• Cloned screen on monitors with different resolutions

  - by jrtokarz

  I want to set up a system with two displays connected. One display will be a 22inch monitor with a native resolution of 1920x1080. The other display is a 19inch display native resolution 1024x768. I want to clone the 1920x1080 display on to the 1024x768 display. I have tried this and the 1080p image is squashed on to the smaller display. Is it possible to set it up such that rather than squashing the image, I can get the smaller display to use a virtual resolution of 1920x1080 and pan the display?

• Skype Silent Mode

  - by jack

  So Skype has a silent mode: e.g. it won't alert you in any way about incoming calls/messages. I'd like to use that mode while working to keep Skype from distracting me. I'd rather not quit the program or signoff during that time. Is there a simple way to put Skype in that mode? There's an option for it in their SDK but not in the software. There are third party apps that do it (among other things), but there doesn't seem to be a simple solution for this. Help please!

• Windows 7 - sharing file - slow seek time?

  - by progtick

  I do not want to copy the files. I simply have video files (.flv) on one computer and I would like another computer user to watch them without copying. Playback is fine, but seek time (as in if you move the cursor to skip some portion of the video) takes forever! I thought wireless speed might be the culprit, so I wired the two computer. Maybe I saw some improvement but still so bad. It's 1 Gbps! (I know real speed will vary, but before I monitor real speed and such, do I have reasonable issue? Or am I bound to have very slow seek time?) What is going on? I must mention some of these files are huge!

When I call the html page then .js file also included. In the .js,I am using $('div').live('pageshow',function(){}). I am calling the html file from the .js(using $.mobile.changePage("htmlpage")). My problem : consider, I have two html files. second.html file is called with in the one.js. when I show the second.html, that time one.js is reload again. I am getting the alert "one.js" then "second.js" Please help me. Thanks in advance. Please point out my mistake.

But I need fourth.js alone). I tried to use the $.document.ready(function(){}); but that time .js did not call. :( :( :(

• Monitoring/logging a malfunctioning internet connection

  - by Pekka

  I have a mysterious internet connection problem: Every 15-20 minutes, the connection will become very slow, and take 2-3 minutes for anything to load. I've had a technician from the ISP over here to test the hardware, and everything is in pristine condition. They have no other explanation than a configuration error on my machine, a possibility I can exclude 90% because I'm experiencing the same problems with another machine. I will have to monitor the situation now, and I would like to run a program that logs when internet connections become slow. I thought about putting something together using at and wget. Does anybody know of some other tool for this that does this out of the box - maybe something with an adjustable request frequency, logging connection speeds etc.?

• Does anyone know about nagios plugin that uses nmap and does port checking??

  - by Eedoh

  Hi to all. I need to monitor open and closed ports on dozens of hosts. I've found a Nagios plugin that does what I need, but I would have to use this script through nrpe. Some of the hosts are powered by linux and they all have perl installed. But some of them are Windows machines, and it's not convenient for me to install perl on every one of them. That's why I can not use this plugin. I hope that there's Nagios plugin that uses nmap, or something similar, so it could check ports on every host remotely, without installing plugins on remote hosts, only on server.

• How to calculate time spent for Linux system administration?

  - by Jaakko

  I would love figuring out how much time I actually have spent in shell performing administrative duties. For billing of course, this information is not sufficient, but it would be helpful to figure out how much time I have actually spent in shell. My question is: How anyone got tips on how to calculate time spent in shell (in hours + minutes), let's say per user account? Could anyone recommend a software that could be used to analyze this time? Optionally I would like to know about ways how to categorise time spent (e.g. 1 hour for Apache, 2 hours for Samba, etc.) Also, your takes on how you monitor your admin time, are also much appreciated! To narrow down the problem, I am specifically interested in ways of tracking time spent in shell for Linux system administration

• How does the build quality of laptops compare?

  - by pgwillia

  I'm looking to replace my 5 year old laptop. I want my next laptop to endure at least this long. I typically have Thunderbird, Firefox, Eclipse Java IDE, Skype, a ssh session, and Apache Tomcat running. I'm currently running Karmic Ubuntu, but am agnostic about operating system and would move to Win 7 or OS X. I frequently travel with this computer. I also value battery longevity and power conservation (if possible). Above all I'm looking to minimize cost. I think the hardware that best meets my needs is an Intel i7 processor, 8 GB RAM, 100GB @7200 rpm or SSD hardrive, and about 15 inch monitor. These specs are met by most brands. Does anyone know specific pros/cons and build quality for Macbook Pro, Lenovo Thinkpad (W510 or T510), Sony's VPC-F1190, and ASUS G Series G73JH-X1 NoteBook? Are all i7 processors created equal? Do you have other suggestion that meet my needs?

