• Top 5 Sites and Activities in San Francisco to Experience During Oracle OpenWorld

  - by kgee

  While Oracle OpenWorld may provide solutions and information on topics like how to simplify your IT, the importance of cloud, and what types of storage may satisfy your enterprise needs, who is going to tell you more about San Francisco? Here are some suggested sites and activities to experience after OpenWorld that aren’t too far from the Moscone Center. It is recommended to take a cab for the sake of time, but the 6 square miles that make up San Francisco will make for a quick trek to any of the following destinations: The Golden Gate BridgeAn image often associated with San Francisco, this bridge is one of the most impressive in the world. Take a walk across it, or view it from nearby Crissy Field, it is a sight that floors even the most veteran of San Franciscans. The Ferry BuildingLocated at the end of Market Street in the Embarcadero, the Ferry Building once served as a hub of water transport and trade. The building has a bay front view and an array of food choices and restaurants. It is easily accessible via the Muni, BART, trolley or by cab. It is a must-see in San Francisco, and not too far from the Moscone Center. Ride the Trolley to the CastroFor only $2, you can get go back in history for a moment on the Trolley. Take the F-line from the Embarcadero and ride it all the way to the Castro district. During the ride, you will get an overview of the landscape and cultures that are prevalent in San Francisco, but be wary that some areas may beg for an open mind more than others. Golden Gate ParkWhen you tire of the concrete jungle, the lucky part of being in San Francisco is that you can escape to a natural refuge, this park being one of the favorites. This park is known for its hiking trails, cultural attractions, monuments, lakes and gardens. It is one good reason to bring your sneakers to San Francisco, and is also a great place to picnic. Please be wary that it is easy to get lost, and it is advisable to bring a map (just in case) if you go. Haight AshburyFor a complete change of scenery, Haight Ashbury is known as one of the places hippies used to live and the location of "The Summer of Love." It is now a more affluent neighborhood with boutique shops and the occasional drum circle. While it may be perceived as grungy in certain spots, it is one of the most photographed places in San Francisco and an integral part of San Franciscan history.

• The Oracle Cash Management Secret Very Few Customers Know About

  - by Theresa Hickman

  Did you know that Oracle Cash Management has a robust positioning feature? I had no idea. I was under the mistaken impression that Oracle Cash Management only did bank statement reconciliations. It seems I am not alone. In fact, many Oracle Financials customers are also not aware of this even though it is delivered for free with the Oracle Financials license. Even better, last week, Oracle released an enhancement to Oracle Cash Management for Release 12 that will greatly help customers with their cash positioning needs. As we all know, credit is tight these days. Companies need better visibility of their cash and other liquidity positions to make better use of their cash resources. Today, many customers are managing their cash positions manually using spreadsheets. We also hear how many of them are maintaining larger than normal balances in numerous bank accounts because they just do not have the visibility, and therefore the comfort they need. Although spreadsheets may work in the short-term, they are not the best way to manage your cash positions for the long-term especially if you have dozens, or even hundreds of bank and brokerage accounts. Also, spreadsheets are a lot more risky because they can be overwritten, deleted, difficult to audit, etc. With the newly enhanced positioning feature in Oracle Cash Management, customers can manage their daily cash positions using an excel-like interface that is very flexible and user-configurable. You can link the worksheet to an unlimited number of bank accounts to automatically retrieve your opening balances, the current/intra-day cash inflows and outflows, as well as your expected cash flows from your Fx, Investment and Debt positions if you have Oracle's Treasury module . Oracle Cash Management also has direct integration with Oracle Receivables, Oracle Payables, and Payroll, which adds to the comprehensive picture of what's happening with your organizations' cash in real-time. Here's a screen shot of what the cash positioning page looks like: View image As you can see, your Treasurers can obtain a holistic view of all cash positions across any number of bank accounts as well as other sources of cash flow movements. Depending on how they manage their accounts, they can also use this feature to initiate or monitor bank account sweeps or transfers between their zero balance accounts (ZBA) or cash pools. The cash position worksheet provide drill down for more detail and the ability to manually enter items directly into the worksheet for even greater flexibility and control. The enhancements to this feature were released last week. The following list the patches for Release 12.0.6 and 12.1.1: For more information, visit the following website. http://launch.oracle.com.

