How can libraries ensure the security of their data and protect patron privacy when using a library management system?

In today's digital age, libraries rely heavily on technology to manage their collections, provide access to resources, and serve their patrons. However, with the use of technology comes the risk of data breaches and privacy violations. As libraries increasingly adopt library management systems, it is important to consider how these systems can be secured to protect patron privacy and ensure the integrity of library data.

At Metaguard, we understand the importance of data security and privacy in the library setting. Our team of experts works with libraries to implement security measures and provide training and support to ensure that library management systems are secure and compliant with privacy regulations.

One of the first steps libraries can take to ensure data security and privacy is to implement access controls. Access controls limit who has access to sensitive data and ensure that only authorized personnel can view and modify data. Libraries can also implement multi-factor authentication to further enhance security and prevent unauthorized access.

Another important step is to ensure that all data is encrypted when it is transmitted or stored. Encryption ensures that data is protected from hackers and other unauthorized users. Libraries should also regularly update their software and systems to ensure that they are protected from known security vulnerabilities.

In addition to securing the library management system, libraries must also protect patron privacy. This includes implementing policies and procedures for handling and storing patron data, as well as obtaining consent before collecting any personal information. Libraries should also provide clear and transparent privacy policies to patrons and ensure that they are informed about how their data is being used and protected.

At Metaguard, we work with libraries to implement privacy and security best practices, including regular audits and assessments to identify and address potential vulnerabilities. We also provide training and support to library staff to ensure that they have the knowledge and skills to maintain a secure and privacy-compliant library management system.

In conclusion, library management systems are an essential tool for modern libraries, but they also come with security and privacy risks. By implementing access controls, encryption, and other security measures, libraries can protect their data and ensure the integrity of their systems. At Metaguard, we are committed to helping libraries achieve these goals and providing the necessary support and training to ensure that data security and privacy remain a top priority.

Lazy Loading Page Speed Optimization: Efficient Practices & Tips

Key Takeaways

Lazy loading can significantly improve page speed by loading only necessary content initially, reducing initial load times.

Implementing lazy loading can save bandwidth, which is crucial for users on limited data plans.

This technique enhances user experience by ensuring faster interactions and smoother scrolling.

SEO can benefit from lazy loading as search engines prefer faster websites, potentially improving rankings.

To effectively implement lazy loading, use browser-native features and ensure compatibility across different devices.

Enhancing Web Performance with Lazy Loading

In today's fast-paced digital world, web performance is more critical than ever. Slow websites can drive users away, impacting engagement and conversions. One powerful technique to boost performance is lazy loading. By understanding and implementing lazy loading, you can optimize your website's speed and efficiency, keeping your visitors engaged and satisfied.

Understanding the Need for Speed

Users expect websites to load quickly and efficiently.

Slow loading times can lead to higher bounce rates.

Improved speed enhances user satisfaction and retention.

Most importantly, speed is not just a luxury; it's a necessity. Users are increasingly impatient, and a delay of even a few seconds can cause them to abandon your site. Therefore, ensuring that your site loads swiftly is crucial for maintaining user interest and engagement.

Lazy loading offers a solution by optimizing the loading process. Instead of loading every element of a page at once, lazy loading prioritizes essential content and defers non-essential elements. This approach can make a dramatic difference in how quickly your site feels to users.

Lazy Loading: A Game Changer for Web Efficiency

Lazy loading is more than just a buzzword; it's a transformative technique for web optimization. By deferring the loading of non-essential elements, such as images and videos, until they are needed, lazy loading reduces the initial load time of a webpage.

Images and videos load only when they enter the viewport.

Reduces server requests, enhancing page speed.

Particularly beneficial for mobile users with limited bandwidth.

Besides that, lazy loading helps in conserving resources, which is particularly beneficial for mobile users who might be on limited data plans. By only loading what's necessary, users experience faster interactions and smoother scrolling, which can significantly improve their overall experience.

Eager Loading: When Immediate Isn't Ideal

Eager loading, the opposite of lazy loading, involves loading all page elements at once. While this approach might seem straightforward, it can lead to longer initial load times, especially on content-heavy pages. Therefore, eager loading is not always the best choice, particularly when dealing with large images or videos.

