    I have and asus r500v with 750 gb gpt system uefi motherboard core i7 3610qm, nvidia geforce gt, with ubuntu and w7 dual boot, I had problems installing ubuntu because of the grub but I fix it with https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/807801, but I still have the problem of "warning: the partition is misaligned by 3072 bytes. this may result iin very poor performance. Repartitioning is suggested" in every linux partitioin I made and my 750 gb is not being used at the maximun capacity it only uses 698 gb. I want to make partitions so that the warning doesnt show up and I can use the maximum capacity of the HDD, as I did with another dual boot laptop (compaq presario cq40). I have the following partitions: unknown 1.0Mb: partition type: lynux Basic DAta partition, device: /dev/sda2 Usage: --, Partition flags: --, partition label:-- warning: the partition is misaligned by 3072 bytes. this may result in very poor performance. repartitioning is suggested. -system 210 Mb FAt, usage: Filesystem, partition type: EFI system Partition, Partition Flags:--, Label: system, Device: /dev/sda1, partition label: EFI system partition, Capacity 210MB, avilable:--, Mount Point: mounted at /boot/efi -134 Mb NTFS, usage: filesystem, partition type: linux basic data partition, partition flags:.--, device: /dev/sda7, partition label: --, capacity: 134MB,available:--, mount point: not mounted -OS 250 GB NTFS, usage: file system, partititon type: linux basic data partition, partition flags: --, type: NTFS, label: OS, device: /dev/sda3, partition label: basic data partition, capacity: 250 GB, available:-, mount point: not mounted -10GB FAT 32, usage: filesystem, partition type: EFI system partition, partition flags:--, type: FAT 32, label: --, device: /dev/sda4, partition label: --, capacity: 10GB, available:--, mount point: not mounted warning: the partition is misaligned by 3072 bytes. this may result in very poor performance. repartitioning is suggested. -10gb ext 4, usage: file system, partition type: linux basic data partition, partition flags:--, type: EXT4(version1) label:--, device: /dev/sda9, partition label:--, capacity: 10 GB, available:--, mount point at / warning: the partition is misaligned by 1536 bytes. this may result in very poor performance. repartitioning is suggested. -478GB ext4, usage: filesystem, partition type: linux basic data partition, partition flags:--, type: EXT4, label:--, device: /dev/sda5, partition label:--, capacity: 478gb, available:--, mount point: mounted at /home warning: the partition is misaligned by 512 bytes. this may result in very poor performance. repartitioning is suggested. -2.0gb Swap 2.0Gb, usage: swap space, partition type: linux swap partitioin, partition flags:-, device: /dev/sda6, partition label: capacity: 2.0gb warning: the partition is misaligned by 512 bytes. this may result in very poor performance. repartitioning is suggested. and as you can see it is not well organized so please help me to organize the partitions witahout uninstalling the w7, and if possible the grub2

  • Would Windows 8 may increase the Cap of more than 2 GB?

    - by Pisaro
    I have a old Laptop Dell Latitude D430 that I just upgraded to Windows 8. The Ram that I have installed is 2GB (Max Ram that this laptop can handle) but I am wondering if by installing windows 8 can help also to increase the cap of the total Ram that the laptop can handle. I know that some laptops have a cap of RAM by the Bios but I am wondering if any of you know if by installing a new OS can actually change this? thanks, Robert

  • Find out how many memory my server would need ideally?

    - by Daniel
    I have a pretty busy GNU/Linux server that I think needs more RAM. I know that the free command doesn't show the amount of RAM that is used. So I was stumbling upon Commited_As in /proc/meminfo. It currently shows 57972 kB which isn't much. Is this the amount of RAM that the processes use "right now" or is this an estimate of how many additional RAM it would take to never run out of memory with this load?

  • IIM Calcutta &ndash; EPBM 14 &ndash; Campus Visit &ndash; Day 4 &ndash; Managing Self, SDCC and Gari

    - by Ram Shankar Yadav
    …I’m becoming more of an addict of writing about my experiences, here in Kolkata! Today we started a bit of late at around 8 AM, did our breakfast and reached in class a bit late at around 9:50 AM, and here goes the surprise…. Today we had two lectures on “Managing Self” and two lectures on “Sustainable Development and Climate Change” (SDCC). Some of us got few self discipline lessons the moment they entered class and asked to “get out” :D So frankly speaking it was a nostalgic moment, which reminded us of Collage ;) We did a FIRO-B test as and got very good tips on managing ourselves and differentiate between “manager” and “leader” After the lunch we had our session on SDCC, in which the prof started by explaining “Credit Crisis”, and moved on to Sustainable Development and few great examples from industry and life~! After the class we went for shopping at Garihat Market, we ate Pani Puri and Moodi :P ..one more surprise…my room got flooded with lot of my new ePBM friends to take the copy of the pictures and we did lot of chit chat around anything and everything :D …so far so good…it’s an amazing experience for me and hopefully for others….who came out of their daily chores and went back to the nostalgic lanes of friendship, learning and most importantly “Happyness” ~~~ Cheers, ram :) EPBM 14 pics : http://epbm14.shutterfly.com/pictures

  • IIM Calcutta &ndash; EPBM 14 &ndash; Campus Visit &ndash; Day 1 &ndash; Registration &amp; Beginning

    - by Ram Shankar Yadav
    Hey Guys! I’m back with the updates, it was an awesome Monday morning, for me it started when Sun came on my face, and the time was 5:30AM~~ I was amazed that this part of the country gets the sunrise quite early, but I ignored the sunlight for a while by covering my face, but…finally the door knocked….~ It was Mukesh, and the time was 6 AM, so I thought let’s get rid of laziness and start my day~ After having my brush and bath, I shaved and we headed for the Breakfast~ We quickly had our bread butter jam combo, and left for the Auditorium for Registration~ We searched for our names and signed the Registration paper and got a cool IIM C bag, with following in it: - a IIMC Notepad - Cello X Caliber pen - a book “What the Best MBAs Know”, and - Reading Material for Campus Sessions Today we had lectures on “Evolution of Indian Corporate Sector” (2 Session of 1.5 hrs each) and “Indian Economy: Crisis & Response” (2 Sessions of 1.5 hrs). “Evolution of Indian Corporate Sector” was by Prof. Raghabendra Chattopadhyay, was one of my best lectures I’ve ever attended in my life, he started with a question that saying that “The Indian Capitalists didn’t wanted the economy to open up till the economic reforms occurred?”, he is one of the best story tellers I’ve ever met, he started with the ancient European and Indian history and linked the trade & economics with it, simply amazing~ I can’t believe I didn’t get bore even after a 2hour long session…awesome~~ Afterward we had our lunch break, we did our lunch in “New Hostel” building and got back for “Indian Economy” sessions. Indian Economy session was taken by Sudip Chaudhuri, for us he’s a well known face as we have already attended his sessions on Macroeconomics~ It was an interactive, easy going, and a laughable session, and we did discussed some serious issues as well. After the class got over we went out and got few T-Shirts and Mugs for ourselves, and yep not to forget it “Rained” in Kolkata today~~ We got back and had our dinner and dispersed finally… I loved this amazing Monday, and hope the spirit continues till Saturday~ I’m feeling the enrichment in my thought and perceptions~ I’m lovin’ it~~ ram :)

  • IIM Calcutta &ndash; EPBM 14 &ndash; Campus Visit &ndash; Day 2 &ndash; IS_Strategy and Internationa