• Naming Convention for Dedicated Thread Locking objects

  - by Chris Sinclair

  A relatively minor question, but I haven't been able to find official documentation or even blog opinion/discussions on it. Simply put: when I have a private object whose sole purpose is to serve for private lock, what do I name that object? class MyClass { private object LockingObject = new object(); void DoSomething() { lock(LockingObject) { //do something } } } What should we name LockingObject here? Also consider not just the name of the variable but how it looks in-code when locking. I've seen various examples, but seemingly no solid go-to advice: Plenty of usages of SyncRoot (and variations such as _syncRoot). Code Sample: lock(SyncRoot), lock(_syncRoot) This appears to be influenced by VB's equivalent SyncLock statement, the SyncRoot property that exists on some of the ICollection classes and part of some kind of SyncRoot design pattern (which arguably is a bad idea) Being in a C# context, not sure if I'd want to have a VBish naming. Even worse, in VB naming the variable the same as the keyword. Not sure if this would be a source of confusion or not. thisLock and lockThis from the MSDN articles: C# lock Statement, VB SyncLock Statement Code Sample: lock(thisLock), lock(lockThis) Not sure if these were named minimally purely for the example or not Kind of weird if we're using this within a static class/method. Several usages of PadLock (of varying casing) Code Sample: lock(PadLock), lock(padlock) Not bad, but my only beef is it unsurprisingly invokes the image of a physical "padlock" which I tend to not associate with the abstract threading concept. Naming the lock based on what it's intending to lock Code Sample: lock(messagesLock), lock(DictionaryLock), lock(commandQueueLock) In the VB SyncRoot MSDN page example, it has a simpleMessageList example with a private messagesLock object I don't think it's a good idea to name the lock against the type you're locking around ("DictionaryLock") as that's an implementation detail that may change. I prefer naming around the concept/object you're locking ("messagesLock" or "commandQueueLock") Interestingly, I very rarely see this naming convention for locking objects in code samples online or on StackOverflow. Question: What's your opinion generally about naming private locking objects? Recently, I've started naming them ThreadLock (so kinda like option 3), but I'm finding myself questioning that name. I'm frequently using this locking pattern (in the code sample provided above) throughout my applications so I thought it might make sense to get a more professional opinion/discussion about a solid naming convention for them. Thanks!

• What constitutes a "substantial, good-faith effort to remove the links"

  - by Luke McCallum

  We engaged the services of a 3rd party SEO consultant to assist us in managing our Meta data and to write regular blogs on our site http://cyberdesignworks.com.au Without our authorisation, the SEO also ran a link building campaign which has seen us Penguin slapped and we no longer appear in Google for a number of our core keywords. Since notification by Google that we have "unnatural links" back in March we have undertaken a significant campaign to rid ourselves of these dodgy backlinks by a number of methods. I have just received feedback on my 4th or 5th resubmission which is still advising that we need to make a "substantial, good-faith effort to remove the links" before Google will reconsider us for inclusion. After the effort that I have gone through to get links removed, I am now at a loss as to what else I can do to demonstrate "substantial, good-faith effort to remove the links". Below is a summary of the actions that we have taken to date. According to http://removem.com we had about 5584 back-linking domains. Of those we have successfully contacted and had removed links from 344 domains We ignored links from 625 domains as they were either legitimate press releases, natural backlinks or client websites containing an attribution link in the footer that points back to us. Due to our efforts, or the sites simply becoming defunct, removem.com reports that links from 3262 domains have been removed. We have contacted but are yet to receive feedback from 1666 domains so we can assume that the backlinks remain. We have configured an automatic 301 redirect for each of the links from these 1666 domains to point to http://redirects.sanscode.com/ which we are calling our Bad Link Catcher (a stroke of genius I thought). i.e http://www.mysimplewebdesign.com/create-a-perfect-webpage-with-four-important-tips-from-sydney-web-development-service-companies.php As we are a web design agency, we have a large number of client websites which contain an attribution link in their footer which points back to us. We have gone through the vast majority of these and updated these links to replace anchor text with an image and rel="nofollow" link. i.e <a rel="nofollow" target="_blank" href="http://www.cyberdesignworks.com.au/"><img src="https://sessions.sanscode.com/site/assets/media/badges/Badge_CDW_SANSCODE.png"></a> See http://www.milkatwork.com.au/ An export from http://removem.com detailing the number of times we have contacted each link and whether it is still found or not was also supplied with each resubmission. The total back links reported in Google Web Master Tools has dropped from over 100K to 87K and I expect it to drop significantly lower once Google re-crawls each back-linking page. Based on all of the above, I am not sure what else I can do to to demonstrate a "substantial, good-faith effort to remove the links". I would sincerely appreciate any feedback or suggestions that you may have as I am out of ideas.

• SQL Saturday #162 Cambridge

  - by Most Valuable Yak (Rob Volk)

  Despite the efforts of American Airlines, this past weekend I attended the first SQL Saturday in the UK!  Hosted by the SQLCambs Chapter of PASS and organized by Mark (b|t) & Lorraine Broadbent, ably assisted by John Martin (b|t), Mark Pryce-Maher (b|t) and other folks whose names I've unfortunately forgotten, it was held at the Crowne Plaza Hotel, which is completely surrounded by Cambridge University. On Friday, they presented 3 pre-conference sessions given by the brilliant American Cloud & DBA Guru, Buck Woody (b|t), the brilliant Danish SQL Server Internals Guru, Mark Rasmussen (b|t), and the brilliant Scottish Business Intelligence Guru and recent Outstanding Pass Volunteer, Jen Stirrup (b|t).  While I would have loved to attend any of their pre-cons (having seen them present several times already), finances and American Airlines ultimately made that impossible.  But not to worry, I caught up with them during the regular sessions and at the speaker dinner.  And I got back the money they all owed me.  (Actually I owed Mark some money) The schedule was jam-packed even with only 4 tracks, there were 8 regular slots, a lunch session for sponsor presentations, and a 15 minute keynote given by Buck Woody, who besides giving an excellent history of SQL Server at Microsoft (and before), also explained the source of the "unknown contact" image that appears in Outlook.  Hint: it's not Buck himself. Amazingly, and against all better judgment, I even got to present at SQL Saturday 162!  I did a 5 minute Lightning Talk on Regular Expressions in SSMS.  I then did a regular 50 minute session on Constraints.  You can download the content for the regular session at that link, and for the regular expression presentation here. I had a great time and had a great audience for both of my sessions.  You would never have guessed this was the first event for the organizers, everything went very smoothly, especially for the number of attendees and the relative smallness of the space.  The event sponsors also deserve a lot of credit for making themselves fit in a small area and for staying through the entire event until the giveaways at the very end. Overall this was one of the best SQL Saturdays I've ever attended and I have to congratulate Mark B, Lorraine, John, Mark P-M, and all the volunteers and speakers for making this an astoundingly hard act to follow!  Well done!

