Google Offers a Million Bucks For a Better Inverter

LinuxIsGarbage Re:110 or 240v (255 comments)

Yes, because the US cheats and uses 220 split-phase to provide 110 power. Most everywhere else that needs high power uses 3-phase, as it's smoother, easier to produce and rectify, and just as safe to transmit.

3 phase makes electric motors more efficient, and that's it. Technically, you could have as many phases as you could imagine having... each making the motor a tad more efficient. But they are not "smoother" and don't improve transmission.

3-Phase AC produces a smoother (considerably less ripple) DC current pattern when rectified than single or split-phase AC.

I've seen 3 phase 700V+ DC drives at over 1000kW that are very harmonic rich. Over 100% THD. Not smooth AT ALL.

Google Offers a Million Bucks For a Better Inverter

LinuxIsGarbage Re:110 or 240v (255 comments)

3 phase requires the return by code. Technically however, you are correct. That's just for safety and I often question if it makes any sense myself.

In an industrial settings I deal with a lot of loads that are three phase L1, L2, L3 + safety ground only (shield on cable, chassis on machine). No Neutral. Even 4160V loads. Unbalanced loads are brought back through L1, L2, L3.

Buying New Commercial IT Hardware Isn't Always Worthwhile (Video)

LinuxIsGarbage Re:Nail in the coffin... (92 comments)

Oh, great, it's hard enough to replace obsolete equipment as it is. Once management sees this, they'll wonder why we can't keep that old Dell server going a few more years - after all, other companies are buying the same server for this guy. IT will never get another upgrade approved ever again if this gets out. Forget the cost savings of lower-power equipment, and the massive throughput increases in newer drives.

Lucky you getting to keep that old Dell server... We have to keep that old 1983 PDP-11 going.

Wait, there are updates for Windows?

Uh-oh.

That's why I just use Windows XP. I haven't been bugged for updates in a while.

Nearly 25 Years Ago, IBM Helped Save Macintosh

LinuxIsGarbage Re:PPC macs were awful (236 comments)

When Macs didnt just needed a restart every 24 hours (like windows did) but would outright ruin there system install every other week?

You MUST be confusing MacOS and Windows.

I have been using Macs since they were called Lisas (yeah, yeah, I know. Different OS (sort of)), and using Windows since at least version 3.1, and in all those years, I have only had to resort to an OS Reinstall ONCE on a Mac (68k or PPC). I cannot even begin to count the times I had to do a reinstall on Windows. That stuff didn't even BEGIN to abate until Windows 2000.

As far as having to restart, both OSes had their fair share of memory leaks. But when it comes to "outright ruin there[sic] system install[ation]", there is simply no comparison.

I've very rarely had to *reinstall* any OS (none I can think of except a hard drive failure), but from a Stability point of view, Mac OS was junk until OSX, Windows was complete feces until W95, and Junk until W2000. This is from an end user point of view. NT was relative stable before 2000, but it wasn't end user friendly.

Nearly 25 Years Ago, IBM Helped Save Macintosh

LinuxIsGarbage Re:Counterbet (236 comments)

I bet Google DOES use some moderate amount of assembly. I once worked for an audio-recognition company and we did indeed use about 100 lines of x64 assembly to perform the inner loop, which was some complex audio signal processing routine. Similar to an FFT.

This was easily 10x faster than the C version, which we had for reference purposes, even when using the Intel compiker with all optimizations turned on.

So, just because you never saw a Tapir in your life, does not mean they can't exist because their dick is longer than you can imagine.

Maybe you shouldn't have been using an AMD processor:
(Intel has been slammed for their compiler creating code that directs non-Intel CPUs to completely unoptimized code, not taking advantage of SSE, etc, even when present in the non-Intel processor)

Leaked Build of Windows 9 Shows Start Menu Return

LinuxIsGarbage Re:Even versions of Windows the good ones? (346 comments)

You still fail to count properly because the non-NT kernels don't get counted into numbering.

NT->3.5 Because it looked like Windows 3.5

2K-> 4

XP->5

Vista->7

Windos 7 -> 7

Windows 8 -> 8

etc...

