  • How do I insert a newline within a long formula using OpenOffice.org Math?

    - by Lekensteyn
    I've the following formula: (x^6+x^4+x^2+x+1)(x^7+x+1) = x^13+x^11+x^9+x^8+x^7+ x^7+x^5+x^3+x^3+x^2+x+ x^6+x^4+x^2+x+1 = x^13+x^11+x^9+x^8+2x^7+x^6+x^5+x^4+2x^3+2x^2+2x+1 Putting this in OpenOffice.org Math causes every line be concatenated, which I want to avoid. I've already tried putting newline between the lines, but it adds a strange question mark in the formula. Using matrices did not work for me either. I want to achieve a nicely formatted formula like this one (taken from FIPS 197 pdf):

  • Puppet, Nagios, Munin on cPanel based hosts

    - by WinkyWolly
    I've been managing 20-30~ cPanel based hosts over the past year with Puppet, Nagios and Munin for general monitoring / trending however a lot of the methods I've had to use to deploy / manage things such as configurations a pain. For those of you who aren't familiar with cPanel - it adds a few things to yum exclude such as perl*, ruby* and so forth. This causes issues with me being able to bootstrap monitoring on a new server via Puppet (well via the Package type) due to a bunch of conflicts with installing via Yum. Now I could create a custom RPM for everything and remove certain dependencies from the spec file however I would like to avoid this if possible. Does anyone have any proposed functional ways to manage this sort of environment? Currently I install Puppet, Facter and Munin via RPM's and force install using --nodeps and such (since they're installed, just no the ones Yum wants). Nagios I installed manually from source at this time (likely will create RPM's however I want to tackle this general issue first).

  • Should I be running my scheduled backups as SYSTEM or as the our domain admin?

    - by MetalSearGolid
    I have a daily backup which is scheduled through the Task Scheduler. It failed with a strange error code last night, but I was able to search and find a blog post with how to avoid the error in the future. However, one of his recommendations was to run the backups as the Administrator user of the domain. Since all of the files being backed up are local to this system, should I continue to have the backups run as SYSTEM? Or is it actually better to run it as a different user? I have been running these backups for well over a year now and have only had a handful of failures, but ironically when it does fail, the error code means it was a permissions issue (or so I read, this code seems to be undocumented by Microsoft). Thanks in advance for any insight into this. Might as well post the error code here too, in case anyone would like to share their insight on this as well, but I rarely ever get this error, so I don't care too much about it: 4294967294

  • Windows 7 Professional N needs to be just Windows 7 Professional.

    - by Jess
    I have a laptop at work that originally had Windows 7 Home Premium on it. We have a tech that comes in a few times a week to do some of our support work, and we asked him to upgrade the laptop to Windows 7 Professional. Before he left he told us the upgrade didn't work and that we'd have to order a disk. Upon checking the computer it seemed he had upgraded to Windows Professional 7 N. It had not previously been Home Premium N, so I'm not exactly sure how he managed to upgrade it to an N edition. I do not understand why he didn't run the Any Time Upgrade, but that is now irrelevant. How can I change Professional N to regular Professional? I would like to avoid having to restore it back to Home if possible.

  • associate dhcp requests with subdomains in dnsmasq

    - by Dezra
    I have dnsmasq running as a dns server with a number of linux boxes using static ips that run several virtual hosts on subdomains. I currently have the following address line in my dnsmasq.conf to map the subdomain of a boxes address to the boxes static ip: address=/.devbox1.mydomain.com/192.168.1.3 address=/.devbox2.mydomain.com/192.168.1.4 e.g. site1.devbox1.mydomain.com > maps to devbox1 static ip, site1 virtual host site2.devbox1.mydomain.com > maps to devbox1 static ip, site2 virtual host site3.devbox2.mydomain.com > maps to devbox2 static ip, site3 virtual host I was wondering if I can change the machines over to DHCP addresses (instead of static) and have dnsmasq use the dhcp ip instead of the static one? Can I modify the address line to refer to the DHCP address (obviously, I cant hardcode the address)? I know I could add mac address to ip allocation, but I want to avoid this if possible.

