Do you have trouble discerning "cobble" vs "coddle"? Maybe; how about with context? "We cobbled together some crazy hack," vs. "We coddle our infants to show love and affection."

Arguably this comparison is quite similar to your "((<]):) and ((<[):)" example. Certainly the relationship between "]" and "[" is the same as between "b" and "d". Kids first learning to write often do mix up "d" and "b". The difference certainly seems subtle and arbitrary in the first stages of study.

Do you have much experience in APL/J/K?

As I see it, the point is that these languages offer some really spectacular ergonmics and expressibility _once one has gained fluency_ and in a way not possible elsewhere.

This is really surprising! Perhaps that's why there's a lot of initial skepticism.

In the space of all possible programming languages, it certainly seems like we've explored a pretty darn good chunk. There are thousands of languages trying out myriad different possibilities. We have everything from C to Java, from Haskell to Scheme, from Forth to Bash, and this still doesn't do justice covering all the paradigms and methodologies we programmers have dreamed up. Is it really possible that there's some random corner of language space that offers something more than localized and incremental benefits? Is it really true that there's some wacky scheme for writing code that is way shorter to write, pleasant to read, while also running fast?

The answer is yes! And that's super cool! The catch is that it's a really weird family of languages, but if you spend the time to learn them well, I suspect that you will also see what we are talking about.

That disagrees with all the information that has been coming out of Italy for the last three days.

Perhaps because hospitals there (and in general) are always running at 80-100% capacity, so it didn't take much for the extra COVID-19 cases to max them out.
If a law is morally wrong and you commit civil disobedience you have no moral obligation to be punished for opposing the immoral. That would be silly.

It may be that opposing the immoral law and accepting punishment has a better marketing aspect for convincing people of the immorality of the law, but doing that convincing might not be the purpose the person has, their purpose might just be opposing the immoral law.
Huawei expects China to have 50% of the world’s 5G base stations by end of 2020
This study fits a two-variable linear model to a high-dimensional nonlinear process.
The paper describes how virologists in Wuhan engineered a "SARS-like" virus -- previously limited only to bats -- specifically to make it infective in humans via the ACE2 receptor. That's the same receptor used by the SARS-CoV-2 bug we're fighting now.

Note that the paper was submitted 12 years ago. They've had a lot of time to work out the kinks, if they were so inclined.

EDIT:

I want to repeat what I've said in other comments, because what I initially said was inaccurate. These researchers didn't actually create a new coronavirus, but rather a much simpler and safer virus purpose-built to test some receptor-binding structures.

This is a well-established way to study viruses safely, and this kind of work is critical if we're to learn how to develop vaccines faster in response to epidemics.

Key points:
People are spreading the virus before they start to show symptoms. Real number of cases is 10 times known cases. So if you think there are 100 cases in the country there are actually 1000, and, with a doubling time of 6 days, in a month's time there will be about 20 000, and on it goes.

Kids, in particular, fail to show symptoms and are infecting their elders.

This is one of the real dilemmas. Do we send them home from school, to reduce the kid-to-kid infection rate? Also, they need to stay away from their grandparents. But that will then require nurses with kids to be home to look after them. Who will then do the required testing and nursing in the health system?

We all have to practise infection control:

"The current scientific consensus is that this virus can be spread within 2 meters (6 feet) if somebody coughs. Otherwise, the droplets fall to the ground and don’t infect you.

The worst infection then becomes through surfaces: The virus survives for up to 9 days on different surfaces such as metal, ceramics and plastics. That means things like doorknobs, tables, or elevator buttons can be terrible infection vectors.

The only way to truly reduce that is with social distancing: Keeping people home as much as possible, for as long as possible until this recedes."

Soap, hand sanitiser and bleach destroy viruses.
Not sure what you mean about lying about prices.. I've booked 28 stays on 5 continents since 2014 and never been lied to.

Do you mean having to click on "price breakdown" to see the service and cleaning fees?

