  • Developer career feeling like going back in time every new job [closed]

    - by komediant
    Is there a good category for this question? My background is bachelor in ICT and for a hobby I am programming already since I was around twelve I think. Started with QBasic, Pascal, C, Java et cetera. Currently I am working for about eight/nine years. Half academics/medical and half company world. A few years ago I started with frameworks and I began with Grails (underlying Spring/Hibernate), which was a heavenly job, very productive and no hassle. My previous job I developed in pure Spring/Hibernate Java, which was a bit more writing annotations and XML and no conventions like Grails. But still, I did like Spring/Hibernate a lot and the professional setup with a developmentstreet, versioning, Jenkins/Sonar, log4j and a good IDE like IntellIJ. It felt quite 'clear' and organised, although I knew Grails which felt a bit more productive. But...at my current job almost half the code is pure servlet, hard coded JDBC (connections handled by yourself), scriptlets in all JSP pages, no service layer, no versioning, no Maven, HTML in DAO-layer, JAR-hell, no hot swap deployment locally, every change you have to deploy and hope it works fine on the server. All local development needs ugly scriptlet tags to check which environment it is running. Et cetera. Now and then developers work over in the evening - I don't - and still lots of issues are not solved and new projects are waiting. I hear the developers complaining, but somehow they feel like what they have now is "advanced" or they are in a sort of comfore zone. The lead developer seems open for new things, but half of the times he says he can implement MVC-framework features himself instead of using what is already out there. So in short, I currently feel like I miss all the modern framework techniques and that the company is going so slow forward. I just work here for two months now. What I do now is also code some partially ugly stuff, but it goes in completely into my nature and I feel uncomfortable with it. Coding something takes long(er) than estimated and my manager complains about why it takes so long and I feel ashamed for myself needing so much time. Where I was used to just writing a query I now build up whole try catch methods. My manager knows my complaints and the developers do so too. There will come a meeting to line out plans for 2013 on technology and the issues I and the company are facing. I am not looking for another job yet, it's close to wehre I live and the economy is fragile. Does anyone else have had this kind of career, like feeling going backwards witch technology? And how did you cope with it?

  • Understanding the SQL Server 2008 R2 Installation Center

    - by Enrique Lima
    What is available to us through those links?  Have you taken the time to explore and identify what could be useful to you? One of many gems that has come to my attention is the possibility of provisioning SQL Server to work in an image based environment (hint: Virtualization Template perhaps?!?).   Planning: Includes requirements information, documentation, how to guides, online documentation installation and other tools. Among the other tools you will find the System Configuration checker and The Upgrade Advisor. Both tools very important to ensure your deployment and installation would be successful.     Installation:  This sections focuses on getting installations going, from standalone to cluster when it comes to new instances.  Add new nodes to an existing cluster, and also perform upgrades (in this case to SQL Server 2008 R2).  Also part of this is the option to find updates available.   Maintenance: We find in this section, options that will assist us in tasks like repairing corrupt installations to removing nodes from a cluster. An option that is interesting (and we should discuss benefits later in another post) is to be able to do an Edition Upgrade, this is a feature expansion and addition based on your product installation (Developer to Enterprise, for example)   Tools:  From the System Configuration Checker to identify readiness for deployment in a successful manner, to being able to report on features installed.  And being able to run upgrades of existing packages developed in the 2005 offering to the 2008 R2 release for SSIS.   Resources: Useful and essential links to gather information and guidance.   Advanced: Here is where it gets interesting.  I break this down into 3 main groups: Installation Automation: When you install SQL Server there is a configuration file that gets dropped (ConfigurationFile.ini) that would allow for you to perform automated installations.  There are switches and options that go with this to have that process working. Cluster configuration for Sysprep: Create images that are cluster ready, 2 options, start the prep work, and then the complete once at the final destination. Stand-alone configuration for Sysprep:  Like the clustering counterpart, 2 options, prep and complete.  Giving you the option to create standard templates for your SQL Server deployments. I find it fitting that the 3 topics listed here should (and will) be additional topics I will discuss.   Options: Very clear and specific about what this means. Select the Processor Type or the Installation Media Root Path.

