  • TLS/SSL and .NET Framework 4.0

    The Secure Socket Layer is now essential for the secure exchange of digital data, and is most generally used within the HTTPS protocol. .NET now provides the Windows Communication Foundation (WCF) to implement secure communications directly. Matteo explains the TLS/SSL protocol, and takes a hands-on approach to investigate the SslStream class to show how to implement a secure communication channel

  • Is the TCP protocol good enough for real-time multiplayer games?

    - by kevin42
    Back in the day, TCP connections over dialup/ISDN/slow broadband resulted in choppy, laggy games because a single dropped packet resulted in a resync. That meant a lot of game developers had to implement their own reliability layer on top of UDP, or they used UDP for messages that could be dropped or received out of order, and used a parallel TCP connection for information that must be reliable. Given the average user has faster network connections now, can a real time game such as an FPS give good performance over a TCP connection?

  • Understanding the levels of computing

    - by RParadox
    Sorry, for my confused question. I'm looking for some pointers. Up to now I have been working mostly with Java and Python on the application layer and I have only a vague understanding of operating systems and hardware. I want to understand much more about the lower levels of computing, but it gets really overwhelming somehow. At university I took a class about microprogramming, i.e. how processors get hard-wired to implement the ASM codes. Up to now I always thought I wouldn't get more done if learned more about the "low level". One question I have is: how is it even possible that hardware gets hidden almost completely from the developer? Is it accurate to say that the operating system is a software layer for the hardware? One small example: in programming I have never come across the need to understand what L2 or L3 Cache is. For the typical business application environment one almost never needs to understand assembler and the lower levels of computing, because nowadays there is a technology stack for almost anything. I guess the whole point of these lower levels is to provide an interface to higher levels. On the other hand I wonder how much influence the lower levels can have, for example this whole graphics computing thing. So, on the other hand, there is this theoretical computer science branch, which works on abstract computing models. However, I also rarely encountered situations, where I found it helpful thinking in the categories of complexity models, proof verification, etc. I sort of know, that there is a complexity class called NP, and that they are kind of impossible to solve for a big number of N. What I'm missing is a reference for a framework to think about these things. It seems to me, that there all kinds of different camps, who rarely interact. The last few weeks I have been reading about security issues. Here somehow, much of the different layers come together. Attacks and exploits almost always occur on the lower level, so in this case it is necessary to learn about the details of the OSI layers, the inner workings of an OS, etc.

  • Crash when using datablocks

    - by scorcher24
    I have really throughly searched the net and could not find any solution for this so I ask for help here. Anyway, I have this datablock in datablocks.cs: datablock t2dSceneObjectDatablock(EnemyShipConfig) { canSaveDynamicFields = "1"; Layer = "3"; size = "64 64"; CollisionActiveSend = "1"; CollisionActiveReceive = "1"; CollisionCallback = true; CollisionLayers = "3"; CollisionDetectionMode = "POLYGON"; CollisionPolyList = "0.00 -0.791 0.756 0.751 -0.746 0.732"; UsesPhysics = "0"; Rotation = "-90"; WorldLimitMode = "KILL"; WorldLimitMax = "880 360"; WorldLimitMin = "-765 -436"; minFireRate = "2000"; maxFireRate = "1200"; laserSpeed = "800"; minSpeed = "100"; maxSpeed = "150"; }; This is an exact reproduction of an object that I have manually edited in the editor. So far, I just used clone() to get as many enemies as I need, while it was out of sight. It is a r-type style shooter, so I need a variable amount of enemies. Since clone() spams my log, I decided to use datablocks, since it is also more flexible. That's what I get when I use clone(): Con::execute - 0 has no namespace: onRemoveFromScene However, once spawning begins, my game freezes and crashes: function SpawnEnemy() { //%spawnedEnemy = EnemyShipMaster.clone(true); %spawnedEnemy = new t2dStaticSprite() { class = "EnemyShip"; sceneGraph = $global_sceneGraph; datablock = "EnemyShipConfig"; imageMap = "starshipImageMap"; layer = 3; }; %speed = getRandom(%spawnedEnemy.minSpeed, %spawnedEnemy.maxSpeed); %y = getRandom(-320, 320); // Set Properties %spawnedEnemy.setPositionX(700); %spawnedEnemy.setPositionY(%y); %spawnedEnemy.setVisible(true); %spawnedEnemy.setLinearVelocityX( -%speed ); %spawnedEnemy.setTimerOn( getRandom( %spawnedEnemy.maxFireRate, %spawnedEnemy.minFireRate ) ); } // Definition of $global_sceneGraph from game.cs: $global_sceneGraph = sceneWindow2D.loadLevel(%level); As I said, it works fine when I use clone() (which is commented out here), but my log gets spammed. I really hope someone can shed some light for me, this is driving me crazy.

