Using LLM’s to change writing style to hide author?

Filed under: Artificial Intelligence,My Thoughts,Tech Related — Suramya @ 12:17 PM

It is fairly well known that folks can identify a writer based on their writing style. In fact there is a whole field of work called Stylometry that analyses writings to try to attribute authorship of documents/writings. This is used in when new text/writings are found that are not attributed to any person or when agencies receive letters or there are articles posted on extremist sites.

In 1964, Frederick Mosteller and David Wallace published a three-year study of the distribution of common words in the Federalist Papers and showed that the writing style of Alexander Hamilton and James Madison differed in subtle ways. The researchers analyzed some disputed papers that both writers claimed to have written and based on their analysis of the respective writing styles of both authors were able to identify that the papers were likely to have come from Madison’s pen. Since then the technique has only improved, with AI and Machine learning algorithms coming into play researchers are able to identify the writing style from a post quickly and mostly accurately. Keep in mind that this is still more of an art than a science. However, it works well enough that people were able to identify the author of a book: “The Cuckoo’s Calling, by Robert Galbraith” as none other than JK Rowling.

Now, as we all know “With every action there is an equal and opposite reaction” and there has been a lot of work put into what is called Adversarial stylometry. Which is the practice of consciously changing the writing style when writing so remove the identifying characteristics that can be used to figure out who wrote the text. Historically, this was achieved by paraphrasing the text and by having another person edit & modify the content.

With the recent advances in LLM especially systems like ChatGPT it might be possible to use them to whitewash the text and remove enough identifying marks that the text becomes relatively more anonymous. I tried it out with the previous paragraph as the input and got the following as the result:

As commonly understood, the principle of “For every action, there is an opposing reaction” holds true. Considerable effort has been dedicated to a field known as Adversarial Stylometry. This involves intentionally altering one’s writing style to eliminate distinctive traits that could be employed to determine the authorship of a text. In the past, this was accomplished by rephrasing the content and enlisting the assistance of a third party to revise and adjust the material.

As you can see the output is significantly different in both words, tone and phrasing that it would it hard to attribute correctly. Do it a few times in a loop and after ensuring the original meaning is not lost you can use it and be relatively sure that it will be difficult to identify the author of the text.

Obviously, if LLM’s are going to be used to obfuscate text then other LLM’s will be created that try to de-obfuscate the text and the systems will keep getting more and more smarter.

ISRO Aditya mission to the Sun is scheduled to Launch this Friday

Filed under: Astronomy / Space,My Thoughts — Suramya @ 12:39 AM

After successfully landing Chandrayaan-3 on the Moon, ISRO is not resting on its laurels. Their next mission (Aditya L1) is on schedule to launch on 1st Sept 2023 and this will be the first space based Indian mission to study the Sun. The craft, named after the Hindi word for the sun, will be launched from the spaceport in Sriharikota using India’s heavy-duty launch vehicle, the PSLV, which will travel about 1.5 million km (932,000 miles). The craft will be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which gives it the advantage of continuously viewing the Sun without any eclipses or blockages. So far only 3 other countries/entities have successfully launched Solar probes: NASA (US), DFVLR (Germany), ESA (European Union). ISRO will be the 4th to do so.

Citizens are invited to witness the launch from the Launch View Gallery at Sriharikota by registering at their website. This is an awesome improvement in the process to visit the launch site. A few years ago when Surabhi and Vinit wanted to take the kids to watch the launch, they ended up having to reach out to an ISRO scientist and use a personal connection to get access. Now we can do it via a website. The advantage is that this is building up the hype for ISRO and getting more people interested in space.

