Riemann VS GNU Emacs

This is fine- we do something similar using riemann.

"It can't go into infinite loop" is utterly irrelevant. Over last maybe 15 years I've used a bunch of apps that just used their own programming language (from simple DSL to "just write exactly how the app is supposed to handle data") and literally not a single time has that become a problem.

Metrics are measurements of something about your system. They are numeric values, over an interval of time, usually with associated metadata (e.g., timestamp, name). They can be raw, calculated, or aggregated over a period of time. They can come from a variety of sources like servers or APIs. Metrics are structured by default and can be stored in open source systems like Prometheus and Riemann or in off-the-shelf solutions like Amazon CloudWatch and Azure Monitor. These optimized storage systems allow you to perform queries, create alerts, and store them for long periods of time.

Reason #1 - Riemann https://riemann.io/

Riemann is a tool for distributed system monitoring. It aggregates events from user servers and applications, combines them into a stream and transmits them for further processing or storage. Greater flexibility and fault-tolerance make Riemann different from other similar systems. Moreover, it’s written in Clojure almost completely. The code is available on GitHub and is distributed under Eclipse Public License 1.0.

I did a new release today of Mirabelle, a stream procesing tool heavily inspired by Riemann. I also spent a lot of time on the documentation website if you want to try it, and also wrote an article today about an use case.

Consider dabbling in a project to get your feet wet first. You have a neat problem you want solved? Give it a shot. There an interesting open source project, fork it and tinker with the code. This will be tremendously educational both vocationally and will help you get a feel for if you'd like to work in clojure all the time. There are a lot of projects, but I chose https://github.com/riemann/riemann to read and try better to understand real world clojure.

gnu.org - contains everything you need to research his philosophy.

stallman.org - personal website, contains a lot of opinion, but I absolutely respect this man in all what he says.

emacs.org (redirects to https://www.gnu.org/software/emacs/) - his non-philosophical work, one of two mainstream console text editors.

Forever, there was a file included in stock Emacs, `spook.el`, which could be hooked up to automatically add random strings of "interesting" keywords to each of your email or Usenet messages (in signatures, or in headers like `X-Spook`).

Looks like copyright date of 1988:

Try `M-x spook RET` in an Emacs buffer.

If you want to spare a couple of detours, you probably could start with Emacs Org-mode according to Greenspun's eleventh rule: "Any sufficiently complicated PIM or note-taking program contains an ad hoc, informally specified, bug-ridden, slow implementation of half of Org mode."

Emacs: winget install GNU.Emacs

The whole cl-lib thing is a total disaster:

https://github.com/emacs-mirror/emacs/blob/master/lisp/emacs...

They added cl- as a prefix to each Common Lisp symbol.

FIRST is now called cl-first, CAAAR is now cl-caaar .

I would really prefer if GNU Emacs removes all Common Lisp functionality, instead of creating this really wacky stuff, with discussions about this topic every year.

Never too late to try! Take your time. Emacs will outlive us all. https://www.gnu.org/software/emacs/

GNU Emacs is a versatile, open-source text editor that offers extensibility and customization—a sort of self-documenting real-time display editor. Our thanks for the suggestion go to CartanAnnullator.

Emacs

Their DEFUN and DEFVAR macros for example let us define a function or a variable that will be available as a Lisp function, and can be used as an ordinary C function from the C code. Emacs is written in pure C99 language and works with both GCC and Clang I believe. We can just define a C function via macro, and it is auto exported and made available to Lisp. For example my first patch to Emacs was for this function (we added "count" argument to make it possible to skip enumerating files in a directory for the case when user code is just interesting if a directory is empty or not):
