache or lego. The cost will be <$20, no matter what.

The lego case is most DIY, modular and open source. It is only option that can be freely disassembled and reused. The mechanical properties of the lego are same as 3D printed ABS or ABS injection molded cases. The reproducibility of lego cases is high. If more strength is needed, the lego can be glued.

Plywood or acrylic are strong and cheap case materials. They can be lasercut.

Aluminum is an ideal case material, because it is strong, durable and light. It needs machining. Titanium is better than aluminum, but more in cost.

3D printed PLA or ABS plastic will make a case that is not as strong as plywood or aluminum, but can be made using only a 3D printer.

Fiberglass or carbon fiber is a high performance case material. It will make a very light case. Construction is slightly more difficult than the other options, as reproducibility is less.

A briefcase or binder can be made into a laptop case.

Clay and paper mache are the most DIY options.

I don't use SystemDick. OpenRC is fast enough and RunIT is even faster than SystemD. In reality, SystemD is more complicated and harder to configure (if it doesn't work out-of-box) than OpenRC/RunIT/SysVInit/BSD Init. There is something off with the push for SystemD. Just think about it. There isn't even one terminal emulator or file manager that everyone has agreed to use, but how come everyone loves (((SystemD)))?

I only used systemd for a very short time, when I installed Armbian on a board I got to move away from the x86 disaster. Well it was less than a month later before a systemd bug was causing problems (some daemons wouldn't start). Armbian didn't address the bug and simply waited for their upstream (Ubuntu) to take care of it. Apparently those guys didn't care about fixing it quickly because allegedly it only affected ARM systems. So I immediately installed Devuan, and that was the end of all that. I never even looked back to see if they finally fixed the bug.
Anyway my other computers were all running OpenBSD, long before systemd even existed. I would have used it here except they don't have good 32-bit ARM support. NetBSD runs okay, but video has no acceleration whatsoever, so Firefox is laggy to the point of 1-2 second delays between hitting arrow key or clicking mouse and it actually doing the action. Which is strange because I also tried some emulators (NES and Amiga) that work pretty damn good with the exact same Xorg driver.

I'm not using systemd and don't intend to, if an opportunity continues to exists to do so. This whole ordeal just demonstrates how much sway Redhat has over the direction of Linux/GNU distros. It can do this because of the development projects it controls.

The ultimate goal is to unify most of the userland amongst the different distributions to the point where there won't be much difference between them and then let redundant distros burn out and have those developers roll into other projects.

There may still be a few holdouts that don't use it, but as long as Redhat and Debian/Ubuntu use it, that will eventually push out non-conformists by creating an ever increasing workload in-order to un-systemd projects that establish hard dependencies to it.

At that point, the remaining non-systemd crowd may make the jump to a different UNIXy OS or just learn to love Lennart's systemd.

If you look at the big picture, this may actually not be a bad thing because it will position Linux for the "not Windows" crowd, where as folks who actually like traditional Unix, will jump over to one of the other options.

Without emails, it takes all of 3 seconds to sign up, and you never have to think about it again. I'm not sure what the issue is.
Do I then know who posts what? Yes, but broadly-speaking that's generally true for imageboards already, and it neatly sidesteps the issues that arise where you have a group of people who know their way around a VPN but have software that largely revolves around handing out bans via IP addresses. This way there are no wrong bans (unless you somehow get your credentials stolen and someone posts on your account, which shouldn't happen since your username won't be displayed anywhere) and everyone who wants to use a VPN can do so without their usage putting the site's well-being at risk.

It also opens up the possibility of users who have been around for a while getting things like a spot in a moderator election, which is something I don't think I've talked about here, but have at length on /g/.
