• Joy! | Important Information About Your iPad 3G

  - by Jeff Julian

  Looks like I was one of the lucky 114,000 who AT&T lost their email to “hackers”.  Why is “hackers” in “double quotes”.  I can just imagine some executive at AT&T in their “Oh No, We Messed Up Meeting” saying, what happened?  Then someone replied, well we have had a breach and “hackers” broke in (using the quote in the air gesture) and stole our iPad 3G customers emails. Oh well, I am sure my email has been sold and sold again by many different vendors, why not AT&T now.  At least Dorothy Attwood could have gave us her email to give to someone else instead of blinking it through a newsletter system. June 13, 2010 Dear Valued AT&T Customer, Recently there was an issue that affected some of our customers with AT&T 3G service for iPad resulting in the release of their customer email addresses. I am writing to let you know that no other information was exposed and the matter has been resolved.  We apologize for the incident and any inconvenience it may have caused. Rest assured, you can continue to use your AT&T 3G service on your iPad with confidence. Here’s some additional detail: On June 7 we learned that unauthorized computer “hackers” maliciously exploited a function designed to make your iPad log-in process faster by pre-populating an AT&T authentication page with the email address you used to register your iPad for 3G service.  The self-described hackers wrote software code to randomly generate numbers that mimicked serial numbers of the AT&T SIM card for iPad – called the integrated circuit card identification (ICC-ID) – and repeatedly queried an AT&T web address.   When a number generated by the hackers matched an actual ICC-ID, the authentication page log-in screen was returned to the hackers with the email address associated with the ICC-ID already populated on the log-in screen. The hackers deliberately went to great efforts with a random program to extract possible ICC-IDs and capture customer email addresses.  They then put together a list of these emails and distributed it for their own publicity. As soon as we became aware of this situation, we took swift action to prevent any further unauthorized exposure of customer email addresses.  Within hours, AT&T disabled the mechanism that automatically populated the email address. Now, the authentication page log-in screen requires the user to enter both their email address and their password. I want to assure you that the email address and ICC-ID were the only information that was accessible. Your password, account information, the contents of your email, and any other personal information were never at risk.  The hackers never had access to AT&T communications or data networks, or your iPad.  AT&T 3G service for other mobile devices was not affected. While the attack was limited to email address and ICC-ID data, we encourage you to be alert to scams that could attempt to use this information to obtain other data or send you unwanted email. You can learn more about phishing by visiting the AT&T website. AT&T takes your privacy seriously and does not tolerate unauthorized access to its customers’ information or company websites.   We will cooperate with law enforcement in any investigation of unauthorized system access and to prosecute violators to the fullest extent of the law. AT&T acted quickly to protect your information – and we promise to keep working around the clock to keep your information safe.  Thank you very much for your understanding, and for being an AT&T customer. Sincerely, Dorothy Attwood Senior Vice President, Public Policy and Chief Privacy Officer for AT&T Technorati Tags: AT&T,iPad 3G,Email

• Modernizr Rocks HTML5

  - by Laila

  HTML5 is a moving target.  At the moment, we don't know what will be in future versions.  In most circumstances, this really matters to the developer. When you're using Adobe Air, you can be reasonably sure what works, what is there, and what isn't, since you have a version of the browser built-in. With Metro, you can assume that you're going to be using at least IE 10.   If, however,  you are using HTML5 in a web application, then you are going to rely heavily on Feature Detection.  Feature-Detection is a collection of techniques that tell you, via JavaScript, whether the current browser has this feature natively implemented or not Feature Detection isn't just there for the esoteric stuff such as  Geo-location,  progress bars,  <canvas> support,  the new <input> types, Audio, Video, web workers or storage, but is required even for semantic markup, since old browsers make a pigs ear out of rendering this.  Feature detection can't rely just on reading the browser version and inferring from that what works. Instead, you must use JavaScript to check that an HTML5 feature is there before using it.  The problem with relying on the user-agent is that it takes a lot of historical data  to work out what version does what, and, anyway, the user-agent can be, and sometimes is, spoofed. The open-source library Modernizr  is just about the most essential  JavaScript library for anyone using HTML5, because it provides APIs to test for most of the CSS3 and HTML5 features before you use them, and is intelligent enough to alter semantic markup into 'legacy' 'markup  using shims  on page-load  for old browsers. It also allows you to check what video Codecs are installed for playing video. It also provides media queries  and conditional resource-loading (formerly YepNope.js.).  Generally, Modernizr gives you the choice of what you do about browsers that don't support the feature that you want. Often, the best choice is graceful degradation, but the resource-loading feature allows you to dynamically load JavaScript Shims to replace the standard API for missing or defective HTML5 functionality, called 'PolyFills'.  As the Modernizr site says 'Yes, not only can you use HTML5 today, but you can use it in the past, too!' The evolutionary progress of HTML5  requires a more defensive style of JavaScript programming where the programmer adopts a mindset of fearing the worst ( IE 6)  rather than assuming the best, whilst exploiting as many of the new HTML features as possible for the requirements of the site or HTML application.  Why would anyone want the distraction of developing their own techniques to do this when  Modernizr exists to do this for you?

• What Counts For a DBA: Replaceable

  - by Louis Davidson

  Replaceable is what every employee in every company instinctively strives not to be. Yet, if you’re an irreplaceable DBA, meaning that the company couldn’t find someone else who could do what you do, then you’re not doing a great job. A good DBA is replaceable. I imagine some of you are already reaching for the lighter fluid, about to set the comments section ablaze, but before you destroy a perfectly good Commodore 64, read on… Everyone is replaceable, ultimately. Anyone, anywhere, in any job, could be sitting at their desk reading this, blissfully unaware that this is to be their last day at work. Morbidly, you could be about to take your terminal breath. Ideally, it will be because another company suddenly offered you a truck full of money to take a new job, forcing you to bid a regretful farewell to your current employer (with barely a “so long suckers!” left wafting in the air as you zip out of the office like the Wile E Coyote wearing two pairs of rocket skates). I’ve often wondered what it would be like to be present at the meeting where your former work colleagues discuss your potential replacement. It is perhaps only at this point, as they struggle with the question “What kind of person do we need to replace old Wile?” that you would know your true worth in their eyes. Of course, this presupposes you need replacing. I’ve known one or two people whose absence we adequately compensated with a small rock, to keep their old chair from rolling down a slight incline in the floor. On another occasion, we bought a noise-making machine that frequently attracted attention its way, with unpleasant sounds, but never contributed anything worthwhile. These things never actually happened, of course, but you take my point: don’t confuse replaceable with expendable. Likewise, if the term “trained seal” comes up, someone they can teach to follow basic instructions and push buttons in the right order, then the replacement discussion is going to be over quickly. What, however, if your colleagues decide they’ll need a super-specialist to replace you. That’s a good thing, right? Well, usually, in my experience, no it is not. It often indicates that no one really knows what you do, or how. A typical example is the “senior” DBA who built a system just before 16-bit computing became all the rage and then settled into a long career managing it. Such systems are often central to the company’s operations and the DBA very skilled at what they do, but almost impossible to replace, because the system hasn’t evolved, and runs on processes and routines that others no longer understand or recognize. The only thing you really want to hear, at your replacement discussion, is that they need someone skilled at the fundamentals and adaptable. This means that the person they need understands that their goal is to be an excellent DBA, not a specialist in whatever the-heck the company does. Someone who understands the new versions of SQL Server and can adapt the company’s systems to the way things work today, who uses industry standard methods that any other qualified DBA/programmer can understand. More importantly, this person rarely wants to get “pigeon-holed” and so documents and shares the specialized knowledge and responsibilities with their teammates. Being replaceable doesn’t mean being “dime a dozen”. The company might need four people to take your place due to the depth of your skills, but still, they could find those replacements and those replacements could step right in using techniques that any decent DBA should know. It is a tough question to contemplate, but take some time to think about the sort of person that your colleagues would seek to replace you. If you think they would go looking for a “super-specialist” then consider urgently how you can diversify and share your knowledge, and start documenting all the processes you know as if today were your last day, because who knows, it just might be.

