American cars currently have good quality. There was a substantial period of time in which they didn't. That time period is what GP referred to. US automakers are still playing catch-up in terms of brand image and reliability engineering (as practiced by Toyota, through which quality improvements flow for decades), which persist for decades.
I presume whatever Musk said was referring to something legitimate, but to put a finer point on your comment: in normal jet engines, only a fraction of air actually goes into the combustion chamber. The rest is just pushed out the back (faster than it came in) by turbine blades that are driven by that combustion. Indeed, modern jet engines are "high by-pass" which I think means that the large majority (>80%) of air isn't part of the combustion.
Are you using evil mode? It seems to be suggested by the spacemacs docs.
I have worked in the United States for 10 years on a non-immigrant visa (I have no other way to work in the United states and 7 years of H1-B lottery have yielded nothing). I have paid more than six figures in taxes to the Feds, as well as contributed to an American business and being an active community member. I have no path or way to immigrate to the United States nor can I use by past decade of contributions in any way. Its a slap in the face when I read about people literally buying there way in and corrupt politicians and businessman manipulating the system without consequence.
> People with this same thinking got in 6 months ago and have lost more than 50% of their savings.

Well, nobody guarantees growth, especially short term.

But 50% loss after a 1000% growth is still better for many people experiencing hyperinflation. Bolivar lost more than 90% of its value in the last 6 months [1].

And hey, if you prefer dollars or euros, all the power to you, use them. But I won't, cause I know it's designed to lose value.

The real lesson is that your DNA was never a secret at all. Almost the entirety of it is shared with many people (your family) and you literally leave it everywhere you go. Don't assume any of it will be kept hidden.

Wait, you cited my text and changed it from the original dropping a key word and then attacked me for it. Not cool. There is no feigned surprise or lack of respect either implied or actually present in my inquiry about the lack of tests.
Air-breathing ion thrusters for aircraft are not at all practical yet. The first demonstration flight of a self-contained unmanned non-payload-carrying aircraft using one took place last year.

The per-unit energy is the biggest issue. It's true that fire is a problem for batteries, but that is manageable with very small sensors and casings.

There are many more systems required to deal with the many failure modes of internal combustion engines:

- Heating systems to address carburetor icing. Typically manually activated by pilot since they have a performance cost.
- Fuel pumps since gravity cannot always be depended upon especially in acrobatic airplanes.
- Fuel sump systems which must be checked before every flight to address water in the fuel tanks & lines.
- Lubrication systems which require pre-flight fluid level checks.
- Magneto system to ensure that sparks can be generated independently from the electrical system.
- Redundant magneto system since carbon tends to build up and prevent proper sparking.
- Possibility of an engine running rough/cylinder firing out of sync due to carbon or other issues.
- Fuel/air mixture control so that the optimal mix can be selected based on altitude. Requires pilot intervention.
- Extreme thermal stresses on the engine, requiring engine run-up checks before takeoff.
- Radiators, and airflow rediretion to address cooling issues resulting in loss of performance and weight.
- Exhaust system, and noise vs. weight tradeoff
> I want the super-fast, high-flying, supersonic electric planes please!

Me too, but it's pretty chilly at >35,000 feet up, where most commercial jets fly. Batteries really don't like the cold.
Sure you can. Encase them it metal, and use the remaining batteries to power a railgun...

This is the full quote:

“The researchers note that while they believe these results are causal, more research is needed to prove direct links between specific exercises and mental health. Still, they feel comfortable stating the difference between working out and not working out is the same as ‘between individuals with a difference in household income of more than U.S. $25,000.’”

I am not sure how they arrive at that number especially when they haven’t even proven a direct link.
There have been a few different projects for tracking issues as objects in Git storage, but they all do things in slightly different (incompatible) ways and none have gained enough mindshare to be commonly used. My guess is that none will ever gain enough mindshare without being packaged in with git itself, either, so we got ourselves a chicken and egg problem.

Thanks so much for pointing these out :) Yes, as we speak, I am working on updating the README, supporting docs, and a better website for the language/project. I will let you know once I have these up and running! It would be great to get your feedback.

You have to rethink the work you do or you will stay in the same traps.

Here's what I learned doing a PhD. If you have an obsessive interest in something and put in an effort into something you can make "something that I've never seen before" that makes a good demo in a few months.

Larger firms are more stable than small firms, possibly more likely to offer health insurance and other benefits. However there are smaller firms that are better to work with than some others.

Work on interview prep should be as much about social skills as technical. I used to joke that you could pass any data science question with "look it up in the hash table" or "look it up in the literature". I failed to define the word "Regularization" in an interview with a team and I did not fail the interview because I was too busy regularizing things. Showing enthusiasm is good.

