[05:00] <gry> is it freaking serious? ubuntu hibernation option is off by default?
[05:01] <lotuspsychje> gry: hibernation is the users choice
[05:01] <lotuspsychje> its not because you like it, everyone needs to sue it?
[05:01] <lotuspsychje> *use
[05:05] <lotuspsychje> gry: also alot of brands suffer hibernation acpi bugs on linux, that needs to be solved first before working properly
[05:55] <akemhp> Yeah, but still it would be better if there was an easy way to automaticly set the needed swap space, boot parameters disk ID/offset, and grub update, because you have to deal with command line and text editors. It can be annoying for lots of users i guess.
[06:22] <lordievader> Good morning
[06:46] <ducasse> good morning
[06:46] <akemhp_> Good morning ;)

[09:46] <marcoagpinto> Hello!
[10:06] <gry> hi
[10:58] <gry> lotuspsychje: is it planned to fix these bugs with hibernation in next release? a user was asking about why hibernate is missing in the channel yesterday?
[10:59] <lotuspsychje> gry: im affraid we cant generalize hibernate bugs, as they are brand specific
[11:00] <gry> ok ok
[11:00] <lotuspsychje> some brands will always get buggy on several ubuntu versions
[11:00] <lotuspsychje> we often reccomend updating bios to latest and workarounds with acpi boot lines
[11:00] <lotuspsychje> !acpi
[11:00] <ubot5> to debug ACPI issues on ubuntu make sure your bios is up to date and follow the procedure here: https://wiki.ubuntu.com/DebuggingACPI
[11:01] <gry> yes
[11:20] <BluesKaj> Hey folks
[11:25] <marcoagpinto> BluesKaj!!!! Hello!!!!
[11:25] <marcoagpinto> >:)
[11:26] <BluesKaj> hey marcoagpinto
[15:07] <EoflaOE> marcoagpinto!!!!!
[15:16] <marcoagpinto> EoflaOE!!!!
[15:16] <marcoagpinto> >:)
[15:16] <EoflaOE> How are you marcoagpinto?
[15:16] <marcoagpinto> I know i shouldn't be doing it, but I am drinking more cola :(((((((((((((
[15:16] <marcoagpinto> what's up?
[15:18] <EoflaOE> I am doing fine.
[15:19] <marcoagpinto> cool
[15:19] <marcoagpinto> :)
[15:20] <marcoagpinto> does Ubuntu allow to save directly in a disc?
[15:20] <marcoagpinto> the other day I went to help a person with his computer and Windows 10 records directly to CD with drag'n'dop
[15:20] <marcoagpinto> drop*
[15:20] <lordcirth> marcoagpinto, save how? what do you want to do?
[15:21] <marcoagpinto> well, normal files
[15:21] <marcoagpinto> :)
[15:21] <marcoagpinto> I have Nero, so I don't need it, but most people don't have commercial software
[15:22] <lordcirth> marcoagpinto, so, just writing files onto a CD?
[15:22] <marcoagpinto> yes, with drag'n'drop
[15:22] <marcoagpinto> :)
[15:22] <lordcirth> Probably. I don't think I've put files on a CD in at least 5 years.
[15:23] <marcoagpinto> me neither :)
[15:23] <marcoagpinto> I just create .iso's now-a-days
[15:23] <mgedmin> so either that's a CD-R and windows lets you drag'n'drop a bunch of files then hit a burn button somewhere to write them out
[15:23] <marcoagpinto> no button
[15:23] <mgedmin> or that CD-R (CD-RW?) is using the UDF filesystem, and I'm not sure Linux supports that
[15:23] <marcoagpinto> it copies to CD just as if it was a normal folder
[15:23] <marcoagpinto> :)
[15:24] <marcoagpinto> and after we select eject it says "closing session to make it work in other PCs blah blah"
[15:24] <mgedmin> wikipedia says Linux supports UDF in read-only mode only
[15:24] <marcoagpinto> ohhhhhhhh
[15:25] <mgedmin> wait, for UDF revision 2.50/2.60
[15:25] <mgedmin> it's read+write for UDF revision 1.02 throug 2.0x
[15:25] <mgedmin> I find this table hard to read: https://en.wikipedia.org/wiki/Universal_Disk_Format#Compatibility
[15:25] <marcoagpinto> ahhhh
[15:25] <marcoagpinto> :)
[15:26] <mgedmin> I don't know if the desktop & nautilus are smart enough to recognize a writeable UDF-formatted disk and allow you to copy files to it, though
[15:26] <mgedmin> or how you'd go about formatting a blank CD-RW/CD-R disk as UDF
[15:26] <mgedmin> but now you know what technical terms to google!
