Most online video services will automatically change resoloution and/or compression level based on detected throughput. So simply throttling traffic to/from known video distribution servers should be sufficient.

The goal is almost certainly not to catch every single video. It's to drive down the average usage per user.

Traditionally transistors are made by doping the surface of a silion wafer. The interconnect is then built on top by laying down alternate layers of oxide and either metal or polysilicon. So while you get multiple layers of interconnect you only get one layer of transistors.

"3D" ICs aim to have not just multiple layers of interconnect but also multiple layers of transistors.

Currently IANA has already allocated a number of /16 blocks to the RIRs

Actually they allocated them /12s . There are also some smaller older allocations. So currently less than 6 /12s of global unicast space have been allocated.

Currently IANA has already allocated a number of /16 blocks to the RIRs, and it's up to them to allocate it as they wish. While ARIN has been assigning blocks like birdseed (the way Jon Postel did in the early days of IPv4) downstream in /48s, RIPE and APNIC have been more conservative, and assigning them in /56 blocks.

The standard allocation for an ISP is generally a /32, they then suballocate to customers in smaller chunks (/56 is currently considered best practice as a default allocation for small customers).

The way address exhaustion is likely to occur is not distribution (for obvious reasons) but rather, lending structure to those addresses. While route optimization seems to have been abandoned for now

Mainly because the Internet is NOT a network with a strict and static heirachy, it's a network of private companies involved in constantly shifting relationships.

Like let's say Acme, Inc has 2001:db8:beef:1a00::/56.

If Acme is as big as your next sentances imply they should have no trouble getting at least a /48.

Messy internal routing due to poor initial layout may be a slight issue but I would expect it to be much less of a problem with IPv6 than with IPv4.

The other option would be to subnet even further to /80 or /96, at which point, one is breaking some IPv6 protocols like SLAAC, ND

AIUI the actual neighbour solicitation/advertisement parts of ND are independent of subnet size.

SLAAC is indeed broken by nonstandard subnet sizes but DHCPv6 can be used instead.

insanity like the Cogent-v-Hurricane split of the IPv6 internet (holy crud... it's SEVEN years now since Hurricane baked Cogent that cake begging them to peer with the world's largest IPv6 network... and it's still broken),

It's irritating that those companies care more about interconnection politics than about serving their customers but I don't think it's that important in the grand scheme of things. Decent hosting providers are usually multihomed and thus reachable from both HE and Cogent.

I'm prettys sure you are wrong,

My memory says that the keys used to sign the shims are only valid for x86 systems, not windows RT systems. I can't seem to find a good source for that now though I did find a mention in passing in https://msdn.microsoft.com/en-... . Furthermore everything I can find relating to linux on the surface RT relates to a recently found bug.

AIUI the arm based surface tablets (surface RT and surface 2) are locked down to the hilt with forced secure boot that will only boot windows

OTOH the x86 based ones (surface pro, surface pro 2, surface 3, surface pro 3) can have secure boot disabled.

That depends on where you live and how much you are prepared to pay.

Afaict in most urban areas BT openreach "broadband" services top out at "up to 80Mbps" FTCC. In a few trial areas they have "up to 120Mbps" FTTC or "up to 330Mbps" FTTP.

There was supposed to be a product called FTTPoD which would allow people in FTTC areas to get FTTP if they paid a steep (usually thousands of pounds iirc) installation charge but new installations under that program have been suspended.

Virgin media are offering a 200Mbps cable package for home broadband customers and a 300Mbps cable package for buisness broadband customers.

If you move beyond the "broadband" products to the dedicated fiber products then it becomes a matter of how much you are prepared to pay.

Comment Re: Why do people think self driving cars will cat (Score 1) 622

Plenty of people in cities get by on public transport, and it's generally quicker in a lot of major cities.

That depends very much on when and where you are travelling. The practicality of public transport also depends on what you want to take with you.

If you live in the city center of a major city then public transport is good so you rarely need a car. Plus keeping a car in the city center is expensive. For these people Public transport takes the bulk and Taxis and/or car share services cover the minority of journeys where public transport is unsuitable. Obviously poorer people will have more of a bias towards public transport while richer people will be more likely to use the Taxi and car share services where conviniant.

Out in the suburbs public transport coverage is worse, car share services (at least where I live) are practically non-existant and the distances involved make taxi's an expensive option. For many people this shifts the balance towards owning a car. Especially for people who have already paid the upfront costs of starting to drive.

If/when self driving cars are able (both legally and technically) to operate unsupervised I would expect this balance to shift. The driver represents a large propotion of the operating costs of a taxi.

Clarkson got fired after hitting a producer effectively ending the series in progress. There was a farewell episode some time after the incident which IIRC used already-recorded location footage, studio footage with just Hammond and May.and a voiceover recorded by clarkson. Hammond and May also left the show out of solidarity with Clarkson. The trio went to Amazon where they have been working on a new car show (which has not been released yet so it's yet to be seen how succesful it will be).

Meanwhile the BBC who still own the "TOP Gear" trademarks, distribution contracts etc started casting up a new iteration of the show. The first series of this aired recently to dissapointing ratings.

Comment Re:rule changes (Score 1) 165

but no amount of computing power would give them the ability to change the rules (because cryptography).

That depends.

If you have more than half the hashing power then you can unilaterally make the rules tighter. Blocks contining transactions that do not satisfy your rules will not be used as a base to mine on by your miners and so will be quickly forked off. For example you could require a transaction fee of a minimum percentage of the transaction value or you could require that all bitcoin addresses were registered in a govrnment database.

On the other hand you cannot unilaterally make the rules looser without forking the network.

Comment Re:Has IPv6's reputation just been destroyed? (Score 1) 229

So you believe they're buying routers and switches that can't do ipv6, rather than that they simply haven't changed a config file to turn it on for the end user?

As I understand it reality is somewhere between those two extremes.

Afaict pushing out IPv6 consists of

1. Making sure the hardware and software in your network (including CPE if you provide it) *really* supports it, not just has a checkbox on the feature list for "IPv6" but can handle IPv6 with comparable features, performance and reliability to IPv4. Some hardware can have a long lifecycle so this can take a while.
2. Coming up with a plan for allocating addresses and distributing addresses to customers and routes to routers. Since NAT is strongly discouraged you need to have a system that hands out not just individual addresses but blocks and that tells your routers which customer has which block.
3. Training all your suppport and admin staff on IPv6.
4. Running limited trials to make sure you actually did 1-3 successfully and you can turn it on without breaking things and causing a massive support load.
5. Actually pushing it out.

That's doable but it's a fair bit of work. Until recently there was little motivation to do so. Now with IPv4 exhaustion actually upon us the ISPs are starting to take IPv6 more seriously.
