  • What is the best way to exploit multicores when making multithread games?

    - by Keeper
    Many people suggest to write a program, and then start optimizing it. But I think that when it's coming to multithreading with multicore, a little think ahead is required. I've read about using threads, and experienced it myself during some courses at the university (still a student). The big question is simple, but a bit abstract: What thread related steps in game design do I need to take, before implementation? Now trying to be more specific. Let's say, as an example, that I'm making a small board game (like Monopoly) that I want to be multithreaded. My goal Is that this multithreaded game will exploit the best of the multicore system, lets say 4-6 cores (like in i7 processors). My answer to this question at the moment is, one thread for each of these four basic components: GUI User Input / Output AI (computer rival) Other game related calculations (like shortest path from A to B, or level up status change) I'm not an expert (yet!), and I'm sure there are better answers out there. Any suggestion, answer, different approach will be helpful. Some thoughts: Maybe splitting the main database is a good way.. (or total disaster.. )

  • Separating my VPN connection from my internet access

    - by Christi
    Background: Home PC is Windows XP and using Cisco VPN client; home internet connection is fast (20MB) office VPN router is Cisco RV110W; work internet connection is slow (1.5MB) With VPN connected, my home PC internet surfing is very slow. I looked this up in Google and found talk about splitting, tunneling, routing tables, etc., but I'm not sure what/how to do it. Basically, I would like a persistent VPN connection with the office resources, and at the same time, utilize my home high speed internet connection to access the internet. Can someone help me the steps as how-to?

  • Unity gizmos vs. referenced game objects

    - by DuckMaestro
    I'm designing a Unity script that I intend to be highly reusable and as easy as possible to setup within the editor. To this end, a number of properties of this script really need some kind of visual representation on screen. It is an unresolved question to me whether the design of the script should require references to placeholder game objects, OR just Vector3's and float's that have associated gizmos drawn for them. Normally a gizmo would be a natural choice, except that Unity gizmos are not directly manipulable (as far as I can tell). Because of this shortcoming I'm having to consider whether depending on references to placeholder game objects is a more designer-friendly approach ultimately, in spite of the extra setup required, and that it might be counter-intuitive when the placeholder game objects disappear at run-time (which my script would do). Is there a community standard or preference here in this case? Can a Unity-experienced game programmer / designer speak to which approach they feel is more intuitive or more convenient to setup, when using a 3rd party script? Or is this just splitting hairs as long as I ship an example prefab with my script?

  • Split a table in Word without losing row title

    - by Shane Hsu
    Word has the feature to repeat title row of a table when a table is so long that it spans a bunch of pages. I need to categorize my data into several pages, and I did that by splitting the table and insert page split to put them all in a page of itself. So now I got several page of data, but only the first page has title row. Is there anyway else to do this beside manually adding the title row to all the other pages? Original data: _________________ | Cat. Data | | 1 * | | 1 * | | 1 * | | 1 * | | 1 * | | 1 * | | 2 * | | 2 * | | 2 * | | 2 * | | 3 * | |___3______*______| And then turn it into: _________________ | Cat. Data | | 1 * | | 1 * | | 1 * | | 1 * | | 1 * | |___1______*______| Next page _________________ | Cat. Data | | 2 * | | 2 * | | 2 * | |___2______*______| Next Page _________________ | Cat.

  • Excel: How do I copy hyperlink address from one column of text to another column with different text?

    - by OfficeLackey
    I have a spreadsheet where column A displays names in a certain format. There are 200-odd names and each has a different hyperlink (which links to that person's web page). I want to reformat the name order so it is "Surname, Name" rather than "Name Surname" and retain the hyperlink in the newly formatted column. I have achieved "Surname, Name" easily by splitting the names into two columns (using LEFT and RIGHT formulae) - forename and surname - then I have a new column with a formula to return "Surname, Name." However, the hyperlinks are not in that new column and I need them. I don't want to do this manually, for obvious reasons. I cannot find a way of copying just hyperlinks from column A without copying the text from column A. So, effectively, what I need is some sort of macro to take, for example, the hyperlink from A2 and copy it to H2, with H2 still retaining the updated ordering of name. I don't have the knowledge to write this myself, so would appreciate solutions.

