  • Website hosted at home pingable from outside, but not browseable from outside

    - by Richard DesLonde
    I have a simple setup. Server at home has local I.P. 192.168.1.3 IIS is running on the server and the website is up. Windows firewall on the server has an exception rule for port 80 TCP Router has static I.P. XX.XXX.XX.XXX Router is forwarding TCP port 80 to 192.168.1.3 My domain registrar is my DNS host and is pointing to the static I.P. XX.XXX.XX.XXX of the router Here's what I can and can't do. I can browse the website from within my home network either by I.P. or domain name. I can ping the domain and the I.P. from outside the network (from a computer at work). I can't browse the website either by domain name or by I.P. Wierd. Why I can't browse my website? Incidentally, I wasn't sure this question was appropriate for SO, but after finding a few others similar to it on SO, and no comments on those questions saying anything about it being innapropriate, I decided I would post this question. Let me know if this is not appropriate for SO, or is more appropriate for another of the SE websites. Thanks!

  • WebCenter Customer Advisory Board meetings kick off Oracle Open World 2012!

    - by Lance711
    Welcome to OpenWorld! OpenWorld 2012 got underway today with a series of meetings with the members of the WebCenter Customer Advisory Board. Led by the WebCenter Product Management team, these meetings are a great way for the product team and customers to directly interact and discuss real-life business challenges, product details and to discuss upcoming features and functionality. This year, board members participated in discussions around live demos around product enhancements that will be featured throughout the coming week. Highlights included a variety of new mobile and social solutions, a great new user interface for WebCenter Content plus new Portal and Sites functionality that makes the experience for the everyday user a lot more pleasant. The day kicked off with Roel Stalman, VP of Product Management, giving a detailed overview of what’s new in WebCenter. Given all the improvements to discuss, this session went over 2 hours! Roel showcased the brand new UI for Content, Portal and Sites. He also gave live demos of the new mobile apps for WebCenter Content, Portal and the Oracle Social Network.  The attendees then broke into sub-groups in order to deep-dive with Product Management for the Portal, Sites, and Content product areas on specific functionality and application integrations. If you are here in San Francisco this week for OpenWorld, I definitely recommend stopping by the WebCenter area in the Moscone West Exhibition Hall to see some of this new functionality for yourself. And be sure to check out the WebCenter sessions throughout the week as those give us a chance to discuss direction and strategy, answer your questions and get your feedback and ideas. For those of you could not make it to OpenWorld this year, we miss you! You can stay in touch with what is happening via this blog and by following #oow and #webcenter on Twitter. Additionally, we will be rolling out details on upcoming products and release info over the coming months via this blog and web seminars. Stay tuned!

    - by Slay
    I have some questions about instances and load balancing in amazon s3. I can configured an instances in s3, but i do not understand how to deal with many instances in s3. Currently, my instance is loaded with mysql, php etc (ALL IN ONE). However how do i ensure my instances is scaling? E.g if i have a site that is suppose to be handled using 3 instances and using amazon rds. Do i need to host my code base in the 3 instances? how do people normally do this? like facebook has 1000+ servers. Do they host their code base in all the 1000+ servers? Thanks

  • NTFS disk mounted as fuseblk in ubuntu 12.10 is very slow and a lot of errors when rsync. Is that not a rare thing?

    - by Pablo Marin-Garcia
    I am having problems with a NTFS disk mounted as a fuseblk in my ubuntu 12.10 through external usb3. When I did a 1.1TB backup with rsync the speed was 1-2MB/s (wiht a ext4 disk speed was 70 MB/s before and after trying the NTFS disk). Also after one hour errors started to appear: rsync: write failed on "xxx": No such file or directory recv_files: "yyy" is a directory #but this file is a FILE not a dir ??!! .... As this is the first time I have mounted the NTFS in linux for heavy usage (the data would be used in windows afterwards), I would like to know if this kind of thinks are common o was only that something became unstable in my system and a simply restart would probably have solved it. This leads me to the these questions: Can I trust fuse for manage NTFS disks? Or is a problem of the NTFS tools in linux not yet totally stables for writing? Do people is still suffering from low performance with fuse-NTFS vs ext4 (in the past I have read about people complaining about this)?

  • Is my current employer expecting too much?