• 2D Tile Based Collision Detection

  - by MrPlosion1243

  There are a lot of topics about this and it seems each one addresses a different problem, this topic does the same. I was looking into tile collision detection and found this where David Gouveia explains a great way to get around the person's problem by separating the two axis. So I implemented the solution and it all worked perfectly from all the testes I through at it. Then I implemented more advanced platforming physics and the collision detection broke down. Unfortunately I have not been able to get it to work again which is where you guys come in :)! I will present the code first: public void Update(GameTime gameTime) { if(Input.GetKeyDown(Keys.A)) { velocity.X -= moveAcceleration; } else if(Input.GetKeyDown(Keys.D)) { velocity.X += moveAcceleration; } if(Input.GetKeyDown(Keys.Space)) { if((onGround && isPressable) || (!onGround && airTime <= maxAirTime && isPressable)) { onGround = false; airTime += (float)gameTime.ElapsedGameTime.TotalSeconds; velocity.Y = initialJumpVelocity * (1.0f - (float)Math.Pow(airTime / maxAirTime, Math.PI)); } } else if(Input.GetKeyReleased(Keys.Space)) { isPressable = false; } if(onGround) { velocity.X *= groundDrag; velocity.Y = 0.0f; } else { velocity.X *= airDrag; velocity.Y += gravityAcceleration; } velocity.Y = MathHelper.Clamp(velocity.Y, -maxFallSpeed, maxFallSpeed); velocity.X = MathHelper.Clamp(velocity.X, -maxMoveSpeed, maxMoveSpeed); position += velocity * (float)gameTime.ElapsedGameTime.TotalSeconds; position = new Vector2((float)Math.Round(position.X), (float)Math.Round(position.Y)); if(Math.Round(velocity.X) != 0.0f) { HandleCollisions2(Direction.Horizontal); } if(Math.Round(velocity.Y) != 0.0f) { HandleCollisions2(Direction.Vertical); } } private void HandleCollisions2(Direction direction) { int topTile = (int)Math.Floor((float)Bounds.Top / Tile.PixelTileSize); int bottomTile = (int)Math.Ceiling((float)Bounds.Bottom / Tile.PixelTileSize) - 1; int leftTile = (int)Math.Floor((float)Bounds.Left / Tile.PixelTileSize); int rightTile = (int)Math.Ceiling((float)Bounds.Right / Tile.PixelTileSize) - 1; for(int x = leftTile; x <= rightTile; x++) { for(int y = topTile; y <= bottomTile; y++) { Rectangle tileBounds = new Rectangle(x * Tile.PixelTileSize, y * Tile.PixelTileSize, Tile.PixelTileSize, Tile.PixelTileSize); Vector2 depth; if(Tile.IsSolid(x, y) && Intersects(tileBounds, direction, out depth)) { if(direction == Direction.Horizontal) { position.X += depth.X; } else { onGround = true; isPressable = true; airTime = 0.0f; position.Y += depth.Y; } } } } } From the code you can see when velocity.X is not equal to zero the HandleCollisions() Method is called along the horizontal axis and likewise for the vertical axis. When velocity.X is not equal to zero and velocity.Y is equal to zero it works fine. When velocity.Y is not equal to zero and velocity.X is equal to zero everything also works fine. However when both axis are not equal to zero that's when it doesn't work and I don't know why. I basically teleport to the left side of a tile when both axis are not equal to zero and there is a air block next to me. Hopefully someone can see the problem with this because I sure don't as far as I'm aware nothing has even changed from what I'm doing to what the linked post's solution is doing. Thanks.

• Platform jumping problems with AABB collisions

  - by Vee

  See the diagram first: When my AABB physics engine resolves an intersection, it does so by finding the axis where the penetration is smaller, then "push out" the entity on that axis. Considering the "jumping moving left" example: If velocityX is bigger than velocityY, AABB pushes the entity out on the Y axis, effectively stopping the jump (result: the player stops in mid-air). If velocityX is smaller than velocitY (not shown in diagram), the program works as intended, because AABB pushes the entity out on the X axis. How can I solve this problem? Source code: public void Update() { Position += Velocity; Velocity += World.Gravity; List<SSSPBody> toCheck = World.SpatialHash.GetNearbyItems(this); for (int i = 0; i < toCheck.Count; i++) { SSSPBody body = toCheck[i]; body.Test.Color = Color.White; if (body != this && body.Static) { float left = (body.CornerMin.X - CornerMax.X); float right = (body.CornerMax.X - CornerMin.X); float top = (body.CornerMin.Y - CornerMax.Y); float bottom = (body.CornerMax.Y - CornerMin.Y); if (SSSPUtils.AABBIsOverlapping(this, body)) { body.Test.Color = Color.Yellow; Vector2 overlapVector = SSSPUtils.AABBGetOverlapVector(left, right, top, bottom); Position += overlapVector; } if (SSSPUtils.AABBIsCollidingTop(this, body)) { if ((Position.X >= body.CornerMin.X && Position.X <= body.CornerMax.X) && (Position.Y + Height/2f == body.Position.Y - body.Height/2f)) { body.Test.Color = Color.Red; Velocity = new Vector2(Velocity.X, 0); } } } } } public static bool AABBIsOverlapping(SSSPBody mBody1, SSSPBody mBody2) { if(mBody1.CornerMax.X <= mBody2.CornerMin.X || mBody1.CornerMin.X >= mBody2.CornerMax.X) return false; if (mBody1.CornerMax.Y <= mBody2.CornerMin.Y || mBody1.CornerMin.Y >= mBody2.CornerMax.Y) return false; return true; } public static bool AABBIsColliding(SSSPBody mBody1, SSSPBody mBody2) { if (mBody1.CornerMax.X < mBody2.CornerMin.X || mBody1.CornerMin.X > mBody2.CornerMax.X) return false; if (mBody1.CornerMax.Y < mBody2.CornerMin.Y || mBody1.CornerMin.Y > mBody2.CornerMax.Y) return false; return true; } public static bool AABBIsCollidingTop(SSSPBody mBody1, SSSPBody mBody2) { if (mBody1.CornerMax.X < mBody2.CornerMin.X || mBody1.CornerMin.X > mBody2.CornerMax.X) return false; if (mBody1.CornerMax.Y < mBody2.CornerMin.Y || mBody1.CornerMin.Y > mBody2.CornerMax.Y) return false; if(mBody1.CornerMax.Y == mBody2.CornerMin.Y) return true; return false; } public static Vector2 AABBGetOverlapVector(float mLeft, float mRight, float mTop, float mBottom) { Vector2 result = new Vector2(0, 0); if ((mLeft > 0 || mRight < 0) || (mTop > 0 || mBottom < 0)) return result; if (Math.Abs(mLeft) < mRight) result.X = mLeft; else result.X = mRight; if (Math.Abs(mTop) < mBottom) result.Y = mTop; else result.Y = mBottom; if (Math.Abs(result.X) < Math.Abs(result.Y)) result.Y = 0; else result.X = 0; return result; }

