ARIN heads off IP address land grab

Nick

not inexhaustible

Yes there are a huge number IPv6 addresses: 10^38

But if the block size they give out is too big then it might not go as far as you'd think.

Google got 2^96 adresses. If that's going to be the going rate then they can make 4 billion allocations.

Now that's a large number but it's not what I'd call astronomical.

NAT is not the answer

@Simon Painter

But you can't route to NATed address. That means IP telephony, video conferencing, etc. becomes more tricky.

Plus there are some other reasons that I remember being told about but have since forgotten.

However autorun is a major malware vector so in a locked-down environment you won't be able to run the executable.

Exploding core counts: Heading for the buffers

Re: I don't get it

Kenny Swan wrote:

"I just don't get why some hardware can't be designed that automatically spread the load between different cores. Is it really that much of a problem to do so?"

Consider the loop:

for(i=1;i<n;i++) a[i]+=a[i-1];

Every iteration of the loop depends on the result of the previous iteration. It's very tricky to parallelize (if not impossible).

It's data dependency issues like that which bugger up your scaling. You have to take a step back and redesign your code to avoid them.

"the system had to be made from more expensive components just to accommodate the pitiful attempts to get an MS OS down to size is a waste of money."

They added an SD reader. It cost a few quid and I'm very grateful because it means that I can run Ubuntu on my XO.

Mark wrote:

"OLPC is not a computer. It is a learning device."

This is very true. The XO with Sugar interface is a very good collaborative tool for teaching.

But what it requires for this to work is local infrastructure in terms of expertise, support, teaching resources, etc. Dumping in a bunch of machines does not make an educational program. The OLPC project seems to be relying on Open Collaboration to make this magically happen. But that requires nuturing by willing and capable people on the ground before momentum takes over.

What it is not is a Web 2.0 multimedia laptop experience. If countries want to use them as laptops in the traditional sense then I don't see any problem with that.

They're struggling to get enough volume to get the cost down. If they can sell twice as many by shipping Windows then that will bring down the costs of the Linux versions.

I'm sure that Microsoft is pushing as hard as they can but that's capitalism for you.

William Old replied:

"In this particular case, the gravitational pull of the Earth *is* the centripetal force that acts on said orbiting object."

I'll admit that I was rather imprecise with my language.

However, I wouldn't say that "the gravitational pull of the Earth is the centripetal force". One is a force, the other is a requirement for the orbital motion.

If we're going to nit-pick then I would say that gravity *provides* the centripetal force.

Even in orbit the gravitational force is still significant, it's just balanced by the centripetal force. Achieving escape velocity would require a sizeable push (which will affect your orbit). And you're more likely to hit the moon or another planet than ever reach the sun.

Common usernames get more spam

Nick

Well blow me down with a feather!

When hotmail.co.uk started I jumped in quick and picked up a couple of addresses which are my name. They pick up quite a few bits of spam even though I never got round to actually using them. Initials are just as popular.

Occasionally I take a peek to see what the spam-du-jour is and I noticed that the other thing that happens is that people randomly use that address when registering things or filling out forms. I sometimes reply if a real person then gets in touch, one of whom worked at a golf club and couldn't get his head around the fact that I was the wrong person.

I own a couple of spare domains so now everyone gets their own personalized version of my email address which is of the form:

prefix.theirname.randomnumber@mydomain.com

Anything without "prefix." at the start gets "User unknown" which stops most spambots forging random From: addresses at the domain.

If I do get spam then I know who to blame and I can block that address whilst only affecting one person.

The random number removes the guessability factor if you know the prefix.

A third of Vista PCs downgraded to XP

Nick

Microsoft is laughing all the way to the bank

They're shipping with Vista so they can claim the good sales figures.

And people are buying two Microsoft operating systems instead of one.

So they're either:

Corporate customers who are already paying a shedload of money.

People buying machines with the expensive versions of Vista with the downgrade rights.

People buying machines with the cheap Vista and then buying XP.

Kerching!

Next Ubuntu LTS in 2010, unless Linuxes synchronize

Nick

efficient debugging

The point is not to make all the distros look and feel the same, it's more about commonality of effort.

If the releases are synchronized then you can be fairly sure that when you're bug fixing before a release then the external developer you want to talk to won't be on holiday, at a conference, busy with other stuff etc.

They will also be up to speed and working on the same version that you are and it won't take them a day to build a new test system to replicate your problem.

It will also be much easier to organize other co-ordinated development efforts like "Bug Days"

ISP typo pimping exposes users to fraudulent web pages

Nick

302 or 303

Isn't a 302 (Moved Temporarily) or 303 (See Other) status code the least bad way to implement this (although how many browsers implement 303 I don't know).

It could then redirect to a page which is clearly under the ISP's control.

Personally I think it should be up to the browser to deal with it rather than the ISP but I guess they don't want to pass up a revenue stream.

You're not forced to install the latest version when it's released. Minor releases are supported for 18 months. The long term support (LTS) release is supported for five years (and the patch frequenciy will be lower if you're not on the latest release).

RM to push new HP sub-laptop to schools

Re: £300 is not a cheap laptop

Flocke Kroes wrote:

"XO has a screen you can read in sunlight, stands a reasonable chance of surviving being dropped, does not make you a target for muggers and is far cheaper."

The XO is also one of the slowest machines to boot up and launch applications that I've used in a long time.

