• Rotate a Video 90 degrees with VLC or Windows Live Movie Maker

  - by DigitalGeekery

  Have you ever captured video with your cell phone or camcorder only to discover when you play it back on your computer that the video is rotated 90 degrees? Or maybe you shot it that way on purpose because you preferred portrait style to a landscape view? Before you go straining your neck or flipping your monitor on it’s side to watch your video, we’ll show you a few easier methods. If you simply want to rotate the video while you watch it, we’ll show you how to accomplish that with VLC Media Player. If you want to convert the video so it is rotated permanently, we’ll show you how to do that with Windows Live Movie Maker and output your video as a WMV file. Rotate and Watch a Video in VLC Download, install, and run VLC Media Player. (See download link below)   Open your video file by going to Media  > Open File… and browsing for your file. Or, by just dragging and dropping your video onto the VLC player.   Choose Tools from the Menu bar and select Effects and Filters. On the Video Effects tab, tick the Transform checkbox and choose your degrees of rotation. The video is rotated counter-clockwise, so to rotate clockwise 90 degrees you’ll want to choose Rotate by 270 degrees.   Now you can enjoy your video the way it was intended to be viewed. Rotate and Convert the Video with Windows Live Movie Maker Starting with Windows 7, Windows Movie Maker no longer comes pre-installed with the OS. It’s now part of the Windows Live suite that is available as a separate, free download for Windows 7 and Vista. (Windows XP is not supported) You can find the link to our detailed instruction on how to install Windows Live at the end of the article. To add your video files to Windows Movie Maker, click on Add videos and photos on the Home tab, or drag and drop the video into the blank area on the right side of the application. Next, you’ll need to rotate the video. Staying on the Home tab, click on the Rotate right 90° or Rotate left 90°.   You’ll see your video is now oriented properly on the left.   To save and convert your video to WMV format, click the Movie Maker tab just to the left of the Home tab. Hover your cursor over Save movie, and then select your output settings. You also have the option to burn directly to DVD. Browse for a location to save it and rename the output file if you’d like. Click Save. You’ll be notified when the file is complete. Now you’ll have your video properly oriented in WMV file format.   These are two rather easy ways to accomplish rotating your video. Unfortunately, Windows Live Movie Maker doesn’t give you a lot of  options for output. If you want to output to a file, your only choice is WMV format or DVD. However, previous versions will also allow you to export to AVI. How-To Geek’s Install Windows Live Essentials In Windows 7 Article.

• SQL – Quick Start with Admin Sections of NuoDB – Manage NuoDB Database

  - by Pinal Dave

  In the yesterday’s blog post we have seen that it is extremely easy to install the NuoDB database on your local machine. Now that the application is properly set up, let us explore NuoDB a bit more and get you familiar with the how it works and what the important areas of the NuoDB are that you should learn. As we have already installed NuoDB, now we will quickly start with two of the important areas in NuoDB: 1) Admin and 2) Explorer. In this blog post I will explore how the Admin Section of the NuoDB Console works.  In the next blog post we will learn how the Explorer Section works. Let us go to the NuoDB Console by typing the following URL in your browser: http://localhost:8080/ It will bring you to the following screen: On this screen you can see a big Start QuickStart button. Click on the button and it will bring you to following screen. On this screen you will find very important information about Domain and Database Settings. It is our habit that we do not read what is written on the screen and keep on clicking on continue without reading. While we are familiar with most wizards, we can often miss the very important message on the screen. Please note the information of Domain Settings and Database Settings from the following screen before clicking on Create Database. Domain Settings User: quickstart Password: quickstart Database Settings User: dba Password: goalie Database: test Schema: HOCKEY Once you click on the Create Database button it will immediately start creating sample database. First, it will start a Storage Manager and right after that it will start a Transaction Engine. Once the engine is up, it will Create a Schema and Sample Data. On the success of the creating the sample database it will show the following screen. Now is the time where we can explore the NuoDB Admin or NuoDB Explorer. If you click on Admin, it will first show following login screen. Enter for the username “domain” and for the password “bird”. Alternatively you can enter “quickstart”  twice for username and password.  It works as too. Once you enter into the Admin Section, on the left side you can see information about NuoDB and Admin Console and on the right side you can see the domain overview area. From this Administrative section you can do any of the following tasks: Create a view of the entire domain Add and remove databases Start and stop NuoDB Transaction Engines and Storage Managers Monitor transaction across all the NuoDB databases On the right side of the Admin Section we can see various information about a particular NuoDB domain. You can quickly view various alerts, find out information about the number of host machines that are provisioned for the domain, and see the number of databases and processes that are running in the domain. If you click on the “1 host” link you will be able to see various processes, CPU usage and other information. In the Processes Section you can see that there are two different types of processes. The first process (where you can see the floppy drive icon) represents a running Storage Manager process and the second process a running Transaction Engine process. You can click on the links for the Storage Manager and Transaction Engine to see further statistical details right down to the last byte of the data. There are various charts available for analysis as well. I think the product is quite mature and the user can add different monitor charts to the Admin section. Additionally, the Admin section is the place where you can create and manage new databases. I hope today’s tutorial gives you enough confidence that you can try out NuoDB and checkout various administrative activities with the database. I am personally impressed with their dashboard related to various counters. For more information about how the NuoDB architecture works and what a Storage Manager or Transaction Engine does, check out this short video with NuoDB CTO Seth Proctor:  In the next blog post, we will try out the Explorer section of NuoDB, which allows us to run SQL queries and write SQL code.  Meanwhile, I strongly suggest you download and install NuoDB and get yourself familiar with the product.

