The usual issue I hear about is that it is "bloat", it includes tons of stuff that are not actually needed for the actual application itself, but you still get it because you include a full browser.

Qt has a dual commercial/GPL license, the commercial one is one of the most expensive licenses I've seen, so it's an instant no-go for most commercial software, especially for free as in beer desktop applications like VS Code. Also electron allows your boss to recycle javascript code meant for browser clients, so it's a no-brainer really.

worked for 1,5 years as an IT Consultant making over twice the median wage in my city, and i can honestly say i didn't create a single dollar of value during that time. My actual use was as an asset - my company could put me on a list and advertise me to potential clients as a highly trained python/SQL/Java/whatever expert (this was my first job out of college), and convince them to sign lucrative contracts. They wouls then put together a team to work on whatever they convinced the customer to pay for, where 70-80% od this team was outsourced - of course, these guys did most of the work.

In the last few months I've been laid off - assumed this would happen too, as the economic situation has big companies thinking a bit more rationally about this contracting work, I'm sure.

>Site reliability engineering (SRE) is a set of principles and practices that incorporates aspects of software engineering and applies them to infrastructure and operations problems. The main goals are to create scalable and highly reliable software systems. Site reliability engineering is closely related to DevOps, a set of practices that combine software development and IT operations, and SRE has also been described as a specific implementation of DevOps.

This is a thread for all discussion of Site reliability engineering

SRE is usually used at larger organizations which have multiple applications, services, etc. Where it gets confused with devops is that devops is automation and streamlining of traditional sysadmin tasks related to integration and deployment pipelines, essentially programmatically managing traditionally manual processes like testing and deployment to various environments. Whereas SRE is automating sysadmin tasks related to performance, observability, and reliability, as is in the name. The job devops engineer is replacing is the traditional sysadmin, wheras the job the SRE is replacing is whats known as a production support engineer or creation software engineer, less well known but essentially a SWE who's job it is to support applications. Its not support like helpdesk-install windows or whatever, its support engineering of an application, or set of applications, restarting scheduled jobs, database tasks, debugging java code, if heap utilization is too high or whatever. Essentially providing L2 support for complex enterprise or microservice type applications (L3 handled by the SWE's).

SRE is automating those tasks and building software that automatically monitors ops and programmatically restart services, etc. Essentially automating the job of a traditional production support engineer so that the system self heals and automatically detects and solves common issues by itself. Google invented SRE role so that it could create the outside appearance that the service is always up. The most extreme example is the chaos engineering/chaos monkey approach to SRE invented by netflix which had its reliability engineers invent tools that automatically crash certain servers in production so that they could make sure the system keeps running no matter what.

So both SRE's and DevOps engineers are focusing on automating traditional sysadmin tasks so they ovePost too long. Click here to view the full text.

I'm not a huge fan of go because the language is essentially the fixed gear hipster bicycle of programming language. The whole golang started as essentially another version of the Plan 9 version of C started in the early 1980s. Even the golang mascot is literally a copy of "glenda" the plan 9 mascot:
https://en.wikipedia.org/wiki/Plan_9_from_Bell_Labs
The designers of go essentially decided to eschew every advance in programming language theory from after the 1970s and just recreate another version of C: an imperative, structured language with no FP/OOP features, generics, etc. with a focus on distributed systems. Go also has some significant drawbacks, like the fact that concurrency is pretty difficult and error prone, just as it would be in C. That's fine for some use cases but the idea that this could be a generally applicable programming language is nuts. Golang could probably be used in a lot of places where C, C++, Rust, etc. could be used.

But the idea of writing general purpose back end enterprise/web software in it is pretty unappealing to me. I sincerely hope it doesn't catch on in these spaces.

The only portable threading library until c++11 was boost::thread, though they probably had a posix environment where pthreads were available to avoid such a beast. I wonder how both compare to the common-lisp quasi-standard bordeaux-threads.
>>18024
They would avoid any language with only a single implementation and no formal language specification whatsoever.
JPL follows a subset of the C++ MISRA coding standards. You can't write such a thing for rust, because it doesn't have the guarantees that let you know what unspecified behaviour to avoid or account for.
The limited hardware support and heavyweight toolchain (compared to C or Lisp) may also factor into the lack of adoption.

TLDR + Modifications:
1. Watch multi mile circles with NVG and RGB cameras.
2. Watch at a resolution that you can see individual people and cars move.
3. Object Recognition to observe cars and humans.

Major concern:
We as the American Left expect CCTV and Phone cameras, not watch every single human and car within a 10 mile circle at the same time.
Our activism is not prepared at all.
