  • Android SDK emulator freezes on a Mac running OS X 10.6 Snow Leopard

    - by Donald Burr
    I'm having trouble running the Android SDK on both of my Macs running OS X 10.6.2 Snow Leopard. This appears to be a 64 bit vs. 32 bit issue, as Snow Leopard now defaults to 64-bit everything, including the Java virtual machine. I found this webpage with instructions on how to get the Android tools to run in the 32-bit Java VM, and I am now able to run the Android GUI tool to download SDK files, create AVM's, etc. However, when I try the Hello World tutorial and get to the point where I run my application under the Android emulator, everything goes south. The emulator appears to start but it hangs (spinning beachball of death cursor) without displaying anything. (This only hangs the emulator; the rest of the system still works fine.) If I follow the exact same steps (minus the 32-bit java hack) in a Windows virtual machine, everything works fine. Googling didn't yield anything useful (except for the 32-bit java hack I spoke of earlier). This occurs on both my Mac Pro tower and 13" MacBook Pro. Does anyone have any suggestions?

  • Apache2 with SSL and mod_jk on SUSE Linux Enterprise | Apache always starts SSL disabled

    - by Shaakunthala
    I have installed Apache2 (with mod_ssl enabled) on SUSE Linux Enterprise Server 11 (x86_64) (patchlevel 1), using YaST. Once installed, I tested whether everything works fine so far. SSL also worked fine. Just 'apache2ctl start' was enough to make everything working. Then I installed mod_jk and applied the following configuration changes to make it work. /etc/sysconfig/apache2 (added JK module) APACHE_MODULES="... ... ... ... ...jk" /etc/apache2/httpd.conf (included mod_jk.conf) Include /etc/apache2/mod_jk.conf /etc/apache2/mod_jk.conf (new file) JkLogFile /var/log/apache2/mod_jk.log JkWorkersFile /etc/apache2/mod_jk/workers.properties JkShmFile /etc/apache2/mod_jk/mod_jk.shm # Set the jk log level [debug/error/info] JkLogLevel info # Select the timestamp log format JkLogStampFormat "[%a %b %d %H:%M:%S %Y] " mod_jk.log & mod_jk.shm files were also created. /etc/apache2/mod_jk/workers.properties (new file) worker.list=jira worker.jira.type=ajp13 worker.jira.host=127.0.0.1 worker.jira.port=8009 Once everything is done, I've restarted Apache using the following command, apache2ctl restart Then I observed that SSL is not working. When checked with telnet, I observed that port 443 is not open. In listen.conf, if I specify port 443 bypassing 'IfDefine' and 'IfModule' conditions, then SSL works properly. This is likely the 'SSL' flag is not passed to Apache. I did not make this a persistent change as I thought it might not be the correct practice. I checked /etc/sysconfig/apache2 to see if this has been altered, but it is there. Although this flag is enabled, Apache won't start with SSL support. APACHE_SERVER_FLAGS="SSL" Finally, I had to start Apache using the following command, apache2ctl -D SSL -k start And my question is, why did Apache (or apache2ctl) fail to start with SSL when I have installed and correctly configured mod_jk, and no other configuration changes were applied? Have I missed anything? Thanks in advance. -- Shaakunthala

  • Howto make a diff of a bios or backup/ restore all bios settings

    - by sfonck
    Hi, I'm using an Dell M90 Precision Laptop which has a NVidia Quadro FX 2500M graphics card and is running Windows XP. Laptop has been running fine - but a few weeks ago screen went 'white' - restarted computer- bios and startup screens show weird green dots and stripes, normal startup only shows a black screen... only VGA mode works to display something. I've been trying to remove and reinstall the correct drivers downloaded from Dell's website - no solution. I gave up and reinstalled XP - everything was working perfect again. 2 weeks later - again the white screen - tried everything again (flashin new bios also - nothing works) Reinstalled XP - everyhting was working again, so I made a DriveSnapShot of the partition. Today - again the 'white screen'. Ok, no problem ...I was thinking all I needed to do was to restore the DriveSnapShot backup... Few minutes later the backup is restored ... but guess what: video driver does not work correctly... As the DriveSnapShot restored the complete partition, as it was at the time everything was working perfectly, this would mean my driver problems are due to 'settings' in the bios or on the graphics-card itself + these 'settings' can get overridden by doing a new XP-install.... I'm out of options, can somebody help me to find a solution for this problem: Is there some way to backup and restore a bios after seeing some problems? Is there some way to know what is causing this problem like a bios diff utility? Thanks!

