Triple monitor setup in linux

- by Brendan Abel

I'm hoping there are some xorg gurus out there. I'm trying to get a three monitor setup working in linux. I have 2 lcd monitors and a tv, all different resolutions. I'm using 2 video cards; a 9800 GTX and 7900Gt. I've seen a lot of different posts about people trying to make this work, and in every case, they either gave up, or Xinerama magically solved all their problems. Basically, my main problem is that I cannot get Xinerama to work. Every time I turn it on in the options, my machine gets stuck in a neverending boot cycle. If I disable Xinerama, I just have three Xorg screens, but I can't drag windows from one to the other. I can get the 2 lcds on Twinview, and the tv on a separate Xorg screen no problem. But I don't really like this solution. I'd rather have them all on separate screens and stitch them together with Xinerama. Has anyone done this? Here's my xorg.conf for reference. p.s. This took me all of 30 seconds to set up in Windows XP! p.s.s. I've seen somewhere that maybe randr can solve my problems? But I'm not quite sure how?

How should we serve files in a small bioinformatics cluster?

- by cespinoza

We have a small cluster of six ubuntu servers. We run bioinformatics analyses on these clusters. Each analysis takes about 24 hours to complete, each core i7 server can handle 2 at a time, takes as input about 5GB data and outputs about 10-25GB of data. We run dozens of these a week. The software is a hodgepodge of custom perl scripts and 3rd party sequence alignment software written in C/C++. Currently, files are served from two of the compute nodes (yes, we're using compute nodes as file servers)-- each node has 5 1TB sata drives mounted separately (no raid) and is pooled via glusterfs 2.0.1. They each have as 3 bonded intel ethernet pci gigabit ethernet cards, attached to a d-link DGS-1224T switch ($300 24 port consumer-level). We are not currently using jumbo frames (not sure why, actually). The two file-serving compute nodes are then mirrored via glusterfs. Each of the four other nodes mounts the files via glusterfs. The files are all large (4gb+), and are stored as bare files (no database/etc) if that matters. As you can imagine, this is a bit of a mess that grew organically without forethought and we want to improve it now that we're running out of space. Our analyses are I/O intensive and it is a bottle neck-- we're only getting 140mB/sec between the two fileservers, maybe 50mb/sec from the clients (which only have single NICs). We have a flexible budget which I can probably get up $5k or so. How should we spend our budget? We need at least 10TB of storage fast enough to serve all nodes. How fast/big does the cpu/memory of such a file server have to be? Should we use NFS, ATA over Ethernet, iSCSI, Glusterfs, or something else? Should we buy two or more servers and create some sort of storage cluster, or is 1 server enough for such a small number of nodes? Should we invest in faster NICs (say, PCI-express cards with multiple connectors)? The switch? Should we use raid, if so, hardware or software? and which raid (5, 6, 10, etc)? Any ideas appreciated. We're biologists, not IT gurus.

Building Great-Looking, Usable Apps: A two-day workshop applying Oracle’s best UX practices in ADF

- by mvaughan

By Misha Vaughan, Oracle Applications User ExperienceI have been with Oracle for more than 12 years. It is a company that has granted me extraordinary creative freedom to help deliver compelling experiences for customers.I am beyond proud to talk about one of the experiences we just took for a test drive. Recently, we delivered a first-of-its-kind, three-team collaboration, train-the-trainer event in Reading, U.K., on building great-looking, usable apps based on Oracle Fusion Applications -- using the ADF tool kit. A new kind of workshopKevin Li, Platform Product Director, asked the Oracle Applications User Experience VP, Jeremy Ashley, if the team had anything to help partners and customers build applications that looked like Fusion. He was receiving this request from European partners and customers.Some quick conversations ensued, and the idea for the workshop was born: We would conduct an experiment. We would work with feedback from the key Platform Technology Solutions (PTS) trainers under Andre Pavanello, Director, Platform Technology Solutions, in Europe, Middle East, and Africa. We would partner with the ADF team lead by Grant Ronald, Director of Product Management, title> and leverage the Applications UX expertise in Ashley’s team.The goal: Create a pilot workshop that in two days would explain to an ADF developer how to leverage the next-generation user experience best-practices developed for Fusion Apps. Why? Customers who need integrations with Oracle Fusion Applications, who are looking for custom applications that need to co-exist with Fusion, or who quite simply want a next-generation design for a custom app, need their solutions to reflect the next-generation research and design.Building an event for an ADF developerThe biggest hurdle was figuring out where to start. How far into user experience country do you take an ADF developer? How far into ADF do you need to go if you are a UX professional?After some time in the UX kitchen, the workshop recipe looked like this: Mix equal parts: Fusion user experience design principles and functional design patterns The art and science behind UX How to wireframe designs that you can build in Fusion How to translate those designs into an ADF application Ultan O’Broin, Director of Global User Experience, explaining the trouble ticket wireframe design exerciseLynn Munsinger, Senior Group Product Manager, explaining the follow-on trouble ticket ADF coding exercise For spice, add:• Debra Lilley, Fujitsu and ACE director, showcasing some of the latest ADF design work in the new face of Fusion Applications • Partner show-and-tell of example apps they have built with FMW and ADF that are dynamic, beautiful, and interactive.Debra Lilley, Oracle ACE Director and Fujitsu Fusion Champion on the new face of Fusion built with ADF and Fusion extensibility with composers as a window into “the possible”?The taste testThis first go-round of the workshop was aimed squarely at ADF developers and partners. We were privileged to have participation and feedback from:• Sten Vesterli, Scott/Tiger S. A., Denmark• John Sim, Fishbowl Solutions, UK• Josef Huber, Primus Delphi Group, Munich• Thaddaus Weindl, Primus Delphi, Group , Munich• Praveen Pillalamarri, EiS Technologies, Bangalore• Balaji Kamepalli, EiS Technologies, Bangalore• Plinio Arbizu, Services & Processes Solutions S. A., Mexico• Yannick Ongena, infoMENTUM, UK• Jakub Ciszek, infoMENTUM, UK• Mauro Flores, infoMENTUM, UK• Matteo Formica, infoMENTUM, UKRichard Bingham, Oracle, Mauro Flores and Matteo Formica, infoMENTUMWhy is this so exciting? Oracle has invested heavily in the research and development of the Oracle Fusion Applications user experience. This investment has been and continues to be applied across the product lines. Now, we finally get to teach customers and partners how to take advantage of this investment for custom solutions.This event was a pilot to test-drive the content, as well as a train-the-trainer event that our EMEA colleagues will be using with partners who want to build with Fusion Apps design patterns.What did attendees think?"I liked most the science stuff, like eye-tracking, design patterns and best-practice (color, contrast),” Josef Huber said. “It was a very good introduction to UI design, and most developers and project managers are very bad in that. So this course would be good for all developers and even project managers." Team Anonymous: John Sim, Fishbowl Solutions, Flavius Sana, Oracle, Josef Huber, infoMENTUM, Mireille Duroussaud, Oracle. Winners of the wireframing design exercise. Sten Vesterli, of Scott/Tiger, said he attended to learn techniques he could use in his own projects. He wants to ensure that his applications better meet the needs of his users, and he said sessions during the workshop on user interface design and wireframing were most useful to him. “Go to this event to learn the art and science of good user interfaces from people who really know how to do it,” he said.Sten Vesterli, Scott/Tiger, Angelo Santagata, Oracle Plinio Arbizu said the workshop fulfilled his goals, thanks to the recommendations given in how to design user interfaces to facilitate the adoption of applications among the final users. “The workshop combined these recommendations with an exercise that improved the technical comprehension, permitting the usage of JDeveloper to set forth our solutions,” he said. He added: “The first session that I really enjoyed was the five Fusion design principles. It was incredible to discover how these simple principles were included in an inherit manner in Fusion Applications, and I had been using many of them applying only ADF components. Another topic that I enjoyed a lot was the eight recommendations about the visual design of UIs. The issues that were raised in that lesson are unknown to the developers and of great value to achieve an attractive presentation layer to the end users. Participate in this workshop, and include these usability features in your projects and in this manner not only to facilitate and improve the user productivity, but also to distinguish you as a professional who takes advantage fully of the functionalities offered by Oracle technology. Praveen Pillalamarri came to the workshop to learn about the difficulties faced in UI and UX development, and how this can be resolved with the help of ADF. He also appreciated the opportunity to talk with other individuals who came to the workshop. Pillalmarri said, “The way we looked at things in terms of work and projects were sharpened. UI and UX design knowledge shared by you was quite interesting, especially the minute things which we ignored in the UI or UX design.” Plinio Arbizu, Services & Processes Solutions S. A., Richard Bingham, Oracle, Balaji Kamepalli, & Praveen Pillalamarri, EiS TechnologiesReady to spread the wordIn EMEA, Oracle customers and partners have access to three world-class trainers via Platform Technology Solutions: Mireille Duroussaud, Flavius Sana, and Angelo Santagata. Contact Andre Pavanello if you like to experience this workshop firsthand, or you have customers or partners who would benefit from the training.We are looking to bring the event to the U.S. in spring 2013. If you have interest in this kind of a workshop, leave a comment below. For those who want to follow the action, join the ADF Enterprise Methodology Group run by Oracle’s Chris Muir.

