• Shuffling algorithm with no "self-mapping"?

  - by OregonTrail

  To randomly shuffle an array, with no bias towards any particular permutation, there is the Knuth Fischer-Yeats algorithm. In Python: #!/usr/bin/env python import sys from random import randrange def KFYShuffle(items): i = len(items) - 1 while i > 0: j = randrange(i+1) # 0 <= j <= i items[j], items[i] = items[i], items[j] i = i - 1 return items print KFYShuffle(range(int(sys.argv[1]))) There is also Sattolo's algorithm, which produces random cycles. In Python: #!/usr/bin/env python import sys from random import randrange def SattoloShuffle(items): i = len(items) while i > 1: i = i - 1 j = randrange(i) # 0 <= j <= i-1 items[j], items[i] = items[i], items[j] return items print SattoloShuffle(range(int(sys.argv[1]))) I'm currently writing a simulation with the following specifications for a shuffling algorithm: The algorithm is unbiased. If a true random number generator was used, no permutation would be more likely than any other. No number ends up at its original index. The input to the shuffle will always be A[i] = i for i from 0 to N-1 Permutations are produced that are not cycles, but still meet specification 2. The cycles produced by Sattolo's algorithm meet specification 2, but not specification 1 or 3. I've been working at creating an algorithm that meets these specifications, what I came up with was equivalent to Sattolo's algorithm. Does anyone have an algorithm for this problem?

• Hostname Problem On WHM / cPanel Installation

  - by Eray

  My CentOS 5.6 server's hostname was "centos" . And then i change it to my domain : hostname domain.com And i started to installing WHM / cPanel as explained in here : http://etwiki.cpanel.net/twiki/bin/view/AllDocumentation/InstallationGuide/InstallingCpanel It's installed very well. And the i reboot my server. After rebooting, i was execute this command for open WHM's 2087 port : iptables -I RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 2087 -j ACCEPT Now i'm trying to browse domain.com:2087 i'm getting Server (centos) not found .I noticed it's forwarding to my old hostname (centos) . And then execute this command to verify me hostname hostname it's returned "centos" again. I'm not sure, why it's returned to old hostname. (I think it returned to old hostname after rebooting) . I'm changed it one more time : hostname domain.com Finally, now my hostname is domain.com . BUt still i'm getting centos server not found error. This is result of iptables -L command. P.S. : domain.com/cpanel is working

• Top 5 Sites and Activities in San Francisco to Experience During Oracle OpenWorld

  - by kgee

  While Oracle OpenWorld may provide solutions and information on topics like how to simplify your IT, the importance of cloud, and what types of storage may satisfy your enterprise needs, who is going to tell you more about San Francisco? Here are some suggested sites and activities to experience after OpenWorld that aren’t too far from the Moscone Center. It is recommended to take a cab for the sake of time, but the 6 square miles that make up San Francisco will make for a quick trek to any of the following destinations: The Golden Gate BridgeAn image often associated with San Francisco, this bridge is one of the most impressive in the world. Take a walk across it, or view it from nearby Crissy Field, it is a sight that floors even the most veteran of San Franciscans. The Ferry BuildingLocated at the end of Market Street in the Embarcadero, the Ferry Building once served as a hub of water transport and trade. The building has a bay front view and an array of food choices and restaurants. It is easily accessible via the Muni, BART, trolley or by cab. It is a must-see in San Francisco, and not too far from the Moscone Center. Ride the Trolley to the CastroFor only $2, you can get go back in history for a moment on the Trolley. Take the F-line from the Embarcadero and ride it all the way to the Castro district. During the ride, you will get an overview of the landscape and cultures that are prevalent in San Francisco, but be wary that some areas may beg for an open mind more than others. Golden Gate ParkWhen you tire of the concrete jungle, the lucky part of being in San Francisco is that you can escape to a natural refuge, this park being one of the favorites. This park is known for its hiking trails, cultural attractions, monuments, lakes and gardens. It is one good reason to bring your sneakers to San Francisco, and is also a great place to picnic. Please be wary that it is easy to get lost, and it is advisable to bring a map (just in case) if you go. Haight AshburyFor a complete change of scenery, Haight Ashbury is known as one of the places hippies used to live and the location of "The Summer of Love." It is now a more affluent neighborhood with boutique shops and the occasional drum circle. While it may be perceived as grungy in certain spots, it is one of the most photographed places in San Francisco and an integral part of San Franciscan history.

