  • How do I correctly SSH port forward using LiveReload on Redhat?

    - by program247365
    Referencing this page: http://feedback.livereload.com/knowledgebase/articles/86280-if-you-edit-files-directly-on-your-server It says you can remotely port forward the LiveReload specific port of 35729, using this command: ssh -L 35729:127.0.0.1:35729 mylogin@myremoteserverIP When I run the -v option, I get: debug1: Local connections to LOCALHOST:35729 forwarded to remote address 127.0.0.1:35729 debug1: Local forwarding listening on ::1 port 35729. debug1: channel 0: new [port listener] debug1: Local forwarding listening on 127.0.0.1 port 35729. debug1: channel 1: new [port listener] debug1: channel 2: new [client-session] debug1: Entering interactive session. debug1: Sending environment. debug1: client_input_channel_req: channel 2 rtype [email protected] reply 1 debug1: Connection to port 35729 forwarding to 127.0.0.1 port 35729 requested. debug1: channel 3: new [direct-tcpip] channel 3: open failed: connect failed: Connection refused debug1: channel 3: free: direct-tcpip: listening port 35729 for 127.0.0.1 port 35729, connect from 127.0.0.1 port 63673, nchannels 4 I thought editing my /etc/services with this line, would work, but it doesn't: livereload 35729/tcp # livereload usage with guard-livereload Every time I attempt to connect with the browser extension, I believe It's getting blocked by my server. What am I missing here? Do I need to edit /etc/services for this to work?

  • Redirecting or routing all traffic to OpenVPN on a Mac OS X client

    - by sdr56p
    I have configured an OpenVPN (2.2.1) server on an Ubuntu virtual machine in the Amazon elastic compute cloud. The server is up and running. I have installed OpenVPN (2.2.1) on a Mac OS X (10.8.2) client and I am using the openvpn2 binary to connect (in opposition to other clients like Tunnelblick or Viscosity). I can connect with the client and successfully ping or ssh the server through the tunnel. However, I can't redirect all internet traffic through the VPN even if I use the push "redirect-gateway def1 bypass-dhcp" option in the server.conf configurations. When I connect to the server with these configurations, I get a successful connection, but then an infinite series of error messages: "write UDPv4: No route to host (code=65)". Traffic routing seems to be compromised because I am not able to access anything anymore, not even the OpenVPN server (by pinging 10.8.0.1 for instance). This is beyond me. I am finding little help on the web and don't know what to try next. I don't think it is a problem of forwarding the traffic on the server since, first, I have also took care of that and, second, I can't even ping the VPN server locally through the tunnel (or ping anything at all for that matter). Thank you for your help. Here is the server.conf. file: port 1194 proto udp dev tun ca ca.crt cert ec2-server.crt key ec2-server.key # This file should be kept secret dh dh1024.pem server 10.8.0.0 255.255.255.0

  • Mapped network drive connection timeout

    - by Terix
    I have server "Alpha" and server "Beta". Server Beta has a shared folder, that is mapped on server Alpha as "X:" On server Alpha there is a .vbs script that runs and take some files on local drive and copy them on X: drive. My issue is if no user log on server Alpha for a long time, it seems like the tcp connection underneath the mapped drive has a timeout, and the vbs script fails on the copy of file. As soon I log with remote desktop on Alpha server, the .vbs is successfull on the copy of the files. I have made many tests, using file logs to check what was happening and I found no way to refresh the connection and let the .vbs be able to copy files unattended.. I have always to log with remote desktop on Alpha server to refresh the connection and let the .vbs copy the files without issues. What can I do to avoid to log every time? The .vbs script runs 3 times a day and is very annoying. I do not have control over server Beta so I cannot change anything there, and I am very limited on changes I can do on server Alpha ( I cannot change registry and that sort of things)

