🇸🇻 Bitcoin Law Passed in El Salvador
On June 9, 2021, El Salvador's parliament voted to adopt #Bitcoin as legal tender in the country.
"The Bitcoin Law" was passed by the Legislative Assembly of El Salvador, giving #bitcoin the status of legal tender within El Salvador after 7 September that year.

🔔 Moskva hlásí překročení hranic Dněpropetrovské oblasti, mluví o nárazníkové zóně:
Ruská vojska postupují v ukrajinské Dněpropetrovské oblasti, informovalo podle agentury TASS ministerstvo obrany v Moskvě. O překročení administrativní hranice tohoto regionu na východ od centrální Ukrajiny informovala Moskva v neděli, ukrajinská strana to však popírá. Podle Kremlu je tato ofenziva součástí plánu na vytvoření nárazníkové zóny na Ukrajině.

### 思考过程:
好的,用户现在问的是铜矿和金矿是否常常伴生。首先,我需要确认这个问题的准确性。根据我的知识,确实有些矿床中铜和金会一起出现,比如斑岩型铜矿通常含有金。不过,我得仔细回想具体的地质情况,避免给出错误信息。
接下来,用户提到他们生活在Nostr社交平台,所以可能需要简洁且技术性的回答,但也要保持易懂。需要涵盖伴生的原因,比如地质形成过程,以及实际例子,如斑岩型、块状硫化物矿床等。同时,要说明并非所有铜矿都有金,反之亦然,避免绝对化。
还要注意用户之前的问题是用中文提问的,所以回答必须用中文,并且保持专业但不晦涩。需要检查是否有上下文需要参考,用户之前只问过这个问题,所以不需要回溯之前的对话。但如果有重复问题,需要指出,不过这里没有。
最后,确保不编造信息。如果不确定某些细节,应该明确说明。不过关于铜金伴生这点,我比较确定,可以详细解释,同时提到不同矿床类型的情况差异,这样用户能全面理解。还要注意结构清晰,分点回答可能更好,但用户要求避免使用Markdown,所以用自然分段。
----------
### 正式回答:
是的,铜矿和金矿在许多地质环境中确实存在伴生现象,但并非所有铜矿或金矿都会共存。这种伴生关系主要与特定类型的矿床形成过程有关,以下是关键点解析:
1. **典型伴生矿床类型**
- **斑岩型铜矿(Porphyry Copper Deposits)**:全球最重要的铜金共生矿床类型。这类矿床形成于板块俯冲带的岩浆热液系统中,铜和金常以低品位广泛分布于石英-硫化物脉中(如智利的埃尔特尼恩特矿)。
- **火山成因块状硫化物矿床(VMS)**:常伴生铜、锌、铅与金(如加拿大基德溪矿床),金含量可达经济开采价值。
- **斑岩型金铜矿**:部分矿床以金为主、铜为辅(如印度尼西亚的格拉斯伯格矿),或铜金比例相近。
2. **伴生机制**
铜和金的地球化学性质差异较大(铜为亲硫元素,金为亲铁/亲硫元素),但在高温热液体系中,两者可通过硫化物络合物(如HS⁻、S²⁻)共同迁移,并在压力骤降、温度下降或与围岩反应时共沉淀。
3. **分布规律**
- 约20%-30%的斑岩型铜矿具有可观的金含量(>0.2g/t)。
- 中国胶东半岛的焦家金矿带即为典型的铜金共生构造环境。
- 但独立铜矿(如沉积型铜矿)或独立金矿(如卡林型金矿)可能完全不含对方元素。
4. **经济意义**
铜金伴生矿的选冶需综合考虑回收率:例如斑岩矿石中金常赋存于黄铜矿晶格内,需细磨后氰化浸出;而部分VMS矿床中金可随铜锌矿物同步浮选回收。
若需进一步探讨具体矿床案例或开采技术细节,请随时告知!

