I think teaching fundamental mathematics to programmers using ITS (Intelligent Tutoring System) technology is a very promising idea. For example, an ITS that is capable of doing step-by-step elementary algebra equation solving would be able to teach this subject, and it would also be able to provide instant feedback which is much more detailed than a human would typically provide.

I have been working on a step-by-step elementary algebra equation solver for a few years now, and here is an example of what I have working so far:

If you are interested in discussing the possibility of teaching programmers fundamental mathematics using technology like this, feel free to contact me (my email address is in my profile).
I really would like to hear what would these people say now.

I bet in: "When the facts change, I change my mind. Don't you, sir?"

There is no such tech. If you think there is post a link to it.

At best there is current research (not actually a product yet) to identify the chicks while still in the egg, and I see absolutely no difference between killing them in the egg or out of it.

Just kill them painlessly (i.e. extremely quickly) and move on.
Sell you stuff? It isn't speaking to you on its own. You're asking it to do this for you and then it does.
> If someone came up with a better search engine, Google would just buy it or hire the principals before they did.

Not really. The people with the better search engine might prefer to be 'the next Google' instead, and if they're not public yet its easy to not be bought. Just say no (even the VC's might prefer this as it could be a bigger later payout). If it was that easy to just buy anyone you wanted, Google would've owned Facebook quite awhile ago.
I personally loved "The Bogleheads' Guide to Investing"

The Boglehead philosophy gives one a sense of humility in a world that's driven by hype and market timing. If we are to believe that financial markets are more-or-less efficient, then it stands to reason that you won't be able to consistently pick stocks that perform better than market averages. It teaches you how to grow your wealth in the long run by investing in low fee, unmanaged index funds. It also talks about how to invest in a tax-efficient manner and how to spend/invest appropriate amounts of your income. All around its the best primer to finance that I have read.

One of his two nameservers, ns2.missoulaweb.com (66.235.178.171), is non-responsive. The other one works but it's listed second. No round-robin. That can slow down the DNS lookup, as the first listed nameserver will likely be tried first, adding to the "slowness" of a website.

Dead nameservers are relatively rare among sites that get posted to HN, since many are high traffic and use CDNs (that rely on DNS kludges). But it is still a regular occurrence. No one ever talks about it. But it's one of the DNS kludges that's continually slowing things down behind the scenes.

There is that term "link rot" for URL's that do not work anymore. And "bit rot" for source code. I propose a new one: "NS rot".

Well the majority of good software jobs are going to be geographically limited as well, unless you have the skillset and experience to break into remote work.
Not the best example, but at about 5 minutes in you can see how I construct palette entries and how those entries automatically get applied to the screen without recomputing the underlying voxels. I construct two dimensional palettes actually, with just a few entries and it blends between those entries. This allows cycling along two axes of the palette - i.e. one axis can be used to represent shading by amount of light, and the other can represent cycling over time or variations in the underlying pattern. https://youtu.be/X7MYf01X1Y4?t=5m

If you are using a shader, it takes only one texture lookup (into your palette) to do this, so it is extremely cheap.

I am saddened that we live in a time where people surreptitiously photograph others in public without any thought to ethics. I know it's legal and people should have no expectation of privacy in public but it's tragic to see this gradual erosion of common-courtesy privacy.
I feel much more comfortable having conversations with collaborators in an office where I know my conversation isn't bothering anyone else.
Entering the US requires an initial contact address on the arrival form. Once in, you can then go stay whereever you like, without any further address registration update requirement.

This is as opposed to Russia and China, where foreigners are required to notify the government of every address they ever stay at.
Thanks for reporting this. Someone else noticed it on a nexus tablet as well. I'm looking into getting this fixed.
I seriously doubt you will really get the info you need from tossing this question out there on this forum.

The people who are for the UBI tend to see the world differently from the people who are against it. They look at the same data and draw different conclusions.

I have written a few anti UBI pieces. I have had someone tell me "The data for when they have tried it is all positive" or whatever. But, then they link me to trials that I find unconvincing. If you have a UBI trial that involves just one small town and there is intent from the start that it will have a limited duration, you will get different human behavior than if you genuinely try to implement some kind of guaranteed security.

Every historical attempt that I am personally familiar with where they tried to promise universal security has failed. These historical attempts were not called Universal Basic Income. They had names like communism -- the idea being we would all live communally and the community came first and took care of everyone. The result in every real world trial I know of for promising some kind of baseline security to all members of the group is that too many people decide to just be freeloaders and not do fuck all, since they won't starve if they don't do a damn thing.

I have blogged about this from an anti-UBI perspective. It has not been well received. I am not sure I am going to bother to keep blogging about it because I am not convinced it matters. I am skeptical that it will ever actually happen and, if it does, it will likely fail in short order, like all previous attempts.

The only question is whether the failure will cause so much widespread harm that I need to care or not. It might make more sense for me to just keep on keeping on with trying to solve my own substantial personal problems that most people don't give a fuck about, while continuing to light one small candle where I can for helping others currently suffering due to the issues out in the world today.

You might find better answers by either searching Hacker News for previous discussions of the UBI or searching the web. A lot of people are for it. You can easily find their arguments in various places and that might be more helpful than what you are likely to get for answers here.

Best of luck.
Did it work? If not, can you hit ESC and still save the option?

(None of my old TPs have this, so I can't check.)
The corollary is that you should reorg your dev teams to shape the product you want to build.
Suggestions for a more rigorous treatment?
There was a link to a presentation by Mark Ferrari (the artist) which surfaced on HN within the past couple months which showed these pictures. These aren't just animated, but for some of these pictures, you can also animate the transition from day to night and back with the palette.

They were apparently made for a screensaver which would display daylight or nighttime according to the computer's clock.
>How would Americans feel if China invaded California, slaughtering hundreds of thousands of civilians in the process of occupying the land by force, completely destroying the local culture and economy, raping and killing more or less without consequence, and then never left?

Your analogy is incomplete because you left out the part where this fictional America conquered all of its neighbors and engaged in mass rape and murder and was in the process of attempting global domination in tandem with the Nazis. And if you're referring to the nuclear bombings, then perhaps you aren't aware that the US had encountered nothing but total violent resistance from Japanese populations that they had occupied. An invasion of the mainland would have been an absolute blood bath, and Japan refused to surrender.
Who is this book supposed to be for? Given the heavy emphasis on formalism (theorem, proof, theorem, proof, theorem, proof), and the lack of a single example that actually computes a number, I hazard a guess that this book is not for people who actually want to apply statistics to real problems.

A while back I had to teach myself Fisher matrices and the Cramér–Rao bound to solve a problem I was working on. I quickly found that 90% of statistics textbooks and lecture notes on this subject are completely useless for people like me who want to arrive at a number, not some abstract expression involving angle brackets or measures or E[...] or whatever.

The Wikipedia article on Fisher information [0] is one such example of a resource that is full of useless formal crap that crowds out an explanation for real people about how to use this statistical tool. This book appears to be of the same ilk. (Also, this book apparently does not discuss the Cramér–Rao bound. Ironic given the book's title.)

If anyone is curious, the single best explanation of the Fisher matrix and the Cramér–Rao bound that I have found is tucked away in an appendix of the Report of the Dark Energy Task Force [1]. In one page they manage to concisely and clearly explain where the Fisher matrix comes from, how to compute it, and how to apply the Cramér–Rao bound.

Heavily impacted engineering program at one of the top University of California campuses.

It spoke for the grading structure of the homework and did not apply to all courses.

Exams and projects were graded much more rigorously and there was a similar drop out/fail rate as you describe.

Not all engineering courses required homework for a grade. Often homework was only worth 5%, exams and projects the remainder. However, weekly problem sets easily consumed 10-15hrs per course, 3-4 courses per quarter.

Professors left it to the student to prove their understanding of coursework through exams. I often suspected due to the high rate of plagerism on homework (copying peers or access to solution guides).

Edit: don't get me wrong, I never had free time as a student. Every free moment outside of class was consumed by studying, working, eating or sleeping. I occasionally skipped lectures to buy free time.

It all came down to risk assessment which is a valuable skill to be learned for industry.

Time management I learned in school has paid off tremendously in my career and is something I seek more than a minimum GPA threshold in my interns and Jr. Eng's.

> One of the nice things about the large-small split is that it satisfies all parties, ...

Unfortunately not. R7RS-small introduced some incompatibilities with R6RS that caused some R6RS fans (yes, they exist) to dissent. One was samth, as I recall, but I can't remember the names of any of the other outspoken critics of R7RS. If the mailing lists hadn't disappeared, I'd probably be able to find the threads for you. They made some good points.

Personally, my gripes with the R7RS-small are pretty minor, and overall I think it's good and I welcome it whole-heartedly. The modules and the records were sorely needed for decades. They were slotted for R5RS, but back then the RnRS was ratified by full consensus rather than majority vote, and some people simply refused to compromise. This is why R5RS took almost 10 years when its predecessors only took a handful of years. (In retrospect, I wish they'd made them an appendix in R5RS, like what they did for macros in R4RS, but it's far too late for that now...).

Hairdressers and nurses are also licensed by the state. I don't think it's malicious.

Maybe the broader question is, why are we vetting so many jobs through state licensing?

"A 2013 study found that 25% of today’s workforce is in an occupation licensed by a state entity, up from just 5% in 1950."

For me, as a native English speaker, 'impoverished' connotes a significant difference in standard of living relative to what I'm used to. So I would agree with you here - one would have to take the relative purchasing power of the wages into account before characterizing an entire country as impoverished.

So excited about this project.
The other way to fix this is to allow liability for labor law and health code violations to pass all the way up the contracting chain. The only reason Tesla doesn't care is they can insulate themselves from liability via the outsourcing relationship; were Tesla liable for law violations, they'd make sure everything was aboveboard. viz labor board ruling McDonalds is jointly liable for wage violations of franchisees. McDonalds will have a newfound interesting in making sure every person working at McDonalds is correctly paid. [1]

I pointed this very theory out elsewhere.

Tim Cook has been a master of logistics for a LONG time now. I think he is well aware that the risk of an apple car, and the cost of doing it well are far out of line with the reward. Apple isn't interested in commodity items, and thats where all the profit in vehicles resides.

Apple does have a full ecosystem of technology that you would need to "own" the dashboard of a car. Entertainment (music and something that looks like radio) and Maps for the front seat; video, books and games for the back (upfront too if it is self driving).

Is it possible or likely that apple is building MORE into this car experience, it sure is. If your going to put that much processing power into entertainment, there is probably more than enough to spare to help with other aspects of self driving. Just let the people who are going to do that tap into it.
Google just released a YouTube music player to compete with Apple and Rdio. Coincidence?
What's the appliance? Most current consumer routers come with a backdoor called TR-069[0] that allows the ISP to provision and update the device. Recently other appliances than routers have started using the same protocol.

The session is initiated from the client, but if you can MITM it or compromise the provisioning server all bets are obviously off.

I have mixed feelings about TR-069, but don't see how devices can stay current without something like it.

I have a refrain I like to repeat to myself sometimes, which goes roughly like: in the land of the blind, the one-eyed man is king.

It's true that the interviews can be pretty retarded. Most of our roles don't require knowing half the complex stuff they ask to weed people out. If you're just out of college that stuff is reasonable to ask [1], but otherwise as a hiring manager you should ask what you're looking for. For example, if I'm looking for someone who a) doesn't lie about their experience b) has experience in some of the technologies I need a project completed with or ongoing support for on day 1 c) has the ability to learn technologies I'll need help with on day 180, then I'll ask about a project that was listed on the CV, stopping to ask for more detail about how something works. Then I might present a scenario or problem that's theoretical (or really happened) and have the candidate walk through it.

That was when I was a hiring manager. I didn't weed out good people by asking them dumb questions about how many marbles would fit from here to the moon, or about the different types of O notation. Of course, this is specific to the roles I was hiring for (DevOps).

When I was on the flipside, I was weeded out by overachieving mid 20-somethings who really relished putting me on the hot seat. It felt not dissimilar to a bad date sometimes.

I consider it a 'competitive advantage' that the latter style of interviewing is so commonplace, because it's so off-base. It doesn't make me as frustrated anymore, probably because I'm old and cynical, and a lot more independent now. My thinking now is 'how can I use this to get a leg up on the competition' whether that means learning some cursory rote algorithms stuff if I'm interviewing, or just knowing how to ask the RIGHT questions to get the good candidates (something I feel pretty comfortable about) if I'm the interviewer.

