  • Java and .NET cost of use [on hold]

    - by 1110
    I work with .NET technology stack for about 4 years. I am learning and enjoy working with ASP MVC framework and I never did anything serious in other languages. This is not the question like what is better (I read all similar questions). What interest me is the cost of switching. For example: If you are about to start a start-up company today and you are in my situation not too much money, some good idea that you think others will use and have a knowledge of .NET. In my head I have a few questions that I can't answer and I know that somebody with experience can: 1) Java & .NET hosting. Suppose shared hosting is not good enough anymore, your site has grown and you need more resources. How much Java services is cheaper compared to .NET? 2) I didn't follow hype about ORACLE will kill java long time. Does oracle show interest in investing in java. I mean is is safe to bet on java as a technology when starting start-up (basically did oracle show some will to destroy java platform)? 3) I am not sure what I am asking here. When you use Java you can use JEEE stack or Java with third party stack (spring, hibernate, maven etc.). I saw a lot of project that work with second option if web application is not enterprise level but social networking site for example which stack is best pick? Summary of this question is is it safe to jump in to Java learn it and build product based on it. It's not too hard for me to learn it. But how much can I get from it.

  • SOA: Simplifying Cloud, Mobile, and On-premise Integration–Webcast October 24th 2013

    - by JuergenKress
    Proliferation of mobile devices, data explosion, and cloud enablement has caused a dramatic shift in IT. Organizations need to rethink their application infrastructures to accommodate increased processing speeds, heightened security and availability concerns for their applications, all while meeting lowered total cost of ownership. Traditional infrastructures may not be sufficient to accommodate the diversity and complexity of integrations in this new era. Many of today’s IT organizations rely on a Service Oriented Architecture (SOA) backbone to keep their businesses running. SOA adoption and acceptance across industries have led to platform maturity at the application layer level. However, we are at the start of an era where there is a new modus operandi for organizations to thrive and deliver continuously on competitive differentiation. This change is a result of market globalization, explosion in the number of mobile devices, unparalleled growth in voluminous data and innovation that crosses organizational boundaries. Social, mobile, cloud are terms that are revolutionizing the way organizations operate. Oracle SOA Suite is a hot-pluggable software suite to build, deploy and manage Service-Oriented Architectures (SOA).Oracle SOA transforms complex application integration into agile and reusable service-based connectivity by mediating, routing, and managing interactions between services and applications in the enterprise and in the cloud. Oracle SOA Suite's hot-pluggable architecture helps businesses lower upfront costs by allowing maximum re-use of existing IT investments and assets. Join us on this webcast to find out how you can optimize the use of Oracle SOA Suite, simplifying integration, and what does the next generation of SOA has to offer to you. Agenda: What's new in Oracle SOA Simplifying integration Application Integration and SOA Cloud integration with SOA Mobile Integration leveraging Oracle SOA Suite Oracle Delivers on Next Generation SOA Customer Examples Summary and Q&A Webcast Thursday October 24th, 2013 10am CET (8am UTC / 11am EEST)Details at the Registration Page SOA & BPM Partner Community For regular information on Oracle SOA Suite become a member in the SOA & BPM Partner Community for registration please visit www.oracle.com/goto/emea/soa (OPN account required) If you need support with your account please contact the Oracle Partner Business Center.

  • Share files - Ubuntu 12.4 and Windows 7 - one network - password not accepted

    - by gotqn
    I have three machines - two with windows 7 and one with Ubuntu 12.4 version. There are in the same network connected by modem. The two machines shares file with no problem, but they can not see the machine with Ubuntu. On the other hand, I am able to see the share files of the windows machines from the Ubuntu's Network. When I select a folder, it wants the network password - I changed it several times in order to be sure that I am entering the correct one but in every case it says that the password is wrong. I have read some topics about files sharing between Linux and windows in which it is said that I should use samba, but is there a more easy way to do this, using the build it options?

The general theme of the thirty-minute talk was how to improve performance, lower costs, and build the foundation for your cloud service platform using Exadata. Since its introduction in 2008, I’ve watched first-hand as Exadata has evolved from a data warehouse-only system to an OLTP and DW in-memory database machine capable of storing hundreds of terabytes of compressed user data in flash and main memory.  Many of my Exadata customers are now purchasing additional systems as they continue to standardize Oracle 11g deployments on the best database platform available.

