in that case everyone goes down

Alas, theres always a hacker lurking around, and make no mistake that an online database can be breached by him and him alone. In that case, everyone goes down. Tens of thousands of users just like you. In this there is the safety in numbers element unless the hacker in question decides to sell every bit of data to the highest bidder. The silver lining is that youll know about such a breach almost immediately from your online provider (assuming the company doesnt want a class-action lawsuit.)

Linphone: Encrypted Video and Voice Over IP (VOIP)

Linphone (short for Linux phone) is a free voice over IP, or VoIP service, and SIP client, currently developed by Belledonne Communications in France. Its now available for AppleiOS and Android as well as PCs, with the biggest advantage being it isnt limited to voice and video. You can send texts, chat, make multiple calls and even call up your friends for an audio conference.

Three major new capabilities have been added: a text messaging feature (chat) with delivery status notification, multiple calls and audio conferencing. In addition, Linphone supports audio with speex , G711 ,ILBC, GSM, SILK, G722, OPUS, and video with the VP8 codec.

If you want to talk to your partners using Tor then youll need to use Onioncat at both ends since Linphone uses UDP. Instructions on using Linphone for anonymous VoIP over Tor can be found here, at the Whonix site. Just remember that Tor adds considerable latency so it will not be like those crystal clear calls Jason Bourne gets in a firefight in some back alley in Pakistan.

Thus a series of Dense layers is simply a series of matrix multiplicationsBut

Next, what is “relu” and why do we need it?

Intuitively, we know that each Dense layer involves a matrix multiplication. Thus, a series of Dense layers is simply a series of matrix multiplications.

But, a series of matrix multiplications reduces to a single matrix multiplication, because a matrix multiplied by a matrix is simply another matrix.

E.g.

y = ABCx is the same as y = Wx, where W = ABC

Thus, a single matrix multiplication is equivalent to Logistic Regression (a linear model).

Why are linear models limited?

Recall the general picture of classification: we would like to found a boundary to separate the red dots and blue dots.

The problem is, what if the red dots and blue dots cannot be separated by a line?

Then a linear classifier cannot work.

In this case, we need our function to be nonlinear. We can accomplish this by inserting a nonlinear function in between each matrix multiply (in other words, at the end of each Dense layer).

We call such functions nonlinear activation functions.

In modern deep learning, the most common nonlinear activation function is the ReLU, which stands for “rectifier linear unit”. Don’t be scared by its name, it is just a very simple elbow curve.

consider focusing on a specific niche

Ratings Based on Our Criteria

1. Simplicity:

Creating and maintaining a comparison website can be hard especially if you are not that technically savvy.

5/10

2. Passivity:

Majority of the income you earn from a comparison website is passive income. However, it may require a lot of time commitment since you need to regularly update your comparisons of products – unless you use software to automate this.

7/10

3. Scalability:

To scale your earnings, you need to double the number of entries in your website or you create another one.

7/10

4. Competitiveness:

There are a lot of general comparison websites so competition can be tough. However, you can avoid much of this by going into a specific niche.

Reconnaissance is when the ethical hacker gathers information about the target system

This Includes Scanning Ports To Find Out Which Ones Are Open Or Closed

NETSTAT-A (Displays all connections)

METSTAT-N (Sorts the connections numerically)

NETSTAT-B (Displays executable)

Chapter 3: First Steps

The Process of Ethical Hacking

It is important for an ethical hacker to have a process to structure the hack. These processes can vary depending on the hacker and the companies desire.

Here is an example process to follow:

• Reconnaissance is the first step. Reconnaissance is when the ethical hacker gathers information about the target system.

• The next step is scanning the system. This includes scanning ports to find out which ones are open or closed.

• The next step is attacking the system. This is when the attacker gains access to the system. Metasploit is a useful tool in this phase (see Chapter 10).
