Amen. I would love to be able to use QoS markings on incoming packets in my own network. I suspect though that my ISP wouldn't be too keen on acting on QoS marks I send them. It's just too easy to game.

Re: because you can't enjoy yourself without a drink?
It's OK the guvmint saying "don't drink to excess". However the latest value of 'excess' is patently stupid. In any case, it's hardly likely to be effective advice to people who value the feeling of being legless despite the morning-after effects.
Bravo sir! However it'll take more than a few bob to do that. Perhaps if you could persuade the moneybags that it would cure Gerbil Worming then you'll have far more money than you know what to do with.
Re: Leap Seconds
This is why there is so much pressure to kill off leap seconds. The ITU recently kicked that can down the road for another few years, but personally, I don't see why this is still such a problem. We've had leap seconds for decades and computer time protocols have been designed to signal future leap seconds for a *long* time. It does involve the strange concept of a specific minute at the end of June or December should have 61 secs. The specs also allow for 59 secs too but that is unlikely now ever to happen.
You could write the software to deal with a step, but Google decided to just slow down the computer notion of the time in a controlled fashion for several hours so that after the leap second actually occurs the clocks are exactly back in sync. That is probably much more friendly to existing applications.
Re: Let me get this straight
I suppose they could localise a version of their machine for the US- and have a separate- far more useful- far more power version- with extra channels and power- for the rest of the world
It's a bit more subtle than that. The US power limits are higher than most other countries - 30dBm on 2.4GHz versus 20dBm in the UK. However they haven't got the top 10MHz of the band that we have. There is much more variation though in allowed frequency ranges in the 5GHz band across the world, and this is probably what gets the FCC's knickers in a twist.
It's one thing, though, to set regulatory limits. It's entirely another thing whether the radio hardware will actually produce the allowed power. Probably kit designed as APs will, but that will not necessarily be the case for clients such as laptops.
Re: We didn't run out of ipv4
Don't get me wrong, getting rid of NAT is good, and I operate an ipv6-only website which really helps to keep the peasant scum out.
True, for a while. I've just looked at my firewall logs going back about 3 weeks. In that time I've had about 40k v4 'door knockers' that my firewall dropped. The v6 equivalent is essentially zero except for a few odd probes from pnap.net which look like attempts to measure performance. This is on a home network prefix with no outward-facing servers. That won't last but I think we have a few years before it gets bad.
Re: And what about BT and Virgin?
Some of the smaller ISPs have been at 100% deployment for a couple of years now. AAISP have as has IDNet.
I used to be with an Entanet reseller years ago, and got connected to Entanet's experimental service, and then after a hiatus, to their main service (on a different prefix). However that eventually failed when some lash-up kit they used for connections via BT 20C networks failed. I got fed up of waiting for them to fix it & moved to AAISP a couple of years ago. I very occasionally see v6 outages - there was one yesterday for a while - which I notice when, particularly, fonts.googleapis.com hangs (lots of websites seem to use this).
Naturally I'm all dual-stack here for all my hosts except for backward vendors such as the TV kit. It would be good to go v6 only but that needs a 6-to-4 proxy service somewhere for all the v4-only services out there that will never die, and I can't do it until all the v4-only kit here goes to recycling.
Re: It's a start
It is for autonomous and continuous craft.
I'll sorta buy that. It's more likely that a uav (hence no need for pilot safety & life support stuff) could be engineered within current & <10yr future constraints. That's OK for mapping/surveillance but wifi/tv transmitters will rapidly eat into the power budget. There is still the issue of energy to manufacture solar cells (and batteries) but that's the price to pay if the business benefits outweigh that.
No, it's not
It's a dead end. The air transport industry we currently have only works through a combination of the energy density of kerosene, the efficiency of jet engines at the end of a nearly 80 year development cycle, and similar improvements in the application of aerodynamic design.
Electric aircraft have to replicate that. They will benefit from the aerodynamic advances, but we must be getting reasonably asymptotic on that. Energy will still need to be stored as we can probably only expect a factor of 2 or 3 improvement in solar cell energy conversion and we fly at night. So we need a big step in battery energy density. Plus either an incredibly fast charge process (2 nuclear power stations at Heathrow), or a quick battery swap-out process and a slower recharge (1 nuclear power station at Heathrow)
Then how do we make an 'electric jet engine'? I guess the technique would be to replace the jet core in a high-bypass turbofan (e.g. Trent 900) with a similarly specified electric motor (about 56 MW at takeoff).
Stick with the kero & manufacture it from CO2, H2O and nuclear energy when the oil & gas runs out.
Order of magnitude errors
There are a few in this, and even on a cursory re-reading of the article, the author should have spotted them. I'm sure the aggregate pipework from Europe to Rest of World is more than 131kbits/sec!
Re: All for doing away with meter reader
If 'phone home with an accurate reading' was all it was designed to do then there would be a lot less resistance. However the subtext is 'demand management' i.e. cut you off, or perhaps a bit more cleverly, temporarily switch of some appliances. That is, or should be, a no-no. I've no problem with improving energy efficiency as long as it's done in an economically realistic way (no stupid restrictions on kettle consumption). But however good or bad the energy efficiency of our appliances is, in the rich, civilised country that we apparently are, then the energy infrastructure should be robust enough to cope with the demands placed upon it both now and in the future.
At least it still has some English(ish) words, though the syntax grates. The way Unicode is going this kind of 'communication' will just be a string of random emojis soon.
Same rubbish with Netgear
I bought a Netgear wifi extender, and the setup process went through a similar DNS name. Once I worked out what was going on, the wifi extender had got a DHCP address in my network and somehow my browser got redirected to that. Anyway, now it has a fixed address in my network and after updating the firmware there's a rule in my firewall to block outgoing connects from that address.
It also has a local name in my network but for a while, trying to use that in the browser gave me a bunch of 404s so I had to use its IP address. However that now seems to have corrected itself.
At least, though, it has a web config interface. A cheap TP-Link managed switch I bought had no web config. It used a config app that only runs under Windows:((
That's what I thought, more of our taxes spent on some useless tosser who will be dangerous because he/she has to justify their existence and build an empire.
An 'after' poll could show an enormous swing to 'Remain', but that would not change the result either. The result is what happened on June 23rd, for better or for worse.

