I do think I know more about technology than management does. Management knows more than I do about how to run a business. Neither one of us has the entire picture. We have to inform each other as well as we can, so that our business decisions reflect good judgment across all of our areas of expertise.

Sometimes we have to explain things to each other, and sometimes those explanations need to go into depth. Some of my best moments in business have been when someone went to the whiteboard and effectively taught a little class.

There is a reason why management is asking for it.

The reason might be one of these two:

1. Management knows what they're talking about: there's some valid business reason why the information needs to be in the requested form; and the tech guy just isn't aware of that reason.

2. Management thinks they know what they want, but their request reflects an incomplete understanding as to what technical solutions are possible, and which one would really best serve the business.

I encounter both situations regularly. Sometimes I investigate and find out that management really does have good reasons. Sometimes I conclude that I'm dealing with case #2 above. It's not that I think management is stupid; it's just that their expertise is in a different area from mine. I often try to educate, depending on how important I think the issue is. Fairly often, my effort succeeds: managers generally want to do right for the business; they understand that the tech guy knows things and is worth listening to; and sometimes they agree that my proposal is better.

However, of course the effort doesn't always succeed. Unless you're writing software on your own without having to please clients or management (e.g. as a hobby, or in an academic setting), it's just a part of life as a paid tech guy that you sometimes have to implement decisions which were made without the benefit of as much tech expertise as you have yourself.

The article says that they're using a genetic algorithm. I'm no expert at AI, but my understanding is that an ordinary expert system doesn't use a genetic algorithm; an expert system just involves percolating propositions through a bunch of human-specified if/then statements.

I'd hazard a guess that the system described here is using the human-specified rules as part of the fitness function for the genetic algorithm. That's one way a system could use human-specified rules, but I think it's different from how an ordinary expert system uses them.

If you can call this an "expert system", then at a minimum, it looks like it's pushing the boundaries of the definition of "expert system".

True, but the null hypothesis is that men and women are equally capable at CS, however you measure that. Likewise with whites and blacks. Unless there's data to indicate otherwise, I'm assuming that knowing somebody's race or sex doesn't tell you anything about how likely they are to be good at CS.

The numbers might give the impression that Google and Yahoo are unfairly discriminating against blacks and women. To determine whether that's the case, I think you need to know two things:

--Among Google and Yahoo employees, what percentage are black? What percentage are women?
--Among CS graduates, what percentage are black? What percentage are women?

(I'm simplifying here by assuming that every hire at Google and Yahoo is a CS graduate.)

If the two sets of numbers differ significantly, then it could indicate discriminatory hiring practices. If the numbers are the same, then it would seem to indicate that Google and Yahoo are evenhandedly hiring from the pool of available candidates, and that the cause of the inequality is further upstream.

I don't think anyone claims that open-source software won't ever have security issues. The claim is that the open-source model tends to find and correct the flaws more effectively than the closed-source model, and that the soundness of the resulting product tends to be better on average.

One case does not disprove that. The key words there are "tends" and "on average".

There have been various alternative calendars proposed, and some of them have the property that there's a special day in the yearly calendar which doesn't count as part of the regular seven-day-per-week cycle (such as the "month zero" proposed here).

A significant objection is that some religions require that every seventh day be kept as a holy day. If the calendar contains a day which isn't part of the regular week, then there are sometimes more than seven days between one weekly holy day and the next.

It's not a consideration for me personally. However, I'm sure that this feature would lead to significant resistance to the adoption of such a calendar.

I dropped out of high school in 1983. I was being heavily harassed for being openly gay. I could take it no longer.

I took my GED and passed it easily on the first try. Then I worked my ass off, largely financed my own education, and eventually got a PhD from one of the Ivy League universities. Now I have a successful career.

If the option of the GED hadn't been there for me, I would have been at a dead end.

