I saw it more that servo is the codebase they want firefox to be, but changing out the engine in a humongous codebase like FF is extremely difficult so they're taking it a step at a time. They merge bits and pieces in from time to time[0] and I expect that to continue until firefox is servo in as many places as possible.

Looks like servo might only be a breeding ground for ideas after all.

Really love how people are on Twitter and other outlets blaming this action on Trump already when it literally has absolutely nothing to do with him and he has opposed almost all action the Fed has taken so far. Social media and the hive mind read the title and not the information mentality is really getting tiring for me..
Yes, I'm wrong. I was thinking of the naïve implementation

if ( a < b ) then { return b } else { return a }

which requires being able to decide order, but, as child comments point out, that's not necessary.

There's backtrace_symbols, but to get decent info you need linker flag -rdynamic. I much prefer the stack traces from Rust, or Java (Apples to Oranges comparison there, as comparing a compiled language trace to one from interpreted language). For new projects needing a systems language in permissive environments I see no reason to go with anything other than Rust or Go, though there are other options that might be as good that I'm not familiar with. Unfortunately, there's a lot of legacy code (there are still people getting paid to maintain COBOL programs - not me though), and there are a number of restrictive environments where any technology newer than 8 years is a tough a sell.
That worked for about 45 minutes and then the market dropped right back down again. Incredible. At this rate there won't be enough liquidity to cover these sell-offs if they continue. I don't think that's ever happened before.
This is the key point I think: viruses have no metabolism. There is no stable energy transfer with their environment. Their genomic feedback does not promote metabolic growth (ie greater energy transmission rates).
The sad thing is that this still makes SF one of the better major cities around for public transit in the US.
Specifically, "the fed is a private bank" is a common refrain among goldbugs and currency conspiracy theorists, and it's not true, no matter how often it's repeated.

Not saying the OP is a goldbug or currency conspiracy theorist, but they're the only people I ever see tossing that out so quickly and without any elaboration on what they mean.
Single points of failure? Bitcoin is decentralized, like the internet. It’s designed to explicitly avoid points of failure and trusting of node participants.

Lots of Bitcoin has been lost. Good key hygiene should not be taken lightly. What is unfortunate for those losers is fortunate for Bitcoin. As the supply of lost Bitcoin increases the overall scarcity of the asset increases.

I'm not sure this is true, especially in the era of free-flowing VC cash and low interest loans.

I think the problem is that most developers did not learn OOP correctly. I noticed a lot of developers these days don't understand basic concepts like encapsulation and class dependencies.

When I was studying OOP at university, there was an entire course on UML diagrams and that taught people how to structure OOP software.
Good OOP design tends to produce elegant-looking UML diagrams with relatively few interconnections between components.

I don't always physically draw UML diagrams, but when I visualize a project in my head, it looks very much like a UML class diagram. I can't imagine how it's possible to reason about complex software in any other way TBH.

Sadly, if I had to draw a UML class diagram for most real projects which exist today, the relationship lines between UML classes would be crossing all over the place and it would literally look like a tangled mess (definitely more like a graph than a tree).
The people who designed the software had no vision for it, they just kept adding stuff without ever actually understanding how it all fits together or thinking about how to minimize complexity and make it more elegant by minimizing the number of components and the interconnections between them.

I think that, in a way, functional programming is more forgiving when it comes to allowing people to keep adding stuff on top without having to visualize the system as a whole. It doesn't mean that FP adds any net value over OOP. I would argue that being able to clearly visualize the whole product and the interaction of data and logic is essential regardless of what paradigm you follow.
Without seeing the numbers for tests conducted you're just wildly speculating based on personal opinion about the country.

From WHO stats in the last day China has 50 new cases.

Let's take South Korea instead, they have tested more per capita than anywhere else on Earth by far and conduct over ten thousand a day. Since yesterday they've had 100 new cases.

Sorry to disappoint the doomsayers but all these big grandiose predictions seem far off the mark with a proper response.
Agreed, true!

AC in American English just means cooling. In China, it usually means an electric air based unit that can cool and heat (central water based indoor heating is done via circulation, I’m not sure if gas heating would be considered AC but I’ve never seen that in China anyways, local coal based heating was also common but the government has cracked down on that).

A concrete slab built without insulation is going to be difficult to insulate after the fact, you just can’t foam it up because there is nowhere for the foam to go. You have to maybe build a false wall and lose some floor space, or use paneling. Anyways, it is complicated.

