Neat. Does it somehow know which barcodes belong to your packages, or could a thief rip a barcode off any package and use it to unlock it?
I actually thought given the size of the position, he was part of the group manipulating transactions in order to liquidate at the top. Holding those positions long term doesn't seem smart.
>They aren't just playing golf in their office.

A lot of them are doing just that too (playing golf and delegating most of the work), all across the globe, in very rich positions.

But that's a red herring. Even the other stuff, meetings, negotiations, decisions, etc, are part of what they do by choice, not as work in the way billions of people do work.

Unless you'll go hungry or homeless if you've stopped working, you're not working, you're just doing what you want to do in the way you want to do it.
I also hear arb is doing fine.

I wonder how it works though. Most exchange APIs are terrible and it is simply not technically feasible to do anything using those APIs.

Also prices at too many exchanges move in absolute lockstep.

Must be private, privileged access to better (internal) APIs, profit sharing, rip the face of "retail" investor kind of deals.

After all the "exchanges" are not really exchanges as we know them in other markets. They're more like forex trading.

I think the crypto market would benefit from a (semi-)regulated impartial exchange where other firms can become members and act as brokers to direct retail flow.

But unless there's some sort of regulation about it it would just be a private business that could kick out any member for any reason. To much risk for the members.
What do you eat at a restaurant that costs that much?
I don't think i can release the exact code but my case was like this.

I was writing a little program to help glue some things together in our build/release pipeline. This tool would be deployed to the build server and get invoked by the build agent. (This could have been a script, but the complexity got to be too much to keep organized)

The tool had two halfs:

- The frontend whose job was to gather up all the 'input' from CommandLine and Env vars, do some parsing, then spit out proper types/objects.

- The backend that would interpret this data and make decisions, make some API calls and maybe copy some files.

Because of the way our our software is built, we have 5 or 6 different 'flavors' of our app that needed special treatment during build. The complexity of branching on if it was a build step or a release step, the different flavors of our app and the need to deal with input data that may or may not be there got the best of me and I spent weeks making tweaks to deal with NREs at runtime because i hadn't handled some weird case.

So i trashed the tool and rebuild the front end in F#. I spent a little time making a very accurate type representation of the data model. Including defining a lot of stuff as optional and introducing a lot of discriminated unions to represent possible branches. Then i essentially just filled in the blanks (match cases) and fixed the compile errors until every case was covered and I was done. No bugs.

You see the big, big win of F# is the default path doesn't let your cheat yourself.

You MUST handle every switch/match case.

You MUST fully construct your records.

If your function may fail, you MUST use Option to express None/Null

And you MUST handle every option type as potentially None and write handling logic

When you define your data model, just be on honest about what data needs to be where and the compiler will keep you on the straight and narrow.
I don't know if a re-usable Electron will ever make sense, but it's an interesting engineering problem to think about.

As lithium-ion batteries improve the potential mass fraction for each Electron stage gets better: lighter batteries mean more propellant. In a decade (maybe sooner) it might become feasible for the first stage to retain enough propellant for a propulsive landing like the Falcon 9. And in this case I think there's a big pay-off with the electric pumps: there's no need for a hoverslam, since the engines should be able to deep throttle to an extreme degree that's not practical with conventional rocket engines.

In a shorter time-frame the Electron first stage, because it is so small, is probably air-recoverable using the same approach that ULA is considering for recovering Vulcan engines.
Common Lisp is not just "a lisp". I can probably count on the fingers of one hand the number of Common Lisp compilers I've seen in my life. I can write "a lisp" in a couple dozen lines of code, but my copy of CLTL2 on the shelf is about 2 inches thick.

I'm not saying GPU offload is easy. As you point out, no general-purpose language today does that (and LLVM doesn't seem to offer it as a feature), so you'd have to implement that either way. The choice is "new compiler + GPU target" versus "mature portable compiler + GPU target". Why is the latter "not realistic"?

