If you're 'senior' anything, you should have been around long enough to know that slashdot is not the place to ask a question, especially since its a question only you or someone who knows you REALLY well can answer.
My suggestion if you want some safety is to start with some introspection.
... because in the ridiculous example provided... they would certainly model it exactly after the EU law... because Muslim extremist countries are so thoughtful and considerate...
What they would do is 'Google is not allowed to exist anywhere in the world because they know of Charlie Hebdo'
Thats the point. Do you want this sort of thing happening where countries think they can tell other countries what to do, more so than already happens?
In reality, Google will just invade France with something as powerful as an Android device that just repeatedly plays 'capitulation' loudly and that would be the end of France complaining about 'Right to be Forgotten', which, by the way, is a stupid fucking law.
If people in France actually wanted to solve a problem, they'd remove the original source material, not just remove it from the index.
Its "our" fault that we don't magically undo a hundred thousand years of evolution and make every woman think being in tech is cool and make them want to do all the same things as men.
Its "our" fault that women and men are different.
Can someone please explain to me WHY WE HAVE TO HAVE EQUAL REPRESENTATION WHEN WOMEN AREN'T FRAKING INTERESTED IN THE JOB.
Oh wait... you know why? Because they can treat women to lower pay thanks to the required time off for most who want to have children not being able to dedicate every hour of the day to working their fingers to the bone like males can in most cases.
Yes, as a white male you are automatically a racist sexist homophobe on the verge of a hate crime. Its in our DNA apparently...
No, they don't, they just have a monopoly on getting caught often. We get caught less because we're better at it. It generally takes a traitor for us to get caught.
Yea, this is a great thing to teach our kids... do things you can't afford to do, and force someone else to pay for it or beg for money to do so.
WTF happened to running a balanced budget and setting a good example to our kids about living within their means, why the fuck are we teaching them in elementary school that you can depend on someone else to give you hand outs to survive.
Its no wonder the rest of the world likes to take our jobs, we're raising a bunch of dependent babies.
GIRLS DON'T FUCKING LIKE COMPUTER SCIENCE, GET THE FUCK OVER IT.
Its not because all men in it are assholes, its BECAUSE THEY DON'T FUCKING LIKE IT. They are wired differently than men, this is a KNOWN AND ACCEPTED FACT to anyone who doesn't have political correctness shoved so far up their ass they can taste it.
Women do somethings better than men, and like some things men don't like, and dislike some things that men like... conversely, Men do some things better than women, like things women don't like and dislike some things that men like.
YES THERE ARE EXCEPTIONS, but those are tiny number and you don't change everything because someone who doesn't even DO CS work thinks there should be more women in CS work.
Men and women ARE NOT EQUAL. STOP TRYING TO PRETEND THEY ARE.
If you think men and women are 100% equal, then you haven't paid attention to even basic anatomy.
I'm not saying one is better than the other, I'm saying they aren't the same and its fucking stupid to keep shoving shit down the throats of one of the sexes just to appease some douche who things he's crusading for the good of all women.
The problem is the traditional dial in interface for voicemail sucks sour frog ass.
Pardon my ignorance, but who does that anymore? The Cisco phones I've seen have a menu (small one, but its there) that you can see caller id, time and length of each message and select it directly.
I'm an iPhone user, so I have visual voice mail and wouldn't even consider using anything that didn't.
Doesn't Android do something like visual voicemail as well?
And of course, as you said, there is Google Voice if you really do have a shitty phone/phone service, GV will take care of your shitty phone service and provider.
I just really don't understand anyone that doesn't have something like visual voice mail.
He didn't provide a good reason. Sure, sometimes IMs make sense, but not for any serious discussion. If you think you can have a serious discussion over IM you have some serious social issues and I'm fairly certain you do it poorly.
Everyone forwards their work number to their personal mobile phone? I'd say that is a ludicrous assertion.
I work at a phone company. No one has a desk phone, we all have desk phone numbers, we just forward them to our cells. We provide specific features to our customers for having virtual office numbers that work with their cell phones in a nice way.
You also seem to fail to recognizes that a great many companies subsidize cell phones, and all the ones without office phones either provide a cell phone or subsidize the employees. Most just subsidizes the employee phones so that can get what they want.
I don't even believe our Cisco system is setup to allow forwarding.
So your company either does something that legally/procedurally prevents them from being allowed to do so, or your company is just ignorant of the world around them. Not sure which, but if your system doesn't allow forwarding you are NOT the norm. I'm guessing you're required to be at your desk during the entire work period, in which case there isn't any need to forward it somewhere, IS THERE?
Years ago I did, but then dilholes from overseas would call me on it in the middle of the night for something that should have gone to the level 1 help desk.
So you work for a stupid company who allows that sort of shit to happen, stop telling me about how other companies behave, you don't know how they behave, clearly.
