• What server log file(with Centos5) must I check to locate specific IP activity?

  - by makmour

  Hi! I leasing a dedi server under Centos5, just recently I ve setup a blog website that grabs feeds from other news websites and presents them on my blog. Some days after I see high server loads that cant be coming just from the cron jobs that I run every now and then to grab feeds from other websites for my blog website. Thats why I m trying to pico some log files in order to have a better look the whole problem. These last days I noticed(from statscounter service) the same IP address visiting my blog website many times per day so I want to find out what us trying to do. I tried looking in all /var/log log files and httpd too but no luck. Is there any other log file I should open or any other procedure to track this IP acivity on server?

• Divide and Conquer Algo to find maximum difference between two ordered elements

  - by instance

  Given an array arr[] of integers, find out the difference between any two elements such that larger element appears after the smaller number in arr[]. Examples: If array is [2, 3, 10, 6, 4, 8, 1, 7] then returned value should be 8 (Diff between 10 and 2). If array is [ 7, 9, 5, 6, 3, 2 ] then returned value should be 2 (Diff between 7 and 9) My Algorithm: I thought of using D&C algorithm. Explanation 2, 3, 10, 6, 4, 8, 1, 7 then 2,3,10,6 and 4,8,1,7 then 2,3 and 10,6 and 4,8 and 1,7 then 2 and 3 10 and 6 4 and 8 1 and 7 Here as these elements will remain in same order, i will get the maximum difference, here it's 6. Now i will move back to merege these arrays and again find the difference between minimum of first block and maximum of second block and keep doing this till end. I am not able to implement this in my code. can anyone please provide a pseudo code for this?

• introduce a join to this query, possible?

  - by Iain Urquhart

  I'm trying to introduce a join to this query: SELECT `n`.*, round((`n`.`rgt` - `n`.`lft` - 1) / 2, 0) AS childs, count(*) - 1 + (`n`.`lft` > 1) + 1 AS level, ((min(`p`.`rgt`) - `n`.`rgt` - (`n`.`lft` > 1)) / 2) > 0 AS lower, (((`n`.`lft` - max(`p`.`lft`) > 1))) AS upper FROM `exp_node_tree_6` `n`, `exp_node_tree_6` `p`, `exp_node_tree_6` WHERE `n`.`lft` BETWEEN `p`.`lft` AND `p`.`rgt` AND ( `p`.`node_id` != `n`.`node_id` OR `n`.`lft` = 1 ) GROUP BY `n`.`node_id` ORDER BY `n`.`lft` by adding LEFT JOIN `exp_channel_titles` ON (`n`.`entry_id`=`exp_channel_titles`.`entry_id`) after the FROM statement... But when I introduce it, it fails with "Unknown column 'n.entry_id' in 'on clause'" Is it even possible to add a join to this query? Can anybody help, thanks!

• Scala downwards or decreasing for loop?

  - by Felix

  In scala, you often use an iterator to do a for loop in an increasing order like: for(i <- 1 to 10){ code } How would you do it so it goes from 10 to 1? I guess 10 to 1 gives an empty iterator (like usual range mathematics)? I made a scala script which solves it by calling reverse on the iterator, but it's not nice in my opinion, is this the way to go: def nBeers(n:Int) = n match { case 0 => ("No more bottles of beer on the wall, no more bottles of beer."+ "\nGo to the store and buy some more, "+ "99 bottles of beer on the wall.\n") case _ => (n+" bottles of beer on the wall, "+n +" bottles of beer.\n"+"Take one down and pass it around, "+ (if((n-1)==0) "no more" else (n-1))+ " bottles of beer on the wall.\n") } for(b <- (0 to 99).reverse)println(nBeers(b)) ?? Any comments/suggestions?

• Linq: How to calculate the sales Total price and group them by product

  - by Daoming Yang

  I have a order list and I want to generate and rank the product with its total sales and quantity. With @tvanfosson's help, I can bring the grouped product detail with the following code, but how can I calculate and add up the total sales and quantity into each productListResult's object? Can anyone help me with this? Many thanks. var orderProductVariantListResult = productList.SelectMany(o => o.OrderProductVariantList) .Select(opv => new { Product = opv.ProductVariant.Product, Quantity = opv.Quantity, PriceSales = opv.PriceSales, Sales = opv.Quantity * opv.PriceSales, }); var productListResult = orderProductVariantResult .Select(pv => pv.Product) .GroupBy(p => p) .Select(g => new { Product = g.Key, TotalOrderCount = g.Count() }) .OrderByDescending(x => x.TotalOrderCount).ToList();

• Achieving AES-256 Channel Encryption with the .NET Compact Framework

  - by Ev

  Hi There, I am working on a business application where the clients are Windows Mobile 6.1 Professional devices. The server is a Java enterprise application. The industry working group recommends AES-256 encryption for client/server communications. This is necessary to gain certification. The encryption doesn't necessarily need to be channel encryption, it could be payload encryption. Channel encryption is preferable. The client and server communicate using SOAP/HTTP, which we are yet to implement. We plan to use WCF on the compact framework. In order to alleviate some of the work required to implement manual encryption/decryption, it would be nice if we could achieve the required encryption either at the TLS level, or somehow using the WS-* standards (I'm not particularly familiar with that group of technologies but I am learning right now). The server supports https with 256-bit AES. Does anybody have an idea on the best way to implement this? Thanks in advance.

