Nah, you really want to start students learning the GA formalism in their linear algebra and vector calculus classes, if not in high school.

Especially important in high school is to dive into not only the “complex numbers” but also the “split complex numbers”.
A nice change from the LED lighted boxes you often see for high end machines.

I’m hoping they do a nice laptop. HN will need to put their money where there mouth is if System76 comes up with a thick laptop with replaceable battery, upgradeable RAM, lots of non USB-C ports and a keyboard with some travel. A niche System76 could really fit into.

Those computer seems actually reasonably priced. You can get a better deal building them yourself but as a hassle free solution it seems pretty good. Event if you end up installing windows on it. I am quite impressed.
Apple processors always blow away the competitors by miles and it takes them the competitors up to a year to catch up. They have amazing cameras, music quality, build, looks, display, security, etc. If they aren't the best, they are in the top 3. And that is all in 1 phone.

I do not personally prefer Apple cause it is not my cup of tea (and I need headphone jack) but they have been coming up with amazing phones year after year, and you can easily skip a year without it affecting your usage.

They cannot reinvent the wheel every time.

The question is to what extent this is institutional rather than fraudulent actions of a few individuals. It probably is institutional, of course, but innocent until proven guilty and all that.

How would you recommend we measure screen size? Length x Width I assume is the obvious one, but that’s harder to compare. I suppose you could argue comparing diagonals isn’t a good benchmark either, but it works well enough when screens tend to have similar aspect ratios, as they mostly do.

Dunno, they seem pretty huge. The smallest is 14 liters and limits you to 32GB ram? What is this.. an Apple?

Seems pretty insane to charge prices like this ($2,500 for a modest i7, 32G ram, and 256GB SSD) and not make it expandable enough to handle the more challenging uses.
Not surprising. KDE has always been a bit too complicated whilst not offering a particularly great nor modern interface. I know it can be changed to perform more like Gnome, but there's so many options that it just becomes a pain.

Gnome Shell has nice defaults, the extensions are super easy to install if you do want to change something, it looks good and it's efficient to find apps or switch apps. I've personally always liked the Shell interface and I imagine with the proliferation of smart phones, Windows 10 and other modern interfaces, most users are just fine with the new paradigm (versus the start button from Windows 95).

Gnome is stable, easy to use, nice looking and makes a great default. For the enterprise, I can't imagine how anyone would want to deal with something like KDE.
As I understand it, if you ever opened such project in VS, it would replace the wildcard with the current list of files. So the usability of that approach was very limited.
Phones never replaced laptops though. Phone are useful, and yet will never ever replaced the desktop, solely because of screen size. You can't magic a full screen monitor on your phone.

Yes, iPads could be useful for some circumstances, but power was never the limiting factor.

Take an iPad from 5 years ago, and you have something that works just as well for all iPad usecases.

My point is that I don't think anyone could imagine sitting 8 hours a day, typing away at an iPad.

For office work, a mouse and keyboard is essential.

How can you possible spend hours typing away at something that doesn't have a keyboard? And the vast majority of office usecases involve lots and lots of typing and mouse usage.

An iPad being useful is not the same thing as replacing office work.
False self-employment is a situation in which somebody registered as self-employed, a freelancer, or a temp is de facto an employee carrying out a professional activity under the authority and subordination of another company. Such false self-employment is often a way to circumvent social welfare and employment legislation, for example by avoiding employer's social security and income tax contributions.While a modern "gig economy" encourages more casual employment practices in the interests of labour flexibility, the extent to which this disguises precarious employment and denial of rights is of growing concern to authorities. https://en.wikipedia.org/wiki/False_self-employment
Me too. These look incredible. Does anyone know if you could also turn them into Hackintosh or run Windows 10 on them for gaming? If so, I'd pick one up in a heartbeat.

I'm a little concerned that the custom I/O daughterboard might make them only compatible with Linux or the PopOS (custom Ubuntu) that System76 offers.
Exactly they cannot keep inventing the wheel.

> *...one of the things the program found is that the drones are not good at seeing through tree canopies. This is surprising for me...

Yeah, if you dig around a bit you can find infrared and near-infrared images of trees and forests, and overhead IR shots of forest canopies. Trees give off a surprising amount of IR.
In my opinion, the problem is not the geometric product, but having three products (inner, outer and geometric). I have explained GA using a single product, and I think it is much clearer.

