Kanban is another word that is currently popular among corporate flocks, I mean folks. So here is a quick guide on that.
- Kanban is a technique of categorizing, scheduling and displaying the work output of a project team.
- The Kanban method originated in Japan through the Toyota Production System (TPS) and uses a feedback system to manage store inventory based on demand .
- Software development teams can use Kanban techniques for enhancing their development pipeline and simplifying project management.
- The simplest form of Kanban can be applied as below.
- All phases of the project such as specification, design, development, testing, and deployment are each given a slot on a Kanban chart.
- Each slot is further divided into smaller slots based on status of a single feature/task, such as planned, ongoing, and completed as shown in the diagram.
- Work-In-Progress or WIP limits are allotted to each slot. This is the amount of maximum items allowed to be pending in any one slot.
- The tasks are then mapped on the Kanban board as they traverse each stage of software development.
- Whenever a slot is filled to its assigned WIP limit, team members working on other slots can then help move the pending items forward or focus on other activities until the backlog is cleared.
- This pull-back helps reduce spikes in the software development process.Download this post as an image
The corporate sector spews a lot of business jargon and buzzwords. Scrum is one such word. For people wanting to understand the meaning of scrum without devoting a lot of time to it, here it is in its most distilled form.
- Scrum is an agile project management framework.
- The main objective of scrum is to render project management simple and flexible.
- As per the diktats of the agile method, testing is a part of the process and not a separate phase.
- The scrum team consists of three roles drawn along the lines of their respective responsibilities as given below.
- the product owner – an individual responsible for decisions related to the product
- the development team – a team of executives working on the product
- the scrum master – an individual orchestrating the project management
- The entire product lifecycle is divided into small timed events called ‘sprints‘.
- Each sprint starts with a single preparation meeting for selecting the requirements to be advanced in that sprint and the plan for doing so.
- The progress of the sprint is monitored by using any of the following tools.
- the testing carried out to verify the goals of the sprint
- a daily scrum meeting at the start of the day (status meeting)
- a sprint burn-down chart and/or a scrum task-board
- A sprint ends with a sprint review and a sprint retrospective (lessons learned).
- The Scrum method includes the following main artifacts.
- a product backlog (potential requirements)
- a sprint backlog (requirements selected for a sprint – input)
- an increment (the actual code/functionality for a sprint – output)
- the sprint statistics (used to monitor the sprint)
- If a sprint is cancelled, the incomplete backlog items are added back to the product backlog. The completed items are reviewed and released, or kept back for release in the next sprint.

I am going to rant some on this post before I get to the solution. I have been a fan of Ubuntu Linux for a long time. In fact Ubuntu was the reason I started using Linux. But ever since Ubuntu 11.04 (Natty Narwhal) came out, I have faced some usability issues. I like the new Unity interface and I think that it has great potential. On the other hand Gnome is progressing on its own path of GUI evolution. However, mixing both of these GUI is not working out for me. In my opinion, this mix resulted in a mashup of two very diverging approaches of handling linux GUI. The bottom-line is that I have decided to wait on the fence until this GUI battle is over and then root for the winner later. So I decided that I need to go to the next level of geek-dom and install a minimal Linux distro. My distro of choice is Crunchbang, just because. Anyways, it is a fun little distro and I still keep my Ubuntu Linux on a separate partition lest I need it someday.
Enough of that though… as the title states, this post is about a shell script to put an end to all the annoying system beeps you get in Crunchbang linux. The script is given below. (Or you can get it using the Pastie Link) Copy and paste this to a file (say ‘beepoff.sh’) and make it executable by using the following command.
sudo chmod a+x beepoff.sh
Next run the script with root privileges with your username as an argument. So for example, if your username is ‘uname’, the command would be as follows.
sudo ./beepoff uname
This should get rid of almost all the system beeps. Please note that the script is just a compiled version of a solution that I found here on the Crunchbang Forums. So if you prefer to do the typing yourself, you can make all the changes in the forum manually.

