There are already hotels for the homeless which provide cramped and spartan accommodations. They're called "homeless shelters", and generally speaking they don't solve any of the problems the article discussed.

People need actual homes. Even if it's a modest efficiency apartment, we all need a place we can call our own - where we can keep our stuff, manage it how we choose, be alone or with only the people we chose, feel safe, and be assured that in the future all of that will still be true.

There's plenty of housing around - it's one of the big things our economy produces. It's not that hard or expensive to just provide homeless people with the same housing everyone else has. There's no reason to come up with elaborate or convoluted plans for "how to handle the homeless problem" when the answer is facepalm straightforward.

> If you were interviewing a cook would you hire them having never tasted their work? I doubt it.

A cook is someone who can be hired with very little experience. A chef is someone who is trained professionally. And plenty of chefs are hired without a "taste test" based on their academic and employment history.

They're hired on a provisional basis, true, but they are paid while they prove themselves.

I bought a cupcake back when they were kits. It was fun to build. Soldering my own stepper drivers was kind of cool. They were a great step between nothing and full DIY. I feel like i could build one from scrounged parts now.

It's not a good printer. belts slip, hard to keep the heat consistent or even know what a good heat is for a given model. i can futz around with it for a couple of hours and then get good prints for a while, but any downtime and i forget all the special little tweaks to get a good print. I probably have around a 1 to 2 ratio of successful prints to failures.

Fundamentally, the thing that's holding back 3d is the design software. openscad is great for what it is, but it's not like amazing. Desktop publishing really take off till mom could print a banner on the old dot matrix. Something like Broderbund's Print shop pro.

Heck, a clip on my dishwasher broke. it was way easier to just order the part. I still feel a little guilty about not printing up a replacement, but it would be dozens of hours for a $10 part.

They are a fun toy, i'd recommend going reprap or something and just figuring out how to make one. Actually doing useful work with one (even a cheap commercial one) would require a lot of discipline and willingness to fiddle with things.

If you just want one to design your own parts, hit up shapeways or one of the alternatives. send them your dxf get a thing. it's cool.

Regardless, diy or outsource, I'll bet you a nickle the design software is what holds you back. Blender is awesome, but not easy. openSCAD is awesome but not easy. etc...
When the creators themselves are saying they don't consider it secure, I don't think it's "FUD".
Totally. YMMV. That's why you look for stuff on the CV like willingness to experiment, play with OSes at home, "describe your home network", etc. This doesn't replace the interview, it just verifies claimed competence and helps show thinking ability.
Bacteria are, in general, much more capable at processing various chemicals than humans are. They can even pass around packets of genetics, called plasmids, across species. So it isn't really surprising if bacteria can flourish eating something that tastes sweet to people, but doesn't provide any calories to people. There have been some artificial sweeteners shown to hurt bacteria more than people - Xylitol is famously used in gum, for example, because it costs bacteria energy to try to eat it, but they gain nothing, thus helping to fight bacteria growth.
Doesn't seem so strange - if you create a sugar deficit in your body by significantly reducing your intake, wouldn't you expect the body to be more responsive to sugars when it encounters them?

ABS is a sturdier plastic that's more resistant to heat, light, water, etc. The Dremel can only do PLA. The major difference when printing is that ABS shrinks when it cools so you need to keep the base of the print hot to keep it from popping off of the print bed. So ABS is a little more work but is a sturdier plastic.

Jumping from this to "therefore evolution" is exactly as specious as jumping to "therefore culture." Actually moreso, because it's cultural by definition; the question is what sparked the culture.

The culture may, indeed, be rooted in biological predisposition toward the topics involved. It could also be rooted in biological predisposition toward shoving others out of a social club, and/or allowing oneself to be shoved out -- metaphorically or through literal physical force.

Or it could be rooted in a long history of self-serving decisions which have nothing to do with biology whatsoever, only people in power working to concentrate and maintain that power. Disqualifying half the race is quite a coup.

Yes, we have significant gender dimorphism in our hormones and neurotransmitters. It's very likely that at some level, that's relevant. But claiming it as the root cause is arbitrary non-sequitur. Causation has to be demonstrated, it can't simply be inferred.
> Spencer and his followers read Darwin’s On the Origin of Species as a justification for unregulated market competition and colonization.

Please. I don't know about Spencer's unnamed "followers", but he was not quite what you would call a fan of the colonialism of his day:

> That a government cannot undertake to administer the affairs of a colony, and to support for it a judicial staff, a constabulary, a garrison, and so forth, without trespassing against the parent society, scarcely needs pointing out.

