Worse? I would say you must be new here, but I can read useids... It was started by the whole "Fuck Beta" group which confused me (beta, was and as far as I know remains optional), and like all things borne of "violent" revolution suffers a bit from some infighting. Hopefully they'll resolve that, but it remains to be seen if they can build a decent community. I am registered and do read there, but comment more here, which says something.
1. It assumes there is no signal above the cutoff (1/2 the sampling rate). If this assumption is not met ie in the real world, then annoying 'aliases' appear in the sampled signal. To fix this, you have to have a low-pass filter. The low-pass filter, by its nature (physics) has to start cutting out signal well below the theoretical cut0off. So there is inevitable loss of signal well under the cutoff.
Nope. It assumes there is no interesting signal above half the sampling rate(i.e. anything above that should be filtered out prior to sampling. Generally sampling above Nyquist is a good idea in practice because there does not exist a practical perfect linear low pass filter outside of a digital system.
My point to the parent of my post is that he might not give a shit, but there is a place to do so. Perhaps take a minute to read through the end of my post?
They're welcome to monitor me playing DayZ and repetitively dying and being eaten by Zombies at home. I don't give a shit. At work, this could be more tricky.
My brother is a chemist, and they run endless simulations before anyone is allowed to use their NMR machine. I was actually surprised at the shear amount of computing power required, and some basic economics seems to indicate lab time might be cheaper, if it weren't for the fact that the simulations are required by the department prior to lab time. Then again, if electricity is free (it is practically for a department at most universities), it might swing the other way by hiding the cost...
You're spot on. The system is too complicated for evolution to make specific predictions. The general ones may be tested or observed in hindsight, but to make anything other than vague predictions, we would need a lot more computing power/data storage than we have - perhaps more than could exist on our planet. Evolution's value lies not in prediction, but in it's explanatory model. This doesn't invalidate evolution from a scientific perspective, but it does show sometimes that having the final answer makes working through the problem a lot easier.
I immediately turned off the feature on our site. I don't care about it anyway - and my hosting provider seems a little bit daft(need to change them out). According to them we were on the receiving end of a DDOS and their default response is to basically ban all incoming traffic from entire IP ranges, making the website effectively inaccessible from anywhere outside the country(then why have a website at all?). I do not want to give them any excuse to blame me. We were not the target of this specific attack, unless some script kiddies have it in for random small automation companies, which seems unlikely to me.
Political dissidents are actually legal in South Africa, as long as they are peaceful (though many aren't). We are certainly not a functioning democracy, but this is one of the more progressive African Countries. We even have multiple political parties, and the giant struggle party that tends to rule African countries is losing some support.
Back on topic, I quite like Samsmung's feature that lets me remote track and remote wipe the phone. I heard something about google or others providing such a service. Might be a place to start looking...
The question: what makes evolution split the species into these two clearly distinctive species, instead of, say a hundred different species which are something between RockMonster ant and BigAss RockMonster ant?
Who says it doesn't split the ant into 100 different species? The term species is a human invention to help us classify the different forms of life on the planet. It doesn't define the forms of life on the planet, but instead is defined by the forms of life on the planet. This is a subtle but necessary distinction.
I think the point is that a standard network is generally the wrong thing for control - therefore you would not want to hook up standard car navigation/media player devices to your control network, but non standard ones which "get out of the way" when necessary. Ethernet (despite all it's nice features) is really unsuitable for control. I know - I've played around with remote IO on ethernet. Devicenet (aka CANBUS for industry) beats the pants off it in terms of latency at lower baud rates on all but dedicated networks. Wrong tool for the job really.
This is why, unless the manufacturers are really stupid, they'll use ethercat, which does have guaranteed latency and priorities. But car systems will only use a fraction of the bandwidth.
Hangouts and skype are slow and bloated. The majority of the rest aren't quite as popular. Telegram might take up the slack if whatsapp goes the way of facebook messenger, but I don't think you have gotten my point. $1 isn't a lot of money to the majority of users. Something simple and fairly well implemented is quite attractive at $1, especially since the cost per message, while infinitesimally higher is still close to zero. The issue isn't cost since of the above are as good as free, and userbase whatsapp has (or had...) is well worth $1 to most people.
Look at it this way, if you will:
(1+5)/(very large number) ~= (0+5)/(very large number)
Both are as close to zero as to make no difference. And yeah, I maybe spend R50 (~US$5) on data for whatsapp a year.
I've found it generally good enough to make out the part number on a PLC card. A quick pinch-zoom works for that, and I have a fairly large smartphone screen(S3). But yeah, the downscaling isn't great. Sometimes in the modern world, your PC isn't that close, and you have to answer a question quickly. Telegram apparently doesn't downscale, so that might be a better option for you. Far worse than whatsapp is my one customer who insists on sending me MMS video messages of his problem components. Ever try zooming in on a low quality video to get a part number?
Given that they charge US$1 per year, and that the data usage on text is very low, I wouldn't complain much, since as the number of messages tends towards infinity, the cost per message tends towards zero. They may not be free in the pedantic way, but for all practical purposes, for a heavy user, they are as close as you're going to get.
I am also a South African, and have noticed that whenever I take a number for business reasons, their status shows up in whatsapp. I end up using it for all sorts of work related stuff (send a quick picture of a panel/PLC etc). Much easier than email...
Whatsapp is(was?) brilliant internationally. I also discovered changing sim cards for an foreign one let me still whatsapp from my SA number. It gave me a cheap line of communication linked to my number which was really useful, since roaming is insanely expensive. I'll see if it breaks, but right now it has too much momentum to change easily... Too many people I know use it...
I was looking at Zimbra, which looks interesting. Unfortunately back in the early 2000s, someone at my company did all sorts of custom mailboxes and weird scripts, so until I find time(unlikely) to figure out what is going on, I'm stuck. I am only a sysadmin in my spare time...
No, I had a new server and a copy of Microsoft Server Essentials(as part of our companies Action Pack). I installed the new server for testing purposes (as one does), and discovered there was no more exchange. It was a waste of my time, yes, however at the time it didn't seem unreasonable that SBS becoming Essentials wouldn't eliminate the essential reason to get and use SBS.
Pretty much... We installed it on our new server without checking first then had a "uh... wait... Where is exchange?" moment. Turns out Microsoft wants you on the cloud. Or, I dunno, you could just fork out the cash for exchange server. That is, assuming you have an unlimited amount of cash lying around.
This is exactly why I'm running exchange on 2011. Also they killed exchange from SBS when they called it "Essentials". Wish I could ditch it, but I don't have time to rewrite all the legacy stuff that has been added.
Well, having worked with a lot of theorists, the theoretical model is, while nice and mathematically correct, generally shit in the real world. Have a look at how many people do step tests on PID loops. Oh... I think I just realised why I am single... Shit...

I have seen a dupe or two there. Still in two minds about whether it'll free us or dupe us... :P
