No reception tests? Has the UK abandoned sending TV over the air? It was only a few years ago that most ATSC tuners were running buggy MPEG2 decoders downloaded off the 'net that would crash on a little multipath distortion.

Samsung strokes big bulb that'll keep going for decades

WTF?

Dim one and bright zero

A digital technology LED lamp? The LEDs are analog and, in fact, much more efficient when they're getting less than 100% maximum current. The switching power supply is an analog computer that tunes the pulse width of an oscillator driving a low-pass filter.

New 'plasma lamps' to replace fluorescent bulbs, LEDs

Kevin McMurtrie
Bronze badge

Zap!

This is interesting technology but I wonder about longevity. Plasma isn't known for being kind to its surroundings. Can they seal the the micro-cavities so well that a flaw doesn't result in a tiny moving burn that slowly consumes the panel? If so, I have a lot of unreliable CCFLs that I'd like to banish from my house.

Comparisons to LEDs are always a tricky topic because the efficiency drops rapidly as the input power is increased. For a required amount of light there's a tradeoff between adding more LEDs to reduce heating or adding more cooling to reduce the LEDs. 120+ lumens per watt would be trivial if the high cost of LEDs wasn't influencing that tradeoff.

Here I was thinking that I'd need a counter variable in my h4ck3rz script to iterate through all four digit passwords, but then I watched the video again. The password is single-use and changes every time. That means I can guess the SAME 4 digit password over and over and it will eventually be correct by luck. Win!

Set the 'Beacon Interval' to about 1000ms and the Googly snoops will have a hard time seeing idle access points from a moving vehicle. It saves battery power on WiFi-assisted cellphones too. The only downside is erratic packet latency.

Welcome to bull 2.0

They will use the same trick as any filthy marketing company: rapidly rotating opt-outs. You opt-out of 'X', that confirms your account as active, and feature 'Y' debuts next week with you automatically opted-in. Only a firewall rule or a stronger lawsuit ends the cycle.

5 SECONDS to bypass an iPad 2 password

iOS, MacOS X, and Android

The problem is that the lockout app launches when the device is awakened, not when the device becomes idle. That creates an opportunity for things to go wrong. I've had my Macbook Pro and Galaxy SII run for several seconds unprotected because the lockout application's launch was delayed by heavy filesystem I/O.

Spamhaus and ISP spar over 'email DoS' blacklisting

Fixed it

A2B posted the full conversations with Spamhaus on their web site, along with their reports of criminal activity. I have to partially agree with A2B - It's not right for me to let Spamhaus choose whether or not A2B mail is blocked. I need a permanent blacklisting in my local deny list.

What about the stream of garbage coming off the CPU as the power fades? What about partially completed operations? It seems like the motherboard will also need a bank of ultra-caps so it can tidy up the RAM to a state that can be understood when power is restored.

ITU heralds ultra-high def TV progress

Kevin McMurtrie

Compression

There are few conditions where you can get 7680 × 4320 sharp pixels through a lens. It's a tradeoff between depth of field, diffraction, and random noise. The director of the video is also manipulating image focus and detail to direct your point of attention. In the end there aren't very many high contrast moving pixels. It's possible that H.265 squeezes a decent looking 8K x 4K video into the 15Mbps stream used by MPEG2 now.

Netflix: How to completely screw up

Kevin McMurtrie
Bronze badge

What would you like to watch again?

It's studios, not the price hike that killed Netflix. Netflix's selection of new streaming releases has gone from slim to almost none this year. Browse the new release section on their home page to see how bad it is. The price hike for disc renters only concentrated an exodus that was inevitable. I never rented discs but I left for lack of there being anything new to watch.

The C and C++ languages are not safe. It's their binding to low-level operations that lets them be fine tuned for performance. To suggest that a compiler can make C/C++ both safe and efficient is absurd. Lots of people would love to get their hands on such a piece of magic.

Does it record to Betamax or VHS tapes?

