From my reading of the article, a lot of the performance improvements come getting rid of the mutex in front of their hash based metadata cache by using a lock free hashing algo. These changes originally came from Oracle's MySQL 5.7 wo

That was my thought as well, but this change was done by an Operator and not a DBA, who tend to be a bit more curious about these kinds of changes.

I've answered this question once before, and this is what I wrote. MySQL is battle tested and operationally sane to manage at scale; I'm talking specifically about replication. I've been a DBA for thousands of MySQL hosts in

That may be why MySQL is popular for small installations, but that's not why it's popular with companies like Facebook, Google, Twitter, and Pinterest who run replicated clusters that number in the thousands. It's popular at

I've lived in Seattle since the late 80s when I got the hell out of Olympia WA where I grew up. I remember when it was nearly impossible to find a decent tech job in the city, and you had to cross a bridge to Bellevue or Redmond, which

By that logic malware presumably couldn't modify them either, right?

I think GarageBand also ships with the OS (or at least it used to) so I wouldn't be surprised if it's also on the "system owned" list. This pushes all my security vs. liberty buttons.

Thanks for bringing this up, I just cancelled my download. There is no way I'm going to run an OS that attempts to limit my power to delete or modify applications. I think this may be the final straw for me and OSX. I very recently had

Yeah, the magic behind the Monkees were Tommy Boyce and Bobby Hart, who wrote most of their hits and later toured with Dolenz and Jones.

Ms. Murphy's bio page describes her as a "guerilla marketing expert", and perhaps that is what this is. If leveling ridiculous accusations at your critics using obviously fake Twitter accounts is "guerilla marketing&quot

I disliked this article as well. Saying 'Ctrl-f' instead of 'search' irks me, it's unprofessional, and furthermore we all know Ctrl-f is forward-char.

This was an excellent read, and had the technical meat I was looking for. Too much actually, my eyes started glazing over during the CAN protocol checksum part. It was a hair-raising experience learning that up until recently thousands of c

Haha, I'm pretty sure tweets and DMs have been recently moved out of MySQL, although AFAIK the social graph is still there.

Your friends might roll their eyes at you putting Soylent in your Vessyl and monitoring your daily caloric intake on your Apple Watch either, but nerds want what they want.

Depending on how good the specm is... The article says that besides being small it's also high bandwidth and high resolution. Not sure how many distinct things you can identify based on spectral analysis alone, but I have high hopes

It's not just about how fast you can push code out your brain, but how fast you can manipulate code in your editor. Uppercase that constant, move subroutine bar to file foo, indent this section, move this code block 'til after the

From what little I know about German beverages, it seems like many of them have cool slogans. I used to drink Afri-cola back in the day, and I think the slogan was 'Kein Vergnuegen ohne Gefahr' or roughly 'No pleasure without

A readable 80x24 text mode is the bare minimum for programming IMHO. It's probably detailed enough for that, but it's not going rival your laptop/desktop experience any time soon.

Thanks for pointing this out, I agree it's tacky. Unfortunately this sort of thing seems to be part of nerd culture. I know it's gotten bad when I have a serious urge to sidetrack PostgreSQL threads with MySQL related trolling, bu

My general sense is that MySQL is battle tested and operationally sane to manage at scale; I'm talking specifically about replication. I've been a DBA for thousands of MySQL hosts in production and just a handful of PostgreSQL clu

Fascinating article, thanks for sharing. I'm working hard to try to get my dopamine based desires under control, I hadn't seriously considered meditation as a tool until now.

I remember quite clearly the jump from 300 to 1200 baud and how amazing that was. When 56k modems came out, I thought, that's it, we've reached the limits of what we can push over copper. Joseph Lechleider proved me wrong. I use a

Yes, and you you absolutely have to ship proprietary software that connects to MySQL you can use libdrizzle[0] which is a BSD licensed cleanroom implementation of the client library. Alternately you can go dig up the old original public dom

Thanks for sharing, great article. I think most of the folks singing the praises of Postgres over MySQL have never had to operationally support both databases in complex multi-DC replication environments. The answer to many replication issu

Human bodies can vary when it comes to efficiency of converting food to energy. I do not doubt this, but is there any evidence that these variances are significant? Treating human bodies as 100% efficient food to energy converters is usef

I'm guessing the negative comment was due to a jocks vs. nerds cultural thing, combined with the fact that your advice was well.. bad. I'd argue "the best first step" is not to start pumping iron, but to develop and exec