• Rails 4 json return on API

  - by El - Key

  I'm creating an API on my application. I currently overrided the as_json method in my model in order to be able to get attached files as well as logo from Paperclip : def as_json( options = {} ) super.merge(logo_small: self.logo.url(:small), logo_large: self.logo.url(:large), taxe: self.taxe, attachments: self.attachments) end Then within my controller, I'm doing : def index @products = current_user.products respond_with @products end def show respond_with @product end The problem is that on the index, I don't want get all the attachments. I only need it on the show method. So I tried it : def index @products = current_user.products respond_with @products, except: [:attachments] end But unfortunately it's not working. How can I do to not send :attachments? Thanks

• Stable separation for two classes of elements in an array

  - by AndreyT

  Consider the following problem. We are given an array of elements belonging to one two classes: either red or blue. We have to rearrange the elements of the array so that all blue elements come first (and all red elements follow). The rearrangement must be done is stable fashion, meaning that the relative order of blue elements must be preserved (same for red ones). Is there a clever algorithm that would perform the above rearrangement in-place? A non-in place solution is, of course, straightforward. An obvious in-place solution would be to apply any stable sorting algorithm to the array. However, using a full-fledged sorting algorithm on an array intuitively feels like an overkill, especially taking into account the fact that we are only dealing with two classes of elements. Any ideas greatly appreciated.

• What are some useful SQL statements / usage patterns that should be known by all developers who may

  - by Jian Lin

  What are some useful SQL statements that should be known by all developers who may touch the Back end side of the project? (Update: just like in algorithm, we know there are sorting problems, shuffling problems, and we know some solutions to them. This question is aiming at the same thing). For example, ones I can think of are: Get a list of Employees and their boss. Or one with the employee's salary greater than the boss. (Self-join) Get a list of the most popular Classes registered by students, from the greatest number to the smallest. (Count, group by, order by) Get a list of Classes that are not registered by any students. (Outer join and check whether the match is NULL, or by Get from Classes table, all ClassIDs which are NOT IN (a subquery to get all ClassIDs from the Registrations table)) Are there some SQL statements that should be under the sleeve of all developers that might touch back end data?

• How do I add a VSTO project as a reference to a unit testing project?

  - by Mathias

  In order not to pollute my projects with unit tests, I like to create a separate project for my unit tests; I add a reference to the project under test in the unit tests project. However, this isn't working that well with my VSTO excel add-in projects: when I create a separate unit test project and go to Add Reference Projects, there is no project to pick. What I have done so far is Add Reference Browse, and pick the add-in dll from the debug folder. I have also run into issues from time to time with this, with the reference suddenly not working, requiring to remove/re-add the dll reference. Can anybody explain why a VSTO project doesn't show up as a regular project? And is there a better way to go about it than what I am doing presently?

• Block all other input to an application and control it from a wrapper in Java

  - by Oren

  I have a windows application which has a complex GUI that I would like to hide from users. In order to do this, I would like to create a wrapper with an extremely simple interface that overlays this application and automates a number of actions when a user clicks a single button on the wrapper. (I hope "wrapper" is the proper term.) Is it possible to use Java to block input to the underlying application so that users cannot inadvertently mess up the automation? How would I go about this? Also, how can I automate key presses and clicks to the application without hijacking the mouse? Is this possible in Java? I have looked at java.awt.Robot, but it appears to hijack the mouse. I have also looked at AutoIT, but it too hijacks the mouse and does not integrate with Java. Neither of these options seem powerful enough for what I need, but I do not know how else to proceed.

• How can I maximally partition a set?

  - by Gregory Higley

  I'm trying to solve one of the Project Euler problems. As a consequence, I need an algorithm that will help me find all possible partitions of a set, in any order. For instance, given the set 2 3 3 5: 2 | 3 3 5 2 | 3 | 3 5 2 | 3 3 | 5 2 | 3 | 3 | 5 2 5 | 3 3 and so on. Pretty much every possible combination of the members of the set. I've searched the net of course, but haven't found much that's directly useful to me, since I speak programmer-ese not advanced-math-ese. Can anyone help me out with this? I can read pretty much any programming language, from BASIC to Haskell, so post in whatever language you wish.

