• URL Rewrite problem. (Many directory)

  - by marharépa

  Hello! I'd like to make a htaccess file, which can make a good structure for my websites. My .htaccess is now: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !\.(jpg|jpeg|gif|png|css|js|pl|txt)$ RewriteCond %{REQUEST_URI} !^/admin/* RewriteRule ^(.*)$ index.php?q=$1 [QSA] (based on Sombat's comment) And I want to make this, with it: for every elements but (jpg|jpeg|gif|png|css|js|pl|txt) if domain.xx/admin redirect to the domain.xx/admin directory and don't make a rewrite at all i mean: let me use domain.xx/admin/index.php?asd=1&asdd=2 else rewrite everything as rule one, to index.php. Thanks for the help.

• Java: BufferedImage from raw BMP file format data

  - by Victor

  Hello there. I've got BMP file's raw pixels table in byte[], it's structure is: (b g r) (b g r) ... (b g r) padding ... (b g r) (b g r) ... (b g r) padding Where r, g, b are byte each, padding is to round row length up to a multiple of 4 bytes. So, how can I create new BufferedImage from this raw data without copying, just using this raw data? I took a look at creating BufferedImage from DataBuffer, but I just didn't get it. Unfortunately ImageIO is not allowed in my situation.

• OpenGL index buffer object with additional data

  - by muksie

  I have a large set of lines, which I render from a vertex buffer object using glMultiDrawArrays(GL_LINE_STRIP, ...); This works perfectly well. Now I have lots of vertex pairs which I also have to visualize. Every pair consists of two vertices on two different lines, and the distance between the vertices is small. However, I like to have the ability to draw a line between all vertex pairs with a distance less than a certain value. What I like to have is something like a buffer object with the following structure: i1, j1, r1, i2, j2, r2, i3, j3, r3, ... where the i's and j's are indices pointing to vertices and the r's are the distances between those vertices. Thus every vertex pair is stored as a (i, j, r) tuple. Then I like to have a (vertex) shader which only draws the vertex pairs with r < SOME_VALUE as a line. So my question is, what is the best way to achieve this?

• mysql left join

  - by user1019538

  I have two table one is index and another is the price structure as under table : index : column : trandate ,indexcode Table : price : Column: trandate,symbol,price i want to know the missing price. I issue the query select i.trandate,i.indexcode,p.trandate,p.price from index i left join price p on i.trandate = p.trandate where p.symbol='ABC' and indexcode="New" the above query does not show the null date even though various price in missing in price table. Only reason i understand is that the index table does not have the symbol field that's why...but as per theory if you want to show all the rows of one table and only the match value of another table then use the left or right join query...please anybody can help

• Getting plane slices from array data

  - by umanga

  Greetings all, I read 3d grid data (from multiple TIF images) into a structure as follows : typedef struct VolumeData{ int nx; int ny; int nz; unsigned char *data; // size is nx*ny*nz } Now I want to get the plane slices from this 1-D grid data: eg: unsigned char* getXYPlaneStack(VolumeData *vol,int z); I could implement above function because the *data array stores image stack. But i am having difficult time implement along the other axes: unsigned char* getYZPlaneStack(VolumeData *vol,int x); and unsigned char* getXZPlaneStack(VolumeData *vol,int y); any easy algorithm for this? thanks in advance.

• Cake PHP Error: Make sure you have created index.ctp (???)

  - by Louis Stephens

  I was just starting to learn cakephp today by going through a "blog tutorial". I created my blog_controller.php and then created a folder named 'blog' with the apps/views/ structure. The next step in the tutorial was to create the index.ctp file within the blog folder under views. In the tutorial it declares that all error messages should be gone. However, I still receive an error message: Error: The view for BlogController::index() was not found. Error: Confirm you have created the file: /Users/trippstephens/Dropbox/cakephp-cakephp1x-348e5f0/app/views/blog/index.ctp For the life of me, I can not figure out what I have done wrong. I am running cakephp under MAMP and it "installed" successfully. Any help would be appreciated.

• phpunit - generate tests for all the classes from a directory

  - by joe

  Hi! I have a directoy structure, and all the classes of the business logic are placed in the app_dir/lib/ directory. I would like to generate unit tests for all the classes from this lib/ folder. The problem is, that I haven't found any option to specify the source directory, only the source file: from app_dir: phpunit --skeleton-class lib/ Error: "lib/.php" could not be opened. Is it the only solution to write my own php script, which iterates through the /lib folder and calls the skeleton generator for every file found? And how can I specify the output folder, where all the generated test files are placed? Thanx, Joe

• Can I improve performance by refactoring SQL commands into classes?

  - by Matthew Jones

  Currently, my entire website does updating from SQL parameterized queries. It works, we've had no problems with it, but it can occasionally be very slow. I was wondering if it makes sense to refactor some of these SQL commands into classes so that we would not have to hit the database so often. I understand hitting the database is generally the slowest part of any web application For example, say we have a class structure like this: Project (comprised of) Tasks (comprised of) Assignments Where Project, Task, and Assignment are classes. At certain points in the site you are only working on one project at a time, and so creating a Project class and passing it among pages (using Session, Profile, something else) might make sense. I imagine this class would have a Save() method to save value changes. Does it make sense to invest the time into doing this? Under what conditions might it be worth it?

• Loop through custom template hooking thing

  - by tarnfeld

  Hi, I am building a template system for emailing people that currently works in the format of: $array['key1'] = "text; $array['key2'] = "more text"; <!--key1--> // replaced with *text* <!--key2--> // replaced with *more text* For this particular project I have a nested array with this kind of structure: $array['object1']['nest1']['key1'] = "text"; $array['object2']['next1']['key1'] = "more text"; <!--[object1][nest1][key1]--> // replaced with *text* <!--[object2][nest1][key1]--> // replaced with *more text* What would be the best way to do this in PHP? I thought I could loop through the arrays but then I just lost my trail of thought and got lost in what I was doing! All help would be appreciated!! Thanks

• Mocha expects method

  - by Masha

  So my situation is: I have a 2 modules that have the same structure like that: module Module1 class Config def fee_rate 2 end end end So, say, Module2 would have class Config with the method fee_rate, just with a different value (those are actually implemented in a rails engine, but it shouldn't matter) and then my model can use either Module1 or Module2 to get the fee rate value like that: def config @config ||= "#{module_name.titleize}::Config".constantize.new @config end def get_value config.get_fee * some_other_value end What I'm trying to test is if get_fee function was called on the correct class: "#{model.module_name.titleize}::Config".constantize.any_instance.expects(:get_fee).at_least_once model.get_value and on the line when I call get_value I get the following error - undefined method `*' for nil:NilClass. I'm completely lost now, so I'd appreciate any help and ideas.

• Divide numpy array

  - by BandGap

  Hi all I have some data represented in a 1300x1341 matrix. I would like to split this matrix in several pieces (e.g. 9) so that I can loop over and process them. The data needs to stay ordered in the sense that x[0,1] stays below (or above if you like) x[0,0] and besides x[1,1]. Just like if you had imaged the data, you could draw 2 vertical and 2 horizontal lines over the image to illustrate the 9 parts. If I use numpys reshape (eg. matrix.reshape(9,260,745) or any other combination of 9,260,745) it doesn't yield the required structure since the above mentioned ordering is lost... Did I misunderstand the reshape method or can it be done this way? What other pythonic/numpy way is there to do this?

• How to replace&add the dataframe element by another dataframe in Python Pandas?

  - by bigbug

  Suppose I have two data frame 'df_a' & 'df_b' , both have the same index structure and columns, but some of the inside data elements are different: >>> df_a sales cogs STK_ID QT 000876 1 100 100 2 100 100 3 100 100 4 100 100 5 100 100 6 100 100 7 100 100 >>> df_b sales cogs STK_ID QT 000876 5 50 50 6 50 50 7 50 50 8 50 50 9 50 50 10 50 50 And now I want to replace the element of df_a by element of df_b which have the same (index, column) coordinate, and attach df_b's elements whose (index, column) coordinate beyond the scope of df_a .

