• Sound quality in bluetooth headphones doesn't change to high

  - by Sergiy Byelozyorov

  My Bluetooth headset Philips SHB6610 has several profiles. It can work as low-quality headset (HFP) and high-quality headphones (A2DP). I mean sound quality. Typically whenever I start to play the music in my media player it works in high quality, while if I receive a call on Skype it switches to low-quality. Once call is finished it falls back on high quality again. However, from time to time, it happens that I connect headphones to the computer and they just stay in low-quality mode. I don't know how can I change the profile manually, since it was always done automatically so far. The only thing that helps (but not always) is re-pairing of headphones with PC. I am using Windows 7 on Toshiba Satellite Pro P300-1CG laptop, with Belkin Mini Bluetooth Adapter.

• Email etiquette checker?

  - by Benjamin Oakes

  Sometimes, in the heat of getting a lot of things done, I don't read emails I send as closely as I should. Is there an automated way to pop up warnings before a potentially-unpolite email is sent? I'm thinking about something that would say "wait, why don't you have a 'please' or 'would you' in that message?" I'm using Thunderbird 2 on Ubuntu 9.04. I may be willing to switch email clients if another program offers this. Thanks for your help!

• How to fix corrupted filesystem (shows as RAW) in USB device?

  - by Erico Yan

  I would like to ask if you know how to fix a corrupted USB? I've tried the diskpart command but it didn't work. The media is write protected. Do you have any idea that is much better? I need to fix it because I have important files in my flash drive. I really need to retrieve it. I saw that the file system is seen as RAW and is unaccessible. I tried error checking, but it requires you to format it. I tried data recovery software but all files come out corrupted. My USB is Imation 4GB. Any suggestions?

• Can I run iOS apps on my Mac?

  - by Ken

  I've seen a number of neat iPhone apps recently that I'd like to use. In particular, there are a number of neat musical apps (metronome, tuner, etc.) that seem highly rated, and have no real Mac equivalent. I don't have a recent iPod/iPhone/iPad (I don't need portability or a phone and it seems silly to pay hundreds of dollars to run $15 worth of apps), but I do have an Intel (C2D) Mac. Can the iPhone dev simulator, or any other emulator, download and run iPhone App Store apps?

• VMware Workstation Recording feature

  - by Steeve

  I have seen some documentation about a Record/Replay feature in VMware workstation 6 and 7 here : http://cto.vmware.com/the-amazing-vm-recordreplay-feature-in-vmware-workstation-6/ http://www.vmware.com/pdf/ws65_manual.pdf But I don't find that feature in my VMWare Workstation 10. I don't find any manual for the 10th version by the way. Do you know if that feature has been removed ? Or do you know where I can find the feature in VMware Workstation 10 (or 9) ? Thanks in advance,

• How to find and diagnose poorly-performing Firefox addins?

  - by Scott Bilas

  I use a lot of addins in my Firefox. One of them is causing periodic freezes when watching video. Super annoying. Aside from doing a binary search of disabling addins to narrow down the problem (which would take a very long time due to frequency of the freezes), are there any other options? If the problem came from the native app, then I'd just load up a profiler and see where the time is going. But it's all in Javascript. Are there any tools that exist to help figure this out? Maybe some instrumentation I can throw on a few key source files in a local build to help diagnose the problem?

• Best free (or cheap) ASP.NET based CMS for a club/association?

  - by marc_s

  I've been looking for a simple, intuitive ASP.NET based CMS to handle my club/association site. It should be based on ASP.NET so I can add some extra specific pages offer a membership system, e.g. I want to be able to define members which can e.g. comment posts, while anonymous users can only read (no active participation) have features like news, forums, blogs, picture gallery be simple and easy to use I've been looking at GraffitiCMS: so far my favorite, but it has no forum, and no membership system, and no future, it seems - no development whatsoever in over a year :-( Sitefinity: had extreme trouble even getting it installed, and when it's finally up and running, I find it overly complicated and not intuitive at all Umbraco: same problem - hard to install, hard to get up and running, the intro videos on their site are only available to paying subscribers (what's up with that deal???)..... DotNetNuke: seems like a major overkill Community Server: seems like a major overkill - and seems to be more and more commercial, only Any others I've missed that I should have definitely looked at ??

