  • Is this form of cloaking likely to be penalised?

    - by Flo
    I'm looking to create a website which is considerably javascript heavy, built with backbone.js and most content being passed as JSON and loaded via backbone. I just needed some advice or opinions on likely hood of my website being penalised using the method of serving plain HTML (text, images, everything) to search engine bots and an js front-end version to normal users. This is my basic plan for my site: I plan on having the first request to any page being html which will only give about 1/4 of the page and there after load the last 3/4 with backbone js. Therefore non javascript users get a 'bit' of the experience. Once that new user has visited and detected to have js will have a cookie saved on their machine and requests from there after will be AJAX only. Example If (AJAX || HasJSCookie) { // Pass JSON } Search Engine server content: That entire experience of loading via AJAX will be stripped if a google bot for example is detected, the same content will be servered but all html. I thought about just allowing search engines to index the first 1/4 of content but as I'm considered about inner links and picking up every bit of content I thought it would be better to give search engines the entire content. I plan to do this by just detected a list of user agents and knowing if it's a bot or not. If (Bot) { //server plain html } In addition I plan to make clean URLs for the entire website despite full AJAX, therefore providing AJAX content to www.example.com/#/page and normal html to www.example.com/page is kind of our of the question. Would rather avoid the practice of using # when there are technology such as HTML 5 push state is around. So my question is really just asking the opinion of the masses on if it's likely that my website will be penalised? And do you suggest an alternative which avoids 'noscript' method

  • Designing configuration for subobjects

    - by Stefano Borini
    I have the following situation: I have a class (let's call it Main) encapsulating a complex process. This class in turn orchestrates a sequence of subalgorithms (AlgoA, AlgoB), each one represented by an individual class. To configure Main, I have a configuration stored into a configuration object MainConfig. This object contains all the config information for AlgoA and AlgoB with their specific parameters. AlgoA has no interest to the information relative to the configuration of AlgoB, so technically I could have (and in practice I have) a contained MainConfig.AlgoAConfig and MainConfig.AlgoBConfig instances, and initialize as AlgoA(MainConfig.AlgoAConfig) and AlgoB(MainConfig.AlgoBConfig). The problem is that there is some common configuration data. One example is the printLevel. I currently have MainConfig.printLevel. I need to propagate this information to both AlgoA and AlgoB, because they have to know how much to print. MainConfig also needs to know how much to print. So the solutions available are I pass the MainConfig to AlgoA and AlgoB. This way, AlgoA has technically access to the whole configuration (even that of AlgoB) and is less self-contained I copy the MainConfig.printLevel into AlgoAConfig and AlgoBConfig, so I basically have three printLevel information repeated. I create a third configuration class PrintingConfig. I have an instance variable MainConfig.printingConfig, and then pass to AlgoA both MainConfig.AlgoAConfig and MainConfig.printingConfig. Have you ever found this situation? How did you solve it ? Which one is stylistically clearer to a new reader of the code ?

  • Managing user privileges, best practices [on hold]

    - by Loïc N.
    I'm am new to web development. I'm creating a website where different user can have different privileges, such as creating/editing/deleting a news, or adding/editing/deleting whatever kind of content on the website. I started by creating a "user type" that would indicate the user's privileges (such as "user", "newser", "moderator", "admin", and so on), but I quickly started noticing issues that made me think that this might be a naive approach to this issue. What if I want to give a regular user the right to edit a news (for whatever reason)? Then the user would be half "user", half "newser". But the system I use can only handle one user-type. So what would be the best practice here? I was thinking of removing the concept of roles (or "user-types" such as newser) and only have the concept of "privilege", where every user could have zero to many privileges. So, to re-use the above example, if I wanted a user to have the right to edit some news, I would only have to give him a "edit news" privilege. Is this the way to go?

  • Executing Components in an Entity Component System

    - by John
    Ok so I am just starting to grasp the whole ECS paradigm right now and I need clarification on a few things. For the record, I am trying to develop a game using C++ and OpenGL and I'm relatively new to game programming. First of all, lets say I have an Entity class which may have several components such as a MeshRenderer,Collider etc. From what I have read, I understand that each "system" carries out a specific task such as calculating physics and rendering and may use more that one component if needed. So for example, I would have a MeshRendererSystem act on all entities with a MeshRenderer component. Looking at Unity, I see that each Gameobject has, by default, got components such as a renderer, camera, collider and rigidbody etc. From what I understand, an entity should start out as an empty "container" and should be filled with components to create a certain type of game object. So what I dont understand is how the "system" works in an entity component system. http://docs.unity3d.com/ScriptReference/GameObject.html So I have a GameObject(The Entity) class like class GameObject { public: GameObject(std::string objectName); ~GameObject(void); Component AddComponent(std::string name); Component AddComponent(Component componentType); }; So if I had a GameObject to model a warship and I wanted to add a MeshRenderer component, I would do the following: warship->AddComponent(new MeshRenderer()); In the MeshRenderers constructor, should I call on the MeshRendererSystem and "subscribe" the warship object to this system? In that case, the MeshRendererSystem should probably be a Singleton("shudder"). From looking at unity's GameObject, if each object potentially has a renderer or any of the components in the default GameObject class, then Unity would iterate over all objects available. To me, this seems kind of unnecessary since some objects might not need to be rendered for example. How, in practice, should these systems be implemented?