    - by Ram Shankar Yadav
    Hey Guys~ So the second day of the week starts, and we were all set for coming sessions on : - IS & Strategy and, - Changing Geo-politics & Business Environment We did our daily chores, rushed for breakfast, and reached Auditorioum, almost on time. IS & Strategy session was quite informative and interactive, and the prof. gave lot of examples, and it really gives us solid understanding by relating things with examples. Then goes the lunch, but the IS session over shoot for 15 minutes so our idea of taking a nap in lunch was not working out, but anyway we did our lunch and tried to sleep for 10-15 minutes. We got back and session on International Business started. Frankly, it’s a great topic, but we had tough time to be attentive, and it was hard to keep ourselves awake :P Anyhow the session came to an end, and we went to Library, and roamed around campus. Got back, had dinner, and went for a night walk, and ice-cream party. Lastly we did went to the platform inside the lake, and had a gag session, got back and  did “ITC eChaupal” case study. We have planned to visit Kali Mandir tomorrow, so I’ve to sleep for few hours…GN! Stay tuned for more… ram :)

    - by Ram Shankar Yadav
    Hey folks~ Today was one of the most happening day for us, we got up @ 5 AM and did our daily morning chores and left hostel room by 5:35 AM. So why we got up so early??? Okay we planned a visit to Kali Temple at KaliGhat! So till everyone assembles, we took few pics on the Lake Deck. We left Joka campus at 6 AM and reached Kali temple at 6:50 AM. Kali temple is very famous in Kolkata, but the frankly speaking it’s one of the most unorganised one for sure~! After darshan, we got back into our Taxis and headed for breakfast at Gupta Brothers Restaurant. We enjoyed “doodh-jalebi”, “Kachori-sabzi” and rasogullas there~! While coming back, one of our Taxi’s excel broken and we waited for the first to come back and take us to Campus. After coming back to campus, we attended our sessions on IS & Strategy on ITC eChaupal and Transactional Cost and Vertical Integration(TCVI). After our classed we had “Dinner Party” organised by IIMC, and we enjoyed it thoroughly, and many of us took this as an opportunity to share our biz card and talk to Professors. Overall it’s was a rocking day!! Stay tuned for more… Cheers, ram :)   Photo Album :

  • Single Responsibility Principle usage how can i call sub method correctly?

  • ASP.NET - What is the best way to block the application usage?

    - by Tufo
    Our clients must pay a monthly Fee... if they don't, what is the best way to block the asp.net software usage? Note: The application runs on the client own server, its not a SaaS app... My ideas are: Idea: Host a Web Service on the internet that the application will use to know if the client can use the software. Issue 1 - What happen if the client internet fails? Or the data center fails? Possible Answer: Make each web service access to send a key that is valid for 7 or 15 days, so each web service consult will enable the software to run more 7 or 15 days, this way the application will only be locked after 7 or 15 days without consulting our web servicee. Issue 2 - And if the client don't have or don't want to enable internet access to the application? Idea 2: Send a key monthly to the client. Issue - How to make a offline key? Possible Answer: Generate a Hash using the "limit" date, so each login try on software will compare the today hash with the key? Issue 2 - Where to store the key? Possible Answer: Database (not good, too easy to change), text file, registry, code file, assembly... Any opinion will be very appreciated!

  • How to keep the CPU usage down while running an SDL program?

    - by budwiser
    I've done a very basic window with SDL and want to keep it running until I press the X on window. #include "SDL.h" const int SCREEN_WIDTH = 640; const int SCREEN_HEIGHT = 480; int main(int argc, char **argv) { SDL_Init( SDL_INIT_VIDEO ); SDL_Surface* screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, 0, SDL_HWSURFACE | SDL_DOUBLEBUF ); SDL_WM_SetCaption( "SDL Test", 0 ); SDL_Event event; bool quit = false; while (quit != false) { if (SDL_PollEvent(&event)) { if (event.type == SDL_QUIT) { quit = true; } } SDL_Delay(80); } SDL_Quit(); return 0; } I tried adding SDL_Delay() at the end of the while-clause and it worked quite well. However, 80 ms seemed to be the highest value I could use to keep the program running smoothly and even then the CPU usage is about 15-20%. Is this the best way to do this and do I have to just live with the fact that it eats this much CPU already on this point?

