• Computer speakers receive radio station signal

  - by squircle

  I have a set of Logitech 5.1 speakers where each speaker and the source plug into the subwoofer. I'm using a Griffin Firewave with output from my MacBook Pro, and output from my custom-built desktop with a switch in the middle (built it myself out of an old Belkin A/B parallel switch). Recently, I've noticed that I can hear a local Punjabi radio station being picked up by my speakers, and the volume of this interference increases as I increase the volume of the speakers. I'm fairly sure that this radio station is at the low-end of the FM spectrum, below 90MHz (or it may be at the high end, above 105MHz, my memory isn't infallible). It gets quite annoying as I can't put my audio very loud without the interference. I've tried to put a ferrite core on the input cable just before the 3.5mm jacks plug into the subwoofer. I don't know if putting the same core around all three of the cables (green, black, orange) would negate the effects, but I'm assuming not. There has been no change. Is there any reason why this would be happening? I'm assuming the interference is coming somewhere between the FireWave and the subwoofer, because the noise gets amplified with volume increases. If anybody has any suggestions, I'd be grateful!

• Dock displays low-resolution icons

  - by squircle

  Recently, I've noticed that the dock has been starting to display low-resolution icons in place of the former high-resolution icons for common apps like Stickies, Word, iTunes and Preview. Looking at the .icns file within each program, all copies of the icon are present within the file (high and low resolutions), but the dock refuses to display them, leaving some programs looking like this: Restarting doesn't stop this behaviour, nor does a killall Dock, nor removing the icon and replacing it in the dock. In Finder, the icons display normally. Does anybody know what may be causing this issue? Thanks!

• Looking for a real DisplayPort hub/splitter

  - by squircle

  In my search for a new display, I came across the Dell Multi-Monitor Hub MMH11, which seemed to be an alternative to my search for daisy-chainable DisplayPort displays. However, before I cave and spend $179 on this device, I am wondering if this will be similar to other splitting devices where it appears to the computer as one big monitor and the device does the splitting (which I don't want). Or, does this use the packet-based nature of DisplayPort to present two/three separate displays to the computer? Also, would this device work on my MacBook Pro? (I know the Dell site says it's for Windows, but it also says that no driver installation is required. I'd assume since the MBP supports DP 1.2 it would work, but it's better to ask). Thanks! Edit: I've checked out the similar-looking Cirago DisplayPort splitter, but I have extreme doubts as to whether or not it's a genuine displayport splitter, or just another monitor-conglomerate. Their DVI solution looks identical to Dell's, which I'm pretty sure won't do what I want. I also don't want to order this DisplayPort "hub" and find that it doesn't do what I want it to.

• How do I get a UIView to appear instantly?

  - by matsgrip

  I'm trying to create an activity indicator in iPhone app. The problem is that I cannot get it to appear before the actual task i want it to diplay during is already done. Is there something funky about the order in which the iPhone does stuff? Here is my problematic code (in my app delegate): -(BOOL)showProgressView: (NSString *) message { self.progress = [[UIView alloc] initWithFrame:window.frame]; UIImageView *img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"squircle.png"]]; [img setAlpha:0.5]; [img setFrame:CGRectMake(94, 173, 133, 133)]; UIActivityIndicatorView *spinner = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(51.5, 51.5, 30, 30)]; spinner.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge; [img addSubview:spinner]; [self.progress addSubview:img]; [spinner startAnimating]; [img release]; [spinner release]; [window addSubview:self.progress]; return YES; } I then call this code like this: if ([appDelegate showProgressView:@"Loading..:"]) { //My actual code loads data and stuff here but that is not important //drawCtrl is a UIViewController subclass that is instantiated here UINavigationController *navController = [appDelegate navigationController]; [navController pushViewController:drawCtrl animated:YES]; [drawCtrl release]; } The problem is that my activity indicator does not appear until the new view controller is pushed onto the navController's stack. Can I control this in some way? Thanks in advance! -Mats

• Netcat file transfer problem

  - by thepurplepixel

  I have two custom scripts I just wrote to facilitate transferring files between my VPS and my home server. They are both written in bash (short & sweet): To send: #!/bin/bash SENDFILE=$1 PORT=$2 HOST='<my house>' HOSTIP=`host $HOST | grep "has address" | cut --delimiter=" " -f 4` echo Transferring file \"$SENDFILE\" to $HOST \($HOSTIP\). tar -c "$SENDFILE" | pv -c -N tar -i 0.5 | lzma -z -c -6 | pv -c -N lzma -i 0.5 | nc -q 1 $HOSTIP $PORT echo Done. To receive: #!/bin/bash SERVER='<myserver>' SERVERIP=`host $SERVER | grep "has address" | cut --delimiter=" " -f 4` PORT=$1 echo Receiving file from $SERVER \($SERVERIP\) on port $PORT. nc -l $PORT | pv -c -N netcat -i 0.5 | lzma -d -c | pv -c -N lzma -i 0.5 | tar -xf - echo Done. The problem is that, for a very quick second, I see something flash along the lines of "Connection Refused" (before pv overwrites it), and no file is ever transferred. The port is forwarded through my router, and nmap confirms it: ~$ sudo nmap -sU -PN -p55515 -v <my house> Starting Nmap 5.00 ( http://nmap.org ) at 2010-04-21 18:10 EDT NSE: Loaded 0 scripts for scanning.

Interesting ports on 74.13.25.94: PORT STATE SERVICE 55515/udp open|filtered unknown Read data files from: /usr/share/nmap Nmap done: 1 IP address (1 host up) scanned in 2.08 seconds Raw packets sent: 2 (56B) | Rcvd: 5 (260B) Also, running netcat normally doesn't work either: squircle@summit:~$ netcat <my house> 55515 <my house> [<my IP>] 55515 (?) : Connection refused Both boxes are Ubuntu Karmic (9.10). The receiver has no firewall, and outbound traffic on that port is allowed on the sender. I have no idea what to troubleshoot next. Any ideas? P.S.: Feel free to move this to SO/SF if you feel it would fit better there.