  • Developer career feeling like going back in time every new job [closed]

    - by komediant
    Is there a good category for this question? My background is bachelor in ICT and for a hobby I am programming already since I was around twelve I think. Started with QBasic, Pascal, C, Java et cetera. Currently I am working for about eight/nine years. Half academics/medical and half company world. A few years ago I started with frameworks and I began with Grails (underlying Spring/Hibernate), which was a heavenly job, very productive and no hassle. My previous job I developed in pure Spring/Hibernate Java, which was a bit more writing annotations and XML and no conventions like Grails. But still, I did like Spring/Hibernate a lot and the professional setup with a developmentstreet, versioning, Jenkins/Sonar, log4j and a good IDE like IntellIJ. It felt quite 'clear' and organised, although I knew Grails which felt a bit more productive. But...at my current job almost half the code is pure servlet, hard coded JDBC (connections handled by yourself), scriptlets in all JSP pages, no service layer, no versioning, no Maven, HTML in DAO-layer, JAR-hell, no hot swap deployment locally, every change you have to deploy and hope it works fine on the server. All local development needs ugly scriptlet tags to check which environment it is running. Et cetera. Now and then developers work over in the evening - I don't - and still lots of issues are not solved and new projects are waiting. I hear the developers complaining, but somehow they feel like what they have now is "advanced" or they are in a sort of comfore zone. The lead developer seems open for new things, but half of the times he says he can implement MVC-framework features himself instead of using what is already out there. So in short, I currently feel like I miss all the modern framework techniques and that the company is going so slow forward. I just work here for two months now. What I do now is also code some partially ugly stuff, but it goes in completely into my nature and I feel uncomfortable with it. Coding something takes long(er) than estimated and my manager complains about why it takes so long and I feel ashamed for myself needing so much time. Where I was used to just writing a query I now build up whole try catch methods. My manager knows my complaints and the developers do so too. There will come a meeting to line out plans for 2013 on technology and the issues I and the company are facing. I am not looking for another job yet, it's close to wehre I live and the economy is fragile. Does anyone else have had this kind of career, like feeling going backwards witch technology? And how did you cope with it?

  • LibGDX - Textures rendering at wrong position

    - by ACluelessGuy
    Update 2: Let me further explain my problem since I think that i didn't make it clear enough: The Y-coordinates on the bottom of my screen should be 0. Instead it is the height of my screen. That means the "higher" i touch/click the screen the less my y-coordinate gets. Above that the origin is not inside my screen, atleast not the 0 y-coordinate. Original post: I'm currently developing a tower defence game for fun by using LibGDX. There are places on my map where the player is or is not allowed to put towers on. So I created different ArrayLists holding rectangles representing a tile on my map. (towerPositions) for(int i = 0; i < map.getLayers().getCount(); i++) { curLay = (TiledMapTileLayer) map.getLayers().get(i); //For all Cells of current Layer for(int k = 0; k < curLay.getWidth(); k++) { for(int j = 0; j < curLay.getHeight(); j++) { curCell = curLay.getCell(k, j); //If there is a actual cell if(curCell != null) { tileWidth = curLay.getTileWidth(); tileHeight = curLay.getTileHeight(); xTileKoord = tileWidth*k; yTileKoord = tileHeight*j; switch(curLay.getName()) { //If layer named "TowersAllowed" picked case "TowersAllowed": towerPositions.add(new Rectangle(xTileKoord, yTileKoord, tileWidth, tileHeight)); // ... AND SO ON If the player clicks on a "allowed" field later on he has the opportunity to build a tower of his coice via a menu. Now here is the problem: The towers render, but they render at wrong position. (They appear really random on the map, no certain pattern for me) for(Rectangle curRect : towerPositions) { if(curRect.contains(xCoord, yCoord)) { //Using a certain tower in this example (left the menu out if(gameControl.createTower("towerXY")) { //RenderObject is just a class holding the Texture and x/y coordinates renderList.add(new RenderObject(new Texture(Gdx.files.internal("TowerXY.png")), curRect.x, curRect.y)); } } } Later on i render it: game.batch.begin(); for(int i = 0; i < renderList.size() ; i++) { game.batch.draw(renderList.get(i).myTexture, renderList.get(i).x, renderList.get(i).y); } game.batch.end(); regards