Flashing your Windows Phone Dummies

- by Martin Hinshelwood

The rate at which vendors release new updates for the HD2 is ridiculously slow. You have to wait for Microsoft to release the new OS, then you wait for HTC to build it into a ROM, and then you have to wait up to 6 months for your operator to badly customise it for their network. Once Windows Phone 7 is released this problem should go away as Microsoft is likely to be able to update the phone over the air, but what do we do until then? I want Windows Mobile 6.5.5 now! I’m an early adopter. If there is a new version of something then that’s the version I want. As long as you accept that you are using something on a “let the early adopter beware” and accept that there may be bugs, sometimes serious crippling bugs the go for it. Note that I won't be responsible if you end up bricking your phone, unlocking or flashing your radio or ROM can be risky. If you follow the instructions then you should be fine, I've flashed my phones (SPV, M300, M1000, M2000, M3100, TyTN, TyTN 2, HD2) hundreds of times without any problems! I have been using Windows Mobile 6.5.5 before it was called 6.5.5 and for long enough that I don’t even remember when I first started using it. I was using it on my HTC TyTN 2 before I got an HD2 a couple of months before Christmas, and the first custom ROM’s for the HD2 were a couple of months after that. I always update to the latest ROM that I like, and occasionally I go back to the stock ROM’s to have a look see, but I am always disappointed. Terms: Soft Reset: Same as pulling out the battery, but is like a reboot for your phone Hard Reset: Reinstalls the Operating system from the Image that is stored on it ROM: This is Image that is loaded onto your phone and it is used to reinstall your phone whenever you do a “hard reset”. Stock ROM: A ROM from the original vendor… So HTC Cook a ROM: Referring to Cooking a ROM is the process a ROM developer goes through to take all of the parts (OS, Drivers and Applications) that make up a running phone and compiling them into a ROM. ROM Kitchen: A place where you get an SDK and all the component parts of the phone: OD, Drivers and Application. There are usually lots of Tools for making it easier to compile and build the image. Flashing: The process of updating one of the layers of your phone with a new layer Bricked: This is what happens when flashing goes wrong. Your phone is now good for only one thing… stopping paper blowing away in a windy place. You can “cook” you own ROM using one of the many good “ROM Kitchens” or you can use a ROM built and tested by someone else. I have cooked my own ROM before, and while the tutorials are good, it is a lot of hassle. You can only Flash new ROM’s that are specifically for your phone only so find a ROM for your phone and XDA Developers is the best place to look. It has a forum based structure and you can find your phone quite easily. XDA Developer Forum Installing a new ROM does have its risks. In the past there have been stories about phones being “bricked” but I have not heard of a bricked phone for quite some years. if you follow the instructions carefully you should not have any problems. note: Most of the tools are written by people for whom English is not their first language to you will need concentrate hard to understand some of the instructions. Have you ever read a manual that was just literally translated from another language? Enough said… There are a number of layers on your phone that you will need to know about: SPL: This is the lowest level, like a BIOS on a PC and is the Operating Systems gateway to the hardware Radio: I think of this as the hardware drivers, and you will need a different Radio for CDMA than GSM networks ROM: This is like your Windows CD, but it is stored internally to the Phone. Flashing your phone consists of replacing one Image with another and then wiping your phone and automatically reinstall from the Image. Sometimes when you download an Image wither it is for a Radio or for ROM you only get a file called *.nbh. What do you do with this? Well you need an RUU application to push that Image to your phone. The RUU’s are different per phone, but there is a CustomRUU for the HD2 that will update your phone with any *.nbh placed in the same directory. Download and Instructions for CustomRUU #1 Flash HardSPL An SPL is kind of like a BIOS, and the default one has checks to make sure that you are only installing a signed ROM. This would prevent you from installing one that comes from any other source but the vendor. NOTE: Installing a HARD SPL invalidates your warranty so remember to Flash your phone with a “stock” vendor ROM before trying to send your phone in for repairs. Is the warranty reinstated when you go back to a stock ROM? I don’t know… Updating your SPL to a HardSPL effectively unlocks your phone so you can install anything you like. I would recommend the HardSPL2. Download and Instructions for HardSPL2 #2 Task29 One of the problems that has been seen on the HD2 when flashing new ROM’s is that things are left over from the old ROM. For a while the recommendation was to Flash a stock ROM first, but some clever cookies have come up with “Task29” which formats your phone first. After running this your phone will be blank and will only boot to the white HTC logo and no further. You should follow the instructions and reboot (remove battery) and hold down the “volume down” button while turning you HD2 on to enter the bootloader. From here you can run CustomRUU once the USB message appears. Download and Instructions for Task29 #2 Flash Radio You may need to play around with this one, there is no good and bad version and the latest is not always the best. You know that annoying thing when you hit “end call” on your phone and nothing happens? Well that's down to the Radio. Get this version right for you and you may even be able to make calls. From a Windows Mobile as well Download There are no instructions here, but they are the same as th ROM, but you use this *.nbh file. #3 Flash ROM If you have gotten this far then you are probably a pro by now Just download the latest ROM below and Flash to your phone. I have been really impressed by the Artemis line of ROM’s but it is no way the only choice. I like this one as the developer builds them as close to the stock ROM as possible while updating to the latest of everything. Download and Instructions for Artemis HD2 vXX Conclusion While updating your ROM is not for the faint hearted it provides more options than the Stock ROM’s and quicker feature updates than waiting… Technorati Tags: WM6

