  • Can an UPS be too powerful?

    - by Andy
    Our old network admin bought the top range UPS a few months ago but never came around to setting it up and is no longer with the company. Now the old UPS broke down and needs to be replaced, but an external company that did an audit said that that UPS won't work. Now we are no hardware specialists, but the difference in specs is a higher output from 5A to 8.8A meaning a higher output. But isn't the UPS supposed to give the server the required output anyway? This 'independent' audit does sell its own hardware including UPSes so I'm not sure how much bias they have. Is there a reason why we can't replace the old broken UPS with the new more powerful one? Is there a way we can check to see if the UPS works with our server? ok, i wrote down the numbers again, the Volts and Amps are what are on the back (where you connect up the plugs which seem diffrent from on the front label.) old one APC SmartUPS 1500 220-240V -- 6.8A new one Dell UPS 1920W 250V -- 10A

  • Rails ActiveRecord friendly code from a Complex Join, Sum, and Group query

    - by Chad M
    PROBLEM Hello, I am having no luck trying to break down this SQL statement into ActiveRecord/Rails friendly code and I'd like to learn how I can avoid a find_by_sql statement in this situation. Scenario I have users that create audits when they perform an action. Each audit is of a specific audit_activity. Each audit_activity is worth a certain number of points, based on score_weight. I need to find the total scores of each user, based on their total accumulated audit_activity score_weights. Eventually I'll need to rank them which means adding a sort to this as well. My Code Here is my sql and simplified versions of the tables in question. Any thoughts? SQL with full column names (for clarity) SELECT users.id, u.email, SUM(audit_activity.score_weight) FROM users JOIN audits ON users.id = audits.user_id JOIN audit_activities ON audit_activities.id = audits.audit_activity_id GROUP BY users.id; Models: User, Audit, AuditActivity User fields: id, email class User < ActiveRecord::Base include Clearance::User has_many :audits end Audit fields: id, user_id, audit_activity_id class Audit < ActiveRecord::Base belongs_to :user belongs_to :audit_activity end AuditActivity fields: id, score_weight class AuditActivity < ActiveRecord::Base has_many :audits end Example Data Here is a set of SQL statements so you can play with similar data I'm working with and see what comes up when the concerned query is run. You should just be able to copy/paste the whole thing into a database query browser. CREATE TABLE users( id INTEGER NOT NULL, email TEXT (25), PRIMARY KEY (id) ); CREATE TABLE audits( id INTEGER NOT NULL, user_id INTEGER, audit_activity_id INTEGER, PRIMARY KEY (id) ); CREATE TABLE audit_activities( id INTEGER NOT NULL, score_weight INTEGER, PRIMARY KEY (id) ); INSERT INTO users(id, email) VALUES(1, "[email protected]"); INSERT INTO users(id, email) VALUES(2, "[email protected]"); INSERT INTO users(id, email) VALUES(3, "[email protected]"); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(1, 1, 1); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(2, 1, 2); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(3, 1, 1); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(4, 1, 3); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(5, 1, 1); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(6, 1, 4); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(7, 2, 4); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(8, 2, 4); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(9, 2, 4); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(10, 3, 3); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(11, 3, 2); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(12, 3, 2); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(13, 3, 2); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(14, 3, 3); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(15, 3, 1); INSERT INTO audits(id, user_id, audit_activity_id) VALUES(16, 3, 1); INSERT INTO audit_activities(id, score_weight) VALUES(1, 1); INSERT INTO audit_activities(id, score_weight) VALUES(2, 2); INSERT INTO audit_activities(id, score_weight) VALUES(3, 7); INSERT INTO audit_activities(id, score_weight) VALUES(4, 11); The Query Again, here is the query. SELECT u.id, u.email, SUM(aa.score_weight) FROM users u JOIN audits a ON u.id = a.user_id JOIN audit_activities aa ON aa.id = a.audit_activity_id GROUP BY u.id; Many Thanks, Chad

