Compressed representation isn't a trade-off but a win-win very often. When you do in-memory data structures like graphs or automata, you can perform searches times faster if you go for packed representations. What first comes in mind are language-optimised collations http://ow.ly/RVxwa, lossless codes https://en.wikipedia.org/wiki/Entropy_encoding, https://en.wikipedia.org/wiki/Delta_encoding, lightweight LZ https://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Wel.... One still has to decompress data chunks (pages, vertices and alike) to act locally while traversing, though cache lines utilisation is improved by more data loaded to process at once, resulting in better speeds. And you can go even faster if you can traverse compressed representations directly without unpacking, which is sometimes possible. General receipt: always shrink data to go faster, and always verify result in real scenarios.

I don't know that anyone is suggesting that.

I'd also argue a routine diagnostic procedure, like a blood test, is pretty comparable to a mechanic doing an oil change.
It took me 30 seconds of reading Wikipedia and now I am able to do it.

But, are the people in the exam allowed to use the internet?

This is an interesting question (and somewhat meta, given the question itself) about test taking today. What is the point of remembering all that knowledge if you can look it up and understand it quickly?
But people who trade against fundamentals aren't trading directly against future profits, they are just betting on long term price movements. HFT traders are betting on (very) short term price movements.

According to the theory that stock prices are a martingale (which is well established), there is no qualitative difference between long and short run price movements. In particular, there is no reversion to the mean in stock prices [0].

[0] Of course, there are going to be literally hundreds of papers exhibiting some reversion to the mean effect. But this effect is always tiny.

I'd do it if I have cause to fly into the States again, but I can't help but think its not really going to help much. From my youthful experiences at being a knob, I'd say don't piss off food makers/deliverers, or airline staff. I once annoyed a Qantas security lady, and I noticed it for a fair few trips afterwards. Then again, with wealthy interests controlling the US, I can't really see what will help at this stage. Its a descent into corruption and mess, but I can't judge how quickly it'll crumble.

The article is talking about toner; is that really also true for laser printers?
There's a balance to be struck, for sure, but cost transparency as an alternative to complete and total cost opacity is a move in the right direction.

My daughter fell at lacrosse practice and hurt her wrist. We had an x-ray, which proved inconclusive with the swelling, another x-ray after the swelling subsided, which also resulted in an inconclusive result, followed by an MRI which indicated a bad sprain, for which we ended up getting a very cast-like splint.

This is basically the same as what we thought from the initial x-ray, as even then the doctor was advocating for a splint in the absence of an obvious break.

If costs were more apparent, we probably would have had an x-ray once, and then gone with the splint, but price opacity and insurance obfuscated the costs enough that we naively opted for the more diagnostic approach, which proved to cost a lot more than just having gone with the splint initially. As a developer, I'm inclined towards the "know what you're fixing before building patches" approach, so the diagnostic approach was logical to me, but had I known that the end result was basically the same either way, I could have saved myself the cost of an x-ray and MRI and just skipped to debugging.

Hmm, I use your TLS cert but I didn't see the CA-signed one I can use. I'll read the blog post below, thanks.

Ahh, I'm an idiot. Thank you for pointing that out to me. xip.io uses dots and so my brain just assumed dots on this one was well. I still would be very interested in finding a provider that did this or gave a reasonable number of domains on the cert. Though wildcard on subs is what I really want without having to buy one for each sub so I can do:

.server1.joshstrange.com

.server2.joshstrange.com

etc...
Hah. So sslip.io should went with Startcom instead of Comodo.
I read this book in college (1970s), but the bit that sticks in my memory was his discussion of observations through Galileo's telescope. His observation, and others' confirmation, of Jupiter's moons, the phases of the planets, and other phenomena helped end the Ptolemaic era, and had a profound effect on the development of science. Feyerabend starts with the idea that "anything goes" and tries to support it by describing some anecdotes of people who looked through Galileo's telescope and said they couldn't see anything. He thinks these anecdotes should be weighted equally with the body of detailed astronomical observation, and thinks it was arbitrary to base scientific models on observations of what, after all, were real things. He starts with his conclusion and finds anecdotes to support it. I suspected at the time that he wasn't even taking himself seriously, but plenty of other people seem to have been.
I'd say they've been consistently mediocre for the last while
I really like the idea of this. It's a shame that it doesn't seem to work at the minute -- I'm guessing we gave it the HN hug of death.

What data sources does it use?
You are missing the point of my objection.

For starters, I said modern. Most of the big recent breakthroughs in AI have come from neural nets. There is a inherent problem with deep learning with neural nets. Neural nets are exceptional at finding patterns within a huge dataset, but they are REALLY, REALLY bad at predicting new patterns that they haven't seen. Even something as simple as the pattern a^2b is impossible for a neural network to generalize past whatever length of the pattern the neural network has seen without modifications (check out stack-rnn by facebook).

Even if an AI is trained for years, I don't see this limitation being overcome by pure magnitude of data with our current techniques. You say I don't have enough "future vision", but all you are doing is basically guessing that AI researchers will make some huge breakthrough that significantly changes the direction of the entire field. You are playing the lottery with your guesses, I'm simply extrapolating current trends.
"Servicise" everything. The purchase of the UBER-toaster has a web-service associated with it. Do you really want the toaster or do you want your bread toaseted? When you re "sell" the toaster the service goes with it, it cost money to provide this service, so maybe the service provider is due a portion of the resale?

What exactly do you do when you need math skills in developing? What do you develop with it? Some specific examples?

I've done math while developing 3D stuff, physics simulation and a lot of things - yet I never felt like my math skill mattered that much. And I really dislike theoretical math like in school.
Hmm. I hadn't thought about 'no learning on the job' as 'this will stall my career development'.

You make a really good point. There is a certain area between 'you don't have the skills needed to become useful' and 'you can pick these up in short time' - but I think I have been looking at this wrong another way. I do apply to positions I feel I'm unqualified for (within reason), but it's also ridiculous for me to think companies expect all-knowing engineers. Any other trade would have a worker learning new skills on the job.

My resume does change fairly often - I had an interview a couple weeks ago where I was a little embarrassed because I went in with my current version and they pulled out the resume I had from 5 months ago. I was like, 'er... may I see that?'

On a side-note I think wining and dining potential employers is a fabulous idea, even friends for interview practice.

Thank you for your feedback <3
That would be Sun, right? Particularly Scott McNealy: https://www.google.com/search?q=scott+mcnealy+microsoft (not needed SGI's special sauces, almost all my direct experience here is with Sun and DEC).

In addition, the two biggest and interlocked problems with them that I know of are their ruining their reputation in enterprise space when they messed up an off-CPU chip cache design, required customers to sign NDAs before they would try to fix it, and then blamed the customers and the supplier of the SRAM chips for their non-fault tolerant design. Instead of, you know, the IBM ethos of fixing the customer's problem.

Related, in terms of zapping the other channels of sales that might have saved them, was a total internal sales focus on enterprise sales. If you weren't making enterprise sized purchases, several million dollars worth, you were sent to a 3rd party like a VAR, but they typically wouldn't give you the time of day, they certainly were difficult to deal with when I worked with companies that bought one or two Sun workstations. Adding a web site that allowed direct purchases mostly added salt to the wound.

What this meant was that startups that needed more Sun kit than they could charge to a credit card on that web site were forced to go with Dell, who's machines weren't as good, but had the strange property of being willing and able to sell them (HP's sales operation was too screwed up at the time to be a big player here). So a bunch of companies learned how to make do with Dell servers, and the successful ones never looked at Sun when they got big enough. So they missed out on the big post dot.com sales.

A final straw when they started struggling was reducing the quality of their systems, e.g. saving one chip on a motherboard by using a chipset Marvel controller instead of the well tested and trusted Intel one. And I read that Joylent stopped buying Sun hardware when they started silently changing the lights out hardware they were shipping in their systems (IPMI or the like).
I do the same. Keep up the good fight!

Point taken. Isn't that just a limitation of current tools, though? What stops ZFC from proving sentences about Python interpreters, or Brainfuck programs, or whatever? I'm not aware of any theoretical roadblocks, apart from the difficulty of actually writing out the proof (which is admittedly huge).

Sure you can. I know a few people who lost their luggage - in those situation they just claimed the maximum value the airline would pay, so they suddenly had 5 laptops and jewelry in their luggage.

I think we're confusing "lifetime" in the reliability sense with "lifetime" meaning how long this particular LCD part will be available from the supplier.

I've been working with these types of LCDs for a long time, and when it comes to these WVGA/SVGA 7" units you can get a ton from Asia at great prices but the factory will literally disappear in a few months. The LCD fabs constantly get bought/sold/churned as the major players like Sharp and LG shed off their last-generation fabs and the other smaller fish scoop them up.

Ideally a group like RPi will want to have the same part available for a long time so that they don't need to create new revisions of the interface cables, power supplies, or software drivers to handle the change. It's nearly impossible to autodetect one 7" LCD from another via software so you need to configure it entirely in a bootloader or kernel configuration line. And then that becomes a massive support issue.

Why it's hard to write about code
It depends how you define CS; some people I work with don't consider CS and Maths to be different subjects ;)

Personally, I find the topological perspective useful for thinking about types. I would guess most programmers think of types as sets, which is perfectly fine for the kind of first-order tasks we encounter in almost all day-to-day programming. However, it doesn't give much intuition when dealing with the crazy kinds of abstractions we find in languages like Coq, Agda, or even some of the funky new Haskell extensions. Whilst the vast majority of programmers will never, and should never need to, deal with that level of abstraction, it's personally the kind of programming I really enjoy :) (My own work is in the area of formal proofs, proof search, program equivalence, etc.)

