• Quick run through of the WP7 Developer Tools January 2011

  - by mbcrump

  In case you haven’t heard the latest WP7 Developers Tool update was released yesterday and contains a few goodies. First you need to go and grab the bits here. You can install them in any order, but I installed the WindowsPhoneDeveloperResources_en-US_Patch1.msp first. Then the VS10-KB2486994-x86.exe. They install silently. In other words, you would need to check Programs and Features and look in Installed Updates to see if they installed successfully. Like the screenshot below: Once you get them installed you can try out a few new features. Like Copy and Paste. Just fire up your application and put a TextBox on it and Select the Text and you will have the option highlighted in red above the text. Once you select it you will have the option to paste it. (see red rectangle below). Another feature is the Windows Phone Capability Detection Tool – This tool detects the phone capabilities used by your application. This will prevent you from submitting an app to the marketplace that says it uses x feature but really does not. How do you use it? Well navigate out to either directory: %ProgramFiles%\Microsoft SDKs\Windows Phone\v7.0\Tools\CapDetect %ProgramFiles (x86)%\Microsoft SDKs\Windows Phone\v7.0\Tools\CapDetect and run the following command: CapabilityDetection.exe Rules.xml YOURWP7XAPFILEOUTPUTDIRECTORY So, in my example you will see my app only requires the ID_CAP_MICROPHONE. Let’s see what the WmAppManifest.xml says in our WP7 Project: Whoa! That’s a lot of extra stuff we don’t need. We can delete unused capabilities safely now. Some of the other fixes are: (Copied straight from Microsoft) Fixes a text selection bug in pivot and panorama controls. In applications that have pivot or panorama controls that contain text boxes, users can unintentionally change panes when trying to copy text. To prevent this problem, open your application, recompile it, and then resubmit it to the Windows Phone Marketplace. Windows Phone Connect Tool – Allows you to connect your phone to a PC when Zune® software is not running and debug applications that use media APIs. For more information, see How to: Use the Connect Tool. Updated Bing Maps Silverlight Control – Includes improvements to gesture performance when using Bing™ Maps Silverlight® Control. Windows Phone Developer Tools Fix allowing deployment of XAP files over 64 MB in size to physical phone devices for testing and debugging. That’s pretty much it.

• Access Offline or Overloaded Webpages in Firefox

  - by Asian Angel

  What do you do when you really want to access a webpage only to find that it is either offline or overloaded from too much traffic? You can get access to the most recent cached version using the Resurrect Pages extension for Firefox. The Problem If you have ever encountered a website that has become overloaded and unavailable due to sudden popularity (i.e. Slashdot, Digg, etc.) then this is the result. No satisfaction to be had here… Resurrect Pages in Action Once you have installed the extension you can add the Toolbar Button if desired…it will give you the easiest access to Resurrect Pages. Or you can wait for a problem to occur when trying to access a particular website and have it appear as shown here. As you can see there is a very nice selection of cache services to choose from, therefore increasing your odds of accessing a copy of that webpage. If you would prefer to have the access attempt open in a new tab or window then you should definitely use the Toolbar Button. Clicking on the Toolbar Button will give you access to the popup window shown here…otherwise the access attempt will happen in the current tab. Here is the result for the website that we wanted to view using the Google Listing. Followed by the Google (text only) Listing. The results with the different services will depend on how recently the webpage was published/set up. View Older Versions of Currently Accessible Websites Just for fun we decided to try the extension out on the How-To Geek website to view an older version of the homepage. Using the Toolbar Button and clicking on The Internet Archive brought up the following page…we decided to try the Nov. 28, 2006 listing. As you can see things have really changed between 2006 and now…Resurrect Pages can be very useful for anyone who is interested in how websites across the web have grown and changed over the years. Conclusion If you encounter a webpage that is offline or overloaded by sudden popularity then the Resurrect Pages extension can help you get access to the information that you need using a cached version.

• How to interview a natural scientist for a dev position?

