  • SO-overflow induced passivity - how to cope?

    - by Ruben
    After not really working on my pet project for a while, I discovered Stackoverflow and upon perusing it more intensely I was quite amazed. I'm a bit of a perfectionist, so when I found eye-openers here highlighting many of the mistakes I made, I first wanted to fix everything. However, it's a pet project for a reason: I'm self-taught and I'm studying psychology, so programming skills can never become priority one (though it often helps, even in this field). Issues that stuck out were numerous security issues (e.g. CSRF-prevention and bcrypt eluded me) not object-oriented (at least the PHP part, the JS-part mostly is) no PHP framework used, so many of my DIY takes on commonly-tackled components (auth, ...) are either bad or inefficient really poor MySQL usage (no prepared statements, mysql extension, heard about setting proper indices two days ago) using mootools even though JQuery seems to be fashionable, so there's more probably always going to be better integration with services I'd like to use (like google visualization) So, my SO-induced frenzy turned into passivity. I can't do it all (soon) in the rather small amount of spare time I can spend on working on my project. I can leave some of the issues be in good conscience (speed stuff: an unfinished & unpublished project will never become popular, right?). No clear conscience without good security though and if I don't use a framework for auth and other complex stuff I'll regret having to do it myself. One obvious answer would probably be going open-source, but I think the project would need to become more impressive before others would commit to it. I can't afford to employ someone either. I do think the project deserves being worked on, though. How should I tackle it anyway? What's the best practice for little-practice people?

  • Amazon how does their remarkable search work?

    - by JonH
    We are working on a fairly large CRM system /knowledge management system in asp.net. The db is SQL server and is growing in size based on all the various relationships. Upper management keeps asking us to implement search much like amazon does. Right from there search you can specify to search certain objects like outdoor equipment, clothing, etc. and you can even select all. I keep mentioning to upper management that we need to define the various fields to search on. Their response is all fields...they probably look at the search and assume that it is so simple. I'm the guy who has to say hold on guys we are talking about amazon here. My question is how can amazon run a search on an "all" category. Also one of the things management here likes is the dynamic filters. For instance, searching robot brings up filters specific to a robot toy. How can I put management in check and at least come up with search functionality that works like amazon. We are using asp.net, SQL server 2008 and jquery.

  • Microsoft MVP Award &ndash; Data Platform Development

    - by Dane Morgridge
    For those who don't already know, yesterday I received my first Microsoft MVP Award in Data Platform Development.  With less than 5,000 MVPs in the world overall and about 20 in the Data Platform category, saying I am honored would be an understatement.  From the first time I spoke at a code camp, I was totally hooked and have had a blast travelling around the east coast speaking at code camps and users groups.  I'd like to take the time to thank Dani Diaz (@danidiaz) for the nomination and everyone who supported me, especially my wife Lisa for letting me travel and speak as much as I have and putting up with me for late nights and such.  Roska Digital, my employer, also deserves a shout out for supporting me and giving me the necessary time off to get to speaking engagements.  With any luck, the next year will be at least as fun if not more than the last one has.  I hope to see you at a code camp or user group meeting soon! I would also like to send a congratulations to the other new Philly Area MVPs: John Angelini (@johnangelini) & Ned Ames (@nedames) You can find out more about the Microsoft MVP Award at https://mvp.support.microsoft.com/

  • Types of quotes for an HTML templating language

    - by Ralph
    I'm developing a templating language, and now I'm trying to decide on what I should do with quotes. I'm thinking about having 3 different types of quotes which are all handled differently: backtick ` double quote " single quote ' expand variables ? yes no escape sequences no yes ? escape html no yes yes Backticks Backticks are meant to be used for outputting JavaScript or unescaped HTML. It's often handy to be able to pass variables into JS, but it could also cause issues with things being treated as variables that shouldn't. My variables are PHP-style ($var) so I'm thinking that might mess with jQuery pretty bad... but if I disable variable expansion w/ backticks then, I'm not sure how would insert a variable into a JS code block? Single Quotes Not sure if escape sequences like \n should be treated as literals or converted. I find it pretty rare that I want to disable escape sequences, but if you do, you could use backticks. So I'm leaning towards "yes" for this one, but that would be contrary to how PHP does it. Double Quotes Pretty certain I want everything enabled for this one. Modifiers I'm also thinking about adding modifiers like @ or r in front of the string that would change some of these options to enable a few more combinations. I would need 9 different quotes or 3 quotes and 2 modifiers to get every combination wouldn't I? My language also supports "filters" which can be applied against any "term" (number, variable, string) so you could always write something like "blah blah $var blah"|expandvars Or "my string"|escapehtml Thoughts? What would you prefer? What would be least confusing/most intuitive?

