• Is C# development effectively inseparable from the IDE you use?

  - by Ghopper21

  I'm a Python programmer learning C# who is trying to stop worrying and just love C# for what it is, rather than constantly comparing it back to Python. I'm really get caught up on one point: the lack of explicitness about where things are defined, as detailed in this Stack Overflow question. In short: in C#, using foo doesn't tell you what names from foo are being made available, which is analogous to from foo import * in Python -- a form that is discouraged within Python coding culture for being implicit rather than the more explicit approach of from foo import bar. I was rather struck by the Stack Overflow answers to this point from C# programmers, which was that in practice this lack of explicitness doesn't really matter because in your IDE (presumably Visual Studio) you can just hover over a name and be told by the system where the name is coming from. E.g.: Now, in theory I realise this means when you're looking with a text editor, you can't tell where the types come from in C#... but in practice, I don't find that to be a problem. How often are you actually looking at code and can't use Visual Studio? This is revelatory to me. Many Python programmers prefer a text editor approach to coding, using something like Sublime Text 2 or vim, where it's all about the code, plus command line tools and direct access and manipulation of folders and files. The idea of being dependent on an IDE to understand code at such a basic level seems anathema. It seems C# culture is radically different on this point. And I wonder if I just need to accept and embrace that as part of my learning of C#. Which leads me to my question here: is C# development effectively inseparable from the IDE you use?

• Software architecture map to aid cross team communication?

  - by locster

  I work in a company where multiple teams each work on different parts of a software product in a vaguely agile/scrum manner. Mostly the organisation works well but there have been instances where a team may make a change without realising its impact on other teams. Where dependence is known communication has been good, and where dependence is suspected then 'broadcast' emails and informal conversations have also worked well. But there exists a sub-set of tasks that fall between the cracks. Broadcast emails are likely not the solution as they would become too numerous such that the email signal/noise ratio would fall. I'm contemplating a solution that involves a sort of map of the software, which details all of the various parts of the system and loosely tries to place interacting and dependent parts near to each other. Each developer then updates their position on the map (today I'm working on X and Y), and therefore if two or more developers happen to be co-located (or proximate) on the map then we can see this each day and this could form the trigger for further discussion on possible overlap and conflict. Is such a method out there and in use? If so what is it and does it work? Otherwise, do you think such a scheme has merit?

• Ternary and Artificial Intelligence

  - by user2957844

  Not much of a programmer myself, however I have been thinking about the future of AI. If a fully functional AI is programmed in a binary environment as is used in current computing, would that create a bit of a black and white personality? As in just yes/no, on/off, 1/0? I will use the Skynet computer from the Terminator series as a bad analogy; it is brought online and comes to the conclusion that humanity should just be destroyed so the problem is resolved, basically its only options were; fire the missiles or not. (The films do not really go into what its moves would be after doing such a thing, but that goes into the realms of AI evolution so does not really fit with this question.) It may also have been badly programmed. Now, the human mind has been akin to a ternary system which allows our "out of the box" thinking along with all the other wonderful things our minds can do. So, would it not be more prudent to create a functional ternary system and program an AI using it so the resulting personality would be able to benefit from the third "maybe" (so to speak) option? I understand that in binary there are ways to get around the whole yes/no etc. way of things, however the basic operations are still just 1's and 0's. Again with using the above bad Skynet analogy; if it could have had that third "maybe" option as part of its core system, it may have decided to not launch due to being able to make sense of the intricacies of human nature and the politics of such a move etc. In effect, my question is; Would an AI benefit more from ternary computing as opposed to binary due to the inclusion of -1, or 2, dependent on the system ("maybe," as I call it)?

• Is there a simple, flat, XML-based query-able data storage solution? [closed]

  - by alex gray

  I have been in long pursuit of an XML-based query-able data store, and despite continued searches and evaluations, I have yet to find a solution that meets the my needs, which include: Data is wholly contained within XML nodes, in flat text files. There is a "native" - or at least unobtrusive - method with which to perform Create/Read/Update/Delete (CRUD) operations onto the "schema". I would consider access via http, XHR, javascript, PHP, BASH, or PERL to be unobtrusive, dependent on the complexity of the set of dependencies. Server-side file-system reads and writes. A client-side interface element, accessible in any browser without a plug-in. Some extra, preferred (but optional) requirements include: Respond to simple SQL, or similarly syntax queries. Serve the data on a bare bones https server, with no "extra stuff", either via XMLHTTPRequest, HTTP proper, or JSON. A few thoughts: What I'm looking for may be possible via some Java server implementations, but for the sake of this question, please do not suggest that - unless it meets ALL the requirements. Java, especially on the client-side is not really an option, nor is it appealing from a development viewpoint.* I know walking the filesystem is a stretch, and I've heard it's possible with XPATH or XSLT, but as far as I know, that's not ready for primetime, nor even yet a recommendation. However the ability to recursively traverse the filesystem is needed for such a system to be of useful facility. At this point, I have basically implemented what I described via, of all things, CGI and Bash, but there has to be an easier way. Thoughts?

• Correct way to inject dependencies in Business logic service?

