Jukebox - <AUTHOR> https://openai.com/blog/jukebox/ <comment><USER2> I think people in the comments are completely missing the point of this work. As I understand it, and take this with a large grain of salt because I haven't read the paper, the idea of Jukebox is to take a certain style of music by a certain musician and have the algorithm sing, karaoke-style, the lyrics that are listed in the examples to the tune of that music. Think of it as a really jazzy version of Google text-to-speech. The lyrics are not written by this algorithm, it's just singing in the style of Sinatra or Lady Gaga some words that have been prewritten. It's fun to listen to and really amazing to watch it read the lyrics and decide where to put emphasis, and where not to - dragging out certain words and letting others be mumbled. Comparing this to something like IBM's rendition of a "Bicycle built for two" showcases how utterly mind-blowing this work is!

Finally, can we stop treating ever single piece of work by neural networks as a "failure" because it isn't GAI? Just because it doesn't "say something about the human experience", doesn't make it bad engineering. It's hilarious how as soon as there's some new AI work done everyone starts wailing, "where's the humanity!"

Lay-people think AI refers to ALife.

Most of the talking heads would be immediately satisfied—giving none of these complaints—if they were shown an "AI" program that responds to stimuli by entering emotional states, and which learns to associate stimuli with the emotional states it has been in in the past, such that those stimuli will then become triggers for those states, and for memories associated with those states.

Such an agent wouldn't even need to use ML techniques, necessarily. It'd just need to be a high-concept tamagotchi that can respond to operant conditioning. That would already be an advance over the state of the art.

But, AFAIK, nobody's really working on ALife in the sense of "making an individual agent with a complex-enough internal model that it can statefully respond to you the way a pet does." ALife is only really studied at the very low level ( _C. Elegans_ connectome simulation) or the very high level (sociological/economic simulations using simple goal-driven agents); nobody's really working in the space "in between." (Except for the people trying to make chat bots seem friendlier, but they're mostly trying to fake it, rather than creating actual persistence-of-memory.)

I wonder why nobody's interested in medium-scale ALife research these days? It used to be a hot topic, back when it was conflated with robotics under the banner of "embodied cognition."

<comment><USER4> So basically, most talking heads would be better off playing The Sims. They'll have agents there that enter emotional states in response to stimuli. Even though it's just a fuzzy state machine.

Now, is A[rtificial] Life the correct term to use here? I feel it isn't - I'd expect ALife to be more concerned with implementing simulacra of bacteria or worms in silico, not with reasoning or emotions.

<comment><USER3> ALife is fundamentally concerned with the research on the kind of _control systems_ that govern how organic life responds to stimuli, how those systems plan in order to maintain long-term homeostasis, how they select goals, how they allocate attention, etc.

One might say that ALife is to an event loop as AI is to a one-time query- response. AI can _evaluate_ , but you need an ALife system in order to "think" in a continuous way.

There's really no sense in which an ALife researcher cares about recreating a full-fidelity model of _biology_ in silico; the point is to specifically study the _thinking and decision_ process of real agents, and figure out how to model those, in a way that the model makes the same _series_ of decisions the real agent does in the same situations (and, therefore, must also be keeping and updating analogous internal state to the kind the real agent keeps.)

Some of those models are attempts to recreate real brains/nervous systems, but these models aren't fundamentally biological. A "low level" connectome simulation doesn't contain any model of cellular inflammatory response, cellular waste and its clearance, etc. It's basically just a brain-as-actor- model with neurons as stateful processes and electrochemical signals as messages.

An ALife researcher cares about as much about biology below the level of intracellular pharmacodynamics (sodium channels et al), as a race-car-chassis engineer cares about physics below the level of fluid dynamics. They don't need to go any lower, because they've found an encapsulating abstraction that makes all the predictions they're interested in making, without needing any lower-level information.

The June sun was still high in the sky, and in the sun-filled court below, a monstrous woman, solid as a Norman pillar, with brawny red forearms and a sacking apron strapped about her middle, was stumping to and fro between a washtub and a clothes line, pegging out a series of square white things which Winston recognized as babies' diapers. Whenever her mouth was not corked with clothes pegs she was singing in a powerful contralto:

      It was only an 'opeless fancy.
      It passed like an Ipril dye,
      But a look an' a word an' the dreams they stirred!
      They 'ave stolen my 'eart awye!

The tune had been haunting London for weeks past. It was one of countless similar songs published for the benefit of the proles by a sub-section of the Music Department. The words of these songs were composed without any human intervention whatever on an instrument known as a versificator. But the woman sang so tunefully as to turn the dreadful rubbish into an almost pleasant sound. He could hear the woman singing and the scrape of her shoes on the flagstones, and the cries of the children in the street, and somewhere in the far distance a faint roar of traffic, and yet the room seemed curiously silent, thanks to the absence of a telescreen.

Then we hear it in

\- social media creators make their own music to go with their funny videos. Cheap theme music for streamers and podcasters.

\- Advertising. Shopping centres make lyrics that advertise products and play them to you as pop songs. Some bubs make their own songs.

<comment><USER7> The future will be AI lawyers battling for rights of AI generated music in the style of deceased artists on behalf of AI media corporations at the expense of robotic listeners.

Before all of this, we'll probably see improvised bands of deceased artists playing together AI generated music in their own style, not to mention long dead actors appearing in new movies etc. AI technology is going to give law firms a lot of work in the future.

</comment></comment></comment></comment><comment><USER8> Boy, the comments on this thread are ridiculous. SO many people saying "bleh, this is terrible, music is obviously out of the reach of ANNs, etc etc etc." If you've been following this space, this research is nothing short of fucking mind-blowing. Can you use these outputs as final radio-ready songs? No, they're heavily bandpassed, and the overall composition either feels 'unfinished' or nonexistent. But criticizing it on those grounds _completely_ misses the point.

There are so many people here saying "music can never be generated by AI because, I don't know, creativity requires magic and only human souls have magic". Really? I kind of wonder how many of these people have actually done something creative. Creativity is such an amazing example of a large, densely connected neural net in action, when you let it start making unusual associations via what is sometimes called "lateral thinking."

I feel like people have already lost sight of how utterly incredible it is that we can generate anything like this, or Deep Dream, at all. They are _incredibly_ creative.

</comment><comment><USER9> This is really great work. :) On a slightly tangential note, I understand why they chose an audio representation over symbolic, but I think that training the latter is more useful (commercially speaking). Would love to be able to get a track rolling quickly just selecting an instrument set and tweaking some AI parameters and then hand-tune it from there (yes, this greatly detracts from the "art" of it but sometimes I just want to see results quickly). Of course, to do this effectively, you would also have to analyze on an audio level (at least per instrument) so that the usage and timing of instruments could be better understood.

</comment><comment><USER10> In my view, attempts like this misunderstand much of the point of music. That is, to communicate aspects of human life that are deeply interwoven with facts and experiences outside of the music itself.

I don't see how any of that will be possible before we have some kind of general AI, and in the meantime I think these attempts will continue to be semantically empty, even unsettling in their emptiness.

<comment><USER11> > In my view, attempts like this misunderstand much of the point of music. > That is, to communicate aspects of human life that are deeply interwoven > with facts and experiences outside of the music itself.

