I don't think the panels are the limiting factor. Remember this isn't a photoelectric plant; the sunlight isn't being converted directly into electricity. All the panels are doing is reflecting sunlight to the central tower, where it heats up molten salt. The limiting factor for power generation is probably the heat capacity of the salt, not the amount of sunlight the panels can reflect.

Also, the panels don't look like flat squares to me; they look curved, so that they concentrate the sunlight they reflect.
This militancy to force everyone to use UTF-8 is bad engineering. I'm thinking of GNOME 3, where you aren't even allowed the option of choosing ASCII as a default setting, only UTF-8 or ISO-8859-x. A default setting is just as important for what it filters out as for what it passes through. I use a lot of older tools on *nix that are ASCII-only, in tool chains that slurp and munge text. If the chain includes any of these UTF-8-only apps, I'm constantly dealing with the problem of invalid ASCII passing through.

I know it's a rant, but open source people do not know how to do user-friendly user interfaces. A few days ago, I posted the home page links for Diaspora, Gnu Social, and Friendica, and commented "any questions".

Blatant UI bugs often don't get fixed in open source. There's a bug in Ubuntu on some machines which causes the cursor to disappear after coming back from a suspend. (You can get the cursor back by typing CTL-ALT-F1 / CTL-ALT-F7.) The bug has been reported repeatedly for five years.[1]

With enough code bloat, all bugs are deep.

The amount of storage depends on the camera's resolution and frame rate.

One of my cameras records 640x480 at 1 fps, saving movies at 7 fps when motion is detected. I end up using 1GB to 1.5GB per camera per day, depending on how much motion is being detected. The files saved are 7 fps videos for each event, 1 fps videos for each hour (24 videos), plus the event videos all stitched into one video.

For my purposes, this is sufficient. Other folks might want 720p or 1080p video, have more cameras, etc, and have correspondingly larger storage requirements.

I'm glad the author of beet uses Sqlite, but to use a client/server database system would be ludicrous!

Sorry I don't have exact numbers for you, but there do exist some very long HVDC lines [1]. The longest as of writing is in Brazil at 2385 km. There is a fairly long one in the US at 1360 km between the Columbia River Gorge and the Los Angeles basin [2].

But given that the solar terminator moves at about cos(latitude) * 1668 km / h (so slower towards the poles), even at a generous mid-Europe latitude of 45° N it'd be moving at 1180 km / h, giving you only a 2-hour window to make use of such a scheme with the HDVC lengths we have now. But hours before sunset, you're probably not at peak solar production anyway.

He could also take drugs tomorrow and stop the next day. Us addicts seemingly think of relapsing as something that happens to you, like if you're walking down the street and fall into a manhole. But you're not powerless, it's just a self-fulfilling prophecy. It'll take at least weeks of continued use to get addicted again (that's for opioids, amphetamines are not addictive in that way.) Then again, it's never enough to just do it once as you want to be on the drug forever. This is why it's easy to continue using again, but it's also possible to stop.

EDIT To clarify: I'm not condoning relapsing, I only want people to know that all hope is not lost if you made the decision to use again. I'm also not saying that it will be easy to stop again, just that it's going to be easier than you think.
> Lee and other speakers at the event pointed out a key problem of the Web today is its ephemeral nature

Why is it a problem exactly ? If something great appears on the web it will be shared, saved and discussed and not forgotten. If something is useless or bad, it will be lost when the server stops, and that's good right ?

Same happened with paper books the last 2000 years, great one were replicated, shared etc. others went lost.

The FCC (i.e. US) has enshrined such baud rate limits into law, regardless of technical capabilities within the bandwidth used. I don't believe such a limit exists in Europe.

Yeah, basically it would've had to specify all of SQL, or to say "do what SQLite does", and neither option was very palatable to all the parties. Some browsers [1] did implement WebSQL before it was formally abandoned, though.

Interesting; although it appears as linkbait on initially reading the title, I'd argue that the articles central thrust is accurately represented by its original title - therefore counting as neither (using a definition of linkbait as a title to drive clicks that is not representative of the article).

The article isn't arguing just that photography is changing, but that Apple is stuck in "The past".
> Also, APFS removes the most common way of a user achieving local data redundancy: copying files. A copied file in APFS actually creates a lightweight clone with no duplicated data.

No, it doesn't. APFS supports copying files, if you want that. It's just that the default in Finder is to make a “clone” (copy-on-write).
Classic HN bait.

You don't even need to read the comments to know what people will say:

The larger engine isn't going into this rocket.

This appears to be a desktop application, so SQLite seems like a good fit. Although if some people are requesting it perhaps they have their reasons. For example if I had RDBMS already setup with proper backups I would generally prefer to use that, since there's no effort to make yet another allocation use it. It most likely would also enable me to have access to the same databases from multiple computers. With SQLite you would have to solve the same problems again (e.g. store the database in Dropbox account, and deal with shortcomings of that approach)

IMO instead writing how SQLite is the best choice for the project I think it would be better to add support for multiple backends. Something that is good for you and majority of users does not mean it's good for everyone.

Apple Releases Swift Playgrounds Teacher Guide: “Siri Says Kiss Your Tummy”
What a great and valuable post, especially since this info is the result of talking to the APFS team at WWDC, and has not been published anywhere else yet.

Of particular interest (to me) was the "Checksums" section:

Notably absent from the APFS intro talk was any mention of
checksums....APFS checksums its own metadata but not user data.

...The APFS engineers I talked to cited strong ECC protection
within Apple storage devices. Both flash SSDs and magnetic media
HDDs use redundant data to detect and correct errors. The
engineers contend that Apple devices basically don’t return
bogus data.

That is utterly disappointing. SSDs have internal checksums, sure, but there are so many different ways and different points at which a bit can be flipped.

It's hard for me to imagine a worse starting point to conceive a new filesystem than "let's assume our data storage devices are perfect, and never have any faulty components or firmware bugs".

ZFS has a lot of features, but data integrity is the feature.

I get that maybe a checksumming filesystem could conceivably be too computationally expensive for the little jewelry-computers Apple is into these days, but it's a terrible omission on something that is supposed to be the new filesystem for macOS.
A make-like build utility for Lua: xmake
I don't agree with the article. As others have already said here, text is random access and easy to process and retain information.

I am going to drift off topic: the future is AI that understands what we say, recognizes our facial expressions, and generally "gets us." While there are obvious potential downsides, the upsides involve getting notified of things in the order of most useful and entertaining first. AIs will use text, still photos, and videos to show us what we want to know and experience. This whole idea creeps me out a bit, but it is probably the future. At some point in time, effective computer to human neural I/O connectors will be invented, and the effect of civilization will be interesting. So, video -> direct neural implants.

>Only the government can do that.

Why would the government want to spend the money and PR capital developing and rolling that out, when they can have a company do it for free, take the heat, chest beat about private enterprise, and then secretly NSL subpoena or crack it and distribute the intelligence to every interested agency, police department, and eventually favored corporate interest (using parallel construction as needed)?
You should read about the implementation of IPFS and how it tackles this exact problem. Look it up, it's readily accessible from the first few results in Google.

I believe their system will work. Or require only minor tweaks.
That's not the only problem. You'd have to get the cooperation of many different countries who don't necessarily like each other. The political obstacles would be greater than the technical.
Downvoted. Addiction is powerful and the false belief that you can "just dabble" is what causes a lot of relapse. It is a common excuse/justification for people during a relpse.

If you are speaking this way from a personal perspective you should take the resumption of addictive behavior seriously and consider getting help.

Flippant attitude toward relapse is not a good attitude for someone who wants to stay clean.
To me it sounds pretty much like the court sent him to Narcotics Anonymous and he got clean there. The sober living house had him pee in a cup to verify he was staying clean and that's about it.

Clarification: You can have multiple connections (aka file descriptors) open on the same database file for writing at the same time. But only one can be actively writing at a time. SQLite uses file locking to serialize writes. Multiple writers can exist concurrently, they merely have to take turns writing.
I quite like Swift's approach -Characters, where a character can be "An extended grapheme cluster ... a sequence of one or more Unicode scalars that (when combined) produce a single human-readable character.". This seems, in practice to mean things like multibyte entries, modified entries, end up as a single entry.

As the trade-off, directly indexing into strings is... Either not possible or discouraged, and often relies on an opaque(?) indexing class.

The main weirdness I have encountered so far is that the Regex functions operate only on the old, objective-c method of indexing, so a little swizzling is required to handle things properly.
NTFS Shadow Copies are more like LVM/ZFS snapshots than APFS's file-level CoW snapshots, in that they both operate on the entire volume at block-level, rather than having a per-file level of granularity.

There are other FSes that allow the behavior that APFS is demonstrating - look at OCFS2 and Btrfs, both of which allow you to do cp --reflink.
Expensive indeed. I wonder how concentrated solar thermal compares with a simple photovoltaic plant these days? Given the precipitous drop in price for PV panels, even if solar thermal is currently cheaper, how much longer until it's just not competitive?
Classic comic, but I don't think it applies. APFS looks intended to solve Apple's product problems really well, and it doesn't even try to be a filesystem for everyone.

Apple has said from time to time that they're all about owning and controlling the key technologies that go into their products. APFS makes a lot of sense from that perspective, and this seems one of those cases where going their own way is better than importing someone else's constraints. ZFS on an Apple Watch? LOL.
> It'll take at least weeks of continued use to get addicted again...

Maybe that's your experience, and maybe it's some other people's too, but to offer this as a blanket truth is not merely wrong, but actively dangerous.
I think this kind of defines the line between an addict and a user, doesn't it? If you're an addict, you can't just 'take it or leave it', or 'just stop'.

I think the meta concept here is "congruence".

Once one gets something nice, you're trying to maintain parity between that part of your life, compared to the other parts of your life, and you're willing to spend moeny to do so.

From C.S. Lewis:

"The man who truly and disinterestedly enjoys any one thing in the world, for its own sake, and without caring two pence what other people say about it, is by that very fact forearmed against some of our subtlest modes of attack. You should always try to make the patient abandon the people or food or books he really likes in favor of the “best” people, the “right” food, the “important” books. I have known a human defended from strong temptations to social ambition by a still stronger taste for tripe and onions."

If you really like something, with a strong sense of self, you stop caring about how all your stuff matches together.
APFS is targeted to run on low-powered devices like the Apple Watch. It may be that the alternatives cannot be made suitable for such devices: ZFS is famously memory hungry, HAMMER says it's not designed for < 50GB devices.

> "But in reality most people just want to be told what to do because making decisions and being responsible for it is not an easy thing."

As I said before, content could be curated by apps. You could choose the apps that present the information in the way you like. The difference is, if a better app comes along you can switch to it without losing your past data because all the data would be application-agnostic, there's a greater degree of separation between the raw data and the presentation of that data.
On the plus side tmux is a BSD style license and not GPL. So it is a more free (as in libre) software.

Edit: I guess that was obvious considering this gnu screen announcement contains as much (or more) discussion about tmux as screen.
