  • Syntax error in Maya Python Script [on hold]

    - by Enchanter
    Ok this error is immensly frustrating as it is obviously a simple syntax issue. Basically I've written two lines of maya script in python designed to create a list of the names of all the joints of a model currently selected in the model viewer. Here are the two lines of script: import maya.cmds joints = ls(selection = true, type = 'joint') Upon compiling the code the script editor is saying there is a syntax error in the second line, but I do not see any reason why this code should not execute?

  • Threads slowing down application and not working properly

    - by Belgin
    I'm making a software renderer which does per-polygon rasterization using a floating point digital differential analyzer algorithm. My idea was to create two threads for rasterization and have them work like so: one thread draws each even scanline in a polygon and the other thread draws each odd scanline, and they both start working at the same time, but the main application waits for both of them to finish and then pauses them before continuing with other computations. As this is the first time I'm making a threaded application, I'm not sure if the following method for thread synchronization is correct: First of all, I use two global variables to control the two threads, if a global variable is set to 1, that means the thread can start working, otherwise it must not work. This is checked by the thread running an infinite loop and if it detects that the global variable has changed its value, it does its job and then sets the variable back to 0 again. The main program also uses an empty while to check when both variables become 0 after setting them to 1. Second, each thread is assigned a global structure which contains information about the triangle that is about to be rasterized. The structures are filled in by the main program before setting the global variables to 1. My dilemma is that, while this process works under some conditions, it slows down the program considerably, and also it fails to run properly when compiled for Release in Visual Studio, or when compiled with any sort of -O optimization with gcc (i.e. nothing on screen, even SEGFAULTs). The program isn't much faster by default without threads, which you can see for yourself by commenting out the #define THREADS directive, but if I apply optimizations, it becomes much faster (especially with gcc -Ofast -march=native). N.B. It might not compile with gcc because of fscanf_s calls, but you can replace those with the usual fscanf, if you wish to use gcc. Because there is a lot of code, too much for here or pastebin, I created a git repository where you can view it. My questions are: Why does adding these two threads slow down my application? Why doesn't it work when compiling for Release or with optimizations? Can I speed up the application with threads? If so, how? Thanks in advance.

  • Hows to set Skype shortcut for opening existing instance?

    - by Koffeehaus
    I'm using Linux for about two years now, but due to my Windows legacy I like keeping shortcuts on my desktop instead of dockies, panel shortcuts, etc. If Skype is already running, pressing the shortcut starts a new sequence rather than opening an existing one. This is kinda cool as you can have two accounts running. But I only have one. So, my question is whether it is possible to tweak Skype into opening an already existent instance when pressing the shortcut?

  • Ubuntu 11.10 error message at startup after clean install

    - by user999687
    I have just installed Ubuntu 11.10 (did a fresh install and erased 11.04). After the reboot it appeared a log on the screen, saying all the starting services on the left and [OK] on the right. However, two particular entries, starting automatic crash report installation and starting restore sound card(s') mixer state(s) were set on [FAIL]. After that, Ubuntu did not boot. Is there any way that i can skip those two entries and boot Ubuntu?

