  • Forwarding data between two interfaces

    - by user84471
    I installed Ubuntu server 12.04 after that I installed dhcp3-server and configured it like this: At isc-dhcp-server INTERFACES="eth0" And in dhcpd.conf # A slightly different configuration for an internal subnet. subnet 192.168.1.0 netmask 255.255.255.0 { range 192.168.1.5 192.168.1.100; option domain-name-servers 192.168.1.1; option domain-name "nazwa.local"; option routers 192.168.1.1; option broadcast-address 192.168.1.255; default-lease-time 600; max-lease-time 7200; } Also I have two eth interfaces: # second netowrk interface auto eth0 iface eth0 inet static address 192.168.1.1 netmask 255.255.255.0 # The primary network interface auto eth1 iface eth1 inet dhcp When I plug computer to eth0 I get propertly ip adress but I can't visit any sites. I do even this: echo 1 > /proc/sys/net/ipv4/ip_forward

  • Joomla: Prevent certain user from visiting a certain page

    - by MrB
    I have an internal section in my Joomla only for "Registered" users. There they can edit preferences. Multiple users can access the same preferences (different stakeholders). Now I have "smithcorp" and "smithcorp_guest". They should both be able to view the same things, but "smithcorp_guest" shouldn't be able to edit the preferences. Is there a way to forbid "smithcorp_guest" access to this page? I have only seen access regulation via the user level, i.e. unregistered, registered, admin. Thanks, MrB

  • Google Analytics - bad experiences? (esp. adult content)

    - by Litso
    I work for a rather large adult website, and we're currently not using Google Analytics. There is an internal debate going on about whether we should start using Analytics, but there is hestitation from certain parties. The main argument is that they fear that Google will get too much insight into our website, and might even block us from the index as a result based on our adult content. Has anyone here ever had such an experience, or know stories about bad experiences with Google Analytics in such a manner? I personally think it will only improve our website if we were able to use Analytics, but the dev team was asked to look into possible negative effects. Any help would be appreciated.

  • No options for sound output

    - by Chef Flambe
    Newbie here. Trying out Ubuntu for kicks. I have a 10.04 Ubuntu system dual booting on my Windows 7 laptop, fully updated, an Asus A53S. I have an external Samsung monitor/tv hooked up via HDMI. I'm getting sound from the external monitor fine when using Win7 but can't get anything with Ubuntu. I've read threads here about similar stuff and they say go check my sound options but I don't have any additional options than the one listed - Internal Audio. What else can I check/do?

  • Partial Function Application

    - by AngelEyes
    This is long overdo... Just a short and simple example of Partial Function Application.   For some good explanations, which also include the difference between Currying and Partial Function Application, check out: http://msmvps.com/blogs/jon_skeet/archive/2012/01/30/currying-vs-partial-function-application.aspx and also this answer on stackoverflow: http://stackoverflow.com/a/8826698/532517   And here is the example, taken from real code:           internal void Addfile(string parentDirName, string fileName, long size)         {             AddElement(parentDirName, fileName, (name, parent) => new File(name, size, parent));         }           public void AddDir(string parentDirName, string dirName)         {             AddElement(parentDirName, dirName, (name, parent) => new Directory(dirName, parent));         }           private void AddElement(string parentDirName, string name,                                 Func<string, FileSystemElement, FileSystemElement> elementCreator)         {             ValidateFileNames(parentDirName, name);             var parent = (Directory)_index[parentDirName];             FileSystemElement element = elementCreator(name, parent);             parent._elements.Add(element);             _index.Add(name, element);         }

  • State of the (Commerce) Union: What the healthcare.gov hiccups teach us about the commerce customer experience

