Pyhton: playwright to get audio url stream

There are many tool to find url audio stream from radio station's page, here are a few list:

1. playwright
2. Selenium
3. Puppeteer

To use Wget to find url audo on statik and simple web  

$ wget --spider -r -l 5 -nv -w 1 --no-clobber -A .mp3,.m3u8 "https://www.example.com/audio/stations" 2>&1 | grep -E '\.(mp3|m3u8)$' | awk '{print $3}' | sort -u > out_audio_urls.txt

Install playwright on debian with virtual environment:

Android java: improving application screen form factor

In AndroidManifest.xml we can define screen form factor to used.

These are the options

1. "unspecified" : The default value. The system chooses the orientation. The policy it uses, and therefore the choices made in specific contexts, might differ from device to device.
2. "behind" : The same orientation as the activity that's immediately beneath it in the activity stack.
3. "landscape" : Landscape orientation (the display is wider than it is tall).
4. "portrait" : Portrait orientation (the display is taller than it is wide).
5. "reverseLandscape" : Landscape orientation in the opposite direction from normal landscape. Added in API level 9.
6. "reversePortrait" : Portrait orientation in the opposite direction from normal portrait. Added in API level 9.
7. "sensorLandscape" : Landscape orientation, but can be either normal or reverse landscape based on the device sensor. The sensor is used even if the user has locked sensor-based rotation. Added in API level 9.
8. "sensorPortrait" : Portrait orientation, but can be either normal or reverse portrait based on the device sensor. The sensor is used even if the user has locked sensor-based rotation. However, depending on the device configuration, upside-down rotation might not be allowed. Added in API level 9.
9. "userLandscape" : Landscape orientation, but can be either normal or reverse landscape based on the device sensor and the user's preference. Added in API level 18.
10. "userPortrait" : Portrait orientation, but can be either normal or reverse portrait based on the device sensor and the user's preference. However, depending on the device configuration, upside-down rotation might not be allowed. Added in API level 18.
11. "sensor" : The device orientation sensor determines the orientation. The orientation of the display depends on how the user is holding the device. It changes when the user rotates the device. Some devices, though, don't rotate to all four possible orientations, by default. To use all four orientations, use "fullSensor". The sensor is used even if the user locked sensor-based rotation.
12. "fullSensor" : The device orientation sensor determines the orientation for any of the four orientations. This is similar to "sensor", except this allows for any of the four possible screen orientations regardless of what the device normally supports. For example, some devices don't normally use reverse portrait or reverse landscape, but this enables those orientations. Added in API level 9.
13. "nosensor" : The orientation is determined without reference to a physical orientation sensor. The sensor is ignored, so the display doesn't rotate based on how the user moves the device.
14. "user" : The user's current preferred orientation.
15. "fullUser" : If the user has locked sensor-based rotation, this behaves the same as user, otherwise it behaves the same as fullSensor and allows any of the four possible screen orientations. Added in API level 18.
16. "locked" : Locks the orientation to its current rotation, whatever that is. Added in API level 18. 

Warning: To improve the layout of apps on form factors with smallest width >= 600dp, the system ignores the following values of this attribute for apps that target Android 16 (API level 36):

1.     portrait
2.     landscape
3.     reversePortrait
4.     reverseLandscape
5.     sensorPortrait
6.     sensorLandscape
7.     userPortrait
8.     userLandscape 

To create variant for table,  Goto main activity, on your main activity dropdown select "create table qualifier", it will create copy of main activity that require to modify to match tablet out. the layout is on layout -> main_activity -> main_activity.xml (sw600dp).

In case you want to lock phone to use portrait, delete main_activity.xml (land), you need to remove android:screenOrientation from AndroidManifest.xml. To make it consistent, this is sample of code in java for your main activity

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // 1. Enable edge-to-edge for Java Activities
        // You need to import androidx.activity.EdgeToEdge;
        EdgeToEdge.enable(this);
        super.onCreate(savedInstanceState);
        // Fragment
        // layout portrait or lanscape?
        // portrait my_fragment_container
        // langsacpe fragment_config_container, fragment_main_container
        setContentView(R.layout.activity_m); // general, let system choose between portrait and landscape
        // Check if landscape (two-pane) layout is active
        View config = findViewById(R.id.fragment_config_container);
        View main = findViewById(R.id.fragment_main_container);
        isTwoPane = (config != null && main != null); // already checked not null
        // Conditional Orientation Lock
        if (!isTwoPane) {
            // If single-pane (phone), force portrait before fragment transactions
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }
        if (isTwoPane) {
            // dual-pane
            setFragment(R.id.fragment_config_container, new FragmentConfig());
            setFragment(R.id.fragment_main_container, new FragmentMain());
        } else {
            // single-pane
            // all phone must use this activity_m.xml (land)
            setFragment(R.id.my_fragment_container, new FragmentMain());
        } 

