• DB2 increase bufferpool size and compressed tables not equal better performance. Why?

  - by Mestika

  Hi, I’m working on tuning and increasing the performance of my IBM DB2 version 9.7 database. I’ve been searching around the net for the last couple of days and learned that if I created my tables in COMPRESS mode and created one more bufferpool and set both of them to access 1024mb, then the performance in my queries should increase because of the less I/Os to the disks. However, when I run my time analysis, the performance Decrease. I added the new additions to my regular database with the indexes I’ve used all the time. Each time I search google I come up with the statement that: Increased bufferpool size and several bufferpools AND a table compression SHOULD prove to get better performance. I’m very puzzled about the total unexpected result. Are there some tuning mechanisms I’ve forgot or does anyone have a explanation for this odd behavior? Sincerely Mestika

• UIScrollView with over 100 images

  - by tikkips

  I have implemented a UIScrollView on the iPhone that contains 100 image slots which I fill only the currently visible page, the one before it, and the one after it as the user scrolls. Everything works fine until we get up to image 97 or 98, the entire view disappears! The only thing I can do at that point is navigate back to the previous view. Nothing works as far as the scroll view after this. I am not receiving any memory warnings an the rest of the app functions fine. Any ideas? Has anyone created a UIScrollView in paging mode with over 100 pages? Rick

• Can you data bind to a property that contains parameter in Silverlight?

  - by rip

  In silverlight, can you bind to a property that contains parameter? For example, the following doesn’t seem to work. Am I missing something or is this not possible? C# private System.Collections.Generic.Dictionary<string, string> ValuesField = new System.Collections.Generic.Dictionary<string, string>(); public string Value { get { return ValuesField(FieldName); } set { ValuesField(FieldName) = value; } } VB Private ValuesField As New System.Collections.Generic.Dictionary(Of String, String) Public Property Value(ByVal FieldName As String) As String Get Return ValuesField(FieldName) End Get Set(ByVal value As String) ValuesField(FieldName) = value End Set End Property XAML <TextBox Name="TextBox1" VerticalAlignment="Top" Width="120"Text="{Binding Path=Value[MyField],Mode=TwoWay }" />

• Millisecond-Accurate Scheduling of Future Events in C++/CLI

  - by A Grad Student at a University

  I need to create a C++/CLI mixed assembly that can schedule future calls into a native DLL with millisecond accuracy. This will, of course, mean setting a timer (what kind?) for a millisecond or three beforehand, then spinning until the moment and calling the native DLL function. Based on what I've read, I would guess that the callback that the timer calls will need to be native to make sure there are no thunks or GC to delay handling the timer callback. Will the entire thread or process need to be native and CLR-free, though, or can this be done just as accurately with #pragma unmanaged or setting one file of the assembly to compile as native? If so, how? If there is indeed no way to do this in mixed-mode C++/CLI, what would be the easiest way to set up an app/thread (ie, DLL or exe?) to handle it and to get the data back and forth between the native and managed threads/apps?

• prevent linux thread from being interrupted by scheduler

  - by johnnycrash

  How do you tell the thread scheduler in linux to not interrupt your thread for any reason? I am programming in user mode. Does simply locking a mutex acomplish this? I want to prevent other threads in my process from being scheduled when a certain function is executing. They would block and I would be wasting cpu cycles with context switches. I want any thread executing the function to be able to finish executing without interruption even if the threads' timeslice is exceeded.

• Data 'logger' turning off when phone goes to standbymode

  - by Marko Järvenpää

  I'm creating a datalogger which logs the gps data and the sensor data of the phone. I've just a strange problem. If the phone is not touched for few minutes it goes into standby mode (screen goes black), and that causes the logger to stop working. Actually the firewriting in the logger stops working. The GPS resumes fine after coming out of blackscreen, but when I check the log I created it only shows saved points for few minutes. Does anyone have idea what is causing this?

