• Why can't I get a TRUE return in this prepared statement?

  - by Cortopasta

  I can't seem to get this to do anything but return false. My best guess is that the prepared statement isn't executing, but I have no idea why. private function check_credentials($plain_username, $md5_password) { global $dbcon; $ac = new ac(); $ac->dbconnect(); $userid = $dbcon->prepare('SELECT id FROM users WHERE username = :username AND password = :password LIMIT 1'); $userid->bindParam(':username', $plain_username); $userid->bindParam(':password', $md5_password); $userid->execute(); $id = $userid->fetch(); Return $id; } *EDIT:*I've even tried hard coding the username and password into the function itself to try and isolate the problem like this: private function check_credentials($plain_username, $md5_password) { global $dbcon; $plain_username = "jim"; $md5_username = "waffles"; $ac = new ac(); $ac->dbconnect(); $userid = $dbcon->prepare('SELECT id FROM users WHERE username = :username AND password = :password LIMIT 1'); $userid->bindParam(':username', $plain_username); $userid->bindParam(':password', $md5_password); $userid->execute(); print_r($dbcon->errorInfo()); $id = $userid->fetch(); Return $id; } Still nothing :-/

• Can I create template-based library objects in Dreamweaver CS5?

  - by Danjah

  At work we need two 'streams' of template. The first are general layout templates, like the ones already available in the MX through CS5 packages (except we'd have our own customised ones). The second are more granular objects, some of which are functional. In both cases, I don't want Jimmy to be able to wreak havoc inside anything other than the 'editable regions' which make up the templates. Now this is fine if I stick with the first scenario (layout templates) where there's simply a big chunk of editable region for good ole Jim to sprawl into, think of this as the 'body content' area. But I really do need these granular library (or snippet) objects to work in the same way. Unfortunately with my attempts so far they don't work as I'd have thought - perhaps for good reason? When I create a blank template and throw in my chunk of HTML (unobstrusive JS and external CSS use selectors in this HTML to provide style and function) and save it as a new library item or snippet, all looks well. Then I create a new document based on a layout template and save it as a plain html file (still all good so far). Next I drop in my custom library item... still all good... but then I go to save the document and it only allows me to save it as a new template! I expected it would just allow me to save it as HTML and have it simply respect the defined editable regions, as happens in the containing page 'body content' editable region. Apologies if that got specific and technical quite quickly, but it is quite particular. If you want some example files lemme know and I'll zip some up. Many thanks :) p.s It is not a requirement that library objects must somehow inject their dependency files into the newly created page - I already know what they'll be. Also, I know I must 'detatch from original' once I drop a library item into a document which then allows customisation of the library object.

• Why did this work with Visual C++, but not with gcc?

  - by Carlos Nunez

  I've been working on a senior project for the last several months now, and a major sticking point in our team's development process has been dealing wtih rifts between Visual-C++ and gcc. (Yes, I know we all should have had the same development environment.) Things are about finished up at this point, but I ran into a moderate bug just today that had me wondering whether Visual-C++ is easier on newbies (like me) by design. In one of my headers, there is a function that relies on strtok to chop up a string, do some comparisons and return a string with a similar format. It works a little something like the following: int main() { string a, b, c; //Do stuff with a and b. c = get_string(a,b); } string get_string(string a, string b) { const char * a_ch, b_ch; a_ch = strtok(a.c_str(),","); b_ch = strtok(b.c_str(),","); } strtok is infamous for being great at tokenizing, but equally great at destroying the original string to be tokenized. Thus, when I compiled this with gcc and tried to do anything with a or b, I got unexpected behavior, since the separator used was completely removed in the string. Here's an example in case I'm unclear; if I set a = "Jim,Bob,Mary" and b="Grace,Soo,Hyun", they would be defined as a="JimBobMary" and b="GraceSooHyun" instead of staying the same like I wanted. However, when I compiled this under Visual C++, I got back the original strings and the program executed fine. I tried dynamically allocating memory to the strings and copying them the "standard" way, but the only way that worked was using malloc() and free(), which I hear is discouraged in C++. While I'm curious about that, the real question I have is this: Why did the program work when compiled in VC++, but not with gcc? (This is one of many conflicts that I experienced while trying to make the code cross-platform.) Thanks in advance! -Carlos Nunez

