Some care. I don't think it'll ever be "mainstream". But I certainly care. I switched from Arch to Gentoo and systemd was one of the reasons.

And no, I don't really expect Gentoo to be something most people use. But to me that's the beauty of open source. If someone, or a group of people care enough, they can make it happen, if someone else finds it useful too doesn't necessarily matter.
So what you're saying is that a business can not negatively impact the society it exists in in any way, so shut the hell up with your criticism?

No, that is the 55,000,000.00 question.
The U.S. middle class pay fairly low taxes but they also get a fairly low level of government services. The cradle to grave system in a country like Germany simply doesn't exist here.

It isn't really our total spending that's out of line, between local, state, and federal government expenditures are comparable, if on the low side, to Western Europe rather it's: 1) we spend wildly disproportionate portions of our budget and economy on the military and 2) we spend a lot more on health and education with less comprehensive coverage and without getting unequivocally better results where we do cover.

Finally, within the middle class, which can be a very broad term, there are big differences. Our tax codes are riddled with distortions designed to further this or that policy goal, as well as varying by geographical region because of our federal system. Two taxpayers with very similar total income and assets can end up paying very different amounts.

The article does point out how easy is it is make profits appear as though they were earned offshore however.
I was expecting to read about some experiments with autoencoders here, not this tutorial. I'm not sure how the author is learning about neural nets or where they are now, but anyone at this level of knowledge who wants to know more would be well served by going through Geoff Hinton's class on Coursera.

Do you have really big fingers?
From the article:

> But the fact that grains posed a security risk may have been a blessing in disguise. The economists believe that societies cultivating crops like wheat and barley may have experienced extra pressure to protect their harvests, galvanizing the creation of warrior classes and the development of complex hierarchies and taxation schemes.

How is that a blessing? Sounds more like a curse.
It's good to see people write up their experiments, it's useful for the rest of us to test how we understand neural nets.

I think there are a few mistake in your maths though. You can learn a 1-1 discrete mapping through a single node where you are using a one-hot vector. You just assign a weight to each of the input nodes, and then use a delta function on the other side. If I understood correctly, this is what you are doing.

Also, if you use a tanh in your input layer, but keep a linear output layer (as you start off with), you are still doing a linear approximation because you have a rank H (where H is the hidden layer) matrix that is trying to linearly approximate your input data. This is done optimally using PCA.

I'd second the advice to look into the coursera courses, or the nando de freitas oxford course on youtube (that actually has a really nice derivation of backprop).

I am not against them considering the end users. But getting pushed around by "end-user" (please read desktop-user) focus is way too unacceptable behavior, especially for a community like Debian.

Dispatchable wind via compressed air storage seems to be quite a thing in the scientific community. Unfortunately, big subsidy schemes like the german one fail to acknowledge the importance of dispatchability, so they utterly disincentivize any development in that direction.
If you make the choice to interact with the US' economy you implicty agree to give the US a cut for its role in the creation and tending of that economy.
It also cause pressure waves in the exhaust system since you're using the vacuum forming in the engine to slow you down, which is more noticable at low rpms due to the slowing of the positive exhaust pressure changing to intake vacuum frequency. Going from acceleration to engine braking at low rpms, such as in traffic jams, has caused a weaken seam in my exhaust system to break.

> Geocities was shuttered before "young people" today started using the Internet (and was dying for years before that).

Yeah. Because young people in 2005 are now like 20 to 30 somethings today. That was 11 years ago man. A 35 year old today who was really into Geocities back in its prime was a 24-year old young person (although Geocities prime was really closer to early 2001 or 2002).

In any case, I fondly remember the awful Neopet communities with awful gifs and everything that I used to browse on Geocities. Anyone remember "Webrings" ??

Now I admit, 2005ish was when Xanga and MySpace started to take over (Facebook was a "college" thing, and not really relevant to high-schoolers at that time). But Geocities was still relevant at that time.

Imagine once VR/AR become mainstream. You'd have real artists having simul-cencerts in ten stadiums (or in homes for the homebodies) competing against anime performers who don't get exhausted or get sick or who want to retire... So the farce of the "artist" can be all done with --just corporate manufactured music entertainment.
Org mode is a tool. It's got a formatting language in it, but it provides calendar, schedule, time tracking, workflow management, and more.
Don't forget about 12.4% social security and 2.9% Medicare payroll taxes.
In another comment thread on Taskwarrior, someone more intelligent than me suggested just using plain dirs and files, one file per task. Then you get all of Unix for free, with any metadata you want as part of the filename or contents. I'm a former org-mode user who now just uses a paper book, but if I still wanted to use a computer, dirs+files would be hard to beat. One or more folders for todo, one or more folders for done, stick it all in Dropbox.
If you're implying that TaskWarrior is a tool and that org-mode is a formatting language (or file format), then you're way off to begin with. Org-mode does have a specific format for its files. But much of its power derives from the tools it incorporates. E.g., the org-mode Agenda functionality enables complex searches over multiple files and collects and orders the results in a single buffer, and allows users to perform operations on the results (i.e., on the original buffers containing the results) directly from the Agenda buffer. There's much, much, more. Org-mode is primarily a tool, not a file format. If you want an overview of some of its functionality, you can take a look here:

The Army has indicated repeatedly that it is willing to bear the support burden for tasks that are important to it.

For example, the Caribou and more recently the C-27 light transports that were taken from them and reallocated.

In 1960s the US Army was investigating organic fast-moving CAS aircraft, they tested the F-5A, G.91 and A-4 but were told that it was unacceptable. They even faced restrictions on arming the OV-1 Mohawk for which they paid every cent.

They want it, they will pay for it but the blue-suits have the document that says 'no'.
Incorrect, most of us just like to build stuff. The money is a nice perk to continue building even more stuff.

Rayiner's post has numbers that are made up. Here are actual numbers from University of California economist Emmanuel Saez:

https://eml.berkeley.edu/~saez/lecture_saez_chicago14.pdf

The top 10% have 50% of the income, and the top 1% have 22% of it.
Your source doesn't support your claim - it doesn't compare effective tax rates of the top 400 taxpayers at all.

A quick google search finds this graph which refutes your claim:

http://www.pgpf.org/sites/default/files/2014_tax_explainer_c...

http://www.pgpf.org/budget-basics/how-much-do-americans-pay-...

Note also that this source includes corporate, estate and payroll taxes as well as income taxes, while your source looks only at income taxes. The top 0.1% pay 35.7% effective tax rate, the top 10% to the top 5% pay 20.3%, and the bottom 10% pay 3.1%.

> Would programmer type B want to work with a 2 year old project from another type B programmer?

Sure!

A homegrown javascript ecosystem doesn't grow up in a vacuum. It may include smaller libraries that aren't as opinionated as this year's popular framework. It may draw inspiration from Backbone or Flux without using either outright. And it should follow familiar design patterns.

In fact, some frameworks start out this way (https://ampersandjs.com/).

Now, the answer you probably expected was "I'd want to see it first." And that's true, but that's also true with a framework. The things that make a project pleasant to work on - good architecture, docs, clarity - aren't guaranteed with a framework.
I'm sure with perturbation analysis you could also remove even more edges from the ANN.
It's too early to do that. Researchers are trying to study whether the primitives are going to work --- ie, that the new hard problems they're based on will hold up against quantum speedups and that they're secure against conventional adversaries. Simple DH is a straightforward backdrop for that problem. Composing DH into an AKE doesn't much help, as long as the primitive is flexible enough.
Spot on. People complain that the F-35 is overkill for brushfire CAS missions, but what they miss is that the A-10 is overkill too.

A weaponized T-6 crew with an observer and modern ISR would have way better situational awareness than a hog driver will ever get. A turboprop would also be able to spend far more time in loiter due to the low speed efficiencies of a large prop versus a small fan.

But the AF wouldn't play ball in that game. Let the Army fly fixed wing aircraft and a practical CAS solution for interminable brushfire conflict would be implemented pretty fast I think.
More and more universities are paying for 'gold' (open) access publication. They're beginning to realise that you get more citations if people can actually read your papers without needing to go through the paywall.

One of the advantages of publication is peer review. When you cite someone's work, if it's in a reputable journal then you can assume that someone reviewed it and would vouch for the quality of the research. You have to take it with a pinch of salt (reviewers are never totally unbiased and they make mistakes), but in fields where research is easy to verify like computer science, a publication in somewhere like Pattern Recognition holds a lot of weight.

If you just cite a random paper that someone's self published on arXiv, you have no real idea whether what's being presented is true. Again, this isn't so much of a problem for CS papers where you can implement and test the work yourself, but for fields like physics where you're relying on other people's data, you want to be sure that someone smarter than you checked the numbers.

I had a similar experience with Facebook although I did well until the last one. Then I was just too tired and hadn't practiced enough to do a good job. After the fact, I read more of the interview questions on Glassdoor and wished I'd read them before and practiced those on a whiteboard at home.

So that is what I'll do next time I want to interview at FB. Overall, I really enjoyed the process as an interviewee. I've been on both sides and I'm curious how well the other side is done at FB but I left with a good impression and thought the outcome was fair.

Also bonus points to them for asking real world questions. I was asked about making a web-based text editor and a couple months later, Draft.js came out.

Even with competent computer owners it's a problem. Bruce Schneier once pointed out that, given how much money is spent on presidential elections, we should assume that election hackers have budgets of $100 million. They could easily pay for zero-days.

It's not even out of the question that organizations like the NSA could launch attacks, or their counterparts in other countries.

It's also a problem for electronic voting machines without paper trails. One researcher several years ago demonstrated a way to make a virus attacking a popular voting machine. Without a way to audit the results, there's no way to know whether this has happened.

Rayiners numbers come directly from income tax returns, which you'd know if you read his source. Where do Saez' numbers come from?

He's certainly doing something nonstandard. From his slides: Caveats: Income concept used is narrower than National Income and focus is solely on pre-tax, pre-transfer income

I'm guessing Rayiner's numbers include taxable wealth transfers while Saez excludes them, but I'm not really sure.
> The roaming issue comes from roaming info usually being small footnotes, most consumers not thinking about the subject (and not considering they'd need it )

Then the EU should set standards for roaming advertising and contracts, not dictate the price.

I can't think of any other domain of business where a Western national or supra-national government set privte-sector prices because customers can't be trusted to read T&Cs.

Car rental contracts often have horrific small-print penalties for crossing intra-European state boundaries, but I don't see the EU intervening there.

Just by way of example, I've used .note sections in the past as a place to store such mundane things as checksum of the binary text segment, so that text-segment verification can occur before the binary is loaded (for safety-critical systems) .. its quite a useful section, as long as you know what you're looking for..
Ditto the first part. I have a .service file for haproxy, one for my node app, one for rethinkdb, they generally just work.

I understand people that dislike monoliths, but I also appreciate the DRY nature of systemd - the System V, bash, cron, at, various process monitors, syslog combo was a lot of code with a lot of overlap. I'd expect systemd is actually smaller in LoC that what it replaced.

I think some of his statements are a little off-base, for instance, regarding the choice of tanh() for the activation function he says: "But mostly it’s 'because it works like this and it doesn’t work when we change it.'"
People have spent a fair amount of time investigating the properties of different activation functions, and my understanding is that tanh() is generally not in favor, and ReLU (rectified linear) is probably a better choice for many applications, for reasons that are well understood. Maybe the author isn't all that familiar with the field?

Now that would be an interesting stat... So they collect $7 trillion a year, but to collect 1% more ($70B) we would have to pay them 1/4th of that, or $17.5B -- an additional 150% of their current budget.

Hardly seems worth it, aside from the satisfaction of holding all those tax cheats feet to the fire.

Ask HN: Battery Research with an Open Science Community, Does It Exist?
Increased energy density while cutting marginal costs is a hard problem with significant payoffs. Breakthroughs would unlock new business models and welfare effects from robotics, transportation, disaster relief and feasibility of carbon neutral energy production. However, research in this domain with but a few examples [1] is characterized by proprietary R&D.

On the contrary, we've seen great collective achievements over the last years in a variety of fields:

- gitxiv.org, arxiv.org: Various CS subdomains, math, physics
- gym.openai.org: Reinforcement learning
- www.fold.it: Protein modelling

The list goes on and is accompanied by controversial but factual initiatives towards public research becoming free as in FOSS [2]. According to Franzoni & Sauermann (2014) [3], the main criteria for effective open science communities are:

- sharing of intermediate results
- openness to participation

The ideal platform would thus be effective in breaking down problems to crowd-scientists and enable attribution of teams and individuals (better than on a subreddit). This post is both a question and proposal towards evangelists who would like to join such a project.

Are there any open online communities for battery research? If not, what are communities closest to the domain and potentially receptive? Which journals publish work that is ahead or on par with closed R&D?