  - by Silas

  I already did some interviews for my company, mostly computer scientists for dev positions but also some testers and project managers. Now I have to fill a vacancy in our research group within the R&D department (side note: “research” means that we try to solve problems in our professional domain/market niche using software in research projects together with universities, other companies, research centres and end user organisations. It’s not computer science research; we’re not going to solve the P=NP problem). Now we invited a guy holding an MSc in chemistry (with a lot of physics in his CV, too), who never had any computer science lesson. I already talked with him about half an hour at a local university’s career days and there’s no doubt the guy is smart. Also his marks are excellent and he graduated with distinction. For his BSc he needed to teach himself programming in Mathematica and told me believably that he liked programming a lot. Also he solved some physical chemistry problem that I probably don’t understand using his own software, implemented in Mathematica, for his MSc thesis. It includes a GUI and a notable size of 8,000 LoC. He seems to be very attracted by what we’re doing in our research group and to be honest it’s quite difficult for an SME like us to get good people. I also am very interested in hiring him since he could assist me in writing project proposals, reports, doing presentations and so on. He would probably fit to our team, too. The only question left is: How can I check if he will get the programming skills he needs to do software implementation in our projects since this will be a significant part of the job? Of course I will ask him what it is, that is fascinating him about programming. I’ll also ask how he proceeded to write his natural science software and how he structured it. I’ll ask about how he managed to obtain the skills and information about software development he needed. But is there something more I could ask? Something more concrete perhaps? Should I ask him to explain his Mathematica solution? To be clear: I’m not looking for knowledge in a particular language or technology stack. We’re a .NET shop in product development but I want to have a free choice for our research projects. So I’m interested in the meta-competence being able to learn whatever is actually needed. I hope this question is answerable and not open-ended since I really like to know if there is a default way to check for the ability to get further programming skills on the job. If something is not clear to you please give me some comments and let me improve my question.

• Multiplayer tile based movement synchronization

  - by Mars

  I have to synchronize the movement of multiple players over the Internet, and I'm trying to figure out the safest way to do that. The game is tile based, you can only move in 4 directions, and every move moves the sprite 32px (over time of course). Now, if I would simply send this move action to the server, which would broadcast it to all players, while the walk key is kept being pressed down, to keep walking, I have to take this next command, send it to the server, and to all clients, in time, or the movement won't be smooth anymore. I saw this in other games, and it can get ugly pretty quick, even without lag. So I'm wondering if this is even a viable option. This seems like a very good method for single player though, since it's easy, straight forward (, just take the next movement action in time and add it to a list), and you can easily add mouse movement (clicking on some tile), to add a path to a queue, that's walked along. The other thing that came to my mind was sending the information that someone started moving in some direction, and again once he stopped or changed the direction, together with the position, so that the sprite will appear at the correct position, or rather so that the position can be fixed if it's wrong. This should (hopefully) only make problems if someone really is lagging, in which case it's to be expected. For this to work out I'd need some kind of queue though, where incoming direction changes and stuff are saved, so the sprite knows where to go, after the current movement to the next tile is finished. This could actually work, but kinda sounds overcomplicated. Although it might be the only way to do this, without risk of stuttering. If a stop or direction change is received on the client side it's saved in a queue and the char keeps moving to the specified coordinates, before stopping or changing direction. If the new command comes in too late there'll be stuttering as well of course... I'm having a hard time deciding for a method, and I couldn't really find any examples for this yet. My main problem is keeping the tile movement smooth, which is why other topics regarding synchronization of pixel based movement aren't helping too much. What is the "standard" way to do this?

• Can't boot Ubuntu 12.10 graphics problem

  - by Frantumn

  I can't boot since installing Ubuntu 12.10 When I try to run Ubuntu My computer never gets to the Ubuntu screen with the loading dots. I tried to run in recovery mode with safe graphics (failsafex) When I do this a message pops up saying "the system is running in low graphics mode", If I click okay I am asked what would I like to do and am given four options. I tried running low graphics for one session and then a message appears with a progress bar and says standby one minute while the display restarts. The progress bar never moves and if I click okay the whole process just restarts. I Don't know what to do from here I can't get into the OS. I'm not sure whether the problem is related to compatibility with my laptop monitor or my graphic card nvidia360m I had to install using a safe graphics mode. To learn about how I installed see this link. This link also has information on my computer hardware. Can't install Ubuntu since 10.10 ----UPDATE--- I was able to get into a desktop environment By installing Nvidia-current however it is messy. I have a screen and I am able to see my desktop however there is no unity bar and none of the keyboard controls work. I can right click and create a folder on the desktop and then I can see inside that folder in a traditional browser window. There is still no top menu or unity bar. When I boot normally I don't get into the desktop environment and I get this message in tty 'GPU lockup switching to software FBCON' Okay, I've played around with tips the pages from comments. I've been able to consistantly get into a safemode desktop environment using the xorg & nouveau drivers. I've tried switching between the 5 different options in the Additional Drivers tab in Software Sources. The nVidia (proprietary, tested) driver gets beyond the GPU lockup on a normal boot and actually gets into a Desktop. The issue is then that there is no Unity bar, or top screen menu bar and the resolution is very low. I've tried switching to the (prop, tested) driver and then reinstalling Unity and Ubuntu-Desktop but that didn't work either.

• Should EICAR be updated to test the revision of Antivirus system?

