CloudFlare to launch its own 'high security' web domain registrar

Bullet proof

May domain owners remain completely anonymous for a certain fee? You know, to dissuade individuals from filing a lawsuit. Or maybe the operations of the domain are illegal in some/all countries and the operator does not want to worry about international prosecution. Such a feature would integrate well with other CloudFlare services.

DTIM and Beacon intervals

WiFi already has a system for delayed processing of unicast (beacon TIM) and multicast (DTIM) data so that devices may sleep. A better request would be to device makers (Apple) to address bugs that require people to set extremely short intervals.

'Millions' of routers open to absurdly outdated NetUSB hijack

Re: Everyone wants "cheap"

Cheap isn't the problem. Expensive "Small Business" networking gear is the worst possible mix of half-assed features, blatant flaws, and no hope for upgrades. The problem is that it's not easy to get a refund for severe software defects. They're usually treated as "dissatisfied customer" returns with a 14 day period. Require security vulnerabilities to be in the same category as manufacturing defects and then deadbeats like Netgear and whatever "Linksys" is will vanish overnight.

Nuke icon because I have, on multiple occasions, bought and returned every single router at an electronics store.

Google crafts custom networking CPU with parallel computing links

Re: A bit like a ... 386?

If it's a very simple architecture with no legacy baggage, they're probably tiny enough to be crammed into computers by the thousands. Most well defined tasks with well defined inputs can be implemented within a crude instruction set. Coding becomes difficult but hardware costs more than people when you're approaching a global scale of data processing. Google also believes (sometimes incorrectly) that they can do anything better than the rest of the world so it's no surprise that they'd keep building more hardware for themselves.

Re: big fuss over nothing

T-Mo announced it as an option and invited people to turn it on. Of course I deleted the e-mail. Then they silently turned it on for everyone and broke high quality video playback. That second part is quite worthy of raising a fuss. Everybody was suddenly throttled and it wasn't clear why. Anyone who had set their streaming preference to HD, or watched a video only offered in HD, got nothing. Today they announced dial codes to control the feature but they still haven't announced that it's an opt-out feature.

Perforce boss: ‘I’m just the cook’, flips firm to private equity

Re: Staying free?

Perforce Enterprise is cheaper than anyone expects but there's a stigma about it costing money. I'd pay for my own license if given the chance to use it. I'm sure I'll get downvoted for saying this, but Git is absolutely awful for enterprise use. Even the slightest variation from the perfect workflow is walking through a minefield of dangerous, convoluted, and poorly documented features. If employees are spending 1 hour a week on Git, the lost productivity makes it 10 times more expensive than Perforce.

Japanese wireless boffins demo 56Gbps fibre replacement*

Kevin McMurtrie

Halfway there

This technologically very cool but those frequencies are too easily blocked to be useful without other changes. We'd be reaching for the sky to get our phone's data working. A combination of 100Gbps wireless and fiber in a small chipset could be a winner. This would enable dense arrays of short-range transceivers to be mounted on existing infrastructure. It would have to be very small, like 4cm cubed, and use daisy chain cabling thinner than a few mm. Anyone who's seen a large grid of 5GHz WiFi transceivers on Cat 6 knows that high performance wireless tech needs to get a LOT smaller to be practical.

Another too late

The list of LTE bands is quite short for a new phone. I looked at buying an OPPO or OPO but it's missing bands that are useful in the US and bands needed while traveling. 2G and 3G are being taken out of service in many areas so there may not be anything to fall back to.

Boffins switch on pinchfist incandescent bulb

Kevin McMurtrie

Been there

This was done before with double walled xenon halogen bulbs. The inner bulb used high pressure xenon and a bit of halogen that let the filament run very hot without evaporating. The outer bulb had a vacuum for insulation. When you see a 1990s car with a dimly glowing cracked headlamp, it's one of those with a crack in the outer bulb.

Stanford boffins snuff out li-ion batt blaze risk

Kevin McMurtrie
Bronze badge

Fixing what?

