• Recommend a local LDAP store for development

  - by Paul Stovell

  Our project uses an LDAP repository for storing users. In production this will be Active Directory. For development, we seem to have a couple of options: Install an AD LDS instance that everyone uses Install an AD LDS instance on every developer machine We're trying to keep the 'F5' experience as lightweight as possible, so installing things or relying on a central AD store aren't my favorite ideas. There are other LDAP servers, like Open LDAP. I was hoping there might be an LDAP server that simply talks to an XML file. This would allow us to store the XML file in source control and have something that is fast and works. Our nightly builds would still use AD to pick up any differences, but the hope is since we're using LDAP it should Just Work. Can you recommend an LDAP implementation that works well for zero-config shared-nothing development?

• problem with update the counter value

  - by Edan

  Hello, I having problem to update the counter (integer value). this is the definitions of the class: public class Item_Actions { private final int MAX_ITEMS = 100; private Item myItem[]; private int counter; public Item_Actions() { myItem = new Item[MAX_ITEMS]; counter++; } //Constructor add item into the menu (Description, type & price of Item) public void addItem(Item itm) { myItem[counter] = itm; counter++; }....... Now everytime I call the addItem constructor from another class, the counter always stays on zero. What causing it and how do I save the data inside? thanks

• Masking a bit in C returning unexpected result

  - by Eamorr

  0x7F000000 is 0111 1111 0000 0000 0000 0000 0000 0000 in 32 bit binary. 0x01000058 is 0000 0001 0000 0000 0000 0000 0101 1000. When I AND the two numbers together I expect 0000 0001 0000 0000 0000 0000 0000 0000, but for some reason I get 0. Here is my code: #define MASK_binop 0x80000000 #define MASK_operation 0x7F000000 int instruction=atoi(line); if((MASK_binop & instruction)>0) printf("binop\n"); else if((MASK_operation & instruction)>0) printf("operation\n"); Each of the above comparisons keeps returning zero. Is it something to do with 32/64 bits? I'm using 64-bit compiler.

• Initialising structs in C++

  - by Neil Butterworth

  As an addendum to this question, what is going on here: #include <string> using namespace std; struct A { string s; }; int main() { A a = {0}; } Obviously, you can't set a std::string to zero. Can someone provide an explanation (backed with references to the C++ Standard, please) about what is actually supposed to happen here? And then explain for example): int main() { A a = {42}; } Are either of these well-defined? Once again an embarrassing question for me - I always give my structs constructors, so the issue has never arisen before.

• Lazy sequence or recur for mathematical power function?

  - by StackedCrooked

  As an exercise I implemented the mathematical power function. Once using recur: (defn power [a n] (let [multiply (fn [x factor i] (if (zero? i) x (recur (* x factor) factor (dec i))))] (multiply a a (dec n)))) And once with lazy-seq: (defn power [a n] (letfn [(multiply [a factor] (lazy-seq (cons a (multiply (* a factor) factor))))] (nth (multiply a a) (dec n)))) Which implementation do you think is superior? I truly have no idea.. (I'd use recur because it's easier to understand.) I read that lazy-seq is fast because is uses internal caching. But I don't see any opportunities for caching in my sample. Am I overlooking something?

• Is there a standardized (Meta?) Tag for the Date of a Website?

  - by Michael Stum

  One thing that search engines really suck with is the date when a website was created. You know the problem: You search for some CSS or JavaScript problem and Google returns a ton of results from 2002 explaining how to fix the problem in IE 5.5 and Netscape 4.6 while the helpful articles are buried on Page 3. There is only one use for Page 3, and meaningful search results are not it. Anyway, I just wonder if there is a standardized or at least generally accepted tag or meta tag that I can put on my own pages to indicate the date they were created? Not that it helps filtering out the old crap out of search results (especially since the people at #1 with their 2002 articles have zero incentive to change), but I'd just like to do my part :P

• C/C++ memory usage API in Linux/Windows

  - by minjang

  I'd like to obtain memory usage information for both per process and system wide. In Windows, it's pretty easy. GetProcessMemoryInfo and GlobalMemoryStatusEx do these jobs greatly and very easily. For example, GetProcessMemoryInfo gives "PeakWorkingSetSize" of the given process. GlobalMemoryStatusEx returns system wide available memory. However, I need to do it on Linux. I'm trying to find Linux system APIs that are equivalent GetProcessMemoryInfo and GlobalMemoryStatusEx. I found 'getrusage'. However, max 'ru_maxrss' (resident set size) in struct rusage is just zero, which is not implemented. Also, I have no idea to get system-wide free memory. Current workaround for it, I'm using "system("ps -p %my_pid -o vsz,rsz");". Manually logging to the file. But, it's dirty and not convenient to process the data. I'd like to know some fancy Linux APIs for this purpose.