  • Ad Service That Lets You Choose Your Ad, and Then Some [on hold]

    - by user3634450
    I'm trying to build an app for both Android and/or iOS where part of the gameplay actually involves ads as a texture. I need to be able to choose which ads I would like to use. I need to be able to be able to identify the ads (which if I can choose which ads show up in the app shouldn't be that hard). I need to be able to swap in and out new ads on what could possibly be a daily basis (and don't want to have to update the app to do it). And as if that wasn't too needy a list, I need to be able to load 50 ads from the pool of ads I deem fit, all to each and every user of the app at least every couple of days. I don't care if the ads pay, I'm not looking for clicks, but I don't want to have to make 50 fake ads every couple of days, from an "artistic" level I don't want the content to feel phony or fake, and I don't really have a way to load content to each user via some internet source (if anyone could name one that would be great). I'm not sure what kind of ad provider would like or even approve of this, in fact just what I've described might be against Google Play's or iTunes' content developer policies, but if anyone could give me any advice to steer me in the right direction it would be greatly appreciated, thank you.

  • Artists and music - i need help to decide wich cms to use.

    - by infty
    A friend has asked me to build a site with the following options: staff members must be able to add new music and artists to the page a gallery must be provided - it is also good if each artist has the ability to have his/her own, smaller, gallery users must be able to vote for artists users must be able to alter in discussions (forums or comments sections) staff members must be able to blog staff members must be able to write articles I did a small project where i actually implementet all of these features, but i want to use an existing content managment system for all of these features so that future devolpers can, hopefully, more easy extend the website. And also, so that i dont have to provide to much documentation. I have never developed a website using an external cms like drupal or wordpress and after seeing hours of tutorial videos of both systems, i still cant make up my mind on wheter i should : a) use Drupal 7 b) use Wordpress 3 c) create my own cms I can only imagine that staff members would also want to create content using iphone or android based mobile devices. But this is not a required feature. Can someone, with experience, please tell me about their experiences with bigger projects like this? The site will approx. have a total of 400 000 - 500 000 visitors (not daily visitors, based on numbers from last year in a period of 4 months)

  • What is the cheapest non-colocation way to serve about 10 static files at a rate of 100 megabits per

    - by Mark Maunder
    I've looked at Amazon S3 and it costs roughly $4746 per month for 100 megabits/s (which translates into 31,640 Gigabytes of data transferred. That's at a rate of $0.15 per gig.) I haven't found a cheaper "cloud" option. I'm curious if there's any other cloud hosting option out there cheaper than S3. Uptime is not an issue because I can build failover for most things into the browser. e.g. I can use javascript to say "if the image didn't load then go to this other URL instead." FYI I'm currently using a colocation facility which is about 30% cheaper than S3 and I'm familiar with colo prices - so this question is really about "cloud" services and by that I mean services where I don't have to worry about the infrastructure.

  • Javascript is not loading

    - by Oden
    Hey, I've got a problem with JavaScript under Ubuntu, that drives me crazy. I'm using Gedit for my web sites since I'm an Ubuntu user. When I start a new website I create (usually with the gnome terminal) folder structure, and I copy the files I need into them. The next step is creating an index.html where I build the design and basic JavaScript functionality. JavaScript is stored in a sub-folder of the project and when i try to load one using the tag in the header, my whole page body disappears. If the source contains a script tag with its own body, and its not the first its code wont run. I've tried to solve the problem by setting chmod to 777 with sudo chmod -R 777 . but nothing changed. CSS is loading correctly, but JS isn't. I'm using the newest version of apache, no mod_rewrite stuff, but i get the same problem when I run the html from file (file:///...) Do anyone know how to solve this problem?

  • VMware9 fails to launch Virtual OS. Ubuntu 12.10 64bit (Unable to change virtual machine power state: Pipe connection has been broken.)

    - by pst007x
    Another issue I need help with. I use VMware for work on Ubuntu 12.04. However for some reasons my VMware Workstation software generates the following error: Unable to change virtual machine power state: Failed to power on '/home/pst007x/vmware/Windows 7 x64/Windows 7 x64.vmx'. Transport (VMDB) error -14: Pipe connection has been broken. Product: VMware® Workstation Version: 9.0.0 build-812388 Host OS Version: 3.5.0-18-generic Ubuntu 12.10 64bit Kernel Linux 3.5.0-18-generic I have seen patches, but nothing works, and the patches are not maintained, broken links. PLEASE NOTE: I know that this has been asked, but there was no answer given that resolves this issue. Unfortunately I have changed all my office and personal PC's to Ubuntu, and use Win7 in a vm, however since 12.10, vm now fails to launch. For me this is a catastrophe, and makes Ubuntu useless for me to use! I am in a desperate situation here, is there is anyone that can offer any help I would be truly appreciative. I have looked on the VMware forums and the only solution is offered for Fedora, but the people posting there are not clear about what the solution is! thanks PLEASE DO NOT CLOSE THIS QUESTION! I have tried everywhere to find a solution, but I have come up blank... Patches referenced to in other posts do not work in this version of VMware...

