You mean, not much profit margin?  The guy touting this is the founder and CEO of the company (Adapteva) who designed the co-processor.  He says the biggest hurdle is the initial mask for fabricating the chips.  After that, it's all silicon and overhead, and since the penny-sized coprocessor chip uses 1/10 the silicon of a standard CPU, it's naturally going to be less expensive to manufacture.  Also, consider the Raspberry PI and Arduino at less than $50 per unit, and those projects are doing rather well.  If Mr. Olofsson's idea works out like he plans, I think he'll do OK.

From the specs and interviews with the designer, it's a 64-core Epiphany co-processor sitting next to a dual-core ARM CPU, so I wonder how much is managed by the system, and how much is bare metal. It's got expected virtual speeds up to 50GHz.  I know, in modern computing terms, Gigahertz is a trivial benchmark, but for a chip that consumes less than 2 watts, it's impressive.  
Apparently though, the object isn't exactly speed, but functionality; an inexpensive platform for learning how to program for parallel computing, almost like a hardware emulator of more serious iron, to make it easier for students to get into parallel and multi-threading concepts now, just when it's starting to grow.

From an interview in Linux User & Developer magazine:
LUD: One of your target markets for the Parallella is education, much like the Raspberry Pi. How important is it that universities teach the next generation of programmers to harness the parallel processing capabilities found in modern hardware?

AO: I think it’s a huge challenge and problem right now. I mean, everybody knows that the future’s parallel. What GPUs are showing, and what we are showing, is that parallel’s not even the future – it’s now. There are massively parallel systems right now that could give a huge boost to applications, but there’s nobody who has the energy and the know-how to rewrite a lot of applications for that.

In the future, it’s just going to get worse. Single-threaded processors are saturating, and I think there is agreement on that, so you need to go to heterogeneous computing, and to do that you need to educate from scratch all the new programmers who come out. The curriculum needs to change immediately, because we’re losing time.

All the people out there who are experts at single-threaded programming and who maybe haven’t taken the plunge to parallel programming, they need to be educated and retrained and gotten up to speed. It’s a big context switch for the mind, to go from serial to parallel programming, and really the only way to get fundamentally higher speed-ups is to rewrite your program code from scratch. There’s really no magic bullet.

They've reached their Kickstarter goal, so I hope the goods appear soon, this looks simply delicious.

Parallella: A SuperComputer for Everyone
Inspired by great hardware communities like Raspberry Pi and Arduino, we see a critical need for a truly open, high-performance computing platform that will close the knowledge gap in parallel programing. The goal of the Parallella project is to democratize access to parallel computing.

Good one, Tim!  Grin Grin Grin  Thmbsup

I started one about the toils of using Linux, sung to the tune of "Fire and Rain" by James Taylor.
It started with the chorus:

Oh, I've seen trial and I've seen pain
I've seen Gentoo installs that I thought would never end
I've seen X drivers fail and TTY was my only friend
But at least I'll never see a Blue Screen again...

There should be more, but that's as far as I got.  Maybe I should work on that.  huh

Yeah, I still do not understand AT ALL why environmentalists would encourage moving away from a standard tungsten filament bulb that has only 5 components (glass, steel, aluminum, tungsten, lead), only one of which is majorly toxic (lead, in the solder), and towards CFL bulbs which contain not only lead (solder for the components on the circuit board inside), but mercury(!) and whatever the handful of components driving the thing are composed of, not to mention the environmental impact of manufacturing all those components, shipping, and assembling, when a filament bulb manufacturer can fabricate most of it's components right in the same factory.

Thanks for the references, I'll be looking those up later.  Thmbsup

Thanks guys, but...
1 - This is about learning the HARD way
2 -
Windows 98, ME, NT4, 2000, XP, Vista, 7, and 8
.NET/Mono, Project is a user interface (UI) system
My goal is to make Expresso the best .NET regular expression development tool on the planet.

