  • How do I fix this installation problem with multicore Solr on Ubuntu 10.04?

    - by coleifer
    Following instructions from the two sites below, I've installed Tomcat 6 and Solr 1.4. http://gist.github.com/204638 https://wiki.fourkitchens.com/display/TECH/Solr+1.4+on+Ubuntu+9.10+and+CentOS+5 I have successfully got it up and running on a server running 9.04 with multicore support, but on the 10.04 I can't seem to get it to work. I am able to reach localhost:xxxx/solr/ on the 10.04 box and see a single link to the Solr Admin, but following the link takes me to a 404 page with the following output: /solr/admin/ HTTP Status 404 - missing core name in path The requested resource (missing core name in path) is not available I am also unable to access /solr/site1/ as I would except - it similarly returns a 404. <!-- from /var/solr/solr.xml, site dirs exist --> <cores adminPath="/admin/cores"> <core name="site1" instanceDir="site1" /> <core name="site2" instanceDir="site2" /> </cores> <!-- from /etc/tomcat6/Catalina/localhost/solr.xml --> <Context docBase="/var/solr/solr.war" debug="0" privileged="true" allowLinking="true" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/var/solr" override="true" /> </Context>

  • How can I build the Boost.Python example on Ubuntu 9.10?

    - by Gatlin
    I am using Ubuntu 9.10 beta, whose repositories contain boost 1.38. I would like to build the hello-world example. I followed the instructions here (http://www.boost.org/doc/libs/1%5F40%5F0/libs/python/doc/tutorial/doc/html/python/hello.html), found the example project, and issued the "bjam" command. I have installed bjam and boost-build. I get the following output: Jamroot:18: in modules.load rule python-extension unknown in module Jamfile</usr/share/doc/libboost1.38-doc/examples/libs/python/example>. /usr/share/boost-build/build/project.jam:312: in load-jamfile /usr/share/boost-build/build/project.jam:68: in load /usr/share/boost-build/build/project.jam:170: in project.find /usr/share/boost-build/build-system.jam:248: in load /usr/share/boost-build/kernel/modules.jam:261: in import /usr/share/boost-build/kernel/bootstrap.jam:132: in boost-build /usr/share/doc/libboost1.38-doc/examples/libs/python/example/boost-build.jam:7: in module scope I do not know enough about Boost (this is an exploratory exercise for myself) to understand why the python-extension macro in the included Jamroot is not valid. I am running this example from the install directory, so I have not altered the Jamroot's use-project setting. As a side question, if I were to just willy-nilly start a project in an arbitrary directory, how would I write my jamroot?

  • Using Android on a PND(portable nagigation device)?

    - by user322202
    Hi, i'm looking for a PND on which i can install android. For example: http://www.medion.com/de/electronics/prod/MEDION%C2%AE+GoPal%C2%AE+P4440+EU/30010109A1?category=navigation_28&recId=&wt_mc=de.intern.m-shop.pro-pla.on-ma&wt_cc1=m-shop_topseller_navigation-2-links&wt_cc2=30010109A1&wt_cw=30.2.8&utm_source=Internetseite-intern&utm_medium=Kachel&utm_content=navigation_2-links&utm_campaign=Kategoriekachel-Hotspots&utm_term=30010109A1 I would like to install Android - not on a mobile phone, like it’s commonly down - but on a navigation device. In doing so I want to completely remove the old operating system and replace it with Android. Is this even possible, provided the hardware matches Android’s requirements, or are there other criteria to be aware of ? Unfortunately I have not found any implementations of this kind yet and am therefore hoping that you can provide me with some help in this regard. Sincerely yours, Christian

  • Portable way of finding total disk size in Java (pre java 6)

    - by Wouter Lievens
    I need to find the total size of a drive in Java 5 (or 1.5, whatever). I know that Java 6 has a new method in java.io.File, but I need it to work in Java 5. Apache Commons IO has org.apache.commons.io.FileSystemUtils to provide the free disk space, but not the total disk space. I realize this is OS dependant and will need to depend on messy command line invocation. I'm fine with it working on "most" systems, i.e. windows/linux/macosx. Preferably I'd like to use an existing library rather than write my own variants. Any thoughts? Thanks.

