I would really like to replace Evernote with a self-hosted solution. Wallabag is one alternative that’s pretty attractive. It’s open source, supports imports and exports, and nice on the eyes. What’s currently holding me back is the lack of an Evernote importer (I kind of expect that, and am eagerly looking forward to writing an
I wanted a directory and everything under it to always get the same owner, group and mode, regardless of who created the files. Access Control Lists to the rescue. [crayon-64cebc27d9da9535756357/] I had to apt-get install acl to get the setfacl command. I’m not exactly clear on why I repeat two regular ACLs with the “d:”
I was curious to see how quickly I could transfer files to my Pi using SSH rather than FTP. Obviously using FTP is way faster than almost any other method, but still I wanted to see how fast I could transfer data over SSH. Here’s the time it took to transfer a 50 MB file
The usual suspects failed me last night when the $DISPLAY environment variable wasn’t being set after I logged in via SSH to my Pi. The usual suspects being to make sure that the X11 forwarding options were turned on in /etc/ssh/sshd_config on the server and in ssh_config on the client, or to use the command

From the manual: [crayon-64cebc27db809682125859/] I had two CSVs, baz01.csv and baz02.csv. They shared the same first column, which was a list of database table names. The second column contained the number of rows from each table. The row numbers between the two files were different, and I wanted to compare them. The join command to
This post on a product designer’s foray into making a much more Earth-friendly concrete gives me hope for humanity. It’s estimated that about 5% of greenhouse gasses are released due to the existing process of making the cement in traditional concrete. The new process, dubbed “Dupe,” uses approximately none (although I’m sure a fair amount

So I was trying to contribute some cycles to the Folding@Home project recently, and ran into a problem that took seemingly forever to figure out. The log.txt file showed that the core (the build of the executable that’s optimized for a given platform) wouldn’t download. [crayon-64cebc27dbebc114119476/]
