Kobo eReaders Software Features List: Apart from not reading Kindle format it actually has more features and mods than Kindles

Date Published: Sat, 10 Jul 2021 19:19:02 +0200

For the most part all Kobo ebook readers run the same software and have all the same features, with a few exceptions. For instance, the Kobo Forma and Kobo Elipsa are the only two models with official Dropbox support to transfer files wirelessly, and the older models don’t have OverDrive built-in but they still support library ebooks.

One of the advantages with Kobo ereaders is they are open to installing other ebook programs and custom patches and mods, and you can use Calibre to manage your ebook library and collections. Check the Kobo section at MobileRead for the latest developments. These will not be covered in this list; this list is for official Kobo features only.

List of supported formats for Kobo ereaders: KEPUB, EPUB, EPUB3, FlePub, PDF, MOBI, JPEG, GIF, PNG, BMP, TIFF, TXT, HTML, RTF, CBZ, CBR.

Imagine if Kobo was 'allowed' to read Kindle format ebooks from Amazon... it could be the end of Kindle, with some real competition. Calibre software though does wonders for finding ebooks and also 'converting' Kindle format to ePub.

Below is a list of all the main software features that Kobo ereaders support, including the notebook and writing features that are exclusive to the Kobo Elipsa. I’ve decided to use a new format for reviews. Since software features rarely change from one model to the next, I’m going to start focusing mostly on hardware […]

How South Africa's Eskom avoided more load-shedding this winter - Koeberg Nuclear Unit back online and Wind was contributing 500-1100MW

Date Published: Sat, 10 Jul 2021 19:16:28 +0200

In the last full week of load-shedding – between 7 June and 13 June – the average contribution of wind generation during peak evening usage stood at 525MW.

In the most recent week of 28 June to 4 July 2021, the figure was more than double that – at 1,272MW. The week before that, wind generation’s contribution averaged at 1,077MW during the evening peak.

Eskom currently has nearly 5,350MW of renewable generation capacity, including more than 2,700MW of installed capacity at independent power producer (IPP) solar plants and 2,600MW of wind generation from both its own Sere project and private sectors farms.

Of course, Cape Town had been using it's local hydropower station to supplement power and thereby usually managed to be a level lower than the rest of the country for load-shedding.

This is why Eskom has been able to avoid load-shedding for almost a month, despite continued cold temperatures in the country.

The Link Between Statins, Memory Loss And Dementia

Date Published: Sat, 10 Jul 2021 17:00:42 +0200

I'm not a doctor, so cannot qualify this article at all, but it is certainly interesting, and I am aware that the brain requires fat and cholesterol to work well. It is difficult to judge what triggers what side effects because often dementia or memory loss is just ascribed to 'old age' even if the patient has been taking Statins for a while.

But the World Health Organization study on trends in cardiovascular disease with relation to average cholesterol vs death rates is certainly food for thought. BUT always consult with your doctor if you're considering changes, or discontinuing any prescribed medication.

One just hopes that more and more studies will consider and evaluate any correlations found.

A new open source operating system for embedded systems: RT-Thread Smart is working to open source the world of IoT and edge computing

Date Published: Sat, 10 Jul 2021 13:11:08 +0200

There's a growing demand for embedded operating systems, and it's best when the one you build upon is open source. The RT-Thread project's R&D team has spent three years of research and intensive development to arrive at the project's latest offering: RT-Thread Smart. It is a microkernel operating system aimed primarily at midrange to high-end processors such as RISC-V with a memory management unit (MMU) and provides a competitive software platform for all industries in the embedded space.

RT-Thread Smart is a professional, high-performance, microkernel operating system for real-time applications. It offers an open source foundation for embedded devices in any market, including security (e.g., internet protocol cameras), industrial control, onboard devices, consumer electronics, and anything else using embedded technology (which is increasingly coming to mean "everything"). It's significant because, unlike traditional IoT operating systems, a microkernel operating system can fill the gap between a traditional real-time operating system (RTOS) and a comparatively large operating system like Linux to achieve the best balance between real-time performance, cost, security, startup speed, and more.

Samsung’s TV Plus is now streaming on the web for free, but has geoblocking limited to the U.S.

Date Published: Sat, 10 Jul 2021 12:52:57 +0200

So you no longer need an actual Samsung mobile device or TV but I noticed it only worked in my country with a VPN. There is some good content, but it is a throwback to the pre-streaming on demand days, with channel scheduling and TV ads.

