Looks interesting!

The link to your paper seems to be down: http://hci.stanford.edu/publications/empath-chi-2016.pdf



The closest equivalent I can think of is scikit-learn [1], which also gives you a unified way of using many different algorithms. I wouldn't say the two are really equivalent but both are excellent and a joy to use. One major difference is that, as far as I know, caret is mainly a standardization wrapper for other R packages' functionality, while scikit uses its own implementations.

I have become extremely weary of buying Microsoft hardware products. I was (and am) very happy with my Surface Pro 2. Recently, my power supply broke after two years of use, perfectly fine in my book, it happens. However, Microsoft has stopped selling replacement parts after less than three years. I did not find any vendor in Germany that could still deliver. I got lucky and found _one_ seller in the UK. There are some third party copies of the adapter, but due to the proprietary connector they are rare and reviews are abysmal.


For all the complaints about Apple dropping magsafe, I'm happy to finally have industry standard charging. Brick is easily replacable. Cable is easily replacable. Should work with any new computer, or even to cell phones and tablets (with a C to Lightning cable if you're an iPhone person).

Apple made a similar switch from one proprietary charging connector (magsafe 1) to another proprietary connector (magsafe 2) and it's a compatibility hassle between computers. For Surfaces it's an even bigger mess, because like you said, MS doesn't make them anymore. A coworker of mine had the same situation with a Surface Pro 1. Computer still works fine, but the power cord died, and good luck getting a replacement quickly. If you do find a 3rd party version, good luck with not burning your house down.


>> I'm happy to finally have industry standard charging.

Real question to people in the know - is this truly the case?

I get that the port is industry standard, but are there electrical protections put in place?

If I use a 100W non-Apple charger on a MacBook Pro that uses a 63W charger will it damage the battery? Will a USB-C phone charger (with presumably very low wattage) work as well (albeit slower)?

While I really like that TB/USB3 ports are standard, it is incredibly confusing to laypeople with respect to understanding all the nuances.


Apple's official note says "You should not connect any power supply that exceeds 100W, as it might damage your Mac." [1]

This is the maximum wattage allowed under the USB Power Delivery spec [2], so any USB-C power supply should work. Maximum voltage/current is negotiated between the supply, cable, and computer, which should select the highest amount supported by all parts of the system.

If you're using a cheap 3rd-party charger that doesn't follow the spec and decides it's going to tell the computer "I support 100W, let's do that!" and then jacks up the voltage beyond the USB power delivery limits, then yeah, expect to have problems.

The problem that I actually imagine happening is people getting a 20W rated cable with their cell phone, trying to power their computer through it, and wondering why the battery continues to drain.

Unfortunately, form factor (USB-C) is standardizing but internal wire connections/characteristic aren't, so we are going to an irrecognizable mess of cables looking the same way but some working, some not working and some bonus ones frying our machines.


Magsafe is also easily replaced with a BreakSafe power cable from Griffin: https://griffintechnology.com/us/breaksafe-magnetic-usb-c-po...


I'm transitioning all of my hardware over to charging on USB-C and it's great. Both my laptop (HP Chromebook 13") and phone (Nexus 6p) charge via USB-C, and I just went on my first trip in which I only had to bring a single, small charger. It's super convenient, and because it's becoming the de facto standard, I never have to worry about replacement chargers.

It'd be hard for me to buy anything that uses a proprietary charger ever again. This includes iPhones and Surface Books. And I've already committed to not buying anything that uses older versions of USB either -- it's all C for me.


Chargers on modern laptops don't seem to last as long. The cables are definitely "slimmer" and more prone to fraying/breaking.

My SP2 charger cable frayed near the power brick and I ended up just ripping the whole thing apart, cutting the cable & resoldering it. The enclosure was replaced with an off-the-shelf one. Looks ugly, but I didn't want to pay 100NZD for a third-party replacement.


I think Julias adoption is hindered by the lack of a real Julia-IDE aimed at data analysis. R has R-Studio, Python has Spyder, both of which are excellent nowadays. Julia has Juno in principle, but setup has never worked for me on multiple machines. The Julia language has a lot to offer, but there is no convenient way for people to give it a try that is comparable to what they have grown to expect from competing languages.


There's actually Jupyter. Then there's a julia backend for ess as well.

I'm using R regularly, and I couldn't care less for R-Studio. In our stat group, only 1 statistician out of 7 is using R-studio, while all of them are using R.

The IDE has very little to do with adoption.


There can be a difference between IDE choice among professionals and the role of an IDE in introducing people to the ecosystem. On ramps don't start at the target elevation.


For what I see, the first and foremost initiating factor for a statistical package is education, and second it's available methods/packages. You have universities where you can clearly see that the predominant taught package is Stata, or R (and in the latter, the choice of UI is mostly arbitrary).

In the end though, unless you want to reimplement methods, you can count on having R packages for any method you can think of.

Few statisticians though spend the time to evaluate different IDEs than what they where taught. I've "converted" many still using Rwin.


Try Juno (a Julia IDE on top of Atom): http://junolab.org/

I would not read this as questioning science but as the science-journalism equivalent of asking whether the 'mystery' can be 'solved' at all.


When a sentence is in form of 'Can X do/solve/manage/become/etc ... Y?' it is both simply asking and challenging X at the same time.

Challenging science is absurd as is challenging the reality.


"Can the president outrun a cheetah?" is not the same as challenging the president's qualifications as president.

It is challenging the idea that the president can outrun a cheetah, however. So, "Can science solve X?" is not the same as "Is science effective?".


I don't think that Apple has a PR problem regarding privacy when compared with Google. Especially looking at the privacy adverse stance Microsoft has taken with Windows 10, Apple seems like the smallest privacy evil out there. I personally will be switching back to iOS with my next phone after using Android for three phone generations.


The smallest privacy evil is still Linux. (Which, of course, is not an OS most people consider.)

Are you talking about MBAs or M.A./M.Sc. degrees in related fields? Personally, I do not even consider MBAs to be much of "a thing" in Germany. Yes, there are some prestigious universities offering them (St. Gallen comes to mind) but many people still have not moved on to the Bologna System from the good old "Diplombetriebswirt" in their hearts, let alone MBAs.


Especially Bachelor.

In my company we see Bachelors on the same level as people with just a "Ausbildung" in computer science. I also don't have a MBA or Bachelors and still got some job offers. It's just what you do. Actually in germany you can get a job really fast if you are into Scala / Java. Actually it won't make you rich, but it's good work and in Berlin there are a lot of companies searching for Scala Developers.


Just a remark: St. Gallen is in Switzerland, not in Germany


Could you elaborate why it is inaccurate?


For example Facebook explicitly does want to support job searches. (Babajob)


Facebook has a list of all current and future job search sites that anybody in India might want to use? What about job adverts that are just posted on the employers own website?

Unless you meant "Facebook wants to monopolise the entire Indian job search market with their own job search site while preventing people from accessing any competitors". That's more believable but hardly undermines the original quote.


Babajob is not Facebook's job search site (nor is the other job search site I just noticed on the list, Times Jobs). Only a couple things on the list of sites included in the program are Facebook's. Here is the list (as of a few months ago):

  Aaj Tak

Is Facebook being transparent about which of these websites are paying for inclusion in the free tier?



The quote says Facebook doesn't want poor people to be able to search for jobs. That is obviously wrong or else they wouldn't provide job search. You may believe they want to monopolize job search, but that is not what the guy said. And show me an example of a job site that want allowed on their platform.


Helping the poor is a red herring. Facebook could easily give fair, unbiased acccess, but they want a monopoly.

Would you be so apologetic if Comcast gave everyone free NBC streaming but charged more for Netflix?


How could Facebook give everyone unfettered access? Wouldn't that involve paying for everyone's data plan?


The amount of money they used for lobbying and andverts was enough for them to pay for actual costs of internet packs if they worked with carriers on that


By not using a man-in-the-middle vulnerable proxy and giving fair and unbiased access to all websites.

Who said they would be paying for everyone's data access?


I had the same feeling, the website doesn't look ... done. However, I think it is nice to see that MS is launching its own initiative. The more, the marrier. I'm especially interested to see how their LDA variant performs.

Still, I hope they continue to make the documentation a bit more accessible. In example, the LightLDA documentation (http://www.dmtk.io/lightlda.html) gives no indication of the output I would get from this. Do I get all the matrices (word to topic, topic to doc) or just a list of top topics, or...?
