They slipped up
There should be no settings if there are not approvals and requisite TX and RX filters.
Cheap poorly made PSUs also leave off the filtering components so will wipe LW/MW/SW Radio reception. A good quality test for any modern PSU or charger.
It's for Penguins, Rooks, McFeegles, Gnomes or Smurfs. Too small for actual humans or even Dwarves.
What percentage would buy XP with SP4 proper File Explorer and choice of skins with all spurious services off by default and no "crapware" pre-installed and NT4.0 Enterprise's support for 16G RAM?
It would boot faster than Win7 or Win8
More Software runs on it.
More memory is free for applications
Maybe MS lost sight of what users actually need and want (not the same) about 10 years ago?
How much "success" has each version of Windows because there is no choice and it's pre-installed?
Re: Used for anything?
But the TV receivers and set-boxes are not reporting which TV mast they hear. Which in 10s of thousands of cases is not the one the Database thinks they are on.
Also in many cases the propagation of the "White Space" device may be x2 to x10 more than expected. "White Space" is a deliberate Euphemism. These gadgets are going to transmit on actually used TV channels. Not separate Spectrum.
Mobile 3G and 4G/LTE has white space in exactly the same sense as TV. Why doesn't Ofcom try this at 800, 900, 1800, 1900 (DECT Phones) and 2100 MHz phone bands?
DECT phones work on auto channel assignment because they are used for short periods and indoors and only share the spectrum with other smart phones.
These "White Space" devices can only be deployed on a dedicated band. It's Criminal vandalism to deploy them IN the TV band as proposed.
Re: Horribly complicated and over engineered
Google "hidden transmitter syndrome" on Packet Radio.
It won't work without a database.
Even WITH a database, it will still cause interference. It's not possible to make an accurate enough database.
Let them use a "Licence free" band.
Re: There are just so many ways this can go wrong
Even if EVERYTHING is done properly this DOES NOT WORK.
The Database can never be accurate enough.
Unless you are on the Settee watching a media centre the cabled keyboard and mice makes more sense.
There are two more reasons than just the batteries. Some of the cordless mice/keyboards even need their own USB micro dongle anyway.
No-one took any notice of the Radio Amateurs. It's Tony Hancock's fault.
Re: Never a good sign
Reminds me of Nokia and British Satellite Broadcasting.
Who in Finland will want the Nokia HQ?