The Science Objectives of the mission are as follows:

  • Study of Solar upper atmospheric (chromosphere and corona) dynamics.
  • Study of chromospheric and coronal heating, physics of the partially ionized plasma, initiation of the coronal mass ejections, and flares
  • Observe the in-situ particle and plasma environment providing data for the study of particle dynamics from the Sun.
  • Physics of solar corona and its heating mechanism.
  • Diagnostics of the coronal and coronal loops plasma: Temperature, velocity and density.
  • Development, dynamics and origin of CMEs.
  • Identify the sequence of processes that occur at multiple layers (chromosphere, base and extended corona) which eventually leads to solar eruptive events.
  • Magnetic field topology and magnetic field measurements in the solar corona .
  • Drivers for space weather (origin, composition and dynamics of solar wind .

Full details of the mission are available at the ISRO: ADITYA-L1 Website. Will write more after the launch.

Excel holding up the Global Financial System, now with Python support

Filed under: Computer Security,Computer Software,My Thoughts,Tech Related — Suramya @ 1:12 PM

It is both impressive and scary how much of the world’s financial systems is being run using Microsoft Excel. Folks have created formulars/macros/scripts/functions etc in Excel that allows them to generate data that is used to take major financial decisions with real world impact.

In one of my previous companies we actually had a full discussion on how to get an inventory of all the Excel code in use at the company and how to archive it so that we have backups and version control on them. Unfortunately, I left before much headway was made but I did learn enough about excel use to scare me. (Especially since I am not the biggest fan of Microsoft software 😉 )

Now you might ask why so many people are using excel when there are better tools available in the market and these companies have inhouse teams to create custom software for the analyst and I asked the exact same questions when I started. I think it is probably because the tool makes it easy for folks to come up with formulas and scripts that get their work done instead of having to wait for an external team to make the changes etc that they need.

Now, a few days ago Microsoft made a surprise announcement that going forward they are going to support running Python inside an Excel file. Yikes!! In order to use this functionality you will need to be part of the Microsoft 365 Insider program and then you can type Python code directly into cells using the new =PY() function, which then gets executed in the cloud. From what I have read, this will be enabled by default and needs to be disabled via a registry key.

Since its inception, Microsoft Excel has changed how people organize, analyze, and visualize their data, providing a basis for decision-making for the millions of people who use it each day. Today we’re announcing a significant evolution in the analytical capabilities available within Excel by releasing a Public Preview of Python in Excel. Python in Excel makes it possible to natively combine Python and Excel analytics within the same workbook – with no setup required. With Python in Excel, you can type Python directly into a cell, the Python calculations run in the Microsoft Cloud, and your results are returned to the worksheet, including plots and visualizations.

We already have issues with Excel Macros being used as vectors for malware & viruses, this just opens a whole new front in that war. Now, admins will have to worry about attackers using Python in Excel to infiltrate the organization or to send data outside the org. I can see how it is useful for people working with datasets and MS is adding this functionality to keep up with other tools such as Tableau etc which are more powerful but still I feel that this is a bad move.

Another problem that folks are going to face is that now your Excel sheets have Python programs inside them, how are we supposed to version the code, how is code review done? Basically this code should be going through the standard SDLC (Software Development Life Cycle) process but wouldn’t. We also need to ensure that all changes are reviewed and monitored to protect against insider attacks but the way the system is setup this is going to be extremely difficult (We have already seen that with Macros and Formulas etc).

Lets see how folks address this risk profile.

ISRO’s Chandrayaan-3 Successfully lands on the Moon!!!

Filed under: Astronomy / Space — Suramya @ 6:33 PM

We did it!!!! India made it all the way to the moon on its home grown Spacecraft and successfully achieved a soft landing on the Moon! This is a proud day for India and Indian’s world wide. We achieved something that only a few other countries have achieved so far and now India’s ambition to put up our own orbital station doesn’t seem that far fetched anymore…

The Indian Space Research Organisation’s (ISRO’s) Chandrayaan-3, which takes its name from the Sanskrit word for “mooncraft”, took off onboard a Launch Vehicle Mark-III rocket from the southern state of Andhra Pradesh on 14 July and has spent six weeks covering about 380,000 kilometres en route to the moon. It was a remarkably smooth landing process to the point that it wasn’t immediately apparent that it had touched down…

The news conference is ongoing: ISRO Live Telecast

Will post a more detailed post with my thoughts later on but for now: We are on the MOON!!!