(note: Mono != .NET)

I'm a Linux-only shop, and I've been wanting to learn regular expressions the HARD way for a while now.  It'll help with text file manipulation and file searches.  C is on my radar, but as I can barely handle Pascal, it may be a while...
358  Other Software / Developer's Corner / Re: Learn C (and other things...) the Hard Way on: December 28, 2012, 04:14:28 PM
Wow, nice resource.  I'll be looking at this later; especially the Regex's; been wanting to learn that for a while, especially as it seems a pre-requisite for Linux hackery, and I never bothered to learn much beyond the basics.
Thanks to you and Josh  Thmbsup

Ooooh boy, do I hear you on that one.  Every year I get more Linux-savvy, the more I tend to umm... play.

I've got a kabillion packages installed that are probably obscure libraries for something I wanted to compile, but those are usually fairly minimal.  What's driving me nuts is my Applications menus getting longer and longer with stuff I KNOW I'm going to use again someday, so don't have the intestinal fortitude to actually wipe out.  Oh,and the custom icons and shortcuts. I made for many of them, with softlinks to God knows where just to make them run.  Same with my /opt directory, full of stuff I compiled and ran, then discarded but never did a 'make uninstall'.  THAT's scary ground to walk on.

I do keep a very organized home directory though; everything sits in ~/Downloads or ~/temp until I decide it's worth keeping or nuking.  If I can't decide, it probably needs a nuke. One of these days, Wheezy is going to land in Stable, and I'll have justification to backup/nuke/upgrade.  
The thing about wastelands is there's so much room for gardening...  Grin

The case is 3-D printed, so if it's missing a handle, one could easily be added.
Speaking of which, the current configuration could easily be made to look like a miniature Osborne "luggable".  Extra geek cred!!  Thmbsup

Well, after using Litestep with x-modules on Windows, e17 shouldn't be too much harder to wrestle with, though I do admit I have shied away from it in the past BECAUSE of option overload.  Xfce has done so right by me I haven't been pining for anything different, but maybe I'll give it a shot.

I've got a sourceforge account, I'll try to drop in there to lend a hand, though I may not be too up on game genres.

Many of those threads become legendary on their respective forums, often taking on a life of their own.
By way of example, there is the "Burst Box" thread on diystompboxes.com.  It goes off the front page for a while, then jumps back to the top as more people add to the insanity.  I kinda feel sorry for the kid who started it, and somehow it became a thread about the end of the world and Scarlett Johanssen.  Don't ask me how...
34 pages now, so this one has it beat, but there for a while...

The more I read about stuff like this, the more I'm convinced that the R-Pi, Arduino, Beagle Board, and now Bunnie Huang's open-source laptop may well be the savior of general-purpose computing.  Let Microsoft have their fnikcug Secure Boot.  As far as I know, Microsoft isn't going to planning on releasing Windows PI, are they?... 

Didn't think so.

BTW - Element14/Farnell now has the 512MB version and much better shipping times.
I'm ordering one as soon as I have the extra cash...

From time to time I like to test what sneaks through the OpenDNS filter; not for my own entertainment, mind you, I've got a teenage boy in the house, and I'm happily married... so sue me; just doing my job.  Anyways, not much does, and it's certainly smarter than ANY of the 'Parental Control' filters out there, with one exception... Google Image search.  So this news is actually of the good variety.
However, I just noticed something else strange going on; putting choice search terms into the image and video searches for Bing and Yahoo with SafeSearch off brings up nothing but a page full of 'broken image' links.
[attach=1]  huh
Not undesirable, but strange nonetheless...
373  Main Area and Open Discussion / Living Room / The REAL reason Valve is developing Steam for Linux? on: December 12, 2012, 03:19:46 AM
Total conjecture, but it's been whispered around for a while now...

Connect the dots: Valve’s Big Picture could be a Linux game console
When a game developer can offer their games directly through the Windows Store or Mac App Store that’s built into every new computer, why go with Steam?
Perhaps that’s one of the reasons that Valve co-founder Gabe Newell is calling Windows 8 a "catastrophe." Perhaps that’s why Valve is building Steam for Linux.

Valve Prepping Custom PC Hardware To Compete With Next-Gen Game Consoles
It’s likely that Valve will assume the role of a boutique PC manufacturer, taking standardized hardware and customizing it (as well as software) for a living room experience. This would entail pre-installing Steam, but I wouldn’t be surprised if, with Valve’s recent love affair with Linux, the company wasn’t neck-deep in developing a custom Linux distribution.

from my friend who hates Linux, but likes to game, and may be changing his mind...