  • Backup Gmail using Mail.app and IMAP without redundancy

    - by Cawas
    I don't care for actually using mail app, I use mostly the gmail interface and mail app just for offline, for quickly reading and eventually replying. Everything is working fine, I think I've followed every guide out there... Here's a great one. But I could find nothing about avoiding redundancy. Well, I can manually do that either by using POP or by checking off most of my labels out of IMAP. But I do use a lot of labels and I often label messages with more than 1 label. And I want them on mail app. Is there anyway to make it keep just 1 copy of repeated messages? Maybe there's a message id or checksum that could be used... If there isn't a way to do it, be assured I still prefer having the extra messages and "wasting" space rather than not having any. edit: I've came across many solutions for finding duplicate files, but they just delete the files. That just make things worst: Mail will just sync it all again. I've realized it's probably better to keep two accounts setup, POP for backup and IMAP for everything else with removing the "All Mail" from it. That's because if the "All Mail" on the server is deleted for any reason, my "All Mail" local will also get deleted, while POP will keep all files regardless of the server. This doesn't solve the redundancy issue at all, but it doesn't create any new issue as well, and I can even use the search properly, without duplicated results, if I search just on the POP. So it helps optimizing a little bit. But I still think the best way to solve this issue would be having something such as aamann's Mail Scripts tweaked to hardlinking the duplicates rather than deleting, and optimized to not need to scan everything every time. I'm trying to contact him and see what we can do. At any pace, I'm still looking for an answer!

  • Audio Static/Interference regardless of audio interface?

    - by Tom
    I currently am running a media center/server on a Lubuntu machine. The machine specs: Core 2 Duo Extreme EVGA SLI 680i MotherBoard 2 GB DDR2 Ram 3 Hard Drives no raid - WD Caviar Black, Green, and Samsung Spinpoint Galaxy GTX 220 1GB External USB Creative XI-FI Extreme Card 550W Power Supply This machine is hooked up through an optical cable to an ONKYO HTR340 Receiver through the XIFI card. Whenever I play any audio regardless if it is through XBMC, the default audio player, a flash video, etc, I get a horrible static sound that randomly gets louder. Here is a video of the sound: http://www.youtube.com/watch?v=SqKQkxYRVA4 This static comes in randomly, sometimes going away for short periods, but eventually always comes back. So far I have tried everything I could think of: Reinstalling OS Installing/upgrading/repairing PulseAudio/Alsa Installing alternate OSes, straight Ubuntu, Lubuntu, Xubuntu, Arch, Mint, Windows 7 Switching audio from the external card to internal Optical, audio out through HDMI, audio out through headphones Different ports on receiver (my main desktop sounds fine on the same sound system) Different optical cables Unplugging everything unnecessary from the motherboard (1 HD, 1 Stick of Ram, 1 Keyboard) Swapping out ram Swapping out the motherboard Replacing the Graphics Card (was replaced due to fan being noisy, not specifically for this problem) Different harddrives Swapping power supply Disabling onboard audio Pretty much everything short of swapping the CPU. I haven't been able to narrow down the problem and it is getting frustrating. Is it possible that the CPU is faulty and might cause a problem such as this, or that the PC case is shorting out the motherboard? Any kind of suggestions will be appreciated.

