• Is Google showing ads from other companies or WordPress plugin is injecting ads which are not mine?

  - by Hafiz

  I am using WordPress for managing my blog sort of website, and I am using an Ad Injection plugin to place my ads where I want in a post. Plugin seems very good but I saw some ads which were not from ads networks which I was using. Now I have injected Google ads leaderboard at some place but I saw advertisement from this advertiser: http://www.adroll.com/about/privacy?utm_source=evidon&utm_medium=AdChoices&utm_campaign=privacy%2Bpolicy So I want to know whether ad injecting plugin is doing some trick or Google use ads from other networks too? Let me know so I can act accordingly and all good responses will be appreciated.

• Moving around/avoiding obstacles

  - by János Harsányi

  I would like to write a "game", where you can place an obstacle (red), and then the black dot tries to avoid it, and get to the green target. I'm using a very easy way to avoid it, if the black dot is close to the red, it changes its direction, and moves for a while, then it moves forward to the green point. How could I create a "smooth" path for the computer controlled "player"? Edit: Not the smoothness is the main point, but to avoid the red blocking "wall" and not to crash into it and then avoid it. How could I implement some path finding algorithm if I just have basically 3 points? (And what would it make the things much more complicated, if you could place multiple obstacles?)

• MS Tech Ed 2011 Coming Soon

  - by sonam

  Microsoft Tech ed 2010 was a great success. Infact  Most of such conferences always provide a great place to meet other  technology enthusiasts and ofcourse,whats in the pipeline for future products of a company or field.. And yet again,MS Tech ed India is coming on 23-25 march  in Banglore,India.Well,the place is  ofcourse right suited for any IT/Computing conference.After all,Its Silicon Valley of India.. From Last year.I remember  a session by Harish about  “Building pure client side apps with  Jquery and Microsoft Ajax .” Here’s the video: http://live.viasilverlight.com/TechEdOnDemand/Breakouts/TheWebSimplified1/Session4/AjaxClientSideApps.wmv At that time only,I got to know that jquery is so easy to use for  ajax or client side templating.Though I prefer jquery over  Microsoft Ajax many folds.UpdatePanel  is Dead for sure in my view. I believe,Web forms will be dead sooner or later with ASP.Net  MVC  gaining share many folds.(TODO:Learn MVC). The new standard is surely:JQUERY . Between,Last years videos and ppt’s  are available to browse and download: http://microsoftteched.in/2010/downloads.aspx After going through Tech Ad 2011 session agendas : http://www.microsoft.com/india/teched2011/agenda.aspx Few of my personal choices to watch would be: Day 1: a) Identity And Access Control in the Cloud        b)Windows 7 at  Home:Digitizing your Home.(Sounds cool.)        c) And ofcourse,Jquery and MS ajax(Lets see if MS can do something that’s not already happening with their version Of Ajax).. Day 2:  a) Lap Around Silverlight 5 and Html 5 as I have heard some hot talks that html5 will kill Silverlight,(I don’t see it in near future though).        b) Html 5 more than “Html 5”…Google will be seeing this one. Day3: a) Cross Browser applications in Azure       b)VS 2010 sessions of automated testing azure apps etc. Windows Phone 7 sessions will surely be of more interest now after MS-Nokia Deal. Though,Personally,I would want atleast some worth of  sessions on MS  future in Robotics,AI.Perhaps  I am looking at wrong place..(When is PDC?) And Since,Bill Gates  consider Robotics as the next big thing, Refer  this one : http://www.cs.virginia.edu/robins/A_Robot_in_Every_Home.pdf  I am sure,they wont loose this new hot spot to competitors,  like how google rules in Online  Search now.Robotics and AI will surely provide a big battlefield  for future.See,What IBM is doing with IBM Watson. OR see this, http://www.sciencedaily.com/releases/2011/02/110218083711.htm this is cool only if you can control your mind.Atleast,I’ll prefer regular driving (I would devote my mind seeing  people,places which we see on road).thats what jouney makes “cool”.:P.

