• Wake up from sleep with GPIO (I2C)

  - by spambas

  My situation: Ubuntu 10.10 running on an atom driven main board the main board has a GPIO chip integrated (F75111 by Fintek). They communicate through I2C(SMBus). We have a driver running that works, we can send outputs and read inputs. Great! We would like to use the I/O interface to suspend (sleep) and wake up again. Sleep is no problem. On an incoming input: run s2both. Ubuntu goes to sleep and prepares a hibernate state, so when the power-cord is unplugged by accident, it will wake from hibernate. But the big question: how to wake on an input if the OS is already sleeping! You can wake from a lot of devices (lan, usb, ring, etc) but I can't find out how to wake from a I2C card. PLEASE HELP!

• Wireless network unstable and often WPA2 protected networks just don't work

  - by Pedro

  I have an issue with my wireless network,so that the connection is working for only a few minutes, after which my browser no longer is able to load pages, even if the wireless is still active/connected. Furthermore, most of the time WPA2-personal protected networks don't work, (yesterday was the first time it worked - for a few minutes). By "don't work" I mean that it seems to successfully connect, but the browser can't load pages. I am running Ubuntu 10.10 32bit, and my wireless card is a RaLink rt3090. No changes have been done to any settings since Ubuntu was installed - networking began working on its own after the installation - but as described in first paragraph not very well.

• What are good JS libraries for game dev? (HTML5)

  - by acidzombie24

  If i decide to write a simple game both text and graphical (2d) what libs may i use? Assuming we are using a HTML5 compatible browser. The main things i can think of Rendering text on screen Animating sprites (using images/css) Input (capturing the arrow keys and getting relative mouse positions) Perhaps some preloading resource or dynamically loading resources and choosing order Sound (but i am unsure how important this will be to me at first). Perhaps with mixing and chaining sounds or looping forever until stop. Networking (low priority) to connect a user to another or to continuously GET data without multiple request (i know this exist but i dont know how easy it is to setup or use. But this isnt important to me. Its for the question).

• On-line Based Conferencing For Admin Panel

  - by Tim Marshall

  Working on my admin panels work station section which will allow the admin to use simple office tools such as word editors, calculators and whatnot. Under this section of the admin panel, I would like to add a conferencing feature which will allow any administrator to connect with another administrator 1-2-1 under the 1-2-1 Conferencing section, or to join a meeting under 'live meeting' section. Upon my search for on-line based, I found there are all these, what seem to be great applications out there, however not all of them are on-line based, and come with a price! I would like to a purely on-line based conferencing/meeting/1-2-1 feature which will allow administrators to communicate via text or sound, stream their video, share their screen and sending of files. I know this sounds like a big feature, and I am not asking for someone to answer by programming one for my website! Does anyone know my best solution to progress to having this feature on my website, any tutorials or free to use, free to modify web plugins? Thank you for your help, Best Regards, Tim

• Using paypal to process credit cards in Sweden through an API [on hold]

  - by Mastikator

  I'm looking for a Paypal API that lets me process credit cards to make payments without being redirected to a paypal site and without enforcing consumers to use their paypal account. And it needs to work in Sweden. The ones I've looked at (dodirectpayment, expresscheckout, paypalpro gateway) and none of them have let me process credit cards in Sweden via an API that doesn't force the user to visit the paypal login site. I have a form on my webpage that the user types their credit card number, ccv2, expiration, name, address, etc. I need an API that works in Sweden that simply processes the request, and it has to be without the step of being redirected into a paypal website. The ones that I have found only worked in a select few countries, is there an international solution? I've already spent over 12 work hours just looking for an API that meets my requirements.

• How do I install the driver for my Linksys AE1200 Wireless-N USB Adapter?

  - by Lewis Graham

  I recently downloaded Ubuntu from the main website with the hopes of dual booting it with Windows. While the operating system works, it says that I need to install a driver for my graphics card. When I type in my password the installation fails. I figure it is because I need Internet access. I tried to install my WiFi USB adapter with the installation disc but Ubuntu doesn't seem to run the setup when I click the exe. What are my available solutions as I would really like to use Ubuntu from my programming and Windows for my gaming needs? The name as read on the box is: Linksys AE1200 Wireless- N USB Adapter The description reads as such: ID 13b1:0039 Linksys (a comma messed up format) ID 046d:0a0b Logitech, Inc.

