  • ALPS touchpad stops working after reboot

    - by user58289
    I recently upgraded to 12.04 LTS. My Compaq Presario CQ-40 324la touchpad worked after first restarting after installation. But after restarting a second time, the touchpad is completely disabled, without having changed anything in the system. I've tried solutions but haven't had good results. The applications I've installed (fro "solutions" are: Pointing Devices Synaptiks Dconf-Tools I've also tried updating GRUB, adding this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux") I tried these commands in a terminal. Neither has worked. sudo modprobe -r psmouse sudo modprobe psmouse proto=imps El Touchpad ALPS se desactiva al reiniciar Recién he actualizado a Ubuntu 12.04LTS y a mi parecer ha mejorado mucho con respecto a 11.10... Pero ese no es mi punto ahora. El Touchpad funcionó correctamente luego del primer reinicio después de la instalación. Pero luego de volver a reiniciar, el Touchpad queda totalmente deshabilitado sin haber hecho cambio alguno en el sistema. He probado las soluciones en su mayoría y no he tenido buenos resultados. Las aplicaciones que he instalado (de las "soluciones") son: -Dispositivos apuntadores. -Synaptiks -DConf-Tools Y he intentado también actualizando el grub (añadiéndole una linea así: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux") Intenté en la terminal con el comando: sudo modprobe -r psmouse sudo modprobe psmouse proto=imps Ninguno me ha resultado bien. La laptop es Compaq Presario CQ-40 324la

  • What should a domain object's validation cover?

    - by MarcoR88
    I'm trying to figure out how to do validation of domain objects that need external resources, such as data mappers/dao Firstly here's my code class User { const INVALID_ID = 1; const INVALID_NAME = 2; const INVALID_EMAIL = 4; int getID(); void setID(Int i); string getName(); void setName(String s); string getEmail(); void setEmail(String s); int getErrorsForInsert(); // returns a bitmask for INVALID_* constants int getErrorsForUpdate(); } My worries are about the uniqueness of the email, checking it would require the storage layer. Reading others' code seems that two solutions are equally accepted: both perform the unique validation in data mapper but some set an error state to the DO user.addError(User.INVALID_EMAIL) while others prefer to throw a totally different type of exception that covers only persistence, like: UserStorageException { const INVALID_EMAIL = 1; const INVALID_CITY = 2; } What are the pros and cons of these solutions?

  • How to manage and estimate unstructured requirements received from customers

    - by user20358
    A lot of the times I receive a software system's requirements from our customers in a very unstructured format. It is usually a bunch of "product development" guys from the customer's who come up with these "proposed solutions" to the business problems they have. While they are the experts at the business domain, a lot of the times they don't have the solutions right. This results in multiple versions of the same requirement mixing up of two requirements into one a few versions of the requirement later down the line, the requirements which were combined together get separated out again, each taking with it some of the new additions How do you work with such requirements coming in and sort them out into proper use cases and before development begins? What tools can we use to track a particular requirement's history, from the first time it was conceived till the time it gets crystallized into a proper use case? Estimating work against requirements received in such a fashion is a nightmare which ends up in making mistakes in understanding the requirement correctly and estimating the effort against it correctly. Any tips, tools, tricks to make this activity more manageable? I'm just trying to get some insights from someone more experienced than I am in requirements management and effort estimation.

  • Non-blocking ORM issues

    - by Nikolay Fominyh
    Once I had question on SO, and found that there are no non-blocking ORMs for my favorite framework. I mean ORM with callback support for asynchronous retrieval. The ORM would be supplied with a callback or some such to "activate" when data has been received. Otherwise ORM needs to be split of in a separate thread to guarantee UI responsiveness. I want to create one, but I have some questions that blocking me from starting development: What issues we can meet when developing ORM? Does word "non-blocking" before word "ORM" will dramatically increase complexity of ORM? Why there are not much non-blocking ORMs around? Update: It looks, that I have to improve my question. We have solutions that already allows us to receive data in non-blocking way. And I believe that not all companies that use such solutions - using raw SQL. We want to create more generic solution, that we can reuse in future projects. What difficulties we can meet?

