Most of California's coastline is sheer cliffs. There are reasons why our cities are where they are.

Every morning, I beg my God to make morons stop replying to me on HN. Today is the first day anyone has promised to make my dream come true. I didn't read those articles in the last 4 minutes because I read them when they were publish

There are literally no server benchmarks anywhere in those articles. Unless you are planning to run a distributed C build node there's nothing in these articles that can inform your choice. Distributed building is an extremely narrow,

Big claim there. On what basis?

Interesting, but it’s hard to see the big utility. Most spam signals are based on behavior and reputation rather that content. Your email can look clean at first, but if a handful of gmail accounts mark it as spam then your whole network wi

It's a mistake to imagine that Google has some kind of centralized "programming languages" organization[1]. The people who designed Angular have probably never even met the people who designed Go, much less been influenced b

You can also get a worse MRI on obsolete equipment at UCSF for $18k. Ask me how I know!

There were NUMA x86 rigs long before the memory controller moved to the CPU. IBM xSeries and serverworks chipsets from around 2000 had NUMA topologies.

These are all embarrassingly parallel multiplication workloads. Would be nice for a change if anyone would run something like MySQL or a gRPC server or something like that, you know one where it actually makes a difference how threads get s

I really can’t more strenuously disagree. At Giant Search writing “subtle” code is very strongly discouraged. The very last thing I want is candidates with a penchant toward subtlety.

It seems like the power consumption of this computer must have been pretty spectacular anyway. 60mW per gate is no joke.

Isn’t it up to the interviewer to ask a useful question? This is exactly how I would find the kth item of a search tree. I don’t feel like that is refusal to engage. Is the question is more like “describe various approaches to the designs o

How snarky do people get on these interviews? If anyone asked me to find the kth-greatest element in a tree I'd write down a loop that increments std:set::crbegin k-many times and then dereferences and returns it. This is literally h

I just looked at my last order, it was a much larger board. I suppose there are different optimal choices for very small boards or larger ones.

GREAT question. For one thing you’re not getting any job in mechanical engineering without a degree and an EIT, so that narrows the possibilities. Companies recruit at universities and this is the main pipeline into the industry. Connection

How do you sort an infinite stream?

Those prices and lead times don't seem very competitive. At Sunstone I pay $5/sq in for 1-day service on a 2-layer board. If I was willing to wait a week it's $1/sq in. I think people who are impressed by 3d printers o

The people profit, not BART itself. BART is infrastructure. Like the fire department, it is not intended for it to be internally profitable. The way the people profit is you put homes in the places that have lots of jobs, mostly so that p

You can get developers to build the infrastructure and finance it on their future taxes. You wouldn't believe the incremental tax from building real buildings in the Bay Area. In one particularly egregious case a single apartment bui

The historical (before 1980) rate of housing starts in American cities was 1 per 100 people per year, not per 100 households.

BART ridership is currently maxed out in the peak direction at peak hour, and carries triple the design number of passengers. They don’t need to expand, they need to profit from the currently underused directions (eg berkeley to Fremont).

Every property within 1/4 mile of the N-Judah streetcar line should have over-the-counter, by-right zoning approval for 7-story buildings with zero parking and no setbacks.

A fun fact is that BART has 48 stations.

The reason Bay Area cities can't afford their water and sewer and roads is because they are not dense enough. Apartment dwellers demand far less water, and drive on roads much less than people who live in detached homes. Density is t

In California, transportation by itself is 41% of GHG emissions and oil production and refining are another 11% so it is a supportable statement that transportation is the majority of this state's CO2 production. https://ww3

I think you have it backwards. We squander the capacity of our main commuter railroad (BART) by surrounding it with dispersed neighborhoods. We need to build dense transit villages around the rail stations we already own.

I’ve never heard of or experienced gcc using some kind of cost model for compilation time, either. With all these huge protobuf-generated files you’d think I would have noticed if it existed.

by thedance 7y ago
The most interesting thing to me is "the compiler reduces its optimizations with increasing compilation effort, when compiling only a single source file." Is this GCC-specific, or does it also hold for clang? And can it be tuned

Thanks for saving us the time. The punch line: Summarize: Slower than std::sort except on random tail. Also a very important tidbit that std::sort is 10x faster than c's qsort for ordered inputs.

Fascists have some great design chops. Check out the propaganda of Switzerland's SVP party. It is :100:.