  • How do you edit the "Preferred Format" settings in Rhythmbox?

    - by skyblue
    In Rhythmbox's Preferences, you can change the "Preferred Format" for Music to MPEG Layer 3 Audio, Ogg Vorbis, FLAC, or MPEG 4 Audio. However, despite there being a Settings button, it does not become enabled for any of these choices. (I have installed all of the gstreamer plugins, but this has made no difference.) So how can you change the "Preferred Format", for example to change the bit rate or the quality setting?

  • Are there new flexible texteditors? [closed]

    - by RParadox
    Vi(m) and Emacs are almost 40 years old. Why are they still the standard, and what attempts have been made at coming up with a new flexible editor? Are there any features which can not be built into vim/emacs? My question is similar to this one: Time to drop Emacs and vi? No one had a suggestion, which surprises me. I would have thought that the core of a texteditor is very small and that people brew their own. Perhaps nobody wants to deal with supporting all the modes? Edit to clarify my question: Instead of writing modes and scripts I ask myself, why there is not a much lightweight project, which lets people custom the editor more directly? Vim has 365395 LOC (C lines all included), Emacs 1.5 million LOC. Why is there a project with say 50k LOC, which is the core, why people can use more freely? Perhaps there is such project, I haven't looked very far. I thought about putting together modules from Vim myself and experimenting with some ideas. The core of editing shouldn't be more than 10k? Vim has a lot optimizations which is really an overkill nowadays. Basically I'm looking for a code base for my own editor and Vi/Emacs are I believe not intended to be used in this way. Bill Joy said the following about vi. http://web.cecs.pdx.edu/~kirkenda/joy84.html The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands. In some sense, its backwards from the kind of thing you'd get from a mouse-oriented thing. I think multiple levels of undo would be wonderful, too. But fundamentally, vi is still ed inside. You can't really fool it. Its like one of those pinatas - things that have candy inside but has layer after layer of paper mache on top. It doesn't really have a unified concept. I think if I were going to go back - I wouldn't go back, but start over again.

  • What interface does python use to implement sockets?

    - by user2738698
    When I programmed in python, I believe I interfaced with the transport layer using sockets. If python was programmed by humans, they must have used an interface that was "lower" than sockets, to provide us with the interface to sockets. I assume firewalls, also programmed by humans, use interfaces of lower layers in the same manner, so is there a way to access such lower layers, in terms of programming?

  • Are there any limitations to using WinRT instead of .Net?

    - by jerrykobes
    From my understanding creating an application that runs on multiple architectures requires virtualization, and virtualization reduces performance since it creates a layer of abstraction. With Windows 8 supporting both Intel and ARM architectures should we expect slower performance with a WinRT app versus a .Net app running on an Intel device? Also, will WinRT support database connectivity and active directory access?

  • Single API Architecture

    - by user1901686
    When people refer to an architecture that involves a single service API that all clients talk to (a client can be an iPad app, etc), what is the "client" for the web app -- is it A) the web browser itself. Thus, the entire app is written in html/css/javascript and ajax calls to the service are made to fetch data and changes are made through javascript or B) you have an MVC-like stack on a server, only instead of the controllers calling to the model layer directly, they call to the service API which return models that are used to render the traditional views or C) something else?

