SIGTERMS and SIGKILLS

I finally know what the above two words are and how to use them on a Linux machine.

SIGTERM - Send an application a signal to terminate itself the way it normally would, i.e. let it pack its bags like it does. A request to empty its place on RAM.

SIGKILL - Just kill the application. No bullshit. Shoot it with the sniper. No confusions.

How to use them:

You need to find the process id for of the app you want to kill -15 or kill -9, i.e. terminate or kill, respectively.

to find the pid (you can just type part of the app's name here):

pgrep appname

or, if you know the exact console name of the app:
pidof exact_appname

Then, kill that app

kill -9 pid

Or, politely ask it to terminate

kill -15 pid

There!

Feeding my organs the power of Vim

It was only a matter of time that a Linux enthusiastic soon-to-be programmer starts to learn about Vim, right? I did not start exactly voluntarily, though.

It started when I had to work on a course's project (hint: pset3), but I was not quite feeling like doing it. So I began thinking about what other things to learn without using too much of my brain's resources (it was feeling lazy). I wanted to learn something while also letting my brain chill-out. And with that thought I began playing around in bash and executed vim for some reason, only to find that its not installed! :O (Side Note: vi was installed on Ubuntu).

A little Quacking afterwards made me try out vimtutor, and et-voilà, I'm hooked. I have to say though, the learning curve is quite steep right now.

Mozilla Clubs

What are Mozilla Clubs? To understand that, let’s have a primer to Webmaker and what Mozilla wanted to achieve with it.

The Webmaker project came in to this world as a means to learn and share knowledge based on the web. Since we have been becoming ever so dependent on the web, it becomes important to understand the web better. For example, what price may you really be paying if you are using Internet.org for free? What rights do you have over your Internet Provider? And, can you make your own things on the web? If so, how? Thus, the “Webmaker” initiative was born so that everyone was in-the-know and everyone knew to make things in it. Eventually giving people the power to shape it for the better and for their own good.

To give this initiative a massive boost, Maker Parties were released. Maker Parties are events that happen every year globally from June to August. In this period of three months, citizens of the world gather in parties to make things on the web; learn more about the web and to share their knowledge about the web. This initiative became hugely successful; from taking place in developing countries like Bangladesh to taking place in Obama’s own residence in the White House.

But none of this were free of problems: Events were being done successfully; people were becoming more aware and interested about the web; but there were no follow-ups being done, or were being possible after the events. Even though all of these were being done by the huge voluntary community Mozilla has all over the world, could this be made better? Could there be constant participation on teaching and knowing about the web? Could there be an easier way for the students attending the events and the mentors to stay in touch? Could this problem of “sustainability” be solved? Another problem was that majority of the events' duration was spent introducing the participants to three tools Mozilla developed to make “webmaking” easier. These three tools are superb but the participants became so involved in using them that most of them couldn't recall Mozilla's main objective in doing this –- making the web better.

So the heads of the Mozilla Foundation sat on meetings and on came the inception of Mozilla Clubs. So what really are Mozilla Clubs? Mozilla Clubs are places where people can go to read, write and participate on the web. This will be completely done by volunteers making clubs at their hangouts, schools, local parks or anywhere they want. The idea is that there be a place, or a group of people to whom anyone can go to discuss, share knowledge, and make things on the web. This does not mean that these clubs will be exclusive to sharing knowledge about the web only. There may be people who are interested in tinkering with an Arduino. There may be people who do not know how to use computers properly, let alone the Internet. All of these people can come to a “Mozilla Club” to have a friendly environment to learn things about computers as they will eventually lead to a capability of understanding the web and making it better.

So how are the Mozilla Clubs going to do these, you might ask? They are going to do these through what is called Connected Learning. Connected Learning is a way of learning that is a little different from that of a school. In a school, there is normally one teacher explaining their subject but in Connected Learning there are people from different professions and age groups all teaching and learning from each other. This kind of learning uses any array of resources available, not limited to books only, and the act of hacking ideas and resources is strongly encouraged.

Each club will have a Captain and all the clubs within a region will have a Regional Coordinator. The captain is responsible for keeping the boat afloat, if the club is on a boat and the Regional Coordinator will be there if the Captain needs any advice or if he is confused. It is not important for the Captain to notify everything to the Regional Coordinator as it is enough if he just shares a talk when he is confused.

Now, does a person need to have any qualification for opening a club? No! Anyone can start a club almost anywhere. It is also not important that your club members need to be super knowledgeable about anything. The club is, in the first place, made for exchanging knowledge and learning together.

The clubs will receive certain curricula given to them from time to time by Mozilla. The captain should let the club know of the curriculum and they have the option to choose to follow or not to follow. In any case, receiving curricula should help keep the club advancing and the activities exciting.

So if you are in a Firefox Club, do you need to be in a Mozilla Club too? And what is the difference between these two? It is up to you if want to be in any club at all. Firefox Clubs have an obligation to promote certain Mozilla products in their university/college. Mozilla Clubs have no obligation to promote any Mozilla products and they can play with anything as long as the ultimate goal is for the web. Mozilla Clubs is also more permissive in a few factors, like:

  • You don't need to be aged 18 and up.
  • You don't need to be in any school/college.
  • You have no obligation to promote anything(although please do promote the web).
  • You don't really need a designated spot for a club.
  • You don't even need to have 'Mozilla Club' in your club's name.
  • Activities done in the club will not be exclusive to web only.

