if can catch more specific exception prevent clr doing work , benefit performance wise ? if know might socket exception not care handling differently other exception better still have more specific catch ? working on microframework small improvements in performance , resources worth asking about. catch (system.net.sockets.socketexception netex) { } catch (exception ex) { } i not think in terms of performance. from code correctness perspective: should catch specific exception can. when catch exception exception handler swallow any exception if not prepared handle it. imagine argumentnullexception thrown. catch block swallow , cause confusion. if prepared handle socketexception catch that. if less performant it. code correctness not sacrifice such miniscule performance gain* * or no performance gain @ - almost there zero execution time performance implication @ all. did benchmark on computer , performanc...

i trying load in json file. update , write back. here attempt @ getting error: typeerror: dump() takes @ least 2 arguments (1 given) with open('employees.json') data_file: employees = json.load(data_file) data_file.close employees['employees'].append({ "id": "2", "name": "rob croft", "key": "0003837852"}) open('employees.json', 'w') data_file: json.dump(employees) data_file.close you forgot pass in file object: json.dump(employees, data_file) since using file object context manager with statement, not need manually close file. , using data_file.close entirely redundant since not calling file.close() method.

i don't understand source_group command in cmakelists.txt. when works: file(glob input_head keyboard.h mouse.h) source_group("header files\\input" files ${input_head}) but isn't working: file(glob shaders ../shaders/*.txt) source_group("source files\\shaders" files ${shaders}) any suggestions on how solve this? (i have read documentation command, don't understand whythis doesn't work) you need use files in actual target. example must used in add_library or add_executable statement, in folder within project. also, use ''/'' rather \\ separator. may want use set_property(global property use_folders on) have predefined cmake projects go own solution folder.
