Custom-Made 3-D Earphones

hamsteralliance says...

Etymotic offers earphones with removable tips and the option for custom-fit tips. For those, you go to an Audiologist, get silicone impressions of your ears, then send those off to a place that'll turn the impressions into earbuds that are exactly the same as the inside of your ear. Perfect fit with incredible noise isolation.

It's as pricey as it sounds, but since they're just earphone tips, you can use them on other earphones and not have to redo the process.

CNBC Host Accidentally Outs Apple CEO Tim Cook as Gay

DuoJet says...

This guy did not "out" Tim Cook. Matter of fact, Tim Cook was called "The Most Powerful Gay Man in Silicon Valley" by a Gawker property in 2011. The dude is gay. Those who give a shit about such things already know about it.

So what are we talking about?

Using Science...The Most Efficient Way to Jerk Off 800 Men

artician says...

This whole show's premise fails simply because it takes place in Silicon Valley, yet features no Asian ethnicities, which unarguably own Silicon Valley.

Sixty Symbols -- What is the maximum Bandwidth?

charliem says...

Fibre can go a pretty long distance before it affects the signal though...

Fibre is comprised mainly of silicone, the more pure the fibre, the less dispersion issues occur at or around 1550nm (one of the main wavelengths used for long distance transmission, as we can easily and cheaply amplify this using ebrium doped segments and some pumps!)

Any impurities in the fibre will absorb the 1550 at a greater rate than other wavelengths, causing linear distortions in the received carrier along greater distances. This is called Brillouin scattering.

In the context of the above video, consider a paralell cable sending data over 100m. If one of those lines is 98m, then every bit that is sent down that line, will be out of order.

Same deal with Brillouin scattering, only on the optical level. Thats one of the main issues we gotta deal with at distance, however it only ever occurs at or around 1550nm, and only ever when you are driving that carrier at high powers (i.e. launching into the fibre directy from an ebrium doped amplifier at +15 dBm)

Theres some fancy ways of getting around that, but its not cheap.

Anywhere from say around 1260 to 1675nm is the typical bandwidth window we use today.

So, say 415nm of available bandwidth.
If we want that in frequency to figure out the theoritcal bits/sec value from the shannon-hartley theory, then we just take the inverse of the wavelength and times it by the speed of light.

7.2239e+14 hz is the available spectrum.

...thats 7.2239e+5 terahertz....

Assume typical signal to noise on fibre carrier of +6dB (haha, not a chance in hell it would be this good across this much bandwidth, but whatever..)

For a single fibre you would be looking at an average peak bandwidth of around 20280051221451.9 mbps.

Thats 19,340,564 Terabits per second, or 18,887.3 Petabits per second.

You can fudge that +/- a couple of million Tbps based on what the actual SnR would be, but thats your average figure.....thats a lot of Terabits.

On one fibre.

Oakland CA Is So Scary Even Cops Want Nothing To Do With It

Oakland CA Is So Scary Even Cops Want Nothing To Do With It

Velocity5 says...

Thanks for the links. I'm new to advocating for states' rights

> "What is the optimum size political unit for you?"
My main concern is SENS and reprogenetics for everyone who wants them. Making my purpose in life to be building my career maximizes my odds of making it to SENS. I'm fine with living in huge nations as long as taxes are low, law and order are maintained, and the government is fiscally sound. But I think all 3 of those issues are going to be under increased pressure.

>"Would you consider yourself Right-wing?"
No, I just consider myself a science and tech nerd. When I debate with right-wing people, they think I'm a hippy. I'm too self-reliant and career and family-focused to really care much about politics. I think we'll eventually have a Star Trek world. I dislike any trends that seem to make that outcome less likely.

But I read enough science to know that wool has been pulled over our eyes about human evolution and inequality.

>"What would you consider to be a meritocratic utopia?
I think Silicon Valley is the closest thing we have to a meritocratic utopia.

>"Why not scale it down to counties and municipalities?"
In my work, I collaborate with people on the other side of the country. It's best for us to work with them than with cheaper people in Ukraine or India because we share a cultural background and are within the same legal environment. It'd be much harder to take legal action against someone in other countries, and that means parties can't have the level of trust afforded by shared legal protections. Commerce increasingly interconnects the world, and dividing large jurisdictions into many smaller jurisdictions would be a drain on commerce.

