I mean, we definitely can. We see stars that are thousands of lightyears away! However, maybe OP means "receive" as "response to a message we sent". This is indeed something we are able to do since ~100 years, so our communication bubble is currently ~100 lightyears.

Well the context in my replies there is clearly only talking about Cryptocurrencies here. I did not mention anything else.

> Still i am wary of crypto investments, easy to get burned.

So, since I stayed away from the late Bitcoin mania up to >$60K (and DOGE) and warned others, I am downvoted?

This is why people get burned because they don't understand these 'investments' and join in when it is late, or when Elon Musk and Tesla start a pump and dump scheme and baghodl at all time highs, which is what I am talking about.

I am now congratulating the BTC short-sellers who took advantage of the sea of red in the cryptocurrency markets just 12 days ago. [0]

Pretty cool to peruse for a while. Notable:

- No major website launches since 2015 while before that since 1995 barely a year has gone by without one. Because it's all apps now? Eg Tiktok

- Average cost of broadband in Eritrea (?) is 2'600$?
I think the issue here is that 35Wh per transaction is still a million times less efficient than traditional databases. The MacBook example is just meant to give a frame of reference for how much 35Wh is.
> That's greater than Bitcoin's energy usage.

For now. Gold's been around for centuries, Bitcoin not even for two decades. It's got a momentum that Bitcoin may or may not match in the future.
In Germany this paper is just that, a paper. It has 0 safety measurements. You can get blank ones for cheap, via the internet or your doctor. From Biontech or the other vaccine manufacturers you can get the blank charge number thingies which you can then stick onto the paper. You have to fake a signage but nobody can tell whether it's fake or not.
> "Things that go up for no apparent reason can come down for no apparent reason."

Many of the previous sharp increases do have explanations, e.g. the $150 to $1,500 rise was largely due to manipulation by the Willy and Markus bots[0], the $10,000 to $20,000 rise was largely due to manipulation by Tether and Bitfinex[1]. Will probably take a while for the dust to settle to see if any manipulation was responsible for the recent rises.

> I'm not a fan of China's actions but your post is both mis-informative and ironic given that every one of your points apply to the U.S. at various points in time.

It is neither misinformative or ironic, and it's clearly talking about today and in future.

> The U.S. produces roughly double the emissions of China per capita.

I'm not talking about per capita. Per capita is about the worst metric to use for this, because 1. the environment doesn't care about per capita, it cares about total emissions, and 2. acting like lower per-capita is better creates perverse incentives to increase population and suppress quality of life. Carbon intensity is the relevant metric.

> Ignoring population is a gross misrepresentation of the facts.

Rubbish. I'm talking about facts that have no relationship to population.

> As for bullying neighbours, the U.S. lost both those legs after a long string of funding terrorists, assassinations, and aggressive wars.

That doesn't address what I wrote I'm afraid. I never said "China does this and USA does not".

> Wikipedia has a quote from Alexander Hamilton:

Also irrelevant. America (and almost all the world) had slaves. That doesn't stop me from saying any nation that uses slave labor will never be a leading country and will always be looked down upon, at least until [the use of slave labor] is dismantled.
If you have been creative with algorithms then you will have the fundamental ones in your head. Every time you add layers the last layers needs to be really stable, so testing the layers they need to have built upon is a good way to filter out people who haven't progressed past that layer.
So, is it too crazy to think that prisoners need to pay for the accommodation, food, electricity, water, etc. that they receive while being in prison?
Because of the very large amounts of energy to transmit information in all directions from such a large distance. Also because it's such a stupid waste of energy. Why send radio waves out in all directions in order to communicate with a neighbor? Use a light beam instead.

So the lack of huge radio transmitters that we can detect really just means aliens aren't investing huge amounts of money into letting us know they exist. Why would they? Especially if they already know of other civilisations.
Yes.

And using a key like this isn't even two factor.
No, nothing complicated, just pre-made, randomized feedback (so it doesn't sound exactly the same every time) for when I feel real bad. Triggered by multiple keywords when I speak.

It's like talking to myself, which is what I've always done and it's always the same conversations. So I automated it.

Now half+ of it comes from outside, which seems to work better even if it's a synthetic voice with messages I made.

I also used it for nagging medication reminders, as I kept forgetting what, how and when to take (at one point it was... quite a lot, on an overly complicated schedule).
Exactly on point, which is why for interviews I like to discuss code snippets. Asking what's wrong here, is this the right collection type to use here, what would you do instead, how would you refactor this.

I do like to ask algorithmic questions, but I don't expect the algorithm in detail. Instead I want to know if people understand when to use it, and what is the principle behind it. Because while you don't need to implement your own collections, you should know what their advantages and disadvantages are.
Well...you're in luck!

I'm glad you are having a good experience, but people work on different projects with different requirements and different constraints.

