Lately I was searching for mobile notebook that I could use for remote work. I checked f ThinkPad series but they were huge bricks that have nothing in common with ‘mobile’ word. Then I saw ASUS Zenbook that I didn’t take into account before and it was exactly what I was searching for. Configuration of Skylake based notebook right now is not straightforward - there are still glitches and small bugs that are waiting to be fixed....
I try to use IPv6 where it’s available but it’s sometimes so hard… It happen quite often that I can’t download packages from repos because they weren’t configured on IPv6 vhosts even when host is available via IPv6 address. For APT you may use this trick to force IPv4 connections only: echo 'Acquire::ForceIPv4 "true";' > /etc/apt/apt.conf.d/99force-ipv4 If you need more than that, then gai.conf will allow you to filter where you will be connecting via IPv4 and where via IPv6 - in example bellow you will prefer IPv4 whenever it’s available:...
Sometimes it’s easier to use octal file permissions but they’re not so easy to list. I caught myself few times that I didn’t remember how to list them - so this is a reason for that note. stat -c "%a %n" * 755 bin 755 games 755 include Yes, it’s that easy 😃 And here also with human readable attributes: stat -c '%A %a %n' * drwxr-xr-x 755 bin drwxr-xr-x 755 games drwxr-xr-x 755 include
I was configuring WordPress with HyperDB external link plugin on PHP 7.0 but the only I get were constant 500 errors. As I found here external link PHP 7.0 is not supported by HyperDB for now - it’s rely on mysql php extension but in PHP 7.0 there is only mysqli extension. But few folks fixed it and it’s possible to use it. curl -O https://raw.githubusercontent.com/soulseekah/hyperdb-mysqli/master/db.php mv db.php /var/www/wordpress/wp-content/ And configure it ex....
I’m playing a lot with Docker lately. Building images, and then rebuilding, and then building again… It’s pretty boring. To automate this task a little I used inotify to build automatically after I changed any file. This trick could be used in many different situations. You will need inotify-tools package: sudo apt-get install -y inotify-tools Then run something like this: while inotifywait -e modify -r .; do docker-compose build; done This commands will rebuild my Docker images after any file change in current directory....
I never tried it before but today I needed to install WordPress… From command line only. And there is a way to do this with wp-cli external link . WP-CLI installation First some requirements (as root): apt-get install php5-cli php5-mysql mysql-client curl And now installation of wp-cli (as root too): curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar chmod +x wp-cli.phar mv wp-cli.phar /usr/local/bin/wp Check if it’s working: $ wp --version WP-CLI 0.22.0 WordPress installation Now you should switch to user of your web application, ex....
When I started playing with Docker I was running a lot of commands to build image, delete containers running on old image, run containers based on new image, etc… A lot of log commands with links, volumes, etc… Then I started searching for something to automate this task and here I get to docker-compse command, this is how you may install it: pip install docker-compose And install additional bash completions (run as root):...
I’ve played with Docker a little in it early days but didn’t stick for longer with it. It’s stable now so I wanted to check how it’s running now. I really can’t accept this method of installation: curl -fsSL https://get.docker.com/ | sh I think that world is going to it’s end when I see such scritps… I prefer to do this manually, knowing exactly what I have to do. Install prerequisites:...
I started playing with Docker and here I will write some commands that where not so obvious at beginning 😃 List running containers: docker ps List also not running containers: docker ps -a Remove all containers (be careful with that): docker rm $(docker ps -a -q) Remove all images: docker rmi $(docker images -q) Docker won’t remove any old volumes used by containers, so after some time you may be interested in deleting them all:...
I was doing a lot of changes to my old posts, switched to HTTPS, etc. Sometimes it was useful to change some particular text in all my old posts at a time, but there is no such feature in WordPress. But WordPress runs on MySQL and I could use SQL query to update such posts. Make backup - it’s not required but strongly advised 😃 Now use this query as template to replace in place whatever you need: ...
