  • How to Set Up Your Enterprise Social Organization

    - by Mike Stiles
    The rush for business organizations to establish, grow, and adopt social was driven out of necessity and inevitability. The result, however, was a sudden, booming social presence creating touch points with customers, partners and influencers, but without any corporate social organization or structure in place to effectively manage it. Even today, many business leaders remain uncertain as to how to corral this social media thing so that it makes sense for their enterprise. Imagine their panic when they hear one of the most beneficial approaches to corporate use of social involves giving up at least some hierarchical control and empowering employees to publicly engage customers. And beyond that, they should also be empowered, regardless of their corporate status, to engage and collaborate internally, spurring “off the grid” innovation. An HBR blog points out that traditionally, enterprise organizations function from the top down, and employees work end-to-end, structured around business processes. But the social enterprise opens up structures that up to now have not exactly been embraced by turf-protecting executives and managers. The blog asks, “What if leaders could create a future where customers, associates and suppliers are no longer seen as objects in the system but as valued sources of innovation, ideas and energy?” What if indeed? The social enterprise activates internal resources without the usual obsession with position. It is the dawn of mass collaboration. That does not, however, mean this mass collaboration has to lead to uncontrolled chaos. In an extended interview with Oracle, Altimeter Group analyst Jeremiah Owyang and Oracle SVP Reggie Bradford paint a complete picture of today’s social enterprise, including internal organizational structures Altimeter Group has seen emerge. One sign of a mature social enterprise is the establishing of a social Center of Excellence (CoE), which serves as a hub for high-level social strategy, training and education, research, measurement and accountability, and vendor selection. This CoE is led by a corporate Social Strategist, most likely from a Marketing or Corporate Communications background. Reporting to them are the Community Managers, the front lines of customer interaction and engagement; business unit liaisons that coordinate the enterprise; and social media campaign/product managers, social analysts, and developers. With content rising as the defining factor for social success, Altimeter also sees a Content Strategist position emerging. Across the enterprise, Altimeter has seen 5 organizational patterns. Watching the video will give you the pros and cons of each. Decentralized - Anyone can do anything at any time on any social channel. Centralized – One central groups controls all social communication for the company. Hub and Spoke – A centralized group, but business units can operate their own social under the hub’s guidance and execution. Most enterprises are using this model. Dandelion – Each business unit develops their own social strategy & staff, has its own ability to deploy, and its own ability to engage under the central policies of the CoE. Honeycomb – Every employee can do social, but as opposed to the decentralized model, it’s coordinated and monitored on one platform. The average enterprise has a whopping 178 social accounts, nearly ¼ of which are usually semi-idle and need to be scrapped. The last thing any C-suite needs is to cope with fragmented technologies, solutions and platforms. It’s neither scalable nor strategic. The prepared, effective social enterprise has a technology partner that can quickly and holistically integrate emerging platforms and technologies, such that whatever internal social command structure you’ve set up can continue efficiently executing strategy without skipping a beat. @mikestiles

  • Archiving SQLHelp tweets

    - by jamiet
    #SQLHelp is a Twitter hashtag that can be used by any Twitter user to get help from the SQL Server community. I think its fair to say that in its first year of being it has proved to be a very useful resource however Kendra Little (@kendra_little) made a very salient point yesterday when she tweeted: Is there a way to search the archives of #sqlhelp Trying to remember answer to a question I know I saw a couple months ago http://twitter.com/#!/Kendra_Little/status/15538234184441856 This highlights an inherent problem with Twitter’s search capability – it simply does not reach far enough back in time. I have made steps to remedy that situation by putting into place two initiatives to archive Tweets that contain the #sqlhelp hashtag. The Archivist http://archivist.visitmix.com/ is a free service that, quite simply, archives a history of tweets that contain a given search term by periodically polling Twitter’s search service with that search term and subsequently displaying a dashboard providing an aggregate view of those tweets for things like tweet volume over time, top users and top words (Archivist FAQ). I have set up an archive on The Archivist for “sqlhelp” which you can view at http://archivist.visitmix.com/jamiet/7. Here is a screenshot of the SQLHelp dashboard 36 minutes after I set it up: There is lots of good information in there, including the fact that Jonathan Kehayias (@SQLSarg) is the most active SQLHelp tweeter (I suspect as an answerer rather than a questioner ) and that SSIS has proven to be a rather (ahem) popular subject!! Datasift The Archivist has its uses though for our purposes it has a couple of downsides. For starters you cannot search through an archive (which is what Kendra was after) and nor can you export the contents of the archive for offline analysis. For those functions we need something a bit more heavyweight and for that I present to you Datasift. Datasift is a tool (currently an alpha release) that allows you to search for tweets and provide them through an object called a Datasift stream. That sounds very similar to normal Twitter search though it has one distinct advantage that other Twitter search tools do not – Datasift has access to Twitter’s Streaming API (aka the Twitter Firehose). In addition it has access to a lot of other rather nice features: It provides the Datasift API that allows you to consume the output of a Datasift stream in your tool of choice (bring on my favourite ultimate mashup tool J ) It has a query language (called Filtered Stream Definition Language – FSDL for short) A Datasift stream can consume (and filter) other Datasift streams Datasift can (and does) consume services other than Twitter If I refer to Datasift as “ETL for tweets” then you may get some sort of idea what it is all about. Just as I did with The Archivist I have set up a publicly available Datasift stream for “sqlhelp” at http://datasift.net/stream/1581/sqlhelp. Here is the FSDL query that provides the data: twitter.text contains "sqlhelp" Pretty simple eh? At the current time it provides little more than a rudimentary dashboard but as Datasift is currently an alpha release I think this may be worth keeping an eye on. The real value though is the ability to consume the output of a stream via Datasift’s RESTful API, observe: http://api.datasift.net/stream.xml?stream_identifier=c7015255f07e982afdeebdf1ae6e3c0d&username=jamiet&api_key=XXXXXXX (Note that an api_key is required during the alpha period so, given that I’m not supplying my api_key, this URI will not work for you) Just to prove that a Datasift stream can indeed consume data from another stream I have set up a second stream that further filters the first one for tweets containing “SSIS”. That one is at http://datasift.net/stream/1586/ssis-sqlhelp and here is the FSDL query: rule "414c9845685ff8d2548999cf3162e897" and (interaction.content contains "ssis") When Datasift moves beyond alpha I’ll re-assess how useful this is going to be and post a follow-up blog. @Jamiet

  • Combining Scrum, TFS2010 and Email to keep everyone in the loop

    - by Martin Hinshelwood
    Often you will receive rich information from your Product Owner (Customer) about tasks. That information can be in the form of Word documents, HTML Emails and Pictures, but you generally receive them in the context of an Email. You need to keep these so your Team can refer to it later, and so you can send a “done” when the task has been completed. This preserves the “history” of the task and allows you to keep relevant partied included in any future conversation. At SSW we keep the original email so that we can reply Done and delete the email. But keeping it in your email does not help other members of the team if they complete the task and need to send the “done”. Worse yet, the description field in Team Foundation Server 2010 (TFS 2010) does not support HTML and images, nor does the default task template support an “interested parties” or CC field. You can attach this content manually, but it can be time consuming. Figure: Description only supports plain text, and History supports HTML with no images   What should we do? At SSW we always follow the rules, and it just so happened that we have rules to both achieve this, and to make it easier. You should follow the existing Rules to Better Project Management  and attach the email to your task so you can refer to and reply to it later when you close the task: Do you know what Outlook add-ins you need? Describe the work item request in an email Use Outlook Add-in to move the email to a TFS Work Item When replying to an email with “done” you should follow: Do you update Team Companion template, so the email "subject" doesn't change? Do you update Team Companion template, so you can generate a proper "done" mail? Following these simple rules will help your Product Owner understand you better, and allow your team to more effectively collaborate with each other. An added bonus is that as we are keeping the email history in sync with TFS. When you “reply all” to the email all of the interested partied to the Task are also included. This notified those that may have been blocked by your task to keep up to date with its status. This has been published as Do you know to ensure that relevant emails are attached to tasks in our Rules to Better Scrum using TFS. What could we do better? I would like to see this process automated so that we capture the information correctly in the task without the need to use email. This would require a change to the process template in Team Foundation Server to add an “Interested Parties” field. Each reply to the email would need to be automatically processed into a Work Item. This could be done by adding a task identifier as the first item in the “Relates to” email header, and copying in an email address that you watch. This would then parse out the relevant information and add the new message to the history, update the “Interested parties” field and attach the Images. Upon reflection, it may even be possible, but more difficult to do this using ONLY the History field and including some of the header information in there to the build a done email with history. This would not currently deal with email “forks” well, but I think it would be adequate for our needs. It would be nice if we could find time to implement this, but currently it is but a pipe dream. Maybe Microsoft could implement something in the next version of Team Foundation Server, and in the mean time we have a process that works well. Technorati Tags: Scrum,SSW Rules,TFS 2010,TFS 2008

