  • Looking for enterprise web application design inspiration

    - by Farshid
    I've checked many websites to be inspired about what the look and feel of a serious enterprise web-application should look like. But the whole I saw were designed for being used by single users and not serious corporate users. The designs I saw were mostly happy-colored, and looked like being developed by a small team of eager young passionate developers. But what I'm looking for, are showcases of serious web apps' designs (e.g. web apps developed by large corporations) that are developed for being used by a large number of corporate uses. Can you suggest me sources for this kind of inspiration?

  • Using Hadooop (HDInsight) with Microsoft - Two (OK, Three) Options

    - by BuckWoody
    Microsoft has many tools for “Big Data”. In fact, you need many tools – there’s no product called “Big Data Solution” in a shrink-wrapped box – if you find one, you probably shouldn’t buy it. It’s tempting to want a single tool that handles everything in a problem domain, but with large, complex data, that isn’t a reality. You’ll mix and match several systems, open and closed source, to solve a given problem. But there are tools that help with handling data at large, complex scales. Normally the best way to do this is to break up the data into parts, and then put the calculation engines for that chunk of data right on the node where the data is stored. These systems are in a family called “Distributed File and Compute”. Microsoft has a couple of these, including the High Performance Computing edition of Windows Server. Recently we partnered with Hortonworks to bring the Apache Foundation’s release of Hadoop to Windows. And as it turns out, there are actually two (technically three) ways you can use it. (There’s a more detailed set of information here: http://www.microsoft.com/sqlserver/en/us/solutions-technologies/business-intelligence/big-data.aspx, I’ll cover the options at a general level below)  First Option: Windows Azure HDInsight Service  Your first option is that you can simply log on to a Hadoop control node and begin to run Pig or Hive statements against data that you have stored in Windows Azure. There’s nothing to set up (although you can configure things where needed), and you can send the commands, get the output of the job(s), and stop using the service when you are done – and repeat the process later if you wish. (There are also connectors to run jobs from Microsoft Excel, but that’s another post)   This option is useful when you have a periodic burst of work for a Hadoop workload, or the data collection has been happening into Windows Azure storage anyway. That might be from a web application, the logs from a web application, telemetrics (remote sensor input), and other modes of constant collection.   You can read more about this option here:  http://blogs.msdn.com/b/windowsazure/archive/2012/10/24/getting-started-with-windows-azure-hdinsight-service.aspx Second Option: Microsoft HDInsight Server Your second option is to use the Hadoop Distribution for on-premises Windows called Microsoft HDInsight Server. You set up the Name Node(s), Job Tracker(s), and Data Node(s), among other components, and you have control over the entire ecostructure.   This option is useful if you want to  have complete control over the system, leave it running all the time, or you have a huge quantity of data that you have to bulk-load constantly – something that isn’t going to be practical with a network transfer or disk-mailing scheme. You can read more about this option here: http://www.microsoft.com/sqlserver/en/us/solutions-technologies/business-intelligence/big-data.aspx Third Option (unsupported): Installation on Windows Azure Virtual Machines  Although unsupported, you could simply use a Windows Azure Virtual Machine (we support both Windows and Linux servers) and install Hadoop yourself – it’s open-source, so there’s nothing preventing you from doing that.   Aside from being unsupported, there are other issues you’ll run into with this approach – primarily involving performance and the amount of configuration you’ll need to do to access the data nodes properly. But for a single-node installation (where all components run on one system) such as learning, demos, training and the like, this isn’t a bad option. Did I mention that’s unsupported? :) You can learn more about Windows Azure Virtual Machines here: http://www.windowsazure.com/en-us/home/scenarios/virtual-machines/ And more about Hadoop and the installation/configuration (on Linux) here: http://en.wikipedia.org/wiki/Apache_Hadoop And more about the HDInsight installation here: http://www.microsoft.com/web/gallery/install.aspx?appid=HDINSIGHT-PREVIEW Choosing the right option Since you have two or three routes you can go, the best thing to do is evaluate the need you have, and place the workload where it makes the most sense.  My suggestion is to install the HDInsight Server locally on a test system, and play around with it. Read up on the best ways to use Hadoop for a given workload, understand the parts, write a little Pig and Hive, and get your feet wet. Then sign up for a test account on HDInsight Service, and see how that leverages what you know. If you're a true tinkerer, go ahead and try the VM route as well. Oh - there’s another great reference on the Windows Azure HDInsight that just came out, here: http://blogs.msdn.com/b/brunoterkaly/archive/2012/11/16/hadoop-on-azure-introduction.aspx

  • What are fail2ban's log iptables "returned 400" entries?

    - by luri
    In my fail2ban.log there are some entries the meaning of which I don't understand (and haven't found searching around)... For instance, a couple of examples from my log: iptables -I INPUT -p tcp -m multiport --dports ssh -j fail2ban-ssh-ddos returned 400 ... iptables -I INPUT -p tcp -m multiport --dports http,https -j fail2ban-apache-overflows returned 400 So my questions would be: Are those lines errors? If they are... is it a fail2ban problem or an iptables one? If they are.... what do those errors mean?... and... how can they be avoided (if they have to)?

