skysight-inc/HackerNews huggingface dataset:
In this case, there would be one node for each cacheable item. In this case, it's likely one node for each cacheable record in your data store, plus one node for each cacheable collection.

Cycles are reasonably possible, if two cached items depend upon each other. For example, if you store the text of the last comment a user made on HN inside the "user" cache entry, and the user edited their most-recent comment, you would have to invalidate not only the comment but also the user.

Stash treats dependencies as a DAG (directed acyclic graph). During traversal when a node is invalidated, it's aware of the potential of cycles and won't backtrack over paths its already examined.

I switched to DDG after scroogle's shutdown.
DDG feels a bit slower - obvious, since they add some features, while scroogle basically was just a proxy.
What I didn't like about scroogle was their negative attitude (at least it seemed negative to me).

I tried also http://gigablast.com , which is nice, but its index is too small for general purpose searching.
Hacker Monthly Issue #22 - March 2012
That's true of the current ones, but I think the idea is to develop it into a kit with case, manuals, pre-loaded software, etc. to support some sort of programming or robotics curriculum.

Personally, I think it would be neat if the R-Pi could be made into a graphing calculator, which most kids need for their math classes any way (actually they don't need it, but are required to have them). That way, it can be a bog standard calculator by day, and a full Linux workstation by night (after plugging in display/keyboard).
This was actually my original plan, but I took the easy way out for now. :)

We use MongoDB as our data store, and between the UUIDs used as primary document keys and arrays of UUIDs representing links between documents, we could (reasonably) easily determine the dependencies automatically.

As I understand it now, doctors have largely invested in testing companies. When they (not all doctors obviously) - I probably thinking primary doctors - order tests the test is a money maker for the doctor.

Wouldn't a calculation of the effect of litigation include the scenario you mentioned? Otherwise it would seem to be a bad calculation. Do you have any studies that show how often a test is ordered simply to avoid a lawsuit?

one more thing that i assume must work this way, but you don't seem to have documented, is how to test for exceptions. i guess SQL_Exception (a return value, right?) is false when there's no error?

related: do you have any examples that include all the error handling that would be necessary in a real app? how do you display the exception details (it seems to be an opaque type) to the user? perhaps i am missing something here (can't even find exception in the clickable API image)?

(wish i had known about this a few months ago as it would have saved me some work - thanks).
Board of Directors - Biotech vs. Tech
The article you linked to doesn't show this. The pie graph at the end has a big green chunk which refers to, "Remaining health care spending". It doesn't say this only pertains to patient care. Also the chart is about spending higher than expected given our wealth.

I didn't find a place in the article that talked about administrative costs (i.e. salaries, bonuses, profits) that go to insurers.
... and before you knew it, you were recursing and doing all that fancy CS stuff without even trying!
Having lived in Canada for 10 years, and recently moved back to the US because of health care, I can attest that while Canadian health care looks good on paper, it's not. Sure, it's there when you need immediate emergency care. But for anything long term, it's horrendous. Autism, for example, is a perfect example, and something I know first hand. In Quebec? The best thing you can do for autistic children is to leave and get out of there. My wife, a Canadian, was afraid when she first heard about US healthcare, but when she finally got to experience first hand the full brunt of the system, she despised it. We had more help for my son in the first 2 weeks of being in the US then he'd had in more than year fighting for it in Canada.

To top this all off, Canada still has private insurance, and while you don't need it, if you don't have it, it makes for much lower quality of care (and don't think the public option covers essentials, either).

So, no. I could never put my sons through a system like that again. It was down right abuse, and I don't use that word lightly.

How do you explain the low costs and relative success internationally of the NHS (in the UK)?

I've no problem with a free market approach to healthcare when it works.

Fair enough but my point is that these vehicles are not "environmentally invisible". There is still significant environmental impact in the manufacturing, materials, transportation, supporting infrastructure and disposal of the car.
So if they have been lowering prices for 30 years, why do the prices keep going up?

I know there are increased costs due to medical advances, but this only accounts for half the increase in costs according to studies, so the rise from 5% of GDP in the 60's to 16% of GDP today, especially seeing the massive increase in GDP during that period, does not chime at all with the idea that the insurance industry is lowering prices in any meaningful way.

In fact, any rational observer might well assume exactly the opposite.

I don't live in the US, but India does have a health care system fairly similar to the US. The biggest difference is it has less red tape than the US, and insurance companies play a minor role. Most people pay out of pocket and comparison shop.

Costs here did vary significantly for the surgery - the dirty hospital was 0.9-1.5lac (depending on general ward vs private room, etc), the place where I had it done was about 85k. It was the MRI for which the price differential was minor.

I was actually pretty surprised that the price gap was so big - I wouldn't have expected the city hospital to be almost 2x as much as the private hospital.

It seems to me that the insurance companies don't have a great incentive to lower cost of healthcare.

Insurance companies don't have a great incentive to lower the cost of their biggest expense? Um, ok.

On the surface the evidence suggests that they haven't since procedures cost so much more here than elsewhere.

The relevant counterfactual is what procedures would cost absent insurance company negotiation, not what they would cost if US patients had as few MRI's as French patients and US health care workers were paid as little as their French counterparts.
Great stuff! Thank you for the detailed writeup as well!
Really interesting. My first highschool programming class was exactly the same and also during the late 90s. We learned QBasic and created a choose your own adventure game. (My class was actually taught by a math teacher who barely knew QBasic) I also took the advanced classes later which were VB and then C++ and did notice a significant drop off. But, I still enjoyed it.

Did we go to the same high school? :) I wonder how common that class structure was back then.

I think you can fall into a neat little semantic trap where you assert that all languages with novel features are academic, other programming languages are engineering languages and then point out that all progress is made only in academic languages. :)

I was hoping to draw a line between the idea of a language feature designed to solve a real-world problem, and one designed to advance the theoretical state of the art--all of my examples are ones I'd regard as being the former, and I have less interest in looking where they were developed or by whom. Lisp definitely qualifies as the second (and with apologies to Whitehead, all programming language design consists as a series of footnotes to Lisp), as it wasn't even intended to be a programming language, but an AST. I don't think that necessarily means that AOP is an obvious implementation of Lisp macros, especially as it took 40 years for them to appear.

I don't think it's particularly worth running through the minutae of the claims for each point being an academic language or not when it's just a semantic point. I do think it's pretty disingenuous for the article to claim that Python is not an academic language (when it was developed at CWI) but that C is on the opposite side (when it was developed as a skunkworks project at Bell Labs), and that this is one of the many major flaws in perspective and confirmation bias that the article suffers from--unfortunately, much like the claims about programming language theory that it itself points out.

That's not correct. There are private clinics who essentially claim the costs of their services from the government as though they were an insurance company. Costs that can't be recouped in full are passed on to the consumer or insurance providers, or you can be referred to a public hospital where the same service may be provided for free.

As for waiting times, you may find yourself waiting for years but it's highly unlikely. The median time for surgery in Canada is 4 weeks.

Thanks. The documentation for exceptions may be some clicks away, but it's there. Here's a direct link. http://www.tildeslash.com/libzdb/api-docs/Exception_8h.html Exceptions are a "true" exception implementation based on the Except code from David Hanson's excellent CII book. This makes it possible to write more compact code without peppering your C code with return code tests.
Yeah, I understood that. But I tried to point out that it is really unnecessary as the total amount paid is much higher thanks to the fact that taxes are paid in percents. It's a really nice idea for populists but probably wouldn't be good in reality. What have to be done is limit the amount of loopholes where really reach are able to much less then they should.

>The problem is actually pretty simple: hospitals are terrible at cost accounting and totally game it.

