Rock Guitarists

This is by necessity a personal list of guitarists. I’m sure I’ve left some out, and I’ve left them out because I’m just not familiar with their work.

Banjo Players

This is by necessity a personal list of guitarists. I’m sure I’ve left some out, and I’ve left them out because I’m just not familiar with their work. Some I’ve put in because I really ought to get to know them better! But many of these are the guitarists who have touched me. Oh, by the way, the really good music stopped in 1976!

Ritchie Blackmore

We have to start with him. Of those of his era, like Jimmy Page, for me, Blackmore stands head and shoulders above them. Starting off playing pop-rock and doing sessions for Joe Meek, it all came together when Deep Purple was synthesized. Starting off with slightly psychedelic rock, and Hush which took America by storm, at Ritchie’s behest they sacked a couple of people, brought some others in and took the world by storm with Machine Head and Made in Japan. Ritchie has a reputation for being difficult (or a total asshole) and indeed in the Rainbow years, for terrible pranks and attempts to set keyboard players on fire. If he likes you, fine. If he doesn’t like you, watch out.

Tommy Bolin

One of Deep Purple’s other guitarists was, briefly, Tommy Bolin. After Blackmore left, they got together and suggested names and Tommy’s name kept cropping up. Tommy is the opposite of Blackmore: he’s a feel player, not a technician. I like him. His only album with Purple has a mixed fanbase but his solo albums are well worth checking out. I have them on vinyl.

Bernie Tormé

A guitarist who formed the backbone of Ian Gillan’s solo band, did an ill-judged but actually very good stint in Ozzy’s band, plus Atomic Rooster. I heard some of his later stuff with John McCoy which was rather good too.

Gary Moore

Here’s one I should know better. A great blues-rock player with a lovely, throaty voice.

Robin Trower

Another one I should know better. For example, I had no idea he was in Procol Harum!

Rory Gallagher

Same again. Listening to his stuff makes me wonder why it’s not part of my rotation.

Eric Clapton

He has to be on any list. To be honest, he’s like vanilla ice cream to me. He’s good, but to my mind, there are better. It did take me a while to “get” the outro to Layla though!

Jimi Hendrix

What’s there to say about him? He reinvented the style, stormed Woodstock, had a great band and came to the UK to get great management. I know at least two other guys trying to emulate his style! Deep Purple even covered one of his tracks.

Jeff Beck

Another guy I should listen to much more. He’s the master of understated playing and knows just how to hit the right note.

Honorable mentions

Jimmy Page, Dave Gilmour, Eddie Van Halen, Carlos Santana, Neal Schon, Joe Satriani, Steve Vai, Steve Morse, George Harrison, Lynyrd Skynyrd, Uli John Roth, Brian May, Michael Schenker, Peter Green and Lyndsey Buckingham from Fleetwood Mac, Scott Gorham and Brian Roberton from thin Lizzy, Paul Kossoff, Micky Moody and Bernie Marsden from Blusesnake and a few I’ve left off (which I’ve been reminded of).

In the overrated department, I’d put John Sykes. It was lovely seeing him guest with Deep Purple for Smoke on the Water, throw his guitar in the air at the climax and have it land on his head!

Photography

I used to do photography. I did some at the University of Bath, a year of nights at three different Central St. Martin campuses and I’ve taught in London and Taiwan. When I was in Camden I’d be out a few nights a week shooting people from Logan Plant to Midge Ure. Obviously, I’ve travelled around following Deep Purple, the US, Canada and much of Europe. I gave up my camera and lenses a few years ago and now rely on my phone and for zoom a Canon point and click. Well, here are a few of my better photos from the past. I *do* have a load of Cardiff, as you can see from this blog of Cardiff tourist stuff. I think my best is printed on Moo business cards but I can’t find the originals.

Fresh Ubuntu networking and host directories

Networking

When I installed ubuntu 20.04.3, I expected the ubuntu networking to Just Work. That was wrong. And apparently, there’s a new network management subsystem to worry about. A quick Google search led me to the Ubuntu docs and thence to create the file /etc/netplan/01-netcfg.yml:

network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s3:
      dhcp4: true

Then this line enabled the interface:

sudo netplan apply

Host directory

I put all my GitHub/GitLab checkouts in ~/workspace, a hangover from BBC days, along with using VMWare Fusion. Although I tend to use docker more these days. I tried mounting it from within VMWare but no luck. A pointer from a chap on Reddit led me to these lines:

mkdir /mnt/hgfs
sudo mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other

Or alternatively, add the following to /etc/fstab:

.host:/	/mnt/hgfs    fuse.vmhgfs-fuse	auto,allow_other	0	0

And there we go. Disappointingly everything I wanted didn’t work out of the box, but I got it working in the end.