I find it hard to believe that the architecture of every (free) compiler is so horribly suited to this that we need to start from scratch. We've forked CL compilers many times, for new architectures, but I've never seen any architecture that required starting over.
Credit Repair
Happy Tuesday Friends Alex from New York, I sincerely thank Mr. Cole for putting he’s all in making my credit good again I’m very grateful. I had a low score 520 bankruptcy; Eviction and tax liens to dispute which did not allow me apply for a mortgage loan couple week’s back. I sorted for a solution online where most of the credit blog I came across got Mr. Cole talking about him and how he has helped a lot of people fighting with credit repair and fico score issue fixed in short while. I contacted Mr. Cole for a Credit repair service and explained everything to him and how soon could he get the repair done. It took awhile before he replied me and then he asked me a few questions and told me to forward my info details for the job which I did and after 5 days he delivered on my credit increasing my score to a High 800 also increasing my credit limits and leverage awesome isn’t. To contact Cole email COLEFRANKSERVICES@GMAIL.COM phone +1 (972) 798 8812 have Sound Christmas.
Price starts at $1/hr billed in 1 second increments. Frequently we charge less than that, since the price is dropped with volume, and that's typically businesses have a steady amount running through them (a few thousands hours). Medium usage scale would be $0.25-0.75/hr (e.g. 10,000 hours to 100,000 hours a month scale). Large usage is around 10,000 hrs+ per day and the price can be much lower per transcribed hour (like $0.15/hr).

That's the ballpark for cloud + batch mode. If it's cloud + realtime it's a little more. If you need it on premise it's a little more (we work with integration partners to do parts of it).

Pricing for speech is interesting since there's more than just how many $/hr in the equation. Usually businesses care about turnaround time, throughput, failover/availability, and a collection of features. So we usually want to talk about those goals and price accordingly to support 'em. I definitely wish I had a better way to frame it than "it's complicated"!
I would say it's the same with Rust and Haskell. And I agree, the superior type system of these languages is really a game changer for me and it's very hard to go back to languages missing these features.
> Java primitives (short, float, double, etc...) are copied to the calling function, but arrays and objects are passed by reference.

Not really. "Pass by reference" is a specific term for a much different technique which is very rarely encountered these days. It means that if you pass a variable "foo" to a function, that function can assign "foo" to some other value and the value of "foo" will also be changed outside of that function.

The confusion, I think, is that true pass by reference is almost never encountered in modern programming languages and courses, and some people mistakenly use the term "pass by reference" when explaining the difference between e.g. primitive types and objects in Java.

Java passes everything by value. The value of a variable assigned to an object is indeed a "reference" to that object in memory, but that's a coincidental use of the term "reference."
If you work with any kind of evolutionary system or neural networks or meta-optimizers (Like Schmidhuber's Gödel machine) there comes a point when you realize that "intelligence", whatever it is, should be expected to arise. Evolution and meta-evolution proceed at the same time in life, so intelligence should be ambient in Nature. (This is what Wolfram has been talking about with his "New Kind of Science" tome, etc. Gregory Bateson also talked about this in "Steps to an Ecology of Mind: Collected Essays in Anthropology, Psychiatry, Evolution, and Epistemology" and "Mind and Nature: A Necessary Unity (Advances in Systems Theory, Complexity, and the Human Sciences)".)

Now, combine this idea, that meta-evolutionary adaptation naturally leads to ambient intelligence (put another way, living systems have as much intelligence as is adaptive, the limiting factor on the intelligence of the global ecosystem is NOT the difficulty of being intelligent because it's actually really easy to be intelligent) with the recent discovery that the oceans are a sort of naturally occuring Grey Goo[1], and it seems that the oceans themselves are intelligent.

And late 19th and early 20th century urban utopias were the result?

There are certainly problems with car culture (especially environmental impacts), but the idea that pre-car common patterns of urbanization were “good urbanism” is something which needs some support.

Because then they would have only 2 or 3 hours to deliver all their packages? (I'm assuming most people would want to get their packages between 8pm and 10pm)?
I recently subscribed to a different box service, which does all the food prep work for you (chopping/dicing/slicing, making sauces). It generally takes us 20-30 minutes less to prep, cook and clean over Blue Apron. IMO this is the main value prop Blue Apron is missing.