Master Data

- by david.butler(at)oracle.com

Let's take a deeper look at what we mean when we talk about 'Master' data. In its most general sense, master data is data that exists in more than one operational application. These are the applications that automate business processes. These applications require significant amounts of data to function correctly. This includes data about the objects that are involved in transactions, as well as the transaction data itself. For example, when a customer buys a product, the transaction is managed by a sales application. The objects of the transaction are the Customer and the Product. The transactional data is the time, place, price, discount, payment methods, etc. used at the point of sale. Many thousands of transactional data attributes are needed within the application. These important data elements are local to the applications and have no bearing on other applications. Harmonization and synchronization across applications is not necessary. The Customer and Product objects of the transaction also have a large number of attributes. Customer for example, includes hierarchies, hierarchical and matrixed relationships, contacts, classifications, preferences, accounts, identifiers, profiles, and addresses galore for 'ship to', 'mail to'; 'service at'; etc. Dozens of attributes exist for individuals, hundreds for organizations, and thousands for products. This data has meaning beyond any particular application. It exists in many applications and drives the vital cross application enterprise business processes. These are the processes that define and differentiate the organization. At every decision point, information about the objects of the process determines the direction of the process flow. This is the nature of the data that exists in more than one application, and this is why we call it 'master data'. Let me elaborate. Parties Oracle has developed a party schema to model all participants in your daily business operations. It models people, organizations, groups, customers, contacts, employees, and suppliers. It models their accounts, locations, classifications, and preferences. And most importantly, it models the vast array of hierarchical and matrixed relationships that exist between all the participants in your real world operations. The model logically separates people and organizations from their relationships and accounts. This separation creates flexibility unmatched in the industry and accounts for the fact that the Oracle schema for Customers, Suppliers, and Accounts is a true superset of the wide variety of commercial and homegrown customer models in existence. Sites Sites are places where business is conducted. They can be addresses, clusters such as retail malls, locations within a cluster, floors within a building, places where meters are located, rooms on floors, etc. Fully understanding all attributes of a site is key to many business processes. Attributes such as 'noise abatement policy' at a point of delivery, or the size of an oven in a business kitchen drive day-to-day activities such as delivery schedules or food promotions. Typically this kind of data is siloed in departments and scattered across applications and spreadsheets. This leads to conflicting information and poor operational efficiencies. Oracle's Global Single Schema can hold all site attributes in one place and enables a single version of authoritative site information across the enterprise. Products and Services The Oracle Global Single Schema also includes a number of entities that define the products and services a company creates and offers for sale. Key entities include Items organized into Catalogs and Price Lists. The Catalog structures provide for the ability to capture different views of a product such as engineering, manufacturing, and service which are based on a unified product model. As a result, designers, manufacturing engineers, purchasers and partners can work simultaneously on a common product definition. The Catalog schema allows for unlimited attributes, combines them into meaningful groups, and maps them to catalog categories to track these different types of information. The model also maps an unlimited number of functional structures for each item. For example, multiple Bills of Material (BOMs) can be constructed representing requirements BOM, features BOM, and packaging BOM for an item. The Catalog model also supports hierarchical information about each item and all standard Global Data Synchronization attributes. Business Processes Utilizing Linked Data Entities Each business entity codified into a centralized master data environment significantly improves the efficiency of the automated business processes that use the consolidated data. When all the key business entities used by an organization's process are so consolidated, the advantages are multiplied. The primary reason for business process breakdowns (i.e. data errors across application boundaries) is eliminated. All processes are positively impacted and business process automation is itself automated. I like to use the "Call to Resolution" business process as an example to help illustrate this important point. It involves call center applications, service applications, RMA applications, transportation applications, inventory applications, etc. Customer, Site, Product and Supplier master data must all be correct and consistent across these applications. What's more, the data relationships between customer and product, and product and suppliers must be right. This is the minimum quality needed to insure the business process flows without error. But that is not the end of the story. Critical master data attributes such as customer loyalty, profitability, credit worthiness, and propensity to buy can optimize the call center point of contact component of the process. Critical product information such as alternative parts or equivalent products can optimize the resolution selected by the process. A comprehensive understanding of the 'service at' location can help insure multiple trips are avoided in the process. Full supplier information on reliability, delivery delays, and potential alternates can prevent supplier exceptions and play a significant role in optimizing the process. In other words, these master data attributes enable the optimization of the "Call to Resolution" enterprise business process. Master data supports and guides business process flows. Thus the phrase 'Master Data' is indeed appropriate. MDM is the software that houses, manages, and governs the master data that resides in all applications and controls the enterprise business processes. A complete master data solution takes a data model that holds fully attributed master data entities and their inter-relationships. Oracle has this model. Oracle, with its deep understanding of application data is the logical choice for managing all your master data within the enterprise whether or not your organization actually runs any Oracle Applications.

Gartner PCC Follow-up: Interview with Chaeny Emanavin, Usability Lead - Office of Information Develo

- by [email protected]

Last week at the Gartner Portals, Content and Collaboration conference in Baltimore, Chaeny and I co-presented on Oracle Enterprise 2.0 and BIA's Citizen Portal. Chaeny's presentation about the BIA solution was very well received and I wanted to do a follow-up interview with Chaeny to discuss more details about their solution and its Enterprise 2.0 features. Ajay: What were the main objectives for the BIA Citizen Portal? Chaeny: The BIA Citizen Portal is designed to provide all the services of the Bureau of Indian Affairs to the community of 564 federally recognized tribes that include over 1.9 million American Indians and Alaska Natives. The BIA provides the same breadth of services that the entire U.S. Federal Government provides in one small Bureau. So, we needed a solution that was flexible enough to handle content ranging from law enforcement to housing to education. Key objectives for external users was to use the Web as a communications channel and keep them informed on what services are available. We also wanted to build an internal web presence and community for BIA's 5000 employees to ensure that they update their content, leverage internal experts and create single sources of truth for key policy documents. Ajay: How is the project being implemented? Chaeny: We are using a phased approach. In phases 1 & 2, interim internal and external sites were built to ensure usability and functional requirements are being met. In Phases 3 & 4, we built out a modern internal and external presence using Oracle WebCenter Suite and Oracle Universal Content Management (UCM), including enabling delegated content management for our internal business units. Phase 4 was completed in January 2010. Phase 5 will add deeper Enterprise 2.0 collaboration capabilities to the solution. Ajay: Are you integrating any existing sites into the new solution? Chaeny: Yes, we have a SharePoint implementation that we are using for document management. We needed more precise functionality however. We found that SharePoint would let individual administrators of a SharePoint site actually create new sites. In a 3 months span, we had over 200 new sites created and most were not being used. So, we had an enormous sprawl problem. Our requirements mandated increased governance and more granular control over the creation of sites and flexible user access to content. In SharePoint this required custom code and was very time-intensive which was unfeasible given our tight deadlines. We are piloting Oracle WebCenter Spaces as our collaboration solution to mitigate these issues. However, we must integrate our existing SharePoint investment which we can do easily by using the SharePoint connectors available in Oracle WebCenter and UCM. Ajay: What were the key design parameters for your solution? Chaeny: We wanted everything driven by standards and policies. We created a cross-functional steering group called the Indian Affairs Web Council to codify policies that were baked into the system. Other key design areas were focused on security/governance, self-service content management, ease of use, integration with legacy applications and seamless single sign-on. We are using Dublin Core as our metadata standard. We also are using Java, APEX, and ADF as our development standards. Ajay: Why was it important to standardize on a platform? Chaeny: We initially looked at best-of-breed solutions, but we faced a lot of issues getting the different solutions to work together. Going with an integrated solution was more economical, easier to learn and faster to deliver the solution. Ajay: What type of legacy applications are you integrating into the portal? Chaeny: Initially we are starting with administrative apps such as people directory and user admin and then we will integrate HR and Financial applications among others. Ajay: Can you describe some of the E20 collaboration features you are putting into the solution? Chaeny: We are adding Enterprise 2.0 using Oracle WebCenter Spaces to deliver different collaboration tools such as wikis, blogs and discussion forums. Wikis to create rapid, ad hoc monthly roll-up reports; discussion forums to provide context-specific help; blogs to capture tacit organization knowledge from experts, identify gurus and turn tacit knowledge into explicit knowledge. Ajay: Are you doing anything specifically to spur adoption and usage? Chaeny: Yes, we did several things that I think helped us ramp quickly. First, we met our commitments for the new system launch date and also provided extra resources for a customer support "hotline" during the launch period. Prior to launch, we did exhaustive usability studies to capture user requirements around functionality, navigation and other key interaction areas. We also created extensive training programs so that the content managers in each business unit were comfortable using the content management tools and knew the best practices for usage. Finally, to launch the Enterprise 2.0 collaboration capabilities, we are working with a pilot group from the Division of Forestry and Wildland Fire Management of BIA. This group of people in the past have been willing early adopters and they have a strong business need to collaborate with many agencies both internal and external across State, County and other Federal jurisdictions. Their feedback is key to helping us launch Enterprise 2.0 successfully in our broader organization. Ajay: What were the biggest benefits to internal BIA employees and to the external community of users? Chaeny: For our employees, the new Enterprise 2.0-based solution will make it easier to find information; enhance employee productivity by embedding standard business processes into the system and create more of a community by creating connections with experts via social collaboration to ultimately provide better services more quickly. For the external American Indian and Alaska Native communities, we have a better relationship with the users and the new site has improved BIA's perception as a more responsive and customer-centric organization.

