  • Bluetooth device won't re-add after being removed (Windows 7)

    - by HericDenis
    I've got a SBH52 headset, it works fine on my android phone, then I tried to use it with my Windows 7 PC, then it won't work because Microsoft Windows dosen't have native support for A2DP connections and one of the answers on the previous link said that removing the device from "devices and printers", running this software and then re-add the device would solve the problem. But the big problem is that they won't pair again: I tried, hopelessly, the suggested fixes from Windows, it won't work. By the way, it is Windows 7 (x64), it just looks like Windows 8. I had this problem once many years ago with other PC and Bluetooth device, I remember it had something to do with drivers that were not removed and I tried to delete them from somewhere, and as far as I remember it worked, but no idea how. In short, how can I pair it again with my PC?

  • Android market going down the drain?

    <b>Ian's Thoughts:</b> "You can search the Android Market for the following keywords and see quite a bit of content that I feel shouldn't be available to customers, and definitely not to children: nude, sex, porn, 18+, adults only, boobs, the android market seems to be turning into a porn hub."

  • moving to a new dedicated server and need advice on the new setup

    - by Eric Martin
    I currently have a dedicated server that we have outgrown and we are moving to another server. Our current setup was a 8gb W2008R2 server running a W2008R2 IIS virtual machine using VMWare. We are moving to a 2 cpu 24 gb server with W2012 R2 on Hyper-V. On our virtual machine we are running iis 7.5 and sql server. Sql Server seems to want to eat up all the memory so I had to cap it at 2gb, which doesn't seem sufficient. My question is, when I move the virtual machine to the new server, should I create 2 virtual machines, one for sql server and one for IIS? Or should I leave them both on the same virtual machine? Or even, put the Sql Server on the dedicated server and run the IIS in the vm? I'd like some input on how this should be done, I've not got the experience needed to make the right call. Thanks!

  • Recommended workflows for Apache virtual hosts?

    - by craig zheng
    I do a lot of local web development work on my Ubuntu machine, and I'm constantly setting up virtual hosts in Apache. I don't need to do hard core server management, but I am getting tired of the repetitive process of manually adding config directives to files in /etc/apache2/sites-available/ and then updating the /etc/hosts file. Is there a more efficient or more automated way to do all this that I'm missing? Maybe something like rapache but that's actually working?

  • Reasons to Use a VM For Development

    - by George Stocker
    Background: I work at a start-up company, where one team uses Virtual Machines to connect to a remote server to do their development, and another team (the team I'm on) uses local IIS/SQL Server 2005/Visual Studio installations to conduct work. Team VM is located about 1000 miles from Team Non-VM, and the servers the VMs run off of are located near Team VM (Latency, for those that are wondering, is about 50ms). A person high in the company is pushing for Team Non-VM to use virtual machines for programming, development, and testing. The latter point we agree on -- we want Virtual Machines to test configurations and various aspects of the web application in a 'clean' state. The Problem: What we don't agree on is having developers using RDP to connect to a desktop remotely that contains Visual Studio, SQL Server, and IIS to do the same development we could do locally on our laptops. I've tried the VM set-up, and besides the color issue, there is a latency issue that is rather noticeable, not to mention that since we're a start-up, a good number of employees work from home on occasion with our work laptops, and this move would cut off the laptops. They'd be turned in. Reasons to Use Remote VMs for Development (Not Testing!): Here are the stated reasons that this person wants us to use VMs: They work for TeamVM. They keep the source code "safe". If we want to work from home, we could just use our home PCs. Licenses (I don't know what the argument is, only that it's been used). Reasons not to use Remote VMs for Development: Here are the stated reasons why we don't want to use VMs: We like working from home. We get a lot done on our own time. We're not going to use our Home PCs to do work related stuff. The Latency is noticeable. Support for the VMs (if they go down, or if we need a new VM) takes a while. We don't have administrative privileges on the VM, and are unable to change settings as needed. What I'm looking for from the community is this: What reasons would you give for not using VMs for development? Keep in mind these are remote VMs -- this isn't a VM running on a local desktop. It's using the laptop (or a desktop) as a thin client for a remote VM. Also, on the other side of the coin: Is there something we're missing that makes VMs more palatable for development? Edit: I think 'safe' is used in term of corporate espionage, or more correctly if the Laptop gets stolen, the person who stole would have access to our source code. The former (as we've pointed out, is always going to be a possibility -- companies stop that with litigation, there isn't a technical solution (so far as I can see)). The latter point is ( though I don't know its usefulness in a corporate scenario) mitigated by Truecrypt'ing the entire volume.

