Apparently knives manufactured from frozen human feces do not work to no one’s surprise

Filed under: Interesting Sites,My Thoughts — Suramya @ 1:58 PM

Let me start this by saying Eww Gross. I have no idea why someone would decide to make a knife out of their own shit but apparently that’s a popular trope in literature. The story goes something like this:

“There is a well known account of an old Inuit man who refused to move into a settlement. Over the objections of his family, he made plans to stay on the ice. To stop him, they took away all of his tools. So in the midst of a winter gale, he stepped out of their igloo, defecated, and honed the feces into a frozen blade, which he sharpened with a spray of saliva. With the knife he killed a dog. Using its rib cage as a sled and its hide to harness another dog, he disappeared into the darkness.”

So a whole bunch of researchers decided to test this story out and basically spent a lot of time freezing crap and then trying to cut things with it. I am really happy that I work with software and if/when I meet any of the scientists in this study I don’t think I will be shaking hands with them 😉 (Yeah, yeah… I know that they don’t touch the stuff with their bare hands but still). Though it is apparently possible though to use frozen feces as a chisel though as shown by the memoir of Peter Freuchen, the Danish arctic explorer. When he was trapped in snow in a pit and unable to get out he used his frozen excrement to make a chisel and get out:

Freuchen (1953) describes how he dug himself a pit to sleep in and woke up trapped by snow. Every effort to get out that he tried failed. Finally, he recalled seeing dog’s excrement frozen solid as a rock. So, Freuchen defecated in his hand, shaped it into a chisel, and waited for it to freeze solid. He then used the implement to free himself from the snow: “I moved my bowels and from the excrement I managed to fashion a chisel-like instrument which I left to freeze… At last I decided to try my chisel and it worked” .

While living off the land with no tools is good and all I would recommend that you try some other ways of making a knife if you actually want to survive instead of freezing your excrement.

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

Thoughts on Chandrayaan-2

Filed under: My Thoughts — Suramya @ 12:48 PM

Last Saturday, 7th Sept the entire world was watching with bated breath for Chandrayaan 2 to make its final approach and attempt a soft landing at the Moon’s south pole. This was the first time that I remember where even the lay person knew about this attempt and everyone was eagerly waiting for the landing. In this post I am going to talk about the project, people’s reaction to it, and my thoughts. As always all thoughts are mine and not my employer’s. Also, the idea is not to offend/argue with people but to talk about my thoughts on the project and evolution of our space program and some commentary on the reactions to the attempt that we saw.

ISRO was founded in 1969 and put its first satellite, Aryabhata in orbit in 1975. After that over the years things started speeding up at ISRO but it was hardly ever in the public eye. In 2008 ISRO sent a lunar orbiter, Chandrayaan-1 to the moon which was the first probe to discover the presence of water in the form of ice on the Moon. However I don’t remember reading or hearing anything about it in the Media.I only found out about the fact that it was the first one to detect water on the moon when I was researching about Chandrayaan 2. There was minimal coverage for the achievement and ISRO continued chugging along without making waves. When it’s Mangalyaan achieved Mars orbit in 2014 making India the first Asian country to reach Mars the Indian media’s reaction was again quite muted. There were a few articles in the papers and minor coverage on TV. International media was also quite dismissive with several articles making fun of the achievement and asking why India was bothering to pay for a Mars mission when people were starving in the country. Over the decades we have gone from hitching rides in foreign rockets to launching 104 satellites on a single rocket on 15 February 2017 which was a world record and it still stands. This makes India the prime choice for countries wanting to put satellites in orbit bringing much needed foreign currency/business to India. Even in 2017 there was some coverage of the achievement but mostly in specialized sites focused on Space etc and not so much in the traditional media. My sis Surabhi and her family went to Sri Harikota to watch the launch and getting the information on how to watch the launch in person was a painful process and required us to find personal contact in ISRO to get permission.

Now in 2019, the situation is so much different that its like night and day, the process is very different and there is an actual observation gallery at ISRO launch site and people are encouraged to watch launches. (I was actually planning on going in person for Chandrayaan 2 launch but was traveling during the launch and couldn’t make it). During the runup to the launch I saw multiple posts about it in social media, in the newspapers and on TV. The launch was carried live on multiple TV channels and there was a dedicated media campaign to publicize the launch. ISRO and the government used this opportunity to get school children excited about space and show them the possibilities. I watched the launch live on Twitter in office and when the rocket took off successfully the mood was quite celebratory. Even on social media you could see the outpouring of love and pride in ISRO and India during and after the launch.