  • Implementing a 1 to many relationship with SQLite

    - by Patrick
    I have the following schema implemented successfully in my application. The application connects desk unit channels to IO unit channels. The DeskUnits and IOUnits tables are basically just a list of desk/IO units and the number of channels on each. For example a desk could be 4 or 12 channel. CREATE TABLE DeskUnits (Name TEXT, NumChannels NUMERIC); CREATE TABLE IOUnits (Name TEXT, NumChannels NUMERIC); CREATE TABLE RoutingTable (DeskUnitName TEXT, DeskUnitChannel NUMERIC, IOUnitName TEXT, IOUnitChannel NUMERIC); The RoutingTable 'table' then connects each DeskUnit channel to an IOUnit channel. For example the DeskUnit called "Desk1" channel 1 may route to IOunit name "IOUnit1" channel 2, etc. So far I hope this is pretty straightforward and understandable. The problem is, however, this is a strictly 1 to 1 relationship. Any DeskUnit channel can route to only 1 IOUnit channel. Now, I need to implement a 1 to many relationship. Where any DeskUnit channel can connect to multiple IOUnit channels. I realise I may have to rearrange the tables completely, but I am not sure the best way to go about this. I am fairly new to SQLite and databases in general so any help would be appreciated. Thanks Patrick

  • UITableView cell appearance update not working - iPhone

    - by Jack Nutkins
    I have this piece of code which I'm using to set the alpha and accessibility of one of my tables cells dependent on a value stored in user defaults: - (void) viewDidAppear:(BOOL)animated{ [self reloadTableData]; } - (void) reloadTableData { if ([[userDefaults objectForKey:@"canDeleteReceipts"] isEqualToString:@"0"]) { NSIndexPath *path = [NSIndexPath indexPathForRow:0 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 0.2; cell.userInteractionEnabled = NO; } else { NSIndexPath *path = [NSIndexPath indexPathForRow:0 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 1; cell.userInteractionEnabled = YES; } if ([[userDefaults objectForKey:@"canDeleteMileages"] isEqualToString:@"0"]) { NSIndexPath *path = [NSIndexPath indexPathForRow:1 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 0.2; cell.userInteractionEnabled = NO; } else { NSIndexPath *path = [NSIndexPath indexPathForRow:1 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 1; cell.userInteractionEnabled = YES; } if ([[userDefaults objectForKey:@"canDeleteAll"] isEqualToString:@"0"]) { NSIndexPath *path = [NSIndexPath indexPathForRow:2 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 0.2; cell.userInteractionEnabled = NO; NSLog(@"In Here"); } else { NSIndexPath *path = [NSIndexPath indexPathForRow:2 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 1; cell.userInteractionEnabled = YES; } } The value stored in userDefaults is '0' so the cell in section 8 row 2 should be greyed out and disabled, however this doesn't happen and the cell is still selectable with an alpha of 1... The log statement 'In Here' is called so it seems to be executing the right code, but that code doesn't seem to be doing anything. Can anyone explain what I've done wrong? Thanks, Jack

  • Navigating Libgdx Menu with arrow keys or controller

    - by Phil Royer
    I'm attempting to make my menu navigable with the arrow keys or via the d-pad on a controller. So Far I've had no luck. The question is: Can someone walk me through how to make my current menu or any libgdx menu keyboard accessible? I'm a bit noobish with some stuff and I come from a Javascript background. Here's an example of what I'm trying to do: http://dl.dropboxusercontent.com/u/39448/webgl/qb/qb.html For a simple menu that you can just add a few buttons to and it run out of the box use this: http://www.sadafnoor.com/blog/how-to-create-simple-menu-in-libgdx/ Or you can use my code but I use a lot of custom styles.

  • Why does my Intel HDA onboard sound card not have a "Mix" device / channel?

    - by Hanno Fietz
    I want to be able to record what my sound card outputs on the speakers / headphones. This question is all over the interwebs again and again, and there seem to be two outcomes: in your selection of audio input devices, there's a device called "Stereo Mix", or similar, which is the "loopback" device for audio. Choose that in your recording tool and you're done. there's no such device and only speculative posts about why that may be. Now, I'm using ALSA and an Intel HDA chipset on my mainboard under Kubuntu Karmic. I have some 5-10 output channels and "Mic", "Front Mic" and "Line" for input. All of those are available in KMix, Audacity and other software. No "loopback" / "Mix" / whatever. Do I have to get some driver / kernel module set up ALSA in some way set up my system configuration in some way use a software solution (such as JACK) I had a look at JACK, and found it rather hard to understand, it's either an expert tool or just clumsy, I couldn't say. At least, I wasn't able to figure out how to achieve what I wanted. One of my problems seems to be that I don't understand where and how the mixing happens. Are there sound cards which just aren't able to do it? Why does the sound card matter at all, since I could in theory grab the data stream at some point before it goes to the hardware, right?

