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.

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!

I don't need answers so much as an idea of where to start.

Essentially, I have a Google Sheet that uses importjson.gs to pull from the following APIs

• OMDB (IMDB)
• TheMovieDB
• TVMaze

I also use another script to scrape Letterboxd for ratings.

This works well, but sometimes it'll time out or I'll hit urlFetch limits that Google has in place.

Basically, I'd like to have a text file (input.txt) where I pop in a bunch of titles and year or IMDB IDs, then the script runs and pulls set endpoints from all of these, outputting everything on one line (a pipe as a delimiter.)

My thinking is that I can then pull that info a sheet and run all of the formatting, basic math, and whatever else so it suits my Sheet.

I have a feeling I'll be using requests for the JSON and beautifulsoup for letterboxd -- or maybe a module.

Can anyone point me in the right direction? I don't think it'll be too difficult and should work well for a first python project.

I still mainly use Windows, although I've dual-booted Linux a few times and I have Linux Mint on an old laptop right now. One thing I've never understood about Linux is all the different distributions - their different reputations and why they have them. What is the mechanical difference between using one distribution of Linux and another? Or are the differences usually not mechanical?

For example, Ubuntu and Debian seem to be large families, meaning that a lot of other distributions are based on them (using packages built for them in their package managers at least) as well as being popular distros on their own. But what's different between the two of them, and between each and the other distros based on them? (and what's similar? I gather they all use the Linux kernel at least!)

I also know that people are quite opinionated on their choice of distro, I wondered what reasons people had for their choice. What things are easier or harder for you in your distro of choice? Is it mainly day-to-day tasks that are important or more how the OS works underneath? How much difference does your preferred distro make?

For myself, I've only used Kubuntu (though not much) and Linux Mint, which was mainly for UI reasons, and particularly for the latter, ease of use for someone used to Windows (at least that was what I found years ago when I first looked into it).

Though I doubt I'll ever fully move away from Windows I would like / need to have access to a Linux OS, so maybe this will help me to know what is important to look for. But I also hope it'll be a useful and interesting discussion topic. Also, there are some previous discussions on the latter question so I'd be more interested in learning about the main topic.

also, please do add more tags

I see some people using NixOs on their servers. I would like to try it out to self host some services and learn about NixOs.

I use hetzner and they have an NixOs iso available so I can just use that to install NixOs. But how do people manage remote instances of NixOs? They would just use ansible or something like it, to run nix on the host, or is there a better way?

Thanks

I've just read a journal from someone on another site saying that they wished there was a blacklisting system which stopped them seeing submissions from, to or about certain other users in their feed, as it is potentially trauma-inducing for them to log in and keep seeing them come up. I assume that the person looking for this blacklist isn't realistically able to just leave the site, because it's the most populous of its kind and serves as an art portfolio or source of income.

Is this, or something like it, actually possible to do with custom ad-blocker rules, or do they need to just wait for the site's admins to get around to it?

I'm attempting to provision two mirror staging and production environments for a future SaaS application that we're close to launching as a company, and I'd like to get some feedback on the provisioning script I've created that takes a default VPS from our hosting provider, DigitalOcean, and readies it for being a secure hosting environment for our application instance (which runs inside Docker, and persists data to an unrelated managed database).

I'm sticking with a simple infrastructure architecture at the moment: A single VPS which runs both nginx and the application instance inside a containerised docker service as mentioned earlier. There's no load balancers or server duplication at this point. @Emerald_Knight very kindly provided me in the Tildes Discord with some overall guidance about what to aim for when configuring a server (limit damage as best as possible, limit access when an attack occurs)—so I've tried to be thoughtful and integrate that paradigm where possible (disabling root login, etc).

I’m not a DevOps or sysadmin-oriented person by trade—I stick to programming most of the time—but this role falls to me as the technical person in this business; so the last few days has been a lot of reading and readying. I’ll run through the provisioning flow step by step. Oh, and for reference, Ubuntu 20.04 LTS.

First step is self-explanatory.

#!/bin/sh

# Name of the user to create and grant privileges to.
USERNAME_OF_ACCOUNT=

sudo apt-get -qq update
sudo apt install -qq --yes nginx
sudo systemctl restart nginx

Next, create my sudo user, add them to the groups needed, require a password change on first login, then copy across any provided authorised keys from the root user which you can configure to be seeded to the VPS in the DigitalOcean management console.

useradd --create-home --shell "/bin/bash" --groups sudo,www-data "${USERNAME_OF_ACCOUNT}"
passwd --delete $USERNAME_OF_ACCOUNT
chage --lastday 0 $USERNAME_OF_ACCOUNT

HOME_DIR="$(eval echo ~${USERNAME_OF_ACCOUNT})"
mkdir --parents "${HOME_DIR}/.ssh"
cp /root/.ssh/authorized_keys "${HOME_DIR}/.ssh"

chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
chown --recursive "${USERNAME_OF_ACCOUNT}":"${USERNAME_OF_ACCOUNT}" "${HOME_DIR}/.ssh"

sudo chmod 775 -R /var/www
sudo chown -R $USERNAME_OF_ACCOUNT /var/www
rm -rf /var/www/html

