In this post, we will explore a small quirk of MacOS. The title should be self-explanatory but might not be so obvious to heavy GUI users. Let’s take a closer look into this seemingly-feature-not-bug behavior on MacOS.
Time Machine is a built-in tool on MacOS for performing partial or full system backup. Time Machine works by taking snapshots of the system and storing those snapshots at external storage devices connected to the machine. To restore the backup, another built-in tool named Migration Assistant is used. Both Time Machine and Migration Assistant are GUI tools. These built-in tools enable users to conveniently transfer or migrate the content of an old Mac, be it documents, user accounts and settings, to a new Mac.
A full backup created with Time Machine can be restored by Migration Assistant through simple GUI-based flow. The process of copying all files from old Mac to the new Mac handled by Migration Assistant is performed with minimum user intervention. This really saves the time compared to performing the data transfer or copying manually. Continue reading
Updating packages and apps on MacOS is usually a trivial task. There are several avenues available, depending on the personal preference and degree of familiarity with various tools available on Mac. Now consider a case for updating Node.js (and subsequently npm) on MacOS. What are the options?
tl;dr Updating Node.js with lightweight package manager such as
n is less error prone especially for older MacOS version
Let’s start by listing the options on our perusal.
Option 1: Download the installer from nodejs.org and install the binary
This option is ideal for the first installation. It is less ideal for update / version upgrade or if we want to maintain several nodejs versions on the machine. Continue reading
Excel on MacOS has its own quirk when dealing with CSV file. If you have a CSV file that is encoded with UTF-8 and contains entries in multibyte characters from East Asian languages such as Chinese, Japanese, Koreans, opening the file in Excel on MacOS may give you some surprise. Instead of showing the East Asian characters, Excel will display garbled characters.
Let us a run experiment to explain this case. We will use Node JS to create a CSV file, encode the file using UTF-8 and then try to open it using Excel on MacOS. Continue reading

If you are doing frontend development nowadays, you may have heard about ReactJS or may be actively using it in your projects. Introduced to the public five years ago, React has transformed into a library of choice for a lot of frontend developers that is easily certified by the enormous stars at its Github page (more than 100,000 stars). React was relicensed into MIT license almost a year ago, which only catapulted its popularity into a new high. The MIT license is a more commercial friendly license compared to the BSD + patents license that was previously used by React.
Creating a frontend project is easy with the help of scaffolding tools and boilerplates. Among the available choices is create-react-app, a React bootstrapping utility that takes care the laborious tasks of setting up a React project without much intervention about how the project should be structured. Given this nature, create-react-app is less assumed a boilerplate and more of a toolkit. Continue reading
Node JS has been gaining more popularity as the server-side runtime environment of choice these recent years. The asynchronous event-driven feature built into Node JS can be considered a killer feature that may flatter a system architect planning to build a high-performing server-side component serving HTTP webservice to the clients.
Node JS is cross-platform. The executable can run on major OSes that include Windows, GNU Linux, and Mac OS. Having a wide OS support further accelerates Node JS adoption within the server-side technology stack. Continue reading
