Circles are not always invisible. A circle made up by a closed-loop line source of photons would be visible. (They're kind of hard to make, though.)

It's sort of the question of what is the smallest thing a human can "see". Stars, for example, are extremely small, far below the resolution of the human eye (outside of the atmosphere, of course). Yet seeing them is not a problem, you just get an unresolved image.
Hi Mike,

Thanks for your time and generosity! I just entered the beta phase for my side-project OtherMind, a fast way to take notes and make lists (http://othermind.me). I'd really appreciate it if you could try it out and let me know whether you think it's useful and marketable. Any feedback in general would also be great.

Thank you so much!
It works fine on SPARC too; you just have to know where the data is coming from.

You're right to point out that people should be cautious about this code. I'm just listing my "favorite tricks". I'm not recommending that people use integer casts as their go-to string comparison.
Hmm, vertical line was planned to be just a node, from out of which events in time grow out. That being said, there's no difference between left and right.
I suppose you're right. I have sitcom thoughts. That would explain a lot.

birth rates in all modern western countries are declining, in a few to the point where reproduction is not guaranteed (eg. fewer than two children per couple). I believe this trend will likely continue to the point where we don't reproduce and instead (hopefully) cease to die.

Do you have a piece of code you feel confident about, such that you'd be able to say "here is an existence proof of carefully-written resilient C code of some significant length"? I'd like to take you up on an offer to validate that proof.
What is real estate wholesaling?
The term wholesaling usually applies to manufactured goods selling. As a furniture wholesaler, you would buy some couches from a supplier and sell them to a customer, for a profit of course. This analogy perfectly translates to the real estate market.

a vague and decidedly unintelligent jumble of neural networks and genetic algorithms.

Not at all true. More like an unintelligible jumble of Bayesian learning, Markov fields, structured regression, support vector machines, and other statistical models over large volumes of data.
Those are great points. I completely agree.
Mike:

This is great, and helps us confirm and prioritize areas we'd like to improve. Would you mind if I emailed you with a few updates we're working on?
Indeed; it's strange they bury it that deeply. Thanks for rooting that out.
You should definitely call it Overmind! (From Starcraft, it's the zerg master; or zerg brain if you will)

1) Technicaly, there are 2 possible locations that the same distance from each of 3 satilites, but the other point is far off in space. The 4th is vary useful for increased accruacy when you have a shitty ground clock, but it's not 'needed' it's it's loss simply results in lower accracy which can be compensated for by more readings over time. (Which can be vary useful when want accuracy and have a ground station that only get's to see a small chunk of the sky.)

2) They all have polar orbits that reach the same location 4 minutes earlyer each day. However, there horizontal ground speed relative to a stationary observer changes over the course of their orbit. (It's zero at the pole and maxes out at the equator.) And is also diffrent form the other satilites you are comparing it with.

Which is why you get those S shaped paths:
http://www.n2yo.com/satellites/?c=20

3)I agree but see 2.

PS: Yea, that picture was fairly bad, I was looking for an easy to read article not a picture. The classic picture of a constilation with fixed polar obits is vary misleading once you take the earth's rotation into consideration. It's rare to find something that shows both the orbit's and their horisontal velocity fairly accuratly without making it look like they interweave. I once saw an animation showing the orbit of 4 satilites and the area they could cover area just those 4 satilites could give you coverage of but it's far harder with just a picture.

You need to have the right balance of being hungry, which can be solved my having enough money in the bank for a year or so.

If you have too much money or are too comfortable, you'll never get your app finished, because there will always be other things you need to do (I've been there many times). If you are freaking out about making rent, you won't be able to concentrate either.
stay tuned; I've gotten a sneak peak of the product, and you'll be blown away by how useful and simple it is. When I showed it to mobile app dev friends(who've tried to build this themselves), they all said that they needed this yesterday.