  • Designs for outputting to a spreadsheet

    - by Austin Moore
    I'm working on a project where we are tasked to gather and output various data to a spreadsheet. We are having tons of problems with the file that holds the code to write the spreadsheet. The cell that the data belongs to is hardcoded, so anytime you need to add anything to the middle of the spreadsheet, you have to increment the location for all the fields after that in the code. There are random blank rows, to add padding between sections, and subsections within the sections, so there's no real pattern that we can replicate. Essentially, anytime we have to add or change anything to the spreadsheet it requires a many long and tedious hours. The code is all in this one large file, hacked together overtime in Perl. I've come up with a few OO solutions, but I'm not too familiar with OO programming in Perl and all my attempts at it haven't been great, so I've shied away from it so far. I've suggested we handle this section of the program with a more OO friendly language, but we can't apparently. I've also suggested that we scrap the entire spreadsheet idea, and just move to a webpage, but we can't do that either. We've been working on this project for a few months, and every time we have to change that file, we all dread it. I'm thinking it's time to start some refactoring. However, I don't even know what could make this file easier to work with. The way the output is formatted makes it so that it has to be somewhat hardcoded. I'm wondering if anyone has insight on any design patterns or techniques they have used to tackle a similar problem. I'm open to any ideas. Perl specific answers are welcome, but I am also interested in language-agnostic solutions.

  • WebCenter at Oracle Day Toronto

    - by Lance Shaw
    The Oracle Day event took place in Toronto yesterday at the Hyatt Regency Hotel downtown.  Attendance was excellent and it was standing room only at the keynote sessions.   Anytime the venue has to bring in chairs to handle the overflow crowd, you know there is a lot of interest! This year, WebCenter was featured prominently as part of the Fusion Middleware session track.  What was interesting to see was just how many customers are interested in consolidating and simplifying their existing infrastructure.  So many companies are still struggling with information silos such as file shares, SharePoint Sites and a myriad of departmental or process-centric repositories.  Naturally, these get more and more expensive to manage over time so there is a high level of interest in reducing the size, scope and cost of this infrastructure.  When companies see how they can use Fusion Middleware and related technologies to integrate with WebCenter Content, Imaging and other solutions to centralize content delivery across business applications, they quickly realize that there are significant cost savings to be had. Oracle Day Events are happening all over the world and there is likely going to be one near you.  To check out the full list and to register, visit the Event page here.  It is a great way to not only hear about WebCenter and how it can be used to your advantage, but also a great way to learn about the broader set of related products in the Fusion Middleware portfolio that are available to extend and enhance the power of your particular business solutions. If you cannot make it, or missed the event in your area, be sure to visit our new WebCenter Content page with a variety of informative assets all in one simple location.  It's a new page designed to provide you with easy access to customer stories, videos, whitepapers, webcasts and more.  We hope you find it valuable!

  • Serializing network messages

    - by mtsvetkov
    I am writing a network wrapper around boost::asio and was wondering what is a good and simple way to serialize my messages. I have a message factory which can take care of dispatching the data to the correct builder, but I want to know if there are any established solutions for getting the binary data on the sender side and consequently passing the data for deserialization on the receiver end. Some options I've explored are: passing a pointer to a char[] to the serialize/deserialize functions (for serialize to write to, and deserialize to read from), but it's difficult to enforce buffer size this way; building on that, I decided to have the serialize function return a boost::asio::mutable_buffer, however ownership of the memory gets blurred between multiple classes, as the network wrapper needs to clean up the memory allocated by the message builder. I have also seen solutions involving streambuf's and stringstream's, but manipulating binary data in terms of its string representation is something I want to avoid. Is there some sort of binary stream I can use instead? What I am looking for is a solution (preferrably using boost libs) that lets the message builder dictate the amount of memory allocated during serialization and what that would look like in terms of passing the data around between the wrapper and message factory/message builders. PS. Messages contain almost exclusively built-in types and PODs and form a shallow but wide hierarchy for the sake of going through a factory. Note: a link to examples of using boost::serialization for something like this would be appreciated as I'm having difficulties figuring out the relation between it and buffers.

