  • Lightweight PHP5 based template class/system

    - by Wizzard
    Hi there. Looking at using a template system for a new project, it's only a small site and don't want to use the overhead and 'complexity' of smarty. I don't really like template systems that force you to make use of another language just to make it easier for designers (apparently). Something like this http://www.namepros.com/code/517342-php5-template-class.html is what Im looking at but something which is a bit more robust and proven.

  • wpf window ghosting problem when resizing over two screens

    - by bluebit
    The title pretty much describes it. If I resize my WPF app so that it stretches over two monitors in a dual monitor setup, and resize it back, there will be a ghost window in the second monitor that does nothing, but is still moved when I move the original window in the first screen. Has anyone had issues like this? I think its a refresh bug on some OSs (I use WINXP 32 bit), but would like to confirm with the community.

  • why does vb not support multiple inheritance?

    - by isolatedIterator
    I've seen some discussion on why c# does not implement multiple inheritance but very little as to why it isn't supported in vb. I understand that both c# and vb are compiled down to intermediary language and so they both need to share similar restrictions. The lack of multiple inheritance in VB seems to have been given as one reason for the lack of the feature in dot net. Does anyone know why VB doesn't support multiple inheritance? I'm hoping for a bit of history lesson and discussion on why this was never considered for VB.

  • JVM throws OutOfMemory during gc though there are plenty memory left...

    - by Shu L.
    I have my java application configured to use 5G memory. I got an OutOfMemory out of blue. I inspected the gc log and found plenty of memory left: young generation occupies 4% allocated space, tenure generation occupancy is 5% and perm generation is 43%. I am puzzled why JVM throws an OutOfMemory at the gc time. Does anyone know why this is happening? Your help is greatly appreciated. JVM memory and gc settings: -server -Xms5g -Xmx5g -Xss256k -XX:NewSize=2g -XX:MaxNewSize=2g -XX:+UseParallelOldGC -XX:+UseTLAB -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90 -XX:+DisableExplicitGC gc.log 2009-09-19T03:34:59.741+0000: 92836.778: [GC Desired survivor size 152567808 bytes, new threshold 1 (max 15) [PSYoungGen: 1941492K-144057K(1947072K)] 3138022K-1340830K(5092800K), 0.1947640 secs] [Times: user=0.61 sys=0.01, real=0.19 secs] 2009-09-19T03:35:29.918+0000: 92866.954: [GC Desired survivor size 152109056 bytes, new threshold 1 (max 15) [PSYoungGen: 1941625K-144049K(1948608K)] 3138398K-1341080K(5094336K), 0.1942000 secs] [Times: user=0.61 sys=0.01, real=0.20 secs] 2009-09-19T03:35:56.883+0000: 92893.920: [GC Desired survivor size 156565504 bytes, new threshold 1 (max 15) [PSYoungGen: 1567994K-115427K(1915072K)] 2765026K-1312820K(5060800K), 0.1586320 secs] [Times: user=0.50 sys=0.01, real=0.16 secs] 2009-09-19T03:35:57.042+0000: 92894.079: [GC Desired survivor size 179961856 bytes, new threshold 1 (max 15) [PSYoungGen: 115427K-0K(1898560K)] 1312820K-1313987K(5044288K), 0.0775650 secs] [Times: user=0.42 sys=0.19, real=0.08 secs] 2009-09-19T03:35:57.120+0000: 92894.157: [Full GC [PSYoungGen: 0K-0K(1898560K)] [ParOldGen: 1313987K-159522K(3145728K)] 1313987K-159522K(5044288K) [PSPermGen: 20025K-19942K(40256K)], 0.56923 00 secs] [Times: user=2.18 sys=0.05, real=0.57 secs] 2009-09-19T03:35:57.690+0000: 92894.726: [GC Desired survivor size 197066752 bytes, new threshold 1 (max 15) [PSYoungGen: 0K-0K(1745728K)] 159522K-159522K(4891456K), 0.0072590 secs] [Times: user=0.01 sys=0.00, real=0.00 secs] 2009-09-19T03:35:57.698+0000: 92894.734: [Full GC [PSYoungGen: 0K-0K(1745728K)] [ParOldGen: 159522K-158627K(3145728K)] 159522K-158627K(4891456K) [PSPermGen: 19942K-19934K(45504K)], 0.3280480 secs] [Times: user=1.46 sys=0.00, real=0.33 secs] Heap PSYoungGen total 1745728K, used 87233K [0x00002aab73650000, 0x00002aabf3650000, 0x00002aabf3650000) eden space 1745664K, 4% used [0x00002aab73650000,0x00002aab78b80778,0x00002aabddf10000) from space 64K, 0% used [0x00002aabddf10000,0x00002aabddf10000,0x00002aabddf20000) to space 192448K, 0% used [0x00002aabe7a60000,0x00002aabe7a60000,0x00002aabf3650000) ParOldGen total 3145728K, used 158627K [0x00002aaab3650000, 0x00002aab73650000, 0x00002aab73650000) object space 3145728K, 5% used [0x00002aaab3650000,0x00002aaabd138d28,0x00002aab73650000) PSPermGen total 45504K, used 19965K [0x00002aaaae250000, 0x00002aaab0ec0000, 0x00002aaab3650000) object space 45504K, 43% used [0x00002aaaae250000,0x00002aaaaf5cf668,0x00002aaab0ec0000) I am on 64-bit Linux and JRE 1.6.0_10: $uname -a Linux x 2.6.24-etchnhalf.1-amd64 #1 SMP Tue Oct 14 03:11:45 UTC 2008 x86_64 GNU/Linux $java -version java version "1.6.0_10" Java(TM) SE Runtime Environment (build 1.6.0_10-b33) Java HotSpot(TM) 64-Bit Server VM (build 11.0-b15, mixed mode)