    - by Katrina Gosek
    Guest Post by Brenna Johnson, Oracle Commerce Product A lot has been said about the healthcare.gov debacle in the last week. Regardless of your feelings about the Affordable Care Act, there’s a hidden issue in this story that most of the American people don’t understand: delivering a great commerce customer experience (CX) is hard. It shouldn’t be, but it is. The reality of the government’s issues getting the healthcare site up and running smooth is something we in the online commerce community know too well.  If there’s one thing the botched launch of the site has taught us, it’s that regardless of the size of your budget or the power of an executive with a high-profile project, some of the biggest initiatives with the most attention (and the most at stake) don’t go as planned. It may even give you a moment of solace – we have the same issues! But why?  Organizations engage too many separate vendors with different technologies, running sections or pieces of a site to get live. When things go wrong, it takes time to identify the problem – and who or what is at the center of it. Unfortunately, this is a brittle way of setting up a site, making it susceptible to breaks, bugs, and scaling issues. But, it’s the reality of running a site with legacy technology constraints in today’s demanding, customer-centric market. This approach also means there’s also a lot of cooks in lots of different kitchens. You’ve got development and IT, the business and the marketing team, an external Systems Integrator to bring it all together, a digital agency or consultant, QA, product experts, 3rd party suppliers, and the list goes on. To complicate things, different business units are held responsible for different pieces of the site and managing different technologies. And again – due to legacy organizational structure and processes, this is all accepted as the normal State of the Union. Digital commerce has been commonplace for 15 years. Yet, getting a site live, maintained and performing requires orchestrating a cast of thousands (or at least, dozens), big dollars, and some finger-crossing. But it shouldn’t. The great thing about the advent of mobile commerce and the continued maturity of online commerce is that it’s forced organizations to think from the outside, in. Consumers – whether they’re shopping for shoes or a new healthcare plan – don’t care about what technology issues or processes you have behind the scenes. They just want it to work.  They want their experience to be easy, fast, and tailored to them and their needs – whatever they are. This doesn’t sound like a tall order to the American consumer – especially since they interact with sites that do work smoothly.  But the reality is that it takes scores of people, teams, check-ins, late nights, testing, and some good luck to get sites to run, and even more so at Black Friday (or October 1st) traffic levels.  The last thing on a customer’s mind is making excuses for why they can’t buy a product – just get it to work. So what is the government doing? My guess is working day and night to get the site performing  - and having to throw big money at the problem. In the meantime they’re sending frustrated online users to the call center, or even a location where a trained “navigator” can help them in-person to complete their selection. Sounds a lot like multichannel commerce (where broken communication between siloed touchpoints will only frustrate the consumer more). One thing we’ve learned is that consumers spend their time and money with brands they know and trust. When sites are easy to use and adapt to their needs, they tend to spend more, come back, and even become long-time loyalists. Achieving this may require moving internal mountains, but there’s too much at stake to ignore the sea change in how organizations are thinking about their customer. If the thought of re-thinking your internal teams, technologies, and processes sounds like a headache, think about the pain associated with losing valuable customers – and dollars. Regardless if you’re in B2B or B2C, it’s guaranteed that your competitors are making CX a priority. Those early to the game who have made CX a priority have already begun to outpace their competition. So as you’re planning for 2014, look to the news this week. Make sure the customer experience is a focus at your organization. Expectations are at record highs. Map your customer’s journey, and think from the outside, in. How easy is it for your customers to do business with you? If they interact with many touchpoints across your organization, are the call center, website, mobile environment, or brick and mortar location in sync? Do you have the technology in place to achieve this? It’s time to give the people what they want!

  • GPG Workflow in 11.04

    - by Ross Bearman
    At work we handle the transfer of small bits of sensitive data with GPG, usually posted on a secure internal website. Until Firefox 4 was released, we used FireGPG for inline decryption; however the IPC libraries that it relied upon were no longer present in FF4, making it unusable and it will no longer install in FF5. Currently I'm manually pasting the GPG blocks into a text file, then using the Nautilus context-menu plugin or the command line to decrypt the contents of the file. When we're handling large amount of these small files throughout the day this starts to become a real chore. I've looked around but can't seem to find much information on useful GPG clients in Ubuntu. A client that allowed me to paste in a GPG block and instantly decrypt it, and also paste in plaintext and easily encrypt it for multiple recipients would be ideal. So my question is does this exist? I can't seem to find anything about this with obvious searches on Google, so hopefully someone here can help, or offer an alternative workflow.

  • Reasons to disable game save during combat (e.g. Mass Effect 2)

    - by Steve V.
    So I've been playing Mass Effect 2 (PC) and one of the things I've noticed is that you can only save your game when you're not engaged in combat. As soon as the first enemy shows up on your radar, the save button is disabled. Once combat is over, save functionality reappears. It seems reasonable to assume that Mass Effect 2 is a state machine, and therefore, the internal state of the program at any moment can be captured and reloaded later. This is basically a solved problem - games have been designed this way since the Half-Life era. It also seems reasonable to assume that BioWare knew what they were doing when they made the decision not to follow this model - it's a tried and true system; BioWare wouldn't have done it the way they did without some good reason. What reasons are there to disable game save functionality during combat?

  • SQL Server 2012 Service Pack 1 is available - this time for sure!

    - by AaronBertrand
    Last week I mentioned in passing that Service Pack 1 is now available, while I was blogging from the PASS Summit keynote .

  • What is Google's repository like?

    - by Ricket
    I heard Google has a giant private (internal) repository of all of their code and their employees have access to it so that when they are developing things they don't have to reinvent the wheel. I'd like to know more about it! Is there anyone here from Google that can describe it in a bit more detail, or do you know a bit more about it? I'm interested in knowing mainly about how it's organized and how they can make it easy for an employee to find something in such a giant codebase as it must be.

  • Getting Started with Component Architecture: DI?

    - by ashes999
    I just moved away from MVC towards something more component-architecture-like. I have no concept of messages yet (it's rough prototype code), objects just get internal properties and values of other classes for now. That issue aside, it seems like this is turning into an aspect-oriented-programming challenge. I've noticed that all entities with, for example, a position component will have similar properties (get/set X/Y/Z, rotation, velocity). Is it a common practice, and/or good idea, to push these behind an interface and use dependency injection to inject a generic class (eg. PositionComponent) which already has all the boiler-plate code? (I'm sure the answer will affect the model I use for message/passing)

  • Can't read CDs, can't create USB... how do I install Ubuntu?

    - by user68080
    Hello everyone and thank you in advance for your time. I have troubles with the latest Ubuntu distribution: since I upgraded to 12.04 Ubuntu has started having troubles (internal errors, packages that crash repeatedly, I can't install new packages, Ubuntu Software Center crashes, Java apps that worked stopped working and display weird mistakes, files were corrupted... a mess). I ultimately decided to format everything and install 12.04 from scratch. I made a backup and everything, but now I have troubles installing ubuntu 12.04. Specifically, a CD I burned with Brasero that works on another PC is not read by my laptop (not at boot phase, nor inside Ubuntu), and when I try to create a USB with Ubuntu (following the instructions I found on the ubuntu site) Startup Disk Creator stops at 22% saying that "the codes do not match". Any idea on what to do next? No, I can't buy a new PC.

  • SPARC T5-4 Engineering Simulation Solution

    - by Mike Mulkey-Oracle
    A recent Oracle internal performance evaluation for computer-based product design demonstrated that Oracle's SPARC T5-4 server running MSC's SimManager simulation software with Oracle Database 12c consolidates the work of multiple x86 servers while delivering better overall performance.   Engineering simulation solutions have taken the center stage in helping companies design and develop innovative products while reducing physical prototyping costs, and exploring a larger design space, resulting in more design possibilities. For this solution, a single SPARC T5-4 server running Oracle Solaris 11 was deployed to consolidate the MSC SimManager server, the Oracle Database 12c server, and the web application server onto a single platform. An automotive design workload was deployed to demonstrate how the SPARC T5-4 server can be used to consolidate the work of multiple x86 servers and deliver better overall performance while reducing complexity and achieving optimal product designs.  A joint Oracle/MSC Software solution brief describes this in more detail:  A Simplified Solution for Product Lifecycle Management —MSC SimManager on a SPARC T5-4 Server

  • What things to take into consideration when refactoring code?

    - by JustaPro
    Code refactoring is a "disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior" Could anyone explain this definition? I find it kind of blurry. Which is the best technique to do it? Are these the only ones? Which are the obstacles one would meet when refactoring code? What to take into consideration when switching between IDEs? Do tools which help refactoring exist? If yes, which one would you recommend using? Any references to links where I can find out more on this subject or to books that have been written are welcomed. The questions above are for any programming language, but specific examples are appreciated. Anything that would clarify this for me is.