I actually think you've missed the point. These attempts do not aspire to communicate aspects of human life at all. They're simply scientific and engineering endeavors that seek to answer less profound questions like: "Can computers generate music?" (Yes) and "Can computers generate music that is enjoyable to listen to?" (Not yet)

To go one step further: There are glaring and obvious technical faults in many of the generated samples (this isn't a criticism, they're better than past work!). I suspect that if you are feeling unsettled by these songs it's because of those flaws and not because they are "semantically empty".

<comment><USER12> > These attempts do not aspire to communicate aspects of human life at all.

Of course not. They, just like enough humans do already, imitate the results of "having an adventure of the soul".

> "Can computers generate music?" (Yes) and "Can computers generate music that > is enjoyable to listen to?" (Not yet)

And we're talking about the question "should they?", which science can't even attempt to answer. "Play from your heart", and all that; not even best-selling artists pumping out mediocrity are above that criticism, even when they do it according to the best of their ability and conscience, and even when it makes people "happy".

</comment></comment></comment><comment><USER13> Holy crap.

That's not just a passable lyric. I think it's downright _good_.

<comment><USER14> Just know that: much of the stuff OpenAI and other research orgs put out (including mine) are heavily cherry-picked. Most of the time its pumps out gibberish, but in the off chance it doesn't it gets used as marketing material.

<comment><USER15> All you have to do is click through to see all the samples and it becomes clear how incredibly cherry-picked the ones on the front page are. It is a cool project but it is very clear how much work this technology will need before it is useful in any application.

<comment><USER16> Cherry-picking is exactly what artists do best. They will want this technology as a new tool in their toolbox. I expect some future genre of music using it's successor (like autotune).

</comment></comment></comment></comment><comment><USER17> Can anybody explain why the researchers are attempting to generate the whole song as a single waveform, as opposed to wiring generated MIDI into some instruments and separately a singing algorithm (perhaps a bit easier than the whole bulk work)?

<comment><USER18> We did work last year on MIDI alone - [https://openai.com/blog/musenet/](https://openai.com/blog/musenet/) and some early work now on conditioning the raw audio based on MIDI (early results at the bottom of the Jukebox blog). Agreed though there should be interesting results from modeling different blends of MIDI, stem, and raw audio data. Raw audio alone gives us the most flexibility in terms of the kinds of sounds we can create, but it's also the most challenging to get good long term structure. Still lots more work to be done!

<comment><USER16> Something like MOD/XM music comes to mind.

</comment></comment></comment><comment><USER19> This might be onto something!

Just listen to this from 30s: [https://soundcloud.com/openai_audio/pop-rock- in-the-6355437/...](https://soundcloud.com/openai_audio/pop-rock-in- the-6355437/s-91Av3WRRi4r#t=30s)

Such coherent and pleasing melodic phrases in the style of Avril Lavigne. I thought it could be copying wholesale from a song unknown to me. Nope. Shazam doesn't get it.

This can revolutionize song writing/composition/production and soon music listening/consumption.

<comment><USER20> Note that the lyrics are part of the input to the Jukebox neural net, so I assume they used the lyrics of an existing song here. Nothing stops someone from using a lyric-generating neural net with Jukebox though. (It's probably more useful that the lyrics aren't produced by Jukebox because it means you can easily swap out the lyric-generation part or manually tweak the lyrics.)

<comment><USER8> The lyrics are generated by a separate model, but they're "co-written" (cherry-picked) by the authors.

<comment><USER20> Only one category of the samples on the main Jukebox page are described that way. The rest of the samples were pre-existing lyrics, so the song linked above might also have had pre-existing lyrics.

</comment></comment></comment></comment><comment><USER21> I did a little bit of work along these lines using gwern's folk music AI model: [https://soundcloud.com/theshawwn/sets/ai-generated- videogame...](https://soundcloud.com/theshawwn/sets/ai-generated-videogame- music)

No lyrics, but the song structure is there. The main problem is that all the pieces end abruptly. It's also midi, not waveform generation, so it's closer in spirit to OpenAI's MuseNet than to Jukebox.

It's also not entirely AI. I didn't modify any of the notes, but I changed the instruments until it sounded good. IMO it's much more interesting to use AI as a "tool you can play with" rather than "a machine that spits out fully-formed results."

</comment></comment><comment><USER24> I think work like this will really bring a whole new life to a lot of video game music. Today, we see some really great composers making cinematic-level music for video games, which is great. What worlds often miss is ambient sounds, a radio as you're driving or something that reacts to how you act (Actions per minutes go up, maybe the tempo does too?) without having to compose a TON of music.

</comment><comment><USER25> From the GitHub repo:

"On a V100, it takes about 3 hrs to fully sample 20 seconds of music."

That might make building off this project out of reach of the average engineer (you certainly cannot build that into a Colab notebook), although that necessary amount of compute is not surprising.

<comment><USER26> Isn't that superhuman?

I would guess that on average, it takes a professional more than 36 hours ((4×60÷20)×3) to make a 4-minute audio track with original music based on given lyrics.

<comment><USER27> I don't really see the point of this comparison. Composing, arranging, and producing a song is not a benchmark you can profile against; musicians are not performing some kind of music compute that produces a set number of music units per hour.

Speaking from my own experience, I've had tracks that took months to complete, and I've had tracks that I got to probably 90% completion in under an hour. I would propose that there's no meaningful definition of "superhuman" for creative efforts.

<comment><USER8> Agreed. Although "professional" pop production does tend to be somewhat involved, it doesn't have to be, and total time spent could vary so radically as to have essentially no correlation to anything else.

<comment><USER29> Interesting how the AI turns "wouldn't get" into "never gonna give" at 0:15, maybe because of overfitting ?

</comment></comment><comment><USER30> Bit of a pity that most of the samples are only a little over a minute. Hard to tell if the thing can hold a structure over a longer time — frankly most of what I've heard so far leaves the impression of 'shovelware'. It seems to be pretty good at intros and shortish verses, however many tracks end too soon after.

I found one 'Toots & Maytals' track of >3 minutes (perhaps it's more straightforward on desktop but eh). It started great, but devolved into MCs mucking around right at the end of the first stanza, and never got back on track. I guess teaching the software about positions in lyrics would indeed help. But it did keep putting out reggae-ish sound.

Would be interesting to hear what it would do with free jazz music—without long intros this time. Ironically enough, if you know nothing about music theory but listen to plenty of jazz, it's not had to imagine some 'new' free jazz in your head—probably in the spirit of 'my son could make this'.

Ramones' 'punk' and Nirvana's 'grunge' seem to be completely mistaken (not even remotely close like their tracks in 'punk rock' and 'rock' respectively).

I wonder if karaoke videos would be a useful source of data here. Granted, karaoke tracks are usually covers, but some of them are very faithful to the original.

</comment><comment><USER35> It's kinda telling to me that all the examples are soundalikes on sorta famous individuals. Totally valid of course, but among all the different musical styles there's no dance music; is it because without any distinctive vocal or orchestral flourishes, there isn't much that the algorithm can latch on to?

Maybe what we're hearing is the distillation of what makes these individual artists/composers distinctive/recognizable but without the musical substance, rather like a floppy rubber mask that resembles a specific individual but lacks an animating interior force. Kinda like how electronic synths/sequencers instruments make it very easy to come up with distinctive flourishes or sounds that make great ear candy, but it takes much longer to develop a solid sense of groove, harmonic motion etc..

