If only you out there with #bufferbloat could fix it as good as this.

Dear Steam:

Please stop screwing up people's internet on downloads.

https://community.ubnt.com/t5/EdgeMAX/Taming-Aggressive-Steam-Client-Downloads/m-p/1802766
Smartqueue only addresses buffer bloat, it knows nothing about applications. Start by measuring your bandwidth and buffer bloat and trying to reach the best combination of speed/latency/minimal bufferbloat Also go into your steam settings under downloads: Take a look at the download mirror ...

wow. I did not expect this. I don't know what to say. 
 
Obama commutes Chelsea Manning's sentence

President Barack Obama on Tuesday commuted the sentence of Chelsea Manning, who was convicted of stealing and disseminating 750,000 pages of documents and videos to WikiLeaks.

I'm stunned. And approve.

Thank you, Mr. Obama.

Congratulations, Ms. Manning, and thank you as well.



I'd been meaning to post a suggestion for three actions Obama might still take over the next two days, including pardoning Manning.

I also request a clemency for Edward Snowden.

And would very much like to see a recess appointment to the US Supreme Court.

X marks the spot. It looked like a landing centered to within INCHES.

SpaceX launched 10 satellites to orbit today (Jan. 14) in a rousing return-to-flight mission that also included a rocket landing on a ship at sea.

Introduction As the centralized performance team of LinkedIn, our mission is to make LinkedIn pages load faster. We help each engineering team try to hit their page load time goals through various optimization efforts. One common question we need to answer when trying to decrease page load time is: where is the performance bottleneck? In other words, where should the engineers focus their efforts? Usually, to answer this question, a performance e...

I think dynamic ipv6 prefix assignment is a bad, bad, bad idea.

"But we need a session layer!" - the ISO folk said. "All you have to do is a add a really complex state machine to every box that wants to run #ipv6!" - they said, "and then we can have addresses come and go willy nilly just like we wanted with the ISO stuff 2 decades back! It'll be great!", they said... and then - during that - they punted handling finding anything ever again to the dns guys, who ran screaming from the room. "It'll work! trust us!" - they said. "Nobody will renumber a network more than every few years! And look at all the addresses you can use for, um... stuff!"

50+ reboots later... of my entire network...

First of all, reverse DNS is a stupid hack that makes me cringe. Honestly, a much better way to find out a machine's name would have been to send it a packet and ask it, rather than use the DNS.

Secondly, in spite of the fact that we do use reverse DNS, IPv6 has mostly ignored the problem of how to handle this. There is a good-but-many-years-old draft discussing the problem and solution space, but even when (if) that ever gets converted to an RFC there's still no clear solution for operators in any given environment. (Note that this draft by Lee Howard was a follow up of even earlier work by Andrew Sullivan).

datatracker.ietf.org - draft-ietf-dnsop-isp-ip6rdns-02

Anyway, getting back to whether or not dynamic route assignments make sense... I think they do. It's something that hasn't existed in IPv4 because of limitations with actually having enough addresses so it wasn't really possible. In general systems reconfigure themselves based on network changes seems like a good idea, and we are actually just really far behind on the technology curve in getting the tooling to work properly and to work together.

The perfect movie to see today is "hidden figures". I saw it last night. It tells an essentially American story about combatting odds and circumventing barriers in order to make great achievements. And: letting nothing stop you from achieving your goals!

See this movie. You won't regret it. And you'll feel better about all the progress we've made on so many fronts, while remaining aware of how much we have left to do as individuals and as a society.

I woke up this morning all choked up remembering one scene (SPOILER WARNING scroll down)



Dorothy Vaughan was prohibited from the white portion of the library... and had to steal a book on fortran to teach herself and her team how to program before their jobs were destroyed by automation.

This resonates with me in many, many ways.

(the rest of the movie resonated massively also, it's just this one scene that so mirrors my own story of self-education, and trying to beat back stupid barriers, and the anger I sometimes feel before resorting to http://www.sci-hub.io/ to learn something)

GO SEE THIS MOVIE! (and did I mention it also features math and rocketships!!?

I always wonder how fast you could go on a falcon heavy with a smaller payload and what the constraints are. The side rockets exit earlier with 60tons at lower speeds, so if you hived off the side rockets at the known best re-entry rate instead, how much smaller would the payload have to be?

Or:

If you flew 10 tons and were willing to lose all the rockets, at what
speed would you break orbit?

Or:

If you flew 10 tons and still wanted flyback capability to somewhere
in the world, at what speed would you break orbit, and where would you land instead?


I should just go hit the arocket list for this question, but I
keep hoping some tools are coming into existence that would let me plug the jpl NEO database and figure out rendezvous times for the top 1000 "best" asteroid targets. I'd really like to focus on reducing mission duration with more expensive launches....

Inspired by everyone bitching about there not being a big enough >50 ton market here:

Was told elsewhere: Use the NASA Ames Trajectory browser to get the Injection C3 (km2/s2) value for your desired NEO rendezvous: https://trajbrowser.arc.nasa.gov/traj_browser.php

Then use the NASA EELV Performance calculator "High Energy" option, input the Injection C3 value, and it will give the Falcon Heavy (and other rockets) payload in kg to that orbit: elvperf.ksc.nasa.gov - Performance Website - Query

Which is friggen cool!

singer, pianist, guitarist, writer, experimenter, theorist, hacker, maker, faker - in no particular order, on any given day. And I also write code.
Introduction
I used to be just a geek. Then I sold my house, left my cubicle, and travelled around the world, trying never to touch a computer, but observe how they were used, and how much better we could use them... now I'm still travelling, and still without a home - but trying once again to help hold up the sky, and finish what I helped start, so long ago.
Bragging rights
can surf big waves and fix big problems, and when I can't do either, can 'tom sawyer' others into thinking that they can do the same, and exceed their own limits.