  • ASP.NET MVC 2 Hosting :: MVC2 deploy - Could not load file or assembly 'System.Web.MVC, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

    - by mbridge
    A new MVC 2 project worked on my local machine but when it was deployed to the test server it gave the error 'Could not load file or assembly 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.' I have the full Visual Studio 2010 installed on my local machine but just the .NET 4 framework installed on the test servers. It seems the MVC assemblies do not come with .NET 4 framework itself so how to make MVC 2 work on the test servers? When I installed Visual Studio 2010 on my local machine it came with all the fruit included (.NET4 framework, MVC2 etc) so the System.Web.Mvc.dll can be found in my machine's GAC (C:\Windows\assembly). However, since there is no need to bloat the web servers only the plain old .NET4 framework has been installed on the test servers. This does NOT include the MVC assembly and that is why it cannot be found by the web application. You need this assembly to be on your web servers that you are deploying to but you want to avoid having to copy them into the GAC manually and doing all that gacutil mess or maybe you don't have access to your servers if they are hosted by provider. Solution You need to make the System.Web.Mvc assembly bin deployable... okay that doesn't sound easy but here is how to do it for the necessary MVC references: Simply right click the reference and select 'Properties' Then change 'Copy Local' to 'True': Note If your server has .NET 3.5 sp1 installed the new(ish) assemblies System.Web.Routing and System.Web.Abstractions will already be in the GAC. If you had previously deployed an MVC 1 application to a .NET 3.5 server you may remember having to deploy the other two assemblies too. Since MVC2 requires at least .NET 3.5 sp1 you will not need to worry about these assemblies, just System.Web.Mvc

  • Idea of an algorithm to detect a website's navigation structure?

    - by Uwe Keim
    Currently I am in the process of developing an importer of any existing, arbitrary (static) HTML website into the upcoming release of our CMS. While the downloading the files is solved successfully, I'm pulling my hair off when it comes to detect a site structure (pages and subpages) purely from the HTML files, without the user specifying additional hints. Basically I want to get a tree like: + Root page 1 + Child page 1 + Child page 2 + Child child page1 + Child page 3 + Root page 2 + Child page 4 + Root page 3 + ... I.e. I want to be able to detect the menu structure from the links inside the pages. This has not to be 100% accurate, but at least I want to achieve more than just a flat list. I thought of looking at multiple pages to see similar areas and identify these as menu areas and parse the links there, but after all I'm not that satisfied with this idea. My question: Can you imagine any algorithm when it comes to detecting such a structure? Update 1: What I'm looking for is not a web spider, but an algorithm do create a logical tree of the relationship of the pages to be able to create pages and subpages inside my CMS when importing them. Update 2: As of Robert's suggestion I'll solve this by starting at the root page, and then simply parse links as you go and treat every link inside a page simply as a child page. Probably I'll recurse not in a deep-first manner but rather in a breadth-first manner to get a more balanced navigation structure.

  • Programming Practice/Test Contest?

    - by Emmanuel
    My situation: I'm on a programming team, and this year, we want to weed out the weak link by making a competition to get the best coder from our group of candidates. Focus is on IEEExtreme-like contests. What I've done: I've been trying already for 2 weeks to get a practice or test site, like UVa or codechef. The plan after I find one: Send them (the candidates) a list of direct links to the problems (making them the "contest's problem list) get them to email me their correct answers' code at the time the judge says they have solved it and accept the fastest one into the team. Issues: We had practiced on UVa already (on programming challenges too), so our former teammate (which will be in the candidate group) already has an advantage if we used it. Codechef has all it's answers public, and since it shows the latest ones it will be extremely hard to verify if the answer was copied. And I've found other sites, like SPOJ, but they share at least some problems with codechef, making them inherit the issue of Codechef So, what alternatives do you think there are? Any site that may work? Any place to get all stuff to set up a Mooshak or similar contest (as in the stuff to get the problems, instructions to set up the server itself are easy to google)? Any other idea?

  • Part 3: Customization Strategy or how long does it take

    - by volker.eckardt(at)oracle.com
    The previous part in this blog should have made us aware, that many procedures are required to manage all these steps. To review your status let me ask you a question:What is your Customization Strategy?Your answer might be something like, 'customization strategy, well, we have standards and we let requirement documents approve'.Let me ask you another question:How long does it take to redeploy all your customizations into a fresh installation?In 90% of all installations the answer to this question would be: we can't!Although no one would have to do it (hopefully), just thinking about it and recognizing that we have today too many manual steps involved, different procedures and sometimes (undocumented) manual steps to complete a customization installation. And ... in general too many customizations.Why is working with customizations often so complicated and time consuming?Here are the key reasons as I have identified them in my projects:Customization standards defined, but not maintainedDifferent knowledge on developer side (results getting an individual developer touch)No need to automate deployment (not forced by client)Different documentation styles, not easy to hand over to someone elseDifferent development concepts, difficult for the maintenanceJust the minimum present for testing, often positive testing onlyDeviations from naming conventions accepted, although definedComplicated procedures, therefore sometimes partially ignoredAnd last but not least, hand made version control (still)If you would have to 'redeploy all your customizations' you would have to Follow all your own standards and best practiceTrack deviations and define corrective tasksAutomate as much as possible, minimize manual tasksDo not allow any change coming in without version controlUtilize products to support you in deploymentMinimize hand made scripts and extensive documentationReview regularly used techniques to guarantee that all are in line with the current release and also easy maintainableCreate solution libraries and force the team to contribute and reuseDefine quality activities and execute themDefine a procedure to release customizationsI know, it is easy to write down, but much harder to manage. Will provide some guidelines in my next blog.Volker

  • How to Search for (and Find) Solaris Docs

    - by rickramsey
    Just the other day, I went to the recently-released Oracle Solaris 11 library to search for information about the print service changes. I knew there had been changes in Oracle Solaris 11, but could not remember the new approach to printing. So, being the optimist that I (never) am, I went to the Oracle Solaris 11 Information Library on docs.oracle.com and typed "print service" into the search box. Imagine my surprise when the response back was: We did not find any search results for: print service site:download.oracle.com url:/docs/cd/E23824_01. OMG! WTF? Are you kidding me? After throwing a few stuffed animals at my computer screen, I tried again. Is search broken? Well, sort of (and I'm trying to get it fixed). In the meantime, however, there is a reasonably simple user workaround. Possibly unnoticed by most people, there is a Within drop-down menu on the Oracle search results page. If you simply open the Within menu, select Documentation, and click the little magnifying glass again, you (should) get the expected results. Is it perfect? No, but at least it's an improvement over being completely broken. - Janice Critchlow, Information Architect, Systems Website Newsletter Facebook Twitter

  • How to get tilemap transparency color working with TiledLib's Demo implementation?

    - by Adam LaBranche
    So the problem I'm having is that when using Nick Gravelyn's tiledlib pipeline for reading and drawing tmx maps in XNA, the transparency color I set in Tiled's editor will work in the editor, but when I draw it the color that's supposed to become transparent still draws. The closest things to a solution that I've found are - 1) Change my sprite batch's BlendState to NonPremultiplied (found this in a buried Tweet). 2) Get the pixels that are supposed to be transparent at some point then Set them all to transparent. Solution 1 didn't work for me, and solution 2 seems hacky and not a very good way to approach this particular problem, especially since it looks like the custom pipeline processor reads in the transparent color and sets it to the color key for transparency according to the code, just something is going wrong somewhere. At least that's what it looks like the code is doing. TileSetContent.cs if (imageNode.Attributes["trans"] != null) { string color = imageNode.Attributes["trans"].Value; string r = color.Substring(0, 2); string g = color.Substring(2, 2); string b = color.Substring(4, 2); this.ColorKey = new Color((byte)Convert.ToInt32(r, 16), (byte)Convert.ToInt32(g, 16), (byte)Convert.ToInt32(b, 16)); } ... TiledHelpers.cs // build the asset as an external reference OpaqueDataDictionary data = new OpaqueDataDictionary(); data.Add("GenerateMipMaps", false); data.Add("ResizetoPowerOfTwo", false); data.Add("TextureFormat", TextureProcessorOutputFormat.Color); data.Add("ColorKeyEnabled", tileSet.ColorKey.HasValue); data.Add("ColorKeyColor", tileSet.ColorKey.HasValue ? tileSet.ColorKey.Value : Microsoft.Xna.Framework.Color.Magenta); tileSet.Texture = context.BuildAsset<Texture2DContent, Texture2DContent>( new ExternalReference<Texture2DContent>(path), null, data, null, asset); ... I can share more code as well if it helps to understand my problem. Thank you.

