• Exceptional DBA Awards 2011

  - by Rebecca Amos

  From today, we’re accepting nominations for the 2011 Exceptional DBA Awards. DBAs make a vital contribution to the running of the companies they work for, and the Exceptional DBA Awards aim to acknowledge this and make this contribution more widely known. Check out our new website for all the info: www.exceptionaldba.com  Being an exceptional DBA doesn’t mean you have to sleep at the office, or know everything there is to know about SQL Server; who ever could? It means that you make an effort to make your servers secure and reliable, and to make your users’ lives easier. Maybe you’ve helped a junior colleague learn something new about server backups? Or cancelled your coffee break to get a database back online? Or contributed to a forum post on performance monitoring? All of these actions show that you might be an exceptional DBA. So have a think about the tasks you do every day that already make you exceptional – and then get started on your entry! You just need to answer a few questions on our website about your experience as a DBA, some of your biggest achievements, and any other activities you participate in within the SQL Server community. Anyone who is currently working as a SQL Server database administrator can enter, or be nominated by someone else. We’ve got four fantastic judges for the Awards, who you’ll be familiar with already: Brent Ozar, Brad McGehee, Rodney Landrum and Steve Jones. They’ll pick five finalists, and then we’ll ask the SQL Server community to vote for their winner. Not only could you win the respect and recognition of peers and colleagues, but the prizes also include full conference registration for the 2011 PASS Summit in Seattle (where the awards ceremony will take place), four nights' hotel accommodation, and $300 towards travel expenses. The winner will get a copy of Red Gate’s SQL DBA Bundle – and they’ll also be featured here, on Simple-Talk. So what are you waiting for? Chances are you’ve already made a small effort for someone today that means you might be an exceptional DBA. Visit the website now, and start writing your entry – or nominate your favourite DBA to enter: www.exceptionaldba.com

• Customer Support Spotlight: Clemson University

  - by cwarticki

  I've begun a Customer Support Spotlight series that highlights our wonderful customers and Oracle loyalists.  A week ago I visited Clemson University.  As I travel to visit and educate our customers, I provide many useful tips/tricks and support best practices (as found on my blog and twitter). Most of all, I always discover an Oracle gem who deserves recognition for their hard work and advocacy. Meet George Manley.  George is a Storage Engineer who has worked in Clemson's Data Center all through college, partially in the Hardware Architecture group and partially in the Storage group. George and the rest of the Storage Team work with most all of the storage technologies that they have here at Clemson. This includes a wide array of different vendors' disk arrays, with the most of them being Oracle/Sun 2540's.  He also works with SAM/QFS, ACSLS, and our SL8500 Tape Libraries (all three Oracle/Sun products). (pictured L to R, Matt Schoger (Oracle), Mark Flores (Oracle) and George Manley) George was kind enough to take us for a data center tour.  It was amazing.  I rarely get to see the inside of data centers, and this one was massive. Clemson Computing and Information Technology’s physical resources include the main data center located in the Information Technology Center at the Innovation Campus and Technology Park. The core of Clemson’s computing infrastructure, the data center has 21,000 sq ft of raised floor and is powered by a 14MW substation. The ITC power capacity is 4.5MW.  The data center is the home of both enterprise and HPC systems, and is staffed by CCIT staff on a 24 hour basis from a state of the art network operations center within the ITC. A smaller business continuance data center is located on the main campus.  The data center serves a wide variety of purposes including HPC (supercomputing) resources which are shared with other Universities throughout the state, the state's medicaid processing system, and nearly all other needs for Clemson University. Yes, that's no typo (14,256 cores and 37TB of memory!!! Thanks for the tour George and thank you very much for your time.  The tour was fantastic. I enjoyed getting to know your team and I look forward to many successes from Clemson using Oracle products. -Chris WartickiGlobal Customer Management

