• Google doesn't seem to update the description or title of my homepage

  - by Dayson

  Before we launched our website, we had set up a "coming soon" page and google picked up the title and description from its contents. So the description in the search results said, "Coming soon! Visit epicwhale.org for updates." It's been a few weeks since we launched our website. We've even created a sitemap and submitted it to google. In the google webmaster panel, the pages have been crawled and all the pages are appearing as expected on google, EXCEPT the homepage which is still not updated! The title and description of the homepage in google search results still says coming soon.. The website I am referring to is textmewidget.com and below are the images of the search result. Google: http://i.imgur.com/vAkJg.png I checked on bing too, but it appears to be fine there. Bing: http://i.imgur.com/Q8O6L.png All other pages seem to be indexed fine on google. I don't even have any crawl errors in my reports. So what seems to be the problem? I've already waited for 2 weeks. Thanks in advance!

• Difficulty / Process for mobile 2D multiplayer RPG game

  - by user2827214

  I'm looking to develop a 2D multiplayer RPG game for Android, with a bird's eye view similar to that of zelda/pokemon. The game is very simple in all ways since my intent is for thousands of players to occupy the same world which I imagine requires good performance. However, I am unsure about the performance requirements of two properties: the tile map that is used as a background is dynamic (interactive). For example, a player steps in the water, and the water turns black. Every tile in the game does this. the tile map is the same object used for all players, but it is displayed differently on each user's mobile device, even though the players exist in the same world. For example, the water that turned black is displayed as red on all other players' screens. I have knowledge of java, but almost none regarding game dev. tools. Is there a best process for these requirements? Should I develop in pure java, or use some tool like Slick2D etc.? How performance intensive are these properties, if even possible? Edit: There are no collisions in the game or difficult animations, I imagining simply changing colors of the tiles like in the examples, and a client-server architecture

• Why would 70-persistent-net.rules have no effect?

  - by Wes Felter

  I've got a saucy server with a lot of NICs and they end up with weird names like "rename19". I know interface names can be changed by modifying the /etc/udev/rules.d/70-persistent-net.rules file. The first clue that something is wrong is that that file did not exist even though it's supposed to be created automatically. So I decided to write my own based on advice from Linux From Scratch: ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:06:00.0", NAME="eth0" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:06:00.1", NAME="eth1" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:06:00.2", NAME="eth2" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:06:00.3", NAME="eth3" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:0c:00.0", NAME="mezz0" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:0c:00.1", NAME="mezz1" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:1b:00.0", NAME="slot1a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:1b:00.1", NAME="slot1b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:20:00.0", NAME="slot2a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:20:00.1", NAME="slot2b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:11:00.0", NAME="slot3a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:11:00.1", NAME="slot3b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:8b:00.0", NAME="slot4a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:8b:00.1", NAME="slot4b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:90:00.0", NAME="slot5a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:90:00.1", NAME="slot5b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:95:00.0", NAME="slot6a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:95:00.1", NAME="slot6b" (I'm matching on PCI IDs instead of MAC addresses because I have multiple identical machines that I want to apply this configuration to.) After rebooting, nothing has changed. It's like these rules aren't even being read. There's not much going on in dmesg either: $ dmesg | grep udev [ 3.196629] systemd-udevd[323]: starting version 204 [ 6.719140] systemd-udevd[550]: starting version 204 [ 38.695050] init: udev-fallback-graphics main process (1658) terminated with status 1

• text extraction from video game dialogue files [on hold]

  - by wdwvt1

  As part of an academic project, I am trying to access the dialogue files (whether audio or text) from a variety of sports video games (Madden or NBA 2kX would be fantastic). I have searched extensively on other sites (scholarly text-mining publications, r/gaming, r/madden, modding sites, etc.) for guidance in how to extract dialogue files, but have been unsuccessful. Given that I don't have even the domain specific language to ask the right question (i.e. the resources I am seeking are out there, I just can't find them) I am asking the SE game dev community for help with the 2 following questions: Is there a canonical resource that I should study that would get me started with how to extract text or audio files from games? I am very fluent in python, which usually excels at mining information from sources, but I struggle with knowing where to start with a video game (as opposed to a more familiar database with a defined API). Is this even feasible, or are protections included with newer games (e.g. NBA 2k13) going to make extraction of these resources in a programmatic way impossible? Thank you for your help!

