mcmancini··on Georgia Tech Student Indicted in UGA Hack
Is this actually only about the calendar entry, or is there more to the complaint? From a separate article at Online Athens (http://onlineathens.com/local-news/2014-12-03/uga-continuing...):

>Elsewhere in UGA’s digital realm last week, the career center was hacked with fake Internet addresses. The Internet address walmartacademy.com directed people to the University of Georgia’s main website, and the address ugagrads.com directed people to McDonald’s online career page.

mcmancini··on Apple has lost the functional high ground
I think this observation is spot on. My parents are in a rural location and for years had horrible random and difficult to trace problems with their computers while they were on satellite internet. The mysterious problems went away when they were able to upgrade to cellular internet. I think the problems were due to the painfully high latency over the satellite connection, but in many cases it was difficult to prove.

Another personal frustration, which perhaps you might share, is the implicit assumption that everyone not only has high-speed internet, but uncapped internet service. My parents had a hefty internet bill the other month because my dad upgraded his iPhone, and there was a lot of occult downloads happening, I assume for Photo Stream or whatever it's called now.

mcmancini··on Baseline Mac OS X Support merged into FreeBSD package manager
Isn't there a way to have Homebrew monitor a "make install" operation so that Homebrew can manage (or at least be aware of) your own installs?
mcmancini··on Nashville police chief shares message, responds to questions
Thank you for doing so, this was an enjoyable and interesting read that I probably wouldn't have found otherwise.
mcmancini··on Eggs Not Always What They're Cracked Up to Be
"Almost every other country" doesn't wash their eggs, which strips the protective cuticle that allows eggs to remain safe at room temperature. They also immunize against salmonella.

Again, do you have any sort of credible scientific basis behind your claims?

mcmancini··on Eggs Not Always What They're Cracked Up to Be
Your advice seems to contradict the FDA: http://www.fda.gov/Food/ResourcesForYou/Consumers/ucm077342....

What is the basis for your claims?

mcmancini··on “I am not authorizing you to release a Ruby port of Metaphone 3”
Don't know about them.
mcmancini··on “I am not authorizing you to release a Ruby port of Metaphone 3”
No, the license allows one to offer engineering services to the public and the PE title is granted in recognition of that right. It is generally illegal to call yourself an engineer, but most people are able to use the industrial exemption. Nevertheless, in using the industrial exemption one is not offering engineering services to the general public. I don't know what happens if you tried to use the industrial exemption but offered services to the public, but I think it's prohibited.

This all varies between states, but in general, if you for example started a software consulting firm called Vlad Engineering and the principals were not licensed, your local licensing board would likely have beef with you. If you were a software engineer at Vlad Consulting you would probably be okay.

The bottom line is that it's tricky to navigate, and so it was recommended at my school we avoid using engineering anywhere unless we had our PE license.

mcmancini··on “I am not authorizing you to release a Ruby port of Metaphone 3”
Sort of; they were likely never engineers in the first place. Engineer is a licensed profession, like physician or lawyer. You can graduate law school, but that doesn't make you a lawyer; passing the bar does. In the US, it depends on the state, but the easiest path towards licensure is to graduate from an ABET-accredited undergraduate program. Some allow you to proceed to licensure without that, but it requires extra experience to compensate.

ABET does accredit international programs.

mcmancini··on “I am not authorizing you to release a Ruby port of Metaphone 3”
I'm not sure you're informed on this topic.

The whole point of having ABET accredit programs is to standardize a basic body of knowledge. Curricula in mechanical, chemical, electrical, and biomedical all include solving DEQ and PDE systems. Solving those without Laplace transforms is cruel, once the basic principles are understood of course.

If it's just a goddamn title, then you wouldn't be so insistent on using it. You want to use it because it implies a level of education and professionalism. It's crass to use the title because there is such a thing as software engineering, and the people most strongly insisting to use the title don't practice it. Like I said, you can legally use it, but licensed engineers are rolling their eyes when your back is turned.

mcmancini··on “I am not authorizing you to release a Ruby port of Metaphone 3”
No, and the US has an "Order of the Engineer" modeled after that. It always seemed silly to me to wear a ring on your working hand when the first thing you do when working with your hands is to take of jewelry.

"Engineer" is a protected job title in the US, but most are able to operate under an industrial exemption and so legally use the title.

The reason why some are picky about the title is that it is a licensed profession, and has some expectations associated with it. If someone tells me they're an engineer, I assume they know how to use a Laplace transform, because that's common across disciplines at the undergraduate level. Same as applying perturbation theory at the graduate level. Same as having a common corpus of basic science knowledge. Same as with professional code of ethics. Etc.

To use your own logic above, calling yourself a software ninja doesn't make you a ninja, and calling yourself a software engineer doesn't make you an engineer. It might be legal, but it's crass.

mcmancini··on “I am not authorizing you to release a Ruby port of Metaphone 3”
Or Texas. Or, as I have heard, Florida. Now that there is a proper software engineering PE exam, maybe more states will follow.

It makes sense for safety critical areas to hold people to professional standards and legal liability.

mcmancini··on “Complete Acquiesence”: How the Pontiac Aztek Happened
Your coworker should look into a minivan with fold-flat seats. I rent them when I needed to move equipment. They have great cargo carrying ability with the flat floor, plenty of anchor points, and not having to worry about where to stash the seats is really convenient.
mcmancini··on Ask HN: Embossed numbers on credit/debit cards
You're probably living in a city? Outside the city limits, where connectivity can be marginal, it's not uncommon to need to run a card through the carbon copy imprinting thingy. Seems to happen most frequently at old gas stations.
mcmancini··on The Magazine: The Book (Year One), Free Download
I had a subscription in the beginning and cancelled it. I was expecting something along the lines of a high-tech New Yorker, but The Magazine never met my expectations.

