  • LTS 12.04.1 will not resolve domain.local websites

    - by user108502
    I have done a brand new installation of the Ubuntu server (v12.10) with bind configured to have a dns zone of gdos.local and apache configured for said domain. With a brand new installation of Ubuntu desktop LTS I try to connect to www.gdos.local and all I get is: Server not found Firefox can't find the server at www.gdos.local. Check the address for typing errors such as ww.example.com instead of www.example.com However if I change the domain to gdos.tmp and type in www.gdos.tmp, I get the internal website. If I change it to mybusiness.local , I get the same error message. If I use a Microsoft os, this works fine, all three domains resolve to a webpage. I have searched the internet flat for the past week on dns issues but have not come up with a solution. I have followed instructions from removing dnsmasq to editing like resolv.conf (in some very strange places) and I still have no joy on getting the .local domain extension to work. I can safely say the issue is not with the server but with the desktops because if the issue was server related the Microsoft OS's would not resolve it either. I have done several installs of the desktop in an effort to make sure that I did not break anything while trying to fix this. Please can anyone point to a workable solution for fixing the .local domain extension. Thank you Mark Hollander

  • Prevent oversteering catastrophe in racing games

    - by jdm
    When playing GTA III on Android I noticed something that has been annoying me in almost every racing game I've played (maybe except Mario Kart): Driving straight ahead is easy, but curves are really hard. When I switch lanes or pass somebody, the car starts swiveling back and forth, and any attempt to correct it makes it only worse. The only thing I can do is to hit the brakes. I think this is some kind of oversteering. What makes it so irritating is that it never happens to me in real life (thank god :-)), so 90% of the games with vehicles inside feel unreal to me (despite probably having really good physics engines). I've talked to a couple of people about this, and it seems either you 'get' racing games, or you don't. With a lot of practice, I did manage to get semi-good at some games (e.g. from the Need for Speed series), by driving very cautiously, braking a lot (and usually getting a cramp in my fingers). What can you do as a game developer to prevent the oversteering resonance catastrophe, and make driving feel right? (For a casual racing game, that doesn't strive for 100% realistic physics) I also wonder what games like Super Mario Kart exactly do differently so that they don't have so much oversteering? I guess one problem is that if you play with a keyboard or a touchscreen (but not wheels and pedals), you only have digital input: gas pressed or not, steering left/right or not, and it's much harder to steer appropriately for a given speed. The other thing is that you probably don't have a good sense of speed, and drive much faster than you would (safely) in reality. From the top of my head, one solution might be to vary the steering response with speed.

  • Multiple domain links on Google from one WordPress site

    - by user557318
    At present when I Google the domain name of the WordPress sites I have worked on, I receive at least three listings (often the top three). The first listing is the only one I am interested in seeing, others appear from individual pages from that WordPress site i.e.: 1st hit - www.domain.com 2nd hit - www.domain.com/about 3rd hit - www.domain.com/designers Does anybody know if its possible to remove all the links but the absolute www.domain.com?

  • Ubuntu 14.04 has a bunch of old kernel directories

    - by NoBugs
    I saw in Disk Usage Analyzer I have 3.13.0-xx for 8 minor versions of the kernel in /lib/modules. Each is around 200MB. I remember having to go through in Synaptic and remove those old Linux versions before, but hasn't this bug been fixed? Is it just paranoid default setting, that perhaps all of the last half dozen kernels might become unbootable, so it keeps each old one around? Or do I have some developer setting enabled by accident that causes this?

