After setting up some honeypot traps for bots in @rocketvalidator , we've automatically blocked 5 IPs in 2 hours using @paraxialio

My new hobby is watching how the list of bots caught in the honeypot trap grows :D 🤖🍯🕸️ 
And, it works. Normally we get one or two fake user registrations per hour in @rocketvalidator (users that after signing up don't really use the app) - after setting up the honeypot traps in @paraxialio, we haven't seen a fake user since 8 hours ago 💪

测试了半天，chatGPT实现小需求、修Bug、用TDD写代码、多语言实现都没有问题，甚至注释都给你写好了，这些代码大部分情况都是可以直接work的。虽然能力可能不及senior的程序员，但是一般Junior的程度可能真到了，或者很快就到了，以后接卡实现需求甚至直接commit代码都很完全有可能发生🤯
Want to test @opentelemetry spans in Elixir?
Let's say you have a function like the one below - one span, some attributes.

Next, configure your test environment, setting the exporter to undefined and minimizing the batch processor's delay.

Now we're ready to test!
We extract the span record from the opentelemetry dependency, and set the exporter to send the span to the test process.
Then we can assert we received the span from the :otel_exporter_pid, and can test that our attributes are set as expected.

Macros can be used for powerful code generation. They can save time, reduce boilerplate, and produce elegant APIs. To realize the power of macros, remember that most of the Elixir Standard library is implemented as macros.

You have the freedom to extend the language and implement your own desired features. Macros allow you to create your own keywords and allow Elixir to be flexible for future requirements.

Ever dream of having that one cool feature in your language of choice? With luck, you might see it in a few years, more likely never. However, Elixir is different. Through metaprogramming, Elixir allows you to extend the language and create first-class features.

Most programming languages have an AST (Abstract Syntax Tree), but it's hidden from you. When compiled or interpreted, the program's source code is transformed into a tree structure before being turned into bytecode or machine code.

I've been spending my time recently updating the Axon training API to mirror the functionality of the amazing @pytorch_ignite library. You can check out the new API here: github.com/elixir-nx/axon…
If you are remotely interested in Elixir or neural networks or both, I would be very happy if you helped me out by testing out the API with some fun examples and providing feedback, reporting issues, etc. :)
Also, I tried to be as thorough as possible with explanations in the documentation. If anything is unclear, please let me know!

What is Erlang?🧵0/17
#myelixirstatus #elixirnewbie
Erlang is a general-purpose development platform that supports concurrency, scalability, fault-tolerance, distribution, and high availability. It was built in the 1980s by Ericcson, a Swedish telecom giant. However, it is not specialized for telecom systems.

Erlang powers large applications such as WhatsApp, the Riak distributed database, the Heroku cloud, the Chef deployment automation system, and the RabbitMQ message queue.

Raspberry pi is a great way to get your start in IoT, and Nerves and Livebook take that even further. Cool enough: the first real Elixir code Lars wrote was for the Rasberry Pi Zero.

You can sandwich a Rasberry Pi and an eInk display together. The Rasberry Pi runs your application and your application can use The Libraries Inky and Chisel to write to the display.

Bottom line, before the end of September, if you are on Elixir OTP 23 or 24 you should upgrade to the latest patch.
specifically OTP 23.3.4.5 or OTP 24.0.4
specifically OTP 23.3.4.5 or OTP 24.0.4
If you are on an OTP version older than 23, the good news is you will be unaffected so long as you do not upgrade your dependencies. You can freeze your dependencies in order to buy yourself time to upgrade to OTP 23 or 24.

By far the most loved library on the Panel today was Telemetry. Telemetry powers monitoring and observability in elixir projects and provides a consistent interface to do so. Other mentions were OTP, Livebook, and site_encrypt.

1. The endpoint will start several children, we only focus on server and socket here:
* socket children
pool supervisor + a bunch of dynamic supervisors which will eventually start channel servers
the number of dynamic supervisors is the number of CPU cores of your server

The ranch listener supervisor will start a connection supervisor and an acceptor supervisor.
The acceptors will handle connection creation requests.
A cowboy server process is created after a connection is accepted.

The adapter server is also the PubSub shard, they exist to broker broadcasts across the cluster, and relay those messages to local node subscribers which are recorded in the ETS table in the registry.

I...almost completely forgot about giving this talk. I think I may have repressed it. I suppose now would be as good a time as any to talk about why. #MyElixirStatus
The last enjoyable thing I did * for me * was attending Lonestar Elixir Conf 2020. Immediately afterwards came shelter-in-place, the end of a contract gig, and the beginning of a lot of uncertainty for my family. We quickly found ourselves fighting battles on multiple fronts.
I was elated to be asked to give a talk about LiveDashboard. Unfortunately the conference was only a few short weeks after the murder of George Floyd and a period of the greatest civil unrest of my lifetime. My mind was anywhere but on this talk. I did my best to be excited...
I decided to *keep* my book both open-source and freely available online. IMO this the only way to prolong its value for the community, and I can make continuous maintenance of it sustainable 🚀

(2/11) In the past couple of days, I had conversations on the topic of monetizing the open-sourced book🤔. In the end, a lot of effort needs to be put into writing the book, and then continuous updating requires dedication and commitment(similar to any other open source project).
(3/11) The theory is that making the book open-source and freely available to read online will cause me to lose all potential sales profits. I believe that nobody should be banned from benefiting from it because of a lack of financial resources, so I can't sell it.
I’ve been interviewing a lot lately. Some good leads, but I don’t like to put all my eggs in one basket. Today, I took a call from a CTO supposedly looking for an Elixir developer... ( #myelixirstatus )
He was indeed looking for an Elixir dev, but then proceeded to explain how he found that Elixir devs were typically subpar compared to Clojure devs, who were typically experts in data flows. Elixir was also apparently fundamentally flawed, and the Actor model was ridiculous.
The previous CTO who he replaced had build their old stack in Elixir, and apparently it was so bad that they had to start from scratch with a “legitimate” tech stack featuring Clojure and its genius devs.

2/3 #LiveView is *smart* because the abstraction is perfect: your page is a function over state, based on an event.
That state can change in a conceptually sound way, over OTP, through processes and message passing.
It's a highly productive framework for *developers*.

3/3 #LiveView is *fast* because the framework knows how to send down *exactly the right bytes* based on the LiveRender commands.
You can't do this as well without the beam, because each user needs their own process.
Not much data yet but it will be highly *cost effective*.