• Recording Topics manually and automatically

  - by maria.cozzolino(at)oracle.com

  When you are recording UPK topics, the default mode for recording is manual recording, where you tell the system when to record each screen shot. This mode allows you to take the exact screen shot you need. However, it does get a bit tedious when you are recording long topics, especially if you forget to take a few screen shots. In UPK 3.5, a new version of recording was introduced - Automatic Recording. It was designed to simplify the recording process by automatically capturing screen shots as you perform your transaction. If you haven't experimented with Automatic Recording, I'd recommend you give it a try - it might make your recording life easier. If you are recording with sound, you can also narrate your topic while recording it. To turn on Automatic Recording: 1. In Tools/Options, there are two recorder tabs. The first tab, under content defaults, includes settings that you may want to share between developers, like whether keyboard shortcuts are automatically captured. 2. The second tab is the one that contains the personal preferences, like screen shot capture key and whether to record automatically or manually. On this tab, choose the option for Automatic Recording. 3. Save the settings. Note that this setting will NOT impact content defaults; this is for your user only. When you launch the recorder, you will notice a slightly different message with guidance on how to start and stop automatic recording. Once you start recording, the recorder window is hidden until the end of the recording session to allow you to capture your transaction. In the task tray, there is a series of icons that let you know that you are capturing content. You can pause the recording, as well as set and view your sound levels if you are using sound. A camera appears during each screen capture to help you know when the system is capturing a screen shot, and a context indicator appears to show the recognition. With automatic recording, you can let the system capture the necessary screen shots. It may provide a more natural recording experience, and is probably easier for the untrained developer. On the other hand, you have a bit more control with manual recording on which screen shot appears, but it also means you have to remember to capture the screen shot. :) We'd be interested in hearing which type of recording you do, and any rationale on why you made that choice. Please comment and let us know. --Maria Cozzolino, Manager of UPK Software Requirements and UI Design

• How do you play or record audio (to .WAV) on Linux in C++? [closed]

  - by Jacky Alcine

  Hello, I've been looking for a way to play and record audio on a Linux (preferably Ubuntu) system. I'm currently working on a front-end to a voice recognition toolkit that'll automate a few steps required to adapt a voice model for PocketSphinx and Julius. Suggestions of alternative means of audio input/output are welcome, as well as a fix to the bug shown below. Here is the current code I've used so far to play a .WAV file: void Engine::sayText ( const string OutputText ) { string audioUri = "temp.wav"; string requestUri = this->getRequestUri( OPENMARY_PROCESS , OutputText.c_str( ) ); int error , audioStream; pa_simple *pulseConnection; pa_sample_spec simpleSpecs; simpleSpecs.format = PA_SAMPLE_S16LE; simpleSpecs.rate = 44100; simpleSpecs.channels = 2; eprintf( E_MESSAGE , "Generating audio for '%s' from '%s'..." , OutputText.c_str( ) , requestUri.c_str( ) ); FILE* audio = this->getHttpFile( requestUri , audioUri ); fclose(audio); eprintf( E_MESSAGE , "Generated audio."); if ( ( audioStream = open( audioUri.c_str( ) , O_RDONLY ) ) < 0 ) { fprintf( stderr , __FILE__": open() failed: %s\n" , strerror( errno ) ); goto finish; } if ( dup2( audioStream , STDIN_FILENO ) < 0 ) { fprintf( stderr , __FILE__": dup2() failed: %s\n" , strerror( errno ) ); goto finish; } close( audioStream ); pulseConnection = pa_simple_new( NULL , "AudioPush" , PA_STREAM_PLAYBACK , NULL , "openMary C++" , &simpleSpecs , NULL , NULL , &error ); for (int i = 0;;i++ ) { const int bufferSize = 1024; uint8_t audioBuffer[bufferSize]; ssize_t r; eprintf( E_MESSAGE , "Buffering %d..",i); /* Read some data ... */ if ( ( r = read( STDIN_FILENO , audioBuffer , sizeof (audioBuffer ) ) ) <= 0 ) { if ( r == 0 ) /* EOF */ break; eprintf( E_ERROR , __FILE__": read() failed: %s\n" , strerror( errno ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } /* ... and play it */ if ( pa_simple_write( pulseConnection , audioBuffer , ( size_t ) r , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_write() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } usleep(2); } /* Make sure that every single sample was played */ if ( pa_simple_drain( pulseConnection , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_drain() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } } NOTE: If you want the rest of the code to this file, you can download it here directly from Launchpad.

