  • How to get both PIPESTATUS and output in bash script

    - by Mustafa Serdar Sanli
    I'm trying to get last modification date of a file with this command TM_LOCAL=`ls -l --time-style=long-iso ~/.vimrc | awk '{ print $6" "$7 }'` TM_LOCAL has value like "2012-05-16 23:18" after execution of this line I'd also like to check PIPESTATUS to see if there was an error. For example if file does not exists, ls returns 2. But $? has value 0 as it has the return value of awk. If I run this command alone, I can check the return value of ls by looking at ${PIPESTATUS[0]} ls -l --time-style=long-iso ~/.vimrc | awk '{ print $6" "$7 }' But $PIPESTATUS does not work as I've expected if I assign the output to a variable as in the first example. In this case, $PIPESTATUS array has only 1 element which is same as $? So, the question is, how can I get both $PIPESTATUS and assign the output to a variable at the same time?

  • Adding FK Index to existing table in Merge Replication Topology

    - by Refracted Paladin
    I have a table that has grown quite large that we are replicating to about 120 subscribers. A FK on that table does not have an index and when I ran an Execution Plan on a query that was causing issues it had this to say -- /* Missing Index Details from CaseNotesTimeoutQuerys.sql - mylocal\sqlexpress.MATRIX (WWCARES\pschaller (54)) The Query Processor estimates that implementing the following index could improve the query cost by 99.5556%. */ /* USE [MATRIX] GO CREATE NONCLUSTERED INDEX [<Name of Missing Index, sysname,>] ON [dbo].[tblCaseNotes] ([PersonID]) GO */ I would like to add this but I am afraid it will FORCE a reinitialization. Can anyone verify or validate my concerns? Does it even work that way or would I need to run the script on each subscriber? Any insight would be appreciated.

  • MySQL doesn't talk to PHP anymore (EasyPHP)

    - by Matt Ellen
    I've just upgraded from Windows XP to Windows 7 (64 bit) I was using EasyPHP 5.3.1 to develop my website, but since I've upgraded I can't get PHP to talk to MySQL. Even the PHPMyAdmin page doesn't load. I've tried installing the latest 64bit version of MySQL in place of the supplied version of MySQL, but that hasn't helped. The queries just don't seem to reach MySQL. I have verified that the DB for my database works by running mysql on the command line. PHPMyAdmin doesn't display an error, just a blank page. The error coming up from my website is: Warning: PDO::__construct() [pdo.--construct]: [2002] A connection attempt failed because the connected party did not (trying to connect via tcp://localhost:3306) in E:\services\EasyPHP-5.3.1\www\IdeaWeb\classes\Security.inc on line 14 Fatal error: Maximum execution time of 60 seconds exceeded in E:\services\EasyPHP-5.3.1\www\IdeaWeb\classes\Security.inc on line 0 Does anyone know how to solve this? (i.e. get MySQL talking to PHP.)

  • HP DL180 G6 P410 8x SATA 1TB, what is the optimal configuration?

    - by Oneiroi
    I have a HP DL180 G6 with a P410 raid controller. Presently this runs using 4x 1TB Samsung Spinpoint SATA drives, in a RAID10 configuration using default settings. I am about to add a backplane to increase the drive capacity from 4 to 12 drives, and I plan to install 4 more 1TB SATA Drives. The drives are matched and have close serial numbers (They arrived together in the Manufacturers pallet). Model HD103UJ 1000GB/7200rpm/32M Rated for 3GB/s I will also be installing RHEL 6.1 x86_64. My question is what would be the optimal RAID settings (stripe etc.) for this configuration? To recap: 8x Model HD103UJ 1000GB/7200rpm/32M Rated for 3GB/s RAID 10 configuration. Thanks in advance. Update for role: Server is to become an iscsi target for an internal openstack deployment currently underway. (Glance) Will also provide virtualisation through KVM

  • How do I explain this to potential employers?

