Small objects are usually hard to see because they scatter small amounts of light. In this case, the ion is illuminated with a laser close to a strong resonance which makes it emit a surprisingly large amount of light (tens of million photons per second). This makes it relatively easy for the camera to detect.

Atoms are about three orders of magnitude smaller than the wavelength of visible light. So for any optical microscope they are just point sources. The finite size spot a camera sees is only due to diffraction from the finite size of the objective. This is also why stars don't appear infinitely small in images.

You're looking for the word "glow". People are (somewhat rightfully) piling up on you because all pictures indeed are pictures of light, whether that light is reflected by an inactive lightbulb or is from its powered, glowing filament.
I think it's just low supply. They were quite expensive so not that many existed to begin with, and then the last generation of SGI MIPS machines were largely cleared out by companies and academia in the mid-late 2000s. Anything left for sale now is either from hobbyists, surplus sellers hoping to cash in on the few niche markets that still use these, or just really late clearouts.

I bought my Octane on eBay in 2008 (it was previously used at Ford), I think it was around $80 and shipping was more than half of that (an Octane weighs ~80 lbs).

I believe the journalist misunderstood this point. Trapped ions do oscillate somewhat, but the amplitude should be way below the resolution of this imaging system. Most likely the finite spot size is due to the finite resolution and maybe some blooming from over-exposure.

When the filament is cold, you can see it because of light that comes from it after having been reflected off of it, rather than having been emitted from it originally; or, if it's dark on a light background, because of light that comes from other parts of the lightbulb after being transmitted through it from behind. In all of these cases, what you see in the photo is light that came from the lightbulb, and all of them are equally legitimately "pictures of the lightbulb", although they might display more or less detail.

Depends on the specific coating, but even the cheapest non-stick cookware is good for 200 deg C. Higher quality coatings are guaranteed for pretty darned high temperatures. For example, Calphalon guarantees their top-end non-stick up to 260 deg C.

I am personally a total baby about the few non-stick pieces I own. The only things they cook are eggs, and I don't let anyone else use them. But that's just because I'm precious about their condition, not because I fear fumes. As I said in an other comment downthread:

> PTFE does emit some uniquely nasty chemicals when overheated, but in mercifully small quantities, and the effects seem to be temporary. If you read up on fluorinated polymer fume exposure, you'll find exactly zero known deaths, only a handful of known injuries, and no firm evidence of long term health effects. Considering that there are millions of amateur cooks out there abusing non-stick pans every day since the 1960's, I'd say that's a pretty fucking good track record.

I like the take, and I think the “separate things that improve at different rates” thought process. That said, I’m beginning to appreciate having _less stuff_. For example, I moved and decided to buy a few Sonos speakers instead of a bunch of loud speakers, and amps, and DACs, and a ton of wires to connect them all. Maybe I have to replace them in ten years, but it’s accumulating less in my life.
I fixed the Chrome plugin some months ago, take another look.

Very nice project! Can you tell us a little about your tech? How did you crawl Amazon's USB listings, did you use their API? And then how did you figure out if an item has the feature you are looking for: What was your parsing and extraction logic like? Finally, how often are you refreshing your index?

I'm always interested in projects that have a clear path to monetization.
I, too, used to dismiss witness testimony as a useless form of data. I've formed a different opinion over time, and I think there are statistically significant anomalies when you can gather a large number of witnesses, even if there is no proposed mechanical explanation in our current paltry understanding of science. This case is pretty unreproducible so I doubt there will be reliable sample sizes in the near future, but nonetheless it's interesting.
Processing the implications of that was the point while reading this that I got really excited to try this out. I wasn't expecting to see so many curiosity-piquing features.
Pretty cool; however:

- it's not opensource, the github repo contains only binaries,

- the main executable binary is encrypted/compressed from
some reason, can't be easily checked what it does,

- one question that came into my mind was why not create a 'dex2jar'-style tool that works with every dex, and then not create a decompiler for java jars? This way the decompiler could be used for both dex and ordinary java jars.

I think dex translates to jar in a straightforward way, because dex is being compiled from compiled java classes.

But nonetheless, the more reverse engineering tools, the merrier (but I wouldn't run this EXE file outside a disposable virtual machine).
There are plenty of devices where this is the case. For example, the ikea devices.

Generally, most HomeKit devices are LAN or Bluetooth based, and theoretical should work without needing to phone home. (Some might stop if they can’t, but that’s an implementation issue, and i haven’t experienced it yet)
Open Source Licenses in 2020: Trends and Predictions
Did they show simulations about what would happen if they fold during flight? Is it just rougher flight with less lift or would they severely impact the pilot's ability to steer the plane?
OK, so I'm genuinely confused about what your objection to global state is. You mention issues with assignment, and so on - those are issues with Python `globals` and variables in the global namespace, not issues with global state per se. A lot of Python programs use global variables in the form of imports, so I don't see anything wrong here. (Pygame Zero's implicit imports could be a point of objection - but it'd be very easy to hack a small wrapper to force students to import the names they need instead).

In terms of global state, I don't see much of a distinction between Pygame Zero's globals and a god-singleton like `World`. Both feature large amounts of implicit state, just off by one layer of indirection. For the vast majority of games, it wouldn't make sense to have more than one `World`. You might want more than one game scene/level/etc. but that's distinct from the overall windowing system, graphics state, etc. which would be stored in `World`.

Well they just did that, didn’t they?
The Goretex membrane itself is PTFE, which as long as you don't overheat/burn it, is a long chain polymer that does not seem to be anywhere near as much of a concern as small-molecule PFAS are. The bigger issue is likely the water repellent treatment of the shell fabric, which at least in the existing technology is necessary for breathability -- the garment can't breathe if the outer fabric layer is waterlogged.

