So is it worth using it? So far my favourite grep replacement was ack. It’s author created a nice grep tools comparison page.

I have tested just the raw speed of grep vs ack vs rg (ripgrep). ripgrep was fastest, likely due to the fact that it searched my whole directory using several threads in parallel. Any way - there you go - switch to “rg” utility:

sudo apt install ripgrep

“Once men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them.”

sudo apt install -y pkg-config build-essential autoconf bison re2c libcurl4-gnutls-dev libxml2-dev libssl-dev libzip-dev libzip4
git clone https://github.com/php/php-src.git
cd php-src
# Take the latest PHP 8.4 tag
git checkout PHP-8.4.6
# Clean up the repository from any temporary build files.
git clean -Xdf
# Build PHP
./buildconf
# With few useful extensions
./configure --disable-all --with-curl --with-iconv --enable-dom --with-libxml --enable-phar --enable-filter --with-openssl --with-zip --with-zlib
make -j4

You can then install PHP in the system with:

sudo make install

Or simply use the executable, CLI is located under ./sapi/cli/php.

If you’re doing local development, then xdebug is a must, let’s add it as well.

git clone git://github.com/xdebug/xdebug.git
cd xdebug
# Let's make sure we're using PHP we just compiled
/usr/local/bin/phpize
./configure --enable-xdebug
make
make install

To confirm you have the right PHP with xdebug review the output of:

According to Self-Determination Theory by Csíkszentmihályi, there are three basic psychological needs that drive human behavior (and intrinsic motivation):

• Autonomy
• Competence
• Relatedness

Idea from Strava: You can win medals in certain segments, and when I know I am close to beating a time in a segment, it motivates me to push myself harder.

Idea from Duolingo: Chests may contain rewards such as double XP for the next 15 minutes, a reward that encourages users to keep learning for another 15 minutes, earning extra XP to climb the leaderboard, but also keeping the user learning for 15 more minutes.

Technology drivers of change:

• Quantum computing
• AI and machine learning
• Biotechnology and gene editing
• Augmented and virtual reality (AR/VR)
• Advanced robotics and automation
