I’m sorry but your design is not comprehendible by me, and I’ve done lots of
TCP based services.
i think you only need to emulate classic TCP processing - a reader thread (Go
routine) on each side of the connection using range to read until closed. The
connection is represented by 2 channels

@Egon,
I'm sure many here would jump in and assist, but you need to help us to
help you by spelling out, specifically and exactly, the problem(s) you want
solved. A few sentences on each challenge should suffice.

Agreed, I see goroutines in general as a big win. But what I intend to talk
about in the presentation:
- we have two unidirectional flows of data resembling something like a TCP
socket, easy to do with two goroutines with a for loop
- let's add caching, so some requests do not go to the server
-
Oh, yeah, that's perfect.
However, anyone get it working?
I think I'm following the instruction correctly, however, whatever I tried,
I always get no data to show error. I use benchgraph from latest git.
Anyone able to get benchgraph from latest git working?
Thx.

To clarify, with Go’s very lightweight threads it is “doing the multiplexing
for you” - often only a single CPU is consumed if the producer and consumer
work cannot be parallelized, otherwise you get this concurrency “for free”.
You are trying to manually perform the multiplexing - you need

Can you just run multiple instances of your program, each independently
fetching messages from SQS?

Hello,
I would like to export the runtime run queue length (as can be seen using
"go tool trace") to our monitoring infrastructure but I am unable to find a
way to access it using the runtime package without traces enabled. Is the
run queue length accessible from application code?

A channel is much closer to a pipe. There are producers and consumers and these
are typically different threads of execution unless you have an event based
(async) system - that is not Go.

So it was an XY problem?
No floating point operations are necessary to do that. Also, check

I can't change expectations. It is to convert a byte count into a human

I found out that I can produce the expected result by using math.Round. See

For my use case, I ended up converting "manually" the

Agree with Ian.
Solutions are: change expectations, use decimal floating point, or use a
base-independent decimal representation. The latter implies scaled integers.
Quick, ugly, and typed on one hand from bed, but here it is:

999000/1000 = 999.0
There are goroutines in the examples of course, just a single goroutine per
bidi channel seems hard. By contrast, I've worked with actor systems before
and they are perfectly fine with a single fiber.

Channels are designed to be used with multiple go routines - if you’re not you

I'm preparing a short talk about Go channels and select. More specifically,
I want to show what not to do. I chose a bidirectional communication
channel implementation, because it seems to be a common base for a lot of
problems but hard to implement correctly without using any extra

I have noticed that printf performs an apparently inconsistent rounding of
floating point values.
I divide a big number by 1000 and printf the resulting value with "%.1f".
Here is the code: https://play.golang.org/p/e7dD3c6IHq2
I would expect the rounding rule to be "round away from zero" as
Hi Ian,
The Go code fetches a message from SQS and calls the C code to parse the
log messages.So this is what the cgo service does.
I would like to run the same service on different processes independently.
I am not sure how to achieve this in Go. Can you please guide me here.
Thanks,
Nitish