Battery overloading was solved a long time ago. There's a limiter PCB on battery packs to ensure that voltage, current, and temperature stay within short-term safe operating limits. If that fails, there's a polyfuse (conductor particles in an expanding polymer) to break the connection while the combination of heat and current is too high. The final and non-reversible protection is a porous boundary layer in the battery that is supposed to convert to a solid barrier when heated.

LiPo batteries still catch fire for other reasons. The voltage needed to reach 100% charge becomes fatal after being applied for a few extra hours. Contaminants and physical damage can burn up the battery from the inside. The battery contains enough energy to melt itself free of lightweight protection schemes like aluminum foil wraps and laptop cases.

Was Android moving to OpenJDK really a Google gift to devs?

Kevin McMurtrie
Bronze badge

I still see a lot of Java in the AOSP projects. With a proper JIT (not Google's), the memory to performance ratio can be dynamically tuned for each code method. The other big feature that isn't talked about much is that the JIT not only converts generic code to a specific instruction set, but it also generates instructions that work around hardware bugs in a specific version of the chipset. It's exactly what's needed when 5 years worth of phones are running a dozen chipsets that are each upgraded every few months.

The downside of syncing up to OpenJDK is that it may be difficult to prevent developers from draining the battery. Poorly performing "Reflection" and anonymous adapter classes are the secret sauce behind many popular frameworks. Lambdas are the new lightweight solution to anonymous classes but the implementations churn through a lot of temporary memory.

Re: Quicktime

It defines a crappy file format too that, unfortunately, seeded the MPEG 4 container standard. QuickTime X was supposed to fix all of that but it seems that it was never finished much beyond AAC and one of the worst implementations of the H.264 codec. Upgrades since then have been in the form of poorly distributed codec plugins.

iOS 9 kludged our iPhones, now give us money, claims new lawsuit

Re: Honest question here

A search of the intertubes says that you can not downgrade. The iPhone bootloader is locked and the iOS9 version does not recognize the iOS8 digital signature.

This is why I only buy phones with a bootloader that can be unlocked. Manucatureres don't like maintaing old phones when there's money in new phones. Once the phone is about a year old, third party ROMs start working better than manufacturer ROMs.

"thousands of picojoules for each bit"

Yea! Let picojoules per bit be the next meaningless benchmark race! Since joules and bandwidth both have a base interval of one second, the math comes out to simply (Watts / Bit rate) / 0.000000000001.

Yikes, my home Internet uses over half a million picojoules per bit! I'm going to start calling around to see who can do better than that.

We have this list of e-mails worth billions

What does any dot-com do when collection agencies are checking resale values of the office furniture? Illegal spamming, of course, but with a dumb trick to make it seem legal. Create a new customer marketing preference, default it to "spam constantly", and open the floodgates. Recently I've seen these Oracle/Verizon addresses spewing:

mail01.info.mouser.com (142.0.163.126)

mail02.get.comcastbiz.com (204.92.21.44)

I guess Oracle is in worse shape than thought if this is their new plan for short-term revenue.

Nice buildings, good location

There's probably not enough to salvage at Yahoo. Their accounts are constantly getting hijacked, they stopped having unique products years ago, the codebase is layers of legacy patches, the portal designs spew too many trashy ads to be functional, and a Yahoo e-mail address is a really good spam indicator. Yahoo could vanish and the world would get over it in a couple of days. The biggest losers would "customer loyalty" companies having millions of throw-away yahoo.com e-mail addresses that can no longer be claimed to be live customers.

Typo in case-sensitive variable name cooked Google's cloud

Kevin McMurtrie
Bronze badge

It's not an equality test that is involved. Headers, configuration parameters, and interpreter variable names are looked up by with a fast indexing scheme, like a hash. For that to work, all parameters must always be case normalized before use. It seems trivial but it can cause an even more trivial key-value lookup to take 1000 times longer.

No root for you! Google slams door on Symantec certs

Kevin McMurtrie

Re: What's the problem?

Follow the link. Symantec generates fake certificates for testing, development, and other "non-public" uses. Those leaked once and Google is worried that they will leak again. If I read between the lines, I think that Google suspects Symantec of being forced to create them for covert spying. That would put Google's hard-earned hoard of extremely personal and extremely valuable data at risk.
