For the most part, Go developers are pretty good about using constants for global configuration, rather than global variables.  A problem arises however when we want a global constant slice or map. The go compiler doesn't allow these more complex types to be set as constant. Many developers, upon making this realization, decide to then use a dangerous global variable. In this article we will explore a better option.

Let's say I have a spreadsheet on Google Sheets which is not public and I want to be able to read/modify programmatically through some batch process running on my local machine or some server. This is something I had to do recently with a Node.js application and I found the authentication part a bit tricky to understand. So I thought of sharing my solution and I hope it helps someone in need. There might be better ways of doing this but I am sharing what worked best for me.

Since the early days of Unix, the shell has been part of the user's interface with the operating system. The first Unix shell (the Thompson shell) had very limited features, mainly I/O redirection and command pipelines. Later shells expanded on that early shell and added more and more capabilities, which gave us powerful features that include word expansion, history substitution, loops and conditional expressions, among many others.

I know, it’s been a while since the last time I published something newbies-friendly on my blog. The main reason is that most of my readers are either experienced devs or from C background having modest C++ encounter. But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.

There are so many great use cases for versioning. Handling code deployments, document edits, and database snapshots are just a few immediate uses that come to mind. Normally, a versioning system is another segment within a database, but it can be so much more when you think of it through the lens of immutable data and DHT (distributed hash tables) technology. So, today, we’re going to build a stream of consciousness note-taking app with version history. This will be different than other notes apps as it will have just ONE note that the user can edit over time, removing information or adding information. But we’ll include versions so they can grab their history. We’ll do all that by using Blockstack and IPFS.

RSS feeds are a largely underestimated feature of the web nowadays — at least outside the circles of geeks. Not only they are much more omnipresent than many think (every single respectable news website provides at least one feed); not only they empower users with the possibility of creating their own news feeds and boards through aggregators, without relying on the mercy of a cloud-run algorithm; but their structured nature (under the hood an RSS feed is just a structured XML) offers the possibility to build automation pipelines that deliver the content we want wherever we want, whenever we want, in whichever format we want. IFTTT is a popular option to build custom logic on RSS feeds. It makes it very intuitive to build relatively complex rules such as “send me a weekly digest with The Economist articles published in the latest issue”, or “send a Telegram message with the digest from NYT every day at 6am”, or “send a notification to my mobile whenever XKCD publishes new comics”.
