I mean, duh. They basically have a monopoly and a license to print money right now. they can't make the same profit margins they have been if they have to compete with local municipal providers who aren't based on a profit model unless those local providers are so incompetent that they can't deliver reliable fast internet to their area. Comcast can't do price hikes and data caps and generally continue treating their customers like abused spouses if there is an equally attractive alternative which doesn't have an incentive to nickle and dime you to death. If I could get municipal fiber, why would I pay comcast more for less? Comcast would need to completely reevaluate their business model from their abusive "but who are you going to turn to?" monopoly to a competitive service with a eye towards meeting customer expectations for reliability and service. In other words, comcast will have to spend a fair amount of their massive profits on things like service upgrades and customer relations.

And really, as a monopoly comcast should be busted up.
So are you saying the abortions cost too much?
The situation is probably less immediately dire than the numbers would suggest - most graduates of science programs at second-tier colleges chose their program with the goal of getting into a medicine or allied healthcare program, these are graduate degrees in the US.

That said, it's a mess. These undergraduate programs tend to teach to the test, the curriculum has little relevance to what shows up in the nursing program, and when there is a conflict between learning and GPA the GPA always wins.

And then there's the added student debt and missing earnings from the undergraduate program. Some universities have instituted BA/MD joint-degree seven-year programs. These are the future, change can't come soon enough.
And yet, we keep hearing about a shortage of developers.

When you have a real or de-facto monopoly you just assume you can get away with poor/overpriced service. Most corporate bean counters making such decisions don't take into account the second-order effects you describe, until they materialize into a real problem.
That's only valid if the known bots are a random sample of all bots.

They can't test against a large array of public bots because they're only detecting political bots, not everything automated. So they'd have to train/test on "accounts which are definitely known to be bots, but trying to hide it". Meaning, presumably, the least-convincing bots or bots specific to a previously-exposed network.

Paint.net is another example of an application that reifies its actions with a nice 'history' window that shows the semantic actions that the user has performed and allows you to jump back to earlier points in your history of editing the file. GIMP does something similar, it seems particularly common in image editing programs.
???

All of the software you mention has had, over the versions, introductions of major bugs, regressions, UI elements changing for the sake of it, features available in a previous version being removed in a subsequent version (sometimes to be reintroduced later)...

I'm not sure if that's a rhetorical question or not, but the hospital is trying to ensure they don't waste a liver. Not enough people donate their organs, so these really are precious resources. My assumption is they have a one year waiting requirement to ensure the patient doesn't wind up homeless again. Maintaining financial stability is tough. That said you'd think they'd be able to coordinate with the local shelters and housing organizations to work this all out, but my assumption is there's not enough budget for social workers that would do this.

Having false positives are quite serious though, especially when it comes to shutting accounts down at scale. Sure it works on their small sample test runs, but anyone who's applied these algorithms in real life in an automated fashion understand the risks of false positives is usually far higher in practice.

You will basically be put at risk for following 'controversial' accounts on Twitter of having your account delete accidentally. And businesses will have to jump through bureaucratic hoops to use legitimate automated scripts to manage accounts.

It also seriously deters anonymous online speech if they force a big percentage of users to provide a unique phone number to prove they aren't a bot (the current Twitter strategy for countering spam). Not to mention the liberal sharing of information with nation states, surreptitiously or otherwise, even for people not trying to be anonymous. A phone number is a critical identifier in the surveillance industry.

Getting this accurate is very important and I feel like that is being heavily downplayed in this article.

You don't even need an adversarial attack method to fingerprint or watermark a proprietary dataset. If the dataset consists of images, you could just watermark them, or mark them using steganography. The watermark would appear as random (non-targeted) noise, and would be mostly invisible to current classifiers. Please note that the noise employed by adversarial attacks is very different, it is highly targeted.
Landing pages make this very same mistake all the time.

It is one of the biggest goals for such a page, to show the what & why of the product, and still too many people do it in a way that lets no clue about what the thing is about.

It is good to see other people noticing this and writing about it. Hopefully this will be included in good/bad practices lists in the future.
I grew up watching those X-Men cartoons and the equally good (as I recall) Spider-Man seasons that followed too.

The browser?

Though as you mention, many developers nowadays don't see the need for history, and so are putting application/webpage state somewhere other than the router. This IMO is short-sighted, as it undermines the transparency of a user's actions on the web. And plays into the walled-garden effect many of these same developers will lament in the loss of the "open web".
Rule of thumb: If you find a blatantly obvious solution and you're not an expert in the field, assume people who are have thought of it and discarded it - or it would exist.