• Type of computer for a developer on the road

  - by nabucosound

  Hi developers: I am planning to be traveling through eurasia and asia (russia, china, korea, japan, south east asia...) for a while and, although there are plenty of marvelous things to see and to do, I must keep on working :(. I am a python developer, dedicated mainly to web projects. I use django, sqlite3, browsers, and ocassionaly (only if I have no choice) I install postgres, mysql, apache or any other servers commonly used in the internets. I do my coding on vim, use ssh to connect, lftp to transfer files, IRC, grep/ack... So I spend most of my time in the terminal shells. But I also use IM or Skype to communicate with my clients and peers, as well as some other software (that after all is not mandatory for my day-to-day work). I currently work with a Macbook Pro (3 years old now) and so far I am very happy with the performance. But I don't want to carry it if I am going to be "on transit" for long time, it is simply huge and heavy for what I am planning to load in my rather small backpack (while traveling, less is more, you know). So here I am reading all kind of opinions about netbooks, because at first sight this is the kind of computer I thought I had to choose. I am going to use Linux for it, Microsoft is not my cup of tea and Mac is not available for them, unless I were to buy a Macbook air, something that I won't do because if I am robbed or rain/dust/truck loaders break it I would burst in tears. I am concerned about wifi performance and connectivity, I am going to use one of those linux distros/tools to hack/test on "open" networks (if you know what I mean) in case I am not in a place with real free wifi access and I find myself in an emergency. CPU speed should be acceptable, but since I don't plan to run Photoshop or expensive IDEs, I guess most of the time I won't be overloading the machine. Apart from this, maybe (surely) I am missing other features to consider. With that said (sorry about the length) here it comes my question, raised from a deep ignorance regarding the wars betweeb betbooks vs notebooks (I assume tablet PCs are not for programming yet): If I buy a netbook will I have to throw it away after 1 month on the road and buy a notebook? Or will I be OK? Thanks! Hector Update I have received great feedback so far! I would like to insist on the fact that I will be traveling through many different countries and scenarios. I am sure that while in Japan I will be more than fine with anything related to technology, connectivity, etc. But consider that I will be, for example, on a train through Russia (transsiberian) and will cross Mongolia as well. I will stay in friends' places sometimes, but most of the time I will have to work from hostel rooms, trains, buses, beaches (hey this last one doesn't sound too bad hehe!). I think some of your answers guys seem to focus on the geek part but loose the point of this "on the road" fact. I am very aware and agree that netbooks suck compared to notebooks, but what I am trying to do here is to find a balance and discover your experiences with netbooks to see first hand if a netbook will be a fail in the mid-long term of the trip for my purposes. So I have resumed the main concepts expressed here on this small list, in no particular order: keyboard/touchpad feel: I use vim so no need of moving mouse pointers that much, unless I am browsing the web, but intensive use of keyboard screen real state: again, terminal work for most of the time battery life: I think something very important weight/size: also very important looks not worth stealing it, don't give a shit if it is lost/stolen/broken: this may depend on kind of person, your economy, etc. Also to prevent losing work, I will upload EVERYTHING to the cloud whenever I'll have a chance. wifi: don't want to discover my wifi is one of those that cannot deal with half the routers on this planet or has poor connectivity. Thanks again for your answers and comments!

• Social Targeting: This One's Just for You

  - by Mike Stiles

  Think of social targeting in terms of the archery competition we just saw in the Olympics. If someone loaded up 5 arrows and shot them straight up into the air all at once, hoping some would land near the target, the world would have united in laughter. But sadly for hysterical YouTube video viewing, that’s not what happened. The archers sought to maximize every arrow by zeroing in on the spot that would bring them the most points. Marketers have always sought to do the same. But they can only work with the tools that are available. A firm grasp of the desired target does little good if the ad products aren’t there to deliver that target. On the social side, both Facebook and Twitter have taken steps to enhance targeting for marketers. And why not? As the demand to monetize only goes up, they’re quite motivated to leverage and deliver their incredible user bases in ways that make economic sense for advertisers. You could target keywords on Twitter with promoted accounts, and get promoted tweets into search. They would surface for your followers and some users that Twitter thought were like them. Now you can go beyond keywords and target Twitter users based on 350 interests in 25 categories. How does a user wind up in one of these categories? Twitter looks at that user’s tweets, they look at whom they follow, and they run data through some sort of Twitter secret sauce. The result is, you have a much clearer shot at Twitter users who are most likely to welcome and be responsive to your tweets. And beyond the 350 interests, you can also create custom segments that find users who resemble followers of whatever Twitter handle you give it. That means you can now use boring tweets to sell like a madman, right? Not quite. This ad product is still quality-based, meaning if you’re not putting out tweets that lead to interest and thus, engagement, that tweet will earn a low quality score and wind up costing you more under Twitter’s auction system to maintain. That means, as the old knight in “Indiana Jones and the Last Crusade” cautions, “choose wisely” when targeting based on these interests and categories to make sure your interests truly do line up with theirs. On the Facebook side, they’re rolling out ad targeting that uses email addresses, phone numbers, game and app developers’ user ID’s, and eventually addresses for you bigger brands. Why? Because you marketers asked for it. Here you were with this amazing customer list but no way to reach those same customers should they be on Facebook. Now you can find and communicate with customers you gathered outside of social, and use Facebook to do it. Fair to say such users are a sensible target and will be responsive to your message since they’ve already bought something from you. And no you’re not giving your customer info to Facebook. They’ll use something called “hashing” to make sure you don’t see Facebook user data (beyond email, phone number, address, or user ID), and Facebook can’t see your customer data. The end result, social becomes far more workable and more valuable to marketers when it delivers on the promise that made it so exciting in the first place. That promise is the ability to move past casting wide nets to the masses and toward concentrating marketing dollars efficiently on the targets most likely to yield results.