Jai Hind!

Getting my Pocket C.H.I.P. to finally work

Filed under: Knowledgebase,Linux/Unix Related,My Thoughts,Tech Related — Suramya @ 11:59 PM

Way back in 2016, I backed the Pocket C.H.I.P on Kickstarter opting to get 2 CHIP’s and one PocketChip. The C.H.I.P (or CHIP) was a single single-board computer costing $9 launched by Next Thing Co. It used open-source hardware running open-source software and was advertised as world’s first $9 computer as a direct competitor to the RaspberryPi . The device boasted the following configuration:

  • 1 GHz R8M/R8 (ARMv7)SoC processor
  • 512 MB DDR3 SDRAM
  • Built-in Wi-Fi 802.11b/g/n, Bluetooth 4.0
  • One USB host with type-A receptacle, one USB On-The-Go port
  • Composite video and stereo audio port via mini TRRS
  • Optional composite TRRS to RCA audio-video cable
  • Optional VGA adapter and HDMI adapter (I got both)
  • Up to 45 GPIO ports
  • Supports 1-Wire and I2C protocols, PWM output
  • Serial console and Ethernet via USB for quick headless operation
  • Power options include 5V via USB OTG, 5V via CHN pin, and by 3.7V battery
  • Onboard NAND storage, 4-8GB

The PocketChip was a handheld with a 4.3 inch 480×272 pixel resistive touchscreen, a clicky keyboard, GPIO headers on the top of the device, and GPIO soldering pads inside of the injection molded case powered by the CHIP processor. It looks clunky but is easier to connect to the device and setup using the PocketChip rather than doing it with just the CHIP.

Unfortunately the company shutdown in 2018 due to various issues. However, I was one of the lucky backers to receive the devices but once I received them I put them in a drawer and kind of forgot about them as life got busy and interesting. Over the years I did try to power on the device a couple of times but never really looked into getting it to work, so they just collected dust in my desk (literally).

Over the past weekend I decided to try getting it to work so I did some searching and with a lot of trial and error finally managed to get things to work and boot into a working OS. 🙂 The main issue was that I was expecting it to work like the RaspberryPi where the OS was installed on an SD card but in this case the OS had to be flashed on to the onboard flash chip which was a bit more complicated process than installing to a SD card. I followed the instructions at NextThingCo Pocket C.H.I.P. Flashing Guide amongst other pages to get things to work. Here I will document some of the other things I had to do to get it to work. Please note that this was on a Debian setup, things might be a bit different for other OS’s

Install the Prerequisites

First we need to install the tools required by running the following command as root:

apt-get install git android-tools-fastboot sunxi-tools u-boot-tools

Download the CHIP SDK

Download the from one of the following links:

Download and extract the CHIP Tools

Download from one of the following sites:

Download CHIP OS Images

Download the CHIP OS image from one of the following links:


When I tried extracting the contents of the zip file I got from the first link, I got an error that the file is not a Zip file. After a lot of searching I found out that you can run the following command to extract the file instead:

jar xfv

Since that seems unnecessarily complicated. I have extracted and re-compressed the file and shared it at the second link. You can extract it using the standard zip tools.

Fix fastboot

The version of fastboot in the Debian repositories is newer than the one used in the setup scripts and if you try to flash with the version installed then fails with the following error message:

== Cached UBI located ==
Image Name:   flash server
Created:      Sun Aug 20 19:29:14 2023

Load Address: 00000000
Entry Point:  00000000
   Image 0: 1776 Bytes = 1.73 KiB = 0.00 MiB

.fastboot: invalid option -- 'i'
.fastboot: invalid option -- 'i'
.fastboot: invalid option -- 'i'
.fastboot: invalid option -- 'i'
.fastboot: invalid option -- 'i'

The easiest fix for this is to rollback to a previous version of the software that supports the -i parameter. You can try to search and download the older version from Debian’s repositories, but I found it easier to download the software from (as I was too tired to go search for it in the archives)

