If you’ve ever got a long running headless server that gets some amount of use, it will eventually accumulate files and data on the disk until the point where the allocated disk space for the server runs out and you will need to clean some things out. Running df -h tells you it is completely full, but how will you be able to see what is taking up the space?
There exists all sorts of graphical programs to visualise disk usage for various operating systems, but when you’ve got a server that you maybe only have headless SSH access to, your options become quite limited. Fortunately the program QDirStat has a feature that allows you to scan a filesystem into a cache that can be opened and inspected on another system.
Time-based one-time password (TOTP), RFC 6238, is an authentication method commonly provided as a means of 2FA for many services. It is a great alternative to other 2FA methods such as SMS.
It is unfortunately also very misunderstood due to the common misconception that it requires a phone or a proprietary app, but the algorithm is fully open and the process to generate a code does not depend on any external sources other than the fabric of time itself.
If you’ve ever owned a couple Android devices you’re definitively familiar with the kind of pre-installed system “bloatware” apps that may come with it from your manufacturer. Or maybe you’re lucky and only get the base Google apps, or sometimes even that is too much for you.
Rooting your Android device usually makes you able to write to the system partition and delete system apps, but as time has gone on rooting has come with more headaches than the niceties it used to give you. While there are some that still choose to root their Android phone for the freedom it gives, a lot of us who may have done it in the past no longer do so just for the peace of mind of not having to deal with apps that check the device’s “integrity”.
As you’re on your phone you may be downloading memes, files, taking pictures, writing notes and whatnot. But after a certain point you’d want to go through these and move anything you want to keep to your computer since let’s face it, your phone is not for permanent storage.
This blog post shows you how to mount your storage so you can manage it from your computer using SSHFS by running an SSH server on your phone, as well as the motivation for why I manage my phone’s storage this way rather than other traditional methods one may otherwise use.
When developers need to put placeholder strings or values in code, they tend to be very creative in what they come up with. Sometimes it may be obscene and cause issues for their company when it eventually shows up in binaries or released source code. But most of the time it is nothing more than an amusing joke, maybe an inside joke in the development team with a backstory.
Such was likely the case with El Telco Loco, a fictional mobile operator that used to exist as a placeholder name in Android, and was inadvertently exposed to users through a peculiar turn of events.
This is an amusing story about line endings. Originally written as a post for the Voxelmanip Forums, extended and improved as a post on this blog.
Carriage Return, also known as CR, also known as \r, also known as 0x0D, is the bane of every developer working on both Unix-like and Windows systems, as well as the bane of every web developer working with forms.
