• Is it possible to dump the names of all the open files in notepad++ to a file?

  - by mark

  So, I dragged and dropped multiple files onto notepad++. The files came from different directories and were selected using different criteria. So, I have many files open in Notepad++. Now I need to have a list of all the open files in another file. Right now, my only option is to script the decisions used to guide me in selecting the files in the first place. Which is probably the best in the long term, but I wonder if there is a quicky one in Notepad++. Some plugin magic or whatever. Suggesting another free editor which has this function is a good option too (not that I am going to ditch notepad++, God forbid)

• How to rename multiple files in multiple folders with 1 command

  - by Charles

  We want to rename our *.html files to *.php but (sadly enough) have not enough knowledge to do it with a dos batchfile and/or cmd prompt command. The problem is that each file is in seperat folder and yes talking about 1500+ different folder names. Using wildcards for the files I know is the '*' but using also a wildcard for folders is unknown to me. We probably need to use the (MSDOS) 'FOR' command but there I am stucked. Folder structure we use is: parent-folder/child-folder/grandchild-folder/file.html sample: games/A/game_name/file.html, games/B/game_name/file.html, games/C/game_name/file.html and so on. The parent folder is for all files the same, the child & grandchild folders are different for most files. After renaming these files to .php I assume following in the .htaccess will make a permanent redirect. RedirectMatch 301 (.).html$ http://oursite.com$1.php Looking forward to suggestions/answers, thnx in advance.

• Why does Excel now give me already existing name range error on Copy Sheet?

  - by WilliamKF

  I've been working on a Microsoft Excel 2007 spreadsheet for several days. I'm working from a master template like sheet and copying it to a new sheet repeatedly. Up until today, this was happening with no issues. However, in the middle of today this suddenly changed and I do not know why. Now, whenever I try to copy a worksheet I get about ten dialogs, each one with a different name range object (shown below as 'XXXX') and I click yes for each one: A formula or sheet you want to move or copy contains the name 'XXXX', which already exists on the destination worksheet. Do you want to use this version of the name? To use the name as defined in destination sheet, click Yes. To rename the range referred to in the formula or worksheet, click No, and enter a new name in the Name Conflict dialog box. The name range objects refer to cells in the sheet. For example, E6 is called name range PRE on multiple sheets (and has been all along) and some of the formulas refer to PRE instead of $E$6. One of the 'XXXX' above is this PRE. These name ranges should only be resolved within the sheet within which they appear. This was not an issue before despite the same name range existing on multiple sheets before. I want to keep my name ranges. What could have changed in my spreadsheet to cause this change in behavior? I've gone back to prior sheets created this way and now they give the message too when copied. I tried a different computer and a different user and the same behavior is seen everywhere. I can only conclude something in the spreadsheet has changed. What could this be and how can I get back the old behavior whereby I can copy sheets with name ranges and not get any errors? Looking in the Name Manager I see that the name ranges being complained about show twice, once as scope Template and again as scope Workbook. If I delete the scope Template ones the error goes away on copy however, I get a bunch of #REF errors. If I delete the scope Workbook ones, all seems okay and the errors on copy go away too, so perhaps this is the answer, but I'm nervous about what effect this deletion will have and wonder how the Workbook ones came into existence in the first place. Will it be safe to just delete the Workbook name manager scoped entries and how might these have come into existence without my knowing it to begin with?

• Strange Phantom Local Disks appearing in my drive list...

  - by Paul

  Win7 Home Prem 32 bit I seem to have several phantom Local Disks mapped to different letters, they are of 0 bytes in size? Strangely they do not show up when i view my drives through windows explorer but if i open an application such as ACDSee Pro or MS Word and then go to open a file i can see all these Local Disks mapped to different letters. This means when i plug in my external hard disk it ends up mapped to letter R instead of its usual G which messes up any programs i have pointing to it by default. How did they get there and more importantly how do i get rid of them please??

• How do I transfer videos from DV camera to divx?

  - by Ward

  I have a videocamera that uses mini-dv tapes. In the past, I've transferred the files and made DVDs, but that was time- and disk-space- consuming. I wanted to find new tools and to figure out how to convert the videos to something smaller like divx but I didn't know enough about all the different formats to answer a previous question. Well, now I've done a bunch of research and I understand some of the details of video encoding, and in the process I wrote up some notes on the different formats involved in going from a DV videocam to divx or H.264 They're a bit rambling, but in case it's of any use, I'm going to post them as an answer. I'd be very interested in anyone else's answer as well.