  • Advice on whether to use scripting, run time compile or something else

    - by Gaz83
    I work in the prodution area at my works and I design and create the software to run our automated test equipment. Everytime I get involved with a new machine I end up with a different and (hopefully) better design. Anyway I have come to the point where I feel I need to start standardization all the machines with the same program. I see a problem when it comes to applying updates as at the moment the test procedures are hard coded into the program at each station. I neeed to be able to update the core program without affecting the testing section. The way I see it that this will mean splitting the program into 2 sections. Main UI - This is the core that talks to everything on the machine such as cameras, sensors, printer etc and is a standalone application. Test Procedure - This is the steps that is executeted everytime the machine runs through a test. The main UI will load the test procedure and execute when ever a test is required. My question is what is the best approach to this in terms of having an application load a file and execute the code with in? Take into account that the code in the test procedure will need access to public methods on the UI/core system to communicate to sensors etc. I have heard about MS Roslyn and had a quick look, would this solve my issue?

  • How to quickly search through a very large list of strings / records on a database

    - by Giorgio
    I have the following problem: I have a database containing more than 2 million records. Each record has a string field X and I want to display a list of records for which field X contains a certain string. Each record is about 500 bytes in size. To make it more concrete: in the GUI of my application I have a text field where I can enter a string. Above the text field I have a table displaying the (first N, e.g. 100) records that match the string in the text field. When I type or delete one character in the text field, the table content must be updated on the fly. I wonder if there is an efficient way of doing this using appropriate index structures and / or caching. As explained above, I only want to display the first N items that match the query. Therefore, for N small enough, it should not be a big issue loading the matching items from the database. Besides, caching items in main memory can make retrieval faster. I think the main problem is how to find the matching items quickly, given the pattern string. Can I rely on some DBMS facilities, or do I have to build some in-memory index myself? Any ideas? EDIT I have run a first experiment. I have split the records into different text files (at most 200 records per file) and put the files in different directories (I used the content of one data field to determine the directory tree). I end up with about 50000 files in about 40000 directories. I have then run Lucene to index the files. Searching for a string with the Lucene demo program is pretty fast. Splitting and indexing took a few minutes: this is totally acceptable for me because it is a static data set that I want to query. The next step is to integrate Lucene in the main program and use the hits returned by Lucene to load the relevant records into main memory.

  • In C++ Good reasons for NOT using symmetrical memory management (i.e. new and delete)

    - by Jim G
    I try to learn C++ and programming in general. Currently I am studying open source with help of UML. Learning is my hobby and great one too. My understanding of memory allocation in C++ is that it should be symmetrical. A class is responsible for its resources. If memory is allocated using new it should be returned using delete in the same class. It is like in a library you, the class, are responsibility for the books you have borrowed and you return them then you are done. This, in my mind, makes sense. It makes memory management more manageable so to speak. So far so good. The problem is that this is not how it works in the real world. In Qt for instance, you create QtObjects with new and then hand over the ownership of the object to Qt. In other words you create QtObjects and Qt destroys them for you. Thus unsymmetrical memory management. Obviously the people behind Qt must have a good reason for doing this. It must be beneficial in some kind of way, My questions is: What is the problem with Bjarne Stroustrups idea about a symmetrical memory management contained within a class? What do you gain by splitting new and delete so you create an object and destroy it in different classes like you do in Qt. Is it common to split new and delete and why in such case, in other projects not involving Qt? Thanks for any help shedding light on this mystery!

  • HP MSA 1000 SAN: Can I use 1 array/shelf?

    - by CC
    Hi all, I'm planning some expansion on an HP MSA1000 SAN. My boss says that we need to have two separate arrays on the new enclosure, one for Bays 1-7, the other for Bays 8-14. Is there any reason that we need to do this? My plan was to have the entire expansion shelf be 1 array, then create RAID 6 logical drives from that. I don't understand what splitting drives into separate arrays gain us. We don't have dual controllers, so there's no benefit there. Thanks, CC

  • is it possible to access/write database ms access 2003 .mdb at the same time?

