How to disable the most visited thumbnails in Chrome V29+?

Well, I knew you were looking for it! Don't ask why! Yeah, I had the same feeling.

And here it is:

1. In address bar, type in: chrome://flags/ and hit Enter
2. Search for 'Enable Instant Extended API Mac, Windows, Chrome OS' on the page
3. Select the most wanted value - wait for it - 'DISABLED' from the drop-down list
4. Restart Chrome

Open a new tab, and tell me how much you missed it......

Good luck!

MacBook Air Wifi slowness resolution before Apple fix it

Wifi is barely working on my MacBook Air with Mountain Lion, both at work and home. Symptom might be seen as the following:

• On connection to your Wifi, it works for the first a few page load, then slows down and even lose connection.

I've searched online and there're quite a few "fixes" and only the following works for me and I also consider it as "an easiest fix" for now.

1. Go to "System Preferences" -> "Network".
2. Select your "Wifi", click on "Advanced".
3. Select "Hardware" tab.
4. Choose "Manual" from the "Configure" dropdown.
5. Choose "Custom" from the "MTU" dropdown.
6. Fill in "1453" in the blank box.
7. Save, turn off then turn on your Wifi.

Hosts file gets reset after reboot on Mac Lion

I updated my hosts file on my Mac by doing the following:

sudo vi /etc/hosts

but it was reset every time when system was rebooted.

The reason being I have installed Cisco AnyConnect VPN client, which keeps a separate copy of the original hosts file, and will restore my hosts file from it each time after reboot.

ls /etc/hosts*   =>  /etc/hosts   /etc/hosts.ac    /etc/hosts.equiv

So the solution is to update both "/etc/hosts" and "/etc/hosts.ac" to keep them in sync.


Hope this helps you too.


Thanks.

An error occured while installing ruby-usb (0.2.1), and Bundler cannot continue.
Make sure that `gem install ruby-usb -v '0.2.1'` succeeds before bundling.

Why? -- Because I didn't follow the instructions!

Well, after coming back and reading through all the instructions on Blinky Wiki page, I thought it would be very easy, but it turned out not.

Install Ruby 1.9.2 with XCode 4.3+ on Mac OS X 10.7

Is this what you're looking for?

rvm install ruby-1.9.2-p290 --with-gcc=clang

Problem solved?

Good luck and thanks for trying.
