• netbook losing internet connection

  - by cometbill

  I have a netbook that occassionally, usually once or twice a day, maybe more, will lose its internet connection while I am on Skype (that's when I notice it most, it may happen more often). The little yellow dot appears over the networking icon in the system tray, which when I click on it says no internet access at the top of the popup menu, and next to the router connection that I have. Disconnecting and reconnecting usually rectifies full internet access again. I'm not sure if leaving it for any amount of time allows the netbook to automatically reconnect again. Everything seems fine with my laptop. I don't think this loses connection in the same way. I'm using Windows 7 home premium.

• Tuning MySQL to consume less memory

  - by Alex

  I have a VM which has 2GB Ram, (full specs) And I am setting up a site which has one table in particular with over a million records. There's little or no usage of this particular database (perhaps once or twice a day) but simply running mysql grinds the whole server to a halt. I've looked through the top results but nothing is really denting the CPU however the memory seems to be the issue. The site isnt even live of taking requests yet. the memory situation looks like this: # free -m total used free shared buffers cached Mem: 2006 1880 126 0 3 53 -/+ buffers/cache: 1823 183 Swap: 2047 345 1702 Are there any good pointers to tune mysql to stop hogging the system memory? Thanks very much EDIT: (requested by 8bit): http://tny.cz/b41a0b12

  - by Darktux

  I am trying to write a script which collects security log from all of our domain controllers hourly and stores them remotely; i can collect the security logs , but is there a way to collect the security logs by category or event number from the DC? please do let me know if any additional questions. My Code: $Eventlogs = Get-WmiObject -Class Win32_NTEventLogFile -ComputerName $computer Foreach($log in $EventLogs) { if($Log.LogFileName -eq "Security") { $Now = [DateTime]::Now $FileName = "Security" +"_"+$Now.Month+$Now.Day+$Now.Year+"_"+$Now.Hour+$Now.Minute+$Now.Second $path = "\\{0}\c$\LogFolder\$folder\$FileName.evt" -f $Computer $ErrBackup = ($log.BackupEventLog($path)).ReturnValue if($clear) { if($ErrBackup -ne 0) { "Backup failed" "Backup Error was " + $ErrBackup } } } } Copy-EventLogsToArchive -path $path -Folder $Folder }

• Backing up data (including mysqldumps) to S3

  - by seengee

  We have a web app on a number of servers and we want to add an additional layer of redundancy by backing up the key data to S3. The key data is the MySQL database and a folder containing dynamically created site assets - predominantly images. Some kind of rsync based solution would initially seem the best plan. A couple of years ago we played with S3cmd (in particular s3cmd sync) with some success but we didn't find it particularly reliable although this may have changed since. Its occurred to me though that a rsync solution might not work particularly well with a single db.sql file created with mysqldump and I assume this means the whole database getting transferred each time, with multiple databases of over 1GB this is going to add up to a lot of traffic (and $s) very quickly. With the image files I could simply just transfer files modified within the last day which would be far more simple. What approach should I look at?

• Why does my general frame rate slow down to 40fps randomly?

  - by Joshua

  This has been bugging me for a while. Every once in a while, I find my computer to be sort of laggy and I thought it was because it was busy or something. However, I recently noticed that it wasn't any performance issue...I thought my computer was laggy because the frame rate slowed from 75fps right down to ~40 fps and caused very visible tearing. This is not rare. It happens many, many times a day. I have no idea what is happening...I have an AMD 5670 on Windows 7 32-bit by the way, and I've heard bad things about AMD's driver support. Could this be the problem? P.S. The frame rate slowdown is not just for games (I rarely play games, and have not played games in the time since I noticed this problem), it seems it's an issue for the entirety of Windows. I first noticed the tearing when I was moving around tabs in Google Chrome.

• SharePoint Calendar - Start time after a certain hour

  - by KodovaKim

  I am working with SharePoint Calendar list to create a shift schedule for a team (End user side of things, I am not writing code). I have added a few custom columns to the Calendar List Item. I have the list exported to excel where I have a Pivot table set up so I can see a summary of the different columns - I can see the person's name (From the title column), total hours they are scheduled for (separated into weekdays and weekends based on a custom column I added). What I need is a way to check the start time of the shift to determine if it is a Day shift (starts at 7am), Eve shift (starts at 3pm), or a Night shift (starts at 10pm). So, when creating a new calculated column I would assume the function I need would go something like "=If([StartDate]...." but I am not sure on the rest. Anyone know how I would write that function?