Installation of docker, and run it as a service, ensure the created user is added to the docker group.

sudo apt-get install -qq --yes \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88

sudo add-apt-repository --yes \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

sudo apt-get -qq update
sudo apt install -qq --yes docker-ce docker-ce-cli containerd.io

# Only add a group if it does not exist
sudo getent group docker || sudo groupadd docker
sudo usermod -aG docker $USERNAME_OF_ACCOUNT

# Enable docker
sudo systemctl enable docker

sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version

Disable root logins and any form of password-based authentication by altering sshd_config.

sed -i '/^PermitRootLogin/s/yes/no/' /etc/ssh/sshd_config
sed -i '/^PasswordAuthentication/s/yes/no/' /etc/ssh/sshd_config
sed -i '/^ChallengeResponseAuthentication/s/yes/no/' /etc/ssh/sshd_config

Configure the firewall and fail2ban.

sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow ssh
sudo ufw allow http
sudo ufw allow https
sudo ufw reload
sudo ufw --force enable && sudo ufw status verbose

sudo apt-get -qq install --yes fail2ban
sudo systemctl enable fail2ban
sudo systemctl start fail2ban

Swapfiles.

sudo fallocate -l 1G /swapfile && ls -lh /swapfile
sudo chmod 0600 /swapfile && ls -lh /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile && sudo swapon --show
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab

Unattended updates, and restart the ssh daemon.

sudo apt install -qq unattended-upgrades
sudo systemctl restart ssh

Some questions

You can assume these questions are cost-benefit focused, i.e. is it worth my time to investigate this, versus something else that may have better gains given my limited time.

1. Obviously, any critiques of the above provisioning process are appreciated—both on the micro level of criticising particular lines, or zooming out and saying “well why don’t you do this instead…”. I can’t know what I don’t know.

2. Is it worth investigating tools such as ss or lynis (https://github.com/CISOfy/lynis) to perform server auditing? I don’t have to meet any compliance requirements at this point.

3. Do I get any meaningful increase in security by implementing 2FA on login here using google authenticator? As far as I can see, as long as I'm using best practices to actually ssh into our boxes, then the likeliest risk profile for unwanted access probably isn’t via the authentication mechanism I use personally to access my servers.

4. Am I missing anything here? Beyond the provisioning script itself, I adhere to best practices around storing and generating passwords and ssh keys.

Some notes and comments

1. Eventually I'll use the hosting provider's API to spin up and spin down VPS's on the fly via a custom management application, which gives me an opportunity to programmatically execute the provisioning script above and run some over pre- and post-provisioning things, like deployment of the application and so forth.

2. Usage alerts and monitoring is configured within DigitalOcean's console, and alerts are sent to our business' Slack for me to action as needed. Currently, I’m settling on the following alerts:
   1. Server CPU utilisation greater than 80% for 5 minutes.
   2. Server memory usage greater than 80% for 5 minutes.
   3. I’m also looking at setting up daily fail2ban status alerts if needed.

Hi! I've heard tilderinos talking about the gemini-verse on some other posts; I tried it out this evening and it honestly felt strange browsing in terminal and even stranger navigating the web without search engines. I was wondering if anyone had a gentler introduction than the official site? I feel like I've got a ship, but no map to this new verse.

Suppose I am trying to iteratively produce a completed image from some subset using a combination of convolutional/DNN methods. What Image norm is best?

The natural (for me) norm to ascribe to an image is to take the bitmap as a vector with L₂. If the input image is anime or something else, the uniform coloring makes this very likely to be a good fit in a low dimension - that is: no overfitting.

However: pictures of fur. Given a small square, the AI, set to extrapolate more fur from that single image, should be expected to get that stuff right next to the given subimage right, but further away, i want it to get the texture right, not the exact representation. So, if the AI shifts the fur far away from the image left by just the right amount, it could get an incredibly poor score.

If I were to use the naive L₂ norm directly, I would be guaranteed to overfit, and you can see this with some of the demo algorithms for image generation around the web. Now, the answer to this is probably to use a fourier or a wavelet transform and then take the L_N norm over the transformed space instead (correct me if I'm wrong.)

However, we get to the most complex class: images with different textures in them. In this case, I have a problem. Wavelet-type transforms don't behave well with discrete boundaries, while pixel-by-pixel methods don't do well with the textured parts of images. Is there a good method of determining image similarity for these cases?

More philosophically, what is the mathematical notion of similarity that our eye picks out? Any pointers or suggestions are appreciated. This is the last of two issues I have with a design I built for a Sparse NN.

Edit: For those interested, here is an example, notice how the predictions tend to blur details

Last Thursday, at my workplace, we rolled out a software upgrade across the company. The server side was upgraded overnight to ensure there was minimal downtime, and we had instructions for users posted on our Intranet (pinned to the top for the next 4 days), on exactly what they needed to do to run the upgrade on their PCs and ensure everything was working correctly.

The instructions were written with the help of my 4-year-old to ensure it was clear enough for anyone to read and follow along.

I still received at least 40 messages and emails from people complaining the upgrade didn't work or that certain Outlook plugins are now missing (which was covered in the instructions).

