Cisco Tetration – The Death of Meaning
A review of Google searches shows Cisco's new IoP platform Tetration appears to be a big thing. But as a mathematician who has hosted http://tetration.org for twenty years and keeps tetration researchers socially organized, the continued appropriation of the word tetration is a surprise.
First it was Joshua Cohen's "Book of Numbers" where "Tetration" is the largest company in the world." Then a new company named "Tetration" began appearing in Google searches for "tetration". And then the references to tetration as a part of mathematics disappeared under the flood of results on "Cisco Tetration".
Big call out to the person at Google that provided disambiguation of the topic. Otherwise I've been unable to connect with anyone at Cisco Tetration. I'm disapointed that the meaning of "tetration" is being redefined from numbers that are incredibly large to meaning incredibly large amounts of bullshit.
Servo uses an existing JS interpreter (SpiderMonkey, the one used in Firefox) but does implement all of the Web APIs itself.
If someone on that forum says “should I try this IRL” and you say “theoretically, it should work fine” then, yes, you will probably be convicted. If you say “no, that’s illegal” and consistently do so any time you’re asked then you will probably not be convicted. If you say “that’s a great idea” you will be definitely be convicted. If you say “that’s a terrible idea ;)” you will probably be convicted while having angered the judge and jury for assuming they’re idiots.

I think it is generally agreed that the Dresden bombing had little strategic impact, so I would do a little more reading on the subject before you go claim that it was a necessity to stop the Nazis. Unless you think vindictively bombing a civilian population as revenge is justifiable.

Not necessarily - Australia has an expansion ongoing for the last 30 years.
I might, very rarely, do some maintenance of a BASIC program these days. And that would be because the program I am using might require some minor tweaking.

But invariably, I do all my new programming in C.

The flavor of BASIC I used to use is North Star Disk BASIC, very similar to HP BASIC.

So at its core it's just a set of access permissions + hiding of "forbidden" stuff? How about RAM and stuff, and hardware - does it get a true answer if querying its system? Or is that stuff virtualized too?

>US has the lowest unemployment rate in 30 years, wage growth, 3% gdp growth, and foreign direct investments going through the roof.

This really has nothing to do with whether a recession is around the corner or not. They don't just gradually come about over the course of years; they happen in an instant. Before anyone is even aware of what's happening the layoffs start piling up and it becomes exponential, as decreased business spending and consumer confidence feedback into each other. Fall of 2007 was the peak of irrational exuberance with a multi-decade low in unemployment and all time market highs, but by spring of '08 there was mass panic and people had lost everything.
The trick with waterproofing is that it's easy to do rainproof enclosures, but much harder to make fully submersible things.

For measuring water parameters I would be tempted to use a rugged box for the Pi and then cable (via a removable connector) to something you put in the water. Basically design a probe like the device you linked. The fewer parts that need to be fully waterproof the eaiser life gets.
> People value the convenience of Google's integrated services

So, short-term convenience should prevent us from breaking up a monopoly? The long term benefits of having a competitive market far outweigh the inconvenience of having to use tools from separate companies, or buy ad space from separate markets.

> Market fragmentation is unnatural in the software world

Oh yeah, that's why we have one text editor, one operating system, one browser, one CMS, one type of forum software, one chat app, one web framework, etc. Right? Having a fragmented market with tens, if not hundreds of competing solutions would be weird.
Harmless lonely teens who may be play-acting on 8chan are encouraged to become true believers by the rest who are sincere. The shooter involved in this case stated that he’d only been on 8chan for a year and a half and had learned much in that time. At some point the “fun” of it crosses a line for minds that have a strong enough foundation to leave it behind, those that stay become invested in the ethos. They embrace the allure of being the righteous underdog in a battle for the “future of white America”. Empathy and compassion are the enemy.
Well, I hate autoconf, so maybe poor choice of example. :P
I suspect that if you look hard enough at many areas that have a significant turnover in high value real estate transactions, you will find examples of international money laundering like this. NYC is widely believed to be a hotbed of this activity, and likely many other US cities are, also.
The functions/symbols being used were __kernel_fpu_{begin,end}. These were designed for use within the kernel, and not for external modules - however external modules used them since there was no other alternative. At some point the kernel announced these were being deprecated, and have now been removed.

Since they weren't designed for external modules, someone submitted a patch to make them exportable. However the patch enforced EXPORT_SYMBOL_GPL, so only modules that report being GPL licensed can use them.

Now ZFS is in a position where it can't use the original kernel symbols since they were removed, but can't use the new ones since they are marked as EXPORT_SYMBOL_GPL.

But per the other reply, containers are a lot less "contained" than VM's? I.e. if a program wants to list its set of processes, the host could fuck up and show them some from outside its container - whereas for the same thing to happen by a VM, it would have to have code to read that outside stuff, functionality it might not even contain... so vm's seem safer than containers... is that right?
I've been following the development of Servo for several years. Unfortunately it's still is at a very early stage. Some of the most basic sites are rendered incorrectly, not rendered at all, or result in freezes and crashes.

I remember reading about BTRFS parity patches that were shelved because they didn't align with someone's business interests. Maybe a storage vendor is exerting some pressure to impede modern file systems on Linux.
if they could orchestrate and get away with Khashoggi murder in another country

They totally didn't get away with it though. They were incompetent, bungled it and totally got caught. Faking an Iranian mine attack, including getting an Iranian navy vehicle filmed at the scene is orders of magnitude more complex and difficult. No way a gulf state could do it. US could do it, but couldn't keep the secret.
But the more innocuous, the less I care...
Back in the late 90's, I got into a USENET flame war, because the smallest, easily pruned ObjectStudio executable was an entire 4MB. Not small enough. Someone around that time got Squeak Smalltalk down to around 380KB. Not small enough. Back in the late 90's, you could still meet people who would insist that even your hyper-complex business app should be written entirely in C, because anything else was sinfully slow and wasteful. Any language with a VM was automatically too slow to be useful at all.
> I also don't understand how nice he is to North Korea in comparison to Iran. North Korea's government is probably the most brutal government on the planet right now and makes Iran almost look nice.

Because North Korea says nice things about him in public. He literally made it clear that all he wants with Iran is that he make a deal. He wants the photo ops, he wants the opportunity to look good. A not insignificant number of Trump's base already believe he "solved" the North Korea issue, and that's what he wants with Iran.

Personally I seriously doubt that Trump will initiate a full-on war with Iran. I said it in 2016 after the election and I'll say it now: Trump has a preternatural instinct for survival and spinning narratives, and wars are invariably lose-lose for everybody involved. He's not stupid enough to believe Iran could possibly turn out any better than Iraq. He may drop a few bombs to punish the IRGC for making him look bad, but then he'll find an opportune time to claim victory and move on or otherwise shift attention. Iran's regime is safe just like North Korea's is safe.

I'll credit npm with this, truly, when there's a package for each one of the Peano postulates. (As an actual functional dependency.)
I tested it last year on my static blog and it mostly worked, it missed some CSS like underline colours but good enough. I then tried wikipedia and just got a blank page.
Then what do you make of Iran showing up afterwards and forcing a ship that actually saved some sailors to hand over said sailors at gun point before the US could get there, therein making it seem like Iran rescued the sailors?

Or the photo of what looks like a mine, and the Iranian boat being in the exact same place...then that item just disappearing? Seems like a lot of coincidences.

That's even excluding a huge surge in activity of the Houthis, which are Iranian funded.

"It is also interesting that a 3rd world country's navy has better camera equipment than the premiere power."

I also don't know where you're getting this, the video the US Navy has is clearly taken from a drone miles and miles away from the ship, completely out of view of anyone.
I believe some operating systems have patches to get around this problem? See https://github.com/NixOS/nixpkgs/pull/61076 for example.
Visual thinkers? Is there some kind of categorization in how people think? Are there auditory thinkers, too?
This is exactly why we don't allow our employees to use Node.js for company software development, even though in theory a fair chunk of the runtime is our own software that we maintain. But the npm ecosystem has a really awful signal-to-dogturd ratio, and developers appear to put very little effort into critically analyzing their dependencies.

The topic has come up, but I'm generally against it; sure, we could spend all the resources on doing all the filtering and analysis and change management that it would take to establish a sane package base that we could officially support for internal development work... But why? We do it for other languages, but Node has a lot of "my first programming language" bs going on in the ecosystem. I strongly suspect that allowing Node development would be a net negative for our company.
>it's not even the top 10 predictors.

What’s your criteria for “top”? AFAIK every recession in the past century was preceded by a yield curve inversion. Also, what are the top 10 predictors?
the 2008 recession was characterized by 0% interest rate and bad mortgage loans. the 2000 recession was characterized by threats of emerging jobs offshoring and bad investments into internet companies that don't make money. the 1990 recession was characterized by threats of sky high oil price, and so was 1980.

Nothing like that exists to hurt US economy right now
I remember when I was contractor I had to get some screens from another building to kick off the project. They didn't have badges, just somebody at reception. I walked in, took screens almost $30000 worth, carted them out and left. This was my first day, nobody knew me, but nobody challenged me. Only afterwards I realized how crazy this was.

> discussing or (even better) trying to teach it to someone else is extremely effective.

Whenever I have to learn a new OS, system, tool, programming language, etc: if I have trouble with it, I just write up a training manual as if I were also tasked with teaching others. What I end up with is a customized courseware for just me that I can refer back to at any time. Time consuming, but very effective for me.
This is all old knowledge. I'm mystified why it's suddenly 'breaking news'.

That’s not what a black body is - that’s a body in thermal equilibrium

Wikipedia disagrees.

"A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. (It does not only absorb radiation, but can also emit radiation. The name "black body" is given because it absorbs radiation in all frequencies, not because it only absorbs.)"

We used to eat mussels off the beach all the time but now it seems like there’s a near continuous red tide that makes all shellfish toxic. I’m not sure if it’s pollution or just climate change.

I'll add my own story to the anecdata: my young daughter suffered from chronic constipation for years, nearly her whole life in fact. About two years ago I started her on magnesium supplementation, and within two days the constipation stopped. It has only returned once, on vacation when I had neglected to bring the magnesium with us.

The supplementation is simple and rudimentary. I add epsom salt to the tea that we drink as a family each morning. The dosage ends up at about 90 mg of elemental magnesium per day for her. From what I've read this is below the accepted therapeutic dose, but the I believe the cessation of her constipation is unlikely to be a coincidence.

Answer is simple practice for hours, days, months, years. Have the passion in you.

Personally the desire to express myself through music playing or writing songs drove me to finally get serious about learning/semi-mastering the piano/learn how to play by ear.

The guitar is a much easier instrument to pick up then piano.
This feels alien to me. As I play for fun of course I try new things, and keep expanding what I can do. That's how I've always learned music. I think I've even done my fastest growing while playing live for dances, which is probably the most "fun" and least "deliberate practice" there is!

You're speaking in very strong terms, as if we really understood how people become good musicans, but I think we really don't understand it and people take many different paths.

(My background: I started on guitar at about ten, switched to mandolin at about twenty, have always dabbled in other instruments, and at this point my main one is probably piano. I play in two contra dance bands, https://kingfisherband.com and https://freeraisins.com , and mostly play for dancing.)
That's what I mean by preternatural instinct. Yes, he's impulsive and a textbook narcissistic archetype. But that's not all he is. He's Donald Trump for a reason--someone who is successful almost despite himself. For decades everybody around him loses but he always worms his way out before the house of cards falls. However, avoiding the consequences is nearly impossible to do if he attempts to invade Iran, even if he had objectively good reason to.

At the very worst we may end up fighting a proxy war through Israel and Saudi Arabia and wrecking even more havoc in the ME, but there won't be another Iraq.

In that sense he's reliable and predictable. Russia knows this. China knows this. Iran, Saudia Arabia, and Israel, however... they may be cocky enough to try to manipulate Trump into doing things he simply won't do and is perhaps incapable of doing, and things will go sideways for them. For the U.S. our cost will be in treasure and reputation, which will be par for the course.

I would do your SQL like this:

select a, b
from t1
left outer join t2
on t2.t1_id = t1.id
where t2.c = 'foo'
and t2.d = 'bar';

- Lowercase

- I don't like that use of variable number of spaces to try to align things you did in both your examples. Doing that kind of thing in code generally leads to having to readjust that spacing whenever a new line is added or removed.

- Constant-width indentation indicates structure. "left outer join" is part of the "from" clause, so it's indented further. "on" is part of the "left outer join" clause, so it's indented further.

Among languages, I imagine SQL is the one with the most varied styling among those who use it.
