• Need old version Firefox Java plugin

  - by Bryan

  I need to use Java 1.6.0_20 for the software I'm running. I went to the Oracle website and downloaded jre1.6.0_20 and installed it on my computer, but can't seem to get Firefox to load Java. If I download directly from http://www.java.com/en/download/manual.jsp, the plugin works fine but is the wrong version, and I can't find on www.java.com anywhere to download any of the previous versions. According to the help (can't post link because of spam prevention), I need to go into the Java Control Panel and enable it for Mozilla. I've done this multiple times, but every time I go in to the control panel and check the box, click Apply and Save, as soon as I go back in the box is unchecked. Does anyone know either why the box is unchecked, or where I can download the old JRE that also is configured for Firefox?

• Resume on 30 Days of SharePoint

  Dear readers, as you might have noticed... It was an organisational desaster on my end! Even though I continued my studies and research on Microsoft SharePoint 2013 during the last 30 days, I wasn't able to write an article a day to keep you posted on my progress. Nonetheless, I gathered a good number of additional blogs, mainly SharePoint MVP sites, and online forums which will be helpful in the next couple of weeks while I'm actually going to develop a C#-based client which will enable an existing 'legacy' application to SharePoint as a document management system (DMS) besides other already existing solutions. Finding excuses Well, no. Not really. I simply didn't block any or enough time every day to write down my progress during my own challenge. My log book on learning about SharePoint stands at 41 hours and 15 minutes during this month. Which means that I spent an average of more than 1 hour per day on getting into SharePoint. I know that might sound a little bit low but also keep in mind that I went for the challenge on top of my daily job and private responsibilities. During the same period there had been two priority 0 incidents from clients - external root cause - which took presedence over this leisure project. More to come Anyway, it was a first trial and despite the low level of reporting on my blog, I'm confident about what I learned during the last 30 days, and I'm ready to implement the client's requirements. At least, I would say that I have a better understanding about the road map or the path to walk during the next month. As time and secrecy allows I'm going to note down some bits and pieces... During the process of development, I'm going to 'cheat' on the challenge summary article and add links to those new entries. Just for the sake of completeness. Next challenge? Hmm, there had been ideas during the last meetup of the Mauritius Software Craftsmanship Community (MSCC) regarding certifications in IT and eventually we might organise some kind of a study group for specific exams, most probably Microsoft exams towards MCSD Web Developer or Windows Developer.

• Windows 2008 Group Policy Setting? - Migration Headache

  - by DevNULL

  I have a small domain of users that I just migrated from a linux domain running open-ldap. Our new servers are running Windows 2008 Standard. I've installed Active Directory and everything is working perfectly... except that the initial user privileges is pretty restrictive and I need to loosen it up a bit. For example once they login to their workstations, they can create new files and folders but can not modify existing files or start. I basically want to open it all up except for software installations. Can someone please help with with this migration headache?

• Ubuntu 12.10 sources.list empty after install

  - by Martin Nielsen

  I recently installed the Ubuntu 12.10 server version from a USB stick. The step "Install additional software" or whatever keeps failing, so i though screw it and continued. Everything else worked like a charm. I thought. Turns out, the only two entries in my sources.list are the install CD. This means that i have no way of getting a.. well.. anything installed. Can someone give me a short list of repositories that i need so i can put them in the file? And on a similar note: What is the comment character for the sources list? #?

• I cannot boot Ubuntu from WUBI install with windows 7, get an error message every time

  - by Tom

  i have tried several times to install ubuntu using wubi, i can't use a disc as i have a notebook computer and there is no optical drive. the download and installation all seem to work well but whenever i try to boot ubuntu at the windows 7/ubuntu menu it comes up with this error screen. I have used both the C: drive and the D: drive to install Ubuntu several times each, it's always unsuccessful. "Windows has failed to start. a recent hardware or software change might be the cause. To fix the problem: Insert your windows installation disc and restart your computer Choose your language settings and then click 'next' Click repair your computer. If you do not have this disc, contact your system administrator or computer manufacturer for assistance. File: \ubuntu\winboot\wubildr.mbr Status: 0xc000000F Info: The selected entry could not be loaded because the application is missing or corrupt." I use an ASUS x501a with windows 7. What do i do to fix this? I want to be able to dual boot Windows 7 and ubuntu. Thanks a lot :)