Immediately, lock screen for single pane (phone) to portrait, i.e. setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Android java: Releasing resource Activity/Fragment <-> AndroidViewModel <-> MyController

Activity/Fragment <-> AndroidViewModel <-> MyController

MyController will hold

1. Executor
2. MediaController 
3. Network access
4. Database access
5. Application context for above operation  

Proper way to clear the resource

1. Executor
           // MyAndroidViewModel onClear() has been reached
        if (myExecutor!=null) {
            myExecutor.shutdown();
            myExecutor = null;
        }
2. Media Controller
           if (myMediaController!=null) {
            myMediaController.releaseMediaSession(); // MUST BE CLEAR
            myMediaController = null;
        }
3. Network access
           myGetRadioLogo=null;
4. Database access  
           myDBAccess=null;
5. Application context
           appContext=null; // MUST SET NULL AT ONCLEAR

Fail to release these resources may lead to memory leak

Fail to release resource with not properly sequence may lead application crashed, this crash can be found on logcat.  

Debian 13: part 3 participate your vps, cofigure your vps as tor relay/exit

There 2 type of TOR network you an configure on VPS

1. Relay
2. Exit

Minimum system requirement:

1. CPU 1 vcpu
2. Ram 512MB (1GB Recommended)
3. Bandwidth 10 Mbps in & out
4. Traffic 100 GB in & out
5. Disk 200 MB 
6. swap not mention (better twice RAM size) 

Enable Debian 13 auto upgrade

# apt install unattended-upgrades
# systemctl enable unattended-upgrades
# systemctl start unattended-upgrades


Installing tor packages and key

1. Install require software
   # apt install apt-transport-https gnupg
2. Create /etc/apt/sources.list.d/tor.list with:
   deb     [signed-by=/usr/share/keyrings/deb.torproject.org-keyring.gpg] https://deb.torproject.org/torproject.org trixiemain
deb-src [signed-by=/usr/share/keyrings/deb.torproject.org-keyring.gpg] https://deb.torproject.org/torproject.org trixie main
3. installing key and tor
   # wget -qO- https://deb.torproject.org/torproject.org/A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc | gpg --dearmor | tee /usr/share/keyrings/deb.torproject.org-keyring.gpg >/dev/null
# apt install tor deb.torproject.org-keyring
# apt install tor

Note: you can browse using browser https://deb.torproject.org/torproject.org/ if A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc has change 

TOR relay 

TOR relay consider safer way to contribute to TOR network, It does not act as critical point entry or exit network. 

configure your tor relay /etc/tor/torrc:

Nickname    myNiceRelay  # Change "myNiceRelay" to something you like
ContactInfo your@e-mail  # Write your e-mail and be aware it will be published
ORPort      443          # You might use a different port, should you want to
ExitRelay   0
SocksPort   0 

Enable and restart tor service

# systemctl enable tor
# systemctl restart tor

TOR Exit

Exit TOR may have high security risk including breaking law. you need to carefully decide your county's rules where your vps located. Some country has aware with Exit TOR node.  

install unbound dns resolver

1. install unbound
   # apt install unbound
2. configure dns resolver using localhost
   # cp /etc/resolv.conf /etc/resolv.conf.backup
# echo nameserver 127.0.0.1 > /etc/resolv.conf
3. protect resolver from change
   # chattr +i /etc/resolv.conf
4. edit unbound configuration
   server:    ...
    qname-minimisation: yes
    ...
5. enable and restart unbound
   # systemctl enable unbound
# systemctl restart unbound

Definitely do not use torproject.org as a domain name for your reverse DNS

configure your tor relay /etc/tor/torrc:

Nickname    myNiceRelay  # Change "myNiceRelay" to something you like
ContactInfo your@e-mail  # Write your e-mail and be aware it will be published
ORPort      443          # You might use a different port, should you want to
ExitRelay   1            # it is exit relay
SocksPort   0 

Enable and restart tor service

# systemctl enable tor
# systemctl restart tor

Wait until tor network recognize your node.

