  • The better way to ask for input?

    - by Skippy
    I am wondering which is the best way to go with java code. I need to create a class with simple prompts for input.. I have tried using both classes and cannot work out the particular benefits for each. Is this because I am still in the early stages of programming or are there situations that will occur as it becomes more complex?? import java.util.Scanner; public class myClass { Scanner stdin = new Scanner(System.in); public String getInput(String prompt) { System.out.print(prompt); return stdin.nextLine(); } ... or import java.io.*; public class myClass { public static void main(String[] args) throws IOException { BufferedReader stdin = new BufferedReader (new InputStreamReader (System.in)); System.out.print("Input something: "); String name = stdin.readLine(); I know these examples are showing different methods within these classes, but thought this might serve well for the discussion. I'm really not sure which site is the best to ask this on.

  • grep only returns help text

    - by Pete Mancini
    Well, I am perplexed. I am working with an Ubuntu server and I type in grep 'bash' *.sh BUT fgrep 'bash' *.sh works like a champ. which grep and which fgrep both point to their respective executables in /bin. I am perplexed as to what I am doing wrong. EXAMPLE output: $ grep -F 'grounding' repl.clj Usage: grep [OPTION]... PATTERN [FILE]... Search for PATTERN in each FILE or standard input. PATTERN is, by default, a basic regular expression (BRE). Example: grep -i 'hello world' menu.h main.c $ fgrep 'grounding' repl.clj (p/concepts-for-grounding-term imp1 "PERSON" "summary") See? grep is failing but fgrep is working fine. That is why I am perplexed.

  • Multiplayer approach for tablets on wi-fi (FPS/TPS)? Server authority, etc

    - by Fraggle
    Looking for some guidance or what has worked well for others in implementing a multiplayer FPS/TPS type game on tablets (probably just 2-6 players at a time). The main issue being that tablets/phones are typically "less" connected than say a console or pc might be. And therefore, my thought is that to have complete Server authority of everything is not going to work. But maybe I'm off base on that. So I guess I'm struggling with what (if anything) should happen on a central server and what should happen locally. Or is centralized approach even needed? Some approaches I might do: Player movement : my thought is to control this locally (player-owner) and update server with positon (which then sends out to other clients). Use client side prediction for opponent players so that connection loss will not show a plane for example stop in mid air. Server will send update and try to smoothly correct an opponent player position to server updated one.But don't update owners position on owners device from server. Powerups (health kit/ammo/coins/etc) : need to see them disappear immediately, so do it locally. Add the health locally, but perhaps allow for server correction. If server doesn't see player near that powerup, reject the powerup and adjust server health for player. Fire weapons: Have to see it happen right away, so fire locally, create local bullet and send on its way. Send rpc to server so that this player on other clients also fires. Hit detection: Get's trickier. Make bullet/projectile disappear locally, and perhaps perform local hit animations (shaking, whatever). non-authoritative approach= take the damage locally and send rpc to server or others to update health and inform of hit. Authoritative approach-Don't take the damage, or adjust health. Server will do that if it detects a hit. Anyway that's my current thought stream. Let me know what you think of the above or what has worked for you.

  • Emulate Historical Figures i.e. Einstein - Is this possible using linguistic logic for my http://www.ustimeline.com Education System

    - by Johnnylight
    After hearing about the success of IBM's Watson I started thinking perhaps emulating human language is now possible? My goal is to create Virtual Historical characters to represent the main characters in my Adventur-Cation The Great American Adventure program such as Einstein or Crazy Horse. The goal is to build an intelligent system capable of indexing the internet and storing the data using a schema using modern knowledge on linguistic theory (phonemes, morphemes, syntax) to build a system capable to returning a semantically sound response very similar to the response made by the same person if still alive today. The goal would be to use the same engine/system for all characters. Each characters would have their own digital representation and voice, and would organize data differently based on tags/keywords stored about the individual. Imagine a Max Headroom Einstein. Based on the success of Watson, I believe something like this may now be possible. Would be an interesting way to study history and would be a vehicle of entertainment as well. Can anyone confirm if this has already been attempted? Is anyone interested in exploring this using Cognitive Science, Psychology, Artificial Intelligence, Historical data captured on the internet, and Linguistic theory?