Lazy loading, on the other hand, ensures that your website delivers essential content swiftly, making it an ideal choice for optimizing page speed and improving user experience.

Benefits of Lazy Loading

Lazy loading isn't just about speed; it's about creating a seamless and efficient user experience. Let's delve into the various benefits it offers.

Faster Initial Load Times

By loading only the necessary elements initially, lazy loading significantly reduces the time it takes for a page to become interactive. Users can start engaging with the content almost immediately, without waiting for all elements to load.

This immediate engagement is crucial in retaining user interest. For instance, if your homepage loads quickly, users are more likely to explore further, increasing the chances of conversion.

Additionally, faster load times can have a positive impact on your website's bounce rate. Users are less likely to leave if they don't have to wait for content to load, which can improve your site's overall performance metrics.

Loading Images Efficiently

Images often account for the majority of a webpage's load time. By implementing lazy loading for images, you can significantly improve your page speed. This involves loading images only when they are about to enter the viewport. As a result, users won't have to wait for all images to load before they can interact with your content.

To do this effectively, you can use the loading="lazy" attribute in your image tags. This attribute tells the browser to defer loading the image until it is close to being visible. Additionally, consider using responsive image techniques to serve different image sizes based on the user's device, further optimizing load times.

Handling Videos and Media Content

Videos and other media content can be resource-intensive, causing significant delays in load times if not managed properly. Lazy loading can also be applied to these elements. By embedding videos with lazy loading techniques, you ensure they only load when a user scrolls to them.

For example, instead of directly embedding a video, use a thumbnail image with a play button overlay. When the user clicks the play button, the video loads and plays. This not only saves bandwidth but also improves the initial loading speed of the page.

JavaScript and CSS Deferred Loading

JavaScript and CSS files are essential for modern web applications, but they can also be a bottleneck if not handled correctly. Lazy loading these resources involves deferring their loading until they are needed. This can be achieved using the defer and async attributes for JavaScript files.

The defer attribute ensures that the script is executed after the HTML document has been parsed, while the async attribute allows the script to be executed as soon as it's available. For CSS, consider using media queries to load stylesheets conditionally based on the user's device or viewport size.

Tips for Optimizing Lazy Loading

Implementing lazy loading is just the beginning. To truly optimize your website's performance, follow these additional tips and best practices.

Use Browser Native Features

Modern browsers offer native support for lazy loading, making it easier than ever to implement this technique. By using native features, you can ensure compatibility and reduce the need for third-party libraries, which can add unnecessary overhead.

To take advantage of these features, simply add the loading="lazy" attribute to your image and iframe tags. This simple addition can have a significant impact on your page speed, especially for image-heavy sites.

Besides, using native features ensures that your site remains future-proof, as browsers continue to enhance their support for lazy loading and other performance optimizations.

Minimize Default Image Size

Before applying lazy loading, it's crucial to optimize your images for size. Large images can still slow down load times, even with lazy loading. Use image compression tools to reduce file sizes without sacrificing quality.

Optimize Animations

Animations can enhance user experience, but they can also impact performance if not optimized. Use CSS animations instead of JavaScript whenever possible, as they are more efficient and can be hardware-accelerated by the browser.

Ensure that animations are smooth and don't cause layout shifts, which can negatively affect user experience. Test your animations on different devices to ensure they perform well across the board.

Remember, the goal is to create a seamless experience for your users. By optimizing animations, you can enhance the visual appeal of your site without compromising performance.

Test Across Multiple Devices

It's essential to test your website on a variety of devices and screen sizes. What works well on a desktop might not perform the same on a mobile device. Use tools like Google PageSpeed Insights to analyze your site's performance and identify areas for improvement.

Regular testing ensures that your lazy loading implementation works as intended across different platforms, providing a consistent experience for all users.

Overcoming Common Lazy Loading Challenges

While lazy loading offers numerous benefits, it's not without its challenges. Addressing these issues ensures that your implementation is successful and doesn't negatively impact your site.