  • Protobuf design patterns

    - by Monster Truck
    I am evaluating Google Protocol Buffers for a Java based service (but am expecting language agnostic patterns). I have two questions: The first is a broad general question: What patterns are we seeing people use? Said patterns being related to class organization (e.g., messages per .proto file, packaging, and distribution) and message definition (e.g., repeated fields vs. repeated encapsulated fields*) etc. There is very little information of this sort on the Google Protobuf Help pages and public blogs while there is a ton of information for established protocols such as XML. I also have specific questions over the following two different patterns: Represent messages in .proto files, package them as a separate jar, and ship it to target consumers of the service --which is basically the default approach I guess. Do the same but also include hand crafted wrappers (not sub-classes!) around each message that implement a contract supporting at least these two methods (T is the wrapper class, V is the message class (using generics but simplified syntax for brevity): public V toProtobufMessage() { V.Builder builder = V.newBuilder(); for (Item item : getItemList()) { builder.addItem(item); } return builder.setAmountPayable(getAmountPayable()). setShippingAddress(getShippingAddress()). build(); } public static T fromProtobufMessage(V message_) { return new T(message_.getShippingAddress(), message_.getItemList(), message_.getAmountPayable()); } One advantage I see with (2) is that I can hide away the complexities introduced by V.newBuilder().addField().build() and add some meaningful methods such as isOpenForTrade() or isAddressInFreeDeliveryZone() etc. in my wrappers. The second advantage I see with (2) is that my clients deal with immutable objects (something I can enforce in the wrapper class). One disadvantage I see with (2) is that I duplicate code and have to sync up my wrapper classes with .proto files. Does anyone have better techniques or further critiques on any of the two approaches? *By encapsulating a repeated field I mean messages such as this one: message ItemList { repeated item = 1; } message CustomerInvoice { required ShippingAddress address = 1; required ItemList = 2; required double amountPayable = 3; } instead of messages such as this one: message CustomerInvoice { required ShippingAddress address = 1; repeated Item item = 2; required double amountPayable = 3; } I like the latter but am happy to hear arguments against it.

  • big speed difference on a network link with and without VPN tunnel

    - by xirtyllo
    Scenario: We have a network link between two offices. The link is provided by a third party company through a VLAN on their network, but to us it is totally transparent -as if we had a simple ethernet cable going from one location to the other-. We have one router at each side of the link, with 3 VPN tunnels in between the two. The test: When I test the speed of the network link with the routers in place, with one laptop directly connected to the router on each side, I consistently get ~30/35Mbps. But if I take out the routers and I test the link connecting the laptops directly to the ethernet cable at each side, I consistently get ~85/88Mbps. It's quite a big performance hit, and I would tend to think that the VPN tunnels are responsible for the slow down. Is it normal that this configuration (two routers with three VPN tunnels between them) takes away so much bandwidth? More info: The encryption algorithm used for the VPN tunnels is AES128. The routers model is Zyxel USG200 and Zyxel USG1000, and their CPU, memory, and storage use is well within normal limits. The nominal bandwidth of the network link is 100Mbps. The network link in question is supplied by a third party company (the building in between our two offices). Basically it passes through their network as a VLAN, but the VLAN is completely transparent to us (e.g. no configuration required on our side, just like one single cable from end to end). Unfortunately (or maybe fortunately) I cannot directly test different routers configurations as I'm not the person in charge of it.

  • mod_rewrite: redirect from subdomain to main domain

    - by Bald
    I have two domains - domain.com and forum.domain.com that points to the same directory. I'd like redirect all request from forum.domain.com to domain.com (for example: forum.domain.com/foo to domain.com/forum/foo) without changing address in addres bar (hidden redirect). I wrote something like this and put it into .htaccess file: Options +FollowSymlinks RewriteEngine on RewriteCond %{HTTP_HOST} ^forum\.example\.net$ RewriteRule (.*) http://example.com/forum/$1 [L] RewriteCond %{REQUEST_FILENAME} !-s [NC] RewriteCond %{REQUEST_FILENAME} !-d [NC] RewriteRule ^(.+) index.php/$1 [L] That works only if I add Redirect directive: RewriteRule (.*) http://example.com/forum/$1 [R,L] But it changes previous address in address bar. EDIT: Ok, let's make it simple. I added those two lines at the end of the c:\windows\system32\drivers\etc\hosts on my local computer: 127.0.0.3 foo.net 127.0.0.3 forum.foo.net Now, I created two virtual hosts: <VirtualHost foo.net:80> ServerAdmin [email protected] ServerName foo.net DocumentRoot "C:/usr/src/foo" </VirtualHost> <VirtualHost forum.foo.net:80> ServerAdmin [email protected] ServerName forum.foo.net DocumentRoot "C:/usr/src/foo" </VirtualHost> ..and directory called "foo", where i put two files: .htaccess and index.php. Index.php: <?php echo $_SERVER['PATH_INFO']; ?> .htaccess: Options +FollowSymlinks RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} ^forum\.foo\.net$ RewriteCond %{REQUEST_URI} !^/forum/ RewriteCond %{REQUEST_FILENAME} !-s [NC] RewriteCond %{REQUEST_FILENAME} !-d [NC] RewriteRule ^(.+)$ /index.php/forum/$1 [L] RewriteCond %{HTTP_HOST} !^forum\.foo\.net$ RewriteCond %{REQUEST_FILENAME} !-s [NC] RewriteCond %{REQUEST_FILENAME} !-d [NC] RewriteRule ^(.+) index.php/$1 [L] When I type address http://forum.foo.net/test in address bar, it displays /forum/test which is good. http://foo.net/a/b/c shows /a/b/c which is good. But! http://forum.foo.net/ displays empty value (should display /forum).

