R: including model specifications in xtable(anova(...))

- by HamiltonUlmer

Hello R comrades: I have a bunch of loglinear models, which, for our purposes will just be glm() objects called mx, my, mz. I want to get a nicely-formatted xtable of the analysis of deviance, so naturally I would want to perform xtable(anova(mx, my, mz, test = "Chisq")). The vanilla output of xtable, however, doesn't include the model specifications. I'd like to include those for all the ANOVA tests I'm running, so if there is not a param I'm missing that does this I'll probably just have to hack up my own solution. But looking over the help page, there doesn't seem to be an easy way to include the model specifications. Any thoughts? Alternatives? If it helps this was done in 2.9.1 with xtable 1.5-5.

Screen capture during testing

- by Edwward

This is an application for reviewing performance tests. Simple in concept, tricky to describe. Picture: 1) Recording interactions with a WPF program so the inputs can be played back. 2) Playing the inputs back while doing a continuous screen capture. 3) Capturing wall time as well as continuous CPU percentages during playback. 4) Repeating steps (2) and (3) lots of times. 5) Writing the relevant stuff out to files/db. 6) Reading it and putting it all in a fancy UI for easy review/analysis. The killer for me is (2). I could use some guidance on a good, possibly commercial, screen capture SDK. I would also welcome the news that my whole problem already has a solution. And of course any thoughts on the overall idea would also be great. Thanks. Ed

What's the best encoding for videos on the Zune?

- by Will

I've got videos I want to encode to put on the zune. Have the encoding software (using Expression Encoder), but I'm not sure about what I should transcode to. I used the settings built into EE for the Zune, but the sync software still shows these videos are being converted before sync. I already have to get these videos into an acceptable format, so encoding twice is a waste of time and space. What I'm looking for is a video codec, audio codec, bitrate, WxH, and anything else I need to encode a video so it goes straight from my disk onto my Zune without re-encoding.

Performance Overhead of Perf Event Subsystem in Linux Kernel

- by Bo Xiao

Performance counters for Linux are a new kernel-based subsystem that provide a framework for all things performance analysis. It covers hardware level (CPU/PMU, Performance Monitoring Unit) features and software features (software counters, tracepoints) as well. Since 2.6.33, the kernel provide 'perf_event_create_kernel_counter' kernel api for developers to create kernel counter to collect system runtime information. What I concern most is the performance impact on overall system when tracepoint/ftrace is enabled. There are no docs I can find about them. I was once told that ftrace was implemented by dynamically patching code, will it slow the system dramatically?

Have you switched from CodeIgniter to Kohana?

- by Eli

Hi All, I usually just work with straight PHP, but want to try MVC and see if a framework will really speed up development. After much waffling, analysis paralysis, and many dumb SO questions, I thought I had settled on CodeIgniter for my next PHP project. However, I am now seriously considering Kohana. Has anyone made the switch from CI to Kohana? If so, why? What's better about the actual code, libraries, etc? Edit: Hi All, I did end up going with Kohana. It's easy to use, but more importantly, it's easy NOT to use, since there are a lot of things I like to work with native PHP for. It's ridiculously extensible, well coded, and seems like it is beginning to pull out ahead of CI in a few things like putting views in views, passing subview data, etc. I am sure CI will catch up, but Kohana should be 3 steps ahead by then =o)

Context Menu for Browser to download file to specific folder

- by elcojon

There is this website which has customized audio files for me. I would like to save them in a special folder. Now I don't want to select the "special folder" each time in the file-chooser dialogue of my browser. I would rather prefer to have a custom entry in the context menu when I right-click the download link. This context-menu-entry should do the trick and download the file to the predefined "special folder". How would I start about that? I am using Safari and Chrome. So a solution in either browser is fine. To get into the context menu of the browser, what kind of programming do I need to do? Is it an extension, plugin, etc.? Thanks

fortran error I/O

- by jpcgandre

I get this error when compiling: forrtl: severe (256): unformatted I/O to unit open for formatted transfers, unit 27, file C:\Abaqus_JOBS\w.txt The error occurs in the beginning of the analysis. At the start, the file w.txt is created but is empty. The error may be related to the fact that I want to read from an empty file. My code is: OPEN(27, FILE = "C:/Abaqus_JOBS/w.txt", status = "UNKNOWN") READ(27, *, iostat=stat) w IF (stat .NE. 0) CALL del_file(27, stat) SUBROUTINE del_file(uFile, stat) IMPLICIT NONE INTEGER uFile, stat C If the unit is not open, stat will be non-zero CLOSE(unit=uFile, status='delete', iostat=stat) END SUBROUTINE Ref: Close multiple files If you agree with my opion about the cause of the error, is there a way to solve it? Thanks

Is my TFS2010 backup/restore hosed?