• Transparent Technology from Amazon

  - by David Dorf

  Amazon has been making some interesting moves again, this time in the augmented humanity area.  Augmented humanity is about helping humans overcome their shortcomings using technology.  Putting a powerful smartphone in your pocket helps you in many ways like navigating streets, communicating with far off friends, and accessing information.  But the interface for smartphones is somewhat limiting and unnatural, so companies have been looking for ways to make the technology more transparent and therefore easier to use. When Apple helped us drop the stylus, we took a giant leap forward in simplicity.  Using touchscreens with intuitive gestures was part of the iPhone's original appeal.  People don't want to know that technology is there -- they just want the benefits.  So what's the next leap beyond the touchscreen to make smartphones even easier to use? Two natural ways we interact with the world around us is by using sight and voice.  Google and Apple have been using both in their mobile platforms for limited uses cases.  Nobody actually wants to type a text message, so why not just speak it?  Any if you want more information about a book, why not just snap a picture of the cover?  That's much more accurate than trying to key the title and/or author. So what's Amazon been doing?  First, Amazon released a new iPhone app called Flow that allows iPhone users to see information about products in context.  Yes, its an augmented reality app that uses the phone's camera to view products, and overlays data about the products on the screen.  For the most part it requires the barcode to be visible to correctly identify the product, but I believe it can also recognize certain logos as well.  Download the app and try it out but don't expect perfection.  Its good enough to demonstrate the concept, but its far from accurate enough.  (MobileBeat did a pretty good review.)  Extrapolate to the future and we might just have a heads-up display in our eyeglasses. The second interesting area is voice response, for which Siri is getting lots of attention.  Amazon may have purchased a voice recognition company called Yap, although the deal is not confirmed.  But it would make perfect sense, especially with the Kindle Fire in Amazon's lineup. I believe over the next 3-5 years the way in which we interact with smartphones will mature, and they will become more transparent yet more important to our daily lives.  This will, of course, impact the way we shop, making information more readily accessible than it already is.  Amazon seems to be positioning itself to be at the forefront of this trend, so we should be watching them carefully.

• Bad Data is Really the Monster

Sinha writes: “Bad or missing data makes application systems fail when they process order-level data. One of the key items in the supply-chain industry is the product (aka SKU). Therefore, it becomes the most important data element to tie up multiple merchandising processes including purchase order allocation, stock movement, shipping notifications, and inventory details… Bad data can cause huge operational failures and cost millions of dollars in terms of time, resources, and money to clean up and validate data across multiple participating systems. Yes bad data really is the monster, so what do we do about it? Close our eyes and hope it stays in the closet? We’ve tacked this problem for some years now at Oracle, and with our latest introduction of Oracle Enterprise Data Quality along with our integrated Oracle Master Data Management products provides a complete, best-in-class answer to the bad data monster. What’s unique about it? Oracle Enterprise Data Quality also combines powerful data profiling, cleansing, matching, and monitoring capabilities while offering unparalleled ease of use. What makes it unique is that it has dedicated capabilities to address the distinct challenges of both customer and product data quality – [different monsters have different needs of course!]. And the ability to profile data is just as important to identify and measure poor quality data and identify new rules and requirements. Included are semantic and pattern-based recognition to accurately parse and standardize data that is poorly structured. Finally all of the data quality components are integrated with Oracle Master Data Management, including Oracle Customer Hub and Oracle Product Hub, as well as Oracle Data Integrator Enterprise Edition and Oracle CRM. Want to learn more? On Tuesday Nov 15th, I invite you to listen to our webcast on Reduce ERP consolidation risks with Oracle Master Data Management I’ll be joined by our partner iGate Patni and be talking about one specific way to deal with the bad data monster specifically around ERP consolidation. Look forward to seeing you there!

