Revisiting MCSA Study Materials

Having read the MCSA study material over a year ago, I’ve decided it’s time for a second read. Despite using SQL daily at work, I'm still not confident about sitting for the exam.

Committing to the Reading

With three books totaling around 2,000 pages, I’ve mapped out a plan to tackle this material. At a pace of 20 pages per hour, I’m looking at approximately 100 hours of reading time. It feels daunting, but I’m committed to getting through it all to solidify my knowledge and boost my confidence before the exam.

Sony MDR-ZX100 vs ZX-110 vs ZX310 Series Headphones

Sony ZX Series Headphones Review: A Budget-Friendly Sound Choice If you’re on the hunt for budget-friendly headphones with decent quality, the Sony ZX Series is definitely worth considering. I happen to own several models from the lineup: ZX-100 ZX-110 ZX-310 Let’s dive into how they compare in terms of build quality, cost, specs, sound, and overall value. Build Quality: ZX-310 Takes the Lead The Sony ZX series headphones primarily feature a durable plastic construction. My ZX-100 has lasted over 2½ years, enduring countless tosses into my backpack and car without any issues. However, the lower-end ZX-100 and ZX-110 models have a significant downside: poor-quality earpads. Over time, these earpads disintegrate, leaving vinyl flakes that stick to your hair and ears. The ZX-310, on the other hand, comes with upgraded earpads that don’t suffer from this problem, making them a clear winner in the build department. Cost Comparison: ZX-100/110 Wins for Affordability While the ZX-310 model co

Casio G-Shock 5600 vs 6900 vs 9000

G-Shock Preferences and Favorites After trying out several G-Shock models, I've developed a better sense of the specific features and design elements I appreciate most. While features are always a plus, my main priority is size . Here's how some of the models I've tried stack up. Size Preference: DW-5600 Series For overall size, the DW-5600 series stands out as a favorite due to its compact, comfortable form. It’s slim, lightweight, and fits well on my wrist without being too bulky. Although the 6900 series provides the benefit of a well-placed front illumination button, the 5600 remains the ideal size for everyday wear. Best Compromise: G9000 Mudman Series If I had to choose a balanced option between size, comfort, and functionality, the G9000 Mudman series would be it. The buttons are slightly tough to press, but the layout and form factor resonate with what I prefer in a G-Shock. Despite having different module versions (GLX, G, and DW), I find that these models offe

Eton Microlink FR160 Radio -- Sticky Residue

Eton Microlink FR160 Handcrank Radio Review I bought an Eton Microlink FR160 handcrank radio for my emergency kit a few years ago, and it’s been great overall. However, there’s one significant issue I've encountered. Sticky Residue Problem Over time, a sticky residue developed on the radio's external surface, which was driving me nuts. At first, I thought there was something wrong with the device. Solution Fortunately, I researched the problem online and discovered that Eton radios are coated with a substance designed to make them easier to grip. Unfortunately, this coating degrades over time and turns into a sticky mess. To resolve the issue, I used isopropyl alcohol and cotton balls to clean most of the gunk. While some paint may have been lost in the process, at least the radio is no longer sticky.
