• How are integers converted to strings under the hood?

  - by CrazyJugglerDrummer

  I suppose the real question is how to convert base2/binary to base10. The most common application of this would probably be in creating strings for output: turning a chunk of binary numerical data into an array of characters. How exactly is this done? my guess: Seeing as there probably isn't a string predefined for each numerical value, I'm guessing that the computer goes through each bit of the integer from right to left, each time incrementing the appropriate values in the char array/base10 notation places. If we take the number 160 in binary (10100000), it would know that a 1 in the 8th place means 128, so it places 1 into the third column, 2 in the second, and 8 in the third. The 1 in the 6th column means 32, and it would add those values to the second and first place, carrying over if needed. After this it's an easy conversion to actual char codes.

  i you please help me out with my problem i am trying to create a function that output the data on a dropdownlist an setting my parameters my code goes as follow : public static List<string> GetTracks(out List<string> trackIds, string conferenceId) { var res = new List<string>(); trackIds = new List<string>(); var sqlCon = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString); SqlCommand cmd = new SqlCommand("select Track_name,Track_ID from TrackCommittee where Conference_id= @conferenceId", sqlCon); DataSet ds = new DataSet(); cmd.Connection.Open(); cmd.Parameters.Add(new SqlParameter("@conferenceId", conferenceId)); using (SqlDataReader sdr = cmd.ExecuteReader()) { while (sdr.Read()) { res.Add(sdr.GetString(sdr.GetOrdinal("Track_name"))); trackIds.Add(sdr.GetInt32(sdr.GetOrdinal("Track_ID")).ToString()); } } cmd.Connection.Close(); cmd.Dispose(); return res; } thanking you in advance

• Import into Aperture 3 without moving files

  - by delwin

  I like managing my own files, and this is definitely possible with Aperture 3. But there seems to be two ways to import into Aperture: either by dragging and dropping, or importing one folder at a time, manually, through the Aperture import window. BUT whenever I drag and drop the photos, it imports them into the Aperture library, making duplicates of everything. And if I add them manually through Aperture, I have to add each folder at a time, which is extremely tedious. Is there any solution?

• NHibernate mapping one table on two classes with where selection

  - by Rene Schulte

  We would like to map a single table on two classes with NHibernate. The mapping has to be dynamically depending on the value of a column. Here's a simple example to make it a bit clearer: We have a table called Person with the columns id, Name and Sex. The data from this table should be mapped either on the class Male or on the class Female depending on the value of the column Sex. In Pseudocode: create instance of Male with data from table Person where Person.Sex = 'm'; create instance of Female with data from table Person where Person.Sex = 'f'; The benefit is we have strongly typed domain models and can later avoid switch statements. Is this possible with NHibernate or do we have to map the Person table into a flat Person class first? Then afterwards we would have to use a custom factory method that takes a flat Person instance and returns a Female or Male instance. Would be good if NHibernate (or another library) can handle this.

• Buddy List: Relational Database Table Design

  - by huntaub

  So, the modern concept of the buddy list: Let's say we have a table called Person. Now, that Person needs to have many buddies (of which each buddy is also in the person class). The most obvious way to construct a relationship would be through a join table. i.e. buddyID person1_id person2_id 0 1 2 1 3 6 But, when a user wants to see their buddy list, the program would have to check the column 'person1_id' and 'person2_id' to find all of their buddies. Is this the appropriate way to implement this kind of table, or would it be better to add the record twice.. i.e. buddyID person1_id person2_id 0 1 2 1 2 1 So that only one column has to be searched. Thanks in advance.

