• Building a personal website using Silverlight.

  - by mbcrump

  I’ve always believed that as a developer you should always have a hobby project going on. I think a hobby project needs to contain at least one of following things: Something that you have never done before. Something that you are interested in. Something that you can work on in your spare time without affecting your *paying* job. I decided my hobby project would be an entire web application written in Silverlight that could be used as a self-promotion/marketing tool. This goal of the site is to provide information on the work that I’ve done to conferences, future employers and anyone else that wanted to learn more about me. Before I go any further, if you just want to check out the site then it is located at http://michaelcrump.info. So, what did I use to create it? MVVM Light – I’m a big fan of this software. The item and project templates plus code snippets make this a huge win for any SL/WPF/WP7 application. Jetpack Theme by Microsoft – I suck at designing so I used this template to help speed up this project. ComponentOne 3rd Party Controls – I have a license and really like several of their products. A User Control that Jeremy Likness created called DynamicXaml (used with his permission). I had created my own version of this a while back, but Jeremy’s implementation was simply better. Main Page – Designed to create my “brand”. This was built for a quick glimpse of who I am and what do I do.  Blog – The best marketing tool for a developer is their blog. I decided to go with an HTML page displaying my site and the user could pop into full-screen if desired. I also included my feed and Silverlight-Zone. (Another site I work on) Online – This page links to sites that I have been featured on as well as community involvement and awards. I also have a web service that I can update this information without re-compiling the Silverlight App. Projects – I’ve been wanting to use a CoverFlow for a really long time now. =) This page list several hobby projects as well as a few professional projects.  Resume Page – This page only exist because I got tired of sending companies my resume in e-mail. I can now provide a deep link to this page and the recruiter can print, search or save my resume. The PDF of my resume exist in a folder that I can easily update without recompiling the app. Contact Page – Just a contact page with a web service that sends the email. The Send button becomes disabled after a successful send. I thought of adding captcha to this page but in the end didn’t think it was worth it. Looking back at this app, I’m happy with how it turned out. I love Silverlight and I am already thinking of my next hobby project. (Thinking another Windows Phone 7 app or MVC3).  Subscribe to my feed

• What's a good entity hierarchy for a 2D game?

  - by futlib

  I'm in the process of building a new 2D game out of some code I wrote a while ago. The object hierarchy for entities is like this: Scene (e.g. MainMenu): Contains multiple entities and delegates update()/draw() to each Entity: Base class for all things in a scene (e.g. MenuItem or Alien) Sprite: Base class for all entities that just draw a texture, i.e. don't have their own drawing logic Does it make sense to split up entities and sprites up like that? I think in a 2D game, the terms entity and sprite are somewhat synonymous, right? But I do believe that I need some base class for entities that just draw a texture, as opposed to drawing themselves, to avoid duplication. Most entities are like that. One weird case is my Text class: It derives from Sprite, which accepts either the path of an image or an already loaded texture in its constructor. Text loads a texture in its constructor and passes that to Sprite. Can you outline a design that makes more sense? Or point me to a good object-oriented reference code base for a 2D game? I could only find 3D engine code bases of decent code quality, e.g. Doom 3 and HPL1Engine.

DevOps is a response to the interdependence of software development and IT operations. It aims to help an organization rapidly produce software products and services. That definition of DevOps is the – what. The “why” is even easier. Standardized development methodology, clear communication and documented processes supported by a standards-based, proven middleware platform improves application development and management cycles, brings agility and provides greater availability and security to your IT infrastructure. Clearly, DevOps is about connecting people, products and processes. Ultimately, DevOps is about connecting IT to business.

