• What Master degree should a programmer have after "ITC"? [closed]

  - by Saleh Feek

  I am sorry if the question is simple. I studied ITC - Information Technology and Computing program, in an Arab university called "Arab Open University". This university actually takes the courses from the Open University in the UK (through a partnership). (Note: some of the courses in the list are different from what I took due to replacement/updating for materials) .......... I am interested in programming in general. It is the same question but in different ways: What is the master degree that is related to a programmer? Generally for someone like me, what is the required/suggested Master degree? For any suggested Master degree please type the formal name for the master degree, so that I can search for it.

• Audiobooks for programmers?

  - by Zoot

  I'm a programmer with a two-hour round trip commute to work each day. I'd like to fill some of that time with audiobooks about software development. Any audiobooks that would help me become a better programmer would be appreciated. I'm thinking that books about design patterns and non-fiction about computing history might be good here, but I'm open to anything. Keeping in mind that I will be listening to this in a car, what are the best audiobooks that I can listen to? EDIT: Many people have also suggested podcasts. This is appreciated, but since podcasts arrive in a constantly arriving stream of data rather than as a finite amount of data, ways to juggle all of these different content streams would also be appreciated. To be more specific to my situation, my commuting vehicle has an MP3 CD player, USB input for MP3 files, and AUX input. I own Android and webOS devices that can be plugged into the AUX input.

• What are unique aspects of a software Lifecycle of an attack/tool on a software vulnerability?

  - by David Kaczynski

  At my local university, there is a small student computing club of about 20 students. The club has several small teams with specific areas of focus, such as mobile development, robotics, game development, and hacking / security. I am introducing some basic agile development concepts to a couple of the teams, such as user stories, estimating complexity of tasks, and continuous integration for version control and automated builds/testing. I am familiar with some basic development life-cycles, such as waterfall, spiral, RUP, agile, etc., but I am wondering if there is such a thing as a software development life-cycle for hacking / breaching security. Surely, hackers are writing computer code, but what is the life-cycle of that code? I don't think that they would be too concerned with maintenance, as once the breach has been found and patched, the code that exploited that breach is useless. I imagine the life-cycle would be something like: Find gap in security Exploit gap in security Procure payload Utilize payload What kind of differences (if any) are there for the development life-cycle of software when the purpose of the product is to breach security?

• Configure Jenkins and Tomcat using Puppet

  - by ex3v

  I'm trying to setup Spring dev environment (jenkins, tomcat) on Vagrant. What I really want to achieve is to limit config to only Puppet scripts, so I can share it with my colleagues and work together on the same environment. So far I managed to set up simple scripts to install jenkins, tomcat and so on, they work fine. What about jenkins configuration though? I'm pretty green in jenkins usage and configuration, not sure if I'm doing it the right way... I found this article and I want to migrate whole setup described in it to Puppet. Any ideas? Thanks.

• Looking software for making an animated cartoon to present a new application/scenario idea

  - by Skarab

  I have an idea for an application (+usage scenario) and I would like to create an animated cartoon that shows a use case for this application and its novelty. My company is a rather big so I am looking for an interesting way to get people know my idea to get feedback/get a green light to further develop it. Therefore I am looking for an application (free or commercial) that I could use to realize such an animated cartoon. I have posted this quesion before on stackoverflow, but I think this might be a better community to ask such a question.

• 2D pathfinding - finding smooth paths

  - by Kooi Nam Ng

  I was trying to implement a simple pathfinding, but the outcome is less satisfactory than what I intended to achieve. The thing is units in games like Starcraft 2 move in all directions whereas units in my case only move in at most 8 directions (Warcraft 1 style) as these 8 directions direct to next available nodes (they move from a tile to next neighboring tile). What should I do in order to achieve the result as in Starcraft 2? Shrink the tile size? On the picture you can see a horizontal line of rock tiles being obstacles, and the found path marked as green tiles. The red line is the path I want to achieve.

• Is software innovation still primarily North American and European? Why, and for how much longer?

  - by limist

  Since this site is read by a global audience of programmers, I want to know if people generally agree that the vast majority of software innovation - languages, OS, tools, methodologies, books, etc. - still originates from the USA, Canada, and the EU. I can think of a few exceptions, e.g. Nginx webserver from Russia and the Ruby language from Japan, but overwhelmingly, the software I use and encounter daily is from North America and the EU. Why? Is history and historical momentum (computing having started in USA and Europe) still driving the industry? And/or, is some nebulous (or real) cultural difference discouraging software innovation abroad? Or are those of us in the West simply ignorant of real software innovation going on in Asia, South America, Eastern Europe, etc.? When, if ever, might the centers of innovation move out of the West? Your experiences and opinions welcome, thanks!

