🧩 Keil µVision Installation Problem: Missing Compiler 5

It all started after I shared the Keil µVision installation manual with the students on 9 October 2025. Everything seemed fine at first, until our class session on 15 October 2025. When several students reported encountering the “missing compiler 5” error during program build.

At that time, I reviewed their installation steps one by one, but the issue persisted. It wasn’t immediately clear whether the error came from a missing ARM toolchain component, a corrupted setup, or path configuration in Keil µVision.

By 29 October 2025, after our follow-up class, I noticed the problem still hadn’t been fully resolved. Between teaching, project supervision, and updating other course materials, I decided to dedicate some time to recheck the installation sequence myself in the morning 30 October 2025.

After about 40 minutes of testing, troubleshooting, and re-verifying the installation paths, I finally found the root cause; and the correct fix for the missing compiler 5 error. During that time, I also updated the installation manual with the corrected steps.

However, I haven’t shared the updated manual in the class Telegram group yet. Only a partial explanation and end result. were posted there. To help students who needed a quick reference what they should achieve in the end while I continue refining the full document for clarity and completeness.

Until then, have fun in trouble shooting error in Keil µVision.

🖥️ “Old but Not Obsolete”: A Quick Fix on a Vintage Windows Vista PC

This moment was captured on the afternoon of 27 May 2025, right after an intern diploma student mentioned he couldn't figure out how to take a screenshot on a Windows Vista computer. Where it was connected to the CNC machine in the PCB lab.

It took me less than a minute to get the screenshot done. No command prompt needed, no complicated steps. Just good old knowledge and muscle memory from the days of floppy disks. As someone who began using computers in the pre-USB era and holds a degree in Computer Engineering, I couldn’t help but feel a little proud. Sometimes, experience really does speak for itself.

Apparently, even ChatGPT couldn’t provide the answer he needed. And like a friend of mine said: Well, ChatGPT wasn’t around in the ’90s.

This whole encounter reminded me of a phrase made iconic by Arnold Schwarzenegger in Terminator Genisys: “Old but not obsolete.”

Arnold used it to emphasize that even though something or someone that may be aging, they’re far from irrelevant. That line couldn’t be more fitting in moments like this.

Until then, here’s to keeping old skills sharp and remembering that sometimes, the most timeless tools are the ones we’ve carried the longest. 👨‍💻💾

📝 Editing PDF Documents with Adobe

On the morning of 22 September 2025, I tried editing a PDF using Adobe. And honestly, it made life so much easier. No more struggling with converting files or looking for free online tools that don’t always work.

It was definitely worth the money I spent on the app. Everything feels seamless, and being able to quickly make changes to PDF files as needed saves me a lot of time and stress.

Sometimes, the right tool really is worth the investment.

Sweetness Test of My Harum Manis Mango

Last noon of 9 October 2025, just able to finished testing the Brix level of my freshly harvested Harum Manis mango. And the reading came out between 17 to 18° Brix! That means it’s beautifully sweet and perfectly ripe, just as expected from this variety.

The flavor is rich, honey-like, and smooth. Truly worth all the effort and care spent nurturing the tree. Each bite tastes like a reward for months of watering, pruning, and waiting for the right moment to harvest.

However, it’s important to note that this sweetness level (17–18° Brix) is not diabetes-friendly (disclaimer). As it indicates a high natural sugar content.

So, while it’s a delight for mango lovers, those watching their blood sugar should enjoy it only in moderation.

Until the next harvest, here’s to the joy of growing, tasting, and celebrating your own fruits at home.

Morning Harvest: Harum Manis Mango from My Own Tree

In the morning of 8 October 2025, I spent some time harvesting fruits from my self-planted Harum Manis mango tree at home. And managed to pick four lovely mangoes.

The heaviest weigh 565.5 gm. Followed by 456.8 gm, 446.3 gm and 206.3 gm.
The shape isn’t as curvy as those from Perlis, but that’s understandable. I only have one Harum Manis tree, and there are no other Harum Manis trees nearby. So, cross-pollination with other mango varieties might have influenced the shape. The environment here in Johor, with its different climate compared to Perlis, could also be a contributing factor.

Still, the fruits turned out beautifully. They’re sweet, fragrant, and have smooth, clean skin. Free from the usual sticky sap or blemishes. Friends who saw the pictures even complimented how neat and healthy they looked. That definitely made me feel proud. It feels like all the care, time, and effort I put into tending this tree have truly paid off.

Regardless of the shape, the taste and quality are satisfying. Nothing beats the joy of harvesting your own home-grown mangoes.

Until then, happy harvesting to all who grow their own fruits at home! 🌼🥭

🌀 The Downside of Using an Ultra High-Speed Fan

Entry made on the noon of 3 July 2025.

So here’s something they don’t mention when you buy an ultra high-speed fan. When a hair getting trapped inside.

I noticed it yesterday, but only this morning did I manage to get a closer look and try removing it. It was a struggle. I’d say I only managed to pull out about 30% of the trapped hair so far. The design is super slim, which makes it nearly impossible to insert bending forceps or bending tweezers properly. I ended up using an earpick, which was oddly the most effective tool I had on hand. On top of the honeycomb hole noise reduction design. Which makes it impossible to clean through the back side.

Still experimenting with what tool works best for this particular portable fan model. It’s a little frustrating, but I guess it’s part of owning high-speed gadgets. With small design, big airflow, tight corners.

Also it does hurt very much when it accidentally falls on my feet after Zohor prayer of 4 July 2025. Fortunately it does not bruise my aging right feet.

Until then, have fun figuring out how to clean your ultra high-speed fan. If you’ve found a clever tool that works, I’d love to know!

Work setup after 6 pm

This is taken on the evening of 25 February 2025. Where I managed to stay back after 6 pm to finished up my work. This is the work setup look.

I am staying in the vecad lab common area. As I wanted to have other working environment to finished up my work. Where the submission is less than 5 days time.

I have to turn on my portable fan. Since the central air-conditioning turn off after 6 pm time daily. And since the common area do not have split unit, I have to resort by turning on my portable fan to cool myself down. And it is a good investment. Since the wind from the fan is sufficiently strong. Plus the fan is less noisy than my other model.

Until then, have fun in finishing up your work for submission.