• Is there any site which tells or highlights by zone developer income source? I think i am getting less yearly [closed]

  - by YumYumYum

  http://www.itjobswatch.co.uk/ Thats the only one good site i have found, but missing for Belgium and for other European countries. I was searching a site which can tell the income source details for European developer (specially for Belgium). But mostly not a single website exist who tells the true. My situation: As a programmer myself in one company i use all my knowledge, 20++ hours a day (office , home, office, home) because every-time its challenge/complex/stress/over-time feature-requests, at the end of the year in Europe i was getting in total not even the lowest amount shown here (UK pound vs Euro + high-tech most of the time they use + speed in development): http://www.itjobswatch.co.uk/ In one company i have to use my best performance knowledge for whole year with: C, Java, PHP (Zend Framework, Cakephp), BASH, MySQL/DB2, Linux/Unix, Javascript, Dojo, JQuery, Css, Html, Xml. Company wants to pay lesser but always it has to be perfect and it has to be solid gold and diamond like quality. And the total amount in Europe is not sufficient for me if i compare with other countries and living cost in Europe including taxes. Is there any developers/community site where we can see by country, zone what is minimum to maximum income source getting offered to the developers? So that some developers who is in troubles, they can shout and speak up louder with those references?

• TechEd 2010 Day Two – No SQL Server in Sight

  - by BuckWoody

  Today I worked the booth at TechEd 2010, manning the new “Surface” computer, which is just the coolest object on the planet. After that I didn’t attend a single SQL Server session – instead I’ve been frequenting SharePoint, Microsoft Office, and even the High-Performance Computing sessions. The reason is that I get really high quality SQL Server presentations at PASS, SQL Saturdays, and online from Microsoft and other vendors. While there are SQL Server sessions here (after all, I’m giving one of them!) I tend to try and see things that I don’t normally get to learn about. And the cross-pollination between those technologies and mine is fantastic.     I’ve even managed to go to an Entity Framework presentation for the developers. I actually have (a little) more respect for that technology – and I’ve modified my presentation to encompass more of that information. So whenever you have the chance, take a walk outside your comfort zone. Even at PASS and SQL Saturdays (and certainly online) you can investigate technologies other than the ones you know best.  Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Raspberry Pi and Java SE: A Platform for the Masses

  - by Jim Connors

  One of the more exciting developments in the embedded systems world has been the announcement and availability of the Raspberry Pi, a very capable computer that is no bigger than a credit card.  At $35 US, initial demand for the device was so significant, that very long back orders quickly ensued. After months of patiently waiting, mine finally arrived.  Those initial growing pains appear to have been fixed, so availability now should be much more reasonable. At a very high level, here are some of the important specs: Broadcom BCM2835 System on a chip (SoC) ARM1176JZFS, with floating point, running at 700MHz Videocore 4 GPU capable of BluRay quality playback 256Mb RAM 2 USB ports and Ethernet Boots from SD card Linux distributions (e.g. Debian) available So what's taking place taking place with respect to the Java platform and Raspberry Pi? A Java SE Embedded binary suitable for the Raspberry Pi is available for download (Arm v6/7) here.  Note, this is based on the armel architecture, a variety of Arm designed to support floating point through a compatibility library that operates on more platforms, but can hamper performance.  In order to use this Java SE binary, select the available Debian distribution for your Raspberry Pi. The more recent Raspbian distribution is based on the armhf (hard float) architecture, which provides for more efficient hardware-based floating point operations.  However armhf is not binary compatible with armel.  As of the writing of this blog, Java SE Embedded binaries are not yet publicly available for the armhf-based Raspbian distro, but as mentioned in Henrik Stahl's blog, an armhf release is in the works. As demonstrated at the just-completed JavaOne 2012 San Francisco event, the graphics processing unit inside the Raspberry Pi is very capable indeed, and makes for an excellent candidate for JavaFX.  As such, plans also call for a Pi-optimized version of JavaFX in a future release too. A thriving community around the Raspberry Pi has developed at light speed, and as evidenced by the packed attendance at Pi-specific sessions at Java One 2012, the interest in Java for this platform is following suit. So stay tuned for more developments...