My question is, has anyone found a good way to ensure people follow instructions, or the best way to ensure that your instructions are easy to understand and follow along with?

It is very frustrating to take the time to ensure things go smoothly and write what even my 4-year-old thought was clear instruction, and still have a third of the company not be able to figure it out?

This is not meant to be mean hearted in any way, I genuinely would like some advice or tips on how I can improve on this the next time around.

Thanks.

I'm working on an application that allows a user to view playlists belonging to a particular radio show and stream/download/favourite the tracks in them. It has 4 core entities: User, Show, Playlist and Track.

• Each show has multiple playlists (one-to-many)
• Each playlist has multiple tracks (one-to-many)

To be able to reference a playlist belonging to a particular show. I gave those playlists the same uuid as the show they belong to. A few questions though.

1. Is this the right/best way to associate data?
2. As a track could potentially belong to multiple playlists, I can't take the same approach as I do for (show/playlist) How would be best to handle this? Ideally I would like to have a single "Track" table containing all tracks for all playlists.

For any experienced database designers out there, how would you structure this data? What would you consider in designing the schema and why? If I did go with 4 tables only, presumably there would be performance implications given the potential amount of data in any one of those tables, particularly tracks. If that is the case, how best to structure this kind of thing with performance in mind? Thanks in advance for any help :)

For reference, in case it's of importance, I'm using sqlite3.

Hey everyone,

I've been programming for some time now but notice without any formalized education in CS I often get lost in the weeds when it comes to developing larger applications. I'm familiar with the principles of TDD and SOLID - which have helped with maintainability - however still feel that I'm lacking in the ability to architect a properly structured system. As an example, I'm currently developing a flask REST API for a website (just for learning purposes). This involves parsing a html response and serializing the result as JSON. I'm still quite unclear as to structuring this sort of thing. If any more experienced developers could point me in the right direction/offer up their opinion I'd be very appreciative. Currently I have something like this (based - I hope correctly? - on uncle bob's clean architecture).

Firstly, I'm defining the domain model. i.e the structure of the API response. Then, from outside in.

1. Infrastructure (Flask): User makes request via interface (in my case a request to some endpoint)
2. Adapters: request object checks if the request is valid (on the way back it checks if the response is valid) - Is this layer only for error handling?
3. Repository: I'm struggling a bit here, AFAIUI this layer is traditionally a database. In my case however, where the request is valid, is this where I should handle the networking layer? i.e all the requests to return the website source? I'm also confused given at this stage I should be returning the relevant domain model, like an ORM, but as my data is unstructured, in order to do this I need to transform the response first. Where would it be best to handle this?
4. Use Cases: Here I transform the domain model depending on the request. For example, filter all objects by id. Have I understood this correctly?
5. Serializers: Encode the domain model as JSON to return from flask route.

If you got this far, thanks so much for reading. I really hope to hear the opinions of more experienced devs who can steer me in the right direction/correct me should I have misunderstood anything.

I am a fullstack developer that spends a good portion of my time building out complex User Interfaces, and the rest building out back-ends for that software. In my opinion the current method that my company uses for a designer to developer hand off is a bit lacking in efficiency.

The current method is usually a designer will provide a developer with a Photoshop (or very occasionally an Illustrator) file containing the entire applications design. It is then up to the developer to export assets (both quick exporting things as pngs, going through and separating shadows from assets, or creating assets from the layers provided) and dig through the file to determine fonts and placement of items.

Is it a common expectation that a developer should be spending a good chunk of time in Adobe on asset manipulation?

Additionally does anyone have any process or program suggestions that may make life easier?

I read the AskReddit thread on "What costs less than $100 that changed your life?" (link unavailable since I'm at work) but someone responded "SQL" - jobs just open up that make a ton of money.

I did a cursory search on Indeed and holy moly they were right -- SQL jobs get easily 2x what I make now. I'm pretty good at Excel and that sort of thinking, so I was thinking I'd try taking a class.

Do yall have any recommendations as to a good course to take in SQL, preferably online, preferably free or cheap? I'm willing to pay a bit if it'll mean I can make a lot more, but I'm currently not making a ton, haha.

Any responses welcome, including ideas as to how to break into like, tech-oriented fields as well.

I've been thinking on and off about packaging up a few simple Python utilities I've written to stick up on Github for people to use if they want, but, every time I go to check out how one goes about managing dependencies and all that for a project, I run into a whole wall of options. Does anyone better versed in all of this have any recommendations for me?

I have two computers (a desktop and a laptop) that broke down just before my city entered a lockdown. Being able to assemble and fix my own computer hardware is something I have always wanted to do, and if I knew that I would probably not be using a borrowed Macbook Air right now.

I have no immediate need to provide any maintenance services, nor do I require a primer in electronics or anything too advanced. Just enough to know how to assemble and disassemble a machine, identify and fix the most obvious issues without breaking anything.

I tend to learn better from sequential and structure learning materials, preferably in text/images form. But videos are also welcomed. I know the names of the things and what they are, but I don't really know how to put things together in practice.

Suggestions? :)

I have basic notions of HTML and CSS, but nearly zero JS knowledge. I can perform simple customizations and I know how to follow instructions.

