  • How to delete a file that contains a backslash in the name under Windows 7?

    - by espinchi
    I want to delete a file named workspaces\google-gson-1.7.1-release.zip Yep, it contains a backslash in the name. Here it is: G:\>dir Z_DRIVE Volume in drive G is samsung Volume Serial Number is 48B9-7E1D Directory of G:\Z_DRIVE 04/06/2012 08:09 PM <DIR> . 04/06/2012 08:09 PM <DIR> .. 05/01/2011 02:21 PM 528,016 workspaces\google-gson-1.7.1-release.zip 1 File(s) 528,016 bytes 2 Dir(s) 88,400,478,208 bytes free The first attempt is to just delete it from the Windows Explorer, but it says it can't find the file. Then, I tried from the command line: G:\>del Z_DRIVE\workspaces\google-gson-1.7.1-release.zip The system cannot find the file specified. And, after researching a bit in the internets, I also tried the following, with no luck: G:\>del \\?\G:\Z_DRIVE\workspaces\google-gson-1.7.1-release.zip The system cannot find the file specified. Other than booting from some Linux CD, is there a way to get rid of this file? Update: also tried the following combinations, but the error is the same: G:\>del "\\?\G:\Z_DRIVE\workspaces\google-gson-1.7.1-release.zip" G:\Z_DRIVE>del workspaces\google-gson-1.7.1-release.zip G:\Z_DRIVE>del "workspaces\google-gson-1.7.1-release.zip" G:\Z_DRIVE>del workspaces*google-gson-1.7.1-release.zip

  • How do I make a symlink to every directory in the current directory that has the same name but has u

    - by Jason Baker
    For instance, I suppose I have a directory that contains the following folders foo_bar baz What I would like to have is a bash command that will make a symlink foo-bar to foo_bar so it would look like this: foo-bar foo_bar baz I'm pretty sure I can write a Python script to do this, but I'm curious if there's a way to do this with bash. Here's where I'm stuck: ls -1 | grep _ | xargs -I {} ln -s {} `{} | sed 's/_/-/'` What I'm trying to do is run the command ln -s with the first argument being the directory name and the second argument being that name passed through sed s/_/-/. Is there another way to do this?

  • Is it possible to map static IP to computer name instead of MAC address?

    - by xenon
    I have a number of computers with different hostnames connected to the network. They currently hold a static IP address based on their MAC address. In other words, the static IP address is mapped to their MAC address. This gives rise to a problem and that's when we swap the harddrive from one computer to another, the MAC address becomes different and the application we are running on the harddrive has problem getting the right static IP for it to work. We can't configure the IP address in the application all the time. And changing the static IP addresses to re-map to the computer's new MAC address can be quite a pain. Since all the computers have a unique computer name as their hostname, is it possible to configure such that when these computers grab IP addresses from the DHCP server, DHCP will learn about their hostname and assign the correct IP address? This is to say, the static IP is mapped to the computers' hostname instead of their MAC address. All the computers are running on Windows 7. Would this be possible? If so how should I go about do this?

  • Fix Fatal Error Condition showing system path

    - by JMC
    I've noticed there are a large number of servers running Magento Commerce that will return a fatal error showing the system path: Fatal error: Uncaught exception 'Exception' with message 'File '/usr/local/www/magento/data1702/media/css' does not exists.' in /usr/local/www/magento/data1702/lib/Varien/File/Transfer/Adapter/Http.php:96 Stack trace: #0 /usr/local/www/magento/data1702/get.php(205): Varien_File_Transfer_Adapter_Http->send('/usr/local/www/...') #1 /usr/local/www/magento/data1702/get.php(165): sendFile('/usr/local/www/...') #2 {main} thrown in /usr/local/www/magento/data1702/lib/Varien/File/Transfer/Adapter/Http.php on line 96 Magento as an application is generally good about supressing error messages. How can a linux server running apache be configured to avoid returning this error message since the app has problems suppressing it.

  • How do we name test methods where we are checking for more than one condition?

