yes, 1m for every 3.3ns error, we all know that. the problem is those GPS vendors only provide long term average error for their products, there is upper bound guarantee at all.

wondering is there any upper bound on the error, e.g. is it possible to ever have a timing error of say 100 microsecond seconds.

A quick question related to this blog - they mentioned that most modern NICs have hardware timestamp capabilities, that is consistent with what I saw. The question is what is the availability of those PTP ready & enabled routers/sw

Nice tech blog, really love it. From my understanding, basically this new iteration is better then their previous generation chrony based one because the uncertainty in the One Way Delay calculation is largely removed by having those Transp

In 2022, there are not many international matters that can be agreed upon by US, EU and China at the same time. Getting rid of this stupid leap second disaster is one of those rare ones. US, EU and China all agreed that leap second should b

glad you mentioned meituan, it is prefect example on how low you can go to survive in business. let's be honest, meituan is mostly used by not well educated & low income people who don't know anything about food safety & p

great story, for me another interesting part is that lots of those tools/utils used in their dev work were copied from that dude's home, surely that is very reproducible & auditable.

I used to pay $800-1,000 a pair, then I heard that the exact same glasses from the exact same factory just without that fancy logo costs you about $100 a pair. Bought a few of them, never looked back. People need to accept that you get ripp

Other than the annual university entrance exam and buying properties, Hukou is no longer enforced. The real difference only exists for tier-1 mega cities like Beijing and Shanghai, 97% Chinese don't live there.

I don't see any problem here as long as workers get freely to choose whether they want to live in factory dorms or in any other arrangements they can afford. Clearly such choice is available to them and there are numerous reports onlin

this is a sad news. adoption of ARM just started to pick up in server & laptop market, it could be a nice alternative to x86, yet short sighted decisions like this from ARM is going to cause huge uncertainties. RISC-V is great, I am all

this is not just source code, it is much better to be called magic. also love the story behind it.

very interesting stuff. wondering is there any in-depth walkthrough of the time keeping mechanisms in Linux?

realizing that I would be long gone by 2603, your reply made me really sad. then I realized that your calculation is obviously wrong. can I sue you for such such emotional distress?

1. NT kernel is neither novel nor used by anyone other than MS. Open sourcing the NT kernel would effectively kill the project as its security issues would be fully exploited with wide range impacts on literally everyone. 2. LLVM/Clang

To be fair, Apple actively participates in a long long list of open source projects, to give you some comparisons between Apple vs Microsoft - * MS still refuses to open source its windows kernel to the public. Apple has its kernel accessib

All my workstations at home use ECC Reg RAM purchased online from ebay/alibaba. Most of them are from vendors selling "decommissioned" server parts. There are several good incentives to do that - such second hand server parts

thanks for the info. this is exactly what I am doing. it does provide extra peace in mind knowing that my odds of having silent corruption is further reduced by doing such monitoring.

interesting, so they are actually using Ryzen with ECC RAM (when most people would be using Ryzen with non-ECC RAM) and that saved them from some seriously corrupted data written back to their persistent storage. wondering is it common for
