Free online courses to boost studies during Covid-19 lockdown

The Covid-19 pandemic and lockdown measures put in place in most countries provide a great opportunity to online studies. Below is a list of online course providers, many of them are offering learning content for free during Covid-19. Normally, verified certificates (after you complete a course) require a fee but some teaching materials are free. I rank them based on number of free courses they offer, the range of subject areas, and their reputation.

1. edX (US) is the best free online course provider and the second largest MOOC provider in the world. It doesn’t have as many courses available as Coursera, but all edX courses can be audited for free because edX is a non-profit organisation. It focuses on natural sciences and humanities. Popular subject areas are languages and computer science.

2. Coursera (US) is the largest MOOC provider in the world. Coursera offers over 1,000 free courses across 11 subject areas on beginner, intermediate, mixed and advanced levels. The reason I rank it as no. 2 is because the majority of Coursera content is not free.

3. FutureLearn (UK) is a UK-based organisation. Most of its university partners are in the UK and Europe, but it also has a few university partners in US, Australia and S Korea. There is a wealth of free short online courses at FutureLearn. Subject areas include creative arts and media, healthcare and medicine, teaching, science and engineering, and maths.

4. Udemy: offers a huge number of free online courses. Udemy encourages users to search for courses with a prominent search box, and the platform feels less formal than others. Courses are run by experts rather than through direct association with universities.

5. Udacity (US): provides nanodegrees focus on certain innovative topics such as AI, self-driving cars. Although Udacity has stopped releasing free courses, it still has some courses in its catalog that are free to audit.

6. Linkedin Learning (previously known as lynda.com): doesn’t offer the same amount of degrees and certifications provided by edX and Coursera. Linkedin Learning is used by many employers for employee training and CPD. There are limited numbers of free courses on Linkedin Learning. However, you can access Linkedin Learning paid courses for free by registering for Linkedin Learning free trial, which will give you 1-month free access to all premium courses, and you can take this 1-month free trial again after 12 months.

7. Pluralsight: provides 7,000+ free tech courses during Covid-19, including programming, machine learning, and cybersecurity. A subscription normally costs $29 per month, now only requires simple sign-up.

8. iTunesU: is a convenient place for free online education on any app-ready Apple mobile device. On iPad, iPhone, or iPod touch, users download the iTunesU app. The tool offers online courses with full lectures. However, courses are often a mix of free podcasts, videos, and paid content.

9. TED-Ed: is a site chocked full of educational videos. Most include impressive animation, and all are ten minutes long or less. Not only is TED-Ed an excellent site for the curious, it also includes supplemental materials and quizzes on the videos. This makes the site extremely useful in formal education settings and entertaining ways.

coat-of-arms

Heraldry probably began with the knights in armour. When wearing a helmet in battle or in tournaments a knight could not be recognised; so he used symbols to decorate his shield and surcoat. The surcoat was the loose garment worn over the armour to protect it from rain or hot sun and actually was the "coat-of-arms"; it was decorated on the front and back with the same device as on the shield. The correct expression for entire design is an achievement . An achievement consists of the shield, helmet, rest, wreath, mantling and motto. These are the main parts. To them can be added supporters and a compartment. In the centre is the most important part, the shield . The surface of the shield is called the field  and on it the colourful charges are placed. The shield is called the arms or coat-of-arms  and can be drawn in any shape - in an upright position or slanting, which is the position it would fall into if hung on a peg. In Heraldry it slants to dexter. The helmet denot

You can find your Wireless Network Key on Virgin Media Wireless Router

We have a new netbook computer, and don't know where to find network key, which is needed to setup wireless connection. A network key may also be called WEP (Wired Equivalent Privacy) key or WPA (Wi-Fi Protected Access) key. A wireless network key is a security feature that prevents unauthorized users from accessing a wireless network. An unprotected network is an unlocked virtual door, anybody within range can piggyback on the network undetected. I use Virgin media broadband with a Virgin media wireless router, this router has a WPA key taped on the router, that WPA key is an English word consisting of 10 letters. To tape network key on the router is a good idea, because we may never lose or forget a wireless network key as long as we possess the router.

The Meaning of Derby City Council Logo

Derby City Logo The logo of Derby City Council looks quite abstract and modern. I wonder what's the meaning of it? The lower-left part of the logo looks like a snail (or the initial letter D in Derby?), the upper-right part seems a river, (Derwent river?) these two parts are connected by a straight line at the bottom. I did some searches on the web trying to find out the true meaning of Derby City Council logo, but without success. So, I wrote to tourist information, and got the answer from Michael: The Logo is a representation of two of Derby's oldest emblems, one being a ram the other a buck (deer). Obviously the logo is a modern interpretation of these two figures so it is not obvious unless you know what to look for. Most people do seem to agree with you that it looks like a snail however. Ram! the curly horn of ram looks like a snail indeed. The ram and the deer are from coat of arms of City of Derby, In this coats of arms, we can see the deers both in shield (arm