[15:27] <lordcirth> apt-file search mkfs.udf: udftools
[15:27] <mgedmin> https://gitlab.gnome.org/GNOME/gparted/commit/5f327feb25bcb8b55ffa2eab1bb86d5f75d75fba was 2 years ago
[15:27] <marcoagpinto> ohhhhhhhhh
[15:27] <marcoagpinto> NetBSD 5.0 has "yes" in all columns
[15:27] <marcoagpinto> :)
[15:28] <marcoagpinto> what is a NetBSD?
[15:28] <mgedmin> but "formatting optical disks is not supported yet"
[15:28] <mgedmin> NetBSD is an OS, very much like Linux, except less popular
[15:28] <mgedmin> more oriented to servers than desktops
[15:28] <marcoagpinto> ahhhhhhhh
[15:28] <marcoagpinto> :)
[15:32] <marcoagpinto> when I bought my SSD drive for the 14'' laptop two years ago or so I thought it would become very fast for Windows and Ubuntu... but the computer manufacturers are still shipping SATA2 :((((((
[15:33] <marcoagpinto> so, it can only read up to 300 MB/sec and not 600
[15:34] <mgedmin> I thought the primary advantage of SSDs was low seek latency (0 vs 10ms), not throughput?  my first SSD only did 100 MB/s (compared to the 40 MB/s HDD I had before), but it made my old laptop feel brand new at the time
[15:35] <marcoagpinto> mgedmin: I know SSD is a lot faster than conventional HDD :) but I thought I had a SATA3 interface in the laptop
[15:35] <marcoagpinto> I was shocked when it said "sata2"
[15:37] <mgedmin> my current SSD does 1138.67 MB/sec according to hdparm -t -T /dev/nvme0n1, and I'm not sure if I believe it, or if hardware really has progressed that far
[15:37] <mgedmin> there's a "HDIO_DRIVE_CMD(identify) failed: Inappropriate ioctl for device" just before the result which doesn't make me trust hdparm
[15:37] <marcoagpinto> mgedmin: NVMe does 2,5 GB/sec I believe
[15:37] <marcoagpinto> :)
[15:38] <marcoagpinto> at least the SAMSUNG ones I read about
[15:41] <marcoagpinto> https://www.samsung.com/us/computing/memory-storage/solid-state-drives/ssd-970-pro-nvme-m2-512gb-mz-v7p512bw/
[15:41] <marcoagpinto> "3,500MB/s Seq. Read"
[15:41] <marcoagpinto> :)
[15:43] <marcoagpinto> it would boot my OS in one second!
[15:43] <lordcirth> Optane is the fastest of all, though the price matches.
[15:44] <lordcirth> We have some 1.5TB Optane NVMe for Ceph metadata & journals. It's good stuff.
[15:45] <mgedmin> modern software is amazing at taking all the speed advances hardware has made over the years and making it slow again
[15:45] <lordcirth> "software gets slower faster than hardware gets faster" :P
[15:46] <marcoagpinto> lordcirth: What a good sentence to say in my exam :)
[15:51] <marcoagpinto> ohhhhhhhhh... the prices dropped a lot
[15:51] <marcoagpinto> $150 for that SAMSUNG drive (512 GB)
=== gry_ is now known as gry
[17:14] <EoflaOE> marcoagpinto I will get a SanDisk USB 3.0 drive.
