> Frankly good type systems displaced TDD for me. They do a better job getting at the goals of TDD than TDD does.

I think it's a false dichotomy. Where you have types, use types. Where you don't, use tests. Either way, get a tool to guide you to the answer and then check the invariant during future changes.

In fact TDD made me more aware of and appreciative of types. Writing types-by-hand is very tedious and wasteful.
I don't think the issue is whether a supersonic jet can be funded, built, and operated. It's whether demand can pay for the resulting costs.

Part of the calculation is that supersonic flight is so energy-intensive that we'd need a major breakthrough in fuel extraction/storage/efficiency. More fuel weighs more, whether stored as a liquid hydrocarbon or as a battery.
They're responsible for common core.
I thought this was going to be about collisions between satellites from two constellations.

As someone loudly lamented a long time ago: please stop using the word “impact” as a substitute for figuring out effect/affect.
Thirded. I would also add Clasp to my projects' list of implementations to run unit tests on[1] if I could easily install it on Ubuntu with a .deb.

Probably most cases you wouldn't even notice. One case is if you make a drawing on keep.google.com
The UI reminds me a bit of a mix between the EoC:IW2 UI (https://gamefabrique.com/games/independence-war-2-edge-of-ch...) and the ingress web UI. The fonts are doing a lot of the leg work for that.

Maybe a bit of EVE Online too.
I wouldn't say it's out of the realm of possibility. Iran-Contra seems like a much bigger issue in terms of the CIA and finding.

I haven't seen any evidence, though, and OP doesn't seem to be forthcoming with any.

What?

I live 100 feet from the urban growth boundary. 20 minutes from downtown Portland. Nearest transit is a quarter mile away and the bus runs once an hour during daylight only. Nobody seems to mind that, houses in this area sell immediately. If you pushed the boundary out another mile it would take no time at all before it would be filled with new homes.
To go even further I think you want to have tests or simulations with specific air resistance as the drag is actually what causes range loss at higher speeds more than anything else. As an example driving 45mph into a strong headwind is also going to be bad for efficiency. I’d actually like to see some tests/simulations that isolate speed (different speeds in a vaccum) and air resistance (constant speed but different air resistance).
The article says they did a test @70mph and the battery lasted 458 miles.
> The problem with this is that it would be putting an obligation on Apple to design and implement APIs it doesn't want to create or support, and implement features it disagrees with.

That's not a problem, it's just life. Pretty much every person and organization has obligations they need to comply with that they may disagree with. For instance, COPPA means Apple (and other internet companies) already need to implement features to keep kids under 13 from creating accounts on their site without parental permission.

> Who gets to decide what APIs and features comply with any such imposed obligation? Who reviews it and certifies compliance? Who decides on how many resources get allocated to it?

Easy: either 1) government authorities or 2) an independent private self-regulatory organization like FINRA.
You have high-stake operations in relatively small code base, so you better pick a language and tools compatible with formal verification or even supporting it natively.
It's not 13% larger. They purport to be making batteries that are more efficient, so they get 13% more power than Tesla's batter pack with a smaller pack.

Here's an article that talks about this some [1].

you can see the difference, but unless you have interest in architecture it won't help you indetifying country, because they could be pretty much in any European country

sure some white buildings next to sea would help me to guess I am somewhere in southern Europe maybe, but I was talking about regular buildings you see somewhere in city center from street, if you take away letters it looks pretty much same everywhere in Europe
Yes, my position is that tests as client don't really tell you the truth about the abstraction because they don't represent a real usage of it.

It is better to write tests for code when you know what it is and what it should do. Tests also introduce a drag on changing strategies- if the choice you made when you wrote them is now not necessarily the optimal one, you must now change your tests or convince yourself that you were actually right the first time.

If people like to work this way then great, I'm just explaining why for me it feels bad and runs counter to my instincts.
IIRC navy subs are capable of parking on the seabed, though they definitely cant reach as deep as the mariana trench.

I was loose w/ words, but I maintain there is inherent compression aspect to Fourier transform, because for a large class of signals, most of the energy is contained in the first few coefficients. See also the similarity between fourier transforms and KL transform for random variables, itself related to PCA.

