DigitalOcean droplet provisioning with Pulumi

The snowflake VM I run my experiments on has a serious flaw. I can't remember what I have installed there. It is embarrassing as some essential services to me run there.

As an enterprisey developer, my attention draws naturally towards IaC solutions for this particular memory issue. The code of the experimentations is in git, so why not the infra. Some would say it is a major overkill since we are talking literally about one domain running on the puniest DigitalOcean droplet. I say I have a weekend to spare on silly stuff.

The easiest choice is to write some Terraform. Yet come to think of it, is it still an obvious pick in 2022? I've never written anything too complex with it but having heard so much backlash against Terraform language, is it time for something new? The answer turns out to be a yes.

The IaC solution for me in 2022 is Pulumi. It has a catchy name, a base for a good dad joke for a Finn. Besides that, Pulumi has some attractive qualities to it.

It is declarative
I can write the code in TS or Go
I can store the state for free in their service

The actual Pulumi code is super simple in my case. I struggled somewhat with how to pass configs stored in Pulumi around. Here is a snippet of how to do that for a user data script (yes, this is old-school stuff)

I'm not a passionate developer

A family friend of mine is an airlane pilot. A dream job for most, right? As a child, I certainly thought so. Now that I can have grown-up talks with him, I have discovered a more accurate description of his profession. He says that the truth about the job is that it is boring. To me, that is not that surprising. Airplanes are cool and all, but when you are in the middle of the Atlantic sitting next to the colleague you have been talking to past five years, how stimulating can that be? When he says the job is boring, it is not a bad kind of boring. It is a very specific boring. The "boring" you would want as a passenger. Uneventful. Yet, he loves his job. According to him, an experienced pilot is most pleased when each and every tiny thing in the flight plan - goes according to plan. Passengers in the cabin of an expert pilot sit in the comfort of not even noticing who is flying. As someone employed in a field where being boring is not exactly in high demand, this sounds pro

Extracting object properties from an IFC file with IfcOpenShell

Besides the object geometry information, IFC files may contain properties for the IFC objects. The properties can be, for example, some predefined dimension information such as an object volume or a choice of material. Some of the properties are predefined in the IFC standards, but custom ones can be added. IFC files can be massive and resource-intensive to process, so in some cases, it helps to separate the object properties from the geometry data. IfcOpenShell is a toolset for processing IFC files. It is written mostly in C++ but also provides a Python interface. To read an IFC file >>> ifc_file = ifcopenshell.open("model.ifc") Fetch all objects of type IfcSlab >>> slab = ifc_file.by_type("IfcSlab")[1] Get the list of properties >>> slab.IsDefinedBy (#145075=IfcRelDefinesByType('2_fok0__fAcBZmMlQcYwie',#1,$,$,(#27,#59),#145074), #145140=IfcRelDefinesByProperties('3U2LyORgXC2f_hWf6I16C1',#1,$,$,(#27,#59),#145141), #145142

Hubristic developer

Almost half of any Finnish generation goes through a shared experience: the conscript army. An integral part of that experience is learning military slang, a set way people in the army talk. The stories told with said jargon often spread outside of the barracks. It is not uncommon to hear strangers bonding together over beers reminiscing and feeling nostalgic about freezing cold nights spent in tents. There is a similar phenomenon detectable among us coders. To be part of the coder tribe, there is at least one type of story that one must master. That is - of course - ranting about legacy codebases. "Can you believe how much of a mess the previous coders left? Hear, hear!" There is no better way to onboard a new team member than to blame some previous B-team for all the murky parts of the system at hand. This can be seen as harmless, a subject for a good meme . Rarely do we hold real grudges against "the legacy folk" and can be the best of friends in a social gather
