Docker, an advanced chroot utility

As we are helping various customers we encounter new technologies.

In the old days, we used chroot to create a separate environment where you could have your own installation and prevent the software from within that environment from accessing everything on your computer. This is particularly useful for publicly facing services.

However, chroot is difficult to setup properly. You need to have all the necessary libraries installed, for example.

Docker takes that technology to the next level by hiding all the complicated setup as it takes care of it for you. It will create an environment ...

Best C++ Books

Once in a while someone will ask me which book is best to start learning programming. The fact is that I do not know because I'm already an advanced programmer and it's rather difficult for me to get back to the basics (it feels like a waste of my time, sorry...)

That being said, at Made to Order Software, we've mainly been a C++ shop. We also do a lot of C, PHP, JavaScript and touch many other languages as required by the tasks we perform (bash, cmake, perl, C#, Java, etc.)

That being said, I wanted to underline some of the best C++ books available today. Especially, in the last ...

No more excuses! Protect your passwords on your computer with strong encryption.

More and more, we hear talks about hackers entering personal accounts on systems such as Facebook, Twitter, Instagram and many others. There are many reasons why someone's account will be hacked. One of them is the lack of imagination for their password. Plus, some people use the same password for all of their accounts.

So, if you do it right, you will end up with many passwords. On my end, I have one password per account and that means about 400 passwords... That's totally unmanageable in a fairly standard human brain. For this reason, you end up writing down all your passwords on ...

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. ...

PHP e-Fax requires valid SSL certificates (failed with code 1)

As e-Fax is updating their systems further to be compliant with various security systems, some new problems may arise on your servers.

The main one is an SSL error that is quite unclear.

Warning: stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed in /path-to-php-efax/http_request.php on line 294

As we can see, the error mentions a server certificate function and says it could not verify a certificate.

If your server is not 100% up to date with newest SSL versions or your web ...

DefineEditText

Tag Info
Tag Number: 
37
Tag Type: 
Define
Tag Flash Version: 
4
Brief Description: 

An edit text enables the end users to enter text in a Flash window.

Tag Structure: 
struct swf_defineedittext {
	swf_tag			f_tag;		/* 37 */
	unsigned short		f_edit_id;
	swf_rect		f_rect;
	unsigned		f_edit_has_text : 1;
	unsigned		f_edit_word_wrap : 1;
	unsigned		f_edit_multiline : 1;
	unsigned		f_edit_password : 1;
	unsigned		f_edit_readonly : 1;
	unsigned		f_edit_has_color : 1;
	unsigned		f_edit_has_max_length : 1;
	unsigned		f_edit_has_font : 1;
	if(version >= 6) {
		unsigned		f_edit_reserved : 1;
		unsigned		f_edit_auto_size : 1;
	}
	else {
		unsigned		f_edit_reserved : 2;
	}
	unsigned		f_edit_has_layout : 1;
	unsigned		f_edit_no_select : 1;
	unsigned		f_edit_border : 1;
	unsigned		f_edit_reserved : 1;
	unsigned		f_edit_html : 1;
	unsigned		f_edit_use_outlines : 1;
	if(f_edit_has_font) {
		unsigned short		f_edit_font_id_ref;
		unsigned short		f_edit_font_height;
	}
	if(f_edit_has_color) {
		swf_rgba		f_edit_color;
	}
	if(f_edit_has_max_length) {
		unsigned short		f_edit_max_length;
	}
	if(f_edit_has_layout) {
		unsigned char		f_edit_align;
		unsigned short		f_edit_left_margin;
		unsigned short		f_edit_right_margin;
		signed short		f_edit_indent;
		signed short		f_edit_leading;
	}
	string			f_edit_variable_name;
	if(f_edit_has_text) {
		string			f_edit_initial_text;
	}
};

Additional interactivity has been added in V4.0 of the SWF format. This is given by the use of edit boxes offering the end users a way to enter text as if the SWF movie was in fact an interactive form.

The text is defined in a variable (accessible in action scripts). It can be dynamically assigned and retrieved. It is legal to have an empty string as the variable name (not dynamically accessible).

SetBackgroundColor

Tag Info
Tag Number: 
9
Tag Type: 
Display
Tag Flash Version: 
1
Brief Description: 

Change the background color. Defaults to white if unspecified.

Tag Structure: 
struct swf_setbackgroundcolor {
	swf_tag			f_tag;		/* 9 */
	swf_rgb			f_rgb;
};

This tag is used to specify the background color. It should always be included at the start of every .swf file (after the FileAttributes and Protect tags). Only an RGB color can be used (i.e. there is no alpha channel for that color, whatever the SWF version.)

To create a Flash animation that's transparent (so we can see the website gradient, for example) you use the wmode parameter in the HTML tag with the value "transparent", in which case the background color will be ignored and replaced by a fully transparent background. For example:

<embed width="440"  ...

They are using a Web 2.0 system with PHP running on their server along Apache version 2.x. In other words, they most certainly are running Linux as their server operating system.

And for those who do not know that yet, this is the consortium that takes care of making your browser work.

odbcpp, a simple C++ library to access ODBC

$395.00

Representation of an ODBC Database

 Get a Commercial License 
odbcpp is a strong C++ wrapper for ODBC.

 

The ODBC library is an interesting concept created by Microsoft in 1988. It is a library that wraps the implementation details of database managers inside drivers. And these drivers are accessible from the library.

One of the main problem with accessing any database system, is the large number of possible failures. Handling those ...
