  • "Unrecoverable error" during installation

    - by Sal
    I have an old Dell computer and I want to switch from windows xp and install the new ubuntu. I have tried multiple times to download it via cd-r but keep getting the same error message: unrecoverable error. The error happens after the menu which lists try ubuntu, install ubuntu, etc.It only gets as far as the Screen with a toolbar on the top that includes power, sound, and two arrows. That is when the message displays. switching to desktop version to find what the problem is( or something like that.) What is going wrong?

  • Windows XP with Ubuntu 14.04 on 2 separate hard drives

    - by maplenet2
    I am new to Ubuntu. I have Windows XP Professional 32-bit on one 300GB IDE hard drive and Ubuntu 14.04 running on another 61GB IDE hard drive, and I cannot get my Windows XP to boot with Grub! When I select Windows XP from the boot menu, Grub just restarts my computer. The computer I have with those two hard drives is a Dell Optiplex GX240, so the hardware is old, and its BIOS won't let me change the boot priority on the two IDE hard drives. What can I do now? Is there a step I missed when installing Ubuntu? Can I edit Grub to boot Windows XP without messing with the BIOS? Do I have to downgrade to an older release of Ubuntu to make it work? I am willing to reinstall Ubuntu, if that's what it takes.

  • Is the slow performance of programming languages a bad thing?

    - by Emanuil
    Here's how I see it. There's machine code and it's all that the computers needs in order to run something. The computers don't care about programming languages. It doesn't matter to them if the machine code comes from Perl, Python or PHP. Programming languages exist to serve programmers. Some programming languages run slower than others but that's not necessarily because there is something wrong with them. In many cases it's just because they do more things that otherwise programmers would have to do and by doing these things, they do better what they are supposed to do - serve programmers. So is the slower performance (at runtime) of a programming language really a bad thing?

  • Evaluating mean and std as simulations are added

    - by Luca Cerone
    I have simulations that evaluate a certain value X. I run the simulations several times and save the value of X in a vector V. When all the runs have finished I evaluate the mean and standard deviation for the vector V. This approach works, but implies saving all the values for X. As my computer is quite old and with limited ram, I was wondering if there is a way to update the mean value M and the standard deviation S, knowing the value of X at the (n+1)-th run, and the values of M and S after n runs. How can I update the mean value and the standard deviation as simulations are added to the set? Please note that this is just a conceptual example, I don't save only one number X but thousands at each simulations, so I really have problems running a big number of runs if I have to keep all the past values into the memory.

  • Does the LGPL allow me to do this?

    - by user1229892
    I am planning to develop a commercial software using a LGPL software. In the LGPL software that I am using some functions in a class are not fully implemented. I want to modify the LGPL code so that the class and not-implemented functions are made visible outside the dll by adding dllexport infront of class and by adding virtual keyword infront of function. Then I plan to implement those functions in my proprietary software. I am ready to distribute the modified LGPL code but not proprietary software that implements functions in the way I want. Does that violate LGPL terms and conditions?

