  • Need help finding a good curriculum/methodology for self-teaching to program from scratch

    - by BrotherGA2
    My friend and I have both dedicated ourselves to learning the essentials of programming by June of this year from nearly no programming experience. I have done some research and have come to the conclusion that using the Python language will be the best for us, but I am open to suggestions with good reasoning behind them. My motives for learning programming are: Potential Career Path to be able to create programs that can: solve problems; entertain, i.e. useful applications and games. Online college lectures + book (which I am willing to purchase) sounds like a good combination, but I do not know which would be most suitable for me. tl;dr: What I would like to find from the excellent people here is the following: a good, potentially best, programming course and/or book that is well structured and uses good pedagogy so that a person dedicated to learn programming may do so by following its curriculum (or use it to develop a curriculum) over the course of a few months. Thanks! (I apologize if this type of question is not considered proper etiquette, but I haven't found a consensus on this, and would like some guidance beyond the research I've already done)

  • Time Machine for Windows?

    - by Blub
    Finally got convinced to start using some kind of version control for my code instead of zipping down a copy of the project at the end of each day. Downloaded Tortoise SVN and used it to create a repository localy on my hdd. I've been using it for 2 days now but I have to say that using it is actually more hassle than just copying the project manually in explorer. Sure, you only store incremental changes but with the cheap disks of today I can't really say that's an argument when you only have small projects. I haven't realy found a quick way to browse the older versions of my files eighter. What I want is an infinite undo that is completely transparent while I code, if I save the file I want a backup. I don't want to check out, check in and don't even get me started on moving files. I haven't tried Time Machine for OS X but it looks like it's exactly what I'm looking for. Does such a program exist for windows? Preferably free and with some kind of tagging-system so I can tag a timestamp when the project is working etc. Maybe should add that I mostly work alone on a single computer. Update: Some of you asked why I want backup. Since I work alone it's mostly to allow me to quickly hack up a solution without worrying that something will screw up.

  • Uninitialized array offset

    - by kimmothy16
    Hey everyone, I am using PHP to create a form with an array of fields. Basically you can add an unlimited number of 'people' to the form and each person has a first name, last name, and phone number. The form requires that you add a phone number for the first person only. If you leave the phone number field blank on any others, the handler file is supposed to be programmed to use the phone number from the first person. So, my fields are: person[] - a hidden field with a value that is this person's primary key. fname[] - an input field lname[] - an input field phone[] - an input field My form handler looks like this: $people = $_POST['person'] $counter = 0; foreach($people as $person): if($phone[$counter] == '') { // use $phone[0]'s phone number } else { // use $phone[$counter] number } $counter = $counter + 1; endforeach; PHP doesn't like this though, it is throwing me an Notice: Uninitialized string offset error. I debugged it by running the is_array function on people, fname, lname, and phone and it returns true to being an array. I can also manually echo out $phone[2], etc. and get the correct value. I've also ran is_int on the $counter variable and it returned true, so I'm unsure why this isn't working as intended? Any help would be great!

  • Best way to display a "High Scores" Results

    - by George
    First, I would to thank everyone for all the help they provide via this website. It has gotten me to the point of almost being able to release my first iPhone app! Okay, so the last part I have is this: I have a game that allows users to save their high scores. I update a plist file which contains the users Name, Level, and score. Now I want to create a screen that will display the top 20 high scores. What would be the best way to do this? At first I thought possibly creating an HTML file with this info but am not even sure if that is possible. I would need to read the plist file, and then write it out as HTML. Is this possible? To write a file out as HTML? Or an even better question, is there a better way? Thanks in advance for any and all help! Geo...

  • Spaceship objects

    - by Jam
    I'm trying to make a program which creates a spaceship and I'm using the status() method to display the ship's name and fuel values. However, it doesn't seem to be working. I think I may have messed something up with the status() method. I'm also trying to make it so that I can change the fuel values, but I don't want to create a new method to do so. I think I've taken a horrible wrong turn somewhere in there. Help please! class Ship(object): def __init__(self, name="Enterprise", fuel=0): self.name=name self.fuel=fuel print "The spaceship", name, "has arrived!" def status(): print "Name: ", self.name print "Fuel level: ", self.fuel status=staticmethod(status) def main(): ship1=Ship(raw_input("What would you like to name this ship?")) fuel_level=raw_input("How much fuel does this ship have?") if fuel_level<0: self.fuel=0 else: self.fuel(fuel_level) ship2=Ship(raw_input("What would you like to name this ship?")) fuel_level2=raw_input("How much fuel does this ship have?") if fuel_level2<0: self.fuel=0 else: self.fuel(fuel_level2) ship3=Ship(raw_input("What would you like to name this ship?")) fuel_level3=raw_input("How much fuel does this ship have?") if fuel_level3<0: self.fuel=0 else: self.fuel(fuel_level3) Ship.status() main() raw_input("Press enter to exit.")

  • php - sort and delete duplicates?

    - by c41122ino
    I've got an array that looks like this: Array ( [0] => Array ( num => 09989, dis => 20 ) [1] => Array ( num => 09989, dis => 10 ) [2] => Array ( num => 56676, dis => 15 ) [3] => Array ( num => 44533, dis => 20 ) [4] => Array ( num => 44533, dis => 50 ) ) First, I'm trying to sort them by num, and can't seem to get the usort example from php.net working here. It simply doesn't appear to be sorting... I'm also trying to delete the array element if it's a duplicate and whose dis value is higher than the other one. So, based on the example above, I'm trying to create: Array ( [0] => Array ( num => 09989, dis => 10 ) [1] => Array ( num => 44533, dis => 20 ) [2] => Array ( num => 56676, dis => 15 ) ) This is the code from php.net: function cmp($a, $b) { if ($a == $b) { return 0; } return ($a < $b) ? -1 : 1; }

  • ASP Menu driving me insane

    - by simplesimon
    Hi there, I am trying to create a menu using ASP (I have never used ASP before, im a PHP man) using values stored in a database. basically the html layout i want is as such: <ul> <li> <ul class="sub-menu"> <li class="sub-menu-li">Test</li> </ul> </li> </ul> I need to loop around the root menu items rs("AD_Level") which is equal to 0 for root objects, then inside that loop, lop around anything that has the same parent id eg if the current record is AD_Level =0 and AD_Parent=5 then loop around all items with AD_Parent 5 and AD_Level != 0 and insert the values into html and so on and so forth. Please help! I am struggling with a new language and cannot see a way to do this without losing sanity Edit (Extracted from Comment by OP) while not rsAdmin.eof sPar = rsAdmin("ad_parent" if rsAdmin("AD_Level")=0 then while not rsAdmin2.eof if rsAdmin2("AD_Level")<>0 and rsAdmin2("ad_parent")=sPar and rsAdmin2("AD_Sec_Level")=>2 then response.write rsAdmin("AD_Menu") end if rsAdmin2.movenext wend end if '' # if not rsAdmin.eof then sPar=rsAdmin("AD_parent") rsAdmin.movenext wend that is my code

  • Matlab Simulation: Point (symbol) Moving from start point to end point and back

