I can spark England very well.

Goodafternoooooooooooon!
Today, I dropped by this web page below.

http://news4vip.livedoor.biz/archives/51202593.html


,where there are so unique sentences, thou? i was not able to look at the sentences, such as the title of this post, without laughing. this is, we can probably say, 2channelic english. even now, u know, i can't write english politely, and can't produce english with uniqueness. so i hope i could handle english as funny as the sentences on the webpage, not only to straight express stuff.



P.S.
i wonder if i finish weekly homework...but, i believe it's ok because i got the proverb(?)...
...IT'S NOT TIME FOR PANIC YET, though i'm going to participate in camp tommorow. right?

International Intern

今日は、職場の先輩インターン生の実習最終日だそうで、約半年間の実習結果をまとめたプレゼンが行われました。一応、自分も一応同じインターン生ということで同席させていただきました。その先輩インターン生はフランスの方で、その人が通っている大学では半年以上のインターンシップを経験し、それを同大学で報告して初めて卒業なんだそうです。年齢については聞いていませんが、フランスに帰国後すぐに卒業ということなので多分一個上(?)かな。もしそうなら、日本・・・はもとより俺も結構危ないな。プレゼンで開発したソフトのデモを見る限り、革新的なソフトウェア…とはいかないまでも、少なくとも今の自分の技術力ではできないようなソフトウェアだったからなぁ。む〜、つまり、自分も一年後には、あのレベルの開発が出来なくてはいけないわけか.。しかも、少なくとも一つの外国語がペラペラの状態でw。

あ〜、頑張るのみ。

[思い出について]
--- sample 1 ---
I will never forget when I first met my best friend. I was new to school, and lost my way at a corridor, looking for my classroom. She asked me if I needed help. We started talking and found that we were in the same math class. After that, we have been best friends.

One of my unforgettable experiences was when I studied abroad in Spain for a year. I was stunned to find a world and a way of life that I had never seen before. Also, there are so many regions and cultures within Spain itself. I began to realize that there are ofdten more differences within a culture thatn between cultures. This seems like what I probably cound not learn, if I had not gone out.

一番忘れられない経験は映画のエキストラになってほしいと依頼を受けたときのことでした。撮影所が1週間うちのキャンパスで英が取りをしていて、図書館の前を行き来する人とカフェテリアで食事をする人を必要としていました。仕事その物は単純だったし、ちょっぴり退屈でさえあったのですが、監督や主人公の2里ともあうチャンスがあり、その点では本当に感激しました。

One of my undorgettable experiences was what I was asked to be an extra of the movie. The movie was producing at our campus for a week, so the persons who come or go out at the front of the library were needed. The work itself was easy and even bored for me, but I was really excited because I had an oppotunity to see the director of the filem and two main characters.


[Section two class 2]
I prefer to study with a group of students for the following reasons.

First, I can learn more by studying with a froup of students. For example, in 1995 when I was en eleventh grader in Kaisei High School, a provate high school in Tokyo, Japan, I often studied English with some of my claswsmates after school. One of them, Tanaka, was the best student in calss. Another one, Suzuki, lived in America for six years when he was in elementary school. They both knew a lot about English then, and they helped me a lot when we studied together. I knew a lot of kanji, Chinese-Japanese characters, and they learned them from me in turn. We learned a lot from each other as a group. If I had not studied with others, I would not have learned more about English. As the above example shows, I strongly believe that I can learn more by studying with a group of students.

When I turned twenty-one ( the legal drinking age in the U.S.), my friends took me out to a bar for the first time. We ate and drank and enjoyed ourselves late into the night. At the end of the evening, they presented me with a nice wine rack.

