  • What is the most complicated data structure you have used in a practical situation?

    - by Fanatic23
    The germ for this question came up from a discussion I was having with couple of fellow developers from the industry. Turns out that in a lot of places project managers are wary about complex data structures, and generally insist on whatever exists out-of-the-box from standard library/packages. The general idea seems to be like use a combination of whats already available unless performance is seriously impeded. This helps keeping the code base simple, which to the non-diplomatic would mean "we have high attrition, and newer ones we hire may not be that good". So no bloom filter or skip-lists or splay trees for you CS junkies. So here's the question (again): Whats the most complicated data structure you did or used in office? Helps get a sense of how good/sophisticated real world software are.

  • [Dear Recruiter] I'm an engineer trapped in a kittens body.

    - by refuctored
    Aditya -- I am very interested in pursuing the opportunity you've presented to me.  Let me assure you, there are very few individuals in Indianapolis with the skill set which I have so passionately trained to acquire.   Accompanying my skill set I do have a few quirks that you'll need to be okay with prior to placing me at a company. Bluntly, I feel like I'm a software engineer trapped in a cute little kitten's body.  I find that I am most comfortable going to work with a few stripes and whiskers painted on my face.  Coworkers will need to be okay with me grooming myself and making kitten noises whilst I do so.  I do occasionally let out a purr now and then, but not loud enough to disrupt anyone.  I always throw my arm-hair-balls in the appropriate trash receptacle. Will your company provide a scratching post or will I need to bring my own?  I can bring my own litter box. Meow-muh,George

  • iCloud : Apple pourrait accéder aux données de ses utilisateurs mais son service est loin d'être le seul dans ce cas, le Cloud en question ?

    iCloud : Apple aurait accès aux données hébergées de ses utilisateurs Mais son service est loin d'être le seul, le Cloud en question ? Le débat sur le Cloud et les espaces de stockages hébergés risque d'être relancé. Depuis hier, un site américain renommé affirme en effet qu'Apple aurait accès aux données que ses utilisateurs décident de stocker ou de synchroniser (musique, contacts, photos, favoris, etc.) via iCloud. Soulignons tout de suite qu'Apple est loin d'être le seul dans cette situation puisque Ars Technica indique que des services comme Box.net ou Dropbox (entre autres) seraient également concernés. « Vos informations ne sont pas à l'abris des yeux indiscrets ...

  • Inputting cheat codes - hidden keyboard input

    - by Fibericon
    Okay, here's what I want to do - when the player is at the main menu, I want them to be able to type in cheat codes. That's the only place I want it to work. I don't want to give them a text box to type into. Rather, I want them to simply type in a word (let's say "cheat", just for simplicity sake) that activates the cheat code. I only need to capture keyboard input when the window is in focus. What can I do to accomplish this?

  • Windows 8 and "Formerly known as Metro" apps, an experience with PDF app

    - by Kevin Shyr
    I'm slowing and surely getting used to Windows 8.  It is no doubt a slow process since I still run daily on an XP machine, a Vista machine, and 3 windows 7 box. A new quirk I found regarding Windows 8.  I never thought it was important to learn how to close a "formerly known as Metro" app (what do we call those these days?).  Then I attached a portable drive to my laptop and opened up a PDF file, and I couldn't safely remove the hard drive afterwards because I did not know how to close the PDF reader app. I have since learned that if you want to close an app, you can try Alt + F4 mouse over the top left corner and swipe down, right-click to close you app Windows Key + TAB, right-click to close the app All these make me wonder, how do you do this in a phone or tablet?

  • How is Logitech C510 HD Webcam

    - by Ashfame
    I am going to buy Logitech C510 HD webcam and I just checked on other questions here on AskUbuntu that it works out of the box with cheese. Jorge's response also confirm this and I feel confident buying it now. My question is can it be limited in any functionality that I would like to do with it? I would like it to be used with everything - Skype, Gtalk video chat, Facebook, Youtube etc. Also this may sound lame but I need to know whether I could record or do a video call in lesser resolution video (its a 720p one)? Edit: Ported part of this question to another question to make it more specific.

