For the past several years, I’ve set goals for the coming new year while also reflecting and reviewing on how I did during the year. More often than not, I fall short of my ambition in so far as I had a cross-off-worthy outcome; how dreadful, to deny that sweet satisfaction. At the same time, however, I often have made some progress towards a goal but, for whatever reason: uncontrollable factors, escalating priorities, laziness, life events, et cetera, the progress stalled or stopped. https://blog.robertsimoes.org/learnings/2023/ Sat, 23 Dec 2023 09:56:24 -0500 https://blog.robertsimoes.org/learnings/2023/ What loves you never leaves you - love it back.

The website focuses on building project ideas into small businesses that generate a modest amount of revenue. For example, a one-item store or the silicon valley domains. For the preceding several years contemporary business culture (1) has focused, in excess, on the concept of innovation driven ventures (IDVs) or “start-ups” (a la Bill Aulet’s definition in Disciplined Entrepreneurship). The idea of an IDV or “start-up” is juxtaposed with the “less interesting”, but more familiar, idea of a small to medium-sized business (SMB): art supplies stores, family restaurants, grammar schools, et cetera. https://blog.robertsimoes.org/posts/disentangle-schema-changes-and-business-logic-changesets/ Wed, 26 Apr 2023 10:43:26 -0400 https://blog.robertsimoes.org/posts/disentangle-schema-changes-and-business-logic-changesets/ Rails makes writing migrations and performing them on our database so easy! bundle exec rails g migration CreateAllTheThings Why, with only less than 100 keystrokes your off to the races modifying your database.

At the time, he told me to delete the lines instead of commenting them out; citing that “dead code” (e. https://blog.robertsimoes.org/posts/four-wings-of-software-engineers/ Sun, 05 Feb 2023 14:30:06 -0500 https://blog.robertsimoes.org/posts/four-wings-of-software-engineers/ Amateur field notes in the psychology of software engineers Having been asked a sufficient number of times, “what my ideal role is” or “what type of engineer I want to be” - it suddenly dawned on me, in boredom, that there are approximately four behavioural axis with which one view a given software engineer. I use the term “wings”, stolen from the personality typing methodology in the Enneagram, to imply that all four functions are possessed by a given engineer; but, in similar manner to the Enneagram, an individual tends to “lean” more heavily on a set of wings compared to others. https://blog.robertsimoes.org/posts/tool-self-written-contract/ Thu, 05 Jan 2023 07:16:05 -0500 https://blog.robertsimoes.org/posts/tool-self-written-contract/ The self written contract is a tool taken from Julia Cameron’s The Artist Way. I do not know why it works but it seems to be able to solidify and ensure commitment to a given path or action. The tool works as follows: Suppose you have a decision, action or behaviour that you wish to change. For some reason or other, you have a change or action to take that you find it nearly impossible to commit to; you allow the idea to stir inside the skull until it drives you insane. https://blog.robertsimoes.org/learnings/2022/ Sat, 10 Dec 2022 16:49:46 -0500 https://blog.robertsimoes.org/learnings/2022/ The following is an excerpt from my 2022 letter 2.

Create a content index at the start of the book with references to the page and point of interest. This makes retrieval of details trivial because the associated notes live in the same location as the information [1]. If you already take notes in the margins of books consider adding this technique too to further index your margin comments and make retrieval easier. https://blog.robertsimoes.org/posts/tool-5-4-3-2-1-method/ Sat, 08 Oct 2022 16:02:30 -0400 https://blog.robertsimoes.org/posts/tool-5-4-3-2-1-method/ The 5, 4, 3, 2, 1 method is a goal prioritization method found in the book The Bullet Journal Method.

You can use ERB for your own custom templates as well. Usage Create a template file for use, for example, __template.erb.txt. You will need to use the ERB syntax to enable the template to render data properly. # __template.erb.txt First Name:<%= first_name %> Last Name:<%= last_name %> PhoneNumber:<%= phone %> Next you need to create the class containing the attributes (or methods) specified in the ERB file that will be used as the data source to render. https://blog.robertsimoes.org/posts/how-to-setup-hardhat-network-default-accounts/ Mon, 12 Sep 2022 15:05:26 -0400 https://blog.robertsimoes.org/posts/how-to-setup-hardhat-network-default-accounts/ NOTE: This tutorial is for hardhat version ^2.4.1 By default, Hardhat has a local network called the hardhat network with chainId 31337 that runs on localhost:8545.
