  • Should a website be on a topic?

    - by Rana Prathap
    I run an online writers' community where authors publish their literature works and other members of the community read and comment on them. The authors write a wide variety of literature pieces(such as haikus, stories, poems, scientific articles, personal narratives) on a wide variety of topics(about sun and anything under it). My intention of providing the authors with search engine traffic is largely affected by the non existence of topical focus of the website(or so I think). Is there a way to overcome this problem?

  • Designing a completely new database/gui solution for my compnay

    - by user1277304
    I'm no expert when it come to everything Visual Studio 2010 and utilizing SQL server 2008. I'm sure some of my personal projects I've built for personal use would get laughed off the face of the planet, but SQLCe has been the solution I was looking for those home type of projects. And they work, flawlessly. Now I feel it's time to step up to the big league. I want to develop a complete, unified and module based solution for my company that I'm working for. We're still using stuff from the 80s for goodness sake! I use Excel and query the ancient database on my own because I can't stand the GUI. Nothing against people of age, but the IDE our programmers are using is from the stone age, and they use APL of all things with it. I've yet to see a radio button control anywhere in the GUI where it would make sense. Anyway, I want to do this right from the ground up. I'm by no means a newbie when it comes to programming in .NET 2010, however, I want the entire solution to be professionally done. I want version control, test projects, project flow, SQL 2008 integration and all the bells and whistles that come with that. I know for a fact that if we had something like that running, not only would development costs and time be slashed four fold, but the possibilities for expansion and performance would sky rocket. (Between the GUI an our DB engine, it can only use ONE CORE! ONE! It's 2012 for goodness sake!) Our business is growing and our current ancient solution just can't keep up, and I'd hate to see our business go down in flames because our programmer is stuck in the 80's and refuses to use anything current. So I ask you guys, the experts and know-it-alls, where do I start? Are there any gems of good books out there in the haystack of all "This for dummies" type of deals? I already have several people backing me in this endeavor, and while it may seem brash to just usurp the current programmers, I'm doing this for the company as a whole.

  • Title of person reporting to CEO responsible for strategy and projects [closed]

    - by user64134
    Case in point: What is the title of the person reporting directly to the CEO and/or CTO, responsible for the overall technical strategy and the overall responsibility for all projects and programs among multiple teams (being led by team leads) in a tech company I'm thinking that it is a mix of a staff and line position - making chief architect being too advisory and not matching the project/program part and VP of engineering a bit too high level?

  • "UML is the worst thing to ever happen to MDD." Why?

    - by Florents
    William Cook in a tweet wrote that: "UML is the worst thing to ever happen to MDD. Fortunately many people now realize this ..." I would like to know the reasoning behind that claim (apparently, I'm not referring to his personal opinion). I've noticed that many people out there don't like UML that much. Also it is worth mentioning that he is in academia, where UML is preety much the holy grail of effective design and modelling.

  • Are there studies on what programming languages does to the brain? [closed]

    - by Eduard Florinescu
    Are there studies on what effects have programming languages on the brain or for that matter any other artificial languages in general, like mathematics ? Speaking from my personal experience I feel very different every time I speak Italian, I feel like a virtuoso on a quest but at the other end when I coded in machine code in debug.exe I felt like the main charcter inp(Movie). Why do I bring this up because I am suspecting that languages affect your mind and popular legends back this up too often: are full of mathematicians that crossed the Rubicon.

  • Why is Evince not displaying application fonts/text for me?

    - by Philippe Fenderson
    Any time I use Evince, it just shows boxes where all the text should be. Instead, it uses the box symbol which I know stands for not being able to find a character. This problem occurs on every menu, and makes it impossible to tell what's going on in any part of the application. I've tried Googling for this problem, but my -fu is weak or it's hard to search for. I'm pretty tech-literate, and I'm running a fairly stock 10.10 install with GNOME.

