• How Does the Bing Search Engine Differ in Analyzing Pages Compared to Google?

  Finding what you need on the internet is much easier today than it used to be. With the biggest players dueling it out to get people to choose theirs over their competitors. People are very visual when it comes to just about everything, and Bing seems to be using that to its advantage. So, how does the Bing search engine differ in analyzing pages compared to Google?

• Sorting data in the SSIS Pipeline (Video)

  In this post I want to show a couple of ways to order the data that comes into the pipeline. a number of people have asked me about this primarily because there are a number of ways to do it but also because some components in the pipeline take sorted inputs. One of the methods I show is visually easy to understand and the other is less visual but potentially more performant.

• empty response body in ajax (or 206 Partial Content)

  - by Nikita Rybak

  Hi guys, I'm feeling completely stupid because I've spent two hours solving task which should be very simple and which I solved many times before. But now I'm not even sure in which direction to dig. I fail to fetch static content using ajax from local servers (Apache and Mongrel). I get responses 200 and 206 (depending on the server), empty response text (although Content-Length header is always correct), firebug shows request in red. Javascript is very generic, I'm getting same results even here: http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_first (just change document location to 'http://localhost:3000/whatever') So, it's probably not the cause. Well, now I'm out of ideas. I can also post http headers, if it'll help. Thanks!

• Explicit Type Conversion and Multiple Simple Type Specifiers

  - by James McNellis

  To value initialize an object of type T, one would do something along the lines of one of the following: T x = T(); T x((T())); My question concerns types specified by a combination of simple type specifiers, e.g., unsigned int: unsigned int x = unsigned int(); unsigned int x((unsigned int())); Visual C++ 2008 and Intel C++ Compiler 11.1 accept both of these without warnings; Comeau 4.3.10.1b2 and g++ 3.4.5 (which is, admittedly, not particularly recent) do not. According to the C++ standard (C++03 5.2.3/2, expr.type.conv): The expression T(), where T is a simple-type-specifier (7.1.5.2) for a non-array complete object type or the (possibly cv-qualified) void type, creates an rvalue of the specified type, which is value-initialized 7.1.5.2 says, "the simple type specifiers are," and follows with a list that includes unsigned and int. Therefore, given that in 5.2.3/2, "simple-type-specifier" is singular, and unsigned and int are two type specifiers, are the examples above that use unsigned int invalid? (and, if so, the followup is, is it incorrect for Microsoft and Intel to support said expressions?) This question is more out of curiosity than anything else; for all of the types specified by a combination of multiple simple type specifiers, value initialization is equivalent to zero initialization. (This question was prompted by comments in response to this answer to a question about initialization).

• How to setup matlabpool for multiple processors?

  - by JohnIdol

  I just setup a Extra Large Heavy Computation EC2 instance to throw it at my Genetic Algorithms problem, hoping to speed up things. This instance has 8 Intel Xeon processors (around 2.4Ghz each) and 7 Gigs of RAM. On my machine I have an Intel Core Duo, and matlab is able to work with my two cores just fine by runinng: matlabpool open 2 On the EC2 instance though, matlab only is capable of detecting 1 out of 8 processors, and if I try running: matlabpool open 8 I get an error saying that the ClusterSize is 1 since there's only 1 core on my CPU. True, there is only 1 core on each CPU, but I have 8 CPUs on the given EC2 instance! So the difference from my machine and the ec2 instance is that I have my 2 cores on a single processor locally, while the EC2 instance has 8 distinct processors. My question is, how do I get matlab to work with those 8 processors? I found this paper, but it seems related to setting up matlab with multiple EC2 instances (not related to multiple processors on the same instance, EC2 or not), which is not my problem. Any help appreciated!

• How do I test OpenCL on GPU when logged in remotely on Mac?

  - by Christopher Bruns

  My OpenCL program can find the GPU device when I am logged in at the console, but not when I am logged in remotely with ssh. Further, if I run the program as root in the ssh session, the program can find the GPU. The computer is a Snow Leopard Mac with a GeForce 9400 GPU. If I run the program (see below) from the console or as root, the output is as follows (notice the "GeForce 9400" line): 2 devices found Device #0 name = GeForce 9400 Device #1 name = Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz but if it is just me, over ssh, there is no GeForce 9400 entry: 1 devices found Device #0 name = Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz I would like to test my code on the GPU without having to be root. Is that possible? Simplified GPU finding program below: #include <stdio.h> #include <OpenCL/opencl.h> int main(int argc, char** argv) { char dname[500]; size_t namesize; cl_device_id devices[10]; cl_uint num_devices; int d; clGetDeviceIDs(0, CL_DEVICE_TYPE_ALL, 10, devices, &num_devices); printf("%d devices found\n", num_devices); for (d = 0; d < num_devices; ++d) { clGetDeviceInfo(devices[d], CL_DEVICE_NAME, 500, dname, &namesize); printf("Device #%d name = %s\n", d, dname); } return 0; } EDIT: I found essentially the same question being asked on nvidia's forums. Unfortunately, the only answer was of the form "this is the wrong forum".