  • Drupal Adding Span inside A tags in Nice Menus

    - by Chris
    I am trying to add drop down menus to a drupal theme which uses text sliding door CSS rounding. The current version uses a primary links injection of the span into the a tags, which works fine. But doesn't support drop down menus. Working code: <?php print theme('links', $primary_links, array('class' => 'links primary-links')) ?> In the template with a template.php file addition: <?php // function for injecting spans inside anchors which we need for the theme's rounded corner background images function strands_guybrush_links($links, $attributes = array('class' => 'links')) { $output = ''; if (count($links) > 0) { $output = '<ul'. drupal_attributes($attributes) .'>'; $num_links = count($links); $i = 1; foreach ($links as $key => $link) { $class = $key; // Add first, last and active classes to the list of links to help out themers. if ($i == 1) { $class .= ' first'; } if ($i == $num_links) { $class .= ' last'; } if (isset($link['href']) && ($link['href'] == $_GET['q'] || ($link['href'] == '<front>' && drupal_is_front_page()))) { $class .= ' active'; } $output .= '<li'. drupal_attributes(array('class' => $class)) .'>'; if (isset($link['href'])) { $link['title'] = '<span class="link">' . check_plain($link['title']) . '</span>'; $link['html'] = TRUE; // Pass in $link as $options, they share the same keys. $output .= l($link['title'], $link['href'], $link); } else if (!empty($link['title'])) { // Some links are actually not links, but we wrap these in <span> for adding title and class attributes if (empty($link['html'])) { $link['title'] = check_plain($link['title']); } $span_attributes = ''; if (isset($link['attributes'])) { $span_attributes = drupal_attributes($link['attributes']); } $output .= '<span'. $span_attributes .'>'. $link['title'] .'</span>'; } $i++; $output .= "</li>\n"; } $output .= '</ul>'; } return $output; } ?> So I have added the [Nice Menu module][1] which works well and allows the drop down menu functions for my navigation which is now addressed from the template using: <?php print theme_nice_menu_primary_links() ?> The issue is that the a tags need to have spans inside to allow for the selected state markup. I have tried every angle I could find to edit the drupal function menu_item_link which is used by nice menus to build the links. E.g. I looked at the drupal forum for two days and no joy. The lines in the module that build the links are: function theme_nice_menu_build($menu) { $output = ''; // Find the active trail and pull out the menus ids. menu_set_active_menu_name('primary-links'); $trail = menu_get_active_trail('primary-links'); foreach ($trail as $item) { $trail_ids[] = $item['mlid']; } foreach ($menu as $menu_item) { $mlid = $menu_item['link']['mlid']; // Check to see if it is a visible menu item. if ($menu_item['link']['hidden'] == 0) { // Build class name based on menu path // e.g. to give each menu item individual style. // Strip funny symbols. $clean_path = str_replace(array('http://', '<', '>', '&', '=', '?', ':'), '', $menu_item['link']['href']); // Convert slashes to dashes. $clean_path = str_replace('/', '-', $clean_path); $class = 'menu-path-'. $clean_path; $class .= in_array($mlid, $trail_ids) ? ' active' : ''; // If it has children build a nice little tree under it. if ((!empty($menu_item['link']['has_children'])) && (!empty($menu_item['below']))) { // Keep passing children into the function 'til we get them all. $children = theme('nice_menu_build', $menu_item['below']); // Set the class to parent only of children are displayed. $class .= $children ? ' menuparent ' : ''; // Add an expanded class for items in the menu trail. $output .= '<li id="menu-'. $mlid .'" class="'. $class .'">'. theme('menu_item_link', $menu_item['link']); // Build the child UL only if children are displayed for the user. if ($children) { $output .= '<ul>'; $output .= $children; $output .= "</ul>\n"; } $output .= "</li>\n"; } else { $output .= '<li id="menu-'. $mlid .'" class="'. $class .'">'. theme('menu_item_link', $menu_item['link']) .'</li>'."\n"; } } } return $output; } As you can see the $output uses menu_item_link to parse the array into links and to added the class of active to the selected navigation link. The question is how do I add a span inside the a tags OR how do I wrap the a tags with a span that has the active class to style the sliding door links? drupal.org/project/nice_menus drupal.org/node/53233

  • Unit testing is… well, flawed.