  • The difference

    So with the CTP tools available, weve been building a few apps, just to get a feel for the tools and whats supported in the framework.  Whats been great is that everything is fairly familiar and consistent, largely to do with the .net framework and Microsofts focus on providing good tools.  Weve produced mobile applications, mostly in concept form, for Windows Phone Classic, iPhone and Android but never so quickly and not of such high quality and visual impression.  I attribute some of this obviously to our familiarity to the Microsoft platform and tools.  Though when you look at the designs our team has produced, it becomes clear that this is not just another mobile application container.                                                            The Metro design language implores content prominence with fluid motion and transitions, with a crisp font and easily organized features and services placement.  In addition to a purposeful right edge tease, where the intent is for users to discover new premium content and services.   The concept that enables this is called hubs, building application with hubs changes your thinking from a single mobile application task, to thinking creatively about a mobile experience. Its engaging to think of the other brands and industry verticals that will take advantage of this core feature.  Combine this with Windows Phone 7 live tiles, more on that later, and you have a recipe for a solid mobile services platform.                                                              This so much more fun and liberating than my icon on a gridDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • The term "interface" in C++

    - by Flexo
    Java makes a clear distinction between class and interface. (I believe C# does also, but I have no experience with it). When writing C++ however there is no language enforced distinction between class and interface. Consequently I've always viewed interface as a workaround for the lack of multiple inheritance in Java. Making such a distinction feels arbitrary and meaningless in C++. I've always tended to go with the "write things in the most obvious way" approach, so if in C++ I've got what might be called an interface in Java, e.g.: class Foo { public: virtual void doStuff() = 0; ~Foo() = 0; }; and I then decided that most implementers of Foo wanted to share some common functionality I would probably write: class Foo { public: virtual void doStuff() = 0; ~Foo() {} protected: // If it needs this to do its thing: int internalHelperThing(int); // Or if it doesn't need the this pointer: static int someOtherHelper(int); }; Which then makes this not an interface in the Java sense anymore. Instead C++ has two important concepts, related to the same underlying inheritance problem: virtual inhertiance Classes with no member variables can occupy no extra space when used as a base "Base class subobjects may have zero size" Reference Of those I try to avoid #1 wherever possible - it's rare to encounter a scenario where that genuinely is the "cleanest" design. #2 is however a subtle, but important difference between my understanding of the term "interface" and the C++ language features. As a result of this I currently (almost) never refer to things as "interfaces" in C++ and talk in terms of base classes and their sizes. I would say that in the context of C++ "interface" is a misnomer. It has come to my attention though that not many people make such a distinction. Do I stand to lose anything by allowing (e.g. protected) non-virtual functions to exist within an "interface" in C++? (My feeling is the exactly the opposite - a more natural location for shared code) Is the term "interface" meaningful in C++ - does it imply only pure virtual or would it be fair to call C++ classes with no member variables an interface still?

  • Will not supporting IE or older browsers drive away potential visitors/users of my site? [closed]

    - by XToro
    Normally a SO browser but this question doesn't fit there, hopefully it fits here. I just want to ask from web designers' point of view if it's wrong to not care about supporting Internet Explorer or older browsers. The site I'm designing looks great in all browsers except IE9-. There are certain things that IE doesn't support or behave like other browsers; webkit stuff, some CSS styles, drop-and-drop files from OS etc etc, but it all works great in Safari, FireFox, Chrome etc. Should I be that concerned? I know there are several people that use IE, but it's limitations have just been causing me more work by having to come up with workarounds. From what I've read, many of the issues I've been having should be solved with IE10, but not everybody keeps up to date. I know of several people who are still using IE6! Again, I'm hoping this is the right place to ask a question like this, and if not, please point me to the right stack exchange site instead of just downvoting me. Thanks! EDIT: Upon further research.... So far this year, IE(all versions) and Chrome have been neck and neck as the top, with IE only squeaking by Chrome, and FireFox a close 3rd. But looking at the top 10 browsers, IE6 doesn't even show up on this list in which the lowest percentage is 1.92%. Source : http://www.w3counter.com/globalstats.php?year=2012&month=7 Having a look at this other site, IE6 shows up in 11th place out of 12, just before "Other" http://www.sitepoint.com/browser-trends-february-2012/ This makes me a little more wary of not spending more time on IE compatibility. However, my site will not be going to a live beta until October or November, and I'm hoping that IE10 will have more features coded into it. Currently, I've written my upload page which is a "drag-and-drop files from the OS" type to simply display "IE is not supported", leaving no other option for IE users to upload pictures because I've spent so much time writing the uploader which does many things other than just upload the files. I will be changing this kinda cold "Access Denied" to a suggestion to upgrade, or install other browsers, with download links for each. Big thanks for the posts here and the interesting links!

