• Webshop for digital goods with voucher / gift card system [duplicate]

  - by Kelzama

  This question already has an answer here: Which Ecommerce Script Should I Use? 1 answer I'm searching for a webshop which provides the following: The shop offers digital goods (like mp3) User can buy a voucher / gift card @Reseller (Or there is a code provided in the CD) User can enter his code @ webshop and gets the download (unregistered) User can enter his code @ webshop and download is added to his/her library (registered) optional: Resellers can buy codes from the Webshop I already tried prestashop as it looks quite nice. But it needs a lot of custom programming (and has a very strange voucher-system). Customer has to add the File into the basket and add the voucher at checkout. I want to skip that ;) Is there a Webshop (Or CMS + Plugin) which provides the things I need? (it could also be a CMS with a Storage/Folder Plugin (like joomla + K2) and a possibility to activate downloads via unique Codes.) Any ideas are highly appreciated :) Thanks in advance.

• sku code as description in Google Analytics

  - by dreagan

  In the Google Analytics ecommerce tracing script you must provide for every item and SKU code. I have this code for every product I'm selling and up until now I have always provided it in the _addItem method. But when reviewing that data in the ecommerce module of Google Analytics, I have no real, no readable data about my SKU sales. I know what product has been sold, due to the product name I provide. But when clicking through to the SKU-level, I know nothing more, since all I can see there are SKU codes. Is it possible and wise to replace the SKU code with the following template? "product-name colour-name size-name" This way, it should still be a unique field, but more readable afterwards.

• Oracle Sequences

  - by jkrebsbach

  Reminder to myself - SQL Server has nice index columns directly tied to their tables. Oracle has sequences that are islands to themselves. select seq_name.currval from dual; select seq_name.nextval from dual; currval - return current number at top of sequence nextval - increment sequence by 1, return new number   therefore - to create functionality in oracle similar to an index column - OPTION A) - Create insert trigger: CREATE OR REPLACE TRIGGER dept_bir BEFORE INSERT ON departments FOR EACH ROW WHEN (new.id IS NULL) BEGIN SELECT dept_seq.NEXTVAL INTO :new.id FROM dual; END; This will handle creating a unique identity, but will not necessarily inform process flow of identity without additional logic. OPTION B) - Select indentity into temp variable, insert whole item into tab **** When attemptint to query currval, the below error was being thrown - SELECT seq_name.currval from dual; ERROR : TABLE OR VIEW DOES NOT EXIST *** Although Oracle sys tables may have access to the sequences, that isn't to say the Oracle user may have access to those sequences - verify permissions when the system can't see object that are being reported in the object explorer.

• When should I use AtomPub?

  - by Gary Rowe

  I have been conducting some research into RESTful web service design and I've reached what I think is a key decision point so I thought I'd offer it up to the community to get some advice. In keeping with the principles of a RESTful architecture I want to present a discoverable API, so I will be supporting the various HTTP verbs as fully as possible. My difficulty comes with the choice of representation of those resources. You see, it would be easy for me to come up with my own API that covers how search results are to be presented and how links to other resources are provided, but this would be unique to my application. I've read about the Atom Publishing Protocol (RFC 5023), and how OData promotes its use, but it seems to add an extra level of abstraction over what is (currently) a rather simple API. So my question is, when should a developer select AtomPub as their choice of representation - if at all? And if not, what is the current recommended approach?

• Why is implementing copy-paste in a touch screen based smartphone such a big deal?

  - by EpsilonVector

  I'm not entirely sure this is on-topic, but it definitely needs a programmer's understanding to be answered, and deals with general development (for a specific scenario) as opposed to a specific piece of code. In a way it also translates into "what are the challenges in doing X in a touch screen app", and similar questions have been asked here in the past. So here it is: When Apple didn't implement copy-pasting on the iPhone since version 1 I just assumed it was a UI issue- they were waiting until they figured out a good UI for it. But now the idea is out there, and Microsoft still released Windows Phone 7 without copy-pasting, promising it'll be ready in a few months. My question is: why does this takes a few months to implement? Are there some technological challenges that are unique to programming for a touch screen that I'm not familiar with?