    - by niko
    Hi, I would like to create an animation to demonstrate LDPC coding which is based on Sum-Product Algorithm So far I have created a graph which shows the connections between symbol nodes (left) and parity nodes (right) and would like to animate points travelling from symbol to parity nodes and back. The figure is drawn by executing the following method: function drawVertices(H) hold on; nodesCount = size(H); parityNodesCount = nodesCount(1); symbolNodesCount = nodesCount(2); symbolPoints = zeros(symbolNodesCount, 2); symbolPoints(:, 1) = 0; for i = 0 : symbolNodesCount - 1 ji = symbolNodesCount - i; scatter(0, ji) symbolPoints(i + 1, 2) = ji; end; parityPoints = zeros(parityNodesCount, 2); parityPoints(:, 1) = 10; for i = 0 : parityNodesCount - 1 ji = parityNodesCount - i; y0 = symbolNodesCount/2 - parityNodesCount/2; scatter(10, y0 + ji) parityPoints(i + 1, 2) = y0 + ji; end; axis([-1 11 -1 symbolNodesCount + 2]); axis off %connect vertices d = size(H); for i = 1 : d(1) for j = 1 : d(2) if(H(i, j) == 1) plot([parityPoints(i, 1) symbolPoints(j, 1)], [parityPoints(i, 2) symbolPoints(j, 2)]); end; end; end; So what I would like to do here is to add another method which takes start point (x and y) and end point as arguments and animates a travelling circle (dot) from start to end and back along the displayed lines. I would appreciate if anyone of you could show the solution or suggest any useful tutorial about matlab simulations. Thank you!

    Hi folks, I've made a simple custom control: base.Style[HtmlTextWriterStyle.Position] = "absolute"; if (this.Expanded) // If the Calendar is expanded. this.Style[HtmlTextWriterStyle.Display] = "block"; else this.Style[HtmlTextWriterStyle.Display] = "none"; //create the containing table Panel pnl = new Panel(); pnl.ID = "pnl_" + this.ClientID; pnl.Enabled = true; SherlockIIITextBox txtCalendar = new SherlockIIITextBox(); txtCalendar.ID = "Cal_" + this.ClientID; pnl.Controls.Add(txtCalendar); ImageButton imgButton = new ImageButton(); imgButton.ImageUrl = ""; imgButton.ID = "img_" + this.ClientID; imgButton.BorderStyle = BorderStyle.NotSet; imgButton.OnClientClick = "o = document.getElementById('" + this.ClientID + "');if (o.style.display=='none'){o.style.display='block';}else{o.style.display='none';}"; pnl.Controls.Add(imgButton); pnl.RenderControl(writer); When I click the ImageButton it should render the calendar. But when I click the ImageButton nothing happens. Anyone got an idea?

  • ASP.NET MVC Paging for a search form

    - by James Alexander
    I've read several different posts on paging w/ in MVC but none describe a scenario where I have something like a search form and then want to display the results of the search criteria (with paging) beneath the form once the user clicks submit. My problem is that, the paging solution I'm using will create <a href="..."> links that will pass the desired page like so: http://mysite.com/search/2/ and while that's all fine and dandy, I don't have the results of the query being sent to the db in memory or anything so I need to query the DB again. If the results are handled by the POST controller action for /Search and the first page of the data is rendered as such, how do I get the same results (based on the form criteria specified by the user) when the user clicks to move to page 2? Some javascript voodoo? Leverage Session State? Make my GET controller action have the same variables expected by the search criteria (but optional), when the GET action is called, instantiate a FormCollection instance, populate it and pass it to the POST action method (there-by satisfying DRY)? Can someone point me in the right direction for this scenario or provide examples that have been implemented in the past? Thanks!

  • Why is creating a ring buffer shared by different processes so hard (in C++), what I am doing wrong?

    - by recipriversexclusion
    I am being especially dense about this but it seems I'm missing an important, basic point or something, since what I want to do should be common: I need to create a fixed-size ring buffer object from a manager process (Process M). This object has write() and read() methods to write/read from the buffer. The read/write methods will be called by independent processes (Process R and W) I have implemented the buffer, SharedBuffer<T&>, it allocates buffer slots in SHM using boost::interprocess and works perfectly within a single process. I have read the answers to this question and that one on SO, as well as asked my own, but I'm still in the dark about how to have different processes access methods from a common object. The Boost doc has an example of creating a vector in SHM, which is very similar to what I want, but I want to instantiate my own class. My current options are: Use placement new, as suggested by Charles B. to my question; however, he cautions that it's not a good idea to put non-POD objects in SHM. But my class needs the read/write methods, how can I handle those? Add an allocator to my class definition, e.g. have SharedBuffer<T&, Alloc> and proceed similarly to the vector example given in boost. This sounds really complicated. Change SharedBuffer to a POD class, i.e. get rid of all the methods. But then how to synchronize reading and writing between processes? What am I missing? Fixed-length ring buffers are very common, so either this problem has a solution or else I'm doing something wrong.