  • Ad-hoc reporting similar to Microstrategy/Pentaho - is OLAP really the only choice (is OLAP even sufficient)?

    - by TheBeefMightBeTough
    So I'm getting ready to develop an API in Java that will provide all dimensions, metrics, hierarchies, etc to a user such that they can pick and choose what they want (say, e.g., dimensions of Location (a store) and Weekly, and the metric Product Sales $), provide their choices to the api, and have it spit out an object that contains the answer to their question (the object would probably be a set of cells). I don't even believe there will be much drill up/down. The data warehouse the APIwill interface with is in a standard form (FACT tables, dimensions, star schema format). My question is, is an OLAP framework such as Mondrian the only way to achieve something akin to ad-hoc reporting? I can envisage a really large Cube (or VirtualCube) that contains most of the dimensions and metrics the user could ever want, which would give the illusion of ad-hoc reporting. The problem is that there is a ton of setup to do (so much XML) to get the framework to work with the data. Further it requires specific knowledge, such as MDX, and even moreso learning the framework peculiars (Mondrian API). Finally, I am not positive it will scale much better than simply making queries against a SQL database. OLAP to me feels like very old technology. Is performance really an issue anymore? The alternative I can think of would be dynamic SQL. If the existing tables in the data warehouse conform to a naming scheme (FACT_, DIM_, etc), or if a very simple config file/ database table containing config information existed that stored which tables are fact tables, which are dimensions, and what metrics are available, then couldn't the api read from that and assembly the appropriate sql query? Would this necessarily be harder than learning MDX, Mondrian (or another OLAP framework), and creating all the cubes? In general, I feel that OLAP is at the same time too powerful (supports drill up/down, complex functions) and outdated and am reluctant to base my architecture on it. However, I am unsure if the alternative(s), such as rolling my own ad-hoc reporting framework using dynamic SQL would remove any complexity while still fulfilling requirements, both functional and non-functional (e.g., scalability; some FACT tables have many millions of rows). I also wonder about other techniques (e.g., hive). Has anyone here tried to do ad-hoc reporting? Any advice? I expect this project to take a pretty long time (3 months min, but probably longer), so I just do not want to commit to an architecture without being absolutely sure of its pros and cons. Thanks so much.

  • Can Anything be Done to Make Improv (a 1993 Win 3.1 App) handle larger Files?

    - by user75185
    My very favorite spradsheet is Improv, a 1993 Windows 3.1 application. It still puts Excel to shame for building spreadsheets and writing formulas. The only problem is because Improv was written when 1 Meg of RAM was state of the art, it becomes unstable when working with larger spreadsheets and often crashes and/or corrupts the data file. I am working on a project that greatly exceeds Improv's limits. Although it will ultimately require more robust databasing capability, I could save a lot of critical time if I could delay that headache and continue working in Improv for now. To that end, I moved to the only product I could find that comes close, Quantrix, which is nothing more than Improv updated to handle large spreadsheets and utilize today's technologies. The problems with Quantrix are its speed (significantly slower than Improv) and its $1000 price (which I cannot afford). I have already had 3 15 day extensions after the initial 30 day trial, so my time to use Quantrix as a bridge is at its end. Searches for Improv over the years have gotten me nowhere and, not surprisingly after reading some posts on this site, I got nothing for the money and time invested to find a programmer to write code to "fix" this problem. Improv is freely available as "abandonware" at http://vetusware.com/download/LotusImprov2.1/?id=5797 , and the best background info can be found on Wikipedia and at "Moose's Greatest Software Products of All Time - Lotus Improv" http://moosevalley.fhost.com.au/mooses_review_page_lotus_improv.html It is critically urgent for me to focus on analyzing the data asap. Working in a stable Improv would, without question, be the fastest route. To that end, I am looking for answers to the following questions and anything else that might be helpful: 1) Is it lawful to hire someone to fix Improv for my own use? If so, 2) About how much should it cost? 3) About how long should it take? 4) What skills should I be looking for &/or how should a post be worded? 5) Is there a niche site where it should it be posted? 6) What questions can I ask to quickly screen candidates? Since I am not a programmer, I need questions the answers to which leave no room to confuse me, whether intentional or not. For example, what tools or players should someone with an acceptable competency level have knowledge of?

