If only someone could back-port Quick Look into Panther! I didn't realize how much I use that feature as I spammed the spacebar in these emulators.

Damn, I was hoping this bridge would stay in its current limbo state where it's open to pedestrians and bikes but closed to vehicles. It's so much nicer not having a five lane stroad that lets cars go 50mph into a park, and instead having a pseudo-community space.

Maybe there were thinking about it in terms of disinhibition?

    A --| B --| C

Where `A` inhibits `B` which inhibits `C`. So, while the repressor `A` is present, `C` will be transcribed. I'd imagine that simple repression is probably more common than disinhibition in gene networks, but idk.

But, it's the DM that would provide the heat/glow for the star:

> If the DM particles are their own antiparticles, then their annihilation provides a heat source that stops the collapse of the clouds and in fact produces a different type of star, a Dark Star, in thermal and hydrostatic equilibrium.

> Three key ingredients are required for the formation of DSs:

> 1) sufficient DM density

> 2) DM annihilation products become trapped inside the star

> 3) the DM heating rate beats the cooling rate of the collapsing cloud.

> I believe moderators on Reddit like to think that they're that important and integral to the site functioning smoothly, but I think the reality is upvoting/downvoting/reporting works perfectly fine in nearly every subreddit.

This seems very naive, since afaik the mods also deal (thru 3rd party apps or extensions) with the large amount of spam that reddit gets. And, of course, who is going to deal with those reports?

I mean, sure, Reddit could close everything but the top 20 or 30 most popular subreddits, hire some offshored mods, and start the content moderation speedrun[1] anew. But, why? And how bad will it get before the IPO? Reddit has spent the past two decades washing their hands of any moderation tasks, as their first party mod tools show. Starting now, with a pissed off power user base, seems suicidal.

> Sad that I had hoped some exec at Nintendo would veto this approach as "Not Nintendo" rather than choosing to tarnish the brand and take the money, like Apple did.

They did, originally. They released a $10, no microtransactions Mario game (Super Mario Run) in 2016. The general consensus is that the game did not live up to Nintendo's commercial expectations[1], and I think that's true. Nintendo entirely switched to the more standard App Store game model for its later mobile titles, and they print money.

As for "tarnishing the brand," Nintendo still hasn't really put a "full title" on mobile, with the maybe possible exception of Mario Kart. It feels like they are still keeping their distance, but who knows what would have happened if the Switch sales were more like the Wii U than the Wii.

haha yes the discourse level thread is like perfect for all us "we've read the Book" people to comment on.

you can do it that way if you wanted to

    let mut i = 0;
    for item in items {
      item.method(i);
      i += 1;
    }

I don't know why you'd it that way, but Rust definitely isn't stopping you from doing that.

e: and as running example: https://play.rust-lang.org/?version=stable&mode=debug&editio...

It looks like there was a control group:

> However, an additional control was undertaken where colour contrast thresholds were measured in the morning and then re-measured 3 h later without exposure to 670 nm. This comprised of ten subjects (six Females and four males). To determine if there were significant shifts in colour contrast sensitivities across the day that were independent of 670 nm and might undermine outcome measures for their exposure, six subjects were repeatedly tested at 0, + 3, + 6 and + 9 h (four Females and two Males).

Figure 2 shows the (lack of) effect in the no-light control group at T0 and T+3hrs. Interestingly, they don't compare to baseline like in figure 1 with the AM light group. However, Figure 4 does show a lack of training effect when repeating the same test 4 times throughout the day within the same subject.

(Also, interesting that your first response to a paper in Nature is that they don't have a control group...)

Edit: And presumably they took the design of their study into account when calculating their statistics (https://www.stat.cmu.edu/~hseltman/309/Book/chapter14.pdf). Their methods seem to imply that, but I'm not familiar with it so I'll pray the reviewers checked for that lol.

As another not-physicist who is interested in physics, I've found the articles/explainers at Of Particular Significance very helpful. There are a few on particle decay, and I think that these two provide a longer answer to your questions:

Have you read (or "read"; I don't want to be responsible for your death lol) the Texas GOP platform[1] for this year? The first sentence in the "Homosexuality and Gender Issues" section is "Homosexuality is an abnormal lifestyle choice". And they follow it up with "we oppose any criminal or civil penalties against those who oppose homosexuality".