It's not that they're terrible at cost accounting. The problem is the hospitals are required to provide care to people who can't pay, particularly in the ER and obstetrics. So costs are shifted from other departments to pay for these services.

That's why people who are trying to hold down costs by zeroing in on this test or that procedure are destined to fail. Somehow the service the hospital is required to provide without reimbursement will have to be paid for, either explicitly or through the sort of sleight-of-hand accounting we see today.

Funny, I had this conversation with one of my professors the other day. I've never written straight SQL--only used ORM. He showed us a giant SQL query and my first question was "do people really write it this way, instead of building up from intermediate results?" It doesn't look maintainable. He said yes, and that the SQL programmers are proud of writing huge queries. The query engine will optimize the hell out of it, so it's the right thing to do.

Absolute Beginner's Guide to Bit Shifting
Perhaps a good way to teach people beginning programming would be to show them how to use a simple web framework.

It would have to be something purpose built to be easy though probably with a dedicated language.

A bit like this:

No libraries or APIs , everything required is built into the standard library.

Database is a simple key/value store that can be used transparently within the language. Something like "Store X = 3" and "Get X" where X is the key name.

Of course you would need some form of lists too, not sure what a friendly syntax for that would be.

Very simple looping syntax, in my experience beginning programmers struggle with this more than anything else.

Something like, "do X 3 times" where of course X would be a a subroutine, this would make functional programming seem quite natural later.

A WYSIWYG HTML editor that can integrate seamlessly with the language itself. Save teaching HTML/CSS until later.

Very friendly error messages that provide links to simple documentation that explains where they have most likely made the mistake.

Documentation should include many videos as well as text.

Graphical debugging should also be taught through a super simple debugger that just dumps the values of every variable at a breakpoint and allows users to browse the DB.

Bayes' rule is quite easy to understand as a Venn diagram, though the linked article doesn't seem to use this fact. But here's a blog-post that does: http://oscarbonilla.com/2009/05/visualizing-bayes-theorem/
In StrikeDisplay, vectors and images are held as Sprite objects in the AS3 sense - which are represented as draw lists internally, and only drawn/redrawn to the canvas as necessary. When a filter requiring convolution or blurring is applied to one of these Sprites, a unique canvas is generated for that individual Sprite+Filter, which is substituted for the original draw list (temporarily). Same thing that happens if you just cache the sprite as a bitmap. So the procedure in StrikeDisplay to draw a black box, add it to the stage and put a blur and a dropshadow on it is:

var s:Sprite = new Sprite();

s.graphics.beginFill("#000000",1);

s.graphics.drawRect(0,0,100,100);

root.stage.addChild(s);

s.filters = [new BlurFilter(4), new DropShadowFilter(2,2,4,"#000000",.8)]

And that's it. It's now automatically drawn to a hidden canvas, which becomes the only item on the Sprite's draw list, retaining the position and transform properties, parent and event hierarchy of the original Sprite. If you modify the Sprite later, re-filtering and re-caching happens automatically. And if you remove the filters, the original vector draw list is restored and the hidden canvas that fed the filtered version is emptied and deleted.
Show HN: NewsFall, Proggit and HN rolled into one time-ordered stream
My comment should have said that absent insurers over that time period, prices would be higher than they are currently. The effect they have is on controlling the level of price increases, not on lowering price absolutely (which I doubt is possible if people wish to keep extending their lives).

I am not saying that insurers are the most effective option or advocating for them; I am only saying that without them, prices would be significantly higher.

If you need evidence, simply compare the total price of any health care service (i.e. total cash outlay by all parties) between a person who carries health insurance and a person who does not. Universally, the price of the service is higher for the uninsured as they lack negotiating power.

It's really hard to say what the performance issue was here, but my experience is that SQL servers do a really good job of handling data sets if you use them correctly. If the problem was a "cache miss" it might mean that one or more tables needs proper indexes for example. Or, if the code involves a cursor and a code loop, that is a very bad sign.
