ISRO completes the first Integrated Air Drop Test for Gaganyaan Missions successfully

Filed under: Astronomy / Space,My Thoughts,Science Related — Suramya @ 11:59 PM

India’s space program has been very active over the past few years and following the success of Chandrayaan-3 & Aditya missions, India became the 4th nation to dock two satellites in space earlier this month. The next major mission ISRO is planning is the Gaganyaan mission. Gaganyaan (“Orbital Vehicle”) is a crewed orbital spacecraft intended to be the basis of the Indian Human Spaceflight Programme. The first of three flight tests prior to the inaugural of crewed mission is planned for December 2025. But before that there are multiple tests & launches planned for testing the equipment and earlier this week, ISRO successfully completed its first Integrated Air Drop Test for Gaganyaan Missions. An air drop test recreates the final leg of a spacecraft’s journey back to Earth by dropping the spacecraft from a height to test various systems under different circumstances.

In Gaganyaan missions, parachute-based Deceleration system is employed during terminal phase of Crew Module (CM) descent to reduce the touchdown velocity of Crew Module to an acceptable limit for safe landing on sea. The parachute system and its layout, for IADT, was same as that of Gaganyaan missions. It comprised of four types of parachutes viz. Apex Cover Separation (ACS) (Ø 2.5 m – 2 nos), Drogue (Ø5.8 m – 2nos), Pilot (Ø3.4 m – 3 nos.) and Main parachutes (Ø 25 m – 3nos.).

In IADT-01, the simulated Crew module (~4.8 t) with Parachute system was released from an altitude of about 3 km using Indian Air Force’s Chinook Heavy lift helicopter. The deceleration system initiation began with firing of ACS Mortar which deploys the Ø2.5 m ACS parachutes, which is followed by the separation of Apex cover. The deployed ACS parachutes then decelerated the Apex cover and prevented it from re-contacting the descending simulated CM during the test. The Ø5.8 m Drogue parachutes were then deployed using Drogue Mortar, which provided first stage deceleration to the simulated crew module. After first stage deceleration, the Drogue parachutes were released using pyro-based parachute releasers. This was followed by firing of three Pilot Mortars, which ejected and deployed the Ø3.4 m Pilot parachutes., which then independently extracted and deployed the three Main parachutes of Ø25 m diameter.

Now that we have successfully cleared the first integrated drop test, work on the second test mission in the third quarter of 2025 is moving at a fast pace. This second test will simulate an abort scenario to demo the crew escape system for the Gaganyaan. After this, in Q4 2025 the first uncrewed mission Gaganyaan-1 will take place, which will carry an unpressurised crew module to space and back. Two more uncrewed test flights are planned in early 2026 for additional testing of equipment which will be followed by a crewed mission in Q3/Q4 2026.

Looking forward to more successful missions by ISRO.

By extrapolating statements by prominent AI proponents it looks like the AI bubble might be nearing its end

Filed under: Artificial Intelligence,My Thoughts — Suramya @ 1:33 AM

We are in the middle of an almost unprecedented tech-bubble for AI and now it looks like the bubble is nearing it end. The reason I say that is now instead of companies trying to sell us AI as the cure all for everything we have reports coming out with stories that are strikingly different in tone from the ones a few days ago.

For example, Sam Altman is now telling people that the “investors are overexcited about AI models. ‘Someone’ will lose a “phenomenal amount of money.”. The head of Amazon Web Services Matt Garman is now telling folks that “Laying off engineers for AI is the dumbest thing companies are doing”. Then we have the report from MIT that states that 95% of generative AI pilots at companies are failing.

There are multiple such stories that are now coming out now and it feels like a push towards gaslighting the world about how the same people were not the ones who pushed AI as a cure all and replacement for the humans in pretty much every industry and aspects of our lives. AI systems were nowhere close to what the hucksters were claiming to be possible and in a lot of cases we found out that the demo’s were faked with developers in the background doing the actual work.

The impact of this burst is going to be brutal especially in the Tech Company side as they moved away from their core competencies and crammed ‘AI’ into their products regardless of whether folks wanted it or not. That being said, not all is bad because once the hype machine dies, people who have been actually working on interesting AI or Machine learning models will emerge from the shadows of the hype and we should see some good progress down the line. This is similar to what happened during the DotCom collapse (I caught the tail end of that during college) where the companies that were built on hype & lies collapsed but the infra created from them was absorbed by others who had actual useful products.