• High-Level Application Architecture Question

  - by Jesse Bunch

  So I'm really wanting to improve how I architect the software I code. I want to focus on maintainability and clean code. As you might guess, I've been reading a lot of resources on this topic and all it's doing is making it harder for me to settle on an architecture because I can never tell if my design is the one that the more experienced programmer would've chosen. So I have these requirements: I should connect to one vendor and download form submissions from their API. We'll call them the CompanyA. I should then map those submissions to a schema fit for submitting to another vendor for integration with the email service provider. We'll call them the CompanyB. I should then submit those responses to the ESP (CompanyB) and then instruct the ESP to send that submitter an email. So basically, I'm copying data from one web service to another and then performing an action at the latter web service. I've identified a couple high-level services: The service that downloads data from CompanyA. I called this the CompanyAIntegrator. The service that submits the data to CompanyB. I called this CompanyBIntegrator. So my questions are these: Is this a good design? I've tried to separate the concerns and am planning to use the facade pattern to make the integrators interchangeable if the vendors change in the future. Are my naming conventions accurate and meaningful to you (who knows nothing specific of the project)? Now that I have these services, where should I do the work of taking output from the CompanyAIntegrator and getting it in the format for input to the CompanyBIntegrator? Is this OK to be done in main()? Do you have any general pointers on how you'd code something like this? I imagine this scenario is common to us engineers---especially those working in agencies. Thanks for any help you can give. Learning how to architect well is really mind-cluttering.

• how to think like a computer scientist java edition exercise 7.2 [on hold]

  - by James Canfield

  I cannot figure out how to write this program, can someone please help me?! The purpose of this method is to practice manipulating St rings. Create a new program called Name.java. This program will take a name string consisting of EITHER a first name followed by a last name (nonstandar d format) or a last name followed by a comma then a first name (standard format). Ie . “Joe Smith” vs. “Smith, Joe”. This program will convert the string to standard format if it is not already in standard format. Write a method called hasComma that takes a name as an argument and that returns a boolean indicating whether it contains a comma. If i t does, you can assume that it is in last name first format. You can use the indexOf String m ethod to help you. Write a method called convertName that takes a name as an argument. It should check whether it contains a comma by calling your hasComma method. If it does, it should just return the string. If not, then it should assume th at the name is in first name first format, and it should return a new string that contains the name converted to last name comma first format. Uses charAt, length, substring, and indexOf methods. In your main program, loop, asking the user for a n ame string. If the string is not blank, call convertName and print the results. The loop terminat es when the string is blank. HINTS/SUGGESTIONS: Use the charAt, length, substring, and indexOf Str ing methods. Use scanner for your input. To get the full line, complete with spaces, use reader.nextLine()

• Stereo images rectification and disparity: which algorithms?

  - by alessandro.francesconi

  I'm trying to figure out what are currently the two most efficent algorithms that permit, starting from a L/R pair of stereo images created using a traditional camera (so affected by some epipolar lines misalignment), to produce a pair of adjusted images plus their depth information by looking at their disparity. Actually I've found lots of papers about these two methods, like: "Computing Rectifying Homographies for Stereo Vision" (Zhang - seems one of the best for rectification only) "Three-step image recti?cation" (Monasse) "Rectification and Disparity" (slideshow by Navab) "A fast area-based stereo matching algorithm" (Di Stefano - seems a bit inaccurate) "Computing Visual Correspondence with Occlusions via Graph Cuts" (Kolmogorov - this one produces a very good disparity map, with also occlusion informations, but is it efficient?) "Dense Disparity Map Estimation Respecting Image Discontinuities" (Alvarez - toooo long for a first review) Anyone could please give me some advices for orienting into this wide topic? What kind of algorithm/method should I treat first, considering that I'll work on a very simple input: a pair of left and right images and nothing else, no more information (some papers are based on additional, pre-taken, calibration infos)? Speaking about working implementations, the only interesting results I've seen so far belongs to this piece of software, but only for automatic rectification, not disparity: http://stereo.jpn.org/eng/stphmkr/index.html I tried the "auto-adjustment" feature and seems really effective. Too bad there is no source code...