Edit ePub eBooks with Your Favorite HTML Editor

- by Matthew Guay

ePub eBooks are increasingly popular today, but often they’ve been made by converting other file formats. Here’s how you can edit ePub books to remove irregularities and make them better for reading on your devices. ePub’s are actually a zip file containing images, XHTML files with your text, and more with the .epub extension. You can make them better by editing the XHTML files directly. Code gurus can edit the code directly, but even if you’ve never edited HTML, you can still quickly make changes with a WYSIWYG editor. Extract the Files from your ePub eBook As mentioned before, ePub files are actually renamed zip files. So first let’s get all of the files in your ePub eBook accessible. Find an eBook you want to edit and then change the file extension to .zip. If you don’t see the file extensions, click Organize in the menu bar and select Folder and search options. Select the View tab, and then uncheck the box beside Hide extensions for known file types. Click Ok, and then change the file type as above. Windows will warn you about changing the file type; click Yes to proceed. Now you can browse the files of the ePub file. Notice that it contains mostly HTML or XHTML files and images. Click Extract all files to save them all in a folder so you can easily edit them. Alternately, you can open the ePub file directly in your favorite file archival program such as 7-zip. Browse to the location of your ePub file, double-click it, and it’ll automatically open even if you don’t change the file extension to zip. Now you can extract the folder, or extract individual files as before. Edit Your eBook in KompoZer The actual ebook contents are stored in HTML or XHTML files. These may be stored on the top folder of you ePub file’s directory, or they may be stored in \OEBPS\text in the file. To change the contents of your eBook, you’ll want to edit these files. Often there may be separate files for each chapter, so you may have to use trial and error to find the one you need to edit. You could edit them by hand in Windows using Notepad if you don’t have an HTML editor installed. A better option would be to use an HTML editor. Here we’ll use the free KompoZer program to edit the files just like we’d edit a document in Word. Download KompoZer (link below), and unzip the files. Then open the new folder and launch kompozer.exe; you don’t even need to install it. In fact, you could even store KompoZer on a flash drive so you could edit HTML files from any computer. In KompoZer, open the HTML or XHTML file from your eBook that you want to edit. Now you can edit the file just like you would edit a document in Word. Remove extra and unneeded text, make titles stand out, correct misspellings … anything you want! This is especially helpful if your ePub file was created by converting a PDF as these often have many small errors. Or, if you’d rather edit the code itself, select the Source tab and edit as you wish. When you’re done making the changes, make sure to save the file in the same location with the same file name. Recreate Your Edited ePub eBook Once you’ve made all the changes you wanted, it’s time to turn this folder of files back into ePub. Make sure you change the name of the folder if it still has the same name as the original ePub or zip file so you don’t mix them up or have trouble with overwriting the old files. Zip the folder using Windows Explorer or your favorite archival utility. If you are using another archival program, make sure to compress it as a zip folder; other compression methods will render the ePub unreadable by your eReader app. Now change the file extension again, this time back to .epub. Now you can read your eBook with your changes in your favorite reader program or app on your mobile device. Conclusion Whether you need to remove an odd, misplaced character or need to do fine editing, using an HTML editor is a great way to make your ePub eBooks look just like you want. Also, with an editor like KompoZer it’s not even difficult.

“My life at Oracle”

- by cristian.condurache(at)oracle.com

Hello everybody! My name is Eva and I currently work in Oracle Italy as Sales Programs Manager for the Technology Sales organization. Since 2009, I also proudly represent the Oracle Education Foundation within my country as the Ambassador for Italy. My career path in this amazing company began 5 years ago as a fresh graduate: after various years studying abroad, in Germany and Ireland mainly, I was looking for a valuable and concrete opportunity which could fulfill my energetic spirit. I wanted to develop myself inside a stimulating and “fast” business environment.. and here came Oracle and I really couldn’t ask for anything better! THE PARTNER EXPERIENCE The first department I had the chance to work into was the Alliances and Channels organization, where I had the opportunity to join a brilliant team of great and visionary guys. I began having the responsibility to analyze and rationalize the portfolio of Oracle business partners and to identify potential cross-area solutions, which had to be highlighted both on the local market and internationally: this ended up with the implementation of the “Partner Community” model, a business environment of selected Oracle partners, specialized on the different technology focus areas. This new concept was then recognized as an EMEA Best Practice and replicated internationally. Having the opportunity to strengthen day after day strategic relationships with several business partners and study the market positioning of their technology solutions, I was given the role to develop the “Oracle Partner Network Innovation Award” in Italy: the EMEA competition encouraging and rewarding proven and successful technology innovations, creating high value for our common customers and generating new business potential. Several Italian partner solutions won different prizes and I decided that it was worth collecting all those valuable projects, winners and short-listed, inside two specific books in order also to provide them an international market visibility: OPN Innovation Award Booklet 2007 and OPN Innovation Award Booklet 2008 Inside the Alliances and Channels department I really had the opportunity to do amazing things, like for example working side-by-side with one of the most exceptional teams in Oracle I have ever worked with: the EMEA Recruitment Team. Together, in fact, we conceived a brand new business initiative for our partners, called “Oracle Campus Joint Program”. This program was awarded as an EMEA Best Practice and acknowledged by both Italian public institutions and press media. Italy is currently running its 5th edition. Briefly, the “Oracle Campus Joint Program” aims at facing the growing issue of lack of technology competences and skills on the market. By identifying a specific technology area and developing an intensive 4-6 week Oracle University training course and by collaborating with important academic institutes, international “gurus” and professionals, our business partners are able to benefit from a pool of brilliant top talented young consultants and offer them a significant career opportunity. BUSINESS BUT NOT ONLY: THE NO-PROFIT EXPERIENCE OF ORACLE Currently my mission in Oracle is to continue driving the implementation of strategic business development and sales programs for the entire Oracle Technology stack, involving both partners and the end-customers. But as a completely distinguished role from the day-today business, I’m also honored to represent in Italy the charity global organization founded by Oracle - the Oracle Education Foundation - and drive its corporate citizenship and marketing programs. Oracle Education Foundation is an independent charitable organization funded by Oracle and is dedicated to helping students develop 21st century skills through project learning and the use of technology. It provides “ThinkQuest” as a free program to primary and secondary (K12) schools. Just some significant numbers: today 548,000 students/teachers in 47 countries use ThinkQuest and the Oracle Education Foundation partners with 40+ no-profit or government organizations globally. ABOUT MYSELF AND MY INTERESTS About myself…I’m very enthusiastic and positive, trying always to transform difficult issues in challenging opportunities. My day usually begins very early in the morning with running, swimming or when I need to collect some “zen” energies with a yoga session or better with a long walk with my dog. I definitely love animals and generally speaking I’m very keen on environmental issues and try, as much as I can, to carry out a healthy and “planet respectful” lifestyle. My thirst for knowledge pushed me some time ago to begin a new personal challenge: I decided to enroll, dedicating a good part of my free time, for a second university degree: I chose “Neuroeconomics”, an innovative academic path which combines psychology, economics, and neuroscience and studies how people make decisions and the role of the brain when people evaluate these decisions, categorizing risks and rewards and generally interacting with each other. I’ve been very glad to talk about my experience in this article, as working for Oracle is something very stimulating. This company ensures you the opportunity to face new challenges, work with highly talented people and be professionally highlighted also globally. Motivation, good results and innovation is always pursued, recognized and fully supported. Thanks and wish you all an amazing career! If you have any question please contact [email protected].

