Chapter/Section Numbers in Latex: Format

The problem that I had today I had already had in the past but, because I forgot the solution, I was here struggling another two hours or so, so that this blog post is also to help me in case I forget again. I was getting 0.0 as a chapter number. 

To get rid of complications, I used sections instead of chapters when building my pages but I then wanted to use Table of Contents to get a nice index. 

That is how the problem appeared. The solution is quite easy but it takes us a long time to get there on our own.

We have to then add this to the preamble: 

\renewcommand\thesection{\arabic{section}}

\renewcommand\thesection{\arabic{chapter}}

And we then  have to add this to the body: 

\begin{document}

\setcounter{tocdepth}{1}

\setcounter{chapter}{1}

\setcounter{section}{0}

\setcounter{secnumdepth}{1}

Adding Signatures to Your Electronic Letters

If you have a Google or a Yahoo account, it is really easy to add a small chunk of text to better tell others who you are, so say your titles, address, fax and telephone numbers. 

I have just done that in a professional way for the first time, like I had it once but it was more like a marketing token for a few of my products. Now I am telling others who I am and how they can contact me inside of those final lines of my electronic letters. 

It is all free and easy with both Google and Yahoo: All you have to do is right clicking (with your mouse) over the button that means settings, which is a button in the shape of a machine gear. You will then see a menu containing the option settings, which is the option you must choose. With Yahoo, you then click over Accounts and, after that, over the electronic address you have with Yahoo. With Google, you just scroll down up to Signature, when you will then choose adding one. After you clicked over your yahoo address with Yahoo, you have to scroll down up to Signature as well and then tick the box Append instead of Add (Google). Now, you can just type whatever you want to appear at the bottom of your every electronic letter: It is that easy!

You can have Positive Thinking messages there, if you want. You can have reassurance messages. You can even tell people when you will be away. It is a very useful resource that you can use for free and that can make an actual difference in the way you communicate with people, since, once you set it up, you will be able to communicate whatever is in your signature without having to think about it. If it is important, then it is a way of never forgetting to put the information in your letters. 

It is part of what is called Good Business Practice, I reckon.

Add-Ins and the Microsoft Packages

If you are trying to use the Visual Data Manager tab on the Add-Ins tab of the Visual Basic options inside of the Developer tab of Excel, you might be in trouble: If you have the wrong version of MS Excel, the tab might not be available at all. 

The good thing is that you can fix that absence by building the tab yourself. The bad thing is that it will give you a bit of work. You can save hundreds of dollars by building it yourself, however.

Here is an excellent guide: How to Build Add-In

Recording Computer Images for Classes

After a lot of experimentation, I found out that the best technique to record computer images is not using one of the commercial pieces of software that are currently on offer but a digital camera instead, transferring it all to the computer and then reformatting, if necessary. 

Today, I needed to satisfy the demands of Google and upload movies that respected their limits in terms of size, so that I had to grab the resulting recording from my digital camera and use Movie Maker to get the needed reduction. With the second movie, and I am talking about the blog post that precedes this one, I had to convert the image to e-mail format, what made the quality of the item decrease but kept it all inside of the limits in terms of size. 

I now take the computer to be simply another world object, so that we can record what goes in it in the same way we record other things. The evolution of the techniques for building screens and machines now allow us to do this sort of thing. It gives a lot of work and it is very hard to do it if we are on our own but it is feasible and you can see the good results on the previous post, inside of this same blog.

Voice and Powerpoint

You probably have faced the situation of not being happy with the recording you have for your Powerpoint presentation. It is not very easy to find a way out of that.

Basically, Powerpoint creates an icon and gives you the opportunity to give a name to the recording for each slide, so that you can use that resource a bit better than you currently do: Name all recordings in a unique way. Then use the search button from MS (the rectangle that is found to the side of the MS button) to find the file. Click on open file location after right clicking over the name, which will appear at the top of the rectangle that is built over the MS button after you press enter on the search bar. 

You then convert the file, if necessary, or you record the message using the Voice Recorder from your computer. You can even use iTunes to rename the extension of the file, as we have explained here earlier on (will give you a .wav). You then drag the file to inside of Audacity and perform at least these actions: Leveling, Noise Reduction, Equalizer and Normalizer. This sequence, per se, will give you a much better quality of sound. You then must export the file to be able to insert it in your Powerpoint presentation. You will use the resource Insert Audio in this case. 

Audacity is a free program.

Embedding Movies in POWERPOINT Presentations

Ever had problems with it?

Today I faced the ultimate in these regards: I even had a .wmv but THE THING would not cooperate. No, sir: It kept on telling me that the codecs whatever. 

Oh, well, Google comes, Google goes, and I found something of interest that came from the own Microsoft (MS). Shame it did not work as they said it would, so that I went to the page they told me to visit, for third parties' CODECS, and downloaded absolutely everything that seemed to be even remotely related to my problem. After that, I installed everything, even something with the Communist flag on it, with no fear (what we should never do) and... and...: Yes, that's right, FABULOUS OLD NOTHING!

I finally dug to the right side of the Google Universe and found a gem: All, second choice, XP Codec Pack, and, if your problems are of the same type, you should be just fine (the MS message was install codec or Apple product x). 

These guys have all codecs inside of this single batch file, so that you click install and it all works as if you had a Genie.

Free Conversion: Movies

Sometimes you just need to convert .mp4s to .avis, right? The problem is then finding a reliable program through which you can do that. Most of what is available is going to cost you.

I found this website, however, where you can convert all for free and the output is of reasonable quality. It is probably not acceptable for most of what you want to do but if you are going to use the movie in a Power Point presentation, it should be something. 

Convert
