ZeroMQ VS aseprite

Slightly OT:

Are ZeroMQ and NanoMQ still widely used (and recommended)?

https://github.com/nanomq/nanomq

Remarkable, up until recently, requests for a new release were sumewhat brusquely rejected and marked as spam.

I wonder what made the maintainer change his mind.

FP Libraries: gRPC, ZeroMQ, and AREG are examples of libraries with a special focus on providing possibilities for Interprocess Communication. Developed using C++, they facilitate communication through predefined APIs, emphasizing functional programming concepts.

Unlikely, but they seem to be different things altogether. BlazingMQ appears to be a traditional message queue (think ActiveMQ), with message peristence. ZeroMQ is more of a network middleware (think Tibco Rendezvous), and does not include persistence.

BlazingMQ also appears to be more of a "platform" or "service" that an app can use (sort of like Oracle, say) -- ZeroMQ includes libraries that one can use to build an app, service or platform, but none is provided "out of the box".

Which makes it harder to get started with ZeroMQ, since by definition every ZeroMQ app is essentially built "from scratch".

If you're interested in ZeroMQ, you may want to check out OZ (https://github.com/nyfix/OZ), which is a Rendezvous-like platform that uses the OpenMAMA API (https://github.com/finos/OpenMAMA) and ZeroMQ (https://github.com/zeromq/libzmq) transport to provide a full-featured network middleware implementation. OZ has been used in our shop since 2020 handling approx 50MM high-value messages per day on our global FIX network.

I think the situation is more subtle than the poster admits.

No, ZeroMQ and successors do not tell you about socket state. You can't detect disconnection or reconnection. But then if a TCP connection fails in some way that does not lead to disconnection (packets getting dropped, remote machine powers down), it can't possibly tell you about that either, but you still need to deal with it. So in any case, you need some sort of application-level error detection and recovery; you need heartbeats, and serial numbers in messages, and a protocol for explicitly restarting a connection and performing the initial handshake. And once you have that, explicit connection events from ZeroMQ are much less important.

Admittedly, given that this is a TCP transport, reporting reconnections would still be useful, because TCP won't ever drop messages from the interior of a sequence itself (if it delivers 15, it has delivered 1 - 14 already), so you shouldn't need the serial numbers.

And if it's really not possible to detect authentication failures, than that seems rubbish. And it seems that is indeed the case: https://github.com/zeromq/libzmq/issues/3505

Aseprite is free if you compile it yourself [0], and can still be used for commercial purposes if compiled this way [1]. But I recommend buying it anyway to support the project.

Nitpick: Aseprite is source-available, not open source by the Open Source Initiative's definition. From the Aseprite EULA [1]:

> (g) Source code.

> You may only compile and modify the source code of the SOFTWARE PRODUCT for your own personal purpose or to propose a contribution to the SOFTWARE PRODUCT.

The OSI's definition of open source [2] requires distribution of unmodified and modified copies (with the exception of lone, unmodified copies; I read somewhere that writing a hello world program is a workaround):

> 1. Free Redistribution

> The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.

...

> 3. Derived Works

> The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.

"free software" is ambiguous to English speakers/writers, but "open source" is ambiguous in its own way.

That's not because you didn't know about it that it is a "new trend"

It's nothing new, and also exist in the tooling side of things

https://store.steampowered.com/app/431730/Aseprite/ - https://github.com/aseprite/aseprite

This is specifically targeted for Aseperite users, and also makes use of a great tool called TexturePacker by CodeAndWeb. Andreas from CodeAndWeb always helps me out when I email them, and the software itself is awesome, so I figured I'd give it a boost.

Are you on macOS? There is a known issue that we've just fixed and released a new version with the fix today as v1.3-rc7 (we're going to publish some release notes in the following days).

I'd never used Aseprite before, but it was luckily pretty straightforward to copy and paste and slightly edit the knight into a little spritesheet!

I modeled this simple computer in Blender and used the Pribambase plugin to create an animated texture for it with aseprite. I keyframed the animation in Blender and it works perfectly there.

One of my favorite "MS Paint" clones is KolourPaint[1]. I've been using it for over a decade (you have to search around to get it on non-linux platforms but I presently have it on MacOS). One of my favorite features is how it handles transparency, where it's just treated like another "color".

If anyone is heavy into pixel art, you may also be interested in Aseprite[2].
