• Transform between two 3d cartesian coordinate systems

  - by Pris

  I'd like to know how to get the rotation matrix for the transformation from one cartesian coordinate system (X,Y,Z) to another one (X',Y',Z'). Both systems are defined with three orthogonal vectors as one would expect. No scaling or translation occurs. I'm using OpenSceneGraph and it offers a Matrix convenience class, if it makes finding the matrix easier: http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00403.html.

• Advice for beginner programmer

  - by user3461957

  I am beginner in software development. I noticed when I try to learn one technology let's say .NET I loose my grip over other for example Java. I thought it would be better to concentrate on one technology either Java or .NET to make significant advancement and be an expert, because they can be many details which one can ignore when keeps on changing between technologies. Is my decision right? Do experts choose this approach? Update: Should I pursue my career knowing one technology or not?

• Do MORE with WebCenter

  - by Michael Snow

  WEBCAST THURSDAY!! 03/22/12 Do you need to lower costs? Raise Productivity? Foster Innovation? Improve Online Engagement? But you’re still stuck with Documentum? Step away from the ledge – there is hope – let us help you. Top 4 Content Imperatives · Lower Costs - Reduce labor, maintenance fees, storage and electrical consumption · Raise Productivity - Automation and integration, communication, findability · Foster Innovation - Enable collaboration, expertise location · Improve Online Engagement – enable user-driven, dynamic marketing initiatives With the coming technology wave we see four content imperatives. Every organization has had to reduce costs, cost cutting has become a way of life. Everyone is working three jobs as positions are eliminated. And so we have to reduce labor, reduce maintenance, and reduce money we are wasting on things like storing content that is redundant or no longer useful. We also, to fill that gap, need to raise productivity. Knowledge workers represent the fastest growing segment of the workforce, accounting for 40%-75% of the employees at organizations in sectors like financial services, life sciences, healthcare and retail.  What’s more, their wages total 18 percent of the United States GDP. And so we can’t afford information systems that don’t let our top performers be the best they can be. We look to automate the content processes, provide ways to integrate that content into our processes, provide communication to make decisions, and to make content more findable so people can make the right decision and move the process forward. And really to get ourselves out of the current financial status, we can only cut costs so far. We have to innovate out of economic tough times – to find new products and new markets. And to enable the innovation process, we have to enable collaboration and expertise location. So much of innovation is about building on innovations that have come before. To solve problems, we have to be able to find what our organization has already created. We find that problems we need to solve have already been solved if we can find the right document, the right person. So we have to provide systems that enable us to stand on the shoulders of our organization’s accomplishments. Good content drives great marketing. Online engagement is growing as an absolute necessity for modern growing marketing organizations that require the business users be enabled for dynamic marketing content creation, updates and targeted content creation and management. Unfortunately – if you are currently stuck with Documentum, you are really lacking in your Web Experience Management capabilities. Documentum previously used FatWire for web publishing. Now FatWire is part of Oracle. Oracle provides powerful web engagement capabilities: Increase sales and loyalty by optimizing online engagement Create, manage and moderate contextually relevant, targeted and interactive online experiences Optimize customer engagement across, web, mobile and social channels Manage large scale multichannel global online presence with integration to enterprise applications Enable business users to control their content and make their own updates Publish content from native files – enable navigation of project documents, procedures, policy information Enable content display and updates from existing web applications – one click to drag and drop content management functionality So you get the ability to self-publish information and make it navigable, to move the process of publishing from IT to business users, and the ability to address a whole new area of user engagement with web experience management. So… if you are still stuck with Documentum and don’t know what to do – contact us – not only will Oracle help you step away from the ledge, but also with the MoveOff Documentum program, we are offering you a way – trade-in your Documentum licenses for a 100% credit on Oracle WebCenter. How’s that for a nice bonus? It’s time to stop maintaining Documentum, and to start innovating with Oracle WebCenter. Learn More Here! To learn more about what Oracle WebCenter can offer you today – join us for a webcast – your eyes will be opened to all that’s possible. Do More with WebCenter: Extend Beyond Content Management

• Best way to transfer files across unstable LAN?