• The Three-Legged Milk Stool - Why Oracle Fusion Incentive Compensation makes the difference!

  - by Richard Lefebvre

  During the London Olympics, we were exposed to dozens of athletes who worked with sports psychologists to maximize their performance. Executives often hire business psychologists to coach their teams to excellence. In the same vein, Fusion Incentive Compensation can be used to get people to change their sales behavior so we can make our numbers. But what about using incentive compensation solutions in a non-sales scenario to drive change? Recently, I was working an opportunity where a company was having a low user adoption rate for Salesforce.com, which was causing problems for them. I suggested they use Fusion Incentive Comp to change the reps' behavior. We tossed around the idea of tracking user adoption by creating a variable bonus for reps based on how well they forecasted revenues in the new system. Another thought was to reward the reps for how often they logged into the system or for the percentage of leads that became opportunities and turned into revenue. A new twist on a great product. Fusion CRM's Sweet Spot I'm excited about the sales performance management (SPM) tools in Fusion CRM. This trio of Incentive Compensation, Territory Management, and Quota Management sets us apart from the competition because Oracle is the only vendor that provides all three of these capabilities on a single tech stack, in a single application, and with a single look and feel. The niche vendors offer standalone territory or incentive compensation solutions, but then the customer has to custom build the other tools and can end up with a Frankenstein-type environment. On average, companies overpay sales commissions by three to eight percent. You calculate that number for a company the size of Oracle for one quarter and it makes a pretty air-tight financial case for using SPM tools to figure accurate commissions. Plus when sales reps get the right compensation, they can be out selling rather than spending precious time figuring out what they didn't get paid or looking for another job. And one more thing ... Oracle knows incentive comp. We have been a Gartner Market Scope leader in this space for the last five years. Our solution gets high marks because of its scalability and because of its interoperability with other technologies. And now that we're leading with Fusion, our incentive compensation offering includes the innovations that the Fusion team built, plus enhancements from the E-Business Suite Incentive Comp team. It's a case of making a good thing even better. (See product video.) The "Wedge" Apps In a number of accounts that I'm working on, there is a non-Oracle CRM system of record. That gives me the perfect opportunity to introduce the benefits of our SPM tools and to get the customer using Fusion. Then the door is wide open for the company to uptake more of Fusion CRM, especially since all the integrations they need are out of the box. I really believe that implementing this wedge of SPM tools is the ticket to taking market share away from other vendors. It allows us to insert ourselves in an environment where no other CRM solution in the market has the extending capabilities of Fusion. Not Just Your Usual Suspects Usually the stakeholders that I talk to for Territory Management are tightly aligned with the sales management team. When I sell the quota planning tool, I'm talking to finance people on the ERP side of the house who are measuring quotas and forecasting revenue. And then Incentive Comp is of most interest to the sales operations people, and generally these people roll up to either HR or the payroll department. I think of our Fusion SPM tools as a three-legged stool straddling an organization's Sales, Finance, and HR departments. So when you're prospecting for opportunities -- yes, people with a CRM perspective will be very interested -- but don't limit yourselves to that constituency. You might find stakeholders in accounting, revenue planning, or HR compensation teams. You just might discover, as I did at United Airlines, that the HR organization is spearheading the CRM project because incentive compensation is what they need ... and they're the ones with the budget.

• Arcball Problems with UDK

  - by opdude

  I'm trying to re-create an arcball example from a Nehe, where an object can be rotated in a more realistic way while floating in the air (in my game the object is attached to the player at a distance like for example the Physics Gun) however I'm having trouble getting this to work with UDK. I have created an LGArcBall which follows the example from Nehe and I've compared outputs from this with the example code. I think where my problem lies is what I do to the Quaternion that is returned from the LGArcBall. Currently I am taking the returned Quaternion converting it to a rotation matrix. Getting the product of the last rotation (set when the object is first clicked) and then returning that into a Rotator and setting that to the objects rotation. If you could point me in the right direction that would be great, my code can be found below. class LGArcBall extends Object; var Quat StartRotation; var Vector StartVector; var float AdjustWidth, AdjustHeight, Epsilon; function SetBounds(float NewWidth, float NewHeight) { AdjustWidth = 1.0f / ((NewWidth - 1.0f) * 0.5f); AdjustHeight = 1.0f / ((NewHeight - 1.0f) * 0.5f); } function StartDrag(Vector2D startPoint, Quat rotation) { StartVector = MapToSphere(startPoint); } function Quat Update(Vector2D currentPoint) { local Vector currentVector, perp; local Quat newRot; //Map the new point to the sphere currentVector = MapToSphere(currentPoint); //Compute the vector perpendicular to the start and current perp = startVector cross currentVector; //Make sure our length is larger than Epsilon if (VSize(perp) > Epsilon) { //Return the perpendicular vector as the transform newRot.X = perp.X; newRot.Y = perp.Y; newRot.Z = perp.Z; //In the quaternion values, w is cosine (theta / 2), where //theta is the rotation angle newRot.W = startVector dot currentVector; } else { //The two vectors coincide, so return an identity transform newRot.X = 0.0f; newRot.Y = 0.0f; newRot.Z = 0.0f; newRot.W = 0.0f; } return newRot; } function Vector MapToSphere(Vector2D point) { local float x, y, length, norm; local Vector result; //Transform the mouse coords to [-1..1] //and inverse the Y coord x = (point.X * AdjustWidth) - 1.0f; y = 1.0f - (point.Y * AdjustHeight); length = (x * x) + (y * y); //If the point is mapped outside of the sphere //( length > radius squared) if (length > 1.0f) { norm = 1.0f / Sqrt(length); //Return the "normalized" vector, a point on the sphere result.X = x * norm; result.Y = y * norm; result.Z = 0.0f; } else //It's inside of the sphere { //Return a vector to the point mapped inside the sphere //sqrt(radius squared - length) result.X = x; result.Y = y; result.Z = Sqrt(1.0f - length); } return result; } DefaultProperties { Epsilon = 0.000001f } I'm then attempting to rotate that object when the mouse is dragged, with the following update code in my PlayerController. //Get Mouse Position MousePosition.X = LGMouseInterfacePlayerInput(PlayerInput).MousePosition.X; MousePosition.Y = LGMouseInterfacePlayerInput(PlayerInput).MousePosition.Y; newQuat = ArcBall.Update(MousePosition); rotMatrix = MakeRotationMatrix(QuatToRotator(newQuat)); rotMatrix = rotMatrix * LastRot; LGMoveableActor(movingPawn.CurrentUseableObject).SetPhysics(EPhysics.PHYS_Rotating); LGMoveableActor(movingPawn.CurrentUseableObject).SetRotation(MatrixGetRotator(rotMatrix));

• Libgdx 2D Game, Random generated World of random size, how to get mouse coordinates?