Do you mean hosts asking for cash payments for things like linens and key deposits? (These have happened to me, but it is against ToS and Airbnb took my side)

My current travel plans are chaos due to cancellations. We have up to 10 flight segments over a month away that we are eating 100% of the cost on due to a cancelled cruise. We are dealing with 3 airlines with multiple hour waits and confusing policies with no success so far.

AirBnB, by comparison has been a total delight. In the app, I push the "cancel" button, and it's like "yea, that's months away, no problem here's 100% to your credit card today"
I use both hotels and Airbnbs a lot. Price difference I noticed really depends on the location and also changes over time. Also depends on how many people are traveling in the group and duration of stay.

For example we were down in LA last month and picked a hotel for the night because the prices were about the same. However in Bangkok late last year staying at an Airbnb apartment was significantly cheaper than a hotel (roughly 1/3 the cost for the duration).

We're in the middle of this in Seattle - service workers aren't being called in, or are getting laid off.

And if you aren't in either of those categories, you should have a friend or relative who is, who you can ask to childsit.

I didn't read it that way and I'm on the left..

I've participated in civil disobedience protests before (forming a human chain.) Obstructing passage is illegal, but I believed in what I did and was willing to accept detainment.

The poster's perspective is that civil disobedience is illegal (almost by definition), and as an illegal action it has risks (detainment, being roughed up), and the willingness of people to take those risks for a cause they believe in makes them stop and listen. This is precisely the goal, and I laud them for not tuning it out!

Anyways, it can also go the other direction. The self-immolation of a reported Falun Gong member turned public opinion in China against the practice as too extreme/cultlike, bolstering the crackdown, rather than drawing sympathy for their brutal suppression.
Certainly. It is far more time than what our recruiter would put into it; but I don't see resumes until they've at least been filtered that way, so I don't really have to deal with a deluge, just a slow trickle. We're also a relatively small company, so the number of applicants is a bit reduced by that.

If I can find prior art that is effectively their patent, it shows to me that they were engaged in patenting something that shouldn't be patented. I have strong personal feelings about that, and I do not much want to work with someone that believes that every idea that _can_ be patented _should_ be patented.

With that said, there are many other reasons I would reject a candidate before I would reject them over this. If anything, with the relatively small number of resumes that I get on a weekly basis, anyone having any patents on their resume is going to raise a red flag that I am going to poke at more. It also gives me another topic to engage the candidate on, and on one occasion that lead to a conversation that made me vote to hire the candidate.
It's a fair criticism when there's some restrictions on supply. In SF about 1.5% of housing is on AirBnB. Is that tiny? Lots? It's probably not enough to move prices either way.
Thanks for the reply. I would be very interested if you could point me towards any private companies providing these kind of database solutions. I am particularly interested in their story around concurrent ingestion + analytics workloads. This is a tricky problem that most existing works solve by either doing stupid things a la. having a single-version system, or by using lots of synchronization + complex version-friendly concurrent data structures. Solutions I have seen in academia are usually tested well below the 1TB of data range, and I don't imagine they scale to the kind of data sizes you mention.

The fact that the research is being done outside of academia and not being published is pretty sad imo. Hopefully those in the know decide to publish at least tech-reports/whitepapers once they have a share of the market.

No, they didn't just study it. They engineered a variant of a SARS-like coronavirus specifically to be able to infect humans. The paper's abstract says they did this by "combining a human immunodeficiency virus-based pseudovirus system with cell lines expressing the ACE2 molecules of human, civet, or horseshoe bat."
Yes, you got the gist. Heads, it's _peer reviewed science_ and we get social programs/consulting business/corporate training based on it. Tails, well, the _specific_ experiment may not replicate, but the basic idea clearly has intuitive validity, it's well-intentioned, you'd have to be a monster to deny it.

Rust has Editions, so deprecated features can slowly age out of the ecosystem. People using, say, the 2015 edition will probably eventually want features introduced in the 2018 edition, and they will have to remove their usage of features that were dropped in the 2015->2018 edition bump. And if they never want any new features, maybe because their library is totally complete? Well, crates using 2018... can still depend on them, they just can't use those features.