• A Community Cure for a String Splitting Headache

  - by Tony Davis

  A heartwarming tale of dogged perseverance and Community collaboration to solve some SQL Server string-related headaches. Michael J Swart posted a blog this week that had me smiling in recognition and agreement, describing how an inquisitive Developer or DBA deals with a problem. It's a three-step process, starting with discomfort and anxiety; a feeling that one doesn't know as much about one's chosen specialized subject as previously thought. It progresses through a phase of intense research and learning until finally one achieves breakthrough, blessed relief and renewed optimism. In this case, the discomfort was provoked by the mystery of massively high CPU when searching Unicode strings in SQL Server. Michael explored the problem via Stack Overflow, Google and Twitter #sqlhelp, finally leading to resolution and a blog post that shared what he learned. Perfect; except that sometimes you have to be prepared to share what you've learned so far, while still mired in the phase of nagging discomfort. A good recent example of this recently can be found on our own blogs. Despite being a loud advocate of the lightning fast T-SQL-based string splitting techniques, honed to near perfection over many years by Jeff Moden and others, Phil Factor retained a dogged conviction that, in theory, shredding element-based XML using XQuery ought to be even more efficient for splitting a string to create a table. After some careful testing, he found instead that the XML way performed and scaled miserably by comparison. Somewhat subdued, and with a nagging feeling that perhaps he was still missing "something", he posted his findings. What happened next was a joy to behold; the community jumped in to suggest subtle changes in approach, using an attribute-based rather than element-based XML list, and tweaking the XQuery shredding. The result was performance and scalability that surpassed all other techniques. I asked Phil how quickly he would have arrived at the real breakthrough on his own. His candid answer was "never". Both are great examples of the power of Community learning and the latter in particular the importance of being brave enough to parade one's ignorance. Perhaps Jeff Moden will accept the string-splitting gauntlet one more time. To quote the great man: you've just got to love this community! If you've an interesting tale to tell about being helped to a significant breakthrough for a problem by the community, I'd love to hear about it. Cheers, Tony.

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

• Planning Bulletin for JRE 7: What EBS Customers Can Do Today

  - by Steven Chan (Oracle Development)

  An initiative to certify Oracle E-Business Suite with JRE 7 desktop clients is underway.  We have tested EBS 11.5.10.2, 12.0, and 12.1 with JRE 7. We have fixes for nearly all of the compatibility issues now, and are working hard to produce the remaining fixes quickly. A. When will JRE 7 be certified with Oracle E-Business Suite? We will announce the certification of the E-Business Suite with JRE 7 once all fixes are available, verified, and documented.  Certification announcements will be distributed through My Oracle Support, My Oracle Support Community Forums, Oracle Technology Network Forums, newsletters, and user group news outlets. Oracle's Revenue Recognition rules prohibit us from discussing certification and release dates.  In addition to the standard communication channels listed above, customers are encouraged to monitor or subscribe to this blog.    B. What can customers do to prepare for the JRE 7 certification? Customers should ensure that they are on the latest available JRE 6 update. Of the compatibility issues identified so far with JRE 7, the most critical is an issue that prevents E-Business Suite Forms-based products from launching on Windows desktops that are running JRE 7.  Customers can prevent this issue today by ensuring that they have applied the latest certified patches documented for JRE 6 configurations to their EBS application tier servers: Apply Forms patch 14615390 to EBS 11i environments (Note 125767.1) Apply Forms patch 14614795 to EBS 12.0 and 12.1 environments (Note 437878.1) These patches are compatible with JRE 6 and 7, production ready, and fully-tested with the E-Business Suite.  These patches may be applied immediately to all E-Business Suite environments. All other Forms prerequisites documented in the Notes above should also be applied now. C. What else will be required by the final certified configuration? Oracle expects that all other compatibility issues will be resolved by installing a specific JRE 7 release, at minimum.  That specific release has not been finalized yet, and this is subject to change. D.  Where will the official patch requirements be documented? All patches required for ensuring full compatibility of the E-Business Suite with JRE 7 will be documented in updates to these published Notes: For EBS 11i: Deploying Sun JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite Release 11i (Note 290807.1) Upgrading Developer 6i with Oracle E-Business Suite 11i (Note 125767.1) For EBS 12 Deploying Sun JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite Release 12 (Note 393931.1) Upgrading OracleAS 10g Forms and Reports in Oracle E-Business Suite Release 12 (Note 437878.1) Disclaimer The preceding is intended to outline our general product direction.  It is intended for information purposes only, and may not be incorporated into any contract.   It is not a commitment to deliver any material, code, or functionality, and should not be relied upon in making purchasing decision.  The development, release, and timing of any features or functionality described for Oracle’s products remains at the sole discretion of Oracle.

