Smaller animals have a higher power to weight ratio than larger animals, because strength scales as a quadratic function and mass as a cubic function.

For the same reason, smaller weightlifers snatch a larger multiple of bodyweight than bigger weightlifters. At the Olympic level it goes from about 3xBW down to 1.6xBW depending on weight division.

Also, humans are upright bipeds in a body that has the architectural hallmarks of a system for quadripedal locomotion. Cats have not compromised those advantages: we have.

What a neat idea! But if these trucks are PURPOSEFULLY breaking the laws and continuing to go through the tunnel, I am not sure that this solution will hold up for too long; after all, the clever truck drivers will know it is a mere illusion.

Furthermore, instead of a water screen, wouldn't a brick screen be more effective? Personally, I wouldn't mind going through water nearly as much as I would be running into a brick wall. Nonetheless, as I said before, a really neat idea and definitely a solution for some instances--limitations need to be addressed though.
Most folks probably write JavaScript for the browser.

Not only should you consider using object pooling for JS objects (like the author describes), but you also want to think about DOM element pooling, especially when you are dealing with large lists.
Unfortunately things in reality aren't going like that. It was hard for me to accept the idea that a company might dare to charge developers for „developing rights” (or something similar), yet Apple did that, didn't it? It seems that the (lack of) courtship and respect isn't a primary driving factor for people in such scenarios, money is. What Microsoft doesn't realize though is that their new boat isn't filled with gold (yet) to count on a gold rush.

This was inevitable. The group that pays the least, when it is folded into a larger more varied group, will pay more. There was no way this was not going to work this way.

However - how many young men who are not insured by their employers, pick up medical insurance? I know I didn’t. I’d imagine this is just guys who've gotten married and had a kid AND who are on the upper end of the income bracket for the uninsured.
Just to be nitpicky, Racket is not a Scheme dialect (hence the name changing from PLT Scheme to Racket a few years ago (already!)). It's not because it not only adds a lot to Scheme but also has somewhat important differences. For instance, `cons` pairs are immutable in Racket: there's no `set-car!` or `set-cdr!` as in Scheme (you can have mutable cons pair using `mcons`, `set-mcar!`, and `set-mcdr!` though). Also the macro systems that Racket uses (`syntax-parse` and co) is quite more advanced than the current Scheme rNrs one.
Temporary jollies don't get rid of the great chasm of loneliness. When they're gone, it remains.

Sure it does. It does make your life more annoying as you have to specify the port every time (and you have to remember it). Some software/firewalls/proxy servers may have trouble with the nonstandard port. If all that is not a problem then go ahead.

Another very nice trick to hide a service is port knocking.
Apologies, I seem to be suffering from a VERY short attention span. False alarm.
Rob Pike made an excellent point in one of his presentations on GO.

He pointed out that utilizing a language through a DSL or FFI that utilizes indentation instead of another method makes utilizing that language inside another language more difficult as it is easy to introduce bugs in the host language that are non-obvious to debug based on the indentation being incorrect but not obviously so.

I recommend watching all of his videos as they are very illuminating due to his primary focus being that of software engineering rather than theory.

It's a really cool idea, but I couldn't help but think they should move the water stop sign to well BEFORE the million dollar damage point

I thought the stop sign was only visible because of the dark background (i.e. moderately lit tunnel) behind it?

My first thought was similar - it needs to be seen sooner - but I presume that even some braking before slamming into concrete is better than none.
"Powerpoint is easy for presenter, hard for audience"

My observational experience is the opposite. A powerpoint must have "professional" design and "professional" multiple fonts and "professional" multiple colors, and "professional" multimedia such as stock photos and such. A lack of extensive customization shows a lack of motivation or a lack of respect. It doesn't matter if it contains actual content as long as it looks nice, because all actual content was already discussed interactively via email or phone call or written reports. So a presenter starts with generating 30 minutes of content then spends 6 hours adding meaningless flair, getting it approved by boss, bosses boss, then endless editorial changes to the multimedia, "move that stock photo a little to the left", etc. The graphics arts load on the presenter is huge and extremely expensive, yet provides no monetary value, especially for internal presentations.

On the other hand the reviewer doesn't really learn anything because any important topic was discussed in written email format in detail, the presentation is a mere formality / dominance ritual. So powerpoint is pretty easy on the audience, if its a powerpoint, that means you should tune it out.
Maybe you're right. If someone would keep blog focused only on his main topic.
Is this really news? It's pretty well known that young men have the lowest health care costs of any demographic. In a system of distributed or shared cost, the community who costs the least to maintain will inevitably pay more for it.

I'm ok with it, personally, because I have no right to my being just as no one does.
As others have said, this is inevitable. However, maybe the young men will appreciate it when they become old men.
> huge body builder style muscles

those are INCREDIBLY difficult to get. you're not going to get those just by lifting big with deadlift/squat/presses a couple of times a week.

it's like when women say they don't want to lift because they don't "want to get bulky".

100% pure nonsense. it's VERY VERY VERY VERY VERY difficult to get big muscles.

let me say that again...

it's VERY VERY VERY VERY VERY DIFFICULT to get big muscles. it has to be nearly a full time job for YEARS and YEARS of your life.

