zsh does (has an option to) commit commands to the history file immediately when you execute the command. Makes me hate bash even more when I have to use it occasionally on a server.
Is it just me or do none of these voice products seem like they are ready for the consumer? I have never seen one work properly on a consistent basis.
You're talking about Arnoldi Iteration. It's useful in a few cases, but it doesn't scale as well due to the fact the component matrices are no longer sparse.
I’ve flown just about every commercial model of airplane made in the last 30 years including Emirates A380 biz class. While that was undoubtedly an amazing trip, it had a lot more to do with the airline than the airplane. My enthusiasm for the trip also dropped off when I had to spend several hours waiting around in the middle of the night at their hub in Dubai.
CCC is so heavily oversubscribed that there is an insane race every year when tickets are released, usually involving downtime for the ticketing app. If finding the app itself already presents too much effort for you (hint: https://www.google.co.uk/search?q=ccc%20tickets ), it's unlikely you'll succeed in acquiring a ticket.

Your best bet is to source one through some affiliated group, if you know of one, otherwise spend a few hours familiarizing yourself with the ticket app, and have at least 2 browsers with at least 10 tabs each open on the app ready for the second a release happens
It IS shitty marketing, I do agree. You might be interested in their Wiki:

Given that they manage to attract thousands of hackers anyway, I guess it's just not their priority to make this clear.
Refactors and merging projects of Angular 4 into Angular 1.5
Boeing most likely has already delivered the last passenger 747 ever to be built [1]. Cargo demand will keep the line alive, but at greatly reduced numbers, which in total have been 1536 units since it's commercial introduction in 1970 [2].

IMHO, the A380 was not created to meet market demand, but instead was conceived to meet the national interests of England and France's own military industrial complex, and in that regard it was a success.

edit: format fix.
Yes, it would be nice if reflowing became more common. We are not sure if our spec requires the terminal to support reflowing (because of the resource usage implications), but the terminal must at least be able to announce whether it does reflowing (and/or word wrapping).
Yes! See my other comment - the DXB stopover is their Achilles heel I think.
I hate that plane, I flew it from Melbourne to LAX and won't do it again. Weirdly noisy and almost hits the end of the runway on takeoff. No thanks.

I like that they're easy to automate actions with.

I hate that commands are difficult to discover.
But the segment has an outsized impact on revenue.

Say a business class ticket for a transatlantic flight is 5x an economy and a first class ticket is 10x an economy.

And the plane, of course, is largely fixed costs.
I thought this was a pretty useful project for embedded work, and despite it being a few years old I'd never heard of it.

The documentation is a bit... eclectic.

Tup is a build system that keeps track of what files a command accesses. So if you run make from tup, it can look at every file your makefile reads from, and re-run make if any of those files change. Not that useful, in that example, but when you have it run gcc to make each source file instead, it can automatically rebuild just the files that need to be rebuilt.

Building on top of that, they've set up a git repo with the appropriate "tupfiles" (makefiles) to build linux and enough userspace to get by. It's not so much a linux distribution as a build-system that can build an entire linux distro from source.

The big difference between this and a normal build system is that all your source files can be in the same tree as git submodules, and `tup upd` will rebuild the entire thing, only recompiling code who's source file or shared libraries have changed.

I think it could be a pretty powerful system for a lot of projects, I'm particularly interested in using it for building android images, and firmware for ereaders.

Bombardier is not a part of Airbus now, they just sold 50.01% of the C-series program to Airbus so that they could manufacture them in Alabama and dodge the 300% tariff imposed on them by the US government.

I cannot upvote you enough, it's true.

A380 is in its own league, super comfortable, super low noise. No 747, 777 or 787 can match the comfort. They are noisier, or have downsides.
We are currently doing most of the work offline, so it's difficult to collaborate with a far-reaching network of contributors at this point.

It's a dangerous illusion of modernity that you can just pick up a "high quality" newspaper or watch the news and understand what is happening in the world. Or even in your own region.

One possible advantage of the total chaos of internet news is that the noise becomes so strong that we can't even receive the signal of traditional news sources with their "expert opinion" anymore.
It's philosophically related. Very much related and of much more interest these days. Specially since transgender people have such high risk of mental illness and suicide, they and close ones need to be made aware and informed about theoretical issues regarding their beliefs. If they are served only the one-sided ideological views so not to hurt them emotionally, they are not really protected, but only encouraged to risk their lives in the hope the world will change by force and not by argument and debate.
So, it took almost 100 years until the mainstream understood what should have been blatantly obvious to anyone who thinks about it: Oh right. Oil is limited.

I mean, sure, if we search long and hard enough we will probably almost always be able to find/produce something, but I don't think asking 1 million per liter of gas would be such a great idea.

