Transparent Solar Panels hit Record 8.1% Efficiency

Filed under: Emerging Tech,My Thoughts,Tech Related — Suramya @ 5:24 PM

Solar panels for electricity are awesome, however the major issue with deploying solar panels is that you need a lot of space for them. Although the efficiency of the panels has been going up reducing the space requirements but its still a non-trivial amount of space to generate enough power to be useful to power a house, Portable solar panels are well and good but they are slow and expensive. I tried to figure out a way to power my apartment via solar power but it wasn’t possible without having panels setup on the apartment roof.

Which is where the Transparent Solar panels come into play as they allow you to replace your existing windows for solar panel which would make them ideal for Apartments & office buildings. Because you don’t need extra space for the panels and just need to replace the windows. The transparent solar panels were created in 2014 by researchers at Michigan State University (MSU) however the efficiency of the panels was quite low compared to the traditional panels making it less productive and more expensive than the traditional panels so since then the race has been on to make the panels more efficient.

The researches from University of Michigan have made a significant break through in the manufacturing of color-neutral, transparent solar cells achieving 8.1% efficiency by using a carbon-based design rather than conventional silicon. The created cells do have a slight greenish tinge like sunglasses but for the most part appear to be usable as a window pane. More details are available in their release here.

The new material is a combination of organic molecules engineered to be transparent in the visible and absorbing in the near infrared, an invisible part of the spectrum that accounts for much of the energy in sunlight. In addition, the researchers developed optical coatings to boost both power generated from infrared light and transparency in the visible range—two qualities that are usually in competition with one another.

The color-neutral version of the device was made with an indium tin oxide electrode. A silver electrode improved the efficiency to 10.8%, with 45.8% transparency. However, that version’s slightly greenish tint may not be acceptable in some window applications.

Transparent solar cells are measured by their light utilization efficiency, which describes how much energy from the light hitting the window is available either as electricity or as transmitted light on the interior side. Previous transparent solar cells have light utilization efficiencies of roughly 2-3%, but the indium tin oxide cell is rated at 3.5% and the silver version has a light utilization efficiency of 5%.

The researchers are still working on improving the efficiency further and I am looking forward to the new breakthroughs in the field. Hopefully soon we will have panels efficient enough that I will be able to replace my apartment’s windows with Solar panel and break even in a reasonable amount of time. 🙂

Convert typed text to realistic handwriting

Filed under: Computer Related,Computer Software,Tech Related — Suramya @ 6:45 PM

There are some tools or projects that really don’t make any practical sense but are a lot of fun to use or just impressive in how they implement technology. The Handwritten.js project by ‘alias-rahil’ is one such project. Basically what it does is take any Plain Text document and convert it into a realistic looking handwritten page. I tried it out on a few sample documents (logs) and it worked great. The programs does coredump if you try converting a 5MB file, but other than that it worked as expected.

Below is a sample file with some quotes that I converted as a test :

* Mountain Dew and doughnuts… because breakfast is the most important meal of the day

* Some days you’re the dog; some days you’re the hydrant.

* He who smiles in a crisis has found someone to blame.

* Marriage is one of the chief causes of divorce

* Earth is 98% full…please delete anyone you can.

* I came, I saw, I decided to order take out.

* F U CN RD THS U CNT SPL WRTH A DM!

* Work hard for eight hours a day, and eventually you may become a
boss and be able to work twelve.

* Quitters never win, and winners never quit, but those who never quit AND never win are idiots.

* What’s the difference between a bad golfer and a bad skydiver?

A bad golfer goes, WHACK! “Damn.”
A bad skydiver goes, “Damn.” WHACK!

* Beware of the light at the end of the tunnel. It could be an oncoming train.

* A girl is like a road. The more curves she has the more dangerous she is!

* A woman who dresses to kill probably cooks the same.

The script is fast and didn’t take more than a few seconds to process the file and create a PDF file with the output. The output for my test run is as below:


Output generated by Handwritten.js

I did also try converting a word file with the software but it didn’t take the content of the file for the conversion, instead it converted the XML & Code from the file. One suggestion for improvement I have is to enhance the script to support word files. It would be awesome if it could also convert any of the diagrams, tables etc to look like they were drawn by hand.

