Gauge theory is the collection of techniques used to describe forces in quantum field theory (electro-magnetism, weak force, and strong force). In field theory you have many vector spaces (1-d, 2-d, ... n-d) defined for every point in space time. So a specific field requires a distinct vector value for each space-time point. These fields encode certain particle types like electrons, quarks, etc.

One can ask, how can I compare field values at 2 distinct points a and b? They are in distinct vector spaces V_a vs V_b. Well, gauge theory says you must imagine the vector v_a being moved along a path between a and b, and see how the translated vector value compares to the vector v_b over b. This is called "parallel transport." A rule about how all vectors move along all paths during this translation is called a "connection." These connections encode distinct force-carrying particle types like photons and gluons. Sort of like how an object naturally rotates along a curvy surface. It's naively possible to describe this transport, this curvyness, but the natural notation is such that distinct descriptions are actually the same connection. Dealing with this ambiguity is key to properly computing probabilities using path integrals.

By the way, each gauge theory is required to have an underlying "gauge group," meaning a set of possible symmetries. In the standard model these groups are called U(1), SU(2) and SU(3). U(1) is 1-dimensional, so only 1 kind of electromagnetic force particle, the photon. SU(2) is 3-dimensional so 3 types of weak force particles (W-,W+, and Z) and SU(3) is 8 dimensional so 8 types of gluons.
A Rural Community Decided to Treat Its Opioid Problem Like a Natural Disaster
That and there were things that, yes, might've taken a little time to maintain, but at least gave it a 'face' outside of normal corporate BS such as being able to share stuff with friends on there. Also, star ratings going away, I think reviews are gone now too, as well as the ability to dismiss things you aren't interested in the past (I think that disappeared a few years ago).

The UI and findability sucks if you're on a PC but is fine if you're on a big screen tv (which is the direction I assume it's been aimed in, as well as big buttons for touch screen or visibility). When I was subscribed, I would use a third party website like instantwatcher to easily sort and search what so I could browse quickly.

Recommendations and the whatever algorithms they're using now aren't very useful (maybe coming full circle on the limited content leading to limited choice).

> For one, "no additional per-request overhead" is an oversimplification…

That's fair, but setting aside packaging decisions like code-splitting (which aren't unique to SPAs), my point is that SSR is typically used to deliver content and app logic that would otherwise require round-trips to code running on a server. It hardly seems like a huge win for "SimpleSSR".
By using the obsolete software versions, it cause instability and inconsistency and a lot of effort will be wasted to workaround the issue rather than solving the real problem.
I've seen those links. Is there some particular evidence you're pointing to? Or a position statement by experts concerning a convincing physiological mechanism?
I recommend the pynq from digilent, it'll help ease your way into hardware design.
> that is both dynamic and can be compiled

JavaScript is dynamic and compiled (as are many other dynamically-typed JIT languages). Did you mean dynamically typed and optionally statically typed?

> Runs on a VM and on bare metal

JavaScript is also runs on a VM and bare metal (e.g. V8's Ignition interpreter will interpret JavaScript, but TurboFan will compile it to machine code).
You can, but the thing is that unlike with emails, with Slack most conversation happen in public and no one has to CC you in email (or rather remember to CC you in these convos) basically slack replaces CC and BCC part of the email really well
The speeds I listed were not averages, but instantaneous; the purpose were to outline the speed difference between different moving things that share the path.

Yes, more or less any grownup in fair shape can pedal 40 kph on a flat, as long as they don't run out of gears. Maintaining over 40 kph average (which means going much faster at times) for the duration of a long race is a completely different thing.

And yes, some people actually like to sprint like hell for fun. Sometimes I do too.

Think about it for a moment. Club cyclists often aim to average around 27 kph for something like a 80 kilometer trip. Hitting 40 on a nice flat or downhill section on your commute of 3 km is nothing.
> Their software support is something else. I haven't had to use IBM tooling in a while, but back when I did, everything they sold was absolutely fucking terrible (DB2, RAD, WebSphere, Clear Case, Tivoli) compared to many open source equivalents.