We finally have a system that puts an attachment with the voicemail recording into your email inbox so that you can more easily take the calls out of order
Congratulations, you just caught up to what was available in 2001 for free.
I usually don't play it for about 2 days - part of the training program to get people to use other options for contact...
Oh so you're just one of those irresponsible assholes who thinks he's special, sorry I wasted my time responding.
Turning off desktop phone voicemail BECAUSE EVERYONE USES A CELL PHONE and has their office number forwarded to that anyway does not mean people aren't using voicemail.
But hey, don't take the extra three seconds to ask why they were not using it or anything.
we know we've caused the recent one by increasing CO2 by 40% and measured its affects.
No, we don't KNOW that. You seem to fail to understand both science and history.
We have observed indications that we're producing far more CO2 than is being consumed. We've extrapolated that out to a theory that we're causing AGW.
That doesn't mean we know that to be true, because we do not know, it's a fucking theory. They call it that for a reason. Thats where you fail at the science portion.
Your history failure revolves around the fact that your ignorant of the countless number of times that our science has been flat out wrong even though the conclusions drawn from our observations were sound. Do you have any idea why? Because the physical world reacts based on countless bits of matter interacting with each other and exchanging energy, and only an idiot doesn't recognize that it is physically impossible for us to observe all these interactions, let alone model them.
We have no direct observations from prehistory, only observation of the results, from which we speculate on what happened. We've been wrong on pretty much everything we thought we knew about the past... Repeatedly.
You have to be a mindless pleb to not recognize how little confidence you should have in historical information derived from indirection information especially when it keeps being "corrected".
Your treating the science of AGW as a religion not science.
You were just shown many citations that rapid climate change happens without people producing CO2. You have absolutely NO IDEA WHY those events happened, yet your positive we know why this one is and it's not the same as before. That makes you look pretty stupid. Your just as bad as the climate change deniers, absolutely the same.
You're doing nothing but hurting the entire discussion with your ignorance.
So a company that has always lost large sums of money, is not getting any better at losing less money... and has always depending on funding to just pay the rent... raised a 0.5 billion dollars... to go up against a company that has track record of doing things well and is so profitable it has like 700 billion dollars in the bank...
BWAHAHAHAHAHA
Someone just lost have a billion dollars because Apple can do the same thing spotify does with that money... and then do it another 1399 times while Spotify is wondering what ran over them. Its not a contest.
People buy quality hardware? People who don't want to use a shitty OS thrown on random hardware with half assed drivers that cause regular crashes?
When will you people ever understand that it's not 'Just a PC', it's a well engineered package.
If you think people buy macs only to write software for Apple devices then you don't seem to have any experience with those devices and probably shouldn't comment on them.
No. Stop being a cheap ass and buy the tools required for the job. Do you sit around and bitch because you can't put your DVD into a CD player and get video?
If you are too cheap to buy a Mac and use the right tools, than neither Apple or OS X or iOS users want your software, you'll almost certainly do it wrong and try to throw a Windows or Linux looking UI and UX conventions on your app and it will most certainly not fit in.
Again, no Apple user wants the shitty Windows or Linux 'I invented my own UX guidelines' crap your likely to try and push. Apple users don't like crappy half assed ports, they want apps that feel native which you can't possibly make since you have no clue what native and intuitive are.
... Well there isn't much I your post that's correct.
Red hat certainly didn't "make" the things you mentioned, they contributed to them, and in most causes were not the biggest contributor.
Second, you don't know shit about how red hat the business makes money. The majority of their income comes from investments they made based on income during their IPO.
Red Hat isn't a Linux company any more. It's an investment organization that also sells some Linux support.
Being publicly traded company this is all public record if you bothered to look.
If they hadn't invested from their IPO, they'd be out of business by now.
The irony with Christians hating evolutionary development and the story of our cosmos is that Christians are mostly the ones who discovered or verified the data. They freak the fuck out if you point out that they took a metaphor and treated it as literal and factual when it was never meant that way.
There is nothing you can do to fix the ignorant that refuse to learn.
You can't convince them that a Catholic postulated the Big Bang Theory, but tell them God created the earth in "7 days" and they'll eat it up. You can't even define days without the light, and that wasn't there for until the Sun was formed on the 4th fraking day!
Not implying Darwin was a Christian either, but plenty of Christian scientists have verified and agreed with his theories or helped refine him.
If your going to teach religion in science class, it's just as appropriate in English, Math, or home economics. I.e. It doesn't belong in any of them
If you're trying to use 2 AA batteries to power a 2.7v device, you're just stupid. You don't get to blame the semiconductor company and the laws of physics for your inability to make a design that functions.
Rechargable AA cells NEVER REACH 1.35v to start with.
You're essentially bitching about the fact that you under power the device because of a bad design.
