This is certainly odd considering how far we've come in embracing semantic markup and styling.

daturkel··on Rolling Stone's investigation: “A failure that was avoidable”
Several other reads for those looking to learn more about the situation or hear commentary:

The licensing would be every bit as justified if the gear were cheap. This is how he makes his living, he's under no obligation to give it to anyone for free.
daturkel··on The Ghost in the MP3
This was posted almost a year ago and enjoyed a decent conversation in the comments [0]

I'll repeat my comment from the time:

"For what it's worth, the presence of seemingly significant signal in the difference between the original and compressed tracks does not necessarily mean that significant sonic/perceptual loss has occurred. Operating correctly, the encoder is designed to cut not just sounds that the human ear cannot hear in general (e.g. sounds above 22kHZ) but also sounds which may not be perceptible in context (e.g. the quietest signals in a loud section). So if you find something beautiful about the ghost tracks (and I think there is something beautiful to find), don't immediately jump to concluding that mp3 is awful for cutting these sounds—they might be hardly perceptible when added to the mix.

Of course, at high-compression rates mp3 does begin to significantly degrade fidelity.

Edit: all of this is not to put down the project—I still think it's pretty cool as art and as a demonstration of the encoder, I just didn't want people to think that this was some sort of massive failing of mp3."

daturkel··on Google Glass sales halted
Glass actually offloads most of the work to your phone, rather than fitting all that hardware inside the frame.
daturkel··on Amazon Echo
Edit: I missed this: "Plus, Echo is Bluetooth-enabled so you can stream your favorite music services like Spotify, iTunes, and Pandora from your phone or tablet," which obsoletes some of the below. The point on monophonic audio still stands.

Out of curiosity, are you already embedded in the amazon cloud music ecosystem? I'm one of those luddites who still has a library of mp3s—I don't want to have to figure out what I can or can't get on some compatible streaming service here. That would be a lovely feature—if it had an aux-in port or bluetooth compatibility so I could still use it as a dumb speaker. Smart TV's still have inputs, e.g.

Additionally, if I'm not mistaken, it's monophone? Dual-driver, but only one "360-degree" channel of some sort?

daturkel··on Perceptibility of Lossy Audio Encoding as a Signal Detection Problem
I'm a fan of xiph but hadn't seen these two before, thanks for the heads up.
daturkel··on Perceptibility of Lossy Audio Encoding as a Signal Detection Problem
Hey, as I mentioned in my response to klodolph, I used 128 CBR because I knew it would likely not be transparent and wanted to demonstrate false positives, hits, misses, correct recognitions, etc. I wasn't trying to make some authoritative critique of MP3 just because it's low settings are indeed low quality.
daturkel··on Perceptibility of Lossy Audio Encoding as a Signal Detection Problem
Hey, thanks for the feedback! Some of your criticisms point out things which exist mainly because the piece was originally written for a class assignment. e.g. Digital audio was not covered in the course, so I added some information in order to better provide background for the detection theory stuff, which was in the class (and also to make the article more self-contained for the reader unfamiliar with that material). Naturally there is nothing groundbreaking in that summary, but I thought I did a decent job of helping the reader with the legwork of understanding the principles. Additionally, the references are in APA format which was required for the class but, as you point out, is not ideal for the web. I will likely tweak the web version when I have a chance so it's a little more easily navigable.

The fact that the residual spectrum is uninteresting I totally acknowledge; that was admittedly an afterthought. I'm going to check out your hydrogenaudio link for details on how to better that section/figure.

As far as the fact that I only used MP3—that was kind of the point. I wanted to pick a seemingly low-hanging fruit so that I would have some nontrivial results to work with (i.e., cases where I could hear the difference). If I'd used high bitrate AAC and it was entirely transparent for my ears 100% of the time, I wouldn't be able to do much talk about false positives and hits and misses—talk which was ultimately the meat of the assignment, and thus of the article. The goal was, as I say in the "nota bene" at the top, not to say "Hey, look how unreliable MP3 128 is at being transparent," but rather to use MP3 128 to demonstrate the concepts of transparency and compression perceptibility.