    - by Dewald Galjaard
    Hey someone had to say it. I clearly recall my first IT job. I was appointed Systems Co-coordinator for a leading South African retailer at store level. Don’t get me wrong, there is absolutely nothing wrong with an honest day’s labor and in fact I highly recommend it, however I’m obliged to refer to the designation cautiously; in reality all I had to do was monitor in-store prices and two UNIX front line controllers. If anything went wrong – I only had to phone it in… Luckily that wasn’t all I did. My duties extended to some other interesting annual occurrence – stock take. Despite a bit more curious affair, it was still a tedious process that took weeks of preparation and several nights to complete.  Then also I remember that no matter how elaborate our planning was, the entire exercise would be rendered useless if we couldn’t get the basics right – that being the act of counting. Sounds simple right? We’ll with a store which could potentially carry over tens of thousands of different items… we’ll let’s just say I believe that’s when I first became a coffee addict. In those days the act of counting stock was a very humble process. Nothing like we have today. A staff member would be assigned a bin or shelve filled with items he or she had to sort then count. Thereafter they had to record their findings on a complementary piece of paper. Every night I would manage several teams. Each team was divided into two groups - counters and auditors. Both groups had the same task, only auditors followed shortly on the heels of the counters, recounting stock levels, making sure the original count correspond to their findings. It was a simple yet hugely responsible orchestration of people and thankfully there was one fundamental and golden rule I could always abide by to ensure things run smoothly – No-one was allowed to audit their own work. Nope, not even on nights when I didn’t have enough staff available. This meant I too at times had to get up there and get counting, or have the audit stand over until the next evening. The reason for this was obvious - late at night and with so much to do we were prone to make some mistakes, then on the recount, without a fresh set of eyes, you were likely to repeat the offence. Now years later this rule or guideline still holds true as we develop software (as far removed as software development from counting stock may be). For some reason it is a fundamental guideline we’re simply ignorant of. We write our code, we write our tests and thus commit the same horrendous offence. Yes, the procedure of writing unit tests as practiced in most development houses today – is flawed. Most if not all of the tests we write today exercise application logic – our logic. They are based on the way we believe an application or method should/may/will behave or function. As we write our tests, our unit tests mirror our best understanding of the inner workings of our application code. Unfortunately these tests will therefore also include (or be unaware of) any imperfections and errors on our part. If your logic is flawed as you write your initial code, chances are, without a fresh set of eyes, you will commit the same error second time around too. Not even experience seems to be a suitable solution. It certainly helps to have deeper insight, but is that really the answer we should be looking for? Is that really failsafe? What about code review? Code review is certainly an answer. You could have one developer coding away and another (or team) making sure the logic is sound. The practice however has its obvious drawbacks. Firstly and mainly it is resource intensive and from what I’ve seen in most development houses, given heavy deadlines, this guideline is seldom adhered to. Hardly ever do we have the resources, money or time readily available. So what other options are out there? A quest to find some solution revealed a project by Microsoft Research called PEX. PEX is a framework which creates several test scenarios for each method or class you write, automatically. Think of it as your own personal auditor. Within a few clicks the framework will auto generate several unit tests for a given class or method and save them to a single project. PEX help to audit your work. It lends a fresh set of eyes to any project you’re working on and best of all; it is cost effective and fast. Check them out at http://research.microsoft.com/en-us/projects/pex/ In upcoming posts we’ll dive deeper into how it works and how it can help you.   Certainly there are more similar frameworks out there and I would love to hear from you. Please share your experiences and insights.