Maybe if I have some time I will look into this and see how easy it is to enhance the script. But no promises as I have a ton of other things I need to take complete first. 🙂

Finally moved the Website & Blog to https

Filed under: Computer Tips,Tech Related,Website Updates — Suramya @ 12:02 PM

After spending way too much time avoiding the work due I finally configured both suramya.com & the Blog to be https by default. The setup was fairly simple, I added the certificate on the 1and1.com portal, then after a few mins I was able to access the site over https. In order to redirect http to https automatically I followed the following steps:

Auto Redirect to https in Apache

Configure .htaccess to force a redirect, you can also configure it in the Apache main configuration (under the virtualhosts directive) but since I don’t have root access and can’t modify it I updated the .htaccess config to do the same thing. Basically you need to add the following lines to .htaccess :

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.suramya.com/$1 [R,L]

Change www.suramya.com to your domain, else every visitor to your site will be sent to my site. Not that I will mind that, but you might. 🙂

Then I did the same thing for the blog with a small change, The .htaccess for the blog reads as the following:


RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.suramya.com/blog/$1 [R,L]

When updating the file, you need to ensure you put the changes outside the # BEGIN WordPress & # END WordPress as the content is dynamically generated and would be overwritten.

Updating all the urls in WordPress

After I made the changes above, I found that the site was being redirected to https but I was getting errors about mixed content on the page because all the URL’s/Images that I had uploaded to WP till now were saved as http and not https. So I had to change every URL in the blog from http to https and to be honest I wasn’t looking forward to doing this manually. I searched the web and found this site that had instructions on how to update the url’s using the WordPress commandline interface. From the blog directory you need to issue the following command:

wp search-replace http://www.suramya.com/blog/ https://www.suramya.com/blog/ --dry-run

This command does a dry run and tells you what all changes will be made and if everything looks ok, then you can run the above command again without the ‘dry-run’ call.

wp search-replace http://www.suramya.com/blog/ https://www.suramya.com/blog/

If all goes well you will get an output similar to the following:

Success: Made 3992 replacements.

That’s it. After running the command, the blog is completely on https and the security gods are happy :). Now I need to update all the URL’s on the main site to reference https instead of http and that is going to be painful. It will require a whole lot of script-fu to do it automatically as it will have to be a regex/awk or something similar. Maybe someone already did the work and posted the solution online. Alas that was not the case. I ended up manually updating the files since there were only about 20-25 of them. Opened all of them in the editor one-shot and then did a search & replace. Now both sites are coming up properly in https.

Issue with Site Posts

Filed under: Website Updates — Suramya @ 2:50 PM

Update 8/17/2020: Issue resolved. The problem was caused because I had a missing single quote in the previous post. Once I added the quote to the post things went back to normal.

There seems to be an issue with WordPress where some of my posts have gone MIA on the main page even though the direct links work. Also some of the posts are being merged together for some reason.
I am looking into it, so please be patient.

Parents freaking out about their kid being fed Indian food and my thoughts on it

Filed under: My Thoughts — Suramya @ 2:31 PM

A few days ago a post popped up in my twitter feed where this person was complaining about how they had sent their kid (‘Chris’) to a friends place (‘Neil’) and Neil’s parents fed Chris Indian food without asking for permission from the parents. Neil’s parents are both Doctors of Indian origin and settled in the US. This guy was complaining about how they should have asked him for permission because kids tummies are sensitive etc etc and wanted to know if it was ok to tell Neil’s parents that they would only allow Chris and Neil to play at their house going forward. This was sent to a online help personality “Dear Prudence” and they posted it online. When I first saw the headline (“Help! I can’t believe my Son’s friend fed him Indian food without calling me first”) I thought it was a joke so I clicked to get more details which are in the screenshot below:

This is incredibly controlling behavior from Chris’s parents and I think there is a race aspect to the whole thing as well which is evident from the comment near the end about how further conversations on the topic would be racial in nature. There is no mention anywhere about any Allergies or diet restrictions that Chris might have, and if that was the case I understand the parents panicking when the kid is fed something that could be actively dangerous to them or if they were vegetarians and the kid was fed meat. But panicking just because they were fed spicy food is a bit too much.

