The point is that nobody knows if it's reproducible, because nobody's attempting to reproduce it.
Yeah, that was kind of the intention. Our kit was designed to be as easy as possible. It just has two motors, a sonar sensor, three IR sensors (for line detection) and a buzzer. The book that I wrote has to take an approach that makes it accessible to kids with no programming experience, but if you're familiar with C++, you'll be kicking ass in no time.

This is the exact sort of setup that I started with (professional engineer of 15 years). Two years ago when we started the program, we built it off of an Arduino and some Pololu kits. It was a great kit, but ended up costing about $150. After the success of our program in the schools, we spent the last year developing a custom PCB that has everything all built in. It has an ATmega328 chip, motor controllers, and sensors all pre-soldered on one board. It's still Arduino programming, but on our custom device. That got our manufacturing costs down to less than $50/kit and lets us sell the whole package to schools for about $100 per kid.

Now the hardest part, as I mentioned, is figuring out manufacturing at scale so that we can crank out thousands of these little suckers.

This was such a ludicrous decision. I've heard through the grapevine, though, that the council were concerned that if Google build residential housing in North Bayshore (or really anywhere in Mountain View) that they would end up being a large voting block that would control the entirety of local politics. If this was the justification, which I could certainly believe, they should have just said so... not give Intuit the building rights with no additional comment period. Intuit's plan, of course, only includes commercial development, which will make local traffic even worse. But hey, it doesn't cost the city of MOuntain View anything since most of the affected roads are state highways, and the town will collect millions in property taxes.

In Sweden where i live, a TV station that would repeatably broadcast illegal ads would loose their license. They would not be allowed to use the radio frequencies, and would loose millions from such outcome. When government agency that deal with TV broadcast makes a decision, or the consumer protection agency (a other government branch), they do listen.

Almost a decade ago, ads about subscription services went through a major change. The government dislike how "free" was used in services where all the costs was hidden in the fine print. As such, all ads related to subscriptions was changed so the the total price must be very explicit in the ad. The TV, news papers and street advertisement immediately changed as a result, mostly by stopping having advertisement for such services. They were afterward put back once marketing firms learned how to stay compliant with the decision.

Even further back in history there was a ruling against advertisement that targeted children, where there was one particular channel that went a bit further than everyone else. After the ruling, they stopped.

Now, one could assume that the sword is only dangling above the TV networks and the news papers are running wild with scamming advertisement. Except that I can find rulings (by the consumer protection agency) that target advertisement in print. A ruling in 2003 made a decision against a home catalog, ordering the company to stop printing a style of advertisement (about weight control) or face a fine of $40000 per issue.

Sweden don't have much general classified ads in newspapers, so I guess that might answer why I don't see so many shady versions. Jobs ads are done through the government job agency, and selling things through newspapers tend to be quite expensive so its almost exclusively about cars, boats or houses. Criminals tend to target cheap alternatives so that a failed attempt has less of a sunk cost, which means those who has no vetting process and minimal investment.

I spotted this in August 2014 and reported it via Automattic's responsible disclosure process (bug number #25376). They acknowledged it quite quickly and patched the hosted Wordpress.com accounts within a few weeks, and said they'd submitted a report for it to be fixed upstream, but then went silent and didn't respond to any more requests for updates. A year and a half later they awarded a $100 bug bounty with no other information. I still don't know if it's been patched in the open source Wordpress release.

My empirical experience is that programmers err too much on the side of doing things right. Most code has a relatively short lifetime; a lot of code simply won't be maintained much, because the first version is used to test a business assumption that often turns out to be false. Stability and maintainability are useful, but rarely as useful as being fast to market.

I don't think it's recruiters - hiring managers want someone who can "hit the ground running" so look for an exact match between the technology involved in their current project and the experience of an applicant.

And so the high price works exactly as intended. Microsoft KNOWS that this isn't ready for prime-time, so they put this price tag on it to make sure that it isn't buyed by someone just enthusiastic who is then dismayed when it is "not ready for prime-time" (as advertised!). They've stated multiple times that this is the reason for the price tag.
I boggled at a map of big cities which included Bradford but not Edinburgh; I think they're counting https://en.wikipedia.org/wiki/West_Yorkshire_Urban_Area as "Bradford". Of course a built-up area doesn't have a unitary urban government, which can result in planning anomalies.
I have tried both, but then do not offer the live interactivity that is possible when running off a desktop Lisp implementation. I guess this is so because we are not running a lisp image on the mobile device.