• what exactly is the danger of an uninitialized pointer in C

  - by akh2103

  I am trying get a handle on C as I work my way thru Jim Trevor's "Cyclone: A safe dialect of C" for a PL class. Trevor and his co-authors are trying to make a safe version of C, so they eliminate uninitialized pointers in their language. Googling around a bit on uninitialized pointers, it seems like un-initialized pointers point to random locations in memory. It seems like this alone makes them unsafe. If you reference an un-itilialized pointer, you jump to an unsafe part of memory. Period. But the way Trevor talks about them seems to imply that it is more complex. He cites the following code, and explains that when the function FrmGetObjectIndex dereferences f, it isn’t accessing a valid pointer, but rather an unpredictable address — whatever was on the stack when the space for f was allocated. What does Trevor mean by "whatever was on the stack when the space for f was allocated"? Are "un-initialized" pointers initialized to random locations in memory by default? Or does their "random" behavior have to do with the memory allocated for these pointers getting filled with strange values (that are then referenced) because of unexpected behavior on the stack. Form *f; switch (event->eType) { case frmOpenEvent: f = FrmGetActiveForm(); ... case ctlSelectEvent: i = FrmGetObjectIndex(f, field); ... }

• Virgin STI Help

  - by Mutuelinvestor

  I am working on a horse racing application and I'm trying to utilize STI to model a horse's connections. A horse's connections is comprised of his owner, trainer and jockey. Over time, connections can change for a variety of reasons: The horse is sold to another owner The owner switches trainers or jockey The horse is claimed by a new owner As it stands now, I have model this with the following tables: horses connections (join table) stakeholders (stakeholder has three sub classes: jockey, trainer & owner) Here are my clases and associations: class Horse < ActiveRecord::Base has_one :connection has_one :owner_stakeholder, :through => :connection has_one :jockey_stakeholder, :through => :connection has_one :trainer_stakeholder, :through => :connection end class Connection < ActiveRecord::Base belongs_to :horse belongs_to :owner_stakeholder belongs_to :jockey_stakeholder belongs_to :trainer_stakeholder end class Stakeholder < ActiveRecord::Base has_many :connections has_many :horses, :through => :connections end class Owner < Stakeholder # Owner specific code goes here. end class Jockey < Stakeholder # Jockey specific code goes here. end class Trainer < Stakeholder # Trainer specific code goes here. end One the database end, I have inserted a Type column in the connections table. Have I modeled this correctly. Is there a better/more elegant approach. Thanks in advance for you feedback. Jim

• Select * from 'many to many' SQL relationship

  - by Rampant Creative Group

  I'm still learning SQL and my brain is having a hard time with this one. Say I have 3 tables: teams players and teams_players as my link table All I want to do is run a query to get each team and the players on them. I tried this: SELECT * FROM teams INNER JOIN teams_players ON teams.id = teams_players.team_id INNER JOIN players ON teams_players.player_id = players.id But it returned a separate row for each player on each team. Is JOIN the right way to do it or should I be doing something else? ----------------------------------------- Edit Ok, so from what I'm hearing, this isn't necessarily a bad way to do it. I'll just have to group the data by team while I'm doing my loop. I have not yet tried the modified SQL statements provided, but I will today and get back to you. To answer the question about structure - I guess I wasn't thinking about the returned row structure which is part of what lead to my confusion. In this particular case, each team is limited to 4 players (or less) so I guess the structure that would be helpful to me is something like the following: teams.id, teams.name, players.id, players.name, players.id, players.name, players.id, players.name, players.id, players.name, 1 Team ABC 1 Jim 2 Bob 3 Ned 4 Roy 2 Team XYZ 2 Bob 3 Ned 5 Ralph 6 Tom

• Have to login twice. PHP sessions and login troubles with Chrome and Opera.

  - by Robert

  The problem I am encountering is that for my login form I have to login twice for the session to register properly, but only in Chrome (my version is 4.0.249.89) and Opera (my version is 10.10). Here is the stripped down code that I am testing on: Login Page: session_start(); $_SESSION['user_id'] = 8; $_SESSION['user_name'] = 'Jim'; session_write_close(); header('Location: http://www.my-domain-name.com/'); exit(); Home Page: session_start(); if ( isset($_SESSION['user_id']) ) { echo "You are logged in!"; } else { echo "You are NOT logged in!"; } Logout Page: session_start(); session_unset(); session_destroy(); header('Location: http://www.my-domain-name.com/'); exit(); Currently, under a fresh load with no cookies, if I go to my-domain-name.com/login/ it will redirect to the home page and say "You are NOT logged in!" but if I go there again it will say "You are logged in!". Any ideas? Thanks for your help.

