Facebook Stat generation followup

Filed under: Computer Tips,Linux/Unix Related,My Thoughts,Techie Stuff — Suramya @ 2:16 AM

In my previous post I had talked about some of the stats I pulled from Facebook about it’s usage by my friends. This was an ad-hoc number crunching done just because I was bored and got curious. After the post went live a friend of mine, Ankush asked for more details on how I generated the numbers so in this post I am going to go over my process and how I got the numbers I shared.

Before we start, keep in mind that this is all data that is publicly available on FB, or at least shared with me. If you don’t want others to generate data about your activity on FB, you should change your privacy settings on FB and restrict access. Please don’t try to use this information to try to get access to data you are not supposed to. You will get in trouble and I will not take responsibility for it. Now that all that is out of the way, lets get to the details of the process.

The first thing you need is to have the Facebook Command Line client installed. Instructions on how to install are here so I am not going to repost them here. Make sure you authenticate the install and follow the steps in ‘Obtain Additional Authorization’ section of the installation guide otherwise the rest of the guide won’t be of much use to you.

Once you have FBCMD installed and configured, you can start playing with the options. Check out fbcmd Commands for the list of available options. You can also run the script with –help for the same.

/usr/bin/php /var/www/fbcmd/lib/fbcmd/fbcmd.php --help

Since I was interested in the photos uploaded the first command I ran was:

/usr/bin/php /var/www/fbcmd/lib/fbcmd/fbcmd.php OPICS =all FB_Pics

This command gets all the photos uploaded by folks in my friend list and downloaded them to the FB_Pics folder. As I mentioned in the previous post, this downloaded over 58k photos to my system. So be careful when you run it. You can also restrict it to a particular user by passing their name as a parameter.

To get the wall post count’s of all my friends, I ran the following command:

/usr/bin/php /var/www/fbcmd/lib/fbcmd/fbcmd.php FINFO wall_count =all

This gave me a output similar to the following:


NAME WALL_COUNT
Suramya Tomar 247
ABC 1405

I took this output, put it in an Excel file and did some analysis on it to get the max post count, least post count, Total count and top 10 user post counts. I could have done this using shell commands as well, but since this was a one time task I didn’t see the point. Maybe in the future I could set up a job that would do this periodically and do trending on the data but lets see. I don’t see much use for this data except for the coolness factor and to satisfy my curiosity.

Getting the birthday count was as easy as running the following command:

/usr/bin/php /var/www/fbcmd/lib/fbcmd/fbcmd.php FINFO birthday_date =all |wc -l

This returned the number of folks who had shared their birthday’s on FB and then I got the current location count using the following command:

/usr/bin/php /var/www/fbcmd/lib/fbcmd/fbcmd.php FINFO current_location =all |wc -l

So there you have it. This is how I generated the numbers I had posted earlier. As you can see there is nothing too complicated about it, so if you want you can generate similar stats for your friends as well.

Let me know if you have any questions and I will do my best to answer.

Well this is all for now. I should go and get some sleep now.

Some stats & numbers from my friends on Facebook

Filed under: My Life,My Thoughts,Techie Stuff — Suramya @ 1:54 AM

A few days ago I was trying to get a download of all the photos/events I was a part of from Facebook just so that I have a local copy of them. After looking around a bit I got the bright idea of using the Facebook Commandline interface that I was already using to sync the blog to the site. Instead of running it for only photos I was tagged in, I thought it would be easier if I ran it for all photos my friends had uploaded and then remove the ones where I am not there and events I wasn’t part of. I kicked it off at night before I went to sleep expecting it to have completed by the time I got up. The download ran for almost 36 hours and downloaded over 58,000 photos.

Keep in mind that these are all photos that I have access to on Facebook i.e. I can view the pic by clicking on the photogallery of the person that uploaded the photo. There might be more pics posted by these folks that I don’t have access to which are not accounted in this total.

The time it took to download it all wasn’t the most surprising part, that was for the number of photographs I downloaded. I have ~250 friends on Facebook and between all of them they have uploaded over 58k photos. Yes you read that correctly over 58,000 photos totaling about 4GB in size. Looking at the number of photos I just deleted all of them as I don’t have the time or energy to go through all of them searching for photos of me. I will at a later time kick off another download which will be restricted to only photos where I am tagged.

Once I got these numbers I got curious to see what other numbers I could get while looking at my friend circle. So I tried getting the number of wall posts that were made by friends. For some reason I only got results for 206 friends when I ran this query, which could be because of many reasons, most likely of which would be that these folks have blocked the access for the program to look that their post count, or they haven’t made any posts (which is highly unlikely). These 206 friends made a total of 89182 posts to Facebook with the highest no of posts being 3047 and the lowest being 4 with an average of 432.9. My post count is 207 in case you are wondering. 164 friends publicly shared their birthdays on FB and 187 of them posted their current location. (Not sure how accurate that is, but I did get GPS coordinates with the results…)

I am sure there is a lot more data I can pull out from FB, if I felt like it. But this is about as far as my desire to collect this data goes. I knew people posted a lot on FB but these numbers are way over what I thought the count would be…

Well this is all for now. Will post more later.