  • Process video (canon) mov files

    - by user613326
    Well i would like to program something to process HDR made by magic lantern a canon add on. That doesnt change the format its just some kind of add on, that can produce HDR video. Its a bit complex to make such videos so i would like to use some math and make it myself and makee the software freeware (as a thanks to the creators of magic lantern). The problem with that HDR that normal converts have a lot of artifacts, and i would like to make something (for free) using some new algorithms. I have made, this works fine on individual images, my ideas work. I would want to do this on that canon 60d video format. Canons mov format, and am so far out of luck to read that out. It must be possible dough as i know in some projects they do it too. I would not like to export a movie first to jpg and then back to video as that requires a lot of disk space, i would like to retrieve individual frames, do my math based multiple frames, and then build a new movie on it. The output video can be of any type, avi or mov again. Does anyone know of a library who can do that ? (read and save), So i could use it in a C# project (i prefer C# above c++, but c++ is an option to program in to for me).

  • Script to restart BlackBerry services

    - by ICTdesk.net
    Can somebody give me a script advice/example of how to restart services? I have to restart 17 services, but the first 4 services have to be in the right order and after the restart command is given to one of the services, the next one should be started when the previous one is finished. I know I can restart a service by net command, and I can build a delay by for example a ping command that repeats for an x amount of times, but I never know in advance how long it is going to take for a service to restart. Thanks, Kindest regards, Marcel

  • would it be bad to put <span> tags within the <head>, for grouping meta data in schema.org format?

    - by hdavis84
    Alright, I'm currently practicing schema.org microdata, and trying to find the best route for every site I build. I have found that i can piggyback itemprops on open graph meta tags. I would like to piggyback more itemprops on opengraph meta tags. However, schema.org requires you to change itemtypes to define all aspects of a "thing". Say I'm defining a LocalBusiness. Open graph has street address, locality, and region i'd like to piggyback on. I'd have to do something like: <html lang="en" itemscope itemtype="http://schema.org/LocalBusiness"> <head> ... <meta itemprop="name" content="Business Name" /> <meta property="og:url" itemprop="url" content="http://example.com" /> <meta property="og:image" itemprop="image" content="http://example.com/logo.png" /> <span itemprop="address" itemscope itemtype="http://schema.org/PostalAddress"> <meta property="og:street-address" itemprop="streetAddress" content="1234 Amazing Rd." /> <meta property="og:locality" itemprop="addressLocality" content="Greenfield" /> <meta property="og:region" itemprop="addressRegion" content="IN" /> </span> </head> Although there's more that can be added in, this is enough of an example to show what I'm trying to achieve. I've searched the web to see if it is an issue to use spans in the head or not, because I don't want invalid markup. I know I can mark up the address information in the body of the pages, but the route above would be more efficient. Does anyone have an answer for this?

  • Is Samba "remote browse sync" possible across OpenVPN tunnel?

    - by John Reynolds
    I'm connecting 2 TomatoUSB (Shibby build on WNR3500L v2) routers with an OpenVPN routed connection: ----------------------- ----------------------- | Router 1, subnet 20 | <--tunnel--> | Router 2, subnet 21 | ----------------------- ----------------------- Router 1 is the OpenVPN server and Router 2 is a client. Clients attached to the routers on both subnets can ping clients on the other subnet, so the tunnel and routing works. I've enabled file sharing on both, in order to get their Samba WINS servers running. Is it possible to get name resolution across the tunnel? I've tried remote browse sync = 192.168.21.1 in /etc/smb.conf on the server side, to no avail. Also tried using the IP adress that the client gets from the OpenVPN address pool (usually 10.8.0.something), but still no joy.

  • How do you QA and release software quickly with a large team?

