Distributed compilation with Linux C++

I really want to try that feature! I have been using Incredibuild on MS-Windows and it can make a software compile 5 to 6 times faster. (i.e a software normally compiling in 1h compiles in 10 minutes!)

Under Linux some people worked on the C compiler front end to move the process to other machines as required. This is called distcc (i.e instead of using cc to compile, now you use distcc). This front end has a list of all the C compiler machines and uses them whenever possible.)

From what I can see on the front page, the setup should be a breeze (yeah... I know) and it does not even require ...

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 ...

jQuery and hidden IFRAME bug

In the last 3 days I've been working on a new page and ran in some strange problem. There was an error in the console but things seemed to otherwise work just fine so I ignored it (since it wasn't in my own code...)

That error was an unhandled jQuery error which resulted in "let's stop the JavaScript at once." This meant all the page initialization failed (or did not occur.) The code was there otherwise. What give?!

The script in question was loaded from a hidden IFRAME, something like this:

  <div style="display: none;">
    <iframe ...

Updating your Drupal website from FCKeditor to CKEditor

As FCKeditor becomes old and the new CKEditor is started to get there, I'm updating more and more websites to make use of the newer version of CKEditor. This requires a few steps to make sure you don't lose the previous functionality.

Permissions

The update does not transfer the FCKeditor permissions to the CKEditor. This is because by the time you install the new CKEditor, the FCKeditor should already be uninstalled. In other words, those permissions are gone already. Plus, the scheme is slightly different in the new editor.

Roles

The list of roles who are assigned one ...

MS-Access prints white pages

Problem

One of my customers changed a report and all of a sudden was getting an empty page for every other page (it will look like the last page in case you print a single page, but it really is every other page.)

Did you think about the margins?

When you create a report to be printed, you must define its size properly. So if you are printing 8"1/2 x 11" paper, you want to create a report that's exactly (to about 1/100th) the same size.

The total height must be 11" and the total width must be 8"1/2. However, the actual page that you create does NOT include the ...

cellpadding="..." and cellspacing="..." not working

Today I was trying to create a table in a post and just could not get the cell padding I wanted. Without the padding the data is all cramped together which did not look the way I wanted (see Alexis Wilke Accounts.)

I knew I had the following entry in my CSS but did not think it was stronger than the table cellpadding and cellspacing specifications because I thought it worked for me before!

* {
  margin: 0;
  padding: 0;
}

I was wrong, that definition applies to the td with a greater constrained. So I had to add another entry. I solved the problem using a td definition like this:


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,

Assembly Language on MS-Windows and PE / COFF Browser

As I was looking for a COFF Browser today (a tool that would show me the internals of a DLL or EXE file) I stumbled upon a page talking about Assembly Language and the GoAsm tools.

The page is here: [page was removed]

Interestingly enough, he has a link to an advanced assembler called GoAsm. This is specifically for MS-Windows and they do not release the source code of the assembler (at least, not that I can see...) But it is still interesting to see such tool suite around. 8-)

local delete, incoming edit upon update

Today I tried to move an SVN folder to another.

In my first attempt, I tried to copy the folder to a sub-folder that was not in SVN. The result is that the move failed, but nothing seemed to change in the SVN environment.

So I tried again, this time making sure that the destination folder would be an SVN folder.

The second time, however, it failed. The move instruction reported a conflict... Then the svn commit would not work. The SVN system was thinking that I changed something with the first svn mv as the failure did not clear the conflict.

svn mv a tmp/a-1.x        # fails saying tmp/ ...

How to configure alternative soft-links under Ubuntu/Debian

Ubuntu (and Debian) come with many "alternatives".

The system offers many editors, browsers, compilers, shells, etc. Just have a look at the large selection under /etc/alternatives.

ls /etc/alternatives

Under Unix, one can create soft links to soft links to soft links to an actual file. The alternatives work in that way. The soft links defined in the /etc/alternatives folder are pointers that one can change to make his/her system more likeable.

To change one of these alternatives, Ubuntu offers the update-alternatives script. For example, if you don't like Nano, change your