• Ivy bridge i3 recognized as Xeon e3-1200

  - by user287072

  The situation: I've got a Ivy bridge i3 3225 which is being recognized as a Xeon e3-1200 series cpu by Ubuntu 14.04 64bit. The problem: cpu fan makes more noise than necessary (under dual-boot Win8 the fans are off), cannot install the intel graphics drivers from 01.org. Goals: - find a fix for the load fans could be they are not CPU related, I've tried some fan controller packages, but they made no difference. - get the intel graphics to install (this now fails as xeon cpu's are not supported, I got the package working on a i5 laptop) - get to know some more about how hardware recognition works Tried so far: - a reinstall of Ubuntu, but it was recognized again as a Xeon cpu. - different fan control packages, but they either do not recognized the fans, or just keep fan speed to high. Any pointers as how to get Ubuntu recognized it are more than welcome. lspci -nnQ 00:00.0 Host bridge [0600]: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor DRAM Controller [8086:0150] (rev 09) 00:01.0 PCI bridge [0604]: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor PCI Express Root Port [8086:0151] (rev 09) 00:14.0 USB controller [0c03]: Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller [8086:1e31] (rev 04) 00:16.0 Communication controller [0780]: Intel Corporation 7 Series/C210 Series Chipset Family MEI Controller #1 [8086:1e3a] (rev 04) 00:1a.0 USB controller [0c03]: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #2 [8086:1e2d] (rev 04) 00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04) 00:1c.0 PCI bridge [0604]: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 1 [8086:1e10] (rev c4) 00:1c.5 PCI bridge [0604]: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 6 [8086:1e1a] (rev c4) 00:1c.6 PCI bridge [0604]: Intel Corporation 82801 PCI Bridge [8086:244e] (rev c4) 00:1d.0 USB controller [0c03]: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #1 [8086:1e26] (rev 04) 00:1f.0 ISA bridge [0601]: Intel Corporation Z77 Express Chipset LPC Controller [8086:1e44] (rev 04) 00:1f.2 SATA controller [0106]: Intel Corporation 7 Series/C210 Series Chipset Family 6-port SATA Controller [AHCI mode] [8086:1e02] (rev 04) 00:1f.3 SMBus [0c05]: Intel Corporation 7 Series/C210 Series Chipset Family SMBus Controller [8086:1e22] (rev 04) 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK106 [GeForce GTX 660] [10de:11c0] (rev a1) 01:00.1 Audio device [0403]: NVIDIA Corporation GK106 HDMI Audio Controller [10de:0e0b] (rev a1) 03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.

• Alfa AWUS036H USB wireless adapter not recognized

  - by GFiasco

  The Alfa AWUS036H USB wireless adapter will not be recognized by my netbook (Ubuntu 14.04, Asus X201E). As I understand it, the drivers should already be built in to this version of Linux, but I tried a make/make install of the latest Realtek drivers (as mentioned on How do I install drivers for the Alfa AWUS036H USB wireless adapter?) and it didn't work. I then followed the advice of this thread (ALFA AWUS036NH driver) and did a make/make install of the most up-to-date backport of the drivers, but that didn't work. At this point I tried a series of commands from this thread (http://ubuntuforums.org/showthread.php?t=2187780) in an attempt to identify the problem, but at no point could I get the laptop to ever recognize the USB adapter. I have also troubleshot the USB cable itself, tried both the USB 2.0 and 3.0 ports on the laptop, have never received an error message regarding a need to update the firmware, and have seemingly successfully installed all manner of variation of Realtek drivers which were supposed to make the adapter work. (I also tried to delete/clean up after each install, in the hope I wasn't making things worse.) Not sure what I should do next. Please let me know if I need to post any more information. Thanks very much for your help. EDIT: Before inserting Alpha USB adapter: :~$ lsusb Bus 002 Device 002: ID 8087:0024 Intel Corp.

