How to edit screen grabbed video on Windows XP?

- by tangens

Problem I've used CamStudio to record a presentation (fullscreen, 1280x1024, 45 min, no audio) to a small number of AVI files (10 files with about 800 MB total). Now I want to remove the initial and trailer sequences where you see start and stop of CamStudio. I'd like to remove some pauses during the video, too. Question Could you recommend some programs for Windows XP that I can use for this task? The result should be a (small - at least not bigger than the original) video format that I can play back. I've no need to create a DVD etc. Already tried I already tried MAGIX Video Deluxe 16 (Trial Version), but it takes about 2 hours to just export 10 minutes of the video and produces about 2 GB of data for this.

Some Mac applications crash frequently, with "__THE_SYSTEM_HAS_NO_PORT_SETS_AVAILABLE__" in backtrace

- by smokris

Recently I'm finding that some Mac OS X applications are crashing frequently with backtraces like the following: Process: Mail [39226] Path: /Applications/Mail.app/Contents/MacOS/Mail Identifier: com.apple.mail Version: 4.4 (1082) Build Info: Mail-10820000~1 Code Type: X86-64 (Native) Parent Process: launchd [338] Date/Time: 2011-01-12 21:59:48.383 -0500 OS Version: Mac OS X 10.6.6 (10J567) Report Version: 6 Exception Type: EXC_BREAKPOINT (SIGTRAP) Exception Codes: 0x0000000000000002, 0x0000000000000000 Crashed Thread: 12 Dispatch queue: com.apple.root.default-priority [...] Thread 12 Crashed: Dispatch queue: com.apple.root.default-priority 0 com.apple.CoreFoundation 0x00007fff81653975 __THE_SYSTEM_HAS_NO_PORT_SETS_AVAILABLE__ + 5 1 com.apple.CoreFoundation 0x00007fff815a1f69 __CFRunLoopFindMode + 553 2 com.apple.CoreFoundation 0x00007fff815a1c5d __CFRunLoopCreate + 317 3 com.apple.CoreFoundation 0x00007fff815a1a78 _CFRunLoopGet0 + 744 4 com.apple.CoreFoundation 0x00007fff815dc90a CFRunLoopRunInMode + 58 5 com.apple.MessageFramework 0x00007fff81d01183 +[NSRunLoop(MessageExtensions) _flushQueuedEventsAddingSource:] + 120 6 com.apple.MessageFramework 0x00007fff81d010d2 +[NSRunLoop(MessageExtensions) flushQueuedEvents] + 36 7 com.apple.MessageFramework 0x00007fff81ce6515 -[_MFInvocationOperation main] + 275 8 com.apple.Foundation 0x00007fff83921de4 -[__NSOperationInternal start] + 681 9 com.apple.Foundation 0x00007fff83a00beb __doStart2 + 97 10 libSystem.B.dylib 0x00007fff801402c4 _dispatch_call_block_and_release + 15 11 libSystem.B.dylib 0x00007fff8011e831 _dispatch_worker_thread2 + 239 12 libSystem.B.dylib 0x00007fff8011e168 _pthread_wqthread + 353 13 libSystem.B.dylib 0x00007fff8011e005 start_wqthread + 13 [...] Any ideas about what might be causing this and/or how to remedy it?

What 64bit Desktop Linux (gui) Distribution can I run on an intel processor, especially in virtualbox on mac os x?

- by cwd

What 64bit Desktop Linux (GUI) Distribution can I run on an intel processor, especially in VirtualBox on Mac OS X? Ubuntu 32bit works well. ubuntu 64bit is for amd64 only, I think. I know Mac OS X is 64 bit Linux. This is not what I'm asking about. It would be lovely if you could recommend a small install, or one that has a live cd version. Update: I tried downloading the ubuntu-10.10-desktop-amd64.iso package and this is what i get:

Best SQL Server Configuration with this hardware.

