Looks like the market for third-party heatsinks is about to explode. Almost all of the megacorps will have all-in-one (or as close to all-in-one) headsets out by the end of the year.

https://www.vive.com/us/product/standalone/

In their Creators Update released last month, Microsoft gave everyone a demo of their "Mixed Reality" portal, the shell for what they're calling 'Windows Holographic." soykaf looks like fallingwater; they have even more OEM partners releasing their own headsets as soon as August.

Vive is trudging along, and we probably won't hear much from Oculus until Connect in September. But have any of you lainons been getting into VR? What are your thoughts on it, preliminary and otherwise?

I have a vps with digital ocean and a home desktop and a work desktop.

I want to ssh from my work desktop to my home desktop, but my home desktop is behind a NAT and inaccessible. Is there a way to use the vps I have as a gateway/jump box?

What is the best way to do it, and is there a term for it? (I think I have heard people call this setup a 'bastion host')

Reverse SSH tunneling. A VPN if you want something more robust.

keybase is taking off apparently, it now has a iOS and Android app and yet things like pass and mutt don't integrate well with it, feels bad man.

I'm not really sure what their purpose is. Sure, a key server is useful, but uploading your private key to the cloud?

As an Android app I use OpenKeychain, which even has the ability to get keys off of keybase iirc

 No.247

>>246
Well I'm uploading it in a way or another to the so called cloud because I need to back up.( I simetrically encrypt it of course but in the end it's still in the cloud)"

 No.248

>>247
if you encrypt it yourself it's quite safe, but that's not the case when you give it to keybase

 No.249

I find it useful for downloading nodefiles videos. And that's all keybase has for me now.

Inevitable in the sense that any civilization with technology approximating our own—before computers—would discover computation. This question is independent of whether their computers would be instantiated anything like those that we have designed or built. Another way to think about the question is to consider how our own history might have unfolded such that the invention of computers was accelerated or delayed. How early or late could have it been otherwise?

I am inclined to think yes, a method for automating computation, that is the calculation of some result.
Actually, while what you mean right now is digital computers, there have been analog computers for a long while now. Pic related is an example of an analog computer. But there are much older computers, such as the astrolabe, which has been around since the middle ages.

i took it to mean computation in the "as opposed to conversion" state, so a slide rule wouldn't count.

that is to say, "a computation device takes some form of input, maintains some internal state which is affected by the input, and produces some output which is affected by the state".

the jacquard loom, which everybody loves to mention because Punch Cards, also wouldn't count, as it produces it's output directly from the input: conversion.

i guess the ole' difference engine does count then, though; hadn't thought about that.

 No.155

>>141
From information theory perspective conversion is computation. All CPU does is iterate "conversion" of the machine state, which is both input and output. Information theoretically computations differ only (?) by the number of bits they erase (those that erase some require energy to perform, those that don't - don't) and time they need to propagate signal from inputs to outputs.

i see it intuitively as a difference in input granularity. that is to say, any deterministic device will give exactly one lifetime-sum output for exactly one lifetime-sum input. that is to say, if you consider every bit of input a computer ever receives during its lifetime of operation as a single input (ignoring the effects of unintended inputs, like electronic interference or whatever), you could build an equivalent "conversion device" that produces the exact same output for the same input.

the difference comes when that input is broken down into smaller pieces. every continuous, start-aligned subset of this summed input could be considered in the same way, and thus emulated in the same way with a conversion device, but the complexity of a conversion device designed to perform all of these conversions would become the sum of the complexity of all those different subsets of the input (or you could optimise it down using currying, and maybe some other fancy things, sure, but that's not fundamentally different for what i'm getting at).

the point is that, as this summed input approaches infinite length over the lifetime of the machine, the complexity of an emulating conversion device would also necessarily approach infinity, while the complexity of the computation device never changes.

you can make a LUT which matches a function with infinite range, but only over some finite selection out of that range.

so yeh, that feels like an inherent difference to me.

