How can I change the first byte of multiple files in Linux? Willing to use perl/awk/sed/whatever. Must work correctly on binary files (i.e. not change any other bytes).
I'm now monitoring multiple servers (3) and in the coming weeks that'll increase (towards 5 or 6). I've been keeping three terminal windows open running htop via SSH and I'm now wondering if there are any downsides to having a connection constantly open to production servers?
Is this still a bad idea? I know older versions of MySQL performed poorly with NFS. I imagine the issue lies with the usage of fsnc() and/or O_DIRECT. If the issues are mostly resolved, are there common pitfalls/gotchas, specifically around a large (multiple tables with tens of millions of records) InnoDB database that may see up to 20-50 reads/sec
I am trying to remove all the properties\personal information from a set of media files in a bunch of different folders. So far the only way I have found is by clicking into each folder, selecting all files and doing the process manually like this.
Does anyone know of any free apps, or scripts that can do this across multiple file locations?
I run a website on Windows Server 2008 R2. Looking through the IIS logs, I have noticed that there are some IP addresses repeatedly requesting certain URLs (such as for example /mysql/phpmyadmin/main.php, /phpadmin/main.php) which do not exist, as the site is entirely served off of ASP.NET. They are obviously fishing for known vulnerabilities.
My question is, are there any firewall or other tools (Windows built-in or commercial) that allow me to block those IP addresses which request certain URLs multiple times?
I am trying out a method to implement IP-aliasing on an Apache server.
Host multiple SSL sites on a single network card with IP aliasing
I have followed all the steps, but when I browse to my second domain I always end up in my primary domain.
Have anyone tried this method and is this even possible?
I want split a file into multiple files with at most 25 lines each.
I'm using this:
split -l 25 /etc/adduser.conf /home/ubuntu/PL/trab3/rc_
But I do not get the files I expect.
How can files with the filenames like rc_01, rc_02, etc.?
Is there a good plugin or codec that allows Media Player/Media Center on Windows 7 to play Apple Lossless (ALAC) encoded files? As the files are shared between multiple iTunes installations and one Media Center I don't want to transcode them. Bonus points for proper meta data parsing. :)

I am using the following code to make a single pdf file with multiple pages in one jpg file
I am using Imagick library and PHP tcpdf
convert -append path1.pdf path2.jpg

Can anyone help me out
I'm trying to create a way of opening a set of project files in multiple apps, using Alfred.
I know about the File Group extension in the powerpack (I have this), but as far as I can see, there's a limitation in that it only opens the files with the default app.
My usage case is this:
Open a .html file with Chrome
Open the same .html file with MacVim
Anyone know a way around this? Maybe an applescript is more what I'd need?
Are there software that lets you upload videos to video hosting sites (youtube,googlevideos, megavideo, etc)? with features like scheduling upload, queuing of videos to upload, multiple sites to upload. etc.
Any software with similar capabilities would be a help.
Thanks!
I have a document with multiple footnotes, some of which continue from page to page. The footnote separator has been customized for both 'continues on next page' and continues from previous page. However, on 1 particular page, the separator shows saying the footnote continues from previous page, but a brand new footnote follows. Is there a way to edit/delete the separator on 1 particular page only? (Word 2007)

I have a NFS mounted directory, and I'd like to monitor the I/O usage on it (MB/s reads and writes). What's the recommended way to do that ?
This is the NFS client, I don't have access to the NFS server.
I'm not interested in general I/O usage (otherwise I would use vmstat/iostat).
It also has multiple NFS mounts, I'm interested in monitoring just one specific mount (or I might have used ethereal).
Thanks!
When working from Windows, I prefer to use RoyalTS instead of the default Microsoft RDP client, because it allows me to save multiple connections, the credentials of the connection, etc; as well has having more than 1 connection open at a time.
Is there a similar (or any) alternative to the Microsoft RDP client for connecting from OSX to Windows? Aside from VNC, that is; at this point I'm hoping to continue using the RDP protocol.
I'm looking for a simple caching (can be caching-only) DNS server, which can do parallel resolving on its own. Is there something like that available?
Alternatively I know there's the c-ares library, which can do multiple-hosts resolution, but it's not a drop-in replacement for libresolve that I could use in the affected software. Maybe there is some other lib which can fulfill this requirement?
I know I can control access to programs in Terminal Services (TS) via 'Software Restriction Policies.' But is there a way to show only the programs relevant (i.e. accessible) to the TS user -- something akin to multiple profiles in a regular XP/Vista workstation?
Thanks.
I am running a desktop with Vista.
At random points when typing I will press a key, the key will stick. I will get multiple keypressesssssssssssssssssss. (for example what just happened at the end of that last word!)
Any ideas what is causing this? I dont even know where to start looking here..
Hi
I have a traditional telephony system at home. I also got an voip ATA device connected to the telephone socket. On a normal phone you can just plug it into the wall socket then multiple people on different phones can speak a the same time. Currently for me to take this call whoever answered the call will forward it onto my internal number. Is there not a way I can make it work like the analogue system so I can just pick up the phone?
After going through a few rdp sessions to xp machines, when I come back to my local machine it appears some setting has been tripped so every key I type is registered as one of the function/alt keys plus the key I type, causing windows to open and close windows randomly and other erratic behavior. Pressing windows key and numlock returns everything to normal. Any ideas what causes this. I have experienced this on multiple win 7 machines, but never in vista or xp.
Do I really need to split the single file into multiple files first? Shouldn't there be a one-step utility that lets you burn a CD and define track points at the same time?
Feeding off of this post.
I have a domain with Dreamhost and i've purchased SSL certificate for it.
I am moving over the server files to Linode but and setting the DNS in dreamhost to point over.
Linode provides a ip but it's not dedicated.
What is going to happen to SSL on that dreamhost IP when I switch over the DNS to linode?
I have one virtual host can I host multiple domains while using SSL for one?
I'd like to get some feedback about a migration From Apache to nginx. My goal is to reduce the memory footprint of the web server. Currently, I use the following modules.features on Apache:
multiple virtual hosts
Server Side Include
Fast CGI
Please share your experience: problems during migration, benefits after migration (was it worth it?), useful modules for nginx, etc.
I have a large file I want to transfer using either Internet storage hosting, DVD-Rs or USB storage, which sometimes is limited to FAT file-systems (for example: mobile phones)
What I'm basically looking for is a tool that create multiple files/volumes (less than 2GB each - FAT's file size limit) which are packed with a self-extracting executable.
Currently the only tool I found doing this is WinRAR, but that's shareware, and not free.
Is there any Free, preferably Open-Source tool that does that?
Thank in advance
