"Z-Berry is the smallest Z80 based computer ever built."

Not to be pedantic, but the Timex Sinclair 1000 of 1981 had a lower chip count than this computer.

Take a look at the board:
http://oldcomputers.net/pics/ZX81-mb.jpg

And it even includes the RF modulator.

Of course, the Z-berry is a far more powerful Z80 computer.

Ready to run again all your CP/M 80 programs?

PS: What would have RULED would be to include in the Z-Berry a socket for the SID* sound chip or at the very least two POKEY* chips.

* SID: Commodore 64 sound chip. POKEY: Atari 8-bit (800/400/800XL/etc) sound chip.
This is thorough and overall really well done, but after reading through Part 1, I can't help but trot out Brian Cantwell Smith's "The Limits of Correctness" https://www.student.cs.uwaterloo.ca/~cs492/11public_html/p18...
> this universe has the widespread concept of a "wage slave"

"Wage slave", as I recall, was adopted into cyberpunk literature from pre-existing 1970s-1980s American culture, which itself got it from the Marxist critique of a core dynamic of capitalism.

Examining Bitmain’s Press Release

What is unique about the US historically is that they have always claimed to be spreading freedom while frequently doing the exact opposite. Of course it is really just a new twist to the old western excuse for invading: we are civilizing your, or: we are bringing christianity to the poor masses.

But this isn't unique nor Western. The Persians invaded Greece. The Chinese invaded Tibet. Great Britain at the height of its power was screwing over China and India and that's maybe even more impressive from a power projection standpoint considering just how small England was and how much less technology they had.

I don't believe that you actually think that Americans are somehow different from the rest of humanity. Out of 300 million people there are a lot of Americans who don't agree with everything their country does.

There is good and bad, and to act like the US is some kind of extreme outlier is prejudiced and not honest about history. It was less than 100 years ago that every European power had colonies and it was less than 75 that the Japanese and Germans were murdering other peoples in the service of empire.

It's a human thing.
I agree with you on most parts.

However I come from a private "engineering" school focused on computer sciences (named Supinfo) and there's some others (Epitech / Epita ) that though they don't deliver a engineer diploma (as per the law-regulated definition of engineer) but rather a master diploma (but that you can name "engineer in computer science" or somekind of trick like that and the schools play on that to attract student), actually have to my opinion, provide a decent education.

I learned assembly, C, logical gates and how to build a 1 bits processor.

I then learned HTML, and SQL, and then PHP, and some basic of algorithm (though no data structure courses, I learned only years after being graduated what was a quick-sort/merge-sort)

But I also learned management (how to hold a meeting, how to manage conflict) and project management (Gantt-diagram, Agile and Scrum) and some basis of ITIL

And even more related to the entrepreneur-ship world I had lessons about copyrights law, labor laws, patent laws , as well as finance course (what is an asset active/passive, what is the difference between giving yourself a salary and giving you shares etc.)

However I have to admit 10 years ago, I wanted to be a monkey-coder and thought the management and finance lessons were bullshit for people who were not good enough to code and still needed a job.

So I have to say the school totally prepared me for the "startup world" (and with 30 campuses in France and ~5000 graduated student a year, quite some others were prepared, though they were maybe with the same mindset as me).
Most of the comments here already talk about UX or other standard 'issues' with Snapchat, so I wanted to raise a different one—

On Snapchat, there isn't much to do once you're done seeing your friends' snaps.

Instagram has an amazing discoverability feature, plus, you can go around visiting other people's profiles as long as they are public. Ditto on FB, where there is an endless list of things to do and see and explore without interacting with anyone or letting them know of your actions.

On Snapchat, there is nothing of that sort. Snaps are temporary, Stories only stay for 24 hrs, and you can't see anyone's content without them getting a notification (last I checked).

Sure, this prevents 'stalking', but that comes at the cost of engagement.
Is CloudFront down?
https://status.aws.amazon.com

AWS CloudFront seems to be down in Europe and parts of the US for at least https://cache.nixos.org.

The AWS status page says "Elevated SSL Handshake Failures - 1:36 PM PDT We’re investigating elevated SSL handshake failures from our CloudFront edge locations."
There is no collaboration between VA and the streaming services. This is a rogue third party service that is not sanctioned by any of the streaming service providers.
Why are we talking about Fourier series? Uncompressed digital audio doesn't need them, it just records the raw voltage level samples. You still can't produce a perfect square wave, but there's no reason you shouldn't be able to reproduce whatever wave was provided as input (which by definition was produced by something), other than hardware limitations of the playback system.
Worth pointing out that tech stocks are down heavily in June, esp. consumer tech [1]. Some portion of this decline is unrelated to investor confidence in Snapchat relative to FB etc.

I see what you're saying, the consequences don't outway the benefit of breaking the law; Congress can solve that through tougher penalties. That said, I feel confident the answer is not putting MORE people in Prison, especially for civil cases. The US already incarcerates far too many people. It's out of control as it is. [1] [2]

[1] https://en.wikipedia.org/wiki/United_States_incarceration_ra...

[2] "Comparing some countries with similar percentages of immigrants, Germany has an incarceration rate of 76 per 100,000 population (as of 2014),[25] Italy is 85 per 100,000 (as of 2015),[26] and Saudi Arabia is 161 per 100,000 (as of 2013).[27] Comparing other countries with a zero tolerance policy for illegal drugs, the rate of Russia is 455 per 100,000 (as of 2015),[28] Kazakhstan is 275 per 100,000 (as of 2015),[29] Singapore is 220 per 100,000 (as of 2014),[30] and Sweden is 60 per 100,000 (as of 2014).[31]"
Canada is an amazing deal for US companies to open remote offices and save 50% of their employment costs. Forget the numerically lower salaries - factor in the dollar difference (20-30%) then factor in healthcare savings.

Plus we speak English and share a lot of cultural similarities, and the time zone difference in Toronto is only 3 hours. Why more companies aren't doing it I just don't understand.
This rate of change thing you are implying doesn't really exist, right? Can you provide a reference?

Once the cancer has spread outside the pancreas to other organs then it becomes more easily detectable, and symptoms show. By then it's throughout your body and you can't easily remove it.

As long as your function is idempotent, I suppose.
Fun fact: Y2K is still an issue in some old systems. Some, instead of going through and properly fixing the whole system, just bolted on logic to assume if the 2 digit year is less than say 30, assume it's 20xx and if it's 30 or more, assume it's 19xx. This saved the time of having to update the storage layer, but it means that they're in for a surprise in the future. Then there's the 2038 problem.
But the salaries they publish in h1b are done so to prove that they are not doing a job cheaper than a comparable American citizen could. The expectation is that h1b's statistically represent the normal curve. (Or are higher)

I think it should have a good representation of expected salary.

It's almost always safe to ignore any 'Wonder Teenager makes Breakthrough' articles if the field of the breakthrough is hard science. The likelihood of a novice inventing something novel in a field with tens of thousands of PhDs is so incredibly low that the breakthrough is almost guaranteed to be overstated.

George Church (and others) looked at Andraka's preprinted paper and wasn't exactly blown away. The cost and speed comparisons were wrong, the sensitivity and specificity were both too low to be clinically useful, and like you pointed out, mesothelin has some intractable problems when trying to diagnose tumors.

One of the most annoying habits of computer professionals when talking about security is how we object to every idea by showing how a stupid/lazy end-user could render it useless.

It's not that users will never do that: it's that users can't get into secure habits if we paralyse ourselves into not providing reasonable tools.

I've used a dual cpu AMD Bulldozer for years (and still do), it's been rock solid and the 32 threads really helped with certain workloads. At the time the equivalent from Intel would have been far more expensive.
It's good to read the articles, but that's not the part I objected to in your comment. I objected to the idea that there is always someone claiming bullshit and it's white noise, or that upvotes imply not-bullshit.

In other words, you can get a good idea of whether something is bullshit without reading, but you should still give it a look anyway. I agree with part of what you said, but not the other part.

Maybe a simple metaphor for what TLA+ can be used for would be to think of a "game" consisting of a "board" and "moves", and then exploring what game states can be reached?

So the question in a specification is deciding what the board looks like, what the legal moves are, and what properties you're interested in. Then model-checking is exploring the game tree to some depth to find out if there are move sequences that will reach interesting states.

You wouldn't write a chess or Go-playing program in TLA+, but most discrete systems have smaller trees than that.

It seems like it would reasonable to compare this to QuickCheck-style testing or fuzzing, except that it's entirely done in a different language.

>In other words, "just be positive"?

For incredibly poor interpretations of the phrase "just be positive"
Fair enough. On the face of it I don't disagree with your points. I should have expressed myself more clearly from the beginning.

Wish you'd look at it from the other direction though. Skipping reading articles because of assertions of the currently-top comment's dismissals is a recipe for groupthink and circle-jerks. Upvotes at least reflect a general consensus that an article has some merit. The top comment may indeed credibly refute an article - but the attitude of "I don't even go to articles anymore" is not that of someone seeking the truth. Instead, it's that of a lost soul looking for his "team" to join, and avoiding any contradictory information.

"Don’t Spend $40 to Flash an LED Over the Web"

The new Pi Zero W's are $9 and the include wifi. I used to use arduinios or MSPs for things because i didnt want to "waste" a full pi. But I mean, $4 savings with these NodeMCUs? vs. the platform I already know how to use that's a normal computer that happens to have trivially easy to use IO pins? For one-off type projects i just don't see how it's worth it for me. I'd rather spend the four bucks and skip ahead to the interesting part of the project.

Imho the better thing to consider w/ pi is that even the Pi Zero W consumes a decent amount of power. So for some projects, that really matters.
> but other than "it's everywhere" is there a more solid reason?

IMO you'd need a pretty good reason not to use the de facto standard, even if it's arbitrary. IIRC it has something to do with the width of teletypes
Most of the behavioural patterns are eased by fp techniques like lambdas+currying and adt/pattern matching (visitors are well known losers).

The structural patterns are however much more a pain in fp while they feel natural in oo. Facades and decorators need type hiding that's only nice(r) with existential types.

The creational patterns are a mixed bag. Builder, singleton fit with fp, Abstract Factory fits with oo and factory methods with both.

What do you think? How are the oo patterns improved by other techniques. Though a lot of those patterns are probably for C style oo.

> I'm all about open-source, but I wish people wouldn't focus on how companies should do it because it's good for them financially

1) Why on Earth would a company spend a considerable amount of resources on doing something that isn't good for them financially? That's their thing, and in the whole scheme of things seems like good separation of concerns. Companies make profits. Other things do other things.

2) Figuring out how to measure the productivity of an open source project from a single perspective is a positive thing. We know that the externalities of the large profile, well-funded, open source projects feed back into their participating parties positively, from those funding them to those participating out of pure interest. Some of the big companies can even account for this in some way, but we also know that it's hard to fully account for the benefit.

One explanation for why a company might fund open source, given to me by someone working for Microsoft to the end of funding open source projects, is that open source generates the highest degree of reusable code. My guess is that allowing disparate interests to define a thing will net you a more nuanced definition than otherwise. Time preference will always be a thing though. Often you need to be fast more than you need to be correct.

Oh you have no idea. I was walking through super-liberal downtown San Francisco a few years ago with my wife (I'm caucasian, she's asian) when some officious-looking guy walked up to me and said 'I'm going to have to issue you a warning' like he was giving me a traffic ticket.

I wasn't sure I'd heard him correctly and was about to cross the street so I did that and then looked at the piece of paper, expecting maybe some some religious admonition. Instead it was a fake legal document saying I'd been identified as a 'race traitor.'

Speech like this is arguably not constitutionally protected by the first amendment, despite popular misconceptions to the contrary. But breaches of the peace have to be enforced by the police; there is no private right of action. This leads to obvious problems where ethnic minorities or members of other protected classes are subject to abuse and local authorities are unsympathetic, a tension reflected in the state/federal legal divide.

Unless I'm missing something, I don't see how HIPPA would have anything to do with this. It only applies to "covered entities", so had the initial disclosure happened in the US, the leaker most likely would have been implicated, but HIPPA would not apply to Uber people (unless, for some reason, Uber is a covered entity).

If you want to do anything "linuxey" with a Chromebook, don't you need to use something like Crouton and install a whole different distribution anyways?

Is it even possible or simple to install ChromeOS on a Pi? Most projects related to ChromeOS on Pi seem to be dead. There's FlintOS, which had it's last update last month, but in the release notes:

> We have disabled the root password briefly for improved security, subsequent releases will have a better system to maintain security and allow users root access if activated.

There's also ChromiumRPI, which hasn't been updated in a year and does not and will not support wifi.

Also as far as I can tell, none of them can play Netflix unless you're on a real Chromebook. I'd say it's fairly "hard to use".
Mint+KDE is pretty good. Sadly the akonadi junk needs to be sabotaged.
> But even worse than that, end-to-end encryption is off-by-default, and users must opt into it. Why?

Because it is unusable. It has no synchronization between devices, only 1 device to 1 device. And if you accidentally closed the chat, you have to verify it again. You can't store trusted key fingerprint.

It is not suitable for mobile devices. Secure chats are like OTR, but with bad crypto. Signal and WhatsApp are the same protocol as OMEMO, originally designed for Signal.

And yet Telegram is associated with terrorism more that, e.g., WhatsApp.
You clearly have failed to see the absolutely mindbogglingly behemoth Facebook has become behind the scenes. The amount of personalized data they have surpasses even Google's at this point. I fear for those that don't take Facebook seriously, and not just in the financial sense either. Data is devastatingly powerful, and with power comes the potential for both great good and great evil.
This is an incredibly flawed argument and comes from an incredibly flawed perspective on “worth”. The most valuable thing Facebook has is distribution and that is absolutely worth A LOT. Not only that, but it has unprecedented global distribution backed by engagement numbers that keep the value afloat. You’re trying to impose the values of a physical goods economy onto one that is purely digital and the concepts don’t translate.

Whoever that "someone" is, probably isn't as experienced in the markets as you think.
