Re: Completely Off Topic Chat

Yesterday, I installed Cyanogenmod 12.1 (Android 5.1.1) on my 2.5y/o Samsung Galaxy Express (which never received any meaningful update), and performance is through the roof. A few things are clearly less refined (for example, the auto-adjustment of the display brightness depending on the incoming light is not smooth but in rougher steps), and basic system applications are clearly in the need of more polishing (contacts app, basic Google Calendar widget), but it's quite amazing how much life better(ish) software brings into old crappy phones previously run by fermented 4.1.2 jelly beans. Battery life is as before too; so this will spare me the purchase of a replacement for another year or so smile

Ah and I forgot, something's up with the font rendering. Looks like bad hinting everywhere. :< But that's just nitpickery.

Re: Completely Off Topic Chat

wow.. my usb mouse can be turned on and off by the kitchen stove's electric starter.

With the laptop about 1m from the stove and the mouse plugged in (obviously), when I press the starter button (the one that makes a loud electric "buzz", not those modern "tic-tic" ones) , the mouse turns off, then I press it again, and it goes back on. The laptop does not have to be plugged in.

I'm scared. poltergeist?

It's indeed a testbed since due to all brand phones being entangled by proprietary algorithms, drivers and implementations and the incredibly fragement SoC landscape, getting a CM version ready for a specific model is a very time-consuming task, and it's very impressive that some talented individuals are (still) willing to sink their time into accomodating this frustrating ecosystem.

Re: Completely Off Topic Chat

OK, just read this on the Debian site, regarding writing ISO images to USB drives for booting:

debian.org wrote:

On a Linux machine, simply use the cp command, to copy an image to a USB flash drive:

cp <file> <device>

Two things:
1) The cp command is basically the equivalent of drag-and-drop copying a file from one place to another, right?

2) Assuming my understanding of cp is correct, can you simply boot from a USB that has just had the ISO copied to it? I thought it had to be properly written to the drive using dd or similar...

Re: Completely Off Topic Chat

^ I have no chance to actually try it, but it should work because device files representing block devices can be accessed using regular read(), write(), lseek() etc syscalls which will do their job just fine. For the purpose of writing consecutive blocks to the device with no offset it'll be no different from dd, but as dd gives you much more control over the process (block size, number of blocks, offset, even character set conversions [which makes sense when writing to a character instead of a block device!]) it can be much faster depending on the physical properties of the block device (spinning disk, flash memory with controller in front of it, ...), or actually fit your purpose smile

Try D&D to usb in Thunar with image files - it takes forever compared to cp in a terminal

I've tried cp for writing an iso and it works OK

Re: Completely Off Topic Chat

@pingu -- the laptop doesn't support UEFI, sadly sad

EDIT: Also, if you're using systemd as PID1 and have all your partitions on a single GPT disk then you can mount the root filesystem rw and run without an fstab  cool

yuk!

its openrc big_smile
but It's a btrfs root, so I think it shouldb be  ro at boot time with or w/o systemd.

(but root mounts without the fstab also)
edit: and my fstab is humongous. hehe

Well, I did just what Debian said above with BL RC1 - AMD64 just to see if it worked.  And sure enough, I have booted to BunsenLabs RC1 Live.

The results:

Actually you can boot an ISO that's on the HDD.

I had a btrfs Arch system on a USB stick and I'm pretty sure the arch.conf had "rw" but this may be a feature of Arch's kernel configuration.

Re: Completely Off Topic Chat

I don't know, for some reason I defaulted to that a long time ago and can't remember the reason; but I clearly remember thinking that that was the "correct" thing to do, even though it could work the rw also... hmm

Re: Completely Off Topic Chat

Thing about dd is it overwrites your partition structure, which can be frustrating if you are trying to set persistence up on a USB drive. I know gparted usually doesn't like dd'd USB drives much. I use it frequently but I think partitioning beforehand along with cp would be a better choice in the case of trying to set up a persistence partition.

`cp`, `dd` & `cat` all have exactly the same effect (if the `dd` offset is zero) -- read twoion's post.

Re: Completely Off Topic Chat

I don't know. gparted usually comes up and complains about unreadable partition structure on a USB that I have dd'd an image too. Perhaps it is just that particular drive or something.

Re: Completely Off Topic Chat

^Maybe it depends on whether you wrote to /dev/sdb or /dev/sdb1
ie to the whole device or to a partition on it.
