How to use a TPM on Linux

Prerequisites

Do I have a TPM 2.0?

hi, i'm daniel. i'm a 15-year-old high school junior. in my free time, i hack billion dollar companies and build cool stuff.

3 months ago, I discovered a unique 0-click deanonymization attack that allows an attacker to grab the location of any target within a 250 mile radius. With a vulnerable app installed on a target's phone (or as a background application on their laptop), an attacker can send a malicious payload and deanonymize you within seconds--and you wouldn't even know.

I'm publishing this writeup and research as a warning, especially for journalists, activists, and hackers, about this type of undetectable attack. Hundreds of applications are vulnerable, including some of the most popular apps in the world: Signal, Discord, Twitter/X, and others. Here's how it works:

Cloudflare

By the numbers, Cloudflare is easily the most popular CDN on the market. It beats out competitors such as Sucuri, Amazon CloudFront, Akamai, and Fastly. In 2019, a major Cloudflare outage k

  Abstracts away common schema functions, such as list, get, create, update, delete, etc.
  Assumes that the schema module has a `changeset` function.
  
  Usage:

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);
