Stadium matches have their own security procedures and personnel. The French police are already spread thin with the current level of alert, and from the looks of it on TV they've even brought in military personnel to help augment the patrols. They simply do not want to have to devote additional resources to provide security for a protest, even if it was already scheduled and organized.

Atypical security personnel armed and trained to deal with militants tend not to mix well with an angry mob of protesters.

Comment Re:I Process Retail Returns Daily (Score 1) 60

In brick and mortar, top electronics returns are phone chargers with the wrong plug (Lightning instead of micro-usb or vice versa)

So not only does Apple flaunt the EU directive to standardize on micro-USB for phone charges, it shifts the cost of their non-compliance onto retail stores (and thus the rest of us) which have to deal with the returns?


C.H.I.P. vs Pi Zero: Which Sub-$10 Computer Is Better? ( 28

Make Magazine weighs in on a issue that's suddenly relevant in a world where less thn $10 can buy a new, (nominally) complete computer. Which one makes most sense? Both the $9 C.H.I.P and the newest, stripped-down Raspberry Pi model have plusses and minuses, but to make either one actually useful takes some additional hardware; at their low prices, it's not surprising that neither one comes with so much as a case. The two make different trade-offs, despite being just a few dollars apart in ticket price. C.H.I.P. comes with built-in storage that rPi lacks, for instance, but the newest Pi, like it's forebears, has built in HDMI output. Make's upshot? The cost of owning either a C.H.I.P. or a Pi is a bit more money than the retail cost of the boards. Peripherals such as a power cable, keyboard, mouse, and monitor are necessary to accomplish any computer task on either of the devices. But it turns out the $5 Raspberry Pi Zero costs significantly more to operate than the Next Thing Co. C.H.I.P.

Comment Re: Will Apple be able to spec/source a good OLED? (Score 2) 198

Color cast is entirely an Android problem. If Google would get off its butt and implement color management in Android, you could simply profile the screen and correct the color in software. That is in fact what Apple does with its phones, tablets, and laptops to eliminate color casts - they color calibrate each screen and implement the correction in software. It's got nothing to do with OLED - as long as red, green, and blue are being generated in sufficient quantities, you can have a perfectly color calibrated display assuming the software lets you actually calibrate it. And OLED generates gobs of red, green, and blue - enough to cover AdobeRGB color space and beyond. Most LCDs are limited to sRGB or less (they only use blue LEDs, and a phosphor which converts some of that blue light into yellow, with the yellow substituting for red+green).

Uneven backlighting and dark splotches a LCD problem. You try coming up with an arrangement of lights around a rectangular perimeter which provides even brightness across the entire surface area. LCDs use an complex arrangement of diffusers and light channels to try to spread the light around evenly. It is not precise at all, and very fragile. I had left my laptop closed on a table, and someone signed a piece of paper on top of it. Apparently they pressed down very hard, because the pressure from the pen was concentrated enough to deform the diffusers slightly, and that laptop screen developed a dark splotch right where the person signed.

Pixel noise is due to most LCD panels being 6-bit and using time-dithering (rapidly flickering it between two 6-bit color values) to achieve 8-bit color depth.

Color gradients I've seen on OLED screens, but it's not because of the OLED layer itself. It's something to do with the layers they put on top. It's greatly exaggerated if you look at the screen through polarized glasses. In theory OLEDs should look identical through a polarizer as without. But something they're doing with the layers above it (maybe the capacitive touch layer?) leaves stresses in the material which are obvious through a polarizer.

Burn-in is the one problem OLED does have. But I used my Galaxy S for 5 years without any significant burn-in.

Comment Re:Or just make the diesels hybrids (Score 1) 173

Hybrid electrics complement gasoline (petrol) better than diesel. You basically have three modes of vehicle operation you want to optimize. Acceleration from a start, highway cruise (only requires about 20-25 HP for most cars), and acceleration at speed for passing on the highway.

Gasoline engines hit their torque peak at mid-RPM (torque is basically how much energy is generated per cylinder firing), and their power peak at high RPM (horsepower is how much energy is generated per second, so torque * RPM). Typically you can design an engine for optimal efficiency at a single RPM, and so the sweet spot for a gasoline engine is mid-to-high RPM. In an ideal case, the engine would only ever operate at this sweet spot RPM. This means gasoline engines are great for passing at highway speeds, but suck for accelerating from a start (low RPM) and highway cruise (low power). Hybrids complement them exceptionally well because an electric motor's gobs of torque at 0 RPM helps with acceleration from a start. And the electric can handle highway cruise, with the gas engine starting up only occasionally (and running at its peak torque or HP range) to recharge the battery.

Diesel engines have a higher compression ratio so hit their torque peak at low-RPMs (in addition to being more efficient than gasoline). This makes them good for acceleration from a start, great for highway cruise (why most freight trucks are diesel), but they suck at accelerating at highway passing. A hybrid electric motor doesn't complement diesel as well - the main benefits it adds are things a diesel already has. The primary benefit would be regenerative braking, which is only about 30% efficient anyway. The tech which best complements a diesel is a turbo, which increases power output at higher RPMs.

If you did want to do something to a diesel to help with the start-stop cycle of city driving, some sort of mechanical flywheel arrangement to provide regenerative braking would probably be a lot cheaper and weigh a lot less than batteries and electric motors. And yes I know most locomotives are diesel electric. That makes complete sense when you force a tiny engine to pull a huge load. If you compare hp to weight ratios, a locomotive is roughly equivalent to a car with a 5 hp engine. If you wanted to make a car with a 20 hp diesel engine (so it could generate enough power to overcome aerodynamic drag at highway speeds), then coupling it with an electric motor is much more preferable to having a transmission with 25 gears.

This worked for Rob Ford (the druggie mayor of Toronto), and for two, maybe three, countries' rulers during WWII. So if you're a liar, don't stop lying! Redouble your efforts!

Comment C vs Pascal == Perl vs Python (Score 2, Interesting) 128

I remember despising C for its absurd syntax ("==", "!=" etc.).
I still do.

And I was the opposite, I despised the vebosity of pascal (begin/end/etc.) and it's tendency to try to hide some low level details on the grounds of making it easier to learn.
To each his own preferences.

That's a definitive proof that the Perl vs Python debate didn't actually need theese language and the whole concept dates back much further in computing history.

NO language needs a garbage collector, though an option to use one selectively would be nice.

Let's split the difference and say a language needs a garbage collector in its standard library that a programmer can choose to enable. C++ calls its reference-counting garbage collector std::shared_ptr.