Re: Poor science
It's true that the gravitational radiation has only been measured by one method, and that more independent methods would be good. However the character of the signals received corresponds with high accuracy to the expected character of gravitational radiation from that scenario and also matches what General Relativity would predict. In fact, the results validate GR in an extreme gravity regime that can't really be measured by other methods. If only Einstein were alive to see it!
Just use a browser anyway, its SSL handling is 100 times more secure than a banking app
Citation? The Barclays banking app uses SSL with a cert chain similar to a browser one. I can't comment on the relative security properties of the app vs browser.
Re: Dear Oracle
Having read the judgement, it looks very much like Judge Alsup has given Oracle very little wiggle room to argue on when/if they appeal this. They can only now appeal on the issue of judgement as to law versus a jury verdict on the facts, and Alsup has taken great pains to explain why it's all down to issues of fact that a jury has to decide rather than a plain direction by the law.
I'm still surprised that the appeals court threw out the verdict that the API was not copyrightable. We've all assumed that APIs were free to use and this was a bit of a shock. Perhaps now APIs should come with a 'free to use' licence and those that don't (unless in very specialised areas), fall by the wayside.
Re: I'm in two minds about this...
I'm in the 'sod them' camp. They've had plenty of time to register to vote, and there is a legally defined registration limit whatever the quality of the online registration process. I'm a bit more sympathetic to voting after the 10pm limit on polling day, if you have already joined the queue before 10pm.
As already pointed out, the regs are there for a good safety reason. I used to have a PPL (long ago) and I knew I was only safe to fly under good weather conditions. If people are paying you its harder to say "no, we have to turn back, the weather is clamping". It was drilled into us that the issue of payment for taking your friends up for a joyride was a difficult issue. Apparently one way was to bet your passenger X amount that you could return him safely, so he would pay up on landing. Supposedly a bet got around CAA rules but I'm not sure I believe that.
Well, Divine Right of Kings & all that, & given his nationality, I guess we have to appeal to Jupiter...
Rocket scientist attrition rate
Given the SOP over there for the price of failure, I wonder if they'll get a successful test before all the techs who might conceivably pull it off are banged up or executed (by ack-ack).
Re: ISIS routing protocol?
One of the rare bits of the OSI stuff from way back that has survived. It's short for 'Intermediate System to Intermediate System'. Someone I talked to about this stuff many moons ago mused on Ancient Egyptian deities instead.
Radio spectrum at the useful frequencies is a finite resource, even with some of the clever coding and MIMO stuff that's in development. Within a fibre the available spectrum is orders of magnitude greater, so in the longer term, as data rate requirements grow, fibre will be essential, not just in the backbone as it mostly is now.
It would be better if the comms infrastructure were classified more like roads & rail from a state aid perspective. I hesitate so suggest the network should be in public ownership as we would be likely back to the old days of "you'll get what you're given", but if the govt can spend all that taxpayers cash on HS2 without issues with Brussels, then why not also on a fibre broadband infrastructure at the network edges?
Incidentally, where I live in a country village, I really do have to have what I'm given - no-one other than BT would look at provision locally and it's looking increasingly unlikely that we'll get a fibre cab close by, even with BDUK cash. Gigaclear would probably not consider it either, having looked at their website & the conditions they require.
Probably not. AV has to get in very early to check when USB sticks are inserted, or incoming data gets stored. So it'll be a high priority thread. Obviously a background file scan could be lower priority, but the AV may well be arrogant enough not to bother.

