"Since ASKAP is an array of 36 dish antennas and the burst had to travel a slightly different distance to each dish, it reached each one at a slightly different time." “From these tiny time differences—just a fraction of a billion

I did this for a 4th grade class. We changed the teacher's profile pic on their class page to one of the kid's. Also displayed random emoji's next to the kids' names. They absolutely loved the emoji part and kept wan

Interesting! I didn't know about `CTRL+C`. You may like to also try `CTRL+[`. It's the telnet escape character and seems to be a general substitute for ESC on OSX, Windows, and I think Linux too. I find it pretty quick since my

The Ping Pong Ball Accelerator referenced at the bottom of the article is a really neat project. Wonder if elem school would let the high voltage source be used during science fair demo day...

I wonder if part of the issue is a kind of unspoken fear that the “dream” outcome may not be as common as people want to believe. If I am a young developer with more stock options than salary I want to believe that I will have the option of

It depends on what the JavaScript code is doing. The article discusses an example where code is loading Intl.DateTimeFormat which takes some time but is not immediately used. So if the 56KB code doesn’t do a lot of loading of expensive comp

For something humorous and a bit off the beaten path, I'd recommend the Retief series by Keith Laumer. [1] For the best SciFi in general, I'd actually suggest you check out assorted collections of short story. I don't have

We’ve found lambda’s x-ray feature to be very helpful wrt finding the source of slowdowns. I know it wasn’t available during the project you were writing about but wanted to mention it for others.

Keep in mind that if you have any kind of fanout at scale, keeping a few lambda instances “warm” probably won’t improve your throughout much. Update: found a nice article with metrics re: lambda-backed api gateway but the premise applies to

I’ve seen it generally recommended to use a different command rather than aliasing `rm`. Pretty sure there are a plethora of options for each OS but here’s a couple: For OSX, homebrew has a handy “trash” command line tool [1]. For Ubuntu, t

Hi bastijn, just following up. I don't see your email in your HN profile but I would like to take you up on your offer to get in touch with the appropriate lighting folk at Philips. I haven't heard anything back from my attempts

That is a very interesting approach to indoor positioning. The idea of just installing a light bulb seems very cost-effective. When you say, “used to” did you mean that the product was discontinued and/or isn’t available for purchase a

For what its worth I would watch just based on your description alone. May be better to just make one and get feedback than focus on making it interesting. Also, please let me know once you do. :-)

The de-acceleration between 0:10 and 0:12 is really incredible. To my eye, constant and smooth, with a hard stop once the passenger section is reached. What crumple zones are designed for, I guess, but I've never seen a better exampl

It's almost as if Thomas is saying, "If we reject the CO SC's ruling (which is what SCOTUS did) then we must also say the Exoneration Act is invalid". Which I think makes sense, even though SCOTUS didn't go that fa

Wow, I totally missed that it was from 2015. Thank you for the update and for your work! I find stories like how Niko met the authors fascinating, so thank you for that as well.

"... In addition, we draw from our experience to propose a new language extension to Rust that would enable it to provide better memory safety tools for event-driven platforms." I believe this part also warrants mention. Not only

Wow, I didn't know org mode did sequence diagrams. That is going to be really useful to document our code. Will be great to be able to check in the source for sequence diagrams since the online services I've found for making them

Our lambda functions are also unavailable. Lucky for us we didn't move any of our critical functionality to lambda yet although we are planning to once we have an EC2 backup in place...

I loved my old Tercel wagon. Didn't use that low gear all that often but fun to have. CV joints were always my problem, ended up having to replace them quite often. One time in college I was turning too sharply while parking and the

Thanks for sharing this. A few questions from someone interested in learning how to use BEAM-based systems in production: * How did you debug the issue? I know Erlang in Anger [1] is kind of written just for this but it feels pretty intens

The author doesn't explicitly say "tracing" but he specifically calls out Dapper and Zipkin in the section, "“It’s slow” is the hardest problem you’ll ever debug." Dapper - http://research.google.com&#x2F

This exactly. I've read two books about erlang and otp, including Fred's book and it wasn't until reading this that I felt I really "got it". I think this should be the first thing people point to when explaining t

We also use pallet. Harder to grok in the beginning since you have to learn the lib but it's pretty amazing what you can do with a full language. If anyone is frustrated by the speed of jclouds (which pallet uses internally), I recomm

It's pretty amazing but Alexander Graham Bell's work towards visualizing sound for deaf people is what prompted his "invention" of the telephone. This section [1] talks about the end result but the whole wikipedia articl