• Rotating object along bezier curve: not rotating enough?

  - by Paul

  I tried to follow the instructions from the threads on the forum (Cocos2d rotating sprite while moving with CCBezierBy) with Unity, in order to rotate my object as it moves along a bezier curve. But it does not rotate enough, the angle is too low, it goes up to 6 instead of 90 for example, as you can see on this image (the y eulerAngle is at 6, I would expect it to be around 90 with this curve) : Would you know why it does this? And how to make the rotation toward the next point? Here is the code (in c# with Unity) : (I am comparing x and z to get the angle, and adding the angle to eulerAngles.y so that it rotates around the y axis) void Update () { if ( Input.GetKey("d") ) start = true; if ( start ){ myTime = Time.time; start = false; } float theTime = (Time.time - myTime) *0.5f; if ( theTime < 1 ) { car.position = Spline.Interp( myArray, theTime );//creates the bezier curve counterBezier += Time.deltaTime; //compare 2 positions after 0.1f if ( counterBezier > 0.1f ){ counterBezier = 0; cbDone = false; newpos = car.position; float angle = Mathf.Atan2(newpos.z - oldpos.z, newpos.x - oldpos.x); angle += car.eulerAngles.y; car.eulerAngles = new Vector3(0,angle,0); } else if ( counterBezier > 0 && !cbDone ){ oldpos = car.position; cbDone = true; } Thanks

• Is an ACPI GPE storm normal in an Ubuntu session?

  - by Tinellus

  In a previous question (What is a an ACPI GPE storm?), I asked about ACPI GPE storm. Looking closer to my kern.log file in /var/log/, I notice that in every session at some point (usually withing 20' after startup) a GPE storm is triggered. When I open kern.log immediately after startup, I see that the 'GPE-storm' can be triggered by anything (a copy-action, the opening of an app like Firefox or Thunderbird, etc...). This worries me. Looking for other ACPI related events in kern.log, I find these error messages. I hope someone can give some advice: Jun 10 16:33:20 Guy-VAIO kernel: [ 0.724505] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it Jun 10 16:33:20 Guy-VAIO kernel: [ 0.795205] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored Jun 10 16:33:20 Guy-VAIO kernel: [ 1.024009] ACPI: Deprecated procfs I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared Jun 10 16:33:20 Guy-VAIO kernel: [ 23.140259] [Firmware Bug]: ACPI(VGA) defines _DOD but not _DOS There's also a video driver message that worries me, don't know if it's related though: Jun 10 16:33:20 Guy-VAIO kernel: [ 23.162154] fglrx: module license 'Proprietary.

• SharePoint 2010 search crawl not working

  - by J. Hammond

  I have the following set up: 1 x Windows server 2008 R2 running SQL 1 x Windows server 2008 R2 running SharePoint 2010. I have an issue with the search service application, the crawl appears to run for a never ending amount of time with 0 successes and 0 failures. Checking the Search Application Topology, I find that "Query Component 0" is "Not Responding". I have tried the following: I have ensured that the index directory has the right permissions applied to it and the search service account is in the right groups to consume those permissions. I have re-created the search service application. I have restarted the search service manually. I have trawled the net as much as possible to find a solution but as of yet have not come across something that has resolved this issue. Any input will be very much appreciated

• Hanging page loads every n loads

  - by Christian

  Hi Guys I recently moved my site to a new server (Apache 2, PHP5, MySQL5). The site is an Invision based forum. Every few posts / topics it just hangs. The data has been written because if you stop and reload, the post / thread is there. I thought it was a write issue initially, but nope. So, the data is written but the page load never completes. It doesn't leave the page where the data has been input. Whats the best way to trouble shoot this issue? The only thing I have done recently is reduce my MySQL timeouts, but I can't see that being an issue as the values are still big enough and there are no mentions of timeouts in the MySQL log. (For the record there is nothing in PHP's error log either) Thanks in advance!

