You do understand there's no license to shitpost in The End℠ right?

There is no true objective winner in the license wars, every public or private license has its own purpose. Having Stallman or Terry won't change how people will always be triggered. If anything, people like you want to take over this board.

Provide me a competent image and have someone else here to agree with you in its implementation and do it ASAP but don't make me wait too long. However, this is really truly a non issue, but the real issue is that I will only allow just one more sticky image change. Get it right this time or I'll remind you all it's your guys' fault and I'll make a new sticky without any OP image and make it an official rule to not bitch about the sticky thread image posthumorously when there's no sticky image to even complain about.

Again, grow up, and if you think Terryposting is spam, report it.

Very good news. Let's see the performance impact. As undeadly contributor said, help test the snapshots from 22 february. Here (check the SHA256, please - use install62.fs for usb stick or install62.iso for CD-ROM):

FLOSS and licensing Anonymous 07/31/2017 (Mon) 16:22:43 [Preview] No. 10510 [Reply] [Last 50 Posts]
Hello /tech/,

I'm not so familiar with software licenses so I started reading about the subject. At one point the question 'How does one profit from floss software?' popped in my head and these are some articles I came upon (quite outdated, but they still have a point). So GPL prevents companies from making proprietary software with your piece of software. BSD, on the other hand, does not (that's the case with Apple's kernel). Turns out the only way a company can profit from GPL license is by donations, offering support, teaching or dual licensing. Dual licensing seems like the most used option.

https://www.linuxjournal.com/article/5935
http://sealedabstract.com/rants/why-the-gpl-sucks/

>But there is a net effect on software development. Who makes money off GPL code? We go back to Novell and Red Hat, who test and package this software. And we see a trend–GPL code helps software testers make money. It helps QA people. It helps the people who answer the support phones. It helps everybody except software developers. Oh, maybe Google will pay them a salary as a goodwill gesture. But it’s really, really hard to make money from developing FOSS. You can make money supporting it. You can make money testing it. But no money developing it.

So my question is - does free software actually benefit the developer?

>The GPL makes it harder to make money.

That seems a little like saying that you're going to be hungrier because mom added a side of broccoli to dinner. The existence of GPL software adds to the options that you have if you are developing software and want to make money. I don't think it makes anything harder.

Perhaps the core idea there is that the GPL doesn't make it as easy to make money as a license that allows you to take someone's code and resell it as your own does. I agree with that. For example, the zlib license is easier to make money with than the GPL license because you can use it in a commercial product and not release the source. That doesn't seem like a reason for me to complain about GPL software that benefits me and sometimes does what I want in other ways though.

What's the bottom line beef here anyway? If you are opposed to GPL licensed code and, like me, don't include in your development projects when you don't want to release under GPL, then don't use it. Problem solved. I use it when it makes sense and I want to give code that keeps on giving away and I don't use it when it doesn't.

If making FLOSS software meant helping actual competent and interesting programmers and computer engineers/scientists, then I would disregard money for the most part. I don't believe individuals/groups make FLOSS software for profits in the first place, if they wanted profits, it would be more efficient to write proprietary closed-source software for large companies or massive groups of computer users.

There are plenty of benefits of being a FLOSS software developer:
>You are more likely to be recognized by FLOSS communities which tend to be populated with highly intelligent and competent individuals.
>You are helping fight proprietary, non-free, and closed-source software by distributing and creating FLOSS software.
>You can very easily use your own software to your advantage and have an extra highly strong layer of security by using your own software that wrote.
>Your software has a higher chance of being used in OS distributions and software bundles (Look at Chrome OS). If you don't like your software being used against your will, maybe it shouldn't be free and open-source in the first place.
>You are seen as a trustworthy person and will be useful in the fight against surveillance and unwanted data-collection.

It also seems to be a misconception that once can only program either FLOSS or proprietary software and not both. You can make some of your software FLOSS and other software proprietary.

You make the same mistaken assumption as everyone else.
Let me clear this up for you.
The cost to develop software is smaller than the cost of maintaining software.
Freedom software is a good way to find low/zero cost maintainers.
You're welcome.

I had similar concerns and so I did my own research on the matter. I found this one guy's 2006 blog who btfo GPL as far as I'm concerned.

http://antignu.blogspot.com/

>So my question is - does free software actually benefit the developer?
No. All of the suggested business models are pathetic and won't work long-term.

https://en.wikipedia.org/wiki/Business_models_for_open-source_software

It's as you say: you must provide support or dual license. What the FSF and OSI get wrong is that proprietary does not automatically mean closed source, and 'proprietary' is not inherently wrong. Here's a quote from Richard Stallman that shows a flaw in the design of GPL for making money.

>With free software, users don't have to pay the distribution fee in order to use the software. They can copy the program from a friend who has a copy, or with the help of a friend who has network access. Or several users can join together, split the price of one CD-ROM, then each in turn can install the software. A high CD-ROM price is not a major obstacle when the software is free.

lowRISC: another year bites the dust? Anonymous 10/18/2017 (Wed) 05:41:40 [Preview] No. 11571 [Reply] [Last 50 Posts]

I'm pretty sure the lowRISC FAQ said 2016 last year. It didn't happen, obviously, and it was changed to 2017, but we're running out of that, too. Ten weeks left, boys. Is a lowRISC SoC vaporware for another year?

At what point do we start looking to the J-x processors based on Hitachi's SuperH architecture? The last SH-4 patents are expiring this year.

>why RISC chips always run so fucking hot
ARM is RISC and run really cold. I don't think that a issue is RISC. Power was constructed primarilly for servers, so it will have more cores running, more L1 cache entries, so on.
>How is it that x86 has gotten around this?
From what I know, adaptative methods. For example, the clock and voltage adapts to the need of the user.

it's exactly for enthusiasts, unless by enthusiasts, you mean the kind of enthusiast artist that buys Crayola instead of watercolor. HiFive is offering a modern computer, on an entirely new, unexploited platform, for us to program, all for a measly grand. The opportunity here is huge, and poorfags are gonna dismiss it just cuz it's not China cheap and includes proprietary parts.

If you are not used to using Linux, I recommend starting with Ubuntu. Unless you have a very good reason, starting with a pentest-specialized OS like Kali or BackBox seems stupid - I don't see why anyone would want to use these for general purpose computing. If you are experienced with Linux or don't mind a very steep learning curve, I would recommend Arch Linux or Gentoo.

4 GB USB probably enough, some OS will require 8 GB.

Software support. Most UNIX-like systems lack support for mainstream tools that these guys need. Also, the US government has contracts with Microsoft, as well as universities.
The server running the services from police is most likely a gnu/linux or BSD system.

Some sensitive groups in inteligence agencies don't use Windows because of security, just the 'normal' police.