As a kid I couldn’t handle any Spices and my food was made with minimal levels of spice, then I was visiting relatives who fed me Radish with salt, lemon & chilly powder and I loved it. I felt that my tongue was about to fall off but I loved it and slowly started increasing my spice tolerance. As a kid and even now I eat at my friends place all the time. Some of the food are things that I had never eaten before and it was an experience trying out new cuisines and food. We had a south-Indian family living next to us when Dad was posted in Delhi and we (me & Surabhi) were at their house every other day eating whatever they had cooked, which was my first experience of South Indian food that I remember. Surabhi fell in love with the Dosa’s & Idli’s etc at the time and till date its her favorite food. When they would come to our place we fed them classic north Indian dishes and they loved it as well…

Variety is the spice of life and food from other parts of the world is amazing. Chris’s parents should be happy that he is getting to experience other cultures and traditions at such a young age. When we travel we always explore the local food and try to each as much of it as possible. Which is why as times I do feel sad that I am a vegetarian because of which I can’t try the authentic local cuisine at a lot of places but I still make the effort to try the veg options. When I was in the US we had a whole semester where we went out every weekend to try a new cuisine and it was awesome. There were times that I hated the dish I ordered but that’s still part and parcel of exploring. I fell in love with Mexican food because I ate it in the US, if I had stuck to Indian food as a few of my friends did then I wouldn’t have found out about this amazing cuisine.

In my opinion there is no food that is inappropriate, there could be food that you can’t eat due to restrictions, medical issues or whatever but that’s it. In this case Chris’s parents are teaching their kid that ‘foreign’ food is something bad/dangerous and needs to be avoided. We are in a global world now, I can guarantee that Chris will end up with Indian friends/co-workers (or folks from other nationalities) down the line and have to eat the food. Its better that he tries the food now and gets used to it than have issues later in life.

What do you think?

Updating the BIOS to address a AMD Ryzen bug

Filed under: Computer Related,Computer Software,Tech Related — Suramya @ 5:13 PM

Over the past few months I have been infrequently seeing the following warning message in the Terminal and had been ignoring it because apparently the fix was to update the BIOS and I didn’t have the patience/time to do the upgrade at that point in time:

WARNING: CPU random generator seem to be failing, disable hardware random number generation
WARNING: RDRND generated: 0xffffffff 0xffffffff 0xffffffff 0xffffffff
WARNING: CPU random generator seem to be failing, disable hardware random number generation
WARNING: RDRND generated: 0xffffffff 0xffffffff 0xffffffff 0xffffffff

Today I thought that I should fix the error, a bit of Google searching confirmed that I needed to update the BIOS because apparently there was a bug in the AMD Ryzen 3000 series processor that causes the onboard random number generator to always return 0xffffffff when asked to generate a Random number. Obviously getting the same number every time is not optimal even though Dilbert feels otherwise.


Random Number Generator in Accounting

AMD was notified about it last year and they released a BIOS update to fix the issue, however each Motherboard company had to validate and release the new BIOS which took time. The fix was to upgrade the BIOS and I really wasn’t looking forward to it as the last time I upgraded the BIOS it was a painful exercise involving floppy disks and cursing etc.

I looked up my BIOS version using the dmidecode command but that didn’t give me enough information to find the new BIOS version for my motherboard (‘ROG STRIX X570-E GAMING’). So I rebooted the computer and found the built in BIOS upgrade section under Tools. I decided to give it a try and see what options are available so I clicked on the Upgrade option and it gave me the option of connecting to the Internet and automatically downloading the latest version of the BIOS or installing it from a USB/Disk Drive. I selected the Network Install option and the system happily downloaded the latest version of the BIOS from the Internet and then gave me the option to Install the new version. I selected ‘Yes’ and the BIOS was upgraded.

The system had to reboot a few times for the upgrade to complete and there was a boot where the system played a bunch of beeps without anything coming up on the display which scared the life out of me but then it immediately rebooted and the display came back. After the upgrade completed I got a screen with a bunch of messages about BIOS settings needing to be reinitialized but when I went into the BIOS the settings were all there. So I rebooted and now all looks good and I don’t see any more weird error messages in the Console or the logs.

I am happy to see that the process to upgrade the BIOS is now so simple and I will be upgrading the BIOS more frequently going forward.