</comment><comment><USER36> So a lot of this sounds muffled and compressed... I wonder if something like the equivalent of a super-resolution or denoising autoencoder for music would work here as a post-processing step.

</comment><comment><USER69> In no way do I mean to take away from the really great work of these researchers, but there is one thing here that people should be aware of. By using karaoke style lyrics, this scientific study invalidates itself and the credibility of those that went forward with publishing it. By reading the lyrics while listening to the audio, the brain will automatically convince the listener that the audio result is better than it is. What is the proof for this? Well, look no further than the infamous Yanny/Laurel audio clip. When you read the word "Yanny" or "Laurel" at the frame rate of the audio, your brain switches between two different auditory suggestions.

[https://en.wikipedia.org/wiki/Yanny_or_Laurel](https://en.wikipedia.org/wiki/Yanny_or_Laurel)

There is also a scientific precedence that refutes these findings, which is called the McGurk effect.

[https://en.wikipedia.org/wiki/McGurk_effect](https://en.wikipedia.org/wiki/McGurk_effect)

[https://en.wikipedia.org/wiki/Speech_perception#Music- langua...](https://en.wikipedia.org/wiki/Speech_perception#Music- language_connection)

These researchers may not be to blame for this, but they really should have been honest in their conclusion.

<comment><USER70> They concluded that their model "is capable of generating pieces that are multiple minutes long, and with recognizable singing in natural-sounding voices." Which part of that is dishonest? I would assert that being able to make sense of the lyrics is a nice bonus but not fundamentally relevant to their conclusion, in that a person can appreciate singing in a foreign language, and recognize it to be natural, without any knowledge of the words whatsoever. Besides speech synthesis in terms of intelligibility is basically solved, that's not really the thrust of what they've achieved here.

And more to the point, a full 815 of the uploaded songs have no pre-written lyrics, so your premise that they are reliant on "karaoke style lyrics" is mistaken to begin with.</comment></comment>


JavaScript at 20 - <AUTHOR> http://brendaneich.github.io/ModernWeb.tw-2015/ <comment><USER5> If you're interested in learning ES6 basics in 20 minutes, this is a great starting point: [https://github.com/lukehoban/es6features](https://github.com/lukehoban/es6features)

Check out this repo, if you have a "little more" free time: [https://github.com/ericdouglas/ES6-Learning](https://github.com/ericdouglas/ES6-Learning)

To be honest, I used to dislike JS not so long ago - it was hard to debug, I had to use strange conventions to write OO code etc. But after learning more about the ES6, react/flux, node, Flow etc. I can honestly say that I really, really like JS. I think that I had negative feelings towards JS because I was using it "the old way" and completely ignored the language improvements & community/ecosystem that grew aroud it. But I learned my lesson :).

<comment><USER6> What other resources did you use? I'm slowly working my way though Programming JavaScript Applications.

<comment><USER5> There is no a single site/book I use, I just search for a topic that I think is interesting. Fore example, lately I've been exploring Promises and asynchronous JS [0][1].

Anyone claiming that JS is the "worst thing to happen to the web" and/or that some other language would miraculously solve all of the problems present in JS should do the following, "Go create it." Don't whine about the barriers and how a new language would never be adopted because "JS is already everywhere." There are plenty of people already trying to solve this problem by actively doing something. I've worked with enough engineers that love to criticize every design choice made but when it comes to asking them what the better alternative is they have nothing to say. They just "know" there's a better way. Well, stop using your intuition based rationalizing that there's a problem and start using your creative and logical faculties to actually solve the "perceived" problem before presenting a criticism. Or at a minimum present a well thought out and actionable direction towards the solution.

<comment><USER8> There are no end of alternatives out there today, from mobile platforms to research languages exploring a myriad of aspects of computer science.

Just let me know when browser vendors are going to break down the two-tiered system, and let us run the legion of alternatives alongside -- instead of under -- JavaScript.

Or, they could take their own medicine, and try and write the browser in JS.

<comment><USER9> > Just let me know when browser vendors are going to break down the two-tiered > system, and let us run those myriad of alternatives alongside -- instead of > under -- JavaScript.

The complexity of doing that would be needlessly high compared to just improving JavaScript. Having to integrate a C++ DOM with a JS DOM is hard enough. Think about how you handle cross-language cycles…

> Or, they could take their own medicine, and try and write the browser in JS.

You mean like Firefox?

<comment><USER10> Works on OSes. We have a choice.

In browsers, the OSes of the web, nope, just a bad language designed in 10 days that resists all attempts to make it not bad.

It doesn't really matter if you like javascript, there's so many people who don't.

Why do you get to dictate whether we can or can't develop on the web? You leave us with a horrible choice, use what we consider to be one of the worst modern languages, or not develop. Why do you get to make our professional lives miserable?

<comment><USER9> > Works on OSes. We have a choice.

The kernel doesn't have a DOM. On the Web, the number of GC'd objects that every "process" has to deal with exceeds the number of file descriptors by an order of magnitude.

Also, you do have a choice: you can compile your favorite language to JS, even low-level ones via asm.js.

> Why do you get to dictate whether we can or can't develop on the web? You > leave us with a horrible choice, use what we consider to be one of the worst > modern languages, or not develop. Why do you get to make our professional > lives miserable?

That's not the choice: you can compile your favorite language to JavaScript. That's what source maps, asm.js, and the like are for. And JS is being improved all the time; it's not static.

Trying to add another language has been tried multiple times and has always failed, because having two languages that both interact with the DOM is much more difficult than just improving JS.

<comment><USER11> Semi-serious question: Other than backwards compatibility, do browsers need to have a DOM? It seems like many web app devs spend more time fighting against the DOM than working with it. Why not just make the browser expose a generic GUI model? Let web devs interact with Webkit or QT directly?

<comment><USER12> Generic GUI toolkits are very often _worse_ than the DOM. I've worked with Swing, MFC, SWT, Android, and iOS, and all of them are significantly more complicated than the DOM is. They do function at a higher level of abstraction, and the two really nice things they give you are components and a sane layout system (solved by WebComponents and Flexbox, now if only all the major browser vendors would just adopt WebComponents...), but in general I've found that iOS development is about 1.5x-2x slower than web development and native Android development is about 3x slower, roughly on par with Swing or SWT. MFC was a clusterfuck, I wouldn't even go there.

The way frontend devs for other platforms deal with it is to specialize in the nuances of the platform and effectively build your app around the capabilities that Google/Apple/Microsoft/Sun provide. That's fine, and makes for a fairly uniform, polished experience if you have good devs, but it significantly restricts the set of apps you can build. The reason web developers like developing for the web is because it doesn't make you a sharecropper in Google/Apple/Microsoft's world, while building a full-featured GUI framework into the browser would.

<comment><USER13> I've found JavaFX's scenegraph approach rather neat. Effectively it borrows from HTML, but where the basic node set is designed to be UI elements rather than co-opting a set that was designed for text documents. It seems to take a surprisingly small amount of code to sketch up an interface.

React's not bad on the web side (especially with Scala.js) but fudging around layouts in components with divs and Bootstrap still feels clunky.

