Here’s a really fascinating animation and analysis of traffic flows with different intersection methodologies. More interesting is that they were done with off-the-shelf steam games/tools found on Steam. I think
Network Extensions 2
Traffic Manager: President Edition
Some interesting observations:
- 4 way intersections with lights (235 cars/min) is only slightly better than a no light free-for-all (191 car/min)
- Standard roundabouts with stops are really horrible, but get pretty interesting and good with a few simple improvements
- There’s a lot of interesting junction/interchange types I’ve never seen before
Appears the pressure is being recognized by Facebook? Facebook said it’s making major changes to shift users’ news feeds back toward posts from friends and family and away from businesses and media outlets
“By making these changes, I expect the time people spend on Facebook and some measures of engagement will go down,” Zuckerberg wrote. “But I also expect the time you do spend on Facebook will be more valuable. And if we do the right thing, I believe that will be good for our community and our business over the long term too.”
nVidia had some great reveals during CES this year. New mobile GPU’s for super-thin laptops, new Xavier SOC for autonomous driving, and major AI/machine learning platforms.
Definitely worth a watch
Babycastles is a New York nonprofit that is a mish-mash of Maker, Indie developer, and art communities. They create interesting and unique art/gaming installations – such as this Pacman version that runs on all 5 surfaces of a room. Check out their other strange and quirky projects.
Videos of more social media site creators and executives speaking out directly against what they created. They call for each person to awaken to how they can ‘program’ you and that each person should make a conscious effort to limit their use of them. Here’s what Chamath Palihapitiya, former Facebook VP, has to say now:
“People need to hard break from these tools. The short-term dopamine driven feedback loops we have created are destroying how society works. No civil discourse, no cooperation, misinformation, mistrust. Bad actors can now manipulate large swaths of people to do anything they want. … You do not realize it, but you are now being programmed.”
Here’s from Sean Parker, former Facebook President:
“You’re exploiting a vulnerability of human psychology. The inventors, creators, understood this – consciously – and we did it anyway.”
I encourage you to go to TimeWellSpent and my previous article on this subject on how we can be aware of how these systems can be harmful to you emotional wellbeing and limit the more damaging influences of social media.
Saturday morning rolled around and I headed into the office only to find what else but, blinking text. It was on the screen blinking in all its glory, and in the browser. How could this be, you might ask?
RAID systems on home servers and PC’s has become more common now. While we have been in a period of stubbornly elevated prices (from a historic standpoint), hard drives are always doubling in capacity on a regular cadence and improving performance.
There are several things you need to consider when setting up a RAID system. Will this set be my boot drive? What capacity do I need? How much fault tolerance do I need? What performance do I need?
The answer to these questions determines which RAID configuration you should set up. For my setup, I need fault tolerance and performance. This means I will continue to run RAID 5.
Question is, can I do better? There is software RAID available from Microsoft in Windows 10 called Storage Spaces. Also included with most Intel-based motherboards is a hardware RAID. So which should one choose?
Turns out someone has done the analysis between them, and done a good job too. Long story short, stick to hardware RAID, and RAID 5 is still the fastest and most fault tolerant configuration.
My 3 brand new 4TB 7200rpm drives are about to thank me. 🙂
From the Ars Technica article:
Intel has announced the 8th-generation H-series mobile processors will have a feature that’s nothing short of astonishing: they’ll integrate AMD GPUs.
The chip package will contain multiple pieces of silicon: an Intel CPU, a custom-built AMD Radeon GPU, and stacked second-generation High Bandwidth Memory (HBM2). Connecting the GPU and its memory is Intel’s new “Embedded Multi-Die Interconnect Bridge” (EMIB), a high-speed, short-range interconnect that Intel has designed to join different chips within a single package. Intel says that EMIB enables the creation of faster, thinner packages, enabling the multi-chip module to fit into slimline laptop form factors.
EMIB uses pieces of silicon to join the chips, rather than the circuit board traces found in conventional multi-chip modules. These pieces of silicon enable much denser packing of the interconnects. Overall, Intel claims that using EMIB shaves about 2.9 square inches (1,900 square millimeters) from the system motherboard and halves the power usage of a traditional design.
The company anticipates using EMIB for all kinds of integrations, such as processors with embedded FPGAs or other specialized chips. This AMD integration will be a good showcase for using the technology at scale. For AMD, it gives access to a market that tended to lean on Nvidia. Single-chip integrated graphics, even those found in AMD’s newly announced mobile Ryzen parts, just don’t offer the same performance as discrete parts with dedicated memory.
