It is funny that people in the aviation business don't treat it as if it was a growth business. That is why Boeing feels entitled to keep making a 50 year old airframe forever. You couldn't do that if you were making cars.

When it comes to environmental consequences aviation is a growth business, the most important thing we can do is address the 737-class airplanes that people ride in, not the widebody airplanes that are advertised in magazines. Too often ideas like blended wing body, hybrid, and hydrogen are used as excuses to delay a 737 replacement. We've been watching this movie for decades but these is enough $$$ going to the media and politicians and nothing will replace the 737 until the Chinese do it with to the C919 and then all the people who brought you this disaster will say they were blindsided. They get blindsided every time because that's what they do.

This is not my experience at all. I do not notice undue delays switching between applications (do not use slack).

No problems at all. This weekend I'm at my parents, I am connected to an old wrt54gl all day long. I have problems with my other laptop (XPS 13) on the same network.

I've been using this machine since late March, I didn't take notes when I configured it but, from what I remember, I only had to make some small adjustments [1] to get things right.

Sure, the PBP is an under-powered machine but, given the right allowances (the software is under development, the trackpad is not the best, suspend is not working correctly, etc), I find it easy to use as a daily driver most of the time.

Apple Approves Basecamp’s Hey
Actually, J2ME was open sourced as well but with one crucial difference: it was GPL v2 but without the classpath exception they used for the regular version.

With the classpath exception, dynamically linking class files is allowed. Normally this would be a form of creating a derived work thus triggering the virality of the license. This is crucial because it meant phone manufacturers could not take the OSS version and be able to ship it without having to OSS all their proprietary stuff linked against it. Sun was making a bit of money licensing J2ME to just about all phone manufacturers. The Gnu classpath was unusable for mobile phone manufacturers for the same reason: it would expose them to its viral clauses.

The Google & Oracle conflict is related to this because when Google bought Android (in 2004?), they ended up using Apache Harmony, which was a newly created project backed by IBM with an Apache licensed implementation of the Java standard library. It allowed Google to opt out of Sun's restrictive licensing deals, dodge licensing issues with gnu licensed code, and at the same time ignore the design by committee style API design that Sun insisted on with the rest of the industry.

Basically, it enabled them to run the whole of Java as they had their own vm and standard library implementation. Given improvements in mobile hardware, this was an obvious thing to want to do technically by that time. After Android shipped, there was little to no point at all to J2ME and it quickly became a thing of the past.

So, when Oracle bought Sun in 2010, all of that had already happened half a decade earlier. IBM pulled the plug on Harmony shortly after the acquisition and Google eventually incorporated much of Openjdk into Android to replace their Apache Harmony based implementation and also to modernize the code base. This is still licensed with the classpath exception; so they can do this.

Thanks! It looks like the novnc package is in testing, not main:

Please note I did oversimplify this a bit. You'll still need something like WayVNC, but it doesn't have WebSocket support yet. You can track it here:

https://github.com/any1/neatvnc/issues/2

In the meantime, you should be able to use websockify (there is an alpine package already).

For a simple app, I'd recommend cage which is a kiosk wayland WM for a single app:

Under normal circumstances Windows' DWM compositor will avoid compositing at the display rate if nothing has changed. It used to be pretty easy to demonstrate this by using a hook application (like fraps) to put a framerate overlay on DWM, though I don't think that works anymore. If you have g-sync enabled for the active windowed application, the DWM composition rate (and the monitor scanout as a whole) will be tied to the windowed application's vsync, so if it's running at 30hz so is your desktop until you tab away. Many G-Sync monitors have a built in framerate overlay you can toggle on to observe this (though the lag on your mouse cursor will make it obvious).

I suspect in practice most software is not very good at giving the compositor the info it needs to avoid wasteful refreshes of the whole desktop, and the compositor probably also isn't putting in as much effort as it could.
Isn't this perfectly logical, as dance has more complicated pattern of highly coordinated moves and in addition requires synchronization with the rhythm. I'd be much more interested in comparison of dance and some more complex fitness activity that requires high focus, say juggling the soccer ball or playing the table tennis or even jumping the rope.
Oh, to me the name in french implied it stored energy.

I use some numbers which are my estimations, and not random numbers. I could explain how I made these estimations if you asked (Short version by definition of risk which is damage multiplied by probability). Also if you disagree with these estimations, you are welcome to suggest your better estimations, how these three scenarios compare to each other.

> your entire justification for this spying is that it could be worse. That reads to me like an ad hominem attack in itself.

It would be ad hominem attack if I said it could be worse for you. But I didn’t, and not everything is about you, so my argument wasn’t ad hominem.

Also, probably best to admit this conversation is derailed and stop it for the good.
There is no way you'd get me on a hydrogen powered aircraft. Hydrogen is a tricky substance to handle at the best of times, it explodes with the least provocation and has a lot of effect on the materials that package it. By then I hope my flying days are over but just in case they aren't that is something that would have an immediate impact on my decision to travel or not.
Current climate models indicate that if we want anything less than catastrophe we need to completely stop producing CO2 in 20(30?) years AND begin capturing it as well.

On a related matter I wondered if there was not something similar that happened to the "Treaty establishing a Constitution for Europe" [0].

As any French citizen I had to vote on it in 2005 and I took the time to read the long document (484 pages).

A constitution is usually a very short document, and a 484 page length is highly unusual, but to my great surprise there were many topics that were never mentioned in the media.

Only 13 pages (Part II: ~2.7 %) are really about an EU constitution.

20 pages are about the EU institutions (4%)

The rest is about other matters, and some of them are very surprising for a a constitutional document.

Some examples:

* Declaration on the Ignalina nuclear power plant in Lithuania

* Declaration on Unit 1 and Unit 2 of the Bohunice V1 nuclear power plant in Slovakia

I always fancy that a secretary dropped and mixed up two reams of papers from two unrelated topics, and nobody anyway took the time to check a document of this length.

You’re trying to solve a social problem with a technological solution. The social problem is that Amazon doesn’t want to fix this. What Amazon wants is more sales, and as long as this kind of thing does not impact what they want, it would be a waste of money to do something which would not benefit them. Meanwhile, Amazon is a huge market for lemons¹ which drives out all sellers except the cheap junk ones, while simultaneously being so absolutely huge that nobody can realistically stop selling on Amazon or stop buying from Amazon.

It's only different for sports because all the coordinating (like of old the activites of hunting and war) applies to a single focus, the body is all maneouvered to the same mind state. In dance, you have to coordinate subtle muscles in precise ways. In sports, the precision is about the particular result you want (a stroke, a kick), but in dance, there are many goals and you need to mind whether your thigh muscle is holding up in just the proper, beautiful way, because the teacher and a knowing audience can tell, much like in musical performances, whether you are really achieving the coordination or faking, or being a beginner. The coordination in dance is of several (and I mean tens of body parts or muscles at the same time) parts having different purposes (supporting the movement, getting balance, showing off, giving impulse, etc) and the brain having to watch them all, all at once. It's much harder to dance beautifully than to swim or run or jump and throw a basketball beautifully, because in dance aesthetics is the primary source of goals for all those body parts, they have different roles or different relationships to the same melodies and harmonies playing over the dance.
> Precisely the problem.

No, problem is to try to assign a moral value to these words, instead of keeping them just descriptive. If you keep just descriptive meaning, you could see that there is not a contradiction between 'terrorism' and 'freedom fighting'.

Some 'terrorism' may be a part of 'freedom fighting', while some not (if the ideological end is different from freedom). And some 'freedom fighting' may be 'terrorism', while some not (if means does not include attacking civilian population, just military structures).

Jetfuel isn't safe, but hydrogen is of an entirely different magnitude of (un)safety because the activation energy required is so ridiculously low.
If my understanding is correct, the goal is to reduce aviation effect on climate change.

There is an ongoing project [1] by US NAVY to turn seawater into jet fuel. This way we would not need to burn fossil fuels and would not need to throw away much of existing aviation technology.