• Install XP over Ubuntu. (Flash Drive)

  - by Joseph

  My girlfriend needs to install Windows XP over Ubuntu on her PC, because she need to run some software that Wine and a visual machine can't handle as well as the 'real' thing. Problem is, it seems very difficult to make a bootable flash drive with the files from a XP .iso from Ubuntu. All the guides I could find was about Windows 7, formatting the USB as NTFS, then use UNetbootin to extract the files to the USB. Problem is, that only works with 7, not XP. Does anyone know how I can make a bootable XP flash drive? Thanks! It's really important.

• Do your own design jobs and make it look professional

  - by Webgui

  Looks and design is becoming more and more important for customers and organizations event when we deal with internal enterprise applications. However,  many web developers who work on business apps end up not investing resources on the design. The reason may be that they ran out of time so with their client's pressure there was no choice but to skip past the design process. In some cases, especially in sall software houses, there are no trained professional designers and the developers have to do both jobs. Since designing web applications can be very complex and requires mastering several languages and concepts, unless a big budget was allocated to the project it is very hard to produce a professional custom design. For that exact reasons, Visual WebGui integrated Point & Click Design Tools within its Web/Cloud Development Platform. Those tools allow developers to customize the UI look of the applications they build in a visual way that is fairly simple and doesn't require coding or mastering HTML, CSS and JavaScript in order to design. The development tools also allow professional designers easier work interface with the developers and quicly create new skins. So if you are interested in getting your design job done much easier, you should probably tune in for about an hour and find out how.

• HDD not detected whenever first power on (detected at BIOS level)

  - by Alvin Lim

  I am using Asus P8H61-M LX Motherboard with latest version of BIOS: 4401 One SATA-3 Western Digital Black Series 1.5TB is attached to SATA port 0 A Samsung 22x DVDRW SATA drive attached to SATA Port 1. ps/2 Logitech mouse and keyboard. CPU is i3 with DDR3 8Gb RAM. no other devices are installed. My problem is that when I turn on the computer, the WD HDD is not detected. ie cannot be booted. I have to press ctrl+alt+del in order to get it detected. I'd used the WD data lifeguard software to scan the HDD, the smart status is OK, the surface scan does not show any error at all. Where did I do wrong? Any advice is greatly appreciated.

• Shoring up deficiencies in a "home grown" programmer?

  - by JohnP

  I started out by teaching myself BASIC on a Vic 20, and in college (mid 80's) I had Fortran, Pascal, limited C, machine and assembler (With a smattering of COBOL). I didn't touch programming from approx 1989 to 1999. At that point, I was lucky enough to get hired as a Clipper programmer. Took me about 6 months to learn most of it, and by now (13 yrs) I'm pretty expert in it. I have also picked up Cold Fusion, some C#, some ASP, SQL, etc. I know programming structures, but in most languages I'm missing the esoterics, and I know my code could be much tighter. The problem is that I've learned what I needed to, to get the job done. This results in a lot of gaps in practical knowledge. I am also missing out on a TON of theory. Things like SRP, Refactoring, etc are alien terms. (Although I grok the intent after a short read). In addition, I am in the position now of teaching junior programmers the company and our software, and I don't want to pass on the knowledge gaps. I know this is somewhat of a subjective question and may be closed, but how do you go back and pick up what you've missed?

• install clamav from surceforge

  - by maria

  I'm using Ubuntu 10.04. I'm affraid I've installed a virus on my computer (I've clicked a link which was a virus), I'd prefere to check if everything is fine. I've installed clamAV using Synaptic. The installed version was 0.96.5, while the most recent version is 0.97.6. When I was trying to update virus database, I got a warning that the version of clamAV I'm using is outdated. Since I didn't know how to update the software by Synaptic or apt (both show the installed version as the newest) I've uninstalled all and downloaded the recent version from sourceforge. I've unpacked the tar.gz archive, entered the folder but when I type ./configure I'm getting the message: configure: error: Please install zlib and zlib-devel packages When I type sudo aptitude install zlib zlib-devel The terminal output says there is no such packages (there is no package zlib-devel and there is many packages which name contain zlib). I suppose the link contained probably the Windows virus, but I'd prefere to make sure there is nothing in my computer. As well as I'm not sure if the virus, even without harming my system, can send itself to my e-mail contacts or not.

