Saying that all experts are bad teachers is like saying all <insert ethnic group> are <insert stereotype>.

Good teachers are good teachers. If the good teacher is an expert, then they are better than the good teacher who is not an expert, especially if they are trying to teach a nuanced topic.

Does every teacher need to be an expert? Of course not. But plenty of non-expert teachers will actually lead students astray by teaching them the wrong model.

I've had plenty of "bad teachers" who were experts. I've also had plenty of "bad teachers" who were not experts. I've had very few good teachers, period. Bad teachers in lower-level topics are not noticed very much, but they are the bane of undergraduates who are subjected to them often. Survivorship bias might lead me to conclude that most experts are bad teachers, but the better explanation is simply that teaching and being an expert in field X are distinct abilities/skills, and that it is rare to find people who have mastered both.

I aim to be an expert in my fields (currently 3 disparate ones in which I hold degrees). I also aim to be a good teacher, which means that I take time to figure out the best approach and experiences for teaching a particular topic. I consider my expert status to be an advantage that complements my teaching ability. Being an expert does not make me a bad teacher. Being a bad teacher makes me a bad teacher.

Here's my list:

- Using Vim. Just do it. You'll be more productive than in most other editors, and you can use it over ssh on pretty much any machine.

- Using Python. Batteries included means less work for you to do.

- Using Django. Ditto

- Stopped chasing the latest and greatest JS framework and just use what I know (jQuery and Angular lately). Not worth my time when I already feel very productive.

- Use puppet for every server configuration, from my home NAS to every production server.

- Learned 3D printing/joined a hackerspace. Working from home sucks for social life and for developing business connections.

- Learned some basic UI/UX ideas.

- Started sleeping more. This is huge for productivity and my happiness.

- Realized that buying off-lease/gently used cars is much more economical than brand new. You can drive a 3 year old BMW for the same price as a 2 year old Honda Accord.

- Listened to Roll Play, especially Swan Song. Better entertainment than most TV shows.

- Stopped paying for cable and signed up for Prime, HBO Now, and Netflix. This isn't even to save money, but to not have to watch commercials.

- Discovered polyamory.

- Realized that I can build electronics on the cheap.

- Hired a personal trainer to get in shape, instead of trying to go it alone.

- Bought a double walled steel water bottle.

Sorry if this is too long.
Have you tried bike riding, like with a good road bike? I find it a great deal more fun and exhilarating than running ever was.
Apple's Genius Bar Is Dead
With all respect I do not agree with your example for the lhc .
For two reasons primarily:
The first has already been mentioned about various groups and experiments / detectors.
The second, I think is more important. In order to claim discoveries at any of those experiments certain statistical constraints must be met. The 5 sigma rule is by its very nature garnered by repetition and is a necessary because of the nature of quantum mechanics and particle physics. Here is a write up on cern and 5 sigma
http://physicsbuzz.physicscentral.com/2012/07/does-5-sigma-d...
I think there's also a certain lack of transparency in the scientific process that needs to be fixed. But that's just like my opinion.
Have you already read the Xerox PARC books?

Why the Navy Needs Disruption Now
Pretty much everyone in science and academia is saying we need to reproduce results. It is a sad state of affairs, but I'm not sure why having someone from Harvard say it is surprising or different than anywhere else.

The real issue is that there are anti-incentives to reproducing other people's results. All scientists want to see it, and nobody is able to actually do it, because they'll lose status, publication opportunities, and funding. It's viewed as career suicide. Unfortunately, this article doesn't suggest any solutions to that problem.

It would be best to not suggest this problem is somehow due to "people who treat science like religion". That association isn't called for, nor is it largely true or applicable here. Ahmed even said very early in the article "the majority of irreproducible research stems from a complex matrix of statistical, technical, and psychological biases that are rampant within the scientific community."

Statistical and technical biases are common human errors that affect everyone equally and don't amount to religion. Even beliefs don't amount to religion. You and I both believe electrons run through our computers, yet I haven't verified electrons exist and I've never seen one - have you? Almost everything we know is belief based on what others have told us, whether it's science or not. Even if scientific results are reproduced, unless you're doing the reproducing, you're still subject to believing the results. It's a more believable story when two independent people verify some result, but that doesn't mean that believing one story or one paper demonstrating a result is somehow akin to blind faith, ritual, and deity worship.
You'll find yourself modded up and down over this.
In a purely intellectual sense, it is definitely a shame that the coup failed. The turkish miliatry has a history of stepping in when a government no longer adheres to the pricipals of the republic, specifically in relation to secularism.

By any metric, Tayyip's leadership is not secular.

However, the turkish people (at least according to my friends) are are badly shaken after the two recent terrorist attacks - the coup represents more violence - regardless of its 'benevolance'.

