simpsond··on China is detaining a million Uighur muslims in a secret camp
Thanks, edited.
simpsond··on China is detaining a million Uighur muslims in a secret camp
I traveled around Xinjiang in 2010. I was in Urumqi during the one year anniversary of the 2009 Urumqi riots and there was some tensions. Armored and armed guard units were walking the streets, and the Uyghur people we talked with were very nervous. There was segregation at a business level there. The main strip for food was Uyghur on one side, Hon on the other. At the time, it seemed unsettling, but people were getting on with their lives.

Looking back on it, I realize I was part of a joined agenda. We stayed in a Military hotel, and had a driver/escort who was special forces. We had to get permission to do the things we did. We wanted to stay with a Kazakh family, but were denied and told that we could stay with another Kazakh family. It was all pretty wild, and my friend kept in touch with a Uyghur we met, and she desperately wanted out of Xinjiang... and was essentially living in fear.

I didn't hear about camps then, but I wouldn't put it past the government.

simpsond··on Passive Wi-Fi: Bringing Low Power to Wi-Fi Transmissions
This seems to require a near-by powered wifi device to aide in association of the passive device. For large deployments, that would require many powered units. In addition to that, there are requirements for multiple MACs, which may also lead to problems with limits in some networks. This is all clever, but it doesn't seem practical to me since the passive device depends on a near by powered device to do anything. I have worked on sensor networks with battery powered wifi devices. It's certainly tricky.

simpsond··on Bitcoin: A Peer-to-Peer Electronic Cash System (2008) [pdf]
Your posts about bitcoin prompted me to deep dive with it. I read the white paper a few times. I setup a node on one of my machines. I wrote some code to fetch a block template from my local nodes RPC service and generate some block generations for mining. I ran some basic cpu mining, etc. I feel like I have a better grasp of it all now. One thing I am struggling with is the incentive for miners once there are no more Coinbase/generation transactions. If the POW is maximally hard (energy intensive) then transaction fees will need to be high for miners to have ROI. If transactions fees are that high, then consumers are going to spend a lot to initiate transactions. This doesn’t seem like a win win to me. How is it going to play out once all coins are mined? Reduce the complexity of POW for post Coinbase txns? The security of the network is still there due to the amount of computation in the block chain up until the mine is dry. What are your thoughts on this?
simpsond··on Steam is no longer supporting Bitcoin
I don’t understand why miners wouldn’t include all pending transactions in their block. Seeing as how pow is a guessing game, there are plenty of permutations of the Merkle tree to generate plenty of roots. I guess to dissencentivize free loaders so miners can continue to make money once Coinbase txns are no longer a thing? It’s certainly not free to mine!
simpsond··on Building the World’s Smallest Atomic Clock: A Nitrogen Atom in a Carbon Cage
I’m not sure that is the goal. Having cheap and small atomic clocks simplifies time sensitive applications that can’t always rely on satellites or ntp. Clock synchronization is currently not a solved problem for the masses.

simpsond··on 3D Xpoint memory: Faster-than-flash storage unveiled
I'm not familiar with the physics of memristors or storage in general. I was wondering if a single line is used to read and write, increasing the voltage on write to change the state.
simpsond··on 3D Xpoint memory: Faster-than-flash storage unveiled
Do memristors read or write based on the applied voltage? I noticed that in some of the intel marketing material.
simpsond··on 3D Xpoint memory: Faster-than-flash storage unveiled
On the infographic the subtext of "1000x faster" is "up to 100s of times faster than NAND"

Then it mentions 10x more performance with a PCIe/NVMe interface.

Still all good things, but 1000x is probably more marketing than reality.

simpsond··on Fuzzing on Edison: field report
In terms of the specs, the Edison is great. After tinkering around with it for a bit I found I didn't really like the bundled software Intel released with it.

At the end of the day I want something just like this, but with a net-installish base linux distro, and something with better temperature range than 0-40C! It's too complicated for tinkering, and the temperature range is too narrow for commercial products. It falls into the middle, where it's probably not great for anyone. I'm sure Intel can fix that.