On Saturday when Chandrayaan 2 was supposed to attempt a landing it was late at night but almost everyone I knew was awake and watching this historic attempt. My 7 year old Nephew and 4 year old niece was amongst the watches as well even though it was way past their bed time. Vinit took a pic of them watching and you can see how sleepy they both are but still refusing to go to sleep.

Unfortunately in the last mile (2.1kms) above the surface ISRO lost contact with the lander and we could see how tense and worried the staff at mission control was and how professionally they tried everything possible to reestablish contact. The anchor on National Geographic (sorry can’t remember his name) was almost in tears when we realized that there was a high probability that the attempt had failed.

ISRO chief K Sivan was understandably choked up when he made the formal announcement “This is Mission Control Centre. Vikram Lander descent was as planned and normal performance was observed up to an altitude of 2.1 km. Subsequently, communication from lander to the ground stations was lost. Data is being analyzed.”. PM Modi was there on site for the landing and he consoled the scientists saying “Don’t lose hope. Be courageous”. The next morning at 8am PM Modi was back at ISRO and commended the scientists at ISRO and was positive & supportive in his speech (extracts below):

“Friends I could feel what you were going through a few hours back, your eyes were conveying a lot. You live for India’s honour, I salute you”
“To our scientists, I want to say India is with you. Your hard work and efforts ensure a better life for citizens and nation. It was your zeal that several people had access to a better life, better education and health facilities. There will be more opportunities to rejoice and pride”.
“You are exceptional professionals who have made an incredible contribution to national progress. You have always given your best. We will give you several more opportunities to smile,”

At this point K Sivan broke down in tears and PM Modi can be seen hugging and consoling Sivan in a now viral video/photo. Across the globe people commended his action and noted that his hug was on behalf of a grateful nation.

Unfortunately, we have people in the world who believe in toxic masculinity and think that any display of emotion by a guy is shameful. This was the view of Gaurav Pandhi who posted:

I know. A person who can’t control his/her emotions and cries at the time of crisis can’t be fit to lead a team; more so for someone who is heading ISRO, India’s premier space agency.
— Gaurav Pandhi गौरव पांधी (@GauravPandhi) September 7, 2019

I was expecting better temperament from the @ISRO chairman. Failures happen and are stepping stones for the success ahead. ISRO’s achievements and efforts are applauded by the entire world. A man of his stature crying like a baby because of shortfalls looks idiotic to me.
— Gaurav Pandhi गौरव पांधी (@GauravPandhi) September 7, 2019

Sivan was the consummate professional while the crises was going on, he coordinated with all the relevant parties to reestablish contact and only after it was clear that nothing else could be done immediately he allowed his heartbreak to show and gave in to tears. When you spend a decade of your life on a project and invest your heart and soul into it, its quite natural to want to cry when faced with failure. If he had started crying during the crises and not worked to resolve it, I would have felt differently but in this case he worked through his heartbreak and then broke down after the immediate crises was over. I feel sad that people still think that its unmanly to cry. It is a stupid stereotype that causes a lot of harm.

But I am happy to state that the internet didn’t take kindly to Gaurav’s statement and immediately people (both men and women) posted messages supporting Sivan and condemning Gaurav’s statement. I haven’t checked if he recanted but I doubt that it would happen. (Please correct me if I am wrong here). Majority of India and the world also supported ISRO during this time and posts/comments commending the effort and praising the scientists poured in from all over the world. The general attitude was that yes we failed this time but will be back stronger than ever and succeed in our next attempt. It would have been great if the same was true for our political leaders but that wasn’t the case and case in point is Mamta Banerjee, who couldn’t resist bringing politics into the picture and said in a statement:

“It is as if Chandrayaan launch is the first such happening in the country. As if before they came to power, no such missions were taken up. It is an attempt to divert attention from the economic disaster,”

Thankfully, she is in the minority and most political leaders read the nation’s mood correctly and are supportive in public. The twitter trolls also couldn’t resist pitching in either and I saw a few posts to the effect that Modi was only there to take credit and blah blah blah. One comment that caught my eye just because of the sheer nonsense in it, was from someone named Atul who posted:

@atul_aga: He came to take credit.
He was informed that Vikam’s landing is failed.
Got annoyed and returned to his hotel.
Next morning again he returns with his camera crew to do theatrics to steal the show.
Many so called liberals melted for his drama.
Mission successful.

