What do I need to do to get my systems of linear equations to align at each of the addition/subtraction/equals signs without manually adding silly things like \phantom{2} in front of variables with coefficient 1?

@JosephWright @martinscharrer @stefankottwitz Hey guys. Would you mind taking a look at this meta question and weighing in with your opinion? (Anyone else is welcome to contribute as well, of course.) Thanks!
@JosephWright So it should be answered for the sake of answering? I think that the reason it's been left open is that no-one wants to make a decision, and that's a good thing. If anyone felt really strongly, they'd say so. I suspect that if we're pushed, we'll say "No, not on topic". But if we're not pushed then it'll be okay to post the occasional such question but don't expect a great response.
@PauloCereda Noo, its the so called ker ning, which is the sound you get when you drop the composing stick and the little typlets go "ker ning" all over the floor of the print shop.
@StefanKottwitz I really feel that that is an answer for the sake of answering! If I weren't busy with other things, I'd do my best to think of a meta question that couldn't be answered and post it. Unanswered questions are absolutely fine on meta. The SE team seem to have a severe case of "If it's hosted on a Q&A site then it must be either a Question or an Answer" which just doesn't work for meta!
@AndrewStacey I did not just want to fill the space. This specific topic is not covered by the faq, so we can use this as a reference case.
@AndrewStacey Regarding answering in meta: I agree that {discussion} questions might naturally be without an answer, however I expect that every {support} tagged question deserves an answer.
That question was tagged {discussion} though, no support required.
@StefanKottwitz Except that by answering - and as a moderator - you have effectively written the rule on this one. I hadn't answered, for example, because I wasn't sure what we ought to say on this. I guess I was waiting to see if anyone had a definite opinion to which I could react. I would not like to see this used as a reference case, and unanswered then there was no danger of such, but now it could become policy de facto instead of de jure.
@AndrewStacey It's still tagged {discussion} and you could contribute to the discussion, similar to what you say here in the chat for example. Even users who don't write answers, could show consent or not by voting.
I just did not write "I think", "perhaps", "maybe", I directly wrote my point of view and the question is still open. Yet, after two weeks, nobody said or commented anything about that it might be offtopic.
@AndrewStacey "I guess I was waiting to see if anyone had a definite opinion to which I could react." Now you can ;-)
In unclear topics, it could even be good to post a pro and a con answer, with reasons. So users can vote on it. Better than intentionally leaving it unanswered without giving chance for voting.
@StefanKottwitz As a moderator, it's more important that you use words like "I think" and "perhaps" since when you don't use them, your statements can be taken as definitive by those who aren't so ... rebellious as me! The fact that no-one answered it after two weeks is very significant. It says two things: "The answer isn't obvious" and "No-one has a particularly strong opinion". That says "Posting such a question could be considered an experiment" suggesting: ...
... give it a go but don't be upset if it turns out people don't like it when they see it.
Experiments like that are a very good way of deciding what is on and off topic, much better than theoreticals. It's often not until I actually see something happening that I decide whether or not I approve of it - particularly borderline stuff like this.
@StefanKottwitz Thanks, that's better. I know I'm being a bit jumpy on this - I think it's partly because this seemed to be started by an SE Grand Initiative and they always get me on the defensive.
@AndrewStacey I understand your concern, but in the main we have not really had a problem with the Powers That Be. They are usually trying to be genuinely helpful.
@JosephWright Having watched Math-SX from afar, I'm not quite so laid back. I still think that SE doesn't really get academics - despite Joel's description of the SE network as being like a university - I agree with him on that vision, but I don't yet see that he realises exactly what that means. However, I agree that SE are usually trying to be genuinely helpful - just that they don't always go about it in the best way.
@JosephWright Remember also that I have seen the moderator chat room .. and that I didn't much care for what I saw there. I do realise that other sites are harder work than TeX - but that's my point! Having a one-size-fits-all policy is doomed to failure with so much variety, and basing it on the worst cases just compounds the problem.
@AndrewStacey Don't worry, I remember :-) We really are left alone most of the time, and I don't think we need to worry too much about the very occasional question/suggestion from the HQ
@DavidCarlisle LOL. Although I learnt from Kopka & Daly, I found the original Companion very useful to fill in the gaps. The new one is twice the size - an excellent metric for a vade-mecum. But even though I called it a vade-mecum, I'm going to read it cover-to-cover. Sure beats Wittgenstein!
@PauloCereda I never really understood that. When I lived in Rio, I used to buy stuff from Amazon, and it usually arrived fairly quickly...