  • Changes in licence in forked project what are my rights?

    - by Wes
    Hi I'm intrested in using the apparently now defunct app-mdi libray in a flex application for a paying customer. http://sourceforge.net/projects/appmdi/ It appears that the app-mdi project has been forked from flex-mdi and indeed the code has so much in common it would appear almost identical to the origional code. Now in the original source flex-mdi the following licence appears in the source code /* Copyright (c) 2007 FlexMDI Contributors. See: http://code.google.com/p/flexmdi/wiki/ProjectContributors Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution. The copyright notice in its entireity makes no sense in binary material. Specifically talking about redistobutions in the binary form. Finally the question is what exactly has to be shown on web clients who access softare that utilises this library? Also is changing the licence in this manner actually allowed?

  • How to Set Up Your Enterprise Social Organization?

  • EnOcean -> USB Serial Communication (C++)

    - by regorianer
    I guess it is not the right place to ask here for enocean specific details, but maybe I am doing something wrong by using serial connections and you can help me no matter if there is knowledge about this technology or not. I have a problem to communicate with the RCM152 Module. I have written a C++ program to communicate with the RCM152 by emulating packets of the PTM 200. I teach the RCM152 to listen to the following packets: [06/19/12 04:21:44.546] INFO: SENDING BYTE : 55 <-- start byte [06/19/12 04:21:44.546] INFO: SENDING BYTE : 00 <-- head begin [06/19/12 04:21:44.546] INFO: SENDING BYTE : 07 [06/19/12 04:21:44.546] INFO: SENDING BYTE : 07 [06/19/12 04:21:44.546] INFO: SENDING BYTE : 01 <-- head end [06/19/12 04:21:44.546] INFO: SENDING BYTE : 7a <-- CRC Check [06/19/12 04:21:44.546] INFO: SENDING BYTE : f6 <-- packet type [06/19/12 04:21:44.546] INFO: SENDING BYTE : 20 <-- My action (00 and 10 -> OFF, 20 and 30 -> ON) [06/19/12 04:21:44.546] INFO: SENDING BYTE : 00 <-- serial.byte 3 [06/19/12 04:21:44.546] INFO: SENDING BYTE : 24 <-- serial.byte 2 [06/19/12 04:21:44.546] INFO: SENDING BYTE : 21 <-- serial.byte 1 [06/19/12 04:21:44.546] INFO: SENDING BYTE : 87 <-- serial.byte 0 [06/19/12 04:21:44.546] INFO: SENDING BYTE : 30 <-- status [06/19/12 04:21:44.546] INFO: SENDING BYTE : 03 <-- 03 for send, 01 for receiver [06/19/12 04:21:44.546] INFO: SENDING BYTE : ff <-- begin destination [06/19/12 04:21:44.546] INFO: SENDING BYTE : ff [06/19/12 04:21:44.546] INFO: SENDING BYTE : ff [06/19/12 04:21:44.546] INFO: SENDING BYTE : ff <-- end destination [06/19/12 04:21:44.546] INFO: SENDING BYTE : ff <-- Transmission quality (sender ff) [06/19/12 04:21:44.546] INFO: SENDING BYTE : 00 [06/19/12 04:21:44.547] INFO: SENDING BYTE : 10 <-- CRC Check A PTM200 Device or a SG-FUS-24-230 Device are sending equivalent packets like: [06/19/12 04:30:31.106] INFO: Received Byte: 55 [06/19/12 04:30:31.106] INFO: Received Byte: 00 [06/19/12 04:30:31.106] INFO: Received Byte: 07 [06/19/12 04:30:31.106] INFO: Received Byte: 07 [06/19/12 04:30:31.106] INFO: Received Byte: 01 [06/19/12 04:30:31.106] INFO: Received Byte: 7a [06/19/12 04:30:31.106] INFO: Received Byte: f6 [06/19/12 04:30:31.106] INFO: Received Byte: 40 [06/19/12 04:30:31.106] INFO: Received Byte: 00 [06/19/12 04:30:31.106] INFO: Received Byte: 24 [06/19/12 04:30:31.106] INFO: Received Byte: 6c [06/19/12 04:30:31.106] INFO: Received Byte: 2f [06/19/12 04:30:31.106] INFO: Received Byte: 30 [06/19/12 04:30:31.106] INFO: Received Byte: 01 [06/19/12 04:30:31.106] INFO: Received Byte: ff [06/19/12 04:30:31.106] INFO: Received Byte: ff [06/19/12 04:30:31.108] INFO: Received Byte: ff [06/19/12 04:30:31.108] INFO: Received Byte: ff [06/19/12 04:30:31.108] INFO: Received Byte: 37 [06/19/12 04:30:31.108] INFO: Received Byte: 00 [06/19/12 04:30:31.108] INFO: Received Byte: d1 I can control the device connected to the RCM152 like I want to with my sending packets (thats a good fact and means that the RCM152 has learned my packets and can use them.

I only want to have actions if the teached-in serial is send and all other packets with different serials to be ignored. The RCM152 is not reacting to the packets sent by the PTM200 nor by the SG-FUS-24-230 because these are not teached-in. Thats exactly what I want to have with the packets created myself. What am I doing wrong? The libraries I am using are these for C++ http://pvbrowser.de/pvbrowser/sf/manual/rllib/html/ The enocean EEP says: For this purpose of a determined relationship between transmitter and receiver each transmitting device has a unique Sender-ID which is part of each radio telegram. The receiving device detects from the Sender-ID whether the device is known, i.e., was already learned, or unknown. A telegram with unknown Sender-ID is disregarded.

