• Oracle Social Network Developer Challenge: Fishbowl Solutions

  - by Kellsey Ruppel

  Originally posted by Jake Kuramoto on The Apps Lab blog. Today, I give you the final entry in the Oracle Social Network Developer Challenge, held last week during OpenWorld. This one comes from Friend of the ‘Lab and Fishbowl Solutions (@fishbowle20) hacker, John Sim (@jrsim_uix), whom you might remember from his XBox Kinect demo at COLLABORATE 12 (presentation slides and abstract) hacks and other exploits with WebCenter. We put this challenge together specifically for developers like John, who like to experiment with new tools and push the envelope of what’s possible and build cool things, and as you can see from his entry John did just that, mashing together Google Maps and Oracle Social Network into a mobile app built with PhoneGap that uses the device’s camera and GPS to keep teams on the move in touch. He calls it a Mobile GeoTagging Solution, but I think Avengers Assemble! would have equally descriptive, given that was obviously his inspiration. Here’s his description of the mobile app: My proposed solution was to design and simplify GeoLocation mapping, and automate updates for users and teams on the move; who don’t have access to a laptop or want to take their ipads out – but allow them to make quick updates to OSN and upload photos taken from their mobile device – there and then. As part of this; the plan was to include a rules engine that could be configured by the user to allow the device to automatically update and post messages when they arrived at a set location(s). Inspiration for this came from on{x} – automate your life. Unfortunately, John didn’t make it to the conference to show off his hard work in person, but luckily, he had a colleague from Fishbowl and a video to showcase his work.    Here are some shots of John’s mobile app for your viewing pleasure: John’s thinking is sound. Geolocation is usually relegated to consumer use cases, thanks to services like foursquare, but distributed teams working on projects out in the world definitely need a way to stay in contact. Consider a construction job. Different contractors all converge on a single location, and time is money. Rather than calling or texting each other and risking a distracted driving accident, an app like John’s allows everyone on the job to see exactly where the other contractors are. Using his GPS rules, they could easily be notified about how close each is to the site, definitely useful when you have a flooring contractor sitting idle, waiting for an electrician to finish the wiring. The best part is that the project manager or general contractor could stay updated on all the action (or inaction) using Oracle Social Network, either sitting at a desk using the browser app or desktop client or on the go, using one of the native mobile apps built for Oracle Social Network. I can see this being used by insurance adjusters too, and really any team that, erm, assembles at a given spot. Of course, it’s also useful for meeting at the pub after the day’s work is done. Beyond people, this solution could also be implemented for physical objects that are in route to a destination. Say you’re a customer waiting on rail shipment or a package delivery. You could track your valuable’s whereabouts easily as they report their progress via checkins. If they deviated from the GPS rules, you’d be notified. You might even be able to get a picture into Oracle Social Network with some light hacking. Thanks to John and his colleagues at Fishbowl for participating in our challenge. We hope everyone had a good experience. Make sure to check out John’s blog post on his work and the experience using Oracle Social Network. Although this is the final, official entry we had, tomorrow, I’ll show you the work of someone who finished code, but wasn’t able to make the judging event. Stay tuned.

• Joy! | Important Information About Your iPad 3G

  - by Jeff Julian

  Looks like I was one of the lucky 114,000 who AT&T lost their email to “hackers”.  Why is “hackers” in “double quotes”.  I can just imagine some executive at AT&T in their “Oh No, We Messed Up Meeting” saying, what happened?  Then someone replied, well we have had a breach and “hackers” broke in (using the quote in the air gesture) and stole our iPad 3G customers emails. Oh well, I am sure my email has been sold and sold again by many different vendors, why not AT&T now.  At least Dorothy Attwood could have gave us her email to give to someone else instead of blinking it through a newsletter system. June 13, 2010 Dear Valued AT&T Customer, Recently there was an issue that affected some of our customers with AT&T 3G service for iPad resulting in the release of their customer email addresses. I am writing to let you know that no other information was exposed and the matter has been resolved.  We apologize for the incident and any inconvenience it may have caused. Rest assured, you can continue to use your AT&T 3G service on your iPad with confidence. Here’s some additional detail: On June 7 we learned that unauthorized computer “hackers” maliciously exploited a function designed to make your iPad log-in process faster by pre-populating an AT&T authentication page with the email address you used to register your iPad for 3G service.  The self-described hackers wrote software code to randomly generate numbers that mimicked serial numbers of the AT&T SIM card for iPad – called the integrated circuit card identification (ICC-ID) – and repeatedly queried an AT&T web address.   When a number generated by the hackers matched an actual ICC-ID, the authentication page log-in screen was returned to the hackers with the email address associated with the ICC-ID already populated on the log-in screen. The hackers deliberately went to great efforts with a random program to extract possible ICC-IDs and capture customer email addresses.  They then put together a list of these emails and distributed it for their own publicity. As soon as we became aware of this situation, we took swift action to prevent any further unauthorized exposure of customer email addresses.  Within hours, AT&T disabled the mechanism that automatically populated the email address. Now, the authentication page log-in screen requires the user to enter both their email address and their password. I want to assure you that the email address and ICC-ID were the only information that was accessible. Your password, account information, the contents of your email, and any other personal information were never at risk.  The hackers never had access to AT&T communications or data networks, or your iPad.  AT&T 3G service for other mobile devices was not affected. While the attack was limited to email address and ICC-ID data, we encourage you to be alert to scams that could attempt to use this information to obtain other data or send you unwanted email. You can learn more about phishing by visiting the AT&T website. AT&T takes your privacy seriously and does not tolerate unauthorized access to its customers’ information or company websites.   We will cooperate with law enforcement in any investigation of unauthorized system access and to prosecute violators to the fullest extent of the law. AT&T acted quickly to protect your information – and we promise to keep working around the clock to keep your information safe.  Thank you very much for your understanding, and for being an AT&T customer. Sincerely, Dorothy Attwood Senior Vice President, Public Policy and Chief Privacy Officer for AT&T Technorati Tags: AT&T,iPad 3G,Email

