That's the kind of internal information that is seldom disclosed by SSD manufacturers. Toward the end of the planar NAND era there were several notable cases of vendors having to add background reads/scrubbing because data retention was quite poor with tiny planar TLC cells, and there were measurable performance losses when reading stale data due to the extra ECC required to recover the original data. There are also some enterprise drives or array appliances that have documented behavior where after a long period of being unpowered, they'll operate with reduced performance for a while while a scrub is done.

But for normal use cases, you're either writing enough data that everything on the drive ends up refreshed at least once or twice per year, or you're writing so little data that your flash is basically not getting worn out at all and the retention times will be extremely long, so you're left worrying about read disturb errors which are pretty unlikely to grow into uncorrectable errors without a rowhammer-like workload.

I'm pretty sure most consumer SSDs are not doing full-drive scrubs after every power loss, both because I've never seen evidence of that while measuring SSD power consumption and because it would be insane to do given that it is common for the SSD to be completely powered off every time you close the lid of your laptop.
there is a nice digest of hn posts on n-gate.com, you should check it out.
So many people don't even think about number of requests and often want the job to end as quickly as possible. For me, that is thinking short term, I've seen requests per second as low as 4 cause performance issues for a company. If you want to scrape long term you need to think requests per minute. That is unless you're dealing with a mega site then it's keeping a low request per second.
It's possible to be more cynical about this, but yet to come to a more optimistic conclusion.

If the world's great military powers publicly swear off "killer drones" (let's assume we can meaningfully define such a thing), then they will continue to develop them in secret, but they won't use them in every little border skirmish: every Iraq, Syria, Afghanistan, or Crimea. They'll keep them for the big game.

This has two good effects (assuming further development of killer drones is bad). Firstly, those of us unfortunate enough to be caught up in the horrendous bloody conflicts I callously described as "border skirmishes" won't additionally suffer from killer drone attacks. Secondly, development of the drones and the military doctrine surrounding them will be stymied: you can do a lot in the lab but any technology develops so much faster with the feedback loop that comes from using it in anger.

Moreover, if there's a big war we're all screwed anyway. If that's your focus, you need to argue that drone availablity makes a big war more likely
I'm not convinced that it does - making war cheap makes small war more likely, but all the decision makers know the cost of a big war.

Edit: compare to anti-personnel landmines, or chemical weapons. Both of those see less use because of weapons bans. You might say no, they see less use because the great military powers no longer need them - but you're missing a step. The great powers no longer need them, they decry them as inhumane, they sign bans, and then (almost) everyone stops using them.
I don’t believe it is bad faith interpretation. I used a rhetorical technique where you ask a question which shows where a line of reasoning ends up.

The poster said we shouldn’t seek immortality as it goes against evolution. By the exact same logic we shouldn’t lift a finger to medically help people beyond child rearing age. It’s the same argument. And if we really believe that evolutionary incentives define morality, than we might as well cull that population to eliminate dead weight.

Sounds horrific? That’s because our sense of right and wrong has very little to do with what benefits evolution. And as a consequence, evolution has little if anything to contribute to this discussion of whether we should research immortality or not.

Honestly, absolutely not, and I think money would be harmful. Lots of software doesn't need a lot of work. It can be simple. When people get paid to solve problems there's an incentive to add more code, to add new domains, etc.

This isn’t a free marketplace of ideas though - thanks to dubious algorithms and recommendations, not all ideas even have a chance of being seen, let alone the bad ones buried. The echo-chamber phenomenon is like walking into a shop, looking at an item on a shelf from one manufacturer, and then once you put it back and look around you can only see items from that manufacturer. You get trapped in a bubble where you’re only ever seeing content like the content you just engaged with.

I agree that in a free marketplace of ideas bullshit content would get buried, but this isn’t how modern social media platforms work.
> It's not difficult to take user-entered data and just dump it to a log file. I'm pretty positive none of these vulnerabilities exist with System.out.println.

yes, but there can be (and have been) vulnerabilities in terminal emulators, terminal multiplexers, text editors, databases, web renderers and all manner of tools that can be used to store the contents of or view that file. your argument makes sense that the logging library should not be attempting to parse the log strings, but think about all the other millions of lines of code that could potentially try to parse that data as well. patch log4j one day and the next you find a bug in some colorizer javascript library or in the sixel support for the terminal emulator. people add parsing everywhere.

i think ideally that all user supplied data should be sanitized in the strictest possible manner before anything is done with it, including logging.
You seem to have overlooked that this piece is filed in the news section, not the reviews section.

