A short IPv6 story
A little while ago, we leased a new dedicated server for our business. In the spirit of keeping up with technology and looking to the future, I got one that had ipv6 connectivity.
Shortly after migrating to this new server I was made aware that an application that uses Google Cloud Messaging was no longer working properly, Google was reporting that the server was unauthorised to send out messages. I checked everything and couldn't see the problem, the code was exactly the same as running on the older server and the new ipv4 address had been entered correctly into the Google control panel.
Only after days of digging did the cause of the problem come to light. The cURL library used to send out messages was automatically defaulting to ipv6 rather than ipv4 and so Google was rejecting the messages since the ipv6 address wasn't authorised. Fine - I'd just enter that into the Google control panel then... but wait, what's this? Google's control panel only accepts ipv4 addresses...
Long story short - I disabled ipv6 on the new server as the simplest solution with the added benefit that no more stuff would break for no apparent reason.
Are we sure it's a selfie???
It doesn't look like a selfie to me - the monkey doesn't have his arm out towards the camera!
Bit weird to divert to Gatwick though - in flight terms Edinburgh is what, 15 minutes further away?
In terms of technology, Google are possibly way ahead of Amazon and Microsoft, simply because of what they have developed to run their own applications.
Microsoft would be the one I'd put a distant third in this race.
Re: IPv6 is flawed
Agreed - and there's no incentive for ipv6 takeup at the consumer level because NAT is so good at its job.
It's not like ipv6 is the equivalent of colour telly over b&w, to the average consumer ipv6 offers no benefits just potential headaches.
Re: World Domination
Every aspiring James Bond villain knows you haven't arrived until you have a rogue satellite fleet at your disposal - well, that and an underground lair and a private army.
It's IPv6 that should die
It was ill-conceived right from the start - by not being an expansion of IPv4 but a replacement. It doesn't matter that my computers are capable of IPv6 if my ISP-supplied router isn't
It's worth reading The IPv6 Mess by DJ Bernstein - http://cr.yp.to/djbdns/ipv6mess.html - that paper was written over 10 years ago now, but all the criticisms of IPv6 are as valid today as they were then. But nothing has been done and thus we have the mess we're in now - where IPv6 is the bastard child that the masses don't care about.
Re: Here is an idea
"Free markets have made you, and billions of people all over the world considerably richer."
Bollocks - this is a fallacy frequently peddled to try to preserve the status quo. Although as you rightly point out, there are very few truly 'free' markets in the world economy.
The wealth gap between rich and poor is now bigger than it's ever been and "The 85 Richest People In The World Have As Much Wealth As The 3.5 Billion Poorest" (source: http://www.forbes.com/sites/laurashin/2014/01/23/the-85-richest-people-in-the-world-have-as-much-wealth-as-the-3-5-billion-poorest/ )
Real wealth is created through effort and invention (and the wholesale exploitation of the world's limited natural resources, but that's another discussion), not by mindless and parasitic behaviour in the financial markets. That is all geared to trying to get rich by taking wealth away from other people and institutions.
Much easier way
If you keep your old, legitimate copy of XP on a separate hard drive when you install Windows 7 you can either then just set up your machine to dual boot so you can run XP when you need it OR using Virtualbox you can create a VM that attaches to the old physical XP disk (as a raw disk) and boots from there. No need to re-install XP, fiddle with any licence or reinstall any apps, your XP machine lives again :)
The only wrinkle if you use the 2nd method is that you must make sure that the XP disk is 'offline' as far as Windows 7 is concerned but is available read/write to the VM while using the VM. You do this using the DISKPART utility from the command line in Windows 7
SELECT DISK 1 (where this number is the window 7's logical disk number for the XP drive)
ATTRIBUTES DISK CLEAR READONLY
Do that BEFORE starting the XP virtual machine. You also may need to change the graphic driver for XP running under the VM since it no longer has direct access to the graphics card (depends on your original setup).
At least with open source, once the bug has been discovered:
1) we can properly understand the problem and its implications
2) a patch can be made in timely fashion (my servers running Debian Wheezy already have a patch).
Meanwhile for Microshaft and Adobe bugs we have to rely on their tardy release notes and patches for information and fixes or alternatively reverse engineer stuff (breaking their EULAs in the process).
Why mess around?
