Show HN: Rag over all physics-related Wikipedia pages
A few weeks ago, during the LK-99 hype, I made a demo app to explain superconductors in simple terms using RAG over relevant Wikipedia pages. I thought it would be cool to extend this to all physics-related Wikipedia pages (which turns out to be ~ 14K). After getting the text and splitting the pages, I ended up with around 100K chunks. I created all the embeddings using OpenAI’s embedding API, which cost around $7. I stored all the vectors in Pinecone.

Reddit Guide to Engineering Resumes
Am working in Data Engineering and get the exactly same treatment:

Have to use some half-assed YAML based solution that compiled into Airflow DAGs. I'm basically a YAML "engineer" wondering what should I write in my resume: "I implemented hundreds of DAGs in YAML", while the other team bags all the credits and pat on back because they made a "great data platform".

BTW how does one get into a real SRE job? Or maybe I should just realize I'm not good enough for most of the "better" jobs out there, and should stick with whatever I have and hop once 4-5 years until retirement.

> while the win32 versions will be kept supported in perpetuity

Yeah.. no. I am surprised people would still believe the claim that Win32 has "good backwards compatibility", specially for games, when even the TFA is claiming that a Windows 7 game is _not_ going to work on Windows 11 without "maintenance".

I'd not go as far as say that all Windows 7 games won't work, but it is definitely a good chunk. And I believe it's getting worse, with Windows 10 era games likely unable to run in "Windows 12". I already have at least one piece of software with runs in early Windows 10 but not in late Windows 10. People are resorting to literally use the Wine libraries in Windows to run old games. At this point, to target a Linux API doesn't seem that bad and likely would even be easier than having to maintain your win32 game AND wine.
Yes, it’s seems like food ordering services should have good APIs for this—why not make it easy for people to integrate food ordering (and paying!) into IFTTT-style hacks?!
Make provides incremental execution of the build graph. It is aware of the dependency graph, and the state of inputs and outputs. It will (ideally) only execute the minimal build rules necessary.

A shell script that checks file mtimes to determine what has already been built, and therefore what can be skipped, is close in spirit.

Make variants like GNU Make have additional functionality, like automatic concurrent execution of parts of the build graph.
Everything you just said, and the consequences for the Russian people, the Russian economy, plus proposal of concessions. It is now known, President Macron spend more than 50 to 60 hours, telling exactly that personally to Putin weeks and days, before the invasion. Did it make a difference?

Reminds me of a different issue we had back at my first permanent iOS role. We wrote about a "button" in the app description, the German translation of which is "Knopf"; this triggered Apple's naughty word filter, presumably because "Knopf" is also a translation of "knob", but "Knopf" doesn't have the penile connotations in German that "knob" has in English.

It is not that trivial, and there have been breaking kernel changes that prevent running ancient glibc versions. Fortunately, glibc is open source, so you can actually patch it to run in older versions.

Just grep a kernel's Kconfig and see how many entries claim "this will break binary compatibility".

Even compilers are not that good at building old software.
I disagree.

There is a strong under-current on HN to be anti-"any kind of psychology/social science/human understanding". There is a belief that humans can't be understood.

Many times there are views expressed about 'humans', or 'reality', with the argument being 'it so obvious to not need to studied', without realizing that the logical conclusion is "Dualism".

Especially lately with AI.

Basically, a lot of HN expresses beliefs about AI versus human, and the argument takes the form that humans are just 'special', which actually does lead to 'Dualism', whether they realize it or not.
As someone who's new to making games (started a year ago), to me it seems that yes, there are open source things here (like Godot), but the process of getting even something simple like 3D camera controls working is so fiddly that it's not worth it. Compared to the cut Steam & co are taking, plus the money you need to pay for other software (e.g. Substance Painter) the UE fee is comparatively tiny.

Looking at the amount code of UE, I don't think Godot & co will truly catch up. There is just no business model that would make large scale development viable.
There is a problem of preserving online-only games - which work in the "game-as-a-service" model. Without a third party / pirate server the games simply wont work. Different thing is that a dead multiplayer game is a dead game, especially MMOs.
If it works I think its hard to call it greenwashing. It might be a bad allocation of resources, if the resources could be spend on more efficient solutions.

It might also be greenwashing if presented as a solution in it self, but as a supplement in the transition it might make sense.
In tech support circles there's a bunch of methodologies, but a common one is PAIR.
Probe, Analyze, Isolate, Resolve.
The first step is probing and gaining agreement - asking meaningful questions to get to the bottom line and then making sure the person understands you have understood and have the right problem in mind.

Many people spend a significant amount of their communication time failing to gain agreement on the actual problem, who was at fault, and how its going to be resolved - this is basic communication skills but many people are not given a framework to think about it and have to go through life getting screamed at, so they adopt a similar policy.
Because wealthy countries pay high prices for fossil fuels, and less wealthy countries can't afford them. If rich countries stop using them and the price falls, there will be a lot of new demand.