• Simple issue tracker for 1-2 developers

  - by devoured elysium

  (I'm not sure whether this pertains to the realm of programmers@se or so@se) I'm currently working mostly alone on a project (in Java). I'm mostly alone as I have an advisor that gives me high level instructions on what to do, and will seldom make any code contribution. She will code in a couple of acceptance tests from time to time, though. I've never used an Issue Tracker before, and was thinking about starting to use one now, as I'd like to have a place where I can log possible bugs I find and keep track of them in a centralized manner. Would it be possible to integrate the issue tracker with Eclipse, better yet. So here are the constraints: It's NOT a open-source project. Our code is not to be shared with anyone! we are and will be using Subversion; we have our own Subversion server and we will keep using this same Subversion server; it must be free; it must allow at least 2 users. What is your advice on what to pick? I'm looking for the simplest solution available!

• How to transform gameObjects in array?

  - by user1764781

  I have an array of available gameObjects in the scene. An array of GO should be transformed according to received floats through UDP connection. I know it is simple, but can't figure it out how to accomplish the transformation an array of GO according to received unique floats for each GO, any help will be appreciated. Here is a transformation floats, it might be helpful I guess: x =ReadSingleBigEndian(data, signalOffset); signalOffset+=4; y= ReadSingleBigEndian(data, signalOffset); signalOffset+=4; z= ReadSingleBigEndian(data, signalOffset); signalOffset+=4; alpha= ReadSingleBigEndian(data, signalOffset); signalOffset+=4; theta= ReadSingleBigEndian(data,signalOffset); signalOffset+=4; phi= ReadSingleBigEndian(data,signalOffset); signalOffset+=4;

• Does semi-normalization exist as a concept? Is it "normalized"?

  - by Gracchus

  If you don't mind, a tldr on my experience: My experience tldr I have an application that's heavily dependent upon uncertainty, a bane to database design. I tried to normalize it as best as I could according to the capabilities of my database of choice, but a "simple" query took 50ms to read. Nosql appeals to me, but I can't trust myself with it, and besides, normalization has cut down my debugging time immensely over and over. Instead of 100% normalization, I made semi-redundant 1:1 tables with very wide primary keys and equivalent foreign keys. Read times dropped to a few ms, and write times barely degraded. The semi-normalized point Given this reality, that anyone who's tried to rely upon views of fully normalized data is aware of, is this concept codified? Is it as simple as having wide unique and foreign keys, or are there any hidden secrets to this technique? Or is uncertainty merely a special case that has extremely limited application and can be left on the ash heap?

• MATLAB: Best fitness vs mean fitness, initial range

  - by Sa Ta

  Based on the example of Rastrigin's function. At the plot function, if I chose 'best fitness', on the same graph 'mean fitness' will also be plotted. I understand well about 'best fitness' whereby it plots the best function value in each generation versus iteration number. It will reach value zero after some times. I don't understand about 'mean fitness'in the graph plotted. What do those 'mean fitness' values mean? How does the 'mean fitness' graph help to understand Rastrigin's function? What are the meaning of the term initial population, initial score and initial range? I wish to have a better understanding of these terms. The default value for initial range is [0,1]. Does it mean that 0 is the lower bound (lb) and 1 is the upper bound (ub)? Do these values interfere with the lb and ub values I set in the constraints? I try to better understand about lb and ub. If my lb is 0 and ub is 5, does it mean that my final point values will be within 0 and 5? If I know the lb and ub for my problem is between 0 and 5, do I just set the initial range as [0,5] at all times and may I assume that this is the best option for initial range, and I need not try it with any other values?

• OpenGL Shading Program Object Memory Requirement

  - by Hans Wurst

  gDEbugger states that OpenGL's program objects only occupy an insignificant amount of memory. How much is this actually? I don't know if the stuff I looked up in mesa is actually that I was looking for but it requires 16KB [Edit: false, confusing struct names, less than 1KB immediate, some further behind pointers] per program object. Not quite insignificant. So is it recommended to create a unique program object for each object of the scene? Or to share a single program object and set the scene's object's custom variables just before its draw call?

• The practical cost of swapping effects

  - by sebf

  I use XNA for my projects and on those forums I sometimes see references to the fact that swapping an effect for a mesh has a relatively high cost, which surprises me as I thought to swap an effect was simply a case of copying the replacement shader program to the GPU along with appropriate parameters. I wondered if someone could explain exactly what is costly about this process? And put, if possible, 'relatively' into context? For example say I wanted to use a short shader to help with picking, I would: Change the effect on every object, calculting a unique color to identify it and providing it to the shader. Draw all the objects to a render target in memory. Get the color from the target and use it to look up the selected object. What portion of the total time taken to complete that process would be spent swapping the shaders? My instincts would say that rendering the scene again, no matter how simple the shader, would be an order of magnitude slower than any other part of the process so why all the concern over effects?