  • MIXing it Up a Bit

    - by andrewbrust
    Another March, another MIX.  For the fifth year running now, Microsoft has chosen to put on a conference aimed less at software development, per se, and more at the products, experiences and designs that software development can generate.  In all four prior MIX events, the focus of the show, its keynotes and breakout sessions has been on Web products.  On day 1 of MIX 2010 that focus shifted to Windows Phone 7 Series (WP7). What little we had seen of WP7 had been shown to us in a keynote presentation, given by Microsoft’s Joe Belfiore, at the Mobile World Congress in Barcelona, Spain last month.  And today, Mr. Belfiore reprised his showmanship for the MIX 2010 audience.  Joe showed us the ins and outs of WP7 and, in a breakout session, even gave us a sneak peek of Office (specifically, Excel) on WP7.  We didn’t get to see that one month ago in Barcelona, nor did get to see email messages opened for reading, which we saw today. But beyond a tour of the phone itself, impressive though that is, we got to see apps running on it.  Those apps included Associated Press news, Seesmic (a major Twitter client) and Foursquare (a social media darling).  All three ran, ran well, and looked markedly different and better from their corresponding versions on iPhone and Android.  And the games we saw looked even better. To me though, the best demos involved the creation of WP7 apps, using Silverlight in Visual Studio and Expression Blend.  These demos were so effective because they showed important apps being built in very few steps, and by Microsoft executives to boot.  Scott Guthrie showed us how to build a Twitter API app in Visual Strudio.   Jon Harris showed us how to build a photo management and viewer application in Expression Blend, using virtually no code.  Demos of apps built from scratch to F5 without the benefit of a teacher, could be challenging.  But they went off fine, without a hitch and without a ton of opaque, generated code.  Everything written, be it C# or XAML, was easily understood, and the results were impressive. That means lots of developers can do this, and I think it means a lot will.  What I’ve seen, thus far, of iPhone and Android development looks very tedious by comparison.  Development for those platforms involve a collection of tools that integrate only to a point.  Dev work for WP7 involves use of Visual Studio, Silverlight and the same debugging experience .NET developers already know.  This was very exciting for me. All the demos harkened back to days of building apps for with Visual Basic…design the front-end, put in code-behind and then hit F5.  And that makes sense, because the phone platform, and the PC of the early 90s are both, essentially, client OS machines.  The Web was minimal and the “device” was everything. Same is true of this phone.  It’s a client app contraption that fits in your pocket. And if the platforms are comparable, hopefully so too will be the draw of ease-of-development.   WP7 has the potential to make mobile developers want to switch over, and to convince enterprise developers to get into the phone scene.  Will this propel the new phone platform to new heights, and restore Microsoft’s competiveness in the mobile arena? I hope so.  I think so.  And if Microsoft uses developers to build themselves a victory, that would be beneficial and would show that Microsoft has learned from its failures, as well as its successes.  Today I saw a few beautiful apps.  Tomorrow I hope I see a slew of others; maybe not as polished, but plentiful, attractive and stable.  That would be a victory for Microsoft, and for developers.  And it would show everyone else that developers are the kingmakers.  They need cheap, efficient dev tools and lots of respect.  Microsoft has always been the company to provide that.  Hopefully, with WP7, they will return to that persona and see how very timeless it is.

  • Healthcare and Distributed Data Don't Mix

    - by [email protected]
    How many times have you heard the story?  Hard disk goes missing, USB thumb drive goes missing, laptop goes missing...Not a week goes by that we don't hear about our data going missing...  Healthcare data is a big one, but we hear about credit card data, pricing info, corporate intellectual property...  When I have spoken at Security and IT conferences part of my message is "Why do you give your users data to lose in the first place?"  I don't suggest they can't have access to it...in fact I work for the company that provides the premiere data security and desktop solutions that DO provide access.  Access isn't the issue.  'Keeping the data' is the issue.We are all human - we all make mistakes... I fault no one for having their car stolen or that they dropped a USB thumb drive. (well, except the thieves - I can certainly find some fault there)  Where I find fault is in policy (or lack thereof sometimes) that allows users to carry around private, and important, data with them.  Mr. Director of IT - It is your fault, not theirs.  Ms. CSO - Look in the mirror.It isn't like one can't find a network to access the data from.  You are on a network right now.  How many Wireless ones (wifi, mifi, cellular...) are there around you, right now?  Allowing employees to remove data from the confines of (wait for it... ) THE DATA CENTER is just plain indefensible when it isn't required.  The argument that the laptop had a password and the hard disk was encrypted is ridiculous.  An encrypted drive tells thieves that before they sell the stolen unit for $75, they should crack the encryption and ascertain what the REAL value of the laptop is... credit card info, Identity info, pricing lists, banking transactions... a veritable treasure trove of info people give away on an 'encrypted disk'.What started this latest rant on lack of data control was an article in Government Health IT that was forwarded to me by Denny Olson, an Oracle Principal Sales Consultant in Minnesota.  The full article is here, but the point was that a couple laptops went missing in a couple different cases, and.. well... no one knows where the data is, and yes - they were loaded with patient info.  What were you thinking?Obviously you can't steal data form a Sun Ray appliance... since it has no data, nor any storage to keep the data on, and Secure Global Desktop allows access from Macs, Linux and Windows client devices...  but in all cases, there is no keeping the data unless you explicitly allow for it in your policy.   Since you can get at the data securely from any network, why would you want to take personal responsibility for it?  Both Sun Rays and Secure Global Desktop are widely used in Healthcare... but clearly not widely enough.We need to do a better job of getting the message out -  Healthcare (or insert your business type here) and distributed data don't mix. Then add Hot Desking and 'follow me printing' and you have something that Clinicians (and CSOs) love.Thanks for putting up my blood pressure, Denny.

  • Skewed: a rotating camera in a simple CPU-based voxel raycaster/raytracer

    - by voxelizr
    TL;DR -- in my first simple software voxel raycaster, I cannot get camera rotations to work, seemingly correct matrices notwithstanding. The result is skewed: like a flat rendering, correctly rotated, however distorted and without depth. (While axis-aligned ie. unrotated, depth and parallax are as expected.) I'm trying to write a simple voxel raycaster as a learning exercise. This is purely CPU based for now until I figure out how things work exactly -- fow now, OpenGL is just (ab)used to blit the generated bitmap to the screen as often as possible. Now I have gotten to the point where a perspective-projection camera can move through the world and I can render (mostly, minus some artifacts that need investigation) perspective-correct 3-dimensional views of the "world", which is basically empty but contains a voxel cube of the Stanford Bunny. So I have a camera that I can move up and down, strafe left and right and "walk forward/backward" -- all axis-aligned so far, no camera rotations. Herein lies my problem. Screenshot #1: correct depth when the camera is still strictly axis-aligned, ie. un-rotated. Now I have for a few days been trying to get rotation to work. The basic logic and theory behind matrices and 3D rotations, in theory, is very clear to me. Yet I have only ever achieved a "2.5 rendering" when the camera rotates... fish-eyey, bit like in Google Streetview: even though I have a volumetric world representation, it seems --no matter what I try-- like I would first create a rendering from the "front view", then rotate that flat rendering according to camera rotation. Needless to say, I'm by now aware that rotating rays is not particularly necessary and error-prone. Still, in my most recent setup, with the most simplified raycast ray-position-and-direction algorithm possible, my rotation still produces the same fish-eyey flat-render-rotated style looks: Screenshot #2: camera "rotated to the right by 39 degrees" -- note how the blue-shaded left-hand side of the cube from screen #2 is not visible in this rotation, yet by now "it really should"! Now of course I'm aware of this: in a simple axis-aligned-no-rotation-setup like I had in the beginning, the ray simply traverses in small steps the positive z-direction, diverging to the left or right and top or bottom only depending on pixel position and projection matrix. As I "rotate the camera to the right or left" -- ie I rotate it around the Y-axis -- those very steps should be simply transformed by the proper rotation matrix, right? So for forward-traversal the Z-step gets a bit smaller the more the cam rotates, offset by an "increase" in the X-step. Yet for the pixel-position-based horizontal+vertical-divergence, increasing fractions of the x-step need to be "added" to the z-step. Somehow, none of my many matrices that I experimented with, nor my experiments with matrix-less hardcoded verbose sin/cos calculations really get this part right. Here's my basic per-ray pre-traversal algorithm -- syntax in Go, but take it as pseudocode: fx and fy: pixel positions x and y rayPos: vec3 for the ray starting position in world-space (calculated as below) rayDir: vec3 for the xyz-steps to be added to rayPos in each step during ray traversal rayStep: a temporary vec3 camPos: vec3 for the camera position in world space camRad: vec3 for camera rotation in radians pmat: typical perspective projection matrix The algorithm / pseudocode: // 1: rayPos is for now "this pixel, as a vector on the view plane in 3d, at The Origin" rayPos.X, rayPos.Y, rayPos.Z = ((fx / width) - 0.5), ((fy / height) - 0.5), 0 // 2: rotate around Y axis depending on cam rotation. No prob since view plane still at Origin 0,0,0 rayPos.MultMat(num.NewDmat4RotationY(camRad.Y)) // 3: a temp vec3. planeDist is -0.15 or some such -- fov-based dist of view plane from eye and also the non-normalized, "in axis-aligned world" traversal step size "forward into the screen" rayStep.X, rayStep.Y, rayStep.Z = 0, 0, planeDist // 4: rotate this too -- 0,zstep should become some meaningful xzstep,xzstep rayStep.MultMat(num.NewDmat4RotationY(CamRad.Y)) // set up direction vector from still-origin-based-ray-position-off-rotated-view-plane plus rotated-zstep-vector rayDir.X, rayDir.Y, rayDir.Z = -rayPos.X - me.rayStep.X, -rayPos.Y, rayPos.Z + rayStep.Z // perspective projection rayDir.Normalize() rayDir.MultMat(pmat) // before traversal, the ray starting position has to be transformed from origin-relative to campos-relative rayPos.Add(camPos) I'm skipping the traversal and sampling parts -- as per screens #1 through #3, those are "basically mostly correct" (though not pretty) -- when axis-aligned / unrotated.

