> It's like a forum full of carpenters that are using Black and Decker tools to build houses.

In that analogy the end result is the same, but the process to get there more complicated. In reality, the difference is between a house that has stuff like insulation and faucets that don't leak, versus than something slapped together in 5 minutes for $50 that costs 50 times more to live in, for as long as you live in it.

It's less effort for the programmer, more effort for every machine it gets run on, every time it gets run. And that stuff compounds in non-linear ways, too: The more data has to be read from disks, the more useless the disk cache becomes, the more data has to be shuffled around in RAM, the more useless the CPU cache becomes. Using gigantic frameworks for programs that use 0.1% of them, which still set up and maybe even poll for all sorts of stuff, not knowing it's not needed, is not "wrong" (certainly not ever when it's open source), but it's more wasteful for what it achieves.

I just checked, and my Directory Opus with 3 windows open, one of them having 2 panes, and all the custom buttons etc. is taking up 100 MB of memory. The list of features is huge. Another thing I have to think of is audio software. Sure, there's also VST that come with gigantic bitmaps or whatever, but generally, efficiency is king. They know their code doesn't run in a vacuum and they are dealing with customers (even when talking about free software) who pay keen attention to such things, to a degree unheard of and unstrived for here.

Sometimes I wish we could just completely freeze hardware development for 20 or more years (if it wasn't for improvements in energy efficiency) just to be forced to become better at programming again. Just look what in 2015 could be done with a machine from 1981: https://www.youtube.com/watch?v=hNRO7lno_DM ... What could we actually do with our current hardware? Who even knows?
You're original comment says you prefer government run insurance and give Medicare as an example, but neglect to note that 36% of Medicare is privately run.
I'd guesstimate flying on a 737 Max is still safer than driving a car.
I trust the bank because it has zero interest in subverting it’s own security. A government that doesn’t want to be removed from power has both motive and ability to do so. Paper Ballots allow Opposition Parties to count votes, an electronic voting system (wich would require the production of custom hardware in a government–owned facility to be remotely secure) would require the opposition to check for dopant-level chip defects.

Well, yes. Doing things that are good for the environment and our health is going to cost more money than not doing those things.

You do more than reference it -- you've copied a bunch of text and figures from it as well. Search for "The encoder’s inputs first flow through a self-attention layer" and read on from there. Most of the article is a word-for-word copy.
I think free will vs deterministic physics is a false dichotomy.

My instinct is that physics is performing a computation at optimal efficiency. Even if everything is deterministic, there is no other way to determine the outcome other than letting it play out.

In other words, even if a decision you made was bound to happen, there was no other way to find out what that decision would be beside letting you compute it.

So, your decisions can be both deterministic and unpredictable.

From this perspective, I don't think the existence or absence of randomness makes any difference on the question of free will.
We can't inform users how a particular breach affected a particular user (based on the fact of breach alone). Anything else is just FUD. It's like saying life in California is dangerous because there were deadly hurricanes there in the past that took lives.

We can't completely control hacker attacks. We should treat them more like software bugs or service outages. It just happens, we should focus on minimizing potential damage and proper response.
Every concern you mention is true for both sides of the market - seller and buyer. The buyer has spent a ton of capital on infrastructure and marketing, has loans and other bills to pay, and also has to provide service to their customers at good conditions - and timely - lest the customers go to their competitors. The buyer can't simply wait out indefinitely.

Unless there's a significant over-supply of the sellers. In which case the buyer can wait out any given seller, and get better deal from the next seller that comes around.

>If you know you have to work to keep your means of survival, you don't negotiate.

The very same concern goes for the buyers. They are just as well under the pressure of contractual deadlines and bills to pay.

I am sorry, but your post strikes me as example of "magical thinking" - "there must be something special about the owner-operated transport businesses". Yet nobody has provided any serious arguments towards that.

Just for the sake of contrast - you could imagine brain surgeons in the very same predicament. Suppose there were plenty of brain surgeons on the market - their prices (wages) would be very low, sometimes even below the costs incurred. No matter how pressed a patient would be for a life-saving operation, if there were multiple surgeons fiercely competing for this work, the price would be low.