Another way of looking at that is: what percentage of the world regularly consumes products that went from one country to another by plane and I think it's probably reasonably high?
She builds upon these theories as her main argument is that Descartes, Spinoza, Malebranche, and James were mostly "fixed" perceptions of physical states. Hers includes more "dynamic" means like sensory input, past experiences, culture/locale, and contextual factors.

But I don't see that. When I read James or Spinoza, I consider the same factors she includes from her book. They all generally believe in the bi-directional power of the mind-body connection and how that relates to someone's driving philosophical system.
That's a good answer, but it doesn't take much questioning for it to break down. What is this "anger" other than its collection of symptoms? If you strip away all of its properties and effects, then what's left for it to be? It becomes rather ghostly then.
Observing anger can be similarly humbling.

You can get ahead of the rush of cortisol enough to watch it happening and remain lucid / disconnected from it, but that's not enough (at least in my experience so far) to avoid the unpleasant physical sensation.
i too have this story from the dark ages of computing, when my colleague asked how to make a pdf from an excel file. i told them to choose the menu item "print", then choose the PDF-program as a printer and then click on "print". they walk away immediately, come back, grumble at the computer... i ask what's wrong "nothing, nothing, tell me again: print, PDF-program and then print, correct?", they walk away again and finally come back "i found nothing at the printer, where is my PDF !?"

mind you, it was 2022
If FY23 sales were minimal, then what are the chances of sales ramping up?

Furthermore, what is the value of each sale? You'd need to sell over $2m at 10% commission in a year to match your previous potential pkg of $320k.

Sales is hard work. Assuming beginner's luck, you would be lucky to make 50 sales in the first year. That means your SaaS would need to be $3500 / month to reach that target.

Pardon me for being cynical, but I think you are being hoodwinked.

There are ways to do this, but GSA just doesn’t do it.

Years ago they used to have a system that would combine all the code.jsons into a single db and provide a query interface. They stopped funding that system and redesigned this static site. But could have used GitHub actions or something to fetch and combine the code.jsons and do everything client side. That still wouldn’t have needed maintenance costs.
This allows you to start up generic machines with no configuration and customize them after boot from a remote host.

It's not so much "on the fly", as it is moving the long-term config storage to a different system.
I remember using some X11 windowmanager way back with desktop resolution higher then the the monitor. If you put the cursor on an edge it would scroll over.

It seems that what is considered good coffee varies greatly. Here in Finland the traditional way to make coffee is very lightly roasted, which makes it quite acidic. Many foreigners don't think very highly of this type of coffee, but people who are used to it often prefer it to "stronger" tasting medium or dark roasted coffees.

I don't know it there's any objective way to determine which coffee is "good" coffee.

I don’t think large organisations can act in such a coordinated manner at all but they can be manipulated.

Cartels with a lot to lose can take their secrets to the grave, in particular if their constituents have a lot to lose. Everyone else has “unfortunate accidents”.

> Makefiles honestly are just glorified shell scripts.

Not really. The concept of a script is "do these things in this order".

The concept of a makefile is "here are a bunch of things that might or might not need to be done, you figure it out".
>The claim is not wrong, for flights.

Sure, but we are talking of hotel rooms and booking.com, not of flights.

And surely large hotel chains (national and international) have their own systems and interfaces to whatever booking system, but booking.com is AFAIK mainly about small, independent hotels, at the most these latter ones have softwares that integrate booking.com reservations into their internal reservation tableau, but (again AFAIK) they also work with the same mechanisms I described for manual interaction, there is a pool of pre-allocated rooms on which booking.com can make reservations.
Guess I've encountered the opposite.

I started a job as a software engineer, first day. The engineering team mostly use Macbooks, my manager asked if I preferred Mac or Windows. I said mac.

I got my Mac, but needed IT helpdesk to set it up (VPN, admin access etc...). I got told there was no ticketing system and for me to drop it off at the helpdesk instead. I did that, but was promptly told that 'Macbooks are hard to set up, so f off...' (yes, he swore at me).

I left stunned back to my manager, he followed up with head of IT and that guy was ordered to apologise to me and was reprimanded. Safe to say I had my Macbook set up within minutes by someone else. Not a great first day.
> It is quite telling that despite all game related NDK APIs being available on GNU/Linux, hardly any studio bothers with making their Android games available on GNU/Linux.

What does this really say, other than even if it was literally technically zero-cost to port a game to Linux, studios would still not bother about it ?

(This is ignoring the fact that I rather doubt we are at the "zero-cost" level and that Android has probably the worst backward compatibility of them all)
Tbf, Apples baroque "skeuomorphic phase" with wood paneling, shiny metal and cloth was absolutely terrible even back then and most likely responsible for the "skeumorphic backlash" that followed. Subtle 3D hints for interactive elements always made sense, and don't need to look "old fashioned".
Probably the most common use case is SaaS providers that support custom domain name for whatever the software it is. For example, a site uptime monitoring service might offer a feature to host a status page on a custom (sub)domain of the customer. The SaaS now needs to programatically create virtual hosts on demand, issue HTTPS certificates, run routine updates, etc.

An API and a web server with small segmented updates make this so much easier. Compare this to Apache, that has to wait to properly end existing connections before reloading, has a config file parsing overhead, and probably does not scale that well with several virtual hosts anyway. There are hardware/File System level limitations as well.
No, the courts have ruled that the law prevents these types of illegal requests. Policy was created to make it easier for the government to follow the law.

> Kennedy's death has had so many worldwide implications

Which implications exactly?

> If the government lied about all that, then what other things the US government lied about? It will shake the very foundations of that country.

I mean... we already know that the government has lied about countless things.

However, Paul Landis is not claiming that the government lied. He's merely claiming that he himself withheld important information from the government.
That would seem inevitable, so the only real question was how much (+2C.) So, how much cooler does the city with many heat pumps get in the winter then?
I recently bought a cheap zink camera and some not-so-cheap zink paper.

Ah yes, Mac OS 8, I have very, very limited experience with it, mostly in the form of one/two-week bursts on taking over from a coworker whenever he went on holiday. It's loooong time ago but on the negatives I remember getting very annoyed with this app called Toaster, on the positives I remember thinking how extremely pretty everything looked (still does) and being blown away by little things like, to set the icon for a folder or document you could just copy and paste one over from another file :)

> I have an infinite number of separate workspaces, each arranged in their own way. I like being able to see and have at-hand everything at once on one screen, which is an illusion best maintained, for me, by a single desktop. Even more than one monitor is more of an "immersion-breaker" than I care to mentally deal with.

I feel exactly the same way but solve it by having an fvwm2 configuration that makes my workspace 3x3 (currently) of the physical screen size and I can scroll the viewport around that to taste.

See https://trout.me.uk/X11/fvwm2rc for my configuration if curious (for a more actual-GUI-ish workflow you'd want to configure more of its features, I generally just have lots of xterms and maybe a firefox - see https://trout.me.uk/screenshot4.png)

Consider another unethical practice: sexual harassment, in many industries, was once so extremely common that there was nothing to report. Everyone in a position to do something about it knew it happened, yet it continued. People reported it anyway. Tanked some of the reporters' careers, but the practice is way less accepted now.

You've completed your PhD, so you're at less risk of backlash. Are you yet in a position where you can blow the whistle on what happened to you?
Wouldn't polar chiral molecules also be distinguishable magnetically simply because they are physically mirrored? Any movement across a magnetic field will cause a polar molecule to rotate opposite relative to its structure and dipole than how its enantiomer would.

Immigration will help (and Canadians begrudgingly like this solution because it also shores up the income-tax “hole” caused by low a birthrate/large retired population and generous social benefits to pay for) but it can’t fix the problem because it ultimately comes down to capital and risk: Canadian companies must service international markets in order to generate an equivalent return on investment that rivals U.S. companies in order for investors to be able to deploy capital at the same volume. If successful, it ends up looking more like “an outsized proportion of FAANG-sized companies are Canadian”, and less like “Canada has an equivalent company for every FAANG but each has an outsized return” because the latter is much harder to achieve, for various reasons I won’t get into.

edit: my bad, i should yave read further - the suggestion is that the location on the Earth'a surface could influence the surface chirality.

Well if you have a 'left handed' surface and a 'right handed' surface then the problem has just shifted to the molecule to the surface.

To put it another way - what drives the asymmetry of the surfaces?
Wow, this is almost exactly what I was planning to do for my site. For another small project, I wrote a tiny shell script as a makeshift "bundler" (just embeds the CSS and JS inside the HTML) with the goal of also being able to serve the unbuilt files locally:

sed \
-e '/[/][/]script/r index.js' -e '/[/][/]script/d' \
-e '/ <script defer src="[.][/]index[.]js"><[/]script>/d' \
-e '/[/][*]style[*][/]/r styles.css' -e '/[/][*]style[*][/]/d' \
-e '/ <link rel="stylesheet" href="styles[.]css">/d' \
index.html

The HTML contains something like this:

<link rel="stylesheet" href="styles.css">
<style>
/*style*/
</style>

and the script just deletes the <link> tag and replaces the /style/ comment with the contents of styles.css. Definitely not my finest work but it worked well enough.
My fvwm2 setup is like that (the config line "DeskTopSize 3x3" does the trick) plus keybindings to jump the cursor a half or a whole screen so I don't usually need to touch the mouse while navigating around (focus follows mouse is essential to this).

everything I've found is either too simple or too complex.

Neither matters.

Starting matters.

If it is simple, you will complete it. Completing electronics projects is a useful habit.

If it is too complex, you will fail.

Failing is a useful habit.

Failing is what learning looks like when there isn’t a curriculum with lowered hurdles.

Shopping for a Goldilocks’ porridge is easier than failing. It is easier than easy projects. Shopping feels like work, but it’s not.

Just work. It is the simplest thing that might work.

I don't get why people say things are going to get worse before they get better. Global warming is a problem of cumulative carbon buildup - it just gets worse before it gets worse, and if you hit points that start to trigger feedback loops, then it gets worse no matter what humans do. Though I'd rather not believe it, my suspicion is that it's already much too late in the game to change the outcome.