• SQLite self-join performance

  - by Derk

  What I essentially want, is to retreive all features and values of products which have a particular feature and value. For example: I want to know all available hard drive sizes of products that have an Intel processor. I have three tables: product_to_value (product_id, feature_id, value_id) features (id, value) // for example Processor family, Storage size, etc. values (id, value) // for example Intel, 60GB, etc The simplified query I have now: SELECT features.name, featurevalues.name, featurevalues.value FROM products, products as prod2, features, features as feat2, values, values as val2 WHERE products.feature = features.id AND products.value = values.id AND products.product = prod2.product AND prod2.feature_id = feat2.id AND prod2.value_id = val2.id AND features.id = ? AND feat2.id = ? All columns have an index. I am using SQLite. The problem is that it's very slow (70ms per query, without the self-join it's <1ms). Is there a smarter way to fetch data like this? Or is this too much to ask from SQLite? I personally think I am simply overlooking something, as I am quite new to SQLite.

• Problems using a library in Xcode

  - by Pablo

  Hi! I'm actually developping an application for iPhone and I need to use a library, initially dedicated to a Linux environment. Since I'm using a Mac (with Snow Leopard and Intel Core Duo), I guess it's possible to use this library in my app. My library has 3 files: a file .h, a file .a and a file .so (both .a and .so are in /Developer/usr/lib). In addition I have included the .h i nmy code and I've added the .a in XCode has a framework (and it works because XCode find the .so compiling). For your info when I use the command "file" for the file .so, I have: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, not stripped When I compile for the Xcode Simulator, I have a warning and an error. The warning is: In /Developer/usr/lib/mylib.so, file was built for unsupported file format which is not the architecture being linked (i386) The error is: "_mylib_fct", referenced from: -[MyAppAppDelegate applicationDidBecomeActive:] in MyAppAppDelegate.o Symbol(s) not found Collect2: ld returned 1 exit status When I compile for the Device 3.0 with architecture arm6, I also have the same error, but the warning is quite different: ln /Users/Pablo/MyApp/mylib.a file is not of required architecture I try to solve this and make the app working with this lib since days, and I don't understand why the compiler is complaining... is it a 32/64 bits issues ? How can I deal with that ? Your help will be very appreciated. Thx!

• Building a python module and linking it against a MacOSX framework

  - by madflo

  I'm trying to build a Python extension on MacOSX 10.6 and to link it against several frameworks (i386 only). I made a setup.py file, using distutils and the Extension object. I order to link against my frameworks, my LDFLAGS env var should look like : LDFLAGS = -lc -arch i386 -framework fwk1 -framework fwk2 As I did not find any 'framework' keyword in the Extension module documentation, I used the extra_link_args keyword instead. Extension('test', define_macros = [('MAJOR_VERSION', '1'), ,('MINOR_VERSION', '0')], include_dirs = ['/usr/local/include', 'include/', 'include/vitale'], extra_link_args = ['-arch i386', '-framework fwk1', '-framework fwk2'], sources = "testmodule.cpp", language = 'c++' ) Everything is compiling and linking fine. If I remove the -framework line from the extra_link_args, my linker fails, as expected. Here is the last two lines produced by a python setup.py build : /usr/bin/g++-4.2 -arch x86_64 -arch i386 -isysroot / -L/opt/local/lib -arch x86_64 -arch i386 -bundle -undefined dynamic_lookup build/temp.macosx-10.6-intel-2.6/testmodule.o -o build/lib.macosx-10.6-intel-2.6/test.so -arch i386 -framework sgdosx -framework srtosx -framework ssvosx -framework stsosx Unfortunately, the .so that I just produced is unable to find several symbols provided by this framework. I tried to check the linked framework with otool. None of them is appearing. $ otool -L test.so test.so: /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1) There is the output of otool run on a test binary, made with g++ and ldd using the LDFLAGS described at the top of my post. On this example, the -framework did work. $ otool -L vitaosx vitaosx: /Library/Frameworks/sgdosx.framework/Versions/A/sgdosx (compatibility version 1.0.0, current version 1.0.0) /Library/Frameworks/ssvosx.framework/Versions/A/ssvosx (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1) May this issue be linked to the "-undefined dynamic_lookup" flag on the linking step ? I'm a little bit confused by the few lines of documentation that I'm finding on Google. Cheers,

• Is it possible that a single-threaded program is executed simultaneously on more than one CPU core?

