  • How do I correctly model data in SQL-based databases that have some columns in common, but also have

    - by Brandon Weiss
    For instance, let's say I have a User model. Users have things like logins, passwords, e-mail addresses, avatars, etc. But there are two types of Users that will be using this site, let's say Parents and Businesses. I need to store some different information for the Parents (e.g. childrens' names, domestic partner, salaries, etc.) than for the Businesses (e.g. industry, number of employees, etc.), but also some of it is the same, like logins and passwords. How do I correctly structure this in a SQL-based database? Thanks!

  • Automatic Deployment to Multiple Production Environments

    - by Brandon Montgomery
    I want to update an ASP .NET web application (including web.config file changes and database scripts) to multiple production environments - ideally with the click of a button. I do not have direct network connectivity to any of them. I think this means the application servers will have to "pull" the information required for updating the application, and run a script to update the application that resides on the server. Basically, I need a way to "publish" an update, and the servers see that update and automatically download and run it. I've thought about possibly setting up an SFTP server for publishing updates, and developing a custom tool which is installed on production environments which looks at the SFTP server every day and downloads application files if they are available. That would at least get the required files onto the servers, and I could use xcopy/robocopy and Migrator.NET to deploy the updates. Still not sure about config file changes, but that at least gets me somewhere. Is there any good solution for this scenario? Are there any tools that do this for you?

  • PHP Encrypt/Decrypt with TripleDes, PKCS7, and ECB

    - by Brandon Green
    I've got my encryption function working properly however I cannot figure out how to get the decrypt function to give proper output. Here is my encrypt function: function Encrypt($data, $secret) { //Generate a key from a hash $key = md5(utf8_encode($secret), true); //Take first 8 bytes of $key and append them to the end of $key. $key .= substr($key, 0, 8); //Pad for PKCS7 $blockSize = mcrypt_get_block_size('tripledes', 'ecb'); $len = strlen($data); $pad = $blockSize - ($len % $blockSize); $data .= str_repeat(chr($pad), $pad); //Encrypt data $encData = mcrypt_encrypt('tripledes', $key, $data, 'ecb'); return base64_encode($encData); } Here is my decrypt function: function Decrypt($data, $secret) { $text = base64_decode($data); $data = mcrypt_decrypt('tripledes', $secret, $text, 'ecb'); $block = mcrypt_get_block_size('tripledes', 'ecb'); $pad = ord($data[($len = strlen($data)) - 1]); return substr($data, 0, strlen($data) - $pad); } Right now I am using a key of test and I'm trying to encrypt 1234567. I get the base64 output from encryption I'm looking for, but when I go to decrypt I get a blank response. I'm not very well versed in encryption/decryption so any help is much appreciated!!

  • Parsing dictionary entries with regex

    - by Brandon
    I'm trying to pull data from Jim Breen's WWWJDIC. The raw data returned has a lot of information delimited in several different formats. The data pulled in the example below is from here: http://www.csse.monash.edu.au/~jwb/cgi-bin/wwwjdic.cgi?1ZUJ%E5%85%88%E7%94%9F ?? [????] /(n) (1) teacher/master/doctor/(suf) (2) with names of teachers, etc. as an honorific/(P)/ Should I use a regex?

  • Get Cell RSSI(Network Signal Strength) on Android 1.5

    - by Brandon
    Is there any way to retrieve the current cellular Signal Strength (RSSI) on Android 1.5? I know there's a way to listen for signal strength updates through the TelephonyManager, but this seems to only give a "state," not a numeric value. Is using the RSSI field on a neighboring cell fairly accurate? I'm guessing not, but I'm running out of ideas.

  • Parse Facebook API data using loop for getting fan page ID#s?

    - by Brandon Lee
    I've been learning how to parse json data returned from the facebook-api. I've figured out how to fetch fan pages from a specific profile id and want to parse them using a loop! Heres the code and example I have below: This is the data I get back from the facebook-api Array ( [0] => Array ( [page_id] => XXXXXX60828 ) [1] => Array ( [page_id] => XXXXXX0750 ) [2] => Array ( [page_id] => XXXXXX91225 ) [3] => Array ( [page_id] => XXXXXX1960343 ) [4] => Array ( [page_id] => XXXXXX60863 ) [5] => Array ( [page_id] => XXXXXX8582 ) ) I need to be able to put this data in a loop and extract the page_id#s out... still getting familiar with json and am having issues figuring this out? How can I get this in a loop using for each and strip out the page id#s?

  • Best way to access database from android

    - by Brandon Delany
    I am working on a Android app and I have a dilemma. I have a list of Objects. I have to update each of these objects with a database. I have 2 methods: Method 1: I can loop through the Objects. For each object I can connect to the server, update it, and then move on to the next Object, and so forth. Method 2: I can store the Objects in a list, send the whole list to the server, update it on the server side, then return a list of updated objects. My questions are: Which method is faster? Which method is easier on the phone's battery? By the way, Method 1 is easier for me to code :). Thank you.

  • How can I reuse .NET resources in multiple executables?

    - by Brandon
    I have an existing application that I'm supposed to take and create a "mini" version of. Both are localized apps and we would like to reuse the resources in the main application as is. So, here's the basic structure of my apps: MainApplication.csproj /Properties/Resources.resx /MainUserControl.xaml (uses strings in Properties/Resources.resx) /MainUserControl.xaml.cs MiniApplication.csproj link to MainApplication/Properties/Resources.resx link to MainApplication/MainUserControl.xaml link to MainApplication/MainUserControl.xaml.cs MiniApplication.xaml (tries to use MainUserControl from MainApplication link) So, in summary, I've added the needed resources and user control from the main application as links in the mini application. However, when I run the mini application, I get the following exception. I'm guessing it's having trouble with the different namespaces, but how do I fix? Could not find any resources appropriate for the specified culture or the neutral culture. Make sure \"MainApplication.Properties.Resources.resources\" was correctly embedded or linked into assembly \"MiniApplication\" at compile time, or that all the satellite assemblies required are loadable and fully signed. FYI, I know I could put the user control in a user control library but the problem is that the mini application needs to have a small footprint. So, we only want to include what we need.

  • Programmatically determine DPI via the browser?

    - by Brandon Pelfrey
    Hi all. I would like to programmaticaly determine the DPI of a user's display in order to show a web page at a precise number of units (centimeters/inches). I know it a weird request: it's for a visualization research project and it's kind of a control. We currently do it by having the user place a credit card to the screen and match a resizable div (via Mootools) to the real credit card, and voila we can get the DPI and display the page correctly. Can anyone think of a programmatic way to do this?

  • What is it that automatically checks config changes (such as those in /etc) into git?

    - by Brandon
    I remember reading on the ubuntu forums some time ago about a program to automatically check configuration changes into version control for you. It was (of course) not Ubuntu-specific. I'm pretty sure it used git, though it may have been svn, or perhaps even able to work with multiple different VCSs. My Googling has turned up nothing, and I'd rather not roll my own script if someone has already done this well. Of course I could just manually check things in, but there are reasons I'd like it done automatically. (I'm actually planning to use this for my LastSession.plist file for Safari, so when the #@$%^*&! thing crashes, and I don't restore everything, and then Leopard crashes, the fact that it has such lousy session management won't mean I lose the dozens of windows with dozens of tabs I had open.)

  • R: Creating Custom Shapes with ggplot

    - by Brandon Bertelsen
    Full Disclosure: This was also posted to the ggplot2 mailing list. (I'll update if I receive a response) I'm a bit lost on this one, I've tried messing around with geom_polygon but successive attempts seem worse than the previous. The image that I'm trying to recreate is this, the colours are unimportant, but the positions are: In addition to creating this, I also need to be able to label each element with text. At this point, I'm not expecting a solution (although that would be ideal) but pointers or similar examples would be immensely helpful. One option that I played with was hacking scale_shape and using 1,1 as coords. But was stuck with being able to add labels. The reason I'm doing this with ggplot, is because I'm generating scorecards on a company by company basis. This is only one plot in a 4 x 10 grid of other plots (using pushViewport) Note: The top tier of the pyramid could also be a rectangle of similar size.

  • PowerShell Script to Find and Replace for all Files with a Specific Extension

    - by Brandon
    I have several configuration files on Windows Server 2008 nested like such: C:\Projects\Project_1\project1.config C:\Projects\Project_2\project2.config In my configuration I need to do a string replace like such: <add key="Environment" value="Dev"/> will become: <add key="Environment" value="Demo"/> I thought about using batch scripting, but there was no good way to do this, and I heard that with PowerShell scripting you can easily perform this. I have found examples of find/replace, but I was hoping for a way that would traverse all folders within my C:\Projects directory and find any files that end with the '.config' extension. When it finds one, I want it to replace my string values. Any good resources to find out how to do this or any PowerShell gurus that can offer some insight?

  • is there a way to switch bash or zsh from emacs mode to vi mode with a keystroke

    - by Brandon
    I'd like to be able to switch temporarily from emacs mode to vi mode, since vi mode is sometimes better, but I'm usually half-way through typing something before I realize I want I don't want to switch permanently to vi mode, because I normally prefer emacs mode on the command line, mostly because it's what I'm used to, and over the years many of the keystrokes have become second nature. (As an editor I generally use emacs in viper mode, so that I can use both vi and emacs keystrokes, since I found myself accidentally using them in vi all the time, and screwing things up, and because in some cases I find vi keystrokes more memorable and handy, and in other cases emacs.)

  • How to implement a good system for login/out into a webapp

    - by Brandon Wang
    I am one of the developers at PassPad, a secure password generator and username storage system. We're still working on it, but I have a few questions on the best way to implement a secure login/out system. Right now, what we plan on doing is to have the login system save a cookie with the username and a session key, and that's all that serves as authentication. The server verifies the two to match. Upon login/out a new key is created. This is a security-related webapp and while we don't actually store any information that might make the user queasy, because it is security-oriented it makes it a necessity for us to at least appear secure in a way that the user would be happy with. Is there a better way to implement a login/out system in PHP? Preferably it won't take too much coding time or server resources. Is there anything else I need to implement, like brute-force protection, etc? How would I go about that?

  • Second Thread Holding Up Entire Program in C# Windows Form Application

    - by Brandon
    In my windows form application, I'm trying to test the user's ability to access a remote machine's shared folder. The way I'm doing this (and I'm sure that there are better ways...but I don't know of them) is to check for the existence of a specific directory on the remote machine (I'm doing this because of firewall/other security restrictions that I'm confronted with in my organization). If the user has rights to access the shared folder, then it returns in no time at all, but if they don't, it hangs forever. To solve this, I threw the check into another thread and wait only 1000 milliseconds before determining that the share can't be hit by the user. However, when I do this, it still hangs as if it was never run in the same thread. What is making it hang and how do I fix it? I would think that the fact that it is in a separate thread would allow me to just let the thread finish on it's own in the background. Here is my code: bool canHitInstallPath = false; Thread thread = new Thread(new ThreadStart(() => { canHitInstallPath = Directory.Exists(compInfo.InstallPath); })); thread.Start(); thread.Join(1000); if (canHitInstallPath == false) { throw new Exception("Cannot hit folder: " + compInfo.InstallPath); }

  • SQL Server 2008 - Script Data as Insert Statements from SSIS Package

    - by Brandon King
    SQL Server 2008 provides the ability to script data as Insert statements using the Generate Scripts option in Management Studio. Is it possible to access the same functionality from within a SSIS package? Here's what I'm trying to accomplish... I have a scheduled job that nightly scripts out all the schema and data for a SQL Server 2008 database and then uses the script to create a "mirror copy" SQLCE 3.5 database. I've been using Narayana Vyas Kondreddi's sp_generate_inserts stored procedure to accomplish this, but it has problems with some datatypes and greater-than-4K columns (holdovers from SQL Server 2000 days). The Script Data function looks like it could solve my problems, if only I could automate it. Any suggestions?