• C++ performance, optimizing compiler, empty function in .cpp

  - by Dodo

  I've a very basic class, name it Basic, used in nearly all other files in a bigger project. In some cases, there needs to be debug output, but in release mode, this should not be enabled and be a NOOP. Currently there is a define in the header, which switches a makro on or off, depending on the setting. So this is definetely a NOOP, when switched off. I'm wondering, if I have the following code, if a compiler (MSVS / gcc) is able to optimize out the function call, so that it is again a NOOP. (By doing that, the switch could be in the .cpp and switching will be much faster, compile/link time wise). --Header-- void printDebug(const Basic* p); class Basic { Basic() { simpleSetupCode; // this should be a NOOP in release, // but constructor could be inlined printDebug(this); } }; --Source-- // PRINT_DEBUG defined somewhere else or here #if PRINT_DEBUG void printDebug(const Basic* p) { // Lengthy debug print } #else void printDebug(const Basic* p) {} #endif

• Can I install Whizzy for Emacs on a Mac (is Mac OS X a unix environment)?

  - by Vivi

  I think my question is pretty stupid, but here it goes: I am using Aquamacs, and I want to install the Whizzy mode. The website for Whizzy says that "it is designed for Unix platforms". I read that Mac OS X is unix certified, but does that mean I can install Whizzy on my mac? If yes, can I install and use it with Aquamacs or do I have to use the Emacs running from the terminal? PS: I don't know whether this question should be posted here or on SuperUser, but as Emacs users seem to hang out here more often, this is the place I chose.

• Notepad++ like "multi editing" in VIM?

  - by proto-n

  I'm switching from Notepad++ to VIM as main text editor. Notepad++ can have multiple cursors by holding down ctrl and clicking anywhere in the text, so if you type, the text appears in multiple locations. Is it possible in vim? Something like insert after selecting multiple rows in visual mode, but with the possibility to have cursors anywhere in the text. It's a feature I rarely use, also it's quite easily avoidable, I'm just curious, since its the only one I could't find a replacement for in vim yet.

• Trying to use the "Use Specific Printer" option in Access 2007

  - by garynei

  I am trying to set a report to use a specific printer. I go into design mode, click on the page setup ribbon, click the page setup bottun, go into the page tabt, click the option to choose a specific printer, and then click the printer button to choose the printer I want to use. I save the steps and exit out of the report, but it still goes back and prints from the default printer. Why? I had no problems with this feature in 2003, why am I having problems in 2007. Any suggestions on how to fix this problem would be greatly appreciated, thanks.

• Why is hierarchyviewer not working for Samsung Galaxy TAB 7.0?

  - by FireAndIce

  I've used hierarachyviewer earlier, but on android emulator. It works absolutely fine when I use it on the emulator. However it does not work with Samsung Galaxy TAB 7.0, with Android 2.3.4. This is the log, that I get 11:04:22 E/hierarchyviewer: Unable to get view server version from device 303599 64881B00EC 11:04:22 E/hierarchyviewer: Unable to get view server protocol version from devi ce 30359964881B00EC 11:04:24 E/hierarchyviewer: Unable to debug device 30359964881B00EC 11:05:05 E/hierarchyviewer: Unable to get view server version from device 303599 64881B00EC 11:05:05 E/hierarchyviewer: Unable to get view server protocol version from devi ce 30359964881B00EC 11:05:07 E/hierarchyviewer: Unable to debug device 30359964881B00EC 11:09:38 E/hierarchyviewer: Unable to get view server version from device 303599 64881B00EC 11:09:38 E/hierarchyviewer: Unable to get view server protocol version from devi ce 30359964881B00EC 11:09:40 E/hierarchyviewer: Unable to debug device 30359964881B00EC I'm also not using hierarchyviewer in the debug mode, just running the application.

