  • I can't seem to figure out type variables mixed with classes.

    - by onmach
    I pretty much understand 3/4 the rest of the language, but every time I dip my feet into using classes in a meaningful way in my code I get permantently entrenched. Why doesn't this extremely simple code work? data Room n = Room n n deriving Show class HasArea a where width :: (Num n) => a -> n instance (Num n) => HasArea (Room n) where width (Room w h) = w So, room width is denoted by ints or maybe floats, I don't want to restrict it at this point. Both the class and the instance restrict the n type to Nums, but it still doesn't like it and I get this error: Couldn't match expected type `n1' against inferred type `n' `n1' is a rigid type variable bound by the type signature for `width' at Dungeon.hs:11:16 `n' is a rigid type variable bound by the instance declaration at Dungeon.hs:13:14 In the expression: w In the definition of `width': width (Room w h) = w In the instance declaration for `HasArea (Room n)' So it tells me the types doesn't match, but it doesn't tell me what types it thinks they are, which would be really helpful. As a side note, is there any easy way to debug an error like this? The only way I know to do it is to randomly change stuff until it works.

  • Get node parent of defined type using xpath

    - by IordanTanev
    Hi, i will give an example of the problem i have. My XML is like this <roor> <child Name = "child1"> <node> <element1>Value1</element1> <element2>Value2</element2> </node> </child> <child Name = "child2"> <element1>Value1</element1> <element2>Value2</element2> <element3>Value3</element3> </child> </root> I have xpath expression that returns all "element2" nodes. Then i want to for every node of type "element2" to find the node of type "child" that contains it. The problem is that between these two nodes there can be from 1 to n different nodes so i can't just use "..". Is there something like "//" that will look up instead of down Best Regards, Iordan

  • JAVA : How to get the positions of all matches in a String?

    - by user692704
    I have a text document and a query (the query could be more than one word). I want to find the position of all occurrences of the query in the document. I thought of the documentText.indexOf(query) and using regular expression but I could not make it work. I end up with the following method: First, I have create a dataType called QueryOccurrence public class QueryOccurrence implements Serializable{ public QueryOccurrence(){} private int start; private int end; public QueryOccurrence(int nameStart,int nameEnd,String nameText){ start=nameStart; end=nameEnd; } public int getStart(){ return start; } public int getEnd(){ return end; } public void SetStart(int i){ start=i; } public void SetEnd(int i){ end=i; } } Then, I have used this datatype in the following method: public static List<QueryOccurrence>FindQueryPositions(String documentText, String query){ // Normalize do the following: lower case, trim, and remove punctuation String normalizedQuery = Normalize.Normalize(query); String normalizedDocument = Normalize.Normalize(documentText); String[] documentWords = normalizedDocument.split(" ");; String[] queryArray = normalizedQuery.split(" "); List<QueryOccurrence> foundQueries = new ArrayList(); QueryOccurrence foundQuery = new QueryOccurrence(); int index = 0; for (String word : documentWords) { if (word.equals(queryArray[0])){ foundQuery.SetStart(index); } if (word.equals(queryArray[queryArray.length-1])){ foundQuery.SetEnd(index); if((foundQuery.End()-foundQuery.Start())+1==queryArray.length){ //add the found query to the list foundQueries.add(foundQuery); //flush the foundQuery variable to use it again foundQuery= new QueryOccurrence(); } } index++; } return foundQueries; } This method return a list of all occurrence of the query in the document each one with its position. Could you suggest any easer and faster way to accomplish this task. Thanks