### 思考过程:
好的,用户问铜矿和金矿是否伴生。首先,我需要确认“伴生”的定义,通常指在地质过程中两种或多种矿物共同形成并存在于同一矿床中。
接下来,回想地质学知识,铜和金确实可能出现在同一矿床中。例如,斑岩型铜矿常伴有金、银等金属。此外,热液矿床也可能同时含有铜和金。
需要具体例子来支持,比如智利的某些大型铜矿含有金,或者中国的一些矿区。同时,要注意伴生的程度,有些矿床中金含量可能很低,作为副产品开采。
还要考虑不同矿床类型,如块状硫化物矿床(VMS)也可能含有铜和金。需要指出伴生的普遍性,但也要说明并非所有铜矿都有金,反之亦然。
最后,确保回答准确,不夸大伴生的可能性,同时提供实际案例和矿床类型,帮助用户全面理解。
----------
### 正式回答:
是的,铜矿和金矿在部分地质条件下会伴生,但并非所有铜矿或金矿都必然伴生。以下是具体分析:
### 1. **伴生的地质背景**
- **斑岩型铜矿床**:这是最常见的铜矿类型之一,常伴生金、银、钼等金属。例如,智利的埃尔特尼恩特(El Teniente)和中国的德兴铜矿均属于此类,其中金含量虽低(通常0.1-1g/t),但因矿体规模巨大,仍可作为副产品回收。
- **热液脉型矿床**:在高温热液作用下,铜与金可能共同沉淀。例如,澳大利亚卡尔古利(Kalgoorlie)的金矿中伴生铜。
- **火山成因块状硫化物矿床(VMS)**:这类矿床以铜、锌为主,但常含少量金、银。例如加拿大苏德伯里地区的部分矿床。
### 2. **伴生程度差异**
- **主矿与副矿**:在斑岩铜矿中,金通常作为副产品开采;而在某些金矿(如斑岩型金矿)中,铜可能作为次要金属。
- **品位差异**:伴生金属的品位可能远低于主矿种。例如,某铜矿中金含量可能仅为0.2g/t,但若矿体巨大,仍具经济价值。
### 3. **典型伴生矿区案例**
- **巴布亚新几内亚的卢希尔山(Lihir)金矿**:主要为金矿,但伴生铜、银。
- **秘鲁的夸霍内(Cuajone)铜矿**:伴生金、银、钼。
- **中国江西城门山铜矿**:属斑岩-沉积过渡型,伴生金、银、硫。
### 4. **独立矿床的普遍性**
- **独立金矿**:如南非兰德金矿、美国内华达州卡林型金矿,几乎不含铜。
- **独立铜矿**:如刚果(金)的科卢韦齐铜矿(沉积型),以铜为主,金含量极低。
### 5. **工业意义**
- **经济回收**:伴生金属是否可回收取决于品位、选冶技术及市场价格。例如,铜矿中金含量需达到约0.2g/t才具回收价值。
- **环保考量**:伴生金属的提取可能增加氰化物使用量,需注意环境风险。
### 结论
铜矿与金矿的伴生关系取决于具体地质条件,但两者独立成矿的情况同样常见。若需进一步了解特定矿区的伴生情况,建议查阅该区域的地质勘探报告或矿业公司公告。

Song recommendations from combinators
Interleaving impure actions with pure functions. Not really functional programming.
This article is part of a larger article series about
alternative ways to design with functional programming, particularly when faced with massive data loads. In the previous few articles, you saw
functional architecture at its apparent limit. With sufficiently large data sizes, the
Impureim Sandwich pattern starts to buckle. That's really not an indictment of that pattern; only an observation that no design pattern applies universally.
In this and the next few articles, we'll instead look at a more pragmatic option. In this article I'll discuss the general idea, and follow up in other articles with examples in three different languages.
In this overall article series, I'm using https://tyrrrz.me/
as an outset for the code example. Previous articles in this article series have already covered the basics, but the gist of it is a song recommendation service that uses past play information ('scrobbles') to suggest new songs to a user.