Done, now you are on track to run vps as tor volunteer.

Windows 11: installing windows 11 and post configuration part 2

Copy your windows iso into Ventoy USB data partition, not in boot partition. you can create folder windows and put iso file in this directory. Ventoy boot manager will find any bootable iso file in Ventoy data partition. see here to create Ventoy USB boot manager https://dedetoknotes.blogspot.com/2025/09/debian-13-using-ventoy-to-create.html

Before you starting to. install in computer/laptop, in my case axioo Hype 5 x6, download wifi driver, it does not have Ethernet port. if you have Ethernet port, download it. if those driver are zip, extract it, and put in Ventoy data directory. e.g. after you extract file in directory wifi, copy directory wifi into Ventoy data -> driver (optional you need to create). 

To start installing windows 11, insert Ventoy USB that has been prepared before and turn your laptop/pc on. it will show which iso you want to run. 

Note: you need to change UEFI boot order if you use used nvme contains working os!

installation windows is straight forward. if you use iso windows 11 24h2 or after, you need outlook account or Hotmail if you come from generation like me ☺️. when it reach internet connection, install driver that has been provided in Ventoy USB data.

if you use windows 11 iso 23h2 or before, you can bypass it by pressing shift+f10 when windows ask internet connection and run:

OOBE\BYPASSNRO

after you enter that command, it will reboot/restart. now you can choose no connection internet and create local account. 

after finish, login into windows, go to system, update and check additional update to update hardware driver. update all driver, include printer you want to use. 

if you need software/driver for printer and scanner, find it in windows store and install it. for HP printer inktank multi function, you need to update windows driver. windows said it is optional, but in my opinion it is bridge between system and HP Smart from windows store.

Tweak your windows post installation (optional)

Turning off fast boot 

turn off fast boot if you want to dual boot later. if it is turn on, windows will never unmount driver/partition they use. any files and folder created from second os will be thread as not valid. it will setback to position when windows shutdown. turn off fast boot will completely unmount any drive/partition.

I usually prefer for performance, go to control panel -> system -> advanced system settings or run sysdm.cpl. select performance.

Set fix windows virtual memory

I also use fix windows Virtual Memory / swap. from sysdm.cpl, select Virtual Memory Settings.

select custom size. if your memory less then 16GB, the value is equal twice of your physical ram. e.g physical ram 8GB, use 8GB, if ram 4GB use 8GB. if you use 16 or above, put this value 4GB. set minimum and maximum with the same value e.g 4GB in my case axioo Hype 5 x6 with ram ddr5 2x8GB.

note: there is performance penalty when you windows run out of physical ram and use swap into virtual memory, i.e your nvme. event it is fast as close to pci speed, it will slower due to overhead swap ram to disk vice versa and also reduce your nvme life! when you need bigger memory, do upgrade instead of make virtual memory bigger.

Monitor your NVME

install CrystalDiskInfo to monitor NVME, don't let run your nvme run on high temperatur for long time wihtout proper heat sink or cooling system, especially of laptop. In my option running nvme on 70°C or above on a long time may damage your nvme's chips.

Using windows encryption (bitlocker) on nvme may arise higher activity and increase temperature. if it is not urgent, don't use it.  when it bitlocker turning on or turning off, it will start encrypt or decrypt your entire harddisk. in Task manager it will show 100% harddisk utilization and at CrystalDiskInfo the temperature may arise

Adding Local Account 

for windows with link account to outlook or Hotmail, here is how you create local account.

1. run cmd as administor 
2. command to create local user
   > net user myname mypassword /add
3. to set user myname as administor 
   > net localgroup administrators myname /add
4. to verify user 
   > net user
5. sign out and try sign in with local account.

note; you can remove account linked to outlook or Hotmail using local administrator user created before. 

Windows 11: clean install preparation part 1

This is documentation when I need to reinstall windows 11, because of nvme damage (overheat). It is Axioo 5 hype X6 with Ryzen 6600h. It has windows 11 installed, and this laptop does have ethernet port. 

Download ISO should I download

1. 25h2: shift+f10 keyboard input has been disabled (download from archive.org/)
2. 24h2: shift+f10 keyboard input has been disabled (download from archive.org/)

I did not try 23h2 version, it will take more time to install and laptop must be ready for studying.

During installation shift+f10 will bypass network configuration, you have to run

oobe\bypassnro

after terminal. it will restart installation.  

