This is an old school trick that you use when you don't have a robust test suite and / or a CI environment. When you run Rails in development mode it is VERY, VERY forgiving of little details like syntax errors – the type of thing that grind your web server to a hard stop. The trick is to use RAILS_ENV=production in development mode and that causes syntax errors to get caught: RAILS_ENV=production bundle exec rails s -p3169 Here....

My last post omitted the real reason I hadn't swapped to OnlyOffice was that I was too lazy to look further into apparmor. Allowing dash to inherit the php permissions with /bin/dash ix, is one solution but for other reasons, I wanted to write a more contained profile to spawn dash within. Searching the internet & reading my favourite apparmor docs didn't enlighten.

Last Wednesday, Penn extended Spring Break by a week and moved classes online for a semester in response to the threat of COVID-19. The same day, the WHO declared the virus’s global spread officially a pandemic. In the days since, I’ve packed up my dorm room and moved home. I’ve tried to see how I could use this time effectively — tackling projects I wouldn’t necessarily have time for in a busy college schedule, and learning new skills. H....

Zip code data is always problematic due to the leading zeros. The smarter_csv gem in Rails defaults to automatically handling numbers as numerics, not strings, which means that you lose 00408 to just 408. Here's an example of a work around using a rake task to load data: # bundle exec rake data:import_geography --trace task :import_geography => :environment do path = File . join ( Rails . root , 'lib/tasks/..

The first few paragraphs cover what I was looking for and what I considered. Then the review. Why the Surface Book 2 I used a Macbook throughout my professional career until I had the choice a few years ago when I started my current job. Here, I ran Gentoo, then FreeBSD, then Arch, and now Windows 10 on the Dell XPS 15. I enjoy Windows and I think Microsoft is doing a better job on hardware and software these days. At least, compared to ....

While I’m finishing the last touches on my graduation thesis (posts about that will follow soon) I wanted to take my mind off a little bit with some hobby. I have always been fascinated by presenting data in a clear and automated way and wanted to experiment a bit with that. As a subject for this I chose the big crisis of this moment: the corona virus or Covid-19. This posts serves as quick write up documenting various scripts and tools tha..

I think back to my time in college, and I learned some valuable things. I also learned some incredibly worthless things (i.e. don’t flip a car upside down and then backover… it’ll break the axle so you can’t roll it). Even in classes… the basic approach to a supply/demand curve to maximize profit is cute when done in a classroom vs. the complexities of how things actually work… I mean I get the idea behind it, but what you learn is so far b....

Ordinarily, you will not want to cache POST requests. RFC 2616 does allow, though, for the idea that responses to a POST may sometimes be cacheable . Generally speaking, whether you consider POST cacheable will depend on what happens on the application back-end in response to that POST - if something is changed as a result then you'll almost certainly not want to cache, whereas if POST is being used to submit (say) search criteria, then ....

TL;DR; simply run docker pull akhenakh/kvtiles:planet-9-latest for a self hosted free performant world map (more maps and levels available see kvtiles docker tags).

KVTiles kvtiles is a map tiles self hosted solution written in Go, it’s using Mapbox vector format but rather than using the regular sqlite3 database it’s ..

Table of Contents The Problem The Solution Within Debezium , the project I’m working on at Red Hat, we recently encountered an "interesting" situation where we had to resolve a rather difficult merge conflict. As others where interested in how we addressed the issue, and also for our own future reference, I’m going to give a quick run down of the problem we encountered and how we solved it.