[1] I think it's reasonable to ask questions of a college grad that he would have learned in a hard-core comp-sci class for the same reason I'd ask in-depth questions about the projects in the last role: because it's the freshest thing in their minds and they 'should' probably it. Please don't bother us old guys with comp-sci fundamentals. Unix and TCP/IP fundamentals, on the other hand ...

Trust me, I know exactly what you mean.

I am more concerned with more specific questions pertaining to UBI. For instance, "Does UBI fix _____ compared to means-tested welfare?" or, most likely what my article will be about, "Do we need UBI because robots will take all of our jobs?"

I believe that those who favor UBI can still appreciate that a particular argument is invalid-- although the idea as a whole may not be. Of course in order to do this, the article must fairly represent both sides.

But yeah... I'm not trying to convert people to be against UBI. That would be hopeless.
That's obvious though, isn't it? People are going to gravitate towards adopting the language with highest economic and social capital (presumably why English took over French as an international language?).
> Monopolies are not illegal. Abusing a monopoly position to unfairly crush the competition is.

That sounds nice and fairly reasonable. Unfortunately it's not necessarily true. In U.S. v. Alcoa [0], the Supreme Court [1] held that Alcoa's dominance in the aluminum market was illegal, despite the fact that their dominance was attained simply by regularly adding new industrial capacity and executing their business efficiently.

[1] actually the Second Circuit ruled on the Supreme Court's behalf; an interesting story for another day.
Is 4 lots?
With many games the copyright comes to an end and, when that happens, one company no longer has the entire market for that game. Consequently anyone else can make the game, to undercut the original price competitively. This happened about a decade ago with 'Connect 4', originally a premium product by MB games, nowadays anyone can make it but they have to call it 'Four in a Row' or something like that. Needless to say the clones and the updated 'Connect 4' are rubbish compared to the 1980's vintage version.

I don't know what the copyright situation is with Scrabble, however, there's bound to be some reasons like what has gone on with 'Connect 4' meaning the product is degraded.

I believe the GP comment wasn't too far off. This article from last year says the Germans have done promising research and intend to have a working prototype this year, which sexes (technical term) chicks at just three days after inoculation.

http://m.thepoultrysite.com/news/34741

I also understand there is no tech used to identify the sex of chicks at a young enough age. It's a highly specialized skill (chicken sexing) that takes lots of training. I think it's even specialized between different types of poultry.
You're right. I'd underestimated crossing times, though prevailing winds also cut time to as little as 43 hours eastward. From Wikipedia's page on the Hindenberg (unattributed):

"The ten westward trips that season took 53 to 78 hours and eastward took 43 to 61 hours."

Given that high-speed land-based rail would be an option, the ferry-to-rail option seems a strong contender, actually.

Remember: the whole concept of moving any significant distance at a rate of more than a few miles an hour is quite modern.
This is scarily accurate for Japanese companies.
Learning assembly was probably the biggest thing that made computers click in my head. Since then, I've always thought that learning assembly as your first programming language would be a great place to start. Of course, I'm sure this doesn't apply to everyone.

In CS you're usually started off with something like C, Java, or Python. But those languages are so HUGE (in comparison) that it can be really overwhelming. Meanwhile, with assembly, you have far fewer items in your toolbox and you have no abstractions between what you write and what's being executed.

After googling, I found emu8086 [0], which I think is what I used to debug the tiny apps I was writing. It was great! You could step back and forward in time, and you could inspect every detail.

It sounds like an informal description of the idea of government regulation of natural monopolies. Such regulation is very popular for things like municipal water and electricity infrastructure, but I haven't seen a good argument for why the Internet search engine market would be a natural monopoly.

Roughly speaking Brett Glass is to WISPs as Richard Stallman is to the modern open source ecosystem.

Maybe did some important things back in the day but for the past 10 years the situation has largely shifted from idealism to pragmatism.

Yes, there are a lot of WISPs that are run basically as a hobby.
There are also a lot of WISPs (and more broadly xISPs) that do things professionally.