    - by ReferencelessBob
    Backstory: TL;DR: I've gained a lot of experience working for 5 years at one startup company, but it eventually failed. The company is gone and the owner MIA. When I left sixth-form college I didn't want to start a degree straight away, so when I met this guy who knew a guy who was setting up a publishing company and needed a 'Techie' I thought why not. It was a very small operation, he sent mailings to schools, waited for orders to start arriving, then ordered a short run of the textbooks to be printed, stuck them in an envelope posted them out. I was initially going to help him set up a computerized system for recording orders and payments, printing labels, really basic stuff and I threw it together in Access in a couple of weeks. He also wanted to start taking orders online, so I set up a website and a paypal business account. While I was doing this, I was also helping to do the day-to-day running of things, taking phone orders, posting products, banking cheques, ordering textbooks, designing mailings, filing end of year accounts, hiring extra staff, putting stamps on envelopes. I learned so much about things I didn't even know I needed to learn about. Things were pretty good, when I started we sold about £10,000 worth of textbooks and by my 4th year there we sold £250,000 worth of text books. Things were looking good, but we had a problem. Our best selling product had peaked and sales started to fall sharply, we introduced add on products through the website to boost sales which helped for a while, but we had simply saturated the market. Our plan was to enter the US with our star product and follow the same, slightly modified, plan as before. We setup a 1-866 number and had the calls forwarded to our UK offices. We contracted a fulfillment company, shipped over a few thousand textbooks, had a mailing printed and mailed, then sat by the phones and waited. Needless to say, it didn't work. We tried a few other things, at home and in the US, but nothing helped. We expanded in the good times, moving into bigger offices, taking on staff to do administrative and dispatch work, but now cashflow was becoming a problem and things got tougher. We did the only thing we could and scaled things right back, the offices went, the admin staff went, I stopped taking a wage and started working from home. Nothing helped. The business was wound up about about 2 years ago. In the end it turned out that the owner had built up considerable debt at the start of business and had not paid them off during good years, which left him in a difficult position when cashflow had started to dry up. I haven't been able to contact the owner since I found out. It took me a while to get back on my feet after that, but I'm now at University and doing a Computer Science degree. How do I show the experience I have without having to get into all the gory details of what happened?

  • Android tethering question

    - by Solignis
    Hi there, I have a Motorola Droid 1 with Android 2.2 on it. I found something odd that I don't understand why it works. If I plug my phone into my home computer which is Windows 7 and I turn on the tethering ability, I am met with a Verizon captive portal and it tells me I need to pay for a tethering plan (which I don't have). Now the weird thing, if I plug the same phone into my Ubuntu 10.10 laptop and enable tethering it works and can get on the internet with no captive portal showing up. The only thing I could notice that was different about the connections was Windows connected to the phone with an NDIS driver and Linux connected to the phone with what I think is a raw device mapping. Would that have anything to do with it?

  • MSSQL:Ultimate configuration for rebuilding indexes+statistics

    - by Niels Bosma
    My database is growing slower even though I have a bunch of indexes setup. Yesterday I figured out that I need to setup a maintenance plan to build the indexes etc. So my question is what's the ultimate configuration for this? Do I need All: "Rebuild idex task", "Reorganize index task" and "update statistics task". Anything else I need to setup. Shrink database? (Today, the only maintenance plans I have is backup) Does it matter in what order I run them? Any configuration options I should be aware of? I've read of problems with log growing wild, how do I fix that? My transaction log is quite small and is usually a problem for me. -

  • Converting AVI to FLV in highest quality

    - by Josh
    I want to convert some of the AVI files I recorded (presentations) to FLV so I can host them on a website and offer them to my visitors. I have done this sort of thing before but the quality they came out as would not be good enough for what I plan on doing here. So does anyone have a link to a guide or any experience they can offer in converting AVI to FLV with minimal quality loss? A lot of my presentations are 720p aswell, so I'd want to keep the aspect ratio the same as the source video. Thanks in advance.

  • Can I upgrade an Asus M51Sn laptop to 2x4GB of RAM? (DDR2)

    - by matteo
    My Asus M51Sn has 2 RAM slots which currently have 1x1GB + 1x2GB DDR2-800 SODimm RAM modules installed. I've found out that 4GB DDR2 SODimm modules do exist, though they are impossible to find in local stores nere here, but I've found them in online stores like these: http://www.pccomponentes.com/g_skill_ddr2_800_pc2_6400_4gb_so_dimm.html They seem to meet the specification, so can I replace both my current modules with 2x4GB modules, and reach a total of 8GB? Or should I worry about some limit (e.g. 4GB max or 2GB per slot) imposed by the matherboard, chipset or whatever? (I currently use Ubuntu 12.04 32 bit, so I plan to use the pae kernel, which supposedly supports 4GB ram on a 32bit system; or I may consider switching tu 64bit ubuntu; the question is about hardware limitations, not OS limitations).

  • Why do I get "Sequence contains no elements"?

