• Java ME SDK 3.0.5 Integrated with NetBeans 7.1.1

  - by SungmoonCho

  NetBeans 7.1.1 now integrates Java ME SDK 3.0.5, so you do not have to download them separately. Java ME SDK was packaged in NetBeans Mobility Pack, a mobile application development toolkit for NetBeans. Therefore, Java ME SDK is no longer a separate menu on NetBeans. For those who have not downloaded Java ME SDK yet, please simply visit NetBeans website and download the latest version. For those who already have Java ME SDK integrated with NetBeans 7.1 or earlier, and want to update NetBeans IDE to 7.1.1, don't worry. They can co-exist. To use NetBeans plug-ins such as Device Selector, profiler, and Internationalization Resource Manager, you have to install "Java ME SDK Tools" from NetBeans. Here is how. 1.  Go to "Tools - Plug-ins" from NetBeans menu. You can find all the plug-ins you can install into NetBeans. Locate "Java ME SDK Tools" from the list. 2. Follow the instruction to install Java ME SDK Plug-ins. 3. Once completed, you will see new menu options. For example, you can find Device Selector under Tools - Java ME. (If you used old version of Java ME, you will notice that there is not 'Java ME' menu any more. This is because all the sub-menus were integrated into appropriate places in NetBeans.) There is one thing to keep in mind; Since NetBeans 7.1.1 already includes Java ME SDK 3.0.5 and Java ME SDK 3.0.5 plug-ins must be installed through NetBeans plug-in menu, you should not download Java ME SDK 3.0.5 separately and try to integrate it with NetBeans. This may cause issues.

• SSISDB Analysis Script on Gist

  - by Davide Mauri

  I've created two simple, yet very useful, script to extract some useful data to quickly monitor SSIS packages execution in SQL Server 2012 and after.get-ssis-execution-status  get-ssis-data-pumped-rows  I've started to use gist since it comes very handy, for this "quick'n'dirty" scripts and snippets, and you can find the above scripts and others (hopefully the number will increase over time...I plan to use gist to store all the code snippet I used to store in a dedicated folder on my machine) there.Now, back to the aforementioned scripts. The first one ("get-ssis-execution-status") returns a list of all executed and executing packages along with latest successful and running executions (so that on can have an idea of the expected run time)error messageswarning messages related to duplicate rows found in lookupsthe second one ("get-ssis-data-pumped-rows") returns information on DataFlows status. Here there's something interesting, IMHO. Nothing exceptional, let it be clear, but nonetheless useful: the script extract information on destinations and row sent to destinations right from the messages produced by the DataFlow component. This helps to quickly understand how many rows as been sent and where...without having to increase the logging level.Enjoy! PSI haven't tested it with SQL Server 2014, but AFAIK they should work without problems. Of course any feedback on this is welcome.

• Laptop Charger Not Recognised Properly on Samsung NP900X3F

  - by user193732

  Firstly thanks for your time. Secondly, having an issue with my power charger on my Samsung Series 9 NP900X3F. When I boot into Ubuntu with the charger plugged in it recognises it as charging. When I unplug the charger after this it is still says it is charging. If I suspend in Ubuntu then plug/unplug during this suspended state it recognises it, but not during normal running. If I knew a little more I'm sure I could grab logs and find out what the difference between wake on suspend and normal running is, but alas I need help! I also am having issues with my keyboard backlight via the fn keys, but that I care about far less. Thank you very much. Linux mikey-900X3F 3.12.0-031200rc1-generic #201309161735 SMP Mon Sep 16 21:38:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux (I upgraded my kernel version to remove heinous horizontal artefacts I was getting) Happy to list more info about my system, ima bit of a noob. I did try searching however I can't find any questions at all about my system or related models with the same issue.

• Ubuntu won't suspend anymore, but it did upon install.

