Autumn Breeze | 秋のそよ風 [Artwork]

Titled Autumn Breeze, this e-watercolour painting features the portrait of a fictional girl standing under (and slightly in front of) a tree branch with autumn leaves. She appears to be fidgeting with her long, brown hair with her left hand, while leaves fall and flow with subtle winds blowing to her right. Wearing a red-white T-shirt with denim shorts, her right hand holds a purse-like item, while looking slightly off to her right. She also has a Yuzu Tofu plush toy on her head.

Random drawings like this are an example of something that happens when excessive stress from school workload, exams, and the need to continue maintaining my apps, all overwhelm me.

Hopefully this attempt (#3) of drawing and painting an anime-girl-like character should be a significant improvement over previous attempts.

Also, featuring Yuzu Tofu from the Hannari Tofu series. Not sponsored, I just find it cute, and other tofus may appear too :)

Pushing to Production on a Friday

TL;DR: Do not ever do that (or whatever that’s equivalent), unless you’re willing to face potentially serious consequences like I did. Or at least, make sure you know what you’re doing.


Sit back, and relax. It’s going to be a long read.

If you’ve seen the large number of jokes about programming online, you would know that pushing an update on a Friday, or any day before taking a few days off for that matter, is highly risky. You’re making the bold assumption that your software will function just fine as soon as it’s onto your user’s hands. If one’s lucky, users would never notice anything has changed, aside from any possible UI changes said software may have. However, we are humans, and humans make mistakes. We aren’t perfect robots being able to code a perfect piece of software every single time… well at least at the time of writing, robots can’t write software yet. Bugs will slip by, regardless of how much QA and testing you’ve done with software. If it’s a serious issue, congrats! Anger is what users go by, contacting support, writing reviews till you can’t leave your chair.

Well, as both a high school student and an indie app developer, this still applies, but in a different way. Continue reading “Pushing to Production on a Friday”
