>Reading anything by Zed Shaw
Grab yourself a copy of Automate the Boring Stuff by Al Sweigart and/or an actual CompSci textbook. Just the former is fine if you're not thinking about programming for a living, you'll find your way to a CS textbook eventually. The things Al goes over are pretty real-world and will generally help you in one way or another.

Zed Shaw is an incredible moron who has no business trying to sell himself as a teacher. You'll get to a part in his book where he starts talking about things called classes and objects. The way he describes them and demonstrates them is completely ineffective and an actual CS textbook will have a much clearer explanation.

Notice that the only thing he has you do is utilize print statements to "see" your results. Any other book will give you some kind of actual exercise to utilize what you've learned; Al's book is kind of special in that if you follow along, you'll have some basic tools and general understanding of them, but you'll need to do something on your own to reinforce it. That's generally why whenever someone asks about learning python, I'll tell them to pick up Automate the Boring Stuff AND an actual CS textbook because you need questions to answer if you don't have any pressing problems to solve.

This echoes my thoughts.
Also I would be forced to force others who wish to use my work to pay it forward also, even if I don't wish to impose that on them. Now I am the tyrant, against my will.

>I guess I thought every school had a Linux server for the students.
This doesn't mirror your previous implications at all.

Of course nearly every university has Linux boxes for testing and dev. In many cases, you will run Linux VMs on a Windows machine for doing simple testing with things like Red Hat.

However, the majority of professors, and students in any department, including CS, are going to be using Windows or macOS.

i felt this question wasn't worth a new thread.

Murdering immediately harms someone.

You would need to argue that non-GPL software actively harms someone, rather than the more reasonable stance that it is intended to help someone.

there's shit in unity / gnome 3 / kde that was taken directly from OSX. mostly GUI concepts.

X11 is open source, it may be a shitty move to use it but not contribute, but it's within the intended use of the licence. what can you do. and i feel like if anything, copying should be more common and copyright should be less stringent. it only keeps development back if everyone has to reinvent the wheel because the wheel is copyrighted

the best company/devs will always have the best product because they're actually talented devs and GUI creators who know how shit should work and look to be usable and intuitive. if you just steal stuff with no concept of what you're doing it'll end up looking like one of those gaudy apple themed ubuntu mods

Gui framework and language for Windows and Linux, easy to quickly prototype, easy sql interface for the server side, speed doesn't matter, simple to use network packages. Suggestions? Anything new for me is absolutely OK so no restrictions at all on the language.

I'm of the opinion nowadays that we should strive for a lot of inference so that we get the most general type possible. Annotations are comments that are automatically verified to match the code or in some cases ways of resolving ambiguity (such as with dependent types).

C. Provides a way to organize code into projects and makes it easy build programs(what a text editor won't do)

It's pretty ironic that stallman always points out the difference between free as in free beer and free as in freedom, implying that the GPL grants the latter, when in fact looking at the evidence GPL programs tend to be more like free beer; they have no monetary cost, but severely restrict your freedoms.

No it restricts your freedom. It basically says that no matter what, you effectively can't make any fucking money developing anything that has even skimmed a line of GPL code. And then forces you to subject others to the same if you give in. It hampers development and adoption.

What hampers adoption more is when proprietary projects die and end up being lost forever because they're closed source. I'd be fine with proprietary software as long as the license terms require the source to be placed in the public domain once they fail to sell X units a year.

So? You can't give everyone absolute freedom without infringing on other freedoms. So the FSF decides that having freedom to use software for your own purposes, but not to make a proprietary fork, is the best route.

>They arent freaking out and re-writing all the firmwares in their house. But somehow it only matters with their OS.
Because they already have the OS, so they want to prevent it from becoming proprietary. If and when they have written free firmware, they won't want it becoming proprietary either.

No, it's to allow the end user to understand and thus modify the software. That's why the LGPL allows dynamic linking to proprietary binaries - you can still theoretically replace them with your own code.

Yeah look there is that, and also the argument that basically copyright lasts too long

I also think that if you have say a GPL python module that the user has installed themselves, you should be able to write a python program that imports that module and license your program commercially, since you're not redistributing the GPL module, though the FSF disagrees.

>>59846965
Try putting "example.c" at the end.

>>59846971
I'm not Stallman though.

>>59846975
GPL ensures that all future versions of the software remain free.

>>59847005
>Fuck off faggot. It effectively prohibits you from developing commercial software, i.e. selling your work.
Developing proprietary software is restricting others' freedom. And if you think you have a right to forbid users from modifying your code, then the FSF definitely has the right to forbid their code from being used in proprietary projects.

>>59847018
>GPL ensures that all future versions of the software remain free.
But it's more "beer free" than "freedom free"

Do you want your software to be used?
MIT/BSD

Do you want your software to be used and still have any derivatives opened source?

How does the GPL prevent commercial use? Without DRM that further restricts freedoms it's just as easy to distribute proprietary software and even DRM gets foiled after some time.

