TraceMonkey is/was a tracing JIT.

JaegerMonkey is a method JIT.

IonMonkey is an SSA-optimizing JIT.

Type Inference is additional code that analyzes JS both globally and locally for types, and feeds that info into the JITs to make them more effective.

Previously Firefox used TraceMonkey, then TraceMonkey+JaegerMonkey, and now JaegerMonkey+Type Inference. The plan is to move to IonMonkey+Type Inference (not sure where JaegerMonkey fits into that).

In my old neighbourhood in Birmingham, around 75% of the deaths are of either young or elderly pedestrians. I'd like to see if there is a higher instance of injuries at those locations as well. As it may be location based, rather than possibly driver or pedestrian error.

I think a lot of it is the educational system. Educators treat math with voodoo gloves because they don't like it, and kids learn that attitude from them, leaving everyone involved with a "don't make me get too close" attitude towards math.

I was exceptionally fortunate to have a math teacher in high school who is probably one of the best high school teachers in my state. She loved math. She was excited as hell to get to teach it every day. I had her for 7 of my 8 HS semisters, and I credit much of my appreciation for math to her. I was still never a good math student - B+ at best due to lack of discipline in cross-checking answers and the like - but I loved (and still love) math. Calculus was such a blast for me that I took it twice in HS (the second time around for college credit).

I think the other half of the equation is that math is hard. It requires a level of mental discipline and precision that most people don't possess, and have no interest in possessing. I think that for most of us here, who have at least some interest in programming, this isn't obvious. We think in discrete terms and proof-like concepts, but most people don't. Math takes more brainpower and more self-discipline than most any other primary education subject, and people naturally follow the course of least resistance.
Agreed. It is very easy to spend money when it's given to you, but if you are bootstrapping you are definitely a lot more mindful of how much cash you have to spend.

However, it really depends on what you are doing. Some industries such as bio-tech basically require you to have a lot of money to even begin prototyping.

Here is the problem: "Try it without your plugins/extensions" and "Try a clean installation" have been the standard responses out of Mozilla when faced with any complaints for oh, say, half a decade?

Who knows, maybe firefox really did go to rehab, cleaned up his act, and worked out his problems, but it's too late.
I didn't say American schools were performing "adequately" (whatever adequately means), I just said they weren't underperforming. I.e., US schools perform as well as Asian schools for all categories of student we have data on.

I have no doubt that Asian families (in the US, Singapore, Japan, etc) send their kids to Kumon and are terrorized by tiger mothers. Net result: in all these nations, the children of tiger mothers score about 570-600 on TIMSS. So US schools systems educate Asian students pretty much the same as Asian schools.

There is not enough data to compare the results for non-Asian students, since we lack data on (Asian School, Black/Hispanic/White student).

Similarly, people of European descent tend to get scores of about 470-530, with Finland being an outlier at 546. Among this group, Americans of European descent are #6 (at 524). Again, data on (European school, Asian/Black/Hispanic student) student is lacking.

http://super-economy.blogspot.com/2010/12/amazing-truth-abou...

So the data suggests US schools do not significantly underperform either Asian or European schools, at least for the categories of student we have data on.

I.e., if US schools are inadequate, then so are the schools of most of the world.
I for one would support the Red Cross if they decided to endorse a sentiment like "maybe your video games should care about bystanders and not treat them as expendable pieces of trash, because that's not really cool. please consider this! thanks."

At the same time, a would-be Hays Code would be rightly ridiculed and ignored...
The big question is whether it is actually unreasonable for them to have 2.4 or 4.8 million in inventory. As he points out 700k isn't that much - not really enough to compensate for the proposed difference between reasonable and unreasonable excess inventory. Without much knowledge, I doubt that over estimating demand by a factor of ~4 is unreasonable.
Yes, nine is the natural answer. The quote was explained to me in terms of ten women, so I went with that.

Nine, ten...the important consideration is the fallacy of assuming that increasing spend provides a commensurate yield in productivity and output.

A few quick thoughts on email, office, and intro etiquette
On the other side, I really wish my office were like this. I hate having to sit down all day - my back really does start to hurt. I have a stand-up desk at home and I like it much better.

Even better than a stand-up desk is having a small treadmill. It's not like they go fast - it would be about the same as a slow walk. Suits would be fine, you don't sweat at all.

