Comment No mention on NHK in Japan? (Score 1) 50

Just watching another news program and sort of disappointed it didn't get any coverage. The last few days had quite a bit of coverage about a new and quite small orbit-capable rocket, though the payload is quite small, on the order of 3 kg. There were several stories before the launch, and then some reports of the failure. (The early reports suggest a telemetry failure?)

Comment lying (Score 1) 167

I can't use profanity because my Facebook Friends are actual friends, acquaintances, family and stuff.

actual friends, family and stuff are also the people of whom you might not want to hurt feelings and opt to not outright tell everything which goes through your head
("you're ugly as shit", "you clothes/car/whatever is crap", "your idea is stupid and you should be burned in public in the town square for that", etc.)
but where you would restrain yourself
("you've got personality", "well, it's original and has got some charm", "it's a surprising idea").

So again they are the people to which you would "lie" (in a fashion. You're not actively trying to outright deceive them, just not transmitting 100% of the information) which is what this study tries to point out.

Comment No award for you (Score 1) 345

Let's be serious here. Three hours? The last long drive I did, my only stops were fuel stops. I was going for about six hours without stopping for anything, and only stopping for fuel and to pee. Stopping every two hours would be incredibly frustrating.

If you want to kill yourself in a car-crash because of attention deficit due to over-tiredness because your concept of a well rested and alert driver is "15 minutes tank-and-pee pause between every block of 6 hours of non-stop driving", be my guest.

But remember :

  • To be eligible for a Darwin Award, you need to only take yourself by your own stupidity. You shouldn't maim any innocent by-stander.
  • So please try to crash into a tree next time you fail because of microsleep, instead of crashing into my car. (But I suspect that we leave on different continents and that I can be thankful for the Atlantic pond to prevent our paths to cross).

More seriously :

  • What you describe (blocks of 6 hours of driving, separated by 15 minutes breaks) is outright illegal for professional drivers here around.
    It is 6 hours of driving *total* (excluding the breaks) per work day, then a minimum of 4 hours of rest before the next work day[1]
    (I.e.: on a continuous 18 hours bus trips, there should be 2 drivers switching seats)
  • There is ton of research pointing that tiredness gets very important very quickly. By 6 hours of non-stop driving you might as well be drunk or high as a kite. (There are even studies that try to map level of tiredness and b.a.l. based on similar reduction of alertness/reactivity).
  • Humans are extremely bad at self-evaluating exhaustion, specially in simple monotonous repetitive task that aren't physically exhausting. If you indeed drive in batches of 6 hours, you certainly have had microsleep episodes.
  • But - at least until now - these eposides both :
    • went unnoticed (that's actually pretty normal. You can't consciously notice that you are unconscious)
    • and by sheer luck (or thanks to anti-collision technology available in your car[2]) nothing major did ever happen.
  • In other words, current research points out that No, you are not a good driver as you might think. You're instead a lucky driver (and/or have a good car).

For all purpose, there isn't a big use case for cars that can drive more 600 km in one go.
Car *can* do, for the convenience of not needing to tank at each stop.
But they are not that much necessary - cause the puny human meat at the driver seat can't reliabily drive safely for extended periods of time.
You either need several puny humans to cycle between. Or you need much longer breaks within these 600km that the car can handle.

So :

  • cars like 60-to-100kWh Tesla, 44kWh model Zoes, 60kWh Opel Ampera/Chevrolet Bolt, etc. with their 250 to 500 km autonomy
  • combined with the ever growing network of fast charger
  • (and a big thank to Mennekes and Chademo for having a small set of widespread fast car-charging standards)

are already pretty much enough for most car needs with maybe only a few key exceptions (i.e.: alterning drivers for extremely long trip or people who are really a lot into the "suicide by tree" fad)

This is even more noticeable in the (slightly more) densely populate Europe which is a bit more conscious about its security (higher risk to crash into meaty humans instead of trees when there are more of them around instead of a dust desert), where big centers are close by (very often your travel destination is within a 300km drive anyway), and with a good electrical network with quite some power available (thanks to alpine dams, nukes, or renewable - depending on countries).

