You should post some info about your product. When you're pitching to top-notch developers, you're basically "applying" to them, not the other way around.
davidcann··on Rate our startup: Challenge.gov
I just heard a story about this on the PBS NewsHour podcast. It's a nice overview of the project!

davidcann··on Google.com has an animated logo using an HTML/JavaScript particle simulator
Sure, that's a consideration for smaller brands, but I don't think google has any trouble with consistent brand recognition.
davidcann··on How HTML5 Will Save Podcasting and Make it a Billion-Dollar Market
If I understand correctly, you're suggesting that users will verbally speak to the iPod while the podcast is playing. Wouldn't the most common spoken command be "skip ad"?

The concept of interactive audio programming is interesting, but it doesn't seem likely to become commonplace.

davidcann··on Kevin Rose steps down as CEO of Digg
Can someone please un-editorialize the title?

The CEO transition has been planned for months. It may be poorly timed, but the title of this link makes it sound like he's resigning due to the v4 launch issues.

davidcann··on SublimeVideo HTML5 player released as a service
It's really unfortunate that this pretty player will be only as a service - with a monthly fee.

I'm not willing to trust them with hosting the player and/or videos. This also seems to severely limit customization.

davidcann··on GazeHawk (YC S10) Does Eyetracking With Web Cams
Is there an example page where we can test the accuracy of the eye tracking software?

I like the idea, but for $490, I'd like some assurance that the eye tracking technology actually works and that it's not just tracking the mouse or something else.

davidcann··on Six Months Later: Seven Major Websites that Send Passwords Unprotected
I went further still and stored the key on a disk that was on no network at all!

That's a good solution and it sounds like your system was about as secure as one could expect when needing to store sensitive data in a reversible format.

davidcann··on Six Months Later: Seven Major Websites that Send Passwords Unprotected
Storing passwords in plaintext (or obfuscated) in a database is not what the author is saying. He's simply saying that they're not using encrypted HTTPS connections, so if a user logs into one of the offending sites over a publicly accessible connection (i.e. public wifi), anyone nearby could use a sniffer app to see their password travel over the network.

Regarding the Super User post, he's correct that storing passwords as reversible rather than plain text is a LITTLE different, but if their servers are compromised, the hacker could simply run the reverse function on your password to retrieve it. The one situation where it's safer is if the database tables are hacked, but the server's code is still secure.

I'd argue that storing reversible passwords is almost the same as plain text, but I'm interested to hear if people think reversible is significantly better than plain text.

davidcann··on A Case Study of “Designed By Developers:” Stack Overflow
Am I the only one who thinks good application developers should also be decent designers? Why does everyone assuming that a person must fit into only one group?

Being a good developer is not about typing code, it's about creating a great application. That means using all of the tools at your disposal... code, visual design, workflow structure, analytics, etc.

In my experience, traditional designers often do very poor work when it comes to interactive applications. As a developer, it's my responsibility to tell them it's crap, why, and present a better solution.

davidcann··on Sify.com Architecture - A portal at 3900 requests/second
The 3900 requests per second are likely not constant. That number is probably during their busiest time during the day, so their infrastructure needs to support that kind of traffic. You're right, though, requests per second likely includes all file types.
davidcann··on Ask HN: How much does it cost to outsource iPhone app development?
Sincere contrats to those of you who are consistently getting this rate.
davidcann··on New iPhone Dev Agreement Bans the Use of Third-Party Analytics and Services
It sounds like someone should create a self-hosted iPhone analytics software package. Perhaps one of the existing companies will release their software as open source.
davidcann··on Ask HN: How much does it cost to outsource iPhone app development?
Everyone reading this, please don't think the ~150 an hour range is normal for an individual developer. This is generally the rate for a full service design/development agency where you get an account manager, secretaries, etc.