  • How to make a CodeIgniter project portable with redirects

    - by Jono
    I would like to set up my codeigniter projects so I can use it in any folder on my webserver. Unfortunately codeigniter requires me to specify the location in several variables of the config. This is a problem for portability. There are 3 places where I see this: 1) $config['base_url'] 2) $config['base_path'] 3) .htaccess RewriteRule So far, I have found the solution to (1) here: http://codeigniter.com/wiki/Automatic_base_url/ I am looking for solutions to (2) and (3), but most importantly (3). Here is an example situation: I set .htaccess to have the RewriteRule as follows: RewriteRule ^(.*)$ /folderA/index.php/$1 [L] Then I go into my repo and check out the project to another folder to make some separate changes. Now I have to update .htaccess to show the following: RewriteRule ^(.*)$ /folderB/index.php/$1 [L] I would like to set it so I dont have to make any config changes when I check out another copy.

  • Portable way to determining of printer is physical or virtual

    - by Mud
    I need direct-to-printer functionality for my website, with the ability to distinguish a physical printer from a virtual printer (file). Coupons.com has this functionality via a native binary which must be installed by the user. I'd prefer to avoid that. SmartSource.com does it via Java applet: Does anybody know how this is done? I dug through that Java APIs a bit, and don't see anything that would let you determine physical vs virtual, except looking at the name (that seems prone to misidentification). It would be nice to be able to do it in Java, because I already know how to write Java applets. Failing that, is there a way to do this in Flash or Silverlight? Thanks in advance. EDIT: Well deserved bounty awarded to Jason Sperske who worked out an elegant solution. Thanks to those of you who shared ideas, as well as those who actually investigated SmartSource.com's solution (like Adrian).

  • Looking for a safe, portable password-storage method

    - by Maciek
    Hello, I'm working on C++ project that is supposed to run on both Win32 and Linux, the software is to be deployed to small computers, usually working in remote locations. Recently, our client has requested that we introduce access control via password protection. We are to meet the following criteria : Support remote login Support remote password change Support remote password retrieval Support data retrieval on accidental/purposeful deletion Support secure storage I'm capable of meeting the "remote" requirements using an existing library, however what I do need to consider is a method of storing this data, preferably in a way that will work on both platforms and will not let the user see it/read it, encryption is not the issue here - it's the storage method itself. Can anyone recommend a sage storage method that could help me meet those criteria?

  • is memset(ary,0,length) a portable way of inputting zero in double array

    - by monkeyking
    The following code uses memset to set all the bits to zero #include <iostream> #include <cstring> int main(){ int length = 5; double *array = new double[length]; memset(array,0,sizeof(double)*length); for(int i=0;i<length;i++) if(array[i]!=0.0) std::cerr<< "not zero in: " <<i <<std::endl; return 0; } Can I assume that this will work on all platforms? Does the double datatype always correspond to the ieee-754 standard? thanks

  • Portable way to determine the platform's line separator

    - by Adrian McCarthy
    Different platforms use different line separator schemes (LF, CR-LF, CR, NEL, Unicode LINE SEPARATOR, etc.). C++ (and C) make a lot of this transparent to most programs, by converting '\n' to and from the target platform's native new line encoding. But if your program needs to determine the actual byte sequence used, how could you do it portably? The best method I've come up with is: Write a temporary file in text mode with just '\n' in it, letting the run-time do the translation. Read back the temporary file in binary mode to see the actual bytes. That feels kludgy. Is there a way to do it without temporary files? I tried stringstreams instead, but the run-time doesn't actually translate '\n' in that context (which makes sense). Does the run-time expose this information in some other way?

