• SPARC T4-4 Delivers World Record Performance on Oracle OLAP Perf Version 2 Benchmark

  - by Brian

  Oracle's SPARC T4-4 server delivered world record performance with subsecond response time on the Oracle OLAP Perf Version 2 benchmark using Oracle Database 11g Release 2 running on Oracle Solaris 11. The SPARC T4-4 server achieved throughput of 430,000 cube-queries/hour with an average response time of 0.85 seconds and the median response time of 0.43 seconds. This was achieved by using only 60% of the available CPU resources leaving plenty of headroom for future growth. The SPARC T4-4 server operated on an Oracle OLAP cube with a 4 billion row fact table of sales data containing 4 dimensions. This represents as many as 90 quintillion aggregate rows (90 followed by 18 zeros). Performance Landscape Oracle OLAP Perf Version 2 Benchmark 4 Billion Fact Table Rows System Queries/hour Users* Response Time (sec) Average Median SPARC T4-4 430,000 7,300 0.85 0.43 * Users - the supported number of users with a given think time of 60 seconds Configuration Summary and Results Hardware Configuration: SPARC T4-4 server with 4 x SPARC T4 processors, 3.0 GHz 1 TB memory Data Storage 1 x Sun Fire X4275 (using COMSTAR) 2 x Sun Storage F5100 Flash Array (each with 80 FMODs) Redo Storage 1 x Sun Fire X4275 (using COMSTAR with 8 HDD) Software Configuration: Oracle Solaris 11 11/11 Oracle Database 11g Release 2 (11.2.0.3) with Oracle OLAP option Benchmark Description The Oracle OLAP Perf Version 2 benchmark is a workload designed to demonstrate and stress the Oracle OLAP product's core features of fast query, fast update, and rich calculations on a multi-dimensional model to support enhanced Data Warehousing. The bulk of the benchmark entails running a number of concurrent users, each issuing typical multidimensional queries against an Oracle OLAP cube consisting of a number of years of sales data with fully pre-computed aggregations. The cube has four dimensions: time, product, customer, and channel. Each query user issues approximately 150 different queries. One query chain may ask for total sales in a particular region (e.g South America) for a particular time period (e.g. Q4 of 2010) followed by additional queries which drill down into sales for individual countries (e.g. Chile, Peru, etc.) with further queries drilling down into individual stores, etc. Another query chain may ask for yearly comparisons of total sales for some product category (e.g. major household appliances) and then issue further queries drilling down into particular products (e.g. refrigerators, stoves. etc.), particular regions, particular customers, etc. Results from version 2 of the benchmark are not comparable with version 1. The primary difference is the type of queries along with the query mix. Key Points and Best Practices Since typical BI users are often likely to issue similar queries, with different constants in the where clauses, setting the init.ora prameter "cursor_sharing" to "force" will provide for additional query throughput and a larger number of potential users. Except for this setting, together with making full use of available memory, out of the box performance for the OLAP Perf workload should provide results similar to what is reported here. For a given number of query users with zero think time, the main measured metrics are the average query response time, the median query response time, and the query throughput. A derived metric is the maximum number of users the system can support achieving the measured response time assuming some non-zero think time. The calculation of the maximum number of users follows from the well-known response-time law N = (rt + tt) * tp where rt is the average response time, tt is the think time and tp is the measured throughput. Setting tt to 60 seconds, rt to 0.85 seconds and tp to 119.44 queries/sec (430,000 queries/hour), the above formula shows that the T4-4 server will support 7,300 concurrent users with a think time of 60 seconds and an average response time of 0.85 seconds.

• Scripting custom drawing in Delphi application with IF/THEN/ELSE statements?

  - by Jerry Dodge

  I'm building a Delphi application which displays a blueprint of a building, including doors, windows, wiring, lighting, outlets, switches, etc. I have implemented a very lightweight script of my own to call drawing commands to the canvas, which is loaded from a database. For example, one command is ELP 1110,1110,1290,1290,3,8388608 which draws an ellipse, parameters are 1110x1110 to 1290x1290 with pen width of 3 and the color 8388608 converted from an integer to a TColor. What I'm now doing is implementing objects with common drawing routines, and I'd like to use my scripting engine, but this calls for IF/THEN/ELSE statements and such. For example, when I'm drawing a light, if the light is turned on, I'd like to draw it yellow, but if it's off, I'd like to draw it gray. My current scripting engine has no recognition of such statements. It just accepts simple drawing commands which correspond with TCanvas methods. Here's the procedure I've developed (incomplete) for executing a drawing command on a canvas: function DrawCommand(const Cmd: String; var Canvas: TCanvas): Boolean; type TSingleArray = array of Single; var Br: TBrush; Pn: TPen; X: Integer; P: Integer; L: String; Inst: String; T: String; Nums: TSingleArray; begin Result:= False; Br:= Canvas.Brush; Pn:= Canvas.Pen; if Assigned(Canvas) then begin if Length(Cmd) > 5 then begin L:= UpperCase(Cmd); if Pos(' ', L)> 0 then begin Inst:= Copy(L, 1, Pos(' ', L) - 1); Delete(L, 1, Pos(' ', L)); L:= L + ','; SetLength(Nums, 0); X:= 0; while Pos(',', L) > 0 do begin P:= Pos(',', L); T:= Copy(L, 1, P - 1); Delete(L, 1, P); SetLength(Nums, X + 1); Nums[X]:= StrToFloatDef(T, 0); Inc(X); end; Br.Style:= bsClear; Pn.Style:= psSolid; Pn.Color:= clBlack; if Inst = 'LIN' then begin Pn.Width:= Trunc(Nums[4]); if Length(Nums) > 5 then begin Br.Style:= bsSolid; Br.Color:= Trunc(Nums[5]); end; Canvas.MoveTo(Trunc(Nums[0]), Trunc(Nums[1])); Canvas.LineTo(Trunc(Nums[2]), Trunc(Nums[3])); Result:= True; end else if Inst = 'ELP' then begin Pn.Width:= Trunc(Nums[4]); if Length(Nums) > 5 then begin Br.Style:= bsSolid; Br.Color:= Trunc(Nums[5]); end; Canvas.Ellipse(Trunc(Nums[0]),Trunc(Nums[1]),Trunc(Nums[2]),Trunc(Nums[3])); Result:= True; end else if Inst = 'ARC' then begin Pn.Width:= Trunc(Nums[8]); Canvas.Arc(Trunc(Nums[0]),Trunc(Nums[1]),Trunc(Nums[2]),Trunc(Nums[3]), Trunc(Nums[4]),Trunc(Nums[5]),Trunc(Nums[6]),Trunc(Nums[7])); Result:= True; end else if Inst = 'TXT' then begin Canvas.Font.Size:= Trunc(Nums[2]); Br.Style:= bsClear; Pn.Style:= psSolid; T:= Cmd; Delete(T, 1, Pos(' ', T)); Delete(T, 1, Pos(',', T)); Delete(T, 1, Pos(',', T)); Delete(T, 1, Pos(',', T)); Canvas.TextOut(Trunc(Nums[0]), Trunc(Nums[1]), T); Result:= True; end; end else begin //No space found, not a valid command end; end; end; end; What I'd like to know is what's a good lightweight third-party scripting engine I could use to accomplish this? I would hate to implement parsing of IF, THEN, ELSE, END, IFELSE, IFEND, and all those necessary commands. I need simply the ability to tell the scripting engine if certain properties meet certain conditions, it needs to draw the object a certain way. The light example above is only one scenario, but the same solution needs to also be applicable to other scenarios, such as a door being open or closed, locked or unlocked, and draw it a different way accordingly. This needs to be implemented in the object script drawing level. I can't hard-code any of these scripting/drawing rules, the drawing needs to be controlled based on the current state of the object, and I may also wish to draw a light a certain shade or darkness depending on how dimmed the light is.

