问题 There's a difference between RAM memory and internal flash memory right? I can get RAM memory by: cat /proc/meminfo However, I am not sure how to get Flash memory information. I think I know how to get available memory: ActivityManager activityManager = (ActivityManager).getSystemService(Context.ACTIVITY_SERVICE); MemoryInfo memoryInfo = new ActivityManager.MemoryInfo(); activityManager.getMemoryInfo(memoryInfo); memoryInfo.availMem; Does this give available internal Flash memory? How about

问题 In Spring, the two following statements are, if I'm not mistaken, identical: @RequestParam("type") String type @RequestParam String type How can spring know the variable name of 'type' (second version). I was under the impression that this information was removed from the class files unless compiled with the -g flag (include debug information). 回答1: The short version of this is that apparently the parameter names are being compiled in, if they weren't, you'd get an exception indicating that

问题 I'm trying to understand the internal access modifier in C#. I can't seem to understand what an assembly is exactly, and what part of my program is held inside that assembly. I was trying to make it so that a variable is accessibly only by objects within the following namespace: namespace Engine.Entity The variable in question is defined in a class inside of that namespace, so I assumed if I made it internal, only objects inside of that namespace have access to it. I am seeing assemblies and

问题 I've a very basic question about spark. I usually run spark jobs using 50 cores. While viewing the job progress, most of the times it shows 50 processes running in parallel (as it is supposed to do), but sometimes it shows only 2 or 4 spark processes running in parallel. Like this: [Stage 8:================================> (297 + 2) / 500] The RDD's being processed are repartitioned on more than 100 partitions. So that shouldn't be an issue. I have an observations though. I've seen the

问题 This question already has answers here : What's the difference between a public constructor in an internal class and an internal constructor? (5 answers) Closed 6 years ago . I've seen some C# code that declares a class with an internal modifier, with a public constructor: internal class SomeClass { public SomeClass() { } } What is the point of having a public constructor, if the visibility of the entire class is internal, thus it can be seen only inside the defining assembly? Also, does this

问题 It seems really inefficient that in PHP, when an array is assigned by value all of its internal elements are recursively copied to the new variable. Is this what really happens internally? 回答1: No, the internally array is not deep-copied on assignment. Consider the following snippet: $a = array(111, 222, 333); $b = $a; $b[0] = 999; If a picture is worth a thousand words, then here is what happens internally when arrays are assigned and then their array elements are modified: 来源： https:/

问题 This question already has answers here : Which maximum does Python pick in the case of a tie? (5 answers) Closed 6 years ago . I need to know how the min function of python works if there are more than one item in a list which are minimum. Which one takes min? Say A = [5, 3, 1, 4, 1]. Now if I say A.remove(min(A)) which one will be removed? The first 1 or the second 1? 回答1: In this case it will remove the first one. It's more about the behavior of the list.remove function rather than the min

问题 I have two servers setup on Amazon AWS. One server is running PHP and the other has MySQL. I can connect to the MySQL database through my terminal and MySQL Query Browser. I am trying to get a connection between the PHP and MySQL servers. Here is the PHP Code that I am using (works for "localhost" databases) $dbbase = 'mydb'; $dbuser = 'myuser'; // Your MySQL username $dbpass = 'mypassword'; // ...and password $dbhost = 'localhost:3306'; // Internal IP for MYSQL Server // connect to database

问题 I create only a table from code but inside still empty. I instead insert data by pull a file out and insert by SQLite Browser when run the emulator then, put it back to the data/data/package_name/file.db with this solution, after run the program I can see the list of information in Emulator. But moving the application on a real device, I cannot see any list of information on a real device. How should I do? Because my application just provide the data to user, so user has no need to add or

问题 I'm trying to write a file in my app's android internal storage space. After so many trials, I was finally successful using this method Writing/Reading Files to/from Android phone's internal memory . However, when I go to data/data/package_name/files, I cannot find my package, and cannot even find the MyFile.txt. In fact, I can't find them anywhere in internal memory. Why is that? 来源： https://stackoverflow.com/questions/30000148/android-file-on-internal-storage-not-found