• Kubuntu 12.04 Won't let me search for wireless network

  - by Bora George

  Hello I'm running a brand new Kubuntu 12.04 single boot on my laptop, this is the first time I tried connecting to a wireless network. I tried using the network manager app allready on the task bar, but it doesn't let me tick the column to search for wireless networks, i.e. it will untick it automaticaly, it's dissabled by the software or the hardware, but I doubt it. I've tried searching the other questions on this site, and I can't see anything which helps with my problem. I know my wireless card is a Atheros AR9285, I don't think I installed any firmware for it, I'm sorry I can't offer more info but I'm completely new to networking and all that I have for the network to connect to are it's name and password of course.

• broadcom 43225 wireless on acer laptop is disabled

  - by Robbie

  I have a acer aspire 5820T with a broadcom 43225 wireless card. I previously used ubuntu 10.10 and the wireless worked straight away, but when I updated to 11.04 the wireless stopped working. I have managed to get the wireless hardware to switch on for a couple of seconds before turning off (When you turn the wireless on using the manual switch the wireless light stays on for a couple of seconds and in the drop down connections menu the information under wireless networks changes from 'device not ready' to 'Disconnected' but shows no wireless networks despite there being one). So far I have tried installing an additional driver, and also disabling the additional driver and installing b43-fwcutter and firmware b43 installer. There may have been other things that I've found in searches that i've tried but unfortunately I can't remember them. Any help would be appreciated.

• What is the ideal laptop for creative coding applications?

  - by Jason

  Hi, I am a creative coder using C++(cinder and OpenFrameworks) I am looking to upgrade from my MacBook, which slowed down to about 3fps this morning. My project involves particles systems and fluids reacting to audio analysis data and computer vision data in real-time. SD or HD? no biggie. I have asked many people what computer I need. Ideally, I want a MacBook Pro. But is that enough power? I've been told that I need a desktop for what I am doing though I'd rather stay portable I've been told that I should go PC linux to get the most power but I'd rather stay mac I've been told that RAM is more of bottleneck than processor speed I've been told that the Graphics Card is more important than CPU and that code optimizations such as using trees over lists, proper threading, sending tasks to the GPU make a bigger difference than the hardware!!! what's true?! what do I need? Any suggestions are greatly appreciated

• 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.

• 11.04 64 bit live install cd freezes immediately on boot

  - by wrchis

  I am trying to install 11.04 alpha to a free set of partitions to try it out but neither the regular graphic installer or the alternate installer work. The graphic one freezes when I try to boot the cd (or cd image on usb stick rather) with a distorted static picture of my regular desktop repeated four times. I have an nvidia 240 graphics card if that is any help in diagnosis. I think it is a matter of getting the cd image to use a low rez video mode but I have no idea how to force that. I have used both the iso's from the regular page and the daily page (for several days so far) and they all do the same thing. I have tried both the internal utility and unetbootin to set up the stick with the same results. The alternate installer seems to work up to the point of the software selection step and then throws a 'failed step' error part way through.

• Windows Store now open to lots more developers (120 markets!)

  - by Michael B. McLaughlin

  See the post here: http://blogs.msdn.com/b/windowsstore/archive/2012/09/11/windows-store-now-open-to-all-developers.aspx . This includes individual accounts now so if you tried signing up before and got a message about it only covering company accounts, you can sign up now. Don’t forget to verify your account and setup your payment and tax information. Also, if you are an MSDN subscriber you should be able to get a code from the MSDN site that will give you a free year (saving $49 US) but you will still need to submit some form of payment (e.g. credit or debit card) for verification purposes and so that they can automatically rebill you at the end of the subscription year (unless you’ve cancelled your account for some reason, of course). Go forth and register and make awesome games and apps for me to buy and play and use!

• nouveu driver logs into unity-2d by default

  - by Ubuntuser

  I have an old system with NVIDIA Corporation NV25 [GeForce4 Ti 4600]. When running Ubuntu , the nouveau driver loads fine but does not log into Unity with compiz. Instead it logs into Unity-2D. Any idea how to enable 3D/ compiz with the nouveau driver. OS: Ubuntu 12.04 Beta2 The nvidia driver is no more available for this graphics card, so have to rely on nouveau. UPDATE: Bug reported on launchpad . See here. There has been no reply as yet to this bug-report - does anyone have any idea how to resolve this? Further information, Also, if I use kubuntu desktop, kwin graphics works just fine. But, the users prefer Unity over KDE so I have uninstalled Kubuntu.

