>Most old people don't learn as many new things as younger ones

... are you sure about that? I'd avoid sweeping generalizations, it does not help your argument.
I have a few 3D Printers, a scratch CoreXY build, Tevo Tarantula, and PowerSpec Ultra (rebranded FlashForge Dreamer) I run prints unattended often. Overnight or leaving my house for errands. The only thing I do is regularly check termination points and board components to see if they are fine.

I wish I knew what was wrong with other people's configurations or the quality/settings of their hardware that causes these fires.

I blame kit providers racing to the bottom to throwing together low quality hardware and passing them off as solid workhorses. For my Tevo Trantula I replaced the screw down terminal block for one with higher amperage rating after noticing some slight melting on the housing, and spent a whole day doing PID tuning for the hot end and the heated bed.

There should also be a bigger disclaimer for kits to deter people who don't have decent knowledge in electronics to just go for complete printers or higher quality/proven kits.

The real question is, why wasn't this article written three months ago? Maybe it was reported at the time, but I certainly never heard about it.

Even now, I think it's more than worthwhile to look at what Microsoft did in version 1809. Completely removing the option to create a local account at setup without disconnecting from the internet is clearly user-hostile. That Microsoft would ship Windows in that state is abhorrent, even if they're fixing it now.
China is really betting on the media coverage helping the pro-China side. They control the narrative and the discussion in official channels but that doesn't mean they control everything. Hong Kong is insular enough that they could become something like Taiwan, de facto independent. I don't see major revolution in Beijing happening anytime soon.
> Low-wage workers are not working for the city.

The minimum civil service full-time pay rate currently for the City and County of San Francisco [0] is a biweekly $1,320, which is $34,320 annually.

Per HUD, for a single person household in SF:

- $33,850 is extra low income

- $56,450 is very low income

- $90,450 is low income

So, yes, low wage workers work for the city (even before considering second order impacts like workers for city contracting firms, etc.)

> The city pays very handsomely (400k police, 100k poop patrol, etc).

I don't believe you have understanding what personal data and GDPR is. You are capturing user behaviour and that is very personal regardless if it is "anonymised" or not - and that is without clear need for doing that. That is pretty much against GDPR.
By how the West seems to precipitate trouble without no clear end game in sight as in Venezuela, Syria and other places, international actors getting involved can only mean moving farther away from solutions.

There is a famous commencement address of Solzhenitsyn delivered at Harvard, I think in the 80s, illustrating how West seems to deeply misunderstand Eastern cultures, but it seems to me, we are where were then, and nothing has been learned.

OK, sorry for the reply to myself, but as a former Clevelander, I have to recommend that anybody in that area pops by the Warner and Swasey Observatory. It remains a striking building, and is blindingly easy to find/get to in Cleveland Heights. It's right in a residential area and it's unfenced. You can walk right up to it.

Yeah that's what I mean, it has to be separated after it's created. There's no naturally-occurring generative complex system that can only generate signal and no noise/chaos.
[Disclaimer: I'm the TL of Safe Browsing in Chrome, and I worked directly with the author of the linked article for Firefox v4 support.]

FWIW, Google Chrome does the same because both Google Chrome and Firefox use the same Safe Browsing protocol v4.
The linked post was written a while ago when Firefox still used the protocol v2 but the post is still largely accurate.
Amazon is also an extra layer of insecurity. Let’s say I buy a widget sold through Amazon by a trusted manufacturer. Some third party is also selling counterfeits. Amazon considers the two products to be the same, and sends me a counterfeit from the third party.

Seems to me that the alternative is simple: mandate that you receive what you ordered, and make the storefront you order from liable for any problems.

Redash is comparable to Superset, Tableau, etc.. Ananas analytics is comparable to Talend, Airflow, etc.
Indeed, the Moon is the best location to develop and perfect technologies to settle on another planet and to live there autonomously.

Because it's very near it's obviously much faster and cheaper to ship things there, and it allows near-instant communication back and forth.

Once the technologies are mature it will just be a question of longer shipping to mars or anywhere else.
They were all good enough to get in person interviews at least[1].

I work for ConvertKit. We’re fully remote and have public, standardized salaries regardless of where you live in the world. Pay is based on title. If you want more pay you need a new title and if you know someone’s title you know their pay. Not all employees share their title because it’s personal but it’s also not a secret.

It’s way more fair than what Gitlab does IMO.

Also our financials are public. We’re bootstrapped and profitable with no outside investment so saying standardized salaries hurt the company is a lazy cop out at best. https://convertkit.baremetrics.com/
It's kind of fascinating how important the defacing of the national insignia is in the reporting in China.

