Ask HN: What are some “trivial” achievements you feel satisfied about?

My son is a ventilator patient as of recently, and his ventilator has a usb port on the back that can be used to export the data. According to the manufacturer, the exported files can only be viewed using their proprietary software, which they only distribute to trained medical professionals.

Long story short, with a little digging I found the spec for the file format and was able to write my own parser.

I'm about to finish the second year of my Masters degree in Robotics Engineering, ending on a particularly difficult mathematics heavy course (which was my biggest fear and weakness going into the Master's program).

I had graduated in 2009 with a robotics engineering degree and found not a soul hiring due to the economic collapse. After years of building a software engineering career (which was hard in it's own right) I can't find anyone who will take me on for a robotics oriented software position; most require tons of experience I wasn't granted the option to earn and/or advanced degrees.

...So I bit the bullet two years ago and started my Master's at night after work. It's exhausting but I'm inching closer to an advanced degree and, hopefully, a job working on software directly controlling robots in some way.

Decade+ career switches are hard

Maintaining my goal weight long enough to consider tattoo designs.

Almost 20 years ago, I used the book 'Teach yourself PHP and MySQL in 24 hours' learn PHP so I could build a web application for a VoIP telephony service. I built the whole v1 in that 24 hours, and then went to sleep. I had never used PHP or MySQL before.

Figuring out that one of the services i was maintaining needed http connection pooling for calls to an external service to get within acceptable levels of performance. Spent a fair bit of time and effort to reach the conclusion and should have probably known to use it from the start, with it being a best practice followed in some other services already. Still, the whole process of finding/fixing the bottleneck left me very pleased.

One fine day this last summer, I was standing outside a store finishing my smoke, when a voice behind me said, "Beautiful day". I turned to see the person sitting at a table and said "it sure is".

About a minute later, with no trace of irony, they said "But then every day I wake up is a beautiful day." I'm happy to remember that simple share.

I made my writing app dark mode by default and so many reviews praised the dark background as easier on the eye. even though all the writing apps out there have customizable colors, the small gesture of making dark the default helped a lot of people

When they released the COVID vaccine for under-5s, my wife got my son the first appointment she could find, which was 2.5 months away and after preschool started.

I looked at the appointment site the hospital used, and saw that the way it populated its appointment calendar was to load an endpoint that accepted a date range and just returned a JSON array of appointments. I built a quick bash script and pointed it at Pushover, and a day or two later my phone notified me that there was an appointment available for the very next day.

He ended up getting COVID shortly after starting school and it was ultra-mild, so I'm doubly grateful that a little script might have saved him some suffering as well as freeing us to go out in the world earlier.

I built pure CSS tooltips to show currency conversions on a blog. I was one of those problems that wasn't terribly complex, but the solution called for a nice mix of skills that I was proud to have.

None of it was groundbreaking, but the ease with which I built it gave me a rare feeling of mastery.

I wrote about my approach because of it: https://nicolasbouliane.com/blog/currency-tooltips

This one time, I doubled the speed of our bulk mailing app by reading the template in, setting as a variable, and using that instead of reading the template inside the loop each time. Biggest bang for buck change ever :)