- by DavidStein

I just received my new SQL Server from Dell. The server will be serve approximately 15 OLTP databases which average 10GB in size. Here are the basic specs: Dell PowerEdge R510 with up to 12 Hot Swap HDDs,LED Intel Xeon E5649 2.53GHz, 12M Cache, 5.86 GT/s QPI, 6 core (Quantity of 2) 48GB Memory (6x8GB), 1333MHz Dual Ranked RDIMMs for 2 Processors, Optimized PERC H700 Integrated RAID Controller, 1GB NV Cache 300GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 4) 600GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 6) My first thought was to use 3 arrays. OS - Raid 1 - (2)300GB T-Log - Raid 1 (2)300GB DB - Raid 5 (5) 600GB Backup - (1) 600GB - non-raided. However, I could also do the following after purchasing one more drive for backup. OS and T-Log - Raid 10 - (4)300GB DB - Raid 10 (6)600GB The hard drive space is not an issue as the databases are not that large. I'm just trying to optimize the speed of the applications using these databases. So, what would you guys recommend?

How to play an MKV 3D side-by-side video?

- by djechelon

I have a video in Matroska format (MKV, file extension .mkv), 3D half-SBS, where the 1280x720 frame shows the left-eye frame on the left and the right-eye frame on the right. I don't have a 3DTV, but I have NVidia 3D Vision: I tried to open it with PowerDVD 10 with no result (program hangs). With the same PowerDVD, I tried to play the Avatar 3D trailer downloaded from YouTube (MP4 format), but it now shows it the two frames. PowerDVD 10 is advertised to support 3D and 3D Vision. Why can't I play these videos? NVidia Stereoscopic player plays the Avatar trailer fine, but it doesn't support MKV.

Weird DNS bug - external server resolves to internal IP

- by emilecantin

I have a server that is hosted by my university. I have root access, but no control over network setup, firewall, etc. This server's DNS resolves to an internal IP here on campus (10.x.x.x), and an external IP outside campus. I also have a few servers hosted at Amazon, and they mostly work well. However, one of them started to resolve the university server by its internal IP address. This causes problems, as 10.x.x.x on Amazon EC2 is someone else. I have connected to the Amazon server with SSH agent forwarding a few times in the past, to access a Git repository on the university server. Any idea what could cause this?

The previous system shutdown at xxxx was unexpected

For the past two nights we had a remote server shutdown unexpectedly. When rebooted we get the following message: Event Type: Error Event Source: EventLog Event Category: None Event ID: 6008 Date: 16/02/2011 Time: 09:10:43 User: N/A Computer: WELPLAN-1 Description: The previous system shutdown at 07:27:32 on 16/02/2011 was unexpected.

Windows Server 2008 R2 and OSX 10.5/.6/.7, Search, Spotlight

- by Keith Loughnane

I'm handling a migration from a on old mac server to a Windows Server 2008 R2 machine running a 12TB(10 usable) RAID5 server. It's using an SMB share and now the OSX 10.5/.6 users can search sometimes it works but takes up to 10 minutes. The OSX 10.7 machine seems to be fine. I've looked in the root of the shared drive for a .Spotlight-V100 file (ls -a) but it doesn't seem to be there. mdutil says indexing is on for that volume and I have cleared the index using mdutil -E /Volumes/MeSharedVolume numerous times. Any ideas?

Port Forwarding a Specific Port (e.g. 22)

- by Jerry Blair

I'm still confused about establishing an SSH connection (port 22) between two computers on different internal networks. For example: I am on my computer with internal IP address IIP-1, connected to my router RT-1. There are 10 IIPs connected to RT-1. I want to establish an SSH connection to IIP-3 which is connected to router RT-2. There are 10 IIPs connected to RT-2. At any time, there can be multiple SSH connections between IIPs on RT-1 and RT-2. Since I only have port 22 available, I don't know which SSH session is talking between which IIPs. I looked at a couple of similar questions but am still unclear on the solution. Thanks much, Jerry

