> but even in the absence of matter I think there is a U(1) gauge symmetry present

I don't think there is. The local U(1) gauge symmetry really comes from the (complex-valued) Dirac field and its coupling to the photon field (i.e. A). In classic electrodynamics you can add the 4-gradient of any function to the 4-potential A without changing the equations of motion, so the space of valid gauge transformations is infinite-dimensional. (Which is not that interesting – given that you can't measure the potential A –, so all those degrees of freedom are non-physical.)

> I agree that the A_\mu transform as the coefficients of a differential form (A is a connection after all), but the notation elides the fact that the A_\mu are defined only on U.

That's a very good point indeed! Though I think the authors simply interpreted A as a regular vector field on the manifold, meaning that it is defined everywhere. But following your train of thought for a moment: Could you solve this issue through a partition-of-unity argument? I.e. cover the manifold with neighborhoods where you have local gauges and then construct the metric locally as a finite sum of those A_{\mu,s} (s being the gauge).

The issue of a metric constructed this way not necessarily being a Lorentz metric (let alone non-degenerate) of course nonwithstanding. Then again, the authors didn't worry too much about this, either… :)

Postgres FTS is normally quite good.

But it does not know how to deal with languages like Chinese, Japanese and Thai.

For that you have to use something like PGroonga extension.

The rest of PostgreSQL mostly handles things ok, unless you try to sort on one of these languages and the same things happen again.

There are all ways around these problems. But it’s not as easy as turning on Unicode and just expect everything to work!

> I think one big reasons why RTS are having trouble is, that loosing in an RTS, as a new player, can be one of the worst experiences in gaming

Famously one of the Default Taunts on Age Of Empires 2[0] is *You played for two hours to die like this?*

[0] https://ageofempires.fandom.com/wiki/Taunts

But can't but agree with the general angle, MOBA's in general are less punishing to players at a deep psychological level, StarCraft 2 "suffered" from what the playerbase called "Ladder Anxiety", which was players simply unable to deal with loss and loss aversion as a consequence of them tying their own ego and self-worth to how well they fared playing StarCraft, to the level that Blizzard on one of the expansions had to release a mode where players simply would not lose MMR/ELO points from loses nor earn them on wins, a ranked-less mode and that alleviated a considerable amount of pressure

> So I guess with the overall growth of the gaming market and games becoming more and more expensive, the small community that actually enjoys RTS isn’t really „worth“ that money.

Yeah, this is very much the case, at least for large AAA productions and companies, tho AA studios such as KingArt Games or Sunspear Games have been making inroads into creating new RTS titles which make me very happy as an avid RTS fan

Parents need a break from constant mental engagement with their children; taking it while the child is fully engaged in something like dance practice that doesn't requite the parent’s involvement can enable them to be more fully and functionally present when they are actually needed.

I have a Moonlander from ZSA. Flippin' sweet keyboard.

I have a layer for mouse movement with wasd. On the same layer, I've bound hjkl to the arrow keys, so I can get vimish movement wherever. Below these keys on the same layer I have some browser navigation shortcuts.

I use evil-mode in Emacs. The key below my left thumb is control on hold, escape on tap, and it works beautifully. On my left thumb cluster, I have a key that's option (meta in Emacs land) on hold, and option-x on tap (so I can easily hit M-x in Emacs).

On another layer I have hotkeys to manage window tiling. I use Magnet for macOS; works fine for my needs. One thing I wanted that Magnet didn't have was a half-width-but-centered hotkey; I was able to build that into a macro on my keyboard.

Keyboard macros are a beautiful thing. QMK firmware is the best!

I think I'm late for the discussion, but as a person who grew up in Japan and lived both in the US and Japan, so many things people mentioned here ring true. The thing is that, there are many, many people who want to change, but they're afraid to speak up. Here's my (probably unpopular) suggestions to Japan:

- Fire more people, more often.
- Dismantle lifetime employment.
- Forget perfectionism.
- Destabilize the social hierarchy.
- Stop being polite and be ready to confront others.
- Incorporate more foreigners.
- Learn to negotiate.
- Be assertive.