You Failed to count properly
NT 3.1
NT 3.5
NT 3.51
NT 4
NT 5.0 (Windows 2000)
NT 5.1 (WindowsXP)
NT 5.2 (Sever 2003 & XP 64)
NT 6.0 (Vista)
NT 6.1 (Seven)
NT 6.2 (Eight)

Microsoft Takes Down No-IP.com Domains

LinuxIsGarbage Re:No-IP should open up their nameservers (495 comments)

Turns out you can do this - their nameservers are at
nf1.no-ip.com
nf2.no-ip.com
nf3.no-ip.com
nf4.no-ip.com
nf5.no-ip.com

so

nslookup <your domain> nf1.no-ip.com

should give you your IP.

Mod parent and grandparent up!

Though I only got a response from nf3.no-ip.com.

How Apple Can Take Its Headphones To the Next Level

LinuxIsGarbage Re:sponsers (196 comments)

The only thing they ever had going for them was the unique 'b' shaped plastic. They are like a Louis Vuitton bag - not particularly functional or even attractive, but they cost a lot of money and celebutards like them so owning them buys you a tiny slice of that lifestyle.

While I don't own or like their headphones, the one other thing they have going for them is their success at ambush marketing. You see, as much as I hate their headphones, I hate the draconian advertising regulations that surround events like the Olympics and World Cup even more:

GM Names and Fires Engineers Involved In Faulty Ignition Switch

LinuxIsGarbage Re: No one will ever buy a GM product again (307 comments)

Because you lose power steering and braking, and you could lock the fucking steering column.

I can't say I've every owned a Toyota. But all of the cars that I've owned would not allow you to turn the key back to lock the steering wheel unless the car was in park or neutral.

All the cars I've owned wouldn't let you turn it to LOCK unless the car was in PARK, and could only start if it was in PARK or NEUTRAL.

Apple WWDC 2014: Tim Cook Unveils Yosemite

LinuxIsGarbage Re:Cherry Pick Stats (411 comments)

So they continue to pimp their new processor power in their phones (we have an A4 in this! That's right, A4, the chip we just invented! Oh wait, now we have the A5, now the A6, A7.) And then keep bogging it down with new features in iOS that really shouldn't make that much of a difference in performance, but grind old phones to a halt, and the difference is a wash comparing new iPhone +new iOS with old iPhone + old iOS?

Your premise that newer phones don't have features that make a difference is simply false.

Basic OS operations like switching apps, bog down compared to old versions. Why does the addition of fingerprint scanner, copy & paste, Siri, or removal of Skeuomorph suddenly require a significantly more powerful processor to check email, change applications, and text? I'm not saying new features introduced are without use, but there seems to be a disproportionate increase in CPU horsepower required.

Apple WWDC 2014: Tim Cook Unveils Yosemite

LinuxIsGarbage Re:Cherry Pick Stats (411 comments)

Apple stop providing older iPhones with OS updates when they are no longer powerful enough to support current OS release. They got it wrong once, by providing one two many OS updates for the iPhone 3G

So they continue to pimp their new processor power in their phones (we have an A4 in this! That's right, A4, the chip we just invented! Oh wait, now we have the A5, now the A6, A7.) And then keep bogging it down with new features in iOS that really shouldn't make that much of a difference in performance, but grind old phones to a halt, and the difference is a wash comparing new iPhone +new iOS with old iPhone + old iOS?

At least with Microsoft, while there is a system requirement increase from XP (12.5 years ago) to Vista (7 years ago). The system requirements have been flat for the past 7 years through Win7, 8, 8.1. Third party applications may have bloated in that time, but the base OS hasn't.

Ford's Bringing Adaptive Steering To the Masses

LinuxIsGarbage Re:Ghost in the machine (128 comments)

I remember reading about a vehicle made in Europe that was completely drive-by-wire with no mechanical linkages whatsoever. Of course, some vehicles had glitches, and when they did, there was nothing to do but hope the wreck didn't kill you.

You know how many criminal organizations would love to be able to use an assist motor to jam a steering wheel at will? With how interconnected vehicles are, it might just take a bluetooth hole to get on the CANBus, then go from there.

I wouldn't blame Ford specifically, but I do worry about things like GM's OnStar being a prime target for hackers. Get control of that, disable all GM cars, tout the accomplishment, and win immense street cred. Same with getting motor-assisted steering to start jerking the wheel at random to cause crashes, it would put an organization on the map and give them respect worldwide.