  - by Bruce Connor

  I fresh installed Ubuntu 10.10 back when it came out, and my laptop was suspending fine. All of a sudden, I can't get my laptop to suspend anymore. It's an HP Pavilion dv2-1110, but I don't think it's a hardware issue, here's why: It suspended fine upon first install. I haven't installed any new kernels since then, but I have installed tons of packages, so it's probably a package. The suspend and hibernate options disappeared from the shutdown menu. If I press my keyboard's suspend button (or if I close the lid) I get the following message: If I try the command pmi action suspend, I get the error message: Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files. If I try the command echo -n mem > sudo /sys/power/state I get absolutely no output and no visible effect. What might be causing this behavior? I thought a list of installed packages might be useful, but it's huge and I don't know how to post it here in collapse/expand mode or something. EDIT:Just in case someone asks, none of the installed packages are kdm or anything like that (which would justify the lack of options in gnome's shutdown menu).

• Snake Game Help

  - by MuhammadA

  I am making a snake game and learning XNA at the same time. I have 3 classes : Game.cs, Snake.cs and Apple.cs My problem is more of a conceptual problem, I want to know which class is really responsible for ... detecting collision of snake head on apple/itself/wall? which class should increase the snakes speed, size? It seems to me that however much I try and put the snake stuff into snake.cs that game.cs has to know a lot about the snake, like : -- I want to increase the score depending on size of snake, the score variable is inside game.cs, which means now I have to ask the snake its size on every hit of the apple... seems a bit unclean all this highly coupled code. or -- I DO NOT want to place the apple under the snake... now the apple suddenly has to know about all the snake parts, my head hurts when I think of that. Maybe there should be some sort of AppleLayer.cs class that should know about the snake... Whats the best approach in such a simple scenario? Any tips welcome.

• How do I convince my boss that it's OK to use an application to access an outside website?

  - by Cyberherbalist

  That is, if you agree that it's OK. We have a need to maintain an accurate internal record of bank routing numbers, and my boss wants me to set up a process where once a week someone goes to the Federal Reserve's website, clicks on the link to get the list of routing numbers (or the link giving the updates since a particular date), and then manually uploads the resultant text file to an application that will make the update to our data. I told him that a manual process was not at all necessary, and that I could write a routine that would access the FED's routing numbers in the application that keeps our data updated, and put it on whatever schedule was appropriate. But he is greatly opposed to doing this, and calls it "hacking the Federal Reserve website." I think he's afraid that the FED is going to get after us. I showed him the FED's robot.txt file, and the only thing it forbids is an automated indexing of pages with extension .cf*: User-agent: * # applies to all robots Disallow: CF # disallow indexing of all CF* directories and pages This says nothing about accessing the same data automatically that you could access manually. Anyone have a good counterargument to the idea that we'd be "hacking" the FED?

• Data structure for bubble shooter game

  - by SundayMonday

  I'm starting to make a bubble shooter game for a mobile OS. Assume this is just the basic "three or more same-color bubbles that touch pop" and all bubbles that are separated from their group fall/pop. What data structures are common for storing the bubbles? I've considered using an undirected, connected graph where each node is a bubble. This seems like it could help answer the question "which bubbles (if any) should fall now?" after some arbitrary bubbles are popped and corresponding nodes are removed from the graph. I think the answer is all bubbles that were just disconnected from the graph should fall. However the graph approach might be overkill so I'm not sure. Another consideration for the data structure is collision detection. Perhaps being able to grab a list of neighboring bubbles in constant time for a particular "bubble slot" is useful. So the collision detection would be something like "moving bubble is closest to slot ij, neighbors of slot ij are bubbles a,b,c, moving bubble is sufficiently close to bubble b hence moving bubble should come to rest in slot ij". A game like this could be probably be made with a relatively crude grid structure as the primary data structure. However it seems like answering "which bubbles (if any) should fall now?" would be trickier with this data structure.