• Kanban Tools Review

  - by GeekAgilistMercenary

  The first two sessions on Sunday were Collaboration and why it is so hard and the following, which was a perfect following session was on Kanban.  While in that second session two online Saas Style Tools were mentioned; AgileZen and Leankit.  I decided right then and there that I would throw together some first impressions and setup some sample projects.  I did this by setting up an account and creating the projects. Agile Zen Account Creation Setting up the initial account required an e-mail verification, which is understandable.  Within a few seconds it was mailed out and I was logged in. Setting Up the Kanban Board The initial setup of the board was pretty easy.  I maybe clicked around an extra few times, but overall everything I needed to use the tool was immediately available.  The representation of everything was very similar to what one expects in a real Kanban Board too.  This is a HUGE plus, especially if a team is smart and places this tool in a centrally viewable area to allow for visibility. Each of the board items is just like a post it, being blue, grey, green, pink, or one of another few colors.  Dragging them onto each swim lane on the board was flawless, making changes through the work super easy and intuitive. The other thing I really liked about AgileZen is that the Kanban Board had the swim lanes setup immediately.  One can change them, but when you know you immediately need a Ready Lane, Working Lane, and a Complete Lane it is nice to just have them right in front of you in the interface.  In addition, the Backlog is simply a little tab on the left hand side.  This is perfect for the Backlog Queue.  Out of the way, with the focus on the primary items. Once  I got the items onto the board I was easily able to get back to the actual work at hand versus playing around with the tool.  The fact that it was so easy to use, fast and easy UX, and overall a great layout put me back to work on things I needed to do versus sitting a playing with the tool.  That, in the end is the key to using these tools. LeanKit Kanban Account Creation Setting up the account got me straight into the online tool.  This I thought was pretty cool. Setting Up the Kanban Board Setting up the Kanban Board within Leankit was a bit of trouble.  There were multiple UX issues in regard to process and intuitiveness.  The Leankit basically forces one to design the whole board first, making no assumptions about how the board should look.  The swim lanes in my humble opinion should be setup immediately without any manipulation with the most common lanes;  ready, working, and complete. The other UX hiccup that I had a problem with is that as soon as I managed to get the swim lanes into place, I wanted to remove the redundant Backlog Lane.  The Backlog Lane, or Backlog Bucket should be somewhere that I accidentally added as a lane.  Then on top of that I screwed up and added an item inside the lane, which then prevented me from deleting the lane.  I had to go back out of the lane manipulation, remove the item, and then remove the excess lane.  Summary Leankit wasn't a bad interface, it just wasn't as good as AgileZen.  The AgileZen interface was just better UX design overall.  AgileZen also presents a much better user interface graphical design all together.  It is much closer to what the Kanban Board would look like if it were a physical Kanban Board.  Since one of the HUGE reasons for Kanban is to increase visibility, the fact the design is similar to what a real Kanban Board is actually a pretty big deal. This is an image (click for larger) that shows the two Kanban Boards side by side.  The one on the left is AgileZen and the right is Leankit. Original Entry

• SQL SERVER – Installing SQL Server Data Tools and SSRS

  - by Pinal Dave

  This example is from the Beginning SSRS by Kathi Kellenberger. Supporting files are available with a free download from the www.Joes2Pros.com web site. If you have installed SQL Server, but are missing the Data Tools or Reporting Services Double-click the SQL Server 2012 installation media. Click the Installation link on the left to view the Installation options. Click the top link New SQL Server stand-alone installation or add features to an existing installation. Follow the SQL Server Setup wizard until you get to the Installation Type screen. At that screen, select Add features to an existing instance of SQL Server 2012. Click Next to move to the Feature Selection page. Select Reporting Services – Native and SQL Server Data Tools. If the Management Tools have not been installed, go ahead and choose them as well. Continue through the wizard and reboot the computer at the end of the installation if instructed to do so. Configure Reporting Services If you installed Reporting Services during the installation of the SQL Server instance, SSRS will be configured automatically for you. If you install SSRS later, then you will have to go back and configure it as a subsequent step. Click Start > All Programs > Microsoft SQL Server 2012 > Configuration Tools > Reporting Services Configuration Manager > Connect on the Reporting Services Configuration Connection dialog box. On the left-hand side of the Reporting Services Configuration Manager, click Database. Click the Change Database button on the right side of the screen. Select Create a new report server database and click Next. Click through the rest of the wizard accepting the defaults. This wizard creates two databases: ReportServer, used to store report definitions and security, and ReportServerTempDB which is used as scratch space when preparing reports for user requests. Now click Web Service URL on the left-hand side of the Reporting Services Configuration Manager. Click the Apply button to accept the defaults. If the Apply button has been grayed out, move on to the next step. This step sets up the SSRS web service. The web service is the program that runs in the background that communicates between the web page, which you will set up next, and the databases. The final configuration step is to select the Report Manager URL link on the left. Accept the default settings and click Apply. If the Apply button was already grayed out, this means the SSRS was already configured. This step sets up the Report Manager web site where you will publish reports. You may be wondering if you also must install a web server on your computer. SQL Server does not require that the Internet Information Server (IIS), the Microsoft web server, be installed to run Report Manager. Click Exit to dismiss the Reporting Services Configuration Manager dialog box. Tomorrow’s Post Tomorrow’s blog post will show how to create your first report using the Report Wizard. If you want to learn SSRS in easy to simple words – I strongly recommend you to get Beginning SSRS book from Joes 2 Pros.

• F1 Pit Pragmatics

  - by mikef

  "I hate computers. No, really, I hate them. I love the communications they facilitate, I love the conveniences they provide to my life. but I actually hate the computers themselves." - Scott Merrill, 'I hate computers: confessions of a Sysadmin' If Scott's goal was to polarize opinion and trigger raging arguments over the 'real reasons why computers suck', then he certainly succeeded. Impassioned vitriol sits side-by-side with rational debate. Yet Scott's fundamental point is absolutely on the money - Computers are a means to an end. The IT industry is finally starting to put weight behind the notion that good User Experience is an absolutely crucial goal, a cause championed by the likes of Microsoft's Bill Buxton, and which Apple's increasingly ubiquitous touch screen interface exemplifies. However, that doesn't change the fact that, occasionally, you just have to man up and deal with complex systems. In fact, sometimes you just need to sacrifice everything else in the name of performance. You'll find a perfect example of this Faustian bargain in Trevor Clarke's fascinating look into the (diabolical) IT infrastructure of modern F1 racing - high performance, high availability. high everything. To paraphrase, each car has up to 100 sensors, transmitting around 30Gb of data over the course of a race (70% in real-time). This data is then processed by no less than 3 servers (per car) so that the engineers in the pit have access to telemetry, strategy information, timing feeds, a connection back to the operations room in the team's home base - the list goes on. All of this while the servers are exposed "to carbon dust, oil, vibration, rain, heat, [and] variable power". Now, this is admittedly an extreme context where there's no real choice but to use complex systems where ease-of-use is, at best, a secondary concern. The flip-side is seen in small-scale personal computing such as that seen in Apple's iDevices, which are incredibly intuitive but limited in their scope. In terms of what kinds of systems they prefer to use, I suspect that most SysAdmins find themselves somewhere along this axis of Power vs. Usability, and which end of this axis you resonate with also hints at where you think the IT industry should focus its energy. Do you see yourself in the F1 pit, making split-second decisions, wrestling with information flows and reticent hardware to bend them to your will? If so, I imagine you feel that computers are subtle tools which need to be tuned and honed, using the advanced knowledge possessed only by responsible SysAdmins (If you have an iPhone, I suspect it's jail-broken). If the machines throw enigmatic errors, it's the price of flexibility and raw power. Alternatively, would you prefer to have your role more accessible, with users empowered by knowledge, spreading the load of managing IT environments? In that case, then you want hardware and software to have User Experience as their primary focus, and are of the "means to an end" school of thought (you're probably also fed up with users not listening to you when you try and help). At its heart, the dichotomy is between raw power (which might be difficult to use) and ease-of-use (which might have some limitations, but you can be up and running immediately). Of course, the ultimate goal is a fusion of flexibility, power and usability all in one system. It's achievable in specific software environments, and Red Gate considers it a target worth aiming for, but in other cases it's a goal right up there with cold fusion. I think it'll be a long time before we see it become ubiquitous. In the meantime, are you Power-Hungry or a Champion of Usability? Cheers, Michael Francis Simple Talk SysAdmin Editor