[17:15] <marcoagpinto> EoflaOE: Why not a T5 SAMSUNG one?
[17:16] <EoflaOE> marcoagpinto: Well, my local store doesn't have the T5 Samsung flash drive.
[17:16] <marcoagpinto> ohhhhhh
[17:16] <marcoagpinto> order from Amazon
[17:16] <marcoagpinto> :)
[17:18] <EoflaOE> marcoagpinto: I would, but because I live in Syria (which still has a sanction to now), and don't have a credit card, I have no option.
[17:18] <marcoagpinto> ohhhhhhh
[17:18] <marcoagpinto> I thought you lived in Europe
[17:19] <EoflaOE> OK marcoagpinto. I will look at its picture.
[17:20] <EoflaOE> Well, it's an SSD, but nice look.
[17:20] <marcoagpinto> yes, it is an SSD
[17:20] <marcoagpinto> :)
[17:20] <marcoagpinto> I will probably buy it next year
[17:21] <marcoagpinto> On Christmas I no longer need to buy a new mobile phone since a software update gave ~4 GB more free storage in it
[17:21] <marcoagpinto> I had less than 1 GB of storage free
[17:22] <marcoagpinto> my guess is that the Android update created temporary files and only now they were deleted
[17:22] <EoflaOE> Nice. To Android 10.0?
[17:22] <marcoagpinto> no
[17:23] <marcoagpinto> years ago, from 6 to 7
[17:23] <marcoagpinto> :)
[17:24] <EoflaOE> So good. I am planning to buy the next Android tablet, this time, from Samsung.
[17:25] <marcoagpinto> my parents have Samsung, I only use Sony
[17:27] <EoflaOE> OK.
[17:29] <EoflaOE> When I was Grade 4 in 2014, the school gave ever student a cheap Chinese tablet, XTouch F81: https://whatismyphone.com/vendors/xtouch/f81 Their website seems to be down.
[17:29] <EoflaOE> every*
[17:30] <marcoagpinto> :)
[17:30] <marcoagpinto> I am not good at Android :)
[17:30] <marcoagpinto> I can't make many basic things in it
[17:32] <EoflaOE> OK. Guess what I changed in my blog.

[18:07] <tomreyn> !sysrq is <reply> In an emergency, you may be able to shutdown cleanly and reboot by holding down Alt+PrintScreen and typing slowly, in succession, S, U and B. For an explanation, see https://en.wikipedia.org/wiki/Magic_SysRq_key
[18:08] <tomreyn> !printk
[18:08] <ubot5> If your !tty is full of error messages, you can raise the kernel logging daemons' log level above the default of 4 (KERN_WARNING), e.g. by running "echo 7 | sudo tee -a /proc/sys/kernel/printk". More info at https://wiki.ubuntu.com/Kernel/KernelDebuggingTricks#printk_is_your_friend

[18:15] <tomreyn> !printk is <reply> If your !tty is flooded with error messages, you can limit the kernel logging daemons' log level below the default of 4 (KERN_WARNING), e.g. by running "echo 3 | sudo tee -a /proc/sys/kernel/printk". More info at https://wiki.ubuntu.com/Kernel/KernelDebuggingTricks#printk_is_your_friend and syslog(2)
[18:20] <tomreyn> the diffs there are mostly this: sysrq: suggested pressing all of REISUB when only SUB works (due to the limiter that was introduced years ago to prevent physical attacks). printk: was previously wrong (my mistake), suggested raising the printk when it should be lowered.
[18:35] <tomreyn> https://www.kernel.org/doc/Documentation/admin-guide/sysrq.rst would be the 'official' (but not necessarily newbie friendly) sysrq manual and /etc/sysctl.d/10-magic-sysrq.conf defines the restrictions of which keys are supported on ubuntu systems.