Once you download the file and extract the contents, follow these steps to rollback to the previous version of fastboot:

  • Backup the existing binary for fastboot
  • mv /usr/lib/android-sdk/platform-tools/fastboot /usr/lib/android-sdk/platform-tools/fastboot_old
  • Copy the extracted file from the zip file to the correct location
  • mv platform-tools/fastboot /usr/lib/android-sdk/platform-tools/fastboot

Put the CHIP in FEL mode

The FEL mode allows the software to flash the CHIP with a new firmware. This can be done by putting a jumper wire between GND and FEL. It will look something like the following:

Connecting a jumper wire between GND and FEL to enter FEL Mode

Once you have entered the FEL mode, connect the CHIP to the computer using the microUSB port on the CHIP, not the fullsize USB port.

Flashing the OS to CHIP

Once you have downloaded all the files and unziped them. Follow these steps to Flash the OS to CHIP.

  • Move the CHIP-tools directory to the CHIP-SDK directory
  • mv CHIP-tools CHIP-SDK/
  • Select the Image you want to install and move it into the CHIP-SDK directory. There are 8 Images to choose from, I tested with the testing-server-b543 and testing-pocketchip-b667 images as I have 2 CHIPS to play with. 🙂
  • The original instructions on the site ask you to run the ./ script located in the CHIP-SDK directory but it failed most commands on my system. I think that you should be able to proceed without running it but haven’t tried it.
  • Switch to the CHIP-tools directory
  • cd CHIP-SDK/CHIP-tools
  • Run the firmware upgrade script, replacing Path/To/Chip/Image with the location where you extracted the Image you want to install
  • ./ -L ../../flash-collection/testing-server-b543/

    If you have done everything correctly and nothing is broken, you will get an output similar to the following:

    CHIP is ready to roll!

    If you see the message that “FLASH VERIFICATION COMPLETE.” and that “CHIP is ready to roll!”, then the OS installation has completed successfully. Now you can disconnect the CHIP from the computer and remove the jumper cable.

    Booting into CHIP

    If you have the PocketCHIP, then you can just power up the device by pressing on the power button for a second (pressing it for 10 seconds shuts it down forcefully). If you just have the CHIP, you will need to connect it to a monitor and connect a keyboard as well. (I used the PocketCHIP to configure everything and then used it separately).

    The boot up process can take a minute or two, and assuming everything went well you should see the standard boot messages on the screen. Once you get to the login prompt you can log in using the username ‘chip’ (without the quotes) and ‘chip’ (without the quotes) as the password. The root account password is also ‘chip’ (without the quotes).

    Connecting to WiFi and configuring the CHIP

    The first thing that you should do now is connect the device to a WiFi network so that you can SSH into it for ease of configuration. The second thing should be to change the default passwords 🙂

    The easiest way to configure WiFi is to use the nmcli tool. Run the following command as root to connect to the WiFi. More details on the command are available at How to Connect Wi-Fi from Linux Terminal Using Nmcli Command

    nmcli dev wifi connect <SSID of The Network to Connect With> password <password for the Wifi Network> 

    Once the device is connected to the WiFi, get your IP address using the following command:

    ip address

    Then you can SSH into the device from any system using the IP address.

    CHIP is working!!!

    Running Debian 8 Testing

    Running the PocketCHIP customized version (Debian 8)

    Updating the OS to the latest version

    The system is running Debian 8 by default and you should upgrade it to the latest version. Unfortunately, I keep getting errors when I try to upgrade to the latest Debian version and haven’t yet fixed the problem. Basically, I think you need to update the /etc/apt/sources.list with the correct mirror details and then upgrade. Once I get some time to revisit the setup and resolve the issue I will post the fix on the blog as a followup post to this one.