Over 20 years in contracting that's been my experience too, utterly lazy, awful software - awful UI, continuous license issues, buggy, juggernauts of bloat. WSAD (Eclipse + Websphere plugins) was easily my worst experience with an IDE, ClearCase easily my worst experience with a SCCS etc. I pity people that have to work with any of it 9-5.

The banks and insurance companies I've worked at had support contracts, but they were useless - you more often than not just had to suck it up.
I can see "some of the most vitriolic and racist garbage I've ever seen" on Twitter any day I want. Granted, I don't want to go on Twitter that often, but finding garbage there is not a problem. I mean, https://twitter.com/louisfarrakhan exists and this is the person who literally talks about "Satanic Jews". Why it isn't a walking PR disaster I wonder?
It teaches the same first principles in a smaller format with less room for error, but this particular board won't be able to scale up to a prod environment.

Agree with another commenter that an AWS EC2 F1 instance might be closer to prod for your purposes.
It‘s kinda sad that there‘s currently no more intuitive, built-in, simple and elegant better way to do that.

(I know of thousands (if not infinitely) more complex ones so please don‘t start on them)

It must be as simple as „google that and press install“. Everything requiring an install has a huge negative attached, but the worst is if they google for the tool you use to then type in ... . Maybe make the tool the start page and train them to press the startpage-button first every time you tell them to „google sth“.

You‘ll miss a business model though incase you don‘t want to show links to crapware like certain others.

Or maybe just make DuckDuckGo the startpage?
While this is good advice, it seems as useless as all the other "just quit doing <whatever bad habit you have>" advice.

What are some techniques that folks use to convince themselves to only worry about their shit and not dwell on shit from other people?
That made me think about something else. How cool would it be to have a program visually show you how a string is stored in memory?

This way you would be able to interactively see how unicode and different runes are represented in bytes, how they are also abstractly represented in your programming language array data structure, and how finally they are stored on your little-endian system.
This abuses the word "plot".

These aren't plots, they're highest-level structures. They're also merely all six alternations of up/down across two and three combinations.

"From bad to good fortune" or "From good to bad to good" isn't a plot.

"A young man leaves his town in search of adventure, his talent is quickly recognized by the military and he leads a platoon in battle which wins the war and he finds the meaning in his life he'd been missing" is a plot, albeit a very basic one.
>Any bets on whether Fedora and CentOS will exist in November 2019?

I would say that Fedora and CentOS aren't going away anywhere. Not because of this anyway. There were similar concerns around RH's acquisition (if that's what you call it) of CentOS a couple of years ago, but things have largely been the same. And it's mostly for selfish reasons. The overall dev mindshare of RH based systems has shrunk compared to Ubuntu. So anything that moves people away from Ubuntu to the RH ecosystem is net win because eventually some corp will write a check when they need support. It's the same idea as MS not going after pirates just to increase MS's overall market share.
It's been quite clear that their IT service shift was sad. The rest is still pretty pretty.
Been working with this implementation of WFC in Unity and it’s been a lot of fun. The game Bad North that just came out also uses this technique heavily for 3D island generation.

The analogy isn’t 1:1 but I think the core of MS and what he was doing in the cloud division might as well had him an outsider. MS was still highly Windows first all others second under Ballmer. Under Nadella he bet the future of the company on cloud and it’s been the right choice. What if they do the same with a changing of the guard — not immediately but eventually?

Can you really benefit from this new skill? Because it is very different from GPU programming. In fact, it is mostly describing hardware in some very low level language. You must develop everything by yourself to make that eGPU functionality. All cards are good, you just need to pick right one for your application. Terasic has a nice range boards starting with cheap ones for beginning to advanced ones with high end FPGAs.

"Quit worrying about what everyone else is doing." - Good advice.

"Focus on how you're helping people." - ?

How come is 'helping people' ultimate goal? "Focus on what you are doing." looks as better advice?
jessriedel, the consensus is that this is a physiological disease with an unknown mechanism. That's why it's an area of active research.