• vps running out of memory, 200MB free

  - by demon

  At the beginning of this year I took a VPS for my website because I was running against the resource limits from a shared hosting. Here are the things I know: 2GB memory, with 1GB swap Debian X64 server ED installed Software running on the webserver: mysql apache postfix pop3 imap amavisd clamd cron fail2ban munin-node pure-ftpd spamd nginx Now for the setup: Nginx listens on port 80 and handles the static files, the php side is done by apache2 running mod_php in combi with apc(no var caching!). Iam using a pretty 'busy' drupal and phpbb stack on the server, for drupal iam using boost and authcache to handle of the server load with a pressflow stack. phpbb is just phpbb3 with some mods installed, but has at max 30 users online at a time.. The problem is that its staring to use the swap after a few days after a reboot and thus the site becomes slower. I'v added pictures of monit and munin, so maybe somebody can help me out...

• Joining H264 *without* re-encoding

  - by jdmuys

  I have two halves of a single show in two .MP4 files, encoded in H264. I would like to join them without re-encoding. Is this possible? I managed to create a joined video as a Quicktime file (.mov) using Quicktime Pro, but then Quicktime Pro will not convert it back to .MP4 without re-encoding. This may be because looking inside the .mov file, the two H264 videos are in there still separated as individual "objects". I am also struggling with MPEG StreamClip without reaching a real solution. But I may have missed something. Note that I do not have the same issue with MPEG2 files. I can export them to a .MPEG container or a .TS file for example, and then I can join them without re-encoding using MPEG Streamclip. Any suggestion welcome, preferably using Mac software.

• Take Complete Image of CRM Server Application

  - by nicorellius

  I have heard of snapshots or ghost images like this. But I have never used this kind of tool to actually clone a piece of hard drive. I think Norton Partition Magic can do something like this as well, but haven't tried it. So my question is this: How can I duplicate a CRM server application exactly so that I can transfer it to another system? I have a CRM server running LAMP (Linux, Apache, MySQL, and PHP) and I urgently need to transfer these data to another system without actually installing, configuring the dependencies and then doing the same for the software itself. Has anyone done this or does anyone know how to do this?

• "ODM" - One of the Support team's most valued acronyms

  - by graham.mckendry(at)oracle.com

  If you submit technical service requests (SRs) through the My Oracle Support portal, you may often see the term "ODM" used in updates from our Support team. ODM is an acronym for "Oracle Diagnostic Methodology", which defines a standard problem solving approach that all of Oracle Support uses for every technical SR. ODM provides a number of benefits to the SRs - both for the Support organization and for the customer - including a consistent approach, higher quality, justified solutions, and ultimately faster resolution. Screenshot: Example of an ODM "Issue Clarification" activity in a service request The Oracle Diagnostic Methodology applies to both categories of technical SRs: Consultative (question-answer topics) and Problem-Solution. There are a few KM Notes that describe the steps of ODM, however to keep things simple (and since those KM Notes appear to be a bit outdated), I'll summarize the ODM stages here as follows: Consultative ODM - Three mandatory stages: ODM Question: Clarification of the customer's exact question. ODM Answer: Thorough answer to the customer's question. ODM Knowledge Content: Reference to new or existing knowledge base content, or explanation why the particular SR does not necessarily require knowledge content. Problem-Solution ODM - Eight mandatory stages: ODM Issue Clarification: Clarification of the reported issue, including the symptoms, the steps to reproduce, and an outline of the business impact ODM Issue Verification: Confirmation of the issue being verified based on proof provided by the customer, such as screenshots, log files, or reproducing the issue during an Oracle Web Conference. ODM Cause Determination: Succinct outline of the root cause of the issue. ODM Cause Justification: Explanation as to why the root cause applies to this particular situation. ODM Proposed Solution(s): Succinct outline of the potential solution(s) to resolve the issue. ODM Proposed Solution(s) Justification: Explanation of why the proposed solution(s) will in fact resolve the issue. ODM Solution Action Plan: Detailed numbered instructions on how to execute the proposed solutions. ODM Knowledge Content: Reference to new or existing knowledge base content, or explanation why the particular SR does not necessarily require knowledge content. During these stages, you may see other optional ODM-related activities such as "ODM Data Collection", "ODM Action Plan", "ODM Research", and "ODM Test Case". Again, these structured tags help ensure a uniform methodology across your SRs. With this knowledge you should be able to develop better predictability of what's coming next in your SRs, as well as what you can do to help expedite the resolution process.