• jqGrid editForm problem

  - by PaulStanek

  Hi, I have simply jqgrid definitions like this: jQuery("#C2").jqGrid({ url: '/Customers.mvc/GetGridData/', datatype: 'json', autowidth: 'true', mtype: 'GET', colNames: ['Nazwa', 'Symbol', 'Status', 'Miasto', 'Ulica', 'Budynek', 'Mieszkanie', 'Koda pocztowy', 'Domena', ' '], colModel: [ { name: 'Name', index: 'Name', align: 'left', editable: 'true', edittype: 'text' }, { name: 'Symbol', index: 'Symbol', align: 'left', editable: 'true', edittype: 'text' }, { name: 'Status', index: 'Status', align: 'left', editable: 'true', edittype: 'text' }, { name: 'City', index: 'City', align: 'left', editable: 'true', edittype: 'text' }, { name: 'Street', index: 'Street', align: 'left', editable: 'true', edittype: 'text' }, { name: 'Building', index: 'Building', align: 'left', editable: 'true', edittype: 'text' }, { name: 'Flat', index: 'Flat', align: 'left', editable: 'true', edittype: 'text'}, { name: 'PostalCode', index: 'PostalCode', align: 'left', editable: 'true', edittype: 'text' }, { name: 'Domain', index: 'Domain', align: 'left', editable: 'true', edittype: 'text'}, { name: 'ExtId', index: 'ExtId', align: 'left', editable: 'true', edittype: 'text'}, ], pager: jQuery('#C2_p'), rowNum: 30, rowList: [20, 30, 50], sortname: 'Name', sortorder: 'Asc', viewrecords: 'true', width: '80%', height: '100%', editurl: '/Customers.mvc/SaveCustomer/', postData: { gridId: 'Customers' }, caption: 'Klienci2' }).navGrid('#C2_p', { edit: true, add: true, del: true, search: false, refresh: false }, {},//Options for the Edit Dialog {},//Options for the Add Dialog {}//Options for D ); }); And when i call edit/add form it's appears without text edit inputs.

• How can I call a module in a Perl one-liner?

  - by Zaid

  Say I have a data file that I want to process; I want to take the maximum value of each of the column and append it to the end of each line. INPUT: T1 T2 T3 35.82 34.67 31.68 32.20 34.52 33.59 37.41 38.64 37.56 OUTPUT: T1 T2 T3 35.82 34.67 31.68 35.82 32.20 34.52 33.59 34.52 37.41 38.64 37.56 38.64 I'm trying to implement this as a one-liner. So far, this is what I've come up with, although it complains that &main::max is undefined: perl -MList::Util -ani.bak -e "print qq(@F).q( ).max(@F).qq(\n)" file1.txt It seems that I haven't loaded the List::Util module. What's wrong? And is the header column an issue? perlrun doesn't have a decent example on how to do this (actually it does now, my documentation was a little out-of-date).

  I'm trying to update a git repository on github. I made a bunch of changes, added them, committed then attempted to do a git push.