Dealing with SEO Concerns

Lazy loading can sometimes interfere with search engine indexing if not implemented correctly. To ensure your content is indexed, use server-side rendering or provide fallbacks for search engines that may not execute JavaScript. For more insights, check out how lazy loading decreases load time and increases engagement.

Ensure all critical content is available without JavaScript.

Use structured data to help search engines understand your content.

Regularly monitor your site's indexing status in Google Search Console.

These strategies help maintain your site's visibility in search engine results, ensuring that lazy loading doesn't negatively impact your SEO efforts.

Addressing Browser Compatibility Issues

While most modern browsers support lazy loading, some older versions may not. To ensure compatibility, consider using a polyfill or fallback solutions for browsers that don't support lazy loading natively.

By addressing these compatibility issues, you can provide a consistent experience for all users, regardless of their browser choice. Regularly updating your site and testing on different browsers can help you identify and resolve any issues that arise.

Troubleshooting Loading Delays

Even with lazy loading implemented, you might encounter loading delays. This often happens when elements are not optimized or when there are too many third-party scripts running on your site. To troubleshoot these issues, start by identifying the elements that are causing delays. Use tools like Google Chrome's Developer Tools to pinpoint these elements and analyze their loading times.

Once you've identified the culprits, consider compressing images, deferring non-essential scripts, and minimizing the use of third-party plugins. By doing so, you can significantly reduce loading times and improve the overall performance of your website.

The Future of Lazy Loading in Web Development

Lazy loading is set to become an integral part of web development as websites continue to grow in complexity and size. With the increasing demand for faster and more efficient websites, lazy loading offers a practical solution to enhance user experience without compromising on content richness.

"Lazy loading is not just a trend; it's a necessity for modern web development. As websites evolve, so do the techniques we use to optimize them."

As more developers recognize the benefits of lazy loading, we can expect to see advancements in browser support and new tools that make implementation even easier. This evolution will ensure that lazy loading remains a vital component of web optimization strategies.

Emerging Technologies that Support Lazy Loading

Several emerging technologies are poised to enhance lazy loading capabilities. For instance, progressive web apps (PWAs) and server-side rendering (SSR) can work alongside lazy loading to deliver content more efficiently. PWAs offer offline capabilities and faster load times, while SSR ensures that content is rendered on the server, reducing the load on the client's device.

Additionally, advances in artificial intelligence and machine learning could further optimize lazy loading by predicting user behavior and preloading content accordingly. These technologies have the potential to revolutionize how we approach web performance optimization.

The Growing Importance of Mobile Optimization

As mobile usage continues to rise, optimizing websites for mobile devices has become more critical than ever. Lazy loading plays a crucial role in this optimization by reducing data usage and improving load times on mobile networks.

By implementing lazy loading, you can ensure that your mobile users have a seamless experience, regardless of their network conditions. This is particularly important for users in regions with slower internet speeds, where every byte counts.

Frequently Asked Questions

Lazy loading is a powerful tool, but it can also raise questions for those unfamiliar with its implementation. Here are some common questions and answers to help you better understand lazy loading and its impact on your website.

These insights will help you make informed decisions about implementing lazy loading on your site and address any concerns you may have.

Humans are not perfectly vigilant

I'm on tour with my new, nationally bestselling novel The Bezzle! Catch me in BOSTON with Randall "XKCD" Munroe (Apr 11), then PROVIDENCE (Apr 12), and beyond!

Here's a fun AI story: a security researcher noticed that large companies' AI-authored source-code repeatedly referenced a nonexistent library (an AI "hallucination"), so he created a (defanged) malicious library with that name and uploaded it, and thousands of developers automatically downloaded and incorporated it as they compiled the code:

https://www.theregister.com/2024/03/28/ai_bots_hallucinate_software_packages/

These "hallucinations" are a stubbornly persistent feature of large language models, because these models only give the illusion of understanding; in reality, they are just sophisticated forms of autocomplete, drawing on huge databases to make shrewd (but reliably fallible) guesses about which word comes next:

https://dl.acm.org/doi/10.1145/3442188.3445922

Guessing the next word without understanding the meaning of the resulting sentence makes unsupervised LLMs unsuitable for high-stakes tasks. The whole AI bubble is based on convincing investors that one or more of the following is true:

There are low-stakes, high-value tasks that will recoup the massive costs of AI training and operation;

There are high-stakes, high-value tasks that can be made cheaper by adding an AI to a human operator;

Adding more training data to an AI will make it stop hallucinating, so that it can take over high-stakes, high-value tasks without a "human in the loop."

