Jesse, Speaking from experience, Pik is a viable solution if you want to run both versions of Ruby on the same Windows box (at least until RVM 2 is released with Windows support). It should only require adding the Ruby from the RailsInstaller installation to Pik so that it is aware. Then, you should be able to use Pik and install other versions of Ruby. The other option that is a bit more complicated is using Cygwin. This will actually allow you to install RVM and run it in a sandboxed Unix environment on Windows. It's something that I've been meaning to write up how to do but just haven't gotten around to it. Cheers, Evan

Things to check in order: Locks on the server side. Network interruption and timeout. Responsiveness on the server. Long-running queries.

Well, I seem to have finally gotten to the root of the problem. It seems that when you execute a cURL call to the same server as the script that is doing the calling, and if both the "caller" and the "callee" scripts are trying to use the same session id, a deadlock occurs, causing both scripts to wait till the other releases the session. I ended up adding a test to see if there's already a session id in use, and if so, the calling script doesn't start a session. If there is no session id, then the caller starts a session, obtains the session id, then destroys the session, which allows the "callee" script unfettered access to said session, thus removing the deadlock situation. Below is the code I used to do this: $convo_id = (isset ($request_vars['convo_id'])) ? $request_vars['convo_id']

Without going and writing code to check, here are some likely culprits. 1) Your 5 second timeout is not long enough to download the full file "boo.mp3", so the timeout stops the operation. 2) Your web server is taking too long to respond (unlikely, but possible over a mobile network) It might be best to either remove the timeout value altogether, or set it to a more realistic value.

Well, I never figured out why the build was failing for me. However, as of video.js version 4.4.2, I am able to build the project without problems. Maybe it was a configuration problem on my end, or maybe some bugs got fixed on their end, but this issue is now resolved.

register_Timer.SynchronizingObject = this; This completely defeats the reason for using System.Timers.Timer. It prevents the Elapsed event handler from being raised on a threadpool thread, the property ensures it will run on the UI thread. Which is what you wanted. But you still get all the disadvantages of that Timer class. Particularly its habit for swallowing exceptions without a diagnostic is very ugly. As well as continuing to raise the Elapsed event after the form is closed, ensuring this cannot happen is a very difficult problem to solve, there are two inherent race conditions. .NET 1.0 had some design mistakes related to threading, this was one of them. Just don't do this, use a System.Windows.Forms.Timer instead. It will work exactly like your timer, minus all the d

The SCM (the component which handles services) has built-in auto-restart logic that you can take advantage of to restart your service, as necessary. Additionally and/or alternatively, you can configure 'custom actions' to be associated with a failure of the service - the custom action can include launching a program of your own, which could then log the failure, and perhaps manually restart your service. You can read more about such custom actions on MSDN by looking at the documentation of the structure used to configure such actions: SERVICE_FAILURE_ACTIONS. Once you fill that structure, you notify the SCM by calling the ChangeServiceConfig2 function. Please don't ask "well, what happens if my failure handler program crashes" :)

I am told that the data will remain intact if you make no changes to the schema of the db. Here is the link from a Microsoft forum: http://social.msdn.microsoft.com/Forums/en-US/f4550181-468a-4902-9ee0-d8554a127f92/upgrade-windows-store-app-do-i-lose-sqlite-data

Take a look at the MSDN topic REINSTALLMODE property. The "v" is needed by the minor upgrade, the "o" tells it to only overwrite older files and the "a" tells it to reinstall all files regardless of hash or version. So REINSTALLMODE=vamus should be what you need. However, if the files in the installer were properly versioned this shouldn't be a problem in the first place.

Windows Server 2012 includes latest version of SMB protocol 3.0 and it full of really interesting updates and improvements (details and some relevant discussion here). As with any serious improvements there is a compromise in terms of legacy clients support. Probably there is no support for SMB 3.0 on your Samba client side or some backward compatibility should be enabled on Server 2012 side.

