Context Going back to the drawing board, I realized that I complicated matters by involving a database. Defining a schema was harder than I thought. I finally settled on the following for displaying inventory. Schemas ¶ I decided I would manually create tables for: color finish location thickness To determine whats in stock, I would pull a report from the inventory management system, then compare it to the colors table. If the repo..

A couple of weeks ago I had the genius idea to rewrite SnailLife in Go. I’ve already looked into doing this once before a couple of years ago, but wasn’t really feeling it and stuck with PHP (mostly for nostaligia reasons). Now though, SnailLife is this bloated PHP app. Most of the core functionality is in. After weeks of battling infrastructure issues, when everything was back up and running again, I took a step back and saw how big the ap..

Context Still having some trouble wrapping my head around sqlalchemy’s orm, putting things into postgres and then querying it. The flow isn’t clear to me yet. Querying ¶ # Automaps the database here. d = sps.Database() # Tables are available in the classes property Inventory = d.base.classes.inventory # Creates a list of sqlalchemy object with all the rows (that's how my query_all method is implemented) data = d.query_all(Inventory) # ..

back to Flying RC Vehicles overview Not being totally happy with the power available with my 2S xyAurora90 I decided to build a 3S Aurora100 in July 2017. The total weight with a 3S 450mAh battery is around 131g. Here are some recordings of the FPV footage. Be aware that these videos are recorded from the received signal on the ground. Not only can you see lots of interference and other HF problems, the loss of quality....

I’ve recently been playing with Kubernetes as way to efficiently host my microservices. It’s great and I’m really enjoying it. One thing that did take me by surprise is that Containers, by default, have credentials mounted which allow them to talk to the cluster API. This is incredibly useful for pulling information about other services, secrets or enabling self-orchestrating/scaling services, however, for the services that don’t need t..

The for loop is one of the most powerful constructions in the C language. It consists of three different parts. The first one is initialization, performed exactly once at the beginning of the loop. The second one is the conditional part, called every time before the loop body. The last one is the increment part, executed on every iteration right after the loop body. Such a loop combines both, linear code and branching in a very customizable..

Context I need to query my database through SQLAlchemy to generate reports and add results to the website. Postgres and SQLAlchemy ¶ Querying in sqlalchemy is taking some time to grok. Most of the examples showed something like this: ''' Tables already created using sqlalchemy models and filled with data. ''' from sqlalchemy import * r = session.query(Table).filter(Table.name=="test").first() This doesn’t really work for me. I ha..

When we first were given access to Splunk we were excited about all the functionality it could provide our team to help us monitor and debug our applications. We created alerts to email us if our applications are logging errors, dashboards to show health or metrics of our services, and field extractions as well as tags to make searching easier. As we created more and more of these Splunk knowledge objects we started to have issues.

Correctly applying architecture patterns to what you’re building, based on the problem being solved isn’t talked about much. Having mostly written scripts in the past, building a module requires a lot more thought upfront . For example, when writing a method, what sorts of inputs do you want to allow for, vs. already having some of those inputs as part of the method. SOLUTION A def clean_report(report, list_of_column_to_drop, dict_of_co..

If you would like to follow along with this post and run the code snippets yourself, you can clone my NLP repository and run the Jupyter notebook . You might not realize it, but you probably use an app everyday that can generate random text that sounds like you: your phon....

Last weekend we held the c-base IoT hack weekend , focused on the Flowhub IoT platform. This was continuation from the workshop we organized at the Bitraf makerspace a week earlier. Same tools and technologies, but slightly different focus areas. c-base is one of the world’s oldest hackerspaces and a crashed space station under Berlin. It is also one of the earliest users of MsgFlo with quite a lot of devices connected via MQTT. ....
