  • MySQL enters another value that the one given by PHP

    - by Tristan
    Hello, The big problem : mysql does not stores the information i told him to via PHP Example (this req is an echo just before the query) : INSERT INTO serveur (GSP_nom , IPserv, port, tickrate, membre, nomPays, finContrat, type, jeux, slot, ipClient, email) VALUES ( 'ckras', '88.191.88.57', '37060', '100' , '', 'Allemagne','20110519', '2', '4','99' ,'82.220.201.183','[email protected]'); But on the MySQL i have : 403 ckras 88.191.88.57 32767 100 Allemagne 20110519 1 2010-04-25 00:51:47 2 4 99 82.220.201.183 [email protected] port : 37060 (right value) //// 32767 (MySQL's drug?) Any help would be appreciated, i'm worse than stuck and i'm ** off PS: *There is no trigger on the mysql as far as i know / there is no controll on the port which means that nowhere i modify the "port" value and this script works for 80% of the time ( it seems that as soon as the users enters a port = 30000 it causes that bug), an user first reported to me this error today and the script was running since 3 months* Thanks

  • Flex Custom UIComponents

    - by user164142
    I have created a graph component in AS3 which extends UIComponent. I created an mxml component which is just a Label. The idea is to use the label component to show the values on the graph when you hover over points. I have tried two approaches. Create the Label component using ClassFactory inside the graph so it gets created in the graph component and addChild is called there. The problem is it is always 0 in size. Create in main mxml file and pass in to graph using a setter, the sizing is perfect but the x an y dont relate to my graph :( I suppose its similar to flex and itemrenderers, but in my case i have a graph and another component which can be changed, at the moment it is just a Label. Thanks Neil

  • Can Gitosis enforce correct user name/email?

    - by koumes21
    Gitosis is able to authenticate users based on public/private key pair. It is able to find out which user is currently committing. However, the user name and email is taken from the client's Git configuration ('git config user.name' etc.), which can be set to arbitrary values. Is there any way to associate user names and emails with their public keys and then make Gitosis uses these names and emails as the name and email of the committer? I do not care if I will use Gitosis or WebDAV or some other alternative to share the repository. It just seems to me that none of the available methods supports this enforcement of using some kind of "correct" user name and email. If there exists some alternative, please tell me about it.

  • Hit Testing with CALayer using the alpha properties of the CALayer contents.

    - by Charliehorse
    I'm writing a game for Mac using Cocoa. I'm currently implementing hit testing and have founds that CALayer offers hit testing, but does not seem to implement the alpha properties. As I have at times many CALayers stacked on top of each other, I really need to find a way to determine what the user actually meant to click on. I'm thinking if I could somehow get an array that contains pointers to all of the CALayers that contain the click point, I could filter through them some how. However the only way I've got so far to create the array is: NSMutableArray* anArrayOfLayers = [NSMutableArray array]; for (CALayer* aLayer in mapLayer.sublayers) { if ([aLayer containsPoint:mouseCoord]) [anArrayOfLayers addObject:aLayer]; } Then sort the array by the CALayer's z-values then go through checking if the pixel at location is alpha or not. However, between the sort and the alpha check this seems to be an incredible performance hog. (How would you even check the alpha?) Is there any way to do this?

  • Multi join query returns to many results and improperly matched

    - by Woot4Moo
    I have the following minimal schema in Oracle: http://sqlfiddle.com/#!4/c1ed0/14 The queries I have run yield too many results and this query: select cat.*, status.*, source.* from cats cat, status status, source source Left OUTER JOIN source source2 on source2.sourceid = 1 Right OUTER JOIN status status2 on status2.isStray =0 order by cat.name will yield incorrect results. What I am expecting is a table that looks like the following however I cannot seem to come up with the correct SQL. NAME AGE LENGTH STATUSID CATSOURCE ISSTRAY SOURCEID CATID Adam 1 25 null null null 1 2 Bill 5 1 null null null null null Charles 7 5 null null null null null Steve 12 15 1 1 1 1 1 In plain English what I am looking for is to return all known cats + their associated cat source + their cat status while retaining null values. The only information I will have is the source that I am curious about. I also only want the cats that have a status of either STRAY or UNKNOWN (null)

