Twitter and emails

Today, I finally registered with Twitter. I'll be looking into a way to connect that to my blogs so each time I blog, I get a tweat eliminating the need for me to actually tweat for real.

Okay, that's fine, but guess what... they want me to verify my email address and it does not work.

reCATPCHA for Drupal

It took me a little time, but I finally search and found the reCAPTCHA.

The default CAPTCHA for Drupal looks awful. It is called Image and creates very ugly extremly hard to read images. So I always wanted to switch to reCAPTCHA that is not perfect but looks a lot better and has audio availbale.

So today I found it, it is here: http://drupal.org/project/recaptcha

Note that you still need the CAPTCHA system, it just adds one more option which is reCAPTCHA instead of Image. (at leat, that the way I use it.)

List Open Files

This is a quick note so I can find the command I need to use to list open files.

My search will work this time.

lsof stands exactly for "LiSt Open Files"

That gives you a list of all the files opened by your system, process by process. It can be useful to know if you are developing a program or if you are limited in the number of files opened at once.

wput, a really bad tool?

The other day, I setup a small script to send file on an FTP. That was a long time since I had done anything like that and was not really thrilled, but I'm working for a client.

The FTP worked pretty well. The upload was going for a while. According to wput, if the connection is lost, it automatically retries and continues the transfer. It got stuck 3 times on me. For hours. No retry. Zilch.

Now, I updated my files on my end and then started the transfer again. Had to wait forever, although that is not the direct fault of wput, when it gets stuck mid-way, it's bad.

MO Paragraph trimmer filter test page

This page has empty paragraphs at the top (before this line), at the bottom and in between each paragraphs. In a way, this is a weird module!

It use the MO Paragraph trimmer filter1, written in PHP for Drupal 6.x, to remove all of those empty paragraphs. Sadly, there isn't a good way for you to check the page source, but you can test by posting a comment (I think...)

MS-Access: INSERT INTO syntax error

Today I was creating a report and created a table with a column named 'Group'. It looked like it worked just fine so I moved on with it.

Then, at the point I wanted to insert data with a simple INSERT INTO ... statement, it broke. The statement would generate a syntax error. Yes. The simple answer is that GROUP is viewed as a keyword and thus when used as a field name it needs to be escaped (i.e. written between backward quotes: `...`). Not liking the need to escape a field name each time I use it, I just renamed the field which is even better.

I put that radio button in the wrong Option Group, MS-Access

It happens all the time. You create two or three option groups and start adding radio buttons.

Then you write some VBA code attached to each button and/or their option group.

And at some point in the development you notice that one was put in the wrong option group.

Just deleting the option and creating a new one is not a good option because then you have to make totally sure you have the right setup and that can take some time to review.

Instead, you can move a radio button from one option group to another by following these steps:

No AfterUpdate event on Check Boxes in MS-Access?!

Symptoms

  1. My checkbox does not have an AfterUpdate event
  2. When running, I cannot de-select that check box once selected

Discovery Process to Solution

In MS-Access, you often want to run an action after the user changed something in a form.

at job spool growing

How it works

The at command is often used to start a process at a later time. It can run any script at a specified date and time.

For instance, if you want the computer to send you a signal in one hour, use something like:

cat signal | at -q z now + 60 minutes

Assuming that the file named signal contains the commands necessary to generate the signal. Then in 60 minutes, the script will be execute and the signal will be heard or shown.

Connections to clamav.inoc.net, why is that?

Lately, I noticed that I always had a clamav.inoc.net connection. I was wondering why... I did install clamav but I did not recall changing anything in Apache where I'd get requests from the outside that would look like clamav.

The fact is I also installed freshclam. By default, that gives you a line like this in your netstat -a64 listing:

    tcp   383     0 halk:38272       clamav.inoc.net:www     CLOSE_WAIT

Most of the time you won't catch it when it is still connected and sending/receiving data. The deamon that accepts the connections is freshclam and it will save the new data ...

    Giga bytes--these days, the common measure for memory and disk space. It changed in the last 20 years from Kb (Kilo bytes) to Mb (Mega bytes) and to Gb. With disks, we are close to Tb (Tera bytes) and some people talk about Pb (Peta bytes).
