This is a good point. The author wanted to talk about rerere, and control merges are a great motivator for that. If he rebased the branch, then he wouldn’t be able to write about git rerere. :)

That said, rebasing a branch several times before merging back to master is something you can easily do if you’re the only person in the branch. When there are multiple people pushing to the branch, and when the branch changes are large, rebasing becomes impractical and even dangerous. You don’t want to rebase a branch while others are working in it, because it would require a force push.

I’d say rebase the branch when you can, which is usually if it’s a private branch and you’re the only person who made changes. Merge into the branch as you go if the branch is large and has multiple people. Commit the merges if you want people in the branch to do integration testing along the way. Use control merges and don’t commit them if you want to keep the branch stable and buffer the people in the branch from changes in master.

The ESA is sure making a huge deal out of this. I wonder if politics is involved.

> Hmmm. We move our satellites on average once a week and don't put out a press release to say who we maneuvered around...

Let me also throw in a recommendation to check out his other books/series, if you enjoy his style of writing (personally he's my favorite). He's remarkably good at that "powerful mental images in very few words" quality that e.g. the first Dune book in particular absolutely nails (partly because it's the first, so everything is new).
I was just going to suggest piping this into a pix2pix / CycleGAN trained on face edges for some creepy looking results.
The likely answer is that the satellite in question was out of control and they couldn't move it.

I don't know which Starlink sat this was, but the the other satellite that did dodge seems to be flying at ~300km. This is much lower than what the functional Starlink constellation is. Some of the initial launch failed to unfold their solar panels, and the batteries would have ran down by now, so they are rapidly decaying space trash.

Others are being deorbited under power but SpaceX would have no reason not to do dodge with those.
Has this ever been explored as a Fermi solution? I realize it’s probably on the wild side of speculation but...
Plug this into the deep face stuff and this will be really cool.
GDPR lawyers told me it should be deleted from backups if it is doable without breaking the integrity of the backup copy. If it could break the integrity or is technically impossible, then the company should have a list of all records to be deleted after restoring a backup and ensure that this list will be processed on each backup restore.
I dunno why ppl say it is so hard to delete social media accounts such as Facebook or Twitter. It is actually very easy to do

get an affiliate link for something like gambling or anything spammy

post it as many places possible as fast as possible

in fact, merely posting any link over and over will nuke your account, guaranteed.

within minutes or hour max Facebook or Twitter will lockout and ghost your account for good, erasing all traces of it from existence. That way your account is gone and maybe you will make some extra $ in the process too.
This high-rank user does comprehend the impact of downvotes, and I cringe when I see people advocating for their use. The lack of empathy is truly incomprehensible.
Definitely, and I'm not trying to say anything like "both sides". You absolutely need moral judgement.

All I'm saying is that it's quite easy to fall into a mental pattern where oppression becomes acceptable. Most people in Germany during WWII were not Nazis, and yet many of them happily accepted the status quo that made what happened possible.
Ok, so by which physical method do they have better telemetry?
Dang's response to a similar (but slightly more confrontational) comment from me:
https://news.ycombinator.com/item?id=19459658

While I mostly agree with what he said, I think there are some things they could do to give users more control without "gutting" threads.

1. Allow accounts to be deleted, with all of all their comments and submissions reverting to a [deleted] author.

2. If conversations require author continuity, anonymize the author per-thread to something like the Google docs anonymous usernames

3. Include a deletion request with clear guidelines for reasons why something can be deleted.

Of course they won't do these things because 1) it's only two people and these features will require development and maintenance 2) an opaque and uncertain process ensures that they'll only receive requests in the most necessary cases 3) people might think more about what they write if they can't easily take it back

What they could really do is add a warning to the account creation, submission and comment forms telling users that their submissions are not retractable past the grace period.
>ESA noted that it performed 28 collision avoidance maneuvers in 2018, but it was mostly to avoid dead satellites or bits of space debris. Maneuvers to avoid active satellites were “very rare”, they said, but the arrival of mega constellations like Starlink raises concerns that many more such maneuvers will be needed in future.

>“What I want is an organized way of doing space traffic. It must be clear when you have such a situation who has to react. And of course automating the system. It cannot be when we have 10,000 satellites in space that there are operators writing the email what to do. This is not how I imagine modern spaceflight.”

SpaceX simply saying it would "not act" is negligent, and I really hope there was more to it that the author just wasn't privy to. If they had better sensors and knew there'd be no collision, say so. If they couldn't maneuver, say so. Otherwise it's just a game of space chicken, risking not only those two sats but all of LEO.
Datacenter usage seems to be increasing in importance faster than PC, too. AMD’s edge here bodes really well for their future.
I'm skeptical of architectural preservationism but I don't think the "Most Beautiful McDonalds In America" really helped his case, because I can't imagine anyone preferring a standard McDonalds to the retrofit Georgian Mansion he's singled out.
It might even be the XY problem, but even if it is. Answer their question, and explain why maybe they should be considering something else after you answered the question.

At that point, one is being extra helpful by adding context. Which is in stark contrast to 'that is probably the wrong question, and here is why'. Which is hard to distinguish from being willfully obtuse.
What I would like is a paid plan where you pay for each day where you don't exercise. See "loss aversion" on Wikipedia for why.
"just like autonomous cars, if both make an evasive maneuver they might cancel each other out"

I think that's a phenomenon much older than autonomous car theory.

In addition:

> the satellites, each weighing 227 kilograms, are “capable of tracking on-orbit debris and autonomously avoiding collision.” But for this incident, this system does not seem to have been used for some reason

"does not seem to have been used" - if SpaceX made no statement we can't really tell? Maybe they were confident that their collision avoidance would simply work.
Refuse does imply a certain level of impoliteness or malice. The article only states that spaceX said they wouldn’t be taking any action and later states

> Krag suspected it could be something to do with SpaceX’s electric propulsion system, which “maybe is not reacting so fast” as the chemical propulsion on board Aeolus.

Not acting because you don’t have choice doesn’t count as refusing.

Which is the OP's point, that they shouldn't be locked.
I don't think you can hold multiple mutable non-overlapping slices though, which this would appear to allow.

Edit: I see you're talking about pony, not the op. It would seem your comment is correct. Although, pony seems to have a slightly different perspective on it.
The article clearly states that the SpaceX satellite was at this position because they were deorbiting it under power.
Now it’s true the article used refused, but it does not actually back that up. ESA does not have the authority to tell satellite operateors to do something.

“we informed SpaceX” They where informed of a 1/1,000 risk and declined to take action. Refused implies someone was telling them to do something rather than notifying them of the situation.

If your team is rebasing already public history, then you’re right. Is that what you’re talking about? History should be cleaned up locally before pushing elsewhere. Once pushed, history shouldn’t be rewritten except in emergencies, and even then it should be discussed and communicated and everyone should agree a rewrite is better than more pushes to fix the problem. A case where a rewrite is preferable is when someone accidentally checks security keys into git, for example.

Rebasing before pushing should be embraced, are you sure that’s not the majority of what’s happening?
That's fine, but then share that data and there'd be no need to waste delta-v for either satellite.

Also these aren't military assets, their specs and locations aren't secret, so if they have better tracking, they should be sharing that.
This is all very off-topic, but if it clarifies: libertarian-conservatives (the kind this publication caters to) prefer local control over centralized control, and also prefer less regulation to more regulation. So a libertarian-conservative would rather Arizona control beautician licensing standards than the federal government, but would also prefer the abolition of beautician licensing altogether. It's a coherent world view.

I think the issue is that people have some vague affinity for the way space travel was depicted in old science fiction, where you could blast off and manually control everything with possibly the assistance of a slide rule.

And it's slightly discomfiting to realize that just traffic control is so complex that it needs modern computers to track and react. Space is supposed to be vast and empty! And it is, but not in LEO.
> "It is very rare to perform collision avoidance manoeuvres with active satellites. The vast majority of ESA avoidance manoeuvres are the result of dead satellites or fragments from previous collisions."

Basically they think SpaceX is driving recklessly, which is why they put out the press release; they don't do it when they dodge dead satellites.
Wait, so you mean Dorian won’t hit Alabama!?
There was a post on HN yesterday thanking the operators for never updating the site. While I mostly agree with that sentiment, this code formatting BS is an outlier and very much needs to be addressed. Either take the feature away altogether, or just make it work well on mobile. But this middle ground where HN visitors inadvertently ruin their contributions for mobile users is bad.

I like the article but I disagree: Mappable is the correct name in this case and does transmit the meaning which is contained in the "grammatical" expansion. The confusion here is that there are prerequisites to knowing what Mappable means. One should know what map, the more primitive concept, means first. This is how derivational morphemes work. The productive suffixes still remaining in the English language such as "-able" do in fact have meanings, as do verbs such as "map", and they combine to form new meanings.

Furthermore, a bunch of things being named terribly doesn't support the thesis that names don't transmit meaning. It supports the thesis that a bunch of people failed to communicate and they should have put much more effort into naming things accurately.

> Names don’t make them any easier or harder to understand

If we renamed every variable in Firefox, for example, with numbers, people would find it more difficult to understand, so this is an absurd thing to say. The reason we use names is because they do convey meaning. That meaning (index into our conceptual map) is what differentiates them from the numerical value of the string of letters which make up their textual representations and makes them so much easier to remember and understand contextually!
That's what flagging is for. Why don't people flag more?
The ESA satellite had been on that orbit 9 months before the Spacelink satellite.
I love this quote by Sully after the incident:

"One way of looking at this might be that, for 42 years, I've been making small regular deposits in this bank of experience: education and training," said US Airways Capt. Chesley "Sully" Sullenberger. "And on January 15, the balance was sufficient so that I could make a very large withdrawal."

