Funny contrast to me. I finished getting my kids up into college using my "useful enough to others to be paid for it" software skills and immediately went back to grad school for math precisely because it is such a joyous activity

And the goal of therapy and other treatments is to in fact be fine. Also a common result of child sexual abuse is to feel uniquely specially damaged in a way no one could understand. Cut off from humanity, while in fact the experience is o

That is a useful coping strategy for a child but if you can get away from the abusive family or whatever group, as an adult you absolutely can be free to deal with the effects until you know yourself as a free, powerful, and normal human be

The abusers really can go from threatening a six year old with what sounds like credible threats to making the adults laugh within seconds without any visible whiplash. And the will to deny is extremely strong; to believe the child one has

In the formalization of mathematics, things are built up structurally. Zero is the empty set. Natural numbers are sets that contain smaller natural numbers. Integers are pairs of natural numbers under an equivalence relation (a,b) ~ (c,d) i

Most of the research on child sexual abuse in the US shows that rates have dropped by about 50% since the 1970s. https://www.ncbi.nlm.nih.gov/books/NBK201120/ search for "Evidence for a Decline in Physical an

I was sexually abused by a family member at young age. It certainly affected me in negative ways, and should be stopped, but it is also important to emphasize to current victims that being abused doesn't make you uniquely and shamefull

For a long time I blamed myself for things being difficult. But self knowledge surely includes knowledge of how conditions affect your nervous system. Totally plausible a given nervous system works better with a typewriter than any network

To be radical is to seize the root, but for humanity the root is humanity itself.

I find infinite dimensional spaces even of zero curvature to be a bit creepy. Especially with a vector space structure, that just makes it worse.

My understanding is that QFT is not axiomatized - it works but there's a bit of hand-waving at the level of actual proofs. There are people working on this, but currently physics is physics and maths is maths.

That is also true for creative people. Generating interesting ideas is one thing then filtering out impractical or unaesthetic ideas is also needed.

I would and sort of still do buy the text books as soon as I registered and make sure to read at least the first few chapters before class. Makes it easier to know what to take. It’s on, ask better questions, and remember it longer. I would

That said, they are surprisingly useful. Once I get the understanding thru whatever means, I can converse with it and solidify the understanding nicely. And to be honest people are likely to toss in extra \sqrt{2} and change signs randomly.

In my last homework the professor omitted a required assumption and I nevertheless proved the false assertion. Extremely embarrassing. This happened earlier in the semester and I correctly failed to finish the homework problem. I am getting

True tho detecting untrue maths is a key skill. Unlike software there is no compiler tests whatever step to filter out your own minds flagrant errors.

CGI. But once you loose control of your memory in a large code base it is practically impossible to regain it. So you can’t move to long lived server processes when you decide to enter the more modern era.

I find these bugs to be a sign that the app is not using a good wrapper but just mostly gets lucky that the packet isn’t split randomly on the way.

Your time from commit to live is proportional to your rollback to a known good state. Maybe to a power of the rollback time.

I thought this was going to be a python thing that exploited functions returning functions with their lexical scope. I find too many syntactical macros tends to encourage excessively dense code. Tho I usually use packer and terraform to con