  • How to open DataSet in Visual Studio 2008 faster?

    - by Ekkapop
    When I open DataSet in Visual Studio 2008 to design or modify it, it always take a very long time (more than five minutes) before I can continue to do my job. While I'm waiting I can't do anything on Visual Studio, moreover CPU and memory usage is growth dramatically. I want to know, Is it has anyway to reduce this waiting time? Hardware - Desktop CPU: Intel Q6600 Memory: 4 GB HDD: 320 GB 7200 rpm OS: Windows XP 32 bit with Service Pack 3

  • using FUSLOGVW.EXE on a machine with no Visual Studio installed

    - by Gerrie Schenck
    I'm currently having some assembly binding problems on our development server. I want to investigate the problem a bit further with Fusion Log Viewer. Since there is no Visual Studio installed on the machine, I copied FUSLOGVW.EXE to a local folder and started it there. Is this supposed to work or does it need something else? I don't get the impression the application is logging any failures (and yes I have the settings right).

  • little oh notation as the limit of n goes to infinity

    - by Tony
    Hi all, I'm just trying to understand how in little o notation this is true: f(n)/g(n) as n goes to infinity = infinity? Can someone explain that to me? I do get the idea that f(n) = o(g(n)) means that f(n) grows no faster then cg(n) for all constants c 0. I just don't get the bit in bold above.

  • Crazy python behaviour

    - by Martin
    I have a little piece of python code in the server script for my website which looks a little bit like this: console.append([str(x) for x in data]) console.append(str(max(data))) quite simple, you might think, however the result it's outputting is this: ['3', '12', '3'] 3 for some reason python thinks 3 is the max of [3,12,3]! So am I doing something wrong? Or this is misbehaviour on the part of python?

  • What code have you written with #pragma you found useful?

    - by Xavier Ho
    I've never understood the need of #pragma once when #ifndef #define #endif always works. I've seen the usage of #pragma comment to link with other files , but setting up the compiler settings was easier with an IDE. What are some other usages of #pragma that is useful, but not widely known? Edit: I'm not just after a list of #pragma directives. Perhaps I should rephrase this question a bit more: What code have you written with #pragma you found useful?

