Ignore.java: Skip any throwable code

Egit S. — Fri, 16 Oct 2020 04:52:35 +0000

Fuckit.py intro:

FuckIt.py uses state-of-the-art technology to make sure your Python code runs whether it has any right to or not. Some code has an error? Fuck it.

As frustrated man while writing to many SLOC for ignored exception at java like:

try{
    // run.throwable(); 
} catch (Exception ignored){ 
}

meanwhile if should writing to many of should ignored code at runtime as like bellow, how to bypass exception?

int a = Integer.parse("none"); //should skip error, but runtime exception occurred at this line 
throw new JustSampleIgnoreException(); //should skip error, but not executed 
throw new OtherIgnoreException(); //should skip error, but not executed 
int b = 2/0; //should skip error, but not executed 
boolean c = run.call(); //should skip error, but not executed

in traditional java may to use multiple try-catch, like:

try{
    int a = Integer.parse("none"); 
} catch (Exception ignored){ 
} 
try{
    throw new JustSampleIgnoreException(); 
} catch (Exception ignored){ 
} 
try{
    throw new OtherIgnoreException(); 
} catch (Exception ignored){ 
} 
try{
    int b = 2/0; 
} catch (Exception ignored){ 
} 
try{
    boolean c = run.call(); 
} catch (Exception ignored){ 
}

but no. no. no. its not like as expected where with write long code is not cool.

I must simplifying code.

and ahaa, now we can write that to simplified code with small efforts to this:

// 0 as default value when error occurred int a = Ignore.get(()-> Integer.parse("none"), 0); 
Ignore.of(()-> throw new JustSampleIgnoreException(), ()-> throw new OtherIgnoreException()); 
int b = Ignore.get(()-> 2/0, 0); 
boolean c = Ignore.get(()-> run.call(), false);

how it work❓

Remove Linux GRUB from UEFI boot list and keep Windows BCD

Egit S. — Tue, 11 Feb 2020 16:17:02 +0000

UEFI: https://en.wikipedia.org/

ESP: https://en.wikipedia.org/

GRUB: https://www.gnu.org/software/grub/

BCD: https://en.wikipedia.org/

Boot to Windows terminal mode, by typing this at command prompt
shutdown.exe /r /o
other guide https://www.minitool.com/
Rebuild BCD (swapping GRUB to BCD)
bootrec /rebuildbcd
bootsect /nt60 sys
bootrec /fixmbr
if all of that command is not successful, jump to step 3, then back again here to rename old BCD, and retry.
cd /d Z :/EFI/Microsoft/Boot
ren BCD BCD.old
Windows 10 at terminal mode
Make ESP accessible
diskpart
type list disk if any other disk attached, else select disk 0

type list volume to find ESP volume number

select volume number (e.g 4 ) and assign a letter (e.g Z ) as ESP volume alias.
select volume 4
assign letter= Z
exit
Diskpart.exe
Remove Kali GRUB from ESP
cd /d **Z** :/efi
rmdir /r /s **kali**
Done

Bypass premium control di aplikasi Androidnya langitmusik.co.id

Egit S. — Wed, 05 Feb 2020 15:42:24 +0000

Cek aplikasi Langit Musik di Google Play Store:

https://play.google.com/store/apps/details?id=com.melon.langitmusik

Yang melatarbelakangi percobaan ini adalah karena:

Suara streaming yang disajikan sangatlah buruk (noisy)
Tidak bisa memutar lagu dengan durasi penuh pada lagu yang berlabel premium (misal hanya dapat akses 1 menit awal dari total 3 menit)
Banyak iklan , baik di Interface atau saat audio playback
Terlalu Segan untuk berlangganan premium dengan kualitas audio yang masih nanggung

Goalnya:

Suara berkualitas tinggi
Unlock premium playlist agar dapat memutar lagu yang berlabel premium
Hilangkan iklan pengganggu

Action

Download apk dari Play Store atau pull dari handphone.
untuk mempermudah,
rename L̶a̶n̶g̶i̶t̶ M̶u̶s̶i̶k̶ [5̶.3̶.1̶].a̶p̶k̶ menjadi 𝗹𝗺.𝗮𝗽𝗸
Decompile APK dengan ApkTool (https://ibotpeaches.github.io/Apktool/)
apktool d lm.apk
Hasilnya akan banyak Kode Smali yang nantinya akan dimodifikasi.
Modifikasi code:

Kesempatan disini kita hanya perlu mengubah objek UserOffline.

