The problem is that the early rich, tend to spend the same way as the ultra rich, in order to fit in.

Why? Conditioning. Anywhere you look, you see lavish lifestyles being advertised. And after you hit a few mil, you start thinking "hey I'm rich, I should spend that money, like those rich guys spend".

Just because you hit a jackpot, doesn't mean you need to spend 10% of your newly found wealth, buying a Ferrari

Ask HN: Compressing sets of rectangles... help me find an algorithm?
I'm looking for a fast way to do the following: given a set of rectangles in the plane, return a minimal set of rectangles that covers exactly the same space.

By "minimal" I mean "having the fewest number of rectangles". However, it's more important that the algorithm be fast, so it's ok to approximate the smallest set if that would speed things up.

A variation, if that's too easy, is to introduce color: given a set of colored rectangles, return a minimal set of rectangles that covers exactly the same space, with the restriction that no rectangle can include regions that have different colors.

This feels like the kind of thing there must be standard work on (image compression?), so I've probably been searching in the wrong places. Do any of you guys have ideas about the problem and/or pointers about where to find relevant work? Thanks!
True that is the case with many, but in some cases online games like http://www.minecraft.net/ are solely supported by the fans, users of the game as it is being built.
The name sounds like it's a site for liberals...or an operating system for left-handed people. Or a cereal. Or something. It doesn't sound like a name for what it is.
Google Voice Gives Out Free Business Cards, Makes Switching #s Less Irritating
Stewart Brand gave a TED talk recently ( http://www.ted.com/talks/stewart_brand_proclaims_4_environme... ) in which he said that people moving into urban areas have less children, and much of the world was moving into urban areas these days.

Hopefully the population will start to decline due to lower birth rates... I hope at least. :)
Not that google owns the 'wave' label, but with more than a few months of knowing Google is making a run for a big 'wave', wouldn't you have thought adobe would have gone for a new name (though they obviously would have already had the wave name before google was public with it).

Simple site for me to learn Rails. Took the "solve a problem" idea to "which of these two [X] look better?" (for outfits, haircuts...whatever). Get a crowd to vote to get more opinions. The initial people are uploading some unexpected things though.

100 Years of Design Manifestos
Nice gesture, but as of earlier today the server with the card creation software was so slow as to be unusable.
Yes, there's more than one. On Ubuntu, for instance, just look at how many JVMs there are to choose from in the package manager.
ZBrush is a great iteration story. The first versions were for "painting with depth" and when they realized the value in their tools for painting on models, they developed, iteration by iteration, modeling, sculpting, texturing, etc. The legacy of that iteration can be painful in points (dropping tool to canvas is only one such example :-)

As for the math: yeah, tell me about it. I do a lot of 3D game work. I've become quite comfortable with transforms, most quaternion stuff, and boat loads of vector math. However, it took me many, many years to get it down! And I don't really enjoy it that much. I find it tedious and frustrating when all I really want to do is work on the game play logic. That's why I'm not volunteering to disrupt this particular industry...

Do you like Pet Sitting? Get listed for free in Petgigs.com
If you are a pet sitter you need to get your name out there. People don’t simply hire anyone to take care of their pets. Many take just as much care finding a pet sitter as they do a baby sitter. People love their pets and often think of them as members of their family. So, if you are a pet sitter it would be advisable to get some online visibility with good reviews and feedback.Gone are those days when people found needed services in the yellow pages. The trend now is to look for services online.
The issue was not exclusion, nor bashing. The code has been accepted by a driver maintainer, and there were surprisingly few critical undertone mails on lkml, however legitimate (namely, adherence to the Linux coding conventions).

What is not pointless is honesty, and not even Linus[1] can say, that the code drop was honest. Microsoft should have said: somebody found us in violation of the license we think is important [the licensing legalese itself, not the GPL], and this is how we fixed it. Sorry for our mistake, we do our best. This is not what happened: instead it was sold as an act of benevolence. Voleurs.

You cannot blame people for hating dishonest legal persons.

[1] should take a long look in the mirror and ask themselves why they are being so hypocritical.

The 35K might be justified if it was a rare collectible in which case it's an investment decision rather than an ostentatious purchase.

I own a 1967 Breitling Navitimer that cost less than a tenth of that amount, but was still a lot (for me). It's appreciated in value and is beautifully engineered so to me it was worth every cent.
I really wish Bill Gates would just stop with the PR company approved image he puts forth for the sake of Microsoft and be himself. These little candid glances make him seem like a guy I would've loved to hang out with had I been there back then. (Especially the poker phenom stuff. I would've loved to have played him.)
General comments. As a preface, I established several online marketing teams at a multinational ad agency, back when things were new enough that they didn't have anything in place. I am super skeptical of most claims about online marketing.

Fundamentally, whatever you do, marketing has to be based on three things:

* Honesty (no b.s. about your products, don't mislead)

* Integrity (play hard but play fair)

* Respect (always treat your customers with the golden rule)

Never, ever sacrifice those values. Always gauge all marketing against those values. Seems obvious but many marketers (both client side and agency side) don't do this basic check.

Ok, onwards.

----------------------------------------

1. Make sure your site is as search engine friendly as possible. This is your foundation and without it any future promotion, marketing, word of mouth will fall flat.

2. Make sure your site reflects the impression you want to leave your customers/prospects minds. Be brutal in your evaluation. Do not skimp on this. First impressions on the web occur in a matter of seconds.