• Apache httpd.conf handle multiple domains to run the same application

  - by John Stewart

  So what we are looking for is the ability to do the following: We have an application that can load certain settings based on the domain that it is being accessed from. So if you come from xyz.com we show a different logo and if you come from abc.com we show a different logo. The code is the same, running from same server just detects the domain on the run Now we want to get a dedicated server (any suggestions?) that will enable us to point all the doamins that we want to this server (we change the DNS for the domains to that of our server) and then when the user goes to a certain domain they run the same application. Now as far as I can understand we will need to create a "VirtualHost" in apache to handle this. Can we create a wildcard virtualhost that catches all the domains? I am not an expert with Apache at all. So please forgive if this comes out to be a silly question. Any detailed help would be great. Thanks

• How can I set Qmail to relay all mail to one address

  - by MoSiAc

  I'm new to qmail it's setup and working like it should. I need to set it to do something a bit different. I need it to take all mail that would be incoming to it and relay all of that to one address as opposed to whatever address they could have possibly set it to. The idea is we have setup a test enviroment and we want no e-mails from a test server to actually go out to real people so this relay server will catch all of that outgoing mail and throw it into a test e-mail account inbox to check for errors and so forth. I'm honestly not sure if this is even possible so if it's not let me know now so I can come up with a different method to manage all these test e-mails. Thanks

• How can I figure out which PHP extensions aren't being used?

  - by Tom Marthenal

  I manage a server (running Ubuntu) which hosts our client's sites with a few dozen different PHP-based websites, mostly small sites but also some installations of CMSes and forums. I used the get_loaded_extensions() method to see what extensions I have loaded. To help streamline the server (remove unnecessary extensions to make upgrading easier and marginally improve speed), I'd like to remove extensions that aren't being used by any of the sites. I currently have 54 different extensions loaded. I can easily eliminate some of these from the list which I know are used, but others I am less sure about. Is there some way that I can see extensions which have not been used recently?

• Terminal, vim and ssh color problem

  - by xaph

  I'm using vim for my editor. I've problems about the colors of vim. The same colorscheme of vim gives different outputs in terminal, ssh session and screen. I learnt they've different colors(16, 88 or 256). I don't care of using 16 color or 256 color. Also the terminal emulator is not very important to me. My questions: 1- How do I use same vim colorscheme with same output on everywhere? 2- I want to write a color definition and use it every terminal(maybe with Xdefaults file). Is it possible?

• Windows 7 Intermittent Connection Issues (Continuously "identifying")

  - by andrewktmeikle

  I have an issue solely with my desktop windows 7 machine on my network (the network has multiple different devices, on the same and different operating systems) and the issue is that irregularly, although sometimes frequently, I briefly get disconnected from the internet (briefly is for around 5-10 seconds). However, I never loose the bars on the wifi thing, eg I don't get the yellow triangle, but it goes to the identifying stage and then reconnects. The reason I noticed the problem was when I was streaming music it would stop and I would refresh the page and it would start working again ( turned out it was because it took that amount of time to get connected again). So my question is, what would cause the intermittent issues and start the "identifying" process again. I don't think its my router, because no one else is having problems, so the other option is that its a problem specifically with my machine. I'm connecting to a Netgear DG834GT router, and I'm using a Edimax Wireless-N150 USB Adapter. Anyone have any ideas?

• UTF-8 locale portability (and ssh)

  - by kine

  I spend a lot of my time sshed into various machines, all of which are different (some are embedded, some run Linux, some run BSD, &c.). On my own local machines, however, i use OS X, which of course has a userland based on FreeBSD. My locale on those machines is set to en_GB.UTF-8, which is one of the available options: % echo `sw_vers` ProductName: Mac OS X ProductVersion: 10.8.2 BuildVersion: 12C60 % locale -a | grep -i 'en_gb.utf' en_GB.UTF-8 Several of the more-capable Linux systems i use appear to have an equivalent option, but i note that on Linux the name is slightly different: % lsb_release -d Description: Debian GNU/Linux 6.0.3 (squeeze) % locale -a | grep -i 'en_gb.utf' en_GB.utf8 This makes me wonder: When i ssh into a Linux machine from my Mac, and it forwards all of my LC_* variables with that 'UTF-8' suffix, does that Linux machine even understand what is being asked of it? Or is it just falling back to some other locale? In either case, what is the mechanism behind its behaviour, and is it dependent on any particular set-up (e.g., will i see the same behaviour on a BusyBox-based system as on a GNU-based one)?

• Is it possible to know a user logged in on Ubuntu instantly?

