I hate reading articles like this because it's trying to tell you that CrossFit culture is all about pushing yourself until you've practically killed yourself doing all sorts of crazy and whacky weight lifting. 99% of the time, the problem isn't CrossFit, it's the coaches. If you're at a good gym (or box as it's called), the coaches know how to scale workouts for the athletes so they won't get hurt, and they're programming workouts so that people aren't killing themselves constantly.

Where CrossFit is to blame is its low barrier to entry to becoming a coach/affiliate owner. All you need is a weekend of your time, $1000, a passing score on a super simple test, and you get to call yourself an "L1 CrossFit Trainer." They don't advise you to immediately go start training people, but there are plenty of boxes that will let you jump in and start coaching classes. It's gotten so popular now that there are bad affiliates popping up out there that have horrible programming that hurt people, and then articles like this get written, and then everyone thinks that's all CrossFit is.

When you take the L1 CrossFit Trainer course, they have a whole section about "Uncle Rhabdo." It's a very rare thing that occurs when you do a whole lot of isometric exercises (like strict pull ups where you come down real slow) when you're not used to them. It's not a rabid thing that is 100% going to happen if you do CrossFit.
hahahahahaha. Its true, but the Waterloo giant going down still saddens me. Well, it had its glory days.
> There can be concerns about the ability to actually write code, the ability to be practical, to be OK with working with unclean data, the ability to get stuff out the door and have a hacker mentality, etc etc.

These all seem to be concerns of someone who does not what doing a PhD entails, really.
Unmentioned in the article: New York has strict regulations on check cashing that limit fees. Roughly 2%. Only a few states do this, some limit it at 5%. The check cashing business is very different in those states that don't have such limits.
> (Ironically, a check that was bad because of the fee taken for 'a')

This is a real big problem in these kinds of situations.

To give you an idea of how this happens: when I was in college, I worked at a pizza shop. It was Thursday. I got paid Friday. I thought I had $20 in my bank account, but I didn't realize that day was the day that my World of Warcraft subscription was up, and that was $15. During the course of the day, I bought lunch, a snack, and some pencils or something. All that total was less than the $20, it was something like $10 for lunch, $2 for the snack, and $5 for the pencils. So I was good.

I wans't good. They applied the charges like this:

Starting Balance: $20
WoW: -$15
---------------------
$ 5
Lunch: $10
---------------------
-$ 5
Overdraft fee: -$35
---------------------
-$40
Snack: -$ 2
---------------------
-$42
Overdraft fee: -$35
---------------------
-$77
Pencils: -$ 5
---------------------
-$82
Overdraft fee: -$35
---------------------
End total: -$117

Now, what sucks is that if they had processed them in a different order, it would have looked like this:

Starting Balance: $20
Lunch: $10
---------------------
$10
Snack: -$ 2
---------------------
$ 8
Pencils: -$ 5
---------------------
$ 3
WoW: -$15
---------------------
-$12
Overdraft fee: -$35
---------------------
End total: -$47

Still an expensive mistake on my part, but it's more subtle than 'made a bad choice.' I was able to convince the bank to refund two of the fees so I was only out $40, but that extra $70 was a _massive_ amount of money to me at the time. It basically meant that I could only exactly squeak by for the next month, since that was basically all of my discretionary income. You can construct a similar situation which would have forced me to then take out a payday loan to make my bills, had I made one or two more mistakes in that same timeframe.
This article seems a little sensationalist. Just because a journal had an article about it with a cartoon attached doesn't mean they've adopted as a "mascot" or make light of the condition.

My wife has been doing crossfit full-force for almost a year (including some competitions [1]). Along with previous standard workouts and diet changes, she's lost 60+ lbs over the past 2 years. And she's getting pretty buff.

She's never heard of rhabdomyolysis.

Every exercise/activity has some risks. If anything, I'd say crossfit puts you at risk for other injuries (back, joints, heat exhaustion at competitions, etc.).

In the past three days, I've read that the following companies are doomed: Facebook, Microsoft, Apple, LinkedIn, and Samsung.

Good thing I have so many blog posts to tell me about it! Otherwise, I don't think I would have noticed. After all, it's pretty hard to tell that Facebook is doomed, what with all the numbers.
I really like it and its entirely analog nature is refreshing. It makes sense to set aside something like a raspberry pi for it (I would never use a PC, especially on update tuesdays. And I would not want to set my PC audio to full blast so the output swings the full +-2.5V).

Mechanically delicate though. Vibrations disturbing the surface of the liquid will skew the print and cause poor layer adhesion. And you have to make sure your surface is perfectly level.

Well, I think the article did get one thing right, something that many articles about poverty don't, and that's the kinship and us-vs-them attitude that tends to be a factor in decision-making among the poor.

Check cashing places are a lot less formal than banks (when formality is intimidating), and they tend to say "no" less often. They're more of an ally to the poor than most people would think.

But, yeah, the article should've mentioned Chex Systems.
Since the article is not about working out in general but CrossFit specifically, and not about restarting exercise after a break, and particularly since the takeaway of the article is that it is hard to recognise this syndrome, I'll take that with a pinch of salt - best not to be complacent.

I agree re. working out in general - but this is about something more specific.
What if you made the app cost $0.99 and that included the first postcard?

You get far, far fewer purchases, but each purchase is a far, far more qualified customer, plus, you can almost break-even on the one-and-dones, and you may make enough money on the breakage to make it tiny profitable.

I get that tiny profitable isn't a VC's goal, but for a side project that's dying anyway, this might make the runway infinite, which you could use to rattle around and maybe find a winning model, or just let it run and not cost you much.

Take your Ph.D off your resume.

Real world software production needs little "computer science" expertise. There's too many Ph.D.s that take a research angle on projects. The goal is to design/implement/test/ship/support/improve and make money.

Best programmer I ever met didn't graduate high school.

Supply and demand determine wages. Ph.D. does not entitle to more pay. The industry simply does not rely on credentials like, say , the medical industry which does require an M.D. for the best paying "line" jobs.
A couple random observations:

* The overwhelming majority of vendors here list Dual_EC_DRBG along with the HMAC and CTR DRBGs. A reminder: Dual_EC is a catastrophically slow CSPRNG that relies on bignum multiplication; if you pay any attention to crypto performance at all, you have every incentive never to use Dual_EC, and to an almost reasonable first approximation, nobody does. The HMAC and CTR CSPRNGs are innocuous designs based on simple conventional crypto.

* I'm a little suspicious of this list because it suggests Windows Server 2008 and Windows 7 use only Dual_EC. Neither do; you'd have to go through contortions to make Windows use Dual_EC. Obviously, the list is about certifications and not actual field configurations, but still, you should know: Windows does not rely on Dual_EC.

* Here are the products (other than Windows, which, see above) that are listed as only certifying Dual_EC:

Lancope
Mocana
McAfee Firewall Console
Thales Datacryptor

None of these are particularly important industry products. McAfee is not a leading firewall vendor (Cisco and Juniper are). Lancope is a niche intrusion detection product, and Lancope is not exactly a hotbed of cryptographic research, if you get my drift. Also, the CSPRNG Lancope would be using would be relevant only to their admin console. I don't know what Mocana or Thales do, which could be my ignorance showing, or it could be telling given what I do for a living.

Here's what Bruce Schneier had to say about the Dual EC DRBG:

"If this story leaves you confused, join the club. I don't understand why the NSA was so insistent about including Dual_EC_DRBG in the standard. It makes no sense as a trap door: It's public, and rather obvious. It makes no sense from an engineering perspective: It's too slow for anyone to willingly use it. And it makes no sense from a backwards-compatibility perspective: Swapping one random-number generator for another is easy."

This is basically my take on Dual EC as well. I am not putting it past the NSA to backdoor a crypto standard (I would bet against it being a NIST standard --- if they backdoored a standard, my money is on a telephony/RF one --- but I would not bet my house against it). But this would be an inexplicable backdoor to add.

I disagree on the premise that audio glitches can and do happen on non-realtime operating systems due to the lack of guaranteed scheduling. For this 3D printer, it doesn't really matter, but for a lot of other things, I would feel uncomfortable trusting a desktop PC soundcard, OS, and drivers to perform glitch-free audio I/O. I would much rather send self-clocking commands from a PC to a hardware device which takes care of the realtime task on its own.
American HNers, is this really a thing in the US?

