Technique and symbols, street art tour done properly

Our guide for the epic street art tour

I have been meaning to write about this incredible street art tour I went on in Lisbon. The tour we were on was 3 hours long and many didn’t survive the full tour but me and my partner did and were so much wiser for doing so.

There was so much to say but here are some of the key parts.

The viewing angle can make all the difference

Street art from an angle

Our guide showed us different examples where something was transformed into a whole new experience when stood in the right place. The one above is well loved and exists in many photos. However our guide talked about the importance of angle and viewpoint. When we moved to the carefully marked ground point, you could see the outline of the building in front obfuscating the other half of the street art.

Unique technique

Brush strokes as unique technique

Uniqueness is obviously key in street art and our conversation with the tour guide was fascinating as he asked if I preferred technique or message. Coming from Bristol, it was about the message but he pointed out one of my likely favourite artists now (Utopia).

Utopia's fingerprint style upclose

Those things which look like brush strokes are not, they are unique ways to spray and it requires a lot of time and practice. So much so, its like a fingerprint.

Subtle statements about politics and religion

When you see the devil face you can not un-see it in street art?

Although our guide valued technique over statement. He did show us another piece I had seen previously. The first time I had seen it, it was all about the amazing tile design in Portugal but our guide, pointed out something which looks like eyes, then the mouth. Almost like a devil faces (once you see them you can’t un-see them!). I was thinking where is he going with this, then he pointed out the small church it faced and stoked up the long running issues with Catholicism in Portugal. He left with the point to me, you don’t need to make statements so explicit for them to have an effect.

Highlighting the missed

The panda likes...

Once last thing which I didn’t really see previously was other street artists highlighting other work. For example the panda can be seen across Portugal in different styles but its not about the panda. The panda likes something and is drawing attention to something important or great.

The panda likes the gay fishes

The panda likes the gay fishes which symbolises one of Lisbon’s first gay clubs and has been there for decades but is easily missed.

After this street art tour, I’m going to be a lot more choosy about which ones I pay for in the future!

Weaken encryption cyberpunk

We live in incredible times with such possibilities that is clear. Although its easily dismissed seeing the environmental impact of ChatGPT, the fascination to force people back into the office and that musk interview.

To quote Buckminster Fuller “You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.

You are seeing aspects of this with a new right to repair for up to 10 years. how solar got so cheap and John Oliver’s 2nd reaction to cryptocurrencies.


Weakening encryption is a idea which needs to die

Ian thinks: There is so much to say about the potential UK online safety bill, when it comes to encryption. In my personal experience, weaken encryption is no encryption. I’m not the only one. There is a reason why no one uses MD5 anymore.

Using photosynthesis as a source of clean energy?

Ian thinks: This energy hack is exciting to say the very least. Although very exciting its very early. I certainly encourage reading the details of the Cambridge research here.

Heating our homes using abandoned coal mines?

Ian thinks: Novel use of the many shut down coal mines, is a gem of not just an idea but something being put into practice in other countries.

The bright future of Homomorphic encryption, 

Ian thinks: This interview with Rand Hindi of zama.ai is very enlightening. The idea of Homomorphic encryption at every level is fascinating. Could it be quantum resistant? Well Rand certainly thinks so. I also expect we will be hearing a lot more about this in the next 2 years and will be a building block for the public service internet.

Bluesky finally on Android but join the waiting list

Ian thinks: Its good to finally see an Android version of Bluesky, as there is growing interest in Bluesky and the actively developed AT protocol. There is also a lot of pumped up tension from some about Mastodon vs Bluesky which is just nonsense and a waste of energy.

The danger of stochastic parrots

Ian thinks: This very shared piece calls out the real problems of the new range of “AI Chatbot.” Bender runs through history and her challenging sometimes ignorant experiences talking with those evangelising the AI future. Its well worth the read if you haven’t come across it somewhere else already.

The stochastic parrots which drives us insane

Ian thinks: Jaron’s thought on the affects of AI on our well-being is spot on. Be it consistently doubting, double checking or just the overload of AI generated content. It always makes me think an adversarial AI bot working for you makes a lot of sense.

The detailed evidence of the impact of social media on teen girls

Ian thinks: This very detailed post outlines with countless data points summarising the effect of social media on young girls. Just incase you were not clear already?

Is Kevin Kelly’s technium, unrealistic or genius?

Ian thinks: This interview was a difficult one to hear, mainly because I usually find Kevin Kelly a good thinker. However his general thoughts on tech will save us, painful to listen to and it runs through most of his thoughts. Worth a listen with a sharp critical mind.

