old lenses – Were “shutter speeds” for cameras really in the hours back in the day?

https://en.wikipedia.org/wiki/Shutter_speed

I can’t find any mention of it here, but once I read in a printed comic book, where there was a page of “weird facts”, that in the beginning of photography, people had to stand for literally hours, as if somebody was painting a painting of them, for the camera to take the photo.

Is this utter nonsense? If this was ever the case, why on Earth was that ever necessary? I’ve gone through my entire life assuming that this was the case, but maybe it was one of the “fake facts” which tried to trick the reader. (Yes, they had at least one such every week until they stopped having those pages.)

Which were the first iOS devices to charge at faster speeds when connected to a 12W USB power adapter?

I’m aware that fast charging via USB-C is a relatively new feature for iOS devices – but out of interest, I’m wondering which iOS devices were the first to support faster charging when connected to a standard 12W USB power adapter – either via Lightning, or the legacy 30-pin dock connector.

dnd 5e – How do multiple speeds interact with jumping in D&D 5e?

I have a question regarding the interaction of the Long Jump rules (PHB, p182) and the Using Different Speeds rules (PHB, p190).  The first paragraph of the rules for long jumping concludes with this sentence:

“Either way, each foot you clear on the jump costs a foot of
movement.”

My initial thought was to assume “movement” here means walking speed. However it becomes ambiguous when the jumping creature lacks a walking speed, or has multiple movement modes. Is jump distance meant to be constrained specifically by walking speed, or can each “foot of movement” be subtracted from other speeds?

I see three possible interpretations:

1. Jump distance is subtracted from your walking speed only.

2. Jump distance is subtracted from one of your speeds (but not necessarily walking speed).

3. Jump distance is subtracted from all of your speeds simultaneously.

Option 1 results in a world in which many aquatic creatures cannot jump at all, so I don’t think it makes sense.  I think option 2 makes the most sense, but also leads to some odd results at the extremes.  Option 3 has the same problems as option 1, and also is problematic because it essentially double-counts the jump distance against every speed.

As an example: a dolphin has a strength of 14, a speed of 0 feet, and a swim speed of 60 feet.  Could a dolphin swim 10 feet to get a “running start” before jumping 14 feet horizontally out of the water and through the air (subtracting this distance from its swimming speed)?  I would presume that dolphins can use their swimming speed instead of walking speed for jump distance, because the alternative would be that dolphins cannot jump at all (as they would be constrained to a distance of 0 feet by their walking speed).

Now, let’s complicate the example by introducing multiple speeds: A giant octopus has a strength of 17, a speed of 10 feet, and a swim speed of 60 feet.  I would assume it could jump in a manner similar to the dolphin using only it’s swim speed – but what if it were on land?  Could the octopus use its 10 feet of walking speed to get a running start, and then jump 17 feet horizontally (subtracting the distance of the jump from its unused swimming speed)?

Another example involving climbing speed instead:  Can a brown bear (strength 19, speed 40 feet, climbing speed 30 feet) run 40 feet and then jump 19 feet horizontally (subtracting those 19 feet from its unused climbing speed)?  Or, to go the other way, could it climb 30 feet up a tree and then jump 19 feet horizontally (subtracting the jump distance from its unused walking speed)?

So, which interpretation is correct? Or is there another interpretation I’ve missed?

windows – Huge difference in transfer speeds when using separate directories for transfer

I was transferring around 12k images (total size around 2 GBs) from my laptop to my Android phone via USB. Initially, it was around 5-6 images copying per second and soon after around 500 images speed began to drop and reached more than 5 seconds per image. I tried copying them in batches of 500 images but that was no better. It was like the more the number of files in a directory the slower it is to add more to it.

Then what I did is make separate folders in the same directory and copy only about 500 images at a time to each. This way I got speeds of 5-6 images per second similar to what I was getting initially when I was transferring them all at once to a single directory. Later, I simply moved the images out of those folders using native file manager in my phone, which was almost instantaneous.

Why is that speed was decreasing exponentially when I was copying all files to the same directory?

Web Hosting – Is There Any Way To Find Out If My Host Is Limiting Speeds By Request Threads?

I have been with my host as a reseller for almost 15 years and recently I have noticed the slowness of my hosted sites. I've always attributed it to isolated cases or a slow connection on the user side … but after so long, it seems suspicious.

Of course, contacting my host did not help, they just kept saying there was nothing wrong with their service.

So I did a test using the site speed tools and my page of around 3MB takes around 15-20 seconds to complete!

looking at the external sources being loaded, yes, of course, there are a bunch of http requests (js, api, etc.) but these are just very small datasets.

To make a long story short, I noticed something.