  • Since a few days, Dropbox stopped syncing

    - by Fabio
    Theres a new problem with nautilus-dropbox and is the worst for a service like Dropbox: stopped syncing and their tech support don't believe their users. The problem is: start dropbox it downloads index creates folders start to download files stop downloading files or the speed is like 0.3k/seg even deleting everything doesn't work, even syncing a single folder with a few files, not even configuring a different limit speed or let all your bandwith, nothing works for me and i have found many users with the same problem. it's strange, i have two computers with ubuntu 14.04 and one with windows 7, and in one of the linux machines it works fine, but not in the other one. Both of them are x64. The answers from the tech support starts with "delete everything and reinstall" to "you may be blocking port 443", yeah, sure (and if i do that half of internet dissapears, idiot), but nothing works. Someone has some idea? i cant find any log file (at least a text log file like in /var/log) to understand what is dropbox doing and what is not working. PS: sorry for my "english", is not my language Examples: dropbox slow on ubuntu 14.04 Dropbox does not sync on ubuntu 14.04 Dropbox Status (in spanish but is the same thing) fabio@canopus:~$ dropbox status Sincronizando (Quedan 330 archivos., Faltan 9 días.)

  • #mvvmlight V4 update for Win8 RTM

    - by Laurent Bugnion
    With Windows 8 RTM out of the doors (at least for some of us), it was also time to create an update to MVVM Light. I selected the V4 RTM to do this (V4.0.23).This RTM version was released a few weeks ago with no much bells and whistles because I was just too busy to write much about it. Now after some vacation, I will resume blogging on all my favorite topics including of course MVVM Light. Upgrade Upgrading the installations should not require an ununistall, so try to simply run the MSI downloaded from the Download section at http://mvvmlight.codeplex.com/. Should you encounter any issue, try to uninstall the old version first following the steps at http://galasoft.ch/mvvm/cleaning/. Upgrading current apps from Win8 RP to Win8 RTM I didn’t recompile the assemblies of MVVM Light, so if you had a version running with V4.0.23 on Windows 8 RP, you should be able to use the same DLLs on Windows 8 RTM. If you were using earlier versions however, I would recommend doing an upgrade. I noticed a warning regarding the signing certificate. It is due to the PFX key which appears to be outdated after the upgrade to Windows 8 RTM. I solved this warning by replacing the old PFX key with a new one I copied from a new project. The warning did not cause the build to fail though. About MVVM Light V4 RTM The RTM is finalizing quite a lot of issues. The change log is available at http://galasoft.ch/mvvm/installing/changes/. There are some issues that are either still open or that popped up since then, and I am working on V4.1 to be released in the next few weeks. In addition to that, I have plans to support Windows Phone 8 (when it comes) and have a nice list of ideas for V5 with a few new components. Thanks again for your continuous support of MVVM Light!

  • Reliable alert dialogs from the shell

    - by intuited
    I'd like to have a message pop up in response to various system events, mostly in order to be able to set reminders for myself from a shell session. There are a few ways to do this; zenity seems to be the most polished. However, I've found at least two problems with zenity: Messages do not appear on all workspaces. I tried using the gtk option --screen to control this, but they just appear on the current workspace regardless. So if I am switching workspaces as the message comes up, I will not see it. Messages do not appear above all other windows. Specifically, if I am using guake, a new zenity message will appear below the guake window and I won't be able to see it. I tried a few other apps a while back. Both gmessage and xmessage exhibited problem 1; gmessage also exhibited problem 2. I did find that kalarm, which can be scripted from the command line, worked acceptably, but I'm trying to avoid running the KDE stack if possible, and would prefer something lightweight with zenity's versatility. It seems that it might be possible to arrange for these problems to be resolved by setting the WM_CLASS, but I'm in a bit over my head there. It might also be possible to make modifications to the window after it launches with a script, but again I'm not sure where to look for resources on that.