    - by Sandbox
    I follow the technique specified in Roy Osherove's The Art Of Unit Testing book while naming test methods - MethodName_Scenario_Expectation. It suits perfectly well for my 'unit' tests. But,for tests that I write in 'controller' or 'coordinator' class, there isn't necessarily a method which I want to test. For these tests, I generate multiple conditions which make up one scenario and then I verify the expectation. For example, I may set some properties on different instances, generate an event and then verify that my expectation from controller/coordinator is being met. Now, my controller handles events using a private event handler. Here my scenario is that, I set some properties, say 3 condition1,condition2 and condition3 Also, my scenario includes an event is raised I don't have a method name as my event handler is private. How do I name such a test method?

  • Partial Function Application

    - by AngelEyes
    This is long overdo... Just a short and simple example of Partial Function Application.   For some good explanations, which also include the difference between Currying and Partial Function Application, check out: http://msmvps.com/blogs/jon_skeet/archive/2012/01/30/currying-vs-partial-function-application.aspx and also this answer on stackoverflow: http://stackoverflow.com/a/8826698/532517   And here is the example, taken from real code:           internal void Addfile(string parentDirName, string fileName, long size)         {             AddElement(parentDirName, fileName, (name, parent) => new File(name, size, parent));         }           public void AddDir(string parentDirName, string dirName)         {             AddElement(parentDirName, dirName, (name, parent) => new Directory(dirName, parent));         }           private void AddElement(string parentDirName, string name,                                 Func<string, FileSystemElement, FileSystemElement> elementCreator)         {             ValidateFileNames(parentDirName, name);             var parent = (Directory)_index[parentDirName];             FileSystemElement element = elementCreator(name, parent);             parent._elements.Add(element);             _index.Add(name, element);         }

  • How to change the app name in OSX menubar in a pure-Python application bundle?

    - by gyim
    I am trying to create a pure-Python application bundle for a wxPython app. I created the .app directory with the files described in Apple docs, with an Info.plist file etc. The only difference between a "normal" app and this bundle is that the entry point (CFBundleExecutable) is a script which starts with the following line: #!/usr/bin/env python2.5 Everything works fine except that the application name in the OSX menubar is still "Python" although I have set the CFBundleName in Info.plist (I copied the result of py2app, actually). The full Info.plist can be viewed here: http://tinyurl.com/32qgpjt How can I change this? I have read everywhere that the menubar name is only determined by CFBundleName. How is it possible that the Python interpreter can change this in runtime? Note: I was using py2app before, but the result was too large (50 MB instead of the current 100KB) and it was not even portable between Leopard and Snow Leopard... so it seems to be much easier to create a pure-Python app bundle "by hand" than transforming the output of py2app.

  • Git is not using the first editor in my $PATH

    - by GuillaumeA
    I am using OS X 10.8, and I used brew to install a more recent version of emacs than the one shipped with OS X. The newer emacs binary is installed in /usr/local/bin (24.2.1), and the old "shipped-with-osx" one in /usr/bin (22.1.1). I updated my $PATH env variable by prepending /usr/local/bin to it. It works fine in my shell (ie. typing emacs runs the 24.2.1 version), but when git opens the editor, the emacs version is 22.1.1. Isn't git supposed to use $PATH to find the editor I want to use ? Additional informations: $ type -a emacs emacs is /usr/local/bin/emacs emacs is /usr/bin/emacs emacs is /usr/local/bin/emacs $ env PATH=/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin SHELL=/bin/zsh PAGER=most EDITOR=emacs -nw _=/usr/bin/env Please note that I'd prefer not to set the absolute path of my editor directly in my git conf, as I use this conf across multiple systems. EDIT: Here's an bit of my .zshrc: # Mac OS X if [ `uname` = "Darwin" ]; then # Brew binaries PATH="/usr/local/bin":"/usr/local/sbin":$PATH else # Everyone else (Linux) # snip fi So, yes, I could add a line export EDITOR='/usr/local/bin emacs -nw' in the first if, but I'd like to understand why git is not using my PATH variable :)

  • How can I get Text property to initialize to the objects name at design time?

    - by cyclotis04
    When you add a label to the form from the toolbox, its text defaults to the item's name (label1, label2, etc). How can I make this happen with a custom control? So far, I have the following, which allows me to change the text through the property window: private string _text; [BrowsableAttribute(true)] public override string Text { get { return _text; } set { _text = value; lblID.Text = _text; } } Apparently the above code works as is, but I'm not sure why. Does Text default to the object's name automatically? The question still stands for other properties which don't override Text.