This error can occur in every Language-Version and depending on the Word-Version you use, it may not be easy to prevent hidden dialogs. Which Word-Version do you use? But first, your parameters are off by one (i think). ReadOnly is the third parameter and thats why _isVisible my not be working. I tried to set objWord.Application.Visible to true and it worked for me. Maybe something else is wrong too? One quick solution may be setting OpenAndRepair to true. Its the 13. Parameter, right behind isVisible. Otherwise have a look at this Link: How To Dismiss a Dialog Box Displayed by an Office Application with Visual Basic.

Note that you do not need MinGW to run pandas, it's a optional. But if you like to use it than check this page: http://wiki.cython.org/InstallingOnWindows

Quoting one of my previous answers: HTTP Upgrade is used to indicate a preference or requirement to switch to a different version of HTTP or to another protocol, if possible: The Upgrade general-header allows the client to specify what additional communication protocols it supports and would like to use if the server finds it appropriate to switch protocols. The server MUST use the Upgrade header field within a 101 (Switching Protocols) response to indicate which protocol(s) are being switched. Upgrade = "Upgrade" ":" 1#product For example, Upgrade: HTTP/2.0, SHTTP/1.3, IRC/6.9, RTA/x11 The Upgrade header field is intended to provide a simple mechanism for transition from HTTP/1.1 to some other, incompatible protocol. According to the IANA regist

The typical design pattern for database updates in an app goes something like the code below and every time you update your application where a database change is required, you bump the database version used in your SQLiteOpenHelper-derived class. This, of course, presumes you used SQLiteOpenHelper to manage getting a reference to your SQLite DB in your provider: public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { if (oldVersion == 1) { // DO WORK TO UPGRADE FROM VERSION 1 to 2 oldVersion += 1; } if (oldVersion == 2) { // DO WORK TO UPGRADE FROM VERSION 2 to 3 oldVersion += 1; } if (oldVersion == 3) { // DO WORK TO UPGRADE FROM VERSION 3 to 4 oldV

This has seen when a related entity in another context (and on another thread) has been modified but not yet persisted. The scenario: A --> B Due to a bug B had pending changes, in another context, on another thread. The Bug caused B to hang around instead of saving or rolling it back. Attempting to save A in the current context/thread will will cause the wait for the other thread to release the lock on B. Only successful way to trouble shoot was to list all pending entities and compare to ones in the blocked thread. Took a while :( I am still looking for something that list all locks on the database and entities.

The current version of MPJ-Express uses Java Service Wrapper binaries to launch daemons on remote nodes. The current version (v0.38 I assume) does not have hard/soft float ABIs for ARM. Please wait for the next public release, I hope they will incorporate ARM support for that.

It's a bit late but the log command is probably trying to page results and is waiting for stdin, try the following to turn off the pager: git = sh.git.bake("--no-pager", _cwd=cwd) git.log('-n 1', '--pretty=%H')

Project + Properties, Debug tab, tick the "Enable native code debugging" option. Ensure that you've got the Microsoft Symbol server enabled (Tools + Options, Debugging, Symbols), I know you do :) You can now use Debug + Break All and see what's going on inside the browser. Do so repeatedly to get the lay of the land. You'll see that Javascript is executing (jscript8.dll) and constantly forcing the layout engine to recalculate layout, never getting the job done. Browsers in general are vulnerable to Javascript that's stuck in an endless loop. A regular browser tends to put up a dialog after several dozen seconds to allow the user to abort the JS, but WebBrowser doesn't have that feature. Nor does it have the dev tools so debugging the JS isn't going to be a great joy either. This is

From the script I can see this comment: # need to use "java.ext.dirs" because "-jar" causes classpath to be ignored # might need more memory, e.g. -Xmx128M but anyway both command work for me: java -Djava.ext.dirs=. -jar draw9patch.jar java -jar draw9patch.jar Probably you have a failing jar. Can you try with mine? [I'm on a Mac running Mountain Lion 10.8.4 but I had no problem with Lion 10.7.5]

You can do this, otherwise your gui thread will have to wait until the endless while loop finishes; consider adding a break function if the following thread isn't what you want. using System.Threading; Thread th = new Thread(new ThreadStart(delegate { //while loop })); th.Start();