• How to impale and stack targets correctly according to the collider and its coordinate?

  - by David Dimalanta

  I'm making another simple game, a catch game, where a spawning target game object must be captured using a skewer to impale it. Here how: At the start, the falling object (in red) will fall in a vertical direction (in blue) When aimed properly, the target will fall down along the line of the skewer. (in blue) Then, another target is spawned and will fall vertically. (in red) When aimed successfully again in a streak, the second target will fall along the skewer and stacked. Same process over and over when another target is spawned. However, when I test run it on the scene tab in Unity, when impaled several targets, instead of a smooth flow and stacking it ended up overlaying it instead of stacking it up like a pancake. Here's what it look like: As I noticed when reaching the half-way of my progress, I tried to figure out how to deal with collider bodies without sticking each other so that it will actually stack like in the example of the image at no. 3. Here's the script code I added in the target game object: using UnityEngine; using System.Collections; public class ImpaleStateTest : MonoBehaviour { public GameObject target; public GameObject skewer; public bool drag = false; private float stack; private float impaleCount; void Start () { stack = 0; impaleCount = 0; } void Update () { if(drag) { target.transform.position = new Vector3 (DragTest.dir.transform.position.x, DragTest.dir.transform.position.y - 0.35f, 0); target.transform.rotation = DragTest.degrees; target.rigidbody2D.fixedAngle = true; target.rigidbody2D.isKinematic = true; target.rigidbody2D.gravityScale = 0; if(Input.GetMouseButton(0)) { Debug.Log ("Skewer: " + DragTest.dir.transform.position.x); Debug.Log ("Target: " + target.transform.position.x); } } } void OnTriggerEnter2D(Collider2D collider) { impaleCount++; Debug.Log ("Impaled " + impaleCount + " time(s)!"); drag = true; audio.Play (); } } Aside from that, I'm not sure if it's right but, the only way to stick the impaled targets while dragging the skewer left or right is to get the X coordinates from the skewer only. Is there something else to recommend it in order to improve this behavior as realistic as possible? Please help.

• GPL vs plugin interfaces not designed with a specific application in mind

  - by Kristóf Marussy

  I am not seeking or in need of legal advice, but an interesting though experiment came to my mind. Imagine the following situtation (I cannot really think about a concrete example and I am unsure if a real manifestation even exists): there is a free (libre) api A licensed under some permissive license or even LGPL. Non-free application B implements this api in order host plugins, but there are other free software doing the same thing. Moreover, there is plugin C acting as a plugin under api A. It links to library D, that is under GPL, so C is also under GPL. Plugins using A are loaded into hosts via a dlopen-like mechanism and use complex data structure for host-plugin communication. Neither B nor C distribute any files that may be required for A to function properly (like headers containing the structure definitions of A or dynamic libraries containing helper functions for A written by the authors of A), but such things may exist. Now some user installs application B and plugin C on his machine, along with anything that may be required for api A to function properly. Then he proceeds and loads C into B and creates some intellectual property with B which is not a piece of software. Did a GPL violation happend at some point, and if so, who violated GPL and why? The authors of C violate D's license by making C possible to be used in non-free host B? This is a possibility because they can't give and exception of GPL (like one described in http://www.gnu.org/licenses/gpl-faq.html#GPLPluginsInNF or http://www.gnu.org/licenses/gpl-faq.html#LinkingOverControlledInterface) due to D's license terms. The authors of B violate C's and D's license by making C possible to be loaded in B? This is a possibility because http://www.gnu.org/licenses/gpl-faq.html#NFUseGPLPlugins disallows the mechanisms A uses for communitation between the free and non-free modules. The authors of A, because the api may be used (and in this case, was used) for communication between GPL'd and non-free software. This would be extremely absurd. The user, because at the moment of loading B into C, he made a derived work of C. I think this is impossible, because he does not distribute it. But would the situation change is he decided to release a configuration file of B which makes B load C as a plugin? Nobody, because A counts as a 'system library', and both B and C directly interact only with A, not eachother. In a sane world, this would happen... A concrete example of A could be some kind of audio (think LADSPA) or image processing api. However, I could find no such interface (that is free software, generic and is also implemented by commercial tools). A real-world example could also be quite enlightening.

