I’ve found that the best way to avoid ad-infested apps for exercising is to use official apps from popular brands. They’re better because they bother you again and again about non-exercise-related matters (ads, social sharing, etc)
For example the following apps are great alternatives to popular ad-filled apps:
I was trying to install some GitHub repos as dependencies using composer. Composer kept getting stuck on installing the private ones.

Composer should work much more smoothly now.
When you generate a SSL certificate for an nginx site through the Virtualmin interface for a virtual (sub-)server, the button “Copy to Webmin” incorrectly triggers the “Copy to Usermin” feature.
On the other hand, the Webmin interface to generate the SSL certificate also fails, because it does not allow for generation for nginx hosts (only Apache hosts).

virtualmin install-service-cert --domain yourdomain.com --service webmin |
Are you getting a “challenge did not pass” error? Can’t find a matching hostname for your Webmin panel to generate Let’s Encrypt certificates to?
The trick is that Lets Encrypt only works with Apache. Most Webmin/Virtualmin panels are running on miniserv Perl scripts on port 10000. We must follow the following steps:
1. Create a virtual server (or sub server) for the matching domain in Virtualmin.
2. Go to Webmin > Webmin Configuration > SSL Encryption > Let’s Encrypt
3. Request Certificate for “Apache virtual host matching hostname”. Set renewal for 12 months!
There are quite a few tutorials out there to turn Raspberry Pi into Digital Signage or Kiosk solutions. I’ve used elalemanyo GitHub gist to run Chromium browser for my Digital Signage needs. It provides lots of options and combines various sources of information. There are options for other browsers on that page.
The gist does not address a way to automatically reload/recover from page/chrome/connection errors. You can use the following two extensions to recover from these problems:
1. Oh No You Didn’t extension will automatically reload tabs that have crashed (Aw Snap! He’s Dead Jim etc.). Handy for Kiosk mode where access is limited. This helps recover from memory related problems (quite often the Raspberry Pi’s are limited by memory or CPU).
2. Autorefresh on Error will auto-refresh a page after 60 seconds if page did not load. This is handy for any webpage that changes often and needs to be refreshed. And for places where the WiFi coverage may not be ideal, especially on boot.
Sometimes out of dire circumstances one may download a huge set of rars. Unraring all the scene release files in split rar format in each separate directory with their separate subtitles (idx/sub files) is a cumbersome task.

find /path/to/dir-of-rars -iname "*.rar" -exec sh -c 'dir=`dirname {}` && echo "$dir" && unrar -o- e "{}" $dir' \; |
Update on December 26, 2016: Latest Raspbian can install Chromium Browser by just doing: apt-get install chromium-browser. No need to download debs or run gdebi. Making this post obsolete.
Installing the latest Chromium browser on Raspberry Pi B models is a hassle. Although the following tricks work on the other Raspberry Pi models. I wanted to target Raspberry Pi B+ with this tutorial since it requires some special steps.

At two recent WordPress conferences, WPCampus 2016 and WordCamp Boston 2016, I gave a talk along with Andrew Bauer on using WordPress as a Service (WPaaS) in a higher education setting.
In this talk, we covered the organizational and technical benefits of running a multi-network, multi-site WordPress as the primary CMS at Boston University. We highlighted specific strategies, including organizational policies, development workflows and team structure that allow us to serve over a million users per month. We’re here to help dispel the notion that a centralized approach to WordPress can’t successfully be implemented in higher ed.

Solution
Wait for Pulsar to start up. It usually takes about 1-2 minutes for it to load after Kodi has been enabled.

I was recently trying to insert imported data into WordPress. When trying to insert it into WordPress using wp_insert_post, I was receiving the following error:
|
1
|
Could not insert post into the database |
It turns out that I was trying to insert data in a non-utf8 encoding, whereas WordPress uses UTF8 internally. All I had to do was run the following PHP function to convert it over to UTF8:

$post_content = iconv('ISO-8859-1','UTF-8', $post_content) |