  • How to solve Bumblebee/Nvidia Optimus issues with kernel 3.4 (works perfectly under 3.2)

    - by theJimy
    I installed Ubuntu and could setup to utilize my Intel HD 3000/Geforce GT 540M hybrid graphics perfectly with the method described here: How well do laptops with Nvidia Optimus work? Everything works fine under Kernel 3.2. Now I wanted to upgrade though to Kernel 3.4, as it brings many improvements, especially in saving battery life (ie. Intel RC6)... at least from what I heard. While I had no issues installing the 3.4 Kernel under Ubuntu 12.04 and everything so far runs fine, Bumblebee causes issues under kernel 3.4. When trying to run commands like optirun, lsmod (or similar kernel tools) these just lock up and never return. The Bumblebee developers seem to refuse to help with mainline kernels (as seen here: https://github.com/Bumblebee-Project/bbswitch/issues/17 ). Does anyone know, how to solve this issue? Could I solve this probably, by compiling the kernel and/or Bumblebee against the kernels sources myself and having a Ubuntu-like kernel? Any other idea that might help me to solve this myself, so I could profit from the 3.4 features and Optimus, would be very appreciated.

  • How to handle people who lie on their resume [closed]

    - by Juliet
    Moderator comment Please note that this is a two year old question that has just been migrated from Stack Overflow. Please take your time to read all the answers and ask yourself "would my answer add anything to this?". I'm conducting technical interviews to fill a few .NET positions. Many of the people I interview really do know .NET pretty well, but I find at least 90% embellish their skillset anywhere between "a little" to "quite drastically". Sometimes they fabricate skills relevant to the position they're applying for, sometimes they don't. Most of the people I interview, even the most egregious liars, are not scam artists. They just want to stand out among the crowd, so they drop a few buzzwords on their resume like "JBoss", "LINQ", "web services", "Django" or whatever just to pad their skillset and stay competitive. (You might wonder if a person that lies about those skills is just bluffing their way through a technical interview. My interviews involve a lot of hands-on coding and problem-solving – people who attempt to bluff will bomb the hands-on coding portion in the first 3 minutes.) These are two open-ended questions, but it would really help me out when I make my recommendations to the hiring managers: Regarding interviewing etiquette, should I attempt to determine whether a person really possesses all of the skills they claim to have? Can I do this without making the candidate feel uncomfortable? Regarding the final decision, should I recommend candidates who are genuinely qualified for the positions they're applying for, even if they've fabricated portions of their skillset?

  • How Do I Print Photos?

    - by Takkat
    Other than for Windows in Ubuntu there are no fancy utilities provided from printer manufacturers to print photos. I am aware of Gnome Photo Printer and of Photoprint, the first being easy to handle, the latter having more options. However I wonder if there are any other or maybe even better alternatives (including plugins) to perform the following tasks: Print photos in the best photo-resolution the driver offers Adjust paper size for standard values of photo papers Choose paper tray if the printer has more than one Print out multiple photos on one page including mixed sizes (grids) Multiple prints with same settings Borderless printing if the printer is capable of this Any additional options like pre-processing for color correction or noise reduction would be nice to have but are not so essential. Update According to this spec it seems not to so easy to accomplish the simple task of printing photos. Indeed all applications I have gone through have major drawbacks that make printing photos almost impossible. Below I will list what put me off using them for photo printing: Gnome Photo Printer: no thumbnails, no grids Photoprint: does not keep settings, GUI broken, no standard photo size, no thumbs Eye Of Gnome: no multiple pages, no grids Gimp + Images Grid Layout: far too many steps to finally find that prints are always different to their previews. F-Spot: no grids Picasa 3: no grids, very few fixed paper sizes, 300 dpi only flPhoto: strange GUI, no thumbs, no printer settings, did not print at all Windows: Ooops - everything works fine! But I want Ubuntu to do this! After half a pack of ink cartridges and half a pack of photo paper cards I am getting tired of testing. At least Gimp and Picasa looked promising but both don't keep their promise when it comes to printing. I'd already be happy to quickly print a few photos with EOG if bug #80220 was fixed - but it's still on "wishlist".

  • What is the value in hiding the details through abstractions? Isn't there value in transparency?

