  • Unable to reserve a job with beanstalkd

    - by Brian Hogg
    I have tried on two different servers to get beanstalkd up and running and do a couple tests (locally on MacOSX compiled from source, and on a CentOS server installed with yum) I can get the server running either with sudo beanstalkd -d -p 11300 or sudo beanstalkd -p 11300 & I then tried using the php lib and it just froze. Connecting directly: telnet localhost 11300 I do the following to mimic the PHP test script: use foo USING foo put 0 0 120 5 hello INSERTED 1 reserve-with-timeout 0 TIMED_OUT If I just run reserve It's stuck indefinitely. Any ideas?

  • In LaTeX, how can one add a header/footer in the document class Letter?

    - by Brian M. Hunt
    In LaTeX, how can one create a document using the Letter documentclass, but with customized headers and footers? Typically I would use: \usepackage{fancyhdr} \pagestyle{fancy} \lhead{\footnotesize \parbox{11cm}{Custom left-head-note} } \lfoot{\footnotesize \parbox{11cm}{\textit{#2}}} \rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}} \renewcommand\headheight{24pt} \renewcommand\footrulewidth{0.4pt} However, with \documentclass{letter}, this doesn't work at all. Suggestions are duly appreciated. EDIT: Here is sample code that doesn't work (for any apparent reason): \documentclass[12pt]{letter} \usepackage{fontspec}% font selecting commands \usepackage{xunicode}% unicode character macros \usepackage{xltxtra} % some fixes/extras % page counting, header/footer \usepackage{fancyhdr} \usepackage{lastpage} \pagestyle{fancy} \lhead{\footnotesize \parbox{11cm}{Draft 1} } \lfoot{\footnotesize \parbox{11cm}{\textit{2}}} \cfoot{} \rhead{\footnotesize 3} \rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}} \renewcommand{\headheight}{24pt} \renewcommand{\footrulewidth}{0.4pt} \begin{document} \name{ Joe Laroo } \signature{ Joe Laroo } \begin{letter}{ To-Address } \renewcommand{\today}{ February 16, 2009 } \opening{ Opening } Content of the letter. \closing{ Yours truly, } \end{letter} \end{document}

  • iPad launch orientation

    - by Brian
    After reading many posts, I still haven't got a clue how to solve this problem... The first view of my app is a tableViewController. I override (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation and it always returns YES. If I hold my iPad upright under landscape orientation, it rotates right after I launch the app. However, if I put my iPad flat on the table, even though my homepage is in landscape orientation, it launches in protrait orientation. So I guess the problem is, how can I get the orientation of my homepage and launch my app with that orientation?

  • Is there a version of the removeElement function in Go for the vector package like Java has in its V

    - by Brian T Hannan
    I am porting over some Java code into Google's Go language and I converting all code except I am stuck on just one part after an amazingly smooth port. My Go code looks like this and the section I am talking about is commented out: func main() { var puzzleHistory * vector.Vector; puzzleHistory = vector.New(0); var puzzle PegPuzzle; puzzle.InitPegPuzzle(3,2); puzzleHistory.Push(puzzle); var copyPuzzle PegPuzzle; var currentPuzzle PegPuzzle; currentPuzzle = puzzleHistory.At(0).(PegPuzzle); isDone := false; for !isDone { currentPuzzle = puzzleHistory.At(0).(PegPuzzle); currentPuzzle.findAllValidMoves(); for i := 0; i < currentPuzzle.validMoves.Len(); i++ { copyPuzzle.NewPegPuzzle(currentPuzzle.holes, currentPuzzle.movesAlreadyDone); copyPuzzle.doMove(currentPuzzle.validMoves.At(i).(Move)); // There is no function in Go's Vector that will remove an element like Java's Vector //puzzleHistory.removeElement(currentPuzzle); copyPuzzle.findAllValidMoves(); if copyPuzzle.validMoves.Len() != 0 { puzzleHistory.Push(copyPuzzle); } if copyPuzzle.isSolutionPuzzle() { fmt.Printf("Puzzle Solved"); copyPuzzle.show(); isDone = true; } } } } If there is no version available, which I believe there isn't ... does anyone know how I would go about implementing such a thing on my own?

  • How do I overwrite a file currently being read by Python

    - by Brian
    Hi guys, I am not too sure the best way to word this, but what I want to do, is read a pdf file, make various modifications, and save the modified pdf over the original file. As of now, I am able to save the modified pdf to a separate file, but I am looking to replace the original, not create a new file. Here is my current code: from pyPdf import PdfFileWriter, PdfFileReader output = PdfFileWriter() input = PdfFileReader(file('input.pdf', 'rb')) blank = PdfFileReader(file('C:\\BLANK.pdf', 'rb')) # Copy the input pdf to the output. for page in range(int(input.getNumPages())): output.addPage(input.getPage(page)) # Add a blank page if needed. if (input.getNumPages() % 2 != 0): output.addPage(blank.getPage(0)) # Write the output to pdf. outputStream = file('input.pdf', 'wb') output.write(outputStream) outputStream.close() If i change the outputStream to a different file name, it works fine, I just cant save over the input file because it is still being used. I have tried to .close() the stream, but it was giving me errors as well. I have a feeling this has a fairly simple solution, I just haven't had any luck finding it. Thanks!