I do iPhone development and haven't met anyone getting even close to $150/hr individually. If someone made that, they'd be be making $6,000/week and $300,000/year.

yish, can you confirm that this is an agency rate, not an individual developer/designer rate? or is this the rate you're making personally?

davidcann··on Ask HN: New project, pick.im, A Freelancer Marketplace
Two more issues I noticed:

* The keywords I enter on my profile keep getting re-ordered automatically by your software. It wants to put javascript first, but that's not my primary language, so I don't want it appearing first below my name. I've opted to delete it from the list instead.

* I'd suggest that the "time to complete" and "cost for similar" fields in the Add Project form to be optional. I prefer to not have this kind of information posted publicly, so I had to enter dummy values.

davidcann··on Ask HN: New project, pick.im, A Freelancer Marketplace
I like it, but I'd suggest an option for searching "anywhere" or at least by country. I freelance full time, but rarely work with companies near my physical location.
davidcann··on Xachi Pets fuse iPhones and Stuffed Animals into one Cute and Cuddly iToy
This is my startup I'm doing with a few friends! We presented at the Open Angel Forum last week, so we're currently raising an angel round of funding to bring it to market.

We'd really like some advice from YC and HN people with experience pitching hardware startups to investors.

davidcann··on NFL Games Have 11 Minutes of Action
iTunes does this and the games are actually captivating to watch in 15-20 minutes of the best plays. Don't look away or you'll miss something. They also use the audio from the radio commentators, which is usually a lot better than the tv commentators.
davidcann··on Mockingbird: New tool for building mockups, written in Cappuccino
Awesome, nice job!
davidcann··on Ask HN: What is the going rate for developing an iPhone app?
Ok, I think this is a big point of confusion. A "company" rate is very different than a developer rate. A company rate usually includes project managers, client liaisons, secretaries, etc. I can't imagine an individual developer getting paid $20,000 for one month of 40-hour-per-week iPhone work.

I think it's important that we make this clear to new developers, so thanks for clearing it up.

davidcann··on Ask HN: What is the going rate for developing an iPhone app?
So you're honestly making $250,000 (40x125x50) a year doing contract iPhone apps?

Edit: I just saw you posted below about $40/hour. That's fine to overestimate when you're charging $40/hour. My comment is directed at Rothmic and malbiniak above. Apologies for the mistake, drewcrawford.

davidcann··on Ask HN: What is the going rate for developing an iPhone app?
Congrats if you truly get that rate for every hour you work on multi-month projects.

I'm currently making apps for Disney and I price total projects based on a detailed spec (not hourly), but when you figure actual hours worked, I don't charge anywhere close to this rate.

Do you really not stay up until 4 am polishing the app even when you're over budget?

davidcann··on Review My App: Zen
Some full size screenshots would be good to have on the Tour page rather than the current lengthy text descriptions. After skimming through the whole tour, I still don't have a sense of whether or not your app is better than Basecamp.
davidcann··on Ask HN: Please review my new project: almost.at
Definitely a bug... thanks for the report.
davidcann··on Ask HN: Please review my new project: almost.at
Thanks for the report. That looks awful! I'm going to try to reproduce it.
davidcann··on Ask HN: Please review my new project: almost.at
Events are suggested by users (the little + button in the lower left). Currently, I approve/reject them by hand to keep it focused. Eventually, I'll have a public voting system.
davidcann··on Ask HN: Please review my new project: almost.at
Not really, but there's not much "personalized" data on almost.at to save. If there were (or is in the future), then yea, your data could definitely be saved and displayed when you return. Check out 280 Slides from the creators of Cappuccino: http://280slides.com
davidcann··on Ask HN: Please review my new project: almost.at
Yea :/ I've been trying to solve that bug, though it has been elusive, thus far.
davidcann··on Ask HN: Please review my new project: almost.at
Hm... that's not good. It should have a sidebar on the left. Looks like it's Chrome on Windows, right? I'll have a look and see if I can reproduce it.
davidcann··on Ask HN: Please review my new project: almost.at
Yea, though technically it's not "compiled" ... only the browser wrapper is compiled objective-c code. It's still just html/javascript running inside.