• Announcing Key Functional White Papers for SIM and ReIM

  - by Oracle Retail Documentation Team

  Oracle Retail has published two new documents on My Oracle Support (https://support.oracle.com)  that provide partners and retailers with deeper functional information about two products: Oracle Retail Store Inventory Management (SIM) and Oracle Retail Invoice Matching. Oracle Retail Store Inventory Management Item Configuration White Paper (Doc ID 1507221.1) There is functionality within the Store Inventory Management system related to item configuration that spans across multiple concepts that apply to the application as a whole rather than to a specific area. This white paper covers numerous topics around item configuration including: Item Transaction Levels Item Long Description Pack Size Standard Unit of Measure Standard Unit of Measure Conversion Pack Items Simple Pack Conversion Items (Notional Packs) Ranging Items Item Status Non-Sellable Items Type-2 Item Recognition UPC-E Barcodes Non-Inventory Items Consignment and Concession Items Quick Response Codes Oracle Retail Invoice Matching Financial Transactions (Doc ID 1500209.1) This document explains the financial transactions that are posted by Oracle Retail Invoice Matching (ReIM). The scope of the document is limited to ReIM transactions only, and does not explain Retail Merchandising System (RMS), Finance, or Account Receivable transactions. ReIM follows the double-entry accounting standard, which works by recording the debit and credit of each financial transaction belonging to each party involved. Each transaction means a profit to one account (debit) and a loss to another account (credit). Full invoice match processing is completed in ReIM with payment recommendations communicated to Oracle Accounts Payable. ReIM matches merchandise orders and receipts against merchandise invoices, performing automated and manual matching, as well as discrepancy-resolution processing. Matched invoices are posted to interface staging tables specifying the amount and date to pay, vendor, site ID, General Ledger Chart of Accounts (GL CoA) information, and payment terms. Other payables documents, including debit memos, credit memos and credit notes are also interfaced to Accounts Payable through the ReIM staging tables (IM_AP_STAGE_HEAD and IM_AP_STAGE_DETAIL). For information about how ReIM engages in this processing, see the latest Oracle Retail Invoice Matching Operations Guide. Certain ReIM transactions are not interfaced to Oracle Payables, but instead are interfaced to Oracle General Ledger through the IM_FINANCIAL_STAGE table. When analyzing transactions posted through the staging tables, retailers should note the transaction type, Standard/Credit, as well as the sign in the amount field. Technically, a negative sign on a credit transaction changes the transaction to a debit entry, and vice versa. This document is concerned about the financial meaning of the transactions, and will avoid a discussion of negative numbers in T-charts.

• Writing OpenGL enabled GUI

  - by Jaen

  I am exploring a possibility to write a kind of a notebook analogue that would reproduce the look and feel of using a traditional notebook, but with the added benefit of customizing the page in ways you can't do on paper - ask the program to lay ruled paper here, grid paper there, paste an image, insert a recording from the built-in camera, try to do handwriting recognition on the tablet input, insert some latex for neat formulas and so on. I'm pretty interested in developing it just to see if writing notes on computer can come anywhere close to the comfort plain paper + pencil offer (hard to do IMO) and can always turn it in as a university C++ project, so double gain there. Coming from the type of project there are certain requirements for the user interface: the user will be able to zoom, move and rotate the notebook as he wishes and I think it's pretty sensible delegate it to OpenGL, so the prospective GUI needs to work well with OGL (preferably being rendered in it) the interface should be navigable with as little of keyboard input as user wishes (incorporating some sort of gestures maybe) up to limiting the keyboard keys as modifiers to the pen movements and taps; this includes tablet and possible multitouch support the interface should keep out of the way where not needed and come up where needed and be easily layerable the notebook sheet itself will be a container for objects representing the notebook blurbs, so it would be nice if the GUI would be able to overlay some frames over the exact parts of the OpenGL-drawn sheet to signify what can be done with given part (like moving, rotating, deleting, copying, editing etc.) and it's extents In terms of interface it's probably going to end up similar to Alias' Sketch Book Pro: [picture][http://1.bp.blogspot.com/_GGxlzvZW-CY/SeKYA_oBdSI/AAAAAAAAErE/J6A0kyXiuqA/s400/Autodesk_Alias_SketchBook_Pro_2.jpg] As far as toolkits go I'm considering Qt and nui, but I'm not really aware how well would they match up the requirements and how well would they handle such an application. As far as I know you can somehow coerce Qt into doing widget drawing with OpenGL, but on the other hand I heard voices it's slot-signal framework isn't exactly optimal and requires it's own preprocessor and I don't know how hard would be to do all the custom widgets I would need (say color-wheel, ruler, blurb frames, blurb selection, tablet-targeted pop-up menu etc.) in the constraints of Qt. Also quite a few Qt programs I've had on my machine seemed really sluggish, but it may be attributed to me having old PC or programmers using Qt suboptimally rather to the framework itself. As for [nui][http://www.libnui.net/] I know it's also cross-platform and all of the basic things you would require of a GUI toolkit and what is the biggest plus it is OpenGL-enabled from the start, but I don't know how it is with custom widgets and other facets and it certainly has smaller userbase and less elaborate documentation than Qt. The question goes as this: Does any of these toolkits fulfill (preferably all of) the requirements or there is a well fitting toolkit I haven't come across or maybe I should just roll up my sleeves, get SFML (or maybe Clutter would be more suited to this?) and something like FastDelegates or libsigc++ and program the GUI framework from the ground up myself? I would be very glad if anyone had experience with a similar GUI project and can offer some comments on how well these toolkits hold up or is it worthwhile to pursue own GUI toolkit in this case. Sorry for longwindedness, duh.

• Best photo management software?

  - by Niels Basjes

  Hi, What I would like is a single piece of software (or a smart combination of tools) that allow me to manage my photos in a better way than what I've found so far. 1. Tags Primarily I need a way of tagging the images. So I can manually tag photos the same way we tag questions here at SO/SF/SU. I want this software to place a lot of the tags automagically (obvious things like date and resolution). 2. Face recognition What I would really like is that this software has a feature that it can recognize faces in images and places tags with the name of the person. So far I've only heard of one online photo system that can do that (Picasa) and not yet of any offline tool. 3. Version database I must have some way of having a central GIT/SVN/... that contains all images. I have had a harddrive corruption a few years ago and it took me a long time to figure out which images had been damaged. I always want to be able to go back to what the camera produced. 4. Website I want to be able to generate a website (few 'tag' specific websites) based on the actual content. 5. Easy bulk uploading Many photo tools have a one on one uploading option. I prefer simply 'throwing' my images on a file server under Linux (Samba) and let the system automagically integrate, tag, recognize, etc. all images. Ok, I know these are a bit much. Perhaps you guy's have some suggestions about existing tools that can make this possible. Or even a complete system that does this. EDIT: To clarify on the OS. I prefer Linux for any 'server' task and Windows XP for any 'desktop' task. Thanks for all your input. Niels Basjes

• Compress a folder of PDF files into separate zip archives

  - by Panrubius

  I wanted to take a folder full of PDF files and create a number of separate zip files, after following the advice on this question everything worked *almost*perfectly. Here's what happened: When I issued this command in Terminal: zip -s 5m -r ~/Desktop/invoices ~/Desktop/Invoices/ Everything worked really well, in that I got 11 ZIP files of approximately 5 MB each; placed in the folder specified. However, the files they outputted were named as follows: invoices.z01 invoices.z02 invoices.z03 invoices.z04 invoices.z05 invoices.z06 invoices.z07 invoices.z08 invoices.z09 invoices.z10 invoices.zip So as you can see only invoices.zip has been named correctly. I could go through and rename them one by one, but seriously, if we start doing that then what in the name of Evolution are computers for?! Now, I am also aware that I'm relatively new to the Terminal; so I could be making a very silly mistake somewhere. If that's the case, please be patient :-) Any help would be greatly appreciated. One last note: I'm quadriplegic so I would like to avoid GUI applications as much as possible, I use voice recognition software you see this working in the Terminal is much much easier.

