  • ZigBee Maximum Bandwidth

    - by Kris
    What is the maximum rated bandwidth for ZigBee? I can't seem to find this information anywhere, not even on the ZigBee Alliance website at http://www.zigbee.org/ I did find some information elsewhere, but it dated back to 2004, so I'm guessing it's different now that it was 5 years ago. Thanks!

  • Linux: close a program with command line (not kill it)

    - by CodeNoob
    Some applications only allow one running instance (like eclipse, if you want to use the same workspace). So if I log in from another location, I have to kill/close the application that was open when I previously logged in from another location. I always use kill command to kill the running process. But, if you kill a process, it might not save some states that are useful for future usage. However, if you "close" it properly byclicking on the close button, for example, it will save the states properly. Is there a way to properly "close" an application from command line? I know this can vary from applications, so let's be a bit more generic: how to send a signal to another running application, and this signal works just as if we click the "close" button in the top bar? thanks!

  • GNOME 2 + Compiz equivalent?

    - by virtualeyes
    Running Fedora 14 and realize I need to either change distros or find an alternative to GNOME 3 in Fedora 17. Based on what I have read to-date, XFCE and KDE are the go-to WMs if I want to avoid GNOME 3. I tried KDE 4 and I wasn't impressed; I like the simplicity of GNOME 2 with Compiz and Emerald. Can't stay on Fedora 14 forever, however, so...where to turn? Basically looking for these features in my desktop environment: GNOME Do or equivalent Snap to grid/Window tiling A must-have, the ability to hot key focused window to a monitor grid region is a huge productivity win. Zoom window to cursor In a multi-monitor setup sometimes it's nice to, say, GNOME Do terminal in one monitor and then hot key the opened window to the other monitor just by zipping the mouse cursor anywhere on target monitor (followed by, of course, snap-to-grid hotkey, all without a single mouse click) Polarization At night white background hurts the eyes, so I prefer to hot key polarize to black. Multi-monitor support I'm partial to Fedora given that I've worked with CentOS for years and have little experience with any other Linux distro; however, if the difference between Fedora and Arch, Mint, etc. is fairly subtle, I'll make the leap, just need a distro & desktop environment that allows me to be productive with keyboard hot keys and provides the above basic features. Any suggestions?

  • Environment variables in bash_profile or bashrc?

    - by Viriato
    I have found this question [blog]: Difference between .bashrc and .bash_profile very useful but after seeing the most voted answer (very good by the way) I have further questions. Towards the end of the most voted, correct answer I see the statement as follows : Note that you may see here and there recommendations to either put environment variable definitions in ~/.bashrc or always launch login shells in terminals. Both are bad ideas. Why is it a bad idea (I am not trying to fight, I just want to understand)? If I want to set an environment variable and add it to the PATH (for example JAVA_HOME) where it would be the best place to put the export entry? in ~/.bash_profile or ~/.bashrc? If the answer to question number 2 is ~/.bash_profile, then I have two further questions: 3.1. What would you put under ~/.bashrc? only aliases? 3.2. In a non-login shell, I believe the ~/.bash_profile is not being "picked up". If the export of JAVA_HOME entry was in bash_profile would I be able to execute javac & java commands? Would it find them on the PATH? Is that the reason why some posts and forums suggest setting JAVA_HOME and alike to ~/.bashrc? Thanks in advance.

  • Can't create new folder from anywhere in Windows 7

    - by ymasood
    I have this problem on two of my new laptops and can't seem to find a decent workable solution elsewhere in forum land. The problem is that on my Windows 7 Professional machines the right mouse button doesn't show the New Folder option and elsewhere as well (via Explorer) I'm unable to create new folders. I'll be happy to get this tiny problem resolved and declare that Windows 7 is almost perfect! Thanks to all of you in advance for your contribution! PS: None of the Vista solutions seem to work here!

  • How to remove 'ApacheMonitor.exe' from notification area

    - by ekaj
    For some reason I had 2 instances of Apache running, and I have no idea how. I also had two instances of ApacheMonitor.exe showing in the "Notification Area Icons" place when you right click on your taskbar and go to properties. To fix the multiple instance issue, I deleted Apache completely and uninstalled the service (I did not use the .msi, I install from a .zip). Anyways, Everything from Apache is gone except the two things in the Notification Area Icon page. Does anyone know how to remove these two icons? I have completely uninstalled Apache, cleaned my registry with CCleaner, and rebooted. Does anyone have any other suggestions? Despite what the picture says, I do NOT have Apache installed, and it is not running.