  - by makerofthings7

  I'm posting this here since programmers write viruses, and AV software. They also have the best knowledge of heuristics and how AV systems work (cloaking etc). The EICAR test file was used to functionally test an antivirus system. As it stands today almost every AV system will flag EICAR as being a "test" virus. For more information on this historic test virus please click here. Currently the EICAR test file is only good for testing the presence of an AV solution, but it doesn't check for engine file or DAT file up-to-dateness. In other words, why do a functional test of a system that could have definition files that are more than 10 years old. With the increase of zero day threats it doesn't make much sense to functionally test your system using EICAR. That being said, I think EICAR needs to be updated/modified to be effective test that works in conjunction with an AV management solution. This question is about real world testing, without using live viruses... which is the intent of the original EICAR. That being said I'm proposing a new EICAR file format with the appendage of an XML blob that will conditionally cause the Antivirus engine to respond. X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-EXTENDED-ANTIVIRUS-TEST-FILE!$H+H* <?xml version="1.0"?> <engine-valid-from>2010-1-1Z</engine-valid-from> <signature-valid-from>2010-1-1Z</signature-valid-from> <authkey>MyTestKeyHere</authkey> In this sample, the antivirus engine would only alert on the EICAR file if both the signature or engine file is equal to or newer than the valid-from date. Also there is a passcode that will protect the usage of EICAR to the system administrator. If you have a backgound in "Test Driven Design" TDD for software you may get that all I'm doing is applying the principals of TDD to my infrastructure. Based on your experience and contacts how can I make this idea happen?

• Simple thruster like behaviour when rotating sprite

  - by ensamgud

  I'm prototyping some 2D game concepts with XNA and have added some basic keyboard inputs to control a triangle sprite. When I press key up the sprite accelerates in it's current facing direction, when I release the key it brakes down. For rotation, when I press left/right keys I rotate the sprite. Currently the sprite immedately changes direction when I rotate it. What I want is for it to keep moving in the same direction when I rotate, until I hit key up, adding thrust in whatever direction the sprite is pointing at. This would simulate thrusters on a classic space shooter like Asteroids. I'm adding an image to describe the behaviour I'm after and some code samples of how I'm doing things at the moment. This is my player struct, holding information of the sprite. public struct PlayerData { public Vector2 Position; // where to draw the sprite public Vector2 Direction; // travel direction of sprite public float Angle; // rotation of sprite public float Velocity; public float Acceleration; public float Decelleration; public float RotationAcceleration; public float RotationDecceleration; public float TopSpeed; public float Scale; } This is how I'm currently handling thrusting / braking (when pressing/releasing key up) (simplified, removed some bounds checking etc): player.Velocity += player.Acceleration * 0.1f; player.Velocity -= player.Acceleration * 0.1f; And when I rotate the sprite left and right: player.Angle -= player.RotationAcceleration * 0.1f; player.Angle += player.RotationAcceleration * 0.1f; This runs in the update loop, keeps the direction updated and updates the position: Vector2 up = new Vector2(0f, -1f); Matrix rotMatrix = Matrix.CreateRotationZ(player.Angle); player.Direction = Vector2.Transform(up, rotMatrix); player.Direction *= player.Velocity; player.Position += player.Direction; I am following along various beginner tutorials and haven't found any describing this, but I have tried some on my own without success. Do I need to change my velocity and acceleration fields to Vectors instead of floats to accomplish this type of movement? I realise my Angle and the Direction vector is currently tied together and I need to disconnect these somehow to be able to rotate freely without changing the direction of the movement, but I can't quite figure out how to do this while keeping the acceleration/decceleration functional. Would appreciate an explanation rather than pure code samples. Thanks,

• Getting started with object detection - Image segmentation algorithm

  - by Dev Kanchen

  Just getting started on a hobby object-detection project. My aim is to understand the underlying algorithms and to this end the overall accuracy of the results is (currently) more important than actual run-time. I'm starting with trying to find a good image segmentation algorithm that provide a good jump-off point for the object detection phase. The target images would be "real-world" scenes. I found two techniques which mirrored my thoughts on how to go about this: Graph-based Image Segmentation: http://www.cs.cornell.edu/~dph/papers/seg-ijcv.pdf Contour and Texture Analysis for Image Segmentation: http://www.eng.utah.edu/~bresee/compvision/files/MalikBLS.pdf The first one was really intuitive to understand and seems simple enough to implement, while the second was closer to my initial thoughts on how to go about this (combine color/intensity and texture information to find regions). But it's an order of magnitude more complex (at least for me). My question is - are there any other algorithms I should be looking at that provide the kind of results that these two, specific papers have arrived at. Are there updated versions of these techniques already floating around. Like I mentioned earlier, the goal is relative accuracy of image segmentation (with an eventual aim to achieve a degree of accuracy of object detection) over runtime, with the algorithm being able to segment an image into "naturally" or perceptually important components, as these two algorithms do (each to varying extents). Thanks! P.S.1: I found these two papers after a couple of days of refining my search terms and learning new ones relevant to the exact kind of techniques I was looking for. :) I have just about reached the end of my personal Google creativity, which is why I am finally here! Thanks for the help. P.S.2: I couldn't find good tags for this question. If some relevant ones exist, @mods please add them. P.S.3: I do not know if this is a better fit for cstheory.stackexchange (or even cs.stackexchange). I looked but cstheory seems more appropriate for intricate algorithmic discussions than a broad question like this. Also, I couldn't find any relevant tags there either! But please do move if appropriate.

