Love Stole the Day posted:reverse a string strictly using C and not C++ with its convenient STL back_inserter. For something like that you can pretty much just write it in 'bad c++'. Pretend you don't know about any of the c++ features, use a while loop and indexes and you've got C. (tongue in cheek but kinda sorta true)

mike12345 posted:Is "The C Programming Language"* book still the go-to reference when learning C? I did a bit of googling, and its being referenced the most. Is it didactically just that good? It's 30 years old at this point, so I'm a bit surprised there's been no other book that can rival it. Driver developers, real-time embedded systems developers, database developers, etc. all use C in different ways, and while not universal within their niche, may adopt different conventions. The age of a project can also inform the conventions adopted. Approaches that are common in one domain may be completely unacceptable in another (see JPL's C coding standard). By all means use K&R as a reference guide for the language, but I'd quickly invest more time in the application-specific literature for the problem you want to tackle in C.

What you said doesn't seem wrong, but I don't see how passing a logger via constructors would prevent that vs. a global/singleton type logger instance. Especially since it would be really easy to compose a new logger on top of the globally scoped one that does the same thing, but doesn't require you passing it "down" through a bunch of constructors. If it's not clear to anyone else I'll just move along.

Often the stack trace of the current thread doesn't actually match the context you want - consider, for example, a callback that's being run after a network request completes. In that case, your callback should really be getting it's logging scope from where it was set up, and not from whatever's in charge of running network callbacks.

That makes sense, and I'm getting flashbacks of troubleshooting RxJava where the stack traces in the logs are just miles and miles of "onNext" calls.

Hey sorry to bother you all. I'm wanting to find a program or some kind of solution for a problem I've got and I'm not sure where to post it. Am I in the right place to ask for help in this regard? If not, then: Where should I take this question? Else: I want to use my laptop as a hotspot and share a document as I'm writing it, like with onedrive or google docs, but locally over wifi, except updating at a higher speed, like every second or two, and I want them to have read-only and no saving. So essentially they would be reading over my shoulder as I generate a doc. Prob want to give them option to copy a few lines here and there but not copy the whole doc outright. If it could be something they could open in a web page or something like that, it would be great. Having my clients view it in something other than a word doc would be permissible too, like a messaging or chat screen, but with the above mentioned limiters, esp. being realtime update, read-only and BTW also being 100k words or more, with me appending text at 100-200 wpm for hours at end. And I'm working in Word on my end. I've looked at a lot of free/shareware apps and nothing looks too promising. Presently wondering if putting MS Sharepoint server on my laptop would enable this but I know nothing about sharepoint really. I'm not a programmer, but I'm not a complete idiot. Closest thing I ever do to programming is write some ahk scripts, really. Any advice would be appreciated.

I thought about it and not really, and for other reasons as well. One app I looked at that I like is RealVNC. But really it's about providing a document they can view that updates in realtime, not a screen sharing utility. I don't want them to save the doc and essentially steal my work, but I do want them to be able to navigate around in the doc on their own screen without affecting my work. ED: or search for text in it maybe, or copy a single paragraph.

If they can view the doc, then they can copy it. At the very least their OS will provide screengrab utilities that can take images of the doc. I don't really understand what you're trying to achieve here. I mean, I get what you've requested, I just don't understand why. Maybe there's some other way to accomplish your goal that we could suggest if we knew more about the problem?

Yeah, but screengrab utilities would be way too much work on their end when they can just get it through legit channels. I don't think anybody could make a way of viewing it that would be 100% secure against cheating in some fashion or another. But one thing I can do is the devices they view them from can be loaners, tablets or something, which would also limit their options on saving it. And they know they aren't supposed to usurp my work and mostly are honest. I just don't want to give them a save button or make it too easy. I do a lot of transcription and need to share my work in realtime but locally, not cloud, and so they can basically only read the doc, not make changes or save it. High speed transcription, and for sustained periods and docs that are 100 pages or more by the end of our session. One iffy idea was I was thinking maybe, just maybe if I purchase a MS Sharepoint server license and put it on my laptop I might be able to do something like that. But I have no experience with that and I bet there's an easier way. And BTW, your AV is triggering me.

So, you can either find the program that does this, hire a dev to write one for you that does only what you need (and you have control over what features it has), or adjust your expectations.

OK, reading between the lines here, you're transcribing text in near-realtime, you want people to be able to read the text, but the text itself has value that you want to be able to exploit later as well. Thing is, the immediate value you're looking to provide here is the ability to read the text as it is generated. Is there some reason you can't just charge up front for the transcription service? Then you shouldn't care what they do with the transcribed text because they've already bought it. Sorry about the avatar by the way.