Cardiff Tourist Stuff

This is an initial list of Cardiff Tourist Stuff. Assume most places here, except the really remote ones, have cafés, and even some of the remote ones have pubs close by. It’s also biased towards the West of Cardiff because that’s where I live. Look on Google maps for interesting green spaces and interesting (hopefully free) things to do.

Do check opening times, things are currently higgledy-piggledy because of the plague. If you want to do many of these, it’s worth getting Cadw or National Trust membership, depending on where you want to go.

Bear in mind you can always do a Google search and get the information I’ve left out, like the official sites for these attractions.

Main Attractions

Cardiff Castle

Cardiff Castle

If you only see one thing in Cardiff, let it be Cardiff castle. The original Norman keep is impressive in itself and it’s well worth climbing up to take in the view over the city. Cardiff uses the castle periodically to host other concerts or Welsh language events. It’s well worth a trip to see.

Cardiff Castle Apartments

Obviously, the castle got taken over by a rich mining family who took it upon themselves to build apartments. These are well worth a guided tour, through bedrooms, offices, sitting areas and at the end, the library which, like many places in Cardiff, has starred in Dr Who. There are also leftover WWII bomb shelters set in the walls that are well worth a look.

The castle and Bute park were given to the City after WWII to avoid death duties and are well worth a look. Again, events take place here from theatre to horticultural events to street food. At the top end are sports fields.

Insole Court

Owned, built and extended by another mining family, this house, this little gem in the Fairwater/Llandaff borders is well worth a visit. You can look in the house into the kitchen and various drawing rooms. You can pay to go upstairs to see a history exhibition. The gardens are lovely and they have a nice allotment at the side.

St. Fagans

St. Fagans, owned by the Earl of Plymouth after whom Plymouth Great Woods is named, is the bane of any Welsh schoolchild’s life. Set in 100 acres, it encompasses Welsh life from Iron age roundhouses to more recent prefabs with a visitor centre and museum rooms packed with Welsh history.

The house/castle itself is worth a viewing and the Italian gardens are pretty. This place is worth a day of anyone’s time. Beautiful gardens, interesting reconstructed buildings and a decent pub in the village.

Cardiff Museum

The main museum in Cardiff is well worth a look, filled with fossils and art and so much more.

Llandaff Cathedral

Llandaff Cathedral in the heart of Llandaff village heading down to the Taff is impressive. It’s been there since 500AD or so, fell into disrepair and was rebuilt into the form we see today. If you can get it on a Cadw open day get the guided tour and have your mind blown. Like much CofE it has military connections. There are cafés in the village. And pubs. One of which is very good.

It also has a Rosetti. With it comes a story.

The Bay

Senedd

The seat of Welsh democracy, important for making decisions that don’t matter when the real stuff happens in Westminster. Still, it’s how a modern parliament should look.

Norwegian Church Arts Centre

Another historic little building built for sailors back in the day when Cardiff was a throbbing port. It usually has arts and crafts displays and a café obviously.

Pierhead

Another Bute building, this was once the beating heart of the docks. Currently home to some historic exhibitions and the occasional conference.

Cardiff Bay Wetlands Reserve

A little patch of land tucked away in the docks, supposedly home to rare birds and even most recently a seal. I’ve never seen more than pigeons, ducks and swans. Oh, well.

Parks

Cefn Onn Park

To the north of Cardiff in Lisvane, straddling the M4 and reassuringly close to Ty Mawr a good pub, this is a lovely garden heading towards Caerphilly founded by Ernest Prosser, Director of the adjacent Rhymney Valley Railway.

It’s lovely when the rhododendrons are out. Also good for collecting golf balls apparently.

Llanishen Reservoir

There’s not a lot to say about this. It’s a reservoir and probably good for walking the dog. I’ve heard mutterings about building a visitor centre and having boating of some sort on it, but we’ll see.

Grangemoor Park, Cardiff

Despite this being practically on my doorstep, I’ve never been. The river Ely here used to be a lot twiddlier but there was a landfill and now it’s an IKEA and a trading estate.

FForest Farm/Radyr Hydro Scheme/Melingriffith Water Pump

Supposedly this is one of the more radioactive areas of Cardiff (there were metalworks here back in the day), this is one of my favourite places in Cardiff, on the Taff. Park your car in Radyr railway station for free, go under the railway and over the Taff then turn left and walk up to the weir.