• Certification Notes: 70-583 Designing and Developing Windows Azure Applications

  - by BuckWoody

  Last Updated: 02/01/2011 It’s time for another certification, and we’ve just release the 70-583 exam on Windows Azure. I’ve blogged my “study plans” here before on other certifications, so I thought I would do the same for this one. I’ll also need to take exam 70-513 and 70-516; but I’ll post my notes on those separately. None of these are “brain dumps” or any questions from the actual tests - just the books, links and notes I have from my studies. I’ll update these references as I’m studying, so bookmark this site and watch my Twitter and Facebook posts for when I’ll update them, or just subscribe to the RSS feed. A “Green” color on the check-block means I’ve done that part so far, red means I haven’t. First, I need to refresh my memory on some basic coding, so along with the Azure-specific information I’m reading the following general programming books: Introducing Microsoft .NET (Pro-Developer): link   Head First C#, 2E: A Learner's Guide to Real-World Programming with Visual C# and .NET: link Microsoft Visual C# 2008 Step by Step: link  c The first place to start is at the official site for the certification. link c On that page you’ll find several resources, and the first you should follow is the “Save to my learning” so you have a place to track everything. Then click the “Related Learning Plans” link and follow the videos and read the documentation in each of those bullets. There are six areas on the learning plan that you should focus on - make sure you open the learning plan to drill into the specifics. c Designing Data Storage Architecture (18%) Books I’m Reading: Links: My Notes: c Optimizing Data Access and Messaging (17%) Books I’m Reading: Links: My Notes: c Designing the Application Architecture (19%) Books I’m Reading: Applied Architecture Patterns on the Microsoft Platform: link Links: My Notes: c Preparing for Application and Service Deployment (15%) Books I’m Reading: Links: My Notes: c Investigating and Analyzing Applications (16%) Books I’m Reading: Links: My Notes: c Designing Integrated Solutions (15%) Books I’m Reading: Applied Architecture Patterns on the Microsoft Platform (2nd mention) Links: My Notes:

• How to make sprint planning fun

  - by Jacob Spire

  Not only are our sprint planning meetings not fun, they're downright dreadful. The meetings are tedious, and boring, and take forever (a day, but it feels like a lot longer). The developers complain about it, and dread upcoming plannings. Our routine is pretty standard (user story inserted into sprint backlog by priority story is taken apart to tasks tasks are estimated in hours repeat), and I can't figure out what we're doing wrong. How can we make the meetings more enjoyable? ... Some more details, in response to requests for more information: Why are the backlog items not inserted and prioritized before sprint kickoff? User stories are indeed prioritized; we have no idea how long they'll take until we break them down into tasks! From the (excellent) answers here, I see that maybe we shouldn't estimate tasks at all, only the user stories. The reason we estimate tasks (and not stories) is because we've been getting story-estimates terribly wrong -- but I guess that's the subject for an altogether different question. Why are developers complaining? Meetings are long. Meetings are monotonous. Story after story, task after task, struggling (yes, struggling) to estimate how long it will take and what it involves. Estimating tasks makes user-story-estimation seem pointless. The longer the meeting, the less focus in the room. The less focused colleagues are, the longer the meeting takes. A recursive hate-spiral develops. We've considered splitting the meeting into two days in order to keep people focused, but the developers wouldn't hear of it. One day of planning is bad enough; now we'll have two?! Part of our problem is that we go into very small detail (in order to get more accurate estimations). But when we estimate roughly, we go way off the mark! To sum up the question: What are we doing wrong? What additional ways are there to make the meeting generally more enjoyable?

[30 mins] Getting Value from Big Data Variety Richard Tomlinson, Director, Product Management, Oracle Big data variety implies big data complexity. Performing analytics on diverse data typically involves mashing up structured, semi-structured and unstructured content. So how can we do this effectively to get real value? How do we relate diverse content so we can start to analyze it? This session looks at how we approach this tricky problem using Endeca Information Discovery. [30 mins] How To Leverage Your Investment In Oracle Business Intelligence Enterprise Edition Within a Big Data Architecture Oracle ACE Director Kevin McGinley More and more organizations are realizing the value Big Data technologies contribute to the return on investment in Analytics. But as an increasing variety of data types reside in different data stores, organizations are finding that a unified Analytics layer can help bridge the divide in modern data architectures. This session will examine how you can enable Oracle Business Intelligence Enterprise Edition (OBIEE) to play a role in a unified Analytics layer and the benefits and use cases for doing so. [30 mins] Oracle Data Integrator 12c As Your Big Data Data Integration Hub Oracle ACE Director Mark Rittman Oracle Data Integrator 12c (ODI12c), as well as being able to integrate and transform data from application and database data sources, also has the ability to load, transform and orchestrate data loads to and from Big Data sources. In this session, we'll look at ODI12c's ability to load data from Hadoop, Hive, NoSQL and file sources, transform that data using Hive and MapReduce processing across the Hadoop cluster, and then bulk-load that data into an Oracle Data Warehouse using Oracle Big Data Connectors. We will also look at how ODI12c enables ETL-offloading to a Hadoop cluster, with some tips and techniques on real-time capture into a Hadoop data reservoir and techniques and limitations when performing ETL on big data sources.

