All things Google (and more) – 13th February 2020

Boot-up

Visit to Barclays Eagle Labs – now arranged for the next meeting – 27th February. Here’s some more detail about what they’re all about.

As part of Barclay’s community commitment,  we have also opened a new office in Cardiff designed to help businesses grow and start up in Cardiff. Great for budding Entrepreneurs (which statistics show can be high in the over 50s)  and inventors. Part of the Eagle Lab office hosts  a “Maker Space’ that houses laser cutting, vinyl printing, 3D printing, electronics equipment including soldering etc. It has a distinctly digital feel too with a really switched on Engineer running the lab. I will contact them to discuss what is actually available there and suggest things you might be interested in.

I have  13 confirmed attendees. I’ll contact Ashley Croome (the switched on Engineer) with details of who’s coming and discuss whether we need to split into two groups, or just stay at one. After the Science Group visit he advised me … “For group sizes, with the science group we had about 10-15 per group and that seemed to work really well as it wasn’t so overcrowded that people didn’t get a chance to ask questions, and try things like the VR we have set up here.”
The venue for the visit is:
Barclays Eagle Lab, 1st Floor Brunel House, 2 Fitzalan Road, Cardiff, CF24 0EB

Next meeting after Eagle Labs is on 12th March, then Paul will lead on 26th March and 23 April. I’m assuming there will not be a meeting on 9th April because of Easter. I’ll be back after that … for a while at least 🙂

Whats Up with WhatsApp – an interesting discussion about how you can “trick” an Android tablet into believing it’s a phone (without a SIM) between Margaret, Jim, Paul and myself. I’m not sure I’m completely the wiser, but it revolves around a solution for an Android tablet that Paul had already described (which works for him) and is also described in this post and on an iPad this post describes how to do it. If you want to see the WhatsApp log of the chatter and confusion, look here.
Undo Send function in Gmail (from desktop, not mobile) setup in Gmail Settings > General, selectable from 0 -30 secs, so not as long as I thought.
Clearing Off-Facebook Activity and a video to help you.
The death of Adobe Flash – Apple puts the boot in.
We had a question about Exporting email from Tiscali (TalkTalk) from Ann, who was concerned she might lose her old emails. It looks like the most useful way of doing it is to setup POP3 Forwarding of an Email account into Gmail – in Gmail > Settings (gear wheel) in the browser …

… get the correct settings for your server, as in …

and as long as you’ve selected Enable POP for all mail (even mail that’s been downloaded) and as long as your email provider supports POP3, your email should be downloaded from that server and into Gmail.

Gear Guide

Has anyone bought, or obtained anything recently they’d like to tell us about? It doesn’t have to be a computer, laptop, tablet or phone – just something that’s digital, ie used a computer processor in some way?
Here’s a provocative thought … what applications do you use that depend largely upon the use of a peripheral? Are you using the best application for that hardware? Perhaps you don’t have any choice, but if you do perhaps you should choose the most appropriate application for the hardware.
Jim updated us on his broadband upgrade using his new Router liked to a SIM-card (have I got that right, Jim?). He’s also purchased a dongle to watch live Freeview TV. This is not connected to the broadband, but it might cause his battery to lose power a bit more rapidly than it did before.

Apps Galore

That slot in the meeting where members are encouraged to share their experience (and possibly excitement) at a new app they’ve started using for their smartphone, tablet, laptop or desktop machine.
OpenStreetMap – creating maps for collaborators – a couple of examples – Canals and Railways, Land use and Buildings, but what about creating a shared Google Map ?

What’s IT all about?

That occasional slot in the meeting when we might do a bit of explanation of terms used in Computing, or in the use of digital devices.
Mesh Networks – which ones are members using:
Paul – BT solution
Don – Deco M4, with TP-Link AC1200
WiFi Reception – interesting fact … the range of the WiFi Router decreases as the signal frequency increases. However, the inverse also holds true, namely the closer you are to your WiFi router the greater the bandwidth you have as signal frequency increases. Therefore in a big house, maybe you need to employ 2.4Ghz; in a compact house it’s a good choice to use 5Ghz and maybe even employ a router that supports tri-band – which might give the best of both worlds!

The main topic

I use Google apps on my desktop and mobile devices – and I’m an Apple fanboy! However, it’s just come to my notice that a couple of Google developments have passed me by, which have caused me to think about whether I might be better to use more Google apps on my Apple mobile devices, rather than the native Apple apps
I rely on Gmail and Calendar. I have done for years. It’s a family joke – “if it’s not in the Google Calendar – it’s not happening”. I have been caught out  few times. I also use (and will continue to use) Google Maps extensively for mapping, the Apple version is not quite there yet, but it’s improving!
I have used Google Hangouts and Paul and I have tried to get that working – but it’s impractical to even try and demonstrate it at this location 🙁
We have looked at Google Assistant, as a way of interfacing with the virtual world, but I haven’t embraced it – probably because I still rely on the native Apple mobile apps and Siri is the way into these; but, it would have to be said, probably not as well as Google (or Amazon – Alexa).
But now I’ve become aware of Tasks, which you can access from Gmail, and  Calendar and if only it interfaced completely with Google Assistant – I think I’d be making the switch to using more Google apps on my Apple devices, but, and there’s always a but … why does Google makes things so difficult! Just remember there’s Google Keep (for notes) and Google Reminders (for reminders); and … you always have to remember Google have the nasty habit of dropping things just after you’ve got used to using them – Reader, Picasa and Google+ to name but three! Let’s have a look!
 

 

Systems that operate – 9th January 2020

Boot-up

Happy New Year

Your Computing or Digital Resolutions? These were received and will prove very useful in framing the programme for the next few months. I’ll try and get a pretty copy of it prepared and provide a link to it so that you can all see what you wanted to achieve!

