Telur Pete Rebus Tumpang Nasi?

 Ambil mangkok tahan panas,

 masukkan dua telur ke dalamnya, (kulitnya nggak ikut ya),

 masukkan pete sesuai selera,

 masukkan bersamaan dengan menanak nasi di rice cooker,

 tunggu setengah jam hingga 45 menit.

 Selama menunggu akan ada bonus bau harum tercium di seluruh bagian rumah, :)

 Bersamaan dengan nasi yang matang, kita sekaligus mendapatkan lauk.

 Praktis, :)

Unlock Tracktion for Mac (redeem)

 I bought Behringer Xenyx QX1202usb, a wonderful cheap small mixer.

 Turn out that it has serial number or code in it case. It allowed us to get full access for Tracktion software.

 So I follow the instruction: register, got confirmation email, download.

 When running the software it prompt me to choose between unlock or continue trial. Of course I went to unlock route. But when I type my email and password it get error.

 Tinkering with it for some hours, the truth's hit me. Tracktion gave me T5 software link in my email. The license is for T4.

 So I download T4 manually (re-register with the same email address). Installed , ran , unlocked, and... succeed.

 And guess what, after I unlocked T4, I ran T5, and it suddenly became unlocked, a little surprise bonus..., :)

Ngalamania Generasi Baru

 Apa beda 'umak isa apa', 'aku ora nggawa libom', 'adepes rotom ku lagi mogok', 'umak apa wis nakam?', 'wis beli soak?'

 dengan

 'lesek lop', 'ewul', 'aro utem', 'siw utuk?', 'kawa sanap'

 ?

 Kelompok pertama adalah  bahasa walikan khas aremania jaman dulu, kelompok kedua adalah bahasa walikan aremania jaman sekarang yang sering saya baca di pasting media sosial.

 Apa bedanya?

 Bahasa Ngalam kelompok pertama, yang merupakan generasi awal bahasa walikan; hanya membalik kata-kata serapan; kata-kata non bahasa jawa, misal bahasa indonesia. Konon dulu digunakan sebagai sandi, karena penjajah sedikit banyak tahu bahasa indonesia dan tidak tahu bahasa jawa maka penggunaan bahasa indonesia dibalik. Ada beberapa pegecualian seperti kata 'beli' karena jika dibalik tidak dapat dibedakan antara 'ileb' dan 'ilep', maka kata 'beli' tetap dipakai secara normal tanpa dibalik.

 Karena bahasa ini merupakan bahasa yang berkembang  dan masyarakat pun berkembang. Dengan seiring perkembangan teknologi dan lahirnya generasi baru Ngalamania, bahasa ini juga berkembang, meski menurut saya menuju ke arah yang membingungkan.

 Eh, kenapa?

 Membingungkan karena generasi baru pemakai bahasa ini membalik kata-kata secara membabibuta. Tentu saja sejak awal memang tidak ada kaidah resmi bahasa walikan. Namun jika kita membalik semua kata termasuk bahasa jawa, percakapan akan menjadi mengerikan (setidaknya bagi saya) karena otak dipaksa menganalisis dan membalik secara nonstop.

 Dari dua kelompok contoh di atas, kelompok pertama lebih mudah dipahami (menurut saya), dan saya sudah familier dengan model pembalikan seperti itu selama bertahun-tahun.

 Kelompok kedua? Well, sepertinya saya harus mengkalibrasi otak dulu, :)

#edisiError

Kebijaksanaan Lokal.

 Kenapa orang tua jaman dulu melarang kita menyapu rumah di malam hari? Kalaupun terpaksa harus menyapu, sapuannya tidak boleh diarahkan keluar melainkan ke dalam untuk dibuang esok harinya?

 Mungkin (hanya kemungkinan), hal itu untuk menghindari barang-barang kecil berharga semacam anting-anting atau kalung emas tipis, atau simcard, yang tak sengaja terjatuh ke lantai ikut tersapu keluar. Karena pada malam hari disapu ke arah dalam, maka misal barang-barang berharga ikut tersapu, kita masih akan dapat mencarinya esok hari, saat cahaya terang, saat akan membuang hasil sapuan di malam kemarin.