When I was in high school, I often baby sat for my neighbors' children. There was a girl whom I often used to look after. Her favorite book was "The Giving Tree." She would always refuse to go to bed unless I read the book to her at bedtime.

coffee junkey




ふと、毎日のcoffee摂取量が徐々に増えてきてることを実感。

とりあえず、ざっとネットで探って見たところ、コーヒーは飲みすぎても別に体には異常ないみたいみたい。ただ、流石に毎日ずっと飲んでると飽きるし、効用下がってくるし、なによりお金が・・・orz しかし、コーヒーでも使ってないと眠くなるしなぁ。気合で起きつづけようとしても集中力とか思考力が落ちるから効率はガタ落ちするし。ここは、もういっそのこと開き直ってcoffee junkieとしての道を歩むしかないのかw。By the way, 職場の隣のデスクの人がありえないスピードで設計とか実装してるの見るとビビります。効率落とさないで終日続くとかテラゴッドww。研究者仕様ですかそうですか(´・ω・`)

Input -> Output




[近況 part 3]

今日は、R&Dと大学で学んだ知識の関係性ついて。
今日、ようやく新技術の大まかな構造と相対的な位置づけを把握することが出来ました。また、その新技術に対して自分はどのようにアプローチをして、どの部分を開拓していくのか、その方針もある程度定まってきたように思います。新技術の研究を進めるに当たって、OSで学んだComputer Architectureを扱ったプログラミング知識や、Software Engineeringで学んだMeta Model, UML. OOPの知識や、Language Processorで学んだ構文解析, 正規表現の知識など、今まで学んできた様々な技術をフルに使っているという実感をひしひしと感じます。逆に言えば、これら技術のうちどれか一つでも欠けていれば、新技術の理解にさらに時間がかかってしまったのかな、とも感じます。もちろん、その他にも、学外活動で学んだtime schedulingとかnote takingの知識・経験もかなり役に立ってはいますが。Anyway、なんというか、今までの知識・経験を全て使って、頭をフルに回転させてる感覚がいいですね。中々やりがいを感じます。

さて、outputするために必要な知識は今日で大体inputし終えたんで、明日からは今までのヘタレっぷりを取り戻せるよう、ガンガンoutputしていきます。

では。

Ruby




昨日に続けて連続投稿です。ニチェ!
ー (誰も気にしていない)近況についてpart 2 ー

幸運にも、かねてからやろうと思っていたプログラミング言語、pythonとRubyのうち、Rubyを勉強する機会と巡り会いました!According to my rule of thumb, I will never study subjects, such as programming language, if I do not have an opportunity to use itなので、この機会をできる限り有効に活用して、Rubyを習得するよう心がけたいと思います。ただ、Rubyを習得することに傾注するあまり、TOEFLの勉強がおざなりになってしまっては本末転倒なので、そこら辺はうまくスケジューリングする必要はありますが。

しかし、今夏の活動力を前回の春休みにも発揮出来たらきっともっと成長したのになぁ、と思ふ今日この頃。む〜、今更そんなこと考えて後悔していても仕方ないんですが。でも、少なくとも、今の生き方の方が自分の性にはあってるのかな。Anyway, 動き出すのが遅かった自分が好き勝手に生きていくには、どうも越えなきゃいけない壁が多いみたいですな。

def say_goodnight(name)
result = "good night, " + name
return result
end

puts say_goodnight('everyone!")

では〜。

Cool Biz



インターンが始まって一週間が立ちました。軽い近況報告でも。僕のインターン先では、セキュリティ上の問題から残業があまり推奨されていないみたいで、インターン生の残業は厳禁だそうです。研修内容がR&Dだということが関係しているのかもしれませんが、実際、セキュリティ関係は結構きついです。嬉しいことは、残業が無いおかげで週末の予備校に向けた課題には、割と余裕を持って取り組めているってことですかね。

そうそう、僕が思うR&Dの最もよいところは、Cool Bizという名の私服出勤です。「あれ…? Cool・・・ Biz…?」的な服装が最高ですw。Googleでは、開発系社員の私服出勤を既に公言していますが、やはり研究開発系の職はスーツで出勤する必要性があまり無いみたいですね。いやぁホント、最高の環境ですw。一応僕はインターン生なんで、インターンシップ中にあまりでしゃばった真似をするつもりはありませんが、将来の職種の候補としてR&D系も良いかなぁと思いました。

おわり


P.S. 予備校もインターンシップも著作権やら秘密保持契約やらの関係で、あまり立ち入った内容がしゃべれないのがもどかしい今日この頃。

P.S.のP.S.
や…やっと覚えられた。。。orz
明日は満点取ってきてヤンぜ!