• Can't change folder background

  - by newcomer

  I tried to change via dragging from the Backgrounds and Emblems window, but the icon just goes back to that window rather than changing the folder background.However, I can change the task bar by this drag-n-drop. Probably it is something about changing ownership permission? if so how to change that? In /home/mashruf/.gconf/apps/nautilus/preferences/%gconf.xml file it says:, Should I change this file? how? <?xml version="1.0"?> <gconf> <entry name="click_policy" mtime="1297597800" type="string"> <stringvalue>single</stringvalue> </entry> <entry name="default_folder_viewer" mtime="1297597336" type="string"> <stringvalue>list_view</stringvalue> </entry> <entry name="media_autorun_x_content_open_folder" mtime="1297534321" type="list" ltype="string"> </entry> <entry name="media_autorun_x_content_ignore" mtime="1297534321" type="list" ltype="string"> </entry> <entry name="media_autorun_x_content_start_app" mtime="1297534321" type="list" ltype="string"> <li type="string"> <stringvalue>x-content/software</stringvalue> </li> </entry> <entry name="start_with_location_bar" mtime="1297300028" type="bool" value="true"/> <entry name="side_pane_view" mtime="1297269334" type="string"> <stringvalue>NautilusTreeSidebar</stringvalue> </entry> <entry name="navigation_window_saved_maximized" mtime="1297600306" type="bool" value="false"/> <entry name="navigation_window_saved_geometry" mtime="1297600306" type="string"> <stringvalue>964x608+59+2</stringvalue> </entry> <entry name="sidebar_width" mtime="1297390418" type="int" value="192"/> </gconf>

• postfix cannot send email

• How to verify the code that could take a substantial time to compile? [on hold]

  - by user18404

  As a follow up to my prev question: What is the best aproach for coding in a slow compilation environment To recap: I am stuck with a large software system with which a TDD ideology of "test often" does not work. And to make it even worse the features like pre-compiled headers/multi-threaded compilation/incremental linking, etc is not available to me - hence I think that the best way out would be to add the extensive logging into the system and to start "coding in large chunks", which I understand as code for a two-three hours first (as opposed to 15-20 mins in TDD) - thoroughly eyeball the code for a 15 minutes and only after all that do the compilation and run the tests. As I have been doing TDD for a quite a while, my code eyeballing / code verification skills got rusty (you don't really need this that much if you can quickly verify what you've done in 5 seconds by running a test or two) - so I am after a recommendations on how to learn these source code verification/error spotting skills again. I know I was able to do that easily some 5-10 years ago when I din't have much support from the compiler/unit testing tools I had until recently, thus there should be a way to get back to the basics.

• Error from DNS validation service: RFC821 4.3

  So I've managed to setup bind9 and a mail server, but it seems there is something wrong. I don't quite under stand this error: The configuration of your mail servers and your DNS are not ok! The report of the test is: mail.domain.com. - mail.domain.com - 208.xxx.xxx.xxx - lisa.domain.com Spam recognition software and RFC821 4.3 (also RFC2821 4.3.1) state that the hostname given in the SMTP greeting MUST have an A record pointing back to the same server. Can anyone explain this to me in a bit more detail, and maybe point me in a direction to solve this?

• How to fix incorrect margins when printing from Windows 7?

• Setup local EC2 style cloud?