Of course, the inner and outer products are also very useful, but I introduce them only at the last stage, as some extra notation, not to help understand new concepts.
I get that. I just have a hard time thinking that is "generalizing" the model, so much as making the model all encompassing.
Of course it won’t ensure anything, but currently being completely unable to reproduce results, even as the author but just a year from now, is par for the course.
Hopefully Core 3 has better serial port support. I've run into all kinds of edge cases for serial ports where things work great on the .Net framework but are flakey or non functional on Core 2. It's my only major complaint about .Net Core.

I would replace the last two operations by another multiplication and one reciprocal square root. There is extensive SIMD support for very fast approximations, and getting better in newer chips.
I regularly install the current ubuntu LTS on about 5 desktops, all with nvidia. Generally it just works you either have to click on (settings -> drivers -> nvidia) or just do an apt-get install nvidia-<current version>.

When there's a kernel upgrade it "just works", presumably with DKMS or similar. What pain are you seeing with nvidia?
I'd say that bhyve on FreeNAS is pretty stable. It is not THAT green anymore, it has been there for a few years.

It is also not as slick or feature rich as say any VMware product, but it does what it has to do. It runs VMs and I've seen the VMs survive a few power outages as well.

As always YMMV
In Gnome Tweak you can adjust the text scaling to any factor you want, to the decimal. You can also choose whether or not you want sub-pixel hinting and if you want anti-aliasing. I'm using Fedora 29 right now for the record.

I can’t speak for GP, but Nelson invented hypermedia/hyperlinks and had a vision for the future that included documents including other documents. All of that seems pretty compatible.
Creator's probably could have went in the direction of a deep-dive into Apu's family. A smart-mouthed son, a bookish daughter destined for success at intellectual pursuits. They probably speak English in the same way that kids with parents whose families immigrated a couple of generations earlier did. I mean, yeah, news flash, first generation immigrants typically have thick accents. Their kids typically turn into very 'normal' Americans. Political correctness gone haywire, absolutely. They erased that story, instead of embracing it, and it really is our story.

Edit: And for what? The stale antics that the show has become known for over the last decade? God, what a missed opportunity.
Ask HN: Which industries are the most varied in total comp? Most homogeneous?
I'm trying to get some guidance as to where to start looking for variance in total compensation, which usually correlated with work-life balance and career growth, among different industries. My first guess is that the heavily regulated industries like healthcare have less variation in total comp.

As a software engineer, I know that the bottom floor of compensation scrapes minimum wage in some companies, also usually they are least desirable for quality of time and work. The only one I can think of where the floor doesn't get that bad is perhaps doctors. There are tiers of pay there too, but the bottom floor is usually high for them.

Is there any research or dissertation done on this subject? Or even just a list ranking several fields from most homogeneous in total comp to least.
Do you need mass equal to earth, or mass slightly greater than whatever you're launching? (Alternatively, does antimatter experience the opposite force of the same mass of regular matter, or is it something else?)

If antimatter has negative mass in the context of the gravitational equation (F = Gm_1m_2/r^2) then you just need more antimatter than matter (by mass). Of course, that also means general relativity is incomplete.

That's not to say launching/lifting something on an antimatter platform would be practical anyway. There'd be issues around how you keep the platform and payload together, let alone the difficulty of constructing an antimatter platform in the first place...
It's really refreshing to see such a clean design, especially from a committed open source vendor. I don't even really have a need for a desktop right now but it could be nice having an "anchor", so to speak, instead of being mobile all the time.

Resignation and post-mortem (1999)
I work in building design and we produce a lot of documents common to every project. The industry still really loves their paper. I use google apps script to track project information in spreadsheets and autogenerate the necessary documents, then auto email them to the right people. Haven’t been doing it for long, but so far so good.
I've had multiple instances of production data corruption with MongoDB. One of them unrecoverable using normal tools (as in, exporting data or attempting to replicate it just outright failed). Luckily that was a non-critical system, but if it hadn't been, it would have been a disaster. Hundreds of gigabytes of documents were unrecoverable, at least by our database folks.