Lets see how things go from here… At the very least we should soon start seeing more and more people getting hired to fix the code created by the vibe-coders.

Building an app that no one uses is useless

Filed under: My Thoughts,Tech Related — Suramya @ 11:27 AM

A quote that all of us have heard multiple times is If You Build It, They Will Come. This has launched countless applications/websites/solutions over the past few decades and very few of them actually had people come and use it. But due to confirmational bias people only remember the successes and thus this quote is still used actively in Business schools and by the Startup community. The latest example of this was shared by @nixCraft earlier, where a person spent $300k on an app no one uses.

I’m about to lose my mind and my investor’s money.Developer swears it’s ‘technically perfect’ but I can’t get a single doctor to adopt it. Two years ago we raised a seed round to build a patient management app for primary care doctors. Hired this boutique dev shop, spent 18 months and $300k building what they call a “technically superior solution.” The app works flawlessly. Zero bugs, clean UI, integrates with major EHRs, HIPAA compliant, the whole nine yards. Our developers are genuinely proud of it. But here’s the problem: doctors hate it. We’ve demoed it to 50+ practices. Same feedback every time. “It’s nice but it doesn’t fit our workflow.” “Too many clicks.” “We already have a system that works.” Meanwhile I see these basic-looking apps with terrible UIs getting massive adoption because they solve one specific pain point really well. Starting to think we built the app WE wanted to build instead of what doctors actually needed. Like we got so caught up in making it technically impressive that we forgot to make it useful.

I am awestuck that they managed to spend 300k over 18 months without realizing that no one wanted their solution and then instead of trying to figure out why people don’t want their solution they stuck to their guns and lost even more money.

One of the first things I learnt when I started programming was that your job is to solve problems for the customer, not showcase amazing technology. (If you can do both then that’s awesome). If you look at the quote above, the part in Italics pretty much explains why this app failed. In short the creator was so busy creating a “technically superior solution” that they forgot to create an app that the user actually wanted.

Earlier in my carrier I had the opportunity to work with a NGO that was working with various startups to create technology to help blind people and something they said really stuck with me. He told me that most companies try to create a system that mimic’s how a person would see the world and then translate that into something that a blind person could use and most of these attempts failed miserably because that is not what blind users wanted. They wanted technology that allowed them to interact with the world using their way. We are so used to having the ability to see that we think that if a person can’t see then we need to create something that allows them to see. But that is not what the users are looking for so the tech failed. The one company that had a promising solution spent a good amount of time talking to the prospective users of their technology and then built a solution that addressed specific pain points. Unfortunately, I didn’t stay in touch with the team but I am sure they are doing well because they are solving user problems.

The world’s most awesome and superior technology is of no use if no one actually uses it. We have been trained to think of users as ‘necessary evil’ and their are thousands of jokes around that make fun of users as being somehow clueless and stupid, some oldies call them lusers (a play on the word losers and users). But keep in mind without these users the systems we create are of no use. If you are not solving a business problem (or user pain point) with your solution then you might as well not build it in the first place.

There is one caveat here, you should always find out what problem the user is trying to solve and not just build what the user is asking for without digging into it. A lot of times people will come to you and say that I need XYZ, but when you dig into the problem they are trying to solve you realize that a different solution would be more effective in solving that problem instead.

This is why we need people from the product team to work with the engineering team together to understand what the user wants and how best to deliver that to the user.

Japan opens its first osmotic power plant

Filed under: Emerging Tech,My Thoughts,Science Related — Suramya @ 9:00 PM

As the world is trying to move away from fossil fuels more research is being done on other sources of power generation. Osmotic power generation is one of new latest technologies on the block and Japan has launched its first osmotic power plant, making it the second Osmotic power plant in existence worldwide. This was the first time I heard about Osmotic power so did a bit of research on it as it sounded shady, turns out that it is actually a thing and under experimentation world wide. The Japanese plant is expected to generate about 880,000 kilowatt hours of electricity each year which is the equivalent of powering about 220 Japanese households.

Osmotic energy is a lesser-known form of energy generation that captures the energy generated from the natural salinity gradient between freshwater and saltwater.