  • Why is my Internet connection randomly dropping?

    - by Jeanno
    Ever since I have installed 12.04 (clean install not an upgrade), i have been having a drop in the Internet connection. The drop in the connection can be anything from 15 seconds to about 3 mins, and then the connection comes back. This behaviour happens while I am actively browsing the Internet, or if I wake up the computer and open Firefox (sometimes I have connection and sometimes I don't) . Please note that when the internet connection is on, it is not slow (as speedtest.net results show) In the beginning, I thought it was a problem with the driver r8169 for my RTL8111/8168B Ethernet card, so I downloaded the r8168 from Realtek website, followed the detailed instructions (blacklisted r8169, changed the file to '.bsh' ...), but still the same problem persisted. So I switched to a wireless connection, and I got the same problem with internet connection dropping randomly. Any ideas?

  • User Experience Guidance for Developers: Anti-Patterns

    - by ultan o'broin
    Picked this up from a recent Dublin Google Technology User Group meeting: Android App Mistakes: Avoiding the Anti-Patterns by Mark Murphy, CommonsWare Interesting approach of "anti-patterns" aimed at mobile developers (in this case Android), looking at the best way to use code and what's in the SDK while combining it with UX guidance (the premise being the developer does the lot). Interestingly, the idea came through that developers need to stop trying to make one O/S behave like another--on UX grounds. Also, pretty clear that a web-based paradigm is being promoting for Android (translators tell me that translating an Android app reminded them of translating web pages too). Haven't see the "anti"-approach before, developer cookbooks and design patterns sure. Check out the slideshare presentation.

  • Oracle ADF Mobile and Developing On-device Mobile Applications

    - by Joe Huang
    Hi, everyone: It has been almost a year since we posted to this blog, and I am happy to report that we are steadily marching toward releasing a new generation of ADF Mobile.  This blog site has been quiet as we are heads down to develop this new generation of ADF Mobile.  As we are nearing releasing this next generation product, there are substantial number of Oracle internal application teams and external customers/partners actively developing using the beta version of this framework.  We are actively taking feedbacks from these teams and ensuring the product is ready for general availability. If you are intersted for more details around this new generation of ADF Mobile, we are hosting a session and a hands on lab this week at the ODTUG KScope 12 conference.  The lab is booked completely full weeks in advance, but perhaps you can still get into the session (Wed at 9:45 AM).   Look for updates from this blog site as well as the Oracle OTN ADF Mobile landing page during the weeks leading to Oracle OpenWorld 2012.   Thanks, Joe Huang

  • Cheap programmable, portable device

    - by Ars
    Since a long time I have thrived for being able to program something I can take with me - a very small computer like a programmable calculator, gameboy, pocket PC or cellphone. However, I didn't find anything fitting yet! The thing I'm looking at is the price, because I can't afford to spend too much money on it. What are some cheap portable programmable devices? All I'd need is support for uploading assembler code from my computer. I don't care about the display, a simple LCD would be sufficient. Same goes for the buttons I have looked at programmable calculators, portable gaming consoles such as the PSP and more, however didn't find anything that fit :(

  • Xperia handset - cannot send files using bluetooth

    - by Sandeepan Nath
    My friend has a Sony Ericsson Xperia (most probably X8) handset which is an Android based smartphone. He is not able to send files through bluetooth but able to receive. I don't exactly remember the version of Android which he is currently having. He has tried to download and install the required update using the same phone (he has internet connected) from http://www.sonyericsson.com but not able to install it. So, he asked me to help him. Which version of Android do you think he has? Does it seem like he does not have Android 2.1 installed. It is written here (click on Xperia X8) that If your phone already has Android 2.1, you can use your mobile network* or a WiFi connection to download the software. Is it possible that he does not have updated Android and so not able to download? If so, does he need to upgrade to Android 2.1 first? Should it be done by connecting it to a PC?

  • HTC Trophy not detected

    - by Earl Larson
    When I plug in the device via USB chord, nothing happens and the device is not shown on the desktop. However, when I type "lsusb" into a terminal this is the output: Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 002: ID 04f2:b249 Chicony Electronics Co., Ltd Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 005: ID 045e:04ec Microsoft Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub I'm assuming Microsoft Corp. is the device but why isn't Ubuntu displaying it on the desktop?

