  • [NEWVERSION]algorithm || method to write prog[UNSOLVED] [closed]

    - by fatai
    I am one of the computer science student. Everyone solve problem with a different or same method, ( but actually I dont know whether they use method or I dont know whether there are such common method to approach problem.) if there are common method, What is it ? If there are different method, which method are you using ? All teacher give us problem which in simple form sometimes, but they donot introduce any approach or method(s) so that we cannot make a decision to choose the method then apply that one to problem , afterward find solution then write code.No help from teacher , push us to find method to solve homework. Ex: my friend is using no method , he says "I start to construct algorithm while I try to write prog." I have found one method when I failed the course, More accurately, my method: When I counter problem in language , I will get more paper and then ; first, input/ output step ; my prog will take this / these there argument(s) and return namely X , ex : in c, input length is not known and at same type , so I must use pointer desired output is in form of package , so use structure second, execution part ; in that step , I am writing all step which are goes to final output ex : in python ; 1.) [ + , [- , 4 , [ * , 1 , 2 ]], 5] 2.) [ + , [- , 4 , 2 ],5 ] 3.) [ + , 2 , 5] 4.) 7 ==> return 7 third, I will write test code ex : in c++ input : append 3 4 5 6 vector_x remove 0 1 desired output vector_x holds : 5 6 now, my other question is ; What is/are other method(s) which have/has been; used to construct class :::: for c++ , python, java used to communicate classes / computers used for solving embedded system problem ::::: for c by other user? Some programmer uses generalized method without considering prog-language(java , perl .. ), what is this method ? Why I wonder , because I learn if you dont costruct algorithm on paper, you may achieve your goal. Like no money no lunch , I can say no algorithm no prog therefore , feel free when you write your own method , a way which is introduced by someone else but you are using and you find it is so efficient

  • Help imorting video from old Sony Digital Tape handycam

    - by thatryan
    Friend gave me their OLD handycam and a bunch of tapes asking me to put them on a DVD. The model is Sony DCR-TVR103 and it records onto Hi8 Digital tapes. It has a firewire port also. I am trying to use import function in iMovie on OS X 10.6. Every import though the video is super fast, like playing in fast forward. Ever seen anything like this? How can I import this video? Thank you.

  • Intel cpu hyperthreading on or off for ibm db2?

    - by rtorti19
    Has anyone ever done any database performance comparisons with hyper-threading enabled vs disabled? We are running ibm db2 and I'm curious if anyone has an recommendations for enabling hyper-threading or not. With hyper-threading enabled it makes it quite difficult to do capacity planning for cpu usage. For example. "With 8 physical cores represented as 16 "threads" on the OS and a cpu-bound workload, does that mean when your cpu usage hit's 50% you are actually running at 100%." What real benefits do I gain with leaving hyper-threading enabled on an intel server running DB2? Does hyper-threading help if you're workload is truly disk IO bound? If so, up to what percentage? These are the types of questions I'm trying to answer. Any thoughts?

  • Any beat detection software for Linux?

    - by o_O Tync
    Amarok 2 can search through music collection using ID3v2 tag's 'bpm' field. That would be very nice to retag the entire music collection so I can find the 'mood' of the track I like. However I've not found any beat-detection software that could have helped me. Have you ever used one? CLI, preferably. Also I'm interested if there's anything alike for tagging FLACs with the same 'bpm' field. Thanks! :) P.S. I'm aware there's a nice moodbar feature, however it's useless for searching.

  • RAID 10: SPAN 2 vs SPAN 4

    - by LaDante Riley
    I am currently configuring RAID 10 (first time doing RAID ever) for a server at work. In the Configuration Utility. I am given the option of either span 2 or span 4. Having never done this before, I was curious if someone could tell me the pros and cons of for each span? Thanks The server is a Poweredge r620 with a PERC H710 mini (Security Capable) RAID controller. I have 8 600GB hard drives. I am creating this server as a network storage drive. I have SQL server historian database whose 1TB storage filled up and after 5 years of logging data.

