jkupferman··on Schwab password policies and two factor authentication
Fidelity had a similarly terrible password policy (6-12 characters, only letters and numbers). I complaining to their tech six months ago and got a stock "we're looking into it" answer. In the past month they've actually fixed the issue and now require 6 characters (upper case, lower case, number and symbol).

jkupferman··on Ask HN: Alternatives to Evernote?
After getting frustrated with Evernote being slow and buggy I switched to Simplenote (http://simplenote.com/).

It's simple, fast and seamless. You start typing and it automatically syncs your note for you. It does one thing that does it well. That being said it doesn't have all the bells and whistles that Evernote does (audio notes, OCR, etc).

jkupferman··on Ask HN: How do you drive web traffic to your successful side projects?
I haven't done any load testing on this app in particular since it's pretty low volume. However on another high-traffic Rails app I did some benchmarking and found Unicorn to have a 10% faster response time and much less variance at the high end. Obviously YMMV.

Funny enough I build an app that is almost identical: http://memeifier.com/

jkupferman··on Show HN: Mixtrss - the best mixes (20+ min) on Soundcloud
yeah, the data is refreshed (and re-sorted) daily. You will often find the same mixes for a few days since they keep getting more popular, but good new mixes will bubble up while older ones fade away.
jkupferman··on Show HN: Mixtrss - the best mixes (20+ min) on Soundcloud
Creator here. I'd be happy to hear any thoughts or feedback you have on mixtrss. I've been using it for the past few months and thought you guys might enjoy it.
jkupferman··on Ask HN: Do you listen to music while coding? What genre makes you more creative?
I generally enjoy longer, continuous pieces of music so that my mood can flow with the music and I don't have to spend time tinkering with playlists.

I started by listening to prog-rock (Pink Floyd, King Crimson), then moved onto sample-based stuff like Dj Shadow and RJD2. Now I mostly listen to EDM/Mashup dj mixes from soundcloud which are great. I've been enjoying them so much I built a small site for finding the best mixes (http://mixtrss.com/).

jkupferman··on Ask HN: Caching pages with login form/"Hi, Bob" components
37Signals described how they tackled this problem in Basecamp Next (see the "Thou shall share a cache between people" section) http://37signals.com/svn/posts/3112-how-basecamp-next-got-to...

Their solution is similar to #4.

To your concern about disabled javascript, you can still do what they describe but add CSS classes to all elements that would need to be hidden for non-admin/logged in users and just use display:none;

Finally, I would given some serious thought to who the audience is for the application. For most applications the % of users for whom javascript is disabled is so tiny for the amount of work it would require that it is not worth the effort.

jkupferman··on WanderStyle: Hipmunk for Fashion
Just some observations:

-I can't seem to find any benefits that this provides beyond at traditional Comparison Shopping Engine (e.g. Google Shopping). Why would I want to use this over the existing ones?

-After clicking through on a product I ended up on a product which was out-of-stock ( http://www.bluefly.com/just-a-cheap-shirt-cyan-and-brown-pla... )

-While I have the heading and subheading font installed (Raleway) it is isn't very readable, at least on Windows.

-Most searches I put in had 200 pages of results, some way to most effectively view results would be awesome (infinite scroll, filtering)

-The link to click-through was often slower than I would have liked, this can add a big drag on the shopping experience

The idea of a higher end comparison shopping engine specifically for apparel is a good one. The question is how can you improve the overall shopping experience to make it compelling for your users.

jkupferman··on Conversation between Steve Jobs and Developers at WWDC 1997
At 5:55 his "saying no to customers" mantra sounded eerily similar to 37signals http://gettingreal.37signals.com/ch05_Start_With_No.php
