+# [New Features in Python 3.9 You Should Know About](https://martinheinz.dev/blog/21)
+
+The great feature coming in Python 3.9 is the dictionary shortcut (`|`, as in
+`new_dict = dict1 | dict2`), but there are few more incoming changes.
+
+I talked about the future of Python on [PyCaxias](https://pycaxias.org/) this
+year, and I pointed that Python grew a lot when it entered the web development
+area and now that it is getting into the machine learning area, there will be
+changes coming into the language to support this.
+
+And if you ignore the dict operator, there is _a lot_ of things related to ML.
+
+# [BashTop: Linux resource monitor](https://github.com/aristocratos/bashtop)
+
+When I first receive the link for this, I thought "I bet it looks like any
+other bash script". But no, it has a well designed interface and loops
+interesting as heck.
+
+# [Avoid rewriting a legacy system from scratch, by strangling it](https://understandlegacycode.com/blog/avoid-rewriting-a-legacy-system-from-scratch-by-strangling-it/)
+
+So you don't know how to replace your monolith with another monolith? Here is
+one idea: Create the same API, put a gateway in front of the old system and
+slowly reroute calls to the new service.
+
+# [3 tribes of programming](https://josephg.com/blog/3-tribes/)
+
+It's kinda funny seeing articles that try to pinpoint developers in certain
+categories and end up just splitting everyone.
+
+But this one kinda makes sense, if you're willing to put a random label on
+yourself.
+
+# [12 Signs You’re Working in a Feature Factory](https://cutle.fish/blog/12-signs-youre-working-in-a-feature-factory)
+
+Ah, the good old ways of just pushing buttons and pumping features, with no
+regard to process or anything else.
+
+If you're starting your dev career, at some point you'll work in one of those,
+and recognizing you're in such situation may help your future.
+
+# [Function overloading in Python](https://arpitbhayani.me/blogs/function-overloading)
+
+Ah, the joys of using decorators to add features to the language. In this
+case, using decorators, you can add function overloading to Python, and even
+if it is based on the number of arguments, one could extend this to use the
+type hints for figuring out the function (with some work, I reckon).
+
+# [git-trim: Automatically trims your branches whose tracking remote refs are merged or gone](https://github.com/foriequal0/git-trim)
+
+Keeping your GIT branches clean is good for your health. Removing those stupid
+"fix-this" and "fix-that" after they were merged, but not removing "develop"
+and "master" can be hard work.
+
+This small app helps keeping everything nice and tidy.
+
+# [Always Be Journaling](https://letterstoanewdeveloper.com/2018/12/14/always-be-journaling/)
+
+Today in "Things I Know I Should Be Doing But I Don't": Journaling.
+
+I've seen this "pattern" a few times: Take notes of everything you're doing;
+take notes of problems you solve; keep notes of discussions you had. Those are
+all important and can save your butt in the future.
+
+# [Programming is not a goal.](https://ralsina.me/weblog/posts/programming-is-not-a-goal.html)
+
+I was kinda expecting the "Programming is not a goal, providing value for your
+customers is", but this is way more direct than you can think. It's the clear
+suggestion for those who are starting to focus on solving their own problems
+instead of just coding.
+
+Figuring out how to scrap a website is ok, but what will you do with the data.
+Building a neural network may be used in your CV when you're looking for that
+high-paying job, but you're going to train to fix _what_?
+
+# [What is cache penetration, cache breakdown and cache avalanche?](https://www.pixelstech.net/article/1586522853-What-is-cache-penetration-cache-breakdown-and-cache-avalanche)
+
+I suck at using the "proper" words for some contexts: I used a bunch of
+patterns, but heck if I can remember (or even if I really know) their proper
+names.
+
+This is the same thing: Just some clarification on how to call some
+problems/situations with caches.
+
+# [GNOME has a ‘Secret’ Screen Recorder. Here’s How to Use it!](https://itsfoss.com/gnome-screen-recorder/)
+
+This is a cool thing: You can record your desktop if you're using GNOME. The
+recording will appear as a `webm` in your "Videos" folder.
+
+# [Requirements volatility is the core problem of software engineering](https://stackoverflow.blog/2020/02/20/requirements-volatility-is-the-core-problem-of-software-engineering/)
+
+This should not come as a surprise to anyone who was part any moderately large
+project: things change.
+
+Yes, agile is a way to solve this, but we need to teach developers to "let go"
+of their code. We write code expecting it to live forever, and then the
+requirements change and we hung up on those little grouped words and instead
+of removing and starting with a fresh view, we try to twists and push things
+around till it works, but is barely recognizable.
+
+This part agile doesn't teach us.
+
+# [Using Vim as a password manager](https://invert.svbtle.com/using-vim-as-a-password-manager)
+
+A little stupid trick using VIM: VIM can encrypt files when saving them, so
+you can pick a file, put your passwords, and save it in encrypted form.
+
+# [Pay Up, Or We’ll Make Google Ban Your Ads](https://krebsonsecurity.com/2020/02/pay-up-or-well-make-google-ban-your-ads/)
+
+Not only we have the problem with Google acting the way it wants with its
+products -- and as much as we don't like it, we can't deny its in their own
+right to do so -- now people have to worry about people tricking Google into
+killing your... revenue.
+
+And I think that's one of the basis of the whole problem with privacy and the
+general use of Google products: revenue. Imagine how scared someone could be
+if they decide to pay U$ 5000 just to not kill their revenue.
+
+There has to be a better way.
