Depends on the iron. If you have a powerful one with temperature sensing in the tip (instead of the heating element), the lead free is not worse, just different.

If you have a beaten down cheap soldering iron, leaded is still much easier to work with.

Even according to 'anti-gun' sources you're about twice as likely to commit suicide with a firearm than to be a victim of a gun-related homicide.

https://lawcenter.giffords.org/facts/gun-violence-statistics...

All deaths are tragic, but given that violence overall has been falling for decades, at the same time that gun ownership is increasing, I find it difficult to attribute the violence to firearms rather than to social factors.

I often think about how many of these deaths would be prevented if we took all the 'anti-gun' money and poured it into our health care system to support people with mental illnesses.
He is describing hypothetical people who purposely infecting others with a deadly disease and then laughing about it. This was the bubonic plague. He is not calling for vigilante justice, but rather for government action leading to capital punishment by the authorities. I thought you were referring to some kind of vigilante justice the way Duterte in the Philippines called for people to pick up guns and kill suspected drug dealers with their own hands.

I'm not for capital punishment. But calling for capital punishment enacted by the authorities leads to a debate about whether capital punishment is good or bad, and I wouldn't call into question someone's character just because they support eye-for-an-eye capital punishment. If they were supporting eye-for-an-eye vigilante justice, I'd be very scared.

But capital punishment is a debate that happens every day, and I don't say that anyone who supports it is a deplorable person. I do try to convince them why I think capital punishment is a bad idea, but that's different from calling into question their character.

I think the iron part gets overlooked a lot, cheap/old irons see a huge temperature dip when soldering. Leaded solder handles that a little better and this is what people perceive as "the difference". Once you use propper technique and a decent iron lead-free isn't worse, just different

> If our politicians believed in human rights then why didn't they do anything to stop China earlier?

They did. Multiple administrations held the belief that if they could pull China into the fold economically, then they would open up.

This strategy was literally the opposite of what the US did with the Soviet Union, with the idea that we didn’t want another Cold War.

Clearly it didn’t work, but until a couple years ago, everyone thought it was.

There are a number of modules from Master’s programmes that can be studied as stand alone qualifications[1]. Apply to do one of these modules, do well, continue doing the modules as stand alone qualifications until you have done the maximum number you can without transferring to the Master’s student roll, transfer.

Only a small minority of degrees have modules that can be studied this way. You need to show some evidence that you’re capable of study at this level. For my Finance Master’s[2] a MicroMaster’s in International Law from UCLouvainX[3] sufficed. It’s also difficult to get the Master’s in the minimum two years this way because they won’t let you transfer from studying individual modules to doing the Master’s without your exam grades having been released and being satisfactory, though it is possible to do it in two years if you start with the first session of the year.

The ICU staff is working double shifts and around the clock in plenty of places. They too get ill, plenty of them have already died. It's a bit late to stick your oar in now and make it your mission, I totally sympathize with the intentions but this isn't your fight other than to stay put, tell other people to stay put and accept that this story will not have a Hollywood ending for many people.

This language of addressing each posters as if they personally had this intention is pretty bizarre. It's very much the language of "proper authorities are taking care of that." I don't personally have any intention of jumping but I'm part of a community and part of a situation where the proper authorities aren't taking care things.
It is a bit newer than many of these suggestions, but the Broken Earth trilogy (https://en.wikipedia.org/wiki/N._K._Jemisin) is a really compelling fantasy and tells a really human story amidst an inspired though familiar world. If you’ve felt like you’re reading the same fantasy story over and over, I highly recommend giving this one a try.

This is not a reason to you? Some people might not appreciate the tone of this but, you’re seriously lacking morals if it’s not.
There doesn’t need to be in-built value in human life for it to be valuable. As a species and society, we have chosen to value life and put rules in place to protect it. I find it inspiring that our species decided that, not a deity.