  • ORA-7445 Troubleshooting

    - by [email protected]
        QUICKLINK: Note 153788.1 ORA-600/ORA-7445 Lookup tool Note 1082674.1 : A Video To Demonstrate The Usage Of The ORA-600/ORA-7445 Lookup Tool [Video]   Have you observed an ORA-07445 error reported in your alert log? While the ORA-600 error is "captured" as a handled exception in the Oracle source code, the ORA-7445 is an unhandled exception error due to an OS exception which should result in the creation of a core file.  An ORA-7445 is a generic error, and can occur from anywhere in the Oracle code. The precise location of the error is identified by the core file and/or trace file it produces.  Looking for the best way to diagnose? Whenever an ORA-7445 error is raised a core file is generated.  There may be a trace file generated with the error as well.   Prior to 11g, the core files are located in the CORE_DUMP_DEST directory.   Starting with 11g, there is a new advanced fault diagnosability infrastructure to manage trace data.  Diagnostic files are written into a root directory for all diagnostic data called the ADR home.   Core files at 11g will go to the ADR HOME/cdump directory.   For more information on the Oracle 11g Diagnosability feature see Note 453125.1 11g Diagnosability Frequently Asked Questions Note 443529.1 11g Quick Steps to Package and Send Critical Error Diagnostic Information to Support[Video]   NOTE:  While the core file is captured in the Diagnosability infrastructure, the file may not be included with a diagnostic package.1.  Check the Alert LogThe alert log may indicate additional errors or other internal errors at the time of the problem.   In some cases, the ORA-7445 error will occur along with ORA-600, ORA-3113, ORA-4030 errors.  The ORA-7445 error can be side effects of the other problems and you should review the first error and associated core file or trace file and work down the list of errors.   Note 1020463.6 DIAGNOSING ORA-3113 ERRORS Note 1812.1 TECH:  Getting a Stack Trace from a CORE file Note 414966.1 RDA Documentation Index   If the ORA-7445 errors are not associated with other error conditions, ensure the trace data is not truncated. If you see a message at the end of the file   "MAX DUMP FILE SIZE EXCEEDED"   the MAX_DUMP_FILE_SIZE parameter is not setup high enough or to 'unlimited'. There could be vital diagnostic information missing in the file and discovering the root issue may be very difficult.  Set the MAX_DUMP_FILE_SIZE appropriately and regenerate the error for complete trace information. For pointers on deeper analysis of these errors see   Note 390293.1 Introduction to 600/7445 Internal Error Analysis Note 211909.1 Customer Introduction to ORA-7445 Errors 2.  Search 600/7445 Lookup Tool Visit My Oracle Support to access the ORA-00600 Lookup tool (Note 153788.1). The ORA-600/ORA-7445 Lookup tool may lead you to applicable content in My Oracle Support on the problem and can be used to investigate the problem with argument data from the error message or you can pull out key stack pointers from the associated trace file to match up against known bugs.3.  "Fine tune" searches in Knowledge Base As the ORA-7445 error indicates an unhandled exception in the Oracle source code, your search in the Oracle Knowledge Base will need to focus on the stack data from the core file or the trace file. Keep in mind that searches on generic argument data will bring back a large result set.  The more you can learn about the environment and code leading to the errors, the easier it will be to narrow the hit list to match your problem.

  • The Oracle Cash Management Secret Very Few Customers Know About

    - by Theresa Hickman
    Did you know that Oracle Cash Management has a robust positioning feature? I had no idea. I was under the mistaken impression that Oracle Cash Management only did bank statement reconciliations. It seems I am not alone. In fact, many Oracle Financials customers are also not aware of this even though it is delivered for free with the Oracle Financials license. Even better, last week, Oracle released an enhancement to Oracle Cash Management for Release 12 that will greatly help customers with their cash positioning needs. As we all know, credit is tight these days. Companies need better visibility of their cash and other liquidity positions to make better use of their cash resources. Today, many customers are managing their cash positions manually using spreadsheets. We also hear how many of them are maintaining larger than normal balances in numerous bank accounts because they just do not have the visibility, and therefore the comfort they need. Although spreadsheets may work in the short-term, they are not the best way to manage your cash positions for the long-term especially if you have dozens, or even hundreds of bank and brokerage accounts. Also, spreadsheets are a lot more risky because they can be overwritten, deleted, difficult to audit, etc. With the newly enhanced positioning feature in Oracle Cash Management, customers can manage their daily cash positions using an excel-like interface that is very flexible and user-configurable. You can link the worksheet to an unlimited number of bank accounts to automatically retrieve your opening balances, the current/intra-day cash inflows and outflows, as well as your expected cash flows from your Fx, Investment and Debt positions if you have Oracle's Treasury module . Oracle Cash Management also has direct integration with Oracle Receivables, Oracle Payables, and Payroll, which adds to the comprehensive picture of what's happening with your organizations' cash in real-time. Here's a screen shot of what the cash positioning page looks like: View image As you can see, your Treasurers can obtain a holistic view of all cash positions across any number of bank accounts as well as other sources of cash flow movements. Depending on how they manage their accounts, they can also use this feature to initiate or monitor bank account sweeps or transfers between their zero balance accounts (ZBA) or cash pools. The cash position worksheet provide drill down for more detail and the ability to manually enter items directly into the worksheet for even greater flexibility and control. The enhancements to this feature were released last week. The following list the patches for Release 12.0.6 and 12.1.1: For more information, visit the following website. http://launch.oracle.com.