These are dubious propositions. There's a universe of low-stakes, low-value tasks – political disinformation, spam, fraud, academic cheating, nonconsensual porn, dialog for video-game NPCs – but none of them seem likely to generate enough revenue for AI companies to justify the billions spent on models, nor the trillions in valuation attributed to AI companies:

https://locusmag.com/2023/12/commentary-cory-doctorow-what-kind-of-bubble-is-ai/

The proposition that increasing training data will decrease hallucinations is hotly contested among AI practitioners. I confess that I don't know enough about AI to evaluate opposing sides' claims, but even if you stipulate that adding lots of human-generated training data will make the software a better guesser, there's a serious problem. All those low-value, low-stakes applications are flooding the internet with botshit. After all, the one thing AI is unarguably very good at is producing bullshit at scale. As the web becomes an anaerobic lagoon for botshit, the quantum of human-generated "content" in any internet core sample is dwindling to homeopathic levels:

https://pluralistic.net/2024/03/14/inhuman-centipede/#enshittibottification

This means that adding another order of magnitude more training data to AI won't just add massive computational expense – the data will be many orders of magnitude more expensive to acquire, even without factoring in the additional liability arising from new legal theories about scraping:

https://pluralistic.net/2023/09/17/how-to-think-about-scraping/

That leaves us with "humans in the loop" – the idea that an AI's business model is selling software to businesses that will pair it with human operators who will closely scrutinize the code's guesses. There's a version of this that sounds plausible – the one in which the human operator is in charge, and the AI acts as an eternally vigilant "sanity check" on the human's activities.

For example, my car has a system that notices when I activate my blinker while there's another car in my blind-spot. I'm pretty consistent about checking my blind spot, but I'm also a fallible human and there've been a couple times where the alert saved me from making a potentially dangerous maneuver. As disciplined as I am, I'm also sometimes forgetful about turning off lights, or waking up in time for work, or remembering someone's phone number (or birthday). I like having an automated system that does the robotically perfect trick of never forgetting something important.

There's a name for this in automation circles: a "centaur." I'm the human head, and I've fused with a powerful robot body that supports me, doing things that humans are innately bad at.

That's the good kind of automation, and we all benefit from it. But it only takes a small twist to turn this good automation into a nightmare. I'm speaking here of the reverse-centaur: automation in which the computer is in charge, bossing a human around so it can get its job done. Think of Amazon warehouse workers, who wear haptic bracelets and are continuously observed by AI cameras as autonomous shelves shuttle in front of them and demand that they pick and pack items at a pace that destroys their bodies and drives them mad:

https://pluralistic.net/2022/04/17/revenge-of-the-chickenized-reverse-centaurs/

Automation centaurs are great: they relieve humans of drudgework and let them focus on the creative and satisfying parts of their jobs. That's how AI-assisted coding is pitched: rather than looking up tricky syntax and other tedious programming tasks, an AI "co-pilot" is billed as freeing up its human "pilot" to focus on the creative puzzle-solving that makes coding so satisfying.

But an hallucinating AI is a terrible co-pilot. It's just good enough to get the job done much of the time, but it also sneakily inserts booby-traps that are statistically guaranteed to look as plausible as the good code (that's what a next-word-guessing program does: guesses the statistically most likely word).

