  • 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?

  • How to package up a Python 3 script with modules

    - by Brian
    I created a small script that uses a few 3rd-party modules. I'm not sure how to distribute it. I tried Pyinstaller, but that doesn't seem to work. It can't find the modules. When I give the binary to a co-worker, it says it is looking for files in my home directory ( not his ) and dies. I have found that Pyinstaller is not able to find most modules. I am running Python 3 and installed Pyinstaller with pip from Python 2. It did not work trying to use pip from Python 3. When, I give it a path to my modules, it complains that they are python 3 modules. Just looking for some clarification. Ultimately, I'd like to run this on a linux or OS X box where python and my modules probably won't be installed. I just started Python yesterday and have a ton to learn.

  • 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

  • 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?

  • 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?

  • MySQL Select names with last names starting with certain letter

    - by Brian
    I have a MySQL database with a field Name which contains full names. To select all people with last names starting with a particular letter, let's say A for this example, I use the following query: SELECT * FROM db WHERE Name LIKE '% A%'. However, this also selects users who have a middle name starting with A. Is there anyway to alter this query so that only a last name starting in A will be selected?

  • 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.

  • C++ smart pointer for a non-object type?

    - by Brian
    Hi, I'm trying to use smart pointers such as auto_ptr, shared_ptr. However, I don't know how to use it in this situation. CvMemStorage *storage = cvCreateMemStorage(); ... use the pointer ... cvReleaseMemStorage(&storage); I'm not sure, but I think that the storage variable is just a malloc'ed memory, not a C++ class object. Is there a way to use the smart pointers for the storage variable? Thank you.

  • 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?

  • 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?

  • 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.

  • Access report not showing data

    - by Brian Smith
    I have two queries that I am using to generate a report from, the problem is when I run the report, three fields do not show any data at all for some reason. Query 1: SELECT ClientSummary.Field3 AS PM, ClientSummary.[Client Nickname 2] AS [Project #], ClientSummary.[Client Nickname 1] AS Customer, ClientSummary.[In Reference To] AS [Job Name], ClientSummary.Field10 AS Contract, (select sum([Billable Slip Value]) from Util_bydate as U1 where U1.[Client Nickname 2] = ClientSummary.[Client Nickname 2]) AS [This Week], (select sum([Billable Slip Value]) from Util as U2 where U2.[Client Nickname 2] = ClientSummary.[Client Nickname 2] ) AS [To Date], [To Date]/[Contract] AS [% Spent], 0 AS Backlog, ClientSummary.[Total Slip Fees & Costs] AS Billed, ClientSummary.Payments AS Paid, ClientSummary.[Total A/R] AS Receivable, [Forms]![ReportMenu]![StartDate] AS [Start Date], [Forms]![ReportMenu]![EndDate] AS [End Date] FROM ClientSummary; Query 2: SELECT JobManagement_Summary.pm, JobManagement_Summary.[project #], JobManagement_Summary.Customer, JobManagement_Summary.[Job Name], JobManagement_Summary.Contract, IIf(IsNull([This Week]),0,[This Week]) AS [N_This Week], IIf(IsNull([To Date]),0,[To Date]) AS [N_To Date], [% Spent], JobManagement_Summary.Backlog, JobManagement_Summary.Billed, JobManagement_Summary.Paid, JobManagement_Summary.Receivable, JobManagement_Summary.[Start Date], JobManagement_Summary.[End Date] FROM JobManagement_Summary; When I run the report from query 2 these 3 fields don't appear. N_This Week, N_To Date and % Spent. All have no data. It isn't the IIF functions, as it doesn't matter if I have those in there or remove them. Any thoughts? If I connect directly to the first recordset it works fine, but then SQL throws the error message: Multi-level GROUP BY cause not allowed in subquery. Is there any way to get around that message to link to it directly or does anyone have ANY clue why these fields are coming back blank? I am at wits end here!

  • C++ Win32 API equivalent of CultureInfo.TwoLetterISOLanguageName

    - by Brian Gillespie
    The .NET framework makes it easy to get information about various locales; the Win32 C++ APIs are a bit harder to figure out. Is there an equivalent function in Win32 to get the two-letter ISO language name given an integer locale ID? In C# I'd do: System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo(1034); string iso = ci.TwoLetterISOLanguageName; // iso == "es" now.

  • ColdFusion CFC implementation of C# Partial Class?