• Check if an object is facing another based on angles

  - by Isaiah

  I already have something that calculates the bearing angle to get one object to face another. You give it the positions and it returns the angle to get one to face the other. Now I need to figure out how tell if on object is facing toward another object within a specified field and I can't find any information about how to do this. The objects are obj1 and obj2. Their angles are at obj1.angle and obj2.angle. Their vectors are at obj1.pos and obj2.pos. It's in the format [x,y]. The angle to have one face directly at another is found with direction(obj1.pos,obj2.pos). I want to set the function up like this: isfacing(obj1,obj2,area){...} and return true/false depending if it's in the specified field area to the angle to directly see it. I've got a base like this: var isfacing = function (obj1,obj2,area){ var toface = direction(obj1.pos,obj2.pos); if(toface+area >= obj1.angle && ob1.angle >= toface-area){ return true; } return false; } But my problem is that the angles are in 360 degrees, never above 360 and never below 0. How can I account for that in this? If the first object's angle is say at 0 and say I subtract a field area of 20 or so. It'll check if it's less than -20! If I fix the -20 it becomes 340 but x < 340 isn't what I want, I'd have to x 340 in that case. Is there someone out there with more sleep than I that can help a new dev pulling an all-nighter just to get enemies to know if they're attacking in the right direction? I hope I'm making this harder than it seems. I'd just make them always face the main char if the producer didn't want attacks from behind to work while blocking. In which case I'll need the function above anyways. I've tried to give as much info as I can think would help. Also this is in 2d.

• High CPU load for 1:30 minutes when mounting ext4-raid partition

  - by sirion

  I have a raid 5 (software) with 5x2TB drives. I encrypted the raid with cryptsetup and put an ext4-partition on top. In the beginning opening and mounting the raid took less than 10 seconds, now (for a few weeks) mounting alone takes 1:30 minutes and the cpu stays around 93% the whole time: The output of "time sudo mount /dev/mapper/8000 /media/8000" is: real 1m31.952s user 0m0.008s sys 1m25.229s At the same time only one line is added to /var/log/syslog: kernel: [ 2240.921381] EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null) My Ubuntu-version is "12.04.1 LTS" and no updates are pending. I checked the partition with fsck, but it says that all is ok. The "cryptsetup luksOpen" command only takes a few seconds. I also tried changing the raid-bitmap (as it was suggested in some forum) but it did not change the behaviour. sudo mdadm --grow /dev/md0 -b internal and sudo mdadm --grow /dev/md0 -b none I had the idea that it might be the hardware being slow, but a read test with "sudo hdparm -t /dev/md0" spit out values between 62 and 159 MB/sec: Timing buffered disk reads: 382 MB in 3.00 seconds = 127.14 MB/sec Timing buffered disk reads: 482 MB in 3.02 seconds = 159.62 MB/sec Timing buffered disk reads: 190 MB in 3.03 seconds = 62.65 MB/sec Timing buffered disk reads: 474 MB in 3.02 seconds = 157.12 MB/sec Although I think it is strange that the read rate jumps by more than 100% - could that mean something? The speed test when reading from the mapped (decrypted) device shows similar behavior, although it is of course much slower. "sudo hdparm -t /dev/mapper/8000": Timing buffered disk reads: 56 MB in 3.02 seconds = 18.54 MB/sec Timing buffered disk reads: 122 MB in 3.09 seconds = 39.43 MB/sec Timing buffered disk reads: 134 MB in 3.02 seconds = 44.35 MB/sec The output of a verbose mount "mount -vvv /dev/mapper/8000 /media/8000" does not help much: mount: fstab path: "/etc/fstab" mount: mtab path: "/etc/mtab" mount: lock path: "/etc/mtab~" mount: temp path: "/etc/mtab.tmp" mount: UID: 0 mount: eUID: 0 mount: spec: "/dev/mapper/8000" mount: node: "/media/8000" mount: types: "(null)" mount: opts: "(null)" mount: you didn't specify a filesystem type for /dev/mapper/8000 I will try type ext4 mount: mount(2) syscall: source: "/dev/mapper/8000", target: "/media/8000", filesystemtype: "ext4", mountflags: -1058209792, data: (null) Any idea where I could find additional information on why mounting takes so long, or what additional tests I could run?

