I recently switched what I spend the majority of my professional life doing: history -> software engineering. I'm currently working as an ML Engineer @zenml_io and really enjoying this new world of #MLOps, filled as it is with challenges and opportunities.

 I wanted to get some context for the wider work of a data scientist to help me appreciate the problem we are trying to address @zenml_io, so looked around for a juicy machine learning problem to work on as a longer project.
I was also encouraged by @jeremyphoward's advice to "build one project and make it great" (https://t.co/Doo88EUhkN). This approach seems like it has really paid off for those who've studied the @fastdotai course and I wanted to really go deep on something myself.
Following some previous success working with @adyantalamadhya and another mentor via @SharpestMindsAI on a previous project, I settled on computer vision and was lucky to find @ai_fast_track to mentor me through the work. (We meet a couple of times per week).
In the last 6 weeks, I've made what feels like good progress on the problem. This image offers an overview of the pieces I've been working on, to the point where the 'solution' to my original problem feels on the verge of being practically within reach.
After just a few lessons of the @fastai course, I trained a classification model to ~95% accuracy to help me sort redacted images from unredacted images.
https://t.co/E0WY4xYnlZ
I used @explosion_ai's Prodigy tool to annotate an initial round of data to pass into the next step, enjoying how the labelling process brought me into greater contact with the dataset along the way.
https://t.co/bNd9mx7FHv
I switched to using IceVision (co-created by @ai_fast_track) to help me with the more complicated object detection problem, using MMDetection and VFNet to get pretty good results early on.
https://t.co/EZ3cdkF8I8
I'm currently in the process of creating my own synthetic images to boost the annotations I've manually made. (I'll be writing about this process soon as well, as I'm learning a lot about why this is so important for these kinds of computer vision problems.)
I've also been amazed at the effectiveness of self-training (i.e. using my initial model in my annotation loop to generate an initial set of annotations which I can easily amend as appropriate, then feeding those annotations in to create a better model etc). More to follow...
I started using @EvidentlyAI to do drift detection, inspired by work I was doing for @zenml_io to add it as an integration. This helped me think about how new data was affecting the model and the training cycle. There's a lot of depth here, and am looking forward to diving in.
I made a tiny little demo on @huggingface Spaces to show off the current inference capabilities. This is a simple @Gradio app but I liked how easy this was to put together (a couple of hours, mainly involving some build issues and a dodgy `requirements.txt` file)
Along the way, I found it sometimes quite painful or fiddly to handle the PDF files that are the main data source for the project, so I built my own Python package to handle the hard work. https://t.co/bghhYDgKOz
I used @fastdotai's nbdev to very quickly get the starters of what I'm hoping might be a useful tool for others using PDF data for ML projects.
https://t.co/aZaTgOUu33
Throughout all this, @ai_fast_track has been patiently helping guide me forward. He saved me from going down some dark rabbit holes, from spending too long studying skills and parts of the problem that needed relatively little mastery in order to get to where I am.
Farid (@ai_fast_track) has been a consistently enthusiastic and kind advocate for my work, moreover, and this has really helped me stay the course for this project that takes a decent chunk of my time (esp seeing as I do it completely aside / separately from my day job).
I feel like I'm consistently making progress and learning the skills of someone working in computer vision, even though I have so much left to learn! My project still has a ways to go before it's 'done', but I'm confident that I'll get there with @ai_fast_track's support. /end

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.

https://t.co/FBfXhUrH5d


Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.


...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.


Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.

🌺श्री गरुड़ पुराण - संक्षिप्त वर्णन🌺

हिन्दु धर्म के 18 पुराणों में से एक गरुड़ पुराण का हिन्दु धर्म में बड़ा महत्व है। गरुड़ पुराण में मृत्यु के बाद सद्गती की व्याख्या मिलती है। इस पुराण के अधिष्ठातृ देव भगवान विष्णु हैं, इसलिए ये वैष्णव पुराण है।


गरुड़ पुराण के अनुसार हमारे कर्मों का फल हमें हमारे जीवन-काल में तो मिलता ही है परंतु मृत्यु के बाद भी अच्छे बुरे कार्यों का उनके अनुसार फल मिलता है। इस कारण इस पुराण में निहित ज्ञान को प्राप्त करने के लिए घर के किसी सदस्य की मृत्यु के बाद का समय निर्धारित किया गया है...

..ताकि उस समय हम जीवन-मरण से जुड़े सभी सत्य जान सकें और मृत्यु के कारण बिछडने वाले सदस्य का दुख कम हो सके।
गरुड़ पुराण में विष्णु की भक्ति व अवतारों का विस्तार से उसी प्रकार वर्णन मिलता है जिस प्रकार भगवत पुराण में।आरम्भ में मनु से सृष्टि की उत्पत्ति,ध्रुव चरित्र की कथा मिलती है।


तदुपरांत सुर्य व चंद्र ग्रहों के मंत्र, शिव-पार्वती मंत्र,इन्द्र सम्बंधित मंत्र,सरस्वती मंत्र और नौ शक्तियों के बारे में विस्तार से बताया गया है।
इस पुराण में उन्नीस हज़ार श्लोक बताए जाते हैं और इसे दो भागों में कहा जाता है।
प्रथम भाग में विष्णुभक्ति और पूजा विधियों का उल्लेख है।

मृत्यु के उपरांत गरुड़ पुराण के श्रवण का प्रावधान है ।
पुराण के द्वितीय भाग में 'प्रेतकल्प' का विस्तार से वर्णन और नरकों में जीव के पड़ने का वृत्तांत मिलता है। मरने के बाद मनुष्य की क्या गति होती है, उसका किस प्रकार की योनियों में जन्म होता है, प्रेत योनि से मुक्ति के उपाय...

