• Optimizing MySQL, Improving Performance of Database Servers

  - by Antoinette O'Sullivan

  Optimization involves improving the performance of a database server and queries that run against it. Optimization reduces query execution time and optimized queries benefit everyone that uses the server. When the server runs more smoothly and processes more queries with less, it performs better as a whole. To learn more about how a MySQL developer can make a difference with optimization, take the MySQL Developers training course. This 5-day instructor-led course is available as: Live-Virtual Event: Attend a live class from your own desk - no travel required.

• I want to build a Virtual Machine, are there any good references?

  - by Michael Stum

  I'm looking to build a Virtual Machine as a platform independent way to run some game code (essentially scripting). The Virtual Machines that I'm aware of in games are rather old: Infocom's Z-Machine, LucasArts' SCUMM, id Software's Quake 3. As a .net Developer, I'm familiar with the CLR and looked into the CIL Instructions to get an overview of what you actually implement on a VM Level (vs. the language level). I've also dabbled a bit in 6502 Assembler during the last year. The thing is, now that I want¹ to implement one, I need to dig a bit deeper. I know that there are stack based and register based VMs, but I don't really know which one is better at what and if there are more or hybrid approaches. I need to deal with memory management, decide which low level types are part of the VM and need to understand why stuff like ldstr works the way it does. My only reference book (apart from the Z-Machine stuff) is the CLI Annotated Standard, but I wonder if there is a better, more general/fundamental lecture for VMs? Basically something like the Dragon Book, but for VMs? I'm aware of Donald Knuth's Art of Computer Programming which uses a register-based VM, but I'm not sure how applicable that series still is, especially since it's still unfinished? Clarification: The goal is to build a specialized VM. For example, Infocom's Z-Machine contains OpCodes for setting the Background Color or playing a sound. So I need to figure out how much goes into the VM as OpCodes vs. the compiler that takes a script (language TBD) and generates the bytecode from it, but for that I need to understand what I'm really doing. ¹ I know, modern technology would allow me to just interpret a high level scripting language on the fly. But where is the fun in that? :) It's also a bit hard to google because Virtual Machines is nowadays often associated with VMWare-type OS Virtualization...

• Best way to use GIT to maintain web application template

  - by Darren

  I am a sole developer and I have a web application template that I have created in Visual Studio. I am using GIT for source control, but only on my development machine. Presently I have a master and I create branches for new features, merging them back in to the master as I complete the features. I am at a point now where I am ready to use the template for deployments, and of course I want to continue adding new features via branching/merging. My question is: what would be the typical/recommended way for me to create application deployments based on the master? Should I clone the repository into a new directory that is for a particular web application? Or should I also use branching to do project development based on the main project? The projects would never be merged back into the master. However, it would be nice if I could merge future features into the master and have the ability to incorporate them into previously completed projects if desired. For more specific details of my environment: I am using TortoiseGIT in Windows 7, Visual Studio 2012, ASP.NET Web Pages. Obviously the main differences between deployments would simply be differing pages, CSS files and jQuery scripts. I found this post as I was writing this one. In order to do this should I clone the master repository and checkout from it?

• Why ADF Developers Should Attend ODTUG This Year

  - by shay.shmeltzer

  If you are using Oracle ADF or planning to pick it up in the next year, I would encourage you to try and attend this year's ODTUG K-Scope conference. If you are not familiar with it, ODTUG - the Oracle Development Tools User Groups - holds a yearly conference that is very technical in nature. It is not a huge conference in terms of the number of attendees, but this just means that you have more opportunities to interact with Oracle ACEs, Oracle Product Managers, and other developers. The conference is known to be a no-fluff, no-marketing, technical conference. This year however there is one key new thing that should be of interest to readers of this blog. A new track called the "Fusion Middleware" track has been formed and it has lots of sessions for any level of ADF developer. The track is run by several Oracle ACEs who are also involved in the ADF Enterprise Methodology Group. They have sessions for every level of ADF awareness - from the beginner to the expert, and you can also learn about related technologies such as WebCenter and SOA Suite. Most of the sessions are run by users who share their real world experience with the technology. And me and other PMs will also be running a few sessions and hands-on labs there. Check out the list of sessions in the Fusion Middleware track. And don't miss the Sunday symposium too.