Lapses of Memory

しまった!?インターンの単位申請し忘れた!!インターン開始前に申請しないといけないのに、インターンは明日からという孔明の罠!!というかSoCとTOEFLばかりに気を取られてて、Traffic Theoryのレポートの存在も忘れてた!!ニコ○○動画なんて見てる場合じゃないって!


と、いうことで、今日は理工事務所に行き、なんとかギリギリで単位申請を受理してもらいました。ただし、受付の人曰く、単位申請するからにはインターン中の功績を評価する指導教員を選べ、とのこと。む〜、待てよ、これは・・・アリだな(ニヤリ)。研究室に配属してないから、指導教員は誰でも良いらしいので、これはもう行きたい研究室の教授を指名するしかあるまい。で、さっそく研究室に訪ねてみたところ、海外出張中で既に日本にはいないとなww。流石に教授ともなるとお盆なんて存在しないのかぁ、別次元級の忙しさだな。お盆は、今年度最大級のヒキコモリンリンと化して、寝る・食べる・パソコン・勉強以外何もやって無い僕とは別格ですね、わかります。あ、メタボ解消のため、GYMにはちょっと行ってましたが。

と、そんなこんなでインターン関係は何とか一時的に片がついて、現在はTraffic Theoryのレポートを鋭意制作中。ってblog投稿してる場合じゃなくね!?

Strategy, SoC memo C1(1)




Basic TOEFLが昨日ようやく終わりました。途中から何人かUSAに帰ったので、結果、最終日の受講生の状況がハーレム状態だったのが唯一の良い思い出です。一方で、まわりの受講生が全員高校生とはいえ、皆帰国子女だったので、readingの早さとかlisteningの把握力とか負けまくりだったのはつらい思い出 orz。ま、最後のテストではぼちぼちいい点数取れたので、よしということで。

今回、さらっとTOEFL iBTの概要を学んだだけだけど、やっぱstrategyは大事だね。readingとか、ITPの問題だったけど、普通に正答率2倍になったわ。Listeningも同じく、とりあえず正答率が5割を越えた。ただ、iBTのstrategyは本当にさらっとやっただけで、まだ勉強していないところもいっぱいあるらしい。実際、今までやってたのはR/Lだけだしね。

と、そんなこんなで、明日からはiBTのR/L standardとBasic Writingの授業開始です。今まで最年長だったけど、今度は社会人クラスなので最年少になるらしい。といっても特に変わらないと思うけど(帰国子女がいなくなる分、全体的にはレベルダウンするのかな)。まぁ、とにかく、ぼちぼち頑張ります。



----- SoC C1 (1) NOTE(途中) -----
レポート課題:C1章(2)No1 演習1,2 PP.69

1. プロセスモデルのOSとスレッドモデルのOSの特徴を説明せよ。
2. 4種類のOSの動作モデルと特徴を述べよ。




----- noteのまとめ -----
[C1章 組み込みソフトウェアの基礎(1)]
概要:組み込みシステムの特徴、ハードウェアの基礎知識、組み込みシステムとは何か、車を用いた事例

・Introduction
一般的にコンピュータ関連産業をIT産業と呼ばれているが、経済産業省では明確にIT産業とET産業に区別している。

IT:Information Technology
-> インターネット系情報サービス
Ex. 銀行のオンラインシステム、座席予約システム

ET: Embedded Technology
-> ある目的に専用化されたシステム。具体的には、汎用コンピュータ以外のコンピュータシステム。
Ex. i-Pod, 家電, 携帯(ただし,iアプリは汎用コンピュータ)

注:ロードして実行するプログラムは、組み込みソフトウェアではない!
Ex. java program, PDA
→このようなソフトウェアは、アプリケーションソフトウェアという方が適している。

しかし、言葉は生きているので、現在の定義がこの先も常に変わらないとは限らない。
→定義として覚えるのではなくイメージとして覚えた方が効率的。


・ET産業と特徴
- 厳しいリソースの制約
- 高い信頼性
→PCとは違った信頼性
cf. 回収経路が違う。
つまり、組み込みシステムに対するユーザの期待度が高い。
cf. windows XPがフリーズしても、ユーザには暗黙の諦めがある。
cf. i-Podがフリーズしたら、ユーザはクレームをつける。

