• Inconsistent slow DB connect times

  - by mcryan

  I have an app that shows significantly increased load times every 5 minutes. We use New Relic and I've been able to identify that every slow request is due to our DB connect functions. I've looked through our frontend servers and db servers and have ensured that there are no cronjobs running every 5 minutes - though the increase comes every 5 minutes without fail. I feel like I've tried everything I can to isolate this but I'm not having any luck. It is not coming from a cronjob, there is no cache expiring every 5 minutes, etc. What else could I check, and does anyone know of anything that could cause this sort of behavior? For what it's worth - our stack includes Apache, PHP, MySQL, Varnish and Memcache. SQL and memcache are running on dedicated servers and we have a number of frontend servers behind a load balancer, each running Apache and Varnish. Spike every 5 minutes: And it's always db connect (in red) taking up all of the time:

• What is the easiest way to copy Chrome's login/passses into KeePass without creating duplicates?

  - by ldigas

  Okey, here's the thing. I have most of my login info in two places; one is in Keepass file and the other is in Chrome. Being a lazy sort of person, and since Chrome/Keepass integration never really started to work the way it should, a couple times a year I use the Nirsoft tool to get the Chrome login/passwords into a textual .csv file and then import it in Keepass. Creating lots of duplicates in the process which I then clean and so on. In the meantime, all the new logins I accumulate just stay in Chrome. As you might notice, this is not really the best way to do it. Is there a faster way to do this; copy logins from Chrome to Keepass without creating duplicates in Keepass, or has anyone perhaps found a way to get Keepass to work with Chrome under Win XP SP3? Keepass 1.0 or 2.0, doesn't make the difference as long as it works.

• Replacing GRUB2 with Windows boot loader

  - by KovBal

  I'm trying to replace GRUB2 with Windows' standard boot loader (bootmgr?), but I can't get it to work. My Windows 7 install is in a single NTFS partition, which is marked as active (boot flag is set). First, I tried the automatic repair with the install disk, but it didn't detect any problems. Then I ran bootrec /fixmbr and bootrec /fixboot, but all I got was a black screen at boot with a blinking cursor. After that I created a boot partition for GRUB2, I figured, at least I can use it to chainload, but it give me a "disk reading error". If I used GRUB's ntldr loader, than I got error 0xc0000225 (some sort of BCD error). I tried to rebuild the BCD from the rescue environment, and it was successful, but the error didn't go away. Update: I've tried to rebuild the BCD, but nothing changed...

• Shortcut with arguments in Debian

  - by Duncan

  I have a volume on a debian server which contains a large number of images at full resolution in various folders. What I'd like to do is have a separate sort of browse proxy folder which contains lower quality browse copies of these to enable users to access them for viewing over lower speed dial in accounts. I'd ideally like these to be created on the fly using ImageMagick so there isnt the need to store the large number of browse copies full time and worry about keeping them up to date etc The way I'd invisaged this happening is the browse proxy folder containing a duplicate file and folder structure but with symlinks pointing to a script to transform them with the file path as an argument. Except I know this isnt possible with symlinks so am wondering if there's another way of doing this on linux. On windows shortcuts can take arguments and I'm wondering how to do the same on a Linux platform? (or perhaps I'm going about this the wrong way?)

• DataGraph alternatives for Windows systems

  - by ldigas

  Recently, on a friend's mac I came across a wonderful application for plotting in numerous ways numeric data - DataGraph. I've always done this sort of thing with Excel, and with newer versions, to me (this is emphasized "to me", so this doesn't get taken as an Excel rant post), it's becoming troublesome. Are there applications like this (specialized for one thing they do good and relatively simple ... I'm not interested in CFD visualization packages in here.) for Windows ? All suggestions welcomed.

• Which free open source CPanel and WHM alternatives do you recommend/use?

