I know it doesn't cost the big rig, but it doesn't save them much either (only a nominal amount from reduced tail drag as they don't form a complete air bubble), so why should they allow someone to basically metal-hump their vehicle for marginal to no benefit? For example: If it saves you $0.50 for every 5 minutes you tail a big rig, should the drafter be paying $0.25 to the truck driver?

I'm also talking about the electronic fleet, where it's controlled by computers in each vehicle. However there's also the mechanical fleet, where two (or more) vehicles actually latch on to each other, this would be great for electric cars and would also allow them to power-share. For example, 5 vehicles join together but only 2 keep their engines running but the power comes from all 5 vehicles' batteries equally.
There are times when I thought this would be useful, so its nice to see. Interesting to see how the implementation is done.

Nice to see that its actually faster too!

I missed the equity bit when I looked at the post. My main point is many of us see through inflated titles and some (myself included) perceive them negatively.
Question for everyone who binds the Caps Lock key to CTRL:

If you use the Caps Lock key as CTRL, then it feels pretty awkward for me to type some key combinations (like ctrl-x or ctrl-c) and still keep my fingers on the "home row".

Do you just get used to this? Do you type ctrl-x with your pinky and ring finger? Or, do you shift your hand away from the home row and type ctrl-x with your pinky and middle finger?
Well don't you think its good the "angry sarcasm" was -5? I think it is very out of place here. the -4 and +9 difference is worrying though (although the points have changed since then... damn timezones !).
Anthony Ha should have done a bit more research--and not admit he doesn't use the other site. Tumblr's bookmarklet is smart enough to discern where the media originates from. Ie. If it's youtube.com, it adds in embed code whereas if it's another video site it makes it a link.

That said, it doesn't have as much of a complete support of sites like Posterous does, so great job on the technical chain combo.
You have proved my point: that misinvestment alone is not the explanation. You also have to look for secondary effects from the financial collapse.

> given a Microsoft machine... the interviewer put me in a position where I was made to look and feel stupid, despite the fact that the recruiter had told me that I was interviewing for a Unix-type position.

Yeah, maybe.

...but do you think that had anything to do with you being female?

Do you honestly think that male interview candidates were given linux boxes, and they kept a windows box on a shelf in the closet JUST to trip up female candidates?

I suggest that the problem was that either the recruiter was an idiot, or that you applied for a government job.
It seems to be making NoScript go nuts. Delicious bookmarking still works, but it obviously doesn't need to get content from the page. I tried adding things to the whitelist but haven't gotten it to work yet. Any ideas?
I tried setting IntelliJ IDEA to Emacs key bindings, but I had to switch back to the default bindings. With the Emacs-like key bindings my fingers automatically expected a lot of things to work that IDEA plainly did not support (like kill ring).

My preference when I am not using Emacs is to make a clean break so my finger macros don't run wild, often unintentionally pressing key bindings that do other things than I expect.
One of the key things I've found works for us is differentiating what we WANT to have from users vs. what we NEED to have.

We used to have a webform that (in summary) asked the user what they wanted to download, how they got there, and how we can contact them later (as sales leads). Conversion ratio was fairly poor, so I refactored the priorities of what we were asking for into 2 forms.

The first form consisted of questions we HAD to know the answer to to service the user's request, and the second form consisted of info we wanted from them (name, email, contact info, etc.)

So between the first form and the second form, we'd kick off the download for the user (and show a progress meter at the top) -- which got them what they needed immediately, making the site seem faster overall.

Plus, since they were waiting for the download to complete anyway, the conversion goals for the information we wanted went way, way up as well.

Again, I didn't actually MAKE things faster, in fact, having to fill out 2 forms was significantly slower, but we kept users engaged and let them waste their idle cycles making us happy since we were already accomodating their request.
This is called mesh networking; the Google will turn up plenty of information, disinformation, products, research, etc. Right now it's pretty immature IMO, with a price/performance that is 10x (or more) worse than point-to-multipoint wireless. Technically, mesh is very cool because there are plenty of interesting problems yet to be solved, but practically I think point-to-point or point-to-multipoint wireless is better for rural Internet access.
I spent a lot of time at the beginning of my project (bigtweet.com) writing some unit tests in the Perl Catalyst environment. I think that it was very worthwhile at the time while I was changing structure, implementing exception handling, etc. Now that the project has stablilized and I'm mostly working on incremental functionality, I've largely skipped writing new tests (due mostly to time constraints).

I still run "prove" before any new release though.

I've also experimented with Perl code coverage early on with good success. Again, time constraints prevent me from pursuing this further for now.

If you have the time, I would highly encourage writing some unit tests for the core functionality.