The only reasons the brain surgeons are earning well is that the demand for service is higher than the supply - and there's little to no alternatives to a life-saving surgery.

You may balk at the example of highly skilled specialist surgeon, but it's true story of the eastern block [i.e., communist] countries, where supply of doctors was high, and the demand - which was only the state-funded healthcare - was fixed[1]. The surgeons earned rather low wages, and many supported themselves with bribes for access and expedited treatment.

Please don't tell us there's been "driver shortage for 10+ years". It's just fantasy.

--

[1] from the layman's POV "demand" for surgeries was high and nearly insatiable, but from the economics POV, demand with willingness to pay was fixed by the centralized healthcare planners.

The most interesting tidbit for me was:

The startup issue might be mostly solved these days with cheap lithium batteries and brushless dc motors. That said you still have the turbine issue and the fact that it'll be much much louder.
Do the companies that do this make any claims about how they benefit society? To me, stock traders in general seem a departure from the idea that money is a result of providing value to society, but arbitrageurs seem even further detached. I'd be interested to hear if there are arguments I haven't thought of.
Many thanks for your kind words. I have to confess, it was Jessica Lin who came up with the name "SAX". But I did run with it ;-)
There is evidence that nicotine alone is a complete carcinogen

I talked about average software dev. Google (payscale.com) says 64-66k, glassdoor says 70k. You do know that average also counts new grads right? Maybe next time try to actually comprehend the comment before using some adjectives.
I’ve no idea in practice in this case, but it’s certainly a common trope that organised crime sells expensive but safe waste disposal, then disposes of the waste cheaply and unsafely, and profits.
Albuquerque has awesome weather,* no
significant earthquakes, gorgeous scenery (tons of movies are shot around here), fantastic cultural diversity, a decent university, great food, plenty of housing and land to build on, and low taxes and CoL.

*Albuquerque is a mile high, so its climate is much more like Denver than like Phoenix.

What's not so great are a somewhat dysfunctional and corrupt state government, second-class health care and public schools, and a high-tech community that revolves almost entirely around defense work that requires a security clearance. Many of these would be remedied if Albuquerque somehow got a significant influx of startups.

I know the author well and he would likely conced to you some of the practical points you’re making about collocation and market microstructure. However he wrote the paper to illustrate how global compute networks could someday collaborate using the techniques described to facilitate AI. Hft is a early form of AI so if that’s an area of interest for you maybe take another look at that paper.

Unfortunately, the clientle isn't swimming in money. I play the double bass, and was visiting my repair shop. The luthier was showing me the instruments he was working on, and each story ended with: "Of course the customer doesn't have any money."

He has no competitors. Good instrument repair technicians are pretty rare. These guys could be making a lot more money repairing things like high-tech medical equipment.

One thing the Estonian system does is that you can verify your vote on a mobile device by scanning a qr code that you see when you cast the digital vote. A vote can be checked after i-voting for up to three times during half an hour.

I imagine if any mismatch was detected the country would shut off i-voting immediately.

This piece and its ilk are the real click bait of HN. Nothing new or interesting said here, just another “fail fast and early” piece that misses the bigger picture: namely, that unless you just want to make money—which is cool—failing fast and early is not what everyone is about. Finding a markov chain to a product is definitely a way to get there, if you just want to find some product, any product, that will sell to somebody somewhere. But okay, I’ve read this piece a hundred times. I get it. Please stop writing it, or at least please stop upvoting it.
> I would assume that they would do the same thing here, if this also turned out to be a widespread issue not related to aircraft maintenance or pilot training.

Two brand new 737 Max from two different types of airlines crashed in 6 months, what else you need to establish the fact that 737 Max worth to be grounded for a full investigation? How "widespread" it need to be? Maybe a few more crashes are required for FAA to make a move?

FAA's refusal to immediately ground all 737 Max is a pure political move to defend a faulty design that have already killed hundreds of people.
I was able to successfully quit cigarettes (for a year) by quitting drinking and switching to the vape. I reduced the nicotine from 12mg to 1.5mg over the course of three months

I did the same thing, and started again in the same way. I've just quit once again, and I'm determined to stay away from nicotine, and vaping for good now.
It's pretty easy to insult someone anonymously online. This is why I actually make a point of having my real identity connected to my HN (and reddit) account.

