Nice find, Nick!

Though Windows 10 is the example used in the article, the same would apply to a 8.1 OS in UEFI mode, that is, for the few users of the OS. Actually 8.1 has some pluses over 7, in particular, power management. Have bookmarked the article for future reference, may be needed sooner rather than months down the road.

What I learned today, is not to be too friendly with another's cat. While she crouched & hissed at me upon arrival, eventually approached me, I reached to pet her, end result was getting bit rather hard on the hand.

Cats tends to have smaller, yet sharper teeth than dogs, and she likely smelled my cat's scent on me, prompting the bite. Now I can't wait until that relative brings the cat over here, we'll then find out who's the boss between the two, the relative is new to cats & doesn't realize that like dogs, they protect their territory just as viciously. Hopefully that meeting will be sooner than setting up a UEFI dual boot between 8.1 & MInt 18.

Yes, With this setup both OS's run with secure boot on all you need to do is change boot order in efi manager, while still in live session.

Edit bellow.

Sorry that involves typing terminal

Today I learnt that linux is a fantastic OS XD

No problem, as long as there's a demo to follow, it won't be a big deal.

This is how I've managed to run Linux Mint MATE for 7 years, have found many articles of good use (though will further research any I've never heard of), and have put to use on my Mint install. Have an extensive list of bookmarks of articles for when a reinstall is needed. 

I've learned (over a 7 year span) that one doesn't need to be a 'guru', 'expert' or whatever other term used to run Linux long term, and suspect many others does the same, by the reading of articles, or occasionally asking for a solution on a tech forum, such as our Community. Someone will have the answer, and will be what I've learned on that day.

Today....I found this tutorial. I already know how to set this up, but am sure that others will find it incredibly useful....(especially if they are having 'trouble' cutting the windows umbilical cord.....)

(How to install win 10 in a virtual box on linux)

I learned how to drive one's self insane with Ubuntu 16.04 (regular) iso's...and thought I'd share just for laughs.

A little background:  Thanks to everybody's help with the monitor issue I was having, I got Mate 16.04 installed alongside Mint 17.  Then for some reason, I thought it would be fun to download regular Ubuntu 16.04 just to compare with.  Download went ok, and the sha256 checked out in GTKHash fine.  So I burned 1 DVD, and set about trying to verify that using the methods we discussed here.  This is where the fun begins.  Long story short, I burned 3 DVDs, and couldn't get the sha256 to verify until I tried a command Hollowface recommended in the "verifying checksums" thread for when the burning application "adds some padding" to the disc.  Then it checked out.  Total amount of precious life lost: 5 hours, not including typing this up.

The kicker is I still can't figure out why these disc's came out differently.

You know there is no need to hash the Disk right?  I did it because I did not have the original iso to hash.  Once the iso is hashed you are good to go! just check Verify before the Image Burn.  And one can even Verify the Disk upon Boot, there is an option there to do so.  Good one to know though.

 

You know there is no need to hash the Disk right?

And now I learned that...    a very enlightning day, LOL.

Seriously though, that was part of the original instructions I was working from.  Oh well, at least it wasn't a boring day.

Something that Rocky Bennett shared with us yesterday in another Topic, was wondering 'where had my digital sound gone?' (4 way) on my MSI FX603 notebook that had just been upgraded barely over 30 hours ago to an i7-620M from an i5-480M, when running Linux Mint MATE. When I first purchased it new in 2011 & with Windows 7 only, sounded great for what it is. Now I know where the sound went.

 

 

With Microsoft bit perfect sound is very easy using WASAPI https://msdn.microsoft.com/en-us/library/windows/desktop/dd371455%28v=vs.85%29.aspx. With WASAPI as a component to my jRiver or foobar2000, an audiophile can achieve bit perfect music playback. Even with my modest little system, I can easily tell the difference between ALSA and WASAPI.

There showed to be a clear difference in clarity, even with my low cost DYNAUDIO speakers featuring THX sound control, between the music on the Windows 7 OS rarely booted into, versus Linux Mint 17.3 with ALSA (analog 4.0 surround), which is used daily. Information in Post #22 below. Comparing music played with VLC was like the difference between day & night. 

http://www.bleepingcomputer.com/forums/t/613169/should-i-use-windows-or-linux/page-2

Now I know which OS to use for music, and which to use for security. The cool thing being a notebook, can listen to my music while on the PC at the same time, w/out compromising security for music quality.

Next on the upgrade list.....sound card for PC with TOSLINK output, which at first glance appears to be connected by wire, when in fact it's a fiber optic cable with internal red light, rather than copper wire, to reproduce quality digital sound. Am surprised that upper mid to higher end PC's (anything $1,000 & up) doesn't include this option. Dell has been pushing 'Grammy Award' winning 7.1 MAXXAudio for at least three years, so TOSLINK would had been a perfect compliment. When did a sound standard begin being awarded the Grammy? Normally this is awarded to actors, actresses, musicians & writers for their talents. 

Still, though Dell pushes it to this day, doesn't include the complete suite that MAXX offers. Have never seen all of these controls in the onboard sound (when used). Yet on a less than $75 motherboard purchased in bulk by Dell, I suppose it's to be expected.

I learned that many of the formerly popular download managers like FatRat, Multiget, and wxDownload Fast are dying out. They've not been updated in many years.

I learned that many of the formerly popular download managers like FatRat, Multiget, and wxDownload Fast are dying out. They've not been updated in many years.

Down Them All (Firefox download manager) is next on the hit list, along with the popular NoScript Security Suite, as Mozilla is making a shift towards becoming yet another Google Chrome with their skin on the browser. They've enjoyed a close relationship for years anyway, so it comes as no surprise. Out of desperation to gain market share, Mozilla teamed with Yahoo, which worsened it's situation. No one who cares to find fast (& safe) results uses Yahoo, nor AOL anymore. This isn't the mid 90's through early 2000's (around 2004 or so), teaming with either are a dozen years behind the times. 

I learned today that the only way to update a Windows 7 that won't do so upon request, to set updates to download and let me choose when to install & let it sit for about six hours idling while taking a nap. Then go to it, and at the shutdown tab, there's a tab that shows there's updates downloaded to be installed. So that any undesired updates won't be installed, reboot rather than shutdown, and the updates are staring me in the face in about a minute. Then I hide the ones I don't want (telemetry, CEIP & any to do with upgrade compatibility) & install the security updates only. 

Fortunately with Linux Mint, all of this effort to update an OS isn't present, can clean install an OS & have it setup the way I like before Windows 7 downloads a dozen updates.

Today I learned about:

sudo apt-get check

me too. WHY???

This is something that frequently happens to me.  I frequently copy and paste code found in the forums or even in tutorials relating to various things that I need or want to explore. I know the text has been entered correctly but instead of getting the output expected I get command not found.  This xxxx is not available, or various other reasons for the terminal being unable to execute the command or even worse nothing just a return to the $ sign..  Very frustrating.  In this case no data. From this point of view Linux is very challenging to complete newbies but I like the challenge and could no more go back to using windows as a daily OS than eat my shoes.

My grandchildren have used Ubuntu ever since they have been able to use a keyboard and being kids (7 & 9 years old now) they just sat down, started using it, figured it out and got on with it.  Now when using their Mum's windows 10 laptop they frequently voice their dislike. 

A lot fewer people would use Linux if it were not for the experienced people on forums like this who give so much in time and effort to help binheads like me.