  • A Question About Embedding HTML In PHP

    - by Brian
    Hello all Some time ago I read a posting on a board where the person was talking poorly about people that have HTML embedded/within their PHP. I do quite a bit of PHP development but I still interleave HTML and PHP in the same document. Is there a better way to do this, am I doing it wrong? I know that in JSP/JSF they use an XML document with namespaces to insert their HTML code so I was wondering if there was a similar function that PHP uses that I should be taking advantage of. Thanks for taking the time to read. :-)

  • why doesn't winmain set the errorlevel?

    - by Brian R. Bondy
    int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { MessageBox(NULL, _T("This should return 90 no?"), _T("OK"), MB_OK); return 90; } Why does the above program correctly display the message box, but does not set the error level? I compile this program to the name a.exe. Then from command prompt I type: c:\> a.exe (message box is displayed, I press ok) c:\> echo %ERRORLEVEL% 0 I get the same results if I do exit(90); right before the return. It still says 0. I also tried to start the program via CreateProcess and obtain the result with GetExitCodeProcess but it also returns 0 to me. I did error checking to ensure it was all started correctly. I originally seen this problem in a more complex program. But made this simple program to verify the problem. Results are the same, both programs that have WinMain return 0 always. I tried both x64, x86 and unicode and MBCS compiling options. All give 0 as an error level/status code.

  • Simple way to use Foreign Key values for sorting?

    - by Brian Rizzo
    Disclaimer: I jumped to C# 2008 recently and SubSonic 3 (3.0.0.4) at the same time. I haven't used Linq for much of anything in the past. Is there an easy way to use the foreign key display value for sorting, rather than the FK Id (which is numeric)? I've added a new Find method in my ActiveRecord.tt to help with sorting based on a string field name but after doing some testing I realized that even though its working as it should be, I am not handling foreign key fields at all (they are just sorting by their value). Even if I need to change how I am accessing the data it is early enough in the project to do that. Just looking for suggestions.

  • Does Eclipse Ganymede have a mouse-click bug in the Navigator view?

    - by Brian Deacon
    I've had to downgrade from Galileo to Ganymede in order to use the version of the FlexBuilder plugin that we are licensed for. Since the downgrade, I have several times accidentally dragged files or entire folders from one part of my project into another (or even into another project). I blamed this on fatfingers the first couple times, but I just now watched it do it to me on what I definitely know to have been a single left click on the folder that the file ended up moving to. Does anybody know if this is a known issue with Ganymede?

  • Python 2D list has weird behavor when trying to modify a single value...

    - by Brian
    Hi guys, So I am relatively new to Python and I am having trouble working with 2D Lists. Here's my code: data = [[None]*5]*5 data[0][0] = 'Cell A1' print data and here is the output (formatted for readability): [['Cell A1', None, None, None, None], ['Cell A1', None, None, None, None], ['Cell A1', None, None, None, None], ['Cell A1', None, None, None, None], ['Cell A1', None, None, None, None]] Why does every row get assigned the value?

  • SED: Matching on 2 patterns on the same line

    - by Brian Knott
    Hi I want to delete a line using sed if it matches 2 regular expressions in the same line. EG the line starts with /* and end with */ (comment). The following script will do most of that. sed -e '/^\/*/ d' -e '/*\/$/ d' filename This script will remove all lines that start with * and end with */. I want it to remove the line only if is meets both criteria not one.

  • Collection wrapping a array is read-only. Possible to make it writeable without casting?

    - by Brian Triplett
    I have a Collection<T> property that wraps a array like T[] array; public Collection<T> Items { get { return new Collection<T>(array); } } When I attempt to assign to the collection via: T variable; Items[i] = variable; I get a NotSupportedException because the colleciton's IsReadOnly property is true. Turns out that this is a design choice by Microsoft. Does anyone know a workaround that does NOT involve enumeration? It could be done if the underlying data is not an array but I enjoy the performance gains because the data is fixed length.