  - by JamesTheAwesomeDude

  This is very similar to Question 326211, but in this case, the LAN is an unstable Wi-Fi connection. I need to transfer about 11 GiB of files between two computers, both running Linux (although one may be rebooted into Windows.) Their connection is both slow and unstable (due to Linux's awful Wi-Fi support,) but removable media (such as a flash drive or external hard drive) is not an option at this time. Right now, I'm slowly transferring the files, one by one, across SFTP, but I have to reconnect each computer approximately every 90 seconds, and the computers are not very close to each other, so this is not feasible. This is not a duplicate of Question 30186; that one specifically concerns Windows 7, and all the proposed solutions involve closed-source, Windows-only programs (which are all spyware IMHO, and are all off the table even if I trusted them - one of the computers is Linux-only.)

• Recover Time Machine partition that turned MBR only instead of GUID

  - by alex

  I have one drive that has a NTFS partition, a TimeMachine partition (I guess HFS+) and empty space. The other day, I did one partition more from Windows 8 (bootcamp) and since then, I can't see the TimeMachine one from OSX, I can see it from Windows though. The problem is that TimeMachine uses a file system that Windows cannot browse, only shows some folders and I need to recover this partition because I have to use it to backup my Mac. On OSX I can only see the NTFS partition and the other one appears unmounted and it's impossible to mount. I've come to the conclusion that something has happened to the partition table. With TestDisk it shows that it's MBR only when I think it should be GUID: And pressing p shows that it's FDisk_partition_scheme and the TimeMachine one appears as Windows_NTFS. I found this thread that is similar to what it's happening to me: Adding NTFS partition to disk in Windows makes HFS+ partition on same disk invisible in Mac OS X

• DNS hijack - prevention tips

  - by user578359

  Hi there, Over the weekend it looks like the DNS was hijacked on two of my domains. My set up is I have the sites registered on 1and1.co.uk, with dns nameservers pointing to Hostgator in the US where the sites are hosted. I also had cloudflare CDN running on the sites (via hostgator cpanel). My question is any ideas as to how this happened, and how I could either monitor it so I know if it occurs again, or strengthen the set up/service to minimise the risk. History: I received a ping from my site monitoring service that the sites were down. When I checked the sites were up so I assumed it was local to the monitoring service I received a ping last night the sites were up When I checked, one site was redirecting to download-manual.com (and checking that URL now, the home page is not the same as the one I saw, so they too may have been hijacked/hacked) The other site URL remained the same but had one of those standard site search pages which bounce you off to either phishing or paid for search sites I notified Hostgator who told me Cloudflare or 1and1 were the issue. I removed cloudflare, and contacted both them and hostgator, and am awaiting a response, but am not holding my breath. Is this common? I've never heard of this or come across this before. It's pretty scary that this can happen so easily. Appreciate any input. **Update: I've now spoken to support at 1and1, Hostgator, and Cloudflare, and each one claims it has nothing to do with them, and must be one of the others. Larry, curly, moe.