In Go, empty interfaces and reflection, or templates, are for some cases the only possible way to solve a large class of complex problems. If you don't encounter those problems then it's all good, but some people do.

You haven't also taken into account the possibility of people having to maintain pieces of Go code acquired or forked from somewhere else. Maybe my team was the one who inherited the code from someone who "perpetrated some empty interface crimes".

Not all Go development is greenfield development.

This is one of the things I dislike the most about the Go community. Every single criticism or suggestion to the language is dismissed as being user error, without even taking into consideration the use case or the different experiences one might have, or if the codebase was gotten from somewhere else, or even acknowledging that there are other programming styles. It is a giant echo chamber with people constantly saying "works on my computer".
Assuming this is a business, you're already spending thousands per machine per user.

And a developer that's down for half a day from a failed key is way more expensive than that $10 of savings.

I really like this article and I love the analogy with music theory, which seems spot-on... but there’s one big difference, which is that you absolutely do not need to know music theory to be a professional musician!

At least in pop music, plenty of successful bands (maybe even the majority) don’t know music theory, they just know how to make music that sounds great (through natural talent and/or hard work).

There’s even a school of thought that music theory is actively bad for pop musicians, as it will tend to steer you down well-trodden lines and stifle innovation. For example, Paul McCartney supposedly avoiding learning any music theory when he was learning the piano, specifically to avoid losing his originality. He got the words for Golden Slumbers from an old piano piece belonging to his sister, but had to write an awesome new melody for it because he couldn’t read the music! (see https://www.the-paulmccartney-project.com/song/golden-slumbe...)

I think the analogy still works, though. To play in an orchestra you absolutely do need to be an expert sight-reader, and ideally have a good grounding in music theory. So working at Google or Facebook would be analogous to playing in an orchestra. They don’t want buskers, they want somebody who can read and understand a Messiaen score.

And maybe a small startup is more like a rock band -- you can get along perfectly well without any theory training. But if you want to grow into an orchestra (or in tech terms, more like 100 or 1000 orchestras) some theory training is essential.

Also, even in a small group, a mix of backgrounds can be beneficial -- look at the Beatles again, where George Martin’s classical training was a significant part of the overall mix (not to say a key part; Martin was the fifth Beatle at best).
These are not that kind of structure. The term "frame" is used in lots of contexts, e.g. these days in pandas' data frame.

By coincidence (with your question) Marvin later became Bob's PhD advisor. And at the time Claris works was being written I was working on a frame system with Marvin.

"Alcohol is addictive. More so than most other drugs."

Alcohol withdrawal can be nasty. But it takes years and dedication (usually) to build up an alcohol habit that threatens serious withdrawal symptoms; for the most part, "withdrawal" is simply a hangover.

Contrast with a minor tranq such as diazepam: you can easily acquire a habit from which withdrawal is potentially life-threatening, in as little as a month.

OTOH David Murray (The 8-bit Guy on YouTue), who is leading the Commander X16 project, does have a strong history of executing well and shipping.

I haven't been that interested in other "new retro" computers, apart from the ZX Spectrum Next (which at least retains 100% compatibility, and for which I have significant nostalgia), but I'm interested in the Commander X16 simply because I tend to enjoy David's work in general.

> Does this account for the goods exported from China to the US? These should be added to the emissions caused by the US.

No they shouldn't, China sells products in the global market. The emissions belong to them, along with the price they charge for the product.

> The west exported much of their environmental problems to poorer nations, including China.

Well, globalist corporations and politicians exported their environmental problems, I agree. The solution is not to give dirty polluting countries a free pass, it is to account for the externalities in tariffs.
Codeacademy for No-Code Developers
A Gamified hands-on learning platform for No-code developers.

Pain point: No-code courses learning experience is frustrating because students need to go back and forth between the screencast/video and the No-code tool where they actually perform the actions explained in the video

Solution: Interactive no-code tool that works on top of Bubble.io. A new fully-guided way to learn how to build projects without writing any code.
Technically speaking: a chrome extension that works on top of No-code tools.

I manufacturer my OSHW in Shenzhen and ship from there, shipping was far cheaper but thanks to Covid that's becoming less and less true, largely because the really cheap shipping was essentially people filling empty space in air-mail containers - and there's so fewer planes flying there just isn't that space. I'm now charging my customers a surcharge (but eating half the extra cost) - it still costs half of what I'd pay if I were shipping from here in NZ.
What I would love is an affordable Amiga 500 clone. Extra points if it can also work as an Atari ST. Anyone knows if such thing exists? By affordable I mean 100~200 USD. HDMI and SATA for SSD/HDD. Thanks1
> 95% of every web app, mobile app, or native app is just very basic stuff.

But 5% isn't, and can absolutely derail a project.

I'm a consultant that goes to various orgs to help them with a huge variety of things, much of which boils down to fixing issues with "simple web apps".

