  • recaptcha still submits form when one word invalid

    - by luckytaxi
    Um so I was in for a little bit of a surprise tonight. I spent a good 20 mins trying to figure out why I was able to submit a form knowing that what I entered into the recaptcha field was invalid. Is it true that you don't need to input the exact words it displays? If it shows me two words and I misspelled one of the words, I still pass validation? Same goes if "hello world" and I input "hell man" it still works.

  • Removing last word from FOREACH loop

    - by Stoosh
    I'm building a basic function, which builds out Mysql WHERE clauses based on how many are in the array. $array = array('id' => '3', 'name' => 'roger'); $sql = "SELECT * FROM table WHERE "; foreach ($array as $k => $v) { $sql .= $k . ' = ' . $v . ' AND '; } which will output SELECT * FROM table WHERE id = 3 AND name = roger AND However obviously I don't want that last AND, how do I go about removing it from the string? Thanks

  • detecting pauses in a spoken word audio file using pymad, pcm, vad, etc

    - by james
    First I am going to broadly state what I'm trying to do and ask for advice. Then I will explain my current approach and ask for answers to my current problems. Problem I have an MP3 file of a person speaking. I'd like to split it up into segments roughly corresponding to a sentence or phrase. (I'd do it manually, but we are talking hours of data.) If you have advice on how to do this programatically or for some existing utilities, I'd love to hear it. (I'm aware of voice activity detection and I've looked into it a bit, but I didn't see any freely available utilities.) Current Approach I thought the simplest thing would be to scan the MP3 at certain intervals and identify places where the average volume was below some threshold. Then I would use some existing utility to cut up the mp3 at those locations. I've been playing around with pymad and I believe that I've successfully extracted the PCM (pulse code modulation) data for each frame of the mp3. Now I am stuck because I can't really seem to wrap my head around how the PCM data translates to relative volume. I'm also aware of other complicating factors like multiple channels, big endian vs little, etc. Advice on how to map a group of pcm samples to relative volume would be key. Thanks!

  • Word 2007, Open XML - embedding an image

    - by agnieszka
    Do you know what basic information MUST include a paragraph (w:p) in document.xml inside a *.docx document, that specifies an image? I do know there must be <a:blip r:embed="rId4" /> specifing the relation id, but what else? It's very hard to find it in google and experimenting with cutting out tags from a ready document or reading the specification takes a lot of time. An example with all the required tags would be greatly appreciated.

  • Abusing the word "library"

    - by William Pursell
    I see a lot of questions, both here on SO and elsewhere, about "maintaining common libraries in a VCS". That is, projects foo and bar both depend on libbaz, and the questioner is wondering how they should import the source for libbaz into the VCS for each project. My question is: WTF? If libbaz is a library, then foo doesn't need its source code at all. There are some libraries that are reasonably designed to be used in this manner (eg gnulib), but for the most part foo and bar ought to just link against the library. I guess my thinking is: if you cut-and-paste source for a library into your own source tree, then you obviously don't care about future updates to the library. If you care about updates, then just link against the library and trust the library maintainers to maintain a stable API. If you don't trust the API to remain stable, then you can't blindly update your own copy of the source anyway, so what is gained? To summarize the question: why would anyone want to maintain a copy of a library in the source code for a project rather than just linking against that library and requiring it as a dependency? If the only answer is "don't want the dependency", then why not just distribute a copy of the library along with your app, but keep them totally separate?

  • Scaled live iPhone Camera view in center, "CGAffineTransformTranslate" not working

    - by Gavin
    Hi, I have a little problem which I could not solve. I really hope someone can help me with that. I wanted to resize the live camera view and place it in the center, using the following code below: picker.cameraViewTransform = CGAffineTransformScale(picker.cameraViewTransform, 0.5, 0.56206); picker.cameraViewTransform = CGAffineTransformTranslate(picker.cameraViewTransform, 80, 120); But all I got was a scaled 1/2 sized view on the top left of the screen. It seems as though "CGAffineTransformTranslate" does nothing at all. The translation didn't work even when I used: picker.cameraViewTransform = CGAffineTransformMake(1, 0, 0, 1, 80, 120); The translation portion seems to have no effect on the live camera view. Hope someone can enlighten me. Thanks.

I know that I can add to out of box ribbons by specifying the Tabs idMSo value but how do I do that for a custom ribbon tab. I have already tried the ID value of the custom ribbon, but it juts duplicates the ribbon? have also tried idMso and idQ attributes passing in the required custom tab Id but no success. I can add it to out of box tab group by specifying the idMso value but not to custom tab regards

  • Android PixelFormat per device

    - by Tobias Domhan
    analogous to this thread: stackoverflow.com/questions/2093594/opengl-extensions-available-on-different-android-devices I would like to collect the different PixelFormats the android devices use. To find out you must do the following: Parameters camParams = camera.getParameters(); int format = camParams.getPreviewFormat(); Now you got to find the number in the following list: developer.android.com/reference/android/graphics/PixelFormat.html#A_8 How to generally open the camera is described here: developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/CameraPreview.html I'll have a start: device: T-mobile G1 / HTC Dream android: 1.6 (cyanogen mod) format: YCbCr_420_SP so what formats do your android phones use? thanks in advance :D

  • Exclude all normal alphanumeric character from a mixed chinese-and-alphanumeric character word list

    - by Christine
    I have a list of chinese characters and normal alphanumeric characters, mixed together, and I want to get rid of any element that contains an alphanumeric character. Is there a simple way to do this? If I simply exclude any element that contains an alphanumeric character, I get no result because the chinese characters (in utf-8) are similarly affected. I also tried [w for w in fourchar if w.startswith("\x")] to try to get the chinese characters but I'm not sure if that's valid at all. I'm having difficulty figuring out what the alphanumeric characters are in unicode. Thanks for any help!

  • Vim, LaTeX, word-wrapping, and version control

    - by Bkkbrad
    I'm writing a LaTeX document in vim, and I have it hard wrapping at 80 characters to make reading easier. However, this causes problems with tracking changes with in version control. For example, inserting "Lorem ipsum" at the beginning of this text: 1 Dolor sit amet, consectetur adipiscing elit. Phasellus bibendum lobortis lectus 2 quis porta. Aenean vestibulum magna vel purus laoreet at molestie massa 3 suscipit. Vestibulum vestibulum, mauris nec convallis ultrices, tellus sapien 4 ullamcorper elit, dignissim consectetur justo tellus et nunc. results in: 1 Lorum ipsum dolor sit amet, consectetur adipiscing elit. Phasellus bibendum 2 lobortis lectus quis porta. Aenean vestibulum magna vel purus laoreet at 3 molestie massa suscipit. Vestibulum vestibulum, mauris nec convallis ultrices, 4 tellus sapien ullamcorper elit, dignissim consectetur justo tellus et nunc. When I review this change in git, it tells me that all the lines of the paragraph have changed because of the wrapping, even though only one semantic change has occurred. One way around this problem is to have every sentence on its own line. This looks the same in the rendered document, but the source now is harder to read, because each line has quite a different line length: 1 Lorum ipsum dolor sit amet, consectetur adipiscing elit. 2 Phasellus bibendum lobortis lectus quis porta. 3 Aenean vestibulum magna vel purus laoreet at molestie massa suscipit. 4 Vestibulum vestibulum, mauris nec convallis ultrices, tellus sapien ullamcorper elit, dignissim consectetur justo tellus et nunc. (If I soft wrap at 80, things still look bad, just in a different way.) Is it possible to have my text on disk with one newline per sentence, but display and edit it in vim as if the text of each paragraph was one long line, soft wrapped at 80 characters? I assume it requires some vim-foo rather than tweaking git or LaTeX.

  • Best way to split a string by word (SQL Batch separator)

    - by Paul Kohler
    I have a class I use to "split" a string of SQL commands by a batch separator - e.g. "GO" - into a list of SQL commands that are run in turn etc. ... private static IEnumerable<string> SplitByBatchIndecator(string script, string batchIndicator) { string pattern = string.Concat("^\\s*", batchIndicator, "\\s*$"); RegexOptions options = RegexOptions.Compiled | RegexOptions.IgnoreCase | RegexOptions.Multiline; foreach (string batch in Regex.Split(script, pattern, options)) { yield return batch.Trim(); } } My current implementation uses a Regex with yield but I am not sure if it's the "best" way. It should be quick It should handle large strings (I have some scripts that are 10mb in size for example) The hardest part (that the above code currently does not do) is to take quoted text into account Currently the following SQL will incorrectly get split: var batch = QueryBatch.Parse(@"-- issue... insert into table (name, desc) values('foo', 'if the go is on a line by itself we have a problem...')"); Assert.That(batch.Queries.Count, Is.EqualTo(1), "This fails for now..."); I have thought about a token based parser that tracks the state of the open closed quotes but am not sure if Regex will do it. Any ideas!?

