In a fresh commit, Rails edge now has the ability to automatically add query plan info to the standard Rails logger:

A little shell script that lets you generate sparklines at the command line:

You can also pipe stuff to spark—see this wiki page for some clever examples.
This is pretty cute. I like the idea of putting inside your prompt, think there’s some interesting information you pull to put there.
Maybe a graph of how many times you had to...
Goodbye Web Workflow
Four years I abandoned all native desktop apps except an ssh client and a text editor.
I completely migrated my work life 100% to site-specific browsers with Google apps and 1Password.
We were living in the future and I loved it.
Fast forward to today: 1Password doesn’t work with Fluid anymore and Google’s new borderless-contrastless-whitespace interface is rolling out everywhere.

Super Fast SSH with ControlMaster Settings
Add the following to your .ssh config file: ControlMaster auto
ControlPath /tmp/ssh_mux_%h_%p_%r Then, when you open up a second terminal to the same remote server, it will automatically reuse the existing connection and the new prompt will appear almost instantaneously. It doesn’t have to re-authenticate for every new window. Amazing. If you also add ControlPersist 4h then the connection...
How do I switch between windows in Full Screen...
First follow these steps in OS X Lion:
Launch Safari
Cmd-N to open a new window (so you have 2)
Ctrl-Cmd-F to make one of the windows Full Screen
Is there a way to toggle between the windowed Safari and the full-screen Safari using just the keyboard?
I haven’t figured it out. Cmd-` (back tick) and Ctrl-F4 don’t work in this mode. And cmd-tab will get you to ONE of them, but not...

You rent a hotel room. You put a book in the top drawer of the bedside table and go to sleep. You check out the next morning, but “forget” to give back your key. You steal the key!
A week later, you return to the hotel, do not check in, sneak into your old room with your stolen key, and look in the drawer. Your book is still there. Astonishing!
How can that be? Isn’t the...

All they did was change account IDs in the URL and voila, they were in someone else’s account. This makes me so sad.
At least they have 2 factor authentication and Site Key and ridiculous password length and content requirements that are incompatible with any of my other password algorithms and auto-logoff because those things aren’t at all annoying and really help protect my info.

Why I hate agile development
2011 is the 10 year anniversary of the Agile software development methodology (or at least the anniversary of the term).
Ask ANY developer or project manager if they practice agile development.
90% will say yes.
Now ask if they use scrum, velocity tracking, XP, TDD, FDD, or pair programming. The number will now be closer to 10% (followed quickly by “but we’re still agile”).

“Fixed ‘Web page loading slow issue’”
– From the changelog on my Netgear router firmware.
I ponied up $130 on this router, which I thought was a lot of a home wifi router, but I was tired of having to reboot my old Linksys.
The funny thing is that this upgrade actually seems to have fixed that exact problem.

Goodbye Quicksilver
The best part about using an SSD with OS X is that, for the first time, Spotlight is actually usable. And it’s great!
This means I can finally get rid of Quicksilver, which I’ve used and loved for 10 years but is by far the buggiest piece of software I’ve ever relied on.*
* Not totally true. The Treo 750’s text messaging application on Verizon was much buggier and I...

exceptional-blog:
Exceptional tracks errors in Ruby apps. It’s wildly popular. It now processes a few hundred million errors per month for over 10,000 apps—including some very big and popular ones.
So if my math is correct, ~300 million exceptions per month for 10,000 apps works out to about 30,000 exceptions per month, or one thousand exceptions per day per application!
That’s a...

The Significant Decline of Spam - Slashdot →
According to Commtouch, the world saw an 18% drop in spam in October, most likely due to the closure of Spamit, an organization behind a huge percentage of the world’s spam.
The article doesn’t have too much more to say about it, but I was shocked that spam was actually decreasing, and by a huge percentage.

Are you clicking more ads with Google Instant?
SearchEngineLand has a post noting that clicks on sponsored links have gone up dramatically (5%) since Google launched Instant Search.
I know I’ve been clicking SIGNIFICANTLY more ads since Instant Seach was released. According to my Google Web History, I have clicked 5 ads since Sept 8, but just 4 ads for the previous 9 months in 2010.
Why the increase, you may ask? More impressions? More...
Redirect ALL Output to a File
Every good little hacker knows you can redirect STDOUT to a file like so:
blah > out.log
And you can redirect STDERR to STDOUT to a file like so:
blah 2>&1 > out.log
But what I didn’t know and just learned, is that you can redirect EVERY output stream to a file at the same time like so:
blah &> out.log
Useful.

Is the Google-Verizon Deal a Sheep in Wolf...
For years Google has fought for a free and open Internet. That’s why this deal with Verizon is so surprising.
My secret fantasy is that the Google-Verizon deal is actually the search giant punking the entire country. In a massive instance of reverse psychology, Google is saying to consumers and the FCC: “Fine. You want to allow a tiered internet? No problem. Sign us up. Just try...
