First of all, go to System Preferences, then lick on the Language & Text icon. Click on “Chinese – Simplified” flag, and select “Pinyin – Simplified”.

Then you can select “Pinyin – Simplified” as you input language by hitting “Command + Space”. Just hit “Command + Space” until “Pinyin – Simplified” is selected.

Now you can type pinyin and see the corresponding characters popup. You can choose one of the characters by either typing space or the corresponding number. For exsample, let’s type this following pinyin. You’ll see the corresponding Simplified Chinese characters. That’s it!

1) One Button Suits:
One button suits are the easiest to remember. The button should always be buttoned when standing and unfastened when one sits down.

2) Two Button Suits:
Two button suits are also simple. The top button should remain buttoned, while the bottom button is left undone.

3) Three Button Suits:
With three buttons, you have options. You can either button the top two and leave the bottom unfastened, or simply button the center button.

April. It is the season when new employees who wrap the body in a new suit overflow in the town. I often see that a young man buttons all buttons on single breasted suit without knowing the basic suit manners. Each time, I feel like teaching him how to button suit buttons. Yes I was like the young man when I was a new employee. On the other hand, it is every once in a while but there is a time when I see a man old enough to know the basic buttons all the buttons of single brested suits. I will not say anything about it.

The virtual machine could not be started because the hypervisor is not running. The following actions may help you resolve the problem:
1) Verify that the processor of the physical computer has a supported version of hardware-assisted virtualization.
2) Verify that hardware-assisted virtualization and hardware-assisted data execution protection are enabled in the BIOS of the physical computer. (If you edit the BIOS to enable either setting, you must turn off the power to the physical computer and then turn it back on. Restarting the physical computer is not sufficient.)
3) If you have made changes to the Boot Configuration Data store, review these changes to ensure that the hypervisor is configured to launch automatically.

In the case of Dell Precision T5400,  the following 3 BIOS settings change need to be done:

• Security – Execute Disable: On
• Performance – Virtualization: On
• Performance – VT for Direct I/O Access: On

After the BIOS setup made, just choose “Save & Exit” in order to reflect the changes. Then try it again. you will be able to connect & start your Hyper-V Virtual Machine. Enjoy Hyper-V!

What’s GNUstep?

Probably you may know Apple’s Cocoa , Objective-C developmet frameworks(was known as NeXTSTEP many years ago). GNUstep is a GNU clone which not only is compatible with the Cocoa but also supports cross platform!

GNUstep provides a robust implementation of the AppKit and Foundation libraries as well as the development tools available on Cocoa, including Gorm (the InterfaceBuilder) and ProjectCenter (ProjectBuilder/Xcode). GNUstep currently supports Unix (GNU/Linux and GNU/HURD, Solaris, NetBSD, OpenBSD, FreeBSD, Darwin) and Windows. — GNUstep Overview –

Installing GNUstep on debian

First of all install the following 2 debian packages which are very fundamental for GNUstep development. The version of debian on which I tried it is 5.0.4.

- gnustep – The GNUstep Development Environment — user applications
- gnustep-devel – The GNUstep Development Environment — development tools

If you are not debian user, find out GNUstep packages for the platforms you use from here.

Compiling Objective-C code with GNUstep

main.m

I coded a simple program above that captalize a string “how do you like wednesday?”. Now I want to compile it. But before that, make sure that gcc (>4.6) is installed on your platform. If not installed, just install it.

1. Compiling by executing gcc command line

gnustep-config is a usuful command that provides information on the current gnustep installation. gnustep-config’s –objc-flags option prints all the flags required to compile an ObjC file, and –objc-libs option prints all the flags required to link a GUI ObjC program.

2. Compiling by Makefile, a little more sophisticated way

As a different way, you can create a Makefile for the program to compile. I created the following Makefile using examples from “A GNUstep Programming Tutorial”

GNUmakefile

After you compile it with either way, finally you can execute the compiled program. Its output will be like this:

Enjoy Objective-C programming with GNUStep!

1. SCP Compress Option

SCP‘s -C option enables on-the-fly compression. Transfering an achive.log(/var/tmp/archive.log) using scp with compress option from a remote server to local:

2. On-the-fly compression using SSH and TAR

Compressing ‘archive.log’ with tar, sending its output to STDOUT, and then piping it from remote server to STDIN of local:

Speed Comparison

I tested them with and without on-the-fly compression and measured their real time. I transferred a large size file, archive.log which takes up about 1.1G disk usage from a remote server named “sakura” to local machine.

