I don’t like China (don’t know why 
), but I really like this tip:
In Firefox (Ubuntu), go to Edit => Preferences => Advanced => Encryption => View Certificates
Find CNNIC in the list, select & delete it asap 
More information why you should remove CNNIC from Root CA Certificate in Firefox: http://www.dinhnguyen.info/wordpress/2010/02/10/quan-trong-khua-firefox-3-6-va-bao-mat 
Today, all computers in my PHP department has been changed to Ubuntu 10.04. That’s awesome ^^
But my current project is running on out of date PHP & Zend Framework versions that was deprecated from PHP 5.3.0
Our Windows server running on PHP 5.2.x version, so we decided… downgraded to 5.2.x, too 
)
If you install LAMPP on Ubuntu 10.04, you’re getting PHP 5.3.2 & it is not the version you want. You have at least 2 options to install PHP 5.2.x:
- Download & build from source code
- Change source.list to get older version
Few days ago, I assigned a task to fix a problem: IE showed an error message box and crashed when load a heavy page (it took about 40-50s to load completly) .
I thought, maybe cause of problem is Javascript (syntax error) and I checked whole the page. Hix, nothing happened 
After I Googled, I found the main reason are:
So I refactored code by move all JS function call into $(document).ready( … ) (I used jQuery) to make sure the script will be excute after the page loaded successful. whew, the problem has been resolved

Chưa thử test với Jquery phiên bản mới nhất, mới chạy trên bản 1.2.1 (dự án hiện tại đang dùng ). Khi sử dụng $.ajax như bên dưới thì phát sinh lỗi:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | $.ajax({ type: "POST", url: document.location.href, data: "card_type=" + cardType + "&card_number=" + cardNumber, dataType: 'JSON', cache: false, success: function(responses){ if(!responses.has_error) { alert("Please enter valid Card Number."); return false; } } }); |
thì bị lỗi. Mặc dù response là {‘has_error’: false;} nhưng lại không nhảy vào khối lệnh IF.
Cách khắc phục rất đơn giản:
1 2 3 4 5 6 7 8 9 | ... success: function(responses){ var obj = eval('('+responses+')'); if(!obj .has_error) { alert("Please enter valid Card Number."); return false; } } |
Lưu ý: Chỉ xảy ra lỗi này nếu response là single object, nếu nó là mảng các object thì cứ $.each rồi get theo key, val thì lại ko sao
