The comment was meant to be lighthearted, but on the serious side we both: 1) Probably won't have done the full sort of inspection of our SSL cert checking to really ensure you aren't being MITM'd. 2) We won't have a che

The first two issues (JIT code compilation and integer overflow/underflow) add up to a significant fraction of the crashing bugs in Gecko that have security exposure. I can't provide specific numbers, but both are well over 10% of

Certainly, as njn has brought online each new memory profiling feature, he's discovered something ridiculous we were doing in Servo (e.g., copying things we thought we weren't; continuous memory leaks; poor use of underlying nativ

One fun thing about reimplementing the Web Platform is that you run across all of the spec holes (particularly in much older features, like tables, borders, etc.). Where possible, we're trying to at least determine what current browser

I should mention that I and other hiring managers I've talked with are moving away from posting on the "Who is hiring?" post. It was pretty useful ~6 months ago. But, the amount of spam generated from recruiting and sourcing

Yes, SML/NJ and Manticore (which have more than a bit of overlap) are still the main supporters. The x86_64 backend is only used by Manticore today; SML/NJ is still only 32-bit, though there's some work going on to migrate it

It isn't listed on that somewhat-old page, but as part of the Manticore project we (primarily Mike Rainey) also added an x86_64 backend to MLRISC: https://smlnj-gforge.cs.uchicago.edu/scm/viewvc.php/MLRISC&#x2

Yes, this is mentioned in the paper, right next to where they talk about the correlation. The most telling part, though, is where they take some of the lower-25% from cubicle farm/open office spaces and put them in private office space

This talk and my experiences at Microsoft are why I tend to try to steer our projects at Mozilla Research to partner with external offerings rather than doing too much building of our own. It's hard to imagine a world where we build a

You've probably already thought about this, but you might want to make sure clients understand the legal side of things. We've certainly had some cases at Mozilla where remote workers had to be "reminded" that we could o

It's a hard problem, which the COMPlus team knew when they started out. During the early pre-release period, there was a then-NDA-only project, Project 7, which gave grants to people trying to port both commercial languages like perl a

I work at Mozilla (I believe ~70% remote workers) and certainly see people do things like this all the time, though often on a smaller scale. For example, if they have a conference or meeting in Europe or Asia, they might extend the trip to

If you just count *.rs files, rust and its in-tree libraries are around 400k lines, and Servo and its immediate dependencies are around 310k lines. Caveat: use of 'find' and 'wc' is almost invariably totally misleading :