• iptables openvpn forward selectively from eth to tun

  - by Bryan Hunt

  Simple for those who know, indecipherable for those who don't... I'm running openVPN on (hypothetical) 66.66.66.66, I want to FORWARD incoming traffic, arriving on interface eth0 to interface tun0. It would also be nice to filter - based on destination IP address. I'm doing the NAT later on, but like to lock down early wherever possible. So onto the main course... This works: #Enable forwarding from eth0 to tun0 iptables -A FORWARD -i eth0 -o tun+ -j ACCEPT But this doesn't pass any packets whatsoever: #Stricter version iptables -A FORWARD -i eth0 -o tun+ --dst 66.66.66.66 -j ACCEPT Am I being unacceptably foolish?

• Intel P6100 CPU and Mobile Intel® HM55 Express Chipset

  - by Christopher Painter

  I have an Asus K52F-BBR5 notebook that uses an Intel P6100 ( 2GHZ 15x multiplier) and HM55 Express Chipset. I'm looking to replace it's 3GB with 8GB. The Crucial database seems to indicate that a PC3-8500 CAS 7 and PC3-10666 CAS 9 will both work. I'm not up to date on the latest DDR3 nomencalature and I'm wondering which would provide better performance. The price difference is negligible. Drawing on past experiences from many many years ago I could make an argument for either based on sync/async bus speed arguments and CAS latency differences but the truth is I don't know enough about the HM55 chipset to know which would be the correct choice. Does anyone know the answer or point me to information that would help me make the choice? I'm pretty sure the performance difference will be somewhat negligible also but still I'd like to make the optimal choice.

• eMachine W5243 won't POST; fans run but optical drive will not open.

  - by NicciAdonai

  Symptoms are what is described in the title. The machine reacts to the power button being hit by spinning up the two fans: CPU and PSU. The hard drive (SATA) spins up as well. No other reaction. This one symptom is particularly weird, though: the optical drive will not open with the IDE cable attached, but if I unplug it from the mobo it will. I can turn the PC on with it attached, won't open; then unplug IDE while it is still on, WILL open; then plug IDE back in with the PC STILL ON, WON'T open. I have disconnected every peripheral unnecessary to POST. These include: mouse/keyboard, PCI modem, the IDE optical drive (power and data), and the SATA HDD (power and data). Video is onboard. The only two things connected are DB15 video and power cable. There were 2 512 MB DDR2 sticks of RAM in it. I have tried running it with just one of them, then switched the other in. Currently seated is a completely different 1 GB stick that I keep around for troubleshooting purposes, and I have tried it in both slots. I have replaced the CMOS battery with a used one I had lying around, and which worked in the computer it came out of. I have tested the PSU with a tester to confirm it was good, then tried connecting another PSU just in case--same symptoms. I have even tried a suggestion I found elsewhere on this site wherein one disconnects power from the PSU and then presses the PC's power button twice, thereby "resetting" the PSU. Currently I am trying yet another suggestion: turn it on and wait an inordinate amount of time for POST. Any help would be appreciated.

• ffmpeg hangs when creating a video

  - by FearUs

  I am trying to insert an audio channel with a video: first of all I extract the audio from the original video for processing: ffmpeg -i lotr.mp4 lotr.wav I then extract all frames for later processing too: ffmpeg -i lotr.mp4 -f image2 %d.jpg When done processing audio and video streams, I try to create the video ffmpeg -f image2 -r 15 -i %d.jpg new.mp4 then merge with the audio: ffmpeg -i new.mp4 -i lotr.wav -map 0:0 -map 1:0 new_w_audio.mp4 Result: CPU activity = 100%, the process hangs and never returns.

• Vertex 2 SSD is running faster than my Vertex 3 SSD?

  - by Kairan

  I used Acronis Disk Director to do a direct clone of my C:\ windows 7 x64 drive from my Vertex 2 to my new Vertex 3 SSD (Just to show the drive software winstall everything is identical.) I ran a performance test on Windows using the Windows Experience Index. The rating I am receiving when booting on the Vertex 2 is 7.5 While I am getting only a rating for the Vertex 3 of 6.9 My understanding is that the read/write speeds of the Vertex 2 is only up to 250MB/sec while the Vertex 3 is up to 500MB/sec. Copying a single file (3GB in size) from the Vertex 3 to itself was getting speed of approx 70-80MB/sec This speed is no better (maybe worse) than what I got from the Vertex 2 I am connected via the SATA 3 port on the motherboard, using an SATA 3 cable Is this issue caused by the drive cloning? Do I have a bad SSD?