GUI elements from a Windows Service are shown on Session 0. On Windows XP & 2003, users were allowed to log in to Session 0 and interact normally with the windows created by a service, but Microsoft put a knife in the heart of interactive services in Vista (and beyond) by isolating Session 0. So, to answer your specific questions: Is a process running in the context of a Service (the Service itself or any process it starts) "allowed" to make Windows API calls that display a visible GUI? Will most Windows API calls (e.g. creating and showing a window, using Shell_NotifyIcon, etc.) behave the same in the invisible session of the service? Yes, GUI calls are allowed and should succeed as normal. The only notable exceptions that I know of are those related to tray icons b

First: Note that go test will create, compile and run a test program which intercept output from each test so you will not see output from your tests until the test finishes (in this moment the output is printed). Two issues with your code: If you cannot start the tcp server t is not notified, you only do Printf here and continue as if everything was fine. You call t.FailNow from a different goroutine than your test runs in. You must not do this. See http://golang.org/pkg/testing/#T.FailNow Fixing those might at least show what else goes wrong. Also: Take a look at how package net/http does it's testing.

Check this issue Quoting Isaac Schlueter: The good news is that you're no longer leaking memory. The bad news is that you do indeed need to add error listeners to your objects. In most apps, you can usually treat ECONNRESET as roughly the same as a graceful close. Just make sure that you actually stop using that socket, since it's now closed. However, it's not a graceful close, since it's not in any sense "graceful". Prior to v0.8.20, node would happily buffer all writes to reset sockets, causing memory explosion death.

If you just try calling update yourself, instead of passing it to FTP.storbinary, you'll see the problem immediately: >>> update('') UnboundLocalError: local variable 'count' referenced before assignment If you want to update a global variable, you have to mark it global explicitly: def update(block): global count count += 1 print count See the FAQ entry Why am I getting an UnboundLocalError when the variable has a value? and the following question What are the rules for local and global variables in Python?, and the docs on global, for more details. A better way to solve this would be to write a class: class FtpHandler(object): def __init__(self): self.count = 0 def update(self, block): self.count += 1 print self.count Then, to

Looks like you may have a cartesian join here. http://www.orafaq.com/wiki/Cartesian_join I'm not sure exactly how your database keys are constructed so I just guessed below, but it may give you an idea of how you need to link your tables. These are ANSI joins, not Oracle-specific. I recommend you learn to use these types of joins so your code is more portable. I hope this helps. For outer joins use FULL JOIN for inner joins use JOIN or INNER JOIN. For left/right joins use LEFT JOIN or RIGHT JOIN. FROM tickets t JOIN customer_care_tickets cct ON t.ticket_id = cct.ticket_id JOIN accounts a ON cct.account_id = a.account_id JOIN orders o ON o.ticket_id = t.ticket_id WHERE t.owner IN (SELECT cont.contact_id FROM contacts cont WHERE ( c

Please read the javadocs... it will only have n > 0 if a some OP was selected. This will happen in your example if a socket is accepted. Just do a telnet localhost 1234 and you will see it in action.

I am editing your code, try this: WebClient client = new WebClient(); string url = lines[i]; try { string downloadString = client.DownloadString(url); client.Dispose(); //dispose the object because you don't need it anynmore findNewListings(downloadString, url); } catch (Exception exce) { MessageBox.Show("Error downlaoding page: " + exce.Message); } If an object is no longer in use, its better to Dispose it.

I've had exactly the same problem and could solve it using the answer here http://stackoverflow.com/a/5504530/1275767 which works by moving the projects out of the workspace and back in again after Eclipse has been started and stopped. Starting it with -clean -data started eclipse but whenever I switched the workspace using the eclipse gui it wouldn't load.

cat hangs if no input is given -- as well as many other programs. One of your paths are most probably empty, as you're able to go through the if statement: $ if [ -f ]; then echo "foo"; fi foo Once you inside the block, you hang on the call cat <empty>. As pointed by @ruakh, you should get it to work double-quoting the variable.