Ofc, it depends on what you mean exactly by compression. At least for audio, it relates well to keeping the main signal quality because in a sense, the earing system does a frequency decomposition (see e.g. https://www.ncbi.nlm.nih.gov/books/NBK10946/figure/A896/?rep...), and the higher the frequency, the less sensitive to it we tend to be.
> I always wonder if there's a better way to make those types of transitions.

Yes, there is. It's actually pretty simple and takes one step:

1) don't.

I can expand on that though with a few more discrete steps:

1) don't screw over people who already spent time (money) learning your product

2) don't screw over people who paid money (and time) for certifications in your product

3) don't assume that everyone will work better with the new flow

The toolbar ribbons tanked discoverability, readability, and usability.

I'm a bit confused by why they included such high-res images in the PDF in the first place.

Edit: After taking a look at the original I see that they embedded some of the files they created with Photoshop and After Effects directly into the document. They forgot to resize the images, hence the huge object streams in the file.

> efficiency is always great compared to gas

This isn't a given. Money-efficiency in the UK at least is only good if you charge at home. If you pay on-street prices for electricity, you can easily spending more per mile than a gas car.

Eg. An electric car might do 330 Wh/mile. A recharge on the road would cost £3 (connection fee) + £0.30 per kWh. That means if you top up 25 kWh, you'll end up paying £10.50, and able to travel 76 miles, or £0.138 per mile. A typical 2018 gas car gets 50.8 imperial mpg costing £0.108 per mile at todays gas prices in London.

Overall, unless you can charge at home, an electric car will cost you more per mile for fuel/electricity alone.
Agree. It’s an ok way to convey an intuitive feel for the distance, but as the expression goes ymmv. In real road tripping, what matters is having a fantastic charger network with redundancy on major routes and good coverage on minor routes.
The economics of application vs library programmers is a managerial decision.

Any application project that starts writing library-style code will slow down, and possibly gain the scrutiny of the managers / executives. In "Large Scale C++", Lakos notes the importance of manager-level buy in. You must have a library-team, with a separate stream of money, if you expect to be sustainable.

Application-style programmers trying to make a library on their own will lose the economic game.

--------

"Who pays for the library??". Well, if your organization has 10 teams, all using a specific library (or that could benefit from a hypothetical library), its actually a very difficult question. This is where hierarchy and management must step in to solve the issue. No sane manager wants to spend their own money helping other teams with no recognition!

Trying to write a library without solving the long-term economic and managerial issues is suicide. You'll only slow down your own application and make your own project look weaker compared to your peers (at least in the short term. In the long term, the library code will blossom and make your team more productive. But surviving the short term is a major concern in reality)

I imagine it would turn out similar to the game store market on PC. You'd have the various large publishers all having their own stores to get their games/software. Personally, I much prefer to just buy and manage all of my games through Steam... but I do have a handful of games through other launchers. It's annoying, but it would be weird to not allow them to control how they deploy their software.
Read books. See what works for you.
The firs thing is to decide acquisition method. Inbound or outbound?

Inbound is great if you are well known inthe space. Else it's slow.
If you don't have a large network reach out to people.

Find the right channels that would work for you. Read https://brianbalfour.com/ he has a page for learning to be customer acquisition expert. Lots of good recommendations.

Most companies survive on a single channel. So you must find which one is that for you.

If your only way to reach prospects is ads, you must have a good price on your product . High LTV to support CAC.

If your users are active on LinkedIn. Then try apps like clickedIn.

If your prospects read emails (e.g. marketing, swe ) then try cold outreach. Read more on lemlist.com

Join Facebook groups where SAAS founders hang out. You might find more tricks.

If you dont have sales experience then focus on product led growth. Read the book.

Regardless of sales, you must have good grasp of marketing even if you intend to drive product led growth.

Good luck.
If I’m right, turbine jet engines won’t hold up against supersonic airflow anyway, so intakes has to be cleverly designed so as to feed them with subsonic air of sufficient volume at all speeds. So there might be some wiggle room between engines with sufficient TWR and durability?
It's not brainwashing. Signaling is a big part of life. We like to pretend that humans are rational machines, but in reality people spend most of their time doing irrational things because they are rewardding, like, i don't know , arguing with strangers on the net for self-importance reasons. Apple's customers are easy to mock sometimes because they make their signaling slightly more visible by paying extra for it, but the vast majority of ppl would act the same under the same circumstances.

So now the US government and the EU will be making legislation that specifies phone APIs and designs user interfaces. Great!

Not going to happen. Apple will simple close up the App Store into a private premium feature delivery system. Meanwhile the entire rest of the industry will be stuck with a new version of WAP. Thanks guys.
1. Physicians in the US don't have a union. Some conservatives call the AMA a physicians' union, and while it shares some union functions it simply is not one. Physicians are licensed to practice by individual states.

2. Physicians are responsible for writing prescriptions, pharmacists dispense them, and patients self-administer in most cases. The opioid epidemic was caused by failures at each of these levels, not just when writing the rx.

3. Physicians are routinely prosecuted, lose their licenses, and go to jail for this: https://www.deadiversion.usdoj.gov/crim_admin_actions/index....

Your lack of information on the topic is not the same as a systemic problem. Please do a bit more due diligence before making claims like this.
It makes perfect sense when you realise that law enforcement's historical and primary goal, over and above protection of us, is the protection of capital.
How much "development" did it take? Oxy was first manufactured in 1917. "Opioids relieve pain and are much sought by opioid users", film at eleven. Any physician who didn't know what would obviously happen when this drug was prescribed is one whose care I would avoid.

But yeah, take all their money. The actions described in TFA obliterate the corporate veil. Frankly I don't know how they've avoided assassination attempts by the families of addicts.
Photon – a live demo of a natural language interface to databases
Sources for this claim, in case someone doesn't believe the op here. Official requests to move/dispose/sell the nitrate were made 6 times over 6 years [1] [2].

Blaming the company that owned the ship is does nothing but shift responsibility from those responsible for storing 2400 tons of explosives near a residential area. There will always be reasons why the government chooses to seize cargo, taking over 6 years to move dangerous cargo, and storing it in shoddy conditions, is on the government. Perhaps if this had happened shortly after seizing the cargo the company could be more accurately blamed.

Everything you need to know regarding the recent Experian Data Breach
Research revealed that passengers thought that the fare was higher than it actually was, so the airline raised ticket prices to match these perceptions. It is reported that British Airways then ran Concorde at a profit.

https://en.wikipedia.org/wiki/Concorde

"Laws" that can be broken hardly seem to qualify as "laws of physics".

An increase in maintenance costs due to the planes being very old and out of production also doesn't qualify:

British Airways and Air France were able to operate Concorde at a profit, in spite of very high maintenance costs, because the aircraft was able to sustain a high ticket price.

Its estimated operating costs were $3,800 per block hour in 1972, compared to actual 1971 operating costs of $1,835 for a 707 and $3,500 for a 747; for a 3,050 nmi London–New York sector, a 707 cost $13,750 or 3.04c per seat/nmi, a 747 $26,200 or 2.4c per seat/nmi and the Concorde $14,250 or 4.5c per seat/nmi.

So 50% more expensive per seat/mile than a 707 and twice as expensive as a 747.

I once fixed a bug like that, then went wait a minute. Sure enough source control revealed I'd made exactly the same fix 2 years ago, and 2 years before that someone else had done exactly the same. In the odd years someone else undid that fix to fix a different bug that seemed unrelated. Once I figured out what the other problem was I was able to find the more complex fix for both situations.

I wished I had heard of automated tests then
In Nonviolent Communication by Marshal Rosenberg (nice summary: https://medium.com/s/please-advise/the-essential-guide-to-di...), instilling guilt (and shame) is considered to be a violent way of communicating. First, I had a problem with this definition of violence. Then I saw it fits the framework of violence: "either you do as we say, or we will intentionally make you suffer".

I say "we" because, in many cases, it is not a single individual but a community or any social group.