• Customizing Flowcharts in Oracle Tutor

  - by [email protected]

  Today we're going to look at how you can customize the flowcharts within Oracle Tutor procedures, and how you can share those changes with other authors within your company. Here is an image of a flowchart within a Tutor procedure with the default size and color scheme. You may want to change the size of your flowcharts as your end-users might have larger screens or need larger fonts. To change the size and number of columns, navigate to Tutor Author Author Options Flowcharts. The default is to have 4 columns appear in each flowchart, but, if I change it to six, my end-users will see a denser flowchart. This might be too dense for my end-users, so I will change it to 5 columns, and I will also deselect the option to have separate task boxes. Now let's look at how to customize the colors. Within the Flowchart options dialog, there is a button labeled "Colors." This brings up a dialog box of every object on a Tutor flowchart, and I can modify the color of each object, as well as the text within the object. If I click on the background, the "page" object appears in the Item field, and now I can customize the color and the title text by selecting Select Fill Color and/or Select Text Color. A dialog box with color choices appears. If I select Define Custom Colors, I can make my selections even more precise. Each time I change the color of an object, it appears in the selection screen. When the flowchart customization is finished, I can save my changes by naming the scheme. Although the color scheme I have chosen is rather silly looking, perhaps I want others to give me their feedback and make changes as they wish. I can share the color scheme with them by copying the FCP.INI file in the Tutor\Author directory into the same directory on their systems. If the other users have color schemes that they do not want to lose, they can copy the relevant lines from the FCP.INI file into their file. If I flowchart my document with the new scheme, I can see how it looks within the document. Sometimes just one or two changes to the default scheme are enough to customize the flowchart to your company's color palette. I have seen customers who have only changed the Start object to green and the End object to red, and I've seen another customer who changed every object to some variant of black and orange. Experiment! And let us know how you have customized your flowcharts. Mary R. Keane Senior Development Director, Oracle Tutor

• Extensible Metadata in Oracle IRM 11g

  - by martin.abrahams

  Another significant change in Oracle IRM 11g is that we now use XML to create the tamperproof header for each sealed document. This article explains what this means, and what benefit it offers. So, every sealed file has a metadata header that contains information about the document - its classification, its format, the user who sealed it, the name and URL of the IRM Server, and much more. The IRM Desktop and other IRM applications use this information to formulate the request for rights, as well as to enhance the user experience by exposing some of the metadata in the user interface. For example, in Windows explorer you can see some metadata exposed as properties of a sealed file and in the mouse-over tooltip. The following image shows 10g and 11g metadata side by side. As you can see, the 11g metadata is written as XML as opposed to the simple delimited text format used in 10g. So why does this matter? The key benefit of using XML is that it creates the opportunity for sealing applications to use custom metadata. This in turn creates the opportunity for custom classification models to be defined and enforced. Out of the box, the solution uses the context classification model, in which two particular pieces of metadata form the basis of rights evaluation - the context name and the document's item code. But a custom sealing application could use some other model entirely, enabling rights decisions to be evaluated on some other basis. The integration with Oracle Beehive is a great example of this. When a user adds a document to a Beehive workspace, that document can be automatically sealed with metadata that represents the Beehive security model rather than the context model. As a consequence, IRM can enforce the Beehive security model precisely and all rights configuration can actually be managed through the Beehive UI rather than the IRM UI. In this scenario, IRM simply supports the Beehive application, seamlessly extending Beehive security to all copies of workspace documents without any additional administration. Finally, I mentioned that the metadata header is tamperproof. This is obviously to stop a rogue user modifying the metadata with a view to gaining unauthorised access - reclassifying a board document to a less sensitive classifcation, for example. To prevent this, the header is digitally signed and can only be manipulated by a suitably authorised sealing application.

• If unexpected database changes cause you problems – we can help!

  - by Chris Smith

  Have you ever been surprised by an unexpected difference between you database environments? Have you ever found that your Staging database is not the same as your Production database, even though it was the week before? Has an emergency hotfix suddenly appeared in Production over the weekend without your knowledge? Has your client secretly added a couple of indices to their local version of the database to aid performance? Worse still, has a developer ever accidently run a SQL script against the wrong database without noticing their mistake? If you’ve answered “Yes” to any of the above questions then you’ve suffered from ‘drift’. Database drift is where the state of a database (schema, particularly) has moved away from its expected or official state over time. The upshot is that the database is in an unknown or poorly-understood state. Even if these unexpected changes are not destructive, drift can be a big problem when it’s time to release a new version of the database. A deployment to a target database in an unexpected state can error and fail, potentially delaying a vital, time-sensitive update. A big issue with drift is that it can be hard to spot and it can be even harder to determine its provenance. So, before you can deal with an issue caused by drift, you’ll need to know exactly what change has been made, who made it, when they made it and why they made it. Those questions can take a lot of effort to answer. Then you actually need to decide what to do. Do you rollback the change because it was bad? Retrospectively apply it to the Staging environment because it is a required change? Or script the change into version control to get it back in line with your process? Red Gate’s Database Delivery Team have been talking to DBAs, database consultants and database developers to explore the problem of drift. We’ve started to get a really good idea of how big a problem it can be and what database professionals need to know and do, in order to deal with it.  It’s fair to say, we’re pretty excited at the prospect of creating a tool that will really help and we’ve got some great feedback on our initial ideas (see image below).   We’re now well underway with the development of our new drift-spotting product – SQL Lighthouse – and we hope to have a beta release out towards the end of July. What we really need is your help to shape the product into a great tool. So, if database drift is a problem that you’d like help solving and are interested in finding out more about our product, join our mailing list to register your interest in trying out the beta release.