• Windows Azure Recipe: Social Web / Big Media

  - by Clint Edmonson

  With the rise of social media there’s been an explosion of special interest media web sites on the web. From athletics to board games to funny animal behaviors, you can bet there’s a group of people somewhere on the web talking about it. Social media sites allow us to interact, share experiences, and bond with like minded enthusiasts around the globe. And through the power of software, we can follow trends in these unique domains in real time. Drivers Reach Scalability Media hosting Global distribution Solution Here’s a sketch of how a social media application might be built out on Windows Azure: Ingredients Traffic Manager (optional) – can be used to provide hosting and load balancing across different instances and/or data centers. Perfect if the solution needs to be delivered to different cultures or regions around the world. Access Control – this service is essential to managing user identity. It’s backed by a full blown implementation of Active Directory and allows the definition and management of users, groups, and roles. A pre-built ASP.NET membership provider is included in the training kit to leverage this capability but it’s also flexible enough to be combined with external Identity providers including Windows LiveID, Google, Yahoo!, and Facebook. The provider model has extensibility points to hook into other identity providers as well. Web Role – hosts the core of the web application and presents a central social hub users. Database – used to store core operational, functional, and workflow data for the solution’s web services. Caching (optional) – as a web site traffic grows caching can be leveraged to keep frequently used read-only, user specific, and application resource data in a high-speed distributed in-memory for faster response times and ultimately higher scalability without spinning up more web and worker roles. It includes a token based security model that works alongside the Access Control service. Tables (optional) – for semi-structured data streams that don’t need relational integrity such as conversations, comments, or activity streams, tables provide a faster and more flexible way to store this kind of historical data. Blobs (optional) – users may be creating or uploading large volumes of heterogeneous data such as documents or rich media. Blob storage provides a scalable, resilient way to store terabytes of user data. The storage facilities can also integrate with the Access Control service to ensure users’ data is delivered securely. Content Delivery Network (CDN) (optional) – for sites that service users around the globe, the CDN is an extension to blob storage that, when enabled, will automatically cache frequently accessed blobs and static site content at edge data centers around the world. The data can be delivered statically or streamed in the case of rich media content. Training These links point to online Windows Azure training labs and resources where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure (16 labs) Windows Azure is an internet-scale cloud computing and services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services which can be used individually or together. It gives developers the choice to build web applications; applications running on connected devices, PCs, or servers; or hybrid solutions offering the best of both worlds. New or enhanced applications can be built using existing skills with the Visual Studio development environment and the .NET Framework. With its standards-based and interoperable approach, the services platform supports multiple internet protocols, including HTTP, REST, SOAP, and plain XML SQL Azure (7 labs) Microsoft SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. Windows Azure Services (9 labs) As applications collaborate across organizational boundaries, ensuring secure transactions across disparate security domains is crucial but difficult to implement. Windows Azure Services provides hosted authentication and access control using powerful, secure, standards-based infrastructure. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

• 24 Hours of PASS coming up soon!

  - by Rob Farley

  Massive thanks to all the people that have been shouting about this event already. I’ve seen quite a number of blog posts about it, and rather than listing some and missing others, please assume I’ve noticed your blog and accept my thanks. But in case this is all news to you – the next 24 Hours of PASS event is less than a fortnight away (Sep 20/21)! And there’s lots of info about it at http://www.sqlpass.org/24hours/fall2012/  (Don’t ask why it’s “Fall 2012”. Apparently that’s what this time of year is called in at least two countries. I would call it “Spring”, personally, but do appreciate that it’s “Autumn” in the Northern Hemisphere...) Yes, I blogged about it on the PASS blog a few weeks ago, but haven’t got around to writing about it here yet. As always, 24HOP is going to have some amazing content. But it’s going to be pointing at the larger event, which now less than two months away. That’s right, this 24HOP is the Summit 2012 Preview event. Most of the precon speakers are going to be represented, as are half-day session presenters, quite a few of the Spotlight presenters and some of the Microsoft speakers too. When you look down the list of sessions at http://www.sqlpass.org/24hours/fall2012/SessionsbySchedule.aspx, you’ll find yourself wondering how you can fit them all in. Luckily, that’s not my problem. For me, it’s just about making sure that you can get to hear these people present, and get a taste for the amazing time that you’ll have if you can come to the Summit. I see this 24HOP as the kind of thing that will just drive you crazy if you can’t get to the Summit. There will be so much great content, and every one of these presenters will be delivering even more than this at the Summit itself. If you tune into Jason Strate’s 24HOP session on the Plan Cache and are impressed – well, you can get to a longer session by him on that same topic at the Summit. And the same goes for all of them. If you’re anything like me, you’ll find yourself looking at the Summit schedule, wishing you could get to several presentations for every time slot. So get yourself registered for 24HOP and help yourself make that decision. And if you can’t go to the Summit, tune in anyway. You’ll still learn a lot, and you might just be able to help persuade someone to send you to the Summit after all (before the price goes up after Sep 30).

• Development-led security vs administration-led security in a software product?

  - by haylem

  There are cases where you have the opportunity, as a developer, to enforce stricter security features and protections on a software, though they could very well be managed at an environmental level (ie, the operating system would take care of it). Where would you say you draw the line, and what elements do you factor in your decision? Concrete Examples User Management is the OS's responsibility Not exactly meant as a security feature, but in a similar case Google Chrome used to not allow separate profiles. The invoked reason (though it now supports multiple profiles for a same OS user) used to be that user management was the operating system's responsibility. Disabling Web-Form Fields A recurrent request I see addressed online is to have auto-completion be disabled on form fields. Auto-completion didn't exist in old browsers, and was a welcome feature at the time it was introduced for people who needed to fill in forms often. But it also brought in some security concerns, and so some browsers started to implement, on top of the (obviously needed) setting in their own preference/customization panel, an autocomplete attribute for form or input fields. And this has now been introduced into the upcoming HTML5 standard. For browsers that do not listen to this attribute, strange hacks* are offered, like generating unique IDs and names for fields to avoid them from being suggested in future forms (which comes with another herd of issues, like polluting your local auto-fill cache and not preventing a password from being stored in it, but instead probably duplicating its occurences). In this particular case, and others, I'd argue that this is a user setting and that it's the user's desire and the user's responsibility to enable or disable auto-fill (by disabling the feature altogether). And if it is based on an internal policy and security requirement in a corporate environment, then substitute the user for the administrator in the above. I assume it could be counter-argued that the user may want to access non-critical applications (or sites) with this handy feature enabled, and critical applications with this feature disabled. But then I'd think that's what security zones are for (in some browsers), or the sign that you need a more secure (and dedicated) environment / account to use these applications. * I obviously don't deny the ingeniosity of the people who were forced to find workarounds, just the necessity of said workarounds. Questions That was a tad long-winded, so I guess my questions are: Would you in general consider it to be the application's (hence, the developer's) responsiblity? Where do you draw the line, if not in the "general" case?

