Larry Tesler, an icon of early computing, has died at the age of 74.

Mr Tesler started working in Silicon Valley in the early 1960s, at a time when computers were inaccessible to the vast majority of people.

It was thanks to his innovations – which included the “cut”, “copy” and “paste” commands – that the personal computer became simple to learn and use.

Xerox, where Mr Tesler spent part of his career, paid tribute to him.

“The inventor of cut/copy & paste, find & replace, and more, was former Xerox researcher Larry Tesler,” the company tweeted. “Your workday is easier thanks to his revolutionary ideas.”

Mr Tesler was born in the Bronx, New York, in 1945, and studied at Stanford University in California.

After graduating, he specialised in user interface design – that is, making computer systems more user-friendly.

He worked for a number of major tech firms during his long career. He started at Xerox Palo Alto Research Center (Parc), before Steve Jobs poached him for Apple, where he spent 17 years and rose to chief scientist.

After leaving Apple he set up an education start-up, and worked for brief periods at Amazon and Yahoo.

In 2012, he told the BBC of Silicon Valley: “There’s almost a rite of passage – after you’ve made some money, you don’t just retire, you spend your time funding other companies.

“There’s a very strong element of excitement, of being able to share what you’ve learned with the next generation.”

‘A counterculture vision’

Possibly Mr Tesler’s most famous innovation, the cut and paste command, was reportedly based on the old method of editing in which people would physically cut portions of printed text and glue them elsewhere.

The command was incorporated in Apple’s software on the Lisa computer in 1983, and the original Macintosh that was released the following year.

One of Mr Tesler’s firmest beliefs was that computer systems should stop using “modes”, which were common in software design at the time.

“Modes” allow users to switch between functions on software and apps but make computers both time-consuming and complicated.

So strong was this belief that Mr Tesler’s website was called “”, his Twitter handle was “@nomodes”, and even his car’s license plate was “No Modes”.

Silicon Valley’s Computer History Museum said Mr Tesler “combined computer science training with a counterculture vision that computers should be for everyone”.

Back to school plan a potential boon for hard-hit Labrador, say MHAs




After months of grappling with province-wide education restrictions, Labrador students — and their largely exhausted parents — could see relief in September, regional MHAs say.

What works on the island doesn’t work in more remote parts of the province, Torngats MHA Lela Evans told CBC News on Tuesday.

As students hunkered down to study from home computers in March, treacle-slow Internet speeds, even in more populated areas of Labrador, made online classes an impossibility for some students, she said.

“We have not had investment in our infrastructure that is successful,” Evans said, referring specifically to Internet connectivity along the north coast. “We have not had things that other people in the province have access to.”

Her concerns were previously echoed by families across Labrador struggling with virtual classrooms. 

Spotty Internet connections also mean the province’s $20-million earmarked for September spending on laptops and other distance learning equipment won’t be of much use, she said.

Lake Melville MHA Perry Trimper pointed out one potential back-to-school bright side.

The province’s return-to-school plan announced Monday, which designates in-person learning as the ideal scenario, allows for that in-class instruction to be considered on a regional basis.  That means an outbreak on the island won’t necessarily send kids in Labrador packing.

“The premise is that even if we have [COVID-19 cases] in St. John’s, kids probably still go to school in Makkovik or in Happy Valley-Goose Bay,” he said.

Slew of hardships

The regionalized model was championed by the province in Monday’s report as a way to provide “consistency, stability and equity” for students and avoid province-wide closures.

 It could act as beacon for a region with increased infrastructure difficulties in recent days, including Air Canada’s decision to end many of its flight routes to Labrador and long wait times for ferry reservations along the north coast.

Woodward Group, which operates the Kamutik W that serves six northern communities, said in a statement Thursday that passenger capacity has been severely curtailed by Transport Canada restrictions, and that some passengers “won’t be able to move” between ports.

That leaves many Labradorians facing increased travel costs.

Evans said the disparity between opportunities in remote communities and populated areas, in terms of travel, education and the cost of living, has only been highlighted by COVID-19.

“People are getting tired of hearing about it, but this pandemic is really showing the problems that we’re facing,” Evans said. “In terms of the internet speed, in terms of food security, in terms of all the resources.”

On Thursday, the province announced a one-time $250 pandemic relief grant for households in nine Labrador communities to offset some of the incurred costs of COVID-19 restrictions.

COVID-19 on P.E.I.: What’s happening Sunday, July 12




The ferry service between Prince Edward Island and Nova Scotia is back on schedule again after some crossings were cancelled Saturday.

Northumberland Ferries said the cancellations were caused by a technical issue with the shore ramp for the MV Confederation at Wood Islands.

The ferry service began six daily round-trip crossings from Wood Islands to Caribou, N.S., when the Atlantic bubble began July 3.

The downtown farmers market, held outdoors on Queen Street in Charlottetown, opens for the season today from 11 a.m. to 4 p.m.

To accommodate the market, Queen Street will be closed between Grafton Street and Sydney Street every Sunday from 7 a.m. until 5 p.m., through to Sept. 27.

After being postponed for more than two months due to the COVID-19 pandemic, the 2020 East Coast Music Awards took place on July 11 as a special pre-recorded broadcast. The East Pointers from P.E.I. won for songwriter of the year and contemporary roots recording of the year for Yours to Break.

With COVID-19 shutting down Islanders’ plans for summer travel, at least outside the Atlantic provinces, a lot of people are looking for things to do. Some shared their summer bucket lists.

Fabric stores on P.E.I. are seeing an increase in business as more people are making their own face masks to help stop the spread of COVID-19.

Health PEI told employees in an email earlier this week that all staff who come in contact with patients and who aren’t able to physically distance must now wear medical masks. Officials say the province has enough masks to last eight or nine weeks, if staff use an estimated 100,000 masks per week.

Education Minister Brad Trivers gave more details to CBC News on how schools will operate in the fall — students will not be required to physically distance in classrooms or on buses, he said, but may have to wear face masks in hallways.

P.E.I. has had a total of 33 COVID-19 cases, with 27 considered recovered.

RECA Changes Announced – Real Estate and Construction




To print this article, all you need is to be registered or login on

On June 3, 2020, major changes were announced to theReal
Estate Act
, the legislation that governs realtors, mortgage
brokers, appraisers, and property managers in Alberta. The changes
stem from a 2019 KMPG review which criticized RECA’s former
counsel, following which the council was dismissed and an
administrator was appointed.

While most of changes relate to governance and oversight of
RECA, of particular note to condominium managers is that they will
officially be managed under RECA. The timeline to complete that
process remains unclear as as it depends on how quickly RECA
develops manager licensing requirements.

Another major change for realtors, brokers and managers is that
RECA will not longer be offering educational requirements.
Education will be provided through qualified third parties.

Further changes are summarized below.

Industries Regulated by RECA

  • Condominium managers will be
    regulated by RECA (once the licensing process is developed)

  • Appraisers will no longer be
    regulated by RECA but still must belong to one of three other
    appraisal industry associations

  • All property management, including
    condominium management will be considered a separate activity (not
    as a “trade in real estate”)

Mandate and Education

Ove the next two years, RECA will transition out of providing
licensing education.RECA will now focus onlicensing and
Industry Councils will set out education
requirements and third party providers will provide education.


RECA’s governance will now be split into:

  1. a)a Board of Directors responsible
    for running RECA composed of one member appointed from each
    Industry Council (below), three public members appointed by the
    Minister and a Chair, to be one of thepublicmembers;

  2. b)four separate Industry Councils,
  1. Residential Real Estate

  2. Commercial Real Estate and Commercial
    Property Management

  3. Residential and Condominium Property
    Management; and

  4. Mortgage Brokers

Industry Councils will be made up three elected industry
members, two public Members appointed by the Minster, and a chair
to be elected within each Industry Council.

Bylaws and Rules

RECA bylaws will be passed by the Board of Directors. Industry
Councils will then set rules to establish industry standards
including education and licencing requirements for their

Roles and Responsibilities

The Executive Director will be responsible for the
administration of RECA, including hiring of a Registrar who will be
responsible for investigations and enforcement. Annual performance
reviews will be conducted for both the Registrar and the Executive
Director. The RECA bylaws will separate roles of the Board, the
Industry Councils, the ED and the Registrar.

Dispute Resolution

To reduce internal conflicts and limit legal expenses, a dispute
resolution will be put in place for the Board and Industry Council
members by the Board that will be used if:

  • a Board Member or Industry Council
    Member has allegedly engaged in a prohibited act under the Real
    Estate Act or

  • if there are conflicts within
    Industry Council, within the Board or between a Board and an
    Industry Council

Prohibited actions include using confidential information for
personal gain, impeding the purposes of the Board or Industry
Council, breaking rules for their industry in the course of
business. Members may be suspended during the dispute resolution
process or removed is it is determined they violated the Act.

Lifetime Withdrawals

Industry Council will not be allowed to accept a withdrawal if
allegations of fraud or criminal activity have been made that
warrant an investigation. This is to ensure these allegations are
fully investigated and referred to the appropriate authorities.

Government Intervention/Oversight

After a review, the Minister will have the power to dismiss
Board members, Industry Council members, or employees if the review
support this action, without further Order. The Minister will be
able to issue orders for RECA to take specific action without doing
a review first.

New Transparency Requirementsfor minutes,
agendas, salaries/honoraria and disclosure of annual business plan