  • sqlite3 delete does not delete everything?

    Whats going on here? I would expect the following delete to delete everything from the table. Is there a fundamental mis-understanding of how sqlite3 behaves on my part? sqlite .schema CREATE TABLE ip_domain_table (ip_domain TEXT, answer TEXT, ttl INTEGER, PRIMARY KEY(ip_domain, answer, ttl)); sqlite select count(*) from ip_domain_table where ttl < 9999999999 ; 1605343 sqlite pragma cache_size=100000; delete from ip_domain_table where ttl < 9999999999; sqlite select count(*) from ip_domain_table where ttl < 9999999999 ; 258 Q: Why does the count show "258"?

  • Cutting Ubuntu to the bone for Virtualbox VM

    - by Monty
    I've been looking around for a Linux variant which will install only the software I need rather than everything Ubuntu (for example) puts in by default. This is to create a virtual machine in Virtualbox which has bash, apache, python, perl, SQLite, openssh and a few other programs but nothing else. I'd prefer to go with Ubuntu if possible but another modern distro would do as well (I like using apt-get and yum rather than downloading/compiling etc). So far, I've tried: SuseStudio.com, which is probably the best so far. Pressing F4 to get the boot options on Ubuntu 9.10, but there is no minimal installation (I think there was once). Arch Linux, slightly confusing install procedure but I might go back and try again. Gentoo, started well but fairly soon the HD on the virtual machine went to 2Gb, even before the installation had started in earnest (I'd partitioned the disks is all). I realise there are various "small" Linuxes around like Puppy, Feather, DSL, etc, but they seem to be aimed at desktop users or as a techie's toolkit, and I want a small-as-possible server distro which can be managed with tools like apt or yum or similar. TIA for any advice you can offer! -- Monty

  • Is this the right way to organize my database tables?

    - by Moss
    So I'm making a website that allows users to build contact lists. So their are users, the users have lists, and the lists have contacts. It seems to me that I need 3 tables for this but I just want to make sure. There would be a User table of course, and then a "List of Lists" table that has the username, and listname, as primary key along with whatever other info we want to attach to the lists as a whole. Finally, for lack of a better word, the List table which would again have the username/listname p.k., then the contact ID and notes and such that the user attaches to that contact on that specific list. I hope that is a clear explanation. For some reason I feel unsure about this arrangement. For one thing if the website becomes popular the List table could swell to billions of rows. And it also feels a little weird that everybody's list info is all jumbled up in the same table. I suppose I could create separate tables for each user and even for each list but that seems like a bad idea for other reasons. My db explanation assumes I can use foreign keys on my tables which at the moment isn't actually an option. If I can't get InnoDB tables enabled I will probably use ID's for the lists instead of depending on a compound key. Maybe I should do this anyway?

  • SQL Selects on subsets

    - by Adam
    I need to check if a row exists in a database; however, I am trying to find the way to do this that offers the best performance. This is best summarised with an example. Let's assume I have the following table: dbo.Person( FirstName varchar(50), LastName varchar(50), Company varchar(50) ) Assume this table has millions of rows, however ONLY the column Company has an index. I want to find out if a particular combination of FirstName, LastName and Company exists. I know I can do this: IF EXISTS(select 1 from dbo.Person where FirstName = @FirstName and LastName = @LastName and Company = @Company) Begin .... End However, unless I'm mistaken, that will do a full table scan. What I'd really like it to do is a query where it utilises the index. With the table above, I know that the following query will have great performance, since it uses the index: Select * from dbo.Person where Company = @Company Is there anyway to make the search only on that subset of data? e.g. something like this: select * from ( Select * from dbo.Person where Company = @Company ) where FirstName = @FirstName and LastName = @LastName That way, it would only be doing a table scan on a much narrower collection of data. I know the query above won't work, but is there a query that would? Oh, and I am unable to create temporary tables, as the user will only have read access.