• Orchestrating the Virtual Enterprise, Part II

  - by Kathryn Perry

  A guest post by Jon Chorley, Oracle's CSO & Vice President, SCM Product Strategy Almost everyone has ordered from Amazon.com at one time or another. Our orders are as likely to be fulfilled by third parties as they are by Amazon itself. To deliver the order promptly and efficiently, Amazon has to send it to the right fulfillment location and know the availability in that location. It needs to be able to track status of the fulfillment and deal with exceptions. As a virtual enterprise, Amazon's operations, using thousands of trading partners, requires a very different approach to fulfillment than the traditional 'take an order and ship it from your own warehouse' model. Amazon had no choice but to develop a complex, expensive and custom solution to tackle this problem as there used to be no product solution available. Now, other companies who want to follow similar models have a better off-the-shelf choice -- Oracle Distributed Order Orchestration (DOO).  Consider how another of our customers is using our distributed orchestration solution. This major airplane manufacturer has a highly complex business and interacts regularly with the U.S. Government and major airlines. It sits in the middle of an intricate supply chain and needed to improve visibility across its many different entities. Oracle Fusion DOO gives the company an orchestration mechanism so it could improve quality, speed, flexibility, and consistency without requiring an organ transplant of these highly complex legacy systems. Many retailers face the challenge of dealing with brick and mortar, Web, and reseller channels. They all need to be knitted together into a virtual enterprise experience that is consistent for their customers. When a large U.K. grocer with a strong brick and mortar retail operation added an online business, they turned to Oracle Fusion DOO to bring these entities together. Disturbing the Peace with Acquisitions Quite often a company's ERP system is disrupted when it acquires a new company. An acquisition can inject a new set of processes and systems -- or even introduce an entirely new business like Sun's hardware did at Oracle. This challenge has been a driver for some of our DOO customers. A large power management company is using Oracle Fusion DOO to provide the flexibility to rapidly integrate additional products and services into its central fulfillment operation. The Flip Side of Fulfillment Meanwhile, we haven't ignored similar challenges on the supply side of the equation. Specifically, how to manage complex supply in a flexible way when there are multiple trading parties involved? How to manage the supply to suppliers? How to manage critical components that need to merge in a tier two or tier three supply chain? By investing in supply orchestration solutions for the virtual enterprise, we plan to give users better visibility into their network of suppliers to help them drive down costs. We also think this technology and full orchestration process can be applied to the financial side of organizations. An example is transactions that flow through complex internal structures to minimize tax exposure. We can help companies manage those transactions effectively by thinking about the internal organization as a virtual enterprise and bringing the same solution set to this internal challenge.  The Clear Front Runner No other company is investing in solving the virtual enterprise supply chain issues like Oracle is. Oracle is in a unique position to become the gold standard in this market space. We have the infrastructure of Oracle technology. We already have an Oracle Fusion DOO application which embraces the best of what's required in this area. And we're absolutely committed to extending our Fusion solution to other use cases and delivering even more business value.

• Determining explosion radius damage - Circle to Rectangle 2D

  - by Paul Renton

  One of the Cocos2D games I am working on has circular explosion effects. These explosion effects need to deal a percentage of their set maximum damage to all game characters (represented by rectangular bounding boxes as the objects in question are tanks) within the explosion radius. So this boils down to circle to rectangle collision and how far away the circle's radius is from the closest rectangle edge. I took a stab at figuring this out last night, but I believe there may be a better way. In particular, I don't know the best way to determine what percentage of damage to apply based on the distance calculated. Note : All tank objects have an anchor point of (0,0) so position is according to bottom left corner of bounding box. Explosion point is the center point of the circular explosion. TankObject * tank = (TankObject*) gameSprite; float distanceFromExplosionCenter; // IMPORTANT :: All GameCharacter have an assumed (0,0) anchor if (explosionPoint.x < tank.position.x) { // Explosion to WEST of tank if (explosionPoint.y <= tank.position.y) { //Explosion SOUTHWEST distanceFromExplosionCenter = ccpDistance(explosionPoint, tank.position); } else if (explosionPoint.y >= (tank.position.y + tank.contentSize.height)) { // Explosion NORTHWEST distanceFromExplosionCenter = ccpDistance(explosionPoint, ccp(tank.position.x, tank.position.y + tank.contentSize.height)); } else { // Exp center's y is between bottom and top corner of rect distanceFromExplosionCenter = tank.position.x - explosionPoint.x; } // end if } else if (explosionPoint.x > (tank.position.x + tank.contentSize.width)) { // Explosion to EAST of tank if (explosionPoint.y <= tank.position.y) { //Explosion SOUTHEAST distanceFromExplosionCenter = ccpDistance(explosionPoint, ccp(tank.position.x + tank.contentSize.width, tank.position.y)); } else if (explosionPoint.y >= (tank.position.y + tank.contentSize.height)) { // Explosion NORTHEAST distanceFromExplosionCenter = ccpDistance(explosionPoint, ccp(tank.position.x + tank.contentSize.width, tank.position.y + tank.contentSize.height)); } else { // Exp center's y is between bottom and top corner of rect distanceFromExplosionCenter = explosionPoint.x - (tank.position.x + tank.contentSize.width); } // end if } else { // Tank is either north or south and is inbetween left and right corner of rect if (explosionPoint.y < tank.position.y) { // Explosion is South distanceFromExplosionCenter = tank.position.y - explosionPoint.y; } else { // Explosion is North distanceFromExplosionCenter = explosionPoint.y - (tank.position.y + tank.contentSize.height); } // end if } // end outer if if (distanceFromExplosionCenter < explosionRadius) { /* Collision :: Smaller distance larger the damage */ int damageToApply; if (self.directHit) { damageToApply = self.explosionMaxDamage + self.directHitBonusDamage; [tank takeDamageAndAdjustHealthBar:damageToApply]; CCLOG(@"Explsoion-> DIRECT HIT with total damage %d", damageToApply); } else { // TODO adjust this... turning out negative for some reason... damageToApply = (1 - (distanceFromExplosionCenter/explosionRadius) * explosionMaxDamage); [tank takeDamageAndAdjustHealthBar:damageToApply]; CCLOG(@"Explosion-> Non direct hit collision with tank"); CCLOG(@"Damage to apply is %d", damageToApply); } // end if } else { CCLOG(@"Explosion-> Explosion distance is larger than explosion radius"); } // end if } // end if Questions: 1) Can this circle to rect collision algorithm be done better? Do I have too many checks? 2) How to calculate the percentage based damage? My current method generates negative numbers occasionally and I don't understand why (Maybe I need more sleep!). But, in my if statement, I ask if distance < explosion radius. When control goes through, distance/radius must be < 1 right? So 1 - that intermediate calculation should not be negative. Appreciate any help/advice!

