There are different kinds of programming competitions. Some are about solving relatively easy problems individually and as fast as possible, which is most of what I did. The best candidates usually can solve all the problems and time determines the winner. Others are about solving hard problems, sometimes as a team, like in a hackathon. I was talking about the former.

I also did a mock LeetCode-style evaluation, which my company made me do as a benchmark. It was a lot like the kind of competitive programming I mentioned. But I don't count it as an experience because it was not a high-stakes, stressful situation. Note that I had no say on the recruitment process, they just asked me and other employees to do the test to see what to expect from someone of our skill levels, it also included some other, more knowledge-oriented questions.
I agree with the part about complicated tariffs/tickets but not much else. Although not sure how many countries make it simple, the only one I am aware of is Switzerland which conveniently solves the problem by making everything expensive.

I use the app and bahn.de and things are generally pretty easy and just work. I haven't used paper in a while, recently once because my phone battery ran out, but that's it. Finding connections, adjusting options like transfer time, where you want to transfer, buying tickets, checking in through the app, getting notifications about changing trains, and even recently some things I never did like getting an invoice for my employer are all a breeze. It fails rarely and is in general slick. Recently I bought tickets through Hungarian railways and this was a pain in the ass.

The one annoyance I have is buying regional tickets, where you have to buy them one at a time which can be a hassle if you travel with e.g. three people and you want to buy tickets for all of them.
That mentoring gig shaped my python-essentials-course - about 4-7 sessions, with them homework exercises - which i have been teaching to various people since then (about ~80ppl so far, in maybe 15 points in time). Only 2-3 times did i manage to sell it and get some money. All others has been either for near-free, or within the company i have been working in - for free as well. Not even kudos from management or whatever. Once even got a warning "not to waste people's time".

You know, if someone does something anyway because s/he loves it, why pay for that? "Long term" answer is - because you want that to be available again, but IMO "long term" has fallen out-of-fashion, in software making, or even in general.

ah. have fun
whereas I use emacs exclusively in terminal mode, and would be rather upset to it no longer supported :)
Publishing and distributing first-party packages for WordPress
It's more nuanced than that.

genetic predisposition (immune/HLA genes working or not), infections (potential for antigen persistence), diet, environmental factors, stress, etc all also contribute heavily.
I do not know about Germany, but most countries have taxes on car ownership and fuel, so you need to offset those against the expenditure on roads. Road construction and maintenance also benefits other road users - transport vehicles, cyclists and pedestrians and emergency vehicles etc.

That depends on how high the orbit is. If it is high enough, the decay will take centuries.
Now? nothing.
I think this thinking is a relic of Google's status as seemingly the last remaining email provider to automatically create a Gmail account when signing up for a Google account. So using Google SSO meant using your Gmail account, and so control of the email address was nessissary for control of the Google account. If you lose the email account, you lose the Google account. This is not true anymore since you can sign up for a Google account with any email.

Whereas you can (and I believe always could*) create an apple ID with any old email address.

*Maybe this delinked situation only came about when they added the App Store to OS X, and figured they'd make less money if they require existing Mac users to get a new email account in order to buy programs in the manner which would grant them a cut.

Apple has a list of all the email addresses for its sole IDs, but it doesn't control them, and having one deleted doesn't nessisarilly affect the other.

Google and custom domain email have always been delinked from this perspective. You could create a Google account with a custom domain and then point the domain elsewhere or lose control of it, and you'd still retain conto of the account.

Basically, the required example essentially theoretical at this point - maybe it works for employers at companies that also happen to provide SSO services. So if you work at Facebook, Google, Apple, or github and have a me@FGAG.etc.com email dress, and you signed into slack through the SSO that affiliated with your company and the company email, but later don't work there and you've had your work account access revoked, you won't be able to use that SSO to sign into slack. That's what they mean by directory control or whatever.