• IP Blacklists and suspicious inbound and outbound traffic

  - by Pantelis Sopasakis

  I administer a web server and recently we had our IP banned (!) from our host after they received a notification e-mail for abuse. In particular our server is allegedly involved in spam attacks over HTTP. The content of the abuse report email we received was not much informative - for example the IP addresses our server is supposed to have attacked against are not included - so I started a wireshark session checking for suspicious traffic over TCP/HTTP while trying to locate possible security holes on the system. (Let me note that the machine runs a Debian OS). Here is an example of such a request... Source: 89.74.188.233 Destination: 12.34.56.78 // my ip Protocol: HTTP Info: GET 'http://www.media.apniworld.com/image.php?type=hv' HTTP/1.0 I manually blacklisted this host (as well as some other ones) blocking them with iptables, but I can't keep on doing manually all day long... I'm looking for an automated way to block such IPs based on: Statistical analysis, pattern recognition or other AI-based analysis (Though, I'm reluctant to trust such a solution, if exists) Public blacklists Using DNSBL I actually found out that 89.74.188.233 is blacklisted. However other IPs which are strongly suspicious like 93.199.112.126 (i.e. http://www.pornstarnetwork.com/account/signin), unfortunately were not blacklisted! What I would like to do is to automatically connect my firewall with DNSBL (or some other blacklist database) and block all traffic towards blacklisted IPs or somehow have my local blacklist automatically updated.

• Backup Picasa 'people' tags data

  - by pelms

  OK, so I've spent a fair amount of time putting names to faces in Picasa 3.5 but in a few days (hopefully) my copy of Windows 7 should arrive and I'll need to reinstall Windows. So, does anyone know what I need to backup so that I don't have to re-enter all those name tags? N.B. I'm on Windows 7 RC and know that I don't have to do a clean reinstall but I would prefer to. Outcome: I clean installed Windows 7 and downloaded and installed Picasa. Unfortunately, the download link on the UK Picasa homepage still pointed to Picasa 3.0 (rather than 3.5) which doesn't have face recognition. This scanned my photos folders and overwrote the picasa.ini files along with the people information   :¬( Fortunately I'd backed up the photos before installing Win 7, so after uninstalling Picasa 3.0 (along with it's database), restoring the photos from backup and installing Picasa 3.5, I finally got my face names back. Extra... Google has now posted advice on how to migrate to Windows 7 and keep your Picasa database, meaning that it will not need to rescan you photos and will retain all information about then including name tags. They have a method for upgrading and for a clean install of Win 7. Basically you need to back up: "C:\Users\%username%\AppData\Local\Google\Picasa2" and "C:\Users\%username%\AppData\Local\Google\Picasa2Albums"

• How to find Stolen MacBook with iCloud

  - by user1518089

  My MacBook Air was stolen about 6 weeks ago. Through iCloud and "Find Phone", I have some pictures and a location down to about 2 blocks. The pictures are from the current user taking photos which automatically appear on my local devices. (Yes they probably saw my pictures until I stopped taking them. Yes, they are stupid.) I was thinking about going there and hanging out until I recognized the current users, but it is in a very bad neighborhood and I would be noticed. The police have not done anything. Yes, the MacBook can be locked or a message sent. I am hoping to get it back. Does anyone have ideas on how to track them down? While Find Phone shows their location, it does not report an ip address. Is there a way to get an ip address? Does Facebook face recognition work on strangers? Come on tech geniuses, help me play detective. It does not have Drop Box installed.