• Benchmarking CPU processing power

  - by Federico Zancan

  Provided that many tools for computers benchmarking are available already, I'd like to write my own, starting with processing power measurement. I'd like to write it in C under Linux, but other language alternatives are welcome. I thought starting from floating point operations per second, but it is just a hint. I also thought it'd be correct to keep track of CPU number of cores, RAM amount and the like, to more consistently associate results with CPU architecture. How would you proceed to the task of measuring CPU computing power? And on top of that: I would worry about a properly minimum workload induced by concurrently running services; is it correct to run benchmarking as a standalone (and possibly avulsed from the OS environment) process?

• Easing the Journey to the Private Cloud with Oracle Consulting

  - by MichaelM-Oracle

  By Sanjai Marimadaiah, Senior Director, Strategy & Business Development – Cloud Solutions, Oracle Consulting Services Business leaders are now leading the charge on how their firms can profit from cloud solutions. Agility and innovation are becoming the primary drivers of the business case for the cloud, even more than the anticipated cost savings. Leaders need to find the right strategy and optimize the use of cloud-based applications across their enterprise-computing infrastructure. The Problem – Current State With prevalent IT practices, many organizations find that they run multiple IT solutions serving similar business needs. This has led to the proliferation of technology stacks, for example: Oracle 10g on Sun T4 running Solaris 9; Oracle 11g on Exadata running Linux; or Oracle 12c on commodity x86 servers. This variance has a huge impact on an organization’s agility and expenses, and requires IT professionals with varied skills as well as on-going training for different systems and tools. Fortunately there is a practical business strategy to overcome this unneeded redundancy. Thus begins a journey to the right cloud computing solution. The Solution – Cloud Services from Oracle Consulting Services (OCS) Oracle Consulting Services (OCS ) works closely with our clients as trusted advisors to proactively respond to business needs and IT concerns. OCS understands that making the transition to cloud solutions begins with a strategic conversation, based on its deep expertise for successfully completing private cloud service engagements with several companies. For a journey to the cloud, Oracle Consulting Services leads the client through four phases– standardization, consolidation, service delivery, and enterprise cloud – to achieve optimal returns. Phase 1 - Standardization Oracle Consulting Services (OCS) works with clients to evaluate their business requirements and propose a set of standard solutions stacks for various IT solutions. This is an opportune time to evaluate cloud ready solutions, such as Oracle 12c, Oracle Exadata, and the Oracle Database Appliance (ODA). The OCS consultants, together with the delivery team, then turn to upgrading and migrating existing solution stacks to standardized offerings. OCS has the expertise and tools to complete this stage in a fraction of the time required by other IT services companies. Clients quickly realize cost savings in tools, processes, and type/number of resources required. This standardization also improves agility of the IT organizations and their abilities to respond to the needs of various business units. Phase 2 - Consolidation During the consolidation phase, OCS consultants programmatically consolidate hundreds of databases into a smaller number of servers to improve utilization, reduce floor space, and optimize maintenance costs. Consolidation helps clients realize huge savings in CapEx investments and shrink OpEx costs. The use of engineered systems, such as Oracle Exadata, greatly reduces the client’s risk of moving to a new solution stack. OCS recommends clients to pursue Phase 1 (Standardization) and Phase 2 (Consolidation) simultaneously to reduce the overall time, effort, and expense of the cloud journey. Phase 3 - Service Delivery Once a client is on a path of standardization and consolidation, OCS consultants create Service Catalogues based on the SLAs requirements and the criticality of the solutions. The number and types of Service Catalogues (Platinum, Gold, Silver, Bronze, etc.) vary from client to client. OCS consultants also implement a variety of value-added cloud solutions, including monitoring, metering, and charge-back solutions. At this stage, clients are able to achieve a high level of understanding in their cloud journey. Their IT organizations are operating efficiently and are more agile in responding to the needs of business units. Phase 4 - Enterprise Cloud In the final phase of the cloud journey, the economics of the IT organizations change. Business units can request services on-demand; applications can be deployed and consumed on a pay-as-you-go model. OCS has the expertise and capabilities to establish processes, programs, and solutions required for IT organizations to transform how they interact with business units. The Promise of Cloud Solutions Depending the size and complexity of their business model, some clients are able to abbreviate some phases of their cloud journey. Cloud solutions are still evolving and there is rapid pace of innovation to transform how IT organizations operate. The lesson is clear. Cloud solutions hold a lot of promise for business agility. Business leaders can now leverage an additional set of capabilities and services. They can ramp up their pace of innovation. With cloud maturity, they can compete more effectively in their respective markets. But there are certainly challenges ahead. A skilled consulting services partner can play a pivotal role as a trusted advisor in the successful adoption of cloud solutions. Oracle Consulting Services has expertise and a portfolio of services to help clients succeed on their journey to the cloud.

