• Can't get TRIM test to work

  - by Matthew Marcus

  So I'm attempting to install TRIM using the walkthrough here: How to enable TRIM? But everytime I attempt to run the hdparm command, I get the following when I try to run it w/ sda: reading sector 5805056: FAILED: Input/output error and I get this when running it with sda1: /dev/sda1: Device /dev/sda1 has non-zero LBA starting offset of 2048. Please use an absolute LBA with the /dev/ entry for the full device, rather than a partition name. /dev/sda1 is probably a partition of /dev/sda (?) The absolute LBA of sector 5807104 from /dev/sda1 should be 5809152 Aborting. I'm running Natty in a VBox on Windows 7. Someone PLEASE help.. I keep getting this "consistency check" message on boot of my machine and I think it's because Ubuntu is writing to the same sectors on the VHD too much.. need to get trim working on this thing.. Thanks.

• Application for taking pretty screenshots (like OS X does)

  - by Oli

  I've been building a website for a guy who uses Mac OS X and occasionally he sends me screenshots of bugs. They come out looking like this: This is fairly typical of Mac screenshots. You get the window decorations, the shadow from the window and a white or transparent background (not the desktop wallpaper -- I've checked). Compare this to an Ubuntu window-shot (Alt+Print screen): It's impossible to keep a straight face and say the Ubuntu one anywhere near as elegant. My question is: Is there an application that can do this in Ubuntu? Edit: Follow up: Is there an application that can do this in one move? Shutter is pretty good but running the plugin for every screenshot is pretty tiresome as it doesn't seem to remember my preference (I want south-shadow and that requires selecting south, then clicking refresh, then save) and it's more clicks than I'd like. Is there a simple way of telling shutter I want south-shadow for all screenshots (except entire desktop and area-selection)?

  When I execute the updater it always throws the same error saying: Failed to download repository information. Check your internet connection. And when I run the sudo apt-get update I get these lines at the end: W: Failed to fetch cdrom://Ubuntu 13.10 Saucy Salamander - Release i386 (20131016.1)/dists/saucy/main/binary-i386/Packages Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs W: Failed to fetch cdrom://Ubuntu 13.10 Saucy Salamander - Release i386 (20131016.1)/dists/saucy/restricted/binary-i386/Packages Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs W: Failed to fetch http://ppa.launchpad.net/tiheum/equinox/ubuntu/dists/saucy/main/source/Sources 404 Not Found W: Failed to fetch http://ppa.launchpad.net/tiheum/equinox/ubuntu/dists/saucy/main/binary-i386/Packages 404 Not Found E: Some index files failed to download.

• Two 12.04 machines have the same display settings but different results

  - by durron597

  I have one machine that has a relatively fresh install of 12.04 and one that I inherited. The terminal window in the inherited machine has a really weird font, and the regular one is what I would expect. Especially the behavior of the "m" character is messed up. Note: both of these machines are on the same KVM switch. Here is what I've tried: MyUnity on both machines seem the same .bashrc on both machines seem similar in all the ways that would matter for this issue The terminal profiles on both machines are the default Here are the xrandr outputs: Good xrandr: Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 4096 x 4096 VGA1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm 1280x1024 60.0 + 76.0 75.0* 72.0 70.0 1152x864 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 640x480 72.8 75.0 66.7 60.0 720x400 70.1 Bad xrandr: Screen 0: minimum 8 x 8, current 1280 x 1024, maximum 8192 x 8192 DP-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DP-3 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm 1280x1024 60.0*+ 76.0 75.0 72.0 70.0 1152x864 75.0 1024x768 75.0 70.1 60.0 800x600 75.0 72.2 60.3 640x480 75.0 72.8 59.9 Finally here are screenshots of both machines, it seems to really only be Terminal, I have askubuntu behind the terminal window for comparison: Good screenshot: Bad Screenshot: Any thoughts as to what this might be?

• How does ecryptfs impact harddisk performance?

