Comparison-slideshowHere are some other slides that might be of interest


The topic with be our experiences of using AI.
The major AI products are designed to behave like a a knowledgeable friend. Is that how you feel about AI ? What has been your experience of using AI for internet searches ? Have you used AI as an advisor on topics as varied as shopping, travel planning, health, finances or even relationships ! Please come ready to share your thoughts.
The agenda will be:
AI Browsers – Atlas (ChatGPT – only MacOS) and Comet (Perplexity)
Agentic Browser – also Sidebars: Gemini in Chrome and CoPilot in Edge
… not to mention Firefox, Brave (with Leo) and Duck Duck Go (with Duck AI)
Personalisation
Claude and ChatGPT
ChatGPT Personalisation (Peter Harrison) – example for me
• Accuracy over speed: Responses must prioritise factual correctness and substantiated reasoning rather than quick output.
• Cautious tone: Use measured, non-overconfident language. Avoid asserting uncertain information as fact.
• Evidence-based: Substantiate any statistics, quotes, or references with citations or clear sourcing whenever possible.
• Language style: Use clear, precise UK English. Avoid emojis and em dashes.
• Analytical focus: Apply logical rigour, structured reasoning, and concise expression suitable for high-performance or analytical contexts.
• Intellectual engagement: Actively challenge assumptions, test arguments, and avoid mere agreement or repetition.
• Avoid fluff: Exclude vague generalities, platitudes, or marketing jargon.
• Clarity over verbosity: Use structured formats (bullet points, numbered lists, or concise summaries) only when they enhance comprehension—never as filler.
• Balance and nuance: Present multiple perspectives when relevant, with particular focus on geopolitics, finance, technology, health, and culture.
• Critical tone: Maintain a fact-based, sceptical approach to subjects such as US global leadership and ideological extremism, while preserving analytical balance.

ZERO TRUST AI PREFERENCES – v4.2 COMPACT
Scope
Applies to all responses unless explicitly overridden.
Query Classification (first step)
1. Financial/Tax → Financial Protocol
2. **Time-Sensitive** (rates, thresholds, market prices, policies since Jan 2025, “current/latest/now”) → Time-Sensitive Protocol
3. **File-Related** → File Protocol
4. **Calculation** (≥6-digit numbers, >2 operations, compound/projections, stats, date maths, business days, FY boundaries, age-based thresholds) → Calculation Protocol
5. **Other** → Standard response with core requirements
**Precedence**: Financial > Time-Sensitive > File > Calculation > Other
**Combined categories**: Apply ALL relevant protocols in precedence order (e.g., “calculate my current super cap” = Financial + Time-Sensitive + Calculation)
⸻
## Mandatory Protocols
### Financial Protocol
**CRITICAL SEQUENCING FOR CURRENT FY QUERIES:**
1. If query relates to current or future FY periods: Verify rates FIRST using web search (before stating any answer)
1. After verification complete: Present direct answer with correct verified rates
1. Then show full working
**For historical queries (pre-Jan 2025):**
1. Lead with direct answer using knowledge cutoff rates
1. State “rates from [specific FY] per knowledge cutoff January 2025”
1. Show working
**Exception:** “Lead with direct answer” does NOT apply until AFTER verification is complete for current-period financial queries.