  • Game Server Colocation

    - by Linuz
    Hello, I am new to colocation. I am looking for a good place to host my server that would have around 5-10 Source Servers (Team Fortress 2). I am looking at maybe around 90 players at a time for now, players coming from all over the United States Could I get more info on what I am suppose to look for exactly? Would it be correct for me to get a 100Mb/s line and does 100Mb/s line in the following example actually be 100Mb/s upload bandwidth? Example: package 4 of FDC's services: http://www.fdcservers.net/server_colocation.php also I want to get something unmettered. I do not want to have to ever worry about going over some bandwidth limit or any DDOS attacks killing me. And if anyone has any other recommendations as to what network configurations I should get or any other good colocation providers that are cheap in price, I would REALLY appreciate the help. Thanks

  • CA ArcServe r11.1 - have to switch Tape Drive Offline then Online to finish backup

    - by Richard
    Ill keep it brief, I have an HP Ultrium 1 in a server currently running CA ArcServe r11.1. I have 5 daily backup tapes, each of which are new. 3 of the 5 work fine without intervention but 2 of them stop at varying points through the backup asking for a new tape, even though that tape is not full. The way I have found around this is to switch the tape drive offline for 10 minutes then switch it back online, whilst the backup is still running. Has anyone ever seen this before? If so, any ideas how to permanently fix this. If all else fails just some pointers in the right direction. Thanks

  • Export and import a PostgreSQL database with a different name?

    - by J. Pablo Fernández
    Is there a way to export a PostgreSQL database and later import it with another name? I'm using PostgreSQL with Rails and I often export the data from production, where the database is called blah_production and import it on development or staging with names blah_development and blah_staging. On MySQL this is trivial as the export doesn't have the database anywhere (except a comment maybe), but on PostgreSQL it seems to be impossible. Is it impossible? I've seen out there some people using sed scripts to modify the dump. I'd like to avoid that solution but if there are no alternative I'll take it. Has anybody wrote a script to alter the dump's database name ensure no data is ever altered?

  • Ruby: Continue a loop after catching an exception

    - by Santa
    Basically, I want to do something like this (in Python, or similar imperative languages): for i in xrange(1, 5): try: do_something_that_might_raise_exceptions(i) except: continue # continue the loop at i = i + 1 How do I do this in Ruby? I know there are the redo and retry keywords, but they seem to re-execute the "try" block, instead of continuing the loop: for i in 1..5 begin do_something_that_might_raise_exceptions(i) rescue retry # do_something_* again, with same i end end

  • Microsoft Excel Error

    - by Chris
    I am working with a user that has Office 2007 installed. When they open excel with a blank workbook and then they try to close excel without having done anything, it gets hung for about a minute or two and then gives the warning message: "Microsoft Office Excel is waiting on another application to complete an OLE action." Has anyone ever seen this happen before? If so can you please help me figure out how to resolve this. It doesn't matter what excel file they open or if it is a blank/new workbook. Please Help.

  • What could cause my browserS to keep crashing?

    - by Guy Thomas
    The situation: Windows 7 ultimate on standard box 4 GB RAM. The problem: IE 8 kept on crashing. Tried upgrading to IE 9 - no better. Then I thought I will have to kick IE into touch and go with Firefox. Same problem Firefox crashes. Gave Chrome a chance - same problem the browser just says sorry, and closes / restarts. Other problems, this is not the best machine I have ever had, Word sometime closes unexpectedly, and I have trouble with Microsoft Updates failing first time.