  • How to switch between views in android?

    - by aurezza
    I've tried several methods to switch between two views in my program. I've tried creating a new thread then have the view run for 5 seconds before creating intent to start my main activity. This is the code snippet from the said view class: mHelpThread = new Thread(){ @Override public void run(){ try { synchronized(this){ // Wait given period of time or exit on touch wait(5000); } } catch(InterruptedException ex){ } finish(); // Run next activity Intent intent = new Intent(Intent.ACTION_MAIN, null); intent.addCategory(Intent.CATEGORY_HOME); startActivity(intent); //stop(); } }; mHelpThread.start(); I can access the said view without error but it doesn't disappear after 5 seconds nor did it switched to main view when I even utilized an onTouchEvent() to detect touch on the screen of which it should have automatically closed. I've also tried adding a button on the said view to manually switch to main view: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.help); final HelpView helpView = this; final Button btnback = (Button) findViewById(R.id.back); btnback.setOnClickListener(new View.OnClickListener(){ public void onClick(View v) { Intent intent = new Intent(helpView, MainActivity.class); startActivity(intent); } }); } These codes worked, though, for creating a launcher for my program. So I thought that it would work the same if I added an option for help/rules(for the game) that would switch to another view. I've only since started using eclipse for android so pardon my lack of knowledge. Here is also the snippet from my manifest: <uses-sdk android:minSdkVersion="11" android:targetSdkVersion="15" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="MainActivity" android:label="@string/title_activity_main"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.DEFAULT"/> </intent-filter> <intent-filter></intent-filter> </activity> <activity android:name="SplashScreen" android:theme="@style/Theme.Transparent"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> <activity android:name="HelpView" android:theme="@style/Theme.Transparent"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.DEFAULT"/> </intent-filter> <intent-filter></intent-filter> </activity> </application>

  • Are there too many qualified software development engineers chasing too few jobs?

    - by T Gregory
    I am trying to write this question in a non-argumentative way, but it is quite emotionally charged for some, so please bear with me. In the U.S., we hear constantly from CEOs that they cannot find enough qualified software engineers. In fact, it is the position of the U.S. government that demand for software engineering talent outpaces supply. This position can be clearly seen in the granting of tens of thousands of H1B visas, but also in the following excerpt from the official 2010-11 Bureau of Labor Statistics Occupational Outlook Handbook: Employment of computer software engineers is expected to increase by 32 percent from 2008-2018, which is much faster than the average for all occupations. In addition, this occupation will see a large number of new jobs, with more than 295,000 created between 2008 and 2018. Demand for computer software engineers will increase as computer networking continues to grow. For example, expanding Internet technologies have spurred demand for computer software engineers who can develop Internet, intranet, and World Wide Web applications. Likewise, electronic data-processing systems in business, telecommunications, healthcare, government, and other settings continue to become more sophisticated and complex. Implementing, safeguarding, and updating computer systems and resolving problems will fuel the demand for growing numbers of systems software engineers. New growth areas will also continue to arise from rapidly evolving technologies. The increasing uses of the Internet, the proliferation of Web sites, and mobile technology such as the wireless Internet have created a demand for a wide variety of new products. As more software is offered over the Internet, and as businesses demand customized software to meet their specific needs, applications and systems software engineers will be needed in greater numbers. In addition, the growing use of handheld computers will create demand for new mobile applications and software systems. As these devices become a larger part of the business environment, it will be necessary to integrate current computer systems with this new, more mobile technology. However, from the the employee side of the equation, we often hear the opposite. Many of the stories of SDEs with graduate degrees and decades of experience on the unemployment line, or the big tech interview war stories, are anecdotal, for sure. But, there is one piece of data that is neither anecdotal nor transitory, and that is the aggregate decisions of millions of undergraduates of what degree to pursue. Here, a different picture emerges from the data, and that picture is not good for the software profession. According the most recent Taulbee Survey from Computer Research Association, undergrad degree production in CS and CE has fallen nearly 60% since 2004. (Undergrad enrollments have ticked up in the past two years, but only modestly). Here we see that a basic disconnect between what corporate CEOs and the US government are saying and what potential employees really think about job prospects in software engineering. So my questions are these. Who are we to believe? Is there an acute talent shortage, or is there a long-term structural oversupply in the SDE labor market? Can anyone provide reliable data on long-term unemployment among SDEs? How many are leaving the profession due to lack of work? Real data is most helpful. Thanks.

  • Laptop screen blank after login when external monitor is not connected

    - by Ramon Suarez
    Ubuntu does not switch back automatically to only monitor present when booting after disconnecting external monitor. Here's a video showing what happens. I get to the login window and everything looks ok, then I type my password, the desktop image shows up and... everything goes blank. It does not happen when I just login as a guest. When possible I work with my laptop connected to an external screen via the VGA port. The problem comes when I boot the computer without that secondary screen connected: The login screen comes out ok. After login the screen goes black, but I can hear the login sound. If I hit ctr + alt + backwards-delete and login again sometimes it is fixed, but not all. If I log in as a different user everything is OK. Then I log in as my user and sometimes it works. To have a screen I have to plug a monitor. Although I have turned on the laptop display with that monitor on, if I reboot it goes blank again after login, even if I turn off the external monitor before turning off the computer. I've managed to get my screen back with my username after going into recovery mode, but only sometimes. Failsafe would not load after second screen asking me what I wanted to do (no mouse to click nor keyboard working). My computer is a LDLC Aurore BB1-i5 -8 -S1. Which is the configuration file that keeps the information about the monitors using Displays under lightgdm and where is it? I guess if I could edit it I may have a chance :) One of the things I tried following a solution in another post was removing my monitors.xml file, but it does not work and I don't know how to create a good one that I could use now. When doing DISPLAY=:0 xrandrI get: Screen 0: minimum 320 x 200, current 320 x 200, maximum 8192 x 8192 LVDS1 connected (normal left inverted right x axis y axis) 1366x768 60.0 + 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) This is the full dmesg after activating sudo xdiagnoseas Bryce sugested. (If you tell me the relevant parts I will paste them here) When conecting the external monitor, only the external will work, although I can see using Displays that the computer thinks that both are working. I've asked the question in Launchpad but have it keeps on expiring without any feedback. In my opinion Ubuntu should be able to detect automatically that there is no external monitor present and switch to the laptop monitor. There's a similar question here, but it does not apply to my case External monitor set as primary even when disconnected from laptop Update: For clarification, the problem happens only with my user and once I log in. I even get to see the screensaver for about a second, and then it goes blank. Tried Bryce's example (see his answer below), but it did not work. This is the info I get from tty1 with Display=:0 xrandr: – Ramon Suarez Jul 9 at 16:36 Screen 0: minimum 320 x 200, current 320 x 200, maximum 8192 x 8192 LVDS1 connected (normal left inverted right x axis y axis) 1366x768 60.0 + 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis)

  • Ubuntu Server 12 not spawning a serial ttyS0 when running on Xen

    - by segfaultreloaded
    I have this problem on more than one host, so the specific hardware is not an issue. Bare metal Ubuntu 12 is not creating a login process on the only serial port, in the default configuration. The serial port works correctly with the firmware. It works correctly with Grub2.