  • How to deal with DELL support system?

    - by Nishant Kumar
    We have purchased a Dell Optiplex 9010 SSFV for our organization's work. Since the first installation two of the USB keyboard keys were not working properly. I had to press those keys two times simultaneously, on first time keys did not work and for for second time it printed two characters (as it were buffering first character.) Two keys that were not working properly: Hexangrave (Below the ESC key: `) Double Quotes (Left the enter key ") We registered our complaint with DELL and they suggested (with some hard to understand and weird ENGLISH accent) some test and tricks, such as switching to different ports, checking keyboard on different PC, and it worked well with diff. PC(with Windows 7 Home Premium installed). It was clear that it is an OS fault, hence they suggested to re-install OS. Problem began here, we have a project on the run and currently a video editing project setup on our system, so can't re-install system in hurry and also DELL persons were not providing any other solution such as updating keyboard driver, etc. Arguments I am a Software Engg. and don't think it is a feasible solution to re-install entire system for simple problems. This prob is coming since the fresh system installation, so I don't think it will solve the problem. Finally, I had to find solution myself and got it here, now I want to show my disappointment to dell persons or at least tell them that they should improve there support system to not advice to re-install entire system for that simple problems. Notes We have purchased 5 years NEXT business day support from DELL for around 8000 INR (Not for that kind of solutions from DELL). It is Dell India Support System. So can anyone tell me how to tackle dell support system officially, so that they will pay more attention in near future. Thanks

  • Bind9 zone files

    - by user42780
    Well for the better part of the last two hours I've tried to figure out what is actually wrong, but I can't seem to find anything obvious to me. What I'm trying to do is setup my DNS for say(per example) domain.com. This should include two NS records, namely ns1.domain.com and ns2.domain.com. With that there should be a mail record, as well as a CNAME record for www. I've been trough roughly 20 how to's in the last two hours, rewrote everything from scratch four times and I still can't seem to find whats wrong. My only suspicion to this might be two things; the error I get from the bind9 daemon when I stop the service, and the named.conf file. The error I get from the bind9 daemon when stopping the service is: * Stopping domain name service... bind9 rndc: connection to remote host closed This may indicate that * the remote server is using an older version of the command protocol, * this host is not authorized to connect, * the clocks are not syncronized, or * the key is invalid. I honestly doesn't know what this means, apart from the key defined in /etc/bind/rndc.key that's not in the named.conf file(yes, I did try to add it to no avail). Here's all the zone files, and configuration files; http://208.77.101.5/bind9/ If anyone could help, it would be greatly appreciated.

