R vs Python in Datascience

Data science deals with identifying, representing and extracting meaningful information from data sources to be used to perform some business logics.The data scientist uses machine learning, statistics, probability, linear and logistic regression and more in order to make out some meaningful data. Finding patterns and similar combinations and cracking the best possible path way according to the business logic is the biggest job of analysis.

R, Python, SQL, SAS, Tableau, MATLAB, etc. are of the most useful tools for data science, R and Python being the most used ones. But still, it becomes confusing for any newbie to choose the better or the most suitable one among the two, R and Python. Let’s try to visualize the difference.

Kali Linux on Android using Linux Deploy

Getting Kali Linux to run on ARM hardware has been a major goal for us since day one. So far, we’ve built native images for the Samsung Chromebook, Odroid U2, Raspberry Pi, RK3306, Galaxy Note 10.1, CuBox, Efika MX, and BeagleBone Black to name a few. This however does not mean you cannot install Kali Linux in a chroot on almost any modern device that runs Android. In fact, the developers of Linux Deploy have made it extremely easy to get any number of Linux distributions installed in a chroot environment using a simple GUI builder.

Installing PowerShell on Kali Linux

PowerShell Package Installation in Kali

We begin by installing the necessary dependencies, most of which should already be installed in your Kali installation by default.

apt update && apt -y install curl gnupg apt-transport-https

Next, we need to download and add the public repository GPG key so APT will trust the packages and alert you to any issues with package signatures.

curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add –

With the GPG key added, we proceed to add the Microsoft package repository to its own package list file under /etc/apt/sources.list.d/ and update the list of available packages.

echo “deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-debian-stretch-prod stretch main” > /etc/apt/sources.list.d/powershell.list
apt update

Finally, we proceed to install the powershell package.

apt -y install powershell

Wireguard on Kali

With Wireguard added to the repos, installation is nice and easy:

apt install wireguard resolvconf

And we are off. Next comes time for configuration. This is where Wireguard really shone for us, as it took next to nothing to get up and running.

On the server, we have to generate a public/private key pair and set up an initial config file.

wg genkey | tee privatekey | wg pubkey > publickey
umask u=rwx,go= && cat > /etc/wireguard/wg0.conf << EOF
[Interface]
Address = 10.222.222.1/24
SaveConfig = true
ListenPort = 51820
PrivateKey = -SERVER PRIVATE KEY-

[Peer]
PublicKey = -CLIENT PUBLIC KEY-
AllowedIPs = 10.222.222.2/32
EOF

And we do the same process on the client to establish its key pair and config.

wg genkey | tee privatekey | wg pubkey > publickey
umask u=rwx,go= && cat /etc/wireguard/wg0.conf  << EOF
[Interface]
Address = 10.222.222.2/32
PrivateKey = -CLIENT PRIVATE KEY-
DNS = 8.8.8.8

[Peer]
PublicKey = -SERVER PUBLIC KEY-
Endpoint = public.ip.of.server:51820
AllowedIPs = 0.0.0.0/0
PersistentKeepalive = 21
EOF

How to change iLo hostname on HP Proliant servers

In case you have or administrating HP Proliant servers then you probably know what iLo is. iLo is short from integrated Light-out. On every HP server there is a small chip where iLo is located. So what is iLo? iLo is some kind of hardware monitoring web GUI. iLo is always working but to approach  to iLo you need IP address.

There is default username and password that is located on small paper card that comes with server. Default username is Administrator and password is 8 character random combination of letters and number. Remember that password is case sensitive. It is wise NOT to change password for user Administrator. It is wise to create new user.

How to install Scala in Linux?

Before, we start with the process of Installing Scala on our System. We must have first-hand knowledge of What the Scala Language is and what it actually does? Scala is a general-purpose, high-level, multi-paradigm programming language. It is a pure object-oriented programming language which also provides the support to the functional programming approach. There is no concept of primitive data as everything is an object in Scala. It is designed to express the general programming patterns in a refined, succinct, and type-safe way.

Scala programs can convert to bytecodes and can run on the JVM(Java Virtual Machine). Scala stands for Scalable language. It also provides the Javascript runtimes. Scala is highly influenced by Java and some other programming langauges like Lisp, Haskell, Pizza etc.
Scala is a very compatible language and thus can very easily be installed into the Linux Operating System. The most basic requirement is that we must have Java 1.8 or a greater version installed on our computer.