I'm young (in the scheme of life).

But I think the quicker you learn what's truly important to you, you start to spend more time on those projects/with those people/in that place/etc and you feel more fulfilled, and that you're making more of an impact, than you ever did before.
The web is a tough place to try to help people.

They sign up for your free virtual ant-farming business, then they don't use it. Why? Beats me. Beats everybody. You can either just ignore them or assume they need help.

If you ignore them, they're guaranteed to go away. If you try to help and they need it, good for you! If you try to help and they don't want it? They don't want to farm virtual ants anyway. So they spam-flag you and you go away. You made an extra effort.

This looks like the best solution to me to a tricky problem. It helps the most number of people. Assuming that everybody that initially wants something is going to somehow pester the crap out of you until they figure out how to do it doesn't seem rational. How else should a service act?

I love a good rant, but I'm honestly left feeling like this person hasn't thought this problem through from all of the relevant viewpoints.
It's a braver decision from someone who depends on their looks for livelihood. Also creates a mindset "if she could do it, then so could I"
I have a spare mobile that I bought from a popular British retailer, Carphone Warehouse, for 99p. That was a special offer, but it's still on sale for £4.99. There's no contract attached to it, and you can swap out the SIM card for any one you wish.

It's a Samsung, doesn't do anything fancy, but it calls and texts without a problem, the battery lasts for weeks, and the signal is rock-solid. It's an ideal spare phone. I keep it in the car for emergencies, and take it out to charge it once a week or so. It's so simple that I actually prefer using it to a smartphone!

It wouldn't be surprising. YouTube looks for video fingerprints of copyrighted data. Repurposing such technology to find copies of known CP videos would be pretty straightforward.

To me, the problem with the 'he could have just hit unsubscribe' argument is that there is no rational user that --wouldn't-- unsubscribe after receiving that many emails. So either they're totally ignorant of the sheer bulk of emails they're sending, or their strategy is to spam users until they unsubscribe.
Me and my friend were thinking that it would be cool to be able to comment on any webpage on the internet so we threw up a little web app over the weekend. Is this something that could fly?
I broadly agree with you, but I can't help but feel that you're patronizing the position needlessly.

I think it's perfectly respectable for someone to care if anyone uses what they do and to want to interact with users and care if their problems are solved - but, at the same time, desiring to do this within an order of magnitude of 40 hours a week, receive benefits, not have to worry about paying the bills, even if the client can't be bothered to, don't have to deal with the nitty-gritty of sales and bookkeeping and boardmeetings and fundraising and the landlord and sourcing a new datacenter[1] and dealing with the ISP[1] and making sure the Jenkins box is keeping up with backups[1] etc etc.

The career options for a developer (especially a good one) is a broad spectrum of opportunities, not just a black and white selection between the machine room of a bank or your own startup.

Funny, I also thought a stop sign wasn't severe enough (I wanted the water screen to project an oncoming semi to scare the sh*t out of the driver), but illusions like that would cause some drivers to panic and endanger motorists around them.

That and apparently some active enforcement about load heights. Load height is one of the things that is checked and enforced at truck inspection stops on US highways and interstates for this exact reason (to try to prevent over tall loads from damaging bridges).
People claiming the author should have just 'unsubscribed' are missing the point of trust. The author didn't just want these e-mails, he actually lost trust that Weebly was capable of sending informative e-mails at all.

This is a huge loss for Weebly, as they'll never reach the author again by e-mail, even if they were giving away a million dollar.

All in all, in Weebly's case, the e-mails are just spam. They do not have any function other than screaming for attention. Might work for 'growth hacking', but doubt it will do them any good in the long run.
However - how many young men who are not insured by their employers...

Maybe that comment works on reddit or other sites but I think many if not most of us here at HN work for ourselves or for startups who likely aren't able to provide across-the-board healthcare coverage for all employees. Given that the 20s and 30s are "the years to have kids", this group would include almost all budding entrepreneurs who want to get started in their 20s and have a family while doing so.
I don't think the water is used to make the driver think he's about to drive into a wall of water: I figured the water is used as a medium for projecting the huge stop sign in front of them?
Look at Leangains and combine that with Starting Strength. I put in 2 and a half hours per week (that's 10 hours per month. total) and eat 1-2 large meals a day consisting of just about whatever I want. I'm thrilled with the shape I'm in and best of all it's been really easy to get here once I stopped focusing on the kinds of time-wasters this article describes and instead started focusing on the Right Way (compound exercises and leangains eating guidelines).

Err, they're not going through the tunnel. They're too tall for it. They crash into the roof of the tunnel, causing severe damage to the infrastructure, their trucks and anyone who happens to pass by.

Totally agree on the casual thing. I don't even think it takes a full 7 minutes. It can be done in much less.

I don't agree on "true strength", whatever that may be. I don't care to be any stronger than I am, frankly. I can pull myself up anything; I can easily lift my dates. I don't need to impress on the beach. And I don't enjoy gyms, I'd rather do something else. So "getting strong" really isn't on my priority list.
I used to go to the gym and lift really heavy things off the ground for 2-3 hours a day 5 days a week. It was great exercise and I loved how strong I was after a few years of doing that religiously.

