This is mainly for if you've done something silly like trying to clone a Live, running VM image. In this example, the VM initially finds grub and tries to boot but is kicked straight into initramfs rescue mode/busybox right after this.
If you've done this "silly" thing, you could have dataloss but a lot of times just using fsck will fix it as you are guaranteed at best to have some corruption and inconsistencies in the filesystem. My theory is that some files wer........
First we need a few extra packages:

dpkg -i grafana-enterprise_10.3.1_amd64.deb

Bonding is an excellent way to get both increased redundancy and throughput. It is similar to the "Network Teaming" feature in Windows.
There are a few different modes but we will use mode 6, I think it's the best of both worlds, as it is not just a failover, but it provides round robin, so you will get redundancy and load balancing. So if you have a 1G single port, you will have a combined throughput of 4G at this point. Just bear in mind that the true thr........
How To Install Wazuh Server / Quickest Installation
Wazuh (forked from the well known OSSEC project) is a full SIEM (Security Information Event Management) that works extremely well with the platforms it natively supports as an "Agent", which allows you to do scans of everything such as all processes running, CVE vulnerability check, incident reporting etc...
Prerequisites:

How To Compile QEMU Manually (using sensible options)
1.) Download the QEMU source file you want.
wget https://download.qemu.org/qemu-4.2.0.tar.xz
2.) Extract The Source File
tar -Jxvf qemu-4.2.0.tar.xz
3.) Switch to the extracted source
cd qemu-4.2.0
4.) Make sure we have the right libraries and tools to compile QEMU manually

myisamchk can fix it
But be careful and use the right options to avoid losing data. In fact if you haven't you should make a backup or at least manually copy /var/lib/mysql.
Replace "YourDB" with the name of your database
Replace "yourcrashedtable" with the name of your crashed table.
The -o option is the safest and should avoid dataloss whereas -r is more aggressive and is a last option (I have lost data using -r and........
Intel NUC J3455 vs Vorke V1 J3160
Both are excellent units but the J3160 is nicer if you require even lower power usage (6W vs the Intel 10W). The price is attractive on the Vorke V1 as well. It's been said that the Intel J3455 NUC has a buggy BIOS and some other issues that require attention.
The Intel J3455 is still nice because it has 2 RAMslots but it does get hotter due to lack of fan.
The Vorke V1 runs cooler, uses less power an........

Here is the scenario you or a client have a remote machine that was installed as a standard/default minimal Centos 6.x machine on a single disk with LVM for whatever reason. Often many people do not know how to install it to a RAID array so it is common to have this problem and why reinstall if you don't need to? In some cases on a remote system you can't easily reinstall without physical or KVM access.
So in this case you add a second physical or disk or already ha........

This is a great way to test and experiment without risking your current table, or to make a backup of your current table to avoid corruption or dataloss due to malicious activity eg. deletion etc..

I backed up everything in the /mnt/sd_card directory thinking that some dataloss could occur for some reason but purposely left my microSDHC unbacked up thinking that "it won't touch that since it's external" and Samsung's and other manufacturers website even say this (that it won't be affected and not to worry etc).
Apparently I was wrong, my microSD was "undetected" and asked to be formatted after the upgrade (there goes 3-months worth of family photos). No........

This is obviously a bug in the r8169 kernel module and it seems to affect a lot of people. I upgraded to the latest kernel and hope this won't happen anymore, as it is a very serious error. This is especially serious for those who are running servers with this chipset, who can afford for the NIC to randomly go off-line for no apparent reason?

FreeBSD Desktop OSsI would probably choose these over Linux.
In many ways these are probably more stable and just as easy to use as any Linux distros but the benefit of stable, updated and secure packages!

Personally PC-BSD is Beta at this point and is not easy if you are installing it on a non-primary partition.

Everything was working fine but I believe when Iturned off "EDGE" in Big Boss everythign went haywire, at first my WiFi dropped, then 3G didn't work and I couldn't even make phone calls.

Yes, Iadmit I finally got bitten by the hype as much as I can usually see through it all. Keep in mind this review is of the "stock" phone, no jailbreaking yet which is what really unleashes the customizability and whyI bought iPhone.
I had better things to say about this phone before buying it, and it is a great phone, perhaps the best on the market by far, if not because of the Mac OS port onto the iPhone and all the apps, etc, etc.
With that said........
As much of a computer nerd as Iam, I'm usually a late adopter to technology for a few reasons. Ifeel most new hyped technologies and electronics are mainly fads, and I'm also cheap.
Adopting later means you avoid the bugs, kinks and most importantly pay the lowest price, that's me being cheap again :)

When trying to even cd or ls the mounted OCFS2 partition it crashes. Ithink this is a combination of VMWare Server's problem and the way I mounted and symlinked to it.
More than anything this shows the problem and lack of forsight with VMWare, but also that OCFS2 is easily crashed if you do strange things.