• My boss has a different idea of a website's UX [migrated]

  - by NicoJuicy

  Let me explain the situation. I started transforming a "old (.Net 2.0)" Application into a webapplication. Problem here is, that no-one here is really acquainted with the UX of a website (Simple, efficient). Eventhough, i still have to regard that the website can be tailored to a customer needs through parameters (yeah, i know :s ) For example: I wanted to have a layout similar to invoicemachine (= as simple as possible). -- He wants a Ribbon toolbar. Going to a supplier gives the list of supplier -- He wants to display the "Create Supplier" screen where you can use the wildcards in a certain textbox, to search for a specific Supplier and then give the list of the suppliers. Also, i need 4 search/filter mechanisms: people can search per field with wildmarks can filter the suppliers search a keyword through all the data of a supplier filter the "list Suppliers" page by the first letter of the name. LIST Suppliers | A | D | Z Adam Wrincle ADD |EDIT |Delete Damzel InDistress ADD |EDIT |Delete Zorro ADD |EDIT |Delete I can't seem to get through to him, that the UX of a website needs to be differently than a Windows Application. If he wants to bring all the logic of the windows app into a website, why letting me build a website then? Stick to the old solution. Am i mistaking so hard or how could i convince / show him that an online-solution is something different than the offline solution. He already "saw" online solutions of other applications to get an idea, but if i suggest something he won't listen (if it's GUI / UX related, that is).

• My Codemash 2011 Retrospective

  - by Greg Malcolm

  I just got back from Codemash yesterday, and still on an adrenaline buzz. Here's my take on this years encounter: The Awesome Nearly everybody in one place Codemash is the ultimate place to catch up with community friends. This is my 3rd year visiting and I've got to know a great number of very cool people through various conferences, Give Camps and other community events. I'm finding more and more that Codemash is the best place to catch up with everybody regardless of technology interest or location. Of course I always make a whole bunch more friends while I'm there! Yay! Open Spaced I found the open spaces didn't work so well last year. This year things went a lot smoother and the topics were engaging and fresh. While I miss Alan Steven's approach of running it like an agile project, it was very cool to see that it evolving. Laptops were often cracked open, not just once but frequently! For example: Jasmine - Paired on a javascript kata using the Jasmine javascript test runner J - Sat in on a J demo from local J enthusiast, Tracy Harms Watir - More pairing, this time using Ruby with the watir-webdriver through cucumber. I'd mostly forgotten that Cucumber runs just fine without Rails. It made a change to do without. The other spaces were engaging too, but I think that's enough for that topic. Javascript Shenanigans I've already mentioned that I attended a Jasmine kata session. Jasmine is close to my heart right now every since I discovered it while on the hunt for a decent Javascript testing framework for a javascript koans project earlier this year. Well, it also got covered in the Java Precompiler and Pillar's vendor session, which was great to see. Node.js was also a reoccurring theme. Node.js in a nutshell? It's an extremely scalable Event based I/O server which runs on Javascript. I'd already encountered through a Startup Weekend project and have been noticing increasing interest of late. After encountering more node.js driven excitement from my peers at codemash I absolutely had to attend the open space on it. At least 20 people turned up and by the end we had some answers, a whole ton of new questions and an impromptu user group in the form of a twitter channel (#nodemash). I have no idea where this is going to go or how big it is going to become, but if it can cross the chasm into the enterprise it could become huge... Scala Koans I'm a bit of a Koans addict, and I really need more exposure to functional languages so I gave the Scala Koans precompiler a try. Great fun! I'm really glad I attended because I found I had a whole ton of questions. Currently the koans are available here, and the answers are here. Opportunities While we're on the subject can we change the subject now? Hai Gregory, You really need to keep the drinking for later in the day. I mean seriously, you're 34 and you still do this every single time! Sure, you made it to Chad Fowler keynote ok, but you looking a rather pale weren't you? Also might have been nice to attend 'Netflicks in the Cloud' instead of 'Sleeping It Off For People Who Should Know Better'. Kthxbye PS: Stop talking to yourself Not that I entirely regret it, I've had some of my greatest insights through late night drunken conversations at the CodeMash bar. Just might be nice to reign it in a little and get something out of the next morning too. Diversity This is something that is in the back of my mind because of conversations at Codemash as well as throughout the year; I'm realizing more and more how discouraging the IT profession is for women. I notice in the community there has been a lot of attention paid to stamping out harrasment, which is good, but there also seems to be a massive PR issue. I really don't have any solutions, but I figure it can't hurt to pay more attention to whats going on... And in Other News I now have a picture of Chad Fowler giving me more cowbell! Sadly I managed to lose the cowbell later on. Hopefully it's gone to a Better Place. The Womack Family Band joined in with the musicians jam this year. There's my cowbell again! Why must you hide from me? I also finally went in the water for the first time in all the I've been coming to codemash. Why did I wait so long?!?

• Which tool to use for "home banking"?