• How to properly add texture to multi-fixture/shape b2Body

  - by Blazej Wdowikowski

  Hello to everyone this is my first poste here I hope that will be not fail start. At start I must say I make part 1 in Ray's Tutorial "How To Make A Game Like Fruit Ninja With Box2D and Cocos2D". But I wonder what when I want make more complex body with texture? Simple just add n b2FixtureDef to the same body. OK but what about texture? If I will take code from that tutorial it only fill last fixture. Probably it does not takes every b2Vec2 point. I was right, it did not. So quick refactor and from that -(id)initWithTexture:(CCTexture2D*)texture body:(b2Body*)body original:(BOOL)original { // gather all the vertices from our Box2D shape b2Fixture *originalFixture = body->GetFixtureList(); b2PolygonShape *shape = (b2PolygonShape*)originalFixture->GetShape(); int vertexCount = shape->GetVertexCount(); NSMutableArray *points = [NSMutableArray arrayWithCapacity:vertexCount]; for(int i = 0; i < vertexCount; i++) { CGPoint p = ccp(shape->GetVertex(i).x * PTM_RATIO, shape->GetVertex(i).y * PTM_RATIO); [points addObject:[NSValue valueWithCGPoint:p]]; } if ((self = [super initWithPoints:points andTexture:texture])) { _body = body; _body->SetUserData(self); _original = original; // gets the center of the polygon _centroid = self.body->GetLocalCenter(); // assign an anchor point based on the center self.anchorPoint = ccp(_centroid.x * PTM_RATIO / texture.contentSize.width, _centroid.y * PTM_RATIO / texture.contentSize.height); } return self; } I came up with that -(id)initWithTexture:(CCTexture2D*)texture body:(b2Body*)body original:(BOOL)original { int vertexCount = 0; //gather total number of b2Vect2 points b2Fixture *currentFixture = body->GetFixtureList(); while (currentFixture) { //new b2PolygonShape *shape = (b2PolygonShape*)currentFixture->GetShape(); vertexCount += shape->GetVertexCount(); currentFixture = currentFixture->GetNext(); } NSMutableArray *points = [NSMutableArray arrayWithCapacity:vertexCount]; // gather all the vertices from our Box2D shape b2Fixture *originalFixture = body->GetFixtureList(); while (originalFixture) { //new NSLog((NSString*)@"-"); b2PolygonShape *shape = (b2PolygonShape*)originalFixture->GetShape(); int currentVertexCount = shape->GetVertexCount(); for(int i = 0; i < currentVertexCount; i++) { CGPoint p = ccp(shape->GetVertex(i).x * PTM_RATIO, shape->GetVertex(i).y * PTM_RATIO); [points addObject:[NSValue valueWithCGPoint:p]]; } originalFixture = originalFixture->GetNext(); } if ((self = [super initWithPoints:points andTexture:texture])) { _body = body; _body->SetUserData(self); _original = original; // gets the center of the polygon _centroid = self.body->GetLocalCenter(); // assign an anchor point based on the center self.anchorPoint = ccp(_centroid.x * PTM_RATIO / texture.contentSize.width,_centroid.y * PTM_RATIO / texture.contentSize.height); } return self; } I was working for simple two fixtures body like b2BodyDef bodyDef; bodyDef.type = b2_dynamicBody; bodyDef.position = position; bodyDef.angle = rotation; b2Body *body = world->CreateBody(&bodyDef); b2FixtureDef fixtureDef; fixtureDef.density = 1.0; fixtureDef.friction = 0.5; fixtureDef.restitution = 0.2; fixtureDef.filter.categoryBits = 0x0001; fixtureDef.filter.maskBits = 0x0001; b2Vec2 vertices[] = { b2Vec2(0.0/PTM_RATIO,50.0/PTM_RATIO), b2Vec2(0.0/PTM_RATIO,0.0/PTM_RATIO), b2Vec2(50.0/PTM_RATIO,30.1/PTM_RATIO), b2Vec2(60.0/PTM_RATIO,60.0/PTM_RATIO) }; b2PolygonShape shape; shape.Set(vertices, 4); fixtureDef.shape = &shape; body->CreateFixture(&fixtureDef); b2Vec2 vertices2[] = { b2Vec2(20.0/PTM_RATIO,50.0/PTM_RATIO), b2Vec2(20.0/PTM_RATIO,0.0/PTM_RATIO), b2Vec2(70.0/PTM_RATIO,30.1/PTM_RATIO), b2Vec2(80.0/PTM_RATIO,60.0/PTM_RATIO) }; shape.Set(vertices2, 4); fixtureDef.shape = &shape; body->CreateFixture(&fixtureDef); But if I try put secondary shape upper than first it starting wierd, texture goes crazy. For example not mention about more complex shapes. What's more if shapes have one common point texture will not render for them at all [For that I use Physics Edytor like in tutorial part1] BTW. I use PolygonSprite and in method createWithWorld... another shapes. Uff.. Question So my question is, why texture coords are in such a mess up? It's my modify method or just wrong approach? Maybe I should remove duplicated from points array?

• How to handle updated configuration when it's already been cloned for editing

  - by alexrussell

  Really sorry about the title that probably doesn't make much sense. Hopefully I can explain myself better here as it's something that's kinda bugged me for ages, and is now becoming a pressing concern as I write a bit of software with configuration. Most software comes with default configuration options stored in the app itself, and then there's a configuration file (let's say) that a user can edit. Once created/edited for the first time, subsequent updates to the application can not (easily) modify this configuration file for fear of clobbering the user's own changes to the default configuration. So my question is, if my application adds a new configurable parameter, what's the best way to aid discoverability of the setting and allow the user (developer) to override it as nicely as possible given the following constraints: I actually don't have a canonical default config in the application per se, it's more of a 'cascading filesystem'-like affair - the config template is stored in default/config.json and when the user wishes to edit the configuration, it's copied to user/config.json. If a user config is found it is used - there is no automatic overriding of a subset of keys, the whole new file is used and that's that. If there's no user config the default config is used. When a user wishes to edit the config they run a command to 'generate' it for them (which simply copies the config.json file from the default to the user directory). There is no UI for the configuration options as it's not appropriate to the userbase (think of my software as a library or something, the users are developers, the config is done in the user/config.json file). Due to my software being library-like there's no simple way to, on updating of the software, run some tasks automatically (so any ideas of look at the current config, compare to template config, add ing missing keys) aren't appropriate. The only solution I can think of right now is to say "there's a new config setting X" in release notes, but this doesn't seem ideal to me. If you want any more information let me know. The above specifics are not actually 100% true to my situation, but they represent the problem equally well with lower complexity. If you do want specifics, however, I can explain the exact setup. Further clarification of the type of configuration I mean: think of the Atom code editor. There appears to be a default 'template' config file somewhere, but as soon as a configuration option is edited ~/.atom/config.cson is generated and the setting goes in there. From now on is Atom is updated and gets a new configuration key, this file cannot be overwritten by Atom without a lot of effort to ensure that the addition/modification of the key does not clobber. In Atom's case, because there is a GUI for editing settings, they can get away with just adding the UI for the new setting into the UI to aid 'discoverability' of the new setting. I don't have that luxury. Clarification of my constraints and what I'm actually looking for: The software I'm writing is actually a package for a larger system. This larger system is what provides the configuration, and the way it works is kinda fixed - I just do a config('some.key') kinda call and it knows to look to see if the user has a config clone and if so use it, otherwise use the default config which is part of my package. Now, while I could make my application edit the user's configuration files (there is a convention about where they're stored), it's generally not done, so I'd like to live with the constraints of the system I'm using if possible. And it's not just about discoverability either, one large concern is that the addition of a configuration key won't actually work as soon as the user has their own copy of the original template. Adding the key to the template won't make a difference as that file is never read. As such, I think this is actually quite a big flaw in the design of the configuration cascading system and thus needs to be taken up with my upstream. So, thinking about it, based on my constraints, I don't think there's going to be a good solution save for either editing the user's configuration or using a new config file every time there are updates to the default configuration. Even the release notes idea from above isn't doable as, if the user does not follow the advice, suddenly I have a config key with no value (user-defined or default). So the new question is this: what is the general way to solve the problem of having a default configuration in template config files and allowing a user to make user-specific version of these in order to override the defaults? A per-key cascade (rather than per-file cascade) where the user only specifies their overrides? In this case, what happens if a configuration value is an array - do we replace or append to the default (or, more realistically, how does the user specify whether they wish to replace or append to)? It seems like configuration is kinda hard, so how is it solved in the wild?

