QUESTION
I'm trying to codesign my macOS screensaver project to get rid of the "unidentified developer" warning message. Both Apple's documentation and this person on Apple's forums say that you should use the "Developer ID Application" signing certificate to do it. But that doesn't appear to work for me.
When I follow Apple's instructions on how to test for proper signatures the response I get is as follows:
...ANSWER
Answered 2019-May-26 at 03:07Just in case someone else stumbles in here...
For now I've realized that a good way around this is to create an installer package and then sign that following Apple's instructions.
I ended up using some free software called Packages to create the installer. After building the installer, I copied it to another folder and used the following command to sign it.
/usr/bin/productsign --sign "" source.pkg destination-signed.pkg
Hope this helps someone out there. As far as I can tell this gets around the unidentified developer warning.
QUESTION
I got this mac screensaver example from here.
I changed it to show image instead of textField.
The problem is this: it can show any Xcode objects such as textView. textField, Button and etc... but it cant load image on imageView. (it can load image on Xcode debug build but not on release build on mac screensavers)
Release Build Screenshot Here is my code to show image:

loads from main application bundle, but your images in plug-in, so use something like the following (load from bundle containing your class)
QUESTION
Recently I was interested in screensavers. And while I was looking for a way to write it, I found that it was supported by Xcode.
ref: https://whichline.wordpress.com/2015/07/13/os-x-screensaver-swift-2-part-1/
But my Xcode 9 does not seem to support screensaver project.
There are no way to write screensaver on Xcode 9?

I coded a C# screensaver which works in preview (install) mode, config or even test mode. However, when reaching the windows timer to launch it, screen goes black, I see the mouse loading icon for 2-3 sec and then the screen revert on the desktop.
I add a log file entry as the first line of code in my main()
and it seems like this code is never run when launched by windows.
Using Visual studio 2017 on Windows 10.
Since I am using an old 3D engine, I made sure to have the app.config modified:
...ANSWER
Answered 2017-Aug-05 at 04:34Looks like you've narrowed it down to the 3d component.
Without the log file you can be sure the application fails to start, and without an error message it's hard to diagnose why. Here are some troubleshooting steps.
Try:
- the event logs for clues,
- to 'late bind' CLTV3D using
Assembly.Load
in a Try/Catch, - running ProcessMonitor to see it says about why it's failing.
If the above doesn't work setup DebugDiag (or AdPlus with WinDbg and SOS) and analyze a crash dump.
Failing that, .Net 1.1 is like 15yrs old!!! Do yourself a favor, it will be so much easier to use an up to date library.
QUESTION
(This is sort of a crossover software-hardware topic, it started as a programming problem for me but after all the troubleshooting I think it's probably a hardware problem (maybe better suited for Super User?) but I haven't solved it yet so I don't know for sure, and hopefully this community will have some relevant cpu theory to share. Anyway...)
I'm writing a real-time rendering program and have been plagued with a visible framerate hitch that happens consistently every 2 seconds. After much profiling I've determined that this is a performance slowdown that effects all sections of code in my program (including graphics api calls), so I think it's a cpu issue that is outside the responsibility of the program.
I can demonstrate the problem on my machine with the following code in a fresh Code::Blocks project:
...ANSWER
Answered 2018-Feb-17 at 01:13The test you’ve made is way too sensitive.
On my PC it doesn’t print stuff every 2 seconds. But when I alt-tab to other app and do something, esp. access a file system, it prints a couple of lines. Even if I just sit idle and wait, it randomly prints a burst of lines every 10-30 seconds. BTW using clang 4.0 with libc++ running in Ubuntu on Windows 10, Intel Xeon CPU.
Now about your 3D rendering issue.
On your Linux PC, the absolute value of that slowdown you’ve logged is about 0.5-1ms per incident. If you like me have a 60 Hz display, 1 frame of the display = 16.6ms. By itself, that 1ms delay (likely introduced by the OS) isn’t a good enough reason for the rendering to skip frames.
Could be a problem in your code + examples code, where you construct swap chain and/or where you present stuff. Just because they’re SDK samples doesn’t mean they are guaranteed to work correctly on your particular PC.
Could be a problem with Vulkan drivers. To test this, run an OpenGL-based screensaver and look for these missing frames.
Or could just be a problem with GPU driver unrelated to Vulkan. In this case you’ll probably see the same issue with OpenGL.

I know how to add the image and the orange box, but I don't understand how I can get them next to each other. Below you'll find my HTML and CSS.

Here's the link to the whole project including all the dependencies if needed. https://www.dropbox.com/sh/3d3towtkhb4c38r/AADdxDJq9ix7bK9hTkt_VTSAa?dl=0
Basically trying to clean up some script I was left to deal with and have been banging my head against the wall as to why this isn't working. I don't get any debug errors, everything seems to be linked where it needs to be linked. My font seems to be embedded, all my instance names seem to be right... the only thing I can think of is I'm missing something silly in the code. Any help would be really appreciated! Nothing like being left a mess and having to fix it.
Basically the text box is supposed to have a countdown timer based on what race is approaching (e.g Race X is in xxx minutes) and If there isn't a race approaching, it should show some default text. At the moment, It doesn't seem to want to change the dynamic text at all!
EDIT: I'll also mention the RaceRibbon Movieclip that the text is contained in is also exported for as3 to the com.RaceRibbon class.
...ANSWER
Answered 2017-Apr-21 at 08:53I've not had a chance to test your project files but just a suggestion on elimination :
Either manually trigger setDefaultText();
or else directly target the RaceRibbon's textField (so just comment //
out the other two you aren't testing from those shown 3 lines of code).
If any Update test
below work correctly to update text then your true problem lies in either :
- IF statement of
function setCountdown():
(beforeif(mins_left > 2)
what doestrace ("minutes left: " + mins_left);
say about the amount? Does it look like it could ever become> 2
or< 3
or+1 <= 1
? If not, then your text will not update either.) - or
function checkNextRace()
(especially if you setnext_race = null;
then surely following that withnext_race = r1;
should give a debugger error like "Cannot set a value to a variable that is NULL (non-existent)" but you said you got no errors so I'm confused why mine does that.
(usectrl+shift_+enter
to debug not thatTest Movie
option).
Anyways the code...
