• How does the fstab 'defaults' option work? Is relatime recommended?

  - by hushs

  I know the fstab defaults option means this: rw,suid,dev,exec,auto,nouser,async. But what if I want to add one more option, for example relatime, should I still add defaults too or they are applied anyway? Is it needed to add at least one option? Some examples: 1. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 defaults 0 2 2. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 0 2 3. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 defaults,relatime 0 2 4. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 relatime 0 2 Is the (2) correct(no option at all)? Are the (1) and (2) the same? Are the (3) and (4) the same? Furthermore, I read in the Ubuntu Community Documentation that in Ubuntu 8.04 relatime was used as default for linux native file systems. Is it still true for 12.04? If yes, then why do I see this if I use the mount command: /dev/sda2 on / type ext4 (rw,errors=remount-ro) If no, why not? It isn't recommended to use relatime now? I just wanted to apply it to my non system partitions, it is a good idea? EDIT: I found an other command to list the mounted partitions and their options: cat /proc/mounts This is the result of a partition mounted with the defaults option in fstab: /dev/sdb2 /media/adat ext3 rw,relatime,errors=continue,barrier=1,data=ordered 0 0 This is the output of mount for the same partition: /dev/sdb2 on /media/adat type ext3 (rw) And here is both result if the same partition mounted from Nautilus as a non-root user: /dev/sdb2 /media/adat ext3 rw,nosuid,nodev,relatime,errors=continue,barrier=1,data=ordered 0 0 /dev/sdb2 on /media/adat type ext3 (rw,nosuid,nodev,uhelper=udisks) So it looks like relatime is used if we mount an ext partition in 12.04. So it is unneeded to add it manually. So my problem is broadly solved. But I still can't see why the options that should be in the defaults are not listed even with the cat /proc/mounts. Maybe there is a third and even better method to list the partition mount options :)

• Imperative vs. component based programming [closed]

  - by AlexW

  I've been thinking about how programming and more specifically the teaching of programming is advocated amongst the community (online). Often I've heard that Ruby and RoR is an ideal platform for learning to program. I completely disagree... RoR and Ruby are based on the application of the component based paradigm, which means they are ideal for rapid application development. This is much like the MVC model in PHP and ASP.NET But, learning a proper imperative language like Java or C/C++ (or even Perl and PHP) is the only way for a new programmer to explore logic itself, and not get too bogged down in architectural concerns like the need for separation of concerns, and the preference for components. Maybe it's a personal preference thing. I rather think that the most interesting aspects to programming are the procedural bits of code I write that actually do stuff rather than the project planning, and modelling that comes about from fully object oriented engineering or simply using the MVC model. I know this may sound confused to some of you. I feel strongly though that the best way for programming to be taught is through imperative and procedural methods. Architectural (component) methods come later, if at all. After all, none of the amazing algorithms that exist were based on OOP practice! It's all procedural code when it comes to the 'magic'. OOP is useful in creating products and utilities. Algorithms are what makes things happen, and move data around, and so imperative (and/or procedural) code are what matters most. When I see programmers recommending Ruby on Rails to newbie developers, I think it's just so wrong. Just because you write less code with Ruby does not make it easier to do! It's the opposite... you have to know loads more to appreciate its succinct nature. New coders who really want to understand the nuts and bolts of coding need to go away and figure out writing methods/functions (i.e. imperative programming) and working in procedural style, in order to grasp the fundamentals, first, before looking into architectural ways of working. So, my question is: should Ruby ever be recommended as a first language? I think no (obviously)... what arguments are there for it?

• Finding Tools Guidance in OUM

  - by user716869

  OUM is not tool – specific. However, it does include tool guidance.  Tool guidance in OUM includes: a mention of a tool that could be used to complete a specific task(s) templates created with a specific tool example work products in a specific tool links to tool resources Tool Supplemental Guides So how do you find all this helpful tool information? Start at the lowest level first – the Task Overview.  Even though the task overviews are written tool-agnostic, they sometimes mention suggestions, or examples of a tool that might be used to complete the task.  More specific tool information can be found in the Task Overview, Templates and Tools section.  In some cases, the tool used to create the template (for example, Microsoft Word, Powerpoint, Project and Visio) is useful. The Templates and Tools section also provides more specific tool guidance, such as links to: White Papers Viewlets Example Work Products Additional Resources Tool Supplemental Guides If you’re more interested in seeing what tools might be helpful in general for your project or to see if there is any tool guidance for a specific tool that your project is committed to using, go to the Supplemental Guidance page in OUM.  This page is available from the Method Navigation pull down located in the header of almost every OUM page. When you open the Supplemental Guidance page, the first thing you see is a table index of everything that is included on the page.  At the top of the right column are all the Tool Supplemental Guides available in OUM.  Use the index to navigate to any of the guides. Next in the right column is Discipline/Industry/View Resources and Samples.  Use the index to navigate to any of these topics and see what’s available and more specifically, if there is any tool guidance available.  For example, if you navigate to the Cloud Resources, you will find a link to the IT Strategies from Oracle page that provides information for Cloud Practitioner Guides, Cloud Reference Architectures and Cloud White Papers, including the Cloud Candidate Selection Tool and Cloud Computing Maturity Model. The section for Method Tool and Technique Cross References can take you to the Task to Tool Cross Reference.  This page provides a task listing with possible helpful tools and links to more information regarding the tools.  By no means is this tool guidance all inclusive.  You can use other tools not mentioned in OUM to complete an OUM task. The Method Tool and Technique Cross References can also take you to the various Technique pages (Index and Cross References).  While techniques are not necessarily “tools,” they can certainly provide valuable assistance in completing tasks. In the Other Resources section of the Supplemental Guidance page, you find links to the viewlets and white papers that are included within OUM.

