Back in college I used to know a guy who had eyebrows shaped like a rainbow and set very high up his forehead. His brows made his face look perpetually amazed at something. Although his brows did make his face look very handsome. In trying to solve one problem with plastic surgery you might end up with another :)


As an ESL I can tell you that it also depends on your exposure to English. Non-native English speakers are often taught and exposed to mostly (classical) literary works and/or formal speak (for example, math and science). It's one of the reasons why their speech might sound stilted in person, but "perfect" in writing. What you think is "colloquial and limited" might be considered "perfect native speak" by the ESLs who often don't get that kind of environmental exposure to English.


Does ESL stand for English as a secondary language ?

Is that in common usage ? I have never seen it used to designate a group of people.


> Does ESL stand for English as a secondary language ?

I believe so.

I picked up this usage (ESL as a descriptor of person) from forums and boards around the internet. Not sure how correct it is.


It is accurate and also still in use in academia. In every educational institution I have worked, "ESL" is used both verbally and in digital records.


It's been in use for a long time. I remember seeing it in the 70's in colleges that taught immigrants English for free in night classes.


> Most people who are smart learn that emphasizing that you are smarter than others leads people to hate you and it generally makes one's life more difficult. How did Wolfram not realize this?

That also speaks tons about people who take offence at (hate) others for giving themselves generous credit.

Maybe, but if someone was really beautiful and they had to keep pointing this out to you, would you like to hang around them? Or would you think they are vain and self-centered and basically avoid them because they fit the definition of "obnoxious."


I usually roll my eyes or have a chuckle (if they are particularly funny) and move on :)


> I cut back on fried foods

That's the only 100% banned item in my diet because fried stuff makes my skin look ashen and ugly. Whenever fried foods come up in conversations everyone immediately assumes I am talking about fats vs carbs and proteins. Google does too. I can eat most any fats, even butter sticks, no problem. I was wondering if anyone knows why fried foods are so bad.


It sounds like you might just be allergic to certain types of oil. No need for wooey explanations.

Also but not likely to be the reason for your symptoms - cooking with vegetable oils releases toxic chemicals linked to cancer and other diseases,


I used to do squats exclusively. Nothing but squats until my body simply stopped responding. Then I switched to deadlifts. Nothing but deadlifts. Initially everything was fine until my body stopped responding to deads as well. Kettlebells might be just what I need. Thanks.

Mathematical Foundations of Computing by Keith Schwarz:

Just saw this via another recent HN thread and started reading it. The writing and exposition of topics seems good to me.


I checked it out and it seems approachable. Is there any resource that provides answers to the problem sets ?


I am not sure to be honest, but if you want a book with answers, try Discrete Mathematics with Applications by Epp [0]

It has a very large number of answers in the back, but not all of them. You'll come out ahead even if you only do the problems with an answer as each section has anywhere between 30 to 60 problems. If you want to try every problem (or some of the interesting ones that don't have answers), there's an instructor's manual for 3rd edition. The one I linked is the 4th ed. No problem as the editions 3 and 4 mainly differ in numbering of their sections and chapters, so if you match a chapter from 4 ed to the one in the instructor's manual for 3rd ed, the answers are identical and in the same order. If none of this works for you, either just google the problem or visit MSE [1] as almost none of the problems in the undergrad books are original and many people before you have asked the same questions many times over.

Note, the price of the book is steep, but I am sure you know of libg3n.

Great! Thanks.