• Problem implementing Blinn–Phong shading model

  - by Joe Hopfgartner

  I did this very simple, perfectly working, implementation of Phong Relflection Model (There is no ambience implemented yet, but that doesn't bother me for now). The functions should be self explaining. /** * Implements the classic Phong illumination Model using a reflected light * vector. */ public class PhongIllumination implements IlluminationModel { @RGBParam(r = 0, g = 0, b = 0) public Vec3 ambient; @RGBParam(r = 1, g = 1, b = 1) public Vec3 diffuse; @RGBParam(r = 1, g = 1, b = 1) public Vec3 specular; @FloatParam(value = 20, min = 1, max = 200.0f) public float shininess; /* * Calculate the intensity of light reflected to the viewer . * * @param P = The surface position expressed in world coordinates. * * @param V = Normalized viewing vector from surface to eye in world * coordinates. * * @param N = Normalized normal vector at surface point in world * coordinates. * * @param surfaceColor = surfaceColor Color of the surface at the current * position. * * @param lights = The active light sources in the scene. * * @return Reflected light intensity I. */ public Vec3 shade(Vec3 P, Vec3 V, Vec3 N, Vec3 surfaceColor, Light lights[]) { Vec3 surfaceColordiffused = Vec3.mul(surfaceColor, diffuse); Vec3 totalintensity = new Vec3(0, 0, 0); for (int i = 0; i < lights.length; i++) { Vec3 L = lights[i].calcDirection(P); N = N.normalize(); V = V.normalize(); Vec3 R = Vec3.reflect(L, N); // reflection vector float diffuseLight = Vec3.dot(N, L); float specularLight = Vec3.dot(V, R); if (diffuseLight > 0) { totalintensity = Vec3.add(Vec3.mul(Vec3.mul( surfaceColordiffused, lights[i].calcIntensity(P)), diffuseLight), totalintensity); if (specularLight > 0) { Vec3 Il = lights[i].calcIntensity(P); Vec3 Ilincident = Vec3.mul(Il, Math.max(0.0f, Vec3 .dot(N, L))); Vec3 intensity = Vec3.mul(Vec3.mul(specular, Ilincident), (float) Math.pow(specularLight, shininess)); totalintensity = Vec3.add(totalintensity, intensity); } } } return totalintensity; } } Now i need to adapt it to become a Blinn-Phong illumination model I used the formulas from hearn and baker, followed pseudocodes and tried to implement it multiple times according to wikipedia articles in several languages but it never worked. I just get no specular reflections or they are so weak and/or are at the wrong place and/or have the wrong color. From the numerous wrong implementations I post some little code that already seems to be wrong. So I calculate my Half Way vector and my new specular light like so: Vec3 H = Vec3.mul(Vec3.add(L.normalize(), V), Vec3.add(L.normalize(), V).length()); float specularLight = Vec3.dot(H, N); With theese little changes it should already work (maby not with correct intensity but basically it should be correct). But the result is wrong. Here are two images. Left how it should render correctly and right how it renders. If i lower the shininess factor you can see a little specular light at the top right: Altough I understand the concept of Phong illumination and also the simplified more performant adaptaion of blinn phong I am trying around for days and just cant get it to work. Any help is appriciated. Edit: I was made aware of an error by this answer, that i am mutiplying by |L+V| instead of dividing by it when calculating H. I changed to deviding doing so: Vec3 H = Vec3.mul(Vec3.add(L.normalize(), V), 1/Vec3.add(L.normalize(), V).length()); Unfortunately this doesnt change much. The results look like this: and if I rise the specular constant and lower the shininess You can see the effects more clearly in a smilar wrong way: However this division just the normalisation. I think I am missing one step. Because the formulas like this just dont make sense to me. If you look at this picture: http://en.wikipedia.org/wiki/File:Blinn-Phong_vectors.svg The projection of H to N is far less than V to R. And if you imagine changing the vector V in the picture the angle is the same when the viewing vector is "on the left side". and becomes more and more different when going to the right. I pesonally would multiply the whole projection by two to become something similiar (and the hole point is to avoid the calculation of R). Altough I didnt read anythinga bout that anywehre i am gonna try this out... Result: The intension of the specular light is far too much (white areas) and the position is still wrong. I think I am messing something else up because teh reflection are just at the wrong place. But what? Edit: Now I read on wikipedia in the notes that the angle of N/H is in fact approximalty half or V/R. To compensate that i should multiply my shineness exponent by 4 rather than my projection. If i do that I end up with this: Far to intense but still one thing. The projection is at the wrong place. Where could i mess up my vectors?

• FlexUnit - howto check label text

  - by Maik

  I am trying to automatically verify certain conventions, such as label/table column header text (Sentence Case, use of colons, etc). It would be nice if there was a way in FlexUnit, or other means, to Iterate over all views in the app Get all titles, labels, column headers Run some pattern checks and fail where needed. Does anyone have a suggestion on what the best way would be to achieve that? I suppose I could do this on a code level on the MXML files, but it would be nicer if it could be integrated into the overall unit test suits. Thanks for any suggestions

  I have select values as follows: <select id="SelectBox" multiple="multiple"> <% foreach (var item in Model.Name) { %> <option value="<%= item.Value %>"><%=item.Text%></option> <% } %> </select> I have a function in jquery that will have to read both the text and value. I need to have the values in array so that I can display them in a table with a column Id and another column text. My problem is that Im not able to retrieve each and every value separately. Im having the text in one line, test1test2test3. function read() { $("#SelectBox").each(function() { var value = $(this).val(); var text = $(this).text(); alert(value);alert(text); }); }

• Sqlite: CURRENT_TIMESTAMP is in GMT, not the timezone of the machine

  - by BrianH

  I have a sqlite (v3) table with this column definition: "timestamp" DATETIME DEFAULT CURRENT_TIMESTAMP The server that this database lives on is in the CST time zone. When I insert into my table without including the timestamp column, sqlite automatically populates that field with the current timestamp in GMT, not CST. Is there a way to modify my insert statement to force the stored timestamp to be in CST? On the other hand, it is probably better to store it in GMT (in case the database gets moved to a different timezone, for example), so is there a way I can modify my select SQL to convert the stored timestamp to CST when I extract it from the table? Thanks in advance!

• ALTER TABLE without locking the table?