  • Payables Master Generic Datafix (MGD) Now Checks For Even More EBTax Corruption!!

    - by MargaretW
    The Payables MGD is a vital diagnostic that all R12/12.1 customers need to run regularly to check the data integrity of their Payables system. This script does not make any changes to your system, so it’s risk free and it produces a HTML formatted output showing which data corruption issues have been detected and provides the Doc ID’s that will be needed to fix them. This MGD diagnostic (version 120.92 and above) is even better than it used to be as it now checks for 11 new EBTax corruption signatures that Support was seeing on a consistent basis. These lengthy Service Requests could have been avoided with one run of the MGD which tells you right away if you have data corruption. It’s the first thing our Payables support engineers will have you run when you log an SR so why not be one step ahead? The new EBTax signatures that were included in this latest update to the MGD are pulled from the following common solutions documents: R12 E-Business Tax/Payables Data-Fixes: Cause and action to handle ZX_LINES_SUMMARY_U1 issue Doc ID 1152123.1 EB-Tax Data Corruption Issues & Recommended Solutions Doc ID 1316316.1 The specific issues that are now screened are detailed below: 1. TAXABLE_BASIS_FORMULA and MANUALLY_ENTERED_FLAG mismatch 2. ESTABLISHMENT_ID mismatch 3. TRX_NUMBER mismatch 4. TAX_RATE mismatch 5. Currency Conversion related columns mismatch in Migrated Invoices 6. HISTORICAL_FLAG and RECORD_TYPE_CODE mismatch 7. ADJUSTED_DOC_TRX_LEVEL_TYPE is NULL or APPLIED_FROM_TRX_LEVEL_TYPE is NULL 8. Missing Reversal Tax Distributions For Tax Distributions 9. Tax Lines for discarded or cancelled Transaction Lines are not marked as cancelled 10. Error AP_ERR_TAX_DIST_SYNC 11. AP_UNFROZEN_DIST_EXIST/Unfrozen Tax Distributions exist for this invoice Get Proactive – Check your system for these common EBTax issues and fix the data before it causes a problem.

  • How to switch off? [closed]

    - by Xophmeister
    While I've programmed software for many years, I've only recently started doing so professionally and have noticed a bit of a problematic pattern. I hope this is the best place to pose such a question, as I am interested in others' experiences and solutions... Writing software is, by its nature, a cerebral exercise. When coding for my own sake, I would do so until I was satisfied; even if that meant going all night. Now I'm coding in exchange for goods and services, on projects that are inherently uninteresting to me, I want to 'switch off' when it's time to go home. Maybe you consider that to be a 'bad attitude', but I just don't feel that whatever I'm working on is worth caring about after-hours. Besides, my employer doesn't exactly have the infrastructure required to make out-of-office changes; I can't just clone a repo and even remote login is a PITA. Anyway, the problem I'm experiencing is that, while I'm not particularly overworked or stressed, if I'm faced with a problem, my brain will work on a solution. Generally, it won't give up. Hence I can't switch off and, sometimes, the problem or the solution is significant enough that it disrupts my sleep. While, paradoxically, this doesn't seem to affect my coding ability, it can have a profound impact of the rest of my life. I get increasingly low as I get tired. So far, the best solutions I've found are writing little notes on the matter (and, say, e-mailing them back to my work address) and exercise. Neither of these can switch me off entirely and, as the week progresses, exercise especially becomes untenable due to tiredness. TL;DR How can you stop from being a coding zombie?