• Oracle Fusion Middleware gives you Choice and Portability for Public and Private Cloud

  - by Michelle Kimihira

  Author: Margaret Lee, Senior Director, Product Management, Oracle Fusion Middleware Cloud Computing allows customers to quickly develop and deploy applications in a shared environment.  The environment can span across hardward (IaaS), foundation layer software (PaaS), and end-user software (SaaS). Cloud Computing provides compelling benefits in terms of business agility and IT cost savings.  However, with complex, existing heterogeneous architectures, and concerns for security and manageability, enterprises are challenged to define their Cloud strategy.  For most enterprises, the solution is a hybrid of private and public cloud.  Fusion Middleware supports customers’ Cloud requirements through choice and portability. Fusion Middleware supports a variety of cloud development and deployment models:  Oracle [Public] Cloud; customer private cloud; hybrid of these two, and traditional dedicated, on-premise model Customers can develop applications in any of these models and deployed in another, providing the flexibility and portability they need Oracle Cloud is a public cloud offering.  Within Oracle Cloud, Fusion Middleware provides two key offerings include the Developer cloud service and Java cloud deployment service. Developer Cloud Service Simplify Development: Automated provisioned environment; pre-configured and integrated; web-based administration Deploy Automatically: Fully integrated with Oracle Cloud for Java deployment; workflow ensures build & test Collaborate & Manage: Fits any size team; integrated team source repository; continuous integration; task/defect tracking Integrated with all major IDEs: Oracle JDeveloper; NetBeans; Eclipse Java Cloud Service Java Cloud service provides flexible Java deployment environment for departmental applications and development, staging, QA, training, and demo environments.  It also supports customizations deployments for SaaS-based Fusion Applications customers.  Some key features of Java Cloud Service include: WebLogic Server on Exalogic, secure, highly available infrastructure Database Service & IDE Integration Open, Standard-based Deploy Web Apps, Web Services, REST Services Fully managed and supported by Oracle For more information, please visit Oracle Cloud, Oracle Cloud Java Service and Oracle Cloud Developer Service. If your enterprise prefers a private cloud, for reasons such as security, control, manageability, and complex integration that prevent your applications from being deployed on a public cloud, Fusion Middleware also provide you with the products and tools you need.  Sometimes called Private PaaS, private clouds have their predecessors in shared-services arrangements many large companies have been building in the past decade.  The difference, however, are in the scope of the services, and depth of their capabilities.  In terms of vertical stack depth, private clouds not only provide hardware and software infrastructure to run your applications, they also provide services such as integration and security, that your applications need.  Horizontally, private clouds provide monitoring, management, lifecycle, and charge back capabilities out-of-box that shared-services platforms did not have before. Oracle Fusion Middleware includes the complete stack of hardware and software for you to build private clouds: SOA suite and BPM suite to support systems integration and process flow between applications deployed on your private cloud and the rest of your organization Identity and Access Management suite to provide security, provisioning, and access services for applications deployed on your private cloud WebLogic Server to run your applications Enterprise Manager's Cloud Management pack to monitor, manage, upgrade applications running on your private cloud Exalogic or optimized Oracle-Sun hardware to build out your private cloud The most important key differentiator for Oracle's cloud solutions is portability, between private and public clouds.  This is unique to Oracle because portability requires the vendor to have product depth and breadth in both public cloud services and private cloud product offerings.  Most public cloud vendors cannot provide the infrastructure and tools customers need to build their own private clouds.  In reverse, traditional software tools vendors typically do not have the product and expertise breadth to build out and offer a public cloud.  Oracle can.  It is important for customers that the products and technologies  Oracle uses to build its public is the same set that it sells to customers for them to build private clouds.  Fundamentally, that enables skills reuse,  as well as application portability. For more information on Oracle PaaS offerings, please visit Oracle's product information page.    Resources Follow us on Twitter and Facebook Subscribe to our regular Fusion Middleware Newsletter