I don’t have a solution for you and haven’t heard of anything like what you’re describing. What sort of user experience are you looking for for both yu and your users? You want to write in MS Word then have your updates sent to read-only user clients in near real-time. Is MS Word a hard requirement? Do users need to be able to scroll around in the document or would it be sufficient for them to look at only the part your are writing? Does it *have* to be a live-updating document or would frequent saves to msdoc files that the users periodically refresh on their own be enough? Would a user be allowed to get the doc file? Would they be allowed to view it in word (opening in word probably means they can copy paste the whole thing but your formatting will be preserved)? I could probably keep going, the requirements aren’t very clear. If you could post the other programs that do this and list their shortcomings that might be an easier way to communicate your requirements.

Somebody from my own country preferred also but not absolutely required. I doubt you will. I'm guessing it would take 1-2 weeks to get something 80% of the way there. Even if you only bill at $50/hr, and that 80% is fine, and there are no bugs or support needed - that's $2000-4000. This sounds like a project with no well-defined requirements, and no money behind it. As a developer, I would hard pass on this. As someone requesting this, I would figure out which requirements are most important: - get rid of the realtime component, and just share the doc as a PDF - get rid of the requirement that people should be able to scroll around independently if realtime is important, and expose via Google Hangouts/Slack/join.me/whatever - get rid of the theft prevention requirement and just use Google Docs If you can't pay the money it would really require to build this, I doubt the requirements and perceived value exist - otherwise somebody would have already made this as a standalone product.

The combination of requirements is going to make this pretty difficult unless you can find an existing site that purports to provide secure document sharing with realtime capabilities. It's pretty trivial to update a document in real time one direction, but once you supply people's browsers with a full copy of the document it's going to be very hard to prevent them from copying it. To get anything like that you're probably looking at rendering the text to a canvas element, obfuscating the code, etc., and it's still going to be pointless because they can screen shot it. I guess you could try to see if you use some sort of DRM to prevent copying but that might require you to render the text to a video which isn't impossible but would be pretty wacky. mystes fucked around with this message at 19:48 on Nov 23, 2018 |

And even then, like I said there's the analog hole. Sharing content while preventing your consumers from doing what they like with that content is more or less impossible given sufficiently determined consumer. That's why I suggested just charging them up-front for everything. Like, "$X gets you access to rough drafts as they are written as well as the completed work once it's been edited and published." Then you don't need to care what they do with the rough draft.

Well, I've gotten some good good replies here and I thank all of you. I guess I should make it clear that I don't think I could ever make it 100% theft-proof no matter what and I have to rely on my clients being honorable if they want my business going forward. The closest thing I've found to what I want in ready-made software would be these: RealVNC -- https://www.realvnc.com/en/ MyChat -- https://nsoft-s.com/en/aboutmychat.html And as you guys say, Google Docs or Windows OneDrive but, as I also pointed out, I will be in areas that don't have cloud access sometimes and so it wouldn't be there for me then. Both of the above programs above claim to work locally and I've verified RealVNC definitely does. And as for mychat I could probably use AHK to make a workaround to get it to cut and paste new text to the chat window. But I know nothing about these guys. Maybe I can just tell my client to use the RealVNC viewer app and use screenshots instead of cutting and pasting text. It works locally, appears fairly easy and doesn't crash anything, and would help prohibit work product theft. User uhuh, you are probably right. Right now shelling out 5k or more for this is too much, I am not too rich and if I had that I'd probably buy a second laptop so as the economy crashes I won't have to worry about buying another for a while. I was just hoping that it would be an easier or cheaper proposition in general, I guess. The all-in-one software suite that includes this feature is a few grand and I'm paying for it by monthly installments and haven't properly learned to use it yet, as it involves relearning all my keyboard shortcuts, building up a new user profile, etc. And I've noticed that among other things, since I've installed this suite 2 weeks ago I've had about 3-5 unaccountable BSODs, as well, which may or may not be attributable to them. Anybody wanting to make any proposals, suggestions or whatever, feel free to PM me. Don't put too much effort into it without talking to me though.

I was curious in the abstract about it and looked around, but where-ever I found it was part of big expensive document collaboration suites (e.g. sharepoint, xmind, huddle, et al), so you're probably right in that OP.

This isn't a programming question - this is someone looking for a product to cover a niche case for their work. I'm guessing there are more hard requirements present than a day's worth of work would cover. For funsies though: 1. use an editor and configure it to auto save every minute 2. have a really simple node.js or python server read the file and serve it up 3. have a simple html page that polls your server and returns all of the current text - obfuscate it to make it a little more annoying to copy or hit the API directly 4. have script on your html page render the content into a canvas 5. add some slippy type scrolling so they can scroll through the document within the canvas You could do that in a day, I suppose. And while it isn't secure, unless you were a developer it would be pretty difficult to get around.
