I am 62, and have been exercising pretty regularly for 18 years. I hate it. At its worst, it is painful and unpleasant. At its best, it is boring. I am fortunate to be able to eat anything I want and not gain weight (even when I don't

You have a point. However, it would be very easy to distinguish between this scenario, and a sale of the company. VCs don't make this distinction. They could.

How often does something like this happen? I don't have statistics, but I believe the more common scenario is that the company gets acquired, and the return on investment is not the 10x or 1000x or 1000000x the VCs hoped for, so they r

I worked at software startups in the Boston area from 1988 through 2013, so perhaps my comments are not relevant to this day and age. But what I read in that note sounded awfully familiar. In the mid 90s, Microsoft was buying up talent left

JetBrains is completely awesome, in all ways. - The best IDEs by far. There is nothing remotely close. I have been a dedicated Emacs user for over 30 years. But there is so much Intellij does that just isn't available in Emacs, that I

I don't think this is correct (about mostly range queries). Scan the code base of any application, and I predict you will see 90%+ queries not involving an inequality. That is for OLTP. For analytics, the answer might be different.

A b-tree grows and shrinks gracefully because each update modifies O(log n) pages. And the base of the logarithm is pretty big. A typical hash table is not graceful in this way, because while each insert is O(1), you occasionally need to re

They can. See linear hashing and extensible hashing.

No. This discussion is about algorithmic complexity, typically counting comparisons. And of course, it ignores constants. If we're counting page accesses, we care very much about the constants. And furthermore, a "multi-level hash

I think this article misses two points more important than anything else mentioned. 1) B-trees are dynamic while hash tables are not. A B-tree grows gracefully across orders of magnitude, and shrinks just as easily. Most hash tables do not

At this point, the only thing I use it for is to get tour dates of a few bands.

OK, so a better keyboard mechanism. But have they restored the missing row of keys?

I worked at Datasaab, in New York, in 1977. We were building a system for tellers to use in interacting with customers. I don't remember the computer model names, but I do remember the language -- DIL 16. It was a weird language that l

What is your point? That database constraints cannot catch all errors, so don’t even bother with the ones they can catch?
558.
by geophile 7y ago
Wow. No discussion at all regarding the correctness of their databases. Is all the data correct, or are there FKs referencing missing PKs? Actually, even discovering this would be difficult, since any FK violation could be just viewing the

Juicero adds another function to the discussion: marketing. Juicero was an example -- a very comical example -- of marketing over everything else: technology and bean counting. Yes, a balance among all three functions is necessary. However,

Thanks. I'll check in with next year's model. MBP is still dead to me.

A scissor keyboard fixes half of their keyboard problem. Next question: will the new MBP be available without the touchbar and with a conventional row of Esc and Fn keys?

I agree. But the discussion is about where AI is heading. And AI undeniably solves some scaling problems. For example, voice recognition for iPhones could have been done by a large horde of people. But AI does a really good job of it now. A

I don't think the problem is super-intelligent AI that we can't turn off (because they are so intelligent that they block our efforts). There is a more insidious problem that is closer: Merely intelligent AI that we don't

No, you don't end up re-implementing your own, you end up implementing 10% of one. The 10% you need. Maybe it maps rows to objects, but doesn't handle object identity right, because that's not what you need. The ideal for me

Here is a much less exalted answer than those in the quora discussion. I am 62. I programmed my first real computer in high school, a PDP-8 with 12k 12-bit words. I didn't explore assembler language, but spent a lot of time programming
