Sure. Try freeCodeCamp (www.freecodecamp.org/) or W3 Schools (www.w3schools.com/).

Unfortunately, the S3 part is from the complete course that's on Udemy.

I was wondering that myself. Unfortunately, I have no clue. As I used to say to my high school students: if ignorance is bliss, this must be the happiest place on earth. :)

I'm not sure what changed, but I note that it's been updated and is now smaller as expected.

@@AdrianMouat Excellent. Makes perfect sense that it was just a weird anomaly.

I selected MariaDB for the demo mostly because I work with it a lot. But there are hundreds of images of all categories available through Chainguard. My understanding is that Chainguard does a good job maintaining their images, and they'd probably push updated images out within days - if not faster. But I'm honestly not sure that'll necessarily help for your in-production images. You might still need to update your build.

@@davidbclinton thanks for your advice and insights. nice work. It seems easy to use the Chainguard images with little downside and several upsides.

The chainguard/mariadb image has been updated - it's now only 329 MB and has 0 CVEs.

@@AdrianMouat Even better!

Hi. I actually can't see your question. Could you send it again?

@@davidbclinton Much love from Nigeria ❤.. Sir I have a question for you.. I am totally new to software development. But I have a strong passion for learning this skill. And I desire to build a School management software for schools here in Nigeria.. This is my question, based on this video this is the starting point towards developing this app. Which architecture is most appropriate How do I get started because freecodecamp has a lot of good resources.. Sir can you provide me a roadmap that I can follow to be able to develop a good School management software.. Thank you sir I anticipate your response sir

@@Beloved_Digital That's a wonderful idea for a project. I'm sure you already know that the final product will involve many technologies deployed across multiple layers. In other words, it'll be complex. But that doesn't mean you shouldn't do it! But I think it does mean that your best resource - at least at the planning stage - is going to be ChatGPT. To illustrate, I just asked it: "Could you create a learning road map for someone looking to acquire the skills he'll need to create a production-ready school management software package?" The answer I got (while I'll paste below) is more than I could have given you. And you'll be able to keep asking follow-up questions until everything is clear. Here's the response: Certainly! Developing a production-ready school management software package involves a combination of software development, project management, and domain-specific knowledge. Here's a learning roadmap to acquire the necessary skills: ### 1. **Fundamentals of Programming** - **Languages**: Python, JavaScript (for web development). - **Concepts**: Object-Oriented Programming, Data Structures, Algorithms. - **Resources**: Online courses (Coursera, Udemy), textbooks. ### 2. **Web Development Basics** - **Frontend**: HTML, CSS, JavaScript, ReactJS or Angular. - **Backend**: Node.js, Python with Django or Flask. - **Database**: SQL (MySQL, PostgreSQL), NoSQL (MongoDB). - **Resources**: FreeCodeCamp, Codecademy, CZcams tutorials. ### 3. **Advanced Web Technologies** - **Frameworks**: Advanced features in Django/Flask (for Python) or Express (for Node.js). - **API Development**: RESTful APIs, GraphQL. - **Authentication & Security**: OAuth, JWT, HTTPS. - **Resources**: Official documentation, specialized courses (e.g., Pluralsight, LinkedIn Learning). ### 4. **Understanding School Management Requirements** - **Domain Knowledge**: School operations, administrative processes. - **User Research**: Interviews, surveys with school staff. - **Resources**: Educational administration books, online forums, seminars. ### 5. **Software Development Best Practices** - **Version Control**: Git, GitHub. - **Testing**: Unit Testing, Integration Testing. - **CI/CD**: Jenkins, GitHub Actions. - **Resources**: GitHub Learning Lab, online tutorials. ### 6. **Project Management** - **Methodologies**: Agile, Scrum. - **Tools**: Jira, Trello. - **Resources**: Project management courses (e.g., PMI, Scrum Alliance). ### 7. **UI/UX Design for Software** - **Principles**: User-Centered Design, Accessibility. - **Tools**: Figma, Adobe XD. - **Resources**: Nielsen Norman Group articles, UX design courses (e.g., Interaction Design Foundation). ### 8. **Deployment and Maintenance** - **Cloud Services**: AWS, Azure, or Google Cloud. - **Monitoring and Scaling**: Load balancing, server management. - **Resources**: Cloud provider tutorials, online courses. ### 9. **Legal and Compliance** - **Data Privacy**: GDPR, FERPA (for educational data). - **Software Licensing**: Understanding different licenses and compliance. - **Resources**: Legal courses for non-lawyers, online resources on software law. ### 10. **Continued Learning and Community Engagement** - **Participate**: Open-source projects, forums like Stack Overflow. - **Stay Updated**: Tech blogs, podcasts, webinars. - **Networking**: LinkedIn, local tech meetups, conferences. ### Supplementary Resources - **Online Communities**: Reddit (r/learnprogramming, r/webdev), Stack Overflow. - **Books**: Specific to technologies and project management. - **Mentorship**: Seek mentors in software development and educational technology. Each of these steps should be tailored based on personal learning pace and the specific requirements of the school management software you are planning to build. It's important to start with a strong foundation in programming and web development, then gradually build on that with more specific skills and knowledge. Remember, practical experience through personal or open-source projects is invaluable. Engage with communities, seek feedback, and iterate on your work. This hands-on experience, combined with the theoretical knowledge, will be crucial in developing a robust, user-friendly, and efficient school management software package.

