问题 What happens when the clock of the computer running python (Windows or Linux) gets automatically changed and a call time.time() ? I've read that the value of time.time() will be smaller when the clock is changed manually to some value in the past. 回答1: time.time() docs state: Return the time in seconds since the epoch as a floating point number. The particular epoch referred to here is the Unix epoch, which is Midnight, Jan 1st 1970 UTC . Since it is always based on UTC, it will not be

问题 I am using C++ and trying to output a file to a specific place, a folder with a specified name in the same directory as the executable. Couldn't find a great resource on an easy way to do this but I know it must be possible. My example. I am saving a log file and instead of having it save to the same directory as the executable, it saves to /logs/ Thank you for your time! Edit: I used mkdir to create a folder but how do I output to that folder. Is mkdir even a good thing to be using? I want

问题 i've got problem with saving texture2d to file, it always gives me black image. Here is code: HRESULT hr = SwapChain->GetBuffer( 0, __uuidof( ID3D11Texture2D ), reinterpret_cast< void** >( &g_pSurface ) ); if( g_pSurface ) { ID3D11Texture2D* pNewTexture = NULL; D3D11_TEXTURE2D_DESC description; g_pSurface->GetDesc( &description ); description.BindFlags = 0; description.CPUAccessFlags = D3D11_CPU_ACCESS_READ | D3D11_CPU_ACCESS_WRITE; description.Usage = D3D11_USAGE_STAGING; HRESULT hr =

问题 Is it possible to use the Matlab save command inside a function to store workspace variables? Consider following scenario: I've got a bunch of variables in the Matlab workspace and want all that are beginning with "a" and "b" in a .mat file. Of course this works: save('test.mat','a*','b*') but i want to have a variable filename. The function i wrote: function save_with_name(name) save(name,'a*','b*') does not work, because save_with_name doesn't see the workspace variables. Is there a

问题 Ember Data is moving fast from version to version and the method for saving data has been changing along with it. Right now with version 1.0.0-beta.8.2a68c63a the proper method is to update a record and then do a record.save() to trigger a PUT request back to the server. With my current app I'm updating multiple records at once and that could involve 50+ PUT ajax requests back to the server. We're concerned about performance and efficiency issues and haven't found any documentation for doing

问题 I have a strange problem. I have never had it before. When I try to save int value to my SharedPreference and then restore in other Activity. Value is always 0 even if I save there other value (for example: 1); private String Number; private String Profile; and then saving values (in this case "1") to SharedPreferences in first Activity: SharedPreferences a = FirstActivity.this.getSharedPreferences("a", MODE_PRIVATE); SharedPreferences.Editor prefsEditorProfiles = a.edit();

问题 I'm developping an application in java that regulary saves objects onto the hard disk using this simple method: public void save(String filename) { try { FileOutputStream fos = new FileOutputStream(filename); GZIPOutputStream gzos = new GZIPOutputStream(fos); ObjectOutputStream out = new ObjectOutputStream(gzos); out.writeObject(this); out.flush(); out.close(); } catch (IOException e) { e.printStackTrace(); } } The object is an instance of sebbot.learning.DirectPolicySearch class. The problem

问题 I'm writing a Cookbook application, and I've not been able to find anything on how to save the data of a class I've created (the Recipe class). The only way I've seen would be to possibly save the contents of this class as a whole without individually saving every element of the class for each object by making this method for my Recipe class: -(void) writeToFile:(NSString *)file atomically:(BOOL)atomic{ } But I have absolutely no idea how I'd go about implementing this to save this object to

问题 From the ember docs its clear you should be able to save a dirty model var m = App.MyModel.find(10) ; ... m.set("firstName", "John") ; m.get("isDirty") ; // --> true Now, I don't know how to save, things like m.save() ; App.MyModel.save(m) ; //etc do not work. Any suggestions ? CHeers 回答1: EDIT: This is now out of date with Ember Data 1.0 beta and onwards, please refer to Bart's answer If you are using Ember-Data, you need to call commit() on the model's transaction. m.get('transaction')
