Here's his update:

While all those suggestions are equally valuable, I've personally chosen to say to my customer that I accept to do the videos, but in this case, we must renegotiate the contract, keeping in mind that there will be a considerable cost, including the additional fee for copyright release. The new overall cost would be in average three times the actual cost of the project. Knowing this customer, I'm completely sure that he would never accept to pay so much, so the problem is solved.

Second update:

The customer effectively declined the proposal to renegotiate the original contract, taking in account the considerable additional cost.
Depressing. Because no matter how I manage and what I'll actually achieve, it'll be too short anyway and I know it. Being reminded it is too depressing.

"So, why do pans get so much more expensive as they cross the ocean?"

My guess? Because pans get sold by experienced companies who recognize that the price of an item is decided by its utility and the amount people are prepared to pay for that utility, not anything to do with the cost of manufacture. The gap between the manufacturing cost and the utility value of an item only lets you choose whether or not to be in the business of selling that item.

Well there's the problem. It isn't that php isn't the newest technology -- but rather, that php is a horror to work with.

I'd jump at the chance to work with Lisp (which is far older than php) because it's a joy to work with.

I'd dearly love to work part-time so I could devote more time to writing and personal projects. And I'd love to be able to telecommute so I could do some traveling while working. And for those opportunities I'd happily work in Pascal, BASIC or even COBOL.

But I just can't bring myself to touch php again.

To play the devils advocate here, What if the customer wants to have a blog series on how that product was built? Key software design decisions, features, etc. What if he wanted to run this video by another software developer who only agreed to do software reviews, etc. How different would this from recording a bunch of screencasts on building a product. The customer gets knowledge of the entire build process, from the initial sketches to the final release.

But most if not all of it would be too much to deal with for a freelancer and should at least incur a 3x price increase to deal with the various variables involved.
I'm far from claiming that the proof is invalid based on my feelings on the subject.

My only issue is that in the article, and in other writing on the subject, nobody is even contemplating the possibility that Mochizuki's work might be unreadable for reasons other than it being too brilliant to grasp.

I wanted to present an alternative possibility which seems to be disregarded at the moment in favor of the attractive "eccentric genius" narrative.

Politically I agree, but Objective-C is a better language than C++ or Java, and Cocoa is a better framework than the STL or the Java core libraries. That's before we get to the GUI experience. Learning it will make you a better programmer.

It seems that he ended up doing the work as per the original contract after telling the client the video recordings would mean paying 3x of the original amount.
The person who asked the question on math.stackexchange.com referred to news reports, and is asking what is essentially a historical question, so the question really should have been asked on a question-and-answer site about historical research rather than on a site about mathematics. That's why the answers are so irrelevant to the nature of the question.

The Nexis commercial database of news stories may be comprehensive enough these days to answer a question like that in detail going back to your own birth year. It would cost money to do the Nexis search, and you'd probably have to pay someone to pore through the search results and edit a document that would accurately summarize the results, but this should be a solvable problem these days.

(As another comment here has already pointed out, the basic answer is "Every time someone becomes the oldest person in the world, that person eventually dies," but I take it that the question actually asked means "How often does the identity of the 'oldest person in the world' change to being a new individual?")
I couldn't find an industry average but my credit card gives 1.8% above IBLR (interbank lending rate), normal currency conversions for transfers from my bank account are even lower. But that is beside the point since I don't WANT to convert it (and neither does OP) there are lots of things you can buy with dollars.

Since they do allow you to transfer USDs if you happen to have a USD bank account with a US bank it is very unlikely that regulation says they cannot do that for non-US banks (they are registered as a bank in Europe). As a foreign national you can only have an account with a US bank if you opened it before 9/11, so most people are stuck. IMHO they are simply taking a few extra percent because they can.
> With any system implementing ACK packets (tcp is one example) a link that fails but is then fixed is the same as a very slow link.

This is only even theoretically true if a) you have no bound on memory and b) the link will always come back up. In practice, neither of these is true.

Further, if you're relying on never being partitioned then any network break requires delaying availability until the partition is resolved. CAP is then relevant if you're not willing to do this (and virtually no one is going to be so inclined).
It seems there are a lot of gaps in his primers -- he includes topology and some intro to Python, but the actual heart of programming -- algorithms and algorithm techniques -- is mostly missing.

This is of course his right -- it's just a collection of blog posts after all -- but caveat lector.

I would probably go for textbooks instead. Textbooks usually do give a bigger picture in the topics mentioned and they usually have an acceptable learning curve, so no additional primer is required (though as always, googling additional info is a plus).

If you're learning CS, it's often super useful to mix and match two or three textbooks to get a nice picture of things. For example, when you're reading an Algorithms book about graph traversal, it's nice to read a book on graph theory as well. Conversely, several equalities in graph theory can be proven by a simple algorithm (greedy or DFS, for instance).

My personal favourite is mixing up Dynamic Programming (from an Algorithms textbook) with recurrence solving in a discrete math book (which is what DP is actually about) and mixing all that with a more advanced chapter of discrete math -- generating functions.
How To SEO Your Video Channel for Long-term Success

I bought USD$2 with some of my ripples. I was indeed looking at it backwards. Lower prices are better, if you have a lot of ripples, because it's the price of USD/XRP. (Not the price of XRP/USD).

But now I have $2USD in my Ripple account, and it's just like the imaginary numbers in my bank ledger, without any insurance or other representation. And no obvious way to get it out. [Edit: I figured it out.]

This is very cool. My only comment, i would consider changing or adding to your description, "Present any website without additional software!" something like, "remote website presentations - nothing to install". It took me a bit to grasp why this tool would be useful. It's for doing remote website-only presentations.

I can see this working well with online presentation services such as http://www.rvl.io/, https://presentate.com/, https://speakerdeck.com/, https://www.lucidchart.com/, http://www.slid.us/ etc. Or build-your-own tools like http://jmpressjs.github.io/customize/, http://flowtime-js.marcolago.com/, http://imakewebthings.com/deck.js/, etc.
Hey, could you wait about 6 months and follow up my thread?

I have about 2000XRP and I believe you that the value will go up, but I just traded some for $2USD and I don't see any way to get it out. I don't want to ask anyone to get out of bed for 2000XRP. But maybe in 6 months.

Your post sparked a thought. We've been hearing about 'cure' for depression. From the point of depression, isn't the baseline a 'high'? Yet, we're told right from childhood that drugs that put you on a high are not acceptable. Is our brain not on a high naturally then, and could you classify depression as the wearing out of the hormonal high? Just as one is able to make better judgement at the base line if compared to being high, (as you say ->) people are able to make better judgement at 'depressed' than normal. I don't even know what I'm talking anymore, but I think we should stop seeing the depression as a problem and start accepting it as a state of not high/not baseline, just as the baseline is accepted as a state of not high.

" you need to abstract away from standard preschool algebra and build up models that then let you get said general results"

Yes, of course.

" but could you maybe still make a suggestion on how to better think about problems?"

And that's what I meant. Thinking about problems in a different way (but still provable, and still working in a similar way)

For example, for Peano arithmetic you have that equality is symmetric (and transitive)

Now, there are several ways to explain that, and it's usually explained more or less by "for all X and all Y, if X = Y then Y = X"

Now, it would maybe be interesting to have a 'different explanation' that is as powerful as first order logic but works differently (and maybe easier to compute)

For example, it may be possible to write Peano arithmetic as a grammar (so zero would be ' ', one would be I, two would be II, etc)

Only parents can judge when children are mature enough to wield guns, and obviously some will get it wrong. My father started directly teaching me how to shoot when I was around 6. At 3, he would start taking me and later my siblings with him when he went hunting, so he started teaching by example at that age.

His guns were never locked up, our parents "gun proofed" us, taught us about danger and responsibility. They're from the Silent Generation, it was assumed back then. Heck, my father and many of his classmates would store their hunting guns in their school lockers so they wouldn't have to go back home before hunting after school.
The ATMs can be configured for both cases. If the ATM is in a well-trafficked area, with a (normally!) low degree of crime, the bank may set it for high-availability vs. hard-transactional to avoid inconveniencing their customers.

Don't forget that the banks make their money from ATMs off the transaction fees, so if a foreign customer's bank is unreachable at that moment, they may still take a chance and give them their money (plus charge them the $4).

I think there are a lot of gaps within the primers too. With a degree in Mathematics and CS, I can only follow through midway most primers before requiring to find additional sources of information.

