  • Notepad++ find string with a new-line and replace

    - by Giraldi Maggio
    [Notepad++ Question] How do I use find-and-replace to replace the attribute of a series of tags using expression? Case scenario: Let's say I have a couple of lines of something like this: <li><a title="Bla bla" href= "http://www.url.com/etc">Text</a></li> And I want to replace them with this: <li><a title="Bla bla" href="">Text</a></li> Note the new line and double tabs on the original.

  • What's the reason to break HDD to few partitions for MDADM+LVM2?

    - by archer
    I'm using 2 HDDs each 1TB in size. I'm going to create MDADM+LVM2 over them. Initially I though about this partition layout: /dev/sda1 - 1Gb (boot) /dev/sda2 - 500Gb (md0) /dev/sda3 - 499Gb (md1) /dev/sdb1 - 1Gb (boot) /dev/sdb2 - 500Gb (md0) /dev/sdb3 - 499Gb (md1) md0 is going to be raid0 and md1 is going to be raid1 however, I found some info that this would be better to break each drive to more partitions (lets say 10 partitions 100Gb in size each). What's the reason of doing that?

  • How to optimally configure memcache running on 16 cores 144G ram server?

    - by Ivko Maksimovic
    Memcache is the only important app running on the server Server has 16 cores and 144G RAM Memcache is given 135G Memcache runs at 32 threads Gigabit network, test shows at least 300Mbit/s availability on network port 600 connections 3000 requests per second Say that memcache (memory) usage is at 50% - it's definitely not full As we increase number of requests towards server, requests slow down (from 8ms to 100ms per request) but server load remains 0.00. We suspect this can be solved by adjusting configuration but we don't understand many of the configuration parameters (besides, maybe, the number of threads). Any ideas?

I would like to know what will happen to the Luns that belong to the SG ..in my opinion they will remain in the SG as unassigned Luns ..or is there a possibility that the lUns will move back to the storage.

  • Firewall - Preventing Content Theft & Rogue Crawlers

    - by drodecker
    Our websites are being crawled by content thieves on a regular basis. We obviously want to let through the nice bots and legitimate user activity, but block questionable activity. We have tried IP blocking at our firewall, but this becomes to manage the block lists. Also, we have used IIS-handlers, however that complicates our web applications. Is anyone familiar with network appliances, firewalls or application services (say for IIS) that can reduce or eliminate the content scrapers?

  • Wondering about the Windows 7 serial number my laptop has, and its uses.

    - by overmann
    So that's the serial number of my pre-installed windows copy, I take it. But am I allowed to use it again when, say, I don't know, my system gets crippled by a sneaky virus? If I format my computer and install windows starter again from a USB drive (speculating. I've never format before, I suppose is completely possible) Is that serial number still valid? I'm talking about the number printed on the back of my laptop.

  • Building a video wall with devices

    - by machunter
    I am entertaining building a video wall made out of many android devices. But I have to say I have no clue about how to go about it? The fact that these are android devices is not very important I am curious about the general approach to doing video walls with many separated devices. At best the desktop of one machine should be displayed on all the devices. If not I would be also interested in just showing just a video on that wall.

  • Is it possible to run several virtual machines each with independent mouse+keyboard on a single PC?

    - by chiurox
    My goal is to instead of buying 4 separate basic PCs (plus the obvious peripherals), buy just one fast PC and the peripherals. I'm wondering if I can use a more powerful computer, say, one with core i7 and plenty of RAM, with 2 video cards (total of 4 monitor outputs) to run 4 or more virtual machines (WinXPs) so instead of having 4 individual machines, I'll be having just one. However, the catch is, is it possible to have a pair of mouse and keyboard + input/output audio for each of these virtual machines?

  • Wireless N extend G range?

    - by Sam
    I've searched all over the internet for an answer to this and I can't find one. If I purchase a wireless N router, with greater range than my current G router will the range of the wireless G signal go as far as the wireless N signal? I say this because Wireless N routers are supposed to be compatible with wireless G devices. Is the wireless G a lesser signal coming out of the router? Sorry if I confused you, I am a little confused myself.

