  • Desktop top is lower than it should be

    - by Idan Arye
    I have a very odd problem with Ubuntu 11.10. Here is a picture of it: The window in the picture is maximized, but for some odd reason it does not cover the entire desktop area. That area of the desktop the window does not cover is a dead area - I also can't drag desktop items to there, though I can drag not-maximized windows to that area. Rebooting doesn't help. The problem started after I configured some windows partitions to automount on startup(though I don't see how that could cause the problem...) Does anyone know a way to fix this?

  • Script at Startup

    - by OttoRobba
    I'm using 10.10 and I need to run a script in order to get a windows-like international keyboard layout - basically, it changes how dead keys work. (Original script from this page http://t.tam.atbh.us/en/win-us-intl-4-linux/ ) Since I can't seem to manage to get it going from boot, I have to run a custom script to launch any application. The script: export GTK_IM_MODULE=xim setxkbmap us intl xmodmap -e 'keycode 48 = dead_acute dead_diaeresis dead_acute dead_diaeresis acute diaeresis' application_name So if I put abiword in the application_name, it runs abiword respecting the keyboard script. Ideally, the original script would start at boot and then any applications I use would function with it - just like what happens if I run it first in Terminal (without the app_name line) and then run apps from it. I tried to make the script run from boot by adding it to /etc/rc.local but to no avail. Tried to add it to init.d but that also didn't work. If anyone can help, I'd be most grateful.

  • Do you start migrating your Swing project to JavaFX

    - by Yan Cheng CHEOK
    I have a 4 years old project which is written in Swing + SwingX. Currently, it is still alive and still kicking. However, as more GUI related feature requests coming in (For instance, a sortable tree table), I start to feel the difficulty in fulling the requests. This is true especially there isn't active development going around SwingX project. Also, I hardly can find any good, yet being actively maintained/ developed/ evolving GUI Java framework. I was wondering, any of Swing developers feel the same thing? Have you start to migrate your Swing project to a much more active developed GUI framework like JavaFX?

  • How to Fix a Stuck Pixel on an LCD Monitor

    - by Chris Hoffman
    Have you ever noticed that a pixel – a little dot on your computer’s LCD monitor – is staying a single color all of the time? You have a stuck pixel. Luckily, stuck pixels aren’t always permanent. Stuck and dead pixels are hardware problems. They’re often caused by manufacturing flaws – pixels aren’t supposed to get stuck or die over time.

  • Azure Blob storage defrag

    - by kaleidoscope
    The Blob Storage is really handy for storing temporary data structures during a scaled-out distributed processing. Yet, the lifespan of those data structures should not exceed the one of the underlying operation, otherwise clutter and dead data could potentially start filling up your Blob Storage Temporary data in cloud computing is very similar to memory collection in object oriented languages, when it's not done automatically by the framework, temp data tends to leak. In particular, in cloud computing,  it's pretty easy to end up with storage leaks due to: Collection omission. App crash. Service interruption. All those events cause garbage to accumulate into your Blob Storage. Then, it must be noted that for most cloud apps, I/O costs are usually predominant compared to pure storage costs. Enumerating through your whole Blob Storage to clean the garbage is likely to be an expensive solution. Lokesh, M

  • What is the intention behind asking weight of plane?

    - by AKS
    I was asked this question "How would you find weight of Aeroplane" in an interview and I am not sure why this question was one of the two question asked in the interview. I tried to answer it using all possible ways but could not give the correct answer.(found the correct answer after google search) How much such questions decide your selection in the interview? Here was my approach: 1. If measurement of plane is given then i will calculate volume and multiply by density, will consider fuel weight plus other dead weight. 2. Using water displacement method if i can put plane in water and somehow measure how much water is displaced. But found using google search that right approach was to put place on a ship and mark the level of water on the hull, then remove plane and then ship will go up. And start putting weight on the ship till marked hull reaches the water level.

  • Touchpad stopped working after suspend, never woke up again

    - by Luca
    I have a Toshiba L650, installed (dual boot) Ubuntu 10.10. Touchpad worked fine until I tried for the first time to suspend (I closed the screen on the keyboard). The system never woke up again. Reset (battery disconnected and then reconnected), restart of the system, disk checks, and so on. After that, everything works fine except the Touchpad, completely dead. Rebooted again. The problem persists. Any hints? Thanks, Luca.

  • Which simple Java JPA ORM tool to use ?