• Sample size and statistical significance in Google Analytics

  - by colmcq

  I have been asked to compile a report into dropout rates during checkout for a global webstore I have used a sample size over one month as my sample because: google analytics slows to a crawl over larger sample sizes and makes much of the analysis agonisingly small I believe it to be statistically significant and a representative sample My client has asked me why I didn't use yearly figures and wants proof that one month of data is 'statistically significant'. Am I right in thinking that I need to compare the standard deviation of my monthly sample to the yearly sample and ensure that the deviation is under a certain %age? Question: how do I prove one month of Google Analytics data is representative to one year worth of data? Stats: 90k unique views/month ~1.1m per year.

• Understanding the Java Ecosystem

  - by syrion

  I have traditionally had the "luxury" of being a one-man development team. I've used Python extensively, have a reasonable command of Perl, PHP, and JavaScript. My problem is Java. I can write Java code. I'm not great at it--unlike Python, I rarely make use of anything unique to Java when I'm writing it. Furthermore, my experience is mostly in simple GUI/console programming. Unfortunately, I'm currently pursuing an IT degree where Java is the lingua franca. My database class is requiring that our projects be written in Java using servlets, and I just can't wrap my head around the ecosystem. Is there a good online overview of or tutorial on how the Java web ecosystem works? I have Thinking in Java, but it's mostly just the language itself (which I understand well enough to get by). I have looked at the Sun servlet tutorial, but it seems outdated.

• Digg alternatives for blog and unpopular users? [closed]

  - by Wladimir Ivanov

  all. I'm struggling to build an [B]audience[/B] for [B]electronic blog[/B] . The blog is relatively new and has around 30 pages. The unique visitors I get are approximately [B]120 - daily[/B]. I know about directories, rss, comments and guest blogging, but is there other more effective strategy to build some quality audience? As I see nowadays there aren't enough materials in my country about this. What about digg and reddit? Everytime I post some link there: no traffic comes to me. Can you suggest me other digg/reddit/stumbleupon tactics to get followers or there are similar sites which would tend to give me some serious traffic. Can you suggest sites appropriate for linking to music blog? Best regards.

• Google indexed my main site's content under subdomains

  - by Christie Angelwitch

  Google is indexing top level domain content as though it belongs on subdomains and I want to disable this. My site has wildcards enabled and we also have two subdomains with unique content. The first subdomain serves as a blog, the second one has only one page. Both have backlinks. Google has indexed content from the main site under the subdomains as well. Let's say that we have a page at example.com/page.html . The same page has also been indexed as subdomain.example.com/page.html as well and sometimes ranks better than the one located at the main site. The thing is that we never placed this content at the subdomain. I've thought about adding canonical tags at the subdomains to help with the duplicate content issue. How can I stop Google from indexing those pages? I don't even know how Google found those, since we never placed them at the subdomains.

• How to control an Ubuntu PC from another Ubuntu PC over Internet?

  - by Naveen

  There are two Ubuntu PCs called A and B. A and B are connected to the Internet using two separated Internet connections. (In my case, two mobile broadband connections ppp0 x2 ) Each connection has a unique & static public IP address. What I need is to control A computer's cursor, using B computer's mouse, over the Internet. In both computers, I have allowed other users to control my computer in Desktop Sharing preferences, as below: When I try to connect to A from the B using Remmina Remote Desktop Client, it refuses to connect after trying for a while. These are my settings: I expect this to be done from an available open source software, not from TeamViewer. I found this guide harder to understand. Please provide me clear instructions... Thanks for having a look!

• Do you believe it's a good idea for Software Engineers to have to work as Quality Assurance Engineers for some period of time?

  - by Macy Abbey

  I believe it is. Why? I've encountered many Software Engineers who believe they are somehow superior to QA engineers. I think it may help quench this belief if they do the job of a QA engineer for some time, and realize that it is a unique and valuable skill-set of its own. The better a Software Engineer is at testing their own programs, the less cost in time their code incurs when making its way through the rest of the software development life-cycle. The more time a Software Engineer spends thinking about how a program can break, the more often they are to consider these cases as they are developing them, thus reducing bugs in the end product. A Software Engineer's definition of "complete" is always interesting...if they have spent time as a QA engineer maybe this definition will more closely match the designer of the software's. What do you all think?