• Increasing deadlocks with NoLock

  - by Dave Ballantyne

  One on my personnel pet issues is with inappropriate use of the NOLOCK hint (and read uncommitted) .  Dont get me wrong, I have used it in exceptional circumstances , but as a general statement it is a bad thing.  Mostly , when NOLOCK, is used the discussion is around a single statement,  “it runs faster with nolock for XYZ reason”,  however ,IMO, this is quite a shorted sighted view.  What about the Transaction ? What about other concurrent users ?  What is good for one statement in isolation , does not mean that it is good for the system as a whole.  I have seen on a number of occasions deadlocks happen, when tasks that would of(and should of) be blocked continue to execute, only for a deadlock to occur at a later data writing (INSERT,UPDATE,DELETE) statement.  Writers will block writers regardless of isolation level. By Way of (fairly contrived ) example , lets generate some dummy tables and populate with some data drop table a go drop table b go Create Table a ( col1 integer ) go insert into a values(1) insert into a values(2) go Create Table b ( col1 integer ) go insert into b values(1) insert into b values(2) go   Now make two connections. In connection one execute set transaction isolation level read committed BEGIN TRAN Select * from a Select * from b delete from a In connection two execute set transaction isolation level read committed BEGIN TRAN Select * from a Select * from b delete from b Right now the ‘select from a’ in connection two is being blocked by the ‘delete from a’ in connection one.  This is ,IMO, quite a healthy and natural thing to be happening , some see this as a ‘slow down’, a drop in performance.  So, lets reach for our ‘NOLOCK’ magic pill.  Cancel the blocked query and ROLLBACK both transactions, then in connection one execute set transaction isolation level read uncommitted BEGIN TRAN Select * from a Select * from b delete from b and then in connection two execute set transaction isolation level read uncommitted BEGIN TRAN Select * from a Select * from b delete from a We have now solved out performance problem , no more blocking.  Lets finish the work required by the transaction, in connection one , execute delete from a Oh, ‘ performance problem’ again , its now being blocked. Still, lets complete the work in connection two…. delete from b DEADLOCK!!  It is important to be clear about the role of the select statements.  They do not participate within the deadlock, but are preventing code executing that would of.   Additionally, without the select readers to block, a deadlock would occur on the deletes with READ COMMITTED. Naturally, other isolation levels will exhibit different behaviour as to where and when they will and wont block,  and I would encourage you to read BOL and satisfy yourself that you really do NEED to NOLOCK.

• What are the tools required to build a compiler?

  - by kevin

  What are the various tools that are required to build a compiler for a particular programming language, say C? I want to know how each part of the compiler works. So, I am trying to use all the existing tools like loader, linker, etc, and combine them together to build one compiler (or can just say "compiling a compiler"). Can any one list out all such tools that are required to build a fully functional one?

• Securing an ADF Application using OES11g: Part 1

  - by user12587121

  Future releases of the Oracle stack should allow ADF applications to be secured natively with Oracle Entitlements Server (OES). In a sequence of postings here I explore one way to achive this with the current technology, namely OES 11.1.1.5 and ADF 11.1.1.6. ADF Security Basics ADF Bascis The Application Development Framework (ADF) is Oracle’s preferred technology for developing GUI based Java applications.  It can be used to develop a UI for Swing applications or, more typically in the Oracle stack, for Web and J2EE applications.  ADF is based on and extends the Java Server Faces (JSF) technology.  To get an idea, Oracle provides an online demo to showcase ADF components. ADF can be used to develop just the UI part of an application, where, for example, the data access layer is implemented using some custom Java beans or EJBs.  However ADF also has it’s own data access layer, ADF Business Components (ADF BC) that will allow rapid integration of data from data bases and Webservice interfaces to the ADF UI component.   In this way ADF helps implement the MVC  approach to building applications with UI and data components. The canonical tutorial for ADF is to open JDeveloper, define a connection to a database, drag and drop a table from the database view to a UI page, build and deploy.  One has an application up and running very quickly with the ability to quickly integrate changes to, for example, the DB schema. ADF allows web pages to be created graphically and components like tables, forms, text fields, graphs and so on to be easily added to a page.  On top of JSF Oracle have added drag and drop tooling with JDeveloper and declarative binding of the UI to the data layer, be it database, WebService or Java beans.  An important addition is the bounded task flow which is a reusable set of pages and transitions.   ADF adds some steps to the page lifecycle defined in JSF and adds extra widgets including powerful visualizations. It is worth pointing out that the Oracle Web Center product (portal, content management and so on) is based on and extends ADF. ADF Security ADF comes with it’s own security mechanism that is exposed by JDeveloper at development time and in the WLS Console and Enterprise Manager (EM) at run time. The security elements that need to be addressed in an ADF application are: authentication, authorization of access to web pages, task-flows, components within the pages and data being returned from the model layer. One  typically relies on WLS to handle authentication and because of this users and groups will also be handled by WLS.  Typically in a Dev environment, users and groups are stored in the WLS embedded LDAP server. One has a choice when enabling ADF security (Application->Secure->Configure ADF Security) about whether to turn on ADF authorization checking or not: In the case where authorization is enabled for ADF one defines a set of roles in which we place users and then we grant access to these roles to the different ADF elements (pages or task flows or elements in a page). An important notion here is the difference between Enterprise Roles and Application Roles. The idea behind an enterprise role is that is defined in terms of users and LDAP groups from the WLS identity store.  “Enterprise” in the sense that these are things available for use to all applications that use that store.  The other kind of role is an Application Role and the idea is that  a given application will make use of Enterprise roles and users to build up a set of roles for it’s own use.  These application roles will be available only to that application.   The general idea here is that the enterprise roles are relatively static (for example an Employees group in the LDAP directory) while application roles are more dynamic, possibly depending on time, location, accessed resource and so on.  One of the things that OES adds that is that we can define these dynamic membership conditions in Role Mapping Policies. To make this concrete, here is how, at design time in Jdeveloper, one assigns these rights in Jdeveloper, which puts them into a file called jazn-data.xml: When the ADF app is deployed to a WLS this JAZN security data is pushed to the system-jazn-data.xml file of the WLS deployment for the policies and application roles and to the WLS backing LDAP for the users and enterprise roles.  Note the difference here: after deploying the application we will see the users and enterprise roles show up in the WLS LDAP server.  But the policies and application roles are defined in the system-jazn-data.xml file.  Consult the embedded WLS LDAP server to manage users and enterprise roles by going to the domain console and then Security Realms->myrealm->Users and Groups: For production environments (or in future to share this data with OES) one would then perform the operation of “reassociating” this security policy and application role data to a DB schema (or an LDAP).  This is done in the EM console by reassociating the Security Provider.  This blog posting has more explanations and references on this reassociation process. If ADF Authentication and Authorization are enabled then the Security Policies for a deployed application can be managed in EM.  Our goal is to be able to manage security policies for the applicaiton rather via OES and it's console. Security Requirements for an ADF Application With this package tour of ADF security we can see that to secure an ADF application with we would expect to be able to take care of at least the following items: Authentication, including a user and user-group store Authorization for page access Authorization for bounded Task Flow access.  A bounded task flow has only one point of entry and so if we protect that entry point by calling to OES then all the pages in the flow are protected.  Authorization for viewing data coming from the data access layer In the next posting we will describe a sample ADF application and required security policies.

