  • How to find all occurences of an email address on a website

    - by thomasrutter
    Let's say I have a large website which may have a number of email addresses on it that are getting picked up by spammers. I plan to obfuscate or remove them all. What's the easiest way to crawl my website to find any email addresses I may be exposing? Either through on-page text (which Google can pick up, but not very well) or mailto: links (which Google can't).

  • Under what circumstances would a junction point be more appropriate than a symbolic link?

    - by Benjamin Pollack
    Symbolic links were introduced an incredibly long time ago in Windows, yet I still encounter a large number of systems that use junction points. I know that symbolic links afford functionality not in junction points (e.g., they work on external drives); my question is whether there is functionality specific to junction points that make them more appropriate than symbolic links in some circumstances.

  • Make Emacs status bar draggable anywhere?

    - by Ken
    In Emacs, if I split the frame (C-x 2), each window has a status bar. Historically, I could drag the status bar to resize them. Unfortunately, with Emacs these days and just a few modes (for version control, line/col number, abbrevs, my programming language, etc.), pretty much the entire bar has remapped mouse-1 to something other than letting me drag the bar! Is there any way to turn the status bar back into something I can drag, without losing all of my modes?

  • SQL Clustering on Hyper V - is a cluster within a cluster a benefit.

    - by Chris W
    This is a re-hash of a question I asked a while back - after a consultant has come in firing ideas in to other teams in the department the whole issue has been raised again hence I'm looking for more detailed answers. We're intending to set-up a multi-instance SQL Cluster across a number of physical blades which will run a variety of different systems across each SQL instance. In general use there will be one virtual SQL instance running on each VM host. Again, in general operation each VM host will run on a dedicated underlying blade. The set-up should give us lots of flexibility for maintenance of any individual VM or underlying blade with all the SQL instances able to fail over as required. My original plan had been to do the following: Install 2008 R2 on each blade Add Hyper V to each blade Install a 2008 R2 VM to each blade Within the VMs - create a failover cluster and then install SQL Server clustering. The consultant has suggested that we instead do the following: Install 2008 R2 on each blade Add Hyper V to each blade Install a 2008 R2 VM to each blade Create a cluster on the HOST machines which will host all the VMs. Within the VMs - create a failover cluster and then install SQL Server clustering. The big difference is the addition of step 4 whereby we cluster all of the guest VMs as well. The argument is that it improves maintenance further since we have no ties at all between the SQL cluster and physical hardware. We can in theory live migrate the guest VMs around the hosts without affecting the SQL cluster at all so we for routine maintenance physical blades we move the SQL cluster around without interruption and without needing to failover. It sounds like a nice idea but I've not come across anything on the internet where people say they've done this and it works OK. Can I actually do the live migrations of the guests without the SQL Cluster hosted within them getting upset? Does anyone have any experience of this set up, good or bad? Are there some pros and cons that I've not considered? I appreciate that mirroring is also a valuable option to consider - in this case we're favouring clustering since it will do the whole of each instance and we have a good number of databases. Some DBs are for lumbering 3rd party systems that may not even work kindly with mirroring (and my understanding of clustering is that fail overs are completely transparent to the clients). Thanks.

  • Mysql innoDB corruption after server crash

    - by Ward Loockx
    Yesterday my server died because an outage in the data center. Today it's back up, but having some problems with mysql. First of all my mysql server was not able to start. For this reason I deleted the files ib_logfile0 and ib_logfile1 in /var/lib/mysql folder (I still have the old failing files). After this my server was able to startup again. But now I see a lot of issues in the mysql log file. Sep 1 09:43:55 * mysqld: 120901 9:43:55 InnoDB: Error: page 70944 log sequence number 8 1483471899 Sep 1 09:43:55 * mysqld: InnoDB: is in the future! Current system log sequence number 5 612394935. Sep 1 09:43:55 * mysqld: InnoDB: Your database may be corrupt or you may have copied the InnoDB Sep 1 09:43:55 * mysqld: InnoDB: tablespace but not the InnoDB log files. See Sep 1 09:43:55 * mysqld: InnoDB: http://dev.mysql.com/doc/refman/5.1/en/forcing-recovery.html When I check the docs on mysql.com, I found that I need to recover my database with backups. I have a backup but not sure what's the good way on importing it. Or is there a way to recover without having to re-import the database again? So if I'm correct I need to put innodb_force_recovery to 4 in mysql and delete all current data and re-import? Is there a way to do this without having downtime? I also have one slave running. This slave has the current status now: Last_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master's binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave. How can I totally reset the slave after the new import on the master has happend? Hopefully we can find a solution without not to much downtime. Thanks!