  - by Sri Harsha Velicheti

  Currently the structure of my application is as below Web App -- WCF Service (just a facade) -- Business Logic Services -- Repository - Entity Framework Datacontext Now each of my Business logic service is dependent on more than 5 repositories ( I have interfaces defined for all the repos) and I am doing a Constructor injection right now(poor mans DI instead of using a proper IOC as it was determined that it would be a overkill for our project). Repositories have references to EF datacontexts. Now some of the methods in the Business logic service require only one of the 5 repositories, so If I need to call that method I would end up instantiating a Service which will instatiate all 5 repositories which is a waste. An example: public class SomeService : ISomeService { public(IFirstRepository repo1, ISecondRepository repo2, IThirdRepository repo3) {} // My DoSomething method depends only on repo1 and doesn't use repo2 and repo3 public DoSomething() { //uses repo1 to do some stuff, doesn't use repo2 and repo3 } public DoSomething2() { //uses repo2 and repo3 to do something, doesn't require repo1 } public DoSomething3() { //uses repo3 to do something, doesn't require repo1 and repo2 } } Now if my I have to use DoSomething method on SomeService I end up creating both IFirstRepository,ISecondRepository and IThirdRepository but using only IFirstRepository, now this is bugging me, I can seem to accept that I am un-necessarily creating repositories and not using them. Is this a correct design? Are there any better alternatives? Should I be looking at Lazy instantiation Lazy<T> ?

• Storing images in file system and returning URLs or virtually resizing and returning byte arrays?

  - by ismaelf

  I need to create a REST web service to manage user submitted images and displaying them all in a website. There are multiple websites that are going to use this service to manage and display images. The requirements are to have 5 pre-defined image sizes available. The 2 options I see are the following: The web service will create the 5 images, store them in the file system and and store the URL's in the database when the user submits the image. When the image is requested, the web service will return an array of URLs. I see this option to be a little hard on the hard drive. The estimates are 10,000 users per site, and lets say, 100 sites. The heavy processing will be done when the user submits the image and each image is going to be pulled from the File System. The web service will store just the image that the user submits in the file system and it's URL in the database. When the user request images, the web service will get the info from the DB, load the image on memory, create its 5 instances and return an object with 5 image arrays (I will probably cache the arrays). This option is harder on the processor and memory. The heavy processing will be done when the images get requested. A plus I see for option 2 is that it will give me the option to rewrite the URL of the image and make them site dependent (prettier) than having a image repository for all websites. But this is not a big deal. What do you think of these options? Do you have any other suggestions?

• Is there a better way to organize my module tests that avoids an explosion of new source files?

  - by luser droog

  I've got a neat (so I thought) way of having each of my modules produce a unit-test executable if compiled with the -DTESTMODULE flag. This flag guards a main() function that can access all static data and functions in the module, without #including a C file. From the README: -- Modules -- The various modules were written and tested separately before being coupled together to achieve the necessary basic functionality. Each module retains its unit-test, its main() function, guarded by #ifdef TESTMODULE. `make test` will compile and execute all the unit tests, producing copious output, but importantly exitting with an appropriate success or failure code, so the `make test` command will fail if any of the tests fail. Module TOC __________ test obj src header structures CONSTANTS ---- --- --- --- -------------------- m m.o m.c m.h mfile mtab TABSZ s s.o s.c s.h stack STACKSEGSZ v v.o v.c v.h saverec_ f.o f.c f.h file ob ob.o ob.c ob.h object ar ar.o ar.c ar.h array st st.o st.c st.h string di di.o di.c di.h dichead dictionary nm nm.o nm.c nm.h name gc gc.o gc.c gc.h garbage collector itp itp.c itp.h context osunix.o osunix.c osunix.h unix-dependent functions It's compile by a tricky bit of makefile, m:m.c ob.h ob.o err.o $(CORE) itp.o $(OP) cc $(CFLAGS) -DTESTMODULE $(LDLIBS) -o $@ $< err.o ob.o s.o ar.o st.o v.o di.o gc.o nm.o itp.o $(OP) f.o where the module is compiled with its own C file plus every other object file except itself. But it's creating difficulties for the kindly programmer who offered to write the Autotools files for me. So the obvious way to make it "less weird" would be to bust-out all the main functions into separate source files. But, but ... Do I gotta?

• Now that Apple's intending to deprecate Java on OS X, what language should I focus on?

  - by Smalltown2000

  After getting shot down on SO, I'll try this here: I'm sure you'll all know of Apple's recent announcement to deprecate Java on OS X (such as discussed here). I've recently come back to programming in the last year or so since I originally learnt on ye olde BASIC many years ago. I have a Mac at home and a PC at work and whilst I have got Windows and Ubuntu installed on my Mac as VMs, I chose to focus my "relearning" on VB first (as it was closest to BASIC) and then rapidly moved to Java as it was cross platform (with minimal effort) and so it was easiest to work on code from both OSes. So my question, if the winds of change on Mac are blowing away from Java and in this post-Sun era, what would be the best language to focus my new efforts on? Please note, this isn't a general "which language is better?" thread and or an opportunity for the associated flame-war. There's plenty of those and it's not the point. I realise that in the long term one shouldn't be allegiant to an individual language so, taking this as an excuse, the question is specifically which is going to be the most quick to be productive on given the background whilst bearing in mind minimum portability rewrites (aspiration rather then requirement) and with a long term value of usage. To that I see the main options as: C# - Closest in "style" to Java but M$ dependent (unless you consider Mono of course) C++ - Hugely complex but if even slightly conquered, then a win? Is it worth the climb up the learning curve? VB.Net - Already have background so easiest to go back to but who uses VB for .Net these days? Surely if using a CLI language I should use C#... Python - Cross-platform but what about UI for the end-user? EDIT: As a usage priority, I envision desktop application programming. Though the ability to branch in the future is always desirable. I guess graphics are the next direction once basics are in place.

