  • Camera pics not appearing in Gallery app

    - by Travis
    When I take pictures using android.hardware.camera and I save them to the following location /sdcard/dcim/camera/ they don't appear when I launch the gallery. Is there a process for getting them to show up in the gallery that I missed? I can see my images using a file explorer and know they have been saved.

  • jQuery Plugin Overwriting Parameters

    - by Travis
    Hey Everyone, This maybe a very mundane question, but this is the first jQuery plugin that I write and I'm a bit fuzzy on understanding the scope rules in Javascript. I'm trying to write an simple jQuery plugin that wraps around the Stack Overflow API. I'm starting off by trying to work with the Flair API. I wanted to make the plugin as configurable as possible so that you can easily pass it the domain and user id, and generate multiple Flairs. var superUser = $.jStackOverflow.flair({domain:"superuser.com", id: 30162, parentId:'#su-flair'}); var stackOverflow = $.jStackOverflow.flair({domain:"stackoverflow.com", id: 55954, parentId:'#so-flair'}); The problem is, when it makes the second call, its somehow using the correct domain and id parameters, but the parentId field that it's using in the callback function to create the html, is using the first parameter. You can see the plugin here and the html here

  • How to setup IIS extranet site for unsecure access internally and secure (ssl) access from external

    - by Scott Travis
    I have an enterprise extranet application that is accessed using an internal DNS entry for the machine name by employees and via a domain name that has SSL configured externally. Currently remote sessions can use either the http or https address, but we want to turn off http access for external sessions while leaving it enabled for internal users. The site is written in ASP classic and running on IIS on Windows 2003 Server. Thank you for your time.

  • How do I make the following interaction with mySQL more efficient?

    - by Travis
    I've got an array that contains combinations of unique MySql IDs: For example: [ [1,10,11], [2,10], [3,10,12], [3,12,13,20], [4,12] ] In total there are a couple hundred different combinations of IDs. Some of these combinations are "valid" and some are not. For example, [1,10,11] may be a valid combination, whereas [3,10,12] may be invalid. Combinations are valid or invalid depending on how the data is arranged in the database. Currently I am using a SELECT statement to determine whether or not a specific combination of IDs is valid. It looks something like this: SELECT id1 FROM table WHERE id2 IN ($combination) GROUP BY id1 HAVING COUNT(distinct id2) = $number ...where $combination is one possible combination of IDs (eg 1,10,11) and $number is the number of IDs in that combination (in this case, 3). An invalid combination will return 0 rows. A valid combination will return 1 or more rows. However, to solve the entire set of possible combinations means looping a couple hundred SELECT statements, which I would rather not be doing. I am wondering: Are there any tricks for making this more efficient? Is it possible to submit the entire dataset to mySQL in one go, and have mySQL iterate through it? Any suggestions would be much appreciated. Thanks in advance!

  • Java appending XML data

    - by Travis
    I've already read through a few of the answers on this site but none of them worked for me. I have an XML file like this: <root> <character> <name>Volstvok</name> <charID>(omitted)</charID> <userID>(omitted)</userID> <apiKey>(omitted)</apiKey> </character> </root> I need to add another <character> somehow. I'm trying this but it does not work: public void addCharacter(String name, int id, int userID, String apiKey){ Element newCharacter = doc.createElement("character"); Element newName = doc.createElement("name"); newName.setTextContent(name); Element newID = doc.createElement("charID"); newID.setTextContent(Integer.toString(id)); Element newUserID = doc.createElement("userID"); newUserID.setTextContent(Integer.toString(userID)); Element newApiKey = doc.createElement("apiKey"); newApiKey.setTextContent(apiKey); //Setup and write newCharacter.appendChild(newName); newCharacter.appendChild(newID); newCharacter.appendChild(newUserID); newCharacter.appendChild(newApiKey); doc.getDocumentElement().appendChild(newCharacter); }