For what it’s worth, there is not one atheistic worldview; the lack of belief in a god is not an ideology. It is nonsensical just like asking about the shared worldview of everyone who lacks belief in leprechauns or Zeus.
Not long ago there was a post about using English language instead of the J symbology[0] but the end result isn't meaningfully easier to understand because of all the prerequisite knowledge of how evaluation works etc., once you've worked that out most of the "line noise" has already sunk in. I think that's a big sticking point against creating a second "inflatable" notation - though there is always Nial[1]

Not entirely an answer to your question, but J provides introspection/help in a pretty direct way via two distinct means, the first is ;: ("words") which will show you the parse of a J phrase (here, a pretty direct translation of the algorithm in the article):

;:'+/s>(s,#v)$/:\:,/v&%"0 (0.5+i.s)'
┌─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬──┬──┬─┬─┬─┬─┬─┬─┬─┬─┬───┬─┬──┬─┬─┐
│+│/│s│>│(│s│,│#│v│)│$│/:│\:│,│/│v│&│%│"│0│(│0.5│+│i.│s│)│
└─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴──┴──┴─┴─┴─┴─┴─┴─┴─┴─┴───┴─┴──┴─┴─┘

Which shows the tokens of the phrase, which can be helpful if you are unsure of where a symbol or diacritic is being used. Inside the J IDE you can get context sensitive help by pressing Ctrl-F1 on a symbol, if you were interested in /: for example, you are directly linked here[2].

I am unaware of a similar tool in K, which should not be taken to mean it doesn't or can't exist. One of the reasons I'm interested in J has been the tooling and documentation available.

I worked for a welding company and a significant portion of the engineering training involved attending welding school, which also included classes about the chemistry and physics of welding. They drilled into our heads the dangers from long term exposure to elements and chemicals in the fumes such as manganese and cadmium, and I even recall them mentioning lawsuits brought upon them that the company won, which I guess somehow disproves the danger. Anyway, if there's one thing I learned it's that I'd never allow my family members to become professional welders if I have a say. That stuff is nasty and a dirty "secret". Not to mention, a huge number of welders develop cataracts, but that could be due to incorrect shade usage and one one's fault to blame but the weldor....which I guess you could point back and say that's a result of improper training. Either way, I think welding is fun and a great skill to have, but I'd never do it for a living regardless of the pay.

edit - I should add this mostly applies to flux based welding such as stick and FCAW
1M (ordered) list of numbers < 10^8 requires 3.16MB of RAM(10^6*log_2(10^8) bits). The theoretical lower bound to store unordered numbers is 0.96MB(log_2(comb(10^8+10^6-1, 10^6)) bits. Basically calculating number of different possible types of lists, taking its log is the entropy. Both the lists [1, 2] and [2, 1] are same if we don't want the ordering information. In the second case we just need counts of number with property that count[0] + count[1]+...+count[10^8] = 10^6 as counts give perfect information for the sorted list.

Poetry on Pandemic Corona-Covid 19 – facts how we as a humans failed
How do you imagine a de-centralized supply system, with each urban area's cell optimized for 40% of produce going to restaurants, would respond differently?

You're absolutely right. De-centralized systems can definitely respond better to local disturbances. Conversely, they're sometimes more vulnerable to larger scale disturbances that can more easily overwhelm the capacity of smaller systems to absorb shocks.
Landedcost.io Commerce Platform: Only storefront with native import duties/taxes
Well, I guess nothing qualifies then, because you can't have a WCET on commodity hardware. You'd have to have a CPU without any kind of cache (branch history, TLB, etc.) and without any kind of instruction scheduling. You couldn't even have two cores sharing a bus, either on chip or on the motherboard.

Due to the above, security is also in question. Spectre and related troubles take care of that.

Most people have a very different idea of "general purpose operating systems". It includes Linux.

Microkernels have huge problems. Reality disagrees with Andrew S. Tanenbaum. Simplification of components does not come free. Those simple components can have fiendishly complex interactions with each other. Some proven-secure microkernel systems are really insecure because all the buggy code has been shoved into parts that don't count for the security audit. Practical data structure choices become very limited, killing performance. Context switches have always been costly, and the situation has suddenly gotten far worse because we now require Spectre mitigation.

Remember also that performance problems are energy use problems. You might be willing to tolerate slowness, but consider battery life and the power fed into huge server farms.
I have talked with scientists about the risks of bugs in dodgy software written by inexperienced grad students, or themselves. They have uniformly considered it entirely a non-problem. Their reasoning was that either the results would be replicated (good!) or wouldn't be (fine!). Either way, nothing to waste time worrying or doing anything about.

It did not lead me toward confidence in the reported analytical results of experiments.
I get your point, and in large parts agree with you, but sometimes it's just nicer to have a video to watch (especially if there is also an important visual component to it) than reading the equivalent script.

> Some humans are bad narrators, of course, and the machine-generated voice may not be worse by comparison. The problem is I'd just rather not listen to an emotionless voice -- whether it's machine-generated or human -- read a script, I'd rather just read it myself.