  • Is domain-transfer inherently safe for downtime when the name servers remain the same?

    - by jlmt
    I've been reading around this topic towards understanding whether there's some or no chance of downtime during an upcoming domain transfer for 15 live and very critical domains. In our case there are three companies involved: CompanyA is the original registrar and DNS host, CompanyB is the new DNS host, and CompanyC is the new registrar. I've already changed the nameservers for all domains to those of CompanyB. We suffered some downtime because CompanyA deleted their hosted DNS for our domains directly after the change, but the changes propagated and we're now able to configure our DNS with CompanyB. From what I understand (please correct where wrong!): There exists an SOA record that points oneofourdomains.com to ns.companyb.com. That record is maintained and authoritatively hosted by the ccTLD registry for the domain (eg. Verisign for .com). CompanyA currently has the ability to change the SOA record because they're the registrar. There exist NS records for oneofourdomains.com, which are also related to the link from domain name to nameserver, are similarly hosted by the ccTLD, and which CompanyA are also able to change while acting as registrar. Neither CompanyB nor CompanyC currently have any control over the SOA or NS records. CompanyA are unable to cause us (DNS) problems during the transfer by dropping service early, because they are not the authoritative source for the SOA and NS records. When we transfer the domains, it's administrative control of the SOA and NS records that will be transferred to CompanyC. As long as we advise CompanyC that the SOA and NS records must not change (as regards pointing to CompanyB's nameservers), there's no need for any kind of DNS change, and therefore no possibility of downtime. Is my understanding of this correct? My fear is that CompanyA will somehow cut us off again, and their support dept hasn't given me much confidence in their understanding of the topic.

  • Grails: Duplicates & unique constraint validation

    - by rukoche
    OK here is stripped down version of what I have in my app Artist domain: class Artist { String name Date lastMined def artistService static transients = ['artistService'] static hasMany = [events: Event] static constraints = { name(unique: true) lastMined(nullable: true) } def mine() { artistService.mine(this) } } Event domain: class Event { String name String details String country String town String place String url String date static belongsTo = [Artist] static hasMany = [artists: Artist] static constraints = { name(unique: true) url(unique: true) } } ArtistService: class ArtistService { def results = [ [ name:"name", details:"details", country:"country", town:"town", place:"place", url:"url", date:"date" ] ] def mine(Artist artist) { results << results[0] // now we have a duplicate results.each { def event = new Event(it) if (event.validate()) { if (artist.events.find{ it.name == event.name }) { log.info "grrr! valid duplicate name: ${event.name}" } artist.addToEvents(event) } } artist.lastMined = new Date() if (artist.events) { artist.save(flush: true) } } } In theory event.validate() should return false and event will not be added to artist, but it doesn't.. which results in DB exception on artist.save() Although I noticed that if duplicate event is persisted first everything works as intended. Is it bug or feature? :P

  • how to emulate thread local storage at user space in C++ ?

    - by vprajan
    I am working on a mobile platform over Nucleus RTOS. It uses Nucleus Threading system but it doesn't have support for explicit thread local storage i.e, TlsAlloc, TlsSetValue, TlsGetValue, TlsFree APIs. The platform doesn't have user space pthreads as well. I found that __thread storage modifier is present in most of the C++ compilers. But i don't know how to make it work for my kind of usage. How does __thread keyword can be mapped with explicit thread local storage? I read many articles but nothing is so clear for giving me the following basic information will __thread variable different for each thread ? How to write to that and read from it ? does each thread has exactly one copy of the variable ? following is the pthread based implementation: pthread_key_t m_key; struct Data : Noncopyable { Data(T* value, void* owner) : value(value), owner(owner) {} int* value; }; inline ThreadSpecific() { int error = pthread_key_create(&m_key, destroy); if (error) CRASH(); } inline ~ThreadSpecific() { pthread_key_delete(m_key); // Does not invoke destructor functions. } inline T* get() { Data* data = static_cast<Data*>(pthread_getspecific(m_key)); return data ? data->value : 0; } inline void set(T* ptr) { ASSERT(!get()); pthread_setspecific(m_key, new Data(ptr, this)); } How to make the above code use __thread way to set & get specific value ? where/when does the create & delete happen? If this is not possible, how to write custom pthread_setspecific, pthread_getspecific kind of APIs. I tried using a C++ global map and index it uniquely for each thread and retrieved data from it. But it didn't work well.

