Linux meetup and the talk about protocols

Posted by Ish

Since several weeks Logan announced this Linux meetup about Open Protocols & Standards. He got inspired after attending the IETF 93 meeting that happened in Prague this year. Upon coming back to Mauritius, he thought it’d would be cool to share the experience with other like-minded folks..

Thanks to Ashmita & Nirvan, he happened to get a room for the meetup at the University of Mauritius. Thus everything was finalized for Saturday 29 August 2015, that is today. It’s been a long time since we had a Linux meetup; I could list a series of reasons but they would all be unjustified :-/ Never mind, this one was happening, I could not have missed it.

I reached the University of Mauritius at 12h30, found a parking lot, picked up my bag and went in search for room 2.12 which should be in Phase II (the building how it’s called at the university).

Logan was right outside the room talking to three girls. I just greeted him without interrupting his business. We were around 8 attendees while some were on the way. Logan started his prez at 12h45. He states there is a “problem” that dates back 20 years but very few people have considered it. He then started talking about a slow Internet situation. He explains about Bufferbloat (lag) under a network load.

Logan mentioned that when the bandwidth crosses the bar of 5Mbit/s it becomes insignificant. The real sluggishness of the internet is then due to high latency. He cited scenarios where several users in a household would suffer if they use Skype, upload documents and watch YouTube simultaneously.

Logan told us about his experiment on a TP-Link router while replacing the latter’s firmware by OpenWRT. He was able to apply tweaks that would remedy his latency issues when several users on his home network would use the internet. The discussion continued on the TCP/IP standard and Logan shared some knowledge he acquired during the IETF 93 meeting.

Around 14h30 we had a break and we went to the university cafeteria.

After the break, the discussion went more technical and Logan explained about the fq_codel implementation in OpenWRT. CoDel aims to defeat bufferbloat, which refers to an excessive buffering of packets. The latter leads to high latency and finally we see the sluggishness in network-related applications as mentioned the beginning.

Logan has shared his presentation slides for those who’d like to have a look.

That was a cool meetup after a long time :)

Reviving an old notebook with Xubuntu

Posted by Ish

Last Sunday I spent some time reviving my old laptops. Had quite some gear lying around and I decided to clean up the trash. I gave my current Acer Aspire running openSUSE 13.2 to my mom, swapped the HP Compaq 6515b with an SSD drive and loaded Xubuntu.

Next in line was a little bit of aesthetics. In fact, while exploring Evolve OS I came across the Numix Project. Thought of giving it a try. Ah, totally worth it.

xubuntu-desktop

The Numix Project offers a collection of GTK themes and icons. Get hands on those as follows:

sudo add-apt-repository ppa:numix/ppa
apt-get install numix-gtk-theme numix-icon-theme

Hit the Appearance dialog and set the Style and Icons as Numix.

xubuntu-numix

One more tweak for the day. Though font anti-aliasing is enabled by default my fonts would not look good in Abiword. To fix the same I ran the Alt + F2 combination and executed xfce4-settings-editor. Went to xsettings and set Lcdfilter’s value to lcdlight.

xfce4-settings-editor

As and when I tweak the box further, I’ll be writing.

Ubuntu Jam 2015 – Mauritius

Posted by Ish

In-line with the Ubuntu Global Jam happening from 6 – 8 February 2015, we too, we had our share of jamming session at the University of Mauritius today. Due to work commitments, however, I could not put in too much energy and rather unloaded the same on Ashmita, the University of Mauritius Computer Club president, and a very good friend.

ubuntu_global_jam_badge_v1Though we had a tight schedule of just a couple of days, she managed to get some gear ready for the event. I created the event on the Ubuntu Loco Team Portal. Ashmita created an event page on Facebook as well.

Scheduled to start at 10h00, I reached the University of Mauritius around 10h15. Bad weather, bad timing, but geared for some fun. On the way, I picked up Shelly. As for Pritvi, really it’s time he gets himself a mobile phone to synchronize timing. He reached the university some 15 – 20 minutes after me.

As I arrived at the caféteria, the usual geek team was busy setting up what looked like a “chapiteau”. Oh great, we would need one in case the rain pours like hell. Ubuntu Jam in the rain, that’s rare but fun.

Minutes later we had tables set up, got power and plugged our gears. I brought two laptops. My work laptop was with me, I actually carry it everywhere ^^ so I just shot a Live Ubuntu on that one. Besides I had my second laptop running openSUSE which I used to build Live pendrives.

A few curious ones showed up and I discussed Ubuntu while demo’ing stuffs on the Live Ubuntu session. Some took ISO images while many others wished to have a Live pendrive. The irony was when I had Ubuntu running on a MacBook to copy a Linux ISO on a Microsoft pendrive :-)

Kamal & Nadim were busy installing Ubuntu on laptops. It was great to see people bringing their gear for a Linux install. As far as I know, they did at least three installations.

Nirvan & Logan were intrigued as to why they had SSH issues on the university campus. They tried git-cloning using SSH and it failed flat on their face. Git via HTTPS worked though. Conclusion, port 22 (standard port for SSH) seems to be blocked. This did create some debate and it was argued that SSH is a popular protocol used in many “security-centric” applications and Github undoubtedly is the favourite code-sharing platform for aspiring computer scientists of the university.

We packed up around 13h30 & settled at the cafeteria itself for a group lunch :-)

Let’s peek into Evolve OS

Taking advantage of being at home today, I dd’ed my spare pendrive with Evolve OS. To be fair, I’m a bit late in review writing this time. Evolve OS Beta 1 got released on 26 January and I scheduled a trial the same night.… Read more ➡

LUGM Saturday meetups. What do the geeks do?

Posted by Ish

Mid-year 2013, I used to shoot about Linux mini-meetups on facebook, then they became LUGM meetups, all planned for Saturdays over an exaggerated intake of coffee. In the beginning, we would be like 3, 4, maybe 10 people attending. However with successful events like Linuxfest & Corsair Hackers Reboot, having more than 10 people in nearly every meetup was like normal.

Yet from time to time people shoot me questions about what do we do or talk about during those meetups? Some ask if they can attend even if they are still in college, while others fear they are still novice in Linux. I’ve made a colorful answer to these questions (^^,) … Enjoy it!
