tmux is a terminal multiplexer: it enables a number of terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.
tmux uses a client-server model. The server holds multiple sessions and each window is a independent entity which may be freely linked to multiple sessions, moved between sessions and otherwise manipulated. Each session may be attached to (display and accept keyboard input from) multiple clients.
tmux is intended to be a modern, BSD-licensed alternative to programs such as GNU screen. Major features include:
A powerful, consistent, well-documented and easily scriptable command interface. A window may be split horizontally and vertically into panes. Panes can be freely moved and resized, or arranged into one of four preset layouts. Support for UTF-8 and 256-colour terminals. Copy and paste with multiple buffers. Interactive menus to select windows, sessions or clients. Change the current window by searching for text in the target. Terminal locking, manually or after a timeout. A clean, easily extended, BSD-licensed codebase, under active development.
htop is an interactive process viewer for Linux. It is a text-mode application (for console or X terminals) and requires ncurses. htop is an interactive top replacement that runs in the terminal.

Comparison between htop and top
- In 'htop' you can scroll the list vertically and horizontally to see all processes and complete command lines.
- In 'top' you are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident).
- 'htop' starts faster ('top' seems to collect data for a while before displaying anything).
- In 'htop' you don't need to type the process number to kill a process, in 'top' you do.
- In 'htop' you don't need to type the process number or the priority value to renice a process, in 'top' you do.
- 'htop' supports mouse operation, 'top' doesn't
- 'top' is older, hence, more used and tested.

Telegram is a messaging app created by former VK creators with a focus on speed and security. It’s superfast, simple and free. It is like SMS, but more powerful.
You can send messages, photos and videos to people who are in your phone contacts (and have Telegram). You can also create groups for up to 200000 people or channels for unlimited subscribers.
Your chats are not encrypted by default, which enables other people to see what you are writing. You can enable a "Secret Chat" to enable end-to-end encryption.
Telegram offers a Premium plan too: by subscribing to Telegram Premium, users unlock doubled limits, 4 GB file uploads, faster downloads, exclusive stickers and reactions, improved chat management – and a whole lot more. At the same time, all existing features that users have come to expect and rely on for nearly a decade remain free. Moreover, non-premium users will be able to enjoy some of Premium's benefits: for example, download the extra-large documents and view stickers sent by premium users, as well as tap to increase counters on premium reactions that were already added to a message. There are different prices for the Premium subscription based on your country, also if you buy it via the @premiumbot you don't have to pay the app store fees.
Telegram's security model has received notable criticism by cryptography experts. They criticized the general security model of permanently storing all contacts, messages and media together with their decryption keys on its servers by default and by not enabling end-to-end encryption for messages by default.
Telegram's client-side code is open-source software, whereas its server-side code is closed-source and proprietary. The service also provides public APIs with which developers can access the same functionality as Telegram's official apps to build their own messaging applications.
Telegram also provides a bot API for programmers to create different kinds of Telegram bots. Bots are simply Telegram accounts operated by software – not people – and they'll often have AI features. They can do anything – teach, play, search, broadcast, remind, connect, integrate with other services, or even pass commands to the Internet of Things.

Bitwarden is the easiest and safest way to store all of your logins and passwords while conveniently keeping them synced between all of your devices.
Password theft is a serious problem. The websites and apps that you use are under attack every day. Security breaches occur and your passwords are stolen. When you reuse the same passwords across apps and websites hackers can easily access your email, bank, and other important accounts.
Security experts recommend that you use a different, randomly generated password for every account that you create. But how do you manage all those passwords? Bitwarden makes it easy for you to create, store, and access your passwords.
Bitwarden stores all of your logins in an encrypted vault that syncs across all of your devices. Since it's fully encrypted before it ever leaves your device, only you have access to your data. Not even the team at Bitwarden can read your data, even if we wanted to. Your data is sealed with AES-256 bit encryption, salted hashing, and PBKDF2 SHA-256.
Bitwarden is 100% open source software. The source code for Bitwarden is hosted on GitHub and everyone is free to review, audit, and contribute to the Bitwarden codebase.