  • Can I monitor a service's memory/cpu usage on OpenSolaris?

    - by Phillip Oldham
    What would be the best way to monitor a service's memory/load on the OpenSolaris platform so that one can send alerts and automate service management (restarts, etc) based on "rules"? On the linux platform I use Monit, but since OpenSolaris has SMF I thought there may be a complimentary service "built-in" if SMF doesn't have those features and I'd prefer to use a standard OpenSolaris app if there is one.

  • How can I limit my data usage over tethering on Windows?

    - by Casebash
    The excess data charges if I go over my tethering data limit are ridiculously. Fennec already stated the question well. Because of this, and on general principle, I'd like to have some tools which permit me to do things like: Monitor the amount of bandwidth that I've used I think I can do this from Sprint too, but on-the-computer is nice too on-the-computer gives me a possibility of breaking it down by application See what sort of programs are using the Internet connection I could use, like, Wireshark, but that's a bit too micro-level to be practical Keep those programs, and the operating system, from doing things like "downloading an operating system update" while on the mobile hotspot Related I want to monitor and limit OS X's data transfer while I'm tethering via my iPhone

  • Should websites live in /var/ or /usr/ according to recommended usage?

    - by nbolton
    According to a guide on the Linux directory structure, /usr/ is for application files, and /var/ is for files that change (I assume this means "files that belong to the applications"). Is this correct? If this is the case then I'm a little torn between using either. A website is an application (if it's dynamic, so to speak), but in other cases it is just a collection of files used by Apache. The default www dir lives in /var/www/, so should we follow suit by using /var/websites/ (or something similar), or choose /usr/websites/ since they could be applications? This is a very trivial question, but it's bugging me nonetheless. For our case, I'm leaning toward /usr/web or something like that, since our websites are all applications. Update: This is for our company websites; it's not a shared hosting server, so we don't need to worry about separating them in /home/ or anything like that.

  • Laptop burned after heavy OpenGL usage. Is there hope?

    - by leladax
    After programming for OpenGL and a 'slow OS' case for a couple of minutes the screen went blank. I shut it down with forcing it with the shutdown key and now there's no led at all with battery or AC, it doesn't start at all, it's totally dead. It's most certainly not the AC adapter since that didn't show at first, it doesn't start a led at all and if the AC is connected it does a very slight and faint clicking noise (one has to have his ear next to it to hear it, near the AC connector). Is there any hope? I suppose it's a burned motherboard. I suspected a burned GPU but that would still leave the leds at least lid or at least attempting to start up. Now it's totally dead. It's a TOSHIBA satellite x200-219. It has no warranty, as it's more than 2 years since purchase.

  • How can I get a data usage/access log for an external hard-drive?

    - by Vittorio Vittori
    Hello, I'm working in an office with many people and sometimes I leave my external hard drive with my personal data inside. I would to know if there is some way to see if my hard disk was used during my absence. I'm not the computer administrator, so I can't use exclusive file permissions and I would really like to know hard disk is opened from another computer. I am using a Mac. Does exist some other way to protect personal data on usb device like an hard-drive? If yes can you write some link to possible guides? I hope there is some ploy!!

  • Reseting Macbook Pro keyboard and trackpad's power usage on Windows?

    - by Dan the Man
    I recently installed a utitlity for Windows (ASUS Ai Charger) which modifies the USB ports on the computer to output more power (for charging iPads, etc). The problem is, I believe it is also giving more power to my keyboard and trackpad. And now, neither devices are working at all, yet they work on Mac OS X. So does anyone know the amount of power MacBook Pro (2007) keyboards and trackpads use, and how I can set these settings in Windows 7?

  • Collecting and viewing statistical data on website usage? Want to give Google Analytics the boot.

