• VMware or Xen support for AIX on pSeries architecture

  - by A.Rashad

  I tried to find an explicit confirmation on VMware website if there is any chance we could virtualize AIX running on pSeriese architecture (P5, P6 and P7), but in vain. so far we have only one product available which is PowerVM (IBM Product) but we are trying to find alternative solutions to evaluate pros and cons before taking any action. Even Xen mentions the support for Power PC but for Linux not AIX. I hope someone could give an insight on this matter.

• google search engine architecture- how do so many concurrent users do a search on it

  - by stonebold

  With millions of users searching for so many things on google, yahoo and so on. How can the server handle so many concurrent searches? I have no clue as to how they made it so scalable. Any insight into their architecture would be welcomed.

• Duplication of Architecture State means physically extra?

  - by Doopy Doo

  Hyper-Threading Technology makes a single physical processor appear as two logical processors; the physical execution resources are shared and the architecture state is duplicated for the two logical processors. So, this means that there are two sets of basic registers such as Next Instruction Pointer, processor registers like AX, BX, CX etc physically embedded in the micro-processor chip, OR they(arch. state) are made to look two sets by some low level duplication by software/OS.

• More advanced 'Apple Automator' software?

  - by OrangeBox

  Is there any software similar to automator but more advanced? In our situation we have two files with the same name, one is a MOV the other XML. We want to use some of the metadata within the XML to rename both files. Then we want to re-arrange the contents of the XML file so that it is compatible with another piece of software we use (I think this is called mapping) Essentially some software that takes a bunch of variable from existing file and peforms file actions to them. I imagine this would be an easy task using applescript, but im wondering if there is a OSX application similar to Automator that can do the above? Questions are: Is there software that can do the above? Could Automator achieve this? What is the name of this process? If no such software exists, what would be the best kind of script to use? eg. Make an Apple Script, python script etc.

• Third party biometric software.

  - by Iszi

  Most of us with fingerprint readers and such devices probably use the software provided by the vendor, to enable biometric OS login or single sign-on functionality. However, I've recently wondered if there is any third-party software that will do the same thing? This would be similar to how you don't need the manufacturer's software to use a scanner, printer, or webcam - you just use their drivers and your choice of software. Is there anything like this for fingerprint readers or other biometric devices? Free or Open Source projects are preferred, but I'd be interested in learning about any existing solutions regardless. I personally am particularly interested in Windows-compatible software, but I'll leave the query open for any OS.

• Software to replicate one computers display onto many other displays

  - by Joe Taylor

  We have a classroom setup with one teachers pc at the front. I am looking for some software, preferably open source although this is not a deal breaker, to force all displays in the room to replicate the teachers display. Also if this software could be locked so the students could not exit this software while it was running. Does anyone know of any software that could perform this task? I have googled around for a solution but haven't found anything suitable as yet. It would be running on Windows 7 Flavours of the software I have found are: Lanschool and NetOp. Open source alternatives would be better.

• How to prevent people taking software home?

  - by Robert MacLean

  Most companies I have worked at have had either a collection of disks or a network share with the installs of the commonly used software in them. This is to allow the IT dept and skilled users to install the software they need on their work machines very easily. However some users would see this as an opportunity to get "free" software for their home machines. I've seen the draconian approach of locking the machine down completely, but that does not work well (in my view - if you disagree feel free to comment on it) because You add so much extra work to IT Users get that big brother feeling So how do you find a way to prevent users from taking home software but still allowing them to install what they need? You can make the assumption that most of the users in the organisations I work in are smart enough to install software, I'm not worried about the tea lady here.

• Upgrade manually-installed msi by assigning software through gpo

  - by Mr Happy

  In the past I rolled out software by manually installing it on a "golden" workstation, creating an (ghost)image from that and rolling that out to the other workstations. I try not to do that any more for simple/small software, and when possible (if it's an .msi) I assign the software through gpo. I'm having a problem with one of those. The software was manually installed on the image, which was rolled out, and now I have an update for that software (new msi) and I'd like to assign it through gpo. Don't know if it's relevant but it's user assigned. The new version gets installed alongside with the old version (this is possible since the program folder is different between those versions). When I install the same msi by hand, it properly removes/upgrades the old version though. Is what I am trying to do possible?

