Recently I had a look at tofu library.
Initially it seems this library provides granular typeclasses which provides developer to implement high level logic and substitute corresponding lower level implementation as proposed by tagless final approach.

But env module, for example looks overcomplicated but tecnhically provides reader monad. Definitely this is an acceptable approach, but it seems that monix task dependency introduce all this complexity. Why env contains any side effect specifics?

There are some options to control application memory consumption.

Docker has a couple of flags to control application inside the container.

1. –memory flag defines non swap memory limit
2. –memory-swap flag defines total memory limit (swap + non swap memory) Details can be found here

Moreover, there is a cgroups limit at the os level. To check it

    cat /sys/fs/cgroup/memory/memory.limit_in_bytes

When you try to check is, in some situations you can see some huge magic number

There is a nice python library addict which is interesting for a couple of reasons.

First of all, it simplifies creating a nested dictionary (see readme).

Secondly, it represents an another nice example of using python magic methods.

There is interesting end-to-end delay-based congestion control algorithm Copa.

Here you can find the details.

Facebook tried to use it and results seem very promising.

Let’s suppose you want to format flash drive but while you are trying to start formatting you see an error like this ‘The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes’.

Moreover, partitions can not be removed using neigher gnome disk nor gparted.

In that case you can use fdisk with privileged access:

    fdisk /dev/sdX

To show partition you can use ‘p’ command, to remove partition - ‘q’ command.

Here is the site of the project.
Custom pipelines can be defined as code.

Here is the library that allows you to call python code from clojure.

Here is the description of a bunch of JVM’s flags and some recommendations how to use them.

A couple of links about commit convensions:

1. commit generator
2. Convensional commit specification

Here is nice collection of 8-bit ui controls.
Framework based on css, so you can used it with any js code.