> I am old enough to remember biologists flailing around for 4 years to identify the HIV virus and two years more for slow (two week) test.

HIV is rather fragile, no? It only spreads in specific bodily fluids and shows very little viral load when dormant.

2019-nCoV spreads in air. That's a significantly hardier virus that produces quite a lot of virus particles that are way easier to detect.

In addition, please remember that molecular biology was just getting started when the AIDS epidemic hit. AIDS (1981) predates PCR (1983). Molecular biology and computing have come a long way in 40 years, and we have a lot more tools at our disposal nowadays.
Trust the formula you used at an ivy league college? Come on, that's a laughable call to some unknown expert! I don't care if your ideas come from an ivy league college. I care about the ideas and their quality.

I distrust people that think because something came from a prestigious school I should trust them.
Which is shown by statistics. There are thousands of daily flights over Atlantic & Pacific. Engine failures over the ocean are incredibly rare (I couldn't find any recent ones). Most reasons why airliners choose to divert at this stage are medical issues nowadays. And for the plane to crash not one but both engines would have to fail.
Sonos was great but the more they've dicked with it over the years, the more cumbersome the interface feels, not helped by the visibility of the all-too-frequent update notifications (occasionally modal). I know some portion of those updates are for features my speakers won't even support, but at the end of the day the system seems like a less "transparent" utility in my house and now like another server that's constantly crying that it needs me to 'think' about it. "Smart tech" is best when it's transparent, not needy.

Your experience mirrors my own. While I had hopes that pinboard would stay stable, perhaps even slowly add features over time I’ve seen the opposite. The lack of status page has left me thinking that perhaps I should ping the maintainer to ask if some downtime is planned. Alas their twitter account doesn’t appear to be business related.

I’m on the lookout for a replacement but not many competitors can match the open data format.
Yet they often choose wrong tool for the job. We often see games written in Java, big websites created in PHP, or processing huge amounts of data in Python. Here someone wants to do embedded in Haskell. These are not technical reasons. The reasons for these choices are frequently "this is the only tech stack I know" or "this is easier to learn".
Also, I was pleased to see Erlang :)
It would be interesting to see less accurate statistics on the total CURRENT number of cases rather than this OLD NEWS. Cool for whoever published that, but we need more focus on speed of information dissemination, even prioritising it over accurracy, we're moving at pre-Internet pace here or someone is actively hindering the flow of info...

What makes software patents different from other patents? For example for things like the cotton gin.
> More recent planes are usually ever better (the OG 747 is from 1969!) At the very least it allows the pilot to 'land' on sea and wait for evacuation in zodiacs. So even in the extremely unprobable event that ETOPS failed (the statistical outlier where a plane loses both engines), you'd probably just glide to the ground 100-200km away at most to reach some landing spot.

While I agree with the rest, landing on sea is a terrible idea. That can work on rivers where you have no waves. But gliding onto an ocean with waves will likely be fatal. Luckily, there is no recent case of a double engine failure where landing on sea was necessary (apart from maybe MH370 but we don't know that).
A bit of both.

The increasing specialisation both between and within academic domains, grants-making processes, various forms of gatekeeping and academic jealousies, all contribute to this.

The capitalist-communist antipathy throughout much of the 20th century also created major impediments, on both sides. Each camp was highly ideologically motivated, each used a consolidation of political power to drive academic policy and practice, and each side tended to both cultivate groupthink around certain concepts and mark others as taboo.

The Soviet Bloc notably preempted explorations in biology. The Western states greatly suppressed anything remotely touching on Marxist concepts (of which there is both bad and good). There were some shared areas of neglect (notably environmental concerns) and of focus (nuclear energy, weapons, jet propulsion, and space flight).

The interactions of power, ideology, and academic interests is ... pretty fascinating of itself.

I think people made fun of him more because of the associated elitist attitude. How many people have the time, space or resources to procure a live animal? Though I admit the imagery of someone like a Manhattan broker slaughtering a pig in his 15th floor apartment is darkly comical.

At the same time, I agree with you, he is right in that we've become detached from what we eat, but that goes for all food. Even the idea that something so routine for many people today, and to almost everyone prior to the 20th century, would be an "experience" to most of us in the modern world is just odd.
The dude is 87. That means he was born around 1933. So, for most of the first 40 years of his life, about 1935 to 1973, dollars were a relatively safe investment; by contrast, a significant number of banks failed, losing all their depositors' money, though not in the US. Storing your life savings in dollars after 1973, whether in a bank or in cash, was not a reasonable idea, but maybe he was not alert enough to new financial developments to figure that out.

You yourself foolishly say, "Even in a 1% interest account, [US]$82k would make a good amount of interest to use for spending," apparently unaware that such a low interest rate is insufficient to compensate for even the lower rate of inflation the dollar is currently experiencing. That is to say, it amounts to a negative interest rate, once you adjust for inflation. If you had put a million dollars in a 1%-interest bank account in 1973 and not spent any of that interest, it would be 1.6 million dollars today, worth roughly 0.02 million 1973 dollars, depending on which deflator you measure against.

The family simply believed that they would be safe traveling through an airport, foolishly trusting that the government wouldn't simply steal the money just because they could. This naïve innocence is mirrored by your touching faith in banks, whose willingness to give you your money is also entirely conditioned on the government not simply stealing it — as everybody in my country found out in 2001.

This is precisely the kind of thing that makes people want to use Bitcoin.

My wife just pointed out what might be a spurious anecdote: no Caucasians died during the SARS epidemic in 2003, and none have died so far in response to this novel virus. Is there any data to back this up?

(She was in Beijing during 2003, and saw SARS first hand)
A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyse a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.
