Which shopping cart / ecommerce platform to choose?

- by fabien7474

I need to build an ecommerce website within a tight budget and schedule. Of course, I have never done that before, so I have googled out what my solutions are and I have concluded that the following were not valid candidates anymore : Magento : Steep learning curve osCommerce : old, bad design, buggy and not user-friendly Zencart, CRE Loaded, CubeCart : based on osCommerce Virtuemart, uberCart, eCart : based on CMS (Joomal, Drupal, WordPress) that is not necessary for my use-case So I finally narrowed down my choices to these solutions : PrestaShop : easy-to-use, great templating engine (smarty) but many modules are not free buy yet indispensable OpenCart : security issues and not a great support from the main developer. See here and here. So, as you can see, I am a little bit confused and if you can help me choosing an easy-to-use, lightweight and cheap (not-necessarily free) ecommerce solution, I would really appreciate. By the way, I am a Java/Grails programmer but I am also familiar with PHP and .NET. (not with Python or Ruby/Rails) EDIT: It seems that this question is more appropriate for the Webmaster StackExchange site. So please move this question to where it belongs (I cannot do that) instead of downvoting it. BTW, I have found out a question quite similar on SO (http://stackoverflow.com/questions/3315638/php-ecommerce-system-which-one-is-easiest-to-modify) which is quite popular.

Should I provide fallbacks for HTML5/CSS3 elements in a web page at this point?

- by Abluescarab

I'm wondering if I should bother providing a fallback for HTML5 tags and attributes and CSS3 styling at this point in time. I know that there's probably still a lot of people out there who use older versions of browsers and HTML5/CSS3 are still fairly new. I read this article: Should I use non-standard tags in a HTML page for highlighting words? and one answer mentioned that people kind of "cheat" with older browsers by using the new tags and attributes, but styling them in CSS to ensure they show up right. This question: Relevance of HTML5: Is now the time? was asked about two years ago and I don't know how relevant it is anymore. For example, I want to use the placeholder and required attributes in a web form I'm building and it has no labels to show what each <input> is. How do I handle this, or do I bother?

Eyes easily get dry and itchy [closed]

- by Lo Wai Lun

I have currently working as a programmer for half a year Very often, I often looking the monitors with natural contrast and brightness. Still when the weather is getting cold, my eyes feel dry and itchy. Sometimes I can see some red 'tree-roots' (capillaries) near iris. At home, i sometimes use my notebook for 13" or Galaxy Nexus Brightness are also natural contrast and brightness , a bit dim How should we take care of our eyes under this scenario?

Who is likely to need the most this high-quality, measurable, reliable approach to software? [closed]

- by Marek Cruz

Software engineering is the application of principles of engineering to software. Trouble is, most of those who like to flatter with the title "software engineer" don't do that. They just keep writing code and patching it until it's stable enough to foist off on users. That's not software engineering. Who is likely to need the most the practice of software engineering? (with all the project planning, requirements engineering, software design, implementation based on the design, testing, deployment, awareness of IEEE standards, metrics, security, dependability, usability, etc.)

What are the IEEE and ACM good for?

- by Joshua Fox

Membership in the IEEE and ACM is sometimes portrayed as a sign of professionalism. But all that is involved, as far as I can tell, is sending them your money. In return, besides the potential resume line, these organizations sponsor conferences and journals. I can always attend a conference or subscribe to or submit a paper to a journal, whether I am a member or not. If being a member makes some of that cheaper, or is a prerequisite for admission then OK, but I still don't see the purpose of these organizations. The answer, as far as I can gather, is that their most important value is to provide some reading material. I'd suggest that this is not worth the money given the wide availability of other valuable reading materials.

Would you use UML if it kept stakeholders from requesting changes frequently?

- by Huperniketes

As much as programmers hate to document their code/system and draw UML (especially, Sequencing, Activity and State machine diagrams) or other diagramming notation, would you agree to do it if it kept managers from requesting a "minor change" every couple of weeks? IOW, would you put together visual models to document the system if it helped you demonstrate to managers what the effect of changes are and why it takes so long to implement them? (Edited to help programmers understand what type of answer I'm looking for.) 2nd edit: Restating my question again, "Would you be willing to use some diagramming notation, against your better nature as a programmer, if it helped you manage change requests?" This question isn't asking if there might be something wrong with the process. It's a given that there's something wrong with the process. Would you be willing to do more work to improve it?

What are the best Microsoft Certifications to start with?

