I'm actually pretty much against UUoC. The cat example is much more resilient to modification. For instance, there are usually natural modifications considering filtering etc.

Anyway, since he said number we probably want `nl` not `wc`.

Separating pipe-setup from processing is sound engineering to me and makes things much easier. For instance as I iterate, I will have cat piped to head piped to filter but eventually I'll take the head out and run the whole thing. That's a trivial ^W versus moving around arguments and worrying about arg order, etc.
To evade taxes, probably.
This is a complicated discussion because the relative performance is greatly impacted by design and implementation details. Broadly speaking, the execution engine and page representation designs are tightly coupled for performance optimization purposes. The kinds of optimizations outlined at the link will have a high return for most kinds of databases.

The term "columnar" covers a diverse set of architectures with very different operational characteristics. For OLTP (like CockroachDB), using a classic DSM-style columnar representation is going to offer poor write performance no matter what you do with the execution engine. On the other hand, if you are using one of the newer vectorized page representations (VSM) that are popular for mixed workloads, which are quasi-columnar but not DSM (nor one of the intra-page DSM hybrids like PAX), the loss of write performance may be minimal versus a classic row store (NSM) but with much faster query processing (faster than DSM for some types of queries). The execution engine design you would attach to any of these models is pretty different.

Note also that a practical limit on this kind of optimization is code complexity. While VSM-style on-disk representation and matching execution engine sounds like a nearly optimal hybrid of both NSM for write performance and DSM for query performance, an implementation that is general purpose and performs well across a diverse set of data models is massively more difficult and complex to build in practice so most database designers avoid it at all costs due to the engineering overhead. These tend to be more common when the set of supported data models are very limited at design time. It is a research area that still offers a lot of opportunity -- the literature mostly ignores parts of the productive design space that intrinsically have extremely high implementation complexity (too difficult to produce code in support of paper publication).
> A lot of those parts are from third party suppliers (not that it excuses Tesla completely of course).

What makes you think that other automaker aren't using third party suppliers? Borgwarner, Denso, etc... are all third party suppliers that many company uses.

After the recession of 2008, many third party suppliers went bankrupt. There is a consolidation of third party so now many automaker share similar parts among each other.

Even the new Supra, Toyota tested the BMW engine and ask BMW to change some stuff.

It still up to Tesla to test the reliability.
It's an interesting issue. My start up is in the healthcare space, primarily in the USA although I'm currently based in London. Theres definitely a group here who think that NHS users just need to accept that their data is going be fed into models and its part of the price of universal coverage as it will help outcomes and costs etc. I'm still on the fence about it, but having seen some of the results that AI is catching out in the field I'm tending towards universal good over personal privacy - though I may regret that... Im thankfully that at least the data cant be used to adjust individual insurance premiums.

As an aside, it is not just Deepmind/Google, all the players are trying to get all the EHR data around the world. The NHS is particularly attractive due to the volume of historical data of course. Its no secret IBM Watson is working with NHS Wales although I don't know what data sharing agreement is in place.
When you download an app through a browser, it will set a quarantine file system attribute. By default, clearing this bit requires the app to be notarized. The user can also right-click open to allow an app to run, add a third-party certificate as trusted, or disable Gatekeeper altogether from the command-line.

I believe Catalina also will be periodic checks to make sure the binary hasn't been modified.

If you don't distribute software off of your own machine, you do not have to think about signing at all.

The rust installation manager and cargo do not set the quarantine attribute, so there is nothing for quarantine to check when binaries are run.
Couldn't this be curbed by better radiation shielding on the plane itself?
What do you use in-car wifi for, that you couldn't already use your existing unlimited cell data plan for? I have unlimited data, plus "unlimited" hotspot on my t-mobile phone for a really reasonable price (the unlimited hotspot throttles down after a certain point, but even that speed is still plenty for what I used it for -- I only which I could explicitly tell it I want to use the throttled speed gigabytes now, and save the high-speed gigabytes for when it would be useful).
"Remember that code is really the language in which we ultimately express the requirements. We may create languages that are closer to the requirements. We may create tools that help us parse and assemble those requirements into formal structures. But we will never eliminate necessary precision—so there will always be code", Robert C. Martin, Clean Code.
many destroyers (including world war 2) have only forward main guns (usually 1 or 2). I can only speak from my experience playing naval ship games. Destroyers are very small but nimble ships. if you need to fire from aft guns, you already lost. Space is precious, better to have something like a helipad back there than another gun you'll never need, in my limited opinion on naval ships.
Those are common in U.S. hotels but virtually unheard of in homes. Most U.S. homes have separate hot & cold knobs running through a single faucet/showerhead, with a knob or switch to select shower vs. tub. First time I ran into the single-control shower, it took me a while to figure out how to work it as well, and I've lived in the U.S. my whole life. It was pre-YouTube as well, so I just had to fidget with it.

I've seen the thermostatic faucets before (I assume those're the ones where you twist to adjust temperature & pull to adjust pressure). They show up in more modern upscale hotels, and in people's homes when they've remodeled their bathroom. I think they tend to be an aftermarket add-on rather than a typical part of construction, though - no idea why, they're much more convenient than the alternatives.

Being a product owner and using a Kanban board daily, I “lost” half an hour with your game. Nice work and as others have suggested, polish it up and release a game.

A few comments/suggestions if I may (playing on iPad with latest iOS):
- include the same icons in the swimlane titles as the ones you have on each resource
- ability to rearrange resources
- make swimlanes scrollable so that we can see all tasks
- add a random timer of sick/vacation unavailability for each resource
- resources gain experience/competence with each task they finish
Yeah, but the sea was calm and the weather looked fine on the booster landing video from the platform.
After the first Starlink launch, Musk made a number of comments about being willing to experiment with launching some telescope-equipped Starlink sats since they expect the per-sat costs to be so low.

If you had dozens to hundreds up there, you could probably do some useful interferometry even with small telescopes.
Have they given a range on latency goals? Ie seconds, tenths of seconds, milliseconds, etc?

I’m seeing figures of 1 million$ per satellite. Over 10 years that’s roughly 100k/month in mortgage or around 1k customers at 100$/mo.

Isn't this just stack ranking? Hasn't that always been a terrible way to measure quality?

Every car, especially American makes, are drastically improved from even just a few years ago. Being in the bottom half in 2019 is a completely different story from being in the bottom half in 1999, or 1969.
I always feel this way when the car's fuel gauge gets below half.
But they took that cost, haven't they?

PS: besides, who said they don't know the reason?
This is a classic case of American huckster capitalism. Don't ask permission, don't think about the big picture. Barrel ahead and try to corner the market. The goal is to gain profit at any expense.
That's a valid criticism of budget allocation favouring existing modes of conflict. However, things like jamming maximize the technical advantage the US has against adversaries seeking to develop asymmetric threats -- it is possible to make all the (cheaper) missiles miss.

One school of thought is that cyber/IO is like the air force -- it prepares the environment for ground action but doesn't hold territory. So once the West is weakened and divided enough, kinetic operations (Taiwan, Ukraine, Georgia, Syria/Iraq) become possible. So it is still very valuable to have a kinetic defence.

Companies like AHL and Winton have completely different goals and ways of making money... they got into the “quant” (a.k.a. trend following) industry very early and still reap the benefits, they have big AUMs, scalable strategies, etc, but (AFAIK) their actual performance isn’t that amazing (compared to RenTech, Two Sigma, Citadel, ...).

I only interviewed at AHL so I cannot speak of the quality/intelligence of people working there, but judging by the difficulty of the interview, compared to some other companies, my conclusion is that their hiring bar isn’t that high. I also wonder how limited these companies are in their investment strategies - either they cannot invest into more sophisticated strategies (limited by investor agreements), or they don’t want to, because poor known returns are easier to justify (“trend following just had a bad year, nothing we can do about it”) than poor unknown returns (“we tried thes completely new thing that we have no experience in, and it didn’t work and we lost a lot of your money”).
Yeah, that's why I specified individual spacecraft. Presumably the rationale is similar, but it's interesting that this time it's not just a defunct subsystem but rather an entire independent spacecraft.
I took a look at the husband twitter, and I want to correct a big misconception, the credit score we can look at isn't actually the same one the bank used and it can be actually quite different. We actually can't access the credit score they get.

I don't remember the news article, but if really needed, I'll try to find it back. They tried it over 4 individuals, and one of them was much lower than they thought it would be considering what he was saying. They tried to find out why, which is how they learned they weren't the actual ones the bank was using and thus tried to get hold of the actual score. The one from the bank was nearly 200 points better. I don't remember if they tried with the others 3.

I don't believe this was actually her issue, the most simple explanation is that the income they got wasn't high enough... which has nothing to do with her gender.

I agree that credit shouldn't be a black box, that they should be able to say, well your credit score allow you this interest rate, but your income only allow you this credit amount... I know it's a black box to avoid abuse, but that's only security by obscurity.
I agree with most of what you said, however, internal combustion engine is nowhere near as efficient or complete combustion as a jet engine which can get to high 60s with heat recovery. I with somebody had thought of making a series hybrid with a small but optimal turbine based battery charger.

the other benefit is the weight of gas goes down as the flight progresses which is about 1/3 of the total weight so make the design a bit worse but I believe it would still be compensated by cheapness of solar electricity based charging.

on a related note, IMO this is the reason the whole fuel cell shtick from toyota is BS. Because if it were anywhere near economical & scalable then we would be seeing fuel cell powered drones all over.

I run a network of social sites and we've had this functionality for a couple of years, and the thing is people - especially Americans - just don't care.

They love being outraged, even when what they post is clearly labelled as fake they ignore it, and people commenting ignore it.

From the site perspective there's not much more we can do without driving people away, if you try to police content too much people will just go to another site.

But it does get pretty frustrating.

