you can use an expander or something more advanced like Ozone 12's Unlimiter. you still lose signal when you compress even if you're not clipping so it won't be perfect

there's scrollback search in the nightly build if that's an option for you (I've been using it a ton for a few months and haven't seen any bugs so far):

Uberfreight is also doing very poorly. From my understanding the Transplace acquisition was somewhat of a merger/UF trying to get out of only the 3PL business and Uber is just trying to get UF's losses off their books. There are not as many synergies as you might think due to the way freight brokerages and their deals with shippers+carriers work. One reason UF didn't acquire Convoy: it only makes sense for a brokerage to acquire another brokerage if they can get more customers (shippers) from that acquisition. But most customers of UF are also customers of Convoy, and are splitting their loads amongst multiple brokers to diversify risk and commoditize brokerages. So if you're a shipper giving 20% of your business to Convoy and 20% to Uber Freight, you won't turn around and give 40% of your business to UF now that they've acquired Convoy, you'll just go find another broker to give your business to.

I haven’t read any of them, but from what I’ve heard of the plot of the first, it seems reasonable to want a spoiler tag here

Yeah it was pretty well documented that Snap's behavior on Android (literally taking a screenshot of the viewfinder) was way worse than on iOS, and features like e.g. video would always come out on iOS before Android

In suburban Ohio public school, I was taught abstinence-only education in 2013. Could have changed since then though

The problem in college is bad, but the problem is some high schools is even worse. At high schools without block scheduling, every day might be a 6 am alarm to get to school by 7:00.

This is the definition of the gambler's fallacy. However, if you look at a chart of the stock market vs. a chart of a coin being flipped many times, they will look very different. While a coin being flipped will either asymptotically trend towards zero or a positive slope of .5 depending upon how it is charted, the stock market will have large peaks and valleys, meaning that after a period of high growth (overvaluation), the market will not continue to value these stocks at a steady growth of 10% per year. Instead, the market will correct the value of these stocks, which looks like a short term undervaluation and so we should expect "more tails than usual".

New comment by macmccann in "H3: A Hexagonal Hierarchical Geospatial Indexing System"

macmccann — Fri, 12 Jan 2018 19:36:53 +0000

For anyone else wondering, like I did, why you would use a hexagonal indexing system instead of a (roughly square) latitude longitude system, from https://eng.uber.com/elk/:

"Data size matters in Elasticsearch; a large index means too much data, caching churn, and poor response time. When query volumes are large, ELK nodes become overloaded, causing long garbage collection pauses or even system outages.

To address this, we switched to hexagonal queries, dividing our maps into hexagonal cells. Each hexagonal cell has a string ID determined by the hexagon resolution level. A geodistance query can be roughly translated to a ring of hexagon IDs; although a hexagonal ring is not a circular surface, it is close enough for our use case. Due to this adjustment, our system’s query capacity more than tripled."

That's a good suggestion. We'd have to figure out how to authenticate the users first.

That's a good idea! We think that the current product offered by Courses@Brown is finalized however, so we're not sure they would be open to changing the software like that.

Thank you for the feedback! There are plans to expand this project and several other related ideas into a more extensive and usable tool to help Brown students plan their courses over four years.

Hi everyone! This is part of a course project my group did at Brown University attempting to create a better system with which to find Computer Science courses. Part of the project was to post the website on a forum for feedback, so we decided to use Hacker News. Let us know what you think!