• Trying to install Canon LBP7750Cdn driver on Ubuntu 12.04

  - by Gideon

  I'n new to Ubuntu/Linux and had significant difficulties while attempting to configure my printer to work. The automatic driver pairing wizard which Ubuntu uses to identify and install the appropriate drivers did not find my printer's driver. I managed to get it to print when I manually select the generic configuration and checked the PCL6 configuration. However, the printer driver wizard does provide a list of Canon printers and actually do specify my printer as LBP7750C (minus the "dn" at the end, I'm assuming its because duplex ability and networking is not present on all the models - I'm not sure if this could be the source of the problem), but in selecting this option and trying to print I receive this message: Idle - /usr/lib/cups/filter/foomatic-rip failed I searched for this similar problem which other users might have encountered, but while there where plenty of such cases, they all had different resolutions and were all related to HP printers. Canon actually do provide a driver for my printer, but it comes with no installation instructions unless you consider yourself an experienced CUPS guru. Seriously. If anyone can help me solve this foomatic-rip failed problem I'd be really grateful - and I'm sure many other folks too. [BTW, can't Canonical fix this type of thing for the next Ubuntu release? - I't seems like a small problem but it causes many problems and countles hours of production time loss.] Thanks in advance.

• MapReduce

  - by kaleidoscope

  MapReduce is a programming model and an associated implementation for processing and generating large data sets. Users specify a map function that processes a key/value pair to generate a set of  intermediate key/value pairs, and a reduce function that merges all intermediate values associated with the same intermediate key. Many real world tasks are expressible in this model, as shown in the paper. Programs written in this functional style are automatically parallelized and executed on a large cluster of commodity machines. The run-time system takes care of the details of partitioning the input data,  scheduling the program's execution across a set of machines, handling machine failures, and managing the required inter-machine communication. This allows programmers without any experience with parallel and distributed systems to easily utilize the resources of a large distributed system. Example: A process to count the appearances of each different word in a set of documents void map(String name, String document):   // name: document name   // document: document contents   for each word w in document:     EmitIntermediate(w, 1); void reduce(String word, Iterator partialCounts):   // word: a word   // partialCounts: a list of aggregated partial counts   int result = 0;   for each pc in partialCounts:     result += ParseInt(pc);   Emit(result); Here, each document is split in words, and each word is counted initially with a "1" value by the Map function, using the word as the result key. The framework puts together all the pairs with the same key and feeds them to the same call to Reduce, thus this function just needs to sum all of its input values to find the total appearances of that word.   Sarang, K

• What should happen at the start of a software project startup?

  - by Willem

  A quick introduction My college semesters include a 8 week project working for an actual company with a software need in order to get some much needed practical experience. I have just started such a project with 5 other students. We're required to spend roughly 40 hours a week per student on this project. We're working with SCRUM as the software development method, this was assigned by our teachers. The question Day one of the project just ended which has created some questions for me as to how to start a project in the 'real world'. Our first day included working on a project planning document (not sure what the English term is), creating a appointment with the company for an introduction and the opportunity to start specifying the requirements and setting up some standards for the behavior within the group. However these items didn't take that long to finish. We've made some concrete plans for tomorrow and the day after we'll meet the company. This still leaves several hours of 'work-time' unspent. Is it usual not being able to fill every hour of a day for work at the start of a project or are we simply too inexperienced to see what work needs to be done at this stage of a project, or are we, perhaps, going through the above list too fast? How does this work in the 'real world'? Do you spend your time wondering 'what should I do now', or do you have a clear view of what you're supposed to do at that moment?

• Book Review&ndash;Getting Started With OAuth 2.0

  - by Lori Lalonde

  Getting Started With OAuth 2.0, by Ryan Boyd, provides an introduction to the latest version of the OAuth protocol. The author starts off by exploring the origins of OAuth, along with its importance, and why developers should care about it. The bulk of this book involves a discussion of the various authorization flows that developers will need to consider when developing applications that will incorporate OAuth to manage user access and authorization. The author explains in detail which flow is appropriate to use based on the application being developed, as well as how to implement each type with step-by-step examples. Note that the examples in the book are focused on the Google and Facebook APIs. Personally, I would have liked to see some examples with the Twitter API as well. In addition to that, the author also discusses security considerations, error handling (what is returned if the access request fails), and access tokens (when are access tokens refreshed, and how access can be revoked). This book provides a good starting point for those developers looking to understand what OAuth is and how they can leverage it within their own applications. The book wraps up with a list of tools and libraries that are available to further assist the developer in exploring the APIs supporting the OAuth specification. I highly recommend this book as a must-read for developers at all levels that have not yet been exposed to OAuth. The eBook format of this book was provided free through O'Reilly's Blogger Review program. This book can be purchased from the O'Reilly book store at: : http://shop.oreilly.com/product/0636920021810.do

• Copying photos from camera stalls - how to track down issue?