    - by user606723
    Background I am not a big fan of abstraction. I will admit that one can benefit from adaptability, portability and re-usability of interfaces etc. There is real benefit there, and I don't wish to question that, so let's ignore it. There is the other major "benefit" of abstraction, which is to hide implementation logic and details from users of this abstraction. The argument is that you don't need to know the details, and that one should concentrate on their own logic at this point. Makes sense in theory. However, whenever I've been maintaining large enterprise applications, I always need to know more details. It becomes a huge hassle digging deeper and deeper into the abstraction at every turn just to find out exactly what something does; i.e. having to do "open declaration" about 12 times before finding the stored procedure used. This 'hide the details' mentality seems to just get in the way. I'm always wishing for more transparent interfaces and less abstraction. I can read high level source code and know what it does, but I'll never know how it does it, when how it does it, is what I really need to know. What's going on here? Has every system I've ever worked on just been badly designed (from this perspective at least)? My philosophy When I develop software, I feel like I try to follow a philosophy I feel is closely related to the ArchLinux philosophy: Arch Linux retains the inherent complexities of a GNU/Linux system, while keeping them well organized and transparent. Arch Linux developers and users believe that trying to hide the complexities of a system actually results in an even more complex system, and is therefore to be avoided. And therefore, I never try to hide complexity of my software behind abstraction layers. I try to abuse abstraction, not become a slave to it. Question at heart Is there real value in hiding the details? Aren't we sacrificing transparency? Isn't this transparency valuable?

  • Teaching myself, as a physicist, to become a better programmer

    - by user787267
    I've always liked physics, and I've always liked coding, so when I got the offer for a PhD position doing numerical physics (details are not relevant, it's mostly parallel programming for a cluster) at a university, it was a no-brainer for me. However, as most physicists, I'm self taught. I don't have broad background knowledge about how to code in an object oriented way, or the name of that specific algorithm that optimizes the search in some kD tree. Since all my work so far has been more concerned about the physics and the scientific results, I undoubtedly have some bad habits - more so because my coding is my own, and not really teamwork. I have mostly used C since it is very straightforward and "what you write is what you get" - no need for fancy abstractions. However, I have recently switched to C++ since I'd like to learn more about the power that comes with abstraction, and it's pretty C-like (syntax-wise at least). How do I teach myself to code in a good, abstract way like a graduate in computer science? I know my code is efficient, but I want it to be elegant as well, and readable. Keep in mind that I don't have time to read several 1000-page tomes about abstract programming. I need to spend time on actual, physics related research (my supervisor would laugh at me if he knew I spent time thinking about how to program elegantly). How do I assess if my work is also good from a programmer's perspective?

  • How to search for a tester?

    - by MainMa
    As a freelance developer, a few times I tried to find some testers to be able to let them test my software/web applications. If I try to find them, it's because most of the customers are not intended to hire external testers and don't see why this can benefit to them, so products are UI-untested and buggy. I tried lots of things. Discussion boards for IT people, specific websites for people who search for a job. Every time I clearly precise that I'm looking for product testers. I completely failed to find anybody for this job. I found instead two types of people: Non IT people who try to qualify as testers, but don't have enough skills for that, and don't really know what testing is and how to do it, Programmers, who are skilled as programmers, but not as testers, and who mostly don't understand neither what testing is about (or think it's the same thing as code review, or it consists in writing unit tests). Of course, they submit general programmers resumes, where they describe their high experience in Assembler and C++, but don't tell anything about anything related to the job of a tester. What I'm doing wrong? Isn't it called "tester"? Is there at least a tester job, different from general programming job? Is there any precise requirement to require from each candidate which can eliminate non IT people and general programmers?

  • Trying to learn how to use WCF services in a WPF app, using MVVM

    - by Rod
    We're working on a major re-write of a legacy VB6 app, into a WPF app. I've written several WCF services, which are meant to be used with the new WPF app. We want to use the MVVM design pattern to do this, but we don't have experience at that. So, in order to learn MVVM we've watched a video on WindowsClient called How Do I: Build Data-driven WPF Application using the MVVM pattern. This is a great introduction, and we refer to it a lot, but for our situation it doesn't quite give us enough. For example, we're not certain how to use datasets returned by my WCF services in our new WPF app using the ideas that Todd Miranda introduced in the video I referenced. If we did as we think we're supposed to do, then we should design a class that is exactly like the class of data returned in my WCF service. But we're wondering, why do that, when the WCF service already has such a class? And yet, the class in the WPF app has to at least implement the INotifyPropertyChanged interface. So, we're not sure what to do.

