Shopping List

DeLonghi Dedica EC685.M (~100€)
1. Steam Wand (29,49€)
2. Portafilter (46,99€)
Comandante C40 Mk4 (Virginia Walnut) (249€)
WDT Tool (11,99€)
Tamper (29,90€)
Milk Frothing Pitcher (9,34€)
Knock-Box (22,95€)
Loveramics Cup Egg Ice Blue (11,90€ per Cup)

Upgrading DeLonghi Dedica

The Steam Wand and the standard Portafilter of the DeLonghi Dedica a pretty limited in their capabilities. Since the portafilter contains pressurized baskets, this leads to a worse quality in coffee. Additionally in my opinion, the new wooden portafilter has a better astetics and is easier to clean, because parts can be taken apart.

Upgrading the Steam Wand

The steam original steam wand is bad to clean and makes it more difficult to get good results in latte art. As the upgrade of the portafilter is rather trivial, the upgrade of the steam wand requires taking the whole machine apart.

There are several tutorials online on how to exchange this. I’ve taken the first one for the installment:

Known Issues

During replacement of the steam wand I wasn’t that careful and overstretched the connecting rubber tube. There are dealers online having replacement parts on this, if this rubber band might fall off due to the pressure.

Upgrading the Comandante Grinder

When doing espresso, some types of coffee require fine adjustments in the stages of grinding. The Commandante Red-Clix double the amount of stages in the grinder, what allows better results in brewing.

Test your machine

My personal favourite coffee right now is the supremo vulcano. I recommend XXX clix on the commandante and 30 seconds of brew time on the Dedica.

Last words

In total the whole setup has cost me ~500€ what is definitely not cheap but resulting in a great experience of enjoying good coffee. There are definitly retailers that enable some cost saving, but the grinder is pushing the price with 250€ the total setup price highen than with a budget solution. I’m kinda unhappy with the knock-box, but maybe there are some better alternatives on the market, that I can try out.

Set Password for Proxy page

You need to pase the output in line 43 of the Docker-Compose file.

echo $(htpasswd -nb username password) | sed -e s/\\$/\\$\\$/g

Example:

- "traefik.http.middlewares.traefik-auth.basicauth.users=test:$$apr1$$.LOxTF4y$$/OjdUK3pSGiT/flYY42uS1"

Install Latex Packages

First of all, the package manager must be installed including all Latex Packages. The package manager of Latex is called tlmgr.

Start Docker-Container:

sudo docker-compose up -d

Create User:

Enter your own E-Mail address to this command

docker exec sharelatex /bin/bash -c "cd /var/www/sharelatex; grunt user:create-admin --email=max@test.com"

Install Packages:

If the Sharelatex Container is running enter following commands

sudo docker exec sharelatex wget http://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz
    sudo docker exec sharelatex tar xvfz install-tl-unx.tar.gz

Then open the Bash Console of the container with the command:

sudo docker exec -ti sharelatex /bin/bash

Change directory: cd install-tl-XXX
Change rights: chmod u+x install-tl
Run ./install-tl
Wait until everything is installed
exit the Bash Shell of the container

Update Packages:

Now check the tlmgr (Latex Package Manager) for updates

sudo docker exec sharelatex tlmgr update

Important Docker Commands:

Start Container:

sudo docker-compose up -d

Run without -d if you want to see the console output.

Stop Container:

sudo docker-compose down

Reload Docker-Compose File:

When Container Stopped

sudo dokcer-compose up --force-recreate -d

Make directory newcerts
Download this git in the directory wget https://gist.githubusercontent.com/corusm/f36fc12022668ee1972f004fd46385f6/raw/9da0364cd40deb4ebac50a173cedae0c636f218c/docker-compose.yml

Host Sharelatex in Docker (with HTTPS)

corusm — Thu, 03 Dec 2020 23:17:26 +0000

This guide is about setting up Sharelatex in a Docker container with https connection.

Install Docker

Here two examples of installing the Docker deamon. The required Packages are docker and docker-compose.

Arch Linux

yay -S docker docker-compose

Debian / Ubuntu

curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh

Enable Service

To enable the service as background task simply run

sudo systemctl enable docker
sudo systemctl start docker

Setup Sharelatex Container

1. Create Virtual Docker Network

sudo docker network create main

2. Configure Docker-Compose File

In the Docker-Compose File you must change several values to your custom needs.
The specific lines to change are commented.

3. Set Password for Proxy Page

You need to paste the output in line 43 of the Docker compose file.

echo $(htpasswd -nb username password) | sed -e s/\\$/\\$\\$/g

Example:

- "traefik.http.middlewares.traefik-auth.basicauth.users=test:$$apr1$$.LOxTF4y$$/OjdUK3pSGiT/flYY42uS1"

4. Install Latex Packages

First of all, the package manager must be installed including all Latex Packages. The package manager of Latex is called tlmgr.

Run Docker Container:
To run the Sharelatex Server enter

sudo docker-compose up -d

Create User:
Enter your own E-Mail address to this command

docker exec sharelatex /bin/bash -c "cd /var/www/sharelatex; grunt user:create-admin --email=max@test.com"

Install Packages:
If the Sharelatex Container is running enter following commands

sudo docker exec sharelatex wget http://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz
sudo docker exec sharelatex tar xvfz install-tl-unx.tar.gz

Then open the Bash Console of the container

docker exec -ti sharelatex /bin/bash

Change directory: cd install-tl-XXX
Change rights: chmod u+x install-tl
Run ./install-tl
Wait until everything is installed
exit the Bash Shell of the container

Update Packages:
Now check the tlmgr (Latex Package Manager) for updates

docker exec sharelatex tlmgr update

Important Docker Commands

Start Container

sudo docker-compose up -d

Run without -d if you want to see the console output.

Stop Container

sudo docker-compose down

Reload Docker-Compose File

When Container Stopped

sudo dokcer-compose up --force-recreate -d