• Five things SSIS should drop

  - by jamiet

  There’s a current SQL Server meme going round entitled Five things SQL Server should drop and, whilst no-one tagged me to write anything, I couldn’t resist doing the same for SQL Server Integration Services. So, without further ado, here are five things that I think should be dropped from SSIS.Data source connectionsSeriously, does anyone use these? I know why they’re there. Someone sat in a meeting back in the early part of the last decade and said “Ooo, Reporting Services and Analysis Services have these things called Data Sources. If we used them in Integration Services then we’d have a really cool integration story.” Errr….no.Web Service TaskDitto. If you want to do anything useful against anything but the simplest of SOAP web services steer well clear of this peculiar SSIS additionActiveX Script TaskAnother task that I suspect has never seen the light of day in a SSIS package. It was billed as a way of running upgraded DTS2000 ActiveX scripts in SSIS – sounds good except for one thing. Anytime one of those scripts would try to talk to the DTS object model (which they all do – otherwise what’s the point) then they will error out. This one has always been a real head scratcher.Slow Changing Dimension wizardI suspect I may get some push back on this one but I’m mentioning it anyway. Some people like the SCD wizard; I am not one of those people! Everything that the SCD component does can easily be reproduced using other components and from a performance point of view its much more beneficial to use those alternatives.Multifile Connection ManagerImagining buying a house that came with a set of keys that didn’t open any of the doors. Sounds ridiculous right? How about a SSIS Connection Manager that doesn’t get used by any of the tasks or components. Ah, that’ll be the Multifile Connection Manager then!Comments are of course welcome. Diatribes are assumed :)@Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Travelling MVP #2: Community event at Bucharest, Romania