    - by sadadasd
    My work used to be a smaller team. We had less than 13 devs for a while. We are now growing rapidly, and are over 20 with plans to be over 30 in a few months. Our process for QA'ing and releasing each build is no longer working. We currently have everyone develop the new code, and stick it onto a staging environment. A few days before our weekly release, we would freeze the staging environment and QA everything. By our normal release time, everything was usually deemed acceptable and pushed out the door to the main site. We reached a point where our code got too big so we could no longer regress the entire site each week in QA. We were ok with that, we just made a list of everything important and only covered that and the new stuff. Now we are reaching a point where all the new stuff each week is becoming too big and too unstable. Our staging environment is really buggy week after week, and we are usually 1-2 hours behind the normal release time. As the team is growing further, we are going to drown with this same process. We are re-evaluating everything, and I personally am looking for suggestions / success stories. Many companies have been where before and progressed beyond, we need to do the same

  • XML Rules Engine and Validation Tutorial with NIEM

    - by drrwebber
    Our new XML Validation Framework tutorial video is now available. See how to easily integrate code-free adaptive XML validation services into your web services using the Java CAMV validation engine. CAMV allows you to build fault tolerant content checking with XPath that optionally use SQL data lookups. This can provide warnings as well as error conditions to tailor your validation layer to exactly meet your business application needs. Also available is developing test suites using Apache ANT scripting of validations.  This allows a community to share sets of conformance checking test and tools . On the technical XML side the video introduces XPath validation rules and illustrates and the concepts of XML content and structure validation. CAM validation templates allow contextual parameter driven dynamic validation services to be implemented compared to using a static and brittle XSD schema approach.The SQL table lookup and code list validation are discussed and examples presented.Features are highlighted along with a demonstration of the interactive generation of actual live XML data from a SQL data store and then validation processing complete with errors and warnings detection.The presentation provides a primer for developing web service XML validation and integration into a SOA approach along with examples and resources. Also alignment with the NIEM IEPD process for interoperable information exchanges is discussed along with NIEM rules services.The CAMV engine is a high performance scalable Java component for rapidly implementing code-free validation services and methods. CAMV is a next generation WYSIWYG approach that builds from older Schematron coding based interpretative runtime tools and provides a simpler declarative metaphor for rules definition.

  • Expanding development team for a startup

    - by acjohnson55
    I'm a software developer and co-founder of a start up that's in a sprint to launch a web app the next 2 months. We have about 3 months of burn time we have before we need to get some funding. By that time, we want to have a product with active users, and ideally some revenue. I'm fairly confident that I can accomplish the task by myself, but I have also never launched a project of this magnitude. The better product we can build in this timespan, the faster we can grow our user base, and the better our fundraising options will be. So I'm looking to bring someone onboard to hack with me. Maybe more than one person. Good help is hard to find, as we all know, and while I'm willing to share equity, I also want that to be contingent on a productive fit. What is the best approach to a trial-type framework for hiring another developer? Something where the other person feels that their work will be rewarded if they do well and that they can't be left empty-handed at my whim, but where I know that if it turns out not to be a good fit, I can pull the cord without significant loss?

  • VMWare Workstation Dev Machine Disks: one fast or four echofriendly raid?

    - by Avi
    I'm building a new dev computer. It will be running a few VMWare Worksation virtual machines - A dev machine running VS-2010, a build machine, a version-control machine, a web server for testing, a "personal" machine running office etc. I'll be connecting the computer to my stereo, so I'll also be running iTunes (possible on a dedicated VM) and I want the computer to be a silent one. I'll probably use an Antec P183 case. I was advised on Serverfault to use Raid10 for performance. Raid 10 uses 4 disks. So, my question is as follows: In terms of heat, noise, reliability, warranty, price, capacity and performance, what would you suggest: A Raid10 4 disk array using eco-friendly disks such as the $94 1TB Western Digital Caviar Green, or one high performance disk such as the 2TB Western Digital Caviar Black at $280?

    Doing a little research on the two to figure out which one may better suit my purposes (communications amongst different hardware). How do they fare against one another? Im far from being a specialist and have no idea where I would even start looking for data to compare and contrast. If possible can someone please answer the following questions in regards to each of these. Can they be networked amongst each other? Can they be easily networked over ethernet? What speeds do they transfer at? (Min, Max, Etc.) Reliability? Best framework to build on top of to support the above? Any standard communications programs? Debugging capability? Any help would be very much appreciated, thanks.