  • Squid + Dans Guardian (simple configuration)

    - by The Digital Ninja
    I just built a new proxy server and compiled the latest versions of squid and dansguardian. We use basic authentication to select what users are allowed outside of our network. It seems squid is working just fine and accepts my username and password and lets me out. But if i connect to dans guardian, it prompts for username and password and then displays a message saying my username is not allowed to access the internet. Its pulling my username for the error message so i know it knows who i am. The part i get confused on is i thought that part was handled all by squid, and squid is working flawlessly. Can someone please double check my config files and tell me if i'm missing something or there is some new option i must set to get this to work. dansguardian.conf # Web Access Denied Reporting (does not affect logging) # # -1 = log, but do not block - Stealth mode # 0 = just say 'Access Denied' # 1 = report why but not what denied phrase # 2 = report fully # 3 = use HTML template file (accessdeniedaddress ignored) - recommended # reportinglevel = 3 # Language dir where languages are stored for internationalisation. # The HTML template within this dir is only used when reportinglevel # is set to 3.

  • BizTalk Server Monitoring &ndash; SharePoint Web Part

    - by SURESH GIRIRAJAN
    I have been worked with customers using BizTalk as shared infrastructure in the enterprise, where we have two or more BizTalk apps running on it for different Business groups. Also these customers are not using BizTalk ESB portal even though they are using BizTalk ESB exception framework. So main issue with all these Business groups are they don’t have visibility into the BizTalk apps running in prod, even though they are using SCOM and other monitoring stuff in place. So I am trying to address few issues I am going to list below and how I try to mitigate them, first one on the list is how to get visibility into prod, how to provision those access to the BizTalk resources with minimal activity and how can we take advantage of the resources we have today. So I was working on creating REST data services for BizTalk RFID a year ago and available on codeplex. I thought to extend that idea to take advantage of BizTalk Data Services available in codeplex. I extended the BizTalk data services I will upload the updated service soon. So let me start thru how my solution works, so first step I am using the BizTalk data service (REST service) which expose most of the BizTalk artifacts as resources such as Applications, Orchestrations, Send ports, Receive ports, Host instances and In process instances etc. BizTalk Server Monitoring – SharePoint Web Part I am hosting the BizTalk data service in IIS with application pool configured to run under BizTalk administrator credentials. So with this setup I am making the service to make accessible anonymous. Next step of this solution I have created a SharePoint Visual web part which consumes the BizTalk data service and display all the BizTalk Application and Platform settings in read only mode. Even though BizTalk data services offers to browse resources as well perform actions like starting, stopping Orchestrations, Send ports, Receive locations, Host instances etc. Host Instances BizTalk Applications BizTalk Running / Suspended Instances So having this BizTalk Monitoring SharePoint web part, will be added to the SharePoint. This eliminates the need for granting access to the BizTalk users explicitly, so when you have BizTalk contractor or BizTalk application user need to have access to the BizTalk environment all the need is have access to the SharePoint website. You can configure the web part point to different end point based on your environment. I am making this as read only as part of this to make easier for the users and in terms of provisioning. This removes the dependency of BizTalk admin at least for viewing the BizTalk application status and errors etc. If we need to make any changes to the BizTalk application then its application owner responsibility to co-ordinate with BizTalk admins. There are options like BizTalk ESB portal, BizTalk 360 etc… but this one of the approach to reduce number of steps required to give access to BizTalk application users and also to maximize the resource we have in enterprise today. Also you can expose this data service thru Azure Service Bus and access from other apps like mobile devices or create a web site hosted in Azure etc. One last thing I have tested only with BizTalk Server 2010 on x64 VM only, but it should work on other version. I will try to upload the code shortly with instructions how to setup etc.… I welcome thoughts and suggestions… Hope this helps….

