So RISC-V continues to be nonsense. I mention this because of the latest story about RISC-V continues to demonstrate nonsense.
anandtech.com/show/15036/sif…
RISC-V promises to be an open-source CPU, in which anybody can create a CPU without having to pay licensing fees to a company like ARM. SiFive is a RISC-V vendor with it's own designs that charges licensing fees like ARM. See the problem?
Why would you pay licensing fees to SiFive for a RISC-V design that doesn't work when you can pay licensing fees to ARM for a design that does work?
In any case, MIPS and PowerPC have open designs that you can use that likewise have no licensing fees. Why would you go with something expensive like RISC-V when you can instead just use MIPS?
RISV-V isn't a real thing until you can buy a cheap computer for $40 based on RISC-V running Linux/BSD. Until then, it's just vaporware. I'll bet that doesn't happen for at least 5 years.

So today I learned of a feature in 'masscan', the '--wait' parameter that controls how long to wait for a response, as explained in this blogpost:
isc.sans.edu/forums/diary/B…
Now you might be asking yourself, that as the author of masscan, and the person who implemented that feature, shouldn't I already know about it? Yes, you'd think, but masscan has so many features I've forgotten half of them.
Anyway, when scanning for RDP, monero miners take up 100% CPU so it takes them longer to respond, so you need a longer wait.

No, we aren't doomed. That's not how hacking works.

Hackers don't cause one big "doom", but a small background noise of constant small problems -- problems that get fixed. It's that way with the Internet, it'll be that way for self-driving cars.
Sure, some jerk is will discover how to scan the Sprint network and cause all the Jeeps in the area to halt with a single command, potentially killing a lot of people. But that jerk will almost certainly be a researcher who gets the bug fixed rather than a murdering hacker.
The potential sounds bad, but frankly, doing this is about as hard to carry out as a sarin attack on a sports stadium. If you wanted to cause "doom", there's actually lots of other ways you can already do it. People don't now, and won't in the future.

This story (from news.ycombinator.com) is a great example of tracking down "impossible" bugs in code. I mention this because it's the sort of debugging effort they never tell you about in school.
marcan.st/2017/12/debugg…
As a programmer, you'll eventually encounter a bug that's "impossible", that you can't figure out no matter what you do. It's a wall that you hit, and it's very demotivating. Programming school doesn't warn you that this will happen, or teach you how to cope with it.
Big engineering organizations are have two groups of programmers, those that get stumped by bugs who must ask others to help them figure out what's wrong, and programmers skilled at figuring out bugs, helping other people out.

Last week, the executive producer of Ellen, Andy Lassner, and CNN’s Jake Tapper used their collective reach to take 30 seconds of a 1.5 hr interview I did out of context in order to smear me and grossly misinform as many people as possible... (THREAD)
My instinct was to ignore it... cause frankly, I don’t care about people like them; entitled elites, clinging to the bones of a dying world. Anyone who’s been paying attention AT ALL over the last couple of years knows guys like @andylassner and @jaketapper are not the future...
The future belongs to those who refuse to sell their soul, those who refuse to feed the eye, those thinking original thoughts, asking questions, researching, speaking the truth, and encouraging others to do the same. Those who aren’t merely foreground shills for something else.

Kubernetes Borg/Omega history topic 10: In honor of #KubeConEU and the 5th anniversary of open-sourcing Kubernetes, I’ll add more perspective from the Borg and Omega teams to the origin story
Internally, Google puts a lot of emphasis on both resource efficiency and engineering efficiency. For both reasons, back in June 2013, a few months before GCE was ready to GA (cloudplatform.googleblog.com/2013/12/google…), the Borg and GCE teams started to work more closely to improve both
The initial focus gravitated towards directly supporting features needed by Cloud in Borg so that Cloud wouldn't need to work around the the lack of those features (see my previous comment on 2-level scheduling: )

1/n GameDev Environment II: One weird trick to get a 70% performance boost on your 2990WX #threadripper and other windows settings to change

A Yak Shaving for Fun & Profit series™
2/n TLDR: Setting your CPU affinity off of Core 0/1 sometimes gets you a big perf boost. Windows scheduler was not designed with high NUMA core counts in mind
You can use powershell scripts (Start /affinity [mask] “” [executable]) or if you're like me, use ProcessLasso
3/n Details:
Was seeing some very terrible performance behavior on TR2 where it was worse than TR1 or other small core count CPUs.
After investigating on the net, turns out there's lots of contention on Core 0/1 with Windows
