One of the common things that mainframes and COBOL are used for is financial systems, and that means a lot of fixed-point decimal data. So suppose you have a file containing an account number and a balance, like '9876543210 000000123.45', and you want to add to that balance.

In Python, once you have that record read in, you have to split it apart by some means. That takes CPU work. Python will then store the pieces as new objects, and that takes CPU work. Then you have two strings, and one of them (the balance) must be converted to a number that can be operated on, more CPU work. Then you can do the math, using the Decimal module, which is more work. The result then has to be converted back to a string and written back to the file.

COBOL, on the other hand, understands record formats, understands decimal date, and knows that the hardware supports decimal data. So the same task (add to decimal number in record) that on Python may take many thousands of CPU instructions can be done in three: PACK (convert printable (zoned) decimal number to packed decimal, ADDPACKED (perform the addition), and UNPACK (back to printable number). And those three operations are performed in dedicated decimal hardware in the CPU.

The important thing to remember is that in the mainframe world, not only is the hardware priced according to the performance of the machine, the software is also. This is why there are so many performance levels (over 100) to choose from. Users naturally want to buy the smallest machine they can get that will handle their workload, and they aren't interested in wasting any processor power doing things not absolutely required by their business needs. For this reason, you won't find any mainframe shops running traditional mainframe workload in a language like Python.
Yes Ember-Data was great thing to have in Ember, something I miss from React ecosystem. In the early days was a bit unstable but now it's super stable and flexible (serializers/adapters customization etc). I think there should be an initiative to get it out of Ember so that you can use it with other projects as well.

I agree 100% and think that OP __should__ absolutely be able to approach a coworker and mention this sort of thing. But, in the OP's interest (assuming OP wants to keep job in good standing) I made my recommendations.

"Business setting" sucks. I'm in a "family-like" work environment where I can approach anyone from CEO to Reception with ideas, feedback, or ask for feedback. It's fantastic. I wish all companies were like this. Unfortunately, that's not the case.
>What happens to the mom and pop coffee shop or the grocery store that charges more than Amazon Fresh?

Coffee shops aren't known for being places to get cheap groceries; they're places where you get fancy drinks and/or snacks and hang out and talk to your friends or use the WiFi. In other words, coffee shops are selling an experience, not a fungible good.

If a coffee shop goes out of business because of an online seller, they must have been offering a really lousy experience.

In theory you could use something a secret sharing algo[1] to distribute the key among a set of people. It doesn't have to unanimous either. If we designate a 7 judge panel to be in charge of deciding who gets access, we could give each a piece of the key and a 4+ majority could unlock the key.

Unfortunately it's wishful thinking / cipherpunk porn to imagine a world where that actually happens.

In reality the videos would probably be stored in plaintext, there wouldn't be viable/tested backups of them, there would be no log of who has access to them (the log would exist but it wouldn't log actual access), an insane number of contractors working for the department of justice would have access to all the videos (though most wouldn't realize it) rather than it being on a need to know basis, and just about every other infosec / PII issue you can imagine would apply as well.

5 Talks to Learn About AI
You're absolutely right. There are. Blowhard professors, in my opinion, are the ones that prioritize recognition over research. There's a thread in certain research circles that would eschew any such recognition in the hopes of putting their work on a pedestal in place of themselves (e.g., the Bitcoin people, again in my opinion).

Companies are creatures of the state, created for the public good and protected by the laws of the land by the citizens of the state. Companies are permitted to take advantage of the legal and regulatory mechanisms put in place to encourage growth and innovation. Companies are permitted to employ members of the population, who are often educated based upon the good will of public funding. Companies don't have to worry about employees after they are "used up" and are broken or too old to work or are problematic. All of these items are provided as the environment for the company, and the citizens of the state collectively are the ones who have made it possible.

Therefore, first and foremost, Companies must serve the public good. The rights/interest of investors can be seen as a secondary interest. Not that private interests aren't crucially important; however, out of the gate there is a balance of public/private interests -- presenting it otherwise isn't correct.
I'd say this link is very indirect; in fact, a lot of structure in companies exist solely to decouple the two. On the one hand this is sound - you want the end result to be independent of moods and dramas, both internal and those of lives of individual employees. On the other hand, this decoupling is what makes consumers totally unaware of whether and how much employees are abused in the process.
Also, when you do use Redux, as in your nesting example don't pass props through components that don't have any need for them except they propagate the prop to someone else. It's absolutely fine to connect() a component deeper in the hierarchy. Passing everything down is an anti-pattern with Redux, separation of concerns still applies and the props of a component defines the API, don't clutter that API with unrelated things.

Components only receiving props that they themselves need has kept things clean in our massive codebase, and allows you to effortlessly move things about and easily re-use components wherever it makes sense.
As mentioned elsewhere, though, it's not a 3h break, but 3 hours closed to the public. Usually 1-2 of those hours is back office, maintenance, inventory, accounting, etc (well, for banks I'm not sure, but for independent shops that's definitely the case, usually at least)
Yeah. My biggest problem with attempting low-carb is that X+rice and X+pasta and X+bread are all delicious for almost any value of X, while nearly all values of X on their own are fairly unappetizing. Beans and rice? YES. Just beans? I mean, I can, but I'll hate every bite. Veggie and tofu fried rice? Yes yes yes. Veggies and tofu alone? Uhhh... must I?

The exceptions tend to be expensive and the kind of thing that makes me feel kinda gross after eating more than a few bites of it anyway. Steak, say. Most meat on its own is like this, really. Just cheese. Veggies and cheese. Meat and cheese. Uck. Veggies and meat can work out OK on its own but, again, kinda expensive and still not as good as if you threw in some wheat products.

I have a suspicion that food without carbs being fairly unappealing is part of why many of the people doing keto lose weight so quickly.

Going vegetarian—and probably even vegan—would be far easier for me than a keto diet.
What is this journalists issue with planting tweets in the middle of an article? It looks really really really dumb.

You don't get it. People don't want good proper science-based long-term solutions, they want fast & effortless solutions (meaning no sweat). People don't want to change their life, they want to throw money at problem to see it solved. Well, our bodies are not some TVs or radios. One day, sure, but not now, not during this century.

That's the only reason why so many idiotic diets exists (some are OK, but most just don't work for long term or are outright absurd).

Right, and also, a good part of why credit cards have 2-3% overhead is essentially insurance against chargebacks. I'd rather pay $51 for groceries every week than $50 for groceries plus a risk of irrevocably losing tens of thousands of dollars at some point with no warning.

If cryptocurrencies think that they can provide this service for substantially cheaper than 2-3% (note that this is an additional service on top of simply making the transfer happen, so mining fees aren't the right thing to compare), that sounds awesome, but also I'd like to understand why it's possible.
I've been the person who wasn't performing to expectations, and I've been the Manager who has had to tell people that they haven't been performing to expectations.

In my case, when I wasn't performing well, simple honesty would have gone a long way: it was simply a case of I didn't know. "Hey, Ian, you know, there's this python tool that you can run called pylint that makes sure that your python code meets community standards before you commit it," (it was my first real exposure to python) or, "spaces not tabs," (first real programming job @IBM before being rolled back to a hardware project). I was fortunate enough to have mentors and leaders who provided me with books, challenges, and guidance to make me a better programmer -- while doing so in a positive way (not a PiP: those are about as demoralizing as they come, yes, I'm looking at you, CollabNet) to make me a stronger programmer and a better person.

When I was a leader, I tried to move it to a non-threatening setting: lunch or coffee. I tried to take the steps that were used on me that I thought were positive -- You are part of a team, and we don't want to leave you behind; here is $100 to spend on books, and here is a list of books that you should start out on. Here are some programming challenges to get you started out. Here are some internal mentors who can help you. Don't be afraid to reach out to any member of the team -- don't feel ashamed. We are a team. When one person fails, we all fail, but, when we succeed as a team, each one of us succeeds.

Is this perfect?

Anecdotally: yes. I've heard from some long distance runners that the ketogenic diet makes it easier to endure exercise. Your body runs on fat, so as long as you have stores then you can keep going until your muscles start to waste away. There is also anecdotally no "wall" that you need to break through, as this comes from exhausting your muscles' supplies of glycogen.
> and Statists

Your bias is strong, it's far more likely you're the one with misunderstandings than the OP. The unbiased don't go around calling people statists; nation states are the norm in the world, they're properly just called people. As the anti-statist and the one who isn't the norm, the label more appropriately belongs on you. Humans are tribal animals, always have been and always will be, nation states are merely the current expression of this normal natural human behavior.

Bitcoin is simply not attractive to the ordinary person because they don't have this anti-state bias that makes it so attractive to you. The dollar is incredibly stable, that stability comes from a central authority who actively manages the currency to keep it so, and people like it that way. As a currency, Bitcoin is terrible and doesn't come close to approaching the utility of the dollar. Bitcoin is little more than a speculative tech commodity attractive to a small minority of people who think they can either make money or escape the state. It has a place, a small one.
Not the OP, but I've written assembly in our codebase for:

* First stage initialization

* Interrupt prologue/epilogue

* Bitbanging where you want deterministic cycle counts

* For using the FIQ for very high priority interrupts. It has it's own registers partially banked, so if you stay in r8-r13 you don't have to save and restore state at all.