  • Release Management as Orchestra

    - by ericajanine
    I read an excellent, concise article (http://www.buildmeister.com/articles/software_release_management_best_practices) on the basics of release management practices. In the article, it states "Release Management is often likened to the conductor of an orchestra, with the individual changes to be implemented the various instruments within it." I played in music ensembles for years, so this is especially close to my heart as example. I learned most of my discipline from hours and hours of practice at the hand of a very skilled conductor and leader. I also learned that the true magic in symphonic performance is one where everyone involved is focused on one sound, one goal. In turn, that solid focus creates a sound and experience bigger than just mechanics alone accomplish. In symphony, a conductor's true purpose is to make you, a performer, better so the overall sound and end product is better. The big picture (the performance of the composition) is the end-game, and all musicians in the orchestra know without question their part makes up an important but incomplete piece of that performance. A good conductor works with each section (e.g. group) to ensure their individual pieces are solid. Let's restate: The conductor leads and is responsible for ensuring those pieces are solid. While the performers themselves are doing the work, the conductor is the final authority on when the pieces are ready or not. If not, the conductor initiates the efforts to get them ready or makes the decision to scrap their parts altogether for the sake of an overall performance. Let it sink in, because it's clear--It is not the performer's call if they play their part as agreed, it's the conductor's final call to allow it. In comparison, if a software release manager is a conductor, the only way for that manager to be effective is to drive the overarching process and execution of individual pieces of a software development lifecycle. It does not mean the release manager performs each and every piece, it means the release manager has oversight and influence because the end-game is a successful software enhancin a useable environment. It means the release manager, not the developer or development manager, has the final call if something goes into a software release. Of course, this is not a process of autocracy or dictation of absolute rule, it's cooperative effort. But the release manager must have the final authority to make a decision if something is ready to be added to the bigger piece, the overall symphony of software changes being considered for package and release. It also goes without saying a release manager, like a conductor, must have full autonomy and isolation from other software groups. A conductor is the one on the podium waving a little stick at the each section and cueing them for their parts, not yelling from the back of the room while also playing a tuba and taking direction from the horn section. I have personally seen where release managers are relegated to being considered little more than coordinators, red-tapers to "satisfy" the demands of an audit group without being bothered to actually respect all that a release manager gives a group willing to employ them fully. In this dysfunctional scenario, development managers, project managers, business users, and other stakeholders have been given nearly full clearance to demand and push their agendas forward, causing a tail-wagging-the-dog scenario where an inherent conflict will ensue. Depending on the strength, determination for peace, and willingness to overlook a built-in expectation that is wrong, the release manager here must face the crafted conflict head-on and diffuse it as quickly as possible. Then, the release manager must clearly make a case why a change cannot be released without negative impact to all parties involved. If a political agenda is solely driving a software release, there IS no symphony, there is no "software lifecycle". It's just out-of-tune noise. More importantly, there is no real conductor. Sometimes, just wanting to make a beautiful sound is not enough. If you are a release manager, are you freed up enough to move, to conduct the sections of software creation to ensure a solid release performance is possible? If not, it's time to take stock in what your role actually is and see if that is what you truly want to achieve in your position. If you are, then you can successfully build your career and that of the people in your groups to create truly beautiful software (music) together.

  • How Exactly Is One Linux OS “Based On” Another Linux OS?

