Cimulator is a tool that can help you see you program in action. That means no more mysterious floating point exceptions, no more hidden runtime errors. With Cimulator, you can actually see your program run step by step and debug the errors as they occur.
You can change the speed of the Simulation using the slider on the top left hand side, or even pause the simulation altogether using the Pause button on the top right of the screen. The reset button, just next to the Pause button can be used to stop a running simulation, and reset everything. When...
SHARED SSH SESSIONS WITH TMUX - BEST OF TERMINAL
Since the title isn't very descriptive, let us look at what we are trying to achieve. Click the image below to view the animation I recorded. The two terminals are made to mirror each other, i.e. anything I type on one terminal will appear on the second one, and vice versa.
This won't make much sense, or seem of any use, until you realize that the two terminals need not be on the same computer. That is, me and my friend from across the country could do this...
WINDOWS 10: A LINUX USER'S PERSPECTIVE
For the TL;DR people, here is the verdict. Microsoft has tried (For the first time, it seems) very hard to actually make the OS more hospitable for both technical and the non-technical community. Features like PackageManagement and switchable desktops (Linux Workspace equivalent) actually have made Windows 10 a huge improvement over its predecessor.
So, like everyone else, in the past two days, my facebook feed was filled with posts about Windows 10. As a linux user, I tried for quite some time to ignore the posts, but then finally decided to upgrade my preinstalled Windows to 10.
The article is...
USING SSH FROM WINDOWS 10 WITHOUT PUTTY
With the recent upgrade to Windows 10, Microsoft fixed many of the things that I despised in Windows 8. I don't usually use Windows if I can avoid it, but unfortunately, some of my work requires me to use it anyway. For those times, one of the basic needs for me is an SSH client. A LOT of the time I'm programming directly on a SSHed server machine.
Till a few days ago, this meant that I had to use PuTTY everytime I had to use SSH from Windows. If you have ever used PuTTY, you'd know that it isn't...
CYTHON: BOOST PYTHON CODE PERFORMANCE
This tip is for those people who have been working on large python projects and the fact that python is a slow language as compared to statically compiled languages has finally caught up with them. This tip is about Cython, what it is and where can you use it for maximum effect.
What is Cython?
From the docs themselves,
Cython is an optimising static compiler for both the Python programming language and the extended Cython programming language (based on Pyrex).
The Cython language is a superset of the Python language that additionally supports calling C functions and declaring...
WRATH OF LINUX PACKAGE MANAGERS
We all love to characterise things as "More than the sum of it's parts". We'd like to say the same about our linux operating system. My ARCH is more than the sum of it's parts! Well.. no.
A linux system is exactly the sum of it's parts. And most of those parts are connected to the base package manager, the beast that acts like a framework, holding everything together.
Have you ever wondered what makes Ubuntu Ubuntu? Or what is the difference between ARCH and GENTOO? If you guessed a package manager, you'd be right.
You probably don't believe me?...
ESSENTIAL VIM PLUGINS
First, lets recap. Vim plugins are used to add functionality to vim. That functionality can be syntax highlighting, bracket matching, mode switching, easy file searching etc. Pretty much, there's a plugin for every functionality that is not built-in to vim.
The way of installation varies with the type of plugin manager you are using. Almost all plugins are either developed or backed up on github. Most plugin managers make it trivial to install plugins from github repositories.
For pathogen, clone the plugin in the
bundle folder in the
.vim directory in your home folder.
VIM: SETTING A COLORSCHEME
Every good text editor deserves to have a customizable color scheme. For vim, colorschemes are installed as any other plugin. Most colorschemes can be downloaded as a
.vim file. If you are not using a plugin manager, you need to copy the
.vim file to an
autoload folder inside a
.vim folder in your home directory.
However, if you are using a plugin manager, (as you should), then depending on the plugin manager, the colorscheme may be installed like a plugin. Personally, I suggest you install a colorscheme-pack. Since it makes it trivially easy to switch to any colorscheme...
PLUGIN MANAGEMENT IN VIM
What I've written in this post is my opinion, and should not be taken as fact. There may be features I don't know about, and my preference order may not be same as yours.
Here is a quick overview of the plugin managers that I've used, ending with explanations on how to use my personal favorite, Vim-Plug. You may skip the comparision section if you just want to be started quickly.
No discussion of package managers is complete without mentioning pathogen. Pathogen is one of the oldest Package Manager for vim. It simply allows you to...
QUICK INTRO TO CUSTOM VIM MAPPINGS
One of the best things about vim is its ability to create custom mappings for almost any key in all modes.
Suppose you want Ctrl+S to save your document while you are in insert mode, because pressing
to switch to normal mode, save the file, and return back to insert mode is a bit too much. According to vim philosophy, it actually is too much, and thus you can map Ctrl+S to those keys just as easily.
For this, add the following to your vimrc
inoremap <C-S> <Esc>:w<Enter>i
The command has separate parts but follows the...
