I thought 5 GHz was the solution to urban congestion by having lots of channels and poor penetration. I've never seen it get too crowded and I've never seen it travel through more than 3 walls.

Re: But then how will they track you
It will definitely be time to worry about offline tracking if Google changes their mind about storage cards.
Re: Can we finally settle this?
Lightness, chroma, and sync are encoded with different frequencies, response curves, and emphasis. There is noise and dropout masking because the tape signal is quite dirty. Later models encode a stereo signal into the drum head too. I'm not sure why, but there are always pots for tuning the horizontal and vertical alignment between even and odd frames.
I just took apart a Betamax to help digitize some tapes. It has one large control board, two large analog processing boards, an RF daughter card, some small servo boards, and a speaker driver board. Most of the boards have all wires exiting on the same side so that you can put the player on its side and fan out the boards like an open book. I honestly don't know why it drives speakers. That was a mystery even when it was "state of the art."
Re: Can we finally settle this?
For image quality - absolutely. Betamax was comparable broadcast quality on a 19" TV while VHS looked smeared and had almost no color resolution.
The opposite may true of mechanical quality. The Betamax tape path wraps almost completely around the drum head from one side, snaking through many polished pins and rollers. It would damage tapes with even the slightest misalignment and getting all those parts cleaned and calibrated for a good picture was pure magic. Players had slack sensors and multiple drive systems to regulate tension. Tracking was always fussy. Fast-forward and rewind were slow because the tape either had to unwrap and rewrap or it had to travel slowly enough to not fly off the path.
VHS pulled the tape straight out and pushed it against part of the drum head. The reduced contact path gave VHS a lousy picture but simplified mechanics.
Both systems needed fancy computers to convert encoded video signals that were at different resolutions between tape and TV. Early models literally had stacks of analog computer circuit boards filling those bulky boxes.
Name and shame
Sort those IP addresses, do the lookups, start naming hosting providers, and start building blacklists. Call BS on every network that claims they're too important to need an abuse response team. I bet the blacklist attenuates the attack very well with only a handful of networks placed in it. It doesn't catch any hackers but it takes their toys away.
It was indeed a stepper motor in the Apple ][ floppy drive. Head movement came from a spiral grove on a cheap plastic disk rather than the usual metal screw. The clacky-clacky-clacky boot sound was the calibration procedure - spin downward for a long time and let the needle skip. Track positioning and sector alignment was all performed in crude software so it needed massive physical padding. Spindle drive was your average cassette tape player motor - brushed motor and a simple negative resistance circuit to regulate speed. There was also the legendary bug where sector interleaving was wrong, resulting in throughput of about one sector per revolution. All this is why there were hacker DOSes that ran 8x faster and sometimes boosted floppy storage.
The Apple ][ was obscenely crude, lazy, and overpriced. Everything was a cool trick that wasn't quite right. It was endless educational fun for recreational hacking but excruciating for business software.
There's a specification for dumb chargers where the data lines are shorted together and current is negotiated by monitoring voltage droop. Despite some warnings that exceeding 1 amp may not be a good idea, many chargers provide 4 to 5 amps. USB 1 and 2 data devices are limited to ~1 amp because you don't want the power lines to have less voltage than the data lines.
Old USB allows up to 5A for chargers. With such a low voltage used, it's difficult for there to be more than 2.5 W of losses before the power consumer no longer has enough voltage to function. 2.5 W lost across the length of a wimpy cable won't generate much heat. 0.5 W lost in a heavy cable with 2 W lost at a spot of fraying sill won't generate much heat due to good thermal conduction.
I could be reading the spec wrong, but it doesn't look like the resistor needs to be there except to possibly improve efficiency. USB-C high voltage mode needs a data handshake.
Re: Gated reverb is luvverly (especially with a bit of reverse)
The 80's also had a good level of dynamic range compression that helped give it that sharp and clean sound. Amplitude was often too choppy in the 60s while today it's puréed droning.

Engaging new paradigm of synergistic integration
I don't want to register my desk to activate it, spend hours tracking down desk malfunctions, receive e-mails about new desk opportunities, view personalized content related to my choice of desk, become park of an online desk community, enter a walled garden of compatible surface objects, plug my desk into an outlet, or upgrade my desk every two years. Do not integrate tech into to my desk.
You might notice that your tinfoil hat is heavier than usual and has some small protruding wires. It's nothing to worry about. A figure in black suit sat on it by accident, felt sorry, and made some repairs.
I can see bandits defeating a heavily loaded surveillance system by dressing up as large swaying bushes to raise the H.264 bitrate.
On to something
These ceramic cases could be a big deal if OPO/OPPO can work out the manufacturing issues. Aluminum needs to be sliced up to pass RF, glass can't handle impacts, and reinforced plastics flex too much. Too there aren't enough LTE bands on that phone.
It was an "accident"
After reading the specifications, the mission, and what it looks like. Yeah, accident.
Never buy a telco branded phone - they're custom OS builds that don't get updates. Buy the OEM version.