    - by Gary McGill
    NOTE: see edits at bottom. I am an idiot. I had the following code to process set of tag names and identify/process new ones: IEnumberable<string> tagNames = GetTagNames(); List<Tag> allTags = GetAllTags(); var newTagNames = tagNames.Where(n => !allTags.Any(t => t.Name == n)); foreach (var tagName in newTagNames) { // ... } ...and this worked fine, except that it failed to deal with cases where there's a tag called "Foo" and the list contains "foo". In other words, it wasn't doing a case-insensitive comparison. I changed the test to use a case-insensitive comparison, as follows: var newTagNames = tagNames.Where(n => !allTags.Any(t => t.Name.Equals(n, StringComparison.InvariantCultureIgnoreCase))); ... and suddenly I get an exception thrown when the foreach runs (and calls MoveNext on) newTagNames. The exception says: Sequence has no elements I'm confused by this. Why would foreach insist on the sequence being non-empty? I'd expect to see that error if I was calling First(), but not when using foreach? EDIT: more info. This is getting weirder by the minute. Because my code is in an async method, and I'm superstitious, I decided that there was too much "distance" between the point at which the exception is raised, and the point at which it's caught and reported. So, I put a try/catch around the offending code, in the hope of verifying that the exception being thrown really was what I thought it was. So now I can step through in the debugger to the foreach line, I can verify that the sequence is empty, and I can step right up to the bit where the debugger highlights the word "in". One more step, and I'm in my exception handler. But, not the exception handler I just added, no! It lands in my outermost exception handler, without visiting my recently-added one! It doesn't match catch (Exception ex) and nor does it match a plain catch. (I did also put in a finally, and verified that it does visit that on the way out). I've always taken it on faith that an Exception handler such as those would catch any exception. I'm scared now. I need an adult. EDIT 2: OK, so um, false alarm... The exception was not being caught by my local try/catch simply because it was not being raised by the code I thought. As I said above, I watched the execution in the debugger jump from the "in" of the foreach straight to the outer exception handler, hence my (wrong) assumption that that was where the error lay. However, with the empty enumeration, that was simply the last statement executed within the function, and for some reason the debugger did not show me the step out of the function or the execution of the next statement at the point of call - which was in fact the one causing the error. Apologies to all those who responded, and if you would like to create an answer saying that I am an idoit, I will gladly accept it. That is, if I ever show my face on SO again...

  • Installing software after .wim image

    - by lross1309
    I have been looking all day into how to install software to a .wim image. I have a .wim image of a laptop that will be deplyed to 20 more. The image is pretty much good to go except I need to add a couple more drivers and a couple more applications. Is there a way to do this in the answer file? Do I have to deploy the image, install the drivers/application, sysprep, and recapture the image? Any information relating to this will be greatly appreciated. Leon ps I have only been using answer files and imagex. Would like to stick with this for the time being. I plan on using WDT and WDS when I have some time to learn about it.

  • Swapping 3Ware Raid Card - Best Procedure

    - by Brian Lee Jackson
    We have a server running an old firmware version and driver (just took this position) on the 3Ware 9650SE Raid Controller... We have been having issues with the server and seemed to have narrowed it down to the Raid Card... I will be replacing the Raid card with the same model of 3Ware 9650SE, however, the card ordered most likely will have newer firmware on it. I managed to backup all the data to a very large drive. My plan is to update the firmware/driver on the current setup (which is still booting) and verify that everything works.. Then throw in the new Raid Card, check the firmware version (not letting it post). And update to newest firmware if needed via Java management utility on the card? Is this the best route? Thanks!

  • Spoof user agent for GoGo Inflight Internet?

    - by AndyL
    Is it possible to trick the GoGo Inflight WiFi on airlines into thinking that you have a mobile device instead of a laptop? It seems like most airlines that offer in flight wireless these days use GoGo. They offer different pricing for mobile and laptops. It seems like they are checking the browser's user agent. Out of curiosity, is it possible to use a Firefox extension like this one to spoof the user-agent and allow a laptop to access the internet under a GoGo mobile plan? How would GoGo handle something like an IMAP email client, like Thunderbird. Do IMAP clients have a user-agent field as well that would normally identify whether the mail client is running on a laptop or mobile device?

  • Shared SQL Server 2008

    - by nazaf
    Hi, I have a Windows Hyper VPS plan with 1024 MB of RAM. After installing SQL Server 2008 Express, my memory usage went up to 75% without running my site yet. I know that SQL Server consumes a lot of memory, so I decided to host my DB on a shared server. Which of the following is more scalable: install my DB on my VPS, or on a shared server ? If the latter, then can you recommend me a good shared server? Thanks.

  • Dump output from REPL

    - by Ankit Soni
    I'm writing SML programs, and I'd like a way to quickly see the output from running a program in the REPL without actually running the REPL (to quickly see if a program has syntax errors - I plan to use this as a make program for .sml files in vim to view the output inside vim).. Currently, I have this: sml file.sml | echo -e "\004" So it runs the program, and then echoes Ctrl-D to exit the REPL. The problem is that its too quick to send the Ctrl-D key, so there is no output. I tried this too: sml file.sml | sleep 2 ; echo -e "\004" But that isn't doing it either. Any ideas on how I can get a dump of the output from the REPL?

  • How to keep Windows 7 from sleeping while scanning the PC.