Ubah getter isPremiumAccount() dan isPremium() agar selalu mengembalikan nilai TRUE

Ubah angka 0 (false) pada kursor menjadi 1 (true)

Retrieve forgotten password in Android Studio (IntelliJ IDEA)

Egit S. — Sun, 19 Jan 2020 12:01:21 +0000

No idea, why EYE button is gone?

I was not successfully to seeds plain password from these files, always cryptic with [*] symbol:

IDE log at ~\user\AndroidStudio\system\log\idea.log*

Gradle Task log at ~\projectDir\.gradle\5.4.1\executionHistory\*.bin

and anything with *.bin extension in this gradle directory, e.g. taskHistory.bin

Mehh,

What the HELL with new Intellij version?????

Let’s find the solution, we can use key manager for my issue:

Check it ~\.AndroidStudio3.5\config\*.kdbx
Set master password
Access with KeePass (copy to show only in 12 seconds)
DONE

Assign CA Cert to Android's /system directory for HTTPs decryption

Based on my device lab where tested on Android Virtual Device API v16 – v29, use GAPPs or not.

The main goal is to quickly give a affirmative detail to BE team, when any error occurred.

Fast way for bug spot inspections at production app. Occurred at BE side?, network call, FE logic, or else.

Quotes for Software Qualities Essential

Egit S. — Wed, 17 Jul 2019 13:40:33 +0000

“Quality is essentially about meeting user expectations. Consistently. Reliably. Confidently.”

“Do it fast and fix it later. Or do it slow and you don’t have to fix it at all. ”

“Done means done. End of story.”

“If there is one company that got this guideline right, it’s Apple. Microsoft and Android and Google and most companies out there focus on more. More features. More options. More users. Apple, in contrast, focuses on how little they can do.”

“Pre-written code only becomes an asset when you can re-use it. You can only re-use it if you can find it and understand what it is intended to do.”

“If you see something wrong, do something about it. If you can fix it, do it. Immediately. If you can’t, tell someone who can.”

“The square_root() function shall return the square root of its input for all valid values.” – in a better specification would be: – “The square_root() function shall return the square root of its input for all valid values, and 0 for all invalid values. Valid inputs are positive 32-bit floating point numbers, zero and positive infinity. Invalid inputs are negative numbers, negative infinity, and NaN.”

Recover Lost Deleted “Git stash” using “Git fsck”

Egit S. — Wed, 20 Feb 2019 03:01:50 +0000

1- Open Repository Directory in Terminal / Git Bash.

git fsck | awk ‘{print $3}’ > ids.txt cat ids.txt | xargs git show > logs.txt

2- Then open logs.txt, and find deleted stash id.

example:  
commit a31b0a30701933cfb3d8a55cd4b96320865ae558  
Merge: c465de7 57a3521  
Author: Egit Saputra \  
Date: Tue Feb 19 14:37:29 2019 +0900  
On development: deleted stash test

3- and recover with git stash apply to current active branch.

git stash apply a31b0a30701933cfb3d8a55cd4b96320865ae558

Semantic Versioning for software development

Egit S. — Tue, 12 Feb 2019 04:33:54 +0000

Given a version number MAJOR.MINOR.PATCH, increment the:

MAJOR version when you make incompatible API changes,
MINOR version when you add functionality in a backwards-compatible manner, and
PATCH version when you make backwards-compatible bug fixes.

Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

Semantic Versioning Specification (SemVer)

The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119.