    - by priyank patel
    This is my first job as a programmer.I am working on ASP.NET/C#,HTML,CSS,Javascript/Jquery. I am working for a firm which develops software for small banking firms. Currently they have their software running in 100 firms.Their software is developed in Visual Fox Pro. I was hired to develop online version of this software.I am the solo developer. My boss is another developer.So my company has two developers. My boss doesnot have any idea about .NET development.I am working on their project since 8 months.The progress is surely there but not very big. I try my best to do what my boss asks.But the project just seems too ambitious for me. The company doesnot have any planning for the project.They just ask me to develop what their older software provides.So I have to deal with front end , back end,review codes , design architecture and etc. I have decided to give my best.I try a lot.But the project sometimes just seems to be overwhelming. So my questions is , is it normal for a programmer to be in this place. I always feel the need to work in atleast a small team if not big one. Are my employers just expecting too much of a fresher.Or is that I being a programmer am lacking the skills to deal with this. I am just not able judge my condition.Also I am paid very low salary.I do work on saturday as well. Can anyone just help me judge this scenario? Any suggestions are welcome.

  • Getting Started with StreamInsight 2.1

    - by Roman Schindlauer
    If you're just beginning to get familiar with StreamInsight, you may be looking for a way to get started. What are the basics? How can I get my first StreamInsight application running so I can see how it works? Where is the 'front door' that will get me going? If that describes you, then this blog entry might be just what you need. If you're already a StreamInsight wiz, keep reading anyway - you may find some helpful links here that you weren't aware of. But here's what we'd like from you experienced readers in particular: if you know of other good resources that we missed, please feel free to add them in the comments below. We appreciate you sharing your expertise. The Book The basic documentation for StreamInsight is located in the MSDN Library (Microsoft StreamInsight 2.1). You'll notice that previous versions of StreamInsight are still there (1.2 and 2.0), but if you're just getting started you can stick to the 2.1 section. The documentation has been organized to function as reference material, which is fine after you're familiar with the technology. But if you're trying to learn the basics, you might want to take a different path instead of just starting at the top. The following is one map you can use. What Is StreamInsight? Here is a sequence of topics that should give you a good overview of what StreamInsight is and how it works: Overview answers the question, "what is it?" StreamInsight Server Architecture gives you a quick look at a high-level architectural drawing StreamInsight Concepts lays out an overview of the basic components Deploying StreamInsight Entities to a StreamInsight Server describes the mechanics of how these components work together Getting an Example Running Once you have this background, go ahead and install StreamInsight and get a basic example up and running: Installation download and install the software StreamInsight Examples walk through a set of 3 simple StreamInsight applications that work together to demonstrate what you learned in the topics above; you can copy and paste the code into Visual Studio, compile, and run That's it - you now have a real, functioning StreamInsight system! Now that you have a handle on the basics, you might want to start digging deeper. Digging Deeper Here's a suggested path through the documentation to help you understand the next layer of StreamInsight technologies: Using Event Sources and Event Sinks sources supply data and sinks consume it; this topic gives you an overview of how they work Publishing and Connecting to the StreamInsight Server practical details on how to set up a StreamInsight server A Hitchhiker’s Guide to StreamInsight 2.1 Queries queries are the heart of how StreamInsight performs data analytics, and this whitepaper will help you really understand how they work Using StreamInsight LINQ root through this section for technical details on specific query components Using the StreamInsight Event Flow Debugger in addition to troubleshooting, the debugger is a great way to learn more about what goes on inside a StreamInsight application And Even Deeper Finally, to get a handle on some of the more complex things you can do with StreamInsight, dig into these: Input and Output Adapters adapters can be useful for handling more complex sources and sinks Building Resilient StreamInsight Applications a resilient application is able to recover from system failures Operations this section will help you monitor and troubleshoot a running StreamInsight system The StreamInsight Community As you're designing and developing your StreamInsight solutions, you probably will find it helpful to see working examples or to learn tips and tricks from others. Or maybe you need a place to post a vexing question. Here are some community resources that we have found useful. If you know of others, please add them in the comments below. Code samples and tools Official StreamInsight code samples Introduction to LinqPad Driver for StreamInsight 2.1 - LinqPad is a very useful tool for developing queries The following case studies are based on earlier versions of StreamInsight, but they still are useful examples: Microsoft Media Analytics - real-time monitoring and analytic Edgenet - responding to information from multiple source ICONICS - managing energy usage Blogs Microsoft StreamInsight Ruminations of J.net Richard Seroter's Architecture Musings pluralsight Forums MSDN StreamInsight Forum stackoverflow Training Microsoft StreamInsight Fundamentals (“Introducing StreamInsight” is free) from pluralsight Twitter @streaminsight   You’re a StreamInsight Expert That should get you going.

