The kind of incident that happened on this flight is incredibly rare, and in fact nobody got hurt. Sadly, while I get where you’re going, what you propose would almost certainly make emergencies more common, not less.

To implement your solution you’d need at least:

- Some kind of mechanical release to let the engine go

- reliable ways to disconnect the electricity, fuel, control, hydraulic and other connections without affecting the rest of the aircraft when the engine detached

- a parachute with a release mechanism

Each of these mechanisms comes with its own disastrous failure case:

- engine mechanically releases when it shouldn’t, taking everything with it (this has happened [0]), or engine is released while still producing thrust despite the fire, destroying the wing or tail

- hydraulic or other lines don’t release when they should, taking everything with it in an otherwise survivable situation

- parachute fails, dropping engine on people, parachute catches fire in flight, parachute accidentally deploys in flight...

This is just off the top of my head, I’m sure there are many other potential problems.

Sometimes the best solution is to work out what happened and make it less likely to happen, rather than add stuff to catch it after it fails.

SLS is such a strange beast. So many weird things about it. Its design looks like someone tried to literally combine a Saturn V and the Space Shuttle: in an alternate universe, it might be the design we got in the 70s instead of the Shuttle. They're using rockets that were used on previous shuttle launches for the first few planned missions -- and instead of reusing then, they're dumping them.

It just doesn't feel like....an advancement. It's not something that can get the general public excited about space.

Edit: it turns out today is the 40th anniversary of the first firing of those rockets while attached to the orbiter (the 'SSME' - space shuttle main engines). https://www.nasa.gov/feature/40-years-ago-two-months-away-fr...
It's been in development longer, and will not carry tourists to space before SpaceX has tourists in orbit.

ULA is a 50-50 joint venture of Boeing and Lockheed Martin, yes.

So if Blue Origin wants to buy ULA, it has to negotiate with both Boeing and Lockheed Martin to be able to do it.

I have no idea if Boeing and Lockheed Martin would be interested in selling. Both Boeing and Lockheed Martin have their own space businesses separate from ULA, and likely view part-owning ULA as having some synergies with their own space businesses, and selling ULA to Bezos could threaten those synergies. OTOH, as they say, everyone has their price, and Bezos has enough money to pay just about anybody's.

A fun Wikipedia page about another time results were published on coherent nuclear excitations is "Hafnium Controversy"[0]. In that case, it was thought that hafnium nuclei could put into a stable state that, through stimulated emission, could be rapidly transitioned to a lower energy state and made to produce an xray photon. This behavior would let you build a really high-power xray laser or bomb.

It seems like the hafnium finding was made in error, but the experiment in this post seems much less showy and more real. Could be really cool for clocks - right now optical atomic clocks are much better than the old RF atomic clocks, with the trend being toward ultraviolet atomic clocks. Xray clocks would be orders of magnitude better than even UV clocks!

EVs still heavily depend on non-recyclable batteries. A much better option would be to get biodiesel to a practical state. So whatever carbon your car releases will get trapped back into another portion of fuel.
I'm not sure if you're referring to https://www.youtube.com/watch?v=gSrnXgAmK8k ("All of our data is gone"), but in any case, I've heard references to ZFS in later videos so yeah, the situation's probably not quite that insane now.

That video is technically hilarious though, it TL;DRs as "download Ubuntu-based USB image provided random RAID recovery company, boot USB and provide said company headless SSH to broken system"... at one point in the video I remember Linus talks to another recovery company about the process and the guy pretty much went "...O.o..." which IMO sums my own opinion up, lol

Yes, the best reason why short sellers short a stock is because they find something fundamentally incorrect about the mainstream perception of a company.

But, what happens when shorting is the mainstream perception? That is when they get squeezed. Except.. unfortunately, there's no other sheriff in town.
The thing I'm imagining is that if there was something I wanted the USE flags for, I'd just end up compiling myself in a prefix. I already do this for some packages because of the issue with Gentoo removing things they consider stale which is the problem.

I don't need USE flags all the time or compiling everything with -O3 -march or whatever, for most things it's just a plus that it might be faster. I think the one thing that might actually matter for me is in Gentoo fixing broken things is more direct, just compile, while I've had issues that persist on ubuntu even after reinstalling something. It just felt like there was somehow "stale state" in my OS which even sounds ridiculous saying. But, at this point, I can't handle breaks in portage because while you can fix things, it requires mental effort on my part and I'm tired of it.