  - by DigiMortal

  My second trip was to DevReach with two stops. My first stop was at Bucharest where I met with my friend Dimitar Georgiev who is one of authors of Gym Realm service. Romanian MVP Andrei Ignat was our host there and organized meeting with local community guys. With me – it was first time in my life – was one more guy from Estonia visiting DevReach and he made the whole trip with me. Bucharest We arrived to Bucharest 29.09 at night. We stayed at Hotel Michelangelo. It’s small hotel with nice rooms, free WiFi and very good service. Although my room was on the first floor there was no street noise. We visited one restaurant that offers national cuisine and it was really great. Next day we went out with local guys and had some beers in “old town”. Bucharest “old town” is nice and cozy. There are many bars open and I am sure everybody will find there some very okay place. After supper we visited one warm karaoke bar where we had beers with local guys. Andrei Ignat – karaoke star Agu Suur and Andrei Ion Rinea enjoying karaoke and tequila Community event Next day we had community event. I made my session about ASP.NET Web API and Dimitar told about how to port ASP.NET web applications to cloud environment. Sessions were held at study class of one local company. Dimitar Georgiev speaking about porting web apps to Windows Azure. As it was usual community evening and not some bigger event there were about 12 guys attending from Bucharest. There were both IT-PROs and developers and one nice thing about Bucharest community is that they are listening to you very well and they ask questions if something is unclear or if you slide over from topic they are interested in. Okay, we tried to keep up good tempo so people stay awake and I think we succeeded. After sessions we went all together to local Piranha pub that was near event venue. We had some beers with local guys and talked with them on different technology topics. It was another good and interesting evening at Bucharest. I want to go back there for sure. As it was my first trip to Bucharest and mostly I gathered experiences I think my next community trip there will be way stronger. I take it as a challenge. Plus – I have there some new friends and I want to meet them too – be it community event or not. :)

• Finding an A* heuristic for a directed graph

  - by Janis Peisenieks

  In a previous question, I asked about finding a route (or path if you will) in a city. That is all dandy. The solution I chose was with the A* algorithm, which really seems to suit my needs. What I find puzzling is heuristic. How do I find one in an environment without constant distance between 2 nodes? Meaning, not every 2 nodes have the same distance between them. What I have is nodes (junctures), streets with weight (which may also be one-way), a start/finish node (since the start and end is always in the same place) and a goal node. In an ordinary case, I would just use the same way I got to goal to go back, but since one of the streets could have been a one-way, that may not be possible. The main question How do I find a heuristic in a directed graph?

• Is there a language or design pattern that allows the *removal* of object behavior or properties in a class hierarchy?

  - by Sebastien Diot

  A well-know shortcoming of traditional class hierarchies is that they are bad when it comes to model the real world. As an example, trying to represent animals species with classes. There are actually several problems when doing that, but one that I never saw a solution to is when a sub-class "looses" a behavior or properties that was defined in a super-class, like a penguin not being able to fly (there are probably better examples, but that's the first one that comes to my mind, having seen "Madagascar 2" recently). On the one hand, you don't want to define for every property and behavior some flag that specifies if it is at all present, and check it every time before accessing that behavior or property. You would just like to say that birds can fly, simply and clearly, in the Bird class. But then it would be nice if one could define "exceptions" afterward, without having to use some horrible hacks everywhere. This often happens when a system has been productive for a while. You suddenly find an "exception" that doesn't fit in the original design at all, and you don't want to change a large portion of your code to accommodate it. So, is there some language or design patterns that can cleanly handle this problem, without requiring major changes to the "super-class", and all the code that uses it? Even if a solution only handle a specific case, several solutions might together form a complete strategy. [EDIT] Forgot about the Liskov Substitution Principle. That is why you can't do it. Assuming you define "traits/interfaces" for all major "feature groups", you can freely implement traits in different branches of the hierarchy, like the Flying trait could be implemented by Birds, and some special kind of squirrels and fish. So my question could amount to "How could I un-implement a trait?" If your super-class is a Java Serializable, you have to be one too, even if there is no way for you to serialize your state, for example if you contained a "Socket". So one way to do it is to always define all your traits in pair from the start: Flying and NotFlying (which would throw UnsupportedOperationExceiption, if not checked against). The Not-trait would not define any new interface, and could be simply checked for. Sounds like a "cheap" solution, in particular if used from the start.

• Unity Dash to search only in Documents

  - by bioShark

  I have a document (LibreOffice Calc Spreadsheet) which is in my ~/Documents folder. However, I have the same file (older version of it) on a mounted drive. In the past few weeks I have opened the file from both my ~/Documents folder and from the mounted drive. However, the latest version is the one from ~/Documents. When I open the Dash and look in the documents lens, of course I will find my file twice there. One from the mounted disk and one from ~/Documents. But I don't know which one is which. So, my question is: How can I limit the document lens to look for documents only from my /home. Or to exclude mounted disks from the search. Thanks. I use Ubuntu 12.04.