・原因は何か?
ユーザはモノを使うとき、思い描いた動作するためにはどのように操作すればいいのか、という予測を行いモノを扱う。
この予測が期待値を左右する。よって、
-ET系は期待値が高い。
-PCに対しての諦め。
という差異が起こる。

Ex:リアルタイム性
→ある操作に対して、その操作が完了するまでどの程度時間がかかるか、という予測。
開発者は、この予測を正確に把握する必要がある。ただし、早ければよいということではない!


・では、組み込みシステムにはどのような厳しい要求があるのか?
1. 重大な欠陥にたいする賠償→めちゃくちゃ損害が大きい
Ex: Panasonicが10年前に行った欠陥ストーブの回収

2. 開発サイクルの短縮
6ヶ月未満が4割、1年〜6ヶ月が4割。
→8割の組み込みシステムは、1年未満のサイクルで製造されている。
→技術者はドMなので、やりがいを感じる(?)→デスマーチ(?)

大抵は、半期モデルとかで、6ヶ月単位でサイクルすることが大きい。
というか、実際にはこれ以上生産サイクルは縮まらない。しかし、ソフトウェアのソースコードの行数は年々増加している。
→そろそろ限界に達するので、何かしらの現象が起こる(?)

Q. 技術者に余裕をもたらすために、生産サイクルの単位をもっとゆとりを持たせられないのか?
A. ユーザがそれを求める限り、企業倫理的に無理。

結論:このような状況下で開発を成功させるのは無謀。実際にほとんどのプロジェクトが"成功"といえる水準に至っていない。
仮対策:以下に効率的なエンジニアリング手法を取り入れるかが重要。
ex. 過去の資産を活用、開発工程の管理




・組み込みソフトウェアの、HW的な違い
1. Sencorがある
2. Actuatorがある
3. I/Oが違う

Sencor:温度、変位、音、磁気、化学量、光度などに反応して電気信号に変換する素子
Actuator:センサの逆。電気信号を物理的、科学的変化に変換。
Ex:電磁ソレノイド、motor

・具体的な制御例(Case:直流Motor)
電力up→pulse幅down→早く回転する
電力down→pulse幅up→遅く回転する

motorだけとっても、制御の仕方は他にも、AC(Alternating Current)・stepping・sorvo・linerなどがある。

・他HW知識
Analog量とDegital量, Sampling Freq, AD transformation
→全部実験でやった奴。

・data圧縮
1. 可逆圧縮
→ZIP,LZH, GIF, PNG

2. 不可逆圧縮(圧縮率高い)
→MPEG, JPEG, AAC
→このため、動画では圧縮をする度に品質は落ちていく。(が、人間が感知できるほど気になる量ではないらしい。)

圧縮例:
1. Run Length

事例:動画圧縮
背景はあまり変わらないことが多いので、差分データのみ(動くモノのみ)を変化させるようにすれば、割と効率的に動く。
逆に言えば、桜が落ちるシーンや、潮の満ち引きがある海では、背景が頻繁に変わるので、あまり効果は期待できない。



・組み込みシステムで扱うOS(基本的にCAやOS、programing Cで勉強したこと)
内容:MPU内部における割り込みの動作、外部割り込みと内部割り込み、Big EndianとLittle Endian、←の性能比較、
MPUとデバイスとデバイスとでEndianが異なる場合の配線、キャッシュ(の動作)、周辺デバイス、レジスタ、RTOSを動作させるために必要なI/Oデバイス

(以下、上述の内容のうち、自分が知らなかったところだけを補足)
- NMI(Non Mashable Interrupt):停電等が起こってもいつでも割り込みで切るような仕組み
- BigEndian: 上位バイトから出力
- LittleEndian: 下位バイトから出力
→読み込みの時はBig Endianの方がよい。
- ではなぜLittle Endianが主流なのか?
→Little Endianは当初、計算機気のためではなく、電卓のために設計されたから。
→このため、現代でもその名残りとしてLittle Endian方式が主流となってしまった。

