Efficient multiple-stream concatenation in Java


I want to combine the elements of multiple Stream instances into a single Stream. What's the best way to do this? This article compares a few different solutions. Stream.concat(a, b). The JDK provides Stream.concat(a, b) for concatenating two streams. void exampleConcatTwo () {. Stream a = Stream. of ( "one" , "two" ); Stream b = Stream. of ( "three" , "four" ); Stream out = Stream. concat ( a , b ); out. forEach ( System. out :: println ); // Output: // one. // two. // three. // four. }.

A friend recently told me a story that had nothing to do with business, but unintentionally had a great lesson for all of us. He had asked his arborist if he could move a mature tree from one part of his property to another – to make room for an addition to his home. “Yes,” Yes,” replied the professional. “And how much would it cost?” To which the arborist responded, “We’d charge $18,000 for that.”.

Snapchat will make Los Angeles a stronger tech hub

TechCrunch LA

If you were to write a history of Silicon Valley, you could do it by looking at a series of major diaspora. Companies like Google, Yahoo, Oracle and PayPal attract top talent for years; when they reach maturity or a major liquidity event, their talent disperses and germinates into the next generation of companies. It’s quite possible that Snapchat could do the same for L.A. Read More. Column Social TC Los Angeles Snapchat PayPal Mafia Evan Spiegel

Confessions Of A VC: Crap – Why I Passed On Uber’s Seed Round


A version of this article previously appeared on Entrepreneur.com. Did I passed on Uber’s seed round? It’s worse than that. I never even bothered to listen to Travis’ pitch, even though I was repeatedly offered the opportunity. I then passed on Uber’s A Round as well, which I thought was valued too high, in light of the company’s progress. Too bad, as the initial funding round has increased over 4,000 times in value, making a $250,000 investment worth more than $1,100,000,000.

Think about Performance Before Building a Web Application


“It was running fine.” ” In our performance consulting work, we often hear variations of the following: “Our web application was running fine with a few hundred users. Now when we run a promotion with our new partner and get a thousand users coming in at one time, it grinds to a halt.”.

The number one advice I give is “stop trying to be too smart”.

Los Angeles is a transportation tech powerhouse

Mangling JSON numbers


If we have a long (64-bit integer) that we serialize into JSON, we might be in trouble if JavaScript consumes that JSON. JavaScript has the equivalent of double (64-bit floating point) for its numbers, and double cannot represent the same set of numbers as long. If we are not careful, our long is mangled in transit. Consider 2 53 + 1. We can store that number in a long but not a double.
