Ask HN: What are you working on?

I got the first paying customer for Appointment Reminder the first day it was open for business. (DB id #22, after a bunch of test accounts and friends & family demos.) ~2.5 years and ~$1,000 later he still happily pays $29 a month. This was not unknowable prior to launching the site (though I was still on pins and needles): I had already walked the sales pitch for it to enough businesses in downtown Chicago that I was pretty sure some number would buy what I was selling if it were put in front of them.

I think people who are pre-business vastly overestimate the difficulty of getting the first sale and probably vastly underestimate the difficulty of reaching scale. Gail Goodman has a presentation on the Long SaaS Ramp of Death. When you say those words in a group of SaaS entrepreneurs you'll see pained recognition on everybody's faces, even those (of us?) whose businesses are fairly successful. Dear God does figuring out the scalable marketing piece take time. (I've got it figured out for Bingo Card Creator, but have only isolated bits and pieces of the orchestra playing in disjointed fashion for Appointment Reminder.)

I kind of feel like I beat on these drums to death, but organic SEO, AdWords, lifecycle emails, and an optimized first-run experience are sort of my favorite arrows in the quiver for increasing sales. That and a whole lot of just grinding it out.

Also, tie a string around your finger for Rob Walling's presentation from Microconf 2013 where he takes HitTail, a SaaS he acquired, from ~X to ~30X in recurring revenue over the course of a year. (There are numbers in the presentation but I remember him asking us to be circumspect about them.) He goes into month by month detail of what he was doing, and you'll understand the level of sheer frustration involved until hard work and ingenuity starts to reveal "flywheels" (his word for scalable/repeatable acquisition channels). As far as I know, this isn't on the Internet yet, but I expect it will be late this year.
> I didn't say the New Yorker is hyperliberal. I said that the idea that solitary confinement is torture is hyperliberal

Your exact words were, "only a tiny minority of hyperliberals would consider to be true". Since I had linked to the New Yorker which explores the issue in depth and gives significant credence to the idea, your aspersion quite apparently included the New Yorker. To say that it didn't is either revisionist, or you weren't clear with what you originally wrote. The New Yorker is a mainstream liberal publication.

> That's absolutely irrelevant to Constitutionality.

Agreed, but you also ignored the question about cruelty. I brought up those other points to make it clear that I'm not hyperliberal, not even necessarily liberal. I think it's good for our economy if ex-cons are able to work.

I believe the New Yorker and J. Law & Policy articles make a strong case for cruelty.
When high tariffs on the importation of sugar prevents countries from developing their own agriculture industries, it's not just a first world problem. It's BS like this that causes international tension, wars, and famine. This situation isn't as superficial as it may seem on the surface.
It's a mistake to respond by saying that he must not understand the theory.

And I'm not saying he must misunderstand the theory. I'm saying it's a mistake IF "he thinks 'get out of the building' means 'go out and find an idea for a startup'" which is what TFA seems to be saying on at least some level. But I'll allow that I may have interpreted it differently than what the author intended.

Still, when you read this:

I cold emailed the guy to get a meeting to chat about his business. I was hoping I’d discover a problem I could create a new product around.

If you’ve read any of the dozens of books about running a Lean Startup (I’ve read them all), you’d probably call this “getting out of the building”.

... it sure seems to be saying that "get out of the building" directly corresponds to "go out and look for a problem to solve" as opposed to "go out and validate an existing idea".

But there could be some hyperbole in there that I missed on my first read, and it's entirely possible that I took that part too literally.

Edit: I should also say - the author of TFA is showing a transition over time, in his approach, and his learning based on experience (as you note). It might be more accurate for me to say that he may have misunderstood the theory previously, rather than to say that he currently misunderstands it. Certainly I largely agree with the position he takes nearer the end of the article, which is somewhat different than where he started.

I think the big open question, for which there is no easy answer, is something like "how far do you go based solely on scratching your own itch before you do go out and look for external validation"?
Final Plea.

I too liked Computer Shopper for both the ads and the articles. All of the BASIC Stamp articles were quite the thorough treatise on the capabilities of that small system.

