• How to improve Algorithmic Programming Solving skill? [closed]

  - by gaurav

  Possible Duplicate: How can I improve my problem-solving ability? How do you improve your problem solving skills? Should I learn design patterns or algorithms to improve my logical thinking skills? What to do when you're faced with a problem that you can't solve quickly? Are there non-programming related activities akin to solving programming problems? I am a computer engineering graduate. I have studied programming since three years. I am good in coding and programming. I have been trying to compete in algorithmic competitions on sites such as topcoder,spoj since one and a half year, but I am still unable to solve problems other than too easy problems. I have learned from people that it takes practice to solve such problems. I try to solve those problems but sometimes I am unable to understand and even if I do understand I am unable to think of a good algorithm for solving it. Even if I solve I get Wrong answer and I am unable to figure out what is the problem with my code as it works on samples given on the sites but fails on test cases which they do not provide. I really want to solve those problems and become good in algorithms. I have read books for learning algorithms like Introduction to algorithms by CLRS,practicing programming questions. I have gone through some questions but they don't answer this question. I have seen the questions which are said duplicates but those questions focus on overall programming, but I am asking for algorithm related programming, basically for competing in programming which involve solving a problem statement then online judge will automatically evaluate it, such type of programming is quite different from the type of programming these questions discuss.

• Single sign-on for SharePoint to MySite?

  - by Chris W

  I've got a fairly simple SharePoint 2010 farm set up: 2 WFE servers with Network Load Balancing hosting the main portal site. As per Microsoft's best practice recommendations I've set up My Sites in a separate web application. As some of the user base are not using domain joined PCs they have to login once for the portal (http://portal) and then again when the access My Sites since they're crossing in to a separate web application on a separate host (http://mysite). Portal & MySite are both hosted on the same physical WFE servers. Is there an easy way to set up some thing to stop this happening and just have them login once? I understand that there's plans for us to deploy ISA in the not too distant future - could we use ISA to manage authentication to the two sites so that the users only need to log in once?

• Lendle Connects Kindle Owners for Cross-Country Book Lending

  - by Jason Fitzpatrick

  You can lend books from your Kindle library to other Kindle users but it’s not always easy to find people with books you want. Lendle is a social network for Kindle readers to share books with each other. If you have a Kindle (the physical Kindle or the software on your smartphone or computer) you can easily lend books to other Kindle users. The problem is that there is no good way for you to easily find out what books your friends have. Furthermore your friends simply may not be into books that you’re into. Enter Lendle, a free service that connects Kindle users across the US (currently the Kindle lending program is limited to US customers) so that they can share books with each other. Your real life friends may not be into vampire romance, for example, but plenty of people on Lendle are and would be happy to loan you books. The only requirements for participation in the Lendle system are: Kindle ownership (either the physical or software-based Kindle) as books you’re willing to lend out. In addition to benefiting from other user’s libraries, Lendle also gives users a small credit when they lend a book–credits are redeemable as Amazon.com gift certificates. Hit up the link below to read more and sign up for a free Lendle account.

• Distinct operator in Linq

  - by Jalpesh P. Vadgama

  Linq operator provides great flexibility and easy way of coding. Let’s again take one more example of distinct operator. As name suggest it will find the distinct elements from IEnumerable. Let’s take an example of array in console application and then we will again print array to see is it working or not. Below is the code for that. In this application I have integer array which contains duplicate elements and then I will apply distinct operator to this and then I will print again result of distinct operators to actually see whether its working or not. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Experiment { class Program { static void Main(string[] args) { int[] intArray = { 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5 }; var uniqueIntegers = intArray.Distinct(); foreach (var uInteger in uniqueIntegers) { Console.WriteLine(uInteger); } Console.ReadKey(); } } } Below is output as expected.. That’s cool..Stay tuned for more.. Happy programming. Technorati Tags: Linq,Distinct

