日記を再開。今日は一人で過ごせたので、ファミレスにこもって開発環境を整え、串カツ田中で晩酌をして、そして久々に日記用のリポジトリを開いた。

書いていない間に色々とあった。少しずつ補完していこう。

大きな出来事は、転職したことだ。たしか6月頃にやめて、9月に入社した。

といっても業界を変えた前回と比べれば、今回変わったのは扱うプロダクトとプログラミング言語だけで、自身の貢献すべき点は変わらない。育休前と同じように好き勝手に働いて、そして楽しく過ごしている。

辞めた会社については、本当にタイミングが残念だった。子育てしながら働きたい私とプライベートなんて気にしてられない会社のミスマッチは大きかった。これまでならそれを改善しながらタフに過ごしていただろうが、子どもができるとすっかり守りに入る。

ちょうどこの前先輩と飲む機会があったが、いまは多少なりとも落ち着いているらしい。ワークライフバランスはともかく、優秀な人材は多くいたので、このまま頑張ってほしいなと思う。

なんで日記を書こうかと思ったかというと、出来事をメモしておくほかに、会社のtimesには書くのがためらわれることがあったからだ。

それはBUMP OF CHICKENのことで、先週からずっと**『THE LIVING DEAD』**を聴いている。正確には各曲のタイトルばかり見ている。30代には伝わるかなー。コピペでなく、キーパンチで全曲打ち込んでみる。

  • Opening
  • グングニル
  • ベストピクチャー
  • 続・くだらない唄
  • ランプ
  • K
  • リリィ
  • Ever lasting lie
  • グロリアスレボリューション
  • Ending

読んでいるだけで赤面している人は、きっと同世代だと思う。「ベストピクチャー」なんて、もう絶対にこの世には生まれてこないワードだし、「・くだらない」も天才的だし、、ここまでくると地味に「ランプ」もヤバい。

そしてこれを「Opening」と「Ending」で挟んでいることで、このアルバムは金字塔となった。椎名林檎のアルバムの「タイトルのフォーマットにルールがある」もそれなりにダサいけれど、そんなのを遥かにブッちぎって『THE LIVING DEAD』はダサい。「ベストピクチャー」1曲で、そのへんのダサいアルバムは皆殺しだ。

そして個人史として重要なのは、このセンスが私の中に血肉として入っていることだ。どれも突き放すことはできず、親戚の家でくつろぐような関係性があるのだ。日記を書きながら思い出したが、私が初期に作ったMIDI曲のひとつに「マインドソルジャー」という曲があることを思い出した(死)。


<Week8>

2021/02/21

I bought “Introduction to Rust Language” and had been studying it. As for pronunciation, I could pronounce “edge voice” and felt my throat was relaxed a little.

From Thursday, I went back to home with my baby. I had not study anything in home.

Sun, Feb 14, 2021

It’s a beautiful day today. I took my baby to the park and we relaxed on the grass.

Yesterday I tried to implement a API client with Rust. I successed to sending GET and get json data. But now, I can’t convert with using Generics.

And today, I’ve learned it and my program progressed.

Mon, Feb 15, 2021

It was rainy. We had an earthquake two days ago, and Fukushima was damaged much. This rain might cause a second disaster.

I tried to handle Rust in a cloud server. So, I have to end up learning AWS. And I want to learn Rust more, so I will buy the Japanese books about Rust and AWS.

As for voice training. I learned “Edge voide.” I couldn’t do it when I watched the youtube video about it. Before I learned “lip roll” too. I will try to make those my daily routine.

Tue, Feb 16, 2021

I was surprised my baby could open sliding doors by himself these days.

Vocal lesson trial - I refered yesterday - was not held because the teacher forgotten it! She explained her child got sick and it caught her all attention.

I dictated the following video.


This week’s idiom sounds painful, not so smart. But, What does it mean in the conversation? Let’s listen.

How did your job interview go yesterday?

I really shot myself in the foot.

Oh, No. What was happened?

I couldn’t size my old both would turn to be a interviewer’s mother.

Oh, You know you might get the jobs, right?

To “shoot yourself in the foot” means, to do something foolish that causes harm to yourself.

You don’t mean to, of course, but it happens anyway.

How did the job interview go yesterday?

