  • Get the last day of the last month in csh?

    - by ANE
    How do you get the last day of the last month in csh? Here is the code so far. The cal command below works if you execute it from the (FreeBSD sh) command line, but I'm having trouble escaping it properly to run within a script. #!/bin/csh set lastdayoflastmonth=`cal `date '+%m'` `date '+%Y'` | grep . | fmt -1 | tail -1` echo $lastdayoflastmonth

  • tfidf, am I understanding it right?

    - by alskndalsnd
    Hey everyone, I am interested in doing some document clustering, and right now I am considering using TF-IDF for this. If I am not wrong, TFIDF is particularly used for evaluating the relevance of a document given a query. If I do not have a particular query, how can I apply tfidf to clustering?

  • Parameterized include in Classic ASP with VBScript

    - by Thom Smith
    I want to write a function that will include an external file, much like Server.Execute, but will pass along parameters. I'm aware that Server.Execute will pass along query parameters, but I'd like to pass data more generally. For instance: ' main.asp MyInclude("external.inc", Array("mykey", "myval")) ' external.inc Response.Write mykey I doubt I can get quite that far without reading the external fine, twiddling it, and executing, but I'd like to get as close as reasonably possible. Also, if possible, I'd prefer avoiding using the query passing option for security reasons.

  • SharePoint LDAP filtering of People Picker users

    - by 78lro
    Hi On my WSS server I have run the following stsadm command to filter the people picker results: stsadm.exe -o setproperty -url http://myserver -pn "peoplepicker-searchadcu stomfilter" -pv "(memberOf=CN=SharePoint,OU=AccessGroups,DC=contosio,DC=local)" My WSS sites are all used by different groups of users. Whenever I create a new site collection in WSS I want to ensure that I can filter the people picker to only show he relevant users for that group - can I automate this or would I have to manually do something like the above stsadm command? All the best

  • untar filename.tr.gz to directory "filename"

    - by Jorre
    I would like to untar an archive e.g. "tar123.tar.gz" to directory /myunzip/tar123/" using a shell command. tar -xf tar123.tar.gz will decompress the files but in the same directory as where I'm working in. If the filename would be "tar233.tar.gz" I want it to be decompressed to /myunzip/tar233.tar.gz" so destination directory would be based on the filename. Does anyone know if the tar command can do this?

  • Spring validation errors not displayed

    - by Art Vandelay
    I have the following situation. I have a validator to validate my command object and set the errors on a Errors object to be displayed in my form. The validator is invoked as expected and works okay, but the errors i set on the Errors objects are not displayed, when i am sent back to my form because of the validation errors. Validator: public void validate(Object obj, Errors err) { MyCommand myCommand = (MyCommand) obj; int index = 0; for (Field field : myCommand.getFields()) { if (field.isChecked()) { if ((field.getValue() == null) || (field.getValue().equals(""))) { err.rejectValue("fields[" + index + "].value", "errors.missing"); } } index++; } if (myCommand.getLimit() < 0) { err.rejectValue("limit", "errors.invalid"); } } Command: public class MyCommand { private List<Field> fields; private int limit; //getters and setters } public class Field { private boolean checked; private String name; private String value; //getters and setters } Form: <form:form id="myForm" method="POST" action="${url}" commandName="myCommand"> <c:forEach items="${myCommand.fields}" var="field" varStatus="status"> <form:checkbox path="fields[${status.index}].checked" value="${field.checked}" /> <c:out value="${field.name}" /> <form:input path="fields[${status.index}].value" /> <form:errors path="fields[${status.index}].value" cssClass="error" /></td> <form:hidden path="fields[${status.index}].name" /> </c:forEach> <fmt:message key="label.limit" /> <form:input path="limit" /> <form:errors path="limit" cssClass="error" /> </form:form> Controller: @RequestMapping(value = REQ_MAPPING, method = RequestMethod.POST) public String onSubmit(Model model, MyCommand myCommand, BindingResult result) { // validate myCommandValidator.validate(myCommand, result); if (result.hasErrors()) { model.addAttribute("myCommand", myCommand); return VIEW; } // form is okay, do stuff and redirect } Could it be that the paths i give in the validator and tag are not correct? The validator validates a command object containing a list of objects, so that's why i give a index on the list in the command object when registering an error message (for example: "fields["+index+"]".value). Or is it that the Errors object containing the errors is not available to my view? Any help is welcome and appreciated, it might give me a hint or point me in right direction.