Aturan

 Diciptakan untuk ditaati

 ... dan dilanggar.

 Tentu saja pelanggar aturan akan dikenai sanksi.

 Sanksi terhadap pelanggar seharusnya ada di tiap aturan

 Tetapi beberapa aturan dibuat tanpa sanksi untuk pelanggar, entah kenapa

Miss Lay.

 Baca komen seperti  "Permainan gitar Eross pecah banget...." di Youtube, hati langsung panas.

 Berani-beraninya menghina sang maestro, sana, ke comberan sana, tempat asalmu, ...

 Eh, tunggu...

 Itu bukan hinaan, itu pujian...

 Pecah? Pujian?

 Yeah, beberapa dari kita sering menggunakan kata tak pada tempatnya, :)

 Penggunaan kata 'pecah' sebagai pujian datang dari Maia Estianty saat menjadi juri The Remix.

 Tentu saja penggunaan kata 'pecah' di dunia DJ atau remix sangat cocok; merujuk pada sunyi yang lambat laun menjadi semakin ramai seiring dengan penumpukan nada-nada sampling yang makin banyak, tempo yang makin cepat dan diakhiri dengan sebuah hentakan..., pecah..., 

 OK, itu pujian, bagaimana kalo kata 'pecah' digunakan di permainan gitar. Yeah, kami menganggap kata pecah sebagai kata berkonotasi buruk; merujuk pada suara gitar yang seharusnya clean namun karena setting yang buruk jadi terdengar 'brebet' atau 'pecah'.

 Bukannya efek gitar Telecaster-nya Eross mempunya karakter pecah?  Ehm, EDrive-nya Eross, seperti namanya, 'drive', hanya bertugas sebagai booster saat permainan lead, bahkan kalo kita lihat di penampilan live, Eross jarang sekali menggunakan stompbox, dia memainkan knob volume untuk efek crunch atau crisp. Jika  ingin suara clean, dia mengecilkan volume gitarnya.

 Suara Telecaster Eross 'pecah'? Well, lebih baik pakai kata crunchy, crispy, ..., lebih diterima oleh banyak gitaris, :)

3D Animation of 2D Diffusion Equation using Python, Scipy, and Matplotlib

 I wrote the code on OS X El Capitan, use a small mesh-grid.  Basically it's same code like the previous post.

 I use surface plot mode for the graphic output and animate it.

 Because my Macbook Air is suffered from running laborious code, I save the animation on my Linux environment, 1024 bitrate, 1000 frames.

Numpy Slice Expression

 Suppossed we have two array a and b

 If we want to set b as finite difference result of a, we may tempted to do this

for i in range (9):
 b[i] = a[i+1]-a[i]

There's another (faster) way. The performance's close to the pure C, :)

b[:-1] = a[1:]-a[:-1]

What's that?

Numpy has slice form for array. If we have an array with length 10, the a[:] refers to all value in a.

a[1:] refers to a[1] to a[9] (without a[0])
a[3:] refers to a[3] to a[9]
a[:-1] refers to a[0] to a[8]
a[:-3] refers to a[0] to a[6]
a[1:-1] refers to a[1] to a[8]
...
and so on

Here's my tinkering with slice expression

>>> from numpy import *
>>> a = zeros(10)
>>> b = zeros(10)
>>> a[5]=1.
>>> a
array([ 0.,  0.,  0.,  0.,  0.,  1.,  0.,  0.,  0.,  0.])
>>> b
array([ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.])
>>> a[6]=2.
>>> a
array([ 0.,  0.,  0.,  0.,  0.,  1.,  2.,  0.,  0.,  0.])
>>> b[:-1]=a[:-1]-a[1:]
>>> b
array([ 0.,  0.,  0.,  0., -1., -1.,  2.,  0.,  0.,  0.])
>>> b[:-1]=a[:-1]+a[1:]
>>> b
array([ 0.,  0.,  0.,  0.,  1.,  3.,  2.,  0.,  0.,  0.])
>>>

 Sepertinya ada (banyak) yang mengartikan sebagai kendaraan bebas berjalan di manapun, bahkan di tempat yang saat normal gak bisa dimasuki, :(

Create CSV file using Delphi

 I used textfile variable to write to a file (or create it if it don't exist).