  - by Freddi

  I have my home directy encrypted with ecryptfs. Does ecryptfs lead to fragmentation? I have the feeling that reading files, displaying folders and login became continuously slower and slower (although it was not noticeably slow at the beginning). The hard disk makes a lot of seek noise even if I open only a text file. In /home/.ecryptfs I see many big archives (that probably contain the encrypted files), so I'm wondering if Linux file system online defragmentation gains anything here. What options do I have to increase performance? Should I decide whether I maybe better do without encryption?

• HTG Explains: Do Non-Windows Platforms Like Mac, Android, iOS, and Linux Get Viruses?

  - by Chris Hoffman

  Viruses and other types of malware seem largely confined to Windows in the real world. Even on a Windows 8 PC, you can still get infected with malware. But how vulnerable are other operating systems to malware? When we say “viruses,” we’re actually talking about malware in general. There’s more to malware than just viruses, although the word virus is often used to talk about malware in general. Why Are All the Viruses For Windows? Not all of the malware out there is for Windows, but most of it is. We’ve tried to cover why Windows has the most viruses in the past. Windows’ popularity is definitely a big factor, but there are other reasons, too. Historically, Windows was never designed for security in the way that UNIX-like platforms were — and every popular operating system that’s not Windows is based on UNIX. Windows also has a culture of installing software by searching the web and downloading it from websites, whereas other platforms have app stores and Linux has centralized software installation from a secure source in the form of its package managers. Do Macs Get Viruses? The vast majority of malware is designed for Windows systems and Macs don’t get Windows malware. While Mac malware is much more rare, Macs are definitely not immune to malware. They can be infected by malware written specifically for Macs, and such malware does exist. At one point, over 650,000 Macs were infected with the Flashback Trojan. [Source] It infected Macs through the Java browser plugin, which is a security nightmare on every platform. Macs no longer include Java by default. Apple also has locked down Macs in other ways. Three things in particular help: Mac App Store: Rather than getting desktop programs from the web and possibly downloading malware, as inexperienced users might on Windows, they can get their applications from a secure place. It’s similar to a smartphone app store or even a Linux package manager. Gatekeeper: Current releases of Mac OS X use Gatekeeper, which only allows programs to run if they’re signed by an approved developer or if they’re from the Mac App Store. This can be disabled by geeks who need to run unsigned software, but it acts as additional protection for typical users. XProtect: Macs also have a built-in technology known as XProtect, or File Quarantine. This feature acts as a blacklist, preventing known-malicious programs from running. It functions similarly to Windows antivirus programs, but works in the background and checks applications you download. Mac malware isn’t coming out nearly as quick as Windows malware, so it’s easier for Apple to keep up. Macs are certainly not immune to all malware, and someone going out of their way to download pirated applications and disable security features may find themselves infected. But Macs are much less at risk of malware in the real world. Android is Vulnerable to Malware, Right? Android malware does exist and companies that produce Android security software would love to sell you their Android antivirus apps. But that isn’t the full picture. By default, Android devices are configured to only install apps from Google Play. They also benefit from antimalware scanning — Google Play itself scans apps for malware. You could disable this protection and go outside Google Play, getting apps from elsewhere (“sideloading”). Google will still help you if you do this, asking if you want to scan your sideloaded apps for malware when you try to install them. In China, where many, many Android devices are in use, there is no Google Play Store. Chinese Android users don’t benefit from Google’s antimalware scanning and have to get their apps from third-party app stores, which may contain infected copies of apps. The majority of Android malware comes from outside Google Play. The scary malware statistics you see primarily include users who get apps from outside Google Play, whether it’s pirating infected apps or acquiring them from untrustworthy app stores. As long as you get your apps from Google Play — or even another secure source, like the Amazon App Store — your Android phone or tablet should be secure. What About iPads and iPhones? Apple’s iOS operating system, used on its iPads, iPhones, and iPod Touches, is more locked down than even Macs and Android devices. iPad and iPhone users are forced to get their apps from Apple’s App Store. Apple is more demanding of developers than Google is — while anyone can upload an app to Google Play and have it available instantly while Google does some automated scanning, getting an app onto Apple’s App Store involves a manual review of that app by an Apple employee. The locked-down environment makes it much more difficult for malware to exist. Even if a malicious application could be installed, it wouldn’t be able to monitor what you typed into your browser and capture your online-banking information without exploiting a deeper system vulnerability. Of course, iOS devices aren’t perfect either. Researchers have proven it’s possible to create malicious apps and sneak them past the app store review process. [Source] However, if a malicious app was discovered, Apple could pull it from the store and immediately uninstall it from all devices. Google and Microsoft have this same ability with Android’s Google Play and Windows Store for new Windows 8-style apps. Does Linux Get Viruses? Malware authors don’t tend to target Linux desktops, as so few average users use them. Linux desktop users are more likely to be geeks that won’t fall for obvious tricks. As with Macs, Linux users get most of their programs from a single place — the package manager — rather than downloading them from websites. Linux also can’t run Windows software natively, so Windows viruses just can’t run. Linux desktop malware is extremely rare, but it does exist. The recent “Hand of Thief” Trojan supports a variety of Linux distributions and desktop environments, running in the background and stealing online banking information. It doesn’t have a good way if infecting Linux systems, though — you’d have to download it from a website or receive it as an email attachment and run the Trojan. [Source] This just confirms how important it is to only run trusted software on any platform, even supposedly secure ones. What About Chromebooks? Chromebooks are locked down laptops that only run the Chrome web browser and some bits around it. We’re not really aware of any form of Chrome OS malware. A Chromebook’s sandbox helps protect it against malware, but it also helps that Chromebooks aren’t very common yet. It would still be possible to infect a Chromebook, if only by tricking a user into installing a malicious browser extension from outside the Chrome web store. The malicious browser extension could run in the background, steal your passwords and online banking credentials, and send it over the web. Such malware could even run on Windows, Mac, and Linux versions of Chrome, but it would appear in the Extensions list, would require the appropriate permissions, and you’d have to agree to install it manually. And Windows RT? Microsoft’s Windows RT only runs desktop programs written by Microsoft. Users can only install “Windows 8-style apps” from the Windows Store. This means that Windows RT devices are as locked down as an iPad — an attacker would have to get a malicious app into the store and trick users into installing it or possibly find a security vulnerability that allowed them to bypass the protection. Malware is definitely at its worst on Windows. This would probably be true even if Windows had a shining security record and a history of being as secure as other operating systems, but you can definitely avoid a lot of malware just by not using Windows. Of course, no platform is a perfect malware-free environment. You should exercise some basic precautions everywhere. Even if malware was eliminated, we’d have to deal with social-engineering attacks like phishing emails asking for credit card numbers. Image Credit: stuartpilbrow on Flickr, Kansir on Flickr