  • "Downloading" a computed value form JavaScript

    - by Travis Jensen
    I'm hoping you can prove me wrong here (please, please, please! ;). I have a situation where I need to download encrypted data from a Server D (for "Data"). Server K (for "Key") has the encryption key. For security sake, I would really prefer that Server D never know the key that Server K knows. What I want is my client (e.g. your browser) to connect to Server D for the data and Server K for the key and doe the decryption locally so the unencrypted stuff never leaves your computer. I can do this fine for text areas in the dom by replacing the contents of the HTML. However, sometimes, I would like to do larger files that I stream to the file system. For instance, perhaps I want to encrypt a movie and decrypt it and stream the contents to the my video player. I am not a JavaScript guru by any stretch, especially when it comes to the edge cases of things like the security sandbox. For Small D, I can handle the decryption, but I don't know how to save the decrypted file. Large D seems problematic as memory runs out. Anybody have any ideas that don't involve native plugins? Thanks!

  • After adding a UILabel to my view, how do I delete it?

    - by Travis
    I have added a UILabel to my view programmatically like this: myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 30.0f)]; myLabel.center = CGPointMake(160.0f, 120.0f); myLabel.backgroundColor = [UIColor clearColor]; myLabel.textColor = [UIColor whiteColor]; myLabel.font = [UIFont fontWithName:@"Helvetica" size: 18.0]; myLabel.textAlignment = UITextAlignmentCenter; myLabel.text = @"Hello"; [self.myView addSubview:myLabel]; To add a label to my view. What I can't seem to find out is once I'm done w/ the label (at a future point) how can I delete it from the view? [myLabel release] doesn't seem to work which I think makes sense because the view it's added to probably retained it's over reference. So what is the best practice?

  • Zipping with padding in Haskell

    - by Travis Brown
    A couple of times I've found myself wanting a zip in Haskell that adds padding to the shorter list instead of truncating the longer one. This is easy enough to write. (Monoid works for me here, but you could also just pass in the elements that you want to use for padding.) zipPad :: (Monoid a, Monoid b) => [a] -> [b] -> [(a, b)] zipPad xs [] = zip xs (repeat mempty) zipPad [] ys = zip (repeat mempty) ys zipPad (x:xs) (y:ys) = (x, y) : zipPad xs ys This approach gets ugly when trying to define zipPad3. I typed up the following and then realized that of course it doesn't work: zipPad3 :: (Monoid a, Monoid b, Monoid c) => [a] -> [b] -> [c] -> [(a, b, c)] zipPad3 xs [] [] = zip3 xs (repeat mempty) (repeat mempty) zipPad3 [] ys [] = zip3 (repeat mempty) ys (repeat mempty) zipPad3 [] [] zs = zip3 (repeat mempty) (repeat mempty) zs zipPad3 xs ys [] = zip3 xs ys (repeat mempty) zipPad3 xs [] zs = zip3 xs (repeat mempty) zs zipPad3 [] ys zs = zip3 (repeat mempty) ys zs zipPad3 (x:xs) (y:ys) (z:zs) = (x, y, z) : zipPad3 xs ys zs At this point I cheated and just used length to pick the longest list and pad the others. Am I overlooking a more elegant way to do this, or is something like zipPad3 already defined somewhere?

  • How to represent and insert into an ordered list in SQL?

    - by Travis
    I want to represent the list "hi", "hello", "goodbye", "good day", "howdy" (with that order), in a SQL table: pk | i | val ------------ 1 | 0 | hi 0 | 2 | hello 2 | 3 | goodbye 3 | 4 | good day 5 | 6 | howdy 'pk' is the primary key column. Disregard its values. 'i' is the "index" that defines that order of the values in the 'val' column. It is only used to establish the order and the values are otherwise unimportant. The problem I'm having is with inserting values into the list while maintaining the order. For example, if I want to insert "hey" and I want it to appear between "hello" and "goodbye", then I have to shift the 'i' values of "goodbye" and "good day" (but preferably not "howdy") to make room for the new entry. So, is there a standard SQL pattern to do the shift operation, but only shift the elements that are necessary? (Note that a simple "UPDATE table SET i=i+1 WHERE i=3" doesn't work, because it violates the uniqueness constraint on 'i', and also it updates the "howdy" row unnecessarily.) Or, is there a better way to represent the ordered list? I suppose you could make 'i' a floating point value and choose values between, but then you have to have a separate rebalancing operation when no such value exists. Or, is there some standard algorithm for generating string values between arbitrary other strings, if I were to make 'i' a varchar? Or should I just represent it as a linked list? I was avoiding that because I'd like to also be able to do a SELECT .. ORDER BY to get all the elements in order.