I don't know where you get the idea that the null hypothesis for the cause of any set of symptoms not explained by known biomarkers needs to be "psychosomatic disorder". That's not even wrong - it makes no sense.
Yeah I guess that's true. And I guess you could use TypeScript if you don't like Javascript.
There are dozens of writing mentors/gurus, and every one of them has discovered the story structure, or the 3/7/10/50 basic plots. All of them are different. From vague and meaningless "beginning-middle-end but not always in the same order" to Blake Snyder's Beat Sheet or Dan Harmon's story circle(Campbell's hero's journey).

They all are kinda true, for the same reason you can find the proof of UFO in the Bible, or determine that there are "two kinds of people", or discover 4 personality types. Anything can be shoehorned into any kind of pattern if your definition is vague enough and you're willing to stretch the meaning of things hard enough.

Different writers are familiar with different structures and use ones they prefer, bending and modifying them as they wish. Some writers break the rules on purpose. Some writers get high out of their minds and write stream of consciousness novels in a weekend. Any of that can result in a great/famous/successful story. Finding the pattern that fits all of that is only possible if it's so vague that it can fit literally anything, at which point it becomes meaningless.

Plots and story structures can be picked up and used when it's convenient, it's easier to write when you have a paint-by-numbers structure to hang your story upon, but there isn't the one story structure or the six story types, that's silly.
This was to be expected. Red Hat had no future as an independent company. Their flagship product RHEL still dominates their revenue 20 years later... But they have already saturated the enterprise Linux server market, and that market is in decline. All attempts to diversify have failed. Openshift and Ansible have potential, but compared to the decline of their core business, it’s too little too late. The current CEO is a peacetime CEO: he managed a successful business competently in fair wheather, but is not fit to navigate the rough seas ahead. This allows him to leave on a victory (“the largest software acquisition ever!”) and go on a book tour or something. Meanwhile IBM can delude themselves a few more years until they’ve finished milking Red Hat’s products for easy growth. Then they will have to face the reality of their situation: they have no real answer to Big Cloud eating their lunch. For now, though, they can pretend this is it.
... and yet there is no shortage of examples of ownership being consistently more concentrated over time. Are we are right around the corner from seeing "upstarts" in the television, telecoms, and food manufacturing industries?
A field theory is a theory that describes a physical phenomenon by fields and how they evolve and interact over time. A field is just a function that takes a point in space and time and gives you a value. You can model temperature as a function that given a point in space and instant in time gives you the temperature at that specific point in space and time. Or the wind velocity which will assign a vector indicating the direction and speed of the wind to each point in space and time instead of a single number as in the case of temperature - this is the difference between a scalar field and a vector field and there are other types of fields like tensor fields. A field theory then provides you with the equations that explain how fields change over space and time and how they interact with each other in case the theory has multiple interacting fields.

A gauge theory then is a special kind of field theory, one which is invariant under some symmetry transformation. You could for example come up with the idea to describe temperature with complex numbers instead of real numbers. The equations wouldn't really change, they would essentially just ignore the imaginary part of the temperature making 20°C, 20 + 42i°C, and 20 - 7i°C three different representations of the same temperature. In consequence you are free to adjust the imaginary parts of all the temperatures without this affecting your predictions.

As it turns out if you want to use field theory to describe quantum physics and if you want your field theory to have certain nice properties, for example making it obvious that the theory respects locality, then you are forced to use gauge theories, i.e. you are unable to write a field theory without those redundancies where several different values correspond to the same real physical state. In the example from above, the real temperature is of course 20°C but because of the way you would like to formulate your theory, you are forced to use complex numbers for the temperature and because the resulting theory is so nice to work with you accept this and just declare that all temperatures with the same real component are the same regardless of the imaginary part.

And while you often hear that the world is fundamentally made out of fields, that is not true, or at least it does not have to be true. Quantum field theory is one of our best tools to describe our world but the fields are just a nice and convenient mathematical tools, they are not in one to one correspondence with actually existing things.
IBMs revenue comes from consulting but a lot of their profit comes from software https://www.quora.com/What-is-the-split-between-IT-and-consu...

