• Script tag in XHTML

  - by Ben

  Hi, This might sound like a reaaaally dumb question but... why do browsers have a fit with this syntax: <script type='text/javascript' src="/path/to/my.js" /> and want this instead <script type='text/javascript' src="/path/to/my.js"></script> Seems the first construct should be valid since there's no inner content to the tag.. ?

• Widgets and .mobi sites, is this possible?

  - by Roland

  I have a couple of concerns, I'm busy building a normal .mobi site for a client, so basically how I understand this is keep it simply since most phones do not support JavaScript and have a small screen etc. So I build a mobi site using only content and basic links. Now my question is how do mobi widgets work on a mobile site? I've googled and could not find a answer? Is this possible at all?

• Can we use JCR API over MySQL?

  - by n_mysql

  Apache Jackrabbit (or the JCR API) helps you separate the data store from the data management system. This would mean that every data store provider would have to implement the JCR API for his own data store. The question is JCR implemented for MySQL? Can we use the JCR API over MySQL? I want to truly abstract out where i store my content, so that tomorrow if i don't want to use a relational DB i can swap it out with the file system with ease.

• Differnce between linux write and sendfile syscall

  - by JosiP

  Hi Im programming webserver (C), which should send big files. My question is: What are the main differneces in two syscalls: write and sendfile. Does sendfile depends on size of socket system buffer ? I noticed that write often writes less then i requested. For example, if got many requests for one file: should i open it, copy into memory and use 'write', or maybe i can do 'sendfile' for each client ? thx in advance for all answers

• Can a stack have an exception safe method for returning and removing the top element with move seman

  - by Motti

  In an answer to a question about std::stack::pop() I claimed that the reason pop does not return the value is for exception safety reason (what happens if the copy constructor throws). @Konrad commented that now with move semantics this is no longer relevant. Is this true? AFAIK, move constructors can throw, but perhaps with noexcept it can still be achieved. For bonus points what thread safety guarantees can this operation supply?

• Any example on how to implement the new VerificationController and the KNOWN_TRANSACTIONS_KEY constant?

  - by Carles Estevadeordal

  I've been looking at implementing the new VerificationController to verify in-App-Purchases: http://developer.apple.com/library/ios/#releasenotes/StoreKit/IAP_ReceiptValidation/_index.html And I wonder if there is some example anywhere en how to validate a transaction, since it seems that the - (BOOL)verifyPurchase:(SKPaymentTransaction *)transaction; is not enough and it has to be implemented internally to verify the purchase when the data form the server is received. Another question is if anyone has a clue on what the KNOWN_TRANSACTIONS_KEY is and how to fill it, is it just the product id of the purchase?

• To HTML 5 or not HTML 5 ?

  - by ZX12R

  I am a designer whose main marketing strategy is multi browser compatibility. I assure my clients that the site will work even in IE6 (!).

Is there any way of moving to HTML 5 and still promise multi browser compatibility? Thank you.

• VBScript file open dialog that works in XP and Vista?

  - by codeulike

  In XP, you can use VBScript with the UserAccounts.CommonDialog object to bring up a File Open dialog (as described here), but apparently this does not work under Vista. Is there a VBScript method for File-Open dialogs that will work for both? Or even one that will work nicely for Vista? Disclaimer: I'm a proper programmer, honest, and don't usually work with VBScript - I am asking this question 'for a friend'.

• Idea for a user friendly/non technical RAD tool for performing queries and reports on Database

  - by pierocampanelli

  I am investigating for a tool that allows a user to perform in a user friendly way queries to database for extracting datas and creating reports. Primary requirement is that we can't know queries users are going to do. So we need to design a flexible UI allowing them to specify in a non technical way. My question is: do you know any tool that does something similar? Have you some inspiring user interface?

• When to address integer overflow in C

  - by Yktula

  Related question: http://stackoverflow.com/questions/199333/best-way-to-detect-integer-overflow-in-c-c In C code, should integer overflow be addressed whenever integers are added? It seems like pointers and array indexes should be checked at all. When should integer overflow be checked for? When numbers are added in C without type explicitly mentioned, or printed with printf, when will overflow occur? Is there a way to automatically detect when an integer arithmetic overflow?