  • 6 Ways to Modernize Your Customer Experience

    - by Mike Stiles
    If customers have changed, if the way they research and shop have changed, if their expectations have changed, if their ability to act on dissatisfaction has changed, but your customer experience has NOT changed, what was once “good enough” may now be crippling. Well, the customer has changed, and why wouldn’t they? You’ve probably changed too in your role as consumer. There’s more info available, it’s easier to get, there’s more choice, you’re more mobile, you’re more connected, it’s easier to buy, and yes, it’s easier to switch brands if experiences don’t meet your now higher expectations. Thanks to technological advances, we as marketers can increasingly work borderline miracles. But if we’re still not adamantly adopting customer centricity, and if we aren’t making the customer experience paramount amongst business goals, the tech is wasted. A far more modern customer experience is called for. Here are 6 ways to get there: 1. Modern Marketing: Marketing data is aggregated and targeted to the right customers, who are getting personal, relevant communications. In return, you’re getting insight that finally properly attributes revenue to your marketing efforts. 2. Modern Selling: Demand is being driven across all channels with modern selling tools. Productivity is up thanks to coordinated communication and selling, and performance is ever optimized using powerful analytics. 3. Modern CPQ: You’re cross-selling and upselling more effectively since reps and channel partners have been empowered with the ability to quickly, automatically generate 100% accurate, customer-friendly quotes complete with price controls and automated approvals. 4. Modern Commerce: You’re leveraging data and delivering personalized, targeted digital experiences to everyone. You’re attracting more visitors, and you’re able to scale and keep up with the market and control the experience. 5. Modern Service: You’re better serving your customers by making it easier for them to engage with your brand, plus you’re lowering your costs by increasing agent and tech support efficiencies. 6. Modern Social: You’re getting faster, deeper, more accurate insights from social and turning content around faster, which then goes out to the right people at the right time in the right place. You’ve also gotten proactive in your service, and customers love that. For far too many brands, the buying journey of Need, Research, Select, Buy, Use, Recommend across the multiple connect points of Social, Mobile, Store, Call Center, Site, Ecommerce is a disconnected mess. Oracle’s approach to CX is to connect every interaction your customer has with your brand, avoiding the revenue losses lousy customer experiences bring. How important is the experience to customers? 94% are willing to pay more of their hard-earned money to have better ones, while a meager 1% say they get the good, consistent experiences they expect. Brands, your words aren’t as loud anymore, so your actions as they relate to customer experience are going to have to do the talking. @mikestiles @oraclesocialPhoto: Julien Tromeur, freeimages.com

  • SQL: empty string vs NULL value

    - by Jacek Prucia
    I know this subject is a bit controversial and there are a lot of various articles/opinions floating around the internet. Unfortunatelly, most of them assume the person doesn't know what the difference between NULL and empty string is. So they tell stories about surprising results with joins/aggregates and generally do a bit more advanced SQL lessons. By doing this, they absolutely miss the whole point and are therefore useless for me. So hopefully this question and all answers will move subject a bit forward. Let's suppose I have a table with personal information (name, birth, etc) where one of the columns is an email address with varchar type. We assume that for some reason some people might not want to provide an email address. When inserting such data (without email) into the table, there are two available choices: set cell to NULL or set it to empty string (''). Let's assume that I'm aware of all the technical implications of choosing one solution over another and I can create correct SQL queries for either scenario. The problem is even when both values differ on the technical level, they are exactly the same on logical level. After looking at NULL and '' I came to a single conclusion: I don't know email address of the guy. Also no matter how hard i tried, I was not able to sent an e-mail using either NULL or empty string, so apparently most SMTP servers out there agree with my logic. So i tend to use NULL where i don't know the value and consider empty string a bad thing. After some intense discussions with colleagues i came with two questions: am I right in assuming that using empty string for an unknown value is causing a database to "lie" about the facts? To be more precise: using SQL's idea of what is value and what is not, I might come to conclusion: we have e-mail address, just by finding out it is not null. But then later on, when trying to send e-mail I'll come to contradictory conclusion: no, we don't have e-mail address, that @!#$ Database must have been lying! Is there any logical scenario in which an empty string '' could be such a good carrier of important information (besides value and no value), which would be troublesome/inefficient to store by any other way (like additional column). I've seen many posts claiming that sometimes it's good to use empty string along with real values and NULLs, but so far haven't seen a scenario that would be logical (in terms of SQL/DB design). P.S. Some people will be tempted to answer, that it is just a matter of personal taste. I don't agree. To me it is a design decision with important consequences. So i'd like to see answers where opion about this is backed by some logical and/or technical reasons.

