Waterfall Niagara speakers

Dampening is there

I've thought about building speakers like these for my home even before I saw these pics. You'll see from the photos that there are large dampeners around the woofers, holes in the passive resonator, and there's room for more dampening under the passive. My cost estimates were far lower and I still couldn't justify it, not even when it's a speaker, a sculpture, and a hobby project all at once. I was also going to use polycarbonate because it won't crack.

Miniature Apple display spotted in the wild

Probably is a trackpad prototype

The long cables imply that it connects to something large like a laptop. Two complex cables implies two separate functions. There's a colored pattern on the screen that's too chunky for pixels but they could be light interference from touch sensing conductive films.

A visual trackpad sounds very cool but it would be useless without a new GUI paradigm. I doubt Apple wants so many GUIs at once - Mouse/Keyboard, Keyboard with gesture pad, Keyboard with visual gesture pad, iPhone/iPad, and iPod.

Perfect for watching YouTube

Where is the need to send 21.6Gbps of video long distances? Not even in 10 years will there be a consumer device that can source that much REAL data. It makes more sense to send the video in its original storage format, which will remain 5 to 100Mbps for quite some time, and decompress to high bitrate pixels at the point of display.

100W over Cat 6 - It would take about 45V @ 1.2A on each of the four pairs to survive 100m. Fire icon, because thats what would happen if you had a coil of extra HDBaseT behind your TV.

No shifting

Fancier electric motors work fine with a single gear ratio. Moving the torque curve can be done by changing voltage ranges, changing windings, or by mechanically moving the magnets.

I don't know why you're having traction control problems with an automatic gearbox. Good cars have precision control over wheel spin. An electric motor would be even more precise and a rat's nest of complex brake modulation plumbing would go away. It's just a matter of the engine control computer in an electric car knowing how to do it.

My only gripe about electric cars is that they're still lacking refinement. The technology isn't mature enough to build an affordable electric car that is durable, sporty, and efficient all at the same time. This car comes close but I have my doubts that being efficient for only the first 40 miles is good enough.

Uncool

Sure, Adobe went stale after the 1990s but many of the attacks were undeserved. Advertisers' desire to consume as many resources as possible will persist whether Flash exists or not. Remember high frame rate animated GIFs that looped forever? Advertisers will drain the battery with poorly coded H.264 and JavaScript animations too. Last time I checked, QuickTime wasn't any less prone to crashing than Flash, either. It's great to ban Flash because of its obsolescence but Apple's barbs will come around full-circle.

Blocks referrer

I searched for my own site while watching the server logs. With plain http, a click produced my full Google query in my logs through the 'Referer' header. Https scoping blocked the referrer data, so this does have some value. Malware sites won't be able to create customized fake pages and it will prevent a dozen web sites knowing that you searched for "rapid corpse disposal."

It's good news for Google too. It makes their collected data very exclusive, and Google is all about making money from data.

Version 1.0 has lots of problems.

Like IR, but more invisible

60GHz sounds like it's going to have all the hassles of IR but with higher costs. What IR tech always lacks is a temporary visible beam to assist aiming. With a visible guiding beam, you could chose a common location on a wall or ceiling for all devices to bounce their signal off of.

Applesoft, Ogg, and the future of web video

AAC

A critical factor not mentioned here is codec efficiency and quality. A poorly performing codec can drive up bandwidth costs, drive up the cost of encoding hardware, or provide a poor customer experience. H.264/AAC was chosen as a standard by many large companies because it completely blew away other codes at the time. Suddenly home users could stream high quality video without exotic internet connections or hours of buffering. To also imply that H.264/AAC will be the future standard is ridiculous. Codecs come and go.

Popcorn

Apple could simply have power drain specifications to reject inefficient apps. Bad code comes in all forms so the coding language restrictions do a poor job of hiding Steve's raging ego. There are also certain tasks where JIT-compiled JavaScript, Java, Perl, etc. can run very efficiently.

Developers using Flash rarely have intentions of efficiency. It's too often a short-cut language for rapid offshore development. Adobe can run a big angry lawsuit only to find all of their apps being rejected again on technical grounds. It's all going to be amusing.

Inkjet printers flush their liquid money into gutters at the edges of the page. It's a solution for stagnant pigment clogging the nozzles, with a pleasant side effect for the printer manufacturer . Thin font or fat font hardly matters. The difference ends up in a large sponge at the bottom of the printer.

Prior fart

I had a handheld TV that did this in the 80s. You opened the case partway and watched the LCD from a mirror on the base. There's a good reason for them not being made any more. Even with impossibly perfect optics, color LCD screens can never be more than 16% transmissive. E-ink is more efficient but it doesn't need backlighting contraptions.