  • '<=' operator is not working in sql server 2000

    - by Lalit
    Hello, Scenario is, database is in the maintenance phase. this database is not developed by ours developer. it is an existing database developed by the 'xyz' company in sql server 2000. This is real time database, where i am working now. I wanted to write the stored procedure which will retrieve me the records From date1 to date 2.so query is : Select * from MyTableName Where colDate>= '3-May-2010' and colDate<= '5-Oct-2010' and colName='xyzName' whereas my understanding I must get data including upper bound date as well as lower bound date. but somehow I am getting records from '3-May-2010' (which is fine but) to '10-Oct-2010' As i observe in table design , for ColDate, developer had used 'varchar' to store the date. i know this is wrong remedy by them. so in my stored procedure I have also used varchar parameters as @FromDate1 and @ToDate to get inputs for SP. this is giving me result which i have explained. i tried to take the parameter type as 'Datetime' but it is showing error while saving/altering the stored procedure that "@FromDate1 has invalid datatype", same for "@ToDate". situation is that, I can not change the table design at all. what i have to do here ? i know we can use user defined table in sql server 2008 , but there is version sql server 2000. which does not support the same. Please guide me for this scenario. **Edited** I am trying to write like this SP: CREATE PROCEDURE USP_Data (@Location varchar(100), @FromDate DATETIME, @ToDate DATETIME) AS SELECT * FROM dbo.TableName Where CAST(Dt AS DATETIME) >=@fromDate and CAST(Dt AS DATETIME)<=@ToDate and Location=@Location GO but getting Error: Arithmetic overflow error converting expression to data type datetime. in sql server 2000 What should be that ? is i am wrong some where ? also (202 row(s) affected) is changes every time in circular manner means first time sayin (122 row(s) affected) run again saying (80 row(s) affected) if again (202 row(s) affected) if again (122 row(s) affected) I can not understand what is going on ?

  • Editing XML file content with Python.

    - by Hooloovoo
    Hi, I am trying to use Python to read in an XML file containing some parameter names and values, e.g. ... <parameter name='par1'> <value>24</value> </parameter> <parameter name='par2'> <value>Blue/Red/Green</value> </parameter> ... and then pass it a dictionary with the parameter names {'par1':'53','par2':'Yellow/Pink/Black',...} and corresponding new values to replace the old ones in the XML file. The output should then overwrite the original XML file. At the moment I am converting the XML to a python dictionary and after some element comparison and regular expression handling, writing the output again in XML format. I am not too happy with this and was wondering whether anyone can recommend a more efficient way of doing it? Thanks.

  • Is there any alternative way of writing this switch statement(C#3.0)

    - by Newbie
    Can it be done in a better way public static EnumFactorType GetFactorEnum(string str) { Standardization e = new Standardization(); switch (str.ToLower()) { case "beta": e.FactorType = EnumFactorType.BETA; break; case "bkp": e.FactorType = EnumFactorType.BOOK_TO_PRICE; break; case "yld": e.FactorType = EnumFactorType.DIVIDEND_YIELD; break; case "growth": e.FactorType = EnumFactorType.GROWTH; break; case "mean": e.FactorType = EnumFactorType.MARKET_CAP; break; case "momentum": e.FactorType = EnumFactorType.MOMENTUM; break; case "size": e.FactorType = EnumFactorType.SIZE; break; case "stat_fact1": e.FactorType = EnumFactorType.STAT_FACT_1; break; case "stat_fact2": e.FactorType = EnumFactorType.STAT_FACT_2; break; case "value": e.FactorType = EnumFactorType.VALUE; break; } return e.FactorType; } If I create a Static class(say Constatant) and declare variable like public static string BETA= "beta"; and then if I try to put that in the Case expression like Case Constants.BETA : e.FactorType = EnumFactorType.BETA; break; then the compiler will report error.(quite expected) So is there any other way?(I canot change the switch statement) Using C#3.0 Thanks

  • Taking item from string array that *might* be there

    - by AndyC
    Hi all, I have a string array, and it may contain an element with the text "mytext" within the string. eg: mystringarray { [0] => "hello world"; [1] => "some of mytext"; } I also have an array that doesn't have the mytext text in it. mystringarray { [0] => "hello world"; [1] => "some of notmy"; } My problem is when I use: string mytextdata = mystringarray.Single<string>(t => t.Contains("mytext")).ToString(); I get an exception for the second array as it can't find an element that matches the expression. Is there a quick way I can edit this one line to not throw an exception if it finds nothing, and instead just ignore? I have a lot of these lines and I don't want to have to wrap each in an if statement. Apologies if question isn't clear.

