### Page list for MS-Windows

• For a week now I have had a warning when shutting down saying that there was yet another update to install on shutdown...

I did not really check on it for that long, but today I decided to check the auto-update as I was running the computer. There was the installation ready to be run. So I clicked on the button to start the installation.

After a moment, the installation process stopped with a really weird error:

Error message: Code 13EC, it's an unknown error.

It's funny that any programmer would create an error that the computer cannot figure out... Way beyond me.

This being ...

### My Boring Story

Microsoft Office is making progress... or... is that really progress?!

I got a great little surprised when I met face to face with Access 2007 and all the menus were gone. I wasn't warned about that one! Not only are they gone, you MUST use little tiny icons in the place of menus so it takes you an awful long time to learn the icons, but not just that, YOU have to choose which icons will appear on your toolbar.

• The mouse pad worked just fine for days and "all of a sudden" my Acer, an Aquire R 14 (Acer Touch R3-471T), but it looks like many if not most Acers have the same issue.

The fact is that I use the Fn + F8 key to mute the speaker all the time, whenever there is an ad in a video, I really have to do that!

The Fn + F7, which is right next to the Fn + F8, is actually a key one can use to turn the Mouse Pad ON and OFF. Do it once again, Fn + F7, and the Mouse Pad will work again.

Hopefully you had a USB mouse or like me, you installed Synergy and thus could use your Linux mouse anyway. ...

• 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.

• ## Error about a local certificate?!

The other day, I got a new certificate from godaddy.com. I installed the certificate by replacing the files and simply restarting Apache. I then checked in Sea Monkey and it worked great. Checking the certificate it told me "valid for another 3 years."

A few days later I got an error from eFax saying that our certificate could not be verified. Weird... I tried with wget and got the error! Hmmm... I tried again with SeaMonkey, just fine. Then I tried with FireFox, error too! The error with wget is like this:

ERROR: Certificate verification ...
• As I was working on a new Report, I had two fields with computations.

These are easy to handle, for example, for a Total you write something like this:

=[Quantity]*[Price]

And you get a product of the quantity and the price.

That works great. At first I had a very simple query and it looked like there was a problem in computed field, but I still decided to first add the WHERE clause to allow the user to limit the data to a given set of dates:

WHERE (((Invoice.CreatedDate)>=[Enter start date:])
AND ((Invoice.CreatedDate)<=[Enter end date:]))

Notice all the parenthesis. Also ...

• 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-)

• ### Problem: Associate, easy! De-associate... but how?!

The association of a label with another widget is easy to obtain. You want to do that especially if you want to hide the widget or apply some similar effects to it so both, the widget and its label are affected. This is especially true if you hide the widget.

• In MS-Access, you can select a special value for your combo boxes called:

"Find a record on my form based on the value I selected in my combo box"

In older versions of MS-Access, all you had to do is select the option and be done with it. However, the option would have no effect if the form was not properly assigned a source query.

In order to paliate to that problem, Microsoft decided to check the current form status and, if unlinked, hide the option altogether so you cannot make a mistake.

The problem is that for many people the train of thought was not automatically that way.

All software make use of numbers. Everything is a number. The most basic number in a computer is 0 or 1. This is called a bit. These are represented with electricity. Although in most cases we see it as 0 - Ground and 1 - Voltage (i.e. 1 volt), the bit representation in software and in hardware may be interpreted either way (i.e. a 0 could mean that the voltage is 1V and not 0V.)

Combining these zeroes and ones we offer end users to handle much larger numbers. With 8 bits, you can have numbers from 0 to 255 (unsigned) or -128 to +127 (signed.) Now a day, computers can handle a much larger number of bits in one cycle. Most processors use 64 bits but they can calculate numbers on 128, 256, and for some 1024 bits at once. Also with parallelism, the size can be viewed as even larger (i.e. handling a 64 bit number in 1,536 threads like on my old nVidra Quadro 600 is equivalent to one large number of 98,304 bits! That would be 2 power 98,304 possibilitie or about 2.8359e+29592 in decimal.)

Integers are easy to handle. Although when working on math problems you generally see the set of avaialble numbers as equivalent to N although mathematicians know that computers can really only handle a limited set of numbers. For example, on a 64 bit computer, the usual range is -9223372036854775808 to 9223372036854775807, This is generally enough although at times some equations have to be reworked to avoid really large or small intermediate numbers that work fine in math equations, but not so well on computers.

Now, math also includes other sets of numbers such as D, R, and C. Computers do not offer any way to represent numbers in R or C but they can offer D to some extend. These numbers are called floating point numbers because we do math using an exponent. The exponent makes the decimal point "float" in any location as the number used for the exponent offers. Using a 64 bit floating point, you can have positive and negative numbers with precision varing betwee 10-308 and 10+308. This includes a positive zero (+0) and a negative zero (-0), which is import in a few cases (although +0 = -0 is true, you can get the sign of a number and distinguish both zeroes). Note that at first decimal numbers were going to also have a positive and negative zero, but it was instead decided to have one more negative number (remember, with 8 bits we have signed numbers from -128 to +127, this is because in the positive numbers we have a 0 which we don't have in the negative numbers.)