• Getting a SecurityToken from a RequestSecurityTokenResponse in WIF

  - by Shawn Cicoria

  When you’re working with WIF and WSTrustChannelFactory when you call the Issue operation, you can also request that a RequestSecurityTokenResponse as an out parameter. However, what can you do with that object?  Well, you could keep it around and use it for subsequent calls with the extension method CreateChannelWithIssuedToken – or can you? public static T CreateChannelWithIssuedToken<T>(this ChannelFactory<T> factory, SecurityToken issuedToken);   As you can see from the method signature it takes a SecurityToken – but that’s not present on the RequestSecurityTokenResponse class. However, you can through a little magic get a GenericXmlSecurityToken by means of the following set of extension methods below – just call rstr.GetSecurityTokenFromResponse() – and you’ll get a GenericXmlSecurityToken as a return. public static class TokenHelper { /// <summary> /// Takes a RequestSecurityTokenResponse, pulls out the GenericXmlSecurityToken usable for further WS-Trust calls /// </summary> /// <param name="rstr"></param> /// <returns></returns> public static GenericXmlSecurityToken GetSecurityTokenFromResponse(this RequestSecurityTokenResponse rstr) { var lifeTime = rstr.Lifetime; var appliesTo = rstr.AppliesTo.Uri; var tokenXml = rstr.GetSerializedTokenFromResponse(); var token = GetTokenFromSerializedToken(tokenXml, appliesTo, lifeTime); return token; } /// <summary> /// Provides a token as an XML string. /// </summary> /// <param name="rstr"></param> /// <returns></returns> public static string GetSerializedTokenFromResponse(this RequestSecurityTokenResponse rstr) { var serializedRst = new WSFederationSerializer().GetResponseAsString(rstr, new WSTrustSerializationContext()); return serializedRst; } /// <summary> /// Turns the XML representation of the token back into a GenericXmlSecurityToken. /// </summary> /// <param name="tokenAsXmlString"></param> /// <param name="appliesTo"></param> /// <param name="lifetime"></param> /// <returns></returns> public static GenericXmlSecurityToken GetTokenFromSerializedToken(this string tokenAsXmlString, Uri appliesTo, Lifetime lifetime) { RequestSecurityTokenResponse rstr2 = new WSFederationSerializer().CreateResponse( new SignInResponseMessage(appliesTo, tokenAsXmlString), new WSTrustSerializationContext()); return new GenericXmlSecurityToken( rstr2.RequestedSecurityToken.SecurityTokenXml, new BinarySecretSecurityToken( rstr2.RequestedProofToken.ProtectedKey.GetKeyBytes()), lifetime.Created.HasValue ? lifetime.Created.Value : DateTime.MinValue, lifetime.Expires.HasValue ? lifetime.Expires.Value : DateTime.MaxValue, rstr2.RequestedAttachedReference, rstr2.RequestedUnattachedReference, null); } }

• MOSSt 2010 Hosting :: Dialog Platform in SharePoint 2010 & How to Open the Edit Form Dialog for List Item

  - by mbridge

  One of the New User Interface Platforms in SharePoint 2010 is ‘The Dialog Platform’ A dialog is essentially a <div> which gets visible on demand and renders the HTML using a background overlay creating a modal dialog like user experience. We can show an existing div from within the page or a different page using a URL inside the dialogs. When we pass the URL to the dialog it looks for the Querystring parameter “IsDlg=1”. If this parameters exists than it would dynamically load the "/_layouts/styles/dlgframe.css” file. This file overrides the “s4-notdlg” class items as “display:none”, which means that all items with this class would not get displayed in Dialog Mode.  So if we go to the v4.master page we can see that this class is used by the Ribbon control to hide the ribbon when in dialog mode: How to open the Edit Form Dialog for List Item: In SharePoint 2010 The URL for opening the Edit Form of any list item looks like something like this : http://intranet.contoso.com/<SiteName>/Lists/<ListName>/EditForm.aspx?ID=1&IsDlg=1 ID is the list item row identifier and as discussed above the IsDlg is for the dialog mode. Now to open a dialog we need to use the SP.UI.ModalDialog.showModalDialog method from the ECMAScript Client Object model and pass in the url of the page, width & height of the dialog and also a callback function in case we want some code to run after the dialog is closed. <script type="text/javascript">          //Handle the DialogCallback callback               function DialogCallback(dialogResult, returnValue){               }             //Open the Dialog           function OpenEditDialog(id){             var options = { url:&quot;http://intranet.contoso.com/<SiteName>/Lists/<ListName>/EditForm.aspx?ID=&quot; + id + &quot;&amp;IsDlg=1&quot;,              width: 700,              height: 700,              dialogReturnValueCallback: DialogCallback              };             SP.UI.ModalDialog.showModalDialog(options);           } </script> The .js files for the ECMAScript Object Model (SP.js, SP.Core.js, SP.Ribbon.js, and SP.Runtime.js ) are installed in the %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\LAYOUTS directory. Here is a good MSDN link explaining the Client Object Model Distribution and Deployment options available in SharePoint 2010 and this is the lowest costSharePoint 2010 Provider.