As a user, it would be nice to know exactly how the score is calculated. I can see what part comes from which site, but for instance, my github profile only contributed 2 points to my WFP profile. Is this because I only have 2 repo's? Or because my repository isn't watched/forked? Or is it based on updates, etc?

I really enjoy the site, however. If I could add one feature, it would probably be a short landing page that I could edit to maybe include a short description and maybe a link to a blog/resume.
>>> Just think how much fun it will be when I say, “Send a text to Andrea that says ‘I love you,’” and Siri hears, “Send a text to Andrew that says ‘I love you.’” I look forward to seeing how reliable it really is.

If some threshold of certainty isn't met, Siri will certainly ask "Did you mean Andrew or Andrea". Doesn't seem like a really hard problem.
Wow, that's crazy amazing. I've really enjoyed some of the WebGL stuff I've seen, I only wish there was a more natural way to control the camera angle...The click and Drag thing drives me nuts.
It doesn't sound like they negotiated an exclusive license to the technology in the initial contract. If that's what they want, they should pay for it. Assuming the value of your work is now proven, I think you should work that angle. "You see how valuable this is; wouldn't you like to have exclusive rights to it?" The price should go up by at least 10x.
I don't think the writer was criticizing neural nets and genetic algorithms as an approach, just observing that what they have produced so far is "decidedly unintelligent".

I would use this...especially if you can get some talented teachers interested in it. Good UX and interaction features will be key to convince people to move past Youtube.

Also, the idea reminds me a bit of guitarmasterclass, but that is more a repository of videos than a back-and-forth learning place.
I disagree. While we could figure out how to travel to the moon in a very short time (think 60 years from the wright brothers till neil armstrong), anything beyond mars might well be far beyond our capabilities. this is much due to the fact that any chemical reaction based propulsion is so inefficient, that travelling beyond mars would be extremly costly and consume a large part of our earthly resources. If we would promote nuclear reaction based propulsion devices I might get hope again - but those are politically difficult to promote (because of very reasonable concerns about their dangers).

nonetheless I'm pretty optimistic about the possibilities of genetic reengineering. a lot of that research is really constrained by those ancient (aristotelean) laws concerning stem cell research.
People should care a lot less about downvotes, and, votes in general. I bump up comments that were clearly downvoted to express disagreement. That's the fix to this problem, not trying to convince 1000 casual users to change the way they use the downvote button.
Thanks for the feedback. I agree on the screenshot, just not entirely sure what to do with that space (I'm a programmer with very little design skills, but I'll try to remove it and works something out)!
Someone posted on the original article that "You cannot recall smells..." That is one possibility. Pandarus could give Manelaus a bottle of a very specific perfume that Pandarus was familiar with. If Pandarus smelled the perfume in the future, he would know it was Manelaus. But if captured, he would not be able to remember the perfume's smell -- at least not in a specific enough way to reproduce it.
I'd just like to point out that Minecraft's code is absolutely horrible from an algorithmic standpoint. On performance/speed and code quality metrics, Minecraft is a statistical fluke.

I think the sales page isn't bad. But it feels bland.

- Your value add is probably not the elegant interface you're showing us. Sure, eye-candy is great, but the features you outline below talk about "Anywhere Monitoring" and "Multi-Server Listening Support", etc. Maybe an image of a guy staring at his phone (anywhere) with lines going from his phone to your logo to his servers. Give people an "at-a-glance" of how your product works.

- I'd draw more attention to your "Call to action". It let's me know immediately what you want me to do. Should I view the demo? Should I give you my cash? Maybe you want me to look at features? (You probably want my cash above all else. Why not show it?)

- (This is super nit-picky, but...) Your copy reads in blocks. (Imagine Ben Stein doing a voice over for your website.) There's no visual rhythm on the page. Spend a few hours looking at other sales pages (Here's a good spot: http://startupli.st/startups) and look for patterns (ignoring, of course, all the cookie-cutter landing pages).

