<p>to lose less money on the prisoners?<p>i.e. its not a good motivation to increase the number of prisoners (even if one looses less money per prisoner, more prisoners will mean more loss), but it does motivate investigating ways on how one can minimize the loss on individual prisoners.</p>

<p>I used to walk from the main library to the metreon every sunday (made a day of visiting library and seeing a movie).  It's not a long walk to most americans.  It's easy, in that its a flat walk.  Less easy (at least then) as it wasn't always the most pleasant area to walk through depending which way one went (detours et al).  Staying on market was fine, walking up minna (sp?) less so.</p>

<p>before I learned of shamir secret sharing, I wondered why one couldn't do the same exact thing with a par2 like system (albiet with smaller pieces than a par2 system would traditionally have).  i.e. you have X bits of data, you create Y*X/N sized recovery blocks (where Y > N).  You hand each recovery block to individual users.  and any N users can get together to recover the key and decrypt the contents.</p>

<p>it is annoying that it can't remember it by series.  Perhaps for a normal series I don't want captions but for a foreign language one I do.  Perhaps for a foreign language that I'm good at I don't want it, but for others I do.  Perhaps for a foreign language that I'm learning, I want it in that foreign language (ala english for english content) but dont want it for others.<p>Global "works", but remembering by series would be so much better.</p>

<p>as someone who bought a lifetime pass years ago when it was cheap, I'm more concerned about this indicating that they are in desparate straits and are heading towards going out of business.<p>I like plex, I've tried jellyfin and emby and plex has always come out ahead (handling the metadata and the general user experience) and if plex goes bellyup i guess I'll move, but I'll be sad.  At least I feel I've gotten my value out of my lifetime plex pass.</p>

<p>I had a jellyfin server on the same machine as my plex.  I really tried to use both, the jellyfin experience was so much worse overall.<p>It had one technical feature that I valued (the ability to tone/color map dolby vision content for non dolby vision devices), but that was such a minimal feature for me (very little of my content is in the proprietary dolby vision colorspace).</p>

<p>why could you not implement it as ptys.<p>Currently the terminal doesn't really process input itself, it just gives the program running the "raw" fd.<p>If instead the terminal gave the processes a pipe (for instance) and consumed all the pty input itself (and its end of the pipe being a buffer of that content), why wouldn't it be the same?</p>

<p>in the country I'm now in somewhere around 18% of my salary is basically put into my "pension" (basically equivalent to a 401k).  around 6% from my salary, around 6% match from employer and around 6% for severance (that one gets when they leave said employer, but can stay in pension, and most reccomend it stay there unless you really need it to make ends meet as otherwise pulling out 1/3 of your pension contributions).<p>This is external to disability insurance that we and our employers also have to contribute to.  So I'd agree to a large extent that the govt forcing employees and employers to contribute significant amounts to 401k like programs could be in the interest of everyone in the USA but one needs a disability insurance program on the side as well and that isn't particularly cheap.</p>

<p>it doesn't cover you getting disabled so you can't work anymore at the age of 30 after working 8 years.<p>1600% higher return is great when you work from yours 20s to your 50s/60s and can essentially self insure yourself at that point with it, but as the person you are responding to you is (I believe) trying to say, that's not everyone.</p>

<p>these policies hurt employees (at least US taxed ones, other countries only tax at liquidity events).<p>Large insiders (founders, investors et al), still get to unload their shares (i.e. to future investors), while employees who might have worked for the company for years and accumulated options (or sometimes unsellable RSUs) due to the company not being public get hit with large tax hits either at the same of vesting (for RSUs, but at least that's somewhat manageable) or at the time of leaving the company (due to the need to buy one's shares within 90 days or lose them and then be hit with a tax on the delta).</p>

<p>why do you assume we wouldn't have seen value in satellites if we didn't see value in going to the moon (or mars)?<p>There's clearly an extraordinary value in satellites from a military perspective, for instance to enable spying.  Heck, Hubble directly benefited from the work that went into spy satellites and NASA was afterwards gifted 2 uneeded spy satellites to use for scientific exploration (1 is (was? as in finished) being converted to be used, the other AFAIK is still in storage).<p>GPS wasn't created to enable us to do anything in space, but to focus down here on earth.  i.e. what was needed to fight wars better.  One can argue if that was "necessary" but it was clearly earth focused.</p>

<p>If one is going to store the originals anyways (i.e. the ISO images one backs up from disc), then I'd still stand by my statement, you're not saving anything by encoding it then, beyond perhaps limitations in how much storage one can keep online at a time (and in that context then, my initial statement of storage being cheap further applies, as one is saving the same content twice).<p>If one is just download encodes off of usenet so doesn't have the originals, and one is content with the limitations of encodes, great.  But here we are talking about tools for people who are encoding their own media (and sadly, from personal experience, I consider backed up ISOs to have a longer shelf life than many of optical discs, I have media I backed up 20 years ago now that still works, while the optical discs have degraded.  Hard Disks die as well, but there are effective means of mitigating that).</p>

<p>I disagree.  But to each their own, also depends how one watches it.  a truehd atmos audio stream for a movie can be 3-4GB by itself.  Of course, for many perhaps a TrueHD atmos audio stream is overkill, but for many its not.</p>