• Windows Phone 7, taking the mobile out of mobile

  - by markritchie

  I’ll start off this blog entry with a little background which is necessary for you to understand my situation. I moved from to the UK to Germany about three years ago and while I can converse in German, English is still very much my first language and the language I want my content delivered in. I happily purchased a HTC HD7 when WP7 was released here in Germany thinking foolishly that Microsoft really would get internationalization and localization as it’s at the heart of their business and developer products. Overall I’m very happy with my WP7, the camera sucks but that’s more HTC’s fault that Microsoft, but other than that it’s a very promising platform. My problems started when I purchased my first app. Initially everything appeared to be fine and things were as smooth as things had been with my previous free applications, however about a month after I received an email from Zune informing me that the credit card that they had registered against my account had expired. No problem I foolishly thought; I’ll simply add a new one. I don’t want to bore you with the details of what I’ve been through other than to take the low-lights: trying numerous websites, posts on Microsoft Answers and a tweet to Microsoft Support all to no avail. Today somebody suggested that I call the Xbox support line in the UK as they had solved their billing problems this way. So I called up the Xbox support line since I hadn’t resolved the problem using the Zune portal to resolve my problem with my WP7 (anybody else thinks Microsoft might need some consolidation here). After being on the phone with a very friendly representative in Ireland I was informed that because my British credit card has a billing address in Germany they are unable to accept it as a credit card. Because my Live ID and Zune Tag are registered in the UK they cannot take my card. Their solution is that I have to create a new Zune Tag that has its locale in Germany and then associate it with my phone. Now, first thing I go to register for a Zune Tag with a German locale it very kindly switches into German for me, nothing quite like reading a EULA in a language you’re not fluent in. I’ve no idea how this will affect the apps that are available to me in the app store, and I’m pretty sure it means that all my Xbox live achievements will become history. And what if I was to move to say France at some point do I have to go through all this again? At the end of the day I’m trying to set something up so I can give them my money and they’re making it VERY difficult for me. Could you imagine walking into a book store when you were on holiday and being told by the clerk that they couldn’t take your credit card because you came from another country?

• Threads slowing down application and not working properly

  - by Belgin

  I'm making a software renderer which does per-polygon rasterization using a floating point digital differential analyzer algorithm. My idea was to create two threads for rasterization and have them work like so: one thread draws each even scanline in a polygon and the other thread draws each odd scanline, and they both start working at the same time, but the main application waits for both of them to finish and then pauses them before continuing with other computations. As this is the first time I'm making a threaded application, I'm not sure if the following method for thread synchronization is correct: First of all, I use two global variables to control the two threads, if a global variable is set to 1, that means the thread can start working, otherwise it must not work. This is checked by the thread running an infinite loop and if it detects that the global variable has changed its value, it does its job and then sets the variable back to 0 again. The main program also uses an empty while to check when both variables become 0 after setting them to 1. Second, each thread is assigned a global structure which contains information about the triangle that is about to be rasterized. The structures are filled in by the main program before setting the global variables to 1. My dilemma is that, while this process works under some conditions, it slows down the program considerably, and also it fails to run properly when compiled for Release in Visual Studio, or when compiled with any sort of -O optimization with gcc (i.e. nothing on screen, even SEGFAULTs). The program isn't much faster by default without threads, which you can see for yourself by commenting out the #define THREADS directive, but if I apply optimizations, it becomes much faster (especially with gcc -Ofast -march=native). N.B. It might not compile with gcc because of fscanf_s calls, but you can replace those with the usual fscanf, if you wish to use gcc. Because there is a lot of code, too much for here or pastebin, I created a git repository where you can view it. My questions are: Why does adding these two threads slow down my application? Why doesn't it work when compiling for Release or with optimizations? Can I speed up the application with threads? If so, how? Thanks in advance.

• Redesigning an Information System - Part 1

  - by dbradley

  Through the next few weeks or months I'd like to run a small series of articles sharing my experiences from the largest of the project I've worked on and explore some of the real-world problems I've come across and how we went about solving them. I'm afraid I can't give too many specifics on the project right now as it's not yet complete so you'll have to forgive me for being a little abstract in places! To start with I'm going to run through a little of the background of the problem and the motivations to re-design from scratch. Then I'll work through the approaches taken to understanding the requirements, designing, implementing, testing and migrating to the new system. Motivations for Re-designing a Large Information System The system is one that's been in place for a number of years and was originally designed to do a significantly different one to what it's now being used for. This is mainly due to the product maturing as well as client requirements changing. As with most information systems this one can be defined in four main areas of functionality: Input – adding information to the system Storage – persisting information in an efficient, searchable structure Output – delivering the information to the client Control – management of the process There can be a variety of reasons to re-design an existing system; a few of our own turned out to be factors such as: Overall system reliability System response time Failure isolation and recovery Maintainability of code and information General extensibility to solve future problem Separation of business and product concerns New or improved features The factor that started the thought process was the desire to improve the way in which information was entered into the system. However, this alone was not the entire reason for deciding to redesign. Business Drivers Typically all software engineers would always prefer to do a project from scratch themselves. It generally means you don't have to deal with problems created by predecessors and you can create your own absolutely perfect solution. However, the reality of working within a business is that the bottom line comes down to return on investment. For a medium sized business such as mine there must be actual value able to be delivered within a reasonable timeframe for any work to be started. As a result, any long term project will generally take a lot of effort and consideration to be approved by those in charge and therefore it might be better to break down the project into more manageable chunks which allow more frequent deliverables and also value within a shorter timeframe. As the only thing of concern was the methods for inputting information, this is where we started with requirements gathering and design. However knowing that there might be more to the problem and not limiting your design decisions before the requirements is key to finding the best solutions.