• Adding complexity by generalising: how far should you go?

  - by marcog

  Reference question: http://stackoverflow.com/questions/4303813/help-with-interview-question The above question asked to solve a problem for an NxN matrix. While there was an easy solution, I gave a more general solution to solve the more general problem for an NxM matrix. A handful of people commented that this generalisation was bad because it made the solution more complex. One such comment is voted +8. Putting aside the hard-to-explain voting effects on SO, there are two types of complexity to be considered here: Runtime complexity, i.e. how fast does the code run Code complexity, i.e. how difficult is the code to read and understand The question of runtime complexity is something that requires a better understanding of the input data today and what it might look like in the future, taking the various growth factors into account where necessary. The question of code complexity is the one I'm interested in here. By generalising the solution, we avoid having to rewrite it in the event that the constraints change. However, at the same time it can often result in complicating the code. In the reference question, the code for NxN is easy to understand for any competent programmer, but the NxM case (unless documented well) could easily confuse someone coming across the code for the first time. So, my question is this: Where should you draw the line between generalising and keeping the code easy to understand?

• Run database checks but omit large tables or filegroups - New option in Ola Hallengren's Scripts

  - by Greg Low

  One of the things I've always wanted in DBCC CHECKDB is the option to omit particular tables from the check. The situation that I often see is that companies with large databases often have only one or two very large tables. They want to run a DBCC CHECKDB on the database to check everything except those couple of tables due to time constraints. I posted a request on the Connect site about time some time ago: https://connect.microsoft.com/SQLServer/feedback/details/611164/dbcc-checkdb-omit-tables-option The workaround from the product team was that you could script out the checks that you did want to carry out, rather than omitting the ones that you didn't. I didn't overly like this as a workaround as clients often had a very large number of objects that they did want to check and only one or two that they didn't. I've always been impressed with the work that our buddy Ola Hallengren has done on his maintenance scripts. He pinged me recently about my old Connect item and said he was going to implement something similar. The good news is that it's available now. Here are some examples he provided of the newly-supported syntax: EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKDB' EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKALLOC,CHECKTABLE,CHECKCATALOG', @Objects = 'AdventureWorks.Person.Address' EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKALLOC,CHECKTABLE,CHECKCATALOG', @Objects = 'ALL_OBJECTS,-AdventureWorks.Person.Address' EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKFILEGROUP,CHECKCATALOG', @FileGroups = 'AdventureWorks.PRIMARY' EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKFILEGROUP,CHECKCATALOG', @FileGroups = 'ALL_FILEGROUPS,-AdventureWorks.PRIMARY' Note the syntax to omit an object from the list of objects and the option to omit one filegroup. Nice! Thanks Ola! You'll find details here: http://ola.hallengren.com/

• Do we have enough time to build an electric car future?

  - by julien.groues

  A recent article from Greenbang has posed the question 'Do we have enough time to build an electric car future?'. The writer discusses that, although the future of transport might lie with electric cars, there is concern regarding whether we'll be able to build the market and infrastructure required to support them, before carbon and oil constraints create difficulties in powering the vehicles. Of course, the increasing use of Electric vehicles (EVs) is going to put excessive pressure on energy grids, as large volumes of electricity will need to be directed to charging points, which in turn must handle fluctuating demand at peak times. EVs are increasing in popularity as a sustainable method of transport to reduce carbon consumption, and electric utilities will have the opportunity, and the challenge, to quickly determine the best methods to fuel these vehicles and accommodate the associated increases in demand for energy. Critically, efficient software is required to provide diagnostic and predictive capabilities related to EV refuelling - for example, anticipated electricity flow will need to be addressed as the number of EVs on the road increases, and electricity will need to be directed to specific areas on-demand as vehicles attempt to recharge en-mass. But a smart grid infrastructure can meet these demands, intelligently. The implementation of a smart grid is not in the distant future, it is an achievable reality for utilities via simple installation of new software and technologies, which can be done incrementally for those facing existing legacy systems or concerned with upfront costs. The smart grid is integral to the monitoring and control of energy use as well as the future-proofing of the energy grid. A smart grid will be critical to meeting the electricity requirements of new EVs and will ensure their successful deployment by providing a reliable foundation for the data handling required to record and manage electricity distribution - from recording and assessing energy usage, to analysing data and sharing information with consumers via green billing. http://www.greenbang.com/do-we-have-enough-time-to-build-an-electric-car-future_14248.html