  • DPM 2010 PowerShell Script to Easily Restore Multiple Files

    - by bmccleary
    I’ve got what I thought would be a simple task with Data Protection Manager 2010 that is turning out to be quite frustrating. I have a file server on one server and it is the only server in a protection group. This file server is the repository for a document management application which stores the files according to the data within a SQL database. Sometimes users inadvertently delete files from within our application and we need to restore them. We have all the information needed to restore the files to include the file name, the folder that the file was stored in and the exact date that the file was deleted. It is easy for me to restore the file from within the DPM console since we have a recovery point created every day, I simply go to the day before the delete, browse to the proper folder and restore the file. The problem is that using the DPM console, the cumbersome wizard requires about 20 mouse clicks to restore a single file and it takes 2-4 minutes to get through all the windows. This becomes very irritating when a client needs 100’s of files restored… it takes all day of redundant mouse clicks to restore the files. Therefore, I want to use a PowerShell script (and I’m a novice at PowerShell) to automate this process. I want to be able to create a script that I pass in a file name, a folder, a recovery point date (and a protection group/server name if needed) and simply have the file restored back to its original location with some sort of success/failure notification. I thought it was a simple basic task of a backup solution, but I am having a heck of a time finding the right code. I have seen the sample code at http://social.technet.microsoft.com/wiki/contents/articles/how-to-use-a-windows-powershell-script-to-recover-an-item-in-data-protection-manager.aspx that I have tried to follow, but it doesn’t accomplish what I really want to do (it’s too simplistic) and there are errors in the sample code. Therefore, I would like to get some help writing a script to restore these files. An example of the known values to restore the data are: DPM Server: BACKUP01 Protection Group: Document Repository Data Protected Server: FILER01 File Path: R:\DocumentRepository\ToBackup\ClientName\Repository\2010\07\24\filename.pdf Date Deleted: 8/2/2010 (last recovery point = 8/1/2010) Bonus Points: If you can help me not only create this script, but also show me how to automate by providing a text file with the above information that the PowerShell script loops through, or even better, is able to query our SQL server for the needed data, then I would be more than willing to pay for this development.

  • Can I monitor a service's memory/cpu usage on OpenSolaris?

    - by Phillip Oldham
    What would be the best way to monitor a service's memory/load on the OpenSolaris platform so that one can send alerts and automate service management (restarts, etc) based on "rules"? On the linux platform I use Monit, but since OpenSolaris has SMF I thought there may be a complimentary service "built-in" if SMF doesn't have those features and I'd prefer to use a standard OpenSolaris app if there is one.

  • Opera user script to fill out some form fields

    - by STATUS_ACCESS_DENIED
    I'm looking for a user script that lets me fill out some form fields that are not covered by the Magic Wand in Opera. Alternately I could accept a solution that lets Opera accept other form fields with the Wand. To give you one example: when logging into any of the StackExchange sites, I need to manually enter (or enter from a note) the URL of the OpenID provider. I would like to automate this in particular plus several other sites where a similar situation exists.

  • Selenium server causes crazy load on server - how to prevent?

    - by Eric
    I'm running this linux: Linux host.themepark.com 2.6.32-220.4.1.el6.x86_64 #1 SMP Tue Jan 24 02:13:44 GMT 2012 x86_64 x86_64 x86_64 GNU/Linux And I run the Selenium stand-alone server on my box with this command: java -jar /home/l/cron/selenium-server-standalone-2.24.1.jar > /logs/selenium.log 2>&1 & Here's the problem: as soon as I do that, the server load starts skyrocketing. I even went back and downloaded older versions of the Selenium server, but same results with 2.23.1, 2.23.0, and 2.19.0. Note that the server load starts going nuts before I issue ANY commands to Selenium or do anything else. All I'm doing is firing up the server, per the command above. This used to work perfectly on my server without causing massive server load, so something has changed, but I'm not sure what. My server is a managed VPS so I don't know if there is some kind of auto-update script that kicked in or what... but it's a problem. (Incidentally, even though the server load climbs like crazy, everything still works: after firing up Selenium, my server creates a screen with Xvfb so Firefox will be happy, then a PHP script talks to Selenium to do what it needs to do before shutting everything down. It takes a LONG time, and the load gets all the way up to 8 [!!!] before it is finished, which kills my web server and makes the main site horribly unresponsive... but it does get everything done.) Any suggestions for what is going on, why it's started doing this and/or, most importantly, how I can make Selenium not kill the server when it starts up... would be GREATLY appreciated!

  • running vmstat around a command

    - by svrist
    Im trying to automate a long list of database experiments. I would like to save vmstat output while specific parts of the experiments are running. Does something exist along the lines of time(1) or script(1) that I could use to say: " While this command is running, save vmstat 2(or similar) output to a file " I am aware that vmstat gives my vmstat for the complete system including other processes, but that is OK for my usage. (Running Ubuntu 9.10 if that makes a difference)

  • Migrate installation from one HDD to another?

