  • Does vertical position affect hard drive?

    - by yoosiba
    Hey. Recently I noticed that for many small PC cases hard drives are installed in vertical position while in midi tower and all bigger they are in horizontal position. What impact on hdd (non SSD, just plain hdd with all mechanical parts inside) has vertical position/ Does it decrease life of hdd? Is it more prone to data errors?

  • Which service should I make mine dependant on ?

    - by Retrocoder
    I want to add a dependency to my service so that it only tries to start after most of the Windows services have started. Can anyone recommend such a service that is unlikely to have been disabled for security reasons on corporate sites. As my service needs the networking services up and running I want to make sure mine starts after these. This service may also be deployed in non-corporate environments so I’m looking for a suitable service that is unlikely to have been disabled by the end user.

  • How to install SSL on current site?

    - by vpoola88
    So I've looked at a ton of guides, but non of them seem to get our site to work. This is what I was probably following the closest:https://www.digitalocean.com/community/articles/how-to-create-a-ssl-certificate-on-apache-for-ubuntu-12-04 I also wanted to know why there is a default-ssl in apache2/sites-available ? Is this where I would have to put my configuration? This is my first exposure to SSL and site deployment in general. Thanks guys.

  • CNAME to another domain fails on some office networks, why?

    - by crashalpha
    Our domain "aspenfasteners.com" is hosted by Volusion. We have CNAME records "find" and "search" which point to site indexing accounts on www.picosearch.com. These addresses fail on SOME private office networks which have their own DNS. We suspect the problem comes from Volusion's own name servers, n2.volusion.com and n3.volusion.com. Volusion support on problems this technical is non-existant. We have tried an NSLOOKUP on find.aspenfasteners.com with level 2 debugging info, and we got the results below. Is it possible that the local DNS is recursing to Volusion's name servers, and that while Volusion DOES return the canonical name, they do NOT resolve the address? Can anybody with expertise in this sort of stuff PLEASE look at the NSLOOKUP below and tell me if we are right, because Volusion is giving me absolutely NO support on this topic. I need proof of where the problem lies. Thanks VERY much!

  • Where to find a list of bad passwords?

    - by Steve Morgan
    I need to implement a 'stop list' to prevent users selecting common passwords in a new online service. Can anyone point me to such a list online anywhere? Edited: Note that I'm only trying to eliminate the most common passwords, not an exhaustive dictionary. And, of course, this complements a reasonably strong password policy (length, use of non-alpha characters, etc.) Thanks.

  • Why is pdf format used?

    I will admit that I am new to the tech/dev field. It seems to become a trend that every time I have to work with pdfs a part of me dies. Why is this format as ubiquitous as it seems to be? Is it just non-tech people that prefer pdfs?

  • convert full-disk RAID5 array to partition-based array?

    - by Delan Azabani
    I have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care). Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?

  • Is there a way to set windows 2008 file and folder sharing permission so you only get prompted for a

    - by Matt
    Is there a way to set windows 2008 file and folder sharing permission so you only get prompted for a password on certain shares? That is, right now, when I got to \theserver\ I get prompted for a password despite having some shared folders that permit anonymous access. Is there a way, asides from setting the policy sharing model to guest rather than Classic to allow a user from a non-domain pc to go to \theserver\ and see the shares and permit him or her to enter a folder with anonymous access without having to enter a username or password?

  • Forcing tar to create an empty archive

    - by snostorm
    I'm trying to use tar to tar files before transfer, so I can keep the entire file path rather than losing it along the way. However, when I try to tar an empty folder, it tells me that it is cowardly refusing to create an empty archive. I want to keep the empty folder on the other end, but don't want to put anything else into the archive to make it non-empty. Is there any way to do this?

    Hello, is it possible to remove a user's password using the net command? I tried "net user *" and just hitting return twice, but this does not work as expected. Is there any other way to do this? (I'd gladly take non-net commands, as long as they are built-in in XP SP3) Best regards, MB

