  • How to determine cpu, ram needed for rails app?

    - by Ben
    What is the most accurate way to determine the amount of cpu speed and ram needed to run my rails app? I believe there are stress testing tools like Tsung, but how do I determine, for example, that I need X more ram, or X more CPU? I would like to find some way to roughly gauge the performance needs of my application so I can anticipate future needs. I think this data will also be useful for me to decide whether to upgrade one machine, or get another dedicated machine and put all the databases on that one. Essentially, I am concerned about scaling issues, and how to anticipate them. Thanks in advance for the help!

  • Server Benchmarking: What tools to use with my real-world test data

    - by mdemmitt
    I want to benchmark a new server using historical HTTP-request data. I have a textfile that contains one day's worth of real historical requests to a production server. What is the best tool for sending that list of requests on the server I'm testing? The tool I use should be able to configure the following: Number of threads making the requests Number of requests/second sent A list of request URLs to use when making the requests. Apache Bench seems like a close fit. However, Bench does not seem to be able to take in a list of request URLs as a parameter. What would you recommend?

  • check whether mmap'ed address is correct

    - by reddot
    I'm writing a high-loaded daemon that should be run on the FreeBSD 8.0 and on Linux as well. The main purpose of daemon is to pass files that are requested by their identifier. Identifier is converted into local filename/file size via request to db. And then I use sequential mmap() calls to pass file blocks with send(). However sometimes there are mismatch of filesize in db and filesize on filesystem (realsize < size in db). In this situation I've sent all real data blocks and when next data block is mapped -- mmap returns no errors, just usual address (I've checked errno variable also, it's equal to zero after mmap). And when daemon tries to send this block it gets Segmentation Fault. (This behaviour is guarantedly issued on FreeBSD 8.0 amd64) I was using safe check before open to ensure size with stat() call. However real life shows to me that segfault still can be raised in rare situtaions. So, my question is there a way to check whether pointer is accessible before dereferencing it? When I've opened core in gdb, gdb says that given address is out of bound. Probably there is another solution somebody can propose.

  • How can I dynamically load the correct sprite from a sprite sheet?

    - by Leonard Challis
    I am making a simple card game in unity. The game is based on a standard 52-card pack, with identical backs for unique faces. In my particular game different cards are worth different values and have various special abilities. The game will have 52 cards on the table (on the draw position or in the face-down deck or in someone's hand) at all times, so this number won't change. I thought that making a Card prefab and instantiating 52 of these manually would be a bad idea. Even doing it in code, I thought, would be a bit OTT, and that I should just instantiate visual cards when they are face-up to the player. I have a sprite sheet of the 52 cards and the back, which is imported as a Sprite in multiple mode, sliced in to a grid containing all the cards needed to play the game. The problem I now face is that, through my GameController script I want to generate a shuffled pack of cards, deal some to each player and then show those cards to a player. However, I am not sure of the best way, or even if it's possible, to do this dynamically with the sprite sheets as they are. For instance if I have the following: private CardRank rank; private CardSuite suite; private void Start() { this.rank = CardRank.Ace; this.suite = CardSuite.Spades; } This class would be instantiated by the game manager. I would have 52 of these in code. Whenever I have to visually show a card in the scene, I would use a card prefab, which is essentially a game object with a SpriteRenderer on it. I would need to dynamically load the correct sprite for this object from the spritesheet. The sliced sprites from the sprite sheet actually have names in the format AS (Ace of Spades), 7H (Seven of Hearts), etc - though this was a manual thing I did myself of course. I have also tried various alternative solutions, including creating animations, having separate sprites not in a spritesheet and having an array of available sprites in an array with a specific index for each card, but none seem as elegant as trying to load the correct sprite at runtime, as I'm trying to. So, how do I load a specific sprite from a spritesheet at runtime? I'm open to suggestions, even those that make me think differently about how to approach the problem.

  • Android Loading Screen: How do I use a stack to load elements?

