• How do you enable webcam support in Facebook for Ubuntu 10.04?

  - by Jonathan

  I think I have finally arrived at an insolvable equation: Chromium v.7 + Ubuntu 10.04 + Sun Java 6 + Webcam + Facebook + Flash 10 = non-functional All of those items listed above are potential points of failure in this situation, and any help narrowing them down would be fantastic. I am simply trying to enable webcame support directly through Facebooks website. Forum searches and the usual googling turn up few posts related to this specific equation. Two of the major suggestions include: 1) Installing the Sun (I refuse to say oracle sob)-provided Java implementation instead of the OpenJDK normally installed in Ubuntu. And yes, after installing it, I did update all my default supports to use the sun commands over the openjdk. 2) Somehow enabling Facebook as a permitted site to access my webcam using Flash settings. I have not been able to explore option 2 because I cannot find a way to adjust the Flash settings in chromium 7. Other factors that do not help include the fact that I am pretty sure facebook changes its webcam interface every 10 seconds just to keep troubleshooters and support personnel on their toes. If anyone has a OTP that informs us of the next shift in the app, a leak would be greatly appreciated!

• How can I optimize my ajax calls to deliver at 60ms.

  - by Quintin Par

  I am building an autocomplete functionality for my site and the Google instant results are my benchmark. When I look at Google, the 50-60 ms response time baffle me. They look insane. In comparison here’s how mine looks like. To give you an idea my results are cached on the load balancer and served from a machine that has httpd slowstart and initcwnd fixed. My site is also behind cloudflare From a server side perspective I don’t think I can do anything more. Can someone help me take this 500 ms response time to 60ms? What more should I be doing to achieve Google level performance? Edit: People, you seemed to be angry that I did a comparison to Google and the question is very generic. Sorry about that. To rephrase: How can I bring down response time from 500 ms to 60 ms provided my server response time is just a fraction of ms. Assume the results are served from Nginx - Varnish with a cache hit. Here are some answers I would like to answer myself assume the response sizes remained more or less the same. Ensure results are http compressed Ensure SPDY if you are on https Ensure you have initcwnd set to 10 and disable slow start on linux machines. Etc. I don’t think I’ll end up with 60 ms at Google level but your collective expertise can help easily shave off a 100 ms and that’s a big win.

• How can I automate or script daily downloads for any new anti- virus databases, and then have the program scan my drive?

  - by Macgrimm

  Howdy all Super Users" I humbly ask if any Super User can direct this long time, gray haired Apple Tech in the right direction on this issue. I believe there probably are many ways to skin this cat. But I am looking to find simply the best, most unattended way to get it done. Any help will be greatly appreciated. also (I know there are much better softwares out there for the Mac so please don't go there! The politics of this company dictate which Anti virus we have to use) anyway without any further wait: basically I am trying to automate 2 very important functions of Mc'Afee anti-virus for Mac. First I want to automate the process of retrieving new virus definition files, and second I want to automate the process of scanning for viruses. It turns out that Using Mc'Afee Anti-Virus for the Mac are both manual functions. And they left up to the user (per user account) to perform. Depending on all of about 150 MAc users to perform these 2 tasks themselves is around 65% compliance. My question then is: If I wanted to use the command line such as (open /Applications/McAfee\ Security.app) It will open up the Security Console. But how can I make command Mc'Afee go out and grab the definition files and scan the computer? I have to admit I am at a crossroad and Macaltimers has set in. I would really appreciate it if any of you "Super ~ Users" can help me out with this MacAltimers loss of how to what to do. Thanks to All up Front Macgrimm

• does leaving the laptop cord in break the cord?

  - by firedrake

  i recently got a new cord for my laptop because the cord i had before broke.im not sure how it got messed up, but one moment it charged my laptop and the next moment it didn't. i then got a new cord. the new cord worked perfectly fine until now, and it has only been a month. the cord wont work unless i am pressing it into the socket, which i am currently doing. the only thing i can find in common with the cords is that i leave them plugged in 24/7. my brother says that is the problem, but i do not think it is.any tips or hints? im going to use duct tape to keep the pressure on the cord till i can find a better solution(im also thinking it could be the hole i plug it into on the back of my computer, but im focusing on the other idea for now.if i wiggle the plug part in the socket of my computer it will stop charging unless im pressing it in or to the side) any help or ideas are appreciated. not sure if this will help but i use a gateway with windows vista. thanks

• Have to run auto-negotiate between clients and switch - "old" switch works fine - "new" switch results in "port flapping"?

