You can't change bad IT by changing the OS.

I'll try to attend them all. Why not?

There's a topic here for spoken language with Duolingo, why not one for programming language, SoloLearn.

We can link up there as well and learn some basics on your choice of popular programming languages.

I started with PHP, and will move to JavaScript next I think. I will personally get the most use out of PHP, which is why I chose that one, as will never be building apps.

Install Veeam Backup
** Note ** Not yet supported on Fedora 26.

1. Download Veeam Backup Free here: https://www.veeam.com/linux-backup-free-download.html
   a. Use the Fedora 24 (or newer) download (not CentOS/RHEL).

2. Install Veeam Repository:
   rpm -ivh veeam-release-fc24-1.0-1.x86_64.rpm

3. Install Veeam Backup:
   dnf install veeam

4. To open/access Veeam Backup, type the following in “su” Terminal:
   veeam (see work-a-round first!)

5. Follow on-screen directions.

Fedora 26 Veeam (1.0.1.364) Issue Work-a-round

1. After installing Veeam, open and edit the following file:
   vi /usr/src/veeamsnap-1.0.1.364/snapimage.c

2. Comment out the following line and then save. There are two occurrences.
   .direct_access = NULL

3. Run the following command to rebuild:
   dkms install -m veeamsnap/1.0.1.364

4. Backing up with Veeam in Fedora 26 should now be functional.

It took me a little bit of digging, and I got lucky finding an easy solution:

su -c 'dnf install http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm'

dnf install ffmpeg-libs

Something to add here, as I just had to re-do a Hyper-V host... Pagefile.sys

I installed Hyper-V Server 2016, and it decided to put the pagefile on the MD1000. I wanted it on the drive. It took me a while to figure out how to do it via PowerShell, but I got it. Here's the PowerShell I used to fix it:

Set-WMIInstance -Class Win32_PageFileSetting -Arguments @{name="C:\pagefile.sys";InitialSize = 4096; MaximumSize = 12288}

Run that line and reboot.
I chose my page file size as such because the drive is small, and I don't care about page file. But MS recommends to use use as automatically managed, so there we go... a mid-way compromise.

You can check the status by running this:

Get-WmiObject Win32_PageFileusage

That VMQ thing can be an issue on 1 GB NICs with out-dated firmware/drivers. The info of affected drivers and NICs and the resolution can be found here:

https://support.microsoft.com/en-us/help/2986895/virtual-machines-lose-network-connectivity-when-you-use-broadcom-netxt

This is a good write-up and how to resolve it. Or you can just run firmware and driver updates.

VMQ should be disabled on 1 GB NICs. The issue with the broadcoms is that it's enabled by default, and shouldn't be.

I thought it was an interesting read.

@nets said in SQL Virtulization:

We ran across a server at a new clients that was installed in the last 6 months to host their MS Dynamics install. The system was installed as a physical server with 3 RAID 10's consisting of 4 drives each. The 3 array's are broken up for the DB, Logs, and Backup.

We want to conver the server to a VM and configure a large RAID 10 with all 12 drives. When doing this is it still necessary to have 3 VHDX's if they are going to be on the same array?

Why are vendors still installing on physical systems?

Yes, it is a good practice to to use several VHDXs.

Examples:

1. OS.vhdx
2. DB.vhdx
3. Log.vhdx
4. Backup.vhdx
5. Data/Apps.vhdx

There are a lot of benefits to doing it this way, depending on your environment. There really is no down side to doing it when it's a VM, only potential benefits.

Moon
2022-01-10

Well, because I won't have any clear nights for awhile and therefore cannot go out and see the stars, I thought I'd go back and see if I have any old Moon photos.

I found one from soon after I first got my telescope, learning how to use it. It will be nice to compare to the next time I capture the Moon in 2023 now that I've had some practice.

Setup:
I didn't get some of the image capture details, but this is what have:
5" SCT, Focal reducer/corrector, Fujifilm X-T4 @ ~787mm f/6.3 (I think, will update later)
PIPP + AS!3 + Lightroom

@manxam said in Windows 10 Performance tweaks:

@pmoncho : I have to ask: why? I understand if you're using Windows 8.1 or the first couple versions of Windows 10 with the weird start menu but with current revisions the start menu differs very little from Windows 7. Turn off the groups on the right hand side and it's just a more modern skin to the old...

Not the greatest answer but, its because my users know what "Start" means and when they are told to "Start and Log Off" they know exactly what I mean and where to move the mouse and which button to press.

Most of my users don't understand what "Right Click" mean. Yeah, its that bad! UGH

Its funny how users can manipulate their home pc's, create and send emails, scan, move, manipulate, attach files to emails and move all around. Then when they get to work, it all goes out the window and "I don't know how to do that!" Double UGH!

If their job is using a computer, they need to learn to use the computer. End of discussion.

You don't hire engine mechanics and just deal with them never learning how to open the hood for the lifetime of their employment. You expect them to learn how to open it, or turn on a car, even if the car changes.

Your users must learn computer basics if their job depends on them.

I finally had a clear night since getting my new camera. Although I wasn't prepared for the surprise clear night, I still got out for a few minutes to get a decent shot of M 42 (Orion Nebula) before my portable power unit died.

I'm excited to report that with only less than 20 minutes of data via EAA live stacking, I was able this get this awesome shot in my insanely light polluted area thanks to the L-Pro filter.

This gives me a lot of hope that once I am able to get out there and get a couple hours of data, I'll be able to get something awesome.

Below, M 42, an ad-hoc 18 minutes of data with a blown out core and a satellite streaking across (thanks Elon).

Hoping for some more clear skies in the near future and a trip to some darker skies!

I don’t do the furry scene. Sorry.

If you did, what animal would you be?

Everyone knows it would be a fox.

@shuey said in Advice on building "storage servers" with two DL380 G7 servers:

I'm uncertain about which RAID controller to go with. These are the three to choose from:

1. PERC H310 Mini Mono Controller
2. PERC H710 Controller with 512MB NV Cache
3. PERC H710P Controller with 1GB NV Cache

I'm not sure there would actually be any significant benefit in getting the 1GB NV card vs the Mini Mono...

Page 9.

Looks like the H310 doesn't have an NV cache, battery, and supports less RAID levels. The cache makes things way faster and adds life to your drives.

@Pete-S said in Copper Cabling - CompTIA Network+ N10-007 Prof. Messer:

Shielded cable is better but about 25% more expensive.

From what I've seen only residential and small office installations run unshielded. Enterprise runs shielded and fiber.

It's not the size of the company but in larger environments cables are more likely to be run into areas with lots of electromagnetic interference (EMI) for instance from speed controlled motors, fans in ventilation systems, elevators etc. In industrial environments, factories, manufacturing, production there are also lots of EMI. It's also more likely that the enterprise have lots of cables run together for instance in cable trays and cable ladders in which case shielded cables make more sense.

For newer cable types, like cat 7, unshielded don't exist anymore as they are all shielded.

And if you are in Texas, with all that air duct cleaning and plumbing going on, you're bound to run in to frequent abnormal interference.