That's the reason why theory should be backed by hard evidence or a product that can be experienced. Without this, a theory of any sort whether it turns out to be right or if it is pure bullshit should not be given undue credit.
I don't personally consider that to be abuse because welfare is set at such a low level that I don't begrudge anyone who is completely (or largely) reliant upon it.

Abuse, to me, would be a wealthy person claiming benefits when they don't need them.

To elaborate a little - let's imagine welfare gives ~6000GBP a year equivalent, and any job this person can hope to get gives ~10000GBP a year equivalent.

I think if we want them to work, then they should be offered more by employers, not less in welfare. Essentially, giving them negotiating power, rather than saying 'work for BigMegaCorp for $5 an hour or starve'.
80/20 rule maybe... It's easy to have great ideas and even deliver on most of the idea ... But to actually make it great that final 20 percent is really hard and easy to mess up during the ebb and flow of product development...
> A lot of the time those same students are doing the bulk of the legwork for those findings then attributed to a professor, who is under greater pressure to advance (not confirm) science, who may or may not have even participated heavily in the grunt work of that research. The professor then punishes the work under his/her name, with no credit to the work of the students.

It's important to note that though this seems to happen in all fields, it is far less common in some. I rarely hear of such things in astronomy; it does happen, but more often I hear about faculty explicitly working to ensure they can protect projects for their students so their students can get the credit deserved for doing the project. I hear of professors appropriating student research in biology and chemistry more frequently, however.

The occurrences of professors taking and publishing student research is certainly a problem, is unethical, and should be stopped. But the way in which it is usually discussed ("in science") implies that it's a systemic issue across all science, which (from my experience) isn't true. This topic of credit and attribution for research deserves more nuanced discussion and fewer blanket statements.

Edit: Spelling, wording clarification.
> Whether this price is appropriate depends on your confidence in the forecasts and their respective probabilities.

Did I miss something or did the authors not mention a discount rate, or Weighted Average Cost of Capital (WACC)? Unless I'm wrong, a discount factor is needed to calculate the present value, regardless of using a probability-weighted DCF or a simple DCF model.

If true, then without more information on the WACC, the price they state does not only depend on our confidence in the forecasts and their respective probabilities.

Weirdly, everybody whines about the different quoting mechanisms and the use of upvar and uplevel in TCL. Coming from scheme, it's a breath of fresh air: Macros are no longer a special class! everything is unified! Sure, you lose some abstraction power with the quoting, but that's AWESOME!

And if you're wondering why lisp didn't do this, it used to, in the form of fexprs. Although there was never any equivalent of uplevel, AFAIK. Some lisps, like newlisp (which thinks we'll LOVE solving the funarg problem again) and picolisp (which also has a version of uplevel, but apparently thinks that alists are an acceptable replacement for hashmaps and other data structures, so fuck that noise), actually still have this, but it lost favor in the mainstream, partly due to the Wand paper, which proved that it makes many common compiler optimizations impossible.

2. Understanding which problems to work on (Prior to grad school I spent over a year on a problem, when I published a solution I discovered that there was very little interest. I want to build things people use.).

3. Developing better research methods (How to approach and understand a problem. How to think about solutions and measure them.).

4. Honest, critical, and in-depth feedback on all of the above.

What concerns me, as somebody who has absolutely zero interest in internet connected thermostats or fridges or whatever, is that as IoT devices become more and more ubiquitous, I'll probably still end up with some kind of quasi-surveillance garbage in my house.

Due to smart phones, computers and tablets, I already have all my internet habits being recorded, and half a dozen cameras and microphones all over the house.

Whats just as concerning is how many quasi-legitimate service providers, for reasons of people desperately trying to secure themselves from bad actors, end up finding technical solutions that are indistinguishable from malware and other kinds of network attacks/exfil techniques.