• x86 Assembly - printf doesn't print without "\n"

  - by Bitani

  So I'm confused. I'm going through the book "Programming from the Ground Up" and am working with using libraries. printf is working just fine so long as I include a "\n" in the string, but without it it will print absolutely nothing. Any idea why this happens? Code: .section .data my_str: .ascii "Jimmy Joe is %d years old!\n\0" my_num: .long 76 .section .text .globl _start _start: pushl my_num pushl $my_str call printf movl $1, %eax movl $0, %ebx int $0x80 Also, when I use -m elf_i386 for 32-bit mode and -dynamic-linker /lib/ld-linux.so.2 -lc to link, I get the warning ld: skipping incompatible /usr/lib64/libc.so when searching for -lc If that makes any difference, or if anybody has any suggestions as to how to have it load the 32-bit library directly. Thanks!

• URL rewrite to remove parameters

  - by samoyed

  Hello to all, I'm working on a site where all the pages are actually index.php + a 'name' parameter that is analyzed and loads the appropriate template and content. the homepage url is: http://www.some_site.com/?page=homepage 1. i was asked to "change" the homepage url to: http://www.some_site.com can i use url rewite and htaccess for that and if so, what should i write there? working on my local machine, i tried this code (mode rewrite is enabled): <IfModule mod_rewrite.c> Options +FollowSymLinks RewriteEngine On RewriteRule /index.php /index.php?page=homepage </IfModule> i would still need the 'name' parameter to be available to the php code of course, so i can load the template and css files. 2. it would be nice for other pages (not homepage) to be converted from (example) http://www.some_site.com/?page=products to: http://www.some_site.com/products this is less crucial. thanx in advance and have a nice day :-)

• Profiling help required

  - by Mick

  I have a profiling issue - imagine I have the following code... void main() { well_written_function(); badly_written_function(); } void well_written_function() { for (a small number) { highly_optimised_subroutine(); } } void badly_written_function() { for (a wastefully and unnecessarily large number) { highly_optimised_subroutine(); } } void highly_optimised_subroutine() { // lots of code } If I run this under vtune (or other profilers) it is very hard to spot that anything is wrong. All the hotspots will appear in the section marked "// lots of code" which is already optimised. The badly_written_function() will not be highlighted in any way even though it is the cause of all the trouble. Is there some feature of vtune that will help me find the problem? Is there some sort of mode whereby I can find the time taken by badly_written_function() and all of its sub-functions?

• How do I create an empty file in emacs?

  - by Singletoned

  How can I create an empty file from emacs, ideally from within a dired buffer? For example, I've just opened a Python module in dired mode, created a new directory, opened that in dired, and now need to add an empty __init__.py file in the directory. If I use C-x C-f __init__.py RET C-x C-s then emacs doesn't create the file because no changes have been made to it. I would have to type in the file, save it, delete my typing and then save it again for that to work. Thanks

• How to move partition with Users to a new SATA controller?

  - by Al Kepp

  Our current situation: X79 chipset. Windows 7 installed on SATA SSD running on Marvell controller. C:\Users contains just Public and computer-name folders, all the other users are created in E:\Users. That partition is on two HDD's running on an Intel RAID controller. (The motherboard has got two SATA/RAID onboard controllers.) The goal is: Without reinstallation, I want to move SSD to a standard SATA controller. Then I want to get rid of RAID1, and move one HDD to the same internal Intel SATA controller and the current E:\Users move to that new place. I want it to stay as E:\users, but I need to reinstall the HDD to let it work in SATA mode without RAID. So I face several problems. I am sure all are solvable with free software utilities, but I don't know how exactly to do it. I can see the particular problems: I have got all users at E:\Users. When I turn off that E:\ disk, I won't be able to login to Windows. I need at least one admin account to be placed back at C:\users. The current C: runs on standard 120 GB SSD, but it is connected to a Marvell SATA/RAID controller. I am affraid the Windows won't let me put it to Intel SATA controller due to hardware/licence check, and I won't be able to use standard W7 recovery disk either, because there probably isn't marvel SATA/RAID driver on it. I haven't tried anything yet, because I am affraid I can end up with computer not working at all. (I want to move it to a standard ICH10 Intel SATA controller to let us have no problems in future with it. I think it is not very safe when we use any nonstandard hardware to boot the computer.) I need to somehow backup current E:\ disk and restore it to a new E:. I hope this will be the easy part (as long as the admin account will reside on C:). The E: RAID array is very large, but it is almost empty (less than 100 GB of data.) So I can make the partition smaller so it can easily fit to a single SATA HDD.

