  • What is supposed to happen when you install Gmail webapp?

    - by ubuntico
    I have installed Gmail (and other Google as well) webapps into Ubuntu 14.04 64-bit. After that I rebooted the system hoping that webapps will integrate into the system. But after logging back to the system, I see no changes. If I click on email envelope (top bar), I don't see my inbox. Also if I try to search email in Dash via gmail keyword, nothing happens as well. Am I using this wrongly or webapps don't work? What was supposed to happen when I install webapps? Note: I did start the Gmail app from Dash and logged in

  • Disabled WiFi but it keeps re-enabling itself; want it to stay disabled

    - by Mike Uresti
    I have an Alienware X51 desktop with a wireless card, I have it connected via ethernet and want to permanently disable WiFi from ever using itself. When running Windows, I go to device manager and rightclick-disable the Wireless card and that takes care of my problem. Is there a similar method using Ubuntu 14.04? For now, I click on the network icon in the system tray and uncheck 'Enable wifi' but it seems to turn itself back on as I use my computer, I think I have the incident isolated to something with Steam. It seems like after I start the Steam client it always is re-enabled. Hopeful answer: Just disable/remove/block wireless card from ever working.

  • How much should I rely on Visual Studio's Auto Generated Code?

    - by Ant
    So I'm reading up on ASP.NET with VB.NET and I want to start making my own, professionally built website using ASP. I'm wondering though; I'm still using the basics so I'm really just a novice, but how much should I rely on Visual Studio to create my elements? Should I make my own text boxes and have my own login routine, or should I just use ASP's login features? I know eventually you have to use your own classes and such which is where the real coding comes in, but I'm not sure how relaible, flexible and secure the pre-wrote elements are? Any help would be greatly appreciated.

  • How do you change your screen's color temperature in Ubuntu?

    - by RPG Master
    I edit my photos on my laptop (yes, I know they have crap displays) and I recently had to replace the screen because the old one just randomly died. The old one had decent color reproduction by default, but this new one is VERY blue. After playing with the Gamma I've gotten it to be a bit better, but it's still pretty blue. So, my question is, how do I go about changing my laptop's display's color temperature? And I don't mean through something like the Red, Green, Blue sliders in the NVIDIA config menu. I'm talking about like adjusting in degrees, like editing a photo's white balance. EDIT: So now I've found Redshift and it's doing me pretty good. I thought it might be helpful if I out here the command I'm using. redshift -t 5000:5000 -g .5 By adding this to my start up commands I should be good. I'm still open to other suggestions, because I'd like something that actually edited my xorg.conf or something like that.

  • Additional Drivers error installing in Ubuntu 12.04 (wireless internet and software modem)

    - by gabiro
    I've already search for similar problems but they are so different from mine. these are the drivers http://db.tt/qFZlD5JD I'm having problem with this Additional Drivers once I click the Activate button it will start in downloading and installing but after that it will say Installation failed. Then the "Enable Wireless" will not be available. With the Software Modem issue is the same problem with the Broadcom. These drivers are working on Ubuntu 9 and 11 if I'm not mistaken. Only on 12.04 is not working. One more thing these drivers will enable the Huawei E165g E220. I've already tried other solution for the Huawei to activate but all didn't work. After a restart Enable wireless becomes okay, though. To all Ubuntu experts and masters please I'm begging for help. A million Thank You!.

  • How do I get "ruby" to do what "ruby1.9.1" does?

    - by Daniel
    I want to start off by saying... I really don't need to be using 1.9.2. I understand that you don't ever, ever use Python 3.2, so if the common advice is that I should use 1.8, I'll do that. But don't tell me to do that because it's easier. Whatever version I should be using, though, the question is still relevant: What's a good way to make one command do another command? (I suppose I could write a c program to launch ruby1.9.1, call the executable ruby, and put it in my bin, but this seems like less than a good idea)

  • Do subdomains need to be defined through domain registrar?

