  • What caused Cyclic Redundancy Check error on my BitLocker-enabled external hard drive and how to fix it?

    - by Forgiver
    I have an external hard drive that is connected to my computer (Windows 7 Ultimate 64 bit) via a USB port. BitLocker has been activated on the hard drive to protect the data. Yesterday I started downloading a huge data from the internet but now it failed to complete because of CRC error. I tried to repair it with chkdsk f:/r where f is the drive letter of that hard drive. There are many messages reporting "unreadable" as follows: What caused Cyclic Redundancy Check error on my BitLocker-enabled external hard drive and how to fix it?

  • A Quarter Century of SPARC

    - by kemer
    You might have missed an interesting milestone: the 25th anniversary of SPARC. Twenty-five years! Almost 40% of my life: humbling, maybe a little scary. When I joined Sun Microsystems in 1988, SPARC was just starting to shake things up. The next year we introduced the SPARCstation 1, which had basically triple the performance of our Motrolla-based Sun–3 systems. Not too long after that, our competition began a campaign of “SPARC is dead.” We really distressed them with our success, in spite of our small size. “It won’t last.” “It can’t last!” So they told themselves. For a stroll down memory lane take a look at this page. I remember the sales meeting we had in Atlanta to internally announce the SPARCstation 1. Sun hadn’t really hit the big times, yet. Our much bigger competitors viewed us as an ill-mannered pest, certain of our demise. And, why wouldn’t they be certain: other startups more our size, such as Apollo (remember them?), Silicon Graphics (they fought the good fight!), and the incredibly cool Symbolics are memories. Wait! There was also a BIG company, DEC, who scoffed at us: they are history, too. In fact, we really upset them with what was supposed to be an internal-only video production that was a take-off on Bruce Lee movies, in which we battled the evil Doctor DEC – complete with computer mice (or is that “mouses”?) wielded like nun chucks with the new SPARCstation 1 somehow in the middle of everything. The memory is vivid, but the details hazy. After all, that was almost a quarter century ago. So, here’s to Oracle’s SPARC: still going strong after all these years. – Kemer

  • Some info about SD card patitions after the use of the dd statment and some oiters doubts?

    - by AndreaNobili
    I am not very experienced using Linux and I have the following situation that cause me some doubts. I have wrote RaspBian (the RaspBerry linux distribution) on an SD card using Ubuntu dd statment: sudo dd if=2014-01-07-wheezy-raspbian.img of=/dev/sdb bs=1024 So if now I perform the fdisk -l statment I obtain that I have 2 partitions related to my SD card, that are the followins: Dispositivo Boot Start End Blocks Id System /dev/sdb1 8192 122879 57344 c W95 FAT32 (LBA) /dev/sdb2 122880 5785599 2831360 83 Linux And now the first doubt: the dd statment create on the SD card two partitions: 1) /dev/sdb1 that is a litle FAT32 partition (what it means (LBA)?) 2) /dev/sdb2 that is a larger Linux ext3 partition Ok...the doubt is: why it also create to me a FAT32 partition and not only a Linux ext3 partition? Ok...if I go into my computer resource I can see a device (related to my SD card) into the devices list that contains some RaspBian file, following a screenshot: And if I see the property of this device I obtain this: So, looking at the previous screenshot it seems to me that this is the small FAT32 partition, and now I have the followings doubts: If it is the smallest FAT32 partition, what contains? The RaspBian boot or what? Why, in the devices list, I have only the FAT32 partition and not also the Linux one (/dev/sdb2), to see it have I to mount it? how? Tnx

  • Third-party Information Screen Opening Blank

    - by Jacob
    I'm working with a client who is trying to use our software, which accesses information (sends & receives) from a third-party website. When this client tries to access these pages, a window opens, as expected, but is completely blank and no error message is received. This is the first time I've seen this with many other clients successfully using this product, which leads me to believe that it has something to do with the settings on the computer somewhere, but cannot figure out what might be happening. Windows Server 2003 R2, Standard Edition, Service Pack 2. Firewall is already off. Tried AVG on & temporarily disabled.

