Took the afternoon off to do kid wrangling because the school is closed from the heat (trading with other families who take over kid wrangling other days this week) and I think that is my first “climate day” as a reason for not working?

By far the best strategy for Canada is, and has always been to win by helping America win. The best way is to be strong, sovereign, hard-working and deeply competent. Ideally with an uncanny ability to start ambitious infrastructure projects and finish them on budget and on time. Shout-out to our nuclear energy sector for nailing that. Do that and every other problem melts away. Europe, and everyone else, will be happy trading partners. energy Europe Related

My thoughts are with their families and all those who have been affected by the attack.

A Monday morning question for you: I'm not usually awake from 5am to 6am, but when I am I tend to enjoy it. Start the day slow. Watch the sunrise. Get a few things done before everyone else wakes up. Meanwhile, I am often awake from 10pm to 11pm and I find that I tend to use it poorly. Passively watching TV or scrolling on a screen. Late-night snacking. Generally focusing on things that are fairly unimportant. Trading the last hour of the night for the first hour in the morning would be a pretty high-value trade for me. Which hours of your day tend to return the most value and which ones tend… Related

No child should be raised in a hostel room. And no family should wait ten years for a front door of their own. Today we’re announcing funding for the biggest council housebuilding comeback in decades. Nearly £10 billion will go to councils and housing associations to build genuinely affordable homes, most of them for social rent. This funding will directly help families trapped in temporary accommodation or stuck on housing waiting lists into safe, secure homes. Related

This was the first year in a long time that the US stock index (VTI) got trounced by International stocks (VXUS). I was shocked by this difference: VTI: +18.6% VXUS: +33% (!!) This was good for my @Betterment account, which holds about an allocation of non-US stocks and has thus lagged a US-only portfolio for a while. Even after this run, VXUS is much cheaper, trading at a P/E ratio of 17 (and paying a 3.6% dividend) versus our ~27 ratio for the US index which a paltry 1.1 dividend. Will the outperformance continue in the coming years to help these two competitors even back out? Historically… Related

What is a korrent?
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
