You are surprised by vitriol toward young women on Reddit? You must be new.

EDGAR's own search facilities are fairly poor. I mirror and index it in Lucene for my own purposes.

S-1/A are extremely common. I can't recall an IPO without one. There were 8 of them filed today alone. https://www.sec.gov/cgi-bin/browse-edgar?company=&CIK=&type=...

I don’t know about “none”. Updating the age of the compiled representation of a function on every function entrance doesn’t strike me as cost-free. At a minimum that’s a store.

In what way can “STL” be considered a performance hit? It looks like you just threw out every C++-related word you know.

Most jurisdictions in the Bay Area don’t have rent control. Nothing about tenure protects tenants from inflation.

The median 2br rent in SF stood at $4,630 earlier this year. $4k is the all-in price for a $550k mortgage + property taxes + insurance if you buy a house. Of course, you can't buy a house at that price. If literally nobody you know p

If you are renting you can expect to save exactly nothing because landlords simply raise rents to whatever level the market will bear. OTOH if you can control your housing cost inflation then you might be able to save. Note also that "

Just pegging to my own personal experience, the L4, L5, and L6 total comp amounts on levels.fyi are pretty low. I guess it is because they are blended from many different sites. Looking at just the ones from SF, MV, and Sunnyvale they are

Seems cool. But a lot of the things this blog gets excited over are better understood as features of Google’s platform that are available to and exploited by many of their systems. Eg disaggregated storage with append-only immutable files i

No, that's 25 per HOUR vs 350 per MINUTE.

There are 2 DC fast chargers in the city of Berkeley, California. That's at best a total of about 400 miles per hour of charging, for a city of 120k people. EV boosters radically overestimate the widespread-ness of charging infrastru

It take roughly 100 times longer to charge a car than to refill from a fuel pump so chargers need to be WAY more popular than gas stations. The “obvious way to handle this” is to build cities without cars at all, where people walk and bike

There were always computer-dispatched car services in New York, decades before Uber. The reason people prefer Uber is because Computer Car costs $60 to go to the airport and Uber, by contracting with desperate amateurs and their unmaintaine

It’s up to each individual to make the most of an environment where the utterances of senior engineers are just advice. You don’t need their permission.

Python just doesn’t scale. Th language isn’t typed enough to be safe in a large program. Eventually you will iterate over a string or access an attribute of None. And the runtime is too slow. SRE at Google years ago banned new projects in p

The most important thing I learned there was that you hire and promote people not so management can tell them what to do, but so they can tell management what to do. I didn’t even realize it at the time but the first post-Google job I had t

Sort of. I didn’t mention it because level doesn’t really limit your scope. If you have a way to make a big impact nobody is going to tell you to not do it because you’re too junior. It’s just that the higher levels are expected to operate

Really? One thing I learned at Google is that even having Guido on staff can’t make Python work.

At Google there’s an IC ladder from level 3 (new grads) to 11 (Jeff and Sanjay). Basically it’s a pay scale. Half of engineers are below 5, and 90% are below 6. Edit: pretty sure I was off by one originally. But you get the idea: it’s a tri

Absolutely disagree, to the maximum possible extent. My entire job at Google was to find and fix inefficiency in other people’s projects. I didn’t own any projects! But I submitted changes to foreign code daily and I rarely got any kind of

The problem is that this agency is not exactly a move-fast/break-things agile organization. They probably put out the call for bids for this junk five years ago, which means whatever is wrong with it today will be with us for five yea

If a donor is on your institution’s fundraising blacklist and you covertly conspire to raise money from that person anyway it is clear that you are at a minimum tainted by association with that person.

There are tools for that stuff. You can run the unit tests a million times and count the failures for starters. You can also run tests under TSAN which often just points out races. You can also inject clocks or other dependencies and simply

Sorry. I was responding mostly for this audience to the section about handling pushback. One common form of pushback I experienced was from authors who wanted an exception on performance grounds. These people were almost universally mislead

If you did that to code in Google search you’d be required to run a special load test to prove you didn’t screw it up. Nobody should assume either of the things you just implied were obvious. In fact linear search is guaranteed to beat bina

They have a lot of tests :-) Abseil-cpp alone has 2400 tests, at least in the open-source tree. https://github.com/abseil/abseil-cpp/tree/master/absl/base

You can draw bright lines about some of these things. If a change claims to fix some bug, a test must demonstrate that. If I patch just the test into HEAD and run it, it should fail. If this is not the case then the change "needs more