• Survey: Your Plans for Adopting New Firefox Releases?

  - by Steven Chan (Oracle Development)

  Mozilla is committing to releasing new Firefox versions every six weeks.  Mozilla released Firefox 5 this week.  With this release, Mozilla states that Firefox 4 is End-of-Life and will not receive any additional security updates.  In a comment thread posted on to a Mike Kaply's blog article discussing these new Firefox policies, Asa Dotzler from Mozilla stated: ... Enterprise has never been (and I’ll argue, shouldn’t be) a focus of ours. Until we run out of people who don’t have sysadmins and enterprise deployment teams looking out for them, I can’t imagine why we’d focus at all on the kinds of environments you care so much about.  In a later comment, he added: ... A minute spent making a corporate user happy can better be spent making many regular users happy. I’d much rather Mozilla spending its limited resources looking out for the billions of users that don’t have enterprise support systems already taking care of them. Asa then confirmed that every new Firefox release will put the previous one into End-of-Life: As for John’s concern, “By the time I validate Firefox 5, what guarantee would I have that Firefox 5 won’t go EOL when Firefox 6 is released?” He has the opposite of guarantees that won’t happen. He has my promise that it will happen. Firefox 6 will be the EOL of Firefox 5. And Firefox 7 will be the EOL for Firefox 6.  He added: “You’re basically saying you don’t care about corporations.” Yes, I’m basically saying that I don’t care about making Firefox enterprise friendly. Kev Needham, Channel Manager at Mozilla later stated to PC Mag: The Web and Web browsers continue to evolve rapidly. Mozilla's focus is on providing users with the best Web experience possible, and Firefox needs to evolve at the pace the Web's users and developers expect. By releasing small, focused updates more often, we are able to deliver improved security and stability even as we introduce new features, which is better for our users, and for the Web.We recognize that this shift may not be compatible with a large organization's IT Policy and understand that it is challenging to organizations that have effort-intensive certification polices. However, our development process is geared toward delivering products that support the Web as it is today, while innovating and building future Web capabilities. Tying Firefox product development to an organizational process we do not control would make it difficult for us to continue to innovate for our users and the betterment of the Web.  Your feedback needed for E-Business Suite certifications  Mozilla's new support policy has significant implications for enterprise users of Firefox with Oracle E-Business Suite.  We are reviewing the implications for our certification and support policies for Firefox now.  It would be very helpful if you could let me know about your organisation's plans for Firefox in light of this new information.  Please feel free to drop me a private email, or post a comment here if that's appropriate.

• Office 2010 Professional Plus (Top 10 reasons to upgrade)

  - by mbcrump

  Being a huge nerd, I decided that I would go ahead and upgrade to the latest and greatest office. That being, Office 2010 Professional Plus. The biggest concern that I had was loosing all my mail settings from Outlook 2007. Thankfully, it upgrade gracefully and worked like a charm. So lets start this top 10 list. 1) You can upgrade without fear of loosing all your stuff! As you can tell by the screenshot below, you can select what you want to do. I selected to remove all previous versions.    2) Outlook conversations: Just like GMail, you can now group emails by conversations. This is simply awesome and a must have. 3) The ability to ignore conversations. If you are on a email thread that has nothing to do with you. Simply “ignore” the conversation and all emails go into the deleted folder. 4) Quick Steps, do you send an email to the same team member or group constantly. With quick steps, its just one click away. 5) Spell check in the Subject line! 6)  Easier Screenshots, built in just click the button. No more ALT-Printscreen for those that are not aware of the awesome SnagIT 10 that's out. 7) Open in protected view. When you open a document from an email attachment, it lets you know the file may be unsafe. You can click a button to enable editing. This is great for preventing macros.       8) Excel has always had a variety of charts and graphs available to visually depict data and trends. With Excel 2010, though, Microsoft has added a new feature called Sparklines, which allows you to place a mini-graph or trend line in a single cell. The Sparklines are a cool way to quickly and simply add a visual element without having to go through the effort of inserting a graph or chart that overwhelms the worksheet. 9) Contact actions. If you hover over a name in the form or fields on an email, you get a popup giving you several actions you can perform on the person such as adding them to your Outlook contacts, scheduling a meeting, viewing their stored contact information if they are already in your contacts, sending an instant message or even starting a telephone call. 10) Windows 7 Task Bar Context Menu – I love the jumplist. I don’t know how much that I would actually use it but it just rocks.

