  • BASH: Find highest numbered filename in a directory where names start with digits (ls, sed)

    - by Jake
    I have a directory with files that look like this: 001_something.php 002_something_else.php 004_xyz.php 005_do_good_to_others.php I ultimately want to create a new, empty PHP file whose name starts with the next number in the series. LIST=`exec ls $MY_DIR | sed 's/\([0-9]\+\).*/\1/g' | tr '\n' ' '` The preceding code gives me a string like this: LIST='001 002 004 005 ' I want to grab that 005, increment by one, and then use that number to generate the new filename. How do I do that in BASH?

  • java - register problem

    - by Jake
    Hi! When i try to register a person with the name Eric for example, and then again registrating Eric it works. This should not happen with the code i have. Eric should not be registrated if theres already an Eric in the list. Here is my full code: import java.util.*; import se.lth.cs.pt.io.*; class Person { private String name; private String nbr; public Person (String name, String nbr) { this.name = name; this.nbr = nbr; } public String getName() { return name; } public String getNumber() { return nbr; } public String toString() { return name + " : " + nbr; } } class Register { private List<Person> personer; public Register() { personer = new ArrayList<Person>(); } // boolean remove(String name) { // } private Person findName(String name) { for (Person person : personer) { if (person.getName() == name) { return person; } } return null; } private boolean containsName(String name) { return findName(name) != null; } public boolean insert(String name, String nbr) { if (containsName(name)) { return false; } Person person = new Person(name, nbr); personer.add(person); Collections.sort(personer, new A()); return true; } //List<Person> findByPartOfName(String partOfName) { //} //List<Person> findByNumber(String nbr) { //} public List<Person> findAll() { List<Person> copy = new ArrayList<Person>(); for (Person person : personer) { copy.add(person); } return copy; } public void printList(List<Person> personer) { for (Person person : personer) { System.out.println(person.toString()); } } } class A implements Comparator < Person > { @Override public int compare(Person o1, Person o2) { if(o1.getName() != null && o2.getName() != null){ return o1.getName().compareTo(o2.getName()); } return 0; } } class TestScript { public static void main(String[] args) { new TestScript().run(); } void test(String msg, boolean status) { if (status) { System.out.println(msg + " -- ok"); } else { System.out.printf("==== FEL: %s ====\n", msg); } } void run() { Register register = new Register(); System.out.println("Vad vill du göra:"); System.out.println("1.

  • Git on Windows: How do you set up a mergetool?

    - by Jake
    I've tried msysGit and Git on Cygwin. Both work just fine in and of themselves and both run gitk and git-gui perfectly. Now how the heck do I configure a mergetool? (Vimdiff works on Cygwin, but preferrably I would like something a little more user-friendly for some of our more... Windows-loving coworkers.) Thanks!

  • What is the delegate method that is called when an MKPinAnnotationView is touched?

    - by Jake Schwartz
    I have been searching for this all night and I have just so frustrated. When a MKPinAnnotationView is clicked, the name and the subtitle comes up. I also want to center that point on the view. I figured there was some method I had to override because the information that pops up happened without me having to code it. Hopefully this was clear enough for you all. And in the mean time, I feel like there is some hidden guide on this use of MKMaps and other classes. Either that or it is terribly documented because I am having a lot of trouble finding information. Thanks.

  • Having trouble with Regular Expression and Ampersand

    - by ajax81
    Hi All, I'm having a bit of trouble with regex's (C#, ASP.NET), and I'm pretty sure I'm doing something fundamentally wrong. My task is to bind a dynamically created gridview to a datasource, and then iterate through a column in the grid, looking for the string "A&I". An example of what the data in the cell (in template column) looks like is: Name: John Doe Phone: 555-123-1234 Email: [email protected] Dept: DHS-A&I-MRB Here's the code I'm using to find the string value: foreach(GridViewRow gvrow in gv.Rows) { Match m = Regex.Match(gvrow.Cells[6].Text,"A&I"); if(m.Success) { gvrow.ForeColor = System.Drawing.Color.Red; } } I'm not having any luck with any of these variations: "A&I" "[A][&][I]" But when I strictly user "&", the row does turn red. Any suggestions? Thanks, Dan