  • Extended URL php

    - by web.ask
    I have a problem with the extended url here in php. I'm not even sure if it's called extended url. I was wondering if someone can help me since i'm no good with PHP. I have a php page the careers.php it shows the career listing but when I click on Learn more link it goes to http(dot)localhost/houseofpatel/jobs/4/Career-4 but it outputs an "Object not found". Does xampplite have something to do with this? or is it just the codes? I also have the breadcrumb.php in here. Please see code below: session_start(); include("Breadcrumb.php"); $trail = new Breadcrumb(); $trail->add('Careers', $_SERVER['PHP_SELF'], 1); $trail -> output(); # REMOVE SPECIAL CHARACTERS $sPattern = array('/[^a-zA-Z0-9 -]/', '/[ -]+/', '/^-|-$/'); $sReplace = array('', '-', ''); mysql_query("SET CHARACTER_SET utf8"); //$query = "SELECT * FROM careers_mst WHERE status = 1 ORDER BY dateposted DESC LIMIT 0, 4"; if(!$_GET['jobs']){ $jobsPerPage = 4; }else{ $jobsPerPage = $_GET['jobs']; } if(!$_GET['page']){ $currPage = 1; $showMoreJobs = true; }else{ $currPage = $_GET['page']; $showMoreJobs = false; } $offset = ($currPage - 1 )* $jobsPerPage; $query = "SELECT * FROM careers_mst WHERE status = 1 ORDER BY dateposted"; $process = mysql_query($query); if(@mysql_num_rows($process) > 0){ $totalRows = @mysql_num_rows($process); $query2 = "SELECT * FROM careers_mst WHERE status = 1 ORDER BY dateposted DESC LIMIT $offset, $jobsPerPage"; $process2 = mysql_query($query2); if(@mysql_num_rows($process2) > 0){ $pagNav = pageNavigator($totalRows,$jobsPerPage,$currPage,''); while($row = @mysql_fetch_array($process2)){ $id = $row[0]; $title = stripslashes($row['title']); $title1 = preg_replace($sPattern, $sReplace, $title); $description = stripslashes($row['description']); $description1 = substr($description, 0, 200); $careers_list .= ' <div class="left" style="width:340px; padding-left:10px;"> <p><span class="blue"><strong>'.$title.'</strong></span></p> '.$description1.'... <p><a href="jobs/'.$id.'/'.$title1.'" title="Learn more">[ Learn More ]</a></p> </div>'; } /*$careers_list .= ' <div class="left" style="width: 100%; margin-top:15px;"> <p><a href="more-jobs" title="More Job Opennings">MORE JOB OPENNINGS >> </a></p> <div class="divider left"></div> </div>'; */ if($showMoreJobs){ if($totalRows > $jobsPerPage){ $currPage++; } $jobNav = "<a href=careers.php?page=$currPage title='More Job Opennings'>MORE JOB OPENNINGS >> </a>"; }else{ $jobNav = "$pagNav"; } $careers_list .= "<div class='left' style='width: 100%; margin-top:15px;'> <p>$jobNav</p> <div class='divider left'></div> </div>"; } }

