My IPTV traffic

I have IPTV from Elion.

Here are it's statistics:

Quite impressive traffic, almost-almost 1TB.
The funny thing is, that it's based on multicast, so the upstream is so small (40MB).

Total length of videos on the internet

Recently I became very curious about how much video material there are publicly available on the internet.

So, I took few numbers out of Google Video search.
After adding up all those minutes, it became obvious that I may not live long enough to watch all of them :P
In fact, it will take much-much longer...

So here are calculations:

113000000 * 3.59 minutes = 771.310869 years
75300000 * 4 minutes = 572.679355 years
9990000 * 21 minutes = 398.879156 years

771.310869 years + 572.679355 years + 398.879156 years = 1742.86938 years

So the final answer is that there are currently at least 1742 years of video available to watch.
And that's always counting.

BTW, if we're talking about increasing numbers, Gmail is 7074 MB now.

New 1-Wire sensors

Posted by Picasa

Bunch of SMD and non-SMD 1-Wire temperature sensors - soldered and ready for install.

Only I don't know where to put them and when I'll do it.
I need to pull new cables and also think about how I surge protect them from possible lightning or switching transients.

Of course, when it fries, then it fries, but for a little bit smaller events, it's good to have something.