But what I miss is the openness. I've got the databook from Western Digital that let me write a BIOS for CP/M for the Cromemco series machines, it told me everything I needed to know to exercise every feature of their chip. Today, due to a combination of licensing and just sheer complexity issues such data sheets have largely faded away. I've been playing around with some of the ST Micro ARM chips and to really "get" them you have to have the ST Micro Data sheet, the ARM Cortex-Mx TRM, and the ARM7-M TRM. That is a ton of information about a chip with millions of transistors. Its just hard to put all of that into an accessible space. Even the lowly Microchip PIC or ATmega parts have fairly large datasheets associated with them compared to say the Z80 data sheet.

The most annoying though are the interconnects. You could easily get all the bus specs for the original IBM PC, but getting all the USB specs for a modern one? Harder and harder.

I really dislike the pervasive sense that I, as a developer, need to pay some tribute to the manufacturer before they will "allow" me to develop things with their product. Its not a general case thing, Atmel is pretty good about telling you anything you want to know for example, but every time I run into it, it leaves a very bad taste in my mouth.

Translating this forum is hard. They uses a specific language that has tons of reference to the way Iranian government sees the world. For example they never say "Israel", they would say instead "Usurper Regime". Because they never recognize Israel as a country.

What we have here is a forum by Iranian semi-military force "Basij". They bluff all the time and you never know what is truth. They have no shame in photoshoping and manipulating the truth.
The 'crush' scenario presented here -- governments using their fiat currency power to alternately buy and dump Bitcoins, creating a boom-bust cycle that scares other people away -- doesn't seem very smart or likely to succeed.

Speculators would recognize it and attempt to profit by front-running the government operations (increasing the cost to the government, and dampening the volatility).

Bitcoin service providers could offer volatility-protection (instant conversion to other currencies), as some do already.

Governments could lose money on each manipulated boom-bust cycle, and at the bottom of each cycle, Bitcoin would still be alive and ready for new uses.

Far more likely, in my mind, is an attempt to coopt Bitcoin. Officially approve it, with reporting/identity conditions that don't encumber legal use but ensure tax collection. Or, launch a Bitcoin-like competitor backed by government redemption guarantees (T-Bills, TIPS, etc). So, above-ground businesses can get most of the crypto-currency benefits without the rough edges created by its most anti-State qualities.

Long copy often converts better, actually. Personally, I liked the page. I prefer it when I can find out what the service does and how before I have to sign up.

Also, consider that if, like many other pages, this one just had a few soundbites and a big "Sign Up" button, the conversion rate to signups may be higher, however the conversion rate to paying customers is another matter altogether.
> This sentence in the introduction assumes a level of choice on the part of the mammals that is pervasive in the article but never substantiated or even formalized to the point of a testable hypothesis.

The field here is evolutionary biology, and specifically the area of parental investment and applications of game theory. It is very common in that area to talk about "choice" etc. while not meaning anything conscious. For example, it is acceptable to say that genes "want" to propagate copies of themselves, but of course this is just shorthand for something very different. In the field, this is not misunderstood, it is the norm.

> The study found that gender bias in birth rates can affect the number of grandchildren.

No, the point was that they found that gender bias in birth rates appeared to be not entirely random (50-50) and weighted towards what generates an optimal number of grandchildren. That exactly supports a hypothesis that has been around for decades that through female choice (again, choice is not meant in the sense that I can choose what to eat for lunch), animals can affect gender birth ratios in order to maximize the number of grandchildren. (Here you can see the connection to game theory.)

It is very hard to study that empirically, which is why this study is receiving a lot of attention - after decades, it is among the first to actually give measurements.

> nor do I accept their statement that the study taking place in a zoo means that their findings are somehow more likely to be present in the wild. That would require a different experiment on its own.

This is indeed a weakness in their methodology, and surely being debated heavily.
"Ethnic" is not a synomym of "non-white."
There is also XRay Editor (http://mireus.com/xrayeditor/) that comes with an Xcode plugin to relatively easily convert the changes you made into code. It also has an overlay feature to be able to adapt to a mockup.