  • Xen DomU on DRBD device: barrier errors

    - by Halfgaar
    I'm testing setting up a Xen DomU with a DRBD storage for easy failover. Most of the time, immediatly after booting the DomU, I get an IO error: [ 3.153370] EXT3-fs (xvda2): using internal journal [ 3.277115] ip_tables: (C) 2000-2006 Netfilter Core Team [ 3.336014] nf_conntrack version 0.5.0 (3899 buckets, 15596 max) [ 3.515604] init: failsafe main process (397) killed by TERM signal [ 3.801589] blkfront: barrier: write xvda2 op failed [ 3.801597] blkfront: xvda2: barrier or flush: disabled [ 3.801611] end_request: I/O error, dev xvda2, sector 52171168 [ 3.801630] end_request: I/O error, dev xvda2, sector 52171168 [ 3.801642] Buffer I/O error on device xvda2, logical block 6521396 [ 3.801652] lost page write due to I/O error on xvda2 [ 3.801755] Aborting journal on device xvda2. [ 3.804415] EXT3-fs (xvda2): error: ext3_journal_start_sb: Detected aborted journal [ 3.804434] EXT3-fs (xvda2): error: remounting filesystem read-only [ 3.814754] journal commit I/O error [ 6.973831] init: udev-fallback-graphics main process (538) terminated with status 1 [ 6.992267] init: plymouth-splash main process (546) terminated with status 1 The manpage of drbdsetup says that LVM (which I use) doesn't support barriers (better known as tagged command queuing or native command queing), so I configured the drbd device not to use barriers. This can be seen in /proc/drbd (by "wo:f, meaning flush, the next method drbd chooses after barrier): 3: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r---- ns:2160152 nr:520204 dw:2680344 dr:2678107 al:3549 bm:9183 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 And on the other host: 3: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r---- ns:0 nr:2160152 dw:2160152 dr:0 al:0 bm:8052 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 I also enabled the option disable_sendpage, as per the drbd docs: cat /sys/module/drbd/parameters/disable_sendpage Y I also tried adding barriers=0 to fstab as mount option. Still it sometimes says: [ 58.603896] blkfront: barrier: write xvda2 op failed [ 58.603903] blkfront: xvda2: barrier or flush: disabled I don't even know if ext3 has a nobarrier option. And, because only one of my storage systems is battery backed, it would not be smart anyway. Why does it still compain about barriers when I disabled that? Both host are: Debian: 6.0.4 uname -a: Linux 2.6.32-5-xen-amd64 drbd: 8.3.7 Xen: 4.0.1 Guest: Ubuntu 12.04 LTS uname -a: Linux 3.2.0-24-generic pvops drbd resource: resource drbdvm { meta-disk internal; device /dev/drbd3; startup { # The timeout value when the last known state of the other side was available. 0 means infinite. wfc-timeout 0; # Timeout value when the last known state was disconnected. 0 means infinite. degr-wfc-timeout 180; } syncer { # This is recommended only for low-bandwidth lines, to only send those # blocks which really have changed. #csums-alg md5; # Set to about half your net speed rate 60M; # It seems that this option moved to the 'net' section in drbd 8.4.

Detach is not default for historical reasons, but is # recommended by the docs. # However, the Debian defaults in drbd.conf suggest the machine will reboot in that event... on-io-error detach; # LVM doesn't support barriers, so disabling it. It will revert to flush. Check wo: in /proc/drbd. If you don't disable it, you get IO errors. no-disk-barrier; } on host1 { # universe is a VG disk /dev/universe/drbdvm-disk; address 10.0.0.1:7792; } on host2 { # universe is a VG disk /dev/universe/drbdvm-disk; address 10.0.0.2:7792; } } DomU cfg: bootloader = '/usr/lib/xen-default/bin/pygrub' vcpus = '2' memory = '512' # # Disk device(s). # root = '/dev/xvda2 ro' disk = [ 'phy:/dev/drbd3,xvda2,w', 'phy:/dev/universe/drbdvm-swap,xvda1,w', ] # # Hostname # name = 'drbdvm' # # Networking # # fake IP for posting vif = [ 'ip=1.2.3.4,mac=00:16:3E:22:A8:A7' ] # # Behaviour # on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' In my test setup: the primary host's storage is 9650SE SATA-II RAID PCIe with battery. The secondary is software RAID1. Isn't DRBD+Xen widely used? With these problems, it's not going to work.