Of course, you could argue that all these are example of Nanny-state in our "evil-communist" socialist-leaning European countries, that stay in the way of good drivers and that everyone should be responsible for themselves on the road, and that I'm just brain washed by state propaganda and by government-sponsored bogus research.

[1] I actually have a military professional driving license. These are the actual number required by local law.

What complete and utter shite are you spewing?

Actual experience of my wife with H1-B employees (including the "chagrined when discovering the forged credentials" case).

When getting your H1-B you need to provide documentation from your university as proof of your degree. The university must be on a list recognized by the US government. They validate the information with the university rather than just rubberstamping it.

Any of the following would explain that:
  - The agency faked the references, too.
  - The government didn't do the validation you claim it does in every case.
  - The government doesn't do the validation you claim and you're talking through your hat.

Please put your flamage aside for the moment and give us a reference to documentation showing that the government officials actually check credentials, rather than doing spot-checks or taking the applicant's word for them (or bribes).

Modulation designators that state the payload type don't make much sense with digital data transports. You can do digital TV or anything else with 4 MHz bandwidth. Cellular doesn't make much sense unless they have a really long hover time and drone life, in which case it could be a pop-up base station.

Comment Credit card chargeback. (Score 3, Informative) 74

Go to your card provider (Visa/MC/Discover/Amex) and tell them to remove the charge because the service was not rendered and/or the charge was improper.

They will.

Once AT&T starts getting a lot of chargebacks, they will do something about it.

I had this sort of thing happen do me years back in NYC with Verizon. I called to cancel, was given a confirmation # and everything, and was still billed again the next month. When called again, furious, the manager I was escalated to said that they could not offer a refund because they did not have that policy. I said I don't care about policy, give me a refund, and he said there was literally no way for him to do that in the system and suggested (of course) that I accept the service for a month, since I'd already paid for it, and then if I didn't want it next month, I could call and cancel [n.b. AGAIN] then.

I hung up on him, dialed Visa, and had them charge it back. Of course THAT got Verizon's attention and a day or two later I was called by retention or some similar department to offer me a discount if I would stay on, along with a lot of apology garbage.

I told them I'd rather eat a bug.

Comment Renault Zoe (Score 1) 345

What range do you think EVs have on a single charge, anyway?

Between 100km and 150km per 20kWh worth of battery charge.
Exact mileage depends on car model.
(e.g.: Tesla use lighter than average material and are designed from the ground up for longer ranges.
Other cars are simply "an electric motor replacing the ICE under the bonnet and batteries bolted wherever there's free place" quick conversion like the VW e-Golf and VW e-Up that VW hastily released in the wake of the diesel scandal, and might have lower mileages).
Also depends on the driver (driving like an aggressive idiot at high speed on the highway, and you'll get a lower range than driving conservatively maybe a bit under the maximum speed limit).

I can drive upwards of 3 hours without a break.

Which is *definitely* not recommanded.
Current recommendations here around in continental Europe is a break each 1 or 2 hours max.
(e.g.: There are big public service campaigns to advise drivers to have at least a quick "turbo-nap" every once in a while when driving long distance)

But let's make the assumption that you are 2 drivers sharing the load, and that you'll switch midway (without charging the car, nor making any break longer than required to change seat - no the best experience, but hey).

With an average-priced EV, that's not even near possible.

Renault Zoe are currently the cheapest e-cars with a decent battery.
(You can even get them for the price of an average priced ICE-car if you decide to rent the battery instead of buying it).
(They are definitely after the same market as Tesla's upcoming model 3, except that Zoes have been on the street for quite some time, and Renault chose the opposite progression from Tesla, release progressively longer range vehicle while staying affordable - instead of long range vehicles while progressively releasing cheaper models)

The latest model has upgraded the battery to 45kWh, which should give you between 200km and 300km of range. (depending on the speed/aggressiveness of driving 130km vs 100km on highway vs. 80km on streets between cities).

