    1. Programming Challenge: Convert between units

      Hi everyone! It's been a long time since last programming challenge list, and here's a nice one I've encountered.

      If you search for something like 7km to AU, you'll get your answer. But how is it done? I don't think they hardcoded all 23 units of distance and every conversion factor between them.

      If you were programming a conversion system - how would you do it?

      First of all, you have input in format that you can specify, for example something like this:

      meter kilometer 1000
      mile kilometer 1.609344
      second minute 60
      ...
      

      Then you should be able answer queries. For example 7 mile meter should convert 7 miles to meters, which is 11265.41.

      Can you design an algorithm that will convert any unit into any other unit?

      Edit: Some conversion rates I extracted from wikipedia:

    2. Typesetting Markdown Blog: What Next?

      Some of you have read the Typesetting Markdown blog series (https://dave.autonoma.ca/blog/). The plan was to finish the last two parts with Annotated Text (basically markup for Markdown) and Figure Drawing (MetaPost); however, people have asked for a post on Markdown to EPUB, others have asked for high-quality PDF theme templates using ConTeXt, and some have requested rendering Markdown into HTML.

      Within the realm of Markdown, digital documentation, typesetting with ConTeXt, R, externalized interpolated strings, and bash scripting, what would interest you for the next post in the series?

      (Please flip through the blog series to see the topics that have been covered.)

    3. I'm trying to get a programming job without a degree. Got any tips?

      Hey ~, I'm trying to get a programming job. I don't have a degree (I may go to college, but if I do it'll be in a few months), and little work experience. Do you have any tips that could help me have a successful job search?

      Here's my resume (somewhat anonymized). I tried to focus on experience I've gained from creating open-source projects to show the skills that I have. I've made sure that all the projects listed have demos, screenshots, usage instructions, etc. Any advice on how I could improve it would be appreciated.

      Thanks!

    4. Which language would you pick to completely rewrite BSD, Linux, etc.?

      It'd my understanding that C has stuck around in the UNIX world for so long, nearly half a century, mostly due to the inertia of legacy code. If you could snap your fingers and magically port/fork...

      It'd my understanding that C has stuck around in the UNIX world for so long, nearly half a century, mostly due to the inertia of legacy code.

      If you could snap your fingers and magically port/fork the entire stack of open source codebases to the language of your choice, which would you pick and why?

    5. Topic Requests: What subject would you like to see covered in more depth?

      For those who haven't seen my essay-length posts in the past, I occasionally like to delve into explaining different programming concepts, particularly with regards to making your code easier to manage. Sometimes this has to do with how you structure you code and projects, and at others it has to do with how you think about the problems you're solving. I've been in the mood to write up on yet another programming subject, but nothing in particular has stood out to me lately during the course of my work.

      With that in mind, I figured I would take a different approach and see if anyone here had some specific requests for content they would like to see. Requests from all levels of experience are welcome!

      (And for those who are itching to do a write-up on any of the requests that appear here, feel free to call dibs!)


      Edit

      For those who want to take a dive into my previous submissions, you can now find them in the new wiki entry created by @cfabbro or directly via the programming.code_quality_tips tag here.

      https://gitlab.com/smoores/pliant

      I’ve been a software developer for about three years, and I’ve always been enticed by and passionate about the open source scene. I have an assortment of projects variously available on GitHub and GitLab, but this is the first time I’ve ever created an open source project intended to be used by others.

      Pliant is a barebones starter kit for anyone wanting to self host their own blog. It came out of my own efforts to start a blog, and it’s what currently powers https://tfhe.shanemoore.me.

      I’d love to hear you’re feedback, or just discuss open source, blogging, web technologies, or whatever else comes up.
