Monday, December 18th, 2023

Greetings, remote warriors! Today, we’re diving into a bit of tech wizardry that’s both incredibly useful and surprisingly straightforward. It’s all about resurrecting the charm of DOS in the modern era, and we’re doing it with Rufus, a nifty little tool that turns your USB drive into a DOS-powered machine.

Why Would you need to create a bootable drive?

Why would someone in this age need DOS? Well, imagine you’ve got some old-school software that refuses to play nice with Windows 10, or perhaps you need to recover data from a computer that’s seen better days. That’s where FreeDOS, a modern spin on the classic MS-DOS, comes into play. And Rufus? That’s your magic wand to make it happen.

Here’s the deal with Rufus: it’s free, open-source, and as clean as a whistle – no malware or viruses here. You can grab it from its official website. Now, let’s get our hands dirty (not literally, though).

Step-by-Step Guide to Creating a Bootable DOS USB Drive with Rufus

Prerequisites:

  • A USB flash drive (minimum capacity 2 GB recommended).
  • A computer with internet access to download Rufus and FreeDOS.
  • Ensure all important data on the USB drive is backed up, as the process will erase all data on it.

Step 1: Download Rufus

  1. Navigate to the official Rufus website: https://rufus.ie/en/
  2. Download the latest version of Rufus.

Step 2: Prepare the USB Drive

  1. Insert your USB flash drive into an available USB port on your computer.
  2. Ensure the drive is recognized by your operating system.

Step 3: Launch Rufus

  1. Locate the downloaded Rufus executable file.
  2. Run Rufus. Note: Rufus does not require installation and can be run directly.

Step 4: Configure Rufus Settings

  1. In Rufus, under the ‘Device’ section, select your USB drive from the dropdown menu.
  2. In the ‘Boot selection’ section, choose ‘FreeDOS’ from the dropdown list.
    • For specific needs, select ‘FreeDOS (non-free drivers)’ to include additional driver support.
  3. Under ‘Partition scheme’, choose ‘MBR’ or ‘GPT’ based on your system requirements.
    • MBR (Master Boot Record) is generally suitable for older systems.
    • GPT (GUID Partition Table) is used for newer systems.
  4. Ensure the ‘File system’ is set to ‘FAT32’, which is compatible with DOS environments.
  5. Assign a ‘Volume label’ as desired (e.g., DOS_USB).
  6. Under ‘Advanced format options’, ensure ‘Quick format’ is checked for faster formatting.

Step 5: Start the Creation Process

  1. Click the ‘Start’ button in Rufus.
  2. A warning message will appear indicating that all data on the USB drive will be destroyed. Confirm by clicking ‘OK’.

Step 6: Monitor the Process

  1. Rufus will format the USB drive and install FreeDOS.
  2. Observe the progress bar. The process may take a few minutes depending on the speed of the USB drive and the computer.

Step 7: Completing the Process

  1. Once Rufus indicates ‘READY’ at the bottom of the window, the bootable DOS USB drive creation is complete.
  2. Safely eject the USB drive from your computer.

Step 8: Using the Bootable DOS USB Drive

  1. Insert the bootable DOS USB drive into the target computer.
  2. Reboot the computer.
  3. Access the BIOS/UEFI settings during startup (usually by pressing keys like F2, F12, Del, etc.).
  4. In the BIOS/UEFI menu, navigate to the boot options and set the USB drive as the first boot device.
  5. Save the settings and exit the BIOS/UEFI.
  6. The computer will restart, and you should be greeted with the FreeDOS command prompt.

Tips and Troubleshooting:

  • If the computer does not boot from the USB drive, recheck the BIOS/UEFI settings for boot order.
  • Ensure the USB drive is properly formatted and the bootable creation process in Rufus was successful.
  • If encountering issues with Rufus, consider redownloading the software or using a different USB drive.

By following these steps, you should successfully create a bootable DOS USB drive using Rufus, suitable for running DOS-compatible applications and utilities.

Wrapping Up


In conclusion, combining Rufus with FreeDOS is akin to equipping yourself with a versatile tech tool, much like a Swiss Army knife for your digital endeavors. This potent duo is not only straightforward and user-friendly but also robust in its capabilities.

Whether you’re aiming to breathe life into vintage software, retrieve data from systems that have seen better days, or simply indulge in some tech nostalgia, Rufus and FreeDOS are your reliable allies. Beyond their practical applications, the open-source nature of FreeDOS adds a layer of flexibility, allowing users to freely use, adapt, and share it without the constraints of legal or financial barriers.

This makes the Rufus and FreeDOS combination an invaluable asset for developers, technical professionals, and even savvy personal users who appreciate the essence of classic computing in a modern context. Happy computing as you explore and leverage the dynamic capabilities of Rufus and FreeDOS!

0500 to 05:00 – Excel Cell Formatting

Monday, December 4th, 2023

If you use an Excel spreadsheet to keep track of tasks and time associated with it, it’s cumbersome to constantly type in XX:YY.

Here is a short technique to format the cell so when I enter a time (0500), it will automatically convert it to 05:00.

