![]() ![]() Its cables easily detached when tension was applied to the cable, so an accidental gesture or a child wouldn't bring your $2,000 machine crashing down with it. MagSafe charging, first introduced in the 2006 MacBook Pro, was great. And while that doesn't sound like a problem on its own, USB-C was replacing the clever MagSafe charging that Apple's finally brought back with the iPhone 12. From 2015 on, MacBooks used USB-C for charging. MagSafe comes back to the Mac, and a last call at the Touch Barīut the new-and-flawed keyboard wasn't the only MacBook "upgrade" that ruffled my feathers. And I'm glad I waited, because I may be getting even more treats. And that was enough to push me into making a purchase. And when I used it, I was giddy, referring to the feeling of each keystroke as Mario, bouncing off Goombas. That Magic Keyboard made it to the Intel-based 2020 MacBook Air and 13-inch MacBook Pro. So imagine my excitement when the traditional scissor-switch keyboard came back - dubbed the Magic Keyboard - in late 2019's 16-inch MacBook Pro. Apple even announced repairs and refunds for failing MacBook keyboards, which gave me some hope. Patents began popping up, suggesting Apple was considering optical, light-based switches. ![]() Near the end of this stretch, thankfully, it seemed like Apple was starting to hear the clamor from its users who wanted it to clip the butterfly's wings. I kept thinking that I might be able to settle for one of the improved Butterfly switch keyboards, as Apple kept increasing its vertical travel. Through the years I kept telling myself "I can wait." Yet, I didn't think I was going to last this long.

Considerable attention is put into verification and validation throughout BRL-CAD. BRL-CAD includes regression tests that will compare runtime behavior against known results and report any deviations from previous results as failures. Generally there should be a compelling motivation to remove any existing functionality, but improvements are encouraged.īRL-CAD has a longstanding heritage of maintaining verifiable, validated, and repeatable results in critical portions of the package, particularly in the ray tracing library. The code adheres to a published change deprecation and obsolescence policy 8 whereby features that have been made publicly available are not removed without appropriate notification. As such, BRL-CAD maintains support for many legacy systems and devices provided that maintaining such support is not a significant burden on new development. Tenets of Good SoftwareīRL-CAD's architecture is designed to be as cross-platform and portable as is realistically and reasonably possible. The ray tracing library uses a suite of other libraries for other basic application functionality. BRL-CAD specifies its own file format (files with the extension. At the heart of BRL-CAD is a multi-representation ray tracing library named LIBRT. To support what has grown into a relatively large software system, BRL-CAD takes advantage of a variety of support libraries that encapsulate and simplify application development. These tools include geometry and image converters, signal and image processing tools, various raytrace applications, geometry manipulators, and much more. The following diagram illustrates how the number of lines of code in BRL-CAD has changed over time: System ArchitectureīRL-CAD is designed based on a UNIX 7 methodology of the command-line services, providing many tools that work in harmony to complete a specific task. We credit all contributors in BRL-CAD's authorship documentation 6. The project has historically received support from numerous organizations within academia, commercial industry, various government agencies, and from various independent contributors. Since the project's inception, more than 200 people have directly contributed to BRL-CAD. And on December 21, 2004, BRL-CAD became an open source project 5.īRL-CAD is a mature code base that has remained active over decades due to continual attention on design and maintainability. Development as a unified package began in 1983. History of the CodeĪs mentioned previously, the initial architecture and design of BRL-CAD began in 1979. You should, however, do some basic research to make sure what you plan to contribute isn't already in the BRL-CAD code base. You can generally focus in on the enhancement or change that interests you without being too concerned with other portions of the code. BRL-CAD has been intentionally designed with layering and modularity in mind. ![]() ![]() BRL-CAD provides all of the necessary third-party dependencies for download and compilation convenience within source distributions but by default will build using system versions of those dependencies if available.