• Develop for Desktop and mobile use?

  - by ran2

  I am in the very beginning of developing an app / desktop program. I want it to be cross-platform and possibly also as a tablet version (preferably Android Icecream sandwich). Note that I need to run it offline. I thought about the following approaches: ADOBE Air, since I do not need much performance. Plus I did some web programming in the past which might be of some use. Afaik it would run on OS X and Windows and should run on mobile OSes, too. Qt. Found some nice Qt based desktop recently and read it also works on android. Plus I like the SDK. HTML5 / JS. Again my web background should help me here. I wont need no sever side scripts, thus it should work without installing anything but a browser. How easy could this be converted into an Android app? There might be a plethora of other (better) ways to do it, but I haven't thought of them yet. Can you help out? How would you create such an application. Would it be better to do some pure desktop client and then create tablet versions? Would you rather start to create a website and worry later on how to turn into an app?

• How do I debug an overheating problem?

  - by Tab

  Hello guys. I have a problem with my Laptop (Dell Inspiron 1564 Core i5 4GB Ram VGA ATI Mobility Radeon HD 4300 running Ubuntu 10.10 32bit). It shuts down abruptly without even a lag in the application I am working with before shutdown. I think it's overheating problem. Actually the laptop is hot all the time when I am running Ubuntu. When I switch back to windows, even with intense load it won't shutdown or show any problem as long as I keep proper ventilation (when the air openings are blocked it does the same). Actually on Ubuntu i don't usually do things that need much CPU power, usually surfing internet, coding web pages and sometimes playing with python and ruby. I am not enabling desktop effects so no GPU load except the normal GNOME gui. Now as I am writing the Processor load in the panel monitor applet is 0%, Memory 11% by programs, 22% by cache. And i have CPU Frequency monitor for each of the 4 cores set to 1.20 Ghz (the lowest possible value, i am not sure if this applet does really limit CPU usage). Running sensors in terminal gave me temp1: +26.8°C (crit = +100.0°C) temp2: +0.0°C (crit = +100.0°C) hddtemp /dev/sda at the terminal gave me /dev/sda: WDC WD3200BEVT-75ZCT2: 46°C All that fine but the laptop is Really hot i can feel it in the keyboard, mouse pad is painful to touch, and the fan is always spinning. I am also placing 2 small fans running on USB under the laptop right now and the laptop is lifted over the fans so it's well ventilated. When I am running windows it doesn't get that hot except when there is a really big load on the CPU and this is keeping me away from using Linux for everyday tasks. Actually I don't care much for speed as I can deal with low speed it's not going to shutdown abruptly. So please if you can help me and tell me what are the possible causes, where should I start ?

• Can you open an SPSite object while being within a different site collection?

  - by Chris Stewart

  I'm working on creating a common navigation experience across two site collections in MOSS 2007. I've looked around for various solutions and haven't found anything that fits. Our navigation is dynamic and driven by a number of factors, including audience targeting. Most of what I've found relates to having static XML and that just won't work for our requirements. What I'm down to at the moment is just getting a navigation item from site collection A while in the context of site collection B. Are there reasons I shouldn't be able to just open a navigation item from site collection A and gets its audience? Certainly there could be permissions problems on my end, or code related issues, or things that are in my control. What I'm wondering is if there's something inherent to SharePoint that would not allow this. Something I don't have control over which would force me to travel a different path.

• Calcualting Optimal Site to Site Routing using pre-computed times between sites

  - by Idistic

  Assume that I have a number of sites (locations) and the time it takes to travel from each site to each site is pre-computed Example Data - Site to Site Pre-Calculated Times in minutes From Start Site To A 20 To B 15 To C 15 From Site A To B 10 To C 15 Site B To A 10 To C 20 Site C To A 15 To B 20 4 Sites is fairly simple, but what if the site set was say 1000 sites? Given a large site set What would the best approach be to quickly find the optimal routes from the start site while visiting every other site just once? Route Solutions from Start Site for 3 sites from a start site 1 A(20) B(10) C(20) = 50 2 A(20) C(15) B(20) = 55 3 B(15) A(10) C(15) = 40 4 B(15) C(20) A(15) = 50 5 C(15) A(15) B(10) = 40 6 C(15) B(20) A(10) = 45

• Is Oracle Database Appliance (ODA) A Best Kept Secret?