7 reasons you had to be at JavaOne Latin America 2012

- by Bruno.Borges

Yesterday was 12/12/12, and everybody went crazy on Twitter with cool memes like this one. And maybe you are now wondering why I mentioned 7 (seven) on the blog title. Because I want to play numbers? Yes! Today is 7 days after JavaOne Latin America 2012 is over (... and I had to figure out an excuse for taking so long to blog about it...). So unless you were at JavaOne Latin America this year, here are 7 things you missed: OTN Lounge mini-theatreThere was a mini-theatre holding several lightning talks. We had people from SouJava JUG, GoJava JUG, Globalcode, and several other Java gurus and companies running demos, talks, and even more. For example, @drspockbr talked about the ScrumToys project, that demonstrates the power of JSF. Hands On Lab for JAX-RS and WebSocketsOne of the cool things to do during JavaOne is to come to these Hands On labs and really do something using new technologies with the help of experts. This one in particular, was covered by me, Arun Gupta, and Reza Rahman. The HOL had more people than laptops (and we had 48 laptops!) interested on understanding and learning about the new stuff that is coming within Java EE 7. Things like JAX-RS, Server-sent Events and WebSockets. Hey, if you want to try this HOL by yourself, it is available on Github, so go for it! If you have questions, just let me know! Java Community KeynoteThis keynote presented a lot of cool things like startups using Java in their projects, the Duke Awards, SouJava winning the JCP Outstanding Award, the Java Band, and even more! It was really a space where the Java community could present what they are doing and what they want to do. There's a lot of interest on the Adopt-a-JSR program and the Adopt-OpenJDK. There's also an Adopt-a-JavaEE-JSR program! Take a look if you want to participate and Make the Future Java. Java EE (JMS, JAX-RS) sessions from Reza Rahman, the HeavyMetal guyReza is a well know professional and Java EE enthusiast from the communitty who just joined Oracle this year. His sessions were very well attended, perhaps because of a high interest on the new things coming to Java EE 7 like JMS 2.0 and JAX-RS 2.0. If you want to look at what he did at this JavaOne edition, read his blog post. By the way, if you like Java and heavymetal, you should follow him on Twitter as well! :-) Java EE (WebSockets, HTML5) sessions from Arun Gupta, the GlassFish guyIf you don't know Arun Gupta, no worries. You will have time to know about him while you read his Java EE 6 Pocket Guide. Arun has been evangelizing Java EE for a long time, and is now spreading his word about the new upcoming version Java EE 7. He gave one talk about HTML5 Productivity on the Java EE 7 platform, and another one on building web apps with WebSockets. Pretty neat! Arun blogged about JavaOne Latin America as well. Read it here. Java Embedded and JavaFXIf there are two things that are really trending in the Java World right now besides Java EE 7, certainly they are JavaFX and Java Embedded. There were 14 talks covering Java Embedded, from Java Cards to Raspberry.pi, from Java ME to Java on your TV with Ginga-J. The Internet of Things is becoming true, and Java is the only platform today that can connect it all in an standardized and concise way. JavaFX gained a lot of attention too. There were 8 sessions covering what the platform has to offer in terms of Rich User Experience. The JavaFX Scene Builder is an awesome tool to start playing designing an UI, and coding for JavaFX is like coding Swing with 8 hands, one holding your coffee cup. You can achieve a lot, with your two hands (unless, you really have 8 hands, then you can achieve 4 times more :-). If you want to read more about JavaFX, go to Stephen Chin's blog post. GlassFish and Friends Party, 1st edition at JavaOne Lating AmericaThis is probably the thing that I'm most proud. We brought to Brasil the tradition of holding a happy hour for all GlassFish, Java EE friends. This party started almost 7 years ago in San Francisco, and it was about time to bring it to Brazil! The party happened on Tuesday night, right after JavaOne General Keynote, at the Tribeca Pub. We had about 80 attendees and met a lot of Java EE developers there! People from JUGs, Oracle, Locaweb and Red Hat showed up too, including some execs from Oracle that didn't resist and could not miss a party like this one.Lots of caipirinhas, beer and food to everyone, some cool music... even The Fish walking around the party with Juggy!You can see more photos from the party on an album I shared with the recently created GlassFish Brasil community on Google+ here (but you may be more interested in joining the GlassFish english community). There's also more pictures that Arun took and shared on this link. So now you may want to consider coming to Brazil next year! Java EE 7 is on its way, and Brazil is happily and patiently waiting for it, with a lot of enthusiasm. By the way, GlassFish and Java EE 6 just celebrated a Happy Birthday!

XBRL - Moving from Production to Consumption

- by jmorourke

Here's an update on what’s new with XBRL and how it can actually benefit your organization versus adding extra time and costs to financial reporting. On February 29th (leap day) of 2012 I attended the XBRL and Financial Analysis Technology Conference at Baruch College in NYC. The event, which attracted over 300 XBRL gurus and fans was presented by XBRL US, The New York Society of Security Analysts’ Improved Corporate Reporting Committee, and Baruch College’s Robert Zicklin Center for Corporate Integrity. The event featured keynotes from the U.S. Securities and Exchange Commission (SEC), and the CFA Institute as well as panels covering alternative research tools and data, corporate reporting to stakeholders and a demonstration of XBRL analysis tools. The program culminated in a presentation of the finalists and the winner of the $20,000 XBRL Challenge. Some of the key points made in the sessions included: The focus of XBRL tools is moving from production to consumption. As of February 2012, over 9000 companies are reporting in XBRL, with over 10 million facts filed to date XBRL taxonomy extensions have dropped from 27% to 11% making comparisons easier The SEC reports that XBRL makes it easier to analyze disclosures, focus on accounting issues XBRL is helping standards-setters like the FASB speed their analysis of impacts of proposed accounting rule changes Companies like Thomson Reuters report that XBRL is helping speed the delivery of data to clients The most interesting part of the program though, was the session highlighting the 5 finalists in the XBRL Challenge competition and the winning solution. The XBRL Challenge was launched in 2011 as a means of spurring the development of more end-user tools to help with the consumption of XBRL-based financial information. Over an 8-month process handled by 5 judges, there were 84 registrants, 15 completed submissions, 5 finalists and one winner of the challenge. All of the solutions are open-sourced tools and most of them focus on consuming XBRL-based data. The 5 finalists included: Advanced XBRL Processing from Oxide solutions – XBRL viewer for taxonomies, filings and company data with peer comparison capabilities. Arrelle – API for XBRL processes, supports SEC Validations, RSS Feeds to access filings etc. Calcbench – XBRL data analysis tool that can be embedded in other web applications. This tool can combine XBRL filings with real-time market data. XBRL to XL – allows the importing of XBRL data into Microsoft Excel for analysis, comparisons. Users start on the web and populate Excel with XBRL data. XBurble – allows users to search and view XBRL filings, export to Excel, merge for comparison, and includes a workflow interface. The winner of the $20,000 XBRL Challenge prize was CalcBench. More information about the XBRL Challenge and the finalists can be found at www.XBRLUS.org/challenge XBRL for Sustainability Reporting – other recent news on the XBRL front was the announcement by the Global Reporting Initiative (GRI) of an XBRL taxonomy for Sustainability Reporting. This taxonomy was co-developed by the GRI and Deloitte and is designed to make the consumption of data found in Sustainability Reports much easier. Although there is no government mandate to file Sustainability Reports in XBRL format, organizations that do use the GRI guidelines for Sustainability Reporting are encouraged to tag and submit their data voluntarily to the GRI – who will populate a database with Sustainability Reporting data and make this available to the public. For more information about this initiative, you can go to the GRI web site: www.globalreporting.org. So how does all of this benefit corporate filers and investors? Since its introduction, the consensus in the market is that XBRL has mainly benefited the regulators and investment analysts who need to consume and analyze large volumes of financial data. But with the emergence of more end-user tools for consuming and analyzing XBRL-based data, and the ability to perform quick comparisons of one company versus its peers and competitors in an industry group, will soon accelerate the benefits to corporate finance staff, as well as individual investors. This could apply to financial results tagged in XBRL, as well as non-financial information such as Sustainability Reporting – which over the long-term will likely be integrated with financial reporting. And as multiple regulators and agencies in a country adopt the XBRL standard for corporate filings, more benefits will accrue as companies will be able to leverage one set of XBRL-based financial data for multiple regulatory filings. For more information about the latest developments in XBRL, check out the XBRL US or XBRL International web sites: www.xbrl.org, www.xbrlus.org. For more information about what Oracle is doing to support XBRL, here are some links: http://www.oracle.com/us/solutions/ent-performance-bi/disclosure-management-065892.html http://www.oracle.com/technetwork/database/features/xmldb/index-087631.html Feel free to contact me if you have any questions or need more information: [email protected]

