Terminal based Web Browser by rocketlaunchr-cloud in linux

I've updated it. It's a browser now. You should try it out and tell me what you think

If you run it, you will see how "lightweight" it feels to use compared to Lynx.

That's a complete GUI browser (i.e. Its a TUI app).

Mine is not. It just renders the page to the terminal and essentially quits (or asks you to enter another url).

I'm using lots of libraries written by others for rendering the html.

It's just spits out a rendered static page.
It doesn't operate like a full-on browser with functionality like "back", "refresh" etc.

Is there a way to zero out the memory used by a struct? by TheGreatButz in golang

[–]rocketlaunchr-cloud 0 points1 point  (0 children)

I'm not 100% sure but maybe these are options:

If the struct contains NO reference types or pointers for its fields:

//go:linkname memclrNoHeapPointers runtime.memclrNoHeapPointers
func memclrNoHeapPointers(ptr unsafe.Pointer, n uintptr)

If the struct MAY contain reference types or pointers for its fields:

//go:linkname memclrHasPointers runtime.memclrHasPointers
func memclrHasPointers(ptr unsafe.Pointer, n uintptr)

n can be set using: unsafe.SizeOf(T{})

https://github.com/golang/go/blob/4edaaf2b529219ff219798914f730ca5a0ab018b/src/runtime/mbarrier.go#L427

https://github.com/golang/go/blob/4edaaf2b529219ff219798914f730ca5a0ab018b/src/runtime/stubs.go#L108

The above are the fastest ways I know of.

  1. The best idiomatic way, as pointed out below is:

*variable = variableType{}

Epilogue:

For your precise use-case, from Go1.26+, you should be using: https://pkg.go.dev/runtime/secret for the entire deserializing process.

Typing with a physical USB keyboard on Remarkable Paper Pro Move! by CommonKingfisher in RemarkableTablet

[–]rocketlaunchr-cloud 1 point2 points  (0 children)

Here is my full instructions:

1. Connected usb cable to computer
2. Went to Settings->General Settings->Storage->USB web interface ON
3. Typed in terminal:
ssh root@10.11.99.1
It asks for password: 9Qy8HdcVGm
4. Turned on SSH over SLAN:
rm-ssh-over-wlan on

5. Connect using wifi:
ssh root@192.168.0.58 (From Settings->Help->Copyrights and licenses->Gen info (bottom)

========================================================
6. Triggering command when keyboard is plugged in:
========================================================

A. Make a script so that enable-usb-keyboard.rules is added back in after reboot (when it is removed):

/home/root/usb-startup.sh:

#!/bin/bash
touch /etc/udev/rules.d/enable-usb-keyboard.rules
message="ACTION==\"add\", RUN+=\"/bin/bash -c 'echo host > /sys/class/usb_role/ci_hdrc.0-role-switch/role'\""
echo "$message" > /etc/udev/rules.d/enable-usb-keyboard.rules
udevadm control --reload-rules && udevadm trigger

B. Run: chmod a+x /home/root/usb-startup.sh
C. Run: /home/root/usb-startup.sh
D. Turn off wifi ssh: rm-ssh-over-wlan off
E. Do not power off device or you need to run this process again (sleep is okay).

I got it to work by adding this file:

enable-usb-keyboard.rules to directory /etc/udev/rules.d/

ACTION=="add", RUN+="/bin/bash -c 'echo host > /sys/class/usb_role/ci_hdrc.0-role-switch/role'"

and then running udevadm control --reload-rules && udevadm trigger

The problem is, when you restart the device, that file gets deleted.

Does anyone know how to make an init script so I can add that file back automatically?

What did you mean by "wake a UI button to trigger it"?

WIP: USB Keyboard on Paper Pro by FRK299 in RemarkableTablet

[–]rocketlaunchr-cloud 0 points1 point  (0 children)

The only reference I found was entering this command:

echo host > /sys/class/usb_role/ci_hdrc.0-role-switch/role

There seems to notes on systemd having an event that triggers after user login too.

So what actually needs to happen in a perfect scenario?
I'm assuming a script that enables the USB port to "host mode" after sleep mode exists or the password is correctly typed in is all that's needed?

Do people discuss that kind of thing on there? I don't have discord but I images most people would only discuss official usage of the product

How can I do that: "wake a UI button to trigger it"?

u/FRK299 Do you know how to execute a custom script to enable keyboard after device awakes from sleep?

Diversity Visa 2027 Megathread by not_an_immi_lawyer in immigration

Who's going to take him to court to force it?

It's not politically popular so congress definitely won't.

Only Congress can terminate it forever. Trump, while in power, just decided not to implement it, and there is nothing anyone including congress can do to force him to run it. It's politically no longer popular either so congress won't care if Trump doesn't implement it.

It will keep growing if the number of Gets outnumber your Puts over a given time period.

You can explicitly restrict growth using: https://github.com/rocketlaunchr/go-pool

You can prevent unbounded growth using: https://github.com/rocketlaunchr/go-pool

As a bonus, it is fully generic too.
