I see a couple companies here throwing around the term "high performance", and as someone who has worked with actual high performance computing (HPC) technology, the perversion of this term is annoying.<p>What is HPC? HPC is writing software for supercomputers. HPC is implementing parallel algorithms. HPC is Intel's lab on a chip, a Linux cluster with Infiniband networking, etc.<p>&#62; SpinPunch makes high performance browser games to rival PC and console titles.<p>No, SpinPunch, my browser is not a Linux cluster with 1024 nodes, each with 8 CPUs. JavaScript is not HPC. C, C++, and Fortran are high performance. MPI and the Intel Math Kernel Library are high performance. Using MPI-IO to interact with a parallel virtual file system to read a 1 GB file efficiently is high performance.<p>&#62; SpaceBase is a server-side, in-memory, high-performance, concurrent and distributed spatial data-store...SpaceBase is implemented in Java, and provides a Java and C++ APIs.<p>That sounds great, SpaceBase, but I didn't see any white papers or mentions of academic journal articles on your site. If your revolutionary system is high performance, you have to prove it. At the very least, you need a white paper to show how fantastic your HPC software is. Here are a few examples of that:<p>Google MapReduce: <a href="http://static.googleusercontent.com/external_content/untrusted_dlcp/research.google.com/en/us/archive/mapreduce-osdi04.pdf" rel="nofollow">http://static.googleusercontent.com/external_content/untrust...</a><p>Message Passing Interface (MPI): <a href="http://www.sciencedirect.com/science/article/pii/0167819196000245" rel="nofollow">http://www.sciencedirect.com/science/article/pii/01678191960...</a><p>Intel Math Kernel Library: <a href="http://software.intel.com/en-us/articles/intel-math-kernel-library-white-papers/" rel="nofollow">http://software.intel.com/en-us/articles/intel-math-kernel-l...</a> ScaLAPACK: <a href="http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=234898&#38;tag=1" rel="nofollow">http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=234898&...</a><p>Elemental: <a href="http://www.cs.utexas.edu/~flame/pubs/FLAWN44_revised.pdf" rel="nofollow">http://www.cs.utexas.edu/~flame/pubs/FLAWN44_revised.pdf</a><p>You're walking a very fine line when you claim that your system is high performance, and I am not impressed by the total lack of any paper describing how you came to this conclusion. I found this snippet from the company's blog:<p>&#62; It scales gracefully across CPUs and across a computing grid. It scales so well that it allows building large shardless MMO games. In-fact, shardless MMO games and virtual worlds were one of the use-cases SpaceBase was specifically built to handle. (Distributed SpaceBase, or SpaceBase-on-a-grid is currently in the advanced stages of testing, and will be available for evaluation and purchase within a couple of months. The single-node, multi- and many- core deployment is available for evaluation right now!)<p>Please, just show us the numbers!<p>tl;dr HPC is all about scaling across computing clusters. Show us an experiment with speedup numbers.

Is it just me or most of these startups don't have any "Wow factor"?<p>I mean 9GAG has been around for quite some time now and what does it bring to the table?<p>Mark.io is basically canvas / quickmeme but with a slicker "Startup look".<p>Scoutzie could be a side project on Shown HN. Sacha Greif is doing something similar with Folyo.<p>CocoPad, I don't have word for this. I don't understand why this idea got accepted in YC in the first place.<p>Its not all bad though.<p>Bufferbox, instacart, Flightfox and some other are really trying to change their own industry / market and looks like true YC Startup.<p>Anyway, this is just a rant from someone who use to get excited seeing all the great startup from YC demo day.

Looks like a fine lineup with lots of startups useful for businesses.<p>Profig: when is this coming to Europe!<p>I find Easel very interesting as I've been looking for a hi-fi alternative to Balsamiq.<p>Coinbase sounds interesting but I have no idea what they are actually doing based on what it says on the web site. Also, I'm pretty skeptical when it comes to security and the BitCoin industry.<p>Submittable.com: two persistent feedback tools on the front page...? Anyways, the service sounds great for content heavy orgs.

You forgot 9GAG and Mth Sense, we should work on this together. Been running this list for a while: <a href="http://startupframework.tumblr.com/post/29465655158/yc-s12-companies-demo-day" rel="nofollow">http://startupframework.tumblr.com/post/29465655158/yc-s12-c...</a><p>And a list of YC S12 Rejects: <a href="http://startupframework.tumblr.com/post/29900354472/the-forgotten-yc-s12-applicants" rel="nofollow">http://startupframework.tumblr.com/post/29900354472/the-forg...</a><p>Hope this helps.

Somebody take a webshot of that page and send it to pg.<p>That's exactly what HN needs.<p>* <a href="http://i.imgur.com/xoMVr.jpg" rel="nofollow">http://i.imgur.com/xoMVr.jpg</a>

Betting on Instacart and Plivo to be the best out of this batch. Delight.io,viacycle,Bufferbox,virool,vayable and zapier come next.<p>The last supper picture has 15 disciples ;)

FundersClub gets the gold medal.<p>PG should ban social startups in the next batch just to rise the level a notch or two.

nice to see many "not pure software" startups, dealing with hairy physical brick-and-mortar issues

I wonder if 9GAG spoke to the Reddit founders at all during incubation /karmaconspiracy