  - by Hamish Downer

  When I copy files from my camera (connected via USB) to the SSD in my laptop a few files get copied and then the copy stalls. I'm not sure why, any ideas or things to investigate appreciated, or bug reports to go and look at. I have read this answer - the camera (Canon 40D in case that matters) mounts fine using gvfs. I can see the photos in Nautilus, or in the terminal (in /run/user/username/gvfs/... ) and I can copy a few photos, but not many. Using the terminal or Nautilus the process hangs until the camera goes to sleep. Digikam fails to copy any at all, as does Rapid Photo Downloader. Shotwell did manage it in the end, but that is very much a work around for me. I have disabled thumbnail generation by nautilus. Load average stays about 1 while this is happening, while CPU usage is half idle, half wait (and a little user/sys for other programs).

• How to show or direct a business analyst to do data modelling?

  - by AaronLS

  Our business analysts pushed hard to collect data through a spreadsheet. I am the programmer responsible for importing that data. Usually when they push hard for something like this, I never know how well it will work out until a few weeks later when I have time assigned to work on the task of programming the import of the data. I have tried to do as much as possible along the way, named ranges, data validations, etc. But I usually don't have time to take a detailed look at all the data and compare to the destination in the database to determine how well it matches up. A lot of times there will be maybe a little table of items that somehow I have to relate to something else in the database, but there are not natural or business keys present that would allow me to do so. Make the best of this, trying to write something that can compare strings and make a best guess at it and then go through the effort of creating interfaces for a user to match the imported data to the destination. I feel like if the business analyst was actually creating a data model, they would be forced to think about these relationships, and have an appreciation for the need of natural or business keys to be part of the spreadsheet for the purposes of smoothly importing the data. The closest they come to business analysis is a big flat list of fields, and that would be fine if it were like any other data dictionary and include data types+relationships, but it isn't. They are just a bunch of names. No indication of what type of data they might hold, and it is up to me to guess. When I have pushed for more detail, they say that it is just busy work. How can I explain the importance of data modelling? How can I tell them what it is and how to do it? It feels impossible, because they don't have an appreciation for its importance. They do however, usually have an interest in helping out in whatever way they can, it's just this in particular has never gotten a motivated response.

• C++ Iterator lifetime and detecting invalidation

  - by DK.

  Based on what's considered idiomatic in C++11: should an iterator into a custom container survive the container itself being destroyed? should it be possible to detect when an iterator becomes invalidated? are the above conditional on "debug builds" in practice? Details: I've recently been brushing up on my C++ and learning my way around C++11. As part of that, I've been writing an idiomatic wrapper around the uriparser library. Part of this is wrapping the linked list representation of parsed path components. I'm looking for advice on what's idiomatic for containers. One thing that worries me, coming most recently from garbage-collected languages, is ensuring that random objects don't just go disappearing on users if they make a mistake regarding lifetimes. To account for this, both the PathList container and its iterators keep a shared_ptr to the actual internal state object. This ensures that as long as anything pointing into that data exists, so does the data. However, looking at the STL (and lots of searching), it doesn't look like C++ containers guarantee this. I have this horrible suspicion that the expectation is to just let containers be destroyed, invalidating any iterators along with it. std::vector certainly seems to let iterators get invalidated and still (incorrectly) function. What I want to know is: what is expected from "good"/idiomatic C++11 code? Given the shiny new smart pointers, it seems kind of strange that STL allows you to easily blow your legs off by accidentally leaking an iterator. Is using shared_ptr to the backing data an unnecessary inefficiency, a good idea for debugging or something expected that STL just doesn't do? (I'm hoping that grounding this to "idiomatic C++11" avoids charges of subjectivity...)