  • use startActivityForResult from non-activity

    - by rayman
    Hi, I have MainActivity which is an Activity and other class(which is a simple java class), we`ll call it "SimpleClass". now i want to run from that class the command startActivityForResult. now i though that i could pass that class(SimpleClass), only MainActivity's context, problem is that, u cant run context.startActivityForResult(...); so the only way making SimpleClass to use 'startActivityForResult; is to pass the reference of MainActivity as an Activity variable to the SimpleClass something like that: inside the MainActivity class i create the instance of SimpleClass this way: SimpleClass simpleClass=new SimpleClass(MainActivity.this); now this is how SimpleClass looks like: public Class SimpleClass { Activity myMainActivity; public SimpleClass(Activity mainActivity) { super(); this.myMainActivity=mainActivity; } .... } public void someMethod(...) { myMainActivity.startActivityForResult(...); } now its working, but isnt a proper way of doing this? I`am afraid i could have some memory leaks in the future. thanks. ray.

  • Can't Compile Correct Mapping File

    - by NoOne
    Hello, Im now developping one application in C# with Remoting objects and NHibernate. So here is a image explaining how my projects are divided. Views Layer This layer will be responsible for the users interface. This layer will always use the Controls Layer to create and edit objects; Control Layer This is my persistence layer, here Ill have all the NHibernate configuration. This is my critic point, because ListSingleton Project will have only my RemoteObject. (Here I have the App.config file) Models Layer Entity layer. Here I only have the entities classes and their respective mapping. I’ve done a test solution with no remoting and only with the projects of the Control and Model Layers. It was all working ok. Now that I added the Views Layer and set the solution to start with projects Client and Server (Client calls the Control Layer and this would do a try to persist a object) I’m getting a error at : Configuration cfg = new Configuration(); cfg.AddXmlFile("mapping/User.hbm.xml"); InnerException: {"Could not compile the mapping document: mapping/User.hbm.xml"} InnerException.InnerException: {"Could not find the dialect in the configuration"} StackTrace in the InnerException.InnerException " em NHibernate.Dialect.Dialect.GetDialect(IDictionary`2 props)\r\n em NHibernate.Cfg.Configuration.AddValidatedDocument(NamedXmlDocument doc)" But I know that there is no error in the mapping file because I used in my test application.

I have a Dicitionary and I want to create a query based on this dictionary. So I loop through my dictionary and append to a string builder "PersonId = (GUID FROM DICTIONARY). I think the problem is were I append to PersonId for some reason I can't seem to convert my string guid to a Guid so the dynamic library don't crash. I have tried this to convert my string guid to a guid, but no luck. query.Append("(PersonId = Guid(" + person.Key + ")"); query.Append("(PersonId = " + person.Key + ")"); I am using VS 2010 RTM and RIA Services as well as the Entity Framework 4. //This is the loop I use foreach (KeyValuePair<Guid, PersonDetails> person in personsDetails) { if ((person.Value as PersonDetails).IsExchangeChecked) { query.Append("(PersonId = Guid.Parse(" + person.Key + ")"); } } //Domain service call var query = this.ObjectContext.Persons.Where(DynamicExpression.ParseLambda<Person, bool>(persons)); Please help, and if you know of a better way of doing this I am open to suggestions.