  • Linux error when resume from RAM

    - by TuxPotato
    The last two times that I have resumed my laptop from sleep, it has hung and given me this set of errors: [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 1sec aborting [drm:atom_execute_table_locked] *ERROR* atombios stuck executing E692 (len 460, WS 0, PS 4) @0xE6D3 hda_intel: azx_get_responce timeout, switching to single_cmd mode: last cmd=0x01170700 ata6: softreset failed (device not ready) ata4: softreset failed (device not ready) [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 1sec aborting [drm:atom_execute_table_locked] *ERROR* atombios stuck executing E692 (len 460, WS 0, PS 4) @0xE6D3 The last two messages repeat two more times. The first time this happened, Linux's Magic SysRq worked and did a soft reboot, and after that everything was fine till it went to sleep again. It wakes up and gives me this. Here are the laptop stats: Toshiba Satellite L455D-S5976 AMD Sempron SI-42 Processor 2GB DDR2 RAM HD TruBrite Display ATI Radeon Graphics (integrated) Running Ubuntu 10.10 32 bit I'm not sure about the hard drive, but its a 250GB drive with one NTFS partition, two Hidden NTFS, one Linux Swap, and one Ext4. Can someone tell me whats wrong with my laptop? NOTE: This only happens when I close the screen. My computer doesn't go to sleep with the screen open.

  • Whats the difference between local and remote addresses in 2008 firewall address

    - by Ian
    In the firewall advanced security manager/Inbound rules/rule property/scope tab you have two sections to specify local ip addresses and remote ip addresses. What makes an address qualify as a local or remote address and what difference does it make? This question is pretty obvious with a normal setup, but now that I'm setting up a remote virtualized server I'm not quite sure. What I've got is a physical host with two interfaces. The physical host uses interface 1 with a public IP. The virtualized machine is connected interface 2 with a public ip. I have a virtual subnet between the two - 192.168.123.0 When editing the firewall rule, if I place 192.168.123.0/24 in the local ip address area or remote ip address area what does windows do differently? Does it do anything differently? The reason I ask this is that I'm having problems getting the domain communication working between the two with the firewall active. I have plenty of experience with firewalls so I know what I want to do, but the logic of what is going on here escapes me and these rules are tedious to have to edit one by one. Ian

  • ZFS: Mirror vs. RAID-Z

    - by John Clayton
    I'm planning on building a file server using OpenSolaris and ZFS that will provide two primary services - be an iSCSI target for XenServer virtual machines & be a general home file server. The hardware I'm looking at includes 2x 4-port SATA controllers, 2x small boot drives (one on each controller), and 4x big drives for storage. This allows one free port per controller for upgrading the array down the road. Where I'm a little confused is how to setup the storage drives. For performance, mirroring appears to be king. I'm having a hard time seeing what the benefit would be of using RAIDZ over mirroring would be. With this setup I can see two options - two mirrored pools in one stripe, or RAIDZ2. Both should protect against 2 drive failures, and/or one controller failure...the only benefit of RAIDZ2 would be that any 2 drives could fail. The storage should be 50% of capacity in both cases, but the first should have much better performance, right? The other thing I'm trying to wrap my mind around is the benefit of mirrored arrays with more than two devices. For data integrity what, if any, would be the benefit of a RAIDZ over a three-way mirror? Since ZFS maintains file integrity what does RAIDZ bring to the table...doesn't ZFS's integrity checks negate the value of RAIDZ's parity?

  • How to multiseat with HW 3d accel on CentOS 6.3 Final?

    - by user35070
    I would like to setup a multiseat configuration on CentOS 6.3 (two video cards, two keyboards, two mice, two monitors) and have hardware accelerated 3D on both monitors. 3D HW acceleration rules out Xephyr. I saw somewhere that recent versions of GDM (3.3 and newer?) don't support multiseat, so do I have to install KDM to make this work? If I just create a duplicate section with new device identifiers in my xorg.conf file, will this 'just work'? Using different ports on the same video card and separate keyboards, mice, and displays, the result was a desktop which spanned both monitors with both keyboards and mice acting as the same input in the GUI. I will power down and put in the new video card and report on the results soon. Both video cards are nvidia. UPDATE after putting in another NVIDIA video card, default behavior (before changing xorg.conf) is that one screen works normally, and both mice and keyboards are connected to it. Changing xorg.conf and the display manager to KDM and following the directions here https://help.ubuntu.com/community/MultiseatX#Ubuntu_10.04_.28Lucid.29 , I have 2 mirrored screens connected to separate video cards, DRI enabled, and 2 mice both connected to the same pointer. Keyboards don't do anything, however, I probably just need to fix a setting in xorg.conf I would still like to get multiseat functionality, eg. separate screens with separate input devices I have verified that the separate X processes are running (see page above) using 'ps aux | grepX [01]'