Turkey's admiration of Atatürk, the 'founding father' of modern Turkey is absolute: a benevolant dictator, he molded Turkey into a modern balanced country, uniting multiple social, ethnical and religous systems.

It is widely held that Tayyip is doing exactly the opposite: peice by peice dismantling the social balance and fundamentals of Turkey. Naturally, his actions are liked by some - but his goal is to divide, as opposed to unite.

Based upon this, the coup seems to be yet another tangile proof of the disquiet that has been installed under the Tayyip regieme.

Essentially, the turkish people have had enough of bloodshed, division and disharmony.

Serious question:

Is there any reason why somebody would use Haskell for data analysis when there is also R and Python - which are perfect for that job - except for that the respective person happens to be a Haskell expert anyway?
My reading speed is slow and my to-read list is long. I used to force myself to finish every book I started but now I'll happily give up on anything that doesn't grab me fairly quickly.

I've also been working on only adding things to my list that I actually want to read and avoiding books that I add only because I want to have read them.

Is there a title in particular that triggered your interest in reading?
What about sunglasses? They've always been popular/fashionable and they're also glasses that you wear in specific situations. They're also glasses that, underneath any styling or branding, still exist for functional reasons rather than solely for looks.

I think of headsets more like headphones. No, you don't want to have to wear headphones all day long but when you're getting something out of them, people seem willing to wear them for extended periods of time.

Even if the glasses thing is a hurdle to this becoming ubiquitous consumer electronics, I think the engineering and tech being developed still has quite a bit of promise and I'll be glad to see if they can make some real progress and show something off beyond teasers.
the authors of these patents should write resumes for a living.
Surely it's possible to be a nice guy while screwing over the cheaters.
Good. Isnt that the idea? That's what Moonshots are. Plus its hard to see returns on a moonshot in a year. This is a long term investment.
Happy Sysadmin Day – The Register's roundup of things to do
I'm sorry, I have to disagree with this. I don't see how the perception of Linux's security would have anything to do with Microsoft's pricing for Windows. As much as I wish the case were different, Linux is simply almost never considered as a viable alternative to Windows (on the desktop), except in a few rare cases which are so rare, they become big news items (e.g. city of Munich government). Both companies and individuals are too invested in Windows and its software ecosystem to even contemplate a change, except maybe to Macs. I do see more people switching to those, both individuals and companies actually (I almost interviewed at a small company that was all-Mac). So if MS quintupled their prices for Windows Home/Pro, I could definitely see that spurring a defection to Macs, though I still doubt it'd be that big because of the installed base of Windows software that doesn't have a Mac version. Also, Macs just don't seem to be set up for enterprise use the way Windows is, and while Linux can be, it takes more IT competence than I've ever seen at a large company (which these days seem to be outsourcing to external vendors anyway).
This bug's been driving us mad because we can't reliably repro it on our machines at Docker, and it only happens to a small subset of users, but is very annoying when it goes trigger. It seems to be related to the OSX version involved, but there's not enough bug reports to reliably hone in on it.

The other aspect that it may be is a long-running Docker.app -- since as developers we are frequently killing and restarting the application, it could happen after a period of time. I've now got two laptops that I work on, and one of them has no Homebrew or developer tools installed outside of containers, and runs the stable version of Docker.app that's just been released. If this can trigger the bug, we will hunt it down and fix it :-) In the meanwhile, if anyone can trigger it and get a backtrace of the com.docker process, that would be most helpful. Bug reports can go on https://github.com/docker/for-mac/issues
Even at closest approach, there won't be any appreciable change in the night sky over a human lifetime. Note that in the gallery at the bottom of http://www.nasa.gov/mission_pages/hubble/science/milky-way-c... the shortest time between frames is still 50 million years.
Hey, this is cool! Nice work. I am going to play around with this later.
It's not just money that prevents people from repeating experiments, it's recognition.

The general idea for research to be accepted is that it makes some novel, albeit small, impact on the field, acceptable for publication in a peer reviewed journal or proceeding. Repeating someone else's experiments wont get you that, so in general it wont help you graduate or move you toward a higher position at a university or in your profession, meaning there is very little motivation for researchers to pursue such endeavors.

So instead of just throwing money at the problem, we may need to entirely revamp how we recognize the pursuits of researchers.
And I'd rather have "I know way less about this stuff than they do, so until I see evidence otherwise I'll assume problems I see are due to my lack of understanding, not theirs" than either of those.

I don't have a problem with skepticism or questioning competency. I do have a problem with the attitude that a few minutes of thought and an obvious objection is sufficient to start questioning competency.
Ask HN: Is there any statistical report on Freelancers?
I am doing some research on freelancers and searching for data points related to the same.