    - by dougoftheabaci
    I have a server with a 64 GB SSD inside. It runs just fine, but occasionally there's a hiccup that causes it to nearly fill up. When that happens my server starts to lockup and generally misbehave. I'm looking to buy a bigger SSD (either 128 GB or 256 GB) but I'm a bit unsure of how best to make the transition. For a start, I don't have an external monitor. If I need one I'll have to borrow it from work. Most of the time I just SSH into the server from my iMac. The only solution I can think of would be to buy two FW800 2.5" cases, boot from the 64 GB SSD and clone it to the 128 GB SSD. Seem a bit excessive but it might be my best option. I do have more than one SATA port on my server, but they're all currently being use for storage drives. They don't mount by default, so I could unplug them and just have the two SSDs and do the whole thing via SSH. This is another option I'm considering. My main concern with either is how best to make sure everything goes across. I want a carbon copy of the first one onto the second. This is especially important because I have a ZFS volume (my storage) and I'm a bit unfamiliar with how to move everything across. I could just start fresh and reinstall everything on the SSD, but that seems like extra trouble I don't need. So any advice on how best to achieve my goals would be appreciated. Thanks! Server is running Ubuntu Server 12.04. The iMac has 10.8.1.

  • Dell PE2950 - slow IO rates for writing and reading locally

    - by OrenM
    I'm having a serious issue with dell server PE2950. The server has really slow IO rates, so slow that I'm not able to use it anymore I tried few things to solve this: changing disks to new disks (configured them as raid1) changing perc card + perc cables reinstalling the OS of course, had to cause of changing of disks, centos 5.5 x64bit firmware update to everything virtual disks policy: No Read Ahead,Write Back, disk cache policy disabled. openmanage doesn't alert about anything, also i ran dell's diag tests, everything passed, also dell didn't see anything in deset log. dell offered to reseat everything, including the cpu, we did that as well, still io rates are slow I have several PE2950 servers, and I never had such a thing with any of those. All have similar or exact hardware as this one, all configured the same, with the same os centos 5.5 x64, same disks, same raid, same policy. Just for comparison: the problematic PE2950 server: [root@bad ~]# time sh -c "dd if=/dev/zero of=/tmp/ddfile bs=8k count=200000 && sync" 200000+0 records in 200000+0 records out 1638400000 bytes (1.6 GB) copied, 27.7946 seconds, 58.9 MB/s real 0m33.968s user 0m0.531s sys 0m26.000s good PE2950 server (with the exact same hardware): [root@good ~]# time sh -c "dd if=/dev/zero of=/tmp/ddfile bs=8k count=200000 && sync" 200000+0 records in 200000+0 records out 1638400000 bytes (1.6 GB) copied, 3.19999 seconds, 512 MB/s real 0m7.694s user 0m0.053s sys 0m4.057s Hopefully you will have an idea what can cause the problem.

  • Apache+PHP on Windows Server 2008

    - by Álvaro G. Vicario
    I've installed Apache/2.2 and PHP/5.3 lots of times under Windows XP, Windows Vista and Windows Server 2003. The official *.msi installers work fine and configure everything. Now I need to install them into a Windows Server 2008 R2 Standard 64-bit box and I'm facing nothing but problems: There are no official 64 bit binaries for Apache and no binaries at all for PHP (official or third-party). It's alright, I'll do with good 32 bits, but it's kind of surprising. Official documentation is vague, generic and completely unaware of UAC or any recent Windows security feature. The PHP installer is unable to configure mod_php and the Apache installer is unable to configure... well, Apache. After three hours I've finally reached the point where I'm installing everything in the root folder and assigning full control access to all users in all files and directories and all I've got is a PHP-less Apache server that's able to serve static pages. So I guess it's time to stop and think. My question is: Has anyone installed an Apache+PHP production server under Windows Server 2008 in a serious, secure and reliable way and documented the whole process? Or should I just find a bundle like XAMPP and the like that requires no installation? === EDIT === I've installed Xampp Lite 1.7.3 and everything was working in 5 minutes. I'd still like to find some documentation about installing the original packages: XAMPP installs tons of stuff I don't need and offers no tool to enable and disable PHP extensions.

  • Monitor connected with WiDi just shows a black screen

    - by Pops
    I have a Dell XPS 18 and want to use an external monitor with it. The monitor has VGA and DVI-D inputs. The XPS 18 has no video output ports, but it does support Intel WiDi. I have a Netgear P2TV2000 WiDi receiver, but it only has composite and HDMI outputs. I'm connecting the receiver to the monitor with an HDMI cable and an HDMI/DVI-D adapter. So, in short, the video path is: Computer → WiDi → WiDi receiver → HDMI cable → HDMI/DVI-D adapter → Monitor After setting all this up, I can't get anything to display on the monitor. At the moment I power the monitor on, I can see my desktop for a brief fraction of a second, and then everything goes black. All of the relevant drivers have been updated to the latest versions. When I use a different WiDi-enabled computer to connect to the same monitor, everything works fine. When I use the original computer and receiver to connect to a TV, everything works fine. It's only when I connect the original computer to the monitor I want to use that the connection fails. What could be going wrong here, and how can I get the video to work consistently?

