Your 440V @ 20amps giving a charge rate of 8800 W is not going to cut it. You get 7KW from a home charger.
Roadside rapid or superchargers are 50KW up to 150KW these days, with 350KW coming soon. So at 440V that is 795amps - a chunky heavy cable.
The Tesla 150KW chargers use 480V DC, the higher power ones will be moving to 800V.
As a home based worker most of the time I got an Openreach based ISP connection as a backup to my Virgin media (consumer) connection. Put them through a dual WAN LinkSys router and I have a load balanced and fail resistant network. Some websites get funny as my IP address changes during the session, but surprisingly few.
Connections are 350/35 on Virgin and 78/19 on the FTTC one, overall cost much less than a business line from one - which wouldn’t help with outages anyway, just might mean more info and compensation.
Ha ha ha ha.
Azure Dev Ops as they are calling it this week is the only thing that has made me pine for JIRA/Confluence. The git part of it might be ok but the rest is super shite.
Wiki that won’t export pages.
Can’t get a notification when a wiki page changes.
Task item editing that needs a save button (hello floppy disk icon...) to keep changes.
Pipeline pages that have changed format about three times in the 5 months I’ve been forced to use this shite.
And they are promising/threatening another big UI change any time now.
Avoid at all costs (and it isn’t even cheap....)
Virgin are so variable. I've been with them a few years now, and I get more of the up to speed than I did with ADSL - but don't normally test it in the evening (but never noticed serious streaming problems).
I did have a long period where it would drop out a few times each week - often mid morning: noticeable when I was working at home. It got so bad (and customer support were the usual chocolate teapot of usefulness) that I got a VDSL line from someone else and a failover/sharing router - Linksys LRT224. That has worked nicely to smooth out any problems - and as far as I can tell the VDSL has been stable (and quick ~75/19).
More recently (last six months) Virgin finally rolled out the 200Mb service in my area (after years of missed promises) and some initial problem I've checked and I've had one outage of 9 minutes since the end of March on the Virgin line, which I'm not going to complain about for consumer grade product. Don't check the other one but the router says connected for 9 days - so something happened.
I guess because the Virgin network is put together from varying quality bits and pieces they bought from others they are going to vary around the country. [Not apologising for them - they are scum on pricing for existing customers, not rolling out new tech until a competitor gets close, (lack of) customer service, marketing spam etc. etc. - but they are generally predictable scum working with shit infrastructure that customers wont pay to have improved.]
Precisely - government departments should have to publish details of every deal they do so we know who is getting backhanders from who. If the vendor doesn't like their prices being published then so be it - find someone who is not too embarrassed to share their price in public. It's *OUR* money they are spending, and we (should) have a right to see where it is going.
No source code is submitted - just the binary package of app + resources, and a symbol/map file. All the system frameworks are called dynamically so they can scan the app to see what it calls to, and the biggest problem is false-positives if you use a method name in your own code that matches a private API: it flags you up.
But beyond an automated scan they don't do much - certainly not launch it on each device it is supposed to run on as there have been enough apps released that crash immediately on certain device types due to a lack of testing.
There's no auth key needed to install XCode. Developers would have used legit publishing keys *inside their project file* that they got from Apple as normal. It is just the size of the XCode download at over 4GB that was causing the developers to look for alternative sources.
As long as the malware didn't use any private API calls it would get past App Store review - and accessing the clipboard, throwing alerts etc is all OK.
Not true for home recorded content. They have a great +1 minute button on the remote, so the standard 3 or 4 minute break can be jumped in seconds once you get used to it. -15 second button too for when they are 3.5 minute breaks. Also has the standard x2/x6/x12/x30 ffwd button too.
On demand players for the commercial channels do restrict it - but that is the develover of the demand player not Humax limiting it.
The article is spot on.
Had the horror of a Samsung 'smart' TV and apps - thought it couldn't get worse until I got a View21 HD Recorder - interface on that is so *very* slow, full of bugs and silliness that anyone with a clue would have spotted before release. Already had to do a factory reset and wipe the hard drive of recordings after about 3 weeks of use when it hard crashed.
Only TV recorder I've used that was any good was PlayTV on the PS3 - and that is just SD and single channel recording, but the interface was built by game developers and is slick - rapid response, no crap just does what it should. Paired with a blue tooth remote it's great. [Why are TVs still using IR remotes? They suck compared to bluetooth and the batteries in the PS3 one last for ever with tons of use] iPlayer on PS3 is a mess though - have to get the trad controller out for some operations.
3D printing should lead to less people fixing things - the cost of replacing an item will tend towards the price of raw feedstock and a bit of energy. Will eventually always be cheaper to print a new one than fix the old one.
For a while 3D printers will help those who fix things by printing out a new spare part for the larger item, but before long they'll be able to just print a whole large item. Fun times ahead.
If the platform needs it then he can use the same vectors as a virus would use to infect the platform to publish+run an anti-virus scanner/cleaner.
On a more sensible note: an AV scanner basically needs to be integrated at the OS level on a platform where all apps are sandboxed, so he'd need Apple support to develop and release it, and who is to say that an internal team at Apple, or one of Kaspersky's, don't already have AV software running in the OS on all devices?
The iPhone one is probably just everyone using the same sample code (http://developer.apple.com/library/ios/#samplecode/Reachability/Introduction/Intro.html) for their 'is the internet' reachable tests - the sample uses www.apple.com as the target URL to test for WAN access . I know I've just cut+pasted that into apps where I needed to know network status, and I suspect it would trigger a hotel wifi re-direct page when it runs.
A flat rate volume pricing model works for me - if I decide I'm going to make Spotify my primary music player/library/purchase place then paying them £50 to get 50p/track works - given the time taken to hunt around all the other stores trying to find a 'bargain' price on something I think I'll take the slightly higher (but probably average out to 0 difference over the long term) price per track and simplicity.
I get so fed up with myself for spending minutes/hours trying to save a few £ on something when I should know my time is my most valuable thing - I'll never get more of that. My target rate of time spent hunting to reduce the price on something I'm going to buy vs the money saved is 5-10 times my effective hourly salary depending on my mood - problem is I tend to forget that until I'm far too far into saving £5 on a £100 item....
Why do you need cursor keys with a touch screen? If you have a physical keyboard then sure, but with an onscreen keyboard?
I'm not an Android user but GoodReader on iOS devices has full read access to the google docs so there is obviously some API for getting to them - maybe writing isn't exposed yet though.
Editing a spreadsheet google doc on iOS using the Google app/web browser was a painful experience and from the screenshot in this article it looks to be the same on Android - things can only get better yeah?
If "Using a single-core 2.2GHz AMD Opteron with 2GB RAM, sieving would have taken about 1,500 years" then a 10,000 machine botnet takes 54 days or so. So a 70,000 machine network is a week, assuming they are all just single core and are running 24x7 [big assumption I know - I'd expect faster machines on average, but not running 24/7].
Alternatively how much would it cost to rent that much CPU time on Amazon's cloud?