  • .NET Security Part 3

    - by Simon Cooper
    You write a security-related application that allows addins to be used. These addins (as dlls) can be downloaded from anywhere, and, if allowed to run full-trust, could open a security hole in your application. So you want to restrict what the addin dlls can do, using a sandboxed appdomain, as explained in my previous posts. But there needs to be an interaction between the code running in the sandbox and the code that created the sandbox, so the sandboxed code can control or react to things that happen in the controlling application. Sandboxed code needs to be able to call code outside the sandbox. Now, there are various methods of allowing cross-appdomain calls, the two main ones being .NET Remoting with MarshalByRefObject, and WCF named pipes. I’m not going to cover the details of setting up such mechanisms here, or which you should choose for your specific situation; there are plenty of blogs and tutorials covering such issues elsewhere. What I’m going to concentrate on here is the more general problem of running fully-trusted code within a sandbox, which is required in most methods of app-domain communication and control. Defining assemblies as fully-trusted In my last post, I mentioned that when you create a sandboxed appdomain, you can pass in a list of assembly strongnames that run as full-trust within the appdomain: // get the Assembly object for the assembly Assembly assemblyWithApi = ... // get the StrongName from the assembly's collection of evidence StrongName apiStrongName = assemblyWithApi.Evidence.GetHostEvidence<StrongName>(); // create the sandbox AppDomain sandbox = AppDomain.CreateDomain( "Sandbox", null, appDomainSetup, restrictedPerms, apiStrongName); Any assembly that is loaded into the sandbox with a strong name the same as one in the list of full-trust strong names is unconditionally given full-trust permissions within the sandbox, irregardless of permissions and sandbox setup. This is very powerful! You should only use this for assemblies that you trust as much as the code creating the sandbox. So now you have a class that you want the sandboxed code to call: // within assemblyWithApi public class MyApi { public static void MethodToDoThings() { ... } } // within the sandboxed dll public class UntrustedSandboxedClass { public void DodgyMethod() { ... MyApi.MethodToDoThings(); ... } } However, if you try to do this, you get quite an ugly exception: MethodAccessException: Attempt by security transparent method ‘UntrustedSandboxedClass.DodgyMethod()’ to access security critical method ‘MyApi.MethodToDoThings()’ failed. Security transparency, which I covered in my first post in the series, has entered the picture. Partially-trusted code runs at the Transparent security level, fully-trusted code runs at the Critical security level, and Transparent code cannot under any circumstances call Critical code. Security transparency and AllowPartiallyTrustedCallersAttribute So the solution is easy, right? Make MethodToDoThings SafeCritical, then the transparent code running in the sandbox can call the api: [SecuritySafeCritical] public static void MethodToDoThings() { ... } However, this doesn’t solve the problem. When you try again, exactly the same exception is thrown; MethodToDoThings is still running as Critical code. What’s going on? By default, a fully-trusted assembly always runs Critical code, irregardless of any security attributes on its types and methods. This is because it may not have been designed in a secure way when called from transparent code – as we’ll see in the next post, it is easy to open a security hole despite all the security protections .NET 4 offers. When exposing an assembly to be called from partially-trusted code, the entire assembly needs a security audit to decide what should be transparent, safe critical, or critical, and close any potential security holes. This is where AllowPartiallyTrustedCallersAttribute (APTCA) comes in. Without this attribute, fully-trusted assemblies run Critical code, and partially-trusted assemblies run Transparent code. When this attribute is applied to an assembly, it confirms that the assembly has had a full security audit, and it is safe to be called from untrusted code. All code in that assembly runs as Transparent, but SecurityCriticalAttribute and SecuritySafeCriticalAttribute can be applied to individual types and methods to make those run at the Critical or SafeCritical levels, with all the restrictions that entails. So, to allow the sandboxed assembly to call the full-trust API assembly, simply add APCTA to the API assembly: [assembly: AllowPartiallyTrustedCallers] and everything works as you expect. The sandboxed dll can call your API dll, and from there communicate with the rest of the application. Conclusion That’s the basics of running a full-trust assembly in a sandboxed appdomain, and allowing a sandboxed assembly to access it. The key is AllowPartiallyTrustedCallersAttribute, which is what lets partially-trusted code call a fully-trusted assembly. However, an assembly with APTCA applied to it means that you have run a full security audit of every type and member in the assembly. If you don’t, then you could inadvertently open a security hole. I’ll be looking at ways this can happen in my next post.