  • Multivalue Mysql Inserts using HibernateTemplate

    - by Langali
    I am using Spring HibernateTemplate and need to insert hundreds of records into a mysql database every second. Not sure what is the most performant way of doing it, but I am trying to see how the multi value mysql inserts do using hibernate. String query = "insert into user(age, name, birth_date) values(24, 'Joe', '2010-05-19 14:33:14'), (25, 'Joe1', '2010-05-19 14:33:14')" getHibernateTemplate().execute(new HibernateCallback(){ public Object doInHibernate(Session session) throws HibernateException, SQLException { return session.createSQLQuery(query).executeUpdate(); } }); But I get this error: 'could not execute native bulk manipulation query.' Please check your query ..... Any idea of I can use a multi value mysql insert using Hibernate? or is my query incorrect? Any other ways that I can improve the performance? I did try the saveOrUpdateAll() method, and that wasn't good enough!

  • Read random lines from huge CSV file in Python

    - by jbssm
    I have this quite big CSV file (15 Gb) and I need to read about 1 million random lines from it. As far as I can see - and implement - the CSV utility in Python only allows to iterate sequentially in the file. It's very memory consuming to read the all file into memory to use some random choosing and it's very time consuming to go trough all the file and discard some values and choose others, so, is there anyway to choose some random line from the CSV file and read only that line? I tried without success: import csv with open('linear_e_LAN2A_F_0_435keV.csv') as file: reader = csv.reader(file) print reader[someRandomInteger] A sample of the CSV file: 331.093,329.735 251.188,249.994 374.468,373.782 295.643,295.159 83.9058,0 380.709,116.221 352.238,351.891 183.809,182.615 257.277,201.302 61.4598,40.7106

  • newline character on text area

    - by Prady
    I have a custom field called Current_Address__c which is of datatype textarea. I need to populate this field in the format below. ie a newline char after street and another newline after zip. street City state Zip Country The values of city state zip country etc are been taken from contact object. I dont want to use this as a formula field. So i need to populate it in my controller and display it on my VF page. I am trying to add a newline char by using the code below this.customobj.Current_Address__c = currentStreet + '\\n ' + currentCity + ' ' + currentState + ' ' + currentZIP + '\\n ' + currentCountry ; i had also used \n instead of \n. It still show the field in one line instead of 3 lines

  • Better method for flipping multidimensional array?

    - by sudowned
    I've retrieved some data from the database, which is in the following structure: [0] [item_id] = 197 [dice_chat_css] = "foo" [dice_image] = "bar.png" [1] [item_id] = 128 [dice_chat_css] = "foo" [dice_image] = "bar.png" The most convenient and computationally inexpensive way for me to pass this data to the rest of my (PHP) application is with item_id as the index, because it saves having to loop over the array to look up values. If this was a flat array, I could accomplish this trivially with array_flip, but since it isn't, it's my pick of using either the multidimensional array_flip listed in the comments on PHP.net, or roll my own logic: for ($i = 0; $i < sizeOf($r); $i++){ $s[$r[$i]['item_id']]['dice_image'] = $r[$i]['dice_image']; $s[$r[$i]['item_id']]['dice_chat_css'] = $r[$i]['dice_chat_css']; } I know it's simple, but it feels like I'm reinventing the wheel here. Is there an accepted, more optimized method available or am I being weird about this?

  • 128bit hash comparison with SSE

    - by fokenrute
    Hi, In my current project, I have to compare 128bit values (actually md5 hashes) and I thought it would be possible to accelerate the comparison by using SSE instructions. My problem is that I can't manage to find good documentation on SSE instructions; I'm searching for a 128bit integer comparison instruction that let me know if one hash is larger, smaller or equal to another. Does such an instruction exists? PS: The targeted machines are x86_64 servers with SSE2 instructions; I'm also interested in a NEON instruction for the same job.

  • Downloading large files with AFNetworking

    - by goodfella
    I'm trying to implement downloading of a large file and show to user current progress, but block in: -[AFURLConnectionOperation setDownloadProgressBlock:] returns incorrect bytesRead and totalBytesRead values (they are smaller than they should be). For example: If I have a 90MB file and when it downloads completely, latest block invocation in setDownloadProgressBlock: gives me totalBytesRead value about 30MB. On other side, if file is 2MB large, latest block invocation gives correct totalBytesRead 2MB value. AFNetworking is updated to the latest version from github. If AFNetworking can't do it correctly, what solution can I use? Edit: I've determined that even if file is not downloaded completely (and this happens every time with relatively big file) AFNetworking calls success block in: -[AFHTTPRequestOperation setCompletionBlockWithSuccess:failure] I asked a similar question here about this situation, but didn't get any answers. I can check in code downloaded and real file sizes, but AFNetworking has no API for continuation of partial download.