  • How to stop windows resizing when the monitor display channel is turned off / switched to different source

    - by Heartspeace
    Have a new 6870 ati radeon adapter with its drivers set to 1080p 60hz resolution hooked up to a 2008 47" high end Samsung HDMI based TV. However, when the tv is turned to a different hdmi input -(when I come back into windows) somehow Windows decides to resize all the open apps to a lower resolution - including some of the side docked hidden pop-outs. When it resizes those though - it just sticked the pop-outs in the middle of the screen and all the resized windows from the open applications in the top left corner - all of them stacked on top of each other and resized to the smaller resolution. The things that seem to be ok after returning are the icons on the desktop, the taskbar, and the sidebar. Anyone have any knowledge of 1) how this happens 2) why it happens 3) how to stop it from resizing the applications and some of the docked pop-outs (they are not really resized after returning - they are just stuck in the middle of the screen approximately where they would be if the right or bottom sidebar should be if the screen was resized to that lower resolution). My hypothesis is that upon losing HDMI signal - that Windows is told by something (driver, or windows itself) that the resolution to be without a signal being present (noting that HDMI signals and handshakes are two way on HDMI devices. If it loses the signal or the tv is switched to another device - then the display adapter must figure that out and tell Windows or figures it out and designs randomly to change the display size). Any and all help is most appreciated. I asked AMD/ATI - but they said they don't know why or how this is happening. I was hoping that maybe this is THE place that the super users truly go to - those that develop display adapter drivers, or that dive deeply into these areas of windows. If there is better sites or just competing sites - please advise - noting I have already written AMD/ATI. HP Response / Additions 4/7/2011 It is really nice to get your reply Shinrai. (BTW is it proper etiquette on these forums to have a discussion?) Yet 'only one issue' - I am using a single display in this case - so Windows doesn't move application windows to another desktop. Windows (or something) decides to shrink the desktop it currently has and resize all windows to the maximum size of the desktop. As such I would be glad if Windows would just keep the current size of the one desktop that is in operation. I also know that this does NOT happen on monitors connected with DVI. There I have had one and two monitors setup and it doesn't resize those screens at all when disconnecting monitors, turning them off, whatever... they stay solid - everything in place - to such an extent that if you forgot the other monitor is off - you will have troubles finding some windows without using one of the control app utilities. So if I could even get the HDMI handling by Windows (or the display driver) ( 1] which is doing this anyway the display driver or Windows - and 2] where is that other resolution size (1024x768) coming from - its not the smallest and its not the largest?) to be having like DVI - Life would be golden (for this aspect anyway). ** found others with same problem in this thread: http://hardforum.com/showthread.php?t=1507324 Thanks, HP

