Range for the J20 and the F22 is available from Wikipedia.

From Wikipeia again the F119 engine of the F22 can deliver a maximum of 35 000lb of thrust.

Thrust figures for the WS-10C are harder to come by however. I had found a source giving a figure of 167kN but I don't believe this source is accurate upon further review. We can thus settle on a current figure of 35 000lb = 155kN for the older WS-10G, with the J20 now being only equal to the F22 for lack of a better source on the most recent engines. The source for this figure is Deagel.

Much more powerful engines for the J20 are under development (180kN = 40 500lbf) but they are not reliable enough for fielding yet.

So as of yet the J20 is most powerful ex aequo with the F22 but has a longer range.

To note however, thrust is probably not a very important factor in the era of beyond visual range fights.

Do you--or anyone?--know of a good place to know the status of "what actually is the bounds of safe"? Like, "if you use Linux X.Y with this compiler setting and option set then separate processes are safe" or "if you use Xen X.Y and are a Linux guest--maybe also at some X.Y/whatever--that is safe"... or are we simply at "if you share any CPU hardware at all, you are never safe and should give up hope"?
I’m not sure whether situations in CJK matters here, Mongolian seems cursive only to me. Cursive was not included in typed CJK texts and what remains is block forms which can be arranged in any orientation(though vertical top down and horizontal left to right are strongly preferred), so CJK are probably easier than Mongolian.

The overcrowding you describe is endemic in California. Likely, nearly all you food is produced by people living in overcrowded housing, worse than you describe. What you describe is common for the people who serve you food in restaurants, and restock the shelves, and do pretty much all the stuff that makes society run these days in California.

And we got to that point without concrete boxes at all. Avoiding density isn't helping.

Let's imagine density, but with enough living space so that each person gets their own room. Let's imagine that we build so that we don't have to hear our neighbors' partying. Let's imagine that a full time wage lets somebody rent their own 1 bedroom apartment.

The only thing stopping us is an electorate that has your beliefs. We don't get crowding from building more housing, the idea is preposterous on its face. It doesn't pass a basic sniff test. We get overcrowding because we didn't build enough.

The latest Starship SN15 launch (and landing!!) apparently had a Starlink antenna mounted on the side so it might not be that static in the future. At the same time the video feed was pretty choppy so if it was due to going via Starlink they still migh have to work on in a bit. :)
True. I have a blind spot around the schools situation since I don't have kids of my own. I tend to forget the full extent of it as it didn't impact me or my immediate friends much (school closures) as I have few friends with school aged kids anymore (they're all infant to toddler or college aged or older).

Restaurants, bars, and schools were the things most consistently closed. Around here, they opened up for this current (now finishing) school year but had frequent closures based on COVID cases amongst the students/staff with an option to stay home the whole time if desired.

> Strike 2/2 was multiple devs responding to OSX issues with "switch operating systems"

What are the devs supposed to do? Debug the proprietary driver? They might not even own a Mac device because they give the software away for free and don't want to spend thousands on their spare time hobby. OpenGL drivers, regardless of manufactuer btw, have massive issues with bugs. They were so serious in fact, that the original glium maintainer gave up maintaining it. Having taken over emergency maintainership of glium, the way I deal with such issues now is to close them with a response that PRs are welcome (unless my specific config can reproduce them).

Also, extremely often you see open source as well as proprietary software on hn that's mac only. Isn't that, too, maintainers saying "switch operating systems"?

I don't think they are overclaiming. From the abstract:

> secret dependent control and data flows are completely linearized (i.e., all involved code/data accesses are always executed).

Their goal is to hide microarchitectural events from a passive or active observer. As a side note, the VUSec research group helped discover microarchitectural side channels such as Rogue In-Flight Data Load [0] and I'm sure they know the difference between earlier work on timing and microarchitectural side channels.

I don't think this takes into account the ongoing decreases in CA's current water sources. Some of those sources are shared by multiple, growing, states.

This seems to undermine any arguments about not requiring much water to support more people.

The fact that what constitutes “reasonable” and “technical” QoS is ambiguous and strongly dependent on popular opinion is a huge design smell for net neutrality legislation.