That's definitely in near the 3 hours of your example (and by now, both drivers of our assumption should get a nap, or at least make a long break - enough to put quite some additionnal range back into the battery using standard 50kW chargers)
For a car that cost in the general ballpark figure of ~30k USD (not some 100k+ USD Tesla Model S super car).

And all of the above aren't made up numbers, but my actual experience with Zoes.
They are available at the local car-sharing company (though not the more recent 45kWh battery), and I've already driven quite a lot of trip with them.
I can easy get 100km when I drive aggressively or 150km when much more conservative.

The current drawback I see, is that Renault doesn't have collision avoidances option available on their smaller cars like the Zoe.
(unlike VW where - like lots of european constructors - for the last several years even the lowest entry-level model like Up comes with a LIDAR [a.k.a. "City Safety"] in standard configurations,
or unlike all the noise that Tesla is making around their "Autopilot" since a couple of years ago).

Comment Needed environment for me is 7, 7pro, 8, 8.1 only (Score 1) 430

Meanwhile Win 3.11... Is still running fine on test equipment. The manufacturer says do not upgrade to any other version of Windows.

I have a gang-programming-and-testing production tool from one of the top three (or so) manufacturers of BLE systems-on-a-chip. Our startup needs this (or a suitable alternative) to go into volume production of our initial products.

It comes with an application - in source in a build environment. This allows it to be customized, to add tests for the peripherals added to make the final assembly, and to integrate into production processes and databases.

But the build environment is only supported in Windows 7, 7 Pro, 8, and 8.1, using Visual Studio 2012. The executables and DLLs produced run only on those or XP.

The executable/DLLs use .NET, too, and the way they use it breaks the GUI under wine, even with genuine Microsoft .NET installed. They run correctly, but the status display is corrupted in a way that makes it unusable. So at the production site it needs to run on genuine Windows at one of those levels. B-b

As of the last time I checked (a couple months ago), the manufacturer is unwilling to port to another OS or version - even though all of them (except maybe 7 Pro) have been end-of-lifed by Microsoft.

Comment Yup, GNU/NT-Kernel (Score 3, Interesting) 182

If I understand it right, it's a GNU/Linux distro without a Linux kernel on top of a compatibility layer on Windows, right?

Yup, mostly(*).

So "GNU/Windows NT Kernel" is better than "Linux" - That actually one of the rare few occastion a typical "GNU/Linux" distro gets used without the Linux kernel part.

But because "Linux" has brand recognition, it's still used.


(*): there's no separate compatibility layer (unlike things like Cygwin which are a user-mode compatibility layer that translates POSIX API-calls into Win32 calls - and thus enables soure compatibility).
The NT-Kernel has a bizare peculiarity : it can export several different ABI's to usermode software - it has different "personnalities".
- Win32 is just *one* of the set of ABI available.
- A long time ago, that made it possible to run OS/2 software on Windows NT.
- A little bit less longer time ago, Windows NT also had a "Unix" personality.
- Now WSL is actually the NT kernel exhibiting a small subset of the ABI featured by the linux kernel - about the bare minimum to get a few basic user-mode software (e,.g.: the "GNU" part of "GNU/Linux") run unmodified.

These are straight ABI available from the NT-Kernel, not a mere Linux-to-Win32 API conversion like Cygwin.

- Among other defaults Win32 has a poor multi-processing (forking is expensive). Cygwin application have to rely on that poorer cousin in order to provide multi-processing to POSIX.
- The recent kernels of Windows NT intoduced pico-thread which are very cheap, weren't available in the Win32 API back when introduced, but where exposed through the "Linux-lite" API that is WSL in order to make a usefull multiprocessing.

On the other hand WSL is far from complete. There is tons of stuff that you can do on your GNU/Linux that you can't do with WSL (e.g.: filesystem drivers)
