  • Mimicking Google's Persistant Disks -- Is this a logical FreeBSD disaster recovery strategy?

    - by Casey Jordan
    I am looking into FreeBSD to provide a more comprehensive backup and disaster recovery strategy for database servers. Ideally I want to mimic what google is doing with "Persistant disks" https://developers.google.com/compute/docs/disks#snapshots I am hoping someone who knows more about FreeBSD can validate these ideas/questions: I have read that FreeBSD can take instant disk snapshots, therefore if our databases trigger a consistent state (Block all writes, and flush buffers to disk), I would assume I could take snapshots every hour without service interruption for more than a few seconds. Is this true? Is there a way to take snapshots and back them up offsite easily? Can this be done incrementally as to save how much disk space is actually used? If a rollback needed to be done, how long does this typically take? Is a rollback also instantaneous? Thanks!

  • Options not available anymore in my Samsung 932bw lcd

    - by Sávio Mendes
    I think a friend messed up something in my monitor. I left him playing a game and when i came back, i noticed that the brightness was very high. I tried to change it but i couldn't, brithness, contrast, color warm and a few other options are marked as "not available" (he probably adjusted the brightness and changed something else too, that it's causing this thing). I updated the monitor driver, the vcard driver, plugged the monitor in other pc (I'm connected through dvi, but in the other pc i plugged through rgb) but nothing fixed it. Is there someway to force reset all the options or something like that to fix this? (I'm running Win7 RC1 but I don't think that it has something to do with it, it was working perfectly until he messed it up, and the other pc where I plugged it, runs winxp and the problem occurs too. And it doens't look like a the monitor is broken, it works like it always did, just these options are marked "not available" now...)

  • How setup federated SQL data to display limited information to a Web server in the DMZ?

    - by Pcav
    I have a SQL server behind a firewall. I need to push some limited SQL 2005 information to a Web Server in the DMZ so that I do not have to let database queries come all the way into the database server on our internal network. I want to push a small amount of dynamic data to a Web server in the DMZ and lock it down so that our hosted website does not need to come into the internal network for information; I want to put a server in the DMZ that will be the only connection allowed to the SQL database. This DMZ server will be the only server that can have any sort of connection to the back-end database so the hosting provider just pull the data from our server in the DMZ...

  • Third monitor randomly defaults to 640 x 480 on startup

    - by ajbdev
    I purchased a PowerColor HD 5770 video card so I could get a third monitor working. I have two widescreen monitors, one attached via HDMI and the other attached via DVI. My third monitor is attached from DisplayPort to VGA (using a passive connector like this one) The third monitor is a 19" Hyundai L90D. I was unable to find any Windows 7 (or Vista for that matter) drivers for the monitor, so it's stuck with "Generic Non-PNP Monitor". It's native resolution is 1280 x 1024. Randomly Windows will boot up in the correct native res, but sometimes it boots up in 640 x 480 res. When it does boot up into 640 x 480 res, the screen resolution slider is stuck and I cannot slide it back to 1280 x 1024. I cannot find a pattern for when or why it will do this, I've tried rebooting five or six times in a row at times to get it to boot into native res, but this doesn't always work.

  • SQL Server database constantly restarting

    - by Michael Itzoe
    We have SQL Server 2008 Express installed on a Windows 2003 server. Looking at the event log, one of the databases appears to be restarting anywhere from every couple seconds to every 15 to 30 minutes. This server hosts about half a dozen databases; the problem is with only one. This database is also the onle one comprised of multiple schemas (not just dbo). There are thousands of events going back several months. There doesn't seem to be any affect on the website using the database, nor does any data appear to be corrupted or compromised. I'm not a DBA, so I don't even know where to look for causes to this. Any suggestions?

  • Windows boot manager and two hard disks

    - by Pincopallino
    here's my situation: I had an HDD with Windows 8 installed (UEFI mode). I bought a SSD and wanted to do a clean install of Windows, so I thought that disabling the HDD and leaving the SSD as the only drive when installing was the right procedure to install the boot manager on the SSD. Unfortunately, after I plugged the HDD back in, the computer won't boot unless I select from the BIOS directly the SSD as the boot device. I guess the problem is that I have two Windows Boot Managers on two separate drives and they conflict. How would I solve this problem (excluding a format of the HDD, because I need to access data on the old Windows partition and, ideally, I would like to be able to boot that partition)?