Velocity5 says...

@Buck said: "We should close factory farms and teach people how to hunt again."

Hunting can't scale to support a larger population than a hunter-gatherer tribe. So the cost of meat would skyrocket because demand stays high, and supply can't increase.

Meat costing $75 per pound instead of $5 per pound would be a huge reduction in quality of life for everybody.

That's why humans left hunter-gatherer lifestyles in the first place.


The answer will probably end up being the vat-grown meat Silicon Valley is working on now. It will be the health equivalent of organic and free range meat, since it's not fed pesticide food, antibiotics, etc.

How Germans Say "Squirrel."

coffeejerk says...

According to http://www.princeton.edu/~achaney/tmve/wiki100k/docs/Squirrel.html The word squirrel, first attested in 1327, comes via Anglo-Norman esquirel from the Old French escurel, the reflex of a Latin word sciurus. This Latin word was itself borrowed from Ancient Greek word σκίουρος, skiouros, which means shadow-tailed, referring to the bushy appendage possessed by many of its members.

Seems fine if correct.

And @chingalera you can one i from aluminium. As long as you stay away from silicon .

L0cky said:

Would think it'd sound more like 'skwiro' in Clapham; though there is a high chance your friends in Clapham were Polish

I fully defend the i in i-um in aluminium though. You wouldn't call helium helum or uranium uranum.

I'm guessing it only got bent into 'aluminum' because it became a popular and cheap element to manufacture with, so it entered the pop lexicon of America and got softened up.

History of VideoSift Part III (Blog Entry by dag)

dag says...

Comment hidden because you are ignoring dag. (show it anyway)

The introduction was more of an email hand-off, I think Battelle and I exchanged a couple of mails and that was it.

A bad taste is the right way to characterise that session in San Francisco. I was left feeling that I was completely out of my league in the world of Silicon Valley business.

"siftbot votes that can be reclaimed"

The ability to reclaim votes seems to have gone away. I was actually about to post to sifttalk about it yesterday, but didn't get around to it. And since it specifically came up here, I thought I'd mention it.

Great work again, @dag. Though I admit I was hoping to read more about "K" and Battelle. Did that introduction ever happen? Did Battelle have any good insights for you? Did you get anything other than a bad taste in your mouth from that meeting?

First Video Clip of Ashton Kutcher as Steve Jobs

chilaxe says...

Woz recently said that this scene has nothing to do with how things actually were.

I was looking forward to this being a smart movie like "The Social Network," but this clip makes it looks like it won't be as good as the old Pirates of Silicon Valley movie with Noah Wyle portraying jobs.

The Woz actor captures nothing about Woz. The only reason we can guess he's supposed to be Woz is he's heavy and has a beard.

"Gone, Gone, Gone" - (Rhode Island Teacher Says "I Quit!")

chilaxe says...

@rebuilder

There's very good data showing test scores correlate with all socially valued outcomes.

That includes professional development, health outcomes (managing our personal health in the 21st century is complicated), lower divorce rates, lower rates of out-of-wedlock births, lower crime rates, etc.

I agree, however, that school is mostly useless. I encourage young people to get their highschool equivalency at age 12-16. Get a 4 year degree if you absolutely must, but do it as fast as possible. Aim to move to a tech hub like Silicon Valley or Austin, Texas to become a programmer, designer, marketer, bizdev guy etc.

Popping Balloons With Lasers On QI

charliem says...

The balloon is basically vulcanised rubber, or more commonly known as latex. The lasers I work with have certain interractions with the water content in silicon fibres. Different wavelengths (colours) react differently within different fibres.

1550nm for example sits just on the absorbtion point of water in silicon, so it loses quite a lot of its energy along a fibre due to that water absorbtion in non-pure fibres. 1310nm lasers however dont have this issue, and can hold their signal for far greater distances.

Different coloured lasers, interacting differently with the exact same material.

One has its energy absorbed, one doesnt.

.....im guessing a similar principle occurs here.

(Im in telecoms if you hadnt guessed )