  • Run programs that require a window manager, on the CLI

    - by Twitchy
    Is there any way I can run a game server (MW3) under wine without requiring a window manager present? Currently to run windows only game servers on my Ubuntu box, I have to start them using RDP access as this creates a X session which the program (which has its own GUI). This is a pain as it cannot be automated (or can it?) on start up. What I would rather is some sort of X session emulator that pulls the console output of the program into the CLI so that I can automate server start ups. Is there any program or method that can do this?

  • Reputable web host in mainland China? [closed]

    - by darren
    Possible Duplicate: How to find web hosting that meets my requirements? We currently have a rather poorly set up Windows 2003 box with little to no support based in Shanghai; with no control panel/mail server. I am told for legal/business reasons the host must be based in the same location as the company for the website; but this could well be misinformation. Are there any well-known, quality hosts in China that offer reliable English-speaking support? We did consider GoDaddy on the west coast of America, but were informed of the risk of the site being shut down without any notice. We don't have any technically-minded contacts out there to advise, and hoping that someone will have some more experience in this department. Thank you.

  • Box2Dweb very slow on node.js

    - by Peteris
    I'm using Box2Dweb on node.js. I have a rotated box object that I apply an impulse to move around. The timestep is set at 50ms, however, it bumps up to 100ms and even 200ms as soon as I add any more edges or boxes. Here are the edges I would like to use as bounds around the playing area: // Computing the corners var upLeft = new b2Vec2(0, 0), lowLeft = new b2Vec2(0, height), lowRight = new b2Vec2(width, height), upRight = new b2Vec2(width, 0) // Edges bounding the visible game area var edgeFixDef = new b2FixtureDef edgeFixDef.friction = 0.5 edgeFixDef.restitution = 0.2 edgeFixDef.shape = new b2PolygonShape var edgeBodyDef = new b2BodyDef; edgeBodyDef.type = b2Body.b2_staticBody edgeFixDef.shape.SetAsEdge(upLeft, lowLeft) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(lowLeft, lowRight) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(lowRight, upRight) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(upRight, upLeft) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) Can box2d really become this slow for even two bodies or is there some pitfall? It would be very surprising given all the demos which successfully use tens of objects.

  • Which drivers do I need for Ethernet and CAN bus on Intel Tolapai?

    - by Hanno Fietz
    I've installed 10.04 Server on an embedded machine (NISE 110 by Nexcom) and the builtin Ethernet and CAN-bus controllers don't work out of the box. The controller seems to be an Intel EP80579 chipset for both, according to lspci. I tried Intel's product website, where they seem to have FreeBSD drivers only. There's also drivers for RedHat, but I'm struggling with the manual build required to get them to work. Googling so far didn't get me anywhere. Which drivers do I need, and where do I get them?

  • How do I make the top panel transparent in Unity?

    - by neildeadman
    I'm using a fresh install of Ubuntu 11.10 using Unity. I'm a newbie to Ubuntu and whilst researching various how-to's, I have seen screenshots where Ubuntu has the bar at the top of the screen shown transparent. I really like this, but I can't get it to do it on my box. I have tried CCSM (2 different methods), Ambience theme editing (a copy) but it always shows as black. I log out after each change and then log back in. Should I be restarting? I'm running: Asus P5Q Pro Intel Core 2 Quad Q6600 @ 2.40GHz x4 GeForce 9600GT 32-bit OS 4x 1GB DDR2 RAM Modules (although BIOS only shows I'm using ~3GB)

  • How many BasicEffects do you have in a Game? What is the best way to render multiple objects/shapes at once?

