Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Conversion from tm struct and String into time_t
Redshift has code to calculate that locally which I use in my sunrise light project
-
Does XFCE have a night light?
FWIW, Linux Mint XFCE comes with Redshift.
- How to setup blue light filter?
-
If you use your PC for long hours, use Eye Saver app to protect your eyes.
Other options include f.lux and redshift.
-
blocking blue light
There is Redshift: https://github.com/jonls/redshift

How do you build circuits?
eg for this project my available inputs were intermittent 12v power, bluetooth, and the current time and location; and the desired output was 3× high current low-side switches that produced 12v RGB PWM corresponding to the colour temperature and brightness of the sky - so we need a bluetooth microcontroller, battery backup to keep time when 12v is absent, some battery management which wanted 5v in, a 12v buck to feed it, some MOSFETs, and redshift or similar code to plug into things.

How can I use an Arduino board to control LEDs so it imitates the sunlight color temperature throughout the day?
I just added redshift as a submodule to handle the GPS location + UTC time to color temperature conversion.
-
what's the alternative for linux like F.lux for windows for yellow light and brightness for screen?
But I still use redshift and prefer it over f.lux. I am on cell and this is first result so double check https://github.com/jonls/redshift
-
Linux (Debian) equivalent of DimScreen on Windows or MonitorControl on MacOS?
Anyway, for dimming screens with overlays (or gamma alteration), Redshift seems to have a -b option.
-
How do you even install redshit on windows ? (screen temp program)
The instructions are super confusing to me. Here's the github :https://github.com/jonls/redshift

Show HN: Multi-monitor KVM using just a USB switch
Apologies. I hate when people do that as well.
In addition to the other links posted, ddcutil.org has some more good info: https://www.ddcutil.com/#introduction
- Scrollbars Are Becoming a Problem
- CEC over DisplayPort

Connecting a Display Port 1.4 graphics card to the Dell thunderbolt dock WD22TB4
Most monitors have a Virtual Control Panel (VCP), which implements features defined in the Monitor Control Command Set (MCCS). This is a VESA standard. You can find the Input selection command in table 8-10. You send these commands over an I2C bus called Display Data Channel/Command Interface which is yet another VESA standard. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar

Opinions on functional & performance requirements for a desktop TB/USB4 AIC
The protocol is called DDC , it's a VESA standard. In there, it's called VCP features. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar note how all three mention input selection.

TIL there are apps that can control your monitor without touching the buttons on it
ddcutil (a command-line tool, and what most UI tools are based on)
-
'monitorctl' cli tool to control brightness, contrast and volume of external monitors on linux
A related non rust tool (that also has an optional GUI) is ddcutil. How does this compare to that?
- I built a widget to adjust the brightness of external monitors
-
Brightness issue
I've also used ddcui: https://www.ddcutil.com/#introduction, available as an AUR package: https://github.com/rockowitz/ddcutil. This has a nice GUI: https://www.ddcutil.com/screenshots/ddcui_features.png and works on everything I've tried it on out of the box.
What are some alternatives?