It is not my intention to create anything from scratch (so the platform should have plenty of free themes), nor do I want to become a webdev or webdesigner. This is not a technical project for me, my main concern is the content.

I currently have a blog that uses Wordpress with a purchased theme. It's good enough, but a bit slow to load. Besides, simpler platforms might be easier to understand and manipulate.

This alternative would also need to be FOSS and easy to self-host.

As a plus, it would be awesome if I could manage the blog/website from within Emacs/Org Mode.

Any ideas?

I have a large VirtualBox VM on an external HDD. The HDD fails the S.M.A.R.T. test. The VM still works fine, but any regular attempt to copy the VM files over to a healthy drive fails ... there is clearly already something corrupt in the VM's virtual HDD, although it is not (apparently? yet?) affecting the functionality of the actual VM.

Any suggestions on how to save the VM? Linux Mint Guest OS, Pop_OS (Ubuntu) Host. The VM is nearly 800 GB. Both regular copy and rsync fail.

Thanks,
Eric

PS: (and perhaps I should have led with this, but...) is it okay to ask these kinds of specific, technical, "help me with my tech-stuff" questions here on Tildes?

Update to the update ... moved update info into a comment ... will keep my progress updated in that primary comment.

Danke, y gracias to all

I'm looking for some feedback on a feasible mechanism for structuring a few API endpoints where a purely RFC-spec compliant REST API wouldn't suffice.

I have an endpoint which returns $child entries for a $parent resource, let's call it: /api/parent/:parentId/children. There could be anywhere from a dozen to several hundred children returned from this call. From here, a child entity is related to a single userOrganization, which itself is a pivoting entity on a single user. The relationship between a child and user is not strictly transitive, but can each child only has one userOrganization which only has one user, so it is trivial to reach a user from a child resource.

Given this, the data I need for the particular request involves retrieving all user's for a parent. The obvious, and incorrect solution to the problem is to make the request mentioned above, and then iterate through and make an API request to retrieve each user. This is less than very good as this would obviously be up to several hundred API calls.

There's a few more scalable solutions that could solve this problem, so any input on these ideas is great; but if you have a better proposal that also works, I'm keen to explore that!

Include user relationships in the call by default.

This certainly does solve the problem, but it's also pumping down a load of data I don't necessarily need. This would probably 2x the amount of bytes travelling along the wire, and in 8 out of 10 calls, that extra data isn't needed.

Have a separate /api/parent/:parentId/users call.

Another option that partially solves the issue: I need data from both the child and the user to format this view, so I'd still need to make the initial call I documented earlier. Semantically, it feels a bit odd to have this as a resource because I don't consider a user to be nested under a parent in terms of database topology.

Keep the original call, but add a query parameter to fetch the extra data

This comes across as the 'least worst' idea objectively, in terms of flexibility and design. Through the addition of the query parameter, you could optionally retrieve the relationship's data. This seems brittle and doesn't scale well to other endpoints where it could be useful though.

Utilize a Stripe expands-style query parameter.

Stripe implements the ability to retrieve all related records from an API endpoint by specifying the relations as strings. This is essentially the same as the above answer, but is scaled to all available API endpoints. I love this idea, but implementing it in a secure way seems fraught with disaster. For example, this is a multi-tenancied application, and it would be trivial to request userOrganization.user.organizations.users. This would retrieve all other organisations for the user, and their users! This is because my implementation of expands simply utilises the ORM of my choice to perform a database join, and of course the database has no knowledge about application tenancy!

Now, I do realise this problem could easily be solved by implementing a GraphQL API server, which I have done in the past, but unfortunately time and workload constraints dictate implementing a GraphQL-based solution is infeasible. As much as I like GraphQL, I'm not as proficient in that area as compared to implementing high quality traditional APIs, and the applications I'm working on at the moment are focusing on choosing boring technology, and not using excessive innovation tokens.

Furthermore, I do consider the conceptuals around REST APIs to be more of an aspirational sliding scale, rather than a well defined physical entity, because let's face it, the majority of popular APIs today aren't REST-compliant, even Stripe's isn't, and it's usually both financially healthier and feature-rich to choose a development path that results in a rough product that can be refined later, than aiming for a perfect initial release. All this said, I don't mind proposals or solutions to my problem that are "good enough". As long as they aren't too hacky! :)

I would like to know more about SaaS companies and enterprise software companies from a business and technology perspective - to know about challenges in the industries, what has been revolutionary, what hasn't, where it is headed, etc. Where would be a good place to start on this?

I'm interested in C or Go, but i'm open to ideas.

I have plenty of sh scripts i created to integrate my tools and system, so i have some experience and i don't want a scripting language like python.

My first plan is to learn the basics of the language and rewrite some of those scripts.

I think my first pick will be a script that uses ffmpeg to convert my flac files to mp3 or opus. I use sndconv -opus/-mp3 and it checks if there are flac files in the folder (i only have full albums), converts and puts in a folder named "$artist - $album".

My long term goal is to make a cli/tui music player like cmus.