  • Optimizing tasks to reduce CPU in a trading application

    - by Joel
    Hello, I have designed a trading application that handles customers stocks investment portfolio. I am using two datastore kinds: Stocks - Contains unique stock name and its daily percent change. UserTransactions - Contains information regarding a specific purchase of a stock made by a user : the value of the purchase along with a reference to Stock for the current purchase. db.Model python modules: class Stocks (db.Model): stockname = db.StringProperty(multiline=True) dailyPercentChange=db.FloatProperty(default=1.0) class UserTransactions (db.Model): buyer = db.UserProperty() value=db.FloatProperty() stockref = db.ReferenceProperty(Stocks) Once an hour I need to update the database: update the daily percent change in Stocks and then update the value of all entities in UserTransactions that refer to that stock. The following python module iterates over all the stocks, update the dailyPercentChange property, and invoke a task to go over all UserTransactions entities which refer to the stock and update their value: Stocks.py # Iterate over all stocks in datastore for stock in Stocks.all(): # update daily percent change in datastore db.run_in_transaction(updateStockTxn, stock.key()) # create a task to update all user transactions entities referring to this stock taskqueue.add(url='/task', params={'stock_key': str(stock.key(), 'value' : self.request.get ('some_val_for_stock') }) def updateStockTxn(stock_key): #fetch the stock again - necessary to avoid concurrency updates stock = db.get(stock_key) stock.dailyPercentChange= data.get('some_val_for_stock') # I get this value from outside ... some more calculations here ... stock.put() Task.py (/task) # Amount of transaction per task amountPerCall=10 stock=db.get(self.request.get("stock_key")) # Get all user transactions which point to current stock user_transaction_query=stock.usertransactions_set cursor=self.request.get("cursor") if cursor: user_transaction_query.with_cursor(cursor) # Spawn another task if more than 10 transactions are in datastore transactions = user_transaction_query.fetch(amountPerCall) if len(transactions)==amountPerCall: taskqueue.add(url='/task', params={'stock_key': str(stock.key(), 'value' : self.request.get ('some_val_for_stock'), 'cursor': user_transaction_query.cursor() }) # Iterate over all transaction pointing to stock and update their value for transaction in transactions: db.run_in_transaction(updateUserTransactionTxn, transaction.key()) def updateUserTransactionTxn(transaction_key): #fetch the transaction again - necessary to avoid concurrency updates transaction = db.get(transaction_key) transaction.value= transaction.value* self.request.get ('some_val_for_stock') db.put(transaction) The problem: Currently the system works great, but the problem is that it is not scaling well… I have around 100 Stocks with 300 User Transactions, and I run the update every hour. In the dashboard, I see that the task.py takes around 65% of the CPU (Stock.py takes around 20%-30%) and I am using almost all of the 6.5 free CPU hours given to me by app engine. I have no problem to enable billing and pay for additional CPU, but the problem is the scaling of the system… Using 6.5 CPU hours for 100 stocks is very poor. I was wondering, given the requirements of the system as mentioned above, if there is a better and more efficient implementation (or just a small change that can help with the current implemntation) than the one presented here. Thanks!! Joel

  • Get sudoers information for all users on a server

    - by Jon Kruger
    I want to collect information on what sudoers actions a user can perform on a server. From what I've read, you can do this with the command sudo -l -U username. However, one server that I have has a slightly older version of sudo (1.6.7p5) and the -U option doesn't seem to exist (I don't own the server so I can't just upgrade to a newer version of sudo). Has anyone ever had to collect sudoers information for all users on a server? How would you recommend doing it?

  • shuffling array javascript

    - by Dennis Callanan
    <!doctype html> <html lang="en"> <head> <meta charset="utf=8" /> <title>Blackjack</title> <link rel="stylesheet" href="blackjack.css" /> <script type="text/javascript"> var H2 = 2; var S2 = 2; var D2 = 2; var C2 = 2; var H3 = 3; var S3 = 3; var D3 = 3; var C3 = 3; var deck = new Array(H2, S2, D2, C2, H3, S3, D3, C3); var new_deck = new Array(); var r; document.write("deck = ") for (r =0; r<deck.length; r++){ document.write(deck[r]); } document.write("</br>") document.write("new deck = ") for (r=0; r<new_deck.length; r++){ document.write(new_deck[r]); } document.write("</br>") for (r=0;r<deck.length;r++){ var randomindex = Math.floor(Math.random()*deck.length); new_deck.push(randomindex) deck.pop(randomindex) } document.write("deck = ") for (r =0; r<deck.length; r++){ document.write(deck[r]); } document.write("</br>") document.write("new deck = ") for (r=0; r<new_deck.length; r++){ document.write(new_deck[r]); } document.write("</br>") </script> </head> <body> </body> </html> Obviously this isn't the full Blackjack game here. It's just a test to see if shuffling the array works by printing the contents of both decks (arrays) before and after the shuffle. I'm only using 8 cards at the moment, 4 2's and 4 3's. What I am getting from this is: deck = 22223333 new deck = deck = 2222 new deck = 7502 What I'm hoping to get is: deck = 22223333 new deck = deck = new deck = 23232323 (or any of the 8 numbers, generated randomly) So it should be shuffling those 8 cards, what am I doing wrong? I'm only new to javascript but I've used some python before. I've done something similar in python and worked perfectly, but I'm not sure what's wrong here. Thanks for any answers in advance!!

