    Just another QR Code Page

    Posted: 19 Jan 2021 09:30 AM PST

    Got really tired of using super slow and bloated QR Codes websites which rather aim to sell t-shirts than to generate QR Codes.

    So here's my attempt to make the QR Code world better:

    • No ads
    • No transmitted data (local browser only)
    • No shop
    • No limitations
    • Free ofc
    • Dark / Light Theme :)
    • As simple as it can get

    UX/UI for devs - Looking for online courses

    Posted: 19 Jan 2021 08:43 AM PST

    I started as a junior full stack dev maybe 5 years ago but I've been doing exclusively frontend work for the last couple of years.

    I'm worried that I've always been blagging it with UI stuff and have normally had designers working with me to do the real work. I enjoy contributing to that side of things but I lack any real foundational knowledge. I also feel like I want to learn something new which gets me out of my code editor for an hour or so a day.

    Could anyone recommend some resources for learning UX/UI design suitable for frontend devs? Free ones would be great to start with but I wouldn't mind paying a one off fee if something's highly recommended.

    Thanks

    How to get rid of a client?

    Posted: 19 Jan 2021 12:32 PM PST

    So here i am, wondering how I can get rid of this client whom i made a small professional website more than a year ago, and still writing me emails or texting me for unrelated questions/favours, mostly about problems with her email accounts or (that's the latest one) about 'configuring' her brand new macbook.

    Thing is, i made the mistake last year, during one of our first meetings, to help her importing an external email account on her gmail, so she was very happy and i quickly became her 'guru' for everything computer related... So that's on me, at least partially, i guess. I was just aiming to bring some work in house and i thought it was a good way (it worked) to impress her.

    Now, i do website development as a side gig, and i am so not interested in being her helpdesk for... life. I must say she's offered to pay me more than once for these services, but i always said it was a 'quick thing' and declined, hoping that she'd one day stopped asking these kind of 'favours'... But it's not happening.

    So... Given this as a background, how do you deal with this type of clients usually, or, what do you think is a polite way (she's always been polite on my regards) to ultimately cut the business?

    Question about using express.js with nuxt.js (specifically with routing)

    Posted: 19 Jan 2021 02:25 PM PST

    I'm building out a web app (mostly as an excuse to learn vue and get practice) and I'm currently using both express.js and nuxt.js

    I'm hoping someone can walk me through the main differences between using nuxtlink routes for pages and using the express.Router() object (and when you would use one over the other).

    My instinct is to use nuxt/nuxtlink routes for user navigation "front-end" stuff (like typical nav bar links to other pages).

    I would use the express.Router() object for directing specific server requests outside of just GETting content delivered (like if I had to handle POST requests or if my web app also had or needed an API).

    To be honest though, that's just a feeling I have. I'm still not positive what the difference is between what's happening under the hood, nor if it's a meaningful difference. I would really appreciate any help or links to good articles to read. I'm just having a hard time putting together where different parts of the stack/framework are being used. It seems like there is so much overlap...

    Thanks in advance!

    how to add a feature to change the language on my website?

    Posted: 19 Jan 2021 03:57 PM PST

    So I am building a website, designing it and publishing it for my personal portfolio and eventually my future law firm. Right now I am a software engineer student but will pursuing law school in a few years here in England. I would like to translate my website into languages I speak (Italian, Spanish, French, German, Russian, Chinese Mandarin, and Hebrew). I also understand two dead languages (Latin and Anglo Saxon) and would like to put them on my website just for the fun of it.

    My question is:

    Is there a way to code a feature where you can automatically change the language and if so what language would I need to do it in and how?

    Advice or reading material on building a scalable social network like Yik Yak/Twitter?

    Posted: 19 Jan 2021 09:06 AM PST

    Background

    I want to make a Yik Yak clone, for fun. If you're not familiar with it, it's a geo-local social network where people can make anonymous posts, vote on them, and comment on them. You only see posts near you within a dynamic radius based on the user density in your area. You can see your own post history but since it is anonymous, you cannot view anyone else's. Posts are sorted chronologically, comments are only tied to the post itself and not other comments, but I'm interested in knowing how having comment trees like Reddit would affect my needs.