• #OOW 2012 : IaaS, Private Cloud, Multitenant Database, and X3H2M2

  - by Eric Bezille

  The title of this post is a summary of the 4 announcements made by Larry Ellison today, during the opening session of Oracle Open World 2012... To know what's behind X3H2M2, you will have to wait a little, as I will go in order, beginning with the IaaS - Infrastructure as a Service - announcement. Oracle IaaS goes Public... and Private... Starting in 2004 with Fusion development, Oracle Cloud was launch last year to provide not only SaaS Application, based on standard development, but also the underlying PaaS, required to build the specifics, and required interconnections between applications, in and outside of the Cloud. Still, to cover the end-to-end Cloud  Services spectrum, we had to provide an Infrastructure as a Service, leveraging our Servers, Storage, OS, and Virtualization Technologies, all "Engineered Together". This Cloud Infrastructure, was already available for our customers to build rapidly their own Private Cloud either on SPARC/Solaris or x86/Linux... The second announcement made today bring that proposition a big step further : for cautious customers (like Banks, or sensible industries) who would like to benefits from the Cloud value of "as a Service", but don't want their Data out in the Cloud... We propose to them to operate the same systems, Exadata, Exalogic & SuperCluster, that are providing our Public Cloud Infrastructure, behind their firewall, in a Private Cloud model. Oracle 12c Multitenant Database This is also a major announcement made today, on what's coming with Oracle Database 12c : the ability to consolidate multiple databases with no extra additional  cost especially in terms of memory needed on the server node, which is often THE consolidation limiting factor. The principle could be compare to Solaris Zones, where, you will have a Database Container, who is "owning" the memory and Database background processes, and "Pluggable" Database in this Database Container. This particular feature is a strong compelling event to evaluate rapidly Oracle Database 12c once it will be available, as this is major step forward into true Database consolidation with Multitenancy on a shared (optimized) infrastructure. X3H2M2, enabling the new Exadata X3 in-Memory Database Here we are :  X3H2M2 stands for X3 (the new version of Exadata announced also today) Heuristic Hierarchical Mass Memory, providing the capability to keep most if not all the Data in the memory cache hierarchy. Of course, this is the major software enhancement of the new X3 Exadata machine, but as this is a software, our current customers would be able to benefit from it on their existing systems by upgrading to the new release. But that' not the only thing that we did with X3, at the same time we have upgraded everything : the CPUs, adding more cores per server node (16 vs. 12, with the arrival of Intel E5 / Sandy Bridge), the memory with 512GB memory as well per node,  and the new Flash Fire card, bringing now up to 22 TB of Flash cache. All of this 4TB of RAM + 22TB of Flash being use cleverly not only for read but also for write by the X3H2M2 algorithm... making a very big difference compare to traditional storage flash extension. But what does those extra performances brings to you on an already very efficient system: double your performances compare to the fastest storage array on the market today (including flash) and divide you storage price x10 at the same time... Something to consider closely this days... Especially that we also announced the availability of a new Exadata X3-2 8th rack : a good starting point. As you have seen a major opening for this year again with true innovation. But that was not the only thing that we saw today, as before Larry's talk, Fujitsu did introduce more in deep the up coming new SPARC processor, that they are co-developing with us. And as such Andrew Mendelsohn - Senior Vice President Database Server Technologies came on stage to explain that the next step after I/O optimization for Database with Exadata, was to accelerate the Database at execution level by bringing functions in the SPARC processor silicium. All in all, to process more and more Data... The big theme of the day... and of the Oracle User Groups Conferences that were also happening today and where I had the opportunity to attend some interesting sessions on practical use cases of Big Data one in Finances and Fraud profiling and the other one on practical deployment of Oracle Exalytics for Data Analytics. In conclusion, one picture to try to size Oracle Open World ... and you can understand why, with such a rich content... and this only the first day !

• Impressions and Reactions from Alliance 2012

  - by user739873

  Alliance 2012 has come to a conclusion.  What strikes me about every Alliance conference is the amazing amount of collaboration and cooperation I see across higher education in the sharing of best practices around the entire Oracle PeopleSoft software suite, not just the student information system (Oracle’s PeopleSoft Campus Solutions).  In addition to the vibrant U.S. organization, it's gratifying to see the growth in the international attendance again this year, with an EMEA HEUG organizing to complement the existing groups in the Netherlands, South Africa, and the U.K.  Their first meeting is planned for London in October, and I suspect they'll be surprised at the amount of interest and attendance. In my discussions with higher education IT and functional leadership at Alliance there were a number of instances where concern was expressed about Oracle's commitment to higher education as an industry, primarily because of a lack of perceived innovation in the applications that Oracle develops for this market. Here I think perception and reality are far apart, and I'd like to explain why I believe this to be true. First let me start with what I think drives this perception. Predominately it's in two areas. The first area is the user interface, both for students and faculty that interact with the system as "customers", and for those employees of the institution (faculty, staff, and sometimes students as well) that use the system in some kind of administrative role. Because the UI hasn't changed all that much from the PeopleSoft days, individuals perceive this as a dead product with little innovation and therefore Oracle isn't investing. The second area is around the integration of the higher education suite of applications (PeopleSoft Campus Solutions) and the rest of the Oracle software assets. Whether grown organically or acquired, there is an impressive array of middleware and other software products that could be leveraged much more significantly by the higher education applications than is currently the case today. This is also perceived as lack of investment. Let me address these two points.  First the UI.  More is being done here than ever before, and the PAG and other groups where this was discussed at Alliance 2012 were more numerous than I've seen in any past meeting. Whether it's Oracle development leveraging web services or some extremely early but very promising work leveraging the recent Endeca acquisition (see some cool examples here) there are a lot of resources aimed at this issue.  There are also some amazing prototypes being developed by our UX (user experience team) that will eventually make their way into the higher education applications realm - they had an impressive setup at Alliance.  Hopefully many of you that attended found this group. If not, the senior leader for that team Jeremy Ashley will be a significant contributor of content to our summer Industry Strategy Council meeting in Washington in June. In the area of integration with other elements of the Oracle stack, this is also an area of focus for the company and my team.  We're making this a priority especially in the areas of identity management and security, leveraging WebCenter more effectively for content, imaging, and mobility, and driving towards the ultimate objective of WebLogic Suite as our platform for SOA, links to learning management systems (SAIP), and content. There is also much work around business intelligence centering on OBI applications. But at the end of the day we get enormous value from the HEUG (higher education user group) and the various subgroups formed as a part of this community that help us align and prioritize our investments, whether it's around better integration with other Oracle products or integration with partner offerings.  It's one of the healthiest, mutually beneficial relationships between customers and an Education IT concern that exists on the globe. And I can't avoid mentioning that this kind of relationship between higher education and the corporate IT community that can truly address the problems of efficiency and effectiveness, institutional excellence (which starts with IT) and student success.  It's not (in my opinion) going to be solved through community source - cost and complexity only increase in that model and in the end higher education doesn't ultimately focus on core competencies: educating, developing, and researching.  While I agree with some of what Michael A. McRobbie wrote in his EDUCAUSE Review article (Information Technology: A View from Both Sides of the President’s Desk), I take strong issue with his assertion that the "the IT marketplace is just the opposite of long-term stability...."  Sure there has been healthy, creative destruction in the past 2-3 decades, but this has had the effect of, in the aggregate, benefiting education with greater efficiency, more innovation and increased stability as larger, more financially secure firms acquire and develop integrated solutions.

