• Twitter Search API Question

  - by supermogx

  I'm using the twitter search API to get twitter posts based on some keywords, using AND and OR keyword. It works OK, but I seem to get problems using hashtags... For example : Not returning any results : http://search.twitter.com/search.json?q="%23ipad+AND+%23ipod"+OR+"%23joke+AND+%23funny"&rpp=100&callback=? Returning results : http://search.twitter.com/search.json?q="ipad+AND+ipod"+OR+"joke+AND+funny"&rpp=100&callback=? But there's results with #ipod AND #ipad because when I search only for #ipod, I can see a lot of posts with both hashtags. Example : http://search.twitter.com/search.json?q=%23ipad&rpp=100&callback=? P.S. %23 = # Any idea?

• Complex orderby question (entity framework)

  - by PFranchise

  Ok, so I will start by saying that I am new to all this stuff, and doing my best to work on this project. I have an employee object, that contains a supervisor field. When someone enters a search on my page, a datagrid displays employees whose name match the search. But, I need it to display all employees that report to them and a third tier of employees that report to the original employee's underlings. I only need three tiers. To make this easier, employees only come in 3 ranks, so if rank==3, that employee is not in charge of others. I imagine the best method of retrieving all these employees from my employee table would be something like from employee in context.employees where employee.name == search || employee.boss.name == search || employee.boss.boss.name == search But I am not sure how to make the orderby appear the way I want to. I need it to display in tiers. So, it will look like: Big Boss Boss underling underling Boss underling Boss Boss Big Boss Like I said, there might be an easier way to approach this whole issue, and if there is, I am all ears. Any advice you can give would be HIGHLY appreciated.

• SVN Merge Question

  - by SVN

  Suppose that I have two massive folders in SVN: test and prod. I'm trying to use the following svn command to merge the content from test into prod: svn merge ./prod@HEAD ./test@HEAD ./prod However, my SVN repository is huge and this process takes an enormous amount of time. Is there any way that I can make a simpler merge statement which will be more processor friendly? Perhaps a server-URL based merge? Any insight is appreciated....

• MySQL: Question about SELECT WHERE AND/OR

  - by Andrew

  I'm trying to write a query that returns the same result from three different events, but I think I am doing it wrong. I can run my query against one event ID and it works. How can I select all three? Here's what I have so far: SELECT * FROM `Registrations` WHERE `Role` = "Attendee" AND `RegistrationStatus_ID` = "1" AND `DigSignature` IS NULL AND `Event_ID` = "147" OR `Event_ID` = "155" OR `Event_ID` = "160"

  - by Adam Outler

  Hello, I am new at java. I am doing the following: Read from file, then put data into a variable. checkToken = lineToken.nextToken(); processlinetoken() } But then when I try to process it... public static void readFile(String fromFile) throws IOException { BufferedReader reader = new BufferedReader(new FileReader(fromFile)); String line = null; while ((line=reader.readLine()) != null ) { if (line.length() >= 2) { StringTokenizer lineToken = new StringTokenizer (line); checkToken = lineToken.nextToken(); ...... But here's where I come into a problem. public static void processlinetoken() checkToken=lineToken.nextToken(); } it fails out. Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method nextToken() is undefined for the type String at testread.getEngineLoad(testread.java:243) at testread.readFile(testread.java:149) at testread.main(testread.java:119) so how do I get this to work? It seems to pass the variable, but nothing after the . works.

• PHP preg_replace - Very quick question

  - by RC

  Masters of regular expressions, please help! See this string: $string = "http://www.url.com/?fieldA=123&fieldB=456&fieldC=789"; Assuming "fieldB" always has a positive non-decimal numerical value (but not necessarily three digits long), what preg_replace command do I need to remove it completely, such that the string will then read: $string = "http://www.url.com/?fieldA=123&fieldC=789"; Thanks!

• Django and a referrer system question

  - by Hellnar

  Hello, I am trying develop a basic referrer system to my Django website, system will be generating a unique url for each users to share with their friends. Once these friends enter this website, system somehow keep the data that "this user is browsing by the reference of X user" and once this invited person decided to register for an account, system will save this information (maybe as an extra Foreign Key of the inviting user in the UserProfile model) Now how can I keep track of the inviting user from the moment entering using the referred link to the point where he/she registers to the site. Would session framework work on this? If not how could this be done ?