    - by Guillaume
    What Java ORM library implementing JPA that match following criteria would you recommend and why ? free & open source alive (at least bug fixes and a mailing list) with good documentation simple (simpler than hibernate) I need to select a simple ORM tool that can be set up in minutes, without too much configuration and easy to understand, for setting simple CRUD DAOs. A query builder will be an interesting plus. Later I can have to move to Hibernate, that's why being JPA compliant is a must. I have found some candidates on the web, but not so much feedback, so I will gladly take your advices on the topic. ----- EDIT --------- I have been successfully testing ebean/avaje with a small test cases. Any one has a feedback on using these tools in production ?

  • Twitter Storm VS. Google's MapReduce

    - by Edward J. Yoon
    IMO, the era of Information Retrieval is dead with the advent of SNS. And the question type is changed from "How many backlinks your site has?" to "How many people have clicked URL you've shared on SNS?". So many people who newbie in Big Data Analytics often asks me "How can I analyze stream data time-series pattern mining methods using Map/Reduce?", "How can I mining the valuable insights using Map/Reduce?", "blah~ blah~ using Map/Reduce?". The answer is No Map/Reduce.

  • Tracking QR Code referrals

    - by Vince Pettit
    We were using a third party website to provide QR codes and track them, the only problem was one week their server went down for some time and effectively killed the QR code off as it was a dead link. As far as I could see their tracking was a simple redirect via their website. I have set up a page with a javascript redirect to the destination URL with our Google analytics code in the page but was just wondering if anyone else has had any experience of setting up their own tracking/redirect for QR codes this way or have you done it differently?

  • 301 redirecting a blog's RSS feed URL?

    - by Marc Charbonneau
    I moved my personal blog from Wordpress to Ghost this weekend, which changes the RSS feed URL from /feed/ to /rss/. By default Ghost returns a 301 redirect for /feed/, which I've verified by checking the response header and looking at the logs: In Feedly though, new posts aren't being picked up (at least after 24 hours. I'm not sure if they might have a waiting period before updating the URL). What's the correct thing to do in this situation? Do I need to keep /feed/ alive instead of returning a 301? If so, is there a rewrite rule that would let me do this in nginx instead of having to modify the Ghost source code?

    HEHE it's a stupid problem, for those who care place the following on the load event of the master page or default             Response.AppendHeader("Cache-Control", "no-cache"); //HTTP 1.1             Response.AppendHeader("Cache-Control", "private"); // HTTP 1.1             Response.AppendHeader("Cache-Control", "no-store"); // HTTP 1.1             Response.AppendHeader("Cache-Control", "must-revalidate"); // HTTP 1.1             Response.AppendHeader("Cache-Control", "max-stale=0"); // HTTP 1.1              Response.AppendHeader("Cache-Control", "post-check=0"); // HTTP 1.1              Response.AppendHeader("Cache-Control", "pre-check=0"); // HTTP 1.1              Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.1              Response.AppendHeader("Keep-Alive", "timeout=3, max=993"); // HTTP 1.1              Response.AppendHeader("Expires", "Mon, 26 Jul 1997 05:00:00 GMT"); // HTTP 1.1   It finally worked for me:)

  • Is there an open source sports manager project?

    - by massive
    For a long time I've tried to search for an open source manager game, but without any luck. I'm looking for a suitable project for a reference to my own pet project. Features like well designed data model, tournament and fixture generation and understandable match simulation algorithm would be a great bonuses. I'm especially interested in game projects like Hattrick and SI Games' Football Manager, although it is irrelevant what the particular sport is. The project should be preferably web-based as Hattrick is. I've crawled through GitHub and SourceForge, but I found only a few sports simulation projects. Projects, which I have found, were either dead or not fulfilling my wishes. Do you know any open source manager game / fantasy sports game project, which would be available as open source, OR at least any material, which would be useful when building a such project?

  • SharePoint Client Object Model: Step One

    - by PeterBrunone
    I almost didn't make it out alive.  I followed the instructions in every piece of sample code and every forum post by someone who had no idea why their client OM code wasn't working, and my code still wouldn't get past the page load.  I kept getting "'Type' is undefined" errors when sp.core.js tried to register the SP namespace.As it turns out, you need the help of the default master page (or one like it) to get the object model loaded.  Once I told my sample page to use the default master and modified everything accordingly, it hooked up and ran just fine.Now I can finally get some work done.

  • Rationale behind freeware projects

    - by VexXtreme
    I've seen some freeware projects in the past where the author(s) invested a significant amount of their personal time and resources and never even considered charging for the software. A lot of these projects were donation based, and from what I've heard, donationware can never be a viable business model (even to simply support development costs) because most people choose not to donate if given an option. A lot of these projects eventually shut down because their authors could not sustain them further. Granted, some people simply like making the community happy (or something), but if you're struggling to keep your project alive, why not charge some small amount such as $10 simply to stay operational? If people find your software useful (and a lot of people found those projects VERY useful) they won't have a problem paying such a small amount. The question is: if you have a popular app that people like and download in great numbers, why not put a price tag on it? Why do it for free?