Thread.Interrupt Is Evil

- by Alois Kraus

Recently I have found an interesting issue with Thread.Interrupt during application shutdown. Some application was crashing once a week and we had not really a clue what was the issue. Since it happened not very often it was left as is until we have got some memory dumps during the crash. A memory dump usually means WindDbg which I really like to use (I know I am one of the very few fans of it). After a quick analysis I did find that the main thread already had exited and the thread with the crash was stuck in a Monitor.Wait. Strange Indeed. Running the application a few thousand times under the debugger would potentially not have shown me what the reason was so I decided to what I call constructive debugging. I did create a simple Console application project and try to simulate the exact circumstances when the crash did happen from the information I have via memory dump and source code reading. The thread that was crashing was actually MS code from an old version of the Microsoft Caching Application Block. From reading the code I could conclude that the main thread did call the Dispose method on the CacheManger class which did call Thread.Interrupt on the cache scavenger thread which was just waiting for work to do. My first version of the repro looked like this static void Main(string[] args) { Thread t = new Thread(ThreadFunc) { IsBackground = true, Name = "Test Thread" }; t.Start(); Console.WriteLine("Interrupt Thread"); t.Interrupt(); } static void ThreadFunc() { while (true) { object value = Dequeue(); // block until unblocked or awaken via ThreadInterruptedException } } static object WaitObject = new object(); static object Dequeue() { object lret = "got value"; try { lock (WaitObject) { } } catch (ThreadInterruptedException) { Console.WriteLine("Got ThreadInterruptException"); lret = null; } return lret; } I do start a background thread and call Thread.Interrupt on it and then directly let the application terminate. The thread in the meantime does plenty of Monitor.Enter/Leave calls to simulate work on it. This first version did not crash. So I need to dig deeper. From the memory dump I did know that the finalizer thread was doing just some critical finalizers which were closing file handles. Ok lets add some long running finalizers to the sample. class FinalizableObject : CriticalFinalizerObject { ~FinalizableObject() { Console.WriteLine("Hi we are waiting to finalize now and block the finalizer thread for 5s."); Thread.Sleep(5000); } } class Program { static void Main(string[] args) { FinalizableObject fin = new FinalizableObject(); Thread t = new Thread(ThreadFunc) { IsBackground = true, Name = "Test Thread" }; t.Start(); Console.WriteLine("Interrupt Thread"); t.Interrupt(); GC.KeepAlive(fin); // prevent finalizing it too early // After leaving main the other thread is woken up via Thread.Abort // while we are finalizing. This causes a stackoverflow in the CLR ThreadAbortException handling at this time. } With this changed Main method and a blocking critical finalizer I did get my crash just like the real application. The funny thing is that this is actually a CLR bug. When the main method is left the CLR does suspend all threads except the finalizer thread and declares all objects as garbage. After the normal finalizers were called the critical finalizers are executed to e.g. free OS handles (usually). Remember that I did call Thread.Interrupt as one of the last methods in the Main method. The Interrupt method is actually asynchronous and does wake a thread up and throws a ThreadInterruptedException only once unlike Thread.Abort which does rethrow the exception when an exception handling clause is left. It seems that the CLR does not expect that a frozen thread does wake up again while the critical finalizers are executed. While trying to raise a ThreadInterrupedException the CLR goes down with an stack overflow. Ups not so nice. Why has this nobody noticed for years is my next question. As it turned out this error does only happen on the CLR for .NET 4.0 (x86 and x64). It does not show up in earlier or later versions of the CLR. I have reported this issue on connect here but so far it was not confirmed as a CLR bug. But I would be surprised if my console application was to blame for a stack overflow in my test thread in a Monitor.Wait call. What is the moral of this story? Thread.Abort is evil but Thread.Interrupt is too. It is so evil that even the CLR of .NET 4.0 contains a race condition during the CLR shutdown. When the CLR gurus can get it wrong the chances are high that you get it wrong too when you use this constructs. If you do not believe me see what Patrick Smacchia does blog about Thread.Abort and List.Sort. Not only the CLR creators can get it wrong. The BCL writers do sometimes have a hard time with correct exception handling as well. If you do tell me that you use Thread.Abort frequently and never had problems with it I do suspect that you do not have looked deep enough into your application to find such sporadic errors.

Openswan + xl2tpd connections time out after a while

- by Halfgaar

I have a non-NATed Openswan+xl2tpd server (Ubuntu 12.04), to which I connect with a Windows 8 behind NAT. The client loses its connection after a while of doing nothing (between 30 and 60 minutes, but I didn't time it). The client doesn't have enabled that it should kill inactive connections. Nor does it ever go into sleep mode. I also tried setting the kill-after-time to 24 hours, but that didn't help. The NAT router behind which the client located is Debian Linux, and its router is a Cisco which connects us directly to the data center where the server is. None of our other connections, like SSH, get dropped with inactivity (because of cheap routers). I did however try turning on the keepalives in /etc/ipsec.conf: config setup (...snip...) nat_traversal=yes force_keepalive=yes keep_alive=10 but that didn't help. As you can see in the config later, dead peer detection's action is clear. That would be a first suggestion to fix, but I need clear, because people will be connecting from everwhere but the kitchen sink. Besides, as I said, in the test setup I have now, I can't see any device killing its connection. (edit: 'restart' also has the same effect) These are of one time it happened: Jul 18 16:18:06 host xl2tpd[1918]: Maximum retries exceeded for tunnel 49070. Closing.