- by emragins

Background I have a bachelors in math and a certification. in C++ from 2007. Since then I've spent a lot of time working with python, C#, and started going through the ASP.NET certification materials. I'm starting to realize that the certification is going to take longer than anticipated and I'm not sure I want to spend the next 4-5 months studying before I have it completed. Most of resume shows teaching/tutoring experience with some low-level administration thrown in. Question If I want to get any programming position, which certifications would be best to start with? What would be the quickest and easiest to obtain, yet represent value for my employer? Are certifications even the way to go? If not, what would you suggest? Update I have several programs that I show off when I can (mostly games), and I'm about 75% through a C# application I hope to have done in the next week. Since most employers simply ask for a resume and not samples, what would be the best way to present the work to them?

Where to find a mentor?

- by Fanatic23

I have been looking around for resources that discuss about mentors, including questions in the stackexchange network. I see that the general response has been to join open source projects and/or check out local user groups if there exists any. Are we sure that joining open source project can get me a mentor? It can grab eyeballs, yes, if the project is exciting enough but a mentor? I am not so sure. What do you guys think? Finally, I'd want my mentor to be in a specific domain as opposed to just being a coding wizard and that makes the search even more difficult. Suggestions?

Preventing possible burnout in a junior dev, or perhaps I'm not doing enough?

- by m.edmondson

I'm a software developer with 5 years experience over 3 companies. Within the last year a junior (brand new to the industry) has started at my current employer. I believe he is an excellent developer, who always delivers and is skilled as solving complex problems. However I'm slightly concerned that he is possibly applying himself too much for the following reasons: He begins work approximately 2 hours before most (and is expected) In his free time he has developed an application that was clearly months worth of work that is specific to our employer I and the team are completely greatful for all he is doing, and is clearly an asset to our team. However I'm worried that this is not sustainable. I can almost see that he has the same enthusiasm that I had when I began coding for work, however over the years I've realised that extra curricular work not only doesn't progress your career, but eats into your all important free time. The question I'm asking is: Should I advise him to take things a bit more slowly? Or perhaps I need to learn from him and do more for my employer out of hours?

Is porting a Windows application to Mac worth it ?

- by mikel

I have a C# Windows application that sells for $35, and fairly regularly receive requests for a version for OS X too. I don't have any experience with Mac so far though, and so am not sure exactly how much work that would involve and if it would be worth it. If anyone's been in a similar position, it'd be very helpful to know: Roughly how many more (%) sales can you expect by porting to Mac ? Would you say it's worth the investment of a new Macbook Pro and the time of learning and porting to Objective-C ? Thanks in advance.

ATI Radeon HD 6870 Driver fails to install default-policy.sh does not support version

- by Rogue Coder

I'm running Ubuntu 11.04 Beta, with everything updated completely. I'm using Ubuntu Classic, because Unity fails to run, supposedly because of my video card. The drivers for the Radeon HD 6870 series is apparently lacking, but I found a post stating the newest version has full support for Ubuntu Natty Narwhal. That post is slightly old, so i grabbed 11.3 for Ubuntu x86 off the ATI website. When I run the installation program, I receive the following error: > ./ati-driver-installer-11-3-x86.x86_64.run Created directory fglrx-install.uREFoO Verifying archive integrity... All good.

Black Hat Hackers vs Programmers?

- by Matt Ridge

This came up with another question I had here, I have decided on a programming verification system that requires a hardware verification system, a software key, and a name/password system. Now people are saying that hackers will bypass any new security, which may be true, but I have a few questions. There has to be a balance between programmers programming and hackers stealing software, otherwise programs wouldn’t be made, and we wouldn’t be where we are today. What is that balance? 5%, 10%, 20%, 50%? What is too much security for the end user? What is too little security so the hacker can just push through without issue? If your software becomes popular, what should you expect or accept as acceptable loss? Why should we accept black hat hackers as a way of life?

Is there a Source Insight alternative?

- by hansioux

I am not a developer, but for my work I trace a lot of codes. It is actually rather difficult reading other people's code, especially for bigger projects. Source Insight is a great application that stores all the symbols in a data base, so you can see a new function being called, click on it and see how the function is written. You can see all the referrer of a object or jump to a caller. You don't need to break the train of thought and think up shell commands just to find these things every time you ran into a new variable/structure/function from some other files. I have it running on WINE, but there are little glitches that sometimes gets in the way. I know people will mention C-scope, I've tried it, but it really isn't the same. So, with so many huge open source projects out there for Ubuntu, are there native tools to help read them efficiently? EDIT: Thanks for the suggestions, but does CODE::BLOCKS or CodeLite provide abilities to see the function that the mouse clicked on without jumping to it, so I can see the caller and callee at the same time?