  • How to improve Algorithmic Programming Solving skill? [closed]

    - by gaurav
    Possible Duplicate: How can I improve my problem-solving ability? How do you improve your problem solving skills? Should I learn design patterns or algorithms to improve my logical thinking skills? What to do when you're faced with a problem that you can't solve quickly? Are there non-programming related activities akin to solving programming problems? I am a computer engineering graduate. I have studied programming since three years. I am good in coding and programming. I have been trying to compete in algorithmic competitions on sites such as topcoder,spoj since one and a half year, but I am still unable to solve problems other than too easy problems. I have learned from people that it takes practice to solve such problems. I try to solve those problems but sometimes I am unable to understand and even if I do understand I am unable to think of a good algorithm for solving it. Even if I solve I get Wrong answer and I am unable to figure out what is the problem with my code as it works on samples given on the sites but fails on test cases which they do not provide. I really want to solve those problems and become good in algorithms. I have read books for learning algorithms like Introduction to algorithms by CLRS,practicing programming questions. I have gone through some questions but they don't answer this question. I have seen the questions which are said duplicates but those questions focus on overall programming, but I am asking for algorithm related programming, basically for competing in programming which involve solving a problem statement then online judge will automatically evaluate it, such type of programming is quite different from the type of programming these questions discuss.

  • Tracking state of a one time event on a big website

    - by Mattis
    Assume a website with 250 million active users. I add a new feature to the website. Once a user visits I want to use a short tutorial to teach them how to use said feature. I only want them to complete the tutorial once (or actively click it away). What is the smart way to code the verification check for this? How do I track the progress in the database? Having a separate table with like NewTutorial_completed = 1 for user_id = 21312315 would just snowball. It also feels intuitively bad to check for every one-time event for every user on every page view. While writing the question I got one idea, to have a separate event log that is checked periodically for any new action the user need to see or perform. I push events to this log and once they are completed they are removed from the log. No need to store NewTutorial_completed = 1-type variables this way. I am sure this is a common problem. I would appreciate any input on what best practice is.

  • Math questions at a programmer interview?

    - by anon
    So I went to an interview at Samsung here in Dallas, Texas. The way the recruiter described the job, he didn't make it sound like it was too math-oriented. The job basically involved graphics programming and C++. Yes, math is implied in graphics programming, especially shaders, but I still wasn't expecting this... The whole interview lasted about an hour and a half and they asked me nothing but math-related questions. They didn't ask me a single programming question, which I found odd. About all they did was ask me how to write certain math routines as a C++ function, but that's about it. What about programming philosophy questions? Design patterns? Code-correctness? Constness? Exception safety? Thread safety? There are a zillion topics that they could have covered. But they didn't. The main concern I have is that they didn't ask any programming questions. This basically implies to me that any programmer who is good at math can get a job here, but they might put out terrible code. Of course, I think I bombed the interview because I haven't used any sort of linear algebra in about a year and I forget math easily if I haven't used it in practice for a while. Are any of my other fellow programmers out there this way? I'm a game programmer too, so this seems especially odd. The more I learn, the more old knowledge that gets "popped" out of my "stack" (memory). My question is: Does this interview seem suspicious? Is this a typical interview that large corporations have? During the interview they told me that Google's interview process is similar. They have multiple, consecutive interviews where the math problems get more advanced.

  • Where should I put bindings for dependency injection?

    - by Mike G
    I'm new to dependency injection and though I've really liked it so far, I'm not sure where bindings should go. I'm using Guice in Java, so some of what I say might be specific to just Guice. As I see it, there's two options: Accompanying the class(s) its needed for. Then, just write install(OtherClassModule.class) in whatever other modules want to be able to use said class. As I see it, the advantage of this is that classes that want to use it (or manage classes that want to use it) don't need to know any of the implementation detail. The issue I see is that what if two classes want to use two different versions of the same class? There's a lot of customization possible because of DI and this seems to restrict it a lot. Implemented in the module of the class(s) its needed for. It's the flip of what I said above. Now you have customization, but not encapsulation. Is there a third option? Am I misunderstanding something obvious? What's the best practice?

