ar7hur··on Show HN: Duckling – Open-source datetime expression parsing
Probably too much :) All our backend is Clojure, all our new web developments are in ClojureScript (with React and Om). The only places we're not using Clojure are iOS, Android and Raspberry/embedded linux. We're using Rust more and more for the latter.
ar7hur··on Show HN: Duckling – Open-source datetime expression parsing
Thanks! Yes we should probably relax a little bit the lexical analysis to cope with typos, thanks for your feedback.

Here is our blog post announcing the project: https://wit.ai/blog/2014/10/01/open-source-parser-duckling

Feedback welcome!

ar7hur··on Billionaire ordered to unlock Martin's Beach but won't be fined $20M
Yeah that's the funniest thing of the story. Before VK tried to block the beach access only a few surfers came every week, and few people knew about the beach. Now everybody knows and will flock to it!
ar7hur··on Show HN: ParseHub – Extract data from dynamic websites
Looks powerful. Just curious, how does it compare to Kimono Labs?
ar7hur··on After Surgery, Surprise $117,000 Medical Bill from Doctor He Didn't Know
To fellow startups claiming to "change healthcare": this is not about nicer online forms. This is about destroying this.
ar7hur··on I was asked to crack a program in a job interview
Unfortunately I think it's not so simple

    ";" is surrounded by space left and right
    ":" has no space on the left in English, but it has one in French
ar7hur··on Voice Interfaces
Dustin is right: a truly pleasant user experience would necessary involve continuous listening (without hotword à la OK Google), as well as leveraging the user context much more than what Siri or Google Now do today. See for instance the vision depicted in the movie Her [1].

Beyond Google or Apple, a few startups (like us at wit.ai) are hard at work designing building blocks to help developers solve these problems.

ar7hur··on Show HN: How to Annoy Your Coworkers for $42 Using ClojureScript and Rust
Wit.ai team here. We've been thinking about it actually, and webhooks as well. Stay tuned!
ar7hur··on Alfred Wins TechCrunch Battlefield SF 2014
In this so-called shared economy, intermediaries such as Uber, Homejoy, Airbnb, etc. already take a 20% to 30% cut while trying to remain only an app, or technology layer (as they claim when regulators try to intervene). That may or may not be justified. But having yet another app layer take its cut ($100/month!) on top of that seems unbearable. Or maybe bearable just in Silicon Valley.
ar7hur··on IBM Sees Broader Role for Watson in Aiding Research
+1. IBM must regain control over their PR people, speak less and do more, or they will lose any credibility with developers.
ar7hur··on On the foolishness of “natural language programming”
Natural language is ambiguous: one phrase often has multiple meanings. That’s the result of many thousands of years of evolution, and it’s actually very efficient. If we had to be always explicit, our phrases and sentences would be much, much longer — and boring. When A says something to B, A makes assumptions on B’s context, common sense,beliefs and knowledge. The verbal message itself just contains the minimum information needed, on top of this pre existing information, in order for B to get it.

Natural Language can be seen as a very efficient compression algorithm. The phrase the speaker chooses is the shortest message, given the context of the receiver.

Programming a computer with Natural Language is incredibly difficult, because Natural Language alone, without the context it is built upon, really lacks much of the information the computer needs to operate the program.

ar7hur··on Ask HN: YC W14 When we could apply?
Probably in October (and it will be Winter 2015 not 2014)
ar7hur··on Help Wit.AI (YC W14) choose a logo
We've been struggling for a long time about our logo, any vote and/or opinion/suggestion is more than welcome!

Wit.AI [1] is an API that makes it easy for developers to create apps that users can talk to.

ar7hur··on Google’s $1B purchase of Twitch confirmed
True, but if the price is actually as high as $1B, it means that "other concurrents" at least tried to do something about it!
ar7hur··on Product/Market Fit (2007)

    There is one high-profile, highly successful software entrepreneur
    right now who is burning through something like $80 million in venture 
    funding in his latest startup and has practically nothing to show for it 
    except for some great press clippings and a couple of beta customers
I'm wondering who Marc is talking about? (it was in 2007). Any idea anybody?
ar7hur··on YC Portfolio Stats
Very impressive.

