UHD Spec Stomps on Current Blu-ray Spec, But Will Consumers Notice?

hackertourist depends on features (293 comments)

Will the standard contain provisions for unskippable items? Then I won't buy an UHD player.

hackertourist Re:Better Link (182 comments)

Please be aware that WhatsApp Plus contains source code which WhatsApp cannot guarantee as safe and that your private information is potentially being passed to 3rd parties without your knowledge or authorization

That's rich coming from them.

User Plea Means EISA Support Not Removed From Linux

hackertourist Re:Crusty Hardware (187 comments)

Meanwhile in that era, us Apple users plugged in & played with our NuBus cards without ever having to fiddle with IRQs. Doing things right the first time saved us a lot of aggravation.

Fake Engine Noise Is the Auto Industry's Dirty Little Secret

hackertourist Not a secret (790 comments)

TFTitle is stupid: none of this is a secret, every car manufacturer that does this readily admits it to the motoring press.
I, for one want my car to be as quiet as possible so I'd want the option to disable it. Or I can do what I've done with my current car: replace the stereo.

The Tech Industry's Legacy: Creating Disposable Employees

hackertourist Re:Time for a UNION! (263 comments)

That's a solution only if you accept the drawbacks of being a contractor. Suddenly you have to do acquisition, you're a business so your taxes get 10x more complicated (e.g. VAT), etc.

We're seeing some industries moving towards an all-contractor model over here (.nl). Postal delivery and the building trade for instance. Some contractors do well for themselves, but there's a large number of them subsisting below the poverty line. As a contractor they're no longer protected by employment laws so they get screwed over no end. Especially in the building slump of the past few years people were agreeing to work for a pittance, not realizing the consequences in time. And if they don't get a contract, they're business owners so not eligible for unemployment benefits either. Meanwhile the contract prices are under pressure as workers from low-wage countries migrate here and accept conditions that result in a wage that is livable in their home country, but not here.
This is a gigantic poverty trap, and an end run around employment law and the unions by building companies. IMO a service/contract culture is not something we should wish for.

Librem: a Laptop Custom-Made For Free/Libre Software

hackertourist Yes, but (227 comments)

does it run OS X?

Seriously: this is a nice-looking laptop, and one I'd prefer to the current Macbook Pro line due to those not having user-upgradeable HD and RAM.

Microsoft Researchers Use Light Beams To Charge Smartphones

hackertourist Not as efficient: TFS is wrong (63 comments)

TFA says: "Using a light beam to charge a smartphone could be as quick as many wired chargers, the researchers found, depending on the size of the PV panel."

Efficiency is going to depend on the efficiency of the PV panel in the phone, but at 20% it's a long way off from the efficiency of a wired charger.

The lengths to which people will go to avoid plugging in a wire still amaze me.

SpaceX Landing Attempt Video Released

hackertourist Re:Wait a minute (248 comments)

The point of an open system was not to dump the hydraulic fluid overboard after use, but to not need a pump that can return and reuse the fluid (and a system to power the pump, and fuel for that etc).

SpaceX Landing Attempt Video Released

hackertourist Re:Wait a minute (248 comments)

The main hydraulic system on the F9 (for gimbaling the engine nozzles) uses RP-1 (i.e. rocket fuel) as its hydraulic fluid. Spent fluid from that system goes into the fuel tank.
The fins are driven by a separate system at the top of the stage, if they pumped the spent RP-1 overboard you'd have flammable liquids running down the stage, I'm pretty sure they don't want to do that. Returning the RP-1 to the fuel tank is unlikely (needs an insulated pipe around the outside, next to the cold LOX tank). So probably a separate waste tank near the fins.

Belgian Raid Kills 2, Said To Avert "Major Terrorist Attacks"

hackertourist Re:How could this all happen? (257 comments)

Could you please let me know which Govt Department I go to in France to apply for the location I am allowed to live in?
I seem to be having trouble finding it - hell - last time I was there I just lived where I damn well wanted to and could afford..

The word 'afford' is key here. If all you can afford is the lowest-rent housing, then that's where you end up. That's how many large European cities ended up with immigrant ghettos.

Your High School Wants You To Install Snapchat

Dictionary entry or not, lede is a recent 'invention' by people who should know better than to make up new words when the old one was clear and unambiguous. See also "when it bleeds, it leads".

Chinese Spacecraft Enters Orbit Around the Moon

hackertourist Re:Great to see (152 comments)

You're confusing technology with "currently in production". Several companies in the US posess all of the technology needed to put humans in space. They just haven't produced and flown spacecraft yet.
It is a political issue, pure and simple. The transition between the Shuttle and new manned systems was planned badly, allowing a several-year capability gap.

China's Engineering Mega-Projects Dwarf the Great Wall

hackertourist Re:Infrastructure (206 comments)

The main reason they can build so quickly is that the Chinese government routinely kicks huge numbers of its citizens out of the areas where they want to build their infrastructure. That's not something to envy.

The Strange Story of the First Quantum Art Exhibition In Space

hackertourist Re:Um, what? (69 comments)

Not just eventually, all at once. We just have no way to extract all that superimposed information.

I half expect the author to eventually come out and say he just made it all up to find out how much nonsense he could get away with by labeling it art.

Chevrolet Unveils 200-Mile Bolt EV At Detroit Auto Show

hackertourist Re: Only 30 Grand? (426 comments)

Part of the problem in this discussion is that your UK gallons are larger

No. I looked up l/100 km and converted that to American gallons.

The iQ at 37 mpg? Then there's something seriously screwy going on with those numbers, because RW it gets closer to 55. You'd have to drive it like a buffoon to get anywhere near 37 mpg.
The Mirage RW numbers you quote have sample sizes of 2 and 5 respectively so yes, they are suspect. The numbers I quoted have much larger sample sizes so they're bound to be more accurate.

Chevrolet Unveils 200-Mile Bolt EV At Detroit Auto Show

hackertourist Re: Only 30 Grand? (426 comments)

I chose examples that exclude legislation as the reason lightweight cars aren't built any more. So the reason lightweight cars aren't built any more must be something else. The American fondness for huge cars may have something to do with it.

In Europe, there's an entire class of cars smaller than the Mirage and Fiesta. The VW Up (47 mpg), Suzuki Alto (54 mpg), Toyota Aygo (56 mpg) to name a few (and that's real-world fuel consumption, not a theoretical rating).
This site has RW usage of the Metro at closer to 40 than 47.

The XL1 is in production, by the way. Expensive, but definitely not a concept any more.

Chevrolet Unveils 200-Mile Bolt EV At Detroit Auto Show

hackertourist Re: Only 30 Grand? (426 comments)

There's no legitimate reason why cheap, lightweight cars like the Honda CRX (better fuel economy than a modern Prius... in 1988!) are effectively no longer allowed to be made.

Stricter safety regulations mean some weight gain has been inevitable. As for the rest, I remember how austere those lightweight cars used to be. Everything manually-operated, no air con, no soundproofing, minimal dashboard (no cupholders). The reason almost nobody builds cars like that anymore is almost nobody buys cars like that anymore.

Lightweight cars are still possible. Lotus and Smart for example. VW XL1. Austere cars are still available too (in Europe at least, IDK about the States) (a recent Citroen, Dacia).

Power grid demand matching using flywheels

hackertourist hackertourist writes  |  more than 3 years ago

hackertourist writes "A novel type of electricity storage was recently added to the New York power grid. The unit, supplied by Beacon Power uses flywheels to store energy. The unit is intended to replace gas turbines in supplying short-term peaks in power demand (also known as frequency regulation). It can supply up to 20 MW, using 200 flywheels."
