Possibly because your 37.5 is from your body trying to reach 38 but not getting there yet. I'm just recovering from influenza right now and over the past two weeks I've noticed that pattern very clearly -- I feel worse when my te

Outside of the City of Vancouver, yes. Metrotown, Brentwood, Lougheed, Surrey City Center -- but Vancouver itself has been very resistant to development outside of the core. The story of Metro Vancouver development can be summarized as &qu

I'm guessing you were downtown? From roughly 15th south -- the majority of the city -- pretty much all you get is suburban wasteland of detached homes.

Any biochemists here who want to speculate about potential mechanisms? I can't help thinking about the connection between potassium and insulin -- insulin pushes potassium into cells, to the extent that insulin is the standard treatme

I wholeheartedly support the elimination of harmful languages. There's just no good reason these days for anyone to use C++.

I've been around all this time -- in fact, I work from home while my wife goes out to work -- but that doesn't change the fact that I'm the mean parent who doesn't give her milk. I think the big change a few weeks ago wa

To be clear, the only physical restraining I do is "Mommy needs to go to work now so Daddy is going to pick you up so you don't try to chase her down the stairs". She knows she can't walk down the stairs on her own but

isn't part of the point of SHA2 that it's more ARX-y? I don't know that the NSA has ever published the internal discussions which resulted in SHA2, but I always thought the primary design purpose of SHA2 was to produce larg

I guess it's a matter of how strongly you interpret the word "significant". There's absolutely a difference between SHA1 and SHA2 which results in the attack not working; but I'd personally characterize it as a min

The SHA1 break doesn't threaten SHA2. The two hashes are different in a significant way that breaks the SHA1 attack. Hmm, I think you might be overstating this a bit. While the SHA1 attack indeed does not break SHA2, the whole reaso

The gold standard is "separated twins" studies, looking at identical twins who are adopted away to different families at birth. Sadly for science but happily for the families involved, these are getting harder to do; the primary s

All you know for certain is that you didn't cheat and your twin claims that he didn't copy your work. ;-)

The ones in Vancouver, yes. Not so much in the suburbs, and despite the name there were more Vancouver Specials built outside of Vancouver than inside.

The first generation of Vancouver Special owners were largely families who occupied the entire property. By the late 90s either their kids had moved out and they had space to spare or they sold their homes (at much higher prices!) to famil

Not the house itself! A typical property tax assessment on a Vancouver Special is $2M of land and $50k of building.

A few details not mentioned in the article: 1. The Vancouver Special originated as a way to evade zoning regulations. The lower floor is 18" below grade which qualified it as a "basement" not counting towards floor area rati

The smallest percentage for "needs improvement" ratings I was expected to hit was 5%, the largest was 15%. How do you do that if you're managing a team of 5? Any manager with an employee who had two connective needs improv

The problem here is "turn out to". Documents in a safe deposit box might well be privileged but not in an obvious way because nobody expects their safe deposit boxes to be searched by the FBI. The FBI may have seized privilege

It's in plain sight once there's a legal justification for opening the box.

There's well defined procedures for searches which may run into privileged materials, yes. In the case of searching law offices, the first step is "don't do this if there's any way you can possibly avoid it". If a

Never mind murder confessions -- what happens if there's legally privileged information in a safe deposit box? Seizing documents without providing any opportunity to litigate privilege is a legal Pandora's box.

The hamburger buns contain both corn syrup and sucralose (splenda). I really wonder what the rationale is. They want to make the buns tasty but don't want too many calories. Makes sense to me.

If you're scrolling a document, the most recently revealed line is always at the bottom, which is often the least visible part of the screen if you have a large audience.

I didn't forget it, and it's one of my favorites too -- but I don't know if it qualifies as the most impactful. People who use it love it, but it's not very widely used compared to, say, bsdiff.

Probably bsdiff; a few hundred lines of code hacked together over a weekend has saved people over a hundred thousand years of waiting for software updates to download. Next up is probably scrypt; it would rank higher if cryptocurrencies use

As a code reviewer, I love seeing comments like that, because it immediately flags "someone made a mistake here". Sure, sometimes the code is right and the comment is wrong -- but sometimes the comment is right and the code is w
