• Proper Data Structure for Commentable Comments

  - by Wesley

  Been struggling with this on an architectural level. I have an object which can be commented on, let's call it a Post. Every post has a unique ID. Now I want to comment on that Post, and I can use ID as a foreign key, and each PostComment has an ItemID field which correlates to the Post. Since each Post has a unique ID, it is very easy to assign "Top Level" comments. When I comment on a comment however, I feel like I now need a PostCommentComment, which attaches to the ID of the PostComment. Since ID's are assigned sequentially, I can no longer simply use ItemID to differentiate where in the tree the comment is assigned. I.E. both a Post and a Post Comment might have an ID of '5', so my foreign key relationship is invalid. This seems like it could go on infinitely, with PostCommentCommentComment's etc... What's the best way to solve this? Should I have a field in the comment called "IsPostComment" or something of the like to know which collection to attach the ID to? This strikes me as the best solution I've seen so far, but now I feel like I need to make recursive DataBase calls which start to get expensive. Meaning, I get a Post and get all PostComments where ItemID == Post.ID && where IsPostComment == true Then I take that as a collection, gather all the ID's of the PostComments, and do another search where ItemID == PostComment[all].ID && where IsPostComment == false, then repeat infinitely. This means I make a call for every layer, and if I'm calling 100 Posts, I might make 1000 DB calls to get 10 layers of comments each. What is the right way to do this?

• xinet vs iptables for port forwarding performance

  - by jamie.mccrindle

  I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.

• How can I find the program making a harmonica sound?

  - by Josh

  A friend has a Windows XP SP3 machine that plays a harmonica sound for about 5 seconds throughout the day at what seems to be random intervals (every couple hours). My question is how can I find the program making this sound? Is there a Windows API hook for monitoring audio access? I've gone through and checked all the standard Windows sounds in the Control Panel and right now the theme is set to no sounds and I personally checked to make sure none of the events have a sound specified. I also checked the Task Scheduler to make sure there wasn't something scheduled to go off every couple hours. Any ideas on how to go about finding the bugger?

• Rotation of bitmap using a frame by frame animation

  - by pengume

  Hey every one I know this has probably been asked a ton of times but I just wanted to clarify if I am approaching this correctly, since I ran into some problems rotating a bitmap. So basically I have one large bitmap that has four frames drawn on it and I only draw one at a time by looping through the bitmap by increments to animate walking. I can get the bitmap to rotate correctly when it is not moving but once the animation starts it starts to cut off alot of the image and sometimes becomes very fuzzy. I have tried public void draw(Canvas canvas,int pointerX, int pointerY) { Matrix m; if (setRotation){ // canvas.save(); m = new Matrix(); m.reset(); // spriteWidth and spriteHeight are for just the current frame showed m.setTranslate(spriteWidth / 2, spriteHeight / 2); //get and set rotation for ninja based off of joystick m.preRotate((float) GameControls.getRotation()); //create the rotated bitmap flipedSprite = Bitmap.createBitmap(bitmap , 0, 0,bitmap.getWidth(),bitmap.getHeight() , m, true); //set new bitmap to rotated ninja setBitmap(flipedSprite); // canvas.restore(); Log.d("Ninja View", "angle of rotation= " +(float) GameControls.getRotation()); setRotation = false; } And then the Draw Method here // create the destination rectangle for the ninjas current animation frame // pointerX and pointerY are from the joystick moving the ninja around destRect = new Rect(pointerX, pointerY, pointerX + spriteWidth, pointerY + spriteHeight); canvas.drawBitmap(bitmap, getSourceRect(), destRect, null); The animation is four frames long and gets incremented by 66 (the size of one of the frames on the bitmap) for every frame and then back to 0 at the end of the loop.

• Make windows vista file explorer act normally

  - by user25866

  Is there some file I can remove or something I can do to globally ensure that windows visa/xp/etc doesn't do annoying things? Annoying things: 1) Hide the file extension 2) All these "meta" columns I could care less about in "details" view (rating, album, date taken, Assistant's name, Artist, 35mm focal length, City, Other City, etc...). All I want are Name, size, date created, date modified, and file extension. MAYBE file chmod settings. 3) That garbage in the left pane known as "favorite links." (Documents, desktop, photos, music, etc...) 4) Switching between detail view, large icon view, thumbnail view, list view, and tiles when I goto differnt folders, all I want is detail view, with the same columns every time. That's it. I shouldn't have to get third party software to make my file system browseable, but if I need to so be it... Why are all these settings buried away? It feels like I have to apply them onto each folder every time.

