heyjonboy··on Henry Kissinger Has Died
It’s a Howard Zinn quote. Or a System of a Down lyric, depending on where you’re starting from.
heyjonboy··on The Cart Narc and His Camera
> doesn't give two craps whether they're grabbing carts from the parking lot or stocking shelves

Having worked exactly this job at the local mall in high school, I can assure you that grabbing carts was preferred to stocking shelves.

heyjonboy··on More Americans are using fake license plates
Many of the subjects of Streetsblog's "criminal mischief" (defaced or obscured plates) are vehicles displaying NYPD parking permits. This problem won't get solved until someone besides the police is tasked with fixing it, at least in NYC.
heyjonboy··on NYC jail complex to be restored into citywide green energy hub
OP expressed a concern about prison capacity, and I think the intent in referencing the 90s crime rate was to point out that Rikers has seen much higher crime rates that what we're currently seeing.

How would you build this?

heyjonboy··on Handcuffed to Uber
No, that's incorrect (speaking as a founder who's raised $35mm and sold shares on the private market). Private financings will trigger a new 409a valuation but won't influence it. 409A valuations are typically based on Black Scholes and have no connection to private funding valuations. Secondary sales only affect fair market if there's a functioning secondary market, and AFAIK there are no private startups with a FUNCTIONING secondary market.
heyjonboy··on Handcuffed to Uber
This article is wrong. Option strike prices and taxation are based on the 409A "fair market" valuation, not private valuations achieved during fundraising. Move the decimal one place to the left and the numbers in the article get a bit more realistic.

tl;dr: Science journals have lately be charging fees disproportionate to their perceived value.

Another project that does this - https://github.com/jonthornton/MtaSanitizer. Free and self-hosted.
heyjonboy··on Inside the Dark, Lucrative World of Consumer Debt Collection
The real story here is how little effort most healthcare providers put into debt collection.
heyjonboy··on Send money to debit cards
Those airline miles are paid for with the processing fees charged to merchants by credit card companies.
heyjonboy··on Common Python Mistakes
Does this link crash anyone else's Safari on iPhone 5s?
heyjonboy··on From beginning to end, the story of a failed parking startup
Yup.
heyjonboy··on Google Ventures Puts $258M Into Uber, Its Largest Deal Ever
> Isn't the whole point of "going public" to raise money?

It used to be. Regulations introduced in the past decade have made it very expensive to be a public company - there's a lot of accounting and legal overhead. These days it's easier to raise large sums of money privately and only IPO when those investors want to cash out.

heyjonboy··on Jon Stewart: Lower entrepreneurial risk
Startups don't forgo health insurance because it's expensive, they forgo it because purchasing health insurance is a gigantic, time-consuming pain in the ass.

Ha, I saw that one and immediately thought Iron Maiden: http://images.wikia.com/logopedia/images/6/69/Iron_maiden_lo...
heyjonboy··on AirBnb's new site design
It's a new homepage, not a new site. The profile pages are unchanged.

heyjonboy··on LESS.app For Mac OS X
From the FAQ:

I'm on Windows. What do you recommend I use to work with Less/Sass/CoffeeScript, etc?

A Mac.

heyjonboy··on Timepicker for jQuery inspired by Google Calendar
Yup, the time inputs just need a common parent element for the datepair example, and it doesn't have to be the direct parent. You could use a table or do something with floats.
heyjonboy··on Timepicker for jQuery inspired by Google Calendar
Very true, mobile wasn't really taken into consideration with this plugin.

One option would be to use a <select> dropdown as the element you attach $.timepicker() to, and only initialize the timepicker for certain screen sizes. Other screens would see the default <select> element, which works better on mobile devices.

heyjonboy··on Preventing form re-submission with HTTP 303 redirects
"Note: Many pre-HTTP/1.1 user agents do not understand the 303 status."

The fact is there really aren't any pre-HTTP/1.1 browsers still in use. See: http://serverfault.com/questions/110932/are-there-internet-u...

Given that many web apps these days require javascript and CSS and HTTP/1.1 is over 12 years old, I don't think it's realistic to worry about clients that only support HTTP/1.0.

While 302 works in practice, it's safer to use 303, which works by definition.

heyjonboy··on Preventing form re-submission with HTTP 303 redirects
I've noticed older versions of Firefox trying to resubmit form data when refreshing after a 302 redirect.

Granted there aren't many people running old versions of Firefox, but why risk it? Even if 302 is generally interpreted like a 303, it's safer to just use a 303.

heyjonboy··on Preventing form re-submission with HTTP 303 redirects
Ha, hadn't thought of it that way, but I can see what you mean. I added it to play around with Canvas, while tying in with the half-tone dot motif in the header.

It could definitely stand to be a bit more subtle, though.

heyjonboy··on Show HN: This weird bug is probably present in your Nginx configuration.
Another method is to automatically serve certain file extensions as static:

  location ~* ^.+.(jpg|jpeg|gif|css|png|js|zip|ico|xml|pdf|html)$ {
  	access_log        off;
  	expires           30d;
  	break;
  }
heyjonboy··on Ask HN: Chicago-Area Startups
http://www.parkwhiz.com - We started in 2006, when it seemed like TechCocktail was the only startup community in town. Ended up bootstrapping the company, and we recently opened an office in Roscoe Village.
heyjonboy··on Motorcycle instincts and start-ups
Interesting analogy. The gist seems to be that for both startups and motorcycles, momentum is more important than it is for cars and large companies.

Any idea if there's a correlation between motorcycle ownership and startups? I happen to be a member of both groups (Suzuki SV650 and ParkWhiz).