    Here is a simple class diagram of my model. I left out some minor things like the date/time of posts and comments, etc. If that is related to the graph, do let me know!

    What I want to know

    I've heard that using only relational databases is not the best way to go; that you often need special caching mechanisms and a graph database on top of the relational one. I have so many questions:

    • What specifically would a graph database be good at in this scenario? I can see how it would be useful for something like Facebook or Instagram, where you have friends and you can see "friends of friends" which would be a pain to implement in SQL, but how would a graph make my life easier here?
    • Is some sort of advanced caching necessary? Am I caching results from the graph or from the SQL database?
    • What would I put in the SQL database and what would I put in the graph database, assuming I do need one?

    A FOSS, Clean and Quick Way to Learn Tables (Drilling/Flash Cards)

    Posted: 19 Jan 2021 01:19 PM PST

    A FOSS, Clean and Quick Way to Learn Tables (Drilling/Flash Cards)

    My little sister had difficulty learning multiplication tables, and we realised that drilling (asking multiple questions rapidly, and moving on quickly) was giving the fastest results. Most other websites or apps that do this are cluttered with ads, so I though I would build a clean no bullshit app that does this.

    Its still a work in progress, and the settings don't work. I was thinking of adding accounts so you can track your progress. Let me know of other suggestions. Hope you guys find it useful :)

    App: https://www.tabill.tk

    Why use JS to change CSS?

    Posted: 19 Jan 2021 01:12 PM PST

    I'm probably getting ahead of myself here. I'm taking an online course about web development and I don't understand why you would make adjustments with chrome tools using javascript to manipulate CSS when you can directly adjust your stylesheet. If you can articulate my question better than me then do it. Thank you.

    Obtaining Client Signature

    Posted: 19 Jan 2021 11:02 AM PST

    Hi, I've been wondering how people usually go about sending their client a contract and obtaining a signature from them in a hassle-free manner as I don't want to add more steps than necessary for them. I'm using a modified version of the Killer Contracts boilerplate. Note that this is for situations where a physical signature is not easily obtained. Any help would be greatly appreciated.

    Why are support community forums always such a mess?

    Posted: 19 Jan 2021 07:44 AM PST

    I mean, for example just take a quick look at my newest discovery: https://github.community/. Even worse is the dark-mode-beta category:

    https://github.community/c/github-help/dark-mode-beta/65

    Like, why are people there saying the same irrelevant nonsense again and again?? Literally 90% of that forum is just pure spam. People there literally create an account and open a new post just to post...THIS:

    "I really like the dark theme"

    Or go into the one of the bigger threads, like for example:

    https://github.community/t/dark-mode-theme-with-less-contrast/147845/102

    https://github.community/t/a-dark-mode-with-more-contrast/147815/21

    I mean, these threads are a mess in general because people just HAVE TO give their opinion about how the background of the fucking opt-in optional dark mode is too dark or too bright by like one hex number because well they use this chrome extension which does it perfect for them and that's what they used before and blablabla. But not just that, look at the amount of times a staff member had to merge another topic into one of those. Because people are apparently too fucking stupid to take ONE SECOND to look at the forum to see that there are already four open threads about your non-problem.

    And it's not just this forum. It ranges from specific github repo issues, to apple community forums, to discord or slack #support channels, to all kinds of software project support boards.

    It also seems like some people don't understand the structure of forums in general. Literally every other thread has someone in it stating that they like or dont like the GitHub dark mode in general. Has nothing to do with the thread title or the problem explained there, but I guess that's okay now?? Is this a cultural or generational thing? Even if you didn't grow up in the forum era, isn't it fucking obvious how this is supposed to work?

    These protagonist syndrome people are everywhere. And I don't get it. Like, sure, okay, suppose you abolutely WANT to publicly say that you like the GitHub dark mode, alright? What is the first place you'd think about putting that statement? Tinder? Nah, wrong place. Facebook? Idk, there are only your irl friends. Twitter? I mean, seems like a nice option but who of your 7 followers will really care? Reddit? Oh, yes, that seems perfect...but wait...

