Fans of "How it's Made"

I find this stuff endlessly fascinating. Here's the Motherlode:

I retired from Teamster's Local 631 in Las Vegas. We used to set up conventions. We used to have the "Pack Show", a show for automated machines of all types. It was a lot of fun setting up, because I always worked rigging, and getting those components together was fun and challenging. But once they were together, watching them work was awesome. Most operated at a speed that could only be called a blur. Then they would slow it down to see how it was actually done.

I love that program, and it always answers questions I have had on "How do they get that to do that."

?Why does this video have so much lag?:

?And yet there is not lag with this one?:

In a word: Timing

I looked at both just now and saw no delays. Of course it's 9:30 on a Sunday morning. I expect them both to be pretty jerky by Monday at 10:00 AM.

It still runs for 6 seconds and lags for 4 seconds for me.

Perhaps your local server is choking? Can you create a new newsgroup account pointing to

see if that speeds things up?

But there is another factor to consider. The first video connects to youtube, and then from there connects to

to get the actual video -- so you have two systems which you have to access, doubling the chance that one of them is busy. If you look closely at that URL, it can be broken into two URLs. I'll copy it down here and break it for you:

This one connects to the other -- note how it ends with "url=".

And here is what followed the "url=" to give you the actual URL where the video lives.

I proved this to myself by entering just the second part into my browser, and was able to view the video with no problems (near midnight on Sunday, FWIW.)

I wonder how common it is for youtube to link through to another site as they did here?

Enjoy, DoN.

Thanks, DoN. I suspected that. Bottom line is a net bandwidth issue, I think.

Apparently links are very popular. Have a look here:

It gives one the impression that the NAM videos are hosted by youtube directly. It seems reasonable that they would have youtube do what they do best. Makes me wonder just how complicated this link structure could get:

Youtube linking to NAM shopfloor.org linking back to youtube?

Say it isn't so! :)

On Sun, 05 Oct 2008 21:24:30 -0700, the infamous Winston scrawled the following:

(Midnight Sunday is a real high traffic time, isn't it, DoN?) But, yeah, parsing URLs does cut out some of the middlemen and is a Good Thing(tm) in any case. Good call.

Very possible, but add to that: 'lebenty seven servers in between, relaying the video to your server between countries/states/counties. That's an everyday "web" fact of life, Win mon.

Larry Jaques related in his avuncular manner:

Yup, and the bandwidth of those servers, on average.

What I know about TCP/IP you could put in a thimble and still have room for a medium size battle ship. I suspect that packets are routed to maximize throughput & minimize latentcy. The frequency of video interruptions is inversely proportional to the average 'width' of the internet "pipe", I conjecture.

What I found cool is listening to music online through separate ISPs. Sometimes one computer would be ahead and then loose out to the other. Guess they get rerouted and delays are noticeable.

That sort of thing is quite noticeable in the UK where we have analogue and digital television transmissions. If you have a digital TV playing in one room and an analogue TV in another viewing the same channel the digital has a few second lag in the transmission.

I get the same effect when SWMBO happens to be watching the same TV channel as I am watching. My TV is directly on cable and audio reaches my ears through wireless earphones, while her signal goes through a "PVR" box and audio through speakers on the wings of her chair, all this in a 10 x 12' room. Her audio lags mine by about a second or more. Gerry :-)} London, Canada

You want fun -- try talking (or reading a script) while earphones are feeding into your ears your own speech with a second or two delay. :-)

Enjoy, DoN:

I made my own "hows it made" and then the real Hows it's Made showed how to make a brass instrument:

Here's mine:

Bravo! Encore!

Damn fine.
