Re: Time for The Register to weigh in methinks.

A damn good idea. And perhaps a popular public figure with a very large twitter following and an interest in history, gay rights and technology could be recruited to raise awareness of this campaign amongst the general population?

Oh wait, Mr Orlowski has other ideas. http://www.theregister.co.uk/2014/01/28/stephen_fry_says_kildall_was_cracked/

Behold the world's first full-colour 3D printer

Re: HP?

HP dipped their toes in the pool, then pulled them out:

In January 2010, Stratasys signed an agreement with HP to manufacture HP-branded 3D printers. In August 2012, the HP manufacturing and distribution agreement was discontinued.

I don't know if HP are still pursuing 3D printing in any way.

Re: to widen the discussion...

I agree with Don's gist.

On points of detail though, my take is that technology like 3D scanning and image recognition will allow 3D printers to compensate for user ineptness. E.g the printer will be able to 'see' that what it is laying down on the bed isn't what is desired, and so will adjust the parameters accordingly.

>anyone not wearing one when riding a bike is an absolute idiot of the highest degree.

The statistical evidence in favour of bicycle helmets is not as clear cut as one would assume, though it does appear that, on balance, wearing a helmet is a good idea.

I would recommend the film 'The Crash Reel' to anyone. For a film about the consequences of Traumatic Brain Injuries, it is surprisingly uplifting. That film, and also the movie 'Senna' were on my mind when I heard the news about Michael Schumacher's crash last month.

>Me thinks this needs to be opensourced back into the community, after all their business wouldn't be anywhere without the opensource reprap.

Where did you get that idea, rmwebs?

Stratasys have been selling commercial 3D printers to paying customers since the early 1990s. The open-source RepRap project, based on Stratasys's Fused Deposition Modelling (as opposed to alternative rapid-prototyping techniques such as Laminate Object Modelling, Selective Laser Sintering or Stereolithography) has been running since 2004.

Disclosure: Stratasys sent me a sample, a 4" long 3D-printed adjustable spanner in 2001, made of a nylon-like plastic. Only yesterday did I manage to print (mostly successfully) a 3D object on my own RepRap Ormerod printer (the one being sold by RS Components). The trick of coating the bed with a 50:50 water/PVA mix and allowed to dry seems to have solved my warping problems. It's been (mostly) fun to assemble, but don't believe the "Kit takes two hours to assemble" claim on the RS website! For a honest and broad overview, you can of course check the Reprap Forums > Machine Variations > Ormerod: http://forums.reprap.org/list.php?340

Re: A 3D printed cycle helmet?

In industrial design, people understand the difference between an appearance model and a functional prototype.

That said, bicycle helmets are usually made of composite materials (i.e, a composite of polystyrene and a gas such as carbon dioxide) so that the gas can compress on impact. In theory, additive manufacturing can be used to create a structure with pockets of air which can meet or exceed the relevant safety tests. However, I can't think of a reason as to why you choose this process over traditional means, other than the promise of a helmet that is 'tailored' to an individuals head shape by means of 3D scanning.

I don't want my bike helmet to be as strong as possible. I want it to deform on impact in order to reduce the acceleration exerted on my brain. That is why they are made of polystyrene or, more recently, cardboard:

Re: The Bitmap Brothers

>Although I can't actually remember the game being all that good...

Gods looked great, but it was a bit ploddy, flip switches to open doors, and relying on every health and weapon upgrade you could get.

Platform games were a bit scarce on the PC at the time, with Sonic and Mario of course being exclusive to Sega and Nintendo. Heck, even the 8-bit Master System seemed to have better platform games, such as Wonderboy III.

Flight simulators and strategy games aside, the PC felt to me like the poor man of the gaming world until the rise of the First Person Shooter.

Re: New product category

> Next step is probably the additional capability to drop the mobile device into a dock and it becomes your desktop PC

There are two main reasons to want to do that: 1, access to files that are only on your mobole device, and 2, saving money by not duplicating processing hardware.

There are probably better (and more redundant) ways of synchronising files, and the cost of hardware required to do a good many tasks is very cheap these days.

Altcoins will DESTROY the IT industry and spawn an infosec NIGHTMARE

Dave 126
Silver badge

In cryptography, scrypt is a password-based key derivation function created by Colin Percival, originally for the Tarsnap online backup service. The algorithm was specifically designed to make it costly to perform large-scale custom hardware attacks by requiring large amounts of memory. In 2012, the scrypt algorithm was published by IETF as an Internet Draft, intended to become an informational RFC, which has since expired. A simplified version of scrypt is used as a proof-of-work scheme by a number of cryptocurrencies, such as Litecoin and Dogecoin.

My old man is in the market for a new phone, his previous small-screened Android phone having irritated him - especially the keyboard and the battery life. A fair few of his friends have iPhones, and they have a reputation as being easy to use, yet my father's chief complaints with his current phone is that the keyboard is too small. I was just about to suggest he get a Google Nexus 5 (good value, big screen, good battery life, virtual keyboard can be swapped out for another one).

However, on Saturday his friend showed us her Nokia 1020, specifically the messaging app in which she had bumped up the font size. Clean, legible, large... it looked very good (Actually, it looked like Rockbox on my old iRiver H320).

So, beyond the lack of apps compared to Android and iOS (which doesn't bother my old man a bit), is there any reason I shouldn't recommend he get one?

I don't use Adblock on The Reg, because a, I like The Reg and b, their adverts are not normally intrusive - they get the balance correct. A month or so back there was an annoying Microsoft advert here with audio, but I can only assume that this was a rare oversight. Were that kind of advert the norm here, then yes I would enable Adblock.

Mystery 'doughnut' materializes in front of Mars rover: 'OH MY GOD! It wasn't there before!'

Dave 126
Silver badge

One of the wheels is not working properly:

Opportunity’s front right steering actuator has stopped working, so [NASA Mars Exploration Rover lead scientist Steve Squyres] identified that as the possible culprit behind the whole mystery.

Each wheel on the rover has its own actuator. Should an actuator jam or otherwise fail, the robot’s mobility can suffer. In the case of this wheel, it can no longer turn left or right. “So if you do a turn in place on bedrock,” continued Squyres, “as you turn that wheel across the rock, it’s gonna kinda ‘chatter.’” This jittery motion across the bedrock may have propelled the rock out of place, “tiddlywinking” the object from its location and flipping it a few feet away from the rover.

4. Cameras calibrated for lens distortions, multiple shots processed by some pricey software - manual finessing required.

5.