  • Whats the best way to deal with backups for my php/mysql application

    - by spirytus
    I'm creating php application for my client and now thinking what would be the best way to do backups, automatically if possible? I don't have much experience in this area and in case something goes wrong, or if I need to migrate, I would like to have fast way of getting it all back online. I understand "something goes wrong" is a very wide term, but lets say that someone hacks my site and wipes out database and all the files. My app. is written in php/mysql and I got access to cpanel (hosted with justhost.com if that makes any difference :). I used Joomla and it has JoomlaPack that does complete backup almost automatically and in case site fails, its easy to revert, or migrate if necessary. Is there anything like that for my configuration that would make reverting/migration, easy?

  • Graphics card for dual 2560 x 1440 output

    - by Bender
    As the title suggests I want to power two 2560 x 1440 monitors from one graphics card. I am just about to send my second graphics card back to Amazon, so before I purchase a 3rd incorrect card I thought I should get some advice. My latest card has dual DL-DVI output but only supports 2560 x 1440 on one output, the other maxes out at 1920 x 1080. Can graphics cards with two Dual Link DVI adapters (or alternately, one Dual Link DVI and one DisplayPort support the a full 2560 x 1440 on both monitors, or does that depend on the graphics hardware and not only the connectors?

  • Recommendations for SSD for server and database use?

    - by Tony_Henrich
    SSDs are a new technology and they are constantly improving. A lot of the posts here were posted in 2009 when SSDs where less mature and not as fast. What was recommend back then is probably out of date today because of better options. The SSD is used to hold SQL Server databases. Size is probably 128G. The database is used with a CMS and web server so web pages need to get their data and render as fast as possible. Which modern SSD is recommended for such a use? Is there an SSD better than Intel X-25 E/M in terms of performance/cost? (I am also evaluating cost between : RAM + UPS (semi persistent) vs SSD for same amount of gigabytes. No RAID is involved)

  • What is meant by "no password set" for root account (and otthers)?

    - by MMA
    Several years back, we were more accustomed to changing to the root account using the su command. First, we switched to the root account, and then executed those root commands. Now we are more accustomed to using the sudo command. But we know that the root account is there. We can readily find the home directory of user root. $ ls -ld /root/ drwx------ 18 root root 4096 Oct 22 17:21 /root/ Now my point is, it is stated that "the root password in Ubuntu is left unset". Please see the answers to this question. Most of the answers have something to this effect in the first paragraph. One or two answers further state that "the account is left disabled". Now my (primary) questions are, What is meant by an unset password? Is it blank? Is it null? Or something else more cryptic? How does the account becomes enabled once I set password for it? (sudo password root) In order get a better understanding, I checked the /etc/shadow file. Since I have already set a password for the root account, I can no longer see what is there (encrypted password). So, I created another account and left it disabled. The corresponding entry in the /etc/shadow file is, testpassword:!:16020:0:99999:7::: Now perhaps my above queries need to be changed to, what does an ! in password field mean? Other encrypted passwords are those very long cryptic strings. How come this encrypted form is only one character long? And does an account become disabled if I put an ! in the (encrypted) password field?

  • There's Not an App for That (Yet)

    - by Mark Hesse
    With an earlier-than-normal departure this morning to avoid the stalemate known as traffic congestion, I suddenly realized what I had failed to grab on my way out the door...  my company ID badge.  Unfortunately, at the time of my epiphany, I was far enough into commuter no-man's land where turning back would completely negate my early departure and increase my overall drive time exponentially.  Not being one to retrace my steps, I decided to press on. Upon arrival at the office and with an hour to go before a security guard would be on duty, I started thinking about the number of times I had forgotten my ID vs. the number of times I had forgotten my phone.  While rare on both accounts, my ID was most likely the missing artifact. I then wondered why there isn't an app for my smartphone that allows me to verify my credentials with my employer and then, provided with a secure token for the day, have the ability to access my building's card entry system.  On many levels, this seems much more secure than an ID card which can be lost, stolen or even forged and then used simply by tailgating into and around buildings at facilities where card scanning can generally be avoided.   As it turns out, another building on the campus has 24 x 7 guard coverage, so I was able to gain access in a relatively short time and secure a temporary ID badge.  Once inside and online, a quick internet search on the subject of smartphone badge access shows that efforts are underway to do exactly what I was thinking needed to be done. Having not spent any time studying about the technology, I discovered that it relies on Near Field Communications (NFC) enabled smartphones (of which, mine does not provide).  The only other option would require modifications to the security infrastructure to support alternative authentication technologies, such as barcode readers, which would be extremely costly to implement. For now, my best option is to put my corporate ID under my car keys...