For me, Blue Apron is really only solving for time spent looking up a recipe. In most cases, I'm already going to the grocery store each week. So, where's the value in spending $80/week? If you can shave off the time I spend in the kitchen, that's what I want to pay for. I suspect most people subscribe, love the new recipes they would typically pass over from the internet. And then a month in realize "I'm not saving any time by doing this... I don't want to spend an hour or more in the kitchen tonight... Let's just get take out.".

Aside from that, Blue Apron's fulfillment execution is very wonky. Missing/Bad/Broken ingredients, late boxes (which spoil if not delivered timely), and excessive packing.
I enjoy when in discussions like this the person saying the things can’t simulate each other proceed to prove their point by writing two computer programs and running them on the same physical machine...
It's like we're completely ignoring the role that CA's clean car requirements and incentivies have had on the EV market, including making it possible for Tesla to exist in the first place, and for financially keeping Tesla afloat for the many years of failed execution under Elon's leadership.

SpaceX owes its success to Gwynne Shotwell, not Elon Musk. It's her ability to execute that has SpaceX on top.

AI has been a thing for decades. But it's cool to see Elon Musk take credit for yet another thing he didn't actually do.
Isn't deep nesting (hence deep indentation) a sign of code smell? Yeah, you might end up shuffling the logic into a new file or a function that makes the file much longer, but I've noticed when doing that kind of refactoring it forces you to clean up the scoping quite a bit so there's less state to keep track of.
How to Take Advantage of One-Handed Typing (The Best Ways)
>Disintermediation did happen. I can reach my fans directly. Many independent shops have their own website. But disintermediation doesn’t mean guaranteed customers, just that the independent shop owner doesn’t have to pay $1000 in rent every month to sell.

What we wanted to see was people buying 90% of the time from smaller shops, directly from producer websites, direct artists sites, and so on.

Instead, the intermediation is just what happens the 10% of the time, which is probably even worse than what happened pre-internet (when e.g. music fans in England would get most of their music from indies, not from Spotify and co).
I joined the Newton team in 1988 as an intern (and stayed for 8 years). It's interesting to hear with 30 more years of perspective JLG's story of the Steve Sakoman situation that resulted in that team's existence. At the time I had no inkling of the drama that must have occurred that resulted in the creation of a totally isolated team in that totally isolated building on Bubb Road. I did realize how lucky I was to be working there, though. :)

Or, we could have all social networks legally mandated to care about discrimination using the power of law and punitive fines. There's no reason to let the existing ones carry on as is.

Historically black colleges were an alternative to colleges that discriminated, but that didn't make them a solution for discrimination in education.

We have a few of those in LA. They're called My Fit Foods and other similar names. They prep the food that day and offer breakfast, lunch, and deener options. Each meal runs 8 - 12 bucks. They're pretty wholesome usually, but they have a decent selection.

My fit foods went bankrupt not too long ago, but most have been transformed to local versions of the same company.
There is an elegant universal notation for integers, called "variable-width integers" or "varints" or "bigints" or similar. It is reviled amongst many, and doesn't see much use.

There is an elegant universal notation for rationals, called "quote notation" or "finite continued fractions" or "p-adic rationals". It is largely unknown and sees next-to-no use.

There is an elegant universal notation for computable reals, called "computability". We use this all the time, but almost never for computing reals.

Floating-point numbers are fussy and require careful management in order to avoid buggy algorithms. In contrast, there exists an algorithm (although it's an open problem to express it in a quick way!) for taking the fifth root of any generalized continued fraction or any Turing-computable real, in a way that allows the result to be used in further computation. Somebody should tackle the Gaussian distributions next!

Appealing to people who "want to cook", but doing so by turning yourself into a production-line assembler.
Like saying your want to learn carpentry, by buying some Ikea flat-pack.