This proves that Sony is harnessing the power of time travel to design their products. Too bad they stole a prototype from 10 years ago. Next time they should try traveling forwards a bit so they have a product with proper stereo imaging, a microphone that aims forwards, magnification better than squinting, and something higher tech than an MPEG encoder. Where's the night vision? What about the pulsed laser trick that the military uses to find people looking back at you? How about compensating for atmospheric distortion?

Evolving, not dead

The big desktop computer isn't going anywhere but its form and uses will change. Socializing, communications, and information have been moving to small portable devices while desktops become more tools. There's ALWAYS a professional job that requires more power. There's ALWAYS a game that requires more power. There will ALWAYS be tasks where a tablet/laptop is not ergonomically matched for interaction. Even if telcos become saints and upgrade your stone-age wires, there will still be tasks where speed of light latency costs more than buying local computer. I wouldn't expect the desktop to lose its cables any time soon either. It could be decades before WiFi signals can be encoded in a way that is both fast and reliable.

iHassle

This can only work if the earbuds electrically touch the iThing. (If not, the field on the way out to the buds and on the way back to the jack match and cancel out). This is dumber and more cumbersome than simple designs that directly touch electric wires to a device.

Maybe you can wind and unwind the earbuds on the magno-pole a few dozen times while you're waiting for iTunes to stop hanging.

600 hurts my eyes

The 600Hz "sub-field drive" is the dithering rate that's an artifact of plasma technology. It's not a good thing to have, but a higher number reduces the likelihood of visible flickering on some shades and colors. At least in older models, the built-in Pandora viewer is one of those flickering shades.

You can photograph the sub fields using a sensitive DSLR camera. It's looks very strange.

We understand the urgent nature of your message...

Anyone who has tried to contact Google about criminal use of their services knows that they've built a solid barrier to receiving such information. They don't want it. They don't want expectations of being contactable. They don't want to be responsible for how their systems, maintained or not, are being used. I won't feel any pity if they're fined $500m for their meticulously crafted ignorance of illegal activity.

IPv6 intro creates spam-filtering nightmare

Kevin McMurtrie
Bronze badge
Thumb Down

Pick a better list

I find IP address blacklists to be extremely useful. There's a lot of address space that is completely unmaintained or owned by criminals. A blacklist is not only efficient to implement, but pressures the network into cleaning up or going out of business. If there are too many false positives you can use a less aggressive blacklist.

Content filtering is a losing game. The CPU power in hijacked networks always beats the CPU power in your analyzer. Finding ways to beat your filter is trivial and of no cost to the spammer.

You do not hold cable. Cable holds you.

It's disappointing that this seems to have become another fat cable technology rather than the sleek optical cable it started as. The DisplayPort cable on Macs is more rigid than Cat 6 and USB 3. It won't stay put and the tiny jack strains to support it.

Oracle gives 21 (new) reasons to uninstall Java

Kevin McMurtrie
Bronze badge
Dead Vulture

Evil Ellison icon, please

Uninstalling Java is a harsh recommendation from a web site that's hammering my Flash blocker and Web-bug blocker.

As a language, Java is very good for business applications. It's simple, has a rapid development time, and has growing support for multiprocessor systems. Most of the bloating comes from commercial "Enterprise" frameworks that attempt to eliminate boring boilerplate code with XML files. They run slowly, bloat applications, drive up costs, increase complexity, and usually take longer to use than the boring code they replace. Oracle makes those frameworks so there's a real conflict of interest in them owning Java.

Cable Co says No

The general public is so walled off behind NAT, firewalls, and throttles that peer-to-peer communications would be fragile at best. The Skype supernode collapse was a good example.

This will all be fixed when competition between ISPs forces them to upgrade to IPv6 and allow the free flow of traffic. Any day now. Holding breath...

What's Oracle got up its sleeve?

Kevin McMurtrie

Hybrid

If the faster bit is SSD, the cheaper bit could simply be hard disks that spin slower, use less power, and have a higher density. I'd imagine it would be targeted to online services where the active data doesn't fit in Oracle's RAM cache but could fit in a few TB of SSD cache. The SSD would cost a lot, but not nearly as much as building the entire RAID from top-performing spinning disks.
