RIP: MOOC materials; the coronavirus effect

Coronavirus (Covid 19 caused by SARS-CoV-2) pandemic and lockdown disrupted lives and market in a completely unexpected manner. One market that seen a spike during lockdown is MOOC and online education.

What I realized of late is that many of these MOOC materials are not suitable for remote viewing. I have taken a couple of courses in random pseudonyms in Coursera and also another one in my real name in PadhAI conducted by IIT faculties. Most of these materials were recorded in a way as if they teach in physical classrooms. Because of that reason, they're very tiring to watch; they lack some basic video editing. Compare that to animated education videos posted to YouTube.

One exception to this MOOC material is MIT 6.S191: Introduction to Deep Learning (I'm yet to watch them all though)

Classical teaching jobs are in danger

These days schools are starting up online classes that follow materials similar to these MOOCs. Students are finding hard to follow them as they're used to YouTube videos. So, based on feedback, schools started to switch to a readymade library of videos. This in turn poses danger to many teaching jobs.

Converting PSD with PHP/ImageMagick

After seeing feature rich options in Imagick PECL extension at Mikko Koppanen 's (the author) website and also impressed with ImageMagick 's features, I have decided to use it for the PSD to XHTML conversion website that I'm architecting and managing. Since, the team wants programming help for converting PSD images, I have tried it (documentation is sparse on PSD handling) Converting PSD to PNG/JPEG/etc Note that, flattenImages() is needed for layered/multi-page PSD file. <?php $im = new Imagick('test.psd'); $im->flattenImages(); $im->setImageFormat('png'); $im->writeImage('test.png'); ?> Extracting PSD layers One by one <?php $im = new Imagick('test.psd'); $im->setImageFormat('png'); for ($i = 0, $num_layers = $im->getNumberImages(); $i $im->setImageIndex($i); $im->writeImage('layer' . $i . '.png'); } ?> Note that, there is a better version below In a single call with writeIm...

Malayalis may not have valued Nedumudi Venu, but ChatGPT did

Back in the late 1980s (exactly in 1988, according to some searches)—there was a much-loved Malayalam serial called Mandan Kunju . Ever since then, our family developed a deep appreciation for Nedumudi Venu. His acting was often compared to that of Sivaji Ganesan, who was widely celebrated at the time. There were even debates about how Nedumudi was surpassing Sivaji with his unmatched natural style. Even in his 30s, Nedumudi would appear with grey hair, convincingly portraying elderly characters. About 35 years ago, I happened to watch a film in which Nedumudi Venu actually played the lead role—something quite rare in his career. I couldn’t remember the plot or the supporting cast, but what stayed with me vividly was the setting. The film had been shot in Munnar’s Madupetty Estate, with the estate school serving as one of the locations. I also remembered a Carnatic-influenced song filmed outdoors in the estate, which left a strong impression on me. For years, I tried to rediscover ...

Humble Award - Dr. A.N. Sreevatsan

Dr. A.N. Sreevatsan , ENT specialist located in Adyar, Chennai is one of the gems available in medicines. No assistants in his consulting room and he'd take at least 15mins for every patients. So far I have referred many and all are happy with his approach. Every wannabe doctor should visit him personally to understand his approach. I wish him to be more famous than now.
