Learn Emacs?

I think Emacs is something best learned on the side, as a platform - as a programming language, a REPL for that language, a set of libraries, a framework for making GUIs (primarily but not exclusively text-oriented ones), and a package ecosystem. But you should not actually try to use it as your primary text editor, or even learn it as such. If you're like me, you'll spread this journey out in many little tries over many years, and that's fine.

Try the goodies built into Emacs that are not text editing. Try dired. Try eshell. Install Magit and try that. Maybe install and try a preconfigured bundle of config and packages like Spacemacs, not to grow into it but just to see what it's like. Try some Org mode stuff. If you ever use SSH or FTP or whatever, or even just sudo, try TRAMP. Try TRAMP with dired, try TRAMP with eshell, try TRAMP with anything else neat that you've found.

If you're like me, you'll probably walk away after each little thing thinking "yeah okay that's neat, But I don't really get what the big deal is, I could do the same with thing [...]". You'll notice how you could compose a lot of little UNIX programs together to do the same stuff, and you'll like that design more. You'll be annoyed by the startup time vs Neovim, you'll be annoyed by the out-of-the-box deficits relative to VS Code and IntelliJ's stuff and so on. That's fine. The goal is to gradually sample the platform.

To a much lesser extent, only if you're interested in sampling yet another possibility for text-editing interfaces, you might want to try learning its out-of-the-box keybindings for text editing, but... look, personally I think the out-of-the-box experience is at best bad-relative-to-what-you-already-know. I tried it a few times and for me, vi-style modal access to cursor movements and edit operations is a far bigger win than Emacs-style modifier-key access to the same.

You will see mentions of swapping Ctrl and Alt, because that's the layout on the old computers that Emacs' defaults were designed for. You'll also hear people suggest rebinding CapsLock to Ctrl. Honestly I think this is a lower-value detour, presupposing that Emacs as an editor out-of-the-box is worth learning, if only you could just optimize it a little to not give yourself RSI. But if you're going to do that, I suggest also trying Sticky Keys. Maybe it's just me, but I find Emacs' constant modifier key demands far more ergonomic if I can latch or lock modifiers as-needed.

Eventually, once you learn Emacs-as-a-platform enough, you'll start to see that all the little lisp functions and "modes" do a better job of being small composable pieces that do one thing well than UNIX CLI programs. Once you're sufficiently fluent in Emacs-as-a-platform, you'll find it easier to implement the behavior you want in Emacs than in the shell, or in your favorite editor.

And then, only then, will it have been worth it to have learned Emacs. Because then you can build your editor in Emacs. If nothing else, there's a critical mass where it becomes easier to incrementally improve your favorite editor by emulating it in Emacs first. And someone else has probably already done most or all of that work. And then you can keep incrementally improving on it, converging on an editor that's personally optimized to you - a bespoke tailored tool for exactly your mind.

Or that's the idea anyway. I'm not at the end of that journey, I'm just forecasting where it leads. After years of on/off poking at Emacs in various forms, I'm finally fluent enough that I'm incrementally creating something better than my favorite editor (and shell, and window-managing workflow) within Emacs. Not for the sake of doing anything with Emacs, but just because it feels faster and easier within Emacs now than outside of it. I don't know where this lurch ends. Every other lurch into Emacs ended with disappointment, with just enough inefficiency or annoyances that I just gave up on it. This is the first one that felt like it could end with me switching to Emacs as my main thing, but it's still entirely possible that this too will run out of steam.

And that's fine, that's the whole point I'm getting at. Every time I've jumped into Emacs, I made some sort of progress. And then I jump back out and run for a while with a terminal, shell, vi, and various CLIs as my daily tools, because I have to get stuff done after all. Sometimes I did some mix of both - I have memories of using Spacemacs to edit and a separate terminal with a shell for git.

Developing a software product presents a huge challenge for tech leaders and CEOs, especially for those who have decided to go with remote IT engagements. Finding remote talent that would be ready to put in the hours and do the work well is one part of the equation. Then there is management that falls on the shoulders of company leaders. In this article, we look at managing Java remote teams based on our decade-long experience in this field. Decide what Competencies You Are Going To Outsource Tech leaders seek to create remote teams of java software developers to implement a number of solutions. We at Ncube work with companies that need the talent to implement Java EE solutions or build modern applications within Java environments such as Eclipse, NetBeans, IntelliJ IDEA or Android Studio. To develop software based on Java stack one needs to fulfill the following roles: A Software Architect Java Developers QA Engineers UX/UI designer DevOps Product Owner Project Manager Outsourcing part of these responsibilities is a strategic decision. At the same time, it is vital to keep the key elements of business such as ensuring security, marketing, and communication with users at home. Find A Reliable Supplier Of Java Staff Augmentation Considering nearshore opportunities, do some research to find out about the most prominent outsourcing companies in the region. Take a look at their portfolios at GitHub and ask for recent Java cases during a kick-off interview. A bonus in favor of the company would be having at least two success stories with Java technology from your industry. Avoid A Sight Unseen Approach To Hiring Java Solution Experts Interview engineers personally. It’s important to make sure that a candidate meets the requirements for technical skills as well as for communication skills. In fact, soft skills are extremely important for effective working in a distributed environment. At the end of the day, a successful product is a result of team effort. That’s why it is important for every team member to get the ideas across clearly and resonate with the company’s culture and its values. Visit Your Software Development Team On Site After hiring the candidates and setting up a team, the provider is expected to provide IT infrastructure and ensure a comfortable working setting. All administration related expenses are covered by the contract. There is no better way to make sure that these requirements are met other than checking it firsthand. Tech leaders usually meet the new hires before their first working day to walk them through the workflow. Alternatively, a new team member may go to a head office for training and meeting the core team. Make Sure The Feedback Is Flowing Geographical distribution never works in favor of establishing a stable working atmosphere. Without a working feedback system, tech leaders risk being the last to know about disturbances inside the remote team. Keep your remote employees involved through regular surveys and tell them about important things yourself. Essentially, instead of having a project manager fill out the surveys for the whole team, ask every team member to fill out the surveys personally and in detail. Target For Project Manager With Good English Proficiency Hiring a project manager ensures a high level of control over your remote project and deliverables. If a project manager is going to be your single point of contact, he or she needs to be fluent in spoken and written English. It’s fine for the rest of the team to speak with less fluency – Intermediate proficiency will suffice for everyday communication within the team. Professionals with Upper-Intermediate English proficiency and lower are usually deemed as cost-effective in the field of custom software development services. Organize Your Work Using A Set Of Tools Managing a distributed team without knowing what everyone is working on is impossible. To stay in touch and drive results, our teams use: Slack as a virtual

collaborative space with a special channel for Java developers where they can discuss the benefits of the Java programming. Trello for new product features. GitHub for project management. GoToMeeting, Hangouts, and Zoom for video conferencing. Additionally, the employees widely use Google Docs, Sheets, and Slides for file management and data storing. For sharing the non-doc type of files like videos or photos, our choices are DropBox, Google Drive, OneDrive, ZohoDocs. An Afterword From Ncube's Team  Our experience proves that managing remote teams of Java engineers requires the right people, tools, and processes. But what’s more important – a great deal of understanding between a talent vendor, client and project managers. All tasks, requirements, and expectations need to be clearly communicated and documented. Miscommunication may put your project at risk of delaying product deployment. It’s also vital to discuss deadlines and deliverables in advance to see where the pain points might occur and come up with ways to prevent them.
