📅 Jan 18, 2023 — 🧮 378 words — 🏷️ stocks personal

In a previous post about my ROI stock portfolio you could read what my plan was. We’re now 5 months further, and that means we’ve reached the halfway mark of the buying period. So how’s it going? The portfolio As of 10th of January 2023, just before I deposited another €100, the portfolio looked like this: ❌(-3.40%) Microsoft (MSFT) - ❌(-14.07%) ❌(-2.20%) Apple (AAPL) - ❌(-17.41%) ❌(-2.00%) Mastercard (M) - ✔️(+5.

YouTube is my TV

📅 Dec 28, 2022 — 🧮 1846 words — 🏷️ personal youtube

When we bought our house in 2015 we got all the regular communication appliances; TVs and cable subscriptions, landlines, internet, etc. But we soon realized that we prefer to be on our computers more and as such the TV was left unused, most of the time. Recently I realized that I'm really using YouTube as if it was my cable TV. I could also clearly see the type of content that I'm watching, and it made me think that I've actually built my own TV channel.

My ROI stock portfolio experiment

📅 Sep 17, 2022 — 🧮 575 words — 🏷️ stocks personal

After reading a bit about multiple well-known investors mentioning how important Return On Invested Capital is, I decided to generate a small portfolio (actually a pie within Trading212) with some metrics. I used finviz to screen and since they don’t have ROIC, I used Return On Investment (ROI). This is a different metric but is the closest option there is. My screening options were as follows: ROI of 25% or higher Net profit margin of 25% or higher Market cap of 2 billion or higher Positive dividend Average trading volume of 1 million So the important values are the ROI and net profit margins.

svc; an opinionated Go service framework

📅 Jun 17, 2022 — 🧮 1213 words — 🏷️ tech go

I have been writing Go (or Golang) for about 6 years now. In that time I’ve seen quite a few different ways on how to organize a Go project. During my time at MessageBird I got introduced to a nice layered approach. I’ve taken those lessons and applied them to something that feels right for me; github.com/gerbenjacobs/svc svc svc is not an actual framework, but more a convention for creating microservices.

First month at GitHub

📅 Mar 12, 2022 — 🧮 700 words — 🏷️ tech personal

It’s been a month since I joined GitHub in February of 2022. I’m enjoying myself a lot, but I’m also not sure if the reality has set in completely. In 2014 I started my first tech job and remember that I went to a conference and got GitHub stickers, they were awesome and all ended up on my MacBook. Eight years later I now work at that exact company. 🚀

How many points would you give this story?

📅 Jan 5, 2018 — 🧮 804 words — 🏷️ tech

It’s time for a mental exercise. You are going to give story points to a user story, that I actually completed. Then I’m going to tell you what I had to do and which issues I ran into. Background We have a page that lists birthdays for people on the current day, but excluding the current year. In the descending order it then shows their age. This is nice, but if you want to find out whose birthday is on a specific date, you might have to wait a year for it to come around.
