ar7hur··on Explanation of 44.1 kHz CD sampling rate
Also, the fact that 44,100 can be factored as 2^2 * 3^2 * 5^2 * 7^2 makes it very efficient to do Fast Fourrier Transforms on moving windows. Which we do a lot in Speech Recognition and DSP in general.
ar7hur··on DoorDash (YC S13) Raises $17.3 Million From Sequoia To Expand On-Demand Delivery
Congrats to the team!

I respect what you've done so far, but I can't help wondering how investors can base their analysis on an experiment restricted to Palo Alto, Mountain View and San Jose. From what I see, the bulk of orders (in $) are from fellow startups ordering lunch and dinners. Where else is the world (except SF and maybe NYC) do so many companies, in such a small geography, order so much food from restaurants?

I'm not saying it's not a good business. I'm wondering if there is really room for growth (a growth big enough to justify the huge series A valuation) outside of very specific geographies.

ar7hur··on Why is San Francisco public transportation so bad?
Because who cares? We have our shuttles to the valley and Uber for the parties!

ar7hur··on Show HN: Build Spanish Speech Interfaces with Wit.AI
OP here. We are about to release many new languages. Any feedback from Spanish-speaking devs is much appreciated, thank you!
ar7hur··on The little things I learned in the valley
> Palo Alto, Mountain View etc. are no more part of Silicon Valley

Seems somewhat exaggerated to me. There's definitely a shift from the valley to the city (and Palantir eating up all available space in PA sure catalyzes this process), but I wouldn't say PA/MV are "no more part of SV".

ar7hur··on Silicon Valley Billionaire Battles Surfers Over Beach Access
YC W14 startups have all received this investment from a fund "YCVC" that includes KV (I know this first hand, we are one of them!). That doesn't mean any of us chose KV.

That being said, I want to moderate my comment. Until now, the situation is still under control, but it could become worse and then start to be a PR problem for KV. It's still time for them to do something.

ar7hur··on Silicon Valley Billionaire Battles Surfers Over Beach Access
Regardless of the law, I just don't understand why Khosla is going into this PR disaster. Which entrepreneur who has a choice (and 99% of successful entrepreneurs have a choice) between Khosla and another VC would choose Khosla after that?
ar7hur··on Moving On
Kudos to David Marcus for this smart, no-bullshit reaction. We need more human material and less PR shit from CEOs.

I understand that junior employees can sometimes go publicly against the company they just left, but that's really not something you expect from somebody who is supposed to be a seasoned, professional exec. Good luck for the rest of your career, Rocky, you'll need a lot of that -- which CEO is the world is willing to hire you again?

ar7hur··on Proposed Mexican Telecom Law Would Be a Disaster for Internet Freedom
Unfortunately as a consequence to Carlos Slim's quasi-monopoly on telcos, Mexico has already the highest Internet access price in the world. I'm wondering if this law is not another attempt to lock down the system.
ar7hur··on Google Glass is now available to everyone
I've had a pair for the last 6 months. Honestly at this price point ($1500), you must really be a geek to be willing to buy one. IMHO it's not ready for rollout. The limited voice UI and the battery life make it useless for actual consumer usage.

Let's see 6 months from now if the app is still around -- personally I bet it won't.

ar7hur··on Show HN: An open-source, Raspberry-Pi-based Siri alternative
Hi Kyle, Wit.AI team here -- thanks for suggestion (1) :-)

Actually our typical latency is less than 0.5s if you stream audio to the API (instead of waiting until a silence, then sending a WAV file). Also, we are working on an embeddable client (you would still use Wit.AI online to train your model, but then they can run locally on your Raspberry Pi).

ar7hur··on Show HN: An open-source, Raspberry-Pi-based Siri alternative
It's mostly a question of training data. Google trains its acoustic models on thousands of hours of annotated audio samples. It's very hard of an open source project to i/ get enough data ii/ have the computing power to actually train with it.
ar7hur··on Show HN: Siri, open the garage
Very cool hack! I would never have thought about implementing each command ("open the garage") with a specifically named app ("the garage"). I guess it'll work until you already have a (real) app called like the thing you want to open :)

An easiest way would have been to use Wit.AI API [1](disclaimer: Wit team member here). You can create any command in minutes and use any device capable to stream audio to the API (including your iPhone) as client. I'd be interested to have your feedback if you have time to check it out!

ar7hur··on Microsoft unveils Windows Phone 8.1 with personal assistant Cortana
Did you try Wit.AI? [1] It's cross platform and totally open: you can create any voice command you want by just providing a few examples of what you expect. Then the API turns speech (or free text) into JSON.

ar7hur··on Top Startups From Y Combinator W14 Demo Day
Hi, Wit.AI team here. Thanks for your feedback.

We also have a free community plan: if you agree to give back to the community by sharing your training data, then Wit.AI is free for you.

That being said, we are just getting started and we'll adjust our pricing after we get more developers' feedback.

ar7hur··on Ask HN: Will soon have lots of time and little money – how to spend it?
If you can do your work remotely then pack a small backpack, and travel around the world. No flights, just cheap road transportation, trains, boats, where you'll meet ton of people you'd never meet in your life. Go to South America, to Asia, to Africa, if you're smart and tough you can travel a year on a $15K budget.
ar7hur··on Show HN: I made my website/resume voice controlled
Very interesting Ben! Did you have a look at https://wit.ai ? It's an API that encapsulates both speech rec and semantic interpretation.
ar7hur··on Dear AirBNB, No thank you for the XXX Freak Fest
So you think you can make $710 renting your studio for two nights without any risk of this kind of thing happening? Wake up, man. No risk, no reward.
ar7hur··on Home automation using Node.js, raspberry pi and tinkerforge
Very interesting writeup, that's a cool project.

Now to make it still cooler and Jarvis-like, you can add voice commands with the Raspberry Pi. Somebody did it here [1] using the Wit Speech API [2]

ar7hur··on Microsoft Is Interested in Buying Stake in Dailymotion
I certainly agree there are a lot of good ideas and neat projects starting in France -- what I mean is they have trouble growing into big successes.

That tells a lot about France's so called "successes" (I'm French btw)