> Moreover, colonial government, properly so called, cannot be carried on without transgressing the rights of the colonists. For if, as generally happens, the colonists are dictated to by authorities sent out from the mother country, then the law of equal freedom is broken in their persons, as much as by any other kind of autocratic rule.

This definitely echoes what I see as an eleventh grader. Although the only social network mentioned here that I use is Snapchat, I definitely get the sense that Instagram and Twitter are becoming more popular as medium-specific apps. Additionally, Facebook feels ubiquitous (though I don't have an account anymore) but more "formal" than other options nowadays.

And for better or for worse, teens love their anonymity.

Maybe they are/were different on Mac? The experience of owning Prompt for iOS would be essentially exactly what was described (it never really worked correctly, is still not updated for iOS 7, changelog was, in fact, a recipe for clam chowder, etc.), minus the final "2.0" bullet (which I would love to hear more about: what product did they do that with to cause that bullet to be on the list?).

(To be clear: I am personally entirely fine with the idea that software needs to be paid for, and wish they could charge for upgrades in a reasonable fashion so as to have a real business model; but the emphasis on form over function, with tons of marketing and descriptions about how pretty the software is when core functionality like terminal emulation never worked correctly, is really irksome.)

That's awesome! Are those parts open-source anywhere? Also, curious as to how sturdy those are and what exactly they're made from. In my (quite limited) experience handling printed parts, they didn't really seem like the type of thing I'd trust to hold something expensive + fragile like a camera lens.
I agree with you there, I was only thinking of flagship android devices because they are in the same class add the iPhone. I've never owned a lower end android phone, but I imagine that they don't scale downward as well as iOS would.

The claim that CAs have been sitting on SHA-1 and not migrating to SHA-2 is not entirely accurate, at least in my experience with DigiCert.

Consequently, people I know there have told me that 25% of all SHA-2 certs expiring in 2017 have been issued by DigiCert, well beyond their market share. DigiCert has migrated all but a couple hundred customer certificates expiring in 2017 onto SHA-2, and those should be moved soon.

As for CAs in general, much of the blame lies not with CAs but with the lack of SHA-2 compatibility in certain devices and software.

For its part, today, DigiCert released a new, free tool that makes it easy for sys admins to identify all SHA-1 certs in their networks, determine validity periods and how future Chrome releases will treat these certs, and help admins map out a path toward SHA-1 sunsetting and SHA-2 migration.

DigiCert will also replace any SHA-1 certs – for current customers and non-customers alike – for free. They will match the existing SHA-1 term for a free upgrade to SHA-2 through the end of the licensing period. Here’s a link from a Dark Reading article:

It's worth noting that there are many critics of this guy.
You're right, arriving at that kind of conclusion from the existence of a tutorial is bad reasoning. I had wrong expectations, I suppose.

I must thank you for pointing that link out to me, though: it said what I was trying to say much better than I could in its prologue. Namely, how hard it is to sell a functional language to old-school C people, and how Rust may have a hard time with that (even if it's not a pure functional language).
My experience with using some panic software (especially OSX Trasnmit) is that it's been stable and supported with new versions for the last few years. Same with Unison.

They do charge for major version changes, but I don't see how this is any different from any software company that makes software. The major versions go on for a few years, and they offer discount pricing for upgrading.

I might be wrong but the ancestry of the "rule" was some sort of statutory rape disqualification. Follow that rule as an adult in (insert state here) and it was a get out of jail free card for the guy even if the girl was technically underage. To handle those annoying "he's 18 and one day while and she's 17 and 11 months and 29 days old" situations. So technically you can't consent till you're 18, but if one partner is 18 and the other is 18/2+7 aka 16 or older, its not illegal. Needless to say this is not legal advice and I don't remember the state and it once being true in AL in 1920 doesn't mean its true today, anyway.

(and I'm getting downvoted. thanks guys. My point isn't that its great not to prosecute rapists or make a statement about some weird moral/ethical perspective on dating younger women or that I totally confused the article with some legal debate, but to point out that AFAIK this "common sense math formula" originally came from a statutory rape law in the American south decades ago, and thats the answer to the debate on HN of "where did this supposedly well known law come from that no one knows the source of" Perhaps given this as a start someone who knows the history of those laws, perhaps in the south, could confirm the details? I'm not asking you to agree with it, or promoting its reinstatement, just stating its history)
> It seems entirely designed to keep the high school experience of constantly worrying about what everyone else is doing and thinks about you front and center through the rest of your life.

