I use Gollum, which uses git for its database and it’s the same wiki GitHub uses.
I use it, or used it. It supports Markdown editing, creation/editing in wiki, file upload (well, I’m 90%).

Most readers will be familiar with -x = ~x + 1 = ~(x - 1).
Ah. I thought that said “–x = –x+1” instead of “–x = ~x + 1”.

So, Jeffery Tucker may indeed be the sort of zealot who can blithely reduce all human values to the relative pricing of goods and services. He may even be wrong. But this little rant does a lousy job of presenting a counter-argument. If there’s ever really any evidence that ISPs are conspiring to censor or manipulate traffic content, won’t we just see increased consumer VPN use? And if they’re not conspiring, wouldn’t competition work against any individual would-be ISP censor? What exactly do we suppose they stand to gain by doing that, anyway?
If we want to get upset about censorship and manipulation, we should be talking about Facebook and Google, not Comcast and Verizon. In my world anyway, what sucks about the latter pair (both before and after 2015) is their shitty service, bandwidth caps, and too-high prices.
I probably shouldn’t fan the flames… but here are a couple of counter-counter-argument pieces I find much more convincing, despite their tinge of economic absolutism:
-
I agree that platform providers are more directly interfering with speech. (e.g., Google’s Content ID system interferes with fair use on YouTube.)
However, we do have evidence of ISPs manipulating traffic in favor of their own preferred content and services, cf. https://www.freepress.net/blog/2017/04/25/net-neutrality-violations-brief-history
From the perspective of the FCC, Net Neutrality is about classifying ISPs as common carriers. Currently, ISPs like Comcast provide a bundle of services and Title II prevents them from giving priority to, say, their own video-on-demand service over Netflix.
-
And if they’re not conspiring, wouldn’t competition work against any individual would-be ISP censor?
There is hardly competition. If you have two choices, consider yourself lucky because as of June 2015, only 24% had two broadband ISPs. As of June 2016, FCC reports showed three-quarters of the US still lacked high-speed broadband choice.
-
we should be talking about Facebook and Google
Huh, I never considered that angle. They do control the content we see in a much more obvious way.
Also, this article tries to ignore the cost of providing the internet and make it on principle. An article with cold hard numbers (not airy ideals) is an interview with Ajit Pai at http://reason.com/blog/2017/11/21/ajit-pai-net-neutrality-podcast

Those whose sensibilities are offended by “airy ideals” are welcome to dive down into the nitty gritty of why Ajit Pai is basically one of the most dishonest people there is in this “debate”.

ignore the cost of providing the internet
U-Haul charges you $n/day, which covers the cost of providing the truck. U-Haul doesn’t charge you more if you fill the truck with your massive MGM DVD collection than if you fill it with furniture. Once you pay for your 402 cubic feet, the capacity is yours to use as you please.
ISPs charge you to access the internet, which covers their cost of providing the internet. ISPs charge Netflix to access the internet, which also covers their cost of providing the internet. Once you and Netflix pay for your GBs, the capacity should be yours to use as you please.
However, the ISPs decided they wanted to charge Netflix for your wanting to access Netflix on the internet which you and Netflix had already paid for. Netflix didn’t want to, so ISPs blocked/throttled access to Netflix… until Netflix paid to stop the bleeding. Net Neutrality stops that bullshit.

Exceptional. I’m a PhD student.
-
-
When I was a mere undergrad writing my honors thesis, my work-life balance was without the slightest doubt abhorrent. Every waking moment, and many sleeping ones, were devoted to it. One imagines a doctoral dissertation to be even more extreme, though I suppose the increased scale and scope limits the maximum possible intensity.
Of course, the upside to a thesis (as opposed to a job) is that it has an end date, and once I slept off the hangover from getting incredibly smashed after the submission deadline, I got to enjoy a month and a half of effective vacation before graduation.
-
My point in stating my “exceptional” is that it is possible. I did work a few Saturdays on my thesis, but in comparison to the years it took, they were to rare to drop to “average”. It is possible to get a PhD working 9 to 5. If you are a PhD student under a culture of intense pressure, let me tell you that it does not have to be that way.