Microsoft's dual-screen booklet shows 'face' on web

Concept demo

This is an early concept demo - the kind that Marketing departments show internally at regular intervals. They imagine the workflows of 5 to 10 target customers then display a product serving them. After this meeting, Engineering finds that 90% of the product's decisions shown in the demo were made without sufficient input parameters (magic is not an input parameter). Test groups say, "That's amazing, but can it..." Project managers add up the costs and find it too expensive for the target customer. The demo and the specifications are reworked for a couple of months and eventually the amazing magical product looks quite common.

Old trick

This trick is almost as old as the search engine web sites. Give the web crawlers content stolen from other sites. Give people advertisements and/or malware to real people. It's a simple matter of checking the User-Agent header.

There are similar tricks for malware hosting. A malware server or its name servers will show system administers a special page that appears to be operating normally or an error page saying that the site has been deactivated. Everybody else gets the malware, a fake store front, or a proxy for various uses.

Really 12.4?

The full-res photos don't seem all that sharp. About only high frequency components that I could find in Photoshop was noise. It reminds me of some research in the 90s on how to upsample media in ways that trick the brain into seeing a higher resolution image. I recall that high frequency noise was used to mask lost details, then your brain would then replace that noise with a very convincing assumption about what the details should be.

The high ISO photos look great. There's relatively little noise and noise suppression damage. Put a bright lens on it and take it into town at dusk.

Bio are in currents water, not air

Friction noise in air is not hard to detect. Hair, shoes, clothing, plastics, and sometimes stresses on the floor create significant amounts of electricity with every motion. This makes a portable device not so crazy to design after all. The real question is how many naked and hairless test operators can be hired with that $6m of development cash.

And the Roddenberry fans

Might as well bring the Jobs fanatics and Roddenberry fanatics together: Who hasn't admired the Star Trek PADD devices? Laptops are clumsy to carry around and anyone who has used one without a table knows the kind of stares generated by accidentally dropping it. There's a business use for a device that could display documents prepared for a meeting and have just enough user input for note taking. Give it the ability to dig through files on your desktop computer and maybe the laptop gathers dust. That's the Monday through Friday use. At home, like you said, it's for massive media consumption.

Apple preps touchy-feely iMac

Kevin McMurtrie

App control

A touch screen is very nice for app control, especially since Apple is pushing for Bluetooth peripherals. You can check e-mail, control music, start video chats, and perform quick maintenance tasks without the hassle of powering up the mouse. For this to make much sense the iMac will need a very low-power running state so it can be left running constantly without drawing more than a few watts. OS X, as it is now, can't spin down the boot drive and it doesn't seem capable of slowing down the CPU much.

FCC raises eyebrow at Google 'white-space' play

Kevin McMurtrie
Bronze badge
Big Brother

The plan is coming together now

According to Google, whitespace use is critical for the future of the Internet and it requires a geolocation database to protect public TV broadcasts. This forces the use of Google Location Services at the router, not at the browser where it's optional. Now Google knows where HTTP traffic originates within a very small area. Combine it with their tracking services, search engine hits, GMail, etc. and they have the ability to track everybody in every detail all the time. I don't think there's a shortage of bidders for that kind of data.

They don't remember the old days where having the keyboard and motherboard on the same box meant the cables in back pulled out after a few ergonomic adjustments.

Another?

I think the market is saturated before these hit the streets. Until charging and range problems are solved, all of these e-cars need a tiny diesel charging generator. Nothing big like the Volt - just something that can quietly work while the car is parked outside. As a generator, the diesel motor could operate at peak efficiency and take advantage of emissions controls that require high temperature exhaust. When close to home the generator won't be needed at all.

I don't see any environmental friendliness in needing to buy one long-range car and one short-range car.

FCC eyes 'over' 150MHz of TV airwaves for broadband

Kevin McMurtrie
Bronze badge
Flame

RF pimp

How is another 150MHz of spectrum going to give everybody fast broadband? Even if mankind invented a holographic electromagnetic modulation that improved efficiency 1000x... Well, high performance fiber optics are here now and the telcos aren't rushing to deliver that. Levine and Kirjner saying that we shouldn't rely on new tech says a lot about US bandwidth plans.

Why steal the bandwidth from broadcast TV? Because everyone uses cable TV instead? Cable TV coax has far more bandwidth yet customers receive a few megabits and threats of disconnection for abusive utilization.

The way the FCC does their job, "the country that has the best broadcast TV in the world" is too lofty of a target. All of those $40 DTV upgrade coupons exempted high-definition tuners, thereby ensuring that antiquated MPEG2 streams will encumber our airwaves for as long as the old copper wires trickle data to our homes.