Basically, we should drop the stereotypical image of being Japanese. Not sure if we can do it, but there isn't much time left.

edit: formatting
Thanks. I think I could understand what u said partially.

We simply do not need to manage talented developers, is my thought.

RTS originate from single player where you don't even need balancing: it's perfectly fine if there is a winning move, the joy lies in discovering that winning move and exploiting it until you happen upon a level that introduces a counter, providing you with the nice riddle of what the next winning move might be. The balanced multiplayer variations, though far more impactful once computers started to be connected, always seemed a bit "is that still fun?" to me.

> is to ensure that end users have freedom to use the devices they have purchased as they see fit

not really. Nobody can or wish to dictate how someone sells a product.

GPL is about GPL'ed code. not products.

> Suppose a company has patented some algorithm ... that also uses GPLv3 code

you keep moving the goal post. Remove GPL from your example!
If that "some algorithm" was built on top of someone else's proprietary (and patented) work, wouldn't they have to satisfy that entity desires on how it wishes to license their work?

The ONLY difference is that GPL only requires that you make your work available under GPL. Easy. Other entities might ask for money. Others, such as apple, would just tell you to F off and you'd never be able to sell the code or the product. Which one is more restrictive or worse?

compare apples to apples please.

I think people in free nations should be concerned about their own governments scrutinizing their actions, whether it's through private date or public. The government is granted a lot of privilege which could be abused, and has been in the past.
I'd be curious to see how the productivity data working remotely scales out for people at different levels. As a new college hire I found that both working in the office and open offices improved my productivity, often explicitly at the expense of productivity for more experienced developers (because they were spending time answering my questions).

In the short term, it would be better for the more experienced developers to be more productive, because their time was worth more, but eventually the experienced developers will leave. If new people aren't trained to replace them fast enough, the system becomes unsustainable.

There are several other areas where eliminating certain activities provides short-term productivity gains at the expense of long-term cohesion. All hands meetings about company direction can be delayed for a month with no negative impact, but if I skip all large company meetings for a year I'd have a much harder time prioritizing tasks (it's unclear which contribute directly to the company's long-term plans and which are busy work) and no idea how to route serious issue only tangentially related to my team.

It's entirely possible there's a looming but currently well-hidden pipeline issue companies are anticipating and trying to avoid.

I have a dedicated macro pad (a duckypad https://www.tindie.com/products/dekuNukem/duckypad-do-it-all... ) and I use it extensively. I have macros for lots of IDE commands, window management, launchers etc. I'm not so great at remembering keyboard shortcuts, so having the macro pad, especially one with a screen that can tell you what each button is, is a boost. I use every key on my pad frequently.

I have a programmable keyboard that I could use to achieve the same thing, but I really like having a dedicated device and find that I use it more than if it was just a function layer in QMK. IMO this is also one of the legit uses of individual key RGB on a keyboard beyond just bling-- you can color code keys.

> since there is no "local global warming"

There is, though. Climate change has different impacts depending on where you are. Some areas are rising in temperature much much faster than others. The arctic is a good example of 'local global warming'.

> I'd be very surprised if the feedback effect is at all significant

Prepare to be surprised. Even if there are 1000 factors each of them only contributing .1% to the total, it is still the case that each one of the 1000 factors is significant.

I can't find anything about "thrown out because the claimant was proved to have stolen money/scammed Riot and falsified the claim"; the closest was Wired in March ('The three-person special committee, a part of Riot’s board of directors, is made up of Youngme Moon, a professor at Harvard Business School and the only publicly-named member of Riot Games’s board. She is joined by two male C-Level executives at the Chinese tech giant Tencent, which owns Riot Games. The company declined to name these members of the special committee.', which seems really one-sided)

I'll agree on Unity, apples to oranges, but 2K/T2 as a company is 3b revenue. EA is 5.5b revenue. Nexon is ~3b revenue.

> I feel a project is right when I can just git clone it (a few megabytes of data at most)

I don't know your experience but especially small projects often have some difficulties installing all dependencies correctly. The fun starts when you don't run a widely supported distro like Ubuntu.