• SQL SERVER – How to easily work with Database Diagrams

  - by Pinal Dave

  Databases are very widely used in the modern world. Regardless of the complexity of a database, each one requires in depth designing. To practice along please Download dbForge Studio now.  The right methodology of designing a database is based on the foundations of data normalization, according to which we should first define database’s key elements – entities. Afterwards the attributes of entities and relations between them are determined. There is a strong opinion that the process of database designing should start with a pencil and a blank sheet of paper. This might look old-fashioned nowadays, because SQL Server provides a much wider functionality for designing databases – Database Diagrams. When using SSMS for working with Database Diagrams I realized two things – on the one hand, visualization of a scheme allows designing a database more efficiently; on the other – when it came to creating a big scheme, some difficulties occurred when designing with SSMS. The alternatives haven’t taken long to wait and dbForge Studio for SQL Server is one of them. Its functions offer more advantages for working with Database Diagrams. For example, unlike SSMS, dbForge Studio supports an opportunity to drag-and-drop several tables at once from the Database Explorer. This is my opinion but personally I find this option very useful. Another great thing is that a diagram can be saved as both a graphic file and a special XML file, which in case of identical environment can be easily opened on the other server for continuing the work. During working with dbForge Studio it turned out that it offers a wide set of elements to operate with on the diagram. Noteworthy among such elements are containers which allow aggregating diagram objects into thematic groups. Moreover, you can even place an image directly on the diagram if the scheme design is based on a standard template. Each of the development environments has a different approach to storing a diagram (for example, SSMS stores them on a server-side, whereas dbForge Studio – in a local file). I haven’t found yet an ability to convert existing diagrams from SSMS to dbForge Studio. However I hope Devart developers will implement this feature in one of the following releases. All in all, editing Database Diagrams through dbForge Studio was a nice experience and allowed speeding-up the common database designing tasks. Download dbForge Studio now.

• BizTalk 2009 - Creating a Custom Functoid Library

  If you find that you have a need to created multiple Custom Functoids you may also choose to create a Custom Functoid Library - a single project containing many custom functoids.  As previsouly discussed, the Custom Functoid Wizard can be used to create a project with a new custom functoid inside.  But what if you want to extend this project to include more custom functoids and create your Custom Functoid Library?  First create a Custom Functoid Library project and your first Custom Functoid using the Custom Functoid Wizard. When you open your Custom Functoid Library project in Visual Studio you will see that it contains your custom functoid class file along with its resource file.  One of the items this resource file contains is the ID of the the custom functoid.  Each custom functoid needs a unique ID that is over 6000.  When creating a Custom Functoid Library I would first suggest that you delete the ID from this resource file and instead create a _FunctoidIDs class containing constants for each of your custom functoids.  In this way you can easily see which custom functoid IDs are assigned to which custom functoid and which ID is next in the sequence of availability: namespace MyCompany.BizTalk.Functoids.TestFunctoids {     class _FunctoidIDs     {         public const int TestFunctoid                       = 6001;     } } You will then need to update the base() function in your existing functoid class to reference these constant values rather than the current resource file. From:    int functoidID;    // This has to be a number greater than 6000    functoidID = System.Convert.ToInt32(resmgr.GetString("FunctoidId"));    this.ID = functoidID; To: this.ID = _FunctoidIDs.TestFunctoid; To create a new custom functoid you can copy the existing custom functoid, renaming the resultant class file as appropriate.  Once it is renamed you will need to change the Class name, ResourceName reference and Base function name in the class code to those of your new custom functoid.  You will also need to create a new constant value in the _FunctoidIDs class and update the ID reference in your code to match this.  Assuming that you need some different functionalty from your new  customfunctoid you will need to check or amend the following in your functoid class file: Min and Max connections Functoid Category Input and Output connection types The parameters and functionality of the Execute function To change the appearance of you new custom functoid you will need to check or amend the following in the functoid resource file: Name Description Tooltip Exception Icon You can change the String values by double clicking the resource file and amending the value fields in the string table. To amend the functoid icon you will need to create a 16x16 bitmap image.  Once you have saved this you are then ready to import it into the functoid resource file.  In Visual Studio change the resource view to images, right click the icon and choose import from file. You have now completed your new custom functoid and created a Custom Functoid Library.  You can test your new library of functoids by building the project, copying the resultant DLL to C:\Program Files\Microsoft BizTalk Server 2009\Developer Tools\Mapper Extensions and then resetting the toolbox in Visual Studio.

• Simple heart container script for 2D game (Unity)?

  - by N1ghtshade3

  I'm attempting to create a simple mobile game (C#) that involves a simple three-heart life system. After searching for hours online, many of the solutions use OnGUI (which is apparently horrible for performance) and the rest are too complicated for me to understand and add to my code. The other solutions involve using a single texture and just hiding part of it when damage is taken. In my game, however, the player should be able to go over three hearts (for example, every 100 points). Sebastian Lague's Zelda-Style Health is what I'm looking for, but even though it's a tutorial there is way too much going on that I don't need or can't customize to fit in mine. What I have so far is a script called HealthScript.cs which contains a variable lives. I have another script, PlayerPhysics.cs which calls HealthScript and subtracts a life when an enemy is hit. The part I don't get is actually drawing the hearts. I think I understand what needs to happen, I just am not experienced enough with Unity to know how. The Start function should draw three (or whatever lives is set to) hearts in the top right corner. Since the game should be resolution-independent to accommodate the various sizes of Android devices, I'd rather use scaling rather than PixelInset. When the player hits an enemy as detected by PlayerPhysics.cs, it should subtract from lives. I think that I have this working using this.GetComponent<HealthScript>().lives -= 1 but I'm not sure if it actually works. This should trigger a redraw of the hearts so that there are now two hearts. The same principle would apply for adding hearts when a score is reached, except when lives > maxHeartsPerRow, the new hearts should be drawn below the old ones. I realise I don't have much code to show but believe me; I've tried for quite some time to figure this out and have little to show for it. Any help at all would be welcome; it seems like it shouldn't take that much code to put an image on the screen for each life there is, but I haven't found anything yet. Thanks!