• How do you cache web pages with a personalized header using caching reverse proxy such as Squid, Var

  - by Continuation

  Pretty much every page of my website is dynamically generated. However they don't change that frequently (kinda similar to a forum page). So I'd like to cache them using a caching reverse proxy such as Squid, varnish or Nginx. The problem is that for my logged-in users, each of them will see a personalized header saying "Welcome John Doe. Logout" on the upper right corner of the page (just like serverfault). While users who aren't logged in will see a header that says "Login" instead. So basically even though every user will see the same page in general, they all slightly different version due to that personalized header. Is there any way so that I can cache the "main" part of the page and serve it from cache while generate the personalized header dynamically for each individual user? This must be a very common problem. How is it solved in general?

• Strategy for restoring state via URL in web apps

  - by JW01

  This is a question about modern web apps, where a single page is loaded, and all subsequent navigation is done by XHR calls and modifying the DOM. We can use libraries that manipulate the hash string, which let us navigate by URL and support the back/forward buttons. But to use those libraries, we need to be able to move the UI from any one state to any other. Is there a good strategy for moving between UI states, that also allows them to be restored from scratch when you load a new URL? In a complex app, you might have a lot of different states. You don't want to reload the entire UI each time you change states. But you also don't want to require separate methods for moving from every state to each every state. Typically we need to: Restore a state from scratch, when you enter a new URL or hit Reload. Move from one state to another, when you use the Back/Forward buttons. Move from one state to another, when you perform an action within your app (like clicking a link). Move to certain states that shouldn't be added to the history, like ones that appear after form submissions. Move to some states that are built on the previous state, like a drill-down list. When you perform actions within your app, there's the additional question of which comes first: Do you change the URL, listen for the URL change, and change your state in response to it? Or do you change your state, then change the URL, but don't do anything in response? Does anyone have some experience to share on this topic?

• Learning to code first game, few questions on basic game development and 3D

  - by ProgrammerByDay

  I've been programming for a while, and I'm concurrently learning how to make a basic game and slimdx, and wanted to talk to someone to hopefully get a few pointers. I've read that Tetris is the "Hello, world" of game programming, which made sense to me, so I decided to give it a shot. I've been able to code up a basic version in a few hours, which I'm quite happy with, but I had a few questions about 3D programming. Right now I'm using Direct3D to do display the blocks without any textures (just colored squares). I have a data structure (2d array of bytes, where each byte denotes the presence of a block and its color) which is the "game board," and on every render() call I create a new vertex buffer of the existing squares in the game board, and draw those primitives. This feels very inefficient, and I wondering what would be the idiomatic way of doing this in a 3D world, with matrix/rotations/translation operations. I know 3D is overkill for such a project, but I want to learn any 3d concepts that I can while I'm doing it. I understand that what you'd usually want to do is keep the same vertices/vertex buffers but manipulate them with matrices to achieve rotations/translations, etc. To do so, I assume what would happen is I'd have one vertex buffer for the "active" piece, since that'll be constantly rotated and moved, and have one vertex buffer for the frozen pieces on the bottom of the board, which is pretty much stationary, but will need to be changed/recreated when the active piece becomes frozen. Right now I'm just clearing and redrawing on every render call, which seems like the easiest way to do things, although I wonder if there's a more efficient way to deal with changes. Obviously there are a lot of questions I'm asking here, but if you can even just point me a step or two ahead in terms of how I should be thinking, it'd be great. Thanks

• How to optimise Andengine's PathModifer (with singleton or pool)?