I understand, but my point is, where do you draw the line on this forum? Practically anything can be changed in order to make it better. If people suddently started submitting items about how to design a better frying pan or municipal government pension system, would that be suitable fodder?

I realize that online communities develop over time, and some expansion is natural. I am just concerned about how wide the funnel is getting.
I would be the same as that (I am tending to use emacs more over time, relearning things from yesteryear).

My only complaint is the startup time for me seems very slow - perhaps I should just have it running after startup ? (I then use spotlight/quicksliver to quickly open up a file in it).
Yeah it did and that's my point — the name doesn't fit.
It's not meant to be a stop all. It's designed so that users is notified what is being executed. For an average user, I believe if he does not know what it is, chances are he will press cancel, unless people have a lot of faith in processes they do not understand.

Twitter might have been the original source for this news (from the link at your link):

From Twitter, we gather that Bill was talking about malaria prevention, one of the causes his Bill & Melinda Gates Foundation is pushing.

"No reason that only poor people should get malaria," attendee Tara Hunt paraphrases Gates as saying.
The price levels of everything except for running an instance for an hour have dropped significantly since launch. This includes bandwidth (the pricing tiers used to be $0.18/$0.16/$0.13 per GB and have since fallen to $0.17/$0.13/$0.11 with the addition of a fourth tier at $0.10/GB), S3 storage & requests (used to be $0.15/GB for storage and $0.20/GB for requests, now is $0.12 - $0.15 for storage and $0.10 - $0.17 for requests), Simple Queue Service (the changes here are more complex but Amazon writes "Under the new plan, 76% of customers with bills greater than $1 would have received lower bills, saving an average of 71% each compared to their actual bill", so it's generally much cheaper), Simple DB storage (used to be $1.50 per GB-month, now is only $0.25 per GB-month), even the Cloudfront CDN has already gotten cheaper since its very recent launch date (the lowest priced tier used to be $0.09 per GB and they've since added tiers from 5 to 8 cents per GB).

So while you're right that the instance-hour cost has remained flat since the launch, the actual costs of using the AWS platform as a supercomputer or server farm has fallen dramatically.
I started my search by looking at the providers that offered certificates accepted by Firefox and Internet Explorer. My next level of filtering was to look at cost and the ability to try the certificate for free during a trial period.

I settled on Comodo (instantssl.com). The evaluation period went perfectly. At the end of the period, I paid (I seem to recall $99) for a one year certificate. They required a couple forms of indentification (driver's license, utility bill) and the process went smoothly. I am using the certificate now at bigtweet.com.

You definitely want to put up a more professional face for your site. It doesn't have to be cutting edge, but sharper lines and cleaner/more interesting design will give people visiting a better first impression of your company. Like others have said, this is your company's virtual storefront. If web design isn't what you want to spend time working on, you might want to consider hiring a contractor to make a simple e-commerce site for you.

Man, who doesn't need an ordered hash from time-to-time?

The big problem is that most people assume a hash isn't ordered -- so when looking at Ruby source, I wonder if this is going to be confusing for awhile?
Malaria sucks, and solving it is more than a Biology challenge, it's a people challenge.

Last year I spent a few weeks volunteering at a health clinic in rural Ghana. People walked in with various ailments and issues. To them, it's simply easier and more cost effective to treat everyone as if they have malaria then to spend the time diagnosing the real issue. The results of this being that practically everyone walked out with malaria medication.

This is simply one facet in a complicated issue, but it's a big one. The people issues require crossing cultural and logistical barriers and are just as difficult to solve as the scientific ones.

Someone should write a book that outlines the appropriate boundaries for FaceBook.
This presumes someone (the government? you?) can figure out what to do with that labor. Traditionally, in a capitalist economy, we let the market figure that out. Right now, the market's in a bit of a state.
I can't speak for the Austrians -- all this stuff is beyond me. I follow along with the home game but I see parts in all camps that make sense.

Having said that, you know we already have this huge pool of money we can spend without borrowing anything. It's all the money people have made in various investments and savings over the years but don't want to cash out because of the capital gains tax. Why not eliminate that for three years or so? Wouldn't you see hundreds of billions of dollars come out of investments and go into buying new things? (Perhaps more investments, perhaps tangible goods) The upside of that is that the money will be going where people think the most value is -- that's the same places that are going to thrive over time. Now is the perfect time. I doubt folks are going to invest heavily in the stock market when it's tanking. Instead they'll go for houses, collectibles, other items of value. This is where your floor is anyway. So you're stimulating the pieces of the economy that have the most traction.