I think it’s because your stats are off.

“The age-adjusted death rate decreased by 1.1% from 731.9 deaths per 100,000 standard population in 2017 to 723.6 in 2018.”

https://www.cdc.gov/nchs/products/databriefs/db355.htm

So that’s an overall death rate of 0.7% in the US pre COVID. If the death rate becomes 1%-2% with COVID, that’s an increase of 50% - 200% in the number of people dying.

That’s … not negligible.

Whether you think that should affect your “quality of life” I think depends a lot on your level of empathy.
This deadly racket uses letters to send Fentanyl and more dangerous drugs to dealers in the USA. Pure Fentanyl has a lethal dose in the average male of 2 milligrams. This is a small quantity. 1 gram will dissolve in 40 milliliters of water. The drug sellers then wet paper with the solution, it takes a few sheets. Then they dry it and laser print data sheets for anything and you will have 1 gram spread evenly through the paper, might be any data at all, the object is to make it pass inspection after it is mailed as innocent data sheets.
The USA buyer then washes the paper repeatedly with water - using repeated small amounts of distilled water. It might take 10-20 washes, one after the other, and it is then dissolved in the water. Then they have a solution they can evaporate to dryness, and they will recover almost 1 gram as a powder. With a laser printer very little black ink dissolves as particles, but if there are, it can be filtered before they dry it. If they use unsized and non glossy paper, and distilled water, the purity will remain and the final dry powder will remain potent. They then sell it. Since milligram doses are a nuisance, they often mix it with a powder - here is where the fatalities occur. It is very hard to make a uniform finely mixed powder. Drug companies have detailed procedures to mix fine powders with safety and uniformity, so they avoid any lumps. A lump can kill a person. Once they have their powder, perhaps they now have 1000 grams with a gram mixed in it - each gram of powder = 1/2 fatal dose. They then get a pill press and make 10,000 pills of 100 milligrams each = the same gram is now in pill form, with 1/20th of a fatal dose in each one. If the mix was well done and tightly pressed(the mixing powder will be chosen to make pills that are strongly bound as pills) they have an item they can sell, telling the buyer what is in each pill.
All is well - unless there were a few lumps in the initial separation = a few dead buyers/customers/addicts etc. There are some Fentanyl derivatives that are 15 times as toxic = smaller lumps can kill. The first class mail path is the safest, but most time consuming mail method. Expresspost is faster, but it is inspected more closely. There are other bulk methods, as listed on the DEA website here.
I am a retired chemist and the only way to deal with this on this side is rigorous inspection of the mails letter by letter with testers (which can be trained rats or other animals that can detect any drug odor - if at all possible).
China clearly does not have the will to rigorously deal with this problem, but they do have the power - if they are persuaded it is in their best interest?

> IP addresses are getting even more temporary with IPv6

That's true but kinda irrelevant. IPv6 is at best as bad for privacy as static IPv4 since you're assigned a fixed range, so the adversary can both identify you by the static part of your address, and possibly resolve devices behind the router which would be hidden by NAT in IPv4.

Code auditing is extremely expensive. I recently did some napkin math and my estimate is that for our relatively small project (a company of ~10) it would cost between 2 and 12 million dollars to have our rust dependencies audited, with Rust making up ~60% of our codebase.

And that's a point in time audit. To maintain that value we'd have to redo the audit periodically.

It's just not gonna happen.
> Sounds similar to CIA "black budgets."

Good comparison. Other federal organizations have these, too. Many NASA launches have a black project that the public does not hear about. We should probably change the phrasing from black to something else, though.
Scraping as a service can be profitable if you target people who are looking for leads to cold email/spam. Lead gen is one of the few areas you can easily charge $100 as your entry level package and at that price it's very easy to make money if you have half decent marketing.
The amount of this behavior on eBay is also pretty stunning, however the rules that have been proposed to curve this basically stand to completely destroy secondary markets which is horrible for single use electronics consumption and the environment in general.
I believe yes, because it's unavoidable that any mature forum settles on an overton window, accepted ideology, however you want to put it.

I deal with the overload by being a "slow" thinker. I figure that nearly anything worth knowing, will still be worth knowing in a week. The noise will be gone.

It helps to be Old. For instance I have good statistics on the percentage of cases, where I've looked back and regretted supporting a particular party or candidate in an election. This gives me a good handle on whether I need to rethink my political views urgently, or if I can wait until after the next election cycle.

yes, and python has a large amount of analyzers:

> Which world events do you consider important and directly relevant to yourself?

I find this kind of view depressingly common. Knowing about world events breaks us out of our various bubbles and makes us aware of what is going on with our fellow human beings. It is short-sighted to only focus on things relevant to you at this moment.

And irrelevant to what? Your career? Social standing? If so, then throw away movies, all fiction books, etc. those don’t result in anything really actionable either.

(This isn’t an argument for up-to-the minute news, though. I sort of agree there.)

We'll have to disagree on the shape of the curve I guess, it's just my personal take.

For what it's worth...

I've been to Ephesus (which is amazing, I'd like to check out Pompeii as well) the armory in Venice is one of my favorite repos of old cutting edge tech and having spent time in Rome, truly their achievements are amazing and the Pantheon absolutely blows my mind, it's no wonder the village dwellers believed the God's lived in Rome, I would have.

But harnessing the power of the atom, understanding fundamental physics, biology and sound/light speed global communication... and the technology that these things have enabled (including my own living past 3 years of age due to modern medicine) is truly a leap, in my opinion the Roman's and those brilliant technologists and logistics civilizations of the past were still closer to living in caves by modern comparison.

I would not have wanted to live back then and I literally couldn't have. Our recent exponential explosion certainly depends on their hard fought knowledge, but in my reckoning even their best tech and logistics are deep in the early part of the curve.

Turkey has already developed their own autonomous killer drones (which have in fact killed people, in Libya). So any country with their GDP and level of technology probably could too.

According to Wikipedia, Turkey has the 20th largest economy, and 72nd by per capita GDP. So a lot of countries could develop this technology if they wanted to.

Meditation retreat to reflect

Take some time before big decisions
In early high school, we'd ride bikes to the local coffee shop, lean them against the big windows out front and hangout. Somehow, no one noticed when mine was snatched one evening. I was pretty devastated.

My grandfather drove me around the town the next day to see if I could spot it. When we were about to give up, I noticed a bike leaning along side a house near the shop. I could see it from the street. It looked exactly like mine. It had the same replacement seat and even a curly bike lock coiled around the handlebars on the same side I left it. But it had been hastily spray pained.

We called the police, they arrived and a kid inside noticed the commotion and came out. They had found the bike at the shop and took it. I went to inspect it. I was very surprised when I found the small yard behind the house was packed with around fifty bikes. To the cop, I said something like, "there's tons of bikes back here!" I then remembered another friend had theirs stolen as well.

He didn't look for himself, and said I couldn't just take the bike. There was no proof it was mine. So, I said, "what if I can unlock the bike lock?" I could and was allowed to take it, but it had been ruined. My prized shiny bike had been banged up and spray painted.

The following week my mother read me a letter that had arrived. The town would not be prosecuting the kid. I was confused. I did nothing wrong and stayed out of trouble myself. Did their actions not warrant any consequences?

My mother ended up going to the police department and insisting the town prosecute, which they ended up doing. I'm not sure what happened. Did the consequences dissuade them from stealing a 51st bike? Their family had failed them, would their community? If not for religion, what hope did they have?
Wait... Is this correct? Do you have a source? This is the first that I've heard of this being directly measurable.

Note Robert Harper, the author of Existential Type and one of the big names in ML, has a bizarre crusade against Haskell.

I find it weird that so many of his articles seem to be lashing out against (the internet perception) of Haskell, almost a popularity contest between ML and Haskell, when the adoption of either language is marginal and could use some cooperation between the two, instead of framing it as a zero-sum competition. ML and Haskell are allies, not enemies.

This obsession is a shame, since Robert Harper is obviously an intelligent person. I remember some of his feuds with people from the Haskell community were... embarrassing.

Most feuds are embarrassing. The proglang community could do with fewer of those.

I don't remember Simon Peyton Jones ever speaking ill of ML, for example. There's an example to follow!