    - by Johnny
    I have bought a new domain name from GoDaddy. Let's say it is abcd.com. On GoDaddy's DNS Managing page, I changed A(Host) part to @ = 74.125.232.215 which is www.google.co.uk's IP address. Now if I type www.abcd.com, it directly goes to www.google.co.uk. But if I type http://test.abcd.com, it cannot be loaded. Do I need to define every subdomain through GoDaddy? Is this how it works? P.S. Amazon EC2 directly generates a subdomain for users to reach their virtual PCs. It cannot be domain registrar dependant. P.S.2. Same question for using "www2" at the start of url.

  • Programming Challenges for a beginner

    - by JMK
    I'm in an unusual situation. A colleague of mine wants to "learn programming" and, being a developer I have been tasked with teaching him "programming". Personally, I am self taught, and have never taught any sort of skill to anybody else before so I am not quite sure where to start. Also, I still have a heck of a lot to learn myself (although don't we all)! I write in C# but is C# a good language for a beginner? I was thinking that Visual Basic .Net would be a better starting point, so was considering getting him setup with Visual Studio Express 2010, teaching him a few basics (variables, functions, classes etc) then finding some programming challenges and asking him to work through these. Does anybody have a good source of these sorts of challenges? Also is this a good strategy? Finally, what are your experiences of teaching programming to somebody else and what advice would you give?

  • Is programming in layers real?

    - by Aura
    I am fairly new in product development and I am trying to work over a product. The problem that I have realized is that people draw diagrams and charts showing different modules and layers. But as I am working alone (I am my own team) I got a bit confused about the interaction I am facing in the development within the programs and I am wondering whether developing a product in modules is real or not? Maybe I am not a great programmer, but I see no boundaries when data start to travel from frontend to backend.

  • Part-time work as a beginner programmer [on hold]

    - by Valentas
    I wrote to one company near my university (starting in September) and they responded that they will probably hire me from the work I have already done (some projects and Euler problems solving). It's for 15 hours/week or so in order to not fall behind uni work. They require Python, SQL, XML and a good idea about how the Web works. The job role involves acquiring data from the Web and supplying it as search results for flight seekers (people). I am eager to learn but still, what can I do to become prepared for this? I ask because I tend to gravitate from one technology to the other, trying out things but never mastering it properly. What Web technologies are involved in such a job role? I have two months and want to learn as much as possible because there is much info but I have no idea where to start.

  • Is acoustic fingerprinting too broad for one audio file only?

    - by IBG
    We were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music. Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms): Always-on app for listening Compare the audio patterns to a single audio file (assume sound is a simple beep) If beep is detected, send notification to server With a flow this simple, do you think acoustic fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start? We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.

  • Installed 7zip. Not working. And when removing, it says to remove Fileroller as well

    - by rainlover
    I installed 7zip today from software centre but it won't showed up in launch bar (side bar). I did a lot but failed to open 7zip "window" from any where. I clicked it in dash but then I was sent to software center showing that it is installed. I just don't know how to start it. Nor it is showing in right-click menu. I actually wanted to open flareget which is in .tar.gz. Ubuntu's default archive opener isn't opening it and showing me this: And if I try to remove 7zip, it's saying file-roller should also be removed: What's going on and what's solution?

  • SEO for images: can I use a different (cookieless) domain?

    - by Oliver
    Hello, We want to increase the value of some of our important images by means of SEO, and we want to start serving them from a different, i.e. cookieless, domain. We want to go from http://www.example.com/images/1234.jpg to http://www.example.com/germany/bavaria/landscape.jpg which can easily be done via URL rewriting. Then on the other hand, we would like to serve the image from a completely different domain, let's say http://www.examplestatic.com/germany/bavaria/landscape.jpg, to save the overhead of sending the cookie from www.example.com. Somehow I feel that this is not a good idea because I move the image away from the content by putting it on a different domain. Can anyone shed some light on this problem? Naturally, I would just use a different subdomain, e.g. img.example.com, but we already use subdomains for languages and our cookies are valid for all subdomains of example.com, so this won't help. I'd really appreciate any hints. Cheers,

  • Architecture for html5 multiplayer game?

