arockwell··on How a fake Justin Bieber "sextorted" hundreds of girls through Facebook
You must be at least 13 https://www.facebook.com/help/?faq=210644045634222

arockwell··on Mark Cuban: If you want to see more jobs created -- change patent laws
Sorry, I should have been more specific. My point is more that the problem is systemic. You also can't patent something that has prior art, but it happens all the time.
arockwell··on Mark Cuban: If you want to see more jobs created -- change patent laws
Bussiness processes are already unpatentable.
arockwell··on Sqlite and couchdb creators announce unQL. SQL for NoSQL
SPARQL is substantially less powerful than SQL. No delete/update/insert statements, no subselects, and limited aggregation and functions. I've used SPARQL a lot in the past year and I am constantly running into limitations.

Performance has also been very poor (we use Jena SDB). I don't know if poor performance is an implementation problem or an overall weakness.

arockwell··on AWS drops bandwidth pricing
Can you elaborate on this? Not disputing your point, but it would be nice if someone could jump in with some real world numbers or a rule of thumb.
arockwell··on You're Using JSON, Why not MessagePack?
This is important if you want to use JRuby.
arockwell··on Don’t scale: 99.999% uptime is for Wal-Mart
That's not too bad. But does that all add up to more than 9 hours a year of downtime? If so, you're already doing worse than 99.9% uptime.

I would also bet your uptime is worse than you think if you're not actively measuring it. However, I'm sure it is "good enough". I doubt it is worth spending an order of magnitude more money to get better than 3 9's for your business, which is more or less the point of the article imo.

I find the percent availability -> hours of downtime chart on wikipedia to be a really helpful reference for these types of discussions: http://en.wikipedia.org/wiki/High_availability

arockwell··on Don’t scale: 99.999% uptime is for Wal-Mart
What is your actual uptime?
arockwell··on Rush: the ruby shell
I think this is pretty cool. I've wondered what a ruby shell would look like. I don't "get" bash at all, but I find ruby very natural. I've gotten better at writing bash one-liners for basic sysadmin tasks, however anything more complicated is hopeless. I've found it easier to write chef scripts to automate any server task than using bash.

The ability to easily execute commands on several remote servers is really appealing. At work, I only need to be able to ssh to 5 different servers and I frequently don't have a free screen terminal.

arockwell··on Square mobile payment system goes live on iPhone, iPad, and Android this week
Waiter's already have plenty of time to get your credit card information. It does not take any longer to take a picture of the front and back of your card. Waiter's (and other POS workers) have been stealing credit information in low tech ways since credit cards have existed.
arockwell··on The Original Techcrunch 40: Where are they now?
I would love to see this as well, but I doubt this information is available for most (any?) of the companies.
arockwell··on Why is JSON so popular? Developers want out of the syntax business
My gut feeling on this is that almost anyone can recognize that writing JSON like that is wrong. However, trying to determine if

  <person first-name="John" last-Name="Smith" />
is better than

  <person>
      <first-name>John</first-name>
      <last-name>Smith</last-name>
  </person>
is often very difficult. In the wild, I've seen both strategies used depending on the situation.
arockwell··on Bill Gates and Steve Jobs wanted to sue Sun
No new information in this article. Its just a rehashing of Jonathan Schwartz's blog entry: http://jonathanischwartz.wordpress.com/2010/03/09/good-artis...
arockwell··on 'Under God' Held Constitutional in 9th Circuit Pledge Ruling
The words "under God" did not come from the Founding Fathers, they were added by Eisenhower in 1954: http://en.wikipedia.org/wiki/The_Pledge_of_Allegiance#Additi...
arockwell··on All the wrong reasons for Stack Overflow's VC chase
The definition I've seen given by PG is anything that scales up. In other words, a business that sells a product that can be used by many users. A small business is usually something that offers a service (a restraunt, a barber shop, or a consulting firm).

Funding has nothing to do with it.

arockwell··on What Pythonistas Think of Ruby
Python doesn't have multiline lambdas, so there is no way to create an api similar to rake's:

  task :name do |t|
   # do stuff
  end
I'm not sure what's the closest equivalent syntax you could create in python.
arockwell··on Learning to forget: Why web companies need to archive data
Deleting information posted publicly isn't practical. Your posts are likely to be archived in numerous places (e.g. google cache or archive.org).
arockwell··on IBM's infamous "Black Team" (2002)
I think the important part is to allow these groups to be self-selecting. In other words, the smartest people should gravitate towards each other if they are allowed to. For a really interesting take on how to do this take a look at: http://en.wikipedia.org/wiki/WL_Gore_and_Associates#Gore_Cul...

I couldn't find a good source for how many employees they have, but its in the thousands, so they have been able to make this work on a large scale.

arockwell··on Calculated Risk: U.S. Population Distribution by Age, 1950 through 2050
If you broke the 80+ age range to 80-85, 85-90, 90-95, and 95+ each group would be progressively smaller than the 75-80 age group (I suspect anyways, I don't know the actual data).
arockwell··on In-Field Labels: A Better Way + jQuery Plugin
What's worse is that this doesn't gracefully degrade. If you have javascript disabled your text will be written over top the label text and is completely unreadable.
arockwell··on Ask HN: review my app: Search engine: ruby/rails, javascript, CSS, browsers
The __.__ as a seperator is way too visually distracting. Why not just a '|'? Also, 4 levels might be too much information.

The result links are hard to read as well. I have no idea what the numbers mean... perhaps it should just say result? Whitespace between each line would help readability as well. The whole result page is wall of text.

arockwell··on Ask HN: review my app: Search engine: ruby/rails, javascript, CSS, browsers
I'm not sure what this tool does. Can you give a clearer explanation of what this tool is for, or maybe an example of how it would be useful?

Also, the front page of the site needs to make this goal explicitly clear. Instead, the front page gives almost no indication of what this is for, and shows a lot of weird sounding empty result sets.

arockwell··on 60 million stung in social networking rip-off
Don't most terms of service have a clause in them similar to that?
arockwell··on Google App Engine Broken For 4 Hours And Counting
99.99% is only 52 minutes of downtime a year... I don't think any of S3, Rackspace, Goole AppEngine, or even www.amazon.com have uptime that good this year.

Getting that kind of uptime is much harder than it sounds and for a lot of websites not worth the extra cost. How much money would pay to go from 99.9% uptime (~9 hours /year) to 99.99% (52 minutes)?

arockwell··on Cognitive enhancement drug may also cause addiction
Strattera has the same concentration improving effects of stimulants and is not habit forming.
arockwell··on Poll of Facebook Users Finds 94% Hate Redesign
The one thing you're forgetting is that this happens _every_ time there's a new website redesign for Facebook. Its actually very typical for this to happen in general. People despise change will complain about a new design even if the design is much better. In a couple of weeks no one will even notice or think much of it.
arockwell··on My Life in Child Porn
Most of the growth is thanks to our drug policy.
arockwell··on Why TV Lost
This is pretty close to reality in the form of the Eye-Fi: www.eye.fi. The sd card automatically uploads pictures/video over wifi to your computer and/or certain social networking sites.
arockwell··on IPhone’s Misplaced Decline Button?
Nielsen readily admits that the usability of his site is bad, but it is distinctive looking.
arockwell··on Python Is Not Java
Try JSON:

  { 
  "directories_to_backup": [
    {"directory_name": "/media/programming",
     "exclude_dirs": ["/media/programming/log_files",  
                      "/media/programming/temp_files" ]
    },
    {"directory_name": "/media/documents",
     "exclude_dirs": ["/media/documents/archive"]
    }
}

Also, why not just use a python data structure? Do you really need a plain text config file?
