• importing content into drupal.

  - by anru

  I have a wordpress site with 5k post and each post has average 25 comments. so 125k total nodes have to be added. I need import those posts and comments into drupal 6 . I have written a script to import those post/comments into drupal by drupal's cron service. but the cron service keeps time out. because import 125k nodes one by one is very slow. what can i do to imporve drupal importing speed? i am use drupal built in node_save(), comment_save() method to do it. I have not find out a way to use customized SQL query to increase importing speed yet. I am execute my script through drupals's cron.php, that mean even i have set 'max_execute_time' to unlimited, but that only affects PHP , apache server has it own time out setting.

• Do MyISAM holes get filled in automatically?

  - by NNN

  When you run a delete on a MyISAM table, it leaves a hole in the table until the table is optimized. This affects concurrent inserts. On the default setting, concurrent_inserts only work for tables without holes. However, in the documentation for MyISAM, under the concurrent_insert section it says: Enables concurrent inserts for all MyISAM tables, even those that have holes. For a table with a hole, new rows are inserted at the end of the table if it is in use by another thread. Otherwise, MySQL acquires a normal write lock and inserts the row into the hole. http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_concurrent_insert Does that mean MyISAM automatically fills in holes whenever a new row is insert into the table? Previously I thought the holes would not be fixed until you OPTIMIZE a table.

• Create an autocompleter like the Facebook status update

  - by Terw

  Hello I'm trying to create a div with contenteditable like the Facebook status update. Then I mean I want to show an autocomplete box when the user have written @. How would you do that. Currently I'm just playing with keypress and check if the keycode = 64. Somehow that works, but it doesn't validate if there's a space before the alfa, or if the user has unfocused the box, then focused it again. Any ideas? Or do you know about any plugin that works something like that? Tnx

• Rack layout tools

  - by Luke

  I'm wondering if there's any tools (preferably offline) that would allow me to layout all of the new equipment that will be going into several standard racks. Currently I'm using Excel to map out all of the slots columns for the data but I suspect that there is some better method of doing this. Suggestions? Edit: Dell has an online tool, but doesn't seem very good at actually saving the data that you're working on (and obviously it's geared towards Dell hardware).

• Looking for a free tool to visualize object relationships for C#

  - by vfilby

  Here is my ideal solution: a free tool that reads a .csporj or .sln and generates a pretty picture that shows all the objects and how they are related. By relationships, I don't mean inheritance but rather dependency. For example, if we have a Car object and Car has a member variable Wheel, I would like that Car depends on Wheel to be visualized in the graph. I know visual studio can do inheritance graphs, but that is only half of what I am looking for. Is what I am looking for possible? Are there any tools that do something similar? Related question for java: http://stackoverflow.com/questions/1824261/are-there-any-tools-to-visualize-the-objects-being-used-in-a-program

• "Disabling" an HTML table with javascript

  - by Blair Jones

  I've seen this done in a lot of sites recently, but can't seem to track one down. Essentially I want to "disable" an entire panel (that's in the form on an HTML table) when a button is clicked. By disable I mean I don't want the form elements within the table to be usable and I want the table to sort of fade out. I've been able to accomplish this by putting a "veil" over the table with an absolutely positioned div that has a white background with a low opacity (so you can see the table behind it, but can't click anything because the div is in front of it). This also adds the faded effect that I want. However, when I set the height of the veil to 100% it only goes to the size of my screen (not including the scrolling), so if a user scrolls up or down, they see the edge of the veil and that's not pretty. I'm assuming this is typically done in a different fashion. Does anyone have some suggestions as a better way to accomplish this?

• JPA query for getting the whole tree

  - by Javi

  Hello, I have a class which models all categories and they can be ordered hierarchically. @Entity @Table(name="categories") public class Category { @Id @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="sequence") @SequenceGenerator(name="sequence", sequenceName="categories_pk_seq", allocationSize=1) @Column(name="id") private Long id; @Column private String name; @OneToOne @JoinColumn(name="idfather") private Category father; } I need to get all categories ordered hierarchically (I mean every father followed by its children and fathers ordered alphabetically on each level) as they could be made for example with PRIOR in oracle. Is it possible to do this with a JPA Query (not a SQL one)? Thanks.