  • redirect prints to log file

    - by lakshmipathi
    Okay. I have completed my first python program.It has around 1000 lines of code. During development I placed plenty of print stmt before running a command using os.system() say something like, print "running command",cmd os.system(cmd) Now I have completed the program.I thought about commenting them but redirecting all these unnecessary print (i can't remove all print stmt- since some provide useful info for user) into a log file will be more useful? Any tricks or tips.

  • XML Return from an Oracle Stored Procedure

    - by Tequila Jinx
    Unfortunately most of my DB experience has been with MSSQL which tends to hold your hand a lot more than Oracle. What I'm trying to do is fairly trivial in tSQL, however, pl/sql is giving me a headache. I have the following procedure: CREATE OR REPLACE PROCEDURE USPX_GetUserbyID (USERID USERS.USERID%TYPE, USERRECORD OUT XMLTYPE) AS BEGIN SELECT XMLELEMENT("user" , XMLATTRIBUTES(u.USERID AS "userid", u.companyid as "companyid", u.usertype as "usertype", u.status as "status", u.personid as "personid") , XMLFOREST( p.FIRSTNAME AS "firstname" , p.LASTNAME AS "lastname" , p.EMAIL AS "email" , p.PHONE AS "phone" , p.PHONEEXTENSION AS "extension") , XMLELEMENT("roles", (SELECT XMLAGG(XMLELEMENT("role", r.ROLETYPE)) FROM USER_ROLES r WHERE r.USERID = USERID AND r.ISACTIVE = 1 ) ) , XMLELEMENT("watches", (SELECT XMLAGG( XMLELEMENT("watch", XMLATTRIBUTES(w.WATCHID AS "id", w.TICKETID AS "ticket") ) ) FROM USER_WATCHES w WHERE w.USERID = USERID AND w.ISACTIVE = 1 ) ) ) AS "RESULT" INTO USERRECORD FROM USERS u LEFT JOIN PEOPLE p ON p.PERSONID = u.PERSONID WHERE u.USERID = USERID; END USPX_GetUserbyID; When executed, it should return an XML document with the following structure: <user userid="" companyid="" usertype="" status="" personid=""> <firstname /> <lastname /> <email /> <phone /> <extension /> <roles> <role /> </roles> <watches> <watch id="" ticket="" /> </watches> </user> When I execute the query itself, replacing the USERID parameter with a string and removing the "into" clause, the query runs fine and returns the expected structure. However, when the procedure attempts to execute the query, passing the results of the XMLELEMENT function into the USERRECORD output parameter, I get the following exception: Error report: ORA-01422: exact fetch returns more than requested number of rows ORA-06512: at "USPX_GETUSERBYID", line 4 ORA-06512: at line 3 01422. 00000 - "exact fetch returns more than requested number of rows" *Cause: The number specified in exact fetch is less than the rows returned. *Action: Rewrite the query or change number of rows requested I'm baffled trying to nail this down, and unfortunately my google-fu hasn't helped. I've found plenty of Oracle SQL|XML examples, but none that deal with XML returns from a procedure. Note: I know that an alternate method of retrieving XML using DBMS methods exists, however, it's my understanding that that functionality is deprecated in favor of SQL|XML.

  • How do I change bash history completion to complete what's already on the line?

    - by blokkie
    I found a command a couple of months ago that made my bash history auto-complete on what's already on the line when pressing the up arrow: $ vim fi Press ? $ vim file.py I'd like to set this up on my new computer, because it saves a lot of time when keeping a big history. The problem is that I can't for the life of me remember where it was mentioned and reading through endless bash references and tutorials unfortunately didn't help either. Does anybody know the command?

  • How to design this ?