So we don't use assembly for magic go faster juice, but instead when there's a coding constraint that we can't easily explain to the compiler.
The graph layers look wonderful, I'm happy to see they have progressed so far!

The combination of Arango's new capabilities with Graphistry should be interesting. So, if Arango graph users are interested in trying GPU visual graph analytics for looking at more data at a time, our team is happy to share access to http://github.com/graphistry/pygraphistry . Likewise, investigation teams digging daily into event & entity data (security, fraud, patient journey, ...), we are piloting our visual playbook automation & interactive investigation layer with medium & large enterprises, and we'd love to chat about that as well. Either way, ping info@graphistry -- this sounds like a great match.

Even if the primary service itself was compromised, it would be possible to have an automated dead man's switch running on an alternative service that would alert the world that you were being held incommunicado.

Of course, failing to disclose the switch to the authorities and thus allowing it to trigger could be considered a violation of a court order and lead to punishment.

The clever thing is that they took it over and for one month monitored it without the users knowing.

Everyone on obfuscating their persona with Tor and bitcoins, still had to enter their postal addresses on the website, to receive the goodies.

Agreed, at my job I'm now actively campaigning against LabView (and Matlab) for application development. These projects turn out productive at first and invariably turn into unsupportable messes.

What's the right platform for "embedded systems" is debatable. A true bare-metal app has different requirements from something running on RPi or Beagleboard.

I didn't name the obvious problems because they've been talked over to death at this point, typically in that most-upvoted first post you mentioned initially.

I think the largest issue with Bitcoin is precisely what you probably admire it for, judging by your description of its detractors: I don't think the average consumer wants an unregulated currency. People like having a central authority that enforces laws around their currency. People enjoy the benefits of a dollar that doesn't fluctuate wildly in value. People enjoy the conveniences of modern banking systems.

There's a tendency for libertarians to ignore very obvious examples of contradictions in their world view, because any of these examples can be dismissed using random ideological purity tests. Namely, the idea that the market is entirely separate from the government, or that a government formed by (often very imperfect) representative democracy or even brute force is any less pure of a "force" than market forces.

Modern financial systems developed largely because people wanted them. Consumer protections laws were implemented because people voted for them and would be very upset if they were taken away. People who step into voting booths are still "rational actors". People who disagree with your world view (just about literally everyone) are still rational actors.

At the end of the day advocates of cryptocurrency have tried everything to get people to start using or accepting Bitcoin and no one has, despite no real government intervention. Hell, the whole point of your original post was to lament that the most popular opinion is that cryptocurrency is dumb. The market has said no, why have you not started listening?

(Also: Mining is massively wasteful. Transactions are expensive. It's overtly complicated and unpleasant to handle. A lot of people lose all their money because sites get hacked. Also, all the issues brought up by this whole forking incident.)
Admittedly I'm not extremely advanced in embedded design, and work more on prototype r&d than production applications with really high stakes (life safety, expensive equipment failure)

I've always been really repulsed by labview for a few reasons: expensive, proprietary, vendor lock in to national instruments.
Also prefer text only rather than graphical click and drag programming.

For these reasons I'd choose python over labview in a hypothetical project where the hardware could be chosen to support either

Most people have been on a moderately high carb diet for most of their lifetime. It's gonna take a little more than 3-4 weeks to shift your perspective.
I've read a little about the "Dobkin Technique" where a cold compress is held over the eyes and face of a patient in cardiac arrest to simulate the 'mammalian diving reflex' and delay brain death like shown in these cases. Is there any truth to this or is it pseudoscience? Why wouldn't this be a more known treatment if it works?
No carbs is really hard if you exercise, or are an athlete. I stick to a low carb diet, but I can't imagine cycling/running 50+ miles a week in combination with weightlifting every other day, if I didn't have the energy from carbs. Chicken breasts and vegetables just aren't enough for me. (Carbs for me is usually oatmeal breakfast and protein bar)
Yeah well, it was a volatility spike.

> Services like these give Tor and related projects a bad name

In more ways than one.

What if this had been a tor website that was sharing documents proving government or police corruption? And yet somehow, the police did manage to shut it down. It goes to show that the tech needed for fully anonymous websites may not be good enough yet.

Any sufficiently anonymous website that could be used for good reasons can also be used for bad reasons. If Tor works, we have the good at the bad. If Tor doesn't work, we have neither.

If you read the linked paper (access is free), you will note that the authors are quite clear that they have a limited ability to determine causation. They say there seems to be some evidence that some of these risk factors are forward causes, but acknowledge it may be correlation based on another cause, or bicausal where the risk factor increases dementia which in turn reinforces the risk factor.

As usual, the popular news article goes straight to the causality argument because calls to action are more effective at getting people to read something.
