  - by The Learner

  I have string like: This.is.a.great.place.too.work. (or) This/is/a/great/place/too/work/ than my java program should give me that the sentence is valid and it has "work". if i Have : This.is.a.great.place.too.work.hahahha (or) This/is/a/great/place/too/work/hahahah Should not give me that there is a work in the sentance. so I am looking at java strings to find a word at the end of the sentance having . (or),(or)/ before it. How can I achieve that

• Low-overhead way to access the memory space of a traced process?

  - by vovick

  Hello all. I'm looking for an efficient way to access(for both read and write operations) the memory space of my ptraced child process. The size of blocks being accessed may vary from several bytes up to several megabytes in size, so using the ptrace call with PTRACE_PEEKDATA and PTRACE_POKEDATA which read only one word at a time and switch context every time they're called seems like a pointless waste of resources. The only one alternative solution I could find, though, was the /proc/<pid>/mem file, but it has long since been made read only. Is there any other (relatively simple) way to do that job? The ideal solution would be to somehow share the address space of my child process with its parent and then use the simple memcpy call to copy data I need in both directions, but I have no clues how to do it and where to begin. Any ideas?

• MATLAB: Designing a "Warm Start"

  - by squall14414

  I'm currently coding a function in MATLAB that has two steps: It processes some data It does some calculations on the processed data I'm using the function to run a series of experiments, where I tweak the way calculations occur in step 2). Seeing how I'm working with a large dataset and the data processing step takes a while each time, however, I'm wondering whether there is anyway to code in a "warm start" in the function. That is to say, is there anyway to save all the progress that I've done after step 1) so that if I run the function a second or third time, it can skip step 1) and go right to step 2)?

• client-side vs server-side

  - by amalafrida

  In general, should one design in order to place processing load on client-side? More specifically, a search engine to locate subscriber information requires a fair amount of parsing (multiple phone numbers to sort and format, hour of day, timezone, comparisons for possible substitutions of user information, etc.). Again, in general, is it preferred that one have client-side do the work? It seems to me 'yes' in a situation in which one will have many thousands of hits per minute. Use php for quick database queries ... process retrieved data client-side. yes ... no?

• Can the LibreOffice LightProof grammar library be used externally?

  - by Phyxx

  LibreOffice 3.5 includes a grammar checker, called (or maybe based on) LightProof. From what I have read, LightProof seems to be a Python library that can be used to check for custom grammar rules. But I can not for the life of me find a project page for LightProof. The closest I got was http://cgit.freedesktop.org/libreoffice/lightproof/tree/, which seems to be the code for the LibreOffice extension, not LightProof itself. So is LightProof actually a library that can be implemented in other applications, or is it just a code word for a LibreOffice feature?

• Compilation failing - no #include - boost

  - by jwoolard

  Hi, I'm trying to compile a third-party library, but g++ is complaining about the following line: typedef boost::shared_ptr<MessageConsumer> MessageConsumerPtr; The strange thing is, there is no #include directive in the file - and it is clearly supposed to be this way; there are about 60 files with the same (or very similar) issues. Clearly if there was an #include directive referencing the relevant boost header this would compile cleanly. My question is: how can I get g++ to somehow automagically find the relevant symbol (in all instances of this issue, it is a namespace that can't be found - usually std:: or boost::) by either automatically processing the relevant header (or some other mechanism). Thanks. Edit My current g++ call looks like: g++ -fPIC -O3 -DUSING_PCH -D_REENTRANT -I/usr/include/boost -I./ -c MessageInterpreter.cpp -o MessageInterpreter.o

• SQL Server FTS: possible to get information how/why rows were matched?

  - by jimmy_keen

  Is it possible to get the information why/how given row returned by FTS query was matched (or which substring caused row to match)? For example, consider simpliest table with id and text columns, with FTS index on the later one. SELECT * FROM Example WHERE CONTAINS(text, 'FORMSOF(INFLECTIONAL, jump)'); This examplary query could return, say row {1, 'Jumping Jack'}. Now, is it possible to somehow get information that this very row was matched because of 'Jumping' word? It doesn't even have to be exact information, more of a which substring caused row to match. Why I'm asking - I got C# app that builds up those queries basing on user input (keywords to search for), and I need the very basic information why/how row was matched back, to use further in C# code. If it's not possible, any alternatives?

• Java - Count words in two documents

  - by user552961

  Good Morning - it is school assignment, I am not asking for any source code (if you can provide any pesudo code it would be awesome). Here is the problem :( I have to create a term frequency table. It is not pure TF, I just need to count the words and write down. I know basic steps to do it 1 - extract all terms (I can do it with file reader) 2 - remove repeating terms (I can do it with TreeMap) The output of 2nd step would be Niga, ponga, dinga, bitlo, etc. 3 - Now I have to see if there is any word in current file from above terms or not, if yes then I will count. Now this is my problem, I stucked on step 3 :( I have some idea how to count words with TreeMap (treemap.containskey etc.) but it would be global count not local count for each file :( Any pseudo code?