    - by Deukalion
    I'm trying to understand 3D rendering and it seems that everytime you render a new object (A 3D Cube or something) you need to have a new BasicEffect for each Box you render unless you want the exact same texture? ...so if I have over a hundred boxes with each different textures, I need at least as many BasicEffects? Will that not be "too much" for the CPU/GPU in the end or result in lagging? Is there any good way to render multiple objects (cubes or other shapes) at the same time? I've tried changing the BasicEffect.Texture with each cube drawn, but it resulting in changing the first Cube's texture too. Any suggestions would be really appreciated, I'm really new to 3D in XNA so I'm trying to wrap my head around the best methods for example render a Map with objects (of shapes).

  • Unable to boot 12.04 server: no LVM activated and impossible to mount /

    - by baronKarza
    I'm stuck in the Busy Box shell after upgrading from Ubuntu server 11.10 to Ubuntu server 12.04 64 bit. During the booting phase the system hangs while mounting root filesystem. My system is so configured: /dev/sda1 -- /boot /dev/mapper/vg-lv_root /dev/mapper/vg-lv_var /dev/mapper/vg-lv_tmp When the boot process fails and I'm forwarded to the busybox shell, if I type vgchange -ay I can mount my volumes and all it's OK. But it does not enable LVM automatically so that it is impossible to mount root, var, and tmp. I tried to start with a Knoppix, chroot, reinstall (aptitude) both kernel and lvm2 as suggested by this tread "Fixing unbootable installation on LVM root from Desktop LiveCD": nothing changed. I can't figure out what is the problem. Any suggestion is welcome. Thanks in advance.

  • jquery slidetoggle expands and collapses straight away [migrated]

    - by Floran
    Please see here: http://www.wunderwedding.com/weddingvenues/search On the left side there's a filter 'show more cities...' When it's clicked I want to show more cities. But right now when it's clicked the box expands and IMMEDIATELY collapses again. I dont know what Im doing wrong. This is the code for show/hide: $("#toggle_cities").click(function () { if ($("#facets_city").is(":visible")) { $("#toggle_cities").text('toon meer steden...'); } else { $("#toggle_cities").text('toon minder steden...'); } $("#facets_city").slideToggle("slow"); });

  • What is a light-weight "slideshow" script that could integrate w/ CMS?

    - by aslum
    I'm looking to reduce the footprint of my Strict html 4.01 front page. One possible way is to combine much of the "upcoming events" into a single small box, and have them automagically switch which one is displayed every few seconds. I'm sure there are a bunch of this kind of thing written already, and surely an open source one exists, but I haven't had much luck find one. I'd prefer javascript to jQuery as installing jQuery might not be an option, but if the best-fit script requires jQuery I'd certainly be willing to investigate that route. If it can display content from Wordpress that would be ideal.

  • How do I suppress the "New release '12.10' available" message?

    - by cjm
    When I ssh into my Mythbuntu box, I get this message: Welcome to Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-32-generic x86_64) * Documentation: https://help.ubuntu.com/ New release '12.10' available. Run 'do-release-upgrade' to upgrade to it. Last login: <redacted> $ But I don't intend to upgrade to 12.10, because Mythbuntu recommends using LTS releases only. How do I suppress the "New release '12.10' available" message? I don't want to be notified until the next LTS release is available. I've already gone to Update Manager Settings Updates and selected "Notify me of a new Ubuntu version: For long-term support versions", but that didn't get rid of this message.

  • Covering Yourself For Copyrighted Materials [on hold]

    - by user3177012
    I was thinking about developing a small community website where people of a certain profession can register and post their own blogs (Which includes an optional photo). I then got to thinking about how people might use this and the fact that if they are given the option to add a photo, they might be likely to use one that they simply find on Google, another social network or even an existing online blog/magazine article. So how do I cover myself from getting a fine slapped on me and to make it purely the fault of the individual uploader? I plan on having an option where the user can credit a photo by typing in the original photographers name & web link (optional) and to make them tick a check box stating that the post is their own content and that they have permission to use any images but is that enough to cover myself? How do other sites do it?

