Seems like plug-in hybrids like the Chevrolet Volt could be really popular in the US.

Enough electric power to cover 90+% of daily scenarios, but an ICE that can be 'recharged' at a fuel pump in 60 seconds for long road trips.

You're obviously adding a lot of complexity to the car by having both systems, which is a drawback.
A neutrino is born in a weak eigen state (e,mu,tau) and propagates as a mass eigen state (m1,m2,m3). The two bases are related by a rotation matrix of three angles and three phases of which one, the CP violation phase, can in principle be measured with long baseline neutrino experiments. The oscillation happens because each mass state propagates at a different frequency. So while a numu starts out with some fraction of m1, m2 and m3 states, it soon becomes a different mixture which is neither nue, numu nor nutau. Instead, when the neutrino interacts, it does so with some admixture probability of doing so in the form of each possible flavor.
I don't honestly see a use case for this at all, I'm sure it solves some problem for you else you wouldn't have created it but it just seems slightly ridiculous.
It's so frustrating, because when it all boils down to it, the story is really quite simple:

1) What metrics reflect your customer experience? Monitor them, alarm on them. Target them as a priority for improvement. Check in on them weekly at a minimum.

2) What metrics make up the metrics that reflect the customer experience? Monitor them as well, and consider whether alarming on them is the right thing to do. Use these to direct what you target to solve 1.

3) What do you need for SPOF resilience? If you've got something critical, you need a minimum of two servers running it, and no more than, say, 40% total CPU usage so that you've got sufficient overhead to cope with a single host failure and any unexpected work increase.
This sounds vaguely like something I've heard in connection with Reid Hoffman and LinkedIn.

Not sure, but if there are a bunch of 40s years old, this would already start shifting the average upwards compared to the mean even if the data is rather centered in the mid 20s.
So, I guess the answer is - cash?

Either that or find something that people need and build it (rather than bitching about options/vesting crap).

Just a quick comment on this:

> Good software never stops evolving

I think I would translate this as: "our software is so large in scope, it must never stop evolving if it is to remain good enough."

Small software, with a single, focused goal, can evolve to a steady state which is still good.

Often we need to build things whose scope is too large for that, and must constantly churn. That's ok. But ideally you are finding parts of your work which can be sent in the opposite direction: towards God; or the oneness of all things.

If none of your work ever seems to find a path towards simplicity and oneness, it's possible you are pathologically mixing concerns, which, if true, is probably slowing you down.
I partly agree, but it doesn't sound like the Navy did their homework to check that the systems would even work.

From the article:

> It was also supposed to increase the lifespan of aircraft by putting less stress on their airframes. Unfortunately, recent tests of land-based prototypes showed that the system actually overstressed F-18 airframes during launch.

How do they just now discover that? Nobody thought to build a prototype on land first before agreeing to put it on a carrier?

It sounds like some defense contractors sold a bunch of neat ideas to the Navy and decided they'd work the kinks out as they came up.

The other problem is that there just aren't many companies that build aircraft carriers, and it's a very small market. According to Wikipedia there are only 37 aircraft carriers in the whole world, so nobody's going to do the R&D if they're not getting funded to do it.

I tend to just filter out phrases like that when I'm reading. I agree with your premise but as long as there's government funding involved, in any project that's guaranteed to get attention, someone is going to realize that it's advantageous to kill two birds with one stone by steering the positive press towards their party.

Hacker news used to be a site with optimistic people, entrepreneurs, people that did stuff, people that built stuff... now it's all whining about people that are actually doing things.

It makes me think of the roosevelt speech...

It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.

does anyone here have anything constructive to add?

I'm really inclined to say that Citus is better suited for the vast majority of companies, since You Are Not Google [1]. For example, forcing everyone to synchronously replicate using Raft all the time seems like overkill, and incurs a huge latency cost.

Furthermore, I think Citus has a head start on being a mature project, since it builds upon the back of the already-mature Postgres for things like query planning.

> I just would like more and more examples.

I'd like relevant examples. It's incredibly frustrating to look at an MDN snippet to see code that no sane human would ever write. Self-executing closures that return callbacks inside for-in loops, initialization code that still checks readyState, code that avoids more than one function for no obvious reason...MDN can be a real crap-shoot. Hell, I'd be happy if they would name their variables sensible things instead of trash like `numFoo`.
> The OpenSSL transition is keeping both versions around for a while, shunting the older version from package `openssl` to `openssl-1.0`, which will eventually go away too.

In my experience, this hasn't been a terribly unsettling transition and has gone quite smoothly except for a few individuals unlucky enough to update during a mirror turnover (or so I gathered from the forums as their problems often went away after updating again a short time later).

Mostly, insofar as OpenSSL 1.1.x is concerned vs. openssl-1.0, I've only had problems with projects that make heavy use of cmake as there's no easy workaround outside either a) creating/linking a few directories that cmake expects to find OpenSSL 1.0 in, or b) (my preferred approach because it avoids polluting the file system) patching the FindOpenSSL macro. But, I don't think this is a problem Arch needs to resolve as this is most certainly an upstream issue and only affects AUR packages (which, as you said, users of the AUR should already have some experience in this area anyway!).

You're absolutely spot on with that last statement--one of the reasons I love Arch is because package maintainers keep things as close to upstream as possible and GCC updates have largely been painless. Certainly more so than I recall under Gentoo.

Now that I think about it, the few pain points I've encountered with less frequently updated Arch installations have almost always involved multiple incompatible changes to core/filesystem layered with pacman updates. There are others, sure, but those ones seem to stick out in my mind the most. It's better to avoid them entirely by updating regularly, of course, but it happens.
About fucking time. I've literally been waiting for this for two and a half years!

This is absolutely huge.

It is indeed gambling. But it's an opportunity to buy a lottery ticket that has a much higher payout than one you could buy off the shelf. The odds may not be great, but if you happen to hit, the payoff can be very large.
The worst that can happen to General Atomics is that they don't get any new contracts after they're done building 3 (3!) fleet carriers. But building 3 carriers will give them enough expertise that they'll be able to bid on future shipbuilding contracts, and will probably land a few -- the Pentagon doesn't like letting contractors go out of business, and they'll recognize that General Atomics' giant Ford is at least half their own fault. It wasn't General Atomics that put out a contract for a fleet carrier that used every innovation at once...

Besides, I'm sure General Atomics had the sense to build factories in rustbucket towns and subcontract out to at least 26 states, preferably about half red and half blue; once your procurement system turns into a big enough jobs program, no one will dare to touch it.

Welcome to the cozy, comfortable world of defense contracting, dedicated to equipping the US to fight another world war, but only if the enemy is at least as cronyist as we are. The good news is that our only likely enemies for a world war actually are as cronyist as we are, or significantly worse -- but if any new Prussia ever rises in the world, we are _so_ dead.
Those features are fairly recent. In a high-volume cash business like fast food or a truck stop 20s will almost never get scrutiny unless the reflectivity or the feel of the paper are off. I used to process $8,000 to $12,000 an hour on a busy day, usually almost half of that in cash.

That's kinda vague philosophizing about an actual project. It seems pretentious and not constructive.

Do you have a concrete criticism of Citus? Do you believe a database system can become your definition of "God", or are large database systems simply not necessary and could be replaced by a few tiny God-like pieces? If so, why do large database systems exist at all?
SQL has actually been back in NoSQL for a few years now.

Spark SQL, Presto, Vora for example allow you to write ANSI SQL and query NoSQL stores such as Cassandra, HBase, MongoDB etc.

And if you are are after SQL-Like well then you have Phoenix, Hive, CQL etc.
Wouldn't that actually require the author to promote their own technology stack?
Good point. When voters are introduced to net neutrality the phrasing of the definition isn't going to be as clear as "Net neutrality is the principle that internet service providers providing consumer connection to the Internet should treat all data on the internet the same, not giving specific advantages or penalties in access by user, content, website, platform, or application." It seems more difficult to be against net neutrality when it's defined like this.

If people only get informed about the net neutrality issue from TV advertisements made by ISPs then the results will be a lot different.
Fascinating to see where these folks ended up nearly two decades later.

I guess you may be right! I presumed WebAssembly to be some sort of opaque "goto-soup" (unlike minification), as the term "assembly" suggests.

But I looked it up and it seems WebAssembly preserves the structure of the original document, just like minification, at least that's what I understand from the following quote:

"In practice, outer blocks can be used to place labels for any given branching pattern, except that the nesting restriction makes it impossible to branch into the middle of a loop from outside the loop. This limitation ensures by construction that all control flow graphs are well-structured as in high-level languages like Java, JavaScript and Go."