  • Are there new flexible texteditors? [closed]

    - by RParadox
    Vi(m) and Emacs are almost 40 years old. Why are they still the standard, and what attempts have been made at coming up with a new flexible editor? Are there any features which can not be built into vim/emacs? My question is similar to this one: Time to drop Emacs and vi? No one had a suggestion, which surprises me. I would have thought that the core of a texteditor is very small and that people brew their own. Perhaps nobody wants to deal with supporting all the modes? Edit to clarify my question: Instead of writing modes and scripts I ask myself, why there is not a much lightweight project, which lets people custom the editor more directly? Vim has 365395 LOC (C lines all included), Emacs 1.5 million LOC. Why is there a project with say 50k LOC, which is the core, why people can use more freely? Perhaps there is such project, I haven't looked very far. I thought about putting together modules from Vim myself and experimenting with some ideas. The core of editing shouldn't be more than 10k? Vim has a lot optimizations which is really an overkill nowadays. Basically I'm looking for a code base for my own editor and Vi/Emacs are I believe not intended to be used in this way. Bill Joy said the following about vi. http://web.cecs.pdx.edu/~kirkenda/joy84.html The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands. In some sense, its backwards from the kind of thing you'd get from a mouse-oriented thing. I think multiple levels of undo would be wonderful, too. But fundamentally, vi is still ed inside. You can't really fool it. Its like one of those pinatas - things that have candy inside but has layer after layer of paper mache on top. It doesn't really have a unified concept. I think if I were going to go back - I wouldn't go back, but start over again.

  • Programming tourism

    - by Andrew_B
    I'm going on vacation to Paris, France for 10 days. Actually, it's my girlfriend's wish to go there but I'm not very interested in visiting, sightseeing, etc. Recently, I came up with an idea of trying to do something like programming tourism. :) I'd like to do something related to programming in a startup-like company. I do not want a salary or any kind of compensation. I want to overview process, social aspects, environment and "what it feels like" to development software in another country. I'm from Russia. I've been a software developer since 2003. I prefer C#4 but I'm ready to use anything Turing-complete. I have some MS certifications and am familiar with all .NETs since 1.1. Currently I'm finishing PhD in CS. I'm interested in multidimensional indexing and I can turn any piece of data and code to OLAP system. :) But it'd take too much time. What can I do? I have no more than one week. I want a totally complete project in a short amount of time. Implement some features in well-tested project Do a code review Debug memory, performance and concurrency issues Do unit testing So, about the questions: Is it legal? I'm ready to sign NDA if it's necessary. I'll have tourist visa. Is it possible? I'm really sure that bureaucratic companies with lots of HRs and PMs will not allow such experiments. But small companies can afford it. I'm ready to guarantee support on my code after leaving home :) P.S. I still havn't started learning French :) I hope it will not take too much time :) P.P.S. Yes, it's girlfriend-approved. What's in it for me? It's fun. It's fun to see new systems and people who created them. It's fun to complete meaningful things. Quickly. What's in it for them? Feature, debug, review or test. If my short-term colleagues will like this style of working I can invite them to make same trip into my company :) I think in Russia it's even more exciting :)

  • What is hiberfil.sys and How Do I Delete It?

