      Hey Tildes!

      I've got a static, basic website, HTML and CSS. It's one page only. But I'd like to create a second page with some more private content that is password protected.

      I know that I can accomplish this via .htaccess but what I don't like about this method is that when the user navigates to the page, they get a pop up asking for a username and password. What I would like is having the user navigate to the page, and then they are met with a simple form asking for just a password (no username). After they enter the password, the "veil" lifts or the page forwards and they get the private content.

      Here's the thing... the content really only needs to seem private. It's not super secret, personal information. I don't want it indexed by search engines (nofollow), and I want it basically hidden, but the password is only there to make the user feel exclusive. If some tech-minded person encountered this page and jumped through a bunch of hoops to get in without the password, it's not a big deal to me. In reality, 99.9% of people accessing this page will not be able to bypass the password.

      I'm guessing this can be accomplished easily in Javascript, but I don't really know much Javascript apart from finding code snippets and plunking them in. I also want to be able to fully design the password entry page so that it looks branded, so a code snippet plunked down into my HTML doc would be great for this.

      If there is an easy way to actually protect the content behind the password, that would be excellent. In this case, I imagine it would be much like a news site with an ad-blocker-blocker. Just some kind of pop-up that blocks all the content. Enter the password, and you're in.

      Anyhow, I hope I've described what I'm looking for accurately enough. Anybody have any easy and quick ways to accomplish this?

      I'll be writing a relatively large piece of scientific code for the first time, and before I begin I would at least like to outline how the project will be structured so that I don't run into headaches later on. The problem is, I don't have much experience structuring large projects. Up until now most of the code I have written as been in the form of python scripts that I string together to form an ad-hoc pipeline for analysis, or else C++ programs that are relatively self contained. My current project is much larger in scope. It will consist of four main 'modules' (I'm not sure if this is the correct term, apologies if not) each of which consist of a handful of .cpp and .h files. The schematic I have in mind for how it should look is something like:

      src
       ├──Module1 (Initializer)
       │         ├ file1.cpp
       │         ├ file1.h
       │         │...
       │         └ Makefile
       ├───Module2 (solver)
       │          ├ file1.cpp
       │          ├ file1.h
       │          │...
       │          └ Makefile
       ├───Module3 (Distribute)
       │          ├ file1.cpp
       │          └Makefile 
       └ Makefile
      

      Basically, I build each self-contained 'module', and use the object files produced there to build my main program. Is there anything I should keep in mind here, or is this basically how such a project should be structured?

      I imagine the particularly structure will be dependent on my project, but I am more interested in general principles to keep in mind.

      So, the black installation doc tells me to install black by using: pip install black

      I don't know what pip is so I go read about it here. These instructions tell me that pip is already installed since I have the latest version of Python installed.

      That's wonderful, right?

      Not for me. How do I install black?

      Black can be installed by running pip install black.

      Do I run this from the Terminal (I'm using Mac)?

      I've been trying to set up a reliable lightweight solution for high quality, low-latency webcam (v4l2) streaming from Linux server to browsers, allowing for small (1-5) number of concurrent viewers.

      The obvious choice here is WebRTC, which when used through browser APIs, works wonderfully. It has low latency and automatic quality adjustment depending on network performance.
      I also checked out RTSP and RTMP, which are not supported without browser plugins. Next candidates were DASH and HLS, but while they provide high quality, they also have high latency.
      For a while I used MPEG1 streaming through Websockets (using jsmpeg library), which worked and had low latency, but the video quality was bad.

      Back to WebRTC - It seems like reliable, lightweight and maintained projects are really hard to find. So far I've found a few WebRTC media servers, but they're overkill for my use case:

      • Janus
      • MediaSoup
      • Kurento (unmaintained)

      I also tried implementing this functionality using low level Gstreamer elements in Python using PyGObject, but that's proving to be rather complicated with a ton of extremely low level implementation details.

      If anyone has tried doing something similar, I'd really like to hear what (if any) problems you had and if you found any sane solutions. Next thing on my list is using headless Chromium in combination with Puppeteer, but I'd really prefer more lightweight solutions.

      I just received a mail from my own e-mail address, hosted on Gandi on my own domain name. It said that the sender has hacked me, used malware, keyloggers and RDP to get my passwords and copy all my files to his own computer, and took videos of me while watching adult content using my webcam (I never noticed the light turning on for it). Claims they've been doing this for a few months. Gives a bitcoin address and wants $1000 (a sum I can't and won't give, don't even have a fraction of it) in 48 hrs, or else will share the videos with my contacts. It said something about a pixel the message included.