• SQL SERVER – Backing Up and Recovering the Tail End of a Transaction Log – Notes from the Field #042

  - by Pinal Dave

  [Notes from Pinal]: The biggest challenge which people face is not taking backup, but the biggest challenge is to restore a backup successfully. I have seen so many different examples where users have failed to restore their database because they made some mistake while they take backup and were not aware of the same. Tail Log backup was such an issue in earlier version of SQL Server but in the latest version of SQL Server, Microsoft team has fixed the confusion with additional information on the backup and restore screen itself. Now they have additional information, there are a few more people confused as they have no clue about this. Previously they did not find this as a issue and now they are finding tail log as a new learning. Linchpin People are database coaches and wellness experts for a data driven world. In this 42nd episode of the Notes from the Fields series database expert Tim Radney (partner at Linchpin People) explains in a very simple words, Backing Up and Recovering the Tail End of a Transaction Log. Many times when restoring a database over an existing database SQL Server will warn you about needing to make a tail end of the log backup. This might be your reminder that you have to choose to overwrite the database or could be your reminder that you are about to write over and lose any transactions since the last transaction log backup. You might be asking yourself “What is the tail end of the transaction log”. The tail end of the transaction log is simply any committed transactions that have occurred since the last transaction log backup. This is a very crucial part of a recovery strategy if you are lucky enough to be able to capture this part of the log. Most organizations have chosen to accept some amount of data loss. You might be shaking your head at this statement however if your organization is taking transaction logs backup every 15 minutes, then your potential risk of data loss is up to 15 minutes. Depending on the extent of the issue causing you to have to perform a restore, you may or may not have access to the transaction log (LDF) to be able to back up those vital transactions. For example, if the storage array or disk that holds your transaction log file becomes corrupt or damaged then you wouldn’t be able to recover the tail end of the log. If you do have access to the physical log file then you can still back up the tail end of the log. In 2013 I presented a session at the PASS Summit called “The Ultimate Tail Log Backup and Restore” and have been invited back this year to present it again. During this session I demonstrate how you can back up the tail end of the log even after the data file becomes corrupt. In my demonstration I set my database offline and then delete the data file (MDF). The database can’t become more corrupt than that. I attempt to bring the database back online to change the state to RECOVERY PENDING and then backup the tail end of the log. I can do this by specifying WITH NO_TRUNCATE. Using NO_TRUNCATE is equivalent to specifying both COPY_ONLY and CONTINUE_AFTER_ERROR. It as its name says, does not try to truncate the log. This is a great demo however how could I achieve backing up the tail end of the log if the failure destroys my entire instance of SQL and all I had was the LDF file? During my demonstration I also demonstrate that I can attach the log file to a database on another instance and then back up the tail end of the log. If I am performing proper backups then my most recent full, differential and log files should be on a server other than the one that crashed. I am able to achieve this task by creating new database with the same name as the failed database. I then set the database offline, delete my data file and overwrite the log with my good log file. I attempt to bring the database back online and then backup the log with NO_TRUNCATE just like in the first example. I encourage each of you to view my blog post and watch the video demonstration on how to perform these tasks. I really hope that none of you ever have to perform this in production, however it is a really good idea to know how to do this just in case. It really isn’t a matter of “IF” you will have to perform a restore of a production system but more of a “WHEN”. Being able to recover the tail end of the log in these sever cases could be the difference of having to notify all your business customers of data loss or not. If you want me to take a look at your server and its settings, or if your server is facing any issue we can Fix Your SQL Server. Note: Tim has also written an excellent book on SQL Backup and Recovery, a must have for everyone.

• iOS Support with Windows Azure Mobile Services – now with Push Notifications

  - by ScottGu

  A few weeks ago I posted about a number of improvements to Windows Azure Mobile Services. One of these was the addition of an Objective-C client SDK that allows iOS developers to easily use Mobile Services for data and authentication.  Today I'm excited to announce a number of improvement to our iOS SDK and, most significantly, our new support for Push Notifications via APNS (Apple Push Notification Services).  This makes it incredibly easy to fire push notifications to your iOS users from Windows Azure Mobile Service scripts. Push Notifications via APNS We've provided two complete tutorials that take you step-by-step through the provisioning and setup process to enable your Windows Azure Mobile Service application with APNS (Apple Push Notification Services), including all of the steps required to configure your application for push in the Apple iOS provisioning portal: Getting started with Push Notifications - iOS Push notifications to users by using Mobile Services - iOS Once you've configured your application in the Apple iOS provisioning portal and uploaded the APNS push certificate to the Apple provisioning portal, it's just a matter of uploading your APNS push certificate to Mobile Services using the Windows Azure admin portal: Clicking the “upload” within the “Push” tab of your Mobile Service allows you to browse your local file-system and locate/upload your exported certificate.  As part of this you can also select whether you want to use the sandbox (dev) or production (prod) Apple service: Now, the code to send a push notification to your clients from within a Windows Azure Mobile Service is as easy as the code below: push.apns.send(deviceToken, {      alert: 'Toast: A new Mobile Services task.',      sound: 'default' }); This will cause Windows Azure Mobile Services to connect to APNS (Apple Push Notification Service) and send a notification to the iOS device you specified via the deviceToken: Check out our reference documentation for full details on how to use the new Windows Azure Mobile Services apns object to send your push notifications. Feedback Scripts An important part of working with any PNS (Push Notification Service) is handling feedback for expired device tokens and channels. This typically happens when your application is uninstalled from a particular device and can no longer receive your notifications. With Windows Notification Services you get an instant response from the HTTP server.  Apple’s Notification Services works in a slightly different way and provides an additional endpoint you can connect to poll for a list of expired tokens. As with all of the capabilities we integrate with Mobile Services, our goal is to allow developers to focus more on building their app and less on building infrastructure to support their ideas. Therefore we knew we had to provide a simple way for developers to integrate feedback from APNS on a regular basis.  This week’s update now includes a new screen in the portal that allows you to optionally provide a script to process your APNS feedback – and it will be executed by Mobile Services on an ongoing basis: This script is invoked periodically while your service is active. To poll the feedback endpoint you can simply call the apns object's getFeedback method from within this script: push.apns.getFeedback({       success: function(results) {           // results is an array of objects with a deviceToken and time properties      } }); This returns you a list of invalid tokens that can now be removed from your database. iOS Client SDK improvements Over the last month we've continued to work with a number of iOS advisors to make improvements to our Objective-C SDK. The SDK is being developed under an open source license (Apache 2.0) and is available on github. Many of the improvements are behind the scenes to improve performance and memory usage. However, one of the biggest improvements to our iOS Client API is the addition of an even easier login method.  Below is the Objective-C code you can now write to invoke it: [client loginWithProvider:@"twitter"                     onController:self                        animated:YES                      completion:^(MSUser *user, NSError *error) {      // if no error, you are now logged in via twitter }]; This code will automatically present and dismiss our login view controller as a modal dialog on the specified controller.  This does all the hard work for you and makes login via Twitter, Google, Facebook and Microsoft Account identities just a single line of code. My colleague Josh just posted a short video demonstrating these new features which I'd recommend checking out: Summary The above features are all now live in production and are available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using Mobile Services today. Visit the Windows Azure Mobile Developer Center to learn more about how to build apps with Mobile Services. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• Draw Bug 2D player Camera

