From a brief glance, Plex appears to be for streaming existing content. MediaGoblin is for hosting content you create.

Were I seeking a wider audience, I'd have the options of Vimeo or Xtube or Soundcloud or Bandcamp or Flickr to put my content online.

And if you don't want to turn your own content over to third parties, and thereby be subject to their licenses, and often arbitrary censorship/takedown decisions, you could use an instance of MediaGoblin to replace any or all of those services.

What's stopping me from using the dozens of web content galleries

Nothing, but if you're going to do that, you might choose to use MediaGoblin.

While I agree that NC is generally misunderstood by lay licensors, and greatly more restrictive than most people realise, ND has a valuable place in the licensing suite.
For example, if you write an opinion piece, adding the ND clause will make sure that no-one can (legitimately) alter or distort the text, and use it to misrepresent the position you hold/held.

Otherwise, using ND for non-opinion works shows a certain amount of arrogance. It's effectively proclaiming "no one but myself could possibly make this any better".

You don't have to have the source to modify it, it just makes it dramatically easier.

"We're not stopping blacks from voting! They just have to fight their way past the KKK barricade around the polling station."

Moore's law doesn't suffer under the current regime, because Moore's law was written within the current regime. There's no telling what would happen, or what would have happened, in the microelectronics industry without the current patent rules. Perhaps Moore's law would have been "...doubles every 6 months", instead of 18 or 24 months?

What products covered by "dozens if not hundreds of patents belonging to dozens or more different companies" do is encourage collusion and anti-competitive practices, and even in the absence of abuse massively raise the bar for new entrants to the market (aka competition).

Does your country have laws protecting corporate whistle-blowers?
It's a lot easier to defend your position if it's the FBI asking you to make surreptitious copies of documents, after they called you following an "anonymous" tip-off...

Well, sir, there's nothing on earth like a genuine, bona fide, electrified, one-car, SkyTran!

What'd I say?

SkyTran!

What's it called?

SkyTran!

He's famous enough to have a Wikipedia page, which IME is a reasonably high bar for someone who isn't an anime character.

What part of "Pay for the service your ilk required us to set up or get out is evil?

I think it's more along the lines of: "Pay for a membership to our Legitimate Businessman's Social Club, or we'll run you out of town."

Because:
1. It's not initially feature-compatible with OpenSSL
2. While there is momentum, it's faster to work apart from the existing project.
3. There's no guarantee the rewrite would be accepted by the OpenSSL team
4. There's no guarantee LibreSSL will work on anything but BSD
5. Theo doesn't control OpenSSL

Personally, my hopes are:
1. This Linux Foundation fund identify LibreSSL as the most feasible solution in the long-term, and provide support for both projects.
2. Important bugs identified by both teams are ported to patch the current OpenSSL release.
3. LibreSSL gains feature parity with OpenSSL.
4. LibreSSL becomes OpenSSL v2, under the stewardship of a healthier OpenSSL community.

The information in those demonstrations is trivial and hardly helpful once put to the test. People will panic and that means that little boring sermon will mean almost nothing where it counts.(as always happens)

Perhaps we should be campaigning for people to undergo aircraft-emergency simulations?
You're right that people panic, but people only panic because the situation is unusual. If people regularly experience "emergency" situations without the danger/fear (especially throughout childhood), they can be trained in what to do enough that handling a real emergency becomes routine and practically instinctual.

So what do you do about colleagues in other time-zones? Or on other shifts? Are they not allowed to email you outside of the times you're both at work - assuming there is any overlap at all?

Email is not IM; it's not designed to require or expect an immediate response. Nothing about sending an email necessitates that it must be acted upon immediately.

For storing and querying arbitrarily-structured data, which is what the submitter seems to be wanting, a traditional relational SQL database is not necessarily the best way to do it.

And if anything, MongoDB is easier to start using than any relational database, IME. No need to create databases, schemas, or tables (collections) beforehand - you just install MongoDB, start writing data, and it gets stored.

MongoDB has indexes.
MongoDB also lets you store and query arbitrary data, in addition to any "key fields", without having to pre-define all the possible fields. Which it seems is what the submitter asked for.

Where has this idea that "NoSQL" means "not a database" come from?

Short version: They have a perfectly working computer with all their stuff on it. Why should they have to throw it in the trash and go through all the pain/expense of an "upgrade"?

Not to mention that, for many people, Windows XP is the only desktop operating system they've ever known.
XP has been around for 13 years. In consumer technology, that's an incredible length of time. After so many years of consistency, of course there are going to be people - millions of them - who don't want to face change.

I like Redmine, I do, but it has no support for actually being a source control server. On its own, browsing local repositories is all you get.