  • Advanced MySQL Search Help

    - by Brandon
    I've been trying to come up with something for a while now to no avail. My MySQL knowledge is rudimentary at best so I could use some guidance on what I should use for the following: I have 2 tables ('bible' and 'books') that I need to search from. Right now I am just searching 'bible' with the following query: SELECT * FROM bible WHERE text LIKE '%" . $query . "%' ORDER BY likes DESC LIMIT $start, 10 Now, I need to add another part that searches for some pretty advanced stuff. Here is what I want to do in pseudocode which I am aware doesn't work: SELECT * FROM bible WHERE books.book+' '+bible.chapter+':'+bible.verse = '$query' $query would equal something like Genesis 1:2, Genesis coming from books.book, 1 coming from bible.chapter and 2 coming from bible.verse Any help/guidance on this is much appreciated =)

  • Are concurrency issues possible when using the WCF Service Behavoir attribute set to ConcurrencyMode

    - by Brandon Linton
    We have a WCF service that makes a good deal of transactional NHibernate calls. Occasionally we were seeing SQL timeouts, even though the calls were updating different rows and the tables were set to row level locking. After digging into the logs, it looks like different threads were entering the same point in the code (our transaction using block), and an update was hanging on commit. It didn't make sense, though, because we believed that the following service class attribute was forcing a unique execution thread per service call: [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerCall)] We recently changed the concurrency mode to ConcurrencyMode.Single and haven't yet run into any issues, but the bug was very difficult to reproduce (if anyone has any thoughts on flushing a bug like that out, let me know!). Anyway, that all brings me to my question: shouldn't an InstanceContextMode of PerCall enforce thread-safety within the service, even if the ConcurrencyMode is set to multiple? How would it be possible for two calls to be serviced by the same service instance? Thanks!

  • Wunderground and UTC Offset

    - by Brandon
    I am consuming the international weather forecasts via Wunderground's XML API: http://wiki.wunderground.com/index.php/API_-_XML Looking at an output for Kabul, Afghanistan for instance: http://api.wunderground.com/auto/wui/geo/ForecastXML/index.xml?query=OAKB I notice that there is no UTC offset. The closest that I can see is this: <tz_short>AFT</tz_short> Which identifies the current TimeZone is AFT. The problem I see is that there is no universally accepted time zone abbreviations, so I cannot take these abbreviations and look up and offset from C#'s TimeZoneInfo objects. Is there a listing of Wunderground's Time Zones abbreviations/names/offsets so I can map their Time Zones to the TimeZoneInfo objects, or is there a better way to get this information? I will need to use the TimeZoneInfo so I can calculate daylight savings time for different locations internationally.

    How do I get the current compass reading in android 2.1? I know that I can initiate a listener and receive updates but I do not need constant updates I only need it to get the compass orientation when the user clicks a button. Also what is the most accurate way to get the compass orientation? Lastly, how do I send fake data to the android console. I know that you're supposed to use the terminal and send it commands but what are the commands I can't seem to find it on the Android website. Thank you

  • Lucene.NET - Find documents that do not contain a specified field

    - by Brandon
    Let's say I have 2 instance of a class called 'Animal'. Animal has 3 fields: Name, Age, and Type The name field is nullable, so before I insert an instance of Animal as a Lucene indexed document, I check if Animal.Name == null, and if it does, I do not insert it as a field in my document. If I were to retrieve all animals, I would see that the Name field does not exist and I can set its value to null. However, there may be situations where I want to say "Get me all animals that do not have a name specified yet." In this situation I want to retrieve all Lucene.NET documents from my animal index that do not contain the Name field. Is there an easy way to do this with Lucene.NET? I want to stay away from having to perform some sort of hack to check if my name field has a value of 'null'.