I'd love to know how many out of the 716 companies funded so far are still in business per se as independent entities? And among those that are not anymore, what was the exit (successful exit vs. soft landing / acquihire vs. death). I suspect it's really hard to track though, and somewhat subjective.

ar7hur··on Ask HN: Urgent connection to Twitter support
To put things in context, Israel killed at least 24 people in Gaza today [1], including children. Did they have access to Twitter, let alone any telecommunication mean, let alone food and water? Sorry, but I really don't see how your twitter account being rate-limited or whatever has the slightest importance in this tragedy.

ar7hur··on Stop The JerkTech
The problem is it's not your parking spot, but public property.
ar7hur··on Ask HN: Did you get "never have to work again rich" through software?
I'm absolutely fine with your lifestyle and understand your happiness, but you have to realize that the 3 assumptions it's based on, that you have to be "young, healthy, and single", are all highly mutable.
ar7hur··on Investor Updates
Great post Aaron, but I disagree with that piece:

     [...] the best founders would write good and frequent updates because
    it reflects their own processes and attention to metrics and consistent 
    growth.
I don't think the correlation is between "best founders" and "frequent updates". I think the correlation is between "successful startup" and "frequent updates".

When your company is doing well, you are happy to report about it. On the contrary when founders feel that their startup is going down, most of them dig a hole and hide there, hoping somehow to resurface when their issues will be solved (which is not of course what we should do... but we do it...).

ar7hur··on How we raised capital one month after launching
If PG sees your chart without y-axis label on the top of the post, you're dead man :) What is it?
ar7hur··on Tell HN: My startup is making money and I don't know what to do
> (~40% w/w growth, 100%+ m/m growth)

You should fix this enormous mathematical inconsistency, or everything else you claim is suspicious.

ar7hur··on Quickly – Giving email a mind of its own [video]
Cool project.

If I understand, it learns what emails mean and what actions should be triggered across all users. So I guess it must store my emails and actions somewhere, to participate to this across-the-board learning. I wonder if users will be concerned about this.

ar7hur··on Turing Test Success
More likely 1E9
ar7hur··on Ask HN: Who is hiring? (June 2014)
Wit.AI (YC W14) (https://wit.ai/jobs) - fulltime, Palo Alto

We are building the AI platform that helps 3000+ developers create apps that understand human language [1].

We’d like to hear from you if:

- You are a full-stack software engineer: you know how to build entire projects/features from Web UI to core ML algorithms

- You are curious: you can’t resist the urge to solve hard problems, learn new domains, try new things, and you don’t take “that’s impossible” for an answer

- You have done many mistakes (we know you won’t make them again)

Experience in NLP/Speech/Machine Learning is not required (and actually we also like when you don’t have any: curiosity > knowledge). Being ready to learn/do whatever it takes to succeed, from Clojure to Javascript to supporting users to C to assembling furniture, is expected though.

Check out https://wit.ai/jobs for details

Whatever happens in the courtroom, Chahal has lost already.
ar7hur··on Explanation of 44.1 kHz CD sampling rate
I see what you mean, but since the 1970s speech researchers have been splitting seconds into 10ms or 25ms intervals, that's not my decision. They could have started from any duration but they haven't. And you could start to express time with the Aztec calendar if you wanted. But you won't.
ar7hur··on Explanation of 44.1 kHz CD sampling rate
What you say actually makes no sense whatsoever. Why are you talking about 1 second windows? If 44100 can be decomposed easily in small prime numbers, it means that you can split 44100 into windows that are themselves products of small prime numbers.
ar7hur··on Explanation of 44.1 kHz CD sampling rate
Almost all ASR engines use 25ms windows, not 10ms (they typically overlap and are processed every 10ms).