  - by Daniel

  When doing an ALTER TABLE statement in MySQL, the whole table is read-locked for the duration of the statement. If it's a big table, that means insert or update statements could be locked for a looooong time. Is there a way to do a "hot alter", like adding a column in such a way that the table is still updatable throughout the process? Mostly I'm interested in a solution for MySQL but I'd be interested in other RDBMS if MySQL can't do it. To clarify, my purpose is simply to avoid downtime when a new feature that requires an extra table column is pushed to production. Any database schema will change over time, that's just a fact of life. I don't see why we should accept that these changes must inevitably result in downtime; that's just weak.

• qtableview (libqt) how do I correctly create a QModelIndex

  I'm trying to enter edit mode on a specific cell like this void MainWindow::on_addButton_released(void) { tm->addRow(); tableView->scrollToBottom(); int ec=tm->firstWritableColumn(); int r=tm->rowCount(QModelIndex()); QModelIndex id = tm->index(r, ec, QModelIndex()); tableView->setCurrentIndex(id); tableView->edit(id); qDebug() << "row:" << r << " col:" << ec << "index:" << id; } my model creates an index like this QModelIndex TableModel::index(int row,int column,QModelIndex parent) const { Q_UNUSED(parent); return createIndex(row,column,0); } the debug output looks like this row: 9 col: 1 index: QModelIndex(9,1,0x0,TableModel(0xbf3f50) ) I'm fairly sure that the index is somehow invalid as setCurrentIndex doesn't seem to be working

• Binding Linq To Entities query results to a datagridview

  - by Nickson

  I just started playing with Linq to entities in a windows forms application and am not understanding one behavior that looks so simple though. If i type code below, i get ReadOnly records in my dataGridView Dim x = From n in Table1 _ Select n.FirstName, n.LastName, N.Department DataGridView1.DataSource = x But if i type the following code, i get editable rows in my dataGridView Dim x = From n in Table1 _ Select n DataGridView1.DataSource = x So, basically if i specify the column names to select and databind to my DataGridView1, the rows are readonly but if i do not specify the column names and databind to the DataGridView, the rows are editable and i don't understand why.

• Prim's MST algorithm implementation with Java

  - by user1290164

  I'm trying to write a program that'll find the MST of a given undirected weighted graph with Kruskal's and Prim's algorithms. I've successfully implemented Kruskal's algorithm in the program, but I'm having trouble with Prim's. To be more precise, I can't figure out how to actually build the Prim function so that it'll iterate through all the vertices in the graph. I'm getting some IndexOutOfBoundsException errors during program execution. I'm not sure how much information is needed for others to get the idea of what I have done so far, but hopefully there won't be too much useless information. This is what I have so far: I have a Graph, Edge and a Vertex class. Vertex class mostly just an information storage that contains the name (number) of the vertex. Edge class can create a new Edge that has gets parameters (Vertex start, Vertex end, int edgeWeight). The class has methods to return the usual info like start vertex, end vertex and the weight. Graph class reads data from a text file and adds new Edges to an ArrayList. The text file also tells us how many vertecis the graph has, and that gets stored too. In the Graph class, I have a Prim() -method that's supposed to calculate the MST: public ArrayList<Edge> Prim(Graph G) { ArrayList<Edge> edges = G.graph; // Copies the ArrayList with all edges in it. ArrayList<Edge> MST = new ArrayList<Edge>(); Random rnd = new Random(); Vertex startingVertex = edges.get(rnd.nextInt(G.returnVertexCount())).returnStartingVertex(); // This is just to randomize the starting vertex. // This is supposed to be the main loop to find the MST, but this is probably horribly wrong.. while (MST.size() < returnVertexCount()) { Edge e = findClosestNeighbour(startingVertex); MST.add(e); visited.add(e.returnStartingVertex()); visited.add(e.returnEndingVertex()); edges.remove(e); } return MST; } The method findClosesNeighbour() looks like this: public Edge findClosestNeighbour(Vertex v) { ArrayList<Edge> neighbours = new ArrayList<Edge>(); ArrayList<Edge> edges = graph; for (int i = 0; i < edges.size() -1; ++i) { if (edges.get(i).endPoint() == s.returnVertexID() && !visited(edges.get(i).returnEndingVertex())) { neighbours.add(edges.get(i)); } } return neighbours.get(0); // This is the minimum weight edge in the list. } ArrayList<Vertex> visited and ArrayList<Edges> graph get constructed when creating a new graph. Visited() -method is simply a boolean check to see if ArrayList visited contains the Vertex we're thinking about moving to. I tested the findClosestNeighbour() independantly and it seemed to be working but if someone finds something wrong with it then that feedback is welcome also. Mainly though as I mentioned my problem is with actually building the main loop in the Prim() -method, and if there's any additional info needed I'm happy to provide it. Thank you. Edit: To clarify what my train of thought with the Prim() method is. What I want to do is first randomize the starting point in the graph. After that, I will find the closest neighbor to that starting point. Then we'll add the edge connecting those two points to the MST, and also add the vertices to the visited list for checking later, so that we won't form any loops in the graph. Here's the error that gets thrown: Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at java.util.ArrayList.rangeCheck(Unknown Source) at java.util.ArrayList.get(Unknown Source) at Graph.findClosestNeighbour(graph.java:203) at Graph.Prim(graph.java:179) at MST.main(MST.java:49) Line 203: return neighbour.get(0); in findClosestNeighbour() Line 179: Edge e = findClosestNeighbour(startingVertex); in Prim()