Separating pure functions from impure composition
#
In the original article, Oleksii Holub suggests a way to separate https://en.wikipedia.org/wiki/Pure_function
from impure actions: We may extract as much pure code from the overall algorithm as possible, but we're still left with pure functions and impure actions mixed together.
Here's my reproduction of that suggestion, with trivial modifications:
// Pure
public static IReadOnlyList
HandleOwnScrobbles(IReadOnlyCollection scrobbles) =>
scrobbles
.OrderByDescending(s => s.ScrobbleCount)
.Take(100)
.Select(s => s.Song.Id)
.ToArray();
// Pure
public static IReadOnlyList HandleOtherListeners(IReadOnlyCollection users) =>
users
.Where(u => u.TotalScrobbleCount >= 10_000)
.OrderByDescending(u => u.TotalScrobbleCount)
.Take(20)
.Select(u => u.UserName)
.ToArray();
// Pure
public static IReadOnlyList HandleOtherScrobbles(IReadOnlyCollection scrobbles) =>
scrobbles
.Where(s => s.Song.IsVerifiedArtist)
.OrderByDescending(s => s.Song.Rating)
.Take(10)
.Select(s => s.Song)
.ToArray();
// Pure
public static IReadOnlyList FinalizeRecommendations(IReadOnlyList songs) =>
songs
.OrderByDescending(s => s.Rating)
.Take(200)
.ToArray();
public async Task> GetRecommendationsAsync(string userName)
{
// Impure
var scrobbles = await _songService.GetTopScrobblesAsync(userName);
// Pure
var songIds = HandleOwnScrobbles(scrobbles);
var recommendationCandidates = new List();
foreach (var songId in songIds)
{
// Impure
var otherListeners = await _songService
.GetTopListenersAsync(songId);
// Pure
var otherUserNames = HandleOtherListeners(otherListeners);
foreach (var otherUserName in otherUserNames)
{
// Impure
var otherScrobbles = await _songService
.GetTopScrobblesAsync(otherUserName);
// Pure
var songsToRecommend = HandleOtherScrobbles(otherScrobbles);
recommendationCandidates.AddRange(songsToRecommend);
}
}
// Pure
return FinalizeRecommendations(recommendationCandidates);
}
As Oleksii Holub writes,
"However, instead of having one cohesive element to reason about, we ended up with multiple fragments, each having no meaning or value of their own. While unit testing of individual parts may have become easier, the benefit is very questionable, as it provides no confidence in the correctness of the algorithm as a whole."
I agree with that assessment, but still find it warranted to pursue the idea a little further. After all, my goal with this overall article series isn't to be prescriptive, but rather descriptive. By presenting and comparing alternatives, we become aware of more options. This, hopefully, helps us choose the 'right tool for the job'.
Triple-decker sandwich? #
If we look closer at this alternative, however, we find that we only need to deal with three impure actions. We might, then, postulate that this is an expanded sandwich - a triple-decker sandwich, if you will.
To be clear, I don't find this a reasonable argument. Even if you accept expanding the sandwich metaphor to add a pure validation step, the number of layers, and the structure of the sandwich would still be known at compile time. You may start at the impure boundary, then phase into pure validation, return to another impure step to gather data, call your 'main' pure function, and finally write the result to some kind of output. To borrow a figure from the What's a sandwich? article:
On the other hand, this isn't what the above code suggestion does. The problem with the song recommendation algorithm is that the impure actions cascade. While we start with a single impure out-of-process query, we then use the result of that to loop over, and perform n more queries. This, in fact, happens again, nested in the outer loop, so in terms of network calls, we're looking at an O(n2) algorithm.
We can actually be more precise than that, because the 'outer' queries actually limit their result sets. The first query only considers the top 100 results, so we know that GetTopListenersAsync is going to be called at most 100 times. The result of this call is again limited to the top 20, so that the inner calls to GetTopScrobblesAsync run at most 20 * 100 = 2,000 times. In all, the upper limit is 1 + 100 + 2,000 = 2,101 network calls. (Okay, so really, this is just an O(1) algorithm, although 1 ~ 2,101.)
Not that that isn't going to take a bit of time.
