Create a two-dimensional array with the flattened input as an upper diagonal in Numpy
To create a two-dimensional array with the flattened input as a diagonal, use the numpy.diagflat() method in Python Numpy. The 'K parameter is used to set the diagonal; 0, the default, corresponds to the “main” diagonal, a positive (negative) k giving the number of the diagonal above (below) the main.The first parameter is the input data, which is flattened and set as the k-th diagonal of the output. The second parameter is the diagonal to set; 0, the default, corresponds to the “main” diagonal, a positive (negative) k giving the number of the diagonal above (below) the main.NumPy offers comprehensive ...

The second parameter is the diagonal to set; 0, the default, corresponds to the “main” diagonal, a positive (negative) k giving the number of the diagonal above (below) the main.NumPy offers comprehensive mathematical functions, random number generators, linear algebra routines, Fourier transforms, and more. It supports a wide range of hardware and computing platforms, and plays well with distributed, GPU, and sparse ...
Read MoreReturn numbers spaced evenly on a geometric progression in Numpy
To return evenly spaced numbers on a geometric progression, use the numpy.geomspace() method in Python Numpy. The 1st parameter is the "start" i.e. the start of the sequence. The 2nd parameter is the "end" i.e. the end of the sequence. The 3rd parameter is the num i.e. the number of samples to generate.The start is the starting value of the sequence. The stop if the final value of the sequence, unless endpoint is False. In that case, num + 1 values are spaced over the interval in log-space, of which all but the last (a sequence of length num) are ...
Read MoreReturn evenly spaced numbers on a log scale and do not set the endpoint in Numpy
To return evenly spaced numbers on a log scale, use the numpy.logspace() method in Python Numpy. The 1st parameter is the "start" i.e. the start of the sequence. The 2nd parameter is the "end" i.e. the end of the sequence. The 3rd parameter is the "num" i.e. the number of samples to generate. Default is 50. The 4th parameter is the "endpoint". If True, stop is the last sample. Otherwise, it is not included. Default is True.In linear space, the sequence starts at base ** start (base to the power of start) and ends with base ** stop (see endpoint ...
Read MoreWhat is Sim Swap Scam?
You're not alone if you use your phone to check your email, pay your bills, or post to social media. Consider what would happen if your phone suddenly stopped working: no data, no text messages, no phone calls.

These could be symptoms of your SIM card being switched and your phone number being stolen.This article will explain what SIM swapping is and what the big phone providers are doing about it. We'll highlight individual wireless carriers' answers ...
Read MoreWhat is a Shortcut Virus and how to remove it?
The transmission of computer viruses has become too prevalent in this age of broad multimedia sharing and online surfing. The shortcut virus, on the other hand, has become all too familiar, and we've all seen it someplace in our pen drives, PCs, and laptops and wondered why there's a copy of that exactly replicated folder? You can solve this problem by utilizing portable antivirus software.Most of us have always neglected this virus because it does not appear to be particularly harmful. However, as the saying goes, never underestimate anyone, especially a virus, and it would be a mistake to do ...

Have you ever felt as if your phone knew a little too much about you? It's not a figment of your imagination. There's a steady stream of data arriving from your device, from location tracking to trackers that follow you across the web.Some apps can even access your phone's microphone or camera without your permission when you aren't looking. You may have noticed on your phone a recommendation for a product you recently discussed with a friend; how can it be so accurate, and why do they do it? Let's dig deeper and find the answers.Is it possible for phones ...
Read MoreDifference between Tokenization and Encryption
Today, every firm, large or small, collects, stores, receives or transmits data to some extent. This data must be protected regardless of which device, technology, or method is used to manage, store, or gather it. This is when data security comes into play. We will limit our discussion to file and database encryption methods, even though data security is a term that embraces all aspects of information security.By hiding critical information's contents through encryption or tokenization, these technologies provide a last line of defence. Let's look at the two terms for data security in more detail.TokenizationTokenization is a mechanism for ...
Read MoreWhy is IPv6 preferred over IPv4?
The Internet Protocol, or IP, is a set of rules that allows our computers and other communication devices to communicate via the Internet. When you open a website on your browser, a data packet including your IP address is transmitted to the web server's IP address, and the website is then served back to your device over the Internet.IP addresses function similarly as street addresses on a map do. They are in charge of directing packets to their correct destinations. IP controls all Internet traffic. Data packets containing the IP addresses of their points of origin and destinations travel on ...