  - by ConfusedAboutSwitching

  I need some help understanding a problem we're having at work: We run Altiris/Deployment Solution and have to use auto-negotiate between client systems and our switches (Altiris apparently requires this for imaging, PXE boot and other functions). We have several areas with old wiring (Cat 3 & Cat 5) that have old 10/100 Cisco switches in them - and we can set these systems up to "auto/auto" (auto-negotiate on both the NIC and the switch port), and everything has been working fine. But - our networking crew changed out a couple of old switches for 10/100/1000 Cisco switches, and now - they are claiming that "auto/auto" won't work because the switches can't auto-negotiate the way the old 10/100 switches did - and that if we try to set the new gig switches to auto-negotiate, the switch port starts "port flapping", and shuts the port down. But - if we put the old switch back in - they work using "auto/auto" just fine - no port flapping. The networking crew is telling me that the problem is that we're putting "new switches" on "old wire", and that the old cabling can't/won't support the auto-negotiation with these new switches....??? There's something about this that doesn't make sense to me - can someone explain this to me? Or is our networking crew just doing something wrong in the configuration of these new switches? While will the old switches work "auto/auto", but the new switches won't?? HELP!!....and Thanks!! M

• SNMP query - operation not permitted

  - by jperovic

  I am working on API that reads a lot of data via SNMP (routes, interfaces, QoS policies, etc...). Lately, I have experienced a random error stating: Operation not permitted Now, I use SNMP4J as core library and cannot really pinpoint the source of error. Some Stackoverflow questions have suggested OS being unable to open sufficient number of file handles but increasing that parameter did not help much. The strange thing is that error occurs only when iptables is up and running. Could it be that firewall is blocking some traffic? I have tried writing JUnit test that mimicked application's logic but no errors were fired... Any help would be appreciated! Thanks!

• How to fix Truecrypt MBR using Command Prompt or Linux live USB?

  - by Michal Stefanow

  I was playing with TrueCrypt and decided to make a fresh installation of Windows 7 from USB stick. Unfortunately Windows 7 installer: "setup was unable to create a new system partition" My entire HDD has been formatted and is visible as 320GB unallocated space, but no fdisk nor Windows 7 installer nor Windows XP installer could help. (Windows XP doesn't even see the HDD, it sees only USB stick and says "not enough space to install") It may be related to Truecrypt and pre-boot authentification, boot loader and/or MBR. As I don't have optical device I could not have created rescue disk. Right now I need a rescue of some kind, supposingly by erasing/fixing MBR using Linux live USB or using Command Promt. Another approach is to click "repair your comuter" menu from Windows 7 installer then click "restore your computer", then click OK upon error and get access to Command Prompt. Yet another another approach is to start computer without Linux USB I receive this: error:unknown filesystem. grub rescue> Any help would be greatly appreciated as my laptop is kind of not fully operational now. UPDATE: This was asked long time ago, ended up formatting everything (eventually it worked using different bootable USB)...

• Exporting only visible datagridview columns to excel

• Assembly Level Language? Unlock iPhone 3GS with latest Baseband. Need Opinion

  - by getkenny

  Hi Guys, So its more like advice i need. I got 2 iPhone 3GS (Bootloader 06.02 and BB 05.11) which are lying around useless cause it was bought it from US and now i am in Dubai. Cannot use the phone because there is no unlock. Now rather than waiting and relying on other people to provide a unlock for the baseband , i was thinking of learning what it takes to unlock a iPhone. I currently don't even know what i got to learn to do this. I understand from soem reading around that i will need to learn ARM to understand the baseband and try to find a exploit: is it correct? I really want to help people out in getting their iPhones working. Also the iPhones cost was $645 each (16GB) so its not like Apple is going to loose any money of it, the person who bought it for me thought that if your not buying with an AT&T contract it means that it is unlocked but it is not true. I need help, i am willing to learn and you guys are the best bunch around to give me advice. Regards.

• How can I create two partitions and clone one to the other (using Clonezilla)?

  - by johnny

  I was hoping someone could help. I want to create a "backup" partition. I want to create two partitions on my drive. One is a good install, which I want to then use clonezilla to copy the good partition to the broken/unused partition and have the restored partition boot up as usual. Example, C: goes bad. D: is a "good" copy of C. C gets a corrupt registry. I restore D to C, C will then boot up as usual. So, I need to do the clone with Clonezilla and the restore with the same. I see the part_...clone and restore. Will this do it? How do I get the partitions? EDIT: I am using XP. How can I do this? Also, I know this is not the best thing for all occasions. I have a offline backup as well. I would like to have both. Thanks for any help. I'm using Clonezilla if it matters.

