I'm running Fedora 12 with VMware Worksation 7 installed. Since the last kernel updated I can't start vmware, it always shows a vmnet errors.
After trying to google many times, I found a solution from fedoraforum :D

First, I must install "kernel-devel".
Then, I run these commands with sudo (my account is in sudoer group)


# cd /tmp
# tar xf /usr/lib/vmware/modules/source/vmnet.tar
# nano vmnet-only/vnetUserListener.c (near line 37 add #include "compat_sched.h")
# tar cf /usr/lib/vmware/modules/source/vmnet.tar vmnet-only
# tar xf /usr/lib/vmware/modules/source/vmci.tar
# nano vmci-only/linux/vmciKernelIf.c vmci-only/include/pgtbl.h (add #include "compat_sched.h" around 30 line)
# tar cf /usr/lib/vmware/modules/source/vmci.tar vmci-only
# vmware-modconfig --console --install-all

Cheer, now vmware can work fine.

Mỗi lần phải đưa ra một quyết định là một lần cảm thấy khó khăn. Có lẽ mình không quyết đoán lắm trong những tình huống lựa chọn như vầy. Cùng lúc đưa ra 3 lựa chọn, đi thẳng, quẹo trái và quẹo phải, không thể nào nhắm mắt bước đại được, phải suy nghĩ, phải lựa chọn, để rồi sau khi suy nghĩ xong, lại có cảm giác buồn buồn.
Khi đưa ra quyết định cũng là lúc phải vứt bỏ, quay lưng. Buồn hơn khi quay lưng, chấm dứt với những cái đã dần trở nên thân thuộc với mình.
Nói sao thì nói, quyết định không thể không đưa ra, quay lưng là không thể tránh khỏi, buồn, vương vấn là không thể không gặp, đành vậy thôi, cuộc sống mà, làm sao tránh khỏi được, nhỉ?
Vòng tròn lẩn quẩn :(

   Quay qua quay lại vậy mà đã hết năm.
Một năm, ngoại trừ 3 tháng ở nhà chơi, 2 chỗ làm, tính đi tính lại, được nhiều, đầu óc thoải mái nhiều, tuy là chỗ làm chưa ưng ý lắm, chưa gặp sức ép nào đáng để gọi là sức ép, nhưng bù lại học được nhiều, coi như là bàn đạp vậy.
Hết năm, nhận được lời đề nghị từ 2 chỗ mới, 1 fulltime và 1 parttime, cơ hội nhiều, mong đợi nhiều, hy vọng là không phải thất vọng với kỳ vọng (không lấy gì làm cao sang của mình :">) Trước hết là nắm bắt đã.
   Ngoảnh đi ngoảnh lại, 365 ngày chỉ như cái chớp mắt, chớp càng nhiều, thời gian càng qua nhanh. Thôi, ngủ đã :">

Here is a really nice post by Antonio Lupetti at http://woork.blogspot.com. Thanks for great post.


In the last weeks I frequently received a question about how to use CSS3 border-radius property to draw HTML elements with rounded corners in Internet Explorer. How you know CSS3 border-radius property is natively supported in Safari, Firefox and Chrome but for some mysterious reason this property is not supported in Internet Explorer.

So to draw rounded corners in IE you have to use some trick, for example using CSS classes with a background image (take a look at this post).

The simpler and quick solution I know to draw rounded corners in every browser is to use a mix of CSS3 and JavaScript. CurvyCorners is a free JavaScript library for creating gorgeous rounded corners for HTML elements. The final result looks like this:

I'm a big fan of jQuery and I always use jQuery for my projects, but, when I changed my job and came to my current workplace, I must use ExtJs, another really cool Js framework. This took me alot of time :( since I've read the tutorial named "Extjs quick start guide for jQuery Developers" written by Anis Ahmad at http://www.ajaxray.com. Hope it can help you :) ( The original post here. Thanks Anis Ahmad.  )

I’ve seen many people (including myself) trying out the power of jQuery for once and then getting stuck with it. Why not? It’s one of the coolest and smartest JavaScript library out there. However, I have broken out from the circle and found that Extjs is another great mentor in the field of JavaScript libraries. Especially, I think it’s UI components are unbeatable (Dojo can be a nearest candidate).