Time complexity of a sorting algorithm

- by Passonate Learner

The two programs below get n integers from file and calculates the sum of ath to bth integers q(number of question) times. I think the upper program has worse time complexity than the lower, but I'm having problems calculating the time complexity of these two algorithms. [input sample] 5 3 5 4 3 2 1 2 3 3 4 2 4 [output sample] 7 5 9 Program 1: #include <stdio.h> FILE *in=fopen("input.txt","r"); FILE *out=fopen("output.txt","w"); int n,q,a,b,sum; int data[1000]; int main() int i,j; fscanf(in,"%d%d",&n,&q); for(i=1;i<=n;i++) fscanf(in,"%d",&data[i]); for i=0;i<q;i++) { fscanf(in,"%d%d",&a,&b); sum=0; for(j=a;j<=b;j++) sum+=data[j]; fprintf(out,"%d\n",sum); } return 0; } Program 2: #include <stdio.h> FILE *in=fopen("input.txt","r"); FILE *out=fopen("output.txt","w"); int n,q,a,b; int data[1000]; int sum[1000]; int main() { int i,j; fscanf(in,"%d%d",&n,&q); for(i=1;i<=n;i++) fscanf(in,"%d",&data[i]); for(i=1;i<=n;i++) sum[i]=sum[i-1]+data[i]; for(i=0;i<q;i++) { fscanf(in,"%d%d",&a,&b); fprintf(out,"%d\n",sum[b]-sum[a-1]); } return 0; } The programs below gets n integers from 1 to m and sorts them. Again, I cannot calculate the time complexity. [input sample] 5 5 2 1 3 4 5 [output sample] 1 2 3 4 5 Program: #include <stdio.h> FILE *in=fopen("input.txt","r") FILE *out=fopen("output.txt","w") int n,m; int data[1000]; int count[1000]; int main() { int i,j; fscanf(in,"%d%d",&n,&m); for(i=0;i<n;i++) { fscanf(in,"%d",&data[i]); count[data[i]]++ } for(i=1;i<=m;i++) { for(j=0;j<count[i];j++) fprintf(out,"%d ",i); } return 0; } It's ironic(or not) that I cannot calculate the time complexity of my own algorithms, but I have passions to learn, so please programming gurus, help me!

Using QT to build a WYSIWYG Editor for a Custom Markup Language

- by Aaron

I'm new to QT, and am trying to figure out the best means of creating a WYSIWYG editor widget for a custom markup language that displays simple text, images, and links. I need to be able to propagate changes from the WYSIWYG editor to the custom markup representation. As a concrete example of the problem domain, imagine that the custom markup might have a "player" tag which contains a player name and a team name. The markup could look like this: Last week, <player id="1234"><name>Aaron Rodgers</name><team>Packers</team></player> threw a pass. This text would display in the editor as: Last week, Aaron Rodgers of the Packers threw a pass. The player name and the team name would be editable directly within the editor in standard WYSIWYG fashion, so that my users do not have to learn any markup. Also, when the player name is moused-over, a details pop-up will appear about that player, and similarly for the team. With that long introduction, I'm trying to figure out where to start with QT. It seems that the most logical option would be the Rich Text API using a QTextDocument. This approach seems less than ideal given the limitations of a QTextDocument: I can't figure out how to capture navigation events from clicking on links. Following links on click seems to only be enabled when the QTextEdit is readonly. Custom objects that implement QTextObjectInterface are ignored in copy-and-paste operations Any HTML-based markup that is passed to it as Rich Text is retranslated into a series of span tags and lots of other junk, making it extremely difficult to propagate changes from the editor back to the original custom markup. A second option appears to be QWebKit, which allows for live editing of HTML5 markup, so I could specify a two-way translation between the custom markup and HTML5. I'm not clear on how one would propagate changes from the editor back to the original markup in real-time without re-translating the entire document on every text change. The QWebKit solutions looks like awfully bulky to me (Learning WebKit along with QT) to what should be a relatively simple problem. I have also considered implementing the WYSIWYG with a custom class using native QT containers, labels, images, and other widgets manually. This seems like the most flexible approach, and the one most likely not to run into unresolvable problems. However, I'm pretty sure that implementing all the details of a normal text editor (selecting text, font changes, cut-and-paste support, undo/redo, dragging of objects, cursor placement, etc.) will be incredibly time consuming. So, finally, my question: are there any QT gurus out there with some advice on where to start with this sort of project? BTW, I am using QT because the application is a desktop application that needs platform independence.

Is it possible to change HANDLE that has been opened for synchronous I/O to be opened for asynchrono

- by Martin Dobšík

Dear all, Most of my daily programming work in Windows is nowadays around I/O operations of all kind (pipes, consoles, files, sockets, ...). I am well aware of different methods of reading and writing from/to different kinds of handles (Synchronous, asynchronous waiting for completion on events, waiting on file HANDLEs, I/O completion ports, and alertable I/O). We use many of those. For some of our applications it would be very useful to have only one way to treat all handles. I mean, the program may not know, what kind of handle it has received and we would like to use, let's say, I/O completion ports for all. So first I would ask: Let's assume I have a handle: HANDLE h; which has been received by my process for I/O from somewhere. Is there any easy and reliable way to find out what flags it has been created with? The main flag in question is FILE_FLAG_OVERLAPPED. The only way known to me so far, is to try to register such handle into I/O completion port (using CreateIoCompletionPort()). If that succeeds the handle has been created with FILE_FLAG_OVERLAPPED. But then only I/O completion port must be used, as the handle can not be unregistered from it without closing the HANDLE h itself. Providing there is an easy a way to determine presence of FILE_FLAG_OVERLAPPED, there would come my second question: Is there any way how to add such flag to already existing handle? That would make a handle that has been originally open for synchronous operations to be open for asynchronous. Would there be a way how to create opposite (remove the FILE_FLAG_OVERLAPPED to create synchronous handle from asynchronous)? I have not found any direct way after reading through MSDN and googling a lot. Would there be at least some trick that could do the same? Like re-creating the handle in same way using CreateFile() function or something similar? Something even partly documented or not documented at all? The main place where I would need this, is to determine the the way (or change the way) process should read/write from handles sent to it by third party applications. We can not control how third party products create their handles. Dear Windows gurus: help please! With regards Martin

hand coding a parser

- by John Leidegren

For all you compiler gurus, I wanna write a recursive descent parser and I wanna do it with just code. No generating lexers and parsers from some other grammar and don't tell me to read the dragon book, i'll come around to that eventually. I wanna get into the gritty details about implementing a lexer and parser for a reasonable simple langauge, say CSS. And I wanna do this right. This will probably end up being a series of questions but right now I'm starting with a lexer. Tokenization rules for CSS can be found here. I find my self writing code like this (hopefully you can infer the rest from this snippet): public CssToken ReadNext() { int val; while ((val = _reader.Read()) != -1) { var c = (char)val; switch (_stack.Top) { case ParserState.Init: if (c == ' ') { continue; // ignore } else if (c == '.') { _stack.Transition(ParserState.SubIdent, ParserState.Init); } break; case ParserState.SubIdent: if (c == '-') { _token.Append(c); } _stack.Transition(ParserState.SubNMBegin); break; What is this called? and how far off am I from something reasonable well understood? I'm trying to balence something which is fair in terms of efficiency and easy to work with, using a stack to implement some kind of state machine is working quite well, but I'm unsure how to continue like this. What I have is an input stream, from which I can read 1 character at a time. I don't do any look a head right now, I just read the character then depending on the current state try to do something with that. I'd really like to get into the mind set of writing reusable snippets of code. This Transition method is currently means to do that, it will pop the current state of the stack and then push the arguments in reverse order. That way, when I write Transition(ParserState.SubIdent, ParserState.Init) it will "call" a sub routine SubIdent which will, when complete, return to the Init state. The parser will be implemented in much the same way, currently, having everyhing in a single big method like this allows me to easily return a token when I found one, but it also forces me to keep everything in one single big method. Is there a nice way to split these tokenization rules into seperate methods? Any input/advice on the matter would be greatly appriciated!