  • Taking Your Business Scorecard Golfing

    - by tobyehatch
    Our workplace world is definitely changing. Not only are we taking work home, but we are working during odd hours in some very strange places.  I had the pleasure of interviewing Jacques Vigeant, Product Strategy Manager for Oracle Business Intelligence and Enterprise Performance Management, on a Podcast, and he enlightened me about how our mobile devices and business scorecards are enabling us to be more accountable and keep a watchful eye on business – even while on the golf course.Business scorecards have been around for many years - so I asked Jacques if he felt they had changed significantly due to technology. His answer was, “Yes, and no.”  Jacques agreed that scorecard enthusiasts are still passionate about executing the company strategy and monitoring Key Performance Indicators (KPIs), but scorecards and Business Intelligence (BI) as a whole have changed.  He explained that five to six years ago, people did BI work at the office and, for the most part, disconnected from their computer and workplace when they went home – with the exception of checking email and making a phone call or two. But now, that is no longer the case. People are virtually always connected with work and, more importantly, expect their BI and scorecards to be ‘always on,’ regardless of whether they are at their desk or somewhere else.Basically, the BI paradigm has changed from a 'pull' model, where employees are at their desks querying or pulling information from the system, to a 'push' model where employees expect their BI and scorecard systems to reach out (or push information) to them when there is something of note to learn or something on which they need to take action. I found this very interesting. However mobile devices do have their limitations with respect to screen sizes – does it really make sense to look at your strategy/scorecard on tiny devices? What kind of scorecard activities can you really expect to be able to do? Jacques’ answer was very logical. “When you think of a scorecard, it is really comprised of an organization of KPIs that are aligned with the strategic objectives of your company. KPIs are the heart of how you will execute your strategy. So, if you decompose that a little more, each KPI is well defined with the thresholds that you should keep an eye on and who is responsible for them. When we talk about scorecarding on a phone, we aren’t talking about surfing the strategy and exploring the strategy map like we do on the desktop. In a scorecarding context, we use the phone more as an alerting mechanism or simple monitoring device for your KPIs.”Jacques gave a great example of an inventory manager who took part of an afternoon off to go golfing before winter finally hit, and while on the front nine holes, his phone vibrated. His scorecard was alerting him that the inventory levels for one of the products was below some threshold that he had set.  From his phone, he had set up three options within Oracle Scorecard and Strategy Management (OSSM) for this type of situation:  1. Contact the warehouse manager directly by phone and work it out (standard phone function)  2. Tap/hold the KPI and add an annotation to the KPI in OSSM using the dictation capabilities of the phone and deal with it more fully when he gets back to the office  3. Tap/hold the KPI and invoke a business process from OSSM to transfer product from another warehouse with higher stock levels to the one that needs it  Being on a phone should still give you options to quickly deal with situations as needed, but mobile phones are not designed for nor should try to replicate the full desktop experience. We covered other interesting subjects in the interview, including how Oracle is keeping pace with mobile innovation and new devices such as Google Glasses, Galaxy Gear, Pebble Watches and more, and how Oracle is handling mobile security– which is great news for our mobile workforce.

  • Performing an upgrade from TFS 2008 to TFS 2010

    - by Enrique Lima
    I recently had to go through the process of migrating a TFS 2008 SP1 to a TFS 2010 environment. I will go into the details of the tasks that I went through, but first I want to explain why I define it as a migration and not an upgrade. When this environment was setup, based on support and limitations for TFS 2008, we used a 32 bit platform for the TFS Application Tier and Build Servers.  The Data Tier, since we were installing SP1 for TFS 2008, was done as a 64 bit installation.  We knew at that point that TFS 2010 was in the picture so that served as further motivation to make that a 64bit install of SQL Server.  The SQL Server at that point was a single instance (Default) installation too.  We had a pretty good strategy in place for backups of the databases supporting the environment (and this made the migration so much smoother), so we were pretty familiar with the databases and the purpose they serve. I am sure many of you that have gone through a TFS 2008 installation have encountered challenges and trials.  And likely even more so if you, like me, needed to configure your deployment for SSL.  So, frankly I was a little concerned about the process of migrating.  They say practice makes perfect, and this environment I worked on is in some way my brain child, so I was not ready nor willing for this to be a failure or something that would impact my client’s work. Prior to going through the migration process, we did the install of the environment.  The Data Tier was the same, with a new Named instance in place to host the 2010 install.  The Application Tier was in place too, and we did the DefaultCollection configuration to test and validate all components were in place as they should. Anyway, on to the tasks for the migration (thanks to Martin Hinselwood for his very thorough documentation): Close access to TFS 2008, you want to make sure all code is checked in and ready to go.  We stated a difference of 8 hours between code lock and the start of migration to give time for any unexpected delay.  How do we close access?  Stop IIS. Backup your databases.  Which ones? TfsActivityLogging TfsBuild TfsIntegration TfsVersionControl TfsWorkItemTracking TfsWorkItemTrackingAttachments Restore the databases to the new Named Instance (make sure you keep the same names) Now comes the fun part! The actual import/migration of the databases.  A couple of things happen here. The TfsIntegration database will be scanned, the other databases will be checked to validate they exist.  Those databases will go through a process of data being extracted and transferred to the TfsVersionControl database to then be renamed to Tfs_<Collection>. You will be using a tool called tfsconfig and the option import. This tool is located in the TFS 2010 installation path (C:\Program Files\Microsoft Team Foundation Server 2010\Tools),  the command to use is as follows:    tfsconfig import /sqlinstance:<instance> /collectionName:<name> /confirmed Where <instance> is going to be the SQL Server instance where you restored the databases to.  <name> is the name you will give the collection. And to explain /confirmed, well this means you have done a backup of the databases, why?  well remember you are going to merge the databases you restored when you execute the tfsconfig import command. The process will go through about 200 tasks, once it completes go to Team Foundation Server Administration Console and validate your imported databases and contents. We’ll keep this manageable, so the next post is about how to complete that implementation with the SSL configuration.