  - by Keyframe

  I have been using webmin for some time now, however I miss the elegance and ease of WHM/CPanel combo I've had on shared hosting (and later dedicated hosting) platform. Looking around the web, all I have found that is somewhat at the level of WHM/CPanel was webmin - but WHM/CPanel it is not. Since I'm using this only for our projects, it doesn't matter in the end really. However, we do put our new customers on our servers too, so some sort of CPanel might be an easier thing for them to cope with (mostly going about Email accounts stuff and such). Currently my stack is LAMP (CentOS and Ubuntu Server - several machines, probably ditching CentOS soon in favor of Ubuntu). There is a prospect of Python/Django instead of PHP, but it might take awhile.

• How many xml http requests is too much for a pc to handle?

  - by Uri

  I'm running mediawiki on an apache on a regular pc running vista (don't know the specific specs, but I'm guessing at least duo core 2 2 giga hertz processor, broadband connection (500 kb/s at least, probably 1 mega). I want to use the MediaWiki api to send a lot of requests to this server. Most of the time the requests will be sent through LAN (but sometimes through the internet). I'm talking thousands of requests every few seconds at worst case. (A lot of these requests may repeat themselves, I guess some sort of cache would help) Will the server handle this, or do I need a stronger/dedicated computer? (I'm not looking for specific yes/no, but just want to get an idea as to what configuration of computer will support how many request per second) Thanks

• Best practices for FQDN for standalone domain (is a two part domain.tld okay?)

  - by birchbark

  I've searched quite a bit and can't seem to find a straight, modern answer on this. If I am hosting a domain, say, mydomain.com, on a machine which is going to solely be used for that domain, and there are no subdomains, is there a real, practical reason besides compliance to create an arbitrary hostname (i.e. myhost) just in order to have a three-part FQDN (myhost.mydomain.com) to satisfy some sort of RFC or convention that's expected. This seems to make a lot of undue complexities from my perspective, and I'm not sure if there's an advantage to this or if it's just a hold-over from a time where all web resources came from a subdomains such as www and ftp which may need to scale to separate machines. I don't use www on my domain, either, which is ill-advised for all I know from an administrators perspective (though removing it is the norm from a designer's perspective)...

• Received a RAMPAGE IV FORMULA MOBO. Possible CPU Socket problems

  - by Tantan

  I recently received a Rampage IV Formula MOBO in a trade. From everything I read online this seems like a pretty nice piece of hardware. There's one thing I'm worried about though. It appears as though the socket where the CPU goes might have some bent/missing pins. I'm not exactly a computer expert and I wanted to know if this could be any sort of problem. I would post a picture but I apparently don't have enough rep for that... Also, if I did want to move my current rig onto the new MOBO would it even be worth it? MY CURRENT COMPUTER SPECS i3-3220 CPU 8GB DDR3 RAM GeForce GTX460 GPU With a Biostar MOBO!

• Checking that tasks are executed

  - by homer5439

  I'm not sure how to explain this. Once one starts having dozens or hundres of servers, each running some sort of periodic jobs (mostly from cron), there is a problem of making sure (or as sure as possible) that these tasks are actually ran. I mean, I get an email if a job fails fails, and no mail if it succeeds, but also no mail if it doesn't run for whatever reason. Sure, I could change them and have them send a "successfully ran" email, only to be flooded by mails that most of the time I don't want to see. Basically, I want to be notified only if: a task ran and failed a task didn't run at the expected time. Is there a way to do this?

• Windows 8.1 reset

  - by CreeperInATardis

  I recently had a massive crash on my Windows 8.1 partition, which has rendered it (practically) unusable. I tried to do a refresh, but the problem is, I have a Windows 8 install disk, not 8.1, and thus it didn't work. I also do not have any system restore points/backups of any sort, but I have managed to move my files off. Also, I do not know where my product key is (and cannot find it online), so a clean reinstall would not work. My question is, is there any way to change my Windows 8 disc into an 8.1 disc to allow me to refresh/reset my PC, or is there any other way to do this (aside from repurchasing?) Thanks!

