The article does not make it clear that the satellite signals in question are those of ARINC's ACARS data system, developed in 1978.

Probably because ACARS was turned off hours earlier in the flight, back before the aircraft flew back over Malaysia! Had it been active, ACARS would have reported the aircraft's location, altitude, speed and other useful data, making finding it much easier; it was switched off with the other cockpit systems, though, leaving just the Inmarsat terminal's hourly "ping" active, so until the Doppler analysis, all they knew was the distance between the satellite and aircraft.

I come at this from a completely different viewpoint, having only recently dipped my toes into Linux - for me, a package manager is a relatively new concept. The nearest I've come to it previously has been with Apple's App Store, both for iOS and now OSX - plenty of choice, sometimes too much choice.

As far as manually installing apps goes, it usually boils down to double-clicking on the DMG file to mount it, then either running the installation package or dragging the app file to your Applications folder.

In theory, uninstalling apps is as simple as dragging the app file to the Trash. I say 'in theory' because apps do leave behind some detritus formed by using them - thankfully not to the same degree as Windows, but it is there. For suites of apps like Microsoft Office or Adobe Creative Cloud, there tends to be a lot more extra stuff deposited onto your system besides the apps themselves.

Sadly, updates do tend to be on a per-app basis, with the exception of those acquired through the App Store, which handles the update process.

I understand wanting to regulate full-sized military-style drones, but going after small commercial entities flying go-pro carrying quad-copters is a bit much.

Just so you know, the AC may also be a woman. And actually probably is. Either that or a man who's never seen any news articles or blogs by "feminists".

First, the essentials for me, on my iMac (many of which moved with my from PC background) :

Google Chrome - go-to web browser. (Safari just doesn't cut it, Firefox is good but doesn't work quite the way I'd like it to.)
VLC - the media player that will play anything!
F.lux - mentioned elsewhere in comments, this adjusts monitor brightness from daytime to nighttime.
Pathfinder - excellent power-user file manager for OSX.
DaisyDisk - find where all that hard disk space has gone.
CleanMyMac 2 - scrub the detritus from OSX and apps.
Torrent - for my torrenting needs. :)
Parallels Desktop - for when I need to run Windows software.
Mozilla Thunderbird - my mail manager of choice.
FontExplorer X Pro - organise and manage font library, root out dupes and duds.
Last.fm - because here in the UK at least, I can still listen to full tracks. Still the best way to find where to buy particular tracks.
Spotify - I still love my MP3s, but this way I can legally share the love.
Sophos Anti-Virus - because I know better than to believe the hype about Macs being less at risk.
LastPass / XMarks - recent addition, no more hassle losing passwords or bookmarks between browsers.
DesktopServer - for Wordpress site development and deployment.
Toast Titanium - still need to burn the occasional disc.
Steam - need I say more?
Pocket - where my read-later stuff goes.
Alfred - Like Spotlight, but with brains.

There are a few Windows apps that I miss, because there isn't a good Mac equivalent :

TeraCopy - Pathfinder does bulk copy operations, but doesn't support CRC checking / diff.
Everything - Spotlight is good, most of the time, but not fast. Alfred is better, but still no speed demon.

I used to use Beyond Compare for work purposes back when I was involved in USB flash device duplication - great for checking master copies prior to duplication, and double-checking selected duplicate sticks during duplication.

Along those lines, I'd also recommend TeraCopy - fast file copying with the option of CRC checking to spot any corrupted or missing files.