  • Raid1 with active and spare partition

    - by Daniel Baron
    I am having the following problem with a RAID1 software raid partition on my Ubuntu system (10.04 LTS, 2.6.32-24-server in case it matters). One of my disks (sdb5) reported I/O errors and was therefore marked faulty in the array. The array was then degraded with one active device. Hence, I replaced the harddisk, cloned the partition table and added all new partitions to my raid arrays. After syncing all partitions ended up fine, having 2 active devices - except one of them. The partition which reported the faulty disk before, however, did not include the new partition as an active device but as a spare disk: md3 : active raid1 sdb5[2] sda5[1] 4881344 blocks [2/1] [_U] A detailed look reveals: root@server:~# mdadm --detail /dev/md3 [...] Number Major Minor RaidDevice State 2 8 21 0 spare rebuilding /dev/sdb5 1 8 5 1 active sync /dev/sda5 So here is the question: How do I tell my raid to turn the spare disk into an active one? And why has it been added as a spare device? Recreating or reassembling the array is not an option, because it is my root partition. And I can not find any hints to that subject in the Software Raid HOWTO. Any help would be appreciated. Current Solution I found a solution to my problem, but I am not sure that this is the actual way to do it. Having a closer look at my raid I found that sdb5 was always listed as a spare device: mdadm --examine /dev/sdb5 [...] Number Major Minor RaidDevice State this 2 8 21 2 spare /dev/sdb5 0 0 0 0 0 removed 1 1 8 5 1 active sync /dev/sda5 2 2 8 21 2 spare /dev/sdb5 so readding the device sdb5 to the array md3 always ended up in adding the device as a spare. Finally I just recreated the array mdadm --create /dev/md3 --level=1 -n2 -x0 /dev/sda5 /dev/sdb5 which worked. But the question remains open for me: Is there a better way to manipulate the summaries in the superblock and to tell the array to turn sdb5 from a spare disk to an active disk? I am still curious for an answer.

  • Windows 7 Update shows no updates in list

    - by svinto
    My Windows Update keeps telling me that I have 3 (put your random number here) important updates to install. However, when I click on them, the list that pops up is empty. I can still install the updates, but I cannot see and of course also not decide which updates are going to be installed.

  • How to sync bookmarks across Google Chrome and Mozilla Firefox bookmarks?

    - by ViliusK
    How to sync bookmarks across Google Chrome and Mozilla Firefox bookmarks? As I, currently, understand, Google Chrome puts bookmarks seperatly from Google Bookmarks, which is accessible in Firefox by using Google Toolbar for Firefox. Right? So how should I synchronize my browsers? I use Google Chrome as my primary browser and it works good and bookmarks are synchronized across number of computers I'm using. Thanks, viliusk

  • image filter that spits out pi

    - by patrickinmpls
    I've seen this before but I forgot what's its called. Does anyone know of software that takes a picture and spits out an image of the number pi, ie. 3.14... not the symbol? It basically kinda looks like ascii art but the numbers are different shades of gray so it is like a black and white photo. Thanks!

  • LPR on Windows: Can you specify # of copies?

    - by Bill
    In Linux, you can use lpr -#5 foo.txt to get 5 copies of a document when sending to an LPD-based print server. The Windows (XP, 2003, 2008) version of LPR supplied by MS doesn't seem to have this option, though. Does anyone know if there's a hidden option to specify the number of copies? Thanks.

  • Automatically restarting Perfmon Data Collector Sets

    - by Scott Herbert
    I have a number of User Defined Data Collector Sets running on a Windows 2008R2 server, collecting perfmon stats from various servers. Whenever there is a network interruption, or a server rebooted (at worst, when the server which is running all these DCSs is rebooted), I have to manually restart some or all of the Data Collector Sets. Is there a way to configure them to automatically restart, or otherwise be more resilient?

  • Safari Plugin/Extension Sites?

    - by Kaji
    Useful as it was when I was running Tiger, the number of broken links and general lack of information on what's compatible with version 4.0+, I've decided it's time to give up on PimpMySafari.com and look elsewhere. Can anyone recommend a similar site that actually keeps its content up-to-date?

  • Adding FreeBSD user upon first login

    - by Halik
    Is it possible, to achieve the proposed behavior on my FreeBSD 8.2 server: New user ssh's into my server. He supplies as 'Login:' his student index number and a new, locked account is created with random password that is sent to his [email protected] mail as authentication method. After he logs in with this password, account is fully created and activated/unlocked and the user is asked/forced to change the pass for a new one.

  • creating iTunes listing INCLUDING "Where" information

    - by Hugh
    Although iTunes produces a very good comprehensive listing of all music which can be copied and pasted into excel to give a database of music, unfortunately it does not include"where" information as shown on the "Get Info" summary. As, in my own case, music files are in a number of different locations(drives and folders) I would like to be able to identify, quickly and simply,duplicate tracks as the last column in the excel listing. Is there a way to do this?

  • display values within stacked boxes of rowstacked histograms in gnuplot?

    - by gojira
    I am using gnuplot (Version 4.4 patchlevel 2) to generate rowstacked histograms, very similar to the example called "Stacked histograms by percent" from the gnuplot demo site at http://www.gnuplot.info/demo/histograms.html I want to display the values of each stacked box within it. I.e. I want to display the actual numerical value (in percent and/or the absolute number) of each box. How can I do that?