Force an LXC container to use its own IP address

Sorry if this question has already been asked. I could not find it, I have this setup : +---------------------------------------------------------------------------------------------+ |HOST | | | | +-------------------------------------------------+ | | | UBUNTU-VM | | | | | | | | +-------------------+ | | | | |UBUNTU-LXC | | +------------------+ | | | | 10.0.0.3/24 | 10.0.0.1/24 | |OTHER VM | | | | | eth0-----lxcbr0----------eth0-----------br0----------eth0 | | | | | | 192.168.100.2/24| 192.168.100.1/24 |192.168.100.3/24 | | | | +-------------------+ | +------------------+ | | +-------------------------------------------------+ | +---------------------------------------------------------------------------------------------+ When I ping 192.168.100.3 from my UBUNTU-LXC, the source IP address is automatically changed to 192.168.100.2 by UBUNTU-VM. It's like having a NAT, whereas I really want my UBUNTU-LXC to talk with it own IP address. Is there any way to do this ? Edit : these info may be relevant : I am using KVM +libvirt to set up my VMs Here is how I create my interface in UBUNTU-VM : <interface type='bridge'> <mac address='52:54:00:cb:aa:74'/> <source bridge='br0'/> <model type='e1000'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> </interface>

xauth error with ssh X Forwarding

- by bdk

From my (Debain) Desktop machine, I am trying to ssh into a Debian Server with ssh -X remote-ip After logging into the remote host, I get: /usr/bin/X11/xauth: creating new authority file /root/.Xauthority /usr/bin/X11/xauth: (stdin):1: bad display name "unix:10.0" in "remove" command /usr/bin/X11/xauth: (stdin):2: bad display name "unix:10.0" in "add" command And the X Forwarding doesn't work. From my Desktop I can ssh -X into other Debian servers and it works fine. I found a lot of threads discussing similar issues on google, but they all seem to fade out without a solution, and the simple things suggested there like exporting DISPLAY or setting xhost + don't seem to make a difference.

ODSI + weblogic = JDBC problem

I'm currently developing a web service using ODSI through Oracle Workshop for WebLogic (ex AquaLogic). I created a datasource on weblogic using the driver "Oracle thin driver 10g", the test succeed on WebLogic. (My Database is Oracle 10 10.2.0.1.0) The problem occours when I try to create the Phisical Data Service in the Oracle Workshop. I choose the following options: Data source type = Relational Data source = [THE CORRECT NAME OF THE SOURCE SET ON WEBLOGIC] Database type = ??? Aqualogic, doesn't allow me to select the database type. I guess is a problem related to the driver set on weblogic... but I ain't sure.Does someone know the nature of my problem ? Tnx

When I create a system DSN, my driver choices are SQL server (sqlsrv32.dll 4-10-09), which gives a generic wizard, and SQL Server Native Client 10.0 (sqlncli10.dll 7-10-08), which gives the SQL Server 2008 wizard. I choose the latter. I enter name, description, and have tried both MyPCName and 127.0.0.1 for the server name (browsing turns up nothing). After clicking Next, I leave it at Integrated Windows authentication, and leave Connect to server for additional options checked. After clicking Next, I get the error above. I know it's probably a simple answer, (permission issue?) and I'm a SQL noob, so I appreciate anything that would point me in the right direction. Thanks!

DVD ROM is not working

- by Cyril N.

(note: I don't know in which StackExchange site to put this question, I'll thank the moderator that will move it to a more appropriate place, if there is a S.E. available for my question). I have a DVD RW drive that is well listed in the bios, and if no CD is in, it is also present in the "My Computer" of my Fedora 16. But when I put a disc on it, the icon disapear from "My Computer", and I can not do anything with this ! (Like erasing a RW disc). I'd like to boot a Fedora 17 Live CD image. I burned it on an other computer but when I try to run it in bios, nothing is done and I'm redirected to Grub of my HD. The command cdrecord -scanbus shows this : wodim: Warning: controller returns wrong size for CD capabilities page. wodim: Cannot get CD capabilities data. 6,1,0 601) 'HD-DT%ST' 'DVD%RAM G@22NP20' '1&04' Removable CD-ROM And when I try to mount manually the disc, I got this error : mount: block device /dev/sr0 is write-protected, mounting read-only mount: /dev/sr0: can't read superblock Here's a paste of dmesg | grep sr0 : [ 5.161265] sr0: scsi-1 drive [ 5.161621] sr 6:0:1:0: Attached scsi CD-ROM sr0 [ 834.545978] sr0: Hmm, seems the drive doesn't support multisession CD's [ 841.731194] sr0: CDROM (ioctl) error, command: Get configuration 46 00 00 00 00 00 00 00 20 00 [ 842.021640] sr 6:0:1:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 842.021652] sr 6:0:1:0: [sr0] Sense Key : Aborted Command [current] [ 842.021662] sr 6:0:1:0: [sr0] Add.

