open- Source software I'm sure a friend or at least a weird roommate has told
you about it at some point or another often with a derisive snored about the
fact that you're plunking away writing this video on the copy of Microsoft
Office that you paid for but don't just bury your head in the
expensive sand maybe there's actually something to it we'll start by
describing the opposite of open- source software proprietary or closed Source
this stuff follows the centuries old monetization model of gather or make
something that people want and then sell it to them at a given price sort of
through the use of mandatory licensing agreements that you implicitly sign when
you run it proprietary software avoids
selling you a copy of the software that after you've bought it then belongs to
you instead they'll sell you a license
to use the software that comes with a variety of restrictions including
limiting what you may or may not use it for whether you can share it whether
you're allowed to alter or reverse engineer it or even limiting the
hardware it can be installed on Apple famously gives away their OS 10
operating system updates for free as long as you meet the necessary Hardware
requirements well that sounds like rubbish I should own the things I pay
for is this how open source works sometimes actually the answer is a
little more complicated than that it depends on the licensing that word again
so we'll start with a special case that many folks confuse with open source
called called Source available this applies to software that may have been
published on a blog or otherwise entered the public domain but that the creator
has not explicitly allowed modification
or reuse without payment or even at all
open source software by contrast is
usually free software but these terms actually shouldn't be confused because
free software is strictly speaking more of a philosophy and open source is just
a development model where many collaborators contribute to a piece of
software together to make it deliver as much value to the user as it can so
let's talk advantages number one it's free to use and if like most open-
Source programs it's licensed under the GPL it can actually be studied modified
and shared as often as you want and with whomever you want as long as the
derivative Works carry the same freedoms
it's called copy left it's kind of a play on the copyright thing cool right
on top of that open- Source Advocates will point to Quick implementation of
new features and standards and the security and error-checking benefits of
having a huge Community overlooking the development but there are two sides to
every coin and detractors often point out that without the guiding hand of a
senior VP of something or other it's easy to end up with underlying code
that's as wonderful as a bacon flavored mouth guard and then a user interface on
top of that that's flat out impossible for an average user to navigate not to
mention that there's no tech support hotline reducing its usability once more
so then why do developers contribute their valuable time to this movement
well some do it out of a strong moral belief that everyone should have access
to functional and secure software others
do it just for fun or to share little projects they created in their spare
time and see what happens to them as others continue to modify them and
others have actually found ways to make money by giving the software away
whether it's by charging for support charging for optimized Hardware or
charging other companies sponsorship fees for access to their large install
base and on the subject of charging
company's sponsorship fees to access a large user base
