I had no experience in nixOS, just went to the package website, it tells you exactly what to add to each section of the config.

BCsven ,

I haven't tried that one but besides the package page there is the options pages that gives you the ability to define config info.

Working can be purpose, as can hobbies. we all need purpose

BCsven ,

:)

BCsven ,

In theory if you have a circle of friends already, then social should be better with WFH because when it is quitting time you are immediately done and have more evening for social gatherings. if you recently moved cities before WFH, not having colleages might cut down chances of finding new friend groups

Give this systemd lecture a watch it explains the
why https://www.youtube.com/watch?v=o_AIw9bGogo

BCsven ,

Distro dependent, and hardware dependent. Some have a great experience OOTB

BCsven ,

I had great luck with OpenSUSE Leap on two machines. Another machine was really old and OpenSUSE was a bit slow on it so tried debian, it struggled with all debian based distros I tried. But NixOS has been amazing on it with 0 issues. It really is a dice roll.

BCsven ,

Yep, to me there are two groups that linux works well for (at home)

  1. tinkerer type who likes new tech.
  2. completely computer/ tech illiterate type ( like my wife or mom)

In the 2 category if they just need a computer for netflix, browsing, email and zoom calls you set them up with a stable diatro and it works the same every day with no windows surprises.

BCsven ,

I heard the hype, did an install of arch ( before the installer script ) followed the wiki and was done and running gnome desktop in a very short amount of time.
However, the tweaking afterward is where I prefer a currated distro.
i.e. My OpenSUSE does snapshot cleanups on its own based on time or number, btrfs scrub and other jobs happen without me having to touch a command line. Sometimes I just want to get work done and not worry about the OS.

BCsven ,

Others replied about WINE translation layer, but once binary is loaded in memory the kernel juat runs the code it does not care that it is linux or windows code, because to the systembit is chip instructions. It is why LinuxOS was fully able to run DOS way back when

BCsven ,

Don't do it, is my suggestion. Surveillance disks are optimized for continuous writing performance and not read performance. They mght be SMR version also which can play havoc in a NAS with lots of writes, as it can't just rewrite one portion without relaying out the shingled overlayed tracks adjacent.

BCsven ,

If you can't find the drives you want maybe reviewing/testing acoustic Management might be something to help reduce noise.

According to 2.5admins shucked drives are not as good as the red/pro. They are the drives that didn't meet the requirement for QA; so they go to external plug in drives, that the seller hopes the user doesn't use them to the same rigourous performance of a true server daily requirement

BCsven ,

I can only relay what two server drive experts have explained. 2 of the guys in this podcast make their career on drive setup and
performance.

https://2.5admins.com/

Also, remember when Seagate and WD tried to downplay SMR vs CMR disks in their NAS lineup but end users had their servers kicking out the SMRs from the pool? Sometimes in shucking you might get an SMR drive which sucks.

BCsven ,

The SMR does make sense for surveillance, because it is a constant stream layed down, it is not random write access changing a block in files of various places.
This show has talked about their usage.
The tolerance on dropping bits to keep going with the stream would worry me in data sensitive applications

https://2.5admins.com/

There are spec sheets, but I have tested myself, brand new Purple Drive out of package and run disk bench marking read/write testing. Writing was steady, read rate was under performing compared to Blacks or Reds.

BCsven ,

LOL. I mean depends on the baseline number, so yeah, you would be correct. But the concern would be as you mentioned the Purple drives don't care (as much) about data loss. Fine for video if you lose a pixel, but bad for mission critical data.

BCsven ,

oof, I have to upgrade one of my drives then, since those options are showing in the drive config. But yeah, my newer drive has this option greyed out. Only performance vs power saving is and adjustable slider on the new ones. Interesting thing is google says that article was from September 2023, so it is quite out of date then.

BCsven ,

Yeah, I don't diagree on Value, I just would not trust them on mission critical. If you listen to back catalog of 2.5admins they explain in detail about what you could encounter. On the flip side drives are supposed to last 10 years, I have a 13 year old one still chugging away.