  • Collider2D and Rigidbody2D, how do they work?

    - by user42646
    I have been learning JavaScript and Unity for a week now. I learned how to make Cube as a Ground and another Cube as a player and I used this code to make the Player Cube move forward and backward and jumping var walkspeed: float = 5.0; var jumpheight: float = 250.0; var grounded = false; function Update() { rigidbody.freezeRotation = true; if (Input.GetKey("a")) transform.Translate(Vector3(-1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetKey("d")) transform.Translate(Vector3(1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetButton("Jump")) { Jump(); } } function OnCollisionEnter(hit: Collision) { grounded = true; } function Jump() { if (grounded == true) { rigidbody.AddForce(Vector3.up * jumpheight); grounded = false; } } I also learned how to make a character hit box. how to make a sprite and animation. pretty much the basic stuff. Couple of days ago I created simple ground in Photoshop and a simple character and imported them to Unity3D. Whenever I use my code above the character keeps falling from the scene. Like the character has nothing to stand on. After thinking about it it make sense because I really didn't make anything to make the player character understand that he should stand on something so I started reading about this issue and I realized that there is something called Collider2D and Rigidbody2D. Now I'm really stuck here I just don't know what to do. I applied the rigibody2d to my character picture and the Collider2D to the ground picture but whenever I play the project the gravity makes my character falls down. This is my question: How can I make the rigibody2d object realize that it shouldn't fall if there is a Collider2D object under it? So when I jump it's going to jump and the gravity going to bring it back to the ground.

  • Blank screen on laptop after replacement

    - by Mark
    I have an Acer Aspire 5332 laptop, running Windows 7 home premium 32bit. My screen broke, but the particular screen (LED) are no longer made so I bought a CCFL one with a new converter which has proven to be compatible according to the supplier. When I first booted the screen went blank just after the Windows logo was displayed. I suspected a driver issue, so booted in safe mode without any problems, disabled the display adapter (Intel 4 series express family) and it booted up fine. So I guess the screen is not compatible with the display adapter. The driver version is 8.15.10.1892. I tried updating from the Intel site, but it saying it cannot (something to do with manufacturer specific). The supplier is not willing to take it back, so I'm down £60 (UK). I can use it with the adapter disabled, but the quality is bad and I cannnot play video, etc. Any help appreciated.

  • Accidentally deleted the software for MyPassport Essential SE 1TB Hardrive

    - by user26192
    Hi, I'm posting for a friend of mine. She bought a WD MyPassport Essential SE 1 TB Hard drive the other day. When she plugged in the USB in her lap top, the driver cannot be recognized by the smart ware software. While she was doing a back up of her files, McAfee was running in the background. Since the backup was taking so long to finish, she decided to pause it. She tried to delete the partially backed up files, but instead, she accidentally deleted the entire file in the folder including the pre-installed software. Now, when she tries to start up the MyPassport, the smart ware doesn't show up anymore. Can someone please give us advice what can she do about this? Thank you.

  • Sharepoint 2007: Edit vs Read Only Mode

    - by user29116
    Sorry about the title, dont' really know what it should be. If I open a doc in read only mode I'm able to press save and then it opens up a save as box and the default directory is the directory on the sharepoint server and if you press save you save it to the server. This actually makes the whole process not really "read only" mode since I could actually update the document. Is there a way to prevent this from happening so that if someone chooses read only there is no way possible to updload any changes back to the sharepoint site? Also, it has been suggested as a solution to get rid of the edit/read only option so that people have to check out the document. Is there a way to remove the edit/read only option on documents?

