• Any recommendations on a NAS for a home-super-user?

  - by marc_s

  Can anyone recommend a good NAS for use in a home-server environment? I would request at least 2, preferably 4 disks, and I am most interested in good to excellent throughput for file-server and backup purposes - don't need any of the fancy media-streaming or -sharing features, that's not of interest to me. For a 4 or more disk solution, support for the various RAID levels (0, 1, 1+0, 5) would be a plus - especially if supported in hardware (rather than just a software emulation). I just need a place to put my collection of data, ISO images, and so forth - and since several external disks (self-built and off-the-shelf) have failed so far, I'm looking into a more reliable solution.

• excel autocomplete combo-box with on-selection event

  - by IttayD

  Hi, I have an excel sheet for groceries. One column is the name, another is whether to buy it or not (checkbox) and another is the amount. I'd like to have a widget in the top row so that I start typing an item's name and it shows a list of matching items that I can select from, or if I continue to type and there's only one item, completes its name. When the last item is selected, other widgets show the amount, which I can edit and clicking 'check' will check the item in the list. I know this is kind of very specific, but am hoping someone can at least get me started. Thank you, Ittay

• large RAID 10 vs small RAID1

  - by user116399

  The machine will store and serve millions of small files (<15Kb each), and all those files require a total storage space of 400G Considering the exact same SATA hard drives maker and models, on the exact same environment (OS, cpu, ram, raid controller, etc...) which one of the setups bellow would be faster? A) RAID 1 with 2 drives of 2T each, making up total storage of 2T B) RAID 10 with 4 drives of 2T each, making up total storage of 4T [EDIT]: I'm aware RAID10 is faster than RAID1. The larger the disk, at least in theory, the longer will take to do seeks/writes. So, will the performance gain of RAID10 will be outweighed by the "drag" caused the larger disk area when seek/write operations happened?

• Windows 7, how to get unlock (Press Ctrl+Alt+del) prompt on all monitors?

  - by Zugwalt

  I have a laptop that I keep shut in a docking station as I have two screens connected to the laptop and it cannot display to both of those AND its own screen. However, when my computer locks by itself (Not when I lock it using Ctrl+Alt+Del) the login prompt is ONLY on it screen (at least its there when I open it up) and my primary external monitor is off and my other one is all black. This means to log in I have to hit Ctrl+Alt+Del and blindly enter my password--which I don't mind too much, but would prefer if I could actually see the unlock/login prompt instead of typing on a black screen. Any way to have it show the login prompt on all monitors?

• Password protected traffic meter

  - by UncleBob

  Hi first, I have a small problem for which I haven't found a solution yet. I live in Bosnia and share the Internet connection with the landlady, and as is usual in Bosnia, we do not have a flat rate, but a 15 Giga traffic limite. That would actually be more than enough, if the son of the landlady wouldn't be watching videos all the time, so the bills are truning out rather expensive. I have already installed a traffic monitoring program, but he apparently turns it off as soon as he comes close to his limit and then denies that he consumed any more. I therefore need at least a measurement program that is password protected and / or notes in the log when it's been turned off. Even better would be a program that just cuts his access when he exceeds his share, ie a mixture of Traffic meter and Parental Guard. Can someone help me out here?

• Win Server 2008 R2 - Mapped shared folder hanging?

  - by M-Tech

  I have recently built a windows 2008 server R2 machine. This is purely for file server purposes and is very much a basic build. All windows updates installed and part of domain. I have setup a shared folder on the C:Drive and added permissions for domain users as co-owners. The client machines run XP SP3 and are part of the domain also. We have a few servers running the same setups on a few of our sites but this one is particular crashes users machines (explorer.exe hangs for at least a few mins) when attempting to access the shared folder. I have turned off the option on the network card for power save aswell still no change. Any help with this is very much appreciated and i look forward to hearing from you ;)

