IDEs and other Tools


When we start at a new company, the environment is as it is - we learn how to work within it, become experts in it if we aren't already, and develop ways that help us thrive in the environment.

As the years go on, the environment changes - the build systems need overhauling, or the IDEs or software versions need and are upgraded, or a new tool or process is introduced, or the organization is re-worked -- which might impact any number of things from how and who you interact with, to your retirement savings approach, to your long term professional motivations.

Each pivot, or adjustment, or "ask" from the company involves needing to - likely - do a messy transition, from what you used to know, to what TheNewThing is. Holding space in your memory for what you're transitioning from, while carving out space for what's being adjusted. Sometimes it can feel like changing the oil in a car while still driving. It can be tough - and as an aside, its often interesting when we don't celebrate or recognize the work involved in such transitions.

And over the years, doing this again, and again, and again, can be exhausting, demoralizing and make us weary of the next NewThing or even seeking out a NewThing.

But what I find particularly interesting is when you pick up and leave and change to a new company, you free up much of the mental space that's been carved out. You're genuinely open to a new way to do things, to whatever the new environment is like, and accepting of it, where its at.

So the question is: are there better ways of accepting a pivot or an adjustment or "ask". How can one repeatedly and actively accept a team or company precisely where its at - even during a transition - rather than feeling bogged down in trying to re-organize yet another approach. How do we stay open and excited about all these pivots, especially through the years?

Interesting Vlog / Podcast

Interesting interview by Lex Fridman with John Carmack - one of the programmers behind Doom, Quake, etc, currently working at Meta on the metaverse and AI.

Some of the interesting takeaways so far:

Don't Quit

Shortly after undergrad, I took on an absolute dream job - computer graphics development surrounded by other smart-cookie graphics developers working on the state of the art in 3d modelling. And I worked my ass off trying to contribute as much as I could as well as I could, fixing bugs, adding small features, supporting various platforms and customers across vast time zones. I learned so, so much, and contributed decently well, especially given I was told - as a junior - not bother the non-junior engineers. But, c'est la vie, it was not enough for the company and I was put on a Performance Improvement Plan (PIP). Unaware what exactly that meant, despite best efforts to survive, it wasn't enough.

My confidence was shattered.

Because text is fun

Text editors look easy - type some characters in a box. Done. But when you drill into it, implementing text editing well is highly involved. This showcases a few examples of why its hard, but honestly it barely scratches the surface. This is why we build things well, build them once, and re-use to high heaven.

GitHub vs. Microsoft's TFS

Word to the wise: Github is not the golden unicorn others might think it is when comparing it to Microsoft Teams.

Sure, there are some great things about it (comparing between branches/changesets for a given pull request), but its teh sux for leaving and responding to code review comments (Did you really need to disable a comment chain when I've updated one variable in the adjacent block?). I also miss the in-editor reviewing, so its easier to test out changes locally (vs. online on github). I'm just saying. Not a golden unicorn...

Fun 3D File Format Functionality

So apparently Pixar created Universal Scene Description file format, which is converging on being pretty well used across a variety of 3D products these days. Its lacking in some extraneous functionality (animation - couldn't figure out a common schema; and seemingly a variety of projection approaches/camera descriptions amongst others), but is a solid foundation for converging on file formats. Something the industry has struggled with FOREVER.

Anyhoo, some relevant links:

  • Overview
  • Geometry - API documentation. Discussion includes supported primitives (eg. for fast collision detection/common representations), as well as mesh, nurbs, etc. and conventions adopted (eg. right hand rule, RH coordinate system for winding)
  • Rendering Overview - API documentation. Discussion includes camera setup and pixel ratios

Fun Specs for WFH

Had a conversation earlier today about how I've got my system setup for working from home. So:

  • Desktop (mine)
  • Surface laptop (work's)
    • Sits on a cookie cooling rack to deter overheating
  • Dell Universal Dock 6000 (mine)
    • Contains: HDMI and DisplayPort ports, USB ports, LAN; using USB or USB-C to connect to the Surface laptop
    • My three home monitors are all hooked up to the display port
    • Connected to Surface laptop via USB-C
  • Wireless keyboard (with two Windows keys, thank you very much) and mouse (mine)
  • KVM Switch (mine)
    • Only using the mouse and keyboard connectors
    • Connected to desktop and dell dock
    • Video uses VGA, and is therefore not connected - someday I might get an HDMI-oriented KVM, however...
  • Monitors - 3 Dell monitors (mine - mostly used from Kijiji)
    • Each hooked up to dell dock and desktop via HDMI and DisplayPort (yes, its a lot of video cables...)
    • Each monitor has been "programmed" so its buttons allow for easy switching of the input source via preset modes
    • 1080 x 1920; 2560 x 1600 and 1200 x 1920
  • Webcam (mine)
    • This is manually swapped between work and and home PC. I don't use it very often for home-based things, so its not really a bother
  • Headphones (mine)
    • Sony WH-1000XM3
    • Connect via bluetooth, so when swapping, re-pair with the respective computer

For working from home:

  • Laptop runs Teams, Slack, and other similar communications. All A/V goes directly through it, rather than via the remote desktop (which doesn't make sense imo).
  • A subset of monitors are used for displaying the work environment / remote desktop. See notes on how to do that here.
  • I have a powershell script on my remote machine so when RDP invariably rearranges my windows layout, it resets to how I normally use it. Maybe I'll incorporate that here one day (uses GetWindow, SetWindow), but it sounds like some people have their own setups for this.

NVIDIA's GTC 2021 Highlights

So, I haven't yet watched all these, but when the program came out, this is my hit-list of highlights for this year's FREE NVIDIA GPU Technology Conference (GTC), which ran Apr 12 - 16th, 2021. I may have simplified the titles a touch...Read more...

How to RDP fullscreen with a subset of monitors

Scott Hanselman has put together a quick and easy writeup on how to use remote desktop with just a subset of available monitors here. Should the link ever go down, I wanted to document how I use this myself, borrowing from Scott's description. Read more...