  • Looking for bug tracking software

    - by Shelton
    I'm looking for a bug/issue tracking system that can: Integrate with lots of other services. Basecamp, Beanstalk, etc. Integrate popular CMSs, such as WordPress, so the client can enter a ticket from the system that is familiar to them and not have one more login to worry about. Generate reports for my own purposes. Bonus if there's an iPhone app. Doesn't require additional development on my end (I have plenty of money and no time). I've already looked into Lighthouse and ZenDesk -- both are solid offerings -- but don't see what I need out of the box. I'd have to build CMS plug-ins. And I've looked through WP plug-ins for bug tracking software, but nothing I've found integrates with these products. Anyone know of something that meets these requirements without additional development, or am I stuck putting my business on hold to get this piece in place myself?

  • Update installed on netbook.. now sidebar icons have disappeared! :oS

    - by Lolly Collier
    hope someone can help. I am not extremely computer literate and my brother installed Ubuntu on my Acer net book when my windows crashed irretrievably . I recently (day before yesterday) had a box come up saying an update (i think it was 10 or 11 .something) i followed the instructions to download and install it and now, all my side bar icons have disappeared. I happened upon an Internet connection by chance and have no idea whatsoever how to get them back. This is quite probably a really stupid question and a really easy fix but as i said earlier, i am pretty much a novice, very far from a computer expert! Thanx in advance :o)

  • Cannot install build essential from the CD?

    - by munir
    After a fresh installation of Ubuntu 10.10 I tried to install build-essential from the Ubuntu installation CD. I put the cd in the cdrom and in the software repositories i checked the box install from cd(Ubuntu 10.10 release Maverick Meerkat). Then I reloaded the software repositories. The synaptic manager then tried to download some repository related files but failed to do so as i didn't have internet connection. Then I open a terminal and wrote sudo apt-get install build-essential. It prompted me if I want to install build essential y/N. I typed y but the terminal showed some errors and was not installed. I also tried to add the CD in the software repositories. I clicked add and it prompted me to insert a CD while the CD was still inside the cdrom. I clicked "ok" then and it showed it could not find any cd. What is wrong?

  • Minecraft: Slow performance OUT of the game

    - by blackn1ght
    I downloaded Minecraft yesterday to see what the fuss is about, brilliant game! When playing in Windowed mode, if I try and do anything else, i.e. use the computer, when the game is paused, the computer is incredibly slow, it takes a minute just to type a short message into empathy. Also, once I quit the game, the computer remains slow for about 5 minutes, until it magically frees up and becomes fast again. Could this be related to the 512mb RAM limitation of Java, and the machine is swapping? Even trying to submit this post is incredibly slow and frustrating, it's taking me a minute just to click in the 'Tag's box. Any ideas? Ubuntu 10.10 x64 Intel Q9550 4GB RAM nVidia 8800GTS 320mb (w/prop drivers installed)

  • IIS 6 nested virtual directory redirection

    - by threedaysatsea
    We're running IIS 6 on a WinServer2k3 box and we're having some trouble with the following problem: E-mails were sent out to users asking them to go to the following URL: alias.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue However, the URLS are actually supposed to be: server.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue It's too late to recall all of the e-mails, and we'd like to redirect traffic to make this as seamless as possible for our users. The real problem here is that the server (server.contoso.com) is hosting the alias (alias.contoso.com) as a redirect thusly, and the existing redirect we need to keep functional: Default Web Site (server.contoso.com) --Directory1 --Directory2 --Directory3 Redirection to Directory3 (alias.contoso.com) --Essentially alias.contoso.com will take the user to server.contoso.com/Directory3 Is there any way to host a separate redirect inside of the existing redirect? We need to keep alias.contoso.com taking the user to server.contoso.com/Directory3 but also make alias.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue point to server.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue Any tips? Is this even possible?