• [C++] Simple inheritance question

  - by xbonez

  I was going over some sample questions for an upcoming test, and this question is totally confusing me. Any help would be appreciated. Consider the following code: class GraduateStudent : public Student { ... }; If the word "public" is omitted, GraduateStudent uses private inheritance, which means which of the following? GraduateStudent objects may not use methods of Student. GraduateStudent does not have access to private objects of Student. No method of GraduateStudent may call a method of Student. Only const methods of GraduateStudent can call methods of Student.

• Server Side code Pushing Data to client Browser while current thread is busy Comet (programming)

  - by h_power11

  Hello Friends, I am writing one simple web page with bunch of textboxes and a button control. Now when user finished editing the values on this text boxes user has to click the button and this button invoke heavily process intensive algorithm on server side code based on the data received from client (Textboxes) And it could some time takes up to 30 to 45 minutes to complete the whole operation so the current thread is still inside the button click event handler function. That background task only provides one event, and the web page subscribes to it to get some text data after each stage of processing I was wandering if there is any way I can keep user up-to-date with what is the current progress on that background task. I have div element to print the current status information So I am looking for some sort of reverse mechanism then "get" and "post". I have read some articles on the Comet (programming) but I can't find any easy or definitive answer Thanks in advance

• Getting an Ajax response from Zend Framework Controller

  - by JavaLava

  I'm doing an Ajax request on one of my views to a Controller but I am unable to send back a response to the Ajax method. In the snippet below, I am trying to send the word 'hellopanda' back but in the alert message, I'll get data as an object. View : $.ajax({ type: "POST", url: "localhost/some-activity", data: dataString, success: function(data) { alert( "Data is: " + data); //do something with data }, error: function(data){ alert( "Data is: " + data); //do something with data }, onComplete: function(){ } }); Controller: public function someActivityAction(){ //do stuff echo "hellopanda"; } I'm pretty sure the echo is the problem. Any insights on to how to do a proper response to the view would be greatly appreciated.

• Example applications and benefits of using "C" , "C++" or "Java"

  - by Waltzy

  Ok, I'm revising for my upcoming year 2 exams on a CS course and its likely something like this will come up. my question is what is an ideal application that would especially benefit from the program features of each of the three languages? I have a vague idea but getting a second opinion could really help. JavaPortability, easy - good for GUIs. C++Fast but may requite significant changes in order to be moved from system to system, good for image processing. CI'm unsure here small embedded applications? Some clarification on this would be really appreciated, thanks again StackOverflow

• Methods for breaking up content client-side into multiple "pages"

  - by Tom Genoni

  I have a long HTML text-only article formatted with paragraph tags. What I'd like to do is break this content into N number of divs so that I can create individual pages. So, for instance, on an iPad/iPhone, instead of reading one long page the user could swipe right/left to navigate to pages. My initial javascript attempts have been somewhat convoluted: creating an array of the text, measuring line-heights, device window heights, adding closing/opening paragraph tags and the end/beginning of pages. Thoughts on a good way to approach this? I will not have access to server-side processing, this has to be a client-side solution.

• MySQL: How to separate a name field in one table into firstname / lastname in two separate tables?

  - by Eileen

  I have a drupal database where the node table is full of profiles. The field node.title is "Firstname Lastname". I want to separate the names so that node.title = "Firstname", and over in another table entirely, content_type_profile.field_lastname_value = "Lastname". The entries in the two tables can be joined on the field nid. I'd love to run a SQL command to do this, and I am fine with taking the naive approach that the first word is the first name, and everything else in the field is last name -- it will mean a few manual corrections down the line, but that's much better than doing it all by hand in the first place. (I read this question and surely the answer lies in there but I am not that SQL-savvy and am not sure how to make it work for my database.) Thanks!

• A way to search form table in MySQL database.

  - by Eugene

  I looked for a way to scan database for a specific table. For example i have: Database: system_ultimate Table: system_settings And let us say, that one doesn't know precise name of the table. He only knows, that it is some how connected to word settings. How could he search for that table name then? I understand, that usually people who develop know, what they develop, but I'm trying to get hang of MVC and I'm trying to stay as far away as possible from direct communication with table using the name. I know, that to see all tables I could use SHOW TABLES;

• Visual Studio C++ adds "junk" to my programs

  - by sub

  I have looked into the binaries produced by MSVC 2010 from my source code, and saw everything being filled with "junk". I don't know how to explain, but my executables are being added too much unnecessary information, like: Lots of Microsoft default error messages, I don't want them XML schema settings (Why!?) Other things not important for the execution of the main program How can I stop MSVC doing this? Do I have to switch to GCC? In all other programs (written in C++ too, from Word processors to games), this junk simply doesn't exist.