I really shot myself in the foot.

Oh, No. What happened?

I criticized my old ** boss who turned out** to be the interviewer’s mother.

Um, You know you’re not getting that job, right?

To “shoot yourself in the foot” means, to do something foolish that causes harm to yourself.

You don’t mean to, of course, but it happens anyway.

Wed, Feb 17, 2021

I have been reading the book “Introducing to Rust language” since yesterday. Now, I have read it until Chapter 2. I will study the essential function tomorrow.

And I can pronounce the “edge voice” today. This year, I figured out that I’m not good at breathing. So, I will try to improve how to breathe.


<Week7>

2021/02/14

I finished practicing Rust with Exercise.

And this Monday was Superbowl. I was suprised the Chiefs couldn’t get any touchdowns. But you might be sure that Mahomes is the best quarterback as you watched his throw.

Sun, Feb 7, 2021

I played the video game “Valkyria Chronicles” all day.

Mon, Feb 8, 2021

I watched Superbowl. It was fun, but I couldn’t enjoy so much because Packers was not there.

Tue, Feb 9, 2021

These days, I didn’t take any lessons. That’t why I couldn’t talk so well in today’s lesson.

Learning is the same as mustle training. If you don’t do, your knowledge or mustle leave.

Wed, Feb 10, 2021

Today’s lesson was good. Tought I haven’t reviewed this lesson’s video, my pronunciation when I’m talking with someone was better than before.

And I applied to a trial of the vocal lesson. Because I found out I got better if I knew how to use my throat.

Thu, Feb 11, 2021

Rust practice, I’ve been learning it since a month ago, is going to end. I’m able to implement this smart language. However I can’t occasionally understand why it works and don’t know some useful functions.

I listened to “If I Ain’t Got You” by Alicia Keys. When I have listened to this for the first time was about 15 years old. Then, this song’s rhythm and vocal touched me. However, I couldn’t understand the meaning of this lyric. But I understood it now, and it moved me again.

Fri, Feb 12, 2021

I finished Rust tasks given by Exercise. I learned how to implement so I’m going to create some simple apps.


I dictated the following video.

Some people talk a lot, others not so much.
But, how can talking have the price? Jonathan. This weekend, I’m going to organize my workspace. It’s going to clean and organize.
You’ve been talking for a month.
It takes time.
Anna, talk is cheap. Just clean your office.
It’s easy to say you’re going to do something. It’s a lot harder to actually do it.
This is what “talk is cheap” means.
Another expression that means the same thing is “Action speak louder than words.”

Almost perfect!


Sat, Feb 13, 2021

Today, I joined a Clubhouse’s room for the first time. The theme of that room is to practice English. I not only used Clubhouse for the first time but also talked with unknown people. That’s why I got nurvous and feeled stiff in my mouth.

After that, I practiced a pronunciation of “th.” “th” is one of the most difficult pronunciation in all consonat.


<Week6>

2021/02/07

I found the way to relax my throat this week.

Sun, Jan 31, 2021

My wife went out in the afternoon, so I took my baby for a walk. There were more people in the park than usual because of holiday. It was a nice weather.

Mon, Feb 1, 2021

January has already gone. I feel time pasts fast.

My family took a walk, and my baby boy sat on the grasses for the first time. He pulled the grass and tried to bring it to his mouth.

Today’s lesson was so fun, but I couldn’t understand my tutor so well because I didn’t know the words she used. I think they were not so difficult. I have to remember them.


ひさびさに日本語に切り替え。英語の発音について色々と改善をこころみた結果、身体とくに喉の脱力が自身のテーマになると感じた。

下記の動画を見ながら、喉を開く感覚を試してみる。

Tue, Feb 2, 2021

I couldn’t take today’s lesson because I made a mistake the time when it started. Students can’t send a message to teachers, so I didn’t have a chance to say sorry to her.


I tried to dictate the following VOA video.

I dictated as below.

Some people are strong will and opinioned. Other is maybe this.
Jonathan. How did your zoom date with my cousin flow a week ago?
I thought it was great. But, when I asked to she wants to talk again next week, she was kind of wishy-washy.
What did she say?
She talks about how busy she was going to be.
Yeah, that’s a NO.
Someone who is “Wishy-Washy” doesn’t show strong ideas or beleives about something.
They don’t give clear answers, and they may go back a force about dicision.
“Wishy-Washy” is not exactly a good way to be described.

