Philip is not unique, FB engineering managers of all levels and tenure move into development roles. It's a relatively common occurrence; I'd guess around 5% of managers switch back to coding each year.

I disagree with this approach. My policy as a tech lead (and then manager) was to spread the mundane tasks across the team equally. This let everyone experience the pain points and usually led to faster elimination of technical debt, since

These stories of kids breaking things at work reminded me of ultimate kids-at-work-gone-wrong story when a Russian airline pilot let his kids fly the plane. Such a tragic story. https://en.wikipedia.org/wiki/Aeroflot_Fl

Hmm, that's interesting. We never did 25 and went to 40 and 100. Well, 10 for normal hosts, 40 for top of rack switches and heavy i/o hosts, and 100 and beyond for future TOR and aggregate switches.

Yeah, I didn't realize you couldn't do that. Next time I'll just put a link to the comment versus pasting it verbatim.

Thanks for the reply Brian. I'm a big fan of sharding across hosts and doing your own RS. I'm mildly surprised that you're disk and CPU limited, but there's lots of factors that can come into play with that and it sounds

It's always great to see storage hardware being opened up, thanks Backblaze. I have a question after reading the Vault overview here: https://www.backblaze.com/blog/vault-cloud-storage-architect... I'm curiou

This post makes the case that Apple is not organized in a way to allow it to effectively run services like iCloud, iTunes, Apple Pay, etc. I haven't worked there in ten years, but back then at least, I'd agree with that. Teams and

FreeBSD excels at giving you control over how the OS is packaged and built. The ports and packages system is great and makes it straightforward to compile or install packages, respectively. You can build the entire OS with 'make world&

We generated many candidates beginning with facebook, so I don't recall when that one was found--it just happened to be the one that looked the best. There's a number of backup memorable domains that we kept the keypairs for just

It requires substantially more compute power to match "facebookcorewwwi" vs just finding a hash with a prefix of "facebook" that looks readable. Good luck hashing the remaining eight characters!

Alec Muffet has done a lot of work to get Facebook running on TOR and he's a true believer. I really enjoyed working with him when I was at Facebook. He also did a lot of work to get .onion domains to be recognized by registrars as a s

You've been able to setup a US debit card with your Messenger account and then use that to send friends money, so you can use that payment info with the Messenger platform integrations too. I'm guessing that FB processes the payme

It's harder to land on water but it requires less fuel overall, and is safer. Check out the launch/recovery diagram on this article and it will become more obvious why it would require more fuel to return the booster to land: htt

This isn't really correct. There's four things you have to be aware of when going through a corner--throttle, brake, orientation, and traction. Oftentimes the fastest route through a corner doesn't match the bang-bang approac

It's also used on some rockets and guided bombs, which is where I first heard about it. It leads to rougher trajectories but it's a more reliable control surface since you only need to handle zero or full deflection on a given fin

The best hackers I've worked with didn't have degrees. The best software engineers did. You need both. On the hacker front, I noticed a lot of patterns--they had a lot of drive, were self-taught (obviously), and had other things a

Apparently Hubspot did dirty tricks to try to obtain a copy of the manuscript, as well as blocking publication. The CMO and a VP are gone because of it. You can't make this stuff up. https://www.bostonglobe.com/business

I think you're pretty far off the mark when you say that Oculus is at risk if they don't sell enough devices. Of course, we have to go off of what Oculus and FB says, but they are working to create an ecosystem and market for VR e

The author is talking about publicly viewable emails and chats (e.g. mailing lists, IRC, Slack). I think the surrounding context makes that clear: "When talking about a team that is not producing work fast enough, look at the records.

This patch makes it easier to scale inbound TCP requests across multiple cores on your CPU. This helps with both denial-of-service protection, as well as scaling up if you're doing a lot of raw packet processing (e.g. a Layer 4 load ba

Thanks stan_rogers and splat, using local noon plus a clock makes total sense after you described how it works. And I just read a fun Wikipedia node on the history of longitude for good measure too. https://en.wikipedia.org/

Do you mean latitude? I remember the days being longer in the summer when I lived at higher latitudes, but I'm having trouble seeing how you could calculate longitude by looking at sunrise/sunset.

RIP. Zmodem was so amazing. It was a huge step forward. I got started in 1980 with an old Hayes 300 baud modem on the Source, and graduated to Compuserve and BBSes in 1986 when I got a 2400bps modem. When I got a 9600bps modem in ~1988, tha

You have to encrypt the transport at the application layer when you're talking about the scale of major internet companies--there are so many links going out of each datacenter that it's not feasible to do IPsec or similar lower l

"Posted on October 21, 2011" This is almost four years old, shouldn't it have (2011) in the title? I don't think Facebook even does this anymore.