There is another word too... They think they are gods but are only a consumer marketing company with 1 successful service and 2 successful products.
They could always re-jig iTunes for Linux desktop and Android?
Re: And it's actually *programmable*
ordinary "orange" (Neon) dekatrons up to a few kilohertz, designed for display. Argon ones are faster. You can buy "NOS" Hydrogen based Dekatrons from Russia, They are very much faster. Some early desktop calculators used Thyratrons and Dekatrons and no relays.
Re: Try log tables
The Calculators did multiplication by repeated Addition and Division is MUCH harder on a calculator that only does adding & Subtracting than Multiplication.
Earlier Calculators were people.
Our overlords think Mobile or Satellite = Broadband. (They are not, Nor will LTE be BB. Esp. in the 5MHz channels they licensed)
In the Cities the Cable company gives 100Mbps.
Phone lines has dropped from from 82% to 50% due to 3rd world quality and highest in World Line Rental
So your nearly Broadband is better than 1/3rd of Irish population has.
We do have Donkeys and Horses. Sometimes even on the Motorway, which has signs forbidding Horse Buggies, yet there are no Amish.
Why do people think they should be able to run a Mobile Network without bidding for Mobile designated Spectrum?
Anyway, 5GHz only good for Satellite, Fixed point to point or very local "Hot Spots". Really no Mobile should be licensed above about 2.6GHz
Maybe when passive an Atom can use as low power as some ARMs. But actually running the lowest power x86 system can be x5 consumption of ARM system, excluding screen and Transmitters.
He is right.
Jakob Nielsen is very very good. This is really bad for MS.
I have been reading his "common sense" approach for years. He tells it like it is. He has no axe to grind other than usability.
Essentially the GUI formerly called Metro is derived from Zune. It's best for a phone, mediocre for a larger than 6" tablet and useless for a Keyboarded device at desk. They also appear to have over-complicated interaction and dumbed the visuals what was a quite good UI on Zune.
This is exactly to opposite and equally bad as putting the win95 style desktop on a 3.5" phone or PDA. I don't agree with Nielsen though. Two interfaces isn't enough. You need four. One for smallest screens, one for medium tablets and one for mainly Keyboard + mouse desk machines (Notebooks, Ultrabook, laptop, Large tablet with keyboard and fixed Desktop machines).
HDTVs without a keyboard but added "smart features" beyond TV, inc Internet. Try using a true "Media center" [sic] interface designed for Remote control on a Laptop or Desktop, or a regular "desktop" GUI on settee on a TV.
HP, Apple, Microsoft ...
XI (11) is after X (10). After 12 years should they be doing a new major version rather than iteration? maybe though iOS is OS "XI"
Mines the one with Roman Numerals Pocket Watch.
Let's for a moment assume that you can encode information in Spin states. That doesn't mean "infinite" any more than than normal phase, fdm or amplitude is (COFDM uses all 3 by multiple carriers each modulated QAM). You can also polarisation, But only paths with no reflections are any use and more than two states isn't useful.
With any encoding system there is a "distance" between symbols. The more states you have the less distance there is i.e. QAM16 vs QAM2048 so signal is less robust. On Cable 256 QAM is feasible and on fibre even 2048, but on RF it's QPSK (very long range), 16, 32 or at most 64.
If this is a real mode it's unlikely that symbol distance ( immunity to noise) will allow more than two spin states to be useful in an open path. Which may at least double capacity on microwave links. Unlikely to be applicable to portable devices.
Of course the experiment they did might not be using spin at all but only two polarisations.
What sort of useful test is that?
I'd only buy one of these if it was good for Raid 5 or 6.
Shows that Thorn was wrong company to sell Inmos too and why Thorn owned "badges" making TV & Radio ended up as labels on uncompetitive & poor quality Asian stuff.
Why do I read this meandering rubbish.
1. Office built into Windows? Craziest idea ever.
c. Most people don't need Office
e. Competition issues would make IE story look tame.
Such drivel. You have an OS, a GUI and Applications. Good design, ease of debugging etc means these 3 layers should be separate and swappable. Applications shouldn't try to do everything, but one kind of thing, so that they are easier to use, freer of bugs, smaller, faster, easier to design well. Sharing information and "Seemless" use between applications of data is not about a Monolithic system but about good modular design and open standards. Exchange can be realtime via TCP/IP local host sockets (extendible across a network), Named Pipes or persistent via open standards files (which need not be bulky XML).
LESS should be bundled and integrated. About the ONLY thing that should be "bundled" with the OS is a lean DB engine for OS use and optionally for applications, with no clash or restriction on adding your own, so it should NOT use the default SQL ports. IBM thought this was a good idea 30 years ago. The "Registry" is an interface to to a bunch of separate files. It and Filesystem should have been using a real database since 1993.
Yet another totally pointless Matt article. Is he trolling us?
Re: Perhaps a different brand of tablet would of been better?
But the French executed their Royals. England only infrequently and mostly by other Royals, but after Cromwell it seemed a good idea to have them back.
That is on a platform with a future. Maybe HTC should wait a while and buy it up at fire sale prices. The Blackberry IP at least.
So, your car goes great without Road Tax and Insurance too.
It's NOT just about Radio Amateurs. But ALL Radio users. Broadcast radio is a unique irreplaceable resource. Satellite and Internet are complementary delivery mechanisms. Not a replacement for Terrestrial Broadcast.
Radio is used by ordinary public, Marine, Aeronautical, Emergency Services, Telemetry and Control of remote equipment by Water, Gas and Electricity Distribution infrastructure. RFID/NFC can also be jammed by PLT. Remote controlled "Toys". CB, Mobile Radio on Trucks, Taxies etc is impacted by the newer high speed units.
Aeronautical and Marine also use HF band as well as the VHF 110 to 137MHz and 156 to 162MHz approx bands. The land based stations will be gradually degraded on HF by ANY PLT ethernet in the Home and VHF links by the higher speed newer units. It's cumulative too as more units are added.
People pay for licences on a Non-Interference Protected Primary basis.
Overall a good article and highlights the biggest issue in UK and Ireland about Radio Interference in General
1) People don't make an official complaint
2) There is no simple mechanism to make a complaint.
3) Even when the Regulator comes on site and proves the TV, phone charger, CFL lamp or PC PSU is creating 100s of times more interference more than legal limit and completely blocking Radio even 30m away, nothing is done, even if it's just faulty and could be replaced. Perhaps they might talk to maker. They will NOT get involved with Retailer or SOGA. Also the neighbours can't go to small claims court over SOGA. Only the Purchaser
The Regulators in UK & Ireland have forgotten why they were created. NOT to serve narrow commercial interests but ALL consumers of Radio Spectrum.
much to the annoyance of the UK amateur?
They are trying to help EVERYONE using radio from 1MHz to 200MHz.
This technology isn't compatible with any form of radio. It will get worse.
Each generation of Networking over mains uses more Radio spectrum. Amateur Radio will suffer the least. as it implements "notches".
These are really wide band transmitters that happen to plug into the mains and where the wiring assists the signal.
Well, duh, due to difficulty of buying a new PC with XP, Win7 or nothing pre-installed, what ever sales of "new" PC kit that would have happened is going to happen anyway.
What if NO Apple Mac or PC had an OS pre-installed and you could SEPARATELY chose OS X, Redhat, Debian, Ubuntu, Solaris, Suse, XP, Win7 or Win8?

