I don't see how that answer using arrays got so many upvotes though

it doesn't fit the question exactly and completely lacks any explanation

1:46 PM

@ByteCommander I found it useful, but you’re right it lacks an explanation.

I am trying to upgrade from Ubuntu 16.04 LTS to 18.04 LTS.

Ugh. Samsung devices.

YOS Samsung devices

have you seen the Note 9?

I have a Galaxy Tab E that thinks the battery is empty when it's full.

oh the tablets

And of course I'm stuck using Odin cuz no Fastboot.

Stupid thing doesn't seem to want to boot now.

Videonauth

can you remove the battery on that device? ?

2:44 PM

Nope.

T-Mobile now gives its subscribers a free Pandora Plus subscription

lol

Odin is insanely powerful though

It may be... if I can get the thing to boot into download mode.

But it just shows the "0%, plug me in!" image.

voldown+home+pwr isn't doing anything?

I never tried using Home.

that's the key combo for download mode

2:45 PM

But Pwr+VolUp/VolDn didn't work.

On a tablet?

Are you sure?

yes

every Samsung

Mkay. I'll try.

the S8 and later use the Bixby button instead because there's no hardware home

Hey, it worked.

but the rest is the same

lol

2:46 PM

Now what do I do... lol.

I don't have the stock images to upload to the device.

plug it in

lol

updato.com/…

@NathanOsman

The exact model is SM-T560NU. I think I found a ZIP with the files in it.

But that's the same ZIP I already tried on the device.

Lemme try booting into recovery.

Well, I find out tomorrow if the old credit card reader on their register is a recognized linux device. It ran on XP, so I can't imagine it's not. Stranger things have happened though.

That was weird. I thought it had completely died for a minute there.

No key combinations were working so I plugged it in and now it claims to at least be charging.

3:32 PM

you tried this one @NathanOsman updato.com/…

3:49 PM

Yup, that exact one.

I'll try the repartition option in Odin though since I did have LineageOS installed on here at one point.

careful with that..

LineageOS won't reparition

it's usually the easiest way to hard brick

Seems I can't anyway.

I don't have a PIT file.

I'll just reflash stock again and see.

hi, i think that i used this command "sudo mv geckodriver /usr/local/bin/" or export path, don't really know which one worked. and now when i type geckodriver in commandline, it uses wrong binary/executable .what do you call these things. How do i replace that geckodriver command would use the correct binary?

or remove the old reference first

RobotHumans

4:08 PM

I used nightwatch to kick it off and it solved all the pathing for me. Might have been either one.

It also kept all the binary stuff in the single nvm, so I didn't need it globally installed and it was portable.

@Scorpion I use multi-timer every week. An idea for next version is to override a single cycle from say 17 minutes stored value to 16 minutes temporary value. Glad you got your algo problem fixed!

Scorpion

7:23 PM

@WinEunuuchs2Unix i don' t know why (even before trying algo) i wasn' t able to open "Connection information" so i reinstalled the system with the same username/password and without formatting any partition. It took more time than a normal installation but i lost only a few programs keeping almost everything like the firefox session.

@WinEunuuchs2Unix I have some idea for multi-timer too, what if instead of an alarm the program performs via some speech synthesizer the name of the timer? and every X second sounds an alarm that can be set only for some timers or all.

The same happen in my other laptop when I upgraded it from Peppermint 8 to Peppermint 9. Something is broken in Ubuntu's last version in regard to bluetooth and no forum has the solution to this problem. One thing I have found is that package bluez-hid is gone and most probably this is the cause...