    - by Akku
    how can i make this entire process as 1 single event??? http://code.google.com/apis/visualization/documentation/dev/dsl_get_started.html and draw the chart on single click? I am new to servlets please guide me When a user clicks the "go " button with some input. The data goes to the servlet say "Test3". The servlet processes the data by the user and generates/feeds the data table dynamically Then I call the html page to draw the chart as shown in the tutorial link above. The problem is when I call the servlet it gives me a long json string in the browser as given in the tutorials "google.visualization.Query.setResponse({version:'0.6',status:'ok',sig:'1333639331',table:{cols:[{............................" Then when i manually call the html page to draw the chart i am see the chart. But when I call html page directly using the request dispatcher via the servlet I dont get the result. This is my code and o/p...... I need sugession as to how should be my approach to call the chart public class Test3 extends HttpServlet implements DataTableGenerator { protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { DataSourceHelper.executeDataSourceServletFlow(request, response, this , isRestrictedAccessMode() ); RequestDispatcher rd; rd = request.getRequestDispatcher("new.html");// it call's the html page which draws the chart as per the data added by the servlet..... rd.include(request, response);//forward(request, response); @Override public Capabilities getCapabilities() { return Capabilities.NONE; } protected boolean isRestrictedAccessMode() { return false; } @Override public DataTable generateDataTable(Query query, HttpServletRequest request) { // Create a data table. DataTable data = new DataTable(); ArrayList<ColumnDescription> cd = new ArrayList<ColumnDescription>(); cd.add(new ColumnDescription("name", ValueType.TEXT, "Animal name")); cd.add......... I get the following result along with unprocessed html page google.visualization.Query.setResponse({version:'0.6',statu..... <html> <head> <title>Getting Started Example</title> .... Entire html page as it is on the Browser. What I need is when a user clicks the go button the servlet should process the data and call the html page to draw the chart....Without the json string appearing on the browser.(all in one user click) What should be my approach or how should i design this.... there are no error in the code. since when i run the servlet i get the json string on the browser and then when i run the html page manually i get the chart drawn. So how can I do (servlet processing + html page drawing chart as final result) at one go without the long json string appearing on the browser. There is no problem with the html code....

  • How does MySQL's ORDER BY RAND() work?

    - by Eugene
    Hi, I've been doing some research and testing on how to do fast random selection in MySQL. In the process I've faced some unexpected results and now I am not fully sure I know how ORDER BY RAND() really works. I always thought that when you do ORDER BY RAND() on the table, MySQL adds a new column to the table which is filled with random values, then it sorts data by that column and then e.g. you take the above value which got there randomly. I've done lots of googling and testing and finally found that the query Jay offers in his blog is indeed the fastest solution: SELECT * FROM Table T JOIN (SELECT CEIL(MAX(ID)*RAND()) AS ID FROM Table) AS x ON T.ID >= x.ID LIMIT 1; While common ORDER BY RAND() takes 30-40 seconds on my test table, his query does the work in 0.1 seconds. He explains how this functions in the blog so I'll just skip this and finally move to the odd thing. My table is a common table with a PRIMARY KEY id and other non-indexed stuff like username, age, etc. Here's the thing I am struggling to explain SELECT * FROM table ORDER BY RAND() LIMIT 1; /*30-40 seconds*/ SELECT id FROM table ORDER BY RAND() LIMIT 1; /*0.25 seconds*/ SELECT id, username FROM table ORDER BY RAND() LIMIT 1; /*90 seconds*/ I was sort of expecting to see approximately the same time for all three queries since I am always sorting on a single column. But for some reason this didn't happen. Please let me know if you any ideas about this. I have a project where I need to do fast ORDER BY RAND() and personally I would prefer to use SELECT id FROM table ORDER BY RAND() LIMIT 1; SELECT * FROM table WHERE id=ID_FROM_PREVIOUS_QUERY LIMIT 1; which, yes, is slower than Jay's method, however it is smaller and easier to understand. My queries are rather big ones with several JOINs and with WHERE clause and while Jay's method still works, the query grows really big and complex because I need to use all the JOINs and WHERE in the JOINed (called x in his query) sub request. Thanks for your time!

  • PDO fails to prepare a statement with over 13 placeholders