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

  - by user26192

  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.

• Computer Loses connection to router

  - by ajon

  I have a new Windows 8 Dell XPS desktop computer at work. It has a Dell Wireless 1703 802.11 b/g/n (2.4ghz) wireless adapter. sporadically throughout the day I lose internet connectivity. When I click on the wireless system tray icon, my companies router does not appear in the list. No other computer on the network is losing connection, only this one. I don't even know what to check. Could it be an ip conflict that causes me to get booted off? (I use DHCP), but why wouldn't my computer be able to see the network. The next time it happens I will see what happens when I try to access the router directly.

• Internet printing : print to iOS gateway -> AirPrint / something -> Laser printers

  - by user75129

  I've done a bit of research on the Internet, and it looks like I'm on a dead end. My goal is to minimize cost, and be able to send and print documents AUTOMATICALLY (may be 10 or 20 pages per day) to a laser printer in a remote office. The preliminary method is to use: iOS 5.1.1 (JB'ed) with 3G connection, HP (or other brands) printer with AirPrint, iCloud's Documents and may be write some launchd scripts to monitor any new documents in iCloud. May be with other software. I am not sure yet. By using the cloud, I can upload new docs to the cloud anywhere in my city, and the iOS will be able to see them within a reasonable amount of time, then print it. But it seems this combo is not workable. Anyone got any advice on how to make this set up work, or propose other alternatives that requires NO PC or Mac? Currently I have a 3GS with 3G connectivity spare. Need to buy a new printer though.

• Why do some devices seemingly need the wifi router to reboot before they can connect?

  - by CreeDorofl

  I've noticed a pattern but I'm not sure if it's a crappy router, crappy wireless device, or maybe everything is working as intended. I can wirelessly connect my office PC to the router's settings page for a day, maybe two, then afterwards I can't anymore until it's reset. Unrelated, but similar, in various places that offer free wifi, my kindle will connect fine most days, but occasionally won't unless the router is reset. After the reset, I connect ok. What's happening behind the scenes that makes a router stop allowing you to connect? Is it something on my end that's changing, or on the router's end?

• SSL Certificate Expiry: Does the expiry time make any difference at all?

  - by CYMR0

  I need to know when an SSL certificate actually expires. Does it just look at the expiry date, or does it also take into account the expiry time? Let's say a certificate expired on 1/1/2013 at 11am. Does that certificate expire at 11:01am or is it only the following day that the certificate expires? I have been told both are true. Hope that makes sense! Our suppliers messed up and let our certificate expire, and I'm trying to figure out how much compensation we're owed. I found this question Details on exact expiration datetime of an SSL certificate? but it didn't quite answer what I need (and I didn't like to revive a dead question).

• How to set default permissions for automounted FAT drives in Ubuntu 9.10?

  - by piman

  I've got many FAT32 drives that I'd like to mount in Ubuntu such that they have permission mode 700 for directories and 600 for all other files. By default, they have 755 for all files, which is not particularly useful since almost no non-directories should be executable, and it screws up version control repos hosted on the drives. "Back in the day" I would have had the drives listed in /etc/fstab with the umask/dmask I want and there was no such thing as a default. These days, drives automount under their volume names. Which is great, except now I have no idea how to set the default. I have tried changing the /system/storage/default_options/vfat/mount_options gconf key with no apparently effect. It was 077 initially but the mounted drive reflected a default of 022; changing it and re-inserting the drives resulted in the files still having permission bits of 755.

• Nested IF statement on Google Spreadsheet, second part same as the first [migrated]

  - by lazfish

  I have a spreadsheet for my budget. Payments are either drawn from my bank or my Amex card and then my Amex card is drawn from my bank as well. So I add up all my monthly total like this: =sumif(I3:I20,"<>AMEX",D3:D20) Where I3:I20 = account bill is paid from and D3:D20 is monthly amount due. So I am not including bills that come from my Amex card in the total since the Amex bill itself covers those. Next I have a column that has the day of the month 1-10 (when everything gets paid) and it does this: =sumif(H3:H20,E24:E33,D3:D20) Where H3:H20 = date bill is paid and E25:E35 = range from 1-10. What I want to do is make this second part do the same check as the first. Something like this: =sumif(H3:H19,E24:E33,IF(I3:I19"<>SPG",D3:D19,0)) But I get error: "Parse error" What am I doing wrong?

• MS Word showing unwanted table borders on screen (but not on print preview)

  - by Jivlain

  I have a MS Word document with a number of tables. The other day when I created it, the tables all had no borders. Today, I opened it up to find that the tables did have borders. However, when I check the border properties on each table, it says that there are no borders. The tables are displayed with cell borders in all view modes except for the reading layout, and they do not show up on print preview. As this document is going to generally be for on-screen viewing, I need to get rid of the borders. How can I accomplish this? (this is a MS Word 2003 *.doc document, in MS Word 2003, which has been the only editor involved.)

• Possible to change the order of the shortcut locations in windows explorer

  - by Codezilla

  When you open a new explorer window by default it loads from the starting position "Computer" which shows your drives, etc. This is all well and good except when explorer loads it bumps the scroll bar down so that half the favorites are cut off. I can scroll up to get to the ones I want but that gets really old doing that 50 times a day. I do clean out my favorites frequently but more are added all the time and used. In trying to come up with a fix for this problem I thought maybe it would be possible to move the link to "Computer" to be at the very top and the "Favorites" area directly under that but I can't figure out a way to do that. Anyone have an idea? Or maybe another solution I haven't thought of?

• How can I incrementally backup a large amount of data [with rsync]?

  - by Annan

  A website contains ~40GB images + files which needs to be backed up. Rollbacks need to be possible daily for the last 30 days. And backup server < 1.2TB My idea is to have one full backup from 30 days ago, then incremental backups for the last 30 days. On each day the last incremental backup is combined with the full backup and a new incremental backup is added. Can this strategy be implemented with rsync, if so how? Are there any problems with this plan? A better plan? PS: Incremental backups, not backup incrementally (which rsync does automatically)

• I modified my registry and now my laptop doesn't report its battery or power settings

  - by Crouch

  I saved a backup of my registry and then made a change to it. After the change, the Windows 7 battery meter no longer reported how much battery power was left. I also was no longer able to change between Power Profiles in the Control Panel. I tried to restore the original registry but it didn't restore the lost power features. Now I have to keep my laptop plugged in all day because I never know how much power I have left. Anyone know what to do here?

• Windows 7: enabling navigation of subfolders in pinned Start Menu folders

  - by AspNyc

  I'm just about to move from Windows XP to Windows 7, and I'm struggling with some of the interface changes. In XP, I was able to throw a folder intoC:\Documents and Settings\username\Start Menuand have it appear on the Start Menu, complete with the ability to navigate through subfolders. I've figured out how to pin a folder onto the Start Menu in Windows 7, which required a registry hack. However, I am unable to view the subfolders of the pinned folder without opening a new Windows Explorer window. Is there any way to replicate the old XP behavior I'm used to? I'd like to be only a single click away from these handful of application links and folders, since I use them all the time throughout the day.

• Spam is Killing Me - Can I use GMail as a spam filter?

  - by kirkouimet

  I'm getting at least 50 Viagra ads a day and it's driving me insane. I currently have a hosted MS Exchange account and a Gmail account. My Gmail account forwards to my Exchange account. Both of my addresses are used evenly, and it has been really nice to have all of my e-mail end up in my Exchange box. I like replying from one address consistently, which is my Exchange address. Spam sent to my Gmail address is always caught, where spam sent to my Exchange is getting passed straight through to me. I don't want to have two spam filtration systems that have quarantines that I need to check frequently for false positives. Here is my question: Can I setup my MX records such that all e-mail sent to my Exchange address is forwarded to my Gmail account, which will then forward it to my Exchange account? Kind of like using Gmail as the middle man.