• Erase part of RenderTarget when drawing primitives?

  - by user1495173

  I'm creating a paint like application using XNA. I have a render target which acts as a canvas. When the user draws something I draw corresponding triangles using DrawUserPrimitives and triangle strips to make lines and other curves. I want to implement an eraser in the application, so that the user can erase the triangles from the texture. I've used OpenGL in the past and there I would just use a blend function like so: glBlendFunc(GL_ZERO, GL_ONE_MINUS_SRC_ALPHA); How would I do this in XNA? I tried setting the GraphicsDevice blend mode to AlphaBlend, Additive, etc.. but it did not work. Any ideas? Thanks!

• Is there a way to replicate a very large file shares in real-time?

  - by fsckin

  I have an hourly cron job that copies about 40GB of data from a source folder into a new folder with the hour appended on the end. When it's done, the job prunes anything older than 24 hours. This data changes very often during work hours and is on a samba file share. Here's how the folder structure looks: \server\Version.1 \server\Version.2 \server\Version.3 ... \server\Version.24 The contents of each new folder compared to the last one usually doesn't change very much, since this is a hourly job. Now you might be thinking that I'm an idiot for setting dreaming this up. Truth is, I just found out. It's actually been used for years and is so incredibly simple, anyone could delete the ENTIRE 40GB share (imagine that dialog spooling up... deleting thousands and thousands of files) and it would actually be faster to restore by moving the latest copy back to the source than it took to delete. Brilliant! Now to top this off, I need to efficiently replicate this 960GB of "mostly similar" data to a remote server over WAN link, with the replication happening as close to real-time as possible -- think hot spare, disaster recovery, etc. My first thought was rsync. Total failure. Rsync sees it sees a deletion of the folder that is 24 hours old and the addition of a new folder with 30GB of data to sync! I also looked at rdiff-backup and unison, they both appear to use similar algorithms and do not keep enough meta-data to do this intelligently. Best thing that I can find "out of the box" to do this is Windows Server "Distributed Filesystem Replication" which uses "Remote Differential Compression" -- After reading the background information on how this works, it actually looks like exactly what I need. Problem: Both servers are running Linux. D'oh! One approach to this I'm looking at is this, say it's 5AM and the cron job finishes: New Version.5 folder arrives at on local server SSH to remote server and copy Version.4 to Version.5 Run rsync on the local server pushing changes to the remote server. Rsync finally knows to do a differential copy between Version.4 and Version.5 Is there a smarter way to replicate Samba shares as close to real-time as possible? Anything out there that does "Remote Differential Compression" on Linux?

• why does the gingerbread emulator orientation gets stuck in apps?

  - by tabjsina

  At first I thought this was a problem with my app, but it seems to be happening in any app (though interestingly, not the home screen) in the gingerbread emulator. To replicate my issue, open eclipse and fire up the android emulator for gingerbread (I'm using the "Google APIs - API Level 9" as my target) So the procedure to duplicate once the emulator loads is press LCtrl-F11 to shift orientation to landscape, then again to switch to portrait Result: In the homescreen: The view rotates to landscape, and then back to portrait, as expected In any app (i've tried browser, calculator, maps, and the app i'm currently working on): the view rotates to landscape, and then nothing, it stays in landscape even the emulator is displaying the phone in landscape mode (see below) http://i54.tinypic.com/2ake06v.jpg Has anyone else had this issue, or have I installed the emulator in some incorrect way - this hasn't been an issue with any of the previous emulators