  • Conflict between Change Control and ASL Mapping

    - by Jie Chen
    Yesterday I got one strange report that on Agile 9.3.1.2, adding a Supplier into Item's Supplier tab will always remove all the data from Item.PageTwo.MultiList01 field which is assigned to a User Group list. The detailed problem description is like below. In JavaClient, MultiList01 attribute on Parts class's PageTwo tab is enabled and assigned with User Group list. On WebClient, user created a new Part and assign MultiList01 with two UserGroups: "Global User Group Test1" and "Personal Group_Test1". Then go to Suppliers tab to add three Suppliers. Switch back to Part's TitleBlock, will see MultiList01 loses the User Group data. To confirm if MultiList01 really loses the data or it saves with other wrong data, I need to check the database and find strange data that MultiList01 saves wrong data ",7976911,7976907,7976959,", which are exactly the ID of these three Suppliers. Then I can suspect the Supplier attribute on Suppliers tab must be mapped to MultiList01. However when I check Supplier in JavaClient, the "ASL mapped to" is blank. More interesting thing is the database clearly shows Supplier attribute (Base ID =2000004219) is mapped to 2090, which is PageTwo.MultiList01 Base ID. Till now, we can get a conclusion that Supplier data is really mapped to MultiList01, though we assign MultiList01 to User Group list and Supplier does not set "ASL mapped to". It must be another function which overrides "ASL mapped to" visibility in JavaClient with high priority. That is the "Change Controlled" function. We immediately see "ASL mapped to" with value "MultiList01" when we disable Change Controlled for Multilist01 If one attribute is Change Controlled, Supplier data cannot be mapped to this attribute theoretically because Supplier could be dynamically modified by users, not by Changes. In real situation of Agile 9.3.1.2, it could be a Code Defect. We can imagine the scenario customer met. He setup Parts.PageTwo.Multilist01 assigned with Supplier list, then in Parts.Suppliers.Supplier attribute, he set "ASL mapped to" to "Multilist01". Later company business is changed, so he set Multilist01 with Change Controlled and re-assign with User Group list. He forgot to remove "ASL mapped to" before he did modifications to Multilist01. Finally we know the solution, it depends on real business. If still need to mapping Supplier to Parts.PageTwo attribute, should modify "ASL mapped to" to other one attribute which already has assigned with Suppliers list. If do not need "ASL mapped to" function, should delete the data from database level. We cannot do it from JavaClient UI. delete propertytable where id in (select p.id from propertytable p, nodetable n where p.parentid =n.id and n.inherit=2000004219 and propertyid=794)

  • Fix Online Management - Which SEO Mistakes Should Be Eliminated?

    In search engines, websites are very keenly observed before being ranked and it is very obvious if we end up making certain small mistakes. However, nobody is aware about the fact that these small mistakes can cause serious blunders to their websites. The most important requirement for developers is that they should recognize their mistakes, correct them as soon as possible using good online reputation management skills and remove Google results that act against them.

  • Disable pop-up for "Faulting application" on login - Windows Server 2003

    - by Mikael Svenson
    I have a service running on a Windows 2003 server. The service executes a .exe file to process some data. Sometimes the .exe crashes due to incorrect input and it logs an error to the Application Log which is fine. If I remote login to the server I get a pop-up of the .exe file crash, for each crash which has occured since I last logged in. The crashes can safely be ignored and I'd like to ignore these pop-ups. Is there a way to disable these pop-ups?

  • DFS-R + VSS - Run VSS at all locations or one?

    - by pbarranis
    I have 4 servers, one at each office location, each sharing read/write copies of 1.5TB of data. Changes are replicated 24/7 between all 4 servers via DFS-R. All servers run Windows 2008 R2. I'm interested in implementing VSS (Volume Shadow Services) on this data. I've read that DFS-R and VSS play nicely together, but I'm left with one unanswered question: turn on VSS at all locations or just one (the headquarters). Can I run VSS at all 4 locations safely, or is it wiser to run it at just 1 location? Thanks!

  • How to go from Mainframe to the Cloud?

