  • Host And Expose Application to local small network

    - by tartak
    I developed a little application (web application) using JavaEE+MySql. I try to keep some data and .. from time to time to get some reports using my data. My problem is I have to access this application from 4-5 computers in the office. They are connected through a switch. It's a typical small office network, nothing fancy. I need some advice on how to do this. I mean for a small application with no external communication is it mandatory to use an Apache machine? I'd use a simple Tomcat container on the "server machine" (which is my computer, a windows machine) and .. basically .. I would like to permit the access to my colleagues also. I don't have any knowledge about concurrency (I know mysql permits concurrent access) so I would like some configuration tips also.

  • Internet stops working after heavy downloading, video/audio streaming etc

    - by Kuba Szwed
    As mentioned in title, Internet stops working on my PC after heavy downloading, video/audio streaming etc. There are no errors, no disconnections etc. Simply after some time (certain amount of data downloaded) I can't get any more. If I try using ping afterwards nothing happens. If ping is running simultaneously with streaming/downloading I get some correct responses and then it keeps showing an error. What helps is re-plugging my Pentagram USB wifi card, but I hope there is a better solution. Edit: One more thing: my friend who works in IT suggested that it might have something to do with cache (DNS cache? I don't remember him specifying) getting filled while it should be emptied automatically.

  • How do I fix skype on x86 11.10 desktop which garbles audio both ways in connection with a Windows user?

    - by keepitsimpleengineer
    Strange phenomena ? I have a friend I connect with and talk to regularly occasionally using video. He runs Windows XP with a Logitech webcam and mike. I run Windows XP with a Logitech webcam and mike, and a laptop with built in webcam and mike running both 11.10 x86 Desktop and Windows XP Home. We gab and ogle fine with these. But when I installed 11.10 x86 with GNOME 3.2 dual boot on the same machine with the Logitech webcam and mike, whenever I try to ogle and gab the audio is total garbled. When I make a test call to skype or call somebody on a landline or cell - there's no problem. In summary, everything works except for when running 11.10 x86 GNOME 3.2 connected to his Windows XP. Stumped on this end.

  • XAudio2 - Multiple instances of the same sound

    - by Boreal
    Right now, I'm adding a rudimentary sound engine to my game. So far, I am able to load in a WAV file and play it once, then free up the memory when I close the game. However, the game crashes with a nice ArgumentOutOfBoundsException when I try to play another sound instance. Specified argument was out of the range of valid values. Parameter name: readLength I'm following this tutorial pretty much exactly, but I still keep getting the aforementioned error. Here's my sound-related code. http://pastebin.com/FgaqfXTs The exception occurs on line 156 when I am playing the sound: source.SubmitSourceBuffer(buffer);

  • What is the best way to go about testing that we handle failures appropriately?

    - by Earlz
    we're working on error handling in an application. We try to have fairly good automated test coverage. One big problem though is that we don't really know of a way to test some of our error handling. For instance, we need to test that whenever there is an uncaught exception, a message is sent to our server with exception information. The big problem with this is that we strive to never have an uncaught exception(and instead have descriptive error messages). So, how do we test something what we never want to actually happen?

  • What are some good practices when trying to teach declarative programming to imperative programmers?

    - by ChaosPandion
    I offered to do a little bit training in F# at my company and they seemed to show some interest. They are generally VB6 and C# programmers who don't follow programming with too much passion. That being said I feel like it is easier to write correct code when you think in a functional matter so they should definitely get some benefit out of it. Can anyone offer up some advice on how I should approach this? Ideas Don't focus on the syntax, instead focus on how this language and the idioms it promotes can be used. Try and think of examples that are a pain to write in an imperative fashion but translates to elegant code when written in a declarative fashion.

  • How to remove desktop environments?