News and other issues raised

Last time I showed you Ookla’s Speedtest to find out the bandwidth (speed) of your home internet connections from wired and WiFi connections to your Router. We’ve got some Speedtest results posted on WhatsApp, but could do with some more. Any comments from David, Jim, Marilyn and Paul?
Anyone on Virgin, who’s seen an improvement in their bandwidth? They’re upgrading all their customers (pre 1st Dec 2019) to 100Mbps download.
End of life for Windows 7  (with video)
What does this mean? What should you do? Further reading with suggested alternatives should you not wish to upgrade to Windows 10.

Did anyone buy (or was given) anything interesting for Christmas

What about the Turing Tumble – Build Marble-Powered Computers
I bought an Apple HomePod and we’re delighted with it, although Siri does seem to be selective in what it finds from our Music Library, preferring to search Apple Music rather than look for our locally installed tracks. I’ve linked it to our Sonos Play:5 system – which has very good sound quality and through our Apple TV I can also play the Siri selected music through the HiFi system. It’s been an interesting project!

That slot in the meeting where members are encouraged to share their experience (and possibly excitement) at a new app they’ve started using for their smartphone, tablet, laptop or desktop machine.
Mario told us about an App that he’s found very useful in getting vertical lines for door frames, etc – or even getting the coffee table level! It is called Clinometer HD (on Android) and I think the same app is called Clinometer + bubble level (on iOS) where it costs £1.99.
Renee told us about iNaturalist which is Free on iOS (not sure whether it’s available on Android) which is helpful in identifying matters natural (plants, etc.)
I added there was an app called iGeology which gives you an idea of the geology of anywhere in the UK through maps.

What’s IT all about?

What’s an Operating System?

I thought given the immediacy of the Windows 7 “end-of-life” date, that discussing and talking about Operating Systems might be appropriate, and thanks Paul for planting the seed of the idea!
First a set of videos to set the scene …
An introduction (see Reference List below for text accompanying this video) …

… and the place of Operating Systems in a historical context …

… and then the beginnings of a technical information fo what they do …

[If you want to learn more you can follow the later videos in the series of the last one.]
So … some of important functions of an Operating System that originated and still exist in multi-user computers  – the ones we may connect to when doing online banking, or shopping, are:

  • Memory Management
  • Processor Management
  • Device Management
  • File Management
  • Security
  • Control over system performance
  • Job accounting
  • Error detecting aids
  • Coordination between other software (applications) and users including the provision of application program interfaces to allow applications access to core OS functions

… and some of the important activities that an Operating System performs on a shared multi-user mainframe-like computer are:

  • Security − By means of password and similar other techniques, it prevents unauthorised access to programs and data.
  • Control over system performance − Recording delays between request for a service and response from the system.
  • Job accounting − Keeping track of time and resources used by various jobs and users.
  • Error detecting aids − Production of dumps, traces, error messages, and other debugging and error detecting aids.
  • Coordination between other softwares and users − Coordination and assignment of compilers, interpreters, assemblers and other software to the various users of the computer systems.

Of course Operating Systems have evolved from being programs that manage multi-user access to a shared computer, to being the program that controls (manages) a single-user’s access to their personal computer or mobile device through a User Interface – perhaps the feature most users equate with an Operating System –  but that’s not where it ends.
The OS is critically involved in the way that computers are connected to networks, and in the way that computers (devices) are connected to each other. This extension of the Operating System (the incorporation of the way personal computing devices connect together using a LAN, dial-up or WiFi into the code of the OS) is where we are today. Together they work effectively as the brain of the computer.
From the second reference below …
An operating system is the core set of software on a device that keeps everything together. Operating systems communicate with the device’s hardware. They handle everything from your keyboard and mice to the Wi-Fi radio, storage devices, and display. In other words, an operating system handles input and output devices. Operating systems use device drivers written by hardware creators to communicate with their devices.
Operating systems also include a lot of software—things like common system services, libraries, and application programming interfaces (APIs) that developers can use to write programs that run on the operating system.
The operating system sits in between the applications you run and the hardware, using the hardware drivers as the interface between the two. For example, when an application wants to print something, it hands that task off to the operating system. The operating system sends the instructions to the printer, using the printer’s drivers to send the correct signals. The application that’s printing doesn’t have to care about what printer you have or understand how it works. The OS handles the details.

The OS also handles multi-tasking, allocating hardware resources among multiple running programs. The operating system controls which processes run, and it allocates them between different CPUs if you have a computer with multiple CPUs or cores, letting multiple processes run in parallel. It also manages the system’s internal memory, allocating memory between running applications.
The operating system is the one big piece of software running the show, and it’s in charge of everything else. For example, the operating system also controls the files and other resources these programs can access.
Most software applications are written for operating systems, which lets the operating system do a lot of the heavy lifting. For example, when you run Minecraft, you run it on an operating system. Minecraft doesn’t have to know exactly how each different hardware component works. Minecraft uses a variety of operating system functions, and the operating system translates those into low-level hardware instructions. This saves the developers of Minecraft—and every other program that runs on an operating system—a lot of trouble.
In complex control systems such as a power station, or weapons system there will be elements of a stripped down operating system at the core of the dedicated task the system is programmed to carry out. It is important that there is at the heart of every system some core code that interacts with the basic components of the system – its processor, its memory, the resources it calls upon and the devices it controls. That is the Operating System.

… and for a bit of fun, back to 1998 when personal computers first became a piece of equipment that you’d consider having in your living room …

… by the way, I have a friend who still has a working G3 iMac. I’m moving his work on it on to a new iMac in the next couple of weeks.