• Getting 'error while loading shared libraries' when using -L to specifically find the library.

  - by e5

  I've been trying to solve this for a few hours now. I am compiling some c files using gcc. The files require libpbc, so I am using the -L flag to point gcc at the directory which contains libpbc.so.1. The code compiles without error yet when I attempt to run it I get the following error message: ./example.out: error while loading shared libraries: libpbc.so.1: cannot open shared object file: No such file or directory Looking at similar questions this error message seems to indicate that gcc can't find libpbc.so.1. I know gcc sees libpbc.so.1 because when I rename libpbc.so.1 to something else it fails to compile. I am using -L to point to the directory which contains libpbc.so.1. Not sure what next steps I can take to figure this out. Would appreciate any ideas. What does this error message mean exactly?

• Will more CPUs/cores help with VS.NET build times?

  - by LoveMeSomeCode

  I was wondering if anyone knew whether Visual Studio .NET had a parallel build process or not? I have a solution with lots of projects, every project has lots of markup/code, lots of types, etc. Just sitting there with intellisense on runs it up to about 700MB. But the build times are really slow and only seem to max out one of my two cpu cores. Does this mean the build process is single threaded? My solution's build dependency chain isn't linear, so I don't see why it couldn't be building some of the projects in parallel. I remember Joel Spolsky blogging about his new SSD, and how it didn't help with compile times, but he didn't mention which compiler he was using. We're using VS 2005. Anyone know how it's compilation works? And is it any different/better in 2008/2010?

• Vim + OmniCppComplete: Completing on Class Members which are STL containers

  - by Robert S. Barnes

  Completion on class members which are STL containers is failing. Completion on local objects which are STL containers works fine. For example, given the following files: // foo.h #include <string> class foo { public: void set_str(const std::string &); std::string get_str_reverse( void ); private: std::string str; }; // foo.cpp #include "foo.h" using std::string; string foo::get_str_reverse ( void ) { string temp; temp.assign(str); reverse(temp.begin(), temp.end()); return temp; } /* ----- end of method foo::get_str ----- */ void foo::set_str ( const string &s ) { str.assign(s); } /* ----- end of method foo::set_str ----- */ I've generated the tags for these two files using: ctags -R --c++-kinds=+pl --fields=+iaS --extra=+q . When I type temp. in the cpp I get a list of string member functions as expected. But if I type str. omnicppcomplete spits out "Pattern Not Found". I've noticed that the temp. completion only works if I have the using std::string; declaration. How do I get completion to work on my class members which are STL containers? Edit I found that completion on members which are STL containers works if I make the follow modifications to the header: // foo.h #include <string> using std::string; class foo { public: void set_str(const string &); string get_str_reverse( void ); private: string str; }; Basically, if I add using std::string; and then remove the std:: name space qualifier from the string str; member and regenerate the tags file then OmniCppComplete is able to do completion on str.. It doesn't seem to matter whether or not I have let OmniCpp_DefaultNamespaces = ["std", "_GLIBCXX_STD"] set in the .vimrc. The problem is that putting using declarations in header files seems like a big no-no, so I'm back to square one.

• Hibernate and stored procedures

  - by cc96ai

  As my understanding on setting hibernate, I need to create table meta data file (person.hbm.xml), include all the fields mapping java object (person.java) If we use stored procedures for all transaction, do we still need the above configuration? It seems hibernate and stored procedures will overlap, We set up the stored procedure because we don't want the to developer know all the field in db. If tables change, then we need update above files. Does it mean if we purely use stored procedure, we should just go for JDBC? If hibernate, we should stay in HQL?

• What is the maximum length in seconds to store a value in memcache

  - by Emilien

  The Google App Engine memcache documentation states that the time parameter of memcache.set() is an "Optional expiration time, either relative number of seconds from current time (up to 1 month), or an absolute Unix epoch time." So I tried to set a value for 30 days, which according to Google is 2 592 000 seconds. However, I highly suspect that this value is too high, because the value was set (memcache.set() returned the value True), but a memcache.get() just after always returned None. Reducing this value to 1 728 000 seconds just worked fine/as expected. I guess that once passed the highest value, the time parameter gets interpreted as an absolute Unix epoch time. That would mean that 2 592 000 seconds got interpreted as "Sat, 31 Jan 1970 00:00:00 GMT", which is obviously a date in the past... So what is the highest value you can enter that will get interpreted as a number of seconds in the future?

