feedmegin posted:Technically I can think of ways of doing that, e.g. System V shared memory segments i worked on some data compiler that was split up across 20-30 binaries that used sysv shared mem to pass data between stages. doing non-stop pointer arithmetic from a few constant addresses instead of just writing out a file made it impossible to port because the entire program depended on everything being at 0x???????? instead and plus now you dont even have to free() anything!

Below post in short: I've been thinking about how to design and document complex Go processing pipelines. My question comes down to, do people already do this, how do they do it better, and what tools do they use? The direction that I have had success with is doing it visually. I have complex data pipelines I'm trying to design for data processing of a project. Any time I go down the rabbithole of using mutex/semaphores to solve a nontrivial sub-task I quickly get to the point where I cannot reason any longer with the logic, it feels as though the implementation has far outgrown the complexity of the problem and the chance of new eyes coming into the project and realistically understanding the logic is low. So, I'm using Go. Go's design is influenced by CSP and as such, I've had success with decomposing each task into a series of broad state machines (as defined by their communication channels), and linking these state machines up in a graph with the directional edges being the data structures I use to communicate. Some state machines that share the same task work in a pool (eg performing independent data compression), and there will be 1->n relationships between senders and receivers. This graphical decomposition has helped me immensely, I use something primitive like LibreOffice Draw to draw tasks in the processing pipeline without worrying about the data structure specifics and without having written down a single line of code, this captures not only the flow of information but whether the communication channels are 1-N, N-M or N-1. Sometimes it makes sense to have 1-N state machines but have separate communication channels for each of them (this delivers some cool guarantees in processing order but I'm not going to go into specifics, that's not the point I wish to discuss). From there I work on the data structures for the initial state machine set of outputs and as I do that, and focus on implementation, it becomes apparent that many of these state machines were overdesigned and their functions can chained together in the same goroutine. What I ultimately would like to see is a page or two of A4 describing the flow of an entire program to serve as the most efficient way for a new developer to know the intent of a program. Each state machines would have 1) the filename, 2) the function of the toplevel goroutine that is responsible, 3) short description (<10 words), and the edges between these state machines list the datatype being sent (and enough of the struct contents for intent to be known), and conceivably a decent way to show fanin-fanout relationships Perhaps I can do the above using GraphViz, describe it all in a relatively simple .dot file, but getting it to generate a graph that looks "right" is another matter. Does anything exist that would make this easy?

I tallied the positives and negatives and (for me) it still seems a net positive. I've done up a small descriptive format and turn it into a dot file file with Perl. Later on I'll augment it to extract out the data structures from the Go code and display them in the edges in a verbose mode. The hierarchical format is good enough that i can embed it in a comment or whatever and has enough knobs and whistles in it that I can affect hint to graphviz where to place nodes.

people tend to forget about poo poo like that. javascript was everywhere back in the day. netscape put it on servers, in proxy config files, and for a brief time, as email filters in netscape mail. this sort of dumb "javascript server" approach has been done quite a lot. mozilla rhino & the java "scripting" api for servers were used quite a lot. macromedia released a beta for "flex server" in 2003 which allowed you to write actionscript (a javascript variant) on both the client and the server. it was hurrah'd at the time because you could share code. the word "isomorphic" wasn't invented yet. it was then rediscovered in 2006 with "aptana jaxer" which pulled off a similar trick, letting you build one html and "embed" server-side components in it (similar to coldfusion) finally, in 2008, we saw the release of "v8cgi" which became "teajs", which was a bog-standard cgi server built on top of v8 & javascript. and then in 2009 with "nodejs", which used a lot of the original v8cgi code.

Having said that, my company has a legacy team on azure which they're migrating away from (and also migrating away from c# at the same time for... Reasons?) but they keep bitching about having to learn scala which the rest of our stack is in so they're going to switch to/learn go instead so I guess I might get some first hand experience when I need to interact with their poo poo

I interviewed with a company whose backend was written entirely in go for unclear reasons. It was the backend of Vivino, a wine app, and I'm having a hard time telling why it would need such speeds where they could probably develop in python and get more done faster.

Near as I can tell, they realized that generics were absolutely needed for maps, but instead of implementing generics they just hard-coded maps into the loving language. When I last checked (admittedly quite a while now), maps didn't allow specifying non-default key comparison, so something like C#'s Dictionary<string, int>(StringComparer.OrdinalIgnoreCase) would not be possible. Nor would it be possible for anyone else to implement properly, seeing as the data type is built into the loving language.