This type of energy – also known as “blue energy” – is generated through the natural phenomenon of osmosis. This occurs when water moves from an area of lower solute concentration (freshwater) to an area of higher solute concentration (saltwater) across a semipermeable membrane. When freshwater and seawater meet, a natural gradient in salinity is created, prompting ions to migrate from the saltier side to the less salty side in pursuit of equilibrium. The movement of water and ions generates a pressure differential that can be harnessed to produce electricity. The process resembles a “silent lightning strike” occurring continuously at the confluence of rivers and oceans.

The concept has been around since the early 1970’s but due to the inefficiency of the membranes required, implementation was considered impractical but advances in membrane and pump technology are reducing these problems. That said this technology is still not as scalable as other renewable technologies (as of now) so I doubt that we will start seeing Osmotic power plants being setup all over the place that soon. One option would be to put these plants up near water desalination plants so that the waste water from those plants can be used to generate electricity more efficiently in the Osmotic power plant (With the increased salinity of water used, the plant is more efficient.

It’s nice to read about all these efforts to reduce our dependency of fossil fuels.

Abusing or harassing George R.R. Martin is not going to get his next book published faster

Filed under: Books Related / Reviews,My Thoughts — Suramya @ 9:08 PM

Fans of George R.R Martin have been waiting for the final two books in the ‘A Song of Ice and Fire’ series for over 13 years now and are understandingly eager to have the author finish the books. That being said, just because you are a fan doesn’t give you a right to behave badly with the author. If you search on the web you will see multiple instances of fans cursing out the author or being mean to them just because he hasn’t published the book they are waiting for and that is just not right.

At WorldCon last week another so called fan took this to the next level by literally telling him that:

“Here’s the thing, George, you’re not going to be around for much longer, and this is a tough question I wanted to ask,” the fan began. “This is more directed at Brandon. How would you feel about someone else taking over and finishing the books?”

Who asks something like this to anyone? There are so many other ways they could have asked this question. For example, something Like: “You have been working on this project for a while, when can we expect the next book to be released and do you have a plan in mind for the series if you are unable to finish it for whatever reason?”. This ‘fan’ didn’t expect the backlash from other fans and authors and are now trying to backtrack and justify their behavior but you need to take a hard look at your self if you think that this is acceptable behavior and maybe get some help.

There are so many other authors writing amazing books that I literally don’t have enough time to read all the books that I want to, so maybe try another book while you are waiting for this one to come out. Mercedes Lackey published the last book in the Dragon Prophecy series after almost 9 years (and there are others that were published after decades) and guess what, the world didn’t end because she took longer to publish the book. Personally I would rather wait a bit longer for a book to be published so that the author can polish it and ensure it is good than read a half baked book that was pushed out on because of time constraints.

Check out the comments to the story at collider.com and there are idiots who are trying to justify this behavior. One example comment: “*I love George’s work, but come on, “Stan” has a valid point. George needs a little fire put under his butt to finish both books. For those who do not know, Winds of Winter has taken 14 years so far, and he claims that it’s only 75% finished. UGH…..”

Authors are not robots that are there to serve you and produce entertainment for you, they are human beings with human feelings and emotions. You really think George Martin is going to feel like writing immediately after dealing with this nonsense? Of course not. But for these so called fans emotions other than anger are for the weak, all they know is that their desires should get fulfilled immediately no matter how the other person feels as evidenced by the comment: “Ah, did poor widdle Georgie get his feeling hurt by da big bad fan?”

Stop trying to gatekeep Women and ‘others’ in Tech

Filed under: My Thoughts,Tech Related — Suramya @ 9:47 AM

Lesley made this ‘simple’ request on Mastadon “Guys,Please. Be better than the commenters.” while linking to the screenshot below. It is really sad that it’s 2025 and we still have idiots try to gatekeep people out of ‘their’ playhouse.

Full text below the screenshot
Idiot:Fucking tourists.
Jessica Weiland: Ah so you are a kind one. Thank you for the positive feedback and the willingness to make security accessible and easy to understand for all.
Idiot:Jessica Weiland this is our world. You had yours. You ruined it. Now
Jessica Weiland: What is your world, please do tell.
Idiot: the world of the electron and the switch, the beauty of the baud. We fled here when women like you laughed at us when we were 13. Now you’re here too. Fuck off.

