• image filter that spits out pi

  - by patrickinmpls

  I've seen this before but I forgot what's its called. Does anyone know of software that takes a picture and spits out an image of the number pi, ie. 3.14... not the symbol? It basically kinda looks like ascii art but the numbers are different shades of gray so it is like a black and white photo. Thanks!

• minimum enclosing rectangle of fixed aspect ratio

  - by Ramya Narasimha

  I have an Image with many rectangles at different positions in the image and of different sizes (both overlapping and non-overlapping). I also have a non-negative scores associated with each of these rectangles. My problem now is to find one larger rectangle *of a fixed (given) aspect ratio* that encloses as many of these rectangles as possible. I am looking for an algorithm to do this, if anyone has a solution, even a partial one it would be helpful. Please note that the positions of the rectangles in the image is fixed and cannot be moved around and there is no orientation issue as all of them are upright.

• Oracle - Is there any effects of not having a primary key on a table ?

  - by Sathya

  We use sequence numbers for primary keys on the tables. There are some tables where we dont really use the primary key for any querying purpose. But, we have Indexes on other columns. These are non-unique indexes. The queries use these non-primary key columns in the WHERE conditions. So, I dont really see any benefit of having a primary key on such tables. My experience with SQL 2000 was that, it used to replicate tables which had some primary key. Otherwise it would not. I am using Oracle 10gR2. I would like to know if there are any such side-effects of having tables that dont have primary key.

• Linux standard input issue

  - by George2

  Hello everyone, I am new to Linux. And I am using Red Hat Enterprise Version 5. There is a ruby program which use standard input as its input (e.g. the Ruby program process input from standard input). I think standard input should be keyboard, correct? So, I think other kinds of input (non-standard input) should not work (i.e. the ruby program should not be able to read input from such non-standard input), but actually I have tried using pipe works, I am so confused because I think pipe should be some other kinds of input -- other than standard input, why it could work? i.e. put text "123" in abc.txt with pipe, could achieve the same result as using keyboard as input to type "123" for the ruby program. Here is the sample which works and makes me confused, cat abc.txt | ~/test/rubysrc/foo.rb thanks in advance, George

• Word Opening Text Files by default as RTL, should be LTR

  - by wonea

  I've noticed recently that Microsoft Word 2007 on Windows XP is opening by default straight text files as RTL instead of LTR. These are English written files, and contain no Unicode or characters other than ASCII. I work in three or four languages on the computer so have the language bar open, this problem happens when the language is selected to EN (United Kingdom). Is there a setting I'm missing somewhere, perhaps in Word itself?

• Does margin-left:2px; render faster than margin:0 0 0 2px;?

  - by Christopher Altman

  Douglas Crockford describes the consequence of Javascript inquiring a node's style. How simply asking for the margin of a div causes the browser to 'reflow' the div in the browser's rendering engine four times. So that made me wonder, during the initial rendering of a page (or in Crockford's jargon a "web scroll") is it faster to write CSS that defines only the non-zero/non-default values? To provide an example: div{ margin-left:2px; } Than div{ margin:0 0 0 2px; } I know consequence of this 'savings' is insignificant, but I think it is still important to understand how the technologies are implemented. Also, this is not a question about formatting CSS--this is a question about the implementations of browsers rendering CSS. Reference: http://developer.yahoo.com/yui/theater/video.php?v=crockonjs-4

• What does it mean when git pull causes a conflict but git pull --rebase doesn't?

  - by Jason Baker

  I'm pulling from a repository that only I have access to. As far as I know, I've only pushed to it from one repository. A couple of times, I've pulled from it and gotten this: To [email protected]:tsched_dev.git ! [rejected] master -> master (non-fast-forward) error: failed to push some refs to '[email protected]:tsched_dev.git' To prevent you from losing history, non-fast-forward updates were rejected Merge the remote changes before pushing again. See the 'Note about fast-forwards' section of 'git push --help' for details. Generally, that just means that I have to do a git pull (although all the changes should be fast-forwardable). When I do a git pull, I get conflicts. If I do a git pull --rebase, it works fine. What am I doing wrong?