• Broadcom 4365 wireless driver on 12.04 with 3.4 / 3.5 kernel

  - by zaid

  I used this package to install the driver on 3.2 Kernel and it was working perfectly. Unfortunately the system used to freeze randomly with 3.2 kernel so I installed 3.4 kernel, now there is no freezing, the only problem is that my wifi card is not working, I tried to re-install the package, but didn't work. I can see the driver in the "additional drivers" and it say that it is active, but when I execute iwconfig it doesn't show up. I've even tried ndiswraper and that didn't work either. my lspci: 01:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01)

• Help me i can't format my usb? i have already tried with mkdosfs and gparted

  - by Mauri Olivares

  I have a MicroSD card in a USB adapter (which plugs into a USB port on my machine, and acts like a USB flash drive). I was using Unetbootin to make this a bootable USB flash drive with Kubuntu. But I needed to cancel while it was working. So I killed the Unetbootin process from the console. Since then, I can't format the MicroSD or delete the folder that Kubuntu made. I have also tried mkdosfs, with no success. I can't mount the drive anymore either? What can I do, to make this drive usable again? Trying to create a new partition table in GParted, as described in Eliah Kagan's answer, does not work. It fails with the error message "imposible crear tabla de particiones" ("unable to create a partition table").

• problem connecting to wifi at long range

  - by user171849

  I am using a compaq 8510p with internal wifi. The campground supplies an open wifi hotspot, to which I can connect at close range (30 ft) but not at longer range (300 ft). Connecting a usb dongle just confuses things. The dongle tries to lock on to all the wifi networks in my vicinity. They are password protected, but my laptop still tries to connect. I connected a cantenna via usb port and got a signal which said I was connected, but all web pages returned error 'unable to connect to server', despite having three bars showing on the wifi icon. I believe it because the installed wifi card interacts with the usb dongle. If so what can I do about it? I am using Ubuntu 12.04.

• HP 655 Notebook (Ubuntu 12.04) wireless internet disabled after running updates

  - by Bastian

  Today the update-manaeger suggested that I should download some updates. So I did. After the updates were installed I had to reboot the system. After the reboot my notebook doesn't see any wireless networks. I was looking for a long time on the internet for answers but non of them applies to my case. I have the idea, it has got something to do with the kernel I am currently using (Linux 3.2.0-55). Is this one new for Ubuntu 12.04? When I boot my system I can choose to use an older kernel (linux 3.2.0-32). When I use this one the notebook does see the wireless networks. This is my network card according to the command lspci: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe Anyone an idea to fix my problems with wireless internet?

• Ubuntu 12.04 nVidia TwinView tearing

  - by Andy Turfer

  I'm running Ubuntu 12.04. Today I just purchased a second monitor (I have a Dell U2711 and a 42-inch Sony TV). I'm running the 295.49 proprietary nVidia graphics driver, my graphics card is a GeForce GTX 460. I am not able to activate "xinerama" with "separate X screens", not sure why. I am able to use TwinView. This works, although it results in severe tearing on the Sony TV. It's as though "sync to vblank" isn't working (I have this set in Compiz and in the nVidia settings). If I disable the Dell U2711 and only use the Sony, everything works fine, zero tearing. Is it the case that "sync to vblank" can only work on a single monitor in Ubuntu 12.04? Is there any way to get rid of the tearing on the second monitor in TwinView mode?

• Looking for the better way to combine deep architecture refactoring with feature based development

  - by voroninp

  Problem statement: Given: TFS as Source Control Heavy desktop client application with tons of legacy code with bad or almost absent architecture design. Clients constantly requiring new features with sound quality, fast delivery and constantly complaining on user unfriendly UI. Problem: Application undoubtedly requires deep refactoring. This process inevitably makes application unstable and dedicated stabilization phase is needed. We've tried: Refactoring in master with periodical merges from master (MB) to feature branch (FB). (my mistake) Result: Many unstable branches. What we are advised: Create additional branch for refactoring (RB) periodically synchronizing it with MB via merge from MB to RB. After RB is stabilized we substitute master with RB and create new branch for further refactoring. This is the plan. But here I expect the real hell of merging MB to RB after merging any FB to MB. The main advantage: Stable master most of the time. Are there any better alternatives to the procees?