• Python __setattr__ and __getattr__ for global scope?

  - by KT

  Suppose I need to create my own small DSL that would use Python to describe a certain data structure. E.g. I'd like to be able to write something like f(x) = some_stuff(a,b,c) and have Python, instead of complaining about undeclared identifiers or attempting to invoke the function some_stuff, convert it to a literal expression for my further convenience. It is possible to get a reasonable approximation to this by creating a class with properly redefined __getattr__ and __setattr__ methods and use it as follows: e = Expression() e.f[e.x] = e.some_stuff(e.a, e.b, e.c) It would be cool though, if it were possible to get rid of the annoying "e." prefixes and maybe even avoid the use of []. So I was wondering, is it possible to somehow temporarily "redefine" global name lookups and assignments? On a related note, maybe there are good packages for easily achieving such "quoting" functionality for Python expressions?

• C#.NET: FTP Several Files

  - by Steve Kiss

  Hi, I have what would seem like a common problem, but I cannot find an appropriate solution on any forums. I need to FTP an entire directory structure using .NET. I have found several code examples all of which show how you can FTP a single file by creating an FtpWebRequest object. Unfortunately, there is no information on how to deal with several files. Do I simply create a FtpWebRequest object for every single file? Any help would be appreciated. Thanks

• Java application if/case recommendation

  - by Jesse

  I am writing an application for a Java course. I am a complete beginner and am just going off material I have learned from the course and from the web. The application is exhibiting some behavior and I am not sure what is causing it. The application is GUI based and does calculations on user input. For the action listener section, I have a set of If statements such as: "if this button do this if this button do this" All in a row like that. It seems as if the application is running ALL the if statements instead of running the one that corresponds with the button pressed. Would I be better off using a case/switch structure for this sort of thing? I can post my code if necessary, I am new around this site and am not sure if that thing is acceptable.

• How to use C# nested structures to access tree of data

  - by zotty

  I'm importing some XML to C#, and want to be able to access data from the XML in the form of what I think is a nested structure. (I may be wrong!) What I have in my XML is in the following form: <hardwareSettings initial="true> <cameraSettings width="1024" height="768" depth="8" /> <tiltSettings theta="35" rho="90"> </hardwareSettings> I can import each setting alright, so I have them all in individual ints, but I would like to be able to access it in the form int x=hardwaresettings.camerasettings.width; int rho=hardwaresettings.tiltsettings.rho; I've tried various arrangements of structs within structs, but I don't seem able to cast a new object (hardwaresettings) that contains the appropriate children (camerasettings.width & tiltsettings.rho). Sorry if I'm not using the right lingo... I'm reading myself in circles here!

• Mysql: create index on 1.4 billion records

  - by SiLent SoNG

  I have a table with 1.4 billion records. The table structure is as follows: CREATE TABLE text_page ( text VARCHAR(255), page_id INT UNSIGNED ) ENGINE=MYISAM DEFAULT CHARSET=ascii The requirement is to create an index over the column text. The table size is about 34G. I have tried to create the index by the following statement: ALTER TABLE text_page ADD KEY ix_text (text) After 10 hours' waiting I finally give up this approach. Is there any workable solution on this problem? UPDATE: the table is unlikely to be updated or inserted or deleted. The reason why to create index on the column text is because this kind of sql query would be frequently executed: SELECT page_id FROM text_page WHERE text = ?

• Python | How to create dynamic and expandable dictionaries

  - by MMRUser

  I want to create a Python dictionary which holds values in a multidimensional accept and it should be able to expand, this is the structure that the values should be stored :- userdata = {'data':[{'username':'Ronny Leech','age':'22','country':'Siberia'},{'username':'Cronulla James','age':'34','country':'USA'}]} Lets say I want to add another user def user_list(): users = [] for i in xrange(5, 0, -1): lonlatuser.append(('username','%s %s' % firstn, lastn)) lonlatuser.append(('age',age)) lonlatuser.append(('country',country)) return dict(user) This will only returns a dictionary with a single value in it (since the key names are same values will overwritten).So how do I append a set of values to this dictionary. Note: assume age, firstn, lastn and country are dynamically generated. Thanks.