  • Using json as database with EF, how can I link EF and the json file during DbContext initialization?

    - by blacai
    For a personal testing-project I am considering to create a SPA with the following technologies: ASP.NET MVC + EF + WebAPI + AngularJS. The project will make use of small amount of data, so I was thinking I could use just a .json file as storage. But I am not sure about how to proceed with the link between EF and the json file in the initialization of the DbContext. I found a stackoverflow related question: http://stackoverflow.com/questions/13899342/can-we-use-json-as-a-database I know the basics of edit files and store data inside. What I tried is to get the data from the json file in the initilizer method and create the objects one by one. This is more a doubt about how this works if I save/update an object in the dbcontext, do I need to go through all the elements and add/update it manually? Is it better to rewrite the complete file? According to this http://stackoverflow.com/questions/7895335/append-data-to-a-json-file-with-php it is not a good practice to use json/XML for data wich will be manipulated. Anyone has experience with anything similar? Is this a really bad idea and I should use another kind of data-storage?

  • Should one generally develop a client library for REST services to help prevent API breakages?

    - by BestPractices
    We have a project where UI code will be developed by the same team but in a different language (Python/Django) from the services layer (REST/Java). The code for each layer exits in different code repositories and which can follow different release cycles. I'm trying to come up with a process that will prevent/reduce breaking changes in the services layer from the perspective of the UI layer. I've thought to write integration tests at the UI layer level that we'll run whenever we build the UI or the services layer (we're using Jenkins as our CI tool to build the code which is in two Git repos) and if there are failures then something in the services layer broke and the commit is not accepted. Would it also be a good idea (is it a best practice?) to have the developer of the services layer create and maintain a client library for the REST service that exists in the UI layer that they will update whenever there is a breaking change in their Service API? Conceivably, we would then have the advantage of a statically-typed API that the UI code builds against. If the client library API changes, then the UI code won't compile (so we'll know sooner that there was a breaking change). I'd also still run the integration tests upon building the UI or services layer to further validate that the integration between UI and the service(s) still works.

  • Why do some bad websites rank well?

    - by BradB
    Consider the following scenario: you are pitching SEO/Website Optimisation to a prospective client and you explain to them the importance of great copy and content, how acquiring links (ethically) can increase page rank, why the quality of the HTML build matters (H1, H2 tags, w3c validation etc), why keyword research is beneficial, you may drop in a few Google Webmaster Guideline or Matt Cutts references to back up your claims and rubbish the "back hat" approach as being no longer effective for good measure. Your advice is ethical and in the eyes of best practices, spot on. Then, the client points out to you some of their long established competitors on Google and you see these competitor websites ranking in the top spots (1 to 3) for medium to highly competitive search phrases that your client wants to compete for. These websites totally contradict your ethical approach and pretty much violate every best practice previously noted. They even out perform other "white hat" competitors who are in accordance with the above guidelines. I experienced this today. One of these well ranking websites had: About six microsites with more or less the same copy and a slightly varied layout Little or not textual content I would almost say duplicate content across the sites, but there was so little of it it could barely qualify for being duplicate All the content in Flash (with a music track that kicked in on each page load, not so much of an SEO issue - but it helps paint the picture) Keyword stuffing behind the Flash file with a bunch of black text on black background in the style of keyword 1 keyword 2,keyword1,keyword 2,keyword 2 keyword 3 and so on... The exact keyword stuffed combination present on every page of the website A bunch of clearly self made links from poor quality forums and directories with little or no Page Rank Links exchanged across the microsites How do you explain your way out of this when this hard evidence is sat in front of you undermining your great pitch?

  • How do I convince my team that a requirements specification is unnecessary if we adopt user-stories?

    - by Nupul
    We are planning to adopt user-stories to capture stakeholder 'intent' in a lightweight fashion rather than a heavy SRS (software requirements specifications). However, it seems that though they understand the value of stories, there is still a desire to 'convert' the stories into an SRS-like language with all the attributes, priorities, input, outputs, source, destination etc. User-stories 'eliminate' the need for a formal SRS like artifact to begin with so what's the point in having an SRS? How should I convince my team (who are all very qualified CS folks by the way - both by education and practice) that the SRS would be 'eliminated' if we adopted user-stories for capturing the functional requirements of the system? (NFRs etc can be captured too, but that's not the intent of the question). So here's my 'work-flow' argument: Capture initial requirements as user-stories and later elaborate them to use-cases (which are required to be documented at a low level i.e. describing interactions with the UI prototypes/mockups and are a deliverable post deployment). Thus going from user-stories to use-cases rather than user-stories to SRS to use-cases. How are you all currently capturing user-stories at your workplace (if at all) and how do you suggest I 'make a case' for absence of SRS in presence of user-stories?

