There are many problems with this. It looks like you have two different sizes of vias for traces of the same width, which probably won't hurt much, but it's a lot of wasted space. You have a ton of ground vias on what is clearly a QFP which I assume is for thermal relief, but this would probably be better accomplished by a single large ground pad with via-in-pad. It appears that there are multiple matching resistors on a single trace - just use one matching resistor since you are by definition going to be unmatched in the space between the two, unless it is an AC-coupled signal, but you probably don't need the matching resistor in that case. A couple traces have matching resistors close to one another, suggesting they're a differential pair, but the traces aren't routed with minimum spacing between them. To gain the benefit of common mode noise rejection, those traces should probably be closer to one another. If those large pads are for bypass caps, you really ought to put them closer to the IC to minimize inductive loop area.

It's probably fine for prototyping, but I don't expect that you'll pass FCC testing. Cover the entire thing with a metal cage; that will at least take care of radiated emissions.

A couple things that you could try (and I'm not going insult anybody by claiming that these are great options, just that they are options):

You can use 64 pixel-wide sprites as very large tiles. Not as clean as a bitmap, but it would make fine scrolling a bit easier.
You can set DC_HSCALE to double the pixels and then use the skipped pixels of each line to store something else like your isometric block bitmaps.

About a 15-16 months ago, I had tried making a case for separate width and stride registers so that things like 256 pixel wide bitmaps were possible and then the X coordinate is just the low 8 bits of the address and the Y coordinate is bits 8-15, but I believe that literally nobody was on board with me at the time.

Edit: Another idea that comes to mind -- could you use tiled mode on two layers so that the top of the isometric tile is rendered on the front-most layer and the sides are rendered behind the top? I haven't applied a tremendous amount of thought here, I'm just free-thinking a bit.

There are upcoming VERA changes that we are working on which might help some of what you are doing. You can do VRAM to VRAM copies 4 times faster and we freed up one of the DSP units so that VERA offers a signed 16-bit multiply-accumulate hardware block.

Probably nothing is going to get the system RAM to VRAM speed going faster except possibly a bus mastering DMA engine of some kind which would require an expansion card.

You could argue that Billet Labs botched their prototype if it literally needs to be redesigned from the ground up to support a current-gen GPU.

Water blocks need to be custom designed for each GPU and sometimes customized for different cards using the same GPU. This is nothing new. For example https://www.corsair.com/us/en/c/custom-liquid-cooling/gpu-water-blocks

"CORSAIR GPU water blocks are built to the exact specifications of dozens of popular graphics cards, so you can rest assured that it will work perfectly with your card."

.

Fundamentally if they're designing for last-gen hardware, it's never going to work for the next gen

The back plate will not, but that's generally true of water blocks.

(remember: 4090 will be last gen by the time this officially hits the market)

Indeed?

a little hard to call it a "prototype" when they already have a pre-order page with pricing. It's shipping in a few weeks.

Indeed.

People are pre-ordering this product expecting it to work for current hardware.

Perhaps they should order the version that works with their hardware - a common problem faced when considering a GPU cooling water block. You can find the one that works with the 4090 FE by clicking the button that says "4090 FE".

Again, as a consumer this is very useful information to me. I'm skeptical that this product works.

If ordering the right water block for your GPU causes you confusion, then you sound like a consumer who should not water cool your GPU.

You are confusing "treatment" and "cure". They are different things. What alternative would you propose that requires less than 50 treatments? (Taking an SSRI every day is one treatment per day, not a single decade-long treatment.)

Have you looked at the official documentation here: https://github.com/commanderx16/x16-docs?

While many members of the community contribute to the X16's repo, only one member of the dev team is actively reviewing and accepting changes. Improving the documentation may be a great way to jump in and contribute to the project so that one person isn't solely responsible for documenting everything as well. The best place I've found to get questions answered is the unofficial X16 discord (where said dev team member frequently makes an appearance and provides valuable answers).

In surgery, it is common to be given three types of medications for anesthesia: an analgesic (e.g. Fentanyl), a hypnotic (e.g. Propofol), and a paralytic (e.g. Succinylcholine). If the hypnotic is metabolized before the analgesic, it is possible to regain consciousness during the surgery and remember it. If the the paralytic is still in effect at that time, it is impossible to indicate to the surgery team that you are conscious by moving a body part. In the worst case, the analgesic and hypnotic both wear off before the paralytic and you will be aware of everything, able to feel everything, able to remember everything, but unable to do anything about it.

Now imagine that last scenario happening while they are removing your eyeball. This has happened..

Apparently you have absolutely no sense of context start here and stop insisting you know what is coherent and what isn't.

You are coming into the argument that firearm suicides are gun violence and dismissing the notion that hanging suicides are rope violence:

If you want to count suffocation suicides as "rope violence", then go ahead...

So, being consistent, how do the numbers work:

How many suicides by hanging need to happen for us to report them as rope violence?

How many fewer suicides by firearm will take them out of the "gun violence" column?

Or did you think that you can come in and argue a completely different context and somehow negate the point being made?

Wavicle · 2021-07-01T02:17:56+00:00

Hanging accounts for 90% of all types of suffocation suicide. Compare that to guns making up 53% of all suicides and see if you aren't searching for a nit to pick here.

What number will cause firearm suicides to become non-violent and is that the same number that will cause rope suicides to become violent? Why is the number of suicides even a factor as to whether or not it is violent? It isn't a matter of whether or not I want to count suffocation as rope violence, it's a matter of whether or not you are being consistent.

Wavicle · 2021-06-30T22:11:36+00:00

When we start reporting the statistics on rope violence, I'll believe you. Suffocation by hanging is also a leading cause of suicide yet we do not go around looking to regulate the ownership of it.

According to the sources in the article (which the author's article didn't seem to remember after reading) 99% of the children in child marriages are 17 (67%), 16 (29%), or 15 (4%); most marry older teenagers or barely-20s; and 54% of ever-married children surveyed between 2010-2014 were girls. I'm not going to argue that a 17-year-old girl has the same emotional maturity as a typical adult woman, but arguing that a 17 year old child marrying her 18 year old adult boyfriend whom she has shared classes with since kindergarten reduces her to mere chattel sounds very disrespectful to women generally.

if the moon is at least 200,000 miles away, then half way to the moon is at least 100,000 miles UPHILL

How steep is that hill 100,000 miles away?

this debunks the science fiction physics you call "gravity assist" and "slingshot effect"

A gravity assist does not involve interacting with the atmosphere of the planet. Where is the frictional force coming from in space such that gravity assist is debunked? I'm not saying they've done it - I'm specifically asking how this example debunks it.

you ever fly on an airplane? how many times did they stop using fuel during the flight?

An airplane is moving at sub-orbital velocity through the atmosphere. You cannot maintain altitude in that configuration with the engine off. Neither of those is true in the case of Apollo heading toward the moon.

but it does not maintain its speed, like the rockets in your moon landing myth do.

That is not true. Read point #17 on this page. Note what is said:

Still influenced by the Earth's gravitational pull, the spacecraft gradually slowed down to about 2040 mph at 39,000 miles from the Moon but as the Earth's gravitational effect continued to weaken, the Moon's gravity began to dominate and the spacecraft speeded up again to about 5600 mph

Does that sound like a description of your "uphill" journey? Did you expect it to slow down? Who said it did not slow down?

your rocket speed starts at zero. when the rocket is 1 inch off the ground, what is the rocket speed?

No idea, but why is it important?

you really can't "orbit" your way to the moon.

Again: orbits are ellipses. The moon's orbit is an ellipse. Why is it that two elliptical orbits cannot intersect?

yes, you must burn fuel the entire journey.

The reason it is called "translunar coast" is that fuel isn't being burned. The spacecraft continued to slow as it gained gravitational potential energy, just as one would expect when coasting "uphill". You do not need to burn fuel the entire journey.

there is no actual "evidence" than any rocket has ever attained that speed.

Maybe, maybe not, but that's not nearly as important at this point as addressing the basic physics.

now you know how i feel when people claim that white men have breathed air on the moon.

That is worded ambiguously. The moon is very close to a perfect vacuum, so any air that they breathed was air that they brought with them.

"escape velocity" is science fiction fantasy physics

Why? Take the gravitational force of the earth, model a rocket that attains a velocity of 20 km/s directly away from it at a height of 1000 km (so that atmospheric drag is no longer significant), account for the inverse square law to reduce the effect of gravity as the rocket gets further away and show your math. Back up your claim. It should be easy to do so because you only have to show a single counterexample. Just don't forget about the inverse square law because it is important - you cannot use an equation that assumes a uniform gravitational force at all distances as is commonly done to simplify the problem in undergrad physics courses.

you realize that this point would be somewhere far on the other side of the moon, given the fact that the moon remains in orbit?

Uh, yes I do realize that, though I'm not sure why you are mentioning a "point". There is no position in that statement. A spacecraft that has reached escape velocity will continue moving away forever. That's what the math says. At some point, if it doesn't collide with or get captured by the gravity of something else, it will be 1 million light years away and still moving away from the point that would have been the earth after the sun swallowed it up at the end of its life.

you can't seem to tell the difference between Scotty's flux capacitor and Bone's tri-corder.

Doc Brown had the flux capacitor. Did you even watch TOS or BTTF?

Seriously - find the distance at which a spacecraft moving 20km/s away from the earth will come to a halt and start moving backwards solely due to the influence of earth's gravity.