How to add PTR record for a /16 IP block in BIND using $GENERATE directive?

- by yegle

I'm trying to reverse map a block of IP using PTR record to some special name so their usage can be easily reflected by a simple nslookup. For example, here's a nslookup result: # nslookup 172.17.201.101 Server: 10.253.33.1 Address: 10.253.33.1#53 101.201.17.172.in-addr.arpa name = for.internal.use.only. And I learned that I can add PTR record for a /24 block by using $GENERATE directive $GENERATE 0-254 $.201.17.172 PTR for.internal.use.only. So here's the question: Am I doing right exposing infomation of IP address by adding PTR record? Any better idea? If the question above is YES, then how to add PTR record for a /16 IP range? I know I can write 255 lines of $GENTERATE directive but any better solution?

Latency issues over internet

- by Stevo

I have a Media Temple server running http://www.popsapp.com which I am having latency issues with. If I run ab -n 100 -c 10 http://www.popsapp.com/ from my local machine I get very bad stats e.g.: Connection Times (ms) min mean[+/-sd] median max Connect: 179 3375 2185.4 2837 12525 Processing: 0 505 693.3 229 4564 Waiting: 0 50 115.4 0 415 Total: 964 3880 2094.5 3159 12608 Whereas if I run it from a rackspace server I have I get this: Connection Times (ms) min mean[+/-sd] median max Connect: 75 76 3.3 75 84 Processing: 235 339 81.4 315 579 Waiting: 159 249 61.7 234 411 Total: 311 415 82.0 390 663 To me this looks like intermediate network issues, but I wouldn't have thought it could be this bad!

How to consolidate servers with the not-very-strong infrastructure

- by Sim

All, Situation We are in retail industry with about 10 distributors and use Solomon as the standard ERP for all our systems Each distributor has 1 HQ and 5 - 10 branches, each branch has their own server (Windows 2000/XP/2003 + Solomon + another built-in POS system) Everyday, branches has to extract data and send (via email/Skype) to HQ for data consolidation purpose When we first deployed our ERP, the infrastructure (e.g. Internet connection) wasn't reliable enough. That's why we went with the de-centralized model (each branch got their own server) Now, the infrastructure is mature already. And we need to consolidate data more quickly (not from branches -- HQ -- our company but something like HQ -- our company only) Goal We just have Solomon servers in distributor HQ. All the transactions in branches (retrieved from POS) will by synchronized with HQ server directly) There is a backup plan just in case the Internet goes down, or HQ server goes down Question With the above question, could you guys suggests some model for me ? Should we use Terminal services, any other solutions ? Any watchout/suggestions ? Any good article to read 'bout this ? Thanks a lot

Deleting large no of files on linux eats up CPU

- by Sanjay

I generate more than 50GB of cache files on my RHEL server (and typical file size is 200kb so no of files is huge). When I try to delete these files it takes 8-10 hours. However, the bigger issue is that the system load goes to critical for these 8-10 hours. Is there anyway where I can keep the system load under control during the deletion. I tried using nice -n19 rm -rf * but that doesn't help in system load. P.S. I asked the same question on superuser.com but didn't get a good enough answer so trying here.