I can only imagine that this would just make the photos unusable (I imagine a "John Smith" printed diagonally on a photo, enough to make it 'viewable' by friends, but unusable by advertisers. Of course there is always photoshop, and I will assume that even if someone watermarks a photo like that, someone, somewhere can spend 10mins and process/edit the semi-transparent letters so as to 'remove' them from the picture.

It isn't even open source and appears to have very little active development. Very poor quality overall. No one would switch away for something like this.
Nope. But in some jurisdictions consumer protection and data privacy laws ought to prevent FB doing this, their EULA notwithstanding.

However, bear in mind that this is from The Telegraph, which is a not a high quality news source. There is likely to be a significant element of misreporting, so I'd like to see a verifying story from a credible source before damning FB.
Comparing a new 172 to a new eFlyer the price seems competitive ($300k vs. $350k it looks like?)
> losing all systems plus the motor at the same time would seriously jeopardize the safety of this aircraft

The 2-seater is VFR only, assuming with conventional mechanical control surface linkages. So if you lose thrust, you're basically a glider at that point, needing only backup steam airspeed and altitude, and maybe a yaw string, to land safely. The electronics don't buy you much at that point.
Isn't this how real-world warfare is trending already? A vehicle full of soldiers may die before they even know there was a threat flying overhead. But it's not very heroic-looking to just keep the laser designator on target until the bomb lands.

I suppose that's why so many contemporary thrillers or even far-future science fiction movies devolve into hand to hand combat for the climactic showdown. It looks more interesting. (Though personally it makes me groan and want to throw things at the screen.)
I don't have any experience with either of these, but for later stage, these are well known:

It's worth noting that 'paper' is from Lydon Larouche's 'Executive Intelligence Review'. Not what I would consider a reliable source even in 1986 the same year he was arrested for credit card fraud. He was subsequently convicted in 1988.

As to the content a gamma ray laser is a fun idea but if there were any of them in "as little as three years" and if they had applications then those have remained secret for quite some time. Every public indication is that there aren't any. See here for a discussion: https://en.wikipedia.org/wiki/Gamma-ray_laser
Sure, and if any of those cities all the sudden decided to no longer produce domestic product, that would be a big risk to the US.
What I'm interested in out of this information (but not interested enough to look it up myself): These five cities account for 1/4 of their business, but how does the population of these five cities compare to all of the cities they do business in? Is this just a straight-line distribution?

Basically, do these five cities account for 1/4 of the total population of the cities they do business in?
400 hours/minute is 24,000 minutes of video per minute, or 241,920,000 minutes of video per week. Assuming a human can review 8 hours of video per day, 5 days a week (too high, but not by much), and that YouTube engineers can create an algorithm that automatically marks 95% of video (probably low, 95% correct labelling is easy to get; 99% is usually necessary to outdo humans), then you would need 5,040 humans.

Automatically labelling 97.5% would halve that. If employees can only review 6 hours of video per work-day, then it would increase by a third. Both, you'd need 3,360 humans.

The problem is that this kind of studies should be discussed only inside medical centers where the next more reliable studies are designed. The discussion with general public degenerates because most people don't understand the difference between a preliminary study and a good clinical study. You will see in a few days a press article in a major newspaper with the title

Is the multi threaded implementation, being talked about for some time part of this release? Sometimes the single threaded nature of emacs causes problems while running complex setups like cider, nrepl etc.
The last line in the article answers that pretty well:

This is the kind of stuff they say like 9 months before a major downturn.
There is no "true worth" that you can look up on a website. Your salary is your cost in the labor market. And like any market, worth is determined by what people are willing to pay. Go out and interview, get some offer sand see who is willing to compete for you. That's how you get your true worth.

Smaller motors unfortunately means smaller propellers which means smaller swept area and a large decrease in available power.
I have, I like the product and I agree about the user-friendliness, but it doesn't quite do it for me.

Actually, I should phrase it a different way. For me, Notion competes with OneNote, and for my personal use they're somewhat comparable. Notion doesn't take the spot of Excel/Sheets in my toolkit because Excel/Sheets can be gradually automated out of initially fuzzy requirements.
I'm in the exact same boat. Every few months I spend some time learning Emacs. I'll hit a road block and go back to VSCode or PyCharm. Then I'll feel silly b/c I'm already super productive in those and just wasted time, but want Emacs to work. Few months later... repeat! Why emacs!?!?
> The whole point of currency is short-term

Not if you're saving for retirement or your kid's college fund.

We never had any deflationary currencies till recently. Now we have a choice.

If you want to quickly spend your money, go right ahead, nobody is stopping you.

I prefer to spend for what I need, and save the rest, and it's been working great so far. That's what most financial advisers advise anyway - live within your means, and create a financial cushion.
This data seems to affirm some factors I identified in another thread about what research to do on a company before joining and what questions to ask them.