GNU/Linux is a SysV bastarded child formed by merging a pretty great kernel with any number of half assed intentionally incompatible in subtle ways user land utilities.
Nothing about Linux is BSD or UNIX other than the feel. Windows is in fact more UNIX than Linux is, with its posix certified interop layer that Linux supports well, but is not certified.
A older version of OS X is UNIX and Posix certified.
Yea, managed by assholes like that... Knowing how they already treat their employees/drivers...
They didn't get top researchers, that got the idiots to stupid to realize how much your fucking yourself over by willingly going to work for Uber.
Are you really that stupid? You think leaving a stable Uni to go work for "the most punchable management shit weasels" is a smart plan? You think they'll follow through on all their promises and standard social contracts for these guys... But otherwise will shit on all the rest of society world wide?
There's a VERY solid chance uber won't exist in a couple years when governments finally get tired of their bullshit and fine them into oblivion... At which point your just fucked because everyone else in your field knows about the morons who jumped ship for a big paycheck at a really shitty company.
Let me drop a 2 pound drone on your head from just 10 feet above you.
IF you survive it is unlikely you'll make such ignorant statements ever again, and I'm not even talking about loading it up with ordinance or even simply flying into you at high speed.
It's is trivial for a 2 pound drone to kill you by accident, all it takes is the most minimal effort to do it intentionally.
DC is in fact absolutely shitty for long hauls, and that is in fact why we use AC.
Power plants run alternators at specific RPMs intentionally to produce AC. There are no American hydro power generation stations using DC. That would be stupid. Every single one of them uses 3600 hertz multiphase output, one of those phases will give you 60hz AC.
The parasitic losses of DC over long distance is reason enough that it's not done, when you couple in the fact that it HAS TO BE AC in order to do any sort of reasonably efficient voltage conversion just seals the deal.
It's used in SHORT haul international interconnects when each side uses different frequencies for their grid OR when they don't want to stay phase synced.
DC is stupid for normal people for anything other than the last leg, like between your Wallwart and device.
There are three ways to cut down DC voltage: convert to AC and use a transformer, use PWM and large capacitor bank to smooth it back to DC... Or resistive and essentially turn the extra voltage into waste heat. All of those suck, the last most of all, but also the one that can handle large loads best.
There is one way to boost DC voltage. Convert it to AC, or at least half wave AC and use a transformer.
Heh I should have read your whole post before replying to the first line, but let me pick you apart in another one instead.
1. Most stuff just works on high voltage DC as discussed above. Most switching power supplies simply don't know or care about AC or DC and due to their efficiency switching power supplies are used in almost everything electronic.
Absolutely wrong. The first thing most power supplies do is step down from high voltage AC to something in the general range of whats needed on the highest output value. They step down with a transformer. That transformer only works with AC, if you put DC in it, you're just going to burn it up as it turns into a magnet carrying more current (because its not AC, so the there is no inductive resistance, so there is more current). Please don't give anyone advice on electricity. Ever.
2. It's easier (and more efficient) to use high voltage DC for charging the batteries. All you need is a rectifier to convert that 220 into about 250V DC and charge the batteries, which is about as simple and efficient as it comes.
... You do realize those batteries you're referring to are actually made up of a bunch of smaller batteries right? There is no single cell at 200v. You aren't charging one 200v batter, you're charging a handful of 12v batteries that you're just blissfully ignorant of.
3. It's easer (and more efficient) to make an inverter that uses high voltage DC as input. It's pretty easy to just flip the current one way then the other to get AC sufficient to run most induction motors and transformer powered devices.
You have absolutely no idea what you're talking about. The conversion from DC to AC is THE BIGGEST LOSS in the inverters you're referring to. The actual transformer itself is pretty damn efficient if designed properly. Dealing with high voltage DC is extremely dangerous. It ARCs over distances that AC won't. You can put 200v AC traces on a circuit board with little space between them. Do the same thing with the same DC voltage and the board is going to randomly arc all over itself.
4. It's more efficient to use higher voltage in terms of wire size because IxR losses are less for the same power transfer. Chances are the same wires you have now will be fine, but if you go to low voltage (say 13.8V like in your car) you are going to need bigger conductors to avoid the voltage drops over long high current runs. Use higher voltage and lower current, and stick with the wires you have.
The first part is true, larger wires are better for lower current loss. The rest of this is false. DC has different properties than AC. Insulators, wire spacing, and load will behave differently at 200v AC versus DC. You CAN NOT use the same wiring unless you want to burn the building down. Please don't ever tell people anything about electrical wiring, you're going to get someone killed.
The rest of your post is pretty much factually incorrect in everyway as well, but I'm tired of pointing out how little you seem to know about the subject. Again, please stop trying to tell people things like this, its fraking dangerous and people could die from this ignorance.
