But in my humble opinion, those projects shouldn’t really exist.
What's the point of your opinion if not only do these projects exist but they are also pervasive?
You cannot wish things away and pretend reality is something different.
The biggest news to me is that GitHub allows users to search code. Every single time I tried to search something in GitHub, search results were next to completely useless, and always a sure-fire waste of time and effort.
There's hope, I guess.
but I don’t understand why they don’t self-host
Why would anyone self-host a FLOSS project? Trade secrets is not a concern, nor is it barring access to the source code repository. Why would anyone waste their resources managing a service that adds no value beyond a third-party service like GitHub?
Why do so many programs use rational databases instead of loading the data during startup and keeping it in memory?
I presume you're referring to relational databases instead of rational.
The responsibility of a RDBMS is to implement a set of performance-focused data structures that help clients reliably get the data that they need in the fastest possible way, without having to reinvent the wheel.
More often than not, this data does not fit in the heap.
Also, in many usecases there is more than a single client.
Hope this helps.
I think my interview/offer ratio is somewhere below 1%.
Keep your spirits up, and be mindful that there are tons of job adverts out there that don't actually have a real job position to fill, and are only used by recruiters and consulting companies to harvest CVs and meet their internal quotas. 1% sounds about right
your 2 decades of experience mean much more than memorizing algorithms, you know how to produce real value
That's all fine and dandy but the HR recruiter that can't tell apart git from grunt needs to cross boxes in the skills assessment section, and if you don't ace coding challenges you are as good as dead to them.
Elon Musk buying it.
Holy hell, you went for the jugular.
Python is only good for short programs
Was Python designed with enterprise applications in mind?
It sounds like some developers have a Python hammer and they can only envision using that hammer to drive any kind of nail, no matter how poorly.
HTML is bad. The language itself feels unintuitive and is clunky compared to modern markdown languages, and let’s be honest, your webpage just consists of nested tags.
My websites do not consist of nested divs. Your webpages might just consist of nested divs, but only if you are clueless about what you're doing and are oblivious to basic stuff like accessibility support.
CSS is bad. Who knew styling can be so unintuitive and unmanageable? Maybe it made sense 25 years ago, but now it’s just terrible. It’s very clunkily integrated with HTML too in my opinion.
Being unmanageable is the output of the developer team, not the languages they use. Decoupling Presentation from the data and semantics never ceases to make sense. CSS has many issues but the way its integrated with HTML is certainly not one of them.
Frankly, you sound like you blame your tools a lot.
Java gets a bad reputation from proponents of FOMO/fad-driven development, but the whole Java ecosystem was built for the web. Anyone is hard-pressed to find a better tech stack than Java-based frameworks without resorting to hand waving and passing personal opinions as facts.
I love C# and the whole .NET Core ecosystem, but even I have to admit it's very hard to argue against java.
Also, double can and does in fact represent integers exactly.
I've been working with Agile for years and I worked with people who burned out, but there was not even a single case where Agile contributed to burning out, directly or indirectly. In fact, Agile contributed to unload pressure off developers and prevent people from overworking and burning out.
The main factors in burning out we're always time ranges from the enforcement of unrealistic schedules and poor managerial/team culture. It's not Agile's fault that your manager wants a feature out in half the time while looming dismissals over your head.
It's not Agile's fault that stack ranking developers results in hostile team environments where team members don't help out people and even go as far as putting roadblocks elsewhere so that they aren't the ones in the critical path. Agile explicitly provides the tools to make each one of these burnout-inducing scenarios as non-issues.
