(well, gotta build mine first.... but it doesn't seem too hard.)
dude, those are famous last words!

This could be the beginning of...
..Livejournal TV! Imagine, not only do you sell a digital recorder, you also set up a network with content provided from the creative folks who populate livejournal.com

Re: This could be the beginning of...
Podcasting, meet MythCasting.
... pushing the Blortal revolution.
"I should run a side business"
and then sell said business so you can concentrate on making the MythTV boxes... on the side.
You could buy another Porche! I mean Audi.

You don't mention in your spec list what size HD you're going to put in there. What kind of hard drive do you need for something like this? Doesn't HD record at a rate of about a gigabyte/hour?
So does my low-ish bitrate Hardware MPEG-2 recording of normal TV...

No disk. It'll use the fileserver in the garage over the gigabit network.
But otherwise I'd put one or two of the few quiet SATA disks in there.
It takes less than 60 seconds to write a gigabyte file on my laptop harddrive. Some drives can write to the raw device at 50mb/s, which means ~20 seconds to hit a gigabyte. With proper write clustering a filesystem should be able to hit that kind of throughput as well.
i finish making a big ass lj post...
then i finish making a new animated icon for lj.
then i decide to take a lil BREAK and go to my "reading room" (bathroom)
i'm skimming over articles in infoworld magazine, and notice an article on a new high speed switch!
i think cool!! so reading reading about this cool new switch... and then this hits me... :
"we're a fully dynamic site generating 1,500 to 2,000 pages per second. being dynamic and not just pushing static files around, we often find ourselves cpu -bound. the less work our back-end web nodes need to do to generate the pages, the more overall cpu we have to work with," said F5 user Brad Fitzpatrick, creator of the blogging site Livejournal.com.
CHRIST BRAD, IS NOT EVEN MY BATHROOM SACRED?!?!?!?! YOU THINK YOU COULD GIVE ME A FEW MINUTES TO MYSELF?!!?!??!
What do you use for speed testing?
Speakeasy has a speed test page at each of their remote dns servers, 2 hops from the user; in Brad's case it would be sfo.speakeasy.net (I'm guessing that's what he used)

I didn't know of that. Plus I can't "download the plugin" because I'm on Linux.
I just did an HTTP wget from my server at Internap.
It's just java, I think linux can do that now.
The dns server is sitting next to your gateway, so it should give you the best test of that portion of your line. I guess staying on internap's network shouldn't introduce any bottlenecks, but I also wouldn't put any money on it.

Ah, I guess I don't have Java installed at home.
I'd buy one. I mean, if I could afford it. And if I had HDTV.
Welcome back to the fully connected world.
Can Dana be trained to build high-def MythTV boxes to take care of both the job hunting and MythTV matters in one step? :)
Well that would take care of step one: Train Dana to make MythTV boxes. Step two is a little more complicated: ??? Then of course there is step three: profit.
P.S. I am so very sorry. =(
Step 4: introduce Dana to Dina and hope they get along.
Step 5: make sure I don't make typos when typing drop table commands.:)
Dana, being the evil twin, never really got on with anyone. Especially not her happier, less-evil sister Dina. Dana however was much better at monotonous tasks like assembling PCs and therefore was the obvious choice to run the MythTV assembly line.
P.S. More apologies: Sorry Dina.
Sounds like you've got the MythTV thing pretty well in hand, at least theoretically, but n_tropy
's last umpteen posts have been about his extant and evolving setup, fw[ever]iw.
Just out of curiosity, do you know of any HD card w/ onboard hardware encoding? I have a MythTV box set up using the Hauppauge WinTV-PVR for standard TV, and I erally want to get an HD card before July, but I'm trying to use a C3-800 so I'm not using up too much power...

HD cards don't need to encode... the digital signal is already MPEG. So it just passes it to the disk or a decoder. So get an Air2PC or a PCHDTV-3000.
Oh. Don't I feel silly... In that case, why does the PCHDTV say it needs a 1200 MHz CPU?
Also, are you using a sattelite, broadcast, or cable input, and does the card care?
2005-03-06 07:28 am (UTC)
Needs more CPU to decode an HD stream.
The PCHDTV can only do broadcast (or maybe unencrypted cable).
