Man Page? Stack Overflow? Random Blog? Oh My!

When you are in need of command line tool documentation, how often do you read the man pages (the manual) as opposed to Googling your question until you find the Stack Overflow post with the answer? Let’s face it, the man pages are dense. They rarely contain useful examples, not to mention that nobody has time to sift through multiple pages of flags they’ll likely never utilize in their life. Too long, didn’t read.

The solution? A command line utility that spits out abbreviated help.

With tldr, looking up those FAQs is quick and painless.

When a device on your WiFi network (i.e. your computer or phone) communicates with the outside world, your router assigns it an IP address. It is important to understand that for each new connection to the outside world, the IP address assigned to the device by the router may change.

When you go to https://google.com, your computer makes an HTTP GET request, asking a Google server (IP address 8.8.8.8) for a webpage. That request goes through your router, to the Google server, back through your router, to your computer. In order for the router to know to which device in…

TL;DR — You don’t need an expensive online course!

Hi! My name is Quinn Vissak and I recently passed the AWS SAA exam! Not only is the Solutions Architect Associate certification well-regarded in the software industry, but learning the material is directly applicable to most software engineering roles. Whether you are seeking a way to distinguish yourself from your peers for a promotion, or looking to “hop”, the certification and the process of getting the certification will help further your career.

Having just studied and completed this test, it is my opinion that you don’t need tens of hours of structured online videos that may cost hundreds of dollars…

Former FBI negotiator Chris Voss’s Never Split the Difference — Negotiating as if your life depended on it is a transformation-inducing book that has the capability to enhance numerous aspects of your communication. Incorporating the negotiation tactics discussed by Voss into your daily life — including your job — will undoubtedly result in more desirable outcomes from your interactions.

A lot of my written communication as a software engineer occurs through pull requests. Admittedly, I don’t always convey my thoughts as intended. Even more problematic, sometimes a comment slips through my mental filter and I do convey my thoughts exactly…

TL;DR — Simplify your code with Docker Compose!

If you are dealing with more than one container in the same application, chances are they need to talk to each other, but have static IP addresses. The code for this looks terrible and requires at least a basic understanding of subnets. Static IP addresses also impede your ability to run more than one instance of your application on the same host.

To address this problem, Docker Compose (and vanilla Docker) by default uses an embedded DNS server to communicate within networks. It allows one to use the service name in the…

My girlfriend and I are huge fans of Kung Fu Tea — and their Taro Milk Tea in particular. Depending on the location, two drinks could cost anywhere from nine to fourteen dollars, which always left us craving more. Such an addiction is not sustainable.

Discovery through Trial and Error

It took about six attempts and consulting a couple of friends who have worked at various boba tea establishments to hack the perfect recipe. The recipes I found on the first page of Google were all different — water or heavy cream or sweetened condensed milk, boiled taro root or taro powder, sugar or simple…

TL;DR — Save time by automating lengthy processes

Git aliases are more than just shortening git commands — aliases in the gitconfig file grant you the ability to execute scripts! With this, daily tasks that used to take minutes can shrink to seconds.

Now, instead of opening a new tab in my browser, going to GitHub, finding the repository I just pushed to, creating a pull request, and finally selecting the target fork/branch, I created an alias. git pr executes a script that automatically opens a new tab in Google Chrome with a pull request from my working branch to…
