  • How to make xinit run at boot - pre login

    - by javanix
    I'm running a stripped down (minimal install version) of Lucid. For some reason, xinit seems to be failing on boot and I'm not sure what logs I should start checking - normally I would go with the Xorg ones in /var/logs, but running xinit manually after login works just fine, and as far as I can tell the usual Xorg.#.# files aren't created. Can anyone give me any suggestions as to where to start looking?

    X.509 Certificate Revocation Checking Using OCSP protocol with Oracle WebLogic Server 12c | Abhijit Patil Abhijit Patil's article focuses on how to use X.509 Certificate Revocation Checking Functionality with the OCSP protocol to validate in-bound certificates. Although this article focuses on inbound OCSP validation using OCSP, Oracle WebLogic Server 12c also supports outbound OCSP validation. Leveraging Oracle Scorecard and Strategy Management for Everyday BI Needs "Oracle Scorecard and Strategy Management (OSSM) is built-upon the premise that a scorecard system should not be separate from the BI system, like many comparable tools are today," says author Kevin McGinely. "Instead of a separate application with its own data, its own data definitions, and its own front-end, Oracle made the choice to integrate OSSM directly into OBIEE."

Build and release OSB projects with Maven | Edwin Biemond "With Maven we are able to build and deploy OSB projects," says Oracle ACE Edwin Biemond. "The artifacts generated by Maven called snaphosts and releases can be automatically uploaded to a software repository.

  • Unable to download torrents when using a VPN

    - by chad
    I am running Ubuntu 13.04 and using OpenVPN and vpnbook. When I am using a VPN I am unable to download torrents. I have tried it on 3 different torrent clients (qBittorrent, Deluge, and Transmission). Deluge just says "Checking" and never begins downloading. qBittorrent says "stalled" next to the torrent and Transmission does not say anything and just doesn't download. Is there some network setting I am missing or some OpenVPN config I need to do?

  • How can I chose the depth of a quadtree?

    - by Evpok
    In a 2d world, using a quadtree to prune pairs in collision detection, how can I chose the depth of said quadtree? The world I am dealing with is mostly made of moving objects¹, so the cost of dispatching the objects between the quadtree cells matter. So what I am interested in is the balance between the gain from less collision checking and the loss from more dispatching. 1. To be completely explicit, autonomous self-replicating cells competing for food sources, in an attempt to show my pupils predator-prey dynamics and genetic evolution at work

  • Shrink NTFS Windows 7 Partition with GParted

    - by user15961
    I am running a dual-boot system with Windows 7 and Ubuntu 10.10. Initially I allocated about 20GB for my Ubuntu partition; however, I quickly ran out of that space and am now looking to expand my partition. Currently my NTFS partition (450GB) has about 130GB of free space. I tried using GParted to shrink the partition but encountered the following error. I booted into windows so I could run chkdsk but the countdown freezes at 1 upon reboot. I tried multiple methods to resolve that issue but nothing seems to work. Finally I gave up, and now I just want to know what is the best way for me to force GParted to shrink the partition regardless of the errors. I don't really have anything important and I don't mind risking the data. I just don't want to wipe the entire NTFS partition because I don't have a Windows install CD and might require Windows later on for some programs. I tried using sudo ntfsresize but that spews out the same error as GParted... Any ideas? Check and repair file system (ntfs) on /dev/sda2 00:00:09 ( ERROR ) calibrate /dev/sda2 00:00:00 ( SUCCESS ) path: /dev/sda2 start: 36944325 end: 976771119 size: 939826795 (448.14 GiB) check file system on /dev/sda2 for errors and (if possible) fix them 00:00:09 ( ERROR ) ntfsresize -P -i -f -v /dev/sda2 ntfsresize v2.0.0 (libntfs 10:0:0) Device name : /dev/sda2 NTFS volume version: 3.1 Cluster size : 4096 bytes Current volume size: 481191318016 bytes (481192 MB) Current device size: 481191319040 bytes (481192 MB) Checking for bad sectors ...

  • How to unit test with lots of IO

    - by Eric
    I write Linux embedded software which closely integrates with hardware. My modules are such as : -CMOS video input with kernel driver (v4l2) -Hardware h264/mpeg4 encoders (texas instuments) -Audio Capture/Playback (alsa) -Network IO I'd like to have automated testing for those functionalities, such as integration testing. I am not sure how I can automate this process since most of the top level functionalities I face are IO bound. Sure, it is easy to test functions individually, but whole process checking means depending on tons of external dependencies only available at runtime.

  • Defensive Error Handling

    TRY…CATCH error handling in SQL Server has certain limitations and inconsistencies that will trap the unwary developer, used to the more feature-rich error handling of client-side languages such as C# and Java. In this article, abstracted from his excellent new book, Defensive Database Programming with SQL Server, Alex Kuznetsov offers a simple, robust approach to checking and handling errors in SQL Server, with client-side error handling used to enforce what is done on the server.

  • How to get Ubuntu automatically connect to (windows, cabled & shared) network folder?