• WCF throttling and emptying the listenBacklog quickly

  - by user1161625

  I'm sort of a WCF newbie (inheriting tasks from someone) and I'm trying to better throttle my application. We have a service that sends print jobs to the Windows print queue and it seems that rather than dumping all of the jobs into the queue it holds on to them in the listenBacklog and slowly releases them to the Windows print queue. Here is my throttling behavior: <behavior name="throttling"> <serviceThrottling maxConcurrentCalls="144" maxConcurrentSessions="1168" /> <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true"/> </behavior> I'm using a custom binding for this service also which is here: <customBinding> <binding name="oneWayPrintBinding" receiveTimeout="00:30:00"> <reliableSession maxPendingChannels="16" inactivityTimeout="01:30:00" /> <binaryMessageEncoding> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" /> </binaryMessageEncoding> <tcpTransport maxReceivedMessageSize="67108864" listenBacklog="1024" /> </binding> </customBinding> Any recommendations would be very helpful. Thank you! -Jim

• Populate tableView with more than one array

  - by Ewoods

  The short version: Is there a way to populate one specific row in a tableView with one value from one array, then populate another row in that same tableView with one value from a different array? For example, cell 1 would have the first value from Array A, cell 2 would have the first value from Array B, cell 3 would have the first value from Array C, etc. The long version: I hope this isn't too confusing. I've got an array of names, and then three more arrays with actions associated with those people. For example, the names array has Jim, Bob, and Sue, and then there's an array for eating, reading, and sleeping that records every time each person does one of these things (all of these arrays are populated from a MySQL database). The names array is used to populate a root tableView. Tapping on one of the names brings up a detail view controller that has another tableView that only has three rows. This part is all working fine. What I want to happen is when I tap on a name, it moves to the detail view and the three cells would then show the last event for that person for each of the three activities. Tapping on one of those three events then moves to a new view controller with a tableView that shows every event for that category. For example, if I tapped on Bob, the second page would show the last time Bob ate, read, and slept. Tapping on the first row would bring up a table that showed every time Bob has eaten. So far I've only been able to populate the second tableView with all of the rows from one of the arrays. I need it the other way around (one row from all of the arrays).

• Delivering activity feed items in a moderately scalable way

  - by sotangochips

  The application I'm working on has an activity feed where each user can see their friends' activity (much like Facebook). I'm looking for a moderately scalable way to show a given users' activity stream on the fly. I say 'moderately' because I'm looking to do this with just a database (Postgresql) and maybe memcached. For instance, I want this solution to scale to 200k users each with 100 friends. Currently, there is a master activity table that stores the rendered html for the given activity (Jim added a friend, George installed an application, etc.). This master activity table keeps the source user, the html, and a timestamp. Then, there's a separate ('join') table that simply keeps a pointer to the person who should see this activity in their friend feed, and a pointer to the object in the main activity table. So, if I have 100 friends, and I do 3 activities, then the join table will then grow to 300 items. Clearly this table will grow very quickly. It has the nice property, though, that fetching activity to show to a user takes a single (relatively) inexpensive query. The other option is to just keep the main activity table and query it by saying something like: select * from activity where source_user in (1, 2, 44, 2423, ... my friend list) This has the disadvantage that you're querying for users who may never be active, and as your friend list grows, this query can get slower and slower. I see the pros and the cons of both sides, but I'm wondering if some SO folks might help me weigh the options and suggest one way or they other. I'm also open to other solutions, though I'd like to keep it simple and not install something like CouchDB, etc. Many thanks!

• Druapl & Regular PHP Integration

  - by user333128

  I'm building a new website which has one core application and many content pages. Content pages are mostly dynamic and I require a way to manage this dynamic content on a regular basis. The core application's main functionality is a 3 step process or reading user data (input page), reading data from MySQL (product page) and submitting an application to an email address (application page). Ideally I would like to build the core application in regular PHP and leverage Drupal for its content management capabilities. Can Drupal and regular PHP be integrated as I suggest easily? My feeling is that coding the core application as a Drupal module(s) will add layers of complexity that could be difficult to code from the outset and maintain later on as the system matures - so I would really like to just use regular PHP. Let me explain where dynamic content (managed by the CMS) intersects with the core application: Dynamic content such as FAQ data is used both on the 'normal' help pages and also within a mini-feed displayed within core application pages down a right hand side column. In this column, 3 random questions are pulled from the database and displayed as a feed. When users click on FAQ question they are not taken away from the core application product page but are instead shown data in a pop-up window displaying the question and answer. In addition, users can browse other questions and answers through a simple navigation menu within this popup. There are 3 such like feeds as I describe above that I require on the core application product page. So, what is the ideal solution here in terms of 'keeping things simple' for both the management of dynamic content and the ease of coding the core application? Can 'regular PHP' and Drupal co-exist 'peacefully'? If so, how is this technically possible? Because there is some content managed by Drupal contained within core application pages, can the core application still be coded in regular PHP? Any advice / suggestions? Thank you! Jim.