• configuring slime in emacs

  - by CodeKingPlusPlus

  I am in the process of configuring slime for emacs. So far I have read about basic functionality for common lisp such as C-c C-q which invokes the command slime-close-parens-at-point which places the proper number of parens where your mouse is. Another command that seemed cool was invoked by C-c C-c and it would pass the code you are editing in a buffer to the REPL, and "compile" it. Why won't these commands work for me? Anyway, I have downloaded slime via M-x list-packages and do not seem to have this functionality (C-h w and then any of these commands tells me that these commands do note exist). So, I saw a bunch of other slime extensions such as slime-repl', 'slime-fuzzy' and 'hippie-expand-slime'. So I again usedM-x list-packages` and downloaded them. Still I did not have these commands. Here is the content of my emacs file relevant to slime: ;;;Common Lisp and Slime (add-to-list 'load-path "/home/s2s2/.emacs.d/elpa/slime-20130626.1151") (add-to-list 'load-path "/home/s2s2/.emacs.d/elpa/slime-repl-201000404") (add-to-list 'load-path "/home/s2s2/.emacs.d/elpa/hippie-expand-slime-20130226.1656") (add-to-list 'load-path "/home/s2s2/.emacs.d/elpa/slime-fuzzy-20100404") (require 'slime) (setq slime-lisp-implementations `((sbcl ("/usr/bin/sbcl")) (ecl ("/usr/bin/ecl")) (clisp ("/usr/bin/clisp" "-q -I")))) (require 'slime-repl) (require 'slime-fuzzy) (require 'hippie-expand-slime) When I execute M-x slime I get the following message in the inferior-lisp buffer where I can execute common lisp code (however, shouldn't this be the slime-repl since I required it?): STYLE-WARNING: redefining EMACS-INSPECT (#<BUILT-IN-CLASS T>) in DEFMETHOD STYLE-WARNING: Implicitly creating new generic function STREAM-READ-CHAR-WILL-HANG-P.

• Adding childs to list of parents with jquery /mvc2

  - by John Landheer

  Hi, I have a table of products on my page, each product has zero or more colors, the colors are shown as a list beneath the product. After the colors I have a button to add a color. The button will do an ajax call with the parent product id to a controller which will return a JSON object with color information. My problem is where to store the product id in the DOM, should I put it in a hidden field and use jquery in the click event of the "add color" to get to it? What is the best way to do this? TIA, John EDIT: The page is initially rendered on the server so I don't want to use jquery to add the id's to the page.

• nhibernate : One to One mapping

  - by frosty

  I have the following map. I wish to map BasketItem to the class "Product". So basically when i iterate thru the basket i can get the product name <class name="BasketItem" table="User_Current_Basket"> <id name="Id" type="Int32" column="Id" unsaved-value="0"> <generator class="identity"/> </id> <property name="ProductId" column="Item_ID" type="Int32"/> <one-to-one name="Product" class="Product"></one-to-one> </class> How do specifiy that product should match BasketItem.ProductId with Product.Id Also i've read that i should avoid one-to-one and just use one-to-many? If i was to do that how do i ensure i just get one product and not a collection.
