    Instead, find projects involving some sort of system you can build yourself, or one that involves interacting with high-performance kernel API functions. Obvious examples include things like socket programming, audio programming, graphics programming, etc. Take a look at for inspiration. Build something up to the point of functionality and then try taxing your implementation and start learning about the performance characteristics of your application.

    Project mention: Slack is the opposite of organizational memory | | 2023-01-26

    Compared to existing and free software chat solutions[1], Slack however looks like such a kindergarten tool. It has a terrible performance. Every time one switches a channel, it basically burns a CPU. The loading of messages when scrolling down a channel with many message is not working well, not pre-loading enough messages to make scrolling a smooth experience. Instead one has to wait half a second or so until the next 20 messages or so are loaded, then scroll, then wait again, then scroll ...

    And the "markdown" text input oh my. Rarely have I seen a worse markdown input than in Slack. Maybe on Bitbucket or Confluence it is worse. It is as if they have decided to not use any existing and perfectly well working markdown parsers, but instead get an incapable team of engineers to reimplement a bug-ridden one with missing features. One cannot even insert an image at any play in the method, but only at the bottom. That means one needs to refer to the image in the message, when otherwise one could have simply had the picture in that place where it is relevant. It is such a headache for anyone more familiar with markdown. At this point just give me a plain text input, that has any normal off the mill markdown parser to properly translate my text into a message.

    Oh and they still have not managed to implement voice chat according to standards properly, so that it works in all modern browsers. While other more feature full chat programs like Discord had this solved for years ago, Slack is still the same old shit. Now I have to start ungoogled-chromium every time I want to enter a "Huddle" and navigate to their website, where they will bug me with their incessant popup asking me to use their desktop app, which I have to decline every. single. time. because chromium does not remember to block such popups from websites.

    So basically Slack is quite crap.

    Project mention: Deploy a static website on AWS with terraform | | 2022-08-25

    In the previous article, we deployed an API as a docker container on AWS EC2. In the current article, we are going to deploy a simple website on AWS without the backend (so next we can add it 😉). We will distribute the content using AWS S3 and AWS CloudFront (content delivery network service). As a frontend will be used an open-source Start Bootstrap example with an MIT license. Everything we deploy in the article is supported by AWS free tier. All the code related to the article can be found in GitHub repo.

    Project mention: My new toy just arrived! | | 2023-02-02

    The install for it is an absolute nightmare for me. I want to use SSL, because I expose my servers to the WAN, but I'm such a n00b when it comes to that stuff that AMP was able to set it all up with the click of a button. Literal auto-install. AMP also allows for containerization. I do say however that I will likely give a second shot now that I have more experience with the network side of things. I like that it's open source and seems to have the vast majority of EGGS already.

You will install the same dependencies and the platform following the same instructions you followed originally. Notice that there are specific instructions and commands to install Node.JS and Git under the title Linux (e.g. Ubuntu, or Raspberry Pi running Raspberry Pi OS/Raspbian) Pre-Requisites. You may, of course, reuse the Github fork and token you created during the first installation.

    Project mention: Behind the Scenes of Go Scheduler | | 2022-03-19

    OK, no more surprises. I promised with that, we now have a full understanding of the main ideas, both big and sneaky, behind the Go scheduler. We started out with a list of goals. How did we do with our goals? Use a small number of kernel threads. We can support high concurrency and we can leverage parallelism. We scale to N-cores and this falls out of those three ideas that we discussed. Let's move on to the harder questions. What are the limitations of the scheduler? Well, for one, there is no notion of goroutine's priority. It uses a first in, first out runQueue vs Linux scheduler which uses a priority queue. Now the cost-benefit tradeoff is doing this might not actually make sense for go programs. The second limitation is there's no strong preemption, so there is no strong fairness in latency guarantees. It's entirely possible for a goroutine in certain cases to bring the inspire system to slow down in a fault. And finally, the third limitation that I want to touch upon today is the scheduler is not aware of the actual hardware topology, so there's no real guaranteed locality between the data and the Goroutine computation, and with that we have come to an end and thank you for reading.