Jewish and Catholic cultures are famous for their guilt-driven development approach to upbringing:

Scoundreller's observation it does seem that there are a number of systemic issues working together in the US to create this problem. And one of these seems to be how doctors prescribe medication.
In theory, the SEC could decide to count those. In practice, that's basically unthinkable.
The sheer storage capacity of the battery is less interesting than the cost. Getting below $100/KWh will reduce EV price to FAR below ICE vehicles; while BEV's are already at parity with ICE on total cost of ownership, BEV's are going to continue the long descent to MUCH cheaper, and $100 is going to be an important milestone.

I think new ICE vehicles are going to be banned in most major economies by 2030, so really, ICE is having its last decade of relevance in new vehicles. Given vehicle replacement cycle is around ~20 years, by 2050 the ICE vehicle stock will be reduced to 99% specialty machines like classic cars, motorcycles, and various heavy equipment for industry.
But note, this is just the small almost single-person sized prototype that's planned to fly. It is a huge leap to get to the next step, the commercial transport sized plane...

No rational person could think it looked like that, and this would still not be an acceptable response.
Sure, negation and deletion are non-monotonic. And sure, they require coordination and waiting if you really want serializability. But the modern default is snapshot isolation, and experience has shown that there are many many applications that are quite willing to live with this weaker level of isolation (eventual consistency). You can get monotonic reads/writes, without having to wait for all of them to respond, which is the point of this paper. Multi-version databases are lattices.
You need to understand what you are buying. If you buy an Apple product, you can use it in certain ways. If you buy a Dell or some other product, you can use it in perhaps different ways.

It just doesn't make sense that we are trying to force Apple to allow us to do things with their products that they do not support.
U.S. 5G Speeds Slump as Global Speeds Rise
So these are 'smart' people who somehow can't meet the relatively low traditional income requirements ($200k/yr) but who are now assumed to be financially sophisticated enough to take on the risk of these securities without the protection provided by normal regulatory disclosure filings. This strikes me as insanely stupid akin to the ownership society nonsense which precipitated the housing crisis.

VC follows a power law and the vast majority of these investments will fail.
Didn't realize. Pacific crossings seem like the ideal place to capitalize on high speed, and it seems silly not to make that the primary and expand from there.

Yes, technically, "everything a company does is revenue-related". However, you can realistically draw a line sonewhere between blocking illegal material (pirated/malware) and blocking apps that don't pay Apple their 30%. My comment was not intended to be the exact legalese that would be required for such a limitation, but you can probably gather roughly where I draw the line from it.
The US has a much higher homicide rate than its peers, which almost certainly means police face more dangerous situations in the US than in those other countries.

I think this distinction is harmful. Your application code should include areas that function as "library code." We do this at work with an explicit UI library that we package separately, but there's no reason it needs to be packaged separately, just create directories that represent some library-esque element of your application and heavily test it and write docs for it, like you would a library.
The reality is always far worse.

A brand new Model 3 will do 310 miles of range. Only you're not supposed to use the top 10% or bottom 10% unless you absolutely have to, to avoid damaging the battery. So now it's 248 miles of range. Unless it's extremely cold or hot, or you have a heavy foot, or you have a roof rack, or it's uphill... Where 200 miles might be more accurate.

My 18-month old Model 3 will do 301 miles, which means best-case 240 miles reality unless I want to damage the pack (more).

I actually love my Tesla, and the pack degradation is fine, and there are lots of other benefits....

But when someone says "500 miles range" I'm going to read that as "probably ~350 miles real range after a year of ownership and if it's cold or something".
Interesting. I haven't touched BIND for years and am out of the loop, plus memory is fallible anyway. Just looked at it and have ended up at RFC 8499 from January 2019: https://tools.ietf.org/html/rfc8499

Master server: See "Primary server".

Primary server: "Any authoritative server configured to be the
source of zone transfer for one or more [secondary] servers."
(Quoted from [RFC1996], Section 2.1) Or, more specifically,
[RFC2136] calls it "an authoritative server configured to be the
source of AXFR or IXFR data for one or more [secondary] servers".
Primary servers are also discussed in [RFC1034]. Although early
DNS RFCs such as [RFC1996] referred to this as a "master", the
current common usage has shifted to "primary".

So it seems `primary` is essentially the official term in DNS, but `master` may well be the preferred term by BIND itself.