An authoritarian government like China's has no real mandate - they have no right to be running the country and no legitimacy that can be claimed. They're a bunch of men that the army listens to. They have the guns and the power and that's it. With such a government, symbols and flags are the proxies for legitimacy. I don't know whether the translation is faithful, but the vandalism was actually translated to the English word "desecrate". That's some powerful language for wooden sign.
Slack is eventually going to write native apps once they realize that productivity software shouldn't be developed like an ad product from Google. It will take Teams winning because it gets included in the Office 365 subscription for several quarters before they come to the realization that they need to compete on user experience.
Ask HN: Which blog platform is your company using for public-facing content?
I'm curious as to what platforms the HN community are using for external facing company blogs (to post news, opinion, marketing material, engineering posts etc). Obvious choices include Medium or the blogging features of a static site system (such as Jekyll + Netlify). What else?

In 2019, what blogging platforms are people using, and why?
American prison system is deeply problematic too, one which both parties has continually failed to reform.

Perhaps CCP see themselves as guardians of a country, a system thousands of years old. In comparison the existence of the modern democratic West has been for a mere ephemeral duration, and look who likes to lecture whom..
Where are people going to go if they want to do science? OK, the ESA, Japan, India. Maybe China. But is there anywhere else to go in the USA?
Yes, this exactly! I can't believe how everyone is paying attention to such irrelevant things! Like how "Trump's Economy" sets 'records' everyday, or how just because everyone in the United States is making more money and things are turning around, doesn't mean it's a good thing for the whole world. Those people who voted him in are just selfish, they only care about their own kids.
China would be risking sanctions.

Given that their economy is already slowing (dramatically faster than the official numbers by many reports) and their massive debt loads -- sanctions could pack a real punch.
I agree. I made a website which breaks down failures and resolutions.
No, deriving the second law from Newton+Liouville is easy (in the form of "mathematically plausible pseudo-theorem", that's late 19th century physics). If you don't adopt Liouville measure as axiom, then it is impossible by (more modern) counter-example: Thermodynamics looks different if you pre-suppose that god cares about weird measures; and it is unavoidable if you pre-suppose that god cares about Liouville measure.
I definitely see that. It's pretty compelling. You can't deny that certain drugs, for example, are a lever you can pull that makes consciousness go away (or come back). There seems to be a cause-effect relationship there.

But at the same time, I do not understand how it's possible that the consciousness that I subjectively experience can arise from physical processes. Therefore, I have difficulty completely accepting it. I write software. It processes information. I don't believe that the CPU has this same subjective consciousness experience (not even a little) while it's running my for loops and if statements. Suppose I were a genius and figured out an algorithm so that the CPU can process information in a way equivalent to the human brain. Would it have consciousness then? What changed? Does whether it has consciousness depend which algorithm it's executing? Quicksort no, but brain-emulator algorithm yes? They're both just algorithms, so why should the answer be different?

One explanation I've heard is it could be a matter of scale: simple information processing doesn't create consciousness, but sufficiently complex processing does. I can't say that's not true, but it seems hand-wavy and too convenient. Over here we have something that is neither conscious nor complex, and over there we have both conscious and complex, so we'll just say that complexity is the variable that determines consciousness without any further explanation. I realize at some point science works that way: we observe that when this thing happens, this other thing follows, according to this pattern we can characterize (with equations), and we can't get too deep into the why of it, and it's just opaque, and we describe it and call it a "law". Which is fine, but are we saying that this is a law? I'm not necessarily rejecting this idea, but the main argument in favor of it seems to be that it needs to be this way to make the other stuff work out.

Another possible way to reconcile things is the idea that everything is conscious. It certainly gets you out of the problem of explaining how certain groups of atoms banging around in one pattern (like in your brain) "attract" consciousness but other groups of atoms banging around in other patterns don't. You just say they all do, and you no longer need to explain a difference because there isn't one. Nice and simple, but it has some jarring (to me) implications that things around me are conscious that I normally assume aren't. It also has some questions about how it's organized, like why consciousness seems to be separated into entities.

Anyway, there are also other ways of looking at it. My main point here is that it's certainly something I don't understand well, and possibly it is something that nobody has a truly satisfying answer for.

Do you need it to be a commercial service? I just use nfs over wireguard, hosted at home on some old hardware I already had. Total cost: $0 Setup took no more than a few minutes.

Obviously that's not suitable for everybody for a number of reasons, but for me it's totally erased the appeal dropbox or anything like it.
> If they send the tanks and the shock-troops in to Hong Kong, then no one can deny that that's all bullshit.

Of course people can still deny it. Tiananmen Square happened after all. The PRC has never governed Taiwan yet essentially no governments call their imperialism what it is and tacitly accept their “unification” language. At the end of the day countries can argue up is down if money is involved.
That's essentially what the Nerves Project does [1]. You can boot Phoenix webserver serving static files with zero writes. The root filesystem and server code is written to one of two read-only partitions updated using an A/B scheme. Then a separate ext4 partition is RW and mounted to `/root` by default.