  - by Huygens

  I would like to manage my bank accounts in a secure manner on Ubuntu. I saw several applications in the Software Centre, but I don't know which one to choose. I don't need fancy features like stock options. I just have regular accounts which I want to follow, I don't want complicated stuff. As bank data are quite sensitive, I would highly prefer an application that does encryption of the data. Though, if you have a really cool app but it does not have this feature, as long as it offers to store the data in one dedicated place, I could do with encrypting that place. So what tool do you use that could fit my needs?

• What nameserver should I use?

  - by Qmal

  Let's say that I have site.com website that I bought at one place, but want to host on another place. I don't know what to do. Here is scenario. I bought site.com on company that is using their own nameservers - ns.a.com. And linked website to their own servers. I bought hosting on another company that is using nameservers - ns.b.com. Should I just change ns.a.com on my DOMAIN to ns.b.com? Or should I link all DNS entries on my domain control panel to host ip addresses?

• Managing user privileges, best practices [on hold]

  - by Loïc N.

  I'm am new to web development. I'm creating a website where different user can have different privileges, such as creating/editing/deleting a news, or adding/editing/deleting whatever kind of content on the website. I started by creating a "user type" that would indicate the user's privileges (such as "user", "newser", "moderator", "admin", and so on), but I quickly started noticing issues that made me think that this might be a naive approach to this issue. What if I want to give a regular user the right to edit a news (for whatever reason)? Then the user would be half "user", half "newser". But the system I use can only handle one user-type. So what would be the best practice here? I was thinking of removing the concept of roles (or "user-types" such as newser) and only have the concept of "privilege", where every user could have zero to many privileges. So, to re-use the above example, if I wanted a user to have the right to edit some news, I would only have to give him a "edit news" privilege. Is this the way to go?

• alot questings since i wanted to make a new SSB game or mario game(that use 3d models) [closed]

