Forty years ago today, a new type of personal computer was announced that would change the world forever. Two years later, it was almost completely forgotten.

The Apple Lisa started in 1978 as a new project for Steve Wozniak. The idea was to make an advanced computer using a bit-slice processor, an early attempt at scalable computing. Woz got distracted by other things, and the project didnt begin in earnest until early 1979. Thats when Apple management brought in a project leader and started hiring people to work on it.

Lisa was named after Steve Jobs daughter, even though Jobs denied the connection and his parentage. But the more interesting thing about the Lisa computer was how it evolved into something unique: It was the first personal computer with a graphical user interface (GUI). The vision takes shape

GUIs were invented at Xeroxs Palo Alto Research Center (PARC) in the early 1970s. The Alto workstation, which was never sold to the public, had a bitmapped screen that mimicked the size and orientation of a piece of paper. PARC researchers wrote software that displayed windows and icons, and they used a mouse to move a pointer on that screen. Enlarge / A restored Xerox Alto, still running code in 2017. Ken Sheriff

Jef Raskin, an early Apple employee who wrote the manual for the Apple ][, had visited PARC in 1973. He believed that GUIs were the future. Raskin managed to persuade the Lisa project leader to change the computer into a GUI machine. However, he couldnt convince Jobs, who thought Raskin and Xerox were incompetent.

Raskin altered his approach and got graphics programmer Bill Atkinson to propose an official tour of PARC in November 1979. Because Jobs thought Atkinson was great, he agreed to come along. Jobs visit to PARC became the stuff of legend, a tale of a brilliant visionary seeing the future of computing for the first time. But in reality, Atkinson was already working on LisaGrafthe low-level code that would power the Lisas GUImonths before Jobs saw the PARC demo.

The Lisas hardware changed as well. The team abandoned the bit-slice processor and adopted Motorolas new 68000 CPU. The 68000 was a 16/32-bit chip and used a 24-bit address bus, giving it a maximum of 16 megabytes of memory. This was fine, as memory prices were still sky-high in 1980, and most computers of the day had a maximum of 64 kilobytes of RAM.

In January 1981, senior leadership at Apple got tired of Jobs constant interference and micromanagement of the Lisa project and officially removed him from the team. Jobs seethed, then took over a smaller skunkworks project being run by Raskin. This would become important later. Advertisement

By early 1982, the Lisa hardware was mostly finalized. However, the software was still in flux. A team of designersincluding Larry Tesler, who had left PARC to join Applehad been busy doing tons of research, prototyping, and testing. The main question they had was: How should the Lisas GUI actually work? June 1979: A mockup of an early Lisa interface, running on an Apple ][. Interactions magazine August 1980: A mockup of menus and dialog boxes, running on a Lisa prototype. Interactions magazine October 1980: A mockup of the new single menu bar. Note the Note from Jef. Interactions magazine December 1980: An abandoned multi-column file browser. This design would return in NeXTstep and OS X. Interactions magazine July 1981: The Twenty Questions file locator. It worked, but nobody found it fun, so the team returned to the icon-based approach. Interactions magazine August 1982: The Lisas GUI is finally finalized. Interactions magazine

In an article in Interactions magazine, designers Roderick Perkins, Dan Smith, and Frank Ludolph described how the Lisas interface changed from early prototypes to a familiar desktop with icons, then away from that model, then finally back to an icon-based, document-centric approach. The goal was to make the Lisa powerful and fun to use.

At long last, the Lisa was ready to be unveiled to the public. On January 19, 1983, Apple announced the computer, which it accurately described as revolutionary.

Surprise rise in inflation as summer travel pushes up air fares

Surprise rise in inflation as summer travel pushes up air fares

Prices in the UK rose even faster than expected last month, reaching the highest level in 18 months, according to official figures.

Inflation hit 3.8% in July, data from the Office for National Statistics (ONS) showed.

Not since January 2024 have prices risen as fast.

It’s up from 3.6% in June and is anticipated to reach 4% by the end of the year.

Economists polled by Reuters had only been expecting a 3.6% rise.

More unwelcome news is contained elsewhere in the ONS’s data.

Train tickets

Another metric of inflation used by government to set rail fare rises, the retail price index, came in at 4.8%.

It means train tickets could go up 5.8% next year, depending on how the government calculate the increase.

This year, the rise was one percentage point above the retail price index measure of inflation.

These regulated fares account for about half of rail journeys.

Why?

Inflation rose so much due to higher transport costs, mostly from air fares due to the school holidays, as well as from fuel and food.

Petrol and diesel were more expensive in July this year compared to last, which made journeys pricier.

Coffee, orange juice, meat and chocolate were among the items with the highest price rises, the ONS said. It contributed to food inflation of 4.9%.

What does it mean for interest rates?

Another measure of inflation that’s closely watched by rate setters at the Bank of England rose above expectations.

Core inflation – which measures price rises without volatile food and energy costs – rose to 3.8%. It had been forecast to remain at 3.7%.

It’s not good news for interest rates and for anyone looking to refix their mortgage, as the Bank’s target for inflation is 2%.

Whether or not there’ll be another cut this year is hotly debated, but at present, traders expect no more this year, according to data from the London Stock Exchange Group (LSEG).

Economists at Capital Economics anticipate a cut in November, while the National Institute of Economic and Social Research (NIESR) expect one more by the end of the year.

Analysts at Pantheon Macroeconomics forecast no change in the base interest rate.

Political response

Responding to the news, Chancellor Rachel Reeves said:

“We have taken the decisions needed to stabilise the public finances, and we’re a long way from the double-digit inflation we saw under the previous government, but there’s more to do to ease the cost of living.”

Shadow chancellor and Conservative Mel Stride said, “Labour’s choices to tax jobs and ramp up borrowing are pushing up costs and stoking inflation. And the Chancellor is gearing up to do it all over again in the autumn.”

AI ‘immune system’ Phoebe lands backing from Google arm

AI 'immune system' Phoebe lands backing from Google arm

An AI start-up which claims to act as an ‘immune system’ for software has landed $17m (£12.6m) in initial funding from backers including the ventures arm of Alphabet-owned Google.

Sky News has learnt that Phoebe, which uses AI agents to continuously monitor and respond to live system data in order to identify and fix software glitches, will announce this week one of the largest seed funding rounds for a UK-based company this year.

The funding is led by GV – formerly Google Ventures – and Cherry Ventures, and will be announced to coincide with the public launch of Phoebe’s platform.

It is expected to be announced publicly on Thursday.

Phoebe was founded by Matt Henderson and James Summerfield, the former chief executive and chief information officer of Stripe Europe, last year.

The duo sold their first start-up, Rangespan, to Google a decade earlier.

Their latest venture is motivated by data suggesting that the world’s roughly 40 million software developers spend up to 30% of their time reacting to bugs and errors.

Financial losses to companies from software outages are said to have reached $400bn globally last year, according to the company.

Phoebe’s swarms of AI agents sift through siloed data to identify errors in real time, which it says reduces the time it takes to resolve them by up to 90%.

“High-severity incidents can make or break big customer relationships, and numerous smaller problems drain engineering productivity,” Mr Henderson said.

“Software monitoring tools exist, but they aren’t very intelligent and require people to spend a lot of time working out what is wrong and what to do about it.”

The backing from blue-chip investors such as GV and Cherry Ventures underlines the level of interest in AI-powered software remediation businesses.

Roni Hiranand, an executive at GV, said: “AI has transformed how code is written, but software reliability has not kept pace.

“Phoebe is building a missing layer of contextual intelligence that can help both human and AI engineers avoid software failures.

“We love the boldness of the team’s vision for a software immune system that pre-emptively fixes problems.”

Phoebe has signed up customers including Trainline, the rail booking app.

Jay Davies, head of engineering for reliability and operations at Trainline, said Phoebe had “already had a real impact on how we investigate and remediate incidents”.

“Work that used to take us hours to piece together can now take minutes and that matters when you’re running critical services at our scale.”

Paul Weller suing former accountants after they stopped working with him over Gaza statements

Paul Weller suing former accountants after they stopped working with him over Gaza statements

Paul Weller is suing his former accountants after they stopped working with him after he alleged Israel was committing genocide in Gaza, according to a legal letter.

The former frontman of The Jam, 67, has filed a discrimination claim against Harris and Trotter after the firm ended their professional relationship.

Lawyers for Weller say the singer-songwriter was told in March that the accountants and tax advisers would no longer work with him or his companies.

According to the letter, which was seen by the PA news agency, a WhatsApp message from a partner at the firm said: “It’s well known what your political views are in relation to Israel, the Palestinians and Gaza, but we as a firm are offended at the assertions that Israel is committing any type of genocide.

“Everyone is entitled to their own views, but you are alleging such anti-Israel views that we as a firm with Jewish roots and many Jewish partners are not prepared to work with someone who holds these views.”

Israel has vehemently denied claims of genocide.

But lawyers for Weller claim by ending their services, the firm unlawfully discriminated against the singer’s protected philosophical beliefs, including that Israel is committing genocide in Gaza and Palestine should be recognised as a nation state.

Weller said: “I’ve always spoken out against injustice, whether it’s apartheid, ethnic cleansing, or genocide. What’s happening to the Palestinian people in Gaza is a humanitarian catastrophe.

“I believe they have the right to self-determination, dignity, and protection under international law, and I believe Israel is committing genocide against them. That must be called out.

“Silencing those who speak this truth is not just censorship – it’s complicity.

“I’m taking legal action not just for myself, but to help ensure that others are not similarly punished for expressing their beliefs about the rights of the Palestinian people.”

The legal letter says Weller will donate any damages he receives to humanitarian relief efforts in Gaza.

Cormac McDonough, a lawyer at Hodge Jones and Allen, which is representing Weller, said his case “reflects a wider pattern of attempts to silence artists and public figures who speak out in support of Palestinian rights”.

Mr McDonough added: “Within the music industry especially, we are seeing increasing efforts to marginalise those who express solidarity with the people of Gaza.”

Sky News has contacted Harris and Trotter for comment.