• Proper way to let user enter password for a bash script using only the GUI (with the terminal hidden)

  - by MountainX

  I have made a bash script that uses kdialog exclusively for interacting with the user. It is launched from a ".desktop" file so the user never sees the terminal. It looks 100% like a GUI app (even though it is just a bash script). It runs in KDE only (Kubuntu 12.04). My only problem is handling password input securely and conveniently. I can't find a satisfactory solution. The script was designed to be run as a normal user and to prompt for the password when a sudo command is first needed. In this way, most commands, those not requiring sudo rights, are run as the normal user. What happens (when the script is run from the terminal) is that the user is prompted for their password once and the default sudo timeout allows the script to finish, including any additional sudo commands, without prompting the user again. This is how I want it to work when run behind the GUI too. The main problem is that using kdesudo to launch my script, which is the standard GUI way, means that the entire script is executed by the root user. So file ownerships get assigned to the root user, I can't rely upon ~/ in paths, and many other things are less than ideal. Running the entire script as the root user is just a very unsatisfactory solution and I think it is a bad practice. I appreciate any ideas for letting a user enter the sudo password just once via GUI while not running the whole script as root. Thanks.

• openQRM nagios password reset

  - by Entity_Razer

  Right so, basically the story is that to test a XenServer environment from citrix I deployed a openQRM install from SVN to a ubuntu 10.4 install (on a ESX Environment) All went well installs, I can connect to it, but I can't seem to access the nagios plug in. Every time i wish to go to it i'm asked for a pw, and if I input the pw I wrote down yesterday it just doesn't let me in. I'm trying to reset the password on the nagios plug in now but for the life of me can't find it. Googled high and low for a defenitive working solution but so far no luck. Anyone able to lend a hand ? Cheers ! Ubuntu 10.4 Beta as openQRM openQRM installed from SVN cheers

• How to implement early exit / return in Haskell?

  - by Giorgio

  I am porting a Java application to Haskell. The main method of the Java application follows the pattern: public static void main(String [] args) { if (args.length == 0) { System.out.println("Invalid number of arguments."); System.exit(1); } SomeDataType d = getData(arg[0]); if (!dataOk(d)) { System.out.println("Could not read input data."); System.exit(1); } SomeDataType r = processData(d); if (!resultOk(r)) { System.out.println("Processing failed."); System.exit(1); } ... } So I have different steps and after each step I can either exit with an error code, or continue to the following step. My attempt at porting this to Haskell goes as follows: main :: IO () main = do a <- getArgs if ((length args) == 0) then do putStrLn "Invalid number of arguments." exitWith (ExitFailure 1) else do -- The rest of the main function goes here. With this solution, I will have lots of nested if-then-else (one for each exit point of the original Java code). Is there a more elegant / idiomatic way of implementing this pattern in Haskell? In general, what is a Haskell idiomatic way to implement an early exit / return as used in an imperative language like Java?

• How to fix issue with my 3D first person camera?

  - by dxCUDA

  My camera moves and rotates, but relative to the worlds origin, instead of the players. I am having difficulty rotating the camera and then translating the camera in the direction relative to the camera facing angle. I have been able to translate the camera and rotate relative to the players origin, but not then rotate and translate in the direction relative to the cameras facing direction.