    - by The Geek
    You’re no doubt reading this article because there’s a gigantic hiberfil.sys file sitting in the root of your drive, and you want to get rid of it to free up some space… but you can’t! Luckily, you actually can delete it, and today we’ll show you how. The more memory you have in your PC, the bigger the file will be. So What is hiberfil.sys Anyway? Windows has two power management modes that you can choose from: one is Sleep Mode, which keeps the PC running in a low power state so you can almost instantly get back to what you were working on. The other is Hibernate mode, which completely writes the memory out to the hard drive, and then powers the PC down entirely, so you can even take the battery out, put it back in, start back up, and be right back where you were. Hibernate mode uses the hiberfil.sys file to store the the current state (memory) of the PC, and since it’s managed by Windows, you can’t delete the file. So if you never use it, and want to disable Hibernate mode, keep reading. Personally I stick with Sleep Mode the vast majority of the time, but I do use Hibernate quite often. Disable Hibernate (and Delete hiberfil.sys) in Windows 7 or Vista You’ll need to open an administrator mode command prompt by right-clicking on the command prompt in the start menu, and then choosing Run as Administrator. Once you’re there, type in the following command: powercfg -h off You should immediately notice that the Hibernate option is gone from the Shut down menu. You’ll also notice that the file is magically gone! For more about dealing with Hibernate like setting how long it takes to head into Hibernate mode, you can check out our article on How to Manage Hibernate Mode in Windows 7. Disabling Hibernate Mode in Windows XP It’s a lot easier in Windows XP to get rid of Hibernate mode… in fact, we’ve already covered it before, but we’ll cover it again. Just head into Control Panel –> Power Options, and then find the Hibernate tab. Uncheck the box, reboot your PC, and then you can delete the hiberfil.sys file.

  • database independent coding framework options?

    - by statirasystems
    Background: I have not programmed in a while besides doing VBA and a little VB.NET. So please forgive my language use. I'm green and have a head cold. I am reading all I can now, but I have no programming circles to draw from. The information I am providing is to help guide you to what I am looking for. I am not confident I can ask the question properly. Story: I have four different projects that I am starting. Obviously I won't be working on all at the same time however they each will have similar needs and be inter related. They are as follows: Desktop Environment/System User Interface - basically a product that runs on major computers via mono or .net that unifies the look and functions. In the context of the up coming question it would be able to directly access data of various types. It would work in tandum with my office suite, system manager, and network application framework. Office Suite - technically it would not be a suite since I will be doing it from one interfacel except for the Communications Application. As far as the question, it will need to be able to link to various data sources for storing files and using, manipulating, and presenting information. System Manager - an intellegent system to manage and administer the entire network and all equipment. As far as the question, needs to be able to access data for archiving and and for accessing it's own settings stored in various formats, sql or xml. Network Application Framework - A complete system that can be used for ERP, CRM, CMS, Errata, File Management, and so on. As to the question to be able to access it's own or interlink with existing applications. Requirement: C#, Simplifies and reduces coding, use the same code to access diffent databases(ie MySQL, MS SQL, ACCESS, XML, ...), Mono would be nice but not a must, Question: What librarys, frameworks, or other options would be able to help with this? Is there a good resource to guide me? I don't want arguing over what is best, just information to help me further understand and make an educated decision.

  • Development Approach: User Interface In or Domain Model Out?

    - by Berin Loritsch
    While I've never delivered anything using Smalltalk, my brief time playing with it has definitely left its mark. The only way to describe the experience is MVC the way it was meant to be. Essentially, all the heavy lifting for your application is done in the business objects (or domain model if you are so inclined). The standard controls are bound to the business objects in some way. For example, a text box is mapped to an object's field (the field itself is an object so it's easy to do). A button would mapped to a method. This is all done with a very simple and natural API. We don't have to think about binding objects, etc. It just works. Yet, in many newer languages and APIs you are forced to think from the outside in. First with C++ and MFC, and now with C# and WPF, Microsoft has gotten it's developer world hooked on GUI builders where you build your application by implementing event handlers. Java Swing development isn't so different, only you are writing the code to instantiate the controls on the form yourself. For some projects, there may never even be a domain model--just event handlers. I've been in and around this model for most of my carreer. Each way forces you to think differently. With the Smalltalk approach, your domain is smart while your GUI is dumb. With the default VisualStudio approach, your GUI is smart while your domain model (if it exists) is rather anemic. Many developers that I work with see value in the Smalltalk approach, and try to shoehorn that approach into the VisualStudio environment. WPF has some dynamic binding features that makes it possible; but there are limitations. Inevitably some code that belongs in the domain model ends up in the GUI classes. So, which way do you design/develop your code? Why? GUI first. User interaction is paramount. Domain first. I need to make sure the system is correct before we put a UI on it. There's pros and cons for either approach. Domain model fits in there with crystal cathedrals and pie in the sky. GUI fits in there with quick and dirty (sometimes really dirty). And for an added bonus: How do you make sure the code is maintainable?