• The Windows 8 and Ubuntu 12.04 Dual Boot NIghtmare

  - by Steve

  I have done some research as to how to go about this dual-boot, and I am close, but I need some guidance with booting into Windows 8 (Ubuntu is installed). I have a Lenovo Ideapad y510p. I will go over what I have done to dual-boot this laptop, with windows 8 pre-installed, with Ubuntu 12.04: I followed every instruction to the letter for the 97-vote response here, and everything worked fine up until after the repair boot section: Installing on a Pre-Installed Windows 8 System (UEFI Supported) I ran into the following error upon restarting after the repair boot section: error: invalid arch independent elf magic. This error (a grub issue) disabled me from booting into Ubuntu :( After a little googling, I followed the instructions in the reactivating grub 2 section to resolve the error: http://kb.acronis.com/content/1686 I found a possible solution to fixing the Windows 8 boot issue, and tried it: http://webcache.googleusercontent.com/search?q=cache:i9JMyXzzRpYJ:askubuntu.com/questions/279275/dual-boot-problem-windows-8-ubuntu-12-04+&cd=1&hl=en&ct=clnk&gl=us&client=ubuntu I thought the above solution worked, but when I attempt to boot into Windows 8, I get the following missing file error: File: \Boot\BCD Status: 0xc000000e Info: The Boot Configuration Data for your PC is missing or contains errors. Here is some other information that may be useful: I have 3 partitions devoted to Ubuntu. The first, sda8, has a flag bios_grub (1049 kb). The second, sda9, is where everything else is (96.6 GB). The last, sda10, is for swap (8299 MB). My question is: How do I fix the boot configuration for Windows 8? Any help would be greatly appreciated :) Update 1: When I attempt to boot into UEFI mode, I get the following error: invalid arch independent elf magic (the same error I saw in step 2). Update 2: A useful link here I found: Dual booting Ubuntu 12.04: UEFI and Legacy So, this is my 4th time installing Ubuntu on the laptop, and it looks like I need to install it in UEFI mode. Should I scrap it all again, and reinstall? Or is there ANY way of salvaging my installation? At this point, I can't even boot into Windows (although I have an installation cd to fix the windows boot issue, that would ultimately screw over ubuntu). Update 3: After doing a little more browsing around, I found a cool way around this messy grub stuff, using rEFInd. Rod Smith's post here saved me! Installing ubuntu 12.04.02 in uefi mode Now, I am able to dual-boot Windows 8 and Ubuntu and boot into both operating systems :) I have another issue (relating to the boot configuration in the bios) that I will post as a separate question :)

• Missing Indexes DMV Report, 3 billion Impact!

  - by Tara Kizer

  We’ve been having some major performance issues with one of the applications that I support.  The database is on SQL Server 2005 and is about 150GB in size.  We’ve identified a couple of issues already on the database side.  The first issue is that some query (or maybe several queries) is getting a bad execution plan at some point in time during the day.  When it occurs, database performance comes to a grinding halt.  We know it’s a bad execution plan as running DBCC FREEPROCCACHE immediately resolves the problem system-wide.  As we have not yet identified the problematic query, we’ve put a temporary solution in place that frees the procedure cache on an hourly basis via a SQL Agent job.  This is not ideal, but it is getting us through the day without a major problem.  We are actively working on identifying the problematic query and hope to disable the SQL Agent job soon. Earlier this week, we had a major slowdown for one of the processes of this application.  I was unable to find any database performance issues, but I continued to investigate it.  One of things that I typically do when investigating database performance issues is run the “Missing Indexes DMV Report” (that’s what I call it at least).  When analyzing the output of that report, I immediately dismiss anything under 1 million “Impact” as I want to target the “low-hanging fruit” initially.  When I ran the report earlier this week, I was shocked to find a suggested index with an impact of over 3 billion! Do I win a prize for the highest impact?  Has anyone seen a value higher than mine?  My exact value was 3154284120.67765. The performance issue from earlier this week ended up being an application problem, but it also brought to light a much needed index.  I had previously seen this index come up in that report but always with a much lower impact.  I had never considered it as the index’s selectivity is very low.  It’s a composite index with three columns.  The first column is not selective, the first two columns are not selective, and the three columns together are not selective.  In fact, no matter how I order it, the index will not be selective at all.  I briefly discussed this with Kimberly Tripp, and she said that this was okay for covering indexes.  Selectivity is irrelevant for a covering index.  She indicated that she’s even created indexes with gender as the first column in the index.  I’ve got lots to learn still!