    - by Koen
    Through the normal processes I enter my shared music folder on my Windows computer, i.e.: Places Network Windows pc Music. After rebooting my Ubuntu laptop, however, this connection isn't automatically set again. My question: How do I get Ubuntu to automatically connect to that shared folder after login (while first checking whether the Windows computer is 'online')? This because I added the folder to the Banshee Library, and I currently first have to go to the shared folder manually before Banshee can play the files.

  • Once installed geos library (C++, and C), and then trying to install rgeos package (R), it reports geos-config missing!

    - by user1873888
    Knowing that the package rgeos, from the R language, requieres a prior installation of geos libraries, I installed, both, libgeos and libgeos-c1 (3.2.2), using the synaptic installer in my Ubuntu 12.04 (32 bit) machine. Then I tried to install rgeos directly from the R console, and it issued a message in the sense that geos-config was not found. The output is as follows: > install.packages("rgeos") Installing package(s) into ‘/home/checo/R/i486-pc-linux-gnu-library/2.15’ (as ‘lib’ is unspecified) also installing the dependency ‘sp’ probando la URL 'http://cran.rstudio.com/src/contrib/sp_1.0-9.tar.gz' Content type 'application/x-gzip' length 882102 bytes (861 Kb) URL abierta ================================================== downloaded 861 Kb probando la URL 'http://cran.rstudio.com/src/contrib/rgeos_0.2-19.tar.gz' Content type 'application/x-gzip' length 221471 bytes (216 Kb) URL abierta ================================================== downloaded 216 Kb * installing *source* package ‘sp’ ... ** package ‘sp’ successfully unpacked and MD5 sums checked ** libs gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c R centroid.c -o Rcentroid.o gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c gcdist.c -o gcdist.o gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c init.c -o init.o gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c pip.c -o pip.o gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c pip2.c -o pip2.o gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c sp_xports.c -o sp_xports.o gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c surfaceArea.c -o surfaceArea.o gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c zerodist.c -o zerodist.o gcc -std=gnu99 -shared -o sp.so Rcentroid.o gcdist.o init.o pip.o pip2.o sp_xports.o surfaceArea.o zerodist.o -L/usr/lib/R/lib -lR installing to /home/checo/R/i486-pc-linux-gnu-library/2.15/sp/libs ** R ** data ** demo ** inst ** preparing package for lazy loading ** help *** installing help indices ** building package indices ** installing vignettes ‘intro_sp.Rnw’ ‘over.Rnw’ ** testing if installed package can be loaded * DONE (sp) * installing *source* package ‘rgeos’ ... ** package ‘rgeos’ successfully unpacked and MD5 sums checked configure: CC: gcc -std=gnu99 configure: CXX: g++ configure: rgeos: 0.2-17 checking for /usr/bin/svnversion... no configure: svn revision: 394 checking geos-config usability... ./configure: line 1385: geos-config: command not found no configure: error: geos-config not usable ERROR: configuration failed for package ‘rgeos’ * removing ‘/home/checo/R/i486-pc-linux-gnu-library/2.15/rgeos’ Warning in install.packages : installation of package ‘rgeos’ had non-zero exit status Forgive my ignorance, but I don't know where this file, "geos-config", comes from: should it be generated by the gcc compilations above, or should it be previously installed when the libgeos libraries were intalled?

  • external USB HD doesn't show up on 'sudo fdisk -l' on one Ubuntu, shows up on another (both 'precise')

    - by Menelaos
    I have a 1.5TB WD external USB HDD and two Ubuntu systems, both 'precise'. When I plug the disk on system A it doesn't show up on the output of sudo fdisk -l nor is it automatically mounted (note that that wasn't always the case - it used to appear in the past). When I plug it on system B (again Ubuntu precise) it shows up when I do a sudo fdisk -l (output appended at the end) and mounts automatically just fine. What does this discrepancy point to and what kind of diagnostics should I run / tools I should use to troubleshoot the problem? I followed the suggestion I received to do a sudo tail -f /var/log/syslog and the output is the following when I plug, unplug and replug the USB cable on System A: Sep 14 23:27:09 thorin mtp-probe: checking bus 2, device 3: "/sys/devices/pci0000:00/0000:00:13.2/usb2/2-2" Sep 14 23:27:09 thorin mtp-probe: bus: 2, device: 3 was not an MTP device Sep 14 23:28:01 thorin kernel: [ 338.994295] usb 2-2: USB disconnect, device number 3 Sep 14 23:28:04 thorin kernel: [ 341.808139] usb 2-2: new high-speed USB device number 4 using ehci_hcd Sep 14 23:28:04 thorin mtp-probe: checking bus 2, device 4: "/sys/devices/pci0000:00/0000:00:13.2/usb2/2-2" Sep 14 23:28:04 thorin mtp-probe: bus: 2, device: 4 was not an MTP device Sep 14 23:29:54 thorin AptDaemon: INFO: Quitting due to inactivity Sep 14 23:29:54 thorin AptDaemon: INFO: Quitting was requested (I guess the last two message are irrelevant).

This has been going on for awhile now, and some animosity is starting to grow between us based upon decisions made and overall attitude toward client interactions and tasks. This person is not necessarily a bad programmer, but I can tell is mentally checking out and shutting down. Generally speaking, how do you deal with this behavior?