Re: Why do I get a feeling of Deja Vu ?
And that one was bunkum too.

Call me a sceptic
But doesn't this somehow contravene the concept of conservation. What next? A Perpetual Motion machine?

They definitely called it an iPad App on R4 "Today" at breakfast time.
Colour vs brightness
Since the colour is by a filter, inherently the better the colour the less light there is. If the filters perfect you'd lose 2/3rds of the light as the Red filter blocks all the green and blue parts of spectrum to get the red colour.
Hence if you have pastel "weak" colour the filter blocks maybe 10%.
So they can't make it much "Better". It's physics. If you are using passive filters and ambient light then maybe 50% to 60% reflection with very pale colours and no better than 28% to 33% with good colour.
Mirasol can achieve the brightest passive colour display as it's mirrors, not pigment/dye filters and LCD.
The LCD polarisers also lose light.. The LCD itself can be pretty clear.
Re: DAB should not be more expensive
They would just use it to have slightly lower quality and twice as many stations to reduce the costs.
Re: Blowing air
Yes, DAB needs about x6 more TX sites and double the number of multiplexs or half the channels. 256K MP2 is fine.
Currently online streaming is higher quality than DAB. Current DAB suits a 2" loudspeaker. With enough TX and Muxs so as to have coverage and Quality DAB could be OK. DAB currently is a waste of spectrum and electricity.
Re: Blowing air
Far more people are always affected and object than the number that complain officially.
Besides will the BBC tell honestly how many complain? Will they have a dedicated freephone number advertised in the local "freeish" papers, A clear link on website with Form. a dedicated email address etc?
Will there be a well publicised consultation.
Or is the procedure and information gathering designed to give the answer they want?
Answers on back of a stamp.
Re: What about Long Wave?
I heard the BBC had reduced R4 LW power by half.
I know it has been much worse at dawn and dusk than it was and there is interference more often. But is this the season, more chargers or the BBC reducing power?
There is a problem with CE mark and lack of policing:
1) The EMC limits are too high
2) They are not properly tested in terms of radiation from the house wiring
3) Radiation from Lighting wiring is worse as often it's loops, not "Twin and earth"
4) It's self certified, so often the product doesn't really meet CE
5) The capacitors in CFL /LED lamps "dry out" with age and the interference rises due to heat from lamp
6) Powerline/Homeplug adaptors are not realistically tested. All basically would fail CE if "real life" testing used.
7) Individual models of TV or charger can lack filter components (deliberately or accidentally), but neighbour has no idea why the Radio is poor or who to complain to.
8) Ofcom (and Comreg in Ireland) are trying/have offloaded Spectrum protection/complains to others and it's nearly impossible to get them to investigate. Even though it's one of their primary roles and ordinary Domestic reception is protected by Wireless Telegraphy Acts, EMC directives signed into law, EU and International Treaty.
You have no "absolute" right to have a newspaper delivered every day. You do have an Internationally agreed right to receive Broadcast without jamming, even from another country if it's not on a frequency allocated to your more local national transmitter.

Re: Then there is Radio 5: Mobile?
Actually if you are streaming at 100kbps approx (can be more or less) then one mast can reliably manage about 30 to 90 connections at best. It's not actually possible at all as there are only usually 3 sets of 3 channels and so the masts would interfere if more than about 20 (generously). Can't see how you can have more than 2,000 users no matter how much money you throw at Mobile.
FM level of coverage needs about x6 as many DAB TX. AM level of coverage maybe x20 (lots of small fill in due to it being 200MHz Band III)
DAB vs AM/FM
Lots of places need the "Whip" up for FM. The AM is convenient and gives coverage to small number of places not reached by AM.
1) Old AM Valve Portable Radio using replicated battery packs: 60 to 400 hours and 6p to 12p per hour depending on model. The 1953 to 1960 models only used 25mA @ 1.4V per filament and 6.5mA to 9mA HT depending on model
2) Decent 1965 to 2000+ AM/FM portable transistor or IC set: 60 to 250 hours and typically 1p to 8p per hour depending on Model and loudness.
3) DAB sets : 4 hours (4 x AA some current models) to allegedly 120 (latest Roberts using expensive Alkaline D cells) 5p to 75p per hour. (Lower price assuming cheap supermarket Alkaline, not Energizer/Duracell/Panasonic and Roberts are truthful about consumption).
Re: Great News
I bought a pair of SD cards in Tesco marked to 1/2 price for this purpose. I must find them
RiscOS was ARM Archimedes, not the 6502 based BBC Micro
It just happened to have the similar BASIC.
A newer OS than UNIX/Linux :-)
1987 vs 1976?
Ireland has a load of eVoting machines for sale.
One suggestion was to sell them to Irish Themed pubs abroad.

You need to be seriously deluded by the Reality Distortion Field to pay what this costs.
It's for people with more money than sense.