• Get Your Enterprise Working With Oracle On Track Communication 1.0

  - by Josh Lannin

  The On Track Development team is very pleased to announce that today On Track is available for our customers to download and evaluate.  To learn more about what On Track does start with our whitepaper and datasheet.   If you are a developer, take a look at our documentation and samples posted to our OTN page. For this first blog post, I’ll be speaking to several notable points about our product. Graceful Escalation via Conversations: On Track addresses the “Collaboration Problem” through a single guiding principle – graceful escalation – within the construct of a Conversation. In On Track, collaboration is based on a context (called a “Conversation”) that gracefully escalates in form, structure, and content, as dictated by the particular needs of a given collaboration.  Within that context, On Track provides a rich set of tools to choose from.  These tools provide for communication, coordination, content management, organization, decision making, and analysis -- all essential aspects of collaboration, but not all of them are essential all of the time.  Every collaborative interaction will evolve differently.  Some will evolve to represent work spreading over the course of years and involving a large, distributed team, while others may involve few people and not evolve at all.  Regardless, all collaborative contexts are built from the same parts, utilize the same concepts, and start the same way.  The principle of graceful escalation is that you only use the tools and structure you need; so you only incur the complexity you need. Purposeful Collaboration: Through application integration, On Track Conversations bring enterprise application users the communication and collaboration capabilities required to complete business process.  By association with specific processes or business objects conversations extend the possible interactions and broaden participation to internal or external non-application users and provide a sophisticated interaction experience, all the while enhancing the data set within the owning application.  Purposeful collaboration not only needs to happen in the context of applications, it must support a full range of real-time and long-running interactions to provide the greatest value. Multi Client, Multi Modal: This On Track 1.0 product release includes the same day availability of  multiple clients, including iPhone and iPad applications which are now available on the Apple Store, a fully capable and accessible Outlook Add-In, along with our browser web client.  With each client we have sought to leverage the strengths of each unique device- our iPhone client supports picture and voice posts, the iPad is optimized for meeting room situations and document viewing, and our Outlook add-in allows you to take emails in context and bring them into On Track.  In addition to supporting a diverse array of clients, On Track provides a unified multi modal experience support starting with basic messages moving through to integrated documents with live annotations, snapshots, application sharing, and voice. Next Generation Web Architecture: We believe On Track will help move the bar higher for what users can expect from all web applications, most notably ones that involve real-time activity.  On Track is built from the ground up with an innovative, real-time architecture that leverages the extensive push capabilities of our server.  Whether you are receiving a new message, viewing where crowds of people are collaborating, or doing live annotation on a document with a set of people, that information comes to you immediately without refreshes or moving back and forth between pages.  We’ve leveraged this core architecture across the product experience and raised the user experience bar for this type of application.  As well these capabilities are based on open standards and protocols, and are fully extensible by anyone- enabling sophisticated integrations to be created with a wide variety of both legacy and next-generation applications. Agile Product Development: As a product team we operate using continuous feedback and modified agile development methodologies.  We have thousands of active internal Oracle users who have helped pilot our product for critical business functions, and the On Track product development team uses our product as our primary vehicle for all our collaboration.  Additionally we been working with early access customers who are adopting our technology and providing us valuable feedback - which our process has rapidly realized in improvements to our software.  On Track agility extends to our server as well, which is built to scale, and is very simple to install and configure. We are pleased to make this product announcement and encourage you to join us on Facebook or follow us on Twitter, as well as checking back here for the latest product information.

• Subterranean IL: Volatile

  This time, we'll be having a look at the volatile. prefix instruction, and one of the differences between volatile in IL and C#. The volatile. prefix volatile is a tricky one, as there's varying levels of documentation on it. From what I can see, it has two effects: It prevents caching of the load or store value; rather than reading or writing to a cached version of the memory location (say, the processor register or cache), it forces the value to be loaded or stored at the 'actual' memory location, so it is then immediately visible to other threads. It forces a memory barrier at the prefixed instruction. This ensures instructions don't get re-ordered around the volatile instruction. This is slightly more complicated than it first seems, and only seems to matter on certain architectures. For more details, Joe Duffy has a blog post going into the details. For this post, I'll be concentrating on the first aspect of volatile. Caching field accesses To demonstrate this, I created a simple multithreaded IL program. It boils down to the following code: .class public Holder { .field public static class Holder holder .field public bool stop .method public static specialname void .cctor() { newobj instance void Holder::.ctor() stsfld class Holder Holder::holder ret }}.method private static void Main() { .entrypoint // Thread t = new Thread(new ThreadStart(DoWork)) // t.Start() // Thread.Sleep(2000) // Console.WriteLine("Stopping thread...") ldsfld class Holder Holder::holder ldc.i4.1 stfld bool Holder::stop call instance void [mscorlib]System.Threading.Thread::Join() ret}.method private static void DoWork() { ldsfld class Holder Holder::holder // while (!Holder.holder.stop) {} DoWork: dup ldfld bool Holder::stop brfalse DoWork pop ret} If you compile and run this code, you'll find that the call to Thread.Join() never returns - the DoWork spinlock is reading a cached version of Holder.stop, which is never being updated with the new value set by the Main method. Adding volatile to the ldfld fixes this: dupvolatile.ldfld bool Holder::stopbrfalse DoWork The volatile ldfld forces the field access to read direct from heap memory, which is then updated by the main thread, rather than using a cached copy. volatile in C# This highlights one of the differences between IL and C#. In IL, volatile only applies to the prefixed instruction, whereas in C#, volatile is specified on a field to indicate that all accesses to that field should be volatile (interestingly, there's no mention of the 'no caching' aspect of volatile in the C# spec; it only focuses on the memory barrier aspect). Furthermore, this information needs to be stored within the assembly somehow, as such a field might be accessed directly from outside the assembly, but there's no concept of a 'volatile field' in IL! How this information is stored with the field will be the subject of my next post.

• HighPoint RocketRAID 62x Controller

  - by TeXnewbie

  I have the subject card recently installed in Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-31-generic x86_64). See partial lspci -vv listing below (complete listing played havoc with pre tags): 03:00.0 RAID bus controller: HighPoint Technologies, Inc. Device 0622 (rev 01) Subsystem: HighPoint Technologies, Inc. Device 0001 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Latency: 0, Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 11 Region 0: I/O ports at 9c00 [size=8] Region 1: I/O ports at 9800 [size=4] Region 2: I/O ports at 9400 [size=8] Region 3: I/O ports at 9000 [size=4] Region 4: I/O ports at 8c00 [size=16] Region 5: Memory at fdbff000 (32-bit, non-prefetchable) [size=2K] Expansion ROM at fdbe0000 [disabled] [size=64K] Capabilities: I followed instructions I found at https://help.ubuntu.com/community/RocketRaid to compile the drivers for it, and although performing the process described there seemed to work fine with no noticeable errors, when I rebooted after performing that procedure I could not boot. During dkms steps, I noticed messages indicating that (If next boot fails, revert to initrd.img-3.2.0-31-generic.old-dkms image) update-initramfs................ so I booted using a Ubuntu 12.10 LiveDVD and reverted to the old-dkms initrd.img as suggested above, but this failed to repair the boot problem. Ultimately, I used https://help.ubuntu.com/community/Boot-Repair in Ubuntu-Secure-Remix to fix the boot problem and was able to boot normally again, but now with the newly generated initrd.img in place again (which now boots normally), when I modprobe the rr62x kernel module, I immediately get a hard crash with messages to console about a kernel paging request that seems to have caused the problem. I've tried on multiple occasions now to use the newly built kernel module so as to allow me to use an eSATA port multiplier plugged into the card, but to no avail. Any suggestions on fixes or workarounds (I've read that some of the HighPoint cards (2720SGL) seem to work as a host bus adapter and thus may not need a custom driver, but that seems not to be the case for mine) would be most appreciated. My goal is to use the card as described here and with software RAID mdadm utilities. If necessary, I can hand-copy the console messages after the hard crash into a follow-up message, but I obviously can't do a cut/paste. I'll gladly provide any other details that are needed, but not sure what those would be at this point, so I'll refrain from adding other details for now. Thanks in advance for any help.