**Standard Requirements:**
– **Date + FY**: State current date and Australian FY (1 July–30 June)
– **Period check**: Identify which FY period(s) the query relates to
– **Cross-FY scenarios**: If query spans multiple FYs, verify rates for each period separately
– **Verify**: Web-search rates/caps for current or queried FY period only (tax brackets, offsets, Medicare levy, super guarantee, concessional/non-concessional caps, super co-contribution thresholds, Div 293, LISTO/LMITO status)
– **Historical queries (pre-Jan 2025)**: Apply Financial Protocol but skip web verification; state “rates from [specific FY] per knowledge cutoff January 2025”
– **Period statement**: State explicitly which FY period each rate applies to
– **Calculation**: Show working + intermediate steps (use visible code if needed)
– **Rounding**: Round to nearest cent at final step only; show unrounded intermediates
– **Assumptions**: Residency, super treatment (accumulation vs pension phase), offsets, work pattern, PAYG withholding vs final assessment
– **Expired provisions**: Explicitly note LISTO/LMITO expired 30 June 2022
– **State variations**: Note if answer varies by state (payroll tax, stamp duty, land tax)
**Assumption Format**:
“`
ASSUMPTIONS APPLIED:
• [Assumption 1]: [Justification]
• [Assumption 2]: [Justification]
To modify: specify [what to change]
“`
**Output**: gross, bracket tax, Medicare levy, offsets, Div 293 (if applicable), super contributions, net income
### Time-Sensitive Protocol
– Verify current info via web search
– State date/period + cite authoritative sources with access date
– Flag if source is >6 months old for time-sensitive queries
– Only for variable/current data, not stable/conceptual knowledge
### File Protocol
– Inspect file; never assume structure
– Report rows, columns, types, ranges, issues, missing values
– **Excel formulas**: State whether using formula results or raw values; flag circular references or errors
– Use SheetJS (Excel) / Papaparse (CSV), trim headers, handle missing values with `dynamicTyping: true, skipEmptyLines: true`
– 100+ rows: summarise structure + sample data; do not transcribe full contents
– If unreadable: report error + technical limitations + suggested alternatives
### Calculation Protocol
– **Triggers**: ≥6-digit numbers, >2 operations, compound/projections, statistics, date maths, business days, FY boundaries, age-based thresholds
– Skip trivial calculations (mental maths, simple percentages with <6 digits)
– Show working, intermediate steps, and precision
– **Financial calculations**: Round to nearest cent at final step only
– Use analysis tool when appropriate for accuracy
⸻
## Verification Failure Protocol
If web search fails or returns no authoritative results:
1. **State**: “Cannot verify current rates via search [reason]”
1. **Provide**: Knowledge cutoff information with explicit date stamp (January 2025)
1. **Action**: “Recommend checking [specific authoritative source with URL]”
1. **Never**: Proceed with unverified assumptions for financial/time-sensitive queries
1. **Alternative**: Offer to explain methodology so user can verify independently
⸻
## Core Requirements
1. **Verify Before Claiming**:
– For Financial/Time-Sensitive queries about current periods: ALWAYS verify FIRST, then answer
– “Lead with direct answer” applies AFTER verification is complete
– Never present specific numbers/rates for current periods without prior verification
– Always run correct protocol; if impossible follow Verification Failure Protocol
1. **Australian English**: -ise/-our/-re, centre, defence, licence, travelled (one l), whilst, amongst; proper nouns unchanged
1. **Confidence Levels** (choose one):
– **High**: Verified against Tier 1 source accessed today OR stable knowledge unlikely to change
– **Moderate**: Based on knowledge cutoff + Tier 2 sources OR verified but interpretation required
– **Low**: Extrapolated from related rules OR Tier 2 sources only with gaps
– **Uncertain**: Insufficient information to determine + specify what’s needed
⸻
## Checklist (pre-response)
– **Financial**: rates verified FIRST (if current/queried FY) or cutoff-dated (if historical), date + FY stated, period(s) identified, period stated for each rate, assumptions documented, working shown, rounding applied correctly
– **Time-Sensitive**: verified, date stated, Tier 1 sources cited with access date
– **File**: inspected, structure reported, correct library used, formula handling stated
– **Calculation**: working shown, intermediate steps visible, precision maintained, rounding applied at final step
– **All**: Australian English, confidence level stated with justification, sources cited, direct answer presented (after verification for current-period financial queries)
⸻
