@Seth

None of the extensions that I used works. And they lower how powerful they could be. You can't get an extension like Tab Groups any more or an stylish speed dial anymore. But wroste of all you can't even get things like the Arc theme or Htitle to work or to patch it to work.

what is this site stackoverflowtr.com/questions/31312588/…

Eliah Kagan

3:03 AM

@TheWanderer I don't know, but it seems sketchy. It uses the Stack Exchange logo in a way that seems to be trying to imply that it is associated with the Stack Exchange network in some way, but it doesn't seem to be. The email address looks like a SE email address. The domain name is registered through a privacy protection service, so it is not easy to find out who has actually registered it. It appears to use guzelhosting.com as its hosting provider.

Both stackoverflowtr.com and www.stackoverflowtr.com resolve to 89.252.186.3, which is on the same network as the IP address in the error message. (That is, it's not actually showing us our IP addresses.) I could think of some possible--if farfetched--innocuous explanations, such as it being a licensed SE 1.0 site that is currently suffering downtime and also a bug that causes wrong error messages to be reported.

But if no one has asked any SE employees about it, I think it's best someone does. Do you want to post on Meta Stack Exchange about it? Or Meta Stack Overflow would probably be fine, too, since the site mimics Stack Overflow specifically.

The site might be a proxy to help people access Stack Overflow who otherwise might have trouble doing so through their Internet connections. (It may be that it is proxying back to us the error page that Stack Overflow actually shows it, when it tries to access it.) If so, that goal seems completely legitimate to me. But I think it's still best that it be looked into.

Any thoughts on how I figure out what gets activated when I press the dim/bright keys, and how I can modify/tweak the behavior? (Using Lubuntu.)

Aaron Hall

5:32 AM

I found this in ~/.config/openbox/lubuntu-rc.xml

<keybind key="C-F10">
  <action name="Execute">
    <command>xbacklight -dec 10</command>
  </action>
</keybind>
<keybind key="C-F11">
  <action name="Execute">
    <command>xbacklight -inc 10</command>
  </action>
</keybind>

But the keybindings are not the same as the media keys on my laptop's keyboard.

They do seem to work similarly, but not precisely the same. When I use the media keys, I can press dim 10 times and the tenth keypress is significantly dimmer, but still viewable. Using the above keybinding (C-F10) the screen is still significantly bright on the 9th keypress but the 10th blacks it out completely.

So that tells me that they are not the same, and that tweaking this file will not help me.

(the media key giving me a very dim but readable screen is probably a lucky rounding error)

Aaron Hall

5:55 AM

I found ~/.config/lxsession/Lubuntu/desktop.conf

nothing directly relevant there though...

Aaron Hall

6:27 AM

in /sys/class/backlight/intel_backlight/:

$ grep [0-9] *
actual_brightness:8
bl_power:0
brightness:8
grep: device: Is a directory
max_brightness:852

tweaking the brightness file changes the screen brightness

Kaz Wolfe

7:00 AM

@Seth Planning on taking Technician ham test sometime this month.

We'll see how it goes.

Aaron Hall

7:37 AM

The XFCE Power Manager (accessed in the GUI panel) has a checkbox that says "Handle display brightness keys" - so I presume this is the thing I'm trying to tweak?

Maybe solved here: bugzilla.xfce.org/show_bug.cgi?id=12062 - I need sleep, can't deal with this anymore tonight...

dessert

@AaronHall Did you already search askubuntu.com/questions/tagged/brightness?

Aaron Hall

@dessert I've been googling all night

dessert

@AaronHall Thinkpad is special some times, I recommend thinkwiki.org/wiki/How_to_get_special_keys_to_work

xmodmap and thinkpad-acpi are the keywords you should look into – after having a good night :)

Aaron Hall

The keys "work" but the functionality is braindead - see the bug report I last linked to. Now I've got to figure out if I can use the "fixed" version...

might have to compile it myself?

dessert

How about you just remap the media keys with xmodmap?

