Be advised that if you want to use VM/VBox under linux to get some Windows stuff or games running, many have their VBox currently messed up due to the new Linux Kernels which contain the mitigations for Spectre/Meltdown. At least under Mint I read in the major German Mint forum that several such Kernels yesterday and the day before caused problems with VBox. Probably gets fixed with time as well.

If you use Haswell and Broadwell: don't touch these upcoming or out-in-the-wild firmware updates.

After patches for broken patches for broken patches by which Microsoft wanted to tackle it sbroken AMD stuff", now comes Intel and tells people to immediately stop upodating processor firmware.
https://www.computerworld.com/articl...are-fixes.html This news made my evening. Never again shall I be called "computer paranoid"

Which is why things like "Force Feedback" Joysticks and Racing Wheels needed external power supplies, but a Mouse or Keyboard would not. Any time you plug in anything into a powered outlet, it has power. And since most (all?) usb "jump drives" are not switched. It is on. Whether or not it is "mounted" (i.e. hardware is made access-able via the file system) is independent of the device being "powered". Note: I may have misread some of the post on this line of discussion, My apologies if this is the case! Quote:
(In addition to the reasons Propbeanie listed) The drive/storage starts with little or no "charge", current is used to flip the "gate" from "off" to "on", i.e. "0" to "1". Current is now stored in the "gate"/"switch". "Data" is now stored on the SSD. (all the "1"s representing a "bit" and that part of the data, 'write' all "0"s to a drive and it is "erased") When the drive is erased/data is deleted, current is used to flip the "gate" from "1" to "0". But there is still residual "charge" in "gate". When new data is written to the drive, it flips the "gate" again.... to "on"/"1". Deleting data repeats the switch back to "off"/"0". But there is slighting more "charge" than last time. This process keeps repeating until the drive controller can no longer supply enough voltage to flip the "gate" to the other state (off/on 0/1). Similar to how a car battery charger must output greater VOLTAGE (very basically: electrical "pressure") to charge a car battery (car batteries are usually 12.99 volts when "dead" and 14.5 volts when "charged"). Which is why most car alternators are around 15 volts. Also a problem with SSDs: If the current "decays" then the drive "forgets" the data. ----------------------- I've been following the Linux kernel patches since this started. Most of the performance reduction seems to be related to primarily one task... I/O, some links to benchmarks: Initial (I think) batch of benchmarks: https://www.phoronix.com/scan.php?pa...5-x86pti&num=1 More test, also he explains a bit more: https://www.phoronix.com/scan.php?pa...e-x86pti&num=1 This gentleman is always running test and benchmarking... I find it useful to see what's coming up soon. He test mostly on Ubuntu (unless it a comparison between distros), usually with the latest "git" code (i.e the latest code from the development "branch"). Barracuda |

Everybody, stay away from any BIOS or UEFI firmware updates.

Since years...? I admit this was new news to me today. Although i repeatedly said that MS's design of W10 may be due to orders by the NSA.

Intel says new Skylake fixes are out to brick more BIOS and UEFI , eh - I mean they said the first part and skipped the latter.
Before you now jump up and run to get these firmware updates done, read this and see if you cannot find reason for some reasonable caution in it: https://www.askwoody.com/2018/intel-...atch-is-ready/ Quote:
