Luckily the demoscene graphics showcase platform https://www.dwitter.net still enforces the 140 character limit! Keepon making those webgl canvas graphics!


And let's not forget http://tinytocs.org, a CS journal whose article bodies must fit into 140 characters.


Project co-author here. Check out our demo submission to Revision made with nin, "What Are You Syncing About", here: http://arkt.is/what-are-you-syncing-about/

View in chrome with webgl on for the best experience, or on your iPhone if you have a newer one!


Shameless astroturfing: I love zombocam; the only limit is myself!


My democrew (Ninjadev) has used this technique for multiple WebGL/Javascript productions over the last few years now.

You can see the final packed .PNG results here: Crankwork Steamfist https://stianj.com/crankwork-steamfist/, Everything is Fashion https://stianj.com/fashion/, and Inakuwa Oasis http://arkt.is/inakuwa-oasis/.

The tool used for creating both the demos and the packed .PNG is made by us and available on GitHub here https://github.com/ninjadev/nin/.


Also a Ninjadever. Daeken's blog post was one of the inspirations that led us to implementing this in our toolchain. p01's Matraka [1] was another. The PNG trick is pretty common in the js scene nowadays, with packing tools such as JsExe [2] readily available.

Oh man, I didn't know you guys released your tools. I'm a big fan of your stuff -- awesome to see such polished prods on the web. Happy to have helped enable some amazing work!


That first link froze my (rather old) computer - had to reboot!


The setup seems rather similar to https://github.com/arut/nginx-rtmp-module which I've used in the past. Perhaps they've bundled it with Nginx Plus without crediting the original authors? The project has a bit too permissive license for my taste.


Roman Arutyunyan is (or was previously) an engineer at nginx when he developed nginx-rtmp.

I work at Nginx, although not on the core development team, and to the best of my knowledge Roman Arutyunyan is still an engineer with us.


> Both NGINX and NGINX Plus support the features we’re discussing


But the nginx-rtmp-module does not support DASH with ABR to the best of my knowledge. Seems to be still an open issue https://github.com/arut/nginx-rtmp-module/issues/480


Me and a group of friends at NTNU spent the last three months implementing self-designed and working GPU from scratch in VHDL on a Xilinx Spartan 6 FPGA. At the same time as this, we also implemented fully working multi-cycle and pipelined MIPS CPUs for the same FPGA.

All of us came from software backgrounds, never having touched any hardware description language.

To get started I'd recommend reading Computer organization and design by Patterson and Hennessy (http://www.amazon.com/Computer-Organization-Design-Fifth-Edi...).

For the VHDL part, all we had available was this small basic VHDL compendium (not sure if I can redistribute it), open source github repositories from friends and classmates, as well as the always helpful vhdlguru.blogspot.com

So i'll reccomend following one of the open lecture series posted above :)


Would you mind making this effort open-source for a possibility to build completely open-source computer? The Novena laptop had all things except GPU because there is no open source GPU which would have all the schematics available. Some guy from Germany, I think, is also working on open-source design GPU on FPGA.


Hello HN! We, a group of summer interns at Nordic Semiconductor, have made an Internet of Things-enabling platform based on ARM's mbed technology. We make it easy to rapidly prototype and develop Bluetooth LE enabled devices - get up and running in under 10 lines of code, written directly in the browser.

We hope to create a community around BLE devices where developers share their ideas designs with each other. Everything is open-source, of course, with lots of supporting materials, together with companion apps for both Android and iOS.


I have spent 10 minutes trying to find an actual working "buy now" or "add to cart" button, but sadly, those are no where to find.

I followed the link from Location Puck Tutorial Page[1] to mbed.org page[2] which does have a "Buy Now" button, but clicking on it took me back to the vendor page where it was completely unclear how am i supposed to buy this!

I understand you have this amazing bluetooth board, that I can do wonderful magic with it. But how do I get one? Give me a straight direct link to buy this thing.

How can you possibly think that this can be called "The Raspberry Pi of Bluetooth" when even buying this looks like an impossible mission.

As I said it looks pretty cool and I congratulate you for taking it so far. I think there is a lot of work to be done to enable hobbyists/hackers to buy this device easily without jumping through numerous corporate hops.

Also if I understand it correctly, I need a special IDE to be able to hack on this device? If that is really the case, I think there should be some work to decouple the device from the IDE to increase the openness and remove any kind of vendor lock-in.

But then again, i might be completely off and this device is not what i thought it was. Good luck anyway!

I was curious as well, here's a shop I found with what appear to be the products from the tutorials..

http://www.semiconductorstore.com/Nordic-Semiconductor/


Wow, thanks! That's what I was looking for. Why the article didn't link to the exact product page on this store is really beyond me.

Edit: They added a direct link to the store. Great!


Thanks for the feedback (I'm one of the summer interns that worked on this). We've added "buy now" links that go to http://www.semiconductorstore.com/cart/pc/viewPrd.asp?idprod... .

The IDE is a webapp (!), no downloads required to get hacking. That being said, it is possible to use other tool chains, such as gcc or µVision, but we haven't focused on that in the tutorials.


Great, thanks for adding the direct link to store page.


Cool idea. I would recommend making it clearer how to order the kit though. I read your page with interest, then reached the bottom without really knowing what to do next (yes, I did see that "tutorial" link).

I understand that as interns you may not have control over the purchase process, but a "Buy now ($XX)" button at the bottom would be a step in the right direction.

(for the curious, it appears that an nRF51822 evaluation kit costs about $/€ 80).
