In fact, you could take it a step further and apply Bernoulli's equation to the fluid in the system. The difference in pressure between the source reservoir and the destination reservoir is exactly offset by the effective pressure loss due to friction between the flowing liquid and the tube wall.
The difference in pressure between the source reservoir and the apex will include part of this friction pressure loss (proportional to the length of the tube from the source to the apex relative to the overall length) + reduction in pressure due to the velocity of the fluid in motion (static liquid is at a higher pressure than liquid in communication with it at the same elevation but in motion -- the principle behind the pitot-static tube).
This is why flow through the siphon can be regulated by raising or lowering the apex of the tube. Make it higher, the total friction pressure loss is increased and the velocity must decrease to offset that loss. At some point, the tube is sufficiently long that the flow is slowed to a standstill.
Furthermore, they completely forgot the obvious ethical dilemma of an InfoWorld web site programmer tasked with implementing multi-paged articles.
Slashdotted. Problem solved.
Business is ... axes? or split firewood?

Reinventing the Axe
·
· Score: 1
I watched a few promotional videos for the Vipukirven on YouTube. People lined up at trade shows to try out this new axe, and the promo guys were kept busy heaping the resulting split firewood onto a huge pile. It occurred to me that touring a "new axe" around to trade shows and getting passers-by to split enormous piles of wood for you for free is a great business model for a firewood vendor...
Of course, if you can sell the occasional axe (for US$200+), so much the better!
A lot of the blame for Win8 can be shouldered on Steven Sinofsky, who by all accounts thought himself as a cross between Steve Jobs and Napoleon. He was given free reign over Win8 due to his perceived success with MS Office (and the ribbon interface).
As is always said in these situations, find at least one scientifically rigorous study showing any alternative medicine works.
Nope. You have to find at least two such studies, the one reproducing the results of the other to a high degree of similarity. Otherwise it's not scientifically rigorous.
Wait! You're right! The study is seriously flawed! Mice already stay up all night; they're nocturnal by nature. So how could pulling "all-nighters" cause demonstrable brain damage in animals that have a natural predilection for so doing?
Totally agree. What's more, you can't be in the multimeter business and NOT be aware of Fluke; they've been prominent players and frontrunners in that business for literally decades. Sparkfun had to be aware of Fluke's product line, but they went ahead and chose a yellowish-orange border colour anyway. "Army of consultants or attorneys" indeed! Serves 'em right.
In short, I am forced to obtain citizenship in my country of residency, and give up my citizenship in the United States.
Not so fast, Round-Eyes. Before you can renounce your US citizenship, you must sign an oath to that effect at an embassy or consulate outside the US, pay a fee of $450 andsettle up with the IRS first! Only when the latter have agreed that you have nothing outstanding may you no longer call yourself an American. Otherwise, sorry, Bud -- you're still in!
The AHS publication of the Sikorsky prize regulations, Flight Requirements 4.4.3, states that "a reference point on the non-rotating part of the machine will be established as a means whereby the observers can judge that the machine stayed within the confines of the 10-meter square", thereby clearly indicating that one point on the machine must remain within a 10 m x 10 m square, not the entire machine.
Your memorial site for Sue is a thing of beauty. It brought me to tears. Thank you for sharing it with us. Sue was as lucky to have you in her life as you were to have her in yours.
Wasn't there a case something like this one back in the 19th century? Spurious accusations, suppression of evidence, unjust convictions. Some guy named Dreyfus, I think...
I wonder if our collective social conscience is as responsive as it was back then, so long ago.
And how long will it be until extremists design and assemble a lethal and unstoppable virus this way and trigger a global epidemic that wipes out humanity in the name of Allah? Nice work, Omri; you've just handed them the tools.
I tried Kingsoft Office and was fairly impressed with how closely (cleverly) they'd cloned the Office 2007 interface. Quite useable for the few things I played with (mostly the Word, Excel and Powerpoint equivalents).
The liberal-conservative taxonomy in the study is based on a simple premise:
- brain activity detected: liberal
- no brain activity observed: conservative
See? Pretty easy..
LOL. Wish I had mod points to give you. Cheers!
And also with you.
Amen
... means that I am the team idiot -- for better or for worse.
Great explanation! Completely agree.

"To be the master of the machine, you have to have the knowledge and the skills to teach the machine."
Boy, there are some deep lessons and insights here for the Facebook / Twitter / app-for-everything user generation.
Learn how to use the machine -- or the device -- or it will use you.
GrahamCox was being a smartass (and/or trying to be funny) -- but thank you for your patient and informative response! (Wish I had mod points left ...)
I read Hesse's "The Glass Bead Game" long before the Internet even existed, and it was completely fucking opaque even back then.

Yeah, everyone loves that.

'It sounded like I was involved before with bitcoin and looked like I'm not involved now. That's not what I meant. I want to clarify that,' he said.
So ... you meant that you are still involved now? I think I see what you're saying, Satoshi/Dorian ...
... live longer and prosper.

Go fuck yourself. Thank you.

One caveat: it's from a Chinese publisher.
