My Embedded YouTube Video Disappeared

Embedded videos from used to work just fine on my website.

Today, though, I just noticed that my video was not showing up on one of my pages. Looking into it, I found out that the problem was the protocol.

I'm not too sure whether it was my browser or YouTube,com (although I'm not too sure how would know...) but the fact is that the iframe source was using HTTP and the page I was viewing used HTTPS.

By editing the page and changing the video from HTTP to HTTPS resolved the issue. It is generally much better to always use encryption anyway.

SugarCRM Community Edition for Ubuntu 16.04 with PHP 7

As I wanted to use SugarCRM on my new server, I looked into the Community Edition and apparently the company is not willing to convert their code so it works under PHP 7.

So that would not work on a newer system because the code uses quite a few forbidden mechanism (wrong class definitions, old defunct functions...) and that prevents to even instal the system on your machine.

Now, I have looked closer into it and I am getting a version that works pretty darn well already. I still have some issues here and there, but I think you can already make use of that version. Except for one thing which ...

Boot into the command line console in Ubuntu 16.04

As I just upgraded my 14.04 installation to 16.04, it booted right up to lightdm.

I had it properly setup to boot in a console before, but somehow it changed the behavior on me.

This is because the computer is now using systemd to boot.

I already had the GRUB variables setup as expected:


But this is not enough if you want to start in the console when running systemd (which is running since 15.04).

systemd has a list of variables you can tweak using the systemctl command. To boot in ...

Bad move for PHP unpack()! So unpack() stopped working?

Today I noticed many errors on one of my websites. Looking closer into it, I noticed that the code for the mo_references Drupal module stopped working.

It took me some time, especially because the code seemed to work just fine as all the files could easily be displayed.

Actually, that was not the case. The unpack() character 'a', which I used, was transformed from a simple string that gets trimmed, to all the characters, including the NULL characters. Ouch! Now we have to use the 'Z' character instead.

I use it to unpack() a tar file by loading 512 bytes of data in a ...

My JavaScript code does not get the correct widget size, why?

As I am developing a set of pages for a customer, I ran in an intersting problem: my JavaScript function could not properly define the sizes of a box.

That box is heavily tweaked with the CSS assigned to it, as well as all of its neighbors. So I thought that may have something to do with it.

What I hadn't realized so far is that the ready() function of jQuery() is called once the script that includes it is ready (as in loaded) and not once the document as a whole is ready (done loading, i.e. onload event.)

With that knowledge it was easy to understand that I was actually finding myself ...

Postfix says it does not allow relaying?!

As we are upgrading our server to jump from version 12.04 to 13.04, we encounter a few problems.

Two with Postfix, first the Postgrey port has changed. It was 60000 before, now it is 10023. Don't ask me... Anyway, that was the easy one.

The other problem was a relay error. I could send emails all I wanted, but not my partner who does not show his server as part of our Made to Order Software Corp. network. Relay is why a computer allows emails from server X to be sent to server Y through server Z. You are server Z, that's the relay.

The fact is that if you can log in your account on ...

MS-Access: Application-defined or object defined error

Today I got this weird error: Application-defined or object defined error.

Looking into it, I could not find the right answer.

The failing code was in a sub-form and when called it generated the error immediately. The code I wrote was:


And of course, in the parent I had the NewSelection function defined:

Private Sub NewSelection
End Sub

The DoSomething would update a button as required...

For real MS-Access pros, you may already have noticed what the problem was. What's really annoying is that the error we get is not capable of telling ...

Upgrade from Ubuntu 9.10 to 10.04

Today I did an upgrade of a server from 9.10 to 10.04. We were on a server version before upgrading to 9.10 but we could not directly upgrade to 10.04 (working upgrade paths are very specific; see a list here: )

The most surprising part was the python script at the end.

  /usr/bin/python /tmp/unique-folder/lucid --mode=server --frontend=DistUpgradeViewText

The command line itself is not specifically strange. However, the behavior at the end of the script is a bit strange, mainly because I hadn't see it before. Last time the upgrade was

QtTest and "Cannot create a QWidget when no GUI is being used"


I have to use Qt these days. It's a good system, but there are a few tricks to know about.

As I was starting to write a test, the test needed a lot of numbers but nothing much otherwise. So I decided to limit the #include to a minimum by deleting all of those that I did not need.

The result was this error:

"Cannot create a QWidget when no GUI is being used"

I looked into it and sure enough people talking about it say: Well... where is your GUI?

Great, but I don't see how that helps me in fixing the problem, does it do it for you? Neither?!



Deleting a database in Synergration

Synergration AccessBooksRT is a tool we use to get a copy of QuickBooks tables in an MS-Access database.

It works great for our purpose and transformed some super sluggish forms into lightning fast forms. We still use QODBC for some of the work (updates) but 99% now goes through the database generated by Synergration instead.

  • cvs

    CVS is a control source tool that has been used for a quite long time. It uses RCS as its bottom layer (RCS is limited to a single computer environment.) Each time the source code is checked in with a diff so one can always retrieve a previous version. CVS is often being replaced with SVN.

  • dump

    The dump command, under a Unix system, is used to dump the entire file system to another device. By default, the dump output device is a tape device (/dev/tape). Now a day, however, it is often used with other devices such as another file system (from one hard drive to another.)

    Other systems use that same keyword. It is particularly the case of database systems. For instance, the PostgreSQL database has a pg_dump command.

    The opposite command is restore. That command is used to get the data from the output device and put it back on your hard drive.