• Wordpress SQL_CALC fix causes PHP error

  - by ok1ha

  I'm looking for some followup on an older topic for Wordpress where SQL_CALC was found to slow things down when you have a large DB in Wordpress. I have been using the code, at the bottom of this post, to get around it but it does generate an error in my error log. How would I prevent this error? PHP Warning: Division by zero in /var/www/vhosts/domain.com/httpdocs/wp-content/themes/greatTheme/functions.php on line 19 The original thread: http://wordpress.org/support/topic/slow-queries-sql_calc_found_rows-bringing-down-site?replies=25 The code in my functions.php: add_filter('pre_get_posts', 'optimized_get_posts', 100); function optimized_get_posts() { global $wp_query, $wpdb; $wp_query->query_vars['no_found_rows'] = 1; $wp_query->found_posts = $wpdb->get_var( "SELECT COUNT(*) FROM wp_posts WHERE 1=1 AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private')" ); $wp_query->found_posts = apply_filters_ref_array( 'found_posts', array( $wp_query->found_posts, &$wp_query ) ); $wp_query->max_num_pages = ceil($wp_query->found_posts / $wp_query->query_vars['posts_per_page']); return $wp_query; }

• Versioned cloud-based social code snippet management

  - by Chapso

  It seems a lot to ask, but I'm looking for a cloud-based solution to managing code snippets. I am looking for: Tags User accounts (I want to be able to see all of my snippets on a single page) syntax highlighting versioning - myself or others should be able to edit my snippets to improve them\ straightforward UI with minimal advertising if any Does anyone know of a solution which meets these requirements? If not, would anyone be interested in something like this? As a software engineer, after step zero (does it already exist), I'm perfectly willing to go onto step 1 (would other people use it? If so, make it).

• Converting Byte[] to String - Interbase to C# - InvalidCastException

  - by NorthernOutpost

  I'm using OleDbDataReader rdr to read a "Comments" field in BLOB form (sub_type 1 segment size 80) into a string from an Interbase DB, and I keep getting exceptions. Any suggestions? Attempt #1 ls_Chap_Comments.Add((rdr["Comments"]).ToString()); InvalidCastException: The data value could not be converted for reasons other than sign mismatch or data overflow. For example, the data was corrupted in the data store but the row was still retrievable." Attempt #2 byte[] b = new byte[100]; b = (byte[])rdr["Comments"]; string s = System.Text.ASCIIEncoding.ASCII.GetString(b); InvalidCastException: Unable to cast object of type System.String to type System.Byte[] Attempt #3 // 17 is the BLOB column zero-based location for "Comments" retval = rdr.GetBytes(17, startIndex, outbyte, 0, bufferSize); InvalidCastException: Unable to cast object of type System.String to type System.Byte[]. Any suggestions would be really appreciated!

• c# EnumerateFiles wildcard returning non matches?

  - by Sam Underhill

  As a simplified example I am executing the following IEnumerable<string> files = Directory.EnumerateFiles(path, @"2010*.xml", SearchOption.TopDirectoryOnly).ToList(); In my results set I am getting a few files which do no match the file pattern. According to msdn searchPattern wildcard is "Zero or more characters" and not a reg ex. An example is that I am getting a file name back as "2004_someothername.xml". For information there are in excess of 25,000 files in the folder. Does anyone have any idea what is going on?

• Disabling a window after SendInput()

  - by DD

  From my application I want to do two 'very basic' actions: 1. send a bunch of input (movemouse on window 'W', click, movemouse back) using SendInput() 2. disable window 'W' either by setting its layered alpha property to zero or using EnableWindow(W, FALSE). No matter what the delay between 1 and 2 is, it doesn't work. If I don't ever disable the window, if I don't do step 2, then it works great all the time. I tried putting a Sleep(10000) and it still didn't work. Window gets disabled but it doesn't receive the input. What could I be missing here?

• How to get Flex app to load quicker?

  - by Shef

  We've got an app written in Flex that displays data from our app. The .swf file is only 427kb, but it takes a full five seconds to load in Firefox. This is a headache for our users because they need to access the page that contains the app frequently. (The app displays documents, and it's really slow to march through a list of them). I've confirmed that it's not a slow web server problem. The .swf appears to be cached in the browser. Firebug reports that every time the web page accesses the .swf, the app server returns a "304 Not Modified" response, meaning that the load time from the server is almost zero. Is there anything we can do to debug this issue? Or is the Flash player just slow?

• Credit Card checksums and validations that do not require connection to the financial institution

  - by cjavapro

  The validations I know of are: Checksum the whole card number should add up to zero. (range is 0-9) Check the first digit(s) against the card type Check the length against the card type Check the CCV length against the card type (I think all the major types are 3 anyway) Of course make sure it is accepted card type as well as non expired. Are there any other validations :) (I expect many folks did not know about all of these) The reason I ask is because I overheard there was one to checksum number against expiration or CCV.. I just wanted to check.