• How can we make agile enjoyable for developers that like to personally, independently own large chunks from start to finish

  - by Kris

  We’re roughly midway through our transition from waterfall to agile using scrum; we’ve changed from large teams in technology/discipline silos to smaller cross-functional teams. As expected, the change to agile doesn’t suit everyone. There are a handful of developers that are having a difficult time adjusting to agile. I really want to keep them engaged and challenged, and ultimately enjoying coming to work each day. These are smart, happy, motivated people that I respect on both a personal and a professional level. The basic issue is this: Some developers are primarily motivated by the joy of taking a piece of difficult work, thinking through a design, thinking through potential issues, then solving the problem piece by piece, with only minimal interaction with others, over an extended period of time. They generally complete work to a high level of quality and in a timely way; their work is maintainable and fits with the overall architecture. Transitioning to a cross-functional team that values interaction and shared responsibility for work, and delivery of working functionality within shorter intervals, the teams evolve such that the entire team knocks that difficult problem over. Many people find this to be a positive change; someone that loves to take a problem and own it independently from start to finish loses the opportunity for work like that. This is not an issue with people being open to change. Certainly we’ve seen a few people that don’t like change, but in the cases I’m concerned about, the individuals are good performers, genuinely open to change, they make an effort, they see how the rest of the team is changing and they want to fit in. It’s not a case of someone being difficult or obstructionist, or wanting to hoard the juiciest work. They just don’t find joy in work like they used to. I’m sure we can’t be the only place that hasn’t bumped up on this. How have others approached this? If you’re a developer that is motivated by personally owning a big chunk of work from end to end, and you’ve adjusted to a different way of working, what did it for you?

• How would I implement this application idea?

  - by Mike Wills

  I am a D&D gamer and a developer that has mostly worked with ASP.NET applications professionally. I have written some chat bots in Node.js and I have only played a little with PHP but wrote nothing serious. I have had inspiration to create a site that allows a person to keep track of characters (aka the character sheet). I am thinking of using this as a learning opportunity to learn noSQL and to write a full javascript front-end. I want this application to save the value as I change it. So if I edit the armor class, it is saved immediately instead of waiting until I hit the submit button. I think that will make it easier to use while gaming and not losing anything because I forgot to save the change. I have never done anything like this. How do you implement this style of application? Is there a tutorial or howto to get me on the right path? While I would really like to use ASP.NET but I don't have a Windows server to publish on (and I really can't afford to pay for a service). What language that runs on Linux would work well for this type of application? Note: I feel noSQL would work in this case because of the sheer number of tables required to create something like this in SQL.

• How can I track a bug that caused a crash and was reported via apport / whoopsie?

  - by nealmcb

  It used to be that when a program crashed, especially when a user was using a pre-release of Ubuntu, apport could be used to open a bug report. The user could then track the bug, see if it affected others, help fix it, etc. As of Precise 12.04, this behavior and workflow changed. As I discovered in Bug #993450 “Apport fails to submit bug report”, by default apport no longer opens a bug report (and it is awkward but not impossible to get it to do so). At the same time people are noticing a new "whoopsie" process, as described at What is the 'whoopsie' process and what does it do?. After some more googling, I dug this blueprint up, which describes the whole process: ErrorTracker - Ubuntu Wiki. (It didn't mention whoopsie or daisy, so I added them - please correct me if I got it wrong). Wow - this sounds like great work to streamline and improve the crash reporting process. I'm left with this question: how does a user learn what the status of the problem is? The blueprint now has this requirement The user should have some way to check back on the status of their crash report; e.g. have some report ID they can look at to see statistics and/or any associated bug #. E.g. provide a serial number at time of filing that they can load via a web page later on. which seems unimplemented. Is there anything available in the meantime? And how does a developer get into the game? Going to https://daisy.ubuntu.com just provides an "Incorrect Content-Type" error message. Finally, I suggest documenting the apport behavior changes in the Release Notes. It should be of interest to anyone who has been trying to help out Ubuntu.

• Upgrading Visual Studio 2010

  - by Martin Hinshelwood

  I have been running Visual Studio 2010 as my main development studio on my development computer since the RC was released. I need to upgrade that to the RTM, but first I need to remove it. Microsoft have done a lot of work to make this easy, and it works. Its as easy as uninstalling from the control panel. I have had may previous versions of Visual Studio 2010 on this same computer with no need to rebuild to remove all the bits. Figure: Run the uninstall from the control panel to remove Visual Studio 2010 RC Figure: The uninstall removes everything for you.  Figure: A green tick means the everything went OK. If you get a red cross, try installing the RTM anyway and it should warn you with what was not uninstalled properly and you can remove it manually.   Once you have VS2010 RC uninstalled installing should be a breeze. The install for 2010 is much faster than 2008. Which could take all day, and then some on slower computers. This takes around 20 minutes even on my small laptop. I always do a full install as although I have to do c# I sometimes get to use a proper programming language VB.NET. Seriously, there is nothing worse than trying to open a project and the other developer has used something you don't have. Its not their fault. Its yours! Save yourself the angst and install Fully, its only 5.9GB. Figure: I always select all of the options.   Now go forth and develop! Preferably in VB.NET…   Technorati Tags: Visual Studio,VS2010,VS 2010

• How to connect to internet using huawei E303C datacard

  - by Rahul Choudhary

  It is very difficult to use ubuntu. After six hours of research on various websites and ubuntu blogs I was unable to connect to internet using my Huawei DataCard E303C. I wonder that if it takes so much long time to figure out how to connect to internet using a 3g datacard (Huawei E303C) to connect to internet, then how would I do my daily computing tasks using ubuntu. Is there anyone who can help me with that. My personal practical experiences says that using ubuntu instead of windows is not different but tough. Yes it is very tough to use ubuntu. Why it cannot be like we double click and software gets installed as it happens in windows and why we always have to use terminal to install everything. Why everything in ubuntu is very difficult and tough to accomplish. I am drifting away from ubuntu. Can any developer at ubuntu help keep my interest in ubuntu? Is there anyone who can lure me to use ubuntu again?

  Are you tired of the same old wallpaper on your Ubuntu desktop? Now you can go from blah to literally spacious, real-time styled views of Earth with the xplanetFX Wallpaper App for Linux. You can conveniently access the “file type” downloads, screenshots, and jump-to links all on the front page. For our example we downloaded the .deb setup file on our system. The setup file will need to download three additional files to complete the setup process. After those are downloaded all dependencies will have been met and you can complete the installation process. Once that is done you can find xplanetFX by going to the Accessories Section of your Ubuntu Menu. This is what the main control window looks like when you start xplanetFX for the first time. You should take a few moments to look through the various tabs and tweak the settings for items like location, screen resolution, timing, auto-start, etc. When you are done click on Execute and within a few moments your desktop will have a fresh new look!

• Researching runtime technologies (Xmas fun with HTML5)

  - by Eric Nelson

  The Internet Explorer 9.0 team just posted about Pirates love Daises. This is a showcase game for the power of HTML 5 running inside IE 9.0 – and the author has done a fantastic job (you can get more details from Grant’s blog post). A game developer is an ISV (Independent Software Vendor) – a B2C  ISV. In my role I don’t (typically) work with B2C ISVs, hence a reasonable question is “Why blog about it?”. I think applications like this demonstrate the power of HTML 5 and IE9 for delivering really rich user experiences which have the promise of working cross browser and cross platform - in the future as HTML5 capable browsers become the norm. Microsoft is investing heavily in implementing a great “run time” in IE9 if cross platform is an important requirement for your UX. And the other reason for blogging this… it is nearly Xmas and we all should be having a little more fun on the run in. Hence you can play with confidence that your defence to your manager is “I’m just researching a powerful runtime that Microsoft is working on which could be significant to our future B2B product directions” Play now (Needs HTML 5 browser such as IE9) Related Links: To install IE9 Beta or the Preview (which won’t replace your existing IE) check our the IE9 TestDrive center. Learn about our other important UX runtime with the on-demand recordings of the Silverlight FireStarter event.

• Open source clone for Starcraft

  - by sinekonata

  Two questions about a SC:Broodwar clone. Is there one yet? How likely is legal pursuit? Since almost all games I usually play now have an FOS alternative from alpha to way polished, I was wondering why can't I find one for SC, one of the biggest titans of the gaming community? So my first question is, is there a game that was made with the intention to emulate SC? Is it that I didn't look well enough? Could it really be that no one tackled what seems like a small effort compared to the creation of a game engine like Spring or games like Rigs of Rod or Minetest? And since SC is not being maintained at all shouldn't the incentive to see a bug free modable balanced version huge? What am I not getting here? In the event that there is none, is it a legal problem? Could it be that people expect Blizzard to release sources themselves? Or that developers don't see the point in having SC mechanics without the patented lore and aesthetics? And the trickier question, if I were to make SC an open source game, a total clone of it for the purposes of maintenance, modability, etc. Would Blizzard really sue a team of developer fans that just do them a favour knowing they don't lose any money from Korea broadcasts? Or would they do it not to set precedents. So thanks for reading all that, hope I'm not the only one to think it's weird that no one talks about it. See you.

• How do I mashup Google Maps with geolocated photos from one or more social networks?

  - by PureCognition

  I'm working on a proof of concept for a project, and I need to pin random photos to a Google Map. These photos can come from another social network, but need to be non-porn. I've done some research so far, Google's Image Search API is deprecated. So, one has to use the Custom Search API. A lot of the images aren't photos, and I'm not sure how well it handles geolocation yet. Twitter seems a little more well suited, except for the fact that people can post pictures of pretty much anything. I was also going to look into the API's for other networks such as Flickr, Picasa, Pinterest and Instagram. I know there are some aggregate services out there that might have done some of this mash-up work for me as well. If there is anyone out there that has a handle on social APIs and where I should look for this type of solution, I would really appreciate the help. Also, in cases where server-side implementation matters, I'm a .NET developer by experience.

• Issue 55 - Skin Object Tokens, Optimized Control Panel, OWS Validation and Security, RAD

  April 2010 Welcome to Issue 55 of DNN Creative Magazine In this issue we focus on the new Skin Object token method introduced in DotNetNuke 5 for adding tokens into a DotNetNuke skin. A Skin Object Token is a web user control which covers skin elements such as the logo, menu, search, login links, date, copyright, languages, links, banners, privacy, terms of use, etc. Following this we demonstrate how to install and use two Advanced DotNetNuke Admin Control Panels which are available for free from Oliver Hine. These control panels provide an optimized version of the admin control panel to improve performance and page load times, as well as a ribbon bar control panel which adds additional features. Next, we continue the Open Web Studio tutorials, this month we demonstrate some very advanced techniques for building a car parts application in Open Web Studio. Throughout the tutorial we cover form input, validation, how to use dependant drop down lists, populating checkbox lists and introduce a new concept of data level security. Data level security allows you to control which data a user can access within a module.

• Thinktecture IdentityServer v1.0

  - by Your DisplayName here!

  Yeah – it is finally done. I just uploaded the v1 bits to Codeplex and the documentation to our server. Here’s the official blurb… Thinktecture IdentityServer is an open source security token service based on Microsoft .NET, ASP.NET MVC, WCF and WIF. High level features Multiple protocols support (WS-Trust, WS-Federation, OAuth2, WRAP, JSNotify, HTTP GET) Multiple token support (SAML 1.1/2.0, SWT) Out of the box integration with ASP.NET membership, roles and profile Support for username/password and client certificates authentication Support for WS-Federation metadata Support for WS-Trust identity delegation Extensibility points to customize configuration and user management handling Disclaimer I did thorough testing of all features of IdentityServer - but keep in mind that this is an open source project and I am the only architect, developer and tester on the team. IdentityServer also lacks many of the enterprise-level features like configuration services, proxy support, operations integration etc. I only recommend using IdentityServer if you also understand how it works (to be able to support it). I am offering consulting to help you with customization and lock down - contact me. Download. Documentation. Up next is v1 of the Azure version. Have fun!

