rosalinekarr··on Does It Make Sense for Programmers to Move to the Bay Area?
> The Bay Area, with a large number of startups, is probably the best place to do this.

This is the bit I take issue with. I've done the whole startup thing, worked for 4 different companies in under 2 years, and it worked out great for me, but I did it in the Tennessee Valley, not Silicon Valley.

The Bay Area is not the only place with startup jobs. It's just the place with the biggest multi-national corporations still pretending to be startups.

rosalinekarr··on Four Million Commutes Reveal New U.S. 'Megaregions'
Yeah, I had the same thought when I saw my own region, Chattanooga, TN. This map shows our whole city as commuters to Atlanta. Almost no one commutes to Atlanta from here. It's a 3 hour drive without traffic and a 5 hour drive with traffic, and the only time Atlanta doesn't have traffic is 3 AM in the morning.

rosalinekarr··on Winning the Information War
Maybe the first step in fighting against disinformation is to stop calling it and thinking of it as an, "Information War," as if it's something with sides that's meant to be won.

The news these days is all about "fake news" and how we need stop it, but none of those information outlets seem to acknowledge the bias and falsehood in their own reporting. That's not to say there isn't terrible misinformation on the internet, but all this media buzz regard it seems like an overreaction which could lead down a dangerous road of censorship itself. If the goal really is to advance the truth, then shouldn't the best way of doing that be to focus on telling the truth rather than on silencing those not?

When ever I hear journalists saying we can stop misinformation by quashing all those other journalists telling lies, all I can think of is soldiers insisting we can reach world peace if only we could just kill all our "war-mongering" enemies.

This seems like a great way to vent about the election.
rosalinekarr··on Verified Voting
But pgz specifically said that the votes could be kept anonymous.
rosalinekarr··on The WhatsApp suicide
This is terrible, but blaming WhatsApp seems like a weird leap of logic. If someone harassed you over the phone, you wouldn't blame the telecom company. If someone sent you a death threat in the mail, you wouldn't sue the postal service. If someone hit you with their car, you wouldn't retaliate against the automaker.

It seems like the BBC is just bringing up the name of the popular chat app as a way of generating more clicks. If their goal is raise awareness for the woman who died and people like her, that's noble but a bit misguided. If their goal is simply to generate more viewership and revenue for their website (which it seems like it is), it's deplorable.

rosalinekarr··on The Strange and Sudden Disappearance of a Coding Bootcamp Founder
I've worked as a teacher/mentor for an online coding bootcamp, and from my experience, the advantage of these kind of programs is moving very, very fast. Self-teaching takes a lot of time because you often have to figure out what to learn about next, and university programs tend to take of lot of time because they expect you to take a broad range of classes (a little assembly, some webdev, a bit of high level math, etc). These bootcamps on the other hand, take you from your first HTML file to fully working Rails/Django/Node apps in about 6 months.

rosalinekarr··on Show HN: Your Social Media Fingerprint (maybe NSFW)
This 'fingerprint' changes as you login in and log out of various services, so it's not very reliable for uniquely identifying users. Regardless, it could still be used to profile you and then target content accordingly. For example, if you're logged into Hacker News, you're probably a programmer and you're probably more interested in an ad for web hosting than wedding dresses and visa versa for Pinterest.

Wait, you threw that demo together in under 20 minutes? Wow.
rosalinekarr··on Volume – The world’s first personal volumetric display
The resolution does seem super low, but I think they're trying to target the low budget market where it might make more sense. Their "How It Works" page says this:

> Volumetric displays have been around in research labs and a few small companies for decades. But they have always been extremely expensive — a staggering $100,000 per unit.

> Volume is nearly 100x less expensive than the systems that have come before.

Of course, their lowest price point is still $999, so I still wouldn't call that cheap.

rosalinekarr··on SRL – Simple Regex Language
This is really cool, but my brain keeps getting stuck on the word choice. Every time I see the `literally` keyword, I hear a teenage, valley girl accent in my head.

"Literally, at sign."

"Like, literally, hashtag, guys."

I can't even.

rosalinekarr··on The Myth of RAM (2014)
Worrying about the speed of light in processor caching these days is like putting a spoiler on your cart and horse to reduce drag. It might matter eventually, and that's kind of cool to think about, but it's absurdly negligible with the technology of today. Processors today are orders of magnitude slower than that.
rosalinekarr··on Show HN: Chalkbot
I wonder what this would look like if they could speed up the motors and smooth out the motion with some more taught string. Maybe they could recreate more hand-like motions.

Disney Research comes up with some pretty cool stuff. I loved their 3d printed speaker idea from a couple years ago. https://www.youtube.com/watch?v=zralu3wYUTU

rosalinekarr··on The other kind of JavaScript fatigue
Maybe what we need is a better system for assessing and comparing javascript projects. In the Ruby world, RubyToolbox has a great system that tells you about gem's popularity, update frequency, age and a ton of other stuff.

Is there a similar project for the javascript world?

rosalinekarr··on HyperTerm – JS/HTML/CSS Terminal
In my experience, it's very slow and clunky, but the real problem is that it attempts to impose a lot of styling and decoration _on top_ of the terminal.

For example, the command prompt isn't just a command prompt, it has this silly chevron decoration with autocomplete functionality. It can probably be turned off in the settings, but I find it to be a really annoying default. It just assumes I don't have my own prompt how I want it or my own autocorrect system.

I have to explicitly disable half the 'features' before I get anything actually useful to work with.

rosalinekarr··on HyperTerm – JS/HTML/CSS Terminal
This looks very well executed and really cool, but I'm honestly really tired of all the node/electron terminals. In its favor, this project looks a lot more clean and less opinionated than that 'Black Screen' monstrocity.
rosalinekarr··on OMG Digital (YC S16) Is BuzzFeed for Africa
It's good to see a media startup getting some attention. Not every tech company has to be some cutting-edge, shiny research project to be successful. (In fact, most of them aren't.) There's nothing wrong building a business by taking existing, time-tested technology and bringing it to a new, growing market.
rosalinekarr··on Reddit now tracks all outbound link clicks by default, existing users opted in
I'm surprised they weren't doing this already.
rosalinekarr··on The Girl with the Augmented Body and a DIY Manufacturing Habit
It's just a profile piece. It's not hard journalism nor is it trying to be. It's just a little picture of the life of a mildly interesting person. If you like, great. If you don't, you don't have to read it.

rosalinekarr··on Impress.js v0.6.0
You're right. I didn't notice they had added that file. It looks like pretty comprehensive documentation too. I retract all my previous statements. They just need to update their README.
rosalinekarr··on Impress.js v0.6.0
That was a reactionary. I've removed it.
rosalinekarr··on Impress.js v0.6.0
I thought this project was really cool when I first came across it, but there was one thing that really offended me about it and made me refuse to ever use it:

> How to Use It

> =============

> Use the source, Luke ;)

> Please note that impress.js was created for developers. Some basic knowledge of html, css and javascript is a prerequisite to install and use its features.

So, in other words, "please, reverse engineer my work because I'm too lazy to document my code."

Sure, they've put in a lot of comments, but there's still no clearly defined interfaces or guides for use. It's all comments like 'delegated handler for clicking on step elements' and big ascii art of yoda.

Documentation is not just for _newbs_. It's an important part of making a third party library. If you want other developers to use your code, then make it easy to use. To not do so is incredibly user-hostile, and it's not going to get you anywhere.

Could you imagine if people had attitudes like this in other fields of engineering? "Here's your new car." "Thanks, how do I change a tire or put in gas? Does it have a manual?" "Manual? Just read the schematics. If you know anything about mechanical engineering or combustion, you should be able to figure it out!"

Does the first chart account for inflation seeing as it's defined in terms of US dollars?
rosalinekarr··on Gravitational Teleport 1.0
At this rate, in a hundred years, we're going to be naming spaceship parts silly things like 'blip-blooper' because all the cool names for things will have already been taken by tech start ups.