You can also see a list of existing Mozilla Clubs, register your own Mozilla Club and see about Maker Parties here. So if you have an urge for all things computer and the web, join your local Club at the earliest and remember it is not to teach only, but also to empower.

UI/UX Workshop on Firefox OS and Mobile Apps

After a successful launch of Firefox OS in our country, the Mozilla Bangladesh community has been involved with many a developer engagement activities. As well as doing training sessions that encourage people to code on the web, they have also been showing ways of how to develop for the emerging market of Firefox OS.


Firefox OS Keon


From long before an official launch of Firefox OS, a great number of mobile applications from our country have been submitted to the Firefox Marketplace. But it has been seen that most of the apps which got submitted to the Firefox Marketplace from our country lack a good honest rating in terms of the experience of a user and good overall looks. So to improve this situation, on the 21st of November, the Mozillia Bangladesh community aranged an event named Workshop on UI/UX design for Firefox OS device, and it took place at the Bishwo Shahitto Kendra.

User Interface Design

Sashoto Seeam, Delta Ashfaq and Sekandar Badsha, all from Mozilla Bangladesh, were the co-rganizers of the event. Nasir Uddin, E.A Siblu and Mushfiqul Islam, all of whom are experienced designers in our country were there as the speakers to share their expertise.

The event covered from explaining the basics of UI/UX design to a good understanding of typography and color schemes to showing resources for finding inspirations and tools for designing an effective and nice loooking app.

Later, Sashoto Seeam discussed about the UI of the Firefox OS devices, and how best to build apps for it. He also explained the style guide provided by Mozilla that designers can use to make native looking apps.



The session was then wrapped up by Anisur Rahman and Salman Rahman Desh, both from Mozilla Bangladesh, who discussed about the Firefox Marketplace and how to submit apps there, followed by explaining the ways to earn by making apps. They also took questions from the audience and showed how to turn the designs into code.

There were over a hundred participants at the event and we managed to interview a few of them near the end. Most of them were seen having good remarks, with a graduate student saying, "Some great information on how to design for Firefox OS was shared today. This event was as good as the previous events I attended from Mozilla Bangaldesh."

A day spent learning PHP! :)

Ever since LetsLearnCoding's first event, eager learners of the web like myself have been waiting with great passion for their next event, for it was to be done on a popular server-side scripting language for web development – PHP.

We had hopes for a good day and we weren't disappointed as the event was carried out by Sumon Selim bro. He planned the event to start from the very basics, Getting started with PHP and follow right up to OOP in PHP so that the event becomes helpful for the very beginners and intermediates to PHP alike.

The event started at 12 PM and Sumon Selim bro carried all the way till 5 AM. Now thats a long streak!! Though, we had lunch and snacks break in between, but they were short ;) I can honestly say that Sumon bro definitely had fun teaching us as teaching is something he quite likes, and us, the audience he got were very attentive.

The attention of the audience were proved more than once as they won stickers and badges for themselves as they answered to quick questions... But they were not the only goodies LetsLearnCoding had to offer. During the end of the event, three licenses to PHPStorm were given for free to three individuals who were able to answer particularly tougher questions based on the day's event.

But, Sumon Selim bro was not alone on this great feat. Anam bro did the anchoring in between; there were Ahmed Firoz bro, Ashraf bro, and me as the registration team; Asif bro helped with snapping some great pictures and logistics, and Akash bro for the registration, banner and logistics.

The three licenses of PHPStorm was sponsored by JetBrains. Thanks to HubDhaka and all the other sponsors for their great support.

At the end, the day went so great that Sumon bro was wondering what do now that he had taught us some PHP.

The pictures to the event can be found at facebook now, they may be uploaded to flickr soon.

Maker Party at Old Dhaka, '14

Its a wonderful chance to be able to teach the web to students who are already learning about computers in an ICT solutions company in Old Dhaka. Thanks to i-mesh for giving us the chance!

We had 20 very eager students who were looking for a great day learning about computers but a little unsure of what we would offer. To clear their confusions, Bellayet Hossain started off with who we were and also our mission for the day... which was to have a party learning about the web and making things on it.

I continued afterwards with a video that makes explaining our shared global mission and Webmaker's part in it very easy and interactive. I am glad to say the reception from the participants were great as they recieved stickers and other #mozilla #swag items by answering to our quick questions.

After showing them the video of Maker Party, to get them to their partying spirits, we started off by having them make their very own webpages on the Internet! Thanks to fuzzyfox for making remixing a beautiful about me page so easy.

They got a nice introduction to X-Ray Goggles, the tool they used to remix their own 'about me' pages, and now they were off to remix other pages on the Internet. They were very excited but they could only do so much as we didn't have much time on our hands.

We were however able to make them more aware of their privacy and security on the web during the small time we had and a quick Q/A session after that got them winning lots of Maker Party goodies for themselves.

The event was organized by Bellayet bro, and helped to facilitate by me. Thanks to i-mesh for granting us with the event. Credits to Mahir for making that intro video. And thanks to all us community members for... doing what we are doing.