• Macbook Pro 13" Retina (10,2): Keyboard and Touchpad don't work

  - by Dirk

  I'm dealing with Ubuntu since about 5 years and installed it on several laptops. Now I'm stuck when trying to install Ubuntu 12.04.1 on a brand new Macbook Pro 13" Retina (10,2). I sucessfully can start Ubuntu from an USB stick, the Ubuntu desktop is visible, a mouse cursor is visible. But there is no respond to keyboard or touchpad input. So I cannot really install Ubuntu on the Macbook. The details of my approach: Prepare an empty USB stick Download "ISO 2 USB EFI Booter for Mac" and copy the file bootX64.efi to the USB drive as /efi/boot/bootX64.efi. Download Ubuntu 12.04.1 Desktop for Mac from http://cdimage.ubuntu.com/releases/1-amd64+mac.iso and copy the iso the USB drive as /efi/boot/boot.iso Put the USB stick into the Macbook Press and hold the "alt" button while switching the Macbook on Select "EFI Boot" from the boot menu that appears and press the Return / Enter key Immediately a black terminal screen appears with the headline "Welcome to the Ubuntu ISO << - EFI booter". 30 seconds later the familiar Ubuntu startup graphics screen is showing. Further 20 seconds later Ubuntu has started and the desktop is visible - in wonderfully fine resolution Now the computer does not respond to any actions on the touchpad nor the keyboard Who did install Ubuntu on this Macbook Pro 13" Retina (10,2) successfully? On this site https://help.ubuntu.com/community/MacBookPro this unit is not listed yet, anyway. Any help would be greatly appreciated! Dirk

• Connect a 2.5" (laptop hard disk) SATA hard disk to Desktop PC

  - by Lawliet

  Can I connect a laptop SATA hard disk to Desktop PC? Do I have to use some adapters or I can just plug in SATA power connector and SATA data cable like my Desktop hard disk is connected? I noticed that both laptop and desktop SATA disks use same connectors, but I'm afraid that I might fry my laptop hard disk because the SATA connector has both 12V and 5V voltage (given the fact that laptop hard disks has input voltage of 5V) I bought a all-in-one Modex-to-SATA power adapter and SATA cable and I still don't know what to do. I have read various forums and a lot of people are stating that it's perfectly ok, but some are scaring me that by connecting it so, it fried their hard disk. And some also mentioned cutting the yellow 12V wire if I'm planning to use Modex-to-SATA power. Thanks in advance

  Let's say you have an input file with many entries like these: date, ticker, open, high, low, close, <and some other values> And you want to execute a pattern matching routine on the entries(rows) in that file, using a candlestick pattern, for example. (See, Doji) And that pattern can appear on any uniform time interval (let t = 1s, 5s, 10s, 1d, 7d, 2w, 2y, and so on...). Say a pattern matching routine can take an arbitrary number of rows to perform an analysis and contain an arbitrary number of subpatterns. In other words, some patterns may require 4 entries to operate on. Say also that the routine (may) later have to find and classify extrema (local and global maxima and minima as well as inflection points) for the ticker over a closed interval, for example, you could say that a cubic function (x^3) has the extrema on the interval [-1, 1]. (See link) What would be the most natural choice in terms of a data structure? What about an interface that conforms a Ticker object containing one row of data to a collection of Ticker so that an arbitrary pattern can be applied to the data. What's the first thing that comes to mind? I chose a doubly-linked circular linked list that has the following methods: push_front() push_back() pop_front() pop_back() [] //overloaded, can be used with negative parameters But that data structure seems very clumsy, since so much pushing and popping is going on, I have to make a deep copy of the data structure before running an analysis on it. So, I don't know if I made my question very clear -- but the main points are: What kind of data structures should be considered when analyzing sequential data points to conform to a pattern that does NOT require random access? What kind of data structures should be considered when classifying extrema of a set of data points?