• Domains with similar names and legal issues

  - by abel

  I recently purchased one of those domain names like del.icio.us. While registering I found that delicious.com was being used. Argument: I found that delicious.com belonged to the same category as my to-be website. It served premium delicious dishes. Counter Argument: My to-be domain though belonging to the same category, specialized in serving free but delicious dishes or in giving out links(affiliate) to other sites serving premium delicious dishes. Additional Counter Arguments: 1.delicious.com was not in English. 2.the del.icio.us in my domain name though having the same spelling, is not going to be used in the same fashion. For eg.(this may not make sense, because the names have been changed)the d in delicious on my website actually stands for the greek letter Delta(?/d) and since internationalized domains are still not easily typable, I am going for the english equivalent.The prefix holds importance for the theme of the service which my website intends to offer. My Question: Can I use the domain name del.icio.us for my website? How are these kinds of matters dealt? (The domain names used are fictitious. And I have already registered the domain but have not started using it.I chanced upon this domain name because it was short, easy to remember and suited the theme of my website.)

• What would cause Google Music Manager to report different amounts of music between iTunes and My Music?

  - by Thomas Owens

  If I set Google Music Manager to scan iTunes, it reports that there are 3997 songs (which is also indicated if I were to open iTunes and look at my collection). However, if set Google Music Manager to scan My Music folder, it detects 3999 songs. I even deleted all of my songs from iTunes and reimported my My Music folder. iTunes is still reporting 3997 songs. Is there an easy way to find out what is causing the difference between the two counts? I could probably add all of my songs to a playlist, export the playlist into a text or XML file using iTunes, and compare that list against everything in My Music folder to see if iTunes is missing music. However, I was wondering if anyone could shed some light on this before I did that...

• Why do some programmers think there is a contrast between theory and practice?

  - by Giorgio

  Comparing software engineering with civil engineering, I was surprised to observe a different way of thinking: any civil engineer knows that if you want to build a small hut in the garden you can just get the materials and go build it whereas if you want to build a 10-storey house you need to do quite some maths to be sure that it won't fall apart. In contrast, speaking with some programmers or reading blogs or forums I often find a wide-spread opinion that can be formulated more or less as follows: theory and formal methods are for mathematicians / scientists while programming is more about getting things done. What is normally implied here is that programming is something very practical and that even though formal methods, mathematics, algorithm theory, clean / coherent programming languages, etc, may be interesting topics, they are often not needed if all one wants is to get things done. According to my experience, I would say that while you do not need much theory to put together a 100-line script (the hut), in order to develop a complex application (the 10-storey building) you need a structured design, well-defined methods, a good programming language, good text books where you can look up algorithms, etc. So IMO (the right amount of) theory is one of the tools for getting things done. So my question is why do some programmers think that there is a contrast between theory (formal methods) and practice (getting things done)? Is software engineering (building software) perceived by many as easy compared to, say, civil engineering (building houses)? Or are these two disciplines really different (apart from mission-critical software, software failure is much more acceptable than building failure)?

• Logitech gamepad f710 and ubuntu and as an input to a python program

  - by wherestheforce

  I would like to use the Logitech F710 gamepad as an input device to a python program. I am using Ubuntu. I do not really know where to start, so here are a few questions: How does Ubuntu detect the gamepad? If the gamepad is recognized within Ubuntu, how would I interact with this device via a python script? If this is not easy to do in Ubuntu, how would I interact with the gamepad via a python script in Windows? Thanks!

• Frustum culling with third person camera

  - by Christian Frantz

  I have a third person camera that contains two matrices: view and projection, and two Vector3's: camPosition and camTarget. I've read up on frustum culling and it makes it seem easy enough for a first person camera, but how would I implement this for a third person camera? I need to take into effect the objects I can see behind me too. How would I implement this into my camera class so it runs at the same time as my update method? public void CameraUpdate(Matrix objectToFollow) { camPosition = objectToFollow.Translation + (objectToFollow.Backward *backward) + (objectToFollow.Up * up); camTarget = objectToFollow.Translation; view = Matrix.CreateLookAt(camPosition, camTarget, Vector3.Up); } Can I just create another method within the class which creates a bounding sphere with a value from my camera and then uses the culling based on that? And if so, which value am I using to create the bounding sphere from? After this is implemented, I'm planning on using occlusion culling for the faces of my objects adjacent to other objects. Will using just one or the other make a difference? Or will both of them be better? I'm trying to keep my framerate as high as possible