  • Games without a(n explicit) game loop

    - by Davy8
    Most game development happens with a main game loop. Are there any good articles/blog posts/discussions about games without a game loop? I imagine they'd mostly be web games, but I'd be interested in hearing otherwise. (As a side note, I think it's really interesting that the concept is almost exclusively used in gaming as far as I'm aware, perhaps that may be another question.) Edit: I realize there's probably a redraw loop somewhere. I guess what I really mean is a loop that is hidden to you. Frames are something you as the developer are not concerned with as you're working on a higher level of abstraction. E.g. someLootItem.moveTo(inventory, someAnimatationType) and that will move from the loot box to your inventory using the specified animation type without the game developer having to worry about the implementation details of that animation. Maybe that's how "real" games end up working, but from reading most tutorials they seem to imply a much more granular level of control is used, but that might just be an artifact of being a tutorial.

  • Which method of SQL Server 2005 or 2008 Replication is best for ease of field changes?

    - by Rick
    We need 15 minute warm updates from one SQL Server to another. Log Shipping looks good and appears easy to setup. We are also looking into Transactional Replication. The data only needs to copy one way. We have two main requirements: 1) The destination database needs to be a max 15 minute old copy of the source. It needs to re-try and get up-to-date if a network cable is unplugged for a while. 2) We would really like table (fields added or modified) changes in the source as easy as possible. Thanks in advance for all suggestions.

  • How can I get my email to go to Gmail and my hosted server?

    - by Joseph
    I've switched my main domain to point the MX to Google Apps, and my actual domain's server with the lowest MX priority. My idea is to have my primary emails on Google Apps, where the secondary are via Cpanel. Is this even possible? Currently MX records read: 0 Google 4 Google 4 Google 9 Google 9 Google 10 My server I have [email protected] which is added in G. Apps, and [email protected] which is only added in cpanel. Is there anyway to get this to work?

    I am looking for a software which I can host in popular and general shared web hosting services(online softwares like wordpress, meidawiki, drupal etc.) which can do the following- allow users to create account allow users or anons to add words to the dictionary (there will be English as base language and other languages) easier way to import all the words from English dictionary users should be able to write the that language equivalent of the English word Every word should have it's own address and page like www.namesomething.com/word/en/software will contain the word software and the other language word for it search should be faster and should find nearer results it's should be able to list related words like if the user is looking at "software" then other words from s like "softcopy" etc should appear alphabetically in that page Any one should be able to comment on the word which is not seen in the main page but other page similar to the talk page in the wiki any one should be able to contribute clean interface unlike wiki (media wiki and all other) just for words only I tried media wiki and other wiki software but it overloaded and unclean. I am looking for interface similar to oed.com but clean, minimal as we are not going to have such more information. Just words in English and it's other language equivalent. Here we are talking about a language which has not yet been in the Internet. It's should be collaborative.

  • Remote App - linked exe

    - by StaWho
    I'm experiencing below problem: I'm trying to run Microsoft NAV as remote app. There are two exe file involved: finsql.exe - main executable and finhlink.exe. Later one is used to directly run a 'window' within NAV (it takes certain link as parameter). This functionality is not present in finsql.exe. After configuring and running finhlink.exe as remote app I get an error "...finsql.exe can't be executed...". I believe it's because finhlink.exe is in fact invoking finsql.exe. Is there a way of allowing invocation of linked executable via remote app?

  • How to specify console (or primary display) for video adapter?

    - by Igor Zinov'yev
    I have an ASUS ENGT440/DI1GD5 video adapter which has three output ports: D-Sub (HD-15), DVI and HDMI. I am using both the D-Sub and DVI ports, but my main monitor is connected to the DVI output. Everything works fine except for which monitor is designated the console during boot. The video adapter seems to prefer the D-Sub output for the console. When both the VGA and DVI monitors are connected, then the VGA monitor always becomes the console which displays the motherboard logo, POST information and booting progress. When only the DVI monitor is connected, then it becomes the console as desired. How do I make the video adapter always use the DVI output (instead of the VGA port) for the console while booting?

  • ubuntu 12.04 installer does not recognize drive partitions

    - by endless forms
    I recently purchased a new HP Pavilion HPE desktop running Windows 7. I am trying to install a dual-boot system with 12.04. However, when I run the LiveCD I only get as far as the "Install" window where you can select the partitions for your drives. On the bottom where it says "device for boot loader installation" I have "/dev/sda" and cannot select any other devices. All the options to change the drives are greyed out, most likely because there are no drives in the window. I partitioned my largest drive using the tools within Windows, then booted into the CD, but nothing shows up. I then used Gparted to change the new space from unallocated to an /ext2, and still nothing shows up. The installer does not recognize anything, but when I go into an Ubuntu session and use the disk utility manager I can see the partitions I made. Anything I do has to be done outside of the installer. I have no files on this new computer, so this is the perfect time to install a parallel OS. I would like avoid completely reinstalling Windows, however. I've been over the forums many times, but all the answers I've found have not worked for me. I also tried flagging the new, empty partition as boot, but that screwed Windows up. Also, the WUBI installer hits the same point and quits. I know that the disk itself is fine because I just made another dual boot system on a Gateway PC. This makes me think something within this computer is preventing the installer from "seeing" the drives. Any help would be much appreciated! Edit in response: The main part of the partitioning window shows no partitions, everything is blank. There is no way to add partitions, and all the buttons are useless. I've tried defragging my drive multiple times, and I also used the same disk to dual-boot another PC with no problems, so it's not the disk, it's definitely the computer.