  - by Ravi.Sharma

  There is something about Oracle Database Appliance that underscores the tremendous value customers see in the product. Repeat purchases. When you buy “one” of something and come back to buy another, it confirms that the product met your expectations, you found good value in it, and perhaps you will continue to use it. But when you buy “one” and come back to buy many more on your very next purchase, it tells something else. It tells that you truly believe that you have found the best value out there. That you are convinced! That you are sold on the great idea and have discovered a product that far exceeds your expectations and delivers tremendous value! Many Oracle Database Appliance customers are such larger-volume-repeat-buyers. It is no surprise, that the product has a deeper penetration in many accounts where a customer made an initial purchase. The value proposition of Oracle Database Appliance is undeniably strong and extremely compelling. This is especially true for customers who are simply upgrading or “refreshing” their hardware (and reusing software licenses). For them, the ability to acquire world class, highly available database hardware along with leading edge management software and all of the automation is absolutely a steal. One customer DBA recently said, “Oracle Database Appliance is the best investment our company has ever made”. Such extreme statements do not come out of thin air. You have to experience it to believe it. Oracle Database Appliance is a low cost product. Not many sales managers may be knocking on your doors to sell it. But the great value it delivers to small and mid-size businesses and database implementations should not be underestimated.

• How to tune touchpad for smaller area?

  - by M.L.

  I just purchased the Asus Zenbook UX31A and I require some advice regarding tuning the touchpad. Basically my problem is that the mouse buttons are withing the touch area and I would like it to be disabled. Such that only part of the touch area is recognized. I have attached an image to clarify the idea. Basically only the red area in the image should be recognized. I have two reasons for this request. Firstly, I like to hold my thumb on the mouse button instead of holding it in the air. This is problematic, because touchpad thinks that I'm trying some kind of two finger gesture all the time and cursor stops moving. Clicking is also problematic since every finger movement -- regardless of how insignificant it might be -- on the "button" will move the cursor. I have been playing with some synclient settings like AreaBottomEdge etc. They have some effect but then I cannot highlight text or right button stops working. How could I solve this?

• IRQ Conflicts Causing Video Card and Boot Problems?

  - by sanpatricio

  tl;dr - I have 4 devices sharing 1 IRQ. Is this bad and how do I tell the BIOS to stop it? Background: I have an old Dell GX280 dual Pentium 4 that I (semi) resurrected last weekend with an installation of Ubuntu 12.04. Everything was going fine the first several hours until a problem that plagued me when WinXP was on that machine happened -- it froze. Completely froze. None of the myriad of ways I have found here on askubuntu helped me to regain control except a long-press of the power button to shut it off. Clearly, this wasn't a software/WinXP issue. After much googling, I found that hardware conflicts can often cause this sort of total lock-up and with all the odd blocks of yellow and flecks of color showing on my screen (both WinXP and Ubuntu) I figured my old GeForce 7600 was failing and causing me these odd issues. (A good canned-air dusting of the entire interior fixed the color fleck problem) Again, through much googling and numerous answers found on askubuntu, I somehow stumbled my way onto the lshw command. After going through it, line by line, I found that I have four devices sharing IRQ 16: eth0, wlan0, ide0 (DVD-RW), and my video card. In hindsight, I can recall weird instances of my Ethernet connection to another computer not working when I thought it should. I never full troubleshot those issues so it could be a coincidence. The other thing that has been plaguing me since installing Ubuntu (wasn't there during WinXP) has been periodic moments of my monitor getting no signal from Ubuntu during boot. The first couple days, it would disappear after the Dell boot screen and reappear at Ubuntu login. Now, it disappears after the Dell boot screen and doesn't return at all -- I have to hit F12 where I can load a safe mode version of Ubuntu and get more details like dmesg and lsdev. I also ran memtest86 overnight and woke up to zero errors, so failing RAM is out. Where do I go from here?

• can you use proxies to do load/stress testing on a server, with proxy serving as a sort of mirror?

  - by EndangeringSpecies

  suppose I want to test a server's and its web application's ability to handle many simultaneous connections well and show decent latency. So ideally I would want a thousand machines to bombard it with usage requests, but that's not practicable. So instead, can I just make a testing script with a thousand threads to run on the same server and have them perform the testing, connecting to the server via a geographically far-away proxy? My reasoning here is that the signal will have to travel realistically big distances to the proxy and back, so that sort of emulates the reality of real clients accessing the server. Then again, to take this one step further, are there prepackaged emulators/frameworks that could perform a similar test without using internet at all, just simulating the latency of the network, realistically creating all the socket connections and other resource intensive stuff etc?