• What's a good way to get an IT internship? [closed]

  - by user1419715

  I'm a second year CS student who's worked really hard to build and expand my skills. I've spent the past week now trying to find a place to volunteer (i.e. work for FREE) so I can get a little bit of in-the-door experience with web development. I have a portfolio with several decent projects, a handful of languages and other hard/soft skills that employers constantly say they're clamoring for. I can't even get people to take my calls. This is me offering to work for them for FREE, remember. I'm in a reputable program at a respected school, get decent grades and...yeah, I've worked really hard to be presentable. On the rare occassions I actually get to speak to somebody at a design firm they hedge and do everything they can to get me off the phone. Nobody's ever expressed even the slightest interest in taking me on. The answer to the experience problem is supposed to be "you need to spend a year or two building up a big portfolio of projects on your own" so that employers will be impressed. I've done that. Websites, standalone apps, etc.. Nobody will even look at my resume, though. Question: Why does there seem to be so little interest in taking on upaid interns in the world of IT? Update: Sorry you all think I'm too aggressive or angry. It wasn't my intent to be a jerk to people while asking them for their opinions. That said, how would you feel if employer after employer turned you down cold when you offered yourself to them without asking for remuneration? One can't even get an unpaid job in this economy now, it seems. How am I going about my search? I find web firms in my area and contact them via email with a brief sales pitch of myself and a resume attached. Then a couple of days later I follow up with a phone contact. Nobody--anywhere--is advertising for interns of any kind. If there were I'm sure there'd be about 500 resumes per position, even unpaid. I've had good experiences in the past with cold-calling firms for actual paid jobs in other industries (hiring is a pain in the ass process and a call like this can show initiative while reducing a busy employer's need to do all the hiring overhead work), so I thought volunteering would work at least as well. My skills are pretty good for a CS student and include the usual suspects: HTML/CSS/Javascript, Python, Java, C, C#/.Net etc etc. I made a point on my resume to tie each ability claim to a project as well. Oh, and regarding the "working for free still costs the employer money" argument: that's an excellent point I hadn't though of. But it means...what? I have to pay the employer for the privilege of working there now?

• Misused mke2fs and cannot boot into system

  - by surlogics

  I installed Ubuntu with WUBI in Windows 7 64bit, and I had installed Mandriva 2011 with a disk. I tried to learn Linux with Ubuntu and misused mke2fs; after I reboot my computer, Windows 7 and Ubuntu has crashed.

• Normal Redundancy (Double Mirroring) Option Available

  - by TammyBednar

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif";} The Oracle Database Appliance 2.4 Patch was released last week and provides you an option of ASM normal redundancy (double mirroring) during the initial deployment of the Database Appliance. The default deployment of the Oracle Database Appliance is high redundancy for the +DATA and +RECO disk groups. While there is 12TB of raw shared storage available, the Database Backup Location and Disk Group Redundancy govern how much usable storage is presented after the initial deployment is completed. The Database Backup Location options are Local or External. When the Local Backup Option is selected, this means that 60% of the available shared storage will be allocated for the Fast Recovery Area that contains database backups and archive logs. The External Backup Option will allocate 20% of the available shared storage to the Fast Recovery Area. So, let’s look at an example of High Redundancy and External Backups. Disk Group Redundancy – High --> Triple Mirroring to provide ~4TB of available storage Database Backup Location – External --> 20% of available shared storage allocated to +RECO +DATA = 3.2TB of usable storage, +RECO = 0.8TB of usable storage What about Normal Redundancy with External Backups? Disk Group Redundancy – Normal --> Double Mirroring to provide ~6TB of available storage Database Backup Location – External --> 20% of available shared storage allocated to +RECO +DATA = 4.8TB of usable storage, +RECO = 1.2TB of usable storage As a best practice, we would recommend using Normal Redundancy for your test and/or development Oracle Database Appliances and High Redundancy for production.

• Need Help with partitions and such Dual Booting 13.10 w/ windows 7

  - by Aymax

  so I've spent the past couple days freaking out about this and looking for answers, and I decided to resort to asking on forums. probably should have before I wasted 2 entire days. so I am trying to DUAL-INSTALL Ubuntu 13.10 with my x64 Windows 7 home premium computer. I have 6 gb of ram, 1TB hard drive, and a 3.3GHZ dual core processer (just in case it matters). I've managed to figure some things out. I've burned the ubuntu files onto a DVD, and I have been able to successfully run it off the disk. I also shrunk my Windows partition by 120Gb and partitioned that for Ubuntu (all using the windows Disk Manager). Problems: When I turn my computer on with the DVD in the tray, the computer cant find windows. it flashes a screen real quick that says something about not being able to find an operating system, and then goes to "grub" and asks what i want to do with Ubuntu. this scares me, because I don't know if that means that I will not be able to boot windows if I install Ubuntu. The Ubuntu 13.10 installer does not detect my Windows operating system. I only have the options to Erase everything on my drive, or "something else." I choose that, which brings me to 3 I don't understand the partition table. I have no idea which drive im selecting to install stuff on, much less which one to select. I tried to tell by the amount of memory partitioned off, but none of the numbers seem to be accurate. Plus, all the names are dev/sda(#). I know Ubuntu knows the name of my partition, because on the sidebars it shows the names of the different drives, including the partition I made; so why don't they use the names? I have no idea what I'm going to be erasing. I've read that I should know which is which by the file system type, but they are all NTFS, including the one I made. my only other option was FAT, none for EXT2 or any of that like people said to do. My main concerns are that of accidentally erasing windows or not being able to access windows. any feasible solution is helpful, weather it helps me with the install or to make Ubuntu see windows. I realize this question has been asked much, but i have found no feasible answers so far. I am relatively new to this, and have never installed an operating system before, so I do not know most of the jargon. please keep it relatively simple, please. I am not a programmer. Thanks.

• Is the Observer pattern adequate for this kind of scenario?