    - by Jason Fitzpatrick
    When reviewing different flavors of Linux, you’ll frequently come across phrases like “Ubuntu is based on Debian” but what exactly does that mean? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader PLPiper is trying to get a handle on how Linux variants work: I’ve been looking through quite a number of Linux distros recently to get an idea of what’s around, and one phrase that keeps coming up is that “[this OS] is based on [another OS]“. For example: Fedora is based on Red Hat Ubuntu is based on Debian Linux Mint is based on Ubuntu For someone coming from a Mac environment I understand how “OS X is based on Darwin”, however when I look at Linux Distros, I find myself asking “Aren’t they all based on Linux..?” In this context, what exactly does it mean for one Linux OS to be based on another Linux OS? So, what exactly does it mean when we talk about one version of Linux being based off another version? The Answer SuperUser contributor kostix offers a solid overview of the whole system: Linux is a kernel — a (complex) piece of software which works with the hardware and exports a certain Application Programming Interface (API), and binary conventions on how to precisely use it (Application Binary Interface, ABI) available to the “user-space” applications. Debian, RedHat and others are operating systems — complete software environments which consist of the kernel and a set of user-space programs which make the computer useful as they perform sensible tasks (sending/receiving mail, allowing you to browse the Internet, driving a robot etc). Now each such OS, while providing mostly the same software (there are not so many free mail server programs or Internet browsers or desktop environments, for example) differ in approaches to do this and also in their stated goals and release cycles. Quite typically these OSes are called “distributions”. This is, IMO, a somewhat wrong term stemming from the fact you’re technically able to build all the required software by hand and install it on a target machine, so these OSes distribute the packaged software so you either don’t need to build it (Debian, RedHat) or they facilitate such building (Gentoo). They also usually provide an installer which helps to install the OS onto a target machine. Making and supporting an OS is a very complicated task requiring a complex and intricate infrastructure (upload queues, build servers, a bug tracker, and archive servers, mailing list software etc etc etc) and staff. This obviously raises a high barrier for creating a new, from-scratch OS. For instance, Debian provides ca. 37k packages for some five hardware architectures — go figure how much work is put into supporting this stuff. Still, if someone thinks they need to create a new OS for whatever reason, it may be a good idea to use an existing foundation to build on. And this is exactly where OSes based on other OSes come into existence. For instance, Ubuntu builds upon Debian by just importing most packages from it and repackaging only a small subset of them, plus packaging their own, providing their own artwork, default settings, documentation etc. Note that there are variations to this “based on” thing. For instance, Debian fosters the creation of “pure blends” of itself: distributions which use Debian rather directly, and just add a bunch of packages and other stuff only useful for rather small groups of users such as those working in education or medicine or music industry etc. Another twist is that not all these OSes are based on Linux. For instance, Debian also provide FreeBSD and Hurd kernels. They have quite tiny user groups but anyway. Have something to add to the explanation? Sound off in the the comments.

  • maintaining a growing, diverse codebase with continuous integration

    - by Nate
    I am in need of some help with philosophy and design of a continuous integration setup. Our current CI setup uses buildbot. When I started out designing it, I inherited (well, not strictly, as I was involved in its design a year earlier) a bespoke CI builder that was tailored to run the entire build at once, overnight. After a while, we decided that this was insufficient, and started exploring different CI frameworks, eventually choosing buildbot. One of my goals in transitioning to buildbot (besides getting to enjoy all the whiz-bang extras) was to overcome some of the inadequacies of our bespoke nightly builder. Humor me for a moment, and let me explain what I have inherited. The codebase for my company is almost 150 unique c++ Windows applications, each of which has dependencies on one or more of a dozen internal libraries (and many on 3rd party libraries as well). Some of these libraries are interdependent, and have depending applications that (while they have nothing to do with each other) have to be built with the same build of that library. Half of these applications and libraries are considered "legacy" and unportable, and must be built with several distinct configurations of the IBM compiler (for which I have written unique subclasses of Compile), and the other half are built with visual studio. The code for each compiler is stored in two separate Visual SourceSafe repositories (which I am simply handling using a bunch of ShellCommands, as there is no support for VSS). Our original nightly builder simply took down the source for everything, and built stuff in a certain order. There was no way to build only a single application, or pick a revision, or to group things. It would launched virtual machines to build a number of the applications. It wasn't very robust, it wasn't distributable. It wasn't terribly extensible. I wanted to be able to overcame all of these limitations in buildbot. The way I did this originally was to create entries for each of the applications we wanted to build (all 150ish of them), then create triggered schedulers that could build various applications as groups, and then subsume those groups under an overall nightly build scheduler. These could run on dedicated slaves (no more virtual machine chicanery), and if I wanted I could simply add new slaves. Now, if we want to do a full build out of schedule, it's one click, but we can also build just one application should we so desire. There are four weaknesses of this approach, however. One is our source tree's complex web of dependencies. In order to simplify config maintenace, all builders are generated from a large dictionary. The dependencies are retrieved and built in a not-terribly robust fashion (namely, keying off of certain things in my build-target dictionary). The second is that each build has between 15 and 21 build steps, which is hard to browse and look at in the web interface, and since there are around 150 columns, takes forever to load (think from 30 seconds to multiple minutes). Thirdly, we no longer have autodiscovery of build targets (although, as much as one of my coworkers harps on me about this, I don't see what it got us in the first place). Finally, aformentioned coworker likes to constantly bring up the fact that we can no longer perform a full build on our local machine (though I never saw what that got us, either, considering that it took three times as long as the distributed build; I think he is just paranoically phobic of ever breaking the build). Now, moving to new development, we are starting to use g++ and subversion (not porting the old repository, mind you - just for the new stuff). Also, we are starting to do more unit testing ("more" might give the wrong picture... it's more like any), and integration testing (using python). I'm having a hard time figuring out how to fit these into my existing configuration. So, where have I gone wrong philosophically here? How can I best proceed forward (with buildbot - it's the only piece of the puzzle I have license to work on) so that my configuration is actually maintainable? How do I address some of my design's weaknesses? What really works in terms of CI strategies for large, (possibly over-)complex codebases?