  • Execute a remote command on a Mac from Windows

    What's the easiest way to execute a single command on a Mac from a remote Windows machine, via batch? I'd like minimal pre-configuration (like SSH credentials) to exist on either machines, as I need to apply this on several Win/Mac pairs. The macs all have a common user/password (in fact, they are on the same domain), and I want to automate this as painlessly as possible.

  • Ventrilo sound delay issue in Windows 7

    - by TM
    I've upgraded my machine to Windows 7 Professional (x64) (using format + clean install, not upgrade install). Everything seems to work fine except for Ventrilo. I used to have Vista Business x64 and Ventrilo worked fine there, on the same machine. The issue I am having is that when I am playing a game and using Ventrilo, everything works fine at first, but after a few minutes, I stop hearing anything that people say. If I minimize, I can see the speaker icons lighting up (meaning that people are talking), but I still can't hear anything. The sounds from the game and other OS sounds still play through the speakers just fine. Eventually, I will close ventrilo and then after a few seconds I will start hearing things that people were saying several minutes ago. I start hearing everything that was said, with no "silent time" in between. Note that the sounds keep playing even AFTER the ventrilo process is dead. I've tried using Ventrilo x64 and x86 versions. Does anyone have any advice on how to fix this problem?

  • httpd.config Easy Apache WHM CentOS

    - by jessie
    First let me explain how I got to this situation. I run a Streaming Video Site. Videos are about 100-250MB in size at any given time there are 500 people on the site. So I guess that would make then static. Recently My site started getting really slow and the only way to fix it temporarily was to restart apache. Now there was no change in traffic that could have caused this. My site is not being attacked. My hosting company recomended to implement mpm_mod and suPHP. They did that by using Easy Apache in WHMS. Then everything was working fine but a little slow. I researched around and to my understanding that mpm will do that but be more table. I was told that installing FastCGI would speed things up just enough. Well that made everything worse. The site is slow and time's out. I used WHM and took off fastCGI but its still the same, it seems like everything i do as of now nothing changes. I even did a roll back on the htconfig file but that didn't work. I'm not sure how to fix this. and my hosting network guy wont be able to touch the problem until Tuesday. I have root access.

  • Is there an AUTOMATED way to pin items to the taskbar in a windows 2008 TS environment?

    - by l0c0b0x
    We have a Windows 2008 (R2) Terminal Server environment and would like to find a way to automate the addition (Pinning) of programs to the Windows taskbar for our users. My first thought was to do this from a Group Policy, but haven't been able to find a setting for this. I've heard you can 'probably' do it via a script, but haven't seen any examples yet (I'm not a programmer, but have worked with batch scripts before). Please advice. Thanks!

  • Which database to use and system/db administration by layman [closed]

    - by blah
    So my friend and I got briliant ;) idea for a business. Since it is not predictable whether it will work out or not, we decided to keep cost as low as possible to start with, in particular not to hire anyone. If it will work out as expected it will generate enough profit to hire professionals in few months. But for the first few months we'll be doing everything by ourselfs. He's a business/finance major, and I'm a software developer, so obviously I have to take care of IT :) It will be a webapp, written in python/django. My questions regarding this project: 1) What database should I choose? I'm experienced with oracle, and have been working with SQL Server for a while, but both of them are too expensive(at least now). It's a developer experience, I've never done any dba stuff. I'm looking for something free(as in beer). Looks like MySql or PostgreSQL are most popular in this sector. I would appreciate any comments on which db to choose. I'm open to any suggestions(it doesn't have to be MySql or Postgre). Here's what I know about data: It will be almost dates and numbers, a little bit of text. Searched mainly by dates. Data will almost never be updated, mostly inserted and browsed. From 30k to 300k new records/month. 2) Servers. My idea is to rent two dedicated servers. During normal operation one would be a web server(debian/apache), other would be a db server(debian/?). My recovery plan is to install everything on both, and in case of trouble with one of machines just run everything on the other one. Does it even makes sense? Any other tips appreciated. Thanks.