This turns AI-"assisted" coders into reverse centaurs. The AI can churn out code at superhuman speed, and you, the human in the loop, must maintain perfect vigilance and attention as you review that code, spotting the cleverly disguised hooks for malicious code that the AI can't be prevented from inserting into its code. As "Lena" writes, "code review [is] difficult relative to writing new code":

https://twitter.com/qntm/status/1773779967521780169

Why is that? "Passively reading someone else's code just doesn't engage my brain in the same way. It's harder to do properly":

https://twitter.com/qntm/status/1773780355708764665

There's a name for this phenomenon: "automation blindness." Humans are just not equipped for eternal vigilance. We get good at spotting patterns that occur frequently – so good that we miss the anomalies. That's why TSA agents are so good at spotting harmless shampoo bottles on X-rays, even as they miss nearly every gun and bomb that a red team smuggles through their checkpoints:

https://pluralistic.net/2023/08/23/automation-blindness/#humans-in-the-loop

"Lena"'s thread points out that this is as true for AI-assisted driving as it is for AI-assisted coding: "self-driving cars replace the experience of driving with the experience of being a driving instructor":

https://twitter.com/qntm/status/1773841546753831283

In other words, they turn you into a reverse-centaur. Whereas my blind-spot double-checking robot allows me to make maneuvers at human speed and points out the things I've missed, a "supervised" self-driving car makes maneuvers at a computer's frantic pace, and demands that its human supervisor tirelessly and perfectly assesses each of those maneuvers. No wonder Cruise's murderous "self-driving" taxis replaced each low-waged driver with 1.5 high-waged technical robot supervisors:

https://pluralistic.net/2024/01/11/robots-stole-my-jerb/#computer-says-no

AI radiology programs are said to be able to spot cancerous masses that human radiologists miss. A centaur-based AI-assisted radiology program would keep the same number of radiologists in the field, but they would get less done: every time they assessed an X-ray, the AI would give them a second opinion. If the human and the AI disagreed, the human would go back and re-assess the X-ray. We'd get better radiology, at a higher price (the price of the AI software, plus the additional hours the radiologist would work).

But back to making the AI bubble pay off: for AI to pay off, the human in the loop has to reduce the costs of the business buying an AI. No one who invests in an AI company believes that their returns will come from business customers to agree to increase their costs. The AI can't do your job, but the AI salesman can convince your boss to fire you and replace you with an AI anyway – that pitch is the most successful form of AI disinformation in the world.

An AI that "hallucinates" bad advice to fliers can't replace human customer service reps, but airlines are firing reps and replacing them with chatbots:

https://www.bbc.com/travel/article/20240222-air-canada-chatbot-misinformation-what-travellers-should-know

An AI that "hallucinates" bad legal advice to New Yorkers can't replace city services, but Mayor Adams still tells New Yorkers to get their legal advice from his chatbots:

https://arstechnica.com/ai/2024/03/nycs-government-chatbot-is-lying-about-city-laws-and-regulations/

The only reason bosses want to buy robots is to fire humans and lower their costs. That's why "AI art" is such a pisser. There are plenty of harmless ways to automate art production with software – everything from a "healing brush" in Photoshop to deepfake tools that let a video-editor alter the eye-lines of all the extras in a scene to shift the focus. A graphic novelist who models a room in The Sims and then moves the camera around to get traceable geometry for different angles is a centaur – they are genuinely offloading some finicky drudgework onto a robot that is perfectly attentive and vigilant.

But the pitch from "AI art" companies is "fire your graphic artists and replace them with botshit." They're pitching a world where the robots get to do all the creative stuff (badly) and humans have to work at robotic pace, with robotic vigilance, in order to catch the mistakes that the robots make at superhuman speed.

Reverse centaurism is brutal. That's not news: Charlie Chaplin documented the problems of reverse centaurs nearly 100 years ago:

https://en.wikipedia.org/wiki/Modern_Times_(film)

As ever, the problem with a gadget isn't what it does: it's who it does it for and who it does it to. There are plenty of benefits from being a centaur – lots of ways that automation can help workers. But the only path to AI profitability lies in reverse centaurs, automation that turns the human in the loop into the crumple-zone for a robot:

🎄💾🗓️ Day 11: Retrocomputing Advent Calendar - The SEL 840A🎄💾🗓️

Systems Engineering Laboratories (SEL) introduced the SEL 840A in 1965. This is a deep cut folks, buckle in. It was designed as a high-performance, 24-bit general-purpose digital computer, particularly well-suited for scientific and industrial real-time applications.