Hoping that there will always be a scientific breakthrough just "right in time" to solve our resource problems is great. I love optimism. It's also extremely irresponsible to depend on it.

Sodium is not fundamentally better material than lithium, though. It's just a bit more abundant (but lithium is very abundant and can be extracted from actual ocean water, though because of lithium's abundance, that will never be the cheapest way to get lithium).

Lithium is the third lightest element and the lightest (regular) metal. Sodium is much heavier.
The thing is, you can't fly big planes between small destinations because they will be half empty. Years ago planes weren't efficient enough to allow small planes to fly the long distances that are flown today. So, point to point is possible because planes are more efficient
One example: A common ml algorithm called principal component analysis makes use of the eigenvectors and eigenvalues of a data set's correlation matrix. The dominant eigenvectors can be used as a basis for data compression and the size of their eigenvalues determines the accuracy of the compression.
Yeah, if they're already oversubscribed it makes sense that bringing more people in would have zero benefit for them (unless they wanted to raise the price). Thanks for the link!
Vietnam is a fairly large country (90 million people) that has a lot of potential. They are also next in line for decelopkent, and China antagonizes them enough to put them in the USA’s sphere of influence. Besides, China isn’t interesting in importing the goods Vietnam manufactures.
You mean "oil cautionism" based on the very well established fact that reserves are limited (and it took the billions of years to be created)?
And the US has 10x the population density of Canada. Yet we manage it somehow (except for internet). I love how the US is simultaneously the most powerful economy in the world and completely hapless at putting any of that to use for the good of its citizens.

For a self-writing timed exam essay, structure more simply:

- Thing because reasons 1, 2, and 3.

- Thing because Reason 1. Reason 1 elaborated. Supporting examples.

- Thing because Reason 2. Reason 2 elaborated. Supporting examples.

- Thing because Reason 3. Reason 3 elaborated. Supporting examples.

- From reasons 1, 2, and 3, the thing.

Paint by these numbers against the clock:

- Divide time available by 5, e.g., 50 minute period, 5 intervals of 10 minutes.

- Tell 'em what you're going to tell 'em: Spend first 10 minutes thinking about the topic and write a thesis statement based on three persuasive reasons you can support with examples from what you remember about the topic. (10 mins)

- Tell 'em (x3): Spend each of the next 10 minute blocks writing a paragraph connecting that part, elaborating on the reason, then providing as many supporting examples as you can fit in the ten minutes. (3 x 10 mins)

- Tell 'em what you told 'em: Write a compelling conclusion based on the reasons. Spend any leftover time proof-reading. (10 mins)
Yes, lithium can be and is recycled.

But mining is even cheaper because lithium is actually abundant.
There are lots of perfectly usable, productive, and profitable applications written in cobol, still chugging along, making, in some cases, $millions for their owners. Often these are government organizations or large enterprises who have no incentive to change, and lots of reasons not too.

One of the biggest reasons to stick with legacy cobol applications is that, often times, these applications grew organically over decades to encompass business process for entire industries. There was never one single design document or even goal. And hence the functionality of the systems are poorly documented and only really understood by the cadre of users who use it from day to day. Ie they are incredibly expensive or even impossible to replace.

Another point that's never made in discussions about cobol is how incredibly "safe" it is, from a security perspective. Cobol is a lot like (an incredibly verbose) assembler, all storage is statically allocated before the program even starts. In cobol there in no runtime stack, and no dynamic memory allocation. So no chance of buffer overflow attacks or trashing the stack.

Yes. Tesla's standardization on one or two cell types allows them to build specialized machines that can efficiently and quickly disassemble and recycle the components of the cell.

> the question hinges on whether they need a frame of reference for those feelings

Why not? Just about every other medical treatment require far greater standards of evidence than just a subjective feeling. For example there seems to be wide consensus in medicine that those with body dysmorphic disorder are to be denied amputation of healthy limbs.

> Perhaps it is like the feeling that you're hungry

To which the equivalent conditions would be the various eating disorders, where medical efforts seem to be focused on restoring normal eating patterns rather than reinforcing feelings of being either too hungry or not hungry enough.

And unless there is a disorder like this, it's easy enough to gain a frame of reference, we all know what it's like to be hungry vs. not hungry.
Smartphones stopped being status symbols years ago and the development of phones has stagnated. I could not tell the difference between my old and my current phone apart from battery life.

Looking back 10 years doesn't make sense because development was rapid then. But look back 5 years and there isn't a huge difference. A phone from 5 years ago would be fine in 5 more years.

