That's interesting, what industries do your clients work in?
Another point to consider: many all-water routes are currently planned with excursions to allow picking up cheap bunker oil en route. Remove fueling concerns and you can run more direct routes.

UNWIND-PROTECT is a building block.

Resource management in the MIT Lisp OS ca. 1980, approximate example.

One would define a resource of arrays, where arrays can be allocated and deallocated. They will be managed via a pool.

(defresource 2d-array (rows columns)
:constructor (make-array (list rows columns)))

Now user code would use the USING-RESOURCE macro, where it spans a dynamic scope. Entering the scope allocates the resource. Inside the scope the resource is allocated. Leaving the scope will automatically deallocate the resource and put it back into the pool. A deinitializer may free memory as needed.

(using-resource (my-array 2d-array 100 100) ; get me a 100x100 array from a pool
(setf (aref my-array 42 42) 'the-answer) ; setting the array
(print (aref my-array 42 42))) ; reading the array

To make sure that the resource gets deallocated, the above macro form will expand to something using UNWIND-PROTECT:

...
(unwind-protect

(progn ; protected form
(setf my-array (allocate-resource '2d-array 100 100)) ; allocate the array
(setf (aref my-array 42 42) 'the-answer) ; setting the array
(print (aref my-array 42 42))) ; reading the array

(when my-array ; exit form
(deallocate-resource '2d-array my-array))) ; deallocate the array
...

This is an example of manual memory management using a pool of resources, where the DEALLOCATE is done always via UNWIND-PROTECT.

Thus the user will not explicitly use UNWIND-PROTECT, but some macros which use it in their expansion...
Renewable methanol (ultimately via atmospheric CO2 + hydrogen from water) looks a lot more plausible as the long-term option, and is being deployed already. Much cheaper and no unusual risk profile, see Maersk and JP Morgan:

https://www.fastcompany.com/90923816/maersk-first-cargo-ship...

https://www.offshore-energy.biz/jp-morgan-confirms-deal-for-...

> "The utilization of green methanol on vessels is capable of eradicating SOx and Particulate Matter (PM) pollutants, while delivering a 60% reduction in NOx emissions. Furthermore, when measured on a tank-to-wake basis, it achieves nearly 100% reduction in CO2 emissions when compared to conventional marine fuels."

As far as nuclear, I can't imagine many port operators are going to take the risk of irradiating the entire port for decades due to a catastrophic accident or deliberate attack that lightly. Countries might be more willing to accept stationary floating nuclear power plants as they'd have tighter control over them (although putting a floating nuclear power plant in SF Bay or similar locations also seems unlikely).
It’s a well written fable. There’s a pretty well narrated animation of the fable as well [0].

Well, look at the other side: Incognito was born because Google does not allow you to turn off browser history in Chrome whatsoever.
I understand that, and LocalSend looks great for what it does. But AirDrop is so insanely useful to many of us because it allows us to share a large file with a person, regardless of whether we are on the same network or whether there is a network at all. If you need that and you can't, it's quite frustrating.

The original post was about being an AirDrop alternative, which it really wasn't.
You’re suggesting powering large tankers using PV cells? I think it’s less about cost and more that there’s insufficient power density to power a tanker. Hydrogen fuel is probably the only way to do that and you’d probably need a nuclear plant close to ports generating it on demand because hydrogen is energy intensive to create and supremely difficult to store (+ storage would still be a problem on ships and massive explosions would be a real risk)
None of that is necessary because you are not exposing anything to the internet. We are still talking about local sharing. Android does not have a firewall so there really is nothing to configure. But if you think it cannot be possible, try it for yourself.
The vast majority of missionary work these days is virtue signaling disguised as a grift.
Some things are better universally. That bad part is proprietary. It would be best if it was universal and open.
Yes, in loads of shops. See trunk based development.

IIRC as a result of Ingenuity's success, one of the proposals for the Mars sample return mission architecture involved several helicopters to retrieve Perseverance's sample canisters (it drops them as it goes along, so that there's no worry about how to get the samples out of the rover in the future).

I should add though that the prospects of the parasites in Congress properly funding such a complex mission seem pretty low for now.
This is silly.

If we ever get the capability to manufacture thousands of SMRs, then we are better off placing them on land, with the resulting decrease in emissions coming from land-based sources. A ton of CO2 is a ton of CO2. If we ever get to eliminate all the land based emissions, then we are well into net negative territory.
Does it need to be financially viable if you’ve got the military budget at your disposal?
I came here to recommend this book as the title of this article mirrors its title's key descriptor.

It's one of my favorite books; throughout my time reading it I would periodically put it down and just sit with awe in imagining the science and the work happening there throughout the years depicted.

I need to sit down and read it again; but I'm afraid to, as in a way it just gives me this odd sense of mixed unfounded nostalgia and jealousy and a bit of dread for not being a part of something similar anymore.
I'm using C++ to build jank, a native Clojure dialect on LLVM with C++ interop. All of Clojure's runtime objects are dynamically allocated and the churn of reference counting is far too slow, compared to garbage collection. I had originally started with an intrusive_ptr and atomic count and the Boehm GC was about 2x faster for that benchmark (and at least as much for every later benchmark).

Even outside of writing languages on top of C++, if you're using something like immer, for persistent immutable data structures in C++ (as jank does), it has memory policies for reference counting or garbage collection. This is because immutable data generally results in more garbage, even when transients are used for the most pathological cases. That garbage is the trade off for knowing your values will never be mutated in place. The huge win of that is complete thread safety for reading those values, as well as complete trust on reproducibility/purity and trivial memoization.
Show HN: Learning Rust for C++ Programmers
This is a collection of YouTube videos I made which target C++ programmers who want to learn Rust. Each video is accompanied by a web page with all code and commands, such that you can try out everything yourself easily using copy/paste and play with Rust in this way.
This is the only real takeaway of the article. “I don’t like this because it’s new to me, therefore it’s universally bad.”

I live in Boston and there was a similar freakout about the gas lamps in Beacon Hill being replaced by LEDs. Not a single person I talked to about it knew that the gas lamps were only added to the neighborhood in the late 70s to make it look more quaint and historic.
If you can torrent there is no point to YIFI - the catalog of available torrents has everything they have and more.

That aside though, there are still plenty of good titles. More than ever. People just have no clue where to look or want more of the stuff they liked 20 years ago I guess.
While I agree that modern societies and especially global wealth are very inequitable I think medicine is one of the areas where it is almost universally agreed in practice to raise all boats. Generic medications are made available, foreign aid is often in the form of medicines and medical support, and global institutions are funded with the aim of raising all boats. Should life extension become possible through medicine or treatments it seems likely that the existing process of trying to achieve global medical equity will continue. Clearly life extension will be very highly valued and if it is out of reach of 95% or 99% of the human population there will be intense pressure to socialize its benefits to everyone. Where I can see problems is if life extension is out of reach of 50% or 75% of the world population due to material/equipment/personnel costs; that's a lot harder to socialize globally and would be similar to advanced cancer treatments and organ transplants/replacements which could be seen as the leading edge of longevity treatments.

I don't think there's a moral argument against expensive cancer/organ treatments being made available in wealthy countries; it doesn't seem like any progress on treating those diseases will be made at all if the treatments can't be made available, regardless of their extreme inequity.
Trust me, the moment I started taking shoes seriously, large swaths of men (of all ages) started giving me compliments for my Jordans (and I'm talking about black friday deals from nike, not the custom bidding war stuff)

I mostly started doing this because I noticed that at least when on sale, Jordans/Air shoes seem to be both economical and of elevated durability and quality compared to traditional running shoes. I also like high-tops and find the comfort and support that they give my ankle to be nice.

That said, I do live in Nike's back yard and that may have something to do with the seeming obsession I've seen among men for sneakers.

re: all the other people claiming it's entirely "status" - where is the status of shoes who normally retail for ~100-150$ USD when not on sale? That's like two levels above bottom of the barrel. I claim there are other reasons for the success and admiration of those shoes.

In all honesty you sounded imperious about it so I thought you were the young 'un :-)

Probably mistakenly based on my own idea that any kind of idealism tends to be lent to younger people and gets balanced over time.

But re-reading your post, I shouldn't leap to conclusions.
The Russians have also left broken nuclear reactors at the bottom of the sea, because they don't care about the environment very much.
When someone mentions the "disneyfication" of Times Square I'm declined to think they have either very selective memories or they were never around that area and 42nd Street in the 80s especially late at night. They can still hang out at the Port Authority if they want to experience echoes of that time.
You see someone you admire wear them, so you want them because they become a part of an aesthetic / community that you admire and want to associate with. Then from there you might get drawn in to rarer, more expensive versions to signal a higher standing in that community.