Notable for using silicon monolithic integrated circuits and a modular architecture. Supported advanced computation with features like concurrent floating-point arithmetic via an optional Extended Arithmetic Unit (EAU), which allowed independent arithmetic processing in single or double precision. With a core memory cycle time of 1.75 microseconds and a capacity of up to 32,768 directly addressable words, the SEL 840A had impressive computational speed and versatility for its time.

Its instruction set covered arithmetic operations, branching, and program control. The computer had fairly robust I/O capabilities, supporting up to 128 input/output units and optional block transfer control for high-speed data movement. SEL 840A had real-time applications, such as data acquisition, industrial automation, and control systems, with features like multi-level priority interrupts and a real-time clock with millisecond resolution.

Software support included a FORTRAN IV compiler, mnemonic assembler, and a library of scientific subroutines, making it accessible for scientific and engineering use. The operator’s console provided immediate access to registers, control functions, and user interaction! Designed to be maintained, its modular design had serviceability you do often not see today, with swing-out circuit pages and accessible test points.

And here's a personal… personal computer history from Adafruit team member, Dan…

== The first computer I used was an SEL-840A, PDF:

I learned Fortran on it in eight grade, in 1970. It was at Oak Ridge National Laboratory, where my parents worked, and was used to take data from cyclotron experiments and perform calculations. I later patched the Fortran compiler on it to take single-quoted strings, like 'HELLO', in Fortran FORMAT statements, instead of having to use Hollerith counts, like 5HHELLO.

In 1971-1972, in high school, I used a PDP-10 (model KA10) timesharing system, run by BOCES LIRICS on Long Island, NY, while we were there for one year on an exchange.

This is the front panel of the actual computer I used. I worked at the computer center in the summer. I know the fellow in the picture: he was an older high school student at the time.

The first "personal" computers I used were Xerox Alto, Xerox Dorado, Xerox Dandelion (Xerox Star 8010), Apple Lisa, and Apple Mac, and an original IBM PC. Later I used DEC VAXstations.

Dan kinda wins the first computer contest if there was one… Have first computer memories? Post’em up in the comments, or post yours on socialz’ and tag them #firstcomputer #retrocomputing – See you back here tomorrow!

[cerulity]

About Me

thought i would make this post because why not

My online pseudonym is Cerulity32K, casually Cerulity. Though, my preferred name is Kali, and my alternate username is Kali the Catgirl.

Though my mental conditions are mild, I do have ADHD (inattentive) and am seeking an autism evaluation. I am also trans (she/they).

But let's get to the good stuff. I excel in computing, especially low-level stuff and graphics (webdev scares me) and math, advanced functions, calculus and linear algebra being the most useful to me. I like to intersect math and computing, and it leads to some pretty fun results, especially when dealing with graphics. My main languages are Rust, C, C++, CUDA, C#, and Python, though I am trying to understand Assembly for a few systems (my laptop [x86_64], NES [6502], and the Atari 2600 [6507]). The main libraries I go to are Raylib and Macroquad for 2D games, and for 3D I go for wgpu, Vulkan, or OpenGL, though wgpu may be the main one I use from now on.

I also do music. My favourite types of music are either loud, distorted songs (FREE.99), literally noise (Portal 2 OST), or electronic-jazz fusion (Creo). I also sometimes make music. It's usually remixes or covers, as I suck at melody crafting, but I have made a couple original songs. I specialize in industrial chiptune and what I like to call "rustcore". My two music environments are LMMS and Furnace, though the latter is the main one I use nowadays.

My favourite game genres are automation, puzzle, and platformer. Factorio, Exapunks, and Celeste are my favourites in those genres respectively.

Other than that, I like to do procedural or subdiv modelling in Blender.

All in all, I'm just a software catgirl :3

Tools of the Trade for Learning Cybersecurity

I created this post for the Studyblr Masterpost Jam, check out the tag for more cool masterposts from folks in the studyblr community!

Cybersecurity professionals use a lot of different tools to get the job done. There are plenty of fancy and expensive tools that enterprise security teams use, but luckily there are also lots of brilliant people writing free and open-source software. In this post, I'm going to list some popular free tools that you can download right now to practice and learn with.