  - by Solom

  I'm a noob and English is not my mothertongue, so please bear with me! I'm generating a map for a Sidescroller out of a 2D-array. That is, the array holds different values and I create blocks based on that value. Now, my problem is to match mouse coordinates on screen with the actual block the mouse is pointing at. public class GameScreen implements Screen { private static final int WIDTH = 100; private static final int HEIGHT = 70; private OrthographicCamera camera; private Rectangle glViewport; private Spritebatch spriteBatch; private Map map; private Block block; ... @Override public void show() { camera = new OrthographicCamera(WIDTH, HEIGHT); camera.position.set(WIDTH/2, HEIGHT/2, 0); glViewport = new Rectangle(0, 0, WIDTH, HEIGHT); map = new Map(16384, 256); map.printTileMap(); // Debugging only spriteBatch = new SpriteBatch(); } @Override public void render(float delta) { // Clear previous frame Gdx.gl.glClearColor(1, 1, 1, 1 ); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); GL30 gl = Gdx.graphics.getGL30(); // gl.glViewport((int) glViewport.x, (int) glViewport.y, (int) glViewport.width, (int) glViewport.height); spriteBatch.setProjectionMatrix(camera.combined); camera.update(); spriteBatch.begin(); // Draw Map this.drawMap(); // spriteBatch.flush(); spriteBatch.end(); } private void drawMap() { for(int a = 0; a < map.getHeight(); a++) { // Bounds check (y) if(camera.position.y + camera.viewportHeight < a)// || camera.position.y - camera.viewportHeight > a) break; for(int b = 0; b < map.getWidth(); b++) { // Bounds check (x) if(camera.position.x + camera.viewportWidth < b)// || camera.position.x > b) break; // Dynamic rendering via BlockManager int id = map.getTileMap()[a][b]; Block block = BlockManager.map.get(id); if(block != null) // Check if Air { block.setPosition(b, a); spriteBatch.draw(block.getTexture(), b, a, 1 ,1); } } } } As you can see, I don't use the viewport anywhere. Not sure if I need it somewhere down the road. So, the map is 16384 blocks wide. One block is 16 pixels in size. One of my naive approaches was this: if(Gdx.input.isButtonPressed(Input.Buttons.LEFT)) { Vector3 mousePos = new Vector3(); mousePos.set(Gdx.input.getX(), Gdx.input.getY(), 0); camera.unproject(mousePos); System.out.println(Math.round(mousePos.x)); // *16); // Debugging // TODO: round // map.getTileMap()[mousePos.x][mousePos.y] = 2; // Draw at mouse position } I confused myself somewhere down the road I fear. What I want to do is, update the "block" (or rather the information in the Map/2D-Array) so that in the next render() there is another block. Basically drawing on the spriteBatch g So if anyone could point me in the right direction this would be highly appreciated. Thanks!

• Test your internet connection - Emtel Fixed Broadband

  Already at the begin of April, I had a phone conversation with my representative at Emtel Ltd. about some upcoming issues due to the ongoing construction work in my neighbourhood. Unfortunately, they finally raised the house two levels above ours, and of course this has to have a negative impact on the visibility between the WiMAX outdoor unit on the roof and the aimed access point at Medine. So, today I had a technical team here to do a site survey and to come up with potential solutions. Short version: It doesn't look good after all. The site survey Well, the two technicians did their work properly, even re-arranged the antenna to check the connection with another end point down at La Preneuse. But no improvements. Looks like we are out of luck since the construction next door hasn't finished yet and at the moment, it even looks like they are planning to put at least one more level on top. I really wonder about the sanity of the responsible bodies at the local district council. But that's another story. Anyway, the outdoor unit was once again pointed towards Medine and properly fixed with new cable guides (air from the sea and rust...). Both of them did a good job and fine-tuned the reception signal to a mere 3 over 9; compared to the original 7 over 9 I had before the daily terror started. The site survey has been done, and now it's up to Emtel to come up with (better) solutions. Well, I wouldn't mind to have an unlimited, symmetric 3G/UMTS or even LTE connection. Let's see what they can do... Testing the connection There are several online sites available which offer you to check certain aspects of your internet connection. Personally, I'm used to speedtest.net and it works very well. I think it is good and necessary to check your connection from time to time, and only a couple of days ago, I posted the following on Emtel's wall at Facebook (21.05.2013 - 14:06 hrs): Dear Emtel, could you eventually provide an answer on the miserable results of SpeedTest? I chose Rose Hill (Hosted by Emtel Ltd.) as testing endpoint... Sadly, no response to this. Seems that the marketing department is not willing to deal with customers on Facebook. Okay, over at speedtest.net you can use their Flash-based test suite to check your connection to quite a number of servers of different providers world-wide. It's actually very interesting to see the results for different end points and to compare them to each other. The results Following are the results of Rose Hill (hosted by Emtel) and respectively Frankfurt, Germany (hosted by Vodafone DE): Speedtest.net result of 30.05.2013 between Flic en Flac and Rose Hill, Mauritius (Emtel - Fixed Broadband) Speedtest.net result of 30.05.2013 between Flic en Flac and Frankfurt, Germany (Emtel - Fixed Broadband) Luckily, the results are quite similar in terms of connection speed; which is good. I'm currently on a WiMAX tariff called 'Classic Browsing 2', or Fixed Broadband as they call it now, which provides a symmetric line of 768 Kbps (or roughly 0.75 Mbps). In terms of downloads or uploads this means that I would be able to transfer files in either direction with approximately 96 KB/s. Frankly speaking, thanks to compression, my choice of browser and operating system I usually exceed this value and I have download rates up to 120 KB/s - not too bad after all. Only the ping times are a little bit of concern. Due to the difference in distance, or better said based on the number of hubs between the endpoints, they indicate the amount of time that it takes to send a package from your machine to the remote server and get a response back. A lower value is better, and usually the ping is less than 300 ms between Mauritius and Europe. The alternatives in Mauritius Not sure whether I should note this done because for my requirements there are no alternatives to Emtel WiMAX at the moment. It would be great to have your opinion on the situation of internet connectivity in Mauritius. Are there really alternatives? And if so, what are the conditions?

