Spacemacs Ctrl-i fix

Fri, 24 Mar 2017 09:07:41 +0530

Spacemacs uses Ctlr+o to move backward to the last edited location and Ctrl+i to move foward after going back using Ctrl+o similar to Vim.

I found that Ctrl+o works but Ctrl+i doesn’t moves forward through the edit locations. I had the same issue in OSX/emacs 25.1 and in ubuntu/emacs25.1.

Searched the net and found this helpful issue page – https://github.com/syl20bnr/spacemacs/issues/5050

We have the troubleshooting steps there

(lookup-key evil-motion-state-map [C-i]) ;; should be evil-jump-forward
(display-graphic-p) ;; should be t
dotspacemacs-distinguish-gui-tab ;; should be t
(lookup-key key-translation-map [?\C-i]) ;; should be spacemacs/translate-C-i

In my system dotspacemacs/user-configcemacs-distinguish-gui-tab is set as nil.

How to create custom profile ID in googleplus

Thu, 29 Sep 2016 04:30:51 +0530

I was writing my blog and added a link to google plus in the sidebar. I wanted to make a human readable/rememberable Id to use for my google plus page.

I guess, planning to {use|add link} to google plus is a bad idea. I googled to find the steps to create a custom profile Id and landed in the documentation page – Get a custom URL for your Google+ profile

I tried following the steps and surprisingly it didn’t worked, I trusted google so much that I thought I may have did some mistake and repeated the steps one more time but still it didn’t worked.

Automating hugo blog deployment to github pages using travis-ci

Tue, 27 Sep 2016 03:35:35 +0530

Here are the steps I took to build and deploy my blog automatically using hugo and travis-ci to github pages

I assume a hugo blog is already created and exist

Create .travis.yml file in the project directory with the following contents

 language: go
 sudo: required
 git:
 submodules: true
 install:
 - go get -v github.com/spf13/hugo
 script: bash ./deploy.sh
 notifications:

Generate and encrypt github token

Good Font for Spacemacs

Sat, 03 Sep 2016 14:25:00 +0000

Spacemacs recommends using source code pro as the default font, infact this is the font set in .spacemacs file. If the font is not availale it is substituted for some other alternative. To find the font in use do C-u C-x = on my mac it was using Menlo font. DejavuSansMono looks better than Source code Pro on ubuntu and I switched to it in my ubuntu system. A list of top programming fonts can be found at Top programming fonts

Django development on OSX using emacs

Wed, 30 Oct 2013 13:16:00 +0000

I started following the Django tutorials by arun. I wanted to know about the related classes and quickly look into docs for the things that I code, I wanted an environment that is nice to newbies, helping with code completion and easy documentation lookup. I searched and found a huge list of options. Since I was begining with Django I wanted an environment that is much easier to setup, my first choice was pycharm, but unfortunately the community edition of pycharm doesn’t support Django - see this.

Running a Hacker news clone

Mon, 21 Oct 2013 15:25:00 +0000

I very much like the presentation of hackernews when it comes to understanding and making sense of the discussions quickly. It is a lot easier than reading pages of forums to get the main ideas of the discussions since the top comments and active discussions bubble to the top.

I wanted to run a site for discussing and sharing information that are useful for people working in techparks and the format that immediately clicked in my mind was the hacknews style. I began writing my own clone based on the work of people from hackerschool but it lacked the polish and look to make the people trust and even sign up, I had send invites to few of my friends to try but the turnaround rate was quite low.