  • Process Centric Banking: Loan Origination Solution

    - by Manish Palaparthy
    There is an old proverb that goes, "The difference between theory and practice is greater in practice than in theory". So, we keep doing numerous "Proof of Concepts" with our own products on various business cases to analyze them deeply, understand and explain to our customers. We then present our learnings as they happened. The awareness of each PoC should help readers increase the trustworthiness of the results coming out of these PoCs. I present one such PoC where we invested a lot of time&effort.  Process Centric Banking : Loan Origination Solution Loan Origination is a process by which a borrower applies for a new loan and the lender processes that application. Loan origination includes the series of steps taken by the bank from the point the customer shows interest in a loan product all the way to disbursal of funds. The Loan Origination process is relevant for many kind of lenders in Financial services: Banks, Credit Unions, NBFCs(Non Banking Financial Companies) and so on. For simplicity sake, I will use "Bank" as the lending institution in the rest of my article.  Loan Origination is one of the core processes for Banks as it is the process by which the it creates assets against which the Institution earns most of its profits from. A well tuned loan origination process can affect the Bank in many positive ways. Banks have always shown great interest in automating the loan origination process for the above reason. However, due the constant changes in customer environment, market dynamics, prevailing economic conditions, cost pressures & regulatory environment they run into lot of challenges. Let me categorize some of these challenges for you Customer Environment Multiple Channels: Customer can use any of the available channels (Internet Banking, Email, Fax, Branch, Phone Banking, ATM, Broker, Mobile, Snail Mail) to perform all or some of the activities related to her Visibility into the origination process: Expect immediate update on the status of loan processing & alert messages Reduced Turn Around Time: Expect loans to be processed with least turn around time Reduced loan processing fees: Partly due to market dynamics the customer expects the loan processing fee to be negligible Market Dynamics Competitive environment:  The competition keeps creating many variants of loan products to attract customers, the bank needs to create similar product variants with better offers to attract customers or keep existing ones Ability to migrate loans from one vendor to another: It has become really easy for retail customers to move from one bank to the other given the low fee of loan processing and highly attractive offers. How does the bank protect it's customer base while actively engaging with potential customers banking with competitor banks Flexibility to react to market developments: Market development greatly influence loan processing, underwriting, asset valuation, risk mitigation rules. Can the bank modify rules and policies, the idea is not just to react to market developments but to pro-actively manage new developments Economic conditions Constant change in various rates and their implications on the rates and rules applied when on-boarding a loan: How quickly can the bank apply changes to rates offered to customers when the central bank changes various rates Requirements of Audit by the central banker: Tough economic conditions have demanded much more stringent audit rules and tests. The banks needs to produce ready reports(historic & operational) for audit compliance Risk Mitigation: While risk mitigation has always been a key concern for the bank, this is the area where the bank's underwriters & risk analysts spend the maximum time when processing a loan application. In order to reduce TAT the bank cannot compromise on its risk mitigation strategies Cost pressures Reduce Cost of processing per application: To deliver a reduced loan processing fee to the customer, the bank needs to keep its cost per processing loan application low. Meet customer TAT expectations while reducing the queues and the systems being used to process the loan application: The loan application could potentially be spending a lot of time waiting in the queue for further processing. Different volumes & patterns of applications demand different queuing algorithms. The bank needs to have real-time visibility into these queues and have the flexibility to change queuing algorithms at runtime  Increase the use of electronic communication and reduce the branch channel usage: Lesser automation leads not only leads to Increased turn around time, it also impacts more costs to reach out to customers The objective of our PoC was to implement a Loan Origination Solution whose ownership lies with the bank and effectively meet the challenges listed above. We built a simple story board for the solution We then went about implementing our storyboard using Oracle BPM Suite, Webcenter Content : Imaging. The web UI has been built on ADF technolgies, while the integration with core-services has been implemented using the underlying SOA infrastructure. The BPM process model is quite exhaustive can meet all the challenges listed above to reasonable degree. A bank intending to implement an end-to-end Loan Origination Solution has multiple options at it's disposal. It can Develop a customer Loan Origination Application from scratch: Gives maximum opportunity to build what you want but inflexible to upgrade and maintain. Higher TCO in long term Buy a Packaged application & customize it: Customizing a generic loan application can be tedious and prove as difficult as above. Build it using many disparate & un-integrated tools: Initially seems easier than developing from scratch. But, without integrated tool sets this is not a viable approach either or A solution based on a Framework: Independent Services and Business Process Modeling provide decoupled architecture that is flexible. We built this framework end-to-end with processes the core process of loan origination & several sub-processes such as Analyse and define customer needs, customer credit verification, identity check processes, legal review process, New customer registration & risk assessment.

