How to Catching Runtime Errors in Compile Time with Typescript

Catching runtime errors in compile time with - Typescript?

Hi, I’m Domagoj Cerjan. I work for Oradian, a SaaS company that enables financial institutions in some of the poorest and remote regions of the world to reap the benefits of moving their operations to the cloud. I’m part of the frontend team and vigilantly bore my colleagues with FP and dabble with all things Typescript, React and Redux. In my free time, I develop 3d rendering engines for fun and since that is the domain I know well, I often try out different languages and approaches to solve the same problem over and over again.

Catching Runtime Errors in Compile Time with Typescript

Hi, I’m Domagoj Cerjan. I work for Oradian, a SaaS company that enables financial institutions in some of the poorest and remote regions of the world to reap the benefits of moving their operations to the cloud. I’m part of the frontend team and vigilantly bore my colleagues with FP and dabble with all things Typescript, React and Redux. In my free time, I develop 3d rendering engines for fun and since that is the domain I know well, I often try out different languages and approaches to solve the same problem over and over again.

Intro

Today, nVidia’s high-end GPUs can do real-time raytracing, open-source AMD GPU drivers rock and cross-platform gaming is more of a reality than a dream. A few things remain as they were decades ago - 3d graphics is the domain where languages such as C/C++ have been and still are used almost exclusively for writing game engines, GPU interfacing APIs are still plenty - from old and tried varieties of OpenGL and DirectX 9 - 11, to all modern and extremely low-level Vulkan, DirectX 12 and Apple’s Metal.

While C and C++ do provide us with the ability to write really fast programs, they lack in a lot of other areas, from memory safety, debuggability and ease of use to portability and flaky type systems - even though one can do wonders with C++ templates which are in themselves a pure FP language with a weird syntax, they are not languages someone can pick up in a week or two.

Having cross-platform in mind, one could argue that there is but one platform which is available to everyone, from any flavour of Linux, Unix or Windows be it on mobile phones, tablets or personal computers or even washing machines and Roomba’s (because IoT). That platform is of course - the Web. Developing 3d accelerated games for web is nothing new, WebGL has been with us for some time, WebGL 2.0 is already supported in newest Firefox, Chrome and Opera and there exist already well battle-tested engines such as Three.js, or one could even use emscripten to port any of the C/C++ engines to web more or less.

But what if we want to write an engine using something more modern, specifically targeting the web browser as the environment and trying to make it as robust as possible? Well, I chose Typescript because of its pretty powerful type system, awesome tooling and amazing integration with IDEs (emacs via tide, VSCode by itself, …) and WebGL 2.0 because this engine is my toy and will probably never see the light of day so there are no issues with only supporting a few web browser. I intentionally chose not to use Idris here, even though it compiles down to Javascript, because i wanted to see how far i can push Typescript’s type system.

The problem

After the lengthy intro, a little heads up - WebGL 2.0 API is still a low-level-ish API dealing with a bunch of byte buffers, very specific rules what values can go to which arguments of functions and when can they even be invoked and in which order. It’s a mess for anyone who is used to write and/or look at pure functional code. In its essence 3d APIs are as far away as you can possibly get from purely functional. You are dealing with the outside world after all ;)

Speaking of said rules - they often come from tables defined in WebGL specification that define which combinations of arguments are valid for a certain API function. This post will deal with how to make one of the most commonly used functions - a function which uploads an image to the texture - gl.texImage2D safe from runtime errors caused by not obeying those rules.

Need troubleshooting assistance to get rid of QuickBooks error 3371 status code 11118? If yes, feel free to reach our QuickBooks experts at (844-888-4666) and get the error resolved immediately.

What causes QuickBooks error 3371 could not initialize license properties?

Apart from the unregistered Microsoft MSXML component, there are several other reasons that can trigger QuickBooks error 3371 could not initialize license properties, such as:

  • The QB.registration.dat file, which contains all the license information, is damaged or corrupted.
  • Due to outdated Windows operating system.
  • Any QuickBooks program file is damaged or corrupted.

What should you do to rectify QuickBooks error 3371 status code 11118?

Solution 1) Manually register Microsoft MSXML DLL files

For the 32-Bit Windows operating system:

  • Open the Run command window by pressing Windows + R keys on the keyboard.
  • Type “cmd” in the Run command dialog box and then press the Enter key to open Command Prompt.
  • Now, you need to type regsvr32 MSXML6.dll in the command prompt window and then press the Enter key.

For the 64-Bit Windows operating system:

  • At first, press Windows + R keys simultaneously to open the Run command window.
  • In the Open: field, you need to type “cmd” and then click on the OK button.
  • At the C: prompt, type cd\windows\syswow64.
  • Thereafter, you need to enter regsvr32 MSXML6.dll and then press the Enter key.

Solution 2) Remove the Entitlement file and re-register QuickBooks Desktop

  • Open the Windows File Explorer by pressing Windows + E keys simultaneously on the keyboard.
  • Navigate to the following path: C:\ProgramData\Intuit\Entitlement Client\v8.
  • In the v8 folder, search for the file named EntitlementDataStore.ecml, and right-click it.
  • Choose the Delete option and then hit the Yes button to confirm.
  • Open the QuickBooks application and re-register it using the license & product information.

Solution 3) Get the Windows updated to the latest release

  • Select the Windows Start menu, type “settings” in the search column, and then open Settings.

Beginner's Guide to Compilation in Java

Java applications are complied to bytecode then JIT and JVM takes care of code execution. Here you will find some insights about how JIT compiler works.

I am guessing that many of you use Java as your primary language in your day-to-day work. Have you ever thought about why HotSpot is even called HotSpot or what the Tiered Compilation is and how it relates to Java? I will answer these questions and a few others through the course of this article. I will begin this by explaining a few things about compilation itself and the theory behind it.

Turning Source Code to Machine Code

In general, we can differentiate two basic ways of translating human readable code to instructions that can be understood by our computers:

Static (native, AOT) Compilation

  • After code is written, a compiler will take it and produce a binary executable file. This file will contain set of machine code instructions targeted for particular CPU architecture. Of course the same binary should be able to run on CPUs with similar set of instructions but in more complex cases your binary may fail to run and may require recompiling to meet server requirements. We lose the ability to run on multiple platforms for the benefit of faster execution on a dedicated platform.

Interpretation

  • Already existing source code will be run and turned into binary code line by line by the interpreter while the exact line is being executed. Thanks to this feature, the application may run on every CPU that has the correct interpreter. On the other hand, it will make the execution slower than in the case of statically compiled languages. We benefit from the ability to run on multiple platforms but lose on execution time.

As you can see both types have their advantages and disadvantages and are dedicated to specific use cases and will probably fail if not used in the correct case. You may ask – if there are only two ways does it mean that Java is an interpreted or a statically compiled language?