Add in the fact that the Sugar interface will not be easily integrated with the rest of the school's IT framework (different applications, no email client, default web browser doesn't cope well with media rich sites, different ideas about file systems, etc) and it's not really a sensible solution.

opening port 22 in a firewall for sftp leaves them vulnerable to bypassing the firewall using ssh port forwarding.

"I, for one, suck in any e-mail addressed to nonexistent addresses on my domain, no bounces here, no sir. Though it doesn't get read, it just gets piped to /bin/true. You wouldn't believe the number of imaginary addresses spammers try, either."

Are they spam to imaginary addresses at your domain or are they bounces which used imaginary addresses from your domain in the From: field. I had lots of trouble with the latter because:

A spambot opened an smtp connection to my domain, sent a "RCPT TO:" for a random address, got a "250 OK" back and then broke the connection.

It then knew that all addresses at the domain are valid and wouldn't raise any flags with anti-spam.

Spambot then sent out thousands of spam emails using fake names at my domain, most of which bounced and ended up in my inbox.

If you're eating all your mis-directed mail then spammers may use your domain name to send spam. I doubt it will cause you any problems but I was worried about ending up on spam blacklists.

Microsoft dropped Vista hardware spec to raise Intel profits

Nick

Life-cycles

Old Skool planning for the life-cycle of software used to be that:

1. On release it runs on high-spec hardware

2. Within less than a year most mid-range hardware will run it.

3. By end of life-cycle it will run on virtually everything out there.

If they designed for the machines that were around at the time then they might have to leave out some of the gee-whiz stuff that everyone loves so much ;)

The hardware people are happy because it drives sales, the software people are happy because they don't have to bother too much about efficiency.

This is all very well as long as the hardware is rapidly getting better but this is no longer really the case. The lastest machines are not light years ahead of kit which is a couple of years old.

The jump from desktops to laptops has probably lead to a decrease in average graphics capabilities.

Also for the first time there are low spec machines which are starting to give a half-decent user experience and the latest version of Windows won't run on them.

It takes a while for a lumbering giant to change direction. I'm guessing that they're working on something, perhaps even a cut-down version for the next release. When that arrives I might even prefer to run on it on my more powerful hardware.

Apologies for the slight tangent.

Network Solutions sued for price fixing

Nick

Re: Unanswered question

Chris C wrote:

"The only way this could possibly be necessary to "protect" their customers is if third parties were actively registering domains queried through Network Solutions' servers. And the only way third parties could get those queries is if there was a pretty big security hole in Network Solutions' servers."

It's just a http request so any network admin between your machine and their server can see it in the clear.

I haven't seen proof that Network Solutions sells the search data to third parties, but they would be within their rights to do so (and it's probably worth quite a bit of money).

And it's not just Network Solutions who can monetize DNS queries. Any big ISP running a nameserver could keep count of common mis-typed domain names which don't have a record and sell that information to squatters.

You can use command line tool like "host -a domainname.com" (or digg, nslookup, etc) to see if a domain is registered and this won't trigger the front-running. If it is registered then you can then go to the whois and take a closer look at who it's registered to and when it expires.

@Nick: No, they don't have to pay a fee for these registrations.

Elonex punts £99 Linux laptop

Re: Re: Here's more details...

I agree with John about the specs. I have an OLPC XO-1 which has (for what it's worth) a 433MHz processor and 256MB of memory. The lag starting applications is very noticeable (~10 sec), as is page load on graphics heavy websites. I think that the level of the Eee is about as low as you want to go with regards to specs.

Star Trek XI release knocked back to 2009

Nick

Reimagined, not prequel

I blame Ronald D Moore for this.

Since he "reimagined" Battlestar Gallactica they've been trawling the archives for things to resurrect: Bionic Woman, Flash Gordon, Sarah Connor Chronicles, etc

Initially I had my doubts about the new BSG but was won over because it was well made and had an edge and grittiness that the original didn't have.

Watching the teaser I can see some similar "less polished" look.

However I think less fans of the original aren't going to excuse any major rewriting of the canon, but the producers are probably aiming to try and bring new younger fans in the right demographic who haven't seen the original.

SCO details bleak future

Nick

It can't abandon it's court case with Novell.

Having read some of Groklaw then as far as I can tell it can't abandon it's court case with Novell.

The judge has ruled that SCO collected revenue on behalf of Novell and took a cut.

SCO hasn't released all of this money to Novell yet and the pending court case is solely to determine the actual amount of money involved.

Legally it's actually Novell's money which is being held by SCO rather than being money SCO owes to Novell. This is an important distinction because it puts Novell at the top of the list to get their money, in front of the taxman, lawyers, other debtors etc.

They filed for bankruptcy just before the court ruled how much of Novell's money SCO has and got the hearing delayed. It can't go into liquidation before that hearing is concluded (starts at the end of April) and SCO gives Novell it's money back.

... apart from the fact that ISPs can't proxy content on SSL websites.

So, either you host your images on a non-SSL server which will pop-up browser warnings about mixed secure/non-secure content or you serve them on an SSL server within your domain.

For sites like Gmail where most of the content is personal then this may not be a major issue but for an e-shop like Amazon then this would be a big factor. Given the number of "304 Not Modified" messages I see in my access logs this would increase their bandwidth costs by orders of magnitude.

"So why don't they enforce SSL? What's the overhead to them? I suppose it takes a little CPU to run the encryption algorithm but surly not that much."

HTTP is stateless therefore once it's served a page it's done. Each webpage is a separate transaction.

SSL is a session, so it has to keep the connection alive until either it's closed or times out. Too many concurrent users with a long timeout and you could run into problems.

You can't proxy images on SSL sites.