  • What does the $1$2$4 mean in this preg_replace?

    - by Taylor
    Got this function for ammending the query string and was wondering what the replacement part of the pre_replace meant (ie- $1$2$4). function add_querystring_var($url, $key, $value) { $url = preg_replace('/(.*)(\?|&)' . $key . '=[^&]+?(&)(.*)/i', '$1$2$4', $url . '&'); $url = substr($url, 0, -1); if (strpos($url, '?') === false) { return ($url . '?' . $key . '=' . $value); } else { return ($url . '&' . $key . '=' . $value); } } Not too familiar with regular expression stuff. I get the various parts to preg_replace but not 100% about the use of '$1$2$4' in the replacement part.

  • C# return and display syntax issue

    - by thatdude
    I am having trouble passing the return value from TheMethod() to Main and displaying the word if the if statement is passed as true. I have thought of two ways of doing this, neither has worked but I think I am missing synatx. Using a return ?; non void method and then displaying the returned value. Using a void method and actually writing out(example below) So yes I am new at this, however I have made so many iterations everything is blending together and I have forgot what I have tried. Any help on the syntax be great for either of these ways. Basically I need it to iterate numbers 1,2,3,4 and depending on if the current iteration matches an expression in the if statements it will display a word. Example: if (3 = i) { Console.WriteLine("Word"); } Code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Proj5 { class Program { int i = 0; static void Main(int i) { for (i = 0; i < 101; i++) { Console.WriteLine("test"); } } string TheMethod(int i) { string f = "Word1"; string b = "Word2"; if (i == 3) { return f; } if (i == 5) { return b; } if (0 == (i % 3)) { return f; } if (0 == i % 5) { return b; } else { return b; } } } }

  • Credit card validation with regexp using test()

    - by Matt
    I'm trying to complete some homework and it appears the book might have gotten it wrong. I have a simple html page that allows user to pick a credit card in our case american express. The user then enters a number and evalutes that number based on a regular expression. My question ends up being when test() evaluates the number it returns a boolean or a string? I should then compare that string or boolean? True == true should fire off the code in a nested if statement. Heres what the book gives me as valid code: if(document.forms[0].cardName.value == "American Express") { var cardProtocol = new RegExp("^3[47][0-9]{13}$"); //REGEX ENTRY HERE if(cardProtocol.test(document.forms[0].cardNumber.value)) document.forms[0].ccResult.value = "Valid credit card number"; } The above code doesn't work in firefox. I've tried modifying it with 2 alerts to make sure the number is good and the boolean is good...and still no luck: if(document.forms[0].cardName.value == "American Express") { var cardProtocol = new RegExp("^3[47][0-9]{13}$"); //REGEX ENTRY HERE <------ alert(document.forms[0].cardNumber.value) alert(cardProtocol.test(document.forms[0].cardNumber.value)) if((cardProtocol.test(document.forms[0].cardNumber.value)) == true ) // <--Problem { document.forms[0].ccResult.value = "Valid credit card number"; } else { document.forms[0].ccResult.value = "Invalid credit card number"; } } Any ideas? the if loop is the culprit but I'm not figuring out why it is not working. Please throw up the code for the if loop! Thanks for the help!

  • C++11 decltype requires instantiated object

    - by snipes83
    I was experimenting a little with the C++11 standard and came up with this problem: In C++11 you can use auto and decltype to automatically get return type for a function as, for example the begin() and end() functions below: #include <vector> template <typename T> class Container { private: std::vector<T> v; public: auto begin() -> decltype(v.begin()) { return v.begin(); }; auto end() -> decltype(v.end()) { return v.end(); }; }; My problem here is that I have to declare the private vector<T> v before the public declarations which is against my coding style. I would like to declare all my private members after my public members. You have to declare the vector before the function declaration because the expression in decltype is a call to vector member function begin() and requires an instance of the object. Is there a way around this?