  • Impact of Service Oriented Architecture (SOA) on Business and IT Operations

    The impact of Service Oriented Architecture (SOA) on business and IT operations varies from company to company. I think more and more companies are starting to view SOA as just another technology that they can incorporate in an existing or new system. One of the driving factors in using SOA is the reduction in maintenance costs and decrease in the time needed to bring products to market. The reductions in costs, and reduced turnaround time can be directly converted in to increased profitability due to less expenditures that are needed in order to maintain or create new systems. My personal perspective on SOA is that it is great for what it is actually intended to do. SOA allows systems to be distributed across networks or even the world while ensuring enterprise processing consistency, data integrity and preventing code duplication. This being said a lot of preparation and work goes into properly designing and implementing an SOA especially if an enterprise wants to take full advantage of its benefits. Even though SOA has recently gotten a lot of hype about its benefits it does not a perfect fit for all situations. At the end of the day SOA is just another tool in my tool belt that I can pull from to create solutions that meet the business’s needs. Based on current industry trends SOA appears to be a very solid technology to use moving forward, especially as more and more companies shift towards cloud based computing. It is important to remember that SOA is one of many technologies that can be used in creating business solutions and I think more time will be spent in the future evaluating if SOA is the right technology for a solution once the initial hype of SOA has calmed down.

  • SharePoint 2013 Developer Ramp-Up - Part 2

    As stated already yesterday, today I continued with the available course material on Pluralsight. For sure interesting topics in the second part of the series but not the field of operation I'm going to work in later. During the course you get a lot of information about how to create and deploy SharePoint Solutions and hosted SharePoint Apps. Today's resource(s) Apart from some blog articles I watched in the following course today: SharePoint 2013 Developer Ramp-Up - Part 2 - Developing SharePoint Solutions and Apps Not thrilling but still two solid hours to go. Takeaway One of the coolest aspects I figured out today is that SharePoint development can be done easily in JavaScript and C# - just as you like or prefer. It's actually pretty cool to see that you could integrate external JS libraries like datajs, knockout,js and so forth in order to implement your solution. And that you should be very familiar with Microsoft PowerShell. Not only to simplify some repetitive work but also to do be able to get things going in SharePoint. Having a decent background knowledge in Linux, I find this pretty amusing and remember the initial baby steps when PowerShell was introduced some years back (Note: German language). The outcry as well as the hype was too funny. Honestly, I have kind of mixed feelings about today's progress. Surely, there was interesting information about developing extensions directly for and in SharePoint... Hm, I'll leave that one for now and probably it might be helpful someday.

  • What is the best book for the preparation of MCPD Exam 70-564 (Designing and Developing ASP.NET 3.5 Applications)?

    - by Steve Johnson
    Hi all, I have seen a couple of questions like this one and scanned through the answers but somehow the replies were not satisfactory or practical. So i wondered maybe people who have gone through it and may suggest a better approach for the preparation of this exam. Goal: My goal is actually NOT merely to pass that exam. I intend to actually master the skill. I have been into asp.net web development for approximately 1.5 years and I want to study something that really improves "Design and Development Skills" in Web Development in general and asp.net to be specific which i can put to use and build upon that. Please suggest a book that teaches professional Asp.Net design and development skills and approaches to quality development by taking through practice design scenarios and their solutions and through various case studies that involve design problems and their implemented solutions. Edit: I have found the Micorosoft training kits to be fairly interesting and helpful as these tend to increase knowledge. I have utilized a lot of things after getting a good explanation of things from the training kits. However, as far as Microsoft Training Kit for 70-564 is concerned, there are not a lot of good reviews about it. What i have read and searched on the net , the reviews on amazon and various forums, stack-exchange and experts-exchange, were more inclined to the conclusion that "Microsoft Training Kit for Exam 70-564 is not good. Its is not good as compared to other kits from Microsoft, like as compared to the training kit of Exam 70-562 or others." So i was looking for a proper book containing examples from practical world scenarios and case studies from which i can not only learn but also master the skills before wasting money of Microsoft Training Kit for Exam 70-564. Waiting for experts to provide a suitable advice.

  • Cheap ways to do scaling ops in shader?