- by bwerks

Hi all, I recently set up a sandbox TFS to test TFS-specific features without interfering with the production TFS. I was happy I did this sooner than I thought--I hadn't been backing up the encryption key from SSRS and upon restoring the reporting databases, they remained inactive, requiring initialization that could only come from applying the encryption key. Said encryption key was lost when I nuked the partition after backing up the TFS databases. The only option I seemed to have is to delete the encrypted data. I'm fine with this, since there wasn't much in there to begin with, however once they're deleted I'm not quite sure how to configure TFS to recognize a new installation of these services while using the restored versions of everything else. Unfortunately, the TFS help file doesn't seem to account for this state though. Is there a way to essentially rebuild the reporting and analysis databases? Or are they gone forever?

to get columns from Excel files using Apache POI??

- by posdef

Hi, In order to do some statistical analysis I need to extract values in a column of an Excel sheet. I have been using the Apache POI package to read from Excel files, and it works fine when one needs to iterate over rows. However I couldn't find anything about getting columns neither in the API (link text) nor through google searching. As I need to get max and min values of different columns and generate random numbers using these values, so without picking up individual columns, the only other option is to iterate over rows and columns to get the values and compare one by one, which doesn't sound all that time-efficient. Any ideas on how to tackle this problem? Thanks,

application that could track amount of downloads

- by user23950

My ISP only limits me for downloading about 25gb a month. After exceeding the limit, my speed goes down by half for another month. And its really a pain. I'm real addicted on downloading stuff from the internet. My question is: Is there an application that can track the amount/size of downloads in a month. Is there a trick that I could use to fool the eyes of my ISP. If they say 25 Gb limit in a month. Does it include the webpages, manga streams, video & audio streams. Or just direct download and p2p.

Is there any way to see the contents of a device via windows media player/sync?

- by snorfys

I've got a sansa clip mp3 player and an htc touch pro 2 phone that I put music/audio books etc. on. Putting stuff on there is easy peasy I open media player 11, go to the sync tab at the right and drag media to it. The problem is seeing what's already on there and removing anything I no-longer want on there - I have no way to see that aside from browsing via explorer. Both devices move media around to specifc folders so it's a bit annoying. Is there any way to do what I need in media player or is there any other good and free alternatives that will?

Random List of millions of elements in Python Efficiently

- by eWizardII

Hello, I have read this answer potentially as the best way to randomize a list of strings in Python. I'm just wondering then if that's the most efficient way to do it because I have a list of about 30 million elements via the following code: import json from sets import Set from random import shuffle a = [] for i in range(0,193): json_data = open("C:/Twitter/user/user_" + str(i) + ".json") data = json.load(json_data) for j in range(0,len(data)): a.append(data[j]['su']) new = list(Set(a)) print "Cleaned length is: " + str(len(new)) ## Take Cleaned List and Randomize it for Analysis shuffle(new) If there is a more efficient way to do it, I'd greatly appreciate any advice on how to do it. Thanks,

Bitmap manipulation in C++ on Windows

- by Oliver

Hi, I have myself a handle to a bitmap, in C++, on Windows: HBITMAP hBitmap; On this image I want to do some Image Recognition, pattern analysis, that sort of thing. In my studies at University, I have done this in Matlab, it is quite easy to get at the individual pixels based on their position, but I have no idea how to do this in C++ under Windows - I haven't really been able to understand what I have read so far. I have seen some references to a nice looking Bitmap class that lets you setPixel() and getPixel() and that sort of thing, but I think this is with .net . How should I go about turning my HBITMAP into something I can play with easily? I need to be able to get at the RGBA information. Are there libraries that allow me to work with the data without having to learn about DCs and BitBlt and that sort of thing?

Extracting rightmost N bits of an integer

- by srandpersonia

In the yester Code Jam Qualification round http://code.google.com/codejam/contest/dashboard?c=433101#s=a&a=0 , there was a problem called Snapper Chain. From the contest analysis I came to know the problem requires bit twiddling stuff like extracting the rightmost N bits of an integer and checking if they all are 1. I saw a contestant's(Eireksten) code which performed the said operation like below: (((K&(1<<N)-1))==(1<<N)-1) I couldn't understand how this works. What is the use of -1 there in the comparison?. If somebody can explain this, it would be very much useful for us rookies. Also, Any tips on identifying this sort of problems would be much appreciated. I used a naive algorithm to solve this problem and ended up solving only the smaller data set.(It took heck of a time to compile the larger data set which is required to be submitted within 8 minutes.). Thanks in advance.