  • Helicon ISAPI Rewrite Proxy 500 Internal Server Error

    - by Rob Stevenson-Leggett
    Hi, I have a website running at www.domain.com. The client now wants the website to appear to be running under www.otherdomain.com/whatson/brand/ Since the website is umbraco it won't run under a subfolder. I wanted to use ISAPI rewrite to proxy requests to www.domain.com using the following rule in a .htaccess at www.otherdomain.com/whatson/brand/ RewriteRule ^(.*)$ http://www.domain.com/$1 [P,L] However, when I apply this I get an ugly 500 Internal Server Error. There's nothing in the event log. So I turned on ISAPI logging and can see the following 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) init rewrite engine with requested uri /whatson/brand/home.aspx Then it testing all the other rewrite rules on the server. Then this 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (1) Htaccess process request w:\websites\otherdomain.com\docs2\whatson\brand\.htaccess 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (3) applying pattern '^(.*)$' to uri 'home.aspx' 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) forcing proxy-throughput with http://www.domain.com/home.aspx 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (1) go-ahead with proxy request http://www.domain.com/home.aspx [OK] 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) rewrite 'home.aspx' -> '/whatson/brand/home.aspxx.rwhlp?p=0' 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) internal redirect with /whatson/brand/home.aspxx.rwhlp?p=0 [INTERNAL REDIRECT] So it appears to work according to the logs, but I'm not seeing the page come through.. It's worth noting that www.domain.com and www.otherdomain.com are on the same box. LogLevel is 3 and RewriteLogLevel is 3 (I've tried with 9 and debug but there is too much traffic going through the other sites on the box) Any ideas?

  • Could not continue scan with NOLOCK due to data movement during installation

    - by dbdev1
    I am running Windows Server 2008 Standard Edition R2 x64 and I installed SQL Server 2008 Developer Edition. All of the preliminary checks run fine (Apart from a warning about Windows Firewall and opening ports which is unrelated to this and shouldn't be an issue - I can open those ports). Half way through the actual installation, I get a popup with this error: Could not continue scan with NOLOCK due to data movement. The installation still runs to completion when I press ok. However, at the end, it states that the following services "failed": database engine services sql server replication full-text search reporting services How do I know if this actually means that anything from my installation (which is on a clean Windows Server setup - nothing else on there, no previous SQL Servers, no upgrades, etc) is missing? I know from my programming experience that locks are for concurrency control and the Microsoft help on this issue points to changing my query's lock/transactions in a certain way to fix the issue. But I am not touching any queries? Also, now that I have installed the app, when I login, I keep getting this message: TITLE: Connect to Server ------------------------------ Cannot connect to MSSQLSERVER. ------------------------------ ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

I have disabled Windows Firewall temporarily. I have checked the instance name against the error logs. Please advise on both of these errors. I think these two errors are related. Thanks

  • Appcrash and possible malware

  • vhost.conf file in PLESK not working as intended

    - by Saif Bechan
    I have configured a vhost file for my domain but it does not seem to work. These are the steps I took, please correct me if I am wrong. First I made a file called vhost.conf in: /var/www/vhosts/*domain*/conf/vhost.conf The content of the vhost file looks like this: <Directory /var/www/vhosts/*domain*/httpdocs> php_admin_flag engine on php_admin_flag display_errors on </Directory> Now in my /etc/php.ini i set display_errors=Off After everything i rebuild with: /usr/local/psa/admin/sbin/websrvmng -a But I don't see the any errors in my page. When i turn on the display_errors in /etc/php.ini only then can I see the errors. I know for a fact that the vhost file is read, because when i type nonsense values i get an error when restarting apache saying there are errors in the vhost file. Anyone know what the problem can be. Should there be special settings in either the php.ini file or the httpd.conf file. The httpd.conf i edit is in /etc/httpd/conf/httpd.conf. Is this the file that PLESK uses or is there another, because the values i see there do not really reflect the http folders of my domain. The httpd file looks like this now. # The document root DocumentRoot "/var/www/html" # i guess this is the base directory <Directory /> Order Deny,Allow Deny from all Options None AllowOverride None </Directory> # And i guess here are all my domains located, but there aren't any here <Directory "/var/www/html"> Options None AllowOverride None Order allow,deny Allow from all </Directory> Only this directory /var/www/html is not used by me, I use the directory /var/www/vhosts. The only folder found in /var/www/html is a folder called awstats. Does plesk use other files, and where are they located. I hope this all makes sense to anyone, and i hope i can find a solution