  • LINQ-To-SQL and Many-To-Many Relationship Deletions

    - by Jake
    I have a many-to-many relationship between two tables, let's say Friends and Foods. If a friend likes a food I stick a row into the FriendsFoods table, like this: ID Friend Food 1 'Tom' 'Pizza' FriendsFoods has a Primary Key 'ID', and two non-null foreign keys 'Friend' and 'Food' to the 'Friends' and 'Foods' tables, respectively. Now suppose I have a Friend tom .NET object corresponding to 'Tom', and Tom no longer likes pizza (what is wrong with him?) FriendsFoods ff = tom.FriendsFoods.Where(x => x.Food.Name == 'Pizza').Single(); tom.FriendsFoods.Remove(ff); pizza.FriendsFoods.Remove(ff); If I try to SubmitChanges() on the DataContext, I get an exception because it attempts to insert a null into the Friend and Food columns in the FriendsFoods table. I'm sure I can put together some kind of convoluted logic to track changes to the FriendsFoods table, intercept SubmitChanges() calls, etc to try and get this to work the way I want, but is there a nice, clean way to remove a Many-To-Many relationship with LINQ-To-SQL?

  • How to hunt down a long running request in Rails

    - by Jake
    We have a customer complaining about a long running request. I found the request in the production.log but am not sure how to dig deeper into figuring out why it took so long. Is there any artifacts in the log that I should look for? Also the DB and View times don't add up to the total request time.

  • How to convert many-to-one XML data to DataSet?

    - by TruMan1
    I have an XML document that has a collection of objects. Each object has a key/value pair of label and value. I am trying to convert this into a DataSet, but when I do ds.ReadXml(xmlFile), then it creates two columns: label and value. What I would like is to have a column for each "label" and the value to be part of the row. here is my sample of the XML: <responses> <response> <properties id="1" Form="Account Request" Date="Tuesday, March 16, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain1.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="2" Form="Account Request" Date="Tuesday, March 17, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John2</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain2.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="3" Form="Account Request" Date="Tuesday, March 18, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John3</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain3.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="4" Form="Account Request" Date="Tuesday, March 19, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain4.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> </responses> How would I convert this to a DataSet so that I can load it into a gridview with the columns: Name, Email, Website, Phone, Place of Birth, Misc, Comments, and Agree to Terms? Then row 1 would be: John, [email protected], http://domain1.com, 999-999-9999, Earth, Misc, , True How can I do this with the XML provided?

  • PHP encoding with DOMDocument

    - by Olivier Lalonde
    <tag> ????? ? </tag> When I try to get the content of the following code using DOMDocument functions, it returns something like: ÐÐ»ÐµÐºÑ Ðœ I've tried setting DOMDocument encoding to different values (UTF-8, ISO-8859-1), using mb_convert_encoding, iconv and utf8_encode but without success. How can I get "????? ?" instead of "ÐÐ»ÐµÐºÑ Ðœ" ? EDIT: The input is coming from a page loaded with curl. When I output the page content to my browser, the characters are displayed correctly (so I doubt the input is the problem).

  • How can i bundle other files when using cx_freeze?

    - by Mridang Agarwalla
    I'm using Python 2.6 and cx_Freeze 4.1.2 on a Windows system. I've created the setup.py to build my executable and everything works fine. When cx_Freeze runs it movies everything to the build directory. I have some other files that i would like included in my build directory. How can i do this? Here's my structure. src\ setup.py janitor.py README.txt CHNAGELOG.txt helpers\ uncompress\ unRAR.exe unzip.exe Here's my snippet: setup ( name='Janitor', version='1.0', description='Janitor', author='John Doe', author_email='[email protected]', url='http://www.this-page-intentionally-left-blank.org/', data_files = [ ('helpers\uncompress', ['helpers\uncompress\unzip.exe']), ('helpers\uncompress', ['helpers\uncompress\unRAR.exe']), ('', ['README.txt']) ], executables = [ Executable\ ( 'janitor.py', #initScript ) ] ) I can't seem to get this to work. Do i need a MANIFEST.in file? Thank you.