• Django: request object to template context transparancy

  - by anars

  Hi! I want to include an initialized data structure in my request object, making it accessible in the context object from my templates. What I'm doing right now is passing it manually and tiresome within all my views: render_to_response(...., ( {'menu': RequestContext(request)})) The request object contains the key,value pair which is injected using a custom context processor. While this works, I had hoped there was a more generic way of passing selected parts of the request object to the template context. I've tried passing it by generic views, but as it turns out the request object isn't instantiated when parsing the urlpatterns list.

  Hi guys, Need a guide line .... I am trying to write a personal blog. What is the standard structure for for input for the post. I am trying the format like: This is the simple text And I am [b] bold text[/b].

And What is the right method to parse this kind of post? Shall I use regular expression to parse this or there is another standard for this. If the above mentioned format is not the right way for storage, then what it could be? Thanks

• How do I find resources in a .jar on the classpath?

  - by Brabster

  If I have a collection of resource files in a directory on my classpath, I can enumerate them using ClassLoader.getResources(location). For example if I have /mydir/myresource.properties on the classpath, I can call the classloader's getResources("mydir") and get an enumeration of URLs containing myresource.properties. When I pack up the exact same resources into a .jar, I don't get anything in the enumeration of URLs when I make the call. I've only replaced the folder structure with a jar containing those folders (it's a webapp, so the jar is going into /WEB-INF/lib). I've also got a number of other calls using getResourceAsStream(location) to get other resources individually by name and they're all working fine. What's different about enumerating resources when the resources are in a .jar?

• Use CSS selectors to collect HTML elements from a streaming parser (e.g. SAX stream)

  - by Jakub Narebski

  How to parse CSS (CSS3) selector and use it (in jQuery-like way) to collect HTML elements not from DOM (from tree structure), but from stream (e.g. SAX), i.e. using sequential access parser? Are there CSS selectors that need access to DOM (Wikipedia SAX page says that XPath selectors "need to be able to access any node at any time in the parsed XML tree")? I am most inetersted in implementing selector combinators, e.g. 'A B' descendant selector. I prefer solutions describing algorithm, or in Perl.

• A submenu (`ToolStripMenuItem`) does not show automatically.

  - by czuk

  I have encountered strange problem with a three-level context menu. In some situation the sub menu does not show automatically. I have following structure of the menu: * AAA - level 1 * BBB - level 1 * CCC - level 2 * xxx - level 3 * yyy - level 3 * DDD - level 2 * zzz - level 3 * vvv - level 3 I start from a menu with two option AAA and BBB. After I move the cursor over BBB the second-level menu appears with two other options CCC and DDD. So far OK. Now, when I quickly move the cursor over DDD the third-level sub menu does not show up, but when I move the cursor back to CCC the sub menu shows up, and when I go back to DDD then the sub menu also shows. Why it does not show at first time? Have you ever encountered such a problem? I fixed the problem with MouseEnter and MouseLeave events, but I still wonder why it does not work properly without the events.

• Extract string that is delimited with constant and ends with two numbers (numbers have to be included)

  - by Edmon

  I have a text that contains string of a following structure: text I do not care about, persons name followed by two IDs. I know that: a person's name is always preceded by XYZ code and that is always followed by two, space separated numbers. Name is not always just a last name and first name. It can be multiple last or first names (think Latin american names). So, I am looking to extract string that follows the constant XYZ code and that is always terminated by two separate numbers. You can say that my delimiter is XYZ and two numbers, but numbers need to be part of the extracted value as well. From blah, blah XYZ names, names 122322 344322 blah blah I want to extract: names, names 122322 344322 Would someone please advise on the regular expression for this that would work with Python's re package.
