• Tool to check if XML is valid in my VS2012 comments

  - by davidjr

  I am writing the documentation for our companies software developed with vs2012. I need to add xml examples to the summary of each class, due to xml instantiation of objects. We are using sandcastle to create the documentation (company choice), and I want to be able to review my xml comments without building the help file every time. Is there an application that anyone would recommend where I can view how the xml renders before I build the help file? Here is my example: /// <summary> /// Performs DFT on a data array, writes output in a CSV file. /// </summary> /// <example> /// <para>XML declaration</para> /// <code lang="xml" xml:space="preserve"> /// %lt;DataProvider name="DftDP" description="Computes DFT" etc... I want to check the XML to make sure it is valid, maybe by copy and pasting it into a tool of some sort?

• How to practice object oriented programming?

  - by user1620696

  I've always programmed in procedural languages and currently I'm moving towards object orientation. The main problem I've faced is that I can't see a way to practice object orientation in an effective way. I'll explain my point. When I've learned PHP and C it was pretty easy to practice: it was just matter of choosing something and thinking about an algorithm for that thing. In PHP for example, it was matter os sitting down and thinking: "well, just to practice, let me build one application with an administration area where people can add products". This was pretty easy, it was matter of thinking of an algorithm to register some user, to login the user, and to add the products. Combining these with PHP features, it was a good way to practice. Now, in object orientation we have lots of additional things. It's not just a matter of thinking about an algorithm, but analysing requirements deeper, writing use cases, figuring out class diagrams, properties and methods, setting up dependency injection and lots of things. The main point is that in the way I've been learning object orientation it seems that a good design is crucial, while in procedural languages one vague idea was enough. I'm not saying that in procedural languages we can write good software without design, just that for sake of practicing it is feasible, while in object orientation it seems not feasible to go without a good design, even for practicing. This seems to be a problem, because if each time I'm going to practice I need to figure out tons of requirements, use cases and so on, it seems to become not a good way to become better at object orientation, because this requires me to have one whole idea for an app everytime I'm going to practice. Because of that, what's a good way to practice object orientation?

• Why does Komodo edit not open files on doubleclick due to some path encoding error?

  - by gakera

  When I double click a file in finder to open in Komodo edit, it displays an error message saying it can't find the file and the path is displayed, but with wrong encoding, such that special characters such as "ó" and "ð" are displayed as some weird boxes. Screenshot: http://i51.tinypic.com/2qkleg4.jpg I'm running OSX Snow Leopard 10.6.4 and Komodo Edit version 5: "Komodo Edit, version 5.2.4, build 4343, platform macosx-x86. Built on Tue Dec 8 18:18:35 2009." When I drag the file into Komodo edit it opens just fine displaying the path correctly with "ó"s and all :P This doesn't happen if I right click the file in finder and select to open it with TextEdit or Word or (God forbid) MacVim - only when I select to open it in Komodo edit. This is annoying as all hell.

• Memory concerns while plotting escape from DLL Hell in Delphi

  - by Peter Turner

  I work on a program with about 50 DLLs that are loaded from one executable, it's an old organically grown program where the only rationale for creating a new DLL is that one previously didn't exist to fill a given need. (and namespaces didn't exist in Delphi so it never crossed our mind to make dll1.main.pas, dll2.main.pas or something even more unique) What we want to do is consolidate all these DLLs into one executable, since none of them are used out of the program, there shouldn't be much of a problem. The concern my boss has is that if we did this, the memory overhead for terminal server clients would go through the roof. So, I've stepped through enough initialization code to know that lots of stuff is done every time a DLL is loaded in to memory, but say I've got a project with about 4000 files, and 50 dlls, 10 of which are probably utilized by any one user in any one session of the program. The 50 dlls are about 2/3rds form files, if not more, but beyond that there's not a lot of other resources being loaded (only a few embedded pictures, icons, cursors, etc..). If I loaded all these files in to memory, how much memory is used per unit? how much is used per class? How do I keep the overhead down? and what is the biggest project one can reasonably expect to build with Delphi? This tidbit won't help answering, but I think it might clarify what my boss is worried about, we currently start our program at about 18megs, normal working conditions are usually less than 40 megs, he thinks it could climb as high as 120 megs.

• PHP: A config file in .ini or .php format?