  • Could not continue scan with NOLOCK due to data movement during installation

    - by dbdev1
    Hi, I am running Windows Server 2008 Standard Edition R2 x64 and I installed SQL Server 2008 Developer Edition. All of the preliminary checks run fine (Apart from a warning about Windows Firewall and opening ports which is unrelated to this and shouldn't be an issue - I can open those ports). Half way through the actual installation, I get a popup with this error: Could not continue scan with NOLOCK due to data movement. The installation still runs to completion when I press ok. However, at the end, it states that the following services "failed": database engine services sql server replication full-text search reporting services How do I know if this actually means that anything from my installation (which is on a clean Windows Server setup - nothing else on there, no previous SQL Servers, no upgrades, etc) is missing? I know from my programming experience that locks are for concurrency control and the Microsoft help on this issue points to changing my query's lock/transactions in a certain way to fix the issue. But I am not touching any queries? Also, now that I have installed the app, when I login, I keep getting this message: TITLE: Connect to Server Cannot connect to MSSQLSERVER. ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 67) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=67&LinkId=20476 BUTTONS: OK I went into the Configuration Manager and enabled named pipes and restarted the service (this is something I have done before as this message is common and not serious). I have disabled Windows Firewall temporarily. I have checked the instance name against the error logs. Please advise on both of these errors. I think these two errors are related. Thanks

  • Outgrew MongoDB … now what?

    - by samsmith
    We dump debug and transaction logs into mongodb. We really like mongodb because: Blazing insert perf document oriented Ability to let the engine drop inserts when needed for performance But there is this big problem with mongodb: The index must fit in physical RAM. In practice, this limits us to 80-150gb of raw data (we currently run on a system with 16gb RAM). Sooooo, for us to have 500gb or a tb of data, we would need 50gb or 80gb of RAM. Yes, I know this is possible. We can add servers and use mongo sharding. We can buy a special server box that can take 100 or 200 gb of RAM, but this is the tail wagging the dog! We could spend boucoup $$$ on hardware to run FOSS, when SQL Server Express can handle WAY more data on WAY less hardware than Mongo (SQL Server does not meet our architectural desires, or we would use it!) We are not going to spend huge $ on hardware here, because it is necessary only because of the Mongo architecture, not because of the inherent processing/storage needs. (And sharding? Please! Cost aside, who needs the ongoing complexity of three, five, or more servers to manage a relatively small load?) Bottom line: MongoDB is FOSS, but we gotta spend $$$$$$$ on hardware to run it? We sould rather buy commercial SW! I am sure we are not the first to hit this issue, so we ask the community: Where do we go next? (We already run Mongo v2) Thanks!!

    I've installed ffmpeg successfully using the ffmpeginstaller 3 series (http://www.ffmpeginstaller.com/download). ffmpeg is working fine without any known issues with bash.

I've tried to install ffmpeg-php manually but I receive the following error checking for ffmpeg headers... configure: error: ffmpeg headers not found. Make sure you've built ffmpeg as shared libs using the --enable-shared option Should I install ffmpeg with series 4 or 5 of ffmpeginstaller or does someone know how to fix this issue?