If Modi attended the launch it was to take credit, if he hadn’t then it was because he was not giving the ISRO folks enough importance. If he went back to his hotel it was because he was annoyed, never mind the fact that there was nothing for him to do at that time. ISRO was still working on reestablishing contact, all sitting there in the mission control would have accomplished would have been to put extra pressure on the folks trying to work. When he consoled the ISRO staff, promised support for the next attempt and told them how proud the nation was of their effort it was a “PR stunt”. Just because historically Indian politicians have not been around or supportive when their nation take a literal moon-shot doesn’t mean that we pull down the one person who made the effort. If you think this is grandstanding, please look up videos of Obama, Nixon, and other world leaders who were with the staff when they attempted to reach the impossible and supported them when they faltered.

Bringing politics into this is shameful, this was something that India did and as someone commented, “India is the brain behind the mission but it is on behalf of all humans”. We need to come out of our cocoon and look at a world outside of politics and pulling Modi down.

In any case, as of today it looks like Vikram survived the landing and is in one piece. But we still don’t have connectivity with the lander and efforts are ongoing to reestablish contact. Even if we don’t the orbiter is still functional and 95% of the experiments planned for the mission are aboard the orbiter and will proceed as planned.

In conclusion, I am happy how the general public is supporting ISRO in this time and how many people are getting motivated to go into science or space after watching this historic attempt. Hoping for the best here’s to ISRO, the nation salutes you.

Criminals use AI technology to impersonate CEO for a $243,000 payday

Filed under: Computer Security,My Thoughts,Techie Stuff — Suramya @ 10:46 AM

Over the past few years AI has become one of the things that is included in everything from cars to lights whether it makes sense or not and criminals are not behind in this trend. We have AI based systems testing computer security, working on bypassing checks and balances in systems etc and now in a new twist, AI is being used in Vishing as well. Voice phishing or vishing as it’s sometime referred to is a form of criminal phone fraud, using social engineering over the telephone system to gain access to private personal and financial information for the purpose of financial reward.

Anatomy of Vishing Attack
Anatomy of Vishing Attack. Source: https://www.biocatch.com/blog/detect-vishing-voice-phishing

In this particular instance criminals used commercially available voice-generating AI software to impersonate the CEO of a German Company and then convinced the CEO of their UK based subsidiary to transfer $243,000 to a Hungarian supplier. The AI was able to mimic the voice almost perfectly including his slight German accent and voice patterns. This is a new phase of crime and unfortunately will not be a one-off case as criminals will soon realize the potential then these kind of attacks are only bound to increase in frequency. Interestingly it will also make the biometric voice authentication systems used by certain banks like Citibank more vulnerable to fraud.

To safeguard from the economic and reputational fallout, it’s crucial that all instructions are verified via a follow-up email or other alternative means i.e. if you have an email asking for a transfer/detail call the person and if you get a call asking for transfer follow up via email or other means. Do not use a number provided by the call for verification, you need to call the number in the company address-book or in your records.

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

RIP: Terrance Dicks – One of the most influential writers in Doctor Who dies age 84

Filed under: My Thoughts — Suramya @ 1:13 PM

Those of you who know me personally know that I am a big fan of Doctor Who. I first came in contact with Dr Who through the novelizations of their TV episodes by Target and one of the most prolific writers of the novelizations was Terrance Dicks, he wrote more than 60 of the 156 books published. In addition he also edited or wrote over 150 episodes of Dr Who making him an important influencer of the programs mythos so I consider him one of my all time favorite authors. So it was a shock to come home after a road trip and find out that Terrance Dicks died last Thursday 29th August after a short illness at the age of 84.