  • Hash Function Added To The PredicateEqualityComparer

    - by Paulo Morgado
    Sometime ago I wrote a predicate equality comparer to be used with LINQ’s Distinct operator. The Distinct operator uses an instance of an internal Set class to maintain the collection of distinct elements in the source collection which in turn checks the hash code of each element (by calling the GetHashCode method of the equality comparer) and only if there’s already an element with the same hash code in the collection calls the Equals method of the comparer to disambiguate. At the time I provided only the possibility to specify the comparison predicate, but, in some cases, comparing a hash code instead of calling the provided comparer predicate can be a significant performance improvement, I’ve added the possibility to had a hash function to the predicate equality comparer. You can get the updated code from the PauloMorgado.Linq project on CodePlex,

  • Temenos WealthManager: performance benchmark on Exadata

    - by Javier Puerta
    Temenos WealthManager is at work in financial institutions of all sizes. No matter the size, each of Temenos’ customers has one requirement in common: a need for fast technology. This led Temenos to conduct a performance benchmark, running its WealthManager platform on Oracle Exadata Database Machine. During the study, Temenos executed high-intensity financial engines two- to three-times faster than its previous internal benchmarks and/or largest customer throughput. The company also demonstrated greater than two-times the average improvement in response times for six-times the number of users and data volumes. Further, Temenos secured a two-times gain in service-level agreements for batch and user-oriented workloads via dedicated or parallelized processing windows. Last year Temenos also communicated the availability of its T24 core banking system and how the benchmark run demonstrated the ability of Oracle’s Exadata platform to comfortably support the highest banking volumes for T24.

  • GUI won't load, but the desktop background loads. Can't access the terminal

    - by Mickeysofine
    Having trouble with the Ubuntu GUI. I can log in just fine (see this)... everything looks normal there. But as soon as I put in my password, I get this. I tried a few different troubleshooting keyboard commands (ctrl+alt+t, crtl+alt+delete), and only the latter worked. I can interact with that window just fine, except I am unable to resize or move it. The first time I logged in, I got a dialog box that said, "Ubuntu has experienced an internal error. Send error report?" Doesn't say anything now. Yes I tried restarting it. Thanks a bunch, Michael EDIT: Trying to start a guest session leads to the same problem.

  • Collapsible menu and amount of links in a web page

    - by dstonek
    One of my pages contain three levels of a collapsible menu (JS + CSS from mycssmenu.com). There are a dozen first level items displayed to users, each one with various second level items, and finally a lot of third level items, each one containing a related link. This generates a lot of internal links (300+). Because of SEO should I change the way the collapsible menu is displayed to reduce link amount? What do you suggest? I would like to avoid users to have to open a new page just to only see what are third level items and eventually follow one of its links.

I can't reproduce the problem, but it's apparently affecting client for the last month. I've suggested: Reloading IE8 Checking Internet Permissions Flushing the cache I'm not really certain what direction to search for the answer. Is it likely to be a server permissions issue? a VPN connection issue? a rare ie8 CSS bug?

  • What is the best way to learn C# programming? [closed]

    - by MSU
    My case I want to get the capability of doing anything in C# from building applications to solving problems. I searched for and tried to read books. Then one of the experts said that reading books will not make any good and that to learn, you have to solve real world problems in C#, and he gave me some problems which I previously solved in C++. The thing is that while I know the internal logic of solving the problem, I don't know how to implement it using C# efficiently. I know the message to pass but not the exact way to pass it. I did a program to solve a problem, then find out there are much easier ways of doing it wherever I was doing it in tougher way. What I need to get hold of the language and get the ability to code in C# proficiently?

Every change freezes the screen, I can't save anything... I'm talking of complex documents, with lots of internal references and footnotes and some propor text styles of about 230 pages (phd work) I wanted to alert you that probabely something is wrong but as I don't have any tecnical knowledge, I don't know what could be usefull to help you in your great job of making good free software. My little desktop has 2Gb of Ram memory and an atom processor (I can look for more details if that would be usefull to you)