-- The important parts of description text LEAP off the page at you.

-- Very focused call-to-action.

-- Strong images which relate their message.

+ This is a great start! You have the important parts of the page down. Now you just have to tweak it. (Even the best do this: http://37signals.com/svn/posts/3007-37signalscom-homepage-ev...)

Do you think there's still a market for feed readers? I've built one (not public yet) with two somewhat distinct features: 1. you get a river of news with the ability to perform complex search queries against your feeds; and 2. it provides relevance sorting of articles based on your reading history.
I've found that search, when accompanied by tagging, provides a reasonable alternative to the folder-based feed management approach while relevance sorting helps cut down the time I have to spend wading through the never-ending stream of articles.
Should I consider opening it for the public? I don't want to spend money on hosting and bandwidth unless there's a reasonable chance to recover some of the associated costs.
I particularly enjoy showing people the little known "goes to" operator:

-->

with example code such as this:

#include <stdio.h>
int main()
{
int x = 10;
while( x --> 0 ) // read "while x goes to zero"
{
printf("%d ", x);
}
}

The above code compiles and runs, listing the numbers from 9 to 0.

For more details on this little known operator, I recommend this stack overflow question:

Given his comment it's a good bet he's running Linux. There is no Silverlight for Linux so his complaint is pretty legitimate .
The string literal is (all but -- honestly I'm not sure what the standard says here) guaranteed to be aligned naturally for the platform. The thing on the left hand side is not. If it's a pointer to a heap block, you're fine. If it's a pointer to a token parsed out of string input, it can be anything.

Even architectures that support misaligned accesses can be configured to trap on them and generate unexpected fatal signals.
I didn't mean to imply I didn't profile (otherwise I wouldn't know what parts to write in C). I've been doing profiling (and trying various non-C ideas on what may help first). I'll have to look into PyPy and Cython, thanks.

Yours was the comment I was going to make. Furthermore, while I appreciate Yegge's thinking, I don't see how the facts he presented are not common knowledge already. We easily can observe Google's lack of "platform"; whether or not this is an issue for the company is open for debate. It is not as if Steve revealed some super-secret metrics which reflect negatively on the company.

Can Microsoft Salvage Windows Phone?
It would be hard to make Crysis in 8-bit assembly, but it's not especially hard to make an NES game in 8-bit assembly. In many ways, it is much easier than modern game development:

- There is no hardware abstraction layer. There is one hardware target, you know exactly how it works, and you can use/abuse it any way you like. And all the hardware is designed together for the sole purpose of making games.

- There is no I/O. All your code and data is just mapped into memory from a ROM pack. You have to swap memory banks in and out, but you can layout the banks explicitly. You typically do one level per bank and just swap banks to change levels.

- There is no memory management. RAM is all yours. You just layout your dynamic data explicitly, or let the assembler do it, or some combination of the two.

- There are no data types or undefined language behavior. Just n-bit registers and instructions. Need to use 12.4 fixed point math? Or pack a flag in the high bit of a pointer? No problem, just write some assembler macros.

Of course, in exchange for control, you have to give up some power. Maximum 16k of code, can only write to video memory between rescans, no divide instruction.. that kind of thing. But better the devil you know. It's a lot more fun solving "how can I do this with what I have?" than "what the hell is going on?"
Steve Jobs and the Seven Rules of Success
I quit my salaried day job with the intent of going into startups or consulting. I planned to take a week off, then seriously start looking for contracts, and if I didn't find anything I'd start looking for a more regular job after a month or two.

I was contacted the week I updated my LinkedIn profile to list myself as freelancing. An old friend had a husband who needed help with a big contract he had, and we ended up splitting the work fairly evenly, making good money, and creating a good site for a very large client.

I was surprised how easy it was to find contracts. In fact, I haven't had to go hunting for them yet.

I'll admit, I've been making less now than I did with my salary, but that's in a big part due to working on a startup on the side.