To format a cell in Excel 2019 so that when you enter “0500”, it automatically converts to “05:00”, you can use a custom format. Here’s how to do it:

  1. Select the cell or range of cells where you want to apply this formatting.
  2. Right-click on the selected cell(s) and choose ‘Format Cells’ from the context menu.
  3. In the ‘Format Cells’ dialog box, go to the ‘Number’ tab.
  4. Choose ‘Custom’ from the category list.
  5. In the ‘Type’ field, enter the custom format: 00":"00. This format tells Excel to split the number into two pairs of digits, separated by a colon.
  6. Click ‘OK’ to apply the formatting.

Now, when you enter a number like 0500 in the cell, it will automatically be displayed as 05:00. Note that this is a display format and the underlying value in the cell will still be 0500. This method is best for display purposes and won’t actually change the data into a time value. If you need to perform time calculations, you might need a different approach to convert the input into a proper time format.

Online Classes – The Rise of Massive Open Online Courses (MOOC)

Wednesday, November 22nd, 2023

In the past decade, a quiet revolution has been unfolding in the realm of education. It’s not happening within the hallowed halls of prestigious universities or in high-tech laboratories, but rather in the vast, interconnected world of the internet. This revolution has a name: MOOC, or Massive Open Online Courses. These online platforms are reshaping how we think about education, breaking down barriers and opening up a world of knowledge to anyone with an internet connection.

Introduction – Unlocking the World of Learning Through MOOCs

Imagine being able to attend a lecture by a top Harvard professor while sitting in your living room in Madrid, or joining a coding class taught by a Silicon Valley expert from a small town in India. MOOCs make this possible. They offer an array of courses covering everything from philosophy to artificial intelligence, often for free or at a minimal cost. This unprecedented access to education is not just a convenience; it’s a transformative force that’s democratizing knowledge.

The Catalyst of Change

But what exactly led to the emergence of MOOCs? The answer lies in the intersection of technology and a growing demand for flexible, inclusive education. The digital age has provided the tools – high-speed internet, video streaming, interactive platforms – while a globalized world has created a thirst for diverse, accessible learning opportunities. MOOCs emerged as a response to this, fueled by the vision of educators and innovators who saw the potential of the internet as a limitless classroom.

A New Era of Learning

MOOCs represent more than just online courses; they are a new paradigm in education. They challenge the traditional model of learning, which is often restricted by geographical, financial, and institutional boundaries. By offering courses that anyone can take from anywhere, MOOCs are not just educating; they are empowering. They are tools for personal growth, professional development, and global understanding.

The Growing Popularity of MOOCs

The popularity of MOOCs has skyrocketed in recent years. Millions of learners worldwide have enrolled in courses, and this number is growing daily. People from all walks of life – students, professionals, retirees, and lifelong learners – are seizing the opportunity to learn new skills, broaden their horizons, and even change their career paths.

The Journey Ahead

As we embark on this exploration of MOOCs, we will delve into their history, the factors that distinguish a great MOOC from a mediocre one, and the top platforms that offer these courses. We will also guide you on how to choose the right MOOC for your needs and provide a list of free classes to get you started. This journey through the world of MOOCs is not just about understanding a digital education phenomenon; it’s about recognizing and embracing the endless possibilities that come with the power of learning.

The Evolution of MOOCs: A Journey from Niche to Mainstream

The seeds of MOOCs were planted in the early 2000s, a time when online learning was still in its infancy. Initially, these courses were little more than digitized versions of traditional classroom materials. However, visionaries in the education sector saw potential for something greater: a platform that could offer high-quality education to anyone, regardless of location or background.

The Breakthrough Moment

The real breakthrough for MOOCs came in 2008 with the launch of a course called “Connectivism and Connective Knowledge.” Offered by the University of Manitoba, this course was the first to be labeled a MOOC. It brought together over 2,500 participants from around the world, demonstrating the massive potential of online courses. The success of this course sparked interest across the globe, leading to the development of more MOOCs.

The Role of Technology

As technology advanced, so did MOOCs. Video lectures, interactive quizzes, peer-to-peer learning platforms, and AI-driven personalized learning experiences transformed these courses from simple text-based materials to dynamic, engaging learning environments. These technological enhancements made MOOCs not just an alternative to traditional education but, in some cases, a preferred mode of learning.

The Surge of Major Platforms

The early 2010s witnessed the emergence of major MOOC platforms like Coursera, edX, and Udacity. These platforms partnered with top universities and institutions, offering courses in a wide range of disciplines. The content was not just informative but also designed to be interactive and engaging, appealing to a global audience.

MOOCs Go Mainstream

By the mid-2010s, MOOCs had gone mainstream. They were no longer seen as a novelty but as a vital part of the educational landscape. Universities started recognizing MOOCs for credit, and companies began using them for employee training. The MOOC movement had gained significant momentum, with millions of learners enrolling each year.

The Pandemic and Beyond

The COVID-19 pandemic marked another pivotal moment for MOOCs. With educational institutions worldwide forced to close, MOOCs became an essential tool for uninterrupted learning. This period saw a surge in enrollments and also a rapid evolution in MOOC offerings, with more focus on employability and skill-based courses.

