3D printing is already there, its just expensive. Take a look at dmls (direct metal laser sintering -

What you see in the hobbyist 3d printing world is about 10-15 years behind the commercial world.
Well, my point was that the analogy shows the problem with the rest of the post - he's applying a faulty standard to judging if the changes are good ones or not.

If it's just griping that he doesn't like the changes, fine, but if his point is that these are bad changes that don't make sense for the product, then he needs to pick a better analogy.

Car suspension tuning is a very subtle and difficult black art. It's all about what's happening dynamically in response to transient inputs (go around a corner, hit a bump, etc.).

I believe Lotus does a lot of engineering consulting helping other manufacturers dial in suspensions. I wouldn't be surprised if Tesla had them consult.

Even some of the big car companies have trouble dialing in suspension on their own (I'm looking at you underdamped Japanese cars). European brands tend to be really good at this, and can take the same raw materials that everyone else is working with and create superior setups. Porsche somehow manages to start with the 911 where they stick the engine way out behind the rear axle (high polar moment of inertia, poor front/rear weight distribution) and make it handle beautifully. VW cars also tend to have great suspension tuning. Being able to keep the weight low to the ground in the Tesla contributes to a low center of gravity and I imagine must really help enormously.

Also the body under-tray is beautiful, like something you'd expect to see on a purpose built race car, probably helps a lot with the aerodynamics. I imagine more and more cars will get similar under-trays to improve aerodynamics and fuel efficiency.

It's interesting there is strong anti-dive geometry built into the car, probably to avoid problems with throttle lift oversteer caused by inexperienced drivers. I wonder if the current Model S handling leaves anything to be desired when driven to it's absolute limits and how the car would handle with some of the anti-dive geometry removed. Removing this geometry is a common mod on some cars.
Those batteries sure take up a lot of space. I wonder what their physical volume is -- compared to a 15 gallon gasoline tank.

The slide-out brake pads are a neat idea, but I'm wondering why, as the caliper still has to be removed during a brake change to pull off the rotor.

Those aluminum pieces can't be cheap. Neither can the 4-piston brake calipers. Nor the armored underbelly. It's definitely performance-oriented.
> You can feel free to make a stock, a trigger, a pistol grip, etc., but just don't make a receiver. On some guns there's a lower and upper receiver, in which case you can make the lower without the license. Make the upper without a license and you're in trouble.

This is incorrect, assuming you're in the US and no weird state laws are relevant. In general, it's perfectly legal to make your own guns from scratch. A license is only needed if you plan to manufacture guns for sale.

Feel free to make firearm (federally, state law may be more restrictive) but only without the intent to sell. If you use it for a few years and then sell it, that's fine. If you "use" it for a day before selling it, that won't fly. It is also recommended to add a serial number to the receiver so LEO don't freak out. I believe only firearms manufactured with an intent to sell require serial numbers.

The whole hubbub over 3D printed guns is silly. People have already been legally and safely manufacturing firearms as a hobby for many, many years.

Agreed that RTMP is an abomination that needs to be exorcised from the Earth as soon as possible. Unfortunately, it is probably here to stay until something like WebRTC gains critical mass.

It's not clear what the article means by "repackaging" a stream or "pointers" to tags (especially in the diagram that shows tag pointers being transported between users). While RTMP is cumbersome, shoving media data (tags) under a per-session protocol header is essentially the standard way of moving data from one session to another.

So I'm not really following this. Is this cutting out the RTMP entirely for receiving clients, and instead sending the FLV down via another transport, like HTTP or whatever? Or is it more of, "I wrote my own RTMP streaming server in C and Python", along with some implementation details which I'm not understanding? (Not that there's anything wrong with doing so. Options are limited in the streaming-server space.)
I think despite the weak analogy, his point is obviously valid and solid. Gmail has gotten shittier for everyone.

The amount of times my friends and I made pressure bombs (in a 600ml bottle) using NaOH and Al (exactly what was described in the article, and frankly, my first thought when reading this) at school and at home I can't even count on two hands.
It was initially shown to us by our Chemistry teachers as a method for creating H2.
The real danger isn't the expanding/produced hydrogen, it is the highly basic solution that is still reacting within the bottle.
If you're nearby, and it explodes, depending on your volumes, the resultant spray can be seriously ... painful. Safety goggles and a nearby water source is a must have.

I would just save the email that the invite was sent to and save the invite against it. When the user signs up with that email I would know they have an invite waiting for them. There's a chance they might not use the same email address to sign up but this makes a much cleaner flow for the user.
Still, it's a common courtesy that if you downvote someone, you tell them why. I think most of us are here for hopefully enlightened discussions, driven by a yearning to learn, share, and explore various topics. We want to be taken seriously, for the most part, and take seriously what we say. Yes, at the end of the day it's just "internet points", but that's belittling our experiences and interactions here to be so dismissive to suggest one should just ignore them.

If that was the intended design, then perhaps votes should be hidden from users as well, so that we'd never know if we were voted up or down; but, I think the design is intended to somewhat subtly clue us in about whether our opinions and statements are popular, controversial, or whatever. It's a feedback loop, and most forms of conversation involve such indirect feedback loops in the form of non-verbal communication -- though in real-life, it's heavily augmented by body language, facial expressions, voice tone and inflection, etc. We don't have those luxuries here, and so the only non-verbals we're left with are the up-arrows.