Penguin Poop Seen From Space Leads To Discovery of New Colonies

Filed under: My Thoughts — Suramya @ 4:16 PM

If we go back in time to 1957 and tell people that in future Satellites are going to be powerful enough to detect Penguin Poop from space they would look at you as if you were insane. However now due to improvements in the Satellite-mapping technology we now have the capacity to detect & identify Penguin poop from space. At first this might sound ridiculous and you might be asking why would we spend the time and effort to be able to identify poop from space. Basically the problem we are trying to solve is to locate penguin nesting sites to get an idea of how many penguins are there in the wild and how endangered they are currently.

Traditional methods involve going across Antarctica and other places where they nest to find their nesting places. This is very time consuming, expensive and at times dangerous. The first survey folks used sledges etc to travel across, then we moved on to using planes to view the area from the air now we can do it remotely without leaving the comfort of our homes thanks to the advances in technologies. The scientists used images from Europe’s Copernicus Sentinel-2 mission and were able to identify Eleven new Colonies of the Emperor penguin.

Satellite-mapping technology that detects stains on the ice from penguin droppings has revealed there are nearly 20% more Emperor colonies than previously identified in fast-warming Antarctica.

“This is an exciting discovery,” said lead author and geographer Peter Fretwell in a statement. “Whilst this is good news, the colonies are small and so only take the overall population count up by 5-10%, to just over half a million penguins.””

The discovery will be used by scientists who are monitoring the birds and raising concerns because they’re particularly vulnerable to sea ice melting from climate change… Scientists warned that most of the newly found colonies are in locations likely to be lost as the climate warms and large sections of seasonal ice — where penguins mate — risk disappearing. “Birds in these sites are therefore probably the ‘canaries in the coal mine’,” said Phil Trathan, head of conservation biology at BAS.

While its great that there are more Emperor Penguins than we thought they are still at risk of extinction due to Global Warming/Climate Change. We need to seriously spend more effort to combat Climate change and the time to make the changes is running out faster than we thought.

Thoughts on Cybercrime in the Covid world

Filed under: Computer Security,My Thoughts,Tech Related — Suramya @ 1:07 PM

The Cyber Security industry has seen a massive boost during the current pandemic, with users working remotely for the first time and permissions granted on the fly the Security teams in the enterprise have been working round the clock to ensure critical data and systems are secure. But due to the general chaos of Covid combined with the need to keep businesses running there are systems that have been less than optimally configured.

All this gives us the impression that the Cybercrime world must be thriving in the current environment. But apparently that is not always the case, the Cambridge Cybercrime Centre has released a series of reports on how the Pandemic has impacted cybercrime. The reports are a fascinating read as they show how even the criminals are facing hardships due to the pandemic. For example, below is an extract from the report on the impact on International drug trade due to the shipping disruptions caused by lockdowns.

“The initial wave of COVID lockdowns in China caused substantial disruption to international shipping,compounded by the subsequent lockdowns in the rest of the world. Despite their ‘online’ character, drugscryptomarkets (online markets for legal and illegal drugs which are accessed securely through anonymitynetworks such as Tor) are reliant on the postal and shipping services for the delivery of drugs and precursorsto suppliers and end users. We have observed, in our scraped datasets of illicit online forums and discussionboards, evidence of significant disruption of these pathways, and a range of effects on these illicit markets.At the initial peak of lockdown measures, shipping times (especially in international routes which passedthrough China) were being routinely delayed by up to three months (as reported in cryptomarket discussions).This caused significant friction to international orders for postal drug delivery, with many dealers reportingthat they were switching to orders within the same nation only, and others struggling to source supply.”

Brian Kerbs from Kerbs on Security wrote a comprehensive article on How Cybercriminals are Weathering COVID-19 and its worth a read as well.

But apparently a number of criminal reshipping services are reporting difficulties due to the increased wait time when calling FedEx or UPS (to divert carded goods that merchants end up shipping to the cardholder’s address instead of to the mule’s). In response, these operations are raising their prices and warning of longer shipping times, which in turn could hamper the activities of other actors who depend on those services.

That’s according to Intel 471, a cyber intelligence company that closely monitors hundreds of online crime forums. In a report published today, the company said since late March 2020 it has observed several crooks complaining about COVID-19 interfering with the daily activities of their various money mules (people hired to help launder the proceeds of cybercrime).

The same is happening for real world crime also, Jani was telling me about this article on Goa where the local drug dealers are out of job because no tourists are visiting so they all are now selling fish to survive.

