Brace yourselves, telcos: Ofcom triples cost of 2G spectrum holdings

Alan Brown Silver badge

When will Ofcom....

1: Think about allocating the old AMPS 800Mhz band for 2/3/4G?

2: Think about allocating the original 450MHz NMTS (The norwegian system that AMPS was based on) for the same purposes?)

Alan Brown Silver badge

several reasons

You can run 2g/3g/4g in either band if the channelling lines up (it doesn't for 4g, as noted. Allocations aren't wide enough to handle 4G so there needs to be some juggling anyway)

The issues noted are that 900MHz works better in rural environments and indoors.

This means that O2/Voda have a distinct competitive/technical advantage (noone else has these bands) at a subsidised rate, simply because they were early players. There's nothing whatsoever stopping them handing the bands back or making better ouse of them, But if they don't pay for them why would they bother?

It is, up to a threshold (much higher than in the USA).

Brit inventor Dyson challenges EU ruling on his hoover's energy efficiency ratings

Alan Brown Silver badge

Re: Dyson have a point.

"Someone must define a 'standard carpet' with an exact laboratory-standard mixture of dust particles of various sizes and a measured quantity of cat hair."

FWIW, they have. The issue is that testing takes place once, with a new device and there isn't enough material tested to actually fill a container/bag - so all that's being measure is initial efficiency - which to be frank, is crap on all of them.

Some time back a british gentleman managed to patent a system where the exhaust air is redierected down onto the carpet/floor just in front of the suction head. The result was that the same cleaning efficiency can be achived with about 25% of the power(*). As far as I'm aware there is only ONE cleaner on the market which makes use of this innovation.

(*) It also means that the fine dust spray which all vacuum cleaners emit (even the HEPA filtered ones) is eliminated and efficiency sapping fine filtration is largely unncessary because with the air being recirculated continuously the filters have a much greater chance of catching everything.

TWELFTH-CENTURY TARDIS turns up in Ethiopia

Re: So, how many still missing ?

A lot of the "not lost" ones are edited to hell and back thanks to syndication (stations would cut film to fit adverts and drop the ends on the floor). Finding another archive helps piece together the originals.

The same phenomenon was noticed with Star Trek TOS. Entire scenes were found to have been chopped out to make eps fit into advertising schedules (syndicated series are passed from station to station) and restoring them from the canonical archives (which someone at paramount had the sense to preserve) during the 1980-90s made things make a lot more sense.

"No, I mean thieves. If a book/film/whatever is on sale at £10 and you steal it; you just stopped the creators getting their cut of that £10. If you copy it - it's the same thing. (And I'll type this slowly so that you can keep up). THE. CREATOR. DOES. NOT. GET. PAID."

If I sell or give a boook/film away the creator doesn't get paid either.

Which is why there have been attempts to shut down the secondhand book and music markets (That's where the First Sale doctrine comes from).

Exciting MIT droplet discovery could turbocharge power plants, airships and more

Alan Brown Silver badge

Re: Nothing will make airships viable.

The formula for burning involves combining hydrogen from the fuel with Oxygen and Carbon from the fuel with oxygen.

The Co2 is lost, but the H20 is retained. As long as you can get close to the magic "1 gallon of diesel gives 1 gallon of water" you can make up the rest by putting a compressor onboard and using that to pull helium in/out of the gasbags. (Even if it doesn't get that close, it makes the compressor's load easier provided the weight penalty isn't too high

Given the size of these aircraft, I do wonder a bit whether enough emergency lift can be generated to prevent microbursts downing the things (That's what took out most of the airships. Weather radar wasn't around back then. Piss poor designs like the R101 didn't help either)

You're about 200 years late with that idea and the problem remains the same now as it was then.

Re: Nothing will make airships viable.

"The hydrogen only went up AFTER the rocket fuel coated outer canvas cover set on fire and the fire then burned through the gas bags."

That trope has been pretty much debunked. Research on the paint used along with chunks of the surviving fabric showed that while it would burn if provoked, it was self extinguishing almost immediately whnen removed from a heat source. The only way it could have burned as seen in the newsreel is if something was keeping it going from the inside.

Indeed, if the skin had been as flammable as claimed. there wouldn't have been millions of unburned fragments of it falling to the ground - it would have all burned up before it got there.