  - by Tim Visee

  I'm working on a huge CMS system, and I asked myself what configuration format I should use. There are two common formats for configuration files. The first one is an INI file, containg all the configuration properties. Then you can simply parse this INI file using build in PHP functions. A second option is to use a PHP file containing a regular PHP array with these configuration properties. Now, it's easier to edit an INI file, but a PHP file give's you more options, for example it allows you to add a function which retrieves one of the configuration options while reading the configuration file. Note: The PHP configuration file would only contain an array of configuration, no initialization functions or anything. (This is possible of course, but it's not implemented by default) Now, what is recommend for me to use as configuration file? What is the most common format for a configuration file? Should I go for simplicity with the INI files, or with a more dynamic one using PHP. One thing to note, this is not for personal usage. I'm planning to release the CMS system soon, and a lot of websites are scheduled already to change to my CMS system.

• Using LDAP Attributes to improve performance for large directories

  - by Vineet Bhatia

  We have a LDAP directory with more than 50,000 users in it. LDAP Vendor suggests maximum limit of 40,000 users per LDAP group. We have number of inactive users and those are being purged but what if we don't get below the 40,000 users? Would switching to using multivalued attribute at user record level instead of using LDAP groups yield better performance during authentication, adding new users, etc? I know most server software (portal, application servers, etc) use LDAP groups. But, we have a standardized web service interface for access control instead of relying on server software to map LDAP groups to security roles. Each application uses this common "access control web service". Security roles are used within application to build fine-grained ACL used within each enterprise application.

• Firefox or Chrome - how to force a specific encoding for a page

  - by Mike

  Hi, I am accessing an intranet site built by amateurs, that was constructed to be "best viewed by IE" (arghhh!). The site is in portuguese. All accented letters are jammed and do not appear as they should. As I create sites myself, I know that the best way to build a site in portuguese and other latin languages is to use the "charset=iso-8859-1" on the page's HTML encoding. This will ensure cross-browser and platforms compatibility. But I have no way to change this, because I am a visitor on this site. I don't know the encoding they are using. What I ask is: is there a way I can force my browser (Chrome or Firefox) to recode the page using the correct charset? I need this to work on Ubuntu.

• Virtual NIC on VM couldn't ping externally after Vmotion

  - by ToreTrygg

  Today I vmotioned 5 MS SQL 2005 servers over to a new DRS Cluster. All SQL servers use the "Production_LAN" network and a single virtual NIC of type "VMXNET 3". The first 4 SQL VM (Windows 2003 Standard or Enterprise x32 bit) vmotioned over without a hitch. The last SQL VM I vmotioned (Windows 2003 Standard x64 bit R2) vmotioned over without error, but I upon completion, I could no longer ping the VM. I went into the VM and could not even ping the gateway, however I could ping the loopback. This SQL server is extremely busy in comparison with the previous 4 VM's. I restarted the server and it came back up with the virtual nic working just fine. The build of both servers (vmotioner and vmotionee) is ESX 4.0.0 175625 - So, pre-update 1. Should I suspect the network switch/VM for possibly not updating the mac table on the switch? Anybody else ever have this issue or know what may have caused it? Thank you!

• My boss has a different idea of a website's UX [migrated]

  - by NicoJuicy

  Let me explain the situation. I started transforming a "old (.Net 2.0)" Application into a webapplication. Problem here is, that no-one here is really acquainted with the UX of a website (Simple, efficient). Eventhough, i still have to regard that the website can be tailored to a customer needs through parameters (yeah, i know :s ) For example: I wanted to have a layout similar to invoicemachine (= as simple as possible). -- He wants a Ribbon toolbar. Going to a supplier gives the list of supplier -- He wants to display the "Create Supplier" screen where you can use the wildcards in a certain textbox, to search for a specific Supplier and then give the list of the suppliers. Also, i need 4 search/filter mechanisms: people can search per field with wildmarks can filter the suppliers search a keyword through all the data of a supplier filter the "list Suppliers" page by the first letter of the name. LIST Suppliers | A | D | Z Adam Wrincle ADD |EDIT |Delete Damzel InDistress ADD |EDIT |Delete Zorro ADD |EDIT |Delete I can't seem to get through to him, that the UX of a website needs to be differently than a Windows Application. If he wants to bring all the logic of the windows app into a website, why letting me build a website then? Stick to the old solution. Am i mistaking so hard or how could i convince / show him that an online-solution is something different than the offline solution. He already "saw" online solutions of other applications to get an idea, but if i suggest something he won't listen (if it's GUI / UX related, that is).

• RAID5 on SmartArray P410i online resize

  - by datacompboy

  I have P410i+256M Cache without battery backup. My RAID5 was build over 3*136GB disks, now all disks were replaced to a 3*300GB array. How can I extend it to use the whole space? HPacucli doesn't allows that, I think this might be because no battery is present. I have a redundant power supply. All data is mirrored over DRBD to a secondary server, so I can try to resize with a chance of loss of data in case of power failure, but I prefer to have an online resize.