We all do it. We’ve all bought in to something because someone we admire has it / does it, without evaluating from first principles.
A lot of critical responses here are saying "this distracts from getting people to do the right thing". I'm open to that, but what is the plan for forcing organizations that are doing the wrong thing to do the right thing? We're talking about businesses that mismanage the sensitive data of millions of people. "They should be doing things right" doesn't seem like an adequate response to this situation.
Am I the only one that thinks it's not a good idea? I mean the signal hasnt traveled very far, but yeah these announcements "hey, we're here" aren't very nice.
SwiftUI and all the other Apple frameworks that allow you to do more than read and write text to a console don't work on Windows. Beginners should just use an IDE. If one isn't available for their language/platform, that's a sign of things to come

You don’t need to implement airdrop as separate functionality.

If you are capable of sharing a resource in a message or album, it is also automatically shareable via airdrop. iOS treats them all the same via the share sheet.

>The US could have simply vetoed the resolution if it was considered a threat.

I'm not advocating the theory, but W. Bush wasn't inaugurated until early 2001, so if it was a difference between admins it couldn't have been vetoed in time.
This is good advice to surface the way we work, but I don’t see why you would push to main for Ship rather than raising a PR that you merge immediately (Show), if you’re using PRs anyway.
The AirBnB/house flip aesthetic is truly quite lowest common denominator.
Risingwave is also a really strong competitor in the same space as Materialize.
At least when I used to work at Apple ~4 years ago, our internal clouds were nowhere near the robustness needed to open up to the public. Poor security/isolation controls, outages, clunky usage, etc.

Apple's cloud software engineering muscle is fairly weak and providing an IaaS might be "easy" for the hardware side of the company, but very difficult for the software side.
Not entirely sure about Obj-C version.

Disagree regarding frameworks, though. The newer snapshot-based APIs for NSTableView, NSOutlineView, and NSCollectionView (added in 2020 as part of macOS 11) are a massive improvement over the old index-based ones for example, and there’s been numerous polish and quality of life improvements scattered throughout.

Also disagree about Swift if only for the large number of things it comes with out of the box that’d require a third party dependency with Objective-C, but so many more errors being caught at compile time, no need to maintain header files, and no awkward split between C and Obj-C for basic types are nice too. I still enjoy Obj-C for some types of projects but as project complexity increases so too does my preference towards Swift.
You wish to send it to another apple device.
Does this actually happen? Or is it just a Republican fantasy?
Super common. I’m not sure how that’s any different than teams who create a PR, beg someone to review it, they glance it for 3 sounds and leave a “LGTM!” approval so you can finally merge to main.

Same result, whole lot less performative bullshit.

We use branches and reviews for large changes. Small scope changes go directly to main. If it breaks, we rollback and tell that person to stop breaking things.

Also GDL and its variants, but that is more of a domain-specific language for game descriptions and general game-playing runtimes. Still, they refer to Datalog as its basis.
Was that a Chinese SIM or a foreign SIM in roaming? Hong Kong SIM cards are an effective way to circumvent the Chinese firewall, and, if you don't mind the prohibitive cost, they work against the Russian firewall, too.
What you ignored was a confrontation but made assumptions and judgements about the person, their work, and their ability to work from home and concluded the issue was with working from home, without providing feedback or attempting to learn more about the situation, and then complained on the internet. How would you like it if your work performance/feedback was handled this way? IMHO, I don't think that's a very professional way to handle a work issue/relationship. I would have been more sympathetic to your issue if you had made an attempt to provide feedback or tried to resolve your problem, and if the other party failed to help.
To have 37 different implementations to achieve this, might be a feature. To have 37 different protocols surely is not.

There should preferably be one open protocol for proximity based wireless ad-hoc file sharing. This protocol can then be implemented by operating systems and/or userland implementations
No, it's very true that the customers are better at finding bugs than QA is, because there are more customers and they try a ton more weird crap.

The problem is that, unlike QA, the customers sometimes stop paying you when they discover bugs.
"Do you like Raffi? I've been a big children's music fan ever since the release of his classic album, "Singable Songs for the Very Young." Before that, I really didn't understand any of the kiddie tunes. Too jingly, too toddler-tastic. It was on "Singable Songs" where Raffi's catchy melodies became more apparent. I think "Baby Beluga" was the artist's undisputed masterpiece. It's an epic lullaby on ocean adventures. At the same time, it deepens and enriches the meaning of the preceding three albums. Teddy, take off your PJs."
I'm excited for all the future musicians who might have been [at least partially] trained by excellent AI teachers.

I believe the better idea is to put a regular nuclear reactor on a regular ship some 20 miles off the coast and then find a way to make an high voltage transmission line to land, to deliver electricity.

At the first signs of trouble the ship can power up its regular diesel engines and go in the middle of the ocean so if a meltdown happens it's a solved problem already, in the worse case scenario you sink the ship and that would be the end of it considering how water is the best radiation shield and the ocean is immense

It could be a nice option to finally convince people to give nuclear a try, the fear of meltdown is engrained in their minds so no matter how many reassurances and design models you give them they'd always be in panic mode, so the answer might be to just say 'okay if meltdown happens it's going to be 1500 miles away from the coast, in the middle of the ocean and we can immediately bury the whole thing under 6 miles of water.

Ops 'N' Hops: Terraform, Licensing, and Platform Engineering with Matt Gowie [video]
I always felt sort of embarassed that I use mc 24/7 for everything. I live in it. It might as well be my login shell. I even use mcedit for about 80% of text editing outside of geany or codeblocks.

I don't have any actual reason to be embarassed, since I'm actually perfectly comfortable in vi and and the command line on some old sco box without mc available, it's got to be just because I started among guys who themselves were even older unix guys who never touched anything like mc. Also it felt kind of like still using training wheels when I had been using xtree on dos before encountering unix. But hell I started on xenix myself and still miss some features from ksh93 vs the latest bash5. I haven't needed to live up to anyone else since forever.

But embarrassed or not, I used it all day every day since the late 90's at work and home. It just makes the most sense to be using essentially a browser for that.

For one thing I simply see more stuff.

In the past, every day at work I'd see random junk left all over the place by other employees who clearly didn't even know that they had created these junk files and directories all over the place from having flubbed the syntax of command lines, or botched quoting or escaping inside programs they were writing. Files with names that looked like various other bits of command syntax from quoting mistakes etc. And still sitting there because if you don't actively ls, then you don't see it. I was constantly cleaning up stuff like that back before we finally went to individual developer vms.
If I'm going to be on the hook for the work, you bet I'm taking 30% minimum!
Trading and finance. It makes sense that they are crypto friendly, given their close proximity to it.

I suspect the rest of the commercial world will become much friendlier to it as more and more businesses are onboarded.

The pros vastly outweigh the cons and if you need something like escrow (or another trusted intermediary) then you can always revert to the legacy financial system for that. Both have their use cases.
Buying a house and eating are choices, too, I suppose…
Completely agree. Friends who work in the shoe trade industry also say it’s nonsense.

Jordans have been and continue to be one of the most sought after shoes for people’s collections.

Edit: yes, it’s wild but there’s a market for collectible shoes and if you google around you can see how lucrative it is for folks
This is wild. I don't think I have once even looked at someone's shoes. Much less identified them. This is so alien to me.
Agreed. Horrible idea to broadcast our position like this. But hella exciting
There is also the question of new mass media.

I would hazard a guess and say if you look at AirBnB throughout major cities in the world, the aesthetic will largely be the same. Trends existed before but were often adapted to local taste, yet now everywhere has the same overpriced coffee shop with rustic wood/metal tables and edison bulbs.
Something I've been wondering:

> [When you loose weight], your body looks for ways to conserve energy. Your muscles work more efficiently, for example, Ard says, so walking that normally burned 100 calories might now burn only 90. By making you want to eat more and burning fewer calories, your body is eventually able to slow weight loss down to zero.

How exactly is your body able to accomplish the same task with less energy? What are you giving up? Do you become tired more easily, or wear out your muscles more quickly? Or does loosing weight just turn you into a more efficient super-human (albeit perhaps not in a way you would like)?

Would it be desirable for, say, an ultra-marathon runner (who I assume needs to consume as little energy as possible) to spend a year gaining and then loosing a bunch of weight, to make their body more efficient?
Applied Ion Systems is throwing these kind of rocks with small-scale electric space propulsion. It's interesting to see both the excitement and energy from eager researchers and hardcore hobbyists (cubesat folks), and the oftentimes rude and nasty pushback from industry.