Workaround for paste not working in Whatsapp web on Firefox

Filed under: Computer Software,Knowledgebase — Suramya @ 10:40 PM

In the latest version of Firefox (116.0.3) something changed and due to this if you are using the Web version of Whatsapp you are no longer able to paste anything into the chat window. Ctrl-V, Right-Click -> Paste, nothing works. The issue exists on both Windows and Linux builds of Firefox. Did a search and found that others are facing the same issue and found a work around at Firefox doesn’t allow to paste into WhatsApp web anymore?

In order to fix follow these steps:

  • Go to about:config
  • Search for ‘dom.event.clipboardevents.enabled’ (without the quotes)
  • Set the value to false by double clicking on the entry

The change takes effect immediately. This is not a permanent fix and once Firefox fixes the issue you should revert the change.

ChatGPT is not an all powerful AI it can’t even perform simple multiplications

Filed under: Artificial Intelligence — Suramya @ 9:49 PM

In my previous post I was talking about how I am usually quite skeptical of the claims being made about AI and how it is going to solve the world’s problems. There are some good usecases and there are some advantages to adding Machine Learning to the system. I have written about a few of them here.

But we are nowhere close to the Singularity and most of the folks who are pushing AI right now are the same ones who where pushing NFT’s earlier and Crypto before that… Case in point, according to founder of AI is an existential threat and OpenAI ChatGPT is a showcase of how advanced AI has become. However, this ‘advanced’ AI can’t even multiply two numbers to get the correct answer. I asked ‘What is 7467*5730’ and it gave me ‘42,777,810’. Then I asked my calculator to perform the same multiplication and that gave me: (Drum roll please…) 42,785,910. (See the screenshots below)

ChatGPT can’t perform a simple multiplication

Others have faced the same issue and I rest my case about why we need to be very careful using these AI assistants because they give answers that look legitimate and correct but are completely wrong or have subtle errors that need expertise to identify.

The Judge by GoblinTools is a great tool to tell how written text comes across qualitatively

Readers of this blog (and those who know me) know that I am usually quite skeptical of tools that claim to judge the emotional content of text or tell how the text comes across qualitatively. However, this new site called The Judge – Goblin Tools is quite impressive. As per James over on Mastodon, the tool was created to help neurodivergent folks communicate better with the normals avoiding misunderstanding, bad assumptions about intent, etc.

I tested it out with content from my blog and I have to say that it summarized the tone and content quite nicely. For example below is the summary it gave for my post on Celebrating India’s 76th Independence day!

Emotionally, this text comes across as proud, patriotic, and reflective. It begins by acknowledging and celebrating India’s 76th Independence Day, recognizing the significance of gaining freedom from British rule. It highlights the sacrifices, bloodshed, and tears endured by many individuals who fought for India’s freedom, emphasizing that not all their names are known and that this is a tragic aspect. The text expresses a sense of frustration with the tendency to focus solely on iconic figures like Gandhi and Nehru, disregarding the efforts of numerous other freedom fighters.

As the text looks towards the future, there is a strong emotional undertone of remembrance and gratitude towards those who paved the way for freedom. It cites famous slogans from freedom fighters, adding a sense of inspiration and reverence for their contribution. The passage acknowledges the importance of remembering the sacrifices made by past generations for the betterment of the nation.

There is a shift in emotion when it proudly proclaims India’s progress and achievements in various fields, such as technology, space exploration, and healthcare. It displays a sense of national pride and triumph over past perceptions that diminished India’s image. The text mentions India’s relief efforts during the COVID-19 pandemic and positions India as a nation capable of compassionate and humanitarian actions.

Moving forward, the text acknowledges areas that still require improvement, alluding to societal customs and mindsets. It expresses a desire for growth and change while also highlighting the need for self-reflection in other countries that criticize India, pointing out their own flaws and challenges.

The passage concludes with a message of unity and inclusivity, promoting the idea that humanity should transcend differences in caste, religion, nationality, sexuality, and age. It embraces the concept of a global family and emphasizes the values of humanity and national loyalty.

Overall, this text conveys a mixture of pride in India’s accomplishments, gratitude for the sacrifices made by freedom fighters, and a sense of reflection on the challenges that still exist. It aims to inspire unity, progress, and a commitment to the values that define the nation.