  - by Omega

  I'm creating a simple game development framework with Ruby. There is a node system. A node is a game entity, and it has position. It can have children nodes (and one parent node). Children are always drawn relatively to their parent. Nodes have a @position field. Anyone can modify it. When such position is modified, the node must update its children accordingly to properly draw them relatively to it. @position contains a Point instance (a class with x and y properties, plus some other useful methods). I need to know when a node's @position's state changes, so I can tell the node to update its children. This is easy if the programmer does something like this: @node.position = Point.new(300,300) Because it is equivalent to calling this: # Code in the Node class def position=(newValue) @position = newValue update_my_children # <--- I know that the position changed end But, I'm lost when this happens: @node.position.x = 300 The only one that knows that the position changed is the Point instance stored in the @position property of the node. But I need the node to be notified! It was at this point that I considered the Observer pattern. Basically, Point is now observable. When a node's position property is given a new Point instance (through the assignment operator), it will stop observing the previous Point it had (if any), and start observing the new one. When a Point instance gets a state change, all observers (the node owning it) will be notified, so now my node can update its children when the position changes. A problem is when this happens: @someNode.position = @anotherNode.position This means that two nodes are observing the same point. If I change one of the node's position, the other would change as well. To fix this, when a position is assigned, I plan to create a new Point instance, copy the passed argument's x and y, and store my newly created point instead of storing the passed one. Another problem I fear is this: somePoint = @node.position somePoint.x = 500 This would, technically, modify @node's position. I'm not sure if anyone would be expecting that behavior. I'm under the impression that people see Point as some kind of primitive rather than an actual object. Is this approach even reasonable? Reasons I'm feeling skeptical: I've heard that the Observer pattern should be used with, well, many observers. Technically, in this scenario there is only one observer at a time. When assigning a node's position as another's (@someNode.position = @anotherNode.position), where I create a whole new instance rather than storing the passed point, it feels hackish, or even inefficient.

• Should I use my own public API on my site (via JS)?

  - by newboyhun

  First of all, this question is far more different other 'public api questions' like this: Should a website use its own public API?, second, sorry for my English. You can find the question summarized at the bottom of this question. What I want to achieve is a big website with a public api, so who like programming (like me) and likes my website, can replicate my website's data with a much better approach (of course with some restrictions). Almost everything could be used by the public API. Because of this, I was thinking about making the whole website AJAX driven. There would be parts of the API which would be limited only to my website (domain), like login, registering. There would be only an INTERFACE on the client side, which would use the public and private API to make this interface working. The website would be ONLY CLIENT SIDE, well, I mean, the website would only use AJAX to use the api. How do I imagine this? The website would be like a mobile application, the application only sending a request to a webserver, which returns a json, the application parses it, and uses it to advance in the application. (e.g.: login) My thoughts: Pros: The whole website is built up by javascript, this means I don't need to transfer the html to the client, saving bandwidth. (I hope so) Anyone can use up the data of my website to make their own cool things. (Is this a con or pro? O_O) The public API is always in use, so I can see if there are any error. Cons: Without Javascript the website is unusable. The bad guys easily can load the server with requesting too much data (like Request Per Second 10000), but this can be countered via limiting this with some PHP code and logging. Probably much more work So the question in some words is: Should I build my website around my own api? Is it good to work only on the client side? Is this good for a big website? (e.x.: facebook, yeah facebook is a different story, but could it run with an 'architecture' like this?)

• What is the right way to group this project into classes?

  - by sigil

  I originally asked this on SO, where it was closed and recommended that I ask it here instead. I'm trying to figure out how to group all the functions necessary for my project into classes. The goal of the project is to execute the following process: Get the user's FTP credentials (username & password). Check to make sure the credentials establish a valid connection to the FTP server. Query several Sharepoint lists and join the results of those queries to create a list of items that need to have action taken on them. Each item in the list has a folder. For each item: Zip the contents of the folder. Upload the folder to the FTP server using SFTP Update the item's Sharepoint data. Email the user an Excel report showing, e.g., Items without folder paths Items that failed to zip or upload Steps 2-5 are performed on a periodic basis; if step 2 returns an invalid connection, the user is alerted and the process returns to step 1. If at any point the user presses a certain key, the process terminates. I've defined the following set of classes, each of which is in its own .cs file: SFTP: file transfer processes DataHandler: Sharepoint data retrieval/querying/updating processes. Also makes and uploads the zip files. Exceptions: Not just one class, this is the .cs file where I have all of my exception classes. Report: Builds and sends the report. Program: The main class for running the program. I recognize that the DataHandler class is a god object, but I don't have a good idea of how to refactor it. I feel like it should be more fine-grained than just breaking it into Sharepoint, Zip, and Upload, but maybe that's it. Also, I haven't yet worked out how to combine the periodic behavior with the "wait for user input at any point in the process" part; I think that involves threads, which means other classes to manage the threads... I'm not that well-versed in design patterns, but is there one that fits this project well? If this is too big of a topic to neatly explain in an SO answer, I'll also accept a link to a good tutorial on what I'm trying to do here.

• How should I refactor switch statements like this (Switching on type) to be more OO?

