Massive Bug in Intel, AMD, ARM and other Processors in Handling VM Memory

In the last few days, we started hearing about a massive bug in the implementation of the VM memory handling.

Intel has been frantically working on fixing host machines kernels in order to prevent one VM from accessing the memory of other VMs that run on the same machine.

Of course, most users are not going to attempt to read someone else memory so in that sense, most of us are relatively safe. But all of those who are not so lucky and have uninvited guests on their systems are running at very high risk. The information available from Intel says the memory is accessible only in Read mode. ...

CSS3 media queries

CSS is improving with the introduction of CSS3.

Contrary to the previous version, CSS3 supports selections that are very advanced, offering capabilities close to what you could write in JavaScript.

Today I wanted to talk about the Media Queries because that can be used to very much optimize the list of links used to load your CSS data.

In HTML, you can use a <link ...> to add a CSS file to your page.

<link rel="stylesheet" type="text/css" href="style.css" />

In this case, the file style.css will always be loaded, whatever the media being used.

Upgrade to PHP 5.3.3 or newer because of security issue

If you are responsible for a Debian or Ubuntu server and run PHP on it, make sure to run the following command to fix several security issues found in PHP:

sudo apt-get install php5-suhosin

This will make the necessary and your PHP version (security wise) will look like you have PHP 5.3.3.

What I found quite annoying in regard to this issue is the fact that it was very difficult to find a mention of this upgrade. All I could find in large number were people saying that you'd have to get an upgrade using the source code of PHP. Somehow, I did not feel like upgrading PHP from ...

Table of Contents Settings

Filter Configuration

At this point, most of the Table of Contents configuration is done in the Table of Contents filter.

This means multiple Input formats allow you to make use of several different configurations.

Import

Tag Info
Tag Number: 
57
Tag Type: 
Define
Tag Flash Version: 
5
Brief Description: 

Imports a list of definitions that are to be loaded from another movie. You can retrieve objects that were exported in the specified movie. You can have as many import as you like, though you should really only have one per referenced movie.

Tag Structure: 
struct swf_import {
	swf_tag			f_tag;		/* 57 or 71  */
	string			f_url;
	if(version >= 8) {
		unsigned char		f_version;	/* must be set to 1 */
		unsigned char		f_reserved;
	}
	unsigned short		f_count;
	swf_external		f_symbol[f_count];
};

WARNING: in a Version 8 movie you MUST use an Import2 tag instead of Import or it just will not work (Import tags are ignored in version 8 movies).

Appendix A — The geometry in SWF — Matrix

The coordinates are often transformed with the use of a matrix. The matrix is similar to a transformation matrix in Postscript. It includes a set of scaling factors, rotation angles and translations.

When only the scaling factors are used (no rotation) then these are ratios as one would expect. If a rotation is also applied, then the scaling ratios will be affected accordingly.

A filter defines how to transform the objects it is attached to. The first byte is the filter type. The data following depend on the type. Because each filter is much different, they are defined in separate structures. You can attach a filter to an object using an ActionScript or the PlaceObject3 tag.

The following describes the different filters available since version 8.
