[gentoo-user] SDD, what features to look for and what to avoid.
Howdy, Tuxic's recent thread brought me back to looking at SDDs again. I recently learned about HDDs having SMR instead of PMR and how that can be a negative in some situations. I've since found out that one of my /home drives is a SMR. I didn't know to look at that when I bought it. So, before I find a SDD to buy, what are some things I should look for it to have and what are things I should avoid? I'm sure SMR and PMR doesn't apply here but I bet you gurus have ran up on things the hard way to either avoid or make sure SDDs have. As is, the OS itself is on sda. That includes everything except /home which is on two drives using LVM. It's about 9TBs or so I think. One 6TB drive, SMR I'm afraid to admit, and a 3TB drive that I'm pretty sure is PMR. I may put /var on a HDD since it changes a good bit. Everything else, except /home, would be on the SDD. Anyone care to share? While at it, if I look for a NAS type HDD, would all those be PMR instead of SMR? From my understanding that should be correct. Mostly I buy WD, Seagate and Samsung. I've had a WD fail, I've had a Seagate fail. I'm not looking for a HDD flame up. O_o I'm starting to look at HGST. I think I got the spelling correct. Never had one tho. Thoughts? Dale :-) :-)

Here's my thinking. Set up a chroot or a virtual machine thingy on a regular hard drive. Copy your OS to that, do the updates and then copy packages over to your running system. Then you just emerge -k world and all it does is install binaries on the running system using the SSD. The other benefit of this is a much faster update on the running system. Also, if you get part way through a update, qt or KDE for example, you don't end up with a running system with mismatched versions and possibly a system that doesn't function correctly or won't let you do anything at all, or login even. You can fix the build problems in the chroot/VM and use the running system in the meantime. I started doing this recently because I ran into issues where KDE/qt/something else was not completely updated due to failed compiles that stopped the updates. Some programs I needed wouldn't start or no longer would work correctly if already started. It saves me some grief but would keep the larger writes off your SSD and on a HDD. Oh, if the HDD were to fail, no loss there either. Replace it and start over. I have some scripts, that's a VERY generous use of the word, that I use to mount the chroot, copy the updates over and copy the packages over when compiling is done. I'm still perfecting this but so far, it is working nicely and should work for you as well. Someone else may have a even better idea tho. Dale :-) :-)
[gentoo-user] SDD strategies...
Hi, currentlu I am setting up a new PC for my 12-years old one, which has reached the limits of its "computational power" :) SSDs are a common replacement for HDs nowaday -- but I still trust my HDs more than this "flashy" things...call me retro or oldschool, but it my current "Bauchgefühl" (gut feeling). To reduce write cycles to the SSD, which are quite a lot when using UNIX/Limux (logging etc) and especially GENTOO (compiling sources instead of using binary packages -- which is GOOD!), I am planning the following setup: The sustem will boot from SSD. The HD will contain the whole system including the complete root filesustem. Updateing, installing via Gentoo tools will run using the HD. If that process has ended, I will rsync the HD based root fileystem to the SSD. Folders, which will be written to by the sustem while running will be symlinked to the HD. This should work...? Or is there another idea to setup a system which will benefit from the advantages of a SSD by avoiding its disadvantages? Background: I am normally using a PC a long time and try to avoid buying things for reasons like being more modern or being newer. Any idea to setup such a sustem is heardly welcone -- thank you very much in advance! Cheers! Meino

Based on what the link claims, it allows you to watch videos, read articles and such later even if offline. If I like a page, I save it or print it as a pdf or copy and paste it into LOo. It might be a long way around but it makes it available even if the website removes content or shuts down completely, forever. Still, I likely don't understand all it does but I disabled it since I don't think it serves a purpose here for me anyway. Maybe others will. I wonder what else Firefox does I don't know about Dale :-) :-)

Pocket is easily replaced by just synchronizing bookmarks, for most people's purposes, and FF already supports that. If you need more than that, I can recommend Wallabag for link-saving. I use it as my "read later" list.

After some looking, I found a link in about:config. It lead me to this.
https://getpocket.com/about
That tells a little about what pocket is. Pardon me while I go disable
stuff. Anything that can do, I can do locally by saving a web page or
downloading the content.

I don't want to set them to false because I still don't know what they
do, google didn't help any either. I don't want to break websites or
something and then be trying to figure out why a site works for everyone
but me, and maybe you if you happen to visit the same site. ;-)
Can someone share a link that tells what a pocket is exactly? If I
don't need it, I'd like to disable it. It may help with the extension
thingy that takes up tons of memory and sends one core of my CPU to
100%. So far, restarting Firefox is the only solution. It sometimes
hit several GBs in no time flat. It runs fine for days and then BAM.
Overload. :/
Thanks.

I didn't even know what pocket is, let alone that it is enabled as a default.
I'm on FF 68.6.0esr, but I do not have a pocket button showing in the address
bar. I may have disable it sometime in the past, thinking that got rid of it
- little I knew.
Going to about:config and searching for pocket reveals a number of related
settings, with 'extensions.pocket.enabled' being one you should pay attention
to.

It is worth mentioning, Palemoon does not have pocket in it. ;-)

I admit I don't know what these are for but I went to look at mine. I
also found this which is a little different than the one you posted but
still pocket related.
services.sync.prefs.sync.browser.newtabpage.activity-stream.section.highlights.includePocket
I run unstable here but mine is set to true for that one as well.

[gentoo-user] Pocket sneaks back
After the latest stable firefox upgrade to version 68.6 I again started
seeing DNS queries for Pocket related domains. I found this in
prefs.js:
user_pref("browser.newtabpage.activity-stream.section.highlights.includePocket",
true);
I am not sure if this setting was new with this version or if firefox
just started acting on it now, but in any case I am adding it to my
user.js with a value of false, right now.

hi - is that true? it seems to be using it automatically when tor.service is running. what's the point? e.g. is it made to ensure that we reduce the probability of having a single man in the middle that may consistently fool us? by replacing it by varying men in the middle that is harder for them to coordinate a consistent lie? and what do you recommend me to do in order look like the cool kids? rgrds, cm.
[gentoo-user] os-prober fails sucessfully
Hi all. I'm having a problem with os-prober not finding other linux partitions. I'm on x86_64 and an old spinning drive with an msdos partition table and 4 primary partitions, 3 linux and 1 swap. os-prober runs successfully as per bash's return code, but no partitions are found. grub (grub2) is built with the 'mount' use flag, and when 'grub-mkconfig -o /boot/grub/grub.cfg' is run, the result is the same, i.e., the gentoo partition is found but no others. Any suggestions on where to check from here?
