Congrats on some insight into Rudin! He got less terse over time. His Real and Complex Analysis is terrific -- hardly terse at all. The only question I had was, why regular Borel measures? Sure, if I went back and studied again where

For my using OP in my post, well, here on Hacker News (HN), that is a standard abbreviation. But, yes, good technical writing would not do that without, say, original post (OP) or some such. > There was a hyperlink Sorry, clearly tha

The issue here is not me but some bad technical writing. The OP failed to explain that a prerequisite to reading the post was being a long time AWS user. Then, the OP was bad technical writing. Done. QED. Without such a warning about pr

I'm just saying that there is bad technical writing, that there's no good reason for it, and that it's darned costly. If the that OP blog post was just for existing, old AWS customers, then find, good, okay, sure, of course,

Thanks. They would have been doing better for their business if they had made that point clear. Again, my gripe is, better writing is needed. Why? The writing now too often results in absurdly high costs for absurdly poor reasons. The cos

How much is like turn key and how much is lots of one off, proprietary engineering and system integration ? I was guessing that maybe for the fabs themselves, mostly there was some one company that delivered fabs. Or, why reinvent the

I strongly disagree: I'm under no obligation to have followed AWS for the past nine years. Instead, in each field, we should write in ways as self contained, and make the minimum assumptions, possible. In particular, in technical

Okay, at Google I found that IAM abbreviates Amazon's Identity and Access Management . So, the OP has an undefined three letter acronym. Suspicions confirmed: The OP is an example of poor technical writing. Why do I care? I could b

As I recall, there is microelectronics fab work in Taiwan, South Korea, and, in the US, at IBM and Intel, at least. And maybe China and Russia are trying to get caught up in fabs. I wonder: What organization, really, is mostly responsible

by graycat 11y ago
Yup! IMHO it has been, since the 1950s, mostly this "sprinting" that was in practice just too difficult, that is, too costly in time and money, for far too large a fraction of organizations, budgets, managers, etc. that could h

Yes. I was not clear: My impression of the OP is that most of the users or intended users will need good documentation on both the applied math and the APIs, details of input files, etc. My post was to say that for the applied math part

I was responding to "MANPADS", etc. Such a device will need detectors of some kind, e.g., heat, radar, and the usual approaches to stealth should help. For close air support, maybe the US wants to use fast, stealth aircraft fi