Building a website, want to use java

- by Robb

I'd like to make a simple-ish website that is essentially a small game. Key strokes are to be processed and sent to a server (already acquired and should support SQL and JSP, I believe) which then translate to a location and written to the DB. SQL queries are to be used to retrieve these locations and written to other clients connected to the website. Their page is to be updated with these locations. I have working knowledge of Java, jQuery/Ajax, SQL and JavaScript but I'm unfamiliar with JSP and how everything hooks up. I'm aware of the MVC paradigm as well. For my little game idea, would these technologies work? Am I over thinking this and can make it much easier to implement? What might be a good tutorial or example to study?

Should I be using WAI-ARIA in my HTML website builds?

- by DBUK

Should I be using WAI-ARIA in my website builds? Will it have any benefit? Is anyone adding 'role' to their code at the moment? The tab, link, checkbox and slider roles, plus many more, aren't available yet for HTML5. From looking at the list of what is available (see below), and what will be coming in the future, it looks like we might be applying roles to a huge amount of tags on our pages. Its not an issue especially if it brings benefit to users using readers etc Also, a side question, will search engines give any benefits to sites using WAI-ARIA? List of safe roles to use (I think) • role="article" • role="banner" • role="complementary" • role="contentinfo" • role="form" • role="heading" • role="main" • role="navigation" • role="search" Examples of usage: <header role="banner"></div>for a main header, banner only allowed once per page <header role="heading"></div>- for all headers after the main one <aside role="complementary"></aside> <form role="search"></form>

What's missing in ASP.NET MVC?

Hello programmers, I think there are not many people who don't think that ASP.NET MVC is one of the greatest technologies Microsoft gave us. It gives full control over the rendered HTML, provides separation of concerns and suits to stateless nature of web. Next versions of framework gaves us new features and tools and it's great, but... what solutions should Microsoft include in new versions of framework? What are biggest gaps in comparison with another web frameworks like PHP or Ruby? What could improve developers productivity? What's missing in ASP.NET MVC?

How to pick a great working team?

- by Javierfdr

I've just finished my master and I'm starting to dig into the laboral world, i.e. learning how programming teams and technology companies work in the real world. I'm starting to design the idea of my own service or product based on free software, and I will require a well coupled, enthusiast and fluid team to build and the idea. My problem is that I'm not sure which would be the best skills to ask for a programming team of 4-5 members. I have many friends and acquaintances, with whom I've worked during my studies. Must of those ones I have in mind are very capable and smart people, with a good logic and programming base, although some of them have some characteristics that I believe that could influtiate negatively in the group: lack of communication, fear to debate ideas, hard to give when debating, lack of structured programming (testing, good commenting, previous design and analysis). Some of them have this negative characteristics, but must of them have a lot of enthusiasm, nice working skills (from an individual point of view), and ability to see the whole picture. The question is: how to pick the best team for a large scale project, with a lot of programming? Which of these negative skills do you think are just too influential? Which can be softened with good leadership? Wich good skills are to be expected? And any other opinion about social and programming skills of a programming team.

How do you overcome your own coding biases when handed legacy code?

- by Bryan M.

As programmers, we often take incredible pride in our skills and hold very strong opinions about what is 'good' code and 'bad' code. At any given point in our careers, we've probably had some legacy system dropped in our laps, and thought 'My god, this code sucks!' because it didn't fit into our notion of what good code should be, despite the fact that it may have well been perfectly functional, maintainable code. How do you prepare yourself mentally when trying to get your head around another programmer's work?

Is Paypal the best solution for payment gateway for a website?

- by Pennf0lio

I have a realty website that needs a payment gateway for their property reservation. The reservation fee range from $500-$600 and about 5-6 people per month. I was wondering if Paypal is the best solution for accepting Payment. What will be the Pros and Cons using Paypal. Paypal was my first choice because It's easy to integrate on my existing website and I wouldn't be minding so much on the security. P.S. It's not a part of the question, But If you can site some realty website that accept payment and would be a good inspiration. It would be highly appreciated. Thanks!

