Well quite, 4xAAA is a better choice in lots of cases. Just a point that it's still a very common design pattern, particularly in cheap devices. When you look at the capacities, 9V batteries are awful.

Bear in mind that 9V batteries also have far easier interfaces than AAA packs, requiring a single plastic/metal tab rather than an injection moulded retainer. In some cases, the price difference for both manufacture and battery cost makes it worthwhile.

As for current, plenty of devices run under 20mA happily. A microcontroller in active mode will probably use under 15. Most 9V devices aren't used continuously, my IR temp gun uses a single 9V for instance. However I've also seen smoke alarms and other home sensors that use them.

I'm not disagreeing with any of the criticism here, I would never use a 9V batt in a project, but there is good reason to consider it and people should understand why so many products still use them.

Stacked 9V batteries are typically the old Alkaline sort or rechargable.

Or no regulator at all if you use 4x AA NiCAD or NIMH.
In the UK, you can break your rail journey on the flexible ticket types, but not on Advance fares.

So you can either get a good deal by booking in advance, or by breaking a cheaper, longer journey - but not both.
Notch is an idiot. He should just ignore what people say on the internet, stop taking things so personally, and work on a new idea. There's nothing stopping him but himself.
Comments / feedback / questions appreciated. Thanks
I don't think it's sad at all. It's great that Notch is doing what makes him happy. And honestly, I think he's much more likely to continue to do things that benefit the world if he follows this intuition rather than feeling duty bound to build things that are as big and impactful as possible.

Honestly I think his is more of an artistic than entrepreneurial mindset. How many artists set out to "change the world" with their art? Not many. But still many do.

A risk of this is that the airline is only required to get you to the actual destination your purchased. If your flight is cancelled, they could re-book you with a routing that doesn't fly through your intended destination.
There are lots of things you can use code for as a lawyer, if you just think about it as "automating stuff." I wrote custom code all the time when I was at the law firm (and still do, but I'm in a more technical role now).

It was fun to take something where hordes of associates were being used as slightly smarter computers and automate it - there were several times when people were amazed that I turned out a properly formatted in-depth diligence report about multi-hundred-patent portfolios within a couple of days.

In my spare time, I built a natural language processing + graph analysis tool to help look for patent prior art. I spoke about it at PyCon - see <http://pyvideo.org/video/425/pycon-2011--how-to-kill-a-paten....

Right now I use an internal Github instance to manage CCLAs at Rackspace, and its just a matter of time until I automate some more stuff here.

I've noticed that simple googling for Clojure keywords is one of the more amusingly fruitless activities to do. Almost every term I lookup is a high level concept in some potentially vaguely related field. For example, on the frontend, reagent + state gives me chemistry results, during music overtone + piano gives me piano acoutics, etc etc etc.
Not to mention that you should always split tickets if possible, particularly if you change service providers. That and avoid London and First Great Western; their ticket prices are obscene.
This may be a weird reference, but what comes to mind is John Frusciante leaving Red Hot Chili Peppers at the height of their fame. He quit in the middle of the tour after Blood Sugar Sex Magik, after they became unexpectedly huge.

He just wanted to make music and play in small clubs. And he went back to playing guitar by himself and making solo albums. (Also heroin use, but that's a different story).

And he rejoined in '98 or so, had 3 huge hit records, and then left again a few years ago. He made a few more solo albums and experimented with electronic music.

Some people are not cut out for fame. The intrinsic joy of what they do is even more powerful than fame.

Freelancers: Classic Mistakes to Avoid on the First Call with the Client [video]
Really enjoyed his work with ataxia
To be fair, the AO has to deal with a lot of local personalities.

Chief judge of each court basically has their own say, plus whatever their admins/clerks want.

There are 94 federal judicial districts. So it's like having 94 different clients.

Nobody at the top (which is really the supreme court) is really willing to say "no, we are all going go this way", because the people at the top are judges, not technologists.
There is a tremendous amount of politics involved.

All that said, i'm not defending them. THey have 164 people working in IT. That's plenty to build a functioning database system.
I've seen some public judge apologists for the complexity of pacer: that nobody understands how hard this is to build, and that it's outside the realm of normal technologies.

That, to me, just demonstrates the problem: They think their problem is very very hard, and while not easy, it's not that difficult. People build systems that handle number, scope, and complexity equivalent to PACER every day.
Those product sectors are not known for compensation of inventors, and presumably he would like more revenue than the $1 unit cost Chinese assemblers or the $8/hr walmart shelf stocker. Not a high margin business.

I don't think that supply chain has the institutional memory and skills to ship anything other than large quantities of traditional, by the standards of their field, commodities.

The primary effect of getting a big company involved would be giving the gray market Chinese a big head start, so people can buy the product for 50% off on dx.com and related sites.

These reasons probably are what discourages the megacorps from entering this small field, or rephrased, those are the reasons why he's got something new instead of competing with existing mfgrs.

No it was a real question because depending on what you dislike about Minecraft, they could be an alternative (except much simpler) or fall under the same restriction.

1. I opened the issue, this definitely needs fixing.

2. Can you share a tool (preferably online) where we can see the color contrast problem, please? How did you check that they didn't meet WCAG 2.0 AA (so I can check it and fix it).