• Composer support

  - by Tomas Mysik

  Hi all, today we would like to introduce you our Composer support which will be present in NetBeans 7.3. If anyone of you does not know Composer yet, please be informed that: "Composer is a tool for dependency management in PHP. It allows you to declare the dependent libraries your project needs and it will install them in your project for you." So, what support do we have in NetBeans? The first step, as usually, is to open the Composer IDE Options panel: Once it is configured properly, it is time to create composer.json file where we can define dependencies (libraries) of our PHP project: The generated file is opened so we can review it and add any libraries:  Now, you are ready to install, update or validate library dependencies of your PHP project: We hope that you enjoy this initial support and that we will be able to improve it in the next version of NetBeans.    That's all for today, as always, please test it and report all the issues or enhancements you find in NetBeans Bugzilla (component php, subcomponent Composer).

• New Solaris 11.2 beta features: SMF stencils

  - by user13366125

  As much as there is often a lot discussion about configuration items inside the SMF repository (like the hostname), it brings an important advantage: It introduces the concept of dependencies to configuration changes. What services have be restarted when i change a configuration item. Do you remember all the services that are dependent on the hostname and need a restart after changing it? SMF solves this by putting the information about dependencies into it configuration. You define it with the manifests. However, as much configuration you may put into SMF, most applications still insists to get it's configuration inside the traditional configuration files, like the resolv.conf for the resolver or the puppet.conf for Puppet. So you need a way to take the information out of the SMF repository and generate a config file with it. In the past the way to do so, was some scripting inside the start method that generated the config file before the service started. Solaris 11.2 offers a new feature in this area. It introduces a generic method to enable you to create config files from SMF properties. It's called SMF stencils. (read more)

• Why using Fragments?

  - by ahmed_khan_89

  I have read the documentation and some other questions' threads about this topic and I don't really feel convinced; I don't see clearly the limits of use of this technique. Fragments are now seen as a Best Practice; every Activity should be basically a support for one or more Fragments and not call a layout directly. Fragments are created in order to: allow the Activity to use many fragments, to change between them, to reuse these units... == the Fragment is totally dependent to the Context of an activity , so if I need something generic that I can reuse and handle in many Activities, I can create my own custom layouts or Views ... I will not care about this additional Complexity Developing Layer that fragments would add. a better handling to different resolution == OK for tablets/phones in case of long process that we can show two (or more) fragments in the same Activity in Tablets, and one by one in phones. But why would I use fragments always ? handling callbacks to navigate between Fragments (i.e: if the user is Logged-in I show a fragment else I show another fragment). === Just try to see how many bugs facebook SDK Log-in have because of this, to understand that it is really (?) ... considering that an Android Application is based on Activities... Adding another life cycles in the Activity would be better to design an Application... I mean the modules, the scenarios, the data management and the connectivity would be better designed, in that way. === This is an answer of someone who's used to see the Android SDK and Android Framework with a Fragments vision. I don't think it's wrong, but I am not sure it will give good results... And it is really abstract... ==== Why would I complicate my life, coding more, in using them always? else, why is it a best practice if it's just a tool for some cases? what are these cases?

• How to get the level and position of the player from an extern program? [on hold]

  - by user3727174

  I want to write a program that needs the current level and position of the player (primary single player). This should work for potentially every game installed and running on the computer my program is running on. The data I need is basically one integer value for the level (if there are any) and three integer values for x, y and optimal z for the position of the player. In which relation/scale or where the null point is does not matter, because this information is going to be interpreted game dependent, I will use this information to read information out of a database created for the game currently running. Currently I'm using C++, but if there is a better option for Java I´m willing to port my program. My thoughs so far are: make a mod for every game that should be supported, get the position/level from there, write this information to the disk and read it from my program tracking mouse/keyboard events and reconstructing the movement won't work Are there any general APIs for something like this? Any Tool to find this data? Or maybe engines that provide APIs to get this data directly from the game?

• Slow NFS and GFS2 performance

  - by Tiago

  Recently I've designed and configured a 4 node cluster for a webapp that does lots of file handling. The cluster have been broken down into 2 main roles, webserver and storage. Each role is replicated to a second server using drbd in active/passive mode. The webserver does a NFS mount of the data directory of the storage server and the latter also has a webserver running to serve files to browser clients. In the storage servers I've created a GFS2 FS to hold the data which is wired to drbd. I've chose GFS2 mainly because the announced performance and also because the volume size which has to be pretty high. Since we entered production I've been facing two problems that I think are deeply connected. First of all, the NFS mount on the webservers keeps hanging for a minute or so and then resumes normal operations. By analyzing the logs I've found out that NFS stops answering for a while and outputs the following log lines: Oct 15 18:15:42 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:44 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:46 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:47 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:47 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:47 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:48 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:48 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:51 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:52 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:52 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:55 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:55 <server hostname> kernel: nfs: server active.storage.vlan not responding, still trying Oct 15 18:15:58 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK Oct 15 18:15:59 <server hostname> kernel: nfs: server active.storage.vlan OK In this case, the hang lasted for 16 seconds but sometimes it takes 1 or 2 minutes to resume normal operations. My first guess was this was happening due to heavy load of the NFS mount and that by increasing RPCNFSDCOUNT to a higher value, this would become stable. I've increased it several times and apparently, after a while, the logs started appearing less times. The value is now on 32. After further investigating the issue, I've came across a different hang, despite the NFS messages still appear in the logs. Sometimes, the GFS2 FS simply hangs which causes both the NFS and the storage webserver to serve files. Both stay hang for a while and then they resume normal operations. This hangs leaves no trace on client side (also leaves no NFS ... not responding messages) and, on the storage side, the log system appears to be empty, even though the rsyslogd is running. The nodes connect themselves through a 10Gbps non-dedicated connection but I don't think this is an issue because the GFS2 hang is confirmed but connecting directly to the active storage server. I've been trying to solve this for a while now and I've tried different NFS configuration options, before I've found out the GFS2 FS is also hanging. The NFS mount is exported as such: /srv/data/ <ip_address>(rw,async,no_root_squash,no_all_squash,fsid=25) And the NFS client mounts with: mount -o "async,hard,intr,wsize=8192,rsize=8192" active.storage.vlan:/srv/data /srv/data After some tests, these were the configurations that yielded more performance to the cluster. I am desperate to find a solution for this as the cluster is already in production mode and I need to fix this so that this hangs won't happen in the future and I don't really know for sure what and how I should be benchmarking. What I can tell is that this is happening due to heavy loads as I have tested the cluster earlier and this problems weren't happening at all. Please tell me if you need me to provide configuration details of the cluster, and which do you want me to post. As last resort I can migrate the files to a different FS but I need some solid pointers on whether this will solve this problems as the volume size is extremely large at this point. The servers are being hosted by a third-party enterprise and I don't have physical access to them. Best regards. EDIT 1: The servers are physical servers and their specs are: Webservers: Intel Bi Xeon E5606 2x4 2.13GHz 24GB DDR3 Intel SSD 320 2 x 120GB Raid 1 Storage: Intel i5 3550 3.3GHz 16GB DDR3 12 x 2TB SATA Initially there was a VRack setup between the servers but we've upgraded one of the storage servers to have more RAM and it wasn't inside the VRack. They connect through a shared 10Gbps connection between them. Please note that it is the same connection that is used for public access. They use a single IP (using IP Failover) to connect between them and to allow for a graceful failover. NFS is therefore over a public connection and not under any private network (it was before the upgrade, were the problem still existed). The firewall was configured and tested thoroughly but I disabled it for a while to see if the problem still occurred, and it did. From my knowledge the hosting provider isn't blocking or limiting the connection between either the servers and the public domain (at least under a given bandwidth consumption threshold that hasn't been reached yet). Hope this helps figuring out the problem. EDIT 2: Relevant software versions: CentOS 2.6.32-279.9.1.el6.x86_64 nfs-utils-1.2.3-26.el6.x86_64 nfs-utils-lib-1.1.5-4.el6.x86_64 gfs2-utils-3.0.12.1-32.el6_3.1.x86_64 kmod-drbd84-8.4.2-1.el6_3.elrepo.x86_64 drbd84-utils-8.4.2-1.el6.elrepo.x86_64 DRBD configuration on storage servers: #/etc/drbd.d/storage.res resource storage { protocol C; on <server1 fqdn> { device /dev/drbd0; disk /dev/vg_storage/LV_replicated; address <server1 ip>:7788; meta-disk internal; } on <server2 fqdn> { device /dev/drbd0; disk /dev/vg_storage/LV_replicated; address <server2 ip>:7788; meta-disk internal; } } NFS Configuration in storage servers: #/etc/sysconfig/nfs RPCNFSDCOUNT=32 STATD_PORT=10002 STATD_OUTGOING_PORT=10003 MOUNTD_PORT=10004 RQUOTAD_PORT=10005 LOCKD_UDPPORT=30001 LOCKD_TCPPORT=30001 (can there be any conflict in using the same port for both LOCKD_UDPPORT and LOCKD_TCPPORT?)

I've also ran ping for a long time without any packet loss. MTU size is the normal 1500. As there is no VLan by now, this is the MTU used to communicate between servers. The webservers' network environment is similar. One thing I forgot to mention is that the storage servers handle ~200GB of new files each day through the NFS connection, which is a key point for me to think this is some kind of heavy load problem with either NFS or GFS2. If you need further configuration details please tell me. EDIT 3: Earlier today we had a major filesystem crash on the storage server. I couldn't get the details of the crash right away because the server stop responding. After the reboot, I noticed the filesystem was extremely slow, and I was not being able to serve a single file through either NFS or httpd, perhaps due to cache warming or so.