All that said, it's not execution time that concerns me in this context. Assume that the algorithm is already as optimal as possible, and that those 2,101 network calls are necessary. What rather concerns me here is how to organize the code in a way that's as maintainable as possible. As usual, when that's the main concern, I'll remind the reader to consider the example problem as a stand-in for a more complicated problem. Even Oleksii Holub's original code example is only some fifty-odd lines of code, which in itself hardly warrants all the hand-wringing we're currently subjecting it to.
Rather, what I'd like to address is the dynamic back-and-forth between pure function and impure action. Each of these thousands of out-of-process calls are non-deterministic. If you're tasked with maintaining or editing this algorithm, your brain will be taxed by all that unpredictable behaviour. Many subtle bugs lurk there.
The more we can pull the code towards pure functions the better, because referential transparency fits in your head.
So, to be explicit, I don't consider this kind of composition as an expanded Impureim Sandwich.
Standard combinators #
Is it possible to somehow improve, even just a little, on the above suggestion? Can we somehow make it look a little 'more functional'?
We could use some standard combinators, like monadic bind, traversals, and so on.
To be honest, for the specific song-recommendations example, the benefit is marginal at best, but doing it would still demonstrate a particular technique. We'd be able to get rid of the local mutation of recommendationCandidates, but that's about it.
Even so, refactoring to self-contained expressions makes other refactoring easier. As a counter-example, imagine that you'd like to extract the inner foreach loop in the above code example to a helper method.
private async Task CollectOtherUserTopScrobbles(
List recommendationCandidates,
IReadOnlyList otherUserNames)
{
foreach (var otherUserName in otherUserNames)
{
// Impure
var otherScrobbles = await _songService
.GetTopScrobblesAsync(otherUserName);
// Pure
var songsToRecommend = HandleOtherScrobbles(otherScrobbles);
recommendationCandidates.AddRange(songsToRecommend);
}
}
The call site would then look like this:
// Pure
var otherUserNames = HandleOtherListeners(otherListeners);
// Impure
await CollectOtherUserTopScrobbles(recommendationCandidates, otherUserNames);
In this specific example, such a refactoring isn't too difficult, but it's more complicated than it could be. Because of state mutation, we have to pass the object to be modified, in this case recommendationCandidates, along as a method argument. Here, there's only one, but if you have code where you change the state of two objects, you'd have to pass two extra parameters, and so on.
You've most likely worked in a real code base where you have tried to extract a helper method, only to discover that it's so incredibly tangled with the objects that it modifies that you need a long parameter list. What should have been a simplification is in danger of making everything worse.
On the other hand, self-contained expressions, even if, as in this case, they're non-deterministic, don't mutate state. In general, this tends to make it easier to extract subexpressions as helper methods, if only because they are less coupled to the rest of the code. They may required inputs as parameters, but at least you don't have to pass around objects to be modified.
Thus, the reason I find it worthwhile to include articles about this kind of refactoring is that, since it demonstrates how to refactor to a more expression-based style, you may be able to extrapolate to your own context. And who knows, you may encounter a context where more substantial improvements can be made by moving in this direction.
As usual in this article series, you'll see how to apply this technique in three different languages.
Song recommendations from C# combinators
Song recommendations from F# combinators
Song recommendations from Haskell combinators
All that said, it's important to underscore that I don't consider this proper functional architecture. Even the Haskell example is too non-deterministic to my tastes.
Conclusion #
Perhaps the most pragmatic approach to a problem like the song-recommendations example is to allow the impure actions and pure functions to interleave. I don't mean to insist that functional programming is the only way to make code maintainable. You can organize code according to other principles, and some of them may also leave you with a code base that can serve its mission well, now and in the future.
Another factor to take into account is the skill level of the team tasked with maintaining a code base. What are they comfortable with?
Not that I think you should settle for status quo. Progress can only be made if you push the envelop a little, but you can also come up with a code base so alien to your colleagues that they can't work with it at all.
I could easily imagine a team where the solution in the next three articles is the only style they'd be able to maintain.
