UML

Finally a book on UML that makes sense to me (and is short enough so I was willing to read it, in one morning).

Milestone 1: requirement review

Everything starts with an analysis of the problem at hand. One thing learned and I'd like to clarify is requirement — it ...

A dream

I had a dream, as vivid as it can be, that I was walking next to you. You were wearing the black dress, the one you look so refined and elegant in. I reached out to your hand, but you retrieved it inside your sleeve, and only after a couple ...

Not feeling well, today

But this screenshot from kiki brightens my day ~~

I miss 米粒儿和米答应. Sometimes I feel really sorry that I feel like I have walked out of their life. Maybe she feels that way, too. But then I know I didn't. I didn't mean to, and I did what I ...

Waste of mind

Wow, this is quite unbelievable! I read a line:"A mind is a terrible thing to waste." (looking it up, there is an NPR!) yes I have always remembered this line, because it is so true — despite that I have been losing faith of human being in general, I do ...

Development

This is a quite fascinating argument, and quite unexpected when I'm reading this book, Mosquitoes, Malaria and Man.

As for typing public health efforts to development, WHO takes its stand on popular but treacherous ground. One reason eradication failed, the argument goes, is that governments were not convinced it ...

China witness

I have seen this book on Reader's Corner's shelf for sometime, and never felt I should pick it up and read. The book didn't feel like a kind of book I would like to read, "Personal interviews!?" I thought ot myself, "that is a common cheap method ...

Generalization

I have been thinking, is generalization good, or bad, or inevitable? I kinda of wonder that looking at something, especially something new, in a generalized term, is actually inevitable. Watching Noah learning things since young, he has to generalize things in order to recognize anything — this is a dog, that ...

Server RAID

If you are like me who dislikes any GUI and mouse clicks, CLI via a SSH session to IMM is a fun way to get things done. This one shows how to config disks into RAID.

CLI manual is here.

usage:
    storage -config vol -option [-options] -target target_id
options:
    -remove ...

System capability model

Ah, DCIM. Infrastructure needs to be managed, but then, what does it mean? Borrowing from wiki, a view can be:

  1. Asset Management
  2. Network connectivity Management
  3. Environment Management
  4. Energy Management
  5. Change Management and
  6. Capacity Management
  7. Computational Fluid Dynamics (CFD) Integration[17]

This type of view is based on an attribute of ...

Lights

Walking out from a shadow after a morning gym session, my eyes were blinded, for a while, as if I was walking across a border between two worlds, a new life? a re-birth? It felt good, when the summer heat hit on your skin that has just emerged from a ...

Network switch

Network switch is a gold mine. You will need (ip, username, pwd) to get to it, using Telnet(!). Your friend is pexpect, but even that gives you jinx sometimes when each switch can return you some random garbages once a while that makes session.expect("your regex pattern") to time ...

Screencast

Introduce tools to create screencast.

Netbox revised

Netbox is a nice level 1 tool (for levels, see capability model). But we need more. Managing a lab or a rack is more than level 1. On top of all these, we talk about automation, which implies capabilities at least to level 4. Therefore, we used Netbox code as ...

Moment of quietness

It's quiet here. Office is deserted due to the upcoming long weekend. It feels rather strange. Listening to the song makes me to think of you, and the days agains. Mr.Makato is still here. He is always here early in the morning, and leave late at night. Is ...

Must do, maybe

I just had a thought — many mid-age women claim that they feel the best of themselves in this age band because they are independent, self-sufficient, less anxious, not that they have fewer troubles in life, but they view them as a matter-of-fact, just deal with it when it comes.

On ...

How many can one love

Train is an interesting, amazing thing. Never thought I will be sitting on a train (CalTrain) which brought me a feeling of riding train in China.

I haven't expected to see your messages, because I think it is the right thing to do that I should disappear from your ...

Technology and society

I have been thinking quite a bit about technology, and its relationship to society. I used to be a firm believer, and a practitioner, of technology. After all, it is what I do, and I actually enjoying writing code and drawing diagrams to analyze a problem at hand and to ...

Sadness

Yao Han introduced me to this movie, at the time when we first met and were in love. I was 27, she was 19. I don't know how many times I have watched, listened to, and dreamed of, this movie. Each time it touches me deeper and deeper, makes ...

Finite anxiety

I was thinking. People get anxious on topic like bitcoin, why? Some talk says because the feeling of "loss" is greater than the feeling of "gain" even though the amount is the same. This has been proven in stock books. But then, things like bitcoin, or success, is NOT a ...

Mid night

Since coming back from Spring Break trip, my body and mind have been really tired. Work is progressing fine. A lot of new things to learn, but overall are quite manageable. But work is just, work. I was sitting in this good looking, big kitchen 2 o'clock in the ...