  - by John Kramlich

  I was recently given 3 dual opteron 2400 servers with 4GB of RAM and 120GB hard drives. I am interested in setting up something similar to Amazon's EC2 for my own personal web development use. Basically, I would like to spin up instances from an ISO or other disk images and have them available to test and develop software. Are there open source solutions I can use to accomplish this? I am assuming one of the machines will need to act as a controller of some sort for the other two. I use Sun's VirtualBox on my local development machine to virtualize various versions of Microsoft Windows. However, I'm not sure if that's the best tool for what I am trying to achieve. I apologize in advance if this question is to vague to get meaningful responses. I am new to cloud computing and fairly new at server administration.

• What to learn after standard C++?

  - by Luca Cerone

  I switched to C++ a few months ago, learning its syntax, the main features of the STL and what you can usually find in a "learn C++" manual. Now I would like to go further. What would be your recommendations? I would like to know what to learn next (not only about the language, but also debugging, frameworks etc. etc.) I know probably the answer depends on the specific needs of each user, so here is a list of mine: Cross Platform development Developing GUI for my programs Develop extendible software, allowing the use of plugins Use of scientific libraries Interact with databases (mainly MySQL) Having server/client functionalities (I'd like users of my programs to interact through internet.. as you might have guessed I am not a programmer by training so I might have used the wrong terms.. if so I apologize for that). Of course I know it takes time, but I would like to have a good list of references and resources to start (both books and websites are ok). Thanks a lot for your help!

• Engineered Systems and PCI

  - by Joel Weise

  Oracle has a number of different engineered systems.  These are design to be highly integrated, optimized and secure systems.  The Exadata database engineered system and the Exalogic application engineered system are two good examples.  Often I am asked how these comply with different standards and regulations.  Exalogic is the Oracle engineered system that supports applications and the focus of today's blog.  First, we must recognize that as a collection of hardware and software, we cannot simply state that Exalogic is "compliant" with PCI DSS.  This is because Exalogic must be implemented within the context of one's existing IT infrastructure, the security features of that infrastructure, the governance framework that exists, security policies, operational procedures, and other factors.  What we can say though, is that Exalogic has been designed with various security capabilities that can be utilized to support compliance to PCI DSS as well as other standards and regulations (e.g., NIST and HIPAA).  Given that, Exalogic can be an excellant platform for running PCI related payment applications.  Coalfire Systems, a leading QSA in the US, has evaluated Exalogic against PCI DSS and supports this position.  Their evaluation can be found here: Exalogic and PCI Compliance. I hope you find it useful.

• Video problem with Windows 7 Games

  - by Jordan 1GT

  I have a Dell xps M1330 which originally ran Vista, but I upgraded to Windows 7. When I try to run a Win 7 game like spider solitaire I receive the following message: "The game is running in software rendering mode. Hardware acceleration is either disabled or not supported by your video card driver which could slow down game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on." I confirmed that hardware acceleration is turned on. When I go to Dell's site, I'm told there is no later video driver. When I run the game it runs very choppy. I wouldn't care, but I loaded a .pptx file which is doing strange things in normal view and I suspect may be related to the same video problem. Any ideas?

• Standalone server setup for compute capacity

  - by mikera

  I'm developing an application for my company that will require a lot of compute capacity (running some very big mathematical calculations), and looking for some form of server setup to do this. For various reasons, we want to run this on-site in our office rather than hosting it externally. It's been a while since I last had to set up my own servers so I thought I would tap into the collective wisdom of serverfault! My broad requirements are: Budget $30-50k, with an aim to get as much compute capacity as possible for that budget 64-bit servers suitable to run Ubuntu Linux + Java Some relatively standalone rack that can be installed in secure office space Fast/low latency network connections between the servers, but don't really care about connectivity to the outside world Storage capacity shared between the servers - they don't necessarily need their own storage providing they can be booted from a common image Downtime can be tolerated (since the calculations are run in batch mode) The software itself is fault-tolerant, so there is no need for extra resiliency in the server setup (cheap replaceable commodity parts will be fine in general) Given these requirements what kind of setup would you recommend and why?
