Colorlib membership still works or it's scam?

Someone recently bought an annual/lifetime subscription from them this year, share the experience here if it worked, because I can't get in touch with them anywhere.
Well, I bought a lifetime all template license last year in october. When I bought it, there were no account creation, and the website stated "it's a lifetime access for $99"
But recently, they changed their policy and now people who paid the $99 all template don't have access to templates anymore. On the support forum they ask you to log into your account (and of course you don't have one since there were no account creation when buying the licence), then they tell you to create an account with the same email you bought the licence. But when you follow those steps and check your new account, you can see "no purchase history" in teh dashboard.

I am trying to explore services of google compute engine,is there any free tier eligibility for exploring purpose. Like aws does provide free tier for new account holders for 1 year?
Yes, You are given 300$ credit for 90 days, after that there is an always free tier.
Use their price calculator to get an estimate
Google provides Starter Pack, $500 credit package for new coming developers on Google Cloud Platform, $500 is more than 1 year free tier server on other platform.
https://cloud.google.com/developers/starterpack/
Just apply it and watch that space :)
update: Feb 2022
Yes, apart from 300$ credit for 90 days, there is an always free tier, that includes an App Engine, Compute Engine etc, more about free resources.
use their price calculator to get a cost estimate
Simple answer is YES
But it's not a 1 year trial like AWS.. it's a credit of $300 which expires in 60 days, after which you need to pay for continued usage.
Yes there is. It was recently introduced, and Google Cloud Platform offers a free trial worth $300 to all new users. As soon as you sign up, you immediately have $300 to use on any Cloud Platform service - including Compute Engine (as well as App Engine, Cloud Storage, or whatever else you want).
Check it out on cloud.google.com.
Yes, it is the 'Always Free' tier (almost identical to the Free Tier of AWS):
The Google Cloud Platform Free Tier is your opportunity to learn and
use GCP for free. It has two parts: a 12-month, $300 credit free trial
and Always Free. The 12-month, $300 free trial allows you to use any
GCP product. Always Free allows you to try participating products for
free up to their non-expiring usage limits, making it easy for you to
test and develop with these products.
In essence, it is completely separate to the free trial offered ($300 for 12 months) and is designed for developers to explore and develop applications and services that use the services included in Free Tier, without being charged (also note that a SLA does not exist with Always Free).
Usage of the Always Free tier does not use any free trial credit you may have:
You are eligible for Always Free usage amounts during the free trial period. Always Free usage does not count against your free trial credits:
For example, only the portion of your Google App Engine usage above
the App Engine free daily usage limits is charged against your $300
credit. In addition, if your App Engine usage is below the free daily
usage limits, your app will continue to run even after the free trial
ends.

Who pays developers of open-source software? [closed]

