That search doesn't handle head/tail overlaps, but otherwise it's a good approximation. I'm surprised it isn't faster; I think I got a few hundred MB/s on trie-based matching. Protip: bring benchmarks like th

I'm the same way; I found that the creative work that I always envisioned was not happening on the job. Now I'm at home, but I've got emacs open in another window banging out some SIMD code. Maybe I'm ahead of the curve

One theory I have is that the tech community was a lot more nerdy in the past, and we've gradually been diluted out as the tech population has grown. The whole "culture fit" thing just seems creepy to me; I used to work with

There's definitely a need for this, since long-running threads are a huge pain to manage -- connections die, heartbeats fail, etc., and any job that's doing a lot of sleep() loops or waiting for asynchronous notifications should p

Are you internal to a tech org, or is this a third-party service? How much bandwidth do you have with the CRO customer? The reason I ask is that the role may be broader or narrower based on these factors; it may not be perceived as full-on

I've been looking at Apache Arrow ( https://arrow.apache.org/ ) and trying to figure out how to integrate it into the browser. It's an in-memory data format, and the idea is to share the same data chunks amongst va

Well, if you call it Data Science, people will come running to you with their Hadoop skills :). I don't really know the answer, as I've worked with some teams that had strong analytics/CRO penetration, and some that didn&#x27

I have those skills, but let me play the skeptic here and amplify a few questions: 1. What is CRO? (I just looked it up -- conversion rate optimization). Is it spammy? 2. What is tagging? I assume it's instrumenting funnels etc. in

It's possible that moving it off the street has made it so much less visible that these kinds of myths have developed about it much more easily. When hookers were out on the street corner it was a nuisance, but people could see that i

You have 30 days to respond to a data request, so the default GDPR behavior is to delete all data within 30 days. You also mostly want stat-significant aggregations, so if you take care to keep those differentially private (only aggregate l

At one point for phone screens, I just asked people to code up strcmp. I got some amazingly bad answers. Some of this code-screen mistrust seems to come from the flood of poorly-qualified candidates; maybe there's a more diverse pool

It's entirely bullshit, and I regret being on both sides. I used to do coding screens, but I feel like some moderate knowledge of syntax and a decent education is enough to skip the rest. The whole cargo cult of coding screens came u

At times I've added a graphviz output method to a data structure; it's pretty handy, and you don't have to do a separate design diagram.

There seems to be a real push towards homogeneity in teams, and I've seen it lead to bullying of people with different skills. At one point I was working with a guy who had a prototype of a complex clustering algorithm. He did a great

I implemented some of the TOS requirements at Zynga, and we did a lot of TOS vetting with the legal team. I personally nulled out some fields that TOS changes forbade, and AFAIK Zynga never had any interest in sharing or selling the data.

I agree but one nitpick: merging into the bike lane before a right turn is the correct maneuver.

I love Jefferson, but the reality is that half the economy up there is based on destroying the environment, and the other half is based on cleaning it up. Iron Mountain Mine is one of the biggest Superfund sites in the country, and it took

The trauma surgeon who treated the North Korean soldier that escaped through Panmunjom was trained in San Diego, and that makes him one of the most experienced trauma surgeons in the country. There's much less practice available in co

It's my understanding that many people work on the buses, so letting them take food with them doesn't seem like a stretch. The theory behind workbait is exactly this scenario -- that workers give an extra half hour to the company

In my case I was thinking of long strings such as SQL queries. We would show a few initial words, but in SQL they're typically the same. For example: select sum(sales) from tablexyz where region = 'West'

This looks good, but it reminds me of a problem I've noticed in this situation: the truncated cells have virtually no information. Take this example data: 999995 999998 999999 Imagine we have 5 display digits availabl

I've been pondering how to identify the cached line without a timer. It seems like a classical race condition if multiple reads can be issued at once, eg by ILP. Another thread could easily figure out which load completes first.

They seem to have gone from saying "We can't attribute event X solely to climate change, but X is more likely due to climate change" to saying "X is more likely due to climate change".