  • Are you ready for SharePoint 2010?

    - by Michael Van Cleave
    With SharePoint's next release on the horizon (May 12th) many of my clients and colleagues are starting to ramp up for the upcoming tidal wave of functionality. Microsoft has been doing a terrific job of getting as much information out in the public lime light as possible over the last few months and I think that will definitely pay off with regards to acceptance of the new version of SharePoint. However, there are still some aspects of the new platform that are a little murky. Aspects such as: "Should we upgrade?" "Will my current installation upgrade without issues?" "What benefits will I see by upgrading?" "What are the best practices for upgrading or best practice in general relating to 2010?" "How should we plan to deploy SharePoint 2010 in our organization?" There is a ton of information out there, but how do you go about getting some of these questions answered? Well, I am glad you asked. (J) ShareSquared will be delivering a FREE SharePoint 2010 Readiness Webinar that will cover Preparation, Strategies, and Best Practices for the upcoming version of SharePoint. The webinar will be presented by 2 of ShareSquared's outstanding SharePoint MVP's; Gary Lapointe and Paul Stork. As all those T.V. commercials say… "Space is limited, so sign up now!" Just kidding, well kind of but not really. I am sure that the signup will be huge and space is really limited so the sooner you sign up the better. I would hate for any of you to miss out. If you have any questions please don't hesitate to shoot me a e-mail through my blog or contact ShareSquared directly. See you at the webinar! Michael

  • Design of input files reading when it comes to defaults/transformations

    - by Stefano Borini
    Suppose you have an application that reads an input file, on a language that does not support the concept of None. The input is read, parsed, and the contents are stored on a structure for later use. Now, in general you want to keep into account transformation of the data from the input, such as adding default values when not specified, or adding full path information to relative path specified in the input. There are two different strategies to achieve this. The first strategy is to perform these transformations at input file reading time. In practice, you put all the intelligence into the input parser, and your application has no logic to deal with unexpected circumstances, such as an unspecified value. You lose the information of what was specified and what wasn't, but you gain in black-boxing the details. Your "running code" needs that information in any case and in a proper form, and is not concerned if it's the default or a user-specified information. The second strategy is to have the file reader a real one-to-one mapper from the file to a memory-stored object, with no intelligent behavior. unspecified values are not filled (which may however be a problem in languages not supporting None) and data is stored verbatim from the file. The intelligence for recovery must now go into the "running code", which must check what was specified in the file, eventually fall back to a default, or modify the input properly before using it. I would like to know your opinion on these two approaches, and in particular which one you found the most frequently implemented.

  • .Net search engine architecture and technology choice

    - by shrivb
    I am in the process of designing a search engine for an asp.net site. The site currently uses Microsoft Indexing Server to index and search content which range from simple text files to MS documents to PDFs. MIS is also used to crawl File servers. MIS in tandem with Index Server Companion crawls for content from external sites. I intend to replace MIS with the indexer/crawler I am trying to build. Since my platform is completely on the Microsoft stack, I cant afford to have a Java application server. Thus, Solr, and effectively, SolrNet is ruled out. With this being the context, I have couple of questions. 1.Technology choice I had done my initial investigation and looked at Lucene.Net. There seemed to be 2 issues in using Lucene.Net. First being, it cant crawl external content. There doesn't seem to be a direct port of Nutch in .Net. Second, since it is just an indexer, it cant parse various document types. The parsing is left to the developer. So, what would be best technology choice on the .Net platform to achieve indexing & crawling? Are there any .Net open source libraries available for document parsing? 2.Architectural pattern Is there any general architectural pattern or best practice that needs to be followed in designing such a search engine? Thanks in advance.

  • Validating allowed characters or validating disallowed characters

    - by Tom
    I've always validated my user input based on a list of valid/allowed characters, rather than a list of invalid/disallowed characters (or simply no validation). It's just a habit I picked up, probably on this site and I've never really questioned it until now. It makes sense if you wish to, say, validate a phone number, or validate an area code, however recently I've realised I'm also validating input such as Bio Text fields, User Comments, etc. for which the input has no solid syntax. The main advantage has always seemed to be: Validating allowed chars reduces the risk of you missing a potentially malicious character, but increases the risk the of you not allowing a character which the user may want to use. The former is more important. But, providing I am correctly preventing SQL Injection (with prepared statements) and also escaping output, is there any need for this extra barrier of protection? It seems to me as if I am just allowing practically every character on the keyboard, and am forgetting to allow some common characters. Is there an accepted practice for this situation? Or am I missing something obvious? Thanks.