• Unidata and RDB migrations to Oracle

  - by llaszews

  Have a couple of unique migrations that don't come along to often. They are Unidata and RDB migrations. The top three things that make these migration more challenging are: 1. No automated data migration tools - Because these migration don't happen that often, there are no tools in the market place to automated the data migration. 2. Application is tied to database - The application needs to be re-architected/re-engineered. Unidata Basic and COBOL for RDB. TSRI can migrate Basic to Java and PL/SQL. Transoft can migrate DEC COBOL to Java. 3. New client hardware potentially involved - Many Unidata and RDB based systems use 'green screens' as the front end. These are character based screens that will run on very old dumb terminals such as: Wyse and DEC 5250 terminals. The user interface can be replicated in a web browser but many times these old terminals do not support web browsers.

• AutoSSH for a robust tunnel

  - by Budric

  I'm trying to start an ssh tunnel from A to B and have it run despite things like: period network/wifi drops on A and remote server reboot on B. My ssh tunnel starts using upstart script on A with event start on (net-device-up IFACE=eth0) I've found autossh which is supposed to handle these kinds of things, but had some trouble getting it to work. The upstart executes: autossh -M 0 -2qTN -o "ServerAliveInterval 30" -o "ServerAliveCountMax 2" -L 5678:somehost:5678 user@B However when I log into B and kill -9 that tunnel session, autossh just exits with "Connection to B closed by remote host." That's not what I expected autossh to do. Any advice on how to set this up? Any GUI service monitoring utilities out there that essentially display a green light if a service is up? Thanks.

• Customizing JBar for Notifications

  - by Ryan Ohs

  Lately I've been using JBar, a very neat jQuery plugin for displaying notifications in my web applications. Unfortunately the original version of JBar only supports binding to the click event of a DOM item. In order to get around this limitation I have modified the source code and posted an updated version on my GitHub account here. The modified version allows you to display a JBar notification by calling a method. I typically use it to display succes or failure messages when doing Ajax calls. I have also included some additional CSS and JS so that you can diplay different styles of notifications. showNotification(message) shows a green "success" message. showWarning(message) shows an orange "warning" message. showMessage(message, className) allows you to specify a custom class to apply to the notification for additional styling purposes. A web page with samples is included.   Get the code here.

• Installed Ubuntu In a low Specs PC and it is too slow, even with LXDE

  - by Herudae

  I'm new with Linux and started with Ubuntu 11.10, I installed it in my PC (Core2Duo 2Ghz, 512Mb Ram DDR2, integrated video in Motherboard), I know the requirements for Unity are 1Gb Ram so I decided to download a Desktop environment more lightweight, so I Installed LXDE, it loads very fast, compared to the 3.5 min from login screen to open desktop in Unity, but it freezes every time I open a single program, I can't even navigate in Internet, it freezes, sometimes for a pair of minutes and the graph at bottom right is all green as if iyt were using 100% CPU, it happens with every program. As additional data it takes 3+ min to get from boot system selection screen to Login screen and 3.5 Min more to get into Ubuntu with Unity, with LXDE it turns to 30 secs aproximately. Is Ubuntu + LXDE Desktop Environment Package = Lubuntu? or should I download Lubuntu directly instead? I installed some other desktop environments, as Gnome but it doesn't log in, the screen just turns grey. Should I get an older Ubuntu version? I'm thinking about uninstalling Ubuntu but I'll try to deplete the options, thanks for your support.

• Triangle Strips and Tangent Space Normal Mapping

  - by Koarl

  Short: Do triangle strips and Tangent Space Normal mapping go together? According to quite a lot of tutorials on bump mapping, it seems common practice to derive tangent space matrices in a vertex program and transform the light direction vector(s) to tangent space and then pass them on to a fragment program. However, if one was using triangle strips or index buffers, it is a given that the vertex buffer contains vertices that sit at border edges and would thus require more than one normal to derive tangent space matrices to interpolate between in fragment programs. Is there any reasonable way to not have duplicate vertices in your buffer and still use tangent space normal mapping? Which one do you think is better: Having normal and tangent encoded in the assets and just optimize the geometry handling to alleviate the cost of duplicate vertices or using triangle strips and computing normals/tangents completely at run time? Thinking about it, the more reasonable answer seems to be the first one, but why might my professor still be fussing about triangle strips when it seems so obvious?