  • count(*) vs count(row-name) - which is more correct?

    - by bread
    Does it make a difference if you do count(*) vs count(row-name) as in these two examples? I have a tendency to always write count(*) because it seems to fit better in my mind with the notion of it being an aggregate function, if that makes sense. But I'm not sure if it's technically best as I tend to see example code written without the * more often than not. count(*): select customerid, count(*), sum(price) from items_ordered group by customerid having count(*) > 1; vs. count(row-name): SELECT customerid, count(customerid), sum(price) FROM items_ordered GROUP BY customerid HAVING count(customerid) > 1;

  • Extending jQuery Form Validation Script for new form fields

    - by user982124
    I have a simple HTML form that originally was a series of Questions (A1 to A5 and B1 to B3) with yes/no radio buttons like this: <tr> <td width="88%" valign="top" class="field_name_left">A1</td> <td width="12%" valign="top" class="field_data"> <input type="radio" name="CriteriaA1" value="Yes">Yes<input type="radio" name="CriteriaA1" value="No">No</td> </tr> The user could only answer either the A series of questions OR either the B series of questions, but not both. Also they must complete all questions in either the A or B series. I now have an additional series of questions - C1 to C6 - and need to extend my validation scripts to ensure the user enters either A, B or C and answers all questions within each series. My original script for just the A and B looks like this: $(function() { $("#editRecord").submit(function(){ // is anything checked? if(!checkEmpty()){ $("#error").html("Please check something before submitting"); //alert("nothing Checked"); return false; } // Only A _OR_ B if(isAorB()){ $("#error").html("Please complete A or B, not both"); //alert("please complete A or B, not both"); return false; }; // all A's or all B's if(allAorBChecked()){ $("#error").html("It appears you have not completed all questions"); //alert("missing data"); return false; }; if(haveNo()){ // we're going on, but sending "type = C" } //alert("all OK"); return true; }); }); function checkEmpty(){ var OK = false; $(":radio").each(function(){ if (this.checked){ OK = true; } }); return OK; } function isAorB(){ var OK = false; var Achecked = false; var Bchecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); // if we have an A checked remember it if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } if(Achecked && theChar == "B" && !Bchecked){ if(this.checked){ Bchecked = true; } } if (Achecked && Bchecked){ OK = true; } }); return OK; } function allAorBChecked(){ var notOK = false; var Achecked = false; $(":radio").each(function(){ // skip through to see if we're doing A's or B's var theChar=this.name.charAt(8); // check the A's if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } }); if(Achecked){ // set the input to A $("#type").val("A"); // check _all_ a's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "A"){ if (this.name == thisName && !thisChecked){ // Yes wasn't checked - is No? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); }else{ // set the input to B $("#type").val("B"); // check _all_ b's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "B"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } function haveNo(){ var thisName; var notOK = false; $(":radio").each(function(){ var checked = this.checked; if (this.name == thisName){ //Is this checked if(checked){ notOK = true; $("#type").val("C"); } } thisName = this.name; }); return notOK; } This worked well but I'm completely stuck at extending it to include the C series. I now have to check that the user hasn't answered any A and B, A and C and B and C questions. Everything I've tried fails to validate. Here's where I'm at right now with my new script: $(function() { $("#editRecord").submit(function(){ // is anything checked? if(!checkEmpty()){ $("#error").html("Please check something before submitting"); //alert("nothing Checked"); return false; } // Only A or B or C if(isAorBorC()){ $("#error").html("Please complete A or B or C, not both"); //alert("please complete A or B, not both"); return false; }; // all A's or all B's or all C's if(allAorBorCChecked()){ $("#error").html("It appears you have not completed all questions"); //alert("missing data"); return false; }; if(haveNo()){ // we're going on, but sending "type = C" } //alert("all OK"); return true; }); }); function checkEmpty(){ var OK = false; $(":radio").each(function(){ if (this.checked){ OK = true; } }); return OK; } function isAorBorC(){ var OK = false; var Achecked = false; var Bchecked = false; var Cchecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); // if we have an A checked remember it if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } if(theChar == "B" && this.checked && !Achecked){ Bchecked = true; } if(theChar == "C" && this.checked && !Achecked){ Cchecked = true; } if(Achecked && theChar == "B" && !Bchecked){ if(this.checked){ Bchecked = true; } } if(Achecked && theChar == "C" && !Cchecked){ if(this.checked){ Cchecked = true; } } if(Bchecked && theChar == "C" && !Cchecked){ if(this.checked){ Cchecked = true; } } if (Achecked && Bchecked){ OK = true; } if (Achecked && CBchecked){ OK = true; } if (Bchecked && Cchecked){ OK = true; } }); return OK; } function allAorBorCChecked(){ var notOK = false; var Achecked = false; $(":radio").each(function(){ // skip through to see if we're doing A's or B's var theChar=this.name.charAt(8); // check the A's if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } }); if(Achecked){ // set the input to A $("#type").val("A"); // check _all_ a's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "A"){ if (this.name == thisName && !thisChecked){ // Yes wasn't checked - is No? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); }elseif{ // set the input to B $("#type").val("B"); // check _all_ b's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "B"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } }else{ // set the input to C $("#type").val("C"); // check _all_ c's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "C"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } function haveNo(){ var thisName; var notOK = false; $(":radio").each(function(){ var checked = this.checked; if (this.name == thisName){ //Is this checked if(checked){ notOK = true; $("#type").val("C"); } } thisName = this.name; }); return notOK; } Anyone see what I'm doing wrong?

