"In Android, a possible black screen may occur as switching activity",

Launch to B from A.\n\n03-06 13:04:52.811: I/LOG(32125): pause A begin\n03-06 13:04:53.811: I/LOG(32125): pause A return\n03-06 13:04:53.813: I/LOG(32125): focus A begin\n03-06 13:04:58.813: I/LOG(32125): focus A return\n\nIn the window, shows the view of Activity A.\n\n03-06 13:04:58.829: I/LOG(32125): create B begin\n03-06 13:04:58.845: I/LOG(32125): create B return\n03-06 13:04:58.846: I/LOG(32125): start B begin\n03-06 13:04:59.847: I/LOG(32125): start B return\n\nThe view of Act A is hide, it is now shown by Activity B, but it's actually a \"black screen\" rather than the \"actual genereated layout\" in Activity B\n\n03-06 13:04:59.847: I/LOG(32125): resume B begin\n03-06 13:05:00.847: I/LOG(32125): resume B return\n03-06 13:05:00.968: I/LOG(32125): focus B begin\n03-06 13:05:05.968: I/LOG(32125): focus B return\n\nUntil this point, the \"actual generated layout\" of Activity B is shown here.\n\n03-06 13:05:06.044: I/LOG(32125): A onSaveInstance\n03-06 13:05:06.044: I/LOG(32125): stop A begin\n03-06 13:05:07.044: I/LOG(32125): stop A return\n\n\nBelow is the code in my Activity A & B. I use Thread.sleep to simulate the long period task. ( Maybe this is not an appropriate way make the simulation? )\n\n@Override\nprotected void onStart() {\n super.onStart();\n Log.i(\"LOG\",\"start B begin\");\n try {\n Thread.sleep(5000,0);\n } catch (InterruptedException e) {\n e.printStackTrace();\n }\n Log.i(\"LOG\",\"start B return\");\n}\n\n@Override\nprotected void onResume() {\n super.onResume();\n Log.i(\"LOG\",\"resume B begin\");\n try {\n Thread.sleep(5000,0);\n } catch (InterruptedException e) {\n e.printStackTrace();\n }\n Log.i(\"LOG\",\"resume B return\");\n}\n\n@Override\nprotected void onStop() {\n super.onStop();\n Log.i(\"LOG\",\"stop B begin\");\n try {\n Thread.sleep(3000,0);\n } catch (InterruptedException e) {\n e.printStackTrace();\n }\n Log.i(\"LOG\",\"stop B return\");\n}\n\n@Override\nprotected void onPause() {\n super.onPause();\n Log.i(\"LOG\", \"pause B begin\");\n try {\n Thread.sleep(3000,0);\n } catch (InterruptedException e) {\n e.printStackTrace();\n }\n Log.i(\"LOG\",\"pause B return\");\n}\n\n@Override\npublic void onWindowFocusChanged(boolean hasFocus) {\n super.onWindowFocusChanged(hasFocus);\n Log.i(\"LOG\",\"focus B begin\");\n try {\n Thread.sleep(5000,0);\n } catch (InterruptedException e) {\n e.printStackTrace();\n }\n Log.i(\"LOG\",\"focus B return\");\n}\n\n\nFrom above experiments, I came up with some conclusion and design strategies.\n\n\nDon't do too much things on Act B onResume & onFocus, or else users will see \"black screen\".\nFollowing by (1), do it in Act B \"onStart\" in instead. It's better to let user feel the delay with there's a view shown by previous Act A than seeing a \"black screen\".\nAsyncTask is definitely the solution. Show the view to user is top priority, data applied afterward.\n\n\n\n\nHowever, there's also a scenario like this: \nA chart application. User see the \"chart(layout)\" in the Activity, but the latest data hasn't filled in yet because the second thread is still fetching the data (maybe because it's too heavy). \n\nUser will see a blank chart at this point. To avoid this, we can then get the data prior to the creation of Activity. Either do this in the previous Activity or in the beginning of Application. To smooth the user experience.\n\n\n\nDid any one find this \"black screen\" pitfall as well? Or did I understand things incorrectly? Thank you very much!"

