"s it just me, or does even the 'bargain' price of $647/enrollment from the federal website... seem surprisingly bizarrely high? (by an order of magnitude or more)?"

Welcome to government contracting. The few who play the game basically get away with whatever they want. It is quite ridiculous.

The cost is only going up now that states are essentially pot committed. After the initial disastrous implementations across the board I doubt anyone is in a hurry to try that again.

I have the original CA proposal. $360,334,374.00. I’m sure there is at least another $50,000,000 in contract mods. The waste is just unreal. Creating local jobs? Not tech ones. The site was done in India.

Something like this sounds like a very good use case or AWS or another cloud service given the enrollment periods. Of course there is no profit in that. From their proposal:

“As discussed in Section 2.5.1 Hosting, we plan to implement a Private Cloud type infrastructure for CalHEERS. Why Private Cloud? Since standard cloud offerings, available from Amazon, Verizon, and a number of other service providers, offer sufficient capacity and are immediately available, they may seem like a good answer. However, standard enterprise-level cloud-based solutions currently focus on commoditized functions such as ERP, CRM and to a lesser extent HR and payroll. While SLAs are offered for security and availability, they do not meet the Exchange’s requirements for secure, SLA-based data intensive operations”.

The solution? 1,714 cores, 9,394GB of RAM, 392,327GB of Storage over 249 virtual machines. Every single piece of software is Oracle with the exception of Adobe LiveCycle.

Even with an average billing rate of $150/hr, more processing power then most Top 100 sites on the Internet…. they couldn’t keep a fail whale page online let alone any functionality.

Once it is finally somewhat usable they are treated like a raving success and awarding with… the federal contract.

Quite a business.
Why is it so commonly glossed over that Wheeler was nominated by President Obama?

If this were the Bush White House, there would be endless press stories (and rightfully so) about cronyism and how Bush & Co. were in the pockets of big business. Meanwhile, the Obama DOJ is shortly going to allow a Comcast merger that will lock up the cable industry under a monopoly. The same Comcast that donates overwhelmingly to the Democratic Party, and whose CEO is an Obama golfing buddy.

Wheeler isn't the problem. The Obama White House is, they're directing all of this.

How is it so many people are missing what's obviously occurring here.
eh - and what is that supposed to show? That there's roughly 13.000 projects that vendored a version of activesupport containing a file that allows converting "48600" to a rational value?
Free as in beer. The Unreal engine is proprietary software, and this new UT game will be, too. Epic is using the word "open" and hosting the source code on GitHub, but it's still proprietary (freedom denying) software.
I find this kind of thing disturbing. How often do companies exploit the legislative process like this but with no opposing side to complain? How much lobbying machinery and back room dealing is designed to achieve precisely this at any level of government? Is there even any way to know, much less do something?
From the Python docs (https://docs.python.org/3/tutorial/datastructures.html#tuple...)

And it works fine

I guess Herge mean that? After all, his argument was that a tuple is not always defined by the comma.

There's an interesting paper from a few years back looking at software defect incidence in Windows Vista and trying to figure out what models did best at predicting error-prone modules.

Turns out, in that case, organizational structure had better precision and recall than any of five other models (code churn, cycolmatic complexity, test coverage, etc.)

The distinction is that they won't be monetizing Unreal Tournament 'the game'; there won't be gems to purchase, or hats to buy, or whatever else.

They will be providing a marketplace where other people can sell their own content that they create, which is optional and not (necessarily?) integrated into the main game.

The implication of 'free to play' is that the game itself is full of opportunities to monetize players, or that progression can be sped with currency which you can earn/buy, etc, and that the developer will be splitting their time between bugfixes/features and producing new content to sell to people (at varying levels of balance between the two).

The difference here is that the developers are producing two separate things: one, a 3D tournament-style FPS; and two, a shop where people can sell game content that they've created, and make money from it (or presumably give it away for free).

All of it. However, it is also sometimes done for things you or I agree with.
Sorry, not to imply you weren't aware of the fact but instead to be completely clear. Taken as an cutout of the code I wrote it might seem as though you intentionally removed the forall.

You're right about making sure the problem is gauged to the time available for the interview. I had my senior and lead developers work through the problem individually to see how long it took them. Typically, 10-15 minutes. And they didn't see the problem ahead of time. Wasn't meant to be tricky, but rather do they understand a basic data structure we use all the time in the context of a simple problem.

Personally, I don't buy the complaint that asking a candidate to write some code is unfair although I've had a few tell me so. For onsite interviews, I have them spend a couple of nights ahead of time working on a small web app with a few moving parts (UX, DB, validations) to see how they approach writing larger, more real-world code. They demo the app, then show me the code. Some people take real pains with what they do, fully understand what they used and why, and can talk about how they'd improve it if they had more time. Unfortunately, many don't do that for one reason or another. But this tells me what I/we need to know before thinking about hiring someone as a developer.

When braking you need to optimize the end speed, too fast and your car slides, too slow and you lose time.

(1) Local protectionism

but also

(2) Car dealerships need expensive inventory of illiquid assets and franchise licenses. If the franchise contracts aren't well written (perhaps collusion between manufacturers prevents competition over franchise rights), then a big auto company can maximize profits by selling franchise rights and then a couple years later looking at volumes of sales for which areas it makes sense to set up their own stores and undercut the franchise owners. The franchise owners need to amortize their franchise costs, but not so for the direct sales shops. The argument becomes that the historical implication has been that in the auto industry selling local monopoly franchise rights has implied no direct competition from the manufacturers.

Perhaps a better law would be that no manufacturer with existing franchise owners in the state can have direct sales in the state.

Am I misunderstanding this? reading all the examples, the difference between recursion and corecursion seems to be equivalent to the difference between tail recursion and stack recursion. Is that right?

Thanks! Good work! It's of much more benefit to analyze slow pdfs than to construct the "proofs" that short and simple pdfs are displayed "fast enough" (but I understand that the later feels so good). Especially since it seems that not only pdf.js will benefit from analyzing the slow ones -- if I understand you traced the problems to the cpp code of the browser? That would mean that even non-pdf-js stuff will be faster once it's fixed, is that correct?

They don't chafe because they convey truths about a intangible reality they may not even be able to perceive. They chafe because nothing is actually being conveyed. Its a bunch of words removed from any actual meaning - from the concrete problems that caused the person to arrive to the truth being "conveyed". They're like the conclusion part of an essay with all the rest left out. They tell nothing to people that don't already know, and nothing new to people that do.

Its no wonder people either tend to discard them or to apply them incorrectly.

I don't mean to be abrasive, but landing page could not be less informative. I'm a full-time developer and a big believer in code review, but I have no interest in downloading the app based on the website -- I don't know what it is, really. I think you are going to convert a lot better by actually explaining why I should download the app, rather than just providing a link. Why is this better than current tools? Does this integrate with Github? Bitbucket?
Of course, I am not a fan of violating firmware standards like UEFI/ACPI and dislike it when x86 Chromebooks did this. Having different firmware for different OSes defeats the point of firmware standards. I think it is possible to run UEFI as a payload in coreboot.
Basically any unfold is corecursive.
The series (of continuous functions) converges uniformly, which means that it's Reimann integrable. And you can compute its integral as a sum of the integrals inside the sum (which you showed upthread).

Also, as hinted upthread, just change

f(x) = - sum[n = 0 to infinity](10^n / pi cos((1/20)^n pi x))

to

f(x) = - sum[n = 0 to infinity](10^n / pi (cos((1/20)^n pi x) - 1))

That gives you an actual formula for the antiderivative that converges at every point.

I'm in the UK and I thought the situation here was pretty terrible on the basis that if you go out into the sticks things get pretty slow. There's a joke, that BT develops core telecoms technologies and sells them across the world. Then when they are finally obsolete, it installs them in Britain. However it sounds like the US has cities running on worse than you get over here in farming villages.

When you check-in on arrival, that can cause two problems; one, people (whom you don't want to meet) can come to the location to find/meet/stalk/harass you; and two, people know that you're there and not somewhere else (so they know your car/house/office/dog is potentially unguarded).