    - by tintincute
    hi i have a problem, i have a user who created a database using ms access 2003 the problem is, if he's opening the db and made some changes, the other user can open the db but they can't work on it. but if he's exited the program, then the user can make some changes. i would like to know if its possible; that they can work at the same time when they open the database? Thanks I attached a .jpg here to see the program: www.freeimagehosting.net/image.php?ed11af4cc5.jpg additional jpg: http://www.freeimagehosting.net/image.php?3c60d8e046.jpg additional question: I tried to do the "Splitting of Database" here and after I clicked on Split I got an error: "The database engine couldn't lock the table, because it is already in use by another person or process"... what does that mean?

  • How does storage spaces decide where to put my files?

    - by George Duckett
    With Windows 8 Storage Spaces, you can lump many hard disks of varying types, speeds and sizes together to use as a single storage space / logical drive. How does Windows decide what to place where? For example will it move files about depending on frequency of access? Maybe splitting files frequently accessed together between hard disks etc. What does it optimize for? Speed, reliability, etc? If the above is asking too much, can I easily see where the files are physically (on which physical disk)?

  • Create a Texture2D from larger image

    - by Dialock
    I am having trouble with the basic logic of this solution: Xna: Splitting one large texture into an array of smaller textures in respect to my specific problem (specifically, I'm looking at the second answer.) How can I use my source rectangle that I already use for drawing to create a new Texture2D? spriteBatch.Draw(CurrentMap.CollisionSet, currentMap.CellScreenRectangle(x, y), CurrentMap.TileSourceRectangle(currentMap.MapCells[x, y].TileDepths[4]), Color.FromNonPremultiplied(0,0,0, 45), 0.0f, Vector2.Zero, SpriteEffects.None, 0.91f); I know I want a method that I started so: //In Update Method of say the player's character. Texture2D CollisionTexture = ExtractTexture(MapManager.CurrentMap.CollisionSet, MapManager.TileWidth, MapManager.TileHeight); // In MapManager Class who knows everything about tiles that make up a level. public Texture2D ExtractTexture(Texture2D original, int partWidth, int partheight, MapTile mapCell) { var dataPerPart = partWidth * partheight; Color[] originalPixelData = new Color[original.Width * original.Height]; original.GetData<Color>(originalPixelData); Color[] newTextureData = new Color[dataPerPart]; original.GetData<Color>(0, CurrentMap.TileSourceRectangle(mapCell.TileDepths[4]), originalPixelData, 0, originalPixelData.Count()); Texture2D outTexture = new Texture2D(original.GraphicsDevice, partWidth, partheight); } I think the problem is I'm just not understanding the overload of Texture2D.GetData< Part of my concern is creating an array of the whole texture in the first place. Can I target the original texture and create an array of colors for copying based on what I already get from the method TileSourceRecatangle(int)?

  • How to maximize parallel download from S3

    - by StCee
    I got a lot of images to load from Amazon S3 on a single page, and sometimes it takes quite some time to load all the images. I heard that splitting the images to load from different sub-domains would help parallel downloads, however what is the actual implementation on that? While it is easy to split for sub-domains like static,image, etc; Should I make like 10 sub-domains (image1, image2...) to load say 100 images? Or is there some clever ways to do? (By the way I am considering using memcache to cache the S3images; I am not sure if it is possible. I would be grateful for any further comments. Thanks a lot!

  • How can I use my Windows 7 computer to share WiFi connection with PCs that don't have wireless?

    - by Tom Auger
    Long story short: modem and wireless router are downstairs and we're having a LAN party where some visitors don't have wireless. There's no way to run the length of cabling required, so looking for options. My Windows 7 Home Premium PC has a wireless-n connection, and I'd like to see if I can use it as a "hub" or switch of sorts, running an ethernet cable out of the back and into a switch, then splitting off to the other PCs. Is this an option? I know with Internet sharing, you can set up your PC as a wireless access point, but I want to do the opposite.

  • Hardware needed for 2000 users? [closed]

    - by Trcx
    I have school assignment that is fairly well defined, requiring us to come up with a plan for an environment serving dynamic web applications to 2000 users, and should be able to scale up to six thousand. I have done plenty of research as far as load balancing, redundancy, UPSs, etc, but am having a hard time figuring out how much hardware is actually needed in the way of physical servers, ram, processing power, etc. The assignment states that the server will have a lot of dynamic code, email, and a database are required, all utilizing the appropriate microsoft service (MS SQL, Exchange, IIS). I already plan on splitting them out on to separate servers, but can't even fathom the hardware requirements of something that large scale. Could someone with experience weight in on this, or point me two some good articles?