The trick is dealing with stateful apps (e.g. sensors) that write continuously. Power outages are painful on SD cards. Lately I've moved to a separate USB drive for writing bulk sensor data with Pi's. Then the application data partition on the SD card can be used for backup sensor readings -- probably summarized data written rarely to reduce chance of SD card corruption. Mostly when I've had SD card issues its with just the RW partition, specifically the database I'm using gets checksum errors. Never had one not boot due to a bad SD.

Though I'm contemplating trying out BTRFS mirror'ing on a single USB drive, though bcachefs looks promising once mainlined. It's cheaper to buy two 32GB USB Thumbdrives (mirrored) or even a full usb based ssd than buying an SD card with a large amount of SLC based storage. The new Pi's will be a significant upgrade in speed with external USB SSD/Thumbdrives.

Headline is misleading. A fair number of launches are pushed back due to a number of reasons and this is definitely worthwhile mentioning in the article itself. But mentioning "on second try" in the title itself is misleading as you can see in the comments where multiple people were led to believe that the first attempt was a failure instead of an abort (which isn't a failure).

"India Launches Chandrayaan-2 Moon Mission" is a more unbiased title in my opinion.

For me there are two killer features:

1) dependent reviews/change requests. I will work on some feature, submit it for review as one CR, and then I can immediately start working on a feature that depends on that. When I submit this one for review, it will be always shown as dependent on the first, and show a diff against master after the first is merged. This also means you can split large changes into multiple CRs, have them reviewed (possibly independently), then submit them all at once. It makes changes across large repos fantastically easy.

2) very powerful rule engine for approvals. It's based on Prolog, and basically allows you to define arbitrary, turing complete rules on what labels added by whom must be present on a CR for it to be submittable. Using the 'owners' plugin, you can also make it depend on OWNER files that define ownership in subtrees of the repository. This can lend to rules like 'product A must be approved by an owner of A but cannot be self-approved; in addition, someone who is fluent in the languages used must approve it, but that can be self-approval'.

Without those two working in Git monorepos is painful. And since I like monorepos for other reasons (like ease of deployment and testing), I like Gerrit, too :).

It also offers, in my opinion, a much better UI for actually reading and commenting on code. High contrast, fast keyboard navigation, marking of files as reviewed and a very readable history of patchsets, comments, approvals, etc.

The learning curve is much steeper than a GitHub PR, as it's a somewhat weird abstraction (CR/patchset vs git commit/branch), but in my opinion it's worth it. I guess it's my general tendency to use less beginner friendly but more powerful tools. ^^

I know that popular opinion in the Twitterverse is that "Redux is dead", but I note that both Twitter and Slack just released major rewrites that use Redux heavily.

I talked about Redux usage stats and comparison with other alternatives in my "State of Redux" talk at Reactathon earlier this year [0], and my post "Redux - Not Dead Yet!" also addresses some of these aspects [1].

Also, quick plug for our current focus. I'm working on some tutorials for our new Redux Starter Kit package [2], and then will be working on tackling additional functionality to push it towards a 1.0 release [3].

After that, we'll get started on a major revamp of the Redux docs [4] to improve the learning flow, better organize the content, cover more real-world usage topics, and teach using Redux Starter Kit as the "default way to write Redux".

What a difference an inch makes! Southwest happily competes with United with very similar pricing yet they have 32-33" seat pitches with some jets using 31" vs United running 32-31" pitches with some seats now down to 30". Weirdly it looks like Jet Blue has even larger pitches, peaking at 34".
Since Jet Blue and Southwest are considered discount carriers vs United clearly pitch isn't exclusively about price. It's also about profit, particularly when Southwest also has wider seats than United.

Seriously I'm glad we had this discussion because despite living in Houston I think I'll by flying Southwest in preference to United from now on.

Probably true, but if the LiIon batterypacks/modules were required to be replaceable, that would keep that benefit while reducing the waste of lights that are thrown away after the LiIon battery degrades.

Though I'm not sure how much of a factor that is - I don't know how often lights are discarded because the battery life because too short versus lights are discarded because someone wanted a newer/smaller/brighter light.

Nah, more like the other way around.

But obviously it depends on what games you're interested in seeing mods and fan projects of. The vast majority of the Mario/Zelda/Sonic/Metroid/Mega Man fan game and game mod/hack scene is basically entirely new games built on the original series' engine.

Some of the stuff you see there is crazy, arguably on par with many of the more well funded open source software found online. Like that project which adds online multiplayer to Super Mario 64, the mods which add MP3 music to SNES games, a Metroid mod which remade Metroid Fusion in Super Metroid with all the original content and an even smarter version of the SA-X hunting you down. Or perhaps Wiimmfi, which basically replaced all of Nintendo's online services for the DS and Wii, then significantly expanded on them with extra features and modes.

It's kind of insane how technically advanced much of this stuff can be, given it's all made by hobbyists in their free time with no hope of ever getting paid.