Car makers have been good, but in general, most companies feel that security has no ROI, so don't do much than lip service, and coupled with all the crap that can take over a vehicle's ECM [1], it can be concerning.

[1]: I was reading about a "tattle" device by one insurance company which apparently something over the OBD 2 connector, so if the device was removed, the vehicle wouldn't start. Is this real? Doubtful, but it is concerning.

Even without steer by wire, this can be accomplished with electric power steering. As an example, look at "Active Park Assist". The system will command the steering wheel to turn, pretty much to full lock, based on what the sensors see. I assume (maybe?) if it detects resistance on the steering wheel it won't over power it, but the technology is already there for the wheels to turn as the computer sees fit. Electronic Throttle Control means the gas pedal is really just a suggestion to the computer, and hybrids with regenerative braking, the brakes are (somewhat?) brake by wire.

Plus with push button start, to kill power for have to hold the power button for several seconds if you need an emergency shut down due to a malfunction. Cars are also moving to electronic parking brakes too.

The Energy Saved By Ditching DVDs Could Power 200,000 Homes

LinuxIsGarbage Re:Forget about traditional power savings... (339 comments)

Still not making any sense.

Talking about power factor maybe? If a motor is a slightly inductive load, you can put a capacitor to cancel out the inductance and bring power factor closer to unity. You will get the same "real power" out of the system, but your incoming current (amps) will be lower, because the phase angle will shift to be in line with voltage.

However residential customers are charged energy in kWh, so the "Amps", kVA, and power factor have no impact on the bill. Commercial / industrial can get hit with power factor penalties, as well as demand charges in kVA, so controlling power factor is important.

A bad power factor will impact the grid as a whole because the system has to be sized to handle the apparent power kVA, not just kW, increased current (even at a bad power factor) will increase I^2*R losses in the lines, but the mechanical energy in the generator makes real power.

Official MPG Figures Unrealistic, Says UK Auto Magazine

LinuxIsGarbage Re:Just like pints. (238 comments)

In Canada most places use lined glasses. The bartender is almost never going to actually look at the line, so you always get a bit extra. The point is that you know you're going to get a minimum amount of beer. Crappy bartender who pours a giant amount of head? No problem.

Fuel economy is the same thing. You can't tell if the inflated numbers for one car are more or less inflated than the numbers for another car. Not to mention you can't actually do any planning based on them.

At the microbrewery near me, the beer is sold in refillable 1.89L growlers. The proprietors always fill it as close to the top as possible, well in excess of 1.89L.

Official MPG Figures Unrealistic, Says UK Auto Magazine

LinuxIsGarbage Re:Lower? (238 comments)

Except the Yanks have smaller gallons 3.78 litres vs 4,54litres.

While a UK and Yank litre is the same 1000ml/cc

It's worse in Canada. Before Metrication, a gallon in Canada was the 4.54L Imperial gallon. And unless clarified, an unspecified gallon is still (supposed to be) assumed to be a Imperial Gallon. NRCan fuel consumption ratings are given in L/100lm, with ImpMPG still on the sticker for old farts. TV ads still push "MPG" ratings, and a lot of people still report their fuel economy in MPG even though distances aren't registered in miles, nor fuel sold in gallons (even young people who never bought gas in gallons!) It's even worse when they insist on using obsolete (for this country) units, yet don't even know which gallon they are using. In other cases they are too stupid to understand why Canadian MPG ratings are 20% larger than US MPG ratings.

Official MPG Figures Unrealistic, Says UK Auto Magazine

LinuxIsGarbage Re:taxes will lead to kludges (238 comments)

You're referring to an exceedingly small number of cases here. If you look at fuelly's numbers, only 55 out of 1879 Corollas tracked average more than 40 MPG (2.9%), while only 178 out of all 2930 Prii tracked get *less than* 40 MPG (6%). In the overwhelming majority of cases, the Prius gets better fuel efficiency than Corollas.

That, and the Prius' chief advantage is in city driving, which taxis operate in virtually exclusively. Since you're claiming Corollas beat them in their home environment, I call bullshit on your argument.

Not just city driving, but taxis do a lot more idling and waiting than a normal passenger car.

Stranger things have happened. Initially the city of Toronto failed to see as large of savings on Hybrid transit buses (seeing 10-20% vs. promised 20-30%), largely because they operated on suburban routes instead of stop and go urban routes.
