• Business Units vs Teams in CRM 2011

  - by GuruJ

  I've been told a few times that Business Units in CRM 2011 are "tricky" and shouldn't be set up lightly since they have irreversible consequences for a CRM 2011 implementation. On the other hand, teams in CRM 2011 seem much more flexible in managing record security. For what reason would I still choose to set up Business Units in CRM 2011? What can I do with Business Units that I can't with Teams (and vice versa)?

• which loop is faster?

  - by Mansuro

  I have this loop for (it= someCollection.iterator; it.hasNext(); ) { //some code here } I changed it to: for (it= someCollection.iterator;; ) { if (!it.hasNext()) break; //some code here } The second code ran a little bit faster in unit tests in junit on eclipse. Is the second loop faster? I'm asking because the times given by Junit are not too exact, but they give an approximate value

• Is there a way I can overlay graphics on top of all windows using C#?

  - by Secrest

  I want to create a C# app which rests in the system tray. However, I would like this application to overlay certain graphic elements / drawing on top of the screen above all windows at certain times. So, for example, while my application is running, even though minimized to the tray, it will draw certain shapes on top of the screen regardless of what is there. Is this possible using C#? If not, is there any other language that would have this capability?

• Optimizing division/exponential calculation

  - by Saltheart

  I've inherited a Visual Studio/VB.Net numerical simulation project that has a likely inefficient calculation. Profiling indicates that the function is called a lot (1 million times plus) and spends about 50% of the overall calculation within this function. Here is the problematic portion Result = (A * (E ^ C)) / (D ^ C * B) (where A-C are local double variables and D & E global double variables) Result is then compared to a threshold which might have additional improvements as well, but I'll leave them another day any thoughts or help would be appreciated Steve

  Is there any efficient way in python to count the times an array of numbers is between certain intervals? the number of intervals i will be using may get quite large like: mylist = [4,4,1,18,2,15,6,14,2,16,2,17,12,3,12,4,15,5,17] some function(mylist, startpoints): # startpoints = [0,10,20] count values in range [0,9] count values in range [10-19] output = [9,10]

  I do not understand what is meant by the terms "compile time" and "run time" (or "runtime"). I'm also a bit confused about what "value type" and "reference type" mean, and how they relate to the 'times mentioned above. Would someone please explain these things?

• PHP array performance

  - by dfo

  Hi, this is my first question on Stackoverflow, please bear with me. I'm testing an algorithm for 2d bin packing and I've chosen PHP to mock it up as it's my bread-and-butter language nowadays. As you can see on http://themworks.com/pack_v0.2/oopack.php?ol=1 it works pretty well, but you need to wait around 10-20 seconds for 100 rectangles to pack. For some hard to handle sets it would hit the php's 30s runtime limit. I did some profiling and it shows that most of the time my script goes through different parts of a small 2d array with 0's and 1's in it. It either checks if certain cell equals to 0/1 or sets it to 0/1. It can do such operations million times and each times it takes few microseconds. I guess I could use an array of booleans in a statically typed language and things would be faster. Or even make an array of 1 bit values. I'm thinking of converting the whole thing to some compiled language. Is PHP just not good for it? If I do need to convert it to let's say C++, how good are the automatic converters? My script is just a lot of for loops with basic arrays and objects manipulations. Thank you! Edit. This function gets called more than any other. It reads few properties of a very simple object, and goes through a very small part of a smallish array to check if there's any element not equal to 0. function fits($bin, $file, $x, $y) { $flag = true; $xw = $x + $file->get_width();; $yh = $y + $file->get_height(); for ($i = $x; $i < $xw; $i++) { for ($j = $y; $j < $yh; $j++) { if ($bin[$i][$j] !== 0) { $flag = false; break; } } if (!$flag) break; } return $flag; }

• Limit exceeded on sitemap submission to Yahoo.

  - by user173457

  I'm getting an error saying, "Limit exceeded" when I am submitting my sitemap to Yahoo. Can anyone explain what the error means? Possible problems: 1. Too many submissions: we certainly don't send the sitemap 5000 times in a day. 2. The sitemap is too big: Our sitemap is a mere 40k file and gzipped. Thanks.

• How can I get weighted random selections from an array in Perl?

  - by Chaggster

  I need to random some elements from an array. I'm doing that by randomizing the index $array[int(rand(100))]. I want some of the elements to appear more often. How do I do it? I thought of a stupid solution of having those elements duplicated several times in the array, but I'm sure you guys can do better.

• Nhiberate, multiple tables, same class

  - by jeff

  It's been asked a million times, its like this. Say Invoice is the base class and InvoiceHistory is the class that simply inherits from Invoice. When I do something like invoiceList = session.CreateCriteria(typeof(Invoice)).List(); I get everything from Invoice (that I want, plus everything from InvoiceHistory). Do I need to have an InvoiceBase and create derived versions for Invoice and InvoiceHistory?

• How to discover what Linux distro is in use

  - by Seiti

  Sometimes I need to access some servers running Linux (or maybe another Unix-like SO), but I don't know how to verify which distro is in use on the server (there are times that even the "responsible" for the server doesn't know). Is there a easy and reliable way to discover that, one that is uniform and consistent across all of them?