  - by user20465

  i have just started to study programming and i know already ppl will say why make a so big project like as a SSB game for a noob game development? cuz i always wanted a SSB engine like as Mugen is a fighter game engine but is not like as SSB´s gameplay + is not using 3d models too so i will call it SSBmugen(until i find a better title for it i got afew ideas for titles) also i wanted to make this game so it can use SSBbrawl files(models+animations mainly) the moveset+Stage coding files i wanted to redo cuz so anything can be possible like make a teleporter or a pipe teleporter(like as Super mario bros game) on a stag e or make some stuff there is impossible in SSBbrawl for moveset coding but is not in SSBmugen like make so a char. summon a Clone and the clone will do a attack and then is gone or some attacks/moves also i will make a moveset/stage Coding editor so it will be really easy to make moveset/stages coding for yours 3d models/animations moveset+stage Coding i mean: hitboxes/hurtboxes/moving Stuff/moving bones like cape or hair bones that is moving by wind effects or falling or other stuff like that/other stuff that needed to be coded i have planed to make a editor(for moveset/char. coding) or add the editor in brawlbox for my game so other ppl can easy make moveset/stages Coding to they´s models/animations so it will be easy so even kids can make a custom movesets/stages why using SSBbrawl files?: cuz ppl have made alot of models or textures/custom movesets/custom stages like goku/other anime/not brawl stuff for super smash bros brawl hacking(a.k.a modding) so ppl dont have to redo anything if they wanted to have the custom models or textures/custom movesets/custom stages from SSBbrawl to SSBmugen +there is the program named brawlbox that can open brawl files like model/animations and can edit models or animations and import models from 3ds max to be the right model format for SSBbrawl and i also wanted it so easy to add(a.k.a installer) Recolours or alt. models(like as oneslot doctor mario model over mario´s boneset) or textures/Movesets/new char. slots/new stages so easy so you only needing to download themplace them in right foldername them the right nameStart the gameRecolours or alt. models or textures/Movesets/new char. slots/new stages works an loading right so you wont needing to edit any files for add something so kids/not so smart ppl can easy use the mods other ppl is making/uploading for this game here is the file format i wanted to know if they can be readed/opened if making a game that use these files: .mld0(brawl model file) .chr0(model animation for moving/scale/rota the bones) .srt0(animations for texture like moving eyes or blinking) .vis0(Animations for get polygons to hide/show with visibilitybones on the model there is also some polygons there ) .brres(a file format where stuff like model files or textures or animations is inside) .pac(a file format where the .brres is inside to keep model+textures+model for the shadow in 1 file) .wav (for SoundFX effects or voices to char. or stages) i am sure that one is possible the .wav files is inside a other file format for brawl but that file can´t you add more .wav files inside only replace so i wanted the .wav files outside so its easy to add/replace/remove SoundFX effects or voices to char. or stages .brstm(brawl music file so the music is looped perfect so it loop in middel of the music and not start over again then the music is done) afew more file formats (mainly for the Graphics effects like fire/aura/hit effects if not needing to redo them)so only coding in the editor i will make is needed to be done for port a SSBB hack(a.k.a mod)(moveset/stage coding) to this game wanted the game to be able to load these files and load them right like if loading wait1.chr0(idle animation) it will also load at same time wait1.srt0/wait1.vis0 and all kinda of animations is inside the same .brres file i am needing since it to be able to load the file format i wanted cuz: -the animations can´t be converted to any other animation file format and i dont think ppl want to redo these animations(inc. me for Goku to SSBbrawl) -models can be converted but then they lose all the shader/materials stuff like a shine effect or lighting on the model -.brstm can be converted to .wav but then there will be no loop so i prefer it can load this file format too for the music to stage/menu -brawlbox is really easy to use for make animation for the char. and import models from 3ds max so even around "not too stupid" 10 year kids can make SSBB mods(not try to be rude but to say how easy it is) also i wanted the folder setup for characters/stages/moveset/other stuff to be like this: https://www.dropbox.com/s/2oolm5z5ri234tz/SSBmugen%20Folder%20setup.txt just uploaded a txt file since it is a wall of text and this post is already a wall of test so it easy to place stuff (if not i do a program for to that so it auto place the stuff on right place) not 100% sure what to use of game engine to make this possible but i got a dll file from that brawlbox program that can open/read/edit these file formats if that helps i also got open source of brawlbox i have kinda learned programming(since its kinda the same thing but still not 100% same) from Super smash bros modding/hacking like coding a moveset for the new animations/models + have readed alittle about it but i am soon starting for real to study it for ppl who is alittle confuse for what i am asking for here is the list: -what game engine should i use to make a SSB clone? but at same time to make all this stuff i just said possible so ppl can make they own mods and share them and use the already made mods from SSBbrawl? and easy to use aswell so noob programmors can use it? -where to learning programming on internet to be even more ready to make a game like this? and dont wanted to start in the small like making small boring 2d games that no one care about anyway ps. i am also planing a other project like as SSBmugen but it will be Super mario bros open (again tittle unsure but open means open source) i will make a Mario game engine that also use 3d models and can have 2d or 3d gameplay with any mario powerups/gameplay(from any mario platform games) there is ever made multiplayer like as in New super mario bros wii maybe multiplay over lan or online but for now over 1 PC also alittle planed for that to my SSBmugen a Level/world map editor for it too(easy to use so even kids can use it and make levels for it) so it just place the objects/enemies and options for them enemies since they are not 100% same AI in all mario game like to choose a goomba have AI from SM64 the Editor will be able to change the gameplay on a level while have a other gameplay on a other level like this: 1 level have Super mario bros 3 gameplay (then it will be a 3d model remake) a other level have super mario galaxy gameplay but in a Super mario 3d land level yet a other level have super mario 64 gameplay but with powerups from a other mario game like powerups from mario 3d land or can ride on Yoshi so you can easy remake your fav. level from a old mario game in this mario engine/editor or just make a custom one with yours fav. mario gameplay/powerups so it will be like turn off/on: walljump/triple jump/other kinda or jumps/2x punch and 1 kick+Air kick/SMG spin attack/Fludd/other stuff like that so you can make the gameplay from the first mario game to the newest or make custom gameplay on a level also the star(from 64/sunshine/galaxy) will be replaced with the flag from new super mario bros/mario 3d land since the game is not so much about getting stars its more about making/download the levels you wanted and share them to other ppl and play these level so after have killed like the boss from SM64 bomb omb field(if one have made that) you will get the flag instead of star since i wanted it to be simple to make levels in the editor to make the bosses/new enemies/new powerups/custom char. idk what to do to make that simple yet also thinking the mario game will use brawl files since it almost already got all needed animations/models for this since i dont wanted to redo animations/models and if needing more animations i can just make them easy in brawlbox since thats the program i am most used to make animations but that will be after my SSBmugen project if not this game will be easyer then SSBmugen to make since i am planing then 1 of them is done i use the that game as base to make the other (since both is kinda platfrom games and possible using same file format for both) also wanted to ask what is best to start with out of these 2 games? also will maybe make a DLC site(or ingame) for both of these games if they get done so it wont end up like as Mugen where you needing to look all over the internet to find the stuff you wanted but for my game all the mods for my game is on same place not sure about online mode for SSBmugen or super mario bros open but i can always add that then i get better at programming both games also need to have options on controls/if using joystick also that i have planed these game for a long time and got even more ideas for them but first i wanted to get them to work so i can add the other stuff later(like DLC or online mode or some other stuff later) right now i know 0,0001% to programming(in my option) maybe i know more then that since i have been study it alittle but i learning while making stuff like this that was also my plan for make these game learn while making them and get better to programming so again i say it i kinda dont want to hear dont do these projects cuz i already know it will be hard so dont wanted so much to heard stuff like: you can´t do it since you just started learning programming or this project will fail since somewhere i needing to get started with programming and this is where i want to start to make my dream games(possible other´s dream games too) and i dont think this project will fail if i work hard on it (as i possible will) and ppl will maybe help i think this was all my questing/ideas for now (sorry for it sounds more like ideas then questings) but i needing to say my ideas so you ppl can see what i needing to use for make this possible