  • Role of systems in entity systems architecture

    - by bio595
    I've been reading a lot about entity components and systems and have thought that the idea of an entity just being an ID is quite interesting. However I don't know how this completely works with the components aspect or the systems aspect. A component is just a data object managed by some relevant system. A collision system uses some BoundsComponent together with a spatial data structure to determine if collisions have happened. All good so far, but what if multiple systems need access to the same component? Where should the data live? An input system could modify an entities BoundsComponent, but the physics system(s) need access to the same component as does some rendering system. Also, how are entities constructed? One of the advantages I've read so much about is flexibility in entity construction. Are systems intrinsically tied to a component? If I want to introduce some new component, do I also have to introduce a new system or modify an existing one? Another thing that I've read often is that the 'type' of an entity is inferred by what components it has. If my entity is just an id how can I know that my robot entity needs to be moved or rendered and thus modified by some system? Sorry for the long post (or at least it seems so from my phone screen)!

  • Is my first employer expecting too much?

    - by priyank patel
    This is my first job as a programmer. I am working using the followig technologies: ASP.NET C# HTML CSS Javascript JQuery I work for a firm which develops software for small banking firms. Currently they have their software running in 100 firms. Their software is developed in Visual Fox Pro. I was hired to develop an online version of this software. I am the only developer. My boss is another developer, the only other developer in the firm. Therefore, my employer has a total of two developers. My boss does not have any experience with .NET development. I have been working on this project for 8 months. The progress is there, but has been very slow. I try my best to do what my boss asks. But the project just seems too ambitious for me. The company has not done have any planning for the project. They just ask me to develop what their older software provides. So I have to deal with front end, back end, review code, design architecture, and more. I have decided to give my best. I try a lot. But the project sometimes just seems to be overwhelming. Question: Is it normal for a beginner programmer to be in this place? Are my employers just expecting too much of a new programmer? As a programmer, am I lacking skills one needs to deal with this? I always feel the need to work in at least a small team, if not big one. I am just not able judge my condition. Also I am paid very low salary. I do work on Saturday as well. Please, help to clarify my judgment. Any suggestions are welcome.

  • Who would be the most efficacious Patron Saint of Programmers? [closed]

    - by Peter Turner
    The purpose of this question is to find someone out there to intercede for us and help our coding (not to magically align the bytes), to inspire our daily grind of software development by their lives of heroic virtue, to unite us under a common patron and to keep us on the straight and narrow path (i.e. don't be evil). In days of yore, the professional guilds had a patron saint. Regardless of whether we have a higher tendency to be atheists or not, who would you choose as the patron saint of programmers and what would be your criteria? Some people have chosen St. Isidore of Seville, but he's more like the patron saint of Wikipedia. If you're not Catholic please don't hesitate to nominate someone, just say what your criteria is. At the very least they should be dead and have lived a life of heroic virtue - or have died trying. It's a very pragmatic and noble custom which I heartily encourage. But if you find the practice off-putting, please don't be offended. I only mean to ask this question to other like minded programmers, which I have reason to believe exist. If you add a picture and a maybe make up a prayer that'd be excellent. It doesn't have to be gilded, illuminated and rhyme, although that would be sweet.

  • Podcast Show Notes: Architect Day Panel Highlights

    - by Bob Rhubart
    The 2010 series of Oracle Technology Network Architect Day events kicked off in May with events in Dallas, Texas, Redwood Shores, California, and Anaheim, California. The centerpiece of each Architect Day event is a panel discussion that brings together the day's various presenters along with experts drawn from the local Oracle community. This week’s ArchBeat program presents highlights from the panel discussion from the event held in Anaheim. Listen The voices you’ll hear in these highlights belong to (listed in order of appearance): Ralf Dossmann: Director of SOA and Middleware in Oracle’s Enterprise Solutions Group LinkedIn | Oracle Mix Floyd Teter: Innowave Technology, Oracle ACE Director Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Basheer Khan: Innowave Technology, Oracle ACE Director Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Jeff Savit:  Oracle virtualization expert, former Sun Microsystems principal engineer Blog | LinkedIn | Oracle Mix Geri Born: Oracle security analyst LinkedIn | A 10-minute podcast can't really do justice to the hour-long panel discussion at each Architect Day event, let alone the discussion that is characteristic of each session throughout each Architect Day. But at least you’ll get a taste of what you’ll find at the live events. You’ll find slide decks and more from this first series of 2010 events in the Architect Day Artifacts post on this blog. More dates/cities will be added soon to the Architect Day schedule.  Coming Soon Next week’s ArchBeat program kicks off a three-part series featuring Cameron Purdy,  Oracle ACE Director Aleksander Seovic, and Oracle ACE John Stouffer in a conversation about data grid technology and Oracle Coherence.