• Collision detection in 3D space

  - by dreta

  I've got to write, what can be summed up as, a compelte 3D game from scratch this semester. Up untill now i have only programmed 2D games in my spare time, the transition doesn't seem tough, the game's simple. The only issue i have is collision detection. The only thing i could find was AABB, bounding spheres or recommendations of various physics engines. I have to program a submarine that's going to be moving freely inside of a cave system, AFAIK i can't use physics libraries, so none of the above solves my problem. Up untill now i was using SAT for my collision detection. Are there any similar, great algorithms, but crafted for 3D collision? I'm not talking about octrees, or other optimalizations, i'm talking about direct collision detection of one set of 3D polygons with annother set of 3D polygons. I thought about using SAT twice, project the mesh from the top and the side, but then it seems so hard to even divide 3D space into convex shapes. Also that seems like far too much computation even with octrees. How do proffessionals do it? Could somebody shed some light.

• Learning Electronics & the Arduino Microcontroller

  - by Chris Williams

  Lately, I've had a growing interest in Electronics & Microcontrollers. I'm a loyal reader of Make Magazine and thoroughly enjoy seeing all the various projects in each issue, even though I rarely try to make any of them. I've been reading and watching videos about the Arduino, which is an open source Microcontroller and software project that the people at Make (and a lot of other folks) are pretty hot about. Even the prebuilt hardware is remarkably inexpensive , although there are kits available to build one from the base components. (Full disclosure: I bought my first soldering iron... EVER... just last week, so I fully acknowledge the likelihood of making some mistakes. That's why I'm not trying to do the "build it yourself" kit just yet. It's also another reason to be happy the hardware is so cheap.) There are a number of different Arduino boards available, but the two that have really piqued my interest are the Arduino UNO and the NETduino. The UNO is a very popular board, with a number of features and is under $35 which means I won't hurl myself off a bridge when I inevitably destroy it. The NETduino is very similar to the Arduino UNO and has the added advantage of being programmable with... you guessed it... C#. I'm actually ordering both boards and some miscellaneous other doodads to go with them.  There are a few good websites for this sort of thing, including www.makershed.com and www.adafruit.com. The price difference is negligible, so in my case, I'm ordering from Maker Shed (the Make Magazine people) because I want to support them. :) I've also picked up a few O'Reilly books on the subject which I am looking forward to reading & reviewing: Make: Electronics, Arduino: A Quick Start Guide and Getting Started With Arduino (all three of which arrived on my doorstep today.) This ties in with my "learn more about robotics" goals as well, since I'll need a good understanding of Electronics if I want to move past Lego Mindstorms eventually.

• Collision detection, stop gravity

  - by Scott Beeson

  I just started using Gamemaker Studio and so far it seems fairly intuitive. However, I set a room to "Room is Physics World" and set gravity to 10. I then enabled physics on my player object and created a block object to match a platform on my background sprite. I set up a Collision Detection event for the player and the block objects that sets the gravity to 0 (and even sets the vspeed to 0). I also put a notification in the collision event and I don't get that either. I have my key down and key up events working well, moving the player left and right and changing the sprites appropriately, so I think I understand the event system. I must just be missing something simple with the physics. I've tried making both and neither of the objects "solid". Pretty frustrating since it looks so easy. The player starting point is directly above the block object in the grid and the player does fall through the block. I even made the block sprite solid red so I could see it (initially it was invisible, obviously).

