Adenitis

What is Adenitis?

Adenitis refers to the inflammation of lymph glands present in our body. Lymph nodes are present everywhere in human body. The main symptoms of adenitis are pain and swelling. Adenoids of different body parts are given different names depending upon their location. Inflammation from one part may reach to other parts of the body. Mainly bacteria or virus is responsible for producing the infection. When inflammation is not diagnosed at an early stage it may further develop and grow into a tumour. Generally, on conventional system surgery is done to remove the tumour of the affected part of the body. But this is not a real cure but inflammation can occur repeatedly.

TL;DR: Migrating my website from Drupal 7 to Hugo

Initial website

Looking back at my website’s history, the domain was first registered sometime in 2003. Back then, it was mostly a couple of html pages. Being (and still) a novice in web, my website was mostly on ideas from others. IIRC, for the bare html one, I took a lot of look wise details from Miss Garrels’ website.

sg3-utils, version 1.44, was recently uploaded to Debian. This new upstream release has happened almost 2.5 years after the last release. One important feature to emphasize about is some support for NVMe disks, which are now getting more common on latest range of laptops.

What a way to make a gift!

I’m pleased to announce the 1.72 release of Laptop Mode Tools. Major changes include the port of the GUI configuration utility to Python 3 and PyQt5. Some tweaks, fixes and enhancements in current modules. Extending {black,white}list of devices to types other than USB. Listing of devices by their devtype attribute.

A filtered list of changes is mentioned below. For the full log, please refer to the git repository.

It is interesting how a user-space task could lead to hinder a Linux kernel software suspend operation.

What is apt-offline

Description: offline APT package manager
 apt-offline is an Offline APT Package Manager.
 .
 apt-offline can fully update and upgrade an APT based distribution without
 connecting to the network, all of it transparent to APT.
 .
 apt-offline can be used to generate a signature on a machine (with no network).
 This signature contains all download information required for the APT database
 system. This signature file can be used on another machine connected to the
 internet (which need not be a Debian box and can even be running windows) to
 download the updates.
 The downloaded data will contain all updates in a format understood by APT and
 this data can be used by apt-offline to update the non-networked machine.
 .
 apt-offline can also fetch bug reports and make them available offline.

I am pleased to announce the release of apt-offline , version 1.8.0. This release is mainly a forward port of apt-offline to Python 3 and PyQt5. There are some glitches related to Python 3 and PyQt5, but overall the CLI interface works fine. Other than the porting, there’s also an important bug fixed, related to memory leak when using the MIME library. And then there’s some updates to the documentation (user examples) based on feedback from users.

PSA: Research in the domain of Ayurveda

http://www.patanjaliresearchfoundation.com/patanjali/

I am so glad to see this initiative taken by the Patanjali group. This is a great stepping stone in the health and wellness domain.

So far, Allopathy has been blunt in discarding alternate medicine practices, without much solid justification. The only, repetitive, response I’ve heard is “lack of research”. This initiative definitely is a great step in that regard.

Ayurveda (Ancient Hindu art of healing) has a huge potential to touch lives. For the Indian sub-continent, this has the potential of a blessing.

This has gotten me finally ask the question

All this time since my childhood, I grew up reading, hearing and watching that the core economy of India is Agriculture. And that it needs the highest bracket in the budgets of the country. It still applies today. Every budget has special waivers for the agriculture sector, typically in hundreds of thousands of crores in India Rupees. The most recent to mention is INR 27420 Crores waived off for just a single state (Uttar Pradesh), as was promised by the winning party during their campaign.

Bugs can be annoying. Especially the ones that crash or hang and do not have a root cause. A good example of such annoyance can be kernel bugs, where a faulty hardware/device driver hinders the kernel’s suspend/resume process. Because, as a user, while in the middle of your work, you suspend your machine hoping to resume your work, back when at your destination. But, during suspend, or during resume, randomly the bug triggers leaving you with no choice but a hardware reset. Ultimately, resulting in you losing the entire work state you were in.