• 802.11 Capture Frame

  - by ALi

  I am using wireshark in monitor mode to capture all the frame. I buffered all the QosData in order to calculate the biterate of each station on the network. I calculate the biterate but it is not an accurate value. what i need to know is when the station use the network alone and when it uses it with another station? i know if two station with different wifi card for exemple ( st1 802.11g 54 Mb/s, st2 802.11n 300 Mb/s) if st1 uses alone the line the biterate used is 28 MB/s and if st2 uses alone the network the bit rate increase to approximately 150Mb/s but if the two station use the network at the same time the st1 lost about 80% of its bit rate because of the st1 wifi card thx in advance

• Old notebook internal display randomly not recognized

  - by jfcfar

  I have an old Acer TM4001 notebook. If the laptop is powered-off, with the lid closed, when I power it on, it generally works. Then, without touching anything, if I reboot the computer the internal display wil not work anymore. To make it working again I need to shut down the pc, close and reopen the lid and then turn it on. If I close and reopen the lid if it is not working after power the pc on, it won't work. When the screen is working, closing and opening it has no effect (the data cable seems ok). The external monitor always works as expected: If the internal display is not detected, the external will be the main (and only) display. This is not OS-related. When the screen is not working I cannot see the POST. What could be the cause for this?

• Why are network printers not available in the Add Printer Wizard...when run over a network?

  - by Kev

  From a Windows 2003 server machine I browsed the network to an XP client (\computername in Explorer) then double-clicked Printers and Faxes and then Add Printer. In the wizard, normally the second screen asks if you want to install a local printer or a network printer. Well, in this case, it seems to assume I want a local printer, because the second screen is what would normally be the third screen if you chose local printer and clicked Next. I want to install a network printer on a remote machine for its local users. Is this not possible? If not, why not?

• bad ram or bad motherboard

  - by user39508

  I have a computer which crashes after about 5-45 seconds of operation. It can run memtest86+, and it doesn't display any errors, but it doesn't prevent it from crashing within the time frame listed above. The heat sink appears to be installed correctly, and I don't think it is related to overheating. The motherboard is connected to the ram and a monitor, nothing else is installed. The processor is an atom 330, running memtest86+ 4.0. Any insight into if the ram is bad or if it is the motherboard/psu/cpu? Thanks!

• Why does waking a PC up with a timer act differently than with the power button?

  - by Dan Rasmussen

  I have a Windows 7 machine set up as a server. It has no monitor and is only accessed through remote desktop. I set up two scheduled tasks, one to put the computer to sleep at night and another to wake it up in the morning. When it's woken up from sleep via a timer, it stays awake for only a couple minutes before going back to sleep. When woken up by pushing the power button, however, it stays awake all the way until the sleep timer. Why does my PC behave differently in these two scenarios? I have set the PC not to prompt for a user's password on wake, since I worried that the login screen might follow different power rules. I tried SmartPower Configuration but had the same problems. I can provide more details if questions are asked in the comments, but I'm not sure what's relevant.

• Duplication of menu items with ViewPager and Fragments

  - by Julian

  I'm building an Android Application (minimum SDK Level 10, Gingerbread 2.3.3) with some Fragments in a ViewPager. I'm using ActionBarSherlock to create an ActionBar and android-viewpagertabs to add tabs to the ViewPager just like in the Market client. I have one global menu item that I want to be shown on every tab/fragment. On the first of the three tabs I want to have two additional menu items. But now two strange things happen: First if I start the app, everything seems to be fine, I can see all three menu items on the first page and only one item if i swipe to the second and third tab. But if I swipe back to the second tab from the third one, I can see all three items again which shouldn't happen. If I swipe back to the first and then again to the second tab, everything is fine again. The other strange thing is that every time I rotate the device, the menu items from the fragment are added again, even though they are already in the menu. Code of the FragmentActivity that displays the ViewPager and its tabs: public class MainActivity extends FragmentActivity { public static final String TAG = "MainActivity"; private ActionBar actionBar; private Adapter adapter; private ViewPager viewPager; private ViewPagerTabs tabs; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.volksempfaenger); actionBar = getSupportActionBar(); adapter = new Adapter(getSupportFragmentManager()); adapter.addFragment(getString(R.string.title_tab_subscriptions), SubscriptionGridFragment.class); // adding more fragments here viewPager = (ViewPager) findViewById(R.id.viewpager); viewPager.setAdapter(adapter); tabs = (ViewPagerTabs) findViewById(R.id.tabs); tabs.setViewPager(viewPager); } public static class Adapter extends FragmentPagerAdapter implements ViewPagerTabProvider { private FragmentManager fragmentManager; private ArrayList<Class<? extends Fragment>> fragments; private ArrayList<String> titles; public Adapter(FragmentManager fm) { super(fm); fragmentManager = fm; fragments = new ArrayList<Class<? extends Fragment>>(); titles = new ArrayList<String>(); } public void addFragment(String title, Class<? extends Fragment> fragment) { titles.add(title); fragments.add(fragment); } @Override public int getCount() { return fragments.size(); } public String getTitle(int position) { return titles.get(position); } @Override public Fragment getItem(int position) { try { return fragments.get(position).newInstance(); } catch (InstantiationException e) { Log.wtf(TAG, e); } catch (IllegalAccessException e) { Log.wtf(TAG, e); } return null; } @Override public Object instantiateItem(View container, int position) { FragmentTransaction fragmentTransaction = fragmentManager .beginTransaction(); Fragment f = getItem(position); fragmentTransaction.add(container.getId(), f); fragmentTransaction.commit(); return f; } } @Override public boolean onCreateOptionsMenu(Menu menu) { BaseActivity.addGlobalMenu(this, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { return BaseActivity.handleGlobalMenu(this, item); } } Code of the fragment that shall have its own menu items: public class SubscriptionGridFragment extends Fragment { private GridView subscriptionList; private SubscriptionListAdapter adapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setHasOptionsMenu(true); } // ... @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { inflater.inflate(R.menu.subscription_list, menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { // ... } }

