Ooooh! Story time!

In 2005 and 2006, I worked in a biology lab that worked on similar things as Dr. Rind's lab. I don't recall if we collaborated directly, but there was definitely a lot of overlap and I think we shared papers back and forth.

When I arrived, the biologists had rigged up a pretty amazing setup. They had a system that was measuring locust wing-muscle activations, and feeding that in through a joystick port to Descent (yes, the game). This was a more closed-loop version of the "watching Star Wars" stuff talked about in the article. The system had a couple flaws, though. The biggest being that it was being projected onto a hemispherical dome that the locust sat in, but the scene wasn't perspective-corrected for the dome. It still worked, sort of though; you could watch the insect successfully navigate around obstacles, but it was pretty crude.

Over the two summers (I was a student at the time), I did the majority of development on a more controlled and perspective-corrected system for them. It included a simple scripting language (since I had, you know, just finished my compilers course) for the scientists to describe specific scenes to project for the insect, instead of just using the pre-made Descent levels. It did some really cool projecting mapping, such that, given a known position of the insect's eyes relative to the hemispherical screen, we could project perspective-correct 3D imagery. It had a USB device for more predictable input than the joystick port. And it included time synchronization signals that could be fed back into the muscle-impulse-capture hardware to more easily correlate events in the 3D scene with muscle events.

I haven't kept in touch with the lab much, but last I heard they're still using a derivative of the system I helped build there. The USB controller died at some point and was replaced with an Arduino, and I think some new summer students have tweaked this and that, but best I can tell the system is still mostly alive (even if it's been through a Ship of Theseus transformation).

The results were really cool too! You could watch the insect successfully navigate around obstacles by changing the timing differential between wingbeats!

Anyway... I'm happy to chat about this more if anyone's interested, with the caveat that I'm not a biologist and was way more focused on the EE and CS aspects of doing the measurements. I do recall that there was a particular neuron that was being investigated (the Descending Contralateral Motion Detector - DCMD) in our lab, but don't know a whole lot more than that.

Why not find a small real world coding test from your actual day to day work? I’ve found testing with riddles finds people who are good a riddles. You find what you look for.
Even Stalin-era test pilots feared a charge of sabotage if something went wrong on a flight. Which was particularly terrifying when Stalin would give chief designers an arbitrary deadline of one or two years to build a prototype. It had to work first time or a lot of people were going to the gulag.

No-one was safe from Stalin's vengeance, except apparently General Tito of Yugoslavia who survived many of his assassination attempts and allegedly returned the favour successfully.
Perhaps it's besides the point, but core osx is open source as Darwin and XNU, and I don't see much value in them. NT hybrid kernel is extremely well designed, and there is an ecosystem built around it. It is extremely unlikely anyone at Microsoft will find anything aiding in Office 98 compatability online...

Seems like AR is a lot more approachable than VR in that you don't have to strap on so much gear to immerse yourself into a Virtual Based / Enhanced reality. Even Snap seems to be invested in AR if you think about it, how many snaps don't feature some augmented visuals? If people go crazy over that to the point that Facebook, and even iOS steals that type of AR functionality, there must be more to AR than meets the eye.

To a computer geek it may not seem impressive now, but to the average person it casually sneaks up into their everyday life.
I’d just say fizzbuzz and a good conversation would be fine.
If you don't pay, it destroys your credit rating, which in many areas means you won't be able to rent a place to live from anything but a private party. I believe they could also potentially get an injunction against you and garnish your wages, but I'm not certain about that. Your college also may withhold your transcript, which can impact some employers who require that.

Lots of ways they can make your life just as miserable for not paying.

"Typically"?
To be honest, it was a mismatch of expectations we have based on prior knowledge of a medium, and what the game had actually to offer. Just like you know that after being 45 min into a movie you're reasonably not even close to its ending, it didn't even cross my mind that what I was seeing was the game finale.

I sat down there, looking at the screen like a fool, not understanding that the game had ended. I won't deny it, I wanted to bring Lester back home, through many more adventures! :)
Why Bother Presenting as a Developer?
An engineering degree is arguably by far even more absurd in cost. Significant class loads that make working a part time job unrealistic, making you rely upon dorm and food plan costs which match that of tuiton yearly. A significant amount of dorms have living conditions that universities would argue any other commercial enterprise shouldn't be able to call 'housing'. Not even an oven to be found.
By reading strictly your sentence, I sense a definition of useful as "the way to repay a big debt".
The article is about student loan debt, and my claim is that it's the government's fault.
My link is purposefully not on topic - that's the purpose and definition of a parable.

A couple of the things. The first is that if your explanation, which is the most convenient, to explain the Flynn effect was correct we'd expect to see a decline approaching some asymptotic zero as we experienced diminishing returns from things like nutrition and education. But this is not what's happening. IQs are getting literally lower (not growing more slowly), and substantially so. 84% of people fall within the first standard deviation, which in IQ is normalized to 15 points, and we're seeing declines of multiple points that don't seem to be stopping. That's really something that I think should be extremely concerning, but socially we seem to have a bit of head-in-the-sand defense mechanism in play.

On support. I'd say my hypothesis is just about as supported as the average view in social sciences. I could certainly formulate an experiment of passable merit to confirm my biases. Of course that by no means means the hypothesis is right, but rather that the notion of scientific support in social views is something I think we should take as a default to be practically meaningless. There are so many ways to quantify and qualify various aspects of society that near any hypothesis can be proven if you play with the data enough. This paper is evidence of such:

"To date, however, research on the relationship between adherence to masculine norms and fathering has yielded mixed results, which
may be due in part to the fact that many studies use measures of masculinity that do not fully capture hegemonic masculine norms. ...we address this question and extend the literature in three key ways. First, we use a multidimensional and more comprehensive indicator of masculinity than used in prior studies... we consider whether masculine norm adherence inﬂuences fathering in different way...."

Or to put another way, 'previous research has not yielded the results we wanted to see, so we spun the data in a way such that we could get it.' It's really quite absurd.
The first bill I received for my MFA loans was for $416.

I panicked and applied for an income-based repayment plan, which, paired with my habitual underearning, lowered my payments to $96 a month.

After five years of payments, I now owe more than what I originally borrowed because my payments haven’t even scratched the principal.

Income based repayments forgives the loans and interest after 25 years.

Original principal is $44,000. $96 X 12 = $1,152 / year. 25 X 1152 = $28,800 total repaid.

So, 20 years to go...
The first killer app for AR was probably Word Lens (translating images of words in real time) and that debuted in 2010. Then Pokemon Go 6 years later. I can't think of anything else that has caught on. Seems like a really exciting paradigm, but no one has figured out anything useful to do with it.
I believe it’s generally assumed to be significantly cheaper to process in situ and only return what is actually desired. Delta-v is expensive.

In Australia, one reasonably well known business identity kept getting infringement notices from speed cameras. The car was owned by the company, and the company would never identify the driver and just paid the fine. So the driver never received the demerit points.

I believe that because of this, the fines were made significantly higher for companies that did not identify the driver.

To be fair, the "getting it down" the gravity well is easy and inexpensive, but "landing" it is a different problem.
I don't know the details, but here goes...

In the USA, government and private student loans are easily available. I have never heard of anyone who couldn't study becuase they couldn't get loans, though I'm sure it happens. I have heard of many people who accumulate huge debts for degrees that offer a low increase in potential future earnings. Like an MFA frankly.

This is mostly becuase USA student debt is a special debt that follows you for life. It cannot be discharged in bankruptcy. You can enslave yourself with a bad loan. Your soul is the collateral.

That's the absurdity the author refers to.
As to one sentence in particular in ch01s09:

"If someone has already solved a problem once, don't let pride or politics suck you into solving it a second time rather than re-using."

I'd strongly argue it's overzealous. As much as I agree "reinventing the wheel" is dangerous, tempting, and can quickly spiral to yak shaving, but Unix itself, and all the good it brought, is a prime example of "solving [a problem] a second time" after Multics.

In other words, I'd restate it in Sage Speak™: "Don't do this. Except when you need to." ;P Or, just want to have fun :P
Student loans should be dischargeable in bankruptcy after 10 years post-graduation (and not fully guaranteed past a certain amount, say $10K or $20K) -- hear me out.

The common reason student loans are NOT allowed to be dischargeable is because, in the minute after graduating and without collateral, the student can declare bankruptcy with no effect (the vast majority are not buying a house within the time it would take for their credit to repair).

This has the side effect of blunting market forces. It is the same amount of interest and same approval process to get 200K for medical school as it does for an art degree, despite market forces suggesting that the former are vastly more needed (ok, granted, there's the AMA, but that's another discussion). It doesn't matter to the bank -- after all you can just repay a little bit until you're 70 years old.

Allowing things to be dischargeable 10 years after graduation would reintroduce market forces. You want 200K for medical school (maybe we change the post-graduation length a bit to account for residency / fellowship)? Great! Almost guaranteed well-paying job out the other end.

But 150K for an expensive art school + MFA? You better be prepared to have your credit looked at under a microscope. Application rejected.

What would this mean? This would mean that schools would actually have either a) provide more value to the individual, b) charge less or c) accept much smaller classes. It would mean they would probably have to focus most of their energy on education + job placement rather than funding more school athletics and building a fancier dorm.
> I can't help but think that college admissions based solely on test scores (as done in India, Russia, maybe China?)

Russian here, this is not entirely correct. Instead of race you have region and when that region is 80-90%+ single ethnicity then a region division serves as "race-by-proxy".

You can also get a certain region overrepresented (with regards to it's total population) and by extension certain ethnicity as well.

What angers me the most about debt like this is people often take on far more debt than they need for a degree. For example, going to a university in a different country/state where they cannot get any of the scholarships intended for residents. Another one a lot of my friends have done is going to a university that is substantially more expensive for very little gain. Another common one is renting student housing when it is perfectly feasible to live at home and commute. While the debt still may be excessive, it can be substantially reduced.

Also, a specific thing for anyone working on a degree (particularly an undergrad), check out CLEP exams. Very affordable per credit hour and you don't need to spend a semester listening to a professor [1].

No. If you're editing markdown, there's a preview tab but it doesn't account for anything that's part of your jekyll template. Your app isn't running at all.
College tuiton by itself with help from federal and state aid, yes. Housing+food costs if you can't get an apartment, that matches tuiton in my state. It should be that you work a part time job to pay rent and be able to make your own food, that way you get good living conditions and don't pay back an absurd amount after college. But lots of universities around here are designed to not even have much housing around them. You have to drive and pay for a $150 a semester parking pass, which is not guaranteed to have a spot.
I think it’s an excellent example and the artificial scarcity is irrelevant to the point being made: total market value of all $substance is not constant when quantity of $substance changes.
Yeah, so what if the father is the sole income earner of his starting family and being forced to take leave (with its attendant pay cut) causes him to miss a rental payment and his family gets evicted?

This is a draconian idea. Besides, employers don't want it! If they didn't want you coming to work, they would lay you off. Otherwise they're going to look the other way. Families living on the edge will do anything to avoid this problem, including leaving the father's name off the birth certificate, if it comes to that.
> is there never minimal cost-benefit analysis?

Of course not. A huge portion of the population has essentially no understanding of finances, which is why they need to do things like call to ask why their loan balance is going up. Worse, there is a feeling of helplessness when finances seem like a mystery, hence in this case actually needing someone else to tell them to call and ask.

This is why the cries of “free market!” when, e.g., discussing caps on usurious rates at payday loan companies are missing the point. People get trapped in debt with no way and no understanding of how to get out.
Ultimately the one with the biggest pockets wins in that scenario.

A firm that has enough money to fund 300 businesses will probably have a lot less variance/cash flow problems than one that can only afford to fund 30.

Outrageous student loan debt, and the lack of means to pay for them after spending, has been an issue for at least 10 years now and has been thoroughly documented. It shouldn't be a mystery to anyone at this point, and it's baffling why people are still taking on these large debt loads for degrees and programs which don't have a snowball's chance in hell of paying off the debt in a reasonable amount of time.

My own personal experience with bad debt was my own fault, so I have a habit of blaming the person who willfully enters into debt; I opened a credit card as a young man without understanding the system, racked up huge balances, was eaten alive by interest and was forced to go into collection and settle. That effectively crushed my credit for 8 years. I did however learn a ton and was able to rebuild my credit. My children won't have to learn the hard way, unless they choose (operative word) to ignore the lessons I had to endure.

So without blaming the author for their own actions and writing it off as a "you should've known better"; Is the greater problem these days of a predatory nature by lenders, ignorance (willful or not), or a complete lack of education about an education? Or perhaps D. All of the above.

If you’re taking out a loan to pay for the degree, you’d better believe that’s the definition.
I sort of agree. I didn't quote those sections in the sense of recommending that the advice in them be followed strictly, and to the letter. Also, ESR is known to talk a bit that way - sort of overzealous, as you put it. But that is part of the fun of reading his stuff. As long as one takes it with a pinch of salt, and common sense, it is okay, and one usually gets to learn something from his writings.
Ask HN: Software Engineer career switch
Why isn’t there a company out there that offers a career switch for software engineers? Not only the amount of people who’d like to move away from coding or tech in general (burnt out, no motivation, etc.), but more importantly the increase of AI. Coding will be done by machines in a near future. Which means a lot of software engineers will be out of work. Is it too pretentious to say that problem solving in general is a valuable skill?

> The way to prevent that is to learn about these optimizations, which change often and in undocumented ways, making your code perform very differently across versions.

Not only that, your code can perform very differently across minor changes! All it takes is a single modification to start triggering cascading deoptimizations and lead to severely degraded performance. Even writing 0 instead of 0.0 (or vice versa) can change how the code is optimized and reduce performance.

I suspect it's the same thing as when buying a house. The numbers are too big and become just numbers, without a corresponding value. 10K more or less doesn't seem to matter all that much, while in other cases one might agonize over a $50 price difference.

> You were talking about equalized impact to start with, I really don't see how this is a good example.

I am _not_ talking about equalised impact i'm talking about equalised results... the OP was suggesting that speed tickets don't stop rich people from speeding, but if you loose your license it does - that is the purpose of these laws, not to try to figure out how much punishment to deal out in relation to your personal wealth, punishment is a means to an end, not an end in itself - the end being to stop you from doing something damaging to society, in this case endangering other people's lives.

Taking away licences is an equaliser in this respect, because being rich doesn't give you more points to spend.

Licenses are for individuals, if some rich person wants to pay some _other_ individual who can actually keep their license that is fine, the law won because a safer person is driving.