  • In terms of load handling, which is better: one server or two of equivalent power?

    - by seldary
    My goal is to figure out if i'm better off with one strong server, or multiple weaker servers with a load balancer. Does the fact of splitting the load between servers have an effect on the total load my website could take? It's hard to single that out, because there are of course a lot of parameters that affect the results, so some assumptions: Putting failover considerations aside - I know it matters, but for the sake of the question's simplicity, lets assume nothing fails. The servers in the multiple servers option have an accumulated "power" equivalent to the one server option (about the same amount of cores and RAM space). If that is too theoretical, here is a concrete question that could help: Suppose I have several instances of exactly the same server - lets call it S. Suppose that server S can serve a load of up to X calls per time unit. Will two S servers with a load balancer serve 2X calls per time unit? significantly more? significantly less?

  • SQL and IIS HDDs configuration on server

    - by john_1234
    Hi, I've just added a new production server and I was wondering if you guys could help me decide which configuration suits best. Current configuration: 40GB ~ C (System) 250GB ~ D (SQL - MDF & LDF) 250GB ~ F (IIS) 1TB ~ E (storage of users' files) (note: C and D are partitions on the same physical HDD) I've heard splitting LDF/MDF can do magic in terms of performance. Therefore, the core of my question is how would you recommend to do so. For example, putting the MDF with the IIS is an option, yet I'm not so sure about it.

  • Slow queries in Rails- not sure if my indexes are being used.

    - by Max Williams
    I'm doing a quite complicated find with lots of includes, which rails is splitting into a sequence of discrete queries rather than do a single big join. The queries are really slow - my dataset isn't massive, with none of the tables having more than a few thousand records. I have indexed all of the fields which are examined in the queries but i'm worried that the indexes aren't helping for some reason: i installed a plugin called "query_reviewer" which looks at the queries used to build a page, and lists problems with them. This states that indexes AREN'T being used, and it features the results of calling 'explain' on the query, which lists various problems. Here's an example find call: Question.paginate(:all, {:page=>1, :include=>[:answers, :quizzes, :subject, {:taggings=>:tag}, {:gradings=>[:age_group, :difficulty]}], :conditions=>["((questions.subject_id = ?) or (questions.subject_id = ? and tags.name = ?))", "1", 19, "English"], :order=>"subjects.name, (gradings.difficulty_id is null), gradings.age_group_id, gradings.difficulty_id", :per_page=>30}) And here are the generated sql queries: SELECT DISTINCT `questions`.id FROM `questions` LEFT OUTER JOIN `taggings` ON `taggings`.taggable_id = `questions`.id AND `taggings`.taggable_type = 'Question' LEFT OUTER JOIN `tags` ON `tags`.id = `taggings`.tag_id LEFT OUTER JOIN `subjects` ON `subjects`.id = `questions`.subject_id LEFT OUTER JOIN `gradings` ON gradings.question_id = questions.id WHERE (((questions.subject_id = '1') or (questions.subject_id = 19 and tags.name = 'English'))) ORDER BY subjects.name, (gradings.difficulty_id is null), gradings.age_group_id, gradings.difficulty_id LIMIT 0, 30 SELECT `questions`.`id` AS t0_r0 <..etc...> FROM `questions` LEFT OUTER JOIN `answers` ON answers.question_id = questions.id LEFT OUTER JOIN `quiz_questions` ON (`questions`.`id` = `quiz_questions`.`question_id`) LEFT OUTER JOIN `quizzes` ON (`quizzes`.`id` = `quiz_questions`.`quiz_id`) LEFT OUTER JOIN `subjects` ON `subjects`.id = `questions`.subject_id LEFT OUTER JOIN `taggings` ON `taggings`.taggable_id = `questions`.id AND `taggings`.taggable_type = 'Question' LEFT OUTER JOIN `tags` ON `tags`.id = `taggings`.tag_id LEFT OUTER JOIN `gradings` ON gradings.question_id = questions.id LEFT OUTER JOIN `age_groups` ON `age_groups`.id = `gradings`.age_group_id LEFT OUTER JOIN `difficulties` ON `difficulties`.id = `gradings`.difficulty_id WHERE (((questions.subject_id = '1') or (questions.subject_id = 19 and tags.name = 'English'))) AND `questions`.id IN (602, 634, 666, 698, 730, 762, 613, 645, 677, 709, 741, 592, 624, 656, 688, 720, 752, 603, 635, 667, 699, 731, 763, 614, 646, 678, 710, 742, 593, 625) ORDER BY subjects.name, (gradings.difficulty_id is null), gradings.age_group_id, gradings.difficulty_id SELECT count(DISTINCT `questions`.id) AS count_all FROM `questions` LEFT OUTER JOIN `answers` ON answers.question_id = questions.id LEFT OUTER JOIN `quiz_questions` ON (`questions`.`id` = `quiz_questions`.`question_id`) LEFT OUTER JOIN `quizzes` ON (`quizzes`.`id` = `quiz_questions`.`quiz_id`) LEFT OUTER JOIN `subjects` ON `subjects`.id = `questions`.subject_id LEFT OUTER JOIN `taggings` ON `taggings`.taggable_id = `questions`.id AND `taggings`.taggable_type = 'Question' LEFT OUTER JOIN `tags` ON `tags`.id = `taggings`.tag_id LEFT OUTER JOIN `gradings` ON gradings.question_id = questions.id LEFT OUTER JOIN `age_groups` ON `age_groups`.id = `gradings`.age_group_id LEFT OUTER JOIN `difficulties` ON `difficulties`.id = `gradings`.difficulty_id WHERE (((questions.subject_id = '1') or (questions.subject_id = 19 and tags.name = 'English'))) Actually, looking at these all nicely formatted here, there's a crazy amount of joining going on here. This can't be optimal surely. Anyway, it looks like i have two questions. 1) I have an index on each of the ids and foreign key fields referred to here.