Or how about creating an income-tax-free zone for businesses with under 50 employees for five years? It's well known that businesses that size which are growing (think startups, except it might be a startup doing house-cleaning) are the driving force of the economy. Why not inject more capital into those businesses, allowing them to take their money-making machine -- their business -- and step on the gas?

Public expenditures on shovel-ready projects are the ideal, that is if you don't want to let the people spend their own money but would rather spend it for them on things that are "good for them". Practically speaking, however, seems like these public spending measures get burdened with political payoffs. This is natural since the body making the appropriations, Congress, is a political body, not a bunch of economists sitting around trying to see where the best public spending should go.

We may be able to drop money out of helicopters, like Bernake once said, but then again Keynesian theory has to have a limit. It's not a panacea, right?
Yes, my understanding of the site culture is precisely that downvoting is to show that a comment doesn't contribute to the discussion, rather than to show factual disagreement with the comment. This thread here is a discussion about a submission that suggests not everyone is interpreting downvoting in the same way, and that is a legitimate issue to explore here, as long as we are all in metadiscussion mode.
Whether or not the program is worth $25,000 is up to the market to decide, not just you. Basing the value of a program by arbitrarily declaring "that's just too much money for me!" does not address whether or not the program ultimately offers enough value to the actual students. That question will be resolved in time.
Aging is a degenerative disease most lifeforms have that's 100% fatal.

I've thought about this for a long time. (I've been an online moderator since 1992, on a variety of networks.) I would prefer a system of testing people on specific knowledge of specific subjects, and giving them visible badges to show other users they know about, for example, economics or education policy or computer industry issues. Then use the people's knowledge badges to weight karma scoring (and introduction to moderation privileges) behind the scenes. If you program it, I and my friends will visit the site.

I find this longevity research very disconcerting, especially the tone of this page in particular.

It's thinly veiled egotism to say "people should not grow old and die". What the advocate is really saying is, "I'm terrified of death and I will do anything to prevent it, no matter the consequences to society or humanity".

I'm reminded of Tolkien's Akallabeth.

Death is the fundamental strength of all species. Sure we should try to pursue advances in health care that improve longevity, but attacking the cause of aging itself is abhorrently idiotic.
You have to let users see the site first to get them interested. Logging in should be for posting privileges, not just for viewing.

See my other comment in this thread about why I prefer specific knowledge tests to puzzles. Puzzles neither screen out the people who most need screening out nor draw in the people who can add the most value to the site if drawn in.
As someone who lives in Interior Alaska, I feel your pain.

So, to take a cue from you and one from another comment on here: Wouldn't it be great to have a shovel that 1.) Had "wings" on it, similar to a snowplow, that you could fold out to widen the shovel, and fold in to make the shovel narrow, while also making it stronger for chipping ice. and 2.) That you could adjust the angle of the head on for digging vs. lifting vs. picking.

I'd buy it.

I've become enamored with PLT Scheme. Clojure main appeal appears to be that it is on the JVM (with all those darn libraries), not that it is a new/beautiful and novel language. I am a proponent of porting Clojure to run without the JVM - has anyone heard of such a project?

Only interesting thing about this article is that it may be part of a larger reversal of sentiment toward Facebook by the main stream media.

But I have felt for a while that the way you share on Facebook is geared toward kids & college students. Once you're grown up, the distinction between colleague, friend, and boss can get much blurrier.

I want to be able share some things with old friends from childhood, and other things with friends from work, etc.

I'm more sensitive to the fact that every email I send someone is an imposition, and had better be worth their time, because every email I get is yet another thing to deal with. I want a way to share things with people in a way that isn't "push".

I think a "Facebook for grownups" site that took these ideas into account could get a lot of traction. (Maybe such a thing already exists, but I haven't encountered it.)
This brings up a new question to me. How to decide on the number of and kind of backups?
The general view amongst economists is that Hoover's price supports were the one thing that caused the depression. FDR implemented limited socialism, which did nothing to alleviate the depression-- there was not much he could do about it at that point --but was rather meant to keep people in homes, and clothed.
Shouldn't be too bad. After all, it's a strict superset of the functionality of the old hash. The only confusion will come when someone looks at some code and notices, "Hey, shouldn't this be an ordered hash?" Then they go google "ruby ordered hash" and this blog post pops up and problem solved.

attacking the cause of aging itself is abhorrently idiotic.

Because it is good for society that 30-year-olds, because of aging-related processes, tend to have lower IQ's (and worse joints, poorer eyesight, poorer hearing, etc.) than 20-year-olds?
Which is why fiscal stimulus is temporary. It's necessary while the economy is at less than full employment, but once the economy starts picking up fiscal stimulus should drop off.
