It's not currently, but I'm planning on adding that feature in a future version along with making shell metacharacters like `>` and `|` act much like they do shells when they appear inside of Julia command literals. When we do that, we'll be able to support splicing Julia functions and/or tasks into pipelines.
But Visual Studio is not C. It's C#, and even it's C++ parts would be somewhat com-ish, dot-ish. I'm sure Microsoft is well prepared for 32-bit -> 64-bit transition. My guess is that there are probably massive amounts of plugins (not done by them) that are not prepared, especially ones that have to use native code. So Microsoft can't say No there. Just guessing, I dont' know for sure.
Not with that attitude, we won’t. The ozone layer disaster never materialized because we fixed it. Giving in to fatalism on this is deeply disappointing.
The AEB wouldn't trigger on something like this. And it shouldn't, since an actual driver would be turning to follow the road, so there is no reason to do any emergency braking (or even to warn them).
Right, but that's the gist of what I mean - I don't think 'macOS update that suddenly and irrevocably kills most of your Steam library' is on the horizon.
Not much of a life you’re leaving your kids.
What are you talking about... Why would you write a kernel in C++ instead of C? You want fine grained control over what the machine is doing. Imagine dealing with all that bullshit C++ comes with when trying to write a kernel. And then you’re trying to figure out if this C++ compiler you need for this architecture supports dark matter backwards recursive template types but it only supports up to C++ 76 and you’re just like fuck my life

I did think about that. Though, as a driver, you're supposed to leave enough room for this to happen, I know that's not reality so point taken. With early enough 'im confused', perhaps it can just blare an alarm and disable auto drive. Still, given the option between the two, I'd choose come to a stop vs any alternative. It's what a human would do if they lost all visibility.

There’s also no way that any amount of your preparations will materially improve your chances. If you stockpile, and civilization collapses, you will be raided for your stockpiles by stronger, better armed people. There will always be stronger, better armed people. If you prepare to live off land, how is that going to work when the land is dead?

There’s no escape for you or your family, except averting disaster in the first place, or death. Unless your prepping amounts to a suicide pact, then it’s just a fantasy to keep you from being too afraid. As comforting fantasies go, prepping seems like a particularly expensive and time-consuming one. Unless you’re desperate for the illusion of control, your time and money is better spent elsewhere.

"This example nicely highlights the importance
of isolating individual behaviors to understand the
contribution of parts to the overall function. If we
had been able to isolate a single function, maybe

could have produced more meaningful
results. "

If you had any Android developer experience, you would surely know that Google had a few failed attempts at real time audio, needed help from Samsung to implement them, and the final API was C only, with devs asking for a C++ one, wich was later dumped on github as side project and isn't part of the official NDK APIs, but alas you don't.

but a big part of AEB is to slow the car before a collision, thus reducing the speed/severity of the resulting crash. There certainly should be a point at which it becomes clear that the car is going to hit the thing, and I'd expect the AEB to reduce speed at that point, even if that is too late to completely stop the car.
Tesla is recklessly using its own customers to train their fleet for level 5. AT BEST their response is, drivers need to be 100% as attentive as they would without autopilot. What then is the point of autopilot, except to train the fleet?

They are in complete denial that autosteering can seduce reasonable people into lowering their guard and mentally relaxing. Again, what other immediate user benefit would it provide? What would a reasonable person expect autopilot to do?

Isn’t it contradictory to offer an automation feature while claiming that legally it does ZERO automation for you?

Note: collision avoidance and emergency braking are on by default even without autopilot. “Autopilot” here really means the autosteering feature.
This is particularly heinous for those of us that do music production. A lot of plugins are orphaned at some point (meaning the developers no longer update them), and if you created a piece of music with those plugins (instruments, effects), if you can't load those plugins, you can't open old files.

I often open up sketches from several years prior and consider working more on them. I keep a full 32-bit stack of music stuff left installed exactly for that reason. Usually, if I open them up, then I'll go ahead and move them over to 64-bit semi-equivalents, but that's difficult if you can't even hear what you were doing with the old one.

It's not just the low volume - it's the airtight seal. A very low frequency sound wave is a slow sequence of low- and high-pressures. With an airtight seal, it's much easier to sustain pressure differences from 1 atmosphere from a long time. With no seal, the high or low pressure leaks away from the region near the ear.

This is also why open-ear headphones tend to have lower bass response than closed-ear headphones. For example, compare these frequency response curves:

http://graphs.headphone.com/index.php?graphID%5B0%5D=853&gra...

The open-ear Sennheiser HD650 has around 10-12 db lower bass response than the closed-ear Fostex.

Even more dramatic, look at the dynamic response to a 50hz square wave - the Sennheiser's amplitude drops completely to zero before the next jump of the square wave, while the Fostex manages to maintain about 1/3 of the original air pressure in the headphone cup by the end.

> I'd choose come to a stop vs any alternative. It's what a human would do if they lost all visibility.

As a human who has driven in central valley fog? it's not what most humans do. I personally pull over if I can't see two seconds ahead while going above 45, because most people are still going 65-75mph even when you cant see the lines on the road 20 yards in front of you.

I'm also uncomfortable with that, afraid someone will plow into me. But that's better than plowing into someone else, I think (though again, I think I'm not in the majority in that assessment.)

One thing I often do is wait for a tractor trailer to pass me... then I follow them just close enough to keep their taillights in view, on the theory that I can probably stop faster than they can, and they are lit up pretty well, so I can see them further than I can see other cars.

Why? If I may ask. Is there still a lot of video out there that only QT7 supports?
Don’t know about Arrow, but Parquet is a columnar format. Such formats can’t write record-by-record, they need a large number of records to shred into columns in order to realize their columnar benefits. In contrast, appending to RecordIO is little more than writing a binary string. The downside of RecordIO is that you can’t just read some fields in a message and not others. You have to deserialize the whole message. RecordIO is cheap to write and well suited for cases where reading the entire message is not that big a deal. Columnar formats are more suited for the cases where it’s ok to pay the relatively substantial up front encoding cost for vastly greater performance in analytical workloads. Advanced ones contain additional metadata (such as range and hash constraints, the former can be both per file and per block) which the analytical runtime will be able to take advantage of in order to avoid doing the work that doesn’t need to be done.

Verkada raises $15M Series A
The main issue would be that 64-bit may cause an app to use more memory. Every pointer doubles in size, the alignment of a structure containing a pointer may grow, etc. Basically, if you needed a lot of structures allocated and they all grew, your memory use becomes noticeably bigger.

Sometimes legacy code can make assumptions about pointer size. These hacks were more common in the days of porting older systems to 32-bit but it could still happen moving to 64-bit.

If there’s code that tries to manually populate the bytes of data structures, sometimes bugs appear when the target field size changes (e.g. somebody ends up not initializing 4 of the 8 bytes in a now-wider field).

In the case of Apple, the huge pain will be their decision to not port all of Carbon to 32-bit (despite Forstall getting on stage years ago and stating that Carbon was going to be 64-bit “top to bottom”, it never happened). This can mean addressing a whole pile of nothing-to-do-with-64-bit-whatsoever problems before even starting to solve 64-bit problems.
That sounds a little bit like survivor bias to me. Nothing bad happened to the US, but in other countries shit went down in the last century, stuff that if you were not informed and aware about, might lead you to... for example go to school in the morning and realise you can't go back home since you're on the other side of a new border.
1. Yes, the buttons are powered by CR2032 batteries, and when the button is pressed an LED lights to let you know it worked. (i.e. You can detect when they're empty.) My batteries have lasted for several months so far, but I don't know how long to expect them to work.

2. Not sure what you're getting at here; anybody "local" could probably overhear the transmission. And probably perform a replay attack.

3. There is no feedback on the buttons, you press the button and they send a radio transmission (+ light the LED). There is no facility for two-way communication.

If I were building the buttons myself I'd probably have them both send and receive, such that you could use an ACK system. But the whole point is to use cheap & off-the-shelf parts so ..
I gave up ReSharper in 2015. It's a great tool and I miss it, but our solution has nearly doubled in size over the past few years and even vanilla VS 2017 struggles with it. We have dev ops working on nugetizing some of the bloat and Microsoft premier support is helping us to understand why our solution is so stressful on Visual Studio.