• Statistics Question: Kernel Smoothing in R

  - by James Thompson

  I have data of this form: x y 1 0.19 2 0.26 3 0.40 4 0.58 5 0.59 6 1.24 7 0.68 8 0.60 9 1.12 10 0.80 11 1.20 12 1.17 13 0.39 I'm currently plotting a kernel-smoothed density estimate of the x versus y using this code: smoothed = ksmooth( d$resi, d$score, bandwidth = 6 ) plot( smoothed ) I simply want a plot of the x versus smoothed(y) values, which is ## Heading ## However, the documentation for ksmooth suggests that this isn't the best kernel-smoothing package available: This function is implemented purely for compatibility with S, although it is nowhere near as slow as the S function. Better kernel smoothers are available in other packages. What other kernel smoothers are better can these smoothers be found?

• C++: Trouble with Pointers, loop variables, and structs

  - by Rosarch

  Consider the following example: #include <iostream> #include <sstream> #include <vector> #include <wchar.h> #include <stdlib.h> using namespace std; struct odp { int f; wchar_t* pstr; }; int main() { vector<odp> vec; ostringstream ss; wchar_t base[5]; wcscpy_s(base, L"1234"); for (int i = 0; i < 4; i++) { odp foo; foo.f = i; wchar_t loopStr[1]; foo.pstr = loopStr; // wchar_t* = wchar_t ? Why does this work? foo.pstr[0] = base[i]; vec.push_back(foo); } for (vector<odp>::iterator iter = vec.begin(); iter != vec.end(); iter++) { cout << "Vec contains: " << iter->f << ", " << *(iter->pstr) << endl; } } This produces: Vec contains: 0, 52 Vec contains: 1, 52 Vec contains: 2, 52 Vec contains: 3, 52 I would hope that each time, iter->f and iter->pstr would yield a different result. Unfortunately, iter->pstr is always the same. My suspicion is that each time through the loop, a new loopStr is created. Instead of copying it into the struct, I'm only copying a pointer. The location that the pointer writes to is getting overwritten. How can I avoid this? Is it possible to solve this problem without allocating memory on the heap?

• Sharepoint connected web parts question

  - by philj

  I have one web part (the provider) which displays insurance claims in a gridview. When user clicks on one this value(case number) is passed via IWebPartField interface to another web part(consumer) which displays detailed info about the claim. So far so good. I can select different claims in the provider and the details show up in the consumer just fine. The moment I add a TextBox to the consumer, the consumer no longer recognizes the case number passed. I need the user to be able to enter a value in the textbox and click a button to update that claim info. I can debug and attach to process and it looks like it is getting the case in the callback function, etc, but when it is setting parameters for the stored proc in CreateChildControls, it is null. Comment out the TextBox and it works fine. Any clues as to what is going on? Brand new to Sharepoint web parts...any help appreciated! thanks, PhilJ

• HTML5 Canvas compositing question (source-in)

  - by Alex Ciarlillo

  I am trying to recreate a page flipping type animation in HTML5 using canvas. The animation is based on ideas from here: hxxp://oreilly.com/javascript/archive/flashhacks.html but thats not really important. The problem I am having is that using the 'source-in' composite operation is not giving me the results I expect and would like clarification as to why. Here is the example: (i think it can only be viewed in chrome, not working in FF 3.6) http://acpound.fylez.com/test/example.html The black rectangle is supposed to act as a 'mask' for the page being turned over. All I want to see is the turning page in the areas where it overlaps the mask. The problem is the entire black rectangle is drawn, not just the area where they overlap. The source is all on the page. I know HTML5 isn't really being used yet, I'm just experimenting for my personal site and curiosity. Any ideas would be greatly appreciated.

• Newbie question attribute from associated table not showing up in index view

  - by Lauren

  Hi I know this is something simple I am doing wrong. I have three tables, installation, neighborhood, schools Installation: has_many :schools has_many :neighborhoods Neighborhood: has_many :installations has_many :schools Schools: belongs_to :installations belongs_to :neighborhoods I can't figure out how to show the name of the neighborhood the school is located in on the index view. I can get it to show on the show view once I have the school id. But on the index view I can't figure out what to put in the controller that will allow me to access the neighborhood name from the neighborhood_id that is in the School model. I am sure this is so easy and I am screwing up something stupid. HELP!

• Design question - loading info from DB

  - by eriks

  I need to build a class that will represent a row in some table in DB (lets say the table is 'Subscriber' and so is the class). I can have the class Subscriber which constructor receives the Objectkey of subscriber, retrieves info from DB and initializes its members. I add another class - SubscriberLoader which have a static method 'LoadSubscriber'. This method will receive the subscriber objectkey, retrieve info from DB, crate a Subscriber object and initialize its members. Subscriber constructor will be private and SubscirberLoader will be friend class of Subscriber - this way, client could build a Subscriber only using the loader. which of the two in better? any other suggestions?