I think HoTT's key insight has already been made: although using UIP (or one of its many equivalents) to ignore the differences between proofs makes life easier in the short-term (eg. as a Coq user I was blown away by Agda's ability to do pretty much everything by pattern-matching on refl), in the longer term all of those transport lemmas, path inductive proofs, etc. give us tangible benefits; firstly for explaining why something is true, secondly for allowing new kinds of higher-level reasoning and thirdly for aiding mechanisation and computation. Essentially, HoTT is just a logical extension of the intuitionism/constructivism ideals :)

Hopefully HoTT, or something very much like it, will narrow the gap between what people know and what machines know.
I really like it! easy to integrate and great feedback is one shake away.
Won't their definition conflict with the rectilinear definition? Specifically, there are distinct rectilinear configurations which are homotopic. With two bricks connected by at corner, there are two rectilinear configurations but both are homotopic. So their method used to count "homotopy equivalence classes which contain at least one rectilinear configuration" would yield a lower number than the previous result. This seems to contradict when the paper says that their definition extends the previous one.
I've been through the training for airport security officers (not in the US, though) and that's one of the techniques they taught us. Also most baggage locks are ridiculously easy to pick with basic tools (literally a 15-30 minute lesson) even if you don't have the master keys available.

This. One thing that kills escrow systems dead is the complacent spread of authority.

You start with critical keys that are closely held. Over time other parties express the need for access ("Okay, if you promise to be good"). Nothing bad happens (that anyone can prove...) so over time more entities are brought into the circle of trust. Eventually the dog-catcher has access to your stuff.

There's no way these keys haven't already broadly leaked (I mean, before these pictures).
Can you give an example of a company that failed because somebody chose Python? Or even one with materially worse business results, say a 20% reduction in revenue?

My guess is no, because people make fine businesses out of nominally unscalable technologies all the time. Rails is a notorious performance pig, for example, but there are plenty of successful businesses built in it. When server bottlenecks become an issue, modest performance tricks and ops magic are applied, and suddenly per-server performance is no longer the problem. And still, despite being a pig, Rails is a great place to start, because its real power is not CPU efficiency, but ease with which you can get something workable up and then iterate.

There is no language that is so fast that it's infinitely scalable out of the box. Every software company that grows hits performance problems with naive uses of the tools at hand. Every successful one figures out how to make things work. And making technologies serve the human purpose at hand isn't a characteristic of good languages; it's a characteristic of good teams.

Hey community, what do you think about our startup? Any ideas are appreciated
Source needed.
Agreed, it's mostly fit and finish. Truth, if we only look at on road performance the CTS/ATS probably beat the 3 series. But the interior of a BMW is just leaps and bounds above the cheap feel of the Cadillac.

Source, daily driver is a 2013 3 Series and my brother is one of the engineers doing NVH testing on the CTS/ATS, we compare notes frequently. And, as part of his job he did have to test the other vehicles in the class.

Honestly, after a relocation I can't really justify the cost of the BMW so when my lease is up I'm going to be REALLY sad to get rid of it, nothing else seems to really come close.
Hey, thanks for acknowledging the idea. May I point you to the conditionals in my post implying the possibility of a honest debate? Instead of aggressively caricaturing and strawman-ing me, could you try to discuss it?

- Where do you see the slightest tentative to put "myself in a good position" ? I'm making a proposal and seeing what other members of this community think about it.

- Bravo for implying I'm saying "fuck to content creators" . Because, yes, I have both Patreon and Flattr accounts donating to a few of them. But like said elsewhere in this thread by another commenter, this fails to compensate "one-off websites" and am discussing what a solution could look like without the drawbacks of advertising.

- So because of some technicality (ISPs not agreeing) we are prohibited from even talking about changing anything?! Applause, nice approach to problem solving.

So, they spend all that time cramming for the exam, and presumably pass it and enter the civil service. Is there any requirement for follow-on and continuing education? Because I can see that if someone does all that learning, but then just stops, that could be a problem.
Is calculating statistical aggregates over a long period of time ridiculous? Many service based procedures have uncertain length, flipping a coin to arrive at a price doesn't seem like a great solution either.
Depends on the procedure doesn't it? You might not price open-heart surgery that way since you want a great doctor, price be damned.

But what if it's not so serious, and not an emergency? People have rotator cuff issues that they take years to get fixed regularly. Or a hip replacement? That's rarely an emergency but rather a solution to long term pain that's not painkillers.

I think the other thing a lot of people would like to see is some kind of doctor and hospital report card so that you could compare on price AND quality. Which would be great as it'd force the terrible surgeons who regularly do such a bad job (accidentally or on purpose) that their patients have complications, die, etc out of that line of work.

Obviously there would have to be some kind of risk classification system so that doctors and hospitals that take on high risk patients wouldn't be punished for doing so, but I think that some kind of "hot or not" style risk assessment system could be developed whereby doctors spend 15 minutes a day reviewing risks anonymously for other doctors and each case gets rated 5 times and that determines the risk score to hopefully remove all bias.
I use it exactly for that, and it really helps me when navigating in Emacs (holding Ctrl with pedal is much easier than holding it with your pinky). Your experience may vary, of course.