• SQL Express 2008 R2 on Amazon EC2 instance: tons of free memory, poor performance

  - by gravyface

  The old SQL Express 2005 was running on a low-end single Xeon CPU Dell server, RAID 5 7200 disks, 2 GB RAM (SBS 2003). I have not done any baseline measurements on the old physical server, but the Web app is used by half a dozen people (maybe 2 concurrently), so I figured "how bad can an Amazon EC2 instance be?". It's pretty horrible: a difference of 8 seconds of load time on one screen. First of all, I'm not a SQL guru, but here's what I've tried: Had a Small Instance, now running a c1.medium (High Cpu Medium) Windows 2008 32-bit R2 EBS-backed instance running IIS 7.5 and SQL Express 2008 R2. No noticeable improvement. Changed Page File from fixed 256 to Automatic. Setup a Striped Mirror from within Disk Management with two attached 1 GB EBS volumes. Moved database and transaction log, left everything else on the boot EBS volume. No noticeable change. Looked at memory, ~1000 MB of physical memory free (1.7 GB total). Changed SQL instance to use a minimum of 1024 RAM; restarted server, no change in memory usage. SQL still only using ~28MB of RAM(!). So I'm thinking: this database is tiny (28MB), why isn't the whole thing cached in RAM? Surely that would speed up performance. The transaction log is 241 MB. Seems kind of large in comparison -- has this not been committed? Is it a cause of performance degradation? I recall something about Recovery Models and log sizes somewhere in my travels, but not positive. Another thing: the old server was running SQL Express 2005. Not sure if that has any impact, but I tried changing the compatibility level from SQL 2000 to 2008, but that had no effect. Anyways, what else can I try here? Seems ridiculous to throw more virtual hardware at this thing. I know I/O is going to be rough on EBS volumes, but surely others are successfully running small .NET/SQL apps on reasonably priced instances?

• Cure for puzzle piece programming habbits?

  - by Recursion

  Even though I went to a decent CS school, I was still taught with the mentality of programming with puzzle pieces. By puzzle pieces I mean, looking up code segments at each step of the development process and adding them together as needed. Eventually gathering all of the pieces and having a properly working program. So as an example, if in my program the next step is to tokenize a string, I go to google and search "how do I tokenize a string in language". All instead of critically thinking about its implementation. I personally don't think its a very good way to program and I always seem to forget everything that I have searched for. So how can I get out of this puzzle piece mode of programmer that I was taught.

• Hard drive randomly sppeeding up

  - by Glenn Taylor

  Having a weird issue with my hard drive. Running Windows 7 with an I5 processor. At random times the hard drive will start running at top speed and gradually return to normal over the next two minutes or so. Going to Resource Monitor it shows a variety of things with high read or write numbers. Log files NTFS volume log, Windows prefetch, System/user/appdata, and Program data Norton are the usual top ones listed. This just started about three months ago although the computer is about 3 years old. Have run in safe mode with internet over the weekend going to all of my usual sites with no such speed up. Question 1 - what can be causing this? Question 2 - how can I find out where data is being sent(especially if over the net)? Thank you.

• Write set of integers to std::ofstream and be able to read them back

  - by bndu

  Hello, I need to write a bunch of unsigned integers to std::ofstream in binary mode: std::ofstream f; f.open("some path", std::ios::out | std::ios::binary); // some loop { unsigned int k = get_k(); // may product numbers from 0 to 65535 f << k; } f.close(); They are written to the output file "as is" w/o any delimiter. So when I'm trying to read them back (expecting to get what I wrote) using std::ifstream I get very strange values. What I'm doing wrong? Or I should to put ' ' (space) to the stream after any added number to separate them? Thanks.