  - by RedShft

  I have just implemented a 2D player camera for my game, everything works properly except the player on the screen jitters when it moves between tiles. What I mean by jitter, is that if the player is moving the camera updates the tileset to be drawn and if the player steps to the right, the camera snaps that way. The movement is not smooth. I'm guessing this is occurring because of how I implemented the function to calculate the current viewable area or how my draw function works. I'm not entirely sure how to fix this. This camera system was entirely of my own creation and a first attempt at that, so it's very possible this is not a great way of doing things. My camera class, pulls information from the current tileset and calculates the viewable area. Right now I am targettng a resolution of 800 by 600. So I try to fit the appropriate amount of tiles for that resolution. My camera class, after calculating the current viewable tileset relative to the players location, returns a slice of the original tileset to be drawn. This tileset slice is updated every frame according to the players position. This slice is then passed to the map class, which draws the tile on screen. //Map Draw Function //This draw function currently matches the GID of the tile to it's location on the //PNG file of the tileset and then draws this portion on the screen void Draw(SDL_Surface* background, int[] _tileSet) { enforce( tilesetImage != null, "Tileset is null!"); enforce( background != null, "BackGround is null!"); int i = 0; int j = 0; SDL_Rect DestR, SrcR; SrcR.x = 0; SrcR.y = 0; SrcR.h = 32; SrcR.w = 32; foreach(tile; _tileSet) { //This code is matching the current tiles ID to the tileset image SrcR.x = cast(short)(tileWidth * (tile >= 11 ? (tile - ((tile / 10) * 10) - 1) : tile - 1)); SrcR.y = cast(short)(tileHeight * (tile > 10 ? (tile / 10) : 0)); //Applying the tile to the surface SDL_BlitSurface( tilesetImage, &SrcR, background, &DestR ); //this keeps track of what column/row we are on i++; if ( i == mapWidth ) { i = 0; j++; } DestR.x = cast(short)(i * tileWidth); DestR.y = cast(short)(j * tileHeight); } } //Camera Class class Camera { private: //A rectangle representing the view area SDL_Rect viewArea; //In number of tiles int viewAreaWidth; int viewAreaHeight; //This is the x and y coordinate of the camera in MAP SPACE IN PIXELS vect2 cameraCoordinates; //The player location in map space IN PIXELS vect2 playerLocation; //This is the players location in screen space; vect2 playerScreenLoc; int playerTileCol; int playerTileRow; int cameraTileCol; int cameraTileRow; //The map is stored in a single array with the tile ids //this corresponds to the index of the starting and ending tile int cameraStartTile, cameraEndTile; //This is a slice of the current tile set int[] tileSetCopy; int mapWidth; int mapHeight; int tileWidth; int tileHeight; public: this() { this.viewAreaWidth = 25; this.viewAreaHeight = 19; this.cameraCoordinates = vect2(0, 0); this.playerLocation = vect2(0, 0); this.viewArea = SDL_Rect (0, 0, 0, 0); this.tileWidth = 32; this.tileHeight = 32; } void Init(vect2 playerPosition, ref int[] tileSet, int mapWidth, int mapHeight ) { playerLocation = playerPosition; this.mapWidth = mapWidth; this.mapHeight = mapHeight; CalculateCurrentCameraPosition( tileSet, playerPosition ); //writeln( "Tile Set Copy: ", tileSetCopy ); //writeln( "Orginal Tile Set: ", tileSet ); } void CalculateCurrentCameraPosition( ref int[] tileSet, vect2 playerPosition ) { playerLocation = playerPosition; playerTileCol = cast(int)((playerLocation.x / tileWidth) + 1); playerTileRow = cast(int)((playerLocation.y / tileHeight) + 1); //writeln( "Player Tile (Column, Row): ","(", playerTileCol, ", ", playerTileRow, ")"); cameraTileCol = playerTileCol - (viewAreaWidth / 2); cameraTileRow = playerTileRow - (viewAreaHeight / 2); CameraMapBoundsCheck(); //writeln( "Camera Tile Start (Column, Row): ","(", cameraTileCol, ", ", cameraTileRow, ")"); cameraStartTile = ( (cameraTileRow - 1) * mapWidth ) + cameraTileCol - 1; //writeln( "Camera Start Tile: ", cameraStartTile ); cameraEndTile = cameraStartTile + ( viewAreaWidth * viewAreaHeight ) * 2; //writeln( "Camera End Tile: ", cameraEndTile ); tileSetCopy = tileSet[cameraStartTile..cameraEndTile]; } vect2 CalculatePlayerScreenLocation() { cameraCoordinates.x = cast(float)(cameraTileCol * tileWidth); cameraCoordinates.y = cast(float)(cameraTileRow * tileHeight); playerScreenLoc = playerLocation - cameraCoordinates + vect2(32, 32);; //writeln( "Camera Coordinates: ", cameraCoordinates ); //writeln( "Player Location (Map Space): ", playerLocation ); //writeln( "Player Location (Screen Space): ", playerScreenLoc ); return playerScreenLoc; } void CameraMapBoundsCheck() { if( cameraTileCol < 1 ) cameraTileCol = 1; if( cameraTileRow < 1 ) cameraTileRow = 1; if( cameraTileCol + 24 > mapWidth ) cameraTileCol = mapWidth - 24; if( cameraTileRow + 19 > mapHeight ) cameraTileRow = mapHeight - 19; } ref int[] GetTileSet() { return tileSetCopy; } int GetViewWidth() { return viewAreaWidth; } }

• Processing Text and Binary (Blob, ArrayBuffer, ArrayBufferView) Payload in WebSocket - (TOTD #185)

  - by arungupta

  The WebSocket API defines different send(xxx) methods that can be used to send text and binary data. This Tip Of The Day (TOTD) will show how to send and receive text and binary data using WebSocket. TOTD #183 explains how to get started with a WebSocket endpoint using GlassFish 4. A simple endpoint from that blog looks like: @WebSocketEndpoint("/endpoint") public class MyEndpoint { public void receiveTextMessage(String message) { . . . } } A message with the first parameter of the type String is invoked when a text payload is received. The payload of the incoming WebSocket frame is mapped to this first parameter. An optional second parameter, Session, can be specified to map to the "other end" of this conversation. For example: public void receiveTextMessage(String message, Session session) {     . . . } The return type is void and that means no response is returned to the client that invoked this endpoint. A response may be returned to the client in two different ways. First, set the return type to the expected type, such as: public String receiveTextMessage(String message) { String response = . . . . . . return response; } In this case a text payload is returned back to the invoking endpoint. The second way to send a response back is to use the mapped session to send response using one of the sendXXX methods in Session, when and if needed. public void receiveTextMessage(String message, Session session) {     . . .     RemoteEndpoint remote = session.getRemote();     remote.sendString(...);     . . .     remote.sendString(...);    . . .    remote.sendString(...); } This shows how duplex and asynchronous communication between the two endpoints can be achieved. This can be used to define different message exchange patterns between the client and server. The WebSocket client can send the message as: websocket.send(myTextField.value); where myTextField is a text field in the web page. Binary payload in the incoming WebSocket frame can be received if ByteBuffer is used as the first parameter of the method signature. The endpoint method signature in that case would look like: public void receiveBinaryMessage(ByteBuffer message) {     . . . } From the client side, the binary data can be sent using Blob, ArrayBuffer, and ArrayBufferView. Blob is a just raw data and the actual interpretation is left to the application. ArrayBuffer and ArrayBufferView are defined in the TypedArray specification and are designed to send binary data using WebSocket. In short, ArrayBuffer is a fixed-length binary buffer with no format and no mechanism for accessing its contents. These buffers are manipulated using one of the views defined by one of the subclasses of ArrayBufferView listed below: Int8Array (signed 8-bit integer or char) Uint8Array (unsigned 8-bit integer or unsigned char) Int16Array (signed 16-bit integer or short) Uint16Array (unsigned 16-bit integer or unsigned short) Int32Array (signed 32-bit integer or int) Uint32Array (unsigned 16-bit integer or unsigned int) Float32Array (signed 32-bit float or float) Float64Array (signed 64-bit float or double) WebSocket can send binary data using ArrayBuffer with a view defined by a subclass of ArrayBufferView or a subclass of ArrayBufferView itself. The WebSocket client can send the message using Blob as: blob = new Blob([myField2.value]);websocket.send(blob); where myField2 is a text field in the web page. The WebSocket client can send the message using ArrayBuffer as: var buffer = new ArrayBuffer(10);var bytes = new Uint8Array(buffer);for (var i=0; i<bytes.length; i++) { bytes[i] = i;}websocket.send(buffer); A concrete implementation of receiving the binary message may look like: @WebSocketMessagepublic void echoBinary(ByteBuffer data, Session session) throws IOException {    System.out.println("echoBinary: " + data);    for (byte b : data.array()) {        System.out.print(b);    }    session.getRemote().sendBytes(data);} This method is just printing the binary data for verification but you may actually be storing it in a database or converting to an image or something more meaningful. Be aware of TYRUS-51 if you are trying to send binary data from server to client using method return type. Here are some references for you: JSR 356: Java API for WebSocket - Specification (Early Draft) and Implementation (already integrated in GlassFish 4 promoted builds) TOTD #183 - Getting Started with WebSocket in GlassFish TOTD #184 - Logging WebSocket Frames using Chrome Developer Tools, Net-internals and Wireshark Subsequent blogs will discuss the following topics (not necessary in that order) ... Error handling Custom payloads using encoder/decoder Interface-driven WebSocket endpoint Java client API Client and Server configuration Security Subprotocols Extensions Other topics from the API