  • Is there a DOS command for verifying what version of .NET is installed

    - by Travis
    I have set of scripts for doing scripted installs. You can use the scripts on any server 2008 machine. However, I need to check if .NET 3.5 has been installed (before the scripts run) using a dos batch file. Is that possible? I know I can check if a file in the C:\WINDOWS\Microsoft.NET\Framework\v3.5 exists, but it would be nice to have something a little more reliable. I would like to check if it's actually installed, not just if the dir/file exists. Hope that makes sense. Thanks in advance.

  • C++ Returning Multiple Items

    - by Travis Parks
    I am designing a class in C++ that extracts URLs from an HTML page. I am using Boost's Regex library to do the heavy lifting for me. I started designing a class and realized that I didn't want to tie down how the URLs are stored. One option would be to accept a std::vector<Url> by reference and just call push_back on it. I'd like to avoid forcing consumers of my class to use std::vector. So, I created a member template that took a destination iterator. It looks like this: template <typename TForwardIterator, typename TOutputIterator> TOutputIterator UrlExtractor::get_urls( TForwardIterator begin, TForwardIterator end, TOutputIterator dest); I feel like I am overcomplicating things. I like to write fairly generic code in C++, and I struggle to lock down my interfaces. But then I get into these predicaments where I am trying to templatize everything. At this point, someone reading the code doesn't realize that TForwardIterator is iterating over a std::string. In my particular situation, I am wondering if being this generic is a good thing. At what point do you start making code more explicit? Is there a standard approach to getting values out of a function generically?

  • Yet another Haskell vs. Scala question

    - by Travis Brown
    I've been using Haskell for several months, and I love it—it's gradually become my tool of choice for everything from one-off file renaming scripts to larger XML processing programs. I'm definitely still a beginner, but I'm starting to feel comfortable with the language and the basics of the theory behind it. I'm a lowly graduate student in the humanities, so I'm not under a lot of institutional or administrative pressure to use specific tools for my work. It would be convenient for me in many ways, however, to switch to Scala (or Clojure). Most of the NLP and machine learning libraries that I work with on a daily basis (and that I've written in the past) are Java-based, and the primary project I'm working for uses a Java application server. I've been mostly disappointed by my initial interactions with Scala. Many aspects of the syntax (partial application, for example) still feel clunky to me compared to Haskell, and I miss libraries like Parsec and HXT and QuickCheck. I'm familiar with the advantages of the JVM platform, so practical questions like this one don't really help me. What I'm looking for is a motivational argument for moving to Scala. What does it do (that Haskell doesn't) that's really cool? What makes it fun or challenging or life-changing? Why should I get excited about writing it?

  • Reporting Android Application Crashes

    - by Travis
    I've noticed a couple of Android applications that seem to be using a 3rd party crash reporting tool. Has anyone seen this screen and do you know where I can find it? I started using http://code.google.com/p/android-remote-stacktrace/ but i rather not require internet permissions if I can use an intent to send emails.

  • clearTimeout not working in javascript autocomplete script

    - by Travis
    I am using the following code as part of an autocomplete script to avoid hammering the server with every keystroke: var that = this; textInput.bind("keyup", function() { clearTimeout(that.timer); that.timer = setTimeout (that.doStuff(), 2000); }); Unfortunately, this does not clear the old timers. They still all execute. Does anyone know what I'm missing? Thanks!