  • Determining who is running with administrator rights?

    - by Alex C.
    I work at a small non-profit organization with about 55 desktop PCs running Windows XP Pro. The domain controller is running Windows Server 2003. I have a two-part question (note that I'm a bit of a newb when it comes to network administration). Part 1: Is there some simple way that I can determine which accounts are logged in with administrator rights? Part 2: Is there a way that I can remove administrator rights from users without sitting down at each individual machine? Thanks for considering my questions.

  • DNS server at router level vs. computer level

    - by Craig
    I've three questions. Is it better/faster/optimal to set up your server's preferred and alternate DNS servers in your OS's network settings or in your router settings? Will it cause problems if it is set up in both places, both pointing to the same IPs? I am running Windows and I have my network assign a static IP to one of my computers. This doesn't allow me to obtain the DNS server addresses from my router automatically. Is there an IP I can put in that will cause it to take the DNS server addresses from the router?

  • IIS 7.x Application Pool Best Practices

    - by Eric
    We are about to deploy a bunch of sites to some new servers. I have the following questions about application pools: 1) It seems advisable to have an application pool per website. Are there any caveats to this approach? Can one application pool, for example, hog all the CPU, Memory, Etc...? 2) When should you allow multiple worker processes in an application pool. When should you not? 3) Can private memory limit be used to prevent one application pool from interfering with another? Will setting it too low cause valid requests to recycle the application pool without getting a valid response? 4) What is the difference between private and virtual memory limits? 5) Are there compelling reasons NOT to run one application pool per site? Thanks!

  • Should you disable page file with SSD?

    - by Pyrolistical
    I've been reading http://serverfault.com/questions/23621/any-benefit-or-detriment-from-removing-a-pagefile-on-an-8gb-ram-machine, and it has a lot of great information. But assuming you have more than enough ram, I think page file should be disabled on SSD to extend the life time. I know you would lose the core dump on crash, but not many people need that information. From my understand without a page file as you reach the limit of your ram that might trigger thrashing on disk. But for SSDs there is no concept of thrashing, reads are fast. What do you guys think?

  • Constructor vs setter validations

    - by Jimmy
    I have the following class : public class Project { private int id; private String name; public Project(int id, String name, Date creationDate, int fps, List<String> frames) { if(name == null ){ throw new NullPointerException("Name can't be null"); } if(id == 0 ){ throw new IllegalArgumentException("id can't be zero"); } this.name = name; this.id = id; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } } I have three questions: Do I use the class setters instead of setting the fields directly. One of the reason that I set it directly, is that in the code the setters are not final and they could be overridden. If the right way is to set it directly and I want to make sure that the name filed is not null always. Should I provide two checks, one in the constructor and one in the setter. I read in effective java that I should use NullPointerException for null parameters. Should I use IllegalArgumentException for other checks, like id in the example.

  • Working with data and meta data that are separated on different servers

    - by afuzzyllama
    While developing a product, I've come across a situation where my group wants to store meta data for data entry forms (questions, layout, etc) in a different database then the database where the collected data is stored. This is mostly for security because we want to be able to have our meta data public facing, while keeping collected data as secure as possible. I was thinking about writing a web service that provides the meta information that the data collection program could access. The only issue I see with this approach is the front end is going to have to match the meta data with the collected data, which would be more efficient as a join on the back end. Currently, this system is slated to run on .NET and MSSQL. I haven't played around with .NET libraries running in SQL, but I'm considering trying to create logic that would pull from the web service, convert the meta data into a table that SQL can join on, and return the combined data and meta data that way. Is this solution the wrong way to approach the problem? Is there a pattern or "industry standard" way of bringing together two datasets that don't live in the same database?

  • Norton Ghost usage, Linux? ISO? Server? MBR?

    - by overtherainbow
    Before evaluating Symantec/Norton Ghost to image partitions, I have a couple of questions about using this tool: In the product page, it only mentions Windows: Can Norton image Linux partitions as well? Can I burn an ISO to create/recover images? The ISO's I found seem only able to restore an image but not create one. Does it mean that images can only be created from within a running Windows? For Windows partitions: Does it support both regular and Server versions? Acronis doesn't image Server partitions in the regular version When restoring an image, does Norton give the option of including/excluding the MBR? Thank you.