  - by Wolfgang Plaschg

  When I run a single-threaded program that i have written on my quad core Intel i can see in the Windows Task Manager that actually all four cores of my CPU are more or less active. One core is more active than the other three, but there is also activity on those. There's no other program (besided the OS kernel of course) running that would be plausible for that activitiy. And when I close my program all activity an all cores drops down to nearly zero. All is left is a little "noise" on the cores, so I'm pretty sure all the visible activity comes directly or indirectly (like invoking system routines) from my program. Is it possible that the OS or the cores themselves try to balance some code or execution on all four cores, even it's not a multithreaded program? Do you have any links that documents this technique? Some infos to the program: It's a console app written in Qt, the Task Manager states that only one thread is running. Maybe Qt uses threads, but I don't use signals or slots, nor any GUI. Link to Task Manager screenshot: http://img97.imageshack.us/img97/6403/taskmanager.png This question is language agnostic and not tied to Qt/C++, i just want to know if Windows or Intel do to balance also single-threaded code on all cores. If they do, how does this technique work? All I can think of is, that kernel routines like reading from disk etc. is scheduled on all cores, but this won't improve performance significantly since the code still has to run synchronous to the kernel api calls. EDIT Do you know any tools to do a better analysis of single and/or multi-threaded programs than the poor Windows Task Manager?

• Performance of java on different hardware?

  - by tangens

  In another SO question I asked why my java programs run faster on AMD than on Intel machines. But it seems that I'm the only one who has observed this. Now I would like to invite you to share the numbers of your local java performance with the SO community. I observed a big performance difference when watching the startup of JBoss on different hardware, so I set this program as the base for this comparison. For participation please download JBoss 5.1.0.GA and run: jboss-5.1.0.GA/bin/run.sh (or run.bat) This starts a standard configuration of JBoss without any extra applications. Then look for the last line of the start procedure which looks like this: [ServerImpl] JBoss (Microcontainer) [5.1.0.GA (build: SVNTag=JBoss_5_1_0_GA date=200905221634)] Started in 25s:264ms Please repeat this procedure until the printed time is somewhat stable and post this line together with some comments on your hardware (I used cpu-z to get the infos) and operating system like this: java version: 1.6.0_13 OS: Windows XP Board: ASUS M4A78T-E Processor: AMD Phenom II X3 720, 2.8 GHz RAM: 2*2 GB DDR3 (labeled 1333 MHz) GPU: NVIDIA GeForce 9400 GT disc: Seagate 1.5 TB (ST31500341AS) Use your votes to bring the fastest configuration to the top. I'm very curious about the results. EDIT: Up to now only a few members have shared their results. I'd really be interested in the results obtained with some other architectures. If someone works with a MAC (desktop) or runs an Intel i7 with less than 3 GHz, please once start JBoss and share your results. It will only take a few minutes.

• Execute less compiler anywhere on the computer

  - by Xenioz

  I'm having a little problem with executing *.cmd files so I can execute them anywhere on the computer with cmd. What I exactly want is to execute the less.cmd file, which support optional arguments and uses lessc.wsf (Less.js compiler for Windows Script Host) for converting less css to pure css. The less.cmd contains: ::For convenience @cscript //nologo "%~dp0lessc.wsf" %* What I've done so far: added absolute path to lessc.cmd to the PATH system variable and moved .cmd in the PATHTEXT system variable to the beginning. Also did this: From a command prompt; assoc .bat should return with ..bat=batfile If not assoc .bat=batfile to restore the default file type association. ftype batfile should return with batfile="%1" %* If not ftype batfile="%1" %* to restore the default "Open" action for the file type. This still doesn't work unless I approach the cmd file with a absolute path in cmd, if I enter lessc anywhere else then I get C:\Intel Intel is not recognized as an internal or external command, operable program or batch file. , I've restarted my computer more than once to be sure changes will take effect. I hope somebody has the answer.

• Drawing an image in Java, slow as hell on a netbook.

  - by Norswap

  In follow-up to my previous questions (especially this one : http://stackoverflow.com/questions/2684123/java-volatileimage-slower-than-bufferedimage), i have noticed that simply drawing an Image (it doesn't matter if it's buffered or volatile, since the computer has no accelerated memory*, and tests shows it's doesn't change anything), tends to be very long. (*) System.out.println(GraphicsEnvironment.getLocalGraphicsEnvironment() .getDefaultScreenDevice().getAvailableAcceleratedMemory()); --> 0 How long ? For a 500x400 image, about 0.04 seconds. This is only drawing the image on the backbuffer (obtained via buffer strategy). Now considering that world of warcraft runs on that netbook (tough it is quite laggy) and that online java games seems to have no problem whatsoever, this is quite thought provoking. I'm quite certain I didn't miss something obvious, I've searched extensively the web, but nothing will do. So do any of you java whiz have an idea of what obscure problem might be causing this (or maybe it is normal, tough I doubt it) ? PS : As I'm writing this I realized this might be cause by my Linux installation (archlinux) tough I have the correct Intel driver. But my computer normally has "Integrated Intel Graphics Media Accelerator 950", which would mean it should have accelerated video memory somehow. Any ideas about this side of things ?