Come on, if we're going for the tech solution, everyone just gets chipped at birth, you know, like dogs. That way Big Brother can know who you are, where you are, whenever they want.
15% is misleading
That 15% figure for windows XP refers to desktop AND TABLET OSs, since XP doesn't run on tablets it's irrelevant. The figure for just desktop PCs is just under 30%.
Re: I believe that a well-implemented cybercurrency would be a good thing...
The weak point of Bitcoin is how people convert into/out of proper currencies. So a 'run' in this context is lots of people wanting to sell Bitcoin while few people are prepared to stump up dollars for them. If the exchanges run out of liquidity, the whole thing grinds to a halt.
Re: And yet...
The people who are really laughing all the way to the (real) bank are the US authorities that sold all their bitcoins with the market near its peak.
Just because some gullible people see a dip in the price as a chance to jump into the market having maybe missed out on the first bubble means nada. - other than providing more opportunities for the sharks. Come back here in six months and see what the price is then.
Love this take on it
Entertaining writeup of the whole fiasco from a bitcoinista here:
It's not like this came out of the blue
Mt.Gox has been a weak link in the whole Bitcoin setup for a long time, you only need to look back through the Register's archive, e.g:
and a perceptive analysis of that incident on another blog
made it clear that Mt.Gox was just an accident waiting to happen. Tulip anyone?
a) it takes care of most of the cross-browser compatibility problems
b) It's well documented and relatively bug free.
Sure I could write my own framework, but why should I re-invent the wheel?
It's quite a few years since I looked at it, but when I did it was more 'spreadsheet wars' than anything else. Screens and screens full of numbers supposedly simulating space trading and combat. Obviously appeals to some, but I found it deadly dull.
Debian systems ok
Just checked my servers and it seems the default config provided for ntpd by Debian is already safe as it includes the lines:
restrict -4 default kod notrap nomodify nopeer noquery
restrict -6 default kod notrap nomodify nopeer noquery
where the advisory advises adding 'noquery' to prevent the attack
The beginning of the end
Large sale drives down price... panics speculators... rest is history
"It's also not the case that you can't easily chop Windows down to next to nothing."
You could have a nice sideline in writing a guide as to how to do this, since it's not something that any official documentation provides.
Seized top level domains?
What you mean like .uk, .com and .gov?
"He's not the Messiah, he's a very naughty boy!"
Yep, geolocking is stupid, it's also trivial (if a little cumbersome) to bypass by using proxies. It's time the media companies realised that the internet is worldwide and their rights should be too.
They should join forces with...
... the ipv6 folks. They can't organise a switchover either.
For this to work...
doesn't it mean that Google has to be listening continuously to everything you say, otherwise how would it know when you say the magic words?
I have a 3D-TV. I only bought it because the retailer was flogging them off cheap because hardly anyone wants 3D.
The stereoscopic glasses are still in their wrapping.
Re: Never going to work
Except that that's not how "proper" currencies (something that can be used as an everyday means of exchange) work. Internal market prices/wages should NOT change in response to the external exchange rate (or at least only slowly, over time).
If you're saying that 1000 dollar exchanged into Bitcoin can always buy me 1000 dollars worth of goods, (ignoring the supposed anonimity advantages) I may as well just use the dollars in the first place and avoid the exchange costs.
Bitcoin is just a speculation investment and at the moment has all the appearance of a south-sea bubble one at that.
Never going to work
It's an interesting technical exercise but Bitcoin itself is never going to work for the masses.
The supply of new coins decreases with time, which is exactly the opposite of what you want for a stable and useful currency if you want to grow the user base, since (bubbles and crashes aside) it becomes more and more expensive for new people to start using it. But it's made the early adopters rich.
I have approximately 0.05 of a Bitcoin myself (acquired via an experiment with mining, before the kit needed became prohibitively expensive) worth at today's exchange rate around £25.
Autorun strikes again
Autorun is a stupid, stupid feature of Windows, that should never have made it into release. Whoever first thought of it must have been braindead.
Anyone interested in RISC OS should look at http://www.redsquirrel.fsnet.co.uk/redsquirrel.html a native RISCOS emulator for x86/Windows. Still have a copy of my final RISC OS machine running under it - and the nice thing is that with modern hardware it actually runs faster in the emulator than it ever did on the real hardware :)
Re: There's science and then there's wild guesswork
Actually I do know quite a bit about the subject since it's a related area to my own area of expertise.
