'Hypersensitive' Wi-Fi hater loses case against fiendish DEVICES

Re: Think of the Children!

You can get audio at the difference frequency between Video and Audio carriers, and harmonics, so 6MHz, 12MHz, 18MHz etc for 625 TV. About 4.x something MHz on 405, long time ago, I don't remember.

The Audio IF strip if on carrier rather than "intercarrier" is 6MHz below video IF usually, so about 33MHz approx for 625 line.

USA used 44MHz Video IF and Europe usually 39MHz approx for 625 line. Earlier 405 sets used various frequencies from about 12MHz to 44MHz. Earliest 405 sets simply tuned one 42MHz approx channel directly with NO IF, later in 1955 the first set boxes sold for Band I only sets to get ITV on Band III

Yes, it's been done and the "electro-sensitive" people would score as well tossing a coin to answer if the transmitter is on or off.

So ...

Spinning disks are not "dead" then if cost and storage is more important than latency. Arrays do reduce the latency issue a bit.

It seems we are nowhere near the limits of increased disk density, though no large jumps in capacity.

Could it be that NAND Fab plant building isn't happening because perhaps it's still a premium price niche market as well as the uncertainty over alternate technologies. I think there may be more than the three mentioned in the article.

Losev was tragic loss

Marconi's assistant told Marconi about the glowing crystal, but like many successful entrepreneurs, he had a single obsession, to make money from Radio. As it wasn't a good radio detector, he wasn't interested.

I knew Losev had published about LED. I didn't realise he had an LED patent though. He also described a "Transistor" (not called that then) but unfortunately most of what he wrote on that was destroyed in the War.

HP: PC industry has forgotten how to innovate

Coffee/keyboard

What?

Duh, it's either a clamshell rectangle with screen and keyboard or a box that a screen & keyboard plugs into.

If it is portable it shouldn't be too heavy and the big innovation would be 8 hours + life instead of approximately 3 to 4 we have had for ten years.

The screen and keyboard shouldn't be shiny.

The keyboard should not get jammed with hair and crumbs.

It should be reliable and fast enough (1/10th second response worst case to any action).

It should have all the I/O required and spaced such that something in one aperture doesn't block the neighbour.

Stuff like ultra thin, alloy casing, carbon fibre, funky translucent plastic or what ever is irrelevant unless it is needed for above.

Might be perfectly true ... But

"Huawei is entirely owned by its employees. No third party - including government institutions - has any ownership interest in Huawei," he said. "Huawei’s success has not been based on favouritism or subsidisation by the Chinese government."

But that doesn't rule out that Huawei does whatever the [Chinese] Government asks. It's certainly interesting to see who has been sold what for how much in Africa and what China gets out of it.

Some non-Chinese companies are no different and even do it for highest bidder.

This supercomputing board can be yours for $99. Here's how

Mage
Silver badge

Re: It's all about timing

Actually the problem with Transputer was it needed a different way of programming and thinking. Traditional OS and programming and libraries and existing applications can't be sensibly run on such highly parallel systems.

So not about the timing. Transputer was only ever a niche product in a market that Intel with hugely more resources has struggled with. If the Transputer had been an Intel or US invention, animation Render Farms would be running Transputer based 1000s of cores per chip and 1000s of chips per rack today.

Re: What about memory bandwidth ?

Seriously multicore systems need a lot of memory per core. This is advantage of fine grained muliple core RISC etc vs 1 billion transistor Chipzilla coarse grained multiprocessing cores. You have space for RAM for each core on chip. With coarse grained cores using OS threads, you have a serious memory bottleneck beyond 4 cores. More than 8 off x86 cores is silly unless you have multiple external buses to multiple RAM.

Re: Intel & IBM & MS

I think some people that have never done parallel programming don't understand the differences between a language where the compiler or run time time takes care of co-routine / thread / process to core mapping and a language that only has libraries for the host OS (NT, LInux, Unix etc). Or don't understand the difference between OS based Multiprocessing and Language based. Or between multi-core and distributed system.

Intel's x86 multi-core are not hugely different to a Motherboard with 2 or 4 single Core CPU sockets. In both cases NT or Linux hard sees the difference. Most actual programs can't tell the difference at all and only run on one core. Beyond 4 cores the speed improvement is marginal for NT Windows or Linux.

Systems with 100s to 1000s of cores (ideally each with enough RAM to run instructions in parallel without a memory bottleneck) need a different way of thinking and programming to take advantage of them. While people have done clever stuff with patched custom Kernels and exotic C and C++ and Fortran compilers and clever libraries, that's a dead end for huge numbers of cores/cpus.

While all this is well known to those working in HPC, Parallel systems etc for 30 years, it seems not well known even to many programmers.

absence of WiFi connectivity

Because it's a horror story to support.

