Here's a list of a things that came out in this past week, up through Friday. Of course, there's no way to be completely comprehensive with this and I avoided including things where information was too lacking, so feel free to mention anything that isn't on here that you think is worth mentioning. Beyond that, if you have any thoughts of any of these albums, it would be great to hear them :)

Notes:
If you spot any mistakes, let us know.
Parental Advisory version of all albums linked (so NSFW).

Ghostemane & Parv0 - Human Err0r | Song.link says Single but is actually EP.
Idris Elba Presents: The YARDIE Mixtape | No song.link. Can't find anywhere. Linked his record label's official soundcloud, since that's where the other Idris Elba Presents are located, so I assume this one will show up there eventually too.

Thank you to @Cleb, @cfabbro, and @Bauke!

I personally usually heavily mod my games, due to finding the process of modding itself fun, along with me preferring to spend a LONG time at one run through.

As an example, I'd give minecraft where I usually play so-called expert packs, which are basically taking a lot of mods and making them depend on each other for progression.

I just moved into a new apartment, and am using a 32" tv in the living room. The TV is already way too small, but I'd rather prioritize spending on the speakers first.

I thought I could live with the TV speakers, but have quickly realized that they have made watching movies impossible. The dialogue is impossible to hear without cranking up the volume. And then if there is anything other than dialogue, it's way too loud.

The walls in the apartment are fairly thin, so I'm pretty sure a subwoofer is out of the question. So I was looking at soundbars but keep seeing conflicting advice. There are articles like this that make them sound fine, yet when you go to place like /r/hometheater, everyone despises them.

So my next step was to look at powered bookshelf speakers. They seemed like a pretty good option, until I went to best buy to listen to them. I'm not sure if they just weren't set up properly or what, but none of them sounded that great. Especially when compared to the tower speakers they had.

So now I'm at a loss. Should I go with a soundbar, bookshelf, or tower speakers? My budget is under $500.

So, I am far from the most experienced, or the most knowledgeable, or the most active amateur radio operator out there, but it is something that has piqued my interest none the less. Before I got into the hobby, I always assumed that the FCC just game amateurs a small bucket of useless spectrum and that was it. Maybe you could fly an RC plane, but surely that is about as cool as it gets.

It turns out I was dead wrong. Amateurs are allocated bands all across the RF spectrum - more or less. Bands from way below the AM broadcast frequency to way above the microwave frequencies used by our cell phones and wireless routers. Also, you are allowed to legally transmit at up to 1.5 kilowatts of power! That's 3,000 times as much power as your average walkie talkie! :) Also, importantly, the license exam only costs $15.

At many of the lower frequencies, the signals bounce off the ionosphere and you can make contact with people all over the world (propagation gods permitting). At the higher frequencies, you lose that "skip propagation," but more bandwidth is available. There are analog voice repeater networks, digital packet networks, mesh networks running on modified commercial WiFi gear, and even a handful of old school packet BBSes. There are some LEO satellites which run voice repeaters which allow you make international contacts, and sometimes even the International Space Station will participate in events. Lots of cool stuff going on. This hobby is kind of a bottomless rabbit hole of possibilities.

I got my technician license about a year ago, and I have been most interested in the data networking end of the hobby. Despite being a pile of hacks, APRS is still very cool, and sometime soon I hope to set up an AREDN node of my own. Every once in a while I'll call into the local repeaters and shoot the breeze.

So there's my story. Are there any other hams out there?

My laptop is showing sings of death, and I know I will need a new one soon. Also, I am planning to get a tablet and ditch my smartphone, and to stop using the laptop for browsing content: I'll do most of that to the phone/tablet, and use the laptop as an authoring tool: writing and coding.

So I am looking for a laptop that is cheap, light, and can keep running for at least 3-5hrs under mild Debian+Emacs load. Ideally around 11"-13".

Does anyone have a business subscriber Internet connection? Is it worth it?

I just spoke with my ISP, and for an extra $40/mo I can get a static IP address with 100mbps that I can host my own website on. I have a virtualization server, and I've been thinking about hosting my own hobby-scale website for a while. I haven't had any luck finding rack hosting space that I'd feel comfortable using so I'm thinking about just going rogue, and operating solo. If I had a static IP address with a pipe that would allow me to host then all I'd need to do is stand up a server, register a domain, and point it at my IP address.

Other than the typical security risks, what do I need to worry about? Would the experience be worth it?

Long story, but I've ended up becoming the admin of a group on Facebook (the previous admin stepped down in a rush, and added me as he left). And the group has an existing group chat associated with it.

Is it possible to "moderate" this group chat? Specifically, as an admin of the group, can I remove unsavoury/unwanted messages from the chat associated with the group? It looks like I can't.

Can even the creator of a group chat do this? If I close the group chat and create a new one, will I (as its creator) be able to remove unsavoury/unwanted messages from that new chat?

I've done some searching via Google, and I'm not finding anything to indicate that this is possible. If someone posts something unsavoury in a group chat, it looks like the only option is to remove the person from the chat - but the unsavoury messages can't be deleted.

Please tell me that's wrong!

I thought it might be fun to make a little game out of asking Fermi problems and trying to work out solutions to others'.

What is a Fermi problem?

A Fermi problem is (to quote wikipedia ):

an estimation problem designed to teach dimensional analysis or approximation, and such a problem is usually a back-of-the-envelope calculation. The estimation technique is named after physicist Enrico Fermi as he was known for his ability to make good approximate calculations with little or no actual data. Fermi problems typically involve making justified guesses about quantities and their variance or lower and upper bounds.

Basically, these are questions that would be very difficult to calculate exactly without looking up the answer. The goal is to arrive at a good estimate by making justified assumptions. As such, looking up facts and statistics should be minimized or outright avoided (e.g., if the question is "What is the mass of the water in Lake Michigan?", you shouldn't look up Lake Michigan's volume to aid your answer. This should be estimated from things you know off the top of your head).

The way this thread works

1. If you have a Fermi problem, post it as a top level comment.
2. If you have a solution to an already posted Fermi problem, post it as a reply to that comment. Be sure to post your reasoning and thought process.

Fermi problems can be fun to come up with, and fun to answer. Examples of Fermi problems might include:

• How many piano tuners are there in Chicago? (this one is apparently one that Fermi came up with himself)

• How many keystrokes occur worldwide, daily?

• What is the mass of the water in Lake Michigan?

• How many cars are there in New York City on a given day?

• How many blades of grass are there on the National Mall?

• How many eggs are consumed in the US each day?

Since many of these have no definitive answer, it is not always possible to score the 'correctness' of an answer. Nonetheless, others can judge when an answer makes reasonable assumptions, so feel free reply to answers with suggestions of which assumptions can be refined or further justified.
