android - How much is too much memory allocation in NDK? -

-

NDK download page notes, "The best good candidates for NDK are self-contained, CPU-intensive campaigns that don 'A' allocate a lot of memory, such as signal processing, physics simulation, and so on."

I came from C background and used to use NDK was excited to work most of my OpenGL ES functions physics, animation of the meridian, etc. Related native functions ... I know I'm up a little running that I have the original code and I am wondering whether I could make the mistake. I have not had any problem in testing at this point, but I am curious if I have problems in the future. For example, I have defined the game structure (as seen in San-Anjelus example). I'm dynamically loading vertical information for objects (just what is needed for an active game area), so vertical, normal, textured coordinates, index and texture are a bit of memory allocation for graphic data ... just the name needed I take precautions about the allocation between the areas of the game.

Do I want to protect some caps in the size of the array or should I move forward to move forward?

Since applications using NDK should behave like those developing by using SDK , I think the best guidance for the use of the appropriate heap is the comment. 

  / ** * Existing copy-device memory class return to current device * It gives you an idea that How hard is the memory limit on your system That's why you let the overall system do the best job. * The returned value is in megabytes; Baseline Android Memory Class * 16 (which is the Java Hepap range of those devices); Some memory devices with more memory can return 24 or more numbers. * / Public int getMemoryClass () {return staticGetMemoryClass (); } / ** @Hide * / static public int static gate memory class () {// literally in the brain - just take it from the configured / vm hep size, and assume that it is in megabyte and thus " M "ends with string vmHeapSize = SystemProperties.get (" Dalvik.vm.heapsize "," 16m "); Return integer Parascent (vmHeapSize.substring (0, vmHeapSize.length () - 1)); }

The code that sets the size of the pile for the Dual VM is in. And using the function, give an example to define a border for the pile allocation in the native code is. 

  Structio (Hepsize Opsby, "-XMX"); Properties_gate ("Dalvik. VM. Hepases", Hepsz's Opsf + 4, "16m"); // LOGI ("Size Size:% s", Hepesz Opsbuff); Opt.optionString = heapsizeOptsBuf; MOptions.add (optional); The default value of

16m is potentially important because neither does I have two Android phones dalvik.vm.heapsize default property Set by form

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa...

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])
