LibreOffice. The Best Free Alternative to Microsoft Office.

You can’t be blamed for believing you have no choice but to use Microsoft Office for your word processing, spreadsheet and other formal, work related activities.
You might even believe that any free alternative is incompatible, hard to use and simply too much trouble.
You couldn’t be more wrong.
I’ve been using LibreOffice for several years now. I’ve created and exchanged Word documents, spreadsheet template invoices, presentation software with clients and friends who have Microsoft Office for both Windows and Apple Macs – all with no problems at all.
I’ve even installed LibreOffice on clients computers and they have adapted to it and continued to work on the files they had previously created using Microsoft Office all with no problems.
LibreOffice is free, as are all the upgrades and updates but I give them a donation of several pounds every time there is an upgrade

Here is what Techradar says about LibreOffice:
“LibreOffice is so good, you’ll wonder why you ever paid for office software. It’s compatible with all Microsoft document formats, and has almost every feature you’ll find in the latest versions of Word, PowerPoint and Excel.

The suite contains six programs to cover every common office task: Writer, Calc, Impress, Draw, Math and Base. The last three are tools you won’t find in many other free office suites, and are designed for vector diagrams, mathematical functions and databases, respectively. The latter is particularly useful; free alternatives to Microsoft Access are hard to find.”

The CPU, Hard Drive and Memory

The CPU, Hard Drive and Memory

The basics of what goes into every computer

It’s understandable to be confused about the Central Processing Unit (CPU), memory, hard drive,

So here’s an explanation in terms that I hope will hep you understand what function these components perform.

The hard drive looks like a stack of three old vinyl records with a needle for each record. New ones don’t have moving parts, just microchips

I’ll start with the Hard Drive, also known as the Hard Disk; this is like your bookshelf, it stores all your application programs; your word processor, spreadsheet, photo editing or picture management software. The hard drive is also the place where the files, images, music, video are stored.  The hard drive also as a special place where your Operating System, Windows or Linux or Mac OS resides. The hard drive is commonly labelled the C drive Some hard drives are partitioned into two or more partitions; giving you a D, E, F etc drives. It’s like partitioning a room, you get more rooms but not more space.

Drives come in different capacities and spin speed, the faster the spin the better.



Memory comes in different shapes and sizes depending on what kind of computer or laptop you have. Image © Raimond Spekking

The memory of the computer is known as RAM, short for Random Access Memory. Memory is like your tabletop; the bigger it is, the more stuff from your bookshelf you can put on it.
If you have small amount of memory – and these days 2GB and even 4Gb can be a small amount of space. Older computers can’t handle more than 4Gb of memory.
There is a workaround whereby the Operating System will shuffle files between the tabletop (memory) and the bookshelf (hard drive) if the tabletop becomes crowded.
This shuffling slows your system down further and increases the wear on your bookshelf (hard drive)- especially if your bookshelf (hard drive) is pretty full.

How to explain the CPU; The CPU is commonly known as the Brains of a computer. Imagine Einstein as a juggler chef. He makes the sure the right things happen in the right order at the right time then tidies up after the job is done. (except for hard disks left fragmented my Microsoft Windows Operating System)

CPUs come in all kinds of strengths. Basically the higher the number, the more powerful and faster it is. You’ll find computers with dual core, quad core, octacore, i5, i7, processors, you get the idea.

Thousands of Swedes are inserting microchips into themselves – here’s why

Thousands of Swedes are inserting microchips into themselves – here’s why

Chips with everything.

Moa Petersén, Lund University

Thousands of people in Sweden have inserted microchips, which can function as contactless credit cards, key cards and even rail cards, into their bodies. Once the chip is underneath your skin, there is no longer any need to worry about misplacing a card or carrying a heavy wallet. But for many people, the idea of carrying a microchip in their body feels more dystopian than practical.