  • Correct level of abstraction for a 3d rendering component?

    - by JohnB
    I've seen lots of questions around this area but not this exact question so apologies if this is a duplicate. I'm making a small 3d game. Well to be honest, it's just a little hobby project and likely won't turn out to be an actual game, I'll be happy to make a nice graphics demo and learn about 3d rendering and c++ design. My intent is to use direct3d9 for rendering as I have some little experience of it, and it seems to meet my requirements. However if I've learned one thing as a programmer it's to ask "is there any conceivable reason that this component might be replaced by a different implmentation" and if the answer is yes then I need to design a proper abstraction and interface to that component. So even though I intend to implment d3d9 I need to design a 3d interface that could be implemented for d3d11, opengl... My question then is what level is it best to do this at? I'm thinking that an interface capable of creating and later drawing Vertex buffers and index buffers Textures Vertex and Pixel "shaders" Some representation of drawing state (blending modes etc...) In other words a fairly low level interface where my code to draw for example an animated model would use the interface to obtain abstract vertex buffers etc. I worry though that it's too low level to abstract out all the functionallity I need efficiently. The alternative is to do this at a higher level where the interface can draw objects, animations, landscapes etc, and implement them for each system. This seems like more work, but it more flexible I guess. So that's my question really, when abstracting out the drawing system, what level of interface works best?

  • Big Data – How to become a Data Scientist and Learn Data Science? – Day 19 of 21

    - by Pinal Dave
    In yesterday’s blog post we learned the importance of the analytics in Big Data Story. In this article we will understand how to become a Data Scientist for Big Data Story. Data Scientist is a new buzz word, everyone seems to be wanting to become Data Scientist. Let us go over a few key topics related to Data Scientist in this blog post. First of all we will understand what is a Data Scientist. In the new world of Big Data, I see pretty much everyone wants to become Data Scientist and there are lots of people I have already met who claims that they are Data Scientist. When I ask what is their role, I have got a wide variety of answers. What is Data Scientist? Data scientists are the experts who understand various aspects of the business and know how to strategies data to achieve the business goals. They should have a solid foundation of various data algorithms, modeling and statistics methodology. What do Data Scientists do? Data scientists understand the data very well. They just go beyond the regular data algorithms and builds interesting trends from available data. They innovate and resurrect the entire new meaning from the existing data. They are artists in disguise of computer analyst. They look at the data traditionally as well as explore various new ways to look at the data. Data Scientists do not wait to build their solutions from existing data. They think creatively, they think before the data has entered into the system. Data Scientists are visionary experts who understands the business needs and plan ahead of the time, this tremendously help to build solutions at rapid speed. Besides being data expert, the major quality of Data Scientists is “curiosity”. They always wonder about what more they can get from their existing data and how to get maximum out of future incoming data. Data Scientists do wonders with the data, which goes beyond the job descriptions of Data Analysist or Business Analysist. Skills Required for Data Scientists Here are few of the skills a Data Scientist must have. Expert level skills with statistical tools like SAS, Excel, R etc. Understanding Mathematical Models Hands-on with Visualization Tools like Tableau, PowerPivots, D3. j’s etc. Analytical skills to understand business needs Communication skills On the technology front any Data Scientists should know underlying technologies like (Hadoop, Cloudera) as well as their entire ecosystem (programming language, analysis and visualization tools etc.) . Remember that for becoming a successful Data Scientist one require have par excellent skills, just having a degree in a relevant education field will not suffice. Final Note Data Scientists is indeed very exciting job profile. As per research there are not enough Data Scientists in the world to handle the current data explosion. In near future Data is going to expand exponentially, and the need of the Data Scientists will increase along with it. It is indeed the job one should focus if you like data and science of statistics. Courtesy: emc Tomorrow In tomorrow’s blog post we will discuss about various Big Data Learning resources.