    - by Brian David Berman
    Does ColdFusion offer a mechanism for splitting CFCs into multiple files? I am NOT talking about extension, I am talking about splitting the SAME CFC into multiple files; the same way C# allows for "partial" classes. The reason for this is because I am using T4 to generate a bunch of CFCs and I want to be able to tag functionality onto the generated CFC by doing so in another file. I want to do this in a way that doesn't violate the Open-Closed Principle.

  • parallel computation for an Iterator of elements in Java

    - by Brian Harris
    I've had the same need a few times now and wanted to get other thoughts on the right way to structure a solution. The need is to perform some operation on many elements on many threads without needing to have all elements in memory at once, just the ones under computation. As in, Iterables.partition is insufficient because it brings all elements into memory up front. Expressing it in code, I want to write a BulkCalc2 that does the same thing as BulkCalc1, just in parallel. Below is sample code that illustrates my best attempt. I'm not satisfied because it's big and ugly, but it does seem to accomplish my goals of keeping threads highly utilized until the work is done, propagating any exceptions during computation, and not having more than numThreads instances of BigThing necessarily in memory at once. I'll accept the answer which meets the stated goals in the most concise way, whether it's a way to improve my BulkCalc2 or a completely different solution. interface BigThing { int getId(); String getString(); } class Calc { // somewhat expensive computation double calc(BigThing bigThing) { Random r = new Random(bigThing.getString().hashCode()); double d = 0; for (int i = 0; i < 100000; i++) { d += r.nextDouble(); } return d; } } class BulkCalc1 { final Calc calc; public BulkCalc1(Calc calc) { this.calc = calc; } public TreeMap<Integer, Double> calc(Iterator<BigThing> in) { TreeMap<Integer, Double> results = Maps.newTreeMap(); while (in.hasNext()) { BigThing o = in.next(); results.put(o.getId(), calc.calc(o)); } return results; } } class SafeIterator<T> { final Iterator<T> in; SafeIterator(Iterator<T> in) { this.in = in; } synchronized T nextOrNull() { if (in.hasNext()) { return in.next(); } return null; } } class BulkCalc2 { final Calc calc; final int numThreads; public BulkCalc2(Calc calc, int numThreads) { this.calc = calc; this.numThreads = numThreads; } public TreeMap<Integer, Double> calc(Iterator<BigThing> in) { ExecutorService e = Executors.newFixedThreadPool(numThreads); List<Future<?>> futures = Lists.newLinkedList(); final Map<Integer, Double> results = new MapMaker().concurrencyLevel(numThreads).makeMap(); final SafeIterator<BigThing> it = new SafeIterator<BigThing>(in); for (int i = 0; i < numThreads; i++) { futures.add(e.submit(new Runnable() { @Override public void run() { while (true) { BigThing o = it.nextOrNull(); if (o == null) { return; } results.put(o.getId(), calc.calc(o)); } } })); } e.shutdown(); for (Future<?> future : futures) { try { future.get(); } catch (InterruptedException ex) { // swallowing is OK } catch (ExecutionException ex) { throw Throwables.propagate(ex.getCause()); } } return new TreeMap<Integer, Double>(results); } }

  • Net::SMTPFatalError in rails 2.3.4

  • Ruby ROXML - how to get an array to render its xml?

    - by Brian D.
    I'm trying to create a Messages object that inherits Array. The messages will gather a group of Message objects. I'm trying to create an xml output with ROXML that looks like this: <messages> <message> <type></type> <code></code> <body></body> </message> ... </messages> However, I can't figure out how to get the message objects in the Messages object to display in the xml. Here is the code I've been working with: require 'roxml' class Message include ROXML xml_accessor :type xml_accessor :code xml_accessor :body end class Messages < Array include ROXML # I think this is the problem - but how do I tell ROXML that # the messages are in this instance of array? xml_accessor :messages, :as => [Message] def add(message) self << message end end message = Message.new message.type = "error" message.code = "1234" message.body = "This is a test message." messages = Messages.new messages.add message puts messages.length puts messages.to_xml This outputs: 1 <messages/> So, the message object I added to messages isn't getting displayed. Anyone have any ideas? Or am I going about this the wrong way? Thanks for any help.

  • 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.

  • How do I get rid of these warnings?