• jquery accessing dynamic class selectors

  - by dinotom

  Given the following html rendering; <fieldset id="fld_Rye"> <legend>7 Main St.</legend> <div> <table> <tr> <th class="wideCol"><b><i>Service Description</i></b></th> <th class="wideCol"><b><i>Service Name</i></b></th> <th class="normalPlusWidth"><b><i>Contact Name</i></b></th> </tr> <ItemTemplate> <tr class=""> <td class="servDesc">&nbsp;<b>Plumbing Services</b></td> <td class="servName">&nbsp;<b>Flynnsters's Plumbing</b></td> <td class="servContact">&nbsp;<b>Jim Flynnster</b></td> </tr> </ItemTemplate> I am trying to access all the td's with a class of servDesc, get their width into an array and get the max width from that array to reset the css width of that class using jquery on page load. I cant seem to get the right selector for those tags, and I've tried at least 50 variations. My latest try; var maxTdWidth; var servDescCols = []; $("#fld_Rye td#servDesc").each(function () { alert("found one"); servDescCols.push(this.width()); }); maxTdWidth = Math.max.apply(Math, servDescCols);

• Can a lambda can be used to change a List's values in-place ( without creating a new list)?

  - by Saint Hill

  I am trying to determine the correct way of transforming all the values in a List using the new lambdas feature in the upcoming release of Java 8 without creating a **new** List. This pertains to times when a List is passed in by a caller and needs to have a function applied to change all the contents to a new value. For example, the way Collections.sort(list) changes a list in-place. What is the easiest way given this transforming function and this starting list: String function(String s){ return [some change made to value of s]; } List<String> list = Arrays.asList("Bob", "Steve", "Jim", "Arbby"); The usual way of applying a change to all the values in-place was this: for (int i = 0; i < list.size(); i++) { list.set(i, function( list.get(i) ); } Does lambdas and Java 8 offer: an easier and more expressive way? a way to do this without setting up all the scaffolding of the for(..) loop?

• Testing for optional node - Delphi XE

  - by Seti Net

  What is the proper way to test for the existance of an optional node? A snipped of my XML is: <Antenna > <Mount Model="text" Manufacture="text"> <BirdBathMount/> </Mount> </Antenna> But it could also be: <Antenna > <Mount Model="text" Manufacture="text"> <AzEl/> </Mount> </Antenna> The child of Antenna could either be BirdBath or AzEl but not both... In Delphi XE I have tried: if (MountNode.ChildNodes.Nodes['AzEl'] <> unassigned then //Does not work if (MountNode.ChildNodes['BirdBathMount'].NodeValue <> null) then // Does not work if (MountNode.BirdBathMount.NodeValue <> null) then // Does not work I use XMLSpy to create the schema and the example XML and they parse correctly. I use Delphi XE to create the bindings and it works on most other combinations fine. This must have a simple answer that I have just overlooked - but what? Thanks...... Jim

• Programmatically use a server as the Build Server for multiple Project Collections