USS Ford

It reminds me of Qing China in the 1890's.

"On paper, the Beiyang Fleet had the superior ships,[2] included two pre-dreadnought battleships, Dingyuan and Zhenyuan, for which the Japanese had no counterparts. "....."Though well drilled, the Chinese had not engaged in sufficient gunnery practice beforehand. This lack of training was the direct result of a serious lack of ammunition. Corruption seems to have played a major role; many Chinese shells appear to have been filled with cement or porcelain, or were the wrong caliber and could not be fired."

https://en.wikipedia.org/wiki/Battle_of_the_Yalu_River_(1894...

"Li wanted to delay the battle against the Japanese fleet, thus allowing the Chinese more time to equip their ships with additional ammunition. However, the imperial court called him a coward and his recommendation was turned down."

"Defense spending analyst Winslow Wheeler concluded from flight evaluation reports that the F-35A "is flawed beyond redemption";[196] in response, program manager Bogdan suggested that pilots worried about being shot down should fly cargo aircraft instead."https://en.wikipedia.org/wiki/Lockheed_Martin_F-35_Lightning...

I don't think U.S. is at the terminal stage yet, as Qing China was at that time - but it certainly rhymes.

> The military is always in a bind with contractor selection. If the don't choose the lowest bidder they get hauled up in front of a Senate committee full of people grandstanding for the next election accusing them of taking care of cronies.

No, they (or, rather, contractors) solved that problem by assuring that all contracts are divied up between as many states and Congressional districts as possible, so that anyone in Congress attacking any procurement is attacking jobs in their own district, and cost controls are less important because the overruns are also producing work, often also widely distributed.

Of course, this also produces the problem (for the military, not contractors) that any attempt to impose accountability on contractors has political problems that are similarly widespread.

Isn't that kind of thing a real red flag for the kind of talent you'd want to attract? If someone told me they'd built a GPU compute cluster for their phpbb based social club forum, I'd think they were an idiot and not want to work with them.
Yes, exactly. The start-up I joined did this with a fair vesting schedule. Now I own actual stock in the company without having to pay any cash to take ownership of them. One issue we've found, though, is that early employees have less of a reason to stay on once they become vested. With options, as long as they're employed by the company they don't have to exercise. If they leave, they have only a short period of time before they have to come up with the cash to buy their shares.

One other downside is that an LLC can't go public, so if the company decides to go that route they'll have to reorganize to a C-corp. Of course the lawyers love this because the paperwork required is significant.
Not disagreeing with you, but something about large corporations buying government officials to enact their preferred legislation doesn't sit right with me.
My experience has largely been the same, the whole mono, xamarin, vs studio, etc of tooling (whatever it all is) is a tragedy of good technology made useless. The licensing, tooling, and runtimes are such a mess I give up before I begin. There needs to be one canonical way to do things on every platform, this "band-aid" approach might've worked when you first open sourced but surely no longer does the job.

I'd love to use .NET but the overhead of getting started isn't worth it when I can use any number of other truly free languages/platforms that are much easier to understand. And are truly cross platform because they have been so for years.

For reference languages I use regularly or on occasion which don't suffer from any degree of the issues .NET has: ruby, swift, elixir, java, scala, JavaScript, and Elm.

CLR and .NET seem very awesome but so far have turned me off in a big way. Please fix <3

I seriously doubt you need to spend more than 100% the cost of the 8 GPUs on the rest of the system.

If your 8 GPUs cost ~6k USD, you should be able to build a system for under ~10k USD (even ~8k). Any extra money you spend is more out of desire to "max out" your specs and less of a performance boost.
Yes because ordinary users never, ever opt in to things they shouldn't. And because of that one opt-in mistake suddenly they have invisible service workers mining Bitcoins which they could never learn about since the discovery mechanism for service workers is currently non-existent.

Again, the concept of background tasks isn't necessarily a bad thing. But it needs to be locked down to specific use cases not a free for all allowing arbitrary JS to be executed.
Yeah, that's some nonsense. Full-stack (your team manager's "cross-functional") today is mostly a delusion. Sure, you should be able to read some code on both sides to tackle the trivial parts of either, but I wouldn't expect every developer to have semantic understanding nor constant involvement on both sides.

Sorry for your recent misfortune and I hope you find a more reasonable next gig (cough next manager cough).