• Low hanging fruit where "a sufficiently smart compiler" is needed to get us back to Moore's Law?

  - by jamie

  Paul Graham argues that: It would be great if a startup could give us something of the old Moore's Law back, by writing software that could make a large number of CPUs look to the developer like one very fast CPU. ... The most ambitious is to try to do it automatically: to write a compiler that will parallelize our code for us. There's a name for this compiler, the sufficiently smart compiler, and it is a byword for impossibility. But is it really impossible? Can someone provide a concrete example where a paralellizing compiler would solve a pain point? Web-apps don't appear to be a problem: just run a bunch of Node processes. Real-time raytracing isn't a problem: the programmers are writing multi-threaded, SIMD assembly language quite happily (indeed, some might complain if we make it easier!). The holy grail is to be able to accelerate any program, be it MySQL, Garage Band, or Quicken. I'm looking for a middle ground: is there a real-world problem that you have experienced where a "smart-enough" compiler would have provided a real benefit, i.e that someone would pay for?

• What is the best practice for when to check if something needs to be done?

  - by changokun

  Let's say I have a function that does x. I pass it a variable, and if the variable is not null, it does some action. And I have an array of variables and I'm going to run this function on each one. Inside the function, it seems like a good practice is to check if the argument is null before proceeding. A null argument is not an error, it just causes an early return. I could loop through the array and pass each value to the function, and the function will work great. Is there any value to checking if the var is null and only calling the function if it is not null during the loop? This doubles up on the checking for null, but: Is there any gained value? Is there any gain on not calling a function? Any readability gain on the loop in the parent code? For the sake of my question, let's assume that checking for null will always be the case. I can see how checking for some object property might change over time, which makes the first check a bad idea. Pseudo code example: for(thing in array) { x(thing) } Versus: for(thing in array) { if(thing not null) x(thing) } If there are language-specific concerns, I'm a web developer working in PHP and JavaScript.

• Ubuntu security with services running from /opt

  - by thejartender

  It took me a while to understand what's going on here (I think), but can someone explain to me if there are security risks with regards to my logic of what's going on here as I am trying to set up a home web server as a developer with some good Linux knowledge? Ubuntu is not like other systems, as it has restricted the root user account. You can not log in as root or su to root. This was a problem for me as I have had to install numerous applications and services to /opt as per user documentation (XAMPPfor Linux is a good example). The problem here is that this directory is owned by root:root. I notice that my admin user account does not belong to root group through the following command: groups username so my understanding is that even though the files and services that I place in /opt belong to root, executing them by means of sudo (as required) does not mean that they are run as root? I imagine that the sudo command is hidden somewhere under belonging to the root user and has a 775 permission? So the question I have is if running a service like Tomcat, Apcahe, etc exposes my system like on other systems? Obviously I need to secure these in configurations, but isn't the golden rule to never run something as root? What happens if I have multiple services running under same user/group with regards to a compromised server?

• Quoting people for website dev. work

  - by Jason

  Hi All, I have recently given some quotes to a few people. And I need some advice about how things should be done... Q1: I've seen, heard of and read about a lot of developers using free resource sites online to obtain free Privacy Policy, Disclaimers etc for their/customers websites. A customer I quoted the other day expected me to write/get a disclaimer for their site. Who in their right mind would expect a document like that from a Web Developer? I just told them that they need to sort that stuff out themselves with a Lawyer or something, and then to send it to me so I can paste it on a webpage for them. Q2: If you're charging per hour, and you estimate that the project would take 1week to finish (including testing/releasing), but you soon realise that you'll require more time, do you RE-quote them? Or do you just finish off the site at the original quote price? Q3: How do you figure out how much you will charge your customers? Do you charge per-feature, or per hour, or per day, or all of the above? Thanks :)

• Design for XML mapping scenarios between two different systems [on hold]