So if this site is anything to go by, it looks like there should be another installment in the series with tikz, has tikz really taken over the TeX universe or is it just a feature of this site (never heard of it until the other day, but I've been off in MathML land for a while...)
@DavidCarlisle It's for graphics in TeX, it doesn't compete regarding text typesetting. Since it's implemented and used in TeX, it belongs to this site, even if it introduces additional syntax.
There may be some reasons why there are many question on this site. For example, a lot of LaTeX questions have been answered on the Internet for many, many years - TikZ question might often be fresh.
And TikZ is great but a new and perhaps difficult concept when it comes to advanced subjects.
@FrankMittelbach I ordered it from a bookstore. Unfortunately, most of these books aren't in their local stock, so they had to import. Maybe that's why it took so long. :(
@BrentLongborough Ah Amazon is great for those purchases. :) I need to get myself an international credit card.
@PauloCereda Oh, yes, I see. Sorry for my unjustified assumptions (:-) I didn't realise that some Brazilian cards had restrictions (the one I used was with Banorte).
@PatrickGundlach Am I right in thinking that ß (that's Alt-s on my keyboard) currently becomes SS when in upper-case? So are they trying to write IMSSIS or IMBIS?
When translating the TeX Live messages, I had to translate "idea" (EN) to "idéia" (PT-BR), but the new norm tells me to use "ideia" instead. I used the old spelling! Viva la resistance! :P
By the way @BrentLongborough: They are trying to write IMBIS. And as far as I know, the eszet (ß) is no longer used in German. I think they just write ss now.
@egreg (and others) you just edited an answer of mine (tex.stackexchange.com/questions/43983/…) and I am not sure what you changed. Do all brackets [] need to be escaped in a code block?
@egreg thank you. I now see. Somehow in the cut/paste I "escaped" the brackets which is wrong. I am not sure how that happened, but I will watch out for it.
@egreg Well, it wasn't until I had answered it that I realized there was this other question... To me, tex.stackexchange.com/questions/14620/… seems more general, this is why I would keep it (I could move my answer there).
@MarcoDaniel Yes, of course. I'm open to suggestions for a good syntax for "generalized continued fractions" where the numerators can be different from 1.
I think that updating these converters would help TeX stay relevant as a document processing language. In these last few years, web development has really skyrocketed. CSS3 has brought along a lot of support for rich typography on the web as well as hyphenation using TeX algorithms. There are als...
@PauloCereda Actually, for a mindmap we could use some nodes with styles and connect by edges, if with TikZ or PSTricks, but the mindmap library is a fancy start :-)
@egreg Oh, that question. :) I was so close to find a solution, but the only thing I got it working was the replacement of those texts. I wasn't able to get different stuff for the heading and footer bars, and even get the names for the previous and next sections. :(
@AlanMunn Also, the Onion maybe doesn't get the subtle difference between smart and clever: Einstein wasn't smart enough to invent W*rd, but he wasn't clever enough to invent TeX.
@wh1t3 I've never really understood why mindmaps have to be trees, when ideas can actually loop back and meet up somewhere strange and (sometimes) exciting?
Since your question hasn't been answered I decided to provide a pointer. Mark Wibrow recently provided a solution in comp.text.tex for a ``blurred'' node shape. It seems related, so you may want to have a look.
If you need an answer to your question, then you may also consider asking it at comp....
@BrentLongborough that's why I meant, you could place some nodes anywhere (perhaps define some fancy shapes for different purposes), then connect by (straight or bent ) edges arbitrarily
@StefanKottwitz with all due respect .. please use the right tool for the right purpose. The purpose of a mindmap is to fast map your mind. that either requires paper and pen or one of the really good and fast mindmapping tools but not a structural language describing the relationships. And personally I think it is going overboard if you after the fact want to "recreate" a mindmap in some TeX language just to have it in the same source.
@wh1t3 and no mindmap either
@BrentLongborough because the human mind can't deal with more than 5-7 things in one go and the classical mindmap trees just work very well. And don't forget that there are second order links possible (and useful)
@BrentLongborough right, it does work or it doesn't; depends on the way your mind works I guess ;-) For me they are really useful tools .. I even given a bunch of talks straight from a mindmap. But the keep is that it is a quick way of organizing your thoughts (if you know the technique or have the right tool) ... which is why I question the idea to do this in TeX. and if you start from a gui .. i would just export a jpg and be done with it ;-)
@PauloCereda that makes less than 90 per day - easier to do than reading 50+ pages of TLC2 per day I guess ;-) which is what @Brent set out to do (or so he claimed :-)
@FrankMittelbach TikZ wasn't a strong recommendation but a mention that such a support library exists. That it's not easy to handle for not TikZ users doesn't forbid to mention it. For a TikZ friend, it's quite easy just to specify nodes and children, perhaps an angle and color option. The fancy image is a complex construction, but this shows easy mapping: texample.net/tikz/examples/computer-science-mindmap
And: TikZ (or LaTeX's) friends usually have LaTeX and TikZ and thus the tool already installed, no matter on which operating system, could just go ahead instead of finding, downloading or bying a tool
Once somebody works with mindmaps, the next and another mindmap is quickly redone, also with TikZ. Pasting math expression into the nodes, for mindmapping proof thoughts ...
well, I did not use mind maps but I like doing things within LaTeX :-)
@StefanKottwitz guess we just differ then in opinion. why should I want to "redo" a mindmap in another tool? And for me to make a mindmap directly in TeX would just mean that the purpose would be gone (to map your mind fast and easy - because even if you say it can be done quickly if you are fluent in Tikz it would never be quick enough. ... we can have a contest if you like :-)
@AndrewStacey No particular reason beyond trying to make sure meta questions (where possible) are getting responses. Obviously not everything needs a response (that'd be insane!), but for questions, even if the response is "I don't know", it's better than someone asking a question and just hearing crickets in response.
@FrankMittelbach Sometimes mindmaps are (possibly mis-)used for presenting concepts. In that case the appearance might be more important than how quick it can be freehand-drawn. And, why not to have something fancy but pretty useless :-)
I'd forgotten about that particular question: my feeling is that the suggestion may not always be best (updates can break things as well as sort them out)!
@JosephWright Makes sense to me. I read through the comments on the question and it seemed like there was overall consensus for updating the FAQ, but if not, that's cool too. You could voice your opinion on the post as well and see how it all shakes down.
@@KeksDose I'm not sure what the point of your last comment was tex.stackexchange.com/a/44099/2693 . The reasons for the list being out of date are really neither here nor there. (And since tikz-qtree is directly emulating qtree it's kind of obvious that it is for linguistics).
@PauloCereda We have a similar system. But the points are different: 10 if your speed is 60km/h over the limit; 6 if the speed exceeds the limit between 40 and 60 km/h; 3 if the excess is between 10 and 40 km/h
@henrique As I said, there's no reason to prefer a syntax {\command text} to \command{text}. Especially if the "switch" syntax poses big problems in implementing it. It's easy for simple font switching (but you have to insert manually the italic correction), not at all if you want also to process the text.
@egreg i see... i use to prefer the \command{text} syntax, but in this particular case, it seems to require the other way... The issue is actually happening whit titlesec package (I've given up abnt formatting commands and rewrote the whole titlepage)
@egreg I'll add this in the question and the example.
@PauloCereda I made some workarounds with memoir class, but had no time to get it to work right... I'm always against the clock, so I end up running back to the good old abnt.
@henrique Look for the explicit option; however the last command in the relevant argumen to \titleformat can take an argument, which is the section title.
For example, with `\DeclareRobustCommand{\smallcaps}[1]{\textls[10]{\scshape\MakeLowercase{#1}}}`, you can say \titleformat{\section} {} {\textsc{\MakeTextLowercase{\thesection}}} {1em} {\smallcaps}
There is a suggested edit where one who has an answer write that he/she couldn't understand how to post an answer and therefore tries to edit the question by adding the answer to it. How can we solve this?
Is it a good practice to call the variable a method returns with a variable name result?
For instance:
public Zorglub calculate() {
Zorglub result = [...]
[...]
return result;
}
Or should I name it by its type?
public Zorglub calculate() {
Zorglub zorglub = [...]
[...]

@egreg I actually tried that hahaha! I must have made some error somewhere, becuase it said it did not recognize the \mathtinner command... Probably just a missing bracket.

@JG Sometimes with questions for which there are no obvious answers, or that might require quite a bit of debugging on the part of answerers, adding a bounty can be a reward for that work. It's also possible to add a bounty after the fact as a reward for a really helpful answer.
@JG For most things just upvoting and accepting a helpful answer is enough. If the problem you needed solved was very important to you or you think that the answer went beyond what was needed, then you could add a bounty, but nobody would expect you to.
I answer math related questions on a norwegian website. I must say I was much more worried about postcount when I had 300, than when I now have 3k. I did not even notice when I tipped. I just answer because I like to help people, and I guess that is how most people here feel too.
@JG Here's the question that earned me my first bounty. If I recall correctly, I spent a few hours answering it, so the +250 definitely was part of my motivation.

@PauloCereda No, it's not really about English per se, as I think the same collocation is odd to say in Portuguese. It's about whether it makes sense to say that you "own" your language.