These conclusions (indeed one could argue almost the whole of distant object astronomical science) are based on theories which cannot be proven without spacecraft being able to travel vast distances. Given that the furthest any of our craft have got so far is only just beyond our own solar system (Voyager), one erroneous assumption brings the whole theoretical house-of-cards tumbling down.
For instance a lot of what is surmised about objects in space is based on the principle of Doppler blueshift where the frequency of observed light changes as a result of the movement of a source toward the observer. We know that this is how light behaves over short distances since we can prove it under laboratory conditions. However how can we be sure that once those distances are scaled up to light-years there isn't some other factor that comes into play? Or other unknown and undetected phenomena out there in space have an effect? There is just no way we can test for it with our current level of technology. And if that theory no longer holds true then much of what is surmised about distant space is wrong. I'm not saying that particular theory is wrong, but that's just one example.
There's science and then there's wild guesswork
I love how these astrophysicists can give us the size, mass, composition and relative position of a very distant object based on a tiny, tiny scrap of electromagnetic data.
If they are baffled as to how such a planet could be where it is, the obvious answer is that their conclusions about the data are wrong.
What I want to know is...
why haven't the folks in Under The Dome figured out that they could use something like this to talk to the outside world yet?
Accumulating an $8.5bn fortune via capitalist enterprise and being genuinely left-wing are not two characteristics that often go hand-in-hand.
Gobbled up all their capital?
Forgive me if I'm being naive, but isn't a core principle of high-risk investments that you make a lot of them for a small proportion of your capital each, thus, er... spreading the, erm... risk?
For the paranoid, there are Android apps that provide this sort of functionality (and much, much more ) already - for instance see http://www.androidlost.com
Now that is for you to track your phone when it's been stolen or lost, but it's no big stretch to see an emergency services equivalent.
Genius until the first incident where a Delta aircraft gets into trouble because their Microsoft tablet locks up at just the wrong moment...

PC version is on its way
Some clever bods have already identified config files intended for the PC released with the console versions, so there can be little doubt that the PC version is coming, it's just a question of when (my money is on late Nov/ early Dec in time for Chrismas sales).
I suspect the console versions are released first these days as people with both a PC and a console would probably get the PC version as it will have better graphics. By holding back that release, they probably push up console sales and may even get some double sales to people who have both.
"What kind of dumb-ass names ultra-secretive operations with names that are anything to do with their subject matter?"
Probably the same sort of dumbass that thought this operation was a good idea in the first place.
All I want to know is...
"are you seeking entry to engage in criminal or immoral activities?"
What's the point?
How does spending god-knows-how-many millions on rebranding and splitting systems to create a separate bank actually help anyone at all? Surely all it does is drive up costs, costs which inevitably get passed on to the customers.
And no doubt in a few years time, when the newly independent TSB is struggling, it will get swallowed up again by one of the giant institutions.
Not missing much?
Given Microsoft's recent record of f**king up patches - perhaps it doesn't really matter if support is ending?
Re: "3D films are increasingly becoming the standard"
and the BBC has indefinitely suspended any 3D broadcasts meanwhile 3D-TVs are stockpiled in the warehouses.
Yep... some standard.
isn't it just easier to ask the NSA or GCHQ for copies of all the target's emails?
Shouldn't they be doing something more productive with their time like getting drunk or watching Countdown?
Not only Surface RT
The exact same analysis could be applied to Windows 8.
Microsoft has never been particularly good technically, the one thing they used to be brilliant at was marketing. Now it seems that even that skill is deserting them.
Such a sorry end
Opera have quite literally thrown away their USP for the desktop browser. Who's going to be interested in a Chrome clone when you can just run Chrome?
I had no problem with the idea of them using the Webkit rendering engine when they announced that change, but then to dump everything that made their browser stand out????
So now their sales pitch is what? Try us... we're just like Chrome only with more bugs?
Can someone explain...
the logic between the 802.11 suffixes? we've had a/b/g/n and now ac? To the layman they provide no clue as to which one is better/faster and ever since we got past 'b' seem to have been plucked out of thin (but heavily irradiated!) air...