The Future of MOOCs

Today, MOOCs stand at the forefront of an educational revolution. They continue to evolve, incorporating advanced technologies like virtual and augmented reality, offering more personalized learning experiences, and expanding their reach. The future of MOOCs is not just about content delivery; it’s about creating a global community of learners, educators, and innovators.

Understanding MOOCs: The Good, The Bad, and the Path Forward

in this section, we provide a balanced view of MOOCs, discussing both their strengths and the challenges they face. We focus on solutions and the path forward sets the stage for the next section, which will delve into the top MOOC providers and their unique offerings.

The Bright Side of MOOCs

  1. Unparalleled Accessibility: MOOCs have torn down geographical and financial barriers to education. Anyone with an internet connection can access courses from prestigious universities, making high-quality education a reality for people who previously couldn’t afford it or were geographically isolated.

  4. Building a Global Learning Community: MOOCs create virtual classrooms where individuals from around the world can connect, share ideas, and collaborate. This global networking opportunity enriches the learning experience and fosters cultural exchange.

The Challenges of MOOCs

  1. Low Completion Rates: One of the biggest challenges with MOOCs is that many enrollees don’t complete their courses. The reasons vary from lack of time, motivation, or the absence of a tangible reward upon completion.
  2. Quality and Consistency Issues: With thousands of courses available, the quality can vary significantly. Some courses offer an in-depth and engaging learning experience, while others might be poorly structured or lack depth.
  3. Limited Recognition and Accreditation: While some employers recognize the value of MOOCs, many courses still lack formal accreditation. This can limit their utility for career advancement or academic credit.
  4. The Digital Divide: Despite their accessibility, MOOCs still require a reliable internet connection and a computer, which can be a barrier in less developed regions.

Moving Forward: Enhancing the MOOC Experience

  1. Improving Engagement and Completion Rates: Course creators are continually exploring ways to enhance engagement, such as interactive content, gamification, and community-building activities. Some institutions are also offering certificates or credits as incentives for completion.
  2. Focusing on Quality: As the MOOC market matures, there’s a growing emphasis on maintaining high-quality content. Peer reviews, feedback systems, and collaborations with renowned educators and institutions are steps in this direction.
  3. Bridging the Accreditation Gap: Some MOOCs are now offering micro-credentials and professional certificates that carry more weight in the job market. Partnerships between MOOC platforms and universities are also leading to courses that can count towards college credit.
  4. Addressing the Digital Divide: Efforts are underway to make MOOCs more accessible in regions with limited internet access. This includes offline learning options, mobile-friendly courses, and partnerships with local educational institutions.

Changing Hosts – Things to Keep in Mind

Tuesday, March 7th, 2023

Whether you are migrating from an old host to a new one, or splitting a website away from the existing hosting package and assigning it to a new package, there are several things to keep mind.

If you are using WordPress and some type of shared hosting, make sure to disable and uninstall WORDFENCE security plugin as it contains files that will cause problems.

If you use Cloudflare

  • Your server IP address will change so you will need to update the IP address and server name from your Cloudflare dashboard

If you use Wordfence

  • There is a good chance that some Wordfence files will continue to point to the old host after the migration. In that case, you most likely will see HTTP 500 Error message, preventing you from accessing the site (a technician will need to manually make adjustments).
  • To keep it simple, disable to uninstall Wordfence before performing the migration steps

Website Migration Steps

  • Step #1 – Take a screenshot of the WP Benchmark Tool’s performance results
  • Step #2 – Disable and uninstall Wordfence plugin
  • Step #3 – Perform a backup from the WordPress dashboard (old host)
  • Step #4 – Restore the WordPress backup files (new host)
  • Step #5 – From your Cloudflare dashboard, click on the DNS link and update the IP Address and Server name
  • Step #6 – Take a screenshot of the WP Benchmark Tool’s performance results and compare
  • Step #7 – If you are using a cache plugin (i.e. LiteSpeed), you need to purge all cache

Yoda’s Quotes

Monday, December 5th, 2022

“Do or do not. There is no try.”

This quote is a simple lesson in commitment and the power in giving something our all—not just giving it a try.

“You must unlearn what you have learned.”

As creatures of habit, we tend to love our routines and our go-to methods. But sometimes, we have to shake up our process—and even unlearn our process—to succeed.

“Named must be your fear before banish it you can.”

When we call out our fears directly, they become less of an ominous force and a challenge we can tackle head-on.

“Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering.”

Indulging our fears (whether with our thoughts or actions) gives them power to hold us back. And Yoda points out how our fears can impact those around us, too.

“That is why you fail.”

When Luke says he doesn’t believe in the power of the force, Yoda serves up this piece of wisdom. We have to believe in ourselves—and our abilities—in order to persevere and succeed. Without faith, we can only go so far.

“The greatest teacher, failure is.”

We learn from our mistakes—plain and simple.

“Pass on what you have learned.”

The wisdom we gain in life is a gift to pass along—not to keep to ourselves. Make like Yoda and share your insights with others.
