  • makefile pattern rules: single wildcard, multiple instances in prerequisite

    - by johndashen
    Hi all, hopefully this is a basic question about make pattern rules: I want to use a wildcard more than once in a prerequisite for a rule, i.e. in my Makefile I have data/%P1.m: $(PROJHOME)/data/%/ISCAN/%P1.RAW @echo " Writing temporary matlab file for $*" # do something data/%P2.m: $(PROJHOME)/data/%/ISCAN/AGP2.RAW @echo " Writing temporary matlab file for $*" # do something In this example, I try to invoke make when the wildcard % is AG. Both files $(PROJHOME)/data/AG/ISCAN/AGP1.RAW and $(PROJHOME)/data/AG/ISCAN/AGP2.RAW exist. I attempt the following make commands and get this output: [jshen@iLab10 gender-diffs]$ make data/AGP1.m make: *** No rule to make target `data/AGP1.m'. Stop. [jshen@iLab10 gender-diffs]$ make data/AGP2.m Writing temporary matlab file for AG, part 2... [jshen@iLab10 gender-diffs]$ ls data/AG/ISCAN/AG* data/AG/ISCAN/AGP1.RAW data/AG/ISCAN/AGP2.RAW How can I implement multiple instances of the same wildcard in the first make rule?

  • How to join mysql tables

    - by Ivan
    I've an old table like this: user> id | name | address | comments And now I've to create an "alias" table to allow some users to have an alias name for some reasons. I've created a new table 'user_alias' like this: user_alias> name | user But now I have a problem due my poor SQL level... How to join both tables to generate something like this: 1 | my_name | my_address | my_comments 1 | my_alias | my_address | my_comments 2 | other_name | other_address | other_comments I mean, I want to make a "SELECT..." query that returns in the same format as the "user" table ALL users and ALL alias.. Something like this: SELECT user.* FROM user LEFT JOIN user_alias ON `user`=`id` but it doesn't work for me..

These activex control from big and trusted company, other developers work with them.

  • Parsing Indentation-based syntaxes in Haskell's Parsec

    - by pavpanchekha
    I'm trying to parse an indentation-based language (think Python, Haskell itself, Boo, YAML) in Haskell using Parsec. I've seen the IndentParser library, and it looks like it's the perfect match, but what I can't figure out is how to make my TokenParser into an indentation parser. Here's the code I have so far: import qualified Text.ParserCombinators.Parsec.Token as T import qualified Text.ParserCombinators.Parsec.IndentParser.Token as IT lexer = T.makeTokenParser mylangDef ident = IT.identifier lexer This throws the error: parser2.hs:29:28: Couldn't match expected type `IT.TokenParser st' against inferred type `T.GenTokenParser s u m' In the first argument of `IT.identifier', namely `lexer' In the expression: IT.identifier lexer In the definition of `ident': ident = IT.identifier lexer What am I doing wrong? How should I create an IT.TokenParser? Or is IndentParser broken and to be avoided?

  • Deploying a Rails App to Multiple Servers using Capistrano - Best Practices

    - by Louise
    I have a rails application that I need to deploy to 3 servers - machine1.com, machine2.com and machine3.com. I want to be able to deploy it to all machines at once and each machine individually. Can someone help me out with a skeleton Capistrano config file / recipe? Should it all be in deploy.rb or should I break it out in machine1.rb, etc? I thought I was on the right track getting Capistrano to take in command line arguments, but it choked when I tried set the roles within the namespaces. I'd pass in 'hosts=1,2,3' as an argument and set the role:app/web/db to "machine#{host}.com" after splitting on the command and going into an each do |host| {}... Anyway, other than creating 4 different deploy.rb files and renaming it before running cap:deploy each time, I'm stumped. I'd like to be able to do the following: cap deploy:machine1:latest_version_from_svn cap deploy:all_machines:latest:version_from_svn Just don't know if it should all be in deploy.rb split up with namespaces or if it should be broken into multiple deploy*.rb files.

  • WPF Binding Collection To ComboBox and Selecting an item

    - by Adam Driscoll
    I've been knocking my head against this for some time now. I'm not really sure why it isn't working. I'm still pretty new to this whole WPF business. Here's my XAML for the combobox <ComboBox Width="200" SelectedValuePath="Type.FullName" SelectedItem="{Binding Path=Type}" Name="cmoBox" > </ComboBox> Here's what populates the ComboBox (myAssembly is a class I created with a list of possible types) cmoBox.ItemsSource = myAssembly.PossibleTypes; I set the DataContext in a parent element of the ComboBox in the code behind like this: groupBox.DataContext = listBox.SelectedItem; I want the binding to select the correct "possible type" from the combo box. It doesn't select anything. I have tried SelectedValue and SelectedItem. When I changed the DisplayMemberPath of the ComboBox to a different property it changed what was displayed so I know it's not completely broken. Any ideas???

