Korea does this, also. Sometimes I'll get confused at a restaurant or other sign that is just 2x2 array of syllables. Is this horizontal or vertical? Even more confusing is when it can be sensibly read either way.

In the mid-90s I taught a night class on Unix, and was experimenting with shell scripts from The Unix Programming Environment. There was an example using a loop and the who command to alert you when someone logged onto your local system. My

At first, I thought you meant restaurants which had a big scrolling ticker along the wall so patrons could watch the market while they dine.

yep, I see those often here -- scary. Another sofa-related irony is that a lot of Koreans don't actually sit on their sofas. Rather, they sit on the (heated) floor and use the sofa as a back rest. https://koreajoongangdaily.

I felt the same way. At some point shortly after graduation, I found a heavy plastic Smith chart that was designed to be written on with a grease pencil, and erased with a cloth when you're done.

I just did a spot check, since I live very near an airport. The airport is blurred / obscured on Naver and Kakao Maps. Google maps and Google Earth still show the actual imagery. I guess Google's blurring hasn't begun yet.

Most of our professors did allow them. As they explained their reasoning, the information you could store in your calculator memory at that time was roughly equivalent to what you could write on a single piece of paper. So they would usuall

I have a product labeled Boogieboard that I bought on a whim at Costco years back. I want to say it was less that $10? Really simple, no connectivity, it does really seem like an etch-a-sketch with a stylus instead of knobs. Stuck it on the

A long time ago, a colleague and I visited a supplier in another state. While we were waiting alone in a conference room, we noticed an unusual looking note taking device at the front of the room. It was a very large easel that looked like

When I first was exposed to Lynx, I was also working on a project using the Lynx realtime Posix OS. To my knowledge, the two aren't related other than by name. I checked a couple of years ago, Lynx OS still exists but under a different

Here in South Korea, everyone who uses online banking has to renew and reissue banking certificates every year. While I'm not convinced the certificate process is 100% safe, using certificates is one good concept in the sh*t show of Ko

I've used that article several times in the past. I'll also note that many years ago, on projects which were not cost sensitive, we would often use the MC14490 IC for hardware debouncing (mentioned in part 2 of this article).

I live less than a km from a small airport in South Korea, and hear that "cannon" going off all the time. Now I'm curious, is it propane or a person? I'm going to be on the lookout now.

One report I read here (I'm in South Korea) said the gear was down for the first aborted attempt and were then retracted for the go-around. I can't remember where I read that, however.

It makes sense that new rules should apply to newly made/sold phones. Why not grandfather existing phones? Isn't any communication better than none in an emergency? A working phone, even if it doesn't support placing official

That makes sense. So perhaps the immediate impact on operations on election day coverage / reporting is more symbolic than real?

I think why this has always stuck in my craw is that a compiler can complain if the result and operands aren't the same size. But if they ARE the same size, the compiler doesn't similarly complain "your result may overflow th

Yeah, I get that. Existing hardware supports double-width integers for multiplication (`u16 = u8 * u8`, etc ). But for addition, typical ALUs don't support oddball widths like (`u9 = u8 + u8`, etc). And then what do you about chaining

I've always wondered why programming languages define that mathematical operations should result in the same type as the operands. But this isn't true, mathematically.