• Hardware wireless switch has no effect after suspend and 13.10 upgrade

  - by blaineh

  This seems to be a fairly chronic problem, as shown by the following questions: How do I fix a "Wireless is disabled by hardware switch" error? Wireless disabled by hardware switch "Wireless disabled by hardware switch" after suspend and other hardware buttons ineffective - how can I solve this? but no good solutions have been found! Wireless works fine after a reboot, but after a suspend the hardware switch (for my laptop this is f12) has no effect on the wireless, it is just permanently off, and shows that it is with a red LED. All My rfkill list all reads: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Any combination with rfkill <un>block wifi doesn't work, although one time first blocking then unblocking actually turned it on again. sudo lshw -C network reads: *-network DISABLED description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 01 serial: 78:e4:00:65:2e:3f width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.11.0-12-generic firmware=N/A ip=155.99.215.79 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:90100000-9010ffff *-network DISABLED description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 02 serial: c8:0a:a9:89:b4:30 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:42 ioport:2000(size=256) memory:90010000-90010fff memory:90000000-9000ffff memory:90020000-9002ffff Also, adding a /etc/pm/sleep.d/brcm.sh file as recommended here simply prevents the laptop from suspending at all, which of course is no good. This question has an answer urging to install the original driver, but it wasn't an "accepted answer" so I'd rather not take a chance on it. Also I'll admit I'm a bit lost on that and would like help doing so with the specific information I've given. xev shows that no internal event is triggered for my wireless switch (f12), but other function keys also acting as hardware switches work fine. I would be happy to provide more information, so long as you're willing to help me find it for you! This is a very annoying bug. I have a Compaq Presario CQ62. Edit. I just tried to reload bios defaults (or something) as shown by this video. Didn't work. Edit. I tried the contents of this answer, and it didn't work. Edit. I made a pastebin of dmesg. I couldn't even begin to understand the contents. Edit. Output of lspci | grep Network: 02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

• In agile environment, how is bug tracking and iteration tracking consolidated.

  - by DXM

  This topic stemmed from my other question about management-imposed waterfall-like schedule. From the responses in the other thread, I gathered this much about what is generally advised: Each story should be completed with no bugs. Story is not closed until all bugs have been addressed. No news there and I think we can all agree with this. If at a later date QA (or worse yet a customer) finds a bug, the report goes into a bug tracking database and also becomes a story which should be prioritized just like all other work. Does this sum up general handling of bugs in agile environment? If yes, the part I'm curious about is how do teams handle tracking in two different systems? (unless most teams don't have different systems). I've read a lot of advice (including Joel's blog) on software development in general and specifically on importance of a good bug tracking tool. At the same time when you read books on agile methodology, none of them seem to cover this topic because in "pure" agile, you finish iteration with no bugs. Feels like there's a hole there somewhere. So how do real teams operate? To track iterations you'd use (whiteboard, Rally...), to track bugs you'd use something from another set of products (if you are lucky enough, you might even get stuck with HP Quality Center). Should there be 2 separate systems? If they are separate, do teams spend time creating import/sync functionality between them? What have you done in your company? Is bug tracking software even used? Or do you just go straight to creating a story?

• Low pagerank backlinks - does Google penalize?

  - by Programmer Joe

  I have a new stock discussion forum and I would like to promote it. Specifically, I have two ideas in mind to help promote it: 1) Become a member at other stock discussion forums. Make high quality posts, build a good reputation, and leave a link to my own forum in a non intrusive way (ie. in signature or at the end of my posts). This approach makes sense because you can find other members in other forums that are interested in stock discussion and a backlink to your forum, as long as it is not done in an intrusive/spammy way, should come across as acceptable. 2) Promote my site by writing articles at Squidoo, Hubpages, etc. This approach also makes sense because that's what Squidoo and Hubpages is for. The problem with both these approaches is that when I leave a backlink to my site, the page that I am leaving a backlink from may have a low PR - most likely, a PR of 0. Now, I have read that after the Penguin update by Google, your site can be penalized if you have too many backlinks from low PR pages: http://www.entrepreneur.com/article/224339 So, I am caught in a dilemma: a) If I start promoting my site via other stock forums, Squidoo, Hubpages, etc, but the backlink to my site comes from a page with low PR, Google may penalize my site. b) However, if I don't promote my site, nobody will ever discover it (aside from other promotion techniques like social media promotion, directories, etc).

