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 bought one of those cheap miniature drones that are flimsy but overall pretty fun to start with. Now, I have the bug to get something with a camera, more flight time, and can withstand the wind. Any suggestions on what I could get <$150 that would be a good investment.

Any maintenance tips or flying in public tips?

For me, that'd be a multiplayer war sandbox. Take a big map, plop down resources, population centers and factories, spawn a lot of players who then have to organize to fight a war.

• To add espionage, you'd not hard-code a lot about the way teams organize(think removing the guild mechanics from WoW), so one could sign up with one side, then run to a different side (who do not know you already signed up with the first) and do ye olde double agent.
• Research could be modelled as being done by NPC civilians, which produces documents detailing the results. These documents must be on-site whenever the research is being used (i.e. present at factories), so it could be stolen.
• No need to go factorio on the production chains. Their purpose is mostly to enforce cooperation to reach better hardware for the guys in the field.

So, what's your crazy dream game that's never going to be built?

Months ago I decided I was going to build my own underwater remotely-operated vehicle. I got sidetracked by a kitchen remodel, but since it is now complete I will have some free time to start working on my vehicle. There are some decent videos out there where others have done the same thing, some are wildly complicated and others are basically built from items out of a scrap bin. I am hoping to land somewhere in the middle.

During the bit of research I have performed, I discovered companies selling very high-end parts, the likes of which you would find on a highly funded/sponsored deep sea expedition or a government project. I didn't find a whole lot of middle ground really, either you DIY or you dump a ton of money into it.

My plan is to use PVC for my hull. I had thought about constructing it similar to the Russian Typhoon-class submarine, with two pressure hulls within an outer hull. That would allow the electrics to reside in dry compartments while I use the void space for ballast. I even found RC submarine ballast systems on eBay which would allow me to take on water and dump it remotely so I could trim it out on the fly.

The general opinion, I have discovered so far, is to make it neutrally buoyant. As much as I would like to add that ballast tank system I may need to just keep it simple for my first attempt. Tethers also seem to be an issue, adding too much weight when they get to a certain length and if you do not take steps to make them buoyant. I thought pool noodles, but learned from someone else that they become water logged and are a bad choice. Then there is power, the trend I noticed is keeping it onboard in the form of a battery pack, but I would like to keep it ashore and just add a wire to the tether so I can not have power to worry about.

So far I have an Arduino board, some old laptops, and some rivers to explore. If we had a makerspace or hackerspace nearby I would be all set. I did search, and the closest is an hour away, which is disappointing since I know I am not the only person into ridiculous projects/hobbies around here! Anyone on here into things like this?

[I'm tagging this as "adult", for purposes of open discussion, with apologies to anyone who may consider the topic inflammatory or sensationalistic.]

Based on discussion of loneliness elsewhere, I'm curious as to what adaptive measures people undertake to promote life satisfaction in the face of environmental/cultural/social stressors.

The word "drug" is used very loosely here, and basically refers to any strategy for purposefully altering neurochemistry - in addition to licit or illicit substance intake, it could be endorphin-boosting exercise, going out with friends, naps, particular reading genres, a good meal, games, direct brain stimulation, meditation, sexual activity, long walks in the country, or whatever.

I'm also taking for granted the proposition that intentionally seeking beneficial neurochemical states is a human activity that everyone participates in, whether they're aware of it or not, and desirable as long as it harms no one.

This is not an attempt to incite, advocate for, or excuse breaking any applicable laws, but a request for information on what people actually do and prefer. If you're concerned about potential legal implications of confessing to an illicit favorite, please discuss in terms of "a friend/someone I know, likes substance/activity x because y".

"Favorite" excludes strategies you've found harmful or destructive, but discussion and/or warning is worthwhile if you feel like it.

I'll start off by saying I have an acquaintance who finds psilocybin micro-dosing very effective at inducing positive emotional balance, mental focus and good sleep regulation.

One of my favorite things over at Reddit is /r/fitness's Gym Story Saturdays and Rant Wednesdays (and also /r/WeightRoom's daily threads). I don't know if we have enough gym goers people on Tildes yet for a weekly thread on your adventures in fitness, but I figured I'd put one up and see what happens.

This week I did week 2 of Pervertor for 5/3/1 and it has Boring But Big sets as supplemental work. The squat day was hell. This is probably because instead of doing typical BBB, five sets of ten at 50% of your train max, Pervertor does this at 65% of your TM. For me, this meant 5x10 squats at 235 lbs after doing the 5/3/1 sets. I just had to sit down after it was done, couldn't immediately move on to my assistance work. My lower back was especially feeling it, but quads were on fire too. Luckily, was ready to go in a few minutes, but I've never had to just sit there and take a break before workouts like that in my near three years of program lifting.

But no one ever starting lifting weights because they wanted it to be easy.

Anyway, I'm sure y'all probably have better stories than "it was hard to things." Let's hear them.

As a lurker on the somethingawful forums one of my favorite features is a button which will show all the posts a single person has made in a thread. It'd be really handy if someone (like the OP) is answering questions about a topic. It's really nice to have on a more traditional forum website, but I'm not sure how useful it'd be here. Regardless, I thought I would suggest it.

Here is an example: Before and After

There is a tendency nowadays for public officials to characterise loneliness as a public health crisis. I agree that it's a pervasive condition. However, the human condition is not fully medicalizable. I believe we can speak about it just as who we are, according to our full experience, in our capacity as first-person narrator, as witness, as who are the closest to their own struggles.

But it can be really hard to be open, and hence vulnerable, to difficult emotions. In times of distress, our own internal communication can get jammed, and it natural that opening up to the external world may feel as if an insurmountable difficulty.

Nevertheless, the great force of nature, evolution, has given us the ability to listen and be listened to. Its greatest strength may be manifest at the time of greatest need.

Which is why I'd like to have this thread. This thread is for you, if you're feeling lonely at the time, or if you want to share your experience with loneliness, or if you would like to give support to our community members, or just to speak up, or just to listen.

Let us tune in to each other's expressions in caring consideration. We don't have to be perfect in self-expression or empathy -- this is not a contest. This is a fireside chat, a place to rest, reflect, and understand, before moving on.

Are you willing to join the conversation?

during the 90s and early 00s we had an overwhelmingly south american supply of tv soaps, their themes most commonly center around money, intrigue, poor vs rich and the evil characters are cartoonishly evil and good characters are the pariahs of pariahs. Today we have Korean​ tv soaps where the theme mostly center on romcom and incredibly lighthearted and often humourous compared to the south american ones. the evil guys are not truly evil, their just the enemy because of the circumstance and the goog characters are not pariahs. my country is the Philippines by the way.