  Important: With this post you create an unsupported scenario by Microsoft. It will break your support for this server with Microsoft. So handle with care. I am the administrator an a TFS environment with a lot of Project Collections. In the supported configuration of Microsoft 2010 you need one Build Controller per Project Collection, and it is not supported to have multiple Build Controllers installed. Jim Lamb created a post how you can modify your system to change this behaviour. But since I have so many Project Collections, I automated this with the API of TFS. When you install a new build server via the UI, you do the following steps Register the build service (with this you hook the windows server into the build server environment) Add a new build controller Add a new build agent So in pseudo code, the code would look like foreach (projectCollection in GetAllProjectCollections) {       CreateNewWindowsService();       RegisterService();       AddNewController();       AddNewAgent(); } The following code fragements show you the most important parts of the method implementations. Attached is the full project. CreateNewWindowsService We create a new windows service with the SC command via the Diagnostics.Process class:             var pi = new ProcessStartInfo("sc.exe")                         {                             Arguments =                                 string.Format(                                     "create \"{0}\" start= auto binpath= \"C:\\Program Files\\Microsoft Team Foundation Server 2010\\Tools\\TfsBuildServiceHost.exe              /NamedInstance:{0}\" DisplayName= \"Visual Studio Team Foundation Build Service Host ({1})\"",                                     serviceHostName, tpcName)                         };            Process.Start(pi);             pi.Arguments = string.Format("failure {0} reset= 86400 actions= restart/60000", serviceHostName);            Process.Start(pi); RegisterService The trick in this method is that we set the NamedInstance static property. This property is Internal, so we need to set it through reflection. To get information on these you need nice Microsoft friends and the .Net reflector .             // Indicate which build service host instance we are using            typeof(BuildServiceHostUtilities).Assembly.GetType("Microsoft.TeamFoundation.Build.Config.BuildServiceHostProcess").InvokeMember("NamedInstance",              System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.SetProperty | System.Reflection.BindingFlags.Static, null, null, new object[] { serviceName });             // Create the build service host            serviceHost = buildServer.CreateBuildServiceHost(serviceName, endPoint);            serviceHost.Save();             // Register the build service host            BuildServiceHostUtilities.Register(serviceHost, user, password); AddNewController and AddNewAgent Once you have the BuildServerHost, the rest is pretty straightforward. There are methods on the BuildServerHost to modify the controllers and the agents                 controller = serviceHost.CreateBuildController(controllerName);                 agent = controller.ServiceHost.CreateBuildAgent(agentName, buildDirectory, controller);                controller.AddBuildAgent(agent); You have now seen the highlights of the application.

• Off The Beaten Path—Three Things Growing Midsize Companies are Thankful For

  - by Christine Randle

  By: Jim Lein, Senior Director, Oracle Accelerate Last Sunday I went on a walkabout.  That’s when I just step out the door of my Colorado home and hike through the mountains for hours with no predetermined destination. I favor “social trails”, the unmapped routes pioneered by both animal and human explorers.  These tracks  are usually more challenging than established, marked routes and you can’t be 100% sure of where you’re going to end up. But I’ve found the rewards to be much greater. For awhile, I pondered on how—depending upon your perspective—the current economic situation worldwide could be viewed as either a classic “the glass is half empty” or a “the glass is half full” scenario. Midsize companies buy Oracle to grow and so I’m continually amazed and fascinated by the success stories our customers relate to me.  Oracle’s successful midsize companies are growing via innovation, agility, and opportunity. For them, the glass isn’t half full—it’s overflowing. Growing Midsize Companies are Thankful for: Innovation The sun angling through the pine trees reminded me of a conversation with a European customer a year ago May.  You might not recognize the name but, chances are, your local evening weather report relies on this company’s weather observation, monitoring and measurement products.  For decades, the company was recognized in its industry for product innovation, but its recent rapid growth comes from tailoring end to end product and service solutions based on the needs of distinctly different customer groups across industrial, public sector, and defense sectors.  Hours after that phone call I was walking my dog in a local park and came upon a small white plastic box sprouting short antennas and dangling by a nylon cord from a tree branch.  I cut it down. The name of that customer’s company was stamped on the housing. “It’s a radiosonde from a high altitude weather balloon,” he told me the next day. “Keep it as a souvenir.”  It sits on my fireplace mantle and elicits many questions from guests. Growing Midsize Companies are Thankful for: Agility In July, I had another interesting discussion with the CFO of an Asia-Pacific company which owns and operates a large portfolio of leisure assets. They are best known for their epic outdoor theme parks. However, their primary growth today is coming from a chain of indoor amusement centers in the USA where billiards, bowling, and laser tag take the place of roller coasters, kiddy rides, and wave pools. With mountains and rivers right out my front door, I’m not much for theme parks, but I’ll take a spirited game of laser tag any day.  This company has grown dramatically since first implementing Oracle ERP more than a decade ago. Their profitable expansion into a completely foreign market is derived from the ability to replicate proven and efficient best business practices across diverse operating environments.  They recently went live on Oracle’s Fusion HCM and Taleo. Their CFO explained to me how, with thousands of employees in three countries, Fusion HCM and Taleo would enable them to remain incredibly agile by acting on trends linking individual employee performance to their management, establishing and maintaining those best practices. Growing Midsize Companies are Thankful for: Opportunity I have three GPS apps on my iPhone. I use them mainly to keep track of my stats—distance, time, and vertical gain. However, every once in awhile I need to find the most efficient route back home before dark from my current location (notice I didn’t use the word “lost”). In August I listened in on an interview with the CFO of another European company that designs and delivers telematics solutions—the integrated use of telecommunications and informatics—for managing the mobile workforce. These solutions enable customers to achieve evolutionary step-changes in their performance and service delivery. Forgive the overused metaphor, but this is route optimization on steroids.  The company’s executive team saw an opportunity in this emerging market and went “all in”. Consequently, they are being rewarded with tremendous growth results and market domination by providing the ability for their clients to collect and analyze performance information related to fuel consumption, service workforce safety, and asset productivity. This Thanksgiving, I’m thankful for health, family, friends, and a career with an innovative company that helps companies leverage top tier software to drive and manage growth. And I’m thankful to have learned the lesson that good things happen when you get off the beaten path—both when hiking and when forging new routes through a complex world economy. Halfway through my walkabout on Sunday, after scrambling up a long stretch of scree-covered hill, I crested a ridge with an obstructed view of 14,265 ft Mt Evans just a few miles to the west.  There, nowhere near a house or a trail, someone had placed a wooden lounge chair. Its wood was worn and faded but it was sturdy. I had lunch and a cold drink in my pack. Opportunity knocked and I seized it. Happy Thanksgiving.