• Start script on network connect

  - by Nate Mara

  I am trying to get a GNU/Linux Bash script to run as soon as a network connection is established on my Raspberry Pi. I tried following the instructions on several pages: I have tried adding my script to /etc/network/if-up.d and running sudo chmod ugo+x on the file. I have tried adding the line post-up <path/to/script.sh> to /etc/network/interfaces I am really quite clueless here. More info: The script runs fine when manually run, here it is: http://pastebin.com/UJvt5HYU (I did remove my personal info (email addresses, passwords), but other than that, the script is unchanged. This script also uses the sendEmail program (can be found at http://caspian.dotconf.net/menu/Software/SendEmail/).

• A Firefox extension for scan & upload document?

  - by Ivan Petrushev

  Hello, Do you know such an extension that provides easy document scanning in Firefox? We are building a web site and we want visitors to be able to upload scanned documents to it. The normal procedure for that is: Scan the document via Gimp, Photoshop or some other scanning software. Save the file. Navigate to the upload web page. Find some sort of HTML input type file on that page. Browse and find the saved file. Submit the form. I want an extension or plugin that automatize that process and do everything with 1 click - scan the document with some default settings (for example "grayscale, 300 dpi") creates temporary file, fills the page input field and deletes the temporary file after upload. I tried lots of googling but the term scan in combination with everything web-related gives zillions of virus, malware and port scanners...

• How do I fix this Windows 7 wireless connectivity issue?

  - by Charles Randall

  I have a laptop with an Intel Wireless Centrino 6300 module. Recently, the machine has stopped properly connecting to my wireless router. It will get stuck in a loop of connecting, then disconnecting and reconnecting. While connected, it will simply say "No Internet Access." Running inSSIDer 2.0, it shows my network jumping around between two channels -- I know this isn't the case, because I've set my router to sit on one single channel. My MacBook Pro, Boxee Box, PS3, and Xbox 360 all connect fine to the wireless and have no problems at all. I know it's not the wireless module, as I bought a second one recently assuming the first had died -- but I get the same behavior with both. Sometimes, I can fix the issue temporarily by deleting the network (Using the Manage Wireless Networks page), and then re-adding it (via standard wireless methods). Then it will work for a few days. But inevitably the problem comes back, and now the laptop simply won't connect to the wireless at all, even if I take steps that usually work. Since I've ruled out the hardware, and it's unlikely some kind of interference issue (because I would expect to see it on any multitude of other devices), I would think at this point that it's a problem with Windows itself. One thing that might be a hint, even though I delete the network, when I add it again, it's always listed as "Wireless Network Connection 2" even though there isn't another in the list.

• How do I convert a Linux disk image into a sparse file?

  - by endolith

  I have a bunch of disk images, made with ddrescue, on an EXT partition, and I want to reduce their size without losing data, while still being mountable. How can I fill the empty space in the image's filesystem with zeros, and then convert the file into a sparse file so this empty space is not actually stored on disk? For example: > du -s --si --apparent-size Jimage.image 120G Jimage.image > du -s --si Jimage.image 121G Jimage.image This actually only has 50G of real data on it, though, so the second measurement should be much smaller. This supposedly will fill empty space with zeros: cat /dev/zero > zero.file rm zero.file But if sparse files are handled transparently, it might actually create a sparse file without writing anything to the virtual disk, ironically preventing me from turning the virtual disk image into a sparse file itself. :) Does it? Note: For some reason, sudo dd if=/dev/zero of=./zero.file works when cat does not on a mounted disk image.

• How to access programs in one PC using another PC

  - by darkstar13

  Hi, I was recently given an old PC for my remote access at work. The CPU that comes with it has Windows XP installed, 400+ MB of ram, all USB devices disabled. I access my work applications using VPN / Citrix. Basically, it' sooooo slow. Plus it's bulky and it will just occupy space, so I am now hoping to find a way for me to integrate this work PC with my home PC. I tried to put in the hard drive in my home PC CPU, and set the drive as slave. However, when I booted my PC from this hard drive, I am stuck at the screen where windows is prompting me to select how am I going to boot (ex. Safe Mode, Safe mode with command prompt, Last Working Configuration, etc), but whatever option I select, I am still stuck at this option after reboot. I am thinking if maybe I can clone the drive and mount the cloned drive and access the system as a virtual machine. But I don't know if that will work. I would like to know if there's something I can do so I can work at home using my home PC, where I can access my work programs to connect to VPN / Citrix. My home PC's OS is Windows 7 Ultimate x64.