There are birdwatching hides here and the old canal water pump.

Roath Park

Opened in 1894, it’s well worth a circumnavigation. You can even go boating on it if you’re brave. There’s a café there and some more locally if you fancy a stretch.

Caerau Fort

Set on top of a hill in unromantic Ely, bordered by the A4232 with a commanding view of the City lies an Iron Age hill fort that was in use until Roman times and beyond. Having had Time Team do geophys and had several archaeological digs, it’s recently acquired a visitor’s centre. The story of the church ruins is a sad one.

Tongwynlais

Castell Coch/Fforest Fawr Car Park

Another Bute property, this time North of the M4 and close to Taff’s Well railway station. There might be a café, but Tongwynlais has one or more pubs and maybe some cafés. Further up the hill is a car park with a nice walk and a sculpture trail.

And the sculpture trail…

Canton/Pontcanna

Chapter Arts Centre

Previously a secondary school, it became an arts centre showing films, live performances and so on. There’s a decent café with a well-stocked bar. I’ve been to various meetups there. Canton is a throbbing little village.

Thompson’s Park

An oasis at the back of Canton opened to the public in 1891 with ponds, birds and set on two levels. Nice. Take a coffee and peruse.

Penarth

Penarth Pier Pavilion

The Esplanade, Penarth – Wales, United Kingdom

Penarth is lush. It has a pier, a pavilion with a café and a theatre/cinema. The estuary front is nice for a stroll with shops and cafés.

Not Quite Cardiff

Caerphilly Castle

Another one of South Wales’ great castles, this is well worth a visit. Pay Cadw and go inside and wander around. Caerphilly has a rail station.

Cowbridge Physic Garden, The Butts, Cowbridge CF71 7BD

Cowbridge is a cute little town just a short bus hop or a drive from Cardiff. This picture is of the physic garden, but there are lots more things to see. Cowbridge has a ruined castle and a Waitrose. What more do you need?

Cosmeston Country Park

Cosmeston is a former quarry now turned into lakes and a wildlife refuge. It has a visitor centre with a café (obviously) and is good for a wander.

Dyffryn Gardens

Though dating back to the seventh century it was bought by the wealthy John Cory in 1891 whose son collaborated in making the gardens. The house itself is well worth a look. Again, easy access by bus or car, it’s halfway to Cowbridge.

National Trust – Lanlay

Out in Peterson-super-Ely, there’s very little to say about this except it’s nice to walk there and there are a couple of decent pubs in the village. There are even occasional buses.

Pysgodlyn Mawr

In the vicinity of Hensol or the A48, you can park up and take a nice walk to this fishing lake. Take a thermos and some chocolate.

Tredegar House

Situated towards Newport, this was the home of the Morgan family since the 17C. Lovely rooms, amazing gardens. This one is another National Trust property.

Nash Point

This one is definitely a drive although there might be a weekly bus. Actually hourly to either Llantwit or Bridgend. It’s nice to see the lighthouse buildings, the sheep and maybe clamber down the cliffs to the estuary.

There is potentially more to come!

Selenium: “Failed to decode response from marionette.”

“Failed to decode response from marionette.”

We were trying to move our Selenium tests into a docker container and were getting the above error response. First Google suggested increasing the memory of the container to 2G. We increased it to 3G to no effect. Deeper Googling then suggested increasing shared memory. Initially, it was 64m. We raised it to 256m and it magically worked! Our script for creating the container:

docker build . -f docker/Dockerfile --label cdx_selenium -t cdx_selenium
docker run --shm-size=256m -m3000m --cpus=4 --privileged -d  --name  cdx_selenium cdx_selenium 
docker exec cdx_selenium bash -c 'systemctl daemon-reload && systemctl enable xvfb.service && systemctl start xvfb.service'

We also needed to install dbus-x11. In theory we shouldn’t need to do the systemctl outside the Dockerfile.

MacOS Big Sur 11.5 update failed.

This repeated MacOS upgrade fail annoyed me. I saw stuff on the internet about Apple’s servers being overwhelmed. That wasn’t it. It turns out I only had 4G of free disk space left.

I’m never getting only 128G of SSD again. Deleting 8G of Spotify cache, and it worked smoothly, if slowly.

Simples!

2021 – Climate change and Welsh independence.

Cefn Onn

2021 has been an odd year.

Despite the supermarkets staying open during the lockdown, we’ve been getting far more food delivered; not just supermarket food but heat-at-home restaurant meals and fruit and veg from Wellocks, suppliers to Michelin-starred restaurants.