Zhejiang and jiangsu are China’s richest provinces, and often lack the problems of the rest of south China. Jiangsu is actually north of the Yangtze so they they get heat in the cities anyways, like much poorer Anhui next door. Hunan, Hubei, Jiangxi, and I guess fujian is where the no heat in the south starts to hurt. Guangxi and guangdong also, though winter weather isn’t as bad, but touring Guilin I the winter was also a bit uncomfortable, only the five star hotels provided real heating.
Fed to pump trillions of dollars into financial markets
And, for that matter, San Francisco is nothing to write home about.
Most of the "normal" people I know IRL have usernames like that.
$1.5 Trillion goes into a certain aspect of the money supply to help maintain credit spreads, etc. This is completely different than your agenda list expenses. If you flooded the entire US economy with $1.5 trillion in straight cash it would likely cause inflation, but the Fed isn't injecting it into that level of the money supply.
IMO, when people talk about OOP they aren't talking about bags of static functions -- that's just a namespace. The interesting objects are those which hold state.

The first US patent was for a method of making potash, for fertilizer.

The early US loom patents are particularly ironic as they were “stolen” from the British design rather than actually invented, in violation of British law. The same thing applied to a whole bunch of other early technologies - the patents existed to encourage stealing other peoples ideas and hard work then claiming it as your own.
As far as I can tell, the answer is quite simple: there was no WHO test at the beginning. The CDC's test was developed and rolled out pretty much in parallel with the German one the WHO has been using. They deployed it to state testing labs at pretty much exactly the same time as WHO Europe was rolling theirs out to one lab per European state. They also had a very aggressive plan to start testing flu surveillance samples in mid-February, much sooner than other countries. I'm not convinced they could pull off such an aggressive rollout without manufacturing their own tests.
He is taking his current understanding and coming to the conclusion that the mechanism by which soap renders viruses inactive is 'actually' because it destroys proteins. I am pointing out that this exercise is futile and does not result in useful knowledge.

If a domain expert says something that does not make sense to you, there is a small chance that the domain expert is wrong, but it is more likely that what the domain expert is saying is correct and your own knowledge is incomplete.
I'm not so sure. Ruby did a very similar set of breaking changes around the same time and it went fine. It seems to me like the main difference wasn't in the changes — it was that the Rails developers enthusiastically embraced the changes, which pushed everyone else to do the same, while Python had more of a diffuse situation where some library authors went for it and others didn't and it led to everybody getting cold feet.
One winner of an investment strategy is regularly rebalancing your portfolio to a set of fixed ratios between asset classes.

Let's say you want a 1:1 cash value ratio between stocks and gold. If stocks go up and gold goes down: sell stocks, buy gold. If stocks crash and gold spikes: sell gold, buy stocks. It's an easy way to buy high and sell low without going to extremes.
Two sentences later in the paragraph your quote came from:

>As an independent institution, the Federal Reserve System has the authority to act on its own without prior approval from Congress or the President.

And later:

>The twelve Federal Reserve banks provide the financial means to operate the Federal Reserve System. Each reserve bank is organized much like a private corporation so that it can provide the necessary revenue to cover operational expenses and implement the demands of the board. A member bank is a privately owned bank that must buy an amount equal to 3% of its combined capital and surplus of stock in the Reserve Bank within its region of the Federal Reserve System.

> Java's "never remove a deprecated API" was definitely one of their big mistakes. Even a 10-year deprecation cycle is better than none.

Can you explain this position? Python just did a 10-year deprecation cycle on Python 2, but it was really costly for a lot of people. If they'd just not done that it would have been better; the benefits of removing stuff are relatively minor (cleaner language implementation codebase) and the costs are huge (all users need to change, test, handle compatibility, ...).
Then it sounds like there's a missed opportunity for some clever person to develop a better system for these customers to use.

The other way to think about it is the difference between 'clean' and 'sterile'; having no influential chemicals present (clean), and having no living units capable of replication present (sterile). They are actually different concepts that are caught up in the generic concept of 'clean'.

A surface full of massacred microorganisms might be 'sterile' - nothing there can support life, even if given sugar, water, energy, etc. But it's also certainly not clean. If any of the debris from those dead microorganisms could trigger your immune system, were poisonous, or were chemically active they could alter the outcome of a chemistry experiment or trigger an immune response.