• Ubuntu 14.04: After login, top- and sidepanel don't load and system settings don't open

  - by Löwe Simon

  I have Ubuntu 14.04 on a Medion Erazer with the Nvidia GTX570M card. At first, while I had not installed the last nvidia driver, each time I would try to suspend my pc it would freeze frame on the login. Once I managed to install the nvidia drivers, everything seemed to work up until I noticed that suddenly the system settings would not open anymore. I then rebooted my pc, but when I logged in I just end up with my cursor but no top panel or side pannel. Thankfully, I had installed the gnome desktops which works, except for the fact the system settings do not open also in the gnome desktop. I have tried following: Problems after upgrading to 14.04 (only background and pointer after login) except for reinstalling nvidia, since then I would be back at square one with suspend not working. When I try to launch system settings through the terminal, I get: simon@simon-X681X:~$ unity-control-center libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast (unity-control-center:2806): Gdk-ERROR **: The program 'unity-control-center' received an X Window System error. This probably reflects a bug in the program. The error was 'BadLength (poly request too large or internal Xlib length erro'. (Details: serial 229 error_code 16 request_code 155 (GLX) minor_code 1) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Trace/breakpoint trap (core dumped) I know the 2 problems seem unrelated, but since they occured together, I am wondering if that is really the case. Your help is much appreciated, Simon

• What do the 4 keyboard input method systems in 10.04 mean?