  • gnome-shell failed to launch when dual monitor detected, nvidia card

    - by Terry Hu
    I installed a clean precise. I like gnome-shell so I installed it. It worked well with single monitor. But It does not work well when I go to office, plug my external monitor onto my laptop. I am using nvidia driver. Another colleague is using the same laptop, he can work well with dual monitors. His laptop is ATI graphic card. When I plug my extended monitor cable, I choose GNOME, but actually it goes to gnome 2 classic desktop environment, not GNOME 3. When I disconnect the extended monitor, restart X, I can login with GNOME3. Do I have to choose between GNOME3 and extended monitor? It's a hard choose.

  • Desktop shortcut to create a new desktop shortcut doesn't do anything

    - by David M. Karr
    It's weird that creating desktop shortcuts is currently so primitive. I found the following: Create Shortcut / launcher on Desktop in Ubuntu 12.04 That helps. However, if there's something wrong with the shortcut, it just doesn't do anything. For instance, I tried to create a shortcut for this command line to create a shortcut. When I double-click it, it just does nothing. This is the resulting text of my "Create Desktop Shortcut.desktop" file on the desktop: [Desktop Entry] Version=1.0 Type=Application Terminal=false Icon[en_CA]=gnome-panel-launcher Exec=/usr/bin/gnome-desktop-item-edit ~/Desktop/ --create-new Name[en_CA]=Create Desktop Shortcut Name=Create Desktop Shortcut Icon=gnome-panel-launcher As I said, when I double-click this, or right-click it and select Open, nothing happens. Is there a log file where something about this would be written to?

  • Automated deployment/installation of development tools

    - by thegreendroid
    My team is looking to automate installation/deployment of all of our development tools. The main driver for this is to ensure that everyone in the team has a consistent development environment setup and to also allow a new recruit to get up and running easily. By development environment I mean tools like SCM, toolchains, IDEs etc. and by consistent I mean everyone using the same version of compiler to build code (this is very important!). Here are a few of our requirements – Allow unattended (silent) install of our entire dev setup by running a single script Ability to deploy selective updates (new versions) for specific tools Ability to report which tools are installed and their specific version numbers Must work on Windows (Linux would be a bonus) Must be easy to maintain What are some of the tools that you've used to automate such a task?

  • Run virtualbox in other X session

    - by Valicek1
    I'm running ubuntu on my laptop (host). Inside ubuntu, there is running one instance of virtualbox. (where is installed MS Windows). My idea is to run virtualbox in separate X session (something like multiuser). If it is not clear, i'll try to explain... When I want to visit tty1, I'll press CTRL+ALT+F1. To return to my Unity desktop, I'm gona use CTRL+ALT+F7... And here comes what I need. After pressing CTRL+ALT+F8 show fullscreen virtualbox windows system, just to switch as ttys.. I am using Ubuntu 14.10. I have wasted hours by using google to find some solution, but my biggest prolem is I cannot name the problem.

  • XAML2CPP 1.0.1.0

    - by Valter Minute
    I upgraded XAML2CPP to fix some bugs and support some new features that will be used in my next tutorial step (that I hope to publish very soon!). Bug fixed: the listbox selection changed event was generated with an incorrect prototype events generated by the XAML tree root element (UserControl) were not handled. New features: XAML2CPP generates panels (dynamically generated XAML subtrees that may be added to a page) and user controls (those will be the object of my next post, stay tuned!). XAML2CPPXRValue class has been added to XAML2CPPbase.h. This class will allow single-line declaration of XRValue objects (I’m lazy!) and destroys automatically objects and string XRValues when the object itself is destroyed. You can download the latest XAML2CPP release here: http://cid-9b7b0aefe3514dc5.skydrive.live.com/self.aspx/.Public/XAML2CPP.zip

  • Cannot boot from USB disk with "not a COM32R image" error

    - by Siva Prasad Varma
    After installing 11.10 on my Dell Studo 15 (Model 1557) laptop, it started to overheat. Recently it even shutdown twice saying that critical temperature has reached even when I was just idling (not even a single program was open except for Firefox). After learning that it is a problem with 3.0.0 kernel I decided to roll back to 10.04 LTS. I have downloaded the most recent 10.04 iso from ubuntu.com and created a live USB using startup disk creator in 11.10. But when I am trying to boot from USB I am getting the following error vesamenu.c32: not a COM32R image I have installed ubuntu from usb stick a couple of dozen times before this and I think it is not a problem with my hardware. Please tell me what to do.

  • Change permission for ALL folders and files

    - by Xweque
    I've been around Ubuntu for not too long now and I'm getting tired of a thing I used to accept. When I installed Apache and PHP on Ubuntu it was done with root meaning it got permission. So I changed that to me. Now I've just copied a big number of files, (PHP), to be viewed and edited in these directories. Now my problem: I can not view the files from var/www/ because it requires, for some reason, everyone to have access to the files. Not only me, or my group but everyone. No one else is using the computer but me, so I'm cool with it. Though I need a command to change ALL files permission recursively. When I've browsed the questions already been answered I find for example chown -R viktor:viktor /var/www/, or using sudo as well. This worked on the single var/www and the folders inside but not the files inside the folders and very odd I notice I can't do the same thing on example /var/www/dev/.