• Speed up executable program Linux. Bit Toggling

  - by AK_47

  I have a ZyBo circuit board which has a ArmV7 processor. I wrote a C program to output a clock and a corresponding data sequence on a PMOD. The PMOD has a switching speed of up to 50MHz. However, my program's created clock only has a max frequency of 115 Hz. I need this program to output as fast as possible because the PMOD I'm using is capable of 50MHz. I compiled my program with the following code line: gcc -ofast (c_program) Here is some sample code: #include <stdio.h> #include <stdlib.h> #define ARRAYSIZE 511 //________________________________________ //macro for the SIGNAL PMOD //________________________________________ //DATA //ZYBO Use Pin JE1 #define INIT_SIGNAL system("echo 54 > /sys/class/gpio/export"); system("echo out > /sys/class/gpio/gpio54/direction"); #define SIGNAL_ON system("echo 1 > /sys/class/gpio/gpio54/value"); #define SIGNAL_OFF system("echo 0 > /sys/class/gpio/gpio54/value"); //________________________________________ //macro for the "CLOCK" PMOD //________________________________________ //CLOCK //ZYBO Use Pin JE4 #define INIT_MYCLOCK system("echo 57 > /sys/class/gpio/export"); system("echo out > /sys/class/gpio/gpio57/direction"); #define MYCLOCK_ON system("echo 1 > /sys/class/gpio/gpio57/value"); #define MYCLOCK_OFF system("echo 0 > /sys/class/gpio/gpio57/value"); int main(void){ int myarray[ARRAYSIZE] = {//hard coded array for signal data 1,0,0,1,0,1,0,0,1,0,1,0,0,1,0,1,0,0,1,0,1,0,0,1,0,0,1,0,1,0,0,1,1,0,0,1,1,0,1,0,0,0,0,0,1,0,0,1,1,1,0,0,1,1,1,0,1,1,1,1,0,0,1,0,0,0,1,0,1,0,0,1,1,1,0,0,1,0,1,0,1,0,0,1,0,1,1,0,1,0,1,1,0,0,1,1,1,1,0,0,1,0,1,0,0,1,1,1,1,1,1,0,0,1,0,0,1,1,0,1,0,0,0,0,1,0,0,0,1,1,0,0,1,0,1,1,1,0,0,0,1,0,0,0,1,0,1,0,0,0,1,0,0,1,0,1,1,1,1,0,1,1,0,1,0,0,1,0,0,0,1,0,1,0,0,1,0,0,0,1,0,0,0,1,0,1,0,1,0,1,0,1,1,0,0,0,0,0,0,0,0,1,0,1,1,0,1,1,1,1,1,0,0,1,1,1,0,0,1,1,0,1,1,0,1,1,1,0,0,1,1,1,1,1,0,0,1,0,1,0,1,0,1,1,0,1,0,0,0,1,1,1,0,1,0,1,0,1,0,1,0,1,0,1,0,0,1,0,0,0,0,1,1,1,0,1,1,1,1,0,1,1,0,1,0,1,0,1,0,0,1,0,1,1,1,0,1,1,1,0,0,1,1,1,0,1,0,0,1,0,1,1,1,1,1,0,1,1,1,1,1,1,1,0,1,1,0,0,1,0,1,1,0,1,0,1,1,1,0,0,0,0,0,1,0,0,0,1,0,1,1,1,1,1,1,1,0,0,0,0,0,1,1,0,1,1,1,1,1,1,1,1,0,1,1,0,1,0,0,0,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1,0,1,1,1,0,1,0,1,1,1,0,0,0,1,0,1,0,1,0,0,1,1,0,0,1,1,0,1,0,0,1,0,0,1,0,1,1,1,1,1,1,0,1,1,0,1,0,1,1,1,1,1,1,0,0,1,1,0,1,1,0,0,1,1,0,1,1,0,1,0,1,0,1,0,1,0,0,1,1,1,0,1,1,0,0,0,0,1,1,0,1,1,0,1,1,1,1,1,1,1,0,1,0,1,1,0,0,0,0,0,0,0,0,0,0,0 }; INIT_SIGNAL INIT_MYCLOCK; //infinite loop int i; do{ i = 0; do{ /* 1020 is chosen because it is twice the size needed allowing for the changes in the clock.

One pin for the data and another for the clock). That was the only way I knew to tell the system to output a voltage. What can I do to make my executable program output to be at least in the magnitude of MegaHertz?

  Robin Harris of Storagemojo pointed to an interesting article about about deduplication and it's impact to the resiliency of your data against data corruption on ACM Queue. The problem in short: A considerable number of filesystems store important metadata at multiple locations. For example the ZFS rootblock is copied to three locations. Other filesystems have similar provisions to protect their metadata. However you can easily proof, that the rootblock pointer in the uberblock of ZFS for example is pointing to blocks with absolutely equal content in all three locatition (with zdb -uu and zdb -r). It has to be that way, because they are protected by the same checksum. A number of devices offer block level dedup, either as an option or as part of their inner workings. However when you store three identical blocks on them and the devices does block level dedup internally, the device may just deduplicated your redundant metadata to a block stored just once that is stored on the non-voilatile storage. When this block is corrupted, you have essentially three corrupted copies. Three hit with one bullet. This is indeed an interesting problem: A device doing deduplication doesn't know if a block is important or just a datablock. This is the reason why I like deduplication like it's done in ZFS. It's an integrated part and so important parts don't get deduplicated away. A disk accessed by a block level interface doesn't know anything about the importance of a block. A metadata block is nothing different to it's inner mechanism than a normal data block because there is no way to tell that this is important and that those redundancies aren't allowed to fall prey to some clever deduplication mechanism. Robin talks about this in regard of the Sandforce disk controllers who use a kind of dedup to reduce some of the nasty effects of writing data to flash, but the problem is much broader. However this is relevant whenever you are using a device with block level deduplication. It's just the point that you have to activate it for most implementation by command, whereas certain devices do this by default or by design and you don't know about it. However I'm not perfectly sure about that ? given that storage administration and server administration are often different groups with different business objectives I would ask your storage guys if they have activated dedup without telling somebody elase on their boxes in order to speak less often with the storage sales rep. The problem is even more interesting with ZFS. You may use ditto blocks to protect important data to store multiple copies of data in the pool to increase redundancy, even when your pool just consists out of one disk or just a striped set of disk. However when your device is doing dedup internally it may remove your redundancy before it hits the nonvolatile storage. You've won nothing. Just spend your disk quota on the the LUNs in the SAN and you make your disk admin happy because of the good dedup ratio However you can just fall in this specific "deduped ditto block"trap when your pool just consists out of a single device, because ZFS writes ditto blocks on different disks, when there is more than just one disk. Yet another reason why you should spend some extra-thought when putting your zpool on a single LUN, especially when the LUN is sliced and dices out of a large heap of storage devices by a storage controller. However I have one problem with the articles and their specific mention of ZFS: You can just hit by this problem when you are using the deduplicating device for the pool. However in the specifically mentioned case of SSD this isn't the usecase. Most implementations of SSD in conjunction with ZFS are hybrid storage pools and so rotating rust disk is used as pool and SSD are used as L2ARC/sZIL. And there it simply doesn't matter: When you really have to resort to the sZIL (your system went down, it doesn't matter of one block or several blocks are corrupt, you have to fail back to the last known good transaction group the device. On the other side, when a block in L2ARC is corrupt, you simply read it from the pool and in HSP implementations this is the already mentioned rust. In conjunction with ZFS this is more interesting when using a storage array, that is capable to do dedup and where you use LUNs for your pool. However as mentioned before, on those devices it's a user made decision to do so, and so it's less probable that you deduplicating your redundancies. Other filesystems lacking acapability similar to hybrid storage pools are more "haunted" by this problem of SSD using dedup-like mechanisms internally, because those filesystem really store the data on the the SSD instead of using it just as accelerating devices. However at the end Robin is correct: It's jet another point why protecting your data by creating redundancies by dispersing it several disks (by mirror or parity RAIDs) is really important. No dedup mechanism inside a device can dedup away your redundancy when you write it to a totally different and indepenent device.

• Encrypt images before uploading to Dropbox [migrated]

  - by Cherry

  I want to encrypt a file first before the file will be uploaded to the dropbox. So i have implement the encryption inside the uploading of the codes. However, there is an error after i integrate the codes together. Where did my mistake go wrong? Error at putFileOverwriteRequest and it says The method putFileOverwriteRequest(String, InputStream, long, ProgressListener) in the type DropboxAPI is not applicable for the arguments (String, FileOutputStream, long, new ProgressListener(){}) Another problem is that this FileOutputStream fis = new FileOutputStream(new File("dont know what to put in this field")); i do not know where to put the file so that after i read the file, it will call the path and then upload to the Dropbox. Anyone is kind to help me in this? As time is running out for me and i still cant solve the problem. Thank you in advance.