“In addition, Pytorch is quickly developing popularity amongst top AI researchers. Torch users, although nursing RSI injuries from writing Lua code to perform simple string operations, simply aren’t deserting in droves to Tensorflow – they are switching to Pytorch.”

Here’s a citation. The CAT bytecode operation and table.concat are JIT compiled in LuaJIT 2.1, which is the version Torch uses by default.
So, either these people are using a 2+ year old version of LuaJIT, or their code is bad.

If x is a global optimum for f, then grad(f, x)=0. I use this to test; it doesn’t require the implementation of f.

This almost fits my use case. I’m not so interested in interactive documents, but interactive widgets. A good example is http://stsievert.com/blog/2015/12/09/inverse-part-2/
This relies on ipywidgets-unsupported, but there’s interesting work with jupyter/ipywidgets. In the 6.1 release they’ll support the same thing as above with easy generation!

I work in ML, and this case is common. But the other case (“after some time thinking and reformulating, this problem is simple”) is also common.

I Had All of My Electronics Seized by U.S. Customs and Border Protection
Sorry this happened. As a US resident, I didn’t realize how crazy it can be entering or leaving the United States until I did so for the first time. The US was by far the hardest country to get into for me (even though I’m a citizen). It’s a shame that interactions with customs is such a mixed bag, and I worry that it is actually going to get worse for the time being.

New MacBook Pros Fail to Earn Consumer Reports Recommendation
I’m honestly really curious as to what the problem is here. It clearly escaped internal testing, but even more interestingly it’s nondeterministic! Laptops with terrible battery life are a dime a dozen, but how often do you get a device with bad battery life sometimes, but great the rest of the time? Not even “some units have bad battery life” or “the device has bad battery life when doing X”.
The symptoms are bizarre enough that there’s got to be some interesting bug behind it all.

John Gruber
Once our official testing was done, we experimented by conducting the same battery tests using a Chrome browser, rather than Safari. For this exercise, we ran two trials on each of the laptops, and found battery life to be consistently high on all six runs. That’s not enough data for us to draw a conclusion, and in any case a test using Chrome wouldn’t affect our ratings, since we only use the default browser to calculate our scores for all laptops. But it’s something that a MacBook Pro owner might choose to try.
This is crazy too. Whatever the benefits of Chrome are, everyone knows it’s an energy hog. There is no way that using Chrome should result in better (and more consistent) battery life than Safari.
I would want to see more complete tests.

Why does this work?
The graph is the colored directed graph with vertices
0, 1, 2, 3, 4, 5, 6and the following rules0, all others are blackkto(k+1)%7kto(10*k)%7So each vertex has two outgoing arrows, one black, one white.
If you know the remainder of
nmodulo7, this graph allows you to read off the remainders ofn+1and10*nby following the black and white arrows emanating from the vertexn%7. An integer is divisible if and only if its remainder modulo7is0.In the example given on the page, you calculate the remainder of
325as follows:325 = ((3 *10 + 2) *10 + 5 = ((0+1+1+1) *10 +1+1) *10 +1+1+1+1+1.Start on the white vertex, follow three times a black arrow, then once a white arrow, twice a black arrow, once a white arrow then five times a black arrow and you land on vertex
3 = 325%7.What makes 7 special? Could I construct a similar graph for 5 or 11?
There’s nothing special about 7 here. Except that it’s the first number for which all divisibility tests in base 10 are kinda tricky, so it’s neat that you can visualize one such test in a planar graph.
You can define similar graphs
G(b,m)for every baseb>=2and every modulusm>=1: the set of vertices is{0,...,m-1}andkis connected to(k+1)%mand(b*k)%mfor each vertexk. Thus, the graph in the post isG(10,7).The author lists the planar graphs for small values of
