You’ve had problems with files. Probably due to their file extensions. Let’s say you wanted the last three characters to determine the file type. You ask some people questions about it.

You search for code to find the last three characters. Your coworkers probably have some suggestions, so you ask them as well.

You’re stuck on your solution, without looking back at the problem.

You’ve got into the XY problem. Let’s go into the details of it.

What’s the XY Problem?

The XY problem is asking about your attempted Y solution. You should ask about actual X problem.

There are Git beginners. There is Oh My Git! A game to learn Git today.

This is an interactive game, which learns you the basics of Git. How? By visualizing all the Git actions, the Git newbie applies.

Here’s how the Oh My Git works. And my personal opinion on each game part.

How Oh My Git! works?

You can pick from the list of possible Git actions. You pick one, and it opens a new window. This is where the actual learning happens. You can drag and drop the Git action, and the game will show how it works.

If you get one percent better each day for one year, you’ll end up thirty-seven times better by the time you’re done. — James Clear

Doing small improvements makes all the difference. You could do a thorough review of the code, stop the bug, and free up more time to spend on Medium.

You see yourself pulling and merging branches all the time? Automate. Develop scripts, and free up more time. Time to use for your wellbeing.

Here are some of the tips I’ve applied to be more productive.

1. Improve soft skills

Working with testers is hard. I’ve learned that the hard way…

Wrong beliefs cost. They cost a lot. A lot of time, effort, and money.

Assuming you have a good address entry process. What if you have issues with address entry?

4 in 10 shoppers abandon their cart if there’s an issue with address entry⁵.

Assuming you have a simple checkout process. What if you have a complex checkout?

11% of cart abandoners leave because the checkout process was too complex.

This is the tip of the iceberg. More unknown stats exist. All because of wrong assumptions.

Here are the 3 common myths of software engineering. These will help you avoid…

Good Java practices improve software quality.

Here’s how developers work. The deadline is near — rush to raise the PR. PR which isn’t the best. We have more time — we fill it with work. Work which isn’t the best.

As Java developers, we should all strive to better code. This saves our job, business, and brings profit.

Bad practices happen, in the interest of time. But we should converge to better practices.

Here are the 3 practices Java developers should know.

1. Error handling

Create custom exceptions. Bring more domain information into your errors. Don’t catch generic exceptions. …

SAP Hybris. SAP Commerce Cloud.

Why is it good nowadays? Why is it worth doing Hybris?

High traffic, high revenue sites, enterprise. They all use Hybris. To solve their e-commerce problems. Look at the stats for Hybris.

We all know Git. What we don’t know? What lies beneath, and all the Git intricacies.

Recently, there was a fix for the git clonefeature. You could execute malicious code while cloning. Exploit targets vulnerabilities of delayed checkout.

Let’s go into detail.

* CVE-2021-21300:
  On case-insensitive filesystems, with support for symbolic links,
  if Git is configured globally to apply delay-capable clean/smudge
  filters (such as Git LFS), Git could be fooled into running
  remote code during a clone.[1]

Case-insensitive filesystems are NTFS, HFS+ or APFS. All these are currently used in macOS, Linux*, and Windows.

Making this an issue for the…

Code review impacts software quality.³ Participation in code reviews reduces the risk of bugs.³

Good review leads to fewer bugs, more expertise, and knowledge transfer.

On average, frequent code reviewers, write better code than others. That’s because they know more, and they see more code.

Your team is only as good as your weakest reviewer. — Joel Kemp

Here’s how to review Java code better.

How to review for security

Secure your services. Create robust services. Expect unexpected behavior. Create fallback for all errors.

Don’t log confidential information. Credit card information, permissions, and other sensitive data.

Don’t create exceptions holding sensitive data. This exposes sensitive…