It's because you have never actually launched your task. You call [task launchPath]; That just returns the task's path as a string, it doesn't actually launch the task. You want [task launch];

Well it's a streaming API, so it will stream infinitely. Hence if you are trying to read to the end of stream, it will block forever until you run out of memory or get disconnected due to network error etc. You need to process the data while connected to the stream. If I were you I'd just use a client library (see https://dev.twitter.com/docs/twitter-libraries).

bash-3.2$ ?? That looks like the postgres prompt to me. You should be at a prompt like: ~/rails_projects/my_app$ Try typing: bash-3.2$ exit to get back to a prompt you can recognize.

While I cannot speak to this specifically, what seems to have happened is that I went home for the night and suspended my computer. When I came into work this morning and resumed my computer it seems to be working exactly as expected. I can only assume that the "suspend/resume" is equivalent to a reboot which has forced a correct reference to the base Gtk libraries. But this is only a guess. I miss linux :(

try to debug it. pause the program when it hangs and see where it hangs. if it hangs on the SQL query you might want to put a timeout on it. also you shouldn't create the query like this cmd.CommandText = "SELECT last_name +', '+ first_name +' ('+major_key+') ' from name where id ='" + textBox1.Text.Replace(@"L", "") + "'"; it's open to sql injections. use parameterized sql or other form of protection: SqlCommand command = new SqlCommand("SELECT last_name +', '+ first_name +' ('+major_key+') ' from name where id =@Name" command.Parameters.Add(new SqlParameter("Name", textBox1.Text.Replace(@"L", ""))); EDIT if you want to put a timeout on the connection you can look here at MSDN: you can set the timeout parameter in the connection string or simply DBConnection.ConnectionTimeo

Easy answer after much head scratching. Don't use Cygwin for github access. An alternative is to do all your normal terminal functions in Cygwin and then use Windows Command Line for git push origin Be sure to have ssh keys added to your account. Here are steps to add ssh to github. Also be sure your ssh keys have a passphrase.

Your regex is causing catastrophic backtracking. Briefly, your regex has terms that can both capture the same part of the input, but fails to do so. The regex engine must try all combinations before failing and due to the matching tree created, each extra character doubles the number of ways the match can be made. Creating and traversing this tree leads to a geometrically exponential execution time proportional to 2^n - which you are seeing. You may find that changing your dual expression to a possessive quantifier (ie ++ rather than +) stops this behaviour, because with ++ once characters are consumed, they stay consumed. Incidentally, this expression [-a-zA-z0-9_''^&+?:] may be rewritten as: [-w''^&+?:] Because: inside a character class (almost) all characters lose t

When you need lots of threads it is better to use thread pool. I found that there is python binding for that, so definitely you should try this. Here is similar topic. Sadly there is no python binding for QtConcurrent. It is nice API but it uses templates and it is badly documented.

I think I figured it out. The command I was running included an extra line break after the user name. As in, I was trying to execute this pg_restore --verbose --clean --no-acl --no-owner -h localhost -U myusername -d mydb latest.dump instead of this pg_restore --verbose --clean --no-acl --no-owner -h localhost -U myusername -d mydb latest.dump For some reason that extra linebreak was gumming things up. Once I removed it pg_restore worked properly.

So you have |r1| = 50,000 and |r2| = 1,000,000. If you want to compare each r1 against each r2, you have 50,000 * 1,000,000 = 50,000,000,000. 50 BILLION comparisons you need to make. If each comparison takes 1 ms, it's still going to take you 50,000,000 (fifty million) seconds to perform this comparison. This is 578 days. The only possible way I can see you reducing this complexity would be if you were to create a r1 and r2 map on node p keyed on SOMEPROPERTY. Then you would just need to get the list of r1 for SOMEPROPERTY and the list of r2 by SOMEPROPERTY.

I think the way the program is written, it's expecting data to be passed in from stdin: ms.load(sys.stdin) so you need: something | quarqd_messages.py --header > message-headers.h