Ask HN: How a junior can handle a big bad coded project
Hi, I think a bit of context is needed to understand my concern.

I started working 2 months ago in my first job as a programmer in a medium-sized company, before I had only done personal projects for 4 years. I live in a place where there is little work of this and much less that they hire you without regulated studies as is my case. So I can't afford to lose it until I gain some experience.

They are assigning me quite delicate projects: making the cart change its price dynamically taking into account payment methods, and so on. At the same time they are wanting me to refactor how the order lines are processed to generate orders to suppliers or take it out of the warehouse, etc.

Some points that I find worrying added to the above:

- The way they have to upload to production is by taking the modified files in your project manually looking at the git log and uploading them manually with Filezilla renaming the original file with .old

- My supervisors don't check my code

- The project is too big to understand and is mainly written to barely hold

- I have to learn the logic of the company mostly on the fly because they give me vague explanations even when I ask for it

- The code is not documented

I would like to improve as much as possible as a programmer and do things with the least possible errors to endure as long as possible, but it is costing me a little more than I thought. I understand that I cannot demand much more of myself because it is a complicated project but I am afraid that my supervisors do not see it that way because of how they talk to me when I break something.

They have 2 years of programming experience and I suppose even less as supervisors / managers.

I wanted to ask you for advice on how to manage my situation and do my job as well as possible, I would greatly appreciate any advice or comments.
suspicion of editorializing

Not editorialized, but likely transcribed from one or more interviews and the interviewee and interviewer edit lightly.

There are people who couldn't write something like that given weeks but get them to start talking and they do a marvelous job. Drawing that out of people is one of the things that marks good interviewers.

Only newly deployed sats are (briefly) visible after launch. Most of the constellation is invisible to human eye at any given time, basically once the sats are on the operational altitude. Also while I would actually find sky full of bright sats all nigh long super cool, unfortunately not everybody does, so SpaceX is making the sats as dark as possible.
So much FUD and derailment in that GitHub pull request, wow. Hundreds of comments talking about names for forks and alternative software.

The original PR description absolutely was not explicit enough, and they probably shouldn't have went with a third party data processor in the first place, but the way they are trying to handle it is sensible in my opinion (opt-in, ask only once, disable the code path otherwise).
> Her politics seem broadly comparable to the majority of young Muslims (say, born > 1980) I have met in cosmopolitan American cities.

Which represents a very small fraction of all American Muslims. Also, note that in “cosmopolitan cities” you’re probably not interacting with a representative cross section of Muslim Americans.

> Should such people not be allowed to participate in the political process?

This is the third post where you try to turn it back to the politician, when I repeatedly make clear I’m talking about the media. These people are welcome to their politics. My problem is with the white people who control how Muslims are portrayed politically. Whenever you see a panel of Muslims speaking on issues, for example, they are always selected to agree with white progressive views. They never sound like my mom or aunts.

After leaving SF for 6 months I came back here to see if the housing market is better. I’m here for a month in an Airbnb. I just visited a place that was 4600$/month, 2 tiny bedrooms and all the windows gave on the landlord’s patio. Not like a nice patio, some small space surrounded by buildings, and not like I could see them, I could literally open my window and walk in their patio.

I just visited another place today at 5k/month with good location but not rent controlled (so they can pretty much double your rent at will) and the laundry isn’t even in unit. I still have to pay for a parking space.

At least it’s not a “tandem” parking, which I’ve been offered a lot these weeks. If you don’t know what a tandem parking is: you have to coordinate with another person because one car always block the other. It’s usually 250$, or more.

So right now I’m thinking, why do I want to spend so much to have the privilege to live in this city. It’s filled with homeless, it’s cold all year long, there’s a month of pollution every year due to the wild fires, and there isn’t that many things to do compared to a real city like new york. They don’t even have pedestrian streets or terrasses/patios/beer gardens (parklets are ridiculous).

