Karabiner Elements Linux Software That Is

As with pretty much anything in your computer, it is configurable (and worth configuring).This usually involves some software that is listening and, whenever a certain key is pressed, it intercepts that event and replaces it with another event corresponding to a different key. Hammerspoon (desktop automation on macOS)As a programmer, your keyboard is your main input method. Caps Lock (Control mapped to caps lock at the same time) Mac: Karabiner-Elements, amazing application which lets you do heavy customizations to you keyboard. Karabiner Elements is described as 'Karabiner, previously called KeyRemap4MacBook, is a very powerful keyboard remapper for Mac OS X.

Swapping Ctrl and the Meta (Windows or Command) key.You can also map keys to arbitrary commands of your choosing. Most OSes have a play/pause key. Remapping PrtSc to Play/Pause music. We (the instructors) highly encourage this setting since Caps Lock has a very convenient location but is rarely used.

Remapping on tap vs on hold, e.g. Pressing shift five times toggles Caps Lock. Remapping sequences of keys, e.g. Your long email address or your MIT ID number.There are even more complex modifications you can configure: Inserting some specific text, e.g. Here, some software listens for a specific key combination and executes some script whenever that event is detected.

Karabiner Elements Linux Series Of Processes

Most of them might sound unfamiliar but are responsible for core parts of the system such as managing the network, solving DNS queries or displaying the graphical interface for the system.Systemd can be interacted with the systemctl command in order to enable, disable, start, stop, restart or check the status of services (those are the systemctl commands).More interestingly, systemd has a fairly accessible interface for configuring and enabling new daemons (or services).Below is an example of a daemon for running a simple Python app.We won’t go in the details but as you can see most of the fields are pretty self explanatory. QMK - If your keyboard supports custom firmware you can use QMK to configure the hardware device itself so the remaps works for any machine you use the keyboard with.You are probably already familiar with the notion of daemons, even if the word seems new.Most computers have a series of processes that are always running in the background rather than waiting for a user to launch them and interact with them.These processes are called daemons and the programs that run as daemons often end with a d to indicate so.For example sshd, the SSH daemon, is the program responsible for listening to incoming SSH requests and checking that the remote user has the necessary credentials to log in.In Linux, systemd (the system daemon) is the most common solution for running and setting up daemon processes.You can run systemctl status to list the current running daemons. Windows - Builtin in Control Panel, AutoHotkey or SharpKeys macOS - karabiner-elements, skhd or BetterTouchTool Having remaps being keyboard or software specific.Some software resources to get started on the topic:

Karabiner Elements Linux Code For Filesystem

rclone - Mount cloud storage services like Dropbox, GDrive, Amazon S3 or Google Cloud Storage and open data locally. sshfs - Open locally remote files/folder through an SSH connection. FUSE lets users run user space code for filesystem calls and then bridges the necessary calls to the kernel interfaces.In practice, this means that users can implement arbitrary functionality for filesystem calls.For example, FUSE can be used so whenever you perform an operation in a virtual filesystem, that operation is forwarded through SSH to a remote machine, performed there, and the output is returned back to you.This way, local programs can see the file as if it was in your computer while in reality it’s in a remote server.Some interesting examples of FUSE filesystems are: FUSEModern software systems are usually composed of smaller building blocks that are composed together.Your operating system supports using different filesystem backends because there is a common language of what operations a filesystem supports.For instance, when you run touch to create a file, touch performs a system call to the kernel to create the file and the kernel performs the appropriate filesystem call to create the given file.A caveat is that UNIX filesystems are traditionally implemented as kernel modules and only the kernel is allowed to perform filesystem calls.FUSE (Filesystem in User Space) allows filesystems to be implemented by a user program.

Instead, having an off-site backup is a recommended practice.Synchronization solutions are not backups. Similarly, an external drive in your home is also a weak backup solution since it could be lost in a fire/robbery/&c. borgbackup - Mount your deduplicated, compressed and encrypted backups for ease of browsing.Any data that you haven’t backed up is data that could be gone at any moment, forever.It’s easy to copy data around, it’s hard to reliably backup data.Here are some good backup basics and the pitfalls of some approaches.First, a copy of the data in the same disk is not a backup, because the disk is the single point of failure for all the data. You can have private, shared and public folders. kbfs - Distributed filesystem with end-to-end encryption. Files are stored encrypted but once the FS is mounted they appear as plaintext in the mountpoint.

They are structured URLs,Often rooted at api.service.com, where the path and query parametersIndicate what data you want to read or what action you want to perform.For the US weather data for example, to get the forecast for aParticular location, you issue GET request (with curl for example) toContains a bunch of other URLs that let you get specific forecasts forThat region. ForExample, the US government has an API that lets you get weatherForecasts, which you could use to easily get a weather forecast in yourMost of these APIs have a similar format. Most services onlineWill have “APIs” that let you programmatically access their data. APIsWe’ve talked a lot in this class about using your computer moreEfficiently to accomplish local tasks, but you will find that many ofThese lessons also extend to the wider internet. They don’t help if data gets deleted, corrupted or encrypted by ransomware.Some core features of good backups solutions are versioning, deduplication and security.Versioning backups ensure that you can access your history of changes and efficiently recover files.Efficient backup solutions use data deduplication to only store incremental changes and reduce the storage overhead.Regarding security, you should ask yourself what someone would need to know/have in order to read your data and, more importantly, to delete all your data and associated backups.Lastly, blindly trusting backups is a terrible idea and you should verify regularly that you can use them to recover data.Backups go beyond local files in your computer.Given the significant growth of web applications, large amounts of your data are only stored in the cloud.For instance, your webmail, social media photos, music playlists in streaming services or online docs are gone if you lose access to the corresponding accounts.Having an offline copy of this information is the way to go, and you can find online tools that people have built to fetch the data and save it.For a more detailed explanation, see 2019’s lecture notes on Backups. For the same reason, disk mirroring solutions like RAID are not backups.
