$12 is cheap for something that lasts years (with occasional use) and prevents you from going deaf at rock concerts, while still allowing you to hear the music like it was supposed to sound, instead of sounding like you are underwater. These are not audiophile pseudoscience garbage, the frequency response of the earplugs is scientifically quantifiable, and the difference in sound quality is immediately obvious to anyone who tries them, not just idiots with "golden ears" who can hear differences that don't exist. Like the AC posted, these aren't the only brand, but AFAIK they all are pretty much in the same price range until you get into custom fit professional models, at which point you are paying for comfort more than quality.

Yeah, and good earplugs like these have a nearly flat frequency response which make it easier to have a conversation in loud room, unlike foam earplugs or headphones that muffle the sound in addition to attenuating it.

Well it was a little more than that. For some months automounting of USB drives was broken for any combination of X11 display manager and window manager except GDM and gnome 3 because the systemd udev apparently handles that stuff differently than the old udev.

And this is why people get upset about systemd. I actually like the idea of systemd as a boot manager. Elimination of pointless boiler-plate demon scripts, better exposure of all sorts of cool kernel process management features, and using filehandles activity to manage the order in which daemons are launched (rather than explicit declaration of daemon dependencies), dovetails very nicely with the unix philosophy that everything is a file.

But it has becoming a sprawling feature creep monster, and I don't like that. I don't like that the developers put on false airs about how they aren't forcing you to use the other 68 daemons under the systemd umbrella, while making design decisions that make it next to impossible for distros to deploy anything but an all-or-nothing solution. I don't like how they are unilaterally making compatibility breaking system level decisions that affect everyone without giving adequate consideration to the rest of the ecosystem. That sort of attitude and approach is only going to cause more problems in the future, not less, which makes me very wary of getting on the systemd train, even though I like the technical core.

Like you said, this is a beta distrubution so as a user I'm not upset that it was broken for a while. I'm upset at the undue upheaval that one project is having on the entire Linux ecosystem.

From the article most of the spending is on things that are beneficial to society as a whole, not just NSA. These include K-12 funding for science fairs, math clubs, and STEM summer camps. Unless the NSA is influencing these in harmful ways, such as pushing ideology beyond the normal "if you do well in school, you could do cool spy work for us" recruiting I don't see a problem with taking their money. Same for the research grants and conferences, which all result in publicly published fundamental research, that help the entire cryptographic and big data communities as a whole. The only program I would have a problem with are any classified research and the sabbaticals to do classified work at the NSA.

No, you could use a conductive rail, like a subway, and rack and pinion system to move the elevator. The rack and rail would add a fair bit more total weight to the building compared to a cable. But more importantly, the motors would have to be much much more powerful! Modern elevator systems have a counter-weight balanced on the other side of that cable, which means the motor only has to overcome friction and the small difference in weight between the elevator and counterweight (which varies depending on current payload). The motor on an elevator like Noah is suggesting would have to provide enough force to counteract the entire weight of the elevator + payload + motor + friction, which is at least an order of magnitude more than a traditional elevator.

No, good scientists understand significant digits. As far as geological epoch go, the time elapsed between the start of the industrial revolution and the start of the nuclear age is insignificant. Furthermore, while the technology began at the industrial revolution, the impact of that technology didn't have global environmental scale until later on. We don't mark the other geological boundaries at the point where precursors to change appeared, we mark them when change became significant. If you look at graphs of human energy or CO2 output, the knee in the curve does occur at around the mid 1900s. The fact that there happens to be an easily observable geological marker that occurred at that time makes it a convenient dividing point, and as good as any other of the arbitrary dates picked to divide otherwise well-distinguishable geological epochs.

If anything, I would argue they risk jumping the gun too early, not setting the date too late, as there may very well be a much bigger global change in the next 10's thousands of years of which the last millennium will just be regarded as a precursor to.

Tax preparation software is not a good candidate for open source software. You need domain experts (accountants and lawyers) to be involved to validate the interpretation of the Tax Code; open source projects have a difficult time attracting these sort of contributors. The law changes every year and if you don't keep on top of the changes becomes worse than useless; it becomes a liability. You have solid deadlines; you can't just release when it is ready.

One important point that others above have alluded to but haven't outright stated:

While the exponential scaling of rocket equation is an important limiting issue when building larger and larger rockets, for any given rocket (or rocket configuration) the payload capacity is fixed. If you have a payload that is too large for a Falcon 1Pegasus, but doesn't need the full capacity of a Falcon 9, all that extra capacity goes to waste. It costs essentially the same amount to launch a Falcon 9 at 60% capacity as it does to launch it at 90% capacity. You can share payload with multiple customers, but that limits which orbits they can use.

Space X can calculate how much weight the recovery system and fuel requires and how much money they can save by reusing the first stage, and give a discount to customers who give up that additional payload capacity. If there is a market for those lower cost launches, then great. If not, then keep treating the 1st stage as disposable.

Running a business like this takes a lot of work, and for it to succeed well enough to actually get working rockets off the ground you need to attract top-notch engineers who believe that working for you isn't just a waste of their time (more than a billionaire's plaything), and management that can create the right environment for them to succeed without blowing through your money for nothing. It is much less expensive, less risky and less time consuming to just pay Russia for a thrill ride than to create your own rocket company. So I can understand why most would choose to go that route, and leave the latter for those who genuinely want to shake up the market.

That said, the total payload mass that the ship could support is roughly the same whether it is inside the airship or outside in a gondola, and the more space you want to make available for use, the more mass you would have to dedicate to structure rather than payload. So it would be less cramped than a tiny capsule, but you would still need large expanses of mostly empty space to provide the needed buoyancy.

In practice, it might be better to have a balloon filled with a less dense gas to decrease the total volume needed to support the desired payload, and then have an attached air-filled "gondola" that is nearly as large as the balloon.

Like Disney World, will it also have accompanying lodging.

You don't have to wait for someone to pop out of the woodworks. BPG is nothing but a still frame of HEVC video which is patented up the ass. Bellard and other open source video authors are accustomed to ignoring the patent situation because they don't really have a choice if you want to be interoperable, but that isn't an excuse for creating patent problems in a field where there are already widespread royalty free standards (JPEG, PNG).

Yeah same here. The only bad thing I saw were the MRAPs which have already been in the local news. I can't imagine that there are enough situations where such a vehicle would be needed to justify the high maintenance costs. They are mostly used for show, as projections of power.

Other than that, it's a bunch of useful items. The larger police departments got explosive ordinance disposal robots, scopes, utility trucks, helicopter. The forest service got a bunch of night vision supplies. The department of corrections got a big ol power distributor. One of the more rural tribal departments got a road grader, some generators, welders, and even a field kitchen.

Good to see that tax payer funded equipment going to good use.
