Does anyone know what kind of bar code this is? What should I do a search for?

@adrianh I have a clear memory of my father going to his office one day to order his medical supplies for the next month.

"They've redesigned the web site!" ... he called to us.

"How does it look?" asked my mother.

"Really good" he replied.

She followed up ... "Can you find what you need?"

There was a long pause.

...

"No".

@cstanhope Absolutely.

Sometimes I look at how convinced some of them are that they must be right, based on their extensive experience of programming, and their clearly impeccable reasoning, and wonder if I am similarly afflicted with an excessive confidence in my abilities.

It serves as a warning ... I hope I heed it well enough and often enough.

That said, some of the people there are stunningly good. I hope *that* judgement isn't based purely on whether they agree with me.

Quoting:

"I learned this week that you can put
our troops’ lives in danger,
compromise our national security,
and violate the Espionage Act. And
the government will do nothing.
But if you write an editorial for your
school newspaper that Trump
doesn't like, you will be abducted on
the street and disappeared."

"You can't have everything ... where would you put it?" -- Steven Wright

"No amount of evidence will ever persuade an idiot." -- Mark Twain.

"To announce that there must be no criticism of the president, or that we are to stand by the president, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public."

-- President Theodore Roosevelt

Is there a non-USA based alternative to DropBox?

Or indeed, any alternative at all?

@cstross I would recommend it.

There is a saying: There is no such thing as bad weather, just inappropriate clothing.

But as my friend @pozorvlak says:

"Sometimes the appropriate clothing is *building*".

"Explanations exist; they have existed for all time; there is always a well-known solution to every human problem—neat, plausible, and wrong." -- H. L. Mencken in "Prejudices: Second Series"

"We are all time travelers, journeying together into the future. Let us work together to make that future a place we want to visit." -- Stephen Hawking

OK, here's a nice variant:

"You are playing the Monty Hall problem. However, you secretly know one of the goats is the former pet of an eccentric billionaire who lost it and is willing to pay an enormous amount for its return, way more than the car is worth. You really want that goat.

"The host is unaware of this. After you pick your door, as is traditional, the host opens one door, which he knows doesn't have the car. He reveals a goat, which you can tell is the ordinary goat and not the secretly valuable one. The host offers to let you switch doors.

"Should you?"

Amazing human being.

@lambdasierra @david_chisnall In "The Moon is a Harsh Mistress" they mention "loglan" (which is now lojban).

There are some who think that would do the job.

I've been thinking about this for ages, but never had the time to craft the words around it.

People keep saying that "Maths should be fun" ... and I push back with "It should be engaging ... 'fun' is a different thing.

So @rakhichawla has posted pretty much exactly this, but better than I ever could.

I'm copying it here with permission.

Please read this, then as it says at the end ... let's have a deeper conversation about this ...

(PS: I'd love this to get boosted to get outside my bubble ... you're all amazing, but there will be other opinions, and other thoughts that could be helpful or valuable)