• After upgrading to 12.04 from 10.10 my mythbuntu standard MCEUSB remote no longer works

  - by keepitsimpleengineer

  I had no problems using my Windows Media Center Remote with 10.10 Mythbuntu, but after upgrading, it no longer affects Mythbuntu. I have verified and re-installed it in Mythbuntu Control Centre. I have used irw to verify the ir buttons actions are properly received by the HTPC. How do I go about fixing this? 3.2.0-26-generic (#41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012) Xorg version: 1.11.3 (16 July 2012 08:06:31PM) GCC: 4.6 (x86_64-linux-gnu) Current updates as of 2012?07?21 $cat /etc/lirc/hardware.con #Chosen Remote Control REMOTE="Windows Media Center Transceivers/Remotes (all)" REMOTE_MODULES="lirc_dev mceusb" REMOTE_DRIVER="" REMOTE_DEVICE="/dev/lirc0" REMOTE_SOCKET="" REMOTE_LIRCD_CONF="mceusb/lircd.conf.mceusb" REMOTE_LIRCD_ARGS="" #Chosen IR Transmitter TRANSMITTER="None" TRANSMITTER_MODULES="" TRANSMITTER_DRIVER="" TRANSMITTER_DEVICE="" TRANSMITTER_SOCKET="" TRANSMITTER_LIRCD_CONF="" TRANSMITTER_LIRCD_ARGS="" #Enable lircd START_LIRCD="true" #Don't start lircmd even if there seems to be a good config file #START_LIRCMD="false" #Try to load appropriate kernel modules LOAD_MODULES="true" # Default configuration files for your hardware if any LIRCMD_CONF="" #Forcing noninteractive reconfiguration #If lirc is to be reconfigured by an external application #that doesn't have a debconf frontend available, the noninteractive #frontend can be invoked and set to parse REMOTE and TRANSMITTER #It will then populate all other variables without any user input #If you would like to configure lirc via standard methods, be sure #to leave this set to "false" FORCE_NONINTERACTIVE_RECONFIGURATION="false" START_LIRCMD="" # lsusb | grep -i infrared Bus 003 Device 002: ID 0471:0815 Philips (or NXP) eHome Infrared Receiver

• USB to HDMI using just a cable

  - by Nirmal

  I got a cable which has a USB point on one side and an HDMI point on the other side. I was under an impression that I could watch movies from my computer if I connect my computer to the TV using this cable. But looks like I was wrong. Does anyone know if such cable need some driver to make it work? Thanks for any input. (My computer is a Dell All-in-one PC which cannot take an extra graphic card. That's why I am trying my luck with such a cable.)

• Cool Enhancements Everyone Can Enjoy

  - by Ruth

  With Release 17, we have a few visual and functional enhancements that make using CRM On Demand that much better for us all. I'll mention a few here, but to get the full outline of these upgrades, I recommend taking 10 minutes to view the Release 17 Usability Transfer of Information course. First and foremost, I find the ability to customize your theme (or skin) pretty cool, but I've said that before. Take a look at the Selecting Your Theme and the Themes - Create Your CRM Style blog articles for more information. My next favorite is the resizeable user interface (UI). CRM On Demand will dynamically fit the device and screen resolution you're using, which includes the resizing of fields, field editors and pop-ups. If you have a wide screen like me, you should appreciate that one very much. To make it easier to see that resized UI, the detail pages got a little face lift. New horizontal lines and other subtle changes make those pages easier to read. Also, those things you need to know, like error messages and inline help are highlighted with a little icon to show the message type. You may not think every change to the detail pages are particularly exciting, but I'm sure you'll enjoy the new Head Up Display, which saves you scrolling time by adding links to related information sections. I like that the head up display travels with me as I move up and down the page...it's like a little friend that takes me where I want to go as fast as possible. You may also really like the fact that the copy record feature is now available for all record types from both detail pages and lists. Your company administrator can choose which fields get copied, so you can maximize your efficiency when creating new records. Lists also got a face lift. Alternating colors in rows make it easier to see your data. Also, the Favorite Lists icon is now on the list itself, so you can save your most useful lists with one click. If you've ever tried to create a new list with 10 columns or more, you'll be happy to hear that the maximum number of columns in a list has increased from 9 to 20. This is great news, but doesn't mean you should include the kitchen sink in your list...excess columns can slow list performance. So choose your columns wisely. Again, these are just a few of my favorite things. Let us know what you think about the new usability features. What are your favorite things?