• Access to related Objects inside a model propery

  - by aliem

  Hi, I just run into some problems with django models. Example code is better than any word: class Cart(models.Model): updated_at = models.DateTimeField(auto_now=True) created_at = models.DateTimeField(auto_now_add=True) def __unicode__(self): return u'date %s;'%(self.created_at) def __str__(self): return self.__unicode__() def _total_items(self): """ Totale n di oggetti """ a = 0 for i in self.items.all: a += i.quantity return a total_items = property(_total_items) class Item(models.Model): cart = models.ForeignKey(Cart) quantity = models.PositiveIntegerField() def __unicode__(self): return u'product %s'%(self.id) def __str__(self): return self.__unicode__() but, when i call the cart property here's what i get in the python console: >>> a.total_items Traceback (most recent call last): File "<console>", line 1, in <module> File "models.py", line 49, in _total_items for i in self.item_set.all: TypeError: 'RelatedManager' object is not callable

• PHP: reusing database class

  - by citricsquid

  Hi, I built a class that allows me to do: $db->query($query); and it works perfectly, although if I want to do: $db->query($query); while($row = $db->fetch_assoc()){ $db->query($anotherquery); echo $db->result(); } it "breaks" the class. I don't want to constantly have to redeclare my class (eg: $seconddb = new database()), is there a way to get around this? I want to be able to reuse $db within $db, without overwriting the "outside" db. currently I'm create an array of data (from db-fetch_assoc() then doing a foreach and then doing the db call inside that: $db->query('SELECT * FROM table'); while($row = $db->fetch_assoc()){ $arr[] = $row; } foreach($arr as $a){ $db->query(); // query and processing here } Is this the best method or am I missing the obvious? Should I consider passing a connection link ID with the database connection?

• Why are my Lucene Document results empty?

  - by vegashacker

  I'm running a simple test--trying to index something and then search for it. I index a simple document, but then when a search for a string in it, I get back what looks to be an empty document (it has no fields). Lucene seems to be doing something, because if I search for a word that's not in the document, it returns 0 results. Any reason why Lucene would reliably return a document when it finds one that matches the given query, and yet that document has nothing in it? Thanks! PS: I'm actually running Lucandra (Lucene + Cassandra). That certainly may be a relevant detail, but not sure.

• How to post private message with Twitter API

  - by Venil Aminovich

  I want to send a private message to my followers with Twitter API (application is for iPhone). If I can do that with this API, please, give the code or the link to the code to me. Update: I've read the link dev.twitter.com/docs/api/1/post/direct_messages/new ACB gave me, and I understood the idea, how post direct messages. But the issue is there is no any word about autentification in this link. But I can't post tweet without autentification. Should I use TWRequest and set the account to this request? Thank you in advance!

• DataTable from TextFile?

  - by Craig

  I have taken over an application written by another developer, which reads data from a database, and exports it. The developer used DataTables and DataAdaptors. So, _dataAdapter = new SqlDataAdapter("Select * From C....", myConnection); and then ExtractedData = new DataTable("CreditCards"); _dataAdapter.Fill(ExtractedData); ExtractedData is then passed around to do different functions. I have now been told that I need to, in addition to this, get the same format of data from some comma separated text files. The application does the same processing - it's just getting the data from two sources. So, I am wondering if I can get the data read into a DataTable, as above, and then ADD more records from a CSV file. Is this possible?

• case sensititivity with users controller on certain hosting

  - by Leo

  We generally use two different hosting services. On one, everything works ticketyboo, as it does on my local dev servers. On the other server, however, I am having this problem: I can't access the users controller like this: http://www.example.com/users/login But I can like this: http://www.example.com/Users/login ** note the capitalised 'Users' ** If I displace the application to a sub-folder everything works fine (both upper- and lowercase). The hosting company have looked at it and can't see a problem at their end and they assure me that users is not a reserved word. You might say this isn't a problem, just use the version that works. Unfortunately it leads to problems downstream where Cake core starts generating urls itself. Anybody else seen this problem or know the solution? [This only occurs on the users controller - all others work as expected]

• UI: where to display a status result from a drag & drop?

  - by Jason S

  So I've got drag & drop working. When a drop occurs, I do some processing, and sometimes there is a result that I want to make the user aware of. Right now I am just outputting to the console which isn't very nice. What's an appropriate way to display a status result from a drag & drop? Somehow a modal dialog box seems inappropriate, and a status bar is too space-constrained, I think.