• Create a Remote Git Repository from an Existing XCode Repository

  - by codeWithoutFear

  Introduction Distributed version control systems (VCS’s), like Git, provide a rich set of features for managing source code.  Many development tools, including XCode, provide built-in support for various VCS’s.  These tools provide simple configuration with limited customization to get you up and running quickly while still providing the safety net of basic version control. I hate losing (and re-doing) work.  I have OCD when it comes to saving and versioning source code.  Save early, save often, and commit to the VCS often.  I also hate merging code.  Smaller and more frequent commits enable me to minimize merge time and effort as well. The work flow I prefer even for personal exploratory projects is: Make small local changes to the codebase to create an incrementally improved (and working) system. Commit these changes to the local repository.  Local repositories are quick to access, function even while offline, and provides the confidence to continue making bold changes to the system.  After all, I can easily recover to a recent working state. Repeat 1 & 2 until the codebase contains “significant” functionality and I have connectivity to the remote repository. Push the accumulated changes to the remote repository.  The smaller the change set, the less likely extensive merging will be required.  Smaller is better, IMHO. The remote repository typically has a greater degree of fault tolerance and active management dedicated to it.  This can be as simple as a network share that is backed up nightly or as complex as dedicated hardware with specialized server-side processing and significant administrative monitoring. XCode’s out-of-the-box Git integration enables steps 1 and 2 above.  Time Machine backups of the local repository add an additional degree of fault tolerance, but do not support collaboration or take advantage of managed infrastructure such as on-premises or cloud-based storage. Creating a Remote Repository These are the steps I use to enable the full workflow identified above.  For simplicity the “remote” repository is created on the local file system.  This location could easily be on a mounted network volume. Create a Test Project My project is called HelloGit and is located at /Users/Don/Dev/HelloGit.  Be sure to commit all outstanding changes.  XCode always leaves a single changed file for me after the project is created and the initial commit is submitted. Clone the Local Repository We want to clone the XCode-created Git repository to the location where the remote repository will reside.  In this case it will be /Users/Don/Dev/RemoteHelloGit. Open the Terminal application. Clone the local repository to the remote repository location: git clone /Users/Don/Dev/HelloGit /Users/Don/Dev/RemoteHelloGit Convert the Remote Repository to a Bare Repository The remote repository only needs to contain the Git database.  It does not need a checked out branch or local files. Go to the remote repository folder: cd /Users/Don/Dev/RemoteHelloGit Indicate the repository is “bare”: git config --bool core.bare true Remove files, leaving the .git folder: rm -R * Remove the “origin” remote: git remote rm origin Configure the Local Repository The local repository should reference the remote repository.  The remote name “origin” is used by convention to indicate the originating repository.  This is set automatically when a repository is cloned.  We will use the “origin” name here to reflect that relationship. Go to the local repository folder: cd /Users/Don/Dev/HelloGit Add the remote: git remote add origin /Users/Don/Dev/RemoteHelloGit Test Connectivity Any changes made to the local Git repository can be pushed to the remote repository subject to the merging rules Git enforces. Create a new local file: date > date.txt /li> Add the new file to the local index: git add date.txt Commit the change to the local repository: git commit -m "New file: date.txt" Push the change to the remote repository: git push origin master Now you can save, commit, and push/pull to your OCD hearts’ content! Code without fear! --Don

• Security and the Mobile Workforce

  - by tobyehatch

  Now that many organizations are moving to the BYOD philosophy (bring your own devices), security for phones and tablets accessing company sensitive information is of paramount importance. I had the pleasure to interview Brian MacDonald, Principal Product Manager for Oracle Business Intelligence (BI) Mobile Products, about this subject, and he shared some wonderful insight about how the Oracle Mobile Security Tool Kit is addressing mobile security and doing some pretty cool things.  With the rapid proliferation of phones and tablets, there is a perception that mobile devices are a security threat to corporate IT, that mobile operating systems are not secure, and that there are simply too many ways to inadvertently provide access to critical analytic data outside the firewall. Every day, I see employees working on mobile devices at the airport, while waiting for their airplanes, and using public WIFI connections at coffee houses and in restaurants. These methods are not typically secure ways to access confidential company data. I asked Brian to explain why. “The native controls for mobile devices and applications are indeed insufficiently secure for corporate deployments of Business Intelligence and most certainly for businesses where data is extremely critical - such as financial services or defense - although it really applies across the board. The traditional approach for accessing data from outside a firewall is using a VPN connection which is not a viable solution for mobile. The problem is that once you open up a VPN connection on your phone or tablet, you are creating an opening for the whole device, for all the software and installed applications. Often the VPN connection by itself provides insufficient encryption – if any – which means that data can be potentially intercepted.” For this reason, most organizations that deploy Business Intelligence data via mobile devices will only do so with some additional level of control. So, how has the industry responded? What are companies doing to address this very real threat? Brian explained that “Mobile Device Management (MDM) and Mobile Application Management (MAM) software vendors have rapidly created solutions for mobile devices that provide a vast array of services for controlling, managing and establishing enterprise mobile usage policies. On the device front, vendors now support full levels of encryption behind the firewall, encrypted local data storage, credential management such as federated single-sign-on as well as remote wipe, geo-fencing and other risk reducing features (should a device be lost or stolen). More importantly, these software vendors have created methods for providing these capabilities on a per application basis, allowing for complete isolation of the application from the mobile operating system. Finally, there are tools which allow the applications themselves to be distributed through enterprise application stores allowing IT organizations to manage who has access to the apps, when updates to the applications will happen, and revoke access after an employee leaves. So even though an employee may be using a personal device, access to company data can be controlled while on or near the company premises. So do the Oracle BI mobile products integrate with the MDM and MAM vendors? Brian explained that our customers use a wide variety of mobile security vendors and may even have more than one in-house. Therefore, Oracle is ensuring that users have a choice and a mechanism for linking together Oracle’s BI offering with their chosen vendor’s secure technology. The Oracle BI Mobile Security Toolkit, which is a version of the Oracle BI Mobile HD application, delivered through the Oracle Technology Network (OTN) in its component parts, helps Oracle users to build their own version of the Mobile HD application, sign it with their own enterprise development certificates, link with their security vendor of choice, then deploy the combined application through whichever means they feel most appropriate, including enterprise application stores.  Brian further explained that Oracle currently supports most of the major mobile security vendors, has close relationships with each, and maintains strong partnerships enabling both Oracle and the vendors to test, update and release a cooperating solution in lock-step. Oracle also ensures that as new versions of the Oracle HD application are made available on the Apple iTunes store, the same version is also immediately made available through the Security Toolkit on OTN.  Rest assured that as our workforce continues down the mobile path, company sensitive information can be secured.  To listen to the entire podcast, click here.