Like how many freelancers are there online world wide?
How much they contribute to the local economy they live in.
My biggest issue with it is that there seems to be no easy way to provide more space to the VM docker runs inside. While it seems trivial it can be useful if you happen to have really large images (yes, for valid reasons). If you run too many containers you just run out of space.
Some of the updates over the last year or so will put Google in a better position to increasingly put quality over popularity. There's still going to be a problem that people seem to trust Wikihow, etc...

Regarding the math problems: do you have an example of a query for which there's a good result on the internet, but Google doesn't return it?
It's sort of like extortion.
If they were putting the held-hostage chief of staff on the phone with Gulen, does that sound secular to you?
I don't believe NFS supports inotify events? At least, that's what I'm using, and I'm forced to use polling for any file change detection. And rsync is one-way IIRC. But yes, LXC on Linux works great when it's feasible; I've just been looking for something that supports file change detection on other platforms.
"If you can't explain it to a six year old, you don't understand it yourself."

This quote is attributed to both Feynman and Einstein. Both were very good in breaking down complexity into chunks digestible by mere humans. Ironically the author choose an Einstein image.

The arXiv, but instead of saying "published" or "not published" we put a score on the paper suggesting the probability one should believe its thesis.

Kinda like Rotten Tomatoes, but... for science?
Smile and upvote from me on this.
Well, if you think the most important technical improvement to language design discovered since the creation of Java in 1995 is some shorter syntax, go ahead. I guess.

Despite some very loud people on the internet, it seems to have close to zero adoption, and JetBrains making big promises and then failing to deliver anything is not really helping them.
I hear you. Perhaps I'm overly paranoid. I don't think so though!

Many people (eg. http://www.inc.com/larry-kim/5-online-privacy-tips-from-edwa...) have asked Google to clarify their policy in this regard, but the "generic" TOS you agreed to is the best they could come up with. The trouble with using soft language is that anything goes.

Data monetization goes way beyond serving relevant ads.

While companies like Sync.com encrypt your data end-to-end (making this a non-issue - shameless plug I know - you should check us out though), if you do continue to use Google Drive you may want to investigate third-party Google Drive encryption software such as https://www.boxcryptor.com/en (I hate to recommend a competitor, but it's better than nothing).

I'm making a strong statement, because I value my privacy.
I do appreciate a good bookstore. How much of my money i impulsively spent on animal covered volumes thinking they'd make me smarter I cannot be sure but it must be over a thousand. However they don't sell those anymore in my city.
Coding on the same platform that I deploy to has increased my productivity.
I didn't say it was not a problem, I said the headline was inaccurate and misleading, because it was, and that their other bad laws deserve more focus, because they do.

If they only outlawed things that deserved to be criminalized, like theft or fraud, would the VPN surcharge still be a problem? Contrast with the scenario where VPN usage does not increase your 1 million Dh fine for using Skype to 3 million.
Or "herbs". Americans say "erbs", approximating the French while the English say it like something owned by a guy named Herb.
If your complaint is not the message, but rather the phrasing, then I'd say that you're not being very charitable.
Working/studying abroad. I had many options when I was a student and right after graduation but for various reasons (esp. lack of confidence) I didn't seize the opportunity.

Cheaters are people.
You can have it both ways: use CloudFlare and offer direct access through a hidden service (since DDoS attacks over Tor are impossible, expect for application layer attacks).
What has been seen is reading of instruments which has been built according to some mathematical model to register conditions which supposed to happen according to bunch of theories and then a lot of calculations follows which presumably conform the assumptions according to the reading.

The simple analogy is pictures one has on fMRI. These pictures are, well, pictures based on approximations, not the mind. Not even close.

There is a paradox - one cannot make an instrument out of atoms to "see" what is going on inside these atoms. What they saw are pictures created out of mathematical models, not reality as it is.
It's unfortunate that the suggestions at the end don't seem to offer a realistic attack vector.

> First, scientists would need to be incentivized to perform replication studies, through recognition and career advancement. Second, a database of replication studies would need to be curated by the scientific community. Third, mathematical derivations of replication-based metrics would need to be developed and tested. Fourth, the new metrics would need to be integrated into the scientific process without disrupting its flow.

Yes, absolutely those things need to happen, but the problem is how to get this funded, how to get people to not see reproducing results as career suicide, right? Items 2-4 will fall out as soon as item #1 happens.

