I guess it's about the 6502's more RISC-like philosophy, which made it a bit more cumbersome to program in assembly code (even though the resulting performance was mostly similar to the Z80 because the 6502 could do more things in fewer cycles).

Even with the whole 'extended register set in the zero page', the 6502 didn't have convenient features like 16-bit math, memory block instructions, and even 8-bit math was less convenient (e.g. no separate add/adc, sub/sbc instructions, so you always had to clear the carry flag before a math operation etc...)

But I think this didn't matter for porting the operating system CP/M itself to 6502, the actual problem was binary compatibility with applications, and the Z80 was backward compatible with the i8080 (as long as only documented instructions were used).

I guess being compatible with the i8080 (and CP/M 'office software') was the whole point why the Z80 was even created (as an i8080 killer), and that it was as successful as it was.

Fascism Is Not an Idea to Be Debated, It’s a Set of Actions to Fight
America is doing everything it can to run a Prohibition War on Prostitution by driving it further underground and over-criminalizing poor and vulnerable people (with the other 8 million in prison, more per capita than any other country, save Seychelles, and possibly China with the Uygur concentration camps). The moral panic "war" is lost: regulate and let people live. It works in the UK and Europe. Oh yeah, American porn is somehow legal prostitution with a video camera because it's "art" and "professional." Consistency fail too. Maybe start making lots more "porn" that satisfies legal requirements and then the oldest profession becomes legal.

If a food business is making close to minimum wage in value per worker, then they are going to fail anyway. Last time I was on minimum wage was being a kitchen porter, many moons ago. If minimum wage had gone up, the job would have not changed at all in the slightest. I mean, they were not going to serve the food on dirty plates and none of the chefs or owners were going to stoop to cleaning anything.

If you ever lived in the actual USSR, you must also remember how poor average people were, how hard was it to find and buy anything decent, or simply anything. Including food. Want a piece of meat? Spend two hours in a line. Want a piece of Bologna sausage, or butter? Here's your food stamp for a minimum monthly ration.

USSR just did not have enough resources to properly feed everyone using planned economy. It had to admit the very smallest pieces of market economy (sell apples from your orchard, don't go to jail) to keep people somehow fed.

I wrote code used to design hardware semi-automatically. The size and complexity of the tinest chip make it impossible to check the finished hardware perfectly.

But even if you somehow managed to check it once, nothing proves it's going to be unchanged for years and years you order it.

I interviewed with Amazon a little over a year ago and my experience was quite the opposite of what was described in the article.

Amazon recruiters approached me first on LinkedIn and invited to one of their off-site hiring events in Europe. I didn't feel like interviewing with them back then as I wasn't sure I could pass but still decided to try.

Communication with the recruitment team was surprisingly flawless - I didn't have any issues with timezones (I was based in Europe, they were from Seattle/Bay Area), there were some last-minute changes that didn't affect anything/caused any trouble. HR provided me with tips on how to pass the interview and shared some online/offline resources on how to get prepared - they also put a lot of stress on their company principles.

After the initial tech screening and a Skype call with one of the recruiters, I was invited to the hiring event. Amazon rented the whole floor on one of the top hotels in the city, all the candidates were assigned a room and the interviewers came to you - 3 interviews for algorithms/data structures, 1 for system design. The organization was really superb, interviewers were very positive and eager to share their experience.

In the end, I didn't get an offer, but I'd say I'd definitely try to interview with Amazon again.

PS. From what I read here, maybe I was just plain lucky to have a positive experience interviewing with them :-)
How to Buy Ethereum (ETH): 2019 Guide to Investing
It's not like you stumble over UB in your daily work in C/C++, you know it exists, you know which areas to avoid, you compile and test on the 3 "big" compilers (gcc, clang, cl.exe). On clang, test with UBSan enabled.

UB isn't "crazyness" it's just a detail to be aware of.

A compiled binary that worked correctly won't suddenly run into undefined behaviour, that can only happen if you upgrade compiler versions or change compilation flags. But this only happens while the application is still actively developed and tested.
Nowadays you can do the same with random S3 buckets of various companies (:
And for every dignified refusal to take that abuse of an interview, 100 spineless moluscs will happily suck up to it.

There's homeless people living on the sides of highway on-ramps in the Bay Area. 30 years ago, this wasn't a thing, but it's gone too far: not that the people need to be busted up and bus-ticketed elsewhere, but rather civil society has broken down and failed to provide for people.
Looking at this account from a meta-perspective I feel reminiscent of fraternity pledgings. A certain percentage of applicants suffering through a similar experience while getting for whatever reason an offer in the end will feel by principle of cognitive dissonance especially grateful and devoted to Amazon. You want to be a part of this shiny company? Here you go - take a sip from the puke bucket! And they do it thinking that place must be awesome because why else would you endure that bullshit ceremony? Finally you're the one passing on your trauma on fresh aspirants.

Two tools I've found useful for getting text on page:

* https://getcoldturkey.com/writer/ -- just a very simple full-screen text composer

* https://otter.ai/ -- an app for doing transcription of human speech. I find it very useful to go to a quiet area and talk into it and then use that as my very rough draft of my thoughts. You'd never use it for stenography, but the quality is good enough to make it clear what you meant to say.

and if your voice of self-criticism says "that seems like a crutch", reflect on the fact that you are a tool-using human who will probably wear shoes tomorrow and many days thereafter.

> If people really want a pure, statically typed language Kotlin is pretty good and has less impedance mismatch with Java.

I see this the other way around: Java genuinely has eaten most of the good parts of Kotlin, because Kotlin is positioned as a small enhancement over Java rather than a language that brings major improvements as Scala does. Adopting Kotlin means paying much the same cost as adopting Scala, but for much less in the way of benefits.

You really don't need to go very far to get into UB instead of implementation defined: signed int overflow is already UB and the program is permitted to do literally anything if you ever accidentally make one of your ints too large.
But that would completely ruin the article, if it were OCR'ed.
You can still walk away, but the key point is that those who do not want to walk away will still hear differing (to theirs) opinions.

on one end, there's a "developers" shortage, but on the other, all companies are funneling potentially good engineers through processes designed for the "interview" experts.

If there genuinely was a shortage could any company get away with these ridiculous practices? It only makes sense if there is both a glut of candidates and of existing employees with lots of free time on their hands.

During the dotcom boom when there was a genuine shortage an interview was a phone screen, a couple of hours onsite then “when can you start?”. Companies couldn’t shovel workers in the door fast enough!
1. I belive I'm Shadow banned, but who cares, and here goes. (There's a positive side to being banned on HN, but that's another story.)

2. If anyone hears me, yes, it would be great if all homeless had access to good Psychiatric help. And what's help good these days?

3. The chronic homeless I know just want a legal place to poop, and pitch a tent.

4. Most aren't seriously mentally ill; just the end result of a careless, brutal economic system. A system that fails many of us, especially the ones without a stable support system. What's that support system? Usually a caring family member. That caring family member that is always left out of the "I'm a winner" speech.

5. Rich boys can find themselves in college, and the job market.

6. Poor boys have one, or two chances.

7. A mental/physical hiccup can bring a poor boy down quick.

8. I don't want to debate, but we need areas of land that people who don't fit in can camp. We need it immediately.

9. Counties are using that "break on the glass theory" to harass poor souls to suicide, and worse. Worse is deficating on your streets? You don't like it, nor do I, but where are they suspose to relieve themselfs?

10. We need free plots of land, and bathrooms for the homeless. I've never heard a homeless person ask for much. My buddies just want to legal place to sleep, and a legal place to relive themselfs.

11. We are currently living in a society where everything is basically illegial. 100 years ago most people were basically homeless, but they had hope, and weren't harassed, vilified for not fitting in. Those days are gone, and we wonder why they do drugs?

While we found Pandemic Legacy to be entertaining, anecdotally I do not know a single person that decided to purchase season two (and we won't be playing it either).

The game is "play once", and you don't get a chance to try alternate paths through it without purchasing it again. It was decent entertainment, but terrible value for money compared to... all other board games. Edit: it doesn't help that there are dozens of pandemic games and the concept was bled dry years ago.

There’s Latin-1 which gets you full coverage on many European languages and almost complete coverage on several others (e.g. French uses œ, which it doesn’t have but French readers will be able to understand if oe is substituted).

The problem with Latin-1 and other 1-byte options is that, unlike ASCII, they aren’t forward compatible with utf-8, which is the emerging de facto string exchange encoding. For a stand alone video game, maybe that doesn’t matter but for anything network enabled it can be a big issue.

It seems to me, that legalizing prostitution would be at the top of the issues list for feminism.

Most of the arguments made in support of legal abortion could also be made for legal prostitution.

Furthermore, there is a fair amount of research indicating that legal prostitution reduces occurances of rape.

Although I suppose it would increase “liquidity” in the market, and reduce the value of sex to a certain degree.
Read the news articles on the subject. There's a vast number of gainfully-employed people whom don't wish to fritter their relatively meager earnings away on techie-inflated rent. Most people in the area cannot legitimately afford to live there as they would be spending more than a sensible amount on housing because they can't ever hope to earn enough to be considered middle-class. Still, the area needs janitors, cooks, teachers, bus drivers, human resources and more non-techies whom rarely make much in a normal American city. Instead, they make some sacrifices to keep more of what they earn and opt-out of following the other lemming off the cliff into perpetual debt peonage.

The Z80 was designed to be i8080 compatible (for the documented/recommended opcodes), so that it could run unmodified CP/M software.

The Z80 instruction set basically added new opcodes where the i8080 instruction set had gaps or redundant opcodes (e.g. the i8080 had 16 identical NOP instructions, and 4 identical CALL instructions, but only the lowest opcode was recommended to be used, if one of the redundant opcodes was used, the program ran on an i8080 but not on a Z80).

Can you elaborate a bit more about your usage of GitLab CI/CD for model management/development.

I wrote a self-hosting (if you're very patient) compiler for the 6502 and Z80 a while back. Both are a bit of a shock if you're used to true 16 bit arch architectures. I did a couple of writeups on the problems of doing basic arithmetic in them:

http://cowlark.com/2018-02-27-6502-arithmetic/index.html

http://cowlark.com/2018-03-18-z80-arithmetic/index.html

The 6502 is more orthogonal, and while each instruction does less they're very fast; the Z80 is fundamentally more powerful but weirdly inconsistent, terrifyingly slow, and the unorthogonal register system means that you spend half your time shuffling registers.
"however, when it happens in market economies, it is not caused by planning for greater efficiency (saving money)."

I think the author addressed that, writing:

> "For the capitalist or even market-socialist firm, there is in principle a simple objective function: profit, measured in dollars, or whatever else the local unit of account is."

"I disagree with that .. I think the objective is"

I'm not sure what you disagree with. My incomplete summary? The author also goes into detail about the problems in determining the objectives. I mentioned them in passing in my last line.

"In theory, perhaps"

Well, yes. That's because it's a response to the theoretical statement you wrote: "You can have an efficient system but it's robustness (ability to withstand a failure or adapt to change) will be very low."

Do you have any evidence that this is a universal statement?

Anyone worried about possible environmental catastrophes as the result of greenhouse gas omissions must certainly be wondering what can be done to include that robustness factor in a market economy.
