The peak generating capacity is off the charts and most of the largest plants are situated next to pumped hydro to give storage.

You've probably heard that solar installation is exponential and that it's now cheaper than nuclear even with storage and transmissions costs factored in and this is a great way to see it and understand it. https://reneweconomy.com.au/csiro-says-wind-and-solar-much-c...

To Install Fossil: Download Executable, Put in Your Path
Just sharing one aspect of my love for the Fossil version control system (from the creators of SQLite) which I've used for 4+ years.

To install it - download a ~10 MB executable binary file, put it in your path, and you've got the entire system (version control, wiki, bug database, chat system, HTTP(s) server and web-based UI, email server, etc.). To upgrade it, copy the new binary over the old one.

This is exactly how software should be!

Why would you have to jump to the conclusion that identity verification is required to implement this law? The simple existence of this law:

- Requires social media companies to implement rules to prevent <16 to sign up/sign in -- the onus is on them to find the solution, not on the gvt

- Enables parents to tell their <16 kids that social media is illegal

- Will likely drive a number of <16 kids to sign out (not all of them of course, but a bunch)

BigTech has been slapped in the face enough in EU to take this kind of law seriously.

It baffles me that they've gained so much power in the collective consciousness that any law that restricts their usage would have to be implemented by someone else.

Show HN: I'm 37 and building a platform to help with anxiety and procrastination
Hi HN,

I’ve struggled with anxiety and procrastination for most of my life, feeling overwhelmed and stuck in cycles of stress. A few weeks ago, I decided to channel this experience into something meaningful: TheInnerAlien.co.

It’s a platform designed to help people like me manage anxiety and time overwhelm through structured tools, personalized systems, and a supportive community. It’s still early, but I’m excited to share it and hear what you think.

Here’s the link: http://www.theinneralien.co

I’d love your feedback or ideas on how to improve it. Thanks for taking a look!
> - Writing to a fresh file is slower than writing to an existing file

> mold can link a 4 GiB LLVM/clang executable in ~1.8 seconds on my
machine if the linker reuses an existing file and overwrites it.
However, the speed decreases to ~2.8 seconds if the output file does
not exist and mold needs to create a fresh file. I tried using
fallocate(2) to preallocate disk blocks, but it didn't help. While 4
GiB is not small, should creating a file really take almost a second?

1s difference here is insane these days. There must be something weird going on, even if the physical disk is one of those ancient spinning things.

The highlighted saturated links are a nice touch.
The benefit of allowing one nerdy kid unrestricted access to the internet is often larger than literally hundreds of people “harmed” by that very same access.

Trying to kill the pipeline for creating the “hacker” mentality that folks here are supposed to have is supreme level bootlicking. I hope you eventually find it disgusting.
I was going to say it looked like a Cannondale TT. It was too stiff, unstable, difficult to control, and rode poorly compared to heavier steel frames. Steel is heavier but at least you'll still have teeth left after a ride on a road that isn't perfect like a freshly-asphalted bike path.
Which will probably work as well as most apps implemented by the Australian Govt; myNDIS, myGov, myMedicare etc etc etc. They are all trash. We do not have a good track record in this area.
I would rather title it as: Social media companies to be banned from destroying the lives of minors.

Let's not swap the violators and the victims.
> Are you suggesting porn, violence, and other mind bending content is not present on social media?

If protecting kids from porn is the objective, the most obvious thing to do would be to require age verification for porn sites, not some other random websites that happen to have occasional porn.

Ironically, kids will now have to visit much more hardcore sites (4chan etc - ones without age verification) if they want to socialise online. The effects will be similar to banning alcohol, it doesn't decrease demand, just pushes it elsewhere creating worse problems along the way.

Hello HN, I made Kurdle, a daily kanji challenge game similar to Wordle, where a vowel in the active word is masked by a kanji of the same meaning.

For example, yesterday's word was "CAUSE" and the A in "CAUSE" was masked by the kanji 由 meaning reason, origin, or source.

Each day the kanji will rotate, this ties in to my platform Japanese Complete, where we teach 777 kanji to get learners to 90% coverage of "kanji in the wild," based on our data-driven approach that leverages the insights of the BCCWJ (the Balanced Corpus for Contemporary Written Japanese).

Have fun! I would love to hear back about the execution and design.
> My personal hunch is legacy media is largely driving this, due to them seeing the writing on the wall and knowing 'social media' is their biggest threat. If young people get their information from sites like bluesky, twitter, podcasts and reddit, they may never watch a mainstream news program or read an online newspaper. Bad for business. This measure is a great way of eradicating some competition.

I wonder, I often see legacy media companies complain about how "new age" media (podcasts, social media, etc) is taking over. Social media has been prominent for at least a decade now and so have Podcasts. Why have so few legacy media companies looked at the writing on the wall and invest in the "new age" media instead of complaining about how it's eating at their business.

I would say NYT is one of the only media org's I've seen execute on this.

EDIT: I thought about my question a bit more and my answer for why they haven't is a "new age" media org would look very different from a traditional media org. But that just brings me back to: THEY HAD OVER A DECADE TO ADJUST.
We use Knex a lot because it can be used dynamically. All newer systems are based on typescript, which is great, but not dynamic unless you do code gen. And that's quite a lot slower because of the compilation steps in our experience. With Knex we can have users building a massive query dynamically while seeing intermediate results immediately.
Then the user should be able to post exactly what they posted to get banned without fear
Gonna assume it's because you have to disable it to run your operating system of choice, unless you beg Microsoft to let you.
It's worth noting that Bluesky has exponentially grown to 23MM users on the back of changes that increasingly force X users to engage with what begins as a minority of trolls.