  • how did my laptop lose daylight savings time on power loss?

    - by EndangeringSpecies
    it was an old laptop that may or may not have dead CMOS battery (at least it had time reset to 0 when I dusted it off). So, it was plugged into power for awhile without the main battery and the clock was correct. Then there was a power outage. When I subsequently turned it on, surprise-surprise, it had one hour off correct time. So the clock apparently kept running during the outage, but daylight savings time info vanished (from disk? where is it stored?) How come?

  • Where does gcc keep its built-in include directory paths

    - by Charles
    GCC has built in include directories for certain standard headers. I just need to know where this list is. My newly compiled gcc will not compile my little test C++ program because it cannot find standard headers. I think it fails because of some config options I used to make my file system more organized. I set the bindir and libdir, which I think might have screwed up the built-in include paths for some reason. Program (dummy.c): #include <iostream> void main(){} Command: g++ dummy.c Error: dummy.c:1:20: fatal error: iostream: No such file or directory

  • Do I need a Gigabit router with a 24MB/s down and 7MB/s upload speed cable modem?

    - by djangofan
    Do I need a Gigabit port capable wireless router with a 24MB/s down and 7MB/s upload speed cable modem? Does anyone know how to calculate this? FYI, I wont be using the wireless connection from my main computer system. My computer will connect via a hard wire into the router (of the wireless variety), which in turn is connected to the cable modem. My research suggests that the 100 MB/s port can easily handle it. Is that true?

  • Make iMovie text overlay remain on screen after in-transition

    - by Kit
    My idea of a text overlay has the following timeline: In-transition Static display Out-transition For this project, I am particularly fond of iMovie's Organic Main text overlay. I want it to display for an extended period. The problem is, when I set its display time for 3:20 (minutes:seconds), it performs its transition over the whole period. The text would won't be fully seen until the next 3 minutes. This is what I want: In-transition for 1 second Static display for 3:18 minutes Out-transition for 1 second Is that possible with iMovie?

  • WDS (Wireless Distribution System) not work [migrated]

    - by xdevel2000
    I've a dlink di-524 as main router (192.168.0.1) connected to Internet and a second router (192.168.0.2), a tplink wr841n, with WDS enabled and correctly configured to "join" with dlink. After I connect via wireless a laptop (192.168.0.100) to tplink and both work good but with the laptop I can't go to Internet. It seems as WDS not work. With the laptop I can only ping the tplink but other ping (the dlink or other LAN computer not responding). What's the problem? Perhaps also the dlink must have the WDS option? Thanks.

  • My NTFS Partition keeps becoming "unusable" on Ubuntu, Any Ideas?

    - by gopherman
    I just purchased a new 2TB Drive External Seagate, My main system uses both Windows and Ubuntu So I am pretty much stuck with keeping my drive as NTFS. I have done this without any problems before but since I got this new drive I have been having issues. When I first load up Ubuntu the drive mounts and runs fine, after an unspecified amount of time i start getting Input/Output errors when accessing the drive. When I goto the Disk Utility I get a message stating the drive is "Unknown or Unused", If I disconnect and reconnect the drive or reboot everything is fine again. There's no errors coming up with S.M.A.R.T and it seems to work fine while under windows. Any thoughts?

  • Multiple domains for different products?

    - by alexandertr
    I have a website with software applications. Is it good for SEO to choose one keyword rich domain name for each of our software products or should we stick to a single domain? From a user's perspective I think it would be easier to remember a domain that is keyword rich as the user will instantly know what this product is for. But I have read articles that the latest trend in SEO is to stick to one domain for all of your products and invest on this single domain website. Is that true? What do you advise? Should I register a separate domain for each of our products or should I use only one single domain? Should I do a 301 redirect with a .htaccess to a single domain? And what about the sitemaps? Should I register all sites in Google Webmaster Tools and post a separate sitemap for each one of them? should my main site sitemap include all pages or should separate domains have their own sitemaps?

  • How to create repeatable table with unique ID's using jQuery

    - by milbert
    I need to create a table structure that can be "copied" and populated with a new set of data. However, each table must have unique IDs for functions that must access them later. For example: <table class="main"> <thead><tr><th class="header"></th></tr></thead> <tbody> <tr class="row"><td class="col0"></td><td class="col1"></td></tr> </tbody> </table> My current thought is to use jQuery to load the table from a seperate html file into a variable. Using this saved table I could then create a function that copies it, traverses the table to add an ID to each section where information will need to be appended from a seperate data source, and return this new table. I am new to jQuery and feel like I may be missing an easier/better way to accomplish this. Any help on this subject would be appreciated.

  • Google is displaying "Translate this page" based on a previously registered domain inbound links

    - by crnm
    I recently started a new project with a newly registered generic tld domain. As soon as Google started indexing the page, it displayed a "translate this page" in SERP's, which tries to translate the page to the language of a small Eastern European country from the language that the site actually uses. I tried everything to prevent this: language meta headers and attributes, localisation through Google Webmaster Tools...all to no avail - nothing helped. After a couple of weeks I spotted dozens of inbound links popping up in Google Webmaster Tools all coming from that small Eastern European country, from sub-pages that are not active anymore (either sending out 404's or 301's to the main page), and also had been written in that other language. So the domain had been registered before and as it looks, it did got a lot of possibly spam links in that language. I can't even ask the sites where those links should have been to remove them as they are not active anymore physically, just in Google Webmaster Tools and/or internal data masses... Now I'm at a loss about what to do? As my site is pretty new, it does not have many links pointing towards it in my targeted language. So those are probably not enough to convince Google of attaching the right language to it as Google ignores all other signals about the page language. I'm also unsure if I should use the "disavow" tool, or a reconsideration request...or what else to do about this miserable state. I never used these tools before so I don't have any experience with them. Somehow I have to convince Google about the right language of the page and also to not count/apply/whatever all those historical links from the previous owner. (The domain had been deleted without any traces in Google before I registered it) Has anyone here ever dealt with a similar "Translate this page" problem? (I've also looked at this thread: How can I prevent Google mistakenly offering to translate a page? but didn't find a solution there)

  • How does a private intra network connect to the internet?

    - by user24454
    Yesterday I visited the offices of RailTel - a public company in India that provides communication backbone to the Indian Railways, they had a very sophisticated setup of Optical Fiber cables for data transmission. They said that this is a private network for internal use only. Then when I was in the Exchange Office - the main communication office, a place where they actually use those communication channels. They said that we could connect to the Intranet and as well as the Internet! My question is, that how is this possible? How can privately laid optical fibers connect globally? On google, I picked up the term internet exhange? But this has got me confused further, why would a private network want to go to this exchange? Please explain me in very simple terms, how does this all work? If this is just a connection of wires, then why charge so much for little bandwidth? Thanks.

  • 301 redirect: Is this good or bad for 2 domains?

    - by Tim
    Since i couldn't find any appropriate answer to my specific question, I wanted to ask you. I've read alot of things about the 301-redirect for moving pages and so on. A customer of mine has booked a new domain last year for better search results (he included his main keyword into the domain. Before he had only a domain with his business name, which had nothing to say about what he does). I told him, that he should do a 301-redirect so he doesn't loose his position in Google and to redirect all new customers coming from the old domain to the new domain. After about one year where his site hat a good amount of traffic the search results of Google for his keywords are getting more worse. Since he didn't maintain his website (no new content, bad content on all pages and so on) I assumed this would be the problem. He gave his website to another company which also makes websites. They told him, that this 301-redirection is very bad for his website. They removed it, and also updated his content and the template so now he has the same meta keywords on every page (instead of the specific ones I put there before). He also removed the canonical-tag which I placed there to ensure no duplicate content. What I am now afraid of is, that without this redirect Google now will find duplicate content and therefore kick him out of the index, which would be a nightmare, since most of his customers come over his website. I need verification of the fact, that the 301 isn't bad but in fact the correct way of working with 2 domains. If possible with good sources I can point out to him since he don't wants to hear anything about this. If someone also has a few words about the keywords and the canonical-tag I would really appreciate it! Thank you very much!

  • EXT4 external hard drive for use with multiple systems

    - by EXTdumb
    I recently bought a external hard drive to store some data on. I use Linux but I am not a power user. If I format the drive to EXT4, is it possible for the permissions to ever screw up and I lost access to my data? I will be plugging the drive into several different linux based computers at work and I frequently hop distros on my main home machine. I need to make sure I don't lose any data because I overlooked something. I am not familiar with EXT 3 or 4. So far I have done this : Formatted drive to EXT4 ran gksudo thunar and changed the permissions to my user account and all settings to read/write Wrote all the files I need to the drive I really appreciate any help.