What confused me (and makes me think I've overlooked something) is why nothing more interesting has come along from the supermarkets. In the UK at least, they're all online and deliver - but they all seem to stick to "buy your ingredients and we'll deliver them".
I'd quite enjoy one that let you browse recipes and would stick all the ingredients in your basket - but then added some intelligence.
e.g. You add the "roast chicken weekend meal" to your cart, and it asks "are you going to eat all that chicken?"
For £5 extra would you like to add some bacon, creme-fraiche, tarragon, frozen-pastry & peas to enable you to make a lovely pie on Monday?
Or asks "what's in your fridge" - here are some recipes and prices for things to use it up?
Could even add some intelligence - I don't like mushrooms, so when recommending a chicken pie and providing a recipe, switches something else into my basket & recipe (leeks are lovely).
Or would further adjust the recipe - you said you needed to feed 8 at the weekend, so I picked the larger lump of meat, and have adjusted the cooking time in the recipe.
Or "Do you own a pressure cooker, a freezer and have 2 hours free this weekend to batch cook some chilli"
Or... basically Blue Apron and the rest seem to be trying to solve a real problem, completely the wrong way.
It's possible to deploy Jenkins "right", but good grief is that rare. The typical Jenkins deployment feels like every new project or pipeline demands a new plugin, and will harass the ever loving piss out of you to upgrade if any of those plugins get a bit stale.

Why run a command in a shell build step when you can install a plugin that abstracts everything away in a non-intuitive manner?
Symbolic manipulation is undecidable, hence programmers prefer numeric approaches. But, symbolic approaches are clearly superior if the programmer does them a priori.

(FYI your https://deepgram.com/v2/docs links are giving "error": "Not Found" JSON responses.)

I love progress in this space. Something I also think is necessary, though, is innovation in the discoverability interfaces around speech data. Can you search over potential transcriptions weighted by their likelihood, rather than just doing full-text search on the most-likely transcriptions? Can you visualize multiple potential transcriptions inline without overloading someone's visual cortex with information? Can you one-click-to-listen to any specific line? Can you enable people to switch conversations on the fly to an "off-the-record" mode, with such confidence that the default can be that every conversation is highlighted? Can you do all of this from Slack? Can you make setup a one-click process with Twilio OAuth? Can you do all of this from a web app that requires no coding?

All this, I'm sure, is part of an ecosystem that will be built on tools like yours, and that ecosystem fundamentally depends on the quality of the data - so it makes sense for you all to focus there first. But to the extent you want to capture the entire "stack," there's a tremendous space for someone to take the level of "passion" for data quality and apply that same instinct to quality-of-experience.
People said the same about Iridium. It's entirely possible that Starlink could work as advertised but not have subscribers to deliver that level of profitability.
I thought about doing some subscription cooking service before but I recently joined the New York Times free 6 month trial and I didn't know/expect how useful their recipe section is. Takes most of the anxiety of choosing what to cook. For those who know how to cook, I highly recommend trying it out and following their weekly/daily suggestions. With this and the grocery delivery services, it doesn't make financial sense to join subscription food services. Though admittedly, I was taught how to cook at a young age so it's easier for me to follow the recipes.

> Most software in your local Linux distro's repository is maintained by a "community" that might just be one person working in their spare time.

There is one big difference between Pypi and a distribution repository:

With Pypi, every contributors are truly individuals, they upload their packages alone, they maintain them alone, they basically do whatever they want. The maintainer here can likely be a single point of failure.

With distribution even if most packages are maintained by a single person, the repository content is the responsibility of the distribution as a whole. These distributions have formalized their processes and policies a long time ago. For example, if a critical security issue is found, unless something goes wrong, the package will not be left unpatched, even if the package maintainer is not reacting.

Also, Distributions put huge efforts into providing stable versions, if you are using packages from a distribution, you have some guaranties about stable APIs, and that these packages with stable APIs will actually be maintained for a few years. Even if it's not always perfect, with non-critical bugs not always fixed, it's a far cry from Pypi where the only true possibility is to hard pin every single version of your dependency tree inside requirements.txt.
A third space can never align with another line since it will be an odd number of characters while indents are always even (or vice versa). If you are two chars off, well at some point you need to be responsible for your broken blocks.

I agree with the other person that says this doesn't really happen in the real world with a baseline developer and editor.
