I picked up 20 NFC tags (link) and they seem to be alright with iOS after I (re?)format them to NDEF.

Anyway, I have a few things setup:

• tap to play music in the dining room over a Google Home speaker
• tap to turn off some lights and prep for bed etc
• tap to change some Hue scenes

... and that's about it. I don't have trouble waking up to an alarm, so I don't need to go down that route. Anyone have any fun things you're doing with tags?

Hi all. I am asking this open-ended question (bottom of this post) because I am considering making contributions to an open-source project that would directly benefit me and other users.

Some background:

I have worked with an engineering simulation software called Ansys MAPDL basically everyday for the last 4 years, in both an academic and a professional capacity. It's not necessarily relevant whether you are familiar to that program to participate in this discussion. The relevant thing is that the GUI for MAPDL is written in Tcl/Tk and I don’t imagine it is going to be modernized (because of more modern, but distinctly different, replacements). This is a screenshot of the GUI for reference.

Why do people put up with such an old interface?

The power of the program is not its GUI, but the scripting language that can be run to setup and solve simulations. The program name is really the scripting language name, Ansys Parametric Design Language (APDL). It's somewhat like Matlab. The program also offers an enormous amount of control when compared to the more modern GUI that's been released, since the modern GUI holds a totally different philosophy.

The older GUI is really helpful in certain circumstances because it will spit out a file containing commands that were used in the session. This is a great demonstration of how to run a command or use a setting/config command, but a lot of newer features are buried in the documentation and aren't available in the older GUI.

My coding experience

I know the MAPDL language very intimately, but my experience beyond it is limited to some Perl scripting, and a bit of Python exposure.

Motivation

Open-Source Ansys API

Recently, Ansys started supporting an open-source Python project called PyAnsys. MAPDL is otherwise fully closed source, and this is really the only public-facing API. PyAnsys has basically converted a lot of MAPDL script commands to a pythonic format, hence Python can now be used to interact with MAPDL. This is great for several reasons, but is limited regarding interactivity. Interacting with MAPDL via Python is basically happening in a fancy console via Jupyter notebook or IDE like Spyder. Certain commands will bring up Python-based graphics displays of solid models and results plots, but there isn't a dedicated GUI open all the time.

The Question(s)

My question is whether it is feasible to write a frontend GUI to a bunch of python commands. If you were going to do it, how would you do it? What might you write it with? Would you even do it? Is this a stupid endeavor?

So I'm looking to do an improved version of this project from a couple of years ago that rebuilt the dreamcast VMU into an emulator system that could even interface with a modified dreamcast controller using the original connector. That project was really neat, but it used a raspberry pi zero, which is frankly anemic for running any emulators past the SNES, and I'd like to find one that's powerful enough to emulate the dreamcast itself, but small enough to fit inside a VMU. To that end, my requirements are:

• Must be of a similar size to the pi zero. Smaller would be better, but it absolutely cannot be more than 40x65mm.

• Must have a processor at least as powerful as a cortex A53, preferably something more powerful like the A72.

• Must have a release of armbian (or similar) with drivers for full video acceleration.

• Must be able to drive a display over SPI.

• Must be available. The NanoPi NEO Core 2 is pretty close to what I need, if maybe a bit underpowered, but it seems to be discontinued and I can't find it anywhere but aliexpress at double the list price.

• Composite video out would be nice.

• Analog audio out would be nice.

• Availability without soldered headers and large ports would be nice, like the pi zero or nanopi neo.

Let me start by saying this is a space I am not at all familiar with. I didn't grow up with IRC, my first text editor was Sublime (I'm not from the "EMACS vs. VIM" generation,) so I feel kinda outta touch with what all is going on.

Is there a winner? I feel invested in this topic after seeing a whole slew of posts, blogs, and medium articles posted all over Reddit and HN breaking down how these folks have personally been impacted over the past month or so. It seems to have died down which leaves me with the question of what the outcome was. An even 50/50 split? Libera destroying Freenode? Or Freenode able to hold onto users by successfully preventing efforts to organize a transition?

Without being in the Freenode community, I don't have a feeling for whether Freenode is dead, Libera Chat is "winning" and I don't think there's a good way to get metrics either.

Anyone in this world who can help the uneducated out on the outcome of all of this?

My Goal

I am applying to Canadian universities for fall admission as a CS major. This will be my second degree, and one of the requirements of getting admitted for a second degree is to show that you have a significant interest in the subject. My plan is to get online certificates to show that I am actually dedicated to learning CS and getting a job in the field. I am actually dedicated, I just need a way to show it on paper. I have some experience with software development (only the basics), but there aren't any records of it since it was just informal study.

My Problem

I can't decide which certificates I should pursue. I am torn between EdX and Udemy. I would Tilderinos' help in choosing between the two. I would also appreciate any general advice you may have.

Here are the courses I plan to take on EdX (prices in USD):

UBC's MicroMasters Program in
Software Development - $832

Harvard CS50's Web Programming with Python and JavaScript - $199

IBM's Professional Certificate in
Cloud Application Development Foundations - $169

Here are the courses I plan to take on Udemy:

The Ultimate 2021 Fullstack Web Development Bootcamp - $15

The Complete 2021 Web Development Bootcamp - $15

The Ultimate MySQL Bootcamp: Go from SQL Beginner to Expert - $30

Angular - The Complete Guide (2021 Edition) - $15

Comparisons

To reiterate, I have two goals going into this. One is to actually learn web development, since I would like to become a fullstack developer (but my options are semi-open). The other is to prove to the Canadian universities that I am dedicated to learning and to give myself an edge over applicants.

If I go with EdX, then I have to pay a much steeper price for the certificates. These courses also take a long time to get through and the projects don't seem as relevant to real word applications. But I will also be learning from established institutions like Harvard and UBC. EdX certificates also come with the distinct advantage that a human is checking the problem sets you submit. This will show the Canadian universities that I have actually spent the time and effort to go through the courses and pass them.

If I go with Udemy, I will get through the courses in less time and their projects seem more related to real world projects. If I go through the courses faster, I will also have more time to start on some personal projects, and I can show my dedication to learning through those projects. Personal projects and also volunteer work will also help establish a resumé for future work. The courses on Udemy are a lot cheaper too. But they don't have the same level of verification or prestige that EdX does.

So in summary, EdX has prestige and quality courses, but a steep prices and a huge time commitment. Udemy is cheaper and gives me more opportunities to do personal projects and volunteer work, but it's certificates aren't fully trustworthy from the Canadian universities' perspective.

Final Words

What do you think? Which path should I take?

For those of you wondering, why I am going to university instead of a bootcamp, it's because I plan to immigrate to Canada and becoming a student seems the straightest way of getting PR. I need to leave my third world country as soon as I can, for mental health and economic reasons. I have been mostly unemployed ever since the pandemic started so I can't get work in Canada (or the U.S.) on my first degree (a management degree). I already tried that route. I can't find proper work here either.

Also, I am sorry if I posted in the wrong group, or if I shouldn't have posted it anywhere at all. I desperately need advice on what to do and I don't have a trustworthy network here that can help me through this. I'm sorry and thank you for your help.

So, I'm a privacy advocate (or paranoiac, depending on your perspective). I run both uMatrix and NoScript plug-ins (among others) in my Firefox browser, so I can see when and where websites send calls out to other locations, and block the ones I want ... google analytics, google fonts, google-apis, google tag manager, and gstatic are all ubiquitous out there, probably 99% of websites use at least one of them (PS: Tildes is in the 1%; yeay, Deimos).

And note ... there may well be nothing at all wrong with any of those sites/services ... but Google has a global all-encompassing Terms and Conditions policy that says, you use anything of Theirs, and They are allowed to harvest your personal data and make money off of it.

And I do not accept those terms.

Okay, that's the prologue. The deal is, I have a small piece of documentation, just basic "how to use this" info, for a WordPress plug-in. It is in .html format, with bundled bootstrap and jquery and a few other assets.

Nothing, anywhere in the entire folder, references gstatic. And yet when I open this local, on-my-computer-only html file ... my browser tells me that it is trying to connect to gstatic.com.

Anyone happen to know why/how that is happening?

I'm setting up a server with nextcloud, plex, matrix and some other things I don't yet know, for some friends and family, (about 20 people if I get lucky)
and now I heard of a thing called single sign on/unified login. (Login to different services with the same user/pw and/or login once, access to all services)

so far I found out about Keycloak https://en.wikipedia.org/wiki/Keycloak

is this what I'm looking for? does anybody have experience in this? Are there other/better/simpler solutions for this?

I've put quite a bit of work into my i3 set up recently and I'm curious if the people here are interested in that kind of thing.

I'd be interested in looking through configs to get ideas, and sharing screenshots and such.

Here is what my desktop looks like right now. Let me know what you think.

I have a CalDigit TS3+ dock that I switch between my M1 Macbook Pro and a System76 Galago Pro that's currently running Windows 10 (I'm sorry, FOSS gods). The M1 has no problem using the TS3+ when it's connected or disconnected and reconnected. But the Galago Pro will only connect to the dock if it was connected while booting up. Disconnecting and reconnecting leaves the dock in a state where only the pass-through thunderbolt port works. So my monitor that uses the pass-through for DisplayPort can operate after reconnecting the dock, but no other devices plugged into the dock will. My mouse/keyboard for example don't even receive power in this state.

Oddly when setting up the drivers for thunderbolt I found that the only drivers available are for Intel's NUCs. IIRC someone on reddit said that this is actually the software I need to install, so that's what I did.

Any help getting the dock to work better is appreciated! Currently I need to reboot the laptop every time I switch back from the M1 to the Galago Pro.

I recently set up kubernetes to run on an old laptop. The goal was two-fold, 1 learn kubernetes and 2 setup an instance of nextcloud. I've managed to set everything up with cert renewals for my domain and enabled dyndns in case my provider changes my ip. All well and good and quite nice learning experience! Now I would like to also start running my own email server and have some questions. Is ther any that have a helm chart that is easy to setup in kubernetes? Since I am running this from home I imagine I'm more likely to be classified as a spammer. What can I do to minimize the likelihood of that? I read somewhere about reverse DNS, but not entirely sure if it is possible to do given I am running it all at home via a regular ISP.

I have a Xiaomi Redmi 4X device with 2GB RAM and 16GB on-device storage.

Yesterday, I setup PostmarketOS on it, and it works well enough. WiFi and display work well, although no 3D acceleration and no telephony at all. As such, now it is just another device on my home network, except that I can ssh into it to do some basic stuff. Right now it is setup as a Syncthing node to backup my Keepass db and personal knowledge base written in org-mode, but I would like to use it further, and looking for ideas.

Two things to consider, though. First, I don't want it to overcharge and bust the battery. Before when it was on LineageOS, I had a magisk module acc so it would charge only 40-80%, and is largely the reason why the battery holds up pretty well after 5+ years without swelling. I will take further look into it over coming weekend and try to make something like it for the alpine kernel included in PmOS. Second, while on charging the phone keeps vibrating repeatedly. I have no idea how to fix that one, but would like to strat given pointers. (I have never done kernel dev in my life)

So, any ideas on what I can use this extra computer in my metaphorical basement welcome. Thanks in advance.

It is late... and I am pretty much finished with migrating to a new VPS provider. I got rate limited with two domains, but I'm running everything through Cloudflare. Do I need to bother with LetsEncrypt on the VPS itself? When I check the domains, the certs from CF are working nicely.

This is my first time using CF.

Quick edit while I pretend I can sleep.

I’m thinking that CF will cover me for 443 and route all traffic there. I’ve got wildcards set for domains with services that require other ports — which is working. All CF is doing is caching my sites, right?

I'm currently developing a minimal userscript manager who's main goal is to be fully auditable by any user in only ten minutes or so - my prototype uses less than 300 lines of javascript, and I'm trying to keep it that way.

To get the codebase this small, however, I have to be very picky with what features I implement - most notably, the code editor has to be very barebones. Are there any features that I'd be shooting myself in the foot by not including?

For example:

• syntax highlighting
• cloud sync
• regex url matching
• fullscreen editor (currently, it's just a browser popup - the intention is that you write code elsewhere and paste it in)

Any feedback is greatly appreciated!

I've been learning a bit more Python, going through a Udemy course to expand my skills a little. One of the programs the course guides you to make is a little dictionary, but it currently only runs once and then quits.
I'd like to adapt it to use a nice TUI that keeps itself open until the user specifies they want to quit, using something along the lines of npyscreen. However, this library uses classes, and that's not something I'm yet familiar with. I'd rather have an understanding of what classes are, how they work, and why to use them before I take the plunge and start fiddling around with npyscreen (although I'd be interested to hear if you think that I should Just Do It instead).
Can anyone give or point me towards a good explanation of the what, how, and why of Python classes? Or better yet, a tutorial that will give me something to write and play with to figure out how it all fits together?
Thanks!
