The most fundamental difference between hash and nested loop joins

Basically the most fundamental (or biggest or most important) difference between nested loop and hash joins is that: Hash joins can not look up rows from the inner (probed) row source based on values retrieved from the outer (driving) row source, nested loops can. In other words, when joining table A and B (A is driving table, B is the probed table), then a nested loop join can take 1st row from A and perform a lookup to B using that ..

Sometimes I’m asked to write or speak about something with very little preparation. In these situations, I need a tool that can help me: Organize my thoughts quickly Prioritize the wheat before the chaff Maintain a coherent train of thought I find a very useful structure for archiving this to be what I call “three-by-three”: Three main points with three subpoints each. Forcing myself to keep to a structure will make my thoughts flow more qu..

A while back, I was poking around LLVM bugs, and discovered, to my surprise, that LLVM doesn’t support the va_arg intrinsic, used by functions to accept multiple arguments, at all on amd64. It turns out that clang and llvm-gcc, the compilers that backend to LLVM, have their own implementations in the frontend, so this isn’t as big a deal as it might sound, but it was still a surprise to me.

Pair programming and test-driven development are some of the practices that are most often talked about and least often actually understood. So I’ve decided to undertake the task to teach myself to program a simple, yet realistic problem with a pair programming partner. The goal is to create an entertaining and realistic performance that portrays what it feels like to work like this. I’ve been extremely lucky. I’ve found not one, but two pr..

The below is a quick Python snippet which I use on a day to day basis for weeks, then promptly forget. Essentially its reading from standard input and then doing something with it. Very useful when you are trying to process data on the command line and have forgotten how to use awk/sed properly and grep has run out of steam. import sys import re for line in sys . stdin: values = line . split( ',' ) pri..

I'm a very new user of Git. I've been using it for some time to download and install repositories, like most people, but didn't use it for source control yet. Recently I've started using it, though, so I've been bumping into small problems along the way. One problem I've had was with trying to find out how to keep certain files out of a repository. I had tried Googling a few terms, but that only brought up results for actually removing a fi..

I ran across this post yesterday, by css-tricks.com. They had a little UI design competition where they asked participants to design and develop a UI for editing and deleting items of a list. It's a cool idea for a competition and you can read the whole thing here: https://css-tricks.com/ui-pattern-ideas-list-with-functions/ I chimed in at the comments, but realized quickly that this should become a blog post by itself.

According to Wikipedia, stenography or shorthand is “is an abbreviated symbolic writing method that increases speed or brevity of writing as compared to a normal method of writing a language”. Just as a stenographer learns to take down information really fast, a good programmer can learn to write code really fast by taking advantage of his or her tools. In this post I’ll show you my secret code stenography tricks.

After the fuss of the last two weeks because of CVE-2010-3081 and CVE-2010-3301, I decided to take a look at a handful of the high-profile privilege escalation vulnerabilities in Linux from the last few years. So, here's a summary of the ones I picked out. There are also a large number of smaller ones, like an AF\_CAN exploit, or the l2cap overflow in the Bluetooth subsystem, that didn't get as much publicity, because they were found more q..

I hosted the application on Heroku’s node.js beta preview and used a free CouchOne instance for the data store. Although I encountered some difficulties, I learned some important lessons that I thought I’d share. Tag your last successful Heroku deploymen..

Everyone has heard horror stories about pointy-haired-bosses counting lines of source code to track the progress of a project. We roll our eyes and laugh at their stupidity. But before you laugh too much, you might want to find out whether you’re really any better. Most of what software projects measure are not things we care about. Not things we really care about. Do you really care about the number of coding standard violations in your co..

It strikes me now, many years later, that what I'd built was essentially a PHP markov chain Several months ago I was wondering to myself if you could detect patterns in a list of words and then use those patterns to generate a new list of fake “words”. A kind of a flavored Lorem Ipsum generator, where I could change the feel of the sentences by switching out the data set. I’m sure thousands of developers have done this before me – but..

How many steps do you need to perform to release a new version of your software? Do you even know? Releasing frequently requires the release process to be as streamlined as possible. A good way to get started is to write a step-by-step instruction that explicitly state everything that needs be performed for an installation or upgrade. Then get to work cleaning it up: Make sure you can build and package everything that’s needed for the insta..