If you want to use 25h2 and 24h2, download the driver from laptop provider website. in my case download from driver.axiooworld.com, just network driver, others can be installed at the end of windows 11 installation. If you want to use only Windows skip step below, and go to part 2 installation windows.

This below instruction uses other pc/laptop to prepare nvme disk. 

Optional but recommended for dual OS, create EFI System partition (ESP) for new nvme, the minimum size is 500MB. this is step on debian using gparted.

Put a nvme, into nvme ssd/nvme external usb, and connect it your laptop.

Check your nvme

Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

this is mount point /dev/sda.

I use this schema

1. 500 MB ESP (FAT32 Flag boot and esp)
2. 120 GB Windows system (NTFS)
3. 30 GB Data Windows (NTFS
4. 80 GB Debian / (ext4)
5. 4 GB swap (swap)

 To use GParted to create partition on nvme (Be careful not select wrong disk)

1. Open GParted
2. Select Gparted -> devices -> /dev/sda, If it a new device (never use), you need to create parititon table, Device -> Create partition table, choose 'gpt'
3. select unallocated space, and create EFI System Partition (ESP) for boot loader
       File System: FAT32
       Size: At least 300 MiB (recommended 500 MiB for future needs)
       Label: Optional, but you can name it "EFI". 
4. Apply all operation 
5. Now you can manage flag for ESP, select partition EFI,right click -> Manage Flags -> check 'boot' and 'esp' 

Note: if you try to create new partition in brand new nvme (never used), it will reported No Partition table found, it is really a new device.

Just, to create the partition, the Adata legend 710 heat sink feel a bit warmer.

You can not download windows 11 multi iso from windows https://www.microsoft.com/en-us/software-download/windows11. You can continue with windows 11 installation, it will put boot loader in EFI system partition (ESP) and next you want to install Debian.

Using private Private DNS in Android 9 and above for more for security

Sometimes we disappointed to use isp's dns resolver. whatever the reasons, since Android 9 (Pie) and later versions, user can change his/her android phone to use Private DNS. Only one DNS server can be used, it does not support multiple DNS resolver!

Axioo Hype 5 X6 Ryzen 6600h, blank screen but laptop running

 Symptoms;

1. laptop on, fan on, indicator on
2. no any image nor characters appear on screen, backlight on
3. ctl-alt-del is working
4. can not enter bios 

Steps to diagnostic

How to remove static voltage

1. open back cover you need screw driver + small
2. remove all rams
3. remove all nvme
4. remove / unplug battery 
5. Press and hold power button at least 15 seconds
6. reconnect/plug battery 

Check ram

1. clean ram connector with eraser 
2. put in a ram in slot 1
3. turn on laptop, and see what screen show, usually it will enter uefi/bios settings
4. if not ram not detected, blank screen or not appear in uefi, turn of laptop and put ram into another slot. repeat until no more slot to try. if it still does not detected, ram fail/damage.
5. If ram detected in another, it may something wrong with previous slot, check connector and clean if necessary. if still can detect, slot failure.
6. repeat step 2 with another ram.

Check nvme (or sata)

1. clean vnme connector with eraser 
2. put nvme in the slot
3. turn in laptop
4. if it does not go to os or uefi, turn off and move vnme to another slot if available.
5. if no more slot can detect nvme and start uefi/os, nvme is failure/demage

Android java: using DataLive for orientation change

I test it in Android 10 xiaomi mia2

What will happen when orientation change e.g. screen change or language change?

the object in activity will be destroyed. here is the sequence:

• after orientation change
  V  onPause
  V  onStop
  V  onDestrouy
• after flusing all data
  V  onCreate
  V  onCreate myClass :null
  V  MyClass constructor
  V  onCreateView myClass.getRandom
  V  onStart
  V  onResume 

At xiomi mia2, override public void onConfigurationChanged(Configuration newConfig) method did not called at all during screen orientation change, not appearred in logcat. except, you put android:configChanges in your layout.

Base on the android behave, these are the solution can be used to keep the object during configuration change:

1. Local persistence to handle process death for complex or large data. Persistent local storage includes databases or DataStore.
2. Retained objects such as ViewModel instances to handle UI-related state in memory while the user is actively using the app.
3. Saved instance state to handle system-initiated process death and keep transient state that depends on user input or navigation. 