  • Animated transitions for jQuery UI's sortable

    - by Heilemann
    Just out of curiosity, as I haven't been able to find anything anywhere; does anyone know of a way to get jQuery UI's sortable function to animate its sorting? What I mean is, when you move an element around the sortable parent, its children, the sortables, skip around instead of smoothly animating to their new position, which besides from being an eyesore can also make it a bit difficult to figure out what has moved where. There's obviously no default option for this, but I was hoping that perhaps someone, somewhere, had a neat solution.

  • PDO/Oracle vs OCI

    - by jarcoal
    The company I work for currently uses some basic functions to abstract the OCI libraries as a means for DB connectivity. We're considering switching to PHP's PDO object, but from some quick searches, it looks like the Oracle driver is a bit less mature than the other PDO drivers. I would appreciate some pro/cons for PDO/Oracle from anyone who has used it in a production environment. Thanks!

  • Dots and spaces in variable names from external sources are converted to underscores

    - by Brandon
    Trying a bit of AJAX, and I find that much of my data is littered with underscores! Documentation confirms that this is working as intended. Any way to pass my form information to PHP intact? I'm using CodeIgniter, so my pass looks like /controller/function/variable, receiving controller: controller{ function($v=0){#what once was hello world is now hello_world...} } I can't very well do an undo, data might contain an underscore. Thanks, Brandon

  • How can I execute pl/pgsql code without creating a function?

    - by Jeremiah Peschka
    With SQL Server, I can execute code ad hoc T-SQL code with full procedural logic through SQL Server Management Studio, or any other client. I've begun working with PostgreSQL and have run into a bit of a difference in that PGSQL requires any logic to be embedded in a function. Is there a way to execute PL/PGSQL code without creating an executing a function?

  • memcpy segmentation fault on linux but not os x

    - by Andre
    I'm working on implementing a log based file system for a file as a class project. I have a good amount of it working on my 64 bit OS X laptop, but when I try to run the code on the CS department's 32 bit linux machines, I get a seg fault. The API we're given allows writing DISK_SECTOR_SIZE (512) bytes at a time. Our log record consists of the 512 bytes the user wants to write as well as some metadata (which sector he wants to write to, the type of operation, etc). All in all, the size of the "record" object is 528 bytes, which means each log record spans 2 sectors on the disk. The first record writes 0-512 on sector 0, and 0-15 on sector 1. The second record writes 16-512 on sector 1, and 0-31 on sector 2. The third record writes 32-512 on sector 2, and 0-47 on sector 3. ETC. So what I do is read the two sectors I'll be modifying into 2 freshly allocated buffers, copy starting at record into buf1+the calculated offset for 512-offset bytes. This works correctly on both machines. However, the second memcpy fails. Specifically, "record+DISK_SECTOR_SIZE-offset" in the below code segfaults, but only on the linux machine. Running some random tests, it gets more curious. The linux machine reports sizeof(Record) to be 528. Therefore, if I tried to memcpy from record+500 into buf for 1 byte, it shouldn't have a problem. In fact, the biggest offset I can get from record is 254. That is, memcpy(buf1, record+254, 1) works, but memcpy(buf1, record+255, 1) segfaults. Does anyone know what I'm missing? Record *record = malloc(sizeof(Record)); record->tid = tid; record->opType = OP_WRITE; record->opArg = sector; int i; for (i = 0; i < DISK_SECTOR_SIZE; i++) { record->data[i] = buf[i]; // *buf is passed into this function } char* buf1 = malloc(DISK_SECTOR_SIZE); char* buf2 = malloc(DISK_SECTOR_SIZE); d_read(ad->disk, ad->curLogSector, buf1); d_read(ad->disk, ad->curLogSector+1, buf2); memcpy(buf1+offset, record, DISK_SECTOR_SIZE-offset); memcpy(buf2, record+DISK_SECTOR_SIZE-offset, offset+sizeof(Record)-sizeof(record->data));