• Forum engine with full LDAP integration [closed]

  - by Andrian Nord

  We are looking for forum engine which may actually maintain user data into LDAP, maybe via mods. Core point is about ability to maintain the data, i.e. all user profile settings, like nickname, password, email, avatar, birthday and others (preferably configurable). One example of good ldap integration, level of which I'm expecting, is drupal's ldap integration, which allows to map any user's attribute into ldap and keeps it in sync with database. Year ago I've done a small research over existing Free&FOSS engines and find out few forum engines with LDAP integration, namely SFM, phpBB and something else. The most maintained solution were provided by phpBB3, which supports LDAP integration out-of-box, but it is unable to sync data with changes in LDAP server made by other software. Actually it wasn't even propagating changes back, I'm not saying about ability to map additional attributes (other than name/password/email). Also, I haven't found any forum with architecture which have proper abstraction over user settings, thus I doubt that this engines (including phpBB) are possible to mod such functionality without introducing dramatic changes into core codebase. More recent research showed that even some commercial software, like IPB is unable to keep it's database synced with LDAP directory and map additional attributes. In other words, all support I've seen so far is simple user creation upon first user's login, which is not good for us, as forum is not primary site and should not maintain it's own users base (to reduce risk of possible collisions). LDAP import is required due to many other services (ftp, email, jabber, drupal site) using same users base. Currently we have forum embedded into Drupal site, but we are unsatisfied with it's features. BTW, we are using Linux and this is not duplicate of this question, as it's author seems to be satisfied with behaviour described above. So, my question is: Are there any (preferably FOSS&free) forum engines that may import, export, keep in sync, or otherwise integrade with LDAP user database (preferably with ability to map additional fields to ldap attributes)?

• Why is apt-get --auto-remove not removing all dependencies?

  - by Mike

  I just installed a package (dansguardian in this case) and apt told me that I had unmet dependencies. # sudo apt-get install dansguardian Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed: clamav clamav-base clamav-freshclam libclamav6 libtommath0 Suggested packages: clamav-docs squid libclamunrar6 The following NEW packages will be installed: clamav clamav-base clamav-freshclam dansguardian libclamav6 libtommath0 0 upgraded, 6 newly installed, 0 to remove and 0 not upgraded. Need to get 0 B/4,956 kB of archives. After this operation, 14.4 MB of additional disk space will be used. Do you want to continue [Y/n]? So I installed it and the dependencies. So far so good. Later on, I decide that this package just isn't the package for me, so I want to remove it and all of the other junk it installed with it since I'm not going to be needing any of it: # sudo apt-get remove --auto-remove --purge dansguardian Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED: dansguardian 0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded. After this operation, 1,816 kB disk space will be freed. Do you want to continue [Y/n]? However it is only removing that one specific package. What about clamav clamav-base clamav-freshclam libclamav6 libtommath0? Not only did it not remove them, but clamav was actually running a daemon that loads every time the computer boots. I thought that --auto-remove would remove not only the packages, but also the dependencies that were installed with it. So basically, without going through the apt history log file (if I even remember to do so, or if I even remember that a specific package I installed 3 months ago had dependencies along with it), is there a way to remove a package and all of the other dependencies that were installed like in this case?

• What is the role of traditional issue tracker when Scrum / Kanban board is used?

  - by Borek

  From a very high level view, to me it seems there are generally 2 types of Project Management tools: Traditional issue trackers like Fogbugz, JIRA, BugZilla, Trac, Redmine etc. Virtual card boards / agile project management tools like Pivotal Tracker, GreenHopper, AgileZen, Trello etc. Sure, they overlap in one way or another, e.g. Pivotal Tracker tasks can be imported to JIRA, GreenHopper itself is implemented on top of JIRA issue base etc. but I think one can still see the difference in orientation between those two types of tools. Traditional issue tracker seems to be used even in companies otherwise doing agile project management. My question is, why do they do that? I also feel that we should use an issue tracker in my company but when I'm thinking about it, I'm not actually sure why should we need it. For example, Trello development seems to be managed by using Trello itself (see this virtual wall) even though they have access to Fogbugz, one of the best issue trackers around. So maybe we don't need traditional issue tracker when we'll be doing 100% of our work in an agile manner using one of the agile PM tools?