• Frank Buytendijk on Prahalad, Business Best Practices

  - by Bob Rhubart

    In his video on the questionable value of some business best practices, Frank Buytendijk mentions a recent HBR article by business guru C.K. Prahalad. I just learned that Prahalad passed away this past weekend at the age of 68. (Information Week obit) A couple of years ago I had the good fortune to attend Mr. Prahalad’s keynote address at a Gartner event.  He had an audience of software architects absolutely mesmerized as he discussed technology’s role in the changing nature of business competition.  The often dysfunctional relationship between IT and business has and will probably always be hot-button issue. But during Prahalad’s keynote,  there was a palpable sense that the largely technical audience was having some kind of breakthrough, that they had achieved a new level of understanding about the importance of the relationship between the two camps. Fortunately, Prahalad leaves behind a significant body of work that will remain a valuable resource as business and the technology that supports it continues to evolve.

• Planning development when academic research is involved

  - by Another Anonymous User

  Dear fellow programmers, how do you do "software planning" when academic research is involved? And, on a side note, how do you convince your boss that writing software is not like building a house and it's more like writing a novel? The gory details are below. I am in charge of a small dev team working in a research lab. We started developing a software with the purpose of going public one day (i.e. sell and make money off that). Such software depends on, amongst other things, at least two independent research lines: that is, there are at least two Ph.D. candidates that will, hopefully, one day come out with a working implementation of what we need. The main software depends also on other, more concrete resources that we as developers can take care of: graphics rendering, soft bodies deformation, etc. My boss asked me to write the specifications, requirements AND a bloody GANTT chart of the entire project. Faced with the fact that I don't have a clue about the research part, and that such research is fundamental for the software, he said "make assumptions." For the clarity of the argument, he is a professor whose Ph.D. students should come up with the research we need. And he comes from a strictly engineering background: plan everything first, write down specifications and only then write down code that "it's the last part". What I am doing now: I broke down the product in features; each 'feature' is, de facto, a separate product; Each feature is built on top of the previous one; Once a feature (A) has a working prototype the team can start working on the next feature (B), while QA for is being done for A (if money allows, more people can be brought in, etc.); Features that depend on research will come last: by then, hopefully, the research part will be completed (when is still a big question) ; Also, I set the team to use SCRUM for the development of 'version 1.0', due in a few months. This deadline could be set based on reasonable assumptions: we listed all required features, we counted our availability, and we gave a reasonable estimate. So my questions, again, are: How do I make my boss happy while at the same time get something out the door? How do I write specifications for something we -the developers- have no clue whether it's possible to do or not? (We still haven't decided which libraries to use for some tasks; we'll do so when we'll need to) How do I get the requirements for that, given that there are yet no clients nor investors, just lots of interests and promises? How do I get peace in the world? I am sure at least one of my questions will be answered :) ps: I am writing this anonymously since a potential investor might backfire if this is discovered. Hope you'll understand. However I must say I do not like this mentality of 'hiding the truth': this program will likely benefit many, and not being able to talk openly about this (with my name and my reputation attached) feels like censorship. But alas, I care more about your suggestions now.

• Architectural and Design Challenges with SOA

  With all of the hype about service oriented architecture (SOA) primarily through the use of web services, not much has been said about potential issues of using SOA in the design of an application. I am personally a fan of SOA, but it is not the solution for every application. Proper evaluation should be done on all requirements and use cases prior to deciding to go down the SOA road. It is important to consider how your application/service will handle the following perils as it executes. Example Challenges of SOA Network Connectivity Issues Handling Connectivity Issues Longer Processing/Transaction Times How many of us have had issues visiting our favorite web sites from time to time? The same issue will occur when using service based architecture especially if it is implemented using web services. Forcing applications to access services via a network connection introduces a lot of new failure points to the application. Potential failure points include: DNS issues, network hardware issues, remote server issues, and the lack of physical network connections. When network connectivity issues do occur, how are the service clients are implemented is very important. Should the client wait and poll the service until it is accessible again? If so what is the maximum wait time or number of attempts it should retry. Due to the fact of services being distributed across a network automatically increase the responsiveness of client applications due to the fact that processing time must now also include time to send and receive messages from called services. This could add nanoseconds to minutes per each request based on network load and server usage of the service provider. If speed highly desirable quality attribute then I would consider creating components that are hosted where the client application is located. References: Rader, Dave. (2002).

• How do you properly organize a commercial game?