• How to react to an office harassment based on my profession ? [closed]

  - by bob from jersey

  A lot of my co-workers (not developers, people from the other departments) who are framing me in the classical "nerd" stereotype, and with that acting disturbing towards me. Of course they are not aggressive or anything, since we are in a work environment having rules on it's own, plus we are all grownups now, but they are on a "quite war" against me (not particularly against me, they are against all developers, but I am the only one who dares to speak about it). I hear names, "nerd", "geek", "cyborg", "outsider" and so on, it's really inappropriate. Of course, nothing is said in our faces, but, you know, "you hear things over". Also this general feeling of "them not liking us at all" can be sensed in the air all the time. And while it is not a problem for a few weeks, a larger duration of constant office harassment (going for months now), can be really annoying and can cause a serious drop in the development performance, which will (inevitably) lead to problems with the management (maybe getting me fired). I want to know, should I continue with my current defensive strategy (passively ignoring their inappropriate labels) or should I switch into a more aggressive maneuvers, like giving them logical reasons why their antisocial behavior should be banned?

• JavaOne Countdown, Are you ready?

  - by Angela Caicedo

  This is a great time of the year!  Not only does the weather start cooling down a bit, but it's time to get ready for JavaOne 2012.  It feels so long since my last JavaOne (last year I missed it because I was on a mom duty), so this year I couldn't be happier to be this close to the action again.  Have you ever been at JavaOne?  There are a million great reasons to love JavaOne, and the most important for me is the atmosphere of the conference: The Java community is there, and Java is in the air! This year we have more than 450 sessions, and there are HOLs (Hands on labs) to get your hands dirty with code.  In addition, there will be very cool demos, an exhibition hall. and a DEMOground.  During the whole time, you will have the opportunity to interact with the speakers, discuss topics and concerns, and even have a drink! Oh yes, I almost forgot, there will be lots of fun even apart from the technology!  For example there will be a Geek Bike Ride, a Thirsty Bear party, and the Appreciation Party with Pearl Jam and Kings of Leon.  How can this get any better! So, are you ready yet?  Have you registered?  If not, just follow this "Register for JavaOne" link and we'll see you there! P.S.  Little known fact: If you are a student you can get your pass for free!!!

• Can I prevent iPhone from using 3G under any circumstances?

  - by dageshi

  I'm writing a travel guide related app that will download large databases (60meg) potentially overseas, with the reachability code I can tell when a host is reachable via wifi or 3g BUT I'm worried that if for some reason the wifi connection breaks for a minute or so as some DSL connections are likely to do on occasion the iphone will switch transparently to 3G and without realising I could be racking up someones phone bill with overseas data charges! So I'm wondering if anyone has any experience, in the event of such break in wifi connectivity (wifi still works but it's connection to the net is down) would the reachability code report ReachableViaWWAN? So I could wait till my download code returns, check how the host is currently reachable and if it's via 3g I could abort? Is it possible to select what type of connection I can use aka 3g or wifi exclusively?

• Acer Aspire 5542G overheating with ubuntu/kubuntu 12.04

  - by james

  I have an Acer Aspire 5542G laptop purchased couple of years ago. All these days, i used windows 7 on it . Then I tried ubuntu 12.04 . Everything was fine except the overheating issue. I updated ubuntu with all security fixes and available updates but nothing solved the problem. With idle use like internet browsing, the cpu fan speeds up a lot and i can feel very hot air coming from the vent (comparable to playing serious 3d game in windows). But it will not go to a point of freeze and shutdown. But as long as im using it, with no intensive tasks at all, the laptop stays too hot. This wasn't the case with windows7. In windows 7 the fan will not rotate at all with normal use. I heard there was manufacturing defect with some acer laptops, but i think it wasn't the case with my laptop since windows7 runs perfectly. I updated the bios to latest version. I cleaned dust in the vents. I tried kubuntu 12.04 up-to-date. Nothing solved the issue. My laptop specs are: CPU : AMD turion2 x2 M500 @ 2.2GHz GPU : AMD Mobility Radeon HD4570 3GB RAM and 320GB hard disk.

