• Features to remove from C++

  - by Justin Ethier

  This question was inspired by What features would you like to see added to C++? (also see What features do you miss in C++?). C++ is a great general-purpose language, but perhaps too general and feature-rich: multiple inheritance, operator overloading, manual memory management, templates, smart pointers, virtual destructors, legacy frameworks (think MFC), and I could go on. Is there any one feature or aspect of C++ that you would like removed to make our lives easier as C++ developers? One feature per answer, please.

• Using Entity Framework V4 - Mapping Stored Procedures with XML output

  - by ericwahner

  I have been attempting to implement the Entity framework into my project and unfortunately it seems like mapping an XML result set from SQL is not something that is supported. I also have issues with returning multiple result sets, though I understand that the EFExtensions was created to try to mitigate that issue. Is there a way to take a FOR XML EXPLICIT result from a SQL Stored Procedure and map it using the Entity Framework?

• Is foreach statement iterate in order or it might be random order?

  - by ablimit

  I was wondering if the foreach statement in perl iterates the items in an array in consistent order ? That is, do I get different results if I use foreach multiple times on the same array or list ? Thanks.

• Memcached for PHP 5.3

  - by Industrial

  Hi everyone, I have looked everywhere for some clues on how to run the Memcached extension in my WAMP windows development environment (thats right, the memcached with an D in the end, not memcache). I already use memcache (without the D), but it would be handy to take part of memcached's more extended multiple-server features. How can I get this up and running? Thanks

• Design and Implementation stories for one feature in SCRUM?

  - by finrod

  If I divide development of a particular feature into multiple stories: First one for a high level design of the feature, Based on first story I create other stories to develop the different stand-alone pieces that compose the feature, Does it mean I'm doing waterfall?

• How do I declare a constructor for an 'object' class type in Scala? I.e., a one time operation for the singleton.

  - by Zack

  I know that objects are treated pretty much like singletons in scala. However, I have been unable to find an elegant way to specify default behavior on initial instantiation. I can accomplish this by just putting code into the body of the object declaration but this seems overly hacky. Using an apply doesn't really work because it can be called multiple times and doesn't really make sense for this use case. Any ideas on how to do this?

• How can I automate updating my SQL Server database?

  - by Sanju

  I get multiple text files daily to update my database from my client side and I am not a DBA expert. Every day I update it manually. Is there any method I can use to make this easier? I think there is a way to automate it but I don't know exactly what to do.

• MySQL - Limit a left join to the first date-time that occurs?

  - by John M

  Simplified table structure (the tables can't be merged at this time): TableA: dts_received (datetime) dts_completed (datetime) task_a (varchar) TableB: dts_started (datetime) task_b (varchar) What I would like to do is determine how long a task took to complete. The join parameter would be something like ON task_a = task_b AND dts_completed < dts_started The issue is that there may be multiple date-times that occur after the dts_completed. How do I create a join that only returns the first tableB-datetime that occurs after the tableA-datetime?

• How are Cassandra's 0.7 Secondary Indexes stored?

  - by user574793

  We have been using Cassandra 0.6 and now have Column Families with millions of keys. We are interested in using the new Secondary Index feature available in the 0.7 but couldn't find any documentation on how the new index is stored. Is there any disk-space limitation or is the index stored similar to keys in that it's spread over multiple nodes? I've tried combing through the Cassandra site for an answer but to no avail.

  - by kunjaan

  Why doesn't the compiler automatically put break statements after each code block in the switch? Is it for historical reasons? When would you want multiple code blocks to execute?

• What work has been done on cross-platform mobile development?

  - by Nicholas

  Have any well-documented or open source projects targeted iPhone, Blackberry, and Android? Are there other platforms which are better-suited to such an endeavor? Note that I am particularly asking about client-side software, not web apps, though any information about the difficulties of using web apps across multiple mobile platforms is also interesting.

• Play an AudioBufferSourceNode twice?

  - by alltom

  Should I be able to use the same AudioBufferSourceNode to play a sound multiple times? For some reason, calling noteGrainOn a second time doesn't play audio, even with an intervening noteOff. This code only plays the sound once: var node = audioContext.createBufferSource() node.buffer = audioBuffer node.connect(audioContext.destination) var now = audioContext.currentTime node.noteGrainOn(now, 0, 2) node.noteOff(now + 2) node.noteGrainOn(now + 3, 0, 2) node.noteOff(now + 5)

• URL structure preference - to slash or not to slash?

  - by TheDeadMedic

  I'm using custom post types in WordPress 3.0 to manage 'courses' (or seminars, lectures, whatever term you'd prefer to have in mind). Now for viewing a single 'course', the url structure is; /course/course-name/ But for multiple courses? /courses/category/category-name/ Or... /course-category/category-name/ Or something entirely different?

• JIRA or Trac?

  - by seedhead

  I used Atlassian JIRA for bug and issue tracking at my last job. I absolutely loved it and it was particularly easy on the eyes. My present company is using Trac instead, and while it does do all the basics, I am finding it really lacking, particularly with the inability to easily setup multiple projects and link issues. Oh, and the fact that it uses SQLLite is a bit of an issue for me to. Does anyone have any other good reasons to switch?

• Another Memory Alignment Question?

  - by utxeeeee

  I understand why data need to be aligned (and all the efforts made to accomplish it like padding) so we can reduce the number of memory accesses but this assumes that processor just can fetch addresses multiples of 4(supposing we are using a 32-bit architecture). And because of that assumption we need to align memory and my question is why we can just access addresses multiple of 4(efficiency, hardware restriction, another one)? Which is the advantages of doing this? Why cannot we access all the addresses available? hugs

• Pie chart of *nix shell use [closed]

  - by hayk.mart

  I've encountered a situation where it would be very helpful to know the breakdown of shell use by percentage. For example, I'm looking for something like bash: X%, sh: Y%, csh, tcsh, zsh, ksh, dash, etc.. Obviously, I know there are several complications - multiple shells, the definition of "use", uncertainty and so forth, but I would like to see an informed answer derived from actual data and based on some stated metric, even if the result could be horribly wrong. Bonus if there is historical data demonstrating a shift in preferences.