BCsven ,

I'm not sure if this is accurate OpenOffice appears to be abandonware with development stopped in 2011 while LibreOffice is the fork and still being developed.

edit...ah Oracle OpenOffice vs Apache OpenOffice

  • install windows
  • adjust main partition so you have space for Linux
  • install linux, during install create anither efi partition, and root partition.
  • linux probes foreign OS (some distros might not) and creates a chainloader entry from your new EFI to Windows EFI
  • set BIOS to boot from linux EFI

Windows never knows the other partition exists and leaves it intact.

BCsven , (edited )

You do need a separate EFI, even though linux finds EFI, otherwise windows update trashes it randomly and why the meme we see here exists, with separate EFI windows doesn't know about it. You can shutdown windows mid update and boot linux, then reboot back to windows and update will continue. Siloed System

BCsven ,

Yes. When you install Linux it will auto detect the Windows EFI partition and put boot stuff there by default, but then windows comes along and will randomly trash that setup. So during install don't go with the suggested option, instead use the partitioning tool to creat another small EFI boot partition elswhere on disk, leaving Windows EFI and OS paetitions as is. Also create your root and home partition(s).
Install to those partitions, then Linux should prompt for Probe Foreign OS and add a chainloader entry to your grub menu. This entry, when selected, points grub to windows EFI partition ID and hands off the boot process to Windows. Windows is unaware it has been chainloaded.
As long as you set BIOS to load directly from the LINUX EFI entry then you will boot to Grub with Linux/Windows Dual option...But technically it is not a true Dual Boot, it is a sequential boot I guess.
I have had this for 7 years on same install and boot between W10 and Linux daily. Windows has never touched my Linux EFI.

BCsven , (edited )

It will, thats why that meme exists.

Not during typically reboots, but when some windows update or autofile repair happens it thinks it is the only OS on that partition and does what it likes.

BCsven ,

Then you have been lucky, because most peoples experience with grub EFI on Windows partition is windows will eventually scrub it.

BCsven ,

Makes no difference of what bootloader, just that windows thimks it owns that partition

BCsven , (edited )

For something like OpenSUSE you go into YAST2-GUI and click the probe foreign OS and then it asks you if you want Windows or Linux as the default boot. But to do it manually you add a menu entry to /boot/grub2/custom.cfg. or in /etc/grub.d/40_custom. After editing this you will have to run grub2-mkconfig -o /boot/grub2/grub.cfg which will compile all the grub info into /etc/grub2/grub.cfg
I believe the custom.cfg entries end up after the 40_custom entries that the OS may have included.
There is a persistent method entry if you did want to edit the /etc/grub2/grub.cfg directly, but probably not advised.

Here is my entry for Windows boot partition and location of MS boot. Also below that is a UEFI entry for geting back to the BIOS, not relevent to this topic, but just so you see how the menu entries are defined. In my system these are at the end of all the other Linux entries.

### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows Boot Manager (on /dev/nvme0n1p2)' --class windows --class os $menuentry_id_option 'osprober-efi-4E48-193F' {
	insmod part_gpt
	insmod fat
	search --no-floppy --fs-uuid --set=root 4E48-193F
	chainloader /efi/Microsoft/Boot/bootmgfw.efi
}
### END /etc/grub.d/30_os-prober ###

### BEGIN /etc/grub.d/30_uefi-firmware ###
menuentry 'UEFI Firmware Settings' $menuentry_id_option 'uefi-firmware' {
	fwsetup
}
BCsven ,

I responded how to via another comment, but wanted to mention that you may have a chainload to Windows already with your dual boot, but the main point was using two EFI partitions and chainloading to the other one, so Windows isn't ever in charge of files in your linux boot partition

BCsven ,

By Boss it should say Corporation, or Large Corporate Boss. Because many bosses at companies are earning same as you and got more responsibility dumped on them.

BCsven ,

I'm lucky I guess our company owner leads by example and believes in open financial statements. We all see what the company makes, what the expenses and labour are, and how much profit has been generated

BCsven ,

As SU type mail, you can read what meesages got sent to root@machinename

BCsven ,

Depends on them not choosing wrong raid type :)

BCsven ,

2 Single drives means 2 full copies, one you can keep at a friends place. 2 mirrored drives means if you accidentally overwrite a backup, you have lost both drives to the error, unless you have snapshotting or imcremental backups.