• You Probably Already Have a “Private Cloud”

  - by BuckWoody

  I’ve mentioned before that I’m not a fan of the word “Cloud”. It’s too marketing-oriented, gimmicky and non-specific. A better definition (in many cases) is “Distributed Computing”. That means that some or all of the computing functions are handled somewhere other than under your specific control. But there is a current use of the word “Cloud” that does not necessarily mean that the computing is done somewhere else. In fact, it’s a vector of Cloud Computing that can better be termed “Utility Computing”. This has to do with the provisioning of a computing resource. That means the setup, configuration, management, balancing and so on that is needed so that a user – which might actually be a developer – can do some computing work. To that person, the resource is just “there” and works like they expect, like the phone system or any other utility. The interesting thing is, you can do this yourself. In fact, you probably already have been, or are now. It’s got a cool new trendy term – “Private Cloud”, but the fact is, if you have your setup automated, the HA and DR handled, balancing and performance tuning done, and a process wrapped around it all, you can call yourself a “Cloud Provider”. A good example here is your E-Mail system. your users – pretty much your whole company – just logs into e-mail and expects it to work. To them, you are the “Cloud” provider. On your side, the more you automate and provision the system, the more you act like a Cloud Provider. Another example is a database server. In this case, the “end user” is usually the development team, or perhaps your SharePoint group and so on. The data professionals configure, monitor, tune and balance the system all the time. The more this is automated, the more you’re acting like a Cloud Provider. Lots of companies help you do this in your own data centers, from VMWare to IBM and many others. Microsoft's offering in this is based around System Center – they have a “cloud in a box” provisioning system that’s actually pretty slick. The most difficult part of operating a Private Cloud is probably the scale factor. In the case of Windows and SQL Azure, we handle this in multiple ways – and we're happy to share how we do it. It’s not magic, and the algorithms for balancing (like the one we started with called Paxos) are well known. The key is the knowledge, infrastructure and people. Sure, you can do this yourself, and in many cases such as top-secret or private systems, you probably should. But there are times where you should evaluate using Azure or other vendors, or even multiple vendors to spread your risk. All of this should be based on client need, not on what you know how to do already. So congrats on your new role as a “Cloud Provider”. If you have an E-mail system or a database platform, you can just put that right on your resume.

• Organization &amp; Architecture UNISA Studies &ndash; Chap 6

  - by MarkPearl

  Learning Outcomes Discuss the physical characteristics of magnetic disks Describe how data is organized and accessed on a magnetic disk Discuss the parameters that play a role in the performance of magnetic disks Describe different optical memory devices Magnetic Disk The way data is stored on and retried from magnetic disks Data is recorded on and later retrieved form the disk via a conducting coil named the head (in many systems there are two heads) The writ mechanism exploits the fact that electricity flowing through a coil produces a magnetic field. Electric pulses are sent to the write head, and the resulting magnetic patterns are recorded on the surface below with different patterns for positive and negative currents The physical characteristics of a magnetic disk   Summarize from book   The factors that play a role in the performance of a disk Seek time – the time it takes to position the head at the track Rotational delay / latency – the time it takes for the beginning of the sector to reach the head Access time – the sum of the seek time and rotational delay Transfer time – the time it takes to transfer data RAID The rate of improvement in secondary storage performance has been considerably less than the rate for processors and main memory. Thus secondary storage has become a bit of a bottleneck. RAID works on the concept that if one disk can be pushed so far, additional gains in performance are to be had by using multiple parallel components. Points to note about RAID… RAID is a set of physical disk drives viewed by the operating system as a single logical drive Data is distributed across the physical drives of an array in a scheme known as striping Redundant disk capacity is used to store parity information, which guarantees data recoverability in case of a disk failure (not supported by RAID 0 or RAID 1) Interesting to note that the increase in the number of drives, increases the probability of failure. To compensate for this decreased reliability RAID makes use of stored parity information that enables the recovery of data lost due to a disk failure.   The RAID scheme consists of 7 levels…   Category Level Description Disks Required Data Availability Large I/O Data Transfer Capacity Small I/O Request Rate Striping 0 Non Redundant N Lower than single disk Very high Very high for both read and write Mirroring 1 Mirrored 2N Higher than RAID 2 – 5 but lower than RAID 6 Higher than single disk Up to twice that of a signle disk for read Parallel Access 2 Redundant via Hamming Code N + m Much higher than single disk Highest of all listed alternatives Approximately twice that of a single disk Parallel Access 3 Bit interleaved parity N + 1 Much higher than single disk Highest of all listed alternatives Approximately twice that of a single disk Independent Access 4 Block interleaved parity N + 1 Much higher than single disk Similar to RAID 0 for read, significantly lower than single disk for write Similar to RAID 0 for read, significantly lower than single disk for write Independent Access 5 Block interleaved parity N + 1 Much higher than single disk Similar to RAID 0 for read, lower than single disk for write Similar to RAID 0 for read, generally  lower than single disk for write Independent Access 6 Block interleaved parity N + 2 Highest of all listed alternatives Similar to RAID 0 for read; lower than RAID 5 for write Similar to RAID 0 for read, significantly lower than RAID 5  for write   Read page 215 – 221 for detailed explanation on RAID levels Optical Memory There are a variety of optical-disk systems available. Read through the table on page 222 – 223 Some of the devices include… CD CD-ROM CD-R CD-RW DVD DVD-R DVD-RW Blue-Ray DVD Magnetic Tape Most modern systems use serial recording – data is lade out as a sequence of bits along each track. The typical recording used in serial is referred to as serpentine recording. In this technique when data is being recorded, the first set of bits is recorded along the whole length of the tape. When the end of the tape is reached the heads are repostioned to record a new track, and the tape is again recorded on its whole length, this time in the opposite direction. That process continued back and forth until the tape is full. To increase speed, the read-write head is capable of reading and writing a number of adjacent tracks simultaneously. Data is still recorded serially along individual tracks, but blocks in sequence are stored on adjacent tracks as suggested. A tape drive is a sequential access device. Magnetic tape was the first kind of secondary memory. It is still widely used as the lowest-cost, slowest speed member of the memory hierarchy.