If I want to run an old version of the production software I pull the image version X and execute it.

I know that everything in the package has the right version and works like it used to.

Tests have been executed and the version in the image has proven to meet the standards back then.

> But, I doubt these technologies are a replacement for an ergonomic build environment

If you build software for larger customer bases you will most likely encounter some kind of clustering.

Most large companies have already adapted this way. For personal and small projects it certainly is overkill.

> get some quick feedback on a code change

...wait, do you deploy to prod without tests and no direct way to role back the changes?

"If Elon Musk is one of the richest men in the world and draws roughly a minimum wage salary, is salary really that valuable to building personal wealth?"

These rich boys take out loans at 0, or 1%, and take their pay from that.

I still don't know quite how the tax dodge works? It makes sence. You get a loan, and that is not taxed, and eventually pay it back at a low interest rate. I thought corporate expenditures were scrutinized a bit more though?
So in your opinion these cultural elements have disappeared? Common law, Christian morality, nationalism are all alive and well in most of European countries.
In my experience, 'the phone' is a proxy for another issue. Like am I avoiding my family? Am I avoiding thinking of something uncomfortable? Or procrastinating something important? Or avoiding some hard feelings or a tough reality?

As an example, I know of a family where some children of divorce withdrew to compulsive MMORPG gaming. The parents blame the games. The reality is it's the divorce and the kids avoiding the feelings around it. OTOH I've seen families have their own minecraft server where that's a source of play and fun with kids...
Also on simpler BSD's like OpenBSD, bioctl is dumb simple. Setting up a encrypted disk is a no effort task.

On firewalls, PF has a syntax simpler than most text adventure games.

Every time I get into the GNU world, well, I get better HW support sometimes, among a slight bit of performance, but, FFS, configuring a Linux firewall gives me nightmares everyday. Just compare NAT on Linux vs OpenBSD. Or TUN/TAP devices, where in OpenBSD it's just a matter of a SINGLE line at pf.conf and two hostname.if files to define the bridge and the tap device with a subnet. Done. Oh, and sysctl to set IP forwarding, but that was the easiest task on any OS.
Is this a case of contractor over-engineering, NASA downplaying the abilities, both, neither? I don't mean any of that derogatorily. I know you'd rather announce the low numbers and look like champs when you get better than anounce high numbers and look like chumps when you get lower. It seems to be a bit of pride on NASA contractors building things that far exceed minimum mission requirements. I'd hate to be the contractor that gave NASA something that worked exactly as proposed, and then stopped working immediately. While it would be "successful", you'd hate to then be compared to Curiosity

It happens with more frequency and stronger beliefs today on the internet than it ever did before. Rumors spread faster and take hold for longer. The internet is huge fuel source for spreading rumors, not a dampener.

Perhaps I am unsophisticated, but as a regular user of both Windows and Mac - Mac for work - I find Macs to have exceptional UX. I do not feel the pain that is regularly elaborated in blog posts such as this.

Among the best parts that Windows cannot come close to matching:

* I can use it precisely as just another unix machine, with Terminal (zsh is default!)

* Terminal integrates well with GUI tools

* GUI discoverability is straightforward, and Spotlight search almost always knows what I want

* Preferences are unburdened by crufted abstractions built atop one another (Control Panel and descendants)

* apps are clearly files, are easy to interact with using just the filesystem, are well-controlled by TCC, and poorly built installers are the exception, not the rule

* system notifications are respectful, controllable, and not a morass of spam

* the keychain is both secure and easy to interact with for non-technical users

* support.apple.com documentation is correct and easy to find

* "Help" menu item for a system utility never opens bing and searches $utility_name, which is Windows' latest laziness

* Wiping and reinstalling is not an ordeal

* iCloud backup just works

On the whole macOS pleases me immensely in comparison to Windows or Ubuntu+Gnome. The scrollbars are my most salient complaint, but merely launch regedit.exe to see how a GUI might be truly unusable.