My favorite quote by Dicks is the following:

“No point in being a grown-up if you can’t be childish.”
― Terrance Dicks, Doctor Who and the Giant Robot

RIP Terrance Dicks, you shall be missed.

AI Emotion-Detection Arms Race starts with AI created to mask emotions

Filed under: Computer Software,My Thoughts — Suramya @ 2:31 PM

Over the past few months/years we have been reading a lot about AI being used to identify emotions like fear, confusion and even traits like lying or trustworthiness of a person by analyzing video & audio recordings. This is driving innovations in Recruiting, Criminal investigations etc. In fact the global emotion detection and recognition market is estimated to witness a compound annual growth rate of 32.7% between 2018 – 2023, driving the market to reach USD 24.74 billion by 2020. So a lot of companies are focusing their efforts in this space as AI applications that are emotionally aware give a more realistic experience for users. However, there are multiple privacy implications of having a system detect a person’s emotional state when interacting with an online system.

So to counter this trend of systems becoming more and more aware there is now a group of researchers who have come up with an AI-based countermeasure to mask emotion in spoken words, kicking off an arms race between the two factions. The idea is to automatically converting emotional speech into “normal” speech using AI.

Their method for masking emotion involves collecting speech, analyzing it, and extracting emotional features from the raw signal. Next, an AI program trains on this signal and replaces the emotional indicators in speech, flattening them. Finally, a voice synthesizer re-generates the normalized speech using the AIs outputs, which gets sent to the cloud. The researchers say that this method reduced emotional identification by 96 percent in an experiment, although speech recognition accuracy decreased, with a word error rate of 35 percent.

In a way its quite cool because it removes a potential privacy issue, but if you extrapolate from existing research then we have the potential of bigger headaches in the future. Currently we have the capability of removing emotion from a audio recording, how difficult would it be to add emotion to a recording? Not too difficult if you go through the ongoing research. So, now we have a system that can take a audio/video recording and change the emotion from sadness to mocking or from happy to sad. This combined with the deepfakes apps that are already there in the market will cause huge headaches for the public as it would be really hard for us to determine if a given audio/video is authentic or altered.

LinuxJournal.com: shutdown -h now

Filed under: Computer Related,My Thoughts,Techie Stuff — Suramya @ 10:24 AM

Last week I got an unpleasant surprise in my mailbox, an email from Linux Journal stating that they were closing up shop effective immediately as they had completely run out of money with no hope of resurrection. LJ was one of the first Linux magazines I wrote for and it will always have a special place in my heart.

IMPORTANT NOTICE FROM LINUX JOURNAL, LLC:
On August 7, 2019, Linux Journal shut its doors for good. All staff were laid off and the company is left with no operating funds to continue in any capacity. The website will continue to stay up for the next few weeks, hopefully longer for archival purposes if we can make it happen.
–Linux Journal, LLC

The website is up for the moment but might go down anytime. I do have an archive of all LJ issues on my home computer that I had made the last time LJ was about to shutdown and I will post them to the site in a few days. This archive doesn’t have the latest releases so I will need to download that before I post them online. In addition I am sure there are efforts ongoing to archive the website as well since it had a lot of great content on it. If not then I will kick off something to archive the site once I get home.

Well this is all for now. It was a great run LJ, you will be missed.

Using a slice of wood to make saltwater drinkable

Filed under: My Thoughts,Techie Stuff — Suramya @ 5:45 PM

“Water water everywhere, not a drop to drink” This is an often quoted line from The Rime of the Ancient Mariner by Samuel Taylor Coleridge and is something that is becoming more and more true every day. 71% of earth is covered by Oceans but we still have 2.8 billion people around the world who face water scarcity at least one month out of every year. Earlier this year city officials in Chennai, India declared that “Day Zero” (the day when almost no water is left in the city) had been reached in Chennai, as all the four main reservoirs supplying water to the city had run dry due to deficient monsoon rainfall in the previous years. Due to this finding more ways of generating drinking water a high priority for the Human race. Without water life as we know it can’t exist and our civilization can and will collapse.