And it’s correct sentences.

Some people are strong-willed and opinionated. Others may be this.
Jonathan. How did your zoom date with my cousin Frederika go?
I thought it went great. But, when I asked if she wanted to talk again next week, she was kind of wishy-washy.
What did she say?
She talked about how busy she was going to be.
Yeah, that’s a NO.
Someone who is “Wishy-Washy” doesn’t show strong ideas or beleifs about something.
They don’t give clear answers, and they may go back and force about a dicision.
“Wishy-Washy” is not exactly a good way to be described.

I especially couldn’t understand “ask if she wanted.” I didn’t have the phrase “ask if.”

Wed, Feb 3, 2021

I focused to practice Rust too much, so I went to bed lately than usual.

Tur, Feb 4, 2021

An hour after my baby had a breakfast, he got allergic to eggs. So I took him to the hospital. The doctor said his allergy is not so terrible, which made me releived.

Sat, Feb 6, 2021

I tried a Rust task, “Wordy.” And I figured out how try_fold worked.


As usual, I have been studying English and Rust.

I realized My English skills got better these days. I can tell them my thinking or feeling though it takes time.

Next goal are belows.

  1. Being able to listen to the tutor’s English completely
  2. Having more phrases I can speak immediatery
  3. Speaking fluently little by little

And this week, the Packers was defeat by the Buccaneers. It might be the worst disaster in this year. I was going to write the review of this game, but I’ve not written it yet.

Sun, Jan 24, 2021

I learned concurrency today, too. I’ve submited my solution, but my solution with multi-threads didn’t get so faster, rather slower than single-thread. I will have to re-implement next week.

Tomorrow is the Conference Championship. I’m getting a little nervous. If Packers beat Buccaneers tomorrow, they get to the first superbowl in ten years, when I watched NFL and became a Cheese-head for the first time. It will be held at 5 AM, so I must go to bed earlier today.

Mon, Jan 25, 2021

I’m so depressed. I learned ”gutted” because Aaron Rodgers said “gutted” in an online interview after the game.

I guessed The Packers took momentum in the second half. But they couldn’t turn the game around. Besides, after 2-minutes-warning, Kevin King was called Pass Interference. I guessed that refereeing was not good. I mean, “It was a good call, but it was a bad rule.”

Thu, Jan 26, 2021

___ ___ ___ brushing his teeth any second.

I’ve answered many questions in Hinative today. I explain it in English so that I can learn English too. It’s a win-win relationship.


“I can change myself, but I cannot make anyone change.” It’s my policy. When I hoped someone to change and ask him or her that, it never got a good result.

Moreover, I figured out it is not very respectful because people can decide their own actions. I don’t have the right to make someone change, so I try to focus on what I can control.


Today’s lesson.

  • catch my attention
  • lose focus

Wed, Jan 27, 2021

Today’s online lesson was so good. I realized I could do an easy discussion, though I couldn’t understand a little what my tutor said.

The next goal is to speak what I’m thinking fluently. Now, I speak English with pausing sometimes.

Tur, Jan 28, 2021

It was too cold to take my baby for a walk today. In the evening, it got snow for the first time in this season. If it snows tomorrow, I’m going to get him to watch it. He has never seen snows in his 9 months life.

Below is the words I learned in today’s lesson.

  • bothersome
  • conscious effort
  • material

I learned Rust a lot today. I got a breakthrough about concurrency and macro. If I get knowing more about Lifecycle and Reference, I get used to Rust.

Fri, Jan 29, 2021

It was sunny and warmer than yesterday. I took my baby for a walk. He was loved by a convenience store clerk and the woman lining in front of me in the UNIQLO. He had winsome.

I had my wife take care of him in the afternoon. I thought about going to prepare “The beginning phrases when I speak,” such as “That sounds …”, “I’d say …”, and so on. I made a little, and then I tried them in today’s lesson.

In the evening, I bought some appetizers to go in the bar-restaurant I was interested in but had never been to (because of COVID-19). They were a bit expensive but so tasty.

