Enable tethering shortcut found - iPhone 3.0 is Live! | 9 to 5 Mac
Topic: Technology 12:35 pm EDT, Jun 18, 2009

iPhone 3.0 is live! so we are going to repost our tethering tutorial with some big improvements. You now don't have to do any downgrading or torrenting. Seems you can just run a little command in terminal (Make sure you are on OS 3.0 on a 3G iPhone and iTunes 8.2):

defaults write carrier-testing -bool TRUE

After that, the steps become a lot more simple.

1. Download this file (for AT&T) and mount the disk image (thanks Gizmodo) for other carriers, try here.

2. Option-click on "restore" in your iTunes with your iPhone attached. Browse to the opened disk image file and hit OK. It will update phone settings for a few seconds.

3. You have tethering. Now go into your iPhone/settings/general/network/Internet Tethering and turn it on.

Boom - 3 steps to tethering...

Oh, and how to you like cut and paste and spotlight search?

FlexViz is a graph based visualization tool written in Adobe Flex. It has support for browsing a single ontology where the concepts are represented by nodes and the relationships between concepts (e.g. "is_a", "part-of") are represented as arcs.

The Start-up Guru
Topic: Business 2:10 pm EDT, Jun 16, 2009

Paul Graham:

It sucks to run a start-up. Running a start-up is like being punched in the face repeatedly.

We're mass-producing the start-up.

Everything around us is turning into computers. Everything is becoming software.

Justin Kan:

You could be working on the most boring piece of software, and you talk to Paul and you think, Man, I'm excited to go back to work.

Fred Wilson:

I don't mean this in a negative way, but Y Combinator is more like a cult than a venture capital fund. And Paul is the cult leader.

Max Chafkin:

Graham tends to have an air of impatience, as if even a momentary distraction is too much to bear.

Winifred Gallagher:

You can’t be happy all the time, but you can pretty much focus all the time. That’s about as good as it gets.

From the archive:

Marge: I'd really like to give it a try!
Homer: I don't know, Marge, trying is the first step towards failure.

Jeff Bezos:

People over-focus on errors of commission. Companies over-emphasize how expensive failure's going to be. Failure's not that expensive ...

The big costs that most companies incur are much harder to notice, and those are errors of Omission.

Johan de Kleer:

One passionate person is worth a thousand people who are just plodding along ...

Atul Gawande:

Let us look for the positive deviants.

An Introduction from 35K Feet

by Russell Jurney on June 9, 2009

My name is Russell Jurney, and I am a degenerate serial technology entrepreneur. I was a bad student. I’m a terrible employee. Yet despite an entrepreneurial career that might so far best be described as a negative feedback loop, I can’t stop founding companies. Being an employee without a stake is like playing poker for monopoly money. After a while, there is no thrill. I’m just going through the zombie motions, counting the days and the dollars in my account until I can drop out, start a company and feel alive again...

jQuery TOOLS - The missing UI library for the Web
Topic: Technology 9:10 pm EDT, Jun  9, 2009

What you really need are tabs, tooltips, accordions, overlays, high usability, striking visual effects and all those "web 2.0" goodies that you have seen on your favourite websites.

This library contains six of the most useful JavaScript tools available for today's website. The beauty of this library is that all of these tools can be used together, extended, configured and styled. In the end, you can have hundreds of different widgets and new personal ways of using the library.

Course Description

What do one mathematician, one artist, and one musician all have in common? Are you interested in zen Buddhism, math, fractals, logic, paradoxes, infinities, art, language, computer science, physics, music, intelligence, consciousness and unified theories? Get ready to chase me down a rabbit hole into Douglas Hofstadter's Pulitzer Prize winning book Gödel, Escher, Bach. Lectures will be a place for crazy ideas to bounce around as we try to pace our way through this enlightening tome. You will be responsible for most of the reading as lectures will consist primarily of motivating the material and encouraging discussion. I advise everyone seriously interested to buy the book, grab on and get ready for a mind-expanding voyage into higher dimensions of recursive thinking.

pero on anything - Hadoop Indexes
Topic: Technology 9:31 pm EDT, Jun  6, 2009

Just a simple order log with an unique identifier (id) and a single associated product and customer. Since we want to view our data from different perspectives we added two additional indexes on product and customer. (In this example we need two indexes because MySQL can only use the leftmost prefix of an index.)
Dumping the whole table as a single CSV-file into your Hadoop cluster would mean that you always have to use what (R)DBMS call a “full table scan”. It would be pretty much the same like removing all indexes from your MySQL-table. Try to search for all products a customer ordered without the index idx_product_customer. (In fact Hadoop would perform this full table scan an order of magnitude faster.) But it would be ridiculous to remove all indexes from your table. But that is actually what you did when you exported the whole table into a flat-file!
What you should do, and what we did with great success, is to split up your flat-file CSV and arrange the data so that you can decide beforehand which part of the data needs to be accessed. So let’s split up the data and simulate all of the indexes (besides the primary key, more on that later on). A file-system-layout could look like this:

So when searching all orders customer_1 placed, we just use this file-pattern orders/*/customer_1.csv. Remember: HDFS and MapReduce’s inputs (like FileInputFormat) support globbing.

Now we actually simulated indexes by partitioning the data!

From here on you can go into more detail depending on your data structure. As an example you could add the date- and id-range to the file name like this:
