Mozilla now has Time-Travel-Debugging (aka WebReplay) in javascript in Firefox DevTools. See an example here:

Note: only on Mac for now, sure to have bugs, but very cool. The work of Brian Hackett of Mozilla.

At Netdev in Montreal this summer, Van Jacobson presented some new ideas that mostly obsolete all the previous thinking on traffic shaping: TBF, HTB, codel, TCP small queues, and so on. Instead we can use "timing wheels"[1] to implement a lock-free, single-queued, highly precise timing mechanism.

Basically, at the time packets are produced, we tag them with the time they need to be released from the system, then we use a CPU-efficient data structure that inserts packets into the right spot in the middle of a single queue, instead of maintaining a bunch of queues and merging them later. Apparently this takes less memory and keeps the cache warmer. An example is Google's Carousel paper[2] although apparently it could be used for many things. Jacobson suggested using it to reduce the CPU and memory overhead of wifi per-station queuing, for example.

She was separated from her son for 9 months while seeking asylum. She’s still haunted by everything she missed.

Privacy at the border got a big win in court last week. Read the details of how EFF teamed up with the ACLU to defend traveler privacy.

The Senate will vote on Wednesday, May 16th. Call your senators today. If you can't bringyourself to call, write, but calls are more effective.

Everyone - especially Robert Mueller - needs to watch the chilling 1969 film "Z" by Costa-Gravas. Especially the startling and terrifyingly pertinent last 4 minutes. I mean it. Just spreading the meme of reviving this one forgotten classic may do more than anything else, to help prevent it from coming true in the next year or so.

We've been warned. Now you have been.

Paul does repairs on old Amigas, among other things. Over $4000 of the $5000 needed already.