What a sad life they must have to be so threatened by everyone and everything. The irony is that the quote he makes “the world of the electron and the switch, the beauty of the baud.” is from the Hacker’s Manifesto aka The Conscience of a Hacker and was famously quoted in the movie Hackers and is considered a cornerstone of hacker culture (the original meaning not the folks breaking into systems). He just doesn’t quote the full text because it contradicts the nonsense he is sprouting. Below is the relevant section, and I have bolded the important part that he is ignoring:

This is our world now… the world of the electron and the switch, the
beauty of the baud.
We make use of a service already existing without paying
for what could be dirt-cheap if it wasn’t run by profiteering gluttons, and
you call us criminals. We explore… and you call us criminals. We seek
after knowledge… and you call us criminals. We exist without skin color,
without nationality, without religious bias… and you call us criminals.
You build atomic bombs, you wage wars, you murder, cheat, and lie to us
and try to make us believe it’s for our own good, yet we’re the criminals.

Yes, I am a criminal. My crime is that of curiosity. My crime is
that of judging people by what they say and think, not what they look like.

My crime is that of outsmarting you, something that you will never forgive me

What is really relevant is the last line which is what this guy is most upset about. In his mind You can only be the best if you keep the riff-raff (meaning anyone not like them) out.

This is where we all come in, We all need to stand up to this nonsense and call it out when and where we see it. It’s not just a joke, it is extremely demoralizing for someone to be told that they don’t belong and are not good enough to be in Tech. It seems funny to us because we are not the butt of the joke, put the shoe on the other foot and you will realize how unfunny it is. If you are threatened by the girl (or anyone else) in the team because they are better then use that excuse to work towards improving your skill, learn from them. Remember it is not a zero sum game and a rising tide lifts all boats so if your team is strong it will help you as well.

The women in tech have been systematically whitewashed out of our history. For example did you know that a woman (Hedy Lamarr) pioneered the wireless & frequency hopping technology that would one day form the basis for today’s WiFi, GPS, and Bluetooth communication systems? There are a million such examples and then there are the unknown geniuses whose husbands/bosses/coworkers take credit for their work leaving them in the dark while profiting from the work they did.

Remember it is not their world. It’s ours. The world of the electron and the switch, the beauty of the baud where we exist without skin color,without nationality, without religious bias… Yes, I am a criminal. My crime is that of curiosity.

Lessons learnt from AWS deleting a 10-year account and all that data without warning

Filed under: My Thoughts,Tech Related — Suramya @ 11:31 PM

The Tech industry has successfully convinced almost everyone that moving to the Cloud is the best option for them and in a lot of cases it is true. If you are a startup or trying out new idea’s or a small shot that doesn’t have a full time IT staff then it is more cost efficient and quicker to run everything on the cloud so that you don’t have to worry about it. However, remember what they say:

There is no cloud, it's just someone else's computer
There is no cloud, it’s just someone else’s computer

Once your data is on their computer you don’t really have full control of it anymore. If it is unencrypted then they can access it and depending on their terms of service use it for various purposes like training their AI models etc. If asked they can share your data with US law enforcement or others even if the server is physically not in the US. (Microsoft admitted under oath that it ‘cannot guarantee’ data sovereignty)

Another major risk is that if your account gets deleted or frozen for whatever reason then you loose all the data stored there with almost no recourse in most cases. Hacker News and Reddit are filled with threads where people have suddenly been locked out of their accounts and are desperate to get through to someone that can restore access. The latest instance of this is where Seuros who is a very prominent Open Source developer had their 10 year old account on AWS deleted without warning with no possibility of recovering the data. Then AWS tried to cover up their mistake and refused to give clear answers on the status of the data for over 20 days.

Seuros did almost everything correctly, they had a comprehensive backup strategy that:

  • Multi-region replication across AWS Europe (completely separate from US infrastructure)
  • Dead man’s switch implemented for disaster recovery
  • Proper backup architecture following AWS’s own best practices
  • Segregated encryption keys stored separately from data

But the only thing that they didn’t account for was the possibility that AWS itself would be the cause of the data loss across all the backups and redundancies. If you have data that you want to preserve you should ensure that you have a local copy of all the data no matter what service guaranty your cloud providers are giving. Nothing in the world is 100% secure/safe so if you don’t have a local copy then there is a possibility that you can loose the data permanently.

