In my case, funnily enough, I find public speaking much more enjoyable than attending, say, a wedding. I guess this is very multi-dimensional thing...

This gives me an idea. Next time I'm going to see how much drainage I experience when I'm socializing with people I don't mind offending!

Would you say introversion and social anxiety are two distinct phenomena? I always viewed these as existing on the same spectrum.

I've noticed the same. I think self-confidence grows with age and we become more and more comfortable in our own skin. But then at some point (perhaps in our fifties) we pass a threshold and enter the witty curmudgeon territory. Edit:

For over 25 years I wondered why social events drained me and what neurological phenomenon the metaphor "energy" stood for (which this article and many others like it don't seem to bother investigating). I've recently co

Yes, it was C++. I was unfamiliar with the acronym "UB" so did a Google search. Does it mean "Undefined Behavior"? If I remember correctly, primitive types other than strings are memcpy'd. GetStr basically returned

Despotism tends to be more efficient than representative democracy at decision making. Representative democracy tends to be more efficient than direct democracy at the same. Effectiveness is another matter.

It was a proprietary messaging middleware library. We actually found even FAST FIX slow.

This is exactly right. It was almost always deltas in favor of snapshots. One of the downsides was that sometimes, debugging an issue required replaying the entire market up to the point of the crash/bug.

Pretty basic. The receiving process usually has an input thread that just puts the messages into a queue. Then a processing thread processes (maybe logic, maybe disk writes, maybe send) the messages and queues up periodic batch acks to the

Actually, even FAST was too slow for us. This was a proprietary messaging middleware library. And this particular market data feed was the direct one into the matching engine itself. For the rest of the system, we used a sort of reliable mu

Political rot is inevitable. Small political units (e.g. committees, HOAs) rot into pettiness. Large political units rot into despotism. I would take pettiness as the lesser evil. Also, the human brain was never designed to handle social gr

In our system, if the message didn't unpack properly, the application would send a retransmit request with that message's sequence number. But in practice, this scenario never occurred because TCP already did this for us.

Despite all the algorithms we employed, the concept of a manual trade never went away. Also, when the front-end was taken out of the equation, the latencies were in the microsecond range. 50ms would be excruciatingly slow for an algorithm.

That just reminded me of the most mysterious scaling issue I ever faced. We had a message to disseminate market data for multiple markets (e.g. IBM: 100/100.12 @ NYSE, 101/102 @ NASDAQ etc.). The system performed admirably under l

This reminded me of a tight-packed binary format we used in the trading systems domain almost 20 years ago. Instead of including metadata/field names in each message, it had a central message dictionary that every client/server wo

I think part of the problem is the concept of an "application", which is a prepackaged collection of functionalities. The user has to start the application to use a function. If software was developed as standalone functions that

Typescript doesn't necessarily make your code any more stable than equivalent vanilla JavaScript that validates function arguments properly. However, it does make the code more terse and the types more apparent. It adds some build time

What we need to counter this insane trend toward unnecessary graphical representations, is to double down on a plain-text knowledge graph version of the Internet. Something that is completely devoid of formatting, with only semantic markup

This is incredible! Breadth, depth and no crap formatting. I can't believe that this isn't more well known.

Feels like something that should be handled at the client, rather than having even more personal info sent to servers. Perhaps something like a face-id that automatically switches the entire device a kids' profile.

I was also put off by the author not being able to make the distinction between a library and a framework. The two are almost the inverse of each other: a framework is an application scaffolding while libraries are the building blocks that

The current enthusiasm around React seems somewhat reminiscent of jQuery about 15 years back. It was the first library to solve a problem that plagued the entire industry. It was widely adopted and considered almost a "standard",