If you are habituated to think JavaScript coding in the syntax of jQuery, you can start working with ExtJS right now (with a few twist)!  What you need is some little tuning in concept and syntax. Today I will be trying to explain how to do this in 6 important points :

1. Document is ready - How to get the our document ready and where to start.


2. Selecting elements - How to select elements in Ext.


3. Dom scripting - Changing on and in the element.


4. Ext events - Assigning and firing events.


5. Ext Components - The powerful alternate of jQuery UI.


6. Ajax - Making Ajax request in Ext.

Document is ready

<script type="text/javascript">
$(document).ready(function() {
  // do stuff when DOM is ready
});
</script>

<script type="text/javascript">
Ext.onReady(function() {
  // do stuff when DOM is ready
});
</script>

Selecting elements

// Selecting by ID in jQuery
var myDiv = $("#element-id");

// Selecting by ID in Extjs
var myDiv = Ext.get('element-id');

// Perform some action on it
// Add a class
myDiv.addClass('my-class');
// Set the width 100 px, 
// true is for applying default animation on change
myDiv.setWidth(100, true);
// Retrive some information of the element
// Get the elements box info as object {x, y, width, height}
var box = myDiv.getBox();

// Select elements with CSS Selector
var imgs = Ext.select("#my-div div.member img");
// or select directly from an existing element
var members = Ext.get('my-div');
var imgs = members.select('div.member img');

// Now, any Ext.Element actions can be performed on all the elements in this collection

• Ext.get() returns Ext.Element object and Ext.select() returns Ext.CompositeElement object.


• All Ext.Element actions can be performed on Ext.CompositeElement object


• The actions performed on DOM nodes can be chained.


• Ext.select() uses the powerful DomQuery class for selecting. See this class for using virtual selectors and more.

Dom scripting

var el1 = Ext.get("my-1st-div");
var el2 = Ext.get("my-2nd-div");

// Appending elements
el1.appendChild("<p>A new paragraph</p>").appendTo(el2) 

// Replcing, removing
var el3 = Ext.get("my-3rd-div");
Ext.get("my-4th-div").replace(el3).insertAfter(el2);

el2.remove()

Ext events

// Binding an event in jQuery 
$(".btn").click(function() {
     // Do something on button click
   });

// Binding an event in Extjs
Ext.select('.btn').on('click', function() {
// Do something on button click
   });

Ext Components

Ajax

// Basic request in jQuery
$.ajax({
   type: "POST",
   url: "myurl.php",
   data: { foo: 'bar' },
   success: function(msg){
     alert( "Data Saved: " + msg );
   }
 });

// Basic request in Ext
Ext.Ajax.request({
   url: 'myurl.php',
   params: { foo: 'bar' },
   success: function(msg){
     alert( "Data Saved: " + msg );
   }
});

// Load Ajax response in directly in jQuery
var msgBox = $('#message');
msgBox.load('myurl.php', {name : $('#name').val()} );

// Load Ajax response in directly in Ext
var msgBox = Ext.get('message');
msg.load({
    url: 'myurl.php',
    params: 'name=' + Ext.get('name').dom.value,
});

Martin Grill at http://arrglarks.de had posted a great tutorial about keyboard navigator with jQuery here.
You can read that tutorial here also :). Thanks Martin Grill for the post :

I had to add functionality for keyboard navigation to my latest project at work recently. It started out with the need to disable the browser’s postback when someone hits ENTER in a formular. Of course more had to be added once our usability guy realized that theoretically eliminates the need for a mouse. The following example is a bit more basic though and covers only what’s need to understand the concepts.

First of all we have to register the event on the document. Unfortunately keypressed isn’t supported on all browsers and keyup is a little too late to prevent all browser functions so we have to go with keydown.

$(document).keydown(function(event){

    var key = event.keyCode || event.which;

    if(event.target.type !== 'textarea'){

        //ENTER
        if (key === 13) {

            //The button has to be visible to be used.
            if ($save.is(':visible')) {
                $save.click();
            } else if ($forward.is(':visible')) {
                $forward.click();
            }

            //Preventing any other action by the browser
            //even if no button is visible
            return false;
        }

        //Not in a textarea or textbox
        if (event.target.type !== 'text') {

            //BACKSPACE
            if (key === 8) {

                //SHIFT is also pressed
                if (event.shiftKey) {
                    if ($forward.is(':visible')) {
                        $forward.click();
                    }
                } else {
                    if ($back.is(':visible')) {
                        $back.click();
                    }
                }

                return false;
            }
        }
    }
});

    BACKSPACE: 8,