  - by Mustafa Orkun Acar

  In fact, I am trying to restrict access to some websites for different users. I asked the question: Restrict access to some websites for different users. The given answer is ok; but as the owner of answer says, it works if users are locally logged in. That is; if the user logs out and logs in, restrictions are no more valid. So, I decided to run a script including the iptables commands for restrictions at every log in event. I want to know whether it is possible to know instantly the user logs in.

• Route global shortcuts to pages opened in Firefox

  - by zamza

  I like listening to music online on sites like stereomood.com. There is a major problem, however. I can not control the player with my keyboard. And even with a mouse - when I want to play/pause I must activate firefox window, select the tab where music plays and hit play/pause button manually - this is a pain, especially when you play a fullscreen game that can not minimize itself. Thus said, global keyboard shortcuts would be a perfect solution. I understand that different online media players have different controls and each site must be configured individually (like, select button with id 'play' and press it), but I believe that can be done in principle. I also guess that such tricks are impossible without some third-party native app which captures shortcuts and routes them to Firefox window. So, any solutions? Maybe some AutoHotkey hacks or similar.

• Good speedtest results, but web pages don't load

  - by dmt0

  I have strange connection problems. Ping and download times are good - speedtest.net showed ping 65ms and download 2.17Mbps. Torrent is working well, giving me up to 300MBps. Webpages are loading very poorly though. They are timing out each time - I'd have to refresh 4-5 times to get any simple page to load. It has been happening consistently for the last few days. Same with different browsers on different machines (same network), Windows and Linux. There is no proxy in the browser. Is there any setting in Windows or in a browser that I can change to help this? Some background: I live on this island in Thailand, where internet connection is through radio to another island and than to mainland - it's very weather dependent, but generally OK. As I mentioned, ping is good. Any input is very appreciated.

• Python: how to calculate data received and send between two ipaddresses and ports [closed]

  - by ramdaz

  I guess it's socket programming. But I have never done socket programming expect for running the tutorial examples while learning Python. I need some more ideas to implement this. What I specifically need is to run a monitoring program of a server which will poll or listen to traffic being exchange from different IPs across different popular ports. For example, how do I get data received and sent through port 80 of 192.168.1.10 and 192.168.1.1 ( which is the gateway). I checked out a number of ready made tools like MRTG, Bwmon, Ntop etc but since we are looking at doing some specific pattern studies, we need to do data capturing within the program. Idea is to monitor some popular ports and do a study of network traffic across some periods and compare them with some other data. We would like to figure a way to do all this with Python....

• Load-balanced Linux server across internet?

  - by LinuxGnut

  I'm investigating setting up a load balanced server solution consisting of three CentOS 5.4 boxes. Two of these boxes will reside in one facility, while a third will reside in a different facility. I'm currently working to set up heartbeat, ldirectord, ipvsadm to load-balance the machines, but I'm not sure its going to work with I'm not overly familiar with the details behind how all of these work, but is the load balancing going to work correctly when these servers are not all on the same LAN? I'm not sure if heartbeat is using SNMP to send signals or not, which would only work over a LAN. Has anyone tried this or found a different solution?

• When load balancing, must all copies of static web page be exactly the same?

  - by Gilles Blanchette

  I am used to get answers for everything on the web, but not this time... Yesterday I enable Amazon DNS weight functionally to load balance 7 websites between two different IP addresses (split 50%-50%). Both servers run IIS 8.5, sites runs well on both sides. Today I found out that Google WebMasterTools is reporting fails error with file robots.txt, all close to 50% of access try errors. The robots.txt file is ok and accessible (even via Google testing URL page) on both servers. Lets say current version of static web pages are on the first computer and the updated version of the same web pages are on the second computer. Can it be the problem? When load balancing, can static web pages be slightly different from one host server to the other? Thank you for your help

• Copying large Windows directory structure to new server with permissions intact

  - by Chris

  I'm soon going to be doing a large migration of an old-school web server that serves mostly ASP pages (currently on a Windows 2003 server) to a newer, virtualized Windows 2008 server. This new server is going to be in a different domain, as well. So I'm copying the root web folder, and all its subfolders and files, to this new server. I'd like to keep permissions intact. It's also pretty massive - I'd like to be able to compress it before transferring to the new server with permissions intact. Any way to do that? And will the new server being in a different AD domain screw with my plans?

• Tcp window size won't go above 130048

  - by Roger

  I have 2 servers set up with about 80ms latency between them. Both are centos 6 and run a java app that transfers data from on location to another. Both are on 1gbps connections. I have been trying different sysctl settings and different send & receive buffer settings in java but no matter what I set them to, I cannot get the tcp window size to go above 130048 in the tcp dumps. This equates to roughly 13mbps which is the actual throughput I am getting.