  • Slick2D, Nifty GUI listeners problem

    - by Patokun
    I'm trying to get Nifty GUI to work with Slick2D. So far everything is going great, except that I can't seem to figure out how to properly interact with the GUI. I'm trying the example in the nifty manual http://sourceforge.n....0.pdf/download but it doesn't seem to entirely work. The Element controller is being called for bind(...), init(...) and onStartScreen() as it should, as I can see their println output, but the next() method isn't being called when I click on the GUI element that I assigned the controller to, nor the screen controller as no output from println is shown. What's weird is, that the player is moving, so the mouse input is working. It's supposed to be called when I click the mouse button on it from the in the XML. Here is my code: My Element controller: public class ElementController implements Controller { private Element element; @Override public void bind(Nifty nifty, Screen screen, Element element, Properties parameter, Attributes controlDefinitionAttributes) { this.element = element; System.out.println("bind() called for element: " + element); } @Override public void init(Properties parameter, Attributes controlDefinitionAttributes) { System.out.println("init() called for element: " + element); } @Override public void onStartScreen() { System.out.println("onStartScreen() alled for element: " + element); } @Override public void onFocus(boolean getFocus) { System.out.println("onFocus() called for element: " + element + ", with: " + getFocus); } @Override public boolean inputEvent(NiftyInputEvent inputEvent) { return false; } public void next() { System.out.println("next() clicked for element: " + element); } } MyScreenController: class MyScreenController implements ScreenController { public void bind(Nifty nifty, Screen screen) {} public void onEndScreen() {} public void onStartScreen() {} public void next() { System.out.println("next() called from MyScreenController"); } } And my XML file: <?xml version="1.0" encoding="UTF-8"?> <nifty xmlns="http://nifty-gui.sourceforge.net/nifty-1.3.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://niftygui.sourceforge.net/nifty-1.3.xsd http://nifty-gui.sourceforge.net/nifty-1.3.xsd"> <screen id="start" controller="predaN00b.theThing.V0004.MyScreenController"> <layer childLayout="center" controller="predaN00b.theThing.V0004.ElementController"> <panel width="100px" height="100px" childLayout="vertical" backgroundColor="#ff0f"> <text font="aurulent-sans-16.fnt" color="#ffff" text="Hello World!"> <interact onClick="next()" /> </text> </panel> </layer> </screen> </nifty> My main class, in case it's needed: public class MainGameState extends BasicGame { public Nifty nifty; public MainGame() { super("Test"); } public void init(GameContainer container, StateBasedGame game) throws SlickException { nifty = new Nifty(new SlickRenderDevice(container), new NullSoundDevice(), new PlainSlickInputSystem(), new AccurateTimeProvider()); nifty.addXml("/xml/MainState.xml"); nifty.gotoScreen("start"); } public void update(GameContainer container, StateBasedGame game, int delta) throws SlickException { nifty.update(); } public void render(GameContainer container, StateBasedGame game, Graphics graphics) throws SlickException { nifty.render(false); } public static void main(String[] args) throws SlickException { AppGameContainer app = new AppGameContainer(new MainGame()); app.setAlwaysRender(true); app.setDisplayMode( 1260 , 720, false); //window size app.start(); } }

  • #iPad at One Week: A Great Device Made with a Heavy Hand

    - by andrewbrust
    I have now had my iPad for a little over a week. In that time, Apple introduced the world to its iPhone OS 4 (and the SDK agreement’s draconian new section 3.3.1), HP introduced is Slate, and Microsoft got ready to launch Visual Studio 2010 and .NET 4.0. And through it all I have used my iPad. I've used it for email, calendar, controlling my Sonos, and writing an essay. I've used it for getting on TripIt and Twitter, and surfing the Web. I've used it for online banking, and online ordering and delivery of food. And the verdict? Honestly? I think it's a great device and I thoroughly enjoy using it. The screen is bright and vibrant. I am surprisingly fast and accurate when I type on it. The touch screen's responsiveness is nearly flawless. The software, including a number of third party applications, include pleasing animations and use of color that make it fun to get work done. And speaking of work, the Exchange integration is, dare I say it, robust. Not as full-featured as on a PC or Windows Mobile device, but still offering core functionality and, so far at least, without bugs. The UI is intuitive, not just to me, but also to my 5 1/2 year old, and also to my nearly-3-year-old son. They picked it up and, with just just a few pointers from me, they almost immediately knew what to do, whether they were looking at photos (and swiping/flicking along as they did so), using a drawing program, playing a game, or watching YouTube videos. The younger of the two of them even tried to get up on a chair and grab the thing today. He dropped it, from about 4 feet off the ground. And it's still fine. (Meanwhile, I'll be keeping it on a higher shelf.) I cannot fully describe yet what makes this form factor and this product so appealing. Maybe it's that it's an always-on device. Maybe it's just being able to hold such a nice, relatively large display so close. Maybe it's the design sensibility, that seems to pervade throughout the app ecosystem. Or maybe it's that one's fingers, and not pens or mice, are the software's preferred input device. Whatever the attraction, it's strong. And no matter how much I tend to root for Microsoft and against Apple, Cupertino has, in my mind, scored big, Can Microsoft compete? Yes, but not with the Windows 7 standard UI (nor with individual OEMs’ own UIs on top). I hope Microsoft builds a variant of the Windows Phone 7 specifically for tablet devices. And I hope they make it clear that all developers, and programming languages, are welcome to the platform. Once that’s established, the OEMs have to build great hardware with fast, responsive touch screens, under Microsoft's watchful eye. That may be the hardest part of getting this right. No matter what, Microsoft's got a fight on its hands. I don't know if it can count on winning that fight, either. But Silverlight and Live Tiles could certainly help. And so can treating developers like adults.  Apple seems intent on treating their devs like kids, and then giving the kids a curfew.  For that, dev-friendly Microsoft may one day give thanks.

  • jqGrid - customizing the multi-select option (restrict single selection and adding custom events)

    - by Renso
    Goal: Using the jgGrid to enable a selection of a checkbox for row selection - which is easy to set in the jqGrid - but also only allowing a single row to be selectable at a time while adding events based on whether the row was selected or de-selected. Environment: jQuery 1.4.4 jqGrid 3.4.4a Issue: The jqGrid does not support the option to restrict the multi-select to only allow for a single selection. You may ask, why bother with the multi-select checkbox function if you only want to allow for the selection of a single row? Good question, as an example, you want to reserve the selection of a row to trigger another kind of event and use the checkbox multi-select to handle a different kind of event; in other words, when I select the row I want something entirely different to happen than when I select to check off the checkbox for that row. Also the setSelection method of the jqGrid is a toggle and has no support for determining whether the checkbox has already been selected or not, So it will simply act as a switch - which it is designed to do - but with no way out of the box to only check off the box (as in not to de-select) rather than act like a switch. Furthermore, the getGridParam('selrow') does not indicate if the row was selected or de-selected, which seems a bit strange and is the main reason for this blog post. Solution: How this will act: When you check off a multi-select checkbox in the gird, and then commence to select another row by checking off that row's multi-select checkbox - I'm not talking there about clicking on the row but using the grid's multi-select checkbox - it will de-select the previous selection so that you are always left with only a single selection. Furthermore, once you select or de-select a multi-select checkbox, fire off an event that will be determined by whether or not the row was selected or de-selected, not just merely clicked on. So if I de-select the row do one thing but when selecting it do another. Implementation (this of course is only a partial code snippet):             multiselect: true,             multiboxonly: true,             onSelectRow: function (rowId) {                 var gridSelRow = $(item).getGridParam('selrow');                 var s;                 s = $(item).getGridParam('selarrrow');                 if (!s || !s[0]) {                     $(item).resetSelection();                     $('#productLineDetails').fadeOut();                     lastsel = null;                     return;                 }                 var selected = $.inArray(rowId, s) != -1;                 if (selected) {                     $('#productLineDetails').show();                 }                 else {                     $('#productLineDetails').fadeOut();                 }                 if (rowId && rowId !== lastsel && selected) {                     $(item).GridToForm(gridSelRow, '#productLineDetails');                     if (lastsel) $(item).setSelection(lastsel, false);                 }                 lastsel = rowId;             }, In the example code above: The "item" property is the id of the jqGrid. The following to settings ensure that the jqGrid will add the new column to select rows with a checkbox and also the not allow for the selection by clicking on the row but to force the user to have to click on the multi-select checkbox to select the row: multiselect: true, multiboxonly: true, Unfortunately the var gridSelRow = $(item).getGridParam('selrow') function will only return the row the user clicked on or rather that the row's checkbox was clicked on and NOT whether or not it was selected nor de-selected, but it retrieves the row id, which is what we will need. The following piece get's all rows that have been selected so far, as in have a checked off multi-select checkbox: var s; s = $(item).getGridParam('selarrrow'); Now determine if the checkbox the user just clicked on was selected or de-selected: var selected = $.inArray(rowId, s) != -1; If it was selected then show a container "#productLineDetails", if not hide that container away. The following instruction populates a form with the grid data using the built-in GridToForm method (just mentioned here as an example) ONLY if the row has been selected and NOT de-selected but more importantly to de-select any other multi-select checkbox that may have been selected: if (rowId && rowId !== lastsel && selected) {                     $(item).GridToForm(gridSelRow, '#productLineDetails');                     if (lastsel) $(item).setSelection(lastsel, false); }