Islington wharf glass change… at last

The difference in the new and old glass
The difference in the new (right) and old glass (left)

I had most of my windows done in my apartment this week. There is a long story involving one of my glass panels being smashed in the middle of the night (from memory of when I heard one hell of a crack)

My shattered glass window

When I woke up in the morning, I walked into the living room and shouted something pretty rude and got on the phone to our residents liaison (that is a whole different story). Didn’t get through so sent emails but the builders were already ripping out the shatter glass. I talked with them through my restricted window. Long story short, they were able to get the panel of glass to installed the next day (Thursday 6th). In actual fact they put in the panel next to it too. Nice present for my birthday weekend, but friends couldn’t believe the pictures when I showed them in the party.

I was asked if I could allow access to my whole flat for a complete glass refit on Tuesday 11th. I agreed as I was going to be away and after coming back from a spa weekend. After coming back on Tuesday evening I found the new windows except in the second bedroom. I expect that will take another 5-6 weeks.

There is a lot more to this all including moving everything away from the windows, the endless back and forth getting a date and being let down. Will it make a difference to the heat? Its hard to tell because the original designs have changed and the windows are clearly less able to open as wide. There was always plans for two open windows to provide a in and out draft but in the Living room there is one. Plus its actually smaller than the original one  and can’t open so wide.

One thing I do have is the temperature sensors in the living room and bedroom which I’m planning to map alongside the historical temperature over the last year (which I also have), to really understand the difference the new windows are making.

We live in incredible times with such possibilities that is clear. Although its easily dismissed seeing AI generated images fooling so many, OpenAI’s CEO a bit worried about the risks of AI and the cropping bug popping up everywhere.

To quote Buckminster Fuller “You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.

You are seeing aspects of this with the FTC banning better health. Content protections to identify fake/modified media and Solar tech being deployed in new and huge ways.


Mozilla takes a bite of the trustworthy AI emerging market?

Ian thinks: During the busy Mozilla Festival, was the announcement Mozilla was investing in the emerging market of trustworthy AI. We all want it but is Mozilla too early or will we look back and say it was perfect time? According to Jaron Lanier maybe Mozilla is perfectly timed.

Everything apps are all about control

Ian thinks: Twitter’s plans to be yet another everything app is painful enough, but if you look deeper into the idea of everything apps. Its super clear the reasons to be the one app to rule them all.

Whats happening in Europe?

Ian thinks: A good summary of the key concerns in Europe explained to an american audience.

The Quantum Revolution

Ian thinks: The FT’s series of podcasts about quantum is enlightening. Although quite dry its still a good listen for those like myself who know a surface level of information.

Why care about Silicon Valley Bank?

Ian thinks: I found this Rocket podcast episode, the most clear reasons why the collapse of Silicon Valley Bank actually matters. Its easy to ignore but looking at the long tail of startups and the people who rely on them, was eye opening.

Making the emerging Fediverse

Ian thinks: There is so much happening in this space of the fediverse its almost like the Metaverse has been forgotten? But I found this panel at the recent Mozilla Festival hit the tone perfectly for a workshop titled designing the future fediverse, run by myself the next day. I also recommend this indepth interview with Mastodon CEO.

Do you know what that public camera is doing?

Ian thinks:I found this Mozilla Festival session, answered one of those questions I wonder about. A QR alongside signs of surveillance, link to a human and machine readable datachain explaining its capability, who is involved, storage, etc. Best of all is the whole project is Apache 2 and CC licensed.

Sites go under but communities stay strong

Ian thinks: Timely reminder in the wake of Twitter, social sites which have gone, been archived and the rich community which stay strong.

Robots and elder care is a mess and needs work

Ian thinks: Japan for me was always the future. However this critical view of robots in elder care really brought a number of technical and cultural concerns into clear view.

Exposing a huge wearable problem

Oura wearable ring new charger checkout subtotal $59
Oura ring charger checkout

This is a bad story but I almost chuckled thinking about my wearables. The main point is about proprietary chargers for wearables and I completely agree. I always avoid proprietary chargers or ones which are not easily available elsewhere for a fair price. For example before buying the replacement to my Pebble, I bought cheap chargers for when I travel.

However back to the story, the Oura ring charger makes it all seem like a storm in a teacup, The Oura uses a USB C but has  a completely proprietary charger which is also size dependent and there are 13 sizes!

Can’t even start to explain how expensive 2nd hand chargers are on eBay. but I have a filter looking for dead Oura rings which are size 13 on eBay just incase. Even the thought of a 3rd party one is someone dashed to the wind.

You can also buy a second one, brand new from Oura at roughly 50 pounds!

Let the lyrics do the talking mix

A special anniversary mix for my partner, partly following the hearts in the clouds of Amsterdam mix. She loves vocals, while I tend to focus on the beats & rhythm. Looking through my collection of tunes, I was surprised how few had vocals.

With this, I started thinking about a mix using them and following a holiday in Lisbon. Tweaked an initial mix a few times to make it a better listen overall. The result is a mix which moves along at a higher speed of about 138bpm, matching the higher vocal trance and is a gift to my loving partner.

Of course enjoyable by all those who love vocal trance…

Enjoy it on my mixgarden or via Peertube!

Loop travel isn’t helpful to me, at all!

Settings on the pacemaker device menu

I am still loving my DJ pacemaker device but stuck on the last official firmware for my main device (I have quite a few of them just incase). I always found I couldn’t guarantee the accuracy of the looping feature if I recorded on device, so didn’t use it unless playing live. I did a blog about this a while back.

However yesterday I happened to be doing a mix and it crashed with a 201 error, loosing my currently recording mix. Very annoyed I decided to look at the lack of space left on the device (7gig left) as I don’t actually know how much working spare space it actually needs to run?

Then I started looking at the settings, I noticed loop travel which I always turned on for some reason thinking it was something good.

Deactivate/activate loop travel
This setting disallows/allows loop in-point to push end-point and vice versa.

  1. When in Mix mode, select Settings > Mix control > Loop travel >.
  2. Toggle between Off/On by swiping right

Now to be fair in the early versions of the Pacemaker firmware, the looping was hit and miss but in later versions its not needed for me.

So I turned it off did a test mix and what do you know it looped perfectly when listening back in the editor!

All this time, I avoided looping unless playing live because of this. You can imagine how happy I was going to sleep. It also means I can upgrade the firmware to the latest and get the added features.

Wait for the next lot of mixes!!!

In conversation with Cory Doctorow… in Manchester 31st May

Wednesday 31st May at 1830 - Ian Forrester In conversation with Cory Doctorow

I have the absolute pleasure of hosting the incredible Cory Doctorow in Waterstones Manchester on Wednesday 31st May at 1830.

Cory I have known for a long while through many different events and through friend. His books are simply another level, from the fictional works to the deeply powerful non-fiction ones.

There is so much to be said starting with the book of course. Now to be honest, I heard most of Cory’s books via audiobooks. However my ever so sweet partner has offered to read me red team blues, which is great because its a really good opportunity to talk about the tech/rights/data side of things which we have only touched a couple of times.

You can sign up to the conversation with myself and Cory on the waterside site. Expect a real fascinating evening of wonder and conversation covering a lot of what makes Cory … Cory.

Cory will be signing books too, so bring your questions and books.

Little update

Of course Cory has other upcoming appearances in the UK, not just Manchester

Cash still rules everything around me

Cascais in Feb

Every once in a while I’m reminded I should carry some cash.

Recently I was in Lisbon, and as usually used my card for everything. However we decided to head to the beach of Cascais, as it was going to be warm (20c in Feb isn’t bad).

Of course after a while on the beach with the Diabolo and my partner, a toilet break is needed. So going for a walk around Cascais to spot a toilet in a shop, I saw a nice restaurant called Pistachio Bar. I knew I was missing a good Portuguese coffee, so I thought I’d buy a swifty espresso and make the excuse to use the toilet at the same time.

They started to make the espresso and I went to pay for the espresso with my card. But they didn’t accept card payments under 5 euros. The manager came over and they talked about the payment, I thought about other things I could do including turning it into a Americano/long black, etc all while needing the toilet still. In the end the manager turned to me and said just take it for free.

This would be great, although I couldn’t do it, especially since I still needed the toilet. There was no way I could take the espresso and then use the toilet for free. So I looked around and noticed a full bar, and offered to buy two shots for the manager and staff member. Manager said no way because they are working, however I thought some shots for me and my partner could work nicely.

I forgot shots in Lisbon is equivalent to about 2.5 shots in the UK. After finally paying and finally going to the toilet, I walked back to the beach with a espresso and two more espresso sized take out cups filled with dark rum. But happy with the positive story and a reminder I should have some cash!


On the way back I had a similar story after getting on the train back to Lisbon and realising there was no toilets on the trains. There was time to go in the station but once again there was no option for cards, so I did that turnstile hack. A angry Portuguese woman came into the male toilets and shouted at me over and over again. I tried to explain but I was kind of busy. Afterwards I offered an explanation and showed I had a legit travel card but it wasn’t enough. Conscious I needed to get the train and my partner was waiting for me, I just had to apologise again and again as I ran to the gate for my train.

