I'm a desktop admin and JVM dependencies are the bane of my existence. We have to run a large number of apps supplied and/or written by our clients so we often run into "JRE hell" on the desktops. Why do so many java apps require a specific version of the JRE? Why can we not install the latest, or at least the latest 1.4/1.5/1.6 etc and be done with it? Very often the apps we run insist on the version be correct right down to the patch level.
We have java apps that:
- Require a specific JRE and fail to run without it
- Require a specific JRE and fail to run without it AND fail if any other JRE is present.
- Require a specific JRE but don't check so they fail in interesting ways. For example, one app can't copy and paste if the JRE version is off by even one patch level.
On top of all that we get lots of drive by downloads exploiting old JRE bugs and infecting our machines. We haven't had an MS caused drive by download in at least three years.
.net is way better in this regard. Install the grand total of TWO runtimes and you are done. WSUS patches them and the patches don't break anything.
HDMI 1.3 does support up to double the bandwidth of single link DVI, so it's basically equivalent to dual-link DVI. I don't know if anything supports it.
There is also a dual-link version of HDMI with a different connector. With the double bandwith it is basically equivalent to quad-DVI. Again, nothing really uses it.
There were not plenty of viruses for pre-OSX, no one cared.
I've seen virus counts of between 50,000 to 150,000 for Windows around the time OSX came out. Lets say 100,000.
Just before OSX came out MacOS had between 1 and 5% of the market. Lets guess on the low end and say 1%.
That would indicate pre-OSX should have had a "virus market share" of at least 1000. In reality it had at most 80, more likely only 40 in total.
pre-OSX had no were near the number of viruses it's market share would indicate. As pre-OSX had no security at all, security by obscurity worked pretty well for it.
While I think you got it backwards, I get your point. 3.1 -> XP was a bigger jump than XP -> 7
However:
3.1 required 2 MB, ran OK on 4
XP required 128 MB and ran OK on 256. That is 64 times what 3.1 needed over 9 years
7 requires 1 GB and runs OK on 2 GB. That is 8 times XP over 8 years
I meant "DOS with a GUI" to show how primitive an OS MacOS was on a technical level. It had no memory protection, no security, primitive memory management and poorly done cooperative multitasking. Other than the multitasking it was on the same technical level as DOS, just with a GUI instead of a command line.
Windows 3.1 ran circles around MacOS on a technical level, even if it's GUI wasn't as pretty.
You want an example of security by obscurity? Or maybe it should be security by no one cares?
MacOS
Not OSX, the OLD MacOS. It was used in the business world just like OSX is today. But it was different in one critical way: It had NO SECURITY AT ALL!
It had no security, no memory protection, nothing. By your logic it should have been overrun by viruses. Or at least have a proportional amount compared to its market-share.
Just before OSX came out in 2001 MacOS should have had between 500 to 3000 viruses if it was proportional to the windows market-share and number of viruses (depends on which numbers you use). It had 40. Forty.

7 doesn't look too bad.

No, OSX has some BSD in it.
MacOS 9 and lower have no BSD in them at all. It is basically DOS with a GUI and very crude multitasking. No security at all.