UPDATE: i'm having plenty of success with Go right now. I just wrote a basic version of my music conversion script. It's just converting a music i pass as argument to mp3, but i'll keep working on it and adding functionality just to dip my toes in Go. It seems like a good language and i'm having fun!

Thanks for all the answers!

Introduction

I'm a beginner in programming, but a veteran in film and literature. I know that ideas come easy. Any normal person can come up with a good idea in a matter of minutes. The main problem is doing it.

Besides, I couldn't care less if someone does that before me. I'd probably benefit from their program, and even offer to collaborate. I have a bunch of other ideas in the oven anyway.

And I'm humble enough to know that such a niche project would never attract the interest of a mega-corporation anyway.

2. What is CHORES?

CHORES is a short-term task manager. It's meant to organize nothing more than a few hours or less of your tasks. Month, weak or even your entire day are entirely out of its scope.

3. Who is CHORES for?

First and foremost, this app is for my use. But I'm certain there are other people with conditions similar to mine, especially ones with ADHD. I'm also autistic with a compulsive personality, and won't stop until I tinker with every aspect of an object. Not surprisingly, I'm a Linux, i3wm, Emacs and Neovim user. And they're excruciatingly customized.

What I need is not a full-featured a TODO app like Remember The Milk, Todoist or Org Mode. They're too distracting, I end up just playing with the tools. I need something that allows me to track very short term chores. Thinks like brushing my teeth, taking a shower, eating, walking my dog, washing the dishes and making my bed.

That's what I intend to do.

4. What is ADHD

From the United States National Institute of Mental Health:

Attention-deficit/hyperactivity disorder (ADHD) is a disorder marked by an ongoing pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development.

4.1 Warning

Please refrain from suggesting that the ones who use such tools just need to make an effort instead. That's a cliche most people with ADHD and other mental health issues probably heard many times, and by saying that you may cause distress. If you need more information, please refer to the link posted above.

5. Why another "TODO" app?

People with severe ADHD like myself frequently forget what they're doing, and what they should do in the very short term. I'm talking 2, 3 or 5 tasks from now. To give you an idea of how bad it is, right now I have an Emacs Org Mode file with the following tasks:

* Now
** TODO Take Ritalin
** TODO Start chronometer on Ritalin
  - Tells me when the effect wears off
** TODO Take a shower
** TODO Take the laptop to the living room
** TODO Wash the dishes
** TODO Study Python
** TODO Post on Tildes

But Emacs and Org Mode do a lot more than that, and this can be very distracting (right now I'm writing this post because creating another file from my now.org file was way too easy, for example).

Considering that I am the main target audience of this program, any space for tinkering is a dangerous avenue for procrastination.

6. Who is CHORES for

The primary target of this project are people with:

1. ADHD (Attention deficit hyperactivity disorder)
2. similar conditions or personality traits

In sum: if you have extreme difficulty focusing, remembering and fulfilling your tasks in the very short term, you may find this program useful.

7. Who is CHORES not for

The majority of people can concentrate and perform their short-term tasks with a reasonable degree of efficiency. If that is your case, you have little to gain by using CHORES.

8. Features

CHORES is a short-term task manager. It's meant to organize nothing more than a few hours: not your month, weak or even your day.

1. CLI Linux app (Mac, Windows, GUI, and mobile could happen in the future)
2. Hard limit of ten tasks (with the option to reduce)
3. Only the very essential configurations available

• tinkering is a huge time drain for ADHD people
• because of that, the defaults will have to be extremely sensible.

4. Started Stopped status clearly marked by character or highlighting

8.1 What you would be able to do with CHORES:

1. Add up to ten tasks
2. Reorder/Start/Stop/Done these tasks
3. Undo only one operation
4. See only the last ten completed tasks

9. Answer to Possible Questions

9.1 Why Not Keep Using Org Mode? Or maybe Taskwarrior?

Org Mode and Emacs are wonderful tools, but they're also a perfect playground for procrastinators. It simply does too much. Emacs is like a box of legos, and that's the last thing an ADHD person needs when it comes to tracking short-term tasks.

Taskwarrior suffers from the same issue.

9.2 Why Not todo.txt and similar apps?

This may seem crazy, but for a severe ADHD person, even todo.txt gives way too many options and features. It is, after, an actual TODO app. I can add 1000 tasks todo.txt. It has an extensive wiki, projects, tags, context tags, special value tags. You might just say: just don't use these options. But that

9.3 Why not use the extremely minimalist t task manager, by Steve Losh?

I like t very much, and, depending on its license, I'll probably use at least some of its code. But t lacks some features CHORES requires, such as:

1. Limit task amount
2. Add tasks to the bottom (t last tasks randomly, or at least something that seem random to me)
3. Reorder tasks
4. Undo
5. Easily view completed tasks
6. Add Start/Stop status to a task

9.4 Why not pen and paper?

This is a very personal anwer, but here we go:

1. I will lose the paper every 30 minutes
2. I will lose the pen every 30 minutes
3. I will forget to look at the paper, it will probably end up crumpled in my pock
4. Many of my tasks, such as programming and studying, already happen in the computer anyway
5. One of my medications interferes with my motor skills and my handwriting is hard to understand - even for me
6. I like computers. The fact that I like computers makes more likely for me to actually look at the tasks.
7. In the future, I can add alerts. Can't do that with paper

Hi all,

I'm looking for some advice regarding how to set up a basic CI regression / testing suite. This isn't my full time job, but a side project my group at work wants to spin up to... shall we say, give us a more real time monitoring of functionality and performance regressions coming out of the underlying software stack development (long story).