Disinfectants by definition kill organisms, but don't remove the constituent components of the organisms from the area. Bleach & alcohol in high concentrations (but not pure!) will also destroy most any organisms (but will not in itself remove the debris of those dead organisms).

Soaps will link chemicals and molecules to water that is flowed over them, and will remove all of those constituent components along with the water. And if the soap is strong enough, it will also dissolve and destroy smaller organisms in the process. A surface washed with soap will no longer have any debris on it.
> That makes sense, as the term originated with UI development that predates HTML.

Yes, but this post is focused on HTML which is why I phrased it in terms of HTML. The term "dropdown" is often used to describe a desired out come (a method of interaction in order to make a selection) and is often meant independently of the actual implementation, as browser, for example, will implement the control differently based on platform.
>That's not what I said, in fact the study does the opposite.

The study explicitly says it's lower risk because it's investing a lower amount.

If there's a negative risk premium, then any strategy that invests less will automatically do better. But lump-sum will still do better than DCA with the same amount of exposure, since it's still better diversified.

I like the balance you achieve. There's a big difference in what you put out into the world and what you let the world do to you.

I highly value respect, politeness, and decency. Interactions with other people shouldn't suck by default. I actually try to be nice.

I just place no value on others being nice to me. I care much more about do they treat me with respect and decency? Are they honest?

I believe valuing "nice" in and of itself in others is exposure to shitty people. If you value people simply because they are nice, some of them will inevitably take advantage of you.

You are missing the key trick - hedging!

The person who sold the put to you can short some shares and lend out some money to create a "replicating portfolio" that inversely mirrors the payoff of the put option they sold you. They're making a small % on selling the put and then immunising themselves from the market movements.

Who lent them the stock to short? Index funds! The people who want to make market returns, still do. Everyone is happy

I worked for Columbia/HCA, now HealthCare of America, at the time and we started gearing up for Y2K in January, 1997.

Every system, every piece of hardware - both in the data centers and in the hospitals - had to be certified Y2K compliant in enough time to correct the issue. As I recall, we were trying to target being Y2K ready on January 1, 1999 but that date slipped.

A "Mission Control" was created at the Data Center and it was going to be activated on December 15, 1999, running 24 hours a day until all issues were resolved. Every IT staff member was going to rotate through Mission Control and every staffer was going to have to serve some third shifts too.

I left Columbia/HCA in June, 1999 after they wanted to move me into COBOL. I had no desire to do so and I took a programming position with the Tennessee Department of Transportation.

I remember my first day on the job when I asked my boss what our Y2K policy was. He shrugged and said "If it breaks, we'll fix it when we get back from New Year's".

What a difference!!!

Supposedly the plan in the UK (not for the NHL, other sports) is to ban pubs from showing them, but play behind closed doors and dish out 'free' streaming to ticket holders, so they can watch at home even if they don't usually have access.

Using a very rough ballpark estimate, it costs $1 / month to run a twitter bot using readily available technology, see, for example, https://jarvee.com/get-now pricing list. To think that for $50k / month anyone in the world can have a [significant?] impact on US elections is bizarre.

In practice, there is a negligible probability that posting a tweet from a random bot will end up in the feeds for a target demographic. The feed space of the 80k people WP claims decide the election is finite, and it costs significantly more money to reach them than setting up small scale botnets. Ultimately, Twitter is in control of the feeds, and it's their business model to happily direct any message from the highest bidder to the critical demographic, regardless of who or where the highest bidder is.
Liquidity isn't everything. What makes USD bills any better than Hasbro dollars? Why are people trading dollars over the internet when they could be just trading packets, which are infinitely more available (liquid).

You're missing an important piece of the puzzle. People want to trade for something that they perceive to have more value than the thing they are trading. This can't work if you have an infinite dollar printer (or magic numbers somewhere on the internet) because the money will be perceived as worthless (or will become worthless in the not so distant future).

The future is being able to trade something which is perceived as holding (or accruing) value which can't be arbitrarily reduced by policy-makers, and also is highly liquid, difficult to forge, easy to verify, low-cost to transact, and can be used as payment for most services. Any guesses as to what this might be?
> Which languages would you say are really good for defining your own types? Would they be a good fit for the example I provided where a function needs to accept integers larger than zero?

I'm not an Ada expert, but it has excellent support for range-restricted integer types.[0]

Ada's 'discriminated types' are also fun. They let you create members which only exist when they're applicable. [1]

> Do they also allow you to define your own operations on those types

Looks like Ada supports operator overloading, yes. [2]
