• How is time calculation performed by a computer?

  - by Jorge Mendoza

  I need to add a certain feature to a module in a given project regarding time calculation. For this specific case I'm using Java and reading through the documentation of the Date class I found out the time is calculated in milliseconds starting from January 1, 1970, 00:00:00 GMT. I think it's safe to assume there is a similar "starting date" in other languages so I guess the specific implementation in Java doesn't matter. How is the time calculation performed by the computer? How does it know exactly how many milliseconds have passed from that given "starting date and time" to the current date and time?

• Does it help to be core programmer of a product (product meant for social good ) for getting into Ph. D. in top university in USA say top 20?

  - by Maddy.Shik

  Hey i am working upon a product as core developer which will be launched in USA market in few months if successful. Can this factor improve my chance to get Ph.D. in good university(say top 20 in US). Normally good universities like CMU, standford, MIT, Cornell are more interested in student's profile like research work, under graduate school etc. I am not passed out from very good university its ranked in top 20 of India only. Neither did i do research work till now. But being one of founding member of company and developing product for same, i want to know if this factor can help and to what extent. For university with ranking lower than 20 what matters most is GRE General score and GPA but i guess top university must be appreciating a person's real efforts.

• How to Quickly Check If Your Computer Can Run a PC Game

  - by Chris Hoffman

  PC gaming isn’t quite as simple as console gaming. If you have a laptop with weak graphics hardware or an older PC, it’s important to check whether your computer can support a game before you spend your hard-earned cash. Gamers don’t have to upgrade their hardware as often as they used to. Even a gaming PC built years ago should be able to handle the newest games just fine. Laptops not build for gaming and older PCs are a different matter.

• Battery discharges while computer is off

  - by Nuno Finote

  I bought a hp 15-r003np 2 weeks ago and installed ubuntu 14.04 LTS with dual boot (to windows 8). When i shutdown ubuntu, in the next day battery has 85% of charge, despite the computer shutdown. If i power off in windows battery charge is 100% in the next day. Does anyone have noticed the same problem? I think the network adapter is not on wol mode, seen via windows network config properties. I need help to solve this problem... (it's not right to work around restarting to windows to do the shutdown properly...)

• Computer Arithmetic - Binary for Decimal Numbers

  - by MarkPearl

  This may be of use to someone else doing this course… The Problem In the section on Computer Arithmetic it gives an example of converting -7.6875 to IEEE floating point format. I understand all the steps except for the first one, where it does the following... 7.6875 (base 10) = 111.1011 (base 2) I don't understand the conversion - I realize that 111 (base 2) = 7 (base 10), but how does the .6875 part relate to the .1011? Or am I totally off track with this? The Solution The fractional part of the decimal to binary conversion is done as follows: 0.6875 x 2 = 1.375 = 0.375 + 1 (Keep the 1 separate) 0.375 x 2   = 0.75   = 0.75    + 0 0.75 x 2    = 1.5      = 0.5      + 1 0.5 x 2     = 1.0       = 0.0       + 1 The bit pattern of 0s and 1s on the right-hand side gives you the fractional part. So 0.6875 (base 10) = .1011 (Base 2) See also Stallings, chapter 19.

• Weird graphical errors in console and on computer shut down

  - by Mark A.

  I am all new to Ubuntu (and Linux in general) and I am experiencing some strange graphic on my screen. Console #1 (ctrl+alt+f1): Exactly the same happens on all the other consoles (2-6), and the consoles don't seem to work. And I see the same when I hibernate or shut down my computer, but not when I suspend it. I was thinking that it may have something to do with the SiS 671 video driver work around that I use? http://ubuntuforums.org/showpost.php?p=11476910&postcount=773 Any ideas how to fix this?

• How to change address and name of the computer in linux Ubuntu

  - by Byakugan

  I have troubles again after upgrading Linux to version 12.04 - When I try to update progams and files with "apt-get update" it says something like there is no address added to your computer name. So my hostname has name "Marco" and my hosts file has line "127.0.0.1 Marco" So where is problem? Where should I change my name to get it right for updates? Thank you. Before on version 11.10 it was working fine. W: Failed http://en.archive.ubuntu.com/ubuntu/dists/precise-updates/main/i18n/Translation-en Something bad happened in the translation "en.archive.ubuntu.com: http" (-5 - The machine name is not assigned to any address)

• computer doesn't boot from usb ubuntu installer when trying to install it alongside windows 7

  - by ali

  I'm very noob at linux and installing techniques. I want to install ubuntu 12.04 from bootable usb flash alongside windows 7 ( also tried live CD but now working ) but computer is not booting from usb flash or LIVE-CD and boots windows 7 ( acer aspire 4750g ). and of course I have set the bios priority in the right way. There is one important point to tell that I have installed Fedora 16 on my laptop successfully and now I have it on my system. when I was trying to install fedora i got some error and searched about it and got this point that I should delete a .efi file and then installation went right. In this case , what should I do to solve the problem? ( I also don't need my Fedora anymore )

• Phone pictures not showing in UbuntuOne folder on computer

  - by user34924

  I downloaded the Android app for my phone and set it up to move my pictures from the phone into UbuntuOne. When I go to the UbuntuOne web site the folder shows up and I can view the pictures after I download them. But when I open the UbuntuOne folder on my laptop, the folder with the pictures from my phone isn't listed. How can I get the picture folder to show up in the UbuntuOne folder on my laptop? I was hoping this would be an easy way to get photos from phone to computer.