I'm afraid I can't provide a definitive definition, I'm not even sure if there are one that everybody would readily agree upon. But what I had in mind was an understanding of intentions or meaning from context rather than having to explicitly be told what to do.
Thank you for your solid reply. I think ANN is the real thing, and most of the other "AI" solutions that we have give the impression of intelligence, but are simply algorithms that solve problems we have in very well defined ways.

ANN is a general intelligence that gets shaped by experience and adapts figure out its own solutions. This is the path that will lead to our concept of AI presented in sci-fi and what the general public actually thinks of. It isn't some coder banging on the keyboard trying to replicate what a human would do under a specific situation, it is something that truly learns.

We have a long way to go before this becomes a reality, but it will happen.
This is my kind of app; I really like it. Particularly how you can do everything from the big textbox and how can send stuff by sms.

Things I'd make better:
- Provide a rest API; I'd love to be able to use it from my console
- [Tab] would be really useful (To complete tags or date)
- When I click "out" of the textbox when editing a todo, I don't want the [cancel] [save].. just save it.
- I've tried to twitter it but it said something went wrong; It might be twitter or me though.. but still worth telling you
- I'd like a quick keyboard shortcut a-la workflowy. I.e. If I have multiple tags and I want to remove one of them can I do -#tags? Or something similar.

I could suggest lot of other things that "could be nice but would make it more complicated"; but instead, I'll use it for a while and stay you informed on what I really find missing.

Also, little bug:

When you add your account info (Email, phone), there's a textbox on the main page but we see html tags in it.. i.e. a href=mailto instead of a link.

Keep the good work :)
They also are a leader (especially in terms of revenue) in servers. They are strong competitors in gaming, controlling 2 of the major platforms (Windows and xbox). They are the leader in office productivity software (This last one might not fit with the others as well, because it office is not as much of a platform as the others).
But like I said, it depends on what the code is. If it's a kernel module, then you'd be silly not to use the gcc extension. Likewise if it's a platform-locked linux or mac thing (Android middleware, maybe). You work in security, where you're expected to port stuff between platforms regularly. Not everyone does. And those extensions are there because someone likes them.

1) The intersection of three spheres results in two possible points. One of which is most likely somewhere in space or deep below ground. So 3 satellites are actually enough in theory. Altough you get a [much] higher precision with more satellites.

hello mike.. :D

i be quick, i made a powerful media player inside the browser(html5/js) the response is average (for now). i would like to know what do you think about the idea. i understand idea is not everything and execution matters but it would really help if the base idea is strong.. app in question: goo.gl/kS86a

i would like to know what should i focus on, user experience (fixing small bugs, polishing along as i develop) or development (adding big features), add support for more platforms (web, windows 8, pokki, etc), or try to raise capital, try for YC or startup-Chile for example (i don't really need capital, but i could really use everything else that things like YC do for startups [most importantly they would allow me to work full time which i can't do currently because of college])

My opinion after messing about with the developer preview is that the Metro UI is usesless with a mouse driven setup. I found many things frustrating, as in there was no way I could find to "kill" the piano app in the preview. I had to ctrl alt del to kill it, there was no "X" or "close" or virtual "home" button to press that I saw. Granted, I was running this via virtual box, so its possible that there are some quirks that way. I just dont see a use for a "touch" style ui with a mouse. I have a magic trackpad that I would have loved to try, but I havent installed the boot camp drivers yet.
In those days it took about a year, maybe a year and a half.

Many teams would carry a core "operating system" (really a library of system routines/process scheduler/IO/audits) from game to game and build off of that. That left more time to write the game mechanics and choreography.
Indeed! On the disturbing side, eventually computers will be capable of this sort of thing. If you thought face recognition was scary, imagine if computers could identify you by your walking habits. Imagine how that plays out once you factor in the growing omnipresence of cameras and the longevity of digital data.