      I viewed the message from K-9 mail on android (which didn't tell anything about pixels or whatnot), and when I went back on my computer to check the headers and stuff, the message was deleted.

      Now, is this some sort of phishing or or have I really been pwned? I feel like it's just phishing, but the message deleting itself kinda gave me shills of fear. I promptly changed my password for the mail account.

      I have just graduated from uni, and am preparing for masters next fall. I'm a humanities student, but have some programming knowledge. Currently I'm looking for literary translation jobs, but should I fail that, I want to find some light freelance work (so that I can spare more time to my studies), and looking at e.g. freelancer.com, Wordpress is still quite popular.

      What are some good introductory material for Wordpress and PHP, that preferably does not assume total beginner to programming? How much can I expect to make, for how much effort? I'd be content if I could make $200-250 w/ 3-5hr work per day, or a couple full days a week, that's all I really need and such hours would mean that I could keep on doing such work even when I'm writing my thesis. I'm in Turkey, FWIW.

      Hi all, Hope ya'll doing good. I am done with windows. So I want to switch to linux. I have used it a few times. I just wanted to know, how long will it take to have it setup? Also, I am learning data science. Will switching to linux have any serious implications? Thanks

      Having recently installed OpenBSD, "join the mailing list" is a piece of advice I've come across a few times now. But being a hip young teenager unfamiliar with what exactly that entails, I thought I'd go through how I've attempted to do that as a sort of sanity check, as some of you old farts will probably be much more familiar with them than I am.

      First, I went to the OpenBSD Mailing Lists page and scrolled down to the "Managing list membership via the web" section, which took me here. After following the sign up instructions and logging in to my email to confirm my registration, I attempted to navigate to the misc mailing server, at which point I subscribed to that specific list and again confirmed my subscription.

      So, I'm relatively sure I'm now subscribed to the "misc" OpenBSD mailing list. However my question is mainly...what exactly do I do now? Specifically, will new messages in misc automatically go to my inbox, or is there something else that must be done? I'm relatively sure the webpage can't be used to access messages from the mailing list.

      Hello everyone!

      I've recently got an idea for a Database as a Service I'd like to create. The only issue is - I don't know how to create or host a database!

      I've only ever used Mongoose/mLab with Javascript, and a minimal amount of Postgres with Python.

      If I'm looking to create a database that will, eventually, be able to store images, songs, and videos, where should I start my homework?

      I can create the backend and the frontend with no issue - just stuck on this part here. If it's of any relevance, I most frequently use the MERN stack.

      I'm currently looking for a new monitor and I have the ASUS MG279Q, the ASUS PG248Q and the ASUS MG278Q. Now, my setup is not the highest end, but decent with an i7 and a 1060 3GB, and there are three concerns I have currently not found an answer for:

      1. The (potential) difference in quality between the MG279Q's IPS panel and the MG278's TN panel
      2. And the delay difference, the TN panel having a 1ms response time and the IPS' 4ms
      3. If my setup can even handle 1440p/144Hz (I don't need to play on the highest settings, nor do I need to reach those 144 FPS), in which case I would tend more towards the PG248Q

      I'd love to upgrade towards 1440p as the screen real estate would be good for working (which I do a lot on the PC) and I would, I could later upgrade my GPU if the performance in games isn't satisfactory. I think my setup wouldn't have any issue handling day to day tasks and if need be I can play on lower resolutions or lower graphic settings. Also I wonder how large the difference between the IPS and TN panel is and if it's noticeable, particularly with colours.

      Does anyone of you have experience with the subject or with the monitors named in particular?

      I have been interested in making the gradual career change to software development from my current humanities field. This stems from a handful of different places. Of course the pay and flexibility are strong drivers but I like the idea of a field that is somewhat of a creative expression; one where you can manifest your knowledge and experience into something tangible.

      I have no experience with programming other than SQL use in ArcGIS and am hoping to gain some knowledge about the field; so anything would be helpful. Whether what to expect from this line of work, where someone with no experience should look to get started and what to expect, personal journeys, etc.

      Cheers!

      Anybody here have a good setup for batch-downloading articles/news from several sites you specify, similar to youtube-dl but for general websites? I'm sure it could be scripted with not too much effort but I'm interested what polished solutions there are.

      The idea would be so people with rare internet access could go to a hotspot weekly or something and sync that week's worth of content.