In contrast, if you sign up to github with your work email account, unless it's a managed device managed by your work, your work doesn't actually control the account. They just vouched for your affiliation at sign up when you verified your email. So if you use a github SSO to sign up for a service that 'verifies' your work email address from github during the process, that won't change when you leave and the company revoked access to the email. Github SSO, in this case, isn't verifying you have an email account @company.com. They are verifying you once did, or at least once had, access to it. This is what they mean by the non-directory whatever.
Sounds like Token Ring...
A one week ban on the first message is clearly gatekeeping. What a bunch of jerks. A 1 hour ban would have been a lot more appropriate, and escalate from there if the person can't follow the rules.

Don't even get me started about how dumb rule 2 is, though. And rule 3 doesn't even work for normal English as many things are abbreviated, e.g. this example.

And of course, you didn't greet and wait, you just put a pleasantry in the same message. Jeez.

I'm 100% sure I'd never have gone back after that rude ban.
For the centimeterish precision needed to hover into the chopsticks, they also have the opportunity to use signals from the tower area for final alignment. I'm thinking riding a beam like aviation ILS. Just speculating but it would be easy to implement.

Optical/camera alignment is probably out of the question due to fire and smoke.
But...when I test the example, I get the right answer from 4o. Seems like they can just extend the model to identify irrelevant information over time and get the correct results more generally for similar models.
--------------------------------
Let's break it down:

Friday: Oliver picks 44 kiwis.
Saturday: Oliver picks 58 kiwis.
Sunday: He picks double the amount he picked on Friday:
44x2=88
44×2=88 kiwis.
Now, we sum all the kiwis:
44+58+88=190
Since the size of five kiwis on Sunday doesn’t affect the total count, Oliver still has:
190 kiwis.
Except for people who simply don't have 60€ a month easily, so they're left out. Also, it will absolutely not stay at 60€, it will become more expensive each year until the local tickets are cheaper again - defeating the whole purpose (if it won't be reverted outright after the next election, which the conservatives will win).

For example, in the Netherlands hospitals are starting to experiment with fasting before a surgery. During surgery arteries arteries are opened, bringing blood in contact with oxygen. With pre activated anti-oxidants damage will be minimized, helping with recovery.

Agreed, but I'm concerned that humans being humans, we'll have the entire solar system to blow ourselves over.

In The Expanse (which I highly recommend), they give a new lease on life to that quote attributed to Einstein "I know not with what weapons World War III will be fought with, but World War IV will be fought with sticks and stones" - hurling asteroids towards a planet. I really hope humanity's real future will play out in accordance with some of the more optimistic elements in The Expanse.

It's hard to say how serious you are, but this is a good example of casual notions of "luck".

Aircraft are often struck by lightning. US airlines (for example) are very safe statistically. Looking at the probabilities, I would suggest that you can optimise your actuarial projection by insisting on sitting in centre-rear position in all passenger vehicles.

From the fine article:

> Of course, we wouldn’t be here to muse on our good fortune if this chain of events had not occurred [...] But perhaps the fragility of this chain should induce some humility about our self-importance.

If we hope for humility, maybe we also need to hope for the right kind of humility. We need to understand that the metaphor of a "chain of events" implies some purposeful causation. However we came to be was an accident; where we are going depends on our ingenuity and ability to reason ourselves out of the mud and pathology.
Non native English speaker here. Been working using English only for over a decade, to the point of using my own native language to discuss technical topics (either at the conceptual/product level or at the very low level) feels non-natural and uncomfortable. I haven’t worked in software engineering using my mother tongue ever (because I’ve always been an immigrant).
In a highly developed and wealthy country it should be free.
It is difficult, but there are modeling approaches that work, such as VoF (https://en.wikipedia.org/wiki/Volume_of_fluid_method). Basically, in addition to velocity, pressure, temperature, etc., you store an additional scalar in each cell of your computational mesh representing the liquid's volume fraction. Then, you solve an additional equation to transport that scalar.

It sounds like you "tried Node" but didn't learn/read enough to understand the event loop architecture (and why node is asynchronous). Node is pretty simple (and powerful) but yes if you don't know about the event loop, you'll make a blocking call (synchronous function) and end up blocking the loop (which will hang your whole process).
true but don't forget this is test flight #5

So funny that they had a little buoy water ready to film the explosion. I want to see the views of that camera from the landing itself.
I think some Kerbel Space Program players have attempted to approximate the liquid sloshing as an inverted single or double pendulum problem inside the rocket that the control algorithm has to take into consideration in addition to the primary control of the rocket.
Thanks for the links Im glad there are people who are experts at character design.
For my untrained eyes it just looks like all of the characters are muddy coloured ( washed out greens brown etc ) AND they are pretty much all incredibly ugly. I think I saw one that atleast looked fashionable, the black sniper female.

The older I get the more concerned I get that the larger the team that makes decisions the worse the decisions are, whats the word for this? Is there any escape? Teamfortress 2, took years and teams to build, but it was just perfect.

I heard they had a flat structure which is even more confusing as to how they attained such an excellent product.
The hebron massacre happened 12 years after the Balfour Declaration so at that point the Palestinians were already fully aware that they were being colonized and they had also experienced discrimination and violence at the hands of the british and the zionists. Just describing this violence with "both sides" is erasing so much colonial history and justified resistance by Palestinians who had every right to oppose the colonization they saw unfolding right before their eyes.

Honestly, I heard about CS 2.0 from you. And you are right what you just said about GO.
Great suggestion. On it
Here's some thoughts that applies weights to some of the items on your list.

- NOTAMS and flight restrictions should be automatically ingested.

- FAA restrictions are different for emergency services.

- You should have multiple drones in your fleet to deal with low battery problems.

- Collision detection is a hard problem and part of why Skydio got so much money.

- One point I don't see on your list is dock. IMO a dock is essential to play in the fully automated drone flight space, regardless if you're talking about site inspection or first responders.
Its not the medical professionals making these decisions. That's like soldiers choose what tanks they drive. They don't. These decisions are made by the hospital/insurance company "complex"
I don't think we have a number for it yet. But it will definitely be the cheapest launch system at the time of launch.

People say 200$/kg just with booster reuse, and 20$/kg with full reuse. Of course this might be too optimistic, but I truly believe we might reach under 50$ in this decade.
no it won’t, it’ll just make it more niche than it already is.
Now we have no excuses
It's not "super realistic" because no one would never cal you from Google, or provide any customer support in the first place.
As one of the core developers, I would say "stubbornly sticking to their interpretation" is not entirely fair. I am open to changing this, but I don't want to do it hastily --- because that means changing things twice. Figuring out all the correct behaviours, in particular with equations and inline objects, is challenging. I tried to constructively present some arguments in favor and against the proposed changes in the linked issue, but I simply did not have time to push things forward beyond that myself so far.
> you’re spamming a reply

They’re still going [1] and it appears to be a common thread across their recent commenting.

But they’re getting flagged, so no need to continue. (EDIT: It’s still getting traction.) It’s a tempting (and in my opinion mean-spiritedly preyful) conspiracy theory on an ephemeral topic. I always appreciate folks with domain experience similarly flagging nonsense in other threads.

Having enough lift capacity to take a shot at putting a pair of telescopes out far enough to exploit solar gravitational lensing to resolve exo-planet surfaces would be a hell of a thing. Orbital refueling would mean we could reasonably build something big enough to be able to boost out that far (would still take decades to arrive).
The whoop measures and averages your HRV over your deep sleep to give you one number.

The AppleWatch, at last time I researched, just gives you your HRV, NOW. And my impression is it's not really a useful number as a snapshot, since it varies so much during the day it's not really useful to know what it is at 10:40 AM EST.
Wait, so you're just not eating every other day?
It isn't. I do most of my programming in Prolog, I write oodles of it daily, and it's not a problem. You learn to think that way easily.