  • What is a resonable workflow for designing webapps?

    - by Evan Plaice
    It has been a while since I have done any substantial web development and I'd like to take advantage of the latest practices but I'm struggling to visualize the workflow to incorporate everything. Here's what I'm looking to use: CakePHP framework jsmin (JavaScript Minify) SASS (Synctactically Awesome StyleSheets) Git CakePHP: Pretty self explanatory, make modifications and update the source. jsmin: When you modify a script, do you manually run jsmin to output the new minified code, or would it be better to run a pre-commit hook that automatically generates jsmin outputs of javascript files that have changed. Assume that I have no knowledge of implementing commit hooks. SASS: I really like what SASS has to offer but I'm also aware that SASS code isn't supported by browsers by default so, at some point, the SASS code needs to be transformed to normal CSS. At what point in the workflow is this done. Git I'm terrified to admit it but, the last time I did any substantial web development, I didn't use SCM source control (IE, I did use source control but it consisted of a very detailed change log with backups). I have since had plenty of experience using Git (as well as mercurial and SVN) for desktop development but I'm wondering how to best implement it for web development). Is it common practice to implement a remote repository on the web host so I can push the changes directly to the production server, or is there some cross platform (windows/linux) tool that makes it easy to upload only changed files to the production server. Are there web hosting companies that make it eas to implement a remote repository, do I need SSH access, etc... I know how to accomplish this on my own testing server with a remote repository with a separate remote tracking branch already but I've never done it on a remote production web hosting server before so I'm not aware of the options yet. Extra: I was considering implementing a javascript framework where separate javascript files used on a page are compiled into a single file for each page on the production server to limit the number of file downloads needed per page. Does something like this already exist? Is there already an open source project out in the wild that implements something similar that I could use and contribute to? Considering how paranoid web devs are about performance (and the fact that the number of file requests on a website is a big hit to performance) I'm guessing that there is some wizard hacker on the net who has already addressed this issue.