  • MERGE gives better OUTPUT options

    - by Rob Farley
    MERGE is very cool. There are a ton of useful things about it – mostly around the fact that you can implement a ton of change against a table all at once. This is great for data warehousing, handling changes made to relational databases by applications, all kinds of things. One of the more subtle things about MERGE is the power of the OUTPUT clause. Useful for logging.   If you’re not familiar with the OUTPUT clause, you really should be – it basically makes your DML (INSERT/DELETE/UPDATE/MERGE) statement return data back to you. This is a great way of returning identity values from INSERT commands (so much better than SCOPE_IDENTITY() or the older (and worse) @@IDENTITY, because you can get lots of rows back). You can even use it to grab default values that are set using non-deterministic functions like NEWID() – things you couldn’t normally get back without running another query (or with a trigger, I guess, but that’s not pretty). That inserted table I referenced – that’s part of the ‘behind-the-scenes’ work that goes on with all DML changes. When you insert data, this internal table called inserted gets populated with rows, and then used to inflict the appropriate inserts on the various structures that store data (HoBTs – the Heaps or B-Trees used to store data as tables and indexes). When deleting, the deleted table gets populated. Updates get a matching row in both tables (although this doesn’t mean that an update is a delete followed by an inserted, it’s just the way it’s handled with these tables). These tables can be referenced by the OUTPUT clause, which can show you the before and after for any DML statement. Useful stuff. MERGE is slightly different though. With MERGE, you get a mix of entries. Your MERGE statement might be doing some INSERTs, some UPDATEs and some DELETEs. One of the most common examples of MERGE is to perform an UPSERT command, where data is updated if it already exists, or inserted if it’s new. And in a single operation too. Here, you can see the usefulness of the deleted and inserted tables, which clearly reflect the type of operation (but then again, MERGE lets you use an extra column called $action to show this). (Don’t worry about the fact that I turned on IDENTITY_INSERT, that’s just so that I could insert the values) One of the things I love about MERGE is that it feels almost cursor-like – the UPDATE bit feels like “WHERE CURRENT OF …”, and the INSERT bit feels like a single-row insert. And it is – but into the inserted and deleted tables. The operations to maintain the HoBTs are still done using the whole set of changes, which is very cool. And $action – very convenient. But as cool as $action is, that’s not the point of my post. If it were, I hope you’d all be disappointed, as you can’t really go near the MERGE statement without learning about it. The subtle thing that I love about MERGE with OUTPUT is that you can hook into more than just inserted and deleted. Did you notice in my earlier query that my source table had a ‘src’ field, that wasn’t used in the insert? Normally, this would be somewhat pointless to include in my source query. But with MERGE, I can put that in the OUTPUT clause. This is useful stuff, particularly when you’re needing to audit the changes. Suppose your query involved consolidating data from a number of sources, but you didn’t need to insert that into the actual table, just into a table for audit. This is now very doable, either using the INTO clause of OUTPUT, or surrounding the whole MERGE statement in brackets (parentheses if you’re American) and using a regular INSERT statement. This is also doable if you’re using MERGE to just do INSERTs. In case you hadn’t realised, you can use MERGE in place of an INSERT statement. It’s just like the UPSERT-style statement we’ve just seen, except that we want nothing to match. That’s easy to do, we just use ON 1=2. This is obviously more convoluted than a straight INSERT. And it’s slightly more effort for the database engine too. But, if you want the extra audit capabilities, the ability to hook into the other source columns is definitely useful. Oh, and before people ask if you can also hook into the target table’s columns... Yes, of course. That’s what deleted and inserted give you.

