My NVG 510 broadband light is blinking red

Somehow my NVG 510 broadband light started blinking red a couple of time in the last few days. I've been wondering why and I think I have the answer now.

In most cases it may just be that the broadband signal disappears for too long and the modem disconnects.

However, in my case, I think it was because they made an upgrade (a push!) on the modem because a few things do not work as expected anymore. (i.e. I cannot access the nsh shell anymore...)

Whenever software is upgraded, the likelyhood that you have to reset the whole thing is very high. I had to restart twice and even after that, ...

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 ...

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 ...

MS-Access hangs when setting a recordset

Today I experienced a hard lock-up with MS-Access as I was in a form typing a new query.

The new query data is checked first, if valid, then the query is processed and ends in a SELECT SQL order which I save in the Form with a simple OpenRecordset call as in:

sql = "SELECT stuff FROM thing WHERE foo LIKE 'begin*'"
Set CUSTOMER_LIST.Form.Recordset = CurrentDb.OpenRecordset(sql)

That used to work just fine in older versions of MS-Access, but we now use MS-Access 2007.

The hanging happens on the 2nd line, when the Set occurs. Note that it generally happens the second

Compiling in 64bit with VC 2010 can result in a crashing software

Today, as I was trying to run a 64 bit application in Release mode under Windows 7, I got a crash about a NULL pointer. There is the debuggee (<- well known Microsoft spelling of Debugger) error window:

Unhandled exception in ... Access violation reading location 0x0000...

Unhandled exception at 0x52740ccf in guikeyboard_test_developer.exe:
0xC0000005: Access violation reading location 0x0000000000000000.

So... according to this error, the software access a NULL pointer. It took me some time, but the problem was not a NULL pointer, it was an unaligned memory access. In other words, it is trying to write a a pointer that is not 16 bytes aligned, which is ...

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,

There are some forms where Drupal '#size' does not seem to work, why?!

I created a form a while back and included an entry like this:

  '#size' => 10

in several text fields of the form. Especially useful when you add a suffix:

  '#field_suffix' => 'Something'

But that would not do anything... I looked at the output of the form and it looked 100% correct. In other words, the input tag had its size="10" properly set. So the next step was to find whether some CSS code would be in the way.

You bet! The node.css file includes the following:

PHP CLI Segmentation Fault with pgsql

Somehow, whenever I tried PHP CLI, it would crash because of PostgreSQL. (i.e. if I use the database in PHP through Apache, no problem, but the same script run via the command line, and it crashes on exit, no matter what I do with the resource handle.)

I was puzzled and did not really know what to do, but some people have found the solution. Now, what is really surprising is the fact that it has been around for ages and not yet fixed in the system.

The fact is, it does not matter too much as long as there is a work around, but you need to apply it yourself...

Negative constant ... was passed to a negative sink

Today, as I was working with Coverity, I got this one message...

Negative constant passed to a negative sink.

Although I understood the meaning, I thought that this message was very confusing, How about:

Unexpected negative value in parameter #<position>

AddThis weird behaviors

I just switched my websites from one server to another and noticed that on my main company site (http://www.m2osw.com) I would get a # at the end of the URL. Automatically added somehow. Thinking that could be a bad guy I checked the code and could not really see anything.

Hitting "Back" once, I noticed that the # would be transformed to #atssh-digg. I don't have anything specific about digg on that page except the AddThis button. That adds Digg among some 150 different systems where you can share my pages.