  - by Casla

  I am trying to build a game where the character find and follows a new path when a new destination is issued by the player, kinda like how units in RTS games work. This is done on a TMX map and I am using the A Star path finder utilities in Andengine to do this.David helped me on that: How can I change the path a sprite is following in real time? At the moment, every-time a new path is issued, I have to abandon the existing PathModifer and Path instances, and create new ones, and from what I read so far, creating new objects when you could re-use existing ones are a big waste for mobile applications. This is how I coded it at the moment: private void loadPathFound() { if (mAStarPath != null) { modifierPath = new org.andengine.entity.modifier.PathModifier.Path(mAStarPath.getLength()); /* replace the first node in the path as the player's current position */ modifierPath.to(player.convertLocalToSceneCoordinates(12, 31)[Constants.VERTEX_INDEX_X]-12, player.convertLocalToSceneCoordinates(12, 31)[Constants.VERTEX_INDEX_Y]-31); for (int i=1; i<mAStarPath.getLength(); i++) { modifierPath.to(mAStarPath.getX(i)*TILE_WIDTH, mAStarPath.getY(i)*TILE_HEIGHT); /* passing in the duration depended on the length of the path, so that the animation has a constant duration for every step */ player.registerEntityModifier(new PathModifier(modifierPath.getLength()/100, modifierPath, null, mIPathModifierListener)); } } The ideal implementation will be to always have just one object of PathModifer and just reset the destination of the path. But I don't know how you can apply the singleton patther on Andengine's PathModifer, there is no method to reset attribute of the path nor the pathModifer. So without re-write the PathModifer and the Path class, or use reflection, is there any other way to implement singleton PathModifer? Thanks for your help.

• different data with same title and keywords

  - by Junaid Saeed

  here is my scenario i have a website where i redirect my users basing upon the device they were using, lets say a user is visiting from an iPad, i take him directly to the page of iPad wallpapers, the user selects iPad version & i take the user to the gallery of wallpapers where the user can select & download any wallpaper. Every wallpaper is the required resolution, i have my reasons for doing this, now the thing is there are diff. resolution. versions of an image appearing one 5 diff. sections of my website, each having their own view page Now there is only one record in db.table for the image, and basing on the my consistent naming convention of the images, i pick the required image. this means when 5 different pages are generated in 5 categorized sections of the website, due to a shared DB record, the keywords, the titles and every single detail of the 5 pages is same besides the resolution of the image, and the section specific details that the page has and yeah the pages also have different paths like wallpapers.com\ipad-1\cars\Ferrari-dino.html wallpapers.com\ipad-2\cars\Ferrari-dino.html wallpapers.com\ipad-3\cars\Ferrari-dino.html wallpapers.com\ipad-4\cars\Ferrari-dino.html wallpapers.com\ipad-5\cars\Ferrari-dino.html now this is my scenario, How do Search Engines see it and how do they rank it? Is it a Good or Normal or Bad SEO practice? If bad how dangerous it is for my sites SEO? i need your comments on my scenario.

• Automated Error Reporting in .NET Reflector - harnessing the most powerful test rig in existence

  - by Alex.Davies

  I know a testing system that will find more bugs than all the unit testing, integration testing, and QA you could possibly do. And the chances are you're not using it. It's called your users. It's a cliché that you should test so that you find your bugs rather than your users. Of course you should. But it's also a cliché that no software is ever shipped bug-free. Lost cause? No, opportunity! I think .NET Reflector 6 is pretty stable. In fact I know exactly how stable it is, because some (surprisingly high) proportion of its users tell me every time it crashes: If they press "Send Error Report", I get: And then I fix it. As a rough guess, while a standard stack trace is enough to fix a problem 30% of the time, having all those local variables in the stack trace means I can fix it about 80% of the time. How does this all happen? Did it take ages to code this swish system? Nope, it was one checkbox in SmartAssembly. It adds some clever code to your assembly to capture local variables every time an exception is thrown, and to ask your user to report it to you, with a variety of other useful information. Of course not all bugs show up as exceptions. But if you get used to knowing that SmartAssembly will tell you when an exception happens, you begin to change your coding style. Now, as long as an exception gets thrown in any situation you don't expect, you'll fix it if it ever happens. You'll start throwing exceptions liberally, and stop having to think about whether tiny edge cases are possible, as long as they throw an exception if they happen.

• Maintenance Plan Reporting - Append To File - Clean Up?

  - by Adam J.R. Erickson

  Background: (SQL Server 2005, Standard Ed.) I have a maintenance plan running backups, taking a full backup 1/day, and t-log every 15 minutes. I have it set to create a text file report of each run, but that creates A LOT of files on the file server. These are hard to sort through, which makes them less useful. Question: There is an option in "Reporting and Logging" settings for appending all logs together, but how do you clean this out? If you're appending to the same log file every time, how should you make sure this file doesn't grow indefinitely? Is there a build-in function to clean out portions of appended logs like there is for cleaning out individual old log files?