• App to make a video from photos?

  - by chtfn

  I was wondering what could be a good app (with a GUI ;) ) for making a video from a bunch of photos or images, to create a time-lapse video, or a stop-motion animation, or even a video like this one. The idea is to set a really small time between each photo, but also to be able to change this time every so often, or add some effects, to make the succession smoother in particular. What would be perfect is a function that allows automatic cropping of the photos as well as exposure adjustment so they all have the same background and so the time-lapse video looks smoother. I know about the slide show app "Imagination" but the interval can not go under one second. Cheers! Edit: here is my progress, also thanks to the first answer: I tried Luciole, it is really simple and promessing, but pretty buggy, and I only could export an average video in .dv format (mpg2 and avi don't work). Apparently, it has difficulties when changing the fps. I also tried StopMotion: also pretty buggy, I had to go into preferences and modify the encoding commands to get a result, but it's the best result I got so far. But none of those has effects to make transitions smoother... I tried several diaporama apps: Imagination doesn't handle more than 1 image per second; PhotoFilmStrip (repo version and latest version from website): same problem even though you can go down to 0.1 second per image, it still behaves wierdly (going back to 1 second automatically); Videoporama: doesn't start at all on 12.04. Any other idea, folks?

• Tracking feature requests for small-scale components

  - by DXM

  I'm curious how other development teams (especially those that work in moderate to large development groups) track "future" features/wishlists for functionality for internally developed frameworks or components. I know the standard advice is that a development team should find one good tool for tracking bugs/features and use that for everything and I agree with that if the future requests are for the product itself. In my company we have an engineering department, which is broken up into multiple groups and within each there can be one to several agile teams. The bug tracking product we use has been "a leader since 1997" (their UI/usability seems to also be evaluated against that year even today) but my agile team or even group doesn't really control what is being used by the whole department. What we are looking to track is not necessarily product features but expansion/nice to have functionality for internal components that go into our product. So to name a few for example... framework/utility library on top of CppUnit which our developers share low-level IPC communications framework Common development SDK that myself and several other team leads started to help share some common code/tools at the department-wide level (this SDK is released as internal "product" to each of the groups). Is the standard practice to use the one bug tracking tool? Or would it make more sense to setup something more localized specifically for our needs and maintain it ourselves? It's also unclear how management will feel if developers start performing "IT" roles of maintaining software and servers. At the same time, right now, we use excel files, internal wiki and MS OneNote for this kind of stuff and that just doesn't feel right. (I'm afraid to ask for actual software recommendations, since that might make this question more localized or something. Also developers needs this way more than management, so it would be nice to find something either free or no more than the cost of a happy hour).

• Advice: How to convince my newly annointed team lead against writing the code base from scratch

  - by shan23

  I work in a pretty reknowned MNC, and the module that I work in has been assigned to a new "lead". The code base is pretty huge (~130K or more, with inter dependencies on other modules) , but stable - some parts have grown ugly over the years, but its provably in working state. (Our products are running for years on them, even new ones). The problem is, our lead wants to rewrite the code from scratch, to encompass "finer granularity and a proactive design". I know in my guts thats not a very good idea, but how do I convince him/the rest of the team(who are pretty much more senior than me in terms of years of exp), without sounding too pedantic myself (Thou shalt not rewrite , as Joel et al have clear articles prohibiting it)? I have a good working relation with the person concerned, and don't want to ruin it, but neither do I want to be party to a decision which would surely plague us for years to come !! Any suggestions for a milder,yet effective approach ? Even accounts of how you have tackled such a situation to your liking would help me a lot! EDIT: The code base I'm talking about is not a product/GUI, but at kernel level with all the critical functionalities for our product. I hope now you know why i sound so apprehensive !!

• Is micro-optimisation important when coding?