The in process limitation is a real killer for ReSharper.
Find me the casual opportunist in the apocalypse; it would all be starving lions, and a lot of lions. If you want a preview, study famous famines and sieges, like the siege of Stalingrad, and the Holodomor.

The oldest Macs that support Sierra (10.12) or High Sierra (10.13) are from 2009. You may be able to bypass these restrictions which are often based on graphics chips through kernel extensions, but discontinued support for 32bit probably has much more to do with older software than older hardware.

If you want to find unusual problems with older Apple hardware for the sake of reusability, take a look at the firmware from around that time. It was just weird enough to make it similar to standards but often too difficult to support a decade later. In a decade, people are going to say the same about the not-quite NVMe SSD interfaces in current Macs.
Actually I didn't realise they still made them... Nice to know. I remembered the Foveon sensors from when they were first introduced, but didn't see any reference to them still being made when I did a quick search to refresh my memory, so they may have a bit of a marketing issue ;)

Also with Apple forcing the user on the rolling release treadmill, its rather annoying that one can't simply stay on a stable version.

Then I seriously don't understand why so many tech workers want to lower the bar for entrance into the profession and induce higher supply of tech workers. What they don't realize is that that won't make lives better for the new tech workers - it will just make it worse for existing tech workers (just like what mechanical engineers or lawyers went through).

This is probably the biggest con pulled by tech companies - play on egalitarian tendencies of tech workers to induce more supply and thus gain additional leverage over employees.

The way we define area is in terms of little squares. (We could use little equilateral triangles or little right-angled isosceles triangles or some other unit instead, but we don't, conventionally preferring squares.)

So the way to learn about areas in general is to start with the area of a unit square = 1, and then clarify the properties of area in general, notably that we can cut and paste shapes without changing the total area, as long as we don't overlap them, which means we can count up the number of unit squares and that tells us the area of a figure. Most of the rest can be figured out by students if guided by a well organized set of problems which build on each-other.

We can proceed to first finding areas of shapes made using axis-aligned sides of natural number lengths on a square grid. For these the area can be found by directly counting squares, and e.g. by natural number multiplication in the case of rectangles. Then we can look at the areas of other shapes with vertices on a square grid. Then we can look at the areas of rectangles with rational side lengths (no longer nicely on the original unit grid; instead we need to make a finer grid to count, resulting in rational-number areas, since we must relate the grid units). Then we can next proceed to parallelograms – in a square-area-unit conventional world these are arguably more fundamental than triangles, but we could deal with right-angled triangles at about the same time. Triangles where we can find base and height can come next; these can be split into a pair of right-angled triangles or duplicated and glued into a parallelogram. After that finding areas of other shapes (e.g. with irrational side lengths) takes more machinery from Euclidean geometry (starting from the Pythagorean theorem), and can be delayed a while.

While talking about parallelograms it would be nice to take some squares and other rectangles outside and look at the shadows they cast on the ground. This is a nice chance to introduce the concept of affine transformations, which preserve parallel lines and area ratios, as we can see by observing the shadow cast by a square grid (e.g. made of wire or drawn on a transparency sheet), especially if we have some translucent shapes lying on the grid. Basic transformation geometry (especially discussions of reflection/rotation/translation [isometries] and snowflakes, wallpaper tilings, etc., and affine transformations) is accessible at quite a young age and some hugely valuable topics to introduce early so that kids will be prepared to extend them later. More general projective transformations can wait a while.
> Our climate has been extremely stable for a long time

Depends on your definition of "stable". We have no data on most aspects of the Earth's climate for most of human history. For example, we don't know what the frequency of storms was for any time period further back than a century or two (and the data is spotty further back than a few decades). What data we do have suggests that the 20th century was a period of unusual calm with respect to many aspects of climate, and that what we are seeing now is just a return to what has been normal for most of the period since the last Ice Age ended.

Even the findings presented in this article are limited: 1600 years sounds like a long time, but the last Ice Age ended 12,000 years ago. What has the AMOC looked like during all that time? We don't know.