As none of us are particularly automation experts, I was looking for some advice from my fellow Tilderinos. Please forgive me if any of the below is obvious and/or silly.

A few basic requirements I had in mind:

1. Can handle different execution environments: essentially different versions of the software stack, both in docker form and (eventually) via lmod or some other module file approach (e.g., TCL), and sensible handling of a node list.

2. Related to one, supports using the products of builds as execution environments. Ideally we'd like to have a build step compile the stack and install it to a NFS from which we can load it as a module.

3. Simple to add tests. Again, this isn't our full time job -- we mostly want to add a quick bash script / makefile / source code or the like to the tests when we run into an issue and forgot about it.

4. Related. We should be able to store the entire thing as a git repo. I have seen this to some extent with Travis, but my experience with Jenkins was... sub-par (is there a history? Changelog? Any way at all of backing up the test config?).

5. Some sort of post-processing capabilities. At a glance we need to be able to see the top line performance numbers for 20-30 apps over the different build environment. Bonus points if there's a graph showing performance vs build version or the like, but honestly a CSV log file is good enough.

6. Whatever CI software we get has to be able to run this locally. Lots of these are internal only numbers / codes. FOSS prefered.

7. A webui for scheduling runs / visualizing results would be nice, but again this could be a bash script and none of us would bat an eye.

Any thoughts would be greatly appreciated. Thanks!

EDIT: SOLVED

It looks like it was much simple than I thought and someone solved it on Reddit already. I won't delete, just leave the link if someone is interested.

Runtime Environment

Issue

Sometimes I use "whereis" (aliased for "wh", but it doesn't make any difference...) for my own scripts.

I usually copy their paths manually (using tmux) and paste to the command line resulting in something like this:

nvim /home/my_username/my_scripts_folder/my_script

Could I make that into a single command?

Thanks in advance!

I know there are similar products I could buy in the US that would give me this experience, but I'm not in the US and I don't have much money.

In the old days, my father had some kind of machine that was not a proper laptop and not a proper typewriter. It opened instantly to a text editor. As far as I remember, there was no noticeable boot time. It had a keyboard and an entry for a floppy disk. You typed your stuff, saved it to the floppy disk, probably to send via email or to print in another machine. I loved that machine.

I love these little gadgets that do one thing and one thing only. And, as someone with severe ADHD, they're often a necessity. If my Kindle had Youtube I would never read a book. If my PS4 had Emacs I would never play a game. The list goes on, but the principle is this: a lot of things are useful to me precisely because of what they cannot do.

And that is why I wanna recreate my father's crazy computer-typewriter.

Because I know how to use the command line, it really needs to be in total lockdown: I open it up, it shows a very simple text editor (with a few handy features that make it works even more like a typewriter) that I cannot configure, tinker or alter in any way. It's focused on writing (not editing) literature because that's what I need and other kinds of writing require an internet connection.

It would save and back up automatically (like a typewriter) to one or more drives at your choice.

There would need to be a few options because of different screen sizes, the number of screens etc, with an interface to make it easier.

So the idea is an ultra-minimal, kiosk-mode Linux distribution that can either go on a flash drive or be installed on an old laptop. No package management, no internet connection, no access to the command line, no configuration files, no distractions whatsoever. I wanna forget I'm even using Linux. I wanna recreate my father's typewriter/computer that he never let me touch.

How do I do this?

I've been using Linux for the past 5 to 10 years. I'm not a developer, but a mid-to-advanced user. I don't really know bash (or any programming language for that matter), but I got a folder with 100 bash scripts I wrote myself. I compile my own Emacs (which I configured from scratch and contains more than 200 crudes functions of my own), Neovim (also configured from scratch) and other programs such as suckless terminal. I'm an i3wm user and currently use MX-Linux. I'm very good at Googling and pattern recognition.

I got a brand new AMD desktop with a Ryzen processor (no dedicated graphics, wifi works fine with a USB adapter). Should I try Gentoo, or maybe I should study more (maybe with something like Linux Journey)in order to get a better experience?

Reasons to install Gentoo:

1. Learning experience
2. A completely customized desktop experience
3. Never having to reinstall my operating system again
4. Masochism
5. Putting my powerful processor to work
6. It seems cool (and less painful than LFS)
7. Some hypothetical performance gain

I've got a smaller desk with two monitor arms -- one with a monitor (left side, different system) and one with a VESA mounted tray for my macbook pro (late 2013 15".)

I'm going to be adding a 1440p monitor from the macbook pro, but I'm short on desk space. Instead of having the laptop on the tray normally, if I lay it lid down with the laptop portion up, the laptop base could sit behind the new monitor with the screen coming out the bottom -- perfect for static applications like VSCode, iTerm2, etc.

Here's a mock up. The thicker outline represents the macbook pro screen.