• Connecting OS X MacBook Pro to DirecTV DVR

  - by user14293

  I have a DirecTV DVR which soon will be replaced. The local phone carrier has wired fiber-to-the-door and that DirecTV sat service will soon be history. I have irreplaceable video recordings on the DVR's disk I would like to salvage. I'd like to connect my MacBook Pro (OS X 10.5.3) to the DVR (male HDMI to male Thunderbolt) and treat the MAC as a TV monitor. I'd like to capture the video stream to a file and then burn it to DVD. This is for my use only, not for distribution. Still researching video capture. Don't yet have a solution. Maybe there isn't one. Any ideas?

• Does WD Drive Lock encrypt the data?

  - by ssg

  I wonder if WD Drive Lock ineed encrypts the data on a Western Digital My Book Essential device or just puts a firmware-level password on the device. If it's just a password the data surely could be retrieved by a third party. I could not find anything on about that on user manuals. I found a blog saying "data is secured with AES256" bla bla but that doesn't say anything about if the password could be compromised or not. Because I don't see any delays when I add/remove the password. On the other hand when I enable BitLocker, it takes hours before it encrypts everything with my password.

• How to view status of software RAID 1 resynching?

  - by tputkonen

  I have two 500 GB disks and yesterday I mirrored first drive to the second one using software RAID 1. PC has now been on for 30 hours. Both disks say "Resynching", but there is no progress indicator. In addition, there is a small yellow exclamation mark on both disks. My questions are: How long could the synch take for 500 GB drive with about 150 GB of data? PC has 4 GBs of RAM and AMD dual core 4000+ Is there a way to monitor status of the synching? How can I check what the exclamation mark means?

If someone can provide any clue or suggestion that what happened and what should I do, appreciated. thank you.

Would it be possible to plot the above data in a chart or coordinate system. Where the each plot should be a summary of all sales in the same map coordinate. Also a similar chart of order count would be nice to have.

• Computer to Tv cable question

  - by Keith D

  Hi all. Heres my query : I have a PC with all the usual outputs and a couple of TVs in the house with inputs to connect to a computer. Now, what i would like to do is get rid of cable TV and using the input into the spliters in the basement,( ie. where the input cable from outside actually feeds the system ) have the computer become the "Cable supplier" ( so to speak ) and have the output ( via some sort of box ) from the computer, convert what is on my monitor into an RF signal that is then fed into the cables in my house and ultimately to each TV / room . I don't know if there is such an item but would welcome any thoughts you might have on such a set up. I am not into HD or the like, so the picture quality needs only to be watchable, not HD. I don't want to have to set up seperate cables to feed the audio on each TV. Thanks in advance!

• How do I compare binary files in Linux?

  - by frustratedCmpNoLongerUser

  I need to compare two binary files and get the output in the form <fileoffset-hex <file1-byte-hex <file2-byte-hex for every different byte. So if file1.bin is 00 90 00 11 in binary form and file2.bin is 00 91 00 10 I want to get something like 00000001 90 91 00000003 11 10 What is the easiest way to accomplish the goal? Standard tool? Some third-party tool? (Note: cmp -l should be killed with fire, it uses a decimal system for offsets and octal for bytes.)

• Focus Follows Mouse or Sloppy Focus on Mac OS X

  - by jtimberman

  "Focus follows mouse" or "sloppy focus" is a feature common to X11 window managers on Linux/Unix, including GNOME, KDE, CDE, XFCE and window managers like Enlightenment, Fluxbox and Window Maker. It is also available via TweakUI on Windows. Some individual applications on OS X, like iTerm support it. What is it? Simply put, the window where the mouse pointer is has focus, rather than having to click a window for it to gain focus. Does the native GUI for OS X support this, with some hidden setting? Or, is there a good third party application that will do this?