  • Using pkexec policy to run out of /opt/

    - by liberavia
    I still try to make it possible to run my app with root priveleges. Therefore I created two policies to run the application via pkexec (one for /usr/bin and one for /opt/extras... ) and added them to the setup.py: data_files=[('/usr/share/polkit-1/actions', ['data/com.ubuntu.pkexec.armorforge.policy']), ('/usr/share/polkit-1/actions', ['data/com.ubuntu.extras.pkexec.armorforge.policy']), ('/usr/bin/', ['data/armorforge-pkexec'])] ) additionally I added a startscript which uses pkexec for starting the application. It distinguishes between the two places and is used in the Exec-Statement of the desktopfile: #!/bin/sh if [ -f /opt/extras.ubuntu.com/armorforge/bin/armorforge ]; then pkexec "/opt/extras.ubuntu.com/armorforge/bin/armorforge" "$@" else pkexec `which armorforge` "$@" fi If I simply do a quickly package everything will work right. But if I package with extras option: quickly package --extras the Exec-statement will be exchanged. Even if I try to simulate the pkexec call via armorforge-pkexec It will aks for a password and then returns this: andre@andre-desktop:~/Entwicklung/Ubuntu/armorforge$ armorforge-pkexec (armorforge:10108): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Trace/breakpoint trap (core dumped) So ok, I could not trick the opt-thing. How can I make sure, that my Application will run with root priveleges out of opt. I copied the way of using pkexec from synaptic. My application is for communicating with apparmor which currently has no dbus interface. Else I need to write into /etc/apparmor.d-folder. How should I deal with the opt-build which, as far as I understand, is required to submit my application to the ubuntu software center. Thanks for any hints and/or links :-)

  • Cube rotation DX10

    - by German
    Well I'm reading the Frank's Luna DirectX10 book and, while I'm trying to understand the first demo, I found something that's not very clear at least for me. In the updateScene method, when I press A, S, W or D, the angles mTheta and mPhi change, but after that, there are three lines of code that I don't understand exactly what they do: // Convert Spherical to Cartesian coordinates: mPhi measured from +y // and mTheta measured counterclockwise from -z. float x = 5.0f*sinf(mPhi)*sinf(mTheta); float z = -5.0f*sinf(mPhi)*cosf(mTheta); float y = 5.0f*cosf(mPhi); I mean, this explains that they do, it says that it converts the spherical coordinates to cartesian coordinates, but, mathematically, why? why the x value is calculated by the product of the sins of both angles? And the z by the product of the sine and cosine? and why the y just uses the cosine? After that, those values (x, y and z) are used to build the view matrix. The book doesn't explain (mathematically) why those values are calculated like that (and I didn't find anything to help me to understand it at the first Part of the book: "Mathematical prerequisites"), so it would be good if someone could explain me what exactly happen in those code lines or just give me a link that helps me to understand the math part. Thanks in advance!

  • I have discovered a fundamental truth about TV shows and plots

    For years, we have all known (okay, maybe I give people too much credit) that there is a very small finite number of plots.  I propose a project.  Let’s use the blogosphere to catalog those plotlines, and then find and document the episodes of shows that use them, including the show title. As evidence, how many shows have used the following plot line:? The standard “evil twin” plotline?  Once relegated to soaps, it has show up in crime shows, with the twist of DNA.  Step one, concentrate one this one.  Tell me about every show you recall that has used this plot.  I will collect and document the shows on my website (www.loethen.net) and we can build a database of the plots. Step two, what other common themes should I offer up?  How about the bigamist plot line?  The “bad guy was dead” plot line (revenge from the dead"?  The “vast government conspiracy” plotline? Let the games begin….

  • The Increasing Focus on Architecture

    - by Bob Rhubart
    If you follow my updates on Twitter or on the OTN ArchBeat page on Facebook you have probably noticed that I'm a regular reader of Joe McKendrick's SOA blog on ZDNet. Usually I'm content to simply share a link on my social networks when I find one of McKendrick's posts interesting. But with a recent post, In the cloud era, let's start calling IT what it is: 'Innovation Team', McKendrick hit on a point that warrants more than a quick link: "IT is no longer just a department full of people who code, build and maintain systems. IT is the business partner that plans and strategizes what types of technology solutions the business needs to move forward." Of course, what McKendrick is describing is an increased focus on architecture. Assuming that McKendrick's assessment is correct — and I do — that expanding focus, from coding, building, and maintaining systems to planning and strategizing technology solutions that serve the business, isn't limited to the organizational level. The individual roles within the IT organization will also have to shift to a more broadly architectural mindset. McKendrick's post references Dr. Irving Wladawsky-Berger's assessment of cloud computing as a critical "third model" of computing to emerge in the 50-year history of Information Technology. As computing itself evolves, the underlying roles that make computing possible must evolve accordingly. That evolution will be defined by an increased focus on architecture.
