Removing .DS_Store Files from Git Repositories

If you are a Mac user who also uses Git, you might accidentally commit a .DS_Store file. This could confuse your Windows colleagues, who may wonder what these files do and why you've committed them.

First, what is a .DS_Store file? DS stands for Desktop Services, and these files are used by Macs to determine how to display folders when you open them. For example, they store custom attributes like the positions of icons. These files are created and maintained by the Finder application on a Mac, and are normally hidden.

These .DS_Store files are not useful to Windows users and do not need to be committed to your GitHub repository. To remove existing .DS_Store files from your repository, run the following command:

    find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch

Afterwards, commit the changes to remove those files and push to the remote repository. To prevent these files from being added again, edit your .gitignore file and add the following line:

    .DS_Store

Doing so will address any concerns your colleagues may have.

Removing .DS_Store Files from Git Repositories

Welcome back to another episode of Continuous Improvement, the podcast where we discuss tips and tricks for enhancing your productivity and problem-solving abilities. I'm your host, Victor, and in today's episode, we'll be addressing a common issue faced by Mac users who also use Git.

If you're a Mac user who has accidentally committed a .DS_Store file, you might be wondering why this is a problem and how it can confuse your Windows colleagues. Well, fear not, because today I'll be sharing some insights on what these files are and how you can avoid committing them.

So, what exactly is a .DS_Store file? The 'DS' in .DS_Store stands for Desktop Services, and these files are used by Macs to determine how to display folders when you open them. They store custom attributes such as the positions of icons and are created and maintained by the Finder application on a Mac. Normally, these files remain hidden from view.

However, for Windows users, these .DS_Store files aren't useful and can cause confusion when they find them in a Git repository. Fortunately, there's a straightforward solution to remove these files from your repository.

To remove existing .DS_Store files, you'll need to run a simple command in your terminal. Here's what you need to type:

    find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch

This command will find all the .DS_Store files in your repository and remove them. Remember to commit the changes and push them to your remote repository to ensure these files are permanently removed.

But how do you prevent .DS_Store files from being added again in the future? It's simple! You just need to edit your .gitignore file and add the following line:

    .DS_Store

By adding this line to your .gitignore file, you're telling Git to ignore any .DS_Store files that are present in your repository.

By following these steps, you'll address any concerns your Windows colleagues may have about these files and maintain a cleaner, more organized Git repository.

That concludes today's episode of Continuous Improvement. I hope you found this information valuable and will be able to implement these steps in your own Git workflow. Thank you for tuning in, and remember to keep striving for continuous improvement!

從 Git 倉庫中移除 .DS_Store 文件

如果你是一個同時使用 Mac 和 Git 的用戶，你可能會無意間提交 .DS_Store 文件。這可能會讓你的 Windows 同事感到困惑，他們可能不清楚這些文件的用途，也不明白你為何要提交它們。

首先，什麼是 .DS_Store 文件？ DS 代表桌面服務（Desktop Services），這些文件被 Mac 用來確定當你打開它們時如何顯示文件夾。例如，它們存儲自定義屬性，如圖標的位置。這些文件由 Mac 的 Finder 應用程序創建並維護，並且通常是隱藏的。

這些 .DS_Store 文件對 Windows 用戶無益，也不需要提交到你的 GitHub 倉庫。要從你的倉庫中移除現有的 .DS_Store 文件，執行以下命令：

    find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch

然後，提交更改以移除這些文件，並推送到遠程倉庫。為了防止這些文件再次被添加，編輯你的 .gitignore 文件，並添加以下行：

    .DS_Store

這樣做將避免你的同事產生任何疑慮。

Ignoring Already Modified Files in Git

I've encountered a rare scenario where a file has been modified, but I don't want to commit this change to Git. There are various methods to achieve this, such as using a .gitignore file. However, this approach doesn't work if the file is already being tracked.

