cowboy VS Apache Log4j 2

According to the 'Server' response header, Cowboy is the customer facing web server https://github.com/ninenines/cowboy

===> sh(git clone -n https://github.com/ninenines/cowboy .tmp_dir636214859401) failed with return code 128 and the following output: Cloning into '.tmp_dir636214859401'... fatal: unable to access 'https://github.com/ninenines/cowboy/': SSL certificate problem: unable to get local issuer certificate

RE: HTTP/Web Sockets/TCP/UDP/etc. - check out NineNines libraries: Ranch (TCP Socket Acceptor), Cowboy (HTTP Server), Gun (HTTP client), and CowLib (General HTTP/SPDY library) are pretty good from what I hear.

Ranch is a pretty well optimized and battle hardened tcp acceptor. It powers the Cowboy/Phoenix server which scales to extreme level of concurrency and low latency. Cowboy uses ranch to pool and accept connections and I believe it uses {active,once}.

I have a web application which uses cowboy and cachex every so often cachex errors, which means my server returns a 500.

Cowboy is a small, fast and modern HTTP server for Erlang/OTP.

plug_cowboy: Uma implementação do Cowboy para o Elixir.

We are going to be using the light http server Cowboy and the adapter Plug to return our data.

At the core of your web app (and any other app that works with HTTP) will be Cowboy, but further than that, you need to know what a web app consists of and pick your tools for each layer separately.

I don't think that's a good example. While Apache devs are volunteers and Microsoft devs are employees, they were criticized for their slow response time and seeming lack of urgency until it was far too late.

The official website. The vulnerability was introduced in 2.0-beta7 which was released in 2013.

However, there are many open source projects that are widely used but not well-known, including cURL, ImageMagick, MyCLI, Homebrew, Apache Log4j, and OpenSSL. This article will take a closer look at these unsung heroes of the open source world. I do not want to give them a business model or financial advice in this article. This largely depends on the author's personal experience and values. I just want to raise more awareness about these open source projects.

What you need is log4j-core, what you downloaded is some kind of connector between log4j and JUL. Tbh I don't know what JUL is, but that's not important. You can get log4j-core on from the official website - https://logging.apache.org/log4j/2.x/ or in maven repo. In case you're not using maven, I highly, highly recommend you using it for managing your dependencies.

> The Apache Software Foundation, which maintains the open-source tool, quickly released a patch...

Apache horribly mismanaged this and did not release a patch until it was already widely known and being exploited in the wild. They also messed up and had to release several subsequent patches to actually fix the vulnerability.

Remember: this vulnerability was disclosed to them in November.

Think back to the Log4J event, were you affected? (https://github.com/apache/logging-log4j2)