• Modernizr Rocks HTML5

  - by Laila

  HTML5 is a moving target.  At the moment, we don't know what will be in future versions.  In most circumstances, this really matters to the developer. When you're using Adobe Air, you can be reasonably sure what works, what is there, and what isn't, since you have a version of the browser built-in. With Metro, you can assume that you're going to be using at least IE 10.   If, however,  you are using HTML5 in a web application, then you are going to rely heavily on Feature Detection.  Feature-Detection is a collection of techniques that tell you, via JavaScript, whether the current browser has this feature natively implemented or not Feature Detection isn't just there for the esoteric stuff such as  Geo-location,  progress bars,  <canvas> support,  the new <input> types, Audio, Video, web workers or storage, but is required even for semantic markup, since old browsers make a pigs ear out of rendering this.  Feature detection can't rely just on reading the browser version and inferring from that what works. Instead, you must use JavaScript to check that an HTML5 feature is there before using it.  The problem with relying on the user-agent is that it takes a lot of historical data  to work out what version does what, and, anyway, the user-agent can be, and sometimes is, spoofed. The open-source library Modernizr  is just about the most essential  JavaScript library for anyone using HTML5, because it provides APIs to test for most of the CSS3 and HTML5 features before you use them, and is intelligent enough to alter semantic markup into 'legacy' 'markup  using shims  on page-load  for old browsers. It also allows you to check what video Codecs are installed for playing video. It also provides media queries  and conditional resource-loading (formerly YepNope.js.).  Generally, Modernizr gives you the choice of what you do about browsers that don't support the feature that you want. Often, the best choice is graceful degradation, but the resource-loading feature allows you to dynamically load JavaScript Shims to replace the standard API for missing or defective HTML5 functionality, called 'PolyFills'.  As the Modernizr site says 'Yes, not only can you use HTML5 today, but you can use it in the past, too!' The evolutionary progress of HTML5  requires a more defensive style of JavaScript programming where the programmer adopts a mindset of fearing the worst ( IE 6)  rather than assuming the best, whilst exploiting as many of the new HTML features as possible for the requirements of the site or HTML application.  Why would anyone want the distraction of developing their own techniques to do this when  Modernizr exists to do this for you?

• How to make a stack stable? Need help for an explicit resting contact scheme (2-dimensional)

  - by Register Sole

  Previously, I struggle with the sequential impulse-based method I developed. Thanks to jedediah referring me to this paper, I managed to rebuild the codes and implement the simultaneous impulse based method with Projected-Gauss-Seidel (PGS) iterative solver as described by Erin Catto (mentioned in the reference of the paper as [Catt05]). So here's how it currently is: The simulation handles 2-dimensional rotating convex polygons. Detection is using separating-axis test, with a SKIN, meaning closest points between two polygons is detected and determined if their distance is less than SKIN. To resolve collision, simultaneous impulse-based method is used. It is solved using iterative solver (PGS-solver) as in Erin Catto's paper. Error-correction is implemented using Baumgarte's stabilization (you can refer to either paper for this) using J V = beta/dt*overlap, J is the Jacobian for the constraints, V the matrix containing the velocities of the bodies, beta an error-correction parameter that is better be < 1, dt the time-step taken by the engine, and overlap, the overlap between the bodies (true overlap, so SKIN is ignored). However, it is still less stable than I expected :s I tried to stack hexagons (or squares, doesn't really matter), and even with only 4 to 5 of them, they would swing! Also note that I am not looking for a sleeping scheme. But I would settle if you have any explicit scheme to handle resting contacts. That said, I would be more than happy if you have a way of treating it generally (as continuous collision, instead of explicitly as a special state). Ideas I have tried: Using simultaneous position based error correction as described in the paper in section 5.3.2, turned out to be worse than the current scheme. If you want to know the parameters I used: Hexagons, side 50 (pixels) gravity 2400 (pixels/sec^2) time-step 1/60 (sec) beta 0.1 restitution 0 to 0.2 coeff. of friction 0.2 PGS iteration 10 initial separation 10 (pixels) mass 1 (unit is irrelevant for now, i modified velocity directly<-impulse method) inertia 1/1000 Thanks in advance! I really appreciate any help from you guys!! :) EDIT In response to Cholesky's comment about warm starting the solver and Baumgarte: Oh right, I forgot to mention! I do save the contact history and the impulse determined in this time step to be used as initial guess in the next time step. As for the Baumgarte, here's what actually happens in the code. Collision is detected when the bodies' closest distance is less than SKIN, meaning they are actually still separated. If at this moment, I used the PGS solver without Baumgarte, restitution of 0 alone would be able to stop the bodies, separated by a distance of ~SKIN, in mid-air! So this isn't right, I want to have the bodies touching each other. So I turn on the Baumgarte, where its role is actually to pull the bodies together! Weird I know, a scheme intended to push the body apart becomes useful for the reverse. Also, I found that if I increase the number of iteration to 100, stacks become much more stable, though the program becomes so slow. UPDATE Since the stack swings left and right, could it be something is wrong with my friction model? Current friction constraint: relative_tangential_velocity = 0

• The new direction of the gaming industry

  - by raccoon_tim

  Just recently I read a great blog post by David Darling, the founder of Codemasters: http://www.develop-online.net/blog/347/Jurassic-consoles-could-become-extinct. In the blog post he talks about how traditional retail games are experiencing a downfall thanks to the increasing popularity of digital distribution. I personally think of retail games as being relics of the past. It does not really make much sense to still keep distributing boxed games when the same game can be elegantly downloaded and updated over the air through a digital distribution channel. The world is not all rainbows, however. One big issue with mixing digital distribution with boxed retail games is that resellers will not condone you selling your game for 10€ digitally while their selling the same game for 70€. The only way to get around this issue is to move to full digital distribution. This has the added benefit of minimizing piracy as the game can be tightly bound to the service you downloaded the game from. Many players are, however, complaining about not being able to play the games offline. Having games tightly bound to the internet is a problem when games are bought from a retailer as we tend to expect that once we have the product we can use it anywhere because we physically own it. The truth is that we don’t actually own the product. Instead, the typical EULA actually states that we only have a license to use the product. We’re not, for instance, allowed to disassemble the product, which the owner is indeed permitted to do. Digital distribution allows us to provide games as services, instead of selling them as standalone products. This means that for a service to work you have to be connected to the internet but you still have the same rights to use the product. It’s really straightforward; if you downloaded a client from the internet you are expected to have an internet connection so you’re able to connect to the server. A game distributed digitally that is built using a client-server architecture has the added benefit of allowing you to play anywhere as long as you have the client installed and you are able to log in with your user information. Your save games can be backed up and your game can continue anywhere. Another development we’re seeing in the gaming industry is the increasing popularity of free-to-play games. These are games that let you play for free but allow you to boost your gaming experience with real world money. The nature of these games is that players are constantly rewarded with new content and the game can evolve according to their way of playing and their wishes can be incorporated into the product. Free-to-play games can quickly gain a large player basis and monetization is done by providing players valuable things to buy making their gaming experience more fun. I am personally very excited about free-to-play games as it’s possible to start building the game together with your players and there is no need to work on the game for 5 years from start to finish and only then see if it’s actually something the players like. This is a typical problem with big movie-like retail games and recent news about Radical Entertainment practically closing its doors paints a clear picture of what can happen when the risk does not pay off: http://news.teamxbox.com/xbox/25874/Prototype-Developer-Radical-Entertainment-Closes/.

