I can +/-5ms jitter using a cheap GPS receiver with serial over USB. Using the same receiver, but with a PPS wire to a GPIO pin on a raspberry pi, I get +/- 5µs jitter. If you are interested, I have a write up with live graphs in

I’m not familiar with Chrony. With NTPsec, the PPS driver docs say [0]: > While this driver can discipline the time and frequency relative to the PPS source, it cannot number the seconds. For this purpose an auxiliary source is required;

> It’s unclear to me why there’s so much delay and jitter in the PPS timestamping. I’ve messed around with this on a couple different GPS chips. I’ve found improvements can be made by increasing the baud rate to the maximum supported. 96

I get weird looks when I speak with people about my GPS PPS NTP servers. This is website amazing. Most of it is way beyond my comprehension, but it’s given me a lot to read up on.

This is off-topic, but I was looking at your sbts-aru project and remembered having read the hackaday post on it about fireworks. I'm curious if you've ever seen the RaspberryShake BOOM sensor? If so, any thoughts on how your proj

I must admit I've never used chrony, so I'm unfamiliar with how to configure it. I've read a lot say saying gpsmon's shared-memory-segment is a really great interface and to go with it instead of NTP's own GPS drive

You can see for yourself the level of accuracy in the ntpviz output. Notice the units of measurement on the graphs: * Clayface: https://www.developerdan.com/ntp/#./clayface/7-days/ * Catwoman: https:&#x

Good question, it absolutely syncs without any network connectivity. For better or for worse, I have it setup NOT to sync to anything else- being a stratum 1 source is enough. Now… I will admit I’m just a hobbyist with this stuff. Anyways,

I had this happen before. I used it as an excuse to learn how to setup NTP with a GPS receiver. I made a little blog on it if anyone is interested in the results. Be sure to click the sandwich menu for some real-time data: https:/&#x2

This is the changelog for 20.8.1, but it’s important to point out that that 4 of the CVEs were also patched in 18.18.2. Shameless promotion time, I have a little utility that can check a node version for CVEs or EOL: npx node-version-

The new feature for subscribed allowlists is going to pair really nicely with the existing support of ABP-style blocklists. I’m very excited for this release!

Three years ago I released a tool called PHP Version Audit. The idea is that it parses the PHP changelog and notifies you if you are running a PHP version that has a CVE or has lost support. Anyways, after running for three years, I thought

To answer your question, the levels are important for both regular usage and debugging when something goes wrong. I create a number of debug/info/warning/error log messages throughout the tool and allow the desired level of l

Yes, my library absolutely has to support the LTS version of Node, and I run the tests against all supported versions to ensure compatibility. So, one day I can use the nice things people are mentioning, but it will be years from now.

I’ve written a library with zero production dependencies. Of course I have Jest as a development dependency which pulls in all sorts of stuff. It would be difficult to make a zero-dependency library. As for not having production libraries,

It seems like the most reasonable choice. Incidentally, I have an open-source tool called Node Version Audit [0] which checks a given node version against known CVEs and end-of-life dates. It looks like the official change hasn’t been made

I think grouping server-side tracking with JavaScript based tracking is an oversimplification. JavaScript tracking is much more invasive and can access significantly more data. From something as straightforward as fingerprinting to potentia

While I agree that is the proper solution, most analytics do not respect the Do Not Track header. Beyond it being mostly ignored, Safari (which currently has 20% global browser share) removed support for Do Not Track in 12.1. So even though

Its pretty disgusting to track people against their consent, even more so to circumvent their protections against tracking. I added your domain to my blocklist: https://github.com/lightswitch05/hosts/commit/bb

I agree. I think its very likely 'import a ton of other block lists and then apply some sort of logic to whitelist potential problem domains', but I would love to be wrong.