We are facing a lot of open source software.
But someone needs to write that software. How are they payed?
Do you know a good article about the open source politics and economy?
Sometimes the big companies themselves release open source because they have some benefits.
Then they sell support, advices ...
My question is what is the real economy about open software?
No professional will work for nothing. This software are couple of classes but thousand or may be millions of classes. If you are really a pro you will write software for money, because you have life, wife, kids, taxes, you must earn.
Please do not tell me that they are doing this for pleasure or hobby!
On Stack Overflow, we get a lot of good quality answers (and questions).
But somebody needs to write the answers. How are they paid? Surely no professional would spend time hanging out here and answering questions for nothing.
...
This, of course, is not how it works: people get pleasure from contributing to something, from testing and extending their knowledge, from being part of a community. Thus they write for SO in their spare time, and enjoy doing so.
Free software is no different.
Eric S. Raymond wrote The Cathedral and the Bazaar and other essays about this, and these are probably the best place to start. There's also a Joel on Software essay somewhere with some good points.
Some people write free/open source software because it's something they personally want. Some do it as part of a reputation game, similar to academia. Some people get paid for it.
Companies pay for it because they make money off it somehow. O'Reilly Books makes money by selling books on using free software. Red Hat makes money by providing enterprise-quality support. Apple makes money by adapting it to their needs and selling computers using it. I think IBM is working on Linux so they can slowly move away from AIX. Some companies find it more economical to develop free software in conjunction with other companies, so everybody can use it and nobody has to pay too much.
Companies that make their money selling software, like Microsoft, will generally avoid free software. Companies that make their money on something related to software will want the software as cheap as possible, preferably free. In some cases, this means software the customers use, and in some cases this means software for internal use.
Most of what I've done on FOSS projects has been unpaid, either building a tool or some functionality that I need at the time - "scratching my own itch", as ESR puts it. This doesn't mean that it doesn't make me money. As a freelancer, the tool I build/improve today could help me land a project tomorrow or help me get an existing project done more quickly, either of which is good for my bank account.
Back when I was working as someone else's employee, there were also times when I developed code on the clock that would help with my job, or other employees' jobs, but my employer wasn't in the business of selling software anyhow, so they were willing to let me release it under a FOSS license.
Today, I offer clients a discount on work done for them which will be released under a FOSS license, in which case I would be getting paid directly for work on FOSS code. Nobody's actually taken me up on it yet, but a current client has asked whether certain parts of their project would be suitable for open sourcing, so they're clearly open to such arrangements and looking for an opportunity to get that discount.
Edited to add: Freelancing has not been kind to me in the six months since I originally posted this answer (too hard to find paying clients for my language of choice), so I have accepted a full-time job with the local university's library, where I will be helping to clean up their in-house collection management application so that it can be released under a FOSS license sometime next year.
So, yes, there are jobs out there where writing FOSS is the primary job responsibility. I suspect that they're mostly in the public sector or at educational institutions, but there are also some private corporations (like, say, Red Hat) where such jobs can be found.
When you say "professional", by definition you are establishing the value and compensation context of your question/statement. But software is not just created as an outcome of the fruits of a profession. Software is art. Some writers have to write, some painters have to paint. Coders need to code. We all acknowledge that it would be nice to be paid for doing what we are. Some are better at it than others is all.
Look at Linux, MySql and many others. There are huge corporations behind the most successful projects, so people will work there as they'd do for any other employer.
A detailed discussion here: http://news.slashdot.org/story/10/04/27/0048250/Why-Making-Money-From-Free-Software-Matters
Most open source software work is done completely unpaid.
Some open source software is useful enough that a company that would benefit from the software being better will "donate" developers to work on it. For example, RedHat - who markets a paid version of linux - may pay for developers to improve certain parts of GNU Linux.
Some open source software has paid support, or paid consultants. So, MySQL was free, but also offered professional consulting based around the software they were already experts on.
But most open source work? Unpaid. Normally, it's a great thing to put on a resume to get you a paying gig.
I am currently working on several open source (GPL) projects. Pay comes from various government grants via the local university.
I found a good article: The simple econimics of open source by Josh Lerner:
My guess:
60% of open source development is
done by developers payed by
corporations
20% is done by developers which like to learn and improve (also having in mind their day jobs)
10% is done by students to learn, or as assigned works for university projects
5% is done for a better world (open source corporations like Firefox)
5% is done for games and fun
Usually nobody unless you work for Mozilla, Google, Yahoo, etc.

what public service project would you create

if you had
4 software developers
any open source software
server hardware
internet connection for hosting
100 person days in which to do it?
How about a site equivalent to Rent-a-Coder but for non-profits to solicit volunteer or low-cost developers for public service projects (i.e. make your question easy for the next guy in an equivalent situation). Given the current economic troubles, there are likely to be both a lot of unemployed developers and a lot of troubled non-profits (and a lot of demand for the various kinds of help those non-profits provide). Let's put them together.
Add a point system like StackOverflow so you can earn points by helping out non-profits with their web applications or whatever. Then go get some corporate sponsorship so that you can turn your points into credits at Amazon.com or some such.