  • Software developer needs Validation for VA Chap 31 to purchase Macbook Pro vs. PC [closed]

    - by David
    I am currently attending college with a path of software development and working towards my BS thanks to VA Chap 31. My old original Macbook Pro is near dead and no longer upgradable on the software or hardware side. The VA has offered to purchase a PC laptop for me (Because my syllabi says computer required), but I do not want to go backwards. I have a lot invested in OS X software and Mac peripherals, not to mention I prefer to program in an Apple environment. PC vs. Mac costs are so drastically different that I must validate my request for a new Macbook Pro. In my request to the VA, I stated the above and some other topics but they requested more validation. Can anyone recommend issues, reasons, etc. to help me validate this purchase by the VA for school? Thanks in advance for your help, David

  • Drawing an animation over an already drawn screen

    - by Chandan Pednekar
    I am working on a XNA WP7 card game whose basic prototype is complete. In game screen, 6 cards are displayed at a time (3 for each of the two players say 1,2 and 3). If player A attacks one of player B's card then I want to show an animation over player B's card i.e the victim card(say a claw scratch for e.g.) My question is how do I approach with the animation system so that I can draw an animation over a card upon certain events e.g. dead, fire, claw attack etc. I have an attack function which detects which type of card is attacking which type of card. Depending on the type of attacker card I want to display the animation on the victim card. Can I call animation classes function for different animations in the attack function itself without actually having to call separate draw and update functions. If so, how? Also how do I play sound at the same time when the animation is going on?

    Using Webmin ? Network Configuration, I added a new DNS address to the existing server (10.100.200.300). While I saved the new configuration, I lost access to webmin and ssh to this server. How can I retrieve access? I pinged 10.100.200.300 and its dead. When I tried to login with ssh it says: error no route to host. I usually log in to webmin the server IP address and port 10000 but now I cannot. Any help to go back to my previous state?

  • What is the role of C++ today?

    - by hades
    Currently I'm an IT student and I'm wondering what is still important in C++ today, what for is it used? I completed basic C++ course in my university but I can't imagine where can I use my knowledge and in which direction should I go learning C++. In other words what should I learn to become a successful C++ programmer? Currently I'm learning Java just because I don't see clearly in which area C++ could be useful today, but I clearly know which kind of work I'll be doing as a Java programmer. But I still hope that C++ isn't dead.

  • Moving from XNA/C# to DirectX/C++ quite confused

    - by misiMe
    I made some game with XNA/C# for Windows Phone and Windows 8, since XNA is dead and Visual studio doesn't support it (I have to target Windows Phone 7.1 to build with XNA), I want to start learning something more "consistent in time" and improve my skills. I'm a little confused about the possibilities, because C++/DirectX alone seems difficult, so I found some high-level classes to help: DirectX Toolkit Cocos2D My questions are: What will happen when they will "die" like XNA? Is C++'s approces more "professional" than C#/XNA and why? Is C++'s approces more "portable"? Is C++'s approces more resistant in terms of time? Is there any consideration about DirectX TK and Cocos2D in terms of performance? I ask that because I found that every Game software house in my country looks for skilled C++ programmers.