  • How/where to find all Update (msu) packages for Windows 7 (Enterprise)

    - by Rudi
    Hi, I've been using Wim2Vhd to create native boot vhd files. (I'm using this to keep several development environments ready, I'm a developer, I know -- I need help ;-) Now the first boot always ends up in several minutes installing all of the windows updates... I' know I could avoid this if I had a massive list of qfe (.msu) packages that I could supply to the command line of Wim2Vhd. Where can I find all of the updates so I can download them. I have found this: http://www.megaleecher.net/Downloading_Microsoft_Windows_7_Offline_Updates but I'd like a more official source and I'd like an easier way to download them all. I'm a developer, so if I find the information (web service?) to get all the current packages, I'll build a tool to download them to a single location and generate a list of them for use with Wim2Vhd.

  • How to find date/time used by Cassandra

    - by JDI Lloyd
    Earlier this morning I noticed that one of the nodes in our Cassandra cluster is writing logs an hour in the future, despite the date/time being correct on the OS. A couple of other nodes I checked via logs appear to be writing logs at the correct time. I now need to go through and check each node in our 80 node cluster and ensure cassandra is running on the correct time, problem being is some of the nodes don't write to the logs very often as they aren't doing much... the question is, is there some form of tool/utility (ie nodetool) that can tell me the time that cassandra is running on? All the systems date/times are correct, ntpdate cron in place has been for a while. Servers are set to Belize timezone to avoid DST changes so its nothing to do with that.

  • Problems serving SVN over HTTPS on Ubuntu 10.04

    - by odd parity
    We've been experiencing some problems with our Subversion server after upgrading to Ubuntu 10.04. When trying to access a repository, regardless of client (I've tried git-svn and svn on Windows as well as svn on Ubuntu 10.04, from different computers and network locations), I get a 400 bad request. Here's the output from svn: svn: Server sent unexpected return value (400 Bad Request) in response to OPTIONS request for 'https://svn.example.org/svn/programs' Here are the relevant entries from the Apache logs (I'm running Apache 2.2): error.log [Mon Jun 14 11:29:31 2010] [error] [client x.x.x.x] request failed: error reading the headers ssl_access.log x.x.x.x - - [14/Jun/2010:11:29:28 +0200] "OPTIONS /svn/programs HTTP/1.1" 401 2643 "-" "SVN/1.6.6 (r40053) neon/0.29.0" x.x.x.x - - [14/Jun/2010:11:29:31 +0200] "ction-set/></D:options>OPTIONS /svn/programs HTTP/1.1" 400 644 "-" "SVN/1.6.6 (r40053) neon/0.29.0" If anyone has run into similar problems or could give me a pointer to track down the cause of this I'd be very grateful - I'd really like to avoid having to downgrade the box again.

  • Is this a normal operating temperature range for a New Third-Generation MacBook Air (2.13 MHz, 120 G

    - by doug
    Even with just my text editor open (no web browser) and maybe the terminal, the baseline temperature is usually above 40 C. When i open 4-5 browser tabs in Safari (even if none of Sites have Flash) the temp can quickly go over 50 C. (In addition, i am observing these temps even though i have turned the fan up to 3000 rpms). (i have install smcFanControl on my MBA so i can see the temp in the menu bar.) So this means my MBA is running much warmer than my MBP; and in practice, it means that i have to be very careful how i use my MBA. Of course if i load a Site with Flash, it just freaks out, and often quickly goes above 65 C (I've installed a flash blocker to avoid this). Is anyone else observing this behavior? I have checked the Apple boards and sure enough, there are a lot of complaints, but nothing from Apple.

  • Is there a way to communicate DBMS with raw memory block or binaries

    - by darkcminor
    I am trying to communicate a numerical matrix operations library like LAPACK with any DBMS. Is it possible to send/receive complete matrices as binary or as a direct memory pointers to process them (it will be something like: The Outside library processes data stored in DBMS, then it computes some huge matrix stuff and then via memory block or a binary DBMS get the result from library)? The main purpose is speed and avoid passing through a flat file, and last but not least, use library toefficiently do some operations DBMS are not designed to. * Is it possible that Oracle, SQL Server, MySQL support this technique?.

    Let's assume we have two Windows XP computers with identical hardware configuration, including GPRS modem connected to COM1 serial port. On the first PC we add new modem device, set up gprs connection on this port in "Network connections" folder. How avoid clicking the same procedure on second computer? Detailed questions: Where are the entries from "Network connections" stored? File, registry? Is there a possibility to clone such entry between PCs? Question as above but regarding modem entry in device manager - can it be exported from one pc and imported on second?

