Linux Blimp

News briefs for October 11, 2018.

Following the news of Microsoft joining the Open Invention Network, the Free
Software Foundation issued a statement calling on Microsoft to “take
additional steps to continue the momentum toward a complete resolution”.
These steps include “make a clear, unambiguous statement that it has ceased
all patent infringement claims on the use of Linux in Android”; “work
within OIN to expand the definition of what it calls the ‘Linux System’ so
that the list of packages protected from patents actually includes
everything found in a GNU/Linux system”; and “use the past patent royalties
extorted from free software to fund the effective abolition of all patents
covering ideas in software.”

RaspEX Build 181010 is now available for the Raspberry Pi 3 Model B+. It
features the Helium Desktop from BunsenLabs Linux, and according to Softpedia
News, it’s
“based on the latest Ubuntu 18.04 LTS (Bionic Beaver) operating system

Enterprise open source adoption has its own set of challenges, but it becomes easier if you have a clear plan to follow. At Open FinTech Forum, Ibrahim Haddad provides guidelines based on proven practices.

2018 marks the year that open source disrupts yet another industry, and this time it’s financial services. The first-ever Open FinTech Forum, happening October 10-11 in New York City, focuses on the intersection of financial services and open source. It promises to provide attendees with guidance on building internal open source programs along with an in-depth look at cutting-edge technologies being deployed in the financial sector, such as AI, blockchain/distributed ledger, and Kubernetes.

Several factors make Open FinTech Forum special, but the in-depth sessions on day 1 especially stand out. The first day offers five technical tutorials, as well as four working discussions covering open source in an enterprise environment, setting up an open source program office, ensuring license compliance, and best practices for contributing to open source projects.

Enterprise open source adoption has its own set of challenges, but it becomes easier if you have a clear plan to follow. At Open FinTech, I’ll present a tutorial session called “Using Open Source: An Enterprise Guide,” which provides a detailed discussion on how to use open source. We’ll start by answering the question, “Why Open Source,” then discuss how to build an internal supporting infrastructure and look at some lessons learned from over two decades of enterprise open source experience. This session — run under the Chatham House Rule — offers a workshop-style environment that is a mix of presentation and discussion triggered by audience questions. The workshop is divided into five sections, explored below.

Why Open Source?

This question may seem trivial but it’s a very important consideration that even the most open source mature companies revisit regularly. In this part of the workshop, we’ll examine seven key reasons why enterprises should engage with open source software, regardless of industry and focus, and how they can gain incredible value from such engagements.

The Importance of Open Source Strategy

Going through the exercise of establishing an open source strategy is a great way to figure out your company’s current position and its future goals with respect to open source. These strategy discussions will usually evolve around goals you’d like to achieve, along with why and how you’d like to achieve them. In this part of the tutorial, we discuss the many questions to consider when determining your open source strategy and tie that to your product and services strategy for a path to a better ROI.

Implementing an Open Source infrastructure

Once you have identified your company’s open source strategy, you need to build infrastructure to support your open source efforts and investments. That infrastructure should act as a enabler for your efforts in using open source, complying with license, contributing to projects, and leading initiatives. In the workshop, I’ll present these various elements that together form an incredible enabling environment for your open source efforts.

Recommended Practices (17 of them)

When IBM pledged to spend $1 billion on Linux R&D back in 2000, it was a major milestone. IBM was a pioneer in the enterprise open source world, and the company had to learn a lot about working with open source software and the various communities. Other companies have since followed suit, and many more are now entering open source as it becomes the new normal of software development. The question is: How can you minimize the enterprise learning curve on your own open source journey? We’ve got you covered. In this talk, we’ll explore 17 lessons learned from nearly two decades of enterprise experience with open source software.

Challenges

Beyond implementing these best practices, open source adoption requires a cultural shift from traditional software development practices to a more open and collaborative mindset. Internal company dynamics need to be favorable to open source efforts. As an open source leader inside your organization, you will face several challenges in terms of funding resources, justifying ROI, getting upstream focus, etc. These challenges often require a major shift in mindset and a lot of education up the chain. We will explore various considerations relating to culture, processes, tools, continuity, and education to ensure you are on track to open source success in your organization.