• Brocken package manager due to incorrect Banshee package

  - by user54974

  Sup, so, I'm not familiar with linux at all so help is much appreciated. I've been trying to boot my pc up from a live CD unsuccessfully. I get to the stage at which there are the options to test without installing or install or so on where I select 'Install Ubuntu.' Here it relays through some fast DOS commands until it reaches 'end trace' and then, eventually, 'Killed.' I have already got a functional 11.10 version installed, could this be a problem? The reason I am attempting a reinstall is because the package system is damaged inside 11.10, a problem I can't seem to solve. If I try to install any new software from within the software centre it tells me that two banshee extensions must be removed. I try to remove these from inside the terminal, using apt-get remove, which results in:** You might want to run apt-get -f install to correct these: The following packages have unmet dependencies. banshee-extension-ubuntuonemusicstore : Depends: banshee (>= 2.2.1) but 2.2.0-1ubuntu2 is to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). The software centre suggests that I disable all third party repositories and run apt-get install -f I have done so but the package system remains damaged and apt-get install -fattempts to install banshee 2.2.1 but returns: Errors were encountered while processing: /var/cache/apt/archives/banshee_2.2.1-1ubuntu3_i386.deb E: Sub-process /usr/bin/dpkg returned an error code (1) I have also tried apt-get update (runs fine) and apt-get upgrade. The upgrade command apt-get upgrade results in: Reading package lists... Done Building dependency tree Reading state information... Done You might want to run ‘apt-get -f install’ to correct these. The following packages have unmet dependencies. banshee-extension-soundmenu : Depends: banshee (>= 2.2.1) but 2.2.0-1ubuntu2 is installed banshee-extension-ubuntuonemusicstore : Depends: banshee (>= 2.2.1) but 2.2.0-1ubuntu2 is installed E: Unmet dependencies. Try using -f. I seem to be going round and round in circles here! If only I could reinstall successfully. Only proposed updates (oneiric proposed) is not enabled.

• Segmentation and Targeting: Your Tools for Personalizing the Online Customer Experience

  - by Christie Flanagan

  In order to deliver the kind of personalized and engaging online experiences that customers expect today, look to segmentation and targeting.  Segmentation is the practice of dividing your site visitors into distinct groups based on shared characteristics or behavior – for example, a segment may consist of site visitors who have visited pages related to certain product type, or they may consist of visitors within the same age group or geographic area.  The idea is that those within a segment are more likely to have common needs, problems or interests that can be served by your business. Targeting is the process by which the most relevant content, whether an article promotion or other piece of content, is delivered to your visitors based on their segment membership. Segmentation and targeting are used to drive greater engagement on your web presence by delivering content to your site visitors that is tailored to their interests, behavior or other attributes.  You may have a number of different goals for your segmentation and targeting efforts: Up-sell or cross-sell to your customers Conduct A/B testing on your offers and creative Offer discounts, promotions or other incentives for the time and duration that you specify Make is easier to find relevant information about products and services Create premium content model There are two different approaches you can take toward segmentation and targeting for you online customer experience initiatives. The first is more of a manual process, in which marketers manage the process of determining which segments to create and which content to target to those segments. The benefit of this approach is that it gives marketers a high level of control over the whole process which works well when you have a thorough understanding of your segments and which content is most likely to serve their needs.  Tools for marketer managed segmentation and targeting are often built right in to your WEM platform, as they are with Oracle WebCenter Sites. The downside is that the more segments and content that you have, the more time consuming and complicated in can be to manage manually.The second approach relies on predictive intelligence to automate the segmentation and targeting process.  This allows optimization of the process to occur in real time. This approach helps reduce the burden of manual segmentation and targeting and can result in new insights into segments that you may never have thought of on your own.  It also provides you with the capability to quickly test new offers and promotions on your site.  Predictive segmentation and targeting can be achieved by using Oracle WebCenter Sites and Oracle Real-Time Decisions together. *****Get a taste for how Oracle WebCenter Sites and Oracle Real-Time Decisions combine to deliver powerful capabilities for predictive segmentation and targeting by watching this on demand webcast introducing Oracle WebCenter Sites 11g or by reading IDC’s take on the latest release of Oracle’s web experience management solution.  Be sure to return to the Oracle WebCenter blog on Thursday for a closer look at how to optimize the online customer experience using these two products together.