  • How to increase the disk cache of Windows 7

    - by Mark Christiaens
    Under Windows 7 (64 bit), I'm reading through 9000 moderately sized files. In total, there is more than 200 MB of data. Using Java (JDK 1.6.21) I'm iterating over the files. The first 1400 or so go at full speed but then speed drops off to 4ms per file. It turns out that the main cost is incurred simply by opening the files. I'm opening the files using new FileInputStream (and of course closing them in time to avoid file leaks). After some investigating, I see that Windows' disk cache is using only 100 MB or so of RAM although I have 8 GiB available. I've tried increasing the cache size using the CacheSet tool but any values I provide are considered out of range. I've also tried enabling the LargeSystemCache registry key but (after rebooting) the CacheSet tool still indicates I'm using 100 MB of cache (and doesn't increase during the test run). Does anybody have any suggestions to "encourage" Windows 7 to cache my 9000 files?

  • MySQL on Windows - how do I set the wait_timeout for connections using named pipes?

    - by gustafc
    I use a MySQL database running on a Windows box, and for performance reasons I'm connecting to it using named pipes. The (Java) application using the database (through Hibernate) can let the connection lie idle for quite a long time, which causes the connection to fail with the following message: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 33 558 297 milliseconds ago. The last packet sent successfully to the server was 33 558 297 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. autoReconnect unfortunately has no effect (and neither does autoReconnectForPools), but the wait_timeout docs state that wait_timeout only applies "to TCP/IP and Unix socket file connections, not to connections made via named pipes, or shared memory". How can I change the wait_timeout for named pipes?

  • Suscribers locking during snapshot replication

    - by remi_bourgarel
    Hi all :) Here is my architecture : I have a main server and 4 replica (the servers are synchronized with snapshot replication). The replication is working fine, except for one thing : during the replication a lot of SELECT request on one of the replica fail with a time-out. Here are my questions : Can I avoid these time-out ? If I can't : how can I detect the start and the end of the replication to redirect all the request on one of the replica to the main ? Thanks Sorry if you already answered to that kind of question but I couldn't find anything.

  • PuTTY/SSH: How to Prevent Auto-Logout?

    - by feklee
    My ISP's SSH server (Debian 2.0) logs me out after 35 minutes of inactivity, when connected with PuTTY (Windows XP). This is a big problem when I utilize the server for port-forwarding. The final messages displayed in the terminal: This terminal has been idle 30 minutes. If it remains idle for 5 more minutes it will be logged out by the system. Logged out by the system. PuTTY options that do not help: Sending of null packets to keep session active. Seconds between keepalives (0 to turn off): 30 [x] Enable TCP keepalives (SO_KEEPALIVE option) Any idea how to avoid the auto-log-out? Should I try another SSH client?

  • Mod_rewrite not working on ISPConfig 3 Server

    - by Akahadaka
    Problem I recently migrated a Drupal site from a shared hosting server to my own VM. Everything appears to work correctly, except clean urls. My VM Setup Ubuntu 10.04 LAMP ISPConfig 3 What I've tried From reading up on a number of drupal forums I've tried the following in this order Check that mod_rewrite is installed and enabled Changed PHP from FastCGI to Mod_PHP (prefer to use FastCGI or suPHP though to avoid having tmp/files folders with 777 permissions) Changed the Redirect type to L in ISPConfig Sites-domain.com-Redirect Changed /etc/apache2/sites-enabled/000-default <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride All ... </Directory> Not sure about points 3 and 4, I do want all domains to be able to use mod_rewrite out of the box. Question Have I done something wrong or am I missing a step? Ultimately I would like to use FastCGI and clean urls working on all ISPConfig 3 domains without having to make any changes to individual domain settings. Any ideas appreciated, I'll try them all.

  • Automate configuration change on Outlook 2007

    - by Julien Vehent
    I am migrating a bunch of mailboxes to google apps. Each user owns several mailboxes each serving different domains (john has [email protected], [email protected], and so on...) Currently, those accounts are hosted on (edit:NOT an exchange server) an old SMTP/POP server we want to replace, and I need to edit their outlook 2007 configuration to change the pop, smtp and password parameters. The hard way to do it is to connect to each outlook session and edit the parameters manually. I want to avoid that. Because that represents over 700 accounts spread between 40 users... :'( How can I automate this configuration change ? In the active directory ? Using a PRF file ? note: I'm a linux sysadmin with very little knowledge of windows's black magic.

