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 ...

HP Printer options not offering "Color: Off" option anymore

As I upgraded to Ubuntu 13.10, I noticed that I lost the option to turn off the color when printing.

Looking around all the available options, no one to make it black and white (although the old option was saying something like: Color: Off; it was somewhat weird.)

Now that option is completely gone. There is no way for me to turn off my HP Printer color when I am in Acrobate or LibreOffice. I searched on the Internet to see whether that was just HP trying to get you to use colors on your printer or whether the option was available... somewhere else.

Indeed, I had to go to the System ...

New Ubuntu Desktop: Unity How To

I love Linux and use Ubuntu, but all of a sudden you don't have support for Gnome. Instead they now force you to use Unity. It's probably a good idea to go with the flow because trying to maintain Gnome is probably a hell of a lot of work so...

I have to have a few things in my window system:

1) Menus MUST be attached to the window I'm using. I don't like the Macintosh way. Sorry. To remove the menus from the top, run the following command:

sudo apt-get remove appmenu-gtk appmenu-gtk3 appmenu-qt

jQuery and functions/variables between a parent and an IFRAME

In the last few days I have been working on a small project to get a really nice form for one of my sites. The form uses a lot of JavaScript for all sorts of fancy things (such as check user input to make sure we don't accept total crap such as an empty entry or just "1" as a credit card number.)

The information finds itself in an IFRAME, which was the easiest way to get the time to load at decent speed and  to better manage the form in a separate area and not the main landing page. This will make it easier to maintain the landing page itself.

however, that created ...

Setting up an array of JavaScript functions in jQuery

Today I worked a bit with jQuery to create an advanced form. Advanced just because it is tabbed and appears in a pop-up, nothing too major really. Maybe later I'll add some tests to validate the data being entered before someone can submit the form...

In any event, I ran in a problem which was to create a set of click callback functions (event handlers) and each of which should make use of a different index. So... I have 4 tabs and each one has a number: 1, 2, 3, and 4.

Say I call each one of these numbers #tab1, #tab2, #tab3, and #tab4. Now I want to create a click function on each one ...

Multi-level lists in MS-Word... The new way!?

Okay, it has been a little while now, but each time I just have to search forever to find out how to create a multi-level numbering list.

By default, a list will appear as this:

1. Chapter

    1. Section

        1. Sub-Section

Which may work for you, but in many cases you want to have all the list numbers appearing in your section and sub-sections as in:

1. Chapter

    1.1 Section

        1.1.1 Sub-Section

Okay, so that in itself it actually very easy, but it used to be that you could ...

Qt and DLL mismatch / error

My Story

I'm using Qt under Linux and MS-Windows.

When I started with MS-Windows, I could not run the Release version. I thought the problem was because I was using a pre-compiled version of Qt 4.6.x and let it go for a while.

At some point, I finally upgraded to Qt 4.7.x thinking that would clear off that Release problem.

This time around, I actually compiled the library, see instructions here:

  Compile Qt 4.7.x with Visual Studio 10 (VC++ 2010)

The result was that a few bugs I noticed while running with 4.6.x were gone. Nice. However, I still couldn't run with the release version. Why would that be?

Restore Firefox warnings when viewing non-secure data on a secure page

One thing that I quickly do on my browsers is turn off warnings about non-secure data when browsing secure pages (with HTTPS .)

It's rarely a problem and with all those features you like to have (Facebook, Twitter, AddThis, ShareThis, Google Plus, and othe fun widgets...) it's hard to avoid. Actually, many times the problem lies in one of these scripts and thus you cannot just fix your website. Without that 3rd party script owner fixing their code, it just won't work at all.

Now, once in a while I work on a customer website and they really want to have a 100% clean slate. Thus,

.change() not working right in Internet Explorer

I had a problem with jQuery and was wondering what could be wrong. Looking around for a solution, it was clear that Internet Explorer is the problem. Not the other way around (As usual.) The thing is that the function works, just not in realtime.

So... I have a Terms and Conditions flag, when you click it, I want to enable the Submit button in the form (by default the button is disabled.)

So I have a function something like this:

var valid = function check_valid() {
  // compute valid
  var valid = ...;
  // assume valid === true if button should be enabled
  ...

C printf(3) for int, long and long long that works every time

Of Note: This only applies to C99, not C++.

I learned something quite interesting today and wanted to keep a note of it.

Whenever I use a printf() with a format such as %ld and try to compile my code on "many" different platforms, I often get warnings on another one.

The fact is that an int, a long, a long long, an int32_t, int64_t all use a different combination depending on your platform and whether you're running in 32 or 64 bit.

So, the answer to this problem are the #define found in the inttypes.h header file:

PRId8
PRId16
PRId32
PRId64