Well that is what governments are for, no-one really wants to pay for tanks and aircraft carriers either. But politicians have managed to convince the public that it is in their best interest to do so.
You needed to have a counterpoint to people paying

For example: carbon-captured or carbon-neutral fuels have a tax advantage (or even subsidies).

The infrastructure around fossil fuels is big, if you can have a carbon-compensated equivalent to that it could be viable.
Why? I think the United Arab Emirates have plenty of land and plenty of sun. Why do they need to use a vertical farm instead of a normal greenhouse?

With a greenhouse, you can control the humidity and water loss. You save all (half?) the light of the leds, perhaps you need some kind of shades to avoid too much light.

Perhaps stacking the farm vertically saves some money in the air conditioning and ceiling construction?
Simple. We all walk in the middle of winter four hours to and from our unheated homes and offices and work by candle light. Also candles cost 45$ for the carbon offset.

I don't think it is, but like you I'll leave the analysis to the reader
The scan speed is exactly the same for all screens when driven by the same timings (resolution, blanking, refresh rate), so there is no difference there. Most digital screens have some processing lag, for gaming screens usually 1-4 ms. This doesn't exist in a CRT. LC panels have a pixel response time, somewhere around 1-40 ms depending on the color change, drive mode and panel type ("1 ms" is always a grey-to-grey transition and generally with overdrive). CRT phosphor lights up practically instantly when hit by the electron beam.

So for a given set of timings, you'd always expect the CRT to be faster, because it represents the absolute minimum time-of-flight delay, assuming it is driven by a direct RAMDAC and not by a conversion box buffering an entire frame or significant portions.

Also, you can "move" electron beams at extremely high speeds. Even in a magnetic deflection CRT like the GDM-FW900 the electron beam can move at more than 80 km/s[1]. In some electrostatic deflection systems the speed of light is exceeded: they can draw a dot moving across the face of the CRT that moves at a higher speed than c. This is possible because "the beam" is a fictional object.

[1] 2304 dots across 482 mm with a pixel clock of around 384 MHz means these 2304 dots are covered in about 6 µs; 482 mm/6 µs = 80.3 km/s.

Ask HN: How can we give positive feedback to open-source projects?
I keep running across quite rude and self-entitled individuals creating or commenting on tickets of open-source (OS) projects. On GitHub and Gitlab I simply add a thumbs-down to the relevant item and move on, lest the pertinent comments or tickets get side-tracked by offtopic discussions.

However, I do wonder if there's more that happy users could do to support OS developers and projects. Besides the obvious donation, I think it would be kind of disruptive to create a ticket to thank the author(s) for their time and work. Tickets are there, after all, to report issues or request improvements of some sort, not for cheer-leading. And often times the emails used in git commits either don't exist or aren't active.

IMO, it is important to find a way to provide positive feedback since the systems we have setup are there for constructive or negative feedback. The later has already driven good developers away from the community and only when they left did the community realise how far the bad elements had gone. Suddenly there were outpours of positive feedback with blog posts, forum posts, comments, tickets, etc. but by then, it's too late.

How can we drown out rude, self-entitled and demanding elements of our community that post things "if you don't implement this, you obviously don't care about your product" with nice things?

I've been in touch with a company called Acxiom, who shared my details on Facebook. I've never heard of it, so I submitted a Data subject request to see what they know about me.

They then asked me to provide my address to confirm my identity. Given that I moved quite frequently, and that I'm now asked to share more personal data with a company who's mishandling my data, I wasn't keen on it.

I mentioned that my full name is globally unique, but they refused. I tried to ask them to share some masked data that I can confirm in full (e.g. "give me a partial address and house number, I can give you the full address"). They refused.

They definitely try to make it hard for you, and to dodge responsibility.

This is true but misleading: yes if your electricity is produced by coal plants electric cars are just slightly better CO2-wise (but cleaner on NOx and other sources of pollution), but the idea is to move away from coal so that running your EV become cleaner over time. (1)