  - by Android Eve

  I am trying to install another language support (in addition to the default US). Checking that language checkbox in "Install / Remove Languages..." wasn't too difficult. :) But now I want to add keyboard support, too, for that language. Again, I am prompted with a nice listbox with the following 4 options: none ibus lo-gtk th-gtk But I have no idea what these mean. I googled "ubuntu 10.04 keyboard input method system none ibus lo-gtk th-gtk" but all I could find was descriptions of problems, not an actual definition. Could you please point me to a webpage where I can learn about the meanings of these 4 different methods and +'s and -'s of each?

• How do I recover a BTRFS filesystem with "parent transid verify failed" errors?

  - by Evan P.

  I've got an external USB disk running btrfs. I use it for backups, and each time I do a backup I take a snapshot. However, it's giving me this error now: parent transid verify failed on 109973766144 wanted 1823 found 1821 parent transid verify failed on 109973766144 wanted 1823 found 1821 Obviously, this is a non-critical disk, but I have a few files on here that aren't available elsewhere. Is there any way to recover data from this disk? Maybe by mounting one of the snapshots as root?

It would eventually start working after I messed around with the audio settings, but it happened every restart. I eventually switched to SMPlayer, but now I need some of the features that VLC offers, but I still can't use VLC. At this point, the audio can not be heard at all, and the method I used before, messing around with the audio settings, isn't getting me anywhere. (note, I reposted this on VideoLan's forums, link is here: http://forum.videolan.org/viewtopic.php?f=13&t=104726) Please let me know if you need more information, or are confused by something I posted!

• Math-font from the ubuntu font family?

  - by Wauzl

  Does anyone know if there will be (or already are) any possibilities to use the ubuntu font family for mathematical typesetting in LaTeX? It says “Dalton Maag, a London-based studio, has laid the foundations for the Ubuntu font project with a beautiful design that aims to produce every character to support every language and interest in the world.” on the project web site of ubuntu. So I would expect something like this because maths is an interest.

• How do I pin a particular MySQL version to avoid unnecessary upgrades?

  - by asparagino

  I'm running a MySQL server, and want to keep it up to date with regular apt-upgrades. I don't want this to cause MySQL to upgrade unless I'm doing it during scheduled downtime! How do I alter my apt-preferences so that this won't happen? I've tried adding this to a file as /etc/apt/preferences.d/pin-mysql Package: mysql-client-5.1 Pin: version 5.1.41-3ubuntu12.7 Pin-Priority: 1001 Package: mysql-client-core-5.1 Pin: version 5.1.41-3ubuntu12.7 Pin-Priority: 1001 Package: mysql-common Pin: version 5.1.41-3ubuntu12.7 Pin-Priority: 1001 Package: mysql-server Pin: version 5.1.41-3ubuntu12.7 Pin-Priority: 1001 Package: mysql-server-5.1 Pin: version 5.1.41-3ubuntu12.7 Pin-Priority: 1001 Package: mysql-server-core-5.1 Pin: version 5.1.41-3ubuntu12.7 Pin-Priority: 1001 That then states the packages are pinned with "apt-cache policy" outputting: ... all package sources here 500 http://security.ubuntu.com/ubuntu/ lucid-security/universe Packages release v=10.04,o=Ubuntu,a=lucid-security,n=lucid,l=Ubuntu,c=universe origin security.ubuntu.com 500 http://security.ubuntu.com/ubuntu/ lucid-security/restricted Packages release v=10.04,o=Ubuntu,a=lucid-security,n=lucid,l=Ubuntu,c=restricted origin security.ubuntu.com ... etc Pinned packages: mysql-server -> 5.1.41-3ubuntu12.7 mysql-server-core-5.1 -> 5.1.41-3ubuntu12.7 mysql-client-core-5.1 -> 5.1.41-3ubuntu12.7 mysql-common -> 5.1.41-3ubuntu12.7 mysql-server-5.1 -> 5.1.41-3ubuntu12.7 mysql-client-5.1 -> 5.1.41-3ubuntu12.7 However... running aptitude safe-upgrade just updated MySQL... what am I doing wrong?