・BEとLEの利点
LE:数値の桁数が分からなくても解析できる
BE:メモリの内容が直感的にわかる。(人間の文字を読む順序と同じ)
→デバック時や、memory dumpで内容を把握するときに便利。
→LEの場合は、変換関数を通した後でレジスタの内容を出力する必要がある。

・なぜBEが良いと言われているのか?
→自然界のあらゆる現象は、すべてBig Endianと同じだから。
またLEの場合、ハードでバイトスワップしなくてはいけない。
→つまり、Busごとをごっそりswapする。

このような考えは、通常、IT産業では扱わない。

・キャッシュ
- write through: 書き込み時に、キャッシュメモリと実際のメモリに対して書き込みを行う
- write back: 書き込み時に、キャッシュメモリだけを書き換えて、実際のメモリに対しては書き込みを行わない(メモリはちょっと遠い位置にあるので)
使用例:ある程度write backでメモリを無視おき、write throughで今までの内容を一気に書き込む。
demerit:メモリに書くべき内容がかかれない危険性がある。

キャッシュは、当たれば早いが外れると極端に遅くなる。
→99.999%時間内に動作しても0.0001%間に合わない、では許されない。
→組み込みシステムでは、キャッシュを入れることにより、逆に遅くなることも有り得る。

Basic TOEFL iBT




現役高校生と共に勉強しながらはや2日。噂では、課題の量がそこそこあるとは聞いていたが、正直そこまでではない。なんせ一日で終わるぐらいだからね。来週からは始まるstandard classでは、課題量が大体1.5倍ぐらいになるらしいけど、それでも1 class/weekなら無問題レベルじゃねwwwww





と、思ってた時期が僕にもありましたorz
そういえば、writing classも同時平行で取っていたな、と。writingの課題は比較的多いとか言ってたから、まぁとりあえずstandard classよりは多いはず。インターンで平日は夕方からしか勉強できないことを考慮すると、大体毎週の課題を終わらせるのに3日ぐらいかかるのかな、多分。

機密保持やらなんやらの関係で、インターン先からのお持ち帰りの課題が来るとは考えられないけど、もし課題が来るようなら、廃人決定かw。しかも、当初の予定では、このスケジュールに加えてFAT32も構築しようとか思ってたからなぁ、死亡フラグは事前に折っといて正解だったな。

む〜、とはいえ、目標は課題をこなすことではなくて80点を取ることなわけで…、どうせ暇な時間が出来たとしても勉強することには変わらんか。

Passage: Geology




昨日、ESSのキャンプから帰ってきて、さっそく今日から予備校生活がスタート。

いやぁ、高校受験の頃を彷彿させる授業だね。懐かしい!
基礎英語は、はっきりいって訛ってるし、自分以外全員teenagerとかいう環境だけど(ある意味恵まれたのかw?)、まぁそれは高校で英語サボってたツケだと思って、ガリガリ頑張っていくしかない。羞恥心は高校においてきたから、もう失うものもないしね。

と、いうわけで、次はword listとlisteningとstructure!

P.S. 明日必着の履歴書がまだ郵送されていない件
いや、まだ慌てるような時間じゃない!きっと、超特急便ならなんとかしてくれる!


※Titleは今回勉強した内容で、それをblogに載せようと思ったんだけど、よくよく受講のしおりを見てみると著作権侵g(ry

Block cource: SoC Design




Until today, I took block class which lasts three consecutive days from the next day of final test held. Definitely, it was difficult for me to listen to class from 10:40 to 19:30, because, you know, too long! But with my stress, I have listened to teacher saying at the place called "frontier", however, I was not able to study at there without 2 liter pet bottle per day. I know some engineers taught to us with good presentation, but others...orz Anyway, I would not like to hear "SoC" no more!


By the way, I have finished final mini-research report, so I finally get my own time! So, I will leave for Fukushima Pref. in 6 hours, for participating in the ESS camp as a vacancy! Maybe, I have at least several assignments more, but... I do not care anymore! I will think about it after return.