  - by BozKay

  I recently asked a question on stackoverflow.com to find out why isset() was faster than strlen() in php. This raised questions around the importance of readable code and whether performance improvements of micro-seconds in code were worth even considering. My father is a retired programmer, I showed him the responses and he was absolutely certain that if a coder does not consider performance in their code even at the micro level, they are not good programmers. I'm not so sure - perhaps the increase in computing power means we no longer have to consider these kind of micro-performance improvements? Perhaps this kind of considering is up to the people who write the actual language code? (of php in the above case). The environmental factors could be important - the internet consumes 10% of the worlds energy, I wonder how wasteful a few micro-seconds of code is when replicated trillions of times on millions of websites? I'd like to know answers preferably based on facts about programming. Is micro-optimisation important when coding? EDIT : My personal summary of 25 answers, thanks to all. Sometimes we need to really worry about micro-optimisations, but only in very rare circumstances. Reliability and readability are far more important in the majority of cases. However, considering micro-optimisation from time to time doesn't hurt. A basic understanding can help us not to make obvious bad choices when coding such as if (expensiveFunction() && counter < X) Should be if (counter < X && expensiveFunction()) (example from @zidarsk8) This could be an inexpensive function and therefore changing the code would be micro-optimisation. But, with a basic understanding, you would not have to because you would write it correctly in the first place.

• What types of programming contest problems are there?

  - by Alex

  Basically, I want to make a great reference for use with programming contests that would have all of the algorithms that I can put together that I would need during a contest as well as sample useage for the code. I'm planning on making this into a sort of book that I could print off and take with me to competitions. I would like to do this rather than simply bringing other books (such as Algorithms books) because I think that I will learn a lot more by going over all of the algorithms myself as well as I would know exactly what I have in the book, making it more efficient to have and use. So, I've been doing research to determine what types of programming problems and algorithms are common on contests, and the only thing I can really find is this (which I have seen referenced a few times): Hal Burch conducted an analysis over spring break of 1999 and made an amazing discovery: there are only 16 types of programming contest problems! Furthermore, the top several comprise almost 80% of the problems seen at the IOI. Here they are: Dynamic Programming Greedy Complete Search Flood Fill Shortest Path Recursive Search Techniques Minimum Spanning Tree Knapsack Computational Geometry Network Flow Eulerian Path Two-Dimensional Convex Hull BigNums Heuristic Search Approximate Search Ad Hoc Problems The most challenging problems are Combination Problems which involve a loop (combinations, subsets, etc.) around one of the above algorithms - or even a loop of one algorithm with another inside it. These seem extraordinarily tricky to get right, even though conceptually they are ``obvious''. Now that's good and all, but that study was conducted in 1999, which was 13 years ago! One thing I know is that there are no BigNums problems any more (as Java has a BigInteger class, they have stopped making those problems). So, I'm wondering if anyone knows of any more recent studies of the types of problems that may be seen in a programming contest? Or what the most helpful algorithms on contests would be?

• Would it be a good idea to work on letting people add arrays of numbers in javascript?

  - by OneThreeSeven

  I am a very mathematically oriented programmer, and I happen to be doing a lot of java script these days. I am really disappointed in the math aspects of javascript: the Math object is almost a joke because it has so few methods you can't use ^ for exponentiation the + operator is very limited, you cant add array's of numbers or do scalar multiplication on arrays Now I have written some pretty basic extensions to the Math object and have considered writing a library of advanced Math features, amazingly there doesn't seem to be any sort of standard library already out even for calculus, although there is one for vectors and matricies I was able find. The notation for working with vectors and matricies is really bad when you can't use the + operator on arrays, and you cant do scalar multiplication. For example, here is a hideous expression for subtracting two vectors, A - B: Math.vectorAddition(A,Math.scalarMultiplication(-1,B)); I have been looking for some kind of open-source project to contribute to for awhile, and even though my C++ is a bit rusty I would very much like to get into the code for V8 engine and extend the + operator to work on arrays, to get scalar multiplication to work, and possibly to get the ^ operator to work for exponentiation. These things would greatly enhance the utility of any mathematical javascript framework. I really don't know how to get involved in something like the V8 engine other than download the code and start working on it. Of course I'm afraid that since V8 is chrome specific, that without browser cross-compatibility a fundamental change of this type is likely to be rejected for V8. I was hoping someone could either tell me why this is a bad idea, or else give me some pointers about how to proceed at this point to get some kind of approval to add these features. Thanks!