• What are the best social places for programmers to interact?

  - by Chevex

  I know this is not really the right place for this type of question, but I figure it will get me started and hopefully won't be closed right off the bat. I love the programming industry a lot, but I don't have many colleagues that aren't introverted and/or anti-social, or self-centered. What are some good places online to find programming friends that I could share my adventures with? I love stack overflow but it is more technical and doesn't really allow you to put up a personal project just for people to see and critique. Any suggestions? A good forum would be great! The only ones I can find are usually full of inexperienced people who just "want" to be a programmer. I'm looking more for a place who's members are already programmers discussing programming topics.

• Interview with Koen Aben, Supply Chain Director of WE Fashion

  - by user801960

  We recently spoke to Koen Aben, the Supply Chain Director of WE Fashion, who gave us some insight into how Oracle supported the international fashion retailer through the completion of a large scale integration project across its 340 European stores. Koen explains the reasoning behind the project which was to create a common retail foundation and to integrate and align working processes to drive insight and enable continued growth. It is always good to hear from someone of Koen’s experience who can articulate the benefits of partnering with the right company for such an extensive project as this. Koen explains that a crucial element of such a project is to unify business applications into a common platform, adding that for successful growth, retailers really need to achieve enterprise-wide alignment. At the start of the three year project, WE Fashion’s application platform was fragmented impacting the company’s ability to support sustained growth. In light of this, WE Fashion invested in its processes, systems, teams and partnerships to build the needed retail foundation. Now after successfully completing the project, the basis is in place to ensure that growth is unimpeded. In the video, Koen Aben highlights some of the factors necessary for the success of the project as: Having an understanding that the process of creating a growth platform for a company is a long journey Accepting that during a lengthy project such as this, there will be high and low points experienced within the project team and the business, but that the relationship with your partners is crucial to the success of the project. Having the correct team in place will prove to be the “lynch –pin” of any successful project Oracle supported Koen and his team in implementing this project, and is recognised for the role it played during this development in partnership with the company. On his experience with working with the Oracle team, Koen points out that in the critical situations, Oracle was there to ensure that the right people were in place whenever needed and this was key to ensuring the project’s success. Since Oracle is one of the few providers that can offer an enterprise-wide retail platform, our best practice approach is key to connecting interactions throughout the business to enable insight and optimise operations. This is a great example of a large scale international retail project, where the true success of its completion is reflected in how proud the company is about what has been achieved, and the fact that results are already being seen.

• recurring billing / profiles management system

  - by Karl Cassar

  As a company, we have various recurring fees which our clients pay - these can include: hosting plans maintenance agreements SLAs ... I would like to know if anyone knows of a good, web-based recurring billing / payments management system which we could use to help us get more organised regarding this aspect of our business. Basically, we would need to: Create recurring profiles, e.g: Hosting, emails / domain services @ 200eur / year Be able to give free / extend the subscription period, for any reason. Also, we don't have specific products which we would like to choose and charge - all these recurring fees are discussed with the clients, and are created on a per-client basis. I'm not sure if this is the best place to ask for, however since I think most 'webmasters' require such a system to keep track of payment, I thought this would be the place to go for. Thanks in advance!