We hope to see you at Open FinTech Forum for an informative and high-value event.

ed is a powerful line text editor for the Linux and Unix-like systems. It was one of the first standard Unix text editor developed in 1969 by Ken Thompson. Much older and legacy Unix like system only shipped with ed for the rescue purpose. There was no vi. So learning ed might be a good idea. A low-level understanding of ed editor helps when one uses a high-level application such as vi or vim. The “Ed Mastery” book teaches you how to use the ed and forgotten art of Unix where the line-oriented paradigm is the only option. The author describe book as, “If you don’t know ed, you’re not a real sysadmin. Forty years after ed’s introduction, author Michael W Lucas has finally unlocked the mysteries of ed for everyone. With Ed Mastery, you too can become a proper Unix sysadmin.”

Ed Mastery

There are eight chapters. Each chapter introduces to basic concepts of ed text editor. These chapters teach you concepts such as:

1. Getting started with ed
2. How to view, print, delete, find/replace and edit a file
3. How to enter and end all commands
4. Advanced search and replace text
5. File management (writing or loading files) and running Unix shell commands
6. Moving around a file or append something to the file
7. Shell scripting and more.

The author covered FreeBSD (macOS) and Linux version of ed with some feature specific to Linux or FreeBSD only.

The modern text editor such as vim or emacs is arguably one of the best text editors in existence. But, they lack the simplicity of ed. Unix like system known for its simplicity and KISS (Keep It Simple Stupid), principles. If someone wants to learn ed, grab this book. Much of stuff learned in this book can apply to other applications. Some might say ed is hard to learn. Ed’s learning curve is steep but “Ed Mastery” will take away the fear of learning line editor.

The book is available in two editions as follows:

1. Ed Mastery: The Standard Unix Text Editor (IT Mastery) – Priced at $9.99
2. Ed Mastery: Manly McManface Edition: The Standard Unix Text Editor – Every so often, men contact the author complaining that his books use both male and female pronouns. This special edition, using only male third-person pronouns, is for those special people. As the market is so much smaller, it’s unfortunately priced higher. For each copy of the Manly McManface edition sold, the author will donate one dollar to his local chapter of Soroptomists International – Priced at $29.99

After months of user testing in developer and beta channels, the Crostini project at Google finally delivered the goods, Linux apps for most users of Chromebooks in the stable channeldefinitely worth the wait. While this still is aimed primarily at developers using Chromebooks, I think there’s a good chance these Linux apps will be used and enjoyed by the general public using Chromebooks as well. There’s still a bit of a learning curve to overcome before that possibility is realized, but if you already are a user of any Linux distro, it will feel very familiar. Here’s an overview of how to install it and what to expect afterward.

After getting the update to version 69, go to Settings and scroll down a bit, and you’ll see the option to turn on Linux apps. Figure 1 shows this first step. Note that this isn’t available on all Chromebooks; if you’re using an older one, you’ll have to wait a while before this function is available. If you don’t see the option to turn on Linux apps, your Chromebook currently lacks that functionality. But, if you have a Chromebook produced in the past two years, you probably will see the option.

Today you’ll learn how to spoof your MAC address in Kali Linux using macchanger.

Before I start, there are two ways to go about changing your MAC address in Kali Linux.

1. Using Macchanger
2. Manually​

I’ll be showing you how to do both.

​So, what is macchanger?

Macchanger is a free MAC address manipulation tool that comes pre-installed in Kali Linux.

In short, Macchanger makes it easy to spoof or change your MAC address.

Here’s a quick how-to navigation for those who want to jump ahead.

NOTE: If macchanger is not installed on your system, follow the steps below to install it.

How to install Macchanger

Open up a terminal and type the following:

sudo apt-get install macchanger

During the installation process, you’ll be asked if you want to spoof the MAC address each time you attach a ethernet cable or a network adapter.

If you select yes, you’ll automatically be assigned a new MAC address for each interface brought up or plugged in. It’s up to you if you want to enable this or not.

It’s up to you if you want to enable this or not.

If you have mac-filtering enabled on your router, you’ll want to select NO on this one; otherwise, you won’t be able to connect to your own wifi.

Afterwards, check to make sure it’s installed and working by typing “macchanger” in the terminal.

It should look like this:

How to display available network interfaces

Next, we need to determine the interface we want to spoof.

To list all available network interfaces on your system, type the following command:

ifconfig

Depending on which interface you want to spoof, you’ll want to make sure you use the name of your interface. Mine is “wlan0.”

Now that we know what interface to use, it’s time to get spoofin!

Bring down the interface you want to spoof

If you spoof without bringing down the interface, you’ll get the “insufficient permission” or “device is busy” error.

You must always bring the interface down before changing the MAC address.

Here’s how:

ifconfig wlan0 down

Remember to replace “wlan0” with your interface.

Print your MAC address

This will show you the current (and permanent) MAC address of an interface.