What's the hot iDevice? Fanatics in the Apple ecosystem probably already have the late model iPhone, iPad, Watch, or Mac that they want. Recent upgrades have been minor technical bumps and more iOS/OSX convergence - nothing to stand in line for. That leaves the Apple TV as hot a gift item, and I don't see it racking up $77,000,000,000 in sales for Q4. Maybe five or six Apple pencils will sell too.
Surely Apple will personally follow up with The Reg to provide details.
Junk drawer chipset?
Why the worry to combine all of the WiFi protocols into one box? The access point could be a little box with a 10/100 Mbps PoE jack and a simple web interface to set power levels and authentication. The typical "WiFi VPN Firewall Router with dual WAN, dual USB, and 4 port switch" monstrosity is already so complicated that most people don't have them working correctly.
Aw, poor Dyson
Maybe Dyson is upset because those centrifuges and layers of filters result in an incredibly power hungry vacuum cleaner that doesn't move much air, regardless of how fancy the motor is. On the positive side, a Dyson consumes less power when those filters that never clog or need changing become clogged or need changing.
The new spec looks awful. Like the old QuickTime/MP4 container, it requires two passes to assemble so it can not be streamed live. It's not clear why they bothered with broadcast metadata. I also saw no mention of compression, phasing/placement metadata, and all that good stuff needed for high quality surround sound to work. Their sample has two tracks of PCM stereo plus six tracks of PCM 5.1. Ouch. That's not how 5.1 works.
I'm impressed that some parts of Sprint are fast enough that anyone could hit 23 GB in a month.
The very worst part is that people still somehow manage to make purchases without seeing ads. It's almost as if they weren't even... No, that can't be!
The 1980s called; wants to sell you a pocket TV
Early models of LCDs did this naturally and it was extremely costly to fix until recently. Maybe somebody found a huge stash of old screens after buying the Palm campus.
Sure, 'Pan' got terrible reviews and the "Pirates of the Caribbean" series seems to be forever undead, but I don't think pirate video needs to be illegal.
Please clean every ten whiskers
Part of the physics behind this razor are sound. You constrain a medium power laser within a light pipe using total internal reflection. As soon as a whisker contacts the light pipe, the laser will leak out and burn the whisker away. A smart circuit could vary laser power so that it's only running on high when the light is leaking.
Now for the bad part: A dirty light pipe doesn't work. Every bad cook knows that burned proteins and oils stick to anything, and more heat makes it worse. I doubt anyone has yet invented a tiny light pipe that will keep itself clean without lots of smoke, burned skin, and maintenance.
Re: Cambridge boffins
There's more to malware than botnets and lost files. Much of what's in Google Play Store is garbage of some kind trying to get easy ad revenue. You might think you're clean, but you might have a few impostor apps that do exactly what you expect but send ad revenue to a different developer. Or maybe they collect a bit of extra information of extra value. Lots of apps even have Google Play Store reviews with proof that they're malware.
Why did everyone bring a box to work?
The death of a big company: Management keeps getting bigger and bigger, processes get heavier and heavier, more accidents happen in the rush to maintain productivity, new processes are continuously added to prevent old accidents from happening again, no more real work can get done, and the chain of managers pushes down a mandate for everyone to work harder.
It's all a show to keep the team players happy. Maybe Musk has been hanging with Legere.
Not so many, really
There really aren't very many cameras sold on Amazon. Most of them are the same handful of cameras rebranded over and and over. Even companies that you'd expect to actually make cameras are sticking their label on something else.
This turned out to be extremely frustrating when I was looking for a security camera. Those few cameras have completely garbage firmware running under a patchwork of open source Linux software that somebody likely found on a sketchy FTP site 10 years ago. I'd open the box of a brand new camera and realize it was the same as the old camera. Default login won't stay off, pages not checking authentication, and much easier to crash than to keep running. I eventually started asking companies to send me sample videos so I could compare headers.
I'm guessing that TRENDnet was the vendor that said they have no idea what to do. Their TV-IP310PI is a defective Hikvision camera that they can't support. Other models may be similar.
Google Play Store is a malware wasteland
I consider it great luck when I find something in Google's Play Store that isn't malware. Google doesn't take abuse reports seriously, if at all, and they still require G+ signup to rate apps. The author of the software might have good intentions but it's hooked up to an ad service that hijacks the app. First launch shows "This application needs an update for media library v2" or "This application is no longer supported. Please use the current version." then starts installing more crap if you don't decline or uninstall. That's followed by endless half-assed phishing ads like "This iPhone is infected. Click here to repair."
Remember the good old days when humans were customers rather than marketing targets?
Re: Google has also sought to make the Google Now virtual assistant more prevalent with Marshmallow
Google is the new evil carrier that throws gigabytes of battery draining shovelware onto your phone. I wouldn't recommend their customized OS any more than one from a telco. Third party AOSP builds are nicely trimmed down.