  • rails large amount of data in single insert activerecord gave out

    - by Nik
    So I have I think around 36,000 just to be safe, a number I wouldn't think was too large for a modern sql database like mysql. Each record has just two attributes. So I do: so I collected them into one single insert statement sql = "INSERT INTO tasks (attrib_a, attrib_b) VALUES (c1,d1),(c2,d2),(c3,d3)...(c36000,d36000);" ActiveRecord::Base.connection.execute sql from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/abstract_adapter.rb:219:in `log' from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/mysql_adapter.rb:323:in `execute_without_analyzer from c:/r/projects/vendor/plugins/rails-footnotes/lib/rails-footnotes/notes/queries_note.rb:130:in `execute' from C:/Ruby/lib/ruby/1.8/benchmark.rb:308:in `realtime' from c:/r/projects/vendor/plugins/rails-footnotes/lib/rails-footnotes/notes/queries_note.rb:130:in `execute' from (irb):53 from C:/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/vendor/tzinfo-0.3.12/tzinfo/time_or_datetime.rb:242 I don't know if the above info is enough, please do ask for anything that I didn't provide here. So any idea what this is about? THANK YOU!!!!

  • [Linux] domain socket "sendto" encounter "errno 111, connection refused"

    - by z.cHris
    I am using domain socket to get values from another process, like A to get a value from B, It works well for months. But recently, A is failed during "sendto" message to B with "errno 111, connection refused" occasionally. I checked the B domain socket bind file, it is exists. I also do some tests in another machine, also works well. So, does anyone encounter this problem before? Can anyone have some clues what might be probably wrong in this scenario? Thanks very much.

  • [Ruby] How can I randomly iterate through a large Range?

    - by void
    I would like to randomly iterate through a range. Each value will be visited only once and all values will eventually be visited. For example: (0..9).sort_by{rand}.map{|x| f(x)} where f(x) is some function that operates on each value. A Fisher-Yates shuffle could be used to increase efficiency, but this code is sufficient for many purposes. My problem is that sort_by will transform the range into an array, which is not cool because I am working with astronomically large numbers. Ruby will quickly consume a large amount of RAM trying to create a monstrous array. This is also why the following code will not work: tried = {} # store previous attempts bigint = 99**99 bigint.times { x = rand(bigint) redo if tried[x] tried[x] = true f(x) # some function } This code is very naive and quickly runs out of memory as tried obtains more entries. What sort of algorithm can accomplish what I am trying to do?

  • mysql conditional query - complicated!

    - by emre
    i want to get distinct values for a field, let say: field1... ok this needs a query like: "select distint(field1) from table" however for some records, field1 is empty and there is another column that is an alternative to field1, which is field2. now; for the records where field1 is empty i need to use the value of field2. i think i need sort of a conditional select statement with if control something like: "select distinct( (if(field1!='') field1 else field2) ) from table" but i have no idea on how to write it. any help is appricated...

  • What's your favorite implementation of producing the fibonacci sequence?

    - by Terry Donaghe
    Best, most creative, most clever, fastest, smallest, written in weirdest language, etc etc. For those not familiar with this staple of programming exam question / interview question, check this out: Fibonacci Sequence at Wikipedia The question would be, write a simple program which will spit out the first n digits of the Fibonacci sequence. So, if n == 12, we produce: 0 1 1 2 3 5 8 13 21 34 55 89 144 Your implementation becomes more interesting when you set n to larger values. How long does it take your implementation to return a 25 digit sequence? How about 100?

  • Stagger increments in C# NumericUpDown control

    - by mihe
    Hi cloud of wisdom :-) I am facing some trouble trying to configure a particular configuration for a NumericUpDown control in c#. Basically, I have seen that I can set the Increment interval, but I would like to manage the Increment interval depending on which arrow is clicked (up or down). I have checked the events of the control, but I do not find an event for each arrow. Basically, I want to achieve a control where, at different values, the increment is different. from 0.00 to 5.00 increments of 0.01, from 5.00 to 20.00 increments of 0.04, and so on Is this possible ? Note: It would be useful also an historic value in the control for the last value when the valuechanged event is trigger. Does this exist? Thanks in advance for any comment or suggestion!!!