You can use checkins (especially those of Instagram or Foursquare addicts) to determine someone's pattern; if they always go to Starbucks in the morning for a snack, then go for a run for 30 minutes, then hit the grocery store on the way back, you can figure you probably have 45 minutes to loot their house, search their stuff, etc. before they get back. If you've seen the inside of their house before, you might know that there are spare keys, or a rarely-used door that you can unlock, etc. which gives you more access to the house later, even if your timeframe is limited.

Etc. etc.

Anyway, checking in as you leave throws off that timetable. People can't come meet you (because you're already gone), and you won't tell people you're out of the house until later, cutting down on their window of opportunity.

The dissertation in question:

http://www.cs.ucla.edu/~sanjamg/Sanjam%20Garg_files/sanjam-t...

Garg's work has been very influential, even comparable to Craig Gentry's fully homomorphic encryption breakthrough. Like FHE, the influence has been mostly theoretical so far, but history has shown that things that appear theoretical today can be practical tomorrow. I'm not holding my breath, though.

While obfuscation has been the most touted application of the multilinear maps, another straightforward application of these maps is for single-round N-party Diffie-Hellman.
Consider a map that respects f(G, G)^ab = f(aG, G)^b = f(G, bG)^a = f(aG, bG). Then 3 parties A, B, C, with secret keys a,b,c can agree on a shared key by broadcasting aG, bG, and cG (let's assume that the discrete logarithm is hard in this group). The shared key will be f(aG, bG)^c = f(aG, cG)^b = f(bG, cG)^a = f(G, G)^abc. This was in fact one of the first applications of bilinear maps via the Weil pairing, discovered by Joux [1].

There's an obvious generalization of the concept to N parties with an (N-1)-linear map, but until recently no cryptographically useful maps had been discovered for this effect.

Actually, charging for concessions (conveniently via the app) might be a very interesting business model. At the very least it might allow them to subsidize their base price, which is super-important given the price war with Uber that's going on right now.

I love Underscore (and Haskell), but I wouldn't consider Underscore an FRP framework at all. It's functional, yes, in the sense that it provides some of the most common FP operations like map, filter, etc, using lambdas. But I don't see the reactive part. Maybe there's some kind of reactive feature tucked away in Underscore's rather large feature set, but I haven't seen it, and it's certainly not core to the library.
That's it! Thank you very much!

> I would think KDE should disable akonadi and stuff by default personally - its super useable without all the heavy weight "crap".

I agree. Unfortunately, they replaced Nepomuk with Baloo in 4.13 (I think; Baloo seems more aggressive than the former) and have effectively taken the stance that users cannot (easily) disable it [1]. It's somewhat infuriating, because adding your home to the ignore list doesn't appear to work as advertised and it'll happily index everything including /var (bug?), NFS mounts, and anything it gets its grubby mitts on. The only solution I found that works is here [2] because there's no longer a UI to disable it (unlike Nepomuk). Beyond that, you're absolutely right: With all the cruft disabled, KDE is quite nice (long time user here as well).

That said, I'm happy with KDE, and I enjoy it in part because of the eye candy (probably a poor excuse). I've used LXDE on an old laptop before but there are always features that I seem to miss. Otherwise, it's great for users looking to avoid the cruft or have limited resources. LXQt brings some of the clean appearance of modern KDE with it, so that's a definite plus. It makes me eager to take it a spin, then possibly try it out on that old laptop--which doesn't play nicely with KDE no matter what's disabled.

But I want to be able to quickly view those massive PDFs, 30MB per page is not particularly large for a large graphics heavy print quality document.

PDF rendering is essentially creating a binary from a source code package. Why would you recompile every single time when the purpose of the format is to deliver an exactly consistent binary output? Arguing that the format is badly designed does not open a document any faster!
I feel uneasy about deploying the wrong version. With capsule, at launch it checks for a new version in the repo (if you configure it to use the newest version rather than a specific one). The packages are only downloaded once: not on every restart.

Alternatively, you can embed the dependencies, in which case it's just like a "normal package", only it doesn't require installation, and is just as easy to create (your build tool can create it). So it's a platform independent "normal package", with added features.