    - by SlyrNemesis
    Linux newbie here, anyway so here is the problem, I run Ubuntu 10.10 and I have a Sitecom 300N x2 Wireless Network dongle with chipset 8192SU, I used ndiswrapper to install my Windows Wireless driver because Sitecom doesn't have a linux driver, it says hardware present but it doesn't find any Wireless networks, nor does it connect to one.

  • App Stores&ndash;In All Things, Its Quality Over Quantity

    - by D'Arcy Lussier
    Everybody has an opinion about Windows 8. People love it, people hate it, people are meh about it, people are apparently buying it from Microsoft stores in NYC as if it was water before a natural disaster…if there’s one thing that Microsoft product launches do well, its the ability to bring out strong emotional responses. Over at eweek.com, Don Reisinger wrote about 5 good and bad things about Windows 8. Yes, another opinion piece on WIndows 8. I figured since this one had good and bad it might be worthwhile to read. I then came across #10 on his list, and figured “What the hell…might as well post a bit of a rant on Windows 8 myself!” Here’s #10: 10. Bad: Too few apps Unfortunately, Microsoft wasn’t able to get too many developers to start producing applications for its Windows 8 Store. Microsoft hasn’t yet released official numbers, but some have said that the marketplace has less than 8,000 programs. Considering Apple’s App Store has 100 times that, it’s about time Microsoft starts leaning on developers to get more programs into its store. Believe me, Microsoft *has* been leaning on developers to get apps into the store. I’ve been asked at least 5 or 6 times from 5 or 6 different friends at Microsoft about whether I was going to write a Windows 8 app. I think Microsoft felt they had to try and address the number of apps available in their marketplace, since some people (like Don) would draw comparisons to the number of apps in the Apple marketplace. I feel for Microsoft in this, since the number of apps in a marketplace are an empty stat. Quality of Quantity I have an iPad that my family (wife, 10yo daughter, 3yo daughter) use. We all have our own apps installed on it. In addition, my wife has an iPhone 4S that she also installs apps on. As someone who gets asked by his kids often whether they can buy/download an app, the vast majority of the vast catalogue of iOS marketplace apps are crap! Do you realize how many “free” games are out there, only to really be not-free because you have to purchase in-game content to make the game actually playable? And how about searching – with such a vast array of apps and such high numbers of craptastic ones, trying to find something is incredibly difficult and can be frustrating. I would rather see that Microsoft has 8000 high quality apps in their store at launch, instead of 800000 that were mostly junk. Too Few Apps?! And seriously, 8000 is not a small number. How many iOS apps have I actually bought between the iPad and iPhone? I’ll be generous and say 30…heck, let’s round it up to 40. It’s not like I have 10,000 apps installed on my iPad, nor will that ever happen! So if people have, at the *launch* of a new platform ecosystem, EIGHT THOUSAND apps to choose from, I don’t see that as a fail at all! It should be noted that most of the most common apps (Netflix, Skype, etc.) are available for Windows 8 at launch – I guess I’ll have to wait a few weeks for My Pony Ranch and all its clones to start showing up; pity. Let’s Check Back in a Year So look, let’s check back in a year’s time and see what the app store looks like. My hope is that Microsoft doesn’t continue to push quantity over quality. Even knowing the optics that # of apps in the store carries and the pressure to catch Apple and Android marketplaces, I hope Microsoft avoids the scenario where there’s a good percentage of apps in the Windows Store that are utter rubbish and finding the gems will be cumbersome. But if that happens, we can thank guys like Dan who raised the false issue of app count at the launch for it.

  • Ubuntu 13.04 installation issues: unable to handle kernel paging request error

    - by user173944
    I wish I could say that I’ve done more for the Linux community as of recent but I am very VERY new to all of this and I feel very much in over my head. I figured I would install Ubuntu. on my computer and then I would learn and contribute to the community simultaneously. I will try to be as detailed as I can, please ask questions if you need clarification. I installed Ubuntu. 13.04 (64-bit) on my dell Inspiron 1501. This has an AMD Turion 64-bit TL-56 1.8 Ghz mobile processor. It is a dual core. It has an ATI Radeon Xpress 1150 chipset in it as well. As of right now I only have a total of 2Ghz ram, however I was planning on upgrading that in the near future so I opted for the 64-bit Ubuntu. 13.04. I first tried the live CD and everything seemed to be functioning correctly other than the wireless (but that's not the issue at hand, there are plenty of guides on the internet on how to get that functioning). The internet worked just fine when it was plugged in so no issues there. However, once I went from that to installing 13.04 (just 13.04, no dual partitioning... I want this computer to run strictly Ubuntu.) it did not work. It took me into a shell that I could not type anything into. In this shell it said Bug: unable to handle kernel paging and then it called a bunch of traces and froze up. I had to hard reset the laptop. I tried the boot-repair program multiple times with many different settings and typically after starting up the laptop would say something along the lines of recursive errors. will attempt to fix and then it would attempt to fix a couple of things, and then the computer would freeze up after the text said end trace... so I had to hard reset it again. I'm not an impatient person either, when I say it would freeze up it would be for a period of at least 15 minutes each time before I decided to hard reset. I attempted to install 12.10 on it instead and I got the same exact message, and when I ran boot-repair it did the same exact thing as before. I am currently in the process of running memtest64+ on the computer's memory, though I really don't believe that, nor any of the hardware is at fault due to the fact that it was still running windows vista perfectly when I had decided to switch over to Ubuntu. so far the memtest has came back just fine without any errors, but I’ve only been running it for approximately an hour. So this is the situation I’m in. I did notice when I was using the live disk that the video driver needed updated so I performed that, though I’m fairly certain that has nothing to do with this. I have also attempted (though I’m not certain that my attempt was successful in accomplishing what I had planned) to manually edit the grub settings by making acpi=0 along top of adding nomodeset to the boot commands. Like I said, I’m not sure I did that correctly though, but I’m fairly certain I did. If anyone needs any more information I will be more than happy to provide it, I will post back once I get the full results of the memtest. I very much appreciate any ideas anyone else has, I’ve been at this for a few days to no avail... thank you