Sat, Jan 30, 2021

My wife took care of our baby in the afternoon, so I solved some Rust practices.

After I took him to bed, I practiced English pronunciation, especially “flap-T,” such as “water,” “better,” “out of,” and so on. ELSA, the English pronunciation training application, told me my flap-T pronunciation is not correct. But I thought it was decent.


I studied English and Rust this week.

To practice with ELSA and to write and record a daily diary are getting my night routine. I want to continue for a year.

As for Rust, I learned concurrency(multi-threads) this week, but I couldn’t use it efficiently. My mentor is reviewing my solution now, and then I will rewrite and re-submit my solution next week.

The Packers beaten the Rams this week, and they will face the Buccaneers tomorrow. The contents of my diary from tomorrow is depending on that result. I hope to write happy sentences.

Sun, Jan 17, 2021

I woke up before seven to watch the game, Packers vs. Rams. I love Green Bay, so I was so glad they beat Los Angels Rams.

The offense line was MVP, even though we might miss their playing. They continued to fight in the match. This is why Aaron Rodgers is protected by the No.1 pass rush in NFL.

Another game, Bills vs. Ravens, was held after this game. As well as last year’s playoff season, It was a tough game for Lamar Jackson, one of the best quarterbacks. Some fans might say, “Jackson can’t play in an important game.” He is capable of having a Superbowl ring, but he might leave the field without it in his career.

Mon, Jan 18, 2021

My baby boy turned 9 months old, and is able to eat harder foods than before. He also got too large for his car seat, so I took off the back so he would have more space.

Today’s playoff game in NFL is two, Chiefs vs. Browns and Saints vs. Buccaneers.

Kansas City leaded Cleveland with over 10 points in the first half, but Cleveland was closing within 1 possession after Mahomes was out with a concussion. After 2-minutes-warning in the final quarter, Browns would get a chance to come from behind if they stopped Cheifs offense. But actually, Henne, the backup quarterback scrambled for 13 yards and completed a short pass, then got a winning first down.

This season’s third match between Saints and Buccaneers was watched by all NFL fans. I expected New Orleans to beat Tampa Bay, but Brees made 3 intercepts - Though, some of them were the receiver’s fault, and They left the field.

Now, my favorite team, Packers will face Buccaneers. Green Bay was literally beaten in the regular season. Rodgers and his teammates now have a chance to get their revenge for their defeat. I hope the Packers will beat Bucs and go to the Superbowl.

Thu, Jan 19, 2021

I took my baby boy for a walk in the evening today.

I heard that Babies like the same route. While, I had been taking him to difference places to make him fun. I learned that babies hope to see the same view when he comes to the same place.

Wed, Jan 20, 2021

I woke up before seven. Because my baby boy did at about six. He usually sleeps little, but today, he was sleeping for over 2 hours in the afternoon.

I tried AtCoder today. I could solve basic tasks, but couldn’t do advanced tasks at all.

At night, I posted a article about the last week’s playoff game, vs. Rams. I will have to write a preview of the Buccaneers game, until the game is held. I will watch Buccaneers vs. Saints at first.

Tur, Jan 21, 2021

I wrote a preview of the Conference Championship of NFC, Packers vs. Buccaneers. I will write that details tomorrow.

In the afternoon, My family went to the park. We bought some foods in the nearby bakery and had them in the park. My baby ate a little piece of a pain de mie.

I solved Rust tasks, too. Today’s task is a little difficult, so it took about an hour.

Fri, Jan 22, 2021

My wife went out in the afternoon, so I took my baby for a walk in the nearby park.

He seemed to figure out that I picked up his toy when he threw it. Then He enjoyed it, so he threw it time and time.

At night, I started to learn Concurrency. It seems so difficult, so I will study for a week.

Sat, Jan 23, 2021

I have been studying Concurrency with Rust since yesterday. But I can’t figure out the solution to the sample task. I want multi-threads to share the mutable value. But I can’t implement it like that but create the value in each thread, so it doesn’t process correctly.

The day after tomorrow, we can watch the game, Packers vs. Buccaneers. It will be the best game in this season because each No.12 is “GOAT.” In Japan, They will hold that game at 5 AM. Therefore, I started to go to bed earlier today so that I can get up when the game begins.
