A boring solution for a boring problem - Working with PDFs. I've been making a browser-based PDF editor that runs on-device via Webassembly / PDFium. Many of the hard parts were do…

Every time I have to open Acrobat it makes me want to puke, and Bluebeam is quite expensive, so I'm working on a full-featured PDF editor you can run in the browser. https://DraftP…

Many structural engineering graduate students still get exposed to TCL as its the input language of the OpenSees framework for structural and earthquake engineering. https://opense…

I’ve been using these and vercels v0 to piece together a next.js app, and it works pretty good, for someone with no real ui design experience.

I can believe it, after all, I ingest most of my water in a mixture with roasted ground beans from the rainforest.

This exists and it’s not even that hard or costly when you consider the purchase price of a house. I had a home energy evaluation completed when I bought my house for about $400. A…

This isn’t correct. You probably saw a concrete residential building and a steel office building by chance. It does not follow that every single office building is built this way. …

Excel is transformational. If you're reading this indoors, there's a good chance that significant portions of the building around you were engineered using excel.

A hammock hung in a shady grove of trees. Perfect for lazy Sunday afternoons. A bunch of tplink smart light switches for the well used lights around the house. Deep satisfaction ev…

If you follow the inlet back to the ocean a short ways, you reach Gingolx (Kincolith) [1] which has [1] https://en.wikipedia.org/wiki/Ging%CC%B1olx

I suppose it was built without the back pressure (ie doesn’t rely on back pressure for stability) and the change in pressure over time is quite gradual (this drawdown has been occu…

Nice. What was the upfront cost and expected payoff time when compared to grid only?

A bit of UBC apple trivia which I thought was neat is that the trees in front of UBC Triumf facility are descendants of perhaps the most famous apple tree of all, the one Sir Isaac…

its every bored daydreaming passenger's dream come true!

Well, I guess I should rethink my constant urge to leave structural engineering and become a software developer. “The grass is greener…” fallacy seems to be prevalent in most peopl…

I made this website for various little calculations and references I need to look up all the time for the day job. Its useful for me, and kind of relaxing to work on, so I'll keep …

Interesting read, who hasn't dreamt of doing something like this (perhaps at different scales). I've started saving for a parcel of land in the Kootenays to build a.. ahem... much …

fyi email isn't shown, you have to add it to your 'about' to appear

This was really well written and researched, and I say that as a structural engineer who predominantly designs tall buildings. I’m not at all libertarian with respect to things lik…

Slightly different because the Burj is empty by design, while the other examples were empty due to market forces

Nope, not interested in paying for photo storage, although I do use it currently because it’s free and convenient. Would rather just operate in Web 1.0 and download to my computer …

[clarification: I mixed up my unit conversion. A 3/4" A325 bolt resists ~25kip shear or 31kip tension. One of the joys of working in an industry that primarily uses customary units…

Rigidity is good for some things and bad for others. In seismic design, inertial forces tend to decrease as structures become more flexible (Good!). But the consequence is that thi…

A scissor stair can fit 2 stairways very compactly, looks like this is used on 432 park ave, for instance. https://images.app.goo.gl/kz1826Y8xydc9G9L8