• Ip doesn't change when switching networks, although automatic ip is set. Cause of the issue known

  - by Julio Acevedo

  I have two routers at my house. Both of them have DCHP server enabled. One of them is 192.168.1.1 and gives adresses from 192.168.1.2 to 192.168.1.32 The other one is 192.168.1.50 and gives adresses from 192.168.1.51 to 192.168.1.99 The problem is that I only have internet access in one because my ip is 192.168.1.7, and when I switch to the other one, the ip remains 192.168.1.7, even though I have automatically get a ip adress in Ipv4. When I manually change my ip to one in the range allowed by the router, I can browse the internet. Any ideas how to solve this? Thank you.

  I like to print on stationery with a pre-printed letterhead using the Preview.app and a duplex-capable HP PostScript (Color Laserjet 4700) printer. One would think that pre-printed stationery could be placed into one of the trays and then printed on front and reverse side. Unfortunately, the print dialog handles one and two-paged documents differently: the stationery needs to be placed differently into the tray if the document contains one page versus when it contains two pages. This is not obvious when printing on plain paper but becomes obvious once you mark, say, the upper left front corner of pages and then print different documents on them. I checked the PostScript code generated and indeed it is different for one versus two-page documents with respect to duplex printing, probably causing the difference in paper handling. Obviously this makes it difficult to print pre-printed stationery in duplex mode. I expected others to have stumbled upon this but could not find specific help so far. Any ideas? This is on OS X 10.6 and I checked two different printers.

• Is there a better term than "smoothness" or "granularity" to describe this language feature?

  - by Chris

  One of the best things about programming is the abundance of different languages. There are general purpose languages like C++ and Java, as well as little languages like XSLT and AWK. When comparing languages, people often use things like speed, power, expressiveness, and portability as the important distinguishing features. There is one characteristic of languages I consider to be important that, so far, I haven't heard [or been able to come up with] a good term for: how well a language scales from writing tiny programs to writing huge programs. Some languages make it easy and painless to write programs that only require a few lines of code, e.g. task automation. But those languages often don't have enough power to solve large problems, e.g. GUI programming. Conversely, languages that are powerful enough for big problems often require far too much overhead for small problems. This characteristic is important because problems that look small at first frequently grow in scope in unexpected ways. If a programmer chooses a language appropriate only for small tasks, scope changes can require rewriting code from scratch in a new language. And if the programmer chooses a language with lots of overhead and friction to solve a problem that stays small, it will be harder for other people to use and understand than necessary. Rewriting code that works fine is the single most wasteful thing a programmer can do with their time, but using a bazooka to kill a mosquito instead of a flyswatter isn't good either. Here are some of the ways this characteristic presents itself. Can be used interactively - there is some environment where programmers can enter commands one by one Requires no more than one file - neither project files nor makefiles are required for running in batch mode Can easily split code across multiple files - files can refeence each other, or there is some support for modules Has good support for data structures - supports structures like arrays, lists, and especially classes Supports a wide variety of features - features like networking, serialization, XML, and database connectivity are supported by standard libraries Here's my take on how C#, Python, and shell scripting measure up. Python scores highest. Feature C# Python shell scripting --------------- --------- --------- --------------- Interactive poor strong strong One file poor strong strong Multiple files strong strong moderate Data structures strong strong poor Features strong strong strong Is there a term that captures this idea? If not, what term should I use? Here are some candidates. Scalability - already used to decribe language performance, so it's not a good idea to overload it in the context of language syntax Granularity - expresses the idea of being good just for big tasks versus being good for big and small tasks, but doesn't express anything about data structures Smoothness - expresses the idea of low friction, but doesn't express anything about strength of data structures or features Note: Some of these properties are more correctly described as belonging to a compiler or IDE than the language itself. Please consider these tools collectively as the language environment. My question is about how easy or difficult languages are to use, which depends on the environment as well as the language.