Last time he was playing some zombie video game in the middle of his presentation. He insisted on not killing zombies with a shovel using instead deployable automatic turrets. I'm sure he uses the shovel when he plays alone though. Javascript's is actually growing very well and fast. It's quite surprising how soon it will have everything. In a way it can be compared to PHP - soon it will be a giant toolbox. The difference is that every tool was chosen and added one at a time. It ends up being a very good toolbox. I'm sure productive programmers aren't complaining. Pure FP programmers can always compile their ClojureScript to Javascript. For me, ES7 Javascript is already making me happy.

This isn't meant as a "JavaScript sucks" type of comment, but as a "being good at presenting your work is really important" type of comment. Too many really strong engineers aren't good at selling their work, so we end up with JavaScript.

<comment><USER27> I think he includes it as a joke .. clearly the first few slide states started "in 1993" and done "in 1995". The 10 days seems to be a self-deprecating joke on the popular (incorrect) meme.

<comment><USER20> No, I did original JS ("Mocha") in ten days.

The joke in those slides was how I went from my before-Netscape health (the picture of me doing a back handspring was from 1993; I joined Netscape in April 1995) to the after-those-ten-days-in-May-1995 state (looking like Ash from Evil Dead 3, with chainsaw for hand).

From 1992 to 1995 I worked for MicroUnity. No JavaScript there! It was not even a gleam in my eye, although I did write a language processor for editing MPEG-2 streams.

So I indeed created JS in a mad rush to get it into Netscape 2, along with other things Netscape tried as part of a platform play against Microsoft.

If I had not rushed, I would have missed not only Netscape 2, but also Netscape 3. Netscape 3 was supposed to be version 2.1, a minor release, until a company Netscape had acquired was given the browser and screwed up their release schedule so badly that it slipped into 1997 and became Netscape 4.

In 1998 or even 1997 it would have been too late to ship JS and have it make a de-facto standard. MS had already shipped VBScript as a me-too, and if they did not have JS to imitate, it would have been even more Microsoftian.

VBScript was the alternative to the JS rush job, in my settled view. I don't write this out of pride, joy, or defensiveness. I simply think it's the likeliest alternative outcome.

(Updated to correct Netscape 4 date per [http://en.wikipedia.org/wiki/Netscape_Communicator](http://en.wikipedia.org/wiki/Netscape_Communicator) to June 1997. It was so buggy that a series of firedrill releases were required to get it into barely usable shape by '98, which is what burned that year into my memory.)

<comment><USER30> I think that's similar to how people say JSON was discovered by Crockford. Both only use things already present in the language, but they do form something new out of them. It is sort of a middle ground between discovery and invention.

<comment><USER31> Moreover, asm.js effectively already existed, right? It's not _quite_ the same, but it's essentially a formalisation of what emscripten and the like already produced.

<comment><USER29> Is there anything written that explains this? I sort of got that impression when he talked about how JS was untyped but the js bytecode vm had types.

<comment><USER30> Modern JS VMs have type-specializing JITs. That's how they make code run fast, basically - they detect types at runtime, and emit efficient code for that.

asm.js just gives them the types, which makes things easier, but it all builds upon the existing power of JS VMs. See e.g. [http://kripken.github.io/mloc_emscripten_talk/sotu.html#/16](http://kripken.github.io/mloc_emscripten_talk/sotu.html#/16)

It just so happens that the prototype approach didn't catch on early enough. Developers are now just really set in their ways and are rather pretend that JavaScript is not a true OO language.

I feel that the addition of a 'class' concept to ES6 adds no value to the language itself, but I think it was probably a good decision anyway - <USER2> JavaScript is more flexible and adaptable than the minds of most people - <USER3> might as well use that to its advantage.

Unlike the stubborn developers who refuse to learn about prototype inheritance, JavaScript is capable of change.

<comment><USER38> Came here looking for this. Insane.

</comment></comment></comment><comment><USER39> This is a fascinating meta-post. First, it's a slideshow, so there need to be some posts about right arrows and general complaints about scrolling (as if Eich created this content himself to post to HN, instead of to be a speaker aid for himself). Second, it's about Javascript, so a bunch of people who really love lambda syntax and significant whitespace are going to show up and talk about how much better the web would be if we all ran python in the browser.

I think the web would be a lot better if we just ran lisp in the browser. Heck, I think lisp is pretty much the answer to all our problems. But nobody ever asked me.

As someone who was developing for the web in the (late) 90s, using web browsers and java as a cross-platform UI for educational software (mac and windows!) who tried to get java applets to communicate with each other (possible but difficult, and I ended up running a local java application that the applets RPCd to), I can say this with distinct clarity: the DOM and current (modern ES6) javascript system are pretty great. Sure, they could be better in some ways, but I don't trust Joe Programmer (just for example here) to understand re-entrant code well enough to write stuff that actually works in a multi-threaded environment, so single-thread event-driven is great.

People complain about this binding and so forth, but it provides a great borrowing / mixin mechanism to the language that is just flat out impossible in other languages. The prototype inheritance system is funky, but es6 classes mean you don't need to worry about it. If you want to, you can do some pretty rad metaprogramming with it, though.

Type coercion is kind of a pain, and frankly I'd love to be able to override operators (writing === semantics for objects over and over is kind of a PITA). But seriously, Javascript is pretty great. I pass around functions, chain together stuff with functional-based approaches (front-to-back no less), and can do all sorts of hip kinds of programming with it.

Maybe if we had some truly-different language driving the web, things'd be different, but don't complain about javascript and just put forward python. Put something like haskell or smalltalk on the block. Let's go big with the radical differences. I mean, c-ish languages are c-ish languages. I only wish CSS was as nice as Javascript. If I had my druthers, that's where we'd be focusing; that and namespaces within the DOM (hello, shadow DOM!)

Okay, longpost over. And late no less - serves me right for working all day instead of reading HN. Writing JS no less.

</comment><comment><USER40> JavaScript is like English. It incorporates the best parts of other languages. Starting from Java, you can now see the clear influence of Python in ES6/7 with generators and string templates. I think this is JS's greatest asset.

<comment><USER31> I wouldn't say English "incorporates the best parts of other languages", but you're on the right path. Like English, JavaScript's ubiquity has lead to it being elaborated such that it is suitable for a very wide range of use cases. Like English, JavaScript's ubiquity has made the language grow considerably, but it has made the language more flexible at the same time.

</comment></comment><comment><USER41> Interesting the Date object was a direct port from java.util.Date. It always felt a little out of place in terms of style in early javascript and this is why.

ES6 is awesome and there are so many good things happening in it. I was always a little irked that ES4 (ActionScript 3 was built on it) that had some of these elements was nixed for ES5 like typing, extending and cleaner events.

Great overview and I picked up a few things I have missed in js advancements like string handling changes (startsWith, endsWith, trim), templating with `, multiline strings!, extend, math functions, arrow, default/rest params, octal/binary literals and tons more. Many of these are probably in everyone's js libs but nice to have them standard.

I am most excited for asm.js of all due to the WebGL and gaming/app performance impact that will make when fully integrated in all browsers this year. asm.js and WebGL gaming is already giving benefit to performance in Javscript and added typed arrays to ES6.

