• why no += operator for vectors in stl

  - by Akshay Bhat

  I am curious? What high fundu logic goes behind not implementing: result+=vector1; where both result and vector1 are stl vectors. Note: i know how to implement that bit, but i need to know what logic, the sages who designed STL were using when they chose not to implement this feature?

• Effect of suffixes in memory to cache operations

  - by tur1ng

  In x86 GNU Assembler there are different suffixes for memory related operations. E.g.: movb, movs, movw, movl, movq, movt(?) Now my question is the following: Does the suffix has ANY effect on how the processor is getting the data out of main memory or will always be one or more 32-bit (x86) chunks loaded into the cache ? What are the effects beside the memory access?

• how to search "n bits" in a byte array?

  - by ZhengZhiren

  i have a byte array. Now i need to know the count of appearances of a bit pattern which length is N. For example, my byte array is "00100100 10010010" and the pattern is "001". here N=3, and the count is 5. Dealing with bits is always my weak side.

• Ruby equivalent to "grep -C 5" to get context of lines around the match?

  - by wonderfulthunk

  I've searched for this a bit but I must be using the wrong terms - does ruby have a way to grep for a string/regex and also return the surrounding 5 lines (above and below)? I know I could just call "grep -C 5 ..."or even write my own method, but it seems like something ruby would have and I'm just not using the right search terms.

• Convert an array of primitive longs into a List of Longs

  - by CaptainAwesomePants

  This may be a bit of an easy, headesk sort of question, but my first attempt surprisingly completely failed to work. I wanted to take an array of primitive longs and turn it into a list, which I attempted to do like this: long[] input = someAPI.getSomeLongs(); List<Long> = Arrays.asList(input); //Total failure to even compile! What's the right way to do this?

• Strategy for wiring up events?

  - by Jeffrey Cameron

  I'm using Ninject (1.5 ... soon to be 2) and I'm curious how other people use Ninject or other IoC containers to help wire up events to objects? It seems to me in my code that I'm doing it herky-jerky all over the place and would love some advice on how to clean it up a bit. What are people doing out there to manage this?

• browser instant updates with ajax/jquery

  - by wcpro

  I'm trying to reverse engineer how facebook handles their notifications, where when you get a message you get instantly notified via the browser. I've fiddled with it for a little bit and realized that there is always a pending GET request "listening" if you will to some sort of update from the server. This appears to be some sort of observer pattern. I was just wondering if this pattern was documented somewhere.

• CursorLoader, get URI for local database

  - by user1681358

  I'm a newbie android programmer and I recently followed a tutorial which shows how to create a local SQLite database by using SQLiteDatabase.rawQuery to return a Cursor. I would like to modify my app to use CursorLoader which is apparently a better way to access the database. My problem is the CursorLoader constructor expects a URI to be given. Do I just input "file:///[path to db]"? Seems a bit messy.

• Copying from istream never stops

  - by the_drow

  This bit of code runs infinitely: copy(istream_iterator<char>(cin), istream_iterator<char>(), back_inserter(buff)); The behavior I was expecting is that it will stop when I press enter. However it doesn't. buff is a vector of chars.

• Hidden features of mod_rewrite

  - by Owen

  There seem to be a decent number of mod_rewrite threads floating around lately with a bit of confusion over how certain aspects of it work. As a result I've compiled a few notes on common functionality, and perhaps a few annoying nuances. What other features / common issues have you run across using mod_rewrite?

• Basic question about encryption - what exactly are keys?

  - by Tomas

  Hi, I was browsing and found good articles about encryption. However, none of them described why the key lenght is important and what exactly the key is used for. My guess is that could work this way: 0101001101010101010 Key: 01010010101010010101 //the longer the key, the longer unique sequence XOR or smth: //result Is this at least a bit how it works or I am missing something? Thanks

• c# 3.5 class List<int> class initialisation

  - by josephj1989

  I can initialize a List like new List{1,2,3,4,5}; However List does not have a constructor which accepts a single parameter. So I tried to run this through the debugger and it seems to be calling the Add method. So how does the compiler know which method to invoke to add each individual element. This may be a silly question but I am a bit confused. Thanks

• Why is cakephp form input stored in $this->data and POST data stored in $this->params['form'] ?

  - by spudnik1979

  the cakephp rest tutorial says that post data should be in $this-data, but I am finding that it is not, but instead inside $this-params['form'] However, when using cakephp form helper in a view, the data is in $this-data. Am I correct to have to check both locations in my controller? It just seems a bit of a waste of extra code. Shouldnt the data appear in one place for whether it came from a rest rest requestor or Cakephp form post? ps im using cakephp 1.3

  Hi, I love my Mac. But I have always found that my DNS lookups are as slow, even while flushing caches and I travel over know roads on the Internet.