Some people will suggest instead of a local copy you can have copies on multiple cloud servers but that has a recurring cost implication to it. I would rather buy an external drive for a few hundred dollars and then periodically sync your data to it. This ensures that you have a copy of the data in your control no matter what happens to it on the server side.

If your cloud provider (Google Photos or Drive/AWS/Azure/Dropbox etc etc) is the only place you have copies of important data then you are risking complete loss of the data for something that isn’t in your control. Think about it before you put all your eggs in one basket.

BSNL offers 4G internet with 2GB per day for 1 Rs only.

Filed under: My Thoughts,Tech Related — Suramya @ 7:34 PM

Internet has become a necessity in the modern world and with so many of the services and functionality moving online it is more and more important that folks are able to connect to the internet cheaply. In 2020 (The last time I had looked at this), India had the cheapest mobile data in the world with the average cost of 1GB of mobile data are India ($0.09), Israel ($0.11), Kyrgyzstan ($0.21), Italy ($0.43), and Ukraine ($0.46).

Bharat Sanchar Nigam Limited (BSNL) which is a government-owned telecom network has launched a new offer that beats the 2020 costs hands down. They have launched a mobile data plan for new customers that offers unlimited voice calls and 4G data (2GB per day) at just Re 1(0.011 USD) per month.

This is an awesome offer and would be a tough competitor for the other mobile data providers. I expect other providers to start offering significant discounts in the near future as well just as they did when Jio launched their solution.

Watched Superman & Fantastic 4 and they both are awesome

Filed under: My Thoughts — Suramya @ 3:15 PM

Watched the new Fantastic 4 movie over the weekend and had watched Superman last week. I loved both the movies and am super happy that we have finally moved away from making everything dark & gritty. A lot of movies were made/rebooted into these dark/gritty reboots and while some of them were good movies I prefer watching the more light hearted versions. For example, the Teenage Mutant Ninja Turtles I loved most was the 80’s cartoon version and the 90’s movies where they are goofing off and still fighting crime. The reboots (both the cartoons and the movies) were recast to a darker version taking the fun out of it.

Some movies or characters can survive being recast as dark such as Batman which always has a darker tone (except for the 60s’ TV show but others don’t work that well. Superman is one such character, he is supposed to embody hope and optimism but the last few movies had a darker tone and were definitely not hopeful. So it was good to watch a lighthearted and hopeful movie instead of the now standard brooding hero. A bunch of whiners (the usual suspects) are upset that Superman is hopeful and a story that says basic human kindness is a value. So they are calling the movie ‘woke’ and calling for a boycott.

Superman is in its third weekend in theaters and currently the highest-grossing superhero film of 2025 with a box-office earnings of $472.4 million globally as of now. So the whiners are falling over backwards to call the movie a flop but the numbers and the ratings just don’t support them at all.

Rex Huppke wrote a fantastic article about the movie that goes into more details on why some folks hate the movie because the character is the champion of the oppressed and also known as the world biggest boyscout.

I loved the portrayal of Lex Luthor in the movie and feel that this is the best iteration of the character followed by the one in smallvile and then Lex from the ‘Superman & Lois’ series. The absolute pettiness of his jealousy comes through fantastically on screen and you can see how Lex just doesn’t care about anything other than taking Superman out even if it means destroying the world. The rest of the support cast was quite good as well and acted brilliantly. The story was a bit light on substance but the acting and I guess you can call it the heart of the story compensated for it quite well.

Coming to the The Fantastic 4 movie, it was a fun watch as well. Thankfully it wasn’t yet another origin story though they did cover their origins in the first few mins of the movie and then got to the more interesting part of the show. Galactus was imposing and scary in the movie. Johnny storm kept true to the character and goofed around as always but had hidden depths and strength which made an interesting contrast. I loved the fact that Sue storm was portrayed so well and actually shown to be powerful in her own right instead of being there just for eye candy with limited action while the other 3 did most of the work to address the threats they are facing.

Can’t give more details without spoilers so I will just say this: go watch the movie. It is a fun romp and do stay for the post credits scene as it is awesome.

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