Graduate expectations versus reality

- by Bobby Tables

When choosing what we want to study, and do with our careers and lives, we all have some expectations of what it is going to be like. Now that I've been in the industry for almost a decade, I've been reflecting a bit on what I thought (back when I was studying Computer Science) programming working life was going to be like, and how it's actually turning out to be. My two biggest shocks (or should I say, broken expectations) by far are the sheer amount of maintenance work involved in software, and the overall lack of professionalism: Maintenance: At uni, we were all told that the majority of software work is maintenance of existing systems. So I knew to expect this in the abstract. But I never imagined exactly how overwhelming this would turn out to be. Perhaps it's something I mentally glazed over, and hoped I'd be building cool new stuff from scratch a lot more. But it really is the case that most jobs are overwhelmingly maintenance, bug fixing, and support oriented. Lack of professionalism: At uni, I always had the impression that commercial software work is very process-oriented and stringently engineered. I had images of ISO processes, reams of technical documentation, every feature and bug being strictly documented, and a generally professional environment. It came as a huge shock to realise that most software companies operate no differently to a team of students working on a large semester-long project. And I've worked in both the small agile hack shop, and the medium sized corporate enterprise. While I wouldn't say that it's always been outright "unprofessional", it definitely feels like the software industry (on the whole) is far from the strong engineering discipline that I expected it to be. Has anyone else had similar experiences to this? What are the ways in which your expectations of what our profession would be like were different to the reality?

Does Google AdWords care about duplicate content?

- by Yarin

Our site offers several families of products, all of which have a common set of configurations. For simplicity's sake, we'll say we offer products A, B and C, each with configurations 1, 2 and 3 Products: A, B, C Configurations: 1, 2, 3 We want to create landing page <- ad group combinations that reflect each possible combination of each product and configuration. Each product and each configuration have their own page, and so each landing page would have include the product content and the configuration content: ourproducts.com/A-1 (Contains copy for A and 1) ourproducts.com/A-2 ourproducts.com/A-3 ourproducts.com/B-1 ... etc... As you can see, this will lead to duplicate content across our product pages, though in different combinations. My question is, does this matter from AdWords point of view? Will there be any negative consequence to repeating portions of content this way?

What is the correct way to use g_signal_connect() in C++ for dynamic unity quicklists?

- by hakermania

I want to make my application use dynamic unity quicklists. For building my application I am using C++ and the QtCreator IDE. When a menu action is triggered I want to be able to have access to a non-static function of my MainWindow class so as to be able to update the Graphical User Interface which can be accessed from inside 'normal' MainWindow's functions. So, I am building up my quicklist like this (mainwindow.cpp): void MainWindow::enable_unity_quicklist(){ Unity_Menu = dbusmenu_menuitem_new(); dbusmenu_menuitem_property_set_bool (Unity_Menu, DBUSMENU_MENUITEM_PROP_VISIBLE, FALSE); Unity_Stop = dbusmenu_menuitem_new(); dbusmenu_menuitem_property_set(Unity_Stop, DBUSMENU_MENUITEM_PROP_LABEL, "Stop"); dbusmenu_menuitem_child_append (Unity_Menu, Unity_Stop); g_signal_connect (Unity_Stop, DBUSMENU_MENUITEM_SIGNAL_ITEM_ACTIVATED, G_CALLBACK(&fake_callback), (gpointer)this); if(!unity_entry) unity_entry = unity_launcher_entry_get_for_desktop_id("myapp.desktop"); unity_launcher_entry_set_quicklist(unity_entry, Unity_Menu); dbusmenu_menuitem_property_set_bool(Unity_Menu, DBUSMENU_MENUITEM_PROP_VISIBLE, true); dbusmenu_menuitem_property_set_bool(Unity_Stop, DBUSMENU_MENUITEM_PROP_VISIBLE, true); } void MainWindow::fake_callback(gpointer data){ MainWindow* m = (MainWindow*)data; m->on_stopButton_clicked(); } void MainWindow::on_stopButton_clicked(){ //stopping the process... } mainwindow.h: private slots: void enable_unity_quicklist(); void on_stopButton_clicked(); public slots: static void fake_callback(gpointer data); This suggestion was taken from http://old.nabble.com/Using-g_signal_connect-in-class-td18461823.html The program crashes immediately after I choose the 'Stop' action from the Unity Quicklist. Debugging the program shows that I am not able to access anything MainWindow related inside the on_stopButton_clicked() without crashing. For example, it crashes when doing this check (which is the first 2 lines of code inside this function): if (!ui->stopButton->isEnabled()) return; I have also tested lots of other things that I found at the internet, but nothing of them worked. One interesting solution would be to use gtkmm (http://developer.gnome.org/gtkmm-tutorial/stable/sec-connecting-signal-handlers.html.en) but I am not used at all working on GTK applications (I work solely in Qt) and I don't know if this even suits to my occasion. A compilable example indicating what the problem is can be found at: http://ubuntuone.com/7iKA3wnPmWVp8YNNDLlVQI (3.2Kb) If you are not familiar with the QtCreator IDE, you can compile with the following commands, as long as you have all the needed libraries: cd dynamic_unity_quicklists_test; qmake -project; qmake; make
