Got Questions?

We strive to make our daily exercises as concise and accessible as possible. You will need two things prior to signing up:

1. A web browser (Chrome, Edge, Firefox, or Safari)
2. A GitHub account
3. A Substack subscription

All of our exercises run in GitHub Codespaces so our users can focus on debugging to learn as much as possible. For more info on Codespaces please visit https://github.com/features/codespaces.

*** Please note, GitHub Codespaces are currently not supported on mobile devices.

We charge $49.99 per month for short concise exercises sent to your inbox Monday through Friday. Also included is 40 hours of GitHub Codespace usage per month. Enjoy the complete package for one low monthly price. No commitment, cancel anytime.

All you need is a web browser, GitHub account and a Substack membership and we take care of the rest. Substack accepts most major credit cards such as Visa, MasterCard, Discover, and American Express.

No, we allocate a Codespace upfront and work hard to put these daily emails together. Unlike most services, time and dedication goes into researching relevant algorithms and what is the best way at explaining the inner workings so that the most amount of audience members grasp the concepts. That being said, you can get a preview of past exercises over at Substack.

Not currently. Our pricing is as low as possible for the value we provide. Please feel free to drop us a message on the contact page if you are a student and would like to see this in the future.

Unfortunately, we cannot offer refunds for monthly subscriptions. Reason being, once members sign up, we create and allocate a Codespace for your GitHub account. If you wish not to be billed in the future, we recommend canceling your subscription at least 3 days in advance of the next billing cycle.

Yes, we gladly accept annually memberships with a cost savings benefit of 2 months free.

Rather than setting rigid requirements, our users are typically individuals who have taken a formal programming course or are self taught developers. That said, regardless of past experience, users need to be problem solvers with a hunger to learn and be innovative in their troubleshooting approach.

It is for those who are not good test takers and learn more by actually doing than in a classroom setting. Amateurs and professionals alike can level up with our hands on real world courses. Our course focuses on competency and retention as opposed to rote memorization and complex mathematical models. Upon completion of our course, users will walk away with the skills needed to work for employers with varying levels of complexity.

Your subscription will give you access to our Codespace. Monday through Friday you will receive a new exercise with a direct link to our repo. The subsequent exercise will contain a link to the PR containing a solution to the last exercise.

We offer 20 hours per month with 4 cores and 8 gigs of RAM for a seamless experience.

You will need fork out repo and create a separate Codespace under your GitHub account. To offer our users the best possible experience we do not support running our codebase natively on your local machine.

Substack is a digital newsletter subscription platform. We use it to send out our weekly exercises and process payments.

You can view our previous email lessons as posts over on our Substack page.

Everyone has a different aptitude level. Some are able to piece things together and hit the ground running with little background. Others need more context in order for things to make sense. Our recommendation is to have taken at least a basic programming course prior to subscribing.

Given the subjective nature of how difficult a problem is or is not, it is entirely up for interpretation. Worst case scenario you can wait for the next example to view the solution and reverse engineer why it works.

We utilize a project originally conceived by Google. It is a demonstration project for an e-commerce platform comprised of several microservices written in 7 languages.

Each lesson will be independent from the pervious lesson.

We send our own take on the solution in the intro for each subsequent lesson as a pull request. Think you have a better solution? Drop us a message explaining the solution and why and we will feature your solution at the start of our next exercise. Worst case scenario, just reply back to the email with your question.

We ask that you don't. We dedicate time each and everyday to come up with relevant problems that are highly relevant and concise in nature. That being said, we encourage our users to spread the word to increase our audience thereby improving our feedback.

You may be looking for a new job and want to keep your skills sharp. Or you are just starting out as a developer and want to learn the proper way to debug your application. Or you work with a smaller more junior team looking to level up their skill sets. Or you simply love coding and solving puzzles. If any of these are the case, this course is likely for you.

Suggestions are more than welcome, we will highly consider all feedback. One of the great things about Computer Science is that there are more than one way to solve a problem. We do not claim to be the end all. In fact, if you can provide a more optimal solution to any algorithm, you will earn yourself a shout out and kudos in our next email thread. Simply hit the reply button and cast us your take, we're all ears.

Debugging is more of an art than a science. Like a muscle, it grows over time with practice. While you cannot account for every scenario while coding, we give you tools and advice that should come in handy for troubleshooting your own applications. Unlike other courses, we go against the grain and do not follow happy path scenarios. We showcase real scenarios you are likely to encounter in a professional setting.

Simple, we use time to your advantage. By spending 30 minutes a day on our exercises, you can significantly enhance your skills over time. Landing your next job could take months. We see this as an opportunity to study without sacrificing nights and weekends. Crush your next interview by using our exercises to stay sharp.

Bootcamps teach devs how to write code under ideal conditions. We show how to troubleshoot and remove bugs. Like in the real world, you will not be starting from scratch and will need to interact with a pre-existing code base written by several engineers.

There is no question, Stack Overflow is a great resource for developers when things do not go as planned. Our goal isn’t to produce code for precise scenarios, it is to instill a level of problem solving amongst developers. We showcase to devs the tools available to debug their own applications.

Certifications focus on specific tech stacks and cost hundreds, if not thousands of dollars to achieve. Studying for certifications typically takes hours and usually requires rote memorization. Instead, we focus on understanding core computer science principles. Made famous by most tech companies, software developer interviews include a white boarding question. This is where the algorithms we send directly to your inbox come into play. We have not seen anyone ask a cert related question in the form of a white boarding exercise thus far.

Sad but true, most software developer interviews consist of edge cases. Basically, the hiring manager wants to assess your problem solving skills. In most cases, it's not the solution that matters to the hiring manager, rather its your approach to finding a solution. This is the same approach you will need to take for solving our exercises.

The microservices demo is a fully working e-commerce site comprised of several microservices written in a variety of languages including GO, Java, etc. It is an unofficial google project. Our source code is a fork off the original project where we have built additional features and functionality designed with an emphasis on debugging.

You could, however, it would require self discipline and due diligence to read and understand the algorithms. It is difficult to maintain a set schedule of time carved out of your busy day to dedicate to the book. Instead, let our community hold you accountable. Our answers are carefully crafted in such a way to help the reader make it stick. Sign up with us and you'll get a problem and solution sent to your inbox Monday through Friday.

You may find some similar problems on a blog post somewhere. What differentiates this Substack is our consistent postings overtime. Our exercises are carefully crafted by developers with professional experience.

Here is a great lesson from GitHub themselves which should give you all you need to get started. Check out there https://lab.github.com/githubtraining/introduction-to-github

Don't take our word for it. “With the pandemic, many software companies decided to go completely remote. If there were already good offers before, in 2021, there will be more opportunities for developers to work at home. The salary range for a Software developer goes from $30,000 a junior developer to more than $120,000 annually in the United States.” - Desiree Perala https://medium.com/the-post-grad-survival-guide/5-proven-ways-to-actually-make-money-online-in-2021-4f35749a6c7a Now more than ever with businesses moving from brick and mortar stores to e-commerce, there are more opportunities than ever for coding in the digital space. Whats better is now practically everyone is remote, so it is possible to earn Silicon Valley salaries from anywhere on the planet. It purely comes down to skill, this is what we help our users build.