• How to get OpenSSH to use ksshaskpass under KDE?

  - by Guss

  When using a GNOME desktop on Ubuntu, if I use OpenSSH client to connect to another computer (running from the gnome-terminal), I get a single graphic popup asking for my private key's pass-phrase. After that I no longer need to enter my pass-phrase as it is cached by the SSH agent. Under KDE it doesn't work like that - when I start ssh from konsole, I get a text prompt for my pass-phrase every single time, even though ssh-agent is running. If I run ssh-add from the terminal then I can enter my pass-phrase on the terminal and it will be stored by ssh-agent and I won't get any more pass-phrase prompts, while if I run ssh-add the KRunner graphical command line ("Run" dialog) then I get a graphical prompt with the same behavior. The problem is I have to remember running ssh-add every time I log in to the desktop. How can I get ssh to behave under KDE, the same as it does on GNOME - the first time the pass-phrase is needed, pop up a graphical dialog and store the pass-phrase in the agent. I've installed ksshaskpass, but that didn't change anything.

• How to retain background colors when pasting between documents in Excel

  - by Iain Fraser

  I have a script that programatically generates excel spreadsheets - cleaning up ugly reports that are given to us from another organisation. For interests sake; I'm using PHPExcel to generate the "clean" reports. We get these reports every week for an event that happens every couple of months. The reports contain a list of attendees along with a group id that allows us to know that some attendees belong together. To help the event organisers out, I've taken the event ID and generated a unqiue color code (based on the hash of the event ID - truncated to 6 characters). This unique colour code is set as the background color of a cell in each row. This helps organisers quickly visually identify group members. Trouble is, when the organisers copy the rows from the weeks report into the master report (which contains all attendees, not just the ones that signed up this week) - all the colour-codes snap to the master template's color pallette. Thank you very much for your time All the best Iain

• How do I handle having too many links on a webpage because of my menu

  - by RandomBen

  I am developing a website that has a drop-down menu at the top of it. The Menu has around 100 links in it that are repeated on every page. Every page also has some number of links below the Menu that may or may not be in the menu itself. My issue is that Google says they generally don't like pages with more than 100 links on them. Is there any way to change the links on the menu so that they no longer "count" towards my max of 100 links? It seems like there should be an easy way to do this but their really doesn't seem to be. the rel=nofollow still counts towards the number of links on the page at least according to Google, so what other options do I have? I looked into where the 100 comes from and I found that it used to be here: http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=35769#2 but that is no longer the case. I found a more definitive and frankly muddier answer here: http://www.seomoz.org/blog/questions-answers-with-googles-spam-guru from Matt Cutts from 2007. Long story short, in 2007 they still felt 100 links was a good number but they stated you could go far beyond that. In fact, they said that pages with high PageRank could have 2-300. It did sound like having many links could reduce the PageRank of the page with all of the links or possibly all of the items linked to. Also, I know IIS7's SEO 1.0 toolkit suggests that pages should have no more than 250 links.

• moving from wpf to html5

  - by HighCore

  I don't even know if this is the right StackExchange site to post this question. If it isn't, please excuse me and please let me know which would be the right one. I am an experienced WPF developer, and I seriously love the technology. I feel pretty good when working with XAML, bindings, templates, triggers, MVVM and all the WPF world of goodness. Now I have recieved a job offer which surpasses my current salary by 50%. It a position to work as a C# developer in an ASP.Net MVC4 + HTML5 project. I have never EVER in my whole life worked with ASP.Net, nor HTML and I never ever did a web page or web application before. I certainly find myself worried that I will lose all the comfort and joy I live every day coding in WPF. And in the other hand I understand and have seen in these 3/4 months of job hunting that there's a LOT of ASP.Net and really really little or no WPF in the job market (at least here), so I somehow feel forced towards it. So, my question is: Can anybody who had to go thru this type of change tell me the pros and cons of working with these technologies from a developer's perspective? I don't care about open-source / non-microsoft or non-desktop, I care about REAL development experience in every day working with these techs, and whether ASP.Net MVC 4 + HTML + JS is as crappy as I think it is comparing it to WPF.