    - by Ruma Sanyal
    Running applications on IBM mainframes is expensive, complex, and hinders IT responsiveness. The high costs from frequent forced upgrades, long integration cycles, and complex operations infrastructures can only be alleviated by migrating away from a mainframe environment.  Further, data centers are planning for cloud enablement pinned on principles of operating at significantly lower cost, very low upfront investment, operating on commodity hardware and open, standards based systems, and decoupling of hardware, infrastructure software, and business applications. These operating principles are in direct contrast with the principles of operating businesses on mainframes. By utilizing technologies such as Oracle Tuxedo, Oracle Coherence, and Oracle GoldenGate, businesses are able to quickly and safely migrate away from their IBM mainframe environments. Further, running Oracle Tuxedo and Oracle Coherence on Oracle Exalogic, the first and only integrated cloud machine on the market, Oracle customers can not only run their applications on standards-based open systems, significantly cutting their time to market and costs, they can start their journey of cloud enabling their mainframe applications. Oracle Tuxedo re-hosting tools and techniques can provide automated migration coverage for more than 95% of mainframe application assets, at a fraction of the cost Oracle GoldenGate can migrate data from mainframe systems to open systems, eliminating risks associated with the data migration Oracle Coherence hosts transactional data in memory providing mainframe-like data performance and linear scalability Running Oracle software on top of Oracle Exalogic empowers customers to start their journey of cloud enabling their mainframe applications Join us in a series of events across the globe where you you'll learn how you can build your enterprise cloud and add tremendous value to your business. In addition, meet with Oracle experts and your peers to discuss best practices and see how successful organizations are lowering total cost of ownership and achieving rapid returns by moving to the cloud.

  • Get to Know a Candidate (6 of 25): Jill Stein&ndash;Green Party

    - by Brian Lanham
    DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Stein is a physician with degrees from Harvard College and Harvard Medical School.  She serves on the boards of Greater Boston Physicians for Social Responsibility and MassVoters for Fair Elections, and has been active with the Massachusetts Coalition for Healthy Communities Jill Stein advocates a "Green New Deal" in which renewable energy jobs would be created to address climate change and environmental issues with the objective of employing "every American willing and able to work". Citing the research of Dr. Phillip Harvey, Professor of Law & Economics at Rutgers University, as evidence of the successful economic effects of the 1930s' New Deal projects, Stein would fund the plan with a 30% reduction in the U.S. military budget, returning US troops home, and increasing taxes on areas such as capital gains, offshore tax havens and multimillion dollar real estate. Stein plans on impacting what she sees as a growing convergence of environmental crises in water, soil, fisheries and forests, through the creation of sustainable infrastructure based in clean renewable energy generation and sustainable communities principles such as increasing intra-city mass transit and inter-city railroads, creating 'complete streets' that safely encourage bike and pedestrian traffic and regional food systems based on sustainable organic agriculture The Green Party of the United States was founded in 1991 as a voluntary association of state green parties. With its founding, the Green Party of the United States became the primary national Green organization in the United States, eclipsing the Greens/Green Party USA, which emphasized non-electoral movement building. The Green Party of the United States of America emphasizes environmentalism, non-hierarchical participatory democracy, social justice, respect for diversity, peace and nonviolence. Their "Ten Key Values," which are described as non-authoritative guiding principles, are as follows: Grassroots democracy Social justice and equal opportunity Ecological wisdom Nonviolence Decentralization Community-based economics Feminism and gender equality Respect for diversity Personal and global responsibility Future focus and sustainability The Green Party does not accept donations from corporations. Thus, the party's platforms and rhetoric critique any corporate influence and control over government, media, and American society at large. Stein has access to 403 electoral votes and is a write-in candidate in GA, IN, and MS Learn more about Jill Stein and Green Party on Wikipedia.

  • How can I preview various Google services in Firefox?

    - by Travis Christian
    With iGoogle shut down I haven't been able to replicate my homepage through other services. I'm not asking for a generic replacement for iGoogle, but how to accomplish a specific use case whether through a third-party dashboard, browser extension, or some DIY solution. I need an interactive Gmail inbox, Gmail Tasks, and Google Calendar in the same Firefox tab. If hosted by a third party, they need to authenticate safely using the Google account that I am logged in with. Other widgets would be useful but I only require those Google services. I'm using Gmail itself for now but there is hardly room for the other widgets in the sidebar. Both Google Sites and igHome won't reliably load the services, especially Tasks. Netvibes requires raw login information for third-party services.