• What Am I doing for my 5 months 1 week old baby for his first cold?

  - by Rekha

  With my limited friends circle with babies, I heard that babies in their fifth month usually gets affected by cold all of a sudden. This is unavoidable and I feel it is good for the babies as they start developing their immune system right on. We usually take our son for a small walk so that he is able to explore the world out there. We have been taking him for a stroll almost everyday since we was 3 months old. But only now he is getting his first cold. So things happen only now I think. Till that day I had somehow brought some routine for him for his feed and naps during day time. Night time is still sleepless ones anyway. So when he first got his cold, that night it went on as usual getting up every few hours. From the next day on, he stopped feeding at the usual time. In the night he goes for 8-10 hours between feeds but still wakes up every two hours and cries for about 10 minutes and when we lift him for sometime, he goes back to sleep. Now to the point what all to expect: * Babies starts feeding frequently * Babies spit up increases * They dislike the food they liked before (we have just started solid foods as per our pediatricians advice) * Since they cannot breathe properly, they cannot sleep for a long time *Pees and poops less frequently. What all we did for our baby to make him comfortable during this time: * Feed the baby less quantity and more frequently whenever they expect to feed (Do not follow the schedule) * When the quantity is less, spit ups is also less * If the baby does not like the food (vegetable or fruit), avoid them till they get back to normal * Try to elevate their head while sleeping ( we used the cradle – sitting position, bouncer, car seat and finally all four sides we placed firm pillows so that he does not roll and kept a pillow for his head till his hip – this one is recommended usually but we have an eye on him always) * No need for any medicines – it will take a week for them to get back to normal whether or not we gives medicines * We applied home made Cold Reliever (heat 2 teaspoons of coconut oil with a small camphor piece till the camphor disappears – then cool the mixture) on his chest, back, neck and feet and covered the feet with socks in the nights * Bathe him everyday – hot (that your baby can withstand) *  Whenever possible give him a steam bath (open the hot showers for sometime in the bathroom and close the doors. When the steam is bearable, close the shower and take the baby inside the bathroom for sometime) * Also use a bulb syringe provided in the hospital to clear the nose (use some saline water drops for ease) * Cuddle him when he cries But please do take him to his doctor if he has fever and other symptoms other than cold or the cold persists for more than 5 – 7 days.

• Given the presentation model pattern, is the view, presentation model, or model responsible for adding child views to an existing view at runtime?

  - by Ryan Taylor

  I am building a Flex 4 based application using the presentation model design pattern. This application will have several different components to it as shown in the image below. The MainView and DashboardView will always be visible and they each have corresponding presentation models and models as necessary. These views are easily created by declaring their MXML in the application root. <s:HGroup width="100%" height="100%"> <MainView width="75% height="100%"/> <DashboardView width="25%" height="100%"/> </s:HGroup> There will also be many WidgetViewN views that can be added to the DashboardView by the user at runtime through a simple drop down list. This will need to be accomplished via ActionScript. The drop down list should always show what WidgetViewN has already been added to the DashboardView. Therefore some state about which WidgetViewN's have been created needs to be stored. Since the list of available WidgetViewN and which ones are added to the DashboardView also need to be accessible from other components in the system I think this needs to be stored in a Model object. My understanding of the presentation model design pattern is that the view is very lean. It contains as close to zero logic as is practical. The view communicates/binds to the presentation model which contains all the necessary view logic. The presentation model is effectively an abstract representation of the view which supports low coupling and eases testability. The presentation model may have one or more models injected in in order to display the necessary information. The models themselves contain no view logic whatsoever. So I have a several questions around this design. Who should be responsible for creating the WidgetViewN components and adding these to the DashboardView? Is this the responsibility of the DashboardView, DashboardPresentationModel, DashboardModel or something else entirely? It seems like the DashboardPresentationModel would be responsible for creating/adding/removing any child views from it's display but how do you do this without passing in the DashboardView to the DashboardPresentationModel? The list of available and visible WidgetViewN components needs to be accessible to a few other components as well. Is it okay for a reference to a WidgetViewN to be stored/referenced in a model? Are there any good examples of the presentation model pattern online in Flex that also include creating child views at runtime?