  • Security camera for HQ and remote sites?

    - by Atlas
    We want to install security cams at HQ site and 3 remotes sites. Basically: (1) Each site would have N cams (2) Each site should have DVR locally to record everything. What we want is that HQ to be able to see the live/recorded videos of each remote site and including itself. Preferably HQ would have 1 large screen, and display all cams of itself and remotes sites, say showing it in 32x32 cells. Does such system exists?

  • How can I record system sounds (apps) in Audacity?

    - by Alex
    Or another similar program? All I want to do is record the sounds coming from say firefox, or any other app, for use as samples in music. I need to do this in both windows and linux (ubuntu 9.10). I have looked through the preferences of audacity but didn't find anything that let me select the system sound. Perhaps I overlooked it, because I was able to do this with earlier versions of audacity.

  • How to prevent a Windows 7 PC from sleeping when CPU usage is over X%?

    - by MaxVT
    I often leave the PC running into the night to process video files, so it shouldn't sleep while it's working but it would be nice if it went into sleep when it's done. During the export the CPU is always above a set %, and when idle it's typically in the single digits. Is there some tool or setting that would prevent the PC from going to sleep as long as the CPU usage (let's say averaged over one minute) stays above a specified limit?

  • Lazy linux backup system?

    - by Alex
    Ok, so I want to say Time Machine, but that's note exactly what I'm looking for. I want to set up a system that will regularly (hourly?) back up the /home directory of our machine. time Machine style things are naturally preferable since they save space by only saving the changes, but honestly, this is important enough that I can suffer some waste. Any ideas?

  • How to disable automatic and forced fsck on disks in a linux software raid?

    - by mit
    This is the /etc/fstab entry of a raid system /dev/md4 that is controlled with mdadm and webmin on an ubuntu 10.04 64 server: /dev/md4 /mnt/md4 ext3 relatime 0 0 We tried to switch off automatic forced fsck on rebotts, as we prefer to implement our own scheduled fsck routine by setting the last parameter of the line to 0 (ZERO). But we found out the forced and automatic check still occurs on the underlying real disks, lets say sdb1 and sdc1. How can we switch that off?

  • Rule of thumb in RAM estimate for static pages? [closed]

    - by IMB
    Possible Duplicate: How do you do Load Testing and Capacity Planning for Web Sites I've seen tutorials saying they can run decent websites on 64MB RAM (Debian/Lighttpd/PHP/MySQL) however it's not clearly defined how much hits/traffic a "decent" site gets. Is there a rule of thumb on how much RAM a web server needs? To keep things simple, let's say you're running a site with static content and it's averaging at 100,000 hits per hour (HTML + images combined, no MySQL). How much RAM is the minimum requirement for that?

  • I want to press a key combination in OpenBox and have a terminal appear below my resized Chromium window

    - by Erik
    This is one of those things that looks like it might have a simple solution but is rather time consuming once you start investigating PyTile, Xnee and the likes. I know, I should just use a tiling window manager etc., but I suppose it can be done in OpenBox, and I am just hoping somebody already has a working solution. Ok, so I want to press a key combination while I am in an OpenBox session (Lubuntu LXDE to be more precise) and have my terminal appear below my then resized Chromium window (say ~60% Chromium and ~40% Terminal).

  • What sites/publications are good for staying current on security and malware trends?

    - by Holocryptic
    In my ever expanding quest for knowledge, I'm at the point where I feel like I need to be more up to date with the current security trends, as well as malware and such that are in the wild. I'd like to be able to say, "I've heard of that and the fix is...." versus, "Oh, yeah, I had that eat up half my network before I contained it...." What sites and publications are good for keeping up with these things?

  • Network connection on Linux

    - by Kevin
    A general question about network connection on Linux : once a network connection goes into time_wait, is it still tied to the process ? Does it still use resources like say filehandle ? Reason I ask is because once it goes into time_wait, lsof does not report it anymore. I guess that means that the network connection is no longer tied to the process and hence does not count against filehandle limit. Would like to confirm though.