Can anybody foresee any issues with this configuration?

Hey ~, I'm trying to get a programming job. I don't have a degree (I may go to college, but if I do it'll be in a few months), and little work experience. Do you have any tips that could help me have a successful job search?

Here's my resume (somewhat anonymized). I tried to focus on experience I've gained from creating open-source projects to show the skills that I have. I've made sure that all the projects listed have demos, screenshots, usage instructions, etc. Any advice on how I could improve it would be appreciated.

Thanks!

Hello! After spending many development hours in my past years running on Virtualbox/Vagrant-style setups, I've decided to take the plunge into learning Docker, and after getting a few containers working, I'm now looking to figure out how to deploy this to production. I'm not a DevOps or infrastructure guy, my bread and butter is software, and although I've become significantly better at deploying & provisioning Linux VPS's, I'm still not entirely confident in my ability to deploy & manage such systems at scale and in production. But, I am now close to running my own business, so these requirements are suddenly going from "nice to have" to "critical".

As I mentioned, in the past when I've previously developed applications that have been pushed onto the web, I've tended to develop on my local machine, often with no specific configuration environment. If I did use an environment, it'd often be a Vagrant VM instance. From here, I'd push to GitHub, then from my VPS, pull down the changes, run any deployment scripts (recompile, restart nginx, etc), and I'm done.

I guess what I'm after with Docker is something that's more consistent between dev, testing, & prod, and is also more hands off in the deployment process. Yet, what I'm currently developing still does have differing configuration needs between dev and prod. For example, I'd like to use a hosted DB solution such as DigitalOcean Managed Databases in production, yet I'm totally fine using a Docker container for MySQL for local development. Is something like this possible? Does anyone have any recommendations around how to accomplish this, any do's and dont's, or any catches that are worth mentioning?

How about automating deployment from GitHub to production? I've never touched any CI/CD tools in my life, yet I know it's a hugely important part of the process when dealing with software in production, especially software that has clients dependent on it to function. Does anything specifically work well with Docker? Or GitHub? Ideally I want to be avoiding manual processes where I have to ssh in, and pull down the latest changes, half-remembering the commands I need to write to recompile and run the application again.

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've recently started taking some IT and programming classes at a local college because I've always been interested in IT as a career but I've never had any sort of professional experience in the field. Are there any skills that I need to definitely know, or any sort of certifications that I can get in order to get my foot in the door and start applying for IT focused jobs?

Does anyone have any experience working as a contractor in the IT field? I have 4 years of experience in the IT industry, all of it as a full time direct hire. I may have an opportunity to work for a very large company on a 2 year contract at fairly reasonable salary increase. The most important part to me is that I will be getting some experience off of the service desk as well, which I can use to continue my career going forward.

My main concern is that I am unfamiliar with contract work. I do know that I get health benefits / 401k / sick days, but I assume there must be a drawback to being a contractor, right? I feel like being a contractor is inherently more unstable than being an actual hire. The position I am being considered for is a 2 year contract, but I worry that the position could simply disappear a few months in and I'd be out of a job. Is this a fair feeling, and is there any way I can gauge how true this might be for my position? Is there something I could discreetly ask in my interview that might help me understand if this is a stable position?

If anyone has any experience as a contractor, I'd love to hear it.

Hi guys,

I'm really stumped and looking for a nudge in the right direction for how to utilise the ghoneycutt/pam module in puppet. Relatively new to this but got what I'd like to think as most the basics down.

I've configured a few things using modules such as NTP, SSSD and NSSWITCH but I'm just stuck on how I can use this module and pull info from Hiera into it.

So, lets start with

.yaml file:

        ### nsswitch.conf authentication configuration

        nsswitch::passwd:     'files sss'

        nsswitch::shadow:     'files sss'

And then looking at the nsswitch.pp file:

        ### nsswitch.config setup

        class profile::linux::base::nsswitch {

        # Get heira values

          class { 'nsswitch':

            passwd    => [lookup('nsswitch::passwd')],

            shadow    => [lookup('nsswitch::shadow')],

Simple enough to call the values I want and works how I want, now I'm trying to do the same type of thing for PAM using the ghoneycutt/pam module and there doesn't seem to be much info on how to use it, or it's just not sinking in for me.

Some of my PAM Heira values:

        pam::pam_auth_lines:
          - '# Managed by Hiera key pam::pam_auth_lines'
          - 'auth        required      pam_env.so'
          - 'auth        sufficient    pam_fprintd.so'
          - 'auth        sufficient    pam_unix.so nullok try_first_pass'
          - 'auth        requisite     pam_succeed_if.so uid >= 500 quiet'
          - 'auth        sufficient    pam_sss.so use_first_pass'
          - 'auth        required      pam_deny.so'
        pam::pam_account_lines:
          - '# Managed by Hiera key pam::pam_account_lines'
          - 'account     required      pam_unix.so'
          - 'account     sufficient    pam_localuser.so'
          - 'account     sufficient    pam_succeed_if.so uid < 500 quiet'
          - 'account     [default=bad success=ok user_unknown=ignore] pam_sss.so'
          - 'account     required      pam_permit.so'
        pam::pam_password_lines:
          - '# Managed by Hiera key pam::pam_password_lines'
          - 'password    requisite     pam_cracklib.so try_first_pass retry=3 type='
          - 'password    sufficient    pam_unix.so sha512 shadow nullok try_first_pass use_authtok'
          - 'password    sufficient    pam_sss.so use_authtok'
          - 'password    required      pam_deny.so'

Some things I've tried:

1:

        class profile::linux::base::pam {
          # resources
          class { 'pam':
            password-auth-ac  => [
              lookup('pam::pam_auth_lines')],
              lookup('pam::pam_account_lines')],
              lookup('pam::pam_password_lines')],
              lookup('pam::pam_session_lines')],
           }

2:

	
	      passwd  => [
	
	      lookup('pam::pam_auth_lines'),
	
	      lookup('pam::pam_account_lines'),
	
	      lookup('pam::pam_password_lines'),
	
	      lookup('pam::pam_session_lines'),
	
	      ],
	
	  }

        include ::pam

	class profile::linux::base::pam {
	
	  # resources
	
	    include ::pam

	         lookup('pam::pam_auth_lines')
	
	}

I've tried a few other ways and can't get it to work as I want it to. Can anyone help?

Thanks

I don't know what is the correct word in English, but I'll be one of those guys who will teach a "class" consisting on answering questions and guiding them through the exercises.

The content is very basic algorithms in C, so things like functions, pointers, and structs are off the scope. Here is the repo I made with the solutions for last semester. I'm starting in the second semester, so I have everything fresh in my memory.

I welcome anything you can give but I'm not necessarily seeking technical advice since the teachers have that covered. What I'd really like to know is what you consider to be some good examples, attitudes, and approaches for this particular position. Thanks.

I wish I had a dollar for every time I heard a manager complain, “The HR department included ‘must have college degree’ in the job req even though I don’t care” or “They asked for 5 years of experience in a technology that’s only been around for 3” or “I have no idea why they rejected this candidate without even contacting me.”

Still, in many cases you don’t have a choice. If you want to hire someone, you need to deal with HR, at least to a small degree – especially if you work in a big company.

So I’m writing a feature story for technology managers, collecting real-world advice from people who learned their lessons the hard way. Here’s the questions I’d like you to answer:

• Tell me about a frustration you had with the HR department (in regard to hiring). That is, tell me a personal story of HR-gone-wrong. Because we all love schadenfreude, and that gives me an emotional example with which to begin.
• Let’s say you have a new opening in your department. In what ways do you involve HR? (That could be anything from, “give them general guidelines and let them choose the best candidates for me to interview” to “I do the search myself, and use HR only for on-boarding.”) What makes you choose that path? How much choice do you have in the matter?
• What weaknesses have you discovered in your HR department’s ability to serve the needs of a tech-focused department?
• What have you done to cope with those weaknesses? Which of those efforts worked, and which failed?
• What do you wish you knew “n” years ago about dealing with your company’s HR department?
• So that I can give the reader some context: Let me know how to refer to you in the article (at least, “Esther, a software architect at a Midwest insurance company”), and give me some idea of your company size (because the processes appropriate for a 70-person company aren’t the same for one with 7,000 employees).

You don’t have to answer all those questions! I asked these to get the conversation going. Tell me as much or as little as you like.

Please don’t assume that I think HR always sucks. However, there isn’t as much to learn from “why HR is your friend.” The idea here is to help techie managers cope when HR doesn’t offer what you hoped for.

I'm currently researching the cheapest off site backup system and it looks like leaving a hdd at a friends house is the best option. The only thing I am stuck on is how to access it remotely. I need a system on a chip that I can plug in to the hdd and Ethernet and that provides ssh access. My first thought was a raspberry pi with a sata to usb cable but since I will only be doing weekly backups it makes no sense to keep the drive spinning 24/7. I need some way to turn off the drive and then back on over the internet. From what I understand there are linux programs that can do it but only directly over sata because the command doesn't work on usb sata controllers.

What I need is a cheap linux SoC that has sata and ethernet. Does anyone have any ideas?

If you have built from source, then you know the relief when nothing interesting comes out of ./configure && make && make install. In fact, the less interesting the output of these commands, the better.

But occasionally, the source build process is so horrifying that you end up having to modify the configure script or makefile yourself.

So far I have only been able to do this when I was lucky enough to find some poor, destitute stranger who had pretty much the same problem as me ( most recent I can think of is GNUTLS, where I had to adjust the version requirements for nettle ) and that is a problem -- there must be some way to learn this myself.

Is this just something that comes with time and experience, or does anyone have a reliable guide or resource for modifying makefiles and configure scripts? I would appreciate advice / discussion: I am tired of "getting lucky" with these!

I was looking for preferences on 120/140mm case fans. RGB is a want, but not at the expense of quality fans.

I'm pretty new to the topic and not super familiar with the technical side. So open to reading more in depth too.

Thanks!

Mostly the title. I have experience with Python, and I was thinking of learning more about data compression. How should I proceed? And what are some good books I could read, both about specifics and abstracts of data compression, data management, data in general.