(Note: I'm not an expert in the field, either. But the above rule works most of the time :)
I don't really think you can say that. Labor is not a perfect market.
What's the realistic approach to this though? I don't know anything about this area, but to me it seems like hoping for 20 countries having 50 each would be effectively the same as hoping for 20 countries having 0 each.

That is to say, we're in the arms race because each country did have N each. But then one country had N+1, and so the others raced for N+2, and so on. If we hoped for 50 each, wouldn't it drop back to the same pattern, and someone would become 50+1?

Note that 4,000 of course doesn't solve the N+1 issue, but my point is if you're going to aim for 50 - I'm not sure what problems it solves. May as well shoot for 0, no? 0 seems equally impossible to me as 50, but at least it solves a single problem.. nukes, in general.

It doesn't HAVE to be super political, there are municipal water, sewer, electric, and gas utilities all over the country and they are very rarely politicized. If you consider broadband a basic need (I do) then it makes sense for it to be provided by the community just like those other utilities.
If the warhead had damaged the fuel tank there would have been an explosion, and the radioactive materials in the bomb would have been spread around the site. It would have looked like the Palomares explosion, and that was a mess: https://en.wikipedia.org/wiki/1966_Palomares_B-52_crash

There was an incident (this one: https://en.wikipedia.org/wiki/1980_Damascus_Titan_missile_ex...) when a serviceman dropped a spanner while working on a missile. There was a fuel leak and an explosion, thankfully the warhead was thrown clear of the silo by the blast.
> I'd rather live in a world where 20 countries have 50 warheads each, then one where two countries have 4,000 warheads each.

I absolutely would not. Those 2 countries know far more about the process then those other countries, and they have the budget to do it right. You would have to duplicate labs, and computers, and other efforts 20 times in your scenario, and each of those labs will not be as good as the 2 higher funded ones.

> A weapon detonating by accident is terrible. Thousands of weapons on hair-trigger alert is civilization-ending.

Look at it from a fear point of view: No one will detonate a thousand weapons unless they are declaring total war. So all one needs to do is read global moods and see if total war is likely (it's not). (i.e. war might happen, but not total war)

An accident on the other hand can happen randomly, you would be permanently and constantly worried about one.

From personal experience, many users fear all UIs. This because they fear that their actions will be irreversible more than anything else.

And frankly i suspect that CLI gets a bad rep because MacOS never had a CLI to begin with (OSX got one via its unix internals, but i am unsure Apple knew to value it), and DOS was minimalist to put it mildly.

Sadly this has lead to unix UI devs to disparage the CLI when they should embrace it. That a X11 GUI tool is a wrapper around CLI tools is not a hindrance but a boon.

It means that if the CLI tool behaves correctly, the GUI tool will as well. And if the GUI tool behaves incorrectly, the user can try the same in the CLI to see where the problem originates.

It is really sad to see the push towards using dbus rather than CLI to communicate between GUI and daemon, as so much potential information is obscured in the protocol.

Insulated tools won't prevent a short from a metal tipped tool. The operator should have used a plastic fuse puller.
Agreed. I have a foot in both camps myself.

But there are two issues: FT8 is just a contact, with maybe a 73, so it’s even more impersonal than contesting (which is extremely popular, of course). Breaking a pileup is pretty much left to the computer, rather than due to operator skill.

And the old timers on 160 who earned their DXCC (100 countries - very difficult on 160) certificates the hard way using CW / SSB aren’t happy with the relative ease of getting an FT8 DXCC award. The ARRL can fix that, however.
OP here. If you haven't seen this paper before, take a look at Tables I and II, which show two simple, discrete, probability distributions for three variables, each of which consists of two bits (i.e., each variable can take four possible values, 00, 01, 10, and 11). In each distribution, the three variables depend on each other.

The distributions are different, but if you take a look at figures 1, 2, and 3, you will see that their Shannon Entropy diagrams are the same, and that a directed acyclic graph cannot represent either distribution.

Let me repeat that: today (1) there is no consistent way to measure the information of the three variables in these toy distributions, and (2) no Bayesian model can measure their dependencies. In short, probability theory cannot cope with these toy distributions.

Wow.
I don't like it when people sell renewable sources of energy as "the cheapest source of energy available". If it were actually cheap then why do you need a community funded project? The problem with solar is storage but hardly anyone discusses that in the total cost of energy consumption.

