Re: Iceland

Just one quick point - the condenser coils are unlikely to be iced up, given they're pumping out heat.

The engineer arriving to fix one that's been dead for a day or two, yes, they might have their work cut out!

Re: Is it naive to suggest ...

I'm here to literally ask the same thing. On the assumption that the jamming is originating from the ground, and the desired signal is originating from the sky, is it possible to solve for that?

I suppose the challenges are likely to be to do with any additional weight, certifying the newly redesigned receiver as sufficiently accurate and reliable, and the risk of your adversary emitting a jamming signal from another aircraft.

I use uMatrix, set to disable javascript everywhere but it allows me to express which domains can load javascript on which sites (so I can allow first-party JS on a particular domain)

I think that strikes a sensible balance; by default everything is blocked apart from what I specifically allow.

Re: Amazon link?

That could well explain the behaviour; if (for example) Talktalk have private peering to AWS and CloudFront then that link being at 100% might mean that Prime Video, Twitch and AWS-Hosted sites would be slow, while services hosted via other network links into TalkTalk would still be seemingly fine.

Re: But...

Where's this 5-8 year figure keep coming from? Have a look at the following article:

https://electrek.co/2018/04/14/tesla-battery-degradation-data/

It seems that total and utter battery failure is very rare, and the more common degradation due to use really isn't such a profound issue.

I'd imagine that your average 150k mile car will be getting worse MPG than its best, and might well have the looming bill-cloud of a new turbo / dpf / injectors hovering over it, poised to strike in much the same way.

Fortunately if the battery is degrading due to use, you've got the choice of whether to replace it or accept the lower range. If your was-250-now-200 mile range car is only used for commuting, you might not be so bothered. If your petrol car needs a new GPF and clutch, you've probably far less choice about whether or not to pay to repair it.

I'm not saying that electric cars will be without their flaws, but please let's not forget that petrol/diesel cars that are getting on a bit are also vulnerable to large bills.

Re: "Gigabit class wifi"?

As a few others have alluded, it's not that people are in need of a sustained 1gbit for hours on end for $task, it's that some limited tasks become much smoother with a higher speed connection.

Take even streaming video now at 1080p. Might only need 20mbit; but if your player wants to buffer 10 seconds of video in RAM before it begins playback, the time it spends buffering will drop to almost near-zero with a gigabit connection.

I write this from the lucky position of having Hyperoptic* 1gbit internet. I've found that I've stopped really caring about 'the internet' in terms of speed, stuff just works. If I'm sending a multi-GB file to cloud storage, it's done in barely no time at all. If I want a 15GB patch to download, it's done in the time it takes to make a cup of tea. A friend of mine languishing on 10mbit ADSL has to leave his computer on most of the day to grab the same updates in time for a gaming session in the evening.

it isn't that I need to shift 50TB of data a month, but that the data I do transfer, I don't want to wait for. I now don't have to.

(*Granted, the speed is lovely. Pity they still haven't rolled out ipv6 to me, nor can they offer a date when it'll arrive....)

Well, not strictly - I mean in the case of Dropbox where they merely used S3 for object storage, but metadata etc was on their own servers, they could have presumably moved an object and then updated the pointer to that particular object to its new home, be it a new S3 bucket, a new S3 region, a new S3-alike provider, or their own infrastructure. The delete from the original location could then take place later.

Then, once tested, you could migrate across in a number of ways - new files written to the new storage, older files moved across in the background.

Of course the migration will have a fee; the bandwidth egress charges from your old provider are going to be pretty high due to the migration!

Re: Absolutely brilliant, except the screen size

I've a Sony Z3 Compact for exactly the reasons you outline. I'm still looking for the same form factor as my HTC Desire - except with updated innards.

Re: Maps

Except the plan is to improve coverage of landmass in general - I don't only want the phone to work at my home or workplace, but on the bits in between...

Re: Sony Xperia Z3 compact battery - replacement?

I own this phone. I can't see any subtle method of disassembly (e.g. screw heads under covers and what have you). Not that I've tried: I suspect any effort would almost certainly damage the waterproofing.

Re: single market?

AAISP Sip2Sim perhaps?

Re: Servicing that demand?

Perhaps they might be looking to set availability flags for each of their datacentres based on the local power / cooling requirements? Windy, cold day in Ireland? Get it doing all the work. A warm still evening with no solar, shift the load elsewhere.

While this might not solve all the problems it could certainly help out.

Re: Huh?

I think it's more that the market expected there to be a gold-rush style sale of new gear (running Windows 7 / 8.1 or similar) to replace old unsupported XP kit, so they filled their warehouses with lots of lovely stock to try and push on businesses and customers that were upgrading.

The upgrade-rush didn't have the scale they apparently hoped for, and now the vendors are staring forlornly at all this gear they didn't sell.

Dual Sim phones

Rather than dual-sim phones, would it not be better if the networks had an easy way to report bad coverage in areas & if they were seen to react to these reports.

Just think - how many people do you know who are on a particular network because that's the only network providing good coverage in a location the user frequents - but they'd be off to a competitor if they could.

Ah, I suppose that'll never happen, will it?

Re: Why 3000mAh?

Why not 3A? Well the capacity is probably measured at a tremendously slow rate of discharge. Thanks to Peukert's Law (http://en.wikipedia.org/wiki/Peukert%27s_law) the relationship between joules delivered and rate of discharge is not linear.

Therefore a 3000mAh battery might only be able to sustain a current draw of 1 Amp for half an hour* rather than the 3 hours a linear relationship might suggest.

*I made this up, did no maths at all to provide that number.

Re: am I the only one

The trouble is that by attenuating the signal from the macro cell outside, your mobile phone will ramp up its TX power to overcome that same attenuation, therefore undoing your careful work.

For me it's also annoying - I live in a new build property near a city centre. Full five-bar signal outside, a flickering feeble bar indoors. A Three HomeSignal has fixed the issue there, but given the postcode they were certainly reluctant to give me one! What forced their hand was that the advisor asked to phone back on my landline midway through the call as the call was breaking up!