• Creative Gesture Camera in Processing

  - by user2892963

  I'm trying to use the creative gesture camera in Processing. I started with the Intel Perceptual Computing SDK, and ran into an issue. I want to get the hand openness, and I am running into some issues - no matter what, the hand.openness returns 0. It otherwise runs quite well... Some Sample code I'm trying to get to work: If you open your hand it starts printing to the console, close it and it stops. import intel.pcsdk.*; PXCUPipeline session; PXCMGesture.GeoNode hand = new PXCMGesture.GeoNode(); void setup() { session = new PXCUPipeline(this); if(!session.Init(PXCUPipeline.GESTURE)) exit(); } void draw() { background(0); if(session.AcquireFrame(false)) { if(session.QueryGeoNode(PXCMGesture.GeoNode.LABEL_BODY_HAND_PRIMARY|PXCMGesture.GeoNode.LABEL_OPEN, hand)) //Only when primary hand is open { rect(0, 0, 10, 10); println(hand.openness + " : " + frameCount); //Openness should be from 0 to 100 } session.ReleaseFrame(); } } Using the current version of Processing (2.0.3), Perceptual Computing SDK Version 7383.

• C Population Count of unsigned 64-bit integer with a maximum value of 15

  - by BitTwiddler1011

  I use a population count (hamming weight) function intensively in a windows c application and have to optimize it as much as possible in order to boost performance. More than half the cases where I use the function I only need to know the value to a maximum of 15. The software will run on a wide range of processors, both old and new. I already make use of the POPCNT instruction when Intel's SSE4.2 or AMD's SSE4a is present, but would like to optimize the software implementation (used as a fall back if no SSE4 is present) as much as possible. Currently I have the following software implementation of the function: inline int population_count64(unsigned __int64 w) { w -= (w 1) & 0x5555555555555555ULL; w = (w & 0x3333333333333333ULL) + ((w 2) & 0x3333333333333333ULL); w = (w + (w 4)) & 0x0f0f0f0f0f0f0f0fULL; return int(w * 0x0101010101010101ULL) 56; } So to summarize: (1) I would like to know if it is possible to optimize this for the case when I only want to know the value to a maximum of 15. (2) Is there a faster software implementation (for both Intel and AMD CPU's) than the function above?

• Problem with Email Notifications in VisualSVN Server

  - by emzero

  Hey guys! I have a dedicated server running windows 2003 server and Visual SVN Server 2.0.8. I'm trying to configure it to send email notifications on commit. So I found this article on Visual SVN site. It says I have to edit the Post-commit hook and set it to the following: "%VISUALSVN_SERVER%\bin\VisualSVNServerHooks.exe" ^ commit-notification "%1" -r %2 ^ --from <from-email> --to <to-email> ^ --smtp-server <smtp-server> Of course I've replaced the variables there. The problem is when someone commits something, the svn client throws the following error: post-commit hook failed (exit code 1) with no output. The commit process runs with no problems, I mean it does commit the files. But it won't send any email notification. If I remove the post-commit hook, then I don't get the error (and of course I don't get any notification). Could you help me out with it? The error doesn't tell too much =S Thank you!

• i5 540M or i7 720QM for laptop running VMs and software development tools?

  - by Donald Hughes

  I'm a software developer that would primarily be running Windows 7 as the primary operating system. On a typical day, I might, at any given moment, be running Visual Studio, Expression Web, SQL Server developer (and Management Console), IIS, Photoshop, a dozen browser tabs in 2-3 different browsers, Skype video chat, streaming music, and a couple of VMs (WinXP and Ubuntu) for testing/experimentation. Obviously, RAM is a concern, which is why I plan to use 8 GB so I can devote enough to the VMs to be usable. I'm also tempted to use an ExpressCard SSD for storing the VM disks to ease disk contention. And I know that that is asking a lot from a laptop, and I should just use a desktop, but I need to be able to take my work with me between several locations. It seems that at a reasonable price point, it comes down to the i5 540M versus the i7 720QM. I'm leaning toward the i7 since it would allow me to dedicate a whole hyperthreaded core to each VM, and still have two cores left for the primary OS. I've heard that the i5 has better battery life, but I'm curious for my scenario if there would be a meaningful difference. I don't usually work without a plug, but I do occasionally ride the train or fly and it would be nice to have at least 3 hours of juice for unusual circumstances. And, finally, for this usage scenario, would a dedicated video option be preferred over the i5's integrated video? It sounds like Visual Studio 2010 (and Windows 7) can take advantage of the video card.