"Can't get .bat to run with PHP on WAMP localhost",

I can run the .bat file from the command line and it works fine, but nothing from within the PHP. \n\nThere's numerous other threads here asking how to run a .bat from PHP (ex: How do you run a .bat file from PHP?), and I've tried pretty much every technique I've read about online, and NOTHING WORKS. \n\nEx, I've tried \n\nexec('open.bat') (with the .bat in the same directory), shell_exec(), changing around the locations of files, paths, I really don't know what's up with it.

"Angular i18n - routing to locale client side - deploying subverted Angular index.html",
"Please critique this idea for setting up internationalized Angular project. This is Angular 11.\nI'm using the Angular I18N (https://angular.io/guide/i18n) method up to the point of deployment. From there, I essentially subvert the formal Angular way to what I think is a simpler set up.\nBackground:\nWe are using the Angular I18N to isolate strings, move them to xliff files, translate them, build localized copies of the application, and using LOCALE_ID to make sure the date, decimal, etc pipes appropriately localize (https://angular.io/api/core/LOCALE_ID).\nThe ng build --prod --localize builds N copies of the application with each one in a different folder. N is the number of locales specified in angular.json: /projects/.../i18n/locales plus the sourceLocale. E.g., if my source is 'en-US' and I have 'es' and 'fr' defined, the distribution has three folders 'en-US/', 'fr/', 'es/'.\nAn observation that will be important shortly is that each folder has many files which are nearly all identical. In our case, each folder has about 70 files totaling about 1 MB. Across folders, the files are identical except index.html and main.###.js. The index.html differs only by <html lang...> and <base href...>.\nEverything up to here follows the Angular documentation (https://angular.io/guide/i18n) and works fine.\nIf you deploy at this point, your application may be accessed by users by specifying their language of choice in the URL. .../your-app/en-US, .../your-app/es, etc. There are no files at root, so .../your-app displays nothing.\nAngular recommends configuring your server to redirect to the appropriate folder based on the http header value for accept language. That might work for some. We have a couple of issues with that: (1) access to server set up is limited, therefore it is preferable that we do the redirect client side. (2) The browser language is not necessarily the best choice. We want users to be able to set the language for the application. Until the user tells us, we will accept the browser language as a default. But the user override is important.\nMy first idea was to move all the files from /en-US into root. Now, there's a default application at .../your-app/. That can redirect based on language. However, to handle deep links would require a router imbroglio to be avoided.\nThe Plan\nMy current idea which seems to be working well is, after the build in the dist folder:\n\nMove all the files from en-US to root.\n\nMove es/main.###.js to ../main.es.###.js, fr/main.###.js to ../main.fr.###.js, etc.\n\nDelete all the subfolders. (Note how much smaller the distribution is now.)\n\nAlter index.html as follows:\n\n\n4a. Update <base href='/'>\n4b. Include a script which detects the user's preferred language.\n4c. In JS, create a script element, set the source to main.?lang?.###.js, body.appendChild(script).\n4d. Remove from the end of body <script src="main.###.js></script>\nThis works well. Deep links work fine. No routing to configure.\nAnyone see issues?\nObviously one is: "Angular might change things in the future that break this." But that's ALWAYS a problem."