• POP Forums will be at Mix!

  - by Jeff

  If you've never been to Mix, you're missing out on what is arguably one of the best conferences that Microsoft does. I'm not just saying that because I work here... I felt that way before, having been to most of them. The breadth of people and disciplines make it a really exciting event that pushes it well beyond the "Redmond bubble," as I like to call it. You should go.In any case, there's an Open Source Fest happening the night before Mix starts, on Monday, from 6 to 9 p.m. There will be people there representing a ton of great projects, some as enormous as Umbraco, as well as people doing SDK's, controls and other neat stuff. Best of all, you get to vote for your favorites. Unless your favorite is Orchard, because Microsoft is sponsoring that directly. Or if it's POP Forums, not because Microsoft is sponsoring it, but because that's where I work in my day job. No prizes for me! Come by and say hello. I think the app will be nearly final by then, and it's already running on MouseZoom, one of my little side projects.The quality and diversity of open source projects around the Microsoft stack just keeps getting better. Our platform is also pretty great at running stuff we don't make. This will be a pretty exciting Mix. Can't wait!

  I have been running a ubuntu 10.04 with a patched version of lirc_zilog for two years. I upgraded to 12.04 and lirc_zilog is no longer working with my HD-PVR.

• disks not ready in array causes mdadm to force initramfs shell

  - by RaidPinata

  Okay, this is starting to get pretty frustrating. I've read most of the other answers on this site that have anything to do with this issue but I'm still not getting anywhere. I have a RAID 6 array with 10 devices and 1 spare. The OS is on a completely separate device. At boot only three of the 10 devices in the raid are available, the others become available later in the boot process. Currently, unless I go through initramfs I can't get the system to boot - it just hangs with a blank screen. When I do boot through recovery (initramfs), I get a message asking if I want to assemble the degraded array.

• Small, fast shopping cart setup

  - by R..

  I'm looking for an open source shopping cart solution that's simple and easy to setup. The requirements are: Quick setup for someone familiar with *nix webservers. Checkout via PayPal (other payment methods not needed). Customers should not have to create an account to make a purchase. At least a minimal level of inventory control. Ability to print/export a list of orders in compact form. Any recommendations for something I should try? Ability to get it up and working quickly is really my priority right now; if it's not ideal, it can be replaced (or, as I'm looking for open source, I can adapt it to fit the requirements better) at a later time. Edit: Really what I'm looking for is simplicity. This will be for a small local business, and the orders will consist of 1-10 items that are being delivered by a driver who needs a simple list of what each customer received when making delivery. Looking like a giant online computer/electronics/etc. store is definitely not a desirable quality. The simpler the interface presented to customers (who are used to purchasing through dumb web forms and paying COD), the better.