As a so-called "millenial" in the UK, I just can't imagine myself, or any of my peers, actually bringing parents into job interviews.

Surely there's something wrong if, after 4 years of college, people are so unprepared to stand on their own two feet.
Sorry but I hear a lot of speculation, not real reports of hard actual life threatening changes.

Maybe soft ones like the sea temperature and acidity, but most people can still go out and food still grows.

Thx for the advice, especially the comment about the time-scale of the process.

I agree with you about how terrible that is, but that's bad policy. It is not fraud because it is legal, even though the law may be crazily ill-advised and pander to a particular constituency.

Rehash from five years ago? Doesn't this guy know that the new scandal is high-rep box jumps?

The "dirty secret" of Crossfit is that they don't do much to actively ensure the quality of local affiliates, and therefore the brand doesn't always mean much. My personal experiences have all been great, and my coaches have always been extremely safety-conscious, but in light of the nasty things I read on the internet, I wouldn't encourage anyone to blindly trust whatever local Crossfit affiliate happens to pop up down the block. Rather than thinking of Crossfit as a guarantee of a certain standard of quality, think of it as an approach to fitness that is interpreted in various ways by coaches of varying competence.

Also keep in mind that the coach can't always see when you need to ease up or stop. Sometimes they can, but they can only see what is apparent on the outside; they can't feel what you feel.
How do you choose a name for anything anyway? From company names to personal blogs, naming them is a fruitless exercise. In the end you're trying to be clever but instead you end up with something that means wang in vietnamese or is inspired by a straight quote from a line in a book you think fits your character but is really something that speaks to a hundred million people, which is the exact same number of people who read the book in the first place. Then it sounds either obscure or cheesy.

Those two sentences make perfect sense. People go to Facebook to socialize, to Google to search. This naturally leads to the conclusion of Facebook going with very constricted models of monetization like having intrusive ads, selling your private information, showing sponsored posts. Google is in a more natural position to advertise, it doesn't have as much to gain by showing you annoying ads as Facebook. In addition to all of this, Google does not seem afraid to venture out into completely new areas. I'm not saying Google is an innocent saint that'll never do any wrong, but it's pretty clear Google's future is markedly brighter than Facebook's. It'll be interesting to see how Google+ shapes in the coming years. One interesting possibility is Google+ having no ads at all (it currently does not have any) for all of its life, because Google can afford to do that and everyone will like that.
She would fit nicely into category 4 though.

There are a ton of things wrong with crossfit like their insistence of doing skill lifts for time. But training too much? That's actually your choice.
> The software we wrote as an add on to blender takes the data from that 3D model and translates it into an audio waveform. It then plays the audio file out to the printer through the headphone jack in your computer. This waveform drives a pair of electro magnetic mirrors. The higher the volume, the higher the voltage, the more the mirrors move. The purpose of these mirrors is to reflect and control the path of the laser beam. By using the audio waveform generated from the 3D model data to drive the mirrors, we are able to get the laser beam to draw out the shape of the object. That's takes care of the X and Y axes.

I look forward to people doing weird interesting things with this!

I have no idea how lissajous figures could work, but they're cool and in 3d resin print they'd be cooler.
Except those debit cards have all kinds of predatory fees. They're smaller and predictable, but way more expensive than using a checking account from a credit union correctly.

"Any" exercise done in excess can trigger this. I suppose Crossfit's characteristics make it easier for it to happen

"You’re supposed to push yourself to the limit, but when you hit the limit and pay the price, you’re the idiot who went too far." Isn't it? There are several "coaches" that only know how to push people but have no regards for personal limits

Diet can also cause rhabdomyolysis http://www.ergo-log.com/vegerhabdo.html (in this case, because of lack of protein - not necessarily because of vegetarianism)
> Google has been public for 9 years now, facebook is just over a year.

Google business model hasn't changed from the day when they figured the masses will pay for clicks (circa 10 years ago).

