Ublock Origin (or equivalent) compatibility is a deal-breaker for me.

The reaction here is interesting, but it won't change my opinion without concrete feedback. Please tell me why this opinion is wrong.

Yes, as well as some lower-level software. (sharing portions of a PCI BAR region isn't trivial in a hypervisor, when multiple guests are involved). Mixing safety criticality levels is hard.

This kind of question is a gold mine, IME. When I interview network protocol devs, my favorite question is: "tell me what happens between the time you type something into the address bar and when you see a result". so many opportu

I've got a customer that wants to get access to the PTP[1] registers of a NIC from user space. The customer suggests that context switches introduce too much latency and indeterminism (pre systems integration phase - lots of software

Xilinx has being doing CPU+FPGA for longer than that. I did some C runtime enhancements for the PPC 440 included in the FX70 for a product made by a former employer (shadow stacks for better CFI, more locked down MMU use, etc).

Is any employee of Docker, inc. critical to your use of containers? Is any copyrighted, non-OSS Docker, inc. code critical to your operations? Where does the money go.

>No, those are all policy choices we made. Who is "we"? I doubt it. I certainly don't recall being asked, and I'm in a privileged position, relatively speaking. I'd be curious to see how I could participate in th

How large is large? Hiring junior engineers or developers definitely happens in companies smaller than FB or GOOG. Perhaps you mean something specific by "capable"? I won't disagree that c++ (as a technology) can be a minefie

Do you watch professional sports (football, basketball, etc)? Watching competitive video games (starcraft 2 is my favorite) has a similar appeal, to me. If you don't watch any sports, than the appeal of esports may not make sense to yo

Thanks for the references - I'll look into them, I'm definitely interested in multi-tool workflows given my experience (systems programmers aren't necessarily mathematicians). If only the systems programmer could be pointed a

Yeah, dealing with vendors can be frustrating, for sure. I'm still a little sad about the I-178 eval, since a lot of the work I saw done by RC was quite good, if limited in scope. Seeing The vendor (imo) misrepresent that effort to sel

Regarding the arxiv link on verification methods, I'd be careful reading too much into the summary tables. The authors don't appear to have done their homework there (they overstate the C&A accomplishments of the company I wor

True enough, but so what? Who among us will claim that monetary success is not based on circumstance? Certainly not me.

volume pixel (voxel) is already a term of art. I'm not aware of jargon to decouple the sampling precision in different axis, though that probably exists too.

I disagree that it's undesirable for back-up and restore to be impossible in all cases. Instead, I would argue that plain-text export of private and secret keys is undesirable, as it removes any protections the HSM was supposed to prov

Yes, please. My email is in my profile.

Are you using and/or developing for SGX? I looked into it and got put off by the need to deal with intel for licensing and signing keys, but I'd be curious to know if anyone is doing something interesting with it.

Yes it is. Some variants even include a hardware security module so that you can store your encryption keys on it and keep everything but the bootloader encrypted (assuming proper software support of course).

Indeed. I've got a set for range use and they work great (esp. on outdoor ranges).

There have been quite a few systems that can handle proofs of the kinds of propositions you list above using various different logical frameworks, programming languages, and automatic and/or user-guided proof assistants. That said, it&

Something I've found helpful is pre-heating the board (e.g., with an under-board IR heater) before breaking out the hot air. As another poster has mentioned, chip-quick is also great stuff.

Out of curiosity, how are you planning on handling plating for vias and through-holes? The desire to stop handling chemicals (I have no convenient means of proper disposal) has got me using the on-line prototype services for anything multi-

thanks! (edit) I still don't see any rationale for the theorem prover kernel re-implementation. Again, pointers appreciated.

by jeff_marshall 10y ago
I wonder what the reason for the re-implementation is. Perhaps the existing kernel isn't fast enough at evaluation for training (wild guess)? I'll have to RTFM... (update) their doesn't appear to be any FM. Can anyone post an

Too true - both the negative (who wants to program an abacus), and the positive (there is no magic in this program/device). I feel like developers tend to favor the magic, due to the burden it relieves, without having to consider the n

There is nothing magic about networking! If you are interested, start reading things and playing around. The issue, like most complex subjects, is that most people aren't interested enough in the details to get to the point where they

I can't speak for other aspects of FAA oversight, but my limited experience with DO-178B (A process for certifying software for safety-critical applications) has been mostly positive. While the process is rather heavy (and restrictive,