• The Healthy Tension That Mobility Creates

  - by Kathryn Perry

  A guest post by Hernan Capdevila, Vice President, Oracle Fusion Apps In my previous post, I talked about the value of the mobile revolution on businesses and workers. Now let me put on a different hat and view the world from the IT department and the IT leader’s viewpoint. The IT leader has different concerns – around privacy, potential liability of information leakage, and intellectual property protection. These concerns and the leader’s goals create a healthy tension with the users. For example, effective device management becomes a must have for the IT leader, especially if you look at the Android ecosystem as an example. There are benefits to the Android strategy, but there are also drawbacks, such as uniformity – in device management, in operating systems, and in the application taxonomy and capabilities. Whereas, if you compare Android to iOS, Apple's operating system, iOS is more unified, more streamlined, and easier to manage. In either case, this is where mobile device management in the cloud makes good sense. I don't think IT departments should be hosting device management and managing that complexity. It should be a cloud service and I predict it's going to be key for our customers. A New Focus for IT Departments So where does that leave the IT departments? I think their futures are in governance, which is a more strategic play than a tactical one. Device management is tactical and it's the “now” topic. But the mobile phenomenon, if you will, is going to drive significant change in terms of how IT plans, hosts, and deploys enterprise applications. For example, opening up enterprise applications for mobile users presents some challenges unless you deploy more complicated network topologies, such as virtual private networks and threat protection technology. If you really want employees to be mobile you need to remove those kinds of barriers. But I don’t think IT departments want to wrestle with exposing their private enterprise data centers and being responsible for hosted business applications – applications in a sense that they’re making vulnerable to the public world. This opens up a significant need and a significant driver for cloud applications. However, it's not just about taking away the complexity – it's also about taking away the responsibility. Why should every business have to carry the responsibility and figure out all the nuts and bolts of how to protect themselves in this public, mobile world? When you use apps in the cloud, either your vendor or your hosting partner should have figured all that out. They need to assure the business that they are adhering to all sorts of security and compliance regulations so users can be connected and have access to information anywhere anytime. More Ideas and Better Service What’s more interesting is the world of possibilities that the connected, cloud-based world enables. I believe that the one-size-fits-all, uber-best practices, lowest-common denominator-like capabilities will go away. IT will now be able to solve very specific business challenges for the different corporate functions it serves. In this new world, IT will play a key role in enabling different organizations within a company to be best in class and delivering greater value to the line of business managers. IT will actually help to differentiate. Net result is a more agile workforce and business because each department is getting work done its own way.

• Upgrade issues due to broken "dependency problems prevent configuration of linux-image-generic" error

  - by tsukune1791

  okay, I've recently upgrade from 11.10 to 12.04 and I've been having some issues. I don't know if its a bug or not, but I thought I would submit it here. Okay here's a little background; I ran the distro update from the update manager and got a couple errors that I didn't catch. the computer restarted, and when I logged the Launcher and my top bar of the Ubuntu desktop didn't load. While it was trying to load a couple error messages came up, I think they were called "apport", saying they couldn't send the bug information for some reason. I believe it said somethings wrong with my internet connection, but nothing's wrong with it. Anyway I tried running some things in terminal, namely sudo apt-get -f install sudo apt-get upgrade sudo apt-get dist-upgrade and keep getting the following errors; dustin@marceau-laptop:~$ sudo apt-get dist-upgrade [sudo] password for dustin: Reading package lists...

