Don't worry, fiver, you aren't.

Yes, Yahoo still has an email thing. I know exactly one person who still uses it. And pays for it.

When reading the summary, I was sure that this:

gently lambasting staff who refuse to part with Microsoft Outlook

... was going to read "gently lambasting staff who refuse to part with Gmail" and Yahoo was imploring their employees to switch to Yahoo! mail. As bad as Yahoo's mail system is, Outlook is worse. I figure 75% of Yahoo is sales people.

No, they are saying that you can always find a pair of primes separated by 600. Let's say you list all the primers between 2 and N. You enumerate all the pairs whose difference is 600. What they are saying is that if you look beyond N, you will always find another such pair. They are NOT saying how much further you have to look.

They are *not* saying that given any prime number p, then p+600 is also prime.

Their goal is to demonstrate that the same is true for 2 instead of 600.

You have the hubris to say that you are going to fix everything that is wrong with X11 / X.org AND also provide a compatibility layer on top of your new shiny solution to support running the programs that still use the thing you are claiming to fix ... and now you are surprised because getting said compatibility layer right turned out to be thornier than you had expected?

Several years ago I wrote a transport mechanism on top of VNC that allowed you to access high end graphics services (read OpenGL) from devices without any hardware acceleration to speak of (back then it was an ipaq). I did the initial implementation in one evening, which worked for 80% of the use cases. Together with another developer, it took us probably a month to get it to 90%. A third party worked for half a year to get it to 95%. Several years later it was up to 98%... maybe.

Whenever you try to pull this kind of stunt off, you are going to run into the same situation. Most of the stuff that you are interested in is easy. Then there's the stuff that makes "creative" uses of existing APIs. And then there's the stuff that works because of, not despite of, existing implementation bugs. And then you run into the really weird...