  • Intermittent "Lost connection to MySQL server at 'reading initial communication packet'"

    - by db2
    Our web environment consists of two servers. Web front-end. Dell PowerEdge R610, RHEL 5.5, Apache 2.2.17, php 5.2.14. Database server. Dell PowerEdge R710, Windows 2008 R2 Standard x64, MySQL 5.5.11-log x64. Normally these two work perfectly fine together. However, when I try to get them talking via a dedicated LAN on their secondary NICs (each machine has four of them), things get flaky. I have NIC #2 on both machines configured on the 172.16.1.0/24 subnet, with no gateway or DNS servers (obviously, since it's just those two systems), and I put the private IP address of each machine into the hosts file of the other. The routing tables on both machines look okay after I do this. I've tried this with both a crossover cable draped directly between the two NICs, and also via a dedicated vlan on the switch in the rack. In either case, I get intermittent connection problems. It's a fairly small percentage of connections that fail, but it's enough to cause a significant problem, and I have to switch back to the main network connection, which will contend with all the other traffic and hosts on the switch. The full error message that appears in the application log: SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading initial communication packet', system error: 110 Am I doing something really dumb that's causing this to not work properly? Anything I can check in MySQL that would explain why it's failing to connect occasionally?

  • Failed to bring up eth1 in a dual ips solution in ubuntu

    - by lxyu
    I'm using ubuntu 12.04. I tried to assign two ips to two ethernet cards in my server. The content of /etc/network/interfaces is like this: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 114.80.156.a netmask 255.255.255.224 gateway 114.80.156.b auto eth1 iface eth1 inet static address 114.80.156.c netmask 255.255.255.240 gateway 114.80.156.d a b c d have different values, which means the two ips are in different vlans. But I can only bring up eth0 with this command: $ /etc/init.d/networking restart RTNETLINK answers: File exists Failed to bring up eth1. ...done. I have checked the question here which shows the same problem like the one I encountered: Can only bring up one of two interfaces But it seems it's not really solved. And in my situation, I need the 2 ips to use 2 different gateways. So how to fix this problem? Edit1, changed the example config ip from 192.168.0.0/16 subnet to another 'real' subnet. Edit2, the purpose of doing this is fairly simple. Because the ip range I previous in don't have more room for new servers, and I have to move to another ip range. So I want to make the public servers bind to 2 ips for the transition period. I only have really limited knowledge about routing and subnet. @BillThor @rackandboneman, would you please give me some keywords or links on how to setup route for 2 ips? and @Mike Pennington, how do you know I speak chinese?

  • CheckPoint/Amazon VPC VPN tunnel working inconsistently

    - by Lee
    First time poster, so please be gentle and correct me if there's Server Fault etiquette I'm missing. We have two CheckPoint edge devices at sites A & B, independently managed, connecting to two Amazon private clouds. In both cases, the two Amazon VPCs are in the same community on the CheckPoint device. A VPN tunnel exists between the two CheckPoint devices as well. Between Sites A & B and the Amazon VPC in Northern Virigina, we are unable to keep more than one tunnel up. Both will come up, but tunnel 2 will drop an hour after initiation and will not come back up while tunnel 1 is up. We believe the 1-hour period is due to IPsec phase 2 renegotiation, but can't be sure. On our side, we see the tunnel 2 remote endpoint as not responding to phase 2 negotiation. Between Sites A & B and the Amazon VPC in Oregon, we have no issues. Both tunnels are up and fail over properly. The CheckPoint gateways are using domain-based VPNs. According to CheckPoint's advice to Amazon, this won't work. Yet, in Oregon, it does. We've pursued this with Amazon and, despite the fact it's working in Oregon, they've refused to troubleshoot with us further. Can anyone suggest anything we can do to try to get this stabilized? Going to route-based VPNs is not an option for us.