  • Master Data Management for Location Data - Oracle Site Hub

    - by david.butler(at)oracle.com
    Most MDM discussions cover key domains such as customer, supplier, product, service, and reference data. It is usually understood that these domains have complex structures and hundreds if not thousands of attributes that need governing. Location, on the other hand, strikes most people as address data. How hard can that be? But for many industries, locations are complex, and site information is critical to efficient operations and relevant analytics. Retail stores and malls, bank branches, construction sites come to mind. But one of the best industries for illustrating the power of a site mastering application is Oil & Gas.   Oracle's Master Data Management solution for location data is the Oracle Site Hub. It is a location mastering solution that enables organizations to centralize site and location specific information from heterogeneous systems, creating a single view of site information that can be leveraged across all functional departments and analytical systems.   Let's take a look at the location entities the Oracle Site Hub can manage for the Oil & Gas industry: organizations, property, land, buildings, roads, oilfield, service center, inventory site, real estate, facilities, refineries, storage tanks, vendor locations, businesses, assets; project site, area, well, basin, pipelines, critical infrastructure, offshore platform, compressor station, gas station, etc. Any site can be classified into multiple hierarchies, like organizational hierarchy, operational hierarchy, geographic hierarchy, divisional hierarchies and so on. Any site can also be associated to multiple clusters, i.e. collections of sites, and these can be used as a foundation for driving reporting, analysis, organize daily work, etc. Hierarchies can also be used to model entities which are structured or non-structured collections of nodes, like for example routes, pipelines and more. The User Defined Attribute Framework provides the needed infrastructure to add single row attributes groups like well base attributes (well IDs, well type, well structure and key characterizing measures, and more) and well geometry, and multi row attribute groups like well applications, permits, production data, activities, operations, logs, treatments, tests, drills, treatments, and KPIs. Site Hub can also model areas, lands, fields, basins, pools, platforms, eco-zones, and stratigraphic layers as specific sites, tracking their base attributes, aliases, descriptions, subcomponents and more. Midstream entities (pipelines, logistic sites, pump stations) and downstream entities (cylinders, tanks, inventories, meters, partner's sites, routes, facilities, gas stations, and competitor sites) can also be easily modeled, together with their specific attributes and relationships. Site Hub can store any type of unstructured data associated to a site. This could be stored directly or on an external content management solution, like Oracle Universal Content Management. Considering a well, for example, Site Hub can store any relevant associated multimedia file such as: CAD drawings of the well profile, structure and/or parts, engineering documents, contracts, applications, permits, logs, pictures, photos, videos and more. For any site entity, Site Hub can associate all the related assets and equipments at the site, as well as all relationships between sites, between a site and multiple parties, and between a site and any purchasable or sellable item, over time. Items can be equipment, instruments, facilities, services, products, production entities, production facilities (pipelines, batteries, compressor stations, gas plants, meters, separators, etc.), support facilities (rigs, roads, transmission or radio towers, airstrips, etc.), supplier products and services, catalogs, and more. Items can just be associated to sites using standard Site Hub features, or they can be fully mastered by implementing Oracle Product Hub. Site locations (addresses or geographical coordinates) are also managed with out-of-the-box address geo-coding capabilities coupled with Google Maps integration to deliver powerful mapping capabilities and spatial data analysis. Locations can be shared between different sites. Centered on the site location, any site can also have associated areas. Site Hub can master any site location specific information, like for example cadastral, ownership, jurisdictional, geological, seismic and more, and any site-centric area specific information, like for example economical, political, risk, weather, logistic, traffic information and more. Now if anyone ever asks you why locations need MDM, think about how all these Oil & Gas entities and attributes would translate into your business locations. To learn more about Oracle's full MDM solution for the digital oil field, here is a link to Roberto Negro's outstanding whitepaper: Oracle Site Master Data Management for mastering wells and other PPDM entities in a digital oilfield context