It's one thing to receive a single down-vote, hell you can't please everyone, right? However, when you try in earnest to participate in a conversation, and you receive the equivalent of a "shut up" from the crowd, then you're left wondering: did I miss the entire point? Did I accidentally offend someone? Was I factually incorrect?

For a healthy conversational atmosphere, it helps to resolve these issues, so that we can improve our communication -- and hopefully avoid the need for any downvotes in the future.
That check looks for blacklisted IPs of your provider. Gmail is blacklisted very often, thus making deliverability of your messages to some servers lower. Might be a poor wording on our side. We'll take a look at that.

It wouldn't be hard at all to sneak a few bullets on a plane. Have you flown recently? At many airports they try to force everyone through the body scanners, but if you refuse, you bypass both the body scanner and the metal detector and get a non-invasive patdown that wouldn't be sufficient to find a couple .22 bullets. The harder part would be assembling and loading the thing once you're on the plane without someone noticing.

I think what he means is that you don't need to be a class 2 SOT to manufacture silencers (as you would to manufacture machine guns, for instance). You still need to fill out a Form 1 and jump through the other hoops, but there's no "license" required beyond the usual tax stamp.

The reason race is being brought up is that black people are underrepresented among scientists, and that this student clearly demonstrated the sort of curiosity that drives great scientists. Punishing her for that would be counterproductive regardless of her skin color; it is made even worse by the fact that we generally want to encourage black people to become scientists.
I work for a suspension manufacturer in the aftermarket industry for trucks, and a lot of it isn't that extraordinary. The air springs/shock absorber combination that you see there are becoming more normal across wider applications, while already coming equipped on luxury vehicles for quite some time now.

The part that impresses me though is the steering knuckle (they comment on it towards the beginning), and its aluminum hollow construction. We build modified steering knuckles for trucks that provide additional lift height, but out of ductile iron in a cast mold, same as OEM specs/mfg process. So i'm kind of at a loss how they would make it hollowed out, while maintaining stability. Definitely expensive, i know billet aluminum knuckles for corvettes run about $1500/piece.
That's a workaround of sorts, not a solution.

As far as I understand, these UI changes are there to empower "multitasking" and bring Gmail closer to the way social networks and chat work. Now, I loathe the new compose, I like writing my emails in a structured way, with proper formatting, which this new feature doesn't let me do easily (or comfortably); I often use them as reference for docs and whatnot.

I'm not saying this doesn't work for some people, but when I see that a large number of people I communicate with can barely read or write properly as it is, I fail to understand how empowering multitasking will make things any better. I'm a bit tired of the "social networks way" becoming the end-all, be-all.
It's fantastic. Best thing I've ever driven, regardless of environmental impact. It's silent and odorless, responds instantly and precisely, and it seats 5 adults + 2 kids comfortably.

A niche benefit: I live in the mountains and it handles going down much better than gas cars, where you have to downshift and use engine braking to avoid burning the brakes. It uses 12 miles of range going up, and gains 4 back going down so the average is close to a flat road of the same distance.

For comparison the McLaren MP4-12C [1] has probably the most trick setup you'd see this side of a early 90s Williams F1 car [2][3]. Notice on the 12C how the rebound/compression dampers from each corner are cross connected instead of a roll bar, and the z spring at the back to resist high downforce.

Considering the Williams F1 active system was developed for the 1992 season, I'm kinda disappointed that no fully active system has ever hit a production car. The best we've seen is active damping on several cars. Bose had a pretty cool prototype [4], but never hit prod. The neat thing about electromagnetic damper/springs is that they can regen for a EV.

That's a fairly good reason for bleeding edge to be used as one track of a dual- (or multi-) track project which includes a short-turn-around, low-risk, low-reward track and one (or more) higher-risk, high-reward, longer-turnaround track.

This is equally true regardless of whether the project is "new".

> "I don't like guns and I think the fewer people have them, the safer we are"

The best case scenario, IMHO, is that everyone has the means to defend themselves against abuse. I value equality.

The worst case scenario, IMHO, is a single person or group with a disproportionate ability to abuse those who are defenseless against them - and they know it (your fewer-the-better scenario). IMHO, crime happens because people think they can get away with it. Good fences make good neighbors, IMHO, so I feel safer when everyone has a gun, for example, since disarmament creates an opportunity that wasn't there before.

Long story short, please don't say "we," since your ideas are strictly your own.
My high school had a dry ice fogger in the theatre department for making the close to the ground fog effect for productions.

Basically, it was an 80 gallon drum with a heating element in it, a basket that could be lowered and tubes for the fog to escape. You heated the water, then put the dry ice in the basket, clamped the top down tight, then plunged the dry ice into the water. Makes great fog that is mostly CO2 gas.

Well, if you don't clamp the top down tight enough, it'll go flying off, throwing hot water everywhere. This happened during one production and did quite a bit of set damage. Thankfully nobody was scalded badly.

Note, don't use this if you're doing a musical with an orchestra, or the fog flowing into the orchestra pit can result in woozy, oxygen deprived musicians.

Cool, you can print guns. Next you can print bombs and all kinds of weapons.

Sure you can make a statement by 3d printing a weapon. But with a little brain one should actually understand that there are a few other things which would be much more helpful. Just 'because you can' is fine. But this has been demonstrated already. Now it would be nice if people would demonstrate that they have a brain.