One of the ways to solve this issue is to convert sea water to drinkable water by filtering the salt out and there are existing solutions which do this (check out the Saudi water desalination) but they require a lot of energy and/or specialized engineering. But this is about to change thanks to the effort of Jason Ren and his colleagues from Princeton University in New Jersey. They have developed a method that uses a new kind of membrane made of American basswood instead of plastic that enables filtration without requiring high pressure pumping of salt water. Basically they took a thin slice of American basswood and treated it with a chemical bath to remove extra fibers from the wood and make its surface slippery to water molecules. Once the wood is treated water flows down one side of the membrane and is heated to the point that it vaporizes. The vapor then travels through the pores in the membrane toward its colder side leaving the salt behind, condensing as fresh, cool water.

This process takes less energy than simply boiling all of the saltwater because there’s no need to maintain a high temperature for more than a thin layer of water at a time as per Jason Ren. In the initial testing using this method the team was able to filter about 20 kilograms of water per square metre of membrane per hour, which is not quite as quick as polymer membranes but this can improve if the membrane is made thinner.

This is quite a breakthrough and when I first read the article I was not clear why we need to use wood for the process. I mean we can use a polymer membrane and still achieve the same effect by heating only a thin layer of water at a time. But then I spent some time reading the actual research paper and that’s when I realized what a massive breakthrough this was. Basically the current commercial MD membranes have porosity lower than 0.80, thermal conductivity higher than 0.050 W m−1 K−1, and thermal efficiency up to 60% where as the new membrane has a porosity of ~90%, low thermal conductivity (~0.04 W m−1 K−1) and a thermal efficiency of ~71%. These factors combined reduce the energy requirements for desalination by a significant amount.

Now that we have a Proof of Concept that this works, we need to be able to scale this up on a massive scale and work for this is currently ongoing.

Our Trip to Dandeli

Filed under: My Life,My Thoughts,Travel/Trips — Suramya @ 11:24 PM

Last weekend we booked an adventure tour to Dandeli and it was ‘interesting’ in the Chinese curse sense of the word. Normally when I blog about trips I tend to avoid posting about the bad parts of the trip in detail since we usually end up having a lot of fun and can ignore the bad parts. However in this case I will be posting all the ‘fun’ things that happened to us during the trip. This trip was booked through Thrillophilia for 7 people and was another bad experience with them. (I actually didn’t post about the last trip as I was annoyed enough by the trip to decide it was better to not write anything). The booking was done on-line and we got a confirmation email a day later with a map location for the resort. I did notice that the name of the venue wasn’t listed on the email (It only said ‘Dandeli tours’) but paid it no attention at the time.

We left from Bangalore around 11pm due to traffic and the drive was long… It took us ~14 hours to reach the location shared with us as it was raining and we couldn’t drive fast. When we finally reached the map location we found that the location shared was for Dewdrops adventure tours and they were quite helpful in trying to help us figure out where we were supposed to go. Since we didn’t know the name of the place we couldn’t get accurate directions. There was a number shared in the email and we finally managed to get through to it after multiple attempts as the connectivity was quite bad in the area. That’s when we figured out that our booking was for Panther and had to drive another 2 kms to get to the venue. After driving 14 hours to get to the place it was not a great start to the experience. Unfortunately things only got worse as we continued.

The last mile road to Panther was quite bad and our TT actually got stuck in the mud once while getting there. Thankfully our driver was quite good and we managed to get unstuck and arrived at the venue. At a first look the venue looked nice and we walked over to the reception to check in. When we tried to check in, Mr Veeresh, the person in charge tells us that we were booked for tents even though we had paid for 3 cottages at a twin sharing basis (with an extra bed in 1 cottage) and we had received the confirmation for the same. As per him they had gotten a request for tents and not rooms. After showing him the confirmation email he told us to hold on and disappeared for almost 30 mins. Finally he came back and gave 2 cottages on a 4 person sharing basis as that was the only option available. We didn’t want to take tents as it was raining quite heavily and wanted to avoid the joy of common showers/toilets. Since no other options were available we had to take the rooms offered and checked in. He did tell us that we should reach out to Thrillophilla for the refund (as the twin sharing rooms were more expensive).

Once we got the rooms, we dumped our luggage in there and since we had been travelling all night and had a very light breakfast we were all quite hungry and it was another 1 ½ hours before lunch would be served. So we walked over to the dining area and asked them for some snacks before lunch. We were told that they can’t serve us anything and we would have to wait till lunch was served. Even when we offered to pay they refused us point blank. With no other option we had to dig in to our snacks bag and try to survive on Chips/nuts etc.