  • Improving field get and set performance with ASM or Javassist

    - by ng
    I would like to avoid reflection in an open source project I am developing. Here I have classes like the following. public class PurchaseOrder { @Property private Customer customer; @Property private String name; } I scan for the @Property annotation to determine what I can set and get from the PurchaseOrder reflectively. There are many such classes all using java.lang.reflect.Field.get() and java.lang.reflect.Field.set(). Ideally I would like to generate for each property an invoker like the following. public interface PropertyAccessor<S, V> { public void set(S source, V value); public V get(S source); } Now when I scan the class I can create a static inner class of PurchaseOrder like so. static class customer_Field implements PropertyAccessor<PurchaseOrder, Customer> { public void set(PurchaseOrder order, Customer customer) { order.customer = customer; } public Customer get(PurchaseOrder order) { return order.customer; } } With these I totally avoid the cost of reflection. I can now set and get from my instances with native performance. Can anyone tell me how I would do this. A code example would be great. I have searched the net for a good example but can find nothing like this. The ASM and Javasist examples are pretty poor also. The key here is that I have an interface that I can pass around. So I can have various implementations, perhaps one with Java Reflection as a default, one with ASM, and one with Javassist? Any help would be greatly appreciated.

  • Subclassing UIButton but can't access my properties

    - by Ross Ellerington
    Hi, I've created a sub class of UIButton: // // DetailButton.h #import <Foundation/Foundation.h> #import <MapKit/MapKit.h> @interface MyDetailButton : UIButton { NSObject *annotation; } @property (nonatomic, retain) NSObject *annotation; @end // // DetailButton.m // #import "MyDetailButton.h" @implementation MyDetailButton @synthesize annotation; @end I figured that I can then create this object and set the annotation object by doing the following: MyDetailButton* rightButton = [MyDetailButton buttonWithType:UIButtonTypeDetailDisclosure]; rightButton.annotation = localAnnotation; localAnnotation is an NSObject but it is really an MKAnnotation. I can't see why this doesn't work but at runtime I get this error: 2010-05-27 10:37:29.214 DonorMapProto1[5241:207] *** -[UIButton annotation]: unrecognized selector sent to instance 0x445a190 2010-05-27 10:37:29.215 DonorMapProto1[5241:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIButton annotation]: unrecognized selector sent to instance 0x445a190' ' I can't see why it's even looking at UIButton because I've subclassed that so it should be looking at the MyDetailButton class to set that annotation property. Have I missed something really obvious. It feels like it :) Thanks in advance for any help you can provide Ross

  • How do you rotate a sprite around its center by caclulating a new x and y position?

    - by Sam152
    I'm using Dark GDK and C++ to create a simple 2d game. I'm rotating an object but it rotates from the top left corner of the sprite. I have the following variables available: PlayerX PlayerY PlayerWidth PlayerHeight RotateAngle (360 x 0) Is there an algorithm that will modify the pivot point of the sprite, preferable to the center? Here is a small code sample: void Player::Move( void ) { if ( checkLeft() ) { PlayerX -= PlayerSpeed; if ( PlayerX < 0 ) PlayerX = 0; } if ( checkRight() ) { PlayerX += PlayerSpeed ; if ( PlayerX > 800 - PlayerWidth ) PlayerX = 800 - PlayerWidth; } if ( checkUp()) { PlayerY -= PlayerSpeed; if ( PlayerY < 0 ) PlayerY = 0; } if ( checkDown()) { PlayerY += PlayerSpeed; if ( PlayerY > 600 - PlayerHeight) PlayerY = 600 - PlayerHeight; } RotateAngle += 5; if(RotateAngle > 360) RotateAngle -=360; dbRotateSprite(Handle,RotateAngle); dbSprite ( 1 , PlayerX , PlayerY , Handle ); } Edit I'm considering opening up some reputation for this question, I have yet to be provided with an answer that works for me. If someone can provide an actual code sample that does the job, I'd be very happy. The problem with Blindy's answer is that no matter how much I simply translate it back or forth, the spirte still rotates around the top left hand corner and moving it somewhere rotating around the top left corner, then moving it back to the same position accomplishes nothing. Here is what I believe to be going on: Just so there is no confusion I have created a an image of what is going on. The left shows what is actually happening and the right shows what I need to happen.
