Flutter summer project

As a summer project, I helped out a team at my local university in a project combining open data with students seeking an apartment to rent, especially when moving to a new city. They designed a mobile app for this task, and I was to implement it.

I decided to try out Flutter this time instead of react-native.

Again, there are several blog posts and even official documentation on how to transform from native or react-native development into using Flutter. Here are my two cents though

Dart. Google's solution for building UI:s. The syntax is familiar looking. I like the way how it is not limited to any particular form of programming, but the guideline for Flutter enforces a specific declarative style. One of the best parts of Flutter development is the named arguments.

Development environment. One of the better setup experiences. A self-contained diagnostic tool which alerts if something is not set correctly. Updating is a simple git pull and some installation scripts. I had no trouble in running the application in either IOS and Android simulators.

Flutter library. Out of the box, Flutter contains all the necessary UI elements (with Material design) for your simple Todo app. The elements or widgets in Flutter terms are split into stateless and stateful. The stateful ones have a well thought, although a bit verbose, manner of separating the state from the UI logic in a declarative way.

Testing. I only wrote plain old unit tests for the business logic and some UI tests using the flutter_test framework. I would say it is on par with react-native testing. I have yet to see a unit test framework for UI components which would work intuitively, and while Flutter certainly worked ok, I had some problems with gestures.

If I had to choose between Flutter and react-native, I would undoubtedly choose the former, especially if new to mobile development. Main reasons are, in my opinion better, typed, UI widgets, better development environment (including an excellent vscode plugin) and an overall faster and snappier app as a result.

RocksDB data recovery

I recently needed to do some maintenance on a RocksDB key-value store. The task was simple enough, just delete some keys as the db served as a cache and did not contain any permanent data. I used the RocksDB cli administration tool ldb to erase the keys. After running a key scan with it, I got this error Failed: Corruption: Snappy not supported or corrupted Snappy compressed block contents So a damaged database. Fortunately, there's a tool to fix it, and after running it, I had access to the db via the admin tool. All the data was lost though. Adding and removing keys worked fine but all the old keys were gone. It turned out that the corrupted data was all the data there was. The recovery tool made a backup folder, and I recovered the data by taking the files from the backup folder and manually changing the CURRENT file to point to the old MANIFEST file which is apparently how RocksDB knows which sst (table) files to use. I could not access the data with the admin tool, ...

I'm not a passionate developer

A family friend of mine is an airlane pilot. A dream job for most, right? As a child, I certainly thought so. Now that I can have grown-up talks with him, I have discovered a more accurate description of his profession. He says that the truth about the job is that it is boring. To me, that is not that surprising. Airplanes are cool and all, but when you are in the middle of the Atlantic sitting next to the colleague you have been talking to past five years, how stimulating can that be? When he says the job is boring, it is not a bad kind of boring. It is a very specific boring. The "boring" you would want as a passenger. Uneventful. Yet, he loves his job. According to him, an experienced pilot is most pleased when each and every tiny thing in the flight plan - goes according to plan. Passengers in the cabin of an expert pilot sit in the comfort of not even noticing who is flying. As someone employed in a field where being boring is not exactly in high demand, this sounds pro...

Careful with externalTrafficPolicy

On a project I am working on is hosted in an EKS cluster with the NGINX ingress controller (the one maintained by Kubernetes). It is deployed using it's official official Helm chart, which I realized, after a lengthy debugging session, was a mistake. The initial setup I aimed to improve had several flaws. Firstly, we were using the AWS Classic Load Balancer in front of the nginx ingress in the cluster, which has been deprecated for some time (years?). Continuing to use it makes little sense to us. The second issue was that we were only running one(!) nginx pod, which is quite sketchy since the exposed web services had essentially no high availability. I switched to the Network Load Balancer (NLB), which was straightforward - I just needed to change the ingress-nginx service annotation to specify the load balancer type as NLB: service.beta.kubernetes.io/aws-load-balancer-type: nlb However, increasing the replica count turned out to be tricky. When I bumped it up to two, I began to ...
