Speed test of various dart outputs

Recently, I was playing around with dart and got to know that it supports output of various types. So curiosity arises that which one would be fastest.

So to find out that I used basic hello-world sample

After that, I wrote the bash script


Test Result

On execution of this shell script, I got this

% sh build.sh


Raw

Hello, World!


real 0m0.285s

user 0m0.283s

sys 0m0.077s


Snapshot

Hello, World!


real 0m0.119s

user 0m0.138s

sys 0m0.027s


Executable

Generated: /.../test.exe

Hello, World!


real 0m0.118s

user 0m0.007s

sys 0m0.014s


Aot

Generated: /.../test.aot

Hello, World!


real 0m0.019s

user 0m0.007s

sys 0m0.009s



Observation

Then accumulated these data to process it as a chart that shows the speed test result


Here, 
  • Raw refers to the raw source-code
  • Snapshot refers to the platform independent intermediary code
  • Executable refers to the platform dependent native executable file
  • Aot refers to the AOT file for VM

Conclusion 

The speed in descending order would be like this,

AOT > Executable > Snapshot > Raw

So the execution speed of AOT is fastest whereas Raw is slowest.

Unlock protected blocks in Siemens SIMATIC Step 7

Recently I'd been called by Hindalco's Fabrication Plant division to unlock the protected blocks in Siemens SIMATIC Step 7. They were in need to unlock those blocks since an year because of 1 million Rupees of loss per month. They want to re-program those blocks but it was locked by the man who'd done the setup. From the people working in that department, I came to know that they were trying to call that man (someone from Italy) right here but he's not coming. Actually, what he'd done was that he'd locked some of the blocks and deleted the source file. And Siemens didn't provide any feature to unlock. Department people also told me that even the people working in Siemens don't know how to do it. Being a software engineer I know that any thing can be reverse engineered. So I took up the challenge. How did I unlocked the blocks? The first thing I'd done was searched about this software at Google and read about what is this software all about. Aft...

JS: The complete code example of Crypto.js (DES)

For one of the project I was trying to use crypto.js but I found that the Quick-start Guide have some deficiency in terms of library usage. So I am writing it here as a useful note for memory recap. <script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/tripledes.js"></script> <script> var encrypted = CryptoJS.DES.encrypt("The secret message", "secret_key"); var e_msg = encrypted.toString(); console.log(e_msg); var decrypted = CryptoJS.DES.decrypt(e_msg, "secret_key"); var d_msg = decrypted.toString(CryptoJS.enc.Utf8); console.log(d_msg); </script>

Encode or decode date in 3 characters

I have developed a new way to encode/decode dates within 3 characters by using base-36 format. What is a base 36 format? Base 36 or hexatridecimal is a positional numeral system using 36 as the radix. The choice of 36 is convenient in that the digits can be represented using the Arabic numerals 0-9 and the Latin letters A-Z. In simple language, base-36 format refers to series of 0-9 followed by A-Z characters, i.e., 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ; where each character refers to the position index in series. The concept can also be represents as shown in the below table Series Character Series Character Series Character Series Character 0 0 10 A 20 K 30 U 1 1 11 B 21 L 31 V 2 2 12 C 22 M 32 W 3 3 13 D 23 N 33 X 4 4 14 E 24 O 34 Y 5 5 15 F 25 P ...