We need to use HIGH voltage DC at about the same voltage as your house is now, forget about going "low voltage" DC.
No, we don't.
120v AC will kick you off of it if you touch exposed wires.
120v DC will cause you to clamp down if you grab onto a wire or device that electrocutes you, and worse still, it'll kill you at much lower voltages than AC.
On that alone, HVDC is stupid in the home.
Thats ignoring things like how circuit breakers and switches behave under DC verses AC.
AC has a ridiculous number of safety advantages that are not present in DC, which is why you RARELY see high voltage DC.
Couple in the resistive losses of DC and HVDC suddenly looks really stupid to anyone with a clue.
Did you seriously just use a list of tabloids as an example of 'fooling millions'?
If so, you must have been born yesterday since tabloids aren't exactly new and are in fact designed around 'fooling millions' on a daily basis.
Just because they print a lot doesn't mean they're reputable news sources.
Oh, and by the way, Katie Holmes is an alien. She didn't used to be, but Tom Cruise has her DNA manipulated by Xenu so now she's like the chick from Species. Its all over the cover of Daily Star.
Its like you guys thought that line in MiB where he says all the best news comes from tabloids wasn't fictional. You know MiB was just a movie too, right?

1. Most stuff just works on high voltage DC as discussed above. Most switching power supplies simply don't know or care about AC or DC and due to their efficiency switching power supplies are used in almost everything electronic.
Absolutely wrong. The first thing most power supplies do is step down from high voltage AC to something in the general range of whats needed on the highest output value. They step down with a transformer. That transformer only works with AC, if you put DC in it, you're just going to burn it up as it turns into a magnet carrying more current (because its not AC, so the there is no inductive resistance, so there is more current). Please don't give anyone advice on electricity. Ever.
2. It's easier (and more efficient) to use high voltage DC for charging the batteries. All you need is a rectifier to convert that 220 into about 250V DC and charge the batteries, which is about as simple and efficient as it comes.
... You do realize those batteries you're referring to are actually made up of a bunch of smaller batteries right? There is no single cell at 200v. You aren't charging one 200v batter, you're charging a handful of 12v batteries that you're just blissfully ignorant of.
3. It's easer (and more efficient) to make an inverter that uses high voltage DC as input. It's pretty easy to just flip the current one way then the other to get AC sufficient to run most induction motors and transformer powered devices.
You have absolutely no idea what you're talking about. The conversion from DC to AC is THE BIGGEST LOSS in the inverters you're referring to. The actual transformer itself is pretty damn efficient if designed properly. Dealing with high voltage DC is extremely dangerous. It ARCs over distances that AC won't. You can put 200v AC traces on a circuit board with little space between them. Do the same thing with the same DC voltage and the board is going to randomly arc all over itself.
4. It's more efficient to use higher voltage in terms of wire size because IxR losses are less for the same power transfer. Chances are the same wires you have now will be fine, but if you go to low voltage (say 13.8V like in your car) you are going to need bigger conductors to avoid the voltage drops over long high current runs. Use higher voltage and lower current, and stick with the wires you have.
The first part is true, larger wires are better for lower current loss. The rest of this is false. DC has different properties than AC. Insulators, wire spacing, and load will behave differently at 200v AC versus DC. You CAN NOT use the same wiring unless you want to burn the building down. Please don't ever tell people anything about electrical wiring, you're going to get someone killed.
The rest of your post is pretty much factually incorrect in everyway as well, but I'm tired of pointing out how little you seem to know about the subject. Again, please stop trying to tell people things like this, its fraking dangerous and people could die from this ignorance.
We need to use HIGH voltage DC at about the same voltage as your house is now, forget about going "low voltage" DC.
No, we don't.
120v AC will kick you off of it if you touch exposed wires.
120v DC will cause you to clamp down if you grab onto a wire or device that electrocutes you, and worse still, it'll kill you at much lower voltages than AC.
On that alone, HVDC is stupid in the home.
Thats ignoring things like how circuit breakers and switches behave under DC verses AC.
AC has a ridiculous number of safety advantages that are not present in DC, which is why you RARELY see high voltage DC.
Couple in the resistive losses of DC and HVDC suddenly looks really stupid to anyone with a clue.
Did you seriously just use a list of tabloids as an example of 'fooling millions'?
If so, you must have been born yesterday since tabloids aren't exactly new and are in fact designed around 'fooling millions' on a daily basis.
Just because they print a lot doesn't mean they're reputable news sources.
Oh, and by the way, Katie Holmes is an alien. She didn't used to be, but Tom Cruise has her DNA manipulated by Xenu so now she's like the chick from Species. Its all over the cover of Daily Star.
Its like you guys thought that line in MiB where he says all the best news comes from tabloids wasn't fictional. You know MiB was just a movie too, right?