EDIT: reading your comment, if you're asking for my opinion I mean look at this in particular:

https://bugs.gentoo.org/420783

ioquake3 was literally removed from portage for this "bug" which even if you accept that it's a hypothetical issue has easy patches that were never included, and it was removed, essentially removing hosts of open source fpses from portage! I even read a forum post talking about "upstream" not caring...upstream? ioquake3's release was charity, it's not like an active project.

This has been happening for a while. I've been here since 2008 or so and the instability and removal of slots within months has gotten out of hand. Again, the tooling is great, emerge, eix, the whole system of configuration files is awesome and I'm just used to openrc. I wish I could keep them but the slot removals in portage has just become such a chore to deal with.

Is just plainly inaccurate. The phone has nowhere near supplanted the desktop in multiple scenarios. Office work and programming [0] both come to mind.

I don't know much about New Glen or what Blue Origin is doing. Do they have a working rocket (New Glen) or is it still under design? I know Blue Origin was launching a rocket called New Shepard at one point, did they ever get anywhere with that? I was under the impression Blue Origin was more like a Virgin Galactic type of company.
Gateway makes heaps of sense in a reusable spacecraft future. You have vehicles specialised for certain tasks such as ferrying crew from Earth to Lunar orbit and back, and specialised vehicles for landing crew and cargo on the surface.

Starship is trying to be launch vehicle, cruise stage, landing/ascent vehicle and reentry vehicle all in one and has to make huge sacrifices in terms of payload capacity and delta-v to achieve that.

Starship can land on the Moon and return, but it needs a fleet of tankers to refuel it for each trip. A specialised crew transfer vessel (no heat shield, no aero surfaces, no landing legs) would be able to head directly from LEO to LLO and transfer crew without having to be refuelled in a highly elliptical orbit around Earth first. Using Starship to get from Earth to the Moon is like using a Ram 3500 to pick up groceries from the corner store.

Prominent examples would be optical illusions and the kind of thing you find on https://reddit.com/r/confusing_perspective/. Both of which tend to fool for longer than a split-second.

It's not entirely the same method as these "adversarial noise" inputs, but some optical illusions are pretty close in how they mess with the localized parts of our optical processing (e.g. https://upload.wikimedia.org/wikipedia/commons/d/d2/Caf%C3%A...).

We can't backprop the human vision system to find "nearby" misclassifications as easily, and presumably our own "classifiers" are more robust to such pixel-scale perturbations, but especially lower-resolution images can trip us up quite easily too (see e.g. https://reddit.com/r/misleadingthumbnails/).

Presumably you hope the US has a long and prosperous future beyond our generation, so it's a problem that will need to be solved at some point.

I'd say more generally, it's about control and having something police / government can hold over almost anyone, or any demographic, if convenient for whatever reason. That is the danger of these kinds of laws, they are a shortcut around other rules that are supposed to keep police power in check. And as pointed out elsewhere, local decriminalization doesn't really change this. It's a step in the right direction, but what it really needed is an explicit relinquishing of the power over people that these laws afford (in the US, perhaps an amendment even?) Until that happens, drug laws will still serve their purpose

Radar Controllers and Radar Associates are just staffing positions.

Some background information to build on…

An Air Traffic Controller's job title when they start out is Air Traffic Control Specialist. An Air Traffic Control Specialist starts out in the AG pay band (Academy Graduate). When that Controller gets certifications, they move up to the D1 pay band (Developmental), then to D2, D3, and when they get all of their certifications or "fully certify", they end in the CPC pay band and their job title changes to Certified Professional Controller.

The Radar Controller position is also called the R-side, and the Radar Associate position is also called the D-side. A trainee needs to certify on all of their D-sides before they start training on their R-sides.

So basically the answer to your first two questions is "yes". However there can be a more experienced controller working the D-side while a new controller is working the R-side. The Air Traffic Controllers rotate through the different positions throughout the day. It is based on when someone arrives for their shift, or comes back to the control room from their break, they check with the controller that has been on a position the longest, and asks that person if they want a break. If not, the Controller moves on to the next person who has been working the longest, and so forth.

