One insight that may help non EE educated people understand what an antenna does: The simplest form of an antenna would be just a simple point emmiting electromagnetic waves. These waves would be transmitted all around that point distributed as sphere. All points of a sphere will have the same power. Now, an antenna has a different geometry than a point that helps somehow "focus" the EM waves, so their power is not distributed around the sphere uniformally but some directions get more power depending on the antenna design.

Now the thing to keep in mind is that an antenna is a passive device. It does amplify the signal but it does not add any power to it, it just collects the power to specific points. This may be easier to understand with a receiving antenna (which collects the signal).

For example, consider the satellite dish which is of course an antenna. Due to its design it should be conceptually easy to understand that the power of the transmitted field is all gathered in a very small area in the front of the dish. The largest the dish, the smaller the point where all the transmitted power is pointed, so less power would be needed to cover largest distances (and more difficult finding where the dish needs to point).
Only for now, because it isn't approved. If it is approved and doesn't have too many effects it should be much much more effective early on.

Thats one of the things that made the ARRL Antenna handbook so valuable to me; they have some solid advice on weatherproofing and dealing with things like wind and snow loads.

Its easy to make an antenna; its just a bent length of wire at the end of the day. Making it be the same length of bent wire today, tomorrow and beyond, when its mounted outside and /or in harsh conditions, thats difficult.

Honest question: in what way? As in it might make sense to have an omni-directional antenna for the transmitter but a directional antenna for the receiver rather than omni-directional for both?

I had a very similar situation with a tax collection system written in Oracle Forms around 1999 that we rebuilt in ASP.NET Core. We had a bit more leeway than your project, but essentially we kept the navigation scheme and placement of the buttons and content panes in the app exactly the same.

The big upside of this whole thing is we were able to swap the database from Oracle 11g to MS-SQL with no impact on users. Something that just wasn't possible with the legacy tech.

Also, I'm wondering at what point privacy-groups will start complaining about this sort of testing. In the future, the testing will get to a point where smaller and smaller parts of cities can be measured independently and that would yield policy-action by the government. E.g. "This area over here has lots of meth users, let's police that area more."

Or... They test everyone's sewage independently and privacy-advocate groups cry foul because sewage (and garbage) are personal information and the city can't use it to discriminate or punish people!
One article I read recently brought up a topic on how unreliable testing and confirming the dead are currently that to get a more accurate count we should look at year over year deaths. This could be broken down to compare deaths in a county the last x years in March to this year.

Everything from their standards compliance to their change control should be regulated,same goes for mozilla.

I have wondered whether there is room for a new paradigm in government IT contracting: the worker-owned public benefit corp. The focus would be on building and applying “open first” government solutions.

This type of entity would feel to employees like a tech company and look to governments like a firm such as Mitre. Direct compensation would be higher than direct government employment but less than FAANG. Sort of like an “outside the house” 18F.

Definitely! And I think that's often symptomatic of other organizational issues. E.g., A lot of American business culture focuses on local incentives and optimizations. If a manager is being evaluated and paid based on metrics A, B, and C, how much can we expect them to ignore that and solve systemic problems?

The standard MBA solution to this is that higher-level managers must design ever more elaborate systems to correctly measure the right behaviors. But a) that's somewhere between hard and impossible, b) the people filling those positions are only human, and c) the average CEO tenure is ~5 years, and executive tenure in a given position is even lower, so there's not a lot of incentive for anybody to create a system optimized for long-term value.

Most of that is oriented toward yeast breads, but as a minor point that was confusing to me for awhile:

At least in the US, there is no technical legal definition for baking powder. So companies vary widely in what is included in baking powder. Ideally, baking powder would include a dry acid and base that react only in typical baking temperatures, but this is not the case. Some are very similar to baking soda in formulation, and others use different ingredients that require heat to react to any substantial extent.

There's an article somewhere I found that has a really great discussion of the issues, with history and reviews, but I can't find it. This is a sort of abridged version that smooths over some of the differences you'll run into:

In our hackerspace, using 3 antennas in an ubiquity "UFO" danling in front of a shelf, communicating 2~3m to a thinkpad with afaik 2 antennas, using an 80MHz 5GHz 802.11ac configuration, we get consistently >500Mbit/s (iirc hovering at roughly 600Mbit/s) (unidirectional) to the NAS (1000BASE-T wiring, 1-2 switches in-between) when mounted via NFS. A single stream can't get more than ~420Mbit/s _in the lab_.

> Avoiding taxes by legal means, is neither illegal nor immoral.

No matter where you stand in the hypothetical debates on taxation and public spending in the real world it boils down to government will spend tax money, taxes should adjust for the ability to participate and avoiding them just shifts the burden from people that should be able to afford them to others - I think this is immoral by most accounts. And IMO, arguing that it's not not worsens the problem, laws have a limited impact and will always have flaws - morality and social judgment (as absurd as these things are getting these days) are another correction mechanism for undesirable behaviour.
That's fairly cruel of you.
Scientific articles on Wikipedia aren’t written for laymen, although some could be understood by laymen as a side effect. For example as a physicist/mathematician I expect precise and physically/mathematically accurate statements rather than hand-wavy analogues that the average Joe might be able to make sense of, and that’s how I edit. Now, it’s okay to also include more approachable explanations, but they’re not a must.