• Leveraging Social Networks for Retail

  - by David Dorf

  For retailers, social media is all about B2C2C. That is, Business to Consumer to Consumer, or more specifically, retailer to influencer to consumer. Traditional marketing targeted mass media, trying to expose the message to as many people as possible. While effective, this approach has never been very efficient, with high costs for relatively low penetration. Then it was thought that marketers should focus their efforts on a relative few super-influencers that would then sway the masses. History shows a few successes with this approach but lacked any consistency or predictability. After all, if super-influencers were easy to find, most campaigns would easily go viral. Alas, research shows that most wide-spread trends were the result of several fortunate events, including some luck. So do people exert influence over each other when it comes to purchase decisions? Of course they do, all the time. But that influence is usually limited to a small set of friends and specific specialization. For instance, although I have 165 friends on Facebook, I am only able to influence my close friends and family on PC purchases, and I have no sway at all for fashion purchases. People trust my knowledge on technology, but nobody asks my advice on shoes. How then should retailers leverage social networks in order to reinforce brand image and push promotions? Two obvious ways are Like and Share. Online advertisements or wall-postings receive more clicks when the viewer sees that friends have "liked" the posting. That's our modern-day version of word-of-mouth advertising. Statistics show that endorsements from friends make it more likely a person will engage. If my friends and I liked it, then I might also "share" (or "retweet" in the case of Twitter) it with other friends. In that case the retailer has paid for X showings of the advertisement, but sharing has pushed it to an additional Y people at no cost. And further, the implicit endorsement by the sharer makes it more likely the recipient will engage. So a good first step is to find people active in social networks that will Like and Share in order to exert influence. Its still tough to go viral, but doubling engagement is still a big step in the right direction. More complex social graph analysis would be a second step, but I'll leave that topic for another day. If you're interested in the academic side of social dynamics, I suggest reading Duncan Watts' work.

• ZTE USB Modem AC2736, connection not possible in Ubuntu 12.04.1 LTS

  - by Fredo

  It's a long post but nearly covers all my experiments and changes I did to my NM. Hope the information is complete and if there are still question, more information can be provided. I've a ZTE AC2736 USB Modem (CDMA modem) which worked fine in Ubuntu 10.04 /11.10. I recently switched to 12.04.1 (precise pangolin). after the switch the first issue I faced was to connect to internet using my USB modem (ISP: Reliance Brand: Netconnect). Tried to run the drivers provided by Reliance but they are old and won't support Kernel 2.6.30 above. since the code was not downloaded with ISO image (of 12.04) i couldn't compile the files provided in such driver. lsusb does detect it as Modem with output similar to 19d2:fff1 ZTE CDMA technologies inc. (or similar as i didn't note it down) If it is detected as USB storage it shows 19d2:fff5 (as per few online forums, i may be wrong here). I used the network Manager and configured the modem to dial #777 (default) and the ISP provided username:password combination. It tries to connect to internet (3-4 times automatically)but fails to get online. once I was able to connect in the monring hours and the message was flashed 'registered on CDMA home network'. I was able to run an update. the kernel was updated with 3.0.2 -pae OR something similar (can find out if required). I surfed the net for about 2 hours later before restarting. After the restart, again the Modem was not able to get me online. I kept trying for many times. I tried changing the setting in NM. One evening after dark I was able to connect to network with same message flash 'registered on CDMA home network' (the message was similar, i'm not precise here,sorry). I was able to surf the net for nearly 3 hours before I switched off my Laptop. I'm not able to get online after that day, It's been 3 days now. I'll try the observered theory of late/early hours sometime soon as mentioned below. Laptop configuration : Make: Lenovo Model: B480 Processor: Intel B950 RAM: 4G DDR3 HDD: 500 G Broadcom Wireless/Bluetooth/Ethernet LAN OS: FreeDOS / Ubuntu 12.04 LTS (dualboot) Kernel 3.0.2-pae Obeservation : I'm able to connect to internet in those hours when generally the speed is high (low usage by other network (wireless) users). like in early mornings or late nights. This is strange as connection should not be dependent on bandwidth usage. Any help would be appraciated to fix this issue. before I decide to cahnge the OS or ISP.

• Social Analytics and the Customer

  - by David Dorf

  Many successful retailers put the customer at the center of everything they do, so its important that the customer is modeled correctly across all their systems.  The path to omni-channel starts and ends with the customer so at ARTS, our next big project is focused on ensuring a consistent representation of customers across our transactional data model, datawarehouse model, and XML schemas.  Further, we've started a new whitepaper that describes how Big Data and Social Media Analytics should be leveraged by retailers to add and additional level of customer insight. Let's start by taking a closer look at the meaning of social analytics.  Here's my definition: Social Analytics, in the retail context, describes the analysis of data obtained from social media sources in an effort to better comprehend and interact with the community of consumers.  This discipline seeks to understand what’s being said by the community about brands and products (“monitoring”), as well as understand the behaviors of those in the community (“profiling”).  The results are used to enforce the brand image, improve product decisions, and better focus marketing, all of which lead to increased sales. To help illustrate the facets of social analytics, I drew the diagram below which was originally published by Retail Touchpoints. There are lots of tools on the market that allow retailers to monitor social media for brand and product mentions.  These include analysis of sentiment, reach, share of voice, engagement, etc.  When your brand is mentioned, good or bad, its an opportunity to engage with the customer and possibly lead to a sale.  Because products are not always unique, its much more difficult to monitor product mentions, but detecting product trends early can help a retailer make better merchandising decisions, especially in fashion. Once a retailer understands what's being said, the next step is learn more about who's saying it.  That involves profiling customers beyond simple demographics to understand their motivations.  Much can be learned from patterns, and even more when customers voluntarily share their data.  Knowing that a customer is passionate about, for example, mountain biking allows the retailer to make relevant offers on helmets, ask for opinions on hydration, and help spread marketing messages. Social analytics has many facets that benefit retailers, some of which are easy but many of which are hard.  Its important for the CMO and CIO to work closely together to plan for these capabilities and monitor the maturity of tools on the market.  This is an area that will separate winners from losers.