The bigger issue I've seen was that some major ORMs were relying on some (apparently undefined?) behavior regarding the positional operator with nested collections of documents, and that behavior changed with a minor version. It's harder to blame MongoDB for that one, but the data corruption was cancerous – it multiplied on every document save.
They are so unwieldy. JSON formatting means the ipynb format is a huge mess to handle by simple means, so you have to open a browser window to do anything. Loading, editing, formatting, saving is just... ugh. You can't do proper diffs (though some tools are trying to alleviate that). Loading, stopping and restarting kernels is excruciatingly slow. Because cell execution isn't necessarily done in order it can become very, very easy to lose yourself and feel like you're back in the 70's experiencing GOTOs and the joys of spaghetti code. And that's from my point of view with a technical background. Imagine explaining notebooks to a biologist to whom writing any line of code is still something new and daunting. Imagine their reaction when they happen to mess up one cell in their own execution order and alter all the subsequent workflow, try to grok some of the magic %commands, or get some cryptic error message due to some config file not having the proper rights because they installed a library with 'pip --user' and not 'sudo pip'. It's not realistic to think that an entire community of people who aren't technically minded, many of which actually loathe or fear anything looking like code, is going to adopt a tool that even technically minded people struggle to use they way it's intended.

On top of that, many steps necessary to reproduce a pipeline typically need to load enormous datasets. Terabytes of simulated protein structures, hundreds of gigabytes of sequencing reads, phylogenetic trees, alignment files, what have you. Once you somehow acquire that dataset, you need the appropriate tools, many of which need to be specifically compiled for your platform, then run them onto a powerful machine if you don't want the pipeline to take months to complete, etc. (And that's if you didn't use any proprietary software or any GUI based application with no command line interface.) You can't exactly load all of that into Github+Mybinder and call it a day. You can't ask a community of people that doesn't like coding to learn about Docker containers either.

Nevertheless, we (at our lab) do use notebooks when we can because we know they're fashionable. We can only present parts of our results, though, due to the aforementioned constraints, but it's still pretty looking and people like them, so we write short demos using them.
I learned about differential forms in my physics degree, and then later discovered that the exterior algebra made a lot more sense if you introduced it separately. Basically it seems like the exterior algebra is useful in many settings, and differential-forms are just one rather confusing application of it. My current opinion is that exterior algebra should, someday, be taught first (around the time of linear algebra), and then later extended to differential forms when derivatives and manifolds get involved.

I agree that the Hodge Dual is easily the worst part of exterior algebra. But you can treat the inner product as more fundamental, via *a ∧ b = <a,b> i. Either can essentially be constructed from the other (iirc).
Most of those other systems don’t claim to be designed to prevent them intrinsically via process, though.
I've been using my System76 Oryx Pro for two years and I love it. It's a powerful laptop and every piece of it is well supported by Linux. I run Arch, since I'm not a fan of their Pop! OS, but it's a great piece of hardware for a Linux user. However, I've been really craving something more powerful, for gaming, rendering, and compiling, which still has the Linux-by-design support and quality build.

It looks like System76 has delivered precisely that series... and at a reasonable price. Thank you guys!
Black holes destroy information don't they - they would be neither matter nor antimatter. Nor energy, for that matter. They're just point mass. Which implies that both matter and antimatter would be attracted to the black hole equally, but that kind of breaks the idea that antimatter reverse-curves spacetime, doesn't it?

So anti-black-holes would have to exist in a "antimatter has antigravity" universe, wouldn't it?

Which contradicts the idea of black holes destroying all information.
In addition to themes they also want to get rid of extensions.
Syntax-wise it's a lot like Java, but without a lot of the stuff that makes Java verbose and tedious, and with the addition of a lot of extra features that allow for much more rapid development. Groovy is dynamically typed, with optional static typing, supports closures, currying, etc., has good support for many other FP primitives, but also fully supports OOP, can seamlessly use pretty much any Java library, has great metaprogramming support, and probably a number of other things I'm forgetting right now.
Most statisticians work for people who are trying to sell something. Statistics is not always the best way of selling something.
> it's never going to be powerful enough to enlighten the surrounding culture

But one of Kay's central arguments is that literacy (meaning reading/writing media, especially print) did precisely what you are saying isn't possible. If computing is such a medium, we can't even imagine what kinds of enlightenment will be possible -- the same way oral cultures cannot imagine the ways of thinking of literate cultures.
Actually, most of the packages in openSUSE related to KDE software are handled by community people: two SUSE employees are part of the team, but they don't work on KDE stuff as part of their day jobs.