  • Using boost locks for RAII access to a semaphore

    - by dan
    Suppose I write a C++ semaphore class with an interface that models the boost Lockable concept (i.e. lock(); unlock(); try_lock(); etc.). Is it safe/recommended to use boost locks for RAII access to such an object? In other words, do boost locks (and/or other related parts of the boost thread library) assume that the Lockable concept will only be modeled by mutex-like objects which are locked and unlocked from the same thread? My guess is that it should be OK to use a semaphore as a model for Lockable. I've browsed through some of the boost source and it "seems" OK. The locks don't appear to store explicit references to this_thread or anything like that. Moreover, the Lockable concept doesn't have any function like whichThreadOwnsMe(). It also looks like I should even be able to pass a boost::unique_lock<MySemaphore> reference to boost::condition_variable_any::wait. However, the documentation is not explicitly clear about the requirements. To illustrate what I mean, consider a bare-bones binary semaphore class along these lines: class MySemaphore{ bool locked; boost::mutex mx; boost::condition_variable cv; public: void lock(){ boost::unique_lock<boost::mutex> lck(mx); while(locked) cv.wait(lck); locked=true; } void unlock(){ { boost::lock_guard<boost::mutex> lck(mx); if(!locked) error(); locked=false; } cv.notify_one(); } // bool try_lock(); void error(); etc. } Now suppose that somewhere, either on an object or globally, I have MySemaphore sem; I want to lock and unlock it using RAII. Also I want to be able to "pass" ownership of the lock from one thread to another. For example, in one thread I execute void doTask() { boost::unique_lock<MySemaphore> lock(sem); doSomeWorkWithSharedObject(); signalToSecondThread(); waitForSignalAck(); lock.release(); } While another thread is executing something like { waitForSignalFromFirstThread(); ackSignal(); boost::unique_lock<MySemaphore>(sem,boost::adopt_lock_t()); doMoreWorkWithSameSharedObject(); } The reason I am doing this is that I don't want anyone else to be able to get the lock on sem in between the time that the first thread executes doSomeWorkWithSharedObject() and the time the second executes doMoreWorkWithSameSharedObject(). Basically, I'm splitting one task into two parts. And the reason I'm splitting the task up is because (1) I want the first part of the task to get started as soon as possible, (2) I want to guarantee that the first part is complete before doTask() returns, and (3) I want the second, more time-consuming part of the task to be completed by another thread, possibly chosen from a pool of slave threads that are waiting around to finish tasks that have been started by master threads. NOTE: I recently posted this same question (sort of) here http://stackoverflow.com/questions/2754884/unlocking-a-mutex-from-a-different-thread-c but I confused mutexes with semaphores, and so the question about using boost locks didn't really get addressed.