  • trie reg exp parse step over char and continue

    - by forest.peterson
    Setup: 1) a string trie database formed from linked nodes and a vector array linking to the next node terminating in a leaf, 2) a recursive regular expression function that if A) char '*' continues down all paths until string length limit is reached, then continues down remaining string paths if valid, and B) char '?' continues down all paths for 1 char and then continues down remaining string paths if valid. 3) after reg expression the candidate strings are measured for edit distance against the 'try' string. Problem: the reg expression works fine for adding chars or swapping ? for a char but if the remaining string has an error then there is not a valid path to a terminating leaf; making the matching function redundant. I tried adding a 'step-over' ? char if the end of the node vector was reached and then followed every path of that node - allowing this step-over only once; resulted in a memory exception; I cannot find logically why it is accessing the vector out of range - bactracking? Questions: 1) how can the regular expression step over an invalid char and continue with the path? 2) why is swapping the 'sticking' char for '?' resulting in an overflow? Function: void Ontology::matchRegExpHelper(nodeT *w, string inWild, Set<string> &matchSet, string out, int level, int pos, int stepover) { if (inWild=="") { matchSet.add(out); } else { if (w->alpha.size() == pos) { int testLength = out.length() + inWild.length(); if (stepover == 0 && matchSet.size() == 0 && out.length() > 8 && testLength == tokenLength) {//candidate generator inWild[0] = '?'; matchRegExpHelper(w, inWild, matchSet, out, level, 0, stepover+1); } else return; //giveup on this path } if (inWild[0] == '?' || (inWild[0] == '*' && (out.length() + inWild.length() ) == level ) ) { //wild matchRegExpHelper(w->alpha[pos].next, inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover);//follow path -> if ontology is full, treat '*' like a '?' } else if (inWild[0] == '*') matchRegExpHelper(w->alpha[pos].next, '*'+inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover); //keep adding chars if (inWild[0] == w->alpha[pos].letter) //follow self matchRegExpHelper(w->alpha[pos].next, inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover); //follow char matchRegExpHelper(w, inWild, matchSet, out, level, pos+1, stepover);//check next path } } Error Message: +str "Attempt to access index 1 in a vector of size 1." std::basic_string<char,std::char_traits<char>,std::allocator<char> > +err {msg="Attempt to access index 1 in a vector of size 1." } ErrorException Note: this function works fine for hundreds of test strings with '*' wilds if the extra stepover gate is not used Semi-Solved: I place a pos < w->alpha.size() condition on each path that calls w->alpha[pos]... - this prevented the backtrack calls from attempting to access the vector with an out of bounds index value. Still have other issues to work out - it loops infinitely adding the ? and backtracking to remove it, then repeat. But, moving forward now. Revised question: why during backtracking is the position index accumulating and/or not deincrementing - so at somepoint it calls w->alpha[pos]... with an invalid position that is either remaining from the next node or somehow incremented pos+1 when passing upward?

  • Setting reply priority on Wifi network with QoS?

    - by Omega
    When using a Station and Access Point that support QoS over Wifi, is it possible to set the priority (= Traffic Identifier = TID = QoS channel) of the reply? For example when sending a ICMP ping request using a high priority (= QoS channel), is it possible to force the station to use that same priority (= QoS channel) when sending the reply? A related question: Is it possible to force the station into using a different QoS channel?

    Trying to create a direct link to an IRC channel with double octothorpes (##). Freenode policy dictates off-topic channels require ## before the channel name. This O'Reilly 'hack' post gives solid instructions for how to link to a channel and open in the default client on a system, but no guidance for channels with doubles. Links to single channels are formatted as "irc://irc-server:port/channel?key"

  • How to proceed on the waypoint path?

    - by Alpha Carinae
    I'm using Dijkstra algorithm to find shortest path and I'm drawing this path on the screen. As the character object moves on, path updates itself(shortens as the object approaches the target and gets longer as the object moves away from it.) I tried to visualize my problem. This is the beginning state. 'A' node is the target, path is the blue and the object is the green one. I draw this path, from object to the closest node. In this case my problem occurs. Because 'D' node is more closer to the object than 'C' node, something like this happens: So, how can i decide that the object passed the 'D' node? Path should be look like this: One thing comes to my mind is that I use some distance variables between the two closest nodes in the route path. (In this example these are 'C' and 'D' nodes.) As the object approaches 'C' and moves away from the 'D' node at the same time, this means character passed the 'D'. However, I think there are some standardized and easy ways to solve this. What approach should I take?

  • Why 32-bit color EGL configurations fail with EGL_BAD_MATCH on Moto Droid?

    - by Gilead
    I'm trying to figure out why certain EGL configurations cause eglMakeCurrent() call to return EGL_BAD_MATCH on Motorola Droid running Android 2.1u1. This is a full list of hardware-accelerated EGL configurations (those with EGL_CONFIG_CAVEAT == EGL_NONE) as there's a few others with EGL_CONFIG_CAVEAT == EGL_SLOW_CONFIG but those are backed by PixelFlinger 1.2 meaning they're using software renderer.