• Need WIF Training?

  - by Your DisplayName here!

  I spend numerous hours every month answering questions about WIF and identity in general. This made me realize that this is still quite a complicated topic once you go beyond the standard fedutil stuff. My good friend Brock and I put together a two day training course about WIF that covers everything we think is important. The course includes extensive lab material where you take standard application and apply all kinds of claims and federation techniques and technologies like WS-Federation, WS-Trust, session management, delegation, home realm discovery, multiple identity providers, Access Control Service, REST, SWT and OAuth. The lab also includes the latest version of the thinktecture identityserver and you will learn how to use and customize it. If you are looking for an open enrollment style of training, have a look here. Or contact me directly! The course outline looks as follows: Day 1 Intro to Claims-based Identity & the Windows Identity Foundation WIF introduces important concepts like conversion of security tokens and credentials to claims, claims transformation and claims-based authorization. In this module you will learn the basics of the WIF programming model and how WIF integrates into existing .NET code. Externalizing Authentication for Web Applications WIF includes support for the WS-Federation protocol. This protocol allows separating business and authentication logic into separate (distributed) applications. The authentication part is called identity provider or in more general terms - a security token service. This module looks at this scenario both from an application and identity provider point of view and walks you through the necessary concepts to centralize application login logic both using a standard product like Active Directory Federation Services as well as a custom token service using WIF’s API support. Externalizing Authentication for SOAP Services One big benefit of WIF is that it unifies the security programming model for ASP.NET and WCF. In the spirit of the preceding modules, we will have a look at how WIF integrates into the (SOAP) web service world. You will learn how to separate authentication into a separate service using the WS-Trust protocol and how WIF can simplify the WCF security model and extensibility API. Day 2 Advanced Topics:  Security Token Service Architecture, Delegation and Federation The preceding modules covered the 80/20 cases of WIF in combination with ASP.NET and WCF. In many scenarios this is just the tip of the iceberg. Especially when two business partners decide to federate, you usually have to deal with multiple token services and their implications in application design. Identity delegation is a feature that allows transporting the client identity over a chain of service invocations to make authorization decisions over multiple hops. In addition you will learn about the principal architecture of a STS, how to customize the one that comes with this training course, as well as how to build your own. Outsourcing Authentication:  Windows Azure & the Azure AppFabric Access Control Service Microsoft provides a multi-tenant security token service as part of the Azure platform cloud offering. This is an interesting product because it allows to outsource vital infrastructure services to a managed environment that guarantees uptime and scalability. Another advantage of the Access Control Service is, that it allows easy integration of both the “enterprise” protocols like WS-* as well as “web identities” like LiveID, Google or Facebook into your applications. ACS acts as a protocol bridge in this case where the application developer doesn’t need to implement all these protocols, but simply uses a service to make it happen. Claims & Federation for the Web and Mobile World Also the web & mobile world moves to a token and claims-based model. While the mechanics are almost identical, other protocols and token types are used to achieve better HTTP (REST) and JavaScript integration for in-browser applications and small footprint devices. Also patterns like how to allow third party applications to work with your data without having to disclose your credentials are important concepts in these application types. The nice thing about WIF and its powerful base APIs and abstractions is that it can shield application logic from these details while you can focus on implementing the actual application. HTH

• Live CD has black screen HP DV6

  - by Shaun Killingbeck

  Attempting to install/try ubuntu (11.10, 12.04) on my new laptop, using a liveCD (and tried USB). I get the purple screen (with the man/keyboard at the bottom) and after that the screen flashes bright white before going black. Ubuntu continues to load in the background, with login sound etc but the screen is off. I have tried as many different solutions as I could find including: using nomodestep, xforcevesa, i915.modeset=0, and also now i915.modeset=1 in boot options (seperately): varying consequences, but either I end up at a blinking cursor with no prompt, a command line (startx fails: no screen found), or the original blank screen again Tried booting from VirtualBox - it crashes at the same place the screen would go blank when using a CD/USB tried 11.04: I don't have this problem BUT when trying to install, I get a ubi-partman error 141 (possibly down to the three partitions that came on my laptop... not sure why HP needed there own separate partition for HP Tools...) Model: HP Pavillion DV6 6B08SA Processor: AMD Quad-Core A6-3410MX APU with Radeon HD 6545G2 Dual Graphics (1.6 GHZ 4 MB L2 cache ) Chipset: AMD RS880M Any help would be greatly appreciated. I just want to be able to partition the drive and install Ubuntu. I'm assuming the issue is graphics card related, although I have no confirmation of that. Update: Tried the ?orkarounds on https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen - set gfxpayload=text changed nothing, removing splash did nothing and setting vesafb.nonsense=1 did nothing either. I'd like to be able to collect some log information somehow, but I can't get to a command line from the liveCD. tried using the latest 12.04 beta, same issue tried nomodeset without splash or quiet. get the following (tail of) output before it freezes on that screen: * Starting configure network device security [OK] * Starting configure network device [OK] [ 25.720899] ieee80211 phy0: w1_ops_config: change monitor mode: false (implement) [ 25.720923] ieee80211 phy0: w1_ops_config: change power-save mode: false (implement) * Starting restore sound card(s') mixer state(s) [fail] [ 25.721849] ieee80211 phy0: w1_ops_bss_info_changed: qos enabled: false (implement) * Stopping save kernel messages [OK] * Starting bluetooth [OK] * PulseAudio configured for per-user sessions saned disabled; edit /etc/default/saned [ 25.988016] hci_cmd_timer: hci0 command tx timeout [ 26.207225] bad LUN (0:1) [ 26.223735] bad target number (1:0) [ 26.252111] bad target number (2:0) [ 26.272170] bad target number (3:0) [ 26.300154] bad target number (4:0) [ 26.328162] bad target number (5:0) [ 26.344180] bad target number (6:0) [ 26.368142] bad target number (7:0) * Checking battery state...