• MySQL permissions error when showing databases

  - by Tony

  I was trying to install homebrew and very very stupidly did this: sudo chown -R $USER /usr/local The Homebrew instructions say to do this and I'm not much of a sysadmin so I took their word for it. Lesson learned (although I wouldn't really know how to test this...seems like an "undo" script would be super valuable here) Anyway, what is done is done, but now I get this error: $ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 548 Server version: 5.1.33 Source distribution Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> show databases; ERROR 1018 (HY000): Can't read dir of '.' (errno: 13) I tried chown-ing back to root with no avail. Does anyone know how I can fix this without reinstalling mysql? Optionally, if I have to reinstall mysql, how can I dump my databases without access to the command line so I don't lose all of my data. Thanks!

• Microphone doesn't work

  - by mandy

  I'm having a trouble with my built in microphone. Even if I use headphone with mic, it doesn't really work. The weird thing is, if I clap the green lines of the speaker icon jumps, but if I speak it doesn't. I have also tried some recordings, but I can not hear myself and adjusting the volume didn't help at all. I tried to restore it, still no change. I have updated it in the device manager, but it said there that it's up to date and the devices are working properly. Until I decided to recover the whole system (wherein I pressed zero and switch on button) to my surprise, the settings became different, most programs were deleted, even my files. It's like it was formatted and I'm so sad that the mic was not fixed. I really don't know what to do now. My laptop model is Toshiba satellite m840. I want to it return to its settings/set up just before I Recover the system and bring back all the programs that we're installed and of course, most of all, to fix my microphone so I can use Skype again and other video calling application.. I hope someone could help me. Thanks a lot!

• Windows XP - Power surge on hub port

  - by Swift-Tuttle

  Hi, Since last few weeks I constantly get this error, as status bar balloon: Power Surge on Hub Port - A USB device has exceeded the power limits of its hub port. Due to this now I am unable to access any USB devices properly, they get disconnected intermittently. I did quite a few things to resolve this problem, firstly obviously through the Windows help. I even tried all the things told on the Microsoft website(which essentially says is to check and update the driver) but in vain. One suggestion, I found when I google'd was to disable the USB2 controller through the Device Manager and since at every startup the System configuration comes up complaining that it has been changed etc.(On that same site it is mentioned to ignore this message.) But after everything I still cant solve this problem. Any help is much appreciated. The system is installed with Windows XP service Pack 3 and all the updates till last month. Please let me know if any other hardware info is required. **UPDATE** My laptop is about 5 years old now, its an HP with Celeron 1.4G processor. Windows XP SP3 installed. All latest windows updates installed. 2 USB ports available. BIOS is HP 68DTD ver F.0A Do I need to update my BIOS from somewhere ? or is this a hardware problem altogether?

• How to flash Dell Precision 390 from linux (debian)

  - by malat

  I am trying to update my BIOS: $ sudo dmidecode -s bios-version 2.1.2 With a newer one: 2.6.0. I went to this page Dell Precision System BIOS, 2.6.0 After downloading the file WS390-020600.BIN, here is what it states: $ ./WS390-020600.BIN --help Usage: WS390-020600.BIN [options] Options: --help Print this text. --version Print package versions. If no options, update the BIOS. and $ ./WS390-020600.BIN --version Dell BIOS Update Installer 1.2 Copyright 2006 Dell Inc. All Rights Reserved. ./WS390-020600.BIN: 60: ./WS390-020600.BIN: ./flash: not found Does anyone knows where this flash command can be found ? Update: it looks like this is a self-extracting archive (need bash as per comment in header). $ head -30 WS390-020600.BIN [...] Extract() { tail -n +`awk '/^__ARC__/ { print NR + 1; exit 0; }' $0` $0 | gzip -cd >$_PRG So the flash command should have been auto-generated, however the above command does not appear to be running as original author intended. I do not see anything wrong with the command though.

• Azure VM won't boot after sysprep; integration tools installed

  - by Mark Williams

  I have installed the Azure Integration Components and used sysprep on a Windows 2012 VM. Now the machine won't start up. I uploaded the VHD to Azure - it failed there too. When I start up the VM I get a PowerShell window that hangs out for a bit; eventually I get the following error, after which the machine restarts. New-Object: The dependency service or group failed to start. (Exception from HRESULT: 0x8007042C) At line1: char:1 New-Object -comobject WaAgent.WindowsSetupComponent | % { $_.HandleSetupError() ... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +CategoryInfo : ResourceUnavailable (:) [New-Object], COMException +FullyQualifiedErrorId: NoCOMClassIdentified,Microsoft.PowerShell.Commands.NewObjectCommand I have tried renaming unattended.xml and turning on bootlogging. Neither of those yielded much help. Is there a way I can disable the Azure components that run during OOBE? That seems to be the source of the problem. Mounting the VHD is easy. 0x8007042C looks like a firewall issue, based on my googling. Unfortunately I can't get the machine to boot so I can figure that issue out. Also, I can't get around this problem by booting into safe mode. Thanks for your help, guys.