    - by Tihomir Iliev
    Hello I want to write a HTML5 multiplayer game in which there are rooms with two players answering a series of questions with 3 possible answers, 10sec/question, which are being downloaded from a server. It will have some ratings and so on. I want to make it as scalable as possible. I wonder what technologies to use to accomplish that. HTML5, CSS3 and JavaScript obviously. But what about the server-side? I have been researching and found that Socket.IO + Node.js + mongoDB would do the job but after doing some more research it maybe not. Can you suggest me some kind of architecture for doing this game? Free technologies, if possible. Or what to read and from where to start in order to understand how to do it. Thanx in advance! P.S. I have an experience with HTML5, CSS3, JavaScript, C#, ASP.NET MVC and relational db's.

  • How much code do you write everyday, *at work*?

    - by Aerovistae
    I'm graduating college, about to start a junior software engineering position, and I've been wondering how much I'm going to be expected to do on what kind of timeline. I mean, in python I can write maybe 500 lines in 8 hours. In C, maybe 200 lines in 8 hours. And that's a big maybe. (I'm f#$*ing terrible with C.) Other languages are somewhere in between. I don't even know if that's ridiculously slow or normal or even good, hence the question. How much code do you write a day? It would be helpful to specify what language/technology you're using, and to make note if there are big differences between them like with myself.

  • R12.0 Cash Management Consolidated Patch Collection (CPC) And R12.1 Cash Management Recommended Patch Collection (RPC)

    - by user793553
    If you have Oracle E-Business Suite's Cash Management (CE) application installed, you'll want to be sure to install the latest CPC (Consolidated Patch Collection) if you are using a R12.0 version of the apps, or the latest RPC (Recommended Patch Collection) for the R12.1 version of the apps. These collections give you all the fixes currently available for known issues in the specified versions of the application, including all of the latest Root Cause Analysis Fixes (RCAs)! What is an "RPC" (for R12.1 users)? Since the release of 12.1, a number of recommended patches for Oracle Cash Management have been made available as standalone patches to help address important business process issues. Adoption of these patches was highly recommended at the time, but not always implemented, so to further facilitate adoption of these patches, Oracle consolidated them into product-specific Recommended Patch Collections (RPCs) - a collection of recommended patches. They were created by Oracle Development with the following goals in mind: Stability: To address data integrity issues that have been identified by Oracle Development and Oracle Software Support as having the potential to interfere with the normal completion of important business processes (such as, period close, etc.). Root Cause Fixes (RCAs): To make available root cause fixes for known data integrity issues. Compact: To keep the file footprint as small as possible to help facilitate the install process and minimize testing. Granular: To compile the collection of patches based on functional areas, allowing a customer to apply multiple RPCs at once, or in phases (based on individual needs and goals). Where to start ALL R12 Cash Management users (R12.0 and R12.1 users) should start with the following Note on My Oracle Support (MOS): Doc ID 1367845.1: R12: Cash Management Recommended Patch Collections It's a great place for important implementation information about both sets of critical patch collections! For R12.1x users R12.1 users should also take a look at the documents below for even more information about the RPC for the R12.1.x versions of the Cash Management application, and other related available RPCs: Note Number  Title                                                                                                      1489997.1 Master Troubleshooting Guide for CE: Reconciliation & Clearing [VIDEO] 954704.1 EBS: R12.1 Oracle Financials Recommended Patch Collections (RPCs) 1316506.1 R12: Oracle CE: Upgrading from R11i to R12.1: Latest Recommended Patches Patch Wizard Utility While a patch may contain several hundred files, the impact on your system may actually be minimal. Patches contain hard prerequisites that are intended to make a patch work on a very low code baseline. The Patch Wizard Utility will give you a detailed analysis of the patch’s impact on your instance BEFORE it’s applied, so you’ll know exactly what to expect from the application. Please refer to Doc ID 976188.1 for more information on this important utility

