2 odd things about cron tasks

Thursday, 16 Nov 2017

1) A cron task won't trigger unless you add a new, empty line in the end of the cron task list file.

2) Cron might not always be able to find an application by its short name, without its full path that is. Say, "ping". Namely, in a cron task you better use "/usr/bin/ping -c 3 something.com", not "ping -c 3 something.com" Even if you can call "ping" in the terminal with no failure by its short name.

Kaizen Japanese - 改善日本語 - is almost finished

Saturday, 30 Sep 2017

The website kaizenjapanese has almost, although not completely, been finished. Design or css-wise I like it more than the previous version. It's built in Elixir/Phoenix and I plan to switch to Ruby. I'll use a simple framework or rather gem called Roda because it's drastically simpler and more lightweight than Rails and even Sinatra.

What language is this?

what language is this

This looks like Clojure or List. Except that it's.... Perl 6. Yes, Perl 6 can be extended so that it looks like a completely different language.

Processing bitcoin payments by myself

Thursday, 25 May 2017

At omagatoki.gdn all bitcoins payments are processed by myself, namely, there's no third-party involved there at all. It's almost finished and is being tested at the moment.

Thus, it's very well possible not to depend on anyone when it comes to bitcoin or almost any other crypto-currency. And this is stunning.

30% of all words in an average video on youtube related to IT is 'so'

Sunday, 26 Mar 2017

so.... so.... so.... so... in between each sentence. so.... so.... so.... so... so .... so...

What are they all sewing? Aren't they aware of variety of other helpful words such as therefore, thus, in this/that way, consequently, as a result, hence that can be a great substitute for "so"? They're not direct equivalent of "so", however, they're pretty similar to "so" to be used instead of it in many situations.

About Stackoverlow and some its unreasonable participants

Tuesday, 07 Mar 2017

Stackoverflow and some participants in particular are being unreasonable: they like to lecture those who ask questions, especially if the one asking a question is a newbie. Or looks like a newbie with a new registered account. How come they don't realize that it takes me -- the one who asks questions -- less than a minute to register a new account on a new, temporary email, ask a question, throw my account away and register a new account all over again if there's a need?

"You come here, to your society! Therefore you're to obey our rules! The rules of Stackoverlow state:

1) First you do a google search.

2) Then you show us what you've tried.

3) Finally, exhausted and desperate, you're permitted to come to Stackoverlow and ask a question....".

My project in the Assembly language

Tuesday, 17 Jan 2017

With the capacity of being able to see similarities with and differences from other languages, learning Assembly language is now easier than it used to be a few years ago. I'm working on a project called 温泉 or Onsen. It's a DNS server working over HTTPS. I'm using NASM for it in particular and in general.

It's more or less like this -- often download is stuck at the very beginning or end. Or in the middle. But still ... stuck.