• Deep Cloning C++ class that inherits CCNode in Cocos2dx

  - by A Devanney

  I stuck with something in Cocos2dx ... I'm trying to deep clone one of my classes that inherits CCNode. Basically i have.... GameItem* pTemp = new GameItem(*_actualItem); // loops through all the blocks in gameitem and updates their position pTemp->moveDown(); // if in boundary or collision etc... if (_gameBoard->isValidMove(pTemp)) { _actualItem = pTemp; // display the position CCLog("pos (1) --- (X : %d,Y : %d)", _actualItem->getGridX(),_actualItem->getGridY()); } Then doesn't work, because the gameitem inherits CCNode and has the collection of another class that also inherits CCNode. its just creating a shallow copy and when you look at children of the gameitem node in the copy, just point to the original? class GameItem : public CCNode { // maps to the actual grid position of the shape CCPoint* _rawPosition; // tracks the current grid position int _gridX, _gridY; // tracks the change if the item has moved CCPoint _offset; public: //constructors GameItem& operator=(const GameItem& item); GameItem(Shape shape); ... } then in the implementation.... GameItem& GameItem::operator=(const GameItem& item) { _gridX = item.getGridX(); _gridY = item.getGridY(); _offset = item.getOffSet(); _rawPosition = item.getRawPosition(); // how do i copy the node? return *this; } // shape contains an array of position for the game character GameItem::GameItem(Shape shape) { _rawPosition = shape.getShapePositions(); //loop through all blocks in position for (int i = 0; i < 7; i++) { // get the position of the first block in the shape and add to the position of the first block int x = (int) (getRawPosition()[i].x + getGridX()); int y = (int) (getRawPosition()[i].y + getGridY()); //instantiate a block with the position and type Block* block = Block::blockWithFile(x,y,(i+1), shape); // add the block to the this node this->addChild(block); } } And for clarity here is the block class class Block : public CCNode{ private: // using composition over inheritance CCSprite* _sprite; // tracks the current grid position int _gridX, _gridY; // used to store actual image number int _blockNo; public: Block(void); Block(int gridX, int gridY, int blockNo); Block& operator=(const Block& block); // static constructor for the creation of a block static Block* blockWithFile(int gridX, int gridY,int blockNo, Shape shape); ... } The blocks implementation..... Block& Block::operator=(const Block& block) { _sprite = new CCSprite(*block._sprite); _gridX = block._gridX; _gridY = block._gridY; _blockNo = block._blockNo; //again how to clone CCNode? return *this; } Block* Block::blockWithFile(int gridX, int gridY,int blockNo, Shape shape) { Block* block = new Block(); if (block && block->initBlockWithFile(gridX, gridY,blockNo, shape)) { block->autorelease(); return block; } CC_SAFE_DELETE(block); return NULL; } bool Block::initBlockWithFile(int gridX, int gridY,int blockNo, Shape shape) { setGridX(gridX); setGridY(gridY); setBlockNo(blockNo); const char* characterImg = helperFunctions::Format(shape.getFileName(),blockNo); // add to the spritesheet CCTexture2D* gameArtTexture = CCTextureCache::sharedTextureCache()->addImage("Character.pvr.ccz"); CCSpriteBatchNode::createWithTexture(gameArtTexture); // block settings _sprite = CCSprite::createWithSpriteFrameName(characterImg); // set the position of the block and add it to the layer this->setPosition(CONVERTGRIDTOACTUALPOS_X_Y(gridX,gridY)); this->addChild(_sprite); return true; } Any ideas are welcome at this point!! thanks

• Copies of GameScene created when called additional times

  - by Orin MacGregor

  I have a game with a level select managed by a SceneManager, which basically just uses ReplaceScene. The first time I load a level everything works fine. On subsequent calls, for example: completing the level and continuing to the next, things blow up. The level loads fine, but when I try to pan the map or try to move the player the game crashes. Debugging through I found that there are multiple occurrences of self and related children like player and mapLayer. As a test, I put this code in my ccTouchesBegan: NSLog(@"test %i", [self retainCount]); The first time a level is loaded, it gives: test 2 The second time I load a level it gives: test 2 test 1 as in it spits out both values by looping through twice, not just appending an output to the last. It continues with this pattern for each subsequent load. So the third time will give 2 1 1. Particular code that causes the game to crash involve calling _tileMap.tileSize because there is a second GameScene with a tileMap that was supposedly destroyed, so it has tileSize and mapSize of 0. I noticed dealloc doesn't really ever get called, so I tried to manage some things with -(void) onExit -(void) onExit { [self unscheduleAllSelectors]; [_player stopAllActions]; //stop any animations just in case. normally handled in ccTouchesEnded [self removeAllChildrenWithCleanup:YES]; } I never replace the GameScene while I'm in a GameScene; if the level is completed it goes to a GameOver scene, or I use a back button that goes to the LevelSelect scene. This is [the relevant parts of] my init, in case something like the adding of children matters: -(id) init { _mapLayer = [CCLayer node]; //load data for level GameData *gameData = [GameDataParser loadData]; int selectedChapter = gameData.selectedChapter; int selectedLevel = gameData.selectedLevel; Levels *chapterLevels = [LevelParser loadLevelsForChapter:selectedChapter]; //loop until we get selected level, then do stuff for (Level *level in chapterLevels.levels) { if (level.number == selectedLevel) { //load the level map _tileMap = [CCTMXTiledMap tiledMapWithTMXFile:level.file]; } } _background = [_tileMap layerNamed:@"Background"]; _foreground = [_tileMap layerNamed:@"Foreground"]; _meta = [_tileMap layerNamed:@"Meta"]; _meta.visible = NO; //initialize Spawn Point object and place player there CCTMXObjectGroup *objects = [_tileMap objectGroupNamed:@"Objects"]; NSAssert(objects != nil, @"'Objects' object group not found"); NSMutableDictionary *spawnPoint = [objects objectNamed:@"SpawnPoint"]; NSAssert(spawnPoint != nil, @"SpawnPoint object not found"); int x = [[spawnPoint valueForKey:@"x"] intValue] / retinaScaling; int y = [[spawnPoint valueForKey:@"y"] intValue] / retinaScaling; //setup animations [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"MouseRightAnim_24x21.plist"]; CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"MouseRightAnim_24x21.png"]; [_mapLayer addChild:spriteSheet z:1]; NSMutableArray *rightAnimFrames = [NSMutableArray array]; for(int i = 1; i <= 3; ++i) { [rightAnimFrames addObject: [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: [NSString stringWithFormat:@"MouseRight%d_24x21.png", i]]]; } CCAnimation *rightAnim = [CCAnimation animationWithSpriteFrames:rightAnimFrames delay:0.1f]; self.player = [CCSprite spriteWithSpriteFrameName:@"MouseRight2_24x21.png"]; _player.position = ccp(x, y); self.rightAction = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:rightAnim]]; rightAnim.restoreOriginalFrame = NO; [spriteSheet addChild:_player]; //get map size in pixels mapHeight = _tileMap.contentSize.height; mapWidth = _tileMap.contentSize.width; //setup defaults //this value works well for the calculation later, trial and error really distance = 150; lastGoodDistance = 150; mapScale = 1; [self setViewpointCenter:_player.position]; [_mapLayer addChild:_tileMap]; [self addChild:_mapLayer z:-1]; self.isTouchEnabled = YES; } return self; } And here's the SceneManager code for replacing scenes: +(void) goGameScene { CCLayer *gameLayer = [GameScene node]; [SceneManager go:gameLayer:[GameHUD node]]; } //this is what every call looks like besides the GameScene one above +(void) goLevelSelect { [SceneManager go:[LevelSelect node]:nil]; } +(void) go:(CCLayer *)layer: (CCLayer *)hudLayer { CCDirector *director = [CCDirector sharedDirector]; CCScene *newScene = [SceneManager wrap:layer:hudLayer]; if ([director runningScene]) { [director replaceScene:newScene]; } else { [director runWithScene:newScene]; } } +(CCScene *) wrap:(CCLayer *)layer: (CCLayer *)hudLayer { CCScene *newScene = [CCScene node]; [newScene addChild: layer]; if (hudLayer != nil) { [newScene addChild: hudLayer z:1]; } return newScene; } Any ideas why I'm getting these fatal artifacts? I'm hoping this isn't considered too localized since it basically combines 3 tutorials that anyone could end up following. (Ray Wenderlich Animations, Tim Roadley Scene Manager, Pan and Zoom with Tiled Maps.