How do we make item #1 happen? What things could be done to make reproducing results actually an attractive activity to scientists?
I was going to recommend the Griffiths book as well. The first two chapters are readable without any demanding mathematics. The latter ones require more work, but build up nicely.
Using voip services like Skype is a crime. I would guess that is the main target of this law, since using VPNs to circumvent the present ban on such services is very common.
Run for the hills any time anyone says, "It's our in-house developed DSL!". It's a virtual guarantee that whatever was cooked up is some sort of insanity like JDSL.
If it's not capitalized (turned into an asset) then it's not an investment from an accounting perspective. Although R&D may be considered an investment by the layman, as the OP pointed out:

>even if it can be defined as investment in layman terms.
Python is so great for getting small tasks done in less than 30 lines of code that would take 5-10 times as much code in most other languages. I wish I had learned it earlier too. Still my favorite language to code without an IDE (C# is pretty great as long as you're in Visual Studio).
Honestly a lot of this should be on Greece.

They racked up huge debts while losing their competitiveness in the global market. This led to slower growth. Add in attempts to hide how much they were really in debt and you have a recipe for disaster.

This was compounded by the fact that since they relied on the Euro, they couldn't just print their way out this situation like the US does all the time. Instead, they got caught with their pants down and had no alternative but to own up and take severe measures to right the ship.
Westminster parliament is responding to the will of the people as expressed through the referendum. We shall what form the response takes over the next few months (Autumn statement will be a significant marker - there will be some economic data based on actual events then not sentiment or opinion surveys) and I'm sure the various political groupings will have plenty to say.

My point is that the debt transfer from private banks in predominantly Germany to the Greek state appears to have been a purely bureaucratic policy designed to prop up the Euro.

Disclaimer: I actually voted remain on the balance of practicalities.
The article is saying that having something explained to you by someone who's abstractions are closer to your level will be, in the default case, better than by someone who has more "advanced" abstractions. Additionally, great teachers are ones that can match abstraction levels with their students and slowly advance those abstractions as the student learns.

So, no it's not a fallacy, and yes the process of becoming an expert reduces the likelihood that someone will be a good teacher (of non experts).
I dunno....I don't find either to be necessarily creepy (although you can find creepy uses for just about anything I guess). Still, using a game to track your travels and location combined with the whole business aspect of an uptick in customers when you're a popular poke-location seems just as potentially creepy than the stuff that got people wailing and gnashing teeth over Glass - namely...a camera that you're always carrying around on your face.

I mean...miniature cameras are old news and they're a lot easier to hide in ways where people don't realize you have a camera. Just as there have always been ways to track stuff like location and purchases via cell phone location and credit card use.

The stuff in Pokemon isn't much "creepier" than what your average map app or social "gamifying" app like Foursquare does.
Huh, missed that and ‘past’ didn’t show anything up. Thanks.
While I agree with your sentiment, that's not what that comment says at all. It's about getting a copy of the data into the Internet Archive, regardless of what happens to gmane.org itself.
Why Developer Experience (DX) is critical while creating APIs for humans
All those dedicated agents, forgotten as soon as someone decided to slap cute cartoon characters and "training gyms" on our interdimensional portals...
The main goal of the paper was to explore a possible mechanism for the finding in a mouse model. The differences between Apollo and non-Apollo incidences of heart disease are ~technically~ significant, but look to be there more as motivation for the experiment than a conclusion in their own right--their analysis of astronauts in general vs. the rest of the US population is also new, and more interesting.
Syadmin horror stories
I'm a C# developer at the moment, but I use Python at work for pretty much anything regarding parsing or file manipulation that I need to do, or to hack out a quick proof of concept.
It's both. The phrasing contains a message of "these scientists didn't consider this obvious problem."
Accessing Netflix is not a crime, so using a VPN to access netflix would not be. If you used a VPN in a different country to access Netflix in order to circumvent their licensing restrictions, it probably becomes a complex matter of international copyright agreements. But that is already against the netflix terms of service no matter which country you are in, so complaints that you should be allowed to do that should be primarily directed at Netflix themselves, not the UAE.
> On the other side, someone born into wealth can be lazy, use drugs, and be a general screw up and still die wealthy.

Exactly. Paris Hilton and Lindsay Lohan are poster children for this.
Maybe this came up in the earlier comments, but... why are you calling w_0 + w_1·x_1 + w_2·x_2 + ... + w_n·x_n a "linear combination" of the x values? It isn't. (Nor is the constant term really a "weight".)
I read something about Thomas Pynchon the other day, so I borrowed one of his novels [from the library] and started reading. I spent about an hour and a half and went about 70 pages and it was clear why people regard his writing.

He's a very good writer and I didn't care about the story he was telling and I put it down and then took it back and I'm unlikely to pick up another of his novels. Ever. But I can appreciate why some people [including people I know] enjoy reading him.

Not judging a book by it's cover, isn't all it's cracked up to be because covers often reveal the author's name. What I appreciate about Altucher is that I know that there're going to be gems and going to be manure and the sense that he'd be the first to confess to the charge of producing a lot of manure along with the gems. What I know I'll get is not get an argument or a three point essay or an editorial.