• Exchange retention work cycle properties

  - by marcwenger

  I've setup retention tags and policies in Exchange, but only run when I execute start-managedfolderassistant Upon running the command get-mailboxserver | fl name,*workcycle*, *ManagedFolderAssistantSchedule*, I noticed the following fields (truncated): ManagedFolderWorkCycle : 1.00:00:00 ManagedFolderWorkCycleCheckpoint : 1.00:00:00 ManagedFolderAssistantSchedule : {Sun.1:00 AM-Sun.9:00 AM, Mon.1:00 AM-Mon.9:00 AM, Tue.1:00 AM-Tue.9:00 AM, Wed.1:00 AM-Wed.9:00 AM, Thu.1:00 AM-Thu.9:00 AM, Fri.1:00 AM-Fri.9:00 AM, Sat.1:00 AM-Sat.9:00 AM} The first two are set to run every day, but does this conflict with what is set in ManagedFolderAssistantSchedule? What's the difference between ManagedFolderWorkCycle and ManagedFolderWorkCycleCheckpoint?

• Disable "Print and Close" Preview Shortcut on OS X Mountain Lion (10.8.2)

  - by Twitch_City

  I recently upgraded to Mountain Lion from Leopard and there is a global shortcut that I would really like to disable. Apparently, now if you select a document and press Command + p, Preview will open, print the document, then close. I'm sure this was done with the purest intentions but, unfortunately, it is right next to Command + o, which I use many times a day to open files. Since installing Mountain Lion, I've accidentally printed way too many documents just trying to open them! I've gone into the Keyboard preference pane and tried to find where this shortcut is located, but haven't had any success. Anyone know how I can disable this?

• Google Chrome giving error 138

  - by gsingh2011

  Google Chrome randomly stopped working one day and is giving me this error: Google Chrome is having trouble accessing the network. This may be because your firewall or antivirus software wrongly thinks that Google Chrome is an intruder on your computer and is blocking it from connecting to the Internet. Here are some suggestions: Add Google Chrome as a permitted programme in your firewall or antivirus software's settings. If it is already a permitted programme, try deleting it from the list of permitted programmes and adding it again. Error 138 (net::ERR_NETWORK_ACCESS_DENIED): Unable to access the network. I didn't make any changes to my firewall settings between the time it was working and when it wasn't working. I'm using the default Windows Firewall. I added Chrome to the allowed programs and restarted, but that didn't fix the error. I even reinstalled Chrome completely and that didn't work either. Any help would be appreciated. EDIT: I forgot to mention that Firefox and IE9 work fine.

• Smart backup software

  - by gisek

  I use a laptop on daily basis. As I have a lot of important data there it would be nice to do backups of some directories every day. Can you recommend a specific application that would take care of it? Maybe there is an app that would instantly commit changes I make in a directory on my laptop to the backup folder? The important thing is that I have some big files (a few GB's) that have some minor changes very often. I'm talking about VirtualBox disk images. It would be nice if the software could handle it smartly. Also notice that I'd like to store it on an external usb HDD, which sometimes isn't plugged in.

• PCs with Wired Connection Keep Losing Internet Connectivity

  - by user717452

  I have a U-verse ATT DSL Internet at our church building. Recently, any computer that is plugged into the network via Ethernet keeps losing its internet connectivity. The setup is from the Modem to a Netgear Wireless Router, and from the router to 3 different computers. None of the laptops that use Wifi ever lose internet, just the wired ones, and I end up having to do ipconfig /release and /renew every day to get it back. One computer has Windows 7 and one has Windows XP. Any ideas as to what is going on with our network?

• Tests for hard drive health

  - by Samik R

  I have a 5-year old hard drive (bought new at the time), but it was sitting in my closet for 5 years, unused. I have just started using it, and seems to be getting a whirring sound (rather distinct from the other noises like fans etc.). I ran a few diagnostics tests, like Seagate's SeaTools, and the SMART test, and a few generic tests and all passed. Should I be concerned? Is there any other test that I should run? It's an internal IDE WD 5400RPM drive. Being used for a desktop, which is itself pretty high-end (AMD Phenom II X6 1100T, AMD Radeon GPU etc.), but would be used rather occasionally to begin with (avg. 1-2 hrs. per day). Thanks for any pointers.