I also, reinstalled windows default sound drivers and IDT High Definition Audio drivers several times. No success! The final decision is: There is no sound from headphone jack in laptop. Any suggestions?

How to cleverly stop "while loop" (php)

- by user3735697

I'm having trouble with creating code that echoes a bunch of stuff that is corresponding to the mysql database row. It needs to keep creating the content until all rows are used and then stop. But for some reason the php file causes the browser to keep loading (it never ends). Any help would be appreciated!

Windows 7 started well and then installed graphic driver but the others (sound, touchpad) were not recognized by the operating system. What should I do? Edit from OP Sorry for writing here. I don't know why but my account is not associated with this post. First, I have Tiger CD but problem is neigher my Macbook, nor my Desktop PC can read the CD. I have downloaded Driver's from Apple (http://support.apple.com/kb/DL74) but it's not working. I mean, when I double click the exe file, It gets listed in process list int task manager but after 5 seconds, I disappears. But somehow, Windows recognized my audio device and installed its driver. Microphone is ok but red light is on.

Auto-connect Bluetooth headphones in Windows 7 64bit

- by CptSkippy

I have a pair of bluetooth headphones that I've successfully paired with my Windows 7 64bit machine and audio plays through them without a hitch. On the Device Stage under the properties of the headphones in troubleshooting it shows "last connected" as "currently connected" even if I power cycle the headphones or after a reboot of my computer. So the Windows bluetooth stack has no trouble finding them. The problem I have is that whenever the headphones reconnect to my pc they show up as disconnected in the Sound Settings and no sound is routed to them until I manually connect them. I have to go into Sound Settings, then from the Playback tab right click on the headphones and choose the Connect option. Is there a way to make the Sound Settings connect automatically whenever the headphones are available to Windows?

Practical Python-based visual programming environment?

- by Who8MyLunch

I am looking for a practical visual programming environment based on Python. My primary application is algorithm development for processing remote-sensing imagery. I was initially inspired by LabVIEW from National Instruments, but that is more geared towards laboratory measurements and simulations. I write a lot of prototype code in Python and do a lot of interactive analysis with IPython. Does there exist a visual framework where a "program" is represented by connected nodes which each read data, do some work, and output data to the next node? I would like to use Python to write the code residing in each node. So far the best I've seen is Orange http://www.ailab.si/orange/, but it does not have the ability to start/stop individual nodes.

RUP (Rational Unified Process)

- by tony

I have chosen to use the development method RUP (Rational Unified Process) in my project. This is a method I've never used before. I've also included some elements from Scrum in the development process. The question is what the requirement specifications should contain in a RUP-model? Is it functional and non-functional requirements? And what should be included in a technical analysis and security requirements for RUP? Can’t find any information. Notes about this would be helpful. Hope people with RUP experience can share some useful experiences

I have narrowed the offending hardware down to my: D-Link DWA-547 RangeBooster N650 Desktop Adapter If i disable it in the device manager everything runs fine and smooth. The card works, and gives me super fast internet. But the rest of the system hangs. I have tried installing the card with the drivers from the cd that came with it, i also tried the lates beta drivers from the d-link webpage, but the problem persists. What do i do? I am running windows 7 x64 on a asus p5b motherboard with 2 intel processors.

Java source code generation frameworks

- by Superfilin

I have a set of Java 5 source files with old-style Doclet tags, comments and annotations. And based on that I would like to write a generator for another set of Java classes. What is the best way to do that? And are there any good standalone libraries for code analysis/generation in Java? Any shared exprience in this field is appreciated. So, far I have found these: JaxME's Java Source Reflection - seems good, but it does not seem to support annotations. Also it had no release since 2006. Annogen - uses JDK's Doclet generator, which has some bugs under 1.5 JDK. Also it had no releases for a long time. Javaparser - seems good as well and pretty recent, but only supports Visitor pattern for a single class i.e. no query mechanism like in the 2 above packages.

How can I use splne() with ggplot?

- by David

I would like to fit my data using spline(y~x) but all of the examples that I can find use a spline with smoothing, e.g. lm(y~ns(x), df=_). I want to use spline() specifically because I am using this to do the analysis represented by the plot that I am making. Is there a simple way to use spline() in ggplot? I have considered the hackish approach of fitting a line using geom_smooth(aes(x=(spline(y~x)$x, y=spline(y~x)$y)) but I would prefer not to have to resort to this. Thanks!