But let me just say this: after I built Lofi and got more hate than I would've imagined for what was really a throwaway project, a great dread came over me. What if I was new at programming? What if I was just a college or high school kid learning how to use Electron because I simply didn't know C++ or Java or what-have-you? I know that if I got this much hate in my teens or early 20s, it would've discouraged me tremendously from pursuing startups, programming, and building. I really hope you realize that your words can deeply affect people. I have thick skin, went to an elite school, wrote a book, I'm arrogant af, and couldn't give a damn about what you have to say, dear anonymous HN commenter....

...however, keep in mind that you might be negatively impacting an impressionable young person; or an underprivileged minority; or a total newbie. I hate the term "safe space" but we should all fight to keep HN as close to a Miltonian "marketplace of ideas" as possible.
My guess is that the raw tubes don't start out straight enough, so it takes the same amount of effort either way.
I find Austin uncomfortable in summer because of its humidity. Albuquerque is about the same temperature as Austin but because it's dry it's not uncomfortable.
FWIW, I've tried vaping, gums and nicotine pouches. They all make me sick, unless I drop the dose to a level that is so miniscule that I can't feel it. Real tobacco, on the other hand, calms me down and feels great as long as I watch the dose(say, 1/2 cigarette, but usually pipe tobacco). I don't use tobacco very often, and I've never had a problem quitting(23andme confirms I have low nicotine addiction risk). Curious if anyone else has noticed this with nicotine products? I know there is a difference in pure nicotine freebase vs salt form, but I feel like it's more than that. There's something else in tobacco that makes it work for me.
Maybe. I've PoC'ed it, but it's really rough. The biggest issue is UI. The indexer and query engine is primitive, but it works. I've been meaning to re-write it. If I do it after work I can opensource it.

I understand commerce makes the world go around, but why is anything and everything always measured in terms of profit and loss?

Analysis of Bitcoin: Cryptocurrency Experts Predicted Bitcoin Will Reach $36,000
Highly unlikely that 5g / iOS will play a role in the context of hft. Also your view of the ecosystem (eg zayo and co being the big winners) is massively outdated by five years at minimum.
Personal experience:

1. Smoked in college in earnest.

2. Started quitting after college with great difficulty.

3. Failed to quit for more than ~6 months at a go for a decade and half.

4. Started smoking e-cigs / vape last year (the liquid kind).

5. Quit vaping AND smoking months ago WITHOUT EVEN TRYING.

There was a pleasure loop hard-wired in my brain from smoking that I could ignore but would always win if 1) I was exceptionally stressed out or 2) I was drunk.

Without any difficulty whatsoever and without a conscious effort to do so, vaping somehow de-programmed that loop. My desire to smoke anything just disappeared. Stress and alcohol cause zero cravings now.

Further:

1. I don't recommend smoking. Risks far outweigh the benefits.

2. I don't recommend vaping unless you already smoke cigarettes and want to quit.

3. YMMV.
Yes! True said
Can vouch for Allen Carr's Easyway. At first the idea that someone can _talk_ me out of smoking seemed silly. Anyhow I tried it via audiobook that I listened while driving. Near the end of the book I just... stopped smoking. This seemed really weird to me. Allen has a weirdly effective way of explaining smoking away.
Fascinating, thanks for that link. I had never heard of the "anticholinergic cognitive burden scale".

Public Health England published a review of evidence of e-cigs. They concluded e-cigs are about 95% safer than tobacco. So being the same magnitude as cigarettes seems an absurd claim, on the strength of all studies so far, anecdotally too.

This is true that the latency of each operation won't change much as we increase concurrent accesses, but the amortized latency would (be expected to) reduce as the graphs show. When we did benchmarks, the Go benchmark framework provides us with ns/ops which we directly used to plot the graphs. We could calculate ops/sec too but that would just be another step of calculation using throughput = 1/(time taken/ops), may be more clear to understand though. The graphs would still flatten out after 20 concurrent accesses.

Well, if you have enough data you can predict anything. A dice roll is "random", unless you know the starting position of the die, mass, size, air currents, force of throw, on and on. With perfect data, you could predict the outcome. Thus, it isn't 'really' random.
(co-author here) The number of Go libraries tend to be just slightly below the number of their users (dramatically speaking).

Libraries are hardened by repeated usage by many different users who each bring their own special use cases and improve them to bring them to production quality. Go has no platform where certain well-written libraries can be recommended and get more exposure. Thus, they don't tend to mature more than the specific use case they get written for, provided they are still being maintained.

Arch Linux is a great example of giving well-doing packages more exposure by upgrading an AUR to community to core/extra. That way, more users gather around packages improving them even further.

To the second point about per-thread caching, Go does not expose threads to end-users. So, there's no concept of thread-local. What you're describing results in lock striping, which has contention issues as described in the post.
Out of curiosity, how does this compare with loose tobacco for rolling your own cigarettes in price and packaging?

I was in Australia on a trip last year, and met a lot of people who rolled their own because that was still affordable for them.
Aside from the homeless in Southern California a lot of young people are living out of vans. See Vanlife on Youtube, eventually these young couples living a Nomadic lifestyle will want to settle down and start families. Also, a lot of middle aged people are also living out of vans.
>> Note what is missing. No latitude. No longitude. No time source.

> That's wrong. Tracking which star zeniths is exactly latitude..

I think you missed the point. Latitude and longitude are Western concepts; concepts which the Polynesians did not actually use as such. However, they were navigators, so some of their navigational concepts and practices would obviously map to the concepts of other navigators due to a shared domain.

Similarly, they obviously had some concept of time. You could probably map their concepts onto hours and minutes, but if someone said they didn't have hours and minutes, they'd be right. The existence of the mapping doesn't invalidate that.

I might be missing something, but isn't opportunity cost a good argument for HFT?

HFT employs far fewer people than pre-HFT trading that came before it.

That's terrible advice. Champix and Zyban produce "feelings of agitation, depressed mood, hostility, changes in behaviour or impulsive or disturbing thoughts, such as ideas of self-harm or of harming others". I had several doctors literally tell me "to stay the fuck away from that garbage"
> The article implies that this is the Chinese government's way of signalling itself as a separate world aviation safety authority besides the FAA

Are you implying that before this "signalling" the FAA was a "world aviation safety authority" and furthermore the only one?
It befuddles me to see people relating this to external motivations, not a genuine concern for safety. Would you fly 737 max8 tomorrow? Anybody who knows anything about Chinese aviation industry knows that it is severely government-regulated industry and the top 1 priority is safety. It has better records than the American counterpart. While BOEING(being one of the pillars of American industry) might twist arms in corporate America, it simply doesn't have enough influence to warrant such risks with the Chinese government. Simple as that. I would very much appreciate FAA doing the same.

And it saddens me to see my comment being downvoted so rapidly. Has it become too hard in this corporate America to not buy into this bs? Has it not been obvious from history lessons that companies can only be held up to the moral standards that the law could effectively demand? A thorough investigation means potentially losing hundreds of billions of dollars. I would not expect Boeing to jump into this without some iron-fisted slaps. In the current trade circumstances, doubly not so. It is FAA's job to be doubtful and strict, not Boeing's. And it disappoints when FAA is testing reasonable doubts with human lives, not Boeing's profits.

If you are so inclined to downvote this, fly 737 max8 whenever you can probably help your corporate daddies more. Put your life on it where you mean it.
Would anyone kindly name a major company that install these mammoth cables underneath oceans?

In the personal development/emotional healing technique I've most used in the past few years, this concept is called "living in the future" and it's most certainly been a deeply ingrained tendency for myself and others I know, and is critical to overcome for one to make tangible progress in life.

A personal development coach I know trained me to stop talking to others about the successful things I plan to do or expect to do, the theory being that the subconscious/unconscious mind can't tell the difference between talking about them and actually accomplishing them.
