Telegram save all media from chat/user/channel

Quick tip. It is possible to download media with small python script.

Goto https://my.telegram.org and generate api id and api hash Install Telethon library with pip3 install telethon Run saveAllMedia.py (replace api_id, api_hash and username with your values).

If you need proxy install https://github.com/Anorov/PySocks pip install PySocks

This code downloads all media from the dialog with username user/chat/channel in current directory.

Walkthrough of what I did to increase performance on my Synology NAS box during an expansion, and afterwards.

Performance on Synology RAIDs

(especially while expanding)

Warning: The exact commands may not match for your particular linux OS / Synology(NAS) device. I had to customize the commands after exploring my particular system's setup.

If you're new to linux, or this is a new piece of hardware / a new synology device, jump down to the section called "Inspecting a setup"

An example with an oneshot service on systemd. #systemd #systemd.service #oneshot

README

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

# log the default values:
echo "speed_limit_max: `cat /proc/sys/dev/raid/speed_limit_max`" #=> 200000
echo "speed_limit_min: `cat /proc/sys/dev/raid/speed_limit_min`" #=> 10000
echo "stripe_cache_size: `/sys/block/md2/md/stripe_cache_size`" #=> 256
# update to use more RAM (Stripe Cache Size) and higher lower bound (speed_limit_min)
echo 100000 > /proc/sys/dev/raid/speed_limit_min
# This will result in more memory usage. bumping to 32768 resulted in ~512MB RAM increase.
echo 32768 > /sys/block/md2/md/stripe_cache_size

Resource Allocation in Docker

#Container Resource Allocation Options in docker-run

now see: https://docs.docker.com/engine/reference/run/#runtime-constraints-on-resources

You have various options for controlling resources (cpu, memory, disk) in docker. These are principally via the docker-run command options.

##Dynamic CPU Allocation -c, --cpu-shares=0
CPU shares (relative weight, specify some numeric value which is used to allocate relative cpu share)

package main
import (
"net/http"
"database/sql"
"fmt"
"log"
"os"
)