• Protecting Consolidated Data on Engineered Systems

  - by Steve Enevold

  In this time of reduced budgets and cost cutting measures in Federal, State and Local governments, the requirement to provide services continues to grow. Many agencies are looking at consolidating their infrastructure to reduce cost and meet budget goals. Oracle's engineered systems are ideal platforms for accomplishing these goals. These systems provide unparalleled performance that is ideal for running applications and databases that traditionally run on separate dedicated environments. However, putting multiple critical applications and databases in a single architecture makes security more critical. You are putting a concentrated set of sensitive data on a single system, making it a more tempting target.  The environments were previously separated by iron so now you need to provide assurance that one group, department, or application's information is not visible to other personnel or applications resident in the Exadata system. Administration of the environments requires formal separation of duties so an administrator of one application environment cannot view or negatively impact others. Also, these systems need to be in protected environments just like other critical production servers. They should be in a data center protected by physical controls, network firewalls, intrusion detection and prevention, etc Exadata also provides unique security benefits, including a reducing attack surface by minimizing packages and services to only those required. In addition to reducing the possible system areas someone may attempt to infiltrate, Exadata has the following features: 1.    Infiniband, which functions as a secure private backplane 2.    IPTables  to perform stateful packet inspection for all nodes               Cellwall implements firewall services on each cell using IPTables 3.    Hardware accelerated encryption for data at rest on storage cells Oracle is uniquely positioned to provide the security necessary for implementing Exadata because security has been a core focus since the company's beginning. In addition to the security capabilities inherent in Exadata, Oracle security products are all certified to run in an Exadata environment. Database Vault Oracle Database Vault helps organizations increase the security of existing applications and address regulatory mandates that call for separation-of-duties, least privilege and other preventive controls to ensure data integrity and data privacy. Oracle Database Vault proactively protects application data stored in the Oracle database from being accessed by privileged database users. A unique feature of Database Vault is the ability to segregate administrative tasks including when a command can be executed, or that the DBA can manage the health of the database and objects, but may not see the data Advanced Security  helps organizations comply with privacy and regulatory mandates by transparently encrypting all application data or specific sensitive columns, such as credit cards, social security numbers, or personally identifiable information (PII). By encrypting data at rest and whenever it leaves the database over the network or via backups, Oracle Advanced Security provides the most cost-effective solution for comprehensive data protection. Label Security  is a powerful and easy-to-use tool for classifying data and mediating access to data based on its classification. Designed to meet public-sector requirements for multi-level security and mandatory access control, Oracle Label Security provides a flexible framework that both government and commercial entities worldwide can use to manage access to data on a "need to know" basis in order to protect data privacy and achieve regulatory compliance  Data Masking reduces the threat of someone in the development org taking data that has been copied from production to the development environment for testing, upgrades, etc by irreversibly replacing the original sensitive data with fictitious data so that production data can be shared safely with IT developers or offshore business partners  Audit Vault and Database Firewall Oracle Audit Vault and Database Firewall serves as a critical detective and preventive control across multiple operating systems and database platforms to protect against the abuse of legitimate access to databases responsible for almost all data breaches and cyber attacks.  Consolidation, cost-savings, and performance can now be achieved without sacrificing security. The combination of built in protection and Oracle’s industry-leading data protection solutions make Exadata an ideal platform for Federal, State, and local governments and agencies.

• A new mission statement for my school's algorithms class

  - by Eric Fode

  The teacher at Eastern Washington University that is now teaching the algorithms course is new to eastern and as a result the course has changed drastically mostly in the right direction. That being said I feel that the class could use a more specific, and industry oriented (since that is where most students will go, though suggestions for an academia oriented class are also welcome) direction, having only worked in industry for 2 years I would like the community's (a wider and much more collectively experienced and in the end plausibly more credible) opinion on the quality of this as a statement for the purpose an algorithms class, and if I am completely off target your suggestion for the purpose of a required Jr. level Algorithms class that is standalone (so no other classes focusing specifically on algorithms are required). The statement is as follows: The purpose of the algorithms class is to do three things: Primarily, to teach how to learn, do basic analysis, and implement a given algorithm found outside of the class. Secondly, to teach the student how to model a problem in their mind so that they can find a an existing algorithm or have a direction to start the development of a new algorithm. Third, to overview a variety of algorithms that exist and to deeply understand and analyze one algorithm in each of the basic algorithmic design strategies: Divide and Conquer, Reduce and Conquer, Transform and Conquer, Greedy, Brute Force, Iterative Improvement and Dynamic Programming. The Question in short is: do you agree with this statement of the purpose of an algorithms course, so that it would be useful in the real world, if not what would you suggest?

