7 Linux Shell Tips For Increased Productivity Love it or hate it, the command line is here to stay. Sure, there are new options emerging like TermKit but it’s unlikely that the command line will ever really go away. Those who take the time to master it can run productivity circles around their peers, but with the astonishing assortment of CLI tools available, where do you even begin? There are several reasons to make a temporary RAM-based filesystem such as fast read/write times or to guarantee that the files will not persist after reboot. Where /mytemppartion is the location you wish to mount (it must already exist) and 1024m is the desired size of the ramdisk. Linux pros almost certainly know the at command, it lets you set a specific time for a job to be run. If you want to verify that it worked, you can easily list the sceduled jobs with Perhaps you ran a long complicated command, but forgot to preface it with sudo, or maybe you didn’t add some necessary options to the end. to see just such a list.

All commands Customize your internet with an open source search engine A long time ago, the internet was small enough to be indexed by a few people who gathered the names and locations of all websites and listed them each by topic on a page or in a printed book. As the World Wide Web network grew, the "web rings" convention developed, in which sites with a similar theme or topic or sensibility banded together to form a circular path to each member. A visitor to any site in the ring could click a button to proceed to the next or previous site in the ring to discover new sites relevant to their interest. Then for a while, it seemed the internet outgrew itself. Everyone was online, there was a lot of redundancy and spam, and there was no way to find anything. Why choose an open source alternative? Search engines like Google and DuckDuckGo are demonstrably effective. But maybe you prefer not to use Google or DuckDuckGo because of privacy concerns or because you're looking to contribute to an effort to make the internet more independent. Install YaCy

Create web user interfaces with Qt WebAssembly instead of JavaScript When I first heard about WebAssembly and the possibility of creating web user interfaces with Qt, just like I would in ordinary C++, I decided to take a deeper look at the technology. My open source project Pythonic is completely Python-based (PyQt), and I use C++ at work; therefore, this minimal, straightforward WebAssembly tutorial uses Python on the backend and C++ Qt WebAssembly for the frontend. It is aimed at programmers who, like me, are not familiar with web development. git clone cd wasm_qt_example python mysite.py Then visit with your favorite browser. What is WebAssembly? WebAssembly (often shortened to Wasm) is designed primarily to execute portable binary code in web applications to achieve high-execution performance. Toolchain There is a getting started guide on the Qt wiki. To get executable WebAssembly code, simply pass your Qt C++ application through Emscripten. #! The versions on my (Fedora 30) build system are:
Shell startup scripts — flowblok’s blog If you’re a regular shell user, you’ve almost certainly got a .bash_profile or .bashrc script in your home folder, which usually contains various tweaks, such as setting environment variables (adding that directory to $PATH), telling your shell to do clever things (like set -o noclobber) and adding various aliases to commands (like alias please=sudo). (If you’re really organised, you’ll have all your dotfiles in a repository somewhere so that you can keep your settings synchronised across all the machines you work on.) Anyhow, I suspect that few people know when things like .bash_profile and .bashrc actually get executed. When I started, I just followed people’s advice of putting stuff in .bashrc, and then when it didn’t work, into .bash_profile. My solution to this problem is to define some new dotfile folders, one for each shell (.bash/, .zsh/ and .sh/), and one for the shell-independent files (.shell/): “But!” Where to put stuff It all depends on when it needs to be run. Implementation
Create a First-Person Shooter In Godot – Part 1 – Godot Tutorials Introduction Welcome to the tutorial, and get ready to learn some in-demand skills for creating first-person shooter games! Throughout this tutorial, we will work with the 3D aspects of the Godot game engine to enhance your foundations when it comes to action game development. Additionally, we’ll be creating a first-person shooter from scratch, which will show you how to set up the FPS player and camera, enemies, efficient shooting mechanics, health and ammo pickups, and more. Before we begin, it’s important to know that a basic understanding of the Godot engine is required. Project Files For this project, we’ll be using a handful of pre-made assets such as models and textures. You can download the assets for the project here.You can download the complete FPS project here. Improve the security of your multiplayer networks by adding user authentication to your games. Player Authentication with Azure PlayFab Let’s Begin To begin, create a new Godot project. Building Our Environment
Latacora - Stop Using Encrypted Email Email is unsafe and cannot be made safe. The tools we have today to encrypt email are badly flawed. Even if those flaws were fixed, email would remain unsafe. Its problems cannot plausibly be mitigated. Avoid encrypted email. Technologists hate this argument. Most email encryption on the Internet is performative, done as a status signal or show of solidarity. But we have to consider more than the LARP cases. The least interesting problems with encrypted email have to do with PGP. Here’s why. If messages can be sent in plaintext, they will be sent in plaintext. Email is end-to-end unencrypted [1] by default. The clearest example of this problem is something every user of encrypted email has seen: the inevitable unencrypted reply. Even if modern email tools didn’t make it difficult to encrypt messages, the Internet email system would still be designed to expect plaintext. Serious secure messengers foreclose on this possibility. Metadata is as important as content, and email leaks it.
Hackers Were Inside Citrix for Five Months Networking software giant Citrix Systems says malicious hackers were inside its networks for five months between 2018 and 2019, making off with personal and financial data on company employees, contractors, interns, job candidates and their dependents. The disclosure comes almost a year after Citrix acknowledged that digital intruders had broken in by probing its employee accounts for weak passwords. Citrix provides software used by hundreds of thousands of clients worldwide, including most of the Fortune 100 companies. It is perhaps best known for selling virtual private networking (VPN) software that lets users remotely access networks and computers over an encrypted connection. In March 2019, the Federal Bureau of Investigation (FBI) alerted Citrix they had reason to believe cybercriminals had gained access to the company’s internal network. But in a letter sent to affected individuals dated Feb. 10, 2020, Citrix disclosed additional details about the incident.
Offshoring roulette: lessons from outsourcing to India, China and the Philippines I've had this blog post in one form or another of draft for several years now. I hesitated to complete it, in part because at the best of times cultural observations can easily be misinterpreted and also in part because of the role I had in working with many outsourcing vendors across Asia. Whilst the former hesitation has in no way changed, the latter has and I think it's a genuinely interesting topic worth sharing, particularly before my outsourcing memories fade too far. One thing before I begin: these are opinions based on personal observations. Here's what I've learned over many years of outsourcing software projects to India, China and the Philippines. Who am I to talk about offshoring / outsourcing / other cultures? In what is now a former life, I spent a great deal of time sending work overseas. The region covers everything from Pakistan in the west to obviously China, over to Japan and down to my corner of the world in Australia and New Zealand. Why outsource? Why offshore? India
