> x86 is notable in that you can cause a branch or jump without calling a branch or jump instruction.

I'm curious what you are referring to here. Are you talking about CMOV? Or INT/SYSCALL/SYSENTER? Or just the ability to trigger a fault handler? Or semantic games like push followed by ret?

Not disputing this, but the UX of navigating to a bank's website using Chrome on XP and getting redirected to a "Download Chrome" link when there isn't a newer version for your OS isn't a great experience either.

Less effective at cooling, more effective at dehumidifying (it seems there is a presumption that dehumidification is roughly linear with operating time.)

For N=104, if you look at the PDF and zoom in, you can see the blue circles have a line rather than a dot. Admittedly, it is hard to see why the blue circles do not have enough freedom to move slightly away and become magenta (particularly the one on N=108).

> So they have a duty to select a CEO who doesn't enable the unnecessary waste of corporate money on optional taxes.

Waste is one of a very short list of categories that are considered something no one wants: https://medium.com/bull-market/there-is-no-effective-fiducia...

That might be true, but the reason for this recommendation is because botulism spores can exist in honey and the systems (mostly gut bacteria, from what I understand) of infants are not developed enough to deal with it, unlike older children and adults.

AFAIK, spores have not been observed in US-sourced honey, but that is no guarantee.

This particular item does not appear to be well made, which lends credence to the difficulty of finding a high quality product.

I basically gave up on twitch after it stopped working on the Xbox 360. The app just shows thumbnails but never streams. It doesn't work right in the browser for me either, probably due to running an old version of Chrome, but it used to work, and the browser hasn't changed, so I blame site "upgrades" (read: changes that break what was previously working.)

The paper talks about dynamic networks where nodes are being added or removed. If m and k are fixed, does it set an effective upper bound on the number of nodes? How do you address the possibility of multiple nodes having colliding hash values?

If you have array @foo in perl, $#foo is the index of the last element of the array, which is just the size of the array -1. So if @foo is undefined, $#foo is -1.

Using a variable instead of 'foo' is a symbolic reference, so this is effectively using the symbol table as the associative array. This means that this solution also gets it wrong if your file contains a line that matches the name of a built-in variable in perl. That would be tough to debug!

If your file contains

    This is the first line of the file

then during execution of

    ++$#$_

the result is the same as if you had written

    ++$#{This is the first line of the file}

So the variable @{This is the first line of the file} goes from undefined to an array of length 1, turning $#{This is the first line of the file} to 0.

Incidentally, this is why the snippet fails to work for a line repeated more than once: for each occurrence of the expression, the value returned is in the sequence -1, 0, 1, 2, 3, ... so it is only false for the second occurrence.

Using preincrement instead of postincrement means the values returned are 0, 1, 2, 3, ... which means that inverting the test makes it false for every occurrence after the first.

It is much older than that: https://en.wikipedia.org/wiki/Bell,_book,_and_candle

I believe in contemporary use it has become associated with witches, and I have seen it used as a general "occult" reference.

The popularity of lobster is generally attributed to it being canned and served on the railroads (thinking that they could get away with serving cheap meat to customers in the midwest unfamiliar with it) and then people developing a taste for it.

Calculator is interesting in that there is a physical button on (many) keyboards to open it. Ironically enough, I encountered a bug with the Windows 10 calculator that caused it to crash upon opening: the window would draw, then a second later vanish.

Turned out that it was due to something profile related: re-registering the Windows App Store fixed the issue. Yes, that's right, a dependency on the app store can prevent you from running Calculator.

I remember getting a free polo shirt with the AltaVista logo embroidered on it. I don't recall the specific circumstances that led to being sent a shirt, and I wore holes in it so I no longer have it, but it really was superior to the alternatives before Google came along.