Īs with any large system that has been under development for a number of years, there are vast sections of code that may be unfamiliar, uninteresting, or even daunting. The project aims for an It Just Works approach to compilation whereby a functional build of BRL-CAD is possible without needing to install more than a compiler, CMake, and a build environment-for example, GNU Make or Microsoft Visual Studio. Every released version of BRL-CAD is tested and tagged. A separate branch (named STABLE) provides a higher level of quality assurance. Trunk development is generally stable, but cross-platform compilation is not guaranteed. The source code and most project data are stored in a Subversion 4 version control system for change tracking and collaborative development. BRL-CAD uses the CMake 3 build system for compilation and unit testing. POSIX 2 shell scripts are used for deployment integration testing. ![]() There is also some support for, and bindings to, other languages available. The majority of BRL-CAD is written in highly portable C and C++, with some GUI and scripting components written in Tcl/Tk 1. BRL-CAD consists of more than 1 million lines of source code spanning more than 20 foundation libraries and 400 application modules. ![]() It must end with a period, question mark, or exclamation mark.Ī comma splice, fragment, and run on do not meet the criteria for a complete, correct sentence.Ī fragment is an incomplete sentence.Native speakers of English will usually recognize an independent clause by itself as a complete sentence.Ī complete sentence must meet five simple criteria: Independent Clause: An independent clause is a unit of meaning with a subject and a verb that can be punctuated as a complete sentence. It’s important to understand how to write complete sentences and fix errors related to making complete sentences (fragments, comma splices, run-on sentences). ![]() The most common sentence errors have one thing in common: they are mistakes about sentence boundaries and what punctuation to use. But the masochist in me is going to have to wait until the story comes to a true end and we see what new torment remains in store for Logan's would-be successors.36 Mini-Grammar Review: Fragments, Run-ons, and Comma Splices With time, I'm sure rewatching all of "Succession" will be an immensely satisfying experience of brilliant television. Instead of a vindicating battle between Logan and his self-created nemeses, the HBO drama delivered a surreal validation of grief. Logan's death has been foreshadowed since the show's first episode, but the "Succession" creatives managed to masterfully sidestep every trope one might have expected from the Waystar Royco titan's inevitable downfall. It was there when Roman collapsed into Connor's arm for just a moment, or when Shiv took Kendall's hand in the hallway and Tom finally broke into tears when Greg asked if he was OK. It was there when Frank gently called Kendall "son" when the younger man was desperately in need of parental comfort. It was there when Kendall told his dad "we love you" before he said "I love you" because Roman hadn't said it. On my second watch, I was able to better see the signs of healing. A self-inflicted reminder of the wallop my heart had taken the night before, but there was something satisfying in the release of grief I knew was ahead. When I finally pressed play on the rewatch of "Connor's Wedding" late Monday morning, it was like pressing on a bruise. There's no comfort to be found in the verbosity of characters like Tom Wambsgans, who loves to employ euphemisms and double-speak during tough conversations.Įverywhere the characters turn for a comforting embrace, they only see arms spiked with past, present, and future betrayals. In "Succession," we see the worst-case scenario unfold because no one can be direct with each other. ![]() The strange way life somehow keeps moving forward even though the world just changed in a flash. There's the panic that can swing into eerie calm a penchant for dark humor to alleviate the rawness if things get too quiet. For hours, we had to watch as the people Logan had hurt the most in his life were stuck in some sort of human connection purgatory, grasping at the thin web of comfort offered by contracted employees.Įpisode director Mark Mylod used long shots and jarring angles or close-ups to help illustrate the feeling of unreality that can overwhelm people when someone they love dies suddenly. The guilt compounded, even as I made the choice.įor Logan's children, everything was wrapped up in the additional shock of grieving their abuser. I saw no upside in trying to force the moment. Whatever I did, the result was the same: I did not speak any final words to my grandmother. Maybe turned away, or actually walked in the opposite direction of her bed. ![]() Say goodbye how? Is she even there? What am I supposed to say? We could say our goodbyes before they moved her. She was still in her bed, they explained. When we got there, a kindly person escorted us to her apartment. The news had been delivered rather straightforwardly. I remember only fragments of the day she died. But then she moved to an assisted living facility, and any shot I had at a real relationship with her withered. She lived with us for a couple of years, and we'd watch golf tournaments or QVC together and eat Lean Cuisines. My last grandparent was my Nana, my mom's mom.