  - by Taytay

  I'm seeing some code like this in our code base, and want to refactor it: (Typescript psuedocode follows): class EntityManager{ private findEntityForServerObject(entityType:string, serverObject:any):IEntity { var existingEntity:IEntity = null; switch(entityType) { case Types.UserSetting: existingEntity = this.getUserSettingByUserIdAndSettingName(serverObject.user_id, serverObject.setting_name); break; case Types.Bar: existingEntity = this.getBarByUserIdAndId(serverObject.user_id, serverObject.id); break; //Lots more case statements here... } return existingEntity; } } The downsides of switching on type are self-explanatory. Normally, when switching behavior based on type, I try to push the behavior into subclasses so that I can reduce this to a single method call, and let polymorphism take care of the rest. However, the following two things are giving me pause: 1) I don't want to couple the serverObject with the class that is storing all of these objects. It doesn't know where to look for entities of a certain type. And unfortunately, the identity of a type of ServerObject varies with the type of ServerObject. (So sometimes it's just an ID, other times it's a combination of an id and a uniquely identifying string, etc). And this behavior doesn't belong down there on those subclasses. It is the responsibility of the EntityManager and its delegates. 2) In this case, I can't modify the ServerObject classes since they're plain old data objects. It should be mentioned that I've got other instances of the above method that take a parameter like "IEntity" and proceed to do almost the same thing (but slightly modify the name of the methods they're calling to get the identity of the entity). So, we might have: case Types.Bar: existingEntity = this.getBarByUserIdAndId(entity.getUserId(), entity.getId()); break; So in that case, I can change the entity interface and subclasses, but this isn't behavior that belongs in that class. So, I think that points me to some sort of map. So eventually I will call: private findEntityForServerObject(entityType:string, serverObject:any):IEntity { return aMapOfSomeSort[entityType].findByServerObject(serverObject); } private findEntityForEntity(someEntity:IEntity):IEntity { return aMapOfSomeSort[someEntity.entityType].findByEntity(someEntity); } Which means I need to register some sort of strategy classes/functions at runtime with this map. And again, I darn well better remember to register one for each my my types, or I'll get a runtime exception. Is there a better way to refactor this? I feel like I'm missing something really obvious here.

• Down to the Wire - Yet More Solaris Things to See at OpenWorld (and JavaOne!)

  - by Larry Wake

  San Francisco is bracing for the annual invasion. The airport's jammed, the tweets are flying, and the numbers are crazy: more than 50,000 attendees and 2,500+ sessions, taking over Moscone Convention Center, two streets, Union Square, and seemingly every hotel in town (98,000 hotel room nights). So yeah, it's busy. And it's not just OpenWorld--we've also got JavaOne, MySQL Connect, and four other sub-events going on as well. Speaking of JavaOne, you can find Solaris-related activity there, too -- I've highlighted one hands-on lab below. Here's a last pre-event roundup of activities for consideration; enjoy the show(s)! (Remember, Schedule Builder is your friend; use it with the session numbers below to register.) Monday, October 1st: 3:15 PM - General Session: Accelerate Your Business with the Oracle Hardware Advantage(GEN9691, Moscone North Hall D) John Fowler, head of Oracle's Systems organization, will talk about Oracle hardware technology and how it's co-engineered with other key technologies, including Oracle Solaris. Tuesday, October 2nd: 10:15 AM - Building an IaaS Platform with SPARC, Oracle Solaris 11, and Oracle VM Server for SPARC(CON4431, Moscone South 270)Get the birds-eye lowdown (whatever that means) on how U.S. Cellular  built its Infrastructure as a Service (IaaS) cloud delivery platform with Oracle’s SPARC T4 servers, Oracle Solaris 11, Oracle Solaris Cluster 4, and Oracle VM Server for SPARC. The session covers the high-level design, business case made, implementation details, and lessons learned. 11:45 AM - Oracle Solaris 11 Panel: Insights and Directions from Oracle Solaris Core Engineering(CON8790, Moscone South 252) This has been one of the livelier Solaris-related sessions in years past (and I'm not saying that just because I get to moderate it this year). A panel of core engineers responsible for a wide range of key Solaris technologies will talk about some of the interesting work they've been doing -- but mostly we keep time open for the panel to take questions from attendees, because that's the fun part. Wednesday, October 3rd: 10:00 AM - Tracing Your Java Application Tuning on Oracle Solaris with DTrace(HOL10214, Hilton San Francisco, Franciscan A/B/C/D) This JavaOne hands-on lab will show how to use the DTrace framework to dynamically trace your Java applications on Oracle Solaris and uncover new tuning opportunities.

• JEditorPane Code Completion (Part 2)

  - by Geertjan

  Figured it out! No need to create a fake Java file, unlike what I said in part 1, no need to depend on all the Java Editor modules, if you use DialogBinding.bindComponentToDocument, instead of DialogBinding.bindComponentToFile: public final class CountryEditorTopComponent extends TopComponent {     public CountryEditorTopComponent() {         initComponents();         setName(Bundle.CTL_CountryEditorTopComponent());         setToolTipText(Bundle.HINT_CountryEditorTopComponent());         EditorKit kit = CloneableEditorSupport.getEditorKit("text/plain");         jEditorPane1.setEditorKit(kit);         DialogBinding.bindComponentToDocument(jEditorPane1.getDocument(), 0, 0, jEditorPane1);         jEditorPane1.setText("Egypt");     } The above requires a dependency on Editor Library 2, which is where DialogBinding is found. Aside from that, you need all the dependencies required by the Code Completion API, as described in the Code Completion tutorial on the NetBeans Platform Learning Trail. Once you've done that, go to the Project Properties dialog of the application and then in the "ide" cluster, include "Plain Editor" and "Plain Editor Library". I.e., two additional JARs only. These two are needed because you've set the MIME type to "text/plain", which is needed because DialogBinding expects the JEditorPane to have a MIME type. And now everything works. Press Ctrl-Space in your JEditorPane and, because your CompletionProvider is registered in "text/x-dialog-binding" (via the annotation on CompletionProvider), your completion items are displayed. (The only MIME type for binding a document to a component, by default, is "text/x-dialog-binding", which means the next step is for someone to figure out how to support multiple different of such MIME types, since each JEditorPane in your application is likely to require its own specific code completion support.) I think this is a really workable solution for real scenarios where JEditorPanes in NetBeans Platform applications require code completion.