    - by MyNameIs...
    I installed few environments that I wanted to try out on Ubuntu 12.04, but none of them worked at all. It could be that I installed them all at the same time, meaning the OS didn't get a chance to work everything out, but either way, they didn't work. I would now like to remove them. The one's that I installed are Fluxbox, OpenBox, XFCE, and MATE. I installed them through the help of this site. Everything seemed to have been working properly until I actually tried to use the shells and nothing loaded at all. Except for Fluxbox, I think that one worked. I want to know of any way to repair or perhaps just remove the packages entirely. I might have already removed them because I did the apt-get remove command on all of them, but they were still in the list on the login screen.

  • Using a :default for file names on include templates in SMARTY 3 [closed]

    - by Yohan Leafheart
    Hello everyone, Although I don't think the question was as good as it could be, let me try to explain better here. I have a site using SMARTY 3 as the template system. I have a template structure similar to the below one: /templates/place1/inner_a.tpl /templates/place1/inner_b.tpl /templates/place2/inner_b.tpl /templates/place2/inner_c.tpl /templates/default/inner_a.tpl /templates/default/inner_b.tpl /templates/default/inner_c.tpl These are getting included on the parent template using {include file="{$temp_folder}/{$inner_template}"} So far great. What I wanted to do is having a default for, in the case that the file "{$temp_folder}/{$inner_template}" does not exists, it uses the equivalent file at "default/{$inner_template}". i.e. If I do {include file="place1/inner_c.tpl"}, since that file does not exists it in fact includes "default/inner_c.tpl" Is it possible?

  • IL and case-sensitivity

    - by Ali .NET
    Quoted from A Brief Introduction To IL code, CLR, CTS, CLS and JIT In .NET CLS stands for Common Language Specifications. It is a subset of CTS. CLS is a set of rules or guidelines which if followed ensures that code written in one .NET language can be used by another .NET language. For example one rule is that we cannot have member functions with same name with case difference only i.e we should not have add() and Add(). This may work in C# because it is case-sensitive but if try to use that C# code in VB.NET, it is not possible because VB.NET is not case-sensitive. Based on above text I want to confirm two points here: Does the case-sensitivity of IL is a condition for member functions only, and not for member properties? Is it true that C# wouldn't be inter-operable with VB.NET if it didn't take care of the case sensitivity?

  • How to write good code with new stuff?

    - by Reza M.
    I always try to write easily readable code that is well structured. I face a particular problem when I am messing around with something new. I keep changing the code, structure and so many other things. In the end, I look at the code and am annoyed at how complicated it became when I was trying to do something so simple. Once I've completed something, I refactor it heavily so that it's cleaner. This occurs after completion most of the time and it is annoying because the bigger the code the more annoying it is the rewrite it. I am curious to know how people deal with such agony, especially on big projects shared between many people ?

  • What is the etiquette in negotiating payment for a software development job

    - by EpsilonVector
    The reason I'm taking a general business question and localize it to software development is that I'm curious as to whether there are certain trends/etiquette/nuances that are typical to our industry. For example, I can imagine two different attitudes employers may generally have to payment negotiations: 1) we'll give you the best offer so we can't really be flexible about it because we already pretty much gave you everything we can give you, or 2) we'll give him an average offer and give in to a better one if forced to. If you try to play hard ball in the first attitude it'll probably cost you the job because you ask for more than they can give you, however if you don't insist on better payment in the second one you'll get a worse offer. In short, when applying to a typical job in our industry what are the typical attitudes from employers on the offers they give, what is the correct way to ask for a better payment, do these things differ between different types of companies (for example startups vs well entrenched companies), and how do these things differ between different kinds of applicants (graduate vs student)?

  • What are the most commonly used enterprise Java technologies, and what would you want a non technical audience to understand about them?

    - by overstood
    I have been asked to give a presentation to a non-technical audience on what Java technologies are currently being used in the enterprise world. The goal is to give this non-technical audience the background they need to understand what engineers are talking about. It's part of a broader series of talks that I'm giving. I'm primarily a .NET and C++ dev, so I thought I'd try to get some input from some Java devs. What technologies do you use? What Java related acronyms would you like to be able to use around non-coders? What would you like non-coders to understand about them?