  • How to reference a specific object in an array of objects using jTemplates

    - by Travis
    I am using the excellent jTemplates plugin to generate content. Given a data object like this... var data = { name: 'datatable', table: [ {id: 1, name: 'Anne'}, {id: 2, name: 'Amelie'}, {id: 3, name: 'Polly'}, {id: 4, name: 'Alice'}, {id: 5, name: 'Martha'} ] }; ..I'm wondering if it is possible to directly specify an object in an array of objects using $T. (I'm hoping there is something like $T.table:3 available) Currently the only way I can think of to access a specific object in an array is to do something like this... {#foreach $T.table as record} {#if $T.record$iteration == 3} This is record 3! Name: {$T.record.name} {#/if} {#/for} However that seems clumsy... Any suggestions? Thanks

    In config.php, if i uncomment the following line $config->useGehsi(); Suddenly, when I load up a C# file, instead of showing the document, it's just a blank page. As soon as I comment out the code above, I'm able to see my C# file, but there's no syntax highlighting. Anyone have a solution to get GeSHi working with WebSVN when this kind of error occurs?

  • array or list into Oracle using cfprocparam

    - by Travis
    I have a list of values I want to insert into a table via a stored procedure. I figured I would pass an array to oracle and loop through the array but I don't see how to pass an array into Oracle. I'd pass a list but I don't see how to work with the list to turn it into an array using PL/SQL (I'm fairly new to PL/SQL). Am I approaching this the wrong way? Using Oracle 9i and CF8. TIA! EDIT Perhaps I'm thinking about this the wrong way? I'm sure I'm not doing anything new here... I figured I'd convert the list to an associative array then loop the array because Oracle doesn't seem to work well with lists (in my limited observation). I'm trying to add a product, then add records for the management team. -- product table productName = 'foo' productDescription = 'bar' ... ... etc -- The managementteam table just has the id of the product and id of the users selected from a drop down. The user IDs are passed in via a list like "1,3,6,20" How should I go about adding the records to the management team table?

  • Wordpress loop > unique loop renders slightly wrong results...

    - by Travis Neilson
    A few things to understand before my question will make sense: I use a hidden category called 'Unique' to specify if the post will use the single.php or a special one used for the unique ones. I want the index to act as a single: showing only one post, displaying next/prev post links, and comments also. I need the index.php to say if the post is in category 15 (unique) than <the_unique_content>, else; <the_default_content> My loop does all this, but the problem is that if the current post is unique, it also displays 1 additional post below the unique post. Here is the loop <?php $wp_query->is_single = true; ?> <?php $post_count = 0; ?> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <?php if ($post_count == 0) : ?> <?php if (in_category('15')) { ?> <?php the_content(); ?> <?php } else { ?> <?php the_content(); ?> <?php $post_count++; ?> Thanks for any help!

  • mod_rewrite in conjunction with "options indexes"

    - by Travis
    I have a directory ("files") where sub-directories and files are going to be created and stored over time. The directories also need to deliver a directory listing, using "options indexes", but only if a user is authenticated, and authorized. I have that part built, and working, by doing the following: <Directory /var/www/html/files> Options Indexes IndexOptions FancyIndexing SuppressHTMLPreamble HeaderName /includes/autoindex/auth.php </Directory> Now I need to take care of file delivery. To force authentication for files, I have built the following: RewriteCond %{REQUEST_URI} -f RewriteRule /files/(.*) /auth.php I also tried: RewriteCond %{REQUEST_URI} !-d RewriteRule /files/(.*) /auth.php Both directives are redirecting to auth.php when I request: foo.com/files/bar/ foo.com/files/bar/baz I am outputting the SERVER global on auth.php during testing and it is showing the requests as I made them (I thought Apache may have been doing something behind the scenes by adding something like "index.html" to the end with "Options Indexes" being on). Ideas?