Facebook, on the other hand, continues to struggle and fail to figure out any meaningful way of making money (facebook credits??), other than selling users info (mostly indirectly) to those with fat wallets who scam masses with fat burner pills and muscle gainers from deep wild amazonian river. And this will continue to piss people off (or in other word, won't bring much value to end-user).

When most connections between lost moms and sons, friends and families, ex-co-workers and crushes from high school had been already re-connected, Facebook stops bringing any extra value. Just exactly how many times you spoke with your old crush before you realized she is fat now, got plenty kids and live on the other continent. Your connection with said lead will fade away and disappear at some point, just like you naturally had a damn good reason to lost a track with her at the first place, before Lee (and Gore) invented the internet. The same token just like today, you woke up 5 years ago, and with God's help you will wake up in next five and go to Google (or your SE of choice) and type a new search for something new you want, you need or you are interested of. Regardless of AI progress this will not change much in next X or XX years.

It would be shocking if Cisco were using Dual_EC in any "traffic-scale" crypto in their devices. It isn't just extremely slow, but also slow in a way that makes it obnoxious in embedded environments.

Is the resin for this a standard type of resin? Seems like you don't get much of it with the kit.
correct interpretation of my shame. All my friends have read Neuromancer, when they talk about it only think I can do is to try drifting the topic on something else.
Funny, but it might be helpful for things like salary negotiations.
if facebook is able to continue on their mission of "connecting" people and using the registered folks to figure out ways to make it useful, i am sure they will be around for a while.

maybe if it became less "buzz worthy" (ie, teen-focused) and more boring/pragmatic, it could find even more uses for the network and ways to be ubiquitous for a long time. seems like they could displace a lot of firms out there - linkedin being an obvious example. (i know everyone has linked in in a different mental box than facebook, but that could change.)

of course - no company lasts forever. very few companies sustain for 30-40+ years. it's not necessarily a reflection on "the company" that this happens, virtually every company is flawed in some way and time exposes the cracks and can break it apart.

Can the writer of this article read what he's saying? "Fb is lame because they're just using my data to sell me annoying ads...Google on the other hand is learning about me with my data!" (Which they will use to sell you ads)
This doesn't really work, though, because to the 3D printer, 0 volts is a valid signal in the domain of the input. Never use a value in the domain of your input as a null value. Additionally, it is difficult to define what the sound level of a continuous signal really is, since it is usually computed using an averaging, integrating, or low-pass filter (not sure which.) Just like an old-fashioned VU meter, it takes a moment for the needle to fall down to 0. By the time this happens, the glitch is over.

Also, consider that not all audio glitches are of the type that cause zeroes to be emitted. Some audio glitches are known as buffer underruns, where the ring buffer holding audio is not filled up in time, and eventually runs out, causing the same few milliseconds of audio to play over and over again until more audio makes it into the buffer.
Not a very good article. The author implies that there will be a mass migration of users to another service if Facebook remains stagnant in terms of carrying out acquisitions. But Facebook continues to improve and update the user experience, so there is little incentive for users to move to a would-be competitor. Not when they already have connections with family members, close friends, and many others. Facebook has very much become a part of many users daily lives like using the Internet, and users have already invested a lot into Facebook; it's like a sunk cost. FB may remain static (in the same niche market) if they don't carry out more acquisitions, but that's (may be) fine. They can't be "doomed" just because other companies are carrying out more acquisitions.

What I find particularly curious about this post is how much this particular author wants to climb back into his mother's womb. I'm not being flippant or glib, re-read the post if you didn't catch it the first time around. He wants technology to think for him, he wants technology to coddle and embrace him so he doesn't have to think for himself. Google will drive him places, google will read his emails and predict his wants and cater his technology consumption to his whims, google will blast his retinas with all the contextual information he'll ever need without having to retain it or know it for himself. He's hoping for the technical equivalent of an antimitotic sac with Google branding all over it, washing him with vital information nutrients.

He also doesn't seem to get Facebook from a socioeconomic standpoint. Facebook doesn't need to do all of these things that Google might do. Facebook just needs to let you feel not lonely when you are feeling lonely. Facebook just needs to connect you with those you aren't necessarily really connected with. Facebook, like it or not, is a new form of communication the same as the phone was, email is, SMS is, etc. The market will decide the value of that.