• Using standard e-mail address as user system wide name

  - by PeterMmm

  I'm going to re-build a very old Lotus Notes infrastructure coming from 4.x towards 8.5. I'm trying to setup Domino so that all user names should be of a single string or the internet e-mail address. For example the user "John Smith/ACME" should be in the whole system jsmith or [email protected] . I still get jsmith/ACME all around. Where it is most annoying is in the NAB when creating a new message. Is there a way to get all addresses in uniform standard e-mail adress format at least in mail ? The mixup in the destination like "John Smith/ACME, [email protected]" confused the users.

• How can story and gameplay be artfully merged?

  - by NauticalMile

  Let me give some context. Three of my friends and I have a pretty good game idea cooking. It's based off of a prototype I made that's evolving into a cool game mechanic. The mechanic itself is a toy that's fun on its own, but we haven't designed any puzzles around it yet. We have a design document going, and we are answering a lot of questions about what's in the game. It's become clear early on that everyone (including myself) likes the characters and the story a lot. Considering what our favorite games are, this is unsurprising. A story driven game makes sense to me. I like the emphasis that Paper Mario: The Thousand-Year-Door, Portal 2, and Tomb Raider place on story, and I imagine our game will have a similar feel (lots of dialogue, plot twists, lovable characters). However, one team member raised this point in the design doc: I am feeling like [fleshing out the story] is our biggest hurdle right now for making more design decisions - like more specific decisions about levels etc. Is this true? I am uncertain about working on the story extensively before gameplay, and my uneasiness was reinforced when I read this question about story vs. gameplay. What I want to say is: "Let's continue to work on the story, but also start brainstorming and prototyping abstract puzzles and combat sequences, and we'll creatively match them together later." Is this a reasonable approach? If so, how much of the development of these elements should be done independently? Should I try and create a whole bunch of puzzles while my other teammates focus on story and aesthetics? Then when we have a lot of story and game 'chunks' we can match them with eachother to build something meaningful. Or should we focus on iterating individual levels as distinct units where puzzles, story, etc... are designed together? Or maybe we need to put our excitement about the story on hold and just focus on gameplay. Is there another approach to design that we can take? Am I missing something crucial? I have discussed story and gameplay because they seem the most likely to be at odds with each other, but we also have to consider user interface, music, art direction, etc... Can we design these independently as well?

• DIY Carbonator Creates Pop Rocks Like Fizzy Fruit [Science]

  - by Jason Fitzpatrick

  If you’ve ever sat around wishing that scientists would stop wasting time trying to solve pressing global problems and instead genetically engineer a bizarre but delicious hybrid of Pop Rocks candy and wholesome fruit, this mad scientist experiment is for you. Over at Evil Mad Scientist Laboratories they share a really fun weekend project. Contributor Rich Faulhaber was looking for a way to make eating fruit extra fun and science-infused for his kids. His solution? Build a homemade carbon dioxide injector that infuses fruit with carbonation. Having trouble imagining that? Envision a bowl of strawberries where every strawberry burst into a crazy flurry of strawberry flavor and champagne bubbles every time you bit into it. Fizzy fruit! Hit up the link below to see how he took pretty common parts: a C02 tank from a paint ball gun, a water filter canister from the hardware store, and other cheap and readily available parts (with the exception of the gas regulator which he suggests you shop garage sales and surplus stores to find a deal on), and combined them together to create a C02 fruit infuser. Hit up the link below to read more about his setup and the procedure he uses to infuse fruit with carbonation.

• Web Sites All Start When Debugging a Web Site - Visual Studio 2010

  - by Daniel Lackey

  I wanted to blog about this because it was an annoyance to me and I couldn't figure out why for quite some time. Have you ever tried debugging one web application in your solution but when you do, all other web sites in your solution build and then start up their respective Visual Studio Development Server? It's not a major problem, but it adds time to waiting for what you are actually trying to debug to start up. After digging through Visual Studio 2010 settings, I finally found the option to turn it off. It is called Always Start When Debugging and is located in the Properties pane for the web project (click on the project .proj file in Visual Studio IDE). This is set to True by default each time you create a new Web Application project. Setting this to false will solve your problems. You will need to set this to false for all web applications in your solution as shown below: In addition, you can set properties on which port the development server uses each time it debugs. This is helpful if you want the port to stay the same for testing purposes. In contrast, you can set it to use a dynamic port each time so if you have a co-worker that is debugging it on a different session on the same server, you won't run into any problems with using the same port. The machine won't allow you to debug two sessions on the same port. Pretty basic stuff but it seemed like a really quirky setting to me.