Conisdering a computer is simply a device for computation and calculating numbers, yes I believe it would have been inevitable, as it is human nature to find ways to improve efficiency in whatever they wish to do, as to not have to do it. Out of laziness. Such as an Abacus.

You can also consider another person a "computer". In the past people used to take up jobs simply for the easy calculations, for things like ship's, etc. This can be seen through the 1640's definition of Calculator, "one who calculates".

There's this web serial that is completed named Worm which a few of my online friends have recommended to me. It's finished and located here: https://parahumans.wordpress.com/table-of-contents/

How can I set up a rss feed where a chapter a day is pushed ?

* I'm doing this because I always read up what shows up in my rss feeds, this way I condition myself to actually finish this eventually.

 No.17

I've been thinking about something similar before. The problem is that you can't go back in time and get the necessary entities from the original feed, so getting the actual content into the feed could be a bit tricky.

However, if you are satisfied with something simple that you give a list of links and it gives you a feed that pushes a new link from your list every day, that should be pretty easy. I don't know of any software that does this but it shouldn't take more than a weekend to create one.

 No.18

You could just crawl the site with a python/ruby/whatever script and make a daemon post updates to some rss feed every day.

There's modules/libraries ready-made for that.

 No.159

the rss file format is super simple xml:

https://en.wikipedia.org/wiki/RSS#Example

so you could:

1: run a quick scrape for links on that page and stick them in a plaintext file.
2: write a script which removes one link from the head or tail of that file (depending on the ordering you used) and inserts a block for it into an rss file.
3: make a cron job to auto-run that script once a week.

…and you're done!

 No.163

I see no problem with that except for the fact that the rss feed won't contain all the entries.

your welcome, it's been my favorite for a long time.

just keep in mind it has a client ui seperate from the backend, so it's great for throwing onto a headless box and controlling via SSH from anywhere without sticking it into a screen/tmux session :)

you can also in the same manner pass commandline options to it to control from elsewhere. I used to keep a server (old celleron 800) in my wardrobe and I had a cron job to play music as my alarm every weekday morning at X oclock. Kept an old laptop with a dead battery hooked up via a serial RS232 console connection for actually controlling the 'stereo' system.

 No.156

>>96
Have you looked at ncmcpp? One of the advantages to using mpd (the daemon backend behind ncmcpp), is that music keeps playing after you kill the terminal.

So you don't need the terminal window open.

 No.162

>>156
you don't with mocp either. it's not as obvious with mocp in comparison to mpd but mocp does spawn it's own daemon on start that you can then either control with the console ui or pass commands to manually.

and yeah, back many many many years ago I did look at mpd but for the complexity in setting it up it didn't really seem to offer many bonuses on top of what I can do with mocp in one command.

it always looked cool but for my purposes it was always overkill.

Hello, I've been trying to root a ZTE Maven running android 5.1. I used cydia impactor, but whenever I hit start it always freezes at pushing SU temporary. Additionally, everywhere I read about it, it says to have #drop super SU su to /system/xbin/su, which is not available for me.( It says install SuperSU (aka, root my Android) Is there something I'm doing wrong, or would i be better off using a different method?

Hello everyone,

I came across this thing called a nomx.
As to what it is, you may ask "Nomx provides a device that you keep in your home or office for all your communication needs."

Video;
https://www.youtube.com/watch?v=9VFnlVzjE68&feature=youtu.be

A guy named Scott Helme seems to have been doing some punches at it. Which you can read more of here.
https://arstechnica.com/information-technology/2017/04/punching-holes-in-nomx-the-worlds-most-secure-communications-protocol/

Examples of the issues.

The code is riddled with bad examples of how to do things, and it seems was developed by one guy called 'shawn' whose name appears throughout. They narrowly avoided one persistent XSS vulnerability by stripping tags; this was followed by the comment / should we even bother? /.