As far as converting MP3 back to a WAV for ABX playback, I hadn't heard of that but I have to think that it would have made little to no effect for my test. I have a solid state hard drive so had no disk noise, and I did not hear the cpu fan on for either type of playback. It is something I'll consider for the future.

Again, I appreciate your feedback and thanks for taking the time to comment!

daturkel··on Lab Notebook: Single Pixel Camera
I'm not the author, but it seems like you're certainly right. Here's an example from the wiki page about how a single-pixel camera utilized notions of compressed sensing: http://en.wikipedia.org/wiki/Compressed_sensing#Photography

I guess applying compressed sensing techniques would mean making assumptions about your image which allow you to fill in some of the blanks created by the incomplete angle and position coverage (i.e. the fact that the system is underdetermined). If you could somehow assume a certain redundancy, you could probably make guesses about what goes in the spots that didn't get well-covered.

daturkel··on The Nobel Prize in Literature 2014
The Nobel Prize in Literature always has been and likely always will be a controversial category. No doubt any book-lover can name a handful of authors that ostensibly deserve the honor, but there are a lot of great authors and only one Nobel Prize per year! For what it's worth, Pynchon is notoriously reclusive and not the kind of person who's likely waiting for the spotlight that the Swedish Academy would be shining. As things stand, the film adaptation of Inherent Vice seems to bring promise of greater attention to his work that it has received in a while now.

We don't currently have ebooks available for our Modiano titles unfortunately, though reprints are already being scheduled so it's possible ebooks might be a part of that. I can't personally make any promises. Edit: The office is very much aware of the interest in an ebook edition!
daturkel··on The Nobel Prize in Literature 2014
A heads up that Honeymoon, Missing Person, and Catherine Certitude (a children's book) by Modiano are all available from David R. Godine, Publisher, for those looking for English translation. [0] To the best of my knowledge, English translations of Modiano are actually shamefully rare and these might be the only available editions at the moment.

Disclosure: I'm an intern at Godine.

daturkel··on Show HN: Mojulo – Pixelated Math Rendering Sandbox Toy
Thought this came out pretty well:

http://maxbittker.github.io/Mojulo/#cip0aW1lKih0aW1lKnNpbih4...

Speeding it up (increase the first "time" to "time^9") you can see that it eventually "heats up" all the way to black, but it's a nice journey.

Edit: also this one has a nice strobe. You can strobe any pattern you make by replacing a time with some variant of B*sin(time/C) where B and C are appropriately chosen coefficients.

Is there support for alternate math fonts (not sure what the proper term is) like \mathbf, \mathcal, \mathbb? Couldn't get it working. Looks fantastic though.
daturkel··on Why Do We Say “Big Red Barn,” But “Red Big Barn” Sounds Wrong?
Came here to post the same link. English adjective order is one of those things that we're never taught as speakers of English as a first language, but I'd imagine it's taught to those learning it as a second language.

daturkel··on Pinboard 2014 Expenses
Pinboard is one of a few services I happily pay for. Honestly, I'd probably pay a subscription price for it. I've got 1041 bookmarks, it's fast, searches and tags flawlessly, the unread functionality is super useful, and I've got some (unofficial?) android app that makes it a snap to use with my phone. Keep up the great work.

daturkel··on The Skip
For those who don't know, Paul Lamere, the author, is a really cool guy that works over at The Echo Nest (recently acquired by Spotify). I had the pleasure of meeting him and chatting with him a few times last summer while I was interning there and he's basically a music+tech genius. Lots of the echo nests coolest api demos are all his doing. I'd link to stuff but I'm on my phone, but definitely browse through his blog. If this is your area of interest, Paul is the guy to read.

edit: on my comp now, so I can add this link to some cool EN API demos, many of which are Paul's if I recall correctly: http://static.echonest.com/labs/demo.html

I would contribute to this, both in terms of donating to see this happen but also to the content and/or the community. Silly as it sounds, my least favorite thing about HN is the startup content---i don't care about agile this or lean that or pivoting or whatever, I'm interested in people "hacking" on passion projects, making cool tools, and breaking stuff.
