I'm not sure how easy it would be to normalize different vehicle suspensions. You'd have to have some kind of test road with a known surface quality that the car could be driven on the calibrate the app to the car.

I'd like to see municipal vehicles and maybe buses equipped with scanners that could map the actual road surface.

to be able to watch Eastenders in Ultra HD...

To the Beeb's credit though, the Sky at Night in UHD would definitely be a lot more interesting, surely. But out of thousands of mediocre shows and movies released year after year after year, is it worth buying a new tv to marvel at a dozen really good programs? Somehow this don't seem to be a good value proposition.

Kernel bypass plus zero copy are, of course, old-hat. Worked on such stuff at Lightfleet, back when it did this stuff called work. Infiniband and the RDMA Consortium had been working on it for longer yet.

What sort of performance increase can you achieve?

Well, Ethernet latencies tend to run into milliseconds for just the stack. Tens, if not hundreds, of milliseconds for anything real. Infiniband can achieve eight microsecond latencies. SPI can get down to two milliseconds.

So you can certainly achieve the sorts of latency improvements quoted. It's hard work, especially when operating purely in software, but it can actually be done. It's about bloody time, too. This stuff should have been standard in 2005, not 2015! Bloody slowpokes. Back in my day, we had to shovel our own packets! In the snow! Uphill! Both ways!


First Successful Collision Attack On the SHA-1 Hashing Algorithm (google.com) 77

Artem Tashkinov writes: Researchers from Dutch and Singapore universities have successfully carried out an initial attack on the SHA-1 hashing algorithm by finding a collision at the SHA1 compression function. They describe their work in the paper "Freestart collision for full SHA-1". The work paves the way for full SHA-1 collision attacks, and the researchers estimate that such attacks will become reality at the end of 2015. They also created a dedicated web site humorously called The SHAppening.

Perhaps the call to deprecate the SHA-1 standard in 2017 in major web browsers seems belated and this event has to be accelerated.

Comment Re:Should hit my monthly cap in 1/3 of a second (Score 1) 54

Not exactly, its GigaBytes per month and GigaBits of speed.

You'll have 8 times as long until you hit the plan cap, so 8/3 of a second or 2 and 2/3 seconds.

Way better ;-)

Again I have to say, this is like having a Ferrari that you can only drive a few minutes a month.

The cognitive dissonance between freaking tiny bandwidth caps and huge speeds just keeps growing.

Comment Re:We are screwed. (Score 1) 54

the problem with wireless data isn't so much how slow it is; but how costly it is(in part because of scarcity, which more efficient RF technology might actually alleviate, the 'because we can' part is a separate issue)

I'd like to know the difference between the high costs due to real scarcity and the high costs due to profit-taking.

I'd love to see a heat map of cell sites based on RF congestion and backhaul congestion to get an idea if the limits being imposed are really about site limits or mostly about extracting maximum profit.

Comment Fuck off, I decide what's fair (Score 5, Insightful) 302

Many websites only exist because of user generated content (like /.).

Don't impose your idea of what's fair to the content I provide for your site.

Web sites had the chance to go the NPR route and be low key about advertising but by and large they went the obnoxious way and embraced pop ups, pop unders, Flash, animation, and widespread invasive tracking.

Fuck that, I'm not participating in your scheme to get rich off my content, at least the part where I provide you with content and am then expected to be shouted at by ads and tracked. That's not even remotely fair.


SIgn Of the Times: Calif. Privacy Protections Signed Into Law 41

The EFF reports a spot of bright news from California: Governor Jerry Brown today signed into law the California Electronic Communications Privacy Act. CalECPA, says the organization, "protects Californians by requiring a warrant for digital records, including emails and texts, as well as a user's geographical location. These protections apply not only to your devices, but to online services that store your data. Only two other states have so far offered these protections: Maine and Utah." The ACLU provides a fact sheet (PDF) about what the bill entails, which says: SB 178 will ensure that, in most cases, the police must obtain a warrant from a judge before accessing a person's private information, including data from personal electronic devices, email, digital documents, text messages, and location information. The bill also includes thoughtful exceptions to ensure that law enforcement can continue to effectively and efficiently protect public safety in emergency situations. Notice and enforcement provisions in the bill provide proper transparency and judicial oversight to ensure that the law is followed.

And the simplicity... well they did just come out with the SCv2000 which is all wizard-driven and about as dead simple to set up as the EQL. I predict we'll see that same level of simplicity making its way into the higher tier products pretty soon.

That would sure be nice. I like the statistics and most of the features of EM, but their I/O configuration is lunacy, up to and including the required license for virtual ports. All of that feels like a networking configuration system that was solved (and better) elsewhere. I'd like to think they don't make it horrifically complicated just to drive reseller/support revenue and that there's something deep inside that makes it worthwhile, but I find it hard to believe.

The auto tiering if configured correctly can certainly make for an interesting performance story. Put SLC at the top where you want fast writes and allow it to trickle down to MLC and/or TLC... just like 15K->10K->7K. There's a question mark over whether current controllers can really take advantage of the potential performance in this kind of setup, but we're seeing controller performance increasing over generations anyway.

IMHO, new flash technologies like Intel/Micron 3D-Xpoint will moot the need to tier between older generation flash technologies. I also suspect that for all but a few workloads MLC is just so much faster that it won't matter at the customer side. Any performance increase is probably offset by the need for heavier weight controllers needed to manage tiering and data page management.

And as you suggest, interconnects would remain a limiting factor -- how many 24 drive MLC shelves until you saturate even a SAS-12 bus?

Even in networking... they've shit-canned the atrocious Powerconnect line of switches (that some people loved) and replaced with a whole new line of switching from low end to high.

I think the N series is pretty good. I don't see much uptake of Force10 since N series came out and the price/performance/features of the 10 gig N series are pretty good. I'd love for someone to give me a couple of the 10 gig models...