  • Count down timer

    - by Ohmnastrum
    I have a timer set up and it gets called when ever the player is in their turn phase. I also have a multiplier that decrements slowly while the player is committing actions. for some odd reason my mult variable is returning garbage values I initialized it to 1 in the onLoad statement but it still seems to have trouble. -(void) Timerbar:(NSTimer *)barTimer { if(!waitForPlayer) { [barTimer invalidate]; } if(mult > 0.0) { mult -= 0.01; if(mult < 0) { mult = 0; } } power = (mult * 10) / pwrBarMaxWidth; pwrBarWidth = (int)power % limit; NSLog(@"%d", mult); } Do I have a syntax error somewhere?

  • Circular dock/menu in css or jquery

    - by sasidhar
    Is it possible to have a circular menu or dock using css or jquery.? I have a set of images as the dock items that need to be displayed as a circular dock... however the number of items in the dock are not constant and may vary.... so i cannot tend to use constant values for positioning each item in a pre-defined manner. Ajax loads some images into this particular div and i need to use css or jquery to style this so that they get displayed as circular dock items. Any idea on how this can be implemented..? I would like a browser in-specific implementation, but i also welcome if some one has some solutions specific to few browsers... UPDATE I don't think i exactly want a pie menu... it easily gets messed up as the number of dock items increase. I am looking for a spiral dock. and by spiral i mean that the menu items must be in the following alignment..

  • casting BSTR as char* in a dll; different results depnding on VB/C# caller.

    - by Toby Wilson
    I have a dll function that takes BSTR parameters. These are casted as char* before being used for other things. When the dll is called from VB code this works fine. However, when it is called from C# code, only the first character is pointed to. Both of these are excel addIns for Pre-2007 and 2007+ versions of Office, which call into a faster C++ AddIn. They actually call it directly, not through Excel. The VB function declaration looks like this: Private Declare Function Test Lib "ExcelAddIn.xll" (ByVal param As String) As String The C# function declaration looks like this: [DllImport("ExcelAddIn.xll", CharSet=CharSet.Ansi)] [return:MarshalAs(UnmanagedType.BStr)] private static extern string Test([MarshalAs(UnmanagedType.BStr)] string param); When debugging the dll and watching the input BSTR values, they appear to be correct from both; just the C# one only casts the first character. Charset=CharSet.Unicode makes no difference. Any ideas anyone?

  • Error handling and polymorphism

    - by Neeraj
    I have an application with some bunch of code like this: errCode = callMainSystem(); switch (errCode){ case FailErr: error("Err corresponding to val1\n"); case IgnoreErr: error("Err corresponding to val2\n"); ... ... default: error("Unknown error\n"); } The values are enum constants. Will it make some sense to have something like: // Error* callMainSystem() ... Some code return FaileErr(); // or some other error // handling code Error* err = callMainSystem(); err->toString(); The Error class may be made singleton as it only has to print error messages. What are the pros and cons of above methods,size is an important criteria as the application needs to be supported on embedded devices as well. P.S: I don't want to use exception handling because of portability issues and associated overheads.

  • ASP.NET calendar drawing control

    - by BCS
    I want to make a simple ASP.NET page that draws a months from a calendar and highlights given dates. (I'm not looking for a date picker.) What I have is a list of DateTime values and I need to display them a a nice way. Given that I'm a total beginner with ASP, simpler really is better. (I'd rather not, I'm willing to hack together something with StringBuilder and <table> if it's easier). p.s. I have no budget, so non-free controls will only be of use to other readers.

  • Read multiple strings from a file C++

    - by user69514
    Hi I need to read different values stored in a file one by one. So I was thinking I can use ifstream to open the file, but since the file is set up in such a way that a line might contain three numbers, and the other line one number or two numbers I'm not sure how to read each number one by one. I was thinking of using stringstream but I'm not sure if that would work. The file is a format like this. 52500.00 64029.50 56000.00 65500.00 53780.00 77300.00 44000.50 80100.20 90000.00 41000.00 60500.50 72000.00 I need to read each number and store it in a vector. What is the best way to accomplish this? Reading one number at a time even though each line contains a different amount of numbers?

  • Mercurial: How to ignore changes to a tracked file

    - by Svish
    I have a file with database settings in my project which I have set to some defaults. The file is tracked by mercurial and checked in. Since this file will be edited with different values various developer machines, is there a way I can tell Mercurial to ignore new changes to this file? I tried adding the file to the .hgignore file, but since the file is tracked it isn't ignored. This is alright and good in other situations, but I am wondering if there is something I can do here.