As I did, I was reminded of the Wu-Tang-Clan’s Cream. Cash rules everything around me

The night life above and under Martim Moniz mix

The night life above and under Martim Moniz

Its a return to Lisbon’s Martim Moniz after the heights of Lisbon mix, always reminds me of how the square is being used by many different people. I learned the old city wall runs right through it and its interesting to sit and watch the different people come, go and gather.

Bit of a moody mix during a lovely holiday in Lisbon but its winter so wasn’t as warm. Leaning on the tech trance side, this mix has a large number of new tunes and some bold choices with the crossfader, which I kept in. Its a mix which gets you bopping that head up and down with some excellent tunes.

Enjoy on my mixgarden or on Peertube!

See no evil: Loopholes in Google's Data Safety Labels

We live in incredible times with such possibilities that is clear. Although its easily dismissed seeing AI for everything, Elon changing the twitter algorithm to insure reach and even the BBC blue check mistake.

To quote Buckminster Fuller “You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.

You are seeing aspects of this with large scale eink screens coming, BBC R&D’s remote interaction guidelines and young people falling out of love with cars.


Mozilla Festival and so much more

Ian thinks: March is the month of the 3rd virtual Mozilla festival, tickets are available now., Mozilla is also responsible for some hard cutting research into the recent data safety labels in the Android play store, which leads to even more Tiktok privacy worries.

The Public Spaces Incubator

Ian thinks: A whole number of public service broadcaster join New_Public to reclaim public spaces with a new incubator looking to tackle so many of the ills online right now. Will it be successful, I hope so, and will be a sign of the great collaborations to come

The internet in transition

Ian thinks: Another long thoughtful piece about the state of the internet within a larger existence of time and history. A lot forgotten in the endless cycle of short term news snippets

Stop talking and buy our stuff, the endless battle

Ian thinks: A reminder of the commercialisation of the internet, services and ultimately community. This thoughtful pieces is a clear reminder of the endless battle, which has been running for so long.

Leaving tech to the private sector is a mistake

Ian thinks: Rosie gets right into the nub of the problem with outsourcing technology to the private sector. In this detailed interview with Paris, you are left with the question of what happened and why?

Its so much worst for workers caught in the a dystopia of our making

Ian thinks: Another reminder of all those people doing your wishes and for so little. The separation from that buy to the dystopia, is so deliberate and carefully done. The only thing which will make it change is our conscious buying?

Encryption burn in the potential era of the UK safety bill

Ian thinks: Signal threatens to leave the UK, Meta and most others are clear this would be a bad idea to weaken encryption to save the children. Its the endless battle but we are getting a glimpse of the real result of this bill.

The illustrated field guide to social media

Ian thinks: Zuckerman and Rajendra-Nicolucci’s illustrated guide although old is a clearly engaging and a neat way to make a point specially now.

The third room metaverse update

Ian thinks: I have been following the third room work for a while now, and was very impressed to see the FOSDEM update. If this isn’t a sign of a open, decentralised, immersive metaverse – what is?

A new meetup: Public service futures

NHS Nurse with mask and halo
Found on a wall in the Northern Quarter of Manchester

For a long while I have been thinking about the incredible role of public service in the fabric of modern society. Not only because I have worked for a public service company for almost 19 years. There is so much happening in the public space but its never really talked about or even celebrated? This is all right at a time when there is so many strikes in public services.

With all this in mind and the pandemic a lot more clear, I thought its time for a new type of  meetup. Something I have been thinking about since the end of Manchester Futurists.

Passion led us herePhoto by Ian Schneider on Unsplash

One which is focused around the future of public service, ideally hosted in public services/spaces. Spaces like public libraries, health centres, national trusts spaces, etc. Its a challenge but could be great.

Since the days of London Geekdinners, I have greatly enjoyed running meetups and bringing people together. Its hard work but with a good group of like minded people it can work nicely.

Just recently I took part as remote guest in the think & drink.

Come, Think & Drink with us

It worked well with everyone in the room but me remotely connecting via zoom. They had a camera which would rotate to who is speaking. Not a huge number of people which made it a much easier to manage event it seemed.Nice hybrid event which worked.

If you are interested in the concept or/and possibility of being involved in one in Manchester, get in touch… Equally if you know a great guest which could fit the bill talking about the future of public service in the age of the internet, get in touch.

The Dyslexic Advantage (New Edition)

The Dyslexic Advantage old and new books

A while ago, Brock & Fernette announced they were working on an update to the Dyslexic advantage. As the book had such a profound effect, I pre-ordered it and it came a couple of days ago.

Of course I’ll be seeking out the audiobook but judging by the books side by side, there is quite a lot more in the new edition. I look forward to listening to it in full again real soon.

Also a big thumbs up on the new cover!