  • Setup site folders on Apache and PHP [closed]

    - by Cobus Kruger
    I'm trying to set up my first Apache server on my Windows PC at home and I have real trouble finding out which configuration settings go where. I downloaded and installed XAMPP which seemed to get everything nicely set up and can see a working website on http://localhost. So far so good. The point of this is to develop a website of course, and to make my life easier (irony?), I wanted to let the web site root point to my Eclipse project folder. So I opened httpd.conf, uncommented a VirtualHost block and changed its DocumentRoot to my local path. Now when I try to load http://localhost I get a 403 (Access denied) error. So where do I configure permissions for my folder? And is that all I need to let my site run from the folder specified or am I going to have to clear another hurdle?

  • How do i make/setup a mailing list?

    - by acidzombie24
    I know i could program it myself but maybe there is a simple (thats the keyword) package. I like to add a box, snippet, form or page to my site for users to input their email address. Then i'd like it to automatically send email saying you have successfully subscribe. I'd want an unsubscribe link and i would be using smtp on google apps. I would like to send email with html so i can have a simple sentence with a complex link such as this I dont know if i'll get marked as spam if i try to send everyone an email at once? so i'd like the software to manage it. Also i'd like to get the emails in a simple format like csv. Is there a simple app that does this? if not i can write a simple form which does a simple insert (or delete when unsubscribing) and write a 200-300line app to send my emails out for me.

  • Installing on a Lenovo S10-3

    - by Søren Hauberg
    I'm trying to install Ubuntu 10.10 netbook edition on my Lenovo S10-3. According to the release notes, there is a bug in the kernel that forces me to add intel_idle.max_cstate=0 to the kernel parameters. I did this when booting the install CD and I was able to install Ubuntu. During the installation I chose to fetch updates from the net. Now when I try to boot the machine it just hangs. I have tried booting the machine as-is and I have tried adding the above-mentioned kernel parameters. Same experience. So, my questions is how do I install 10.10 in this machine and how do I boot it after I've installed the OS?

  • A Quantity class with units

    - by Ryan Ohs
    Goals Create a class that associates a numeric quantity with a unit of measurement. Provide support for simple arithmetic and comparison operations. Implementation An immutable class (Could have been struct but I may try inheritance later) Unit is stored in an enumeration Supported operations: Addition w/ like units Subtraction w/ like units Multiplication by scalar Division by scalar Modulus by scalar Equals() >, >=, <, <=, == IComparable ToString() Implicit cast to Decimal The Source The souce can be downloaded from Github. Notes This class does not support any arithmetic that would modify the unit. This class is not suitable for manipulating currencies. Future Ideas Have a CompositeQuantity class that would allow quantities with unlike units to be combined. Similar currency class with support for allocations/distributions. Provide conversion between units. (Actually I think this would be best placed in an external service. Many situations I deal with require some sort of dynamic conversion ratio.)

Ubuntu loads fine, everytime but windows goes back. Here is the boot script info. http://paste.ubuntu.com/6405545/ Any help would be appreciated. I want to leave windows behind but still need it for some things on this machine.