  • ADF Real World Developers Guide Book Review

    - by Grant Ronald
    I'm half way through my review of "Oracle ADF Real World Developer's Guide" by Jobinesh Purushothaman - unfortunately some work deadlines de-railed me from having completed my review by now but here goes.  First thing, Jobinesh works in the Oracle Product Management team with me, so is a colleague. That declaration aside, its clear that this is someone who has done the "real world" side of ADF development and that comes out in the book. In this book he addresses both the newbies and the experience developers alike.  He introduces the ADF building blocks like entity objects and view obejcts, but also goes into some of the nitty gritty details as well.  There is a pro and con to this approach; having only just learned about an entity or view object, you might then be blown away by some of the lower details of coding or lifecycle.  In that respect, you might consider this a book which you could read 3 or 4 times; maybe skipping some elements in the first read but on the next read you have a better grounding to learn the more advanced topics. One of the key issues he addresses is breaking down what happens behind the scenes.  At first, this may not seem important since you trust the framework to do everything for you - but having an understanding of what goes on is essential as you move through development.  For example, page 58 he explains the full lifecycle of what happens when you execute a query.  I think this is a great feature of his book. You see this elsewhere, for example he explains the full lifecycle of what goes on when a page is accessed : which files are involved,the JSF lifecycle etc. He also sprinkes the book with some best practices and advice which go beyond the standard features of ADF and really hits the mark in terms of "real world" advice. So in summary, this is a great ADF book, well written and covering a mass of information.  If you are brand new to ADF its still valid given it does start with the basics.  But you might want to read the book 2 or 3 times, skipping the advanced stuff on the first read.  For those who have some basics already then its going to be an awesome way to cement your knowledge and take it to the next levels.  And for the ADF experts, you are still going to pick up some great ADF nuggets.  Advice: every ADF developer should have one!

  • Trying to find resources to learn how to test software [closed]

    - by Davek804
    First off, yes this is a general question, and I'd be perfectly happy to move this to another portion of SE, but I didn't see a more fitting sub. Basically, I am hoping a more experienced QA tester can come along and really fill in some basics for me. So far, websites seem to be sparse in terms of explaining languages involved, basic practices, etc. So, I'm sorry in advance if this is too general, but towards the end of this post I ask some specific questions if it's just absolutely unacceptable to speak in general terms. I just landed a position as Junior Systems and QA Engineer with a social media startup. Their QA and testing is almost nonexistent, so if I do a good job, I imagine I'll find a lot of bugs and have a secure role in the business. I'm pretty good with the systems aspect of my role, but I need to learn more about the QA and testing aspects. We run hardware that's touchscreen based - the user can use and interact with the devices. So, in terms of my QA role, in the short term, I need to build scripts to test the hardware/software as a 'user' to try to uncover bugs. First off, what language should these scripts be written in? Does anyone have some examples? What about the longer term 'automated testing'? I'm familiar with regression testing as the developer adds in new features, sure, but the 50,000 other types of testing, not so much. Most of our hardware runs dotnet/C# code, with some of the servers running Java - but I don't expect to need to run tests on the Java side at this point. I hope to meet with one developer today and try to get a good idea of the output from the hardware so that I can 'mock' this data that gets sent to servers, to try to bugtest. Eventually, we will be moving the hardware to be closer to where I live and work, so that I can test virtually and on real hardware. So a lot of the bugs we're dealing with now are like this: the Local Server, which kiosks report their data to gets updated from the kiosks, but the remote server does not. Or, vis versa when the user registers on a kiosk, the remote server updates but the local server does not. But yeah, without much more detail, I imagine a lot of this info isn't helpful. I've bought a book "How Google Tests Software", but it's really a book more about 'how their software testing is different from Microsoft'. It doesn't teach how to test so much as why their methods are better. Does anyone have a good book that I can buy? An ebook maybe? My local Barnes and Noble kinda had a terrible selection. I also figure a book from 2005 is not necessarily that good either.