• What does "fully supported" mean in context of Radeon Opensource Video Driver?

  - by stevecoh1

  UPDATE: This is not a request for support of my specific issue. Details of that issue are here: How to recover from bad upgrade to 13.04 (Unity very slow) . I have "solved" that issue, for the time being anyway, by loading alternative lighter weight desktops. This question was opened specifically to question the meaning of the documentation at https://help.ubuntu.com/community/RadeonDriver . END OF UPDATE There it is, in Black and White: https://help.ubuntu.com/community/RadeonDriver Fully Supported All these Radeon(HD) cards and derivatives have good 3D acceleration support. This is not an exhaustive list: ... RV610/RV630 Radeon HD 2400/2600/2700/4200/4225/4250 Yet in my case (the HD2400) this proves to be manifestly untrue, at least if "Fully Supported" means sufficient to run Unity in Ubuntu 13.04. It runs all the applications I can launch under Unity, but Unity itself is unbearably slow. It's quite striking really. Click on the "Dash" - go get a cup of coffee. Type a key in the Unity search box, wait five seconds for it to appear. Type Alt-tab and wait five seconds for the screen to finish painting. None of these issues appear outside of Unity components. As you all know, there are complaints about slow performance all over the Internet about Unity. Shouldn't this page somehow address this issue? Especially if "fully supported" doesn't mean sufficiently to run the default modern Ubuntu release. What does "fully supported" mean?

• Struggling with the Single Responsibility Principle

  - by AngryBird

  Consider this example: I have a website. It allows users to make posts (can be anything) and add tags that describe the post. In the code, I have two classes that represent the post and tags. Lets call these classes Post and Tag. Post takes care of creating posts, deleting posts, updating posts, etc. Tag takes care of creating tags, deleting tags, updating tags, etc. There is one operation that is missing. The linking of tags to posts. I am struggling with who should do this operation. It could fit equally well in either class. On one hand, the Post class could have a function that takes a Tag as a parameter, and then stores it in a list of tags. On the other hand, the Tag class could have a function that takes a Post as a parameter and links the Tag to the Post. The above is just an example of my problem. I am actually running into this with multiple classes that are all similar. It could fit equally well in both. Short of actually putting the functionality in both classes, what conventions or design styles exist to help me solve this problem. I am assuming there has to be something short of just picking one? Maybe putting it in both classes is the correct answer?

• Update to SQL Server Configuration Scripting Utility

  - by Bill Graziano

  Last spring I released a utility to script SQL Server configuration information on CodePlex.  I’ve been making small changes in this application as my needs have changed.  The application is a .NET 2.0 console application.  This utility serves two needs for me.  First it helps with disaster recovery.  All server level objects (logins, jobs, linked servers, audits) are scripted to a single file per object type.  This enables the scripts to be easily run against a DR server.  If these are checked into source control you can view the history of the script and find out what changed and when. The second goal is to capture what changed inside a database.  Objects inside a database (tables, stored procedures, views, etc.) are each scripted to their own file.  This makes it easier to track the changes to an object over time.  This does include permissions and role membership so you can capture security changes.  My assumption is that a database backup is the primary method of disaster recovery for databases so this utility is designed to capture changes to objects.  You can find the full list of changes from the original on the Downloads page on CodePlex.

• Web Hosting Checklist

  - by Chris

  Hello, I am a web developer that is starting to look into hosting his own website. I would like to showcase my programming skills (PHP, MySQl, C#, Wordpress). My knowledge of languages I am OK with but the actually hosting site is where my knowledge starts to get a little shaky. I know the basics (bandwidth, sub-domains, re-write rules) but I would love your input, to help me formulate a check list of certain web-hosting services that I should be on the look-out for. Also I was wondering if there were any reliable hosting providers who give you the option to host both c# code-behinds and PHP code. As I would like to have two versions of my site, one in C# and one in PHP the hope is that if I need to look for another job this website will help me show possible employers my server side knowledge. I hope this is enough info, I did some researching online but found a bunch of unless articles and I've always have had luck on the StackExchange sites. So hopefully you, can help me. Thanks alot.

