Perhaps not surprisingly I've got one, and a CNC controlled mini-mill, and some casting supplies. The need that motivated that purchase was doing robotics. Small robots suffer a bit from credible build materials. On the one hand you can make them out of "traditional" DIY materials like wood but working the material and making reasonably light weight robots is hard. Heavy robots need stronger motors and bigger batteries etc etc. Converting toys into robots works but you are constrained by what ever the manufacturer did, and since they are being as cheap as possible you often find that the thing they could have done but didn't would have really helped (like having three attachment points all about the same level). Custom mechanics are pretty much out, except what ever you can do with Meccano or Lego Technic or Erector stuff.

Thus mechanical fabrication is a problem, and automated fabrication is better than manual fabrication, both from a fit and finish perspective and a design perspective.

That said, I've met people with 3D printers who printed like half a dozen things on them and then stopped. They couldn't think of new things to print. They were excited about the concept but it hasn't worked out or the finish wasn't actually as good as they had imagined it would be.

If you are a robotics enthusiast I think its a great tier 2 tool, like an Oscilloscope.
> In a similar vein, this is why Piriform cut them off from providing CCleaner via Ninite. Because automatic updating is a feature of CCleaner's business model, too. The paid version of CCleaner has automatic updates.

Maybe CCleaner should rethink that one, that is an awful business model. I wonder if they do the same thing with their OS X version too, because if so they might want to have a chat with the MacUpdate Desktop folks too.

IMO you can't blame app update tools for breaking a business model. That's a really idiotic business model to begin with. Charging for updates, fine. But charging for the ability to auto-check for updates? There is a reason nobody else in the industry does that. Because it's stupid.

ah yes i agree $9 is not low, but i think we need to communicate more of what you'll receive in by mail.

all in all, this a lean startup test of the idea. i'm not married to the price point, and thanks for the feedback!
Same here. For something that I wouldn't use all the time like a 2D printer, OfficeMax or a hacker space makes a lot more sense. And since they're still comparatively complicated and failure prone, that lets me just pay a bit more and not have to worry about all of the maintenance.

Which one ? I'm interested :) . There's very little available information on the creation process of a Tetris game (well, publicly at least).

20G gameplay (i.e. where the piece spawns on the floow)) is definitely an issue, but I think that using (or rather: abusing) the Tetris Guideline very lax rotation system and "climbing" potential[1] you may be able to reach a sufficient mobility of your piece so you can place them wherever you want.

Government transparency is a distinct issue. What I was speaking to is the low barrier to opening a blog under a pseudonym, posting something and sharing it without any long-term disincentive to be accurate or truthful.
Wikileaks is not the end-all, it is a stepping stone. Extremely damaging or valuable secrets or only known to a very limited group, so anonymous information isn't really anonymous in that sense. Wikileaks is just another gatekeeper, it isn't a distribution network. Assange and his brand have an audience, but that's all it is when you break it down critically.

It would have minimal effect on data usage, as you only ever need to report back when you've found something, and you only need send a 32-byte precomputed seed every ~10 minutes or so.

It would, however, absolutely demolish the battery. This kind of computation is pretty much directly proportional to power use, and modern smartphones are power-limited. So, if you mine at full tilt, the smartphone will drain the battery literally as fast as it can, and get really hot doing so. You can limit the hashing speed, but this will only spread the work over time. It won't change the fact that to get any good hashrate out of the system, you basically have to consume all the battery.

However, all of this is pointless because you'd need millions, possibly tens of millions of concurrent users to match a single modern $1000 mining rig. Computing sha hashes is a workload that fits special-purpose hardware really well. GP hardware simply cannot properly compete anyway. And now as ASICs are driving up the difficulty, you'd be making much less than 1$ of profit for 1$ of electricity consumed.
No, he's just messing with you. It's mostly SML.
I'd be surprised if it were worth it. Even with fairly efficient GPU mining rigs it's getting close.

That CPU won't be appreciably more power efficient than a standard i7-3770. It just constrains its clock speeds in order to stay within a lower power ceiling.

TDP is all about cooling capacity and PSU capabilities. If you're worried about saving energy, get the processor that will run at the highest speed while computing so that it can get back into power-saving mode sooner. And you can always under-clock the standard desktop CPUs if you really want to - a 3770 can be configured to behave pretty much like a 3770T by tweaking the base and Turbo multipliers.

"Yet that societies are not artificially put together, is a truth so manifest, that it seems wonderful men should ever have overlooked it. Perhaps nothing more clearly shows the small value of historical studies, as they have been commonly pursued. You need but to look at the changes going on around, or observe social organization in its leading traits, to see that these are neither supernatural, nor are determined by the wills of individual men, as by implication the older historians teach; but are consequent on general natural causes."

And if the rate was 15% your guess is there would be even more start-ups or less? And if more, wouldn't that be more valuable for the Israeli economy than to give this 30% difference to politicians to waste?

>And yes, it's about policies that make sense for the >economic constraints of the government and the values of the >voters. Key words there being values of the voters.

Agree 100% here with you. However when people vote for something they rarely see the side-effects that quite often are much worse than the potential benefits. Like with cough medicine that gives you heart attack. People don't see things through at times. They'll vote for a politician who promises the most, understanding he'll go deeply in debt and not really caring that their children will have to pay it all off. Democracy gives the people great power, the problem is they don't want to accept responsibility for it.
I have a great example here: In 1990s Democrats in the USA got this really good idea that all Americans should have a house. Even ones who couldn't afford it. What they did is they told the banks: look we (the Government) are going to guarantee all the mortgages. If you give a mortgage to someone and that person stops repaying it, the Government will buy the mortgage back using taxpayers money. And you know people voted for it. So all the folks who really weren't qualified got mortgages they couldn't afford. How markets work is that there is a balance between greed and fear. You're greedy to give someone a mortgage but afraid he will not repay. The Government took the fear part out of equation. Obviously the whole thing had to collapse. And in 2008 it did. And what caused that? Good intentions, socialism - let's give house to everyone. Now everyone's screwed over. And the funniest part is that now they blame bankers and capitalism for that. It was socialistic idea from the start.

>France might have a very state-driven economy, but most of >the world's top economies certainly don't take the American >neoliberal wannabe-anarcho-capitalist approach.

US is much more socialist they you could think. They talk the talk but don't walk the walk. Currently in the US there are more people who get Government benefits than those who pay the income tax. That's not capitalism. If you want to see capitalism look at China.

Chinese Way of Doing Business: In Cash We Trust

I've built the RepRapPro Mendel from a kit about 2 months ago. Don't have any "real" use for it - it's just a cool toy to have, considering it doesn't cost that much (paid 640 EUR for the kit). But it may come very useful if I try to build some hobby RC plane or quadcopter though.

Anyway, it's been working nice so far, though I did spend many hours tuning the machine and getting to know the various software (CAD, slicers, printer control). I'm currently in the process of installing another extruder, the primary reason being the ability to print water-soluble support material (PVA) - this makes it possible to print essentially any form, with no limitation on overhang angle.

I think the thing that needs most work in the open source 3D printer works is the development of slicing software and printer firmware. In particular, there is little consideration to how the layers interact with each physically. Currently slicers mostly work in a simple and predictable manner - but with more "intelligent" algorithms modelling the physical processes of a printer the print quality and/or speed could be improved without modifying the printer itself (except perhaps getting faster microcontrollers).

P.S. I'll be very careful buying cheap Chinese filament next time. It tends to have oil inside which makes it almost impossible to stick to any kind of surface, and requires bed cleaning after every print.
