• read text files containing binary data as a single matrix in matlab

  - by user1716595

  I have a text file which contains binary data in the following manner: 00000000000000000000000000000000001011111111111111111111111111111111111111111111111111111111110000000000000000000000000000000 00000000000000000000000000000000000000011111111111111111111111111111111111111111111111000111100000000000000000000000000000000 00000000000000000000000000000000000011111111111111111111111111111111111111111111111111111111100000000000000000000000000000000 00000000000000000000000000000000000111111111111111111111111111111111111111111111111111111111100000000000000000000000000000000 00000000000000000000000000000000000011111111111111111111111111111111111111111111111111111111100000000000000000000000000000000 00000000000000000000000000000000000000011111111111111111111111111111111111111111111111111111100000000000000000000000000000000 00000000000000000000000000000000000000011111111111111111111111111111111111111111111111000111110000000000000000000000000000000 00000000000000000000000000000000000000111111111111111111111111111111111111111111111111111111110000000000000000000000000000000 00000000000000000000000000000000000000000000111111111111111111111111111111111111110000000011100000000000000000000000000000000 00000000000000000000000000000000000000011111111111111111111111111111111111111111111111100111110000000000000000000000000000000 00000000000000000000000000000000000111111111111111111111111111111111111111111111111111110111110000000000000000000000000000000 00000000000000000000000000000000001111111111111111111111111111111111111111111111111111111111100000000000000000000000000000000 00000000000000000000000000000000000000001111111111111111111111111111111111111111111111000011100000000000000000000000000000000 00000000000000000000000000000000000000001111111111111111111111111111111111111111111111000011100000000000000000000000000000000 00000000000000000000000000000000000001111111111111111111111111111111111111111111111111111111000000000000000000000000000000000 00000000000000000000000000000000000000011111111111111111111111111111111111111111111110000011100000000000000000000000000000000 00000000000000000000000000000000000000000000011111111111111111111111111111111111100000000011100000000000000000000000000000000 00000000000000000000000000000000000000111111111111111111111111111111111111111111111111110111100000000000000000000000000000000 Plz note that each 1 or 0 is independent i.e the values are not decimal.I need to find the column wise sum of the file.There are 125 columns in all (here it is jumping onto the next line) and there are 840946 rows. I have tried textread,fscanf and a few other matlab commands but the result is that they all read each row in decimal format and create a 840946*1 array.I want to create a 840946*125 array to compute a column wise sum. Kindly help, Thanks!

• SQL: joining multiples tables into one.

  - by Graveen

  I have 4 tables. r1, r2, r3 and r4. The table columns are the following: rId | rName I want to have, in fine, an unique table - let's call it R. Obviously, R will have the following structure: rTableName | rId | rName I'm looking for a solution, and the more natural for me is to: add a single column to all rX insert this column the table name i'm processing generate SQLs and concatenate them all Although I see exactly how to perform 1 and 3 with batching, editing, etc... (I have only to perform it once and for all), I don't see how to do the point 2: self-getting the tablename to insert into SQL. Have you an idea / or a different way to do that could solve my problem? Note: In fact, there are 250+ rX tables. That's why i can't do this manually. Note2: Precisely, this is with MySQL.

• QWinWidget's position is always 0 (zero)

  - by Kevin

  I hosted a QWinWidget in a CView and want it to stay at a designated position when resizing. But QWinWidget always moves to (0, 0), i.e. left-top corner of the CView. I tried to debug in this way: QWinWidget* pWidget = new QWinWidget(pCView); pWidget->move(50, 50); QPoint pos = pWidget->pos(); Note that: the pos is always (0, 0). Why is that?

