Linus Torvalds on Git

Taken from “Linus Torvalds goes off on Linux and Git” and presented without comment.

Git has taken over where Linux left off separating the geeks into know-nothings and know-it-alls. I didn’t really expect anyone to use it because it’s so hard to use, but that turns out to be its big appeal. No technology can ever be too arcane or complicated for the black t-shirt crowd.

You’ll spend a lot of time trying to get your head around it, and being ridiculed by the experts on github and elsewhere. I’ve learned that no toolchain can be too complicated because the drive for prestige and job security is too strong. Eventually you’ll discover the Easter egg in Git: all meaningful operations can be expressed in terms of the rebase command. Once you figure that out it all makes sense. I thought the joke would be obvious: rebase, freebase, as in what was Linus smoking? But programmers are an earnest and humorless crowd and the gag was largely lost on them.


Edit: The originating post is marked as ‘satire’. I missed this at first, but after I read it in that context it was obvious. Still, some of the points in the quote ring true to me even if Linus didn’t say them.

Getting started with node.js on Windows

The title is somewhat misleading. As of right now, node.js doesn’t run on Windows. You have to run it on some kind of *nix/BSD based system. But there is a somewhat low footprint way to run it and play around with it on your Windows box.

Step 1 – Download and install VirtualBox orVMWare Player. I chose VirtualBox. It’s free, and supports 64-bit guests.

Step 2 – Download The Turnkey Linux core appliance and unzip it somewhere. This handy little virtual machine is based on Ubuntu and give you a basic command line environment with networking.

Step 3 – Import the Turnkey core appliance into VirtualBox.



Choose the .ovf file in the Turnkey directory you unzipped earlier.


Click next and review the settings, making any changes as you see fit. The defaults should work fine. Then click import.


Once Virtualbox finishes importing the virtual machine, you can start it up.

Assuming your network is configured correctly, the virtual machine will grab an IP from your DHCP server and be ready to go.


Step 4 – At this point you can either SSH into the virtual machine or you can connect using the web shell at the address indicated in the startup screen. Initially you can connect using as the root account with no password. You are almost ready to start installing node.js. First type “apt-get update” at the command line to make sure you have all the latest package information.

Step 5 – Install the developer tools you need to get and build node.js. Node.js isn’t packaged as a binary, you have to build it from source. Luckily it includes it’s dependencies and is pretty easy to build. But first we need to get a compiler. Type “apt-get install build-essential” and hit return. A lot of text will fly past, if it asks you if you want to go ahead press “y”.

Step 6 – Install Git. Now you’ve got a compiler installed, we have to install git so we can fetch node.js from the repository. At the command prompt type “apt-get install git”. Once that is complete, type “apt-get install git-core”.

Step 7 – Clone the node.js Git repository. If you want to put node.js is a specific directory, go ahead and make it then “cd” into the new directory. At the command prompt, type “git clone git://github.com/joyent/node.git“.

Step 8 – configure the source for building. type “cd node” and change into the node directory that Git created. Type “./configure”. You may see a few “fail” messages. Don’t worry about them.

Step 9 – Build node.js. Type” “make” at the command prompt. Get a sandwich or a nice cool drink. It doesn’t take very long, but it’s not very exciting unless the Matrix screensaver is your favorite screen saver.

Step 10 – Install node.js and start build applications. Type “make install” once the build is complete. Once that is complete,you can type “node” at the command prompt and you should see the standard help information fly by.

Building a node module or application is beyond the scope of this short tutorial. I suggest reading up at the Node.js site.