• Which SSL certificate to buy [closed]

  - by Sparsh Gupta

  I am reading several notes on SSL certificates and comparison. What matters to me the most is speed. I can read that encryption is same with all different certificates available but I was wondering if there is any difference in the performance of the website with different certificates involved. I am ofcourse interested in end to end response times and I wonder if the type of encryption or number of certificates required as Chain Certificates makes a difference in speed. I dont really care for cost but looking for a good SSL certificate which ideally gives me absolutely no pain and best performance. Recommendations?

• Setting up linux server with multiple access rights

  - by Mark

  I am a graduate student and want to set up a linux server (preferably Ubuntu) in my office. I also want to give my friends SSH access to that box. My question is can I set up my server such that I can give one of my friends rights to install software on my machine but he cannot brows around outside the directory he is allowed to? Can I set up multiple apache instances (on different ports) for different people? so each has access to their own apache instance?

• Getting console2 to work nicely with UAC

  - by Merlyn Morgan-Graham

  I would like to get console2 to work nicely with UAC Particular problems I would like to tackle: If I start non-elevated, have a way to elevate while running. It'd be especially nice if I could elevate individual tabs I would like to get different coloring for admin/non-admin, similar to: this link. Basically, if I can get the console to execute a command on startup (similar to the HKLM\Software\Microsoft\Command Processor\AutoRun registry value), that's all I need How do I get this working? Would I have to modify source code to get this to work, or can I use different tab settings/do hacks w/ shell executables? I am using Windows 7, although I would imagine any working solution would also work on Vista.

• Should I choose KVM/XEN over OpenVZ or use them together?

  - by Krystian

  I've got a dual xeon e5504 server, with [for now] only 8GB of ram. Storage is'n impressive either: 3x 146GB sas in raid5 + 500GB sata drives. Currently it works as a development server, but it's over speced for our needs and since our development methods changed through last 2 years we decided it will work as a production system for some of our applications + we would like to have a separate system for testing/research. Our apps are mainly web apps deployed on tomcats [plural as some of the apps require older versions] and connected to Postgres. I would like to have a production system, where only httpd+tomcat+db are setup and nothing else runs there. Sterile system. Apart from that, I would like a test system, where I can play with different JVM settings, deploy my test apps, play with tomcat/httpd settings and restart them without interfering with the production system. Apart from that, I would like to be able to play with different linux flavors, with newer kernels to test how they work etc. I know, this is not possible with OpenVZ and I would have to choose KVM for that. I am thinking about merging the two, and setting up a KVM to be able to work with different systems [linux only to be frank] + use openVZ to setup separate machines for my development needs. I would simply go with that, but reading here and there about the performance impact full virtualization has over containers and looking at the specs of my server makes me think twice about it. I don't want to loose too much performance, especially because of the nature of my apps [few JVMs running at the same time]. It will be my first time with virtualization, apart from using desktop virtualbox/vmserver. Although I am a fast learner I don't want to mess with the main system so much that it will break the production apps or make them crawl. Although they are more or less internal apps and they don't produce much load, they need to be stable. I've read, that KVM host is a normal linux installation and it allows to run normal processes on it. If that is so, does it allow to run openVZ as well? I mean... can I have KVM and OpenVZ running on the same system/kernel? Or do I have to setup another system to run OpenVZ containers? How much performance impact can this have for me? Will my hardware suffice? oh and one more thing... unfortunately I'm quite limited with the funds... I'm looking for a free solution only :/

• Best practice for administering a (hadoop) cluster

  - by Alex

  Dear all, I've recently been playing with Hadoop. I have a six node cluster up and running - with HDFS, and having run a number of MapRed jobs. So far, so good. However I'm now looking to do this more systematically and with a larger number of nodes. Our base system is Ubuntu and the current setup has been administered using apt (to install the correct java runtime) and ssh/scp (to propagate out the various conf files). This is clearly not scalable over time. Does anyone have any experience of good systems for administering (possibly slightly heterogenous: different disk sizes, different numbers of cpus on each node) hadoop clusters automagically? I would consider diskless boot - but imagine that with a large cluster, getting the cluster up and running might be bottle-necked on the machine serving the OS. Or some form of distributed debian apt to keep the machines native environment synchronised? And how do people successfully manage the conf files over a number of (potentially heterogenous) machines? Thanks very much in advance, Alex