• Assembling Software RAID in Live CD for data recovery

  - by Maletor

  I need help recovering some data that's on my RAID which is on a LVM on my server running Ubuntu. What happened was I deleted the logical volume that controlled my swap space which was on a partition on drives sda2, sdb2, sdc2, and sdd2 in RAID1. This foobared my whole system for one reason or another. Booting leave me with grub rescue and an error saying that it is an unknown filesystem. When I boot to a live cd I can see my RAID arrays and I can even start them up. However, it doesn't appear to mount them anywhere so I can't see the data. I am in the live cd now and I have done sudo apt-get install mdadm lvm2 so it should be mounting them correctly. I just can't see why it wouldn't. Please any help is appreciated here. Here is some output.

• What is the bash syntax to create a new directory in the directory above?

  - by mozerella

  I aim to make a script for mogrify. The mogrify command will resize images in a directory and put the resized images into a directory on the same directory level, with the same name as the work directory, but with a suffix (_a). The new directory will be moved to another collection later on. Something like this, #!/bin/bash mkdir ../n_a for file in *{.JPG|.jpg}; do mogrify -path ../n_a -resize 1200x1200 -quality 96;done I'm guessing ../ denotes the parent dir when working in a child directory, but I need help here. Edit: "n" needs to be replaced with the syntax for the working directory name. Sorry there was a typo as well third script line, should have read n not x Edit2: This script does exactly what I need and it's silent. #!/bin/bash DEST="../${PWD##*/}_a" mkdir -p $DEST mogrify -path $DEST -resize 1200x1200 -quality 96 *.jpg *.JPG thanks to vgoff for the correct PWD syntax and cesareriva http://www.cesareriva.com/archives/722 for showing me the DEST function. Something else: ${PWD##*/}_a is not caring for spaces in the directory name and the script fails. An empty dir is created in the same dir as the images. Found it out now, it needs quotations on the $DEST too, presumably to help mkdir create the dir with a space in the name, and mogrify to write the files to the right place, like this #!/bin/bash DEST="../${PWD##*/}_a" mkdir -p "$DEST" mogrify -path "$DEST" -resize 1200x1200 -quality 96 *.jpg *.JPG

• auth user and exec a node app only with apache?

  - by Blame

  I couldn't find an answer on the web and I'm trying for days now so I hope that someone with more experience with apache can help me out. Iam writing an web editor and the user should be able to edit a file that is on the server in a directory the user has access to. The problem Iam facing is that I need to authenticate against the system users (shadow/passwd). So the user should be able to login whith a system account and then the node app which does all the logic should be started with the users rights. I hope to get this working without any additional script and only with Apache. I found out two things: I can use mod_auth_pam to authenticate the user There is a mod called suEXEC which can exec the node app with a specified user The problem is that I have to hard code which user is used by suEXEC but I want to decide when the user logs in. Is there any way to authenticate a user against the shadow/passwd and then exec a prog with the users rights? I dont want to run the node app as root and the user should only be able to access his own files. Any help would be appreciated! Thanks, Kodak

• Single application through OpenVPN tunnel (Debian Lenny)

  - by user14124

  I'm using Debian Lenny and I want to tunnel rtorrent only through a OpenVPN tunnel. I have a tunnel running, the config file looks like this: client dev tun proto udp remote openvpn.xxx.com 1194 resolv-retry infinite nobind persist-key persist-tun ca /etc/openvpn/xxx/keys/ca.crt cert /etc/openvpn/xxx/keys/client.crt key /etc/openvpn/xxx/keys/client.key tls-auth /etc/openvpn/xxx/keys/tls.key 1 ns-cert-type server comp-lzo verb 3 auth-user-pass script-security 3 reneg-sec 0 My idea is that I could run a sockd proxy internally that redirects traffic to the openvpn tunnel. I could use the *nix "proxifier" application "tsocks" to make it possible for rtorrent to connect through that proxy (as rtorrent doesn't support proxies). I have trouble configuring sockd as my IP inside the VPN changes every time I connect. This is a config file someone said would help: http://ircpimps.org/sockd.conf As my IP changes at each connect I don't know what to put in that config file. I have no control over the host side config file. Any help wanted. Any other method is very welcome.

