# It's only a POC for now

  @moduledoc """
  Abstracts away common schema functions, such as list, get, create, update, delete, etc.
  Assumes that the schema module has a `changeset` function.
  
  Usage:
    defmodule MyContext do
      use ContextBase, repo: MyApp.Repo, schema: MyApp.MySchema
    end

Automating Daily Reports, because fuck it, really...

Each day at our company, developers are required to document their activities, painstakingly jotting down their daily work and future plans. A monotonous chore that I just really dislike.

So now, there's a scribe for that :

Poor Man's Global Traffic Manager

Sometimes we need to add redundancy to some service or server which happen to be a public-facing entry point of our infrastructure. For example, imagine we want to add a high availability pair for a load balancer which sits on the edge of network and forwards traffic to alive backend servers.

What you will need: Server behind NAT (Server A), Server with static ip e.g. VPS for hosting Wireguard (Server B).

1) On your server B paste this commands in terminal: curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh && chmod +x wireguard-install.sh && ./wireguard-install.sh
2) Create new client and save his ip. Mine will be 10.66.66.123 
3) Download this config to server A and connect to your server B with wireguard.
4) Depending on your client ip which we configured in step 2 type this commands in server B terminal (this time I wanted my Minecraft server exposed, so I chose 25565 port, yours can depends):

sudo iptables -P FORWARD DROP
sudo iptables -A FORWARD -i wg0 -o eth0 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
sudo iptables -A FORWARD -i eth0 -o wg0 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT

Programming as Theory Building

Peter Naur

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

r0xsh

public static byte[] readUri(Context context, Uri uri) throws IOException {
    ParcelFileDescriptor pdf = context.getContentResolver().openFileDescriptor(uri, "r");

    assert pdf != null;
    assert pdf.getStatSize() <= Integer.MAX_VALUE;
    byte[] data = new byte[(int) pdf.getStatSize()];

    FileDescriptor fd = pdf.getFileDescriptor();
    FileInputStream fileStream = new FileInputStream(fd);
    fileStream.read(data);

Demo

What demos are?

A file type (with the .dem extension) containing recorded events that can be edited and played back in-game. Demos can be edited to change camera angles, speed up, slow down, play music, and other functions. (from Valve wiki)

Benefits

• You have your every game archived once enabled. Something nice happened to game? You can always get back to it!
• It takes way less size than a video and about no system resources compared to its recording.