If it's in the end really just a script that's read off, I'd rather have it auto-generated. You are right, there are some people that are "bad narrators" on a technical level (looking at you, people in the CircleCI Youtube ads, which prompted me to start this project), but even "good narrators" like e.g. the guy from the Kurzgesagt videos, often times don't convey any more emotion, and could be replaced with an auto-generated voice.

> Maybe I'm wrong and the generated voices are much better than I've heard (any examples?)

The best one in my opinion you can get of the shelf are the Google WaveNet[0] ones. They are the least "tinny" ones with good pronunciation. Out of the open source ones, Mozilla TTS[1] has some very good results[2], but like all other open source ones it's very hard to get running, and even then it has a much more limited featureset (languages, pronunciation, etc.). Happy to hear suggestions here!

I think we've already crossed a point where the quality is good enough for a lot of applications (= it doesn't distract from the script through constant wrong pronunciation), and the future for the field is looking pretty good.

Adapt or die just doesn’t apply to really big government funded stuff. I’m a bleeding heart liberal and understand the undercurrent of current pushes for Medicare for all, but I also worry about this kind of shit. State schools don’t have to compete?
It’s actually too flat in Seattle.

We’ve flatlined at about 100 new cases a day. At that rate, we won’t get heard immunity for many decades.

If we raise quarantine in May it’ll just start spreading again, and we’ll have kicked the can down the road.

I think we should start considering letting young, healthy people return to public spaces, should they so desire.
It's really not that complicated... to watch your own spend. But yet everyone here keeps running into issues, and that's just with your own projects. I'm sure you can at least appreciate the complexities involved at the scale of AWS where even the minority use-cases matter.

"Everything except for persistent storage" is nowhere near useful enough to work and can cause catastrophic losses. Wipe local disks? What about bandwidth? Shutdown Cloudfront and Lambda? What about queues and SNS topics? What about costs that are inseparable from storage like Kinesis, Redshift, and RDS? Delete all those too? And as I said before, what happens if you set a budget and AWS takes your service down which affects your customers?

It's easy to say it's simple in an HN comment. It's entirely different when you need to implement it at massive scale and that's before even talking about legal and accounting issues. There's a reason why AWS doesn't offer it.
You and your fellow churchgoers risk unnecessary car accidents that could result in someone needing emergency attention amid a national health emergency where facilities are overwhelmed and doctors are providing care without necessary equipment.

Continuing to attend a church service, even from your car, is selfish, childish, and amoral. Stay home and stop looking for loopholes.
It reads to me like you're saying: if you're going to spend $400k/month on storage cost, why not pay for a network buildout too? I don't think that allocating X per month for op-ex implies that you also have Y amount of money to spend on cap-ex... especially if you don't own the location. 350kw of power is just another trailer to pull up.

(1) that is the precise definition of opportunity cost. It is everything you forgo the opportunity to do whenever you choose to do anything. Whether you are choosing how to spend your money, or spend your time, or devote your attention, or expend your energy. All of those are opportunity cost decision. It also includes everything you forgo for any given decision. If you choose to buy a Ford, perhaps the opportunity cost could be that you don’t buy a Chrysler. But it could also be that you don’t eat out as often, because you have to make car payments, or that you don’t buy a PlayStation. It is all of those things. This is the definition used in the field of economics.

(2) raising prices will always reduce demand, outside of the very specific circumstances where demand is inelastic. Supply and demand is an inescapable law of economics, and subverting it will always result in failures in the supply chain. The scenario you described will also not increase hoarding, it will most certainly decrease it (whether arbitrage trading crops up is a different issue, but one that is completely unrelated to hoarding).

(3) I used the term rationing authority because it was a neutral descriptor. Anybody who acts as an authority on allocation rations is going to be creating the same inefficiencies (though you’d expect the parts of the supply chain closest to the consumers to be the least inefficient)

Most of what you’ve said has demonstrated serious misunderstandings of how the basic principles like supply and demand and opportunity cost works. Your argument that raising prices increases demand should really just be dismissed off the bat.

Relevant quote:
"Because online charter schools already have fully developed curricula that can serve idle students right away, parents of children who attend brick-and-mortar schools might be inclined to transfer their students to the virtual schools. That could have budget consequences for traditional schools because they are funded based on enrollment. If enrollment goes down, funding goes down as well."

You will also see doctors coming into New York from other places to help.