  • Imaging: Paper Paper Everywhere, but None Should be in Sight

    - by Kellsey Ruppel
    Author: Vikrant Korde, Technical Architect, Aurionpro's Oracle Implementation Services team My wedding photos are stored in several empty shoeboxes. Yes...I got married before digital photography was mainstream...which means I'm old. But my parents are really old. They have shoeboxes filled with vacation photos on slides (I doubt many of you have even seen a home slide projector...and I hope you never do!). Neither me nor my parents should have shoeboxes filled with any form of photographs whatsoever. They should obviously live in the digital world...with no physical versions in sight (other than a few framed on our walls). Businesses grapple with similar challenges. But instead of shoeboxes, they have file cabinets and warehouses jam packed with paper invoices, legal documents, human resource files, material safety data sheets, incident reports, and the list goes on and on. In fact, regulatory and compliance rules govern many industries, requiring that this paperwork is available for any number of years. It's a real challenge...especially trying to find archived documents quickly and many times with no backup. Which brings us to a set of technologies called Image Process Management (or simply Imaging or Image Processing) that are transforming these antiquated, paper-based processes. Oracle's WebCenter Content Imaging solution is a combination of their WebCenter suite, which offers a robust set of content and document management features, and their Business Process Management (BPM) suite, which helps to automate business processes through the definition of workflows and business rules. Overall, the solution provides an enterprise-class platform for end-to-end management of document images within transactional business processes. It's a solution that provides all of the capabilities needed - from document capture and recognition, to imaging and workflow - to effectively transform your ‘shoeboxes’ of files into digitally managed assets that comply with strict industry regulations. The terminology can be quite overwhelming if you're new to the space, so we've provided a summary of the primary components of the solution below, along with a short description of the two paths that can be executed to load images of scanned documents into Oracle's WebCenter suite. WebCenter Imaging (WCI): the electronic document repository that provides security, annotations, and search capabilities, and is the primary user interface for managing work items in the imaging solution SOA & BPM Suites (workflow): provide business process management capabilities, including human tasks, workflow management, service integration, and all other standard SOA features. It's interesting to note that there a number of 'jumpstart' processes available to help accelerate the integration of business applications, such as the accounts payable invoice processing solution for E-Business Suite that facilitates the processing of large volumes of invoices WebCenter Enterprise Capture (WEC): expedites the capture process of paper documents to digital images, offering high volume scanning and importing from email, and allows for flexible indexing options WebCenter Forms Recognition (WFR): automatically recognizes, categorizes, and extracts information from paper documents with greatly reduced human intervention WebCenter Content: the backend content server that provides versioning, security, and content storage There are two paths that can be executed to send data from WebCenter Capture to WebCenter Imaging, both of which are described below: 1. Direct Flow - This is the simplest and quickest way to push an image scanned from WebCenter Enterprise Capture (WEC) to WebCenter Imaging (WCI), using the bare minimum metadata. The WEC activities are defined below: The paper document is scanned (or imported from email). The scanned image is indexed using a predefined indexing profile. The image is committed directly into the process flow 2. WFR (WebCenter Forms Recognition) Flow - This is the more complex process, during which data is extracted from the image using a series of operations including Optical Character Recognition (OCR), Classification, Extraction, and Export. This process creates three files (Tiff, XML, and TXT), which are fed to the WCI Input Agent (the high speed import/filing module). The WCI Input Agent directory is a standard ingestion method for adding content to WebCenter Imaging, the process for doing so is described below: WEC commits the batch using the respective commit profile. A TIFF file is created, passing data through the file name by including values separated by "_" (underscores). WFR completes OCR, classification, extraction, export, and pulls the data from the image. In addition to the TIFF file, which contains the document image, an XML file containing the extracted data, and a TXT file containing the metadata that will be filled in WCI, are also created. All three files are exported to WCI's Input agent directory. Based on previously defined "input masks", the WCI Input Agent will pick up the seeding file (often the TXT file). Finally, the TIFF file is pushed in UCM and a unique web-viewable URL is created. Based on the mapping data read from the TXT file, a new record is created in the WCI application.  Although these processes may seem complex, each Oracle component works seamlessly together to achieve a high performing and scalable platform. The solution has been field tested at some of the largest enterprises in the world and has transformed millions and millions of paper-based documents to more easily manageable digital assets.

  • Could anyone help me get my NETGEAR WNA3100 (Broadcom BCM43231) wireless adapter to work?

    - by Matthew Carroll
    I have just moved back to Ubuntu from Windows 7 and a few months ago, I bought a NETGEAR WNA3100 wireless adapter because my old adapter had broken. I plugged in my adapter and it doesn't seem to work, I also used the windows 7 drivers for it and tried them on the program "Windows Wireless Drivers" and they don't seem to recognize the device. However I have heard you need XP drivers but I can't seem to find them on the internet nor find them on the CD. Could anyone help me get my wireless adapter to work? Any help is greatly appreciate. P.S I do have internet connection though I have to tether my phone to my computer and then connect my phone to my router.

  • Geometry Shader input vertices order

    - by NPS
    MSDN specifies (link) that when using triangleadj type of input to the GS, it should provide me with 6 vertices in specific order: 1st vertex of the triangle processed, vertex of an adjacent triangle, 2nd vertex of the triangle processed, another vertex of an adjacent triangle and so on... So if I wanted to create a pass-through shader (i.e. output the same triangle I got on input and nothing else) I should return vertices 0, 2 and 4. Is that correct? Well, apparently it isn't because I did just that and when I ran my app the vertices were flickering (like changing positions/disappearing/showing again or sth like that). But when I instead output vertices 0, 1 and 2 the app rendered the mesh correctly. I could provide some code but it seems like the problem is in the input vertices order, not the code itself. So what order do input vertices to the GS come in?

  • Are there any non-self-taught famous programmers? [closed]

    - by Jon Purdy
    It seems to me that being a self-taught programmer has significant advantages over picking it up only in higher education. Not only does a self-taught developer have a headstart on their 10 000-odd hours of mastery, but their hobby demonstrates genuine interest. This will likely lead to a process of continuous self-improvement over their career, not to mention increased likelihood of producing personal projects that are worthy of fame. A programmer who spends four years in study (not nearly all of which is going to be directly concerned with programming) has far less leisure to explore and learn independently than does a developer who starts college with even a few years of dedicated hobbyist study. I wonder whether there are any famed developers who had no exposure to programming before deciding to study it in university. I simply doubt that an 18-year-old has the capacity to become a brilliant programmer with no prior experience, but that seems like an awfully elitist and unpleasant view, so I'd like to be proven wrong.

