> Even with bypass services, cheap is not the same as free, especially at the scale spam runs at.

Spam doesn't scale on a small site. Say you can absolutely fill a small site with spam comments to the point that 99% of comments are spam. Very few people visit the site (it's small after all). Fewer still read the comments. Virtually none of those will click on the (usually obvious) spam links. And still fewer will buy, making you money. If you spend 2 hours customizing your spam script to circumvent anti-spam measures on a small site, you might as well flip burgers at McDonald's, you'll make significantly more money.

Spam works at scale only when you're not customizing. I'm involved with quite a few small to medium and a few larger sites (the largest getting around 4m PI/month) and though we use WP we get virtually no spam because of trivial deviations. We get an immense amount of attempts though. The little we do get is obviously manual spam: in the correct language, with content targeted to the individual page/post content (beyond "very interesting article, I wrote about the same" one-size-fits-all).
Biggest pain with ReCAPTCHA is since I've switched to Brave. Sometimes it's 4 to 5 ReCAPTCHA forms coming up until the system is satisfied I'm a user.
Mostly sensationalism. What the hells a "social platform" anyway?

Fortnite is free and accessible (pc, mobile, console). It's a popular game, but like all games, the attention will eventually fade and players will move on. The user base will get older and have different tastes.
On a related topic, what are other's favorite learning resources for applied distributed systems?

I can't figure out how to delete this. Pretend I didn't say it.
> I am much more confident in ReCAPTCHA of stopping bots compared to any roll your own solution.

I am as well. We enabled Recaptcha on one site and had spam signups drop by 99%. Unfortunately, regular signups also dropped by 20% because people give up when they hit Recaptcha and don't absolutely, seriously need what it's protecting. To us, joining the arms race against the spammers (which, so far, we've easily won) was much more profitable than turning away legitimate customers.
Good transparency here, an appreciated and professional online reaction to criticism.
> You can't have a company without money and people. That's literally what a company is.

To reiterate my point by playing off your statement: you also can't have a company without a product or service (unless you are Enron). Budgets and hiring are very important, but not core. I have to respectfully disagree.
fair enough. You're putting more weight on the harm of arbitration agreements, whereas I'm putting more weight on the harm of identity theft and phishing/online scams.

I would say that more broadly speaking the harm of arbitration agreements is solvable in other ways, such as government or advocacy actions. I'm guessing that's what led to this letter/form in the first place: some regulator, or litigation resulted in Chase having to provide an "opt out", and they fulfilled their requirement by making it a mail-in form to discourage opt-out.
If the harm persists then consumer advocates, elected representatives, and regulators can take another crack at it.

Educating people to be wary and careful with personal information is trickier. It's hard enough to spot a very well crafted spear-phishing attack, even when you know better and are generally vigilante. I don't know how else to deal with that except hyper-vigilance, and yes "this behavior is wrong in all circumstances, period,"
But again, I guess I'm weighing that risk higher than you are.
> In legal filings, Google has disputed that conservatives are an identifiable class under the law. In a decision, the judge on the case said the court “indeed has doubts” about the viability of the idea, but it is, for the time being, letting the case move ahead.

Isn't this the main argument that is used to defend gerrymandering? That since political ideology is not a protected class, it's okay to redraw district maps that discriminate against a particular ideology?
No, servers are lower speed because they have more cores and larger caches. Both of those take up more die space, which makes routing higher-speed clocks harder/impossible.

This is easy to prove. The highest clock rate xeons you'll find are a special SKU exclusive to aws. Sure enough, they have far fewer cores than instances with lower clocks.
The golf industry disagrees. Lack of leisure time is one of the key factors driving the steep decline in the golf market.

OK, that works, but it does seem dumb, or even deliberately obtuse.

The language could just as well recognize Node as it recognizes 'Node', but instead it given as a burden for the human programmer to handle.

Is it maybe because mypy is not really part of the Python language, and can't really make changes to it?
Yes, but man-portable, AA and anti-tank missiles, and sub-launched ballistic missiles, are not carrying quarter-of-a-billion dollar satellites. Typically, you don't want launch vehicles to have to withstand heavy loads not related to actually flying vehicles into orbit. Ground support stuff is not supposed to impose design loads, but I would imagine that firing the launch vehicle out of a cannon would actually impose high enough loads to cause engineers to design to those loads.
It's all still down there somewhere....

The whole site is a great collection of stories about 'unexplored' Ukraine. Their project idea is like an ethnographic expedition, visiting diverse destinations in Ukraine to collect/record people stories. Amazingly, the written content is also very well translated.

A true gem, especially given the uneasy times people of Ukraine are still going through.
There's something awfully tone-deaf about a conservative magazine using John Updike, Sinclair Lewis and Philip Roth to bemoan the decline of country clubs. These men's works (American Pastoral, Rabbit, Run) excoriate the culture of the 50s and 60s rat-race-to-the-country-club.

The fact that the literature of the period employs the country club is not evidence of the country club's positive aspects -- it's frequently evidence of the exact opposite.

This reminds me of being stranded in another country trying to charge my smartphone via solar. If I still had power, I could charge it, because I could enable energy saving, airplane mode, turn off the screen, etc. It would slowly charge up.

But if it was completely empty? It would permanently set the display at max brightness politely informing me it was charging, that I had to wait, and would actually drain more power than the solar panel could provide.

I eventually had to pop off the back case and physically detach the display cable to get it to charge up.

I always wondered why it displays anything at all when out of power, just a flashing pattern of the LED would have been enough, many portable chargers use that exact method to read out the charge, usually in 25% increments.