• How to undo a changeset using tf.exe rollback

  - by Tarun Arora

  Technorati Tags: Team Foundation Server 2010,Team Foundation Utilities,TFS2010   Oh no! Did you just check in a changeset in to TFS and realized that you need to roll back the changeset because the changes were suppose to go in a different branch? Or did you just accidently merge a wrong changeset in your release branch? There are several ways to undo the damage, Manual: Yes, we all just hate this word but for the record you could manually rollback the changes. Get Specific version on the branch and chose the changeset prior to the one you checked in. After that check out all the files in the changeset and check them in. During the check in you will receive a conflict. At this point choose ‘Keep local changes’ in the conflict resolution window and check in the files. Automated: Yes, we just love it! TFS comes with a very powerful command line utility ‘tf.exe’ that gives you the ability to rollback the effects of one or more changesets to one or more version-controlled items. This command does not remove the changesets from an item's version history. Instead, this command creates in your workspace a set of pending changes that negate the effects of the changesets that you specify. Syntax tf rollback /toversion:VersionSpec ItemSpec [/recursive] [/lock:none|checkin|checkout] [/version:versionspec] [/keepmergehistory] [/login:username,[password]] [/noprompt] tf rollback /changeset:ChangesetFrom~ChangesetTo [ItemSpec] [/recursive] [/lock:none|checkin|checkout] [/version:VersionSpec] [/keepmergehistory] [/noprompt] [/login:username,[password]]   I’ll explain this with an example. Your workspace is at the location C:\myWorkspace You want to rollback changeset # 145621 C:\Workspace\MyBranch>tf.exe rollback /changeset:145621 /recursive How do i rollback/undo a series of changesets? You can also rollback a range of changesets by using the following C:\Workspace\MyBranch>tf.exe rollback /changeset:145601~145621 /recursive This will check out the files in the version control and you should be able to see them in the pending changes. Go on check them in to undo the specific changeset that you just rolled back. Do you completely want to get rid of the changeset from all future merges between the two branches? /KeepMergeHistory: This option has an effect only if one or more of the changesets that you are rolling back include a branch or merge change. Specify this option if you want future merges between the same source and the same target to exclude the changes that you are rolling back. Errors “If you get the message ‘Unable to determine the workspace.’ You may be able to correct this by running ‘tf worksapces /collection:TeamProjectCollectionUrl’” you are in the wrong directory. Make sure that you run the ‘tf rollback’ command from the directory of your workspace.   Status Exit Code Description 0 The operation rolled back all items successfully. 1 The operation rolled back at least one item successfully but could not roll back one or more items. 100 The operation could not roll back any items.   To use the command you must have the Read, Check Out, and Check In permissions set to Allow. So, have you been in a rollback undo situation before?   Share this post :

• The Power to Control Power

  - by speakjava

  I'm currently working on a number of projects using embedded Java on the Raspberry Pi and Beagle Board.  These are nice and small, so don't take up much room on my desk as you can see in this picture. As you can also see I have power and network connections emerging from under my desk.  One of the (admittedly very minor) drawbacks of these systems is that they have no on/off switch.  Instead you insert or remove the power connector (USB for the RasPi, a barrel connector for the Beagle).  For the Beagle Board this can potentially be an issue; with the micro-SD card located right next to the connector it has been known for people to eject the card when trying to power off the board, which can be quite serious for the hardware. The alternative is obviously to leave the boards plugged in and then disconnect the power from the outlet.  Simple enough, but a picture of underneath my desk shows that this is not the ideal situation either. This made me think that it would be great if I could have some way of controlling a mains voltage outlet using a remote switch or, even better, from software via a USB connector.  A search revealed not much that fit my requirements, and anything that was close seemed very expensive.  Obviously the only way to solve this was to build my own.Here's my solution.  I decided my system would support both control mechanisms (remote physical switch and USB computer control) and be modular in its design for optimum flexibility.  I did a bit of searching and found a company in Hong Kong that were offering solid state relays for 99p plus shipping (£2.99, but still made the total price very reasonable).  These would handle up to 380V AC on the output side so more than capable of coping with the UK 240V supply.  The other great thing was that being solid state, the input would work with a range of 3-32V and required a very low current of 7.5mA at 12V.  For the USB control an Arduino board seemed the obvious low-cost and simple choice.  Given the current requirments of the relay, the Arduino would not require the additional power supply and could be powered just from the USB.Having secured the relays I popped down to Homebase for a couple of 13A sockets, RS for a box and an Arduino and Maplin for a toggle switch.  The circuit is pretty straightforward, as shown in the diagram (only one output is shown to make it as simple as possible).  Originally I used a 2 pole toggle switch to select the remote switch or USB control by switching the negative connections of the low voltage side.  Unfortunately, the resistance between the digital pins of the Arduino board was not high enough, so when using one of the remote switches it would turn on both of the outlets.  I changed to a 4 pole switch and isolated both positive and negative connections. IMPORTANT NOTE: If you want to follow my design, please be aware that it requires working with mains voltages.  If you are at all concerned with your ability to do this please consult a qualified electrician to help you.It was a tight fit, especially getting the Arduino in, but in the end it all worked.  The completed box is shown in the photos. The remote switch was pretty simple just requiring the squeezing of two rocker switches and a 9V battery into the small RS supplied box.  I repurposed a standard stereo cable with phono plugs to connect the switch box to the mains outlets.  I chopped off one set of plugs and wired it to the rocker switches.  The photo shows the RasPi and the Beagle board now controllable from the switch box on the desk. I've tested the Arduino side of things and this works fine.  Next I need to write some software to provide an interface for control of the outlets.  I'm thinking a JavaFX GUI would be in keeping with the total overkill style of this project.