  • Conference networking for the socially awkward

    - by Melanie Townsend
    Do you approach a room full of strangers with excitement at all the new people you’re going to chat to over coffee and a muffin as you swap tales of how you convinced your manager to give you the day “off”? Or, do you find rooms full of strangers intimidating and begin by scouting out a place you can stand quietly and not be in someone’s way until the next session begins? If you’re on the train to extrovert city, that’s great, well done, move along. If, on the other hand, a room full of strangers who all seem to inexplicably know each other already is more challenge than opportunity, then making those connections with other professionals can be more difficult. So, here’s some advice, some gleaned from other things I’ve read online when trying to overcome my own discomfort in large groups (hopefully minus the infuriating condescension), others are just things I’ve found helpful over the years. Start small Smaller groups are less intimidating, and, now that you’ve taken the plunge to show up, it’s harder to remain inconspicuous. I find it’s easier to speak to new people once the option NOT to has been taken away. You’re there now, smile through the awkward and you’ll be forever grateful when the three people you’ve met and gotten to know here are also at that gigantic conference later on (ideally, introducing you to other people). Smile, or at the very least, stop scowling You probably don’t even know you’re doing it. If your resting face doesn’t come across as manically happy, tinge that with some social anxiety and you become one great ball of unapproachable. Normally, I wouldn’t suggest this as a problem that needs fixing, I have personally honed this face to use while travelling alone all the time. However, if you are indeed hoping to meet some useful people and get the most out of this conference, you may need to remind yourself to smile. Prepare some ice breakers This is going to sound stupid, like “no one does this right?” stupid, but, just, trust me a minute. It’s okay to prepare. You don’t need to write word-for-word questions to ask people and practice them in a mirror – that would be strange. I’m suggesting to just have an arsenal of questions to ask people if you get stuck, what session has been your favorite, which ones are you most looking forward to, have you heard X presenter speak before, what did you think of them? Even just thinking about these things in advance can help, and, as a bonus, while the other person is answering it gives you a moment to tamp down that panic, I mean breathe, I mean get to know them. You’re not alone (in the least creepy way possible) See that person in the corner clutching their phone with a mild deer in the headlights look?  That is potentially your new conference buddy. Starting with something along the lines of: I don’t know about you, the sessions here are great but I find the crowds a little tough to deal with. Mind if I park here for a second? is a decent opener. Just walking around and looking at exhibitors (if applicable) is fine, but it’s a little too easy to wander about and not actually speak to anyone if that’s all you’re doing. If joining a group of people talking is too much to start with, one-on-one can be easier. Have goals Are there people in particular you wanted to speak to? Did you have a personal goal of speaking to at least “x” new people? Are you trying to get a contact in a specific company because you want to work with them on something? Does the business have vague goals as well that you may or may not be judged on later? Making specific goals you can accomplish lets you know whether you’ve actually succeeded in your “networking pursuits” or what you need to work on more for next time. Everyone’s got their own coping technique. Some people are able to remind themselves that “humans are fundamentally social creatures” and somehow that helps them, others drink which is not really something I recommend for professional conferences but to each their own, and some focus on the fact that networking can play a big role in their career path. Just do what works for you, and if there’re any tricks you’ve found helpful over the years, please share em.