  • Setting up SSL with 389 Directory Server for LDAP authentication

    - by GioMac
    I've got 389 Directory Server running on RHEL 5 with groups, users, posix etc. RHEL clients are authenticating users with LDAP - no problems, everything works perfect, but passwords are sent in plaintext and are visible with network sniffer. So, decided to run with SSL: Created CA - got both private and public CA certificates Using CA certs: generated both of private and public certificates and combined (1st file) for 389DS according to 389DS certificate request, imported with CA public cert to 389DS from graphical console (2nd file). Enabled SSL in 389DS On the client, using authconfig-gtk enabled SSL for LDAP, specified only CA public certificate Doesn't work. Howto? What is the best way to integrate safely?

  • How to migrate exchange 2007 (sherweb) to Google Apps?

    - by Yoffe
    I need to migrate our Sherweb.com exchange 2007 services to a Google Apps account. For the process I am really not sure.. I understand I should start with creating aliases for all email accounts within the exchange server, in Google Apps, and here I'm not sure how am I supposed to explain the Exchange that the DNS have changed without losing emails.'' Second thing is: How can I safely move the up-to 3GB mailboxes from the Exchange server to the new Google Apps accounts? Must it be with Outlook data files? If so, how do I actually upload the data files into the Google Apps account? And if not, what would be a proper way to do so? Would really appreciate any kind of help.

  • How do I choose which way to enable/disable, start/stop, or check the status of a service?

    - by Glyph
    If I want to start a system installed service, I can do: # /etc/init.d/some-svc start # initctl start some-svc # service some-svc start # start some-svc If I want to disable a service from running at boot, I can do: # rm /etc/rc2.d/S99some-svc # update-rc.d some-svc disable # mv /etc/init/some-svc.conf /etc/init/some-svc.conf.disabled Then there are similarly various things I can do to enable services for starting at boot, and so on. I'm aware of the fact that upstart is a (relatively) new thing, and I know about how SysV init used to work, and I'm vaguely aware of a bunch of D-Bus nonsense, but what I don't know is how one is actually intended to interface with this stuff. For example, I don't know how to easily determine whether a service is an Upstart job or a legacy SysV thing, without actually reading through the source of its shell scripts extensively. So: if I want to start or stop a service, either at the moment or persistently, which of these tools should I use, and why? If the answer depends on some attribute (like "this service supports upstart") then how do I quickly and easily learn about that attribute of an installed package? Relatedly, are there any user interface tools which can safely and correctly interact with the modern service infrastructure (upstart, and/or whatever its sysv compatibility is)? For example, could I reliably use sysv-rc-conf to determine which services should start?

  • Installing Oracle Client 11.1.0.7 on Windows Server 2008 64-bit. What does "Install Location" and "S

    - by Anders
    I am trying to install Oracle Client 11.1.0.7 on a Windows Server 2008 64-bit. To some this might not be rocket science but I can't understand what the options under the install screen "Specify Home Details" mean. The defaults given suggest that I use Oracle Base and install software under my own account name. It also suggests that each user should have a separate Oracle Base. This seems counter intuitive to me. I am doing a server install after all. All I want to use the installation for is to connect to an Oracle Database from Reporting Services. Can I safely ignore this and just accept the defaults? What are the implications if I change the location to a common directory?

  • Auto-run script when iPad plugged in

    - by oldmankit
    The way that Ubuntu handles documents on the iPad is awesome (without any configuration required). It beats windows, even after you install iTunes. I want to have the documents in certain iPad apps automatically synced into my Dropbox directory whenever the iPad is connected by USB. The syncing is easy; getting the script to run is not. I have already read the information in various (very out-of-date) tutorials. The best I could find was here: http://askubuntu.com/a/25091/16157 I used lsusb, with the following results: Bus 002 Device 012: ID 05ac:12a2 Apple, Inc. (Please note that when an iPad is connected, Ubuntu seems to mount it to two different mount points: one for "Documents" and one for the whole iPad filesystem.