At some point life "got in the way", and between a kid and a full-time job my gym time started to disappear. I've tried a lot of creative approaches to keeping fit with shorter workouts, and what I have come up with isn't all that different than what is being prescribed here.

My basic approach is this:

1. Pushups - every other morning I do 5 minutes of pushups where I start at a set of 20 then bump up by a count of 5 until I'm at 35. Then I work my way back down to 20 allowing brief 20 second rests in between.

2. Pullups - same as pushups except I start at 6 and bump by 2 until I hit 10, and then work back down.

3. Squats - No weight, three sets of 50. This could be better, but I'm kinda lazy when it comes to squats

4. Mix in exercises using resistance bands. (shoulder press, lat pulls, tricep extensions, etc). I usually do these in three sets of 12-15.

Each workout takes about 15 minutes, and while I've lost some muscle mass I'm still a pretty lean/muscular 170. I'm sure there are all sorts of optimizations I could make, but honestly I don't really care at this point. I've found a quick workout I can do 3-4 times a week and it is keeping me pretty damn healthy.
This is not a waste of time. Let me explain.

Sometimes you only have 7 minutes. What's the difference between 7 minutes of this and 7 minutes of sitting, reading HN or Reddit? Lots.

I did this one yesterday, just to try it out. Now me, personally, I'm quite active. I did it three times with 30-second stretch breaks because that's what it took to work up a good sweat.

The point of exercise like this, to my mind, is that you can do it anytime and work it into your work day. Exercise during the work day, even minimal exercise sharpens your concentration and "shakes out the dead leaves" so to speak. It makes you sharper, and sharper at 3:30 in the afternoon (empirically determined to be the least productive time of the day by several studies) is exactly what most of us need.

What are your goals when you work out? Depending on that, this is not a waste of time. If you want to lose 50lbs, this will not help you. If you want massive muscles, this will not help you. If you want to be an "active person", this will not by itself achieve that, although it may make it easier to get into exercise later, when you do something short and see nearly immediate results. It's rewarding, and that's the first thing you need when starting an exercise program of any sort.

My point is, don't let anyone -- or yourself -- shame you out of working out. Yes, you read it in the NYT. It's a fad and it's mass-media. That doesn't make it stupid by definition. If it starts you off on finding ways to hack your body and make it strong, endurant, and resilient, then by all means, go for it.
You mean, before the 3 flashing stop signs BEFORE he got to that point?

A better idea might be a low bar that causes the truck damage well before they reach the tunnel. Only issue is how to make it safe and very obvious it's done the truck damage?
Aye, they had the excellent little distraction PlasmaPong (http://en.wikipedia.org/wiki/Plasma_Pong) shut down as they own the rights to Pong, a property they were doing sod all with at the time, thereby adding themselves to the list of companies that I'll think twice and thrice before given any money to. I'm guessing they are unlikely to try bully Google though as they aren't significantly smaller than them.
Instead of using marketing terms like "game console," try rephrasing your sentence like this and see how it sounds:

"But on the copyright side, explain to me why personal computer jailbreaking tools should be readily available?"

This is about control over the computers we buy, which is becoming more and more important. The purpose of the DMCA anti-circumvention clause is to remove control from the users or owners of computers, and put it in the hands of the manufacturers and their well-connected "partners." It says that you must have permission from someone else to run software or read files, or even to use printer cartridges.

The politicians who passed the DMCA were not merely naive; they were blinded by their own conservative worldview. They had no understanding of individual computer users writing their own programs, of software being distributed freely on the Internet, of sharing computing resources, etc. In their minds, people use their computers to access information stored on servers, or to consume entertainment sold to them by others, and everything must happen with the permission of someone else. It is the same mindset that leads people to say things of the form, "Well that XBox was not intended for you to run GNU/Linux on it, so stop complaining!"

I wonder is anyone else feeling that the stigma of being alone is much worse than actually being alone? Thing is, if you voluntarily spend your weekends playing games, coding, walking in the nature or any other non-social activity it reflects negatively upon you. I've spent a lot of holidays all by myself doing what I enjoy, eating the holiday candy I like the most, and just relaxing. From what I can tell, "normal" people would feel miserable spending their time like that, so they assume that I too must feel miserable.
It was cool seeing it in action (I wonder who thought of it, and got passed the bureaucracy to make it happen). I wonder whether they considered industry standard truck height when building that tunnel.
I think they actually shut down the lights in the tunnel before the screen goes off. You can see it in the video when the lights go off and tunnel is suddenly much darker.
Better a wall of water than a truck crashing into the tunnel!

No, don't just make it pleasant, make it easy for me, the customer, to control. Three levels is probably the most you need: 3) Trivia / social spam, 2) Announcements, 1) Security / billing / account maintenance; three little checkboxes, three bits in a "contact status" byte field somewhere in your DB. Do it. It's not the simplest thing that will work, it's the simplest thing that makes your customer feel like they have some control in the trust relationship you're trying to build with them.