• Is it good practice to keep 2 related tables (using auto_increment PK) to have the same Max of auto_increment ID when table1 got modified?

  - by Tum

  This question is about good design practice in programming. Let see this example, we have 2 interrelated tables: Table1 textID - text 1 - love.. 2 - men... ... Table2 rID - textID 1 - 1 2 - 2 ... Note: In Table1: textID is auto_increment primary key In Table2: rID is auto_increment primary key & textID is foreign key The relationship is that 1 rID will have 1 and only 1 textID but 1 textID can have a few rID. So, when table1 got modification then table2 should be updated accordingly. Ok, here is a fictitious example. You build a very complicated system. When you modify 1 record in table1, you need to keep track of the related record in table2. To keep track, you can do like this: Option 1: When you modify a record in table1, you will try to modify a related record in table 2. This could be quite hard in term of programming expecially for a very very complicated system. Option 2: instead of modifying a related record in table2, you decided to delete old record in table 2 & insert new one. This is easier for you to program. For example, suppose you are using option2, then when you modify record 1,2,3,....,100 in table1, the table2 will look like this: Table2 rID - textID 101 - 1 102 - 2 ... 200 - 100 This means the Max of auto_increment IDs in table1 is still the same (100) but the Max of auto_increment IDs in table2 already reached 200. what if the user modify many times? if they do then the table2 may run out of records? we can use BigInt but that make the app run slower? Note: If you spend time to program to modify records in table2 when table1 got modified then it will be very hard & thus it will be error prone. But if you just clear the old record & insert new records into table2 then it is much easy to program & thus your program is simpler & less error prone. So, is it good practice to keep 2 related tables (using auto_increment PK) to have the same Max of auto_increment ID when table1 got modified?

• What add-in/workbench framework is the best .NET alternative to Eclipse RCP?

  - by Winston Fassett

  I'm looking for a plugin-based application framework that is comparable to the Eclipse Plugin Framework, which to my simple mind consists of: a core plugin management framework (Equinox / OSGI), which provides the ability to declare extension endpoints and then discover and load plugins that service those endpoints. (this is different than Dependency Injection, but admittedly the difference is subtle - configuration is highly de-centralized, there are versioning concerns, it might involve an online plugin repository, and most importantly to me, it should be easy for the user to add plugins without needing to know anything about the underlying architecture / config files) many layers of plugins that provide a basic workbench shell with concurrency support, commands, preference sheets, menus, toolbars, key bindings, etc. That is just scratching the surface of the RCP, which itself is meant to serve as the foundation of your application, which you build by writing / assembling even more plugins. Here's what I've gleaned from the internet in the past couple of days... As far as I can tell, there is nothing in the .NET world that remotely approaches the robustness and maturity of the Eclipse RCP for Java but there are several contenders that do either #1 or #2 pretty well. (I should also mention that I have not made a final decision on WinForms vs WPF, so I'm also trying to understand the level of UI coupling in any candidate framework. I'm also wondering about platform coupling and source code licensing) I must say that the open-source stuff is generally less-documented but easier to understand, while the MS stuff typically has more documentation but is less accessible, so that with many of the MS technologies, I'm left wondering what they actually do, in a practical sense. These are the libraries I have found: SharpDevelop The first thing I looked at was SharpDevelop, which does both #1 and also #2 in a basic way (no insult to SharpDevelop, which is admirable - I just mean more basic than Eclipse RCP). However, SharpDevelop is an application more than a framework, and there are basic assumptions and limitations there (i.e. being somewhat coupled to WinForms). Still, there are some articles on CodeProject explaining how to use it as the foundation for an application. System.Addins It appears that System.Addins is meant to provide a robust add-in loading framework, with some sophisticated options for loading assemblies with varying levels of trusts and even running the out of process. It appears to be primarily code-based, and pretty code-heavy, with lots of assemblies that serve to insulate against versioning issues., using Guidance Automation to generate a good deal of code. So far I haven't found many System.AddIns articles that illustrate how it could be used to build something like an Eclipse RCP, and many people seem to be wringing their hands about its complexity. Mono.Addins It appears that Mono.Addins was influenced by System.Addins, SharpDevelop, and MonoDevelop. It seems to provide the basics from System.Addins, with less sophisticated options for plugin loading, but more simplicity, with attribute-based registration, XML manifests, and the infrastructure for online plugin repositories. It has a pretty good FAQ and documentation, as well as a fairly robust set of examples that really help paint a picture of how to develop an architecture like that of SharpDevelop or Eclipse. The examples use GTK for UI, but the framework itself is not coupled to GTK. So it appears to do #1 (add-in loading) pretty well and points the way to #2 (workbench framework). It appears that Mono.Addins was derived from MonoDevelop, but I haven't actually looked at whether MonoDevelop provides a good core workbench framework. Managed Extensibility Framework This is what everyone's talking about at the moment, and it's slowly getting clearer what it does, but I'm still pretty fuzzy, even after reading several posts on SO. The official word is that it "can live side-by-side" with System.Addins. However, it doesn't reference it and it appears to reproduce some of its functionality. It seems to me, then, that it is a simpler, more accessible alternative to System.Addins. It appears to be more like Mono.Addins in that it provides attribute-based wiring. It provides "catalogs" that can be attribute-based or directory-based. It does not seem to provide any XML or manifest-based wiring. So far I haven't found much documentation and the examples seem to be kind of "magical" and more reminiscent of attribute-based DI, despite the clarifications that MEF is not a DI container. Its license just got opened up, but it does reference WindowsBase -- not sure if that means it's coupled to Windows. Acropolis I'm not sure what this is. Is it MEF, or something that is still coming? Composite Application Blocks There are WPF and Winforms Composite Application blocks that seem to provide much more of a workbench framework. I have very little experience with these but they appear to rely on Guidance Automation quite a bit are obviously coupled with the UI layers. There are a few examples of combining MEF with these application blocks. I've done the best I could to answer my own question here, but I'm really only scratching the surface, and I don't have experience with any of these frameworks. Hopefully some of you can add more detail about the frameworks you have experience with. It would be great if we could end up with some sort of comparison matrix.