• How to Use Offline Files in Windows to Cache Your Networked Files Offline

  - by Taylor Gibb

  The problem with storing all your files on a file server or networked machine is that when you leave the network, how are you going to access your files? Instead of using a VPN or Dropbox, you can use the Offline Files feature built into Windows. Note: You should probably not be using this guide to make your 2 terabyte movie collection available offline—while it may work, it is not recommended just because the Offline Files feature isn’t made for storing massive amounts of data offline.

• How to reenable Documents on iPhone?

  - by Matt

  So, I regularly plug in my iPhone to my computer to get voice recordings off of it. However, every time I plugged it in "iPhone" and "Documents on iPhone" would both mount, and "Documents on iPhone" would pop up automatically. As I normally don't need anything on there it was a bit of a nuisance, so I opened a terminal and ran: sudo apt-get install libimobiledevice-utils;idevicepair unpair && idevicepair pair as suggested a here This, however, took away my access to "Documents on iPhone" completely, and didn't provide an alternative like putting it in a folder on the main "iPhone" device. Now I actually NEED to get something off there. Is there anyway to get "Documents on iPhone" back? I would prefer it still didn't pop up automatically but that's a sacrifice I'm willing to make. UPDATE: I ran idevicepair pair and unplugged and replugged my phone. I now have Documents back but it still annoyingly opens every time I plug in.

The scan reported a vulnerability in apache 2.2.22 (Apache HTTP Server Zero-Length Directory Name in LD_LIBRARY_PATH Vulnerability).The report states to upgrade the version to the latest stable release of either 2.2.23 or 2.2.24. How do I upgrade to the 2.2.23 to fix the vulnerability or is there a patch available that can fix this and if yes can you let me know how that can be patched.

• No USB 04b4:0307 mike input after 10.04

  - by Papou

  I am using an USB phone that is in fact a so-called "sound card" based on the 04b4:0307 chip. In fact, I have two different phones using 04b4:0307 and in fact I have a sound USB key too. This, I believe, is the start of why they call 04b4:0307 "ubiquitous" (instead of oh four bee...). But not "eternal". The mike worked in Ubuntu 9.10 and 10.04 but not later ([email protected]). "not working" means that 04b4:0307 shows in Sound Preference but that its vu-meter is mute. I have posted the full lsusb and the result of tests in various systems here: http://www.papou.byethost9.com/tmp/1043601.html Note: Tests done on VirtualBox (thankfully). But UbuntUnity no longer works on VB, so I used the LinuxMint equivalent. ?hat's fate. I could not find any problem report close enough. What should be my next step? I believe the problem occurs in module snd-usb-audio. One thing I might try if I knew how is hacking a DEB with its 10.04's source. I can hack DEBs. Any hint welcome on how to make a DEB overriding a kernel packed module. I mean that the newly installed module should have precedence, be loaded instead, the module installed with the kernel. TIA !