It's not just the cost of the new cards -- all the payment terminals would have to be upgraded as well. AFAIK, unless you're in a major international city (NYC, Washington DC, SF) the terminals in the stores & restaurants don't know what to do with a chip-only card.
It's presumed (and pretty much a given) that it's being worked on. However there has never been a full confirmation from Valve/Gabe Newell on anything specific.
It's likely a combination of both. A quick way to discern would be to look at velocity, zdr, and rhohv. For ground clutter and returns caused by the inversion, you will expect to see very low velocities(close to 0) relative to the background precipitation. Additionally Zdr will end up looking like a roughly random field. If it is insects, then the velocity will roughly match the background precipitation, but you will have a high zdr(as insects look like very very oblate bags of water). In both cases you should get a drop in rho_hv, the correlation coefficient between the channels which will help to differentiate it from actual precipitation.
Also it looks like you're primarily concerned with pulling out the rainfall in several cases. For this, I'd look at the specific differential phase(K_DP) as it is a much better estimator of rainfall than reflectivity. In general, it is linearly proportional(exponential, with an exponent close to 1) to the rainfall rate. I'm not sure how good the nexrad estimators are for kdp though.
I agree it would be nice if the gaps in his primers were filled in, but it's to have a resource like this that can help give an understanding of at least some of the topics related to math and programming.

I know from my experiences that trying to read a discrete math or algorithms and data structures textbook can be very daunting. I've also tried viewing the lectures of the algorithms class on Coursera and usually give up because of the difficulty of trying to learn these things after spending 8 hours coding at work. Not having a background in computer science makes this into an uphill battle. Any resource to make this struggle easier is greatly encouraging to me.

That was fast!

I can't access it on my mobile at the moment as I'm at work and for some reason right in a 3G blind spot, but on my PC it's looking very nice.

Honestly not sure what you could change/add now as it's pretty much perfect for what it's aiming to be! Only possible thing is aligning the 'I want to go to bed at this time' textbox time format with the other times displayed, i.e. the textbox uses 'HH:mm:ss' while everything else uses 'hh:mm am/pm'.

EDIT: just checked it on my iPhone. Looks and works great. 'I want to go to bed now' drop down functions really well.

The customer clearly doesn't understand how creative work is done and approaches it with a factory mindset where workers are busy with their hands. A large amount of software development work are done in thinking, which appears to be inactivity to the outsiders. A lot of problems are solved while taking showers or driving. Does he want to video record those?

Two approaches for this client:

- Simple say no, and don't waste time trying to reason it with him.

- Just say no to the project and move on.

Almost. Federal law has age limits, 18 except for 21 for handgun ammo. Mail order is entirely unregulated except of course requiring an ORD-M sticker and ground shipment.

Some states have regulations, from one outfit I buy from they would be California, Delaware, D.C., Illinois, Massachusetts, New York and Ohio, they warn you to check your state's laws before buying. Which leaves out a few of the worst states like New Jersey and includes one mostly OK state, Ohio (worst thing about it, unique in the nation, is that in a self-defense case the burden of proof is on you, but it otherwise has shall issue CCW et. al.).

You don't sell time, you sell a product, even if it's part of a 'project'.
The points in the article are important to consider (sampling bias etc etc) but they apply to ALL attempts to analyze data for patterns.

For me the utility of big data is simple - more samples. Even if the effect is small you can find it and have more faith (word used on purposed :}) it is not noise that has escaped your significance test.

The dataset may be biased. That part requires wisdom to know and honesty to say what the limitations of the analysis are, but it is by no means restricted to "big data".

But the article as a rant against buzzwords is something I can get behind.

I think it really is what your parent said, for any other large existing automotive company, each car is a small piece to their overall offerings. With Tesla, they have a single car that they push extremely hard to perfect, because they need to make this kind of impact to get some remote chance of a stake in the automobile industry.

Basically, rev 2.0 desperately needs to be this good, otherwise no one would pay attention.
That's more due to less fire hazards than in the past (minus the illegal apartments, which now increase them). Better building materials. Old apartments and houses used to be real fire traps. Also, I think smoke detectors have a lot to do with it. But it's not helping that firehouses continue to be shut down due to budget cuts. Some day we will be paying for that in lives lost.
As the article indicates, Wal-Mart's limits are only due to the severe, we've never seen anything like it before, post-Newton ammo shortage. My other comment in this subthread addresses the existing limits as I know them.
