A LSP client maintainer's view of the LSP protocol. : vim
the author of YCM is not happy with LSP: there's the usual MS "claim it's standardized, then break in areas", but nothing that can't be fixed.
However, the deeper point is that vim and vim's completion is probably incompatible with how LSP works. Note the comments on r/emacs on how they're working with LSP OK in company-mode:

"This assumes the use of go modules (which will be the default for all Go builds as of Go 1.13) and vendoring (which reasonable minds might disagree about)."

Blobs in Games: Verb-noun vs noun-verb
Starts with interesting stuff in the Ultima games, then goes into vim and auto-complete.
"In games it seems like it'd be better for players to first choose an object from the environment and then choose from a small set of actions, than to first choose from a large set of actions and then choose from a set of objects. However I haven't surveyed enough games to see what's more common. The next time you're playing a game, look at the structure of commands to see if it's verb-noun or noun-verb. "

Plan 9 admittedly sucks in many ways. It has limited hardware support, a weird u... | Hacker News
"To draw to the screen there is one function: draw(). You pass it two rasters and some coordinates and it draws one on top of the other. That's it. Everything works across networks and architectures."

"The thread library is wonderful. Threads in Plan 9 are non-preemptive and run in a round-robin fashion. They communicate using CSP channels. CSP can greatly simplify the design of many programs."

"In a few of the programs I wrote would access the mouse and keyboard in seperate threads. You could use the regular open() and read() calls from each thread and there was no need to worry about locks. When I wanted something to run on both cpus I forked a process, which is very cheap."

PR: "In linux and windows programs are islands. These islands are expected to provide everything the program does in one executable. Acme is not an island. It does not have a builtin spell checker or word counter. What it does have is a namespace that allows you to access its resources."

Pointer Based Data-Structures in SPARK - The AdaCore Blog
"The specification and verification of pointer-based data-structures is a challenge in deductive verification whether the 'pointer' part is implemented as a machine pointer or as an array index (as an example, see our previous post about verifying insertion inside a red-black tree). In addition, SPARK has a strict ownership policy which will prevent completely the use of some (doubly-linked) data-structures, and complicate the writing of usual algorithms on others. However, I think I have demonstrated in this post that is still feasible to write and verify in SPARK some of these algorithms, with comparatively few user-supplied annotations."
Note how they're borrowing some ideas from Rust.

Underdiagnosis of Attention-Deficit/Hyperactivity Disorder in Adult Patients: A Review of the Literature
Must read in a desktop browser.
"Almost every aspect of adult life can be impacted by ADHD, including work and family life, particularly if the condition remains undiagnosed, untreated, or ineffectively treated, potentially with a detrimental effect on psychological well-being and quality of life. Conversely, some adults with ADHD may appear to function normally, although they might expend excessive amounts of energy trying to overcome their impairments; this may also affect their psychological well-being, as patients are distressed by persistent symptoms such as restlessness and mood instability."

How my application ran away and called home from Redmond
"Microsoft Windows 10 sends all new unique binaries for further analysis to Microsoft by default. They run the executable in an environment where network connectivity is available. This opens interesting data leak vector for attacker and also includes some privacy concerns. It is quite common that even in isolated environments, many of the Microsoft IP address ranges are whitelisted to make sure systems will stay up to date. This enables adversary to leak data via Microsoft services which is extremely juicy covert channel."

An Introduction To Real-Time Subsurface Scattering
'If you were to ask me right now to choose between the 3 techniques that I discussed, I would probably go with the screen-space option. In general it seems to have the least corner cases to handle, and most closely resembles a ray-tracing approach. But that could also be a bit of "the grass is always greener" syndrome on my part. I also fully expect a few games to start using ray-traced SSS on high-end hardware at some point in the near future, since you can use that for high-quality results while keeping a screen-space path as a fallback for weaker hardware'

Vagrearg - Fast HSV to RGB Conversion
"Using a different color-space than RGB makes coding functionality much easier, but it comes at the expense of a more or less complex calculation to convert the color-space used in coding to the LED controlling RGB color-space. Therein also lies the problem, small micro controllers are unable to perform complex calculations without significant resources, which usually means increased calculation time."

A Rant On Terra
"You realize now, the monstrosity we unleashed upon the world? The sin that Terra has committed now lies naked before us.

Terra is C if you replaced the preprocessor with Lua.

Remember how Terra says you can implement Java-like and Go-like class systems? You can’t. Or rather, you will end up with a pathetic imitation, a facsimile of a real class system, striped down to the bone and bereft of any useful mechanisms. It is nothing more than an implementation of vtables, just like you would make in C. Because Terra is C. It’s metaprogrammable C."

He Never Intended To Become A Political Dissident, But Then He Started Beating Up Tai Chi Masters
"There’s an unmistakable whiff of pro wrestling surrounding Xu’s entire project. Part of this is down to the fact that he can deliver monologues like a seasoned heel; part of it is because, for as seriously as he takes his fights against tai chi masters, there’s a slapstick quality to each of them. There’s just something inherently funny about watching an aging, chunky MMA fighter stride right up to a supposed martial arts master and proceed to beat the absolute hell out of him.

Of all the absurdities that have recently defined Xu’s life, none are seemingly greater than the fact that he, a loudmouthed fighter and entertainer with objectively modest political views, has become a real symbol of dissent. But perhaps that’s not so absurd. In modern China, the simple act of being brash and unapologetic can be enough to qualify one as a true rebel."

"This small Alisia Dragoon interview originally appeared in BEEP Megadrive magazine and features staff members from both Gainax and Game Arts. It presents a very different picture from the Game Arts which would later be known for the Grandia series; in many ways, it was the last hurrah for the development of Game Arts’ first action series, Thexder (note the involvement of Thexder/Fire Hawk co-creator Satoshi Uesaka)."

"This interview also focused heavily on Game Arts’ new software tools for map/sprite editing, “KETCHUP” and “DARI”. I’ve included several images which offer an extra window into both Alisia Dragoon’s development specifically and the Game Arts working environment generally in 1992."

Nearly all data structures with cycles need to allow multiple references to the same object, which unique references cannot do.
