Linux Mint Forums

After I logout and login with another account then login again with my regular account that sign it disappear.
Strange... maybe it has something to do with vlc as I did not install any new sw on my computer just messed a little with vlc setting and some updates from manager.

Hello,

I noticed few days ago that a new sign appeared on top of active window and I have no idea why.
Any idea how I can get rid of this ?

Have a look at Ventoy:

All you have to do after you install Ventoy on your stick or portable ssd/hdd is to copy iso files and you can boot it instant.
It work ok with Linux Mint iso.

For protecting against data theft and unauthorized access you can use: - FULL HDD/SSD real-time encryption with password at computer power UP ( you need BIOS and HDD/SSD firmware support and it will protect all data on HDD ). - BIOS power on password. ( you need BIOS support ). - Home folders encryp...

why I can't disable/delete only firefox profile... firefox not starting because firejail firefox profile missing even after firecfg --clean and --fix...
"apt-get purge firejail" fix this crap forever.

Some people still understand ASM, this is not the point. ~28 years ago I used to program in ASM self-replicate code that changed his form; compiled working code had final size under 2Kb. Have a look at microcode length, it size is from 2Kb to 100Kb... this is huge for pure ASM code just to correct s...

Spot on.
Intel microcode for sure it is Intel proprietary and encrypted.
It can contain anything Intel want including a bonus backdoor.

I don't think i3-2350M have microcode update to mitigate Spectre / Meltdown yet.
check and see if date is at least 2017-07-xx or newer.

Because Intel can lose so much money that we can't even dream if they lose control of the damage and what a better way than to have everything fuzzy and minimize the impact of this problem with careful crafted PR statements.
Time is passing and other security problems will hold the news.

I tested myself few old CPUs in hw I have here: N3530, I5-520M, I5-3470, E8400, E8500, Q6600 with latest Intel microcode-20180108 and they have no new microcode update since microcode-20171117 and previous. Tested new I5-7400 CPU and it have a microcode update. Test yourself and let us know for what...
