secret··on [dead]
Thanks, idiot.
secret··on R in production systems
The advice to go 64-bit and throw RAM at the problem brings back memories of my computational math class.
secret··on Poll: What is your gender?
I realize you say this jokingly, but seeing that at this there are almost as many others as female (14 v 16) I'm curious how they define it. If I had to guess it would be mostly male->female given the overwhelming number of males, but I have no idea.
secret··on Show HN: Publ.ca - Instant and Beautiful Web Publishing
Here's some quick thoughts: if this is going to be used for short stories (fiction/non-fiction, but not blog posts) you could monetize by letting readers build an anthology and printing nice volumes for them. You could also (if the authors agree) license the content to other sources.
secret··on Ask HN: Should the Internet be included in the constitution?
Ah, I get where you're coming from now. Interesting to think how that would work.
secret··on Ask HN: Should the Internet be included in the constitution?
The Second Amendment isn't really about self-defense:

A well regulated Militia being necessary to the security of a free State, the right of the people to keep and bear arms shall not be infringed.

secret··on Canadians Just Became World's Biggest Internet Losers.
My old boss was born and raised in France and would use that expression all the time. She thought it was funny.
secret··on One with Vim
I kind of agree. I prefer the middle ground of notepad++ (with plugins for code completion and ftp/file explorer). Light and powerful while still resembling something designed for human consumption.
secret··on Ask HN: What would you like to search and can't?
Math related search is generally not good. You can find theorems and definitions but proofs (non-famous ones) exercises are difficult to find.
secret··on I launched 06-10 and constantly feel helpless and lost. What advice do you have?
Have you tried getting mentioned on travel blogs? Try looking specifically at the ones targeting backpackers.
secret··on We're not based in the valley.
Florida either, but the humidity is even worse!
secret··on Ends Don't Justify Means (Among Humans)
There's a difference between sacrificing another and sacrificing yourself.
secret··on Ask HN: What new things are you planning to do this year?
I don't see why not. I learned the math part of that (and more) in one year of grad school and basic C++ instead of the two languages. Just takes dedication if you're doing it on your own, I know I couldn't have.
secret··on Ask HN: 20+ Postings in 20 minutes of HN. Is this considered spam ?
I agree there should be a cost for posting stories, even going so far as preventing further submissions if you fall below a certain threshold. You could raise your karma back up through commenting.
secret··on Begging for Your Pay
I've always interpreted that phrase to mean "they're not doing this for free, you know" because of the tone in which it's usually said.
secret··on Why I Switched to Duck Duck Go Permanently
To add on to this, every search engine is generally pretty bad at math related searches. It may be something worth looking into.
secret··on WikiLeaks Archive — Cables Uncloak U.S. Diplomacy
While I don't think it's the case, I do think it would be a brilliant strategy. The NYT article on the Iran negotiations seems rather helpful to the US, but nothing that could ever be said officially (especially the positions of other nations).
secret··on Google Voice for iPhone Released
It definitely takes longer for calls to connect and I think it may drop calls more frequently when using it on a cell (although it has improved greatly in that regard from about a year ago). I recently started using it through gmail and have been told the calls sound much better. Not sure what it all means.
secret··on Google Voice for iPhone Released
There is no voice lag in GV that I've noticed, I think it works more like call-forwarding than voip.
secret··on Ask HN: What are you reading right now?
Walden by Henry David Thoreau. It's public domain, so you can get it free. I challenge anyone here to read the first page and not immediately want to read the whole thing.
secret··on Benoit Mandelbrot, RIP
Sorry about the weird formatting, it looks fine when I paste in the comment box. You'll need to add line breaks after the comments to get it working.
secret··on Benoit Mandelbrot, RIP
In his honor, here is Matlab code to generate a Mandlebrot set (from an old homework assignment):

function inValues= mndl(limits) %no inputs needed, used by the script to zoom in

%amount of detail to calculate; larger number = better resolution, slower calculation stepsR=300; stepsI=300;

%maximum iterations used in calculations maxIter=50;

if exist('limits')~=1; %intial range of real and imaginary numbers to compute lowerR=-2; lowerI=-1.25; higherR=1; higherI=1.25; else numel(limits)==4; %range to compute after zooming in, determined by axis lowerR=limits(1); lowerI=limits(3); higherR=limits(2); higherI=limits(4); end

%Constants: slR=(higherR-lowerR)/(stepsR-1); slI=(higherI-lowerI)/(stepsI-1);

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Create the Mandelbrot image.

