Howto workaround not secured password field alert from Google Chrome 56

Since Google Chrome build 56, password fields will trigger a warning if the page in not secured (read: HTTPS).

If your are a webmaster, you may even have received this kind of alert message from Google like this one :

Unsecure password collection will trigger warning display in Chrome 56 for “your site”

The password field is a specific HTML field type, that will automatically mask the typed in characters, like the one below (yellow background) :

password field hides typed characters

To avoid this warning, the best option is of course to move that page to HTTPS. However, if you cannot migrate the page to HTTPS yet because it is too expensive, or requires too much code changes, or you simply don’t want to implement HTTPS because it’s not worth the effort (nothing important behind this password field), here are 2 tricks to avoid the chrome 56 password warning message.

Howto read an ISO file or mount a virtual CD drive (for free)

Files with the .iso extension are files ready for use with most  burning software in order to create a CD. However, sometimes, you don’t want the whole data inside the CD, just a file, and would like to avoid burning a CD just for that? Here are some solutions.

Open a .iso file like an archive

As the title suggests, we’ll use a sofware able to read ISO file to explore the .iso file content. I’ve currently found the following tools able to read an ISO file:

In both cases, you simply open the ISO file and access it through the embeded  explorer. You may drag/drop files from the ISO file to your hard-disk.

Dirty hack: force primary category for wordpress post permalink

The permalink from Wordpress CODEX

I’m not especially proud of this hack. However, I was getting crazy by how the category used for a post permalink is choosen. And I could not figure out a clean way to control which is the primary permalink (I hope it’s not part of Wordpress 3.0…).

You may need to set the primary category for permalink in two situations:

  • First, you want some consistency among your posts, having them in the same primary category.
  • Second, it’s never fun when, by adding an additional category to an existing post, it changes the post permalink!

Howto Reduce Hard Drive Noise using AAM

hard disk drives

Most of modern hard drives support a function called AAM (Automatic Acoustic Management), often disabled by default. Noise reduction is obtained by reducing the head speed, thus increasing the disk access time. If you prefer silence over performance you might want to enable AAM to decrease the noise level of your hard drive and slightly increase the access time.

Note that access time is about moving the head, not transfering data. So, activating AAM may have no impact to your overall system at all. Highest performance impact reported is around -5%.Thus, for a desktop computer (or notebook), it’s wise to enable AAM. In addition, enabling AAM (and thus reducing head speed) has a good side-effect: reduce the disk power consumption, especially interesting for a laptop.

Choose the best value for AAM by tweaking around the recommended one, depending on the silent level you target. Possible values depend on the drive itself (maybe from zero to 254, or only two states: 128 or 254 for instance).

Wordpress Plugin Google Analytics reset forever

Google Analytics Plugin for Wordpress

The google analytics plugin for wordpress is useful: it allows to insert the google analytics tracking code without any change to the theme file.

There is however something very irritating with this plugin: each time I upgraded the plugin, I had to re-enter the settings. And more frustrating: as long as you don’t update the settings, your stats are not recorded anymore by google analytics. This is why I’m almost not upgrading it anymore :-(

I got an even worst surprise after an upgrade of both worpdress and the google analytics plugin: I was unable to save the parametrs, each try ended with: Read the rest of this entry »

Search files using PHP with a mask pattern

This morning, I cam to a very, very basic need: detect whether a file matching a specific pattern (like ‘*.txt’) is available.

However, I could not find any ready to use PHP function, although PHP5 provides some interesting functions, like scandir().

After completing writting such a function, I decided to share it. So here is it.

Bare in mind it requires PHP5 (or later), as it relies on scandir() and on fnmatch(). Finally, this function while return the filtered directory content, regardless of the content being a file, a link or a directory.

Additional feature: by default, if you call the function more than once in your script in order to scan the same directory, it will read the directory only once: next times, it will use a cached content. To disable caching, set the third parameter to 1.

function searchdir( $path='.', $mask='*', $nocache=0 ){
 static $dir = array();
 if ( !isset($dir[$path]) || $nocache) {
 $dir[$path] = scandir($path);
 foreach ($dir[$path] as $i=>$entry) {
 if ($entry!='.' && $entry!='..' && fnmatch($mask, $entry) ) {
 $sdir[] = $entry;
 if ($nocache)
 return ($sdir);

Did you find this small function useful? Do you have any improvment suggestion?

Wordpress 2.9 is out… Wordpress 2.9.1 around the corner!

Carmen, the 2.9 version of WordPress has launched on December 19th.

You may be tempted to upgrade your blog using the automatic function after discovering the exciting new feature included.

But, wait… There are some flaws in this release. So, you’d better wait for the patch version 2.9.1 (already available as beta).

However, unlike the 2.8.6 release, the 2.9 release is worth considering the upgrade, with new features targetting end-users, like Read the rest of this entry »

5 bootable “tools suits” to upgrade or troubleshoot a computer

I came with a very basic need: copy a Hard Disk Drive to another one. Well, there were some constraints:

  • The HDD is used in a Network Attached Storage (NAS) running Linux, thus data on it are in native Linux format.
  • The source HDD is twice the size of the target HDD, while that actual data volume is of course smaller than the space available on the target HDD.

Trust me, doing this “simple task” turned into a 3 days (and nights) nightmare. The good side of this, is that I (re-) discovered fantastic tools everyone should be aware of. All this “Tools Suits” are a collection of useful tools, compiled over a bootable CD, or even bootable usb stick. My advice: you should select the compilation that better fit your need and make a bootable CD now. The day your computer will stop booting, you’ll thank me ;-) Read the rest of this entry »