    GitHub Support Community Forum? YESSS! BINGO BINGO! IT LITERALLY SAYS "GITHUB" IN THE NAME (i mean it also says "support" but well...) SO WHAT COULD GO WRONG, JUST GO THERE AND SPAM IT IN. SO BRAVE, WOW!!! GREAT OPINION!

    fucking hell.

    Also, here are my all time favorite posts of that forum:

    "It works fine so no errors"

    "Everything is cool: It is very cool I would like to have more themes."

    "it is really good move to have dark mode in github website but I think the colors are more darker it should be a bit lighter by 3%. thank you for the nice new feature keep it up:laughing::okhand:"

    "A small idea about backgrounds :D: my idea is to make a custom background, something like a wallpaper in windows where you can put any image you want. and automatically toggle light/black theme to that wallpaper ( if image is light - light, if darker - black )"

    "i just set this issue from comments help thanks guys have a good day !!"

    That last one? Notice something? There's a link hidden on the first exclamation point. See it? It points to kitchenmeg dot com. This is another phenomenon I discovered on this forum. I've seen these hidden links pointing to dubious websites a couple of times now and I don't get it. Any ideas what these people try to achieve with that?

    Separate front and back ends?

    Posted: 19 Jan 2021 10:07 AM PST

    Hi. I'm not entirely lost but I wanna ask at least if my way is somewhat sane. So I have my simple React website on github pages. It works fine. Now I want to show some data which I would occasionally scrape at my VPS server which will have django for api end points with gunicorn and nginx as a reverse proxy. I've seen multiple methods of achieving this. Some recommend having both react and django on same vps. My question is if I fetch data from the react site which is at github pages from my vps would it work ok? Or there's something more to take into account. Such as cors? Im not entirely new to web dev, but the more I've been researching the more lost I seem to get. Thank you and sorry if its a stupid question

    Partial Application and Functional Programming in JavaScript

    Posted: 19 Jan 2021 08:45 AM PST

    I have to make documentation about project that I know almost nothing about.

    Posted: 19 Jan 2021 05:04 AM PST

    Hello guys,I've been working in this place for 2 months now (this is my first job too) and I've been requested what the title says. It's a very big and complex project and I've worked so little in it. My boss expects me to spend at least 2 hours a day doing this documentation and I don't really know even where to start. Also it's the first doc I make because previous ones where just school projects that also I have made and I know about.

    Any tips for this poor soul? Thanks.

    (Sorry for bad english).

    Edit: Thanks everybody for the answers, really helpful!!

    Should I go to a Bootcamp or just be self-taught?

    Posted: 19 Jan 2021 03:47 PM PST

    I went to those free Bootcamp session and the guy that taught didn't seem like a good teacher but that's cuz he just finished a Bootcamp. Even the TAs that were helpers couldn't answer a question of mine. I also see people's portfolios online its like a tik tac toe, calculator kind of projects. Is that what people pay 10k +to build? Am I missing anything else other than a support group to get answers?

    I kinda don't want to waste money if all there is like a udemy course as I kinda like self learning, but I do value a support group to get my questions answered fast. Also wondering if I lose employability because I don't have a certificate from these Bootcamp. Saying on my resume Im self-taught, maybe is a red flag for employers?

    TL:DR

    1. Is there more value going to a Bootcamp vs self-taught other than building those project portfolios? Like getting to exclusive job referrals? Or is it ur still on ur own to apply?
    2. Is there a good place to get some structure in a course? Ideally like on-demand get ur question answered when I get stuck building my projects. ( I def need a place where I can get my questions answered fast when I'm stuck) Did I hear about Odin and freebootcamp? Is this the right way to go for self taught?
    3. How can I stand out and is "being self-taught" going to hinder myself from getting an interview?

    About me: I graduated from a University in Accounting/finance working at a bank. I watch a lot of youtube tutorials at 2x -3x speed and a DIY kinda guy. I like to google stuff a lot. If this helps in giving advice :)

    I have blindspots because I work on my website so much. How would you improve the user experience on my site? What problems or areas of improvement do you see that I may be overlooking?