• What is the best practice, point of view of well experienced developers

  - by Damien MIRAS

  My manager pushes me to use his self defined best practices. All of these practices are based on is own assumptions. I disagree with them and I would like to have some feedback of well experienced people about these practices. I would prefer answers from people involved in the maintenance of huge products and people whom have maintained the product for years. Developers with 15+ years of experience are preferred because my manager has that much experience himself. I have 7 years of experience. Here are the practices he wants me to use: never extends classes, use composition and interface instead because extending classes are unmaintainable and difficult to debug. What I think about that Extend when needed, respect "Liskov's Substitution Principle" and you'll never be stuck with a problem, but prefer composition and decoration. I don't know any serious project which has banned inheriting, sometimes it's impossible to not use that, i.e. in a UI framework. Design patterns are just unusable. In PHP, for simple use cases (for example a user needs a web interface to view a database table), his "best practice" is: copy some random php code wich we own, paste and modify it, put html and php code in same file, never use classes in PHP, it doesn't work well for small jobs, and in fact it doesn't work well at all, there is no good tool to work with. Copy & paste PHP code is good practice for maintenance because scripts are independent, if you have a bug somewhere you can fix it without side effects. What I think about that: NEVER EVER COPY code or do it because you have five minutes to deliver something, you will do some refactoring after that. Copy & paste code is a beginners error, if you have errors you'll have the error everywhere any time you have pasted it's a nightmare to maintain. If you repsect the "Open Close Principle" you'll rarely get edge effects, use unit test if you are afraid of that. For small jobs in PHP use at least something you get or write the HTML separately from the PHP code and reuse it any time you need it. Classes in PHP are mature, not as mature as other languages like python or java, but they are usable. There is tools to work with classes in PHP like Zend Studio that work very well. The use of classes or not depends not on the language you use but the programming paradigm you have choosen. I'm a OOP developer, I use PHP5, why do I have to shoot myself in the foot? When you find a simple bug in the code, and you can fix it simply, if you are not working on the code where you have found it, never fix it, even if it takes 5 seconds. He says to me his "best practices" are driven by the fact that he has a lot of experience in maintaining software in production (14 years) and he now knows what works and what doesn't work, what the community says is a fad, and the people advocating such principles as never copy & paste code, are not evolved in maintaining applications. What I think about that: If you find a bug fix it if you can do it quickly inform the people who've touched that code before, check if you have not introduced a new bug, ideally add a unit test for it. I currently work on a web commerce project, which serves 15k unique users per day. The code base has to be maintained and has been maintained this way since 2005. Ideally you include a short description of your position and experience in terms of years effectively maintaining an application which has been in production for real.

• Using Solaris zfs + iscsi targets with Oracle VM

  - by wim.coekaerts

  I was playing with my Oracle VM setup and needed some shared storage that was block based. I did not have a storage array available but I did have a solaris box, that I use for Oracle VDI, available. I set up a few iscsi targets on this solaris server and exported them to my 2 Oracle VM servers. Here's how I did this : (1) On the solaris side : # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT rpool 544G 129G 415G 23% ONLINE - I just have a simple zpool, called rpool, on this box. It has plenty of space available for my needs. So I will use rpool and I will create 5 50gb vols : zfs create -V 50G rpool/ovm1 zfs create -V 50G rpool/ovm2 zfs create -V 50G rpool/ovm3 zfs create -V 50G rpool/ovm4 zfs create -V 50G rpool/ovm5 I want to use these volumes for iscsi so I have to enable them as shared iscsi devices : zfs set shareiscsi=on rpool/ovm1 zfs set shareiscsi=on rpool/ovm2 zfs set shareiscsi=on rpool/ovm3 zfs set shareiscsi=on rpool/ovm4 zfs set shareiscsi=on rpool/ovm5 The command iscsitadm list target should list these devices so make sure they show up. # iscsitadm list target Target: rpool/ovm1 iSCSI Name: iqn.1986-03.com.sun:02:896c766c-0943-4da5-d47e-9575b5a0be36 Connections: 2 Target: rpool/ovm2 iSCSI Name: iqn.1986-03.com.sun:02:a3116b46-73e0-e8c2-e80c-9a4f71aff069 Connections: 2 Target: rpool/ovm3 iSCSI Name: iqn.1986-03.com.sun:02:a838c400-2730-c0d6-f2c2-ee186a0261c1 Connections: 2 Target: rpool/ovm4 iSCSI Name: iqn.1986-03.com.sun:02:2e046afb-d66d-4f3f-c5de-8115e0ddd931 Connections: 2 Target: rpool/ovm5 iSCSI Name: iqn.1986-03.com.sun:02:66109fbe-81ac-ef05-f85e-ab8c1f34cb43 Connections: 2 At this point I want to make sure that I have some access control on these devices. To make it easier, I will create an alias for my 2 servers and use the alias for the ACL. get the iqn from the 2 servers on my 2 ovm servers (wcoekaer-srv1, wcoekaer-srv2) get the content of /etc/iscsi/initiatorname.iscsi (for each server) InitiatorName=iqn.1986-03.com.sun:01:2a7526f0ffff On the solaris side create the aliases : iscsitadm create initiator -n iqn.1986-03.com.sun:01:2a7526f0ffff wcoekaer-srv1 iscsitadm create initiator -n iqn.1986-03.com.sun:01:e31b08110f1 wcoekaer-srv5 Add the ACL to the targets : iscsitadm modify target -l wcoekaer-srv1 rpool/ovm1 iscsitadm modify target -l wcoekaer-srv1 rpool/ovm2 iscsitadm modify target -l wcoekaer-srv1 rpool/ovm3 iscsitadm modify target -l wcoekaer-srv1 rpool/ovm4 iscsitadm modify target -l wcoekaer-srv1 rpool/ovm5 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm1 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm2 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm3 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm4 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm5 (2) the Oracle VM side On each server just do 2 simple things : # iscsiadm -m discovery -t sendtargets -p ca-vdi1 where ca-vdi1 is my solaris server name # service iscsi restart When I do cat /proc/partitions on my servers I will see the devices show up # cat /proc/partitions major minor #blocks name 8 0 160836480 sda 8 1 104391 sda1 8 2 3148740 sda2 8 3 1052257 sda3 253 0 6377804 dm-0 253 1 6377804 dm-1 253 2 6377804 dm-2 8 16 52428800 sdb 8 32 52428800 sdc 8 48 52428800 sdd 8 80 52428800 sdf 8 64 52428800 sde These 5 new devices sd[b..f] are shared storage for Oracle VM and can be used to pass through to the VM's as phy: devices or put ocfs2 on it and use as shared filesystem storage for dom0 repositories. I am setting up an 11gR2 rac template (the cool stuff Saar did) so I am using my devices to create a 2 node RAC cluster with phy: devices.

