How to comment and uncomment blocks of code in the Office VBA Editor

Good to know.

http://stackoverflow.com/questions/12933279/how-to-comment-and-uncomment-blocks-of-code-in-the-office-vba-editor

One way to quickly comment and uncomment blocks of code is to add the Comment Block and Uncomment Block buttons to your toolbar.

Go to: View -> Toolbars -> Customize

Next, go to the Commands tab and then the Edit category:

Select the Comment Block and drag to the toolbar:

Do the same for the Uncomment Block.

Change Default Font and Size for Text Boxes in Excel 2010

I had someone ask me if I knew how to change the default text font and size for inserting a text box.  Of course it wasn't too straightforward, but with a little Googling I was able to find this!

http://answers.microsoft.com/en-us/office/forum/office_2007-excel/textbox-bug-all-excel-versions-setting-new-default/8bfabf2d-eceb-4f8e-959d-b03e54d0e10a


Here is one way to change the default font. It does not allow to you to change the default size!

No it's by design rather than a bug. Unfortunately when you copy and paste within a text box, Excel by default formats the pasted text using 'body font' from the Fonts Theme set for the workbook, and the standard font size that is set in Excel options, rather than keeping the format of the source, which is annoying. Calibri is body font in the default built-in Fonts theme called 'Office'. The easist way to change this behaviour, assuming you only want all text boxes to use Arial, is to create a special theme with the font you want. Do this from the Page Layout ribbon, select Fonts under Themes, and 'Create New Theme Fonts'. Edit the Body font, then name and save the Theme. Now select any of text box and apply the customised Font theme. The font in all text boxes should adjust to the theme font. Copying and pasting within the text boxes will also use this font. In regard to the font size, this is based on the default font size set in Excel Options. If you want to use this customised theme for all new workbooks, then you can create a customised template with the your customised theme pre-selected: Open a blank workbook, apply your custom Fonts theme and then save is as a template called Book.xltx, in your XLStart folder: Save As, Select Save As Type - Excel Template (*.xltx) type, change the name to Book, and locate it in the XLStart folder. In my PC (Vista) this is:C:\Users\UserName\AppData\Roaming\Microsoft\Excel\XLSTART\ All new workbooks created will then be based on this template.

This is the trick you must use to change both! You simply create an initial text box the with the font and size you wish. Then right-click on the text box and choose the "Set as Default Text Box." This should allow future text boxes to be set to this new default. Found it here from this nice instructional video on YouTube!!

How to update date and time in header footer in PowerPoint 2010

Ok, so this may be stupid, but since Microsoft products are used heavily in my new work environment, I "have" to (well I don't have to, but I want to) learn shortcuts and things such as overlay modifiers, for example, what I am posting now, in how to update a date amongst slides.

So, I have been given a PowerPoint for internal weekly progress reports.  The PowerPoint had a master slide which I am familiar with since I did use PP for school presentations.  I tried to change the date on "the" master slide.  However, this did not update the date for all slides.  I tried to Google and look up a way to update a date/time insert.  All I found were how to simply insert the date or insert/change the date for headers/footers.  I was "unaware" that the date was inserted on the slides as a footer, and I was thinking I could insert a text box with some type of "code" for the date which would update automatically when changed.  At any rate, I was simply thinking about it too much and in a roundabout way.  I simply just needed to go to the Insert tab then Header and Footer.  There you can change the date and its format and then apply to all slides!  Stupid and small, but I have to become more efficient in other things other than just LaTeX.  I will be heavily involved with Microsoft products, such as Excel and PP.  Not that I was ever against using them, I'd just prefer other software.

This is a pretty neat little app.  If you don't have MathType and or don't want to use equation editor for Microsoft products (or similar), such as PowerPoint, then this is a nice way to display equations through an image.

Free PDF cropper!

http://www.pdfscissors.com/

Pretty cool app!

Features:
No installation required. Just click the start button,
Take those extra margins aways with easy cropping tool!
Drop margins from all pages by drawing just one crop area!
Avoid accidentally cropping some texts
See all pages together in stacked view
Scanned book? Crop odd/even pages separately
Complex pdf? Crop individual pages separately with full freedom.
Create crop areas easily
Draw, resize, move crop areas
Copy / paste crop areas using usual Ctrl +C / Ctrl + V
Why:
I myself faced a lot of difficulties to read pdf in kindle (and mobile phones / internet tablets), specially the image based pdfs (scanned image pdfs). Got tired of zooming and scrolling while reading a nice book. So created this to help me 'dive into the reading'. I hope it helps you too.

Why free? Well, I like programming and I needed the tool, so I would have created it anyways :P
To run the app, just click those buttons on the left
Those will launch the app directly...
no hassle
It will use 'Java webstart' technology. You need to have latest Java in your computer.
The app does not modify the original pdf, it creates a new pdf with the new crop areas that you will draw.
If you run the offline version, it will create a shortcut on desktop (and also to programs menu on windows). You can use that to run the app without internet connection.
If you have internet connection, app will keep itself automatically updated, no need to worry about getting the latest version.
NOTE: The app does NOT upload any file / any data from user's computer, the pdfs are cropped on user's machine.
Another note: App may ask to connect to Google sites, don't worry, it does that only to check whether there is any updated version of the app. It's an open source app and I have no intent to collect any user data.

Why doesn't Chromium have “Chrome PDF Viewer” plugin?

This is a nice way to get the PDF viewer to work in Chromium.  Essentially, you take the "command" from Chrome and link it, or copy it, to Chromium.

Another site for Ubuntu

Whelp, it's been awhile since I've messed with Ubuntu (and this blog!).  I just upgraded from 11.01/12.04 to 13.04 so I think I missed most of 12.04, all of 12.10, and 13.04 (with another release right around the corner, 13.10 in October).  Was using a Windoze laptop and desktop for school.  My desktop has been down for the count with a power issue for a long time, and I haven't had the time to mess with it.  I turned in my school laptop so I had to revert back to this laptop.  This Ubuntu is partially broken, but works for the most part.  I've got a Surface Pro from school to use as well.  Not real impressed with is so far, but it's decent for lightweight Windows usage compared to a traditional laptop.

Anyways, I thought I'd post another Ubuntu website which I thought might be helpful.

It's called n00bs on Ubuntu

LaTeX Tips: Displayed Math - adding sections, subsections, etc. to equation numbers

LaTeX Tips: Displayed Math

How to number equations. By default, LaTeX will number equations consecutively, as (1), (2), etc., assuming you use the automatic equation numbering mechanism. If the paper is very short, or if there are only a few numbered equations, this is fine, but once the numbers get into the twenties and higher, a scheme that numbers equations by section, as in (1.1), (1.2), ..., (2.1), etc., is preferable. In fact, for the vast majority of journal articles, the latter is probably the best numbering scheme. To get equations numbered by section, just put the following into the preamble: " \numberwithin{equation}{section} ". For books, theses, or very long papers, an equation numbering scheme that is three levels deep (with numbers like (4.1.1), etc.) may be appropriate. To get this, just replace "section" above by "subsection", or the corresponding innermost level. The same mechanism works for other counters, e.g., theorem counters, instead of "equation".

If you have a thesis or some other class/document type it may be different.  In my case (UTK thesis/diss class) it automatically numbered 3.1 for chapters.  So for "3.1.1" it was "section," and "3.1.1.1" I used "subsection."