Even though they still could because no one would take them to court.

While it's easy to distribute proprietary software, you can sue anyone who does and have it taken down. Any businesses who use this would be liable for commercial copyright infringement (max penalty is.. hundreds of thousand per copy? millions?)

No, beer free means you have the ability to use it for zero cost, but not necessarily to modify it. Freedom free means anyone in possession of the software can use and modify it, and distribute it in any way that keeps the software free as in freedom.

>>59847068
>No it's not. They're free not to use it. :')
In which case no one can use your software without it restricting their freedom. There is no usage of proprietary software that does not violate one's freedom.

>>59847185
If only legal fees could be payed in toewax and delusion. The world would be a much better place.

>>59847159
So? If they can do a better job then let them. Otherwise the software is worse off just so that someone else can make more money.

>>59847177
Good point, but when it comes to enterprise then the fees are more for support than the software itself and you can't pirate support.

>>59847209
>Freedom free means anyone in possession of the software can use and modify it, and distribute it in any way that keeps the software free as in freedom.
Except all GPL code is actually free as in free beer, because it restricts your ability to sell it

>>59847246
No you can sell GPL code. You just can't close the source.

>>59847246
No. Anyone can sell GPL'd code for any price they want. The only real requirement is that the new owner must receive human-readable source code, and they too are obligated to follow the terms of the GPL license.

>>59847258
Name me one (1) GPL program you can't get for free that has been sold.

> Freedom free means anyone in possession of the software can use and modify it, and distribute it in any way that keeps the software free as in freedom.
But GPL forbids me from distributing it on trurly free licenses (i.e. MIT or Apache), so it's not freedom free

effectively killing your revenue since anyone after the first person can come, release the source or even distribute binaries without you needed.

There is a reason why LGPL was made, no one wants to put up with GPL when you want to make a living off your software.

>>59847284
>Name one (1) proprietary program you can't get for free that has been sold.
Legally, none of them.. And the source? Pretty much all the big ones.

It took Apple like six years to finally implement a slide up quick bar, banner alerts and all kinds of other things the JB community did. Id rather depend on the autism of the internet.

>>59847299

No problem, if the OSS community can do a better job maintaining and supporting it than Apple then people will not pay Apple for it.

>>59847309
>purchasing things with tiny green rectangles of paper
When are people going to realize that money itself has no value?

Redhat is arguably the biggest revenue maker when it comes ot GPL and it's because they have to sell themselves as a support group/service. That's what you become when you use GPL code.

>>59847258
>No you can sell GPL code. You just can't close the source.
Why would anyone buy something they can get for free?
Sure the GPL doesn't explicitly say "You can't sell this" but it may as well say "Hope that first sale covers the costs of development because you won't find a second buyer"

>>59847348

>Worker Practicies in Communist Societies
>Historically, Communism has been found to not foster good work ethics. Michael Lindsay explains, “The actual Communist choice is almost certainly that “Socialism” defined in Communist terms, is a more important objective that productivity or raising the standard of living.” Hence, in all transitional societies working toward Communism, work ethic and motivation appear to be extremely lacking even though everyone is assigned some task or job. For example, in a study conducted in the former USSR, over 50% of the work force admitted to drinking alcohol while on the job. Furthermore, unbeknownst to the communist party, nearly 40% chose to work a second job privately to attain more wealth (Pereira) .

It's almost like people don't really think working harder for the same reward is a good idea.

>>59847616
>>one entity profits while the rest slave away

>>59847581
>t. unlearned individual

>>59847653
>In some instances, the reinstatement of some private property was needed to provide incentive for workers to produce useful programs and inventions. In one analysis by Tao-Tai Hsia and Kathryn Haun, they found that the Soviet Union had “to offer the inventor the choice between a patent, which conferred the right to exclude others from the use of the invention, and a certificate of authorship, which vested ownership of the invention in the state, but entitle the inventor to various privileges and to remuneration based upon the economic benefits realized by the state through use of the invention.” However, the very introduction of acknowledgement and reward contradicts the belief the notion of the unselfish worker.
Kek, even the commies had to pay people to write good software.

Well it's weird because all the people and governments who have ever called themselves communist disagree:
>Within a communist society, people are expected to act in the interest of the Communist Party and the majority of society. Specifically, the individual is expected to work and act to promote the betterment of the community. Chairman Mao Zedong elaborates, “At no time and in no circumstances should a Communist place his personal interests first; he should subordinate to the interests of the nation and the masses. Hence selfishness, slacking, corruption, seeking the limelight are most contemptible, while ... working with all one’s energy, whole hearted devotion to public duty, and quiet hard work will command respect.” Hence, communists are expected to work diligently and thoughtfully in order to ensure he or she provides the most benefit to society. As a result, any worker in the computer field is expected to manufacture computer products without the wish for acknowledgment or excessive monetary reward.

I'm very familiar with C, so basic things like for loops and pointers won't be an issue. I'm also very familiar with Java, so the OOP side of it probably won't be too hard to pick up.