    - by tom_mai78101
    I have some problems with figuring out what value I should put in the function: int value_needed_to_figure_out = X; ProgressBar.incrementProgressBy(value_needed_to_figure_out); I've been researching about loading screens and how to use them. Some examples I've seen have implemented Thread.sleep() in a Handler.post(new Runnable()) function. To me, I got most of that concept of using the Handler to update the ProgressBar, while pretending to do some heavy crunching work. So, I kept looking. I have read this thread here: How do I load chunks of data from an assest manager during a loading screen? It said that I can try using a stack it needs to load, and adding a size counter as I add elements to the stack. What does it mean? This is the part where I'm totally stumped. If anyone would provide some hints, I'll gladly appreciate it. Thanks in advance.

  • SecurityException from Activator.CreateInstance(), How to grant permissons to Assembly?

    - by user365164
    I have been loading an assembly via Assembly.LoadFrom(@"path"); and then doing Type t = asm.GetType("Test.Test"); test = Activator.CreateInstance(t, new Object[] { ... }); and it was working fine, but now I moved the dll I am getting the following System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.Security.SecurityException: Request for the permission of type 'System.Security.Permissons.SecurityPermission, etc .. For the sake of brevity it seems the demand was for an PermissionSet that allowed ControlAppDomain and it's not getting it. My question is how can I create this permissionset and pass it to the instance or assembly? I've been googling for hours to no avail.

  • How to show jQuery is working/waiting/loading ?

    - by Kim
    How do I show a loading picture and/or message to the user ? If possible, would I like to know how to make it full screen with grey-dimmed background. Kinda like when viewing the large picture from some galleries (sorry, no example link). Currently do I add a CSS class which has the image and other formating, but its not working for some reason. Results from the search do get inserted into the div. HTML <div id="searchresults"></div> CSS div.loading { background-image: url('../img/loading.gif'); background-position: center; width: 80px; height: 80px; } JS $(document).ready(function(){ $('#searchform').submit(function(){ $('#searchresults').addClass('loading'); $.post('search.php', $('#'+this.id).serialize(),function(result){ $('#searchresults').html(result); }); $('#searchresults').removeClass('loading'); return false; }); });

  • What is the best way to call a method right AFTER a form loads?

    - by Jordan S
    I have a C# windows forms application. The way I currently have it set up, when Form1_Load() runs it checks for recovered unsaved data and if it finds some it prompts the user if they want to open that data. When the program runs it works alright but the message box is shown right away and the main program form (Form1) does not show until after the user clicks yes or no. I would like the Form1 to pop up first and then the message box prompt. Now to get around this problem before I have created a timer in my Form, started the timer in the Form1_Load() method, and then performed the check and user prompt in the first Timer Tick Event. This technique solves the problem but is seems like there might be a better way. Do you guys have any better ideas? Edit: I think I have also used a background worker to do something similar. It just seems kinda goofy to go through all the trouble of invoking the method to back to the form thread and all that crap just to have it delayed a couple milliseconds!

  • Variable reference problem when loading an object from a file in Java

    - by Snail
    I have a problem with the reference of a variable when loading a saved serialized object from a data file. All the variables referencing to the same object doesn't seem to update on the change. I've made a code snipped below that illustrates the problem. Tournament test1 = new Tournament(); Tournament test2 = test1; try { FileInputStream fis = new FileInputStream("test.out"); ObjectInputStream in = new ObjectInputStream(fis); test1 = (Tournament) in.readObject(); in.close(); } catch (IOException ex){ Logger.getLogger(Frame.class.getName()).log(Level.SEVERE, null, ex); } catch (ClassNotFoundException ex){ Logger.getLogger(Frame.class.getName()).log(Level.SEVERE, null, ex); } System.out.println("test1: " + test1); System.out.println("test2: " + test2); After this code is ran test1 and test2 doesn't reference to the same object anymore. To my knowledge they should do that since in the declaration of test2 makes it a reference to test1. When test1 is updated test2 should reflect the change and return the new object when called in the code. Am I missing something essential here or have I been misstaught about how the variable references in Java works?

