USB Camera in Windows 10 and Oracle VM!
I have a Logitech High Definition Pro Webcam for AV purposes connected via USB to the PC running Windows 10. After a recent update of Oracle’s Virtual Box to version 5 something happened to the Camera connection: I was unable to use the built-in microphone of the Camera for making internet calls.
This post is all about how I diagnosed the problem and solved it in about ten minutes.
Problem: Unable to access the USB Camera in Windows 10! Being unable to access the USB camera connected to my HP PC with Windows 10 operating system came as a surprize. It was an upgrade from Windows 8.1, most recently.
Solution: Because the Camera (well, for that matter, almost all USB devices) connected on this machine were enabled/connected to windows 2012 Virtual Machine via Oracle Virtual Box installed on this PC. This probably did not happen via the most recent upgrade. Probably, I had previously enabled them manually and forgotten about it!
This happened when I updated/upgraded the Virtual Box to version 5. The reason for this upgrade was that the previous version did not provide “bridged adapter” to connect my guest operating systems to the internet directly to the Modem. It was only allowing me to do NAT or Virtual Box only network connection which were insufficient. They did not fulfill my expectations.
So, after disconnecting those USB devices from the virtual machine, I was able to access camera, printer, and scanner on windows 10 PC directly!

If sixth graders grasp this, what is wrong with our politicians?
Seattle, Washington, one of the strongest remaining bastions of liberal philosophy left in the country, passed a phased-in $15 minimum wage law earlier this year. The highest minimum wage in the country. The vote was unanimous and the throng outside cheered, but for many this is a loss from which they will never recover. It is a blow to the profitability of businesses that they just can’t take.
According to the National Review Hotline, Kathrina Tugadi owner of Seattle’s El Norte Lounge, no longer hires musicians for her restaurant, she said she can’t justify expenses that don’t directly “add to the bottom line.” And, she says, hours will have to be cut: El Norte Lounge plans to stop serving lunch and only serve dinner.
“I am concerned about my business and others in the community, but it isn’t just about any one business. It’s about how the entire economic community,” she said. El Norte may be unable to remain open once the ordinance is fully in effect, she said. Even Pagliacci Pizza, a Seattle-area pizza chain, is considering moving its call center and some of its production facilities outside the city. That’s a lot of job loss, a lot of new people with a new wage of ZERO.
Socialist Council-member Kshama Sawant was the main proponent of the $15 ordinance. She and her supporters denied that the policy change would hurt businesses in the city. In one interview, Sawant said there need be “no unintended consequences.”
In Seattle, 42 percent of surveyed employers were “very likely” to reduce the number of employees per shift or overall staffing levels as a direct consequence of the law. Similarly, 44 percent reported that they were “very likely” to scale back on employees’ hours to help offset the increased cost of the law. That’s particularly bad news for the Seattle metro area, where the unemployment rate for 16- to 19-year-olds is already more than 30 percent — due in part to Washington state’s already-high minimum wage.
Perhaps most concerning about the $15 proposal is that some businesses anticipated going beyond an increase in prices or a reduction in staffing levels. More than 43 percent of respondents said it was “very likely” they would limit future expansion in Seattle in response to the law. One in seven respondents is even “very likely” to close a current location in the city limits.
Yes, it it always sounds good to give people more free stuff, but once again, everything has a price. I asked a group of sixth graders what they would do. It only took them a few minutes to determine that their only choices were to; fire some employees, raise prices, or go out of business. They also concluded that people won’t come to your store if you charge too much. If sixth graders grasp this, what is wrong with our politicians?
Seattle is the first city in the country to pass a $15 minimum wage. Survey results suggested it will be the first city to find out why it was such a bad idea.
Using “sed” on command line to search/replace only one instance of a word/phrase in a file.
First, get a list of occurrences of the word/phrase using cat and grep:
cat file.ext | grep “exact word or phrase including html/code”
Choose one complete phrase or line to do the change:
sed -i ‘s~old phrase including <code>~new phrase including <html>~g’ file.ext
Here is the official guide to install ffmpeg. This involves several steps. These instructions also apply to installing FFMPEG on your machine.
1. Adding a new repository to your list.
Download/install RPMForge package for your 32-bit machine : http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.i686.rpm
2. Downloading/Installing the necessary packages.
3. Enabling/disabling repositories.
Some more instructions from repoforge.org. Use as needed.
cat /etc/redhat-release to find which release of EL you are using
uname -a to find your processor architecture
rpm -ivh package-filename to install the rpmforge-release package (also works with URLs)
- You can use
curl to download the package using one of the above links if needed (for example on a server with no X Window)
- Then you can use
yum to install the available packages from the RepoForge repo, e.g.
yum install --enablerepo=rpmforge-extras
- Afterward, you can disable accidental updates from the repo by setting
enabled = 0 in the repo definition file in
4. yum search ffmpeg
5. yum install ffmpeg ffmpeg-* gstreamer-ffmpeg. If you use Virtualmin to provide/maintain your hosting/machine, make sure you have updated your system with ‘yum -y update’ before enabling rpmforge on the machine!