Absolute legend.
> Names can’t transmit meaning

Sure, if you completely ignore context. However, context is very important and is what we use to get meaning from a name.

Read this name: Donald Trump

Does it not have meaning?
gps (NORAD is using radar)
Naming is hard because communicating is hard: you have to build a mental model in the mind of the future programmer that’s useful enough to allow them to work on the project and get stuff done reasonably quickly and not accidentally break something due to a misunderstanding.

I see a lot of people struggle with naming because they’re trying to materialise the ‘right’ name, when all you really need is one that’s good enough, unlikely to be misinterpreted, easy to find/look up docs, etc.
I notice that the flight instructor disobeys the captain, who says to says to remove power from the engines, and does the opposite right as they're touching down.

Was there ever any thought as to whether that contributed to the loss of life?
> and declined for reasons the author is unaware of.

This is such an incomplete report, it reminds me of the old adage
"A lie can get halfway around the world before the truth can put it's pants on."

A proper, less sensational reporter would have waited until they knew why they declined to move the satellite before writing the piece.
There was a lawsuit about the publication of this book a few weeks ago. The Dutch intelligence service had redacted parts of it, if which they said it endangered lives. The journalist thought they redacted too much, the court disagreed. So I think the info that is left is relatively safe.

Something very important with reading news: you have to understand reported speech.

If you see "a spokesman for the president says the moon is made of green cheese", and that spokesman did actually say that, that passes a fact check.

The fact that the moon is not made of green cheese is not considered to be in the remit of journalism.
HN is (intentionally?) a very manual and obscure operation.
- most popular orbits are also most crowded and dangerous ones, there's only so much you can do to reduce the probability of collision

- there are also uncontrolled debris, non-tracked objects, military satellites with unpublished orbits etc

- just like with automating road vehicle traffic, it would require very high degree of centralization, which is never going to happen due to various reasons

- the propellant is limited so you also want to reduce the amount of avoidance maneuvers to a minimum

So no, statistical models (which you probably mean by AI) won't improve the situation much. What matters is:

- increasing the orbit determination accuracy and coverage with better instruments and commercial tracking networks; NORAD TLEs alone are not precise enough for reliable collision prediction

- better space weather prediction

- improving the coordination between the operators

- deployable decelerators for dead satellites in lower orbits, also possibly debris removal if the problem becomes really serious

i.e. stuff most operators already do, except for the debris removal
Definitely GPS, probably star trackers too. Not a good idea to have a single point of failure on position knowledge when your whole scheme depends on putting small beams in the right places.
I joined Stack Overflow on day 1 and I've found it very useful. You could argue that despite its flaws it has successfully achieved its goals. Stack Overflow is a great example of gamification.

The reason for fatigue is not because of downvotes, but because it is no longer "fun". It's done. There is nothing left to add unless you want to jump on new technologies.

Well, it counts as refusing, but it doesn't have the same connotation as when you omit context.

> If non-English languages are also considered, are there any where naming things is easier? Have to keep in mind that a "good" name maintains a balance between descriptiveness and brevity.

As a native English speaker with a relatively very weak understanding of Chinese, I find Chinese names to be generally understandable and English names to be completely opaque.

This is most pronounced when dealing with technical topics:

For example, because I know essentially no Latin or Greek, a name like "Bilirubin" means absolutely nothing to me. Whereas the Chinese word, 膽紅素 (膽 - gall bladder, 紅 - red, 素 - essence), is actually something I can break down and have any idea at all what it is.

Japanese is also generally better than English in this regard in my experience, but unfortunately it often borrows words from other languages. In this case, ビリルビン (birirubin), so it can be even more opaque than English.

In the case of "functor", I also find the Chinese (函子) more obvious than the Japanese (関手) or English.

GPS appears to not give great online performance in LEO[1], and transponders is just slightly easier radar, not a fundamental difference.

Do they have really good star trackers on their sats?

Why are they deorbiting? Didn't they just launch these?
All the people here trying to throw CBP under the bus, did you read their report?

If I have a 'terroristic' picture on my phone and I try to cross a border, and at the same time I tell CBP that I want to work in my cousin's gas station so that he will be freed up to do other things, it is reasonable to think that CBP might exercise their right to decline to admit me.

Commenters who are saying that CBP are lying: if its he said / she said, I am going to believe the person without the dead baby image on their phone. Not the person with the 5 year visa who wants to be away from their wife and child for three months for 'vacation'.

It seems a bit weak to me to call CBP liars absent any evidence (and here there is none) that they have lied.

Mainly what I want to say is about the dead baby image: if my 'friend' sends me that photo, we are having a talk stat about good judgement, he is not sending me any more photos, I am probably blocking him, and that photo is getting deleted.

And if I have that photo on my phone and I choose to tell some bullshit story about child safety PSAs etc, and about my cousin's gas station, I have to expect that discretionary decisions are not going to go well for me.