Actually "use strict" actually makes JS an almost good language as mistakes are immediately flagged rather than "working anyway." But strict mode doesn't go nearly far enough in my opinion.

I will say for backwards compatibility you're always going to have to write "===" the only thing a flag would do is break "==" on purpose.

It does those things _poorly_ , and at great expense.

Eich did one thing, in 10 days, that was market positioned such that it became ubiquitous, and he's been banging that drum ever since -- to everyone's detriment, given how much power over technical direction he wielded at Mozilla, and how much impact Mozilla had on the web pre-Chrome.

<comment><USER8> That's not what he's actually saying there; that's a list of technical bullet points, not market adoption.

However, even if we talk about market adoption; how is Firefox OS holding up against iOS, Android, and Windows?

> _What part of that statement is incorrect?_

"Always bet on JS" from Brendan Eich really meant, for 16 years, starting in 1998 and during the time that Firefox was most influential over the future of the web: "I'm never going to bet on anything other than JS".

It's a uselessly self-fulfilling declaration when its stated by a (now former) browser vendor executive.

<comment><USER9> > That's not what he's actually saying there; that's a list of technical > bullet points, not market adoption.

The point is that if JS couldn't do these things, it would be eclipsed by a competitor. It instead grew the ability to do those things, and its competitors never gained widespread adoption.

> However, even if we talk about market adoption; how is Firefox OS holding up > against iOS, Android, and Windows?

In terms of _languages on the Web_ , JavaScript has always won. It's clear at this point that the Web isn't going anywhere, even though mobile apps are important.

<comment><USER8> > _The point is that if JS couldn 't do these things, it would be eclipsed by > a competitor. It instead grew the ability to do those things, and its > competitors never gained widespread adoption._

 _REALLY_?? JS can't do concurrency by any objective performance measure against systems providing shared state concurrency; how is a competitor going to eclipse it when the lowest-level syscall interface available to target _is_ JavaScript?

> _In terms of languages on the Web, JavaScript has always won. It 's clear at > this point that the Web isn't going anywhere, even though mobile apps are > important._

It ought to be indicative of something that the web is faltering in market segments where programming languages do more than move DOM elements around.

I would expect isNaN("LOL") to be true. Why does he put "true?!", and why does Number.isNaN("LOL") evaluate to false?

<comment><USER31> I think I can. The old isNaN() coerces to Number, and non-numeric strings become NaN in JS, e.g. +"LOL" is NaN. However, the new isNaN() just returns false if the value passed isn't of the type Number, which I guess might be useful if you're going to use isNaN() on non-Number values?

Before someone says that NaN means "not a number", technically yes it does, but it is really just a special value of the Number type.

Edit: Oh, zastavka's comment has enlightened me now. I think the reason they changed it is because now it'll check if it's NaN (return true) or anything else (return false), so it'd be like === NaN if you were able to do that. Previously it'd check if it _coerces_ to NaN. I guess the new behaviour is more intuitive.

<comment><USER58> note that isNaN() will remain as it is today, coercing to a number (and so isNaN('LOL') will continue to return true). Number.isNaN() will have the new behavior, testing for actual IEEE 754 NaN values (and so returning false for Number.isNaN('LOL')). Such is the unfortunate price of backwards compatibility.

          return ret;
        }

Parallel example:

        async function someAsync(list) {
          let promises = [];
          try {
            for (let item of list) {
              let promise = asyncFn(item)
              promises.push(promise)
            }
            return await Promise.all(promises)
          } catch(e) { /* ignore */ }
          return [];
        }

</comment><comment><USER60> For background on the user-defined operators and literals idea for ES7, see this: [http://www.slideshare.net/BrendanEich/value- objects](http://www.slideshare.net/BrendanEich/value-objects) (it took me a little while to find; it hasn't been as prominent in recent discussions as the other items). I'm excited to see all the progress Javascript is making!

</comment><comment><USER61> I wonder whether `let` should be used everywhere now making `var` effectively obsolete? Mixing both declaration styles looks bad.

<comment><USER62> As I understand it, yes, 'var' is now obsolete. 'let' does the same thing with less confusing semantics.

<comment><USER63> So, 20+ years ago, javascript was a scheme(-like langauge) -- but was disguised as java for marketing -- now we can go back to a more scheme-like javascript?

I wonder if we'd be better off with a proper scheme in the browser in the first place...

<comment><USER19> ClojureScript is pretty cool!

</comment><comment><USER65> Edit2: When do you switch off your transpiler and serve native ES6? In 2020?

Original:

What do you do in 2017? What if you already code in ES6 and transpile it to JS5 at the moment. Do you simply switch from serving JS5 to JS6?

Older browsers (todays current browser) don't support "class", "let" and other new syntax constructs. The just fail with JS errors. Can one browse the web with IE11 and iOS 8 Safari in 2017? (e.g. "lifetime support" of the device)

Polyfills can be used for pre-JS5 browsers. But can you polyfill "let" and "class" syntax keyword? One can today still browse the web with IE6 and Phoenix 0.l (early Firefox), despite a few glitches and layout bugs. Many sites use polyfills like JQuery and still use JS3 functionality made popular by Crockford "JavaScript the Good Parts". JS5 added a few things that JQuery made popular.

The syntax changes between previous JS versions were smaller in comparison to ES4 and ES6 (ES4/E4X failed and was abandoned).

Edit1: I added "What if you already code in ES6 and transpile it to JS5 at the moment." as the second sentence to make it clearer. As several down voters misunderstood my serious question.

<comment><USER58> The web is a lot more broken if you browse in IE6 than you appear to think. Some major sites work OK only because they had a financial interest (single digits of IE6 marketshare) until the last few years to maintain IE6 compatibility. This will degrade rapidly, but go off the very-well beaten path today and you'll find the web basically unusable.

Backwards compatibility on the web has long been backwards compatibility of source. Sites written in the IE6 era and not touched since should continue to work in browsers of today (which is why things like vendor-prefixed features proved to be a poor idea and are mostly no longer created). You'll get some rendering oddities, but this is still very much true.

<comment><USER65> IE11 (Win8) and various devices that won't receive an update like many Android 4 and older iOS devices will be around for a few years!

Sure, you can use a transpiler and serve JS5 the next ten years (2025). What do you plant to do? It seems most simply haven't thought about the problems lying ahead.

Many were against the ES4/E4X changes that e.g. Firefox supported for some time, as they would have broken backwards compatibility. ES6 breaks backwards compatibility with the new syntax keywords and there is no fallback afaik. If there is a fallback, well then everything would be fine.

Wouldn't it be better if such vendors would ship an security & ES6 syntax support update to their old browser software?

<comment><USER58> No, people have been against breaking compatibility with old source, like changing how certain statements are parsed and executed that would have made old code now in error. This is why strict mode is opt-in and larger ES4-like changes are dead in the water without careful design.

On the other side of things, though, new features that break in old browsers are added all the time. Try and run Date.now or Function.bind in old browsers and they'll immediately throw an error. It's only through polyfilling (and in some cases transpiling) that sites work in even IE8 today, and it will be the same situation in the future if a site wants to still work on an old Android or iOS device.

But yes, staying up to date as a user does depend on a newish browser being available for the platform you're running, and it would be great if old devices could continue to get updates. Really old iOS is out of luck, but Firefox supports back to Android 2.3, so users stuck there can download that browser to continue browsing the web.