• 5 Things I Learned About the IT Labor Shortage

It’s time to wrap up the series that I started back in April, “The Growing IT Labor Shortage: Are You Feeling It?” Even in a time of relatively high unemployment, labor shortages exist depending on many factors, including location, industry, IT requirements, and company size. According to Manpower Groups 2013 Talent Shortage Survey, 35% of hiring managers globally are having difficulty filling jobs. Their top three challenges in filling jobs are: 1. lack of technical competencies (hard skills) 2. Lack of available applicants 3. Lack of experience The same report listed Technicians as the most difficult position to fill in the United States For most companies, Human Capital and Talent Management have never been more strategic and they are striving for ways streamline processes, reduce turnover, and lower costs (see this Oracle whitepaper, “ Simplify Workforce Management and Increase Global Agility”). Everyone I spoke to—partner, customer, and Oracle experts—agreed that it can be extremely challenging to hire and retain IT talent in today’s labor market. And they generally agreed on the causes: a. IT is so pervasive that there are myriad moving parts requiring support and expertise, b. thus, it’s hard for university graduates to step in and contribute immediately without experience and specialization, c. big IT companies generally aren’t the talent incubators that they were in the freewheeling 90’s due to bottom line pressures that require hiring talent that can hit the ground running, and d. it’s often too expensive for resource-strapped midsize companies to invest the time and money required to get graduates up to speed. Here are my top lessons learned from my conversations with the experts. 1. A Better Title Would Have Been, “The Challenges of Finding and Retaining IT Talent That Matches Your Requirements” There are more applicants than jobs but it’s getting tougher and tougher to find individuals that perfectly fit each and every role. Top performing companies are increasingly looking to hire the “almost ready”, striving to keep their existing talent more engaged, and leveraging their employee’s social and professional networks to quickly narrow down candidate searches (here’s another whitepaper, “A Strategic Approach to Talent Management”). 2. Size Matters—But So Does Location Midsize companies must strive to build cultures that compete favorably with what large enterprises can offer, especially when they aren’t within commuting distance of IT talent strongholds. They can’t always match the compensation and benefits offered by large enterprises so it's paramount to offer candidates high quality of life and opportunities to build their resumes in alignment with their long term career aspirations. 3. Get By With a Little Help From Your Friends It doesn’t always make sense to invest time and money in training an employee on a task they will not perform frequently. Or get in a bidding war for talent with skills that are rare and in high demand. Many midsize companies are finding that it makes good economic sense to contract with partners for remote support rather than trying to divvy up each and every role amongst their lean staff. Internal staff can be assigned to roles that will have the highest positive impact on achieving organizational goals. 4. It’s Actually Both “What You Know” AND “Who You Know” If I was hiring someone today I would absolutely leverage the social and professional networks of my co-workers. Period. Most research shows that hiring in this manner is less expensive and time consuming AND produces better results. There is also some evidence that suggests new hires from employees’ networks have higher job performance and retention rates. 5. I Have New Respect for Recruiters and Hiring Managers My hats off to them—it’s not easy hiring and retaining top talent with today’s challenges. Check out the infographic, “A New Day: Taking HR from Chaos to Control”, on Oracle’s Human Capital Management solutions home page. You can also explore all of Oracle’s HCM solutions from that page based on your role. You can read all the posts in this series by clicking on the links in the right sidebar. Stay tuned…we’ll continue to post thought leadership on HCM and Talent Management topics.