Hydrogen burns with an almost invisible flame and it's conjectured that with the brightness of the burning fabric (lit and sustained by hydrogen flames) quite effectively masked the burning hydrogen. Some substances emit pretty bright light in a hydrogen flame too - limelight springs to mind.

Re: Nothing will make airships viable.

"And why not use hydrogen - we should be able to make it workable now."

Gaseous hydrogen messes up just about everything it's in long-term contact with. Metals go brittle, but so do most things you'd think of as suitable envelope material (rubber, plastics, etc etc)

Explosion predicted in Myanmar's mobe and slab markets - analysts

Alan Brown Silver badge

Device prices have little to do with it.

Context: The average Burmese citizen earns about $5/day

Network SIMs were (and are) heavily government controlled and used to be upwards of US$1000 apiece to buy, plus operating charges.

New, very cheap (about $2) SIMs were introduced at the start of the year but these are for the CDMA network operated by the Army, are extremely limited in supply (ballots among villages are usually oversubscribed by more than 20:1) and of course won't work in GSM phones.

Myanmar/Burma has competing GSM and CDMA networks.

GSM SIM prices have come down a lot since the start of the year but they are also in very short supply. You can wait 6-8 months for one at the official $1.50 rate or buy on the black market at the prevailing rate of about $80

Phones are getting a lot cheaper (they used to be extremely heavily taxed at the border) but the real barrier to entry has been high startup/operating costs and the reduction in those prices is what's driving sales at the moment.

Things will change further over the next year as several companies are rolling out new GSM networks. I'm aware of 2 companies actively recruiting people with turnkey installation experience right now and another 2 seeking staff for the management side.

@Stilted Banker: The Burma/Myanmar name issue is complex. You will find that both names are used inside the country and a lot of people do not like the name change, feeling the military oligarchy had no right to impose it on the people without consultation. Others just want to move forward and make up for 60 years of stagnation. Given there are still 3 civil wars going on in different parts of the country it's hard to run a referendum and get consensus.

Re: some good points...

"DC would be great even in homes"

No, it wouldn't.

Why? Safety. Amongst other things one of the great advantages of AC is that any arc generated is extinguished every 20mS. DC allows self-sustaining arcs.

A long time ago I read a story about the old 300VDC distribution system in Sydney and one of the recollections published was of a light bulb burning out.

"The arc which formed as the filiament parted burned its way up the support wires in the bulb, through the base, bulbholder and was most of the way up the power lead to the ceiling rose before someone managed to hit the off switch"

Arc suppression is also the reason why a switch rated at 10A AC has to be derated to 3A for DC operation.

HV DC distribution in homes would result in more fires and fatal electrocutions (Muscles hit with DC never relax, AC is more like a series of hammer blows).

HTDC is great for distribution and now we have the technology for stepping voltages efficiently and without requiring several acres of space there are good arguments for using it right down to 11kv level, but DC in the home/premises requires a complete overhaul of local distribution, house wiring and appliances safety margins.

@ AC 25/9 11:57

All the stuff you're ranting about was originally on the design plans and were trashed in the 1970s due to environmental and political objections. The M25 itself is an amalgamation of ring3 and 4 (which is why it goes to a greater radius road around watford and why there is a section of motorway-class road just north of the M25 between the M11 and the A1

I suggest you acquaint yourself with the history of the London Ringway plan.

It's not just the addressbook harvesting.

LinkedIn reps have shown up on several spamfighting lists and have usually departed quickly when the level of anger over their practices becomes apparent.

There's a very special pit in Hades reserved for the LinkedIn execs.

Re: Think of the children

I doubt it's illegal immigrants. They can't get these kinds of jobs given the level of checking going on.

Having someone else sign on for you is the main issue ISS are trying to combat (it's rife in a lot of industries and it's possible that someone legit may then hand over their ID to a 3rd party for "nefarious" or other purposes (sub-sub-contracting?)). Using something they can't handoff to someone else is a logical step (Although palm scanners work better - fingerprints can be cloned off onto a latex glove.)

Added to fear of being caught fiddling their hours, the other fear for some cleaners is being caught fiddling on benefits - but then again most such fiddling is under-the-table anyway.