    Posted: 19 Jan 2021 03:24 PM PST

    My site url is: https://nextlevelartwork.com/

    The biggest things I see are:

    1. The homepage banner, on mobile, looks like shit. I need to set up a separate one optimized for mobile. On desktop, & tablets, it looks great. But mobile, the text overlays on the image poorly, and the load order is also weird in the sense that if people are scrolling before it's fully loaded, they don't even see the full image or message. This is huge because first impressions are everything online.
    2. On product pages, the product variant buttons/swatches have a weird loading glitch where it first shows the original button formats, but then shifts to another format provided by a third-party app on the site.

    What else do you guys see on there that disrupts the UX and could cause people to bounce? I'm so "in" my site all day long that some fresh sets of eyes would be really helpful to expose some of my blindspots.

    thanks!

    What is the best methods to deploy a MERN/React app for production

    Posted: 18 Jan 2021 11:35 PM PST

    Hello everyone

    So now, the web app is complete, how should I deploy it ? We are definitely going to use something like PM2 but should I :

    - Create a build and let a web server like Apache or Nginx server the static files

    Or

    - User something like "Serve -s build" and configure a virtual host as a reverse proxy

    Or

    - Something else

    Most tutorials and books seem to skip this. What are some other useful tips for creating a production environment?

    I m rly curious about how do the pro do this.

    I have a ubuntu 20.04

    Apache 2.4

    Question about a project

    Posted: 19 Jan 2021 02:59 PM PST

    So I'm a beginner and thinking to redesign a restaurant page for a restaurant. They do have a restaurant website which isn't very good and they have the menu over there as well. But I just don't know the best way to do it. Do I just find an API for that? Or just start making it from the scratch? Sorry if that's a stupid question, I'm not a complete beginner tho.

    Session Replay Tool that can be enabled/disabled dynamically for a single user session

    Posted: 19 Jan 2021 02:55 PM PST

    I'm aware of products like FullStory and DynaTrace which can collect user session information based on different rules. One thing I haven't seen anywhere so far is being able to collect session information dynamically for a single session. Here is what I'm imagining: In production, collecting session information is switched off. An end user calls tech support with a problem. The tech support enables a flag and is able to collect session information for just that one user as they navigate through their particular issue. Then tech support switches the flag off and the info is no longer collected. It seems like something like this would be really useful but I can't find any details of any product paid or open source that at least advertises this kind of thing. So, I was curious if this use case is anything anybody else has explored and if they had discovered any products that have this capability. Thanks in advance.

    Site speed optimization help/freelancer help

    Posted: 19 Jan 2021 02:48 PM PST

    Not sure if this is the right forum for this, but here it goes.

    I hired a freelancer through a well known site to fix my horrible site speed. They had great reviews and references, but after they were given access to my site, there was malware detected, and I had to restore the site to a version before they had access.

    As a result, I am a bit gun shy about giving access to my website, and I am not an expert in this. I have read articles and tried a couple of things, but it is a bit beyond my capabilities.

    The worst part is that my site was performing extremely well, and my click through rate was better, as was my organic traffic.

    My question is, as someone that doesn't know anything about the back end of web dev, how do I get my site speed boosted? Is it something I could do? Or could I be walked through it with out giving someone else access to my website?

    When to switch to websockets?

    Posted: 19 Jan 2021 02:45 PM PST

    I am programming a game and currently I use regular http requests until a user chooses a game and starts it . Then I switch to socket.io. Do you think I should use the websockets directly after the login? Is it better to manage more socket connection but have less requests or the other way round?

    Where can I get this super common kind of stock photos?

    Posted: 19 Jan 2021 02:45 PM PST

    So I have kind of an issue, the designer of our team left us with just some AdobeXD prototypes, not even the files, in which he used a lot of what I presume are stock photos. Is there a way to get stock photos that match this style? or even the same assets. Not just iimages of real people, but this kind of "drawing style", I think it is super common, but I'm not sure where to find it.
