+ - Questionable Patents From MakerBot-> 1

Submitted by Anonymous Coward
An anonymous reader writes "OpenBeam USA is a Kickstarted company that builds open source aluminum construction systems (think erector sets). One of the main uses for the system is building 3D printers, and creator Terence Tam is heavily involved in the 3D-printing community. He's now put up a blog post about some disturbing patents filed by MakerBot. In particular, he notes a patent for auto-levelling on a 3D printer. Not only is this an important upcoming technology for 3D printers, the restriction of which would be a huge blow to progress, it seems the patent was filed just a few short weeks after Steve Graber posted a video demonstrating such auto-levelling. There had also been a Kickstarter campaign for similar tech a few months earlier. Tam gives this warning: 'Considering the Stratasys — Afinia lawsuit, and the fact that Makerbot is now a subsidiary of Stratasys, it's not a stretch to imagine Makerbot coming after other open source 3D manufacturers that threaten their sales. After all, nobody acquires a patent warchest just to invite their competitors to sit around the campfire to sing Kumbaya. It is therefore vitally important that community developed improvements do not fall under Makerbot's (or any other company's) patent portfolio to be used at a later date to clobber the little guys.'"

Comment: Combined it with the network of lockers (Score 1) 243

If this was combined with amazons network of lockers, they could pre-ship items they anticipate to sell into some of the lockers in that area, then when someone orders an item you can offer them immediate delivery if they are willing to go collect it from a nearby locker.

You would need some pretty accurate algorithms to make this work, as the space available in any given set of lockers is very small, but you dont have to be quite as accurate as per-customer, just down to the set of customers in the vicinity of the locker, and/or have used that locker in the past.

I worked for NTL briefly over a decade ago, just when they were first trialling cable modems, there was talk then of the possibility of offering Ethernet to the Premises, but it it didnt and couldnt happen because of the infrastructure costs.

Those little cabinets at the end of each street, where the fibre optic network terminates, were made to fit exactly all the equipment needed at the time, there is no expansion room at all to add ethernet switches, or fibre switches, or well anything.

So they would have to rip out and replace all the cabinets on every street across the country in order to offer any terribly new or exciting services to the masses, something i dont see them doing anytime soon, if ever.

all video codecs decode to YUV data, as a result pretty much every GPU for over a decade has included hardware acceleration for handling that.

any sane person wanting to modify or overlay on that data would do so in YUV space, but not adobe, flash goes and hauls the entire frame over into RGB space, a big cpu hit in itself, then does its overlays, then expects the video hardware to help it with this rgb mode video it has, fail.

i dont care how much legacy code there is in flash expecting rgb mode, converting all you drawing operations to yuv (on the fly if necessary) and thus keeping the video data in yuv has got to be way way faster.

not doing this right is just plain laziness on adobes part, as has been pointed out.

Question 1:

Your phone can do "multitasking" -- explain to me what the advantage to this is? I mean, the advantage over the iPhone, that is - since the iPhone is obviously multitasking as it will play music, check your email, run a phone conversation, and allow you to launch any 3rd-party app, all at the same time. I suppose my question is, what real-world advantages have you seen with this "multitasking"

Heres a really simple example for you: MyTracks, a pretty easy to use GPS track log program you can get free off the market, i can run it, start it logging, and then do something else whilst it continues to run in the background.

Its not an application that needs my interaction other than to start and stop it, and i dont want to lock my entire device up doing that simple task all on its own.

I think its almost on the right lines, but the tux part is too much.

What you want is one of those trendy lifestyle type adverts, show a young trendy person going about their daily trendy lifestyle, interacting with various things along the way, phone, laptop, ATM, etc etc. Then go back and point out that every single thing they used was running Linux.

There are a number of successful brand advertisments like this already, that in essence are telling you "you too can have a cool life like this, and product/company $foo is what makes it happen"

Software

+ - Linux archive file format with redundancy record? 2

Submitted by xtracto
xtracto (837672) writes "Is there an Open Source program or file available under Linux which can duplicate the feature available in the RAR file of adding a "redundancy record" to the file in order to allow recovery of the file if corrupted? I need to backup a vast amount of text data (log information for a scientific experiment) and currently I am doing it by compressing the data using tar and bzip2 format and then archive it to DVDs, but I would like to add some redundancy to the files (maybe a standalone program on top of the tar-bziped files). Is there anything like that on Linux?. Note that RAR is not a choice because of the closed file format (as this is scientific data which might be available for everyone in the future)."

Dispirited (316703) writes "Not very long after being bought off by Citrix and incidentally announcing their "commitment to the Windows platform", XenSource releases a new version of their administration console that drops support for Linux. The formerly multi-platform, Java-based administration tool is now Windows-only. The rioting in their forums has already begun. Why drop support for Linux when the previous version worked wonderfully there?"
Amiga

+ - Amiga in an FPGA released under GPL-> 2

Submitted by exolon42
exolon42 (1140715) writes "This is a mandatory read for every (former or current) Amiga hacker. You have to give it to the Dutch: tulips, cheese, and now a guy named Dennis has recreated the original Amiga chipset in a Xilinx Spartan-3 FPGA, and recently released all sources under the GPL to boot! This includes the design of a PCB containing the FPGA, the required MC68000 and normal PC-style hardware connectors so you can build your own. A thought-provoking fact is that the Verilog-sources for the recreated chips (Denise, Paula, Agnus etc.) are only around 500-1000 lines each... chips in the eighties didn't contain 1 billion transistors!"