I'm not so sure about that. I've read wikipedia articles about subjects I know well and found the language to be needlessly packed with jargon such that it could at least momentarily dazzle and confuse the inventor of the subject himself!

Rigorously precise language (e.g. "jargon") is almost never needed for a top-line description of a thing, and I think should be discouraged, in general. Yes, highly technical descriptions targeted toward professionals and academics in the field have their place in wikipedia, but ought to be relegated to periodic additions to the body of the article. That's just my opinion, of course, but as such I think its quite correct and admirably justified!

I don't think that works. It only takes 10% of defectors to create a similar catastrophic result as with 50% defectors.

Human society has enacted laws for about four millenia and enforces them with threats and violence. That works to keep those who would otherwise only act in their own interests in check. There was no group of humans at the size of Sweden's population in existence where toothless rules like "be excellent to each other" and "use your best personal judgement" were enough to be workable.
HN respawns on a daily basis.

Content on the home page is gone and new content arrives. Due to the moderating system it is not as if every story is hogged by the same people insistent on the world believing their viewpoint.

However, what does 'kill' HN for would be participants is nitpicking. It is easier to be destructive and to mod something down for a minor detail than it is to write something substantive. Some people may find life is too short for ungrateful nitpicking behaviour and go elsewhere where ideas can be shared and improved on rather than nitpicked.
I think the tone of this post is insufferable, and the arguments have little merit presented this way.

The alternative suggested is also non ideal, since array declaration/indexing is semantically different than a function call, not all languages have method calls, not all languages have postfix method calls, I can think of a few ways to break that syntax (what if the type has a call operator and indexing operator?), and it is hypocritical.

The problem with <> is that they are used elsewhere. If you use [] by sacrificing arrays, () will cause problems because they're used elsewhere.

The lowest friction solution would be to introduce a new two character bracket. How about <: or :>? (: :)? I don't know but writing about it in that tone won't get anyone to do something different.
> “It’s an excellent paper, and it looks quite convincing,” says Fred Spoor of the Natural History Museum, London. “It would have been ideal if there was more of the cranium, but I think they make a very good case that it’s Homo and that the closest affinities are probably with erectus. And that would make it quite likely the oldest Homo erectus-like thing.”

> “I have no doubt that they have something that is of the genus Homo,” adds Rick Potts, a paleoanthropologist and head of the Smithsonian’s Human Origins Program. But Potts notes that the incomplete skull doesn’t show all the telltale features that would characterize it as Homo erectus or some other relative. Furthermore, the cranium belongs to a 2- or 3-year-old child, for which comparisons are scarce. “I’m not 100 percent sure that they have Homo erectus. And that would be one of the really interesting parts of the study, because if they do have Homo erectus then it is the earliest known in the world.”

Depends on the polarization. You want the antenna at 90 degrees to the direction of the field. A vertical whip radiates horizontally, a horizontal whip radiates vertically!

The reason you usually put them vertical is so that you can use the Earth as a ground plane, leading to less wasted power. A horizontally positioned whip antenna will lose a fair bit of power to the ground.
“Only a Sith deals in absolutes”.

If businesses operated in a vacuum from politics, then maybe you could have an argument that taxes have “nothing” to do with morality. In the real world, businesses are lobbying for changes to the tax codes to benefit them, holding disingenuous or rigged contests to extract the maximum concessions from tax authorities, relocating or transferring intellectual property and licensing it back to subholdings to min/max gains and losses, and a myriad of other schemes.

To directly answer the questions you posed: Corporations which incorporate in a state like South Dakota or Delaware to take advantage of incorporation policies, with no intention of operating primarily in those states, the majority of their business conducted in a higher tax state like California, and trying to avoid contributing back to the society of the states that they primarily operate in - yes, those corporations are less moral. They are less moral than companies which are incorporated in e.g. South Dakota where the owner lives in South Dakota, and serves primarily South Dakota residents.

Hungary is harder to answer. Did the corporations of Hungary lobby for lower taxes which resulted in that tax decrease? Does the tax decrease adversely impact Hungary as a whole, or was there a budget surplus which allows the state to lower the rate? Does the relaxed rate improve the lives of “normal” Hungarians? The answers to those, and probably more, questions would guide the answer to the question of morality.

Anyway, this is a long winded way of saying that morality is not a binary choice. It’s the perception of right and wrong guided by context.
Pipelining in 1.1 has some issues, but it could be useful in the right circumstances (except that, there's not a lot of implementations of pipelining, so chances are the other end won't do it).

The perfect use case for pipelining is when the client is connected to a (reverse) proxy near to it, is making retryable requests, the origin is far from the proxy, and the requests don't take much time for the origin to process.

You can also get benefits if there is a proxy near the server and the requests take significant time to process, but the proxy can divide them over multiple servers (or the server handles pipelining and divides over multiple threads).

The way these usecases are met instead is through multiple TCP connections, or multiple multiplexed streams in HTTP/2 (and beyond). There's certainly benefits of individual streams, but there's costs too, so it's unfortunate that the http/1.1 way was stiffled.