  - by Reactorcore

  For the past months I've been studying programming and I've finally learned how to code, but one thing that is confusing me is how to properly organize the design of a game project - code wise. The game I'm building is a pretty standard commercial game. It has the basic components of a normal game: A world, characters and items interacting with each other and all of this is run by game manager. Basically you play as a hero in a world and do stuff. Fight, explore and interact. Think of your standard adventure game that starts off with an intro, goes to the menu system, then gets into the game and back to the menu. Pretty much like 99% of any commercial game or otherwise serious game projects. Thats what I'm aiming at. The problem is: How do you properly code a commercial game architecture? How do you organize it? How do you make it not become unmaintainable spaghetti code? What specific things to keep in mind when building this, codewise? How you can help me: a) Please tell how do you code your own game projects. What is your thought-process when designing the architecture? b) Recommend books, blogs, tutorials, videos or anything else on how to organize a commercial video game. c) Give hints and tips on do's/don'ts when building a game, codewise. Please help!

• SOA Starting Point: Methods for Service Identification and Definition

  As more and more companies start to incorporate a Service Oriented Architectural design approach into their existing enterprise systems, it creates the need for a standardized integration technology. One common technology used by companies is an Enterprise Service Bus (ESB). An ESB, as defined by Progress Software, connects and mediates all communications and interactions between services. In essence an ESB is a form of middleware that allows services to communicate with one another regardless of framework, environment, or location. With the emergence of ESB, a new emphasis is now being placed on approaches that can be used to determine what Web services should be built. In addition, what order should these services be built? In May 2011, SOA Magazine published an article that identified 10 common methods for identifying and defining services. SOA’s Ten Common Methods for Service Identification and Definition: Business Process Decomposition Business Functions Business Entity Objects Ownership and Responsibility Goal-Driven Component-Based Existing Supply (Bottom-Up) Front-Office Application Usage Analysis Infrastructure Non-Functional Requirements  Each of these methods provides various pros and cons in regards to their use within the design process. I personally feel that during a design process, multiple methodologies should be used in order to accurately define a design for a system or enterprise system. Personally, I like to create a custom cocktail derived from combining these methodologies in order to ensure that my design fits with the project’s and business’s needs while still following development standards and guidelines. Of these ten methods, I am particularly fond of Business Process Decomposition, Business Functions, Goal-Driven, Component-Based, and routinely use them in my designs.  Works Cited Hubbers, J.-W., Ligthart, A., & Terlouw , L.

• Repacked proprietary software keeps updating the same deb

  - by Johannes

  I repacked a proprietary program delivered as tar file to a deb file for having a company wide repository. I used reprepro to set up a repository and signed it. A unix timestamp is faking a versioning numbering, so I can have different (real) versions installed at the same time. Almost everything works as expected. The deb file looks like this: mysoft8.0v6_1366455181_amd64.deb Only problem on a client machine it tries to install the same deb file over and over again because it thinks its an update. What do I miss: control file in deb package looks like this: Package: mysoft8.0v6 Version: 1366455181 Section: base Priority: optional Architecture: amd64 Installed-Size: 1272572 Depends: Maintainer: me Description: mysoft 8.0v6 dpkg repackaging and the config in the repository: /mirror/mycompany.inc/conf/distributions: Origin: apt.mycompany.inc Label: apt repository Codename: precise Architectures: amd64 i386 Components: main Description: Mycompany debian/ubuntu package repo SignWith: yes Pull: precise Help much appreciated Added guide: This Is the guide I used to create the repository.

• Where can I find a good software implementation plan template?

  - by Corpsekicker

  This is not "programming" related as much as it is "software engineering" related. I am required to produce an implementation for additional functionality to a complete system. All I am armed with is knowledge of the existing architecture and a functional spec with visual requirements, user stories and use cases. Is there a standardised way to go about this? I suck at documentation.

• Any screen capture software that captures webcam, microphone inputs too ?

  - by mohanr

  I am going to conduct a user study. Apart from capturing the screen while the user is interacting with the system, I also want to capture the video/audio of the user. Is there any software that in addition to capturing the screen also overlays it with the webcam/microphone inputs. The goal is to capture the complete experience of the user: key/mouse interactions with the system along with their facial/vocal responses. I know that I can maybe run a screen-capture software and also run a software for capturing webcam audio/video alongside and try to sync/overlay both these streams with timestamps. But I am going to be dealing with probably several hundred hours of data. So I am looking for a tool that can streamline the process for me amap and help me keep my sanity at end of the process. Thanks,