In my opinion, one of the most important tools you can learn how to use is a virtual machine. If you're not already familiar with Linux, this is a great way to learn. VMs are helpful for separating all your security tools from your everyday OS, isolating potentially malicious files, and just generally experimenting. You'll need to use something like VirtualBox or VMWare Workstation (Workstation Pro is now free for personal use, but they make you jump through hoops to download it).

Below is a list of some popular cybersecurity-focused Linux distributions that come with lots of tools pre-installed:

Kali is a popular distro that comes loaded with tools for penetration testing

REMnux is a distro built for malware analysis

honorable mention for FLARE-VM, which is not a VM on its own, but a set of scripts for setting up a malware analysis workstation & installing tools on a Windows VM.

SANS maintains several different distros that are used in their courses. You'll need to create an account to download them, but they're all free:

Slingshot is built for penetration testing

SIFT Workstation is a distro that comes with lots of tools for digital forensics

These distros can be kind of overwhelming if you don't know how to use most of the pre-installed software yet, so just starting with a regular Linux distribution and installing tools as you want to learn them is another good choice for learning.

Free Software

Wireshark: sniff packets and explore network protocols

Ghidra and the free version of IDA Pro are the top picks for reverse engineering

for digital forensics, check out Eric Zimmerman's tools - there are many different ones for exploring & analyzing different forensic artifacts

pwntools is a super useful Python library for solving binary exploitation CTF challenges

CyberChef is a tool that makes it easy to manipulate data - encryption & decryption, encoding & decoding, formatting, conversions… CyberChef gives you a lot to work with (and there's a web version - no installation required!).

Burp Suite is a handy tool for web security testing that has a free community edition

Metasploit is a popular penetration testing framework, check out Metasploitable if you want a target to practice with

SANS also has a list of free tools that's worth checking out.

Programming Languages

Knowing how to write code isn't a hard requirement for learning cybersecurity, but it's incredibly useful. Any programming language will do, especially since learning one will make it easy to pick up others, but these are some common ones that security folks use:

Python is quick to write, easy to learn, and since it's so popular, there are lots of helpful libraries out there.

PowerShell is useful for automating things in the Windows world. It's built on .NET, so you can practically dip into writing C# if you need a bit more power.

Go is a relatively new language, but it's popular and there are some security tools written in it.

Rust is another new-ish language that's designed for memory safety and it has a wonderful community. There's a bit of a steep learning curve, but learning Rust makes you understand how memory bugs work and I think that's neat.

If you want to get into reverse engineering or malware analysis, you'll want to have a good grasp of C and C++.

Other Tools for Cybersecurity

There are lots of things you'll need that aren't specific to cybersecurity, like:

a good system for taking notes, whether that's pen & paper or software-based. I recommend using something that lets you work in plain text or close to it.

general command line familiarity + basic knowledge of CLI text editors (nano is great, but what if you have to work with a system that only has vi?)

familiarity with git and docker will be helpful

There are countless scripts and programs out there, but the most important thing is understanding what your tools do and how they work. There is no magic "hack this system" or "solve this forensics case" button. Tools are great for speeding up the process, but you have to know what the process is. Definitely take some time to learn how to use them, but don't base your entire understanding of security on code that someone else wrote. That's how you end up as a "script kiddie", and your skills and knowledge will be limited.

Feel free to send me an ask if you have questions about any specific tool or something you found that I haven't listed. I have approximate knowledge of many things, and if I don't have an answer I can at least help point you in the right direction.

Looking for some advice for shifting my music collection away from Spotify?

I have, over the last decade and a half or so, been building up my big music library on Spotify. I am now wanting to leave Spotify behind thanks to it's slowly encroaching enshittification and other problems.

Unfortunately, due to how long I’ve been there, my main playlist alone is at just shy of 1900 tracks, and that's before i get onto other playlists. This makes the moving quite a mammoth undertaking, and spotify seems designed to make escaping as hard as possible.

So I’m looking for suggestions on software that can get me going on this.

Main things I'm looking for

Being able to automate recreating my main playlist with local files Bonus points if it can do placeholders for missing tracks. (I have my song list in csv form, so hopefully that'd help.)

Being able to automatically sync the playlist and song files to my android phone. (Over LAN probably?)

Any help would be super appreciated.
