Development today relies on multiple teams, services, and environments all working in unison. A topic that always comes up, when setting up a new development environment: How do we secure important credentials, while not making it too complicated for the rest of the team?
The key when working with version control systems like Git, is to keep any type of credentials out of the versioning system. These can be API keys, database or email passwords.
Even if its a private repository, development environments might change. It can be a simple staging & live website setup you are maintaining.
The simplest way in PHP is to use .env files to store your credentials outside of the public accessible directory structure. So outside the public_html, but still within the reach of the executing environment to read it. Variables are accessible through $_ENV['yourVar'] or getenv("yourVar"), once included in your code.
To make it simple you can use the popular package vlucas/phpdotenv, which reads and imports the file automatically.
Don’t fool yourself, if an attacker finds a way into your system, these variables can be easily read. This is just hiding the file from public access and provides some convenience while developing or sharing code.
Some people propose to encrypt / decrypt environment variables using a secret key. But if an attacker can access your data, he can also find the secret key.
There are some nice packages that offer just that. You have to decide if those fit your ammo.
php artisan credentials:edit
The Apache2 environment variables are set in the /etc/apache2/envvars file. These variables are not the same as the environment variables of your Linux system; they are stored and manipulated in an internal Apache structure.
The /etc/apache2/envvars file holds variable definitions such as APACHE_LOG_DIR (the location of Apache log files), APACHE_PID_FILE (the Apache process ID), APACHE_RUN_USERS (the user that run Apache, by defaultwww-data), etc.
You can open and modify this file in a text editor of your choice. This is nice, but far from simple and requires a server restart. This is something which helps you when hardening security on a live deployed setup.
There are dynamic approaches, but you can do some research for that yourself :) Skipped that rabbit hole for now …
Handling secrets completely detached is another possibility. This is surely an overkill for most cases, but using an Infrastructure Secret Management concept might be worth looking into, if you are working on bigger scale projects that involve multiple development teams and setups. These services also often deal with secret rotation.
HashiCorp Vault – “Vault is a tool for securely accessing secrets. A secret is anything that you want to tightly control access to, such as API keys, passwords, certificates, and more. Vault provides a unified interface to any secret, while providing tight access control and recording a detailed audit log.”
You can deploy your own vault on your own infrastructure or test out a hosted version, which is free for Open Source projects. HashiCorp Vault
You will find a bunch of Hashicorp related packages that will help you to integrate a vault into your project workflow (scmrus/php-vault-env , poc-webapp-vault).
While this is nice, you will need to cache / store credentials somewhere, as you don’t want to query the vault on every single access.
The Hashicorp Vault is not the only Infrastructure Secret Management solution. There is a nice Github Gist that lists other solutions and a nice feature matrix.
Amazon also provides a solution called AWS Secrets Manager, which makes a lot of sense, when you build and deploy on AWS already :)
I will use this article to collect interesting tips and tricks about using the Linux cron. This is not so much about setting up a cron, but about little things I use or discovered!
The cron daemon is a long-running process that executes commands at specific dates and times. You can use this to schedule activities, either as one-time events or as recurring tasks.
For commands that need to be executed repeatedly (e.g., hourly, daily, or weekly), you can use the crontab command. The crontab command creates a crontab file containing commands and instructions for the cron daemon to execute.
Format is: MIN HOUR DOM MON DOW CMDMinute fieldHour fieldDay of monthDay of weekCommand
Run every 5 minutes
Run yearly, monthly, weekly, daily or on reboot.@yearly will run at 00:00 on Jan 1st for every year.@monthly will run at 00:00 on 1st of every month.@weekly will run at 00:00 on starting of every week.@daily will run at 00:00 on every day.@reboot will run after the server has been rebooted
A real cron does not rely on website activity and executes independently.
Do not forget to disable the virtual WordPress Cron in the wp-config.php!
Gatsby is a free and open source framework based on React that helps developers build blazing fast websites and apps.
While researching some popular static site generation tools, GatsbyJS comes up often. I have played with NuxtJS and Hugo in the past, but what I REALLY like about GatsbyJS is the plugin / modular system. You can build your website with plain-old React and CSS styles, but make your development more efficient by adding node_modules.
Also being able to import any data source with ease, using GraphQL, is amazing. And when it comes to content management, you can easily hook a headless WordPress or Drupal setup into the mix and consume their REST APIs :)
I am not switching my own website to GatsbyJS anytime soon, but its another tool in my toolbox for future project consideration !
There are many tutorials on Youtube about getting started, maybe something to consider for the next freetime testdrive ;) Enjoy …

Verein 3.0 is an e-Learning platform, that is meant to assist people in the creation of new clubs in Germany. Germany has a vivid club culture, but many people are afraid to start their own, due to new legal requirements or too little knowledge of what is actually required.Verein 3.0 offers educational videos, download and online written content to subscribers. The platfom is currently in its preview stages and will open its doors in late summer 2019.

Manet is a REST API server which allows capturing screenshots of websites using various parameters.
The Node.js server can use SlimerJS or PhantomJS as headless browser engines.
I have build similar with CasperJS, but this is far better for those that want a simple straight solution.
A nice set of CSS3 Animations that can be easily used to spice up your design.
Two tools that can enhance your workflow immensely. Enjoy!
“After Meltdown, Spectre, and Foreshadow, we discovered more critical vulnerabilities in modern processors. The ZombieLoad attack allows stealing sensitive data and keys while the computer accesses them. While programs normally only see their own data, a malicious program can exploit the fill buffers to get hold of secrets currently processed by other running programs. These secrets can be user-level secrets, such as browser history, website content, user keys, and passwords, or system-level secrets, such as disk encryption keys.” – zombieloadattack.com
There seems to be a new security related story every day. Read about the latest CPU related issues at CPU.fail.
Since I started in 2002, all iterations of portalZINE have been pure english content websites. You can read about the why on my services page.
I had potential customers in Germany complain about that a lot over the past few years. But your own website often suffers, while your customers get all the attention. That is how it is and how it should be!
Creating Multi – Language websites has been part of my services & portfolio for years, with an extreme application setup handling 13 languages in 2014 for the soccer world cup.
Multi-Language setups have come a long way and it was time to showcase that on my own setup as well. Not only to calm those potential customers, but to testdrive new functionality and possibilities on my own setup. portalZINE has always been my testlab for stability and new feature sets.
Most of my static pages are available in English and German now, the blog itself will remain pure English.
