rosalinekarr··on Solar System Internet on the ISS
I'm no expert, but I believe this was created to deal with the massive delay in communications between Earth and Mars. The ISS is in low Earth orbit, so it has less than a second of delay in radio signals. Mars is 20 light minutes away, so there's a 20 minute delay between with all packets sent.

rosalinekarr··on United States of Paranoia: A growing tribe of troubled minds
I know this is largely anecdotal and not very scientific, but just listen to [what trans people have to say about it][]. There are some people who do regret transitioning, but usually the reason they give is the discrimination they experience because of transitioning, not any genuine dissatisfaction with themselves.

There is [a small propaganda war being waged by transphobic conservatives][] to create the illusion of a large percentage of trans people that regret their transition, but just look at their references. You'll find every link is either to the Daily Mail or some other hate group referencing even more hate groups in a big web of circular reasoning.

Generally, there's not a lot of hard data to work with on issues relating to the trans community right now, which is a little frustrating, but hopefully there will be more soon as the scientific community is finally starting to recognize the LGBT community and conduct real science on this stuff.

rosalinekarr··on United States of Paranoia: A growing tribe of troubled minds
I'm a trans woman, and I can talk about this a little bit, but for more, I'd highly recommend you read [Whipping Girl by Julia Serano][]. Serano is a trans woman and biologist that has studied and written about transsexuality extensively.

So first off, what if you applied the same question to sexuality? We could easily argue that gay people are 'mentally ill' and need to be 'treated.' In fact, for years in the United States, that's exactly what we did. Gay people (and trans people) were frequently [subjected to electro-shock therapy to 'cure' them][]. We can even take it further than that. If I come by my political beliefs by reason, then surely anyone who disagrees with me politically must therefore be insane. So maybe we should give those damned INSERT_POLITICAL_PARTY_HERE electro-shock too, right? Just until they see our way of looking at things.

Clearly, there's a line somewhere between treating someone's disease and treating _who they are_. Some argue that that line is 'posing a danger to oneself or others,' but that brings up the confusing subject of assisted suicide, which is a whole other discussion. There's also some that argue that we only treat 'abnormality' and 'normal' is simply whatever the majority of people are, but that doesn't really solve either of the cases above, because trans people, gay people, and political dissidents are generally speaking the minority everywhere. There's also lots of other possible rules that don't really makes sense either.

Personally, I'm inclined to believe that there currently aren't any good answers to these questions and there won't be any until the field neuroscience advances. When we can look at people's brains and genuinely study how they work, a lot of stuff becomes more clear. In the case of transsexuality, [some brain structures have already been identified][] that exhibit one pattern in women and another in men and tend to match along a person's _identified_ gender rather their _assigned_ gender. That provides some evidence for the concept of _neurological sex_ which was already a topic of discussion among researchers in the area of gender studies even before these structures were identified.

So, what do these structures mean? How does gender work in the brain? How does anything work in the brain? Where is the line between sane and insane? Honestly, I don't know, but I think we'll have a better idea in a few decades, and until then, let's just try to be understanding and compassionate with our fellow human beings.

rosalinekarr··on CurrentC Ends Beta Tests, Will Deactivate Accounts
> I'm in awe that some sales person was able to sell Walmart, Target, BestBuy, CVS and all these other stingy retailers on a payment system like CurrentC/MCX.

It's not as hard as you'd think. I previously worked for a start up that sold Walmart on a POS system that was absolutely terrible (the codebase didn't even have any tests). The big retailers like Walmart have a sort of "throw money at everything and see what sticks" approach to technology. They regularly sign contracts to try out new tech but only in one or two stores. If it works well, they scale up to more stores, but that almost never happens.

rosalinekarr··on Coming changes to Apple's App Store
> For the first year of a subscription Apple will maintain its 70 / 30 revenue share; after one year, the new 85 percent / 15 percent revenue share will kick in (applied per subscriber).

This is the exact opposite of what Apple should do. App startups in their first year need all the revenue they can get. After the first year, most of those companies have either reached profitability or gone out of business.

This policy is going to mean more revenue for the large, established app companies, like Instagram or Snapchat, and less revenue for any potential usurpers. They're effectively suppressing innovation and locking in any monopolies they've helped to build.

rosalinekarr··on Why I Quit My Job to Travel the World
[80% of Americans have some form of debt.][1] The average total wealth for all Americans is actually positive. [It's a little over $300,000.][2] But that number is really the skewed one, as it's significantly shifted by the 0.1% of the Americans [which own 90% of America's wealth][3].

As for the median, I can't seem to find that statistic, but I would argue that it's actually a less accurate picture than the average.

rosalinekarr··on Why I Quit My Job to Travel the World
> Some have meagre savings (like $5.000 - $10.000) and use all of them to fund the trip (like year-long).

You really don't understand how bad it is these days. The average family does not have $2,000 in savings, much less 5 to 10. In fact, [the average American household with debt owes an average of $130,922][1]. Over $15,000 of that is in credit card debt alone.

Being broke is actually doing pretty well nowadays. We live in a world built on debt, where the financial sector makes up over 30% of the economy and almost everyone is beholden to large banks. In a few decades, we'll be right back to feudal system, if things don't change.

rosalinekarr··on Feds spend billions to run museum-ready computer systems
> Using floppy disks and old hardware and software doesn't sound like a problem if it still runs and does what it's supposed to do.

It sounds like a problem to me for the simple fact that replacement parts are near impossible to find, and it's clearly costing the taxpayer a lot of money. That alone should be reason enough to upgrade.

It's also a huge security problem because many of these machines were designed before modern security procedures were invented. How am I supposed to maintain a cryptographically secure password system on a machine with a processor too slow to run a hashing algorithm?

> I'm skeptical that building a modern system would really save money since the temptation for feature creep is too great.

So, because we might be tempted to add a few features, we shouldn't upgrade technology? I don't understand where this weird pseudo-luddite mentality in the tech world comes from. I see it all the time in tech forums, and I just don't get it.

"If it's not broke, don't fix it" is a fun, catchy phrase, but it really breaks down as soon as you try to apply it anywhere. "Hey, you should really change the oil in your car." "If it's not broke, don't fix it."

rosalinekarr··on Did the Clinton Email Server Have an Internet-Based Printer?
Yeah, as important and fascinating as the whole story is, every time I see "ClintonEmail.com," all I can think is that surely the Clintons of all people should have the influence and power to get a hold of just "Clinton.com."

I mean the current owner of clinton.com is some investment firm that could probably do just as well something like ClintonGroup.com or ClintonInvestments.com. If I was her, I would fight for the email address "hillary@clinton.com."

Then again, I'm a programmer, not a politician.

rosalinekarr··on Rails has won: The Elephant in the Room
Rails isn't the fastest or the smartest framework. It has weird choices, confusing aspects and some downright terrible defaults, but for me at least, it is the best framework and it has been for years for one simple reason: DOCUMENTATION!

Every few years or so, a bunch of these articles come out shouting from the roof tops, "Rails is dead!" and "Long live Rails!" They often like to praise some new framework, like Hanami, as the answer to all our woes, but they never seem to address documentation.

In my opinion, documentation is where Rails blows every other framework away. I have never been forced to read Rails' source code to understand how something works (I have read some of the source, but for fun, not out of need), and I can't say that about any of the other framework I've worked with. There's always some obscure method or class somewhere in them that does something unintuitive that I always have to look up. In Rails, finding the documentation on that method is as simple as a Google search, but in django, expressjs, or any of the others I've encountered, that documentation usually doesn't even exist at all.

Efficiency, scalability and reliability are all great, but when I'm starting a web app from scratch, they're really not that important. I can worry about those things once I have funding. In the meantime, I only need them to be good enough, and Rails defaults are usually good enough.

What I really need when I'm starting a new project and I'm working on a shoestring budget, is speed. I need to build something fast so I can get funded. Once I'm funded, then I can think about implementing JRuby or splitting code out into microservices or rewriting with another framework, but by then, I'll have the money to take my time. Until then, Rails is the perfect framework for me and I'll keep using it until it's not.

rosalinekarr··on One-third of SF Bay Area residents hope to leave soon, poll finds
Come to Chattanooga. We have municipal fiber, cheap housing and no income tax. Our state government is so conservative businesses can get away with pretty much anything, and our city government is so liberal there are funds and grants for just about everything. As long as you can get over the occasional rebel flag bumper sticker, it's the promise land.

rosalinekarr··on The Problem with Electric Vehicles
Ugh... here we go again...

> Problem 1: Transportation will load the grid and generating capacity in rather nasty ways

Electric cars are not a _complete_ solution on their own. They are _part_ of the solution, along side more renewable power sources like solar and wind. I drive an electric car and I charge it almost exclusively with solar panels at a local free charging station provided by the Tennessee Valley Authority. (I live in Chattanooga, TN.)

Also, as for putting load on the electric grid, electric cars actually help with that. Many can be configured to feed power back into the grid, and as a result, they can balance out the grid load throughout the day with their batteries.

> Problem 2: Rapid charging is actually not so rapid, highway re-charging stations will have to be much larger than current gas stations

Shift your thinking! Electric cars won't be charged at gas stations like gas cars of the past. Most electric drivers charge at home in their own garages or driveways. I have neither, but I still manage to charge my car in street parking with an extension cord, an exterior wall outlet, and a few of those little safety mat things so strangers don't trip over my cord.

Charging stations will still be important for cross-country trips, but the average driver doesn't travel that far often enough for it to clog up charging stations across the country.

> Problem 3: Gas stations are not generally in the neighbourhood of electricity generation stations.

See above.

> Problem 4: Re-charging will not work nearly as well when vehicle utilization goes up due to sharing

See above.

> Problem 5: We don’t actually have all this infrastructure yet

Well, duh. That's why we need to build it. That's not an issue with electric cars themselves. That's a problem with our infrastructure that we need to fix.

> Problem 6: Range

This is something we need to work on, but it's not as big of a problem as people realize. More than 90% of US drivers drive far less than 100 miles per day. The few times I do need to travel farther than that, it's actually kind of relaxing to stop at a mall or restaurant with a charger, plug in, and have a 30 minute lunch while I charge.

> Problem 7: Trailers

Really? This is problem for most drivers? This is a niche problem for the few people that actually need to haul trailers. So those people can just use regular cars.

> Problem 8: Service

I drive a Nissan Leaf, and I am very active in the Leaf driver community. I have never heard of a Leaf having major maintenance problems. Chevy Volt's are known for having some issues, but in my opinion, that's your fault for buying something from GM.

> Problem 9: Tax Breaks

How is this a problem? Tax breaks will eventually go away? So what? The whole idea is to make these cars cheaper now until manufacturing gets cheaper and the prices start to go down on their own. This is really grasping at straws.

rosalinekarr··on Login Forms Over HTTPS, Please
The best solution is just to make everything use HTTPS. Using HTTPS for all traffic also helps to obfuscate which connections are the important ones.

Certain unnamed three letter organizations and nation states have the computing power to crack HTTPS encryption if they really want to, but using that power is expensive. Making sure all your traffic is encrypted makes it a lot harder for potential snoops to decide which traffic is worth spending the time and money decrypting and which isn't.

By using strong encryption for everything, even just reading wikipedia pages, you're doing everyone a favor by helping to make user privacy that much harder to violate.

rosalinekarr··on NSA Chief Stakes Out Pro-Encryption Position, in Contrast to FBI
Even on a case by case basis, the power to break encryption raises some serious questions. What if the current President or some future President goes digging through the emails of their opposition in an election year? What if the NSA starts investigating the records of politicians with a anti-NSA stance? With access to passwords and accounts, you even have to ask what if an agency like the GCHQ planted evidence in someone's email or tweeted an embarrassing photo on their behalf? [They have the tools to do so](http://arstechnica.com/security/2014/07/ghcqs-chinese-menu-o...), and with power like that, they could basically destroy anyone who opposes them before they even start.

I don't think perfect encryption is an impossible dream. I think it will be very hard to achieve, and we have a long way to go to getting there, but it's important work, and right now companies, governments and people should be pouring everything they can into making it a reality. We need a lot more research into encryption, especially [information theoretic secure](https://en.wikipedia.org/wiki/Information-theoretic_security) algorithms.

rosalinekarr··on Terrorists Mock Bids to End Use of Social Media
No, I didn't miss it. I'll admit that the article isn't directly calling for an end to encryption, but, at least the way I read it, there's some subtext about it. It seems like they're approaching encryption with the assumption that it's bad but we can't do anything about it, not that encryption is a good tool being used for evil.

> A trickier issue is presented by the encryption deployed by Apple, Facebook, Google and a range of smaller services that thwart law enforcement’s ability to access a target’s communications, even with a court order.

Why do they describe it as 'thrwarting' law enforcement? It's not thrwarting anything, it's just not providing them a back door.

Maybe I'm reading too much into it, but this article feels like it has something between the lines.

rosalinekarr··on Terrorists Mock Bids to End Use of Social Media
I was generally thinking about the things Glenn Greenwald describes in his book, [No Place to Hide](http://www.amazon.com/No-Place-Hide-Snowden-Surveillance-ebo...). For example, even though Greenwald is a respect journalist and regular contributor to the Guardian, when the Snowden scandal first broke, the NYT insisted on referring to him only as a 'blogger.' They also published a lot of op-eds bashing Greenwald's work as dangerous and non-journalistic.

Sorry, I don't have any better links or sources right now. I'm on mobile.

rosalinekarr··on Terrorists Mock Bids to End Use of Social Media
At this point, the NYT is just a mouthpiece for the executive branch. They've been pushing a ridiculous anti-encryption, anti-privacy agenda since Glenn Greenwald.
