Brew your best Coffee with Aeropress

Posted by Thejesh GN On March - 26 - 20142 COMMENTS

I knew about Aeropress from long time. Their website didn’t build much confidence, but then Leo always talks about it on TWIT. And I trust Leo enough. I got myself an aeropress from Blue Tokai Coffee which offers world-class Indian coffee online. They are probably the first Indian coffee subscription service where in you pay early and they send you freshly roasted coffee every fortnight. Anyway it was easy to buy and got delivered with in two days along with my coffee.

Aeropress uses manual brewing where in you add hot water and coffee on the top, leave it for ten seconds and push the plunger down. And your double espresso is ready. That’s it just 30 seconds. If you have electric heater it takes exactly 1.5 minutes in total. You can add a portion of water or milk to make lathe or Americano. It uses paper filter, so you need to change it every time you brew it. But it’s very easy to do. Also the package is so light in weight that I plan to carry it while traveling.
Watch this tested episode to see how easy it is to brew coffee. Aeropress was also featured on wired magazine. And I tried it last night, Aeropress meets all the expectations. It brewed the best coffee. And BlueTakoi probably makes the best coffee for Aeropress in India.

Bangalore Tree Survey – POC Results

Posted by Thejesh GN On March - 6 - 20141 COMMENT

Bangalore, once upon a time called Garden city, still has quite a bit of green cover. Almost every week we read a story about cutting down trees for some reason. But nobody knows the details, including the people who write those articles. I thought it would be great if you had a baseline survey of trees, which can be used for comparing, or many other stories and studies. But imagine mapping every public tree (tress in public areas like road, parks etc) in Bangalore. It will probably take years if I start doing it alone. But then there wa no way to find out other than trying it out.

So I asked DataMeet as usual. I figured that a PoC by me would be a great place to begin. Hence I installed ODK on my phone and ODK aggregator on server to collect the survey data. That was easier than I thought. Then this monday I walked around for 15 minutes to survey the trees, in an area which has lots of trees. I mapped around 18 tress in 15 minutes by walking half a kilometer. Some screen shots from the apps





Some issues that I faced
1. GPS logging is not very accurate. It has 4 to 8 meters of error, how do we fix it?
2. Roughly every tree takes 2 minutes, take a picture of tree, take a picture of leaves/fruits/flowers, geo tag. How long will it take for whole Bangalore. It has to be done by foot right?
3. Quality of pictures, depends on the time of day, camera quality, how big the tree is and patience

Some ideas, learning and questions
1. ODC is easy to use, works really well, even offline
2. Crowd source: Can we crowd source this project? We can have mapping parties. People just need mobile (no internet) and time. Once they finish the survey, they can either come to the camp or go home to sync the data
3. We can use maps (gis) to assign the roads, areas to groups/teams. Check the progress and coverage. This will help in organizing
4. Can we finish this in years time? What about delta after that?
5. What else can we do?
6. What kind of data do we need to collect live? For example Tree name can be figured later.

BMTC Bus Stop Accessibility – Part 2

Posted by Thejesh GN On March - 6 - 2014ADD COMMENTS

One of the biggest criticism of my previous post about BMTC Bus Stop Accessibility study was that the data was old. I set out to fix that. BMTC now has fairly well defined website and hence I scraped their data with ease. Now we have the recent data (Feb/2014) as per BMTC website available on OpenBangalore. Equipped with 2200+ locations of bus stops I repeated the same exercise.

Here are some pictures from 500 Meters.


Looks like most Bangalore is well covered. Reach of BMTC is quite good. Next three images show zoomed in maps. It looks like central, south, west of Bangalore is well covered.


It kind of shows the south-east of Bangalore (Sarjapur road side is not well connected). I really want to double check that point.

Trusting DataMeet

Posted by Thejesh GN On March - 1 - 20141 COMMENT

It seems Anand and I thought about the same thing at the same time. We called it differently but we settled on DataMeet because it was better. In the initial days we used to have virtual meetups on Skype, then offline. After a while we started an email list so we could discuss and then that list grew. Now major part of group activities happen on that list. It’s the life line.

datameet 0 mail

On one of those days I told Nisha “we should have a huge meetup, it would be fun”, so we could meet everyone in this area and Nisha said “lets do it” like always. Ashwani said okay for the venue. That big meetup became OpenDataCamp Bangalore, ODCBLR for short. And then it became our flagship annual meetup.

Today roughly after three years we are trying to do quite a bit of work. It involves meeting people, organizing camp, workshops etc. A recognized and registered name gives the community legitimacy and physical existence. Registered name also makes it easy to operate outside the group.

All of us wanted it to be easy on us and wanted the less bureaucratic way to achieve this so we could continue hacking, which is what we love to do. Hence the trust way. So we did that.


And now DataMeet is a trust. Other than that everything remains the same.

ಕನ್ನಡ ಪ್ರಭದಲ್ಲಿ ಅಚ್ಚಾದ ಈ ಲೇಖನವನ್ನು ಓದುವಾಗ ಅನ್ನಿಸ್ಸಿದ್ದು “ಕನ್ನಡ ಪ್ರಭಕ್ಕೆ ಏನಾಗಿದೆ?” ತಲೆ ಕೆಟ್ಟಿದೆ ಅಂತ ಅನ್ನಿಸದೇ ಇರದು ಅಲ್ವ?

ಉಮೇಶ್ ರೆಡ್ಡಿಗೆ ಮಹಿಳೆಯರ ಒಳ ಉಡುಪನ್ನು ಕದಿಯುವುದರಲ್ಲಿ, ಸಂಗ್ರಹಿಸುವುದರಲ್ಲಿ ಮಜಾ ಸಿಗುತ್ತದೆ ಎಂಬ ಕಾರಣಕ್ಕೆ ಅದು Individual Freedom ಎಂದು ಸುಮ್ಮನಾಗಲು ಸಾಧ್ಯವೆ?

ನೀವೇ ಹೇಳಿ ಯಾರು ಪ್ರೀತಿಸುವ ಹಕ್ಕಿನ Individual Freedomನ್ನು ವಿರೋಧಿಸಲು ಉಮೇಶ್ ರೆಡ್ಡಿಯ ಉದಾಹರಣೆ ಕೊಡ್ತಾರೆ?

ಎಂಥೆಂಥಾ ಸಮಸ್ಯೆಗಳಿಗೂ ಪರಿಹಾರ ಕಂಡುಕೊಳ್ಳುವ ಈ ಕಾಲದಲ್ಲಿ ಸಲಿಂಗ ಕಾಮವೆಂಬ ವ್ಯಾಧಿಗೂ ಸಲಹೆ, ಮಾರ್ಗದರ್ಶನ ಅಥವಾ ಇನ್ನಿತರ ಪರಿಹಾರಗಳನ್ನು ಕಂಡುಕೊಳ್ಳಲು ಏಕೆ ಪ್ರಯತ್ನಿಸಬಾರದು?

ಯಾವ ವಿದ್ಯಾವಂತ ವೃತ್ತ ಪತ್ರಿಕೆಯ ಅಂಕಣಕಾರ ಸಲಿಂಗಿಯರನ್ನು ರೋಗಿಗಳು ಅಂತ ಕರೀತಾರೆ?

ನೀವೇ ಹೇಳಿ? ಕನ್ನಡ ಪ್ರಭಕ್ಕೆ ಏನಾಗಿದೆ?
