Inside the eight desperate weeks that saved SpaceX from ruin

They bunked in a double-wide trailer, cramming inside on cots and sleeping bags, as many as a dozen at a time. In the mornings, they feasted on steaming plates of scrambled eggs. At night, beneath some of the darkest skies on Earth, they grilled steaks and wondered if the heavens above were beyond their reach. Kids, most of them, existed alone on a tiny speck of an island in the middle of the Pacific Ocean. It was the middle of nowhere, really.

And they worked. They worked desperately—tinkering, testing, and fixing—hoping that nothing would go wrong this time. Already, their small rocket had failed three times. One more launch anomaly likely meant the end of Space Exploration Technologies.

Three times, in 2006, 2007, and 2008, SpaceX tried to launch a Falcon 1 rocket from Omelek Island in the Pacific Ocean, a coral shelf perhaps a meter above sea level and the size of three soccer fields. Less than two months after the last failure, the money was running out. SpaceX had just one final rocket to launch, with only some spare components left over in its California factory.

I can't decide on Python or C++

Learn Programming - 1 hour 26 min ago

Hi, I have a small problem not knowing which of these programming languages would be better for me since I'm already learning the basics of C++, and I'm now on dynamic RAM allocation. BUT! I still think if I should learn Python instead anyway... Please help me decide, I don't want to waste my time...

How does scrum help?

Learn Programming - 1 hour 45 min ago

I've been read some blogs about scrum and practically the whole Wikipedia page. However, I still don't get how scrum helps adapting to changes in requirements.

Say, something was made 2 sprints ago. There might already be features that build on this. If the requirement changes now, a lot of work will be lost.

I get how small timeboxes help with time management. But how does scrum actually help with adapting to changes?

Rocket Report: SpaceX says it would launch weapons, Bezos plays for defense too

Ars Technica - 1 hour 49 min ago

Enlarge / The Rocket Report is published weekly. (credit: Arianespace/Aurich Lawson)

Welcome to Edition 1.18 of the Rocket Report! Lots of news on medium- and large-sized rockets, including milestones for the Delta II and Ariane 5 rockets, as well as a round-up of SpaceX's big announcement of its first customer for the Big Falcon Rocket. Oh yeah, we even try to make some sense of propulsion based on quantized inertia. (We fail).

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Georgia's spaceport gets a tenant. The Camden County Joint Development Authority, which seeks to develop a spaceport near the Atlantic coast, announced this week that it has reached an agreement with ABL Space Systems to establish an integration and testing facility for the small launch vehicle that company is developing. The RS1 rocket, which has a test launch planned for 2020, is designed to place up to 900kg into low Earth orbit at a price of $17 million a launch, SpaceNews reports.

The N64 Controller Gets Brass Gears Through 3D Printing

Hack a Day - 1 hour 50 min ago

The controller for the Nintendo 64 is a masterpiece of design, and despite being more than two decades old, people are still using this controller competitively. Smash Bros, you know. Those competitive gaming enthusiasts are hard on their controllers, and after decades and tournaments, the analog stick will wear out. Previously, this required a rebuild or simply replacing the entire controller. Now there’s another option: a completely re-engineered analog stick, all made possible thanks to 3D printing.

[Nam Le] is a student at Cal Poly, and as would be expected for a very specific subset engineering students, had to track down new N64 controller every few months. The stick on these controllers wear out, so [Nam] decided to make the most durable joystick that has ever fit inside an N64 controller.

The design of the N64 stick is pretty simple, and exactly what you would expect if you’ve ever opened up an analog joystick. There’s the stick itself, which is connected to gears on the X and Y axes, which are in turn connected to encoders. This entire assembly sits in a bowl. After twenty years, the mating surface between the stick and the gears wear down, and the bowl becomes deformed. The solution here is obviously to engineer something sturdier, and despite what most of the 3D printing community will tell you, ABS and PLA just won’t cut it.

[Nam] re-designed the gears and bowl out of brass using lost-wax casting using 3D printed parts. These brass parts were mated with 3D printed gears and an enclosure for the bowl. The stick is nylon, an important design choice because this is the first part to wear down anyway, and it’s also the easiest part to replicate. Yes, this is designing an analog stick for the strength of materials and Real Engineering for those of you keeping track at home.

Right now, the joystick works as intended, and lasts much longer than the stock version. The goal now is to get this stick tournament-legal for some serious Smash time, in the hopes of not replacing controllers every few months.

Siri Shortcuts: Opening up Siri’s next chapter

MacCentral - 1 hour 50 min ago

In 2011, Apple announced that its newest iPhone would incorporate a brand new virtual assistant, based on an app developed by a company that Apple had acquired: Siri. This fall’s release of iOS 12 marks seven years since Siri’s debut, meaning that the virtual assistant would be roughly in first grade by now.

Over the intervening years, Siri has grown in fits and starts, expanding its features and its knowledge base, often with only a little fanfare from Apple. On rare occasions, Apple does devote some attention to the virtual assistant, such as when it produced a whole video dedicated to the relationship between action star—and impossibly cheerful human—Dwayne Johnson and the intelligent agent. But more often than not, Siri’s presented as a facet of Apple’s other products.

[700$/USA] For College and Gaming

Hi guys, I'm looking for a laptop with discrete graphics so I can play triple A titles at reasonable FPS.

I do not require a 2-in-1.

I do not mind if the laptop is heavy(if it benefits performance).

I do not care about the build quality.

I prefer straight up performance for the price.

I would prefer the GTX 1050 over mx150.

Thank You.