In their latest quarter https://www.ibm.com/investor/att/pdf/IBM-3Q18-Earnings-Chart... $4.1b of revenue came from Cognitive Solutions (mostly solutions software) at a 76% gross profit while their global business services with the same revenue had a gross profit of only 29.8%.

By the way, they spend $1.3b on RD&E while their net income is $2.7b.

I previously commented in https://news.ycombinator.com/item?id=18322772 with a bit more context on how I view this deal.
I don't think it is possible.

Any data on your computer, phone or online is already compromised or can be at anytime.

I don't think private data exists.

There are steps you can do to help keep data more private but nothing reliable or for sure.

If it's online or in your phone I'd assume it's not secure.
An an IBM employee, I definitely hope that some of the RH culture rubs off on us, but I also hope that RH retains its own distinctive identity and isn't altered very much by the deal aside from having access to IBM's resources such as the scale of the sales organisation.
I mean, Algo traders I know are working on teams of 10-20 people with deep knowledge of $5k boards over a half-decade, so I think for "getting started" those might be pretty good.
Yes, it's 14.04. I tried 18.04 a couple of weeks ago, but I didn't really like the new GNOME interface. For me, Unity was (is) a great DE. I know other things improved too, but I'm not really enthusiastic about them either. For example, snaps, whose paradigm of self-contained applications I don't consider an improvement.
I'd assume after the 5 years you still have the car, or at least sell it for something rather than scrap.
We allow strangers that haven't had their driving or eyes tested in 50 years drive us down the highway (Uber). We allow strangers to operate hotels out of their homes (Airbnb). However, we can't allow a stranger to cook us a chicken breast or prepare a soup?

There isn't a world of a difference here. They all present minor dangers, and I'm willing to take the risk of buying a piece of lasagna from my neighbor.

My wife suffers from CFS, and for the first two years, she was pretty much bed ridden. The first six months she couldn't even read in bed because she was so exhausted she couldn't concentrate enough. Lucky we had a dog to keep her company.

We tried various techniques through the years including modafinil (and sleeping tablets at night to counteract that), but nothing really worked beyond a temporary solution.

These days (7ish years later) she can work full time as long as she maintains her energy envelope. So doesn't do much on weekends, needs to rest up.
Do you think Ubuntu has a future as an independent company?

Unfortunately, research into this disease is hugely underfunded relative to its societal impact. Even if it is a biopsychosocial condition, which I highly doubt, its effect on millions of sufferers begs for proven solutions. One of the more promising avenues currently is the metabolic trap hypothesis:

https://www.healthrising.org/blog/2018/10/18/the-metabolic-t...

I've suffered from CFS for 17 years, and spent 13 of those looking for a psychological solution, since all my blood tests were fine. Finally accepting the physical nature of my condition has led me to pacing my exertions so as to minimize my symptoms, which is a huge improvement. I would be completely willing to accept a psychological cure today if it actually worked. The best biopsychosocial research is the PACE trial into CBT and graded exercise therapy, which has been highly controversial in its methodology, but even taken at face value, has shown only marginal improvements, and certainly no objective end to disabling symptoms for any significant number of sufferers. (I'll let you look that one up since most sources are highly biased either pro or con.) I myself have tried both CBT and GET multiple times with no improvement in my condition.
I previously visited nexjs.org and read the docs, and it wasn't clear that Next.js is a full-stack framework. The term "full stack" isn't used anywhere at nextjs.org[1], unlike rubyonrails.org[2].

Furthermore, there are numerous references on the web to Next.js being a front-end framework, including statements made by Next.js maintainers[3]. Do these statements not reflect the current state of Next.js?

If Next.js is a full-stack framework, then this seems to be another instance of JavaScript tools having inadequate documentation. Speaking of which, if Next.js is a full-stack framework that's comparable to Rails and Django, why is the documentation just one page (!) and there's no mention of database migrations or other basic features that are included with every full-stack framework?

The only downside is when I was using it the software was only for windows and very bloated.

Ask HN: Share your best OPML/RSS Feeds