• Why won't Google Chrome open Google Docs, and why is it slow with GMail?

  - by Philip

  OSX 10.6 Snow Leopard: Google Chrome works like a charm most of the time. I have many extensions installed, and I've tried disabling/re-enabling them one by one to find a culprit, with no luck. Here are the problems: (1) Chrome is slow to load GMail. I am fairly sure that clearing the cache alleviates this problem. But I can open Safari, type in the URL, and login to GMail in the time it sometimes takes Chrome to open the page. Shouldn't caching help the page load?!? And sometimes even after recent cache clears it still is slow to load..... Thoughts? (2) Chrome won't open Google Docs at all. Safari does. Again, I tried disabling extensions one-by-one, and I allow cookies and even third-party cookies. But I still am told it has a redirect loop. Any help would be much appreciated. Thanks!

• lamp -- edit PHP file but doesn't change web output -- including die()

  - by Reid W

  Server is standard Linux server on Amazon Web Services. Cent OS 5/Apache/PHP 5.3. No APC. It's worked fine for over a year, but now when I edit some but not all PHP files on the server using vi, the changes don't affect the web output. For example, I edit myfile.php and put a die() at the top, but when I load the page in my web browser, instead of the die() I see the content that would show up if the die() weren't there. svn updating the file in question doesn't help either. Files are on an Amazon EBS partition symlinked to /var/www/html. Just to reiterate -- this has worked fine for a long time. Restarting apache didn't help, nor did rebooting the server. What's weird is that it's just some of the files but not all. File ownership/permissions are the same for the "good" and "problem" files. I'm not a Linux newbie but am at a complete loss with this, and couldn't find anything on Google either. Any hints would be much appreciated!

• linux: per-process monitor, every 10 minutes, with history access

  - by Inbar Rose

  I really didn't know a better way to ask my question, hence you get a horribly named question. I will explain what i want to do, maybe that will help you help me. I would like to have my linux machine continuously monitor (every 10 minutes) all the processes on my machine. The information from each process that I require is the name, CPU usage, allocated (virtual) memory, and resident (ram) memory. If these periodic reports were to be looked at, they would look something like this: PROCESS CPU RAM VIRTUAL name1 % MB MB name2 % MB MB ...etc..etc These reports should be stored in such a way that I can access them at a later date by giving a date/time scope (range). For instance, if I want to see the history of my processes from 12:00:00 1.12.12 till 12:00:00 2.12.12 I can - and it should give me the history of the processes for every 10 minutes between those date/time borders. The format of the return is not important, that will be handled by a script anyway and can be modified into anything I need. I have looked into a few things so far, but have not found something that clearly meets my needs. Among the things i searched: sar, free(1), top(1).. and a few other things. It should be a simple issue, i can already see all this information by simply looking at my htop, but i need only a tool that will gather the desired fields for me for each processes every 10 minutes, and then also let me extract slices of that data based on date/time scopes (ranges). note: I have limited experience with linux, so please give detailed information. note2: The desired output will be something like this (after receiving the desired range) CPU USAGE BY PROCESS: proc_nameA 1,2,2,2,2,2...... numbers represent % usage every 10 minutes... proc_nameB 4,3,3,6,1,2...... The same idea with the other information.

• Moving from 1 Linux Partition to Many over USB Mount

  - by Mistiry

  We have devices which use Compact Flash for storage. They work OK, but we recently got industrial-grade CF cards to start using. One of the major problems we get is corruption on the flash card. As it is now, these flash cards run Debian with everything in a single partition. We want to have multiple partitions on the new industrial CF cards to help avoid some of the corruption problems. I booted up the device, and attached a USB CF reader. I then used fdisk to partition the CF card in the USB reader. How can I move the data to these partitions so that it works? I have a partition for each of these directories: /lib /var /root /boot /tmp /home /etc / swap space I imagine I can't just use rsync - do I need to attach a second CF reader with a copy of the CF card, so that it's not active and in-use - and then copy from the first reader to the second? How will the system know where to find its files? I know I'd have to change fstab, but that resides in /etc, which will be on a separate partition...how will it find the fstab file if it can't find /etc? And what about grub? I'm at a loss, perhaps its just because I'm under the weather, or I'm just missing a piece of logic here... Any help is greatly appreciated, this is somewhat urgent as our existing stock is nearing its end and we don't want to purchase anything but these industrial cards, but need to get it working with partitions.