• Where to Store the Protection Trial Info for Software Protection Purpose

  - by Peter Lee

  It might be duplicate with other questions, but I swear that I googled a lot and search at StackOverflow.com a lot, and I cannot find the answer to my question: In a C#.Net application, where to store the protection trial info, such as Expiration Date, Number of Used Times? I understand that, all kinds of Software Protection strategies can be cracked by a sophiscated hacker (because they can almost always get around the expiration checking step). But what I'm now going to do is just to protect it in a reasonable manner that a "common"/"advanced" user cannot screw it up. OK, in order to proof that I have googled and searched a lot at StackOverflow.com, I'm listing all the possible strategies I got: 1. Registry Entry First, some users might not have the access to even read the Registry table. Second, if we put the Protection Trial Info in a Registry Entry, the user can always find it out where it is by comparing the differences before and after the software installation. They can just simply change it. OK, you might say that we should encrypt the Protection Trial Info, yes we can do that. But what if the user just change their system date before installing? OK, you might say that we should also put a last-used date, if something is wrong, the last-used date could work as a protection guide. But what if the user just uninstall the software and delete all Registry Entries related to this software, and then reinstall the software? I have no idea on how to deal with this. Please help. A Plain File First, there are some places to put the plain file: 2.a) a simple XML file under software installation path 2.b) configuration file Again, the user can just uninstall the software and remove these plain file(s), and reinstall the software. - The Software Itself If we put the protection trial info (Expiration Date, we cannot put Number of Used Times) in the software itself, it is still susceptible to the cases I mentioned above. Furthermore, it's not even cool to do so. - A Trial Product-Key It works like a licensing process, that is, we put the Trial info into an RSA-signed string. However, it requires too many steps for a user to have a try of using the software (they might lose patience): 4.a) The user downloads the software; 4.b) The user sends an email to request a Trial Product-Key by providing user name (or email) or hardware info; 4.c) The server receives the request, RSA-signs it and send back to the user; 4.d) The user can now use it under the condition of (Expiration Date & Number of Used Times). Now, the server has a record of the user's username or hardware info, so the user will be rejected to request a second trial. Is it legal to collection hardware info? In a word, the user has to do one more extra step (request a Trial Product Key) just for having a try of using the software, which is not cool (thinking myself as a user). NOTE: This question is not about the Licensing, instead, it's about where to store the TRIAL info. After the trial expires, the user should ask for a license (CD-Key/Product-Key). I'm going to use RSA signature (bound to User Hardware)

• gcc architecture question

  - by Andy

  Hi, I'm compiling my program with architecture set to -mtune=i386 However, I'm also linking statically against several libs (libpng, zlib, jpeglib, vorbisfile, libogg). I've built these libs on my own using configure and make, so I guess these libs were built with architecture being set to my system's architecture which would be i686. But I don't want that! I want my program to run on i386, too, so I need to make sure that all these libs that I'm statically linking against are built for i386, too. So my question: Is there a convenient way to build libpng/zlib/jpeglib/vorbisfile/libogg etc. for i386 or do I have to modify all of their makefiles manually and make sure that -mtune is set to i386? Thanks for help! Andy

• Flex Framework vs. Micro-Architecture

  - by droboZ

  I'm in the process of choosing a framework for my flex development, and one of the questions that was asked about a framework was "is this a framework or a micro-architecture"? Can someone clarify what's the difference? What exactly is a framework, and when can we start calling what we have a framework? I work with FlexBuilder3 (now called FlashBuilder4) and have a lot of standard things that I do for almost all projects, and components that I created for easy re-use. Some are very very small, but the benefit of a 1-liner has been immense for me instead of repeating the code over and over. So in the framework/micro-architecture scheme, can I say that these are my internal in-house framework or are they part of a micro-architecture? Trying to understand this topic better.

• What issues carry the highest risk in a software project?

  - by Mehrdad Afshari

  Clearly, software projects are different from other industries in terms of many things like for instance, quality assurance, project progress measurement, and many other things. Unique characteristics of software projects also makes the risk management process unique. Lots of issues in a project might lead it to unacceptable delay or failure to deliver business value. They might even make a complete disaster in the project. What are the deadliest risk factors in a software project? How to analyze, prevent and handle them? Particularly, I'm interested in the issues that you can detect from the beginning and you should keep an eye on (for example, you might be told about a third-party API that the current application uses and lacks documentation). Please share your experiences if they are relevant.

• What area of Software Engineering are you going to focus your research on?

  - by ultrajohn

  hi guys! I have this very subjective question regarding software engineering. Let's say you want to pursue a graduate degree i.e. master degree with a major in software engineering, what particular topic or area of research in the field are your going to pursue? From your experience, what are the different aspects of software engineering which are vital in our field that are "under"(less) research. I know this is very subjective, I just want to elicit ideas from you guys whom I think knows a lot about the field. Thanks a lot.