I worked in an ISP doing cable broadband. I argued that since unlike DSL people can't buy their own Router, the modem should JUST be a Modem and then people buy their own router with whatever flavour of WiFi they want.

You'll find very very few TVs or setboxes with WiFi. Especially ones sold by people that might have to support it for "free". Ethernet is far more reliable and needs little support.

Ian's Brother was probably the "real" spy

Peter Fleming's books are less numerous and more intriguing for what they don't say.

News From Tartary

The Bond books are "Chitty Chitty Bang Bang"* for adults, escapism and not meant to be realistic at all.

(* Yes Ian Fleming was responsible. At least there wasn't a dreadful fake Cockney accent, I think it's possibly better than the Bond Books. I think Leslie Charteris then and Clive Cussler now are better authors of "Bond" type books. The success of the film franchise can't be denied. Sean Connery is my favourite Film Bond.).

It once had about 98% install base, but few users had decent data packages.

Out of the gate, most iOS users used the phone on the Internet while only a few % of Symbian users did.

So it's not just market share of sales today or % install base but the data packages and sort of usage. If you only want to make phone calls why buy an iPhone or Android at all?

EE sets October date to power up UK 4G network

Mage

Speed

Speeds are ALWAYS headline speed, for perfect signal and no other users!

So average cell location = 1/5th of speed or less.

just 6 simultaneous users streaming video

Real speed becomes (40/5) / 6 = 1.33Mbps! Not 40Mbps.

now you know why 3G's 21Mbps is poor.

With about 15 users the "code noise" of CDMA of course means that you have 1/30th not 1/15th speed. So everything else being equal, LTE is twice as good (in same spectrum) but only to the extent of getting say 0.5M to 1Mbps instead of 0.2 to 0.5M, or letting the operator connect 20 users instead of 10,

The other "speed" improvements are simply having more spectrum. Which won't apply at 800, 900 or 1800MHz generally, but only at 2600MHz.

5MHz = 21Mbps (same as 3G HSDPA!)

10MHz = 42Mbps

20Mhz = about 100Mbps

But only for perfect signal. Speed at cell edge is typically 1/100th! All for only one user!

see comparisons of performance vs distance and numbers of users.

Yes, LTE is better than 3G. But if Everything Everywhere get an economic number of customers it will be a slightly faster poorer coverage version of 3G that costs more. No SMS and voice to cross subsidize it. SMS on GSM & 3G costs nothing. Voice is about 1/150th of the traffic for same revenue on 3G. Which is why Three makes no money.

Re: Ireland

LTE is best suited to high density Urban and Suburban.

Depends what you want with your large rural cells.

If you want Mobile voice, then GSM (or even 3G might be better).

If you want Mobile Data, on a large lightly used cell not much to choose between LTE, 3G or even GSM's EDGE+

If you want Rural Broadband, then forget about ANY mobile solution, it won't be reliable, may not connect etc,

Mobile never ensures a connection or a QOS and has no real control over contention other than dropping connections or a poor cap.

Roof top fixed aerials and Cable Broadband over wireless will give reliable 800MHz Rural Broadband. With always on, contention decided at install time and guaranteed speed of 3Mbps to 20Mbps MINIMUM according to how much you spend. Cheaper than LTE and x8 to x16 more capacity per MHz! In use worldwide for years.

LTE is a solution for MOBILE data to complement fixed Broadband. It's not and won't ever be a Broadband solution and certainly not the best Rural Wireless solution unless you need MOBILITY.

Digital Dividend

Actually with 3D, Ultra HD and all those stupid shopping channels we don't actually have TV spectrum to give up.

There is plenty of badly utilised Spectrum from 900 to 2500. So the Mobile operators will have

800

900

1800

2100

2500/2600

Will the consumer get genuinely better coverage, better prices, less dropped connections, guaranteed minimum 3Mbps? No.

Because the regulators are not insisting on enough masts and not insisting on a RAN on each band.

Also 800MHz LTE will interfere with Cable Broadband, Cable TV and Digital TV.

Spectrum management seems to be just a revenue raising exercise. That isn't why independent Regulators from the P&T ministries were created.

Ireland

In Ireland the upper part of TV band (800MHz digital Dividend) will be free from November 2012.

Unfortunately the Comreg auction plans are gross stupidity.

Of course actually 800 should be paired with GSM band to make one more efficient band with the current licence free 864MHz SRD gadgets in the middle of the duplex split guard band.

With current proposals the 800MHz and 900MHz bands will BOTH have an unused part in the middle, AND the gap at 862MHz to 876MHz ish..

Don't fool yourself. The Digital Dividend is a myth. A small short term licence revenue, a waste of a national resource and just something not much better than 3G at 1800MHz would be. The low frequency means you can't have small cells.

Large cells means poor capacity or poor speed.