  • Is there a way to allow continuous scrolling in Adobe Reader?

    - by RLH
    I am having to read through a MASSIVE (1000+ page) PDF specification in Adobe Reader X (version 10). It has always bugged me that if you scroll to the edge of a page, the Reader automatically jumps to the top of the next page. Is there away to cut this off so that when I reach the bottom of one page, the edge of the page meets the top of the next page and I can see a half-page of both the last and next page? I know that MS Word can and does behave this way. Can I change a setting to scroll the document in this manner in Adobe Reader?

  • Is there any way to customize the Windows 7 taskbar auto-hide behavior? Delay activation? Timer?

    - by calbar
    I'm becoming increasingly frustrated with the way Windows 7 handles showing a hidden taskbar. It's incredibly over-eager to pop out and obscure what I'm really trying to interact with, requiring me to move the mouse away, wait for it to auto-hide again, then resume what I was doing but more deliberately. After closely examining the behavior, it appears that a hidden taskbar "peeks out" from the edge by 2 or 3 pixels, and slowly moving your mouse into this area activates it; you don't even need to touch the edge of the screen. I would love it if there was a way to customize or change this behavior. Ideally, the taskbar would only pop out if you are actively "pushing" the edge of the screen it is hidden on. So activation only occurs once you've reached the screens edge and continue to move the mouse past a customizable threshold. Alternatively, a simple activation delay would suffice as well. So only if the mouse remains in that 2-3 pixel area (a.k.a. on the taskbar) for greater than a customizable amount of time does it pop out again. This would only be a fraction of a second. Often times the cursor simply "careens" off the edge of the screen while trying to focus on something nearby. Anyway, if there are any registry settings or utilities that can achieve either of these effects, that would be great! Thanks for your help.

  • Convert a Linksys WAG54GP2 ADSL router into Access point only to extend my Wifi range

    - by Preet Sangha
    I have a wireless lan running on my ASDL2 connection. The router (Seimens Gigaset sx763) is provided by the ISP and is generally good. However I have couple of dead spots at the far end of the house and since I have my old router sitting in the drawer I thought that I'd try to convert it into simple WAP. However downloading the manual from linksys it seems to be that the manual is from an earlier firmware, but the very first option on the very first page seems promising: Wan Mode: Router or ADSL However after this I'm a bit lost. I know that the wireless card on this box will need a mac address and it must get its address from the master router (I thought static might be best). However the again the manual is out of date I have the option of DHCP: ON or OFF or RELAY I've not even got to the more complex options yet. Question is can this device even work this way (seems like it but I cannot find any docs on it), and if so how? Edit: Having now fiddled around I'm of the opinion that this cannot be done.

  • why can't I open a port on Win 7? is it the app's fault?