These types of users are not some noble vanguard of the free speech of the wise masses, or whatever else proponents try to portray them as - quite the opposite. Who do you actually know IRL who's a bitcoin-obsessed tradcath neo-nazi?

The "freedom of speech" being afforded here isn't going to the benefit of scientists or economists with technical misgivings of a small part of some overreaching left-anarchist agenda. If it were, the "free speech" crusade would be much easier to understand. But for every Jordan Peterson, there's twelve Nick Fuenteses, being treated as if their opinions have the same value. These types of users are a very vocal minority exceedingly committed to flowing a firehose of low-quality, sneery, fact-free, outrage-bait content. And fewer and fewer people are interested in any of it.

"Free speech" is the government-level abstraction. Private platforms are better to moderate their service, because this specific contingent ruins every platform they're permitted to dominate. It's the Nazi bar problem in a nutshell.

X's usership is dropping like a rock[1] as Bluesky's growth surges[2]. Nobody wants to be forced to engage with these types of users, and the trends demonstrate this. If I were one of X's investment partners, I would be fuming at Elon's abject squandering of my perfectly good investment capital.

If this is the platform Elon actually wants, then fine and dandy. Just don't complain when the result is different than what you expected and huge amounts of people leave instead of assimilating to the hivemind.

> Opposing a social media law “violently” is not an appropriate call to action.

Every single ounce of freedom you enjoy today was won with bloodshed. There is nothing extreme about reminding your local legalized mafia who is actually in charge: the People. Your compromised governments work hard to condition you to think otherwise.

Direct political violence should always an absolute last resort, when every other realistic option has been exhausted. However, every freedom is ultimately backed by threat of violence, even when it isn't said aloud.

> The laws are a response to a real issue

They use a real issue as a vehicle for tightening the authoritarian ratchet. All good antidemocratic legislation is wrapped in legitimate issues. But what authoritarian governments such as Australia fear is the power of unification which the internet offers new generations.
Add the source, please.
The parent comment suggested of the sort. There is obviously more porn on porn sites than on moderated social media platforms. Pointing out that some porn occasionally evades filters on Facebook for a couple days doesn’t mean social media sites and porn sites are fully equivalent.

> For me, social media is the worst thing we ever created.

Calling social media the “worst thing we ever created” as a comment on a social media site is deeply ironic.

I can’t believe how many commenters are assuming these laws will only apply to sites they don’t personally use. The amount of “good riddance” commenting from people inviting heavy handed internet ID checking regulation because they can’t imagine it would ever affect them personally is really scary.
>The writer Umberto Eco belongs to that small class of scholars who are encyclopedic, insightful, and nondull. He is the owner of a large personal library (containing thirty thousand books), and separates visitors into two categories: those who react with “Wow! Signore professore dottore Eco, what a library you have! How many of these books have you read?” and the others — a very small minority — who get the point that a private library is not an ego-boosting appendage but a research tool. Read books are far less valuable than unread ones. The library should contain as much of what you do not know as your financial means, mortgage rates, and the currently tight real-estate market allows you to put there.

Hypothetical example: When I open Twitter in the browser, I see a feed - but I also see a "What's Happening" section, and a "Who To Follow" list of suggestions, as well as what looks to be my inbox, minimized. Plus, the feed itself automatically loads the images that people are tweeting.

If you know a client is likely to be from a place where bandwidth is expensive, you may choose not to load the "What's Happening"/"Who To Follow", or the messages, or possibly even the image URLs (which I'd guess come from the backend with an array of URLs of those images in various sizes & resolutions.)

Hell, you might even load a smaller subset of the feed - 10 items instead of 30.
> the Aus Govt will be able to access citizen social media data with relative ease. So no more pseudo anonymous accounts

This isn't necessarily true.

It came as a surprise to me, but many "Government Digital ID" systems use Verifiable Credentials[1][2] and Decentralized Identifiers[3].

I live in BC, Canada. I have installed the BC Wallet app[4] which is open source code[5].

With the BC Wallet app, I can create an account using my BC drivers license.

Then I can interact with any third-party app that uses the BC Wallet as an authentication system. If the only thing this app wants to do is confirm my age, it can ask me to reveal my age. I reveal my age (the only piece of data I am choosing to reveal), and the app now knows and can trust (as long as it trusts the BC Wallet) that this is my age.

And the BC Wallet app servers/government never know when I am using the BC Wallet app.

Turns out the future may not be as dystopian as we once thought it may be.

EDIT:

I see now from the article the following:

> Social media companies also won't be able to force users to provide government identification, including the Digital ID, to assess their age.

What could have been privacy preserving seems like it won't be.

Grinding leetcode is kind of the same as grinding college classes, where you memorize material, get a passing grade, then forget as much as possible.

Doing leetcode type problems, reflecting on what else can be learned, trying to draw general conclusions about programming techniques and what an interviewer might be getting at with a problem can have some benefits.
> Lots of state governments, Florida notably, quit collecting COVID mortality data.

And lots of state governments counted deaths with COVID as deaths from COVID... what is the point? As long as the data is presented correctly and represented properly, it remains as it is. In the discussion above, there's no reason to disbelieve the data. The collection and meaning is clear.
This piece by Christine Lemmer-Webber mentions Christine's very positive experiences working with Jay Graber. I consider CLW to be a reliable and trustworthy source of information, so I think it's relevant here.

> You generally shouldn’t use absolute paths in your programs.

This is true, but I was enjoying the irony that there is an old sys-sdmin adage that you should only use absolute paths in your program(usually a shell script, in this environment) this is to make sure it is running exactly what you expect it to run.

So always put "/usr/bin/awk" instead of just "awk"

I had a co-worker once who took this as gospel. His scripts were always... interesting... to port to a new environment.