We all freshened up and rested for a bit while we waited for lunch to be served. After lunch we decided to get in the water and Canoe in the Pool. So we all changed and walked over to the area. Thankfully the pool (?) was empty at the time and we got the entire place to ourselves. Jani refused to enter the water as she wasn’t comfortable with the other people staying at the place (more on this later) and the fact that the water was filthy.


Kayaking at the Venue


Kayaking at the Venue

The kayaking venue had algae floating it in and filled with frogs and other insects/creepy crawlers and it didn’t look like it had been cleaned this year. But since we weren’t planning on taking a dip in the water we got in the boats and fooled around in the water for a bit. But we couldn’t stay in there for long as the water was filthy and we didn’t want to risk an infection by staying in it longer than required. So we got out and decided to try out the rain shower. Unfortunately, the rain shower setup was taking the filthy water from the kayaking place and showering it on the people. The floor of the shower was caked in algae and I couldn’t stay in the water for long. So we immediately got out and decided to try out the pool which was a different setup and we hoped that it would be cleaner. We were disappointed when we reached the ‘Pool’. It wasn’t actually a pool, it was a big tub masquerading as a pool which had water which was so dirty with mud, dead insects, algae and filth in it. I don’t think it had been cleaned anytime in the near past. Since we had entered the water we needed to take a bath in Dettol (Thankfully we carried it with us) water to disinfect us after entering this unclean water.

By this time it was around 3:30-4pm and since the weather was amazing we decided to get some tea and just hang out. So we asked for tea and were told that nothing is available and tea will be only served at 5:30pm. Which is bizarre behavior, but with no other option we had to wait. When the tea was finally served it was served without any snacks as snacks are only served starting at 7:30pm. Is this a college canteen or PG accommodation we were staying at? I have travelled extensively and this is the first place where people are refusing to serve food even when you offer to pay for it when they have a working kitchen. In our last trip the place we stayed didn’t have an attached kitchen but they still served us tea and snacks when we asked.

So we had our tea without pakoda’s and then played a little carrom and badminton to kill time. We did manage to do the Zipline and Burma bridge and thankfully both were decent and nothing broke which was a pleasant surprise considering the state of the rest of the place..
By now we noticed that there appeared to be only three girls in the entire camp and the rest were a bunch of very rowdy guys who spent majority of the time drinking and creating a ruckus. As we didn’t want to interact with them and there weren’t any other options available to pass the time we retreated to the room and passed the time playing cards, and uno. Both were a lot of fun since we had a great group of people with us. If we had come here alone we wouldn’t have enjoyed it at all.


Group photo at the Room

Later in the evening a campfire was organized even though the wood was quite wet and it was a valiant effort. They also played some music so the bunch of us decided to turn the dining area into an impromptu dance floor. The dances were hilarious and no I am not going to share the videos that Jani took. After a while the other groups joined us in the dancing and that’s when we stopped for dinner as they were just weird. We had dinner and then headed back to the room and played some more cards and Jenga since we couldn’t step out to go somewhere else due to the constant rain.

It was Akanksha’s birthday so at midnight we cut a cupcake to celebrate the event. We couldn’t get a cake as it would have spoilt if we had carried it from home and there was no place near the venue to get it. After the cake cutting we walked around a bit inside the property but had to quickly comeback to the room as the guys I spoke about earlier started creepily staring at the girls.


Cupcake cutting at midnight

Next morning we (me and Jani) slept late while the rest of the group went for a Jungle safari. Apparently the drive was through some amazing scenery but they didn’t see any wild animals except the usual deer etc. Interestingly the only way to get to the jungle safari place was using your own vehicle. I was expecting the venue to provide transportation to the place but I guess that was too much hospitality to expect. After the safari we had breakfast and started the long drive back. We picked up a cake on the way and properly had the cake cutting. The cake was fine although the grated coconut on a black forest cake was a bit surprising. We reached home after about 12 hours of driving and by then all of us were exhausted and basically crashed.


Cake Cutting at Kamath

The over all trip was fun because we had a good group but the venue was not at all worth the money we spent on it and we were quite disappointed with our experience.

