Free Windows Programs To Monitor Your Internet Usage

4 Free Windows Programs To Monitor Your Internet Usage
Here are 4 free programs for your Windows PC to help monitor your Internet usage. This is great for readers who are on a student budget, studying abroad on a limited mobile broadband plan. Those broadband plans normally have a quota that includes both upload and download bandwidths and we’ve tested these 4 programs to see how they fare.

Once you install NetWorx, it will track all your Internet usage with an icon on the taskbar. You can click and launch the program to view usage graphs of each day. What’s good about NetWorx is the ability to set a daily, weekly or monthly quota to track uploads or downloads or both. You can also set the on/off peak usage that some internet providers have and it’ll warn you if you’re about to reach the limit.

Source code

In computing, source code is any collection of computer instructions (possibly with comments) written using some human-readable computer language, usually as text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by a compiler program into low-level machine code understood by the computer. The machine code might then be stored for execution at a later time. Alternatively, an interpreter can be used to analyze and perform the outcomes of the source code program directly on the fly.

Coding conventions

Coding conventions are a set of guidelines for a specific programming language that recommend programming style, practices and methods for each aspect of a piece program written in this language. These conventions usually cover file organization, indentation, comments, declarations, statements, white space, naming conventions, programming practices, programming principles, programming rules of thumb, architectural best practices, etc. These are guidelines for software structural quality. Software programmers are highly recommended to follow these guidelines to help improve the readability of their source code and make software maintenance easier. Coding conventions are only applicable to the human maintainers and peer reviewers of a software project. Conventions may be formalized in a documented set of rules that an entire team or company follows, or may be as informal as the habitual coding practices of an individual. Coding conventions are not enforced by compilers. As a result, not…

R Programming Language

R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.

R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity.

One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor de…

Image Adding and changing styles

Using image styles you can scale, crop, resize, rotate and desaturate images without affecting the original image. By default three sizes are defined: 'thumbnail,' 'medium', and 'large'. The thumbnail style, for example, is shown with the teaser for image posts and when browsing image galleries.

When you change an image style, the module automatically refreshes all created images. Every image style must have a name, which will be used in the URL of the generated images.

To create or change image styles:

Choose Administration > Configuration > Media > Image styles.Add or select a style to edit its settings.When configuring styles you can add effects: crop, scale, resize, rotate, desaturate, and rotate (other contributed modules provide additional effects). For example, by combining effects as crop, scale, and desaturate, you can create square, grayscale thumbnails.Save the settings.
To start using the defined styles they mu…