Loading a very basic HTML site with a bunch of statically coded images in the doc is extremely fast …. but loading a similar site, slightly heavier but with lots of sources external (from the same host) is super slow … and I noticed that, using Firebug, although a bunch of AJAX and Image requests were triggered, I can see a lot of these threads crashing or stop and continue when the other threads are finished … it is as if the server is slowing down in one way or another down my page load, or some of his sons, as a means of managing bandwidth?

If I load other bigger websites like Amazon, eBay, Facebook, with as many or even some smaller websites not using AWS but loading a bunch of external assets, and I see the threads request to load or progress at the same time … some sites with a total loading of 8 MB of pages in less than 2 seconds and my site with only 3 MB reaching about 15 seconds to complete.

I would like to know a way to
1. determine if my host is sneaky with its bandwidth by slowing or limiting concurrent thread loads.
2. document or prove to them that this is the case.

Is there such a way?

macos – What download speeds is Apple USB Ethernet adapter capable of?

I have a 2014 MBP running 10.13.6.

The first two photos show my basic Ethernet performance, with the desktop application Speedtest and Fast.com, respectively. I get this with wireless, Ethernet → Thunderbolt (Apple Thunderbolt Ethernet Adapter), and Ethernet → USB 3.0 (Monoprice (Realtek 1853) USB Ethernet Adapter).

The next pair shows what I get with the Apple USB Ethernet adapter (plugged directly into a USB 3.0 port on my Mac).

Other info:

In System Report → Hardware, the Apple adapter is listed as "Speed: Up to 480 Mb / sec", and in System Preferences → Network → Advanced → Hardware, it says "Speed: 100baseTX" and "Duplex: full- duplex, flow -control ".

On the other hand, for the Monoprice adapter (Realtek 1853), it is indicated "Speed: up to 5 Gb / s", "Speed: 1000baseT" and "Duplex: full duplex" (no flow control ).
My question: it seems that Apple's USB Ethernet adapter should have a cap of 100 Mbps (100baseTX) or 480 Mbps. But I only get download speeds of 30 Mbps with the Apple device. What should be the actual performance of this device?

game design – Implications of variable 2D execution speeds

I get my feet wet trying to design and implement a 2D action platform game. Combat will be a high priority, so I want to have tight ground and air control so that players can be precise and express their mastery. For now, I don't think I want high acceleration and deceleration times, as I think they are detrimental to a “ tight '' control scheme ; but feel free to correct me if there are data or examples that say otherwise.

I get a lot of inspiration from combat and I want it to look like a fighting game. From a surface level analysis, in many fighting games, including Smash Brothers, there are usually two (or more) horizontal movement speeds – a walk and a run, a run and a sprint , etc. Naively, I thought "fighting games have it right, so if I want it to look like a fighting game, I must have it too", but when I think about it a little more, I don't not know if it is worth implementing. Mainly because I don't understand the implications of having a sprint mechanic or not.

One thing I quickly discover is that any design question can be summed up as "it depends", especially on the game itself and what I want to accomplish. If you need more context, my initial idea is to more closely match the feelings you feel when you take out a new combo or link or discover new ways to use system mechanics in a game. fight with that sense of discovery by opening a game. world in a Metroidvania. So a 2D metroidvania with action / combat level fights. My initial thought is that sprinting would open up the possibility of dashboard attacks, maybe a few cancellations, and make it easier to move around the world. It also means more implementation work, since I'm mostly short of buttons, so I would have to do some sort of double tap or smash-attack analog input to make it work.

My main example of two running speeds in a non-combat game is in some Kirby games, where you can start a dash by double-tapping a direction. In the context of Kirby, what does the dash do for the game as a whole? Would it be better to have a faster basic walking speed and no dash? What opportunities would open up if I had a sprint and what would become of me closed?

Perhaps a better example, but not in 2D, is Raiden from Metal Gear Solid Rising Revengeance's Raiden. This helped him move from one meeting to the next more quickly and served as a means of filling the gaps under fire.

The initial reaction says that my players will just use sprint to run from match to match and will miss things I put in if they wouldn't take their time. I should put stuff that encourages the player to slow down, and be smart about it so that I don't feel like I'm beating the player's pace. I think “ go as fast as I can & # 39; & # 39; is the default mode for most players, and having a variable running speed doesn't really add a lot of choice. I think going fast, especially going faster in comparison, is fun, but is it a valid compromise? I could compensate for that with an endurance system just for sprinting or some other artificial limiter, but I think it opens up a whole new set of implications that I don't understand even better.

TL; DR

What are the pros and cons of a sprint?

Who is the cheapest and most reliable to give me the speeds I need?

I need a line dedicated to 1 Gbps, (preferably 2 Gbps so up / down etc.) on a simple Ubuntu server.

Preferably takes cryptography