• My program at #MIX10

  - by Laurent Bugnion

  Getting ready to fly to Vegas and MIX10 is really an exciting time! It is also a very busy time, because we are working on a few projects that will be shown on stage, I have my presentation to prepare, and of course as always the book… though these days it has been a bit on the back burner to be honest ;) I arrive in Vegas on Sunday evening around 10PM, so I won’t be able to make it to the traditional IdentityMine dinner this year. I am sure it will be fun nonetheless! My session: Understanding the MVVM pattern http://live.visitmix.com/MIX10/Sessions/EX14 My session is scheduled on the first day, which is awesome, so I am crossing my fingers and hoping that the MIX team doesn’t change it at the last minute… The session will take place on Monday, the 15th of March, 2PM, Room Lagoon F Important: remember that the USA are moving to Summer time on Sunday, so don’t forget to adjust your watches!! Ask the Experts On Monday evening, I will attend the Ask the Experts event, which is taking place between 5Pm and 6:30PM in the main meal hall. This will be a great occasion to grab a beer and talk about code. The Commons MIX has a great place called the Commons, a great location to chill between sessions, and meet tons of interesting people. I love the Commons and plan to spend a lot of time there to meet as many people as I can. Parties I was invited to a few parties, and will do my best to avoid conflicts :) I plan to be at the following events: Silverlight Mixers on Monday evening Insiders MIX party on Tuesday Silverlight partner happy hour on Tuesday too This is a lot of fun, but at the same time we all know that the best value of a conference is to meet people face to face. This is just the right occasion.  And on Thursday… On Thursday I will be attending a Silverlight event at the Luxor. It will be a very busy day, perfect way to end the conference. I fly back home on Friday morning, but due to a long stop in Washington DC (where I intend to go downtown and take pictures… except if the weather is bad, in which case I will probably go to the museum of flight), I will reach home only on Sunday. Getting hold of me The best way to reach me during MIX is to send me a message on Twitter. I will regularly tweet my location at the conference, so make sure to come and meet me. I am eager to make new friends, to talk about the fantastic jobs we did in WPF and Silverlight over the past year and hear your war stories! http://www.twitter.com/lbugnion   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• All day optimizer event....

  - by noreply(at)blogger.com (Thomas Kyte)

  I've recently taken over some of the responsibilities of Maria Colgan (also known as the "optimizer lady") so she can move onto supporting our new In Memory Database features (note her new twitter handle for that: https://twitter.com/db_inmemory ).To that end, I have two one day Optimizer classes scheduled this year (and more to follow next year!).  The first one will be Wednesday November 20th in Northern California.  You can find details for that here: http://www.nocoug.org/ .The next one will be 5,500 miles (about 8,800 km) away in the UK - in Manchester.  That'll take place immediately following the UKOUG technical conference taking place the first week of December on December 5th.  You can see all of the details for that here: http://www.ukoug.org/events/tom-kyte-seminar-2013/I know I'll be doing one in Belgrade early next year, probably the first week in April. Stay tuned for details on that and for more to come.

• How should I update Ajax Control Toolkit in VS 2010?

  - by Soham

  Suppose if there is a new version available of Ajax Control Toolkit then how should I install/update it in my visual studio 2010 which has already install older version of same toolkit? I would like to install new one while older toolkit would totally uninstalled, because mostly new toolkit always has all controls that were in the old toolkit & also some new controls. Then 1) Should I've to remove .dll file in my toolkit installation folder and place new .dll file there? If I do so then will VS 2010 automatically delete older entries of toolkit controls in .NET Components list and place new control there? Or 2) Should I've to uninstall old toolkit manually i.e delete .dll file and uncheck all entries in .NET Components list & after that install new one from scratch?