Why? 2. WHY?! :) 3. How do I tell which ones would fail before actually trying to use them? The code below is as simple as it can get. I put if (v[0] == 6) there to check different configs, normally they're chosen by half-clever config matcher :) private void createSurface(SurfaceHolder holder) { egl = (EGL10)EGLContext.getEGL(); eglDisplay = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY); egl.eglInitialize(eglDisplay, null); int[] numConfigs = new int[1]; egl.eglChooseConfig(eglDisplay, new int[] { EGL10.EGL_NONE }, null, 0, numConfigs); EGLConfig[] configs = new EGLConfig[numConfigs[0]]; egl.eglChooseConfig(eglDisplay, new int[] { EGL10.EGL_NONE }, configs, numConfigs[0], numConfigs); int[] v = new int[1]; for (EGLConfig c : configs) { egl.eglGetConfigAttrib(eglDisplay, c, EGL10.EGL_CONFIG_ID, v); if (v[0] == 6) { eglConfig = c; } } eglContext = egl.eglCreateContext(eglDisplay, eglConfig, EGL10.EGL_NO_CONTEXT, null); if (eglContext == null || eglContext == EGL10.EGL_NO_CONTEXT) { throw new RuntimeException("Unable to create EGL context"); } eglSurface = egl.eglCreateWindowSurface(eglDisplay, eglConfig, holder, null); if (eglSurface == null || eglSurface == EGL10.EGL_NO_SURFACE) { throw new RuntimeException("Unable to create EGL surface"); } if (!egl.eglMakeCurrent(eglDisplay, eglSurface, eglSurface, eglContext)) { throw new RuntimeException("Unable to make EGL current"); } gl = (GL10)eglContext.getGL(); }

  • iPhone metering problems

    - by Eric Christensen
    When I'm recording an AVAudioRecorder object, I repeat a chunk of code via an NSTimer that includes: [soundrecording updateMeters]; NSLog(@"channel 0 average:%f, peak:%f",[soundrecording averagePowerForChannel:0],[soundrecording peakPowerForChannel:0]); NSLog(@"channel 1 average:%f, peak:%f",[soundrecording averagePowerForChannel:1],[soundrecording peakPowerForChannel:1]); When I'm recording a mono file, the peak power for channel 0 is just what you'd expect, a float from -160 to 0. But average power for channel 0 is always zero. (And, of course, the values for channel 1 are both zero.) When I'm recording a stereo file, both the average and peak values for both channels are as expected. Any thoughts on why, when recording a mono file, the average value for channel 0 isn't returning correctly, even though the peak is? Thanks!

  • How Can I create different selectors for accepting new connection in java NIO

    I want to write java tcp socket programming using java NIO. Its working fine. But I am using the same selector for accepting reading from and writing to the clients. How Can I create different selectors for accepting new connection in java NIO, reading and writing. Is there any online help. Actually when I am busy in reading or writing my selector uses more iterator. So If more number of clients are connected then performance of accepting new coneection became slow. But I donot want the accepting clients to be slow // Create a selector and register two socket channels Selector selector = null; try { // Create the selector selector = Selector.open(); // Create two non-blocking sockets. This method is implemented in // e173 Creating a Non-Blocking Socket. SocketChannel sChannel1 = createSocketChannel("hostname.com", 80); SocketChannel sChannel2 = createSocketChannel("hostname.com", 80); // Register the channel with selector, listening for all events sChannel1.register(selector, sChannel1.validOps()); sChannel2.register(selector, sChannel1.validOps()); } catch (IOException e) { } // Wait for events while (true) { try { // Wait for an event selector.select(); } catch (IOException e) { // Handle error with selector break; } // Get list of selection keys with pending events Iterator it = selector.selectedKeys().iterator(); // Process each key at a time while (it.hasNext()) { // Get the selection key SelectionKey selKey = (SelectionKey)it.next(); // Remove it from the list to indicate that it is being processed it.remove(); try { processSelectionKey(selKey); } catch (IOException e) { // Handle error with channel and unregister selKey.cancel(); } } } public void processSelectionKey(SelectionKey selKey) throws IOException { // Since the ready operations are cumulative, // need to check readiness for each operation if (selKey.isValid() && selKey.isConnectable()) { // Get channel with connection request SocketChannel sChannel = (SocketChannel)selKey.channel(); boolean success = sChannel.finishConnect(); if (!success) { // An error occurred; handle it // Unregister the channel with this selector selKey.cancel(); } } if (selKey.isValid() && selKey.isReadable()) { // Get channel with bytes to read SocketChannel sChannel = (SocketChannel)selKey.channel(); // See e174 Reading from a SocketChannel } if (selKey.isValid() && selKey.isWritable()) { // Get channel that's ready for more bytes SocketChannel sChannel = (SocketChannel)selKey.channel(); } } Thanks Deepak