    - by D Connors
    So, I've been using Microsoft Security Essentials lately. And it usually takes a couple hours or more for it to full scan my hard drive. Because of that, I commonly leave it scanning while I go do something else. Problem is: 10 minutes later, windows 7 goes to sleep, and the scan is (obviously) paused. That's What I'd like to stop happening. So far, the only way I've been able to avoid it was to create a power plan, and switch to it while away, to keep the PC from sleeping. Problem is that I have to keep switching power plans and I'd like the PC to be able to go to sleep in case MSE finishes scanning and I'm still not back. Maybe I'm just asking for too much, but I've been surprised by the users here plenty of times already. So let me know if you know how to keep the PC from sleeping while MSE is scanning. Thanks

  • database on SSD: data only or the DBM program too?

    - by simone
    I plan on moving the data I use for statistical analysis (100-ish Gb) onto an SSD. The data is either sqlite single-file db's, or postgresql-managed data. The SSD is 240 Gb, 550 MB/s read and 520 MB/s write. Should I reserve that space for the data only, or would it be a good idea to install the operating system (Mac OS X) and the application directory (Adobe Suite, Microsoft Office and the like) on the SSD too? And would it make a substantial speed difference whether I also install the postgresql binaries on the SSD? I have plenty of other space (another 300Gb hard-drive, and a 1Tb one). Don't know the features of the non-SSD drives, though they're our standard equipment on all Macs, and they're definitely OK. Thanks.

    I'm planning to host a website where in the first phase I would target 30,000 users. It is in php and runs on Apache server. I'm assuming 8,000 users can be online in worst case scenario and 1000 of them will be uploading photographs. A photograph will be resized to around 1MB at client side and one HTTP request is uploading only one photograph. My plan: 2 Small EC2 instances to run Apache httpd 2 Small EC2 instances to DB (Postgresql). I to write data and other its read replica. EBS volumes for DBs Last, Amazon S3 for uploaded photographs. My question here Is Small EC2 instance more than what I require. I mean should I go for micro Is 8000 simultaneous user a right no. (to decide what EC2 instance to choose) for a new website Or should I go for Small instance so to make it capable of spikes

  • Hosting discussion forums on Windows 2008 Server / IIS, what software to use?

    - by Lasse V. Karlsen
    A plan to look into hosting discussion forums related to our product, on our own servers, has arisen, and I can't seem to find any pure .NET or Windows-based discussion forums. Since we're a pure Windows-based company, installing something that requires MySQL or Linux is going to require administration knowledge we don't currently have. What are our options? Every site I find that shows how to set up discussion forums on IIS involves just taking one of the many LAMP-based ones and tweaking IIS to run PHP or similar to run it. Isn't there a .NET-based discussion forum software? Free or not doesn't matter at this stage, right now we're just looking for options.

  • Episode by episode DVD Rip to AVI.

    - by ProfKaos
    I'm looking for a tool to rip DVD files to AVI files. VidCode looks cool, but it wants to convert the whole DVD (all files in the VIDEO_TS folder) to one AVI. I would like to pull each episode on the DVD to its own AVI. Is their a way to that with VidCode, or another ripper? My Plan B for VidCode is to manually separate files for each episode into their own VIDEO_TS folders. Is this possible? Is there an easy, lazy way to automate this?

  • Reboot VPS by reaching memory limit

    - by Ali
    When a server uses memory more than available RAM, the system will shut down the virtual machine. Then, it is only possible to boot from outside (VPS control panel, e.g. vePortal or SolusVM). However, it should be possible to plan a reboot before possible shut down. What is the best practical method to check the used memory, and reboot the system upon reaching e.g. 90% of the allowed RAM? Is there a common program or script to do so? I am using Debian/Ubuntu.

  • Changing Recovery Model in Replicated Database

    - by Rob
    I now am the proud owner of two servers that replicate with each other. I had nothing to do with the install, but (of course), now i have to support the databases. Both databases are in the Simple recovery model, but the users want to ensure as little data loss as possible so I'm thinking that I should change the recovery model over to full and start doing transaction log backups. I wasn't planning on backing up the subscribing database, only the publisher. Is this the right plan? Do I need to switch both the Subscriber and and the publisher to Full, or can I leave the subscriber in Simple, but have the Publisher in Full? When I change the recovery model in one (or both) do the databases need to be offline? Thanks

  • How to create a Linux Media Server using Ubuntu?

    - by Thomas
    Hello all: I'm an intermediate Linux user and a relative beginner to servers. I would like some help finding resources on setting up a basic server. I have Googled, and am a member of the Ubuntu Forums, but just figure it can't hurt to ask the Stack Overflow community for help as well. I plan on installing on an old laptop (Lenovo Thinkpad R61i or Toshiba Satellite A105). I have downloaded the latest Ubuntu (9.10) but don't know how to do any of the configurations. I just want a server to store my files where I can access (download and/ or stream) from a browser. Any help you can give is greatly appreciated. Thanks! Thomas
