Simple explanation of Naive Bayes classifier

Probably you’ve heard about Naive Bayes classifier, and likely used in some GUI-based classifiers like WEKA package. This is a number one algorithm used to see the initial results of classification. Sometimes surprisingly, it outperforms the other models with speed, accuracy and simplicity. Lets see how this algorithm looks and what does it do. As you may know algorithm works on Bayes theorem of probability, which allows to prediction the class of unknown data sets. Hoe you are comfortable with probability math – at least some basics.

What does studying to be a software developer involve?

If you have ever wanted to embark on a career as a software developer then you probably want to know what you need to study in order to make that happen. You want to be able to give yourself the best opportunity of securing the job you want. The good news is that you can study to be a software developer even if you are already working full time; all you have to do is enlist on an online course. We are going to take a look at what tasks you can expect to undertake if you become a software developer and what subjects you will study in order to prepare you for these tasks.

Refreshing your computer gear

The computer is probably number one place where we spend the most time. We usually use it for many things, including work, study, playing games, watching movies, and socializing with friends. It is essential to keep PC workplace comfortable and attractive. The computer itself needs refreshing from time to time. When it is still relatively new, I mean up to few years old; you may want to upgrade some parts like HDD, RAM, and Video card. They can revive PC to new performance level, but if you are looking for a more drastic change in performance, then you should think about getting new PC. But in most cases, simple upgrade gives a better feeling. Simple replacement of the magnetic hard drive with SSD will give you noticeable improvement. I think this step should be first on your list. You will get much faster boot time, faster loading applications, and quieter work. SSD, in my opinion, is also more reliable because there are no mechanical moving parts that can fail.

Example of enumeration c in microcontroller programming

Enumeration allows defining a user data types in C language. For this purpose, a #define pre-processor is used, which allows for describing a set of constants. They allow reading and understanding program code much easier as you may define human readable types. For instance, using pre-processor we can define a simple numbers to be as follows: Define is a powerful tool for doing many different definitions in pre-processing stage of source code, but in C language, there is an alternative way of defining a user data types – enumerating using keyword enum: By default, enumeration assigns values from zero and up. You can use enumeration of new types as in following example: Also, you can use an enum to assign special characters to meaningful words like this: enum escapes { BELL = ‘\a’, BACKSPACE = ‘\b’, HTAB = ‘\t’,RETURN = ‘\r’, NEWLINE = ‘\n’, VTAB = ‘\v’ };or enum boolean { FALSE = 0, TRUE }; An advantage of enum over #define is that it has scope, which means that the variable (just like any other) is only visible within the block it was declared. Example:

Handy portable electric drill for hobby projects

Lots of hobby projects involve drilling, screwing, and repairing. In many cases, a power drill is a secondhand and rescue. If you are not a professional, then investing in expensive tools may not be a priority. But with the low price, you would want to cover the most basic functionality and reliability. Take a look at the LOM YUM Electric drill, which has all the necessary features in small size and ergonomic shape. The drill is really compact, having rechargeable 16.8V (4x1300mAh Li-Ion) battery pack in its handle. In the feature list, you will find all you need. Durability and reliability are ensured by metal gear and overload protection. It is IPX7 waterproof, so you can use it in harsh conditions. LED light pointed to the drilling area ensures that you always hit the right spot, even in dim environments. The speed control is stepless and can provide up to 18NM of torque.

The Five Main Causes of Data Loss

Data loss is a crisis for most businesses, as all of their essential records, invoices and pieces of customer information become inaccessible. The result? Often substantial financial losses and, in the case of many businesses, a complete business failure. But what exactly causes this data to be lost forever? And, perhaps more importantly, how can these causes be prevented? Below you’ll find the five most common reasons, as well as some helpful tips on stopping them from happening in the first place… It is essential to mention this first, though: however hard you prepare and however many procedures you put in place, it is not always possible to prevent data loss from occurring. This is why all companies should have a contingency plan, which includes some provision for disaster recovery. Losing data will never be a pleasant experience, but with a plan in place, the impact can at least be minimized.

Your Life on a Hard Drive

Imagine what would happen if your hard drive failed. It’s a possibility that most people don’t ever think can happen to them. For the average non-computer geek, their electronic device is infallible. While technological advancements would lead you to believe this, it’s simply not true. The good news is that many companies specialize in data recovery services for most any make of computer on the market. There are things you can do to protect your work and personal items stored on your computer. First, you should always back up your computer and keep the copy disk safe. Unless you’re a business, you probably rarely ever back it up, if at all. This is a huge mistake. Since people practically live on computers, the probability of priceless videos and photos found is given. More than likely, you also keep your bills and other private documents too. In the event of a computer crash, you might lose everything.

5 Things You Didn’t Know About a Mobile Signal Booster

When you can’t talk on the phone without being interrupted inside your house, when you have to run outside the office to get a Skype message, it’s still not a dead end. People use mobile signal boosters to combat this kind of signal trouble. However, all they know about this equipment is that in most cases, it can increase bars but not more. As a result, the notion of a signal booster gets overgrown with prejudices. We decided to make top 5 things you have hardly ever heard about a mobile signal booster so that you can check what you really know about this kind of equipment. As an example, we use Hiboost mobile signal repeater produced by Huaptec. GSM Boosters won’t work if there’s no signal outside. We bet you were always sure that a mobile signal booster would improve a signal anyway, and how well it would do it depends on the booster’s quality. You’re partly right, but that is not the whole story. If you can’t pick up the signal outside your house at all, it’s a strong possibility that you won’t be able to improve cellular signal. It’s connected with the booster working principle. In fact,…