• Minimum team development sizes

  - by MarkPearl

  Disclaimer - these are observations that I have had, I am not sure if this follows the philosophy of scrum, agile or whatever, but most of these insights were gained while implementing a scrum scenario. Two is a partnership, three starts a team For a while I thought that a team was anything more than one and that scrum could be effective methodology with even two people. I have recently adjusted my thinking to a scrum team being a minimum of three, so what happened to two and what do you call it? For me I consider a group of two people working together a partnership - there is value in having a partnership, but some of the dynamics and value that you get from having a team is lost with a partnership. Avoidance of a one on one confrontation The first dynamic I see missing in a partnership is the team motivation to do better and how this is delivered to individuals that are not performing. Take two highly motivated individuals and put them together and you will typically see them continue to perform. Now take a situation where you have two individuals, one performing and one not and the behaviour is totally different compared to a team of three or more individuals. With two people, if one feels the other is not performing it becomes a one on one confrontation. Most people avoid confrontations and so nothing changes. Compare this to a situation where you have three people in a team, 2 performing and 1 not the dynamic is totally different, it is no longer a personal one on one confrontation but a team concern and people seem more willing to encourage the individual not performing and express their dissatisfaction as a team if they do not improve. Avoiding the effects of Tuckman’s Group Development Theory If you are not familiar with Tuckman’s group development theory give it a read (http://en.wikipedia.org/wiki/Tuckman's_stages_of_group_development) In a nutshell with Tuckman’s theory teams go through these stages of Forming, Storming, Norming & Performing. You want your team to reach and remain in the Performing stage for as long as possible - this is where you get the most value. When you have a partnership of two and you change the individuals in the partnership you basically do a hard reset on the partnership and go back to the beginning of Tuckman’s model each time. This has a major effect on the performance of a team and what they can deliver. What I have seen is that you reduce the effects of Tuckman's theory the more individuals you have in the team (until you hit the maximum team size in which other problems kick in). While you will still experience Tuckman's theory with a team of three, the impact will be greatly reduced compared to two where it is guaranteed every time a change occurs. It's not just in the numbers, it's in the people One final comment - while the actual numbers of a team do play a role, the individuals in the team are even more important - ideally you want to keep individuals working together for an extended period. That doesn't mean that you never change the individuals in a team, or that once someone joins a team they are stuck there - there is value in an individual moving from team to team and getting cross pollination, but the period of time that an individual moves should be in month's or years, not days or weeks. Why? So why is it important to know this? Why is it important to know how a team works and what motivates them? I have been asking myself this question for a while and where I am at right now is this… the aim is to achieve the stage where the sum of the total (team) is greater than the sum of the parts (team members). This is why we form teams and why understanding how they work is a challenge and also extremely stimulating.

• Admin Panel like Custom Framework

  - by bhuvin

  I want to Create a Framework , like Admin panel , which can rule almost all the aspects of what is shown on the frontend. For an (most basic) example: If suppose the links which are to be shown in a navigation area is passed from the server, with the order and the url , etc. The whole aim is to save the time on the tedious tasks. You can just start creating menus and start assigning pages to it. Give a url, actual files which are to be rendered (in case of static files.), in case of dynamic files, giving the file accordingly. And all this is fully server side manageable using different portlets, sort of things. So basic Roadmap is having : Areas like: Header Area - Which can contain logos, links etc. Navigation Area - Which can contains links and submenus. Content Area - Now this is where the tricky part is that that it has zones like: left, center & right. It contains Order in which it has to be displayed. So, when someday we want to change the way the articles appear on the page, we can do so easily, without any deployments. Now these zones can have n number of internal elements, like the word cloud, or the advertisement area. Footer Area: Again similar as Header Area. Currently there is a preexisting custom framework, which uses XSLT files for pulling out data from the server side. And it has the above capabilities. For example: If there's a grid it will be having a <table> tag embedded in the XSLT file. Now whatever might be the source of the data, we serialize this as XML and give it to the XSLT file and the html is derived from this and is appended to the layer in a page. The problem with this approach is: The XSLT conversion is occurring on the server side, so the server is responsible for getting the data, running XSLT transform, and append the html generated to the layer div. So, according to me, firstly this isn't the server's concern to do so. Secondly for larger applications this might be slower. Debugging isn't possible for XSLT transformation. So, whenever we face problems with data its always a bit of a trial & error method. Maintaining it is a bit of an eerie job i.e. styling changes, and other stuff. Adding dynamic values. Like JavaScript can't actually be very easily used in this. Secondly, we can't use JQuery or any other libraries with this since this is all occurring on the server. For now what I have thought about is using Templating - Javascript - JSON combination in place of XSLT, this will be offloaded to the client and the rendering will take place accordingly. This could solve the above problems and also could add mobile support for the same. Only problem which I could think of is that: It is much work and adding new portlets on the go needs to be looked into. What could be the alternatives for this? What kind of problems are there with the JavaScript approach? What are the different ways to implement the same? Are there any existing frameworks for similar usage?

• How do you go from a so so programmer to a great one? [closed]