Nestle's GPS Tracking Candy Campaign 172

colinneagle writes "In a cool yet creepy marketing campaign, Nestle plans to stalk UK consumers. The company kicked off a unique promotion called 'We will find you' that involves GPS trackers embedded in chocolate bars. When a winning consumer opens the wrapper, it activates and notifies the prize team who promises to track them down within 24 hours to deliver a check for £10,000. A Nestle spokesman added that 'inside their wrappers, the GPS-enabled bars looked just like normal chocolate bars.'"

35 Years Later, Voyager 1 Is Heading For the Stars 226

Posted by Soulskill
from the watch-out-for-black-holes dept.
DevotedSkeptic writes with news that today is the 35th anniversary of Voyager 1's launch. (Voyager 2 reached the same anniversary on August 20.) Voyager 1 is roughly 18 billion kilometers from the sun, slowly but steadily pushing through the heliosheath and toward interstellar space. From the article: "Perhaps no one on Earth will relish the moment more than 76-year-old Ed Stone, who has toiled on the project from the start. 'We're anxious to get outside and find what's out there,' he said. When NASA's Voyager 1 and Voyager 2 first rocketed out of Earth's grip in 1977, no one knew how long they would live. Now, they are the longest-operating spacecraft in history and the most distant, at billions of miles from Earth but in different directions. ... Voyager 1 is in uncharted celestial territory. One thing is clear: The boundary that separates the solar system and interstellar space is near, but it could take days, months or years to cross that milestone. ... These days, a handful of engineers diligently listen for the Voyagers from a satellite campus not far from the NASA Jet Propulsion Laboratory, which built the spacecraft. The control room, with its cubicles and carpeting, could be mistaken for an insurance office if not for a blue sign overhead that reads 'Mission Controller' and a warning on a computer: 'Voyager mission critical hardware. Please do not touch!' There are no full-time scientists left on the mission, but 20 part-timers analyze the data streamed back. Since the spacecraft are so far out, it takes 17 hours for a radio signal from Voyager 1 to travel to Earth. For Voyager 2, it takes about 13 hours."

In the 1990s, I wanted to get into developing GUI apps for Linux. The single biggest reason why I gave up on it was that the Linux GUI effort fractured into KDE and Gnome camps.

At the time, I figured that one of the two would win out over the other. There was no telling which might win, and I was reluctant to back what might be the losing horse. This was a serious demotivator. Of course, 15 years later, we've ended up with the worst of both worlds: many Linux installations take up the disk space for both, and we've got two unharmonized APIs continuing to fight for a following.

With MacOS, there is no question what API you should use. Apple offers a very clear path. For that reason, I feel more confident developing for that platform.

More Plans For UK Internet Snooping Bill Revealed In Queen's Speech 114

From their article: "It's unclear if those 'strict safeguards' mean that a warrant, for example, would be needed before spooks could access such data.

Sorry, but this is bull. Your statement that "voice recognition is at its limits phonetically" is just wrong. I work in the voice recognition industry, and in the past five years, I've seen the recognition error rate markedly and measurably go down, and this trend is continuing.

There are actually two kinds of models involved in voice recognition:

1) the acoustic model (which has to do with looking at a sequence of time slices of the acoustic signal and working out what sequence of phonemes could most likely have given rise to it). You say that voice recognition is at its limits phonetically, but these models are actually getting better over time with larger sets of training data, and the improved models measurably result in a lowered word error rate.

2) the language model (which has to do with specifying which words exist, and in what order they are most likely to occur). These language models can be very simple, as in the case of a yes/no question in a phone-based app (your model might accept "yes" and "yes ma'am", but not any arbitrary English utterance); or they can be very large, as in the case of a general-purpose dictation application.

In conjunction with the recognizer, what these two models give you is a raw string of recognized words. What sort of processing you do on that string is a separate question. There are obviously all sorts of things you can do with the string. The parsing and processing techniques are getting more sophisticated, and are getting integrated with other systems in interesting ways. This is largely a separate question from the accuracy of the string itself, which is the output of the recognizer (I say "largely" because your application might activate a different language model based on the current context, which does affect recognition accuracy).