• Setting new class variables inside a module

  - by Sean McCleary

  I have a plugin I have been working on that adds publishing to ActiveRecord classes. I extend my classes with my publisher like so: class Note < ActiveRecord::Base # ... publishable :related_attributes => [:taggings] end My publisher is structured like: module Publisher def self.included(base) base.send(:extend, ClassMethods) @@publishing_options = [] # does not seem to be available end module ClassMethods def publishable options={} include InstanceMethods @@publishing_options = options # does not work as class_variable_set is a private method # self.class_variable_set(:@@publishing_options, options) # results in: uninitialized class variable @@publishing_options in Publisher::ClassMethods puts "@@publishing_options: #{@@publishing_options.inspect}" # ... end # ... end module InstanceMethods # results in: uninitialized class variable @@publishing_options in Publisher::InstanceMethods def related_attributes @@publishing_options[:related_attributes] end # ... end end Any ideas on how to pass options to publishable and have them available as a class variable?

• Regex to catch all files but those starting with "."

  - by tmslnz

  In a directory with mixed content such as: .afile .anotherfile bfile.file bnotherfile.file .afolder/ .anotherfolder/ bfolder/ bnotherfolder/ How would you catch everything but the files (not dirs) starting with .? I have tried with a negative lookahead ^(?!\.).+? but it doesn't seem to work right. Please note that I would like to avoid doing it by excluding the . by using [a-zA-Z< plus all other possible chars minus the dot >] Any suggestions?

• Django Forms: TimeField Validation

  - by Tom

  I feel like I'm missing something obvious here. I have a Django form with a TimeField on it. I want to be able to allow times like "10:30AM", but I cannot get it to accept that input format or to use the "%P" format (which has a note attached saying it's a "Proprietary extension", but doesn't say where it comes from). Here's the gist of my form code: calendar_widget = forms.widgets.DateInput(attrs={'class': 'date-pick'}, format='%m/%d/%Y') time_widget = forms.widgets.TimeInput(attrs={'class': 'time-pick'}) valid_time_formats = ['%P', '%H:%M%A', '%H:%M %A', '%H:%M%a', '%H:%M %a'] class EventForm(forms.ModelForm): start_date = forms.DateField(widget=calendar_widget) start_time = forms.TimeField(required=False, widget=time_widget, help_text='ex: 10:30AM', input_formats=valid_time_formats) end_date = forms.DateField(required=False, widget=calendar_widget) end_time = forms.TimeField(required=False, widget=time_widget, help_text='ex: 10:30AM', input_formats=valid_time_formats) description = forms.CharField(widget=forms.Textarea) Any time I submit "10:30AM", I get a validation error. The underlying model has two fields, event_start and event_end, no time fields, so I don't think the problem is in there. What stupid thing am I missing?

• Random select is not always returning a single row.

  - by Lieven

  The intention of following (simplified) code fragment is to return one random row. Unfortunatly, when we run this fragment in the query analyzer, it returns between zero and three results. As our input table consists of exactly 5 rows with unique ID's and as we perform a select on this table where ID equals a random number, we are stumped that there would ever be more than one row returned. Note: among other things, we already tried casting the checksum result to an integer with no avail. DECLARE @Table TABLE ( ID INTEGER IDENTITY (1, 1) , FK1 INTEGER ) INSERT INTO @Table SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 SELECT * FROM @Table WHERE ID = ABS(CHECKSUM(NEWID())) % 5 + 1

• Drupal - Views + node preview woes

  - by Ace

  Hey there! I have a few Views on my Drupal 6 site which take care of some of a node's fields. For example, I have a content type called Country, which has a field called Capital. I've excluded this field in the node display, but there is a view that takes the node ID as an argument and displays it in the right column. This is all very pretty and has been working out well for me, but how do I take care of the node preview mode? Since the node isn't saved yet, the Capital field won't have its new value yet. Note: I am ready to do some very dirty hacks to make this work :)

• Is there a definitive list of differences between the Ruby on Rails versions?

  - by jedijim

  Is there a list of the differences between the various versions of Rails somewhere on the web? I'm working through an older book about Rails that uses Rails 1.2. I know there are other ways to learn Rails these days, but I thought it would be interesting to try and convert all of the exercises in the book to a more modern versions of Rails (I'm currently working with 2.3.5). A comprehensive list of differences between the various releases would be very helpful. Note that I don't consider the git log a good source of information, as commit messages almost never tell the full story.