My view is that incentives drive strategy, which then drives culture. Again, all IMO, but the later stage a company is, as an employee the greater portion of your energy will be devoted to sustaining cognitive dissonance to survive, as a priority over applying creativity and technical skill.

According to the data as presented, by the time the company has hit the C and D rounds, the founders have lost control of the company. Culturally, it means the visionary stage could be over, and founders may have a company wide technical veto, but with no way to drive their own initiatives.

The culture could be defined by a power struggle between the new(ish) CEO's team and the founders' tribe. Find out which tribe you are supposed to be joining before signing on and act accordingly.

As a developer, after C and D, you will more likely be solving optimization problems and all the tech debt they accrued to raise the previous rounds.

The exception will be if they raised the last round to finance a big pivot, where you can build something new again. Joining a pivot team is great, but there will be an attrition period as the old guard is cleared out.

It's tea leaves, but potentially useful questions to ask if you are about to invest 3-5 years of your life and your reputation into a company.
Voat isn't just what you get with no censorship. It's what you get when you're a new alternative to a large incumbent: you are populated almost 100% by people banned by the incumbent. Nobody else has a reason to join your platform. It's a phenomenon that makes it even harder to compete with an incumbent social network.
It costs NYC about 2.6 billion to construct a mile of subway.

In light of that, the money invested in self-driving cars is pretty small.

There are people who paid 10-15 years into SS and Fed taxes (sometimes more than 500K) yet have a long, long way to a Green card or citizenship.
VFR is the most dangerous situation to lose all systems in your aircraft. You're low to the ground, and relatively slow... and may or may-not have radar following or even be near a controlled airport. You'll have a pretty short maximum glide distance, and won't be able to communicate your emergency nor intentions.

Engine-out's happen in GA, sure, but a total loss is pretty rare. Bye and his company will have to prove beyond doubt his design is at least as good as existing decade's old, super-proven designs.
Congratulations and a huge thank you to all those involved! Emacs is a truly remarkable piece of software. I started using it for text editing over 20 years ago, now I use it pretty much as an operating system!
I have had an amazon card for a few years now.

I can't say anything bad or good about it. I get 1% back (or points to spend at amazon) for any purchases, 2% points back for gas, and 3% points when I use it at amazon.

There's been more than several times where it looked like it never applied the points to my account though. I always paid it off in full every month, and sometimes it works sometimes not. When I lived on the road and used it for hotels, while getting reimbursed from them, I was able to rack up $1500 worth of points.

Other than that, it's been fine. Looking around for something a bit better though.

> The reality of the 6-pager in 2019 is that it has become boilerplate where style overwhelms substance.

I can't say I agree. I'm in the middle of a 6-pager, and the overwhelming majority of feedback/comments from people I've asked to review it have been very specific to making sure there IS substance. Tons of 'This is unclear. Need extra details and specifics', 'Why is this the case?', and so on. Plenty of grammar/style feedback as well, but the whole point is attention to detail.

io_uring dumps data directly into a ring buffer mapped into the user-level address space. User code is notified by (at least) an updated atomic counter. The user process must be finished with the data before the kernel comes around again to overwrite it. Often that demands the user process or thread is bound to a core which the OS has been forbidden to run anything else on, and the thread does a carefully circumscribed amount of work, rarely including memory allocation, i/o, or even system calls, that may cause it to be "lapped" by subsequent writes.

The idea is that the average time to process a packet absolutely must not exceed the average arrival rate, and the sum of spikes in arrival rate must average out over the size of the ring buffer to less than the process rate.

The hamster process pulling from the ring may just be load balancing to a herd of other threads operating under less stringent conditions, so they might be permitted i/o.

When you catch yourself doing things out of FOMO, take your dispositions and fix it. In this case: close the app, or configure the alerts.

I'm sometimes alarmed by how people seem to have zero self-knowledge and appear to run on auto-pilot, guided by base impulses.

The issue will always be that fuel is consumed and causes the aircraft to be lighter the longer you fly.
Wait, what? A minimally invasive _craniotomy_? Cutting open the skull generally isn't thought to be minimally invasive. Cool technique but a rather crazy title given that the paper barely touches on invasiveness. Much better would be "biocompatible" or "mechanically stable" or "long-lasting."
Also, SpaceX’s landings are amazing, but looking at the numbers (https://en.wikipedia.org/wiki/List_of_Falcon_9_and_Falcon_He...): ”The rocket's first-stage boosters have been recovered in 35 of 42 landing attempts (83%).”

If Tesla’s cars were as good in parking as that, one in six attempts to park a car would lead to a fender-bender or worse.

Yes, that isn’t a valid comparison, but it does show that we accept way higher failure rates for rockets than we do for cars (aside: that also is the reason I don’t see space tourism become popular soon. If, say, the 20th or 30th millionaire who books a flight dies, the market will dry up rapidly)
Not as much as I did, LOL.
