"It's too hoooottttttt." B( [From Kounosuke probably taking place in summer :3c]

"Yeah it's pretty hot around here. Sound like we got an excuse to cool off."

*Otto's cybernetics kept his body temperature set so he wasn't too bothered by extreme hot or cold much, but he could understand how others might be bothered by it all. Plus, it does give them both an excuse to cool down somehow.*

Rust Compiler Performance Triage

Overall a fairly busy week, with many improvements and regressions, though the net result ends up being a small regression. Pretty busy week in terms of regressions in rollups as well, which unfortunately mostly were not followed up on prior to the report being put together, despite the relative ease of running perf against individual PRs now.

Triage done by @simulacrum. Revision range: 1e926f06..e0f8e60

2 Regressions, 4 Improvements, 4 Mixed; 4 of them in rollups 47 artifact comparisons made in total

See full report for details.

Call for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:

No RFCs issued a call for testing this week.

If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

Approved RFCs

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:

No RFCs were approved this week.

Quote of the Week

I think it's worth noting that the fact that this program fails to compile whereas the analogous Python runs but gives the wrong answer is exactly what Rust's ownership and borrowing system is about.

– Kevin Reid on rust-users

Thanks to Kill The Mule for the suggestion!

How long is a day on Shuggazoom compared to Earth? Also when Otto's traveling through space, does he ever get jet lag?

"If we want to go off of what most people define as a day, I would say Shuggazoom's day and night cycle lasts similarly to Earth's. And at this point, I am pretty used to traveling in space, so I don't get so called, 'Jet Lag'."

#Otto's Q&A (Asks) #IC #hyperqueue

[greenmechanicalgenius]

"Bicycles are cheaper than cars and still get you where you wanna go. I'm not sure about other places, but in Kazenari there are paths specifically for people to ride a bike to their location."

"Shuggazoom has paths for that and bigger vehicles, both on ground and more of what you might consider more futuristic."

*The green simian smiled, sitting with the tanuki as they were enjoying the scenery. He had taken to lean against the bigger of the two without much thought. He didn't really notice what he was doing and Kounosuke didn't say anything either. He was just enjoying the day with someone he truly cared about. What was wrong with that?*

"I will say this, this place definitely beats my home in the natural beauty department though. I can see why you like this place. Hopefully you'll get to see my home as well and then you can tell me how you feel about it. I can even take you through one of the biking paths if you really want."

#gonnachasethestars #IC #hyperqueue

[greenmechanicalgenius]

@gonnachasethestars Continued from: (x)

"Well...I think it's time I told you a bit more about...What I actually do for a living...If you call it that. Perhaps it will put the tales of my adventures a bit more into perspective."

*He would smile back and sit down next to Kounosuke on the couch. He was nervous of what the other might feel after hearing all of this...But he felt he needed to tell the tanuki. He deserved to know.*

"I just want you to know so you can decide how you best want to move forward with our... bond."

Maybe he shouldn't have laughed at it, but there was something humorous to the hero about seeing his pet hawk peck uselessly at the other's helmet. Seems she was confused about what Otto was but, hey, no harm no foul, right?

"Ignore her, she just doesn't like robots. Or people who look like them."

"Well I hope she doesn't end up pecking at something important...Or high voltage." *It was true. She could do that. Then again, the hawk probably knew better if she recognized him as a robot.*

"Then again, most people do think we are robots. We go along with it because it's easier that way. We're more akin to cyborgs really. Theoretically with a bit of work we could abandon our cybernetics but that goes into a bunch of procedures that aren't one-hundred percent full proof and all. Beside, I'm too accustomed to them to want to live without them."