  • Can JAXB store the class name in the XML so that the the deserialize code doesn't need knowledge of the class?

    - by Andrew
    It seems the standard approach for deserializing JAXB XML is to specify the package name when creating the context. Then, JAXB looks up the class based on the root element: JAXBContext jc = JAXBContext.newInstance("com.foo"); Unmarshaller u = jc.createUnmarshaller(); Object o = u.unmarshal(new StringReader("...")); I'm looking for a more flexible approach where I don't have to specify the package name and could still deserialize any object. This would be as simple as JAXB storing the package in the XML, but I can't seem to find out how to do this. I can write the code to do it myself but that would be unpleasant. It would like JAXB to do it, if possible. BTW, I am not using schemas, just Annotations and marshal/unmarshal. Any ideas?

  • GCM: onMessage() from GCMIntentService is never called [migrated]

    - by Shrikant
    I am implementing GCM (Google Cloud Messaging- PUSH Notifications) in my application. I have followed all the steps given in GCM tutorial from developer.android.com My application's build target is pointing to Goolge API 8 (Android 2.2 version). I am able to get the register ID from GCM successfully, and I am passing this ID to my application server. So the registration step is performed successfully. Now when my application server sends a PUSH message to my device, the server gets the message as SUCCESS=1 FAILURE=0, etc., i.e. Server is sending message successfully, but my device never receives the message. After searching alot about this, I came to know that GCM pushes messages on port number 5228, 5229 or 5230. Initially, my device and laptop was restricted for some websites, but then I was granted all the permissions to access all websites, so I guess these port numbers are open for my device. So my question is: I never receive any PUSH message from GCM. My onMessage() from GCMIntenService class is never called. What could be the reason? Please see my following code and guide me accordingly: I have declared following in my manifest: <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="8" /> <permission android:name="package.permission.C2D_MESSAGE" android:protectionLevel="signature" /> <!-- App receives GCM messages. --> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <!-- GCM connects to Google Services. --> <uses-permission android:name="android.permission.INTERNET" /> <!-- GCM requires a Google account. --> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <!-- Keeps the processor from sleeping when a message is received. --> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="package.permission.C2D_MESSAGE" /> <uses-permission android:name="android.permission.INTERNET" /> <receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" > <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <action android:name="com.google.android.c2dm.intent.REGISTRATION" /> <category android:name="packageName" /> </intent-filter> </receiver> <receiver android:name=".ReceiveBroadcast" android:exported="false" > <intent-filter> <action android:name="GCM_RECEIVED_ACTION" /> </intent-filter> </receiver> <service android:name=".GCMIntentService" /> /** * @author Shrikant. * */ public class GCMIntentService extends GCMBaseIntentService { /** * The Sender ID used for GCM. */ public static final String SENDER_ID = "myProjectID"; /** * This field is used to call Web-Service for GCM. */ SendUserCredentialsGCM sendUserCredentialsGCM = null; public GCMIntentService() { super(SENDER_ID); sendUserCredentialsGCM = new SendUserCredentialsGCM(); } @Override protected void onRegistered(Context arg0, String