Why the "NASA Tested Space Drive" Is Bad Science

liquiddark Re: Bad Science (315 comments)

They got micronewtons from watts, not kilowatts.

Why the "NASA Tested Space Drive" Is Bad Science

liquiddark Re:Bad Science (315 comments)

That depends,of course, on how well it scales. If you can get enough thrust from a small enough energy input, you can partially or completely remove the dependency on giant volatile chemical vats.

Ask Slashdot: Where's the Most Unusual Place You've Written a Program From?

liquiddark In a taxi (310 comments)

Waiting on a stand with a Dell Inspiron 7500, the biggest, heaviest beast of a laptop I've ever owned. Months later I was accused of programming while driving the taxi, which never occurred to me but, it occurs to me, would have been texting-while-driving before it was (un)cool to do so.

What If the Next Presidential Limo Was a Tesla?

liquiddark Ablative battery armor (330 comments)

So someone takes this, layers it with ablative armor, and suddenly you have a long-range, well-armored vehicle. What's the problem?

What If the Next Presidential Limo Was a Tesla?

Luckily having a giant tank of gas under the car is much safer.

It's Not Memory Loss - Older Minds May Just Be Fuller of Information

liquiddark Re:Flawed model (206 comments)

basic IQ can be measured.

And it is subject to the Flynn effect. So saying "It can be measured" hardly invalidates the idea that a better model of intelligence for aged brains will incorporate the various other things that are affecting the measurement.

Powering Phones, PCs Using Sugar

liquiddark Re:Orders of magnitude (199 comments)

Because scientists, unlike media, have a method for indicating precision of results, and order of magnitude is an intrinsically fuzzy term, whereas about ten times is not.

Powering Phones, PCs Using Sugar

liquiddark Re:Stop posting about non-existent fuel cells (199 comments)

Which it isn't. The past 20 years haven't been at a standstill. Predicting future product releases based on not having released the product would always give you an infinite horizon. It's not a useful metric.

Will Electric Cars and Solar Power Make Gasoline and Utilities Obsolete?

Will Electric Cars and Solar Power Make Gasoline and Utilities Obsolete?

liquiddark Re:Upfront cost. (734 comments)

$1000 pays off in a year, two at most. So unless you are suggesting that there will always be an inverse relationship between the labour cost and the module cost (which you'd really need to justify), there's really no case for saying labour cost is an issue.

Ask Slashdot: How Can I Improve My Memory For Study?

liquiddark Re:Try to get a learning profile (384 comments)

Given that both my parents and my significant other are all teachers, and several of my friends have had great success with alternative learning styles, I am going to go ahead and ignore this paper, which says only that there aren't many studies which meet their specific preferred experiment design. Differentiated instruction does accomplish what "traditional" learning doesn't - it provides a means of understanding material in several different ways and activates several different mental "nodes". So while the specific studies on the topic may not be perfect, the practical effect is engagement, which even the authors of the paper acknowledge. Engagement with material is a not-insignificant effect on someone undertaking learning for their own purposes.

Ask Slashdot: How Can I Improve My Memory For Study?

liquiddark Try to get a learning profile (384 comments)

Different people learn differently. Consider the possibility that you are simply not using the learning style best suited to you. There are tools to help with this.

The sleep thing as well, obviously. But consider that you may not have a fruitful approach to learning in general.

Ask Slashdot: Best Alternative To the Canonical Computer Science Degree?

liquiddark Meet people (347 comments)

A degree matters only insofar as you try to meet people who are interesting and interested in what you want to do. Research your professors. Join the CS club. Join the math club. Join the Fine Arts faculty for whatever social events they hold, because some of those people can do your site design, or your art, or help you understand how visual thinking works. Meet people. You need to behave as if you are interested in what you are doing. If you are interested, and if you apply yourself to those interests, then you will find that your degree benefits you.

If you're doing a program online, then you need to engage with people a different way - look at the teams behind tools you like, and reach out to them via forums. Participate in communities that cater to your field. Meet people who are launching web startups nearby.

Find people. Meet them. Engage with them. This is the work you will be doing for a long time, so get started on it.

Ask Slashdot: Should Developers Install Their Software Themselves?

liquiddark Re:Why not use tools that help do it? (288 comments)

You save the $5k on using cheaper hardware in Dev, but cost them $50k in downtime because that difference causes a bug to be exposed in Prod.

The problem with choosing the number $5k is that $5k is nothing. Spending a quarter mill to save a million down the road makes sense, but you just try making the case to the business some time.

1. If it was good enough for Einstein, it's good enough for you. Spend a little time reading patents. Maybe you'll change the world

Rapid Arctic Melt Called 'Planetary Emergency'

liquiddark Read your own reference. (757 comments)

I don't know what you're seeing in that graph, but I'm seeing significantly higher temperatures than normal after the melting point, which is exactly what TFA mentioned. The average temperature may be below melting, but that doesn't mean the temperature everywhere is below melting. A higher average temperature means more melt. If you look at years before and after about 1980 on that page, you see that the curve has in general been showing higher temperatures most years after the general melting point.

The Problems With Online Math Classes

liquiddark Re:I had the exact opposite experience (285 comments)

He's made a lot of cogent points about the course he took. Maybe you should respond to those instead of resorting to character assassination. Instructors who actually care about the classroom are the right people to judge course material. Students have too many other concerns to evaluate objectively.

Ask Slashdot: What's new in legacy languages?

liquiddark liquiddark writes  |  about 6 months ago

liquiddark (719647) writes "I was listening to a younger coworker talk to someone the other day about legacy technologies, and he mentioned .NET as a specific example. It got me thinking — what technologies are passing from the upstart and/or mainstream phases into the world of legacy technology? What tech are you working with now that you hope to retire in the next few years? What will you replace it with?"