• Casting Class into String and Vice Versa in JAVA

  - by topgun_ivard

  I have a program in which I need to store a Class object into memory by casting it into String. Is it possible to convert the String back into the original Class so that I can use that class variables? I am doing this in JAVA. Example: test.java class hello{ public String h1; public String h2; } public class test { public static void main(String[] args) { hello h = new hello(); h.h1 = "hello"; h.h2 = "world"; String s = h.toString(); System.out.println("Print s : "+s); // Now I need to convert String s into type hello so that // I can do this: // (hello)s.h1; // (hello)s.h2; } } NOTE: this is not a homework, this is a personal project and I would be grateful if anyone can help! Thanks! Ivar

• How to Validate an XML Node against an XSD in C++?

  - by Ashish

  Hi Please note that I'm asking for validation against a particular node and not the whole file. For examples <somexmldoc> <someNode> <UserDefinedNode> </> <UserDefinedNode> </> </someNode> </somexmldoc> For this XML doc, I have an wholeDoc.XSD which could be used to validate the whole document except "UserDefinedNode" (This node is specified with "any" tag in xsd, which allows a user to define anything under that node). Is it possible to have a separate userdefined.XSD file to validate "UserDefinedNode"? Is it possible to use MSXML for C++ (IXMLDomDocument) to validate this? Thanks!

• Regex whitespace and special characters

  - by Sam R.

  I have this regular expression: [^\\s\"']+|\"([^\"]*)\"|'([^']*)' which works for splitting a string by white spaces, and anything within a quotation is not delimited. However, I notice that if I put in a string that starts with "" no matches are found. How would I correct this? For example, if I enter " test 2". I want it to match to [, test, 2] Note: using java to compile the regex, here is some code Pattern pattern = Pattern.compile("[^\\s\"']+|\"([^\"]*)\"|'([^']*)'"); Matcher matcher = pattern.matcher(SomeString); while (matcher.find()){ String temp = matcher.group(); //... Do something ... } Thanks.

• Optimality of Binary Search

  - by templatetypedef

  Hello all- This may be a silly question, but does anyone know of a proof that binary search is asymptotically optimal? That is, if we are given a sorted list of elements where the only permitted operation on those objects is a comparison, how do you prove that the search can't be done in o(lg n)? (That's little-o of lg n, by the way.) Note that I'm restricting this to elements where the only operation permitted operation is a comparison, since there are well-known algorithms that can beat O(lg n) on expectation if you're allowed to do more complex operations on the data (see, for example, interpolation search). Thanks so much! This has really been bugging me since it seems like it should be simple but has managed to resist all my best efforts. :-)

• How do you render a rails partial that is outside of a namespace in a view that is inside of a namespace?

  - by iand675

  I've got a 'static' controller and static views that are pages that don't utilize ruby in their views. For these pages, I have a sitemap partial that is generated programatically and used in the application layout file. Namespaced routes still use the application layout file but are taking the static routes and trying to namespace them too. Here's the relevant portion of the route file: namespace :admin do resources :verse_categories resources :verses resources :songs resources :flowers resources :visits, :except => [:new, :create] end match ':action' => 'static' root :to => 'static#home' Here's the error I'm getting: No route matches {:controller=>"admin/static", :action=>"about"} Note that about is one of the static pages that the sitemap partial uses. So, how can I resolve this routing issue so that it's not trying to find my static sites inside of the admin namespace? Any help would be appreciated!

Here is the sample POJO class class Product{ int product_id; String name; String description; } and Class Item{ int item_id; String name; String description; int quantity; int product_id; //Note that there is no composed product object. } Now I want to perform a query like select * from Product p left outer join Item i on p.product_id = i.item_id I want a multidimensional array as an output of this query so that I can have separate instances of Product and Item, instead of one composed in another. Is there any way to do this in Hibernate?