  • Playing a Song causing WP7 to crash on phone, but not on emulator

    - by Michael Zehnich
    Hi there, I am trying to implement a song into a game that begins playing and continually loops on Windows Phone 7 via XNA 4.0. On the emulator, this works fine, however when deployed to a phone, it simply gives a black screen before going back to the home screen. Here is the rogue code in question, and commenting this code out makes the app run fine on the phone: // in the constructor fields private Song song; // in the LoadContent() method song = Content.Load<Song>("song"); // in the Update() method if (MediaPlayer.GameHasControl && MediaPlayer.State != MediaState.Playing) { MediaPlayer.Play(song); } The song file itself is a 2:53 long, 2.28mb .wma file at 106kbps bitrate. Again this works perfectly on emulator but does not run at all on phone. Thanks for any help you can provide!

  • A better way to do concurrent programming

    - by Alex.Davies
    Programming to take advantage of multicore processors is hard. If you let multiple threads access the same memory, bad things happen. To avoid this, you use the lock keyword, but if you use that in the wrong way, your code deadlocks. It's all a nightmare. Luckily, there's a better way - Actors. They're really easy to think about. They're really safe (if you follow a couple of simple rules). And high-performance, type-safe actors are now available for .NET by using this open-source library: http://code.google.com/p/n-act/ Have a look at the site for details. I'll blog with more reasons to use actors and tips and tricks to get the best parallelism from them soon.

  • Source of (programmer) inefficiency

    - by Daniel
    I am interested to gain a better insight about the possible reasons of personal inefficiency as programmers (and only in programming) due to – simply - our own errors (because we are humans – well, almost all of us). I am not interested in how much we are productive or in how many adjustements the customer asks for when the work is done, but where and how each of us spend that part of its time in tasks that are unproductive and there is no one to blame except ourselves. Excluding ego - feeding and / or self – gratification, what I am trying to get (for all of us) is: what are the common issues eating our time; insight on reasons for that issues; identify simple way for us, personally (not delegating actions to other or our organizations), to correct our own problems. Please, do not think in academic terms but aim at the opportunity to compare our daily experiences and understand what are and how we try to fix our personal deficiencies. If you are interested to respond to this post, please: integrate the list if you see something important (or obvious) missing; highlight or name honestly your first issue tellng the way you try to address and solve your issue acting on yourself and yourself only in a sort of "continuous quality improving" My criteria for accepting the answer is: choose the best solution (feasibility and utility) to fix one (or more) of the problems of the list. Of course, selecting an error is not a vote on our skills: maybe we are hyper professional programmers and we lose ten minutes only every year or we are terribly inefficient, losing a couple of days a week: reasons for inefficiency could be really the same - but in a different scale. A possible list: Plain error in the names (variables, functions). Inability to see the obvious in your code. Misreading. Lack of concentration. Trying to use a technology you have not mastered. Errors with data types. Time required to understand your previous code or your documentation. Trying to do something more than requested because you enjoy it Using solutions more complicated than required because you enjoy it. Plain logical errors. Errors due to your fault in communications. Distraction My first personal issue: "Trying to use a technology you do not master." I have to use daily several technologies and I often need to spend significant time correcting code because my assumptions were plainly wrong. Reasons for this: production needs put high pressure and make difficult to find the time to learn. I try to address this reading technical books - as many as I can - even if this actually consumes a lot of time.

  • Backward compatibility with event-sourcing

    - by Tomas Jansson
    How do you stay backward compatible with event-sourcing? Let say you release a version that has one kind of event, let call it X. You know how to handle that event in all the systems that extracts the events from the event source. In a later release you make a change to event X or delete it, how do you stay backward compatible with that? To have a fully functional system you need to be able to handle the old event as the same time as you need to handle the updated version. Or if you delete that event type, then you will be stuck with code that is only there to handle legacy events which in my head can be a little bit messy in the long run.