  • Giving a Bomberman AI intelligent bomb placement

    - by Paul Manta
    I'm trying to implement an AI algorithm for Bomberman. Currently I have a working but not very smart rudimentary implementation (the current AI is overzealous in placing bombs). This is the first AI I've ever tried implementing and I'm a bit stuck. The more sophisticated algorithms I have in mind (the ones that I expect to make better decisions) are too convoluted to be good solutions. What general tips do you have for implementing a Bomberman AI? Are there radically different approaches for making the bot either more defensive or offensive? Edit: Current algorithm My current algorithm goes something like this (pseudo-code): 1) Try to place a bomb and then find a cell that is safe from all the bombs, including the one that you just placed. To find that cell, iterate over the four directions; if you can find any safe divergent cell and reach it in time (eg. if the direction is up or down, look for a cell that is found to the left or right of this path), then it's safe to place a bomb and move in that direction. 2) If you can't find and safe divergent cells, try NOT placing a bomb and look again. This time you'll only need to look for a safe cell in only one direction (you don't have to diverge from it). 3) If you still can't find a safe cell, don't do anything. for $(direction) in (up, down, left, right): place bomb at current location if (can find and reach divergent safe cell in current $(direction)): bomb = true move = $(direction) return for $(direction) in (up, down, left, right): do not place bomb at current location if (any safe cell in the current $(direction)): bomb = false move = $(direction) return else: bomb = false move = stay_put This algorithm makes the bot very trigger-happy (it'll place bombs very frequently). It doesn't kill itself, but it does have a habit of making itself vulnerable by going into dead ends where it can be blocked and killed by the other players. Do you have any suggestions on how I might improve this algorithm? Or maybe I should try something completely different? One of the problems with this algorithm is that it tends to leave the bot with very few (frequently just one) safe cells on which it can stand. This is because the bot leaves a trail of bombs behind it, as long as it doesn't kill itself. However, leaving a trail of bombs behind leaves few places where you can hide. If one of the other players or bots decide to place a bomb somewhere near you, it often happens that you have no place to hide and you die. I need a better way to decide when to place bombs.

  • Overwrite previous output in Bash instead of appending it

    - by NES
    For a bash timer i use this code: #!/bin/bash sek=60 echo "60 Seconds Wait!" echo -n "One Moment please " while [ $sek -ge 1 ] do echo -n "$sek " sleep 1 sek=$[$sek-1] done echo echo "ready!" That gives me something like that One Moment please: 60 59 58 57 56 55 ... Is there a possibility to replace the last value of second by the most recent so that the output doesn't generate a large trail but the seconds countdown like a real time at one position? (Hope you understand what i mean :))

  • Generating geometry when using VBO

    - by onedayitwillmake
    Currently I am working on a project in which I generate geometry based on the players movement. A glorified very long trail, composed of quads. I am doing this by storing a STD::Vector, and removing the oldest verticies once enough exist, and then calling glDrawArrays. I am interested in switching to a shader based model, usually examples I see the VBO is generated at start and then that's basically it. What is the best route to go about creating geometry in real time, using shader / VBO approach

  • Yet Another SQL Strategy for Versioned Data

    There is a popular design for a database that requires a built-in audit-trail of amendments and additions, where data is never deleted, but merely superseded by a later version. Whilst this is conceptually simple, it has always made for complicated SQL for reporting the latest version of data. Alex joins the debate on the best way of doing this with an example using an indexed view and the filtered index.

  • windows azure thoughts.

    - by foxjazz
    Well I had a relatively unpleasant exprience with Microsoft's new offerings when it comes to azure.And of course they deleted the forum trail.They don't want the consumer as a customer, expect to pay $200 - $250 or more a year for azure and that doesn't include a good email solution. This is for the smallest slice offering.If you want a simple website solution 1and1.com isn't a bad choice and it's less than $50 a year.

  • Simulating water droplets on a window

    - by skyuzo
    How do I simulate water droplets realistically falling, gathering, and flowing down a window? For example, see http://www.youtube.com/watch?v=4jaGyv0KRPw. In particular, I want to simulate how smaller droplets merge together to form larger droplets that have enough weight to oppose the surface tension and flow downward, leaving a trail of water. I'm aware of fluid simulation, but how would it be applied in this situation?

  • Error in retrieving data from Excel File

    - by Sreejesh Kumar
    I have an excel file. I wanted to pull the data from excel file to SQL Server table. And the data is successfully transferred.In the excel file, I removed a text from one column named "Risk" from one row.The text was lengthy one.now the package execution fails at the source ie from the excel file. The errors are shown as "[Audit [1]] Error: There was an error with output column "Risk" (100) on output "Excel Source Output" (9). The column status returned was: "DBSTATUS_UNAVAILABLE"." and "[Audit [1]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "output column "Risk" (100)" failed because error code 0xC0209071 occurred, and the error row disposition on "output column "Risk" (100)" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure." the error occurs only when I remove this particular text from this row.