  • SQL SERVER – Puzzle #1 – Querying Pattern Ranges and Wild Cards

    - by Pinal Dave
    Note: Read at the end of the blog post how you can get five Joes 2 Pros Book #1 and a surprise gift. I have been blogging for almost 7 years and every other day I receive questions about Querying Pattern Ranges. The most common way to solve the problem is to use Wild Cards. However, not everyone knows how to use wild card properly. SQL Queries 2012 Joes 2 Pros Volume 1 – The SQL Queries 2012 Hands-On Tutorial for Beginners Book On Amazon | Book On Flipkart Learn SQL Server get all the five parts combo kit Kit on Amazon | Kit on Flipkart Many people know wildcards are great for finding patterns in character data. There are also some special sequences with wildcards that can give you even more power. This series from SQL Queries 2012 Joes 2 Pros® Volume 1 will show you some of these cool tricks. All supporting files are available with a free download from the www.Joes2Pros.com web site. This example is from the SQL 2012 series Volume 1 in the file SQLQueries2012Vol1Chapter2.2Setup.sql. If you need help setting up then look in the “Free Videos” section on Joes2Pros under “Getting Started” called “How to install your labs” Querying Pattern Ranges The % wildcard character represents any number of characters of any length. Let’s find all first names that end in the letter ‘A’. By using the percentage ‘%’ sign with the letter ‘A’, we achieve this goal using the code sample below: SELECT * FROM Employee WHERE FirstName LIKE '%A' To find all FirstName values beginning with the letters ‘A’ or ‘B’ we can use two predicates in our WHERE clause, by separating them with the OR statement. Finding names beginning with an ‘A’ or ‘B’ is easy and this works fine until we want a larger range of letters as in the example below for ‘A’ thru ‘K’: SELECT * FROM Employee WHERE FirstName LIKE 'A%' OR FirstName LIKE 'B%' OR FirstName LIKE 'C%' OR FirstName LIKE 'D%' OR FirstName LIKE 'E%' OR FirstName LIKE 'F%' OR FirstName LIKE 'G%' OR FirstName LIKE 'H%' OR FirstName LIKE 'I%' OR FirstName LIKE 'J%' OR FirstName LIKE 'K%' The previous query does find FirstName values beginning with the letters ‘A’ thru ‘K’. However, when a query requires a large range of letters, the LIKE operator has an even better option. Since the first letter of the FirstName field can be ‘A’, ‘B’, ‘C’, ‘D’, ‘E’, ‘F’, ‘G’, ‘H’, ‘I’, ‘J’ or ‘K’, simply list all these choices inside a set of square brackets followed by the ‘%’ wildcard, as in the example below: SELECT * FROM Employee WHERE FirstName LIKE '[ABCDEFGHIJK]%' A more elegant example of this technique recognizes that all these letters are in a continuous range, so we really only need to list the first and last letter of the range inside the square brackets, followed by the ‘%’ wildcard allowing for any number of characters after the first letter in the range. Note: A predicate that uses a range will not work with the ‘=’ operator (equals sign). It will neither raise an error, nor produce a result set. --Bad query (will not error or return any records) SELECT * FROM Employee WHERE FirstName = '[A-K]%' Question: You want to find all first names that start with the letters A-M in your Customer table and end with the letter Z. Which SQL code would you use? a. SELECT * FROM Customer WHERE FirstName LIKE 'm%z' b. SELECT * FROM Customer WHERE FirstName LIKE 'a-m%z' c. SELECT * FROM Customer WHERE FirstName LIKE 'a-m%z' d. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]%z' e. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]z%' f. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]%z' g. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]z%' Contest Leave a valid answer before June 18, 2013 in the comment section. 5 winners will be selected from all the valid answers and will receive Joes 2 Pros Book #1. 1 Lucky person will get a surprise gift from Joes 2 Pros. The contest is open for all the countries where Amazon ships the book (USA, UK, Canada, India and many others). Special Note: Read all the options before you provide valid answer as there is a small trick hidden in answers.

  • Resolve SRs Faster Using RDA - Find the Right Profile

    - by Daniel Mortimer
    Introduction Remote Diagnostic Agent (RDA) is an excellent command-line data collection tool that can aid troubleshooting / problem solving. The tool covers the majority of Oracle's vast product range, and its data collection capability is comprehensive. RDA collects data about the operating system and environment, including environment variable, kernel settings network o/s performance o/s patches and much more the Oracle Products installed, including patches logs and debug metrics configuration and much more In effect, RDA can obtain a snapshot of an Oracle Product and its environment. Oracle Support encourages the use of RDA because it greatly reduces service request resolution time by minimizing the number of requests from Oracle Support for more information. RDA is designed to be as unobtrusive as possible; it does not modify systems in any way. It collects useful data for Oracle Support only and a security filter is provided if required. Find and Use the Right RDA Profile One problem of any tool / utility, which covers a large range of products, is knowing how to target it against only the products you wish to troubleshoot. RDA does not have a GUI. Nor does RDA have an intelligent mechanism for detecting and automatically collecting data only for those Oracle products installed. Instead, you have to tell RDA what to do. There is a mind boggling large number of RDA data collection modules which you can configure RDA to use. It is easier, however, to setup RDA to use a "Profile". A profile consists of a list of data collection modules and predefined settings. As such profiles can be used to diagnose a problem with a particular product or combination of products. How to run RDA with a profile? ( <rda> represents the command you selected to run RDA (for example, rda.pl, rda.cmd, rda.sh, and perl rda.pl).) 1. Use the embedded spreadsheet to find the RDA profile which is appropriate for your problem / chosen Oracle Fusion Middleware products. 2. Use the following command to perform the setup <rda> -S -p <profile_name>  3. Run the data collection <rda> Run the data collection. If you want to perform setup and run in one go, then use a command such as the following: <rda> -vnSCRP -p <profile name> For more information, refer to: Remote Diagnostic Agent (RDA) 4 - Profile Manual Pages [ID 391983.1] Additional Hints / Tips: 1. Be careful! Profile names are case sensitive.2. When profiles are not used, RDA considers all existing modules by default. For example, if you have downloaded RDA for the first time and run the command <rda> -S you will see prompts for every RDA collection module many of which will be of no interest to you. Also, you may, in your haste to work through all the questions, forget to say "Yes" to the collection of data that is pertinent to your particular problem or product. Profiles avoid such tedium and help ensure the right data is collected at the first time of asking.

  • Planning development when academic research is involved

    - by Another Anonymous User
    Dear fellow programmers, how do you do "software planning" when academic research is involved? And, on a side note, how do you convince your boss that writing software is not like building a house and it's more like writing a novel? The gory details are below. I am in charge of a small dev team working in a research lab. We started developing a software with the purpose of going public one day (i.e. sell and make money off that). Such software depends on, amongst other things, at least two independent research lines: that is, there are at least two Ph.D. candidates that will, hopefully, one day come out with a working implementation of what we need. The main software depends also on other, more concrete resources that we as developers can take care of: graphics rendering, soft bodies deformation, etc. My boss asked me to write the specifications, requirements AND a bloody GANTT chart of the entire project. Faced with the fact that I don't have a clue about the research part, and that such research is fundamental for the software, he said "make assumptions." For the clarity of the argument, he is a professor whose Ph.D. students should come up with the research we need. And he comes from a strictly engineering background: plan everything first, write down specifications and only then write down code that "it's the last part". What I am doing now: I broke down the product in features; each 'feature' is, de facto, a separate product; Each feature is built on top of the previous one; Once a feature (A) has a working prototype the team can start working on the next feature (B), while QA for is being done for A (if money allows, more people can be brought in, etc.); Features that depend on research will come last: by then, hopefully, the research part will be completed (when is still a big question) ; Also, I set the team to use SCRUM for the development of 'version 1.0', due in a few months. This deadline could be set based on reasonable assumptions: we listed all required features, we counted our availability, and we gave a reasonable estimate. So my questions, again, are: How do I make my boss happy while at the same time get something out the door? How do I write specifications for something we -the developers- have no clue whether it's possible to do or not? (We still haven't decided which libraries to use for some tasks; we'll do so when we'll need to) How do I get the requirements for that, given that there are yet no clients nor investors, just lots of interests and promises? How do I get peace in the world? I am sure at least one of my questions will be answered :) ps: I am writing this anonymously since a potential investor might backfire if this is discovered. Hope you'll understand. However I must say I do not like this mentality of 'hiding the truth': this program will likely benefit many, and not being able to talk openly about this (with my name and my reputation attached) feels like censorship. But alas, I care more about your suggestions now.