That said, two things have been standout in the last 12 months: climate change and Welsh independence.

Climate change podcasts

I don’t know whether it’s that I’ve been listening to many more podcasts and been adding scientists to my Twitter feed (thanks @robinince), such as Helen Czerski, Brian Cox, Alice Roberts, Katie Mack, Mya Rose Craig, Hugh Warwick and podcasts from the likes of 5×15, The Science and Media Museum and many more. It seems to me that scientists and amateurs are getting much noisier about climate change. Of course, it’s turned out that Greta Thunberg was right all along. Also maybe it’s just awareness but there seems to be so MANY more podcasts too.

Living in a country that contributed hugely to the increase of CO2 into the atmosphere helps concentrate the mind. Because of the lockdown, we’ve been taking that car out only once or twice a week and I see an electric car in our future. As it is, we live in a wood-clad “green” flat and are surrounded by trees in a borderline countryside area. Wales is 3rd in the world for recycling. I’m not sure what more we could do for the environment.

Welsh Independence

On the subject of Wales, in the last year, the subject of Welsh independence has started to gain traction. The non-political group yes.cymru have gone from nothing to nearly 20,000 paying members and 50,000 Twitter followers. Welsh Labour and Plaid Cymru supporters are behind the idea too. The electorate polls at 25%-40% in favour.

As I’ve said before, Wales has a GDP per head which puts it on a par with Spain. We’re shy between £5-£10 billion pounds a year but hey, with European support we can claw our way back as Ireland did. I’ve blogged about Wales’ potential before. Also, accounting properly for water, electricity and HS2 would help by a few billion in our favour. Oh, and we pay a disproportionate amount for defence, another £1.9 billion. It doesn’t help their case that we appear to have a bunch of incompetents in Westminster.

So there you have it. These are two things that are now occupying much more news space, internet space and headspace.

MySQL 8.0 oddity – passwords and password policy

These are all things you can find elsewhere but a couple of password issues came as a surprise to me

MySQL
These are all things you can find elsewhere but a couple of password issues came as a surprise to me when a legacy system got the MySQL 5.7 upgraded to 8.0.

Firstly, password policies are much tighter. There’s a plugin that by default demands an uppercase letter, a number and a punctuation character. That foxes our legacy system whose installer just generates lowercase letters and numbers. Uninstall it.

UNINSTALL COMPONENT 'file://component_validate_password';

Another good one was the the library I was using, and didn’t want to upgrade, didn’t know the default authentication to connect to MySQL. That was easily fixed:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'xxxxxx';
Query OK, 0 rows affected (0.03 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

Having gone from a Centos 7 MySQL accidentally to MySQL 8.0 and back again, that’s a world of pain involving the recompiling of the Perl DBD::MySQL and finding the correct .so library.

Green Wales

Being green is all the natural resource we’ve got left in Wales pretty much.

Insole Court

Being green is all the natural resource we’ve got left in Wales pretty much since the rich folks and the English took our coal, tin, copper and so on.

This blog is also going to come from an Indy viewpoint. Welsh independence has gone from nothing to 40% in the last few years. Independence is worth bearing in mind whichever side you fall on. I’ve fallen foul of people who think the world revolves around Westminster on Reddit. We got annexed in 1284 and made a union in 1536, not on the same basis as Scotland.

Independence polling

40%. It’s only time.

A poll suggesting that backing for independence among Welsh citizens is at a record high should serve as a warning for the UK government and prompt it to work harder at its relationship with the devolved nations, supporters of the union have said.

https://www.theguardian.com/uk-news/2021/mar/04/westminster-warned-as-poll-shows-record-backing-for-welsh-independence

GDP

We have a higher GDP per capita (£23,866 in 2018) than Spain (£22,000) and Solvenia (£20,000) and many other European countries.

GDP per head in Wales in 2018 was £23,866, an increase of 2.9% on 2017. This compares to Italy’s GDP/capita of £25,000, Spain £22,000, Slovenia £20,000 and New Zealand £30,000.

https://en.wikipedia.org/wiki/Economy_of_Wales

In the 1950s Wales’ GDP was twice as big as Ireland’s; by the 2020s the economy of the Irish Republic was four times the size of Wales’. Thanks EU.

Energy

Wind turbines

We export water and electricity to England. We are not short of water here. I even have a twitter feed of our local river to tell me how deep it is. Yes, it floods.

By one calculation Wales’ present export of water to England, from the Elan Valley to Birmingham and from Lake Vyrnwy and Tryweryn to Liverpool, could be worth as much as £4.5 billion a year.

https://www.iwa.wales/agenda/2012/04/when-white-water-could-become-white-gold/

Wales is a net exporter of the electricity it generates.

Wales energy

https://www.bbc.co.uk/news/uk-wales-29799716

We could do better at both of these.

Put energy creating lagoons around the harbours. This has come and gone but apparently is back again.

“Providing low-carbon, predictable renewable energy, tidal lagoons will deliver reliable and flexible electricity whatever the wind conditions or time of day – ensuring grid security and stability. Moreover, tidal lagoons have an exceptional operating life, at over 120 years, over three times a wind farm and twice a nuclear plant, and significant co-benefits that other schemes do not bring, such as protecting communities and businesses from rising sea levels.

https://www.offshore-energy.biz/industry-welcomes-welsh-governments-tidal-lagoon-challenge/

We could do more wind and solar energy too.

Forestry

North/South forest? Go for it. The “national forest”. We have expanses of temperate rainforest.

https://gov.wales/national-forest-wales-woodland-sites

Rewilding

Reintroduce lynx and bears into that forest? Yep. We recently got beavers back:.

Naturalist and television presenter Iolo Williams welcomed the pair to the reserve near Machynlleth and said it was a “big day”.

“They [beavers] used to be here, they should be here and I would like to see them back on Welsh rivers,” he added.

“They can help tackle important issues like flooding, creation of new habitats – they’re an important part of that as environmental engineers.”

https://www.bbc.co.uk/news/uk-wales-56565050

Eurasian lynx

Five landowners in Wales have shown interest in hosting the reintroduction of lynx, a conservation group has said.

In 2015, the Lynx UK Trust put out a plea for anyone who would be willing to allow their land to be used.

Its chief scientific advisor, Dr Paul O’Donoghue, said five sites in mid Wales came forward and it would consider their merits in future.

https://www.bbc.co.uk/news/uk-wales-41024161

Wolves would be nice. Bears are sadly an April fool:

https://nation.cymru/news/bears-return-to-deserted-welsh-village-during-lockdown

Getting eels back would be good. We’re 70% down.

But the rapid disappearance of eels from the nation’s waterways – dropping by an alarming 70% in a generation – is now a major cause for concern among naturalists.

https://www.walesonline.co.uk/news/wales-news/wales-declining-eel-population-1884407

Replace pines with deciduous trees? Yes.

https://naturalresources.wales/media/681031/gpg7_forest-resilience-2_species-diversity.pdf

Bogs

Restore the bogs? This is happening.

Healthy peatland and raised bogs in good condition absorb carbon from the atmosphere which means they are important in the fight against climate change. If raised bogs are not in good condition they release harmful carbon into the atmosphere.

https://naturalresources.wales/about-us/our-projects/nature-projects/new-life-for-welsh-raised-bogs/

Public transport

Treble public transport in Cardiff? No brainier. Fuck all has happened with this in the seven years I’ve been in Cardiff. Allegedly some things are happening. In all that time there’s been a “Metro Plan”. Maybe we’ll move on from horse-drawn open-topped trains.

The South Wales Metro is an integrated public transport network that will make it easier for people to travel across the Cardiff Capital Region, transforming rail and bus services as well as cycling and walking. 

https://tfwrail.wales/metro/south-wales/

Energy efficient houses

Build energy efficient houses. I’m lucky enough to live in a B rated place. All places should be this efficient.

Seafood

Our seafood is amazing. Shame Westminster fucked that up.

Seafood

Sheep

There’s 3x as many as there are people. We should probably have more, within their environmental impact.

Sheep

Dead zone

Restore the Cambrian mountains. There’s a 300km2 dead zone.

In the southern Cambrian Mountains, in central Wales, there’s a Terrestrial Dead Zone of around 300 km². It’s composed of degraded blanket mires, entirely dominated by a coarse grass called Molinia, in which other lifeforms, such as birds and insects, are scarcely to be found.

https://threadreaderapp.com/thread/1365217257111

Cardiff

Cardiff is nice and green, there’s plenty of woods, open fields and so on to just go hang in. Sadly a few green spaces are under threat. That’s not surprising in a growing city. The rivers could do with cleaning up. We used to have eels and way more fish. I’ll blog about this at another time. I’ve exported all my saved pins from Google maps.

Summary

There’s so much potential but nothing will happen while we’re under Westminster’s thumb. In EU terms, we are by no means the smallest country in Europe and our GDP is OK. I’d like to see more action. In the last year of lockdown green issues have come more to the forefront. I want a green future for Wales.