I think this is true if you choose to make it that way, but for a lot of these, it really doesn't have to be that way. For example, I have a small (~10) number of friends on Snapchat; we generally share tiny tidbits of our life that we enjoy, and it helps us to know each other a little better in a manner that doesn't invoke jealousy.

it's more than just a "per kg" dosing as well. Rats/mice have a very different level of metabolism than humans do just because of scale.

Basically there's a fudge factor of 0.75. Of course, the following article goes on to explain that it's actually drug mechanism dependent as well. Very complicated stuff!

"The value of the exponent for whole body metabolic rate was originally calculated by Max Kleiber in 1932 to be 0.74 (Kleiber, 1932). A few years later, Brody et al. published their famous mouse to elephant curve and calculated the exponent to be 0.734 (Brody, 1945). A value of 0.75 is now accepted because it is easier to use, and the difference from 0.734 is considered to be statistically negligible (Schmidt-Nielsen, 1984). However, it should be noted that exponents in the range 0.6–0.8 have been reported for metabolic rate (Agutter and Wheatley, 2004). A value of 0.75 means that the whole body metabolic rate increases as body weight increases, but to a lesser extent than would be expected of a simple proportional relationship. It follows on from this that the specific metabolic rate (the metabolic rate per unit mass) decreases as animals get larger (the exponent is −0.25); the metabolic rate of 1 g blue whale tissue is 1000 times less than that of 1 g shrew tissue (Kirkwood, 1983)."

I guess I'm having trouble figuring out where the numbers are coming from.

I'm seeing that the FDA recommended maximum dose for aspartame is 50mg/kg/day. Assuming a 70kg Standard Man, that's 3.5g/day of aspartame. Diet Coke has 125mg per 12oz. can, so that would be 28 cans/day. Each packet should be around 35mg aspartame, so 100 packets/day (the amount of aspartame per packet was hard to find, and the approx. was from an American Cancer Society article).

Agreed that 9–12 packets doesn't sound like much, but I think we're talking way more than that.

The mechanism of toxicity (in dogs) is specifically relevant. There are multiple studies showing that artificial sweeteners in general are unhealty -- the body recognizes them -- and takes a variety of actions as a result.

Forget creepiness - there's the issue of biological clock in women. Any man who wants to have kids pretty much has to work with an age ceiling.

I was actually surprised to see such a linear age range band, but maybe it's because it's so normal to have multiple marriages/divorces and such now. (I'd assumed men would have a bit of a ceiling for the age they were looking for around 42 or 44.)

They've made it clear that they're in the business of being a media company, not a technology company.

Slightly offtopic, but I'm feeling a little ranty.

This whole idea that two adults cannot engage in a romantic relationship without being unnecessarily harassed, based solely on their ages, is ridiculous. Just because it makes you uncomfortable doesn't mean that the people involved are uncomfortable, being taken advantage of, or naive. It just means they have found apparent happiness in another human being. It's no one else's business and judging others based on the age of their partner (assuming both are consenting adults) should be stopped.
The test I describe should take an hour or two - it's a test of "can you actually do these things your CV claims you can?" Which is nontrivial, but I enjoyed taking it (fix a broken thing!) and feel fine about giving it to others.
The word "creepiness" is nowhere on that wiki page and I don't believe that creepiness is strongly associated with that formula attributed to Maurice Chevalier. To clarify what I mean by "associated", I'm talking about typical people holding both that formula and the "creepiness rule" as interchangeable labels for the same concept.

There is certainly some overlap between the two concepts but a 43-year old woman would understandably find a 73-year old chasing her a little "creepy" even though the she's within acceptable range of that math formula. Therefore, the "creepiness rule" is something else outside of that formula.

Another difference is the age/2+7 formula is a guideline for how society (the non-participants in the relationship) perceive the age disparity. The "creepiness rule" is more descriptive of how the participants perceive potential partners.

The article was interesting for its history of prison gangs.

However, if you're going to write about anything, then you owe it to both the readers and the subjects to interview the people involved.

You're not going to get an interview by walking once down a cell block asking to talk about gangs. No shit. The people who create shows like "Jail" or "Lockup" manage to get hundreds of hours of interviews with gang members. However, they establish mutual respect and rapport.

I suppose I can't judge too harshly as it's certainly a difficult assignment, but it seems like the author put a very minimal amount of effort into interviewing, and instead pontificated from on high about gang members.
The probability of accepting an inferior tour is a function of how much longer the candidate is compared to the current tour, and the temperature of the annealing process.

Shouldn't the distance of the "nearest" neighbor be a function of temperature, rather than (or at least in addition to) the probability of acceptance? Isn't that how simulated annealing can escape a local minimum far from better or global maxima? Intuitively that is how the real annealing process works.