@@davidbclintonThank you so much for the answer. I have subscribed to your channel sir. I will privilege to learn from you sir

@@Beloved_Digital Great. I expect to hear great things from you!

Great to hear we're neighbours!

Excellent. Great work. This is a really practical certification that comes with serious value.

Yikes. I have no idea how that happened. I'll add a comment when I figure out how to fix this.

Excellent!

Great to hear. Thanks!

Thanks. It's always great to hear real people are actually enjoying this stuff!

It's not that many years ago that the wording confused me, too. :)

Great to hear!

Great to see you enjoyed it!

The simplest way would be to create a port forwarding rule in the public-facing router where your targets live. The rule would permit access only to hosts coming from your public IP address. You may also need to get access to individual hosts within that remote network, but that'll work the same way as on a local network.

Then yesterday was a great day to start. Security matters to everyone - not just big companies.

Binge away!😀And let me know if you find any problems.

@@davidbclinton I would love if you could do more AWS projects on the beginner to intermediate level, if possible!

@@erythsea That's a good idea. I actually once wrote an entire book with that focus (www.amazon.com/dp/1617294446 - although it's a bit old now). I'm going to try to work that kind of project into my schedule. But it may be a while until I can get to it.

@@davidbclinton Out of stock in Canada :(

@@erythsea If you're in Toronto I could give you one of my extra copies.

Thanks!

It's just a typical Amazon short form. This one stands for "Elastic Compute Cloud" (there are two words starting with "C"). It's the platform where you can run virtual servers on AWS.

Whoops. I'll get that fixed!

Fixed. Thanks for bringing that up.

I don't know. I've had pretty good experiences with the community edition lately.

@@davidbclinton Yes for me too, but only with Ubuntu. when I try it with debian there is a lot of issues, I guess the version YML is not compatible with docker compose in debian

@@enzoscandelt3350 That's possible. I've been using primarily Ubuntu by habit for so many years that I sometimes forget there are other distros. :)

@@davidbclinton Yes Ubuntu is always working fine for me. Thanks for the repply

First of all we should do the simple stuff like being aware of the threats and always patching our software. But my security-related courses (and books) are all about carefully applying security best practices at every layer of our infrastructure (even smartphones and PCs). There's a lot we can do even if there's no such thing as *perfect* security.

That's exactly why I'm trying to figure out what all this means. My income comes from creating books and courses, but I'm not sure how many people will need them in five years. But on the other hand, there will also be new opportunities...

I guess that's true. I did struggle to find the right title for this chapter. But I think it's fair to argue that the cloud is where so much of the action is happening these days, so that'll be where most of the interesting platforms exist. And there's also very little overlap between this chapter and the one that was specific to the cloud.

I had more fun with this part of the project than any other. 😀