Software updates and hardware serviceability are the bottle necks in phone longevity. The challenge is economical, cultural and political, not technical.
I think coverage of the A380 often misses the point that at the time, Boeing's 747 simply had no competition, whereas all of Airbus's planes did. So Airbus pretty much had to create the A380 in order to protect its other lines from cross-subsidy by this unopposed cash-cow.

And, also missing from almost all the coverage is the fact that this worked: if the A380 is struggling, the 747 is moribund or dead. Official backlog for the A380 is ~100 planes (actual may be less), the 747's is 21. "the 747 line could be closed in the third quarter of 2019".

And I don't quite get how Boeing somehow played this better, it's not exactly that they decided not to develop a jumbo, they just already had one, whereas Airbus had a bunch of mid-size twins (in fact, the company created and was founded on the mid-size wide-body twin, the A300).

Now you can argue that both planes "were"/might be killed by the shift to smaller twins (and the shift in regulations allowing much longer ocean crossings with just two engines, heck, I recently read that they are now doing the Atlantic in 737s!), but I don't think this is necessarily so, at least not by itself.

Boeing might have been right that there wasn't space in the market for two such planes, but that's a comfortable position if you have the monopoly in this, the high-end segment of the market.

I also am not convinced that the reason given for the A380, constrained slots at major airports serving the major routes, is entirely invalid. With air travel growing the way it does, this problem is not going away, and the shift to more point to point routes may only have been a temporary reprieve.

As an example, Lufthansa recently used jumbo jets on the domestic Frankfurt / Berlin route after their competitor Air Berlin went belly up.
You're trying to justify it in the sense that they're some sort of smart people with a plan. They're just civilians, they're not spies. No malice or cunning elements to it - just idiocy.

The takeaway I got is that they just don't want people to visit Israel and made it as difficult as possible for me (which involved taking away my personal documentation, such as my invitation letter and copies of my citizenship, to give me a tough time when I got to Ben Gurion).
Because leaving it plugged in means continuous power, therefore you never have to remember to charge it.
Um, there’s 5 787s flying around for every A350. On the future book Boeing also has around 50% more 787 orders than Airbus has A350.

So yeah, I’d call that being a bit behind in that market segment.
Driverless cars became a reality in 2017 and hardly anyone noticed
This makes sense about the stopover, but is why these airlines have gained a lot of traction with travelers from the Americas to Asia. Particularly from the eastern part of the Americas to non-eastern Asia, an approximately 10-15h flight followed by a 0-8h is relatively nice for getting sleep. However, I am definitely not a fan of the DXB terminal that Emirates flies into with its dim lighting and incredibly high number of very expensive shops. A high-end mall is not what I am looking for after hours of sitting on a plane.
TL;dr version - (pending) Patents = value. Ergo, these ICOs are valuable.

This obviously is a terrible idea. Pending patents (2/3 mentioned ICOs) can fall through.

The only ICO which has a patent is not owned by the company. It is also a ML related patent nothing to do with cryptocurrency.

The worst part is the author gives a checklist of things to consider but conveniently omits how the checklist applies to these ICOs.
> The future in long haul is mid-size highly efficient twin engine jets and here Airbus is scrambling to catch up with Boeing in both sales and design

I agree with your first paragraph, but not at all sure about this. Current air transportation is very stratified, but some of its numerous rules could get a major rework in the next N years (N >= 10). Current setup has mid-size sweetspot when optimized on existing rules on routes, airport slots, weather requirements and in general ATC that is over 30 years old.

Even if only parts of the plans get accepted they can change optimizations significantly, e.g. if and when Nextgen allows planes fly directly from A to B (instead of along a few pre-defined segments) it might push sweetspot from mostly mid-size to a bimodal distribution: smaller for small airports, larger between main hubs. Or some other way.
Correct! However, since lithium is abundant, there are so many other cheaper sources of lithium (for instance, geothermal brines) that ocean extraction will never be the cheapest source (although it is sufficiently cheap if it were the only option).
I like the Gen8, limited to Intel Ivy Bridge at best but I have a Xeon E3-1230v2 in mine with 12GB RAM and it works great. If you can find a cheap license for iLO Advanced the remote administration is really useful too.
Flew the A350 and 787 a week apart (recently, via Qatar) - the A350 is a surprisingly quiet machine on the inside.

The 787's larger windows (combined with being tall) means I get an almost 360 view around the plane through windows around me over people's heads (until they dim everybody's windows by default * shakes fist * )
As a gay person I can't safely visit Saudi Arabia either. International events should not happen there.
I agree it is a fixed cost, but the initial cost is expensive by itself before we consider the cost for maintenance. Also 5x for economy is really expensive, I highly doubt that many customers would want this 380 experience for 5x of econ. Airbus 380 is ideal for long distance, then 5*800 from NY to Asia would be too damn expensive: then why not first-class on non-380?