• Delphi Search files and directories fastest alghorithm

  - by radu-barbu

  Hi, I'm using Delphi7 and i need a solution to a big problem.Can someone provide me a faster way for searching through files and folders than using findnext and findfirst? because i also process the data for each file/folder (creation date/author/size/etc) and it takes a lot of time...I've searched a lot under WinApi but probably I haven't see the best function in order to accomplish this. All the examples which I've found made in Delphi are using findfirst and findnext... Also, I don't want to buy components or use some free ones... Thanks in advance!

• Side effects of reordering columns in PostgreSQL

  - by Summer

  I sometimes re-order the columns in my Postgres DB. Since Postgres can only add columns at the end of tables, I end up re-ordering by adding new columns at the end of the table, setting them equal to existing columns, and then dropping the original columns. My question is: what does PostgreSQL do with the memory that's freed by dropped columns? Does it automatically re-use the memory, so a single record consumes the same amount of space as it did beforehand? But that would require a re-write of the whole table, so to avoid that, does it just keep a bunch of blank space around in each record? Thanks! ~S

• Organizing a random list of objects in Python.

  - by Saebin

  So I have a list that I want to convert to a list that contains a list for each group of objects. ie ['objA.attr1', 'objC', 'objA.attr55', 'objB.attr4'] would return [['objA.attr1', 'objA.attr55'], ['objC'], ['objB.attr4']] currently this is what I use: givenList = ['a.attr1', 'b', 'a.attr55', 'c.attr4'] trgList = [] objNames = [] for val in givenList: obj = val.split('.')[0] if obj in objNames: id = objNames.index(obj) trgList[id].append(val) else: objNames.append(obj) trgList.append([val]) #print trgList It seems to run a decent speed when the original list has around 100,000 ids... but I am curious if there is a better way to do this. Order of the objects or attributes does not matter. Any ideas?

• SQL help - find the table that has 'somefieldId' as the primary key?

  - by Kettenbach

  Hello All, How can I search my sql database for a table that contains a field 'tiEntityId'. This field is referenced in a stored procedure, but I am unable to identify which table this id is a primary key for? Any suggestions? I currently look through stored procedure definitions for references to text by using something like this Declare @Search varchar(255) SET @Search='[10.10.100.50]' SELECT DISTINCT o.name AS Object_Name,o.type_desc FROM sys.sql_modules m INNER JOIN sys.objects o ON m.object_id=o.object_id WHERE m.definition Like '%'+@Search+'%' ORDER BY 2,1 Any SQL guru's out there know what I need to use to find the table that contains the field, 'preferably the table where that field is the Primary Key. Thanks so much for any tips. Cheers, ~ck in San Diego

• How to enable/create elements on the fly

  - by Simon S

  Hi all I am using a combination of PHP, jQuery and Spry to serve a series of listboxes in which a user will select first the type of vehicle, then the make, then the model and finally the specific model. All my listboxes (SELECT) are working fine, and they update properly using the Spry elements. Each listbox is populated from a different Spry XML Dataset, and this is my problem. If I present all four listboxes to the user, the script has to go and fetch all four lots of XML to populate all four listboxes, taking several seconds. What I want to do is to create/enable the listboxes in order, so at the user selects from the first listbox, the second is created/enabled, when they select from the second, the third is created/enabled... and so on. Setting the disabled attribute is no good because the script has already fetched the XML before this is processed. Any ideas?? Si

• jQuery all inputs with unique id

  - by d3020

  I have some textboxes on a webform that have ids like this: txtFinalDeadline_1 txtFinalDeadline_2 txtFinalDeadline_3 txtFinalDeadline_4 In my jQuery how do I find all of those in order to assign a value to them. Before I had the underscore and they were all named txtFinalDeadline I could do this and it worked. $(this).find("#txtFinalDeadline").val(formatDate); However, that was when they were all named the same thing. Now I have the _x after the name and I'm not sure how to go about assigning that same value as before to them. Thanks.

• Gluing tiles together using imagemagick's montage command

  - by AP257

  This seems like it might be a reasonably common question, so I'm going to ask it using as many keywords as I can think of! I have a bunch of (well, nine) tile jpegs, with standard tile filenames. Each jpeg is 220x175 pixels: (top row) tile_1_0_0.jpg tile_1_1_0.jpg tile_1_2_0.jpg (middle row) tile_1_0_1.jpg tile_1_1_1.jpg tile_1_2_1.jpg (bottom row) tile_1_0_2.jpg tile_1_1_2.jpg tile_1_2_2.jpg How can I use imagemagick/montage to 'glue' or join them all together to make a single, coherent image? I don't want to resize them at all, so I guess the final image should be 660x525. That would be montage with no framing, shadowing, bordering, etc - just the nine original images, glued together to make a single jpeg. I know it should be something along these lines, but I'm struggling with getting the order and sizing right: montage +frame +shadow +label -tile 3x3 -geometry <options> *.jpg joined.jpg