  • NSUserDefaults: Saved Number Always 0, iPhone

    - by Stumf
    Hello all, I have looked at other answers and the docs. Maybe I am missing something, or maybe I have another issue. I am trying to save a number on exiting the app, and then when the app is loaded I want to check if this value exists and take action accordingly. This is what I have tried: To save on exiting: - (void)applicationWillTerminate: (UIApplication *) application { double save = [label.text doubleValue]; [[NSUserDefaults standardUserDefaults] setDouble: save forKey: @"savedNumber"]; [[NSUserDefaults standardUserDefaults] synchronize]; } To check: - (IBAction)buttonclickSkip{ double save = [[NSUserDefaults standardUserDefaults] doubleForKey: @"savedNumber"]; if (save == 0) { [self performSelector:@selector(displayAlert) withObject:nil]; test.enabled = YES; test.alpha = 1.0; skip.enabled = NO; skip.alpha = 0.0; } else { label.text = [NSString stringWithFormat:@"%.1f %%", save]; } } The problem is I always get my alert message displayed, the saved value is not put into the label so somehow == 0 is always true. If it makes any difference I am testing this on the iPhone simulator. Many thanks, Stu

  • Bulkloading schema less entities on Google App Engine

    - by Rahul
    The new bulkloader added into SDK 1.3.4 works great for models that have a schema. For models inheriting db.Expando (or loosely defined schemas) i would like to understand what i would have to do to bulk upload them. I defined a custom connector, that implemented the ConnectorInterface and converted my data to the python dict required. How can i use this dict to define entities that get uploaded to the data store ? In the documentation there seems to be a post_import_function that can be used to return the entities that get uploaded. Is there an example on how this function is used ?

  • SQL Server 2008 BULK INSERT causes more reads than writes. Why?

    I've huge a table (a few billion rows) with a clustered index and two non-clustered indices. A BULK INSERT operation produces 112000 reads and only 383 writes (duration 19948ms).

  • Asp.net Site on GoDaddy Loads Slowly

    - by Randy
    I just published a very small site to GoDaddy that I programmed in Microsoft Visual Web Developer 2008. The site only contains 6 sheets, none of which are data intensive. Each has a few small images that serve mostly to navigate to the other sheets. There is no data, no SQL, nothing like that. There is one master page that governs the page layout for all of the pages. Everything works fine, for the most part. I am posting because the site loads quite slowly, particularly considering how little content is being loaded. Can anybody give me any advice about what I should look at to speed this thing up a little bit? Is this an asp.net issue? Use of master pages? Godaddy? Something else? I'm a newbie, so speak slowly. Thanks.

  • How can I detect 'any' ajax request being completed using jQuery?

    - by Brian Scott
    I have a page where I can insert some javascript / jquery to manipulate the output. I don't have any other control over the page markup etc. I need to add an extra element via jquery after each present on the page. The issue is that the elements are generated via an asynchronous call on the existing page which occurs after $(document).ready is complete. Essentially, I need a way of calling my jquery after the page has loaded and the subsequent ajax calls have completed. Is there a way to detect the completion of any ajax call on the page and then call my own custom function to insert the additional elements after the newly created s ?

  • A GUID as the MySQL table's Primary Key or as a separate column

    - by Ben
    I have a multi-process program that performs, in a 2 hour period, 5-10 million inserts to a 34GB table within a single Master/Slave MySQL setup (plus an equal number of reads in that period). The table in question has only 5 fields and 3 (single field) indexes. The primary key is auto-incrementing. I am far from a DBA, but the database appears to be crippled during this two hour period. So, I have a couple of general questions. 1) How much bang will I get out of batching these writes into units of 10? Currently, I am writing each insert serially because, after writing, I immediately need to know, in my program, the resulting primary key of each insert. The PK is the only unique field presently and approximating the order of insertion with something like a Datetime field or a multi-column value is not acceptable. If I perform a bulk insert, I won't know these IDs, which is a problem. So, I've been thinking about turning the auto-increment primary key into a GUID and enforcing uniqueness. I've also been kicking around the idea of creating a new column just for the purposes of the GUID. I don't really see the what that achieves though, that the PK approach doesn't already offer. As far as I can tell, the big downside to making the PK a randomly generated number is that the index would take a long time to update on each insert (since insertion order would not be sequential). Is that an acceptable approach for a table that is taking this number of writes? Thanks, Ben