  • DI and hypothetical readonly setters in C#

    - by Luis Ferrao
    Sometimes I would like to declare a property like this: public string Name { get; readonly set; } I am wondering if anyone sees a reason why such a syntax shouldn't exist. I believe that because it is a subset of "get; private set;", it could only make code more robust. My feeling is that such setters would be extremely DI friendly, but of course I'm more interested in hearing your opinions than my own, so what do you think? I am aware of 'public readonly' fields, but those are not interface friendly so I don't even consider them. That said, I don't mind if you bring them up into the discussion Edit I realize reading the comments that perhaps my idea is a little confusing. The ultimate purpose of this new syntax would be to have an automatic property syntax that specifies that the backing private field should be readonly. Basically declaring a property using my hypothetical syntax public string Name { get; readonly set; } would be interpreted by C# as: private readonly string name; public string Name { get { return this.name; } } And the reason I say this would be DI friendly is because when we rely heavily on constructor injection, I believe it is good practice to declare our constructor injected fields as readonly.

  • Hallmarks of a Professional PHP Programmer

    - by Scotty C.
    I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the hallmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/

  • Choosing between PHP and Java

    - by user996459
    I've recently started University, studying Computing and IT. My Uni focuses on Java. My study will consist of mathematics, 'boring' IT related stuff and several Java units such as: -Software development with Java, -Object-oriented Java programming, -Relational databases: theory and practice (using Java), -Developing concurrent distributed systems (using Java), -Software engineering with objects (using Java). I'm trying to determine whenever I should focus on Java and self study it in my free time so that I can actually learn and become a competent Java programmer by the time I graduate, or, only do enough Java to get the degree but in my free time self study PHP and related web technologies. Job market in my area appears to be balanced for the two, salary and availability wise. Regardless of which patch I'd take getting a job should not be a problem however Java does seem to pay almost insignificantly more. In terms of my interest and career expectations, I don't have anything specific planned. I very much enjoy writing code but I don't really care what kind. So far I equally enjoyed writing C, AutoIT, vb.net, PHP and even Java. Basically, I'm happy as long as I get to type in code (be it low level programming or web back-end scripting). So the question really is, would my Uni and their Java focus profit me should I choose PHP? Or should I buy what my university is selling and stick to Java like a fly sticks to poop...? Apologies for cryptic writing, still learning English

  • A Year of Upheaval for Procurement Professionals-New Report & Webinar

    - by DanAshton
    2013 will see significant changes in priorities and initiatives among procurement professionals as they balance the needs of their enterprises with efforts to add capabilities for long-term procurement success. In response, procurement managers will expand their organization’s spend influence via supplier relationship management, sourcing, and category management. These findings are part of the new report, “2013 Procurement Key Issues: Going Deeper and Broader to Deliver Borderless Procurement Services,” by the Hackett Group. The authors say that compared to similar studies over the last five years, 2013 is registering the greatest year-over-year changes in priorities for both procurement performance and capability issues. Three Important PrioritiesThe survey found that procurement professionals are focusing their attention in three key areas. Cost reduction. Controlling expenses is always a high priority, but with 90 percent of the respondents now placing this at the top of their performance concerns, the Hackett analysts say this “clearly shows that, for better or worse, cost reduction is king” in 2013. Technology innovation. Innovation has shot up significantly in the priority rankings and is now tied with spend influence for second among procurement professionals. Sixty-five percent of the survey participants said pursuing game-changing innovation and technology is a top procurement initiative. Managing supply risk. This area registered a sharp rise in importance because of its role in protecting profits, Hackett says. Supplier compliance with performance milestones and regulatory requirements is receiving particular attention, with an emphasis on efficient management of cross-functional workflows. “These processes create headaches for suppliers and buyers alike, and can detract from strategic value creation when participants are bogged down in processing paper and spreadsheets,” the report explains.  For more insights into the current state of the procurement industry, download the full report, “2013 Procurement Key Issues: Going Deeper and Broader to Deliver Borderless Procurement Services” and watch a Webcast featuring Global Procurement Advisory Practice Leader for The Hackett Group, Chis Sawchuk, and Managing Supervisor of Supply Chain Processes and Systems for Ameren, Chris Nelms.