  • Portable Eclipse

    - by Jeach
    I'm trying to port my entire 'workspace' to a USB key (including the Eclipse executable) so that I can carry my work anywhere with me and work off the key directly. My directory hierarchy is similar to this: /workspace/eclipse - Where my current eclipse binary is stored /workspace/codebase - Where I keep the root of all my eclipse projects /workspace/resources - Where I keep all project files (images, docs, libs, etc.) It all works perfectly fine on one system. But when I change over to another system, the USB key gets mounted on another drive. For example, on my laptop, I get 'E:\', on my PC, I get 'K:\' and at work I get 'F:\', etc, etc. This means that because Eclipse (for 'some' reason) seems to only use full path names (including driver letters) in every single one of its configuration files (such as .classpath), nothing ever works when I want to work on another system. I put a 'libs' directory in the base of every project and populate it with its dependent JAR files. Why doesn't it use relative names instead, so that I could specify something like "../../libs/log4j.jar"? Anyone know how to fix this problem? Does anyone know of a workaround for this? For some reason, I really doubt I'm the first developer to do this! Thanks for your help and any suggestions.

  • portable way to deal with 64/32 bit time_t

    - by MK
    I have some code which is built both on Windows and Linux. Linux at this point is always 32bit but Windows is 32 and 64bit. Windows wants to have time_t be 64 bit and Linux still has it as 32 bit. I'm fine with that, except in some places time_t values are converted to strings. So when time_T is 32 bit it should be done with %d and when it is 64bit with %lld... what is the smart way to do this? Also: any ideas how I may find all places where time_t's are passed to printf-style functions to address this issue?

  • Portable way to get file size in C/C++

    - by chmike
    I need to determin the byte size of a file. The coding language is C++ and the code should work with Linux, windows and any other operating system. This implies using standard C or C++ functions/classes. This trivial need has apparently no trivial solution.

  • Why is my dual-boot Ubuntu partition showing up as a peripheral "root.disk"?

    - by Don
    I recently installed Ubuntu 12.04, which I had been booting from a usb key, as a dual-boot on my machine running Windows 7. From what I had read online while researching, I was prepared to have to shrink the Windows partition and all that. But I never had to - it really was just a few clicks here and there and it was installed. I'm still pretty confused about it, but whatever, it worked, and the two peacefully coexist on my machine, and I have broken things to fix before I worry about fixing unbroken things. So yesterday I got it in my head to look at my partitions (I was considering making an all new partition to install the Windows 8 Release Preview). What I saw confused me. Here's a screenshot of the disk utility. At this moment, there is nothing connected to my computer, and nothing in any of the optical drives/ports/card readers/etc. Can you help me figure out what's going on here? Don's Machine is, I believe, my Windows partition - that's the name I assigned my machine from Windows Explorer. PQSERVICE is from what I can find online also Windows, but having to do with backup. And SYSTEM REQUIRED, if I browse it in Ubuntu, is definitely something to do with booting, and I believe it is also Windows'. According to the sizes shown, those three together should use up my 500 GB HD. Then further down, as a "peripheral device", it lists that 31 GB disk. This is obviously my Ubuntu (Model:Linux Loop:root.disk), but why is it showing up as a peripheral? So, to sum up those questions and to add some more random ones I had: Why is Ubuntu showing up as a peripheral device? If the Windows sections take up all 500 GB, where does Ubuntu live? If I renamed the disk partitions, would my life become a nightmare (seriously - can I safely rename them)? Why didn't I have to resize the Windows partition in the first place? Would giving Ubuntu more space improve its performance (it hangs alot)? Is it possible to have a partition for each OS (Windows 7 & 8, Ubuntu), a partition for files, and a separate partition for backups? Is this towards the good or bad idea end of the spectrum? @Elfy, would that explain why it keeps hanging? I guess I'll backup my files, rip it out, and reinstall it correctly later on today.