• Complimentary Refills

  - by onefloridacoder

  My son and I were out to dinner and right after we sat down, he combs the menu to locate the soda  selection.  Then he looks up at me and says “Looks like we get free refills here, sweet!”  While we were sitting there I was thinking where that statement came from and I remember one time where he was helping to figure out the tip and saw that were we charged for six sodas, but there were only four of us at the table.  I would say that’s when this started for eateries he’s not familiar with. I was talking a friend of mine this week and this thought came to me, why can’t we manage expectations like my son – find out before the order is placed.  Find out what’s expected first then use the other bits of guidance to move forward.  But how many times have we all paid way to much for something we thought was free on a project – me, plenty.  This quote is going up in my work space, next to one I picked up Corey Haines’ Software Craftsmanship talk at Open Agile Romania - “Work != Practice”.  So if anyone else has gotten burnt, maybe check the menu, it will be in the area where the customer will pick two from the list of “Price, Quality, or Speed”.  Refills will be listed just beneath that.

• Impossible to select folders and files with mouse (Ubuntu 12.04)

  - by François

  First-time post for me here (after being a regular reader for two years though) so thank you all for the quality of replies and help provided. My problem is very simple apparently but a tricky one. I just installed the Ubuntu 12.04(1) along with the Gnome3-shell environment on my new pc desktop Acer Aspire X3995 (see config below). Everything work (more or less) so far (I still have problems of sound and disabled 2-fingers gestures with my screen -- which I will have to deal with xconfig settings I think -- though), but the main problem is that I cannot select files/folders with my USB mouse. When I try to double click on them, nothing happen (sometimes one folder or file is selected but then unselected again). Note that the navigation works perfectly from the USB keyboard and from the touch-screen (I am using a 23" wide touch-screen Acer Monitor T231Hbmid). Also, the mouse works perfectly with other menu navigation, with the only difference that the text of certain menus is selected as if I was holding the left click on them. So I assume the problem is only related to the mouse. Needless to say that the usual basic hardware checks have been performed (unplugging, powered-off, etc.). My level is simply "advanced user", meaning that if you provide me with intelligible input I should find my way, but please don't expect too much technical/specific knowledge... :) Please let me know if you need more information on this bug. Now, fingers crossed... and thanks in advance! Ciao, François Config of Acer Aspire X3995: Ubuntu 12.04 / Gnome3-shell environment / Intel Core i5 3450 / nVidia GeForce 605, 1Gb.

• On The Road with the HR Community

  - by Kathryn Perry

  A guest post by Steve Boese, Director, Talent Strategy, Oracle One of the best ways to connect with and to get a feel for what is on the minds of Human Resources leaders is to get out of the office and hit the road. I’ve had the great honor to attend and/or present at a number of events recently, including the massive SHRM Annual Conference, the HR Florida Conference, and Taleo World in Chicago. These events, and many others, offer solution providers, talent management professionals, business leaders, and even more casual observers of the Human Resources field with tremendous opportunities to connect, to share information, and to learn from each other. Attending the conferences also give people a sense of how they can improve and enhance their skills and knowledge, learn about the latest workforce technologies, and bring new and innovative ideas back to their organizations. And sure, the parties and conference swag can be pretty nice as well! If you attend a few of these industry events, one of the most beneficial by-products that you can emerge with -- whether you are on the front lines in HR at your organization, or as we are at Oracle, in the business of developing and delivering innovative and impactful technology solutions to our customers -- is to get a larger sense of the big ideas and major trends, concerns, and challenges facing organizations all across the landscape, and to be able to better understand how your strategies and solutions can be improved with this greater perspective. So what are HR folks discussing and debating? What questions and problems keep them up at night? What are the bloggers and large community of HR social media enthusiasts buzzing about? From my perspective some of the common themes you see over and again across the HR community break down (broadly), into three main areas: Talent attraction - How can we locate, attract, recruit, and hire the best talent possible? What new strategies, approaches, and technologies can help us in this critically important area? What role do external social networks like LinkedIn, Facebook, and Twitter play in the increasingly competitive search for talent? Talent Retention - How can we make sure to keep that talent on our team? What engagement, development, recognition, and compensation tools can help us in this regard? How can we continue, (or become), an employer of choice? What is our unique and compelling employer value proposition? Talent Empowerment - How can we put our employees in the best position to succeed? What can we do to better align our talent with the organization’s mission and goals, while simultaneously providing the best and most driven to succeed individuals a clear path to achieve their career goals and aspirations? How can new technologies, particularly social and collaboration tools help in this area? While these are the ‘big themes’ that I know I have seen this year, certainly they are not really new, nor are they likely to fundamentally change in the next year or two. I think the reason is that at the core of any successful enterprise is a collection of smart, interested, engaged, challenged, and empowered group of people. And that was likely the case 10 or 20 years ago, and will probably be the case 10 or 20 years into the future. But what has changed, and what you can see -- evidenced by simply following the Twitter backchannel for an event and by reading some of the many fantastic HR blogs out there -- is that the HR professional's ability, along with technology solution providers like Oracle, to connect, to more openly share information with each other, and to make each other better in the process, (and to create new, improved, and more innovative solutions), has never been greater. And I think it is with this heretofore unprecedented level of opportunity to connect with other members of the community that HR professionals will be better equipped to help their organizations attract, retain, and empower their teams. We at Oracle HCM look forward to continuing to meet, engage, and connect with the HR community in the coming months. Until then -- follow us on Twitter and Facebook.