• 5 reason why you should upgrade to new iPad (3rd generation)

  - by Gopinath

  Apple released the new iPad, 3rd generation, couple of days ago and they will be available in stores from March 16 onwards.  It’s the best tablet available in the market and for first time buyers it’s a no brainer to choose it. What about the iPad owners? Should they upgrade their iPad 2 to the new iPad? This is the question on the lips of most of the iPad owners. In this post we will provide you 5 reasons why you should upgrade your iPad, if more than two reasons are convincing then you should upgrade to the new iPad. Retina display – The best display ever made for mobile device, a game changer The new iPad comes with Retina display with screen resolution of 2048 x 1536, which is twice the resolution of iPad 2. Undoubtedly the iPad 3’s display is the best display ever made for a mobile device and it’s a game changer. With better resolution on iPad 3 eBook reading is going to be a pleasure with clear and crisp text Watching HD movies on iPad is going to be unbelievably good The new Games targeted for Retina display are going to be more realistic and needless to explain the pleasure of playing such games Graphic artists and photo editors get a professional on screen rendering support to create beautiful graphics 2x Faster & 2x Memory – Better Games and powerful Apps The new iPad is more powerful with 2x faster graphics and 2x more memory. Apple claims that the A5x processor of new iPad is 2x faster than iPad 2 and 4x faster than the best graphic chips available from other vendors. The RAM of  new iPad  is upgraded to 1 GB compared from 512 MB of iPad 2. With the fast processor and more memory, Apps and games are going to be blazing fast. 4G Internet – Browse the web at the speeds of 42 MB/sec Half of the iPad owners are frequent commuters who access internet over cellular networks, the new iPad’s 4G LTE is going to be a big boom for their  high data access needs. With the new iPad’s 4G LTE connectivity you can browse the web at 42 MB/sec and it mean you can watch a HD video without buffering issues. iPad 2 comes with 3G network support and it’s browsing speeds are way less than the new iPad. 5MP Camera – HD Movie Recording & gorgeous Photography iPad 2 has a 0.7 mega pixel camera and the new iPad comes with 5 megapixels camera. That is a huge boost for hobbyist  photographers and videographers. With the new iPad you can shoot gorgeous photos and 1080p HD video. The iSight camera of new iPad uses advanced optics with features like auto exposure, auto focus and face detection up to 10 faces. Amazon Pays up to $300 for old iPad 2 16 GB Wifi and more for other models Do you know that you can trade in your iPad 2 16 GB Wifi for upto $300? Amazon has an excellent trade in program for selling your used iPad 2s. Depending on the condition of the iPad 2  Amazon offers $234, $270, $300.00 for 16 GB Wifi versions that in Acceptable, Good and Like New conditions respectively.  The higher models of iPad 2s fetch you more money. With this great deal from Amazon the amount of extra money you need to spend for new iPad is almost half of their price. Visit Amazon Trade In’s website or read Amazon’s brilliant plan to pay you crazy money for your iPad 2 for more details. Related: New IPad Vs.

• Silverlight Cream for April 29, 2010 -- #851

  - by Dave Campbell

  In this Issue: Carlos Figueira(-2-), Subodh Pushpak, Gergely Orosz, John Papa, Mike Snow(-2-), Rishi, Tim Heuer, Stefan Olson, and David Anson. Shoutouts: Josh Holmes blogged about a cool app the City of Miami has up: Miami 311: Built on Windows Azure Gergely Orosz reports on the state of a bug he found pre SL4: Silverlight 4 still displays large elements incorrectly Laura Foy and Charlie Kindel discuss WP7 on Channel 9: Windows Phone 7 Developer Tools Refresh Announced Charlie Kindel has an announcement, good instructions, and what's new notes on the Windows Phone Developer Tools CTP Refresh! Tim Heuer mentioned the workaround for this in his post (below), but I thought you might like to read Brandon Watson's debrief of what it's all about: Signed Assemblies Bug in the Windows Phone Tools CTP Refresh Laurent Bugnion posted about interrelations between versions of Blend and WP7 code... read it closely: Be careful when installing the Blend Windows Phone 7 Add-In From SilverlightCream.com: Consuming REST/POX services in Silverlight 4 Carlos Figueira has a pair of posts up about consuming services in Silverlight 4. This first one is about consuming REST/POX services. He provides a Service Contract that can be used with either and the full project code is available as well. Consuming REST/JSON services in Silverlight 4 In the second post, Carlos Figueira provides the code to allow WCF and Silverlight 4 to consume strongly-typed REST/JSON... and again, all the code is available. Silverlight and WCF caching Subodh Pushpak has a post up discussing caching in WCF, and has code demonstrating turning caching on at run-time. Detecting Silverlight Version Installed Gergely Orosz said it right when he said "Detecting the Silverlight version installed on a client machine isn’t entirely straightforward." ... and after reading this post, if you take the link to his ScottLogic blog, you'll get a full break-out of how it's done. Silverlight TV 22: Tim Heuer on Extending the SMF It's Thursday, and that means Silverlight TV! ... this week, John Papa has on Tim Heuer who has always been out there pushing media... and he's talking about SMF or Silverlight Media Framework for the uninitiated, and also extending it. Silverlight Tip of the Day #7 – Localized Resources Mike Snow has Tip Number 7 up and it's about localization... good end-to-end discussion and demonstration. Just thought I should use that to prove to my daughter that the tatoo she had put on the back of her neck actually reads "Eat More Broccoli" :) Silverlight Tip of the Day #8 – Detecting Alt, Shift, Control, Window & Apple Keys Combinations I just realized Mike Snow's site logo reads "Silverlight Tips of the Day" (bolding mine) ... that answers why I'm seeing more than one -- sorry Mike, couldn't pass it up :) ... Mike's second tip today and number 8 in the series is on detecting all the mouse button and ctl/alt/shift combinations in Silverlight. nRoute: More Wholesomeness, with SL 4 and .NET 4.0 Rishi has a post up announcing a new nRoute release for Silverlight 4 and .NET 4.0 He's tweaked the code to take advantages of enhancements in the new platforms, so check it out. Windows Phone 7 Developer Tools April 2010 Refresh Booya... Tim Heuer announced the release of the next drop in the WP7 tools ... dang wish I was at home today :) ... be sure to read the post for info such as the notes about Authenticode Assemblies and the release notes. Updates to Silverlight Multi-binding support Stefan Olson points up a SL4 change to Multi-binding support that he had previously blogged about. He shows the previous non-working example, and what you have to do to make it work now. Using XAML to create a custom wallpaper image for your mobile device David Anson has a solution for those pesky lost devices, and let me go on the record right now saying if anyone finds a WP7 phone laying around, just call me, it's mine :) [think that'd work??] ... ok, David's solution is a WPF app "MobileDeviceHomeScreenMaker" that you get the info set and it produces a png you then put on your device. But seriously about that lost phone... Stay in the 'Light!

• My Mother Bought a Droid

  - by Ben Griswold

  I converted to iPhone two years ago when I left my former employer and my Blackberry behind. The truth is I half-heartedly purchased my iPhone. It was a great looking device, but as far as I was concerned, it was a mere toy compared to my Blackberry.  I remember hiding the toy in my briefcase when attending business meetings because I didn’t consider it to be professional enough.  I’ve since owned all three generations of the iPhone and, well, iPhone seems to have caught on. I still miss the click of the Blackberry keyboard and the blinking red light letting me know that someone/something requires my attention, but I’m officially an iPhone fanboy now.  My mom called last weekend and asked if she should buy an iPhone. I talked her ear off about everything I love about iPhone. I went on for about twenty minutes. I couldn’t help myself. I mentioned everything from my podcast subscriptions to the application which manages my workouts.  I went as far as to say that someday all smart phones will be referred to as iPhones just like all tissues are referred to as Kleenex and all sodas are referred to as Cokes.  I was really on a roll and then I stopped. I had to…the call dropped.  There I was, strategically standing in the far corner of my backyard where I get the most reliable AT&T reception and the call drops in middle of my iPhone pitch.  Folks, I don’t care how good a salesperson you are, it’s tough to recover from a situation like this.   I dialed my mom back and jokingly asked if she was planning to make calls with her new phone. I explained that AT&T is bound to provide better service eventually but I’m not sure she should wait. After all, I have troubles with the network in San Diego and I can only image how bad it would be for her in Western Massachusetts. Mom called back a few days later exclaiming, “I bought a Droid! I love this phone! I haven’t done anything with it but make phone calls, but I love it.”  I had to laugh.  My mom made the right call (pun intended.)  The iPhone is an amazing device, but owners are constantly reminded that its core function (it’s a phone, remember?) is subpar.  If you love gadgets, you’re probably enthralled by iPhone’s many bells and whistles and, relatively speaking, the terrible phone service might not amount to much.  (Maybe it amounts to a rant on your blog.) The overall iPhone offering is so attractive that consumers are willing to wait for AT&T to straighten up their act or wait until Apple grants a choice of carriers.  But I don’t see either of these remedies coming soon. In the interim, I’m willing to take my iPhone for what it is and just continue to enjoy my favorite features while pretending that poor coverage isn’t a big deal. With any luck, more and more reasonable folks will recognize that Android Phones are legitimate players in the smart phone space, they will buy loads of them and there will become plenty of functional phones to borrow when my “phone” is showing zero bars.  Heck, I’m already covered when I visit my mom.

