When names, product descriptions, addresses, or CMS content become garbled after a MySQL migration, the dump file often gets blamed. The real problem may have started earlier: incorrect bytes in the source, a mismatched dump connection, a restore using different assumptions, or simply a tool displaying the file with the wrong encoding.

I have a thinkpad laptop with a touchscreen. When I connect my external screen, then the touch sensor on my laptop screen moves the cursor on the external screen, which is not what I want. I want to keep my touch on my laptop screen.
I followed the instructions here: https://askubuntu.com/questions/51445/how-do-i-calibrate-a-touchscreen-…

I did not have any problems on my main machine, but my old machine which had not been updated for more than a year did not swallow the upgrade easily.
If you encounter this problem when reading csv-files, you might want to try to change the encoding from UTF-8 to latin1. This worked for me when using the tolower function in R.

Running a piece of PHP only on the homepage sounds simple. It may control a campaign banner, lead form, pricing teaser, announcement, or tracking integration. But the homepage is also one of the worst places for a fragile shortcut: query parameters, URL rewrites, staging paths, caching, and CMS settings can all change what “home” means.
Installation on Ubuntu 20.04
If you are running with Apache you can install from dpkg. If not, then it's probably better to install from source.

To detach a process started in the terminal, you can always add & at the end. For example: npm run evaluation &
Or: nohup bash script.bash &
After that you can run "jobs", to see the running jobs for that user.
Otherwise you can use "htop" or "ps -ef |grep bash" to find all bash jobs for instance.

Many times you need to download files from the internet, specifically when you want to automate a process or two. Here is where wget comes in handy. This is a standard tool on most Linux systems.
In some cases the server you want to download from does a couple of checks, so your automation fails. You can come by that by adding a couple of switches like:
wget --user-agent="Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36" --auth-no-challenge URL_OF_FILE_TO_DOWNLOAD

A PageSpeed score is useful only when it helps you decide what to fix. For business owners, the real questions are whether priority pages load quickly, forms respond promptly, and releases stop reintroducing problems. Agencies need to separate template, plugin, hosting, and third-party issues before budget disappears into random optimisation work.