3. Not really CSS problem

4. Not a CSS problem. Anyway, I think that something can be done with CSS though.

This is a pure CSS tool, so the html and javascript problems should be addressed by the people using the tool, not by the css itself.

So please, don't use it, or help me improve it until it can be used. If you see any other problem, don't hesitate to comment, open an issue in Github ( https://github.com/picnicss/picnic ) or just send a small push request fixing a problem at a time (I'm trying to address every problem by myself, which is daunting).

Bungie had at least three hits (Pathways into Darkness, Marathon, and Myth) even if you don't count the successful sequels to successful games. Halo was likely to have been a huge hit (relative to Bungie) if they had been able to finish and ship it. (That may have been a big "if", as my understanding is that they were struggling financially after the Myth 2 installer debacle, but their ability to produce aside from finances was well established.)

Call it three or four hits, depending on how you count Halo, or the Halo-that-never-was.
Mongo may be the right call for your team, but just as an aside, the use case you're describing is perfectly doable with Postgresql using either text columns or json columns, and moreover, table denormalization is just as much of an option for relational users as for document store users.

People on the Internet get famous without necessarily trying or asking for it.

Famous people are turned into symbols, and are expected to act a certain way. People stop caring about the fact that they are people.

Famous people are held to a different standard, and their audience feels they are owed something by a famous person. In the case of Notch, for instance, people feel like he owes them his continual support on something like Minecraft, despite the fact that he likes to make little games, and one of his little games happened to explode.

Because people just being themselves on the Internet might result in them accidentally becoming famous, it's not trivial for them to stop being famous, unless they stop being themselves on the Internet.

> Jobs, conceptually articulating what would become the Internet in 1985:

Which wasn't a huge prediction; CompuServe's consumer offering had been available for years (and they had at least one smaller national competitor, The Source), and the BBS scene including BBS networks was already a thing. The value of computers as communication devices especially in a network with wide penetration wasn't something that the many observers at the time who made similar comments were extrapolating from scant evidence, its something that people had concrete experience with in the mid-1980s where the trend toward it becoming a key use of computers was widely recognized in social commentary, fiction, etc.

There's no way to sort out misdeeds, eg, fake cures from real attempts if we lift the normal trial and liability procedures. No one would use untrialed drugs if they had to take the full liability.

I'm ready to assume that medics treating an emergency epidemic are unlikely to knowingly turn to quack remedies -- homeopathic or bogus ones -- as opposed to items like ZMapp, a monoclonal antibody treatment by a well-regulated pharmaceutical company that just happens not to have been approved for human clinical trials yet.

http://www.cdc.gov/vhf/ebola/outbreaks/guinea/qa-experimenta...

Furthermore, let me add that conducting a randomized controlled clinical trial (for effectiveness and safety) when dealing with a pathogenic infection with a > 50% fatality rate is arguably unethical: you can collect data on clinical applications and apply a retrospective control sample of patients to determine whether it improved the outcome where it was used, but withholding a potentially effective treatment becomes extremely problematic under some circumstances -- the historic classic example was zidovudine for HIV, which was rushed through human trials into use in just 27 months because it was the first effective treatment for a then-100% fatal disease (HIV). (Some of the double-blind trials were short-circuited when it became apparent that continuing to alternate patients with placebo controls was likely to be injurious.)

They should start doing that, or something similar. Say you book a flight from city A to city B, but you really intend to drop off at the place C which is the middle-stop. Airlines could every now and then switch the route to go through a different city D without announcing it in advance. Getting stuck in a different city at random would quickly drive the point home to cheaters.

Apparently, nothing. After I had narrowed the issue down to torrents, I called AT&T and confronted them with the evidence. On the phone with me they directly said "we do that to prevent illegal activity over our service lines."

No amount of "torrenting is not illegal" worked, and I didn't really expect it to. They don't care about the legality, they only use it as an excuse to keep customers from getting the full usage of the service they pay for.

maximizing profit per passenger I suppose. There seems to be so much competition that even improving 10% on profit can mean a lot to airlines. One reason why we are seeing baggage fees now.
> Most people didn't even think a PC would be important for everybody

Literally every single teacher I had in elementary school (which overlapped the time of this interview) raised this -- that learning to use and deeply understand computers would be broadly important for everyone was, if anything more prevalent in the 1980s than today (while its assumed today that everyone will use computers, its controversial that anyone but the tech high priesthood will need to learn to use them specifically.)

> much less internet.

The internet specifically, maybe not; people were widely recognizing the value to the public of consumer-focussed online information services like CompuServe, but "the internet" -- while it existed -- hadn't yet connected with the consumer-focussed world.

Because flying a jet is much more expensive that an average traveller thinks. From what I read somewhere (can't find the source right now, but the math sounds right), the total value of collected fares for a plane full of typical passengers is not enough to even tank a jet and pay the pilots and the crew. Airlines operate at a loss. Flight fares are an extremely sophisticated kind of segmented pricing (done by machines, not humans), and people cheating like this screw with the airline's ability to keep flying some-what affordable to everyone.

For a detailed explanation of airline ticket pricing, take a look at this ITA presentation:

I wish I had a pithy explanation as to why this was but I haven't figured it out yet. "some people aren't cut out for fame" doesn't really do it justice, because the problem isn't entirely in the Notch's of the world, but also how we relate to them and how fame is characterized in our culture.