Sounds like someone is jealous they're not worth 34 Billion...
They look nice, are pretty large. Very few specs, I couldn't for instance find anything mentioning the size of the fan.

From what I can tell it's a bog standard system, a thin piece of wood (or is it a veneer?), and a custom fan controller on a small daughter card.

The integration is pretty nice, presumably all the driver related integration "just works", although I generally get that with dell desktops or newegg systems built from parts.

They don't mention much about the actual quality though. How efficient is the power supply? How many fans does it have? Any sound insulation inside? Maybe a aluminum/plastic/aluminum sandwich for sound dampening?

Why is the rear fan so far from the rear of the case?

Why is the motherboard horizontal which makes the case very wide, especially for a machine with a max of 32GB ram.

For $2,500 for a modest i7 system with 32GB ram, gtx-1070, and a 256GB SSD I was expecting more than a custom fan controller and limited ram.
The exciting part is not the case, nor the specs, nor the OS. The exciting part is that they are attempting to use open hardware and firmware to the greatest extent they can practically achieve.

They have created an open source "daughter board" for this purpose.
The geometric product is super useful and important! (As well as much nicer to work with when doing algebraic manipulation.)

In particular, it is what lets you take products, inverses and quotients (assuming the denominator is non-null) of arbitrary vectors.

> surprisingly hard to compute

Hm? No it isn’t....

Several times in the last few years I have done several pages of complicated calculations in terms of coordinates or matrices, where the intermediate steps were basically an indecipherable mess of symbols, and then sat down, really thought about what I was doing for a while, and re-written it using GA language and ended up simplifying my work down to a few lines of simple algebraic manipulations, where I could typically then give a nice geometrical interpretation to each step.

If you want to compute the geometric product using concrete numbers in terms of a basis, then it is straightforward to write the code (or work through by hand).

What is hard is not the geometric product. What is hard is geometry! There is a lot of depth and subtlety, and it takes years to really learn your way around. That is not the fault of the language though; there is a certain amount of irreducible complexity involved.

Personally I would love to get some people together and try to write a high-school-accessible geometry / vector algebra book using GA language. It would be a few years of hard work, because figuring out the right order for the curriculum, the right types of problems to build intuition, which tools to include or leave out of an introductory book, how to best show the work for a whole collection of worked examples (ideally with some interactive computer diagrams), and so on.
No, gravity is time symmetric!

Imagine throwing a ball up, and watching it fall back to your hand. Run the clock backwards and it looks exactly the same!
How do you propose focussing something that is uncharged and thus insensitive to both electric and magnetic fields?
It's much harder to automatically remove if it isn't static.
If earth is falling towards the sun it is due to higher order effects, like friction or gravitational waves. It's not due to gravity itself, which is time symmetric.
Of what I've understood, the loading is watched by guards (of the banana company for example). And each guard is responsible of its containers it supervises.

Thus, once it arrives in the country, if cocaine is found, then customs will call the other country (I suppose that they have treaties in place) and ...

Also, they said that the majority of the drugs are injected after closing the container, thus proving the utility of these tamper proof bolt seals
Thanks!

Oh wait, not me. Got it.
The essay mentions Jonathan Haidt's "The Coddling of the American Mind", so I will chime in with a pertinent excerpt which has data that the essay doesn't mention.

>A 2016 report by the Center for Collegiate Mental Health, using data from 139 colleges, found that by the 2015–2016 school year, half of all students surveyed reported having attended counseling for mental health concerns. The report notes that the only mental health concerns that were increasing in recent years were anxiety and depression. Confirming these upward trends with a different dataset, Figure 7.3 shows the percentage of college students who describe themselves as having a mental disorder. That number increased from 2.7 to 6.1 for male college students between 2012 and 2016 (that’s an increase of 126%). For female college students, it rose even more: from 5.8 to 14.5 (an increase of 150%). Regardless of whether all these students would meet rigorous diagnostic criteria, it is clear that iGen college students think about themselves very differently than did Millennials. The change is greatest for women: One out of every seven women at U.S. universities now thinks of herself as having a psychological disorder, up from just one in eighteen women in the last years of the Millennials.