• Sequence Point and Evaluation Order( Preincrement)

  - by Josh

  There was a debate today among some of my colleagues and I wanted to clarify it. It is about the evaluation order and the sequence point in an expression. It is clearly stated in the standard that C/C++ does not have a left-to-right evaluation in an expression unlike languages like Java which is guaranteed to have a sequencial left-to-right order. So, in the below expression, the evaluation of the leftmost operand(B) in the binary operation is sequenced before the evaluation of the rightmost operand(C): A = B B_OP C The following expression according, to CPPReference under the subsection Sequenced-before rules(Undefined Behaviour) and Bjarne's TCPPL 3rd ed, is an UB x = x++ + 1; It could be interpreted as the compilers like BUT the expression below is said to be clearly a well defined behaviour in C++11 x = ++x + 1; So, if the above expression is well defined, what is the "fate" of this? array[x] = ++x; It seems the evaluation of a post-increment and post-decrement is not defined but the pre-increment and the pre-decrement is defined. NOTE: This is not used in a real-life code. Clang 3.4 and GCC 4.8 clearly warns about both the pre- and post-increment sequence point.

• Reset JPA generated value between tests

  - by Rythmic

  I'm running spring + hibernate + JUnit with springJunit4runner and transactional set to default rollback I'm using in-memory derbydb as Database. Hibernate is used as a JPA Provider and I am successfully testing CRUD kinds of stuff. However, I have a problem with JPA and the behaviour of @GeneratedValue If I run one of my tests in isolation, two entitys are persisted with id 1 and 2. If i run the whole test suite the ids are instead 6 and 7. Spring does rollbacks just fine so there are only these two entitys in the database after addition and of course zero before. But behaviour of @GeneratedValue doesn't allow me to reliable findById unless I would return the Id from the dao.add(Entity e) //method I don't feel like doing that for the sake of testing, or is it a good practise to return the entity that was persisted so I should be doing it anyway?

• What was the most productive improvement suggestion you ever made for your team

  - by questzen

  I suggested the testing and functional teams to use Freemind map for jotting the functional flows and test steps. There was some paranoia but our module took it up and the QA teams were surprised to see near zero review comments. There was misconception among the team that there are doing more work. I assured them that by the time others would complete their work along with comment fixes, we would be going out for team lunchs and we did. The real returns came when the developers started refering to the created document in their discussions. So share your contribution(s).

• EnumJobs not returning Copies & Total Pages

  - by Hein du Plessis

  I'm using Windows API's EnumJobs to find the PageCount and Copies of a print job, but I found that these fields are almost always zero when called on a print server. Although it could be my timing is out, because the number of pages increment as the job prints and once it's done the print job cannot be accessed. So there is about half a nanosecond when the values in EnumJobs is correct before it dissapears. I've been scouring the web but can't find any help on this, just other people with similar problems. Anybody with experience with EnumJobs or can suggest other means of determining the total number of pages printed?

• C# Regex: only letters followed by an optional .

  - by TheDude

  Hello, I am looking for a way to get words out of a sentence. I am pretty far with the following expression: \b([a-zA-Z]+?)\b but there are some occurrences that it counts a word when I want it not to. E.g a word followed by more than one period like "text..". So, in my regex I want to have the period to be at the end of a word zero or one time. Inserting .? did not do the trick, and variations on this have not yielded anything fruitful either. Hope someone can help!

• Random select is not always returning a single row.

  - by Lieven

  The intention of following (simplified) code fragment is to return one random row. Unfortunatly, when we run this fragment in the query analyzer, it returns between zero and three results. As our input table consists of exactly 5 rows with unique ID's and as we perform a select on this table where ID equals a random number, we are stumped that there would ever be more than one row returned. Note: among other things, we already tried casting the checksum result to an integer with no avail. DECLARE @Table TABLE ( ID INTEGER IDENTITY (1, 1) , FK1 INTEGER ) INSERT INTO @Table SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 SELECT * FROM @Table WHERE ID = ABS(CHECKSUM(NEWID())) % 5 + 1

• Inconsistent Behavior From Declared DLL Function

  - by Steven

  Why might my GetRawData declared function return a correct value when called from my VB.NET application, but return zero when called from my ASP.NET page? The code is exactly the same except for class type difference (Form / Page) and calling event handler (Form1_Load, Page_Load). Note: In the actual code, #DLL# and #RAWDATAFILE# are both absolute filenames to my DLL and raw data file respectively. Note: The DLL file was not created by Visual Studio. Form1.vb Public Class Form1 Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Private Sub Form1_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length) Default.aspx.vb Partial Public Class _Default Inherits System.Web.UI.Page Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Me.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length)

• Merging two arrays in PHP

  - by Industrial

  Hi everyone, I am trying to create a new array from two current arrays. Tried array_merge, but it will not give me what I want. $array1 is a list of keys that I pass to a function. $array2 holds the results from that function, but doesn't contain any non-available resuls for keys. So, I want to make sure that all requested keys comes out with 'null':ed values, as according to the shown $result array. It goes a little something like this: $array1 = array('item1', 'item2', 'item3', 'item4'); $array2 = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3' ); Here's the result I want: $result = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3', 'item4' => '' ); It can be done this way, but I don't think that it's a good solution - I really don't like to take the easy way out and suppress PHP errors by adding @:s in the code. This sample would obviously throw errors since 'item4' is not in $array2, based on the example. foreach ($keys as $k => $v){ @$array[$v] = $items[$v]; } So, what's the fastest (performance-wise) way to accomplish the same result?