• Validation firing in ASP.NET MVC

  - by rkrauter

  I am lost on this MVC project I am working on. I also read Brad Wilsons article. http://bradwilson.typepad.com/blog/2010/01/input-validation-vs-model-validation-in-aspnet-mvc.html I have this: public class Employee { [Required] public int ID { get; set; } [Required] public string FirstName { get; set; } [Required] public string LastName { get; set; } } and these in a controller: public ActionResult Edit(int id) { var emp = GetEmployee(); return View(emp); } [HttpPost] public ActionResult Edit(int id, Employee empBack) { var emp = GetEmployee(); if (TryUpdateModel(emp,new string[] { "LastName"})) { Response.Write("success"); } return View(emp); } public Employee GetEmployee() { return new Employee { FirstName = "Tom", LastName = "Jim", ID = 3 }; } and my view has the following: <% using (Html.BeginForm()) {%> <%= Html.ValidationSummary() %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.FirstName) %> </div> <div class="editor-field"> <%= Html.DisplayFor(model => model.FirstName) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.LastName) %> </div> <div class="editor-field"> <%= Html.TextBoxOrLabelFor(model => model.LastName, true)%> <%= Html.ValidationMessageFor(model => model.LastName) %> </div> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> Note that the only field editable is the LastName. When I postback, I get back the original employee and try to update it with only the LastName property. But but I see on the page is the following error: •The FirstName field is required. This from what I understand, is because the TryUpdateModel failed. But why? I told it to update only the LastName property. I am using MVC2 RTM Thanks in advance.

• Looking for efficient scaling patterns for Silverlight application with distributed text-file data s

  - by Edward Tanguay

  I'm designing a Silverlight software solution for students and teachers to record flashcards, e.g. words and phrases that students find while reading and errors that teachers notice while teaching. Requirements are: each person publishes his own flashcards in a file on a web server, e.g. http://:www.mywebserver.com/flashcards.txt other people subscribe to that person's flashcards by using a Silverlight flashcard reader that I have developed and entering the URLs of flashcard files they want to subscribe to, URLs and imported flashcards being saved in IsolatedStorage the flashcards.txt file has the following simple format: title, then blocks of question/answers: Jim Smith's flashcards from English class 53-222, winter semester 2009 ==fla Das kann nicht sein. That can't be. ==fla Es sei denn, er kommt nicht. Unless he doesn't come. The user then makes public the URL to his flashcard file and other readers begin reading in his flashcards. In order to lower the bar for non-technical users to contribute, it will even be possible for them to save this text in a Google Document, which they publish and distribute the URL. The flashcard readers will then recognize it is a google document and perform the necessary screen scraping to get at the raw text. I have two technical questions about this approach: What is a best way to plan now for scalability issues: e.g. if your reader is subscribed to 10 flashcard files that are each 200K, it will have to download 2MB of text just to find out if any new flashcards are available. Or can I somehow accurately and consistently get at the last update date/time of text files on servers and published google docs? Each reader will have the ability to allow the person to test himself on imported flashcards and add meta information to them, e.g. categorize them, edit them, etc. This information will be stored in IsolatedStorage along with the important flashcards themselves. What is a good pattern to allow these readers to share and synchronize this meta data, e.g. so when you are looking at a flashcard you can see that 5 other people have made corrections to it. The best solution I can think of now is that the Silverlight readers will have to republish their data to a central database, but then there is the problem of uniquely identifying each flashcard, the best approach seems to be URL + position-in-file, or even better URL + original text of both question and answer fields, but both of these have their obvious drawbacks. The main requirement is that the bar for participation is kept as low as possible, i.e. type text in a google document, publish it, distribute the URL, and you're publishing within the flashcard community. So I want to come up with the most efficient technical solutions in order to compensate for the lack of database, lack of unique ids, etc. For those who have designed or developed similar non-traditional, distributed database projects like this, what advice, experience or best-practice tips you can share on the above two points?

