Most of the time we work with JPEG images because that is the most common format for digital images. They have the virtue of decent quality combined with smaller file size, and so won't fill up your storage quite as fast. But if you want the highest quality you have to work with unprocessed images, called RAW images. These are simply the actual data recorded by the camera sensors, and they give you some advantages, such as better correction of white balance. But GIMP does not open RAW images directly. But there are some work-arounds which we discuss in this tutorial.

What is PINN (PINN Is Not NOOBS)?

An easy enhanced Operating System installer for the Raspberry Pi

The latest version of PINN can be downloaded from sourceforge.

This README relates to v3.8

(PINN-lite does not include any operating systems at all.

It is more akin to NOOBS-lite rather than NOOBS. For that reason, the filename that you download is called pinn-lite.zip. More recently, pinn.zip has also been made available for download which includes versions of Raspbian and LibreELEC.)

In this episode our two hosts talk to an eclectic panel consisting of

members of the Georgian affiliation of the Electronic Frontier Foundation

(EFF) called Electronic Frontiers Georgia. Among other topics, civil rights

(especially in the digital age), sharing of ideas never mind other

intellectual capital and why this still matters in socialist America are the

focus of discussion. Plus Chris manages to recount most of the founding

fathers of the US (gaps may be present... :-)

Hi, I'm Sarah. In this show, I introduce myself and ramble about how I got into tech. Despite saying I hate talking about myself, I managed 7 minutes and 25 seconds. I started as a kid with a Tandy and eventually ended up being a librarian and a sysadmin for a RedHat system.

Knightwise gives us a good first impression of the Ubuntu 22.04 release and answers the question if its ready for prime time. We go down a little rabbithole on why there will never be a year of the Linux desktop.

The app mentioned to Sync Onedrive with Ubuntu is Insync: https://www.insynchq.com

Introduction

Hosts:

MrX

Dave Morriss

We recorded this on Sunday March 6th 2022. The last time we set up a chat like this was back in March 2021, almost exactly a year ago surprisingly!

Note on the title: we spoke a little on the subject of the Scots language in the show - when speaking of the current census - so the title uses a Scots term.

Topics discussed

COVID:

Losing track of time

Christmas:

A quiet time for both of the hosts, with some family time

Dave’s family matters:

Son graduated after doing an MSc and got a job quite quickly last year

Daughter had graduated from an MSc the year before and also got a job this year.

Dave had a bout of shingles in early January, which lasted about 6-7 weeks overall. If you can get a shingles vaccination as you age, get one!

UK heating, boilers, etc.

MrX’s in-laws had a boiler failure during the cold weather, and a gas leak!

Dave had a leak in his cold water tank in the attic which flooded the room below. He decided to completely upgrade the heating system, remove all tanks and put in a new pressurised condensing gas boiler. See the Wikipedia page for an overview of central heating systems.

Old-style plumbing; coal fires, back boilers and dampers.

The era of coal:

Gas poker used for starting domestic (usually coal) fires

Coal gas made from coal, superseded by natural gas

Gasometer storage device for coal gas

Internet connectivity:

Dave has transitioned from ADSL to fibre since the last show

Fibre to the Premises, with up to 1 Gbit/s if desired

New router using Wireless 6

MrX has Fibre to the Cabinet

Dave’s new router doesn’t allow the Pi-hole to work at the moment

Chromebook:

MrX has acquired a Chromebook since our last show

It is convenient to use. Made answering the online Scottish Census quite straightforward.

Census and Scots Language:

The Census asks about the Scots Language, whether the person can speak and understand it.

Dave follows @lenniesaurus on Twitter who introduces a daily Scots word.

According to Wikipedia:

Scots is recognised as an indigenous language of Scotland, a regional or minority language of Europe, and a vulnerable language by UNESCO. In the 2011 Scottish Census, over 1.5 million people in Scotland reported being able to speak Scots.

NVMe SSDs: Everything you need to know about this insanely fast storage

NVM Express (NVMe) or Non-Volatile Memory Host Controller Interface Specification (NVMHCIS) is an open, logical-device interface specification for accessing a computer's non-volatile storage media usually attached via PCI Express (PCIe) bus. The acronym NVM stands for non-volatile memory, which is often NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCI Express (PCIe) add-in cards, and M.2 cards, the successor to mSATA cards. NVM Express, as a logical-device interface, has been designed to capitalize on the low latency and internal parallelism of solid-state storage devices

Discussing the interesting oddity that is the meatball; its origins, and some misconceptions and coincidences surrounding the tasty "traditional" dish of spaghetti and meatballs.

Historical context and explanations were provided by the article "Is Spaghetti and Meatballs Italian?" by Shaylyn Esposito, published in Smithsonian Magazine.