• Best .NET Solution for Frequently Changed Database

  - by sestocker

  I am currently architecting a small CRUD applicaton. Their database is a huge mess and will be changing frequently over the course of the next 6 months to a year. What would you recommend for my data layer: 1) ORM (if so, which one?) 2) Linq2Sql 3) Stored Procedures 4) Parametrized Queries I really need a solution that will be dynamic enough (both fast and easy) where I can replace tables and add/delete columns frequently. Note: I do not have much experience with ORM (only a little SubSonic) and generally tend to use stored procedures so maybe that would be the way to go. I would love to learn Ling2Sql or NHibernate if either would allow for the situation I've described above.

• Detecting coincident subset of two coincident line segments

  - by Jared Updike

  This question is related to: How do I determine the intersection point of two lines in GDI+? (great explanation of algebra but no code) How do you detect where two line segments intersect? (accepted answer doesn't actually work) But note that an interesting sub-problem is completely glossed over in most solutions which just return null for the coincident case even though there are three sub-cases: coincident but do not overlap touching just points and coincident overlap/coincident line sub-segment For example we could design a C# function like this: public static PointF[] Intersection(PointF a1, PointF a2, PointF b1, PointF b2) where (a1,a2) is one line segment and (b1,b2) is another. This function would need to cover all the weird cases that most implementations or explanations gloss over. In order to account for the weirdness of coincident lines, the function could return an array of PointF's: zero result points (or null) if the lines are parallel or do not intersect (infinite lines intersect but line segments are disjoint, or lines are parallel) one result point (containing the intersection location) if they do intersect or if they are coincident at one point two result points (for the overlapping part of the line segments) if the two lines are coincident

• Error 2908 when installing assemblies into GAC

  - by yfrolov

  Hi, I'm receiving 2908 (0x80131047: The given assembly name or code-base is invalid) error when running my MSI package. The problem occures when the MSI tries to deploy a component with .NET assembly into a GAC. NOTE: only assemblies with dependencies fail. The MSI is created with IS 2010. I am able to deploy the assembly manually with GACUTIL. I verified .NET Framework (all versions upto 3,5)is installed. I verified assembly properties are identical with MsiAssemblyName table properties. However, somehow I had made the installation working fine before. But when the product was moved to Visual Studio 2008 and .NET 3.0 I started facing the problem. Do you guys have any thought on this. Any ideas are appreciated. Thanks much!

• HTML reuse, create template

  - by nanonerd

  After about a year doing Asp.net web forms, I stepped out (for the most part) from the .net world. I'm now working on a webapp that uses a lot of client side scripting and uses WebAPI for data access. I have a HTML section that allows note taking. I would like to make this HTML section into a template that I can reuse elsewhere on the site (e.g., insert this piece of HTML code into another web page). I'm a bit befuddled on how to go about this. Think of my problem as trying to create a "user control" in asp.net web forms ... only that I am not using web forms. Just good old fashioned HTML, CSS, Javascript, jquery, and knockout. Conceptually, I'd think that others have been in the same spot as myself. Can anyone elaborate a solution or at least provide some pointers? Thanks !

• Exploding a range of dates with LINQ

  - by Robert Gowland

  If I have a pair of dates, and I want to generate a list of all the dates between them (inclusive), I can do something like: System.DateTime s = new System.DateTime(2010, 06, 05); System.DateTime e = new System.DateTime(2010, 06, 09); var list = Enumerable.Range(0, (e - s).Days) .Select(value => s.AddDays(value)); What I'm stuck on is that I've got a list of pairs of dates that I want to explode into a list of all the dates between them. Example: {2010-05-06, 2010-05-09}, {2010-05-12, 2010-05-15} should result in {2010-05-06, 2010-05-07, 2010-05-08, 2010-05-09, 2010-05-12, 2010-05-13, 2010-05-14, 2010-05-15} Note the pairs of dates are guaranteed not to overlap each other.