<comment><USER67> Intuitively that makes sense until you reflect that plenty of much worse languages than JavaScript took months or years to design.

Honestly, much as it's a pastime to grumble about the flaws of whatever language we find ourselves using, I suspect if you could rerun history a hundred times, not more than ten of the reruns would give us a better outcome than JavaScript.

</comment></comment><comment><USER68> Eich states that in the original implementation of JS, Array was just Object with a length property. How did it handle order?

<comment><USER69> In JS, arrays are just objects where the indices are keys. There is a small bit of magic where any time you alter an array object, the length is changed to the largest numeric key the object has, plus 1.

</comment></comment><comment><USER70> > "Always bet on JS"

Yeah, that's why it took you so long to get basic things in the language. The JS crowd is finally excited that they have these nice shiny things. Quite a few of those have been a standard part of numerous languages for so long.

"Always bet on JS" basically means this: "JS is too big, so all the fuck ups I and others made will eventually be fixed. Because nobody is going to try to bet on anything other than JS now."

It's circular, Eich.

<comment><USER20> Joke's not funny when you explain it.

<comment><USER20> Ok, I guess I have to explain it. (Kids these days!)

I close with a slide containing bullet points rebutting all the dumb things said about how JS-can't-do-X, not to say how great JS is, but to show that software is hackable, and if Java, or Flash, or Dart can do X, so can JS. Evolving JS or doing something else is a matter of choice. JS's priority of place is not, it happened and it makes JS very hard to replace. But not hard to evolve.

I use a pic from one of Wesley Snipes's lesser movies, "Passenger 57", where the bad guy gets TOLD in a macho-funny scene on a plane, over an in-plane phone yet: "Always bet on black!" It has a great build-up with camera-work and music to match the delivery. But it doesn't mean anything more or less than always bet on Wesley kicking that pale-eyed, blond-haired villain's ass, because Wesley is a bad-ass and way more fit than Bruce Payne (who played the villain).

JS is way more fit than the comers whose fans spewed all those bogus detractions. Deal with it.

</comment><comment><USER80> I wish JavaScript "committed a teenager suicide" and we finally got a more sane language for the web. It's startling how much energy is spent to work around its bad design every day and it's not getting any better, people are just getting used to it (which is akin to voluntarily agree with having most of one's brain blown off). Even seeing Brendan showing off that he hacked the language in 10 days makes me sick to the stomach...

<comment><USER81> I struggle with a couple different tools that were developed in weeks or a couple months or on a plane ride.

Every time these guys brag about how quickly they put together the first version I just want to say to them, "yeah, we can all tell. And every day we suffer for it."

<comment><USER82> Yes. There's just no substitute for time. It's impressive to see something put together quickly, but the result is inevitably lacking in some (or more) ways.

In this talk, I couldn't decide whether his saying JS was written in ten days was a rueful admission that it's only natural for it to be a huge pile of shit, or some self-aggrandizement based on how quickly he managed to write it. I always found JS rather tasteless, so, naturally predisposed to think somewhat uncharitably of its author, I'm going to assume it's self- aggrandizement. This might be a bit rude of me, but if it's OK to rush out JS then slowly make it ever so slightly better over the next 20 years, then I think it's OK for me to form my opinions in the same manner ;)

<comment><USER20> Hume's Guillotine slices again! Please think through this keynote at a conference. I was asked to talk about the early days of JS. Why do you suppose that I am aggrandizing by describing "is" (or "was") as if "ought" can be derived in a moral sense?

JS happened, I made it in ten days because it wouldn't have happened otherwise. Had I thought it through, I might have insisted on more time -- but then: VBScript.

We don't get to call these shots. Taste and morality have little to do with their hitting targets (whether the ones we aimed at, or others). All the good stuff in JS came from giants on whose shoulders or heads I stood.

I'm not a nihilist or materialist, but I have to laugh after 20 years. JS was not planned out this far in advance!

Anyhoo, my sense of self does not depend on ten days in May 1995. My work on the Web, not just JS but especially on Mozilla, Firefox, and HTML5, doesn't need aggrandizement. My best work has yet to be seen. I'm not doing these talks to boast. Peace.

<comment><USER83> Just ignore the trolls, most of these naysayers have never implemented a new programming language in their life, but they feel entitled to talk about _taste_ and morality.

<comment><USER80> Maybe we have implemented, maybe one maybe more than one. Aren't we allowed to say what we think?</comment></comment></comment></comment></comment></comment>


Subversive-C: Abusing and Protecting Dynamic Message Dispatch [pdf] - <AUTHOR> https://www.usenix.org/system/files/conference/atc16/atc16_paper-lettner.pdf <comment><AUTHOR> Abstract

The lower layers in the modern computing infrastructure are written in languages threatened by exploitation of memory management errors. Recently deployed exploit mitigations such as control-flow integrity (CFI) can prevent traditional return-oriented programming (ROP) exploits but are much less effective against newer techniques such as Counterfeit Object-Oriented Programming (COOP) that execute a chain of C++ virtual methods. Since these methods are valid control-flow targets, COOP attacks are hard to distinguish from benign computations. Code randomization is likewise ineffective against COOP. Until now, however, COOP attacks have been limited to vulnerable C++ applications which makes it unclear whether COOP is as general and portable a threat as ROP. This paper demonstrates the first COOP-style exploit for Objective-C, the predominant programming language on Apple's OS X and iOS platforms. We also retrofit the Objective-C runtime with the first practical and efficient defense against our novel attack. Our defense is able to protect complex, real-world software such as iTunes without recompilation. Our performance experiments show that the overhead of our defense is low in practice.

</comment><comment><USER2> Since Swift uses the Objective-C runtime library, this should also work for Swift.</comment>


Please Steal My Startup Idea - <AUTHOR> http://techiferous.com/2011/06/please-steal-my-startup-idea

<comment><AUTHOR> Here's the text of my article, in case you can't get to my swamped web server:

 _The Idea_

Every restaurant menu item in the world is searchable by its ingredients.

 _Why It's a Good Idea_

It's easy to sell water to someone with their hair on fire. So I get excited about startup ideas that involve "hair on fire" problems.

Think about all of the people with strong dietary restrictions: vegans, people with peanut allergies, people eating a kosher diet, etc. These people have strong feelings about what they eat and always check the ingredients. They have a "hair on fire" problem. They would certainly use a web application that allowed them to search menu items by ingredient. There are also a lot more people who may not be so strict about what they eat but still have preferences. They would also use this web application. Probably one of the best use cases is a group of friends going out to eat, each having their own set of dietary preferences. This web application would make it easy to find a restaurant with the most options for the group as a whole.

One reason this is a great startup idea is that it adds real value to the economy. For example, I used to live in Davis Square and buy vegan cupcakes from Kickass Cupcakes and vegan muffins from Diesel Cafe. When I moved to Harvard Square, I did not know of any place to get a good vegan treat, so I would always travel to Davis Square. After about half a year, I discovered that Tealuxe in Harvard Square sold yummy vegan muffins and cookies. I would practically walk right past them on my way to Davis Square! This is what gave me the idea for this startup.

