I like Android and BlackBerry. I also like smart consumer electronics. What is “smart”? Well, anything that makes your life easier would be smart… isn’t it?

Enable the Num Lock at startup

This is a very common question I get from my friends. I have no idea why Microsoft didn’t make this easier since they can just add a button to the toolbar. I am aware of the fact that this is probably on several different websites. Having too many well explained documents on this never going to hurt anyone.

There are no security issues of having Num Lock on at startup (at least not that I am aware of). You can do this on computers running any edition of Windows NT, 2000, XP, Vista, 7 and 8. In addition, you can also do this on Windows servers running NT and up. If you are going to do this on your work or school computer, please make sure that you are not breaking any laws. You do need administrative privileges to perform this change.

Using Registry Editor

The easiest way to do this is using what computer geeks called, “regedit” method.

1. Open regedit: I usually type “regedit” in Windows general search (on the start menu) of the computers running Windows Vista and up. This is the easiest way to open Windows Registry Editor.

If you have a older OS, then open Run, and type regedit.exe.

2. Open Keyboard folder: Go to HKEY_USERS\.Default\Control Panel\Keyboard.

3. Edit: Right click on the InitialKeyboardIndicators and choose Edit. It will open the String Edit window.

4. Click OK: and you may be asked to restart your computer. Now you are done!

Using BIOS

The second way of doing this is using BOIS settings. Today there are so many different BOIS software. Therefore it may take few more or less steps to change it from BOIS. What you need to find in your BOIS is the “Keyboard Features” (or sometimes “Keyboard and Mice Features”) and switch the NumLock to ON. I do not recommend using BOIS because it is much safer to do it through regedit. Only if the regedit cannot be accessed for some reason should you be using BOIS to modify the NumLock.

I do not know why the software developers have set this feature to disabled at start up. As far as I know, it will not have adverse effect on your computer.

A Tech Savvy Geologist

I am fortunate enough to find a great summer job at the University of Calgary. I am working for the Geoscience Department cataloging rocks, minerals and other lab materials for a digital database. One thing I notice is that in order for a Geologist to be competitive, these days being “technologically inclined” is a great asset. Not only most of the Geological work is done using software, but even the most basic skills in Geology now being learned by students using technology. While it is not a replacement for hands on experience, the digital media is changing the way we teach Geology forever.

I went to BestBuy and just brought a macro imaging lens for my DSLR, Nikon D80 for taking pictures for the digital database. Along with a great Nikon camera control software, I am hoping that my armature images will turn into a masterpiece collection.

Equipments and Settings

If you want to taker images of minerals and rocks highlighting the cleavage, fracture and small details like that, use a micro lens. The settings ideal for each scenario can varies but in general, placing the selector on Micro mode will brig out the details of the subject.

Never ever save any Geologic photographs in pure JPEG mode. If your camera is a DSLR like my D80, change the file processing settings to high resolution JPEG and RAW. This is like a safety net in case your pictures are not satisfactory, instead of going back to the rock/mineral sample, you can try to edit the RAW file and export it as a new JPEG for publishing. When using image editing software like Photoshop, do not use file size compression. Instead, save the files in the maximum quality, but may reduce the image dimensions to reduce sever load. I found 1200 by 1200 is the best for minerals (close ups) and 900 by 900 is the best for rocks. I also recommend using a CMS (Content Management System; Drupal, WordPress, etc) or a gallery software for server side file compression.

If you have having trouble focusing, try manual focus. If you want to take exclusion of k-feldspar for example, physically get as close to the rock as possible. This will avoid, blurring of the edges of the rock (out of focus). To avoid “shaking” the image, use a tripod. You may want to invest in two different types of tripods; a small scale one and a standard. However, I was able to use a standard.

I use a software to control the camera, which will further reduce the “shake” when taking the image. You could pay for a software developed by the camera manufacture, in this case Nikon or there are many free software available online, so try Googling them!

The identification of minerals and rocks hand samples depend on texture, associations, cleavage, luster and sometimes even colours. Therefore, do your best create images with natural colours. I found sometimes the built-in flash could “tint” the image yellow or white. To avoid this, I had to use better lighting equipments. Changing the angle at which the picture as taken can also effect the colours. Determine the natural colours by examining the samples before you take any images as use it as a guide. It is useless to document a hand sample without proper coulor control.

When publishing your hard work on the web, it is very impotent to add a copyright claim. While I do believe in free education for all, I also strongly support intellectual recognition. Place a copyright on your image using a program like Photoshop (PS). In PS you could create a layer or a “stamp” and simply use it as a template to add copyright to every single image.

Elementary guide to Remote Desktop

I remember when I was a kid; I was having an uphill battle with my Windows machine because the RDC (Remote Desktop Connection) only worked within the internal network. At that time I failed to realized that specific port(s) has (have) to be opened from the LAN (Local Area Network) Continue reading Elementary guide to Remote Desktop

Creating Local Area Networks

Local Area Network (LAN) is a type of data network which is the first electronic network ever created at the early stages of networking. Even today as we are approaching year 2013, LANs still hold their dominance over any other type of network. It is used in almost every home Continue reading Creating Local Area Networks