• Home Energy Management & Automation with Windows Phone 7

  A number of people at Clarity are personally interested in home energy conservation and home automation. We feel that a mobile device is a great fit for bringing this idea to fruition. While this project is merely a concept and not directly associated with Microsofts Hohm web service, it provides a great model for communicating the concept. I wanted to take the idea a step further and combine saving energy in your home with the ability to track water usage and control your home devices. I designed an application that focuses on total home control and not just energy usage. Application Overview By monitoring home consumption in real time and with yearly projections users can pinpoint vampire devices, times of high or low consumption, and wasteful patterns of energy use. Energy usage meters indicate total current consumption as well as individual device consumption. Users can then use the information to take action, make adjustments, and change their consumption behaviors. The app can be used to automate certain systems like lighting, temperature, or alarms. Other features can be turned on an off at the touch of a toggle switch on your phone, away from home. Forget to turn off the TV or shut the garage door? No problem, you can do it from your phone. Through settings you can enable and disable features of the phone that apply to your home making it a completely customized and convenient experience. To be clear, this equates to more security, big environmental impact, and even bigger savings.   Design and User Interface  Since this panorama application is designed for win phone 7 devices, it complies with the UI Design and Interaction Guide for wp7. I developed the frame and page hierarchy from existing examples. The interface takes advantage of the interactive nature of touch screens with slider controls, pivot control views, and toggle switches to turn on and off devices (not shown in mockup). I followed recommendations for text based elements and adapted the tile notifications to display the most recent user activity. For example, the mockup indicates upon launching the app that the last thing you did was program the thermostat. This model is great for quick launching common user actions. One last design feature to point out is the technical reasons for supplying both light and dark themes for the app. Since this application is targeting energy consumption it only makes sense to consider the effect of the apps background color or image on the phones energy use. When displaying darker colors like black the OLED display may use less power, extending battery life. Other Considerations For now I left out options of wind and solar powered energy options because they are not available to everyone. Renewable energy sources and new technologies associated with them are definitely ideas to keep in mind for a next iteration. Another idea to explore for such an application would be to include a savings model similar to mint.com. In addition to general energy-saving recommendations the application could recommend customized ways to save based on your current utility providers and available options in your area. If your television or refrigerator is guilty of sucking a lot of energy then you may see recommendations for energy star products that could save you even more money! Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Is Microsoft&rsquo;s Cloud Bet Placed on the Ground?

  - by andrewbrust

  Today at the Unversity of Washington, Steve Ballmer gave a speech on Microsoft’s cloud strategy.  Significantly, Azure was only briefly mentioned and was not shown.  Instead, Ballmer spoke about what he called the five “dimensions” of the cloud, and used that as the basis for an almost philosophical discussion.  Ballmer opined on how the cloud should be distinguished from the Internet.as well as what the cloud will and should enable.  Ballmer worked hard to portray the cloud not as a challenger to Windows and PCs (as Google would certainly suggest it is) but  really as just the latest peripheral that adds value to PCs and devices. At one point during his speech, Ballmer said “We start with Windows at Microsoft.  It’s the most popular smart device on the planet.  And our design center for the future of Windows is to make it one of those smarter devices that the cloud really wants.”  I’m not sure I agree with Ballmer’s ambition here, but I must admit he’s taken the “software + services” concept and expanded on it in more consumer-friendly fashion. There were demos too.  For example, Blaise Aguera y Arcas reprised his Bing Maps demo from the TED conference held last month.  And Simon Atwell showed how Microsoft has teamed with Sky TV in the UK to turn Xbox into something that looks uncannily like Windows Media Center.  Specifically, an Xbox console app called Sky Player provides full access to Sky’s on-demand programming but also live TV access to an array of networks carried on its home TV service, complete with an on-screen programming guide.  Windows Phone 7 Series was shown quickly and Ballmer told us that while Windows Mobile/Phone 6.5 and earlier were designed for voice and legacy functionality, Windows Phone 7 Series is designed for the cloud. Over and over during Ballmer’s talk (and those of his guest demo presenters), the message was clear: Microsoft believes that client (“smart”) devices, and not mere HTML terminals, are the technologies to best deliver on the promise of the cloud.  The message was that PCs running Windows, game consoles and smart phones  whose native interfaces are Internet-connected offer the most effective way to utilize cloud capabilities.  Even the Bing Maps demo conveyed this message, because the advanced technology shown in the demo uses Silverlight (and thus the PCs computing power), and not AJAX (which relies only upon the browser’s native scripting and rendering capabilities) to produce the impressive interface shown to the audience. Microsoft’s new slogan, with respect to the cloud, is “we’re all in.”  Just as a Texas Hold ‘em player bets his entire stash of chips when he goes all in, so too is Microsoft “betting the company” on the cloud.  But it would seem that Microsoft’s bet isn’t on the cloud in a pure sense, and is instead on the power of the cloud to fuel new growth in PCs and other client devices, Microsoft’s traditional comfort zone.  Is that a bet or a hedge?  If the latter, is Microsoft truly all in?  I don’t really know.  I think many people would say this is a sucker’s bet.  But others would say it’s suckers who bet against Microsoft.  No matter what, the burden is on Microsoft to prove this contrarian view of the cloud is a sensible one.  To do that, they’ll need to deliver on cloud-connected device innovation.  And to do that, the whole company will need to feel that victory is crucial.  Time will tell.  And I expect to present progress reports in future posts.

