Re:Securing an Ubuntu Server on Saturday March 12, 2011 @08:42PM (#2318032)
Great advice! You sound like you have a lot of experience in server security.

What is your recommendation on strong passwords? Also, should all passwords on a system be different (login passwords for different servers, email passwords, etc...), and if so, how do you keep track of all of them?

Thanks

What if you can't disable root login (i.e. it's a cloud server)?
Re:Hummingbird, Real Time Web Traffic Visualization on Friday February 25, 2011 @05:16PM (#2264002)
Thanks for creating this and open-sourcing this great app!

One question: Does aggregates.html work? I can see that metrics are being recorded in mongodb, but it does not load the js properly to display the hourly, daily, and weekly metrics. I can get everything else to work fine (in index.html). Thanks!

Re:Things to Never Say While Negotiating on Saturday February 05, 2011 @06:18PM (#2184350)
Is there any way to gain practice on negotiation? As an entrepreneur, are there any resources on the internet where you can "practice"?

The only thing I can think of is playing poker or something at the casino...

Re:Y Combinator’s Paul Graham On The $150K Per Start-Up Offer on Tuesday February 01, 2011 @07:08PM (#2168158)
What do you mean by runway?
Re:Y Combinator’s Paul Graham On The $150K Per Start-Up Offer on Tuesday February 01, 2011 @04:25PM (#2167478)
Could someone help me run the numbers? What will $150,000 be used for on an average YC startup?

$150,000 will allow the startup to hire 1 or 2 engineers in the short-term. Is that the real use of the $150,000?

What other expenses do they spend good money on?

Another way to look at this question: If you were a new startup in YC, what would you spend the 150,000 on?

Re:Photography - 24 hour shot on Monday January 31, 2011 @04:59AM (#2160908)
It looks really cool!, but I don't understand how it is a 24 hour shot. It just looks like a tiny planet with a house on top. Could somebody please explain the image?

Re:Rent vs. Buy Visualization of Top 50 Cities on Monday January 24, 2011 @04:59PM (#2136946)
There are many cities in the county of San Diego. The city of San Diego (where you are suggesting that the 200k number came from) is about 10-20% of the size of the county of San Diego.

They should make the size of the bubble smaller to only cover the area of the city like you are saying.

Re:Rent vs. Buy Visualization of Top 50 Cities on Monday January 24, 2011 @04:45PM (#2136899)
The statistics on this infographic are misleading. It does not cost 200,000 to buy a house in San Diego or San Jose!

Maybe the average for downtown San Jose and San Diego are close to 200k, but that is the poorest area of both cities and not what should be used to compare. The green bubble on the point for San Diego should be much much smaller in radius(like miniscule), otherwise you think the 200k number refers to the entire city!

People should not be using this to make informed decisions (obviously).

Re:Ask HN: Fastest way to $2500 month? on Sunday January 23, 2011 @04:16AM (#2132104)
I agree. Generally, "desperate" means taking any (reasonable) job offer you can get.
I wish there were more people like Mister Rogers.

You can't help but feel better about the world after listening to this video.

Re:Google to Launch Groupon Competitor on Thursday January 20, 2011 @09:18PM (#2126175)
With the 200+ million gmail email addresses that Google has access to, Google can instantly become a major competitor to Groupon & LivingSocial assuming a certain percentage of gmail users agree to try it.

It seems that each large internet company has its own deals site now: Google with Google Offers, Amazon with LivingSocial, eBay with Groupon, and Facebook seems to be developing its own type of daily-deals advertising.

I wonder what Apple and Microsoft will do. Both of them probably have something in the works....

Re:LivingSocial Hacked on Thursday January 20, 2011 @02:01AM (#2122941)
Don't get too excited.

LivingSocial disabled this already (the trick doesn't work any more), and all people who tried this trick earlier today will simply get an email tomorrow saying that they are not eligible because they ordered more than 1 gift certificate.

There's simply too much money at stake for LivingSocial not to make sure that people only get 1 gift certificate each.

Re:Google Voice now lets you port your own phone number on Wednesday January 19, 2011 @11:53PM (#2122696)
Does anybody here also notice a lag during Google voice calls?

Sometimes the lag is up to half a second or one second, and it can really make conversations difficult because you start interrupting the other person (even though you don't realize it and think you started talking when there was a lull in the conversation).

Re:Introducing AWS Elastic Beanstalk on Wednesday January 19, 2011 @03:45AM (#2119182)
Amazon's execution with EC2 over the past few years has been excellent. If Amazon makes a Rails version of Beanstalk, Heroku should be worried as Beanstalk could take some market share from Heroku.
Re:Introducing AWS Elastic Beanstalk on Wednesday January 19, 2011 @03:41AM (#2119171)
Just to be clear, this is only for Java apps right? This does not include PHP or Python?
Re:How Much Does a Single Search Cost Google? on Sunday January 16, 2011 @10:06PM (#2111065)
What would also be interesting to know is what the average CPM of the Google Search Engine is, and compare this with Bing or Yahoo.

I would think (but cannot confirm) that Google makes more per search than Bing or Yahoo.

Re:Airbnb (YC W09) Grew 800% in 2010 on Sunday January 16, 2011 @03:19AM (#2108993)
Just wondering, how many people here have used Airbnb? I would think a large number of HN people would use it.

Are you looking for full-time engineers?
Re:Ron Conway Explained on Tuesday January 11, 2011 @03:58AM (#2091402)
At what size for a consumer app do you start getting "noticed"?

I would very interested to hear what kind of product you made.

Re:The anatomy of a WordPress theme (Infographic) on Tuesday January 11, 2011 @03:03AM (#2091306)
Excellent graphic describing wordpress theme file structure.

It would be very interesting to know if other CMS's share a similar file structure. How does this compare to Drupal or Joomla for example?

Re:$100K in 4 months: A niche app's path to App Store success on Tuesday January 11, 2011 @02:52AM (#2091296)
Congratulations! $100k in 4 months is definitely a success. Also, thanks for sharing your numbers and crafting an excellent writeup.

How exactly do you get into this network? Is his network closely connected to the PG/YC network?
Re:Plupload - A beautiful file uploader powered by jQuery on Monday January 10, 2011 @10:18PM (#2090712)
I don't understand. Why is this any different than most jquery upload plugins?

Also, I tried the demo and didn't want to use Google Gears. After I didn't allow Gears permission, the uploader stopped working. This is a problem.

Re:PHP Fog Raises $1.8 Million To Be The Heroku Of PHP on Monday January 10, 2011 @08:03PM (#2090415)
Just wondering, how much control do you have over configuration settings for Heroku?

I imagine you could save a lot of money by optimizing apache/mysql rather than using the default configuration Heroku sets.

Re:Myspace to lay off over half of staff tomorrow on Monday January 10, 2011 @07:58PM (#2090394)
At least this was done after the holidays (unlike Yahoo which gave it's employees an early christmas present).
Re:$100K in 4 months: A niche app's path to App Store success on Monday January 10, 2011 @07:56PM (#2090391)
If the author is here, could you comment on how often people use your app? Are these statistics commonly measured for iOS apps?