Then there's http://hierarchydetective.com/ which is OSS, still pretty rough. It support a few different hierarchies like UIKit, CALayer, cocos2d and can supposedly be easily expanded for more view hierarchy types.

Spark Inspector and Reveal are pretty similar at the moment. SI does notification tracking and also live UI updates (and rotating the 3D view in the client by device movement ;) ).

You weren't the only one they confused. John Timmer at Ars Technica did an excellent writeup[1] about the study and the somewhat questionable aspects of their conclusions.

I would quote the relevant bits, but it's basically the entire article pointing out possible (and unaddressed) issues with the study:

"Although some of the results are suggestive, given the somewhat confusing and, in some cases, contradictory nature of the result, it would seem to be appropriate to interpret them with caution, and go back and start a larger population of rats on a study with a more consistent design. The authors haven't gone that route..."

Go has a trick where you can set a channel to nil in order to get its functionality ignored in your select. If you gave the select all the possible channels and turned them on and off rather than adding/removing channels you can obtain similar functionality.

Humans are functionally better than (current) computers at GO[1]. The reasons for this are your answer (and I might be talking about 'GO' type Games, rather than merely the Game of Stones).

And, being honest: you've no chance of cracking even weak AI before you understand the homo sapiens consciousness a little better[2]. It's more powerful than you think (by a fairly large magnitude, with no hesitation to say this. A large margin.): 'autistic savants' are often used as a measure of this[3], but they're actually not so interesting. There's a lot more NP problems in that noggin of yours, and a lot more potential.

He actually has a point, sadly.

It's not enough to get you a visit from the feds or anything, but it's almost certain that any competent intelligence agency is storing anything that touches that website. Whoever posted it likely has links in their social graph to very high value targets.

However, in certain cases
the players may adapt their strategy depending on a
piece of advice. The latter is delivered to all players
by an advisor. This opens the possibility for the
players to adopt correlated strategies, which can
outperform independent strategies. There are various
forms that advice can take. For example in the case of
correlated classical advice, the advice is represented
by a classical variable, l, with prior r(l). Each player
can then choose a strategy depending on his type and
on l.

...

For Bayesian games, the possibility of having access to nonlocal correlations, for instance using entanglement, has important implications. First let us
imagine that the players can share quantum advice,
that is, the advisor is able to produce entangled particles and to send them to the players, who then perform local measurements on their particles. Since the
statistics of such measurements can in general not be
reproduced by any classical local model, the players
now have access to strategies which would be impossible in the case of a classical advisor. Thus, players
sharing quantum advice can outperform any classical
players.

So, if some players have information that other players don't, they can outperform the others? Astonishing :-|

You should look a bit more closely at what I said :)

Iranian "Parastoo" On Hacking Spree, Govt & Corporate Targeted, Drones Hijacked
Then know that it was your interesting idea, since I wasn't thinking of anything automatic myself :) Maybe is possible to automate things like generating code that minimizes branching, or re-uses objects instead of destroying and allocating them all the time... but it's definitely possible, in some cases at least, to rethink the approach and reduce GC. Especially since there are usually trade-offs (using a fixed amount of memory "just in case" is distasteful for its own reasons), and the programmer might need to make an informed decision.

But people still need to be aware of it first; making new objects for one time use is handy, and the normal way to go about things. It's certainly the default way tutorials tell you to get the time (even in game loops). At least personally, before today I didn't even know about Date.now(), and I never saw a discussion about any of this stuff in regards to libraries (how good or sloppy they are with GC)... it just doesn't seem to be on the radar, outside of gamedev. And by the time stuff gets sluggish by the accumulated little objects here and there, there is no easy fix, other than a whole lot refactoring or rewriting from scratch with it in mind.
Yes you need to know all the channels ahead of time, this restriction simply doesn't exist in core.async.

The US does use drones over its own territory, but whether it's for "legitimate reasons" is still a controversial matter. One planned use for them, if not already, is to patrol the US-Mexican border.