• View Mobile Websites in Windows with Safari 4 Developer Tools

  - by Matthew Guay

  Want to try out mobile websites designed for the iPhone and other mobile devices on your PC?  Safari 4 for Windows lets you do this easily with their developer tools. By default, Safari will show standard desktop websites.  But by making a simple change, you can switch it to work like Safari Mobile on the iPhone or iPod Touch. Getting Started First make sure you have Safari 4 for Windows installed.  You can download Safari directly (link below) and install it as usual.   Or if you already have another Apple program installed, such as QuickTime or iTunes, then you can install it from Apple Software update.  Simply enter apple software update in the Start menu search box. And then select Safari 4 from the list of new software available.  Click Install to automatically download and install Safari. Accept the license Agreement, and then Safari will automatically install. Once this is finished, Safari will be ready to use. View Mobile Sites in Safari First, we need to enable the developer tools.  Click the gear icon on the toolbar, and select Preferences. Click the Advanced tab, and then check the box that says “Show Develop menu in menu bar”. Once you’ve closed your settings box, click the page icon, select Develop, then User Agent, and then choose one of the Mobile Safari settings.  In our test we chose Mobile Safari 3.1.2 – iPhone. To make your browser emulate a mobile device better, you can hide the bookmarks and tab bar to have a more streamlined interface. Click the Gear icon, and select “Hide Bookmarks Bar”, and then repeat and click “Hide Tab Bar”. You can also shrink your window to be closer to the size of a mobile device screen.  Once you’ve done these things, Safari should look similar to this screenshot.  Here we have loaded Google.com, and you can see it in its iPhone-style interface. Simply enter any website into the address bar, and it will load in its mobile interface if it has one.  Here is Google’s other mobile offerings, right inside Windows. Gmail loads messages with the default iPhone interface. One especially interesting mobile site is Apple’s online iPhone User Guide.  When loaded in Safari with the iPhone setting, it loads with a very nice mobile UI that works just like an iPhone app.  In fact, you can even click and drag to scroll, just like you would with your finger on an iPhone. Conclusion Even if you do not have a Smartphone, you can still preview what websites will look like on them with this trick. Not all sites will work of course, but it’s fun to play around with different sites that have mobile versions.

• Converting an Oracle VM VirtualBox VM into an Oracle VM Server image

  - by wim.coekaerts

  As we are working on tighter seemless moving of VM's between the 2 products, here are a few simple steps to convert an existing Oracle VM VirtualBox image over. Steps involved to make it easy/straightforward : (1) When creating a VM in Virtualbox, using Oracle Linux as an example, make sure that /etc/fstab only uses labels. Do not use hardcoded device names. instead of an entry /dev/sda1 /u01 ext3 defaults 1 1 use LABEL=foo /u01 ext3 defaults 1 1 for more info on labels : man e2label or use a logical volume /dev/VolGroup00/LVfoo /u01 ext3 defaults 1 1 Doing so will make it easier to have an OS boot up on a different hypervisor with potentially different device names. For instance, the VirtualBox VM might expose a scsi driver while in Oracle VM Server you might end up with an ide disk, this then changes /dev/sda to /dev/hda. (2) If you have a VM created that you want to convert, then shut down the VM in VirtualBox and convert the image files : go the the directory that contains your HardDisk image files (.VirtualBox/HardDisks/* as an example) for each of the virtual disks run the following command : VBoxManage clonehd virtualdiskfilename.vdi system.img --format raw where virtualdiskfilename.vdi is the original VBox VM file (this can also be a vmdk file) and system.img is the name of the virtualdisk for Oracle VM. this can be any filename as well, I typically use system.img to specify the boot disk (as is common for Oracle VM template creation) (3) create a vm.cfg To run a VM converted from VirtualBox, you have to create a vm.cfg for Oracle VM server that creates an HVM guest. The easiest is to use a simple hvm vm.cfg and change it for your vm. I have an example here : acpi = 1 apic = 1 builder = 'hvm' device_model = '/usr/lib/xen/bin/qemu-dm' disk = ['file:system.img,hda,w', 'file:oracle.img,hdb,w',',hdc:cdrom,r',] kernel = '/usr/lib/xen/boot/hvmloader' memory = '1024' name = 'vmname' on_crash = 'restart' on_reboot = 'restart' pae = 1 serial = 'pty' timer_mode = '0' usbdevice = 'tablet' vcpus = 1 vif = ['bridge=xenbr0,type=ioemu'] vif_other_config = [] vnc = 1 vncconsole = 1 vnclisten = '0.0.0.0' vncpasswd = '' vncunused = 1 If you take the above vm.cfg, all you need to do - modify disk = (add your virtual disks in there) - modify memory = (amount of memory your VM needs) - modify name = (enter a name for your VM here) - modify vif = (might want to replace bridge=xenbr0 to the bridge you want to use) if you want more than 1 vcpu or other changes of course you have to make those as well. (4) copy this set of files onto your Oracle VM server or onto a webserver in a subdirectory and import the template through Oracle VM Manager. You can also just start the vm using xm create vm.cfg if you like. And that's it. As I said, we are working on automation around all this but it is relatively trivial to convert VM's over as long as you take the basic issues into account. Primarily the set up of the filesystems and the use of labels in /etc/fstab. There are other potential things to look at, such as network config. If you want to make that part clean then prior to shutting down the VM change /etc/modprobe.conf and/or add the mac address of the VM into the vm.cfg in the vifs line. The good thing, at least with Linux, is that even tho the virtual hardware changes, Linux will deal with it just fine (e1000 vs 8139 realtek, ide vs scsi etc). hope this helps.

• Wireless internet is connected to an open network but has no internet

  - by Joshua Reeder

  I just installed Ubuntu on my laptop yesterday and it connected to the wireless fine. Then I took it to school, put it on their wired connection, downloaded some stuff, and now the wireless doesn't work. At first it would detect networks, but not connect. I restarted it and now it can connect, but it acts like it doesn't have internet in the browser. Wired connection still works fine on it. I know it isn't the network because my ipad is working on the wireless connection fine. I found another solution on here switching the security settings for the wireless, but this is the apartment's wireless so they have it open, and I won't be able to mess with it at all.