-s = print the MAC address

macchanger -s wlan0​

Set (specify) your MAC address

This will set your MAC address to whatever value you assign it.

-m = set the MAC address

macchanger -m 11:22:33:44:55:66 wlan0

Change MAC address to a random vendor

This will randomize your MAC address and it will use one from a known vendor.

NOTE: A vendor is the manufacturer of the network interface card (ie. TP-LINK TECHNOLOGIES CO., LTD)

-A = set a random MAC address of any kind.

macchanger -A wlan0

Change MAC address but use the same vendor

This will randomize your MAC address but it will use the same vendor as your current one.

-a = set a random MAC address of the same kind

macchanger -a wlan0

Change to a fully random MAC address with no vendor

This will set a fully random MAC address with no vendor.

If you were to use a MAC address lookup tool, it won’t be able to detect the manufacturer because it’s completely made up.

-r = set a fully random MAC address

macchanger -r wlan0

Reset (change back) to original MAC address

This will revert the changes and it will go back to using the permanent MAC address of the interface.

-p = reset to original MAC address ​

macchanger -p wlan0

View a list of known MAC vendors

If you want to set your own MAC address, this will show you a huge list of legit MAC vendors ​you can choose from.

-l = print known vendors

macchanger -l

NOTE: After making changes to the MAC address, you’ll need to bring the interface back up by typing: ifconfig wlan0 up.

How to manually change MAC address (without using macchanger)

If you don’t have macchanger installed, here’s how to change your MAC address manually.

For this to work, you have to use a MAC address from a known vendor. Fully random MAC address won’t always work.

ifconfig wlan0 down
ifconfig ​wlan0 hw ether fc:c7:34:12:bc:1c
ifconfig wlan0 up

That’s it! Let me know if you have any questions. I’ll be glad to help.

In this lesson, we will look at some most popular GUI tools to access

MySQL database

on Ubuntu 18.04. These vary in application size and ease of use but they are useful for some features specific to each application only. We will look at these GUI tools and features they offer differently in this post. Let’s get started.

MySQL GUI Tools for Ubuntu 18.04

Sequel Pro

Sequel Pro is an excellent and lightweight tool to access MySQL on local and remote machines. If you are looking for a tool which contains a simple purpose to access MySQL on local and remote machines, this is a very lightweight tool which allows you to quickly connect to a given database with necessary details:

MySQL GUI Tool: Sequel Pro

As seen in the image above, it allows us to connect to the database through SSH, Socket or Standard connection details. It is possible to save favourite connections so that we can connect to them again whenever needed quickly.

MySQL Workbench

The MySQL Workbench is a tool which is used for many more features than just accessing the database. First, we look at the primary feature this tool provides to us, connecting to a database:

MySQL GUI Tool: MySQL Workbench

Clearly, it also provides the same features to connect to a remote database as provided by the Sequel Pro tool we saw before. Apart from this, MySQL Workbench allows us to read tables and convert them directly to EER Diagrams with these steps:

Table to ER Diagram

The process is called Reverse Engineering. Once it is complete, we will see simply the required result:

Table to EER Diagram

This is an excellent use to prepare documentation for the currently existing databases and tables & much faster as well than manual work. It is helpful not only to the database administrators but architects and developers as well.

dbForge Studio for MySQL

The dbForge Studio for MySQL has been stated one of the most intelligent service to work with MySQL and MariaDB as well:

dbForge Studio for MySQL

It is a universal GUI tool for MySQL and MariaDB database development, management, and administration. According to its creators: “The IDE allows us to create and execute queries, develop and debug stored routines, automate database object management, analyze table data via an intuitive interface”. Just like MySQL Workbench, dbForge Studio also allows visual designer for a database:

dbForge Studio

The building, editing, and running queries, as well as measuring and optimizing query performance get much simpler with the following functionality:

• MySQL Debugger
• MySQL Code Completion
• Query Profiler
• SQL code formatting
• SQL syntax check

Try these functionalities and make use of this excellent.

DBManager Professional

The DBManager Professional’s flexibility makes it ideal for today’s rapidly changing business environment, as it is able to manage all the aspects concerning data management. Also, it has a built-in support for today’s most used database engines: MySQL, PostgreSQL, Interbase/Firebird, SQLite, DBF, MSAccess, MSSQL Server, Sybase and Oracle. Advanced User Interface, Powerful Features, Easy Database Integration.

Conclusion

In this lesson, we looked at the four most used MySQL GUI tools which are used across Operating Systems with amazing features and tools to ease the process of Database designing, modelling and debugging.