Lots of good backup advice on this podcast https://2.5admins.com/

BCsven ,

Where? not in what i replied to

BCsven ,

I mean yes if time is an issue, but compiled code on your own hardware is specifically tuned to your machine, some people want that tiny tweak of performance and stability.

BCsven ,

But compiled on some other machine. Compiling on your own hardware optimizes it for that specific hardware and what that chip supports etc.

BCsven , (edited )

Ah, thought you meant in the AUR. I'm used to OBS where you have binaries and source available (OBS meaning OpenBuildService, not the screen recorder)

BCsven ,

Closer to thr 5% . Between the intermediate code and final code writing there is an optimization stage. The compiler can reduce redundant code and adjust based on machine. i.e. my understanding is an old 4700 can have different instruction sets available than the latest intel.gen chip features. Rather than compile for generic x86 the optimization phase can tailor to the machine's hardware. The benefits are like car tuning, at some point you only get marginal gains. But if squeezing out every drop of performance and reducing bytes is your thing then the wasted compiling time may not been seen as waste.

BCsven ,

I have PiHole and OpenMediaVault (with homeassistant docker, and dlna music server) running on a Pi2 2Gig. It has been totally fine

BCsven ,

They will, they will add a nano particle that is sensed by printer

BCsven ,

Yes

BCsven ,

Technically SSDs will forget numbers too if left disconnected from power and in a hot room

BCsven ,

That is why I Ilisted the unpowered/ unplugged. there are white papers on ssd data loss when it is disconnected from mobo and stored. The lack of trickle power allows decay in the mem cells simce they are just packed charges, and heat accelerates that loss. They said in as little as a week in a hot room it will have started bit rot. And in some cases a few months in a hot space (say 40 degrees in summer heat we have) and data is gone.

BCsven , (edited )

Not the whitepaper research paper I was trying to reference but if you read just below the temp chart image is explains similar info about how quick SSD (unpowered) data loss is based on ambient heat. HDD while also succeptible to data loss is a better archive medium than SSD https://www.anandtech.com/show/9248/the-truth-about-ssd-data-retention

BCsven ,

Like I said that is just one link, there was a recent whitepaper about it, just lost my link.

Finally got a UPS

Keeping tradition with doing things backwards, I've finally got a UPS for the rack (mounted in the bottom of the stack). Got a PowerWalker VI 2200R. Its a 2U unit which is all the space I've got left in the rack. Decent price and decent I/O with USB, serial and a slot-in for network expansion + 4 IEC outputs. Its powering...

BCsven ,

+1 for UPS. So many PC gamers on reddit crying about their build getting fried by a power fluctuation. I never understood somebody that would drop 2-3k on a graphics card but not $300 on clean power delivery

BCsven ,

Sorry, initailly replied to wrong thread. Not meaning total loss of power, but power fluctuations, brownout, over volt, amps and volts out of phase. You won't normally don't notice because it is short, or not noticable in lights or monitor etc. But with active UPS monitoring you can watch spikes in your power grid. A UPS will see this and rectify power to within normal range. Or an occasional drop in voktage will kick in the UPS to bridge the power drop gap. Then there are major surges that a UPS will buffer by regulation or breaking power to your device.

BCsven ,

Depends on how much you spent on your PC, and how reliable your grid power is. Ours is decent, but we get windstorms that create variation in the transmission. 13 years ago I didn't bother with UPS but then we had a power failure, back on, failure , back on, all within a second or so. Killed my Dell Powersupply and graphics card blew one hdmi port. Since then I have had one. had to change the battery last year for $80. It has saved me from brownout when a crow vapourized itself on the transformer outside our place. And every few months the logs show voktage correction for overvolting AC. it is cheap insurance that your syatem is getting clean power.
Last month my laptop charger power pack shorted internally, so UPS immediately shutdown power. Even if it wouldn't have overloaded the laptop, it possibly prevented a fire since the short was not enough draw to blow the panel breaker.
