I see both arguments.

XML became popular because of its human readability compared to binary and allowed disparate systems to cooperate. JSON is even more readable and allowed the whole XLST thing to be ignored, making a dev's life easier, and really took off with node.

Binary is not gone, but you don't see a lot of it in the 'web world', because everyone in that space is JSON, almost exclusively.

Having written many parsers, binary is by far and away the easiest: provided your language/environment supports it. That is, binary in js is a pain, because you don't have native ints and floats. In js, JSON is the base atomic data structure, so it makes complete sense that it's used... But in c/c++ and co. JSON is harder and introduces a lot of overhead/ quirks which simply don't exist in binary (provided you cover the buffer overruns and co.)

So if you create a new business you must pay a Google tax to be indexed. What about Bing?

If you have an obscure blog about gardening or ponies or microprocessors you must pay some fee to Google to get indexed. Is it a one time fee or it's yearly?

I guess you can have a page in Facebook and they will make some arrangement with Google. The big wallet garden host can make some similar deal (probably in exchange of placing ads in your page).

What about personal pages of the professors in the universities? There is a lot of good material there, some courses have almost all the material online.
In no small part this is because parsing long opts can be significantly more complicated than short ones. It is by contrast very easy to parse short, single-letter flags. Not saying it's not worth doing, but there is a reason this has not been standardized.
that's too bad... they should index all of it

São Paulo is an oppressively ugly concrete jungle. Most of the buildings are the colour of what babies would shit if they ate cement all day.

But anyone who has read a book about designing a home solar system can tell you that all of the literature tells you that you have to pick the location of your panels carefully so they aren't occluded by trees over part of the year because the power losses due to occlusion are significant and can make a system non-viable and non-economic. From the book I read [0] (although mine is the 2015 edition), not planning for obstacles is the #1 reason solar power system designs fail.

I'm not sure why they didn't hire an experienced engineer for this multi-million Euro project.

Busybox has good reason not to change. It's focused on being lightweight and embeddable, not being user-friendly. It would have to catch both types of flags to maintain compatibility, and parsing for long flags is definitely more complex. Coreutils are different, but busybox is fine with short flags.

By the way, oil does look interesting. One key issue is you really need to move to python 3 asap. 4 months and change before it's no longer supported. Plus, people want fancy unicode stuff in shells these days, and that's much easier in python3. Out of curiosity, do you think python vs c will have a major impact on performance? On the other hand, I figure stricter semantics means more room for optimization and slow-down on corner cases. Are there any performance numbers I can look at?
Yes - it’s valuable language that will really be valuable in helping you reason with code in the future... it’s a real shame colleges started using java instead of c and c++ as a starting language. It’s helpful to understand the building blocks that get us to languages like java or interpreted languages like python and ruby...

If my experience of Virgin Media is anything to go by, they are probably writing them down in crayon on bits of paper that they keep in a very large box, probably outside and open to the weather.

Actually, it wouldn't surprise me if they just didn't store them at all and just accepted any login attempt.

Given the level of incompetence I have experienced from them, I can only assume they are still in business because of a serious accounting error in their favour.

I found my local cabinet with the doors swinging open and a massive tangled bundle of wires inside. I reported it to them, but they haven't done anything about it for more than a year, other than remove the notice asking you to report it to them if you see it open.

Frankly, I suspect I could build a more reliable link from a bit of string and a couple of plastic cups.

Worst ISP ever.
> History is full of airplanes that were built or modified (sometimes improved) by hackers.

The FAA won't let you fly it until an engineer goes over your design. For very good reason.

An unbalanced airplane isn't going to fly, and one that isn't strong enough will fold up on you. There's a thin line between strong enough to hold together and light enough to get off the ground - and you cannot find that without math.

There were many hacker airplanes before the Wrights. They were all too heavy, too underpowered, too unstable, and too weak to fly. The Wrights, with math, solved those problems.
Ok thanks, so now I'm trying to understand why the people behind Wattway couldn't make this simple estimate.
I find "virtue signaling" is a useful concept; It's the idea of doing public things that signal how virtuous you are, but don't have the impact they suggest. Example might be front-yard cactus gardens to save water compared to lawns ? (while ignoring washing , agriculture, and industry )

I had a brokerage account that I closed out by transferring all of my stock and cash to another brokerage. Apparently they failed to transfer it all and left 2¢ in the account. For nearly 10 years I’ve been receiving mailed statements from the old brokerage with my account details. I wonder how many other accounts are in this limbo, and how much postage (now over 50¢!) is being wasted on these mailed statements.