The solution is to manually ignore the file by executing the following command:

    git update-index --assume-unchanged <file path>

To start tracking the file again, you can revert this action by using the following command:

    git update-index --no-assume-unchanged <file path>

Ignoring Already Modified Files in Git

Welcome to the Continuous Improvement podcast, where we explore tips, tricks, and strategies for enhancing your personal and professional growth. I'm your host, Victor, and in today's episode, we'll be discussing how to handle a rare scenario in Git when you want to modify a file without committing the changes.

Have you ever found yourself in a situation where you need to modify a file, but you don't want to include those changes in your Git commit? Perhaps you're experimenting with some code, or you have local configuration changes that are specific to your environment. Well, there's actually a solution for this, and today we'll be diving into it.

Now, typically, when you want to exclude a file or a directory from being tracked by Git, you would use the .gitignore file. However, this method won't work if the file is already being tracked. So what should we do in such cases?

The solution lies in the git update-index command. By using this command, we can manually ignore specific files without modifying our .gitignore file. Let me walk you through the process.

To ignore a file and prevent it from being committed, you need to execute the following command in your Git terminal:

    git update-index --assume-unchanged <file path>

Let's break this down. --assume-unchanged is the flag used to tell Git to ignore the file, and <file path> refers to the specific file you want to exclude. By executing this command, Git will no longer consider any changes made to that file when you're committing your code.

Now, what if you want to start tracking the file again and include its changes in future commits? No worries. You can simply revert this action by using the following command:

    git update-index --no-assume-unchanged <file path>

So, in essence, this command undoes the ignore action and allows Git to track any future modifications you make to the file.

It's important to note that while using --assume-unchanged, if you make any changes to the file and try to switch branches, Git might prompt you to either stash or discard those changes. So, be cautious and ensure you're aware of the potential consequences.

And there you have it - a simple and effective way to modify a file without committing the changes to Git. Remember to use the git update-index command with the --assume-unchanged flag to ignore the file, and the --no-assume-unchanged flag to revert it.

I hope you found this tip useful, and if you have any questions or need further clarification, feel free to reach out. The power of Git lies in its flexibility, and it's always good to know these tricks that can make your version control workflow smoother.

在Git中忽略已修改的文件

我遇到了一種罕見的情況，一個文件已經被修改，但是我不想將這個變更提交給Git。有各種方法可以實現這一點，比如使用.gitignore文件。然而，如果文件已經被追蹤，這種方法就不起作用。

解決方案是通過執行以下命令來手動忽略文件：

    git update-index --assume-unchanged <文件路徑>

要再次追蹤文件，您可以通過使用以下命令來撤消此操作：

    git update-index --no-assume-unchanged <文件路徑>

Find and Kill Processes Locking Specific Ports on a Mac

Problem: Sometimes, when you start a local Node.js server, it may continue running in the background. If you try to start the server again, you may encounter an error indicating that the port (e.g., 8080) is already in use and locked:

    throw er; // Unhandled 'error' event
    Error: listen EADDRINUSE 127.0.0.1:8080

Solution: You can use the lsof command to identify the process locking the port:

    lsof -n -i4TCP:8080

Alternatively, you can replace 8080 with the specific port number you want to investigate. This will display a list of processes currently using that port. Identify the process you wish to terminate (for example, node running with PID 6709) and execute the following command to kill it:

    kill -9 <PID>

Finally, restart your server. It should run normally once the port has been freed.

Find and Kill Processes Locking Specific Ports on a Mac

Welcome to "Continuous Improvement," the podcast where we explore tips, tricks, and solutions for overcoming development hurdles. I'm your host, Victor, and in today's episode, we'll be discussing a common issue many developers encounter while working with Node.js servers: the dreaded port lock error.

Have you ever tried to start a local Node.js server only to find out that the port you want to use is already in use and locked? It can be quite frustrating, but fear not, because today we have a solution for you.

The problem occurs when you try to start your server and receive an error message that says, "Error: listen EADDRINUSE..." followed by the IP address and port number. But worry not, there's a way to identify which process is locking that port.

One method is to utilize the command-line tool called lsof. Simply open your terminal, and type in lsof -n -i4TCP:<port>. Replace <port> with the specific port number you want to investigate, such as 8080.