If we want to be all pedantic then certain battery types (metal-air) gain weight as they are depleted.
I’m not familiar with the situation in Canada but here in California we have excessive taxes (counties and municipalities can layer on more tax beyond the state excise tax) and not enough dispensary licenses to meet demand (again, the fault of municipalities more than the state). The legal businesses that do exist are more likely to be run by green field entrepreneurs than people moving away from the black market. That’s what I meant by making the legal market work for everyone.
thats not true, fuel weight is about 1/3 of total plane weight.
There was definitely a huge amount of controversy over this after the first Starlink launch. If I'm remembering correctly, the problems got significantly better after the satellites moved to their final orbits and oriented their solar panels correctly.

Additionally, SpaceX promised to do their best to lower the albedo of this second set of sats, which, based on side-by-side pictures of the two stacks of sats, they seem to have done.

In my opinion, there's definitely reason to be afraid of the effects of Starlink on astronomy, but SpaceX also seems reasonably receptive to making changes in order to lessen the impact.
First, congrats!

The first example of reading a file in sync vs async really makes me feel like you could have a macro of sorts that just lets you write the sync version and have it generate the async version (assuming you only use the stdlib IO based APIs). Usage of threads could even be converted to tasks, etc.

I'm sure it falls apart in various places, but it would really make async (in Rust) a lot more approachable. At which point you have something very similar to how Go does things, which I think is potentially very nice.
> Observing traffic, the flow of materials, following people and finding who meets who.

IANAL, but I’d imagine that then it’s no longer non-public information (at least in the US).
There won't be a humanity who has the need for databases in 50 years.
> Most software work out there is babysitting.

Yes, of a sort. Green fields are rare, and with the way things are today your picking up a massive pile of pre written infrastructure and libraries that you hardly look at (until they are a problem).

The rockstar mentality is not wrong, but some days you need to pick up the pack and walk up the mountain too.

The problem starts at the interview. We give people coding tests to see if they can produce, but that's less than 10% of the technical side of the job. Really we should be giving code reading tests. What does this do, is there anything wrong with it, is there anything you would change and so on.
I think the reason its so hard is when we ask something we are missing out huge bits of information about exactly what we want. Another human knows from experience and context what the person actually wants. When I say I want a webstore for selling keyboards A web dev already has a pretty good idea what I want because they know what a web store does and how it functions and they know how keyboards work so they will know to add search filters for things like switch types even though none of this information was in the original request.

Explaining exactly what we want and covering all of the edge cases is just as hard as using a regular programming language. Until we can have full back and conversation with computers that have a deep understanding of what people want from a program and can ask the user questions like "But what should happen when x happens?".

Could you elaborate on what you mean by that?
They are creating new techniques to tackle people potentially avoiding paying taxes on crytpo. By and large, this is not going to yield a ton of money as its likely small traders, just trading and hoping to avoid paying on what are likely small to no profits. There are obviously going to be exceptions.

They could instead just open up the Panama papers and target people and companies hiding billions. The issue is that this would then target those with money and power something the IRS appears loath to do. So instead the rich continue to pay a far lower proportion of taxes than they actually owe and the poor and middle class get hammered.

The IRS already openly admits to not auditing the rich as its too complicated and to instead going after the less wealthy.

No wonder the rich get richer...
It’s addressed in the autonomy day presentation if I’m not mistaken.
My reasoning will mean little to you if we do not agree on core terms.
Alternatively, a coin-join helps provide anonymity and privacy to legitimate users.

In order for a government to enforce taxation on cryptoassets, they would need to definitively prove that a person owned coins at a specific address. This is basically only possible if coins are bought/sold through an exchange following KYC laws.

I’m skeptical of my assumption but I think this person died not only from the illness schizophrenia but because of the religion that fueled his illness. I theorize psychiatry isn’t wanting to approach religion as bad for some people but there is the possibility of ideology provoking delusions for people with schizophrenia more so than normal people.
I wish I could say that it caused me humor every time I come across this type of justification for the ever-quickening erosion of the concept of personal privacy in the era of big tech. Here's why my gut reaction to interpreting Google's behaviors starts from the core assumption that they are pursing ever-greater levels of privacy-eroding ad tech in nearly everything they do:

0) Google's only purpose is to make money.

1) Google's strongest strategy (by orders of magnitude) for making money is targeted advertising.

2) Google has surpassed the critical size threshold beyond which morality plays no role in business decisions (see surveillance state-supporting tech in China among other issues).

Due to these facts it appears inevitable that Google will seek in all of its large-scale actions to involve ad tech in whatever it produces or engages in. It's how they fulfill their purpose (selling the most sophisticated targeted advertising possible).
Agree with you that the problem is more on language side, I also believe that the problem isn't as bad as it seems with the right tooling.

For example I recently discovered that I can configure PyCharm to a database. Interestingly, after I did just that, the IDE downloaded the database schema and suddenly I got highlighting, autocomplete and refactoring available (well as migrations).

Suddenly I felt like I didn't actually need an ORM.

C# seems to also have thing called LINQ I'm not as familiar with it but my understanding is that it is a language within language that can represent SQL statements. I'm guessing this might be what you're talking. Ultimately I think the solution is that:

- there's a way to efficiently express what data we need (ORM has the issue you mentioned)

- an IDE can understand this syntax so it can help with it the same as with rest of the code.