This is the best thing I've read in a while, Godin is exceptionally perceptive and open. The following resonated especially for me:

"For me, I feel opportunity and don’t want to waste it. There’s this buffet, this all you can eat candy shop, this endless selection of mp3s… what are you going to choose, what are you going to do, what impact are you going to make?

How dare I waste it. How dare anyone. "

I mentor high school kids and would want to pass this exact feeling on. It's not easy, though. It requires a certain mindset to tune to this and not everybody can or will do it evidently.

Other than that, the author of the submitted article simply describes the school board member as a "success" who makes money.

The person was described in somewhat more detail than that:

He continued, “It seems to me something is seriously wrong. I have a bachelor of science degree, two masters degrees, and 15 credit hours toward a doctorate. “I help oversee an organization with 22,000 employees and a $3 billion operations and capital budget, and am able to make sense of complex data related to those responsibilities.

I'm in favor of standardized testing and am as annoyed as you by the shallowness of this article, but you're undermining your own argument here.
Why is standing all day horrible for your health? I'm assuming your are talking about the post above yours referring to a work day. I stand 10+ hours a day, with no foot pain, and don't stand on a pad or in shoes. Just because of this, I won't lay down a blanket statement that it IS good for you (based on one person's opinion), so why go as far as saying it is "horrible for your health" with no backing facts?

Sure. But it's going to make women on the team much more uncomfortable, because of the stereotype. If I were a blond man, and my manager would reel off a string of blond jokes whenever I made some mistake, it'd be pretty irritating. If I were a blond woman, it'd be probably be still more unpleasant.

That's the point of the article. She found her particular string of experiences (and all of the other similar experiences not listed in the post) frustrating enough that she needed to leave the job, and the team suffered her loss (probably without ever understanding why she left, or how they could retain another equally-talented female techie).

This is not going to be intuitive to every manager or techie. It's worth discussing.
Interactive html5 music video
we have just developed and released an interactive HTML5 music video for the song evelyn from ABBY.

it is written in javascript. we had to write our own syncing methods because the song has about 120bpm and 5 tracks have to be in sync the entire time. it also adapts to your browser's and machine's perfomance in order to be able to play on older machines, too.

it might take some time to load because the videos are 170mbs in total.

let us know what you think... thanks dom.
> These types of arguments are very similar to the arguments made by those who have requested laws regulating violence in video games in the past. Those people argued that the lack of consequences in the game would influence player behavior in real life.

Of course. Mowing down countless pedestrians in Grand Theft Auto, then climbing up to a high building and sniping the police officers that come to arrest me most certainly affects me - it lets me blow off steam in a way that doesn't actually harm anyone.

TouchFire actually takes up much less space than a Bluetooth keyboard. The wall thickness of the silicone keys is half the thickness of a credit card, and it is flexible so it can fold with the iPad's cover.

And you can quickly retract it off the screen when you want to do non-typing tasks. There are magnets in all four corners which snap it into the retracted position. Take a look at the iPad 1 video on the Kickstarter site. That shows retraction in use...

In a speech class (I think it was Toastmasters), they had someone with an audible 'clicker' they would click every time someone used a 'stop-word', which also provided a count at the end of the speech.

This was very effective training to stop (or at least greatly reduce) their usage.

Um, "limited academic ability?" The guy has a bachelors in science, two masters degrees and is working on a Ph.D. He's not stupid, regardless of Mark Twain's wit.

Now, I completely agree that a single anecdote isn't cause for policy overhaul. But if a guy who has been successful in college can't pass a test designed to weed out students who shouldn't go to college, that's a clue that maybe something, somewhere isn't working right.

In my experience, its over abstraction that is the real hard nut to crack. I have heard people using very abstract statements which everybody seems to agree on, but most of them understand it differently.
It is always ritual-gum-flapping time for some folks.
Humans can withstand much more than 2.4Gs although the time is exponentially and inversely proportional (for example, 3Gs is a space shuttle launch for a number of minutes, 10Gs is the maximum force allowed during space capsule landing, but only for a few seconds).

Therefore, I wouldn't say "uninhabitable," but probably less friendly (and not immediately lethal) to humans. Also, different animals have different thresholds -- mice, for example, have a much lower tolerance for G-forces than whales.

I recommend reading "Packing for Mars" by Mary Roach -- very insightful book that discusses all sorts of things about planet habitability, space travel, space suit design, psychology, and among many other things, G-forces.