Once you execute this command, you'll be provided with a list of processes currently using that port. Take note of the process you wish to terminate. For example, you might see a process like node running with a PID (Process ID) of 6709.

Now comes the moment of truth. Execute the following command to kill the process and free up the locked port: kill -9 <PID>. Remember to replace <PID> with the actual Process ID you want to terminate, in this case, 6709.

Once you've successfully terminated the process, you're almost out of the woods. Now you can restart your server, and it should run normally without encountering the port lock error.

And there you have it! A simple yet effective solution for tackling the port lock issue in Node.js. Remember to use the lsof command to identify the process locking the port, and then terminate it using kill -9 <PID>.

That concludes today's episode of "Continuous Improvement". I hope this solution will help you overcome any port-related obstacles you may encounter in your development journey. Thanks for listening, and until next time, keep striving for continuous improvement in your coding endeavors.

在 Mac 上尋找並終止鎖定特定端口的進程

問題：有時候，當您啟動一個本地 Node.js 服務器時，它可能會繼續在後台運行。如果您嘗試再次啟動服務器，您可能會遇到一個錯誤，指出端口（例如，8080）已經在使用中並被鎖定：

    throw er; // Unhandled 'error' event
    Error: listen EADDRINUSE 127.0.0.1:8080

解決方案：您可以使用 lsof 命令來識別鎖定端口的進程：

    lsof -n -i4TCP:8080

或者，您可以將 8080 替換為您想要調查的特定端口號。這將顯示當前使用該端口的進程列表。識別您希望終止的進程（例如，正在運行的 node 與 PID 6709）並執行以下命令來將其殺死：

    kill -9 <PID>

最後，重新啟動您的服務器。一旦端口被釋放，它應該可以正常運行。

How to Work with a Product Manager as a Software Engineer

As a software engineer, I know how it feels to work with product managers. With years of experience, I've encountered fantastic Product Managers (PMs) as well as some less-than-ideal ones. Every day, I collaborate with PMs, and I understand the challenges that can arise, particularly when the relationship is strained. In this blog post, I'll offer advice on how to work effectively with a PM as a software engineer.

Two primary difficulties can arise when working with PMs. The first issue is that a PM without an engineering background may not understand the technical complexities you're dealing with, leading to a lack of mutual respect. Secondly, if a PM started their career as an engineer, it can be frustrating to hear them talk as if they fully understand technical subjects like blockchains, big data, or artificial intelligence when they actually don't.

To bridge these gaps, soft skills and communication abilities are essential.

Common Pitfall 1: Technological Ignorance

The worst thing to hear from a PM is something like, "It's just a simple button. Are you sure you can't finish it in five minutes?" Such comments imply that the work is straightforward and that you are incompetent. But, creating even a simple button is not trivial. For example, Google's homepage search button is not just a "simple button." Various states like hover, click, double-click, and other factors like text localization, accessibility, and multiple screen widths must be considered.

Common Mistake 2: Misunderstanding Roles and Responsibilities

PMs are responsible for the product, but they are not your bosses. This misunderstanding can be especially prevalent in hierarchical organizational structures or where an outsourced vendor manages in-house PMs. Practicing methodologies like Scrum can help set boundaries and manage expectations. Frequent changes in requirements can be detrimental to the project, leading to non-reusable code, bugs, and technical debt.

Common Error 3: Lack of Clear Objectives

It can be frustrating when a PM has no clear vision and hasn't defined specific requirements. Engineers thrive on tackling challenges and require clear goals. Poorly defined requirements lead to a product that's hard to measure in terms of impact and success.

Final Thoughts

To navigate these issues successfully, here are my three recommendations:

1. Treat non-technical stakeholders with empathy and kindness, while educating them on the complexities of your work.
2. Understand that the PM is not your boss; collaborate and be willing to share credit for successes.
3. Stay informed about industry trends and be prepared to construct a persuasive argument when you think the requirements are flawed.

Remember, software development is a team sport. Like any team, success depends on effective communication, collaboration, and leadership to achieve a common goal.