Re: So all consumer grade routers are shit.....
Cisco 1801s are fairly readily available on eBay. Alternatively, roll your own with an embedded Linux distro - e.g. LEAF/Bering - or go BSD with pfsense, on various hardware platforms. Of course all these have a learning curve - none of them are really plug 'n play. If you already know Cisco IOS then an 1801 is easy. Pfsense and some of the specific router/firewall Linux distros are fairly easy to configure too though you need to choose a hardware platform.
Well, he's a politician, and like the overwhelming majority of that breed, he knows eff all about nearly everything. You would think that ministers would do a bit of homework on their brief. I suspect, though, that none of the civil servants from whom he would deign to gather advice know anything about the subject either.
I would be seriously pissed off if anyone seriously offered me Internet over VSAT as a service. I might be glad of it in the middle of Mali or Botswana but not anywhere in the UK.

Web? 1993? It was all Gopher and downloaded software by e-mail from DEC's ftpmail server. Tim Berners-Lee was still unknown. Usenet was in its prime, and who could forget the AA BBS...
Well, the single track working problem was solved well over a century ago with the token system. Originally physical, with end-to-end interlocks between the token dispensers in the signal boxes, it's now often done electronically. No reason why they can't do that over satellites. That's what makes me so surprised about that head-on crash on a single track in Germany a few weeks ago.
I wondered about that, but 100M multidrop is probably hard. It's much more likely that there will be a few point-to-point 100M connections to strategically placed hubs & CAN from then on to the light clusters.
Key Stage 2
Is this now the target audience? Or are we now to assume that the average software guy has zero exposure to basic electronics?
KS2 in UK is around 4th or 5th Grade in US, I think.
Re: Panasonic: Sony's younger idiot brother
Yup. I've got a 2010 model Panny TV, and it recently stopped working on ITV-HD via satellite when ITV changed a parameter of the satellite signal (still within the DVB spec). I've had e-mail discussions with P about a s/w update but the probability of that is infinitesimally greater than zero. P stopped updating the s/w about a year after I bought it, and virtually all the 'smart TV' services on there at the time are now gone. My next TV won't be Panasonic!
I've recently bought a Samsung Blu-Ray player and that phones home to Korea all the time to find out what to do. It works a treat now but I wonder how long for.
Re: Another white flag is raised
A letterbox sized screen is not ideal for reading books which, lets face it are more suited to a 4:3 screen ratio
Well, the first bit is true, but all the books I usually read have a portrait aspect ratio. The usual small size paperbacks in the UK are 198x128mm - an aspect ratio of ~3:2 in portrait. So you just turn the tablet on its side?
As for Nook, I bought one of these in preference to a Kindle as it could read a wider range of e-book file formats. I suppose I half expected some problems further down the line - the history of DRM content is littered with content lock-outs due to businesses going bust or getting out of the market. Perhaps B&N don't want to pay the publishers to licence content for the UK. I shall be royally pissed off though if any of the books I currently have get wiped by Sainsbury's because they haven't licensed it.
Be careful what you wish for
As always. Just to be sexist for a minute, is the lack of women in tech down to us cavemen putting them off, or are they just not interested & enthused by the subject?
I was down at the computing museum at BP last year, looking at the Harwell Dekatron computer. There was a school party there with quite a few girls, and the presenter, as a form of encouragement, was showing them pics of the early days with quite a few women in the team. In those days a lot of programming was writing code on sheets marked off into boxes with one character per box so that punch card operators could punch it up into a card deck. I did wonder whether the women were designing the algorithms or just writing the code on the sheets. In those days, 'writing code on sheets' was seen as a perfectly reasonable job for a woman, and they may well have seen it that way too, as just another sort of clerical function. These days that just doesn't wash, so girls generally don't want to do that stuff, and I wonder just how many of them really are enthused by the process of algorithm design as a prelude to the process of writing code.