• How to create a "dependency graph" for IT assets

  - by p.marino

  One of my customers is trying to create an interactive "matrix" of interdependencies for the various applications used in their company (it's a travel&leisure company with around 2500 employees). The idea (still at the prototype stage) is to create a sort of Map, based on Visio or similar tool, which traces the communication and interdependencies between all the IT assets in the company, so that when someone asks for a change they can get an overview of the impacts. This was mentioned in a casual setting and it will not be my responsability to directly work on this, but I did contribute the little I know already in terms of vaguely related methodologies (Zachman Framework). I'd like to hear from the people in here if they know of methodologies, or tools, that may help this kind of effort, and if they have any specific experience to contribute. I'll digest the answers and send the result back to my customer, hoping this may be of some help with their task (which I consider a bit visionary and prone to all the pitfalls of any documentation project, but still well worth pursuing).

• Weekend Project: Build a Fireball Launcher

  - by Jason Fitzpatrick

  What’s more fun than playing with fire? Shooting it from your hands. Put on your robe and wizard hat, make a stop at the hardware store, and spend the weekend trying to convince your friends you’ve acquired supernatural powers. Over at MAKE Magazine, Joel Johnson explains the impetus for his project: A stalwart of close-quarter magicians for years, the electronic flash gun is a simple device: a battery-powered, hand-held ignitor that uses a “glo-plug” to light a bit of flash paper and cotton, shooting a fireball a few feet into the air. You can buy one from most magic shops for around $50, but if you build one on your own, you’ll not only save a few bucks, you’ll also learn how easy it is to add fire effects to almost any electronics project. (And what gadget couldn’t stand a little more spurting flame?) The parts list is minimal but the end effect is pretty fantastic. Hit up the link below for the full build guide, plenty of warnings, and a weekend project that’s sure to impress.

• Set a 2d camera's position so that a building is under the players feet

  - by Potato

  My issue is this: i am making a scrolling game in XNA, and the camera updates based on the players velocity, but the player never actually moves, he is always in the center of the screen. When he hits the top of the building though i want him to always be on top and sink through the texture in a way like this: what i am doing to make this happen is i am just setting his velocity to 0, so its not moving, but the more velocity he hits a building with the more he sinks through it. I also tried setting the buildings position to the plays Bounding Box's bottom, and this achieved the look i wanted but this also resulted in the other buildings rising in the air, because the velocity was still moving (even if i set it to 0). if it was not a scrolling game, this would be not a problem, because you just set the players position to the top of the building, but because the player never actually moves, i actually need to move the camera to the point where the building is under the players feet without the other buildings rising. (Take note this is note a real camera, it is just a class that moves the objects in the world based on the players velocity). All questions are welcome.

• 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.

• Traffic consumed by Team Foundation Server 2010

  - by micha12

  We are currently selecting a source control and issue tracking software, and are looking towards Team Foundation Server 2010. Some participants of our project often have slow Internet connection (for example during travel), and therefore it is important for us to have a source control system that does not consume too much traffic. I was unable to find information on traffic consumption when using TFS 2010. Does anyone has such info? Does TFS 2010 support traffic compression? Do other source control systems (like SVN, for example) produce less or more traffic than TFS 2010?

• OGRE 3D: How to create very basic gameworld [on hold]

  - by skiwi

  I'm considering trying around to create an FPS (First person shooter), using the Ogre 3D engine. I have done the Basic Tutorials (except CEGUI), and have read through the Intermediate Tutorial, I understand some of the more advanced concepts, but I'm stuck with very simple concepts. First of all: I would want to use some tiles (square ones, with relative little height) as the floor, I guess I need to set up a loop to get those tiles done. But how would I go about creating those tiles exactly? Like making it to be their own mesh, and then I would need to find some texture. Secondly: I guess I can derive the camera and movement functions from the basic tutorial. But I'll be needing a "soldier" (anything does for now), what is the best way to create a moderately decent looking soldier? (Or obtain a decent one from an open library?) And thirdly: How can I ensure that the soldier is actually walking on the ground, instead of mid air? Will raycasting into the ground + adjust position based on that, suffice?

• How to Use Vim-Style Keyboard Shortcuts for OS X Tab Navigation

  - by The Geek

  After switching to OS X when I got a new MacBook Air, one of the first things I needed to duplicate was my extremely customized AutoHotkey setup — the most important of which is using the J and K keys to navigate throughout tabbed windows easily. Yeah, I’m a Vim user. I’ve never been a fan of having to use CTRL + TAB to switch from one tab to the next — to start with, you have to move your hands from the home row, and it’s awkward, and why should I have to do that just because somebody decided that keyboard shortcut before tabs became popular? If you think about it, if tabbed browsers were popular back when keyboard shortcuts were being invented, they would have definitely reserved some of the good shortcuts for switching tabs. On Windows, I’ve always used an AutoHotkey script to make things the way I wanted it:  ALT + J and ALT + K for selecting previous and next tabs. Once you get used to it, it’s extremely awesome, and so much faster than using CTRL + TAB. Of course, I also hacked CTRL + T and CTRL + W into ALT + T and ALT + W so I could open new tabs and close them without moving my hands from the home row. Over on OS X, it turns out that it’s incredibly simple and easy to use CMD + J and CMD + K for next/previous tab navigation, and it works in most applications that support tabs, like Terminal, Safari, or Google Chrome.

