My Zcoin progress

I could not get Zcash to run on Debian inside virtualbox on Amazon EC2 because they do not support nested virtualization.

I tried just using AWS as the provider and using Vagrant locally, but I kept getting an error like 「this box is not available on requested provider」(using Japanese quotes because it is not an actual quote).

So I tried spinning up a Debian box directly on Amazon with Ansible. It starts and then automatically shuts down.

I have not yet tried starting said box with Amazon’s launch wizard.

My Japanese progress

I cried yesterday during my Japanese lesson. I could not stand not knowing the answer because I had not studied. Basically my teacher was quizzing me and I kept getting answers wrong because

  1. I had not studied
  2. I do not yet know the verbs
  3. I do not yet grok (in)transative in Japanese (though I basically understand the idea in English)

She suggested we switch to just reading some text and skip the grammar until I have time+desire to study again.

Work progress

I got a backup script running via cron which saves tables in smaller bundles than Entire Database at a time. Basically it saves tables by searching for a prefix. Only problem (yes the only problem haha) with my system is when I do not send a prefix, the script has to know which prefixes to skip.

two minutes after 8 hours

11:32 Friday 19 May 2017 JST

I am the butt of the joke about knowing what to do .. I just spent about 8 hours of trying to figure out why CB app was not showing images. Image server was okay, cloudfront was okay, .. was it the app caching things? I had to dig into the source of the app to discover there is a differently spelled version of CB’s domain name, call it seebee, which was being used. So pointing that oddly spelled domain to the right place fixed the problem.

still can't get shit done

15:57 Thursday 18 May 2017 JST

Today I discovered the image server had run out of space; I hadn’t created a separate volume for its cache. Got that sorted, but now need to add a cronjob to prune the space. I hope wiping files older than N days should do it, because that what I plan to do.

But why tf are some images still showing up all FFFFFF white? Well that is just on the app.. I cannot figure out where the FFFFFF images have been cached.

cannot login

07:47 Thursday 18 May 2017 JST

CB: Onece we logout,we can't login.
CB: it's a app things.

me: hmm.  I have not changed the iPhone app.. the only thing I
    changed recently was the image server.
me: I wonder what could cause it.

Steps to check:

  1. Look up my username and password
  2. thunderrabbit / ***********************************
  3. see if I can log in
  4. if not, log in to server
  5. watch the logs
  6. see if there is an error
  7. if not, (shrug smiley)
  8. if so, hope the error tells me something

I was able to log in no problem.

What’s the polite way to say show me the money when my language school is like oh can you make these tweaks to our website?

Lessons tonight were ssooo challenging for me.

can't get shit done

12:25 Wednesday 17 May 2017 JST

Man my productivity has been dismal for a while. Basically it’s cause I have too much shit going on and can’t keep the status of all my projects in mind.

Specifically, I wasted an hour wondering why one particular image would not show up, and turns out I had not yet updated my dev environment to use the new image server.

Then a tiny bit of maintenance success getting my dev environment fully working, but now it’s time to go to my next lesson.

Mt Fuji's 'recent' eruption

09:19 Wednesday 17 May 2017 JST

Today I learned from C-san that the southern face of Mt Fuji erupted in 1707, leaving a still clearly visible crater on the side of the mountain. So interesting!!

A-san showed us a satellite map which shows the hole and a river-looking thing on another face of the mountain.

I’m glad C-san remembered her homework!

snoozy commute

06:25 Wednesday 17 May 2017 JST

Arriving on time for my 7:50am - 8:50am lesson requires I leave our house by 6:25am. However, if I leave home by 5:45am, I can sit down on a train at 6:25am, and sleeeeep until it arrives at 7:30am.

Bah I do not want to type Japanese right now.

1時から、大輔先生のレッスンを始まります。先生がたくさん練習することが 大事、て。

I don’t think I should mix ます with short form て, but I don’t know how to do reported speech in long form. 言えました perhaps.

Okay so my z.cash VM ran out of memory here on my local box, so I will probably spin one up in the cloud. AWS is easiest for me, but maybe I’ll take a bit more time to find a less expensive solution. Is Linode a flat rate? Hmmmm. Maybe it’s time to get my own one of those.

12:25 Tuesday 16 May 2017 JST

Looks like I am targetting AWS, just because I can hopefully get Ansible to do all the grunt work.