  • How to get started in the development industry? [closed]

    - by Peter Fren
    My life is coding. I was born in 1982 and my first computer was an amiga. I started learning Amiga BASIC. To cut a long story short, I know many things about several programming languages. Being unemployed(I achieved the german abitur, should be similar to a high school degree and I studied a few semesters of mechanical engineering in 2002(I learned JAVA back then)) I have no idea how to use this ability. I have never done commissional work, every task I solved was based on my own wishes and desires. I do not know how to write a FSD or PRD or put it into code. So the question is, why should anyone hire me? I specialized in kinect development but all jobs I applied for on odesk and similar were awarded to others without me knowing why. I don't know what I should do with my skills professionally. What do you suggest? As this board has weird rules, tell me where to find answers if this is the wrong place.

  • Safari on Mac OS X lasts beyond Empty Cache

    - by Mitch
    So, I broke a website with some server changes oops. I roll back the changes I made, hit cmd-R, and oh noes, it is still broken. But I relax thinking, there must be something held in safari's cache so I press the handy 'Empty Cache' button. Hit cmd-R for refresh it is still broken. I'm really worried that I've done it and broken something bigtime. But first decide to check on a hand win xp computer, and voila it works. So the question is how do you "really" clear the cache w/o restart safari, I have many browser windows open a restart every time I make a server side change will ruin me. Any suggestions? Thanks!

  • Windows 8 doesn't automatically join Wi-Fi network if Ethernet connection is active

    - by Herb Caudill
    In Windows 7, my laptop would automatically join both an Ethernet network and the Wi-Fi network in my house (both going through the same router). In Windows 8, if the Ethernet connection is present, it doesn't join the Wi-Fi network at all. The reason I noticed this is that if Wi-Fi isn't active, I don't see my AirPlay speakers. My wireless printer is also unavailable until I manually connect to Wi-Fi. To recap: When I turn on my computer and it's connected to Ethernet, this is what my Network Connections control panel looks like: After I manually join my Wi-Fi network, it looks like this: I would prefer for it to join both networks automatically on startup, the way it did in Windows 7. Is there a way to make this happen?

  • Host a SSTP VPN Server on Windows 8

    - by Maarten
    I have a small server computer running Windows 8 at home. Currently it is hosting a PPTP VPN server using the build-in Windows 8 functionality for that. What I would want is something more secure, like an SSTP VPN server. However, I can't find any functionality of windows 8 or 3rd party software that can HOST a SSTP vpn server on Windows 8. I've only seen Client stuff and vpn pass trough services via google, all which i don't want/need. The only HOST stuff i find via google is the PPTP i set up currently. Is there any way of hosting a SSTP VPN server on my home machine? Thanks in advance, Maarten

  • Getting around the FAT32 4GB file size limit

    - by Aesir
    I recently purchased a 32GB USB 3 stick that was formatted FAT32. I plugged it into my computer and attempted to copy a film onto it, the file was over 4GB however and it would not let me copy the file across because of the 4GB file size limit imposed by FAT32. After some googling I found that I could format my USB stick to have an exFAT format which would mean I could put files onto the stick greater than 4GB in size and the drive would work on both my Mac and my PC. The problem with this solution is that my PS3 cannot detect the USB stick when it is formatted with exFAT. I would like to know if there is a way I can have my USB stick formatted so it can have files greater than 4 GB and work on my PC, Mac and PS3.

  • How can I remove the ssh last login info?

    - by Gnijuohz
    Whenever I log into a server using ssh. The prompt gives me "last login" information. I was wondering where this information comes from. How can I remove this record so when someone else log into the same server, the person would see my login info with my ip in it? So how can I do this? For the record, I am not hacking someone's computer and the server runs Ubuntu 12.04. EDIT: which file logs this kind of information? If I find the file, then I can do anything to it as root. Thanks.

  • accidentally concatenate a large file on a remote system

    - by Dan
    Every once in a while on a computer I'm ssh'd into, I will accidentally type "cat largefile.txt" and my screen will start rushing with text for the next 10 minutes. I'm always working in a screen session, so my current solution is to just log out and then log back in, and since it can go 100X faster when I'm logged out, it'll finish in the short time it takes me to type my password in again. Is there a better way? Either involving the fact I'm in a screen session? Or a way to do this within SSH? What doesn't work: detaching from the screen session (doesn't respond until file is done outputting) trying command to move to a different window in the screen session (also doesn't respond) typing ctrl+C to kill cat command (also doesn't respond, probably because the command is done and the buffers just have to catch up)

  • Homegroup and NTFS permissions

    - by bytenik
    I'm running a copy of Windows 7 as a "server" at my home. I have several file shares that I want to make available to specific users only. I've modified the NTFS permissions to only allow these users to access their respective shares. However, while a locally logged on user can access the actual folders just fine, over the network the remote access is authenticating as HomeGroupUser$ rather than the actual user in question, as shown by the Computer Management panel for shares. I do have matching user accounts (i.e. my username locally is abc and a parallel account with username abc and the same password exists on the server machine). I don't want to disable homegroup because there are other shares where homegroup authentication would be desirable, especially for some people where they don't have a parallel account. Is there a way to get the system to authenticate first by matching username, and then by homegroup authentication if there's no matching user?

  • How to Manage and Use LVM (Logical Volume Management) in Ubuntu

    - by Justin Garrison
    In our previous article we told you what LVM is and what you may want to use it for, and today we are going to walk you through some of the key management tools of LVM so you will be confident when setting up or expanding your installation. As stated before, LVM is a abstraction layer between your operating system and physical hard drives. What that means is your physical hard drives and partitions are no longer tied to the hard drives and partitions they reside on. Rather, the hard drives and partitions that your operating system sees can be any number of separate hard drives pooled together or in a software RAID Latest Features How-To Geek ETC Inspire Geek Love with These Hilarious Geek Valentines How to Integrate Dropbox with Pages, Keynote, and Numbers on iPad RGB?

  • does any sync software find files that have moved paths within a folder?

    - by kpierce8
    Say I have a pictures folder which I reorganized on one computer. I'd like to use that directory as the base and compare it with another version on a backup drive. Will any sync/compare program find that a file in one folder has moved locations within a compare folder. For instance say I reorganized my pictures from trips into folders by year with the trips folders inside each year folder. If I use a regular compare utility I wind up with two copies of everything that's moved in different locations.

  • Memory limiting solutions for greedy applications that can crash OS?

    - by Hooked
    I use my computer for scientific programming. It has a healthy 8GB of RAM and 12GB of swap space. Often, as my problems have gotten larger, I exceed all of the available RAM. Rather than crashing (which would be preferred), it seems Ubuntu starts loading everything into swap, including Unity and any open terminals. If I don't catch a run-away program in time, there is nothing I can do but wait - it takes 4-5 minutes to switch to a command prompt eg. Ctrl-Alt-F2 where I can kill the offending process. Since my own stupidity is out of scope of this forum, how can I prevent Ubuntu from crashing via thrashing when I use up all of the available memory from a single offending program? At-home experiment*! Open a terminal, launch python and if you have numpy installed try this: >>> import numpy >>> [numpy.zeros((10**4, 10**4)) for _ in xrange(50)] * Warning: may have adverse effects, monitor the process via iotop or top to kill it in time. If not, I'll see you after your reboot.

    the TCP/IP stack is smashed, thats why no LAN-Connections are running. I want to download the LAN drivers from another computer and uninstall and reinstall the LAN devices on this system. Hopefully that should recreate the stack. But what to download? What uninstall? How to install? Windows Vista is protected against such changes, so how to achieve that job? please help.

What can i do as next step or which opportunities are left?

  • Best memory-efficient web browser for Ubuntu?

    - by Steve K
    I've installed Ubuntu 10.10 on an old laptop with only 756 MB of RAM, Pentium M 1.6 processor. I'm using Google Chrome 11.0 (dev channel) for web browsing, and it appears to be using up most of my memory and processor time. Does anyone know of a better browser than Chrome on Ubuntu, for an older computer like mine? I'm new to Ubuntu, so there may also be tweaks I can make to my existing system to have it perform better. But right now it's pretty slow when I've got ~5-10 tabs open. Related question: memory-efficient web-browser

    So I'm a big fat idiot. I installed Ubuntu 11.04 on my school's laptop, and here's come the time that I have to turn it back in. I wrote GRUB to the Master Boot Record, thinking it wasn't going to be permanent. So, fast forward to yesterday.

  • HDMI Sound for HTPC

    - by Brent Arias
    I have the (perhaps) the same problem as stated in this other HDMI sound to HTPC question. I tried the advice of clicking on the speaker in the system tray. I can see the HDMI audio device I want to use. That device claims to be functioning properly. But there is no sound, and it won't let me select it as the active audio device. When I click on the troubleshooter, it says that there are no speakers connected. I would think this is because my computer us unable to pipe sound through the video card (preventing the HDMI from carrying it), except that it truly claims that it has an HDMI sound device that is working correctly. So I'm not sure what is wrong at this point. Thoughts? My system is Windows 7 x64. In case it makes a difference, the video card I'm using is this GeForce GTX 560