Software using Semantic Versioning MUST declare a public API. This API could be declared in the code itself or exist strictly in documentation. However it is done, it should be precise and comprehensive.
A normal version number MUST take the form X.Y.Z where X, Y, and Z are non-negative integers, and MUST NOT contain leading zeroes. X is the major version, Y is the minor version, and Z is the patch version. Each element MUST increase numerically. For instance: 1.9.0 -> 1.10.0 -> 1.11.0.
Once a versioned package has been released, the contents of that version MUST NOT be modified. Any modifications MUST be released as a new version.
Major version zero (0.y.z) is for initial development. Anything may change at any time. The public API should not be considered stable.
Version 1.0.0 defines the public API. The way in which the version number is incremented after this release is dependent on this public API and how it changes.
Patch version Z (x.y.Z | x > 0) MUST be incremented if only backwards compatible bug fixes are introduced. A bug fix is defined as an internal change that fixes incorrect behavior.
Minor version Y (x.Y.z | x > 0) MUST be incremented if new, backwards compatible functionality is introduced to the public API. It MUST be incremented if any public API functionality is marked as deprecated. It MAY be incremented if substantial new functionality or improvements are introduced within the private code. It MAY include patch level changes. Patch version MUST be reset to 0 when minor version is incremented.
Major version X (X.y.z | X > 0) MUST be incremented if any backwards incompatible changes are introduced to the public API. It MAY include minor and patch level changes. Patch and minor version MUST be reset to 0 when major version is incremented.
A pre-release version MAY be denoted by appending a hyphen and a series of dot separated identifiers immediately following the patch version. Identifiers MUST comprise only ASCII alphanumerics and hyphen [0-9A-Za-z-]. Identifiers MUST NOT be empty. Numeric identifiers MUST NOT include leading zeroes. Pre-release versions have a lower precedence than the associated normal version. A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version. Examples: 1.0.0-alpha, 1.0.0-alpha.1, 1.0.0-0.3.7, 1.0.0-x.7.z.92.
Build metadata MAY be denoted by appending a plus sign and a series of dot separated identifiers immediately following the patch or pre-release version. Identifiers MUST comprise only ASCII alphanumerics and hyphen [0-9A-Za-z-]. Identifiers MUST NOT be empty. Build metadata SHOULD be ignored when determining version precedence. Thus two versions that differ only in the build metadata, have the same precedence. Examples: 1.0.0-alpha+001, 1.0.0+20130313144700, 1.0.0-beta+exp.sha.5114f85.
Precedence refers to how versions are compared to each other when ordered. Precedence MUST be calculated by separating the version into major, minor, patch and pre-release identifiers in that order (Build metadata does not figure into precedence). Precedence is determined by the first difference when comparing each of these identifiers from left to right as follows: Major, minor, and patch versions are always compared numerically. Example: 1.0.0 < 2.0.0 < 2.1.0 < 2.1.1.

When major, minor, and patch are equal, a pre-release version has lower precedence than a normal version. Example: 1.0.0-alpha < 1.0.0. Precedence for two pre-release versions with the same major, minor, and patch version MUST be determined by comparing each dot separated identifier from left to right until a difference is found as follows:
- identifiers consisting of only digits are compared numerically and identifiers with letters or hyphens are compared lexically in ASCII sort order.
- Numeric identifiers always have lower precedence than non-numeric identifiers.
- A larger set of pre-release fields has a higher precedence than a smaller set, if all of the preceding identifiers are equal.
Example: 1.0.0-alpha < 1.0.0-alpha.1 < 1.0.0-alpha.beta < 1.0.0-beta < 1.0.0-beta.2 < 1.0.0-beta.11 < 1.0.0-rc.1 < 1.0.0.

Route AppCenter Distribute SDK to specific Release Group

Egit S. — Thu, 10 Jan 2019 08:29:09 +0000

Noted because no textual official documentation found. Free to update.

One of the CI.

Preword:

Appcenter
Appcenter Distribution – allowing me to set up the in-app auto update to release group.

But for But,

There is as flexible SDK, we can point update check to the specific group as we can prepare. With this, we can get the in-app auto-update without login as tester collaborator.

import com.microsoft.appcenter.utils.storage.SharedPreferencesManager;

...

SharedPreferencesManager.initialize(this);
SharedPreferencesManager.putString("Distribute.distribution_group_id", "***REPLACE WITH GROUP-ID HERE***");