  • Scenario to illustrate how unit testing leads to better design

    - by Cocowalla
    For an internal training session, I'm trying to come up with a simple scenario that illustrates how unit testing leads to better design, by forcing you to think about things like coupling before you start coding. The idea is that I get the participants to code something first, without considering unit testing, then we do it again, but considering unit testing. Hopefully the code produced second time round should be more decoupled and maintainable. I'm struggling to come up with a scenario that can be coded quickly, yet can still demonstrate how unit testing can lead to better overall design.

  • Chrome keeps crashing after updates

    - by Phil
    I'm a chrome user and an enthusiast but few days ago I made Ubuntu get some updates using Update Manager, then I turned off my notebook and when I restarted it, I tried to start Chrome which after a few seconds turned the screen completely black, and some errors appeared for few seconds and then I got logged off, and had to re-login, and when I opened Chrome again the same thing happened! I've uninstalled it with Synaptic and did complete cleanings before re-installing Chrome but nothing succeeded. Now I can't use either Chromium and Chrome, but Firefox works. It's a very strange thing, never happened to me before and I don't know what to do because I had all my bookmarks syncronized in Chrome! Please help if you can :)

  • Advice on how to understand in general and in practice IT Infrastructure

    - by Luca
    My IT knowledge resides mainly in SW development. I have just some basic know how about networks. On the net I tried to get information and read books in order to better understand the overall IT infrastrcuture, but all the sources I found are too generic or, mainly, too detailed in just one aspect, making me lost. Could anyone suggest some books or web resources as good compromise in details? My goal would be able to understand the network issues and security threats when, for example, two remote system have to be setup and put in connection each other. Considering this scenario there are several aspects to consider: firewalls, intranet/internet interconnections, certificates for httpS, etc. The argument is quite wide, therefore I was looking for something that might help to start to understand this subject without going too deep in details (Computer Networks from A.Tanenbaum is a wonderful milestone, but way too specific for my scope). Thanks

  • How to control fan speed and temperatures on Asus A8Js laptop?

    - by Azeworai
    I have tried installing asusfan and lm-sensors but I'm unable to control my fans to cool my laptop down sufficiently. Currently it overheats at about 100 degrees celsius and my sensors output somehow does not have any fan information on it: jackson@OLYMPIA:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +69.0°C (crit = +110.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +66.0°C (high = +100.0°C, crit = +100.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +66.0°C (high = +100.0°C, crit = +100.0°C) I have checked my bios and there isn't any fan settings there. I can consistently overheat just by converting a video via Handbrake. I have ubuntu-desktop installed for a GUI. Is there a way for me to control my fans to start spinning before it reaches a critical temperature and kills itself?

  • Unity: Assigning String value in inspector

    - by Marc Pilgaard
    I got an issue with Unity I can't seem to comprehend, and it is possibly very simple: I am trying to write a simple piece of code in JavaScript where a button toggles the activation of a shield, by dragging a prefab with Resources.load("ActivateShieldPreFab") and destroying it again (Haven't implemented that yet). I wish to assign this button through the inspector, so I have created a string variable which appears as intended in the inspector. Though it doesn't seem to register the inspector input, even though I changed the value through the inspector. It only provides the error: "Input Key named: is unknown" When the button name is assigned within the code, there is no issues. Code as follows: var ShieldOn = false; var stringbutton : String; function Start(){ } function Update () { if(Input.GetKey(stringbutton) && ShieldOn != true) { Instantiate(Resources.load("ActivateShieldPreFab"), Vector3 (0, 0, 0), Quaternion.identity); ShieldOn = true; } } Hope somebody can help, in advance... Thanks