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

Interested in Coding using emoji’s? Check out emojicode

Filed under: Computer Software,My Thoughts,Tech Related — Suramya @ 12:12 PM

I am not the most fervent fan of emojis in the world and for the most part I have gone through the last 20+ years with about 3-4 emojis that I use on a regular basis. But I know people who communicate wholly using them and while I am ok with folks using them in personal communications I dislike them immensely in professional communications (except for the occasional smiley face). However not everyone agrees with me and there have been books published in the past using just Emoji’s and now there is a programming language that is written entirely in emoji.

Emojicode, which first appeared as a Github project back in 2016 has been around for a while now and has a fairly strong following in the tech world. I realize that I sound like one of the old men screaming ‘Get off my lawn’ but I really don’t understand why anyone would want to code in a language that uses emoji’s to define text as a serious programming language. As a joke it would be fun to learn but I can’t really imagine coming in to work one day and writing code using Emojocode for a work project.

Here’s an example of the “Hello World” program written using Emojicode.


Hello World using Emojicode

If you want to learn coding in Emojicode, you can check out their impressive documentation or do a Code Academy course on the language. Emojicode is open-source, so you can also contribute to the development via their GitHub repository.

Yes, learning new programming languages is cool, but I don’t think I will be spending the effort to learn Emojicode anytime in the near future.

Scientists claim to be able to detect depression in written text using Machine learning

Filed under: Computer Software,My Thoughts,Tech Related — Suramya @ 12:26 PM

Depression is brutal, it can range from feelings of sadness, loss, or anger that interfere with a person’s everyday activities to suicidal tendencies. In the past few months there have been multiple cases of famous people committing suicide because they were depressed and unable to cope with the feelings of isolation and stress brought about by the current pandemic. Unfortunately depression is not an easy thing to diagnose and there isn’t a single test to diagnose it. Doctors can diagnose it based on your symptoms and a psychological evaluation which in most cases includes questions about your:

  • moods
  • appetite
  • sleep pattern
  • activity level
  • thoughts etc

But all of this requires a person to be open about their thoughts and that can be difficult at times due to the stigma associated with mental health issues. In all of the cases I was referring to earlier the common theme from the friends & acquaintances have been about how they wish they had known that xyz was depressed and if they had then maybe they could have helped.

The problem is that people don’t always come out and say that they are depressed and sometime the signals are very faint. So its very interesting to see the various efforts that are underway to identify these symptoms earlier and get the people the help they need faster so that they don’t have to face it alone. As part of this effort scientists at Canada’s University of Alberta have created a machine learning model that uses linguistic clues to indicate signs of depression in text communications like twitter messages and have published a paper on it (Augmenting Semantic Representation of Depressive Language: From Forums to Microblogs) in the ‘European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Database’.

We discuss and analyze the process of creating word embedding feature representations specifically designed for a learning task when annotated data is scarce, like depressive language detection from Tweets. We start from rich word embedding pre-trained from a general dataset, then enhance it with embedding learned from a domain specific but relatively much smaller dataset. Our strengthened representation portrays better the domain of depression we are interested in as it combines the semantics learned from the specific domain and word coverage from the general language. We present a comparative analyses of our word embedding representations with a simple bag-of-words model, a well known sentiment lexicon, a psycholinguistic lexicon, and a general pre-trained word embedding, based on their efficacy in accurately identifying depressive Tweets. We show that our representations achieve a significantly better F1 score than the others when applied to a high quality dataset.

This is not the first study on the topic and it won’t be the last. The paper is fairly technical and from what I can understand they can identify potential signs of depression based on words used and phrasing. But am not sure how they are taking into account sarcasm and contextual clues. For example without the appropriate context things being said can be taken in many different ways and identifying the correct emotion behind the words can be tricky. When we interact in person or over phone things like body language or verbal cues give us additional context about how a person is feeling, unfortunately that is not the case with text and there is a huge potential for things to be taken out of context or in the wrong way. Another issue is how to differentiate between feelings of sadness and depression as the symptoms might be very similar.

We need human interactions, connections etc to address this issue and not another technology claiming to be a silver bullet as not everything can be solved by AI/ML and the low accuracy level on such solutions can only cause trouble down the line. Imagine such a system being implemented at workplaces, during interviews or on dating sites. If a system flagged you as a depressive then it could cost you your job, or your relationship.

What do you think?