  • Get to Know a Candidate (12 of 25): Andre Barnett&ndash;Reform 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. Barnett is an American politician and entrepreneur. He is the founder of the information technology (IT) company WiseDome Inc.  Barnett was born in Zanesville, Ohio in 1976. He attended Austin Peay State University and Western Governors University.  A former member of the United States Armed Forces, Barnett served in Sarajevo before being wounded in a helicopter accident.  Following his military service, Barnett became a fitness model in New York. In 2001, he founded WiseDome Incorporated, an IT company that provides information technology and data recovery services. Reform Party of the United States of America (RPUSA), generally known as the Reform Party USA or the Reform Party, is a political party in the United States, founded in 1995 by Ross Perot. Perot said Americans were disillusioned with the state of politics—as being corrupt and unable to deal with vital issues—and desired a viable alternative to the Republican and Democratic Parties. The party has nominated different candidates over the years, such as founder Ross Perot, Pat Buchanan, and Ralph Nader. The party's most significant victory came when Jesse Ventura was elected governor of Minnesota in 1998. Since then, the party has been torn by infighting and disagreements, which it seeks to overcome. The Reform Party platform includes the following: * Maintaining a balanced budget, ensured by passing a Balanced Budget Amendment and changing budgeting practices, and paying down the federal debt * Campaign finance reform, including strict limits on campaign contributions and the outlawing of the Political action committee * Enforcement of existing immigration laws and opposition to illegal immigration * Opposition to free trade agreements like the North American Free Trade Agreement and Central America Free Trade Agreement, and a call for withdrawal from the World Trade Organization * Term limits on U.S. Representatives and Senators * Direct election of the United States President by popular vote * Federal elections held on weekends A noticeable absence from the Reform Party platform has been social issues, including abortion and gay rights. Reform Party representatives had long stated beliefs that their party could bring together people from both sides of these issues, which they consider divisive, to address what they considered to be more vital concerns as expressed in their platform. The idea was to form a large coalition of moderates; that intention was overridden in 2001 by the Buchanan takeover which rewrote the RPUSA Constitution to specifically include platform planks opposed to any form of abortion. The Buchananists, in turn, were overridden by the 2002 Convention which specifically reverted the Constitution to its 1996 version and the party's original stated goals. Barnett has Ballot Access in: FL Learn more about Andre Barnett and Reform Party on Wikipedia.

  • Setting up UPS monitoring

    - by Andrew Heath
    I have acquired a second hand Uninterrupted Power Supply (UPS) that I have refurbished (new battery) and hope to use with my Ubuntu 12.10 system. It's a SOLA 330 with serial out. I have installed NUT Metapackage and NUT Monitor from Software Centre, but am not sure how to go about setting it all up. A Google search brings up several ways of configuring Network UPS Tools (NUT) or HAL-Drivers, however, HAL-Drivers appears to be obsolete and many commands and config files mentioned to edit do not exist in 12.10 or the current version of NUT (most articles are a few years old). One tutorial seemed to work except the Error: no UPS definitions found in ups.conf even though ups.conf has values in it as laid out in the tutorial. How do I go about setting my system to monitor the UPS for a shut down signal? Also, is there a command to determine the UPS is communicating through the serial connection and on what port (to help with setup and configuring, eg. /dev/ttyS0 is mentioned in one of the tutorials I read).

  • Why I'm getting the same result when deleting target?

    - by XNA
    In the following code we use target in the function: moon.mouseEnabled = false; sky0.addChild(moon); addEventListener(MouseEvent.MOUSE_DOWN, onDrag, false, 0, true); addEventListener(MouseEvent.MOUSE_UP, onDrop, false, 0, true); function onDrag(evt:MouseEvent):void { evt.target.addChild(moon); evt.target.startDrag(); } function onDrop(evt:MouseEvent):void { stopDrag(); } But if I rewrite this code without evt.target it still work. So what is the difference, am I going to get errors later in the run time because I didn't put target? If not then why some use target a lot while it works without it. function onDrag(evt:MouseEvent):void { addChild(moon); startDrag(); }