There is a genuine inefficiency in the market in that people don't buy a restaurant's menu items simply because they do not know about them. They can easily search for restaurants, but this is a sloppy heuristic for what they really want.

So I think people would definitely use this product. But users are not customers, and any business requires customers. And the rules of the game say that search engines shouldn't charge users directly, so how do you monetize?

This is another reason I think this is a great startup idea. It seems like it would be easy to monetize. For one, advertising would actually work. Whereas most advertisements are poorly targeted and buzz around users like pesky mosquitoes, a person with Coeliac disease would gladly welcome ads promoting gluten-free products. This means that ads would not detract from the positive user experience and users would actually click on the ads.

Another way to monetize is to charge restaurant owners for services. This web application would basically allow restaurants to easily publish their menu online to an eager audience. You would be driving business to the restaurants, so it's easy to add enough value to restaurant owners that they would be willing to pay for your services.

Finally, there is room to grow more products and offerings. For example, users could review and comment on individual dishes. They could also get alerts when new menu items appear in their neighborhood.

 _How to Pull It Off_

Web applications like this face a chicken-and-egg problem: without any data, who would use your service? That's why I think the best way to execute on an idea like this is to start with a very small, local niche. For example, you could start the product off as a way for vegans in Cambridge, Massachusetts to search for vegan dishes. Starting small makes the first step much less daunting. As you gain traction, you can expand geographically and broaden the dietary preferences.

It's also not hard to think of companies who may be interested in acquisition, so exit shouldn't be hard.

However, there is a big challenge in assembling accurate data about menu items, which can be especially tricky with potentially life-and-death issues like allergies. So this idea still presents some interesting challenges.

 _Why I'm Giving My Idea Away_

When I came up with this idea I didn't think I had the right business skills and domain knowledge to execute it well so I set it aside and moved on. But this idea really stuck with me and is one of my favorite startup ideas so I hate to see it end up in my dead pool. I think the world would be a better place with this product so somebody please steal this idea!

<comment><USER3> No ideas original, I guess.

I'm working on something very similar (although it's part of a larger product) with a a couple of co-founders.

Hoping to launch this October.

<comment><AUTHOR> Fabulous! I would actually be very surprised if no one else had already thought of this idea. I think it's all about executing well, because an opportunity certainly exists. I wish you all the best!

<comment><USER4> I have to say I have a similar idea with this and how to execute it too but I haven't started on this as I'm doing something else to start off with.

The restaurants giving out menu ingredients is quite idealistic though but possible using GroupOn-mentality (eg Everyone's doing it so I should too).

<comment><USER5> Having worked in the restaurant business for several years, this will certainly be a key problem.

I work at a fine dining establishment right now for extra money, and I can tell you no matter how many other restaurants were doing it, our head chefs would be unwilling to share ingredients.

<comment><USER6> What about just major allergens? Peanuts, soy, wheat, etc, etc? Information that would be given to anyone dining at the restaurant if they asked.

<comment><USER5> yes, they have no problem with giving out that info

</comment></comment></comment></comment></comment></comment></comment><comment><USER7> It depends but I can say that for allergies, it isn't so sure it would be helpful.

First, with severe allergies, you very rarely go to the restaurant at all. Second, just checking the ingredients is not enough, you have to worry about cross contamination, or the origin of certain ingredients or the oil used to cook them. Sometimes, they seasonings, sauces or other preparation from an outside supplier whose content is not always known. Going after the suppliers often lead to yet more suppliers to check.

It may prove very useful for people with food intolerances, vegan or even diabetic people if you add glycemic information for the dishes.

<comment><USER8> Not only that, but any service that is relied upon to say whether some dish has nuts in it or not could get themselves wrapped up in a phat liability case in the odd case that it causes a problem.

<comment><USER9> Liability issues are the first thing I thought of when I read this idea.

With the small market of dietary-limited and the complete exposure this puts on the restaurant (open to both litigation and copycats), why would any restaurant go for this?

</comment></comment></comment><comment><USER10> A Google search for "kosher restaurants" suggests the kosher SEO winners are not very aggressive.

Result 1 (<http://www.shamash.org/kosher/>) requires that you know the name of the restaurant ahead of time.

Result 2 ([http://www.greatrestaurantsmag.com/KOSHER/restaurant_az.php?...](http://www.greatrestaurantsmag.com/KOSHER/restaurant_az.php?restneighborhood=IL+%28Chicago%29&restcuisinelist=&restcheck=&byrest=&byletter=)) is not bad. It lets you search by city, but the design is pretty old and cluttered.

Result 3 (<http://www.nachas.org/BethYehuda/kosher.html>) is just a static html list/table of kosher restaurants in NYC. Could be a good source to scrape for seed data.

A search for "kosher" in the Android Market lead me to the <http://KosherNear.me> app, and its web-based equivalent <http://locatekosher.com>. This seems to be the most modern offering.

</comment><comment><USER11> "The Idea: Every restaurant menu item in the world is searchable by its ingredients."

I'd settle for accomplishing the first, most basic, step. As Rick Emerson said on Twitter a week or two ago _"Would someone please tell all the god damn restaurants out there to stop only putting their menus online in PDF format?!"_

<comment><USER12> A good portion of restaurants in my area don't have any sort of menu online. As far as I'm concerned, a restaurant's website doesn't need to be anything but a menu.

</comment></comment><comment><USER13> We created something like it a few years ago: <http://biggestmenu.com/>

Flan: <http://biggestmenu.com/?q=flan>

Pizza: <http://biggestmenu.com/?q=pizza>

Coffee cake: <http://biggestmenu.com/?q=coffee+cake>

</comment><comment><USER14> Would there not be issues in which restaurants don't want to reveal all the ingredients in their food? I can imagine some places would want to keep `secret` recipes from competitors.

Assume that is a non-issue, I think that a mobile app would also be a good source of revenue. If you have a food allergy you could find which dishes are `safe` without having to consult the waiter (who may not know). I could see people spending $5 for an app that did this.

<comment><AUTHOR> Cool, I didn't think about mobile monetization.

Perhaps it's a better idea for restaurants to list what ingredients are _not_ in the menu item, since most people are trying to avoid ingredients instead of seek them out. That would solve the secret recipe problem.

<comment><USER14> Though it looks like there is at least one app that does this already: <http://allergyfreepassport.com/mobile-apps/>

</comment></comment></comment><comment><USER15> When I did the slow carb diet earlier this year, all I wanted my phone to tell me was where I could get some meat, nuts or veggies.

Starting with one local niche (like vegan) sounds like a good idea, but I'm not sure if there is one food niche in particular where the users are both unfamiliar with the current restaurant offerings, and also would be passionate enough to build a habit of the app.

Being the company who indexes the long-tail of all restaurant niches for consumers might be the better way to service user need. I've worked in this area before, and menu entry is kind of a solved problem through vendor incentive, mechanical turk and outsourcing - but you definitely have to be clever about it.

In any case, aspects of this idea are serviced by several businesses - <USER2> services, mobile startups, food delivery, deals, etc. However, what I see missing from this particular proposal a no brainer value proposition for the restaurants - I believe this is a requisite for scale.

<comment><AUTHOR> "what I see missing from this particular proposal a no brainer value proposition for the restaurants - I believe this is a requisite for scale"

Yes, I think this is a critical part of the business model. Once the product has critical mass it's much easier to offer an attractive value proposition to businesses, because you've engaged this large mass of potential customers. Before that, though, it's trickier.