• Using PHP substr() and strip_tags() while retaining formatting and without breaking HTML

  - by Peter

  I have various HTML strings to cut to 100 characters (of the stripped content, not the original) without stripping tags and without breaking HTML. Original HTML string (288 characters): $content = "<div>With a <span class='spanClass'>span over here</span> and a <div class='divClass'>nested div over <div class='nestedDivClass'>there</div> </div> and a lot of other nested <strong><em>texts</em> and tags in the air <span>everywhere</span>, it's a HTML taggy kind of day.</strong></div>"; When trimming to 100 characters HTML breaks and stripped content comes to about 40 characters: $content = substr($content, 0, 100)."..."; /* output: <div>With a <span class='spanClass'>span over here</span> and a <div class='divClass'>nested div ove... */ Stripping HTML gives the correct character count but obviously looses formatting: $content = substr(strip_tags($content)), 0, 100)."..."; /* output: With a span over here and a nested div over there and a lot of other nested texts and tags in the ai... */ Challenge: To output the character count of strip_tags while retaining HTML formatting and on closing the string finish any started tags: /* <div>With a <span class='spanClass'>span over here</span> and a <div class='divClass'>nested div over <div class='nestedDivClass'>there</div> </div> and a lot of other nested <strong><em>texts</em> and tags in the ai</strong></div>..."; Similar question (less strict on solution provided so far)

• How to write a decent process filter?

  - by konr

  Hi there, I'm building a program that communicates with Emacs, and one of the challenges I'm facing is writing Emacs's process filter function. Its input string is a series of s-expressions to be evaluated. Here is a sample: (gimme-append-to-buffer "25 - William Christie dir, Les Arts Florissants - Scene 2. Prelude - Les Arts Florissants\n") (gimme-append-to-buffer "26 - William Christie dir, Les Arts Florissants - Cybele: 'Je Veux Joindre' - Les Arts Florissants\n") (gimme-append-to-buffer "27 - William Christie dir, Les Arts Florissants - Scene 3. Cybele: 'Tu T'Etonnes, Melisse' - Les Arts Florissants\n") (gimme-append-to-buffer "28 - William Christie dir, Les Arts Florissants - Cybele: 'Que Les Plus Doux Zephyrs'. Scene 4. - Les Arts Florissants\n") (gimme-append-to-buffer "29 - William Christie dir, Les Arts Florissants - Entree Des Nations - Les Arts Florissants\n") (gimme-append-to-buffer "30 - William Christie dir, Les Arts Florissants - Entree Des Zephyrs - Les Arts Florissants\n") (gimme-append-to-buffer "31 - William Christie dir, Les Arts Florissants - Choeur Des Nations' 'Que Devant Vous' - Les Arts Florissants\n") (gimme-append-to-buffer "32 - William Christie dir, Les Arts Florissants - Atys: 'Indigne Que Je Suis' - Les Arts Florissants\n") (gimme-append-to-buffer "33 - William Christie dir, Les Arts Florissants - Reprise Du Choeur Des Nations : 'Que Devant Nous' - Les Arts Florissants\n") (gimme-append-to-buffer "34 - William Christie dir, Les Arts Flor*emphasized text*issants - Reprise De L'Air Des Zephyrs - Les Arts Florissants\n") The first problem that I've faced is that the string is somehow not fully formed when the function is so called, so writing something like (mapcar 'eval (format "(%s)" input-string)) won't work. To deal with this first problem, I was using a loop. The full function I wrote is: (defun eval-all-sexps (s) (loop for x = (ignore-errors (read-from-string s)) then (ignore-errors (read-from-string (substring s position))) while x summing (or (cdr x) 0) into position doing (eval (car x)))) Now the second problem that showed up is that the function is called twice with a somewhat large input, first with valid but partial content, then with what looks like pieces of the remaining data. To solve this problem, I'm considering using a junk variable to hold up what remains from a loop and then concatenating it to the input of the next call, but I was wondering if you guys have any other suggestions on how to deal with such a problem more elegantly. Thanks!

• Flex - Flash Builder Design View not showing embedded fonts correctly

  - by Crusader

  Tools: Air 2, Flex SDK 4.1, Flash Builder, Halo component set (NO Spark being used at all) Fonts work perfectly when running the appliction, but not in design view. This effectively makes design view WORTHLESS because it's impossible to properly position components or labels without knowing what the true size is (it changes depending on font...) ... CSS included in root component like so: <fx:Style source="style.css"/> CSS file: /* CSS file */ @namespace mx "library://ns.adobe.com/flex/mx"; global { font-family:Segoe; font-size:14; color:#FFFFFF; } mx|Application, mx|VBox, mx|HBox, mx|Canvas { font-family:Segoe; background-color:#660000; border-color:#222277; color:#FFFFFF; } mx|Button { font-family:Segoe; fill-colors:#660000, #660000, #660000, #660000; color:#FFFFFF; } .... Interestingly (or buggily?), when I try pasting the style tag into a subcomponent (lower than the top level container), I get a bunch of warnings in the subcomponent editor view stating that CSS type selectors are not supported in.. (all the components in the style sheet). Yet, they do work when the application is executed. Huh? This is how I'm embedding the fonts in the root level container: [Embed(source="/assets/segoepr.ttf", fontName="Segoe", mimeType="application/x-font-truetype", embedAsCFF='false')] public static const font:Class; [Embed(source="/assets/segoeprb.ttf", fontName="Segoe", mimeType="application/x-font-truetype", fontWeight="bold", embedAsCFF='false')] public static const font2:Class; So, is there a way to get embedded fonts to work in design view or what?

• as3crypto PEM.readRSAPublicKey returns null

  - by www.jefferyfernandez.id.au

  I am trying to implement a bit of encryption in my Air application while communication with a PHP backend server. For this purpose I am using as3crypto library and I can't read the public key to make the encryption possible. Here is my action script code: var rsa:RSAKey = PEM.readRSAPublicKey(this.readApplicationFileContents('server.crt')); if ( rsa ) { var encodeSource:ByteArray = Hex.toArray(Hex.fromString("Hello World")); var encodeDestination:ByteArray = new ByteArray; var encodeDestination2:ByteArray = new ByteArray; rsa.encrypt(encodeSource, encodeDestination, encodeSource.length) rsa.decrypt(encodeDestination, encodeDestination2, encodeDestination.length); trace(encodeDestination2.toString()); } private function readApplicationFileContents(filePath:String):String { var fileObject:File = File.applicationDirectory.resolvePath(filePath); var fileStream:FileStream = new FileStream(); fileStream.open(fileObject, FileMode.READ); var fileContents:String = fileStream.readUTFBytes(fileStream.bytesAvailable); return(fileContents); } readApplicationFileContents function returns the proper certificate contents as a string. But rsa variable always returns null. It would have been easier if I was able to compile the as3crypto library so I can debug through the source, but I can't get the library to compile and can't find any instructions to do the same. Anyone have a clue what's wrong? PS. Sorry first time poster and I can't seem to get the syntax highlighting right. Must be Chrome is not working well with the editor.