The Pragmatic Architect: To Boldly Go Where No One Has Gone Before | Frank Buschmann "Many architects have technical knowledge that's both impressive and sound, which is indeed an inevitable basis for design success," says Frank Buschmann. "Yet, a lot of software projects fail or suffer due to severe challenges in their architecture. The key to mastery is how architects approach design, what they value, and where they focus their attention and work." As retail dies, whom will be the winners? | Peter Evans-Greenwood "The problem for many retailers is that how consumers shop has changed but the the retailers haven't adapted, " says Peter Evans-Greenwood. "Their sole virtue was to be the last step in a supply chain delivering somebody else's products to the consumer. However, being the last step in the supply chain is no longer a virtue when consumers skip across channels and can reach around the globe, no longer dependant on or limited to what they can find locally." Thought for the Day "Brains require stimulation. If you're locked into a pattern of work, work, and more work, your brain soon habituates - the same way that it lets you stop hearing a clock ticking. So, if you want to be more effective at work, you must, paradoxically, be less single-minded in your devotion to work. Anything you do—anything—that stimulates new segments of your brain will make you a more effective programmer or analyst. I promise, with a money-back guarantee." — Gerald M.

• How exactly is Google Webmaster Tools measuring "Site Performance"?

  - by Rémi

  I've been working for two months now on improving our response time (mainly server side) on a new forum (a brand new product on a technical point of view) we've launched in Germany a few month ago and I'm a lot surprised by the results I get. I monitor our response time using Apache logs and our own implementation of Boomerang beacon. Using my stats, I can see that our new product responds in about 680 ms where our old product was responding in about 1050 ms. On the other side, Google Webmaster Tool tells us that our pages have an average reponse time of about 1500 ms today where it was 700 three months ago with our old product. I've figured that GWT was taking client side metrics into account so I've added some measures on our Boomerang beacon and everything looks just fine. I've also ran some random pages on ySlow and Google's Page Speed and everything looks better than it was before. We event have a 82% on Google's Page Speed tool which is quite cool for a site with some ads in it :) Lately, we have signed a deal with Akamai to use two of their products : CDN for our static files (we were using another CDN before but it wasn't very effective) and RMA to improve Networks routes. We have also introduced a new agressive cache mecanism to ensure that most of the pages served to crawlers are cached by our memcache grid. After checking my metrics, it seems that this changes have improved from 650ms to about 500ms, which is good (still not great but it is definitly an improvement). But webmaster tools continues to report an increasing average response time where we see it decreasing in the same time. Have you ever had the same kind of wierd behavior on your sites while doing performance improvements ? Do you have any idea how to monitor the same thing Google does with Site Performance in Google Webmaster Tools so that we could improve our site and constantly check if it is what Google wants ? Edit 2011/07/26 : Thanks for your answers guys ! Nevertheless, I was not precise enough. The main issue we have is not with the Site Performance page but with the Crawl Stats one for now. We probably found an issue on our side with some very slow pages (around 3000 ms !!) and we are trying to fix them. I'll keep you posted as soon I'll have some infos. Thanks again !

• Memory read/write access efficiency

  - by wolfPack88

  I've heard conflicting information from different sources, and I'm not really sure which one to believe. As such, I'll post what I understand and ask for corrections. Let's say I want to use a 2D matrix. There are three ways that I can do this (at least that I know of). 1: int i; char **matrix; matrix = malloc(50 * sizeof(char *)); for(i = 0; i < 50; i++) matrix[i] = malloc(50); 2: int i; int rowSize = 50; int pointerSize = 50 * sizeof(char *); int dataSize = 50 * 50; char **matrix; matrix = malloc(dataSize + pointerSize); char *pData = matrix + pointerSize - rowSize; for(i = 0; i < 50; i++) { pData += rowSize; matrix[i] = pData; } 3: //instead of accessing matrix[i][j] here, we would access matrix[i * 50 + j] char *matrix = malloc(50 * 50); In terms of memory usage, my understanding is that 3 is the most efficient, 2 is next, and 1 is least efficient, for the reasons below: 3: There is only one pointer and one allocation, and therefore, minimal overhead. 2: Once again, there is only one allocation, but there are now 51 pointers. This means there is 50 * sizeof(char *) more overhead. 1: There are 51 allocations and 51 pointers, causing the most overhead of all options. In terms of performance, once again my understanding is that 3 is the most efficient, 2 is next, and 1 is least efficient. Reasons being: 3: Only one memory access is needed. We will have to do a multiplication and an addition as opposed to two additions (as in the case of a pointer to a pointer), but memory access is slow enough that this doesn't matter. 2: We need two memory accesses; once to get a char *, and then to the appropriate char. Only two additions are performed here (once to get to the correct char * pointer from the original memory location, and once to get to the correct char variable from wherever the char * points to), so multiplication (which is slower than addition) is not required. However, on modern CPUs, multiplication is faster than memory access, so this point is moot. 1: Same issues as 2, but now the memory isn't contiguous. This causes cache misses and extra page table lookups, making it the least efficient of the lot. First and foremost: Is this correct? Second: Is there an option 4 that I am missing that would be even more efficient?