France bans managers from contacting workers outside business hours

Filed under: News/Articles — Suramya @ 11:58 AM

France because a very attractive place for employees yesterday when an agreement between employer organizations and labor unions in France has made it illegal for French managers to contact their employees about work-related matters outside of normal business hours. Think about it… if you were in France right now you could switch off your blackberry/email after 6pm and not worry about any work related items till next morning.

Although this is great news for workers, thinking about it from the employers perspective, it is not such a great ruling. What if a critical server went down at 7pm? Would you have to reach out to outsourced IT call centers for resolutions?

The agreement, which amends an existing pact signed in 1999, specifies that employees must have “the opportunity to disconnect from remote communication tools at their disposal” (in the words of Google’s Francophone translating robots) to ensure that they comply with strict rules on working hours.

That means French workers who receive emails or calls from coworkers or the boss at dinnertime can now safely ignore them without fear of retribution.

I bet a lot of folks are thinking about moving to France right about now…

Thanks to The Register for the story.

Blog/site is having issues

Filed under: Website Updates — Suramya @ 12:24 AM

The entire suramya.com domain is having issues, but the blog is the most hit. Spoke to 1and1 (my hosting provider) and as per them there is a issue ongoing that could be impacting my sites as well. They expect it to be resolved in the next day or so… As currently the blog admin pages are pretty much unusable so I don’t think I will be posting anything till it is resolved.

Update (2nd April 2014): The site is now back to normal, but still no answer on what was causing it to become so slow. Ah well… Atleast now I can get to the admin page now and all I need is some time to create posts.

Using E coli to build futuristic materials

Filed under: My Thoughts,News/Articles,Techie Stuff — Suramya @ 1:44 AM

Back in 2000 I had written an article for NJIT’s college newspaper ‘The Vector’ about how boffins at the University of Texas were using viruses to create semi-conductor chips. This weekend I was going through my files and I found a scanned copy of the article that I had been meaning to transcribe and post on the site but never got around doing, Then today I had a story about MIT researchers using Bacteria to assemble furniture pop-up in my feeds so I had to write a post about it. :)

Specifically, the MIT researchers were able to put bacteria to work producing conducting biofilms, some of which were studded with quantum dots, and arranging gold nanowires. This paves the way for the development of mass manufactured cell-based material factories, and even “living materials” that have some of the desirable properties of bones or trees, Lu confirmed.

They were able to do this by using E. coli, which naturally creates biofilms containing amyloid fibril proteins which, somewhat like the hooks in Velcro, help it attach to surfaces. The hooks on this gloopy velcro are made from a repeating chain of protein units called CsgA, which can be modified by adding peptides, which can be used to let parts of the film capture specific materials, like gold nanoparticles.

Basically the researches were able to make the bacteria grow in a particular design using a genetically engineered strain of CsgA, opening the way for future generations to be able to create bio-engineered equipment on demand. One of the things that is a bit scary is that they are using live bacteria for this experiment so they would have to be absolutely sure that they don’t mutate and cause a potential outbreak down the line.

I don’t know if this research is going to go anywhere or will it become another curiosity like the story on chip manufacture in 2000′s that never really went anywhere after the initial story. I did a cursory search today on that story but didn’t find any follow up articles or papers on it. Guess not every initial success is followed up by later successes and commercial successes.

Was a Keynote speaker at IndiaCom 2014: IEEE International Conference on Computing For Sustainable Global Development

Filed under: My Life — Suramya @ 1:25 AM

Early this month (Mar 7th) I was asked to give the keynote talk at INDIACom: 2014 IEEE International Conference on “Computing For Sustainable Global Development”. I gave my talk on Cloud Computing since it has been in the news a lot recently and there is a lot of interest in it from the general public. It was a pretty amazing experience and I had a lot of fun at the conference as I got to meet some pretty interesting folks with whom I discussed various things/technologies.

As the conference was in Delhi I had to fly there from Bangalore for the weekend and since I also wanted to avoid taking too many days off from work we decided to take a late flight to Delhi on Thursday night. Unfortunately though, our flight got delayed by an hour so instead of landing at 11:30am as expected we got there at 12:30am and by the time we got home it was almost 1:30am. Once home I did a bit more prep for the talk and crashed. Then I had to wake up early the next day to get ready so I could be there on time but thanks to traffic we got delayed and got there just about in time for the talk.

The funny part was that I was introduced as ‘Prof’ Suramya Tomar initially but thankfully they corrected it later. The talk went well and most of the questions I got during the talk were about how private the cloud is and how safe the data that is stored on the cloud is compared to traditional storage.

After the talk I sat through a few of the technical papers that were being presented and they were all pretty interesting. I did get a physical copy of the conference proceedings (a book about 1 1/2 inches thick) with all the papers that were presented that I am planning to read one of these days when I get some time.

One of the interesting things I noticed during the sessions was that about 60-70% of all the papers were authored/co-authored by women which is something that was very surprising to me as normally during such conferences the ratio is the other way round.

