Passwords on post-it attached to monitor

How to Use Saved Passwords Everywhere

Some web sites and applications prevent users from using previously saved credentials. There a very few legitimate reasons to do so. In the vast majority of cases, such measures just patronize users, often those people that actually keep up the service with their financial support. But it is actually quite simple to bypass such paranoid settings.

Formatting Large Hard-Disks On Mac OS X

My new LaCie rugged USB-C drive showed only a capacity of 372 MB instead of the 4 TB that I had bought, when I formatted the disk on Mac OS X High Sierra. It turned out that I first had to create a GUID Partition Table (GPT) on it to use the full capacity.

Both Dist::Zilla and Travis CI can greatly improve the quality of your Perl distribtions. But using them in combination causes issues. Fortunately, they can be easily solved.
