Curious as to solutions to an LCD monitor making a high-pitched whine. The frequency of the whine changes based on refresh rate selections.
Can this be fixed? Time for new hardware? Other alternatives?
I want to teach my son to be a strong PC user. I could try to strike out on my own for this, but I was wondering if there is a good online (or book based) course for this.
Like most kids, he's proficient with Google, YouTube, and Minecraft, but he's very curious, and I would like to teach him more. Even some basic excercises, like working with the file system would be good for him (i would need some help to not make it boring).
I've got a cell that's using the CORREL function to return the correlation of two rows of data in my spreadsheet. The issue is that I'd like this to update based on the filter that I have applied.
I'm using the SUBTOTAL function to do this for other functions such as SUM and AVERAGE. How can I get my correlation function to do the same thing and respect the filter that I have applied?
I hope I am asking this at the correct forum. I have a client from whom I have developed a PHP based Facebook project, who is hosting their site on IIS with ASP and no access to PHP, so they have created a sub domain to point to my server to host the site. I have an SSL on www.mydomain.com, but their sub domain does not have SSL (app.theirdomain.com).
Would redirection from their side be possible to SSL on my side so that the FB app works?
Is there a way to monitor ec2 instances without using cloudwatch? I ask this since ec2 instances are basically VPS's, and using output from commands like top, vmstat, htop in scripts may not give the clear picture as the CPU cycles are shared between other instances as well.
What should one keep in mind while monitoring CPU usage on a VPS?, should one have alerts based on top load or % of CPU used by user processes coupled with other factors like processes waiting on disk io, hardware interrupts?
I have grow to prefer x86 based router OS's like Vyatta and pfSense over their competitors Cisco and Juniper (Well, I never really used Juniper, but still.). However, they feel "fake" to me, like "Frankenstein" routers. I think my greatest worry is that I am missing out on something by not using the main contenders.
Are there any benchmarks out there that compare the main metrics (throuput, etc.) of x86 router operating systems to their proprietary counterparts?
I'm currently trying to download a full magneto install from a ftp server. The connection keeps failing, it seems as if there are too many files and folders to scan through?
Can anyone shed any light on how to resolve this? The shared platform seems to b e a standard platform based on Plesk 8.6.
As this is a shared server, there is no option for me to really do anything, apart from contact the hosting company (who have offered to zip up all the files for me, but this is not ideal)
I am giving a lightning talk shortly and need to put together some slides. It is a technical talk about Perl documentation. I will be using a OS X machine to run the presentation software.
I would like something that is
minimalistic
easy to publish to the web
simple to control (forward and back should do it, but hotkey access to individual slides would be nice)
simple to create slides for (preferably purely text based and doesn't require much in the way of markup)
Hi, on Mac, you know there is no 'merge files' when you command+c/command+v some folder on another one, it actually replaces it. I'm simply wondering on what UNIX is this based? Because correct me if I'm wrong, but "cp - R" DOES merge files, no? And that's what I'm doing via the Finder, copying some files and folders...
thanks!
Is is know that Xen Server is based on CentOS, and it is fact that CentOS can be installed on an ISCSI target flawlessly, but I wanted to install Xen server on an ISCSI target I couldn't find a way.
I already tried the latest version of xen server 6.2, and there is no obvious way who to do the installation without a local disk.
Does anybody have an idea about the subject, or did someone know how to do it?
Please share your experience about this subject.
I seems i did some mistake, and installed Ubuntu server on my home based ubuntu box.
and the problem is that GRUB places the server edition as a priority boot in the menu, especially when I upgrade the kernel or the release.
How can I remove the server from the GRUB menu permanently? can I un-install Ubuntu server edition?
I run a small PBX based on the FreePBX distro of Asterisk. The installation has been steadily upgraded but for various reasons, we want to start again on a new server with a clean install from the distribution media.
Will I be able to take a backup from the old server and restore it to the new server, even though the installs are different versions? How sensitive are FreePBX backups to the build version? Is it possible to get at least a partial restore?
Hi all,
I have had a bunch of Linux based streaming servers that employed lighttpd web server to provide video streaming via port 80.
Recently, our service is very slow. Therefore, I would like to ask if there is a good software package that helps us monitor and record our bandwidth usage, lighttpd established connections, TCP sync connections, disk I/O ... over time.
Any suggestions?
Regards,
Dinh
With each new server comes at least one more daily crontab email. The FreeBSD servers even send two: a daily and a security run output. Thanks to my obsession with virtualisation the number of emails I need to read (and then often discard without further action) is becoming too much.
What ways are there to manage / automate this process? Can emails be replaced by something that is web based? Surely some of you must have found creative ways for this.
Hi,
I'm a pro user of vim, however, somehow I don't seem to have definitively figured out the use of time based undo, or maybe I don't really like it.
Is there a way I can undo a deletion caused by Ctrl-w
W3I will be really grateful for the help.
Thanks.
I am running a wsgi based application that has concurrent users accessing it. For my logs needs I tried logrotate but found that logrotate is not too friendly to Python applications, so I tried using RotatingFileHandler and even worse found my logs all chopped up and part of it went missing!
I am considering ConcurrentRotatingFileHandler, my question is, has anyone out there experienced the same thing and better yet do you have any battle tested solution for Python wsgi, concurrently accessed applications?

Hello,
A professor at the university asked me if I could install some software for him on his laptop that runs SLES 11. I'm not familiar with SUSE (I typically work with debian based machines) so I'm having some trouble finding/installing some software.
Here's the list of software he needs installed:
-xv (plotting software)
-xmgrace
-LaTeX
Can someone point me toward some rpms for the above-mentioned software?
I have a promotional DVD from a client, and they want to put clips from it on their website.
I'm in a Windows environment, so I'm looking for a decent video editor program, free would be preferred. Then I guess I'd have some kind of flash-based player to embed in the website...
What do you recommend?
I have several laptops so I use a USB key version of Firefox to keep my environment as I move around. I followed the suggestions offered on the Firefox web site (turn off the cache and history etc.) and its better but still much slower than the normal version.
Other than buying a new, super fast flux-capacitor based USB key, what other tips and tricks can I use?
I'm trying to use an old parallel-port based printer with a USB-to-parallel port adapter on Windows 7. When I plug it into the USB port on the computer it's listed as an unrecognized device. I know that these cables typically use the "USB Printing Support" driver with makes USB ports show up as printer ports in the printer dialog. Is there a way to manually add USB Printing Support to Windows 7, since it isn't being added automatically?
Is it possible to configure Google somehow to permanently ban search results from domains that I know 100% are never, ever going to make me happy? Something cookie/session based maybe?
E.g.: I want to ban (permanently, forever and always) results from experts-exchange.com. Every time I click results that take me to their page I just want to scream.
Shotwell helps me keep my photos organized. It would be nice if there was something similar for my videos. I prefer something Gtk-based, but I'm open to ideas.
I'm trying to find out whether VMware ESX 4.x Fault Tolerance (FT) is supported on a particular server and VMware's HCL is confusing me. It says that some servers with FT-supported processors (specifically the Xeon 3400 Lynnfield) do not support FT and some with almost identical specs (same chipset for instance) do support FT.
Could this be a mistake on the HCL itself? To my understanding FT support is based only on the CPU.
Thanks.