• How much effort should you put into a junior developer?

  - by Crazy Eddie

  At what point should one give up? I've tried helping them out by having them shadow me. We agree to break a minute, and then they go missing in action for a while...then just go back to their desk. Even when I know they've done this, part of me feels like I shouldn't have to go get them but that they should be showing interest in learning. Frankly, it's a bunch of time I don't have explaining things as I go when I could just do it. Am I expecting too much to expect that if they want to learn they'll make sure I know they're ready and willing? They go to meetings that they where not told they had to, good, but then sit in the corner and sleep...bad. I don't even know what to do with that. Sometimes I give them something small to do and they do it great, so I give them something just a touch harder and they totally fail, hard. Check in things without testing them. Part of me thinks that maybe I should be spending more time with them but at the same time I don't see a lot of interest and I really, honestly don't have time teaching the same things over and over. Sometimes I get asked questions that are really, really easy to answer if you just do a little bit of your own work trying to find out. Other times I'm not asked anything. I'm sure I could be doing better but honestly...I don't really want to anymore.

• In agile environment, how is bug tracking and iteration tracking consolidated.

  - by DXM

  This topic stemmed from my other question about management-imposed waterfall-like schedule. From the responses in the other thread, I gathered this much about what is generally advised: Each story should be completed with no bugs. Story is not closed until all bugs have been addressed. No news there and I think we can all agree with this. If at a later date QA (or worse yet a customer) finds a bug, the report goes into a bug tracking database and also becomes a story which should be prioritized just like all other work. Does this sum up general handling of bugs in agile environment? If yes, the part I'm curious about is how do teams handle tracking in two different systems? (unless most teams don't have different systems). I've read a lot of advice (including Joel's blog) on software development in general and specifically on importance of a good bug tracking tool. At the same time when you read books on agile methodology, none of them seem to cover this topic because in "pure" agile, you finish iteration with no bugs. Feels like there's a hole there somewhere. So how do real teams operate? To track iterations you'd use (whiteboard, Rally...), to track bugs you'd use something from another set of products (if you are lucky enough, you might even get stuck with HP Quality Center). Should there be 2 separate systems? If they are separate, do teams spend time creating import/sync functionality between them? What have you done in your company? Is bug tracking software even used? Or do you just go straight to creating a story?

• Finally! Entity Framework working in fully disconnected N-tier web app

  - by oazabir

  Entity Framework was supposed to solve the problem of Linq to SQL, which requires endless hacks to make it work in n-tier world. Not only did Entity Framework solve none of the L2S problems, but also it made it even more difficult to use and hack it for n-tier scenarios. It’s somehow half way between a fully disconnected ORM and a fully connected ORM like Linq to SQL. Some useful features of Linq to SQL are gone – like automatic deferred loading. If you try to do simple select with join, insert, update, delete in a disconnected architecture, you will realize not only you need to make fundamental changes from the top layer to the very bottom layer, but also endless hacks in basic CRUD operations. I will show you in this article how I have  added custom CRUD functions on top of EF’s ObjectContext to make it finally work well in a fully disconnected N-tier web application (my open source Web 2.0 AJAX portal – Dropthings) and how I have produced a 100% unit testable fully n-tier compliant data access layerfollowing the repository pattern. http://www.codeproject.com/KB/linq/ef.aspx In .NET 4.0, most of the problems are solved, but not all. So, you should read this article even if you are coding in .NET 4.0. Moreover, there’s enough insight here to help you troubleshoot EF related problems. You might think “Why bother using EF when Linq to SQL is doing good enough for me.” Linq to SQL is not going to get any innovation from Microsoft anymore. Entity Framework is the future of persistence layer in .NET framework. All the innovations are happening in EF world only, which is frustrating. There’s a big jump on EF 4.0. So, you should plan to migrate your L2S projects to EF soon.