ARTCCs or Air Route Traffic Control Centers or just "Centers", are divided into "specialties" (or "areas") that controllers are assigned to. Each specialty is divided into sectors. At the minimum, each sector needs to staffed by a Radar Controller. If the sector is busy with a lot of traffic or is complex due to weather events, or maybe traffic being rerouted from another sector, then a Radar Associate position will be staffed at that sector. If traffic is very light, for example in the middle of the night, sectors can be combined and one Radar Controller will work multiple sectors and talk to multiple aircraft on different frequencies.

The time it takes to get certified depends on many factors. It could be anywhere from one month, to six months. From starting out to get fully certified, can take anywhere between two years, to five years. It depends on many factors, such as personal ability, training opportunities, training backlogs, etc.

It is common for people to switch facilities at least once. Some stay at their first facility, some move several times. When a Controller graduates from the FAA's training facility (that's where "Academy Graduate" comes from), they are given a short list of facilities to chose from. The list constantly changes based on the FAA's staffing needs.

The FAA does do "direct hires" for people with previous ATC experience (usually through military) directly into certain facilities, but a new hire without experience won't know where they'll go when they start out.

The views expressed here are my own and not necessarily those of FAA.
I’m talking about DeFi - distributed exchanges, yield generating savings accounts, and collateralized loans. Additionally ERC20 stables so on and off ramps are significantly less important. I see Coinbase’s primary function as an exchange and a way to convert to dollars. Both are threatened now. They have low fees, low latency, and more usability... but will that last?

Well-written article and kudos to the author on their career success!

One nitpick, the part about comparing possible startup comp in a unicorn exit and as a senior eng at Facebook over an 8 year period is missing the possible tax benefits of the startup comp. Facebook comp will be taxed as ordinary income as the stock is granted as RSUs (basically 40 - 50% in the US in the $500k/year bracket depending on the state you live in), whereas the majority of a $10 million windfall from being an early employee at a startup that exits after 8 years would likely result in at least half of the tax burden if you did it right and the options were ISOs. With a 4 year standard vesting schedule, the majority of options would have vested far before the startup was a unicorn, and the tax burden at time of option exercise may be very low. Assuming then a long term capital gains rate of 15% at time of sale, the comparison to Facebook comp over the same timeline is about 4x in favor of the startup rather than the 2x the article proposed.

As the author says, though, the startup route is exceedingly risky and very highly likely not to come out ahead.
> I still need Windows on my computer for my workflows though so if the virtualization isn’t even beta quality I’ll need to be an Intel holdout for a while longer.

I’m running the beta of Parallels on M1. Windows works fine, though Parallels itself is still a work in progress. The issue is only licensing with MS, who currently don’t license Win for ARM independently. Then it’s just a question of whether you’re willing to enter a licensing grey area, similar to when you want to pay for content but it isn’t available in a legal format (thus, a person turns to a torrent). This is not an endorsement, just an observation.

Neat, memory mapping is a nifty concept. Are you loading a raw binary blob and directly jumping into it then? That's hardcore.

I'm not familiar with the inner workings of dlopen, but I wouldn't be surprised if dlopen itself is mostly userspace code that knows how to interpret the ELF format, and internally it uses mmap as the actual system call. Maybe it has its own system call, though, to let the kernel do most of the work?

I've seen some really cool uses of mmap. It's nice for reducing the number of memory copies when you're churning through a bunch of data on disk, and often necessary when using shared memory for low overhead inter-process communication. I worked on a project that needed publish-subscribe message passing semantics with fine-grained synchronization across dozens of processes, for example, and a lock-free shared memory "disrupter" queue structure was able to handle millions of messages per second, while sockets could only handle a few hundred thousand or so.

I've seen some unfortunate uses as well. Sometimes folk like the idea of manipulating files on disk as arrays in memory, and use mmap even though there's no practical performance need for it. The code often times ends up harder to read than it would have had it used file descriptors. Also, the performance ends up worse because the implemented algorithm's access patterns unknowingly cause lots of page faults and disk seeks because the data is an "array". Often times there's an alternative way to do the same work sequentially with an additional in-memory data structure, and using file descriptors naturally biases one towards doing that.
LAX doesn’t have an airport station (well, there is an Aviation/LAX station on the green line, but it requires a 10 minute bus connection to the terminal).

SJC (San Jose is the biggest city in the Bay Area) has no airport station for either VTA (light rail) or CalTrain (heavy rail). Both pass within a quarter mile of the airport.

SAN has two light rail stations nearby, but not really at the airport.