    - by Nick Wiggill
    I've got an extensive world terrain that uses vec3 for the vertex position attribute. That's good, because the terrain has endless gradations due to the use of floating point. But I'm thinking about how to reduce the amount of data uploaded to the GPU. For my terrain, which uses discrete / grid-based vertex positions in x and z, it's pretty clear that I can replace my vec3s (floats, really) with shorts, halving the per-vertex position attribute cost from 12 bytes each to 6 bytes. Considering I've got little enough other vertex data, and an enormous amount of terrain data to push into the world, it's a major gain. Currently in my code, one unit in GLSL shaders is equal to 1m in the world. I like that scale. If I move over to using shorts, though, I won't be able to use the same scale, as I would then have a very blocky world where every step in height is an entire metre. So I see these potential solutions to scale the positional data correctly once it arrives at the vertex shader stage: Use 10:1 scaling, i.e. 1 short unit = 1 decimetre in CPU-side code. Do a division by 10 in the vertex shader to scale incoming decimetre values back to metres. Arbirary (non-PoT) divisions tend to be slow, however. Use (some-power-of-two):1 scaling (eg. 8:1), which enables the use of a bitshift (eg. val >> 3) to do the division... not sure how performant this is in shaders, though. Not as intuitive to read values, but possibly quite a bit faster than div by a non-PoT value. Use a texture as lookup table. I've heard that this is really fast. Or whatever solutions others can offer to achieve the same results -- minimal vertex data with sensible scaling.

    If you follow my updates on Twitter or on the OTN ArchBeat page on Facebook you have probably noticed that I'm a regular reader of Joe McKendrick's SOA blog on ZDNet. Usually I'm content to simply share a link on my social networks when I find one of McKendrick's posts interesting. But with a recent post, In the cloud era, let's start calling IT what it is: 'Innovation Team', McKendrick hit on a point that warrants more than a quick link: "IT is no longer just a department full of people who code, build and maintain systems. IT is the business partner that plans and strategizes what types of technology solutions the business needs to move forward." Of course, what McKendrick is describing is an increased focus on architecture. Assuming that McKendrick's assessment is correct — and I do — that expanding focus, from coding, building, and maintaining systems to planning and strategizing technology solutions that serve the business, isn't limited to the organizational level. The individual roles within the IT organization will also have to shift to a more broadly architectural mindset. McKendrick's post references Dr. Irving Wladawsky-Berger's assessment of cloud computing as a critical "third model" of computing to emerge in the 50-year history of Information Technology. As computing itself evolves, the underlying roles that make computing possible must evolve accordingly. That evolution will be defined by an increased focus on architecture.

  • Dual boot problem with ubuntu 12.04 and Vista

    - by vendella dahlahdoo
    Greetings from New Zealand. I have installed Microsoft Windows Vista and then installed Ubuntu 12.04 on my refurbished Compaq nx8220 laptop. I get the following infamous head hurting prompt continually. error: no such partition. grub rescue> Have tried most of the common recommended solutions. Live-CD then install Boot-Repair through the Terminal didn't work. It repaired all the linux stuff when restoring grub and then can't boot into Windows Vista. When I use Boot-Repair to fix the MBR, then I can't boot into Ubuntu. Tried installing BCD 2.1 in Vista and tried all the options one after another in BCD. Still no Ubuntu when selected through the options menu from BCD on restart/reboot. I have tried the boot repair option on the Ubuntu server CD-ROM, tried installing earlier versions of Ubuntu 11.04, 11.10, and Ubuntu server 11.10 and 12.04. Still the same result. I tried deleting the Ubuntu partitions through Vista a number of times and reinstalling Ubuntu. I have been trying and retrying all the options in Boot-Repair in different combinations for the past week and a half. I have tried at least 10 times installing and reinstalling Ubuntu. I really love Ubuntu and believe I have exhausted most of the recommended solutions and have spent too much time on this. Its driving me nuts!! please can someone help, I have finally given up (sigh). The following are some outputs from Boot-Repair from my last attempts. http://paste.ubuntu.com/1019227 http://paste.ubuntu.com/1019264 I was only allowed to post two links being a newbie. The only thing left for me to do is the flying Samoan dropkick laptop trick. Thanks in advance. Francis.