Do compress and make the most of your CPU power, then you can finish it In a shorter period of time!

So like other Windows 8 enthusiasts I gave it a try – installing it in VMWare fusion4 on my Macbook (I installed Windows8 Developer Preview Build in my Macbook as well when it came out last year). To be honest, it is not so excited only to install it on standard laptop PC. Let’s wait for the one installed on some touchscreen computer to come out.

[Watch Out] For this time of Consumer Preview Build, it’s not available on tablets. The preview of Windows 8 will only work on PCs and laptops based on standard Intel Corp x86 chips.

My environments

• Host OS: Mac OS X Lion
• H/W: 2.7GHz Dual Core, 8GB MEM, 500GB SATA@ 5400 rpm
• Resource Assigned to VM (VMWare Fusion4): 1GB Mem, Max 60GB

What I got for the installation

• ISO for Windows 8 CP
• Product Key ( listed on the Windows 8 ISO download page)

Good Will Hunting – “Idiosyncrasies”

Will: Yeah, I went on a date last week.
Sean: How’d it go?
Will: It was good.
Sean: Going out again?
Will: I don’t know.
Sean: Why not?
Will: Haven’t called her.
Sean: Christ, you’re an amateur.
Will: I know what I’m doing.
Sean: Yeah.
Will: Yeah. Don’t worry about me. I know what I’m doin’. Yeah, but this girl is like, you know, beautiful. She’s smart. She’s funny. She’s different from most of the other girls I’ve been with.
Sean: So, call her up, Romeo.
Will: Why? So I can realize she’s not that smart, that she’s fuckin’ boring? Y’know–I mean…this girl is like fuckin’ perfect right now, I don’t wanna ruin that.
Sean: Maybe you’re perfect right now. Maybe you don’t want to ruin that. I think that’s a super philosophy, Will. That way you can go through your entire life without ever having to really know anybody. My wife used to fart when she was nervous. She had all sorts of wonderful idiosyncrasies. You know what? She used to fart in her sleep. Sorry I shared that with you. One night it was so loud it woke the dog up. She woke up and gone like “oh was that you?” I’d say yeah…I didn’t have the heart to tell her…Oh God…
多分、お前も今完璧で、そんな完璧な自分を壊したくないんだろ？それは素晴らしい哲学だ。そんな風に一生誰かを本気で知ることなく過ごすんだろうね。オレの妻は緊張するとたまにオナラをするんだけど、彼女にはそういった面白い癖がたくさんあった。ちょっと変な話なんだけどね、彼女は眠っている時もオナラをするんだけど、ある晩とても音が大きなオナラをして犬が目を覚ましたんだ。そして彼女自身も目も覚まして”今のはあたなでしょ？”って言ったんだ。当時本当のことを彼女に言う勇気はなかったよ。

Will: She woke herself up?
彼女は自分の音で目を覚ましたの？

Sean: Yesssss. Oh Christ….aahhh, but, Will, she’s been dead two years and that’s the shit I remember. Wonderful stuff, you know, little things like that. Ah, but, those are the things I miss the most. The little idiosyncrasies that only I knew about. That’s what made her my wife. Oh, and she had the goods on me, too, she knew all my little peccadillos. People call these things imperfections, but they’re not, aw, that’s the good stuff. And then we get to choose who we let in to our weird little worlds. You’re not perfect, sport. And let me save you the suspense. This girl you met, she isn’t perfect either. But the question is: whether or not you’re perfect for each other. That’s the whole deal. That’s what intimacy is all about. Now you can know everything in the world, sport, but the only way you’re findin’ out that one is by givin’ it a shot. You certainly won’t learn from an old fucker like me. Even if I did know, I wouldn’t tell a piss ant like you.
そう。彼女が死んで2年になるけど、そんな変なこともあったね。いい思い出だ。そんな小さな一つ一つのことが最も懐かしい。自分だけが知っている小さな癖、それがあるから彼女はオレにとって特別な存在（妻）なんだ。彼女もオレの癖をすべて知っている。それを欠点と呼ぶ人もいるけどむしろ逆だ。そうやってお互いを知っていくんだ。お前は完璧じゃない。お前が会ったその彼女だって完璧じゃない。でも問題はお前達二人がお互いにとって完璧であるかどうかなんだ。それが二人の関係にとって最も重要なことなんだ。でも、それは自分でそこに飛び込んでみない限り分からないだろう。もちろん、オレのよな愚かな老いぼれから学ぶことはできないし、知っていてもお前には教えない。