• Retrieving recent tweets using LINQ

  - by brian_ritchie

  There are a few different APIs for accessing Twitter from .NET.  In this example, I'll use linq2twitter.  Other APIs can be found on Twitter's development site. First off, we'll use the LINQ provider to pull in the recent tweets. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: public static Status[] GetLatestTweets(string screenName, int numTweets) 2: { 3: try 4: { 5: var twitterCtx = new LinqToTwitter.TwitterContext(); 6: var list = from tweet in twitterCtx.Status 7: where tweet.Type == StatusType.User && 8: tweet.ScreenName == screenName 9: orderby tweet.CreatedAt descending 10: select tweet; 11: // using Take() on array because it was failing against the provider 12: var recentTweets = list.ToArray().Take(numTweets).ToArray(); 13: return recentTweets; 14: } 15: catch 16: { 17: return new Status[0]; 18: } 19: } Once they have been retrieved, they would be placed inside an MVC model. Next, the tweets need to be formatted for display. I've defined an extension method to aid with date formatting: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: public static class DateTimeExtension 2: { 3: public static string ToAgo(this DateTime date2) 4: { 5: DateTime date1 = DateTime.Now; 6: if (DateTime.Compare(date1, date2) >= 0) 7: { 8: TimeSpan ts = date1.Subtract(date2); 9: if (ts.TotalDays >= 1) 10: return string.Format("{0} days", (int)ts.TotalDays); 11: else if (ts.Hours > 2) 12: return string.Format("{0} hours", ts.Hours); 13: else if (ts.Hours > 0) 14: return string.Format("{0} hours, {1} minutes", 15: ts.Hours, ts.Minutes); 16: else if (ts.Minutes > 5) 17: return string.Format("{0} minutes", ts.Minutes); 18: else if (ts.Minutes > 0) 19: return string.Format("{0} mintutes, {1} seconds", 20: ts.Minutes, ts.Seconds); 21: else 22: return string.Format("{0} seconds", ts.Seconds); 23: } 24: else 25: return "Not valid"; 26: } 27: } Finally, here is the piece of the view used to render the tweets. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: <ul class="tweets"> 2: <% 3: foreach (var tweet in Model.Tweets) 4: { 5: %> 6: <li class="tweets"> 7: <span class="tweetTime"><%=tweet.CreatedAt.ToAgo() %> ago</span>: 8: <%=tweet.Text%> 9: </li> 10: <%} %> 11: </ul>

• Profile System: User share the same id

  - by Malcolm Frexner

  I have a strange effect on my site when it is under heavy load. I randomly get the properties of other users settings. I have my own implementation of the profile system so I guess I can not blame the profile system itself. I just need a point to start debugging from. I guess there is a cookie-value that maps to an Profile entry somewhere. Is there any chance to see how this mapping works? Here is my profile provider: using System; using System.Text; using System.Configuration; using System.Web; using System.Web.Profile; using System.Collections; using System.Collections.Specialized; using B2CShop.Model; using log4net; using System.Collections.Generic; using System.Diagnostics; using B2CShop.DAL; using B2CShop.Model.RepositoryInterfaces; [assembly: log4net.Config.XmlConfigurator()] namespace B2CShop.Profile { public class B2CShopProfileProvider : ProfileProvider { private static readonly ILog _log = LogManager.GetLogger(typeof(B2CShopProfileProvider));

• $_POST data returns empty when headers are > POST_MAX_SIZE

  - by Jared

  Hi Hopefully someone here might have an answer to my question. I have a basic form that contains simple fields, like name, number, email address etc and 1 file upload field. I am trying to add some validation into my script that detects if the file is too large and then rejects the user back to the form to select/upload a smaller file. My problem is, if a user selects a file that is bigger than my validation file size rule and larger than php.ini POST_MAX_SIZE/UPLOAD_MAX_FILESIZE and pushes submit, then PHP seems to try process the form only to fail on the POST_MAX_SIZE settings and then clears the entire $_POST array and returns nothing back to the form. Is there a way around this? Surely if someone uploads something than the max size configured in the php.ini then you can still get the rest of the $_POST data??? Here is my code. <?php function validEmail($email) { $isValid = true; $atIndex = strrpos($email, "@"); if (is_bool($atIndex) && !$atIndex) { $isValid = false; } else { $domain = substr($email, $atIndex+1); $local = substr($email, 0, $atIndex); $localLen = strlen($local); $domainLen = strlen($domain); if ($localLen < 1 || $localLen > 64) { // local part length exceeded $isValid = false; } else if ($domainLen < 1 || $domainLen > 255) { // domain part length exceeded $isValid = false; } else if ($local[0] == '.' || $local[$localLen-1] == '.') { // local part starts or ends with '.' $isValid = false; } else if (preg_match('/\\.\\./', $local)) { // local part has two consecutive dots $isValid = false; } else if (!preg_match('/^[A-Za-z0-9\\-\\.]+$/', $domain)) { // character not valid in domain part $isValid = false; } else if (preg_match('/\\.\\./', $domain)) { // domain part has two consecutive dots $isValid = false; } else if (!preg_match('/^(\\\\.|[A-Za-z0-9!#%&`_=\\/$\'*+?^{}|~.-])+$/', str_replace("\\\\","",$local))) { // character not valid in local part unless // local part is quoted if (!preg_match('/^"(\\\\"|[^"])+"$/', str_replace("\\\\","",$local))) { $isValid = false; } } } return $isValid; } //setup post variables @$name = htmlspecialchars(trim($_REQUEST['name'])); @$emailCheck = htmlspecialchars(trim($_REQUEST['email'])); @$organisation = htmlspecialchars(trim($_REQUEST['organisation'])); @$title = htmlspecialchars(trim($_REQUEST['title'])); @$phone = htmlspecialchars(trim($_REQUEST['phone'])); @$location = htmlspecialchars(trim($_REQUEST['location'])); @$description = htmlspecialchars(trim($_REQUEST['description'])); @$fileError = 0; @$phoneError = ""; //setup file upload handler $target_path = 'uploads/'; $filename = basename( @$_FILES['uploadedfile']['name']); $max_size = 8000000; // maximum file size (8mb in bytes) NB: php.ini max filesize upload is 10MB on test environment. $allowed_filetypes = Array(".pdf", ".doc", ".zip", ".txt", ".xls", ".docx", ".csv", ".rtf"); //put extensions in here that should be uploaded only. $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); // Get the extension from the filename. if(!is_writable($target_path)) die('You cannot upload to the specified directory, please CHMOD it to 777.'); //Check if we can upload to the specified upload folder. //display form function function displayForm($name, $emailCheck, $organisation, $phone, $title, $location, $description, $phoneError, $allowed_filetypes, $ext, $filename, $fileError) { //make $emailCheck global so function can get value from global scope. global $emailCheck; global $max_size; echo '<form action="geodetic_form.php" method="post" name="contact" id="contact" enctype="multipart/form-data">'."\n".

one would be the safest as it would grow with the PHP release being used. You could also flip that array around when needed to tie timezones to city names.

• ruby regex, parsing html

  - by danwoods

  Hello all, I'm trying to parse some returned html to look for currently playing movies. The pattern I'm trying to match looks like: <span dir=ltr>Clash of the Titans</span> Of which there are several in the returned html. (the html is huge, I've posted a sample at the bottom) I'm trying get an array of the movie titles with the following command: titles = listings_html.split(/(<span dir=ltr>).*(<\/span>)/) But I'm not getting the results I'm expecting. Can anyone see a problem with my approach or regex? Returned html (I believe the 'markdown'formating will render the some of the html, but this is just an example): <script>window.gbar={};(function(){function h(a,b,d){var c="on"+b;if(a.addEventListener)a.addEventListener(b,d,false);else if(a.attachEvent)a.attachEvent(c,d);else{var f=a[c];a[c]=function(){var e=f.apply(this,arguments),g=d.apply(this,arguments);return

• AngularJS databinding

  - by user3652865

  How can I add multiple values to one object in an Array. I am having Environment and Cluster, I am able to assign multiple clusters to one environment. Now I want to add application name to this environment and cluster pair. I am having page called "Add Application". Here I am using select menu to for environment and Cluster. My first question is, when I select environment then want to show only those clusters which are assigned to that environment name. And assign application name to that pair.