They are rearing for another battle in the gay rights culture war.

> People play Melee with ping differences bigger than that and it works fine lol. Waaay more technical game shows that there's tolerance.

I dunno; I'd imagine people would be mad if there was a 15ms ping differential in Melee. I think the online/netplay tournament results are already looked at different than offline, console results.

Moreover, I'm pretty sure that you can't have a differential ping in a P2P game with rollback, so the competitive issues are different between the two scenes. I understand Riot wanting to equalize them. In Melee specifically, I think that the players have to decide on a common frame delay to play, right? If so, then the Melee community has come to the same solution for competitive netplay as Riot has.

hahah yes the "0.0f" is different from "0.f" is different from "0.0" is different from "0" is a great IDO meme as well. One of the changes we had to make when we started to support the PAL release, which was compiled at -O2, was to go back and change some constants from explicit "1.0f" to "1" to get the code-gen to match. IDO -O0 didn't care so long as you got the f32 vs f64 constant correct. But, IDO -O2 has different codegen.

The wonders of C constants. Sometimes IDO can do the conversion at compile time, and sometimes it can't. But, the compiler will treat things "0.0f" and a compile-time "(f32)0.0" as different constants for code-gen purposes.

We have a kinda outdated document of weird IDO behavior which is worth a read if you want to trigger some PTSD: https://hackmd.io/vPmcgdaFSlq4R2mfkq4bJg#Compiler-behavior

Also, since SGI/MIPS/IDO was from Stanford (I think...?), there is actually a surprising amount of published papers on IDO's compilation model. Which comes in handy if you are trying for the ultimate joke of decompiling the written-in-pascal compiler into C: https://github.com/n64decomp/ido

> The level of snark here is outstanding. [...] 'smelling the grass'

I thought his snark wasn't too off the charts in this video. I'd bet it's more a cultural thing. If you were working on the N64, you're probably like two decades above Kaze's target audience for his youtube videos haha. Like, he said that you can either be a weirdo who spends all day optimizing nearly 30 year old source code, or someone who "touches grass"[1]. He, of course, was referencing his own lack of life, not Nintendo's programmers. But, you'd have to pretty familiar with current online memes and insults to get his joke.

> I have not seen the Mario 64 source but I imagine some of the lowest level code was written in mips assembly but has been decompiled into C.

No, we only decompiled C code back into C code. The decompilation matches 1 to 1 with the released ROM images.[2] iirc, the only, non-libultra ASM code was the decompressor[3]. The C code was pretty obvious due to "wonders" of IDO -O0 optimization. We were forced to get surprisingly close to what Nintendo wrote. We were stuck with an `f32 [3]` 3-vec instead of a `struct`...

> I suspect the debug flags in gameplay code were to avoid compiler bugs.

As far as we could tell, this wasn't an issue. IDO 5.3 had no issues that we could find when compiling at -O2, but then again it was decompiled code. I personally subscribe to the '-O2 -g' IDO meme, but Giles Goddard thought it was out of fear of the unknown. So, I'd trust him.

We had the `mulmul` patch for IDO. I don't know the chronology for the release of that patch to devs, though. We also haven't been able to find any N64s that have the mulmul issue.

> An NTSC tv runs at 60Hz, you either hit 60fps or 30fps, anything in-between results in horrible tearing of the screen or your frames bounce between 60 and 30 and movement feels horrific.

I wonder what Kaze is doing. I know that there was work on a variable framerate mod/revamp for SM64. I'd guess it'd be outputting at the N64's 60 fps mode with duplicated frames, but you'd have much better luck asking one of the modders/coders who were working on that a couple years ago.

PD will definitely be the next game to be fully (or near enough) decompiled. The dev behind that one is great.

If you're bored, his write up on the "Challenge 7 Bug" is great read: https://gitlab.com/ryandwyer/perfect-dark/-/blob/master/docs...