• Safari 7 SSL error if using IP-adress

  - by K. Biermann

  I have created my own CA for internal usage and set the root certificate to trustworthy on my machines. With this CA I signed the SSL-certificates for my internal servers. I only address them with their IP and so I used the servers' IP as certificate name. If i connect to the Servers with Chrome or mobile Safari it works without problems, but if I use Safari 7 under Mavericks (on the same machine with the same keychain) i get the following error: "The certificate is not valid (host name mismatch)". I double checked that I entered the correct IP ("https://192.168.2.130"), but I always get the same error. Do I need to enter a different name for the certificate or is it just that Safari doesn't support SSL certificates for IPs? Here is a screenshot of the error message (I can only post images with at least 10 rep): Safari's error message Thanks in advantage and please excuse my bad English :D

• GVim asks for passphrase on every action when using scp

  - by Ashnur

  I want to use my vim config when editing files, but there are at least 5 different servers right now where I have to edit them. Of course I could use console (where I set up ssh-keys and and have a script so it wont asks for passhphrase), but then I have to maintain the vim config on every machine. so I decided to use gvim and browse/edit the remote machines via scp://, but on every action a popup appears asking for the passphrase. this is a ubuntu 10.10 install, with xfce installed later on. i checked in the xfce settings so gnome services should start, but it still won't remember the passphrase.

• Exchange 2010 and DAG - all roles on both servers?

  - by Keith

  We just recently migrated to an Exchange 2010 server. Currently all of the roles and mailboxes are installed on 1 server (we are a small company with less than 100 users). I am wanting to use DAG for replication however it seems most set ups for DAG requires at least 3 or 4 total servers. Is there anyway to make this work with just two servers and both of these servers would have all the roles and mailboxes? Maybe there is a better way to do this than DAG? I'm open for suggestions. The goal here is to have some sort of replicated server so that if there is an issue with our primary Exchange server, another one can be brought up within an hour or so with all current information (not a backup). It doesn't necessarily have to be instantaneous.

• How SSD's drives reduce their latency?

  - by tigrou

  First time i read some information about SSD's, i was surprised to learn they internally use NAND flash chips. This kind of memory is generally slow (low bandwidth) and have high latency while SSD's are just the opposite. But here is how it works : SSD drives increase their bandwidth by using several NAND flash chips in parallel. In other words, they do some data striping (aka RAID0) across several chips (done by the controller). What i don't understand is how SSD's drives managed to reduce latency? (or at least lot better than what a single NAND chip without any controller can do)

• Easy way to reload multiple applications under a single IIS Website after AppPool Recycle?

  - by MadBurn

  I'm not sure where to begin or even if my thinking is in the right direction. Hopefully someone here can tell me what to do or at least give me a direction to start travelling. I work on a Intranet Website, that contains multiple MVC3 and Coldfusion Applications. I have set the AppPool to Recycle every morning at 2:00 AM. Now, I would like to create a Scheduled Task to reload every application contained under that IIS Website so that when the first user comes in in the morning, they don't have to wait 30 seconds to 2minutes for their application to be reloaded into the IIS AppPool. Is there an easy to to do this? As I see it my only options are: Writing a bash script, inserting each website manually to load Writing a program that would try to find every application and load them Now, if there those are my only options, is there possibly a .NET Library I can tap into that would allow me to easily find the MVC3 Applications under IIS?

• How to force Windows XP to rename a file with a special character?

  - by codeLes

  I have a song that Windows can't play because there is a question mark in the name of the file. "Where Have All the Cowboys Gone?.ogg" // as an example So I try to rename it and Windows complains whether I try it in Explorer or from command prompt. Error I get when trying to copy, rename, or move is: The Filename, directory name, or volume label syntax is incorrect Is there a Windows way to force a rename in this case? Update I'll keep an eye on this question, but after 13 answers and many attempts (aside form 3rd party solutions) it seems that Windows can't do this (or at least my windows can't, no short names). So I'm accepting the answer which was my original solution anyway of using Linux. It would be nice to see Windows handle this somehow, so don't stop just because I've accepted this answer, the question still stands!

• crontab still sending emails even with > /dev/null

  - by user2344668

  I have a crontab (root) that runs a script and output is set to /dev/null but I always get the emails whenever it runs. I only want to receive error emails. # Rackspace driveclient update (12pm MST) 0 12 * * * /root/scripts/driveclient-update > /dev/null The only way I can get it to turn off is to use /dev/null 2&1 but then I won't get error emails. This is happening on three different CentOS servers, two are 6.3 and one is 6.4. NOTE: I have read over and over that /dev/null is supposed to send stdout there and prevent the email if there is nothing but stdout from the script, so at works for at least some people; I cannot figure out why it is not working on these servers. Here's an example of where /dev/null is supposed to work: http://www.alphadevx.com/a/384-Suppressing-Cron-Job-Email-Notifications

• Can't access to access to my web server inside a network with Firewall on

  - by ianenri

  I set up a Web server with the following: There is the Internet Router, configured to Port Foward port 80 to my computer assigned to my PC's IP: 192.168.1.128 My PC is connected to that wireless router from wlan0 Then, my PC is also connected to my device (which is the webserver) with a crossover-cable usign eth0 having this anohter IP: 10.42.43.1 Finally, my device (the webserver) is connected with eth0 with this IP: 10.42.43.55 As you can see, I need to install a reverse-proxy to be able to resolve to my device's webserver. I installed pound (proxy server) in my PC and configured properly to make 192.168.1.128 resolve to 10.42.43.55 So, I just typing my ISP provided IP 200.x.x.x resolves to my device webserver. But there's a problem: I HAD TO STOP MY FIREWALL. I don't know how I need exactly configure the firewall in SUSE YAST2, or at least iptables. Stopping it is not an option, not for security reasons, just because there's port fowarding rule that is needed to give Internet access to my device too. I'm using openSUSE 12.1

• How to explain DRM cannot work?

  - by jerryjvl

  I am looking for the shortest comprehensive way to explain to people that are trying to use DRM as a technology to prevent users from using their data in some fashion deemed undesirable, why their solution cannot work by definition. Ideally I'd like something that: Covers why technically it is impossible to have people access local data, but only in such-and-such a way Imparts an understanding of why this is, to avoid follow-on "But what if" rebuttals Is intuitive enough and short enough that even a politician (j/k) could grasp it When faced with this situation I try to be clear and concise, but I usually end up failing at least on one of these points. I'd really like to have a 'stock' answer that I can use in the future.

• Starting scheduled task by detecting connection of USB drive

  - by gemisigo

  I know it has been discussed before several times that it is not possible to start an application from an usb drive when connecting it due to limitations of autorun (or autoplay??) in Win 7. But it is possible to create a scheduled task having On an event type trigger and surely there must be an event occurring when the drive is connected. Does anybody have the slightest idea which Event ID should I use? Or at least what type of event? There are too many logs to pick from.

• Force Windows 8 Metro apps to run lower resolutions below 1024x768?

  - by piokuc

  I have installed Windows 8 Consumer Preview on my Samsung NB30 netbook. I was very excited to try it on this little box cause it has a touchscreen and Windows 8 is supposed to be optimized for touchscreen devices. The installation was quick and smooth and all the drivers seem to work well including the one for the touchscreen. There is one major problem, though: when I try to tap one of the tiles on the Metro UI it displays This app can't open. The screen resolution is too low for this app to run. The machine has Intel Atom N450 processor and Intel GMA 3159 integrated graphics card and has maximum resolution 1024x600. I've read that Metro requires at least 1024x768. Is there a solution to this problem? Is there a way to force Windows 8 Metro apps to run in lower resolutions?

• Proxy Server suggestions

  - by Jon Menefee

  Here is the question I have that hopefully is not too general of a question. I have a network with approximately 25 PC's, 3 servers and 25 IP cameras. I have a firewall already on the network and it works fine for what I need, but my client is asking me if there is a way to put a Proxy server on the network to monitor where his employees are going when they surf the Internet. He is not wanting to block them (at least not thru the Proxy server), but he wants to make sure that they arent going to sites that would compromise the networked PCs. I have looked at TMG and it is a little more than what I want. I hesitate adding another firewall to the system because of the security cameras that are presently on the network (IP Cameras). I just want to put a policy in AD that would make certain Users (or Computers) use a Proxy server. Any suggestions on a good proxy server are welcome. Thank you

• My hard disk does't get recognized

  - by SteveL

  For a few days now I have a problem with my 500GB internal hard disk. I am on Linux Mint 13 but I have the same problem with my Windows installation. When running fdisk -l I can see my hard disk (same on BIOS) but I can't mount it even via the disk utility program. In Windows XP I can see it on the My Computer menu but when I click it, it say's: D:\ is not accessible The file or directory is corrupted and unreadable Is there a way to fix it? Or at least save some of my files and format it? Should I be thinking about the worst-case scenario e.g. my HDD is dead? Edit: The filesystem is NTFS.

