To be fair, quite a few engineers at Google did yearn for MySQL and a single instance at that. Not for any of the traits you list°, but because it would have let them no longer worry about HA, replication, request hedging, key hotspots, etc

"This caching, along with aggressive pooling of read requests, allows Zanzibar to issue only 20 million read RPCs per second to Spanner." ("Only") I'm surprised by all the numbers they give out: latency, regions, op

Well, if you were employed before/during the 2014 split, you do have a mix of GOOG/GOOGL. Not that it ever made a difference in practical terms.

It's her. She had a loyal following, second only to the guy that used to email the NYC office menus in 2007.

My hunch: a more invasive one. Think of turning off all machines in a cluster for major power work or to replace the enclosures themselves. Maintenance on a single machine or rack, instead, happens all the time and requires little more sche

It's either that or special rooms at an office that have a different/redundant setup. Remember that this happened on a Sunday, so most engineers dealing with the incident were home or elsewhere, at least initially.

I speculated it was something to do with the SDN, among others: https://news.ycombinator.com/item?id=20078433 It was unlikely to be fiber or a router failing, because there's enough redundancy at all sorts of levels (u

Fiber cut? SDN bug that causes traffic to be misdirected? One or more core routers swallowing or corrupting packets?

I know I'm skinny, so I never tried to lose weight or looked at it as a keto diet per se. I don't think I even knew the term at the time. It was more about replacing carbs with proteins. During the winter, when I eat just the same

I run anywhere from 30 to 70 miles per week and I just couldn't follow a keto diet. I have a hard time even just picturing it. Just the other day I was reading about a recent study showing that low-carb diets affect your running. That

Indeed, this is not a new thing. "For every job, so many men, so many men noone needs." Written in the Thatcher days, inspired by the Depression, still relevant today. These are complicated issues, which are not solved by soundbit

Indexing has been rewritten many times over. Even if you removed all the dependencies on Bigtable and co., I think indexing would be the last to move, for quite practical reasons, due to its sheer size and design. The parent poster picked p

Both times I had surgery, I only remember counting down to maybe 7 while laying down, then waking up somewhere else entirely in a wheelchair, with no idea of how much time had passed in between. I wasn't told about things I might have

This could be reverse engineered. If the Bluetooth connection is encrypted, there might be an additional step involving jailbreaking the iOS device (hard) or setting up some kind of MITM proxy. The rest shouldn't be too complicated. It

It is a loop, but passengers are not allowed on that segment. If you manage to stay on the car, you also get to take a quick peek at an abandoned station.

I loaned one for a few weeks and camera was the most useful feature for me as well. The much maligned camera had a more useful outcome still: it's the first (kind of) public device using Google's computational photography, paving

Yeah, those have been displacing Japan along with China. I mentioned Samsung, but was mostly focusing on Japan as an example of a country whose star can and did dim, as a potential parallel for future China. It has taken longer than the few

Well, before China, it was Japan. They dominated the 80s and a good chunk of the 90s. They still have a lead in markets such as cameras and are fairly competitive for technologies like Flash, which they actually invented. Samsung passed Tos

I'm from that area, in the suburbs of Naples, and left 25 years ago, but my family is still there. Yes, there is a higher incidence of cancer in the region and, most likely, chemicals play a central part in that, but a good chunk of ca

The Google indices are very expensive to create and serve. For one, they use a ton of memory. YouTube has TPMs whose only focus is making storage very cheap.

Have you done any disaster recovery exercises? We've started to play with it, but haven't gone that far yet.

Great to hear. I couldn't get more details from them, but it was something about both rebalancing and data recovery. They picked SwiftStack, which is at least in part open source. Maybe by now you have figured who that company is. My t

I worked on Colossus at Google and Ceph is the closest thing out there. Gregory Farnum gave a great talk about it at the Open Source Summit 2017. I heard from someone at a large company, though, that it's not getting a lot of love from

Usually, time series databases use a variety of tricks to store data using as fewer bits per sample as possible. An OLAP database sounds like a much more generic system that will cover a larger number of use cases, but won't be finely

That's the design of the System/38, AS/400, iSeries and System i. The unique IDs are 128bit pointers or capabilities.
