How can I increase the animation speed in Corona? Changing the sprite.timeScale property makes the animation restart.
I don't have an answer for the first question, but for the 2nd ones, we know the forum search is borked and we are in the process of fixing it, but in the mean time, your best search results come from Google. Do your google search like:
site:coronalabs.com magic formula
and that will give you the best search results until the problem gets solved.

I just want to see how exactly they work, and I can't seem to find them in either moviepy or pygame's websites. Basically I just want to see at what time a user presses a specific key during a clip, and record that time/possibly insert an image at that time while the movie is playing. I know moviepy does that already to some extent, but it's only for mouse clicks.
Thank you for your time.
I found the source code but no answer. I ended up editing the source code, and while that works, I would much rather do something else than that if possible.
To have a more elaborate answer to the rest of my question, basically it's not something I think is feasible to directly edit the video file WHILE it's playing. I also don't know if it would be a good idea to save every single and just combine them. I was able to find an extremely efficient, but niche solution by modifying the preview frame while it plays, and having that persist across every new frame. Then I saved JUST the overlay to a file, and can use that however else I feel.
I have seen no other threads/users actually deal with moviepy in this way, so feel free to PM me or ask on the thread if you want more info.

I have a file with the usual sumifs and vlookups. Nothing complicated computationally!
It has a lot of conditional formatting
As I remove the formulas the wait cursor remains there for shorter and shorter.
When I remove all the formulas and the formatting the file is fine as in I do not get the wait cursor. What is left is a file with no calculations and flat data.
Even with calculations that are just summing I am getting the wait cursor
I have tried excel open and repair. This does not work.
My sumifs have been changed to refer to a finite array as opposed to whole columns (which are also finite for the pedantic! but say these are infinite)
I think what I want to know, is what is known to cause a wait cursor to appear in excel? What can I do to minimize the time that the wait cursor appears?
I have looked on google and am not finding anything useful or relevant to my problem
I am starting to realise that wait cursor seems to always appear for a split second when I insert a column! however with my few sumifs formulas the wait cursor is getting longer and longer. Is it possible for sumifs formulas to calculate quickly but add to the wait cursor time the more sumifs you add?
Old question :
I have an excel file that keeps freezing
It calculates and saves very quickly. it is only 3090kb
Every time I insert a column or add a sheet for example I get the egg timer and if I click it starts to say 'not responding'
It only happens with this file so I don't believe it is my computer or excel version
the file was working fine before. I extended the formulas in about ten tabs (although not that many calcs added) and then it started to freeze
even if I delete every tab so there is just a blank sheet in the file it still freezes
Please help. Thanks
Please do not answer yet, I am still investigating and will get back to this. thank you
EDIT: The WAIT cursor not egg timer
Check if there are any hidden sheets with the data that is slowing it down.
Right click on sheet tab and unhide.
Make this practice to use this Macro or set Row Height to 15 so they don't Wrap. Wraptext in large excel files causes it to slow down to the point of freezing:
activesheet.cells.wraptext = false
#Jasmine - I wasn't suggesting that you are making anything up, nor was I my comment intended to be facetious. My point was that your question sounds self-contradictory to me.
When learning a new coding language, learning which questions to ask and how to phrase and share your problem is a skill in itself.
The fact that your file functions (a.k.a. calculates) 'properly'
until more identical formulas are added, sounds to me like it's no longer calculating properly, so I was unsure what you meant.
As for the `size doesn't matter' comment, it's another valid point about how some people ask questions when mistakenly thinking that file size has any significance. I've encountered and solved thousands of [seemingly unique] issues over the years but the last time I looked at the size of my file would have been back when it would've had to fit on a diskette.
Similarly, I often see questions here where the "asker" includes irrelevant statistics like the number of records in their database, as if you need to code differently for 10 records versus 10,000,000 (which isn't generally true, btw). I can't help but chuckle at some questions where the O.P. spends more time describing the formatting of a cell than the formula it contains (that's causing the issue). But from their point of view, it's significant.
Think of the people reading your question as sitting in your office blindfolded while you explain your problem. If you're asking for (free) help from others who cannot see what you can, with zero previous knowledge, does it not make sense to make a question absolutely as clear as possible -- even if that involves Googling a word to update your terminology that you know is incorrect? (or is the onus on the reader to figure out what you mean?
**Did you click the links I posted for you (above) to learn how to better communicate your problem and edit your question to add more specific examples and more information as requested and described in those links? (or was that a "waste of time" as well?) There were specific questions for you as well.
This site was frustrating for me when I first joined too but the rules and posting etiquette were not made immediately known to me by a stranger with a few seconds to spare. I had a major learning curve and some pretty nasty comments from people since I was breaking rules I wasn't even aware of. I am actually breaking a major rule right now, can you identify it perhaps by familiarizing yourself with the site in the Help Center?
Hint: I'm probably going to get "scolded" for the method I am using to give you this advice as opposed to the short comments and links I would normally post on a question that needs more information so I or others can give an informed answer. Some people don't like posting a question and not getting a custom written set of code promptly written just for them. Some people are grateful for every bit of advice they can get from a stranger, others never come back and find a site more suited to their needs.
Remember, there is a ton of existing information on this site and others because it's very unlikely that whatever problem you're having has been experienced - and solved - by many, many people before you. By researching as much as possible, you learn both about your problem and about which questions get "better" answers than others.
Anyhow I hope you read fast, this answer might not be here long (I wanted to be clear but without a whole whack of comments back and forth...)
Jasmine, if you're still angry with me, you can "get me back" if you can find the correct Flag button. The answer to my question for you in is there too... (It's not option #2, as lest not intentionally!)
Good luck & happy holidays to all!
Have a look at moodi.org, sony.com/be-moved, http://www.spaceneedle.com/home/,
. How can i make site like this?
Basically, it's all done by detecting user's scrolling amount, and moving things accordingly.
You need some JavaScript and of course html & css to achieve something like that.
What JS does is that it detects if user is scrolling, it's direction and speed, then tells object "A" to move at the opposite direction of scroll, and also at 0.8 speed of it. Object "B" moves at the opposite direction but with 1.2 speed of scrolling, so You'll feel like object "B" is closer to you.
This is just a very simple example on how it works.
Remember to have a good scenario before touching the code, and while coding, break your problems into small pieces and look for them in here,
For example: How to change position of absolute element based on client scrollTop?
That's how you'll learn.