  • bluray playback stuttering/choppy on mac

    - by smashtastic
    I have had a few issues with bluray playback on mac with the following details: 2.4 GHz Core 2 duo NVidia 8600 m GT 256 mb ram 4 GB ram OSX Lion 10.7.5 Using VLC 2.03 for playback Files either mounted as a disc or stored on hardisk. I have tried various sources and playback is always choppy and stutters. Where the video and audio pause for a few seconds before resuming ok. If I transcode the same bluray files into mkv files play back is seemless. I am not applying any compression and the resolution is the same as is the nominal file size. For a recent example 11.2 GB m2ts and 10.5 GB mkv file. This stuttering and choppy playback of bluray files through VLC has occured for a number of different sources. For each of these sources transcoding to mkv solves the stuttering/choppiness. Any ideas on how to resolve this?

  • Ubuntu automatic logout whenever I execute exe files

    - by KeepTrying
    I have a problem. Here's the thing. There were 4 partitions in my hard drive: One for ubuntu root folder One for ubuntu home folder One for general stuffs like music, movies... And the last one for SWAP To install Windows 7, I resized partitions and moving the order of partitions by using GParted. I moved all of the ext formatted partitions to the left, so that means the spare space would be at the right. And I formatted that spare space in NTFS and install windows 7. After successfully installing windows 7, I used LiveUSB to fix grub. I installed Boot Repair and, with just one click, now I can dual boot ubuntu and windows 7. But, the point, because of changing the order of partitions, especially the partition consisting of home folder, I couldn't log in the ubuntu. I used recovery mode and changed file /etc/passwd. Everything almost got back to normal except one thing. The windows apps that I installed via wine don't work anymore. I run them via accessing menu Applications/Wine/Programs but nothing loads. One more thing, when I double click on exe files to run them, ubuntu suddenly log outs. Thank you for reading my post, it's quite long and my English is fairly poor. I'd appreciate for anyone who reads it.

  • My laptop keeps hard resetting

    - by cgoddard
    I have had this laptop for a long time (five years at least) and it hasn't had the best treatment over the years. But over the last few months, it has been randomly completely shutting down, no blue screening, no steady shutdown, just black screen, then BIOS. I think it might be happening as I do a save, but cant be sure, but recently it has been getting very annoying. I did initially think it was an overheating issue, but the speed that it comes back online is staggeringly fast for it to have cooled down sufficiently. plus it has got incredibly hot before with no issue (since its been doing this). Does anyone know what might be going on? Dell Inspiron 640m, running Windows 7.

  • Occasional HDD Related Hangs

    - by diolemo
    I have an issue that seems to be disk related. Occasionally my system will block for 30 or so seconds and is mostly unresponsive. Those things already in memory requiring no disk access continue to function but those things requiring disk access (even small) hang. 30 seconds later everything is back to normal. I have 2 Samsung drives in RAID 0. I have 1 WD drive (has pagefile) I have an SSD used for caching (Intel Smart Response). This is a new install of Windows and the drives were fine in my old PC (~1 month ago). Has anyone experienced anything similar? Any suggestions to solve this one? Thanks in advance.

  • nautilus will not start, no right click menu, apps will not run due to 64bit libicui18n.so.48 overwritten with 32bit, ubuntu 12.04

    - by Dewb
    yeah so i broke my system trying to install support for 32bit apps. Somehow the 32bit set of libicu*.so.48 files replaced my 64bit files and now nothing works. I know what the problem is and how to fix it , what i need is some help. I need some kind soul running a 64bit install of Ubuntu 12.04 to simply go into their /usr/lib dir and copy the files that have the form libicu*.so.48* (8 of them i think, maybe 16 i dunno how many there is supposed to be since they were overwritten). Anyway if you could put those files in an archive, zip or tar preferred and then email/share the link. I was able to get these files installed but they're from the latest edition of fedora and while i can now use my computer , it's not that stable things don't start right smoothly every time like they used to .... and well its a simple ordeal to put things back the way they were if someone wouldn't mind helping out. also any help setting up the libraries related to 32bit apps would be great as well as i apparently screwed that up royally. Thanks for any help or advice