  - by Cervo

  How do you go from being an okay programmer to being able to write maintainable clean code? For example David Hansson was writing Basecamp when in the process he created Rails as part of writing Basecamp in a clean/maintainable way. But how do you know when there is value in a side project like that? I have a bachelors in computer science, and I am about to get a masters and I will say that colleges teach you to write code to solve problems, not neatly or anything. Basically you think of a problem, come up with a solution, and write it down...not necessarily the most maintainable way in the world. Also my first job was in a startup, and now my third is in a small team in a large company where the attitude was/is get it done yesterday (also most of my jobs are mainly database development with SQL with a few ASP.NET web pages/.NET apps on the side). So of course cut/paste is more favored than making things more cleanly. And they would rather have something yesterday even if you have to rewrite it next month rather than to have something in a week that lasts for a year. Also spaghetti code turns up all over the place, and it takes very smart people to write/understand/maintain spaghetti code...However it would be better to do things so simple/clean that even a caveman/woman could do maintenance. Also I get very bored/unmotivated having to go modify the same things cut/pasted in a few locations. Is this the type of skill that you need to learn by working with a serious software organization that has an emphasis on maintenance and maybe even an architect who designs a system architecture and reviews code? Could you really learn it by volunteering on an open source project (it seems to me that a full time programmer job is way more practice than a few hours a week on an open source project)? Is there some course where you can learn this? I can attest that graduate school and undergraduate school do not really emphasize clean software at all. They just teach the structures/algorithms and then send you off into the world to solve problems. Overall I think the first thing is learning to write clean/maintainable code within the bounds of the project in order to become a good programmer. Then the next thing is learning when you need to do a side project (like a framework) to make things more maintainable/clean even while you still deliver things for the deadline in order to become a great programmer. For example, you are making an SQL report and someone gives you 100 calculations for individual columns. At what point does it make sense to construct a domain specific language to encode the rules in simply and then generate all the SQL as opposed to cut/pasting the query from the table a bunch of times and then adjusting each query to do the appropriate calculations. This is the type of thing I would say a great programmer would know. He/she would maybe even know ways to avoid the domain specific language and to still do all the calculations without creating an unmaintainable mess or a ton of repetitive code to cut/paste everywhere.

• DRY Validation with MVC2

  - by Matthew

  Hi All, I'm trying to figure out how I can define validation rules for my domain objects in one single location within my application but have run in to a snag... Some background: My location has several parts: - Database - DAL - Business Logic Layer - SOAP API Layer - MVC website The MVC website accesses the database via the SOAP API, just as third parties would. We are using server and and client side validation on the MVC website as well as in the SOAP API Layer. To avoid having to manually write client side validation we are implementing strongly typed views in conjunction with the Html.TextBoxFor and Html.ValidationMessageFor HTML helpers, as shown in Step 3 here. We also create custom models for each form where one form takes input for multiple domain objects. This is where the problem begins, the HTML helpers read from the model for the data annotation validation attributes. In most cases our forms deal with multiple domain objects and you can't specify more than one type in the <%@Page ... Inherits="System.Web.Mvc.ViewPage" % page directive. So we are forced to create a custom model class, which would mean duplicating validation attributes from the domain objects on to the model class. I've spent quite some time looking for workarounds to this, such has referencing the same MetadataType from both the domain class and the custom MVC models, but that won't work for several reasons: You can only specify one MetadataType attribute per class, so its a problem if a model references multiple domain objects, each with their own metadata type. The data annotation validation code throws an exception if the model class doesn't contain a property that is specified in the referenced MetadataType which is a problem with the model only deals with a subset of the properties for a given domain object. I've looked at other solutions as well but to no avail. If anyone has any ideas on how to achieve a single source for validation logic that would work across MVC client and server side validation functionality and other locations (such as my SOAP API) I would love to hear it! Thanks in advance, Matthew

• MVC2 client/server validation of DateTime/Date using DataAnnotations

  - by Thomas

  The following are true: One of my columns (BirthDate) is of type Date in SQL Server. This very same column (BirthDate) is of type DateTime when EF generates the model. I am using JQuery UI Datepicker on the client side to be able to select the BirthDate. I have the following validation logic in my buddy class: [Required(ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Required")] [RegularExpression(@"\b(0?[1-9]|1[012])[/](0?[1-9]|[12][0-9]|3[01])[/](19|20)?[0-9]{2}\b", ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Invalid")] public virtual DateTime? BirthDate { get; set; } There are two issues with this: This will not pass server side validation (if I enable client side validation it works just fine). I am assuming that this is because the regular expression doesn't take into account hours, minutes, seconds as the value in the text box has already been cast as a DateTime on the server by the time validation occurs. If data already exists in the database and is read into the model and displayed on the page the BirthDate field shows hours, minutes, seconds in my text box (which I don't want). I can always use ToShortDateString() but I am wondering if there is some cleaner approach that I might be missing. Thanks

• Autofac WCF integration + sessions

  I am having an ASP.NET MVC 3 application that collaborates with a WCF service, which is hosted using Autofac host factory. Here are some code samples: .svc file: <%@ ServiceHost Language="C#" Debug="true" Service="MyNamespace.IMyContract, MyAssembly" Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf" %> Global.asax of the WCF service project: protected void Application_Start(object sender, EventArgs e) { ContainerBuilder builder = new ContainerBuilder(); //Here I perform all registrations, including implementation of IMyContract AutofacServiceHostFactory.Container = builder.Build(); } Client proxy class constructor (MVC side): ContainerBuilder builder = new ContainerBuilder(); builder.Register(c => new ChannelFactory<IMyContract>( new BasicHttpBinding(), new EndpointAddress(Settings.Default.Url_MyService))) .SingleInstance(); builder.Register(c => c.Resolve<ChannelFactory<IMyContract>>().CreateChannel()) .UseWcfSafeRelease(); _container = builder.Build(); This works fine until I want WCF service to allow or require sessions ([ServiceContract(SessionMode = SessionMode.Allowed)], or [ServiceContract(SessionMode = SessionMode.Required)]) and to share one session with the MVC side. I changed the binding to WSHttpBinding on the MVC side, but I am having different exceptions depending on how I tune it. I also tried changing AutofacServiceHostFactory to AutofacWebServiceHostFactory, with no result. I am not using config file as I am mainly experimenting, not developing real-life application, but I need to study the case. But if you think I can achieve what I need only with config files, then OK, I'll use them. I will provide exception details for each combination of settings if required, I'm omitting them not to make the post too large. Any ideas on what I can do?

• Could not convert JavaScript argument arg 0" nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS

  - by Drahcir

  I am trying to make this captcha jquery plugin to work. The a certain line of code is executed, the error pops up. This is the line of code that causes the error : $(".ajax-fc-" + rand).draggable({ containment: '#ajax-fc-content' }); What I am assuming is that there is some kind of conflict with the javascript reference, but can't determain what. These are the referenes that I am using <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js"></script> <script src="js/ui.core.js"></script> <script src="js/ui.draggable.js"></script> <script src="js/ui.droppable.js"></script> <script src="js/effects.core.js"></script> <script src="js/effects.slide.js"></script>

• How do I fix: InvalidOperationException upon Session timeout in Ajax WebService call