I’m glad my only inconvenience is having to recycle the monthly mailings, and not mounting fees, like the people at Wells Fargo!
Still, it might be a simple division of labor thing: one group specializes in believing, hard, and pulling in the money, another group says "well, they've got the money, let's try to build the least bad version of this travesty, if we don't take it someone else will"
Asn.1 is incredibly hard to actually implement . There are dozens of cases of security bugs based on bad parsers. Also there are a dozen different encodings of asn.1 data including json (JER). Its age also means that it has a bunch of obsolete datatypes.

I love the whole “bicycle of the mind metaphor”, but think about what it means in the context of omnipresent smartphones: using a bike burns a lot less calories than walking , so what does it do to our minds if for so many mental-related things, instead of applying our mind to them the hard way, we use our pocket computers?

What would it do to my body and my weight if for every meter I used to walk, I would instead take the bike?

You have a set of stocks either correlated with the U.S. economy or China's economy.

Amateurs tend to pick uptrending correlated stocks (all stocks trending up in the U.S.). When U.S. economy crashes, all their eggs are in the same basket.

If you'd tell the amateurs to pick the inverse, they'd go for downtrending Chinese stocks. When China's economy crashes, all their eggs are still in the same basket.

I think what you are looking for instead, is contrarian trading strategies. Here you follow counterstrategies to what the large herd is doing. A good contrarian strategy for buying bitcoin, may be to gauge crypto sentiment on HackerNews. If the majority is gleeful or pessimistic, the price is too low for future value, if articles get posted on how to build your own blockchain in Python, then you should be ready to start converting to money, because one month later, every smart nephew's uncle fomo-bought and panic-sold the hype and caused a crash or depression. Similarly, if the U.S. president is glowing about the heated economy, and dismissive of China, this opens up new profitable options for contrarian traders (which are less risky/more informed than completely random or following the herd).

Thank you for your reply! The help you describe is definitely an idea I can get behind. Just one question: What do you mean by ECR?
As a Brooks reader, I've idly daydreamed about repackaging it as buzzwordy management advice and making a fortune. The issue is that there may not be a market for good management advice, whether down-to-earth or buzzwordy.

I tried to suggest a surgical team at one job, but it didn't really compute for anyone else besides me. (I would not have been the surgeon.)

If you're reading this comment and haven't read Brooks, consider it - not too much of a time investment for the perspective.
Many languages have libraries built in that do something reasonable with JSON. Usually you just make a class or struct, instantiate it, and then generate JSON, no need to have a separate compile step. When going the other direction, I usually just format the JSON, copy that into my code, then fix the compile errors.

XML has all that tooling because it needs it. JSON is a lot more straightforward, is more compact, and is faster to parse and (probably) generate.

If you're going to go through the effort of a compile step, you should probably just use a binary protocol, which will get you even better performance and getting documentation out of the box (e.g. protocol buffers schemas are very readable).

I see absolutely no reason to use XML these days as a data format, but it's still a response choice as a markup format (you know, what the M stands for).
In my experience it doesn't make much difference whether you pay the bills or not.

They sent me to a debt collector more than a year after I had closed my account, for something I didn't owe them (it was a bill for services after I had closed my account and been physically disconnected). When I tried to talk to them about it, one of their call centre managers eventually admitted to me that there was no public number that could get me through to a call centre that had anyone able to sort it, or anyone they could transfer me to who could sort it, so I might as well stop trying and sue them.

I got it sorted by tracking down one of the company executives home contact information and calling him about it. I harrassed him considerably less than the debt collectors harrassed me.

Yes, but a lot of people who are aware of their lack of understanding (or reduced understanding) actually choose to stay silent, or offer opinions with a lot of riders.

> Every documentation I've seen is quite light on the branch prediction improvements.

In one of the pictures in the article, it says the new architecture uses the TAGE Branche predictor. This is likely based on the work of Andre Seznec. There are many articles on the implementation (but they can be difficult to understand if you are not already familiar with his work).

I've implemented the bare bone predictor on a computer architecture course, you can see an abridged version of my presentation slides here[1]. Note this only describes the bare bone predictor, in recent work Andre Senzec added a Loop predictor and a Statistical Correlation Unit to increase the accuracy.

There are some work using TAGE with perceptions in the Statistical Correlation unit.

It's more than that. We simply don't live in a world where physics is in favor for doing this.

Many people have done more than back of the envelope calculations to show this simply was a non starter.

Those (people who took money to build ) push this idea are either ignorant at best and dishonest at worst.
Paulistano here too, and nikkei (so pretty much every weekend went to liberdade and sao joaquim).

