+
+Summer is here!
+
+Even without restrictions or quarantine is has been a weird month. Cases here are going up and down,
+I don't want to go back to the gym (and I think I won't until next year), some restaurants and cafe
+have closed permanently and the ones that are still standing are usually full (which is good). We're
+just trying to go back to normal, step by step, and having some friends stay at home a few days 
+helped a lot.
+

+
+<!-- readmore -->
+
+This month I have focused on getting more organized. As I said [last month](/blog/2020/06/02/june/) 
+I badly needed it.
+
+I have managed to move almost everything into my [notion.so](https://notion.so/) workspace. 
+I had some boards and notes here and there but Notion is so powerful and comfortable to use that I 
+just went all in. There's some cleanup to do, but my main points of interes are already there. I have
+a board with my personal tasks and some metadata about them, and secondary boards for my hobbies 
+(Games, Books, TVShows, etc), Blog related posts, ... I may go into more detail in the future.

+    </a>
+  </div>
+</div>
+
+Related to this I'm also starting to cleanup every last drawer at home. I got a bit tired of not
+knowing how much stuff I have so I'm making a full inventory of _everything_. It all started 
+reviewing how many of my clothers would still fit me after quarantine, and it snapped on me. I
+don't know how much I own, and I think it happens to all of us at different levels.
+
+With tech this is gonna be very difficult, I have managed to stash a lot (**a lot**) of cables
+during the years. Just imagine how many HDMI and USB cables the average tech guy can get a hold
+of... Arduinos, Raspberries... etc. 
+
+This will take time, but I'm very happy with the progress I already had and all the things I've
+already donated or sold.
+
+## Projects
+
+- My **local infra** is mostly done at this point. I just need to secure everything a bit more
+  but has been working fine (with some hiccups) for the past months. I may need to check some
+  networking alternatives and move all SSL negotiation to the main node (avoiding re-encrypting 
+  traffic on a non-controlled node).
+
+- **Butterrobot** got some love this month. I'm _slowly_ setting up an automated CI/CD system to
+  deploy the application in my local infra, but I need to setup some other details as well. Source
+  code is already on Github though repository is private while I made last minute changes. I'm
+  hoping to release it this month.
+
+- I'm also cleaning up my **Home Assistant** node. What that really means that I'm re-deploying a
+  new instance on a more powerful Raspberry Pi. I have been playing with this software for years
+  and my current pi is a bit underpowered and messy, so the plan is start from scratch trying to
+  make the connected devices local trying to avoid third-party clouds as much as possible and
+  document everything in some blog posts. Let see how that goes.
+
+## TV Shows
+
+I watched something!
+
+- **M.A.R.V.E.L.s Agents of Shield**
+
+  Some chapters of the last season. This may be the worst season so far...? (At least the few I saw)
+
+- **The 100**
+
+  Up to date with this one, without much focus because some interdimensional time thingy is not very
+  appealing to me, just want to know how it all ends. If it doesn't end this season, I'm done with it.
+
+- **Sword Art Online (Aincrad saga only)**
+
+  Rewatched this one (a friend's fault) as series to have while cooking and doing chores. A bit complex
+  to read subtitles the same time you do other things, but since this is a re-watch... Now looking for
+  some other series with the same "protagonist sent to fantasy world" genre.
+
+## Games
+
+- [**Final Fantasy VII: Remake**](https://store.playstation.com/es-es/product/EP0082-CUSA07187_00-FFVIIREMAKE00000)
+
+  I have gone through a bit more of the story, trying to enjoy the story till the end. And wait
+  another five years for the next chapter...?
+
+- [**Reventure**](https://store.steampowered.com/app/900270/Reventure/)
+   
+  Quick play sessions are quick. Oh my god this game has soooo many endings...
+
+- [**Carrion**](https://www.xbox.com/en-US/games/carrion)
+
+  This has been on my radar for quite some time. It's a shame is so short! Finished in a few hours, but that didn't mean
+  is not great, because it is. Being the monster trapped wanted to go out instead of the _"Hero"_ killing monsters is
+  a really appreciated change of perspective. The mechanics were amazing and the graphics gorgeous, it was very fun while it
+  lasted. 
+
+- [**Rick and Morty: Virtual Rick-ality**](https://store.steampowered.com/app/469610/Rick_and_Morty_Virtual_Rickality/)
+
+  I got time to play some VR, and I had this in the backlog for quite some time. I love Rick and Morty and this was
+  a short and fun puzzle adventure, just what I expected. I could get on with the optional stuff but I just have too much
+  on backlog!
+
+## Articles
+
+I forgot to take note of the interesting ones this month. :sweat_smile:
