Whether you're new to distro installs or aiming to delve deeper, feel free to ask any questions here - remember, no question is stupid!

I'll do my best to answer, and if I can't, someone here likely can, or at least guide you in the right direction.

Background: I've been a Linux user since 2007, starting with Ubuntu Feisty Fawn after losing my Windows XP product key. I've performed countless installs, worked in web hosting NOCs, and use multiple distros daily, including Proxmox.

If you prefer, don't hesitate to PM me directly!

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

I'm in a bit of a rutt with my journey to learn how to write software, and I really have no idea where to go from here. I've taken a bunch of software engineering courses on edx.org, and I've done a few personal projects with what I've learned, but I still don't know enough to be able to contribute to open source projects or make anything useful.

TL;DR
How can I learn to actually make things?

I'm looking for a project to contribute too. I'm not that experienced with programming, so I want something that isn't too complex. I'm also looking for a fairly young project. Big, mature projects don't really have much that a newbie can work on.

Hi folks,

I figured this would be a good place to ask a rather simple question.

Where do I start to learn to code?

I'm in high school, so I have (some) time to dedicate to it, and it seems there are a plethora of websites/resources out there, so I ask: what do you recommend, and why has it worked for you? I have no prior experience. I believe that this would really help out in the long run, as I will graduate high school with an Associate's Degree in Business. Thank you!

EDIT: Thank you for all your responses! I'll start with Python and move on from there. You guys have been a great help, and I'll vote you up or reply.

I will soon have a home and figured now's the time to do a proper home server, especially since it's going to come with cat 6 run from the main panel to just about every room. I code for a living, but at the same time network is a massive gap in my knowledge, as are servers, and I was hoping to use this as a learning moment as well as just a way to optimize things. I've been doing research for a few weeks now on and off and feel like I've got more questions than I started with, so I'll just vomit them out and if anyone has some guidance I'd really appreciate it.

Some information:

1. I'm willing/able to spend to get quality/simplicity. Time is the much bigger crunch for me right now, and I'd much rather buy something that works even if it costs more than cobbling together some deals.

2. Related to 1, I'd like this to not become my fulltime second job/hobby. I will at some point try to expand to a full home lab, and do want to use this to learn about things I feel I should understand better for general knowledge and my career, but i'd love for core functionality to mostly "just work" after configuring so when I don't have time to do that I'm not stuck telling everyone "oh yeah it'll be broken until I find time to fix it".

Things I know I want-

1. Some sort of NAS. From my research Synology comes up a lot as the "it's expensive but it'll just work" option, and I probably want something like a 4 bay of NAS specific several TB HDD's in something like raid 5/6/10. Pricey as hell but I'm most willing to spend on this as the cost might very well be split by the family members who want me to guinea pig all this.

2. I will have a camera system and would prefer to not have it sending data outside my network. This is the area i've looked at the least, as it's a little farther down the road, but I know others who have things like Arlo and lets just say i'm not super impressed. Obviously this brings up question like remote access to said camera's and where I'm storing the data (nas? Somewhere else?)

3. I'd like to mess with a media server. Plex/Jellyfin constantly come up in my research, so I'll be looking into those, but I've also got a bunch of audiobooks that I'd love to be able to easily share, and I think there's software for that stuff as well.

4. Pihole strikes me as the other "well if you're going to do this, you might as well" option that i'm aware of. Realllly need to better understand networking in general, but I hear these days it can kinda be installed and quickly configured and then left to do its job.

5. Related to all of this, Casa OS keeps coming up as a very good tool for a beginner like me, since it streamlines the handling of docker containers and also file sharing. However it's not really an OS, since it must actually run on Debian (i think?) for now (zima OS still in testing?).

Stuff I'd like to mess with but doesn't have to happen right away.

1. Eventually the aforementioned NAS would be backed up offsite to another NAS at another family members house, once I know what the hell I'm doing.

2. Proxmox constantly comes up as THE tool to use, but it leaves a lot of questions for me. Obviously if I start trying to do lab environments and screw with VM's it's going to be great, but my understanding is that I probably don't, as a beginner, want to say load up a device with proxmox and then have it host debian which installs CasaOS as it'll get a little more tricky to have everything talk right? Unsure on this part.

3. Anything else I'm forgetting. One issue I keep having with this is a LOT of the information out there is either too complex for me to really grok or just says "well yeah you could do ANYTHING with this" and it just sorta assumes I know what the options are. If there's anything else worth checking out I'd love to know.

Hardware I've come across-

1. Synology - Already mentioned but seems like they're a common go to for a "more money than skill/time" situation like mine.

2. Zimaboard - My understanding is it's underpowered for its price, but the main draws are that it's VERY low power, small, and quiet. What it could actually do from my list above is where i'm unsure. I see people are supposedly using it for Plex servers and what not, and I'm pretty sure it's not going to make any kick ass lab environments, but being quiet, small, and maybe a bit closer to plug and play seems tempting (I know they make the blade and a few other products but it all seems greek to me).

3. Various mini computers - I've got a minisforum machine from several years ago that I currently use as a living room computer for light gaming and mostly playing movies and the like. Not sure if i could just wipe it and convert it to be the starting point (more on that later). I know used 1 liter mini pc's from companies like HP are also popular.

4. The MS-01 - Similar pile as the last one but my understanding is this is the kind of thing that's probably really cool if you actually know what the hell you're doing. I'm 99% positive it is vast overkill for my purposes, but I'd like to eventually get to the point where I could understand why I might want something like this. My understanding is if I knew what I was doing I could probably drop proxmox on this and do everything I could ever want and more, but I feel quite far from that.

Some general questions I have -

1. The thing that kicked this all off is my new place likely having fiber, and cat 6 drops throughout the building. Architecture is something I'm still a little shaky on. I assume i'm going to need my own modem/router (just because the cox routers are meh and not really configurable from last I checked), and then that routes to the server first???...or something(seems like a must if you want the pihole to do anything)? I've seen lots of niffty network diagrams at this point but they're all from people WAAAAAAAAY beyond my skill level doing much more ambitious stuff, so it gets hard to understand. If anyone has a simple home network diagram/guide to look at I'd really appreciate it.

2. I'm just in general going to need to learn more about networking, especially in a home environment. Should I eventually get those camera's set up, I want to understand how to let them talk to internal storage and what not ,but not get out to the web...or..something (again remote access seems nice, but also like a massive security concern). I know speed is also a big factor i'm going to need to better understand. Having a fiber connection in only to be bottle necked by a crappy router or a 1gigabit port is just a waste of money, so that's something else I'd like to better understand.

3. I'm a little unclear on how to deliver the media in a media server to the various screens throughout the building. I've got cat 6 to all of them, but I suspect i'm still going to need, at the very least, a cheap computer to hook up to it and then display the image to the monitor/TV? This is why I assume I can't just wipe my current mini PC and reuse it as a server, because I still need it to receive the data from the home server (or at least a web browser?). A part of me feels like if I got a powerful enough server it should be able to server the media direction to the screen, but then you'd need some sort of HDMI/DP drops as well from the server to all your screens?...or something?

Sorry for all the rambling but I've got an odd mix of knowledge and ignorance so it's been a little difficult to research when half the video is stuff I already get, and the other half blows past me or just assumes I know about the parts i'm trying desperately to learn about.

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?

Those that have pursued a career that deals with any type of computer science, what advice would you give to students before they get a job in it? What do you do on a daily basis? What would you have wanted to know before you started?

Okay, I know the obvious answer is the history of the files. But how can I, from the command line, really understand what is hiding inside that .git directory?

Today I was doing one of my periodic disk space audits, trying to figure out where my usage goes. This comes from having a 64GB drive mounted as /home on my Linux laptop. I found some 15G of old video files to delete today, so I'm no longer as pressed for space. But my interest was piqued by one thing I have downloaded from Github that is ~120 megs for a very simple program. Poking around further I find that most of that usage is a single file:

$ ls -lh withExEditorHost/.git/objects/pack/pack-df07816cd15fb091439112029c28ebc366501652.pack
-r--r--r-- 1 elijah elijah 102M Mar 14 23:28 withExEditorHost/.git/objects/pack/pack-df07816cd15fb091439112029c28ebc366501652.pack
$ file withExEditorHost/.git/objects/pack/pack-df07816cd15fb091439112029c28ebc366501652.pack
withExEditorHost/.git/objects/pack/pack-df07816cd15fb091439112029c28ebc366501652.pack: Git pack, version 2, 299 objects
$

Is there a unzip or tar xzf equivalent for Git pack files? Naive usage of git unpack-file is only generating errors for me.

TLDR: What programming language would be useful for taking info in an excel file and producing a text file (that is organized and arranged in a particular way) containing that info? Which would be useful for this problem but also helpful in general? And also, are there any recommended online courses where I could learn it?

I have no real experience coding or anything but have always wanted to learn. Recently at work we've encountered a problem. My boss had created a matlab program in order to take text/numbers from an excel document and transfer them to a text file, but in an organized way.

Say you have something you call "Pancakes" and the cell next to it has the number "3", as in there are three pancakes. I want to be able to create a text file that would read something like this:

NUMBER OF PANCAKES

• Pancakes: 3

We recently have changed around the format of the excel document for a different item, for example "French Toast". I've tried to mess with matlab briefly but was unable to change the program to compensate, and I no longer easily have access to matlab.

I'm seeing this as an opportunity to learn some programming and also fix some stuff at work. So what programming language would be useful for fixing this problem? Which would be useful for this problem, but also helpful in general? And also, are there any recommended online courses where I could learn it?

Thanks for any help, I appreciate it.

Hi, I need your help to learn pentesting.

I'm programming for several years. I'm really good in C# and can write moderately complex apps in Dart, Python and JavaScript. I'm in highschool and work for software development company as backend developer. But general programming starts to feel so boring...

I've started to watch LiveOverflow on youtube (no link, there is no wifi here and I don't want youtube to drain my data) and it was so interesting - so I tried it. I've tried few CTFs, read many writeups, and now I've discovered CTF hack the box.

When I know what to do, I have no problem googling and researching and later applying my knowledge. But I often discover, that I just don't know what I don't know.

There is one CTF challenge that I haven't completed yet. It's 20 line html page, no javascript, nothing suspicous. No cookies. It has just form with password input, which sends post request to server. Here's the problem - how do I get the flag (the password)? I can bruteforce it, but it clearly isn't the correct way. I know that the php runs on apache, debian. I've tried getting some files, I've tried going up (../), sql injection, nothing works.

And here's the general problem - what am I missing? What to learn? What should I google? I don't want ideas what I'm missing on this one example - Instead I need some sources where I learn generally about vulnerabilities I can exploit. Some blog, some website, something like this.

Could someone here recommend me some sources where I learn about this? How did you start and what things do you generally check when you face something you have to break into?

Thank you

Right now I dual boot windows 10 and fedora, windows for gaming, fedora for everything else. I'm considering running linux as my only native operating system, and running windows in a virtual machine for gaming. This will be more convenient than restarting my pc every time I want to play a game, and I'll feel better about having windows sandboxed in a VM than running natively on my computer.

To get gaming performance out of a virtual machine, I'm planning to have two gpus. One for linux to use, and one reserved exclusively for the virtual machine.

Have any of you set up a computer like this before? What was your experience like? How was the performance?

I tried to use Gnus to set up some rss feeds about a year ago, and I became more than frustrated: I was actually confused.

So here are a couple questions I don't even understand where to ask or whether they're relevant or being asked in the right way:

Are most newsgroups mirrored? And along those lines, is there one particular newsgroup server that would be sufficient for most users?

Can I post to a newsgroup in the same way I would post to a mailing list: send an email somewhere? Where do I send that?

What even is NNTP? Someone literally sent me the spec for the protocol, but I don't think they actually wanted to be helpful: I felt like they were putting me down and intentionally not answering while giving the appearance of being helpful. Is it actually something I need to understand to use Gnus effectively?

If you're familiar with newsgroups, I would surely appreciate your knowledge.

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.

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!

Hi there,

It looks like codecademy took down their PHP course, which stinks becuase I love, love, love how that site approaches teaching by doing. Any other free resources out there for a do-not-show approach for learning PHP?

Looking to get my feet wet so I'm a little less dangerous when tinkering with my WordPress templates.

Howdy Tildes wizards.

I decided to have a looksy at Stable Diffusion on my local computer (Manjaro, AMD 7500x CPU, 32GB) using Easy Diffusion. I've gotten my head around the basics and grabbed MidJourney V4 LLM, and now I'm learning how to prompt.

So far I've generated some cool cyberpunk cyborg things, landscapes, etc. One of the things I wanted to use Stable Diffusion for is generating silhouettes. Sounds weird, I know, but they're great to use with decal and vinyl printing for my wife's business.

Any ideas on ways to do silhouette generation?

Next is, what's good to read to learn about model types and what all of the settings really do?

I'm ordering a GPU (3060) to improve the horrendous render times, so don't worry about the under powered rig, I'm still in toy mode.

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 will shortly be travelling for work. I do not have the capacity to bring anything other than my work machine. In addition to working every day I would like to: legally stream movies in the evening, work on writing, email friends etc. At home of course I use a separate laptop for this but in this case I won't have that option. Any thoughts on how best to achieve a separation of concerns while travelling? How do people on Tildes manage this case?

p.s I know in a best case scenario it's not ideal, hence my behaviour at home, I just need a working method for this particular case.

So... a friend did this for me a long time ago, but I've replaced my computer since then, and I don't know how to do it for myself.

I know how to find the MAME executable. I don't know whether I need to download the .exe file or the .zip file, but I assume the .exe file is the better option.

I know how to run an executable file, and I'm assuming it installs itself.

I know how to find a copy of the antique video game I want.

However...

The .zip file I download for the game contains a lot of files with names like "a26-13.109" - and I don't know what I'm supposed to do with those, to get them inside the MAME and make the game playable.

I'm running Windows 10 on a 64-bit operating system, if that's relevant.

Is anyone feeling charitable and willing to help someone who's not computer literate to do this?

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.

Hi
With this LITE site ---> https://lite.duckduckgo.com/lite/
There isn't the Dark Theme that's available for original duckduckgo site.

I found a "My filters" rule on the web.

Add these two lines to My filters

lite.duckduckgo.com##html:style(color: rgb(141, 141, 141) !important; background: none repeat scroll 0 0 rgb(48, 48, 48) !important; font-family: 'Helvetica Neue','Segoe UI', Arial, sans-serif;)

lite.duckduckgo.com##a:style(color: rgb(201, 201, 201) !important;)

When the rule is used the search homepage looks reasonable.
And the search results...
The black background is not very black, not as black as Tildes black theme.
I can live with that.

But the red text under each result is very muddy.
Can that be improved?
Make it brighter Crimson or even Orange would look better.

I have to preface this question with a disclaimer that I am an eager learner of Linux and servers in general, but I'm still a beginner and often run into roadblocks.

Current setup:

• Raspberry Pi 3 with Adguard Home acting as primary DNS
• unRAID server with Adguard Home acting as secondary DNS
• About a dozen other containers running on same server
• DHCP is handled by my router

Goal:

• provide local DNS names for the containers running in unRAID so I don't have to enter IP:Port (e.g, calibre.local) which also has the side benefit saving the various username/password combos into Bitwarden with an actual domain attached to it instead of 14 occurrences of 192.168.x.x

Additional info:

I had PiHole running on the Pi before as the primary and only DNS previously. And I seem to recall you could put IP:Port as a custom DNS and have it resolve. AGH does have a feature for DNS Rewrites but it does not allow for port numbers, IPs only. I switched to AGH because it seems to be more effective at blocking ads, which is likely more a function of the provided DNS blocklists out of the box as opposed to what I was doing in Pihole. I would prefer to stick with AGH for adblocking/DNS if possible.

I looked into just modifying host files on the main computers I touch these apps from, but again, can't include port. What is a good solution for this? Preferably something approachable for a newb like me.

Current Library: built in sqlite
Current db: sqlite (but will have access to Snowflake soon for option 1 below)

Wondering if anyone here has some advise or a good place to learn about dealing with databases with Python. I know SQL fairly well for pulling data and simple updates, but running into potential performance issues the way I've been doing it. Here are 2 examples.

1. Dealing with Pandas dataframes. I'm doing some reconciliation between a couple of different datasources. I do not have a primary key to work with. I have some very specific matching criteria to determine a match (5 columns specifically - customer, date, contract, product, quantity). The matching process is all built within Python. Is there a good way to do the database commits with updates/inserts en masse vs. line by line? I've looked into upsert (or inserts with clause to update with existing data), but pretty much all examples I've seen rely on primary keys (which I don't have since the data has 5 columns I'm matching on).

2. Dealing with JSON files which have multiple layers of related data. My database is built in such a way that I have a table for header information, line level detail, then third level with specific references assigned to the line level detail. As with a lot of transactional type databases there can be multiple references per line, multiple lines per header. I'm currently looping through the JSON file starting with the header information to create the primary key, then going to the line level detail to create a primary key for the line, but also include the foreign key for the header and also with the reference data. Before inserting I'm doing a lookup to see if the data already exists and then updating if it does or inserting a new record if it doesn't. This works fine, but is slow taking several seconds for maybe 100 inserts in total. While not a big deal since it's for a low volume of sales. I'd rather learn best practice and do this properly with commits/transactions vs inserting an updating each record individually within the ability to rollback should an error occur.

I have the following on my fonts.conf

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <alias>
    <family>system-ui</family>
    <prefer>
      <family>FreeSans</family>
    </prefer>
  </alias>
</fontconfig>

But when websites use font-family: system-ui firefox just ignores this and uses Cantarell anyway, which I don't even know where it is getting it from. (Not Firefox font preferences).

Any idea how to make firefox respect my fonts.conf?

This is Linux with i3.

I have a personal website, and while I don't mind it showing up in SERPs for DuckDuckGo, Bing, etc. I do not want it showing up on Google at all.

Google doesn't send traffic my way, I pay for my site out of my salary from my day job instead of running ads, and preventing Google from indexing my site seems like the best form of nonviolent direct action I can take to protest their continuing dominance and their "embrace, extend, and extinguish" campaign against the Web.

I figure the easiest way to do this is to add the following to my site's .htaccess file since I don't have access to the server config file:

X-Robots-Tag: googlebot: none, noarchive, nosnippet, notranslate, noimageindex

Are there any downsides that I should know about besides not showing up in Google results?

I recently started having an issue on my windows machine with folder permissions. The start menu folder suddenly became inaccessible to any program that tried to create a shortcut there. I worked around it by just taking ownership.

Now I'm facing a much worse problem where many operations that require admin elevation suddenly doesn't work even after a UAC prompt. This has really become a problem now that I want to install wsl on this machine. Running wsl --install just returns the wsl usage info and wsl --update throws a UAC prompt, but fails saying "The requested operation requires elevation" even while logged into the built in Administrator windows account.

Normal programs can still use admin elevation (mostly), but everything that windows prompts for behaves as if I'm a regular user despite still giving and accepting a UAC prompt. The Microsoft Store has also seemingly lost the ability to update or repair itself also so that's probably related.

I've tried all the usual stuff with /DISM, /sfc, every Microsoft troubleshooter. They found no issues. Creating a new admin account lets me create the account but then it inherits the same issues. I can't even gain admin elevation in safe mode. I'm really at a loss. I don't want to have to do a system refresh because it takes so much time to get set back up, but at this point I don't know what else to do.

Has anyone else ever encountered an issue like this? I've tried searching for this and just end up on a bunch of identical 'help' pages telling me to right click -> run as admin or the generic Microsoft employee pointing me to reinstall again.

Windows version 10.0.19045 Build 19045 in case that matters

Edit: I never did find a solid reason why this was happening. It wasn't my university Maya account. While reinstalling windows on a freshly formatted drive I kept getting errors that eventually led me to discoving my ram was going bad. Got it replaced and installed windows just fine. I have to assume the problem started because of memory errors. Thanks for the suggestions everyone.

I cannot push nor pull to/from my local repo to/from my remote. I get the message "Your branch and 'origin/main' have diverged", etc.

I will be able to fix it, I'm already in the process of refreshing my memory on how to rebase this cleanly.

But ... I am the only person working on this. I have only one local and one central/remote repository. And I never made a branch.

It's just me, working on one computer, right here ... make a few commits locally, then push 'em ... make a few commits locally, then push 'em. That is my entire workflow.

How in the hell did I end up with "my branch" (???) and the origin/main branch being in conflict with each other?

Any Git gurus care to take a stab at this?

Thanks in advance.

Edit, more info:

I am guessing here, but for awhile I was working in a VM on my local machine ... but Android SDK is too much of a resource hog, so I committed and pushed everything on the VM, shut it down, and then pulled latest down to my actual machine ... or at least, that's how I remember it.

My working theory is that, somehow, I screwed up that "switching between machines" process, although, so far, no clue as to how/why I did.

Theory #2 is that Android SDK did something sneaky/stupid behind the scenes -- my last several commits have been done through the Android Studio IDE, not directly in the terminal.

Last Edit:

D'oh!

Found it. I made a couple of "quick changes" to the project's README.md file directly in the remote forge, and that's what screwed me up.

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 knowledge of the basic concepts of programming in general and html and some very basic knowledge of javascript, but this specific task is proving a little beyond me. I'm actually using tampermonkey, in case that matters.

www.bricklink.com is a site to buy Lego from private sellers. By default, when looking at a shop's listing of items, it shows 25 per page. I would like to automatically switch to 100 per page every time.

Here's a randomly selected store page (no affiliation) at the default 25 per page:

https://store.bricklink.com/TheBricky#/shop?o={"itemType":"P","catID":"18","showHomeItems":0}

Now, same page set to display 100 per page. Note how "pgSize" is added to the url but doesn't appear by default:

https://store.bricklink.com/TheBricky#/shop?o={"pgSize":100,"itemType":"P","catID":"18","showHomeItems":0}

What I would like is for pgSize to be set to 100 only IF

"shop" appears in the url

AND

"pgSize" does not appear in the url OR "pgSize" does appear in the url but does not equal 100.

Since Bricklink remembers pgSize per shop page per session, once pgSize is set to 100 for a particular shop greasemonkey doesn't need to do anything. Intercepting the url before the page loads would be nice but unnecessary since loading is fast and I'm not worried about bandwidth.

I tried making this but wasn't sure how to input what I'm trying to test for in the url. Of course now that I've thought about it some more it seems the task is more probably difficult than I thought it would be at first. Any help would be appreciated.

EDIT: This comment below seems to be working, although the way Bricklink makes their urls feels funky at times.

Hi,

There's a certain site which hosts media files and has a player that depends on a lot of third-party resources to play, while browsers have native support for those file types. Those 3rd-party resources are often blocked by ad blockers and I have no desire to white-list them. I would like to extract the direct link to the media file and make it playable on my custom web page.

The link to the media file is present in the page source of each page, always on the same line. It's not anchored in HTML but present in the JavaScript for the player, like so:

    $(document).ready(function(){
      $("#jquery_jplayer_1").jPlayer({
        ready: function () {
          $(this).jPlayer("setMedia", {
            [ext]: "https://[domain]/[filename.ext]"
          });
        },

In this example it's on line #5. [ext] = the file extension.

I want to build the following:

• A web page with a form with a single input field meant to receive links from that specific file host
• [Something] that extracts the file link from the source of the host's page
• Present the linked file as playable in an embedded native player

So far I've managed to create a form with an input box and a submit button, but it doesn't do anything yet. What is the best way to build the actual functionality? I know HTML/CSS. I have some rudimentary understanding of JavaScript/jQuery and Python3, so those would be my preferred tools.

For those worried about piracy: The files in question are not copyrighted and I'm not looking to make copies. I just want to make them playable. This is for personal use.

Thank you for reading this far. Any and all advice is welcome!

I hope I’m posting this in the correct place. I’ve been having a disagreement with someone over the abilities of hackers. I kinda hope Deimorz pops in because he wrote automod.

I said that the only way for someone to gain access to a subreddit to make changes is if they steal a moderator’s account password or they are added to the mod team. The person I’m having a disagreement with believes that adding text to the wiki for users to view (like the extensive wiki r/skincareaddiction has) would make it easier for hackers to insert malicious code in order to gain access to the sub. This person also mentioned being able to change the subreddit through browser tools. She insists the sidebar and wiki are potential access points for scripting attacks. Automod just so happens to be enabled which is why I mentioned Deimorz.

I’m not an IT professional. My brothers currently are which helped me learn most of what I know. I’ve supplemented that over the years with whatever info I came across online. What she’s saying sounds like crazy town to me. But since I’m not a hacker, is there a way to use the sidebar or wiki area to hack into a subreddit?

Thanks in advance to anyone who pities me by providing a detailed answer to this thinly veiled request to help me win an internet argument 🙇🏾‍♀️.

Me and my friend arrive at an arbitrary place, we have access to a network from there. Now, we want to share a file and the network connection is all we have. The challenge: make the file go from my device to my friends device in a pure p2p setting. If you know, for sure, that incoming connections are allowed this is very simple but here i want to explore which solutions exist that do not assume this.

Assumptions:

• Same network altough possibly different access points (one might be wired and the other wireless)
• We have no prior knowledge about the network, incoming traffic might be blocked (outgoing isn't for sure)
• No extra machines can aid in the transaction (no hole punching etc)
• Should work reliably for any kind of device that you have free -- as in freedom -- control over. that is PCs, android phones/tablets and macs. most of Apple's other hardware can be excluded because they don't allow for anything anyway.
• hard mode: We are both digitally illiterate

Goal:

• Send a file, p2p, from one party to another.

Me (MSc cs) and my friend (PhD cs) tried to do this last week. And it appears to be among the hardest problems in CS. I would like to discuss this and hear which solutions you might have for this problem.

Edits:

1. this is not an assignment
2. Added some specifics to the assumption set
3. we're looking for practical solutions here.
4. more specs

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'm going to be flashing a custom ROM on my Nexus 5X device, and I was just curious if I'm understanding all the components involved. I currently have CopperheadOS on my device, but that ROM may be dead based on current events. I'm not switching because of this news, but mainly because I just want to try something else for the hell of it. I think I'm going to make the switch to Lineage, but there are way more options involved versus flashing CopperheadOS.

It seems the main components to consider when flashing are the following:

• The ROM itself (CopperheadOS, Lineage, PureNexus, etc.)
• The custom recovery (TWRP, etc.)
• The kernel (ElementalX, Franco, etc.)
• root (magisk, etc.)
• Play Services (OpenGApps, etc.)

CopperheadOS was kind of it's own package, so I didn't have to consider all of these other options.

My understanding is the minimum decisions I need to make if I want a custom ROM, is picking the ROM itself, and a custom recovery. In my case I'm going for LineageOS and TWRP.

Choosing a custom kernel seems to be optional. I think I might go with Franco on this one based on the little research I've done. But to flash a custom kernel, I think I need root, right? So now I'll need to get root access which requires another tool. I was going to go with Magisk based on not much. Just seems to be common. So that's 4 main things there. The ROM (LineageOS), the recovery (TWRP), the kernel (Franco), and root (Magisk). I personally don't want any Google services on my device, so I'm fine with skipping that part. I currently don't have any installed, and I'm doing fine without them.

So does my view on this seem correct? Are all the things I mentioned necessary for what I want to do? If I want LineageOS then I need a custom recovery right? If I want a custom kernel, then I need root which requires a separate tool, right? Just making sure I'm not doing more than I need to if I decided to go through with this. As a side convo, please recommend whatever ROMs, kernels, or root tools that you want. I have a Nexus 5X, and I'm hoping it doesn't bootloop after I'm done doing all this flashing =)

Pseudo because upgrading some of the parts might have a knock-on effect for other parts. Might end up leading to an upgrade of the whole system, idk. So here's a list of parts that I've already acquired. I was originally going to use some of them to fill out the Framework laptop that I pre-ordered... but I had an expensive couple of months earlier this year and figured I could wait on it. :(

Now here's what I have in my tower currently.

I'm looking to keep the tower at the very least and reuse it for new components. Right now, I know that the mobo will absolutely need to be replaced IF I'm throwing the ryzen chip in. And with knock-on effect, probably the psu as well since these components are drawing more power. The goal is to get a solid 60 fps on Helldivers (which I can't do at the moment, even on the lowest graphical settings) since it's the most intensive game that I play. With this goal in mind, does it make sense to start using the components I have from the first list, or might it be cheaper to keep them for the framework and get older (still compatible) parts that would fit right in to the system as it stands?

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.

Hello everyone. I consider myself fairly competent when it comes to my work with LaTeX, but as everyone who uses it knows, it is definetely strange sometimes. And right now I have a problem which just irks me in the wrong ways:

I use XeTeX and a number of custom fonts for my documents, but when writing mathematical formulas I found out that the font I set for Greek letters (Gentium Plus) is used for letter commands like \alpha, \Alpha, ... but not for commands like \sum, \prod. As you can see in this example here. You can see XeTeX defaults to Computer Modern.

I've looked all over the net for solutions but I can't find one. I'm using mathspec, amsmath, amsfonts, amssymb as my font related packages and I set my fonts like this:

\setmainfont{Charis SIL}
\setsansfont{Helvetica Now Display}
\setmonofont[Scale=MatchLowercase]{Fira Code Retina}
\setmathfont(Digits,Latin){Charis SIL}
\setmathfont(Greek){Gentium Plus}

I feel like I'm going insane not solving this problem. Should you require it, my entire LaTeX template is here on Github. Please help, thank you.

Consider the strange case of this reddit preview page for example:

https://preview.redd.it/uhomipyb8kp71.jpg?width=575&auto=webp&v=enabled&s=b0e044ddd8a83774e0453cb7607ef681444c4c37

If you inspect the primary <img> element on the page, you'll find its src attribute not pointing to any image file but (behold!) that link itself!

Through this mechanism, they've effectively hidden the direct link to that image, isn't it? How is this even possible? Is this a new phenomenon or way in web development?

This is a total longshot. I moved away from a WD My Cloud EX4100 w/ 3x WD Reds to a new box. I bought two more drives for the new one to make the move easier.

After the move I took the drives out to format them only to find that each 4TB drive shows a partition of 1.8TB on any other system (diskpart with W10 LTSC, Disk Utility MacOS, and GParted with Ubuntu.) Inside the EX4100 the drives show their full capacity.. and I just don't get it.

I reached out to their support, but I don't expect much of a response.

Anybody have any idea why the heck this could be happening? This seems crazy. I don't mind buying more drives, but it seems like a waste when I've got 12TB just sitting there.

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 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.

Trying to get a sense on how the networking would go down?

If I had one public IP address and say 4 Docker containers on the host, how would the SSH connections work? Would I have to reserve ports for each container?

So, I'm using Arch i3wm. I have multiple copies of my /home/username (I am the sole user), and I have a "Spare" drive with media, games, and other goodies, some of which are also stored on partitions on the m.2 in question, but they have backups.

And the reason I ask this question is because while I've had my m.2 fail at the end of '21 (I didn't even know that was a thing, but it barely lasted a year, and things are acting shoddy now... though the original failed without a warning), I just bought a second m.2 for my games. I guess I could swap most of the whole thing over, but I know the boot partition is easier just rebuilt from scratch... which I had to do last week.

Ultimately, what's making me suspicious is when I upgraded to the new drive and unplugged all my non-m.2 satas, I also added some memory and a new power supply. But then after the upgrade (Monday of last week, so the 5th), the system wouldn't boot up. I used a usb to troubleshoot and my /boot partition was apparently no gouda. I redid that, and everything was fine... until this week. Then my new Games partition (basically the new drive) failed fsck and it got stuck in a boot loop on Tuesday. I could boot emergency to root, but not skip the fsck and keep the Games disk auto mounted (I know I changed something to randomize fsck on bootup, but that's something I'm still kinda looking into how I managed...), so I just removed it from my fstab and it booted fine. For two times. I just manually mounted the drive, all was great, then my SO sent me a screenshot today while I was at work stating that my / partition (on the older m.2) apparently rebooted because it bypassed my screen lock, and was stating EXT4-fs error, reading directory lblock:0 and whatnot.

So, that's my history on what's going on, and if anyone can offer any advice [mostly] on the backup stuff, though as I said, /home and the important tangible stuff is saved, but if you also have any input on something more than I suspect the drive is failing (since the /boot partition and now the / partition are crapping out), please feel free to share.

(Also, thanks for letting me in. This is what I'd typically post on reddit and probably have to repost 10 times depending on the sub to get the right keywords and tags and yes, I already searched the internet but my search will not match yours... sigh)