• Setting up Cluster Configuration using an existing web server as a Primary Node?

  - by RapidWebs

  Thanks in advance for any help which is issued! I am having a slight issue, and need help with the decision making process when it comes to setting up my Cluster Configuration, consisting on a line of Ubuntu Servers (12.04). We currently have a Primary node, which resides in the US within a Datacenter, but we are going to be using this for all serious bandwidth and resource intensive websites, and through a configuration of Virtualmin + Webmin, will be setup as a sort of pseudo-cluster, using Virtualmins Cluster Modules. Anyways, on to the issue: We also have a business line setup locally, with three servers. here are their specs: Intel P4 2.4 ghz, 1GB Ram, 110 gb sata, Ubuntu 12.04* AMD 1.3 ghz, 512MB Ram, 20 GB IDE P3 Xeon 800mhz (dual physical processors), 1GB Ram, 3 * 25 GB Raid Configuration (one in use for host operating system). The first machine is currently IN USE and is serving virtual hosts off a sub-domain. My question is this: How can I integrate the Secondary node (which will be the Primary node per say, in this smaller configuration...) which is currently in use, into the cluster configuration w/ the other two servers for: Sharing Resources Redundancy (HA?) NFS /w the two Raid Disks without having the FORMAT the secondary node, and start fresh moving all my services in to a DRBD network drive or something similar, and than restoring all active virtualmin's Virtual hosts. the idea is that I want minimal downtime to people currently being served from server2.mywebsite.com, and from what I understand, all services need to be on a NFS so that they can be mounted on demand and accessed from the other machine taking over (i.e. Heartbeat + DRBD Config.) but my issue is that i already have all these services installed to their default directory structure: how can i most easily setup this NFS and HA system, move all my desires services to this new drive, and do it with minimal down time, and without breaking Virtualmin and everything else on my server? even just some pointers, a thread i could read, or a step by step check list or run down of commands i could issue to get started would be great! thanks!

• Use jQuery and ASP.NET to Build a News Ticker

  Many websites display a news ticker of one sort or another. A news ticker is a user interface element that displays a subset of a list of items, cycling through them one at a time after a set interval. For example, on Cisco's website there is a news ticker that shows the company's latest news items. Each news item is a one sentence link, such as "Desktop Virtualization Gathers Steam," or "Cisco Reports First Quarter Earnings." Clicking a headline whisks you to a page that shows the full story. Cisco's news ticker shows one headline at a time; every few seconds the currently displayed headline fades out and the next one appears. In total, Cisco has five different headlines - the ticker displays each of the five and then starts back from the beginning. This article is the first in a series that explores how to create your own news ticker widget using jQuery and ASP.NET. jQuery is a free, popular, open-source JavaScript library that simplifies many common client-side tasks, like event handling, DOM manipulation, and Ajax. This article kicks off the series and shows how to build a fairly simple news ticker whose contents can be specified statically in HTML markup or created dynamically from server-side code. Future installments will explore adding bells and whistles, such as: stopping the news ticker rotation when the mouse is hovered over it; adding controls to start, stop and pause the headlines; loading new headlines dynamically using Ajax; and packaging the JavaScript used by the ticker into a jQuery plugin. Read on to learn more! Read More >

• How do they keep track of the NPCs in Left 4 Dead?

  - by f20k

  How do they keep track of the NPC zombies in Left 4 Dead? I am talking about the NPCs that just walk into walls or wander around aimlessly. Even though the players cannot see them, they are there (say inside rooms or behind doors). Let's say there's about 10 or so zombies in a hallway and inside rooms. Does the game keep all of those zombies in a list and iterate through giving them commands? Do they just spawn when the user is within a certain radius or reached a special location? Say you placed the 4 units (controlled by players) on completely different places throughout the map. Let's assume you aren't being swarmed and then you have not killed any of these aimless NPCs. Would the game be keeping track of 10 x 4 = 40 zombies in total? Or is my understanding completely off? The reason I ask is if I were to implement something similar on a mobile device, keeping track of 40 or more NPCs might not be such a great idea.