  • best way to statistically detect anomalies in data

    - by reinier
    Hi, our webapp collects huge amount of data about user actions, network business, database load, etc etc etc All data is stored in warehouses and we have quite a lot of interesting views on this data. if something odd happens chances are, it shows up somewhere in the data. However, to manually detect if something out of the ordinary is going on, one has to continually look through this data, and look for oddities. My question: what is the best way to detect changes in dynamic data which can be seen as 'out of the ordinary'. Are bayesan filters (I've seen these mentioned when reading about spam detection) the way to go? Any pointers would be great! EDIT: To clarify the data for example shows a daily curve of database load. This curve typically looks similar to the curve from yesterday In time this curve might change slowly. It would be nice that if the curve from day to day changes say within some perimeters, a warning could go off. R

  • Javascript Getting a string into kb format

    - by Teske
    I am new to javascript and I just wanted to convert a string into a format that a person like me can read. Here is an example of what I am trying to do... string2size(string){ //some awesome coding I have no clue how to make return awesomeAnswer } now the return should give me something like 56 bytes or 12kb or 1mb depending how much the string is. so if the string is... string = "there was an old woman who lived in a shoe"; then string2size(string) should return something like 3kb. Now I know there has been a utf8 talk and I wouldn't object to and addition of that to the function. I have tried google and Yahoo searches but they talk of using php but I really need it for javascript. I do thank anyone for their time. -Teske

  • How to remotely control a Windows Service with ServiceController?

    - by Amokrane
    Hi, I'm trying to control Windows Services that are installed in a remote computer. I'm using the ServiceController class. I have this: ServiceController svc = new ServiceController("MyWindowsService", "COMPUTER_NAME"); With this, I can get the status of the Windows Service like this: string status = svc.Status.ToString(); But I can't control the Windows Service (by doing svc.Start(); or svc.Stop();). I get the following exception: Cannot open Servicexxx service on computer 'COMPUTER_NAME' That's normal, I suppose there is something to do with access permissions. But how? I've looked into Google but didn't find what I was looking for. However I often read something related to impersonation, but I don't know what that means. NB: The local and remote computers are both running Win XP Pro. Thanks.

  • Use API or SQL to detect new Support Tickets?

    - by David Powers
    I currently work for a company that uses Kayako for their support system. They sell an extra program called Insta Alert that plays a sound when a new ticket is submitted. I use WHMCS for my own company, and would like to develop something to work with it that does the same thing. Here is the WHMCS API... http://wiki.whmcs.com/API:Functions I am wondering if it would make more sense from a remote C++ application to use the API or just check the MySQL database for new tickets? This is not really something im overly familiar with (I usually make mods) but it doesn't seem overly difficult. I just want some assistance in choosing the best approach.

  • what is the right way to exit Windoes Service OnStart if configuration is wrong and nothing to do in

    - by matti
    Is something like this ok? protected override void OnStart(string[] args) { if (SomeApp.Initialize()) { SomeApp.StartMonitorAndWork(); base.OnStart(args); } } protected override void OnStop() { SomeApp.TearDown(); base.OnStop(); } Here Initialize reads a config file and if it's wrong there's nothing to do so service should STOP! If config is ok StartMonitorAndWork starts: Timer(new TimerCallback(DoWork), null, startTime, loopTime); and DoWork polls database periodically. The question is: "Is exiting OnStart without doing nothing enough if Initialize returns false? OR should there be something like this: private void ExitService() { this.OnStop(); System.Environment.Exit(1); } protected override void OnStart(string[] args) { if (ObjectFolderApp.Initialize()) { SomeApp.StartMonitorAndWork(); base.OnStart(args); } else { ExitService(); } } Thanks & BR - Matti

  • Push notifications work for Ad Hoc, but not when downloaded from the Apple store.

    - by MikeQ
    My app just got approved for the apple store. I downloaded it an installed it on my iPhone - but it looks like push notifications are broken! I was successfully testing push notifications in production using an adHoc provisioning profile. I had no problems. The only thing I did differently when I submitted to apple was using an app store distribution profile. The application never asks me (or anyone else who has downloaded it) if I want to receive push notifications. Consequently, the phone never talks to my server to send the push token (because application:didRegisterForRemoteNotificationsWithDeviceToken: is presumably never called). Also the application does not appear in the settings app under the notification settings. What could I be doing wrong??

  • Code working in jsFiddle but not in browser...

    - by Jascination
    I'm trying to run the following code, written on my local machine: http://www.jsfiddle.net/WShdx/3/ Functionality-wise (ignore the broken images in the previous and next buttons, and the wrongly-sized main images) the click/hover function is working properly in jsfiddle. However, on my local machine it's not working at all. For all intents and purposes the code is identical, except the local copy has this head section to load in the javascript/css files that are contained within the jsfiddle page: <head> <title>Jquery Wizard</title> <link href="style.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script> <script src="wizard.js" type="text/javascript" ></script> </head> Is there some wonderful function of jsFiddle that is making my code magically work, or am I missing something here?