• How can I install a headless JDK on an Ubuntu Jaunty server?

  - by Hanno Fietz

  I recently set up a build server that requires a JDK to run (for example, to compile the Java sources). The OpenJDK package in Ubuntu pulls in the OpenJDK JRE as a dependency which, in turn, depends on a large number of packages that are only relevant for graphical environments. For the standard JRE, there's a headless version of the package, but for the JDK, no. This issue has been discussed in various places before, and one solution that I found and used was this: $ apt-get --no-install-recommends -d install openjdk-6-jdk $ dpkg -i --ignore-depends=openjdk-6-jre /path/to/just-downloaded.deb While this worked, it now leaves my system with a broken dependency tree and apt-get refuses further installs untill I run apt-get -f. Is there a better solution to this?

• Business Strategy - Google Case Study

  Business strategy defined by SMBTN.com is a term used in business planning that implies a careful selection and application of resources to obtain a competitive advantage in anticipation of future events or trends. In more general terms business strategy is positioning a company so that it has the greatest competitive advantage over others in the markets and industries that they participate in. This process involves making corporate decisions regarding which markets to provide goods and services, pricing, acceptable quality levels, and how to interact with others in the marketplace. The primary objective of business strategy is to create and increase value for all of its shareholders and stakeholders through the creation of customer value. According to InformationWeek.com, Google has a distinctive technology advantage over its competitors like Microsoft, eBay, Amazon, Yahoo. Google utilizes custom high-performance systems which are cost efficient because they can scale to extreme workloads. This hardware allows for a huge cost advantage over its competitors. In addition, InformationWeek.com interviewed Stephen Arnold who stated that Google’s programmers are 50%-100% more productive compared to programmers working for their competitors.  He based this theory on Google’s competitors having to spend up to four times as much just to keep up. In addition to Google’s technological advantage, they also have developed a decentralized management schema where employees report directly to multiple managers and team project leaders. This allows for the responsibility of the technology department to be shared amongst multiple senior level engineers and removes the need for a singular department head to oversee the activities of the department.  This is a unique approach from the standard management style. Typically a department head like a CIO or CTO would oversee the department’s global initiatives and business functionality.  This would then be passed down and administered through middle management and implemented by programmers, business analyst, network administrators and Database administrators. It goes without saying that an IT professional’s responsibilities would be directed by Google’s technological advantage and management strategy.  Simply because they work within the department, and would have to design, develop, and support the high-performance systems and would have to report multiple managers and project leaders on a regular basis. Since Google was established and driven by new and immerging technology, all other departments would be directly impacted by the technology department.  In fact, they would have to cater to the technology department since it is a huge driving for in the success of Google.

• After 10 Years, MySQL Still the Right Choice for ScienceLogic's "Best Network Monitoring System on the Planet"

  - by Rebecca Hansen

  ScienceLogic has a pretty fantastic network monitoring appliance.  So good in fact that InfoWorld gave it their "2013 Best Network Monitoring System on the Planet" award.  Inside their "ultraflexible, ultrascalable, carrier-grade" enterprise appliance, ScienceLogic relies on MySQL and has since their start in 2003.  Check out some of the things they've been able to do with MySQL and their reasons for continuing to use MySQL in these highlights from our new MySQL ScienceLogic case study. Science Logic's larger customers use their appliance to monitor and manage  20,000+ devices, each of which generates a steady stream of data and a workload that is 85% write. On a large system, the MySQL database: Averages 8,000 queries every second or about 1 billion queries a day Can reach 175,000 tables and up to 20 million rows in a single table Is 2 terabytes on average and up to 6 terabytes "We told our customers they could add more and more devices. With MySQL, we haven't had any problems. When our customers have problems, we get calls. Not getting calls is a huge benefit." Matt Luebke, ScienceLogic Chief Software Architect.? ScienceLogic was approached by a number of Big Data / NoSQL vendors, but decided against using a NoSQL-only solution. Said Matt, "There are times when you really need SQL. NoSQL can't show me the top 10 users of CPU, or show me the bottom ten consumer of hard disk. That's why we weren't interested in changing and why we are very interested in MySQL 5.6. It's great that it can do relational and key-value using memcached." The ScienceLogic team is very cautious about putting only very stable technology into their product, and according to Matt, MySQL has been very stable: "We've been using MySQL for 10 years and we have never had any reliability problems. Ever." ScienceLogic now uses SSDs for their write-intensive appliance and that change alone has helped them achieve a 5x performance increase.