• Radeon HD 6850 VMware 3D Support?

  - by Matt

  I'm a new Ubuntu user (new to all of linux actually). I've installed Ubuntu 11.10 x64 and have been enjoying it, but I wanted to see how it would perform using VMware for small time gaming since I find dual booting too much of a nuisance to even bother using Ubuntu at all (sorry!). I have an Asus EAH6850 DirectCU Radeon HD 6850 graphics card and I've installed the additional ATI/AMD proprietary FGLRX graphics driver, but when I open a Windows XP 32bit machine I installed through VMware, I get this message: "The GPU driver currently installed on this host may cause issues with VMware products. If you notice any issues please disable the 3D support in the affected virtual machines." I still have 3D capabilities in the VM but they are very very choppy even running the DX tests (the spinning cube). I've seen people on youtube and other forums saying that since the new 3D acceleration in VMware 8 gaming is very possible through VMs (and I've seen them running the DX tests with the spinning cube very smoothly). I'm wondering if my graphics card isn't fully supported or if I have installed it wrong. Also when I check system info (on the host Ubuntu machine) it says "Graphics VESA:BARTS" Should my Radeon HD 6850 be showing up there? The rest of my basic system info i5 2500k 8GB 1600MHz memory Guest is running with access to all 4 cores of processor and 3gb memory assigned.

• Finding links among many written and spoken thoughts

  - by Peter Fren

  So... I am using a digital voice recorder to record anything I see important, ranging from business to private, from rants to new business ideas. Every finalized idea is one wma-file. I wrote a program to sort the wma-files into folders. From time to time I listen to the wma-files, convert them to text(manually) and insert them into a mindmap with mindmanager, which I sort hierarchically by area and type in turn. This works very well, no idea is being lost, when I am out of ideas for a special topic, I listen to what I said and can get started again. What could a search system look like that finds links between thoughts(written in the mindmap and in the wma files) or in general gives me good search results even when the keyword I searched for is not present but a synonym of it or related topic(for instance flower should output entries containing orchid aswell, even if they contain orchid but not the very keyword flower). I prefer something ready-made but small adjustments to a given system are fine aswell. How would you approach this task?

• Suddely internet is not accessible

  - by user189708

  I am going crazy here. One day everything was working fine. I turned pc off and went to sleep. Next day turn pc on and cannot access internet (from any browser). The situation is: I cannot open any webpage from browser (tried Firefox and Epiphany) and cannot receive emails in thunderbird. BUT if I run firefox from console as sudo, I can use it as usual. I can access Skype and pretty much any other network stuff (like installing software with apt-get etc.), also if I use Astrill VPN software I can access webpages even running without sudo. I haven't install any software or anything like that for several days = I have not a clue what could cause this. Just by the way, other Win PC in our home has no issue. Here is what I have tried to fix this: I have tried to restart my pc, router, modem - multiple times I have tried to change permissions to my firefox profile I have tried to completely re-install firefox and start with blank profile, thus no addons I have tried to change /etc/resolv.conf to an IP of my router (it was 127.0.1.1) I have tried to change my hostname (from tomino-NB to tominoNB) I think I might try even more stuff. None of it works. Can someone please try to help me. Thank you UPDATE 1: I have tried this: Removing resolv.conf - Didn't help Also "ping" and "dig" commands cannot resolve host UPDATE 2: I have tried to edit nameservers in resolv.conf but still no effect. I can ping router as well as I can ping outside IP. So definitely just some DNS issue. Is it possible that something is rewriting path to resolv.conf and using different file? UPDATE 3: I have just restarted PC and everything works now... resolv.conf went back to nameserver 127.0.1.1 . I have no clue what happened that it works again...

