Life, Tech and Unimportant Minutiae

Varana, 137 Projects, Mojave Sonoran Trail, Advanced Outdoor Technologies - 5/10/2022

In upgrading an older service to CoreWCF I ran into some Pinvoke code for 'RawPrinting' (DllImport "winspool.Drv") with an unexpected return value that was causing nothing to print. I suppose this could make an interesting article - identify why this code worked under .NET Framework 4.61 and not .NET Core 6+, show the subtle code changes between .NET versions and maybe offer a clever PowerShell one-liner that would fix this problem in all of your code... I did none of that - I quickly made an honest assessment that my DllImports were copy and pasted, that I have only the most basic knowledge of how Pinvoke/IntPtr/Dllimports 'really' work and that exploring the details of various interop printing structures was unlikely to really be all-things-considered worth the time. In the end vague memories and web searches led me to Vanara: A set of .NET libraries for Windows implementing PInvoke calls to many native Windows APIs with supporting wrappers. Several minutes of light refactoring later printing was working again! (Oh and yes - this was all in service of pushing ZPL to the wonder, and occasional terror, that is our Zebra tag printers...)

At work over the past two decades we basically maxed out at 4 in-house developers - always with some part time positions - but right now I'm the sole in-house Dev/IT person. A big challenge with over 2 decades worth of in-house development is figuring out how to move things forward. Recently I took some inspiration from larger dev organizations and made the last commit in a branch that combines 137 projects under one solution. You can easily find information online about monorepo and monolith (usually vs micro-service) setups -> in the big picture our codebase is small and I am currently a team of 1, a much much much simpler situation than anything you will read about - but since our code base has traditionally been divided into silos I am hoping with this change to:

We have plenty of code not in the current 137 project solution, legacy problems to solve and business challenges ahead - it isn't that I think this is a magic solution to our, or anyone's, problems - but I'm writing about it because I'm excited to find a way to improve and move forward even if it isn't a silver-bullet-everything solution to all software issues.

Mojave Sonoran Trail: A 625 Mile Thru-Hiking Route Introduction & Guide - always interesting to see something new and I have to say that even with 2 decades in the Southwest this route touches on MANY areas that I never considered exploring - worth checking out although I'd watch the first few YouTube videos before getting too excited as some of the scrambling looked a little intimidating to me!

Advanced Outdoor Technologies - I do love a good front-pack setup and this new-to-me company is making some interesting gear! I haven't ever seen these bags in person but at a glance they to be designed with a smart 'depth' - having tried a decent number of front packs this is key if you want to be able to see your feet (and you really do want to see you feet)... I currently use a Pajaro GRANDE Field Bag as a front pack, mainly for my camera.