• Force netsh/arp binding multicast IP addres with specific MAC address

  - by Olivier

  I would like to setup an binding from an IP address to a MAC address using netsh. Goal is to bond an IP address which is a multicast address (224.224.x.y) to a given MAC address (which is NOT the calculated one from the multicast IP address : 01:00:5e:X:Y:Z It used to work with Windows XP (was it a bug that used to be "perfect" for my needs?), but Windows 7/8/8.1 forces the MAC address to the calculated one instead of letting me put what I want! (http://nettools.aqwnet.com/ipmaccalc/ipmaccalc.php shows MAC address calculation for multicast IP address) Thus I'm doing the following. Listing existing mappings: netsh.exe interface ip show neighbors "Ethernet" Interface 12 : Ethernet Internet address Physical address Type 224.0.0.22 01-00-5e-XX-YY-ZZ static Then adding my interface mapping manually: netsh.exe interface ip add neighbors "Ethernet" "224.xxx.yyy.zzz" "00-80-EE-UU-VV-WW" Finally, listing again my mappings: netsh.exe interface ip show neighbors "Ethernet" Interface 12 : Ethernet Internet address Physical address Type 224.0.0.22 01-00-5e-XX-YY-ZZ static **224.xxx.yyy.zzz 01-00-5e-UU-VV-WW static** As you can see, the MAC Address of the second entry (the one I just made) has been dynamically replaced by the calculated MAC Address corresponding to my IP Address... Calculation is done as follow (and displayed in hexa): UU=(xxx-128) VV=yyy WW=zzz But I don't want that behavior. My IP address and MAC address cannot be changed, and I must associate them accurately. Does anybody know how to disable MAC address substitution/calculation in netsh? Thanks, Olivier.

• How can I limit my data usage over tethering on Windows?

  - by Casebash

  The excess data charges if I go over my tethering data limit are ridiculously. Fennec already stated the question well. Because of this, and on general principle, I'd like to have some tools which permit me to do things like: Monitor the amount of bandwidth that I've used I think I can do this from Sprint too, but on-the-computer is nice too on-the-computer gives me a possibility of breaking it down by application See what sort of programs are using the Internet connection I could use, like, Wireshark, but that's a bit too micro-level to be practical Keep those programs, and the operating system, from doing things like "downloading an operating system update" while on the mobile hotspot Related I want to monitor and limit OS X's data transfer while I'm tethering via my iPhone

• local app opening instead of ssh forwarded app over x

  - by The Journeyman geek

  i have a custom install of ubuntu 9.10 - xorg intel and its deps, icewm, xde and swiftfox from the swiftfox repos. I'm trying to start a ssh forwarded session of swiftfox from another system - which has the plain vanilla firefox version in the repos- with ssh -x [ipaddress] and then starting swiftfox from command line. When i start it though, it opens up the local copy of firefox instead of the copy of swiftfox on the other box. I have NO idea what's wrong...swiftfox dosen't open on the remote box, i am definately on the remote boxes terminal, and there's no way whatsoever it should open a local copy. I'm wondering what's wrong

• How do I find out the Mac Address Firefox submits for Geolocation?

  - by Jim McKeeth

  I moved, but have the same router and cable box. Now when I visit Google Maps it still shows my old location. I went to the SkyhookWireless update page to update my Mac Address with my new location. The process is you put in your Mac address and it shows you the current location, and then you adjust that location and submit it. When I got the Mac Address from the status page on my router Skyhook reported that location as in Pakistan, which isn't even the correct continent (as my old or new address). I tried every other Mac address I could come up with: The cable router, the Wireless router's other Mac address, my PC's Mac address, etc. and none of them reported any location on the Skyhook page. So I am guessing that there is another Mac address, or some other bit of information that is used by Firefox when it reports to Google Maps my current location. Now that you have the back story, how do I find the Mac address or whatever information it is that Firefox (or other browsers) use to determine my Geolocation? Everything I have read online is rather vague. The next option I am considering is hooking a logging proxy onto Firefox and seeing what data it sends, but I'd rather find an easier method. Related: How do I update the geo location of my house?