Far too many acronyms

Re: David Cameron... ... is starting to piss me off now.

At least it's our unreformed wholly rotten organisation, so we've got slightly more chance of reforming it than we have of reforming that thing in Brussels.
Re: Asus is Asus... it's not Cisco, Aruba, Meru, etc...
Hmm. A Windows-based router doesn't fill me with a lot of confidence but I see where you are coming from. However, although Microsoft's security processes are now quite good (though they misuse it regularly for other purposes), it took them a long time and a lot of mis-steps in the past to get there. It's also not cheap for them to manage, but only a small cost now compared with their revenue.
The same doesn't apply in the router market. One could argue that the fact that the big ISPs bundle a router with the product militates against good router security, as the ISPs demand a 'just good enough' product at a rock-bottom price. So the other manufacturers have to follow the race to the bottom to compete. Of the router mfrs, only the big iron guys like Cisco could support a MS-style security wrap and Cisco aren't really in the consumer market.
The later BT home hubs seem to have a good customer-based security wrap - a little slide-in card in the back with random Wifi and admin passwords. Let's hope the internal security config is as well thought out.
Re: To be clear
As the article states, the key to the data (128 bits, 256 bits?) is buried in the CPU, and the CPU will only use it itself to decrypt data on presentation of a valid passcode. So even though the flash memory could be cloned, that is useless without the key, which stays buried in the CPU at all times. So you need both the memory and that particular CPU running valid code to be able to get at the data.
Re: thermonuclear FORTRAN
The electromagnetic field modelling package NEC2 is a bit like this, though one part of the user manual does try to explain things. It uses magic numbers, particularly a high value (10,000) added to the segment number. Guess what happens when you have more than 9999 segments in a model...
Of course the code was written in the days when a 9999 segment model would a) take far more memory than the computers in those days could handle and b) take longer than the age of the universe to run.
Nowadays it's still used a lot by radio amateurs to model antennas so we run into these limits (amongst others in this package). I have hacked it to model up to 30k segments on Linux, but beyond that it runs into yet another, more fundamental limit.
Re: 5.30 Friday is worse
You mean you actually accepted those meeting invites?
They weren't optional, and in those days it was all face-to-face. I was just a peon team leader at the time. Thankfully that project just kinda wasted away & I moved onto some more interesting stuff with a better management ethos (stayed out of my hair!).
5.30 Friday is worse
The project manager on a big project I was working on used to do that. OK I suppose if you retire to the pub after, but that was not my scene. Friday evening in the pub is for a nice wind-down with some friends after tea at home with the family, not a work colleagues piss-up.
Re: Is it a test?
I doubt they would open the envelope in front of the world, and with the paper already printed in Nature, just to find "that was a test". I suspect the envelope-opening ceremony happened in private at a LIGO meeting some weeks ago, given the time that rumours have been circulating.
At the time he wrote that, the Internet was very much smaller & most people on it were geeks of one sort or another. So it was not exactly a dumb statement then. However AOL was connected about that time & the 'net started a long descent to what we see today, though there have been compensations along the way (Altavista & descendants, http, etc). PGP has always required some intelligent deployment. Enigmail might be just a plug-in but the real work is setting up & managing the public key infrastructure required to use it effectively as a day-to-day tool. Amongst a small circle of friends, acquaintances & colleagues that is manageable, but otherwise, forget it. And although there is now a halfway decent CA infrastructure for website certificates, that's still too hard to deploy universally for personal e-mail signing & encryption.
So non-TLS encryption is going to stick out like a sore thumb for a long long time, even TLS used in unusual contexts (not web, not IMAP etc).
Have Apple actually done wrong here? They were offered a deal by the Belgian govt, which the EU have now said is illegal state aid. So if anything it's the Belgian govt which is in the wrong. Apple can easily say they accepted the offer in good faith. No doubt the devil is in the details though.