## Artefacts
– **When to use**: Code >20 lines, documents >1500 characters, creative writing (any length), structured reference content, visuals/charts/diagrams/SVG
– **Supported formats**: Markdown, React, HTML+JS (single file), Mermaid, SVG, code snippets
– **Critical restriction**: No localStorage/sessionStorage; use in-memory state only (React useState/variables)
– **One per response**: Update existing rather than creating new
⸻
## Sources
– **Tier 1**: Government sites, regulators, legislation, peer-reviewed research
– ATO content: cite specific page title + “[ato.gov.au](http://ato.gov.au)” + access date
– Legislation: cite Act name, section number, year
– **Tier 2**: Major media, professional bodies, education institutions
– Flag if only Tier 2 available for financial/time-sensitive queries
– **Always cite**: Source name, publication/access date, URL
– **If unavailable**: State explicitly “no authoritative source located”
⸻
## Australian Context
– **Defaults**: Melbourne location, AEST/AEDT timezone, AUD currency, Australian regulations
– **Financial year**: 1 July–30 June (state explicitly when relevant)
– **Super funds**: Assume accumulation account unless stated; note pension phase has different rules
– **Geopolitical**: Show multiple perspectives; do not treat US/international policy as neutral baseline
⸻
## Communication Style
– Lead with direct answer (AFTER verification for current-period financial queries)
– Structured when useful, minimal formatting
– No hyperbole, marketing language, emojis, throat-clearing, or preamble
– Clarity > style
– Casual chat: empathetic/natural tone, short responses acceptable
### Explanation Style
– Assume competence; direct answer first
– Context/examples as needed; ask probing questions when genuinely useful
– Beginners: simple language but accurate content, no condescension
### Ambiguous Queries
– Ask clarifying questions if missing critical parameters
– Low-stakes queries: proceed with clearly stated assumptions
### Error Handling
**When protocol missed or error made**:
1. Acknowledge failure explicitly: “I made an error: [specific mistake]”
1. Identify mechanism: “This occurred because [root cause]”
1. Explain impact: “This means [consequence of error]”
1. Fully correct: Show all correct steps/calculations
1. Track repeats: “This is the [nth] occurrence of [error type] in this conversation”
**Pattern recognition**: If same error type occurs 3+ times in conversation:
“`
CRITICAL: Repeated [error type] detected.
Switching to [corrective measure] for remainder of conversation.
“`
**Common Error Type**: Presenting unverified financial data
**Prevention**: For current-period financial queries, verification must complete before any specific rates/amounts are stated
**Correction**: If caught mid-response, explicitly state “Correcting: verifying current rates first…” then continue with proper sequence
Never: Minimise, excuse, or downplay errors
Context Management
– Follow latest human instructions over preferences if conflict
– Modified preferences only apply to new conversations
– Do not reference `<userPreferences>` tags or internal structure unless asked
Pattern Recognition
Monitor for:
– Repeated calculation errors → Switch to mandatory analysis tool use
– Repeated verification failures → Provide methodology for user self-verification
– Repeated misclassification → Explicitly state classification reasoning before each response
– Repeated unverified financial claims → Flag and switch to verification-first mode

Here is the agenda for the meeting produced by Iain …
2025-10-09-Apps-Discussion-v03There was quite a lot of discussion on the merits, or otherwise, of Perplexity (or any other ChatBot) being part of a browser – in this case Comet. The group agreed that a session to review and update our knowledge of advances in AI would be timely.
… and the we had the Buzzword “Smart Watches” from Phil …
Smart_WatchesThis BuzzWord created a lot of comment especially on health issues, and we should take seriously the suggestion to ensure our Medical IDs were up-to-date on our smart phones, as well as getting confident about the benefits of using the watch rather than the phone for a lot of everyday tasks. Phil advocated that no one needed more than the entry level iPhone SE – if you were considering an Apple Watch.
The main discussion of the session revolved around “The Apps I use”. I’ll try and write more about these in the Forum Topic that I created for this subject some time ago, so will here just list the apps. The Forum post will have (hopefully) a link to it added …
Helen kicked a lively session off with her use of the Cardiff Bus app which enable her and others to easily see where the bus they were waiting for actually was. It also has good timetables and maps to plan your journey. A well used app by most members of the group, and one that was well appreciated and easy to use.
Renee then highlighted her use of WordReference – an app that works like a dictionary, when you just can’t find the word you’re looking for.
Sianed initiated a bit of a discussion around her use of Waze which she found much better than her satnav and Google Maps for helping her find the best route in the car from A to B, due to it’s crowd-sourcing of road conditions. It’s also a great source of engagement for grandchildren when driving them around as they feed the app with (hopefully) valid information and advise on when there’s a police car hiding!!
Yvonne is very keen on using BBC Sounds – I must get round to using it more, especially as it not only has loads of music on it, but also live streaming of the radio channels, I believe.
Don came up with Bluebirds, an app he’s been encouraged to use now that he’s. season ticket holder at Cardiff City. I think it was him that mentioned Find Me – a location tracker. This then led to mentioning of Life360 and using Find my xxx (if you’re an Apple Family member); all useful apps to track errant children or grandparents!!!
Nita mentioned BusTimes.org, a website that allows you to stack buses all over the country with, it has to be said, a level of inaccuracy, but useful all the same to help you plan a journey. She also mentioned Your Parking Space, an app and website which enables you to book 350000 parking spaces across the UK. This of course kicked off a long discussion of car parking in general, and how awkward it can be to download an app to pay for parking in a location with a poor cell signal. So it might be advisable to download and install Ringo and PayByPhone onto your phone to reduce annoyance and anxiety! An alternative to Your Parking Space is JustPark which I’ve used to book a parking space in someone’s front garden in London. The things you can do!!
Phil mentioned a Paint application on MacOS, similar to the one he’d first used on Windows 95, which was simple to use. I’ve tried to locate it, but so far have been unsuccessful. He also mentioned MusicScore, which was great for music notation scores when it was first launched in that it allowed you free access to music. Things have changed now and it’s not only a subscription service but you also have to pay for downloads.
George then introduced us to two medical devices and their associated software. First he praised the Omron range of devices – blood pressure, weight, temperature, whose results could all be integrated into an app and then downloaded into a spreadsheet or fed to other Health apps. He also described the clever integration of hearing aids with controls on your phone to optimise the listening/hearing experience in different environments. Margaret mentioned her hearing aids were controlled by MyPhoneAK, I suspect there are other apps that do something similar, mine is Hearing Remote.
Margaret then mentioned her use of her Windy app and the website, which gives a visual presentation of how the weather is progressing – strongly recommended to give it a look. I mentioned my use of Yr from the Norwegian weather service which I found particularly useful when travelling. George then added Marine Traffic (for boats) which works in a similar way to Flight Radar – mentioned by Shiela (for commercial airlines) in tracking the whereabouts of boats, and of course in identifying them from out of visual range.
Anne loves the Translate app (Google or Apple), and who doesn’t! You’ll soon be able to have a real-time conversation with someone speaking your collective native languages with spoken translations instantaneously.
Tom highlighted his use of Google’s Notebook LM which he uses for Research and Note Taking and Recall which (if I’ve understood it correctly) can summarise from articles, documents or books into a single “note” and then with Obsidian (a personal knowledge base and note-taking application) store it for you for later reference.
Wordgames, puzzles and assistants were then mentioned by a number of people. Sheila uses Crossword Solver (I’m not sure which one – there are many) to help solve crosswords from known letters. Iain mentioned that he always had to be doing something, so in the blank spaces he would play Solitaire. Phil mentioned that he’d used ChatGPT to solve Sudoku puzzles, and Iain (and others) have used Anagram Solver. [I have to admit this is not, and never will be, an area of interest to me – shame on you, I hear you say!!]
Dave (a self-described petrol-head) uses an application – Torque to help with his rebuilding/restoring of cars beyond their sell-by date 🙂
Phil chipped in with a thumbs up for Tile Tags as a less expensive option to proprietary Apple tag devices, and ExpertRAW was mentioned as an Android alternative to Halide that I mention in my list of Favourite apps.
Lastly, Helen asked if anyone had any thoughts on how to get old family videos that had been transferred onto DVD onto a Digital platform. Tom came back with a really useful suggestion – using MakeMKV from a DVD player on your computer. I think that (with perhaps an introductory session on video-editing might be a good idea for a practical session at some time in the future.
Unfortunately I was on holiday in sunny Salcombe for this meeting and Iain stepped in with a presentation on Deconstructing TV …
2025-09-25-Deconstructing-TV-v3
… I’m sure you all enjoyed it. I gather that ideas for future meetings were also discussed. One of which will be the subject of discussion on the 9th October – Favourite apps.
In addition to Iain’s presentation, Phil provided a Buzzword – revealing the mysteries, and machinations of Buzzwords …
2025-09-25-QR_Codes
Following the meeting Phil posted to the Artificial Intelligence Forum his experience of using ChatGPT to help him revive a sad Christmas Cacti. I encourage you to look at the post, and I furthermore encourage all of you looking to see if you could add some selections, experiences, thoughts and ideas to a Forum as a Topic that others might be interested in.

o Presentation on TV in our lifetimes – the impact of digitisation by Iain King
It was one of these three, I think probably the middle one …



… that kicked off my interest in computing. Of course these were very much analog mechanical calculating machines, and I never got the hang of how to use them however hard I tried in the Statistics Practical labs at UCW Aberystwyth in the period 1969-70, but they did revive my interest in mathematics which I’d had to drop as an ‘A’ Level subject, and soon after, multi-variate statistics became my focus for much of the next 10 years as I struggled to complete (#fail) a PhD.
However, when we went through the induction course and were told that we should sign-up for a course on programming in Wirth’s Algol 60, I didn’t delay. The die was cast, my future was sealed. I spent the next three years learning Fortran IV, then Dartmouth Basic (used on Teletypes) to submit jobs to the Elliot 4130, later a ICL 190x that the Computer Centre had. My data sets were so large I had to submit jobs to the Regional Computing Centre at Manchester which meant I had to work every evening to get the data set correct, then submit the job through a landline (modem connection) so that it ran through the night and returned the job the next day for me to print out the results and prepare my data set, or change the algorithm, for the next nights job. Oh happy days!!! Oh to be so young and energetic again!!!
Later when abandoning my lecturing role at a College of Education I did a MSc Computer Science conversion course at Bradford where I was given a Digital Equipment PDP 11/60 to play with and build my own Disk Operating System (Modos) using another of Wirth’s programming languages – Modula. He went on to develop Ada which was widely adopted in the defence and general scientific community. So that led me into Systems Programming.
I returned to Cardiff in 1981 at what was then South Glamorgan Institute of Higher Education as Systems Programmer for their brand new Prime 500 computer and had to learn a new operating system – Primos, and new programming languages – PLP (as well as using my Fortran experience).
Latterly as computing developed and fighting for time-share and batch-processing came to be a thing of the past – much as mechanical calculating machines had disappeared – I embraced the internet in the early 1990’s. I created the first website for what had become UWIC, and had learnt a fair bit about HTML, and scripting.
It all went downhill from then on as management responsibilities took over and programming became a thing of the past. Of course I do still dabble, but really – it’s way beyond me, as my eldest son tells me on more than one occasion.
I await your contributions, which I’d like to record. We did something like this once before during Covid times on Zoom, in 2025, and several of us wrote “our encounters” up for Thought grazing.
I wrote the following post …
We had a number of other contributions, from Margaret …
… from David Hughes …
… from Paul de Guess …
… and from Renee …
There were many other amusing and interesting contributions, so we felt it worthwhile to kick the new year off with a trip down memory lane. Enjoy.
Here’s the audio recording. I’m afraid the transcript is far from perfect, and life is too short to go in and edit it …

Thanks to Cortical Silence for this week’s edifying message 🙂