    - by rjnagle
    I am having problems opening a port from one Windows PC on my local network. On Windows 7 computer ("Computer A") I running Calibre, an ebook management program that has something called an "ebook content server" . In essence, it serves via the web a content catalog. From Computer A, I can access the content server on localhost. ie. http://127.0.0.1:8787 calls up the content server successfully. With ipconfig I have confirmed that its local IP address is 192.168.1.106 From Computer B (a Vista Machine) I can ping 192.168.1.106 I have tried opening/editing a port in the Windows Firewall several times. In Windows firewall -- Allowed Programs in Control Panel, I see a listing for Calibre (with both Home/Work and PUblic checked) In details, I see Name: Calibre, Port Number 8787, Protocol TCP If I use the Advanced Security configuration screen for the firewall, I created an Inbound Rule on Computer A for Calibre (with the settings I indicated). If I run this command line on Computer A, I see: netstat -a -n TCP 0.0.0.0:554 0.0.0.0:0 LISTENING TCP 0.0.0.0:664 0.0.0.0:0 LISTENING TCP 0.0.0.0:2869 0.0.0.0:0 LISTENING TCP 0.0.0.0:3306 0.0.0.0:0 LISTENING TCP 0.0.0.0:5357 0.0.0.0:0 LISTENING TCP 0.0.0.0:6570 0.0.0.0:0 LISTENING TCP 0.0.0.0:6580 0.0.0.0:0 LISTENING TCP 0.0.0.0:8787 0.0.0.0:0 LISTENING TCP 0.0.0.0:10243 0.0.0.0:0 LISTENING TCP 192.168.1.106:63020 74.125.227.51:80 TIME_WAIT TCP [::]:80 [::]:0 LISTENING TCP [::]:135 [::]:0 LISTENING TCP [::]:443 [::]:0 LISTENING TCP [::]:445 [::]:0 LISTENING TCP [::]:554 [::]:0 LISTENING TCP [::]:2869 [::]:0 LISTENING TCP [::]:5357 [::]:0 LISTENING TCP [::]:6570 [::]:0 LISTENING TCP [::]:6580 [::]:0 LISTENING TCP [::]:10243 [::]:0 LISTENING TCP [::]:49152 [::]:0 LISTENING TCP [::]:49153 [::]:0 LISTENING TCP [::]:49154 [::]:0 LISTENING TCP [::]:49155 [::]:0 LISTENING TCP [::]:49170 [::]:0 LISTENING And lots of other junk, but this seems relevant, I see port 80 is open (I run xampp apache web server for windows on Machine A) This is the only time I see port 8787 referenced from the netstat commmand. From Windows Computer B, I can, ping 192.168.1.106 and even view http://drupal.local (on Computer A) and http://192.168.1.106/ (which goes to the Xampp config screen on Computer A). But I cannot access via Computer B htttp://192.168.1.106:8787 or htttp://computerhosta:8787 So what is going wrong? Is this a problem with the Calibre application or have I incorrectly opened the port? What things could possibly interfere with the opening of this port? On a sidenote, I have tried using telnet from Computer B to see if port 80 or 8787 is open for 192.168.1.106. I get no reply for either one. Thanks.

  • External Hard-Drive Randomly Ejects; Stays On

    - by Kaleb F.
    My 250GB I/O Magic USB external hard-drive randomly disconnects / ejects from the computer after between 2-30 minutes of use. When this happens, the blinking activity light on the front of the hdd turns off; however, the disks can still be heard spinning. Unplugging & replugging in the USB does not reconnect the device and the activity light remains unlit. The only way to continue using it is to flip off then on the power switch of the hdd. The hard-drive was formatted with MBR partition table and 2 NTFS volumes. I recently tried switching to GUID with two Mac OS Extended (Journaled), but the problem remains. This error occurs with my new Macbook Pro with Snow Leopard as well as with my DELL E520 with Windows 7 Ultimate.

  • Eclipse grinds to a halt when building workspace

    - by Chris Thompson
    Hi all, This is a bit of a vague question because, frankly, I don't even know where to begin diagnosing the issue. My eclipse (Galileo) installation grinds to a complete halt when it's building the workspace -- to the point where I can't even type. I know the Android SDK I have installed is a major culprit because I can watch the memory usage go through the roof (through the built-in heap monitor) when the Android SDK content loader starts up. Every time I save a file though, the program just stops. The message at the bottom of the screen says Building workspace (74%) and sits there for about 30 or so seconds before completing and returning the performance to normal. I have a few other plugins installed (Maven, SVN, etc) but I'm assuming the main issue is Android. Has anybody had similar issues or any luck correcting this sort of problem? If there's anymore information you think would be helpful, just let me know...I didn't want to do a core dump on this question... I'm running it on Windows 7 64-bit for what it's worth. Thanks! Chris