  • My Feelings About Microsoft Surface

    - by Valter Minute
    Advice: read the title carefully, I’m talking about “feelings” and not about advanced technical points proved in a scientific and objective way I still haven’t had a chance to play with a MS Surface tablet (I would love to, of course) and so my ideas just came from reading different articles on the net and MS official statements. Remember also that the MVP motto begins with “Independent” (“Independent Experts. Real World Answers.”) and this is just my humble opinion about a product and a technology. I know that, being an MS MVP you can be called an “MS-fanboy”, I don’t care, I hope that people can appreciate my opinion, even if it doesn’t match theirs. The “Surface” brand can be confusing for techies that knew the “original” surface concept but I think that will be a fresh new brand name for most of the people out there. But marketing department are here to confuse people… so I can understand this “recycle” of an existing name. So Microsoft is entering the hardware arena… for me this is good news. Microsoft developed some nice hardware in the past: the xbox, zune (even if the commercial success was quite limited) and, last but not least, the two arc mices (old and new model) that I use and appreciate. In the past Microsoft worked with OEMs and that model lead to good and bad things. Good thing (for microsoft, at least) is market domination by windows-based PCs that only in the last years has been reduced by the return of the Mac and tablets. Google is also moving in the hardware business with its acquisition of Motorola, and Apple leveraged his control of both the hardware and software sides to develop innovative products. Microsoft can scare OEMs and make them fly away from windows (but where?) or just lead the pack, showing how devices should be designed to compete in the market and bring back some of the innovation that disappeared from recent PC products (look at the shelves of your favorite electronics store and try to distinguish a laptop between the huge mass of anonymous PCs on displays… only Macs shine out there…). Having to compete with MS “official” hardware will force OEMs to develop better product and bring back some real competition in a market that was ruled only by prices (the lower the better even when that means low quality) and no innovative features at all (when it was the last time that a new PC surprised you?). Moving into a new market is a big and risky move, but with Windows 8 Microsoft is playing a crucial move for its future, trying to be back in the innovation run against apple and google. MS can’t afford to fail this time. I saw the new devices (the WinRT and Pro) and the specifications are scarce, misleading and confusing. The first impression is that the device looks like an iPad with a nice keyboard cover… Using “HD” and “full HD” to define display resolution instead of using the real figures and reviving the “ClearType” brand (now dead on Win8 as reported here and missed by people who hate to read text on displays, like myself) without providing clear figures (couldn’t you count those damned pixels?) seems to imply that MS was caught by surprise by apple recent “retina” displays that brought very high definition screens on tablets.Also there are no specifications about the processors used (even if some sources report NVidia Tegra for the ARM tablet and i5 for the x86 one) and expected battery life (a critical point for tablets and the point that killed Windows7 x86 based tablets). Also nothing about the price, and this will be another critical point because other platform out there already provide lots of applications and have a good user base, if MS want to enter this market tablets pricing must be competitive. There are some expansion ports (SD and USB), so no fixed storage model (even if the specs talks about 32-64GB for RT and 128-256GB for pro). I like this and don’t like the apple model where flash memory (that it’s dirt cheap used in thumdrives or SD cards) is as expensive as gold (or cocaine to have a more accurate per gram measurement) when mounted inside a tablet/phone. For big files you’ll be able to use external media and an SD card could be used to store files that don’t require super-fast SSD-like access times, I hope. To be honest I really don’t like the marketplace model and the limitation of Windows RT APIs (no local database? from a company that based a good share of its success on VB6+Access!) and lack of desktop support on the ARM (even if the support is here and has been used to port office). It’s a step toward the consumer market (where competitors are making big money), but may impact enterprise (and embedded) users that may not appreciate Windows 8 new UI or the limitations of the new app model (if you aren’t connected you are dead ). Not having compatibility with the desktop will require brand new applications and honestly made all the CPU cycles spent to convert .NET IL into real machine code in the past like a huge waste of time… as soon as a new processor architecture is supported by Windows you still have to rewrite part of your application (and MS is pushing HTML5+JS and native code more than .NET in my perception). On the other side I believe that the development experience provided by Visual Studio is still miles (or kilometres) ahead of the competition and even the all-uppercase menu of VS2012 hasn’t changed this situation. The new metro UI got mixed reviews. On my side I should say that is very pleasant to use on a touch screen, I like the minimalist design (even if sometimes is too minimal and hides stuff that, in my opinion, should be visible) but I should also say that using it with mouse and keyboard is like trying to pick your nose with boxing gloves… Metro is also very interesting for embedded devices where touch screen usage is quite common and where having an application taking all the screen is the norm. For devices like kiosks, vending machines etc. this kind of UI can be a great selling point. I don’t need a new tablet (to be honest I’m pretty happy with my wife’s iPad and with my PC), but I may change my opinion after having a chance to play a little bit with those new devices and understand what’s hidden under all this mysterious and generic announcements and specifications!

  • Interpolating between two networked states?

    - by Vaughan Hilts
    I have many entities on the client side that are simulated (their velocities are added to their positions on a per frame basis) and I let them dead reckon themselves. They send updates about where they were last seen and their velocity changes. This works great and other players see this work find. However, after a while these players begin to desync after some time. This is because of latency. I'd like to know how I can interpolate between states so they appear to be in the correct position. I know where the player was LAST seen and their current velocity but interpolating to the last seen state causes the player to actually move -backwards-. I could not use velocity at all for other clients and simply 'lerp' them towards the appropriate direction but I feel this would cause jaggy movement. What are the alternatives?

  • How to stop getting too focused on a train of thought when programming?

    - by LDM91
    I often find myself getting too focused on a train of thought when programming, which results in me having what I guess could be described as "tunnel vision". As a result of this I miss important details/clues, which means I waste a fair amount of time before finally deciding the path I'm taking to solve the task is wrong. Afterwards, I take a step back which almost always results in me discovering what I've missed in a lot less time.. It's becoming really frustrating as it feels like I'm wasting a lot of time and effort, so I was wondering if anyone else had experienced similar issues, and had some suggestions to stop going down dead ends and programming "blindly" as it were!
