• Detect orientation change, when only portrait is allowed on Android

  - by bicska88

  I have to solve the following: I have an Activity which's android:screenOrientation="portrait". Even though, when the device is rotated to landscape while this Activity is visible, I have to start another one, and, when the device is rotated back to portrait, I have to finish() the activity in landscape. I tried to perform this with a BroadcastReceiver, but this special activity doesn't receive any broadcasts because of the android:screenOrientation="portrait". Any help is well appreciated. Thanks.

• Is `std::string(strerror(errno))` dangerous?

  - by StackedCrooked

  At some places in my code, I print debug messages like this: int ret = getLinkSpeed(device.getSysName(), linkSpeed); if (ret < 0) { logDebug("Failed to obtain port speed for this device. Error: " + std::string(strerror(errno))); } From the documentation it is not entirely clear if strerror will return 0 under certain conditions (which would cause my code to crash). Does anyone know if it's safe?

• Iframe size manipulation

  - by portoalet

  Is there a way to make the Iframe request an external website as if it is a mobile device, so the content returned will have a small dimension etc? I am displaying external websites in iframes, using width and height attributes <iframe src="http://marketwatch.com" width="300px" height="300px" ></iframe> but because the browser is not a mobile browser, the content returned is tailored to normal browser, and I end up having scrollbars. If the content returned is that for a mobile device, then no more scrollbars etc.

• IE 11 Updates its Developers Tools

  - by Aligned

  Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/08/01/ie-11-updates-its-developers-tools.aspxI installed the IE 11 preview for Windows 7 (I’m getting upgraded to Windows 8 at work next week). I’ve never been a fan of the IE 8 – 10 developer tools so I’ve mostly been using Chrome or Firefox’s Firebug. This revamp looks great and seems to work well. I think I’ll be spending more time in IE with the developer tools, once IE 11 is released. “F12 Tools in Internet Explorer 11 Preview has been rebuilt from the ground up to give you: a new, cleaner user interface. new Responsiveness, Memory, and Emulation tools. new and improved functionality in familiar tools. an easier and faster workflow.” http://msdn.microsoft.com/en-us/library/ie/bg182632(v=vs.85).aspxhttp://ie.microsoft.com/testdrive/Browser/F12Adventure/ has a nice visual walk through of the new features.

• DIY Coffee Table Arcade Hides Retro Gaming Inside

  - by Jason Fitzpatrick

  Last week we showed you a nifty man-cave arcade-in-coffee-table build that was a bit, shall we say, exposed. If you’re looking for a sleek build that conceals its arcade-heart until it’s game time, this clean and concealed build is for you. Courtesy of IKEAHacker reader Sam Wang, the beauty of this build is that other than the rectangle of black glass in the center of the table–which could just as well be a design accent–there is no indication that the coffee table is a gaming machine when not in use. Slide out the drawers and boot it up, however, and you’re in business–full MAME arcade emulation at your finger tips. Hit up the link below to check out his full photo build guide.

• Where do I have to paste an "xinput" command so that it executes it when GNOME is started?

  - by michuk

  On my Thinkpad I need to execute something like this in the terminal: xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Middle Button Emulation" 8 1 so that my the 2 buttons on my touchpad emulate the middle mouse click. Now I need this line to be executed each time I start GNOMe or X or whatever, so that it "just works". I tried ~/.xsession or ~/.bashrc but to no avail. Should I put it in GNOME start scripts or in /etc/X somewhere? I'm using Ubuntu 11.10.

• Ubuntu on Mac mini and refit

  - by Thomas

  I have successfully installed Ubuntu pangolin 64 bit on a mac mini 2011 5,3 ( server version ). I have used the Ubuntu iso which I then converted to .dmg and dd'ed into an usb stick. I didn't want to keep OS X installed so I deleted the current partition and reformatted the drive as ext4 for / + a small swap partition. Everything seems to work nicely, but I have now a question since I read lots of reviews/howto when you people installed rEfit on Mac OS X. Did you use rEfit to be able to have a dual boot or there are other advantages by doing that ( apart that you will be able to download updated firmware for your hardware in the future via Mac OS ) like BIOS emulation and the like ?

• Did I lose my RAID again?