The argument is basically that Prolog is not 100% declarative and that if we jump through a few hoops, and translate it all to functional notation, we can make it "more declarative". But let's instead compare the incomplete declarativeness of Prolog to a fully-imperative, zero-declarative language like Python or C#. We'll find I believe that most programmers are perfectly fine programming completely non-declaratively and don't have any trouble writing very complex programs in it, and that "OMG my language is not purely declarative" is the least of their problems. I hear some old, wizened nerds even manage to program in C where you actually can drop to the hardware level and push bits around registers entirely by hand O.o

I don't know which of the several typists plugins are you talking about, but they all seem decent, but years from achieving the features auctex has.

Just to say, the most important features:

Well, the feature you mentioned of clicking the PDF and redirecting to the source.

Preview in the same buffer (window) as the code

It uses other regexps to recognize the enabled packages, and then adds the package's macros and environments to its list, so with a command you can open an environment or macro, and it recognizes which packages you are using, if you are in a math environment, etc. and shows only the ones you can use in the context. It's like a super-intelligent set of macros.

AucTex has also great support for bibtex/biblatex, and glossary/glossaries, both for using the macros and for compiling.

Automatic, intelligent, labeling.

And a lot more (altough this is probably the biggest latex package, there are a lot of other smaller packages that are also extremely useful) . Maybe it's not the hardest package to do, but it needs a lot of people and time to replicate, basically what typst is also lacking, for now.

Of course, that means you could also fit a James Webb-folded telescope except make it a lot bigger :-)

Isn’t this a forum of hackers caring about the news? Everyone seems excited here and that excitement naturally leads into curiosity for many who identify as hackers.
IIRC, above something like geostationary they tend to decay upwards? Though the old orbital ring white paper wasn't suggesting anything like that, this was an alternative to needing to go so high in the first place.

I've gotten answers from OpenAI that were technically correct but quite horrible in the longer term. I've gotten the same kinds of answers on Stack Overflow, but there other people are eager to add the necessary feedback. I got the same feedback from an LLM but only because in that case I knew enough to ask for it.

Maybe we can get this multi-headed advantage back from LLMs by applying a team of divergent AIs to the same problem. I've had other occasions when OpenAI gave me crap that Claude corrected, and visa versa.
> SNCF-Connects lets you specify the exact seat configuration. You can choose single, double (window or not), quadruple (next to each other or face-to-face). In addition to that you can express your preference for family area and if you do not want to sit facing against the driving direction.

You can do all that in the DB app. You can manually select which seats you want or just say the types of seats you want (e.g. compartment or open area, isle or window, table or no table, quiet area or not, family area etc).
God. Yeah. I’ve always hated #IAMPolicies on Freenode :)
Well, if we could not reproduce with changes, what others have written and we have learned, it is unlikely we could make real progress. There are many more concepts, like fair use, meaningful changes, and other legalese; as well as how people use the term "plagiarize" differently. I never heard of this "self-plagarizing" concept, it seems like something fringe that would not be enforceable other than in the court of public opinion or the classroom via grades
Falcon-9 relies on GPS and a couple of altimeters. (Filtered, as others have already said, with the help of data from the inertial sensors.)

Compared to Falcon-9, Starship/Superheavy additionally has a command link from the ground. Whether it is used to coordinate the movement during the catch is not publicly known, but it is easy to imagine how this could be useful.

Because the rocket weighs a small fraction of what it did at launch, specifically because it only has 2-3% fuel left.

Fuel is the vast majority of the vehicle weight at launch, kind of like an empty vs full can of soda.
Even without the catch step, I always feel like their boosters are coming down way too fast way too late, with engines reigniting startlingly close to surface. Never ceases to surprise me.
I think you can prove Many Worlds Interpretation correct for yourself. You do the Schrödinger's cat thing on yourself. If MWI is correct, you'll observe yourself surviving indefinitely even if every second there is a 50% chance determined by a quantum event that the trap triggers and kills you. I'm not sure this would convince anyone else even if you open the door after 6 hours and come out alive, and regardless the vast, vast majority of total observers would conclude the experiment failed since in most universes you'd be dead. But you'd either know the theory is true or just be dead. Not really worth the risk but I think it is testable.