    BACKGROUND My team gave a demo to a large audience - we recorded the audio of the demo in multiple locations in the room (3) the audio was recorded using cheap laptop microphones I was not involved in the recording of the audio or the demo Both audio files suck in some form the first one is of a recording near the speaker - which clearly gets his voice but the the audience is audience is muffled - also this one is slightly noisy The second recording was done in the middle of the audience - it gets the audience questions clearly but actually gets the speaker rather sometimes well and sometimes poorly (not all the speakers spoke loudly enough to be heard) MY QUESTION Is there any techinque or software which can be used to merge these audio files in such a way that the best qualities of each are preserved. I am NOT asking now to simply merge them together in one track - I've already done that in Audacity and it is certainly better - what I am looking for could be considered closer to how HDR images are created - multiple exposures combined into an enhanced new version which is not simply an average of the inputs. NOTE Am not an "Audio" guy - just a normal user

In the next step i got this error. http://web1.toshiba.ca/support//techsupport/tsbs/all/-tsb001404.htm So, what should i do to retain my files in d drive and only allow the installation to delete c drive?

  • Good Free Backup Tool - with provisos

    - by vaccano
    I have seen some Backup Questions around. But they are not quite what I am looking for. I would like to have a back up of my entire hard drive (to an external drive). I would like it to be the kind that has a base backup then just backs up the changes since the last backup. I would like it to be able to have a fully restorable image of my hard drive (not just key files). Lastly I would like it to be free (or super cheap). (The above requirements are important, but I will have to drop them if they up the price as my boss will not pay for them.) I have a Solid State Hard Drive 250 GB backing up to a 1TB external hard drive using Windows XP.

  • New Management Console in Java SE Advanced 8u20

    - by Erik Costlow-Oracle
    Java SE 8 update 20 is a new feature release designed to provide desktop administrators with better control of their managed systems. The release notes for 8u20 are available from the public JDK release notes page. This release is not a Critical Patch Update (CPU). I would like to call attention to two noteworthy features of Oracle Java SE Advanced, the commercially supported version of Java SE for enterprises that require both support and specialized tools. The new Advanced Management Console provides a way to monitor and understand client systems at scale. It allows organizations to track usage and more easily create and manage client configuration like Deployment Rule Sets (DRS). DRS can control execution of tracked applications as well as specify compatibility of which application should use which Java SE installation. The new MSI Installer integrates into various desktop management tools, making it easier to customize and roll out different Java SE versions. Advanced Management Console The Advanced Management Console is part of Java SE Advanced designed for desktop administrators, whose users need to run many different Java applications. It provides usage tracking for those Applet & Web Start applications to help identify them for guided DRS creation. DRS can then be verified against the tracked data, to ensure that end-users can run their application against the appropriate Java version with no prompts. Usage tracking also has a different definition for Java SE than it does for most software applications. Unlike most applications where usage can be determined by a simple run-count, Java is a platform used for launching other applications. This means that usage tracking must answer both "how often is this Java SE version used" and "what applications are launched by it." Usage Tracking One piece of Java SE Advanced is a centralized usage tracker. Simply placing a properties file on the client informs systems to report information to this usage tracker, so that the desktop administrator can better understand usage. Information is sent via UDP to prevent any delay on the client. The usage tracking server resides at a central location on the intranet to collect information from those clients. The information is stored in a normalized database for performance, meaning that a single usage tracker can handle a large number of clients. Guided Deployment Rule Sets Deployment Rule Sets were introduced in Java 7 update 40 (September 2013) in order to help administrators control security prompts and guide compatibility. A previous post, Deployment Rule Sets by Example, explains how to configure a rule set so that most applications run against the most secure version but a specific applet may run against the Java version that was current several years ago. There are a different set of questions that can be asked by a desktop administrator in a large or distributed firm: Where are the Java RIAs that our users need? Which RIA needs which Java version? Which users need which Java versions? How do I verify these answers once I have them? The guided deployment rule set creation uses usage tracker data to identify applications both by certificate hash and location. After creating the rules, a comparison tool exists to verify them against the tracked data: If you intend to run an RIA, is it green? If something specific should be blocked, is it red? This makes user-testing easier. MSI Installer The Windows Installer format (MSI) provides a number of benefits for desktop administrators that customize or manage software at scale. Unlike the basic installer that most users obtain from Java.com or OTN, this installer is built around customization and integration with various desktop management products like SCCM. Desktop administrators using the MSI installer can use every feature provided by the format, such as silent installs/upgrades, low-privileged installations, or self-repair capabilities Customers looking for Java SE Advanced can download the MSI installer through their My Oracle Support (MOS) account. Java SE Advanced The new features in Java SE Advanced make it easier for desktop administrators to identify and control client installations at scale. Administrators at organizations that want either the tools or associated commercial support should consider Java SE Advanced.