  - by deepak_prn

  Mapping XML fields between two systems is a mundane routine in integration scenarios. I am trying to make the design documents look better and provide clear understanding to the developers especially when we do not use XSLT or any other IDE such as jDeveloper or eclipse plugins. I want it to be a high level design but at the same time talk in developer's language. So that there is no requirements that slip under the crack. For example, one of the scenarios goes: the store cashier sells an item, the transaction data is sent to Data management system. Now, I am writing a functional design for the scenario which deals with mapping XML fields between our system and the data management system. Question : I was wondering if some one had to deal with mapping XML fields between two systems? (without XSLT being involved) and if you used a table to represent the fields mapping (example is below) or any other visualization tool which does not break the bank ? I am trying to find out if there is a better way to represent XML mapping in your design documents. The widely accepted and used method seems to be using a simple table such as in the picture to illustrate the mapping. I am wondering if there are alternate ways/ tools to represent such as in Altova:

• Simple Multiplayer CCG System

  - by TobiHeidi

  I am working on a cross plattform Multiplayer CCG (web, android, ios). Here are my goals in design: I want to game to be easly accessible and understandable for non CCG players within the first minute of play. a single game should be played by 2 - 4 players a once, without problems if one players drops out during play. players should make their next turn simultaneous (without waiting for other to make their turns) My current approach: each Card has a point value for four Elements. In each Turn an Element is (randomly) selected and every Player chooses 1 card out of 3. The Player choosen the card with the highest value for that element wins the Round. After 10 Rounds the players a ranked by how many rounds they won. Why does this approach seems not optimal? It seems really to easy to determin the next best turn. Your own turn is to little affected by the play style of the others. I would love the have a system where some cards are better against other cards. A bit of rock paper scissors where you have to think about what next turn the other players will make or so. But really think freely. I would love to hear ideas may it be additions or new systems to make a CCG with roughly the stated design goals. Thanks

• Ubuntu installation on iMac

  - by Shanew

  I have an iMac configured as follows - Screen 27" CPU 3.4 GHz i7 Graphics AMD Radeon HD 6970 1024 MB I downloaded Ubuntu version 11.10 64 bit ISO and burnt that to both DVD and USB stick as per the instructions on Ubuntu's download page. Neither will boot. Symptoms are as follows - DVD: When the iMac is restarted and booted from DVD (labelled Windows which isn't mentioned in Ubuntu's website instructions) one line is displayed against a black screen displaying a message about the developer and date. After 5 minutes the message hangs and the DVD ceases to spin. USB Stick: Strangely I have to select the EFI boot CD icon which appears after holding down the Alt key. A text menu appears offering me to try Ubuntu without installing. I select this and the screen goes blank and stays blank. Any ideas? Lastly, after writing Ubuntu to DVD and USB stick, neither could be read by OSX making the instructions to eject them as per Ubuntu website's instructions useless. This might help? Thanks, Shane.

• Which shopping cart / ecommerce platform to choose?

  - by fabien7474

  I need to build an ecommerce website within a tight budget and schedule. Of course, I have never done that before, so I have googled out what my solutions are and I have concluded that the following were not valid candidates anymore : Magento : Steep learning curve osCommerce : old, bad design, buggy and not user-friendly Zencart, CRE Loaded, CubeCart : based on osCommerce Virtuemart, uberCart, eCart : based on CMS (Joomal, Drupal, WordPress) that is not necessary for my use-case So I finally narrowed down my choices to these solutions : PrestaShop : easy-to-use, great templating engine (smarty) but many modules are not free buy yet indispensable OpenCart : security issues and not a great support from the main developer. See here and here. So, as you can see, I am a little bit confused and if you can help me choosing an easy-to-use, lightweight and cheap (not-necessarily free) ecommerce solution, I would really appreciate. By the way, I am a Java/Grails programmer but I am also familiar with PHP and .NET. (not with Python or Ruby/Rails) EDIT: It seems that this question is more appropriate for the Webmaster StackExchange site. So please move this question to where it belongs (I cannot do that) instead of downvoting it. BTW, I have found out a question quite similar on SO (http://stackoverflow.com/questions/3315638/php-ecommerce-system-which-one-is-easiest-to-modify) which is quite popular.