  • Automatically capitalize first letter of first word in a new sentence in LaTeX

    - by Tom Hagen
    I know one of LaTeX's bragging points is that it doesn't have this Microsoftish behavior. Nevertheless, it's sometimes useful. LaTeX already adds an extra space after you type a (non-backslashed) period, so it should be possible to make it automatically capitalize the following letter as well. Is there an obvious way to write a macro that does this, or is there a LaTeX package that does it already?

  • XNA - Mouse coordinates to word space transformation

    - by Gabriel Butcher
    I have a pretty annoying problem. I would like to create a drawing program, using winform + XNA combo. The most important part would be to transform the mouse position into the XNA drawn grid - I was able to make it for the translations, but it only work if I don't zoom in - when I do, the coordinates simply went horrible wrong. And I have no idea what I doing wrong. I tried to transform with scaling matrix, transform with inverse scaling matrix, multiplying with zoom, but none seems to work. In the beginning (with zoom value = 1) the grid starts from (0,0,0) going to (Width, Height, 0). I was able to get coordinates based on this grid as long as the zoom value didn't changed at all. I using a custom shader, with orthographic projection matrix, identity view matrix, and the transformed world matrix. Here is the two main method: internal void Update(RenderData data) { KeyboardState keyS = Keyboard.GetState(); MouseState mouS = Mouse.GetState(); if (ButtonState.Pressed == mouS.RightButton) { camTarget.X -= (float)(mouS.X - oldMstate.X) / 2; camTarget.Y += (float)(mouS.Y - oldMstate.Y) / 2; } if (ButtonState.Pressed == mouS.MiddleButton || keyS.IsKeyDown(Keys.Space)) { zVal += (float)(mouS.Y - oldMstate.Y) / 10; zoom = (float)Math.Pow(2, zVal); } oldKState = keyS; oldMstate = mouS; world = Matrix.CreateTranslation(new Vector3(-camTarget.X, -camTarget.Y, 0)) * Matrix.CreateScale(zoom / 2); } internal PointF MousePos { get { Vector2 mousePos = new Vector2(Mouse.GetState().X, Mouse.GetState().Y); Matrix trans = Matrix.CreateTranslation(new Vector3(camTarget.X - (Width / 2), -camTarget.Y + (Height / 2), 0)); mousePos = Vector2.Transform(mousePos, trans); return new PointF(mousePos.X, mousePos.Y); } } The second method should return the coordinates of the mouse cursor based on the grid (where the (0,0) point of the grid is the top-left corner.). But is just don't work. I deleted the zoom transformation from the matrix trans, as I didnt was able to get any useful result (most of the time, the coordinates was horrible wrong, mostly many thousand when the grid's size is 500x500). Any idea, or suggestion? I trying to solve this simple problem for two days now :\

  • Checking For Word Wrap In Table Column

    - by Sparafusile
    I'm writing part of a web page that allows a user to build a table and fill it with information. In the course of building the table, the user will be adding additional columns with headers. I'd like to code it so when the combined width of all the headers causes one of them to wrap that the table columns switch to using vertical text (writing-mode: tb-rl). Is there any way, using JavaScript, to determine if the contents of a specific cell have wrapped? Thanks, Spara

  • IE7 contentEditable word wrapping

    - by Iker Jimenez
    I have the following code: <html> <style type="text/css"> DIV { display:inline; border: solid red 1px; } .editable { background:yellow; } </style> <div class="editable" contentEditable="true"> This is test text. This is test text.This is test text.This is test text.This is test text.Thihis is test text.This is test text.</div> <div class="editable" contentEditable="true"> short </div> <div class="editable" contentEditable="true"> This is test text.This is test text.This is test text.his is test text.Thihis is test text.Thihis is test text.Thihis is test text.Thi </div> And I need IE7 (IE6 not needed and FF3.x works fine) to wrap the text correctly, which it does if I remove the contentEditable="true" from the divs. Just try this code with and without contentEditable and you'll see what I mean. Make the browser window small enough so you see how the text wraps. Thanks.
