g-io-error-quark 39 error when stopping dbus-service

When I restart a particular computer there is an error message,

# init 6
Error getting authority: Error initializing authority: Could not connect: Connection refused (g-io-error-quark, 39)

I found out that this is caused by the dbus service. I can cause the error message to appear by

# systemctl stop dbus.service
Error getting authority: Error initializing authority: Could not connect: Connection refused (g-io-error-quark, 39)

This was all done in a root shell, naturally. Does anyone know what this means, and how to fix it? I find that d-bus seems to be little documented (or too complicated for me, or both). The machine is running CentOS Linux release 7.2.1511 and is up to date.

For me it happened after RHEL 7.4 -> 7.5 upgrade. Dbus socket got moved to /run/dbus/system_bus_socket. Even though systemd clearly points to /run/dbus/system_bus_socket it’s still wants to connect via /var/run/dbus/system_bus_socket “` [root@ipsystem]# systemctl restart systemd-logind.service Error getting authority: Error initializing authority: Could not connect: Connection refused (g-io-error-quark, 39)

Notice it’s connecting to /run/dbus/ socket

Is McDonald’s MacCoin a cryptocurrency? Restaurant chain to launch the ‘currency’ soon

The popular restaurant chain, McDonald’s unveiled MacCoin on Sunday, shocking the business world. While a lot of media outlets claimed it to be a cryptocurrency but it’s not. A few months back, Kodak announced that it’s coming with its own cryptocurrency and McDonald’s appeared to be similar especially because, they described MacCoin as the “first fully food-backed global currency”.

As a Fortune report said,” it’s not a Bitcoin alternative.” In fact, it is just a coupon or voucher ‘heavier-than-usual’ for a free burger. Reportedly, McDonald’s is giving out the tokens in 50 countries, at 14,000 restaurants starting from August 2. This step has been taken to commemorate 50th anniversary of the Big Mac.

Researchers discover new geometric shape dubbed “scutoid”

A group of researchers has discovered a previously undescribed shape they have called a “scutoid” through modeling and experiments. This shape is specifically adopted by packed epithelial cells during embryonic development. The new shape could lead to advancements in tissue engineering according to the team.

As an embryo develops tissue is bent into the complex three-dimensional shape, and the tissues eventually turn into organs. The cells are packed very tightly at this stage and to accommodate the curving that happens during embryonic development scientists discovered with further research that the epithelial cells at this stage adopt a shape that was previously undescribed…

Tsundoku: The art of buying books and never reading them

Do you have a habit of picking up books that you never quite get around to reading?
If this sounds like you, you might be unwittingly engaging in tsundoku – a Japanese term used to describe a person who owns a lot of unread literature.

Prof Andrew Gerstle teaches pre-modern Japanese texts at the University of London.
He explained to the BBC the term might be older than you think – it can be found in print as early as 1879, meaning it was likely in use before that.
The word “doku” can be used as a verb to mean “reading”. According to Prof Gerstle, the “tsun” in “tsundoku” originates in “tsumu” – a word meaning “to pile up”…

Google Releases Data Blending in Google Data Studio

Combine Different Data Sources Within a Single Chart

“Data Studio is Google’s very powerful data visualisation tool which is great for bringing together data from multiple sources and presenting it in a highly visual and accessible way. With the introduction of data blending, it now allows even more flexibility by enabling you to combine multiple data sources directly in the Data Studio UI and visualising your results in a single chart.”

This capability allows you to draw on your favourite data sources such as Google Ads and Google Analytics and join them together with each other or third-party data sources via a common set of dimensions. Previously it was only possible to have one data source per graph or table but now Google allows you to merge up to five different sources of data within a single graph / table …

Facebook, Google and more unite to let you transfer data between apps – TechCrunch

The Data Transfer Project is a new team-up between tech giants to let you move your content, contacts, and more across apps. Founded by Facebook, Google, Twitter, and Microsoft, the DTP today revealed its plans for an open source data portability platform any online service can join. While many companies already let you download your information, that’s not very helpful if you can’t easily upload and use it elsewhere — whether you want to evacuate a social network you hate, back up your data somewhere different, or bring your digital identity along when you try a new app. The DTP’s tool isn’t ready for use yet, but the group today laid out a white paper for how it will work…