We have reached out to Thrillophilla and complained about the experience. They are looking into it and will get back to us once their investigation is complete. Depending on how that goes we will see if we want to ever book with them again as this was the 2nd or 3rd time with these guys with a bad experience everytime.
Well this is all for now. Will write more later.

Someone has made a Hurricane Proof House from Recycled Plastic

Filed under: Interesting Sites,My Thoughts — Suramya @ 4:44 PM

Plastic is one of the most popular material for making things and is extremely popular. However there are some significant disadvantages of Plastic that are becoming more and more apparent due to the focus on environment and climate change. Some biggest disadvantages of Plastic are as follows

  • Durability: Plastic is light, mold able, sturdy, and can have countless forms, but one of the most known features is its durability. Plastic can survive for many centuries before nature is able to degrade it
  • Environmental Harm: Since Plastic takes a long time to degrade it continues to clog our waterways, oceans, forests, and other natural habitats. These are consumed by animals who mistake them for food and then die. Recently 9 deer were found dead in a famed park in western Japan after eating plastic bags
  • Choking Hazard: Plastic is one of the most popular building materials for small items. These toys and small plastic objects of many uses can easily get into children’s hands (especially babies and toddlers) that unknowingly put them in their mouth.

So what do we do about it? Banning it is not a great idea till we have replacement options available. For example plastic straws are banned in a lot of places but paper straws don’t last long enough to be useful.

A Canadian company called JD Composites has a potential solution to the problem. They have created a process where they took about 612,000 plastic bottles and shred them. The result is then melted and injected with gas to create a plastic based foam. This foam is them shaped into 5.9 inch thick panels which are then used in house construction. Based on the testing done at a certification facility these panels can withstand winds of over 300 miles per hour (hurricane strength) and as an added bonus they also provide better insulation. If the process becomes mainstream it will keep a large no of bottles (and plastic) out of landfills. While this is a positive step there are still a lot of certifications/studies etc that would need to be done on the process to ensure there are no unexpected side-affects from the process. We don’t want to be in a situation like we were with asbestos where we found out that it causes cancer a few decades after it was put in a large no of homes & offices as insulation.

A sample three bedroom home was created near the Meteghan River in Nova Scotia and is actually up for sale right now. If the builders are unable to find a buyer they are planning to list it on Airbnb and see if that creates enough buzz about the process for it to become mainstream. I hope that this process becomes mainstream quickly so that we can reduce the amount of crap we are putting in the garbage.

Chandrayaan-2: ISRO spacecraft successfully achieves Geostationary Orbit

Filed under: My Thoughts,Techie Stuff — Suramya @ 3:55 PM

ISRO’s Chandrayaan-2 completed the first stage of the Moon mission by successfully entering Geostationary Orbit at 181.65 km above sea level. This is an amazing achievement by ISRO and is a proud moment for India. After the last min abort of the previous launch attempt all eyes were on ISRO to make a successful launch in a extremely tight launch window of only a few minutes. ISRO Chief K Sivan, made the following statement after the launch

I’m extremely happy to announce that the GSLVMkIII-M1 successfully injected Chandrayaan-2 spacecraft into Earth Orbit. It is the beginning of a historic journey of India towards moon and to land at a place near South Pole to carry out scientific experiments:

Now that the rocket has achieved Geo-Stationary orbit it will start orbit-raising operations followed by trans-lunar injection using its own power. Post that the rocket will head out to the Moon and below are the different phases of Chandrayaan 2’s journey:

  • July 22 to August 13: Chandrayaan 2 will orbit around the Earth in an elliptical path
  • August 13 to August 19: Course change to to establish into moon’s orbit
  • August 19: Enter Moon’s orbit
  • August 19 to Aug 31: Chandrayaan 2 will revolve in the Moon’s orbit
  • September 1: The Lander Vikram will detach from the Orbiter heading down to land near the South Pole of the Moon
  • ~September 7:Lander Vikram will make a soft landing in the south polar region of the moon
  • ~Landing + 4hours: Rover Pragyaan will roll out of the Lander Vikram and perform different tests on the Moon’s polar surface

@ISRO, a proud nation salutes you and here’s to the journey to new horizons.