• Assign highest priority to my local repository

  - by Anwar Shah

  Original question was : "How to assign highest priority to local repository without using sources.list file" I have setup a local repository with packages I downloaded. I use it to avoid downloading the same packages over the Internet, when I need to reinstall my Ubuntu. It is a basic repository, created with apt-ftparchive packages . > Packages. I made this a trusted repository to avoid "unauthenticated repository" warning. (When you have a untrusted repository, apt or synaptic try to download the same packages over the Internet, 'cause it is trusted). I have been using this local repository for at least 1 years. But I have to always put my local repository line at the top of the sources.list file to use this. But this is annoying, since I must open a terminal and do some typing on it every time I reinstall Ubuntu, though there is a better tool software-properties-gtk. I cannot use this tool since it place the source line at the end of `sources.list. And the real problem is that, the apt or synaptic always download a package from the source which is mentioned earlier, without inspecting whether the packages are already available in the local repository. So, I have no choice but to place the local source at the top of sources.list doing terminal (I actually don't hate terminal, but I need a solution) . I have tried this method. But this does not help me. My preference file is this in /etc/apt/preferences.d/local-pin-900 Package: * Pin: release o=Local,n=ubuntu-local Pin-Priority: 900 My release file is this Origin: Local Label: Local-Ubuntu Description: Local Ubuntu Repository Codename: ubuntu-local MD5Sum: ed43222856d18f389c637ac3d7dd6f85 1043412 Packages d41d8cd98f00b204e9800998ecf8427e 0 Sources When I enable the apt-preference, the apt-cache policy correctly shows the preference, e.g. It shows the local repository has the highest priority. But when I do this sudo apt-get install <package-name>, apt tries to download it from Internet. But when I place my local-repo at the top, it installs from local repository. So, My question is - 'Is it possible to force apt to use local repository when the package is available in local repository, without explicitly placing "the local source" at the top of my repository list (e.g sources.list file) ?' Edit: output of apt-cache policy $package_name is as follows nautilus-wipe: Installed: (none) Candidate: 0.1.1-2 Version table: 0.1.1-2 0 500 http://archive.ubuntu.com/ubuntu/ precise/universe i386 Packages 900 file:/media/Main/Linux-Software/Ubuntu/Precise/ Packages It is showing that my local repository has higher preference, though it is not the one which comes first in sources.list file. Here is the output of apt-get install nautilus-wipe Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: nautilus-wipe 0 upgraded, 1 newly installed, 0 to remove and 131 not upgraded. Need to get 30.7 kB of archives. After this operation, 150 kB of additional disk space will be used. 'http://archive.ubuntu.com/ubuntu/pool/universe/n/nautilus-wipe/nautilus-wipe_0.1.1-2_i386.deb' nautilus-wipe_0.1.1-2_i386.deb 30730 MD5Sum:7d497b8dfcefe1c0b51a45f3b0466994 It is still trying to get the file from Internet, though I think it should be happy with the local one.

• dual boot Windows 7 and Ubuntu 11.04, black screen when loading Windows

  - by Sean

  I am proficient with Windows and not so much with Linux. Here is my story: Original system came with Windows 7, got openSUSE installed on the second hard drive, and dual boot for this setup worked fine. Wanted to switch to Windows 7 and Ubuntu 11.04 dual boot so I did a Windows system recovery and it appeared to give me back a fresh Windows 7 install. I then go to install Ubuntu 11.04 and the installer informs me I have multiple operating systems already installed. I go to the advanced partitioning option and sure enough Windows 7 is on /sda while openSUSE is still on /sdb. From here I followed this guide (How to dual-boot Linux and Ubuntu with two hard drives) after I had deleted all the openSUSE partitions on /sdb through the Allocate Drive Space tab of the installer. I make the /boot, swap, /, and /home partitions and set the GRUB into the MBR of the second disk (/dev/sdb). Everything installs fine. I reboot, Windows loads automatically, install EasyBCD and add an entry for Ubuntu into the Windows Boot Manager while assigning the type as GRUB2. Reboot the system and it now shows dual booting options for both Windows and Ubuntu. Problem is: while I can use Ubuntu fine when I try to boot into Windows it just gives me a black screen and after a little while the fans start running crazy. If I restart the computer I will sometimes get the message that my system was put into hibernation mode because the temperature got too high (90C) which I presume is in accordance with the fans going crazy. I have linked the output from the Boot Info Script below, any suggestions on how to fix this issue would be greatly appreciated!