• NVIDIA proprietary driver logging me to console instead of GUI

  - by Woozie

  Firstly i want to apologise for any mistakes, English is not my native language. My problem is I can't get NVIDIA proprietary drivers to work. I tried to install it on Ubuntu 12.04.1 32 and 64 bits, Ubuntu 12.10 Beta 2, Linux Mint 13 Cinnamon 64 bits and openSUSE 12.2 64 bits and the error code and symptoms (logging to tty1 instead of GUI logging, low-res bootscreen) are the same for all of these distros. Right, I didn't tell what's the error code. It appears on sudo startx. NVIDIA: could not open the device file /dev/nvidia0 (Input/output error). I know that's the common problem, but I tried to blacklist or even remove the noveau drivers, install NVIDIA driver from repo/from official script/in "Additional drivers", editing xorg.conf and using Xorg -configurate and nvidia-xconfig, actualizing the kernel and entire distro and many, many things that I don't remember. But the problem is even better: entire Cinnamon (Mint) is freezing during the work. I found the error code, which appears during the freeze: Oct 1 20:57:17 WoozieLaptop kernel: [ 308.120176] [drm] nouveau 0000:01:00.0: PFIFO_CACHE_ERROR - Ch 4/1 Mthd 0z0060 Data 0xbcef0201 My Xorg.0.log is here. It was made on Ubuntu 12.04.1 after installing NVIDIA drivers (obviously). inxi -G from Mint: Graphics: Card: NVIDIA GT216 [GeForce GT 240M] X.org: 1.11.3 drivers: (unloaded: nvidia) FAILED: nouveau,vesa,fbdev tty size: 80x25 Advanced Data: N/A for root out of X lspci -k | grep -A2 VGA from Mint: 01:00.0 VGA compatible controller: NVIDIA Corporation GT216 [GeForce GT 240M] (rev a2) Subsystem: Lenovo Device 38ff Kernel driver in use: nvidia My hardware is: Lenovo IdeaPad Y550 Intel C2D T6600 NVIDIA GeForce GT 240M 4 GB of RAM Any help will be appreciated.

• Office design and layout for agile development

  - by Adam Eberbach

  (moved from stackoverflow) I have found lot of discussions here on about which keyboard, desk, light or colored background is best - but I can't find one addressing the layout of the whole office. We are a company with about 20 employees moving to a new place, something larger. There are two main development practices going on here with regular combination, the back end people often needing to work with the mobile people to arrange web services. There are about twice as many back end people as mobile people. About half of the back end developers are working on-site at any time and while they are almost never all in the office at once at least 5-10 spaces need to be provided - so most of the time the two groups are about equal. We have the chance to arrange desks, partitions and possibly even walls to make the space good. There won't be cash for dot-com frills like catering or massages but now's the time to be planning to avoid ending up with a bunch of desks in a long line. Joel on Software's Bionic Office is an article I've remembered from way back and it has some good ideas but I* (and more importantly the company's owners) are not completely sold on the privacy idea in an environment where we are supposed to be collaborating. This is another great link - The Ultimate Software Development Office Layout - I hadn't even remembered enclosed meeting rooms until reading this. Does the private office stand in the way of agile development? Is the scrum enough forced contact and if you need to bug someone you should need to get up and knock on their door? What design layouts can you point to and why would you recommend them? *I'm not against closed offices at all but would be happy if some other solution can do just as well. If it can't... well, that's what this question is all about.

• How do I remove a LOT of indexed pages from Google?

  - by Thierry

  A few weeks ago we have figured out that Google has indexed some information we would rather keep in some confidentiality, in the format of individual PDF files. Our assumption was that this was a problem with our robots.txt we had overlooked. Even though we are not sure whether or not this is the case, we are certain that the robots.txt file is in a valid format and is, according to Google's webmaster tools, blocking the files. However, even after this adjustment that has been made weeks ago, Google still has the PDF files indexed, but does tell us further information cannot be provided due to the robots.txt file being present. As you can hopefully understand, this is unwanted behaviour due to the nature of the documents. I am aware that there is a request page being provided by Google for this purpose, but there are a lot of files. Is there an easier way to get Google to remove all of the files from its search engine? If not, is there anything else you could advise us to do besides manually requesting Google to remove every single page? Thanks in advance.