  - by Ngm

  Hi All, We are invoking Asp.Net ajax web service from the client side. So the JavaScript functions have calls like: // The function to alter the server side state object and set the selected node for the case tree. function JSMethod(caseId, url) { Sample.XYZ.Method(param1, param2, OnMethodReturn); } function OnMethodReturn(result) { var sessionExpiry = CheckForSessionExpiry(result); var error = CheckForErrors(result); ... process result } And on the server side in the ".asmx.cs" file: namespace Sample [ScriptService] class XYZ : WebService { [WebMethod(EnableSession = true)] public string Method(string param1, string param2) { if (SessionExpired()) { return sessionExpiredMessage; } . . . } } The website is setup to use form based authentication. Now if the session has expired and then the JavaScript function "JSMethod" is invoked, then the following error is obtained: Microsoft JScript runtime error: Sys.Net.WebServiceFailedException: The server method 'Method' failed with the following error: System.InvalidOperationException-- Authentication failed. This exception is raised by method "function Sys$Net$WebServiceProxy$invoke" in file "ScriptResource.axd": function Sys$Net$WebServiceProxy$invoke { . . . { // In debug mode, if no error was registered, display some trace information var error; if (result && errorObj) { // If we got a result, we're likely dealing with an error in the method itself error = result.get_exceptionType() + "-- " + result.get_message(); } else { // Otherwise, it's probably a 'top-level' error, in which case we dump the // whole response in the trace error = response.get_responseData(); } // DevDiv 89485: throw, not alert() throw Sys.Net.WebServiceProxy._createFailedError(methodName, String.format(Sys.Res.webServiceFailed, methodName, error)); } So the problem is that the exception is raised even before "Method" is invoked, the exception occurs during the creation of the Web Proxy. Any ideas on how to resolve this problem

• InvalidOperationException (Lambda parameter not in scope) when trying to Compile a Lambda Expression

  - by Moshe Levi

  Hello, I'm writing an Expression Parser to make my API more refactor friendly and less error prone. basicaly, I want the user to write code like that: repository.Get(entity => entity.Id == 10); instead of: repository.Get<Entity>("Id", 10); Extracting the member name from the left side of the binary expression was straight forward. The problems began when I tried to extract the value from the right side of the expression. The above snippet demonstrates the simplest possible case which involves a constant value but it can be much more complex involving closures and what not. After playing with that for some time I gave up on trying to cover all the possible cases myself and decided to use the framework to do all the heavy lifting for me by compiling and executing the right side of the expression. the relevant part of the code looks like that: public static KeyValuePair<string, object> Parse<T>(Expression<Func<T, bool>> expression) { var binaryExpression = (BinaryExpression)expression.Body; string memberName = ParseMemberName(binaryExpression.Left); object value = ParseValue(binaryExpression.Right); return new KeyValuePair<string, object>(memberName, value); } private static object ParseValue(Expression expression) { Expression conversionExpression = Expression.Convert(expression, typeof(object)); var lambdaExpression = Expression.Lambda<Func<object>>(conversionExpression); Func<object> accessor = lambdaExpression.Compile(); return accessor(); } Now, I get an InvalidOperationException (Lambda parameter not in scope) in the Compile line. when I googled for the solution I came up with similar questions that involved building an expression by hand and not supplying all the pieces, or trying to rely on parameters having the same name and not the same reference. I don't think that this is the case here because I'm reusing the given expression. I would appreciate if someone will give me some pointers on this. Thank you.

• function to get the file name of an URL

  - by user262325

  Hello everyone I have some source code to get the file name of an url for example: http://www.google.com/a.pdf I hope to get a.pdf because the way to join 2 NSStrings I can get is 'appendString' which only for adding a string at right side, so I planned to check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop the checking, return string fdp.a , after that I change fdp.a to a.pdf source codes are below -(NSMutableString *) getSubStringAfterH : originalString:(NSString *)s0 { NSInteger i,l; l=[s0 length]; NSMutableString *h=[[NSMutableString alloc] init]; NSMutableString *ttt=[[NSMutableString alloc] init ]; for(i=l-1;i>=0;i--) //check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop { ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; if([ttt isEqualToString:@"/"]) { break; } else { [h appendString:ttt]; } } [ttt release]; //below are to change the sequence of char in h // txt.edcba -> abcde.txt NSMutableString *h1=[[[NSMutableString alloc] initWithFormat:@""] autorelease]; for (i=[h length]-1;i>=0;i--) { NSMutableString *t1=[[NSMutableString alloc] init ]; t1=[h substringWithRange:NSMakeRange(i, 1)]; [h1 appendString:t1]; [t1 release]; } [h release]; return h1; } h1 can reuturn the coorect string a.pdf, but if it returns to the codes where it was called, after a while system reports 'double free * set a breakpoint in malloc_error_break to debug' I checked a long time and foudn that if I removed the code ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; everything will be Ok (of course getSubStringAfterH can not returns the corrent result I expected.), no error reported. I try to fix the bug a few hours, but still no clue. Welcome any comment Thanks interdev

• RSA C# Encrypt Java Decrypt

  - by user353030

  Hi guys, In my program (server side - Java) I've created keystore file, with command: keytool -genkey -alias myalias -keyalg RSA -validity 10000 -keystore my.keystore and exported related X509 certificate with: keytool -export -alias myalias -file cert.cer -keystore my.keystore After I saved cert.cer on client side (C#) and I write this code: X509Certificate2 x509 = new X509Certificate2(); byte[] rawData = ReadFile("mycert.cer"); x509.Import(rawData); RSACryptoServiceProvider rsa = (RSACryptoServiceProvider)x509.PublicKey.Key; byte[] plainbytes = System.Text.Encoding.ASCII.GetBytes("My Secret"); byte[] cipherbytes = rsa.Encrypt(plainbytes, true); String cipherHex = convertToHex(cipherContent); byte[] byteArray = encoding.GetBytes(cipherHex); .... I write this Java code on server side: keyStore = KeyStore.getInstance(KeyStore.getDefaultType()); keyStore.load(new FileInputStream("C:\\my.keystore"), "mypass".toCharArray()); Key key = keyStore.getKey("myalias", "mypass".toCharArray()); if (key instanceof PrivateKey) { Certificate cert = keyStore.getCertificate("myalias"); PublicKey pubKey = cert.getPublicKey(); privKey = (PrivateKey)key; } byte[] toDecodeBytes = new BigInteger(encodeMessageHex, 16).toByteArray(); Cipher decCipher = Cipher.getInstance("RSA"); decCipher.init(Cipher.DECRYPT_MODE, privKey); byte[] decodeMessageBytes = decCipher.doFinal(toDecodeBytes); String decodeMessageString = new String(decodeMessageBytes); I receive this error: javax.crypto.BadPaddingException: Data must start with zero Can you help me, please? Thanks thanks,