I literally cannot remember the last time I saw any application, written in-house or by a vendor, that had even the basic set of essentially mandatory indexes in the database. I don't mean clever stuff like partitioning, or sorting tables by a column other than the primary key. I mean that most of these databases had no indexes at all on 100M row tables. Just a week ago a large software vendor argued with me, stating that it's absolutely fine to require 10 GB of parallel table scans to display one web form to one user!

That in my opinion stems from a lack of understanding of what a B-tree is, how it works, and how databases utilise it.

That's firmly in the "fundamentals of programming" that every developer writing "simple web apps" should know, and in my experience almost none do.

These people go about their work every day with a firmly held belief that the database server is essentially a magic black box that can never be understood.

Is that okay?
Freenode Privacy Breach Report
Just before 0900 UTC+1, there was this broadcast report of a privacy breach:

08:54 -!- ChanServ [ChanServ@services.] has quit [Killed (grumble (My fellow staff so-called 'friends' are about to hand over account data to a non-staff member. If you care about your data, drop your NickServ account NOW before that happens.))]

Freenode has a history of community communication when things go wrong. There has been only official silence on this so far. There is heated discussion on #freenode.

Direct links are broken on Planet Freenode's blog, but the article "Changes to the organisational structure of freenode" on the Staffblog seems related: https://spamcheck.freenode.net/ .

I worked with Rob Levin (lilo) back in the day, and I'm moving on from Freenode.
> E.g. you can turn on/off wifi in quick settings for both, but on Android you can get to your wifi settings by long pressing the quick settings button, but in ios you have to open and navigate through settings.

This is false, you can do the same on iOS nowadays... Long press the WiFi icon from the tray (after expanding the WiFi/airplane mode/Bluetooth widget box) and you will get to the list of networks.

A bunch of other statements are also not completely true, such as the widgets on Home Screen (or are you talking about some specific type of widgeting feature that iOS doesn't have?).

> ios notification panel has like 3 different modes all with different capabilities and purposes depending on how you open it.

Can you show me this? Can't replicate that in any of my current iOS devices, not that notifications on iOS is good but this issue with Notification Centre has been fixed for a while.

> Scrolling on ios is slower and more jittery than Android these days which surprises me.

How did you measure this? I just went to try this out, scrolled through some browser pages and apps that have infinite scrolling my iPhone 12 Pro Max and my flatmate's OnePlus 9 Pro, no idea what you mean because the experience is, for me, very similar.

> Apps look squished and busy with text with ios' UI. Not always clear what's a button, what's swipable, whether you're deeply nested in navigation or at the top, etc.

This is due to you not using iOS perhaps, I have the same issue with Android after not using it at all for 6+ years, I don't understand the interface and what is interactive or not.

> ios seems to skip loading indicators and just show empty screens, which is really frustrating.

I don't experience this and it seems to be much more a critic of apps you've experienced it rather than iOS as an OS.

I am not an Apple fan, I just use their products because they suffice my use cases, but I feel you conflated some very different issues and subjective judgment stated as facts.

The goal of the interview is mostly that I trust that someone will understand (and listen) when I explain things like this. Not whether they know already.
Polkadot Is Close to Launching an 'Internet of Interoperable Blockchains'
Railsers, if you're perplexed by what's going on here this Rails specific documentation helped me: https://docs.planetscale.com/tutorial/connect-rails-app
Page 6 and onwards: https://equitablemath.org/wp-content/uploads/sites/2/2020/11...

The intentions behind this effort seems to be to promote math that a more diversity of people can culturally relate to. It tries to address problems that today probably makes teaching math to diverse people both difficult and inefficient. The premise is that current practices have evolved in a niche culture, thus more optimized for that niche and not directly translateable to all the diversity of cultures that exists.

However, it makes assumptions and focus around one "problem", which is kind of asking: "When did you stop beating your wife?". The references to "White supremacy culture" raises an indefensible dilemma, being itself racist and discriminatory.

Especially when the focus is so narrow and one-sided, ie. Page 11:

> PREPARE STUDENTS OF COLOR TO CLOSE THE GAP IN ACCESS TO STEM FIELDS

* Teach students of color about the career and financial opportunities in math and STEM fields.

* Encourage them to disrupt the disproportionate push-out of people of color in those fields.

* Invite leaders and innovators of color working in STEAM fields to meet your students.

The stance and focus seems to also be about rooting out negativity, but this can be said of every problem in society and is not an constructive approach in bridging gaps. Statements and mission goals such as these are just dead ends and require circular reasoning to uphold:

> “We live in a toxic culture that affects us all; one dynamic of the culture is that we are discouraged from seeing it. One of our tasks is to learn to see our culture and how it teaches us to make normal that which is not and should never be normal.”

So although you can try to "fix problems" this way, what one inevitably ends up doing is reinforcing all the divisions and problems and make them much larger and insurmountable than they need to be.

It's kind of condescending although they are right: Different people require different approaches for learning better. This goes for all genders and "races" though!