  • USB ports causing Wireless and Mobile Phone tethering drop out

    - by chrolli
    I have a problem with my USB ports and I can't seem to pinpoint the problem. I'm hoping that I can get some idea as to how to troubleshoot my problem. Problem description: I recently bought a USB Wireless Adapter in order to connect my Desktop PC to the WLAN. The dongle keeps dropping off connection regularly on average once a minute. And the connection is slow. What I've tried: I installed a network scanner to determine signal strength. The PC/adapter combo is getting about 70% signal strength. I have a laptop that has an internal Wireless adapter. I moved the laptop near the location of the PC. The signal strength was above 90%. I installed the USB adapter on the laptop. I placed the laptop near the location of the PC. The signal strength was above 80%. And there is no drop out issue. I've isolated the problem to be on the PC. I used internet tethering on my mobile phone in order to test the USB ports. I get the same problem, themobile phone keeps dropping in and out. I plugged the adapter and phone on all USB ports, and it is still dropping out on all ports. I've isolated the problem to be the Motherboard, USB hub. I updated the BIOS, and USB driver. Still dropping out. I noticed that when I used the mobile phone tethering method, the phone (iphone 5) is guarenteed to drop out and does not appear to charge if I jiggle the the 8-pin connector on the base of the phone. If I push the pin tightly on the phone, the phone starts charging, as soon as I let go, it stops and drops out from the PC. This is strange because this doesn't happen when it is plugged to the powerboard. Which means that the 8 pin connector is fine. I'm not sure what the problem is. I assume that it is to do with the USB ports not supplying enough power which in turn causes the devices to intermittently drop out. The reason I say this is because the USB cable works fine when plugged into a powerboard with enough power supplied to the phone. Only when it is plugged into the USB port on the PC, does it drop out. My motherboard is Asus P8z68-v le. My Wireless adapter is the D-link DWA131. I can't seem to find any settings in the BIOS to increase the south bridge voltage so as to supply more power to the USB ports. Although this problem only occurs when I'm trying to hook up to a device supplying internet connection. My USB HDD, Flash drives, and Mouse and Key are working fine! Any suggestions please?

  • Why is my ogg bigger then my m4a?

    - by acidzombie24
    i am using ffmpeg.exe -i 0123456789 -ab 192k out.m4a ffmpeg.exe -i 0123456789 -f wav - | oggenc2.exe - -r -q 6 -o out.ogg (0123456789 has no extension). My m4a output is 14,608kb while my ogg output is 19,809kb why? AFAIK -q 6 is roughly 192kb. So it should be about even. I could see one file being 1-3mb bigger then the other but 5 is pretty large. the m4a is almost 75% of the ogg! thats a lot! Why is this?

  • Cannot set up dual monitors correctly in Fedora15 with KDE.

    - by adivasile
    I have 2 monitors: 24" LCD connected via DVI(primary) 19" LCD connected via VGA(secondary) Everytime Fedora starts the second display is always set to clone the first one and they both run at 1280x1024 and I always have to disable the 19" monitor, in order for the bigger one to run at 1920x1080. I want to set them up so that my secondary monitor extends the primary one.The problem is that no matter what kind of configuration I choose it has no effect.My secondary monitor remains disabled. I've tried using both the Display manager from KDE and the ATI Control Panel and the behaviour is always the same.The moment I click apply, the screen flickers and nothing changes. I've succesfully used the extended setup in Fedora15 with Gnome3. I have a RadeonHD 4300 series videocard and I'm using the drivers downloaded from the AMD site. This is the output of xrandr -q : Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1920 VGA-0 connected (normal left inverted right x axis y axis) 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1024x768 75.0 70.1 66.0 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 75.0 72.8 66.7 59.9 720x400 70.1 DVI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 60.0 1680x1050 59.9 1600x900 60.0 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1280x720 60.0 1152x720 60.0 1024x768 75.0 60.0 832x624 74.6 800x600 75.0 60.3 640x480 75.0 59.9 720x400 70.1 Later edit: The problem seems to come from the ATI drivers.I managed to set up the monitors like I wanted after I uninstalled the drivers. Unfortunately I'm working on an OpenCL project so I had to reinstall them.The moment I did that, all my previous settings were forgotten and I was back to square one.

  • Restoring open software after a restart event in windows

    - by Doltknuckle
    I find that at the end of a long day, I sometimes have a large number of programs running. All which I will need to use tomorrow. Normally, this isn't an issue, I can simply lock the machine and come back tomorrow. My problem arrises when windows update launches in the middle of the night and force restarts my computer. That in turns closes all my open software. I of course save everything regularly so I don't loose anything, but I waste time reopening all of those resources whenever there is a restart. [EDIT] I should clarify that I still want to be able to restart my computer when an update comes down. Preventing the restart only delays the problem until later. I should have been more specific in that I want to be able to recover my working environment after a restart for any reason. Things like scheduled maintence, power loss, updates, and software installs. [EDIT] I can't simply have them setup to launch at startup becasuse those files change from week to week. So I need something that monitors what I have open, and gives me the option to "recover" those software sessions when I log back in. Anyone have any suggestions on what I can do? I'd even be willing to purchase software to do this for me if that is the only option. Thanks