  • SQLAuthority News – Great Time Spent at Great Indian Developers Summit 2014

    - by Pinal Dave
    The Great Indian Developer Conference (GIDS) is one of the most popular annual event held in Bangalore. This year GIDS is scheduled on April 22, 25. I will be presented total four sessions at this event and each session is very different from each other. Here are the details of four of my sessions, which I presented there. Pluralsight Shades This event was a great event and I had fantastic fun presenting a technology over here. I was indeed very excited that along with me, I had many of my friends presenting at the event as well. I want to thank all of you to attend my session and having standing room every single time. I have already sent resources in my newsletter. You can sign up for the newsletter over here. Indexing is an Art I was amazed with the crowd present in the sessions at GIDS. There was a great interest in the subject of SQL Server and Performance Tuning. Audience at GIDS I believe event like such provides a great platform to meet and share knowledge. Pinal at Pluralsight Booth Here are the abstract of the sessions which I had presented. They were recorded so at some point in time they will be available, but if you want the content of all the courses immediately, I suggest you check out my video courses on the same subject on Pluralsight. Indexes, the Unsung Hero Relevant Pluralsight Course Slow Running Queries are the most common problem that developers face while working with SQL Server. While it is easy to blame SQL Server for unsatisfactory performance, the issue often persists with the way queries have been written, and how Indexes has been set up. The session will focus on the ways of identifying problems that slow down SQL Server, and Indexing tricks to fix them. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. Indexes are the most crucial objects of the database. They are the first stop for any DBA and Developer when it is about performance tuning. There is a good side as well evil side to indexes. To master the art of performance tuning one has to understand the fundamentals of indexes and the best practices associated with the same. We will cover various aspects of Indexing such as Duplicate Index, Redundant Index, Missing Index as well as best practices around Indexes. SQL Server Performance Troubleshooting: Ancient Problems and Modern Solutions Relevant Pluralsight Course Many believe Performance Tuning and Troubleshooting is an art which has been lost in time. However, truth is that art has evolved with time and there are more tools and techniques to overcome ancient troublesome scenarios. There are three major resources that when bottlenecked creates performance problems: CPU, IO, and Memory. In this session we will focus on High CPU scenarios detection and their resolutions. If time permits we will cover other performance related tips and tricks. At the end of this session, attendees will have a clear idea as well as action items regarding what to do when facing any of the above resource intensive scenarios. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. To master the art of performance tuning one has to understand the fundamentals of performance, tuning and the best practices associated with the same. We will discuss about performance tuning in this session with the help of Demos. Pinal Dave at GIDS MySQL Performance Tuning – Unexplored Territory Relevant Pluralsight Course Performance is one of the most essential aspects of any application. Everyone wants their server to perform optimally and at the best efficiency. However, not many people talk about MySQL and Performance Tuning as it is an extremely unexplored territory. In this session, we will talk about how we can tune MySQL Performance. We will also try and cover other performance related tips and tricks. At the end of this session, attendees will not only have a clear idea, but also carry home action items regarding what to do when facing any of the above resource intensive scenarios. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. To master the art of performance tuning one has to understand the fundamentals of performance, tuning and the best practices associated with the same. You will also witness some impressive performance tuning demos in this session. Hidden Secrets and Gems of SQL Server We Bet You Never Knew Relevant Pluralsight Course SQL Trio Session! It really amazes us every time when someone says SQL Server is an easy tool to handle and work with. Microsoft has done an amazing work in making working with complex relational database a breeze for developers and administrators alike. Though it looks like child’s play for some, the realities are far away from this notion. The basics and fundamentals though are simple and uniform across databases, the behavior and understanding the nuts and bolts of SQL Server is something we need to master over a period of time. With a collective experience of more than 30+ years amongst the speakers on databases, we will try to take a unique tour of various aspects of SQL Server and bring to you life lessons learnt from working with SQL Server. We will share some of the trade secrets of performance, configuration, new features, tuning, behaviors, T-SQL practices, common pitfalls, productivity tips on tools and more. This is a highly demo filled session for practical use if you are a SQL Server developer or an Administrator. The speakers will be able to stump you and give you answers on almost everything inside the Relational database called SQL Server. I personally attended the session of Vinod Kumar, Balmukund Lakhani, Abhishek Kumar and my favorite Govind Kanshi. Summary If you have missed this event here are two action items 1) Sign up for Resource Newsletter 2) Watch my video courses on Pluralsight Reference: Pinal Dave (http://blog.sqlauthority.com)Filed under: MySQL, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQLAuthority Author Visit, SQLAuthority News, T SQL Tagged: GIDS

  • Should security updates 'always' be installed?

    - by kmansoor
    We are a small shop, no real sysadmin. So developers (Java EE) also try to maintain Ubuntu server 12.0.4. When I login a terminal and I see messages like: 6 packages can be updated. 6 updates are security updates. Should all security updates always be installed? can some be ignored? Should these be acted upon immediately? Or one could wait for 2:00 AM coming Sunday? Is there a way to know a 'critical' update? Is there a good sysadmin for dummies resource I should be reading?