  • Recursion problem in C

    - by jake
    Hi there. I've been trying to solve this problem for a few days now but it seems I haven't grasped the concept of recursion,yet. I have to build a program in C (recursion is a must here but loops are allowed as well) which does the following: The user inputs 2 different strings.For example: String 1 - ABC String 2 - DE The program is supposed to print strings which are combined of the ones the user has entered. the rule is that the inner order of the letters in each string (1&2) must remain. That's the output for string1=ABC & string2=DE ": abcde abdce abdec adbce adbec adebc dabce dabec daebc deabc If anyone could give me a hand here, it would be great. Thanks guys.

  • How to display multiple cell entries individually from a MySQL database and using PHP

    - by Jake
    I have a column called post_tags where there is sometimes one tag entry and sometimes multiple tags stored. These are separated by * symbols. I want to display these out to the screen one by one. If there were just one item inside the cell I would have used: $query = mysql_query("SELECT post_tags FROM posts WHERE id=$id"); while ($result = mysql_fetch_assoc($query)) { $result['post_tags']; } But how can I display each entry individually when there are multiple ones in one cell (is this what the explode function is for)?

Any pointers or samples are really appreciated! p.s : In the actual file, there are 10 sets of contacts going from left to right and there are few thousand such records. It is a CSV file and I loaded into MySQL to manipulate the data.

  • one page filter results in new page in javascript

    - by Jake
    I have links set up on one page and the relationship between the links is a parent child relationship. (For example: Parent: All, Children: Software; Hardware) These links of course lead the user to a new page that shows the results from a table that is populated. Currently these links are all Similar destinations, but just a filter in the url. But the problem is that there is a javascript filter on the page that gives the user to choose between All, Software, or Hardware. Understand basically that if the url is still reading that there on the software page but they just filtered on the page to be Hardware that doesn't look good IMO. So what I was trying to do was make the links on the inital page all go the the exact same destination and somehow still know on the new page which link was clicked and run the javascript filter from knowing which link was clicked on that page. Is there a way to found that out from javascript? I guess a way to pass that value to the new page and retrieving it in javascript without showing it in the url so I can filter the table for the user based on that value?

  • Can MySQL Nested Select return list of results

    - by John
    Hi I want to write a mysql statement which will return a list of results from one table along with a comma separated list of field from another table. I think an example might better explain it Table 1 ======================== id First_Name Surname ---------------------- 1 Joe Bloggs 2 Mike Smith 3 Jane Doe Table 2 ======================== id Person_Id Job_id --------------------- 1 1 1 2 1 2 3 2 2 4 3 3 5 3 4 I want to return a list of people with a comma separated list of job_ids. So my result set would be id First_Name Surname job_id ------------------------------ 1 Joe Bloggs 1,2 2 Mike Smith 2 3 Jane Doe 3,4 I guess the sql would be something like select id, First_Name, Surname, (SELECT job_id FROM Table 2) as job_id from Table 1 but obviously this does not work so need to change the '(SELECT job_id FROM Table 2) as job_id' part. Hope this makes sense Thanks John

  • Working with ieee format numbers in ARM

    - by Jake Sellers
    I'm trying to write an ARM program that will convert an ieee number to a TNS format number. TNS is a format used by some super computers, and is similar to ieee but different. I'm trying to use several masks to place the three different "part" of the ieee number in separate registers so I can move them around accordingly. Here is my unpack subroutine: UnpackIEEE LDR r1, SMASK ;load the sign bit mask into r1 LDR r2, EMASK ;load the exponent mask into r2 LDR r3, GMASK ;load the significand mask into r3 AND r4, r0, r1 ;apply sign mask to IEEE and save into r4 AND r5, r0, r2 ;apply exponent mask to IEEE and save into r5 AND r6, r0, r3 ;apply significand mask to IEEE and save into r6 MOV pc, r14 ;return And here are the masks and number declarations so you can understand: IEEE DCD 0x40300000 ;2.75 decimal or 01000000001100000000000000000000 binary SMASK DCD 0x80000000 ;Sign bit mask EMASK DCD 0x7F800000 ;Exponent mask GMASK DCD 0x007FFFFF ;Significand mask When I step through with the debugger, the results I get are not what I expect after working through it on paper. EDIT: What I mean, is that after the subroutine runs, registers 4, 5, and 6 all remain 0. I can't figure out why the masks are not working. I think I do not fully understand how the number is being stored in the register or using the masks wrong. Any help appreciated. If you need more info just ask. EDIT: entry point: Very simple, just trying to get these subroutines working. ENTRY LDR r1, IEEE ;load IEEE num into r1 BL UnpackIEEE ;call unpack sub SWI SWI_Exit ;finish