3. Measure measure measure. Get a baseline on traffic to your site. Use Google Analytics to track progress through the site. This is just like being a store owner and seeing who comes in, what merchandise they like and how long they stay.

3. Identify your targets. How do they communicate? Are they emailers? Twitterers? Where do they hang out online? Draw up a profile of your prospective customers. This is the beginning of an online media strategy.

3.5 Figure out what you want to tell these customers. If you have some existing customers talk with them. Craft your message. You may have multiple messages for different prospective customers.

4. Start slow, small and free. Drop honest, open non-spammy comments into forums that you are already a part of (no sock puppets). In other words: this should be dealt with much like you are dealing with any product you believe in. Be honest that it's your product, welcome feedback, but don't be shy about saying why it's good and why you feel it would be interesting to the people you're talking to.

5. Always approach any marketing as, fundamentally, a conversation. Never talk at people. Even print advertising should be one side of an ongoing dialogue with customers.

6. As you start to get the word out, watch traffic. See what works. Stagger your efforts so that you can track results easily. This is poor-man's media planning. Plot it out in a spreadsheet or proj.management app or calendar so you know when you'll start to communicate certain messages in certain channels.

I could go on about this. Not sure if this is the feedback you're looking for. Happy to write more.

With a normal web presence, it looks the same no matter how many people are visiting it.

With Facebook and other social idioms, it will be clear from the first pageview if noone showed up or if everyone left. The page/group's point in the hype cycle and demographics are obvious too.

Users can identify a failed launch or a ghost town at first glance, intuit that there's nothing there, and click away -- all without looking at your content.

It's interesting to see that there is about a 50/50 split of sites listing prices in increasing or decreasing order. Is there any information suggesting one direction is better than the other?
An IWC or Patek doesn't cost a few hundred dollars to produce, although I'm sure the real spread is horrific. Most luxury watches don't cost $35,000, either --- mid-4-figures is a more realistic estimate for the "BMW 3 Series" tier of watches.
I own an IWC that also doesn't cost anything resembling 35k --- I understand why people value them, and appreciate the engineering, but it's still not one of my prouder purchases (although it's far --- far --- FAR --- from my least proud purchase.)

Luck is an action, adventure film. The only thing sure about LUCK is that it will change. This film traces the path of various characters and their lives of how with time and circumstances, peoples life change with their changing luck. Luck is a story about this boy, Ram Mehra (Imran Khan), who is burdened by a lot of circumstantial problems, and reaches a point in life, where he has the capacity, but no opportunity, to come out of the mess that unfortunately life has offered him. http://onlinefreepictures.blogspot.com/2009/07/director-soham-shah-music-sulaiman.html
This is cool :) Really clean design!
A lot of highly specialized manual labor goes into the production of high-end watches, and above $20K they are usually made gold or platinum, so there are higher material costs as well.

Like anything else, prices of luxury goods are determined by the market- as long as someone is buying, they are by definition not overpriced. Comments here regarding "idiotic millionaires" and the like reek of class envy.
As an online organizer I can say that this is the best website I've discovered in ages. I am craving for this information and have been unable to find much sources that focus specifically on the issues that I face. Thank you for linking to this site! Really, thank you!

The article itself couldn't be truer. I see organizations going head over heals into social media thinking that there is some mother load of new "activity" at the middle of it. In reality all they are doing is waisting time that they should be spending doing "traditional organizing".

Community organizing is by far time better spent. I will submit to the experiences of a community organizer any day of the week. These people are the ones making any difference. They are the ones nurturing real connections with real people. By contrast, friending on Facebook is close to meaningless. We, online organizers, are here for a ride trying to figure out what to do with this relatively new medium (the Internet in general). The best tool an organizer has in her arsenal is a face to face meeting where you can build a real connection. This tool is taken away as soon as you move online.
Just launched Merecal, a site for tracking upcoming and new releases in books, movies, music and video games. It uses your favorite artists, authors, actors, directors, publishers, etc. to notify you when the releases you're likely to care about become available for pre-order or actually release.

My friend Kim Nguyen did the design: http://twitter.com/3am_studio

She's pretty awesome.
My one criticism - I think some of the excuse notes he rejects as lies are true - if they reflect anything similar to my childhood.
Except that's not what happened. MS didn't "get caught" for a GPL violation -- there was no license requiring them to submit the code.

They didn't do it out of the goodness of their hearts, correct, because MS is a corporation -- not a person. MS did this out of business sense -- increased interoperability with Linux just makes Windows/Microsoft all the more valuable.
I saw a article a few months ago about how the $5000 watch market is toast, and how the manufacturers' new strategy was to focus on the ultra high end ($100K+) market.

That is, people have stopped buying 3 series, so lets make up the difference by selling more Bugattis. Great idea guys.

You don't have to downgrade Firefox to use an old version of Firebug:

1) Uninstall Firebug 1.4.0.
2) Go to the URL "about:config".
3) Right-click on the list of preferences and select New -> Boolean.
4) Enter the name "extensions.checkCompatibility".
5) Set its value to false.

At that point you can install the old version of your choice from https://addons.mozilla.org/en-US/firefox/addons/versions/184....

I downgraded more or less immediately after 1.4.0 came out. 1.3.3 seems to work just fine with Firefox 3.5.