  • Tomcat 7 on Ubuntu 12.04 startup issues

    - by Nico Huysamen
    I am having trouble getting tomcat 7 to start up on my new VPS. I am really scratching my head since I have done this often. So I'm thinking it might be the VPS. I just got a new VPS from CINFU. After a clean install of Ubuntu 12.04 32bit, I install openjdk-6-jdk, update JAVA_HOME to point to: /usr/lib/jvm/java-1.6.0-openjdk-i386 and JRE_HOME to: /usr/lib/jvm/java-1.6.0-openjdk-i386/jre But when I try to run: ./catalina.sh run it simply outputs: Using CATALINA_BASE: /opt/tomcat/apache-tomcat-7.0.29 Using CATALINA_HOME: /opt/tomcat/apache-tomcat-7.0.29 Using CATALINA_TMPDIR: /opt/tomcat/apache-tomcat-7.0.29/temp Using JRE_HOME: /usr/lib/jvm/java-1.6.0-openjdk-i386 Using CLASSPATH: /opt/tomcat/apache-tomcat-7.0.29/bin/bootstrap.jar:/opt/tomcat/apache-tomcat-7.0.29/bin/tomcat-juli.jar and stops. It just hangs there doing nothing. If I run ./startup.sh && tail -f ../logs/catalina.out it gets to: Aug 24, 2012 8:38:36 PM org.apache.coyote.AbstractProtocol init INFO: Initializing ProtocolHandler ["http-bio-8080"] Aug 24, 2012 8:38:36 PM org.apache.coyote.AbstractProtocol init INFO: Initializing ProtocolHandler ["ajp-bio-8009"] Aug 24, 2012 8:38:36 PM org.apache.catalina.startup.Catalina load INFO: Initialization processed in 495 ms Aug 24, 2012 8:38:36 PM org.apache.catalina.core.StandardService startInternal INFO: Starting service Catalina Aug 24, 2012 8:38:36 PM org.apache.catalina.core.StandardEngine startInternal INFO: Starting Servlet Engine: Apache Tomcat/7.0.29 but I am unable to access anything. The request just hangs. I have also tried a few other things like explicitly exporting the paths etc in catalina.sh, and running ./startup.sh rather than catalina.sh, but the furthest I have gotten is that it finishes deploying all the WARs (the default ones that comes with tomcat like the host-manager etc), but then it hangs: Aug 24, 2012 8:47:30 PM org.apache.coyote.AbstractProtocol init INFO: Initializing ProtocolHandler ["http-bio-8080"] and does nothing. Anyone have any pointers that might help? As I said, I must really be missing something stupid since this has worked on all other VPSs that we have. UPDATE I figured out that the problem is actually the fact that they use OpnVZ virtualization and that there are known compatibility problems with Java.

  • what can be causes of http server crash?

    - by mithunmo
    Hello , I am using WAMP server on Windows XP. Apache 2.2.11 MySQL 5.1.36 (INNODB engine) PHP 5.3.0 I observe that my WAMP server crashes in the following scenarios IF I use a Low end PC ( low processor speed and low RAM) After making some changes to httpd.conf file .For eg changing the Allow from IP address . But here it crashes only once and then it starts to work fine. Random crashes CRASH LOG szAppName : httpd.exe szAppVer : 2.2.11.0 szModName : php5ts.dll szModVer : 5.3.0.0 offset : 0000c309 C:\DOCUME~1\blrcom\LOCALS~1\Temp\WERc677.dir00\httpd.exe.mdmp C:\DOCUME~1\blrcom\LOCALS~1\Temp\WERc677.dir00\appcompat.txt My questions Does high CPU utilization/LOW RAM can also cause the HTTP server to crash ? excessive file reading as in every 10 seconds ? unlimited script execution time . I have set the maximum execution time in php script to 0 as my script has to execute for sometimes 2-3 days. Is there any way to avoid this ? Access to Database ? Should we use lock before reading and writing Can these be the reasons for random wamp server crashes ? OR is is some other programming error ? Please guide me . Regards, Mithun