• Event Listener in Google Charts API

  - by DeanGrobler

  I'm busy using Google Charts in one of my projects to display data in a table. Everything is working great. Except that I need to see what line a user selected once they click a button. This would obviously be done with Javascript, but I've been struggling for days now to no avail. Below I've pasted code for a simple example of the table, and the Javascript function that I want to use (that doesn't work). <html> <head> <script type='text/javascript' src='https://www.google.com/jsapi'></script> <script type='text/javascript'> google.load('visualization', '1', {packages:['table']}); google.setOnLoadCallback(drawTable); var table = ""; function drawTable() { var data = new google.visualization.DataTable(); data.addColumn('string', 'Name'); data.addColumn('number', 'Salary'); data.addColumn('boolean', 'Full Time Employee'); data.addRows(4); data.setCell(0, 0, 'Mike'); data.setCell(0, 1, 10000, '$10,000'); data.setCell(0, 2, true); data.setCell(1, 0, 'Jim'); data.setCell(1, 1, 8000, '$8,000'); data.setCell(1, 2, false); data.setCell(2, 0, 'Alice'); data.setCell(2, 1, 12500, '$12,500'); data.setCell(2, 2, true); data.setCell(3, 0, 'Bob'); data.setCell(3, 1, 7000, '$7,000'); data.setCell(3, 2, true); table = new google.visualization.Table(document.getElementById('table_div')); table.draw(data, {showRowNumber: true}); } function selectionHandler() { selectedData = table.getSelection(); row = selectedData[0].row; item = table.getValue(row,0); alert("You selected :" + item); } </script> </head> <body> <div id='table_div'></div> <input type="button" value="Select" onClick="selectionHandler()"> </body> </html> Thanks in advance for anyone taking the time to look at this. I've honestly tried my best with this, hope someone out there can help me out a bit.

  According to how Silverlight TwoWay binding works, when I change the data in the FirstName field, it should change the value in CheckFirstName field. Why is this not the case? ANSWER: Thank you Jeff, that was it, for others: here is the full solution with downloadable code. XAML: <StackPanel> <Grid x:Name="GridCustomerDetails"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="300"/> </Grid.ColumnDefinitions> <TextBlock VerticalAlignment="Center" Margin="10" Grid.Row="0" Grid.Column="0">First Name:</TextBlock> <TextBox Margin="10" Grid.Row="0" Grid.Column="1" Text="{Binding FirstName, Mode=TwoWay}"/> <TextBlock VerticalAlignment="Center" Margin="10" Grid.Row="1" Grid.Column="0">Last Name:</TextBlock> <TextBox Margin="10" Grid.Row="1" Grid.Column="1" Text="{Binding LastName}"/> <TextBlock VerticalAlignment="Center" Margin="10" Grid.Row="2" Grid.Column="0">Address:</TextBlock> <TextBox Margin="10" Grid.Row="2" Grid.Column="1" Text="{Binding Address}"/> </Grid> <Border Background="Tan" Margin="10"> <TextBlock x:Name="CheckFirstName"/> </Border> </StackPanel> Code behind: public Page() { InitializeComponent(); Customer customer = new Customer(); customer.FirstName = "Jim"; customer.LastName = "Taylor"; customer.Address = "72384 South Northern Blvd."; GridCustomerDetails.DataContext = customer; Customer customerOutput = (Customer)GridCustomerDetails.DataContext; CheckFirstName.Text = customer.FirstName; }

• Sanitizing DB inputs with XSLT

  - by azathoth

  Hello I've been looking for a method to strip my XML content of apostrophes (') like: <name> Jim O'Connor</name> since my DBMS is complaining of receiving those. By looking at the example described here, that is supposed to replace ' with '', I constructed the following script: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes" /> <xsl:template match="node()|@*"> <xsl:copy> <xsl:apply-templates select="node()|@*" /> </xsl:copy> </xsl:template> <xsl:template name="sqlApostrophe"> <xsl:param name="string" /> <xsl:variable name="apostrophe">'</xsl:variable> <xsl:choose> <xsl:when test="contains($string,$apostrophe)"> <xsl:value-of select="concat(substring-before($string,$apostrophe), $apostrophe,$apostrophe)" disable-output-escaping="yes" /> <xsl:call-template name="sqlApostrophe"> <xsl:with-param name="string" select="substring-after($string,$apostrophe)" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$string" disable-output-escaping="yes" /> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="node()|@*"> <xsl:apply-templates name="sqlApostrophe"/> </xsl:template> </xsl:stylesheet> However, the processor isn't accepting it. What am I missing here? Is there a better way to get rid of the apostrophes? Perhaps another approach for sanitizing DB inputs by using XSLT? Thanks for your help