I am planning on transcribing my talk (I have my notes and the outline I created, plus a video of the talk) and posting it on the site sometime later this month/early next month. I will also expand on the talk with a few articles I am planning to write so keep an eye out for new items on the site (will announce it on the blog when I post stuff) in the near future.

Well this is all for now. Will write more later.

MIT wants you to Peel a Pine tree branch if you need a water filter

Filed under: Interesting Sites,Techie Stuff — Suramya @ 1:12 AM

Boffins at MIT have run some tests and found out that if you peel the bark off a Pine tree branch and pour water through the stick, then it will block upto 99% of e-coli bacteria and a host of other bad stuff giving up to four liters of drinkable water per day. This makes it a lot cheaper than any current commercial water filtration implementation in the market and a lot more scalable.

Dirty water is a major cause of mortality in the developing world. ‘The most common water-borne pathogens are bacteria (e.g. Escherichia coli, Salmonella typhi, Vibrio cholerae), viruses (e.g. adenoviruses, enteroviruses, hepatitis, rotavirus), and protozoa (e.g. giardia). These pathogens cause child mortality and also contribute to malnutrition and stunted growth of children.’ People have been working on engineering cheaper and cheaper filtration systems for years, but now a group of researchers has found a promising and simple solution: a tree branch. ‘Approximately 3 cm^3 of sapwood can filter water at the rate of several liters per day, sufficient to meet the clean drinking water needs of one person.’

Of course there are some caveats; the system can trap most types of bacteria, the smallest of which measure about 200 nanometers but currently cannot trap viruses most of which are much smaller in size. Also, the stick needs to be kept wet or the filtration is not that effective.

The researchers have published a paper in this week’s journal PLoS ONE where they go over their findings and demo this functionality. Check it out if you have some time.

I am definitely adding this to my things to know in case of an emergency list. :)

Thanks to Slashdot for the initial story.

Beard transplant business is booming in New York thanks to Hipsters

Filed under: Humor — Suramya @ 2:07 AM

Do you aspire to look like a homeless guy but don’t have the facial hair to pull of the look? If so fear not, NY Cosmetic surgeons are willing to help you for a mere $8,000. Hipsters all around the world rejoice!

Facial surgeons with private practices in Manhattan and Florida say they have seen a phenomenal increase in demand in the last five years, and hipsters are leading the way.

No longer the preserve of fishermen or aging academics, beards are the signature look of urbane men in their 20s and 30s who consider themselves witty, creative and politically progressive.

New York surgeons can perform up to three or four procedures a week for $2,000 to more than $8,000 depending on how much hair needs to be transplanted from scalp to cheek.

When I first saw this article I thought it was a joke which got accidentally released early for April fool’s day. But unfortunately this is true and that tells us something about these people. They are willing to pay ridiculous amounts of money for stupid stuff like this but won’t spare change for an actual homeless guy. If you really want to feel what the homeless feel, try living for a week on the street without your Starbucks or iPad’s.

The no of people asking for this procedure have gone up from 10 a YEAR to 5 a WEEK. Yikes!

Thanks to The Register for the initial story.

My RaspberryPi Camera module finally arrived and it works great!

Filed under: Computer Hardware,Linux/Unix Related,My Thoughts,Techie Stuff — Suramya @ 2:06 AM

After months of waiting (about 2 to be exact) my RaspberryPi Camera module finally arrived today and I took it for a brief spin. Setting it up was really easy, I just installed the Rasbian image I have, updated the install to the latest version and then enabled the camera. Once that was done and I rebooted the Pi, the camera started working without any issues. The instructions I followed are at: RaspberryPi Camera.

As part of the test I got the pi to transmit the images to my desktop and the clarity was pretty good, there was a slight lag in the display of about 1/2 a second but at 1080p I don’t think I can complain. Below are some pics I took of the setup and of the image being streamed to my desktop.


The Camera module next to my keyboard for a size comparison


Photo of my hand being streamed live to my desktop from the Pi.

I do plan to take pics using the camera module itself, but there is nothing interesting on my desk that I wanted to take photos of so you will have to wait for a day or two and I will take pics of the view from my window and post.

Well this is all for now, I should go get some sleep now considering I have an early start tomorrow.

Great Insults from Science Fiction and Fantasy Books

Filed under: Books Related,Humor,My Thoughts — Suramya @ 10:45 PM

Are you tired of using the same old insults for people who annoy you? Are you tired of using the same insults as everyone else? I know I am, but worry not, the great’s of Science Fiction and Fantasy novels have your back with some really cool insults that you can use without actually abusing. Folks at io9 spent some time to generate a list of 20 best insults and it has some gems. Below are some examples that I especially liked:

3) Timequake by Kurt Vonnegut

“If your brains were dynamite there wouldn’t be enough to blow your hat off.”

5) Mort by Terry Pratchett

“‘It would seem that you have no useful skill or talent whatsoever,’ he said. ‘Have you thought of going into teaching?’”
6) Redwall by Brian Jacques

“To describe the young haremaid’s singing voice as akin to a frog trapped beneath a hot stone would have been a great insult to both frog and stone.”

Check out the whole list at 20 Great Insults from Science Fiction and Fantasy Books

Maybe I should start using these more often. :)