There are many technics, to make something efficient and clean, you need to be familiar with them to make the best decision.
Here are some links which help you start:
This is somehow old, but I think helps understanding the concept : http://ianlunn.co.uk/articles/recreate-nikebetterworld-parallax/
https://ihatetomatoes.net/how-to-create-a-parallax-scrolling-website-part-2/
Css-only approach : http://keithclark.co.uk/articles/pure-css-parallax-websites/
These are just some starting points, of course you can find more tutorials and even look through source of your favorite websites to see how they achieved the effect.
Final note : I think one important thing to bear in mind is not to move many objects at the same time, once they are off the viewport, stop moving them, this helps a lot when it comes to performance specially on older machines.
jQuery Waypoint is a handy tool, which is introduced in the second link.
I am applying A* (and IDA*) search with manhattan heuristic for finding solution to 15-puzzle problem.
Using the fact that i dont want an optimal solution for the problem how can i can speed up the search as the current routine is too slow.
Well, it's not exactly a solution, but it might help. Once I've been working for a HOG game with that same puzzle as a minigame and it turned much easier to generate a problem, than find a solution.
What I mean is, we can turn a solved puzzle into unsolved by randomly moving "window" according to rules. And logging each field position for future use. Then we let user play a bit and if she gives up, we can solve a puzzle for her easily by finding the common position in user and our log. We just play back via user log to the common position and back from it to the solved position via ours log.
Of course, this is a hack and not a real solution, but it works fine in gamedev. And not only for this particular game. Most repositioning puzzles can be "solved" this way.
This is really unknown issue to many people. I would raise a question for it and make it easily accessible for other, and maybe someone of you know the solution for this problem.
All of us probably know that there is problem with alpha transparency in PNG24 in IE6 (still used by many people on web..). There are at least few known solutions how to solve that, but all of them got their problem that I would like to describe there:
1.Using progid:DXImageTransform.Microsoft.AlphaImageLoader:
This is most common trick to make images shown in IE6. Problem is that it uses DirectX to show it. So basically DX firstly need to download file from Net, then render it. This downloading block browser context for a while. But if you have alot of images - that means that you page can be freezed for even... few minutes (it happens to mine one project at least once).

http://www.stum.de/2008/12/01/do-not-use-alphaimageloader-to-fix-transparent-pngs-in-ie6/
2.Using VML.
You can also use this workaround. However this has a nasty effect of rendering gray box in background, then a proper image, also causing to download image files twice - this however might be because of bad implementation so need to be checked.
3.Using PNG8.
Just forget about solutions and try use PNG8, if prepared correctly can still be looking good.
If anyone knows any other solution please give answer here!