• How to move an UIView along a curved CGPath according to user dragging the view

  - by Felipe Cypriano

  I'm trying to build a interface that the user can move his finger around the screen an a list of images moves along a path. The idea is that the images center nevers leaves de path. Most of the things I found was about how to animate using CGPath and not about actually using the path as the track to a user movement. I need to objects to be tracked on the path even if the user isn't moving his fingers over the path. For example (image bellow), if the object is at the beginning of the path and the user touches anywhere on the screen and moves his fingers from left to right I need that the object moves from left to right but following the path, that is, going up as it goes to the right towards the path's end. This is the path I've draw, imagine that I'll have a view (any image) that the user can touch and drag it along the path, there's no need to move the finger exactly over the path. If the user move from left to right the image should move from left to right but going up if need following the path. This is how I'm creating the path: CGPoint endPointUp = CGPointMake(315, 124); CGPoint endPointDown = CGPointMake(0, 403); CGPoint controlPoint1 = CGPointMake(133, 187); CGPoint controlPoint2 = CGPointMake(174, 318); CGMutablePathRef path = CGPathCreateMutable(); CGPathMoveToPoint(path, NULL, endPointUp.x, endPointUp.y); CGPathAddCurveToPoint(path, NULL, controlPoint1.x, controlPoint1.y, controlPoint2.x, controlPoint2.y, endPointDown.x, endPointDown.y); Any idead how can I achieve this?

• Good Freelance models for web developers

  - by Matthew Underwood

  I am a web developer with four years of experience in PHP, MYSQL and experience in Javascript etc. One day I hope to develop a freelance career in web development. Areas of freelance that I am thinking of going towards includes Wordpress, Magento development along with bespoke applications. I am also thinking of doing some consultancy work for clients and businesses when I build up some more experience and technical knowledge. I want to offer a web development service to potential clients that plays on my strengths in what I know but most importantly has a market. Web development can cover so many subjects that its difficult to pick out the areas that have demand. I am also curious to find out if web developers offer services that bring in a monthly income e.g application maintenance or database maintenance? Is there a market for certain areas like WordPress plugins or bespoke applications? Are there certain things to avoid because of work duration, unrealistic client expectations or the fact that its impossible to find a market for it? As professional and experienced freelance web developers have you learned some important do's and don'ts? Is there certain services that the majority of web developers offer because its in high demand? This is the one area of web development freelancing that I cant get my head around. I know there is never a definitive answer but there must be some good practises and general consensus on this subject. Web designers design websites they offer a lump sum and get paid monthly sometimes to add new content, PPC and SEO consultants market sites to the top this will involve monthly payments, web development doesn’t seem so clear cut.

• Is this possible?

  - by PythonNewbie2

  Hello, I'm exploring some technologies and JSP with JSF 2.0 and Primefaces seems really cool. I'm new to all of these, but I'm a fast learner. I wondering if I can create the web app I want withh JSP/JSF/Primefaces or should I be looking to different technologies? If I should, which ones do you recommend? Here's a basic description of the app: Users log in with their username and password (maybe I can somehow incorporate google OPENID)? With a really nice UI, they will be presented a large list of questions specific to a certain category, for example, JSP. When they click on any of these questions, a little input opens up below it to allow the user to put in a link. If the link they enter has the same question on that webpage the URL points to, they will be awarded one point. This question then disappears and gets added to a different page that has a list of all correctly linked questions. On the right side of the screen, there will be a leaderboard with the usernames of the people with the top ten points. Is this possible with JSP/JSF/Primefaces, or should I be looking elsewhere for a different web technology? The idea is relatively simple - to be able to compile links to external websites for specific questions. I know I can build the UI easily with Primefaces. What I'm not sure is if JSP/JSF gives the ability to parse HTML at a certain URL to see if it contains words. I can do this with python easily by using urllib. Any help would be appreciated!!! What would be more helpful than a "Yes" or "No" answer would be links to where I can see sample code of external HTML parsing. Your input is truly appreciated! Thanks!

• XSP2 hangs after some time

  - by Sebi

  I'm running a REST/JSON webservice (SVC) using xsp2 (and xsp2 through Apache/mod_mono). After some hours, the service just hangs and outputs a timeout after about 5 minutes. This can only be solved by restarting xsp2. Sometimes multiple restarts are needed to get it running again. I've made a small sample webservice simply returning a "pong". The example is available in the bug report: https://bugzilla.novell.com/show_bug.cgi?id=608158 The bug can sometimes be reproduced following these steps: Steps to Reproduce: 1. start xsp2 (webservice) 2. request http://[server]/WSPing.svc/ping Actual Results: After some time, I always get timeouts. I'm running a gentoo linux as a XEN DomU and i'm using Visual Studio to build and publish the service. Any hints???