  • How to discriminate from two nodes with identical frequencies in a Huffman's tree?

    - by Omega
    Still on my quest to compress/decompress files with a Java implementation of Huffman's coding (http://en.wikipedia.org/wiki/Huffman_coding) for a school assignment. From the Wikipedia page, I quote: Create a leaf node for each symbol and add it to the priority queue. While there is more than one node in the queue: Remove the two nodes of highest priority (lowest probability) from the queue Create a new internal node with these two nodes as children and with probability equal to the sum of the two nodes' probabilities. Add the new node to the queue. The remaining node is the root node and the tree is complete. Now, emphasis: Remove the two nodes of highest priority (lowest probability) from the queue Create a new internal node with these two nodes as children and with probability equal to the sum of the two nodes' probabilities. So I have to take two nodes with the lowest frequency. What if there are multiple nodes with the same low frequency? How do I discriminate which one to use? The reason I ask this is because Wikipedia has this image: And I wanted to see if my Huffman's tree was the same. I created a file with the following content: aaaaeeee nnttmmiihhssfffouxprl And this was the result: Doesn't look so bad. But there clearly are some differences when multiple nodes have the same frequency. My questions are the following: What is Wikipedia's image doing to discriminate the nodes with the same frequency? Is my tree wrong? (Is Wikipedia's image method the one and only answer?) I guess there is one specific and strict way to do this, because for our school assignment, files that have been compressed by my program should be able to be decompressed by other classmate's programs - so there must be a "standard" or "unique" way to do it. But I'm a bit lost with that. My code is rather straightforward. It literally just follows Wikipedia's listed steps. The way my code extracts the two nodes with the lowest frequency from the queue is to iterate all nodes and if the current node has a lower frequency than any of the two "smallest" known nodes so far, then it replaces the highest one. Just like that.

  • Editing /.config/dconf/user

    - by user86322
    I am having a problem with Gnome3 (actually, I have it set to fallback mode, or Gnome 2). I have two displays and I need an X screen (I used nvidia-xconfig and nvidia-settings to do this) for each screen. However, every time I either restart X or log in, Gnome seems to be adding the objects values under /gnome/gnome-panel/layouts (ex. first time I set the two separate X screens I had clock, then log out/in, there was clock and clock1 under objects, and then log out/in there were three, clock, clock1, clock2,.......log out/in, ............30 times....clock, clock1, clock2, ......clock 42.....!! The same thing goes for top-panels, menu-bars, etc.) After a while, I found out I could remove all those using the dconf-editor, going to /gnome/gnome-panel/layouts, removing all the repetitions under fields objects-id-list and top-id-list and leaving one value of each object. This is not a solution but at least allow me to keep using Linux without so much problem. However, the problem persists every time I restart X or log in. I now finally learned about "dconf" and where the user profile settings are located (~/.config/dconf/user) and one can use "dconf" to see the keys. In my case, I need to change/remove many keys (all those clocksX, workspace-X, menu-bar-X, etc., where goes from 1 to 42 and still counting) so it's really tedious and boring to be changing one by one using "dconf write". So I found "dconf dump", which actually allow me to dump everything into a .txt file and edit the file really quick (i.e, "dconf dump / >> dump_user.txt"). The problems? Two of them: How do I "load" back "dump_user.txt" I edited into the user profile? (I read somewhere there was a "dconf reload" but reload doesn't exist as a command under "dconf") How do I stop Gnome from keep adding more objects to my desktop environment every time I log in/restart X? NOTE: The problem doesn't occur when I set the displays to use TwinView feature (i.e., the desktop is extended/shared by both displays). However, for my case I need two separate X's. Any help/suggestion would be greatly appreciated. Thanks