These projects need to be transparent up front. To achieve the "cheap" objective you need benchmarks such as existing technology vs future technology. For instance, i believe they should state "our goal is to achieve $X/Kwh compared to $Y/Kwh of existing technology". That way you can see something measurable, scientific, and objective oriented.

I like the project so don't get me wrong. I just think they've worded it all wrong as what they are trying to achieve.
There was an interesting article "Nothing is cheaper than proof of work"[1] that talked about both proof-of-stake and using miners to heat your home. Basically, if you decide you are willing to pay $9 to make $10 back, then discover you are additionally saving $1 off your heating bill, you will logically be willing to pay up to $10 to make $10 back + $1 in savings.

But, the main point of the article was that "proof of stake" is basically selling liquidity (exactly like bonds) and, to get the same job done, the cost of that liquidity won't end up being any cheaper than the cost of the electricity it's replacing.

But this is wrong. It's not an externality for the company. Companies often often go out of their way to reduce this cost. Things like:

- Covering the cost of a FastPass

- Deciding where to locate a new office based on where employees live

- Offering a company shuttle from a train station

- "Google Bus" and other similar initiatives

- Offering a potential employee a higher salary because of their long commute time

These things happen all the time, and all bring a portion of the commute cost into the company.
At which point they choose lobbying to double down on monopolyship over caring.

Possibly, but public private partnerships have a long and storied history of ripping off the taxpayers and government.

For example, take toll road highways. Not a single one exists in the USA that lasted the length of their contract without going bankrupt and ripping off everyone.

>Beginning with the contracting stage, the evidence suggests toll operating public private partnerships are transportation shell companies for international financiers and contractors who blueprint future bankruptcies. Because Uncle Sam generally guarantees the bonds – by far the largest chunk of “private” money – if and when the private toll road or tunnel partner goes bankrupt, taxpayers are forced to pay off the bonds while absorbing all loans the state and federal governments gave the private shell company and any accumulated depreciation. Yet the shell company’s parent firms get to keep years of actual toll income, on top of millions in design-build cost overruns….

>Of course, no executive comes forward and says, “We’re planning to go bankrupt,” but an analysis of the data is shocking. There do not appear to be any American private toll firms still in operation under the same management 15 years after construction closed. The original toll firms seem consistently to have gone bankrupt or “zeroed their assets” and walked away, leaving taxpayers a highway now needing repair and having to pay off the bonds and absorb the loans and the depreciation.

>The list of bankrupt firms is staggering, from Virginia’s Pocahontas Parkway to Presidio Parkway in San Francisco to Canada’s “Sea to Sky Highway” to Orange County’s Riverside Freeway to Detroit’s Windsor Tunnel to Brisbane, Australia’s Airport Link to South Carolina’s Connector 2000 to San Diego’s South Bay Expressway to Austin’s Cintra SH 130 to a couple dozen other toll facilities.

>We cannot find any American private toll companies, furthermore, meeting their pre-construction traffic projections. Even those shell companies not in bankruptcy court usually produce half the income they projected to bondholders and federal and state officials prior to construction.

JS is single-threaded by design and node encourages use of asynchronous operations and then runs callbacks on the event loop. Node provides higher-level non-blocking function spawn, so closh currently does not need to do forking directly. I hope this can get us far before the need to drop into lower level and start dealing with threads.

I am curious, what does fish use threads for and how does it handle them?
Tried a few basic things, some of them did not work:

1. x = rnorm(1000)
2. plot(density(x)) --> not work
3. stem(x) --> not work
4. summary(x) --> works

For R data handling, I always use data.table for its efficiency and power.

1. library(data.table)
2. x = data.table(x=rnorm(1000)) --> not work
> x = data.table(x=rnorm(1000))

> If it's exactly reproducible on different hardware and software configurations, as seems to be one of the goals, that alone would be a useful improvement on IEEE754.

IEEE754 already supports that (except for the minor fact that the NaN types can in theory be represented by different bit sequences - in practise all the same are used). The problem rather is that typical programming languages (such as C, C++) have no proper support for IEEE754.

And you have to be very precise in your intentions: For each of the operations defined in IEEE754 you have to define which of the four (+ one optional one in the 2008 revision) rounding modes is to be used. Or you have to be precise whether a MAC or and multiply (then round) and add (then round again) is to be used. This of course has again implications that depending on what the compiler makes out of it either the program will not run on processors with no MAC support or the code has to use a software emulation (slow).
