    To prevent SQL Injection attacks to sanitize input data. You can either validate every single input or validate using parameter binding. Parameter binding is mostly used by developers as it offers efficiency and security. If you are using a popular ORM such as sequelize, hibernate, etc then they already provide the functions to validate and sanitize your data. If you are using database modules other than ORM such as mysql for Node or Mongoose, you can use the escaping methods provided by the module. Let's learn by example. The codebase shown below is using mysql module for Node.

    It gets more perverse if you need to flatMap, or transmute components of map types, etc. If you want even more power, take a look at This sort of container manipulation bread and butter for business processing. I use it every day, sometimes with a dozen operations. This (with liberal use of `final` values) makes for some pretty functional-looking code.

    I'll grant you the Kotlin or Scala version is slightly more compact. But not fundamentally different, like the Go version.

    I (and the pretty much every language designer in the post-Java era) disagree with you about checked exceptions, but that's a whole different thread...

    Project mention: Interview for JetBrains: Why Localazy developers ️ Kotlin? | | 2022-07-16

    For data, we use S3/MinIO, sharded PostgreSQL, and Elasticsearch. For accessing the database, we don't use Java Persistence API (JPA) but as it is easier to tweak queries manually, and we use a lot of specific queries and offload some processing to the database. Many of them are written to use PostgreSQL's specific features, e.g., JSONB columns, so we don't consider database independence a critical factor.

  • kid-bank

    Now known as Kid Money Manager. It's not a real bank, but keeps track of your kid's earnings, savings, and spending. Watch me Live Code its development on Twitch.

    Project mention: Ask HN: Have you created programs for only your personal use? | | 2022-04-13

    I created "Kid Money Manager", a tool to help manage my son's virtual account. He wasn't old enough to open his own bank account when I started, but we needed some way to track his "earnings" (returning bottles for their deposits or gifts from grandparents) and spending. It has both a Web UI and access via SMS text messages. We mainly use the text messaging—entering transactions at the store, etc.— since I didn't want to write a dedicated phone app for such a simple interaction.

    Created it from scratch, live coding it on my (JitterTed.Stream) Twitch channel (and some videos on my YouTube channel at JitterTed.TV). Written using TDD in Java + Spring Boot, deployed on Heroku and open-source at

    I also recently wrote "Format Hero" (, because I could never remember which letters to use in Java's DateTimeFormatter. Was also a good demonstration of Hexagonal Architecture and, of course, I live coded it, TDDing all the way. Source is at Still some work to do on that one, but filled my immediate need.

    Project mention: 🔒 How I protected my Minecraft cheating client | | 2022-01-30

    I've made a basic repository public about how to get such an HWID easily. Of course the method I've implemented into my client was slightly different from the public repository, but it's still pretty simple. This was another simple way to make sure the right person was logging to the right user and sharing accounts.