(let me know if Im to vague)

  • Restoring using SyncBack without profiles

    - by Thomas Matthews
    I backed up my internal hard drive (C:) using SyncBack onto an external (USB) hard drive with maximum compression. I then performed a clean install of Windows Vista onto the computer. I forgot to copy the SyncBack logs before the clean install. And now when ever I try to restore a directory, the RAR/ZIP files are copied to the system hard drive instead of extracting their contents to the hard drive. Also, SyncBack is not traversing the folders during the Restore process. How can I tell SyncBack to expand the compressed files? I am running the freeware version of SyncBack. I have to create new log files (unless SyncBack put them somewhere on the external drive). My alternative is to write a program that traverses the folders on the external drive and extracts files from the RAR/ZIP files. I am using Windows Vista, Service Pack 2, and the data size prior to backup was about 200 GB. (The backup process took over 72 hours due to "hiccups").

  • Munin Mongodb Plugin Not Showing. . . ?

    - by alfredo
    I have installed munin and munin-node on my monitoring server and installed munin-node on my mongodb server, I have set them both up and all is working great. But, the mongodb plugins aren't showing on my monitoring server. I see the node listed and "Disk, Network, Processes, System", but not the mongo stuff. If I execute one of the plugins directly on the mongo server "python /usr/share/munin/plugins/mongo_btree" it returns output, but nothing shows on the monitoring server.

  • chrome-like status bar in qt

    - by hasen j
    I'm not big on creating GUI's, and generally my philosophy is: I don't create them, or I make them as simple as possible (and convince myself that it's better for usability :) For my current project, I'm using Qt from Python (PyQt), and I want to start adding some GUI elements without cluttering the interface. My idea is to create these elements as sort of floating-shaped-widgets that only appear when necessary; pretty much like the status bar (and find bar) in chrome. Is there any standard api that enables creating this kind of interface?

  • Any way to disable Ctrl+L keyboard shortcut for clearing scrollback in Pidgin?

    - by mikez302
    I am using Pidgin 2.7.1 on Windows XP and I noticed that if I am in a conversation window and I press Ctrl+L, it clears my conversation history and there is no easy way of getting it back (as far as I know). I think this keyboard shortcut is very annoying. I never do this on purpose. It usually happens if I think I am in Firefox and I try to focus the address bar by pressing Ctrl+L, but instead end up clearing my pidgin scrollback. I have no use for such a quick and easy way of triggering a feature that I will rarely, if ever have any reason to use. Is there any way of disabling the keyboard shortcut?

  • Auto Log-Off Windows users - Windows 2003 domain

    - by thehatter
    I am trying to make windows clients automatically log off after some time, I have been trying to use the winexit.scr which I have seen working else where in a similar environment. After working though these instructions (I did read the comments and notice the original ADM provided is buggy) I've had no joy what so ever! Winexit.scr refuses to read any settings in the registry, even while using a test account I can access the required reg key(s); edit, add, and remove values. Essentially winexit.scr always uses it's default values: 30 second timeout, no forced log-out. What I really want is a 30 minute timeout with a forced log-out, closing all the users apps etc. I've tried removing and re-adding the ADM template, creating the GPO from scratch several times, giving various registry permissions - including full control to "Everybody" just for fun! Oh, clients are all win XP SP3, DC is win 2003 R2 SP2. So, can anybody suggest something? Cheers!

  • After repairing permissions, Mac OS X won't boot

    - by Power-coder
    This morning I ran the Repair Permissions command from inside the Disk Utility. Ever since then my MacBook wont move past the splash screen when booting. I've revolted in verbose mode and I see that it is trying to repair the disk but then terminates with 'Unable to repair the volume'. Since then I have tried running the Disk Repair from the Snow Leopard install DVD and it quits with the same error. Is there a way I can repair this thing without reformatting and installing over again? How does something so simple as a permissions repair make the system unbootable like this?
