aconz2on The Nvidia DGX-1 Deep Learning Supercomputer in a Box

To be fair, they are comparing it to a dual-socket CPU; which is twice as fair as comparing to a single!!

What I was getting more at was: I want to know the relative performance compared to another 8 Tesla box. I know comparing apples isn't good marketing, but c'mon.

aconz2on The Nvidia DGX-1 Deep Learning Supercomputer in a Box

Check out the specs here: http://images.nvidia.com/content/technologies/deep-learning/...

though I'm most curious about what motherboard is in there to support NVLink and NVHS.

Good overview of Pascal here: https://devblogs.nvidia.com/parallelforall/inside-pascal/

1 question: will we see NVLink become an open standard for use in/with other coprocessors?

1 gripe: they give relative performance data as compared to a CPU -- of course its faster than a CPU

aconz2on An Introduction to Redex with Abstracting Abstract Machines

AAM was one of those things that made me say, "wow this is really cool" the first time I saw it. Luckily, I got to see this presented by Van Horn in class at UMD.

Link to the PDF of the associated paper http://www.cs.umd.edu/class/fall2014/cmsc631/papers/vanhorn-...

aconz2on Type safe OpenGL – Converting strings into types in D

This only seems useful for user-defined glsl types. The builtin glsl types would only have to be written out once as D types.

The general idea of "importing" types is a good one and I think this is what F# achieves with type providers. I've seen this applied to database schemas and filesystems, but never OpenGL.

aconz2on The Brick Wall of C++ Source Code Transformation

Are Nim's metaprogramming features fundamentally different than C++?

aconz2on The Brick Wall of C++ Source Code Transformation

I've been thinking a lot about source code transformations as a possible key for maintenance in the "future" of programming. Its interesting to see that the preprocessor, which is a source code transformation itself, makes other source code transformations much more difficult, if not intractable. I'm wondering if this inherent to any macro system since they are not bijective.

Two possible directions I see away from macros which would play nicely with source code transformations are un-macros and layers of languages.

Un-macros would take source and display it in the condensed form only for human reading -- this takes away from human writing power of course, which may have to get pushed into the editor. This could also allow for automated pattern discovery.

Layers of languages would look similar to Racket's #lang concept and current macro systems, but without the ability to escape back into the parent language. This creates a new language on top of -- not mixed into -- the parent language.

aconz2on TensorFlow: open-source library for machine intelligence

I was interested in whether the license only permits a single machine.

aconz2on IBM is trying to solve computing scaling issues with electronic ‘blood’

Very cool idea.

One thing I think is often overlooked in comparing brains with computers is that while they may be ahead on efficiency and density, computers win on many other metrics eg. They are easy to reprogram, they don't need sleep, etc.

And I'm curious how exactly brains are measured for operations per unit <blank>

aconz2on TensorFlow: open-source library for machine intelligence

> This open source release supports single machines and mobile devices.

Can someone clarify if "single machines" means the Apache license only applies to single machines and not distributed systems?

Sidenote: I wish every open source project had a release video.

aconz2on Crazily fast hashing with carry-less multiplications

Lemire's work always pops up in regards to high performance or data compression. The paper is interesting and I learned about a new field of math. I especially admire the FOSS implementation of the theory, which is often missing from many academic papers.

Makes me think there's a lot more improvements to be had with the much larger and specialized instruction sets we're seeing nowadays.

aconz2on Software Is Smart Enough for SAT, but Still Far from Intelligent

Read the title and had a different SAT in mind before reading the article -- pretty funny.

> "They assured me they have several layers of security, so the results can’t be hacked into."

That's what they all say.

aconz2on Ask HN: Who wants to be hired? (July 2014)

Location: Outside Washington D.C.

Remote: Absolutely

Willing to relocate: Probably

Technologies: Clojure[script], other languages but I prefer Clojure, communication, problem solving, persistence

Resume: Nothing huge but can share upon request

I love thinking, learning, coding, and climbing. Hard problems make me work hard. Interests are very broad. Would enjoy talking to anyone. Cheers.

aconz2on Plan 9 ported to the Raspberry Pi

I don't think it's a good choice to link directly to a file like that. Perhaps an article on the release would have been better.

aconz2on A Tour Inside CloudFlare's Latest Generation Servers

Sweet write up. I'm curious as to how CloudFlare's needs are similar/different from other companies (i.e. Facebook, Google, Twitter etc.). It seems to me that there would already be quite a lot of iteration and therefore experience/knowledge for what the best set-up would be? Though a large portion seems to be with new hardware coming out.

aconz2on Show HN: Introducing Q.js, a library for modern web apps

The internet does not need another 5000 sloc JS library attempting to solve every problem in one file. Please put your effort towards improving upon other, focused libs.

aconz2on Why mobile web apps are slow

over 180 network requests and over 40 scripts, maybe the author needs to learn a bit more about best practices on the web before standing on his soapbox. and quit bolding things mid-sentence.

aconz2on Your Cardio Routine Is Making You Fat

leading questions, over-generalizations, unsupported claims. its articles like these that spread like viruses on the internet and leads to lots of poor informed people.