• Should I be an algorithm developer, or java web frameworks type developer?

  - by Derek

  So - as I see it, there are really two kinds of developers. Those that do frameworks, web services, pretty-making front ends, etc etc. Then there are developers that write the algorithms that solve the problem. That is, unless the problem is "display this raw data in some meaningful way." In that case, the framework/web developer guy might be doing both jobs. So my basic problem is this. I have been an algorithms kind of software developer for a few years now. I double majored in Math and Computer science, and I have a master's in systems engineering. I have never done any web-dev work, with the exception of a couple minor jobs, and some hobby level stuff. I have been job interviewing lately, and this is what happens: Job is listed as "programmer- 5 years of experience with the following: C/C++, Java,Perl, Ruby, ant, blah blah blah" Recruiter calls me, says they want me to come in for interview In the interview, find out they have some webservices development, blah blah blah When asked in the interview, talk about my experience doing algorithms, optimization, blah blah..but very willing to learn new languages, frameworks, etc Get a call back saying "we didn't think you were a fit for the job you interviewed wtih, but our algorithm team got wind of you and wants to bring you on" This has happened to me a couple times now - see a vague-ish job description looking for a "programmer" Go in, find out they are doing some sort of web-based tool, maybe with some hardcore algorithms running in the background. interview with people for the web-based tool, but get an offer from the algorithms people. So the question is - which job is the better job? I basically just want to get a wide berth of experience at this level of my career, but are algorithm developers so much in demand? Even more so than all these supposed hot in demand web developer guys? Will I be ok in the long run if I go into the niche of math based algorithm development, and just little to no, or hobby level web-dev experience? I basically just don't want to pigeon hole myself this early. My salary is already starting to get pretty high - and I can see a company later on saying "we really need a web developer, but we'll hire this 50k/year college guy, instead of this 100k/year experience algorithm guy" Cliffs notes: I have been doing algorithm development. I consider myself to be a "good programmer." I would have no problem picking up web technologies and those sorts of frameworks. During job interviews, I keep getting "we think you've got a good skillset - talk to our algorithm team" instead of wanting me to learn new skills on the job to do their web services or whhatever other new technology they are doing. Edit: Whenever I am talking about algorithm development here - I am talking about the code that produces the answer. Typically I think of more math-based algorithms: solving a financial problem, solving a finite element method, image processing, etc

• Create Shortcuts for Your Favorite or Most Used Folders in Ubuntu

  - by Asian Angel

  Do you have certain folders that you access often each day but are only available through the Places Menu or Nautilus? See how easy it is to create shortcuts for your desktop and taskbar with our quick tutorial. To get started open Nautilus and locate the folders that you want to make new shortcuts for. For our example we chose Ubuntu One. Right click on the chosen folder and select Make Link. Your new shortcut will appear with the text Link to “Folder Name” and an Arrow Shortcut Marker attached. If you are happy with your new shortcut as is, then drag it to your desktop or taskbar as desired. We created the shortcut twice in our example…once for the desktop and once for the taskbar. For our example we decided to customize the taskbar shortcut a bit. To customize your shortcut right click on the shortcut and select Properties. Note: The desktop shortcut is limited on the amount you can customize it (name change and addition of up to four emblems to the folder). From here you can rename the shortcut and change the icon as desired. A quick name change and new icon made a huge improvement in how our taskbar shortcut looked. Note: The link for the icon we used is shown below. A little touch-up to our desktop shortcut and both are looking good.

• Remote synchronization

  - by Tomas Mysik

  Hi all, today we would like to show you another improvement we have prepared for NetBeans 7.2. Today, let's talk a little bit about remote synchronization. If you already use our simple (S)FTP client, this enhancement could be useful for you. Simply right click on Source Files and select Synchronize. Please notice that the remote synchronization works better only on the whole project (it means that the Source Files must be selected). The Synchronize action is also available on individual files (more files can be selected at once) but the suggested operation (download, upload etc.) does not work so precisely. Also please notice that the suggested operations are not 100% reliable since the timestamps provided by FTP servers are not exact. Once the remote files (their names and paths only, of course) are fetched, the main dialog appears: As you can see, NetBeans tries to suggest you operations (upload, download etc.) which should be done for each individual file of your project. If you are interested only in some particular changes, you can simply filter the list: Since we have a file conflict, we need to resolve it first. Fortunately this is very easy because we just select the desired file and click the Diff button . The remote version of our file is downloaded and compared with the local version. The resut is displayed in the dialog where you can easily apply and/or refuse the remote changes or even simply type manually to the local version of the selected file: Once we are done with our changes, the operation for the selected file changes to Upload and the file is marked with * (since we made some changes). Please notice that if you now click the Cancel button, in fact no changes are done in our local file. As you can see, if we have one or more files selected, we can change their operation to: no operation (file won't be synchronized) download upload delete (both local and remote file) reset (the operation is resetted to the original one suggested by NetBeans and also all changes done via Diff action are discarded) Now we are ready to synchronize our project. NetBeans will show us the synchronization summary (this dialog can be omitted, see the Show Summary checkbox on the previous image). The synchronization itself starts and we can see its progress and of course its result. As always, all the operations can be reviewed in the Output window. That's all for today, as always, please test it and report all the issues or enhancements you find in NetBeans BugZilla (component php, subcomponent FTP support).