"How do __builtin_ia32_unpcklps/hps and __builtin_ia32_movlhps/hlps work?",
"I am looking optimized ways to do matrix transpose on CPU only with a known cache set number and block size. I found that the Intel intrinsic functions contained a low-level transpose of a 4x4 matrix. As follows:\n\n#define _MM_TRANSPOSE4_PS(row0, row1, row2, row3) \\\ndo { \\\n __v4sf __r0 = (row0), __r1 = (row1), __r2 = (row2), __r3 = (row3); \\\n __v4sf __t0 = __builtin_ia32_unpcklps (__r0, __r1); \\\n __v4sf __t1 = __builtin_ia32_unpcklps (__r2, __r3); \\\n __v4sf __t2 = __builtin_ia32_unpckhps (__r0, __r1); \\\n __v4sf __t3 = __builtin_ia32_unpckhps (__r2, __r3); \\\n (row0) = __builtin_ia32_movlhps (__t0, __t1); \\\n (row1) = __builtin_ia32_movhlps (__t1, __t0); \\\n (row2) = __builtin_ia32_movlhps (__t2, __t3); \\\n (row3) = __builtin_ia32_movhlps (__t3, __t2); \\\n} while (0)\n\n\n\nThe functions its using are built-in GCC compiler functions which use the UNPCKHPS/LPS and MOVLHPS/HLPS x86 assembly commands. That I understand and I roughly understand how those commands would work together to transpose the 4 rows.\n\nHowever, I wanted to test these functions and so I copy this into my code and edited it slightly.\n\nI found that simiply subsituting the function into the arguments with out using a temporary varible broke the function. Here is an example of that:\n\n#define _MM_TRANSPOSE4_PS(row0, row1, row2, row3) \\\ndo { \\\n __v4sf __r0 = (row0), __r1 = (row1), __r2 = (row2), __r3 = (row3); \\\n __v4sf __t1 = __builtin_ia32_unpcklps (__r2, __r3); \\\n __v4sf __t2 = __builtin_ia32_unpckhps (__r0, __r1); \\\n __v4sf __t3 = __builtin_ia32_unpckhps (__r2, __r3); \\\n (row0) = __builtin_ia32_movlhps (__builtin_ia32_unpcklps (__r0, __r1), __t1); \\\n (row1) = __builtin_ia32_movhlps (__t1, __builtin_ia32_unpcklps (__r0, __r1)); \\\n (row2) = __builtin_ia32_movlhps (__t2, __t3); \\\n (row3) = __builtin_ia32_movhlps (__t3, __t2); \\\n} while (0)\n\n\n\nDoes anyone know why this would happen? Normally, if you change the order of function calls (assuming that they aren't operating on the same pointer) cannot effect execution."

Args could be e.g.: \n\n$mountpath = 'd:\\autoupdating' \n$package = 'D:\\updates\\whatever.cab' \n$dismcommands = \"/image:$mountpath /add-package /packagepath:$package \n\nSolution:\n\nPoSh or DISM has heavy problems when getting $dismcommands like I wanted it. DISM does not recognize the string as available commands. You can bypass this easiely by going\nDISM.exe \"/image:$mountpath /add-package /packagepath:$package\" which works without a problem.\nFurthermore you need to modify the $env:Path variable to target C:\\Program Files (x86)\\Windows Kits\\10\\Assessment and Deployment Kit\\Deployment Tools\\amd64\\DISM\\.

I've got a table set up that generates rows dynamically from a database using ng-repeat, with span and input elements that hide/show based on editing/not editing the cell (imagine microsoft excel).\n\n<tr>\n <th class=\"row_head\">Row Title</th>\n <td ng-click=\"edit = true\" ng-repeat=\"item1 in JSONobject | orderBy: '_id'\" >\n <span ng-hide=\"edit\">{{ item1.key.value1 }}</span>\n <input ng-show=\"edit\" class=\"editing-cell\" ng-model=\"item1.key.value1\" ng-blur=\"edit = false; \" ng-enter=\"saveData(item1._id, item1.key); edit = false\" type=\"text\" />\n </td>\n</tr>\n\n<tr>\n <th class=\"row_head\">Row Title</th>\n <td ng-click=\"edit = true\" ng-repeat=\"item2 in JSONobject | orderBy: '_id'\" >\n <span ng-hide=\"edit\">{{ item2.key.value2 }}</span>\n <input ng-show=\"edit\" class=\"editing-cell\" ng-model=\"item2.key.value2\" ng-blur=\"edit = false; \" ng-enter=\"saveData(item2._id, item2.key); edit = false\" type=\"text\" />\n </td>\n</tr>\n\n\nand so on. \n\nI want to set it so on blur (data not saved) the cell turns red, and alternatively on save - turns green.\n\nThe issue i'm running into with ngClass is if i just go with:\n\nng-class=\"{'saved': saved, 'notSaved': notSaved}\"\n\n\nIt changes the background color of EVERY cell, rather than just the cell edited. \n\nI do not have this issue with ng-hide and ng-show, even though they appear to be a similar scenario with changing the boolean value of 'edit'. They still stick to their specific cell.\n\nAny help would be appreciated."

Given the fact that tasks can be untied, they can in theory execute within a different worker thread, therefore allowing an OpenMP thread access to the private memory of another."
