chengmi··on SearchYC Presents: Best of Hacker News
If I understand the problem correctly, doesn't this list (http://searchyc.com/top/submitter) confirm that? Our data on users' karma is somewhat limited. Turns out that the sum of your points across submissions and comments does not equal karma (downmods have more weight).
chengmi··on SearchYC Presents: Best of Hacker News
We gave that some consideration, but the queries weren't all that interesting. The vast majority of those lists (something like 80%) consist of people with only one post. To illustrate this, here are the top tens for those queries:

  Top Points per Submission
  +-------------+------+----+---------+
  | username    | pts  | ct | avg     |
  +-------------+------+----+---------+
  | dwaters     |   95 |  1 | 95.0000 |

Point taken.
chengmi··on Obama's Victory Speech
I've been hacking since last night, and I found this interesting. My point is, news doesn't have to be about technology, business, or startups to be interesting to hackers.

Blasphemy.
chengmi··on "A significant amount of skill with a soldering iron and some custom firmware has revealed.... Kindle"
I just found it odd that the title heralded his "skill with a soldering iron" when the real work was done in software.
chengmi··on "A significant amount of skill with a soldering iron and some custom firmware has revealed.... Kindle"
From his blog: "I wasn't able to solder cable to the connector without shorting (the pins are 0.5mm apart!), so in the end I removed most of the pins, soldered short wires to the removed pins and inserted those I needed back into the connector."

You most certainly can solder wires to a connector with 0.5mm pitch without shorting anything. It takes a magnifying glass, a good soldering iron, and a very steady hand. Interesting article, though!

chengmi··on Something new for the New Year: SearchYC.com
No, would you like to? You can search a user's submissions AND comments, though: http://searchyc.com/danw+submissions+or+comments

Fixed--you can turn off JavaScript now, if you want.
chengmi··on Something new for the New Year: SearchYC.com
I hope you guys find this website useful. I know there are a bunch of other YC searches out there, but we're trying to improve on all of them.

1. nycs.bigheadlabs.com - a good one created by the Disqus guys, but they stopped updating the index quite awhile ago, so all of the search results are stale.

2. trk7.com/yc - Another YC search, but the interface is really confusing.

3. ycsearch.com, Google - Indexes insanely fast and has an excellent relevancy algorithm, but you can't sort by post date or points.

4. Firefox toolbars, etc - I haven't tried them, but I assume it just uses a Google custom search.

5. SearchYC.com - full text searching, 15 minute updates, and a cool user-search feature (try searching for your username (case-sensitive)). We also enable sorting results/submissions/comments by relevancy (sucks), YC points, or post date.

What we really want to do is to start generating some user stats and interesting queries such as "top points per submission", "most linked-to websites", etc. If you're interested in one, post it here!

Anyways, we want you guys (YC users) to help us decide where this goes. The sky's the limit!

Happy New Year's!

chengmi··on Suggested YC News CSS patch
I have the same issue. It's bug in Firefox Mac. AFAIK there's no fix for it until FF3. You can still mouseover and scroll, but there's no scrollbar.
chengmi··on Ask YC: Deciding what programming language
Yes.
chengmi··on Startup Math: 1 + 1 = 1/2

 // Sorry, couldn't resist...
 
 #include <iostream>
 using namespace std;
 
 class Integer {
   public:
     int value;
     Integer(int rhs) {
       value = rhs;
     }
     int operator +(Integer rhs) {
       return value + rhs.value;
     }
     int operator /(Integer rhs) {
       return value * rhs.value;
     }
 };
 
 int main(void) {
   Integer one = 1, two = 2;
   cout << ((one+one) == (one/two)) << endl;
   return 0;
 }
 
 // Output:
 // 1

chengmi··on My laptop was stolen.
1) A car is for transportation, not storage. 2) Laptops, like children, should never be left unattended. 3) No one needs insurance until they need it. 4) Finish your code, make money, and buy a new laptop.

chengmi··on Do Not Stand While Presenting To VCs
The article isn't saying that all standing presentations are bad, just ones with VC. With that said, I think that people should present however they're most comfortable.
chengmi··on Next Gen Wind Power Generator - Popular Mechanics 2007 Breakthrough Award winner
1. This method wouldn't work in heavy traffic. 2. That "nearly constant 10mph breeze" is improving fuel efficiency for the cars behind you through reduced wind resistance. 3. A similar idea for generating power from traffic is through the use of speed bumps as power generators. But that doesn't work either. Here's an interesting article from wired: http://www.wired.com/science/discoveries/news/2001/06/44518