• Automatic Reply Out of Hours

  - by Inbr3d

  Is there a way i can use a rule or "timer" of some sort to turn on out of office, or enable an auto reply for 1 mailbox (Sales mailbox) within a time period. Reason: We deal with all timezones, we only open 6am-8pm. critical sales are sometimes lost the automatic reply will involve a telephone number for emergency sales. (yes, spam i know) I wish the auto reply to come from "[email protected]" if this is possible. I've lokekd at transport rules, cant see anything. I cant word my question well enough for google to give an answer.

• Recommendation for hardware upgrade: thin clients? Or...?

  - by Alex C.

  I work for an animal shelter in Upstate New York. We have about 50 machines running XP Pro. They're connected to a Windows network with a domain. About half of these computers are used for nothing more than using two web-based apps -- one to keep track of our animals, the other to process credit cards. Having a full-blown desktop PC seems like overkill for this purpose. The PCs are three-to-five years old, and I'd like to come up with a plan to upgrade the hardware. Our donations are down (not surprising, given the economy), so cost is a big factor. Can people recommend some options? Some sort of thin client, maybe?

• Active Directoy GPO

  - by Phillip R.

  I am looking into some weird issues with active directory and group policy. This domain has been upgraded from windows NT and has a few different administrators over the years. I am looking through the Default Domain group policy and Default Domain Controller group policy. In the security areas and I will use the log on locally area as an example, it shows SIDes that begin with asterisks and are quite long they look sort of like the following *S-1-5-21-787626... Normally, when I see something like this I would think that the User account was no longer there and this was never cleaned up. Am I wrong in my assumption? Thanks in advance

• how to trace an outlook mail not arriving to its destination when is sent to another domain?

  - by Alex. S.

  Hi, I have an domain account configured with Ipower.com. If I use an email client such as Evolution, the mails arrive as expected. However if I use Outlook 2007 (as everybody in this company) the mails only arrive if the destination belongs to the same domain. That means when the destination is a gmail address, for example, the test email falls into a sort of black hole... This is just a simple ipower setup, nothing of Exchange or something like that. What else can I do to isolate and fix this issue? This is driving me nuts because in other email client with the same exact configuration in the same machine, everything works well and I need to fix the thing in Outlook.

• My stereo headphones cable is broken, what can I do?

  - by ucas

  I have a pair of stereo headphones, I got them on Amazon. Now, the right headphone stops producing sound. To fix that I need to move/shake the tip of the cable (the one before that part of tip which goes inside the headphone jack on the laptop). But as time goes, this sort of fix helps less and less. It looks that the cable is a bit broken at the place where I shake/move cable. Is that the end of use of my headphones? Is that a reject of the device? Is there a way to fix it, for example, changing the very tip of the cable at the very end of it. Any advice on buying headphones?

• Upgrade to java 1.7 in eclipse on mac

  - by user2159614

  I'm sort of a beginner with eclipse but I want to update the libraries or build path or whatever to java 1.7 from java 1.6 and I can't figure it out. I'm a computer science student at the university of washington and various TA's and students have tried to figure out this problem but it's stumped them all. I've installed java 1.7 from Oracle a few times already and the java section of system preferences says I have 1.7 but java -version in terminal says: java version "1.6.0_41" Java(TM) SE Runtime Environment (build 1.6.0_41-b02-445-11M4107) Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01-445, mixed mode) What's going on here? My mac is totally up to date on everything else

• A script so that you don't forget your usb drive on a public computer

  - by Ava Gailliot

  So I have a problem because I'm an idiot. I seem to always leave my usb drives in public computers at school and the like. I unmount them and log off leaving them still in the pc, and of course I then lose my information and my drive which can be costly. Is there a small script somewhere that I can install to my drive that prompts me to take out my usb stick when I log off of a computer? Since this is mostly for use with public computers I can't put anything on my drive that will later need some sort of admin permissions. I guess if all else fails I'll probably put my drive on a lanyard and keep it around my wrist. lol. Does anyone else have this problem?