I just typed "Aeron" into Craig's List and chose a seller. I think they delivered out of San Mateo. The going rate seemed to be $300 - $400 depending on whether you needed delivery or not.
I’ve met a lot of people (and got to know them intensely) who seem to not allow themselves to learn new things in specific areas (or maybe a lot of areas), while being proactive in others. Looking at myself, I had a hard time learning and maintaining interest about building physical things, or doing home improvement (all things where I need a hardware shop from).

My theory is that active discouragement during childhood is a driving factor here. My father often yelled at me if I broke something physical, or asked „stupid“ questions while building an RC car together. He also wanted to do all the home improvement stuff alone, and never actively explained anything to me there. So for me, home improvement equals discouragement, resulting in a feeling of I-can‘t-do-that.
(This kind of thing seems to be passed on - my father‘s father also shouted at him when doing something wrong).

On the flipside, my father at some point bought a PC and let me play with it, and seemed to not have any concerns whatsoever about that. He got some floppy disk games for me, installed the office suite, and let me have at it, sometimes grunting encouragement.

Now guess what my favorite activity is, and what I built my career around - home improvement, or computers?
I wonder why callbacks aren't a more popular way for languages to handle exceptions. What if each type of exception registered a weak link to a function with a name like `IOExceptionHandler` which prints a noisy error if it isn't overridden with other behavior?

I guess it would be harder to use a single exception callback if you had a lot of similar "try/catch" blocks in different areas of your code, and you'd still probably need to collect some sort of stack trace, but it might work out alright if you go with this article's advice and recommend that people keep exceptions out of their program's normal control flow.

I dunno, maybe it's a dumb idea and I've just been spending too much time with microcontrollers lately. They use interrupt callbacks for all kinds of hardware triggers and software events, and I kind of like how you can compartmentalize error handling into a few predictable event handlers.

That Java stack trace image at the end of the article also brings back some memories...but I'm feeling much better these days.
So yeah, I don't buy the AirBnB has failed thing, because I'm a heavy user.

AirBnB hasn't failed. It has plenty of users, and over $2bn in revenue. That's not enough though, because the costs of running the business are higher than $2bn and so we see articles about how it made a loss again.

It seems fairly clear to me that a large number of loss-making unicorn companies need to get their costs under control, and the obvious way to do that is to lose some staff, or pay them less. At the moment that's hard because there's enough competition between companies that people can choose where to work but eventually the need to cut costs will outweigh the need for "the best people", and salaries for new jobs will start to fall. The result for many developers will be that they have to either stay in their role for a long time or accept a pay cut to move company. It might be worth considering that possible outcome if you work in dev right now.
I have looked into this in some detail doing deployment studies for wireless HART instruments (industrial processing plant gear) which can talk to a base station or store and forward for a friend.

So depending whether you want broadcast or point to point, or in between, performance is dominated by "pinch points" which is such an obvious term that I wont describe it.

This means that a groups situation in this context could be dramatically improved by a unit or two in a balloon or drone above the group or similar.

I suspect in practice when deployed and medium sized groups use these that a "signals master" or two will have primary responsibiliy to maintain such nodes to keep effective comms up and might use kites, balloons, drones, terrain, whatever and a particular set of skills and equipment would develop.

Also, if any given unit can impose a "cost" relative to business, amount of battery used etc then self levelling and incentive to be terser with messaging can occur. Lets face it, when you are down to 3 bits a second the use of emoticons will drop off pretty quickly.
Same nonsense we were told in 2008. The financial stuff is far too complicated for us mere mortals to judge, leave it all up to the bankers. All of this despite the fact that economics is a corrupt pseudoscience.
I have yet to see any solid evidence for this idea that children are significant sources of infection. Children tend to be less symptomatic, and while asymptomatic transmission almost certainly happens, every source I trust says it is rare and the main cause of infection is close proximity with someone who is showing symptoms.

> I’m not sure this is that weird.

The parent is correct. Bond prices and stock prices moving together is not that weird at all and often happens during market disruptions.

WSJ ran a piece by James Mackintosh a few years back that pointed to the changing relationship between bond yields and stock prices as a potential sign of trouble: [1]

“A generation of traders have grown up with the idea that stock prices and bond yields tend to rise and fall together, as what is good for stocks is bad for bonds (pushing the price down and yield up), and vice versa.”

“This summer [2016], the relationship seems to have broken down in the U.S. Share prices and bond yields moved in the same direction in just 11 of the past 30 trading days, close to the lowest since the start of 2007.”

“This is far from unprecedented. But since Lehman Brothers failed in 2008, such a swing in the relationship has been unusual and suggests prices are being driven by something other than the balance of hope and fear about the economy. It has tended to coincide with times of deep discontent in markets, notably the 2013 “taper tantrum,” when bond yields briefly surged after Federal Reserve officials signaled they would soon end stimulus, and last year’s brief bubble in German bunds.”

That said, the severe erosion of liquidity described by OP is real. An article from MarketWatch today goes into more detail: [2]

“During times of intense volatility like this week, dealers will demand a hefty premium to trade off-the-run Treasurys, as it could be difficult to take them onto their balance sheet and offload them again to a willing buyer.”

“On the other side, mutual funds and other investors promise their clients that they will be able to pull money in and out of funds on a day-to-day basis. These investors who have seen their off-the-run Treasurys holdings record double-digit gains in the span of a few weeks are now trying to sell their bonds and book profits, said market participants.”

“This mismatch in demand has led to a surge in the difference between the prices offered by buyers and the prices sellers are willing to accept, or the bid-ask spread, for off-the-run bonds.”

But I actually remember a lot of the hotels I've stayed at. It's the Sheratons and Marriotts that blur together. They're perfectly fine hotels, they're just all the same.
I don't think options really serve the same purpose as exceptions. If you have are just passing up None or whatever up the call stack over and over again, you probably should just be using an exception. If not, then options are fine. I use options for normal behavior (a missing file, for example) that perhaps can be corrected or handled in a different way. I throw an exception if I want to just crash the program. I rarely ever try catching exceptions, except in maybe some top level driver function. Oh and to all the programmers out there who wrote the code I'm currently dealing with: please don't use exceptions for flow control, it's a terrible terrible idea.
Excuse my ignorance but would a colder temperature but with rain help prevent due to the high humidity or does it require heat AND humidity?
> not once have I seen an explanation of what makes it fast and why those techniques aren't looted for open-source languages

The language design is such that the programs you write can make optimal use of cache and SIMD. The interpreter can only take advantage of that if the language offers you that. It's like saying "not once have I seen an explanation of what makes c so fast and why those techniques aren't applied to python and javascript."

(Note also that the reference J interpreter is opensource and very competitive, performance-wise.)

> The most expensive meal a person ever ate was in late 2019, in China, and consisted of under-cooked bat meat. It cost trillions of dollars. The person who ate it, possibly a peasant, changed the course of the 21st century. The bat he ate contained a virus, and the virus threatened to spread from this man to the rest of humanity.

Is there any evidence for the suggestion that patient zero consumed bat/pangolin meat, or that you need to consume bat/pangolin meat to get infected (as opposed to say, being near them)? To my knowledge this is still a speculation [1] and there is no concrete evidence. Linking coronavirus to Chinese culture and food habits will only lead to more Sinophobia. I'm also not sure what the author is trying to accomplish by talking about the Holocaust.

I am getting downvoted here without anybody actually addressing my arguments - TFX/Beam being replaced by TFX/KubeflowPipelines and the new platform being plugged in tightly to Google's managed services (AI platform, BigQuery, GCS, etc). I didn't think my tone was negative - they are observations that nobody in this subthread is addressing.
As a systems person, TFX to me was a layer on top of Beam to tie ML pipelines together. Now, Beam is gone - dataflow appears as a managed service you can use in your pipelines (see the figure on the blog post). TFX is being repackaged as the API for Kubeflow pipelines. That was my take and what i wanted to discuss.
