puls··on Tram Trains
It doesn't because it doesn't use any mainline rail track. Imagine if the T-Third went onto the Caltrain tracks at Bayshore and continued down the peninsula instead of terminating at Sunnydale; that would be a tram-train.

It would also be more or less impossible under current US regulations, but there's always hoping that that could be fixed.

puls··on 93% of Paint Splatters Are Valid Perl Programs
I love this footnote so much:

> This feature does enable a neat quine: the Perl program “Illegal division by zero at /tmp/quine.pl line 1.”, when saved in the appropriate location, outputs “Illegal division by zero at /tmp/quine.pl line 1.” The reason for this behavior is left as an exercise for the reader.

puls··on Tesla increases Supercharging prices to the point that gas might be cheaper
This article lost me at "Most homes are not wired to handle 120kW chargers, which are likely not cheap to set up."

If the author had done any research, he'd realize that there's no such thing as a 120 kW home charger. (The weasel word "likely" only confirms the lack of research.)

puls··on Ask HN: Would You Upgrade to the New MacBook Pro?
According to Apple's support site (https://support.apple.com/en-us/HT206587), the range of computers that support 4K at 60 Hz is a bit bigger:

- MacBook Pro (Retina, 13-inch, Early 2015)

- MacBook Pro (Retina, 15-inch, Mid 2014)

- Mac Pro (Late 2013)

- iMac (27-inch, Late 2013) and later

- MacBook Air (Early 2015)

puls··on Ask HN: Would You Upgrade to the New MacBook Pro?
I have the same machine you do and I ordered the new machine as soon as I could. Two external 5K displays is a huge unlock for more productivity.
puls··on LivingSocial Is Laying Off More Than 50 Percent of Its Staff
All airlines do this, all run by the same vendor: http://www.rewardsnetwork.com/earn/
puls··on Facebook Paying Employees to Move Closer to Work
Precedent: Facebook paid Caltrain a bunch of money to clean up those tracks a few months back.

puls··on Babel 6.0 Released
What was the downside to doing the same thing as before by default?
puls··on Babel 6.0 Released
When I read

> This means when you install Babel it will no longer transpile your ES2015 code by default.

what I really see is "This means that Babel no longer works out of the box and is now harder to use."

Was any thought given to how much additional complexity this adds to what was previously (https://babeljs.io/docs/setup/#babel_cli) a very simple way to get started?

puls··on OnHub
Comcast does this under the "xfinitywifi" network name as a default setup for anybody who uses the standard cable modem/router-in-one box, with thousands and thousands of access points: http://wifi.xfinity.com/

puls··on In Defense of the Midwest
Carnegie Mellon is absolutely in the midwest.

Pennsylvania is a big state.

puls··on Computational Complexity of Air Travel Planning (2003) [pdf]
The website they built is called ITA Matrix (http://matrix.itasoftware.com) and it's still available today even after Google acquired them. It's the most powerful flight search engine out there.
puls··on A better pull request
This is so telling: GitHub had a blog post yesterday[1] about pull requests and now Atlassian does today with a very similar title. The one from GitHub was about social dynamics and how to work together better, while the one from Atlassian is about technical minutiae.

Having used both GitHub and Stash, the difference in focus between the two companies comes across plainly, and these two blog posts only back it up.

puls··on Ask HN: Is Swift ready for production yet?
I've been coding full-time in Swift for the last three months and at this point our source base is about 10K lines of code. Given this experience, if I had to do it all over again, I'd probably choose Swift again.

The good:

- Swift is a far better language than Objective-C. It's much safer, the type system is great, and the functional features are a joy to use.

- Everything largely works as advertised; even for a super new language, the amount of total brokenness is minimal.

The bad:

- The current compiler's error messages are frequently bad to the point of being useless. Try to mutate an immutable dictionary? You get a type mismatch when you could get an error about immutability.

- The compiler is a lot slower than I think they mean for it to be.

- The debugger takes several seconds to evaluate an expression compared to almost instantaneous evaluation in Objective-C.

- 8 MB of standard library in your app binary.

The ugly:

- "SourceKitService crashed" messages in Xcode flashing on the screen at 30 hertz.

But at the end of the day, if you're hiring an outside company to do this, why does it matter to you what language it's written in? Shouldn't they be able to use their best tools?

puls··on Ask HN: Where do you see web and desktop apps in 5 years?
Same place we were five years ago: nobody cares what API you're programming to as long as your apps are good.

No, seriously. The iPhone SDK came out in 2008. Google Maps came out in 2005, ushering in the modern era of web apps. Mac OS X came out in 2001 and .NET came out in 2002, representing the major desktop platforms we know today.

The web as a platform is no different than any other platform in that it's just another platform with its own strengths and weaknesses. It just moves a whole lot slower than the rest, which is why we're still asking this question after this many years.

APIs and platforms come and go. Developers always have had and always will have choices about which ones to pick for developing their apps against. These choices have some impact on how easy it is to build various types of apps, but at the end of the day, the only thing that matters is how well your app serves the needs of those using it.

puls··on How Japan Plans to Build an Orbital Solar Farm
I can't believe nobody has mentioned this yet: exactly this was one of the standard disasters in SimCity 2000, where "microwave" was one of the power plant types.

You can control this with the HISTCONTROL and HISTIGNORE environment variables: http://askubuntu.com/questions/15926/how-to-avoid-duplicate-...
puls··on CarWoo is shutting down
I bought a car a couple months ago, and as soon as the sales manager saw a TrueCar page open on my phone, the negotiation ended and I paid the price on the phone. Pretty amazing how easy it was.
puls··on Square Debuts its Latest Hardware, a $299 Card Swiper for iPad Registers
The Square Stand actually includes a USB hub to plug the printer, cash drawer, and barcode scanner in via USB. It's much simpler than setting up everything to talk on the network.
puls··on Xctool: a replacement for xcodebuild to build and test iOS and Mac projects
"Runs the same tests as Xcode.app."

If this works, it's huge. Mad excited about this.

puls··on Vim After 11 Years
Why do people keep suggesting iTerm2? The built-in terminal app on the Mac does Unicode and 256 colors just fine.
puls··on Xcode 4.4 adds support for Obj-C literals
The implementation already exists in iOS 5, you just need to make the compiler happy; a header that declares them is sufficient.

Upvoted for the hidden Wacky Waving Inflatable Arm-Flailing Tubeman link.
puls··on Help the Hacker Dojo by sending them your recruiter spam
I would have gone guru, ninja, rockstar and put them in increasing order of annoying, but that's just me.
puls··on Summify acquired by Twitter
Along these lines, it makes me wonder how long it will be until we see the rise of free agency in the tech sector.
puls··on Sarah Lacy launches PandoDaily (with former Techcrunch writers)
Call me cynical, but having all of this disclosure up front leaves me trusting her objectivity a lot more than the seemingly obvious alternative where unknown back room deals leave you wondering.
puls··on Martin Fowler: The Fallacies and Reprocussions of Diversity Imbalance
I think his entire point is to call out that complicated web of social influences as the problem.
puls··on Web programs written in C++ are no big deal
Why must the standard of discourse always be "I'm right and you're wrong?" It seems to me that more often than not in this technological day and age, the situation is much closer to "I'm right and you're also right, and between our two positions there's probably something for both of us to learn."