• Python PyBluez loses Bluetooth connection after a while

  - by Travis G.

  I am using Python to write a simple serial Bluetooth script that sends information about my computer stats periodically. The receiving device is a Sparkfun BlueSmirf Silver. The problem is that, after the script runs for a few minutes, it stops sending packets to the receiver and fails with the error: (11, 'Resource temporarily unavailable') Noticing that this inevitably happens, I added some code to automatically try to reopen the connection. However, then I get: Could not connect: (16, 'Device or resource busy') Am I doing something wrong with the connection? Do I need to occasionally reopen the socket? I'm not sure how to recover from this type of error. I understand that sometimes the port will be busy and a write operation is deferred to avoid blocking other processes, but I wouldn't expect the connection to fail so regularly. Any thoughts? Here is the script: import psutil import serial import string import time import bluetooth sampleTime = 1 numSamples = 5 lastTemp = 0 TEMP_CHAR = 't' USAGE_CHAR = 'u' SENSOR_NAME = 'TC0D' #gauges = serial.Serial() #gauges.port = '/dev/rfcomm0' #gauges.baudrate = 9600 #gauges.parity = 'N' #gauges.writeTimeout = 0 #gauges.open() filename = '/sys/bus/platform/devices/applesmc.768/temp2_input' def parseSensorsOutputLinux(output): return int(round(float(output) / 1000)) def connect(): while(True): try: gaugeSocket = bluetooth.BluetoothSocket(bluetooth.RFCOMM) gaugeSocket.connect(('00:06:66:42:22:96', 1)) break; except bluetooth.btcommon.BluetoothError as error: print "Could not connect: ", error, "; Retrying in 5s..." time.sleep(5) return gaugeSocket; gaugeSocket = connect() while(1): usage = psutil.cpu_percent(interval=sampleTime) sensorFile = open(filename) temp = parseSensorsOutputLinux(sensorFile.read()) try: #gauges.write(USAGE_CHAR) gaugeSocket.send(USAGE_CHAR) #gauges.write(chr(int(usage))) #write the first byte gaugeSocket.send(chr(int(usage))) #print("Wrote usage: " + str(int(usage))) #gauges.write(TEMP_CHAR) gaugeSocket.send(TEMP_CHAR) #gauges.write(chr(temp)) gaugeSocket.send(chr(temp)) #print("Wrote temp: " + str(temp)) except bluetooth.btcommon.BluetoothError as error: print "Caught BluetoothError: ", error time.sleep(5) gaugeSocket = connect() pass gaugeSocket.close() EDIT: I should add that this code connects fine after I power-cycle the receiver and start the script. However, it fails after the first exception until I restart the receiver. P.S. This is related to my recent question, Why is /dev/rfcomm0 giving PySerial problems?, but that was more about PySerial specifically with rfcomm0. Here I am asking about general rfcomm etiquette.

• How to Change and Manually Start and Stop Automatic Maintenance in Windows 8

  - by Lori Kaufman

  Windows 8 has a new feature that allows you to automatically run scheduled daily maintenance on your computer. These maintenance tasks run in the background and include security updating and scanning, Windows software updates, disk defragmentation, system diagnostics, among other tasks. We’ve previously shown you how to automate maintenance in Windows 7, Vista, and XP. Windows 8 maintenance is automatic by default and the performance and energy efficiency has been improved over Windows 7. The program for Windows 8 automatic maintenance is called MSchedExe.exe and it is located in the C:\Windows\System32 directory. We will show you how you can change the automatic maintenance settings in Windows 8 and how you can start and stop the maintenance manually. NOTE: It seems that you cannot turn off the automatic maintenance in Windows 8. You can only change the settings and start and stop it manually. Can Dust Actually Damage My Computer?