  • Help yourself . if you like

    - by rachelp
    At Red Gate we enjoy talking to our customers. Really! If you've read recent blog posts by members of some of our customer-facing teams, you'll have spotted the pleasure they take in their work. In case you missed those posts, here they are: From our Finance team: Finance: Friends, not foes! From our reception desk: The Front line of Communication However, we recognise that sometimes our customers would like to be able to solve their problems or answer their questions without talking to us - they're in a hurry, it's outside office hours . or perhaps they just prefer not to pick up the phone and call.   Self-service customer care So we've begun a programme of work to enable more self-service; whether it's finding the answer to a "how do i.?" question or getting access to a record of what product licenses they own, we want to make it much easier for our customers to get hold of this information for themselves. If they want to.   Phase 1: make it easier to find information We decided to start by tackling findability. We've got loads of useful information on our website, but it's sometimes difficult to find, so we've been working on improving our site search. Step 1 has been to replace the search engine, clean up the search UI, and make it consistent across the site. We're nearly there! The idea is that if we improve the site search it will be easier - and much more pleasant - for people to find the information they need. The new search will go live some time in April, and then we'll be gathering feedback, looking at web analytics (more about this in an earlier article), and working out what improvements we still need to make. We'd love to hear what you think, so do give your feedback or drop us a line. Or pick up the phone and call, if you like.   What do you think? While I've got your attention, I'd love to hear what people think about self-service customer care. Do you like to call, email, live chat . or do you prefer to dig around and find out answers yourself? Who's getting it right: what self-service sites do you like? p.s. Watch this space for news of phase 2.

  • Differences between a retail and wholesale website, and how difficult would it be to integrate them? [closed]

    - by kmy
    I was told to come here for some guidance, I know that my questions can be quite broad, but I just really want some kind of direction to go towards (links, articles, etc). So here it goes: For the past month I have been planning and started implementing a wholesale website, but plans got changed on me and I need to allow both retail and wholesale orders which will also depend on whether the account is a regular customer or also has a seller account. There are various types of products and it has been decided that I would use subcategories as tables to organize them and allow various specific item fields. So here are some of my specific questions: How different is the database structure for each item to be available for both wholesale and retail? Will it just be adding a quantity column and have two different pricing, or much more complicated? I am unaware if there's any price tables but would that be more difficult? They use Quickbooks POS software, how difficult/inefficient will it be to update inventory quantities if they have like 2000-4000 products? And what would be the best ways to extract the information and update the system? I know it export an excel spreadsheet so maybe a suggested php plugin for it? How difficult is this project in your professional opinion, and how big should a team usually be? (At the moment it is just me.) Projected time for planning, implementation, and quality assurance in accordance to team size? I am an entry level developer and I know that I do not have enough knowledge to direct myself on this website...What kind of web developer skills will I need to find to help me? (My company is willing to hire people to get this website done as fast as possible.) Also, what would be some great questionnaires to ask the product stakeholder about what he wants from the website? (He has made it clear he is neither computer or internet savvy...) Sorry for the amount of questions, I'm an entry level web developer and do not have a senior to look up to for guidance. I have knowledge in HTML, CSS, Javascript, jQuery, PHP, MySQL, phpMyAdmin. I have never used any frameworks like Zend, Magento, etc, and is doing this all from scratch. So far the website is built in an object oriented way, MVC architecture to the best of my abilities, but I have many doubts because I would really want to have this done right. If I have been unclear on some parts please tell me and I'll add more detail. I'm sure I'll have more additional questions later on, if anyone is open to that please tell me. Thanks in advance!

