I would say for sure LTO tape drives.

You're right and it did get used for that. Unfortunately that's nowhere large enough a use case to support the entire product/business/r&d.

Oh hilarious! The business logic for getting optimal routing for faxes was... quirky. Picking the right source country/line/carrier to get the best quality line while getting the lowest cost and balancing capacity. In the old days

Booking is the largest and thus a juicy target for both attackers and articles. Having worked there, I know that competitors had the same problems though.

Nice catch! That was indeed something we found about a decade ago when I worked there. I don't recall what the security folks tried to do about it. Generally, though, more and more hotels shifted from faxes to API integrations via chan

And even though I've not worked there in many years, I can tell you with extreme certainty that booking doesn't do that. They're also (hopefully obviously!) PCI compliant.

IIRC when I worked at booking until 2017, they had already stopped the practice to share customer data via email for privacy+security reasons years ago.

Back in 2005 the researchers who worked on EUV lensing (mirrors, really) were very cynical and thought that it would never pan out. Coffee breaks were hilarious. It ultimately took a whole lot of time indeed.

My recollection from the Pierre Auger telescopes was 1-2 degrees uncertainty. TA is likely a similar order of magnitude. So matching a single event against candidate sources might not be the most reliable analysis. (Caveat: I didn't di

We've had many more events within an order of magnitude of these events' measured/reconstructed primary energy. The spectrum is a power law. While theoretically something completely different could be happening in the atmosph

Several of them use multiple as-independent-as-possible detection methods. The most common are ground stations in a grid that measure high energy particles passing through, and then correlate them in time, followed by ultra fast (in terms o

To our best understanding, particles of such high energy do not originate in our own galaxy. We don't have a good understanding of what exact process might be putting this much energy into a single particle, but the commonly accepted a

Yes, it's the same Spanner that's used internally. But obviously it's progressed hugely since 2013.

That's nonsense. Booking.com with it's subsidiaries was about 18000 or so people when I left in 2017. About 1800 of that were in engineering The vast majority of staff were working either on the supply or customer service side.

Not with GCS, you don't. https://cloud.google.com/storage/docs/availability-durabilit... Are you thinking of Persistent Disk (PD) and Replicated PD? (I work on storage at Google.)

While we're at sharing neat vim configs, here's the one I was quite happy with at the time: I got tired of indent style arguments. I don't care. So I wrote a little heuristic to detect indent style, then configured vim with m

Since there's a ton of Google employees here - reminder that Google does gift matching for this charity!

Some of us enjoy helping other people. First bit of advice I give to new or would-be managers is to learn indirect gratification. Most common failure mode for new engineering managers IMO is the struggle to feel productive given that impact

For what is worth, I'm a fairly senior manager (a few hundred engineers) and I firmly believe and vocally point out the opposite. I'm sure the kind of self dealing you describe is not unheard of, but it's also pretty cynical

The entire story isn't about laptops. It's about the workstations that may be used to work on code locally (or also build it locally). These machines already aren't allowed outside of premises.

It is the case at Google and none of them are actually air gapped in the real meaning of "air gapped".

Yes, though not exclusively anymore.

There's a reason the profs love Landau/Lifshitz. The books have a certain elegance that, once you have a decent understanding of the subject already, is easy to appreciate. But as a first year theory student, that's just not

You're right. It's not untested at all. It's just not instantaneous, unfortunately. :)

That's correct. Long term holdbacks actually are way way harder to implement and maintain in a fast moving product than meets the eye. We had passionate and ultimately unfruitful conversations about how to do that when I was there in 2

So one thing we did was for (a/b style) experiments to continue to collect data even after taking a decision to enable or disable[1]. No new sessions/devices would be added to the experiment, but those already exposed would still

Ah, that would explain, thank you. No way they would have been able to make that change on hotels.

I worked at booking until late 2017. I was responsible for all their infrastructure and tooling development until the start of that year. We all hated the urgency messaging internally. Hated it. We felt bad. Many of us were reasonably proud