</comment></comment><comment><USER16> I posted this on the blog too, but keep an eye on my startup, <http://forkly.com>

We just might solve your problem ;)

<comment><USER17> good luck with your beta lunch!

</comment></comment><comment><USER18> While I love the big thinking behind the idea, as someone who tried to launch a similar, restaurant related, Web startup, there are at least two major issues:

1) High restaurant turnover - Approximately 60% of restaurants either close or change owners within the first three years of existence ([http://www.whitehutchinson.com/blog/2011/02/the-truth- about-...](http://www.whitehutchinson.com/blog/2011/02/the-truth-about- restaurant-failure-rates/)). This can make it incredibly frustrating to try to build lasting business relationships.

2) Scalability - If the growth of the startup is limited to how fast you can build relationships with restaurants (see above for problems), it will be a long slog and likely an unappealing investment.

Having said that, I too look forward to someone making this happen. I've already got my scars from attempting it, so I hope someone better than I takes a crack at it. I just tend to think it will be an OpenTable, Yelp, or Eats.com who finally solves the problem (although biggestmenu.com looks pretty sweet).

</comment><comment><USER19> Great idea. I don't eat or drink things that contain gelatin. It makes me dizzy. If i was able to check whether a product has gelatin or not from smartphone app, without bothering to read through all the ingredients that would be great.

Moreover, i don't eat meat. This makes my life in "Here" extremely difficult. I would be very very happy to find local restaurants which serve food without meat.

</comment><comment><USER20> This is an awesome idea! However, it's for a very specific type of entrepreneur: The non-vc backed lone-gun or family business. Or a small group that is 100% committed to building a moderately sized profitable company for the long haul without funding. My gut says it has the potential to grow to low 8 figure revenue per year in 5 to 10 years.

The online restaurant space is not as lucrative as many other sectors because restaurants tend not to spend much money advertising online. So it fails the classic VC test of "Is it huge and getting bigger". You'll probably have a hard time raising money for this biz, but if you can go it alone, it could be a great long-term play.

Friends have started companies in the restaurant space and one of my siblings is a chef.

</comment><comment><USER21> My startup's infrastructure (still in development, could use funding ;) ) would be perfect for executing, in a comprehensive way, your idea. I've spent a couple years refining the back end and just starting into a development centric front end.

</comment><comment><USER16> So, interesting question...what's better? Tagged as "contains gluten" or "gluten-free"?

<comment><USER3> I think "gluten free".

For the record, my startup to be, looks to be tackling the same "problem" as you are with Forkly (great name btw). That is, personalized food and drink recommendations.

Although based on what little I've seen of your product, we might be taking two different approaches to it.

Best of luck to ya!

</comment></comment><comment><USER22> I think this idea definitely has some legs, but unless you incorporate it somehow with a pre-existing social networking framework or product, it's not really something that can turn into a fully defined product I think.

</comment><comment><USER23> I'm 42 years old and have yet to meet a vegetarian or anyone who suffers from a real "food allergy" (meaning someone who would get actually sick by eating something that most other people find edible).

Therefore this idea seems very "American" to me -- which doesn't make it bad, just local. Fish not knowing they're in water, etc.

Of course some people have preferences, but if you're just looking after some kind of food vs. another, the name of the dish, or the name of the restaurant, will tell you enough...?

<comment><USER24> I'm Australian, and a friend of mine gets very sick when exposed to carrot, mint or nuts. It's not just an "American" thing.

(I'm just lactose intolerant, which means I just want to avoid food that is going to make me feel a bit unwell. Nothing critical, but it'd be nice to know if the restaurant's chef is dumping butter into something, or if the "Fetta" is actually cow's milk.)

<comment><USER23> I'm not saying food allergies don't exist; I'm not even saying they don't exist where I live (Paris).

But I am saying that where I live they're uncommon enough that nobody ever talks about it.

My daughter is going to school next year for the first time; on the form (which I filled this morning) the question is in fact asked: does your child suffer from food allergies?

But while the rest of the form is typed, this question has been added _by hand_ at the very end of the form...

<comment><USER4> I know a guy suffers from red meat allergy. It's not that it would kill him, but it causes a reaction in headaches, soreness, tiredness, etc.

The joking expression goes "How do you know if one of your customers is a vegetarian? They'll let you know."

</comment></comment></comment></comment><comment><USER25> I'm probably going to get downvoted for this, but in honesty, I can't see this idea working, the problem for me is lack of coverage, and lack of users too - it's a standard chicken-egg thing ... Also, you can search menus by ingredients they have, but searching by ingredients they don't have could prove problematic ...

I think I just prefer the hands-on, word of mouth approach in general ...

</comment><comment><USER27> I am working on something like this. www.dietmanager.com. I also tied it in w/ the usda food database web service to break things down even further and tied in a feedback loop so that people know what ingredients trigger their conditions etc...

<comment><AUTHOR> Wow! Don't be shy about promoting this in the comments of my blog, if you'd like.

I'm curious, if you don't mind sharing, how does it know what restaurants to recommend to you?

<comment><USER27> There are 3 meal delivery methods

1\. Local Chefs

To get this info local chefs can upload their menu's. Their food items are run against the USDA food database then categorized against which dits allow those things and which do not. I currently have support for 455 diets

2\. Restaurants

Some of this menu info from the restaurants uploading their menu's and some comes from info that I can get from online sources; as with the local chef menu's I use the USDA food database here to know what meals qualify for what diets

3\. Recipes

This one I have not quite figured out yet.

My app does not work like others in that it does not recommend "Places" it instead allows you to search for what food you want and it finds meals based on that food item that also match your dietary preferences (which may or may not be a pre-defined diet)

</comment></comment></comment><comment><USER28> This is a problem where technology is actually a very huge obstacle, probably a huger one than marketing. How are you gonna get all that data? It's not structured on the web so you can't easily crawl it. You have to rely on people uploading it to you, but why would they do that when you don't have a huge user-base yet? Think about the friction a restaurant has to overcome: they have to hire someone to create XML files (don't expect regular owners to know how to do this)... then they have to regularly update it...

Ask HN: Rate my project: MakeYourGirlfriendHappy.com - <AUTHOR> http://www.makeyourgirlfriendhappy.com

<comment><AUTHOR> Hi HN

This idea came about after my own experience (as PG would suggest). Basically it is a weekly newsletter with great tips (one coming Thursday) + a Reminder system for her birthday, anniversary and valentine's day. Very keen to get your comments.

Two for free deal, let me know what you think.

Cheers,

Jonathan

<comment><AUTHOR> Same tips, so you can signup too! We will eventually grab that domain name too (take right now).

</comment></comment><comment><USER3> Hmmm... This domain name seems to be rooted in a mindset that the man has to be the one to "do stuff" to keep the girlfriend happy.... eg, that she's the prize, and if you don't supplicate to her as she demands, she will no longer favor you with her graces. I'm not sure perpetuating that mindset is a good idea.

How about "BeAHappyCoupleTogether.com" (or something) where there's no overt bias towards suggesting who is the more important member of the relationship?

Really, there's just as much onus on her to make you happy, as vice versa.</comment>