  • Watchguard SSL Certificate problems

    - by Bill Best
    We recently purchased a Watchguard XTM 510. The hope is to replace our ISA 2006 proxy with this UTM product. We are having some issues with secured sites in our test setup. Currently We are still running traffic through the ISA server and I have the Watchguard also setup to be connected to the network. Where we run into problems is when I set in ISA the HTTPS site's location to be forwarded through the XTM, I get a certificate could not be validated error. Therefore I think Ive narrowed it down to two possibilities. One, the certificate needs to be installed on the XTM. Im not 100% sure this is the case as I believe this should just be acting as strictly a proxy and forwarding all the traffic through no questions asked. Either way if I try to import a certificate to the XTM I always get a certificate validation failed error message. These are generally converted pfx to pem files. Second, the XTM CA certificate needs to be installed on the ISA server so that they may communicate. I have done this but it didn't seem to do anything. I believe this should be working and was hoping someone has struggled through this before.

  • iScsiPrt error event ID 5

    - by AZee
    Event Log: "Failed to setup initiator portal. Error status is given in the dump data." This is being recorded every 3/100's of a second. We are using MS iSCSI Initiator on Windows Server 2003, Dell 2970 w/4GB (PAE). I am sure that this was configured by Dell initially. I have no idea what changes or mods were made since the company installed this machine until now. (I'm a new User so the lovely and vibrant screen images had to be removed. They were quite pretty and I am sure you would have been very moved and appreciative of them.) It appears that everything is installed correctly and the 5TB bound volume is accessible but I have never worked with iScsi before so I plead total ignorance. In searching I have found this to be a fairly sparce and bland documented subject. I'd like two things... First, to get rid of the error msg being logged. MS says it can be ignored if everything is working but it chews up resources logging it and I don't feel comfortable about any errors on my servers. I want to correct whatever is causing this problem. Secondly, being totally green to this, I would like to confirm that the setup is optimized and we are taking advantage of all features available. Although there are 3 NIC's in this machine it appears that the initiator is only configured for the Broadcom BMC5708C NetXtreme II on our 10.90.1.#, the other 2 NICS are 1GB on the 192.168.0.#. Would additional targets improve performance? If someone who is experienced in configuring the Microsoft iScsi Initiator can help I would really appreciate it since, as I mentioned, everything I have come across has not been of any value at all. Thanks! ~AZ

  • High CPU usage by 'svchost.exe' and 'coreServiceShell.exe'

    - by kush.impetus
    I am having a laptop running on Windows 7 Ultimate 32-bit. Since past few days, my laptop is facing a serious problem. Whenever I connect to Internet, either svchost.exe or coreServiceShell.exe or both hog the CPU. The coreServiceShell.exe consumes a lot of RAM also. Going into the details, I found that high CPU usage of svchost.exe is caused by Network Location Awareness service. And the high CPU usage of coreServiceShell.exe is caused by Trend Micro Titanium Internet Security 2012. That kind'a makes me think that Trend Micro may be the root of the problem. After further testing, I found that if I use IE or Firefox to browse the Internet, immediately after connecting to Internet, things are normal. See and But if I use Google Chrome, the coreServiceShell.exe hogs both CPU and RAM. At this point, if I disconnect the Internet, the CPU and RAM usage by coreServiceShell.exe continues to be high till I close the Chrome. Also, when I close the Chrome, while Internet is connected, svchost.exe continues to hog CPU but coreServiceShell.exe leaves the race. That makes think that Chrome is the root of the problem, but again, tracing coreServiceShell.exe takes me back to Trend Micro Internet Security. Stopping the Protection by the Trend Micro Internet Security doesn't help either (I am not able to stop its services though). I have updated the Chrome, but no help. I just can't figure out who is the culprit. I can't do without the Google Chrome (of course, by not using it) because of its immensely useful and indispensable features both during browsing and development. Secondly, I can't uninstall the Trend Micro Internet security Suite since it still has few months before it expires and is proving me reliable protection. What could be the cause of the problem and what can I do to resolve this? Thanks in advance