• Application icons for Flex mobile app targeting Android and iOS

  The Adobe doc Developing AIR applications for mobile devices lists quite a few icons to be declared in an application descriptor file. But when I try Export Release Build with the following myApp-app.xml: <icon> <image16x16>assets/icons/16x16.png</image16x16> <image29x29>assets/icons/29x29.png</image29x29> <image32x32>assets/icons/32x32.png</image32x32> <image36x36>assets/icons/36x36.png</image36x36> <image48x48>assets/icons/48x48.png</image48x48> <image57x57>assets/icons/57x57.png</image57x57> <image72x72>assets/icons/72x72.png</image72x72> <image114x114>assets/icons/114x114.png</image114x114> <image128x128>assets/icons/128x128.png</image128x128> <image512x512>assets/icons/512x512.png</image512x512> <!-- <image50x50>assets/icons/50x50.png</image50x50> <image58x58>assets/icons/58x58.png</image58x58> <image100x100>assets/icons/100x100.png</image100x100> <image144x144>assets/icons/144x144.png</image144x144> <image1024x1024>assets/icons/1024x1024.png</image1024x1024> --> </icon> I get the error message (regardless if deploying for Android or iOS) unless I comment the 5 lines as above: error 103: application.icon.image50x50 is an unexpected element/attribute error 103: application.icon.image58x58 is an unexpected element/attribute error 103: application.icon.image100x100 is an unexpected element/attribute error 103: application.icon.image1024x1024 is an unexpected element/attribute error 103: application.icon.image144x144 is an unexpected element/attribute My question is what to do here? Moving those 5 icons underneath <android>....</android> or <iphone>....</iphone> doesn't help either. Using Flash Builder 4.7 beta under Windows 7 / 64 bit.

• Actionscript image download open custom viewer

  - by Vish

  Hi Gurus, i am downloading tiff images from WAMP server using our Flex AIR client. Using the following code for that. public static function requestDownload(id:int, defaultName:String):void { //POST params var urlVars:URLVariables = new URLVariables(); urlVars.action = "download"; urlVars.fid = id; var urlReq:URLRequest = new URLRequest(); urlReq.url = Config.getServerURL(); urlReq.data = urlVars; Config.fileReference.addEventListener(Event.,FileDownload.requestDownloadResultV); try { Config.fileReference.download(urlReq, defaultName); } catch (e:Error) { Alert.show("Error in downloading the file"); } } public static function requestDownloadResultV(e:Event):void { Alert.show("File downloaded"); } No issues with the download. It automatically prompts for a Save dialog. Works well. But i want to open the image being downloaded in a viewer(flash viewer or any) instead of the save dialog. Please help me. Thanks Vish.

• Designing secure consumer blackberry application

  - by Kiran Kuppa

  I am evaluating a requirement for a consumer blackberry application that places high premium on security of user's data. Seems like it is an insurance company. Here are my ideas on how I could go about it. I am sure this would be useful for others who are looking for similar stuff Force the user to use device password. (I am guessing that this would be possible - though not checked it yet). Application can request notifications when the device is about to be locked and just after it has been unlocked. Encryption of application specific data can be managed at those times. Application data would be encrypted with user's password. User's credentials would be encrypted with device password. Remote backup of the data could be done over HTTPS (any better ideas are appreciated) Questions: What if the user forgets his device password. If the user forgets his application password, what is the best and secure way to reset the password? If the user losses the phone, remote backup must be done and the application data must be cleaned up. I have some ideas on how to achieve (3) and shall share them. There must be an off-line verification of the user's identity and the administrator must provide a channel using which the user must be able to send command to the device to perform the wiping of application data. The idea is that the user is ALWAYS in control of his data. Without the user's consent, even the admin must not be able to do activities such as cleaning up the data. In the above scheme of things, it appears as if the user's password need not be sent over the air to server. Am I correct? Thanks, --Kiran Kumar

• Why does a conditional not affect query speed?

  - by Telos

  I have a stored procedure that was taking a "long" period of time to execute. The query only needs to return data in one case, so I figured I could check for that case and just return before hitting the actual query. The only problem is that it still takes the same amount of time to execute with an if statement. I have verified that the code inside the if is not executing, and that if I replace the complex query with a simple select the speed is fine... so now I'm confused. Why is the query being slowed down by code that doesn't get executed when the conditional is false? Here's the query itself: ALTER PROCEDURE [dbo].[pr_cbc_GetCokeInfo] @pa_record int, @pb_record int AS BEGIN SET NOCOUNT ON; declare @ticketRec int SELECT @ticketRec = TicketRecord FROM eservice_live..v_sdticket where TicketRecord=@pa_record AND serviceCompanyID = 1139 AND @pb_record IS NULL if @ticketRec IS NULL return select record = null, doc_ref = @pa_record, memo_type = 'I', memo = 'Bottler: ' + isnull(Bottler, '') + ' ' + 'Sales Loc: ' + isnull(SalesLocation, '') + ' ' + 'Outlet Desc: ' + isnull(OutletDesc, '') + ' ' + 'City: ' + isnull(OutletCity, '') + ' ' + 'EquipNo: ' + isnull(EquipNo, '') + ' ' + 'SerialNo: ' + isnull(SerialNo, '') + ' ' + 'PhaseNo: ' + isnull(cast(PhaseNo as varchar(255)), '') + ' ' + 'StaticIP: ' + isnull(StaticIP, '') + ' ' + 'Air Card: ' + isnull(AirCard, '') FROM eservice_live..v_SDExtendedInfoField ef JOIN eservice_live..CokeSNList csl ON ef.valueText=csl.SerialNo where ef.docType='CLH' AND ef.docref = @ticketRec AND ef.ExtendedDocNumber=5 SET NOCOUNT OFF; END

  im trying out paypals html api where you specify price, item_name, customer information and so on in the html: <form action="https://www.paypal.com/cgi-bin/webscr" method="post" id="payPalForm"> <input type="hidden" name="cmd" value="_cart" /> <input type="hidden" name="upload" value="1" /> <input type="hidden" name="no_note" value="1" /> <input type="hidden" name="business" value="[email protected]" /> <input type="hidden" name="currency_code" value="SEK" /> <input type="hidden" name="return" value="http://freelanceswitch.com/payment-complete/" /> <input type="hidden" name="tax_rate" value="25" /> <input type="hidden" name="item_name_1" value="Apple Macpro" /> <input type="hidden" name="item_number_1" value="01 - Product 1" /> <input type="hidden" name="amount_1" value="25000" /> <input type="hidden" name="item_name_2" value="Apple Macbook" /> <input type="hidden" name="item_number_2" value="02 - Product 2" /> <input type="hidden" name="amount_2" value="12500" /> <input type="hidden" name="item_name_3" value="Apple Macbook Air" /> <input type="hidden" name="item_number_3" value="03 - Product 3" /> <input type="hidden" name="amount_3" value="12500" /> <input type="submit" name="Submit" value="Submit" /> </form> when the user clicks submit it takes him/her to paypals payment page. but doesn't this mean that a hacker could change the order by manipulating the html code? i can´t figure out how paypal prevents this security problem.