• Creating a bootable USB recovery drive to be used by someone who isn't computer savvy

  - by David

  I am looking for a way to prepare an image of an Ubuntu machine which would be bootable and installable in the easiest way possible. I'm actually preparing an Ubuntu machine for someone living far, and not computer savvy. If he ever has troubles with his installation, he could just put a USB drive in, boot the machine and everything would be resetted for him. I know there are many methods of creating/loading an image of a drive, but the ones I've found so far have complicated menus with several options to choose from, etc. Ideally, perhaps only asking a Yes/No question such as "Would you like to reinstall?" would be great. Does such a tool exist? Thank you in advance!

• Computer Freezes After GRUB

  - by paulmcg421

  Ok so I've just built my first computer and have got it running, here are the specs: Asus P8Z68-V PCI-E LX Motherboard, Intel Core i5-2500K, Patriot Memory 8GB (2 x 4GB), Viper Xtreme Series PC3-15000 1866MHz CL9 Division 2 Edition Memory (PXD38G1866ELK), Gigabyte ATI Radeon 6850 820MHz 1GB PCI-E HDMI OC Windforce 2x 500w Ezcool 24pin psu as standard. The only thing I haven't bought new is the hard drive, it's a 250gb that I removed from an Acer Aspire M5100 that I was using till now with no OS Problems. On start up it runs fine but is unresponsive after the GRUB menu disappears to load Ubuntu (Oneric Ocelot). The keyboard lights then turn off and the screen eventually returns that there is no signal. Is there anything that I could be missing from building? (This is my first attempt at building my own PC) Any input would be appreciated, thanks !

• How To Remote Control Your Home Computer From Anywhere With VNC

  - by Chris Hoffman

  VNC allows you to remotely access a computer and use its desktop, either over the Internet or from another room in your house. Windows includes a Remote Desktop feature, but it’s only available in Professional editions of Windows. Some people may prefer TeamViewer or another service instead, but VNC allows you to install and manage your own server without using a centralized service. VNC clients and servers are available for all platforms, but we’ll be covering Windows here.

• Computer won't wake from hibernate

  - by Icoo

  So I have a pretty dumb problem...I accidentaly pressed Hibernate while trying to Restart...since then my computer wont boot into Ubuntu anymore (through normal mode or single user mode - rescue mode that is)...all I get is: mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys/ on root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or dirctory Target filesystem doesn't have requested /sbin/init. No init found. Try passing init= boot arg. BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) Obviously I tried to fire up the Live CD and run fsck (or e2fsck) from there (or just try to do a Check of /dev/sdb1 my partition via gparted - which is basically the same thing). But it doesn't allow me...both gparted and fsck say that the device is busy (I can't even mount it in the LiveCD to rescue data)...umount /dev/sdb1 says its not mounted...any ideas?

• Ubuntu 12.04 - Read only file system+computer crash/freezes after an update that got interupted

  - by user288542

  I've run into an error with Ubuntu while I was updating it. During the update my power went out and interrupted the update. When I finally got power and booted my computer, I received an error, telling me to remount ./ and basically told me I could press S to skip or F to fix. (I forgot exactly what it said) but anyways, I originally pressed F to fix, but that didn't solve the problem, so then I went into the terminal and I tried to remount that way, but I couldn't execute because it's stuck in "file system read only." Sorry, my description of the problem is dull. I'm debating on just reinstalling, but I have a ton of files I would like to keep, about 3+ years worth of websites I've built. Is there a proper way to fix this?

• My ethernet connection is not working but it is detected by my computer

  - by smithy545

  I'm setting up an old computer with ubuntu server 12.04. I wiped the drive and went through the installation fine but afterwards the ethernet would not work. It's physically connected to the router and the card is recognized by lspci(SiS 900) but it won't connect at all. I've plugged in and installed the drivers for a wifi adapter and it's worked with the same router. Just so you know I've turned it on and off plenty of times. Any help would be appreciated.

• Limiting what resumes computer from suspend

  - by user1399195

  I'm having a ton of trouble getting Suspend to work with my laptop. I want to start using Ubuntu but this is a pretty important aspect since I take my laptop with me everywhere. Anyways, I wanted to narrow down the possible problem with my laptop. What happens is that when I suspend my computer, within seconds, it just boots back up. I have changed /proc/acpi/wakeup to where everything is disabled but that did nothing. Is there a way where I can disable every feature from waking up the laptop except the power button?

• Computer freezes up

  - by Namaachi

  I am using the latest Ubuntu OS and up-to-date Chrome browser. Occasionally when I am working at a 5 hour stretch, the computer will freeze up completely and I will have to close down manually and reboot. When this happens I lose the material I have been working on as I cannot save it. And I often receive a notice at this time saying that my profile is not available or that I do not have a profile. I am an Ubuntu user not a technician and do not know what to do about this problem.

• CD help and Dead Computer[SOLVED]

  - by fifi_defluffy

  I am trying to burn 12.04 on a CD. Should be it working or is it not? After reading a couple of other forums that relates to this question, they say to use a 700MB CD which I am but again is not working. Another question is that the reason for this is because I have a School Desktop which I use and the OS seems to have crashed and that OS files seem to be missing so this looks like an option at the moment. So basically, Can't burn it on a CD (says its too small) and trying to rework a partial dead computer...