  • Regex to leave desired string remaining and others removed

    - by m7d
    In Ruby, what regex will strip out all but a desired string if present in the containing string? I know about /[^abc]/ for characters, but what about strings? Say I have the string "group=4&type_ids[]=2&type_ids[]=7&saved=1" and want to retain the pattern group=\d, if it is present in the string using only a regex? Currently, I am splitting on & and then doing a select with matching condition =~ /group=\d/ on the resulting enumerable collection. It works fine, but I'd like to know the regex to do this more directly.

  • split currency and amount from a string

    - by webber
    I am importing a file which has amount with different currency signs £12.10 $26.13 €12.50 I need to import and convert this into single currency. I am splitting the string as follows $parts = split(' ', preg_replace("/([0-9])/", ' ${1}', $amount, 1)); Couldn't make preg_split work with PREG_SPLIT_DELIM_CAPTURE $parts = preg_split("/\d/", $amount, 2, PREG_SPLIT_DELIM_CAPTURE); I have an array of currency sign to currency code $currencySymbols = array('£'=>'GBP', '$'=>'USD','€'=>'EUR') I need to 1. split the string into currency sign and value - if there is a better way then what i am doing 2. map the currency sign to currency code. Not able to map with $currencySymbols[$parts[0]] Any help will be appreciated. (PHP 5.2.6) using charset=utf-8 Many thanks

  • Entity Framework - Medium Trust

    - by Echilon
    I'm trying to get the entity framework working in medium trust. I've tried splitting the files and using a separate assembly but I seem to have one problem after another. I moved the EDMX to a separate assembly, which causes a single .dll to be outpit to the sites /Bin directory. I'm referencing this as below from web.config. Whenever I try to access one of the entity classes, I get an ArgumentException: 'An item with the same key has already been added.' It's critical this works with medium trust, but I seem to be running out of options. Any advice greatly appreciated.

  • PHP Explode with an Unicode character as separator

    - by Young Roger
    XPDFs pdftotext converts pdf to text and outputs it at command line level. If needed it inserts PageBreaks between the pages as specified in TextOutputDev.cc: eopLen = uMap->mapUnicode(0x0c, eop, sizeof(eop)); This Unicode symbol is encoding independent, -enc ASCII7 wouldn't change it. I'm currently willing to use PHP for converting and splitting the PDF file into several TXT pages for database storage. However, the following function does work, but takes twice as long as a conversion of the whole book in one time. for($i = 1; $i <= $pages[0]; $i++) $page[$i] = shell_exec('/usr/bin/pdftotext sample.pdf -f '.$i.' -l '.$i.' -'); How am I supposed to explode(0x0c, $wholePDF) with an Unicode character as separator? Currently, page[$i] doesn't seem to retrieve those weird Unicode PageBreak characters from the shell_exec(). I tried several headers for encoding (UTF-8 especially) but it didn't work out so far.

  • unwanted quote marks in output from printf

    - by Gary
    I have some address data which has been exported from a database. If the address had multiple lines, the exported data has joined all the lines into one string with the former lines being separated by dollars signs. Here's one of the addresses: INFORMATION DELIVERY DEPT$704 CHERRY ST$ATLANTA, GA 30332-0900 I'm splitting this into an array on the dollar sign and outputting the three array elements into separate tab-separated fields with printf. For some reason, it comes out like this: INFORMATION DELIVERY DEPT 704 CHERRY ST "ATLANTA, GA 30332-0900" I don't want the quotes around that final field. Can anyone explain why this is happening and how to suppress it? This is being done in Windows Vista with gawk3.1.6. Thanks! gary