There was also a level of pretense and hipsterism in The Magazine that was really off-putting (it starts with the name even!). Of course, the New Yorker is even more guilty (cf. diacritics and refusal to acknowledge the existence of "flyover country"), but in the case of the New Yorker, the quality of the long-form reporting is phenomenal. I guess you could say I came for the reporting, and stayed for the rest. With The Magazine, there was an article every other issue or so that was of great interest, and the rest were "meh".

When I look at the list of authors for The Magazine, I see many forming a loose-knit group of friends and associates. I think that kind of sums it up for me: it was a product written for each other, not for the wider public.

mcmancini··on Sci-Fi Novels You Should Read
Sounds awesome, thanks for the tip. The comments on the HN thread have been far more fruitful than the original article, in my opinion.
mcmancini··on The Horror of a 'Secure Golden Key'
Agreed. That was my first thought when law enforcement started getting press for screaming "think of the children". I'm surprised and disappointed that people have apparently forgotten recent history.

This is why I greatly respect historian as a profession.

mcmancini··on Plastc Card
The problem I have with this product, as well as Coin, is that seems to be far less convenient than pulling a card out of my wallet. Maybe George Costanza would get some use out of one of these, but I'm usually choosing between an ATM card or one or two credit cards. Plus, I don't need to worry about having my phone, charging batteries, electrical gremlins, &c.

All I'm seeing is an expensive ($155?!) solution to a non-existent problem.

mcmancini··on The 2014 Nobel Prize in Physics
One of my labmates from grad school did colloidal quantum dot synthesis, and he regularly cursed Ostwald and his infernal ripening. Just general curiosity if it came up in this area, and if so, how it was dealt with.

By the way, your series of posts on this topic have been superlative—many thanks.

mcmancini··on The 2014 Nobel Prize in Physics
Is Ostwald ripening a problem?
mcmancini··on Glut of postdoc researchers stirs quiet crisis in science
Yeah, I hate to stereotype biologists but it's true, there is a serious safety culture deficiency.

I learned cell culture from a guy that didn't wear gloves while working under BSL-2 conditions. Back then, I thought he was so cool. Now, what a moron.

mcmancini··on Glut of postdoc researchers stirs quiet crisis in science
In this case because participating in the system by playing the tenure-track lottery helps to sustain the system, among other things.

The academic system is badly broken. Personally, I think that the only winning move is not to play.

mcmancini··on RamanPi – The 3D Printable Raspberry Pi Raman Spectrometer
Nonsense, you can run a perfectly good student lab with a cheap notch filter and pull a usable spectra off something like polystyrene or Tylenol. What I'm wondering is if this thing could even do that. Looking at the abuse the diffraction grating has taken suggests the answer is no.

As far as a decent scientific bench instrument goes, we're mostly in agreement. I'd love to know if you could make a decent optomechanic system like this on a SLS with a metal substrate.

mcmancini··on The $1,200 Machine That Lets Anyone Make a Metal Gun at Home
Everything he used can be found in a home workshop, especially the workshop of someone with metalworking experience. I'd guess you'd have easier time finding these tools than a home CNC mill that can handle Al.
mcmancini··on RamanPi – The 3D Printable Raspberry Pi Raman Spectrometer
A custom housing could certainly be on the order or more expensive than the optics, but if you were using catalog parts the mechanics should not be the largest cost.

For example, a "cheap" 1" notch filter from Thor would run about $500, whereas a kinematic mount would be somewhere closer to $40.

mcmancini··on RamanPi – The 3D Printable Raspberry Pi Raman Spectrometer
This is neat, but I wonder what the actual resolution of this device is (and how stable are the measurements)? Is it useful for anything other than just novelty?

Not sure that I really see the point of 3d printing the parts (although scratching many geek itches, yes) when your optics are going to be a much larger cost than the mechanical mounts, and the quality of the mechanical mount is so very important.

And to underscore how a usable rifle may be constructed with readily available parts, I present a personal favorite, the AK-47 built from a receiver recycled from a shovel: http://www.northeastshooters.com/vbulletin/threads/179192-DI...
mcmancini··on A strange green organism has spread, clogging up the world's rivers
This crap has been a PITA a for flyfishers for a while. Rock snot is an apt name for it because it is treacherous when you're wading. Personally, I prefer felt boots because they have better traction, but they're also an easy vector for didymo and it's just not responsible to use them anymore since I'm in multiple rivers. I ended up switching to rubber boots. Not nearly as nice to walk in, but far less likely to have didymo hitchhiking along when practicing proper river hygiene.
mcmancini··on ‘Cloaking’ device uses ordinary lenses to hide objects across range of angles
A preprint of the relevant manuscript is on arXiv: http://arxiv.org/abs/1409.4705
mcmancini··on Pebilepsy – Pebble app for seizure tracking and measurement
I would guess that collecting data in this case could still fall under regulatory preview, and that you would also need to qualify your sensors (Pebble) too.

It really would be best to speak to someone familiar with Canadian medical device data. Much cheaper to do things right from the start (e.g., develop under IEC 62304) than to fix things later after getting a nasty gram from the Canadian FDA equivalent. Maybe through very careful marketing you can work around potential problems, or maybe not. I think that this project is in an area that requires an expert opinion, however.
