Also, totally unrelated Twitter story (because I am nostalgic lately and you reminded me of it) Early in my time there we had a major, unexpected load spike in the middle of the day. People where tweeting like crazy, breaking records for vo

I think what your describing was actually a problem that I introduced in our bind configuration back when we used DNS for service discovery. Its not exactly what your describing but I can totally see how it would appear that way externally.

Yea.. "auto increment" in mysql. it SUCKED in so many ways, primary of which was that it required a single mysql database to be the primary for all tweet writes. Every tweet just incremented a counter by 1. As we scaled up that

I am pretty sure that snowflake didn't use a mod of a signed int32. It used a service discovery pool as part of finagle (and prior to that dns iirc). The server used a very simple method internally to convert time into a integer (that

There are some problems that are just easier to offboard, even for huge companies. Very few companies at any level run their own email, LDAP, even HR packages these days. That's all SaaS now. But there are other problems that are just

To be fair I am right there with you, I was just pointing out how nifty they can be conceptually. How is this for a real world example, that wifi interface that you configured via the GUI and clicked "do not share with other users&quot

Perhaps, but his title, and vast over simplification of the technologies he is trying to demystify is doing it all a huge disservice. Its like saying that a "Nuclear Reactor is just a steam turbine with marketing". Chroot was a ve

^-- this! Also, a container can house a container.. kind of. If you think of containers like file system inodes then there is a logical view of containers container1: (init -> dockerd) -> container2: (init -> dockerd) -> contain

Sure, but his explanation of that point is vastly over simplifying what is happening. `Containers are chroot with a Marketing Budget` implies that they are basically the same when in fact the technology behind containers more or less comple

by liquidgecka 4y ago
Uhh.. No. "Containers" are a mix of two major pieces of technology. One is cgroups, the other is namespaces. Chroot is analogous (kind of) to mount namespaces is all. Containers need not use all of the features of all the cgroups

Wow! It dawned on me that you have been working on problems in this space for ten years now! It's amazing to see how far this has come. I still remember the days of proxying memcache and kernel modules to increase file descriptor limit

Okay, something I can speak too! (Though I left in 2009 but it's close enough) I was a SRE on Gmail, and I can assure you that the experience for devs was not great intentionally. We had a pool of dedicated machines that ran various ve

I heard about this ages ago as a concept and I thought it was being made but I never saw it come out. 'Witch Hunter' the MMO based on the world of 'Witch Hunter Robin'. Basically there are two classes. One are hunters. T

It's more nuanced than that. Gore wanted some select counties recounted, bush wanted no counties recounted, but if there was going to be a rexound then bush wanted the whole state recounted. In the end the SCbrules that the 14th amendm

I created and removed several single letter emails as part of a test once, and I made several short names (mine, spam@, etc). The biggest problem was that too short would take the backend down because it received more mail than could be ind

Ohh yea I forgot that I got mailed a bunch of movie pass financial details while they were still a hot property! That was.. erm.. eye opening.

nono.. its a single word that is common as a first and last name. There are a BUNCH of cases where its applicable! =) But yea, 5 characters. I was an early gmail SRE so I was able to circumvent the restrictions. =)

See my comment above.. It is, I was a Gmail SRE that could circumvent the restrictions on that. =)

I was an early Gmail SRE so I was able to circumvent the restrictions. It was a bad idea it turns out. For a project I also created "spam@gmail.com" and caused a production outage due to the volume of mail it got forwarded. =) But

Annoyingly that is different, everything after the + is _ignored_ so only one person can have <first>+<any lastname>@gmail.com. Other people I am guessing use first.lastname and that is where the confusion is. =)

Been there. I posted about this before but I own a 5 character common first and last name @gmail.com address. I get misdirected emails _constantly_. Usually I am polite about it and let people know, but sometimes I make a game of it. I was

1 is not even close to true. I was a Gmail SRE at the time. Sends did not take 5 seconds at the time, they were handed off to the MTA right away. The MTA had the ability to delay delivery due to other projects and Gmail decided to use that