6. yum install mplayer smplayer mencoder
7. That’s it. Check it plays a DVD or video using SMPlayer from Applications -> Sound Video -> SMPLayer!
Please follow the link, Playing DVDs in a CentOS 64bit installation for steps for 64bit machines.
If you recently installed CentOS 6+ (Desktop) and if your Ethernet connections are showing up but not working, and getting this error”_nm_object_get_property: error getting ‘State’ for /org/freedesktop/NetworkManager/ActiveConnection/3: (19),”then follow the instructions below to correct the problem.First login to the machine directly as root or as a privileged user.1. Disable NetworkManager by running ‘service NetworkManager stop.’2. Enable network by running ‘service network start.’Now, check your internet connection by opening a well known website on the browser or try grabbing a random web page by running ‘wget domain.tld’ on command line or better yet, try updating your system by running ‘yum -y update.’Caution. Before running ‘yum -y update,’ make sure you have enabled/disabled needed/unwanted repositories. For more on repos, please visit, repos in CentOS.
Log in to your account/server as a privileged user or as root.
Type <ifconfig> which will display all your Ethernet/internet connections.
in the output, under the active internet connection, you will find your ipv6 address.
The repositories configuration files are located at “/etc/yum.repos.d/” in CentOS 6+
Run yum repolist to check for enabled repositories which will give you a list repo IDs and repo names:
Loaded plugins: fastestmirror, refresh-packagekit, security
Determining fastest mirrors
* base: mirror.stanford.edu
* centosplus: centos.chi.host-engine.com
* extras: mirrors.sonic.net
* updates: centos.mbni.med.umich.edu
repo id repo name status
base CentOS-6 – Base 4,802
centosplus CentOS-6 – Plus 62
extras CentOS-6 – Extras 12
updates CentOS-6 – Updates 831
virtualmin Red Hat Enterprise 6 – i386 – Virtualmin 101
virtualmin-universal Virtualmin Distribution Neutral 193
To permanently disable a repo, open ‘/etc/yum.repos.d/CentOS-Media.repo’ in a text editor like nano/gedit/emacs, go to the end of file and change ‘enabled=1’ to ‘enabled=0’
That’s it, you just disabled a repository on CentOS 6.5!
Enable automatic follow-up and install of needed modules.
1. open a cpan shell:
perl -MCPAN -e shell
2. enable automatic follow-up
o conf prerequisites_policy follow
o conf commit
Here is a one-liner from stackoverflow!
perl -MCPAN -e 'my $c = "CPAN::HandleConfig"; $c->load(doit => 1, autoconfig => 1); $c->edit(prerequisites_policy => "follow"); $c->edit(build_requires_install_policy => "yes"); $c->commit'
This is a very common and important question anyone could ask.
I think every person who works in IT secretly wants the, “No, I will not fix your computer” t-shirt. Anyone involved in working with PCs comes to dread the inevitable conversation, “Since you’re pretty good with computers, I’ve got this question.” I’m sure plumbers, electricians, and auto mechanics all have their own version of this scenario.Lately, the question I’ve been getting most frequently is the one that I dread answering the most. “You seem to know a lot about smartphones. I’m thinking about an Android or an iPhone. Which do you recommend?”You might think my answer would be pretty straightforward, but it never is. I’ve got a lot more hands-on experience than the average user on both Android and iOS platforms, including rooting, jail-breaking, and fixing bricked devices. I own an iPad, iPod Touch, and several Android devices. I know most people have to live with one platform or the other. This makes a recommendation very difficult to make.What seems like a simple answer is really a complex situation. Both platforms are nearly indistinguishable from one another in average, day-to-day use. Sure, there may be some features like Siri or Google’s navigation that could sway a user one way or another, but for most users, their actual experience won’t differ much.So, what guidelines can you use to help someone pick a phone that won’t have them coming back complaining that you steered them in the wrong direction? These points are usually where I start:1: Are you invested in Google environments already? 2: Are you a Windows or Mac user? 3: Do most of your friends have iPhones and other iOS devices, or do they have Android smartphones?4: Do you plan on using this device as a BYOD on your corporate network to access company email or other resources? 5: What is your experience with spam, viruses, and malware?For answers click the link below:
