Yes, it’s amazing how time has flown. I was there for the launch and surely it was just a few months ago.

It is part of LF and is a graduate now after being contributed in 2021.

I don't get what "Add" does

Ah, cool, thanks for the clarification. Good luck with it all, and congrats on the launch!

>What nothing we've found out there do (except perhaps kedro) is model the "micro" -- E.G. the specific fine-grained dependencies so you can take a look at your code and figure out how exactly it works.

Just wondering then @elijahbenizzy - how does Hamilton differ from Kedro?

>Pretty cool when you're added to a new project, have no idea what people have been working on for the past 2 months there and want to see where most of the actual effort was focused.

That's a neat idea!

That's a good point, but I guess for non-tech people activity => work and no activity => no work, so at that level it illustrates reasonably well, no?

Apple Music in a car when you are in an area with no network signal. Urgh! Try getting to downloaded music while you are driving (don’t do this)!

Disclaimer: both the author of the article and the OP for this post (me) work for Ably.

The post compares two cloud pubsub services: Azure Web PubSub and Ably in terms of ease of development, creating a collaborative multi-user pixelart drawing app with both services.

Conclusions: Both Azure Web PubSub and Ably offer a similar pubsub feature set, but the Ably API was easier to use (although comes with the disclaimer that the author has used Ably more in the past).

Being able to publish named events and subscribe to them (client-side) without the need of handling them via an upstream server and custom event handlers was an advantage, while a potential downside is the use of a third party library increases the download size of the app.

I've worked from home for years and agree with much of this. It isn't just the "office at home" it's a totally different mindset. It's probably only in my most recent job that I've really _got_ that, and that is because my company is fully remote so everyone is doing it. Nobody feels left out by being at home, and nobody expects synchronous communication or presenteeism.

Thanks for posting this. Full disclosure: I'm the author. I also work for Ably, which is what the post is about, and I'm a content writer so there is inescapably some marketing in it.

But I hope it's valid because, if you try to build a multi-region system for low-latency data transfer across regions, there are issues like discovery and synchronisation to consider.

I think it may be interesting to see how Ably is architected so its pub/sub messaging is realtime and reliable.

For example, how do the EC2 instances in one region find those in another? How does a published message in one region get to a client subscriber in another?

>>"After 50 one begins to recognise in oneself a growing resistance to change, if only because it so often nullifies years of hard-won training"

This really struck home to me. It's true: we teach ourselves life hacks and gradually they become redundant as different life skills are needed.

Short answer is infrastructure for event-driven architecture that is close to the edge so it can distribute events with low latency.

Longer answer is to take a look at some of the Ably blog posts linked in the post here, since they'll explain why Gartner have named this as a category for event-driven brokers.

Thanks

Thanks for your feedback! I'm not sure I said it's a good user interface (I'm not a visual person so wouldn't have the confidence) but I do think it's a good example of a set of features that show a community interacting in realtime. Maybe I didn't make that clear in the article so I'll bear in mind for future writing. TY!

Thanks for your feedback. Could you elaborate a little? I'm not being snarky -- I came up with them based on similar things I'd seen online and I'm not great at visual communication, so if you've improvement suggestions, I'd genuinely like to hear them.

I'm the author of this article and would appreciate any feedback/thoughts. I included just a few examples on the graphic (mostly from memory as I was lucky enough to come of age in 1990 so lived through it).

I remember when Yahoo mail came along with AJAX and how astonishing it was to not have to refresh to get new mail. Although, over a dial up connection, I'm not sure how "realtime" anything was :)

>Were the metrics accidentally omitted?

Not accidentally omitted; we didn't share them because they're not that meaningful without full context of how Ably works internally. The data was useful to the Ably team as they made a decision about whether Graviton would be suitable. It may be possible to share the information anyway if you're interested. I'll find out...

Hey! I'm the author of this article. I work for Ably, so this could be seen as self-promotion but I thought/hope you may find it interesting.

If you want to know more about our Graviton2 migration, or Ably, AMA.

I've noticed that too. I went to the ER with a dog bite and the triage nurse was keen to know if I was a medical doctor before she looked at it.

Was it just me that misread the title initially? Though I think I'd probably be equally good at recognizing human faeces as I've worked my way through a bunch of pets and kids and consider poop my specialist subject.

The point about fracking stands though, right? Isn't the argument that we may have to cause some environmental damage in the name of plentiful, cheap energy? Then that energy gets harvested and, guess what, it isn't plentiful or cheap either.

This was a great blog post from some reddit engineers a few months ago https://www.reddit.com/r/RedditEng/comments/pfgz4r/reddits_n... which talks about how they added a realtime feature, how they did it and how long it took. There was a big fail the first time they rolled it out too...this stuff isn't easy.

Of course, reddit is a huge company and has loads of established engineers. YMMV.

Got any questions? Please just ask -- the post author will be checking here and happy to answer them.

I think it grows on you. There's a way to work with it and if you settle on that, it makes it easier than fighting against the prevailing tide. I find I spend a lot of time looking up opaque build errors but that is partly because the contributing authors aren't all that familiar with it, so their markdown is less than 'pure'

Very helpful - thanks! I completely agree with the calls to action: I've found them inauthentic and jarring. It's a bit like carefully planning an outfit, then throwing some Crocs on at the last minute to serve as footwear! I'm off to spend the rest of my day reading Ken Shirriff's blog :)

Thanks, that's a really helpful list. Getting the goals right is, I agree, a bit part of the answer.

Basic markdown and Sphinx to build into HTML, publishing via github pages. It's an open source project so putting the docs alongside the code just makes sense. Although Sphinx isn't great for my money, it gets the job done.

It’s not unusual though. Most newspapers and magazines make punny headlines and captions to their graphics. Have you read the Economist? Their puns are exquisite and only add to the reading experience IMHO

Thanks for the post -- I'm the author and came here to put it up.

My goal in writing this was to use an analogy because, although it's not a difficult concept, there are a few variations (broker or not, message stream) and I wanted to pull them all into one explanation.