[x,y]=meshgrid([0:stepsR-1]slR+lowerR,[0:stepsI-1]slI+lowerI); inValues=ones(size(x)); z=zeros(size(x)); c=(x+1iy);

h_z=1:(stepsRstepsI); for counter=1:maxIter z(h_z)=z(h_z).^2+c(h_z); h_z= h_z(abs(z(h_z))<2); inValues(h_z)=inValues(h_z)+1; end %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%format presentation of Mandelbrot image colormap jet; pcolor(x,y,log(double(inValues))); title('Mandelbrot Image: Zoom In and Sharpen for Details'); shading interp; axis off;

zoom %turn on zoom feature initially clear inValues

%Buttons:

%recalculate image to enhance after zooming in (just calls the function %again with new input argument based on current axis) h1= uicontrol('Parent',gcf,'Units','points', ... 'Callback',['mndl(axis);zoom;'], ... 'Position',[105 5 105 20],'Style','pushbutton','String','Sharpen (after zooming in)');

%turn the zoom button on or off h2= uicontrol('Parent',gcf,'Units','points', ... 'Callback',['zoom'], ... 'Position',[215 5 55 20],'Style','pushbutton','String','Zoom On/Off');

%reset the image h3= uicontrol('Parent',gcf,'Units','points', ... 'Callback',['mndl();zoom;'], ... 'Position',[275 5 40 20],'Style','pushbutton','String','Reset');

Haven't advertised yet, but if you go to http://minvp.com/apps you'll find everything I send out in the email.
secret··on "I modeled this website on the same principles of Walmart"
OK, I felt compelled to check some of the source. Aside from references to tripod.com and every js library out there, here's what I saw where there were credits:

secret··on Ask HN: Review my startup, ActiveInbox (GTD Gmail plugin w/ $20k donations)
Not to continue the off-topic, but I've noticed this problem and started a mailing list just focusing on review requests (http://minvp.com). Of course, that too dropped off the new page with no comments :)
secret··on Show HN: Review our public website?
I'm not adverse to creative spellings, but it just looked like a typo as opposed to being intentional (which I realized after seeing it in a few places). Just my gut reaction.

Overall it seems cool. I just got an iPad myself and think there is a ton of growth in store for tablet apps.

secret··on Show HN: Review our public website?
- The first question I would have is about pricing. What's the point of a free trial (for you and your users) if they won't pay afterward?

- I would change the generic iPad home screen to one showing your app.

- Also, I was going to comment on how you had a typo, but I see that the product is name MnuBox. Not sure how I feel about that.

- I second what SHOwnsYou says, especially about creating a product tour.

secret··on Southwest's acquisition of AirTran: Why they're doing it and why you should care
While not good, that is part of hedging. It's basically an insurance premium for a policy they never had to collect on.
secret··on Ask HN: How can we pivot our startup?
That's a good point on #3. Just to toss out an idea- what if the service offered tracking of the referral and could provide some sort of analytics to help retailers optimize their social campaigns.

For example- I complete a purchase on Retailer A and I am presented with your widget and: maybe I get a rebate on my purchase, or a coupon for next time if I share on Facebook, or maybe the rebate goes into effect if a referral completes a transaction. You could use something like bit.ly to track the links. Ultimately, one of my friends sees this on his feed and goes to Retailer A and makes a purchase.

The retailer would be: 1. incentivizing the user to share and 2. be able to see some sort of stats analyzing which campaign is preforming better.

I think I would definitely be tempted to pay for something like that.

secret··on Ask HN: How can we pivot our startup?
Some quick thoughts:

1. I went to the demo page and even though I read the instructions, it still took me longer than it should have to notice the FB stuff. Without instructions and specifically looking for it, I would have never noticed it was there. I guess placement can vary by store design, but the demo would leave me with that worry.

2. From the merchants perspective, I could see the benefits of having users talk about my products on Facebook, but I don't know if distracting a shopper when they are closer to making a decision is worth the trade off. In other words, is the expected value of the links worth the diminished likelihood of purchase? I can't see this increasing the possibility of a sale to the current user. I could be completely wrong and in that case, any data/statistics you could provide merchants would go a long way to convincing them to use Zuupy.

3. To combine 1 & 2 and suggest a potential pivot: As a guy, I am highly unlikely to ever talk about or seek out advice for a general run of the mill purchase. I may seek out the help of, for example, a photographer friend if I'm going to buy a camera, but that may be the extent of it. Maybe I'm just more introverted than others, but going by my FB feed, I've haven't seen it happen much. Judging by the background graphic on you widget, you seem to agree that the target users are women. From my highly unscientific observations of my wife and her friends, they like to show off purchases they are proud of (say they discovered some new fashion and got it at a huge sale). So, what if instead of allowing users to chat with friends before making a purchase and possibly deterring it from occurring, users are presented with a big widget right after the purchase to share and discuss with their friends. You still get the free links plus a stronger social endorsement (this person has just made a purchase) and you don't ruin the conversion funnel. If I was a merchant, I could definitely see myself signing up for something like that (bonus points if it just plugged in to existing shopping carts).
