I’ve been using tail to watch my log files for years:

tail -f log/production.log

It works great all the time, until you want to search for something, then you have to ctrl+c and open the file in less or vi.

Maybe there is a better way? After some googling, I found less is the answer:

less +F log/production.log

less +F works exactly like tail -f, with more:

• Simply press ctrl+c to switch to editing model, so you can scroll backward and using any more/vi command, such as /pattern to search
• Press shift+f again to switch back to tail model

Anyway, just run man less to find some more information.

If you think you are beaten, you are

If you think you dare not, you don’t,
If you like to win, but you think you can’t
It is almost certain you won’t.

If you think you’ll lose, you’re lost
For out of the world we find,
Success begins with a fellow’s will
It’s all in the state of mind.

If you think you are outclassed, you are
You’ve got to think high to rise,
You’ve got to be sure of yourself before
You can ever win a prize.

Life’s battles don’t always go
To the stronger or faster man,
But soon or late the man who wins
Is the man WHO THINKS HE CAN!

– Walter D. Wintle

I believe you already noticed the twitter updates on the sidebar. Yes, I am attending WWDC 2009 this week. It is a great conference and I believe you’ve already got the news from it too.

Just a day before I came here, I’ve launched a website for this event:

http://wwdc2009.com

Here’s how it works:

1. I create a new twitter account @2009wwdc
2. I use this account to follow all the people who attend this conference, not the one who just talk about this
3. I’ll follow people who will tweet the important things, especially the kind of people who don’t care NDA that much.
4. Server will automatic pick up who I follow and collect all their tweets and stats
5. Tweets are searchable on the site
6. Will archive the site couple of weeks after the conference ends

If you want to know more about WWDC 2009, it is the site you should go.

Enjoy!

Have Fun!

The *awesome* Palm Pre first-boot welcome video. I don’t know of any other phone that shows something as pretty as this when you open the box!

Indeed promising! Even the name “Natal” sounds like “邋遢” in Mandarin.

Compatible with any Xbox 360 system, the “Project Natal” sensor is the world’s first to combine an RGB camera, depth sensor, multi-array microphone and custom processor running proprietary software all in one device. Unlike 2-D cameras and controllers, “Project Natal” tracks your full body movement in 3-D, while responding to commands, directions and even a shift of emotion in your voice.

In addition, unlike other devices, the “Project Natal” sensor is not light-dependent. It can recognize you just by looking at your face, and it doesn’t just react to key words but understands what you’re saying. Call a play in a football game, and players will actually respond.

Coda is one of my favorite Editor/Site Manager/Terminal tools. It has everything I need for the web development.

Anyway, even I get no benefits from promoting them, I still want you to know:

Yes! Coda, Transmit, CandyBar, and Unison are 50% off. It’s never happened before, and it’ll probably never happen again. Serious.

Just bought my ticket for WWDC 2009!

Today is the last day for early bird price (Saving $300). I got it in Canada for CAD $1699. Really not cheap.

Funny story, I thought I can buy it cheaper in US store, but it turns out even worse. The final price will have tax be added onto original price USD $1295, which will be USD $1414 in total. And USD $1414 is about CAD $1728 as of today.

Look forward to it!