The ping response time doesn't reflect the real network response time

- by yangchenyun

I encountered a weird problem that the response time returned by ping is almost fixed at 98ms. Either I ping the gateway, or I ping a local host or a internet host. The response time is always around 98ms although the actual delay is obvious. However, the reverse ping (from a local machine to this host) works properly. The following is my route table and the result: route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.1.1 0.0.0.0 UG 100 0 0 eth1 60.194.136.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth1 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 # ping the gateway ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_req=1 ttl=64 time=98.7 ms 64 bytes from 192.168.1.1: icmp_req=2 ttl=64 time=97.0 ms 64 bytes from 192.168.1.1: icmp_req=3 ttl=64 time=96.0 ms 64 bytes from 192.168.1.1: icmp_req=4 ttl=64 time=94.9 ms 64 bytes from 192.168.1.1: icmp_req=5 ttl=64 time=94.0 ms ^C --- 192.168.1.1 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4004ms rtt min/avg/max/mdev = 94.030/96.149/98.744/1.673 ms #ping a local machine ping 192.168.1.88 PING 192.168.1.88 (192.168.1.88) 56(84) bytes of data. 64 bytes from 192.168.1.88: icmp_req=1 ttl=64 time=98.7 ms 64 bytes from 192.168.1.88: icmp_req=2 ttl=64 time=96.9 ms 64 bytes from 192.168.1.88: icmp_req=3 ttl=64 time=96.0 ms 64 bytes from 192.168.1.88: icmp_req=4 ttl=64 time=95.0 ms ^C --- 192.168.1.88 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 95.003/96.696/98.786/1.428 ms #ping a internet host ping google.com PING google.com (74.125.128.139) 56(84) bytes of data. 64 bytes from hg-in-f139.1e100.net (74.125.128.139): icmp_req=1 ttl=42 time=99.8 ms 64 bytes from hg-in-f139.1e100.net (74.125.128.139): icmp_req=2 ttl=42 time=99.9 ms 64 bytes from hg-in-f139.1e100.net (74.125.128.139): icmp_req=3 ttl=42 time=99.9 ms 64 bytes from hg-in-f139.1e100.net (74.125.128.139): icmp_req=4 ttl=42 time=99.9 ms ^C64 bytes from hg-in-f139.1e100.net (74.125.128.139): icmp_req=5 ttl=42 time=99.9 ms --- google.com ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 32799ms rtt min/avg/max/mdev = 99.862/99.925/99.944/0.284 ms I am running iperf to test the bandwidth, the rate is quite low for a LAN connection. iperf -c 192.168.1.87 -t 50 -i 10 -f M ------------------------------------------------------------ Client connecting to 192.168.1.87, TCP port 5001 TCP window size: 0.06 MByte (default) ------------------------------------------------------------ [ 4] local 192.168.1.139 port 54697 connected with 192.168.1.87 port 5001 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.0 sec 6.12 MBytes 0.61 MBytes/sec [ 4] 10.0-20.0 sec 6.38 MBytes 0.64 MBytes/sec [ 4] 20.0-30.0 sec 6.38 MBytes 0.64 MBytes/sec [ 4] 30.0-40.0 sec 6.25 MBytes 0.62 MBytes/sec [ 4] 40.0-50.0 sec 6.38 MBytes 0.64 MBytes/sec [ 4] 0.0-50.1 sec 31.6 MBytes 0.63 MBytes/sec

Crossover cable in addition to normal network connection on servers?

- by Zero0ne

I have 2 servers, both with Windows 2003 R2 Each have 2 NIC ports that are 10/100/1000 They are both connected to our LAN + joined to the domain (1 NIC port free on each server) The problem is that our main router is only 10/100 on the ports that these servers are connected to. Since one server is going to host SQL 2005 and the other will be running Altiris NS7, I was hoping that I could use a crossover cable to connect the two directly, thus taking advantage of their 1gbps NIC cards. Is this possible? If so what steps do I need to take to accomplish this? What needs to be done to make sure that when the app server is communicating with the SQL server that it is using the direct link vs traversing the LAN? Thanks a lot!

Could a too low voltage during long periods damage my computer fan?

- by Sopalajo de Arrierez

Computer fans use to run at 12Volt, but most as for today they allow 9Volt or even less to slow down the fan speed (RPM, Revolutions Per Minute). In cases of too low voltage, the fan stops, but I can see it "trying to start again". For example: my Tacens 9dB fan stops at about 10 Volts, but to start it again, 10.5Volt is not enough, and the engine tries to move the fan (I can see a small movement as an "attempt" to move) each 1-5 seconds, but it does not succees, so the fan keeps at 0 RPM. Maybe that "attempt" to move could damage the internal engine of the fan when it last for hours or days?