So now I’m really considering moving to san diego, or nyc, or somewhere else…
Another reason not to work at Tik Tok is that they are simply not to be trusted with their size and influence. They are very aggressive with their censorship. It’s surprising given that they are based in China, but I’ve seen them ban content that goes against American progressive views more aggressively than even Twitter or Reddit or Facebook. For moderates and conservatives, it means this giant network amplifies everyone else and suppresses them. In other markets they implement different policies that are similarly aggressive but with different biases. Their practices are unacceptable and tech workers shouldn’t help bolster such anti-free-speech organizations.
If you don't encounter the justice system then almost nothing on your list is relevant. Most black kids won't be directly affected yet they do much worse at school. What specific examples of systemic racism have been shown to cause that? I've read some of the research and it's inconclusive. Many possible causes are suggested, a big one being cultural factors of the mothers.

So a normal black kid can safely pursue life without worrying that he or she has been held back by systemic racism.
>no. The Russian and Chinese planes with those engines can't supercruise. Thus they either use afterburner - short range - or go slow.

The WS-10C engines for the J20 are of equal power to the F119 engines of the F22. They cannot supercruise indeed, yes, but neither can the F35. The J20 is however larger and less aerodynamic and the engine probably has different trans-sonic characteristics and thus cannot supercruise despite being as powerful as the F22.

>exactly - the engine for stealth plane needs to be stealth itself. That means a bunch of technical solutions and limitations (like hiding the turbine from the radars looking from behind the plane, lowering IR signature, etc.) which complicates the engine construction and may clash with for example the power requirements to supercruise.

There is no rear-aspect stealth for any aircraft. The F22 has a 20-25dB higher RCS from the rear than the front, enough to make it plainly detectable. The same will be for any airplane, including the J20 that seems to have a similar drop in RCS from the rear. As for IR signature, this is simply not known. Modern IR sensors can already detect heat emissions from air friction, and lock onto planes even with their engines fully turned off.

I know this one guy that disagrees with me, and I think he is very stupid. This is proof that everybody that disagrees with me is also very stupid and wrong. The problem is that the opinions that disagree with me are allowed to exist.

Would cheaper/larger launch vehicles significantly change the economics of deploying space based observatories? The James Webb space telescope has cost about $10 billion, and you can afford even today's largest/most expensive launch vehicle (Delta Heavy) for a relatively small fraction of that ($350M).
Isn't that just sales tax?
The funny thing is that Silicon Valley was literally built on top of orchards, and in the process created several Superfund sites that have made the soil unsuitable for orchards. And then paved it all over with the awful suburban sprawl of 1970s planning that has created little opportunity for more environmentally friendly non-car-based development, despite being one of the best places in the world to not be in a car and instead be out walking or biking.

I can't come to any conclusions, I'm just struck by the irony of it all.
Yes.

Yes, 10K isn’t a lot, and the big apps are included in the 10K.

But… companies like Google Need as many apps as possible to funnel data to them so they can profile _everyone_, and they do that with their “free” services like Firebase (aka Google Analytics), in addition to ads.

To Firebase it’s all about scale (aka visibility) and not specific groups.

Shameless plug. I wrote a piece about The State of Open Data Portals https://uxdesign.cc/designing-open-data-portals-for-governme... where I predict that it'll take a Google to really provide a single searchable dataset portal for the whole world.

Doesn't take a genius to predict, but there ya go! Governments are assembling datasets in a very fragmented way. It'll take a private company to provide one single website to explore and find all datasets from around the world, making it easier to look at holistic patterns that are happening around the world, or compare patterns between countries.

Though, I would expect a much better UX from Google nowadays. This site has more in common with Google Scholar than Google Search.

And ultimately I'd like to see them build something where people don't need to download datasets in order to make use of the data.

I compare the state of open data to the state of mapping software before Google Maps. You needed to download map files and open them on special software that you open on your computer to make sense of the data. And then Google Maps came along and flipped that whole model. Open data needs the same leap forward in order for more people to make greater use of open data.

To put that in perspective, $2.9M in uranium is nearly 50 tons of "yellowcake", aka U₃O₈.

But! It takes ~780 lbs of uranium ore to produce one pound of yellowcake (worth about $30).

So $2.9M in uranium ore is about 39,000 tons. Is that a lot?
