Hi Dad!

No Comments

I am not a handy man as I never inherited that skill from Daddy. I am very of wary of powertools even if I am fascinated by them. I always treat the tools with respect whenever I use them. Much like today.

I am glad to say the powertool I am using today (portable impact drill) didnt cause me harm. It was the underside of the monoblock chair that did me in and caused a mini red fountain in my  foot’s second toe. It was a perfect storm of carelessness, stupidity and timing.

I did see Daddy again in that brief 30 seconds of pain though. I squealed the same way I imagined he would have. Murmuring self-directed invectives while brimming with pain.

Sync clock with Google

No Comments

If the Linux VM was running at the time the host OS (Windows) hibernated then the clock in the guest VM will be left at the time of hibernation. If NTP is configured then the clock should resync gradually but most systems do not apply a big chunk of time correction by default.

If the Linux VM was configured with a VPN that implements a system-wide configuration then the DNS resolution might be unable to resolve the NTP server since the DNS of the VPN session will be unavailable. The alternate and work-around presented hinges on two things:

  • The guest VM has internet access at the time it was resumed.
  • The google.com domain name is already resolved and cached.

   sync-clock() {
     echo Current time before sync: `date`
     echo Current time after sync : `sudo date -s "$(wget -qSO- --max-redirect=0 google.com 2>&1 \ 
       | grep Date: | cut -d' ' -f5-8)Z"`
    }

The work-around uses the time in the google headers to provide an anchor for the correction.  This is provided as a bash function to provide user feedback if a correction was done.

Fix for crashing gnome-control-center

No Comments

The GNOME control center in my Manjaro system crashed while I was tweaking the details of the mouse settings. After it crashed, I was unable to bring it up again even after a reboot.

The solution was to reset the configuration files for it using the following command:

$ dconf reset -f /org/gnome/control-center/

After that, the control center UI is up and running again. Based on the search hits, visiting the details pane can sometimes caused the state that results to a segmentation fault whenever the control center initializes.

Pushing git branches to another repository

Leaving this here as I keep on forgetting these whenever I try to replicate a repository to a test repository:

git remote add new_repo git@gitprovider.com:/path/to/new-test-repo.git
git fetch --all --prune
git push --prune new_repo +refs/remotes/origin/*:refs/heads/* +refs/tags/*:refs/tags/*

[BftP] Deductive Reasoning FTW!

I am lifting the image below that I sent to some colleagues to highlight the power of deductive reasoning. The image originally came from 9gag.com but I am hosting a copy since this blog has been littered with broken links.

Batman vs Sherlock Holmes

The comment that I sent to accompany the email message has already been gone from the site. It explained the comics so I replicating it below for archiving purposes, with typos and all.

It’s quite easy, my dear watson.
It is Apparant that the mask is used to disguie a well-known identity from society. a man using a double life is most clearly a famous person, most possibly a rich man who can use an expensive Cavlar suit and quirky gadgets. the square jaw indicates a good lineage, perhaps a doctor’s son. the bat-motif is most likely from a childhood trauma that branded into the man’s mind as a great truth in the power that chiroptophobia has on the common man… *puff* *puff*