• how best to set text alignment in a table

  - by ericslaw

  Does anyone know of a jquery plugin or snippet that will auto-text-align cells in a table based on content? Specifically, all table cells would be right justified unless there is a visible non-number related character in the cell, then it would be left justified. I'd like to use something like this regular expression to identify non-number related characters in a cell: /[^0-9% +-()]/ Is there a real simple way to accomplish this? I would think something like this: $("td:contains('[^0-9% +-()]')").addClass("left"); would do the trick, but I don't think 'contains' can take a regular expression.

• Should I use Perl or PHP or something else for this project?

  - by Clinton

  I'm about to embark on a project that will need to: Process XML Heavy text parsing of non-xml documents Insertion of data from xml and non-xml documents into a relational DB. Present processed data to user from db using webpages. The website will be subject to short periods of very heavy loads to pages (300+ visitors a minute for several minutes), but most of the time will be idle (a dozen or so visitors a minute). The ability to cache or scale to load will be very nice. I have a very strong background in Java and web services, but I do not want to use Java for this project as I'd like to diversify my skill set. Which language would you recommend and what are some pros and cons that you might recognize from your own experiences?

• UAC on Win2k8/VIsta x64 - local "Administrator" works but domain account in Administrators group fai

  - by deltanine

  I have come across a strange problem in one of our applications on win2k8/Vista x64 with UAC enabled. It is a process which hosts the UI for our service and runs in the context of the logged on user. When logged in as a domain user who is a member of the "Administrators" group, writing to the registry under HKLM fails due to UAC with access denied. But when logged in as the local "Administrator" account (non-domain) then writing to the registry succeeds. Both accounts are adminstrators - is there a distinction between domain and non-domain accounts with UAC? What gives?

• What Web design tool would make a good CityDesk replacement?

  - by Joshua Fox

  I am looking for a tool for building static template-based web sites, your typical brochure-ware for a non-profit or a personal site. I have used CityDesk, but that is out-of-date, unsupported, and has certain problems. Of course there are lots of tools out there, but I cannot find anything similar to CityDesk: WYSIWYG as well as HTML coding a templating system not overdesigned like, say, Dreamweaver built for developers who understand HTML/JS/CSS but easier to use than hand-coding of PHP, Ruby, or other templates in a text editor supporting the editing of pages by non-developers preferably free I'd also like it to be CSS-aware; and to have lots of free templates available. Or alternatively, static template-based sites are often developed nowadays on the Web using a CMS like Django; is that the way to go? Edit: Namo, DreamWeaver, NetObjects Fusion, Coffee Cup, Evrsoft First Page, and Microsoft Expression might be candidates. I'll appreciate comments on these based on the criteria above.

• Get positions for NAs only in the "middle" of a matrix column

  - by Abiel

  I want to obtain an index that refers to the positions of NA values in a matrix where the index is true if a given cell is NA and there is at least one non-NA value before and after it in the column. For example, given the following matrix [,1] [,2] [,3] [,4] [1,] NA 1 NA 1 [2,] 1 NA NA 2 [3,] NA 2 NA 3 the only value of the index that comes back TRUE should be [2,2]. Is there a compact expression for what I want to do? If I had to I could loop through columns and use something like min(which(!is.na(x[,i]))) to find the first non-NA value in each column, and then set all values before that to FALSE (and the same for all values after the max). This way I would not select leading and trailing NA values. But this seems a bit messy, so I'm wondering if there is a cleaner expression that does this without loops.

• RAII: Initializing data member in const method

  - by Thomas Matthews

  In RAII, resources are not initialized until they are accessed. However, many access methods are declared constant. I need to call a mutable (non-const) function to initialize a data member. Example: Loading from a data base struct MyClass { int get_value(void) const; private: void load_from_database(void); // Loads the data member from database. int m_value; }; int MyClass :: get_value(void) const { static bool value_initialized(false); if (!value_initialized) { // The compiler complains about this call because // the method is non-const and called from a const // method. load_from_database(); } return m_value; } My primitive solution is to declare the data member as mutable. I would rather not do this, because it suggests that other methods can change the member. How would I cast the load_from_database() statement to get rid of the compiler errors?

• Why aren't operator conversions implicitly called for templated functions? (C++)

  - by John Gordon

  I have the following code: template <class T> struct pointer { operator pointer<const T>() const; }; void f(pointer<const float>); template <typename U> void tf(pointer<const float>); void g() { pointer<float> ptr; f(ptr); tf(ptr); } When I compile the code with gcc 4.3.3 I get a message (aaa.cc:17: error: no matching function for call to ‘tf(pointer<float>&)’) indicating that the compiler called 'operator pointer<const T>' for the non-templated function f(), but didn't for the templated function tf(). Why and is there any workaround short of overloading tf() with a const and non-const version? Thanks in advance for any help.

• AIO network sockets and zero-copy under Linux

  - by remyhorton

  I have been experimenting with async Linux network sockets (aio_read et al in aio.h/librt), and one thing i have been trying to find out is whether these are zero-copy or not. Pretty much all i have read so far discusses file I/O, whereas its network I/O i am interested in. AIO is a bit of a pain to use and i suspect is non-portable, so wondering whether its worth persevering with it. Zero-copy is just about the only advantage (albiet a major one for my purposes) it would have over (non-blocking) select/epoll..

• Why is the dictionary debug visualizer less useful in Visual Studio 2010?

  - by Kevin

  I was debugging in Visual Studio 2010, which we just installed and trying to look at a dictionary in the quick watch window. I see Keys and Values, but drilling into those shows the Count and Non-Public members, Non-Public members continues the trail and I never see the values in the dictionary. I can run test.Take(10) and see the values, but why should I have to do that. I don't have VS 2008 installed anymore to compare, but it seems that I could debug a dictionary much easier. Why is it this way now? Is it just a setting I set somehow on my machine? Test code: Dictionary<string, string> test = new Dictionary<string, string>(); test.Add("a", "b");

• Is it a good idea to use a computed column as part of a primary key ?

  - by Brann

  I've got a table defined as : OrderID bigint NOT NULL, IDA varchar(50) NULL, IDB bigint NULL, [ ... 50 other non relevant columns ...] The natural primary key for this table would be (OrderID,IDA,IDB), but this it not possible because IDA and IDB can be null (they can both be null, but they are never both defined at the same time). Right now I've got a unique constraint on those 3 columns. Now, the thing is I need a primary key to enable transactional replication, and I'm faced with two choices : Create an identity column and use it as a primary key Create a non-null computed column C containing either IDA or IDB or '' if both columns were null, and use (OrderID,C) as my primary key. The second alternative seams cleaner as my PK would be meaningful, and is feasible (see msdn link), but since I've never seen this done anywhere, I was wondering if they were some cons to this approach.

• How to make a jquery datePicker button image unclickable

  - by Farzana

  I have a jquery UI datePicker in my page. I have a text box on which the date is displayed. The code is: $("#cal").datepicker({ minDate: new Date(), defaultDate: new Date(), buttonImage: '/images/calendar.gif', constrainInput: false, closeText: 'Close', showButtonPanel: true, showButtonText: 'Choose a date', buttonImageOnly : true, showOn : 'button' }); $("#till").datepicker('setDate', today); I want to disable this on some conditions. I use the following code to disable: $("#cal").datePicker('disable'); It blacks out the text box but the image is still clickable. The problem is in IE, the date picker pop up comes up but does not close when the image button associated with the date picker is clicked. I also tried to bind a onclick function with the image to make it non-clickable. But that does not work as well. How can make the date picker image button non-clickable when the date picker is disabled. Any help would be appreciated. Thanks, Farzana