Some have suggested that Sweden’s strong welfare state may be the cause of this recent trend. But actually, the factors behind why roughly 3,500 Swedes have had microchips implanted in them are more complex than you might expect. This phenomenon reflects Sweden’s unique biohacking scene. If you look underneath the surface, Sweden’s love affair with all things digital goes much deeper than these microchips.

New ways to pay.

The term biohackers refers to those amateur biologists who conduct experiments in biomedicine, but do so outside of traditional institutions – such as universities, medical companies and other scientifically controlled environments. Just as computer hackers hack computers, biohackers hack anything biological.

Biohacking is also a culture and a diverse one, with many different subgroups – all with different types of interests, goals and ideologies. But within this diversity there are two main groups: “wetware hackers” and transhumanists.

Wetware hackers are citizen science hobby biologists who build laboratory equipment from household utensils. They conduct so called “frugal science”, where they find inexpensive solutions that will improve the living standards for people in developing countries. But they also do more playful experiments where plants are genetically modified to become fluorescent, or algae is used to make new types of beer.

The other group are the transhumanists, who focus on enhancing and improving the human body – with the aim, in the long run, of improving the human race. Only through bettering ourselves – and escaping biological boundaries – will humans be able to compete with AI in the future.

Often, different biohacking scenes reflect the different societies and cultures in which they develop. So, for example, European biohackers generally differ from their North American counterparts. North American groups are concerned with developing alternatives to the established healthcare practices. European groups, meanwhile, are more focused on finding ways of helping people in developing countries or engaging in artistic bio-projects.

But Swedish biohacking culture actually differs from the rest of Europe. Swedish biohackers are generally part of the transhumanist movement. And it is the transhumanists – or more specifically the subgroup “grinders” – who have been inserting NFC chips somewhere between the thumb and the index finger of thousands of Swedes. These are the same microchips that have been used for decades to track animals and packages.

What is it about Sweden?

So why are Swedes so happy to put microchips into their body? One theory put forward is that Swedes are more prone to sharing their personal details because of the way the Swedish social security system is structured.

This myth of the “naive Swede”, who innocently trusts the government and Sweden’s national institutions, is an exaggeration – which has even been noted by the Swedish Ministry of Foreign Affairs. If it is part of the explanation, it is certainly not the whole truth. More convincing is the fact that in Sweden, people have a strong faith in all things digital. Swedish people have a deep belief in the positive potential of technology.

Over the past two decades, the Swedish government has invested heavily in technology infrastructure – and it shows. The Swedish economy is now largely based on digital export, digital services and digital tech innovations. And Sweden has become one of the most successful countries in the world at creating and exporting digital products. Notable companies, such as Skype and Spotify, were founded in Sweden.

A belief in digital technology and a trust in its potential has strongly affected Swedish culture. And the transhumanist movement has built upon this. In fact, Sweden played an important part in the formation of the transhumanist ideology. The global transhumanist foundation Humanity+ was co-founded by the Swede Nick Bostrom in 1998. Since then, many Swedes have become convinced that they should be trying enhance and improve their biological bodies.

So as the world expresses shock at the number of people being microchipped in Sweden, we should use this opportunity to delve deeper into Sweden’s remarkable relationship with all thing digital. After all, this latest phenomenon is just one manifestation of an underlying faith in technology that makes Sweden quite unique.

Spooky quantum particle pairs fly like weird curveballs

Some particles that can be in two places at the same time and are not just particles but also waves, in this case, fermions, appear to move in even weirder ways than previously thought. Theoretical physicists applied extreme computing power for a week to predict the movements of fermions by including quantum optics, or light-like, ideas in their mathematical, theoretical modeling.

Physicists use terahertz flashes to uncover state of matter hidden by superconductivity

A research team has developed a new quantum switching scheme that gives them access to new and hidden states of matter. If researchers can learn to control the hidden state, further stabilize it and determine whether it’s suitable for quantum logic operations, it could allow researchers to use it for quantum computing and other practical functions.