• Extract duplicity difftar files manually

  - by isnogud

  I have a duplicity backup which i am not able to recover with duplicity. By calling duplicity file:///path/to/backups /path/to/dir, it returns "Local and Remote metadata are syncronized, no sync needed." but the /path/to/dir is empty. I decrypted all backup volumes and I'm able to view and extract the files from the different difftar files. My only problem is that there are files partitioned and saved in folders named after the files. Can anyone give me a simple script or at least a hint how to untar these difftar files so i get the actual files instead of the partitioned ones?

• Restore Point area getting deleted

  - by PaoloFCantoni

  Hi, I'm running a multi-boot scenario (which I have been successfully on a number of machines for a number of years). I have Windows 7 (32 bit) on one partition and Windows 7 (64 bit) on another and a common data partition (which happens to store the user hives for each OS instance). For some reason, on one particular machine (a HP Pavilion notebook) the restore points get trashed after a reboot. I can create them (both manually and automatically), but after some (but not all) reboots the restore points get trashed. I have all three partitions set (on both OSs) to hold restore information. This setup has worked successfully on other machines for at least 12 months. I'm out of ideas... I DO need the restore points as I do "bleeding edge" stuff and they've saved my bacon on other machines in the past... TIA, Paolo

• Incremental search for un/accented characters

  - by user38983

  Does emacs have an incremental search mode, where searching for a character will search for itself and for any other versions of the character with accent marks, similar to how Google Chrome (at least v27) will do when searching in a page? Alternatively, is there an additional library or piece of elisp code that can put incremental search in such a mode? For example, incremental search for: 'manana', would find 'manana' or 'mañana' 'motley crue', would also find 'Mötley Crüe' (with case-sensitivity off). Even a solution that only covers a subset of these characters would be helpful.

• What happened to QuickTime Pro for Windows editing features?

  - by Tod

  I used to record screencasts in SnagIt and then edit them in QuickTime Pro on windows with no problem. I haven't done it in a few months and now when I try most of the editing features have gone whack-a-doodle. For instance, if I got to delete a few seconds of video, it actually ends up deleting 20 seconds of video. I have repeated this on various source files including the Sample.mov that comes with QT. Using Edit-Cut looks like it works, but it doesn't actually do anything. Trim still works but that appears to be it. I know at least one other person has confirmed this behaviour. Does anyone have any work arounds. I'm using Windows 7 64 bit. QT Info QT Pro 7.7.1 (1680.42) QuickTime Version 7.6.8 (1675)

• When using RAID10 + BBWC why is it better to separate PostgreSQL data files from OS and transaction logs than to keep them all on the same array?

  - by Vlad

  I've seen the advice everywhere (including here and here): keep your OS partition, DB data files and DB transaction logs on separate discs/arrays. The general recommendation is to use RAID1 for OS, RAID10 for data (or RAID5 if load is very read-biased) and RAID1 for transaction logs. However, considering that you will need at least 6 or 8 drives to build this setup, wouldn't a RAID10 over 6-8 drives with BBWC perform better? What if the drives are SSDs? I'm talking here about internal server drives, not SAN.

• proxy server software for windows xp

  - by This is it

  Hi Is there a proxy software for Windows XP that can support HTTP, HTTPS, SMTP, IMAP, POP, FTP, etc. (the more the better)? We tried apache mod_proxy but FTP doesn't work through it (at least not all features). Maybe we don't need proxy server for following requirements (we are open for suggestions): - Centralized access point to internet for several users (proxy server?) - Users use Browser (firefox/IE - HTTP, HTTPS), Outlook (SMTP, POP, IMAP) - Logs to see where did users go on internet - Possiblity to connect to FTP server Windows xp, which is used as proxy server, is a virtual machine, and all other users/clients are virtual machines as well (Hyper-V)... Thanks for suggestions. Cheers
