A pretty common pattern to do this in software development is to create a new shell script which is sourced manually every time the project is worked upon. The benefits of this approach, as compared to storing everything in the global shell config (~/.zshrc or ~/.https://bitbanged.com/posts/ctf-elf-binaries-and-magic-bytes/Mon, 01 Nov 2021 00:00:00 +0000utkarsh@bitbanged.com (Utkarsh Verma)https://bitbanged.com/posts/ctf-elf-binaries-and-magic-bytes/I had a spare weekend so I particiapated in a CTF competition conducted by my college’s CS club. In the event, one challenge really stood apart and hence I’m writing about it. The challenge #On the website, a ‘PNG’ file was provided initially, called test.png . This file was the only clue to the flag. My approach #Given the fact that only a file was provided as a clue, and that it wouldn’t open using an image viewer.https://bitbanged.com/posts/how-to-exploit-eternalblue-vulnerability/Sun, 13 Sep 2020 00:00:00 +0000utkarsh@bitbanged.com (Utkarsh Verma)https://bitbanged.com/posts/how-to-exploit-eternalblue-vulnerability/This article is meant for educational purposes only, gaining unauthorized access to machines is a serious offense and this article, website, or the author, in no way, promote such behavior. Introduction to EternalBlue #EternalBlue is the name given to a software vulnerability on Microsoft’s Windows operating system. It is an exploit that allows cyber threat actors to remotely execute arbitrary code and gain access to a network by sending specially crafted packets.https://bitbanged.com/posts/how-to-use-inline-svgs-with-hugo/Tue, 14 Jul 2020 00:00:00 +0000utkarsh@bitbanged.com (Utkarsh Verma)https://bitbanged.com/posts/how-to-use-inline-svgs-with-hugo/I started developing websites a couple of years back, and I still remember how slow my first website was! The slowness owed to poor asset optimizations on my end. It turns out that delays of a mere second can result in you losing a great deal of traffic . So I started prioritizing performance during web and learnt some tricks of the trade as I kept progressing ahead. One of those tricks, not actually, is to use inline SVGs instead of icon fonts.https://bitbanged.com/posts/how-to-hide-i3wms-title-bar-properly/Mon, 30 Mar 2020 07:49:31 +0530utkarsh@bitbanged.com (Utkarsh Verma)https://bitbanged.com/posts/how-to-hide-i3wms-title-bar-properly/If you consider yourself a Linux nerd, chances are you must already be using i3, or at least know of it. For those who don’t, i3 , often referred to as i3wm, is a lightweight window tiling manager which has earned its name in the business thanks to its speed, and a nicely done documentation . I’ve been using i3 for over a couple of years now, and recently switched to i3-gaps , its fork, for a fundamental reason, it looks better!https://bitbanged.com/posts/year-wise-population-graph-using-scrapy/Thu, 26 Mar 2020 00:00:00 +0000utkarsh@bitbanged.com (Utkarsh Verma)https://bitbanged.com/posts/year-wise-population-graph-using-scrapy/I have always been amazed by phenomena like entropy and chaos. At the same time, I feel pleased while seeing straight lines and symmetric curves. So, I love to find patterns in chaos. Have you heard about the Bell curve ? Almost every natural phenomena if studied a long time follows the Bell curve. I thought, why not plot the world population vs year graph, and see how much it matches.https://bitbanged.com/posts/how-to-install-mongoose-os-on-esper-or-esp32/Sun, 28 Jan 2018 18:59:43 +0530utkarsh@bitbanged.com (Utkarsh Verma)https://bitbanged.com/posts/how-to-install-mongoose-os-on-esper-or-esp32/Recently I’ve got my hands on the craved-for IoT ESP32, thanks to DFRobot , and have been tinkering with it ever since. I’m really amazed by it since it packs both Bluetooth and WiFi in a small yet powerful unit. Since I received the MCU rather than the module, so, to use it, I made myself a breakout board named ESPer(because, why not? :smile:). Feel free to check out its Instructable over here .https://bitbanged.com/posts/the-dpdt-push-switch/Tue, 04 Jul 2017 00:00:00 +0000utkarsh@bitbanged.com (Utkarsh Verma)https://bitbanged.com/posts/the-dpdt-push-switch/The DPDT Push Switch(Double Pole Double Throw), more commonly known as 6 Pin Push Switch, is nothing but a combination of two switches placed together in a single unit. Unlike momentary or tactile switches, these switches maintain there switching state, that is ON or OFF until they are triggered again. For example, if I push it once so that it’s turned on, it will remain in the ON state until I push it again.