    - by Brian Postow
    This is really several questions, but anyway... I'm working with a big project in XCode, relatively recently ported from MetroWorks (Yes, really) and there's a bunch of warnings that I want to get rid of. Every so often an IMPORTANT warning comes up, but I never look at them because there's too many garbage ones. So, if I can either figure out how to get XCode to stop giving the warning, or actually fix the problem, that would be great. Here are the warnings: It claims that <map.h> is antiquated. However, when I replace it with <map> my files don't compile. Evidently, there's something in map.h that isn't in map... this decimal constant is unsigned only in ISO C90 This is a large number being compared to an unsigned long. I have even cast it, with no effect. enumeral mismatch in conditional expression: <anonymous enum> vs <anonymous enum> This appears to be from a ?: operator. Possibly that the then and else branches don't evaluate to the same type? Except that in at least one case, it's (matchVp == NULL ? noErr : dupFNErr) And since those are both of type OSErr, which is mac defined... I'm not sure what's up. It also seems to come up when I have other pairs of mac constants... multi-character character constant This one is obvious. The problem is that I actually NEED multi-character constants... -fwritable-strings not compatible with literal CF/NSString I unchecked the "Strings are Read-Only" box in both the project and target settings... and it seems to have had no effect...

  • How can one make a web-site accessible only when someone has a dongle?

    - by Brian M. Hunt
    Suppose you want to add an extra layer of credentials on top of a SSL-encrypted login/password, but you don't want to increase complexity to the user. Is there a way to add the requirement of the possession of a dongle to web-server authentication schemes with existing cross-platform browser capabilities? In other words, to get access to the web-site, you would need a username, password, and a USB dongle that has been plugged into the client computer. The dongle would presumably do some sort of challenge/response. It'd be ideal if this dongle solution worked with Firefox automatically or with the simple addition of a plugin. Thoughts and suggestions are appreciated.

  • Can I interrupt javascript code and then continue on a keystroke?

    - by Brian Ramsay
    I am porting an old game from C to Javascript. I have run into an issue with display code where I would like to have the main game code call display methods without having to worry about how those status messages are displayed. In the original code, if the message is too long, the program just waits for the player to toggle through the messages with the spacebar and then continues. This doesn't work in javascript, because while I wait for an event, all of the other program code continues. I had thought to use a callback so that further code can execute when the player hits the designated key, but I can't see how that will be viable with a lot of calls to display.update(msg) scattered throughout the code. Can I architect things differently so the event-based, asynchronous model works, or is there some other solution that would allow me to implement a more traditional event loop? Am I making sense? Example: // this is what the original code does, but obviously doesn't work in Javascript display = { update : function(msg) { // if msg is too long // wait for user input // ok, we've got input, continue } }; // this is more javascript-y... display = { update : function(msg, when_finished) { // show part of the message $(document).addEvent('keydown', function(e) { // display the rest of the message when_finished(); }); } }; // but makes for amazingly nasty game code do_something(param, function() { // in case do_something calls display I have to // provide a callback for everything afterwards // this happens next, but what if do_the_next_thing needs to call display? // I have to wait again do_the_next_thing(param, function() { // now I have to do this again, ad infinitum } }

  • Why is lua crashing after extracting zip files?

  • Prefered method for looping sound flash as3

    - by Brian Heylin
    Hi there, I'm having some issues with looping a sound in flash AS3, in that when I tell the sound to loop I get a slight delay at the end/beginning of the audio. The audio is clipped correctly and will play without a gap on garage band. I know that there are issues with sound in general in flash, bugs with encodings and the inaccuracies with the SOUND_COMPLETE event (And Adobe should be embarrassed with their handling of these issues) I have tried to use the built in loop argument in the play method on the Sound class and also react on the SOUND_COMPLETE event, but both cause a delay. But has anyone come up with a technique for looping a sound without any noticeable gap?

  • Save batch file path to local harddisk

    - by Brian
    Hi, I have a batch file that is Run when a selfextraction file is executed. The self extracted files must be copied to to specefic place on the harddisc. In the batch file the user is asked where the path is (if it's not located the default place) Part of the batch file: @ECHO OFF IF EXIST "C:\Program Files\program\program.exe". ( set PROGRAMPATH=C:\Program Files\ ) ELSE ( echo Program folder was not found. Please enter the path for Program set /p PROGRAMPATH=Path: ) echo Copying data to "%PROGRAMPATH%"... copy /Y "*.txt" "%PROGRAMPATH%" Now for my question. If a user then enters a new path, is it possible to save that path. So when he executes the self extraction packagde again, it could remember that new path?