    - by amn
    I have always been somewhat reluctant to "outsource" site statistics to Google. We have an Apache server running on a Windows server. I am pretty sure all the foundation to collect the needed visitor data are there. I would like to stop using GA, and use some form of application where the data does not travel to a third party but remains at the host, or at least travels to the remote administrator, if it is a log analyzer in a browser. What are my options?

  • Are some DSL modems cheaper to operate than others? (power usage question)

    - by SetJmp
    I recently have started using a Motorola 2210 in conjunction with AT&T's DSL service in the Silicon Valley area. That gadget runs hot to the touch! Which means... I assume it is gobbling lots of electricity even when I am not using it. Has anyone studied this subject in a rigorous way? Which leads to the question... if the 2210 is very energy inefficient are some DSL modem models cheaper to operate than others? -SetJmp

  • How can I compare effective power usage of two CPUs / CPU+Mobo+Mem combinations?

    - by einpoklum
    I have this server which does mostly file sharing (with the associated storage). No serious number crunching and it isn't the firewall. My current box has a Celeron D processor (Prescott 336 2.8 GHz); and I'm considering replacing it with a Pentium D (Smithfield 805 2.66 GHz) - for reasons which do not involve performance. How can I know whether one can expect a higher or lower power consumptipn for the change? And how can I estimate the power consumption for each option?

  • How to calculate required switch speed based on network usage?

    - by tobefound
    I have a 48 port HP Procurve Switch 2610 (J9088A) that can handle 13.0 million PPS (packets per second) and features wire speed switching capacity at 17.6Gbps. First off, what does that REALLY mean? Where do I start when trying to figure out if my office (with 70 employees) will be well setup with this switch? How to calculate through-put based on a user average load of X MB per day? 90% of the folks will only be sending email, access random websites, etc... the other 10% will be conducting heavier tasks like moving image files (10 MB) across network shares, constant external FTP streams through the switch to a server etc... Is this switch good enough?

  • Startech SVx41HDI Series Server Remote Control Usage Question - How do I switch away from a dead por

    - by tajh
    We have a Startech KVM over IP model SV841HDI and it was stuck pointing a port where the machine has been removed. We ended up having to physically plug something into that port in order to switch ports again, meaning that if someone in support accidentally switches to an empty port, we need to have a documented solution for making it useable again. The unit is old, no longer under warranty, firmware updates for it are no longer available (interestingly it runs a powerPC version of busybox). Since it does work well except for this one catch, we would like to avoid replacing it. Reading the manual, you have a several recommended methods. I tried them. Hit the left CTRL key a few times (as well as all the other popular KVM keys I could think of). The VNC GUI offers lots of buttons - none of them switch away from a dead port. The question is: how do I switch away from a dead port on this particular KVM remotely?

  • Does Intel Smart Response provide any statistics on the cache usage?

    - by Tom Seddon
    I've set up my Z68-based Core i7 PC with a 60GB SSD dedicated as a Smart Response cache drive. Is there any way I can get any statistics out of it? It would be nice to have some information on how much cache space is actually being used, maybe how much of it was actually accessed recently, and how many reads in general are coming from the SSD rather than from the mechanical disk. These statistics might help to quickly provide some evidence for or against the use of Smart Response, without my having to reinstall Windows on the SSD (etc.) to find out. The Windows ReadyBoost feature has some performance counters you can access via the Windows 7 perfmon tool, for example, which is the kind of thing I'm hoping is somehow available. Smart Response provides no perfmon counters, though, and the Intel Rapid Storage Utility tells you pretty much nothing except that Smart Response is switched on.

  • How to restrict Windows 7 internet data usage while using mobile connection?

    - by Daniel Gehriger
    When I'm travelling I would like to use my iPhone's mobile hotspot feature to provide Internet access for my Windows 7 laptop. However, my mobile data plan has a limit on the amount of data I can use per month, and I would like to restrict Internet access to a few very specific applications (such as a database administration tool and Chrome). Is it possible to create a firewall profile for use with mobile data access? If not, what tools exist that could assist me?