• Cluster failover and strange gratuitous arp behavior

  I am experiencing a strange Windows 2008R2 cluster related issue that is bothering me. I feel that I have come close as to what the issue is, but still don't fully understand what is happening. I have a two node exchange 2007 cluster running on two 2008R2 servers. The exchange cluster application works fine when running on the "primary" cluster node. The problem occurs when failing over the cluster ressource to the secondary node. When failing over the cluster to the "secondary" node, which for instance is on the same subnet as the "primary", the failover initially works ok and the cluster ressource continues to work for a couple of minutes on the new node. Which means that the recieving node does send out a gratuitous arp reply packet that updated the arp tables on the network. But after x amount of time (typically within 5 minutes time) something updates the arp-tables again because all of a sudden the cluster service does not answer to pings. So basically I start a ping to the exchange cluster address when its running on the "primary node". It works just great. I failover the cluster ressource group to the "secondary node" and I only have loss of one ping which is acceptable. The cluster ressource still answers for some time after being failed over and all of a sudden the ping starts timing out. This is telling me that the arp table initially is updated by the secondary node, but then something (which I haven't found out yet) wrongfully updates it again, probably with the primary node's MAC. Why does this happen - has anyone experienced the same problem? The cluster is NOT running NLB and the problem stops immidiately after failing over back to the primary node where there are no problems. Each node is using NIC teaming (intel) with ALB. Each node is on the same subnet and has gateway and so on entered correctly as far as I am concerned. Edit: I was wondering if it could be related to network binding order maybe? Because I have noticed that the only difference I can see from node to node is when showing the local arp table. On the "primary" node the arp table is generated on the cluster address as the source. While on the "secondary" its generated from the nodes own network card. Any input on this? Edit: Ok here is the connection layout. Cluster address: A.B.6.208/25 Exchange application address: A.B.6.212/25 Node A: 3 physical nics. Two teamed using intels teaming with the address A.B.6.210/25 called public The last one used for cluster traffic called private with 10.0.0.138/24 Node B: 3 physical nics. Two teamed using intels teaming with the address A.B.6.211/25 called public The last one used for cluster traffic called private with 10.0.0.139/24 Each node sits in a seperate datacenter connected together. End switches being cisco in DC1 and NEXUS 5000/2000 in DC2. Edit: I have been testing a little more. I have now created an empty application on the same cluster, and given it another ip address on the same subnet as the exchange application. After failing this empty application over, I see the exact same problem occuring. After one or two minutes clients on other subnets cannot ping the virtual ip of the application. But while clients on other subnets cannot, another server from another cluster on the same subnet has no trouble pinging. But if i then make another failover to the original state, then the situation is the opposite. So now clients on same subnet cannot, and on other they can. We have another cluster set up the same way and on the same subnet, with the same intel network cards, the same drivers and same teaming settings. Here we are not seeing this. So its somewhat confusing. Edit: OK done some more research. Removed the NIC teaming of the secondary node, since it didnt work anyway. After some standard problems following that, I finally managed to get it up and running again with the old NIC teaming settings on one single physical network card. Now I am not able to reproduce the problem described above. So it is somehow related to the teaming - maybe some kind of bug? Edit: Did some more failing over without being able to make it fail. So removing the NIC team looks like it was a workaround. Now I tried to reestablish the intel NIC teaming with ALB (as it was before) and i still cannot make it fail. This is annoying due to the fact that now i actually cannot pinpoint the root of the problem. Now it just seems to be some kind of MS/intel hick-up - which is hard to accept because what if the problem reoccurs in 14 days? There is a strange thing that happened though. After recreating the NIC team I was not able to rename the team to "PUBLIC" which the old team was called. So something has not been cleaned up in windows - although the server HAS been restarted! Edit: OK after restablishing the ALB teaming the error came back. So I am now going to do some thorough testing and i will get back with my observations. One thing is for sure. It is related to Intel 82575EB NICS, ALB and Gratuitous Arp.

• Which token from a long User-Agent should I use in robots.txt?

  - by Gaia

  The definition of User-Agent states that several tokens can be included, as deemed necessary by the client. I want to block certain bots via robots.txt and I am confused as to which part of the User-Agent string to use, especially for more obscure bots. For example: Mozilla/5.0 (compatible; uMBot-LN/1.0; mailto: [email protected])" JS-Kit URL Resolver, http://js-kit.com/ Mozilla/5.0 (compatible; SEOkicks-Robot +http://www.seokicks.de/robot.html Do I use the second token? Can tokens contain spaces, or did the SEOkicks folks forget a semicolon after SEOkicks-Robot? I don't actually intend on making my question specific to a couple bots - I want to know the guideline: which part of UA do I place in robots.txt for these exotic bots with UA as long as a haiku? User-agent: uMBot-LN/1.0 Disallow: / PS: Thank you but I do not need to hear that undesirable bots are better blocked with mod_security. I already have commercial mod_sec rules in place.

• Cannot turn off password

  - by user70267

  Cannot authenticate without a password It did not fix my problem. If I create an admin account without password in the first place, what should I enter in place of the password? Also, how to perform administrative actions (such as sudo or downloading apps from Ubuntu Software Center) without password? How to remove the password entirely from my admin accounts? Note: In Windows 7, when you do not set a password or remove the existing password for an administrator, that administrator can be used to authenticate without a password. Leave the password blank and you can do anything.