I find it easier to walk around Sao Paulo now. And Liberdade is still a special place with the asian lanterns in the lamp posts, the Bradesco building, and there are stores with Noren and signs.

Only difference is that the signs are now proportional to the store facade.

And we still have grafitti that helps to keep the city interesting, as well as our Portuguese stone pavement and other little things that make Sao Paulo beautiful even without all the billboards and ads.
Agreed. However, the company had the right to give or not. To assume you personally are owed something because someone else has it is a fairly new and large cultural issue within tech. You don’t see this coming out of any other sector. It’s like my children saying that they are owed my money in their inheritance. It’s my money, I can choose what to do with it. Within bounds, anyone has the right to disagree with their employer, change jobs, or start their own company. But never feel that you are owed something.
You have to distinguish between inflation (which every country has, on varying levels) and hyperinflation. Zimbabwe's inflation hit 89.7E63% per year. No, that is not a typo, it is actual powers of 10. In contrast, in Syria inflation is on the order of 20%/year, driven by real-world difficulties in importing and producing goods rather than a drastic expansion of the money supply. That is, when inflation is directly caused by disruptions to the economy, it's on the same order of magnitude as those disruptions.

In the German case, there was no massive damage to the economy; the war had been fought on the territories of France and Russia, and the only major disruption was a brief occupation of and general strike in the Rhineland, affecting maybe 10-20% of the German economy.

A last note: recessions are generally accompanied by deflation, though there the cause-and-effect relationship is complicated.
>Now add the Chernobyl TV series on top, it will be replayed and memefied everywhere a plant is proposed.

About half an hour into the first episodes I was like, yeah I get it these people lie a lot to save their own skin. And while I'm not exactly crazy about physics correctness, the way it radiation was dramatized was just unnecessary, a pregnant woman isn't suddenly going to die or get birth defects from standing next to someone was exposed to radiation. The show gave the whole incident the flair of a zombie apocalypse.
I really enjoyed the acerbic and colorful style of this article, but wouldn't have enjoyed it nearly so much if it were all style and no substance. He's clearly knowledgeable, though I know the style of writing isn't the usual fare for HN.

He's correct that really good businesses tend to start during recessions. Starting a business during a Roaring Twenties style economy when you could literally support yourself with a ridiculous idea like selling pet rocks will not test your business model and help you find its weaknesses. A la some African saying to the effect that "Calm seas don't produce skilled sailors."

I learned a lot and I am a bit envious of his acerbic wit. I feel like that's more acceptable from a man, but sarcastic contempt was pretty much my default as a teen and I sometimes think I've become a bit too PC over the years.

it'll be super expensive to hedge -- the higher the volatility of the underlying asset (here, the number of people who pay for a desk or whatever), the more valuable/expensive an option on that asset is. but I also don't think it makes a ton of sense. in effect, WeWork would reduce their cash flow growth, with payments going towards hedging. their entire pitch is that they are a fast growing company, which justifies an insane multiple, any hedging would reduce that risk.

you don't hedge against decreases in demand via financial instruments, instead you:
1. hedge against decrease in demand through diversification of services; if wework sells some property management software (for example) then that might be more recession-resistant than their actual leasing business.
2. hedge against decrease in demand through long-term contracts: getting IBM to sign a 10 year lease (for example) is usually a safe bet that you'll have a tenant through the recession; on demand hot desks are much less safe
3. hedge against cost increases using financial instruments: most corporations doing hedging are hedging against commodity price changes, e.g. airlines buying oil futures or mcdonalds buying beef futures. similarly, wework might buy kombucha or aluminum cup futures, but there is no derivatives market for on-demand desks :)

of course, there are different perspectives on this. matt levine has a really interesting column about the different philosophies of where diversification belongs, at the corporate level or at the investor level: https://www.bloomberg.com/opinion/articles/2019-04-09/ceos-l.... my finance classes were relatively recent so you might be able to tell my bias.

lol "destroyed"? "merciliessly"? I love it in a world where a lot of bad shit goes down only the stuff that involves women and sex is automatically hyped up to the most important, even more than genocide. So every woman automatically gets a sort of 'supercopyright' where she can decide 20 years down the line what happens to every single copy of certain 'embarrassing' images of her across the entire world. Why not other types of images? I mean Bush puking on the Japanese PM was pretty embarrassing. Oh so because its a woman, even though she openly and knowingly released the pics in public, its still special. Man we really are still Puritans, still pedestalizing sex and the honor of our ladyfolk.