Issues in Ada Concurrency

- by Arkapravo

Hi I need some help and also some insight. This is a program in Ada-2005 which has 3 tasks. The output is 'z'. If the 3 tasks do not happen in the order of their placement in the program then output can vary from z = 2, z = 1 to z = 0 ( That is easy to see in the program, mutual exclusion is attempted to make sure output is z = 2). WITH Ada.Text_IO; USE Ada.Text_IO; WITH Ada.Integer_Text_IO; USE Ada.Integer_Text_IO; WITH System; USE System; procedure xyz is x : Integer := 0; y : Integer := 0; z : Integer := 0; task task1 is pragma Priority(System.Default_Priority + 3); end task1; task task2 is pragma Priority(System.Default_Priority + 2); end task2; task task3 is pragma Priority(System.Default_Priority + 1); end task3; task body task1 is begin x := x + 1; end task1; task body task2 is begin y := x + y; end task2; task body task3 is begin z := x + y + z; end task3; begin Put(" z = "); Put(z); end xyz; I first tried this program (a) without pragmas, the result : In 100 tries, occurence of 2: 86, occurence of 1: 10, occurence of 0: 4. Then (b) with pragmas, the result : In 100 tries, occurence of 2: 84, occurence of 1 : 14, occurence of 0: 2. Which is unexpected as the 2 results are nearly identical. Which means pragmas or no pragmas the output has same behavior. Those who are Ada concurrency Gurus please shed some light on this topic. Alternative solutions with semaphores (if possible) is also invited. Further in my opinion for a critical process (that is what we do with Ada), with pragmas the result should be z = 2, 100% at all times, hence or otherwise this program should be termed as 85% critical !!!! (That should not be so with Ada)

How to designing a generic databse whos layout may change over time?

- by mawg

Here's a tricky one - how do I programatically create and interrogate a database who's contents I can't really foresee? I am implementing a generic input form system. The user can create PHP forms with a WYSIWYG layout and use them for any purpose he wishes. He can also query the input. So, we have three stages: a form is designed and generated. This is a one-off procedure, although the form can be edited later. This designs the database. someone or several people make use of the form - say for daily sales reports, stock keeping, payroll, etc. Their input to the forms is written to the database. others, maybe management, can query the database and generate reports. Since these forms are generic, I can't predict the database structure - other than to say that it will reflect HTML form fields and consist of a the data input from collection of edit boxes, memos, radio buttons and the like. Questions and remarks: A) how can I best structure the database, in terms of tables and columns? What about primary keys? My first thought was to use the control name to identify each column, then I realized that the user can edit the form and rename, so that maybe "name" becomes "employee" or "wages" becomes ":salary". I am leaning towards a unique number for each. B) how best to key the rows? I was thinking of a timestamp to allow me to query and a column for the row Id from A) C) I have to handle column rename/insert/delete. Foe deletion, I am unsure whether to delete the data from the database. Even if the user is not inputting it from the form any more he may wish to query what was previously entered. Or there may be some legal requirements to retain the data. Any gotchas in column rename/insert/delete? D) For the querying, I can have my PHP interrogate the database to get column names and generate a form with a list where each entry has a database column name, a checkbox to say if it should be used in the query and, based on column type, some selection criteria. That ought to be enough to build searches like "position = 'senior salesman' and salary 50k". E) I probably have to generate some fancy charts - graphs, histograms, pie charts, etc for query results of numerical data over time. I need to find some good FOSS PHP for this. F) What else have I forgotten? This all seems very tricky to me, but I am database n00b - maybe it is simple to you gurus?

Silverlight? WPF? or Windows Form?

- by Amit

After Silverlight 4.0 has been released with new WPF, I am kind of confused with these technologies: Silverlight? WPF? Windows Form? The main motive that we want to achieve for BIG business project is following: Performance Security And platform independent** If I consider all above three points then only Silverlight is the option as I don’t want people buying emulator on MacOS for WPF or Windows Form. Now how good the Silverlight is for Business applications, I was completely against when Silverlight 2.0 was in the market but now it is Silverlight 4.0 and they have provided many new features (but still basics) that is required in any challenging business applications. Comparing Silverlight and WPF -* Silverlight and WPF are very new technology and if I'd to compare from these two then I'd prefer WPF because it can be considered stable and mature. But it is not same as Windows Form. -* If I go with Silverlight then I am sure about keep updating to the latest version of Silverlight. I remembered when we were developing software for version 2.0 then we'd to create our own framework with dynamic loading DLL, and then Navigation concept. But everything was got changed once Silverlight 3.0 came. I don't want this to be happening with this new product. -* If we go with WPF then we don't get the platform independence. Now, why not we just focus on making WPF and then move to Silverlght. As someone (Tim?) from Microsoft has said that the idea is to make Silverlight as close as WPF. But if that is the case then why XAML structure is different; I will not be convinced with by saying that .Net framework for SL is too small.. well the difference is coming from the namespace ? I was searching on this subject and found "Microsoft WPF-Silverlight Comparison Whitepaper v1.1.pdf". This guide is very good that gives you ins-outs about how can we build common apps that runs on both. But again, it is comparing Silverlight 2 and not 4. I am sure many architect/ developers/ project managers must be facing similar kind of questions in their premises and wants to initiate this discussion, if it has not been :). We've still got 2 weeks to make this decision, so I'm expecting everyone to participate, gurus?

Don't know how much sense does it makes, but i have this: <ul> <li><a href="page1.html">Support</a></li> <li><a href="page2.html">Products</a></li> <li><a href="page3.html">Management</a></li> <li><a href="page4.html">Others</a></li> </ul> and I need soothing like this: <ul> <li> <a href="page1.html">Support</a> <div class="slideLink"><a href="page1.html">Click Here</a></div> </li> <li> <a href="page2.html">Products</a> <div class="slideLink"><a href="page2.html">Click Here</a></div> </li> <li> <a href="page3.html">Management</a> <div class="slideLink"><a href="page3.html">Click Here</a></div> </li> <li> <a href="page4.html">Others</a> <div class="slideLink"><a href="page4.html">Click Here</a></div> </li> </ul> So far I have managed to add div with class and link within it with "click here" text, but i don't have a clue how to grab link href and add it to my new link. $('ul li a').each(function(){ $(this).after("<div class='slideLink'><a href=" + Link + ">Read more</div>"); }); Thank you for your help in advance. Best Regards Dom

Why does my entire page reload in Chrome and Firefox when using asynchronous UpdatePanel postbacks?

- by Alex

Being a bit perplexed about this issue by now, I hope some of you gurus can shed some light on my problem... I've developed a AJAX-enhanced website, which has been running fine in IE, Chrome and Firefox for a year or so. I use a Timer-control to check for incoming messages every 30 seconds, and this updates an UpdatePanel showing potential new messages. Now several one of my Firefox users complain about the page refreshing every 30 seconds! I my self cannot reproduce this behaviour, but given the "30 seconds"-description, I cursed my Timer-solution as the culprit. But now, I'm experiencing this error myself, not in Firefox though, but in Google Chrome! (And only on one of my two computers!) Every 30 seconds the page reloads! But I found that it's not only related to the Timer, because all other asynchronous postbacks to the server within UpdatePanels reloads the entire page as well. This error has never been experienced in Internet Explorer (to my knowledge). As I said, this it not only related to the Timer postback, but if it's of interest to anybody the code is like this: <asp:Timer runat="server" ID="MailCheckTimer" Interval="30000" OnTick="MailChecker_Tick"></asp:Timer> <asp:UpdatePanel runat="server" ID="MailCheckerUpdatePanel" UpdateMode="Conditional"> <ContentTemplate> <div class="newmail_box" runat="server" id="newmail_box">  </div> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="MailCheckTimer" /> </Triggers> </asp:UpdatePanel> In other places of the website I call the client side __doPostBack function directly from JavaScript in relation to an UpdatePanel. Normal behaviour for this call is to updated the referenced UpdatePanel with some content, but now in Chrome this refreshes the entire page! (but again not consistently, and never in IE) Even the most fundamental UpdatePanel operations like refreshing the content after a button (inside the panel) is clicked, forces the page to reload completely: <asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click"></asp:Button> And just to torment me further, I only experience this on my public website, and not in my local development environment, making it a tedious affair for me to find the actual cause! :( Any ideas on why this happens? Why so inconsistently? Has it to do with my UpdatePanel-design? Or does some security setting in Firefox/Chrome that prevent some asynchronous UpdatePanel callbacks? Any help or idea is highly appreciated!