Is this to streamline creating those spams that redirect through Cake Marketing/Rackspace then land on an Amazon hosted phishing site? It looks like it was a lot of effort to create them yet I get many per week. The next product can sell templates for the usual fake store fronts - pharmacy, company, solar installer, courthouse, package delivery, photo sharing, etc.
Re: Customer Disservice
Service was always prompt for me. I'd bring the phone to their store with a problem and then they'd return it minutes later saying, "We erased everything and did a factory reset so it's probably fixed now. Bring it in again if it has more problems." I bet they proudly displayed statistics showing that people rarely returned with a problem after the first service.
Re: Nice video.
Good catch! The back side of the tail wasn't blurred to match the low quality camera and the mask is slightly misaligned.
Re: Biiiiiig data
Marketing-centric retail is hard. They likely very prices for each item based on many static and dynamic factors. That results in an enormous and ever-growing hidden catalog to support a consistent experience each customer. They'd also be recording as much tracking data as possible for "customer retention" programs and marketing pattern analysis. Throw on top of that millions of single-use coupons, reusable promo codes, customer-to-customer recommendations, gift cards, billing information, and hopefully some fat crypto. Now it's getting to be a big database.
So what does Oracle, owner and destroyer of Java, think of this? Anyone checked the height of Larry's fountain at HQ?
Checking my Silicon Valley address...
Across the street from new LinkedIn, Apple, and Google campuses, AT&T is offering 3 Mbps to compete with Comcast's 0 to 150 Mbps. For those not satisfied with having just AT&T and Comcast to choose from, there are two other internet companies that can resell those same connections at much higher prices.
Re: Still don't want Chinese Kit!
As an owner of an Chinese phone, I can assure you that the OEM software is not sending your personal data to China. It's sending all of your minute-by-minute personal details Google, like every other stock Android phone. The good news is that the Chinese phone makers let you replace the stock OS with one having a bit of privacy and decency built in.
White LEDs are inefficient when hot but they're hardly hurt by it. I overloaded some to test what would happen if their regulator failed. Over and over again, the LEDs would unsolder themselves before suffering any noticeable harm.
My guess is that the phone is protected with PTC fuses - little components that stop conducting while hot. They can protect against wire fire, battery damage, and overheating due to software malfunction. The downside is that they aren't a good match for modern heat tolerant components. They'd have a very downgraded current threshold in a phone.
The biggest problem with cheap high-spec phones is the lack of LTE bands. Most of them have two sets of two or three diverse bands to choose from, with hopefully one set having one band that is used in your region. The OnePlus Two is better than average in this respect. I count 8 LTE bands in the North American model.
"cable was too short to reach the socket"
The perfect metaphor for this design show.
Re: Has anyone got any real details?
Modern cars tend try to run the engine at heavy acceleration as much as possible for efficiency. The gas pedal modulates the transmission to use the highest gear possible for the desired power. Extra RPM is extra friction and extra exhaust. This has been the only trick left after already optimizing combustion, accessory loads, tires, transmission, aerodynamics, etc. This is also why modern AT cars have such terrible acceleration lag. The engine is already near maximum torque so you must wait for a gear change.
The old days of Skype
Modern cell phones can do text messaging, voice calls, and they're starting to get video chat. My cell provider does cheaper International calls for $10/month. My landline is toll-free to much of the world and has better rates than Skype when there's a fee. Best of all, none of the non-Skype solutions will seize your account balance due to "fraud" when you make a call from a foreign country.
I don't think you can call it a cloud if it's all in one datacenter. That's just called a "datacenter".
Maybe in trouble
NOx is nasty stuff. It eats through engine parts, sidewalks, sculptures, buildings, soil, eyes, lungs, wildlife, and pretty much everything else. The trick will be for VW to fix the emissions without a class action lawsuit for the car no longer meeting advertised specifications. If VW was running the combustion chamber extra hot to meet soot regulations, then they're definitely facing a technical nightmare at this point.
The path off MacOS
I have an original "Mac Mini Server" running MacOS 10.6. I know that an Apple upgrade will destroy every single configuration it has so the logical choice is a new Linux box. This nice set of instructions will probably shave a few hours off setup when that happens.
Solid 7Mbps ADSL or 0-75 Mbps from Cable?
I'm sure it will make my 3Mbps video streams really come to life. (as long as I'm not getting an e-mail at the same time)
And the music player
At least in CM12.1, you can crash the lock screen if a song is playing. Just hammer all of the mini player's buttons as fast as you can until the OOM killer makes a visit or things start to crash.
Re: Next up
Somewhere there's a big database of every link ever found in a private message, and I'm betting that it's pretty easy to get other people's original URLs back out. Each recipient who clicks a shortened link is going to generate an access log entry. That's how it's not even remotely private.
They could get around this by not substituting the entire URL. Just substitute the domain and throw the rest after a '#'. A sent URL of "http://some.domain/private/secret/mystuff" becomes "https://t.co/domaincode/#private/secret/mystuff" when received. The part after the '#' anchor delimiter is never sent to servers by browsers but Twitter could return a document that can see it and reconstruct the original URL. Advertising metrics would be reduced but not entirely lost.