  • Threading is slow and unpredictable?

    - by Jake
    I've created the basis of a ray tracer, here's my testing function for drawing the scene: public void Trace(int start, int jump, Sphere testSphere) { for (int x = start; x < scene.SceneWidth; x += jump) { for (int y = 0; y < scene.SceneHeight; y++) { Ray fired = Ray.FireThroughPixel(scene, x, y); if (testSphere.Intersects(fired)) sceneRenderer.SetPixel(x, y, Color.Red); else sceneRenderer.SetPixel(x, y, Color.Black); } } } SetPixel simply sets a value in a single dimensional array of colours. If I call the function normally by just directly calling it it runs at a constant 55fps. If I do: Thread t1 = new Thread(() => Trace(0, 1, testSphere)); t1.Start(); t1.Join(); It runs at a constant 50fps which is fine and understandable, but when I do: Thread t1 = new Thread(() => Trace(0, 2, testSphere)); Thread t2 = new Thread(() => Trace(1, 2, testSphere)); t1.Start(); t2.Start(); t1.Join(); t2.Join(); It runs all over the place, rapidly moving between 30-40 fps and sometimes going out of that range up to 50 or down to 20, it's not constant at all. Why is it running slower than it would if I ran the whole thing on a single thread? I'm running on a quad core i5 2500k.

  • Where do I subclass SC.Record?

    - by Jake
    I'm using SproutCore and going through the Todos tutorial on http://wiki.sproutcore.com/Todos+06-Building+with+Rails. SproutCore and Rails use different names for the primary key on a model (Sproutcore = 'guid', Rails = 'id'). The tutorial gives directions to Adjust Rails JSON output, but in my app that I'm planning on building, I cannot do this because sproutcore is only one of a couple interfaces used to interact with the Rails app. As an alternate option, the tutorial gives the following directions: Option 2: Set primaryKey in your Sproutcore model class You can subclass SC.Record and set the primaryKey of your sublcass to "id". Your Todo- Object then needs to extend from e.g. App.Rails.Record. App.Rails.Record = SC.Record.extend({ primaryKey : "id" // Extend your records from App.Rails.Record instead of SC.Record. }); Where should I subclass SC.Record (i.e. in what file) such that it is properly read and included?

  • Adding text before footer in wordpress

    - by jake
    I've been reading the wordpress codex and it seems that if I want to add some text just before the footer shows up I should use code like this in my functions.php add_action('wp_footer', 'your_function'); function your_function() { $content = 'This is inserted at the bottom'; echo $content; } It is my understanding that the $content should show up just before the footer, but it does not show up at all. Is there another way to show up my code just before the footer ? I am with WP 2.8 but this should not matter

  • Want to load jquery dialog from a different web-page

    - by Jake
    I'm a bit of a n00b with jquery so this one is probably an RTFM question: I'm writing an application to create a somewhat complex record for my client. Building the record requires doing a couple of server side searches inside a dialog. Right now I have everything framed up in 1 file (asp.net) and it's ok. But I can see as I add the business logic and the communication with the server this is going to get really ugly. I'm alreay putting most of the javascript in external files, but I'd like to move the HTML for the dialogs out too. How do I get the jquery dialog method to load the dialog body from the html files? Something like: getDialogHTML(dialogHolderDiv); <---magic goes here var dialogOptions = { ... }; $("#"+dialogHolderDiv).dialog(dialogOptions); $("#"+dialogHolderDiv).dialog('open'); any help will be apperciated .