• Visual Studio 2012 intermittent lockup

  - by user1892678

  Visual Studio 2012 intermittently locks up on me. I notice that devenv.exe jumps to 50% CPU utilization. The CPU stays at this level for a few minutes and then drops. While its at 50% utilization I can still use the IDE. However, intermittently it stops responding (as though it was performing some sort of background process). It only lasts for a few seconds. Also this happens when debugging. I'm running under Windows 7 and I'm using Telerik controls. I've disabled add-ins and extensions and have had no success. Any ideas would be appreciated? Thanks

• How to monitor a folder and trigger a command-line action when a file is created or edited?

  - by bigmattyh

  I need to set up some sort of a script on my Vista machine, so that whenever a file is added to a particular folder, it automatically triggers a background process that operates on the file. (The background process is just a command-line utility that takes the file name as an argument, along with some other predefined options.) I'd like to do this using native Windows features, if possible, for performance and maintenance reasons. I've looked into using Task Scheduler, but after perusing the trigger system for a while, I haven't been able to make much sense of it, and I'm not even sure if it's capable of doing what I need. I'd appreciate any suggestions. Thanks!

• What components should I upgrade to squeeze more life of my pc? [on hold]

  - by Jared

  Hi my current specs are CPU: Intel Core i5 750 2.66 GHz, Socket 1156 Motherboard: Asus P7P55 LX Motherboard, Socket 1156, 4xDIMM DDR3, 2xPCIe-16, 3xPCI, 2xPCIe-1, 14xUSB2, Audio, 1xATA, 6xSATA, RAID, ATX HDD: Seagate Barracuda 7200.11 ST31500341AS Hard Disk Drive, 1500GB, 7200rpm, 32MB Cache, SATA-2 RAM: G.Skill Ripjaw F3-12800CL8D-4GBRM, 2x2GB, DDR3-1600, PC3-12800, CL8, DIMM Video: MSI Radeon 5850 R5850-PM2D1G Video Card, 1024MB, DDR5, PCIe-16, DVI, CrossFire, HDMI PSU: Vantec ION2, 620W ATX PSU, SLI Ready, Black Firstly I know it badly needs an SSD, for which I'm thinking of the Samsung 250gb 840 EVO series. The ram could do with another 4GB, for which I am thinking of replacing the 2x2GB for 2x4GB of the same type. My video card is struggling with the latest releases, so vitally should I ditch the video card and go for something newer (ATI 7850, GTX 660?) or try and get another 5850 for crossfire support? Bearing in mind 5850's are sort of hard to come buy now as they are not stocked in shops usually, which means they have to be bought second hand.

• Compress snapshot backups with duplicates

  - by Usavich

  I have a set of backups of mostly photos. The directory looks sort of like this: backup/Day1/photos/1.jpg .../2.jpg backup/Day2/photos/2.jpg .../3.jpg .../4.jpg backup/DayN/photos/2.jpg .../3.jpg .../9.jpg Files with same name are identical. There are many duplicates. Due to the way the backup system works, it's not possible to create incremental backup directly. I always get the entire dump each day. If I want to create a compressed archive for a date range, say Day 5~9, what is the best tool/compression algorithm to do that?

• How to test which button is stuck

  - by Macha

  My laptop's keyboard is prone to buttons sticking. The fix is to just press the same button again. Now when it is the letter/number keys are stuck, it's just a matter of putting the cursor in a text field, and seeing what characters appear. However, when it is one of the modifier keys, or tab, or enter or a few other buttons, it gets harder to tell which key is to blame. Trying to type can result in all sort of shortcuts being triggered. Is there anyway to test what input is being recieved? Also, I'm guessing this is a hardware issue, but if anyone knows of any possible causes/solutions it'd be appreciated. It's a Dell Studio 17, and the problem occurs under Windows and Linux.