echo "login sound already off from gdm"
Also, an easier but riskier way of getting around the annoying system beeps is by disabling the pc speaker in BIOS. However, I do not know what the implications that would have on your computer. (For example, would the computer beep if you fall asleep on the keyboard? 🙂 or more seriously if the processor cooler fan stops working?) Also, I dual-boot my machine and would like to keep configuration settings separate for both OSes.
This is a sarcastic look at the state of Indian politics today. The problem is that it is true.
First you should ask yourself, are you serious about it? Politics is hard work. Start by noting important points in your notepad such as… when was the last time you committed a murder? How many kids did you beat up in your school? How many teachers? Passing even one of your school exams without copying your answers instantly disqualifies you. Hell, even passing disqualifies you. Being intelligent disqualifies you. Stop using the computer immediately. Otherwise the only chair you will sit on will be the one in front of your computer. … If you never participated in college elections, and by that I mean if you never had attempted murder charges on you when you were in college, that disqualifies you. Never having owned a gun disqualifies you. Never having fired one instantly disqualifies you… Get more weapons… use them… at least on endangered animals if not on men and women and babies… If the only knife you own is the one in the kitchen… please do not choose this career… if ‘die evil onions’ is a phrase that has ever come to your mind… you will never do well in politics. I would suggest you completely give up studies and take up some form of a drug habit and work out three hours a day. Try to beat an innocent man daily for starters. Trust me, it will help. Try to hit a petrol pump as well… How are you going to rig elections and capture ballot boxes if you can’t hold up a stupid grocery store? Maybe you should also become a ladies man if you know what I mean… they say it works wonders. How can you ever enter politics if you think all races are equal? And you should not just hate other races… you should be willing to bash their skulls with blunt weapons… for it is always ‘their fault’. If you even once think it is your fault… that spells instant disqualification my friend. Claiming to be a ‘defendent’ of a religion, or willing to give up your life for a religion helps, but you should never actually be willing to give up your life for religion. In fact, you should be willing to strap a bomb to the chests of the people that follow your religion and send them to explode. If watching them do this very thing does not delight you. Maybe you should pick a softer career such as an in the armed forces. You should also be willing to kill the leader of your own religion and claim that ‘they did it’ at the right time. In fact you should always claim that ‘they did it’. ‘They’ can be anybody you desire to get beaten to death in broad daylight. What? You don’t think anyone deserves to be beaten to death? Pack your bags and go home… I just hit the buzzer to disqualify you.
Loving money is a necessary condition for holding any post in any government but never sufficient. And by loving money, I mean you should be willing to beat up blind beggars to steal their coins… In fact try robbing people as a pass-time. If you succeed, you have another career choice, if you get caught and appear on national tv.. Great! You are off to a flying start already. If you are not that great at robbing, that is always an incentive to print your own money. So some form of technical background may help… but it is rare not to have a technically capable friend in India whom you cannot kidnap or blackmail to do your work for you these days…Bribing people always helps… Bribing cops or anybody for that matter is also a necessary condition… but don’t get too good at it. How will you take bribes if you give them??? If you are better at giving bribes than taking them.. try your hand at some illegal business maybe… but not politics… On the contrary, having an illegal business background helps a lot in politics. You could use your ill-gotten fortune for funding your campaign. Or you could just take a bribe from a friend to facilitate his/her illegal business when elected. But then the funds are always limited in these cases. The advantage in the latter case however is that you can always backtrack on your promises. Which brings me to probably the most important point of all!!! Lying is an absolute MUST in politics! Jot that down in bold letters in your mind. Lying with a straight face is a thing of the past. You should be good at lying with an emotional face and crying out emphatically to make a point you never ever had, to succeed in politics. There are many that have done quite well on this one ability alone… Always lie daily to practice this. Lie to your parents, lie to your friends, lie to your teachers, lie to people unknown to you. Lie to anybody you come across. Manipulate people into committing crimes. A little pedagogy goes a long way in politics. Lie to your significant other/others(+1point). Fake a prayer to God. Stand in front of the mirror and lie to yourself. If you don’t see the guy in the mirror clapping in awe, try again. WHAT??? Did you say you cannot lie??? What a big waste of my time?!?! Why are you even reading this then??? What were you thinking? I write this awesome guide and this is what I get. baaah… I am better off manipulating my resume.