I had a cube at one point at a company who wouldn't buy me a stand-up desk, so I just put a box on top of my desk and put the monitor / keyboard / mouse on it. I obviously don't know your situation, but unless you are explicitly told you can't stand-up, you should try.

For me, I looked ridiculous standing up in the cube farm, but by the time I left, five people on my floor were standing.

I would agree that in recent years designers are becoming a lot more important and having a good designer as part of your team is probably more important than having the right business guy or sales guy in the beginning. I'm not sure if I would say that it is the Golden Age of Design though. Developers are still a little more important than designers I would believe at least at the early stage of a company.

The rules of grammar that we "learn" are an attempt to model a process that we don't understand very well. It's hard to say that grammar defines a language when a speaker/writer can at will break any rule and enhance their communication by creating new constructions and vocabulary on the fly. Rules are at best a simple description of some expectations. Context, observation, and additional communication can completely override any rule.

Grammers are useful in communication, but they certainly don't define and constrain it; they are like standardization in tool making and manufacturing. But words combined together, in a context, can behave in ways that no grammar can describe.

In fact I'd say that grammars are more conscriptive than they are descriptive. Literacy and education teach us to speak and write in grammars for formal, ritual use. But when we need to get work done or communicate important ideas, anything goes...
> But that's not a problem I have or need to have solved.

Sometimes it's hard to be aware of problems that exist. The fact that we have to interact with a thermostat on a regular basis is a problem. To save energy and reduce the need for us to remember to interact with the device, it might be nice for software to figure out when we leave or enter our homes (perhaps via GPS on our phones, or by some other detection mechanism) and control the device automatically. I am almost positive that your thermostat doesn't do this.
Happy users / customers
Consider these two statements:

What you would do for your closest friends, you should do for everyone.

What you wouldn't do to your closest friends, you shouldn't do to anyone.

Your post explains why the first doesn't work, but that has no bearing only the second.

I may not feel as strongly for random strangers as I do for my closest friends, but I still wouldn't kill or torture or otherwise dehumanize them.
The fact that someone is comfortable saying "all of my friends haven't used math in their successful careers, therefore math isn't useful and shouldn't be stressed and tested" is the exact reason that math should be stressed and tested.

This is hindsight bias. Knowing math helps cure you of the affliction of hindsight bias. The fact is, you don't know what career a person will end up choosing, and math is important (as is art, music, philosophy, chemistry, physics) in a subset of them. Therefore, if you want ANYONE to be able to do the math for you later on, you need to expose everyone to it to find the future mathematicians.

Not everyone grows up to be a writer, but we all read Shakespeare. Is that a waste of time? Only in hindsight.

And maybe, just maybe, this guy isn't all that smart and the test is valid. But of course, the article doesn't address that, as it's more interesting to write about anecdotal evidence and drama for the innumerate audience.
I really like this idea. The only suggestion I can make is to hire a really good designer to work on this because everything sort of looks all over the shop. To be a vanity page it really needs a solid level of polish on the visual side of things.

Their inventory went from $618M to $943M to $1,372M in Q1/Q2/Q3 2011 (while sticking around the $650M mark the two quarters prior), so it is entirely possible that they did grossly overestimate demand.

Maybe each of their CEOs placed Playbooks orders without the other knowing?
Lots of large VCs will invest as little as $100K to both get in for the next round as well as provide the team with resources they may need that are non-monetary, some will even take on advisory roles.

Investing isn't about the amount at the seed stage. An investor at the seed stage gets a whole lot more equity for their buck earlier on, so they should provide value over that of what the money will get you.
It also assumes that liquid water and an oxygen atmosphere are prerequisites for life. Extremophiles living on our own planet prove that this is not so.

Maybe this is splitting hairs, but we have evidence that life can exist in such extreme condition. We have no evidence that life can arise under those conditions. I think it's perfectly plausible that it's path-dependent: life needs the friendlier conditions to first develop; once it's up and running with a means of evolving, it's able to acclimatize gradually to the extremes.

If I'm right, then it's still correct to exclude worlds that could never have had the "correct" conditions.

No discussion on this topic is complete without George Orwell's "Politics and the English Language" essay[1]. It shiws this isn't a recent issue, and is systemic throughout the English world.

Everybody who wants to communicate well should read this regularly. It is far easier to write abstractly than it is to write concretely, so people who aren't striving to be concrete will trend towards abstraction.