• Windows Server Backup - Recover only shows the latest backup

  - by Steffen

  We're having quite some trouble at work using Windows Server Backup. We have a HyperV server (Win 2008) running 8 virtual web servers, these are running a variety of OS'es: Win 2003, Win 2008 and a lone Debian. Each virtual server has a separate partition on the physical HyperV server, so e.g. E: is virtual server #1, F: is #2 and so forth. For backup we use Windows Server Backup, or more exactly we use the commandline tool: wbadmin.exe We need to make the backups without stopping the virtual servers, as we cannot afford the downtime (we've got users online both day and night), and Windows Server Backup offers to use the shadow copy provider to archive this. We run wbadmin like this: wbadmin start backup -backuptarget:\\remotebackuplocation\somefolder -include:E: -quiet We run it once per partition, because we've got a script wrapped around that command, for sending us an email about how it went. Each time we run wbadmin it'll delete the Backup xxxx folder it created in last backup, and just create a new. In order to prevent this from happening, we rename the backup xxx folder after each backup is run, before starting the next one. I realize we must rename it back to its original name prior to recovering, and we obviously do this. Now the issue is as follows: Even though we have all the backed up files, and rename whichever backup we want to use, to its original name, we can only see the latest backup in the Windows Server Backup GUI when we select "Recover". This means we can only recover the last partition we backup up, so e.g. E: can never be recovered. In other words we're screwed :-( My question is: Does anyone know how to use Windows Server Backup for a scenario like this ? Or is it simply not possible due to the simplicity of Windows Server Backup ? If it's not possible, could you recommend some backup software for this purpose ? We've already looked at MS' System Center Data Protection Manager, however it's quite expensive and the boss doesn't like that :-/

• How many bits for sequence number using Go-Back-N protocol.

  - by Mike

  Hi Everyone, I'm a regular over at Stack Overflow (Software developer) that is trying to get through a networking course. I got a homework problem I'd like to have a sanity check on. Here is what I got. Q: A 3000-km-long T1 trunk is used to transmit 64-byte frames using Go-Back-N protocol. If the propagation speed is 6 microseconds/km, how many bits should the sequence numbers be? My Answer: For this questions what we need to do is lay the base knowledge. What we are trying to find is the size of the largest sequence number we should us using Go-Back-N. To figure this out we need to figure out how many packets can fit into our link at a time and then subtract one from that number. This will ensure that we never have two packets with the same sequence number at the same time in the link. Length of link: 3,000km Speed: 6 microseconds / km Frame size: 64 bytes T1 transmission speed: 1544kb/s (http://ckp.made-it.com/t1234.html) Propagation time = 6 microseconds / km * 3000 km = 18,000 microseconds (18ms). Convert 1544kb to bytes = 1544 * 1024 = 1581056 bytes Transmission time = 64 bytes / 1581056bytes / second = 0.000040479 seconds (0.4ms) So then if we take the 18ms propagation time and divide it by the 0.4ms transmission time we will see that we are going to be able to stuff ( 18 / 0.4) 45 packets into the link at a time. That means that our sequence number should be 2 ^ 45 bits long! Am I going in the right direction with this? Thanks, Mike

• ADODB DB2 DSN using IBMDADB2 provider

  - by Eli Sand

  I have a very bizarre issue with trying to establish a working connection to an IBM DB2 server from Classic ASP using ADODB. On my development server I am running IIS and have a local instance of DB2 running. When I create a system DSN on this server and try to connect to it with ADODB, I have to specify Provider=IBMDADB2; in my connection along with the DSN name - failure to include the provider and my connection won't work. On my production server(s), I have one running IIS and a second system running an instance of DB2. When I create a system DSN on the production IIS server and try to connect to it with ADODB, I cannot specify the provider, otherwise it throws an uncatchable error in an external module (I assume it's referring to the DB2 module) if I try to do anything past get a connection (oddly, opening the connection itself doesn't throw an error - but if I run a query it does). If I remove the Provider=IBMDADB2; from the connection string (thus I just have DSN=some_name), it works fine. On both systems I can verify through the ODBC connection manager that the DSN's work and can connect to the databases, and on both systems I have made sure to set the correct (only) instance of DB2 as the default. Can anyone tell me why I have to have different connection strings for the development and production servers? I would like to be able to use the same connection string for both environments if at all possible. If that means either specifying a provider for both, or for neither I don't care which - I would just like to know what's going on and how to fix it.

• Installing gitosis and closed port?

  - by Nicolas GUILLAUME

  I'm trying to install gitosis on a Server (hosted by OVH and running Ubuntu server 11.04). I've done it a few times and never had any problems. But this time I have something very wired when I simply try to clone gitosis. [root@ovks-1:~/]#git clone git://eagain.net/gitosis.git Cloning into gitosis... eagain.net[0: 208.78.102.120]: errno=Connection refused fatal: unable to connect a socket (Connection refused) zsh: exit 128 git clone git://eagain.net/gitosis.git Based on my searches it looks like the port 9418 is closed. But I don't understand, a server by definition shouldn't have any closed port and I can't find a way to see if they are. So how can I check is a port is open and how can I open it if closed? Thank you for your help. Requested by WesleyDavid: iptables -L result [root@odeoos-vks-1:~/]#iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I have no idea what it means...
