When I started with guitar, I said to the guy "I'm not sure if this is a phase or not, let me try the cheapest guitar in the store". He tuned it, walked all of five meters around the counter to hand it to me, I strummed it, and even with my unmusical ear, I could tell it was already out of tune. "I think I'll try your second-cheapest guitar!"

I also had a 'guitar god' friend with me that day, and I thoroughly recommend taking a friend who can play along to buy your learner instrument.

Server died...here's a repost:

Over this past weekend a good friend and coworker passed away. He always had a good heart and would do anything he could to help you out. It was certainly a shock.

Monday morning he didn't show up to work. He always calls or sends an email if he won't be in but nobody could get a hold of him. I got a bit worried since I knew he was playing Diablo 3 since it came out on Tuesday and I've heard of people dying from exhaustion and what not from playing video games so much. I didn't want to think that but it had occurred to me. Especially since nobody has heard from him since late Saturday. I had called his landlord and asked about him. (The landlord, Russ and I are all good friends and we've known each other for a while) I was heading over and she was going to let me in but apparently she got too worried and went in anyway. She found him at his computer. He apparently had a heart attack. Poor gal shouldn't have had to do that. I kick myself for not going there immediately. I had gone in anyway at the request of the Fire Department to find his identification and cellphone. Not a minute goes by that I wish my memory of him had not been sullied in that manner.

I sincerely hope that he went quickly and didn't suffer, unable to contact anyone for help.

He was only 32 years old.

Please, if only for yourselves, take time out of your day to get some exercise. Go outside and enjoy the sun. Ride a bike. Do something active. Video games are great fun when played in moderation. This may be an extreme example but take it as advice to not go overboard. Or at least don't do it alone. He took 3 days off and played Diablo 3 pretty much the whole time. He called in and asked to take Friday off as well. We are placing the blame on ourselves at work wondering if we made him come in on Friday would he still be with us today?

It saddens me that we tried to get him to be healthy. Work offered to pay for a gym membership. Friends coaxed him to exercise and eat better. He took us up on our offers, if only for a short while.

We should have tried harder.

He will be missed greatly by all who knew him.
Yes! No failure to launch tonight!
Reminds me of Dreamweaver
I'd like to add another way of thinking of it. Several years ago I was part of a group working on a project that was composed of people from various companies. One of the attendees was blind. It became clear VERY quickly that our blind friend was light years above everyone else technically and in terms of thinking about process. He'd sit there, listen to people go back and forth on this or that issue, then come in with an incredibly intelligent and appropriate solution, time after time. He was using an audio browser to go over the project materials when we weren't working. If you don't make your services accessible to the blind, YOU might be the one missing the benefit of this type of person's input.
There's a clear chicken and egg situation here.

Actually, $20+ /day is the price of _additional_ liability insurance. In most states liability coverage up to state defined Fnancial Responsibility Limits is included in rental price. Ask at the time of getting your car to avoid additional fees.

For instance, Avis says [1]:

Avis provides liability coverage for its vehicles as required by applicable law. In most instances, this will include coverage for the renter or authorized driver up to the financial responsibility limits of the applicable jurisdiction at no additional charge. In some states, the liability coverage provided is excess to any other applicable coverage.

Excluded are CA, TX, UT.

Dollar has similar policies, but they are less specific in their generic policies [2]:

B. Third Party Liability Claims: Unless otherwise required by applicable law, a renter and/or any additional authorized driver (and the respective insurance company of each) is primarily responsible for all third party claims of personal injury, including death, and property damage caused or arising from the use and operation of the DOLLAR vehicle during the rental. (To the extent DOLLAR is required to provide coverage, in spite of the terms of the rental agreement, it shall only be in an amount necessary to satisfy the minimum financial responsibility limits required by applicable law.)