• How do I restore a backup of my keyring (containing ssh key passprases, nautilus remote filesystem passwords and wifi passwords)?

  - by con-f-use

  I changed the disk on my laptop and installed Ubuntu on the new disk. Old disk had 12.04 upgraded to 12.10 on it. Now I want to copy my old keyring with WiFi passwords, ftp passwords for nautilus and ssh key passphrases. I have the whole data from the old disk available (is now a USB disk and I did not delete the old data yet or do anything with it - I could still put it in the laptop and boot from it like nothing happend). The old methods of just copying ~/.gconf/... and ~/.gnome2/keyrings won't work. Did I miss something? 1. Edit: I figure one needs to copy files not located in the users home directory as well. I copied the whole old /home/confus (which is my home directory) to the fresh install to no effect. That whole copy is now reverted to the fresh install's home directory, so my /home/confus is as it was the after fresh install. 2. Edit: The folder /etc/NetworkManager/system-connections seems to be the place for WiFi passwords. Could be that /usr/share/keyrings is important as well for ssh keys - that's the only sensible thing that a search came up with: find /usr/ -name "*keyring* 3. Edit: Still no ssh and ftp passwords from the keyring. What I did: Convert old hard drive to usb drive Put new drive in the laptop and installed fresh version of 12.10 there Booted from old hdd via USB and copied its /etc/NetwrokManager/system-connections, ~/.gconf/ and ~/.gnome2/keyrings, ~/.ssh over to the new disk. Confirmed that all keys on the old install work Booted from new disk Result: No passphrase for ssh keys, no ftp passwords in keyring. At least the WiFi passwords are migrated.

• I need recommendations on free, open source, PHP-based business intelligence widget frameworks [on hold]

  - by Volomike

  I'm a PHP developer on Linux, and my manager wants a business intelligence dashboard. He wants to see in real-time our profit/loss stuff in fancy charts, based on our software sales. I could code it all from scratch and use Google Charts API or some other charts API to help me. However, I wanted to know if there was a free, open source, PHP-based business intelligence package out there, or some sort of widget framework that I could start with. That way, I can build the BI widgets inside that framework and not have to do everything from scratch. I apologize ahead of time if this is the wrong stackexchange where to place this query. I don't know where to place this query, and do want to follow the rules.

• Green IT : Microsoft et Google peuvent mieux faire, selon le rapport annuel de Greenpeace

  Green IT : Microsoft et Google peuvent mieux faire, selon le rapport annuel de Greenpeace Quand les écolos mettent leur nez dans le milieu de l'informatique, certaines firmes se font tapper sur les doigts. De bons points ont cependant été accordés à Cisco et Ericsson, qui sont arrivés en première position des entreprises informatiques ayant le moins d'impact sur les changements climatiques. Malgré son lobbying en faveur des énergies propres et ses investissements dans les énergies renouvelables, Google obtient un mauvais résultat et se place à la 6éme position.

• Count unique visitors by group of visited places

  - by Mathieu

  I'm facing the problem of counting the unique visitors of groups of places. Here is the situation: I have visitors that can visit places. For example, that can be internet users visiting web pages, or customers going to restaurants. A visitor can visit as much places as he wishes, and a place can be visited by several visitors. A visitor can come to the same place several times. The places belong to groups. A group can obviously contain several places, and places can belong to several groups. Given that, for each visitor, we can have a list of visited places, how can I have the number of unique visitors per group of places? Example: I have visitors A, B, C and D; and I have places x, y and z. I have these visiting lists: [ A -> [x,x,y,x], B -> [], C -> [z,z], D -> [y,x,x,z] ] Having these number of unique visitors per place is quite easy: [ x -> 2, // A and D visited x y -> 2, // A and D visited y z -> 2 // C and D visited z ] But if I have these groups: [ G1 -> [x,y,z], G2 -> [x,z], G3 -> [x,y] ] How can I have this information? [ G1 -> 3, // A, C and D visited x or y or z G2 -> 3, // A, C and D visited x or z G3 -> 2 // A and D visited x or y ] Additional notes : There are so many places that it is not possible to store information about every possible group; It's not a problem if approximation are made. I don't need 100% precision. Having a fast algorithm that tells me that there were 12345 visits in a group instead of 12543 is better than a slow algorithm telling the exact number. Let's say there can be ~5% deviation. Is there an algorithm or class of algorithms that addresses this type of problem?