• Run as different user on a shortcut

  - by PhilPursglove

  How do I do this in Windows 7? On Windows XP I had the ability to mark a shortcut as being run by a different user, so that every time I ran it it would prompt me for a username/password. This let me have two shortcuts for things like SQL Server Management Studio, one for my normal account and one for my Domain Admins account which has access to production servers. I can get to the 'Run as different user' option with Shift+right-click, but I can't see an option anywhere that would let me mark the shortcut as doing this every time.

• SQL SERVER – Load Generator – Free Tool From CodePlex

  - by pinaldave

  One of the most common questions I receive is if there any tool available to generate load on SQL Server. Absolutely there is a fabulous free tool available to generate load on SQL Server on Codeplex. This tool was released in 2008 but it is still extremely relevant to generate the load on SQL Server as well works fabulously. CodePlex is a project initiated by Microsoft for hosting open source softwares. The best part of this SQL Server Load Generator is that users can run multiple simultaneous queries again SQL Server using different login account and different application name. The interface of the tool is extremely easy to use and very intuitive as well. One of the things which I felt needed improvement was a default configuration. As every single time when I was adding a query the default settings were showing up and I had to manually change that. However, when I went to Menu >> Tools >>Options I was really happy as it has options to change every single default which is available. Here one can give default username, password, database name as well various settings related to configuration. Additionally application logging is also possible through the options. A couple of other important points I noticed was the button to reset counters as well status bar containing useful information of Total Threads, Completed Queries and Failed Queries. I use this frequently for my load testing. What tool do you use for SQL Server Load Generator?

• How do I install FreeNX server so that it works correctly?

  - by Niklas

  I've tried every single possible way of installing the server now, I've read every how to available and I still can't get it to work. Please let me know in which step I do wrong. I'm using ubuntu 10.10. I will mainly be referring to the following how-to, but also this, and this one. First I add the ppa Install Freenx Download the special Freenx package as stated in the howto, fix ownership - install it Create custom SSH key Copy the file /var/lib/nxserver/home/.ssh/client.id_dsa.key to the client and import it in nomachine (windows 7 x64) Check that both the user I will be logging in with and the user nx is in AllowedUsers in the /etc/ssh/sshd_config file Check the port that ssh is listening on Login through nomachine with my regular user account in ubuntu I always receive the message "authentication failed for [user]" when I try to log in. And I can't see the user "nx" which is said to be created during installation when I look under System-Administration-"Users & Groups". Can anyone please enlighten me if there is any step that I miss or have misunderstood? Thank you very much! (Or is there an easier way of enabling remote desktop that it can be used with a windows machine? I prefer not using VNC because I was hoping of being able to get better performance than that. And when I tried using XRDP I only received a black screen on the client.)

• Database checksum features - redundant? useful?

  - by Eloff

  Just about every mainstream DB has a feature to calculate checksums per page, per sector, or per record. Now for a DB that does full recover after any crash, like PostgreSQL, is a checksum even useful? There will be no data loss as long as the xlog is ok, no matter what kind of corruption happened to the data itself, as the redo log is replayed every committed transaction will be restored. So checksums are useless on restore. Doesn't the filesystem or disk keep checksums anyway to detect corruption? So unless the checksum is per record, all it does is tell you there is corruption - which the OS should be yelling at you the minute you try to read it - so useless in operation? I can't imagine how a checksum can be helpful in any sane database - but since they all use them - I'd say that's just failure of imagination on my part. So how is it useful?

• Takeaways From CSO Roundtable New York

  - by Naresh Persaud

  Thanks to everyone who attended the Chief Security Officer Roundtable in New York last week. We were lucky to have Dennis Brixus, CSO of McGraw-Hill  as a guest speaker. In addition, Jeff Henley, provided a board level perspective on security. Amit Jasuja discussed Oracle's security formula.  A few takeaways from Jeff's talk that were interesting: Security is a board level issue. The challenge at the board level is that boards have short attention span. The CSO needs to be vigilant in educating the board on the strategic importance of security. Every CSO needs to think about cost. The CSO has to look at the economics of security and demonstrate fiduciary responsibility. We have to think of security as a business enabler. Security is the enabler that helps us expand into new markets and connect better with our customers and partners. While the CSO can't prevent every threat, we have to expect the CSO to have a plan.