  • TSQL formatting - a sure fire way to start a conversation.

    - by fatherjack
    There are probably as many opinions on ways to format code as there are people writing code and I am not here to say that any one is better than any other. Well, that isn't true. I am here to say that one way is better than another but this isn't a matter of preference or personal taste, this is an example of where sloppy formatting can cause TSQL to weird and whacky things but following some simple methods can make your code more reliable and more robust when . Take these two pieces of code, ready...(read more)

  • SQL Triggers and when or when not to use them.

    - by John Mitchell
    When I was originally learning about SQL I was always told, only use triggers if you really need to and opt to use stored procedures instead if possible. Now unfortunately at the time (a good few years ago) I wasn't as curious and caring about fundamentals as I am now so never did ask to the reason why. What's the communities opinion in this? Is it just someone's personal preference, or should triggers be avoided (just like cursors) unless there is a good reason for them.

  • Why should I not do a masters degree

    - by aurel
    I have left university on July 2010 where I studied web design (as we all know you learn more by your self but that’s not the issue at the moment). Since then I have not managed to find a job (apart from a one month work experience), from the way things are going, and by taking into account the fact that all my university friends are in the same situation, I don’t think that I am going to find a job soon (within the industry) Now as we all do, even though I don’t have a job, I am still working on personal projects and try to keep up to date (I don’t need a job or uni to do this) – but I am thinking, because there is not work available, would it be worth going back to uni for a master degree? I know I don’t need it and I know that is unlikely that I will learn anything important, as I believe in self learning, and in most cases it is a lot more effective (but I have to say I don’t mind going back to school) The only reason I am thinking of doing the master is, (and this is where I need your help): If it takes me a year to get a job, then on the interview, would the employer think “what the hell did this guy do since he left university” – now if I go to university that would solve this problem. Or I’m I making up a problem that does not exist Plus, I know that employers need examples of sites that I have been working on, at the moment I only have 3 (as when working on personal projects, where their is not time limit I tend drag things in order to get them perfect, and they never get perfect) – so by going back to uni, then this problem maybe solved I said all this as I have read a lot about the fact that you don’t need to have a masters degree to work on web design market (and I totally agree) but considering my concern, the question is should I do a masters course to avoid just spending hours in my room working and learning in my own (but that it would be hard to convince employers that I was really learning in my room) Maybe because I’m still young age 22 not that old anyway :), but I don’t have the “dream” of being rich, so if I were to tell the truth I don’t really care of the fact that I don’t have a job (at the moment), because regardless, I am working on what I love every day, but I know that in the future when I will need the job I may find it harder to get one, if I neglect doing so now Every time I ask a question that I’m not sure about, I keep going on and on, but I really hope you get what I am trying to get across. By the way the course that I am looking at for a masters says that it would teach me how to do these: e-commerce e-government e-science e-learning I don’t know any of them, a part from e-commerce Thanks

  • When not to use Google Web Toolkit?

    - by Jas
    I'm considering use of GWT on a major in-house web app development project, namely it's major advantage in my eyes is the cross-compilation to Javascript which would (at least theoretically) help my team reduce the size of tech stack by one. However, having been burnt before (like most devs), I would like to hear from programmers who did actually use it on any problems with GWT which would hamper, or limit, it's use within a certain problem domain. When do you not recommend using GWT, and why?