ViewModel is recommended used for today an future, These are some options:

1. ViewModel    Holds UI data & logic    Core architecture component
2. ComputableLiveData (Deprecated)
3. MediatorLiveData    Combines multiple LiveData sources    Merging streams
4. MutableLiveData    Observable, mutable data    UI updates
5. SavingStateLiveData    LiveData with saved-state persistence    Restore after process death 

Comparison between AndroidViewModel vss ViewModel

AndroidViewModel	require Context for DB, prefs, etc.	gemini: Avoid if possible. Only use when you absolutely need Context. violates a core principle of good architecture: separation of concerns and testability.
ViewModel	UI logic without needing Context	Network requirement may use this, it does not need context

NOTE: Don’t store Activity or Fragment in VieModel nor AndroidViewModel! 

These are the java code for education, first text using direct access to object in activity, and second text using live data and AndroidViewModel. this code used AndroidViewModel, because I need application's context to access sqlite.

Android Studio: using Logcat and filter

 

Level	Priority	Use Case
Log.v()	Verbose (V)	Everything. Detailed tracing of functions, variable values, lifecycle events.
Log.d()	Debug (D)	General debugging messages useful for development.
Log.i()	Info (I)	Important business logic messages, typical user actions, system state changes.
Log.w()	Warn (W)	Use of deprecated APIs, non-critical errors that can be recovered.
Log.e()	Error (E)	Critical errors that cause a failure or stop a feature from working.
Log.wtf()	Assert (A)	What a Terrible Failure. Reserved for conditions that should never happen.

Option to filter in Andorid Studio Logcat

1. tag: Filters messages by a specific log tag.
   Example: tag:MyActivity
2. level: Filters messages at the specified log level or higher. Levels include VERBOSE (V), DEBUG (D), INFO (I), WARN (W), ERROR (E), and ASSERT (A).
   Example: level:ERROR (shows ERROR and ASSERT logs)
3. process: Filters messages by the process name or process ID (PID).
   Example: process:1234 or process:com.example.app
4. age: Filters messages by how recent they are. The value is a number followed by a unit of time: s (seconds), m (minutes), h (hours), or d (days).
   Example: age:5m (shows messages from the last 5 minutes)
5. is: Can be used with crash to filter only crash logs.
   Example: is:crash
6. package: A convenient shortcut to filter logs only from the currently running application's package. 

Logical operation can be use in Logcat Filter

1. && (AND): Requires both conditions to be true.
   Example: package:mine && level:WARN
2. | (OR): Requires at least one condition to be true.
   Example: tag:Tag1 | tag:Tag2
3. - (NOT/Exclude): Excludes logs matching the condition. Place the hyphen before the key.
   Example: -tag:ExcludedTag

Example usage Logcat filter:

1. package:mine level:INFO "user data" -tag:network
2. tag:MyTag && level:DEBUG || is:crash

You can use beans to map the result, or manually process the csv files. for data size bigger then 1 millions, there is deference about 1 second, it is better to manually process. Here are code to test, before you use it in production. Feel free to change any the code to meet your requirement.

Debian 13: increase nvme life time, and how to check its health with additional ssd sata

We move some mount point to cheaper device sata ssd (sata ssd is cheaper then nvme)

1. /home
2. /var
3. /tmp 

for small ram consider to move swap disk into sata ssd. for big ram (equal or more then 16GB), you may keep it on nvme, in case the os require to use swap, it will use nvme for best performance. It is for Debian or other linux distribution, not for windows.

"Recommendation: Since the error occurred so early, it's highly likely to be a dead-on-arrival (DOA) or early life failure. The drive should be considered unreliable and immediately replaced under warranty. Do not store critical data on this device."

Gemini recommendation for "smartctl -x /dev/sda" (copy paste all output):

 "The drive's SMART overall-health self-assessment test result: PASSED and the zero count on critical wear-related attributes (like Reallocated Sector Count) suggest the media is physically healthy and not currently failing due to wear.

However, the high number of "Device Fault" errors that occurred early in the drive's life, combined with the anomalous self-test log, indicates a potential instability issue."

Chatgpt.com commenting for the output:

"Verdict: Your RX7 240 GB SSD is fully healthy and nowhere near worn out.

Your RX7 240 GB SSD is healthy, low-wear (~2.8 TBW), and has ~95 % lifespan remaining." 

 Chatgpt.com explanation about the errors:

"What those “Errors” really are

• These are entries in the SMART Extended Error Log, not current hardware problems.
• Your log shows 6 errors, all at power-on lifetime: 0–1 hours.
  That means: they happened right when the drive was brand new or initializing — years ago.
• Since then (643+ hours of runtime), no new errors have been logged."
