Assuming that they will eventually have displays around the sides to show ads, they could also use those to show nearby people who they see and how they plan to maneuver around them.

So if they are showing an ad on the display on your side it means that either it doesn’t see you or thinks you are far enough away that it does not have to account for you in its short term planning.

If it sees you and is taking you into account it could show a diagram showing you and what it plans to do.

Hello! I'm Marwan, a software engineer with 4 years of experience in developing modern full-stack applications. I am the co-creator of Pennant, an open-source computational notebook designed to facilitate collaborative coding through real-time interaction and shared execution environments. I also actively contribute to the open-source community, with recent efforts focused on enhancing ZenML's MLOps framework. At ZenML, I've contributed to developing a VSCode extension to facilitate ML workflows and MLOps, and integrated a comprehensive testing framework for AWS Deployments. I'm actively seeking roles that offer technical challenges and align with my skill set.
Russia acknowledges continuing air leak from its segment of space station
It’s a shame that most comments here are debating the meaning of “10x” and rather missing the point of the article. This one spoke to me completely outside of this productivity distinction. I’m forever finding myself doing the same; trying to rationalise dev envs, the write-once CI code that nobody will touch, or fixing egregiously bad tests. The author is right; nobody will thank you for it but it’s also crucial.
Partnership as Shared Values
An Ansible playbook running on a relatively cheap hetzner box. In general bridges require you to self-host a homeserver. A federated homeserver will need 4GB of RAM at least and 8GB if you plan on joining large rooms. The playbook is controlled from a single config file and sets up all the bridges you need.

A lot of custom front end components that I’ve built were more about aesthetics than functionality, so I agree that it’s often unnecessary. In terms of functionality, you can get really far using only native HTML elements.

One common front end component that you can’t build with vanilla HTML is an autocomplete/typeahead input. I’ve had to build a few of these in JavaScript and I do think they’re genuinely helpful. It’s helpful to get suggested options as you’re typing. I also think search results that get filtered in real time as you type are helpful and can’t be accomplished with pure HTML.
> We found R has a really hard time integrating into data pipelines and was best used as a standalone tool by individuals

In my org we have several 100% R teams (including mine) that have been developing and maintaining business-critical, data-intensive applications for a decade now. We don't find R difficult to integrate into data pipelines. We write our data pipelines in R, and we find it very efficient to do so. They talk to databases, APIs, command line tools, etc without issue.

Doing what we do in Python is unimaginable, especially if pandas is the tabular lingua franca in the team. I vehemently agree with this article on the clunkiness of pandas from a sister comment: https://www.sumsar.net/blog/pandas-feels-clunky-when-coming-.... Compared to dplyr and the tidyverse, pandas very noticeably gets in your way rather than being a tool of thought. (For what it's worth, there are other teams in my org that use Python for entirely justified reasons, and they use polars these days, not pandas.)

If I had to complain about anything in R these days, it would be the increasing complexity and illegibility of error messages. Tidyverse tracebacks are often dozens or hundreds of lines. This is made much worse if you have a web app in the Shiny framework, as Shiny seems to mangle and garble what little useful information you can get (my kingdom for an error with a file name and line number). Even outside of advanced packages like Shiny, the reporting of error messages suffers from some clunkiness and irregularity.

As an expert user, I can usually squint at the error barrage and infer what is really going on, but it's probably quite confusing and off-putting to newer users.

Overall though, I'm not seeing any competition for R in our space. My fondest hope is that in the coming decades there arises a new, thoughtfully designed language with the Lispy flexibility of R, but also optional type safety and static analysis affordances. I'm not sure if that's even possible, but I hope the computer science geniuses figure out a way.

IR lasers are in fact more dangerous, for the simple reason that you can't see the beam and so you can't tell if it's on or where the beam path is.

And the most common cutting laser is the ~10um CO2 laser, for what that's worth.
The evidence from clustered orbits points towards planet nine likely being right in the middle of the busiest part of the night sky, nestled between millions of stars of the milky way. The assumption is that we already have pictures of it, it's just that when you photograph that part of the sky you are not likely to notice one very faint point of light in the middle of the ten million brighter points of light on the same plate.

In this case he appears to be correct. The article suggests 20 Indians have been "employed" by the Russian army.

It might be relevant if India gets really unhappy about it, but they might also just kick up a small diplomatic stink then move on. 20 people in India would be doing well to register as a rounding error, the Indians appear to have been benefiting greatly from the war and one of their major diplomats has been talking a lot about making sure the Russian's have diplomatic options. So maybe it is a big deal or not, it really depends on India's response before there is anything interesting to note.

It is astonishing to see something so reasonable and objective in the Telegraph which has a very strong pro-brexit stance.

I think I heard about this article on The Rest is Politics podcast this week, where they summarised it pretty well.
"There may be some element of truth in what she says about Whitehall obstinacy and the shortcomings of non elected technocrats, but her take on events is essentially just a lot of paranoid nonsense straight out of the populist playbook, where an imaginary “enemy within” is created as a hate plank to channel the discontents of voters."

I had to stop reading here, it's clearly sensationalist.
im somewhat of an armchair data scientist myself.

However - I'd love to learn your ways; specifically - what are your best recommendations for python over R?

Specifically, even though my R skills are weak - I think that RStudio is pretty darn amazing - what do you recommend over Rstudio?

I'd truly like to hear what a good toolbox looks like from your perspective these days (especially now this little GPT toddler is bonking into everything in my domain)
I've always thought that a good model or theory predicts observations (like a new particle, or an unseen planet) and is confirmed to be accurate by those observations.

A new model that is designed to fit existing observations that don't match our expectations based on the old model, without it correctly predicting new unexpected observations, seems like a rather weak proposition to me.

Buying an Android phone from a non-Google manufacturer gives much less money to Google than buying an Apple phone gives to Apple. Most here have the technical skills to follow that up by installing F-Droid and thereby avoid paying Google anything through the Play Store or ads.

Also, the mere fact that that is possible sheds some doubt on the assertion that Google is worse than Apple, at least if we're looking at the user freedoms advocated for by the top-level commenter.

DM can't explain renzo's rule, or the tully-fisher relationship, or why the milky way has a keplerian return (efe from the magellanic clouds), or why elliptical and lenticular galaxies don't seem to have dark matter. All these are explainable by MOND.

MOND also predicted early galaxies, and a group seeking to disprove MOND by disproving EFE changed their mind because they found evidence of EFE.

> it fits the data best.

It's easy to fit the data when you can conjure a parameter to explain anything. What if I told you that GR is wrong and there's a ball of dark matter orbiting the sun that distorts Mercury's orbit.

You wouldn't be able to prove me wrong.
> Because that's where it is unsafe: You can introduce a value of the same type that is outside of the enumerable range. You cannot introduce a value of a different type, though. It is type safe

C’s type system is unsound, and not all compileable programs respect its dynamic requirements. We cope with this by referring to some code as “not type safe”.

foo bar = NOT_FOO;

You say this “typedef enum {…} foo” is not a type, naming a set of values, but just a convenient alias for whatever the representation is, thus all “enum” (regardless of actual decl) name the same set, and every constructor expression shares the same “type”. Consistent with the language specification, and passes the type checker, so you could say this code is “type safe”? but it’s one hell of a foible and not consistent with any lay (non PLT) understanding of type safety, where typesafety means the type written in the code and the runtime representation won’t desync (no runtime type errors).

If you simply forbid UB and refer to only strictly conforming programs, I will accept this modified meaning of “type safe”, but grumble that this meaning is not very good

edit to encompass parent edit: as a typescript nonprogrammer, I have nothing to add :) I am confused why you are putting the features in opposition. gradual + value-sensitive typing is a good feature, but doesn’t conflict with sums. in ocaml, we support both, real sum types as well as variant [`A | `B] etc that are structural in the way you’d want C to be

Exactly, it's completely unnecessary extra information that doesn't need to appear in the core data model that the user never directly sees. Extracting credits, debits, reversals, returns, etc. is all higher-level information.
> Surely light without pauses has way more ability to send two photons one after another than light with pauses.

No it's the opposite, SHG[1] requires huge spatial energy density which also means huge temporal density (power). A continuous wave of the required power would obliterate your retina (and your head).

There is also no blink reflex unlike visible light, so you can easily stare at it for longer than you would a visible laser, meaning it would be a lot more dangerous even at the same power.

It turns out that photomultiplier tubes can also see into the infrared, even when they're not supposed to. We built a PMT-based detector that was sealed up and so we thought it'd be nice to have a camera on it. We went with an IR camera and IR illumination so we could have the camera on while the detector was running. We chose the wavelengths carefully so that the entire peak of the IR LED emitters would be in the "no response" zone of our PMTs.

Turns out that, no, you could totally tell when those LEDs were on despite that being "impossible". We didn't do any research into this because it was completely feasible to just not run the camera and the detector at the same time, so we did that. (It also wasn't hard at all to choose an IR camera in the first place, so not a lot got wasted here.) PMTs are a little different than many other light detectors (this is how they get single-photon sensitivity!) but the hypothesis of photons doubling up seems completely reasonable. Perhaps we should have placed the IR emitter wavelength at at least twice the maximum sensitive wavelength of the PMTs? But then these detectors probably would have been sensitive enough to notice triple coincidences, so who knows....

I don't think this is really relevant? The Twitter post is more about Google losing the AI race because they were too blinded by their current business and not realizing that their main business of "helping people research and find information" could be better served with a chat engine rather than a search engine. Essentially, they stopped innovating, and that cost them a ton in terms of opportunity. It doesn't mention AI ethics.
It’s worth reading further if you have a broader context of what and who is being discussed, and what newspaper is publishing this.

If you haven’t used Emacs ESS it may be hard to explain what you’re missing with a true REPL, but if you had used it in the past and add tidyverse to it, you basically have super smooth interactive editing with the ability to quickly pool text from other REPLs, past notes or scripts. Contrary to the similar Python repl, you can easily pull and edit chains of multiple commands via R’s piping.

TextAdept has been around for ages. It's a great lightweight editor.

However, it is missing a lot of features I've grown used to in (arguably more baroque) editors like Emacs, Helix and VS Code. Mostly stuff that builds on LSP.

When I last tried it (admittedly almost two years ago), it didn't have Rust syntax support at all and I couldn't get LSP (which has a plugin module made by the main developer at https://github.com/orbitalquark/textadept-lsp) to work at all.

I'd be interested to hear if anyone tried it more recently and has had a better experience.