  • using gmail as email relay for sendmail

    - by Nikita
    I used to be able to send emails using a gmail account & sendmail configured using one of the guides on the Internet, for example: http://appgirl.net/blog/configuring-sendmail-to-relay-through-gmail-smtp/ This is a small server and I've recently moved it to a different house. And sendmail has stop working. The only thing different in the network setup is a new router. What is happening: In the log files, I see the following error: ...stat=Deferred: smtp.gmail.com: No route to host When I run from the command line: strace sendmail -f A -t B -u "Subject" -m "Message" -tls=yes ssl=yes -s smtp.gmail.com:587 -xu A -xp XYZ It hangs on this call: recvfrom(3, "m0\201\203\0\1\0\0\0\0\0\0\4ares\3lan\0\0\34\0\1", 8192, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.1.254")}, [16]) = 26 close(3) = 0 time(NULL) = 1339997943 open("/etc/localtime", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=3477, ...}) = 0 fstat64(3, {st_mode=S_IFREG|0644, st_size=3477, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb76ff000 read(3, "TZif2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\4\0\0\0\4\0\0\0\0"..., 4096) = 3477 _llseek(3, -24, [3453], SEEK_CUR) = 0 read(3, "\nEST5EDT,M3.2.0,M11.1.0\n", 4096) = 24 close(3) = 0 munmap(0xb76ff000, 4096) = 0 socket(PF_FILE, SOCK_DGRAM|SOCK_CLOEXEC, 0) = 3 connect(3, {sa_family=AF_FILE, path="/dev/log"}, 110) = 0 send(3, "<18>Jun 18 01:39:03 sendmail[268"..., 96, MSG_NOSIGNAL) = 96 nanosleep({60, 0}, So it looks like at some point it tries to resolve the DNS name, but I don't have anything running on 53, so it dies out and then just hangs. The other interesting thing is that msmtp works just fine on the same server. Update: ares in strace output is actually the name of my server, but .254 IP address is the address of the router. Could anyone tell me why this is happening or what further steps can I take to investigate the issue? Thanks!

  • Turn off QuickTime 'start page'

How do I turn this off? I just want it to open the blank player, ready for me to play a file etc and not connect to the internet.

  • What is the simplest (free) way to change page numbers on a pdf?

    Hi Folks, I have a pdf document I created through non-Acrobat means (printing to pdf, then merging a bunch of pdfs), but I'd like to manually change the page numbers (i.e. the first several pages are simply title pages, "page 1" is really the 7th page of the pdf). What's the simplest (and ideally, free) way to do this? For what it's worth, I'm on Windows, though I have access to Macs as well. Thanks, /YGA

  • Setting charging limit on MBP?

    - by Giannis
    Is it possible to tweak settings so that the battery will only charge up to 90% -95% and then use power adapter to run ? A friend told me he was able to set such limits on his non-mac PC so I was hoping there would be a way to do it. From reading I have done online it appears this is better than having a 100% battery most of the time. I have an MBP 13" 2012 running latest version of OSX ML(10.8.2).

  • Some questions regarding Hostname

    - by user481913
    I just bought a new VPS hosting plan and i have a few questions. Hope someone here can clear the doubts for me. 1) Is it necessary to have a real domain for a vps hostname? I suppose i can just use a non-real domain like anydomain.com and something like 'server' for the computer name. Therefore i'll end up with something like server.anydomain.com as the vps's hostname. I want to do this for the sake of putting in a hostname to configure the vps to get it going . So, since this non-real domain name does not need to be publicly accessible i don't need to register or own it and instead access the server by the ip address. Is that correct? But i suppose that this also depends upon if my web host allows that? 2)I would also like to run some real sites with real domain names on this vps, so can i just configure the zone file on the primary nameserver and make entries for these domains and point an A record at the Vps's IP to make them publicly accessible over the internet? For example for my 1st domain i could make an entry like this: $TTL 86400 mydomain1.com. IN SOA ns1.mywebhost.com. \ admin.mydomain1.com. ( 2004011522 ; Serial no., based on date 21600 ; Refresh after 6 hours 3600 ; Retry after 1 hour 604800 ; Expire after 7 days 3600 ; Minimum TTL of 1 hour ) server IN A 200._._._ ns1.mywebhost.com. IN A 216._._._ ns2.mywebhost.com. IN A 205._._._ @ IN NS ns1.mywebhost.com. @ IN NS ns2.mywebhost.com. @ IN MX 10 server www IN CNAME server server IN CNAME @ (so this particular line tells the nameserver to point the url mydomain1.com to server.anydomain.com at the particular ip addresss in the A record.... is that right?) Similarly for my 2nd domain i could have a similar entry : $TTL 86400 mydomain2.com. IN SOA ns1.mywebhost.com. \ admin.mydomain2.com. (..... ............................so on........ ......................................... ......................................... ......................................... ......................................... ......................................... Is that correct? 3) Suppose for my vps hostname, i ignorantly chose a domain that someone else alreadys owns , however i think that it won't affect the public accessibility of the real domain or website since only the real owner of the domain has the rights to provide for the nameservers addresses in the TLD registeries through his Domian Registerar? Is that correct? 4)Can i change my vps's hostname later? Would this create any complications?

  • Getting custom web.config sections and their contents in Powershell