 CSV file? Just make sure that the name at assignfile  command had .csv extension, :)

 Of course we have to format the output to meet the CSV standart; separated by comma.

procedure TForm1.Button1Click(Sender: TObject);
var
    fileku:textfile;
    i,j,n:integer;
begin
  n:=10;
  assignfile(fileku,'data.csv');
  rewrite(fileku);
  writeln(fileku,'tadaa...');
  for i:=1 to n do begin
    for j:=1 to n do begin
      writeln(fileku,i,',',j,',','data',i,j);
    end;
  end;
  closefile(fileku);
end;

Delphi on OS X

 Here's the WineSkin version.

 I found it's way smoother than WineBottler version, ...., but hard to figure how to use it

 To install Delphi in OS X using WineSkin, we have to download and install Wineskin, of course, :)

• Open Wineskin Winery.app
• Make sure you have a Wrapper version and an Engine
• Select the Engine you want to use (I use WS9Wine1.7.52)
• Press the Create Wrapper button
• Enter in the name Delphi (or whatever you have in mind) for the wrapper and press OK
• When its done being created, click the button to view it in Finder in the finished window
• Close Wineskin Winery.app.
• Right click Delphi.app in Finder and select “Show Package Contents”
• Double click and run Wineskin.app.
• Now click on the Install Software button
• Select to choose a setup executable
• Navigate to the Delphi setup exe file you downloaded in step one
• Select the setup exe file and press the choose button
• At this point Delphi setup should begin, go through the Delphi setup like a normal install
• After the setup is done, back in Wineskin.app, it should pop up asking you to select the .exe file
• Choose the delphi32.exe file in the drop down list and press the Select Button
• Now press the Quit button to exit Wineskin.app
• Back in Finder, double click Delphi.app and start coding

 It has the same problem with WineBottler,  the toolbar tab's seem order by itself alphabetically, so the default toolbar tab is not ' standard ' tab but 'additional' one

code
unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
  jalan:boolean=false;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
  jalan := not jalan;
  if jalan = true then button1.Caption:='Stop'
    else button1.Caption:='Run';

end;

procedure TForm1.FormCreate(Sender: TObject);
begin
 button1.Caption:='Run';
end;

end.

.

Delphi on OS X

 I use WineBottler to install Delphi 7 on my El Capitan.

 It's installed, it can run.

 The one that tickle me is the toolbar list is scrambled, it's sorted alphabetically, so additional toolbar is in the first and act as default toolbar.

Obat Tidur Alami

 Jangan memandang layar di jam-jam tidur, baik layar TV, komputer, handphone.

 Misal terpaksa bekerja dengan komputer di malam hari, gunakan aplikasi seperti flux. Aplikasi ini menghilangkan warna biru di layar.

 Warna biru (seperti cahaya matahari pagi hari) membuat kita tetap terjaga, karena tubuh menganggap hari masih belum malam. Cahaya biru dari layar TV, laptop, hp membuat jam biologis kita menjadi kacau.

Heel and Toe?

 I tried several time to no avail. 

 It's just not working for me. 

 Maybe it's my drumming posture on throne, or other cause. 

 It's hard for me to lift my heel, so I use heel down technique all the time, :)

 Is it fast? 

 Not really, but  it's enough for my genre of music.

 If the fast heel and toe is needed, I manage to catch it up with normal kick with heel down and straight toe, and the second hit is with my toe in curl position (heel down)

 It isn't heel and toe technique, it's straight and curl toe technique, :D 

 

Yup...