  • Using ManagementObject to retrieve a single WMI property

    - by Jesse
    This probably isn't the best way, but I am currently retrieving the amount of RAM on a machine using: manageObjSearch.Query = new ObjectQuery("SELECT TotalVisibleMemorySize FROM Win32_OperatingSystem"); manageObjCol = manageObjSearch.Get(); foreach (ManagementObject mo in manageObjCol) sizeInKilobytes = Convert.ToInt64(mo["TotalVisibleMemorySize"]); It works well and good, but I feel I could be doing this more directly and without a foreach over a single element, but I can't figure out how to index a ManagementObjectCollection I want to do something like this: ManagementObject mo = new ManagementObject("Win32_OperatingSystem.TotalVisibleMemorySize") mo.Get(); Console.WriteLine(mo["TotalVisibleMemorySize"].ToString()) or maybe even something like ManagementClass mc = new ManagementClass("Win32_OperatingSystem"); Console.WriteLine(mc.GetPropertyValue("TotalVisibleMemorySize").ToString()); I just can't seem to figure it out. Any ideas?

  • Objective PHP and key value coding

    - by Lukasz
    Hi Guys. In some part of my code I need something like this: $product_type = $product->type; $price_field = 'field_'.$product_type.'_price'; $price = $product->$$price_field; In other words I need kind of KVC - means get object field by field name produced at the runtime. I simply need to extend some existing system and keep field naming convention so do not advice me to change field names instead. I know something like this works for arrays, when you could easily do that by: $price = $product[$price_field_key]. So I can produce key for array dynamically. But how to do that for objects? Please help me as google gives me river of results for arrays, etc... Thank you

  • How do I take advantage of Android's "Clear Cache" button

    - by Jay Askren
    In Android's settings, in the "Manage Applications" activity when clicking on an app, the data is broken down into Application, Data, and cache. There is also a button to clear the cache. My app caches audio files and I would like the user to be able to clear the cache using this button. How do I store them so they get lumped in with the cache and the user can clear them? I've tried storing files using both of the following techniques: newFile = File.createTempFile("mcb", ".mp3", context.getCacheDir()); newFile = new File(context.getCacheDir(), "mcb.mp3"); newFile.createNewFile(); In both cases, these files are listed as Data and not Cache.

  • Should I obscure primary key values?

    - by Scott
    I'm building a web application where the front end is a highly-specialized search engine. Searching is handled at the main URL, and the user is passed off to a sub-directory when they click on a search result for a more detailed display. This hand-off is being done as a GET request with the primary key being passed in the query string. I seem to recall reading somewhere that exposing primary keys to the user was not a good idea, so I decided to implement reversible encryption. I'm starting to wonder if I'm just being paranoid. The reversible encryption (base64) is probably easily broken by anybody who cares to try, makes the URLs very ugly, and also longer than they otherwise would be. Should I just drop the encryption and send my primary keys in the clear?

  • Select from multiple tables, remove duplicates

    - by staze
    I have two tables in a SQLite DB, and both have the following fields: idnumber, firstname, middlename, lastname, email, login One table has all of these populated, the other doesn't have the idnumber, or middle name populated. I'd LIKE to be able to do something like: select idnumber, firstname, middlename, lastname, email, login from users1,users2 group by login; But I get an "ambiguous" error. Doing something like: select idnumber, firstname, middlename, lastname, email, login from users1 union select idnumber, firstname, middlename, lastname, email, login from users2; LOOKS like it works, but I see duplicates. my understanding is that union shouldn't allow duplicates, but maybe they're not real duplicates since the second user table doesn't have all the fields populated (e.g. "20, bob, alan, smith, [email protected], bob" is not the same as "NULL, bob, NULL, smith, [email protected], bob"). Any ideas? What am I missing? All I want to do is dedupe based on "login". Thanks!

  • Parse http GET and POST parameters from BaseHTTPHandler?

    - by ataylor
    BaseHTTPHandler from the BaseHTTPServer module doesn't seem to provide any convenient way to access http request parameters. What is the best way to parse the GET parameters from the path, and the POST parameters from the request body? Right now, I'm using this for GET: def do_GET(self): parsed_path = urlparse.urlparse(self.path) try: params = dict([p.split('=') for p in parsed_path[4].split('&')]) except: params = {} This works for most cases, but I'd like something more robust that handles encodings and cases like empty parameters properly. Ideally, I'd like something small and standalone, rather than a full web framework.

But I can't able to get it right. Any idea?

  • NSOutlineView with Drag and Drop

    - by bob
    I read the other post here on Outlineviews and DND, but I can't get my program to work. At the bottom of this post is a link to a zip of my project. Its very basic with only an outlineview and button. I want it to receive text files being dropped on it, but something is wrong with my code or connections. I tried following Apple's example code of their NSOutline Drag and Drop, but I'm missing something. 1 difference is my program is a document based program and their example isn't. I set the File's Owner to receive delegate actions, since that's where my code to handle drag and drop is, as well as a button action. Its probably a simple mistake, so could someone please look at it and tell me what I'm doing wrong? Here is a link to the file: http://www.4shared.com/file/or1A7aHk/OutlineDragDrop.html