• Careers in Computer Security? [closed]

  - by Joey Green

  I have the opportunity to go back for MSCS and the closest college's main research is in computer security and forensics. I've always been interested in computer networks and security but I have no interest whatsoever to run cables or add users to the network( which is what the network people do where I currently work ). I wanted to know how may I find out the types of day to day task a computer security expert does? I don't mean the jobs you find on dice or indeed. I'm talking about the type of careers that start out at the NSA or DIA. Also, I'm wondering what the pay is like for these types of fields? Thanks to all that reply.

• Server crash = How does a TCP/IP (and the browser-client) behave after this?

  - by jens

  Hello Experts, i would be thankfull for an explanation what happens with HTTP(TCP/IP) transmissions when the server crashes unexpectedly, how does the client Browser (Firefox / IE) handle this event. What happens in the following two standard cases: Clients-actively sends data: The TCP/IP Connection has been estableshed and the Client (Web-Browser) is Sending a POST Request with some data and in the middle of the process of sending the server crashes. What does this mean for the client? As far as I know TCP/IP does not "acknowledge" a send data-package so the client does not know that the server crashed. How will the client behave? (Firefox and Internet Explorer)? The Server is actively sending data: As above the tcp/ip connection has been established and the Server is sending a large website to the client (browser). In the middle of the sending-process the server crashes, so no futher packets are sent. How does the client browser react to this event (Firefox and Interne Expolrer) Thank you very much!! Jens

• Is there a config option in PHP to prevent undefined constants from being interpreted as strings?

  - by mrbinky3000

  This is from the php manual: http://us.php.net/manual/en/language.constants.syntax.php If you use an undefined constant, PHP assumes that you mean the name of the constant itself, just as if you called it as a string (CONSTANT vs "CONSTANT"). An error of level E_NOTICE will be issued when this happens. I really don't like this behavior. If I have failed to define a required constant, I would rather the script fail so that I am forced define it. Is there any way to force PHP to crash the script if it tries to use an undefined constant? For example. Both of these scripts do the same thing. <?php define('DEBUG',1); if (DEBUG) echo('Yo!'); ?> and <?php if(DEBUG) echo('Yo!'); ?> I would rather the second script DIE and declare that it tried to use an undefined constant DEBUG.

• Is there any simple way to test two PNGs for equality?

  - by Mason Wheeler

  I've got a bunch of PNG images, and I'm looking for a way to identify duplicates. By duplicates I mean, specifically, two PNG files whose uncompressed image data are identical, not necessarily whose files are identical. This means I can't do something simple like compare CRC hash values. I figure this can actually be done reliably since PNGs use lossless compression, but I'm worried about speed. I know I can winnow things down a little by testing for equal dimensions first, but when it comes time to actually compare the images against each other, is there any way to do it reasonably efficiently? (ie. faster than the "double-for-loop checking pixel values against each other" brute-force method?)

• DNS Lookup in ASP / ASP.Net

  - by Dave Forgac

  I have a Windows server that is intermittently losing the ability to lookup DNS information. I'm trying to get to the root cause of the problem but in the mean time I'd like to be able to monitor whether the server can perform lookups. Basically, it should attempt to lookup some common hostnames and the display 'Success' if the lookups are successful. I see lots of examples of doing this with third party components in ASP but I would prefer to be able to do this with a single ASP / ASP.Net script that would be portable and not require anything additional be installed.

• How to Serialize a WPF Drawing?

  - by Néstor Sánchez A.

  Hi, maybe I'm missing something. I believed that WPF vector-based Drawings (like DrawingGroup, DrawingGeometry, etc.) were ready to be serialized. But they are not. So, should I navigate all these drawing childrens, and store they points, lines, brushes (that also are not serializable) and so on, and then made my custom serialization? Is really that difficult or I'm missing something pretty obvious? I mean, even serializing Bitmap images is easy. I thinked serializing vector-based drawings were easier (no quality loss, just descriptive info, no massive data). Thanks for your practical answers, alternate-way suggestions and comments!
