Please don't. It's so easy to blind somebody with a laser. I always get anxious near laser shows, especially when there's a change it's not done properly as it could still blind you several hundred meters away.
That's very much not safe! I was at a resort in Eastern Europe over Christmas and on the other side of a lake someone had a rig like that. It caused me no end of trouble because it kept sweeping across the place where I was seated and this was easily a 100 meters or more. Make sure you know what/who you are pointing at.
> according to a report compiled by a law firm investigating the incident. The law firm, Quinn Emanuel Urquhart & Sullivan, was hired by Cruise to determine whether its executives misled regulators
This is why lawyers are so expensive. Totally worth the money in this case to hire an "independent" auditor.
Especially this quote from the ”Summary of Principal Findings and Conclusions”: “The reasons for Cruise’s failings in this instance are numerous: poor leadership, mistakes in judgment, lack of coordination, an “us versus them” mentality with regulators, and a fundamental misapprehension of Cruise’s obligations of accountability and transparency to the government and the public. Cruise must take decisive steps to address these issues in order to restore trust and credibility.”
The unstated allegation is that they weren't hired for a warm endorsement, but to assuage the regulator and the public.
If that were true, you could expect certain things, such as casting blame towards folks who have left for company culture, or framing issues with informing the regulator as technical difficulties (eg, instead of deliberate malfeasance).
That the resulting report aligns with such expectations isn't proof - but it might raise an eyebrow here or there.
> But in the Sweeden the opposite, optimize for heat.
Not that much. As you mentioned just above, shutters are a layer of insulation. In Sweden, they have big glass windows and no shutters. The purpose is clearly to get the tiny bit of daylight in winter for health sake, but in terms of insulation, it would be better to have shutters, and smaller windows.
CPUs target low latency (they switch often).
GPUs target high troughput (they switch rarely, only when needed).
High troughput algorithms dont have problem with a lot of threads.
Low latency algorithms have problem with a lot of threads (they need lot of cache memory because of constant switching).
> However, a replacement for the traditional HT is likely to come in the form of Rentable Units, a more efficient pseudo-multi-threaded solution that splits the first thread of incoming instructions into two partitions, assigning them to different cores based on complexity. Rentable Units will use timers and counters to measure P/E core utilization and send parts of the thread to each core for processing.
I'm a novice but doesn't this bring back the spectre (ha) of process (or cache?) security concerns that have cropped up with multithreaded approaches in the past years?
I'm not sure "bring back" is the right way to put it: it's been haunting us this whole time.
Getting rid of SMT gives you guarantees that certain resources are separated between software threads. That probably makes it easier for them to focus on making sure that other resources can be shared correctly.
Yeah sorry I didn't mean "bring back" in that its a solved problem, only that I've heard of moving away from SMT (as Intel may be doing here) as one of the best, if hardline, solutions for, at least, some of those concerns. But then the approach the GP quoted seems to step back towards that?
I've been thinking about using them for Christmas lights.