I'm 6'6" with giant hands. I was struggling with a 5-fret stretch for a chord, and thought it couldn't be done. My guitar teacher was a tiny gnome of a man with small hands and stubby fingers, and he played through the same stretch without a problem while showing me something else. I asked him to show me and he said "yeah, it's a bit of a stretch, that one", but it hammered home that it's more about practice than physical limitation.

There's a kabillion factors to consider though. With that many users, yes the exact implementation matters less and the ancillary systems and how they interact are more critical. But, building the platform, being able to iterate quickly and deliver robust functionality along the way is important as well. Not that Ruby hasn't, but Django and Python have really proved their worth with some of the heavy hitters recently. Instagram, Pinterest, FriendFeed, Disqus... It's an impressive roster.
So are you saying that a product that's ahead of its time is "right"? I think that (with some very notable caveats), we can say that in general if the market doesn't want a product, there's something wrong (perhaps the problem isn't with the product itself).
Yeah...that's insane. Since they're a "pre-revenue" company, they're just burning money.

I think adoption is key, ESPECIALLY when you're only earning from subscription fees.

Only charging for a service and not offering a free version can kill adoption. I know very few online services, especially consumer-facing services, that don't give you SOMETHING for free.

You and I may know it's high quality. But if you're a skittish consumer and there are free or freemium choices, I think it's unlikely that a paid-only option will thrive.

I can understand indifference of news outlets. After all, unmanned launches have become fairly routine. Even cargo missions to ISS have become routine. The 'what' isn't the exciting part of SpaceX, the 'who' excites us. Most people probably don't get that.

What I can't understand is the disparraging nature of a lot of the coverage. Both Slate and the Wall Street Journal had really snarky commentary this morning about the delayed launch. There were many people poking fun at them on Twitter.

Meanwhile, as someone who actually follows this stuff, I was amazed by their ability to shut down the rocket after ignition without damage. I'm also impressed by the fact they're able to refire the engine almost immediately. You can't do that with every rocket ever made. Not only is the Merlin engine cheaper, it's better (than some). That's something to be proud of.

And even if the journalist doesn't know enough about rockets to be impressed that a failure didn't lead to the thing blowing up on the launch pad, they're acting as if government launches don't get delayed repeatedly. The Space Shuttle would seemingly only actually liftoff about 50% of the time they said it would. It's hardly a major set back that they pushed it back 48 hours. Why does it seem like people want this to fail?

> It is easy to prove that...

Reminds me of a similar comment in the margin of a old book: http://en.wikipedia.org/wiki/Fermats_Last_Theorem. :)

But it does sound both plausible and brilliant. How do you prove it (in broad terms)?
Works really well if you are a kid. You get really solid foundations then and you gradually improve.

This is why its important for your kids to watch Cartoon Network in English. I think this is how I and a whole lot of other 20-somethings learned the language.
This is a cool idea, but I'm skeptical about it being worthwhile for the majority of people. There's absolutely no new ideas here, or anything that hasn't been done before. It's just a slightly novel combination of them.

The "lights on the fretboard that show you what to play" thing has been done; and while it generally gets good reviews I don't think it's revolutionizing learning guitar or anything. Likewise plugging into an iPhone for effects, etc.

The hardest part of starting guitar is simply building up your hand/finger muscles and muscle memory. Having lights on the fretboard makes it nominally easier to place your fingers, but reading tabs isn't hard to begin with (this is essentially just tabs on the fretboard anyway) and learning to look at a tab (or sheet music) on paper/a screen and translate that to finger positions is an important skill to develop as a musician.

This will encourage beginners to look at the fretboard when they play, which is a bad habit to get into.

I also have concerns about this feeling and responding like a real guitar. This doesn't operate like a normal guitar, so there will probably be a lot of little areas where it differs so someone who's played this may pick up a real guitar and find that they are making all sorts of horrible squeaking and finger noise, aren't used to the action of a real guitar, etc etc.

If it was a choice between this and a real guitar for a beginner, I would go with the real guitar no question. If you happen to have ~300-500$ that you can just blow on cool gizmos, sure it'd be fun to play with.

If you've never touched a guitar before, this might get you from 0 to "Smells like Teen Spirit" slightly faster than otherwise, but I doubt by much. I think the returns will diminish over time, and this might even ultimately hurt you.

The main neat thing is using it as a midi controller/ to make cool sounds but there are plenty of other options in that area already.
Norman Solomon for Congress CA-02 : Home Page
There are more subtle ways of gaming ruining your life, as well: slowly losing the drive to do anything more than what's necessary to pay the cable bill, rent, and the gaming subscription. Slowly the only friends you have are people you know from your guild. When the only source & output of creativity and energy are all wrapped up in playing a video game.

I've also seen people similarly consumed by pornography, alcohol, gambling, day trading, and I'm sure other things I can't think of now. Pot. I think any of those things can have their place, but please maintain connection to people who can and will say something if you start going overboard.

For instance, I'm in a pretty good place right now and still gave parental control to a friend for the D3 release, just in case. Six hours a week is arguably still too much, but seems reasonable to me, and they won't budge because A) I asked them not to; B) they care. That I've hit that limit is a good sign that I may not be as well off as I thought I was ;)

Take care of each other, and yourself.
I once had an opportunity to present to Mr. Moritz (just last year). He adores the idea of entrepreneurship, and idolize great entrepreneur in general.

I wish him well, and I hope he stays involve.

The Dirty Truth About Web Passwords
Are there any quick, easy ways to destroy all the data on your phone to prevent this if you are arrested?

I currently have my passcode set the wipe the iPhone if it is entered incorrectly 10 times. So, if I was arrested and I could erase all my data quickly 'just' by tapping a number on the lock screen 40 times.
I don't know how it is on Android but on iOS for example, you can make phone calls only the Phone app. For example, the Yelp app gives you the business info and when you tap the phone number it switches to the Phone app. For the most part, that's fine but having an SDK like Twilio allows you to keep the phone calls and the user inside your app.

That can be pretty interesting in terms of user experience where your user stays in the same context instead of switching back-and-forth between your app and the Phone app.

It's not untenable at all. Are you familiar with investment funds that take positions on the likelihood of success in some litigation? In a nutshell, non-parties to the litigation make bets on the outcome of the suit. I believe there is at least one fund like this active in the UK. Guess who started it? A former trial lawyer.

This differs from donating to the EFF in that you have a say over what specific cases you want to invest in.

The startup black hole, it's a dark and confusing place
Recently there has been a glut of posts discussing the dark times during a startups journey, right now thats something I can totally relate to. I regularly meet with other startups in their infancy, they have all had an idea that's been validated by friends and loved ones, the initial buzz of launching has passed and in sets the fear and confusion of what happens now.

It starts with questioning everything, why is our traffic not exploding? where is the hockey stick growth I'd anticipated? then the realisation that you never actually validated your idea in the first place, there was no plan to get into a market, simply launching and tweeting should have been enough. This generally lasts for 2-3 months, followed by a succession of pivot ideas, each one is spun up to the point of identifying features and getting that excitement back and then shot down when you inevitably find a flaw in the plan, or realise it's been executed perfectly elsewhere.

Desperation starts to creep in, the runway shortens and pivots tend to get more extreme. It's easy to pick out the guys that are in this trench, they stop talking about what they are doing, and are more interested in you than they have ever been. Failing, going through this process and surviving seems to be the journey most people go through. If you can avoid the cracks, keep some focus and hang in there you've got a shot at being one of the few that make it through (it's that easy right?)

if you are feeling the pinch or can relate to this, share your thoughts ,maybe it'll help someone!
Having read the original I'll have to say that my takeaway from this post is very similar to what I thought about the book. The overall sentiment and advice are great and extremely helpful but the specific examples are bad and should be taken with a grain of salt. The thing I've learned from the book is that your approach to life and social situations can be improved, but applying a "conversational algorithm" to real life will only make you come across as naive at best and a farce with no personality at worst.