  • Reusing WCF Proxy to reduce Memory Usage

    - by Sudheer Kumar
    I am working on a program that uploads BLOB from DB to a Document Management System. I have a WCF service to interact with the DMS. I have a multi-threaded client program that uploads the BLOBs to DMS and every thread used to create and dispose a proxy instance for every record to update. When I have a large no of records to convert, I found that the tool’s memory foot print keeps increasing. After a little debugging I found that the WCF proxies are the culprits for excessive memory usage. I changed the program to re-use the proxies to the service, having one proxy per thread. So in some scenarios, it might be beneficial to re-use WCF proxies.

  • Video Recorder Tool (Screencast) that is up to date

    - by Luis Alvarado
    I was looking at this post How to create a screencast? which mentions some of the Video Recorders (Screencast) that I was looking for but some of them are more than 8 months old with not one single update made to them. Am looking for a Screencast that is at least update recently and that I know that if I keep using it I could count on it being updated. The most important part is video recording but sound is good too. Maybe a windows area, mouse tracking, etc.. But it needs to be up to date and not abandoned or very old. And of course that works in 11.10 and has in mind to work in 12.04.

  • Does heavy library and snippet codes usage make you a bad programmer?

    - by Henrik P.
    Overall I'm in programming for about 8 years now and it seems to me that I'm relying more and more on open source libraries and snippets (damn you GitHub!) to "get the job done". I know that in time I could write me own implementation but I like to focus on the overall design. Is this normal (non cooperate environment)? Does it make you a bad programmer if "programming" is nothing more than cluing different libraries together. Feels like it. I know about "don't reinvent the wheel" but what happens when you don't invent a single wheel anymore. What's your take on this?

  • Why and when should I make a class 'static'? What is the purpose of 'static' keyword on classes?

    - by Saeed Neamati
    The static keyword on a member in many languages mean that you shouldn't create an instance of that class to be able to have access to that member. However, I don't see any justification to make an entire class static. Why and when should I make a class static? What benefits do I get from making a class static? I mean, after declaring a static class, one should still declare all members which he/she wants to have access to without instantiation, as static too. This means that for example, Math class could be declared normal (not static), without affecting how developers code. In other words, making a class static or normal is kind of transparent to developers.

  • When there's no TCO, when to worry about blowing the stack?

    - by Cedric Martin
    Every single time there's a discussion about a new programming language targetting the JVM, there are inevitably people saying things like: "The JVM doesn't support tail-call optimization, so I predict lots of exploding stacks" There are thousands of variations on that theme. Now I know that some language, like Clojure for example, have a special recur construct that you can use. What I don't understand is: how serious is the lack of tail-call optimization? When should I worry about it? My main source of confusion probably comes from the fact that Java is one of the most succesful languages ever and quite a few of the JVM languages seems to be doing fairly well. How is that possible if the lack of TCO is really of any concern?

  • Efficient visualization of a large voxelized volume

    - by Alejandro Piad
    Lets consider a large voxelized volume stored in an oct-tree or any other convenient structure. This volume represents, for instance, a landscape, where each block is either empty (air), or it has an specific material that will be later used to apply a texture. Voxels that are next to each other represent connected sections of the surface. What I need is an algorithm to generate a mesh from this voxels that represents the volume, with the following caracteristics: All the "holes" in the voxelized volume are correct. All the connections are correct, i.e. seamless. The surface appears smooth. In a broad sense, I want to somehow preserve the surface topology, meaning that connected sections remain connected in the resulting mesh and that the surface has a curvature that responds to the voxels topology. Imagine trying to render the Minecraft world but getting the mountain ladders to be smooth instead of blocky.

  • Which one is better? To have link on one page or on all pages?

    - by Ervin
    I have a website: http://www.amenajari-gradini-mures.ro and I will put links on http://www.casesigradini.ro . I would like to know which one is better from the point of view of SEO: - to have one single link on the homepage OR - to have a link on every page (about 48000 pages) ? Right now I got my link up on every page. But if it's better to have it on one page only (or maybe on few main pages ) then i'll take it out the rest. Please give some arguments for your answers. Thanks

  • Only 192.168.0.3 can request, but anyone can request /public/file.html

    - by mattalexx
    I have the following virtual host on my development server: <VirtualHost *:80> ServerName example.com DocumentRoot /srv/web/example.com/pub <Directory /srv/web/example.com/pub> Order Deny,Allow Deny from all Allow from 192.168.0.3 </Directory> </VirtualHost> The Allow from 192.168.0.3 part is to only allow requests from my workstation machine. I want to tweak this to allow anyone to request a certain URL: http://example.com/public/file.html How do I change this to allow /public/file.html requests to get through from anyone? Note: /public/file.html doesn't actually exist as a file on the server. I redirect all incoming requests through a single index file using mod_rewrite.
