Ubuntu Chromium DEB file are actually snap wrapper

Fri, 30 Jul 2021 12:22:25 +0800

The screenshot taken is the latest rev:head (currently when the post published) of chromium-browser/focal package files repository. I really surprise about this kind of packaging. Oh my God, how comes this is allowable?

Seems it start putting and using wrapper to use snap on rev:1505, correct me if I wrong because I don’t use bazaar source code management so much compare to cvs, mercurial and git.

Control Your Snap Package

Press here to skip the rant

I checking my email today and saw Bret Busby posted on Ubuntu-users mailing-list asking about “How do we disable the snap stuff” and likely it trigger some Ubuntu kipas-susah-mati replies when he typed:

As this snap stuff can not be trusted to not make unauthorised changes , and, cannot be trusted to not sabotage the system operation (this unauthorised snap interference probably explains the error messages that I have been getting, about incomplete and partial upgrades and resultant systems instability across my systems), how do we disable this malicious snap thing?

Fedora - dnf history with fedora-repos-archive

Fri, 01 Jan 2021 05:52:00 +0000

Fedora use dnf as package manager and dnfhave option to see transaction history and undo/rollback the transaction.

For example I updated icecat web browser via dnf update icecat to newer version that just released and then after installed the newer package, I can check and see my last transaction history :

bash

$ dnf history info last

Sending JSON data file using CURL to API endpoint

Mon, 30 Nov 2020 10:23:00 +0000

I developed warehouse system and use restful as communication method between our software and client software. We let end point of our system to talk each other with API designed.

For simple and small test using Postman or SOAP-UI is enough for me but to when to test this system with massive data via API is quite headache, plus the mock features on Postman limited and not “mocking” enough as I want.

Posix - Speed up "find" + "exec" command (recursive)

Sun, 08 Nov 2020 11:19:00 +0000

I learn some trick today on how to speed up find, exec command. Let check this out:

gist · RobbiNespu View on GitHub ↗

# let see how many files we have
$ find . -type f | wc -l
36367

# lets check every file status
$ time find . -type f -exec stat {} \; > /dev/null
real 0m40.107s
user 0m14.381s
sys 0m26.410s

# lets check every file status
$ time find . -type f -exec stat {} + > /dev/null
real 0m1.281s
user 0m0.626s
sys 0m0.656s

Wow that’s quite a huge difference! Impressive! All we did was swap the \; for a +.

Setup python 3.6 enviroment with virtualenv

Tue, 23 Jul 2019 09:00:00 +0800

My wife ask me to convert few of PDF files to Excell spreadsheet. I did same thing last year by creating some small scripting program in python to do the conversion, but I don’t know where I put my code right now. Maybe lost during formating my laptop last year..haha 😜

I am 懒 right now (guess what I wrote in hànzì) and I don’t remember how I did last time. Hahaha.. With my Google-fu skill, I found out DfTables offer free API for converting document to another format. Nice! 😬