It did manage to capture the exact tone I was going for so that is quite nice. According to their About Us page, the site uses AI technologies in the backend including OpenAI’s models. They are planning to move to open source alternatives as and when they become available and reliable. Keeping that in mind, I would not recommend using this to analyze any text that has private or confidential information because it might be used to train OpenAI’s models. That being said I would be keeping an eye on this software and once they go to an opensource model and allow us to run a local instance of the tool I certainly wouldn’t mind using as part of my writing toolkit.

Yes, It is absolutely fine to code (or work) ‘just for the money’

Filed under: My Thoughts — Suramya @ 10:16 PM

Once again we are seeing a flurry of messages on various social media sites talking about coding for money. My feed on Mastodon had a few folks post screenshots from other sites with some inspired takes and I especially love the one below (and the response):

Yes, It’s ok to code for money.

These pseudo-intellectuals who have never faced the possibility of not having enough money, mostly because they were born rich or managed to luck into a job that gives them enough money have the guts to tell people that it is not ok to code for money. They have the financial cushion to decide that they will do something for free but not everyone has that option. This is the same nonsense the artists have been getting for years now that you should paint/write/create for passion and not for money. They are told by folks who have money that if you are poor and suffering then your art is more ‘pure’. Personally I think it is just an excuse not to pay the artists.

This attitude is a leftover from the colonial thinking where it was considered crass / common for the nobility to work for a living and working was something that only the common folks did. There have been numerous documented instances where folks were actually disowned by their family because they actually worked for their living or ran a business. This was called Dérogeance and included engagement in certain professions and occupations considered to be “lowly”. In particular, it prevented the nobility from engaging in commerce and retail trade.

I love computers and am lucky that I get to work on something that is my passion. However, I know enough people in the industry who don’t like computers and are in it for the money and Guess what? that is perfectly ok. I remember in school I had a classmate who hated programming but was planning to do a degree in Computer Science. So I asked him why he was doing that even though he hated coding, and he responded saying that is where the money is. At the time we made fun of him but now that I think of it, he made money and once he was comfortably settled he switched roles and has moved on to something they enjoy doing. It is perfectly fine not to want to come home from work and start coding away on a personal project.

Long story short, telling people that it is not ok to do things ‘just for the money’ is extremely classicist / rude and frankly it is none of your business why anyone is in the industry. You are not the gatekeeper for the industry and can just buzz off…

ISRO’s Chandrayaan-3 successfully completed its Fifth and final orbit reduction maneuver

Filed under: Astronomy / Space — Suramya @ 6:57 PM

Chandrayaan-3 is the third spacecraft sent to the moon by the Indian Space Research Organisation (ISRO) and the second one to attempt a soft landing on the far side of the moon. The Chandrayaan-3 consists of a lander module (LM), a propulsion module (PM) and a rover. Earlier today the craft successfully completed its 5th firing that has put the Chandrayaan-3 into an orbit of 153 km x 163 km around the moon as intended bringing it another step closer to its moon landing attempt which is expected to happen at 5.47 p.m on August 23rd 2023.

Chandrayaan-3’s Moon-bound maneuvers

After the completion of the five orbit reduction maneuvers ISRO said that it is gearing up for the next most crucial operations which is scheduled on August 17.

“It’s time for preparations as the Propulsion Module and the Lander Module gear up for their separate journeys. Separation of the Lander Module from the Propulsion Module is planned for August 17, 2023,” the space agency said

The propulsion module will separate from the lander while in orbit.

Following that, a series of complex braking maneuvers will be executed to facilitate a soft landing in the South Polar region of the Moon on August 23. The lander is expected to touch down on the moon surface at 5.47 p.m.

I am eagerly waiting for this attempt with fingers crossed. Although I think that the mission would have been even better if it was landing on the moon on 15th Aug (India’s Independence Day). More details on the mission and the craft is available over at the IRSO’s Chandrayaan-3 site.