• SQL SERVER 2008 – 2011 – Declare and Assign Variable in Single Statement

  - by pinaldave

  Many of us are tend to overlook simple things even if we are capable of doing complex work. In SQL Server 2008, inline variable assignment is available. This feature exists from last 3 years, but I hardly see its utilization. One of the common arguments was that as the project migrated from the earlier version, the feature disappears. I totally accept this argument and acknowledge it. However, my point is that this new feature should be used in all the new coding – what is your opinion? The code which we used in SQL Server 2005 and the earlier version is as follows: DECLARE @iVariable INT, @vVariable VARCHAR(100), @dDateTime DATETIME SET @iVariable = 1 SET @vVariable = 'myvar' SET @dDateTime = GETDATE() SELECT @iVariable iVar, @vVariable vVar, @dDateTime dDT GO The same should be re-written as following: DECLARE @iVariable INT = 1, @vVariable VARCHAR(100) = 'myvar', @dDateTime DATETIME = GETDATE() SELECT @iVariable iVar, @vVariable vVar, @dDateTime dDT GO I have started to use this new method to assign variables as I personally find it very easy to read as well write. Do you still use the earlier method to declare and assign variables? If yes, is there any particular reason or just an old routine? I am interested to hear about this.

• Adding a CMS to an existing Magento shop

  - by user6341

  I am working on a project for 3 niche stores built on magento (using magento's multi-store function) that each get roughly 50k unique visitors a day. The sites don't currently have a blog or forum or any social networking aspects. Would like to add a cms to each site that can be centrally run and would like it to take over the front end content from Magento. Also would like it to maintain an online blog/publication of sorts with videos, articles, and the like with privileges to edit the content given to a dozen or so people with different privileges. Want to add a forum to each site that is fairly robust and to possibly add some social networking aspects down the road, so extandability and available plugins/mods in each cms is important. Other than shared login between the forums,blog/publication and store, would like to be able to integrate some content from the forums and blog/publication into the store as well. After researching this a bit, I am inclined towards Drupal, but I haven't found any modules to integrate it with Magento. Also, since the blog content will be done by about a dozen nontechnical people, I want something that is very easy to work with. Lastly, since the site gets a good amount of traffic, speed and security are very important. What CMS would you recommend integrating in this context? Deciding between Drupal, Wordpress and Plone. Thanks.

• Installing ethernet drivers with no install package

  - by Josh

  I recently got my new Sony Vaio laptop and formatted it into Windows 7 Ultimate. I would like to use the Windows Easy Transfer Tool over a network connection to transfer some of my files over from my desktop PC. Before I do this though, I need to install the ethernet LAN drivers (I'm currently using the built in Wifi). I downloaded the original LAN driver that came with my Vaio originally from the Sony website: http://support.vaio.sony.eu/computing/vaio/downloads/preinstalled/index.aspx?l=en_GB&m=VPCEB1Z0E_B [Scroll down to the 450KB Ethernet driver] When I unzip the package, these files are inside: yk62x64.cat yk62x64.dll yk62x64.inf yk62x64.sys As you can see, no installer. Can anyone guide me through how to properly install these drivers? I have thought of using Google but I'm clueless as to what query to use. Thanks.

• Delete file then run file at startup

  - by Henry Gibson

  I'm running the music player Foobar2000 through Wine at startup. For some reason when I shutdown Ubuntu the Foobar2000 process is ended abnormally in Wine and when it runs next time I get an annoying "start in safe mode?" message. Not a huge problem, but I'd like it fixed. The safe mode message only appears if a file called "running" is present when Foobar2000 starts (if it isn't deleted when closed properly). So by deleting "running" then starting Foobar2000, the message doesn't appear. I thought it would be easy enough to enter this as a startup command, however it doesn't want to work. The command I am using is rm '/home/henry/.wine/drive_c/users/henry/Application Data/foobar2000/running';'/home/henry/.wine/drive_c/Program Files (x86)/foobar2000/foobar2000.exe' which works fine if I just run it from terminal, the file is deleted then foobar2000 runs. Does anyone know why this isn't working at startup? Also, will this run with a terminal visible? How can I make just the gui appear? Thanks

• Computer Bugs - Etymology and Entomology

  - by PointsToShare

  Whatever bugs you My wife and I used to take some of our summer vacation I a cabin on the shore of Lake Atsion in NJ. I t is a delightful place in the Wharton forest with Brown yet fresh water, where we would canoe, swim and enjoy true rest. Alas, in the last few years, yellow flies also discovered the area’s pastoral delights and came in hoards to bug us. So much so that we had to give up. As a computer programmer I abhor bugs. The bugs that bug me – except the pesky yellow flies – are program bugs , a specific variety of computer bugs. You can find an excellent take on the etymology of the word ‘bug” in this delightful monogram: http://www.jamesshuggins.com/h/tek1/first_computer_bug.htm In my youth, I worked on Burroughs computers. Unlike their IBM brethren, the Burroughs used a 96 column card. The cards were much smaller than the 80 column IBM cards. We wrote our programs on coding sheets and then a key-punch operator transcribed them into punched cards. These were fed into a card reader and compiled. The compiler would notify us of compiler errors or bugs, but it was not always easy to get the meaning of the message. My friend Mark Wildt, also a Burroughs veteran, gave me an old punched card from one of his programs. Obviously a bug!! Here It Is!! That’s All Folks!

Could it break any applications? Similar question: Resolving dependencies related to 32 bit libraries on 64 bit

• Disabling file permissions on NFS share

  - by user41377

  I am trying to set up a nfs share for use by non-technical users, and really don't want file permissions messing things up. Everyone should be able to read/write anything on this share without even knowing what file permissions are, much less adjusting them. Is there a way I can just make the nfs server write everything as 770 or something? It seems like this should be easy, but the best I can come up with is a cronjob to periodically set them to that, which is far from ideal. The server is a Netgear ReadyNAS. Ideally I would like to stick to doing stuff from within the web interface on it, but I can just root it if needed.

• Can't boot into windows7/ubuntu 12.04 after running boot-repair

  - by Rini

  I have installed Ubuntu 12.04 on my preinstalled windows 7 Sony vaio E series laptop following instructions here: http://www.linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/ Everything went well and I am able to boot in to windows after complete installation of Ubuntu. Now following instructions on web I tried to add Ubuntu to my BIOS using Easy BCD (but forget to add windows 7 entry). As a result, I loose windows 7 OS and can't boot in to either OS then I successfully repaired windows 7 using recovery CD. Now my problem is that I can't reinstall Ubuntu 12.04 using Live CD it halts every time before disk partition step giving error. "ubi-partman crashed". "ubi-partman failed with exit code 141. further information may be found in /var/log/syslog. Do you want to try running this step again before continuing? If you do not, your installation may fail entirely or may be broken." and, any choice to continue will result in the same error. After that following some post solutions I ran boot-repair commands in terminal ( in Try Ubuntu mode) and got the following URL: http://paste.ubuntu.com/1206434/ Now, after restart I can't boot into either Windows or Ubuntu. Even any attempt to run Windows repair is failed and I got the message : 'No operating System found' I don't know what went wrong after running boot-repair command. Please help in solving this issue. Thanks and Regards, R Shukla

• Linux to Solaris @ Morgan Stanley

  - by mgerdts

  I came across this blog entry and the accompanying presentation by Robert Milkoski about his experience switching from Linux to Oracle Solaris 11 for a distributed OpenAFS file serving environment at Morgan Stanley. If you are an IT manager, the presentation will show you: Running Solaris with a support contract can cost less than running Linux (even without a support contract) because of technical advantages of Solaris. IT departments can benefit from hiring computer scientists into Systems Programmer or similar roles.  Their computer science background should be nurtured so that they can continue to deliver value (savings and opportunity) to the business as technology advances. If you are a sysadmin, developer, or somewhere in between, the presentation will show you: A presentation that explains your technical analysis can be very influential. Learning and using the non-default options of an OS can make all the difference as to whether one OS is better suited than another.  For example, see the graphs on slides 3 - 5.  The ZFS default is to not use compression. When trying to convince those that hold the purse strings that your technical direction should be taken, the financial impact can be the part that closes the deal.  See slides 6, 9, and 10.  Sometimes reducing rack space requirements can be the biggest impact because it may stave off or completely eliminate the need for facilities growth. DTrace can be used to shine light on performance problems that may be suspected but not diagnosed.  It is quite likely that these problems have existed in OpenAFS for a decade or more.  DTrace made diagnosis possible. DTrace can be used to create performance analysis tools without modifying the source of software that is under analysis.  See slides 29 - 32. Microstate accounting, visible in the prstat output on slide 37 can be used to quickly draw focus to problem areas that affect CPU saturation.  Note that prstat without -m gives a time-decayed moving average that is not nearly as useful. Instruction level probes (slides 33 - 34) are a super-easy way to identify which part of a function is hot.

• How should I unbind and delete OpenAL buffers?

  - by Joe Wreschnig

  I'm using OpenAL to play sounds. I'm trying to implement a fire-and-forget play function that takes a buffer ID and assigns it to a source from a pool I have previously allocated, and plays it. However, there is a problem with object lifetimes. In OpenGL, delete functions either automatically unbind things (e.g. textures), or automatically deletes the thing when it eventually is unbound (e.g. shaders) and so it's usually easy to manage deletion. However alDeleteBuffers instead simply fails with AL_INVALID_OPERATION if the buffer is still bound to a source. Is there an idiomatic way to "delete" OpenAL buffers that allows them to finish playing, and then automatically unbinds and really them? Do I need to tie buffer management more deeply into the source pool (e.g. deleting a buffer requires checking all the allocated sources also)? Similarly, is there an idiomatic way to unbind (but not delete) buffers when they are finished playing? It would be nice if, when I was looking for a free source, I only needed to see if a buffer was attached at all and not bother checking the source state. (I'm using C++, although approaches for C are also fine. Approaches assuming a GCd language and using finalizers are probably not applicable.)

• WPA Enterprise Wireless Bridge

  - by prestomation

  I live in college housing at a university with wifi available. unfortunately, my bedroom(where I'd like to place my PC) gets little to no reception. I'd like to place a router in the strongest spot and rebroadcast. I understand this can be done with DD-WRT/etc, but this particular network is WPA Enterprise with my own personal username/password. I can't find any concrete evidence that I can get my router to act as a repeater for this encryption. I don't currently have a router to test it on, otherwise this would be easy, I just don't want to buy a router if it will be worthless to me. Thanks for your help

• isometric drawing order with larger than single tile images - drawing order algorithm?

  - by Roger Smith

  I have an isometric map over which I place various images. Most images will fit over a single tile, but some images are slightly larger. For example, I have a bed of size 2x3 tiles. This creates a problem when drawing my objects to the screen as I get some tiles erroneously overlapping other tiles. The two solutions that I know of are either splitting the image into 1x1 tile segments or implementing my own draw order algorithm, for example by assigning each image a number. The image with number 1 is drawn first, then 2, 3 etc. Does anyone have advice on what I should do? It seems to me like splitting an isometric image is very non obvious. How do you decide which parts of the image are 'in' a particular tile? I can't afford to split up all of my images manually either. The draw order algorithm seems like a nicer choice but I am not sure if it's going to be easy to implement. I can't solve, in my head, how to deal with situations whereby you change the index of one image, which causes a knock on effect to many other images. If anyone has an resources/tutorials on this I would be most grateful.

• Cloning Windows 7 installation from MBR to GPR drive and make it bootable

  - by Nelluk

  I've seen threads on similar topics - such as this one - but the answers never seem to solve how to make it bootable. I have Win 7 64-bit on a PC installed on a 2tb MBR volume. The motherboard is UEFI compatible. I just installed a secondary internal 3TB drive which will be partitioned as GPT. Is there a relatively easy way to clone my installation over to the new drive and have that drive be bootable? I have used EaseUS Partition Master to clone the C volume to the D volume, but that would not boot and I assume the issue is that one is MBR and one is GPT. Is there a process to do this?