• Future Of F# At Jazoon 2011

  - by Alois Kraus

  I was at the Jazoon 2011 in Zurich (Switzerland). It was a really cool event and it had many top notch speaker not only from the Microsoft universe. One of the most interesting talks was from Don Syme with the title: F# Today/F# Tomorrow. He did show how to use F# scripting to browse through open databases/, OData Web Services, Sharepoint, …interactively. It looked really easy with the help of F# Type Providers which is the next big language feature in a future F# version. The object returned by a Type Provider is used to access the data like in usual strongly typed object model. No guessing how the property of an object is called. Intellisense will show it just as you expect. There exists a range of Type Providers for various data sources where the schema of the stored data can somehow be dynamically extracted. Lets use e.g. a free database it would be then let data = DbProvider(http://.....); data the object which contains all data from e.g. a chemical database. It has an elements collection which contains an element which has the properties: Name, AtomicMass, Picture, …. You can browse the object returned by the Type Provider with full Intellisense because the returned object is strongly typed which makes this happen. The same can be achieved of course with code generators that use an input the schema of the input data (OData Web Service, database, Sharepoint, JSON serialized data, …) and spit out the necessary strongly typed objects as an assembly. This does work but has the downside that if the schema of your data source is huge you will quickly run against a wall with traditional code generators since the generated “deserialization” assembly could easily become several hundred MB. *** The following part contains guessing how this exactly work by asking Don two questions **** Q: Can I use Type Providers within C#? D: No. Q: F# is after all a library. I can reference the F# assemblies and use the contained Type Providers? D: F# does annotate the generated types in a special way at runtime which is not a static type that C# could use. The F# type providers seem to use a hybrid approach. At compilation time the Type Provider is instantiated with the url of your input data. The obtained schema information is used by the compiler to generate static types as usual but only for a small subset (the top level classes up to certain nesting level would make sense to me). To make this work you need to access the actual data source at compile time which could be a problem if you want to keep the actual url in a config file. Ok so this explains why it does work at all. But in the demo we did see full intellisense support down to the deepest object level. It looks like if you navigate deeper into the object hierarchy the type provider is instantiated in the background and attach to a true static type the properties determined at run time while you were typing. So this type is not really static at all. It is static if you define as a static type that its properties shows up in intellisense. But since this type information is determined while you are typing and it is not used to generate a true static type and you cannot use these “intellistatic” types from C#. Nonetheless this is a very cool language feature. With the plotting libraries you can generate expressive charts from any datasource within seconds to get quickly an overview of any structured data storage. My favorite programming language C# will not get such features in the near future there is hope. If you restrict yourself to OData sources you can use LINQPad to query any OData enabled data source with LINQ with ease. There you can query Stackoverflow with The output is also nicely rendered which makes it a very good tool to explore OData sources today.