• How do I stop video tearing? (Nvidia prop driver, non-compositing window manager)

  - by Chan-Ho Suh

  I have that problem which seemingly afflicts many using the proprietary Nvidia driver: Video tearing: fine horizontal lines (usually near the top of my display) when there is a lot of panning or action in the video. (Note: switching back to the default nouveau driver is not an option, as its seemingly nonexistent power-management drains my battery several times faster) I've tried Totem, Parole, and VLC, and tearing occurs with all of them. The best result has been to use X11 output in VLC, but there is still tearing with relatively moderate action. Hardware: MacBook Air 3,2 -- which has an Nvidia GeForce 320M. There are two common fixes for tearing with Nvidia prop drivers: Turn off compositing, since Nvidia proprietary drivers don't usually play nice with compositing window managers on Linux (Compiz is an exception I'm aware of). But I use an extremely lightweight window manager (Awesome window manager) which is not even capable of compositing (or any cool effects). I also have this problem in Xfce, where I have compositing disabled. Enabling sync to VBlank. To enable this, I set the option in nvidia-settings and then autostart it as nvidia-settings -l with my other autostart programs. This seems to work, because when I run glxgears, I get: $ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 303 frames in 5.0 seconds = 60.500 FPS 300 frames in 5.0 seconds = 59.992 FPS And when I check the refresh rate using nvidia-settings: $ nvidia-settings -q RefreshRate Attribute 'RefreshRate' (wampum:0.0; display device: DFP-2): 60.00 Hz. All this suggests sync to VBlank is enabled. As I understand it, this is precisely designed to stop tearing, and a lot of people's problem is even getting something like glxgears to output the correct info. I don't understand why it's not working for me. xorg.conf: http://paste.ubuntu.com/992056/ Example of observed tearing::

• Database design question

  - by Lijo

  Hi Team, I have an interesting database design problem that I formulated while travelling by a bus, coming back from my home. Design a normalized database for a bus ticketing system (not reservation system). In each trip, the conductor of the bus will give tickets to its passengers after collecting fare from them. Passengers travel from a various source places to various destination places. The system must be able to give a report of the places for which the number of passengers was more than 2. Suppose the stops for the bus are L1,L2, L3 and L4 Suppose passenger P1 travels from L1 to L4. P2 travels from L2 to L4. P3 travels from L3 to L4. The report should list only (L3-L4) for which it has more than 2 travelers. Can you please help me to solve the following problems 1) Design a normalized database 2) Write a query for the report 3) Is there any site that gives these kinds of interesting database design questions and answers? Thanks Lijo

• Is it reasonable to null guard every single dereferenced pointer?

  - by evadeflow

  At a new job, I've been getting flagged in code reviews for code like this: PowerManager::PowerManager(IMsgSender* msgSender) : msgSender_(msgSender) { } void PowerManager::SignalShutdown() { msgSender_->sendMsg("shutdown()"); } I'm told that last method should read: void PowerManager::SignalShutdown() { if (msgSender_) { msgSender_->sendMsg("shutdown()"); } } i.e., I must put a NULL guard around the msgSender_ variable, even though it is a private data member. It's difficult for me to restrain myself from using expletives to describe how I feel about this piece of 'wisdom'. When I ask for an explanation, I get a litany of horror stories about how some junior programmer, some-year, got confused about how a class was supposed to work and accidentally deleted a member he shouldn't have (and set it to NULL afterwards, apparently), and things blew up in the field right after a product release, and we've "learned the hard way, trust us" that it's better to just NULL check everything. To me, this feels like cargo cult programming, plain and simple. A few well-meaning colleagues are earnestly trying to help me 'get it' and see how this will help me write more robust code, but... I can't help feeling like they're the ones who don't get it. Is it reasonable for a coding standard to require that every single pointer dereferenced in a function be checked for NULL first—even private data members?

The only reason it is passed into the constructor is so PowerManager can be tested with a mock IMsgSender subclass.