Aaron Hall

7:50 AM

It's more fun to do it the right way.

Well experienced with unattended-upgrades? Please share of your experience with us: askubuntu.com/questions/993470/…

Eliah Kagan

@Arcticooling Do you have the full output of apt-get update -y && apt-get upgrade -y? It seems to me that whether or not the packages it installed had already been downloaded, and possibly some other information that would reveal, may be relevant.

Arcticooling

Sadly I no longer have it... This particular VPS has since been deleted but I remember clearly sitting here surprised asking myself on the behavior I've witnessed, it really was very verbose and long (1-2 minutes of updating and upgrading in comparison to 4 seconds at most in frequent manual upgrades, in most cases...

@EliahKagan

Eliah Kagan

Can you produce similar behavior on a system where you can examine it and try things out? If it cannot be reproduced, then it will probably only be answerable if it turns out to be the expected behavior or an extremely common problem.

Arcticooling

I didn't understand the last sentence you wrote dear Eliah, but anyway sadly I cannot reproduce only because there passed a few months between installing and configuring exactly as I've demonstrated in the question, to execution (as I recall).

hello people

dessert

@UbdusSamad hi!

Ubdus Samad

I have some question related to path , can someone help?

hey there!

dessert

I suppose you mean the PATH variable?

Eliah Kagan

@Arcticooling I just meant, if the problem is specific to anything that was happening on that system that you no longer have, then your question probably cannot be answered. In contrast, if it's a common problem, or if unattended upgrades are actually intended to behave in the way you observed, then it might still be answerable. Since then, an answer has been posted that might shed some light on things--by default, you just get security updates--but you don't have the log file it refers to, do you?

Ubdus Samad

i want write a path for config file that automatically detects your username and and then refers to /home/.myprogram

in layman terms , i have to write a path variable to home/.myprogram , that wroks in every system given that .myprogram folder exists

Eliah Kagan

1:00 PM

@UbdusSamad Usually the best way to do that is to either write:

~/.myprogram

dessert

Do you mean /home/USERNAME/.myprogram?

Eliah Kagan

Or:

"$HOME/.myprogram"

Ubdus Samad

yes , that's excatly what i needed thanks

dessert

you can test whether the directory exists with

Ubdus Samad

alright

dessert

Q: Execute shell commands in Python

I'm currently studying penetration testing and Python programming. I just want to know how I would go about executing a Linux command in Python. The commands I want to execute are: echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-...

python

if necessary, use gksudo or kdesudo respectively to ask for the password.

Eliah Kagan

@UbdusSamad If you package your program, then the package can declare the dependency. Even if there is no repository that provides your program, and users have to install the .deb file themselves, they can still do so in a way that will automatically install its dependencies. In particular, after obtaining the .deb file, they can run:

sudo gdebi your-program.deb

Ubdus Samad

i though of packing it but it's too complicate , i didn't understand much of it

i have a single python file and one dependency

Eliah Kagan

Well, at the opposite end of the spectrum of complexity, you could just tell users what they need to install, in the program's README file. Then you don't have to have the program perform the installation itself.

Seth

@terdon Basically YouTube has a tone of "AI" in place now to detect things that are not "advertiser friendly", but it barely works. Almost every creator I follow now says essentially every video they upload gets automatically demonetized very quickly, then they get their initial view spike, then days later YouTube will manually review it and say the automated systems messed up. But they let people that pull in tons of views do just about whatever they want.

Latest example is this Logan Paul kid (who is a big jerk to begin with) goes to Japan, hugly disrespects their culture, then goes to the "suicide forest", passes all the barriers, finds a dead body, films it, laughs and makes jokes. YouTube manually approves it for the trending page. With a picture of a (slightly blurred) dead body hanging from a tree in the thumbnail. Oh and YouTube also exempts the big name TV shows on YouTube from their advertising policy.

Things like the Tonight Show now get two ads before their videos when youtubers get instantly demonetized.