It gives viewers in the U.S. access to around 140 streaming channels, with its lineup including channels like ABC News Live, PBS Kids, ION Plus, Vice and a number of genre-specific Vevo channels. These channels can be accessed by anyone, regardless of whether they own a Samsung device or not, but some channels do require users to sign in with a free Samsung account.

Newer study of 875 Fitbit-wearers shows Fitbits detect lasting changes after COVID-19

Date Published: Fri, 9 Jul 2021 21:11:57 +0200

One in five Americans uses a Fitbit, Apple Watch or other wearable fitness tracker. And over the past year, several studies have suggested that the devices — which can continually collect data on heart rates, body temperature, physical activity and more — could help detect early signs of COVID-19 symptoms.

Now research suggests that these wearables can also help track patients’ recovery from the disease, providing insight into its long-term effects.

In a paper published Wednesday in the journal JAMA Network Open, researchers studying Fitbit data reported that people who tested positive for COVID-19 displayed behavioral and physiological changes, including an elevated heart rate, that could last for weeks or months. These symptoms lasted longer in people with COVID than in those with other respiratory illnesses, the scientists found.

“We want to kind of do a better job of collecting long-term symptoms so we can compare the physiological changes that we’re seeing with symptoms that participants are actually experiencing,” Radin said. “So this is really a preliminary study that opens up many other studies down the road.”

Another Myth Busted: 2021 Study shows red meat not associated with heart disease, cancer or early death; but higher intake of processed meat is

Date Published: Fri, 9 Jul 2021 15:12:38 +0200

This further vindicates those lifestyle diets based on unprocessed meats, and whole foods. With meat as the common denominator, one can only assume the issue with processed meats (and other processed foods) is the additional chemical and flavour agents that get added to processed foods.

The Prospective Urban Rural Epidemiology (PURE) Study is a cohort of 134,297 individuals enrolled from 21 low-, middle-, and high-income countries.

"In a large multinational prospective study, we did not find significant associations between unprocessed red meat and poultry intake and mortality or major CVD. Conversely, a higher intake of processed meat was associated with a higher risk of mortality and major CVD."

How interoperability could end Facebook’s death grip on social media after all ActivityPub and other open standards already exist for social media

Date Published: Fri, 9 Jul 2021 12:33:28 +0200

If one factor explains the competition problem in social media, it’s network effects. The more members a social network onboards, the more valuable the platform becomes. After all, when all your friends and family are already on Facebook, you may feel the need to become a member in order to stay in the loop. And you might also end up spending far less time on other networks. This makes a tough road for all those Facebook alternatives out there.

If past judgements such as U.S. v. Microsoft are a guide, U.S. courts don’t smile on big companies that get a competitive advantage simply by being big. One way to mitigate Facebook’s network effects would be to make it less (socially) costly for people to stay on smaller, competitive networks. That’s why the concepts of portability and interoperability are so important.

Good precedents are given around phone number portability, and the fact that large social networks have had to quickly adapt their protocols before for changes such as Stories, Clubhouse, etc. What is not mentioned though is that open standards such as XMPP and ActivityPub already exist, and which successfully interconnect profiles, messages, posts, likes, media sharing between completely different social networks, and each of these social networks exists still on their own, but you can be on any one, and follow or be followed from any other network.

For those worrying about Facebook then being able to access their profiles or posts on these other networks... that possibility was always there anyway.

OpenUK's latest report: It's the foundation for established vendors even when their products are proprietary, and it is the toolbox enabling entrepreneurs and startups

Date Published: Thu, 8 Jul 2021 16:51:41 +0200

OpenUK has released the second of its three-part probe into the state of open source in Britain, finding that an overwhelming majority of businesses use the wares – but noticeably fewer are willing to contribute code back.

Figures shared in the report, which surveyed 273 randomly sampled UK companies of varying sizes and across numerous sectors, would appear to back that up. OpenUK has reported that an impressive 97 per cent of businesses surveyed use some form of open source software, with 48 per cent having increased their use in 2020 compared to the year before.

The report found a split between business sectors, particularly when it came to use of open-source operating systems such as Linux and the BSDs: While 90 per cent of technology, media, and telecommunications companies and 93 per cent of banking, insurance, and financial service sector companies reported using open-source operating systems, just 63 per cent of companies in the public sector, health, and pharmaceutical markets reported the same. Why is government lagging behind the private sector? Too much taxpayer funds?

Might be nice if a few more of those adopters turned to contributors, though