Will: Why not? You told me every other fuckin’ thing. Jesus Christ. You talk more than any shrink I ever met.
Sean: I teach this shit, I didn’t say I knew how to do it.
Will: Yeah……you ever think about gettin’ remarried?
Sean: My wife’s dead.
Will: Hence, the word remarried.
Sean: My wife’s dead.
Will: Yeah.. Well, I think that’s a super philosophy, Sean. I mean that way you could actually go through the rest of your life without ever really knowing anybody.
Sean: Time’s up.

This below is how I setup Internet connection sharing with my MacBook and How I resolved the issue.

Sharing Emobile Connection to Computers Using Wi-Fi

Assuming that your Macbook is connected to the Internet using a Emobile modem.

1. Open System Preferences > Click Sharing

2. Select Internet Sharing (However don’t turn on Internet Sharing Yet, otherwise you won’t be able to edit Wi-Fi Option)

3. Choose “Share your connection from” and “To computers using” like this:

• Share your connection from: Emobile Modem (ex. HUAWEIMobile-Modem)
• To computers using: Wi-Fi

4. Click Wi-Fi Options and configure an internet-sharing network. Here is my configurations:

• Network Name: mbp-shared-wifi
• Channel: 11 (default)
• Security: 128-bit WEP

5. Turn on Internet Sharing

That is all need to be done for internet sharing. You should be able to join the shared network “mbp-shared-wifi” if the channel( more specifically one of 11 802.11 channels) that you chose is not interfered by any sources of signals near the network.

Finding Out The Right Wi-Fi Channel

The purpose here is to find out the right channel for the internet sharing, the one which is least occupied.

Airport Command included in Mac OS X

airport is a built-in command line tool that enables you to manage 802.11 interfaces and to get all sort of information for 802.11 interface.

First, the tool is not located at one of paths which are included in $PATH, so let’s create a symlink to the tool like this:

A command line “airport -s” performs a wireless broadcast scan and gives you a list of Wi-Fi networks nearby. It reports information about SSID, BSSID, RSSI, channel, authentication, and so on.

Now you want to know which channel is used least from the output of “airport -s”. This command line below gives you numbers of how many of access points(SSIDS) use each channel.

From the result above, it would be good to choose channel 8, 3, or 10. I chose channel 3 this case. I setup the internet sharing again with the channel 3, and confirmed that I was able to to join the shared network “mbp-shared-wifi”.

Also pay attention to RSSI

You may want to pay attention to RSSI. According to wikipedia, RSSI is the relative received signal strength in a wireless environment, in arbitrary units. RSSI is an indication of the power level being received by the antenna. Therefore, the higher the RSSI number (or less negative in some devices), the stronger the signal.

Simply, the channel with lower value of RSSI is less likely to cause interference than the one with higher value of RSSI. It would be good to choose the channel with least value of RSSI for the internet sharing.

Web Based Tool – Wifi Stumbler

There is a local wifi scanning web service, called “Wifi Stumbler“. This service provides you the information to choose the best wireless channel to choose. A good thing about this is that this is free web serivce, you don’t need airport command or any kind of wifi scanning software to install on your computer. See the site for more detail. Here is the scanned output of my wifi environment by Wifi Stumbler.

I believe this is probably one of the most famous Japanese poems. All Japanese who completed compulsory education must have learnt it in school, and might like and still remember it mostly.

Today I found kizuna311, a website that launched by a Hollywood Actor Ken Watanabe to encourage Japan Earthquake/Tsunami Victims(see also Ken Watanabe launches website to encourage solidarity in earthquake aftermath). In kizuna311, he read this poem, “Ame ni Mo Makezu”. Here is its youtube video. A transliteration and English translation for the text of the poem follow:

※ Source: Wikipedia Ame ni Mo Makezu

I actually saw the poem after a long interval. It was exactly the same “Ame ni Mo Makezu” as before. But this time I felt something different, something that I haven’t felt before. I read this poem more empathetically than never before. This is absolutely because of what we Japanese have experienced for last few days – Japan earthquake and tsunami. You will see in this poem the author’s ideas about how he should think of nature, how he should live, how he should support people, and whom he wants to be like. It must teach us a lot especially for this time of devastation and suffering, and let us start thinking of what we can do for the victims.