However, when a user searches UNIX, the engine must choose: word or operating_system. Also, when a user searches windows (small letter 'w'), the engine chooses word, but should also show Assuming 'windows' is a word. Use as an <a href="etc..">operating system</a> instead.

  • iPhone+Quartz+OpenGL. What is the correct way for Quartz and OpenGL to play nice together regarding

    - by dugla
    So we know the CoreGraphics/Quartz imaging model is based on pre-multiplied alpha. We also know that OpenGL blending is based on un-premultiplied alpha. What is the best practice to avoid head explosion when doing blending with textures that are derived from pre-multiplied alpha imagery (PNG files generated in Photoshop with pre-multiplied alpha). Given the apples/oranges mish mash of Quartz and OpenGL, what is the correct glBlendFunc for doing the fundamental Porter/Duff "over" operation? Typical example: A simple paint program. Brush shapes are texture-map patterns created from pre-multiplied alpha rgba images. Paint color is specified via glColor4(...) with the alpha channel used to control paint transparency. GL_MODULATE is used so the brush texture multiplies the (translucent) paint color to blend the color into the canvas. Problem: The texture is premult. The color is not. What is the correct way to handle this fundamental inconsistency? Thanks, Doug

  • Is is possible to make a shaped, alpha-blended dialog?

    - by jgaa
    I'm making a non-rectangular dialog, modelled over an image from Photoshop (the image is the background of the dialog, and the user will see trough the transparent part of the image). I'ts like a dashboard-style window for a media-app with a few custom-drawn controls. Most of the background-image is either opaque or 100% transparent - but in between there is a thin area of partially transparent pixels, ment to blend the image smootly into the background. This works great for web-graphics, but I have not found a way to make this work for Windows windows. I'm using the Windows Template Library (WTL), msvc 2008 - and the app must run on Windows XP as well as Vista and Windows 7. Currently, I'm simply using the opaque part of the background-image to create a GDI clipping-region, but this gives pretty rough edges. Does anyone know about any API functions to accomplish this (part of WTL, or reachable from WTL)?

  • TFS 2010 Source Branches Never The Same

    - by Lukasz
    I have my root branch lets call it Alpha and one branch that was branched from that root lets call it Beta. I made some changes in the Beta branch and merged them back to Alpha. In theory now Alpha and Beta should be identical branches and when I do a diff they are identical. If I attempt to merge Alpha with Beta again without making any changes the changes I originally merged from Beta to Alpha will merge again from Alpha to Beta. Completing that merge and checking in the branches are the same. Now I can merge again. I can do this over and over again with no end. I was just wondering if anyone has ran into this problem before and how it can be fix. At first I thought it was harmless but when I make more changes in the Beta branch and merge the new changes as well as the original changes get merges overriding changes to these files making a mess. Thanks!

    You may ask why do I need it? I have to detect all white objects at the B/W image. I'm coloring each object and taking its rect. In order fill each object with different color I would be very happy to use a function that can for a given color gimme a next one or so. In Qt there is a nice one that is called nextColor or so, returns the integer representing the next color(which can be easily translated to RGB). Does Cocoa have sth like that?