RANI NAIKI DEVI AND THE BATTLE OF KASAHRADA

Mohammad Ghori, the young Ghurid Prince conquered Ghaznavids in Afghanistan in the year 1173 CE. He conducted some successful raids into the Indian territory, which even Mahmud Ghazni & the Persians couldn't do.


First&foremost,Ghori invaded states of Multan &Uch in India.After this he turned to southern states of Gujarat &Rajputana.Everybody knows this about Ghori,but what most pple r unaware of is the defeat he suffered at hands of Chalukyan Queen Naiki Devi in 1178 Battle of Kasahrada.


When he marched southwards, his first target was the prosperous fortified town of Anhilwara Patan.
It was the capital of Chalukyas(also known as Solankis of Gujarat) which was established by Vanraj of Chapotkata Dynasty in 8th century.


American historian Tertius Chandler states that it was the 10th largest city in the world at that time. The history of Chalukyas has been written by many historians, but the valour of the Great Queen Naiki Devi remains unsung.


Born to the Kadamba King Paramardin of Goa,Naiki Devi was well trained in sword fighting, horse riding, strategy & every other subject of Statesmanship. She was married to King Ajaypala of Gujarat who sat on throne in 1171CE. Unfortunately,the King died within 4 yrs of his rule.

RT-PCR corona (test) scam

Symptomatic people are tested for one and only one respiratory virus. This means that other acute respiratory infections are reclassified as


2/12

It is tested exquisitely with a hypersensitive non-specific RT-PCR test / Ct >35 (>30 is nonsense, >35 is madness), without considering Ct and clinical context. This means that more acute respiratory infections are reclassified as


3/12

The Drosten RT-PCR test is fabricated in a way that each country and laboratory perform it differently at too high Ct and that the high rate of false positives increases massively due to cross-reaction with other (corona) viruses in the "flu


4/12

Even asymptomatic, previously called healthy, people are tested (en masse) in this way, although there is no epidemiologically relevant asymptomatic transmission. This means that even healthy people are declared as COVID


5/12

Deaths within 28 days after a positive RT-PCR test from whatever cause are designated as deaths WITH COVID. This means that other causes of death are reclassified as

SRI CHAMPAKADHAMA SWAMY, BANNERGHATTA HILL, BENGALURU (KAR)
#bharatmandir

The shrine is dedicated to Sri Vishnu along with Devi Lakshmi and Bhoodevi.
It is built in an area full of Champaka trees.
As champaka flowers are offered to Sri Vishnu here, it is called Champakadhama.


It is believed that King Janmejaya had sarpa-dosha. To get rid of it, he took bath in the nearby pond. He emerged with a golden body and sarpa-dosha was also removed. The pond is called Swarnamukhi and believed to have curative powers.
Sri Vishnu murti was consecrated by him.


It is also believed that this forest area was the Dandakaranya where Sri Ram stayed in exile.
Some believe that the original shrine was built by Pandavas.
The pushkarni/pond is emptied once a year so that the rock at the bottom (which has image of Anjaneya) may be worshipped.

Great article from @AsheSchow. I lived thru the 'Satanic Panic' of the 1980's/early 1990's asking myself "Has eveyrbody lost their GODDAMN MINDS?!"


The 3 big things that made the 1980's/early 1990's surreal for me.

1) Satanic Panic - satanism in the day cares ahhhh!

2) "Repressed memory" syndrome

3) Facilitated Communication [FC]

All 3 led to massive abuse.

"Therapists" -and I use the term to describe these quacks loosely - would hypnotize people & convince they they were 'reliving' past memories of Mom & Dad killing babies in Satanic rituals in the basement while they were growing up.

Other 'therapists' would badger kids until they invented stories about watching alligators eat babies dropped into a lake from a hot air balloon. Kids would deny anything happened for hours until the therapist 'broke through' and 'found' the 'truth'.

FC was a movement that started with the claim severely handicapped individuals were able to 'type' legible sentences & communicate if a 'helper' guided their hands over a keyboard.

So here is a secret: Not everything I write goes anywhere. I have at least 4 books completely written and edited that never went on submission. I have books that stalled out at 20k. I have docs on my computer with opening paragraphs I don't remember writing. But! 1/

Every now and then an idea sticks with me like that corner of tortilla chip that just won't go down your throat. It happened with SPARROWHAWK, which began as 40k of a YA story, died, and was reborn as a comic, thanks to @christopher_j_r and @boomstudios. And now... 2/

It's happening with THE WILLOWS, a short story that you'll see in @UncannyMagazine next year. This Southern Gothic horror story began as an attempt to sell my next Romance to @AbZurdity after the Blud books in 2014 or so. And she didn't buy it. Guess why? 3/

Turns out, it wasn't a Romance! It was Southern Gothic Horror. Even the bones of it screamed strangeness, not sexiness. I loved the taste of the world, but I hadn't found the right story yet. Tried to write it 2 more times and failed. Until I finally understood what it was. 4/

So I took the 50 pages I'd written and cut half of them, twisting the story around from a gothy Romance inspired by the band the Civil Wars and turned it into a spooky descent into madness. And it looked back at me from the abyss as if to say, DUH. Sometimes... 5/