  - by BarsMonster

  Hi! A little history: 2 years ago I was really excited to find out that mdadm is so powerful that it even can reshape arrays, so you can start with a smaller array and then grow it as you need. I've bought 3x1Tb drives and made a RAID-5. It was fine for a year. Then I bought 2x more, and tried to reshape to RAID-6 out of 5 drives, and due to some mess with superblock versions, lost all content. Had to rebuild it from scratch, but 2Tb of data were gone. Yesterday I bought 2 more drives, and this time I had everything: properly built array, UPS. I've disabled write intent map, added 2 new drives as spares and run a command to grow array to 7-disks. It started working, but speed was ridiculously slow, ~100kb/sec. After processing first 37Mb at such an amazing speed, one of old HDDs fails. I properly shutdown the PC and disconnected the failed drive. After bootup it appeared that it recreated the intent map as it was still in mdadm config, so I removed it from config and rebooted again. Now all I see is that all mdadm processes deadlock, and don't do anything. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1937 root 20 0 12992 608 444 D 0 0.1 0:00.00 mdadm 2283 root 20 0 12992 852 704 D 0 0.1 0:00.01 mdadm 2287 root 20 0 0 0 0 D 0 0.0 0:00.01 md0_reshape 2288 root 18 -2 12992 820 676 D 0 0.1 0:00.01 mdadm And all I see in mdstat is: $ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid6 sdb1[1] sdg1[4] sdf1[7] sde1[6] sdd1[0] sdc1[5] 2929683456 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [7/6] [UU_UUUU] [>....................] reshape = 0.0% (37888/976561152) finish=567604147.2min speed=0K/sec I've already tried mdadm 2.6.7, 3.1.4 and 3.2 - nothing helps. Did I lose my data again? Any suggestions on how can I make this work? OS is Ubuntu Server 10.04.2. PS. Needless to say, the data is inaccessible - I cannot mount /dev/md0 to save the most valuable data.

• Compilable modern alternatives to C/C++

  - by Jeremy French

  I am considering writing a new software product. Performance will be critical, so I am wary of using an interpreted or language or one that uses a emulation layer (read java). Which leads me to thinking of using C (or C++) however these are both rather long in the tooth. I haven't used either for a long time. I figure in the last 20 years someone should have created something which is reasonably popular and is nice to code in and is complied. What more modern alternatives are there to C for writing high performance code compiled code? edit in response to comments If C++ is a different beast than it was 15 years ago, I would consider it, I guess I had an assumption that it had some inherent problems. Parallelisation would be important, but probably not across multiple machines.

• A Virtual(Box) Christmas!

  - by Gilles Gravier

  Hello and merry Christmas everybody!Yes. This year, it's a v4.0 Xmas! VirtualBox just came out with a new major version release. Version 4.0 is available at : http://www.virtualbox.org/wiki/Downloads ... and of course, it's open source, and it's free. And I suggest (strongly) that you also download the free Extension Pack from the same page... Brings USB 2.0 emulation and more!I upgraded the version on my Solaris Express (get that from : http://www.oracle.com/solaris/index.html and follow the Download Solaris Express link on the right) laptop (pfexec pkgrm SUNWvbox and then pfexec pkgadd -d the .pkg in the compressed archive file, and install the extensions from the VBox GUI once it's launched). If you are on an old fashion OS without proper RBAC, replace pfexec by sudo. Which you can also do on Solaris if you really want to. :)I tell you, it's Christmas, for sure!Merry VBox!Gilles.

When I ssh to it using PuTTY (on a Windows machine), I find it responds to Ctrl+S and Ctrl+Q as XON/XOFF transmission control (i.e. the terminal freezes everytime I type Ctrl+S until I type Ctrl + Q). This hasn't been a problem on other remote servers, and I realise I don't really have much idea about how this is determined. Is this something that is negotiated at the start of the terminal session, something that is set by the choice of terminal emulation (TERM=xterm, if that helps) or - as I suspect - some setting on the server I am not aware of. How do I tell Ubuntu that it is 2011, and no-one has terminals that rely on XON/XOFF any more?

• How to run Java application in KDE with Qt-like UI?

  - by squallbayu

  Continuing my question in Install Ubuntu or Kubuntu? I have tried Kubuntu (KDE), and it was very cool as cool as Ubuntu (GNOME). but there is little problem with its user interface when we start Java application (LimeWire, Netbeans, Eclipse). User interface changed to Metal, (which I think is a bit old school). Can we run it with Qt like UI?, such as when we start Java application in Gnome (run with GTK like UI/emulation GTK like UI)? I hear there is a class for Java in order to make Java application UI like Qt, called the Qt/Jambi bindings for Java. How can we integrate it in KDE when we start Java application? My other question is if not wrong, OpenOffice was built in Java,so why OpenOffice can run with Qt like UI in KDE?

• Mouse wheel on Dell Vostro V13

  - by Scaine

  I have a Dell Vostro V13, which Canonical claim is "Certified" for Ubuntu (http://www.ubuntu.com/certification/make/Dell/laptops). So it surprises me that the synaptics trackpad isn't recognised as such and defaults to psmouse emulation. This means no multitouch, no gestures, and more importantly, no mousewheel scrolling. Because it's not loading the synaptic driver, running gpointing-device-settings doesn't help. I've found this bug : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/380126 which suggests a fix has been committed, but I can't see a way of getting this loaded on my Maverick build. I've tried backports and proposed repos in synaptic, but no joy. Any ideas?