• Cloud Infrastructure has a new standard

  - by macoracle

  I have been working for more than two years now in the DMTF working group tasked with creating a Cloud Management standard. That work has culminated in the release today of the Cloud Infrastructure Management Interface (CIMI) version 1.0 by the DMTF. CIMI is a single interface that a cloud consumer can use to manage their cloud infrastructure in multiple clouds. As CIMI is adopted by the cloud vendors, no more will you need to adapt client code to each of the proprietary interfaces from these multiple vendors. Unlike a de facto standard where typically one vendor has change control over the interface, and everyone else has to reverse engineer the inner workings of it, CIMI is a de jure standard that is under change control of a standards body. One reason the standard took two years to create is that we factored in use cases, requirements and contributed APIs from multiple vendors. These vendors have products shipping today and as a result CIMI has a strong foundation in real world experience. What does CIMI allow? CIMI is both a model for the resources (computing, storage networking) in the cloud as well as a RESTful protocol binding to HTTP. This means that to create a Machine (guest VM) for example, the client creates a “document” that represents the Machine resource and sends it to the server using HTTP. CIMI allows the resources to be encoded in either JavaScript Object Notation (JSON) or the eXentsible Markup Language (XML). CIMI provides a model for the resources that can be mapped to any existing cloud infrastructure offering on the market. There are some features in CIMI that may not be supported by every cloud, but CIMI also supports the discovery of which features are implemented. This means that you can still have a client that works across multiple clouds and is able to take full advantage of the features in each of them. Isn’t it too early for a standard? A key feature of a successful standard is that it allows for compatible extensions to occur within the core framework of the interface itself. CIMI’s feature discovery (through metadata) is used to convey to the client that additional features that may be vendor specific have been implemented. As multiple vendors implement such features, they become candidates to add the future versions of CIMI. Thus innovation can continue in the cloud space without being slowed down by a lowest common denominator type of specification. Since CIMI was developed in the open by dozens of stakeholders who are already implementing infrastructure clouds, I expect to CIMI being adopted by these same companies and others over the next year or two. Cloud Customers who can see the benefit of this standard should start to ask their cloud vendors to show a CIMI implementation in their roadmap.  For more information on CIMI and the DMTF's other cloud efforts, go to: http://dmtf.org/cloud

• SharePoint Thoughts

  - by Tim Murphy

  I was listening to .NET Rocks episode #713 and it got me thinking about a number of SharePoint related topics. I have been working with SharePoint since the 2001 product came out and have watched it evolve over the years.  Today SharePoint is one of the most powerful and flexible products in the market.  Of course that doesn’t mean there isn’t room for improvement (a lot of improvement in fact) and with much power comes much responsibility. My main gripe these days is that you have to develop on a server instance.  This adds a real barrier to entry for developers.  You either have to run VMWare or Hyper-V on your developer machine or actually develop on your dev server for most tasks.  Yes, there is a way to setup a Windows 7 machine with the SharePoint components but it is very hackish. Beyond that the tools in VS2010 are a great leap forward from past generations.  Not requiring a separate package creation tool is not the least of the improvements.  Better workflow and web part development have also eased the burden of many developers. The other thing the show brought up in my thoughts was more around usage.  Users want to be able to self server everything without regard to what affect that has on leveraging their data from a corporate perspective.  My coworkers who work on Lotus Notes ask why the user can’t just do what ever they want? Part of the reason is that those features have not been built, but the other part is that giving them those features is often like giving an infant a loaded hand gun.  You can do it but it doesn’t make it the smart thing to do. As with any tool that is going to be used in the enterprise it should be subject to governance.  If controls are not in place as they said in the episode of DNR the document libraries and I believe SharePoint in general starts to look as disarrayed and unusable as a shared drive.  Consider these factors before giving into every whim of the users.  You should be able to explain to them the tradeoffs of giving them full control versus being able to leverage the information they collect to the benefit of the organization. These are just a couple of the thoughts that were triggered by the show.  I’m sure there are more discussions that can be had.  Feel free to leave your comments about the pros and cons of SharePoint. del.icio.us Tags: .NET Rocks,SharePoint,software development

• What HTML and CSS markup is best for SEO for a list of questions (like on Stack Exchange sites)

  - by Oleg9

  On the StackOverflow a question block (in the q-list on the index page and so on) represented by the following html code: <div class="question-summary narrow tagged-interesting" id="question-summary-19832613"> <div onclick="window.location.href='/questions/19832613/how-to-display-only-transit-routesfor-trains-in-google-maps-api'" class="cp"> <div class="votes"> <div class="mini-counts">0</div> <div>votes</div> </div> <div class="status unanswered"> <div class="mini-counts">0</div> <div>answers</div> </div> <div class="views"> <div class="mini-counts">3</div> <div>views</div> </div> </div> <div class="summary"> <h3>...</h3> <div class="tags t-javascript t-google-maps t-google t-google-maps-api-3"> </div> <div class="started"> <a href="/questions/19832613/how-to-display-only-transit-routesfor-trains-in-google-maps-api" class="started-link"><span title="2013-11-07 09:52:29Z" class="relativetime">1 min ago</span></a> <a href="/users/1309392/shirish">Shirish</a> <span class="reputation-score" title="reputation score " dir="ltr">189</span> </div> </div> </div> It uses float positioning. My questions is: Would use of css styled tables be a better choice? (It's a table, isn't it?) Or it just depends on what are you prefer to use and doesn't affect the technical side (search engines or something)? The background information (such as number of views, votes etc.) comes first in the code. And I know that search engines have a limit at viewing each page. So would it better to place div's depending on their importance and then markup them on the page using css methods (like negative margins and absolute positioning)? Or it isn't so important in this instance?