  • What are good educational resources for setting up .Net Webservice on a DMZ connecting to SQL Server

    - by Brian
    We are going to begin implementing a web service that will be hosted on a DMZ server. This web server will post data to a SQL server and we're trying to determine the best methodology to handle this. Things that concern us are web service authentication, SOAP, and whether or not to store the database on the DMZ or the local network. This same scenario will apply to ASP.Net apps. Trust me, I've already searched the web, but as usual, the online resources I've found either talk about just authentication, or just about SOAP, or etc, but does not show or suggest how the entire system can work together. Can you give me a list of resources such as links that I've missed, books, classes, or etc that would help? Thank You.

  • Java - Creating a Compiler Help

    - by Brian
    So for my programming class we have had a project to create a virtual machine including a memory unit, cpu, Input, Output, Instruction Register, Program Counter, MAR, MDR and so on. Now we need to create a compiler using Java Code that will take a .exe file written in some txt editor and convert it to java byte code and run the code. The code we will be writing in the .exe file is machine code along the lines of: IN X IN Y ADD X STO Y OUT Y STOP DC X 0 DC Y 0 I am just a beginner and only have 2 days to write this and am very lost and have no idea where to start....Any Help will be much appreciated. Thanks

  • Should you remove all warnings in your Verilog or VHDL design? Why or why not?

    - by Brian Carlton
    In (regular) software I have worked at companies where the gcc option -Wall is used to show all warnings. Then they need to be dealt with. With non-trivial FPGA/ASIC design in Verilog or VHDL there are often many many warnings. Should I worry about all of them? Do you have any specific techniques to suggest? My flow is mainly for FPGAs (Altera and Xilinx in particular), but I assume the same rules would apply to ASIC design, possibly more so due to the inability to change the design after it is built.

  • Xml files stop being served by IIS6 after allowing .net to process the .xml extension

    - by Brian Surowiec
    I added a route into my site to allow for a sitemap and everything worked fine in IIS7 but once I deployed the route stopped working. Since the live server is running IIS6 I needed to put a new mapping in for .xml to be processed by .net and then it started to work. My issue though is on every other xml file on the site now. I keep getting a 404 error when trying to view xml files, but the sitemap.xml route works. Is this a routing issue or an IIS setup issue? Here are my routes if it will help routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Gallery-Group-View", "Projects/{groupId}", new { controller = "Gallery", action = "GalleryList", groupId = "" }); routes.MapRoute( "Gallery-List-View", "Projects/{groupId}/{galleryId}", new { controller = "Gallery", action = "GalleryView", groupId = "", galleryId = "" }); routes.MapRoute( "Sitemap", "Sitemap.xml", new { controller = "XML", action = "Sitemap" } ); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } );

  • Self updating application install with WIX?

    - by Brian ONeil
    I am writing an application that needs to be installed on a large number of desktops and also needs to update itself. We are looking at WIX for creating the installation. I have used ClickOnce and it is not a good solution for this install. WIX seems to fit, but there is no good process for auto update that I have found. I have looked at ClickThrough, but it doesn't seem ready for prime time yet. Does anyone have another good solution to use with WIX (or maybe another install program) to auto update an application install?

  • CDI timeout results in an NPE

    Is there a way (in JSF 2) to catch a Conversation timeout and redirect a user to a new page? I'm getting nasty NullPointerExceptions when the conversation times out. I could redirect the user on all NPE's, but that seems like too big a net.

  • What would make offsetParent null?

    - by Brian Ramsay
    I am trying to do positioning in JavaScript. I am using a cumulative position function based on the classic quirksmode function that sums offsetTop and offsetLeft for each offsetParent until the top node. However, I am running into an issue where the element I'm interested in has no offsetParent in Firefox. In IE offsetParent exists, but offsetTop and offsetLeft all sum up to 0, so it has the same problem in effect as in Firefox. What would cause an element that is clearly visible and usable on the screen to not have an offsetParent? Or, more practically, how can I find the position of this element in order to place a drop-down beneath it?

  • Display message when user leaves site

    - by Brian Rasmusson
    Hi, I'm looking for a way to display a message to the user if he leaves my site after only viewing one page. I found this (http://www.pgrs.net/2008/1/30/popup-when-leaving-website) clever solution, but it has a few flaws: staying_in_site = false; Event.observe(document.body, 'click', function(event) { if (Event.element(event).tagName == 'A') { staying_in_site = true; } }); window.onunload = popup; function popup() { if(staying_in_site) { return; } alert('I see you are leaving the site'); } It displays the message also when refreshing the page or using the back button. Do you know a better solution or how to fix it in the above code? I'm no javascript master :) My intention is to add the code on very specific landing pages only, and display the message when people leave the page without downloading my trial software or reading other pages on my site.

  • Design patterns to avoid

    - by Brian Rasmussen
    A lot of people seem to agree, that the Singleton pattern has a number of drawbacks and some even suggest to avoid the pattern all together. There's an excellent discussion here. Please direct any comments about the Singleton pattern to that question. Are there other design patterns, that should be avoided or used with great care?