  • SMTP server problem

    - by ram
    Hi, Our requirement is to send weekly newsletters to our website customers. For which we wanted to have local hosted SMTP server in our office. We are not using SMTP server provided by website hosting provider, as we wanted to reduce the network traffic and avoid IP blocking due to bulk mails. We are sending newsletters on weekly basis from our local SMTP server. But due to some reasons, some emails are going to spam and some are not reaching to customers and sometimes there are bounce messages to follow bulk email guidelines (mainly from Gmail). Can you please suggest me, how to achieve my problem. I also wanted to know what type of technology generally Linkedin or banks uses to send notifications emails to all its customers. When they send bulk emails, they will always reach inbox with out any problem. I want the same solution to implement for my website. Please suggest me. Thank you very much in advance.

  • capistrano still asks for the 1st password even though I've set up an ssh key???

    - by Greg
    Hi, Background: I've setup an ssh key to avoid having to use passwords with capistrano per http://www.picky-ricky.com/2009/01/ssh-keys-with-capistrano.html. A basic ssh to my server does work fine without asking for passwords. I'm using "dreamhost.com" for hosting. Issue - When I run 'cap deploy' I still get asked for the 1st password (even through the previous 2nd and 3rd password requests are now automated). It is the capistrano command that start with "git clone - q ssh:....." for which the password is being requested. Question - Is there something I've missed? How can I get "cap deploy" totally passwordless? Some excerts from config/deploy.rb are: set :use_sudo, false ssh_options[:keys] = [File.join(ENV["HOME"], ".ssh", "id_rsa")] default_run_options[:pty] = true thanks PS. The permissions on the server are: drwx------ 2 mylogin pg840652 4096 2010-02-22 15:56 .ssh -rw------- 1 mylogin pg840652 404 2010-02-22 15:45 authorized_keys

  • How can I fix this configure error?

    - by balor123
    I'm trying to build mosh from source on a SUSE10 machine and am getting the following error: checking for protobuf... no configure: error: Package requirements (protobuf) were not met: No package 'protobuf' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables protobuf_CFLAGS and protobuf_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. I downloaded the source to protobuf and installed it in a custom path as well. I'm not using a package manager for any of this and cannot for various reasons outside the scope of the question. I added that custom path to my PATH and rehashed. Typically, this is enough for configure but in this case its not doing the trick. I added the prefix for protobuf to PKG_CONFIG_PATH but am still hitting this error. What should I do next to get past this error?

  • Improving server security [closed]

    - by Vicenç Gascó
    I've been developing webapps for a while ... and I always had a sysadmin which made the environment perfect to run my apps with no worries. But now I am starting a project on myself, and I need to set up a server, knowing near to nothing about it. All I need to do is just have a Linux, with a webserver (I usually used Apache), PHP and MySQL. I'll also need SSH, SSL to run https:// and FTP to transfer files. I know how to install almost everything (need advice about SSL) with Ubuntu Server, but I am concerned about the security topic ... say: firewall, open/closed ports, php security, etc ... Where can I found a good guide covering this topics? Everything else in the server... I don't need it, and I wanna know how to remove it, to avoid resources consumption. Final note: I'll be running the webapp at amazon-ec2 or rackspace cloud servers. Thanks in advance!!

  • "Half" ssh authorization to a server with git repository

    - by hsz
    Hello ! Currently I have purchased web hosting with ssh access. I have created a git repository on it and if I set my public key in ~/.ssh/authorized_keys file, I have access to that repo, I can push/pull data, etc. This solution allows access for every user that has his public key in authorized_keys file. But there is one thing that I want to avoid. Every user can login to the server too and has access to whole ssh account. Is it possible to create a blacklist of users' keys that will not have an access to ssh ? I see it that way: user logs in to a git - ok, allow for every one user logs in to ssh account ~/.profile file is hooked and called a custom script: check user's public key if public key is in ~/.ssh/blacklist_keys call bash exit/logout Is it possible in any way ?

  • Prevent Ultrabay HDD from ejecting on sleep

This pop up is very annoying every time every time I use the computer. I don't want to disable write caching [D:Hardware[drive]policiesquick removal] because I want best performance and never remove the drive. Any ways to avoid this pop up?