I am not associated with PingCap in anyway, but as an open source user & contributor myself, I find your comment quite offending. You raised the exact same issue 2 years ago on NH [1], that issue got fully addressed by both PingCap's core team member and other NH users. Without bringing in anything new to the problem being discussed, you chose to repeat the exact same stuff that has been fully addressed 2 years ago.

Sure, you might had the feeling that you were not treated in the most friendly way, but after 2 loooong years, after the feedback from PingCap's core team member, maybe time to just move on? If you really find PingCap is not friendly enough to the issues you raised (which is never the case to me or anyone I am aware of), you should probably start your own much more user friendly open source project and set an example for everyone.

Probably not so talked about because, in my experience, it barely works. The bridges I've tried to install were either largely outdated for either matrix or the service it's federating to (Discord for example), or dropped a lot of messages going through (Slack, IRC), or had incredibly annoying limitations (SMS, Hangouts). I don't see how that is a "killer feature" if it's barely developed.
Ask HN: Good tech talks on how analytics systems are implemented?
I am doing a new sub-system, for analytics, which I can design / implement from scratch. I get a bunch of unique users (say a few thousands). Now I need to track each of these users and do some analytics (Which places are they logging in from ? How long do their sessions last on average ? What are the usual links/endpoints that they visit ? etc.) in my API server. I have a few thousand active users and about two dozen parameters on which I want to track and analyze these parameters.

I have never implemented such an analytics type system. I want to learn about people who have already implemented similar systems. Are there any good tech talks, engineering blog posts, video courses, etc. that highlight the design/technology/architecture choices and their benefits.
It has to cause a huge amount of single-bit errors to find a spot suitable for a three-bit error.

If these errors are actually treated as errors, then chips will be disabled or processes will get blacklisted long before they can be used to exploit.

Nice post that you shared! I think with the trend of more urbanization, upper-middle class millennials have substituted some of the aspects of country clubs (social community mixed with athletics/sports) with expensive boutique group sports and fitness experiences like CrossFit, SoulCycle, and perhaps Equinox. Some of the true upper class friends I have still do things like pay dues for expensive social athletic clubs.
I agree. My first interviews were like "You have no clue about C but you are good at FORTRAN and you are smart. No problem. You'll pick it up in a second. Read this book before you start.".

Frankly I’m skeptical - is the article talking about high end private clubs owned by their memberships, or the corporately owned “country clubs” or clubs associated with a real estate development or planned community? They are two totally different things...

It's a normal distribution around 4-8 hours. There's no correlation with hours worked to seniority.

I specifically included meetings, etc, in the time counted.

If you took anecdotes from office workers IRL you'd think everyone was in the top quintile. You can argue that its an unrepresentative sample (people browsing HN) but I'd postulate that people not on HN are using downtime elsewhere.
We still have Peter Hitchens, who won the Orwell Prize for Journalism in 2010[0], two years before his elder brother was memorialised in 2012[1]. The two disagreed vehemently on a great deal of fundamental stuff, but Peter posseses all of Christopher's independence of mind, perhaps more, and has plenty to say because of that.

Yeah. In the 90s I met almost no computer scientists. We all came from different backgrounds and got into programming because we were interested and liked it. Now we have a lot of people who chose it as a well-paying career. Nothing wrong with that but it's less fun.

The Tsar Bomba is the most powerful weapon ever detonated, and that was in 1961. Interestingly even that weapon back then had a 100 megaton design. They decided to scale back the tested payload for a variety of reasons including enormous fallout and that testing such a massive weapon would be a suicide mission for the pilots dropping it.
I’ve got a variety of 50p bags from Asda, Waitrose, Tescos that I still use more than a year after I bought them.

I’ve never hired someone who was self-taught, not because self-taught people can’t be equal or better, but because you’re trying to buy security and stability. The most expensive mistake you can make as a manager is hiring the wrong person, and self-educated people just aren’t worth the risk when you have a dozen other candidates who are great. I’m Danish though and things are a little different here because education is free. In face the government will even pay you a small amount of monthly money while you study. So we don’t have that many self-educated people, and those who are, are typically self-educated for a range of reasons that put them at a disadvantage from the get go.

So my point isn’t to discourage you, but to make you aware that managers might see your lack of formal education as a risk that you need to mitigate.

Everyone can learn to program, but learning how to program, correctly, efficiently and safe comes with formal education and you probably need to show that you know at least something about how to make CS based decisions. Maybe you do, if so great. If you don’t, spend a little time researching best practices, read up on design patterns and maybe complete the MITX intro course(s) to CS on edx.org.

I’m not sure knowing a specific framework is really all that valuable. If your can build something with LAMP/JS that makes money then you’ve already demonstrated your ability to write software. On the other hand it wouldn’t hurt you either.

> Interestingly, one of the main themes that hasn't been the focus for any past generation, is how controlling language can control thought, but maybe that is something still to come.

To pick an obvious example, the Department of War was renamed to the Department of Defense just 2 years after this book. I better the current funding would look very different had the change not been made.

Language is controlled via wrongthink, aka political correctness in the initial "adherence to soviet policy" definition, this affected a generation of communists and socialist including Orwell himself. There are also modern version of wrongthink, opinions you can't share publicly for fear of reprisal for better or worse.

Control of language seems to be intertwined with controlling history too, being openly racist is now wrongthink, so history gets rewritten into things like "the civil war was about states rights".

Like the other aspects, it's there just not as draconian as Orwell predicted.