registrationId) { Log.i(TAG, "Device registered: regId = " + registrationId); sendUserCredentialsGCM.sendRegistrationID(registrationId); } @Override protected void onUnregistered(Context context, String arg1) { Log.i(TAG, "unregistered = " + arg1); sendUserCredentialsGCM .unregisterFromGCM(LoginActivity.API_OR_BROWSER_KEY); } @Override protected void onMessage(Context context, Intent intent) { Log.e("GCM MESSAGE", "Message Recieved!!!"); String message = intent.getStringExtra("message"); if (message == null) { Log.e("NULL MESSAGE", "Message Not Recieved!!!"); } else { Log.i(TAG, "new message= " + message); sendGCMIntent(context, message); } } private void sendGCMIntent(Context context, String message) { Intent broadcastIntent = new Intent(); broadcastIntent.setAction("GCM_RECEIVED_ACTION"); broadcastIntent.putExtra("gcm", message); context.sendBroadcast(broadcastIntent); } @Override protected void onError(Context context, String errorId) { Log.e(TAG, "Received error: " + errorId); Toast.makeText(context, "PUSH Notification failed.", Toast.LENGTH_LONG) .show(); } @Override protected boolean onRecoverableError(Context context, String errorId) { return super.onRecoverableError(context, errorId); } }

  • How do I control output files name and content of an Hadoop streaming job?

    - by Eran Kampf
    Is there a way to control the output filenames of an Hadoop Streaming job? Specifically I would like my job's output files content and name to be organized by the ket the reducer outputs - each file would only contain values for one key and its name would be the key. Update: Just found the answer - Using a Java class that derives from MultipleOutputFormat as the jobs output format allows control of the output file names. http://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/mapred/lib/MultipleOutputFormat.htmlhttp://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/mapred/lib/MultipleOutputFormat.html I havent seen any samples for this out there... Can anyone point out to an Hadoop Streaming sample that makes use of a custom output format Java class?

  • Is there a way to prevent SQL Server silently truncating data in local variables and stored procedure parameters?

    - by Luke Woodward
    I recently encountered an issue while porting an app to SQL Server. It turned out that this issue was caused by a stored procedure parameter being declared too short for the data being passed to it: the parameter was declared as VARCHAR(100) but in one case was being passed more than 100 characters of data. What surprised me was that SQL Server didn't report any errors or warnings -- it just silently truncated the data to 100 characters. The following SQLCMD session demonstrates this: 1 create procedure WhereHasMyDataGone (@data varchar(5)) as 2 begin 3 print 'Your data is ''' + @data + '''.'; 4 end; 5 go 1 exec WhereHasMyDataGone '123456789'; 2 go Your data is '12345'. Local variables also exhibit the same behaviour: 1 declare @s varchar(5) = '123456789'; 2 print @s; 3 go 12345 Is there an option I can enable to have SQL Server report errors (or at least warnings) in such situations? Or should I just declare all local variables and stored procedure parameters as VARCHAR(MAX) or NVARCHAR(MAX)?

But in the server it is not working correctly. In the server i changed the code as below exec("http://www.mydomain.com/newtip/ffmpeg/ffmpeg -i http://www.mydomain.com/newtip/ffmpeg/videos/".$name." -ar 22050 -ab 32 -f flv -s 320x240 http://www.mydomain.com/newtip/ffmpeg/players/".$name_s.".flv"); In local I have given the Source path as C:/wamp/www/newtip/ But in server i have given the path as http://www.mydomain.com/newtip/ .I think in the server the path is wrong.
